                SERIES 2003A 7% CONVERTIBLE NOTE DUE JUNE 9, 2004

         THIS Note the duly authorized Note of INVISA, INC., a Nevada
corporation, having a principal place of business at 4400 Independence Court,
Sarasota, Florida 34234 (the "Company"), designated as its Series 2003A 7%
Convertible Notes, due June 9, 2004 (the "Note"), in the principal amount of Two
Hundred Fifty Thousand and 00/100 Dollars ($250,000.00). This Note is acquired
by the Holder (as defined herein) pursuant to the terms of that certain
Financing Agreement dated as of the Original Issue Date (as defined herein),
between the Company and the Holder, as amended, modified or supplemented from
time to time in accordance with its terms ("Financing Agreement").

         FOR VALUE RECEIVED, the Company promises to pay to the Holder or
registered assigns, the principal sum of Two Hundred Fifty Thousand and 00/100
Dollars ($250,000.00), on or before June 9, 2004 (the "Maturity Date") and to
pay interest to the Holder on the principal sum at the rate of 7% per annum,
which interest shall be due and payable on the earlier of the Conversion Date
(with respect to the principal amount converted) or the Maturity Date. Interest
shall accrue daily commencing on the Original Issue Date (as defined in Section
6) until payment in full of the principal sum, together with all accrued and
unpaid interest and other amounts which may become due hereunder, has been made.
Interest shall be calculated on the basis of a 360-day year and for the actual
number of days elapsed. Interest hereunder will be paid to the person in whose
name this Note (or one or more predecessor or successor Notes) is registered on
the records of the Company regarding registration and transfers of the Notes
(the "Note Register"). All overdue principal, accrued and unpaid interest and
other amounts due hereunder shall bear interest at the rate of 18% per annum
from the day such interest is due hereunder through and including the date of
payment. The principal of, and interest on, this Note are payable in such

                                        1
<PAGE>

coin or currency of the United States of America as at the time of payment is
legal tender for payment of public and private debts, at the address of the
Holder last appearing on the Note Register, except that the Company may, at the
Company's option and at any time, pay the principal amount due (but not the
interest due) in shares of the Company's Common Stock (as defined in Section 6)
calculated based upon the Conversion Price (as defined below). The Company shall
provide the Holder written notice of its intention to pay amounts hereunder in
cash or shares not less than five (5) Trading Days (as defined in Section 6)
prior to the Maturity Date. Except as otherwise provided herein, if at any time
the Company pays less than the total amount of interest then accrued on account
of the Note, such payment shall be distributed ratably among the Holders, if
there is more than one Holder, based upon the aggregate principal amount of
Notes held by each Holder. If the Company pays this Note wholly or partially in
cash and not by issuing shares, in addition to all accrued and unpaid interest
and other charges due hereunder, the Company shall pay a premium of 15% of the
principal amount of this Note which is paid in cash.

         Notwithstanding anything to the contrary contained herein, the Company
may not prepay any portion of this Note by issuing shares of its Common Stock
unless (i) upon issuance such shares will be legally and validly issued,
fully-paid, and non-assessable; and (ii) such shares are registered for resale
pursuant to an effective Registration Statement (as defined in Section 6) and
(iii) such shares are listed or quoted for trading on an "Authorized Market" (as
defined in Section 6). Notwithstanding anything to the contrary contained
herein, the Company may not prepay any portion of this Note by issuing shares of
its Common Stock if the issuance of such shares would result in a violation of
Section 4(a)(ii).

         This Note is subject to the following additional provisions:

         Section 1. The Notes are issuable in denominations of Five Thousand
Dollars ($5,000.00). The Notes are exchangeable for an equal aggregate principal
amount of Notes of different authorized denominations, as requested by the
Holder surrendering the same but shall not be issuable in denominations of less
than integral multiples of Five Thousand Dollars ($5,000) unless such amount
represents the full principal balance of Notes outstanding to such Holder. No
service charge will be made for such registration of transfer or exchange.

         Section 2.

                  (a) This Note may not be sold, transferred, assigned,
hypothecated or divided into two or more Notes of smaller denominations, nor may
any Underlying Shares be transferred, sold, assigned or hypothecated except in
accordance with this Section. The Holder, by acceptance hereof, agrees to give
written notice to the Company before transferring this Note or transferring any
Underlying Shares; such notice will describe briefly the any proposed transfer
and will give the Company the name, address, and tax identification number of
the proposed transferee, and will further provide the Company with an opinion of
the Holder's counsel that such transfer can be accomplished in accordance with
federal and applicable state securities laws (unless such transaction is
permitted by the plan of distribution in an effective Registration Statement).
Promptly upon receiving such written notice, the Company shall present copies
thereof to the Company's counsel.

                                       2
<PAGE>

         (i) If in the opinion of such counsel the proposed transfer may be
         effected without registration or qualification (under any federal or
         state securities laws), the Company, as promptly as practicable, shall
         notify the Holder of such opinion, whereupon the Holder shall be
         entitled to transfer this Note or to dispose of Underlying Shares
         received upon the previous conversion of this Note, all in accordance
         with the terms of the notice delivered by the Holder to the Company;
         provided that an appropriate legend may be endorsed on this Note or the
         certificates for such Underlying Shares respecting restrictions upon
         transfer thereof necessary or advisable in the opinion of counsel and
         satisfactory to the Company to prevent further transfers which would be
         in violation of Section 5 of the Securities Act and applicable state
         securities laws; and provided further that the prospective transferee
         or purchaser shall execute such documents and make such
         representations, warranties, and agreements as may be required solely
         to comply with the exemptions relied upon by the Company for the
         transfer or disposition of the Note or Underlying Shares.

         (ii) If in the opinion of the counsel referred to in this Section 2,
         the proposed transfer or disposition of this Note or such Underlying
         Shares described in the written notice given pursuant to this Section 2
         may not be effected without registration or qualification of this Note
         or such Underlying Shares the Company shall promptly give written
         notice thereof to the Holder, and the Holder will limit its activities
         in respect to such as, in the opinion of such counsel, are permitted by
         law provided further that if a Registration Statement with regard to
         the Underlying Shares has been substantially prepared for filing the
         Holder shall withdraw or defer any proposed transfer, or agree to a
         modification of the Effective Date pursuant to the Registration Rights
         Agreement (as defined in Section 6).

                  (b) Prior to transfer of this Note in compliance with this
Section 2, the Company and any agent of the Company may treat the person in
whose name this Note is duly registered on the Note Register as the owner hereof
for the purpose of receiving payment as herein provided and for all other
purposes, whether or not this Note is overdue, and neither the Company nor any
such agent shall be affected by notice to the contrary.

         Section 3. Events of Default.

                  "Event of Default" wherever used herein, means any one of the
following events (whatever the reason and whether it shall be voluntary or
involuntary or effected by operation of law or pursuant to any judgment, decree

         Payment Date, Conversion Date or the Maturity Date or by acceleration
         or otherwise);

         breach shall not have been remedied within 10 days after the date on
         which notice of such failure or breach shall have been given, or the

<PAGE>

         public announcement, at any time, of its intention not to comply with
         requests for conversions of any Notes in accordance with the terms
         hereof.

         Section 4. Conversion.

                  (a)      (i) This Note shall be convertible into shares of
         Common Stock (subject to the limitation set forth in Section 4(a)(ii))
         at the option of the Holder in whole or in part at any time and from
         time to time and prior to the close of business on the Maturity Date.
         The number of shares of Common Stock issuable upon a conversion
         hereunder shall be determined by dividing the outstanding principal
         amount of this Note to be converted by the Conversion Price, each as
         subject to adjustment as provided hereunder. The Holder shall effect
         conversions by delivering to the Company a conversion notice in the
         form of conversion notice attached hereto as Exhibit A (the "Conversion
         Notice"), specifying the information on the Conversion Notice form.
         Each Conversion Notice shall specify the principal amount of Notes to
         be converted and the date on which such conversion is to be effected,
         which date may not be prior to the date of such Conversion Notice is
         deemed to have been delivered pursuant to Section 4(h) (the "Conversion
         Date"). If no Conversion Date is specified in a Conversion Notice, the
         Conversion Date shall be the date that the Conversion Notice is deemed
         delivered pursuant to Section 4(h). Subject to Section 4(b) hereof,
         each Conversion Notice, once given, shall be irrevocable. If the Holder
         is converting less than all of the principal amount represented by the
         Note(s) tendered by the Holder with the Conversion Notice, or if a
         conversion hereunder cannot be effected in full for any reason, the
         Company shall honor such conversion and shall promptly deliver to such
         Holder (in the manner and within the time set forth in Section 4(b)) a
         new Note for such principal amount as has not been converted.

                           (ii) Certain Conversion Restrictions. The Holder
         agrees not to convert Notes to the extent such conversion would result
         in the Holder beneficially owning (as determined in accordance with
         Section 13(d) of the Exchange Act and the rules thereunder) in excess
         of 4.999% of the then issued and outstanding shares of Common

                                       5
<PAGE>

         Stock, including shares issuable upon conversion of the Notes held by
         such Holder after application of this Section. The Holder shall have
         the sole authority and obligation to determine whether the restriction
         contained in this Section applies and to the extent the Holder
         determines that the restriction contained in this Section applies, the
         determination of which portion of the principal amount of such Notes is
         convertible shall be in the sole discretion of the Holder. The
         provisions of this Section may be waived by a Holder (but only as to
         itself and not to any other Holder) upon not less than 65 days prior
         notice to the Company. Other Holders shall be unaffected by any such
         waiver.

                  (b)      (i) Not later than three (3) Trading Days after the
         Conversion Date, the Company will deliver to the Holder a Free Trading
         Certificate or certificates free of restrictive legends, trading
         restrictions or stop transfer orders representing the number of shares
         of the Common Stock being acquired upon the conversion of the Note(s),
         and (ii) a corporate check in the amount of all accrued and unpaid
         interest, together with all other amounts then due and payable in
         accordance with the terms hereof, in respect of the Note(s) tendered
         for conversion. The Company shall keep a register and log each
         conversion of the Note(s) by entering the amount of the Note(s)
         converted and the principal balance of the Note(s) once the conversion
         has taken place. There shall be no obligation on the part of the Holder
         to deliver the Notes with each conversion. Upon a final conversion of
         the Notes, or payment by the Company of all amounts due under the
         Notes, as the case may be, the Holder will surrender the original Notes
         to the Company. Nothing stated herein shall preclude the Holder from
         requesting from the Company Notes reflecting the principal balance
         thereunder which shall be provided to the Holder simultaneously upon
         the surrender of any Notes in the Holder's possession. The Company
         shall, upon request of the Holder, use its best efforts to deliver any
         certificate or certificates required to be delivered by the Company
         under this Section electronically through the Depository Trust
         Corporation or another established clearing corporation performing
         similar functions. If in the case of any Conversion Notice such Free
         Trading Certificate or certificates, are not delivered to or as
         directed by the applicable Holder by the third Trading Day after a
         Conversion Date, the Holder shall be entitled by written notice to the
         Company at any time on or before its receipt of such certificate or
         certificates thereafter, to rescind such conversion.

                           (ii) If the Company fails to deliver to the Holder
         such certificate or certificates pursuant to this Section prior to the
         third Trading Day after a Conversion Date, then the Company shall pay
         to the Holder $150 per day for each day late in delivering the
         certificates up to and including the 10th late day, and $500 per day
         for each day late in delivering the Certificates after the 10th late
         day ("Liquidated Damages"). Any Liquidated Damages incurred by the
         Company shall be payable immediately and in cash upon demand in writing
         made by the Holder, or their agent, to the Company.

                           (iii) Intentionally omitted.

                           (iv) In the event a Holder shall elect to convert a
         Note or part thereof, the Company may not refuse conversion based on
         any claim that such Holder or any one

                                       6
<PAGE>

         associated or affiliated with such Holder has been engaged in any
         violation of law, or for any other reason, unless, an injunction from a
         court, or notice, restraining and or enjoining conversion of all or
         part of said Note shall have been sought and obtained and the Company
         posts a surety bond for the benefit of such Holder in the amount of
         130% of the amount of the Note, which is subject to the injunction,
         which bond shall remain in effect until the completion of litigation of
         the dispute and the proceeds of which shall be payable to such Holder
         to the extent Holder obtains judgment.

                  (c)      (i) The conversion price (the "Conversion Price") in
         effect shall be 75% of the Market Price; and the term "Market Price"
         means the Volume Weighted Average Price ("VWAP") as reported by
         Bloomberg Financial Services for the 10 trading days of the Company's
         common stock just prior to the date of the Notice of Conversion. If the
         VWAP is not available through Bloomberg for any reason, then the VWAP
         shall be the average of the bid prices of any market makers for the
         Company's Common Stock as reported on the National Quotations Systems
         Pink Sheets ("Pink Sheets") or as reported by the National Association
         of Securities Dealers Electronic Bulletin Board ("OTC Bulletin Board"),
         wherever such bid prices are available.

