         time pursuant to the provisions hereof.

         SECTION 2. WARRANTS AND ISSUANCE OF WARRANT CERTIFICATES.

                  (a) A Warrant shall initially entitle the Registered Holder of
         the Warrant Certificate representing such Warrant to purchase one share
         of Common Stock upon the exercise thereof, in accordance with the terms
         hereof, subject to modification and adjustment as provided in Section

                  (c) From time to time, up to the Warrant Expiration Date, the

         (i) those initially issued hereunder, those issued hereunder on any
         subsequent closing of the Private Placement and those issued upon
         exercise of any Placement Agent Option; (ii) those issued on or after
         the Initial Warrant Exercise Date, upon the exercise of fewer than all

         of the Warrants made pursuant to Section 8 hereof, and (b) other
         modifications approved in accordance with Section 15 hereof.

         SECTION 3. FORM AND EXECUTION OF WARRANT CERTIFICATES.

                  (a) The Warrant Certificates for the Warrants, shall be
         substantially in the form annexed hereto as Exhibit A (the provisions
         of which are hereby incorporated herein) and may have such letters,
         numbers or other marks of identification or designation and such
         legends, summaries or endorsements printed, lithographed, engraved or
         typed thereon as the Company may deem appropriate and as are not
         inconsistent with the provisions of this Agreement, or as may be
         required to comply with any law or with any rule or regulation made
         pursuant thereto or with any rule or regulation of any stock exchange
         on which the Warrants may be listed, or to conform to usage. The
         Warrant Certificates shall be dated the date of issuance thereof
         (whether upon initial issuance, transfer, exchange or in lieu of
         mutilated, lost, stolen, or destroyed Warrant Certificates) and issued
         in registered form. The Warrants shall be numbered serially with the
         letters PW.

                  (b) Warrant Certificates shall be executed on behalf of the
         Company by its Chairman of the Board, Chief Executive Officer,
         President or any Vice President and by its Chief Financial Officer,
         Secretary or an Assistant Secretary and shall have imprinted thereon a
         facsimile of the Company's seal. In case any officer of the Company who
         shall have signed any of the Warrant Certificates shall cease to be
         such officer of the Company before the date of issuance of the Warrant

                                      -2-
<PAGE>

         Certificates and delivery thereof, such Warrant Certificates may
         nevertheless be issued and delivered with the same force and effect as
         though the person who signed such Warrant Certificates had not ceased
         to be such officer of the Company. After execution by the Company,
         Warrant Certificates shall be delivered by the Company to the
         Registered Holder.

         SECTION 4. EXERCISE.

                  (a) Each Warrant may be exercised by the Registered Holder
         thereof at any time on or after the Initial Warrant Exercise Date, but
         not after the Warrant Expiration Date, upon the terms and subject to
         the conditions set forth herein and in the applicable Warrant
         Certificate. A Warrant shall be deemed to have been exercised
         immediately prior to the close of business on the Exercise Date and the
         person entitled to receive the securities deliverable upon such
         exercise shall be treated for all purposes as the holder upon exercise
         thereof as of the close of business on the Exercise Date. As soon as
         practicable on or after the Exercise Date the Company shall cause to be
         issued and delivered by the Transfer Agent, to the person or persons
         entitled to receive the same, a certificate or certificates for the
         securities deliverable upon such exercise, (plus a certificate for any
         remaining unexercised Warrants of the Registered Holder).

                  (b) The Board of Directors has approved and determined to
         submit to stockholders a certificate of amendment to the Company's
         Certificate of Incorporation to increase the number of shares of
         authorized Common Stock to 60,000,000 shares (the "Proposed Charter
         Amendment"). It is understood that if the Proposed Charter Amendment is
         not filed with the Secretary of State of Delaware by the Initial
         Warrant Exercise Date, after reserving the number of shares of Common
         Stock issuable upon conversion of the Series B Preferred Stock sold in
         the Private Placement, including the Series B Preferred Stock
         underlying the Placement Agent Option, the Company may not have a
         sufficient number of shares of Common Stock authorized and available
         for issuance upon exercise of this Warrant. Therefore, prior to the
         filing of the Proposed Charter Amendment, a holder of this Warrant
         shall be allowed to exercise this Warrant for only that number of
         shares of Common Stock equal to the product of the number of
         authorized, unissued and unreserved shares of Common Stock on the date
         of exercise multiplied by a fraction, the numerator of which is the
         total number of Warrant Shares issuable upon exercise of the Warrant
         held by such holder and the denominator of which is the total number of
         Warrant Shares issuable upon exercise of the Warrants sold in the
         Private Placement, including the Placement Agent Option.

                  (c) The Registered Holder may, at its option, at any time on
         or after the Initial Warrant Exercise Date, exchange Warrants on a
         cashless basis, in whole or in part (a "Warrant Exchange"), for the
         number of Warrant Shares determined in accordance with this Section
         (4)(c), by surrendering the Warrant Certificate at the principal office
         of the Company, accompanied by a notice stating such Registered
         Holder's intent to effect such exchange, the number of Warrants to be
         exchanged and the date on which the Registered Holder requests that
         such Warrant Exchange occur (the "Notice of Exchange"). The Warrant
         Exchange shall take place on the date specified in the Notice of
         Exchange or, if later, the date the Notice of Exchange is received by
         the Company (the "Exchange Date"). Certificates for the shares issuable
         upon such Warrant Exchange and, if applicable, a new Warrant
         Certificate of like tenor evidencing the balance of the Warrants
         remaining subject to the surrendered Warrant Certificate, shall be
         issued as of the Exchange Date and delivered to the Registered Holder
         within seven (7) days following the Exchange Date. In connection with
         any Warrant Exchange, a Warrant Certificate shall represent the right
         to subscribe for and acquire the number of Warrant Shares (rounded to
         the next highest integer) equal to (i) the number of Warrants specified
         by the Registered Holder in its Notice of Exchange (the "Total Number")
         less (ii) the number of Warrant Shares equal to the quotient obtained
         by dividing (A) the product of the Total Number and the existing
         Exercise Price by (B) the current market price of a share of Common
         Stock. Current market price shall have the meaning set forth Section 11
         hereof, except that for purposes hereof, the date of exercise, as used
         in such Section 11 hereof, shall mean the Exchange Date.

         SECTION 5. RESERVATION OF SHARES; BLUE SKY APPROVALS; PAYMENT OF TAXES.

                  (a) Subject to Section 4(b) above, the Company covenants that
         it will at all times following the Initial Warrant Exercise Date
         reserve and keep available out of its authorized Common Stock, solely
         for the purpose of issue upon exercise of Warrants, such number of

                                      -3-
<PAGE>

         shares of Common Stock as shall then be issuable upon the exercise of
         all outstanding Warrants. The Company covenants that all shares of
         Common Stock which shall be issuable upon exercise of the Warrants and
         payment of the Exercise Price shall, at the time of delivery, be duly
         and validly issued, fully paid, nonassessable and free from all taxes,
         liens and charges with respect to the issue thereof (other than those
         which the Company shall promptly pay or discharge).

                  (b) The Company will use reasonable efforts to obtain
         appropriate approvals or registrations under state "blue sky"
         securities laws with respect to the exercise of the Warrants; provided,
         however, that the Company shall not be obligated to file any general
         consent to service of process or qualify as a foreign corporation in
         any jurisdiction. With respect to any such securities laws, however,
         Warrants may not be exercised by, or shares of Common Stock issued to,
         any Registered Holder in any state in which such exercise would be
         unlawful.

                  (c) The Company shall pay all documentary, stamp or similar
         taxes and other governmental charges that may be imposed with respect
         to the issuance of Warrants, or the issuance, or delivery of any shares
         upon exercise of the Warrants; provided, however, that if the shares of
         Common Stock are to be delivered in a name other than the name of the
         Registered Holder of the Warrant Certificate representing any Warrant
         being exercised, then no such delivery shall be made unless the person
         requesting the same has paid to the Company the amount of transfer
         taxes or charges incident thereto, if any.

         SECTION 6. EXCHANGE AND REGISTRATION OF TRANSFER. Subject to the
restrictions on transfer contained in the Warrant Certificates and the
Subscription Agreement(s) between the Company and each of the investors in the
Private Placement:

                  (a) Warrant Certificates may be exchanged for other Warrant
         Certificates representing an equal aggregate number of Warrants or may
         be transferred in whole or in part. Warrant Certificates to be
         exchanged shall be surrendered to the Company at its Corporate Office,
         and upon satisfaction of the terms and provisions hereof, the Company
         shall execute, issue and deliver in exchange therefor the Warrant
         Certificate or Certificates which the Registered Holder making the
         exchange shall be entitled to receive.

