                         COMMON STOCK ADJUSTMENT WARRANT

No. AW1

              To Receive Shares of $.001 Par Value Common Stock of

                             CONSTELLATION 3D, INC.

     THIS CERTIFIES that, for value received, Halifax Fund, L.P. (the
"Investor") is entitled, upon the terms, at the times and subject to the
conditions hereinafter set forth, at any time after the termination of the
Adjustment Period (as defined herein) but prior to 5:00 p.m. New York City time
on August 23, 2005 (the "Termination Date"), to subscribe for and receive from
time to time from CONSTELLATION 3D, INC., a Florida corporation (the "Company"),
all or any portion of an aggregate number of shares of Common Stock of the
Company determined pursuant to Section 3 hereof (the "Adjustment Shares"). The
"Exercise Price" is $0. The number of shares for which the Adjustment Warrant is
exercisable shall be subject to adjustment as provided herein. This Adjustment
Warrant is being issued in connection with the Common Stock Investment Agreement
dated as of August 23, 2000 (the "Purchase Agreement") entered into by the
Company and the Investor. Any capitalized terms used but not defined in this
Adjustment Warrant shall have the meaning specified in the Purchase Agreement.

1.   Title of Adjustment Warrant. Prior to the expiration hereof and subject to
     compliance with applicable laws, this Adjustment Warrant and all rights
     hereunder are transferable, in whole or in respect of the right to receive
     any part of the Adjustment Shares, at the office or agency of the Company
     by the holder hereof in person or by duly authorized attorney, upon
     surrender of this Adjustment Warrant together with (a) the Assignment Form
     annexed hereto properly endorsed, and (b) any other documentation
     reasonably necessary to satisfy the Company that such transfer is in
     compliance with all applicable securities laws.

2.   Authorization of Shares. The Company covenants that all shares of Common
     Stock which may be issued upon the exercise from time to time of rights
     represented by this Adjustment Warrant, upon exercise of the rights
     represented by this Adjustment Warrant, will be duly authorized, validly
     issued, fully paid and nonassessable and free from all taxes, liens and
     charges in respect of the issue thereof (other than taxes in respect of any
     transfer occurring contemporaneously with such issue or otherwise specified
     herein).

3.   Exercise of Adjustment Warrant for Adjustment Shares.

(a)  Definitions.

     Subject to Section 3(e), "Adjustment Period" means the period starting 15
     Trading Days after the day on which a registration statement covering the
     Initial Shares is first declared effective by the SEC and ending on and
     including the 50th consecutive Trading Day thereafter. For the avoidance of
     doubt, the Adjustment Period with respect to an Adjustment Warrant issued
     in connection with the exercise of an Optional Warrant shall be the same
     period in time as the Adjustment Period with respect to the Adjustment
     Warrants issued in connection with the sale of the Initial Shares, even if
     the Adjustment Period has ended prior to the exercise of such Optional
     Warrant.

     "Adjusted Share Purchase Price" means 115% of the Share Purchase Price. The
     Adjusted Share Purchase Price shall be appropriately adjusted to reflect
     stock splits, reverse stock splits, stock dividends, recapitalizations,
     etc.

     "Average Price" means the average of the 20 lowest daily trades for a share
     of Common Stock during the Adjustment Period.

     "Effective Registration" shall have the meaning specified in the Purchase
     Agreement.

     "Principal Market" shall have the meaning specified in the Purchase
     Agreement.

(b)  The number of Adjustment Shares deliverable will be calculated in
     accordance with Section 3(c). No shares will be due pursuant to Section
     3(c) unless the Average Price is less than the Adjusted Share Purchase
     Price.

(c)  Adjustment Share Calculations. Subject to Sections 3(e) and (f), the number
     of Adjustment Shares (if any) issuable in respect of the Adjustment Period
     shall be calculated immediately following the close of trading of the
     Principal Market on the final Trading Day of the Adjustment Period, using
     the following formula:

     # of Adjustment Shares = ($5,750,000 / Average Price) - # of Initial Shares

     The number of Initial Shares used in the above calculation shall be
     appropriately adjusted for any stock slit, reverse stock split, stock
     dividend, recapitalization, etc. Promptly after performing the calculations
     pursuant to Section 3(c), the Company shall deliver its written
     calculations to the Investor by facsimile.

                                        2
<PAGE>

     If this Adjustment Warrant was issued to the Investor pursuant to the
     exercise of an Optional Warrant, the term "Initial Shares" as used in this
     Adjustment Warrant shall be deemed to mean the Optional Warrant Shares
     received upon such exercise of such Optional Warrant.

(d)  Exercise of Adjustment Warrant. Exercise of the rights represented by this
     Adjustment Warrant may be made at any time or times, in whole or in part,
     after the termination of the Adjustment Period and prior to 5:00 p.m. New
     York City time on the Termination Date, by the surrender on any business
     day of this Adjustment Warrant and a Notice of Exercise in the form annexed
     hereto duly completed and executed, at the principal office of the Company
     (or such other office or agency of the Company as it may designate by
     notice in writing to the registered holder hereof at the address of such
     holder appearing on the books of the Company); whereupon the holder of this
     Adjustment Warrant shall be entitled to receive a certificate for the
     number of Adjustment Shares for which this Adjustment Warrant has been so
     exercised. Certificates for Adjustment Shares shall be delivered to the
     holder hereof within three (3) Trading Days after the date on which this
     Adjustment Warrant shall have been exercised as aforesaid (such event being
     a "Fill-Up Closing"). An exercise of this Adjustment Warrant shall be
     deemed for all purposes a "cashless" exercise.

(e)  Effective Registration During Stock Adjustment Period.

                  (i) If at any time during the Adjustment Period there shall be
     a lack of Effective Registration, the Investor (as to itself only) may at
     its option either (x) waive the lack of Effective Registration, in which
     case the Adjustment Period will continue uninterrupted with respect to the
     Investor in accordance with the other provisions of this Section 3, or (y)
     by written notice to the Company (delivered no later than 24 hours after
     actually receiving written notification from the Company of such lack of
     Effective Registration) elect to suspend such Adjustment Period with
     respect to itself only (a "Suspension Notice").

                  (ii) If the Investor elects pursuant to subsection (i) above
     to suspend a particular Adjustment Period and Effective Registration is
     subsequently re-established either before or after the scheduled end of the
     Adjustment Period, then the Investor may, at its option, elect (x) to treat
     the Adjustment Period as tolled for the duration (however long) of the lack
     of Effective Registration, such that the first full day of Effective
     Registration following delivery of the Suspension Notice shall be treated
     as and deemed to be the next day of the tolled Adjustment Period, (y) to
     treat the Adjustment Period as having never commenced, such that the first
     full day of Effective Registration following delivery of the Suspension
     Notice shall be treated as and deemed to be the first day of the Adjustment
     Period, or (z) to treat the Adjustment Period as having been extended by
     such number of days that is equal to the duration of the lack of Effective
     Registration. The Investor shall have two (2) Trading Days after receiving
     written notice from the Company of the re-establishment of Effective
     Registration to make such election.

(f)  Effective Registration as of Fill-Up Closing. If there is not Effective
     Registration on the date of a Fill-Up Closing, then the Investor shall have
     the option (as to itself only) but not the obligation to receive from the
     Company, in lieu of the Adjustment Shares otherwise deliverable, an amount

                                       3
<PAGE>

     in immediately available funds equal to the product of (i) the highest
     closing bid price of the Common Stock on the Principal Market from the
     final Trading Day of the Adjustment Period through and including the
     Trading Day immediately prior to such Fill-Up Closing and (ii) the number
     of Adjustment Shares the Company otherwise would be obligated to deliver to
     such Investor at such Fill-Up Closing.

(g)  Remedies. If the Company fails to deliver the specified number of
     Adjustment Shares to the Investor within 10 Trading Days of the time and at
     the place specified herein, then the Investor may, without reducing its
     other rights at law or in equity, compel the Company to repurchase all or a
     part of its Securities (including the number of Adjustment Shares which,
     without regard to Effective Registration, should have been delivered by the
     Company) at the applicable Premium Redemption Price (as defined and
     specified in the Registration Rights Agreement).

(h)  Adjustments. The number of Adjustment Shares shall be appropriately
     adjusted to reflect any stock split, reverse stock split, stock dividend,
     recapitalization or similar event so that the Investor receives the same
     economically equivalent value of Adjustment Shares as it would in the
     absence of such event.

(i)  Short Sales. The Investor agrees that prior to expiration of the Adjustment
     Period, it will not engage in short sales of Common Shares with the intent
     of lowering the market price of such shares. The fact that the market price
     of the Common Shares declines contemporaneously with short sales effected
     by the Investor shall not be deemed a presumption that the Investor had the
     intent of so lowering the market price.