                           (ii) If the Company, at any time while any Notes are
         outstanding, (a) shall pay a stock dividend or otherwise make a
         distribution or distributions on shares of its Common Stock or any
         other equity or equity equivalent securities payable in shares of the
         Common Stock, (b) subdivide outstanding shares of the Common Stock into
         a larger number of shares, (c) combine outstanding shares of the Common
         Stock into a smaller number of shares, or (d) issue by reclassification
         of shares of the Common Stock any shares of capital stock of the
         Company, the Initial Conversion Price shall be multiplied by a fraction
         of which the numerator shall be the number of shares of the Common
         Stock (excluding treasury shares, if any) outstanding before such event
         and of which the denominator shall be the number of shares of the
         Common Stock outstanding after such event. Any adjustment made pursuant
         to this Section 4(c)(ii) shall become effective immediately after the
         record date for the determination of stockholders entitled to receive
         such dividend or distribution and shall become effective immediately
         after the effective date in the case of a subdivision, combination or
         re-classification.

                           (iii) If the Company, at any time while any Notes are
         outstanding, shall issue rights or warrants to all holders of the
         Common Stock (and not to Holders of Notes) entitling them to subscribe
         for or purchase shares of the Common Stock at a price per share less
         than the Conversion Price, the Conversion Price shall be multiplied by
         a fraction, of which

         the denominator shall be the number of shares of the Common Stock
         (excluding treasury shares, if any) outstanding on the date of issuance
         of such rights or warrants plus the number of additional shares of the
         Common Stock offered for subscription or purchase, and

         the numerator shall be the number of shares of the Common Stock
         (excluding treasury shares, if any) outstanding on the date of issuance
         of such rights or warrants plus the

                                       7
<PAGE>

         number of shares which the aggregate offering price of the total number
         of shares so offered would purchase at the Conversion Price.

Such adjustment shall be made whenever such rights or warrants are issued, and
shall become effective immediately after the record date for the determination
of stockholders entitled to receive such rights or warrants. However, upon the
expiration of any right or warrant to purchase shares of the Common Stock the
issuance of which resulted in an adjustment in the Conversion Price pursuant to
this Section 4(c)(iii), if any such right or warrant shall expire and shall not
have been exercised, the Conversion Price shall immediately upon such expiration
be recomputed and effective immediately upon such expiration be increased to the
price which it would have been (but reflecting any other adjustments in the
Conversion Price made pursuant to the provisions of this Section 4 after the
issuance of such rights or warrants) had the adjustment of the Conversion Price
made upon the issuance of such rights or warrants been made on the basis of
offering for subscription or purchase only that number of shares of the Common
Stock actually purchased upon the exercise of such rights or warrants actually
exercised.

                  (iv) If the Company, as applicable with respect to Common
Stock Equivalents (as defined below), at any time while this Note is
outstanding, shall issue shares of Common Stock or rights, warrants, options or
other securities or debt that is convertible into or exchangeable for shares of
Common Stock ("Common Stock Equivalents") entitling any Person to acquire shares
of Common Stock at a price per share less than the Conversion Price, then the
Conversion Price shall be multiplied by a fraction,

         the numerator of which shall be the number of shares of Common Stock
         outstanding immediately prior to the issuance of shares of Common Stock
         or such Common Stock Equivalents plus the number of shares of Common
         Stock which the offering price for such shares of Common Stock or
         Common Stock Equivalents would purchase at the Conversion Price, and

         the denominator of which shall be the sum of the number of shares of
         Common Stock outstanding immediately prior to such issuance plus the
         number of shares of Common Stock so issued or issuable,

provided, that for purposes hereof, all shares of Common Stock that are issuable
upon exercise or exchange of Common Stock Equivalents shall be deemed
outstanding immediately after the issuance of such Common Stock Equivalents.
Such adjustment shall be made whenever such shares of Common Stock or Common
Stock Equivalents are issued but shall be issued to the Holder on the same basis
as the other holders of Common Stock or Common Stock Equivalents.

                  (v) If the Company, at any time while Notes are outstanding,
shall distribute to all holders of the Common Stock (and not to Holders of
Notes) evidences of its indebtedness or assets or rights or warrants to
subscribe for or purchase any security, then in each such case the Initial
Conversion Price at which the Note(s) shall thereafter be convertible shall be
determined by multiplying the Initial Conversion Price in effect immediately
prior to the record date fixed for determination of stockholders entitled to
receive such distribution by a fraction of which

                                       8
<PAGE>

         the denominator shall be the Per Share Market Value of the Common Stock
         determined as of the record date mentioned above, and

         the numerator shall be such Per Share Market Value of the Common Stock
         on such record date less the then fair market value at such record date
         of the portion of such assets or evidence of indebtedness so
         distributed applicable to one outstanding share of the Common Stock as
         determined by the Board of Directors in good faith; provided, however,
         that in the event of a distribution exceeding ten percent (10%) of the
         net assets of the Company, such fair market value shall be determined
         by a nationally recognized or major regional investment banking firm or
         firm of independent certified public accountants of recognized standing
         (which may be the firm that regularly examines the financial statements
         of the Company) (an "Appraiser") selected in good faith by the holders
         of a majority in interest of Notes then outstanding; and provided,
         further, that the Company, after receipt of the determination by such
         Appraiser shall have the right to select an additional Appraiser, in
         good faith, in which case the fair market value shall be equal to the
         average of the determinations by each such Appraiser.

In either case the adjustments shall be described in a statement provided to the
holders of Notes of the portion of assets or evidences of indebtedness so
distributed or such subscription rights applicable to one share of the Common
Stock. Such adjustment shall be made whenever any such distribution is made and
shall become effective immediately after the record date mentioned above.

                  (vi) In case of any reclassification of the Common Stock or
any compulsory share exchange pursuant to which the Common Stock is converted
into other securities, cash or property, the Holder of this Note shall have the
right thereafter to, at its option, convert the then outstanding principal
amount only into the shares of stock and other securities, cash and property
receivable upon or deemed to be held by holders of the Common Stock following
such reclassification or share exchange, and the Holders of the Notes shall be
entitled upon such event to receive such amount of securities, cash or property
as the shares of the Common Stock of the Company into which the then outstanding
principal amount could have been converted immediately prior to such
reclassification or share exchange would have been entitled. The terms of any
such reclassification or share exchange shall include such terms so as to
continue to give to the Holder the right to receive the securities, cash or
property set forth in this Section 4(c)(vi) upon any conversion following such
event. This provision shall similarly apply to successive reclassifications or
share exchanges.

                  (vii) If:

                           A. the Company shall declare a dividend (or any other
         distribution) on its Common Stock; or

                           B. the Company shall declare a special nonrecurring
         cash dividend on or a redemption of its Common Stock; or

                                       9
<PAGE>

                           C. the Company shall authorize the granting to all
         holders of the Common Stock rights or warrants to subscribe for or
         purchase any shares of capital stock of any class or of any rights; or

                           D. the approval of any stockholders of the Company
         shall be required in connection with any reclassification of the Common
         Stock of the Company, any consolidation or merger to which the Company
         is a party, any sale or transfer of all or substantially all of the
         assets of the Company, of any compulsory share of exchange whereby the
         Common Stock is converted into other securities, cash or property; or

                           E. the Company shall authorize the voluntary or
         involuntary dissolution, liquidation or winding up of the affairs of
         the Company;

then the Company shall cause to be filed at each office or agency maintained for
the purpose of conversion of the Notes, and shall cause to be mailed to the
Holders of Notes at their last addresses as they shall appear upon the stock
books of the Company, at least 30 calendar days prior to the applicable record
or effective date hereinafter specified, a notice stating (x) the date on which
a record is to be taken for the purpose of such dividend, distribution,
redemption, rights or warrants, or if a record is not to be taken, the date as
of which the holders of the Common Stock of record to be entitled to such
dividend, distributions, redemption, rights or warrants are to be determined or
(y) the date on which such reclassification, consolidation, merger, sale,
transfer or share exchange is expected to become effective or close, and the
date as of which it is expected that holders of the Common Stock of record shall
be entitled to exchange their shares of the Common Stock for securities, cash or
other property deliverable upon such reclassification, consolidation, merger,
sale, transfer or share exchange; provided, however, that the failure to mail
such notice or any defect therein or in the mailing thereof shall not affect the
validity of the corporate action required to be specified in such notice.
Holders are entitled to convert Notes during the 30-day period commencing the
date of such notice to the effective date of the event triggering such notice.

                  (viii) All calculations under this Section 4 shall be made to
the nearest cent or the nearest 1/100th of a share, as the case may be.

                  (ix) Whenever the Conversion Price is adjusted pursuant to
Section 4(c)(i) - (v), the Company shall promptly mail to each Holder of Notes,
a notice setting forth the Initial Conversion Price after such adjustment and
setting forth a brief statement of the facts requiring such adjustment.

                  (x) Notwithstanding anything to the contrary herein, in no
event shall the Conversion Price be adjusted for (i) issuances of shares upon
exercise of any warrants, options or convertible securities outstanding as of
the date hereof; (ii) issuances of shares upon conversion of any Notes; (iii)
issuances of options (or shares upon the exercise thereof), stock bonuses, or
shares pursuant to the Company's employee stock incentive plan, and (iv)
issuances of shares in a private placement of the Company's common stock which
is not offered to all shareholders and

                                       10
<PAGE>

not subject to registration rights prior to the Maturity Date of this Note.

                  (d) If at any time conditions shall arise by reason of action
         taken by the Company which in the opinion of the Board of Directors are
         not adequately covered by the other provisions hereof and which might
         materially and adversely affect the rights of the Holders (different
         than or distinguished from the effect generally on rights of holders of
         any class of the Company's capital stock) or if at any time any such
         conditions are expected to arise by reason of any action contemplated
         by the Company, the Company shall mail a written notice briefly
         describing the action contemplated and the material adverse effects of
         such action on the rights of the Holders at least 30 calendar days
         prior to the effective date of such action, and an Appraiser selected
         by the Holders of majority in interest of the Notes shall give its
         opinion as to the adjustment, if any (not inconsistent with the
         standards established in this Section 4), of the Conversion Price
         (including, if necessary, any adjustment as to the securities into
         which Notes may thereafter be convertible) and any distribution which
         is or would be required to preserve without diluting the rights of the
         Holders; provided, however, that the Company, after receipt of the
         determination by such Appraiser, shall have the right to select an
         additional Appraiser, in good faith, in which case the adjustment shall
         be equal to the average of the adjustments recommended by each such
         Appraiser. The Board of Directors shall make the adjustment recommended
         forthwith upon the receipt of such opinion or opinions or the taking of
         any such action contemplated, as the case may be; provided, however,
         that no such adjustment of the Conversion Price shall be made which in
         the opinion of the Appraiser(s) giving the aforesaid opinion or
         opinions would result in an increase of the Conversion Price to more
         than the Conversion Price then in effect.

                  (e) The Company covenants that it will at all times reserve
         and keep available out of its authorized and unissued shares of the
         Common Stock solely for the purpose of issuance upon conversion of the
         Notes and payment of interest on the Notes, each as herein provided,
         free from preemptive rights or any other actual contingent purchase
         rights of persons other than the Holders, not less than such number of
         shares of the Common Stock as shall (subject to any additional
         requirements of the Company as to reservation of such shares set forth
         in the Financing Agreement) be issuable (taking into account the
         adjustments and restrictions of Section 4(c)) upon the conversion of
         the outstanding principal amount of the Notes and payment of interest
         hereunder. The Company covenants that all shares of the Common Stock
         that shall be so issuable shall, upon issue, be duly and validly
         authorized, issued and fully paid, nonassessable and, if the
         Registration Statement has been declared effective under the Securities
         Act, freely tradeable.

                  (f) Upon a conversion hereunder the Company shall not be
         required to issue stock certificates representing fractions of shares
         of the Common Stock, but may if otherwise permitted, make a cash
         payment in respect of any final fraction of a share based on the Per
         Share Market Value at such time. If the Company elects not, or is
         unable, to make such a cash payment, the holder shall be entitled to
         receive, in lieu of the final fraction of a share, one whole share of
         Common Stock.

                                       11

                  (g) The issuance of certificates for shares of the Common
         Stock on conversion of the Notes shall be made without charge to the
         Holders thereof for any documentary stamp or similar taxes that may be
         payable in respect of the issue or delivery of such certificate,
         provided that the Company shall not be required to pay any tax that may
         be payable in respect of any transfer involved in the issuance and
         delivery of any such certificate upon conversion in a name other than
         that of the Holder of such Notes so converted and the Company shall not
         be required to issue or deliver such certificates unless or until the
         person or persons requesting the issuance thereof shall have paid to
         the Company the amount of such tax or shall have established to the
         satisfaction of the Company that such tax has been paid.

                  (h) Any and all notices or other communications or deliveries
         to be provided by the Holders of the Notes hereunder, including,

         delivered personally, by facsimile, sent by a nationally recognized

         facsimile telephone number or address of such Holder appearing on the

         notice or other communication or deliveries hereunder shall be deemed
         given and effective on the earliest of (i) the date of transmission, if
         such notice or communication is delivered via facsimile at the
         facsimile telephone number specified in this Section prior to 5:00 p.m.