                  (b) The Company shall keep at its office books in which,
         subject to such reasonable regulations as it may prescribe, it shall
         register Warrant Certificates and the transfer thereof in accordance
         with its regular practice. Upon due presentment for registration of
         transfer of any Warrant Certificate at its office, the Company shall
         execute, issue and deliver to the transferee or transferees a new
         Warrant Certificate or Certificates representing an equal aggregate
         number of Warrants of the same tranche. The Company shall also make
         available to Commonwealth for inspection by its agents or employees,
         from time to time as Commonwealth may request, such original books of
         accounts and record (including original Warrant Certificates
         surrendered to the Company upon exercise of Warrants) as may be
         maintained by the Company in connection with the issuance and exercise
         of Warrants hereunder, such inspections to occur at the Company's
         Corporate Office during normal business hours.

                  (c) With respect to all Warrant Certificates presented for
         registration of transfer, or for exchange or exercise, the subscription
         form on the reverse thereof shall be duly endorsed, or be accompanied
         by a written instrument or instruments of transfer and subscription, in
         form satisfactory to the Company, duly executed by the Registered
         Holder or his attorney-in-fact duly authorized in writing.

                  (d) The Company may require payment by such holder of a sum
         sufficient to cover any tax or other governmental charge that may be
         imposed in connection therewith.

                  (e) All Warrant Certificates surrendered for exercise or for
         exchange shall be promptly canceled by the Company and thereafter
         retained by the Company until termination of this Agreement, or, with
         the prior written consent of Commonwealth, disposed of or destroyed.

                  (f) Prior to due presentment for registration of transfer
         thereof, the Company may deem and treat the Registered Holder of any
         Warrant Certificate as the absolute, true and lawful owner thereof and
         of each Warrant represented thereby (notwithstanding any notations of
         ownership or writing thereon made by anyone other than a duly
         authorized officer of the Company) for all purposes and the Company
         shall not be affected by any notice to the contrary, except as
         otherwise expressly provided in Section 7 hereof.

                                      -4-
<PAGE>

         SECTION 7. LOSS OR MUTILATION. Upon receipt by the Company of evidence
satisfactory to it of the ownership of and loss, theft, destruction or
mutilation of any Warrant Certificate and (in case of loss, theft or
destruction) of indemnity satisfactory to them, and (in the case of mutilation)
upon surrender and cancellation thereof, and in the absence of notice to the
Company that the Warrant Certificate has been acquired by a bonafide purchaser,
the Company shall execute and deliver to the Registered Holder in lieu thereof a
new Warrant Certificate of like tenor representing an equal aggregate number of
Warrants. Applicants for a substitute Warrant Certificate shall comply with such
other reasonable regulations and pay such other reasonable charges as the
Company may prescribe.

         SECTION 8. ANTI-DILUTION PROVISIONS. The Exercise Price in effect at
any time and the number and kind of securities purchasable upon the exercise of
the Warrants shall be subject to adjustment from time to time upon the happening
of certain events as follows:

                  (a) In case the Company shall hereafter (i) declare a dividend
         or make a distribution on its outstanding shares of Common Stock in
         shares of Common Stock, (ii) subdivide or reclassify its outstanding
         shares of Common Stock into a greater number of shares, or (iii)
         combine or reclassify its outstanding shares of Common Stock into a
         smaller number of shares, the Exercise Price in effect at the time of
         the record date for such dividend or distribution or of the effective
         date of such subdivision, combination or reclassification shall be
         adjusted so that it shall equal the price determined by multiplying the
         Exercise Price by a fraction, the denominator of which shall be the
         number of shares of Common Stock outstanding after giving effect to
         such action, and the numerator of which shall be the number of shares
         of Common Stock outstanding immediately prior to such action. Such
         adjustment shall be made successively whenever any event listed above
         shall occur.

                  (b) In case the Company shall fix a record date for the
         issuance of rights or warrants to all holders of its Common Stock
         entitling them to subscribe for or purchase shares of Common Stock (or
         securities convertible into Common Stock) at a price (the "Subscription
         Price") (or having a conversion price per share) less than the current
         market price (as defined below) on such record date, the Exercise Price
         shall be adjusted so that the same shall equal the price determined by
         multiplying the Exercise Price in effect immediately prior to the date
         of such issuance by a fraction, the numerator of which shall be the sum
         of the number of shares of Common Stock outstanding on the record date
         mentioned below and the number of additional shares of Common Stock
         which the aggregate offering price of the total number of shares of
         Common Stock so offered (or the aggregate conversion price of the
         convertible securities so offered) would purchase at such current
         market price per share of the Common Stock, and the denominator of
         which shall be the sum of the number of shares of Common Stock
         outstanding on such record date and the number of additional shares of
         Common Stock offered for subscription or purchase (or into which the
         convertible securities so offered are convertible). Such adjustment
         shall be made successively whenever such rights or warrants are issued
         and shall become effective immediately after the record date for the
         determination of shareholders entitled to receive such rights or
         warrants.

                  (c) In case the Company shall hereafter distribute to the
         holders of its Common Stock evidences of its indebtedness or assets
         (excluding cash dividends or distributions and dividends or
         distributions referred to in Subsection (a) above) or subscription
         rights or warrants (excluding those referred to in Subsection (b)
         above), then in each such case the Exercise Price in effect thereafter
         shall be determined by multiplying the Exercise Price in effect
         immediately prior thereto by a fraction, the numerator of which shall
         be the total number of shares of Common Stock outstanding multiplied by
         the current market price per share of Common Stock (as defined below),
         less the fair market value (as determined by the Company's Board of
         Directors) of said assets or evidences of indebtedness so distributed
         or of such rights or warrants, and the denominator of which shall be
         the total number of shares of Common Stock outstanding multiplied by
         such current market price per share of Common Stock. Such adjustment
         shall be made successively whenever such a record date is fixed. Such
         adjustment shall be made whenever any such distribution is made and
         shall become effective immediately after the record date for the
         determination of shareholders entitled to receive such distribution.

                  (d) In case the Company shall hereafter issue shares of its
         Common Stock (excluding shares issued (i) in any of the transactions
         described in Subsection (a) above, (ii) upon exercise of options
         granted to the Company's officers, directors, employees and consultants
         under a plan or plans adopted by the Company's Board of Directors or a
         committee thereof and approved by its shareholders, if such shares
         would otherwise be included in this Subsection (d), (but only to the

                                      -5-
<PAGE>

         extent that the aggregate number of shares excluded by this Subsection
         (d)(ii) does not exceed 15% of the Company's Common Stock outstanding,
         on a fully diluted basis, at the time of any issuance), (iii) upon
         exercise of options, warrants, convertible securities and convertible
         debentures outstanding as of the final closing of the Private
         Placement, (iv) to shareholders of any corporation which merges into
         the Company in proportion to their stock holdings of such corporation
         immediately prior to such merger, upon such merger, (v) in a private
         placement where the Offering Price (as defined below) is at least 75%
         of the current market price, (vi) in a bona fide public offering
         pursuant to a firm commitment underwriting, or (vii) in connection with
         an acquisition of a business or technology which has been approved by a
         majority of the Company's outside directors but only if no adjustment
         is required pursuant to any other specific subsection of this Section 8
         (without regard to Subsection (i) below) with respect to the
         transaction giving rise to such rights) for a consideration per share
         (the "Offering Price") less than the current market price on the date
         of such issuance, the Exercise Price shall be adjusted immediately
         thereafter so that it shall equal the price determined by multiplying
         the Exercise Price in effect immediately prior thereto by a fraction,
         the numerator of which shall be the sum of the number of shares of
         Common Stock outstanding immediately prior to the issuance of such
         additional shares and the number of shares of Common Stock which the
         aggregate consideration received for the issuance of such additional
         shares would purchase at such current market price per share of Common
         Stock, and the denominator of which shall be the number of shares of
         Common Stock outstanding immediately after the issuance of such
         additional shares. Such adjustment shall be made successively whenever
         such an issuance is made.

                  (e) In case the Company shall hereafter issue any securities
         convertible into or exchangeable for its Common Stock (excluding
         securities issued in transactions described in Subsections (b) and (c)
         above or in the exclusions set forth in (d)(i) through (vii) above) for
         a consideration per share of Common Stock (the "Exchange Price")
         initially deliverable upon conversion or exchange of such securities
         (determined as provided in Subsection (g) below) less than the current
         market price on the date of such issuance, the Exercise Price shall be
         adjusted immediately thereafter so that it shall equal the price
         determined by multiplying the Exercise Price in effect immediately
         prior thereto by a fraction, the numerator of which shall be the sum of
         the number of shares of Common Stock outstanding immediately prior to
         the issuance of such securities and the number of shares of Common
         Stock which the aggregate consideration received for such securities
         would purchase at such current market price per share of Common Stock,
         and the denominator of which shall be the sum of the number of shares
         of Common Stock outstanding immediately prior to such issuance and the
         maximum number of shares of Common Stock of the Company deliverable
         upon conversion of or in exchange for such securities at the initial
         conversion or exchange price or rate. Such adjustment shall be made
         successively whenever such an issuance is made.