(j)  Miscellaneous. The Adjustment Shares shall upon delivery to the Investor be
     fully-paid, nonassessable, shares of Common Stock, free and clear of all
     liens and encumbrances and duly eligible for trading on each exchange and
     market on which shares of Common Stock are then traded.

4.   Non-Certificated Shares, In lieu of delivering physical certificates
     representing the Adjustment Shares, provided the Company's transfer agent
     is participating in the Depository Trust Company ("DTC") Fast Automated
     Securities Transfer ("FAST") program, upon request of the Adjustment
     Warrant holder, the Company shall use its best efforts to cause its
     transfer agent to electronically transmit the Adjustment Shares to the
     Adjustment Warrant holder by crediting the account of the Adjustment
     Warrant holder's prime broker with DTC through its Deposit Withdrawal Agent
     Commission ("DWAC") system. The time periods for delivery described in the
     immediately preceding paragraph shall apply to the electronic transmittals
     described herein.

     The term "Trading Day" means (x) if the Common Stock is listed on the New
     York Stock Exchange or the American Stock Exchange, a day on which there is
     trading on such stock exchange, or (y) if the Common Stock is not listed on
     either of such stock exchanges but sale prices of the Common Stock are
     reported on an automated quotation system, a day on which trading is
     reported on the principal automated quotation system on which sales of the

                                       4
<PAGE>

     Common Stock are reported, or (z) if the foregoing provisions are
     inapplicable, a day on which quotations are reported by National Quotation
     Bureau Incorporated.

5.   No Fractional Shares or Scrip. No fractional shares or scrip representing
     fractional shares shall be issued upon the issuance of the Adjustment
     Shares

6.   Charges, Taxes and Expenses. Issuance of certificates for shares of Common
     Stock upon the exercise of this Adjustment Warrant shall be made without
     charge to the holder hereof for any issue or transfer tax or other
     incidental expense in respect of the issuance of such certificate, all of
     which taxes and expenses shall be paid by the Company, and such
     certificates shall be issued in the name of the holder of this Adjustment
     Warrant or in such name or names as may be directed by the holder of this
     Adjustment Warrant; provided, however, that in the event certificates for
     shares of Common Stock are to be issued in a name other than the name of
     the holder of this Adjustment Warrant, this Adjustment Warrant when
     surrendered for exercise shall be accompanied by the Assignment Form
     attached hereto duly executed by the holder hereof; and provided further,
     that the Company shall not be required to pay any tax or taxes which may be
     payable in respect of any transfer involved in the issuance of any
     Adjustment Warrant certificates or any certificates for the Adjustment
     Shares other than the issuance of a Adjustment Warrant certificate to the
     Investor in connection with the Investor's surrender of a Adjustment
     Warrant certificate upon the exercise of less than all of the Adjustment
     Warrants evidenced thereby, 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.

7.   Closing of Books. The Company will at no time close its shareholder books
     or records in any manner which interferes with the timely exercise of this
     Adjustment Warrant.

8.   No Rights as Shareholder until Exercise. Subject to Section 13 of this
     Adjustment Warrant and the provisions of any other written agreement
     between the Company and the Investor, the Investor shall not be entitled to
     vote or receive dividends or be deemed the holder of Adjustment Shares or
     any other securities of the Company that may at any time be issuable on the
     exercise hereof for any purpose, nor shall anything contained herein be
     construed to confer upon the Investor, as such, any of the rights of a
     stockholder of the Company or any right to vote for the election of
     directors or upon any matter submitted to stockholders at any meeting
     thereof, or to give or withhold consent to any corporate action (whether
     upon any recapitalization, issuance of stock, reclassification of stock,
     change of par value, or change of stock to no par value, consolidation,
     merger, conveyance or otherwise) or to receive notice of meetings, or to
     receive dividends or subscription rights or otherwise until the Adjustment
     Warrant shall have been exercised as provided herein. However, at the time
     of the exercise of this Adjustment Warrant pursuant to Section 3 hereof,
     the Adjustment Shares received hereunder shall be deemed to be issued to
     such holder as the record owner of such shares as of the close of business
     on the date on which this Adjustment Warrant shall have been exercised.

                                       5

9.   Assignment and Transfer of Adjustment Warrant. This Adjustment Warrant may
     be assigned in whole or in part by the surrender of this Adjustment Warrant
     and the Assignment Form annexed hereto duly executed at the office of the
     Company (or such other office or agency of the Company as it may designate
     by notice in writing to the registered holder hereof at the address of such
     holder appearing on the books of the Company); provided, however, that this
     Adjustment Warrant may not be resold or otherwise transferred except (i) in
     a transaction registered under the Securities Act of 1933, as amended (the
     "Act"), or (ii) in a transaction pursuant to an exemption, if available,
     from registration under the Act and whereby, if requested by the Company,
     an opinion of counsel reasonably satisfactory to the Company is obtained by
     the holder of this Adjustment Warrant to the effect that the transaction is
     so exempt.

10.  Loss, Theft, Destruction or Mutilation of Adjustment Warrant. Upon receipt
     by the Company of evidence reasonably satisfactory to it of the loss,
     theft, destruction or mutilation of any Adjustment Warrant or stock
     certificate representing the Adjustment Shares, and in case of loss, theft
     or destruction, of indemnity reasonably satisfactory to it, and upon
     reimbursement to the Company of all reasonable expenses incidental thereto.
     Upon surrender and cancellation of such Adjustment Warrant or stock
     certificate, if mutilated, the Company will make and deliver a new
     Adjustment Warrant or stock certificate of like tenor and dated as of such
     cancellation, in lieu of this Adjustment Warrant or stock certificate.

11.  Saturdays, Sundays, Holidays, etc. If the last or appointed day for the
     taking of any action or the expiration of any right required or granted
     herein shall be a Saturday, Sunday or a legal holiday, then such action may
     be taken or such right may be exercised on the next succeeding day not a
     legal holiday.

12.  Effect of Certain Events. If at any time after the date hereof there shall
     be a merger or consolidation of the Company with or into, or a transfer of
     all or substantially all of the assets of the Company to, another entity
     (collectively, a "Sale or Merger Transaction"), the holder of this
     Adjustment Warrant shall have the right thereafter to purchase, by exercise
     of this Adjustment Warrant, the kind and amount of cash, shares and other
     securities and property which it would have owned or have been entitled to
     receive after the happening of such transaction had this Adjustment Warrant
     been exercised immediately prior thereto, subject to further adjustment as
     provided in Section 13. Notwithstanding the above, a Sale or Merger
     Transaction shall not be deemed to occur in the event the Company is the
     acquiring entity in connection with an acquisition by the Company.

13.  Adjustment of Number of Adjustment Warrant Shares. The number of and kind
     of securities purchasable upon exercise of this Adjustment Warrant shall be
     subject to adjustment from time to time as follows:

(a)  Subdivisions, Combinations and other Issuances. If the Company shall at any
     time after the date hereof but prior to the expiration of this Adjustment
     Warrant subdivide its outstanding securities as to which purchase rights
     under this Adjustment Warrant exist, by split-up, spin-off, or otherwise,

                                       6
<PAGE>

     or combine its outstanding securities as to which purchase rights under
     this Adjustment Warrant exist, the number of Adjustment Shares as to which
     this Adjustment Warrant is exercisable as of the date of such subdivision,
     split-up, spin-off or combination shall forthwith be proportionately
     increased in the case of a subdivision, or proportionately decreased in the
     case of a combination.

(b)  Stock Dividend. If at any time after the date hereof the Company declares a
     dividend or other distribution on Common Stock payable in Common Stock or
     other securities or rights convertible into Common Stock ("Common Stock
     Equivalents") without payment of any consideration by holders of Common
     Stock for the additional shares of Common Stock or the Common Stock
     Equivalents (including the additional shares of Common Stock issuable upon
     exercise or conversion thereof), then the number of shares of Common Stock
     for which this Adjustment Warrant may be exercised shall be increased as of
     the record date (or the date of such dividend distribution if no record
     date is set) for determining which holders of Common Stock shall be
     entitled to receive such dividends, in proportion to the increase in the
     number of outstanding shares (and shares of Common Stock issuable upon
     conversion of all such securities convertible into Common Stock) of Common
     Stock as a result of such dividend.

(c)  Other Distributions. If at any time after the date hereof the Company
     distributes to holders of Common Stock, other than as part of its
     dissolution, liquidation or the winding up of its affairs, any shares of
     its capital stock, any evidence of indebtedness or any of its assets (other
     than Common Stock), then the number of Adjustment Shares for which this
     Adjustment Warrant is exercisable shall be increased to equal: (i) the
     number of Adjustment Shares for which this Adjustment Warrant is
     exercisable immediately prior to such event, (ii) multiplied by a fraction,
     (A) the numerator of which shall be the Fair Market Value (as defined
     below) per share of Common Stock on the record date for the dividend or
     distribution, and (B) the denominator of which shall be the Fair Market
     Value price per share of Common Stock on the record date for the dividend
     or distribution minus the amount allocable to one share of Common Stock of
     the value (as jointly determined in good faith by the Board of Directors of
     the Company and the Adjustment Warrant holder) of any and all such
     evidences of indebtedness, shares of capital stock, other securities or
     property, so distributed. In lieu of such change to the number of
     Adjustment Shares for which this Adjustment Warrant is exercisable, the
     Investor (as to itself only) may elect, in its sole discretion, to
     participate in such distribution and receive the shares of capital stock,
     evidence of indebtedness or other assets on an "as exercised" basis as if
     the Adjustment Warrant had been exercised in full for Adjustment Shares as
     of the record date for such distribution, without regard to the
     restrictions contained in Section 14.

