        pari passu to the Corporation’s Series A Convertible Preferred Stock and the
        Corporation’s Series B 9% Convertible Preferred Stock as to payment of dividends
        and liquidation preference.  Capitalized terms not otherwise defined
        herein shall have the meaning given such terms in Section 1 hereof.

      

      Section
        3.  Dividends.

      

      a)           Dividends
        in Cash or in
        Kind.  Holders shall
        be entitled
        to receive, and the Corporation shall pay, cumulative dividends at the rate
        per
        share (as a percentage of the Stated Value per share) of 7% per
        annum,
        payable semi-annually on January 1 and
        July 1, beginning on July 1, 2007 and on each Conversion Date (with respect
        only
        to Preferred Stock being converted) (each such date, a “Dividend Payment
        Date”) (if any
        Dividend Payment Date is not a Trading Day, the applicable payment shall
        be due
        on the next succeeding Trading Day) in cash or duly authorized, validly issued,
        fully paid and non-assessable shares of Common Stock as set forth in this
        Section 3(a), or a combination thereof (the amount to be paid in shares of
        Common Stock, the “Dividend Share
        Amount”).  The form of dividend
        payments to each Holder shall be determined in the following order of priority:
        (i) if funds are legally available for the payment of dividends and the Equity
        Conditions have not been met during the 20 consecutive Trading Days immediately
        prior to the applicable Dividend Payment Date, in cash only; (ii) if funds
        are
        legally available for the payment of dividends and the Equity Conditions
        have
        been met during the 20 consecutive Trading Days immediately prior to the
        applicable Dividend Payment Date, at the sole election of the Corporation,
        in
        cash or shares of Common Stock which shall be valued solely for such purpose
        at
        90% of the average of the VWAPs for the 20 consecutive Trading Days ending
        on
        the Trading Day that is immediately prior to the Dividend Payment Date; (iii)
        if
        funds are not legally available for the payment of dividends and the Equity
        Conditions have been met during the 20 consecutive Trading Days immediately
        prior to the applicable Dividend Payment Date, in shares of Common Stock
        which
        shall be valued solely for such purpose at 90% of the average of the VWAPs
        for
        the 20 consecutive Trading Days ending on the Trading Day that is immediately
        prior to the Dividend Payment Date; (iv) if funds are not legally available
        for
        the payment of dividends and the Equity Condition relating to an effective
        Conversion Shares Registration Statement has been waived by such Holder,
        as to
        such Holder only, in unregistered shares of Common Stock which shall be valued
        solely for such purpose at 90% of the average of the VWAPs for the 20
        consecutive Trading Days ending on the Trading Day that is immediately prior
        to
        the Dividend Payment Date; and (v) if funds are not legally available for
        the
        payment of dividends and the Equity Conditions have not been met during the
        20
        consecutive Trading Days immediately prior to the applicable Dividend Payment
        Date, then, at the election of such Holder, such dividends shall accrue to
        the
        next Dividend Payment Date or shall be accreted to, and increase, the
        outstanding Stated Value.  The Holders shall have the same rights and
        remedies with respect to the delivery of any such shares as if such shares
        were
        being issued pursuant to Section 6.  On the Closing Date the
        Corporation shall have notified the Holders whether or not it may legally
        pay
        cash dividends as of the Closing Date.  The Corporation shall promptly
        notify the Holders at any time the Corporation shall become able or unable,
        as
        the case may be, to legally pay cash dividends.  If at any time the
        Corporation has the right to pay dividends in cash or Common Stock, the
        Corporation must provide the Holders with at least 20 Trading Days’ notice of
        its election to pay a regularly scheduled dividend in Common Stock (the
        Corporation may indicate in such notice that the election contained in such
        notice shall continue for later periods until revised by a subsequent
        notice).  Dividends on the Preferred Stock shall be calculated on the
        basis of a 360-day year, consisting of twelve 30 calendar day periods, shall
        accrue daily commencing on the Original Issue Date, and shall be deemed to
        accrue from such date whether or not earned or declared and whether or not
        there
        are profits, surplus or other funds of the Corporation legally available
        for the
        payment of dividends.  Except as otherwise provided herein, if at any
        time the Corporation pays dividends partially in cash and partially in shares,
        then such payment shall be distributed ratably among the Holders based upon
        the
        number of shares of Preferred Stock held by each Holder on such Dividend
        Payment
        Date.  Any dividends, whether paid in cash or shares of Common Stock,
        that are not paid within three Trading Days following a Dividend Payment
        Date
        shall continue to accrue and shall entail a late fee, which must be paid
        in
        cash, at the rate of 18% per annum or the lesser rate permitted by applicable
        law (such fees to accrue daily, from the Dividend Payment Date through and
        including the date of payment).  If at any time the Corporation
        delivers a notice to the Holders of its election to pay the dividends in
        shares
        of Common Stock, the Corporation shall timely file a prospectus supplement
        pursuant to Rule 424 disclosing such election.

      
         

        
          5

          
            

          

        

        
          
          

        

      

      b)           So
        long as any Preferred Stock shall
        remain outstanding, neither the Corporation nor any Subsidiary thereof shall
        redeem, purchase or otherwise acquire directly or indirectly any Junior
        Securities.  So long as any Preferred Stock shall remain outstanding,
        neither the Corporation nor any Subsidiary thereof shall directly or indirectly
        pay or declare any dividend or make any distribution (other than a dividend
        or
        distribution described in Section 6 or dividends due and paid in the ordinary
        course on preferred stock of the Corporation at such times when the Corporation
        is in compliance with its payment and other obligations hereunder) upon,
        nor
        shall any distribution be made in respect of, any Junior Securities so long
        as
        any dividends due on the Preferred Stock remain unpaid, nor shall any monies
        be
        set aside for or applied to the purchase or redemption (through a sinking
        fund
        or otherwise) of any Junior Securities.