                  (f) Whenever the Exercise Price payable upon exercise of each
         Warrant is adjusted pursuant to Subsections (a), (b), (c), (d) and (e)
         above or pursuant to subsection (j) below, the number of Warrant Shares
         purchasable upon exercise of each Warrant shall simultaneously be
         adjusted by multiplying the number of Warrant Shares initially issuable
         upon exercise of such Warrant by the Exercise Price in effect on the
         date hereof and dividing the product so obtained by the Exercise Price,
         as adjusted.

                  (g) For purposes of any computation respecting consideration
         received pursuant to Subsections (d) and (e) above and (j) below, the
         following shall apply:

                           (A) in the case of the issuance of shares of Common
                  Stock for cash, the consideration shall be the amount of such
                  cash, provided that in no case shall any deduction be made for
                  any commissions, discounts or other expenses incurred by the
                  Company for any underwriting of the issue or otherwise in
                  connection therewith;

                           (B) in the case of the issuance of shares of Common
                  Stock for a consideration in whole or in part other than cash,
                  the consideration other than cash shall be deemed to be the
                  fair market value thereof as determined in good faith by the
                  Board of Directors of the Company (irrespective of the
                  accounting treatment thereof), whose determination shall be
                  conclusive; and

                           (C) in the case of the issuance of securities
                  convertible into or exchangeable for shares of Common Stock,

                                      -6-
<PAGE>

                  the aggregate consideration received therefor shall be deemed
                  to be the consideration received by the Company for the
                  issuance of such securities plus the additional minimum
                  consideration, if any, to be received by the Company upon the
                  conversion or exchange thereof (the consideration in each case
                  to be determined in the same manner as provided in clauses (A)
                  and (B) of this Subsection (g)). Upon the expiration or
                  termination of any such securities convertible into or
                  exchangeable for shares of Common Stock, the Exercise Price
                  shall be automatically readjusted to the Exercise Price that
                  would have been obtained had such convertible or exchangeable
                  securities not been issued.

                  (h) For the purpose of any computation under Subsection (b),
         (c), (d) and (e) above, the current market price per share of Common
         Stock at any date shall be determined in the manner set forth in
         Section 11 hereof.

                  (i) No adjustment in the Exercise Price shall be required
         unless such adjustment would require an increase or decrease of at
         least five cents ($0.05) in such price; provided, however, that any
         adjustments which by reason of this Subsection (i) are not required to
         be made shall be carried forward and taken into account in any
         subsequent adjustment required to be made hereunder. All calculations
         under this Section 8 shall be made to the nearest cent or to the
         nearest one-hundredth of a share, as the case may be. Anything in this
         Section 8 to the contrary notwithstanding, the Company shall be
         entitled, but shall not be required, to make such changes in the
         Exercise Price, in addition to those required by this Section 8, as it
         shall determine, in its sole discretion, to be advisable in order that
         any dividend or distribution in shares of Common Stock, or any
         subdivision, reclassification or combination of Common Stock, hereafter
         made by the Company shall not result in any Federal income tax
         liability to the holders of Common Stock or securities convertible into
         Common Stock (including Warrants).

                  (j) Notwithstanding the other provisions of this Section 8,

                                    (A) in the event that the Company shall at
                  any time issue securities in transactions of the type
                  described in Subsections (b), (d) and (e) of this Section 8
                  (other than securities issued in transactions described in
                  Subsection (d)(i) through (vii) above) having an Offering
                  Price, Subscription Price or Exchange Price less than the
                  Exercise Price, then the Exercise Price shall be immediately
                  reset to equal such lower Offering Price, Subscription Price
                  or Exchange Price and

                                    (B) no adjustment under Subsections (b), (d)
                  or (e) shall be required for issuances below the current
                  market price if (i) the Offering Price, Subscription Price or
                  Exchange Price, as applicable, is at least 300% of the
                  Exercise Price then in effect and (ii) a registration
                  statement covering the Warrant Shares is in effect and remains
                  in effect for the 90 days after such issuance or Rule 144(k)
                  under the Securities Act of 1933, as amended (the "Act") is
                  available for resale of all of the Warrant Shares.

                  (k) Whenever the Exercise Price is adjusted, as herein
         provided, the Company shall promptly cause a notice setting forth the
         adjusted Exercise Price and adjusted number of Warrant Shares issuable
         upon exercise of each Warrant, and, if requested, information
         describing the transactions giving rise to such adjustments, to be
         mailed to the holders at their last addresses appearing in the registry
         books maintained by the Company pursuant to Section 6(b), and shall
         cause a certified copy thereof to be mailed to its transfer agent, if
         any. The Company may retain a firm of independent certified public
         accountants selected by the Board of Directors (who may be the regular
         accountants employed by the Company) to make any computation required
         by this Section 8, and a certificate signed by such firm shall be
         conclusive evidence of the correctness of such adjustment absent
         manifest error.

                  (l) In the event that at any time, as a result of an
         adjustment made pursuant to this Section 8, a holder of Warrants
         thereafter shall become entitled to receive any securities, other than
         Common Stock, thereafter the number of such other securities so
         receivable upon exercise of a Warrant shall be subject to adjustment
         from time to time in a manner and on terms as nearly equivalent as
         practicable to the provisions with respect to the Common Stock
         contained in Subsections (a) to (j), inclusive above.

                                      -7-
<PAGE>

                  (m) In case of any reorganization, reclassification or change
         of the Common Stock (including any such reorganization,
         reclassification or change in connection with a consolidation or merger
         in which the Company is the continuing entity), or any consolidation of
         the Company with, or merger of the Company with or into, any other
         entity (other than a consolidation or merger in which the Company is
         the continuing entity), or of any sale of the properties and assets of
         the Company as, or substantially as, an entirety to any other person or
         entity, each Warrant then outstanding shall thereafter be convertible
         into the kind and amount of stock or other securities or property
         receivable upon each such reorganization, reclassification, change,
         consolidation, merger or sale by a holder of the number of shares of
         Common Stock for which such Warrant would have been exercisable prior
         to such transaction assuming such Warrant had been exercisable. The
         provisions of this Paragraph (m) shall similarly apply to successive
         reorganizations, reclassifications, changes, consolidations, mergers or
         sales immediately prior to such reorganization, reclassification,
         change, consolidation, merger or sale.

                  (n) Irrespective of any adjustments in the Exercise Price or
         the number or kind of shares purchasable upon exercise of this Warrant,
         Warrants theretofore or thereafter issued may continue to express the
         same price and number and kind of shares as are stated in the similar
         Warrants initially issuable pursuant to this Agreement.

         SECTION 9. WARRANT CALL.

                  (a) If at any time the current market value of a share of
         Common Stock (determined in accordance with Section 11 hereof) equals
         or exceeds three times the Exercise Price then in effect for a period
         of 20 consecutive trading days then, at any time during the five
         trading day period following the last day of such 20 day period the
         Company may, at its option, accelerate the expiration of the Warrants
         to a date not less than 30 days from the date written notice thereof
         (the "Call Notice") is sent to the Registered Holders of the Warrants
         provided (i) a registration statement covering the Warrant Shares filed
         under the Act has been declared effective and remains effective on the
         date fixed for expiration of the Warrants (the "Call Date"), (ii) the
         Warrants and Warrant Shares are not subject to a lock-up agreement and
         (iii) on each day during such 20 consecutive day trading period the
         Common Stock was traded on a national securities exchange, included for
         quotation on the Nasdaq SmallCap Market or National Market System or
         reported by the NASD Over the Counter Bulletin Board.

                  (b) If the conditions set forth in Section 9(a) are met, and
         the Company desires to exercise its right to accelerate the exercise
         date of the Warrants, it shall mail a Call Notice to each of the
         Registered Holders of the Warrants, first class, postage prepaid, at
         their last address as shall appear on the records maintained pursuant
         to Section 6(b). Any notice mailed in the manner provided herein shall
         be conclusively presumed to have been duly given whether or not the
         Registered Holder receives such notice.

                  (c) The Call Notice shall specify (i) the Call Date, which
         shall be no later than the 60th day following the last day of the 20
         consecutive day trading period referred to in Section 9(a), and (ii)
         that the right to exercise the Warrant shall terminate at 5:00 P.M.
         (New York time) on the Call Date. No failure to mail such notice nor
         any defect therein or in the mailing thereof shall affect the validity
         of the proceedings for such acceleration of the Expiration Date except
         as to a Registered Holder (a) to whom notice was not mailed or (b)
         whose notice was defective. An affidavit of the Secretary or an
         Assistant Secretary of the Company that the Call Notice has been mailed
         shall, in the absence of fraud, be prima facie evidence of the facts
         stated therein.