     For purposes of this Adjustment Warrant, "Fair Market Value" shall equal
     the 10 Trading Day average closing trading price of the Common Stock on the
     Principal Market for the 10 Trading Days preceding the date of
     determination or, if the Common Stock is not listed or admitted to trading
     on any Principal Market, the average of the closing bid and asked prices on
     the over-the-counter market as furnished by any New York Stock Exchange
     member firm reasonably selected from time to time by the Company for that

                                       7
<PAGE>

     purpose and reasonably acceptable to the Holder, or, if the Common Stock is
     not listed or admitted to trading on the Principal Market or traded
     over-the-counter and the average price cannot be determined as contemplated
     above, the Fair Market Value of the Common Stock shall be as reasonably
     determined in good faith by the Company's Board of Directors with the
     concurrence of the Holder.

(d)  Merger. The Company will not merge or consolidate with or into any other
     corporation, or sell or otherwise transfer its property, assets and
     business substantially as an entirety to another corporation, unless the
     corporation resulting from such merger or consolidation (if not the
     Company), or such transferee corporation, as the case may be, shall
     expressly assume in writing the due and punctual performance and observance
     of each and every covenant and condition of this Adjustment Warrant to be
     performed and observed by the Company.

(e)  Reclassification, etc. If at any time after the date hereof there shall be
     a reorganization or reclassification of the securities as to which purchase
     rights under this Adjustment Warrant exist into the same or a different
     number of securities of any other class or classes, then the Adjustment
     Warrant Holder shall thereafter be entitled to receive upon exercise of
     this Adjustment Warrant, during the period specified herein, the number of
     shares or other securities or property resulting from such reorganization
     or reclassification, which would have been received by the Adjustment
     Warrant Holder for the shares of stock subject to this Adjustment Warrant
     had this Adjustment Warrant at such time been exercised.

14.  9.99% Limitation.

(a)  Notwithstanding anything to the contrary contained herein, the number of
     shares of Common Stock that may be acquired by the holder upon exercise
     pursuant to the terms hereof shall not exceed a number that, when added to
     the total number of shares of Common Stock deemed beneficially owned by
     such holder (other than by virtue of the ownership of securities or rights
     to acquire securities (including the Warrants) that have limitations on the
     holder's right to convert, exercise or purchase similar to the limitation
     set forth herein), together with all shares of Common Stock deemed
     beneficially owned (other than by virtue of the ownership of securities or
     rights to acquire securities that have limitations on the right to convert,
     exercise or purchase similar to the limitation set forth herein) by the
     holder's "affiliates" (as defined Rule 144 of the Act) ("Aggregation
     Parties") that would be aggregated for purposes of determining whether a
     group under Section 13(d) of the Securities Exchange Act of 1934, as
     amended, exists, would exceed 9.99% of the total issued and outstanding
     shares of the Company's Common Stock (the "Restricted Ownership
     Percentage"). Each holder shall have the right (w) at any time and from
     time to time to reduce its Restricted Ownership Percentage immediately upon
     notice to the Company and (x) at any time and from time to time, to
     increase its Restricted Ownership Percentage immediately in the event of
     the announcement as pending or planned of an event of:

                                       8
<PAGE>

                  (i) any consolidation or merger of the Company with or into
     any other corporation or other entity or person (whether or not the Company
     is the surviving corporation), or any other corporate reorganization or
     transaction or series of related transactions in which in excess of 50% of
     the Company's voting power is transferred through a merger, consolidation,
     tender offer or similar transaction,

                  (ii) any person (as defined in Section 13(d) of the Exchange
     Act), together with its affiliates and associates (as such terms are
     defined in Rule 405 under the 1933 Act), beneficially owns or is deemed to
     beneficially own (as described in Rule 13d-3 under the Exchange Act without
     regard to the 60-day exercise period) in excess of 50% of the Company's
     voting power,

                  (iii) there is a replacement of more than one-half of the
     members of the Company's Board of Directors which is not approved by those
     individuals who are members of the Company's Board of Directors on the date
     thereof, in one or a series of related transactions, or

                  (iv) a sale or transfer of all or substantially all of the
     assets of the Company, determined on a consolidated basis.

(b)  The holder covenants at all times on each day (each such day being referred
     to as a "Covenant Day") as follows: During the balance of such Covenant Day
     and the succeeding sixty-one (61) days (the balance of such Covenant Day
     and the succeeding 61 days being referred to as the "Covenant Period") such
     holder will not acquire shares of Common Stock pursuant to any right
     (including the exercise of the Adjustment Warrant) existing at the
     commencement of the Covenant Period to the extent the number of shares so
     acquired by such holder and its Aggregation Parties (ignoring all
     dispositions) would exceed:

     (x) the Restricted Ownership Percentage of the total number of shares of
         Common Stock outstanding at the commencement of the Covenant Period,

     minus

     (y) the number of shares of Common Stock owned by such holder and its
         Aggregation Parties at the commencement of the Covenant Period.

         A new and independent covenant will be deemed to be given by the holder
     as of each moment of each Covenant Day. No covenant will terminate,
     diminish or modify any other covenant. The holder agrees to comply with
     each such covenant. This Section 14 controls in the case of any conflict
     with any other provision of the Transaction Documents.

         The Company's obligation to issue Shares of Common Stock which would
     exceed such limits referred to in this Section 14 shall be suspended to the
     extent necessary until such time, if any, as shares of Common Stock may be
     issued in compliance with such restrictions.

     be invalid, illegal or unenforceable in any respect under any applicable
     law or rule in any jurisdiction, such invalidity, illegality or
     unenforceability shall not affect the validity, legality or enforceability
     of any other provision of this Adjustment Warrant in such jurisdiction or
     affect the validity, legality or enforceability of any provision in any
     other jurisdiction, but this Adjustment Warrant shall be reformed,
     construed and enforced in such jurisdiction as if such invalid, illegal or

     performance of any of the terms of this Adjustment Warrant, but will at all
     times in good faith assist in the carrying out of all such terms and in the
     taking of all such action as may be necessary or appropriate in order to
     protect the rights of the Adjustment Warrant holder against impairment.

     therefor on such exercise, and (b) will take all such action as may be
     reasonably necessary or appropriate in order that the Company may validly
     and legally issue fully paid and nonassessable Adjustment Shares on the
     exercise of this Adjustment Warrant.

                  NOW, THEREFORE, in consideration of the foregoing premises and
the covenants contained herein and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

                                   ARTICLE I
                    Purchase and Sale of Shares and Warrants
                    ----------------------------------------

         Section 1.1 Issuance of Initial Shares and Warrants. Upon the following
terms and conditions, the Company shall issue and sell to the Investors, and the
Investors, severally, not jointly, shall purchase from the Company, the number
of Initial Shares and Warrants indicated next to the Investors' names on
Schedule I attached hereto.

<PAGE>
         (a) Purchase Price. The purchase price for the Initial Shares and
Warrants to be acquired by each Investor (the "Purchase Price") shall be the
Purchase Price set forth next to each such Investor's name on Schedule I. The

equal ninety percent (90%) of the average of the closing bid prices of a share
of Common Stock on the Principal Market on the 5 Trading Days leading up to and
ending on the day prior to the Closing Date, or $10.15313 (and as such term is
used in this Agreement, it shall be adjusted proportionately for stock splits,
reverse stock splits, stock dividends, recapitalizations, and the like). For
purposes of this Agreement, the term "Principal Market" shall mean the OTC
Bulletin Board or if the Common Stock is not quoted thereon, on such exchange or
market (which for purposes of this Agreement shall mean the New York Stock
Exchange, the American Stock Exchange, the Nasdaq National Market System and the
NASDAQ Small Cap Market) upon which the Common Stock is principally traded or
quoted, and "Trading Day" shall mean (x) if the Common Stock is listed on the
New York Stock Exchange or the American Stock Exchange, a day on which there is
trading on such stock exchange, or (y) if the Common Stock is not listed on
either of such stock exchange but sale prices of the Common Stock are reported
on an automated quotation system, a day on which trading is reported on the
principal automated quotation system on which sales of the Common Stock are
reported, or (z) if the foregoing provisions are inapplicable, a day on which
quotations are reported by National Quotation Bureau Incorporated.