         Section 5. Prepayment.

                  (a) The Company shall have the right to prepay up to fifty
         (50%) of the principal balance of this Note and all accrued but unpaid
         interest thereon prior to the Maturity Date in cash provided that the
         Company shall pay the Holder a premium of 15% of the principal balance
         prepaid, along with any and all accrued interest and other charges due
         under this Note. The Company shall have the right to prepay up to one
         hundred (100%) of the principal balance of this Note and all accrued
         but unpaid interest thereon prior to the Maturity Date in cash provided
         that (i) the Company shall pay the Holder a

                                       12

         premium of 15% of the principal balance prepaid, along with any and all
         accrued interest and other charges due under this Note and (ii) the
         Underlying Shares of Common Stock issuable upon conversion of this Note
         (x) are registered for resale pursuant to an effective Registration

         which notice shall specify the "Prepayment Date".

                           (ii) With respect to any Note for which a Notice of
         Conversion is submitted to the Company prior to the Prepayment Date,
         the Notice of Conversion shall take precedence and such Note shall be
         converted in accordance with the terms hereof. Furthermore, in the
         event such prepayment is not timely made, the Notice of Prepayment
         shall be null and void, and any rights of the Company to thereafter
         prepay this Note shall be subject to the deposit of the amount to be
         paid in escrow, with an attorney designated by the Holder, not later
         than two business days after delivery of any Notice.

such proceeding in such jurisdictions. To the extent determined by such court,
the Company shall reimburse the Holder for any reasonable legal fees and

2.       PURCHASE AND SALE OF COMMON STOCK.

         a. Purchase and Sale of Common Stock. Upon the terms and conditions set
forth herein, the Company shall issue and sell to the Investor, and the Investor
shall purchase from the Company, up to that number of Shares having an aggregate
Purchase Price of $1,000,000.

         b. Delivery of Preliminary Put Notices and Put Notices. Subject to the
terms and conditions of the Transaction Documents, and from time to time during
the Open Period the Company may, in its sole discretion, deliver a Preliminary
Put Notice to the Investor which states the Put Amount of Shares which the
Company intends to sell to the Investor during the Pricing Period, the relevant
Pricing Period and the Floor Price. On the next Trading Day following the
Pricing Period, the Company shall delivery a Put Notice to the Investor which
states the Purchase Price of the Shares to be sold and the total number of
Shares to be sold based on the Purchase Price and the Put Amount. Once the Put
Notice is received by the Investor and provided the Purchase Price is greater
than the Floor Price by any amount the Put Notice shall not be terminated and
shall be irrevocable. If the Purchase Price is equal to or less than the Floor
Price, the Put Notice shall be void and no sale of Shares shall take place
During the Open Period, the Company shall not be entitled to submit a Put Notice
until after the previous closing has taken place, and in any event no more than
one Put Notice may be given by the Company during a thirty (30) day period

quarter occurring subsequent to the commencement of the Open Period, the Company
undertakes to notify Investor as to its reasonable expectations as to the Put
Amount it intends to raise during such calendar

<PAGE>

quarter, if any, through the issuance of Put Notices. Such notification shall

quarter and shall in no way obligate the Company to raise such amount during
such calendar quarter or otherwise limit its ability to deliver Put Notices
during such calendar quarter.

         c. Interest. It is the intention of the parties that only interest that
may be payable under this Agreement shall not exceed the maximum amount
permitted under any applicable law. If a law, which applies to this Agreement
which sets the maximum interest amount, is finally interpreted so that the
interest in connection with this Agreement exceeds the permitted limits, then:
(1) any such interest shall be reduced by the amount necessary to reduce the
interest to the permitted limit; and (2) any sums already collected (if any)
from the Company which exceed the permitted limits will be refunded to the
Company. The Investor may choose to make this refund by reducing the amount that
the Company owes under this Agreement or by making a direct payment to the
Company. If a refund reduces the amount that the Company owes the Investor, the
reduction will be treated as a partial payment. In case any provision of this
Agreement is held by a court of competent jurisdiction to be excessive in scope
or otherwise invalid or unenforceable, such provision shall be adjusted rather
than voided, if possible, so that it is enforceable to the maximum extent
possible, and the validity and enforceability of the remaining provisions of
this Agreement will not in any way be affected or impaired thereby.

         d. Investor's Obligation to Purchase Shares. Subject to the conditions
set forth in this Agreement, following the Investor's receipt of a validly
delivered Put Notice, the Investor shall be required to purchase from the
Company during the related Pricing Period the Put Amount of Shares which the
Company intends to sell set forth in the Put Notice, but only if said Shares
bear no restrictive legend, are not subject to stop transfer instructions and
are being held in escrow, pursuant to Section 2(h), prior to the applicable
Closing Date.

         e. Limitation on Investor's Obligation to Purchase Shares.
Notwithstanding anything to the contrary in this Agreement, in no event shall
the Investor be required to purchase, and the Company shall in no event sell to
the Investor, that number of Shares, which when added to the sum of the number
of Shares beneficially owned, (as such term is defined under Section 13(d) and
Rule 13d-3 of the Securities Exchange Act of 1934, as may be amended, (the "1934
Act")), by the Investor, would exceed four and ninety-nine hundredths percent
(4.99%) of the number of Shares outstanding on the Put Notice Date for such
Pricing Period, as determined in accordance with Rule 13d-1(j) under the 1934
Act. In no event shall the Investor purchase Shares of the Common Stock other
than pursuant to this Agreement until such date as this Agreement is terminated.
Each Put Notice shall include a representation of the Company as to the number
of Shares of Common Stock outstanding on the related Put Notice Date as
determined in accordance with Section 13(d) of the 1934 Act. In the event that
the number of Shares of Common Stock outstanding as determined in accordance
with Section 13(d) of the 1934 Act is different on any date during a Pricing
Period than on the Put Notice Date associated with such Pricing Period, then the
number of Shares of Common Stock outstanding on such date during such Pricing
Period shall govern for purposes of determining whether the Investor would be
acquiring beneficial ownership of more than four and ninety-nine hundredths
percent (4.99%) of the number of Shares of Common Stock outstanding during such
period.

<PAGE>

         f. Conditions to Investor's Obligation to Purchase Shares.

                  Period;

                  (ii) at all times during the period beginning on the related

                  the Principal Market (daily trading volume excluding all block
                  trades x closing bid price) shall be at least twenty-five
                  thousand dollars ($25,000) and the average of the closing bid
                  price for such twenty (20) day period shall be greater than
                  two dollars and fifty cents ($2.50) per share;

                  (iv) the Company has complied with its obligations and is

                  (v) no injunction shall have been issued, or action commenced

                  (vi) the issuance of the Common Stock will not violate the

                  If any of the events described in clauses (i) through (v)
                  above occurs during a Pricing Period, then the Investor shall
                  have no obligation to purchase the Put Amount of Common Stock
                  set forth in the applicable Put Notice.

           g. For purposes of this Agreement, a "Major Transaction" shall be
deemed to have occurred at the closing of any of the following events: (i) the

Prior to each Closing Date, (i) the Company shall deliver to the Escrow Agent
pursuant to the Escrow Agreement certificates representing the Shares to be
issued to the Investor on such date and registered in the name of the Investor
or deposit such Shares into the account(s) (with the Investor receiving

for the benefit of the Investor and (ii) the Investor shall deliver to the
Escrow Agent the Purchase Price to be paid for such Shares (after receipt of

transfer. In lieu of delivering physical certificates representing the Common
Stock and provided that the Transfer Agent then is participating in The
Depository Trust Company ("DTC") Fast Automated Securities Transfer ("FAST")
program, upon request of the Investor, the Company shall use its commercially
reasonable efforts to cause the Transfer Agent to electronically transmit the
shares of Common Stock by crediting the account of the Investor's prime broker
(which shall be specified by Investor a reasonably sufficient time in advance)
with DTC through its Deposit Withdrawal Agent Commission ("DWAC") system, and
provide proof satisfactory to the Escrow Agent of such delivery.

         i. Reserved.

         j. Overall Limit on Common Stock Issuable. Notwithstanding anything
contained herein to the contrary, if during the Open Period the Company becomes
listed on an exchange that limits the number of shares of Common Stock that may
be issued without shareholder approval, then the number of Shares issuable by
the Company and purchasable by the Investor, including the shares of Common
Stock issuable to the Investor pursuant to Section 11(b), shall not exceed that
number of the shares of Common Stock that may be issuable without shareholder
approval, subject to appropriate adjustment for stock splits, stock dividends,
combinations or other similar recapitalization affecting the Common Stock
("Maximum Common Stock Issuance"), unless the issuance of Shares, including any
Common Stock to be issued to the Investor pursuant to Section 11(b), in excess
of the Maximum Common Stock Issuance shall first be approved by the Company's
shareholders in accordance with applicable law and the By-laws and Articles of
Incorporation of the Company, if such issuance of shares of Common Stock could
cause a delisting on the Principal Market. The parties understand and agree that
the Company's failure to seek or obtain such shareholder approval shall in no
way adversely affect the validity and due authorization of the issuance and sale
of Shares hereunder or the Investor's obligation in accordance with the terms
and conditions hereof to purchase a number of Shares in the aggregate up to the
Maximum Common Stock Issuance limitation, and that such approval

<PAGE>

pertains only to the applicability of the Maximum Common Stock Issuance

time during a "Pricing Period" takes any of the following actions:

                  (ii) pays a dividend in Common Stock or makes any other

                  (iii) issues any options or other rights to subscribe for or
                  purchase Common Stock and the price per share for which Common
                  Stock may at any time thereafter be issuable pursuant to such
                  options or other rights shall be less than the bid price in
                  effect immediately prior to such issuance;

                  (iv) issues any securities convertible into or exchangeable
                  for Common Stock and the consideration per share for which
                  shares of Common Stock may at any time thereafter be issuable
                  pursuant to the terms of such convertible or exchangeable
                  securities shall be less than the bid price in effect
                  immediately prior to such issuance;

                  (v) issues shares of Common Stock otherwise than as provided
                  in the foregoing subsections (i) through (iv), at a price per
                  share less, or for other consideration lower, than the bid
                  price in effect immediately prior to such issuance, or without
                  consideration;

                  (vi) makes a distribution of its assets or evidences of
                  indebtedness to the holders of Common Stock as a dividend in
                  liquidation or by way of return of capital or other than as a
                  dividend payable out of earnings or surplus legally available
                  for dividends under applicable law or any distribution to such
                  holders made in respect of the sale of all or substantially
                  all of the Company's assets (other than under the
                  circumstances provided for in the foregoing subsections (i)
                  through (v); or

                  (vii) takes any action affecting the number of shares of
                  Common Stock outstanding, other than an action described in
                  any of the foregoing subsections (i) through (vi) hereof,
                  inclusive, which in the opinion of the Company's Board of
                  Directors, determined in good faith, would have a materially
                  adverse effect upon the rights of Investor at the time of a
                  Put Notice is delivered to Investor.

         l. The Company agrees that it shall not take any action that would
result in a Valuation Event occurring during a Pricing Period.

         m. Accountant's Letter and Registration Opinion. Whenever reasonably
requested by Investor, the Company shall cause to be delivered to the Investor,
on or prior to each Registration Opinion Deadline, an opinion of the Company's
independent counsel, ("Registration Opinion"),

<PAGE>

addressed to the Investor stating, inter alia, that no facts ("Material Facts")
have come to such counsel's attention that have caused it to believe that the
Registration Statement is subject to an Ineffective Period or to believe that
the Registration Statement, any supplemental Registration Statement (as each may
be amended, if applicable), and any related prospectuses, contain an untrue
statement of material fact or omits a material fact required to make the
statements contained therein, in light of the circumstances under which they
were made, not misleading. If a Registration Opinion cannot be delivered by the
Company's independent counsel to the Investor on the Registration Opinion
Deadline due to the existence of Material Facts or an Ineffective Period, the
Company shall promptly notify the Investor and as promptly as possible amend
each of the Registration Statement and any supplemental Registration Statements,
as applicable, and any related prospectus or cause such Ineffective Period to
terminate, as the case may be, and deliver such Registration Opinion and updated
prospectus as soon as possible thereafter. If at any time after a Put Notice
shall have been delivered to Investor but before the related Closing Date, the
Company acquires knowledge of such Material Facts or any Ineffective Period
occurs, the Company shall promptly notify the Investor.

         n. (i) Whenever reasonably requested by Investor (at the expense of the
            Company on one occasion and at the expense of the Investor on any
            other occasion), the Company shall engage its independent auditors
            to perform the procedures in accordance with the provisions of
            Statement on Auditing Standards No. 71, as amended, as agreed to by
            the parties hereto, and reports thereon ("Bring Down Cold Comfort
            Letters") as shall have been reasonably requested by the Investor
            with respect to certain financial information contained in the
            Registration Statement and shall have delivered to the Investor such
            a report addressed to the Investor, on or prior to each Registration
            Opinion Deadline;