                  (d) Any right to exercise a Warrant shall terminate at 5:00
         P.M. (New York time) on the Call Date. After 5:00 p.m. (New York time)
         on the Call Date, Registered Holders of the Warrants shall have no
         further rights and such Warrants shall expire and become void and all
         rights hereunder and under the Warrant Certificates shall cease.

         SECTION 10. REGISTRATION UNDER THE SECURITIES ACT OF 1933. The Company
agrees to register the Warrant Shares for resale under the Securities Act of

                                      -8-
<PAGE>

1933, as amended (the "Act") on the terms and subject to the conditions set
forth in Annex A to the Subscription Agreement(s) between the Company and each
of the investors in the Private Placement.

         SECTION 11. FRACTIONAL WARRANTS AND FRACTIONAL SHARES. If the number of
shares of Common Stock purchasable upon the exercise of each Warrant is adjusted
pursuant to Section 8 hereof, the Company shall nevertheless not be required to
issue fractions of shares, upon exercise of the Warrants or otherwise, or to
distribute certificates that evidence fractional shares. With respect to any
fraction of a share called for upon any exercise of any Warrant, the Company
shall pay to the holder thereof an amount in cash equal to such fraction
multiplied by the current market price of a share of Common Stock, determined as
follows:

                  (a) If the Common Stock is listed on a national securities
         exchange or admitted to unlisted trading privileges on such exchange or
         listed for trading on the Nasdaq National Market System ("NMS"), the
         current market price shall be the higher of (x) the average of the last
         reported sale prices of the Common Stock on such exchange for the 20
         trading days prior to the date of exercise of this Warrant and (y) the
         last reported sales price on the trading day immediately preceding such
         date; provided that if no such sale is made on a day within such period
         or no closing sale price is quoted, that day's price shall be the
         average of the closing bid and asked prices for such day on such
         exchange or system; or

                  (b) If the Common Stock is not so listed or admitted to
         unlisted trading privileges, but is traded on the Nasdaq SmallCap
         Market, the current market price shall be the higher of (x) the average
         of the closing bid and asked prices for the 20 trading days prior to
         the date of exercise of this Warrant on such market and (y) the last
         reported bid price on the trading day immediately preceding such date
         on such market and if the Common Stock is not so traded, the current
         market price shall be the higher of (i) the mean of the last reported
         bid and asked prices reported by the NASD Over the Counter Bulletin
         Board for the 20 trading days prior to the date of the exercise of this
         Warrant and (ii) the last reported bid price on the trading day
         immediately preceding such date as reported by the NASD Over the
         Counter Bulletin Board; or

                  (c) If the Common Stock is not so listed or admitted to
         unlisted trading privileges and bid and asked prices are not so
         reported, the current market price shall be an amount determined in a
         reasonable manner by the Board of Directors of the Company.

         SECTION 12. WARRANT HOLDERS NOT DEEMED STOCKHOLDERS. No holder of
Warrants shall, as such, be entitled to vote or to receive dividends or be
deemed the holder of Common Stock that may at any time be issuable upon exercise
of such Warrants for any purpose whatsoever, nor shall anything contained herein
be construed to confer upon the holder of Warrants, 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, issue or reclassification of stock, change of par value or
change of stock to no par value, consolidation, merger or conveyance or
otherwise), or to receive notice of meetings, or to receive dividends or
subscription rights, until such Holder shall have exercised such Warrants and
been issued shares of Common Stock in accordance with the provisions hereof.

         SECTION 13. RIGHTS OF ACTION. All rights of action with respect to this
Agreement are vested in the respective Registered Holders of the Warrants, and
any Registered Holder of a Warrant, without consent of the Company or of the
holder of any other Warrant, may, on his own behalf and for his own benefit,
enforce against the Company his right to exercise his Warrants for the purchase
of shares of Common Stock in the manner provided in the Warrant Certificate and
this Agreement.

         SECTION 14. CANCELLATION OF WARRANT CERTIFICATES. If the Company shall
purchase or acquire any Warrant or Warrants, the Warrant Certificate or Warrant
Certificates evidencing the same shall thereupon be canceled by it and retired.

         SECTION 15. MODIFICATION OF AGREEMENT. The parties hereto may by
supplemental agreement make any changes or corrections in this Agreement (i)
that it shall deem appropriate to cure any ambiguity or to correct any defective
or inconsistent provision or manifest mistake or error herein contained; (ii) to
reflect an increase in the number of Warrants which are to be governed by this
Agreement resulting from an increase in the size of the Private Placement or the

                                      -9-
<PAGE>

number of Warrants issued in connection with the Private Placement; (iii) to
provide for a warrant agent for the Warrants; or (iv) that it may deem necessary
or desirable and which shall not adversely affect the interests of the holders
of Warrant Certificates. Except as set forth above, this Agreement shall not be
modified, supplemented or altered in any respect except with the consent in
writing of the Company and the holders of not less than 50% of the outstanding
Warrants.

         SECTION 16. NOTICES. All notices, requests, consents and other
communications hereunder shall be in writing and shall be deemed to have been
made when delivered or mailed first class registered or certified mail, postage
prepaid as follows: if to the Registered Holder of a Warrant Certificate, at the
address of such holder as shown on the registry books maintained by the Company
in its capacity as warrant agent; if to the Company, OmniComm Systems, Inc.,
3250 Mary Street, Suite 402, Miami, Florida 33133, Att: Chief Financial Officer;
and if to Commonwealth, at Commonwealth Associates, 830 Third Avenue, New York,
New York 10022, Att: Carl Kleidman.

         SECTION 17. GOVERNING LAW. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York, without
reference to principles of conflict of laws.

         SECTION 18. BINDING EFFECT. This Agreement shall be binding upon and
inure to the benefit of the Company and Commonwealth (and their respective
successors and assigns) and the holders from time to time of Warrant
Certificates. Nothing in this Agreement is intended or shall be construed to
confer upon any other person any right, remedy or claim, in equity or at law, or
to impose upon any other person any duty, liability or obligation.

         SECTION 19. TERMINATION. This Agreement shall terminate on the earlier
to occur of (i) the close of business on the Expiration Date of all the
Warrants; or (ii) the date upon which all Warrants have been exercised or
called.

         SECTION 20. COUNTERPARTS. This Agreement may be executed in several
counterparts, which taken together shall constitute a single document.

                                 OF COMMON STOCK

                             OMNICOMM SYSTEMS, INC.

                  This certifies that FOR VALUE RECEIVED ___________________ or

Company, as warrant agent, or its successor (the "Warrant Agent"), accompanied
by payment of an amount equal to $.25 for each Warrant (the "Exercise Price") in

certified check or by check drawn on an account of Commonwealth or such other
investment banks and brokerage houses as the Company shall approve, in each case
made payable to OmniComm Systems, Inc. or a Notice of Exchange (as defined in
the Warrant Agreement). The Company may, at its election, reduce the Exercise

conditions set forth in the Warrant Agreement (the "Warrant Agreement"), dated

subject to purchase upon the exercise of each Warrant represented hereby are
subject to modification or adjustment.

                  The Warrants may be called by the Company under certain
circumstances described in the Warrant Agreement.

                  Each Warrant represented hereby is exercisable at the option
of the Registered Holder, but no fractional shares of Common Stock will be
issued. In the case of the exercise of less than all the Warrants represented
hereby, the Company shall cancel this Warrant Certificate upon the surrender
hereof and shall execute and deliver a new Warrant Certificate or Warrant
Certificates of like tenor for the balance of such Warrants.

                  The term "Expiration Date" shall mean 5:00 P.M. (New York
time) on ___ _, 2006 or unless the Warrants are called by the Company prior to
such date. If such date shall in the State of New York be a holiday or a day on

5:00 P.M. (New York time) the next following day which in the State of New York
is not a holiday or a day on which banks are authorized to close. The Company
may, at its election, extend the Expiration Date.

                  This Warrant Certificate is exchangeable, upon the surrender
hereof by the Registered Holder at the corporate office of the Company, for a
new Warrant Certificate or Warrant Certificates of like tenor representing an
equal aggregate number of Warrants, each of such new Warrant Certificates to
represent such number of Warrants as shall be designated by such Registered
Holder at the time of such surrender. Upon due presentment with any tax or other
governmental charge imposed in connection therewith, for registration of
transfer of this Warrant Certificate at such office, a new Warrant Certificate
or Warrant Certificates representing an equal aggregate number of Warrants will
be issued to the transferee in exchange therefor, subject to the limitations
provided in the Warrant Agreement.