         (b) The Closing.

                  (i) The closing of the purchase and sale of the Initial Shares
         and Warrants (the "Closing") shall take place at the offices of
         Kleinberg, Kaplan, Wolff & Cohen, P.C. ("KKWC"), on the date hereof
         (the "Closing Date").

                  (ii) On the Closing Date, the Company shall deliver to the
         Investors all the Initial Shares, with the number and denomination of
         certificates requested by the Investors, and the Warrants purchased
         hereunder, each registered in the name of each such Investor or its
         nominee. On the Closing Date, each Investor shall deliver its Purchase
         Price by wire transfer, to an account designated in writing by the

         in the Depository Trust Company ("DTC") Fast Automated Securities
         Transfer ("FAST") program, upon request of an Investor, the Company
         shall use its best efforts to cause its transfer agent to
         electronically transmit the Initial Shares to such Investor by
         crediting the account of such Investor's prime broker with DTC through
         its Deposit Withdrawal Agent Commission ("DWAC") system. The time
         periods for delivery described above shall apply to the electronic
         transmittals described herein. In addition, each party shall deliver
         all documents, instruments and writings required to be delivered by
         such party pursuant to this Agreement at or prior to the Closing.
         Additionally, at the Closing the Company shall pay (or Halifax Fund,
         L.P. shall pay for the account of the Company, with such payment being
         credited towards Halifax Fund, L.P.'s payment of its Purchase Price) to
         KKWC its legal fees and disbursements as set forth in Section 3.4.

                                   ARTICLE II
                         Representations and Warranties
                         ------------------------------

     Section 2.1 Representations and Warranties of the Company. The Company
hereby makes the following representations and warranties to the Investors as of
the Closing Date and as of the date of an exercise of the Optional Warrant (with
the Schedules referenced herein updated, as necessary, and delivered to the
Investors prior to the delivery of the Optional Warrant Shares):

         (a) Organization and Qualification; Material Adverse Effect. The
Company is a corporation duly incorporated and existing in good standing under
the laws of the State of Florida and has the requisite corporate power to own
its properties and to carry on its business as now being conducted. The Company
does not have any direct or indirect subsidiaries (defined as any entity of
which the Company owns, directly or indirectly, 50% or more of the equity or
voting power) other than the subsidiaries listed in the Pre-Agreement SEC
Documents (as defined herein). Except where specifically indicated to the
contrary, all references in this Agreement to subsidiaries shall be deemed to
refer to all direct and indirect subsidiaries of the Company. Except where
specifically indicated to the contrary, all references in this Article II to the
Company shall be deemed to refer to the Company and its consolidated
subsidiaries. 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 the nature of the business conducted or property owned by it makes such
qualification necessary other than those in which the failure so to qualify
would not have a Material Adverse Effect. "Material Adverse Effect" means any
adverse effect on the business, operations, properties or financial condition of
the entity with respect to which such term is used and which is (either alone or
together with all other adverse effects) material to such entity and other
entities controlling or controlled by such entity taken as a whole, and any
material adverse effect on the transactions contemplated under this Agreement,
the Registration Rights Agreement or any other agreement or document
contemplated hereby or thereby.

         (b) Authorization; Enforcement. (i) The Company has all requisite
corporate power and authority to enter into and perform this Agreement, the
Warrants and the Registration Rights Agreement (the "Transaction Documents") and
to issue the Initial Shares, the Warrant Shares, the Adjustment Shares, the
Optional Warrant Shares, the Anti-Dilution Shares, the MDP Shares and the
Warrants (collectively, the "Securities") in accordance with the terms 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 the issuance of the Registrable Shares, have been duly
authorized by all necessary corporate action, and no further consent or
authorization of the Company or its Board of Directors (or any committee or
subcommittee thereof) or stockholders is required, (iii) the Transaction
Documents have been duly executed and delivered by the Company and (iv) the
Transaction Documents constitute valid and binding obligations of the Company
enforceable against the Company in accordance with their terms, except as such
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, liquidation or similar laws relating to, or
affecting generally the enforcement of creditors' rights and remedies or by
other equitable principles of general application.

                                      -3-

preferred stock; as of July 31, 2000 there were 51,501,609 shares of Common
Stock and no shares of preferred stock issued and outstanding; and, except as
set forth on Schedule 2.1(c), no shares of Common Stock and no shares of
preferred stock were reserved for issuance to persons other than the Investors.
All of the outstanding shares of the Company's Common Stock and preferred stock
have been validly issued and are fully paid and non-assessable. No shares of
capital stock are entitled to preemptive rights and, except as set forth on
Schedule 2.1(c), there are no outstanding options and outstanding warrants for
shares of Common Stock (excluding the Warrants). Except as set forth on Schedule
2.1(c)(i), there are no other scrip, rights to subscribe to, calls or
commitments of any character whatsoever relating to, or securities or rights
exchangeable for or convertible into, any shares of capital stock of the
Company, or contracts, commitments, understandings, or arrangements by which the
Company is or may become bound to issue additional shares of capital stock of
the Company or options, warrants, scrip, rights to subscribe to, or commitments
to purchase or acquire, any shares, or securities or rights convertible or
exchangeable into shares, of capital stock of the Company. Included as exhibits
to the SEC Documents are a true and correct copy of the Company's Certificate of
Incorporation (the "Charter"), as in effect on the date hereof, and a true and
correct copy of the Company's By-Laws, as in effect on the date hereof (the
"By-Laws").

         (d) Issuance of Registrable Shares. The Registrable Securities are duly
authorized and reserved for issuance and, when issued in accordance with this
Agreement or upon exercise in accordance with the Warrants, the Registrable
Securities, will be validly issued, fully paid and non-assessable, free and
clear of any and all liens, claims and encumbrances, and, subject to the
registration of such shares in accordance with the applicable provisions of the
Securities Act of 1933, as amended (the "Securities Act" or the "Act") and the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), will be
entitled to be quoted and/or listed (as the case may be) on the OTC Bulletin
Board (or the American Stock Exchange, the New York Stock Exchange, Nasdaq Small
Cap Market or the Nasdaq National Market System collectively, the "Approved
Markets"), and the holders of such Registrable Shares shall be entitled to all
rights and preferences then accorded to a holder of Common Stock. The
outstanding shares of freely tradable Common Stock are currently quoted on the
OTC Bulletin Board.

         (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 and the issuance of the Securities
do not and will not (i) result in a violation of the Company's Charter or
By-Laws or (ii) conflict with, or constitute a default (or an event which with
notice or lapse of time or both would become a default) under, or give to others
any rights of termination, amendment, acceleration or cancellation of, any
agreement, indenture, patent, patent license or instrument to which the Company
or any of its subsidiaries is a party (collectively, "Company Agreements"), or
(iii) result in a violation of any federal, state, local or foreign law, rule,
regulation, order, judgment or decree (including federal and state securities
laws and regulations) 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 (other than in the case of clause (i) above) where such

                                      -4-
<PAGE>

violation would not reasonably be expected to have a Material Adverse Effect.
The business of the Company and its direct and indirect subsidiaries is being
conducted in material compliance with (i) its Charter and By-Laws, (ii) all
Company Agreements and (iii) all applicable laws, ordinances or regulations of
any governmental entity, except (other than in the case of clause (i) above)
where such violation would not reasonably be expected to have a Material Adverse
Effect. Except for filings, consents and approvals required under applicable
state and federal securities laws, rules or regulations, or the rules and
regulations of the Approved Markets and covered by the Registration Rights
Agreement, the Company is not required under federal, state, local or foreign
law, rule or regulation to obtain any consent, authorization or order of, or
make any filing or registration with, any court or governmental agency in order
for it to execute, deliver or perform any of its obligations under the
Transaction Documents, or to issue and sell the Securities, except for the
registration provisions provided in the Registration Rights Agreement.

         (f) SEC Documents; No Non-Public Information; Financial Statements. The
Common Stock of the Company is registered pursuant to Section 12(g) of the
Exchange Act and the Company and its subsidiaries have filed all reports,
schedules, forms, statements and other documents required to be filed by it with
the SEC pursuant to the reporting requirements of the Exchange Act, including
all such proxy information, solicitation statement and registration statements,
and any amendments thereto required to have been filed as of the Closing Date
(all of the foregoing including filings incorporated by reference therein being
referred to herein as the "SEC Documents"). The Company has not directly or
indirectly provided, and will not directly or indirectly provide, to the
Investors any material non-public information or any information which,
according to applicable law, rule or regulation, should have been disclosed
publicly by the Company but which has not been so disclosed. As of their
respective dates, the SEC Documents complied in all material respects with the
requirements of the Exchange Act and the rules and regulations of the SEC
promulgated thereunder and other federal, state and local laws, rules and
regulations applicable to such SEC Documents, and none of the SEC Documents
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. The SEC Documents contain all material information concerning the
Company and its subsidiaries, and no event or circumstance has occurred prior to
the date hereof or will have occurred on the Closing Date which would require
the Company to disclose such event or circumstance in order to make the

         (h) Principal Exchange/Market. The principal market on which the Common
Stock is currently quoted is the OTC Bulletin Board.