            (ii) in the event that the Investor shall have requested delivery of
            an Agreed Upon Procedures Report pursuant to Section 2(o), the
            Company shall engage its independent auditors to perform certain
            agreed upon procedures and report thereon as shall have been
            reasonably requested by the Investor with respect to certain
            financial information of the Company and the Company shall deliver
            to the Investor a copy of such report addressed to the Investor. In
            the event that the report required by this Section 2(n) cannot be
            delivered by the Company's independent auditors, the Company shall,
            if necessary, promptly revise the Registration Statement and the
            Company shall not deliver a Put Notice to Investor until such report
            is delivered.

         o. Procedure if Material Facts are Reasonably believed to be untrue or
are omitted. In the event after such consultation the Investor or the Investor's
counsel reasonably believes that the Registration Statement contains an untrue
statement or a material fact or omits a material fact required to be stated in
the Registration Statement or necessary to make the statements contained
therein, in light of the circumstances in which they were made, not misleading,
(i) the Company shall file with the SEC an amendment to the Registration
Statement responsive to such alleged untrue statement or omission and provide
the Investor, as promptly as practicable, with copies of the Registration
Statement and related Prospectus, as so amended, or (ii) if the Company disputes
the existence of any such material misstatement or omission, (x) the Company's
independent counsel shall provide the Investor's counsel with a Registration
Opinion and (y) in the event the

<PAGE>

dispute relates to the adequacy of financial disclosure and the Investor shall
reasonably request, the Company's independent auditors shall provide to the
Company a letter ("Agreed Upon Procedures Report") outlining the performance of
such "agreed upon procedures" as shall be reasonably requested by the Investor
and the Company shall provide the Investor with a copy of such letter.

         p. Delisting; Suspension. If at any time during the Open Period or
within thirty (30) calendar days after any purchase of Shares by the Investor,
(i) the Registration Statement, after it has been declared effective, shall not
remain effective and available for sale of all the Registrable Securities, (ii)
the Common Stock shall not be listed on the Principal Market or shall have been
suspended from trading thereon (excluding suspensions of not more than one
trading day resulting from business announcements by the Company) or the Company
shall have been notified of any pending or threatened proceeding or other action
to delist or suspend the Common Stock, (iii) there shall have occurred a Major
Transaction (as defined in Section 2(g)) or the public announcement of a pending
Major Transaction which has not been abandoned or terminated, or (iv) the
Registration Statement is no longer effective or stale for a period of more than
five (5) Trading Days as a result of the Company to timely file its financials,
the Company shall repurchase within thirty (30) calendar days of the occurrence
of one of the events listed in clauses (i), (ii), (iii) or (iv)above (each a
"Repurchase Event") and subject to the limitations imposed by applicable federal
and state law, all or any part of the Shares issued to the Investor within the
sixty (60) Trading Days preceding the occurrence of the Repurchase Event and
then held by the Investor at a price per Share equal to the highest Volume
Weighted Average Price during the period beginning on the date of the Repurchase
Event and ending on and including the date on which the Investor is paid by the
Company for the repurchase of the Shares but not more than the Purchase Price
paid by the Investor for the Shares ("Payment Amount"). If the Company fails to
pay to the Investor the full aggregate Payment Amount within ten (10) calendar
days of the occurrence of a Repurchase Event, the Company shall pay to the
Investor, on the first Trading Day following such tenth (10th) calendar day, in
addition to and not in lieu of the Payment Amount payable by the Company to the
Investor an amount equal to two percent (2%) of the aggregate Payment Amount
then due and payable to the Investor, in cash by wire transfer, plus compounded
annual interest of eighteen percent (18%) on such Payment Amount during the
period, beginning on the day following such tenth calendar day, during which
such Payment Amount, or any portion thereof, is outstanding.

<PAGE>

reorganization, moratorium, liquidation and other similar laws relating to, or
affecting generally, the enforcement of applicable creditors' rights and
remedies..

         c. Section 9 of the 1934 Act. During the Open Period, the Investor will
comply with the provisions of Section 9 of the 1934 Act, and the rules
promulgated thereunder, with respect to transactions involving the Common Stock.

         d. Accredited Investor. Investor is an "Accredited Investor" as that
term is defined in Rule 501(a)(3) of Regulation D of the 1933 Act.

         e. No Conflicts. The execution, delivery and performance of the
Transaction Documents by the Investor and the consummation by the Investor of
the transactions contemplated hereby and thereby will not (i) result in a
violation of the Articles of Incorporation or the By-laws or (ii) conflict with,
or constitute a material default (or an event which with notice or lapse of time
or both would become a material default) under, or give to others any rights of
termination, amendment, acceleration or cancellation of, any material agreement,
contract, indenture mortgage, indebtedness or instrument to which the Investor
or any of its Subsidiaries is a party, or result in a violation of any law,
rule, regulation, order, judgment or decree applicable to the Investor or any of
its Subsidiaries or by which any property or asset of the Investor or any of its
Subsidiaries is bound or affected. The business of the Investor and its
Subsidiaries is not being conducted, and shall not be conducted, in violation of
any law, statute, ordinance, rule, order or regulation of any governmental
authority or agency, regulatory or self-regulatory agency, or court, except for
possible violations the sanctions for which either individually or in the

4.       REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         Except as set forth in the Schedules attached hereto, the Company
represents and warrants to the Investor that:

         a. Organization and Qualification. The Company and its "Subsidiaries"
(which for purposes of this Agreement means any entity in which the Company,
directly or indirectly, owns capital stock or holds an equity or similar
interest) are corporations duly organized and validly existing in good standing
under the laws of the respective jurisdictions of their incorporation, and have
the requisite corporate power and authorization to own their properties and to
carry on their business as now being conducted. Each of the Company and its
Subsidiaries is duly qualified as a foreign corporation to do business and is in
good standing in every jurisdiction in which its

<PAGE>

ownership of property or the nature of the business conducted by it makes such
qualification necessary, except to the extent that the failure to be so
qualified or be in good standing would not have a Material Adverse Effect. As
used in this Agreement, "Material Adverse Effect" means any material adverse
effect on the business, properties, assets, operations, results of operations,
financial condition or prospects of the Company and its Subsidiaries, if any,
taken as a whole, or on the transactions contemplated hereby or by the
agreements and instruments to be entered into in connection herewith, or on the

hereof and thereof, (ii) the execution and delivery of the Transaction Documents
by the Company and the consummation by it of the transactions contemplated
hereby and thereby, including without limitation the reservation for issuance
and the issuance of the Shares pursuant to this Agreement, have been duly and
validly authorized by the Company's Board of Directors and no further consent or
authorization is required by the Company, its Board of Directors, or its
shareholders, (iii) the Transaction Documents have been duly and validly
executed and delivered by the Company, and (iv) the Transaction Documents
constitute the valid and binding obligations of the Company enforceable against
the Company in accordance with their terms, except as such enforceability may be
limited by general principles of equity or applicable bankruptcy, insolvency,
reorganization, moratorium, liquidation or similar laws relating to, or
affecting generally, the enforcement of creditors' rights and remedies.

         c. Capitalization. The authorized capital stock of the Company consists
of (i) ninety-five million (95,000,000) shares of Common Stock, of which
approximately seventeen million five hundred thousand (17,500,000) shares are
issued and outstanding as of May 1, 2003, (ii) five million (5,000,000) shares
of blank check Preferred Stock and no (0) shares of Preferred Stock issued and

shares of Common Stock are issuable upon the exercise of options, warrants and
conversion rights. All of such outstanding shares have been, or upon issuance
will be, validly issued and are fully paid and nonassessable. Except as
disclosed in Schedule 4(c) or as set forth in the SEC Documents, as defined in
Section 4(f) below, which is attached hereto and made a part hereof, (i) no
shares of the Company's capital stock are subject to preemptive rights or any
other similar rights or any liens or encumbrances suffered or permitted by the
Company, (ii) there are no outstanding debt securities, (iii) there are no
outstanding shares of capital stock, options, warrants, scrip, rights to
subscribe to, calls or commitments of any character whatsoever relating to, or
securities or rights convertible into, any shares of capital stock of the
Company or any of its Subsidiaries, or contracts, commitments, understandings or
arrangements by which the Company or any of its Subsidiaries is or may become
bound to issue additional shares of capital stock of the Company or any of its
Subsidiaries or options, warrants, scrip, rights to subscribe to, calls or
commitments of any character whatsoever relating to, or securities or rights
convertible into, any shares of capital stock of the Company or any of its
Subsidiaries, (iv) there are no agreements or arrangements under which the
Company or any of its Subsidiaries is obligated to

<PAGE>

register the sale of any of their securities under the 1933 Act (except the
Registration Rights Agreement), (v) there are no outstanding securities of the
Company or any of its Subsidiaries which contain any redemption or similar
provisions, and there are no contracts, commitments, understandings or
arrangements by which the Company or any of its Subsidiaries is or may become
bound to redeem a security of the Company or any of its Subsidiaries, (vi) there
are no securities or instruments containing anti-dilution or similar provisions
that will be triggered by the issuance of the Securities as described in this
Agreement, (vii) the Company does not have any stock appreciation rights or

through EDGAR to, true and correct copies of the Company's Articles of
Incorporation, as in effect on the date hereof (the "Articles Of
Incorporation"), and the Company's By-laws, as in effect on the date hereof (the
"By-Laws"), and the terms of all securities convertible into or exercisable for
Common Stock and the material rights of the holders thereof in respect thereto.

         d. Issuance of Shares. A sufficient number of Shares issuable pursuant
to this Agreement has been duly authorized and reserved for issuance (subject to
adjustment pursuant to the Company's covenant set forth in Section 5(f) below)
pursuant to this Agreement. Upon issuance in accordance with this Agreement, the
Securities will be validly issued, fully paid and nonassessable and free from
all taxes, liens and charges with respect to the issue thereof. In the event the
Company cannot register a sufficient number of Shares, due to the remaining
number of authorized shares of Common Stock being insufficient, the Company will
use its best efforts to register the maximum number of shares it can based on
the remaining balance of authorized shares and will use its best efforts to
increase the number of its authorized shares as soon as reasonably practicable.

         e. No Conflicts. The execution, delivery and performance of the
Transaction Documents by the Company and the consummation by the Company of the
transactions contemplated hereby and thereby will not (i) result in a violation
of the Articles of Incorporation, any Certificate of Designations, Preferences
and Rights of any outstanding series of preferred stock of the Company or the
By-laws or (ii) conflict with, or constitute a material default (or an event
which with notice or lapse of time or both would become a material default)
under, or give to others any rights of termination, amendment, acceleration or
cancellation of, any material agreement, contract, indenture mortgage,
indebtedness or instrument to which the Company or any of its Subsidiaries is a
party, or result in a violation of any law, rule, regulation, order, judgment or
decree (including United States federal and state securities laws and
regulations and the rules and regulations of the Principal Market or principal
securities exchange or trading market on which the Common Stock is traded or
listed) applicable to the Company or any of its Subsidiaries or by which any
property or asset of the Company or any of its Subsidiaries is bound or
affected. Except as disclosed in Schedule 4(e), neither the Company nor its
Subsidiaries is in violation of any term of, or in default under, the Articles
of Incorporation, any Certificate of Designations, Preferences and Rights of any
outstanding series of preferred stock of the Company or the By-laws or their
organizational charter or by-laws, respectively, or any contract, agreement,
mortgage, indebtedness, indenture, instrument, judgment, decree or order or any
statute, rule or regulation applicable to the Company or its Subsidiaries,
except for possible conflicts, defaults, terminations, amendments,
accelerations, cancellations and violations that

<PAGE>

would not individually or in the aggregate have a Material Adverse Effect. The
business of the Company and its Subsidiaries is not being conducted, and shall
not be knowingly conducted, in violation of any law, statute, ordinance, rule,
order or regulation of any governmental authority or agency, regulatory or
self-regulatory agency, or court, except for possible violations the sanctions
for which either individually or in the aggregate would not have a Material
Adverse Effect. Except as specifically contemplated by this Agreement and as
required under the 1933 Act, the Company is not required to obtain any consent,
authorization, permit or order of, or make any filing or registration (except
the filing of a registration statement) with, any court, governmental authority
or agency, regulatory or self-regulatory agency or other third party in order
for it to execute, deliver or perform any of its obligations under, or
contemplated by, the Transaction Documents in accordance with the terms hereof
or thereof. All consents, authorizations, permits, orders, filings and
registrations which the Company is required to obtain pursuant to the preceding
sentence have been obtained or effected on or prior to the date hereof and are
in full force and effect as of the date hereof. Except as disclosed in Schedule
4(e), the Company and its Subsidiaries are unaware of any facts or circumstances
which might give rise to any of the foregoing. The Company is not, and will not
be, in violation of the listing requirements of the Principal Market as in
effect on the date hereof and on each of the Closing Dates and is not aware of
any facts which would reasonably lead to delisting of the Common Stock by the
Principal Market in the foreseeable future.