                  Prior to the exercise of any Warrant represented hereby, the
Registered Holder shall not be entitled to any of the rights of a stockholder of
the Company, including, without limitation, the right to vote or to receive
dividends or other distributions, and shall not be entitled to receive any
notice of any proceedings of the Company, except as provided in the Warrant
Agreement.

                  Prior to due presentment for registration of transfer hereof,
the Company may deem and treat the Registered Holder as the absolute owner
hereof and of each Warrant represented hereby (notwithstanding any notations of
ownership or writing hereon made by anyone other than a duly authorized officer
of the Company) for all purposes and the Company shall not be affected by any
notice to the contrary.

                  This Warrant Certificate shall be governed by and construed in
accordance with the laws of the State of New York.

         SECTION 3. FORM AND EXECUTION OF WARRANT CERTIFICATES.

                  (a) The Warrant Certificates for the Warrants, shall be
         substantially in the form annexed hereto as Exhibit A (the provisions
         of which are hereby incorporated herein) and may have such letters,
         numbers or other marks of identification or designation and such
         legends, summaries or endorsements printed, lithographed, engraved or
         typed thereon as the Company may deem appropriate and as are not
         inconsistent with the provisions of this Agreement, or as may be
         required to comply with any law or with any rule or regulation made
         pursuant thereto or with any rule or regulation of any stock exchange
         on which the Warrants may be listed, or to conform to usage. The
         Warrant Certificates shall be dated the date of issuance thereof
         (whether upon initial issuance, transfer, exchange or in lieu of
         mutilated, lost, stolen, or destroyed Warrant Certificates) and issued
         in registered form. The Warrants shall be numbered serially with the
         letters PW.

         President or any Vice President and by its Chief Financial Officer,
         Secretary or an Assistant Secretary and shall have imprinted thereon a
         facsimile of the Company's seal. In case any officer of the Company who
         shall have signed any of the Warrant Certificates shall cease to be
         such officer of the Company before the date of issuance of the Warrant
         Certificates and delivery thereof, such Warrant Certificates may
         nevertheless be issued and delivered with the same force and effect as
         though the person who signed such Warrant Certificates had not ceased
         to be such officer of the Company. After execution by the Company,
         Warrant Certificates shall be delivered by the Company to the
         Registered Holder.

                                      -2-

         SECTION 4. EXERCISE.

                  (a) Each Warrant may be exercised by the Registered Holder
         thereof at any time on or after the Initial Warrant Exercise Date, but
         not after the Warrant Expiration Date, upon the terms and subject to
         the conditions set forth herein and in the applicable Warrant
         Certificate. A Warrant shall be deemed to have been exercised
         immediately prior to the close of business on the Exercise Date and the
         person entitled to receive the securities deliverable upon such
         exercise shall be treated for all purposes as the holder upon exercise
         thereof as of the close of business on the Exercise Date. As soon as
         practicable on or after the Exercise Date the Company shall cause to be
         issued and delivered by the Transfer Agent, to the person or persons
         entitled to receive the same, a certificate or certificates for the
         securities deliverable upon such exercise, (plus a certificate for any
         remaining unexercised Warrants of the Registered Holder).

                   (b) The Registered Holder may, at its option, at any time on
         or after the Initial Warrant Exercise Date, exchange Warrants on a
         cashless basis, in whole or in part (a "Warrant Exchange"), for the
         number of Warrant Shares determined in accordance with this Section
         (4)(c), by surrendering the Warrant Certificate at the principal office
         of the Company, accompanied by a notice stating such Registered
         Holder's intent to effect such exchange, the number of Warrants to be
         exchanged and the date on which the Registered Holder requests that
         such Warrant Exchange occur (the "Notice of Exchange"). The Warrant
         Exchange shall take place on the date specified in the Notice of
         Exchange or, if later, the date the Notice of Exchange is received by
         the Company (the "Exchange Date"). Certificates for the shares issuable
         upon such Warrant Exchange and, if applicable, a new Warrant
         Certificate of like tenor evidencing the balance of the Warrants
         remaining subject to the surrendered Warrant Certificate, shall be
         issued as of the Exchange Date and delivered to the Registered Holder
         within seven (7) days following the Exchange Date. In connection with
         any Warrant Exchange, a Warrant Certificate shall represent the right
         to subscribe for and acquire the number of Warrant Shares (rounded to
         the next highest integer) equal to (i) the number of Warrants specified
         by the Registered Holder in its Notice of Exchange (the "Total Number")
         less (ii) the number of Warrant Shares equal to the quotient obtained
         by dividing (A) the product of the Total Number and the existing
         Exercise Price by (B) the current market price of a share of Common
         Stock. Current market price shall have the meaning set forth Section 11
         hereof, except that for purposes hereof, the date of exercise, as used
         in such Section 11 hereof, shall mean the Exchange Date.

         SECTION 5. RESERVATION OF SHARES; BLUE SKY APPROVALS; PAYMENT OF TAXES.

                  (a) The Company covenants that it will at all times following
         the Initial Warrant Exercise Date reserve and keep available out of its
         authorized Common Stock, solely for the purpose of issue upon exercise
         of Warrants, such number of shares of Common Stock as shall then be
         issuable upon the exercise of all outstanding Warrants. The Company
         covenants that all shares of Common Stock which shall be issuable upon
         exercise of the Warrants and payment of the Exercise Price shall, at
         the time of delivery, be duly and validly issued, fully paid,
         nonassessable and free from all taxes, liens and charges with respect
         to the issue thereof (other than those which the Company shall promptly
         pay or discharge).

                  (b) The Company will use reasonable efforts to obtain
         appropriate approvals or registrations under state "blue sky"
         securities laws with respect to the exercise of the Warrants; provided,
         however, that the Company shall not be obligated to file any general
         consent to service of process or qualify as a foreign corporation in
         any jurisdiction. With respect to any such securities laws, however,
         Warrants may not be exercised by, or shares of Common Stock issued to,
         any Registered Holder in any state in which such exercise would be
         unlawful.

                  (c) The Company shall pay all documentary, stamp or similar
         taxes and other governmental charges that may be imposed with respect
         to the issuance of Warrants, or the issuance, or delivery of any shares
         upon exercise of the Warrants; provided, however, that if the shares of
         Common Stock are to be delivered in a name other than the name of the
         Registered Holder of the Warrant Certificate representing any Warrant
         being exercised, then no such delivery shall be made unless the person
         requesting the same has paid to the Company the amount of transfer
         taxes or charges incident thereto, if any.

         SECTION 6. EXCHANGE AND REGISTRATION OF TRANSFER. Subject to the
restrictions on transfer contained in the Warrant Certificates and the
Subscription Agreement(s) between the Company and each of the investors in the
Private Placement:

                  (a) Warrant Certificates may be exchanged for other Warrant
         Certificates representing an equal aggregate number of Warrants or may
         be transferred in whole or in part. Warrant Certificates to be
         exchanged shall be surrendered to the Company at its Corporate Office,
         and upon satisfaction of the terms and provisions hereof, the Company
         shall execute, issue and deliver in exchange therefor the Warrant
         Certificate or Certificates which the Registered Holder making the
         exchange shall be entitled to receive.

                  (b) The Company shall keep at its office books in which,
         subject to such reasonable regulations as it may prescribe, it shall
         register Warrant Certificates and the transfer thereof in accordance
         with its regular practice. Upon due presentment for registration of
         transfer of any Warrant Certificate at its office, the Company shall
         execute, issue and deliver to the transferee or transferees a new
         Warrant Certificate or Certificates representing an equal aggregate
         number of Warrants of the same tranche. The Company shall also make
         available to Noesis for inspection by its agents or employees, from
         time to time as Noesis may request, such original books of accounts and
         record (including original Warrant Certificates surrendered to the
         Company upon exercise of Warrants) as may be maintained by the Company
         in connection with the issuance and exercise of Warrants hereunder,
         such inspections to occur at the Company's Corporate Office during
         normal business hours.

                  (c) With respect to all Warrant Certificates presented for
         registration of transfer, or for exchange or exercise, the subscription
         form on the reverse thereof shall be duly endorsed, or be accompanied
         by a written instrument or instruments of transfer and subscription, in
         form satisfactory to the Company, duly executed by the Registered
         Holder or his attorney-in-fact duly authorized in writing.

                  (d) The Company may require payment by such holder of a sum
         sufficient to cover any tax or other governmental charge that may be
         imposed in connection therewith.

                  (e) All Warrant Certificates surrendered for exercise or for
         exchange shall be promptly canceled by the Company and thereafter
         retained by the Company until termination of this Agreement, or, with
         the prior written consent of Noesis, disposed of or destroyed.