         (i) No Material Adverse Change. Except as disclosed in the
Pre-Agreement SEC Documents, since December 31, 1999, no Material Adverse Effect
has occurred or exists, and no event or circumstance has occurred that with
notice or the passage of time or both is reasonably likely to result in a
Material Adverse Effect with respect to the Company or its subsidiaries on a
consolidated basis.

         (j) No Undisclosed Liabilities. The Company and its subsidiaries have
no liabilities or obligations not disclosed in the Pre-Agreement SEC Documents
(as defined below), other than those liabilities incurred in the ordinary course
of the Company's or its subsidiaries' respective businesses since December 31,
1999, which liabilities, individually or in the aggregate, do not have a
Material Adverse Effect on the Company or its direct or indirect subsidiaries.

         (k) No Undisclosed Events or Circumstances. To the best knowledge of
the Company, no material event or circumstance has occurred or exists with
respect to the Company or its direct or indirect subsidiaries or their
respective businesses, properties, prospects, operations or financial condition,
which, under applicable law, rule or regulation, requires public disclosure or
announcement by the Company but which has not been so publicly announced or
disclosed.

         (l) No General Solicitation. Neither the Company, nor any of its
affiliates, or, to its knowledge, any person acting on its or their behalf has
engaged in any form of general solicitation or general advertising (within the
meaning of Regulation D under the Securities Act) in connection with the offer

         (m) No Integrated Offering. Neither the Company, nor any of its
affiliates, nor to its knowledge any person acting on its or their behalf has,
directly or indirectly, made any offers or sales of any security or solicited
any offers to buy any security, under circumstances that would require
registration of the Securities.

         The issuance of the Securities to the Investors will not be integrated
with any other issuance of the Company's securities (past, current or future)
which requires stockholder approval under the rules of the NASDAQ National
Market System.

         (n) Form S-1. The Company is eligible to file the Registration
Statement (as defined in the Registration Rights Agreement) on Form S-1 under

         (o) Intellectual Property. The Company and/or its wholly-owned
subsidiaries owns or has licenses to use certain patents, copyrights and
trademarks ("intellectual property") associated with its business. The Company
and its subsidiaries have all intellectual property rights which are needed to
conduct the business of the Company and its subsidiaries as it is now being
conducted or as proposed to be conducted as disclosed in the SEC Documents. The
Company and its subsidiaries have no reason to believe that the material
intellectual property rights which it owns are invalid or unenforceable or that
the use of such intellectual property by the Company or its subsidiaries
infringes upon or conflicts with any right of any third party, and except as
disclosed on Schedule 2.1(o) no director or officer of the Company or any of its
subsidiaries has received notice of any alleged infringement or conflict, which
individually or in the aggregate, would reasonably be expected to have a
Material Adverse Effect if proven true. The Company and its subsidiaries have no
actual knowledge of any infringement of its intellectual property by any third
party.

         (p) Poison Pill Provisions. Neither Company nor its wholly-owned
subsidiaries have a stockholder rights plan. None of the acquisition of the
Securities nor the deemed beneficial ownership of shares of Common Stock prior
to, or the acquisition of such shares pursuant to the exercise of the Warrants
will in any event under any circumstance trigger the poison pill provisions of
any other or subsequently adopted plan or agreement, or a substantially similar
occurrence under any successor or similar plan.

         (q) No Litigation. Except as set forth in the reports or documents
filed at least 5 Trading Days prior to the Closing Date by the Company pursuant
to Section 13(a) or 15(d) of the Exchange Act (the "Pre-Agreement SEC
Documents"), no litigation or claim (including those for unpaid taxes) against
the Company or any of its subsidiaries is pending or, to the Company's
knowledge, threatened, and no other event has occurred, which if determined
adversely could reasonably be expected to have a Material Adverse Effect on the
Company or could reasonably be expected to materially and adversely affect the
transactions contemplated hereby. There is no legal proceeding described in the
Pre-Agreement SEC Documents that could reasonably be expected to have a Material
Adverse Effect on the Company.

         (r) Brokers. The Company has taken no action which would give rise to
any claim by any person, other than The Shemano Group and Koor Underwriters
Ltd., for brokerage commissions, finder's fees or similar payments by the
Company or any Investor relating to this Agreement or the transactions
contemplated hereby. The Company shall be responsible for any payments to all
such brokers.

         (s) Other Investors. Except as set forth on Schedule 2.1(s)(i), there
are no outstanding securities issued by the Company that are entitled to
registration rights under the Act. Except as set forth on Schedule 2.1(s)(ii),
there are no outstanding securities issued by the Company that are directly or
indirectly convertible into, exercisable into, or exchangeable for, shares of
Common Stock of the Company, or that have anti-dilution or similar rights that
would be affected by the issuance of any of the Securities.

         (t) Certain Transactions. Except as disclosed in the Pre-Agreement SEC
Documents and except as disclosed on Schedule 2.1(t), none of the officers,
directors, or key 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) 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 direct and indirect
subsidiaries are engaged. 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 without a
significant increase in cost.

         (v) No Reliance on Investors. The Company acknowledges and agrees that
each Investor is acting solely in the capacity of an arm's length purchaser with
respect to the Transaction Documents and the transactions contemplated hereby
and thereby. The Company further acknowledges that no Investor is acting as a
financial advisor or fiduciary of the Company (or in any similar capacity) with
respect to the Transaction Documents and the performance hereunder and
thereunder and the transactions contemplated hereby and thereby. The Company
further represents to the Investors that the Company's decision to enter into
the Transaction Documents and the performance hereunder and thereunder has been
based solely on the independent evaluation by the Company and its
representatives.

         (w) Foreign Corrupt Practices Act. Neither the Company, nor any
director, officer, agent, employee or other person acting on behalf of the
Company or any subsidiary has, in the course of acting for, or on behalf of, the
Company, directly or indirectly used any corporate funds for any unlawful
contribution, gift, entertainment or other unlawful expenses relating to
political activity; directly or indirectly made any direct or indirect unlawful
payment to any foreign or domestic government or party official or employee from
corporate funds; violated or is in violation of any provision of the U.S.
Foreign Corrupt Practices Act of 1977, as amended, or any similar treaties of
the United States; or directly or indirectly made any bribe, rebate, payoff,
influence payment, kickback or other unlawful payment to any foreign or domestic
government or party official or employee.

         (x) Application of Takeover Protections. The Company and its board of
directors have taken all necessary action, if any, in order to render
inapplicable anti-takeover provision contained in the Company's Certificate of
Incorporation or By-Laws or Florida law which is or could become applicable to
the Investors as a result of the transactions contemplated by the Transaction
Documents, including, without limitation, the Company's issuance of the Common
Stock and the Investors' ownership of Common Stock.

                                      -8-

         (y) Acknowledgement of Dilution. The number of shares of Common Stock
constituting the Initial Shares, Anti-Dilution Shares, MDP Shares, Adjustment
Shares, Optional Warrant Shares and Warrant Shares may increase substantially in
certain circumstances. The Company acknowledges that its obligation to issue
shares of Common Stock in accordance with the Transaction Documents is absolute
and unconditional, regardless of the dilution that such issuance may have on
other shareholders of the Company.

validly existing and in good standing under the laws of the jurisdiction of its
organization and is duly qualified to do business and in good standing in each
jurisdiction in which the nature of the business conducted by it makes such

power and authority to enter into and perform the Transaction Documents and to
purchase the Securities being sold to it hereunder, (ii) the execution and

application.

         (c) No Conflicts. The execution, delivery and performance of the
Transaction Documents and the consummation by such Investor of the transactions
contemplated thereby do not and will not (i) result in a violation of such
Investor's organizational documents, or (ii) conflict with any agreement,
indenture or instrument to which such Investor is a party, or (iii) result in a
material violation of any law, rule, or regulation, or any order, judgment or
decree of any court or governmental agency applicable to such Investor. Such

                  (ii) Risks of Investment. Such Investor acknowledges that the
         Securities have not been registered under the Act. Such Investor is
         familiar with the provisions of Rule 144 and understands that in the
         event all of the applicable requirements of Rule 144 are not satisfied,

         required to hold the Registrable Shares for a significant period of
         time prior to reselling them, subject to the Company successfully
         registering the Registrable Shares pursuant to the Registration Rights
         Agreement. Such Investor is capable of assessing the risks of an
         investment in the Registrable Shares and is fully aware of the economic
         risks thereof.

                  (iii) Investment Representation. Such Investor is purchasing

         Securities in violation of federal or state securities laws and such
         Investor has no present arrangement (whether or not legally binding) to

         however, that by making the representations herein, such Investor does
         not agree to hold the Securities for any minimum or other specific term
         and reserves the right to dispose of the Securities at any time in
         accordance with federal and state securities laws applicable to such
         disposition.