         f. SEC Documents; Financial Statements. The Company has filed and
during the Open Period will file all reports, schedules, forms, statements and
other documents required to be filed by it with the SEC pursuant to the
reporting requirements of the 1934 Act (all of the foregoing filed prior to the
date hereof and all exhibits included therein and financial statements and
schedules thereto and documents incorporated by reference therein being
hereinafter referred to as the "SEC Documents"). The Company has delivered to
the Investor or its representatives, or they have had access through EDGAR, true
and complete copies of the SEC Documents. As of their respective dates, the SEC
Documents complied in all material respects with the requirements of the 1934
Act and the rules and regulations of the SEC promulgated thereunder applicable
to the SEC Documents, and none of the SEC Documents, at the time they were filed
with the SEC, contained any untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading. As of their respective dates, the financial statements of the
Company included in the SEC Documents complied as to form in all material
respects with applicable accounting requirements and the published rules and
regulations of the SEC with respect thereto. Such financial statements have been
prepared in accordance with generally accepted accounting principles,
consistently applied, during the periods involved (except (i) as may be
otherwise indicated in such financial statements or the notes thereto, or (ii)
in the case of unaudited interim statements, to the extent they may exclude
footnotes or may be condensed or summary statements) and fairly present in all
material respects the financial position of the Company as of the dates thereof
and the results of its operations and cash flows for the periods then ended
(subject, in the case of unaudited statements, to normal year-end audit
adjustments). No other written information provided by or on behalf of the
Company to the Investor which is not included in the SEC Documents, including,
without limitation, information referred to in Section 4(d) of this Agreement,
contains any untrue statement of a material fact or omits to state any material
fact necessary to make the statements

<PAGE>

therein, in the light of the circumstance under which they are or were made, not
misleading. Neither the Company nor any of its Subsidiaries or any of their
officers, directors, employees or agents have provided the Investor with any
material, nonpublic information which was not publicly disclosed prior to the
date hereof and any material, nonpublic information provided to the Investor by
the Company or its Subsidiaries or any of their officers, directors, employees
or agents prior to any Closing Date shall be publicly disclosed by the Company
prior to such Closing Date.

         g. Absence of Certain Changes. Except as disclosed in Schedule 4(g) or
the SEC Documents filed at least five (5) days prior to the date hereof, there
has been no change or development in the business, properties, assets,
operations, financial condition, results of operations or prospects of the
Company or its Subsidiaries which has had or reasonably could have a Material
Adverse Effect. The Company has not taken any steps, and does not currently
expect to take any steps, to seek protection pursuant to any bankruptcy law nor
does the Company or its Subsidiaries have any knowledge or reason to believe
that its creditors intend to initiate involuntary bankruptcy proceedings.

         h. Absence of Litigation. Except as set forth in Schedule 4(h) or in
the SEC Documents, there is no action, suit, proceeding, inquiry or
investigation before or by any court, public board, government agency,
self-regulatory organization or body pending or, to the knowledge of the
executive officers of Company or any of its Subsidiaries, threatened against or
affecting the Company, the Common Stock or any of the Company's Subsidiaries or
any of the Company's or the Company's Subsidiaries' officers or directors in
their capacities as such, in which an adverse decision could have a Material
Adverse Effect.

         i. Acknowledgment Regarding Investor's Purchase of Shares. The Company
acknowledges and agrees that the Investor is acting solely in the capacity of
arm's length purchaser with respect to the Transaction Documents and the
transactions contemplated hereby and thereby. The Company further acknowledges
that the Investor is not acting as a financial advisor or fiduciary of the
Company (or in any similar capacity) with respect to the Transaction Documents
and the transactions contemplated hereby and thereby and any advice given by the
Investor or any of its respective representatives or agents in connection with
the Transaction Documents and the transactions contemplated hereby and thereby
is merely incidental to the Investor's purchase of the Securities. The Company
further represents to the Investor that the Company's decision to enter into the
Transaction Documents has been based solely on the independent evaluation by the
Company and its representatives.

         j. No Undisclosed Events, Liabilities, Developments or Circumstances.
To the best of the Company's knowledge after due inquiry and investigation, no
event, liability, development or circumstance has occurred or exists, or is
contemplated to occur, with respect to the Company or its Subsidiaries or their
respective business, properties, assets, prospects, operations or financial
condition, that would be required to be disclosed by the Company under
applicable securities laws on a registration statement filed with the SEC
relating to an issuance and sale by the Company of its Common Stock and which
has not been publicly announced.

<PAGE>

         k. Employee Relations. Neither the Company nor any of its Subsidiaries
is involved in any union labor dispute nor, to the knowledge of the Company or
any of its Subsidiaries, is any such dispute threatened. Neither the Company nor
any of its Subsidiaries is a party to a collective bargaining agreement, and the
Company and its Subsidiaries believe that relations with their employees are
good. No executive officer (as defined in Rule 501(f) of the 1933 Act) has
notified the Company that such officer intends to leave the Company's employ or
otherwise terminate such officer's employment with the Company.

         l. Intellectual Property Rights. The Company and its Subsidiaries own
or possess adequate rights or licenses to use all trademarks, trade names,
service marks, service mark registrations, service names, patents, patent
rights, copyrights, inventions, licenses, approvals, governmental
authorizations, trade secrets and rights necessary to conduct their respective
businesses as now conducted. Except as set forth on Schedule 4(l) or the SEC
Documents, none of the Company's trademarks, trade names, service marks, service
mark registrations, service names, patents, patent rights, copyrights,
inventions, licenses, approvals, government authorizations, trade secrets or
other intellectual property rights necessary to conduct its business as now or
as proposed to be conducted have expired or terminated, or are expected to
expire or terminate within two years from the date of this Agreement. The
Company and its Subsidiaries do not have any knowledge of any infringement by
the Company or its Subsidiaries of trademark, trade name rights, patents, patent
rights, copyrights, inventions, licenses, service names, service marks, service
mark registrations, trade secret or other similar rights of others, or of any
such development of similar or identical trade secrets or technical information
by others and, except as set forth on Schedule 4(l), there is no claim, action
or proceeding being made or brought against, or to the Company's knowledge,
being threatened against, the Company or its Subsidiaries regarding trademark,
trade name, patents, patent rights, invention, copyright, license, service
names, service marks, service mark registrations, trade secret or other
infringement; and the Company and its Subsidiaries are unaware of any facts or
circumstances which might give rise to any of the foregoing. The Company and its
Subsidiaries have taken reasonable security measures to protect the secrecy,
confidentiality and value of all of their intellectual properties.

         m. Environmental Laws. The Company and its Subsidiaries (i) are in
compliance with any and all applicable foreign, federal, state and local laws
and regulations relating to the protection of human health and safety, the
environment or hazardous or toxic substances or wastes, pollutants or
contaminants ("Environmental Laws"), (ii) have received all permits, licenses or
other approvals required of them under applicable Environmental Laws to conduct
their respective businesses and (iii) are in compliance with all terms and
conditions of any such permit, license or approval where, in each of the three
foregoing cases, the failure to so comply would have, individually or in the
aggregate, a Material Adverse Effect.

         n. Title. The Company and its Subsidiaries have good and marketable
title in fee simple to all real property and good and marketable title to all
personal property owned by them which is material to the business of the Company
and its Subsidiaries, in each case free and clear of all liens, encumbrances and
defects except such as are described in Schedule 4(n) or the SEC Documents, have
been incurred in the ordinary course of business, or such as do not materially
affect the value of such property and do not interfere with the use made and
proposed to be made

<PAGE>

of such property by the Company or any of its Subsidiaries. Any real property
and facilities held under lease by the Company or any of its Subsidiaries are
held by them under valid, subsisting and enforceable leases with such exceptions
as are not material and do not interfere with the use made and proposed to be
made of such property and buildings by the Company and its Subsidiaries.

         o. Insurance. The Company and each of its Subsidiaries are insured by
insurers of recognized financial responsibility against such losses and risks
and in such amounts as management of the Company believes to be prudent and
customary in the businesses in which the Company and its Subsidiaries are
engaged. Neither the Company nor any such Subsidiary has been refused any
insurance coverage sought or applied for and neither the Company nor any such
Subsidiary has any reason to believe that it will not be able to renew its
existing insurance coverage as and when such coverage expires or to obtain
similar coverage from similar insurers as may be necessary to continue its
business at a cost that would not have a Material Adverse Effect.

         p. Regulatory Permits. The Company and its Subsidiaries have in full
force and effect all certificates, approvals, authorizations and permits from
the appropriate federal, state, local or foreign regulatory authorities and
comparable foreign regulatory agencies, necessary to own, lease or operate their
respective properties and assets and conduct their respective businesses, and
neither the Company nor any such Subsidiary has received any notice of
proceedings relating to the revocation or modification of any such certificate,
approval, authorization or permit, except for such certificates, approvals,
authorizations or permits which if not obtained, or such revocations or
modifications which, would not have a Material Adverse Effect.

         q. Internal Accounting Controls. The Company and each of its
Subsidiaries maintain a system of internal accounting controls sufficient to
provide reasonable assurance that (i) transactions are executed in accordance
with management's general or specific authorizations, (ii) transactions are
recorded as necessary to permit preparation of financial statements in
conformity with generally accepted accounting principles and to maintain asset
accountability, (iii) access to assets is permitted only in accordance with
management's general or specific authorization and (iv) the recorded
accountability for assets is compared with the existing assets at reasonable
intervals and appropriate action is taken with respect to any differences.

         r. No Materially Adverse Contracts, Etc. Neither the Company nor any of
its Subsidiaries is subject to any charter, corporate or other legal
restriction, or any judgment, decree, order, rule or regulation which in the
judgment of the Company's officers has or is expected in the future to have a
Material Adverse Effect. Neither the Company nor any of its Subsidiaries is a
party to any contract or agreement which in the judgment of the Company's
officers has or is expected to have a Material Adverse Effect.

         s. Tax Status. The Company and each of its Subsidiaries has made or
filed all United States federal and state income and all other tax returns,
reports and declarations required by any jurisdiction to which it is subject
(unless and only to the extent that the Company and each of its Subsidiaries has
set aside on its books provisions reasonably adequate for the payment

<PAGE>

of all unpaid and unreported taxes) and has paid all taxes and other
governmental assessments and charges that are material in amount, shown or
determined to be due on such returns, reports and declarations, except those
being contested in good faith and has set aside on its books provision
reasonably adequate for the payment of all taxes for periods subsequent to the
periods to which such returns, reports or declarations apply. There are no
unpaid taxes in any material amount claimed to be due by the taxing authority of
any jurisdiction, and the officers of the Company know of no basis for any such
claim.

         t. Certain Transactions. Except as set forth on Schedule 4(t) and in
the SEC Documents filed at least ten days prior to the date hereof and except
for arm's length transactions pursuant to which the Company makes payments in
the ordinary course of business upon terms no less favorable than the Company
could obtain from third parties and other than the grant of stock options
disclosed on Schedule 4(c), none of the officers, directors, or employees of the
Company is presently a party to any transaction with the Company or any of its
Subsidiaries (other than for services as employees, officers and directors),
including any contract, agreement or other arrangement providing for the
furnishing of services to or by, providing for rental of real or personal
property to or from, or otherwise requiring payments to or from any officer,
director or such employee or, to the knowledge of the Company, any corporation,
partnership, trust or other entity in which any officer, director, or any such
employee has a substantial interest or is an officer, director, trustee or
partner.

         u. Dilutive Effect. The Company understands and acknowledges that the
number of shares of Common Stock issuable upon purchases pursuant to this
Agreement will increase in certain circumstances including, but not necessarily
limited to, the circumstance wherein the trading price of the Common Stock
declines during the period between the Effective Date and the end of the Open
Period. The Company's executive officers and directors have studied and fully
understand the nature of the transactions contemplated by this Agreement and
recognize that they have a potential dilutive effect. The board of directors of
the Company has concluded, in its good faith business judgment, that such
issuance is in the best interests of the Company. The Company specifically
acknowledges that, subject to such limitations as are expressly set forth in the
Transaction Documents, its obligation to issue shares of Common Stock upon
purchases pursuant to this Agreement is absolute and unconditional regardless of
the dilutive effect that such issuance may have on the ownership interests of
other shareholders of the Company.

         v. Right of First Refusal. The Company shall not, directly or
indirectly, without the prior written consent of Investor offer, sell, grant any
option to purchase, or otherwise dispose of (or announce any offer, sale, grant
or any option to purchase or other disposition) any of its Common Stock or
securities convertible into Common Stock at a price that is less than the market
price of the Common Stock at the time of issuance of such security or investment
if any such Common Stock or such securities have attached registration rights or
otherwise have no restrictions on resale pursuant to Rule 144 or otherwise and
such registration statement will become effective during the Open Period (a
"Subsequent Financing") for a period of two (2) months prior to or following
each Closing Date, except (i) the granting of options or warrants to employees,
officers, directors and consultants, and the issuance of shares upon exercise of
options granted, under any stock option plan heretofore or hereinafter duly
adopted by the