                  (f) Prior to due presentment for registration of transfer
         thereof, the Company may deem and treat the Registered Holder of any
         Warrant Certificate as the absolute, true and lawful owner thereof and
         of each Warrant represented thereby (notwithstanding any notations of
         ownership or writing thereon made by anyone other than a duly
         authorized officer of the Company) for all purposes and the Company
         shall not be affected by any notice to the contrary, except as
         otherwise expressly provided in Section 7 hereof.

         SECTION 7. LOSS OR MUTILATION. Upon receipt by the Company of evidence
satisfactory to it of the ownership of and loss, theft, destruction or
mutilation of any Warrant Certificate and (in case of loss, theft or
destruction) of indemnity satisfactory to them, and (in the case of mutilation)
upon surrender and cancellation thereof, and in the absence of notice to the
Company that the Warrant Certificate has been acquired by a bonafide purchaser,
the Company shall execute and deliver to the Registered Holder in lieu thereof a
new Warrant Certificate of like tenor representing an equal aggregate number of
Warrants. Applicants for a substitute Warrant Certificate shall comply with such
other reasonable regulations and pay such other reasonable charges as the
Company may prescribe.

         SECTION 8. ANTI-DILUTION PROVISIONS. The Exercise Price in effect at
any time and the number and kind of securities purchasable upon the exercise of
the Warrants shall be subject to adjustment from time to time upon the happening
of certain events as follows:

                  (a) In case the Company shall hereafter (i) declare a dividend
         or make a distribution on its outstanding shares of Common Stock in
         shares of Common Stock, (ii) subdivide or reclassify its outstanding
         shares of Common Stock into a greater number of shares, or (iii)
         combine or reclassify its outstanding shares of Common Stock into a
         smaller number of shares, the Exercise Price in effect at the time of

                                      -4-
<PAGE>

         the record date for such dividend or distribution or of the effective
         date of such subdivision, combination or reclassification shall be
         adjusted so that it shall equal the price determined by multiplying the
         Exercise Price by a fraction, the denominator of which shall be the
         number of shares of Common Stock outstanding after giving effect to
         such action, and the numerator of which shall be the number of shares
         of Common Stock outstanding immediately prior to such action. Such
         adjustment shall be made successively whenever any event listed above
         shall occur.

                  (b) In case the Company shall fix a record date for the
         issuance of rights or warrants to all holders of its Common Stock
         entitling them to subscribe for or purchase shares of Common Stock (or
         securities convertible into Common Stock) at a price (the "Subscription
         Price") (or having a conversion price per share) less than the current
         market price (as defined below) on such record date, the Exercise Price
         shall be adjusted so that the same shall equal the price determined by
         multiplying the Exercise Price in effect immediately prior to the date
         of such issuance by a fraction, the numerator of which shall be the sum
         of the number of shares of Common Stock outstanding on the record date
         mentioned below and the number of additional shares of Common Stock
         which the aggregate offering price of the total number of shares of
         Common Stock so offered (or the aggregate conversion price of the
         convertible securities so offered) would purchase at such current
         market price per share of the Common Stock, and the denominator of
         which shall be the sum of the number of shares of Common Stock
         outstanding on such record date and the number of additional shares of
         Common Stock offered for subscription or purchase (or into which the
         convertible securities so offered are convertible). Such adjustment
         shall be made successively whenever such rights or warrants are issued
         and shall become effective immediately after the record date for the
         determination of shareholders entitled to receive such rights or
         warrants.

                  (c) In case the Company shall hereafter distribute to the
         holders of its Common Stock evidences of its indebtedness or assets
         (excluding cash dividends or distributions and dividends or
         distributions referred to in Subsection (a) above) or subscription
         rights or warrants (excluding those referred to in Subsection (b)
         above), then in each such case the Exercise Price in effect thereafter
         shall be determined by multiplying the Exercise Price in effect
         immediately prior thereto by a fraction, the numerator of which shall
         be the total number of shares of Common Stock outstanding multiplied by
         the current market price per share of Common Stock (as defined below),
         less the fair market value (as determined by the Company's Board of
         Directors) of said assets or evidences of indebtedness so distributed
         or of such rights or warrants, and the denominator of which shall be
         the total number of shares of Common Stock outstanding multiplied by
         such current market price per share of Common Stock. Such adjustment
         shall be made successively whenever such a record date is fixed. Such
         adjustment shall be made whenever any such distribution is made and
         shall become effective immediately after the record date for the
         determination of shareholders entitled to receive such distribution.

                  (d) In case the Company shall hereafter issue shares of its
         Common Stock (excluding shares issued (i) in any of the transactions
         described in Subsection (a) above, (ii) upon exercise of options
         granted to the Company's officers, directors, employees and consultants
         under a plan or plans adopted by the Company's Board of Directors or a
         committee thereof and approved by its shareholders, if such shares
         would otherwise be included in this Subsection (d), (but only to the
         extent that the aggregate number of shares excluded by this Subsection
         (d)(ii) does not exceed 15% of the Company's Common Stock outstanding,
         on a fully diluted basis, at the time of any issuance), (iii) upon
         exercise of options, warrants, convertible securities and convertible
         debentures outstanding as of the final closing of the Private
         Placement, (iv) to shareholders of any corporation which merges into
         the Company in proportion to their stock holdings of such corporation
         immediately prior to such merger, upon such merger, (v) in a private
         placement where the Offering Price (as defined below) is at least 75%
         of the current market price, (vi) in a bona fide public offering
         pursuant to a firm commitment underwriting, or (vii) in connection with
         an acquisition of a business or technology which has been approved by a
         majority of the Company's outside directors but only if no adjustment
         is required pursuant to any other specific subsection of this Section 8
         (without regard to Subsection (i) below) with respect to the
         transaction giving rise to such rights) for a consideration per share
         (the "Offering Price") less than the current market price on the date
         of such issuance, the Exercise Price shall be adjusted immediately
         thereafter so that it shall equal the price determined by multiplying
         the Exercise Price in effect immediately prior thereto by a fraction,
         the numerator of which shall be the sum of the number of shares of
         Common Stock outstanding immediately prior to the issuance of such
         additional shares and the number of shares of Common Stock which the
         aggregate consideration received for the issuance of such additional
         shares would purchase at such current market price per share of Common
         Stock, and the denominator of which shall be the number of shares of
         Common Stock outstanding immediately after the issuance of such
         additional shares. Such adjustment shall be made successively whenever
         such an issuance is made.

                                      -5-
<PAGE>

                  (e) In case the Company shall hereafter issue any securities
         convertible into or exchangeable for its Common Stock (excluding
         securities issued in transactions described in Subsections (b) and (c)
         above or in the exclusions set forth in (d)(i) through (vii) above) for
         a consideration per share of Common Stock (the "Exchange Price")
         initially deliverable upon conversion or exchange of such securities
         (determined as provided in Subsection (g) below) less than the current
         market price on the date of such issuance, the Exercise Price shall be
         adjusted immediately thereafter so that it shall equal the price
         determined by multiplying the Exercise Price in effect immediately
         prior thereto by a fraction, the numerator of which shall be the sum of
         the number of shares of Common Stock outstanding immediately prior to
         the issuance of such securities and the number of shares of Common
         Stock which the aggregate consideration received for such securities
         would purchase at such current market price per share of Common Stock,
         and the denominator of which shall be the sum of the number of shares
         of Common Stock outstanding immediately prior to such issuance and the
         maximum number of shares of Common Stock of the Company deliverable
         upon conversion of or in exchange for such securities at the initial
         conversion or exchange price or rate. Such adjustment shall be made
         successively whenever such an issuance is made.

                  (f) Whenever the Exercise Price payable upon exercise of each
         Warrant is adjusted pursuant to Subsections (a), (b), (c), (d) and (e)
         above or pursuant to subsection (j) below, the number of Warrant Shares
         purchasable upon exercise of each Warrant shall simultaneously be
         adjusted by multiplying the number of Warrant Shares initially issuable
         upon exercise of such Warrant by the Exercise Price in effect on the
         date hereof and dividing the product so obtained by the Exercise Price,
         as adjusted.

                  (g) For purposes of any computation respecting consideration
         received pursuant to Subsections (d) and (e) above and (j) below, the
         following shall apply:

                           (A) in the case of the issuance of shares of Common
                  Stock for cash, the consideration shall be the amount of such
                  cash, provided that in no case shall any deduction be made for
                  any commissions, discounts or other expenses incurred by the
                  Company for any underwriting of the issue or otherwise in
                  connection therewith;

                           (B) in the case of the issuance of shares of Common
                  Stock for a consideration in whole or in part other than cash,
                  the consideration other than cash shall be deemed to be the
                  fair market value thereof as determined in good faith by the
                  Board of Directors of the Company (irrespective of the
                  accounting treatment thereof), whose determination shall be
                  conclusive; and

                           (C) in the case of the issuance of securities
                  convertible into or exchangeable for shares of Common Stock,
                  the aggregate consideration received therefor shall be deemed
                  to be the consideration received by the Company for the
                  issuance of such securities plus the additional minimum
                  consideration, if any, to be received by the Company upon the
                  conversion or exchange thereof (the consideration in each case
                  to be determined in the same manner as provided in clauses (A)
                  and (B) of this Subsection (g)). Upon the expiration or
                  termination of any such securities convertible into or
                  exchangeable for shares of Common Stock, the Exercise Price
                  shall be automatically readjusted to the Exercise Price that
                  would have been obtained had such convertible or exchangeable
                  securities not been issued.