                  (iv) Restricted Securities. Such Investor acknowledges and
         understands that the terms of issuance have not been reviewed by the
         SEC or by any state securities authorities and that the Securities have
         been issued in reliance on the certain exemptions for non-public
         offerings under the Act, which exemptions depend upon, among other
         things, the representations made and information furnished by such
         Investor, including the bona fide nature of such Investor's investment
         intent as expressed above.

                  (v) Ability to Bear Economic Risk. Such Investor is an
         "accredited" investor as defined in Rule 501 of Regulation D, as

                  (vii) Reliance by the Company. Such Investor understands that
         the Securities are being or will be, as the case may be, offered and
         sold and will be issued, in reliance on a transactional exemptions from

         that the Company is relying upon the truth and accuracy of the
         representations, warranties, agreements, acknowledgments and
         understandings of such Investor set forth herein in order to determine
         the applicability of such exemptions and the suitability of such
         Investor to acquire the Securities.

         (e) Brokers. Except for the brokers listed in Section 2.1(r), such
Investor has taken no action which would give rise to any claim by any person

         Section 3.1 Registration and Listing; Effective Registration. Until the
earlier of (i) five (5) years from the Closing Date and (ii) the date on which
the Investors neither hold any Registrable Securities nor have the right to
acquire any Registrable Securities, the Company will cause the Common Stock
issuable upon the exercise of the Warrants to continue at all times to be
registered under Section 12(b) or Section 12(g) of the Exchange Act, will comply
in all respects with its reporting and filing obligations under the Exchange
Act, and will not take any action or file any document (whether or not permitted
by the Exchange Act or the rules thereunder) to terminate or suspend such
reporting and filing obligations. Until the earlier of (i) five (5) years from
the Closing Date and (ii) the date on which the Investors neither hold any
Registrable Securities nor have the right to acquire any Registrable Securities,
the Company shall continue the listing and/or quoting of the Registrable
Securities on the OTC Bulletin Board or one of the other Approved Markets and
comply in all respects with the Company's reporting, filing and other
obligations under the bylaws or rules of the Approved Market on which the
Registrable Securities are listed and/or quoted, as the case may be. The Company
shall cause the Registrable Securities to be quoted on the OTC Bulletin Board no
later than the registration of the Registrable Securities under the Act, and at
all times shall continue such listing(s) and/or quoting on one of the Approved
Markets. As used herein and in the other Transaction Documents, the term
"Effective Registration" shall mean: (i) the Company is in compliance with the
Transaction Documents; (ii) the resale of Registrable Securities (as defined in
the Registration Rights Agreement) is covered by an effective registration
statement and such registration statement is not subject to any suspension or
stop orders; (iii) the resale of such securities may be effected pursuant to a

similar circumstance; (iv) the securities are listed on an Approved Market and
are not subject to any trading suspension; (v) no Interfering Event (as

the Company or any direct or indirect subsidiary of the Company is subject to
any bankruptcy, insolvency or similar proceeding.

         Section 3.2 Warrants on Exercise. Upon any partial exercise by an
Investor (or then holder of the Warrants) of the Warrants, the Company shall
issue and deliver to such Investor (or holder) within 3 Trading Days of the date
on which such Warrants are exercised, a new Warrant or Warrants representing the
number of adjusted Warrant Shares, Adjustment Shares or Optional Warrant Shares,
as the case may be, in accordance with the terms of such Warrants.

         Section 3.3 Replacement Certificates. The certificate(s) representing
the Securities held by any Investor (or then holder) may be exchanged by such
Investor (or such holder) at any time and from time to time for certificates
with different denominations representing an equal aggregate number of

same. The Company will deliver such substitute certificates within 3 trading
days. No service charge will be made for such registration or transfer or
exchange.

     Section 3.4 Expenses. The Company shall pay to KKWC in immediately
available funds, at the Closing and promptly upon receipt of any further
invoices relating to the same, all reasonable legal fees and expenses incurred
by the Investors in connection with the transactions contemplated by this
Agreement, the Registration Rights Agreement and the Warrants. At the Closing,
the Company shall pay the amount due for such fees and expenses (which may
include fees and expenses estimated to be incurred for the completion of the
transaction, including post-closing matters). In the event such amount is
ultimately less than actual fees and expenses, the Company shall promptly pay
such deficiency to KKWC upon receipt of an invoice therefor. In lieu thereof,
Halifax Fund, L.P. may pay such amounts due to KKWC, with the amount of such
payment being credited towards the payment of its Purchase Price.

     Section 3.5 Securities Compliance. The Company shall notify the SEC, in
accordance with their requirements, of the transactions contemplated by
Transaction Documents, and shall take all other necessary action and proceedings
as may be required and permitted by applicable law, rule and regulation, for the

so long as any Warrants remain outstanding, the Company agrees that it shall not
(a) declare or pay any dividends or make any distributions to any holder or
holders of Common Stock (other than dividends payable in Common Stock) in their
capacity as shareholders, or (b) purchase or otherwise acquire for value,
directly or indirectly, any shares of Common Stock or other equity security of
the Company; provided that the Company may purchase or acquire shares of Common
Stock that are hereafter issued to employees pursuant to employment, stock
repurchase or other similar agreements.

with copies of all notices and information, including without limitation notices

     Section 3.9 Notification of Additional Financings; Adjustments. The Company
agrees that until the first anniversary of the Closing Date, the Investors shall
have a right of first refusal with respect to all non-public capital raising
transactions as set forth in this Section 3.9. The Company shall give advance
written notice to the Investors prior to any offer or sale of any of its equity
securities or any securities convertible into or exchangeable or exercisable for
such securities in a non-public capital raising transaction, including, without
limitation, all private placements, equity lines and private financings (each a
"Financing Transaction"). The Investors shall have 10 business days from receipt
of such notice to deliver a written notice to the Company that one or more of
such Investors elects to exercise its right of first refusal. If, subsequent to
the Company giving notice to the Investors hereunder, the terms and conditions
of the proposed Financing Transaction are changed in any way, the Company shall
be required to provide a new notice to the Investors hereunder and the Investors
shall have the right of refusal again to purchase all of the securities in the
offering on such changed terms and conditions as provided hereunder. In such
event, if such other Financing Transaction provides for non-cash consideration,
in whole or in part, from such other potential investor(s), the Investors shall
still have the right to participate in the Financing Transaction as provided
herein, provided that cash or cash equivalents may be substituted by the
Investors for such non-cash consideration. This right of first refusal shall
continue even if the Investors elect not to participate in one or more Financing
Transactions. Notwithstanding anything herein to the contrary, this right of
first refusal shall not apply to issuances of the Company's securities pursuant
to (i) the Company's current or future employee, director or bona fide
consultant options plans and/or compensation arrangements, (ii) strategic
corporate alliances not undertaken principally for financing purposes, and (iii)
revolving or term loans provided to the Company by federal or state chartered
banks or thrifts.

     Section 3.10 Reservation of Stock Issuable Upon Exercise of the Warrants.
The Company shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock, solely for the purpose of effecting the
exercise of the Warrants and the issuance of Anti-Dilution Shares and MDP
Shares, such number of its shares of Common Stock as shall from time to time be
sufficient to effect the full exercise of the Warrants and issuance of the
Anti-Dilution Shares and MDP Shares and if at any time the number of authorized
but unissued shares of Common Stock shall not be sufficient to effect the full
exercise of the Warrants and issuance of the Anti-Dilution Shares and MDP
Shares, the Company will take such corporate action as may, in the opinion of
its counsel, be necessary to increase its authorized but unissued shares of
Common Stock to such number of shares as shall be sufficient for such purposes,
including without limitation engaging in best efforts to obtain the requisite
shareholder approval. Without in any way limiting the foregoing, the Company
agrees to reserve and at all times keep available solely for purposes of the
exercise of the Warrants and the issuance of the Anti-Dilution Shares and MDP
Shares such number of authorized but unissued shares of Common Stock that is at
least equal to 150% of the aggregate shares issuable upon exercise of the
Initial Warrants and the Optional Warrants, plus 300% of the number of Initial
Shares, which numbers shall be appropriately adjusted for any stock split,
reverse split, stock dividend or reclassification of the Common Stock. If the
Company falls below the reserves specified in the immediately preceding sentence
and does not cure such non-compliance within 30 days of its start, then the
Investors will be entitled to the compensatory payments specified in Section
2(b)(i) of the Registration Rights Agreement. If at any time the number of
authorized but unissued shares of Common Stock is not sufficient to effect the
full exercise of the Warrants, the Investors shall be entitled to, inter alia,
the premium price redemption rights provided in the Registration Rights
Agreement.

     Section 3.11 Best Efforts. The parties shall use their best efforts to
satisfy timely each of the conditions described in Article 3 of this Agreement.