<PAGE>

Company, (ii) shares issued upon exercise of any currently outstanding warrants
or options and upon conversion of any currently outstanding convertible
debenture or convertible preferred stock, in each case disclosed pursuant to
Section 4(c), (iii) securities issued in connection with the capitalization or
creation of a joint venture with a strategic partner, (iv) shares issued to pay
part or all of the purchase price for the acquisition by the Company of another
entity (which, for purposes of this clause (iv), shall not include an individual
or group of individuals), and (v) shares issued in a bona fide public offering
by the Company of its securities, unless (A) the Company delivers to Investor a
written notice (the "Subsequent Financing Notice") of its intention to effect
such Subsequent Financing, which Subsequent Financing Notice shall describe in
reasonable detail the proposed terms of such Subsequent Financing, the amount of
proceeds intended to be raised thereunder, the person with whom such Subsequent
Financing shall be effected, and attached to which shall be a term sheet or
similar document relating thereto and (B) Investor shall not have notified the
Company by 5:00 p.m. (New York time) on the fifth (5th) Trading Day after its
receipt of the Subsequent Financing Notice of its willingness to provide,
subject to completion of mutually acceptable documentation, financing to the
Company on substantially the terms set forth in the Subsequent Financing Notice.
If Investor shall fail to notify the Company of its intention to enter into such
negotiations within such time period, then the Company may effect the Subsequent
Financing substantially upon the terms set forth in the Subsequent Financing
Notice; provided that the Company shall provide Investor with a second
Subsequent Financing Notice, and Investor shall again have the right of first
refusal set forth above in this Section, if the Subsequent Financing subject to
the initial Subsequent Financing Notice shall not have been consummated for any
reason on the terms set forth in such Subsequent Financing Notice within thirty
(30) Trading Days after the date of the initial Subsequent Financing Notice. The
rights granted to Investor in this Section are not subject to any prior right of
first refusal given to any other person except as disclosed on Schedule 4(c).

         v. No General Solicitation. Neither the Company, nor any of its
affiliates, nor any person acting on its behalf, has engaged in any form of
general solicitation or general advertising (within the meaning of Regulation D)
in connection with the offer or sale of the Common Stock offered hereby.

5.       COVENANTS OF THE COMPANY.

         a. Best Efforts. The Company shall use its best efforts timely to
satisfy each of the conditions to be satisfied by it as provided in Section 7 of
this Agreement.

         b. Blue Sky. The Company shall, at its sole cost and expense, on or
before each of the Closing Dates, take such action as the Company shall
reasonably determine is necessary to qualify the Securities for, or obtain
exemption for the Securities for, sale to the Investor at each of the Closings
pursuant to this Agreement under applicable securities or "Blue Sky" laws of
such states of the United States, as specified by Investor, and shall provide
evidence of any such action so taken to the Investor on or prior to the Closing
Date. The Company shall, at its sole cost and expense, make all filings and
reports relating to the offer and sale of the Securities required under the

restriction pursuant to Rule 144(k) promulgated under the 1933 Act (or successor
thereto), or (ii) the date on which (A) the Holders shall have sold all the

Company shall take all action necessary to at all times have authorized, and
reserved for the purpose of issuance, a sufficient number of shares of Common
Stock to provide for the issuance of the Securities hereunder. In the event that
the Company determines that it does not have a sufficient number of authorized
shares of Common Stock to reserve and keep available for issuance as described
in this Section 5(f), the Company shall use its best efforts to increase the
number of authorized shares of Common Stock by seeking shareholder approval for
the authorization of such additional shares.

         g. Listing. The Company shall promptly secure the listing of all of the
Registrable Securities (as defined in the Registration Rights Agreement) upon
the Principal Market and each other national securities exchange and automated

other shares of Common Stock shall be so listed, such listing of all Registrable
Securities from time to time issuable under the terms of the Transaction
Documents. The Company shall maintain the Common Stock's authorization for
quotation on the Principal Market. Neither the Company nor any of its
Subsidiaries shall take any action which would be reasonably expected to result
in the delisting or suspension of the Common Stock on the Principal Market
(excluding suspensions of not more than one trading day resulting from business
announcements by the Company). The Company shall promptly provide to the
Investor copies of any notices it receives

<PAGE>

from the Principal Market regarding the continued eligibility of the Common

interest (each a "Related Party"), except for (i) customary employment
arrangements and benefit programs on reasonable terms, (ii) any agreement,
transaction, commitment or arrangement on an arms-length basis on terms no less
favorable than terms which would have been obtainable from a person other than
such Related Party, or (iii) any agreement, transaction, commitment or
arrangement which is approved by a majority of the disinterested directors of
the Company. For purposes hereof, any director who is also an officer of the

(ii) the issuance by the SEC or any other federal or state governmental
authority of any stop order suspending the effectiveness of any Registration
Statement or the initiation of any proceedings for that purpose; (iii) receipt
of any notification with respect to the suspension of the qualification or
exemption from qualification of any of the Shares for sale in any jurisdiction
or the initiation or threatening of any proceeding for such purpose; (iv) the
happening of any event that makes any statement made in such Registration
Statement or related prospectus or any document incorporated or

<PAGE>

deemed to be incorporated therein by reference untrue in any material respect or
that requires the making of any changes in the Registration Statement, related
prospectus or documents so that, in the case of a Registration Statement, it
will not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading, and that in the case of the related prospectus, it will
not contain any untrue statement of a material fact or omit to state any

shall promptly make available to Investor any such supplement or amendment to
the related prospectus. The Company shall not deliver to Investor any Put Notice
during the continuation of any of the foregoing events.

         l. Reimbursement. If (i) Investor, other than by reason of its gross
negligence, fraud, misrepresentation, providing materially untrue or inaccurate

willful misconduct (each an "Excluded Act"), becomes involved in any capacity in
any action, proceeding or investigation brought by any shareholder of the
Company, in connection with or as a result of the consummation of the
transactions contemplated by the Transaction Documents, or if Investor is
impleaded in any such action, proceeding or investigation by any person for any
reason other than for an Excluded Act, or (ii) Investor, other than by reason of
an Excluded Act, becomes involved in any capacity in any action, proceeding or
investigation brought by the SEC against or involving the Company or in
connection with or as a result of the consummation of the transactions

such action, proceeding or investigation by any person, then in any such case,
the Company will reimburse Investor for its reasonable legal and other expenses
(including the cost of any investigation and preparation) incurred in connection
therewith, as such expenses are incurred. The reimbursement obligations of the
Company under this section shall be in addition to any liability which the
Company may otherwise have, shall extend upon the same terms and conditions to
any affiliates of Investor that are actually named in such action, proceeding or
investigation, and partners, directors, agents, employees, attorneys,
accountants, auditors and controlling persons (if any), as the case may be, of

benefit of any successors of the Company, Investor and any such affiliate and
any such person.

6.       COVER.

         If, the number of Shares represented by any Put Notices become
restricted or are no longer freely trading for any reason, and after the
applicable Closing Date, the Investor purchases, in an open market transaction
or otherwise, the Company's Common Stock (the "Covering Shares") in order to
make delivery in satisfaction of a sale of Common Stock by the Investor (the
"Sold Shares"), which delivery such Investor anticipated to make using the
Shares represented by the Put Notice (a "Buy-In"), the Company shall pay to the
Investor the Buy-In Adjustment Amount (as defined below). The "Buy-In Adjustment
Amount" is the amount equal to the excess, if any, of (a) the Investor's total
purchase price (including brokerage commissions, if any) for the Covering Shares
over (b) the net proceeds (after brokerage commissions, if any) received by the
Investor from the sale of the Sold Shares. The Company shall pay the Buy-In
Adjustment Amount to the Investor in immediately available funds immediately
upon demand by

<PAGE>

the Investor. By way of illustration and not in limitation of the foregoing, if
the Investor purchases Common Stock having a total purchase price (including
brokerage commissions) of eleven thousand dollars ($11,000) to cover a Buy-In
with respect to the Common Stock it sold for net proceeds of ten thousand
dollars ($10,000), the Buy-In Adjustment Amount which the Company will be
required to pay to the Investor will be one thousand dollars ($1,000).

in consultation with its counsel.

advisor or consultant, finder, placement agent, investment banker, bank or other
person or entity, with respect to the transactions contemplated by the
Transaction Documents other than to Capstone Partners, L.C. and Crescent Fund
LLC. The Investor shall have no obligation with respect to any fees or with
respect to any claims made by or on behalf of persons or entities for fees of a
type contemplated in this Section that may be due in connection with the
transactions contemplated by the Transaction Documents. The Company shall
indemnify and hold harmless the Investor, their employees, officers, directors,
agents, attorneys (including Novack Burnbaum Crystal LLP) and partners, and
their respective affiliates, from and against all claims, losses, damages, costs
(including the costs of preparation and attorney's fees) and expenses incurred

                             SCHEDULES TO AGREEMENT

SCHEDULE 4(c)

         The following registration rights have been granted by Invisa: 500,000
options at $3.50 per share; 3,685,000 shares issued to affiliates/founders, as
part of an acquisition; up to 400,000 shares at $3.00 per share or greater;
250,000 warrants at $1.00 per share with registration rights after June 8, 2004;
and 8,375 options at $5.50 per share.

         Invisa has the following redemption rights: up to 400,000 shares are
subject to a redemption right with the redemption price being paid only by a
13-month promissory note with one payment of principal and interest; and 3,750
options can be redeemed by the Company at $.10 per option.

SCHEDULE 4(h)

         A vendor, Singletec, has asserted a litigation threat against Invisa
for an account payable allegedly in the approximate amount of $91,000. The
amount due is disputed; however, a settlement/payment schedule has been
tentatively negotiated.

SCHEDULE 4(o)

         A wrongful employee termination insurance policy was not renewed.

SCHEDULE 4(t)

         The Company amended an agreement with affiliated parties arising out of
the acquisition of patents and other assets by Invisa. The amendment eliminated
the issuance of a potential convertible promissory note and resulted in the
issuance of additional shares of common stock. All of the shares of common stock
have been issued and are reflected in Paragraph 4(c) as being duly issued and
outstanding at the date of this agreement.

                           FORM OF OPINION OF COUNSEL

May ___, 2003

         RE:      INVISA, INC.

Ladies and Gentlemen:

         We have acted as counsel to Invisa, Inc., a corporation incorporated
under the laws of the State of Nevada ("Company"), in connection with the Series
2003-A 7% Convertible Note, the Investment Agreement, the Financing Agreement,
the Pledge Agreement, the Registration Rights Agreement, the Warrant, the Escrow
Agreement, and the Instructions to Transfer Agent, all dated as of May 7, 2003
(the "Transaction Documents"), and the issuance and sale of shares of common
stock pursuant to the Transaction Documents.

         In connection with rendering the opinions set forth herein, we have
examined drafts of the Transaction Documents, the Company's Certificate of
Incorporation, and its Bylaws, as amended to date, the proceedings of the
Company's Board of Directors taken in connection with entering into the
Transaction Documents, and such other documents, agreements and records as we
deemed necessary to render the opinions set forth below.

         In conducting our examination, we have assumed the following: (i) that
each of the Transaction Documents has been executed by each of the parties
thereto in the same form as the forms which we have examined, (ii) the
genuineness of all signatures, the legal capacity of natural persons, the
authenticity and accuracy of all documents submitted to us as originals, and the
conformity to originals of all documents submitted to us as copies, (iii) that
each of the Transaction Documents has been duly and validly authorized, executed
and delivered by the party or parties thereto other than the Company, and (iv)
that each of the Transaction Documents constitutes the valid and binding
agreement of the party or parties thereto other than the Company, enforceable
against such party or parties in accordance with the Transaction Documents'
terms.

         Based upon the subject to the foregoing, we are of the opinion that:

         1. The Company has been duly incorporated and is validly existing as a
corporation in good standing under the laws of the State of Nevada, is duly
qualified to do business as a foreign corporation and is in good standing in all
jurisdictions where the Company owns or leases properties, maintains employees
or conducts business, except for jurisdictions in which the failure to so
qualify would not have a material adverse effect on the Company, and has all
requisite corporate power and authority to own its properties and conduct its
business.

<PAGE>

         2. The authorized capital stock of the Company consists of 95,000,000
shares of Common Stock, $.001 par value per share, ("Common Stock") and
5,000,000 Preferred Stock, par value $.001 per share;

         3. The Common Stock is registered pursuant to Section 12(b) or Section
12(g) of the Securities Exchange Act of 1934, as amended;

         4. When duly countersigned by the Company's transfer agent and
registrar, and delivered to you or upon your order against payment of the agreed
consideration therefor in accordance with the provisions of the Transaction
Documents, the Common Stock to be issued upon the conversion of the Series
2003-A 7% Convertible Note, as described in the Transaction Documents
represented thereby and shares issued under the Investment Agreement will be
duly authorized and validly issued, fully paid and non-assessable;

         5 The Company has the requisite corporate power and authority to enter
into the Transaction Documents and to sell and deliver the Securities and the
Common Stock to be issued as described in the Transaction Documents; each of the
Transaction Documents has been duly and validly authorized by all necessary
corporate action by the Company to our knowledge, no approval of any
governmental or other body is required for the execution and delivery of each of
the Transaction Documents by the Company or the consummation of the transactions
contemplated thereby (other than the SEC or applicable state securities agencies
under the Registration Rights Agreement); each of the Transaction Documents has
been duly and validly executed and delivered by and on behalf of the Company,
and is a valid and binding agreement of the Company, enforceable in accordance
with its terms, except as enforceability may be limited by general equitable
principles, bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium or other laws affecting creditors rights generally, and except as to
compliance with federal, state, and foreign securities laws, as to which no
opinion is expressed;

         6. To the best of our knowledge, after due inquiry, the execution,
delivery and performance of the Transaction Documents and the performance of its
obligations thereunder do not and will not constitute a breach or violation of
any of the terms and provisions of, or constitute a default under or conflict
with or violate any provision of (i) the Company's Certificate of Incorporation
or By-Laws, (ii) any indenture, mortgage, deed of trust, agreement or other
instrument to which the Company is party or by which it or any of its property
is bound, (iii) any applicable statute or regulation or as other, (iv) or any
judgment, decree or order of any court or governmental body having jurisdiction
over the Company or any of its property.