                  (h) For the purpose of any computation under Subsection (b),
         (c), (d) and (e) above, the current market price per share of Common
         Stock at any date shall be determined in the manner set forth in
         Section 11 hereof.

                  (i) No adjustment in the Exercise Price shall be required
         unless such adjustment would require an increase or decrease of at
         least five cents ($0.05) in such price; provided, however, that any
         adjustments which by reason of this Subsection (i) are not required to
         be made shall be carried forward and taken into account in any
         subsequent adjustment required to be made hereunder. All calculations
         under this Section 8 shall be made to the nearest cent or to the
         nearest one-hundredth of a share, as the case may be. Anything in this
         Section 8 to the contrary notwithstanding, the Company shall be

                                      -6-
<PAGE>

         entitled, but shall not be required, to make such changes in the
         Exercise Price, in addition to those required by this Section 8, as it
         shall determine, in its sole discretion, to be advisable in order that
         any dividend or distribution in shares of Common Stock, or any
         subdivision, reclassification or combination of Common Stock, hereafter
         made by the Company shall not result in any Federal income tax
         liability to the holders of Common Stock or securities convertible into
         Common Stock (including Warrants).

                  (j) Notwithstanding the other provisions of this Section 8,

                                    (A) in the event that the Company shall at
                  any time issue securities in transactions of the type
                  described in Subsections (b), (d) and (e) of this Section 8
                  (other than securities issued in transactions described in
                  Subsection (d)(i) through (vii) above) having an Offering
                  Price, Subscription Price or Exchange Price less than the
                  Exercise Price, then the Exercise Price shall be immediately
                  reset to equal such lower Offering Price, Subscription Price
                  or Exchange Price and

                                    (B) no adjustment under Subsections (b), (d)
                  or (e) shall be required for issuances below the current
                  market price if (i) the Offering Price, Subscription Price or
                  Exchange Price, as applicable, is at least 300% of the
                  Exercise Price then in effect and (ii) a registration
                  statement covering the Warrant Shares is in effect and remains
                  in effect for the 90 days after such issuance or Rule 144(k)
                  under the Securities Act of 1933, as amended (the "Act") is
                  available for resale of all of the Warrant Shares.

                  (k) Whenever the Exercise Price is adjusted, as herein
         provided, the Company shall promptly cause a notice setting forth the
         adjusted Exercise Price and adjusted number of Warrant Shares issuable
         upon exercise of each Warrant, and, if requested, information
         describing the transactions giving rise to such adjustments, to be
         mailed to the holders at their last addresses appearing in the registry
         books maintained by the Company pursuant to Section 6(b), and shall
         cause a certified copy thereof to be mailed to its transfer agent, if
         any. The Company may retain a firm of independent certified public
         accountants selected by the Board of Directors (who may be the regular
         accountants employed by the Company) to make any computation required
         by this Section 8, and a certificate signed by such firm shall be
         conclusive evidence of the correctness of such adjustment absent
         manifest error.

                  (l) In the event that at any time, as a result of an
         adjustment made pursuant to this Section 8, a holder of Warrants
         thereafter shall become entitled to receive any securities, other than
         Common Stock, thereafter the number of such other securities so
         receivable upon exercise of a Warrant shall be subject to adjustment
         from time to time in a manner and on terms as nearly equivalent as
         practicable to the provisions with respect to the Common Stock
         contained in Subsections (a) to (j), inclusive above.

                  (m) In case of any reorganization, reclassification or change
         of the Common Stock (including any such reorganization,
         reclassification or change in connection with a consolidation or merger
         in which the Company is the continuing entity), or any consolidation of
         the Company with, or merger of the Company with or into, any other
         entity (other than a consolidation or merger in which the Company is
         the continuing entity), or of any sale of the properties and assets of
         the Company as, or substantially as, an entirety to any other person or
         entity, each Warrant then outstanding shall thereafter be convertible
         into the kind and amount of stock or other securities or property
         receivable upon each such reorganization, reclassification, change,
         consolidation, merger or sale by a holder of the number of shares of
         Common Stock for which such Warrant would have been exercisable prior
         to such transaction assuming such Warrant had been exercisable. The
         provisions of this Paragraph (m) shall similarly apply to successive
         reorganizations, reclassifications, changes, consolidations, mergers or
         sales immediately prior to such reorganization, reclassification,
         change, consolidation, merger or sale.

                  (n) Irrespective of any adjustments in the Exercise Price or
         the number or kind of shares purchasable upon exercise of this Warrant,
         Warrants theretofore or thereafter issued may continue to express the
         same price and number and kind of shares as are stated in the similar
         Warrants initially issuable pursuant to this Agreement.

         SECTION 9. WARRANT CALL.

                  (a) If at any time the current market value of a share of
         Common Stock (determined in accordance with Section 11 hereof) equals
         or exceeds three times the Exercise Price then in effect for a period
         of 20 consecutive trading days then, at any time during the five
         trading day period following the last day of such 20 day period the
         Company may, at its option, accelerate the expiration of the Warrants
         to a date not less than 30 days from the date written notice thereof
         (the "Call Notice") is sent to the Registered Holders of the Warrants
         provided (i) a registration statement covering the Warrant Shares filed
         under the Act has been declared effective and remains effective on the
         date fixed for expiration of the Warrants (the "Call Date"), (ii) the
         Warrants and Warrant Shares are not subject to a lock-up agreement and
         (iii) on each day during such 20 consecutive day trading period the
         Common Stock was traded on a national securities exchange, included for
         quotation on the Nasdaq SmallCap Market or National Market System or
         reported by the NASD Over the Counter Bulletin Board.

                  (b) If the conditions set forth in Section 9(a) are met, and
         the Company desires to exercise its right to accelerate the exercise
         date of the Warrants, it shall mail a Call Notice to each of the
         Registered Holders of the Warrants, first class, postage prepaid, at
         their last address as shall appear on the records maintained pursuant
         to Section 6(b). Any notice mailed in the manner provided herein shall
         be conclusively presumed to have been duly given whether or not the
         Registered Holder receives such notice.

                  (c) The Call Notice shall specify (i) the Call Date, which
         shall be no later than the 60th day following the last day of the 20
         consecutive day trading period referred to in Section 9(a), and (ii)
         that the right to exercise the Warrant shall terminate at 5:00 P.M.
         (New York time) on the Call Date. No failure to mail such notice nor
         any defect therein or in the mailing thereof shall affect the validity
         of the proceedings for such acceleration of the Expiration Date except
         as to a Registered Holder (a) to whom notice was not mailed or (b)
         whose notice was defective. An affidavit of the Secretary or an
         Assistant Secretary of the Company that the Call Notice has been mailed
         shall, in the absence of fraud, be prima facie evidence of the facts
         stated therein.

                  (d) Any right to exercise a Warrant shall terminate at 5:00
         P.M. (New York time) on the Call Date. After 5:00 p.m. (New York time)
         on the Call Date, Registered Holders of the Warrants shall have no
         further rights and such Warrants shall expire and become void and all
         rights hereunder and under the Warrant Certificates shall cease.

         SECTION 10. REGISTRATION UNDER THE SECURITIES ACT OF 1933. The Company
agrees to register the Warrant Shares for resale under the Securities Act of
1933, as amended (the "Act") on the terms and subject to the conditions set
forth in Annex A to the Subscription Agreement(s) between the Company and each
of the investors in the Private Placement.