     Section 3.12 Limitations on Transfers. The Company shall not contribute or
transfer its assets to any of its subsidiaries, other than a subsidiary that has
delivered its guarantee to the Investors in form and substance satisfactory to
the Investors.

     Section 3.13 Form D; Blue Sky Laws. The Company agrees to file a Form D
with respect to the Securities, as required under Regulation D and to provide a
copy thereof to each Investor promptly after such filing. The Company shall, on
or before the Closing Date, take such action as the Company shall have
reasonably determined is necessary to qualify the applicable Securities for sale
to the Investors at the Closing pursuant to this Agreement under applicable
securities or "blue sky" laws of the states of the United States (or to obtain
an exemption from such qualification), and shall provide evidence of any such
action so taken to each Investor on or prior to the Closing Date.

     Section 3.14 Nasdaq Rule. The Investors shall, in the aggregate, be
entitled to exercise Adjustment Warrants (with respect to the Initial Shares
only) for Adjustment Shares and receive Anti-Dilution Shares resulting in a
total of 10,295,171 shares of Common Stock (19.99% of the Common Stock issued
and outstanding on the date hereof, which number shall be subject to
readjustment for any stock split, stock dividend or reclassification of the
Common Stock) (the "20% Cap"). Each Investor shall be entitled to receive
Adjustment Shares and Anti-Dilution Shares such that, together with its Initial
Shares, it will own such total number of shares of Common Stock equal to such
Investor's pro rata share of the 20% Cap. An Investor shall have the right to
receive cash payments from the Company for all shares of Common Stock that this
Section 3.14 renders the Company incapable of issuing to such Investor
("Deficiency Shares") at the Premium Redemption Price for such Deficiency Shares
(as defined in the Registration Rights Agreement). If an Investor has received
its Adjustment Shares and Anti-Dilution Shares but has not depleted the total
number of pro rata shares allocated to it, its remaining pro rata shares shall
be reallocated amongst the Investors still to receive Adjustment Shares and/or
Anti-Dilution Shares on a pro rata basis. If applicable, the restrictions and
redemption obligations set forth in this Section 3.14 shall cease to apply if
(a) the Company obtains written shareholder approval to issue Common Shares in
excess of the 20% Cap pursuant to Nasdaq Rule 4460 or (b) the Company provides
the Investors with irrevocable written notice, based upon the advice of its
counsel, that any such issuance of Common Shares is not subject to the 20% Cap
pursuant to Nasdaq Rule 4460. The Company will use its best efforts promptly to
obtain either the shareholder approval or the irrevocable notice described in
the preceding sentence and to provide the Investors with a copy of same. Without
limiting the foregoing, the Company shall solicit the aforementioned shareholder
approval at the next shareholders meeting (for whatever purpose it may be
called) which, in any event, shall not be later than December 31, 2000 in which
the Company will solicit the aforementioned shareholder approval, will solicit
proxies in favor of issuing Common Shares in excess of the 20% Cap and will use
its best efforts to have all affiliates of the Company which own or control
shares of Common Stock to vote their shares in favor of such resolution.

herein shall limit any of the Company's other obligations under this Agreement
and the filing of such reports and other documents is required for the
applicable provisions of Rule 144); and

         (c) furnish to each Investor so long as such Investor owns Registrable
Securities, promptly upon request, (i) a written statement by the Company that
it has complied with the reporting requirements of Rule 144, the Act and the
1934 Act, (ii) a copy of the most recent annual or quarterly report of the

                                ----------------

         Each certificate representing the Common Stock issued hereunder shall
be stamped or otherwise imprinted with a legend substantially in the following
form:

         THESE SECURITIES HAVE NOT BEEN REGISTERED FOR OFFER OR SALE UNDER THE
SECURITIES ACT OF 1933 OR ANY STATE SECURITIES LAWS. THEY MAY NOT BE SOLD OR
OFFERED FOR SALE EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER
SAID ACT AND ANY APPLICABLE STATE SECURITIES LAW OR AN APPLICABLE EXEMPTION FROM
SUCH REGISTRATION REQUIREMENTS.

         The Company agrees to reissue within 3 trading days certificates for

certificates without such legend if (i) such Common Stock is registered for
resale under the 1933 Act, (ii) such Common Stock may be sold pursuant to Rule
144, or (iii) such Common Stock is sold to a purchaser or purchasers who (in the
opinion of counsel to the seller or such purchaser(s), in form and substance

1933 Act.

         Nothing herein shall limit the right of any holder to pledge these

                                 ---------------

         (a) In consideration of the Investors' execution and delivery of this
Agreement, the Warrants and the Registration Rights Agreement and in addition to

of their partners, officers, directors, employees, members and direct or
indirect investors and any of the foregoing persons' agents or other

with the transactions contemplated by this Agreement) (collectively, the

claims, losses, costs, penalties, fees, liabilities and damages, and expenses in
connection therewith (irrespective of whether any such Indemnitee is a party to
the action for which indemnification hereunder is sought), and including
reasonable attorneys' fees and disbursements (the "Indemnified Liabilities"),
incurred by any Indemnitee as a result of, or arising out of, or relating to (a)
any misrepresentation or breach of any representation or warranty made by the
Company in the Transaction Documents or any other certificate or document
contemplated hereby or thereby, (b) any breach of any covenant, agreement or
obligation of the Company contained in the Transaction Documents or any other
certificate or document contemplated hereby or thereby, and (c) any cause of
action, suit or claim brought or made against such Indemnitee by a third party
and arising out of or resulting from (i) the execution, delivery, performance,
breach by the Company or enforcement of the Transaction Documents or any other
certificate, instrument or document contemplated hereby or thereby, (ii) any
transaction financed or to be financed in whole or in part, directly or
indirectly, with the proceeds of the issuance of the Securities or (iii) the
status of the Investor or holder of the Securities or Warrants as investors in
the Company, and (d) the enforcement of this Section. Notwithstanding the
foregoing, Indemnified Liabilities shall not include any liability of any
Indemnitee arising solely out of such Indemnitee's willful misconduct or
fraudulent action(s). To the extent that the foregoing undertaking by the
Company may be unenforceable for any reason, the Company shall make the maximum
contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under applicable law. Except as otherwise set
forth herein, the mechanics and procedures with respect to the rights and
obligations under this Article VIII shall be the same as those set forth in

of claims and Company's right to assume the defense of claims.

         (b) In consideration of the Company's execution and delivery of this
Agreement, the Warrants and the Registration Rights Agreement, each Investor,
severally and not jointly, shall defend, protect, indemnify and hold harmless
the Company and all of its officers, directors and employees, and any of the
foregoing persons' agents or other representatives (including, without
limitation, those retained in connection with the transactions contemplated by

hereunder is sought), and including reasonable attorneys' fees and disbursements
(the "Indemnified Liabilities"), incurred by any Indemnitee as a result of, or
arising out of, or relating to (a) any misrepresentation or breach of any
representation or warranty made by such Investor in the Transaction Documents or
any other certificate or document contemplated hereby or thereby, (b) any breach
of any covenant, agreement or obligation of such Investor contained in the
Transaction Documents or any other certificate or document contemplated hereby
or thereby, and (c) the enforcement of this Section. Notwithstanding the
foregoing, Indemnified Liabilities shall not include any liability of any
Indemnitee arising solely out of such Indemnitee's willful misconduct or
fraudulent action(s). To the extent that the foregoing undertaking by an
Investor may be unenforceable for any reason, such Investor shall make the
maximum contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under applicable law. Except as otherwise set
forth herein, the mechanics and procedures with respect to the rights and
obligations under this Article VIII shall be the same as those set forth in
Section 6 (other than Section 6(a)) of the Registration Rights Agreement,
adjusted as applicable. Notwithstanding the above, in no event shall an

                         Adjustments; 9.99% Limitation.
                         ------------------------------

     Section 7.1 Purchase Price Adjustments.

         (a) Required Adjustments. Subject to the exclusions contained in
Section 7.1(f) below, if during the MFN Period (defined below) the Company
issues or sells any shares of Common Stock at a Per Share Selling Price (as
defined below) lower than either (i) the Share Purchase Price, or (ii) at a
discount from Fair Market Value greater than 10%, the Share Purchase Price of
the Initial Shares and the Optional Warrant Shares sold to the Investors
hereunder shall be adjusted downward (the "Adjusted Per Share Purchase Price")
to equal the lower of (x) such lower Per Share Selling Price or (y) the product
of (A) the Share Purchase Price divided by .9 and (B) 1.00 minus the discount
from Fair Market Value (as defined in the Initial Warrant) in such transaction
(expressed as a fraction) and the Investors shall be entitled to receive the
additional shares (the "Anti-Dilution Shares") as provided by Section 7.1(c),
subject to Section 7.1(d). The Company shall give the Investors written notice
of, and issue a press release announcing, any such sale within 24 hours of the
closing of any such sale.