         7. The issuance of Common Stock upon conversion of the Series 2003-A 7%
Convertible Note ("Convertible Note"), in accordance with the terms and
conditions of the Transaction Documents, will not violate the applicable listing
agreement between the Company and any securities exchange or market on which the
Company's securities are listed.

         8. To the best of our knowledge, after due inquiry, there is no pending
or threatened litigation, investigation or other proceedings against the Company
except as described in the reports filed with the SEC and in the Transaction
Documents or Schedules thereto.

<PAGE>

         9. The Transaction Documents are not usurious within the definition of
any laws, rules or regulations applicable to the Transaction Documents. The
Transaction Documents are not rendered unenforceable by virtue of any assertion
of a defense which may be based upon usury.

         10. The Company complies with the eligibility requirements for the use
of Form SB-2, under the Securities Act of 1933, as amended.

         This opinion is rendered only with regard to the matters set out in the
numbered paragraphs above. No other opinions are intended nor should they be
inferred. This opinion is based solely upon the laws of the United States and
the State of Nevada and does not include an interpretation or statement
concerning the laws of any other state or jurisdiction. Insofar as the
enforceability of the Transaction Documents and Securities may be governed by
the laws of other states, we have assumed that such laws are identical in all
respects to the laws of the State of Nevada.

         The opinions expressed herein are given to you solely for your use in
connection with the transaction contemplated by the Transaction Documents and
Securities and may not be relied upon by any other person or entity or for any
other purpose without our prior consent.

                                           Very truly yours,

                                           By:
                                               ---------------------------------

and (iii) twenty-five thousand (25,000) Shares shall be vested and exercisable
on the date that, and only if, the Company has received $1,000,000 in aggregate
financing under the Investment Agreement.

         This Warrant is subject to the following provisions, terms and
conditions:

         SECTION 1. TRANSFERABILITY.

         1.1 REGISTRATION. The Warrants shall be issued only in registered form.

         1.2 TRANSFER. This Warrant shall be transferable only on the books of
the Company maintained at its principal executive offices upon surrender thereof
for registration of transfer duly endorsed by the Warrantholder or by its duly
authorized attorney or representative, or accompanied by proper evidence of
succession, assignment or authority to transfer. Upon any registration of
transfer, the Company shall execute and deliver a new Warrant or Warrants in
appropriate denominations to the person or persons entitled thereto.

         1.3 COMMON STOCK TO BE ISSUED. Upon the exercise of any vested Warrants
and upon receipt by the Company of a facsimile or original of Warrantholder's

denominations to be specified by Warrantholder representing the number of shares
of Common Stock issuable upon such exercise, as applicable. Company warrants
that no instructions, other than these instructions, have been given or will be

<PAGE>

shall otherwise be freely transferable on the books and records of the Company.
It shall be the Company's responsibility to take all necessary actions and to
bear all such costs to issue the certificates of Common Stock as provided

to the transfer agent, if so required. The person in whose name the certificates
of Common Stock is to be registered shall be treated as a shareholder of record
on and after the exercise date. Upon surrender of any Warrant that is to be
converted in part, the Company shall issue to the Warrantholder a new Warrant
equal to the unconverted amount, if so requested by Purchaser:

         THE SECURITIES OFFERED HEREBY HAVE NOT BEEN AND WILL NOT BE REGISTERED
         UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, AND THE
         RULES AND REGULATIONS PROMULGATED THEREUNDER (THE "1933 ACT"), AND MAY
         NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO REGISTRATION UNDER OR AN
         EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE 1933 ACT.

         SECTION 2. EXCHANGE OF WARRANT CERTIFICATE. Any Warrant certificate may
be exchanged for another certificate or certificates of like tenor entitling the
Warrantholder to purchase a like aggregate number of Shares as the certificate
or certificates surrendered then entitle such Warrantholder to purchase. Any
Warrantholder desiring to exchange a warrant certificate shall make such request
in writing delivered to the Company, and shall surrender, properly endorsed, the
certificate evidencing the Warrant to be so exchanged. Thereupon, the Company
shall execute and deliver to the person entitled thereto a new Warrant
certificate as so requested.

         SECTION 3. TERMS OF WARRANTS: EXERCISE OF WARRANTS.

         (a) Subject to the terms of this Warrant, the Warrantholder shall have
the right, at any time commencing on May ___, 2003, but before 5:00 p.m. Pacific
Time on May ___, 2008 ("Expiration Time"), to purchase from the Company up to
the number of Shares which the Warrantholder may at the time be entitled to
purchase pursuant to the terms of this Warrant, upon surrender to the Company at
its principal executive office, of the certificate evidencing this Warrant to be
exercised, together with the attached Election to Exercise Warrant form duly
filled in and signed, and upon payment to the Company of the Warrant Price (as
defined in and determined in accordance with the provisions of Section 7 and 8
hereof) or as provided in Section 3(a)(i) hereof, for the number of Shares with
respect to which such Warrant is then exercised. Payment of the aggregate
Warrant Price shall be made in cash, wire transfer or by cashier's check or any
combination thereof.

         (b) Subject to the terms of this Warrant, upon such surrender of this
Warrant and payment of such Warrant Price as aforesaid, the Company shall
promptly issue and cause to be delivered to the Warrantholder or to such person
or persons as the Warrantholder may designate in writing, a certificate or
certificates (in such name or names as the Warrantholder may designate in
writing) for the number of duly authorized, fully paid and non-assessable whole
Shares to be purchased upon the exercise of this Warrant, and shall deliver to
the Warrantholder Common Stock or cash, to the extent provided in Section 9
hereof, with respect to any fractional

<PAGE>

Shares otherwise issuable upon such surrender. Such certificate or certificates
shall be deemed to have been issued and any person so designated to be named
therein shall be deemed to have become a holder of such Shares as of the close
of business on the date of the surrender of this Warrant and payment of the
Warrant Price, notwithstanding that the certificates representing such Shares
shall not actually have been delivered or that the Share and Warrant transfer
books of the Company shall then be closed. This Warrant shall be exercisable, at
the sole election of the Warrantholder, either in full or from time to time in
part and, in the event that any certificate evidencing this Warrant (or any
portion thereof) is exercised prior to the Expiration Time with respect to less
than all of the Shares specified therein at any time prior to the Expiration
Time, a new certificate of like tenor evidencing the remaining portion of this
Warrant shall be issued by the Company, if so requested by the Warrantholder.

         (c) Upon the Company's receipt of a facsimile or original of
Warrantholder's signed Election to Exercise Warrant, the Company shall instruct
its transfer agent to issue one or more stock certificates representing that
number of shares of Common Stock which the Warrantholder is entitled to purchase
in accordance with the terms and conditions of this Warrant and the Election to
Exercise Warrant attached hereto. The Company shall act as Registrar and shall
maintain an appropriate ledger containing the necessary information with respect
to each Warrant and it shall not be necessary for the Warrantholder to send to
the Company the original Warrants to be exercised.

         (d) Such exercise shall be effectuated by sending to the Company, or
its attorney, a facsimile or original of the signed Election to Exercise Warrant
which evidences Warrantholder's intention to exercise those Warrants indicated.
The date on which the Election to Exercise Warrant is effective ("Exercise
Date") shall be deemed to be the date on which the Warrantholder has delivered
to the Company a facsimile or original of the signed Election to Exercise
Warrant. The Company shall deliver to the Warrantholder, or per the
Warrantholder's instructions, the shares of Common Stock within three (3)
business days of receipt of the Election to Exercise Warrants.

         (e) Nothing contained in this Warrant shall be deemed to establish or
require the payment of interest to the Warrantholder at a rate in excess of the
maximum rate permitted by governing law. In the event that the rate of interest
required to be paid exceeds the maximum rate permitted by governing law, the
rate of interest required to be paid thereunder shall be automatically reduced
to the maximum rate permitted under the governing law and such excess shall be
returned with reasonable promptness by the Warrantholder to the Company.

         (f) It shall be the Company's responsibility to take all necessary
actions and to bear all such costs to issue the certificate of Common Stock as
provided herein, including the responsibility and cost for delivery of an
opinion letter to the transfer agent, if so required. The person in whose name
the certificate of Common Stock is to be registered shall be treated as a
shareholder of record on and after the exercise date. Upon surrender of any
Warrants that are to be converted in part, the Company shall issue to the
Warrantholder new Warrants equal to the unconverted amount, if so requested by
Warrantholder.

         (g) The Company shall at all times reserve and have available all
Common Stock necessary to meet exercise of the Warrants by all Warrantholders of
the entire amount of

<PAGE>

Warrants then outstanding. If, at any time Warrantholder submits an Election to
Exercise Warrant and the Company does not have sufficient authorized but
unissued shares of Common Stock available to effect, in full, a exercise of the
Warrants (a "Exercise Default", the date of such default being referred to
herein as the "Exercise Default Date"), the Company shall issue to the
Warrantholder all of the shares of Common Stock which are available, and the
Election to Exercise Warrant as to any Warrants requested to be converted but
not converted (the "Unconverted Warrants"), upon Warrantholder's sole option,
may be deemed null and void. The Company shall provide notice of such Exercise
Default ("Notice of Exercise Default") to all existing Warrantholders of
outstanding Warrants, by facsimile, within one (1) business day of such default
(with the original delivered by overnight or two day courier), and the
Warrantholder shall give notice to the Company by facsimile within five (5)
business days of receipt of the original Notice of Exercise Default (with the
original delivered by overnight or two day courier) of its election to either
nullify or confirm the Election to Exercise Warrant.

         (h) Each person in whose name any certificate for shares of Common
Stock shall be issued shall for all purposes be deemed to have become the holder
of record of the Common Stock represented thereby on the date on which the
Warrant was surrendered and payment of the purchase price and any applicable
taxes was made, irrespective of date of issue or delivery of such certificate,
except that if the date of such surrender and payment is a date when the Shares
transfer books of the Company are closed, such person shall be deemed to have
become the holder of such Shares on the next succeeding date on which such Share
transfer books are open. The Company shall not close such Share transfer books
at any one time for a period longer than seven (7) days.

         (i) This Warrant is exercisable in whole or in part at the Exercise
Price per share of Common Stock (as defined hereafter) payable hereunder,
payable in cash or by certified or official bank check, by means of sending to
the Company, or its attorney, an Election to Exercise Warrants, as stated above,
to receive the number of shares of Common Stock stated in such Election or by
"cashless exercise" (only in the event the Shares underlying the Warrants have
not been registered in an effective Registration Statement), by means of sending
to the Company, or its attorney, an Election to Exercise Warrants, as stated
above, to receive a number of shares of Common Stock equal to the difference
between the Market Value (as defined hereafter) of the shares of Common Stock
issuable upon exercise of this Warrant and the total cash exercise price
thereof. Upon transmitting the annexed Notice of Exercise duly executed,
together with payment of the Exercise Price for the shares of Common Stock
purchased, or upon the "cashless exercise" as provided in this Section, the
Holder shall be entitled to receive a certificate or certificates for the shares
of Common Stock so purchased. For the purposes of this subsection, "Market
Value" shall be an amount equal to the average closing bid price of a share of
Common Stock for the ten (10) days preceding the Company's receipt of the Notice
of Exercise Form duly executed multiplied by the number of shares of Common
Stock to be issued upon surrender of this Warrant Certificate.

         SECTION 4. PAYMENT OF TAXES. The Company shall pay all documentary
stamp taxes, if any, attributable to the initial issuance of the Shares;
provided, however, that the Company shall not be required to pay any tax or
taxes which may be payable, (i) with respect to any secondary transfer of this
Warrant or the Shares or (ii) as a result of the issuance of the Shares to

<PAGE>

any person other than the Warrantholder, and the Company shall not be required
to issue or deliver any certificate for any Shares unless and until the person
requesting the issuance thereof shall have paid to the Company the amount of
such tax or shall have produced evidence that such tax has been paid to the
appropriate taxing authority.