         SECTION 11. FRACTIONAL WARRANTS AND FRACTIONAL SHARES. If the number of
shares of Common Stock purchasable upon the exercise of each Warrant is adjusted
pursuant to Section 8 hereof, the Company shall nevertheless not be required to
issue fractions of shares, upon exercise of the Warrants or otherwise, or to
distribute certificates that evidence fractional shares. With respect to any
fraction of a share called for upon any exercise of any Warrant, the Company
shall pay to the holder thereof an amount in cash equal to such fraction
multiplied by the current market price of a share of Common Stock, determined as
follows:

                  (a) If the Common Stock is listed on a national securities
         exchange or admitted to unlisted trading privileges on such exchange or
         listed for trading on the Nasdaq National Market System ("NMS"), the
         current market price shall be the higher of (x) the average of the last
         reported sale prices of the Common Stock on such exchange for the 20
         trading days prior to the date of exercise of this Warrant and (y) the
         last reported sales price on the trading day immediately preceding such
         date; provided that if no such sale is made on a day within such period
         or no closing sale price is quoted, that day's price shall be the
         average of the closing bid and asked prices for such day on such
         exchange or system; or

                  (b) If the Common Stock is not so listed or admitted to
         unlisted trading privileges, but is traded on the Nasdaq SmallCap
         Market, the current market price shall be the higher of (x) the average
         of the closing bid and asked prices for the 20 trading days prior to
         the date of exercise of this Warrant on such market and (y) the last

                                      -8-
<PAGE>

         reported bid price on the trading day immediately preceding such date
         on such market and if the Common Stock is not so traded, the current
         market price shall be the higher of (i) the mean of the last reported
         bid and asked prices reported by the NASD Over the Counter Bulletin
         Board for the 20 trading days prior to the date of the exercise of this
         Warrant and (ii) the last reported bid price on the trading day
         immediately preceding such date as reported by the NASD Over the
         Counter Bulletin Board; or

                  (c) If the Common Stock is not so listed or admitted to
         unlisted trading privileges and bid and asked prices are not so
         reported, the current market price shall be an amount determined in a
         reasonable manner by the Board of Directors of the Company.

         SECTION 12. WARRANT HOLDERS NOT DEEMED STOCKHOLDERS. No holder of
Warrants shall, as such, be entitled to vote or to receive dividends or be
deemed the holder of Common Stock that may at any time be issuable upon exercise
of such Warrants for any purpose whatsoever, nor shall anything contained herein
be construed to confer upon the holder of Warrants, 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, issue or reclassification of stock, change of par value or
change of stock to no par value, consolidation, merger or conveyance or
otherwise), or to receive notice of meetings, or to receive dividends or
subscription rights, until such Holder shall have exercised such Warrants and
been issued shares of Common Stock in accordance with the provisions hereof.

         SECTION 13. RIGHTS OF ACTION. All rights of action with respect to this
Agreement are vested in the respective Registered Holders of the Warrants, and
any Registered Holder of a Warrant, without consent of the Company or of the
holder of any other Warrant, may, on his own behalf and for his own benefit,
enforce against the Company his right to exercise his Warrants for the purchase
of shares of Common Stock in the manner provided in the Warrant Certificate and
this Agreement.

         SECTION 14. CANCELLATION OF WARRANT CERTIFICATES. If the Company shall
purchase or acquire any Warrant or Warrants, the Warrant Certificate or Warrant
Certificates evidencing the same shall thereupon be canceled by it and retired.

         SECTION 15. MODIFICATION OF AGREEMENT. The parties hereto may by
supplemental agreement make any changes or corrections in this Agreement (i)
that it shall deem appropriate to cure any ambiguity or to correct any defective
or inconsistent provision or manifest mistake or error herein contained; (ii) to
reflect an increase in the number of Warrants which are to be governed by this
Agreement resulting from an increase in the size of the Private Placement or the
number of Warrants issued in connection with the Private Placement; (iii) to
provide for a warrant agent for the Warrants; or (iv) that it may deem necessary
or desirable and which shall not adversely affect the interests of the holders
of Warrant Certificates. Except as set forth above, this Agreement shall not be
modified, supplemented or altered in any respect except with the consent in
writing of the Company and the holders of not less than 50% of the outstanding
Warrants.

         SECTION 16. NOTICES. All notices, requests, consents and other
communications hereunder shall be in writing and shall be deemed to have been
made when delivered or mailed first class registered or certified mail, postage
prepaid as follows: if to the Registered Holder of a Warrant Certificate, at the
address of such holder as shown on the registry books maintained by the Company
in its capacity as warrant agent; if to the Company, OmniComm Systems, Inc.,

Officer; and if to Noesis, at Noesis Capital, 1801 Clint Moore Road, Suite 100,
Boca Raton, FL, 33487, Attn: Cory Nass.

         SECTION 17. GOVERNING LAW. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York, without
reference to principles of conflict of laws.

         SECTION 18. BINDING EFFECT. This Agreement shall be binding upon and
inure to the benefit of the Company and Noesis (and their respective successors
and assigns) and the holders from time to time of Warrant Certificates. Nothing
in this Agreement is intended or shall be construed to confer upon any other
person any right, remedy or claim, in equity or at law, or to impose upon any
other person any duty, liability or obligation.

Warrants; or (ii) the date upon which all Warrants have been exercised or
called.

counterparts, which taken together shall constitute a single document.

                          VOID AFTER_____________, 2009

                        WARRANT CERTIFICATE FOR PURCHASE
                                 OF COMMON STOCK

                             OMNICOMM SYSTEMS, INC.

                  This certifies that FOR VALUE RECEIVED ______________or
registered assigns (the "Registered Holder") is the owner of the number of
Warrants ("Warrants") specified above. Each Warrant initially entitles the
Registered Holder to purchase, subject to the terms and conditions set forth in
this Certificate and the Warrant Agreement (as hereinafter defined), one fully
paid and nonassessable share of common stock, par value $.001 per share ("Common
Stock") of OmniComm Systems, Inc., a Delaware corporation (the "Company") at any
time commencing on the Initial Warrant Exercise Date (as defined in the Warrant
Agreement) and prior to the Expiration Date (as hereinafter defined), upon the
presentation and surrender of this Warrant Certificate with the Subscription
Form on the reverse hereof duly executed, at the corporate office of the
Company, as warrant agent, or its successor (the "Warrant Agent"), accompanied
by payment of an amount equal to $0.25 for each Warrant (the "Exercise Price")
in lawful money of the United States of America in cash or by official bank or
certified check or by check drawn on an account of Noesis or such other
investment banks and brokerage houses as the Company shall approve, in each case
made payable to OmniComm Systems, Inc. or a Notice of Exchange (as defined in
the Warrant Agreement). The Company may, at its election, reduce the Exercise
Price.

                  This Warrant Certificate and each Warrant represented hereby
are issued pursuant to and are subject in all respects to the terms and
conditions set forth in the Warrant Agreement (the "Warrant Agreement"), dated
March 29, 2002 by and among the Company and Noesis Capital Corp.

                  In the event of certain contingencies provided for in the
Warrant Agreement, the Exercise Price or the number of shares of Common Stock
subject to purchase upon the exercise of each Warrant represented hereby are
subject to modification or adjustment.

                  The Warrants may be called by the Company under certain
circumstances described in the Warrant Agreement.

                  Each Warrant represented hereby is exercisable at the option
of the Registered Holder, but no fractional shares of Common Stock will be
issued. In the case of the exercise of less than all the Warrants represented
hereby, the Company shall cancel this Warrant Certificate upon the surrender
hereof and shall execute and deliver a new Warrant Certificate or Warrant
Certificates of like tenor for the balance of such Warrants.

                  The term "Expiration Date" shall mean 5:00 P.M. (New York
time) on_March 29, 2009 or unless the Warrants are called by the Company prior
to such date. If such date shall in the State of New York be a holiday or a day
on which the banks are authorized to close, then the Expiration Date shall mean
5:00 P.M. (New York time) the next following day which in the State of New York
is not a holiday or a day on which banks are authorized to close. The Company
may, at its election, extend the Expiration Date.

<PAGE>

                  This Warrant Certificate is exchangeable, upon the surrender
hereof by the Registered Holder at the corporate office of the Company, for a
new Warrant Certificate or Warrant Certificates of like tenor representing an
equal aggregate number of Warrants, each of such new Warrant Certificates to
represent such number of Warrants as shall be designated by such Registered
Holder at the time of such surrender. Upon due presentment with any tax or other
governmental charge imposed in connection therewith, for registration of
transfer of this Warrant Certificate at such office, a new Warrant Certificate
or Warrant Certificates representing an equal aggregate number of Warrants will
be issued to the transferee in exchange therefor, subject to the limitations
provided in the Warrant Agreement.

                  Prior to the exercise of any Warrant represented hereby, the
Registered Holder shall not be entitled to any of the rights of a stockholder of
the Company, including, without limitation, the right to vote or to receive
dividends or other distributions, and shall not be entitled to receive any
notice of any proceedings of the Company, except as provided in the Warrant
Agreement.

                  Prior to due presentment for registration of transfer hereof,
the Company may deem and treat the Registered Holder as the absolute owner
hereof and of each Warrant represented hereby (notwithstanding any notations of
ownership or writing hereon made by anyone other than a duly authorized officer
of the Company) for all purposes and the Company shall not be affected by any
notice to the contrary.

                  This Warrant Certificate shall be governed by and construed in
accordance with the laws of the State of Florida.