         (b) Definitions.

                  (i) For the purposes of this Section 7.1, the term "Per Share
         Selling Price" shall include the amount actually paid by third parties
         for each share of Common Stock. A sale of shares of Common Stock shall
         include the sale or issuance of rights, options, warrants or
         convertible securities under which the Company is or may become
         obligated to issue shares of Common Stock, and in such circumstances
         the Per Share Selling Price of the Common Stock covered thereby shall
         also include the exercise or conversion price thereof (in addition to
         the consideration received by the Company upon such sale or issuance
         less the fee amount as provided above). In case of any such security
         issued within the MFN Period in a "Variable Rate Transaction" or an
         "MFN Transaction" (each as defined below), the Per Share Selling Price
         shall be deemed to be the lowest conversion or exercise price at which
         such securities are converted or exercised or might have been converted
         or exercised in the case of a Variable Rate Transaction, or the lowest
         adjustment price in the case of an MFN Transaction, over the life of
         such securities. If shares are issued for a consideration other than
         cash, the Per Share Selling Price shall be the fair value of such
         consideration as determined in good faith by independent certified
         public accountants mutually acceptable to the Company and the
         Investors.

                                      -21-
<PAGE>

                  (ii) The term "Variable Rate Transaction" shall mean a
         transaction in which the Company issues or sells (a) any debt or equity
         securities that are convertible into, exchangeable or exercisable for,
         or include the right to receive additional shares of Common Stock
         either (x) at a conversion, exercise or exchange rate or other price
         that is based upon and/or varies with the trading prices of or
         quotations for the Common Stock at any time after the initial issuance
         of such debt or equity securities, or (y) with a fixed conversion,
         exercise or exchange price that is subject to being reset at some
         future date after the initial issuance of such debt or equity security
         or upon the occurrence of specified or contingent events directly or
         indirectly related to the business of the Company or the market for the
         Common Stock (but excluding standard stock split anti-dilution
         provisions), or (b) any securities of the Company pursuant to an
         "equity line" structure which provides for the sale, from time to time,
         of securities of the Company which are registered for resale pursuant
         to the Act.

                  (iii) The term "MFN Transaction" shall mean a transaction in
         which the Company issues or sells any securities in a capital raising
         transaction or series of related transactions (the "New Offering")
         which grants to the investor (the "New Investor") the right to receive
         additional securities based upon future capital raising transactions of
         the Company on terms more favorable than those granted to the New
         Investor in the New Offering.

                  (iv) The term "MFN Period" shall mean, with respect to the
         Initial Shares, the period commencing on the Closing Date and ending on
         the second anniversary of the Closing Date, and with respect to the
         Optional Warrant Shares, the period commencing on the date the Investor
         receives such shares and ending on the second anniversary of such date.

         (c) Adjustment Mechanism. Subject to Section 7.1(d) below, if an
adjustment of the Share Purchase Price is required pursuant to Section 7.1(a),
the Company shall deliver to the Investors within 10 business days of the
closing of the transaction giving rise to the adjustment (as may be adjusted
pursuant to Section 7.1(d) below, the "Delivery Date") each Investor's pro-rata
share of such number of additional shares of Common Stock equal to (i) the
Purchase Price paid by the Investor divided by the Adjusted Per Share Purchase
Price as required under Section 7.1(a), minus (ii) the sum of (x) the total
number of Initial Shares or Optional Warrant Shares, as applicable, and (y)
Anti-Dilution Shares previously delivered to that Investor hereunder with
respect to such shares; provided however, that the Company shall effect such
adjustment in cash, in whole or in part, to the extent required by Section
7.1(d). In the event the Company fails to deliver the additional shares by the
Delivery Date, the Company shall be liable to the Investors for a Monthly Delay
Payment (as defined in the Registration Rights Agreement) with respect to such
additional shares.

         (d) Limitation on Number of Shares.

                  (i) Notwithstanding anything to the contrary contained herein,
         the number of Anti-Dilution Shares and MDP Shares that may be acquired
         by any Investor shall not exceed a number that, when added to the total
         number of shares of Common Stock deemed beneficially owned by such
         Investor (other than by virtue of the ownership of securities or rights
         to acquire securities (including this Section 7.1) that have
         limitations on the Investor's right to convert, exercise or purchase
         similar to the limitation set forth herein), together with all shares
         of Common Stock deemed beneficially owned (other than by virtue of the
         ownership of securities or rights to acquire securities that have
         limitations on the right to convert, exercise or purchase similar to
         the limitation set forth herein) by the holder's "affiliates" (as
         defined in Rule 144) ("Aggregation Parties") that would be aggregated
         for purposes of determining whether a group under Section 13(d) of the
         Securities Exchange Act of 1934 as amended, exists, would exceed 9.99%
         of the total issued and outstanding shares of the Common Stock (the
         "Restricted Ownership Percentage"). Each holder shall have the right
         (w) at any time and from time to time to reduce its Restricted
         Ownership Percentage immediately upon notice to the Company and (x)
         (subject to waiver) at any time and from time to time, to increase its
         Restricted Ownership Percentage immediately in the event of the
         announcement as pending or planned, of a change of control transaction
         (including without limitation a transaction that would result in a
         transfer of more than 50% of the Company's voting power or equity, or a
         transaction that would result in a person or "group" being deemed the
         beneficial owner of 50% or more of the Company's voting power or
         equity).

                  (ii) Each Investor covenants at all times on each day (each
         such day being referred to as a "Covenant Day") as follows: During the
         balance of such Covenant Day and the succeeding sixty-one (61) days
         (the balance of such Covenant Day and the succeeding 61 days being
         referred to as the "Covenant Period") such Investor will not acquire
         shares of Common Stock pursuant to any right (including pursuant to
         this Section 7.1) existing at the commencement of the Covenant Period
         to the extent the number of shares so acquired by such Investor and its
         Aggregation Parties (ignoring all dispositions) would exceed:

                  (x) the Restricted Ownership Percentage of the total number of
                      shares of Common Stock outstanding at the commencement of
                      the Covenant Period, minus

                  (y) the number of shares of Common Stock actually owned by
                      such Investor and its Aggregation Parties at the
                      commencement of the Covenant Period.

                                      -23-

<PAGE>

A new and independent covenant will be deemed to be given by the Investor as of
each moment of each Covenant Day. No covenant will terminate, diminish or modify
any other covenant. The Investor agrees to comply with each such covenant. This
Section 7.1(d)(ii) controls in the case of any conflict with any other provision
of this Agreement or any agreement entered into in connection herewith.

                  (iii) The Company's obligation to issue Common Stock which
         would exceed such limits referred to in this Section 7.1(d) shall be
         suspended to the extent necessary until such time, if any, as shares of
         Common Stock may be issued in compliance with such restrictions.

                  (iv) If by way of any adjustment required by this Section 7.1,
         the Investor would receive a number of shares of Common Stock such that
         the total number of such shares held by the Investor as of the date of
         such adjustment would equal or exceed the Restricted Ownership
         Percentage, then the Company shall not effect the adjustment required
         by this Section only to the extent necessary to avoid causing the
         aforesaid limitation to be exceeded. With respect to such shares of
         Common Stock which may not be issued to an Investor on the Delivery
         Date due to the limitation contained in this paragraph ("Excess
         Shares"), the Delivery Date for such Excess Shares, or any portion
         thereof from time to time as specified by the Investor, shall be
         extended to such date which is 8 calendar days following delivery of
         written notice to the Company from the Investor stating that the Excess
         Shares (or such portion thereof), are no longer subject to the
         limitation contained in this paragraph since such Excess Shares (or
         portion thereof) may be issued without violating the Restricted
         Ownership Percentage.

         (e) Capital Adjustments. In case of any stock split or reverse stock
split, stock dividend, reclassification of the common stock, recapitalization,
merger or consolidation, or like capital adjustment affecting the Common Stock
of the Company, the provisions of Section 7.1 shall be applied in a fair,
equitable and reasonable manner so as to give effect, as nearly as may be, to
the purposes hereof.

         (f) Exclusions. Section 7.1(a) shall not apply to:

                  (i) sales of shares of Common Stock by the Company pursuant to
         the provisions of any existing option, compensation or similar plan or
         agreement heretofore adopted by the Company; provided, that the primary
         purpose of any such plan or agreement is not the raising of capital;

                  (ii) sales of shares of Common Stock by the Company upon
         conversion or exercise of any convertible securities, options or
         warrants outstanding prior to the date hereof; or

                  (iii) sales of shares of Common Stock by the Company (in one
         or more tranches to the same or different purchasers) that, in the
         aggregate, have a fair market value of less than $500,000 at the
         time(s) they are sold.

         (g) Rule 144. The Company agrees to take the position that, for
purposes of determining the holding period under Rule 144 for Anti-Dilution
Shares and MDP Shares, the holding period of such shares shall be tacked to the
holding period of the Initial Shares.