         SECTION 5. MUTILATED OR MISSING WARRANT. In case the certificate or
certificates evidencing this Warrant shall be mutilated, lost, stolen or
destroyed, the Company shall, at the request of the Warrantholder, issue and
deliver in exchange and substitution for and upon cancellation of the mutilated
certificate or certificates, or in lieu of and substitution for the certificate
or certificates lost, stolen or destroyed, a new Warrant certificate or
certificates of like tenor and representing an equivalent right or interest, but
only upon receipt of evidence satisfactory to the Company of such loss, theft or
destruction of such Warrant and of a bond of indemnity, if requested, also
satisfactory to the Company in form and amount, and issued at the applicant's
cost. Applicants for such substitute Warrant certificate shall also comply with
such other reasonable regulations and pay such other reasonable charges as the
Company may prescribe.

         SECTION 6. RESERVATION OF SHARES. The issuance, sale and delivery of
the Warrants have been duly authorized by all required corporate action on the
part of the Company and when issued, sold and delivered in accordance with the
terms hereof and thereof for the consideration expressed herein and therein,
will be duly and validly issued, fully paid, and non-assessable and enforceable
in accordance with their terms, subject to the laws of bankruptcy and creditors'
rights generally. The Company shall pay all taxes in respect of the issue
thereof. As a condition precedent to the taking of any action that would result
in the effective purchase price per share of Common Stock upon the exercise of
this Warrant being less than the par value per share (if such shares of Common
Stock then have a par value), the Company will take such corporate action as
may, in the opinion of its counsel, be necessary in order that the Company may
comply with all its obligations under this Agreement with regard to the exercise
of this Warrant.

         SECTION 7. WARRANT PRICE. During the Exercise Period, the price per
Share ("Warrant Price") at which Shares shall be purchasable upon the exercise
of this Warrant shall be _____________ ($____).

         SECTION 8. ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES. The number
and kind of securities purchasable upon the exercise of this Warrant and the
Warrant Price shall be subject to adjustment from time to time after the date
hereof upon the happening of certain events, as follows:

         8.1 ADJUSTMENTS. The number of Shares purchasable upon the exercise of
this Warrant shall be subject to adjustments as follows:

         (a) In case the Company shall (i) pay a dividend on Common Stock in
Common Stock or securities convertible into, exchangeable for or otherwise
entitling a holder thereof to receive Common Stock, (ii) declare a dividend
payable in cash on its Common Stock and at substantially the same time offer its
shareholders a right to purchase new Common Stock (or securities convertible
into, exchangeable for or other entitling a holder thereof to receive

<PAGE>

Common Stock) from the proceeds of such dividend (all Common Stock so issued
shall be deemed to have been issued as a stock dividend), (iii) subdivide its
outstanding shares of Common Stock into a greater number of shares of Common
Stock, (iv) combine its outstanding shares of Common Stock into a smaller number
of shares of Common Stock, or (v) issue by reclassification of its Common Stock
any shares of Common Stock of the Company, the number of shares of Common Stock
issuable upon exercise of the Warrants immediately prior thereto shall be
adjusted so that the holders of the Warrants shall be entitled to receive after
the happening of any of the events described above that number and kind of
shares as the holders would have received had such Warrants been converted
immediately prior to the happening of such event or any record date with respect
thereto. Any adjustment made pursuant to this subdivision shall become effective
immediately after the close of business on the record date in the case of a
stock dividend and shall become effective immediately after the close of
business on the effective date in the case of a stock split, subdivision,
combination or reclassification.

         (b) In case the Company shall distribute, without receiving
consideration therefor, to all holders of its Common Stock evidences of its
indebtedness or assets (excluding cash dividends other than as described in
Section (8)(a)(ii)), then in such case, the number of shares of Common Stock
thereafter issuable upon exercise of the Warrants shall be determined by
multiplying the number of shares of Common Stock theretofore issuable upon
exercise of the Warrants, by a fraction, of which the numerator shall be the
closing bid price per share of Common Stock on the record date for such
distribution, and of which the denominator shall be the closing bid price of the
Common Stock less the then fair value (as determined by the Board of Directors
of the Company, whose determination shall be conclusive) of the portion of the
assets or evidences of indebtedness so distributed per share of Common Stock.
Such adjustment shall be made whenever any such distribution is made and shall
become effective immediately after the record date for the determination of
stockholders entitled to receive such distribution.

         (c) Any adjustment in the number of shares of Common Stock issuable
hereunder otherwise required to be made by this Section 8 will not have to be
adjusted if such adjustment would not require an increase or decrease in one
percent (1%) or more in the number of shares of Common Stock issuable upon
exercise of the Warrant. No adjustment in the number of Shares purchasable upon
exercise of this Warrant will be made for the issuance of shares of capital
stock to directors, employees or independent Warrantors pursuant to the
Company's or any of its subsidiaries' stock option, stock ownership or other
benefit plans or arrangements or trusts related thereto or for issuance of any
shares of Common Stock pursuant to any plan providing for the reinvestment of
dividends or interest payable on securities of the Company and the investment of
additional optional amounts in shares of Common Stock under such plan.

         (d) Whenever the number of shares of Common Stock issuable upon the
exercise of the Warrants is adjusted, as herein provided the Warrant Price shall
be adjusted (to the nearest cent) by multiplying such Warrant Price immediately
prior to such adjustment by a fraction, of which the numerator shall be the
number of shares of Common Stock issuable upon the exercise of each share of the
Warrants immediately prior to such adjustment, and of which the denominator
shall be the number of shares of Common Stock issuable immediately thereafter.

<PAGE>

         (e) The Company from time to time by action of its Board of Directors
may decrease the Warrant Price by any amount for any period of time if the
period is at least twenty (20) days, the decrease is irrevocable during the
period and the Board of Directors of the Company in its sole discretion shall
have made a determination that such decrease would be in the best interest of
the Company, which determination shall be conclusive. Whenever the Warrant Price
is decreased pursuant to the preceding sentence, the Company shall mail to
holders of record of the Warrants a notice of the decrease at least fifteen (15)
days prior to the date the decreased Warrant Price takes effect, and such notice
shall state the decreased Warrant Price and the period it will be in effect.

         8.2 MERGERS, ETC. In the case of any (i) consolidation or merger of the
Company into any entity (other than a consolidation or merger that does not
result in any reclassification, exercise, exchange or cancellation of
outstanding shares of Common Stock of the Company), (ii) sale, transfer, lease
or conveyance of all or substantially all of the assets of the Company as an
entirety or substantially as an entirety, or (iii) reclassification, capital
reorganization or change of the Common Stock (other than solely a change in par
value, or from par value to no par value), in each case as a result of which
shares of Common Stock shall be converted into the right to receive stock,
securities or other property (including cash or any combination thereof), each
holder of Warrants then outstanding shall have the right thereafter to exercise
such Warrant only into the kind and amount of securities, cash and other
property receivable upon such consolidation, merger, sale, transfer, capital
reorganization or reclassification by a holder of the number of shares of Common
Stock of the Company into which such Warrants would have been converted
immediately prior to such consolidation, merger, sale, transfer, capital
reorganization or reclassification, assuming such holder of Common Stock of the
Company (A) is not an entity with which the Company consolidated or into which
the Company merged or which merged into the Company or to which such sale or
transfer was made, as the case may be ("constituent entity"), or an affiliate of
a constituent entity, and (B) failed to exercise his or her rights of election,
if any, as to the kind or amount of securities, cash and other property
receivable upon such consolidation, merger, sale or transfer (provided that if
the kind or amount of securities, cash and other property receivable upon such
consolidation, merger, sale or transfer is not the same for each share of Common
Stock of the Company held immediately prior to such consolidation, merger, sale
or transfer by other than a constituent entity or an affiliate thereof and in
respect of which such rights or election shall not have been exercised
("non-electing share"), then for the purpose of this Section 8.2 the kind and
amount of securities, cash and other property receivable upon such
consolidation, merger, sale or transfer by each non-electing share shall be
deemed to be the kind and amount so receivable per share by a plurality of the
non-electing shares). If necessary, appropriate adjustment shall be made in the
application of the provision set forth herein with respect to the rights and
interests thereafter of the holder of Warrants, to the end that the provisions
set forth herein shall thereafter correspondingly be made applicable, as nearly
as may reasonably be, in relation to any shares of stock or other securities or
property thereafter deliverable on the exercise of the Warrants. The above
provisions shall similarly apply to successive consolidations, mergers, sales,
transfers, capital reorganizations and reclassifications. The Company shall not
effect any such consolidation, merger, sale or transfer unless prior to or
simultaneously with the consummation thereof the successor company or entity (if
other than the Company) resulting from such consolidation, merger, sale or
transfer assumes, by written instrument, the obligation to deliver to the holder
of Warrants such shares of stock,

<PAGE>

securities or assets as, in accordance with the foregoing provision, such holder
may be entitled to receive under this Section 8.2.

         8.3 STATEMENT OF WARRANTS. Irrespective of any adjustments in the
Warrant Price of the number or kind of shares purchasable upon the exercise of
this Warrant, this Warrant certificate or certificates hereafter issued may
continue to express the same price and number and kind of shares as are stated
in this Warrant.

         SECTION 9. FRACTIONAL SHARES. Any fractional shares of Common Stock
issuable upon exercise of the Warrants shall be rounded to the nearest whole
share or, at the election of the Company, the Company shall pay the holder
thereof an amount in cash equal to the closing bid price thereof. Whether or not
fractional shares are issuable upon exercise shall be determined on the basis of
the total number of Warrants the holder is at the time exercising and the number
of shares of Common Stock issuable upon such exercise.

         SECTION 10. NO RIGHTS AS STOCKHOLDERS: NOTICES TO WARRANTHOLDERS.
Nothing contained in this Warrant shall be construed as conferring upon the
Warrantholder or its transferees any rights as a stockholder of the Company,
including the right to vote, receive dividends, consent or receive notices as a
stockholder with respect to any meeting of stockholders for the election of
directors of the Company or any other matter. If, however, at any time prior to
the Expiration Time and prior to the exercise of this Warrant, any of the
following events shall occur:

         (a) any action which would require an adjustment pursuant to Section
8.1; or

         (b) a dissolution, liquidation or winding up of the Company or any
consolidation, merger or sale of its property, assets and business as an
entirety; then in any one or more of said events, the Company shall give notice
in writing of such event to the Warrantholder at least ten (10) days prior to
the date fixed as a record date or the date of closing the transfer books for
the determination of the shareholders entitled to any relevant dividend,
distribution, subscription rights, or other rights or for the effective date of
any dissolution, liquidation of winding up or any merger, consolidation, or sale
of substantially all assets, but failure to mail or receive such notice or any
defect therein or in the mailing thereof shall not affect the validity of any
such action taken. Such notice shall specify such record date or the effective
date, as the case may be.

         SECTION 11. MISCELLANEOUS.

         (a) BENEFITS OF THIS AGREEMENT. Nothing in this Warrant shall be
construed to give to any person or corporation other than the Company and the
Warrantholder any legal or equitable right, remedy or claim under this Warrant,
and this Warrant shall be for the sole and exclusive benefit of the Company and
the Warrantholder.

         (b) RIGHTS CUMULATIVE; WAIVERS. The rights of each of the parties under
this Warrant are cumulative. The rights of each of the parties hereunder shall
not be capable of being waived or varied other than by an express waiver or
variation in writing. Any failure to exercise or any delay in exercising any of
such rights shall not operate as a waiver or variation of that or

<PAGE>

any other such right. Any defective or partial exercise of any of such rights
shall not preclude any other or further exercise of that or any other such
right. No act or course of conduct or negotiation on the part of any party shall
in any way preclude such party from exercising any such right or constitute a
suspension or any variation of any such right.

         (c) BENEFIT; SUCCESSORS BOUND. This Warrant and the terms, covenants,
conditions, provisions, obligations, undertakings, rights, and benefits hereof,
shall be binding upon, and shall inure to the benefit of, the parties hereto and
their heirs, executors, administrators, representatives, successors, and
permitted assigns.

         (d) ENTIRE AGREEMENT. This Warrant contains the entire agreement
between the parties with respect to the subject matter hereof. There are no
promises, agreements, conditions, undertakings, understandings, warranties,
covenants or representations, oral or written, express or implied, between them
with respect to this Warrant or the matters described in this Warrant, except as
set forth in this Warrant. Any such negotiations, promises, or understandings
shall not be used to interpret or constitute this Warrant.

         (e) ASSIGNMENT. This Warrant may be assigned if the Assignment of
Warrant, attached as Exhibit B to this Warrant, is properly completed, executed
and delivered to the Company.

         (f) AMENDMENT. This Warrant may be amended only by an instrument in
writing executed by the parties hereto.

         (g) SEVERABILITY. Each part of this Warrant is intended to be
severable. In the event that any provision of this Warrant is found by any court
or other authority of competent jurisdiction to be illegal or unenforceable,
such provision shall be severed or modified to the extent necessary to render it
enforceable and as so severed or modified, this Warrant shall continue in full
force and effect.

         (h) NOTICES. Notices required or permitted to be given hereunder shall
be in writing and shall be deemed to be sufficiently given when personally