       

      Section
        4.  Voting Rights.  Except as otherwise provided
        herein and as otherwise required by law, the Preferred Stock shall have no
        voting rights.  However, so long as any shares of Preferred Stock are
        outstanding, the Corporation shall not, without the affirmative vote of the
        Holders of at least 81% of the shares of the Preferred Stock then outstanding,
        (a) alter or change adversely the powers, preferences or rights given to
        the
        Preferred Stock or alter or amend this Certificate of Designation, (b) authorize
        or create any class of stock ranking as to dividends, redemption or distribution
        of assets upon a Liquidation (as defined in Section 5) senior to or otherwise
        pari passu with the Preferred Stock, (c) amend its articles of incorporation
        or
        other charter documents so as to affect adversely any rights of the Holders,
        (d)
        increase the authorized number of shares of Preferred Stock, or (e) enter
        into
        any agreement with respect to the foregoing.

      

      Section
        5.  Liquidation.  Upon any liquidation,
        dissolution or winding-up of the Corporation, whether voluntary or involuntary
        (a “Liquidation”), the Holders shall be entitled to receive out of the
        assets of the Corporation, whether such assets are capital or surplus, for
        each
        share of Preferred Stock an amount equal to the Stated Value per share plus
        any
        accrued and unpaid dividends thereon and any other fees or liquidated damages
        owing thereon before any distribution or payment shall be made to the holders
        of
        any Junior Securities, and if the assets of the Corporation shall be
        insufficient to pay in full such amounts, then the entire assets to be
        distributed to the Holders shall be distributed among the Holders ratably
        in
        accordance with the respective amounts that would be payable on such shares
        if
        all amounts payable thereon were paid in full, paripassu with the
        Corporation’s Series A Convertible Preferred Stock and the Series B 9%
        Convertible Preferred Stock treated together as a class based upon the
        liquidation preferences of each such series.  A Fundamental
        Transaction or Change of Control Transaction shall not be treated as a
        Liquidation.  The Corporation shall mail written notice of any such
        Liquidation, not less than 45 days prior to the payment date stated therein,
        to
        each record Holder.

      

      Section
        6.  Conversion.

      

      a)           Conversions
        at Option of
        Holder.  Each share of
        Preferred
        Stock shall be convertible into that number of shares of Common Stock (subject
        to the limitations set forth in Sections 6(c)) determined by dividing the
        Stated
        Value of such share of Preferred Stock by the Conversion Price, at the option
        of
        the Holder, at any time and from time to time from and after the Original
        Issue
        Date.  Holders shall effect conversions by providing the Corporation
        with the form of conversion notice attached hereto as Annex A
        (a “Notice of Conversion”).  Each
        Notice of
        Conversion shall specify the number of shares of Preferred Stock to be
        converted, the number of shares of Preferred Stock owned prior to the conversion
        at issue, the number of shares of Preferred Stock owned subsequent to the
        conversion at issue and the date on which such conversion is to be effected,
        which date may not be prior to the date the Holder delivers such Notice of
        Conversion to the Corporation by facsimile (the “Conversion Date”).  If
        no Conversion Date is
        specified in a Notice of Conversion, the Conversion Date shall be the date
        that
        such Notice of Conversion to the Corporation is deemed delivered
        hereunder.  The calculations and entries set forth in the Notice of
        Conversion shall control in the absence of manifest or mathematical
        error.  To effect conversions, as the case may be, of shares of
        Preferred Stock, a Holder shall not be required to surrender the certificate(s)
        representing such shares of Preferred Stock to the Corporation unless all
        of the
        shares of Preferred Stock represented thereby are so converted, in which
        case
        such Holder shall deliver the certificate representing such shares of Preferred
        Stock promptly following the Conversion Date at issue.  Shares of
        Preferred Stock converted into Common Stock or redeemed in accordance with
        the
        terms hereof shall be canceled and may not be reissued.

      

      b)           Conversion
        Price.  The conversion price for the Preferred Stock shall equal
        $0.48 per share for the holders of the Preferred Stock on the Plan Closing
        Date
        (the “Conversion Price”).

      

      
        
          
          

        

        
          6

          
            

          

        

        
          
          

        

      

      c)           Beneficial
        Ownership Limitation.  The Corporation shall not effect any
        conversion of the Preferred Stock, and a Holder shall not have the right
        to
        convert any portion of the Preferred Stock, to the extent that, after giving
        effect to the conversion set forth on the applicable Notice of Conversion,
        such
        Holder (together with such Holder’s Affiliates, and any other Person or entity
        acting as a group together with such Holder or any of such Holder’s Affiliates)
        would beneficially own in excess of the Beneficial Ownership Limitation (as
        defined below).  For purposes of the foregoing sentence, the number of
        shares of Common Stock beneficially owned by such Holder and its Affiliates
        shall include the number of shares of Common Stock issuable upon conversion
        of
        the Preferred Stock with respect to which such determination is being made,
        but
        shall exclude the number of shares of Common Stock which are issuable upon
        (A)
        conversion of the remaining, unconverted Stated Value of Preferred Stock
        beneficially owned by such Holder or any of its Affiliates and (B) exercise
        or
        conversion of the unexercised or unconverted portion of any other securities
        of
        the Corporation subject to a limitation on conversion or exercise analogous
        to
        the limitation contained herein (including the Warrants) beneficially owned
        by
        such Holder or any of its Affiliates.  Except as set forth in the
        preceding sentence, for purposes of this Section 6(c), beneficial ownership
        shall be calculated in accordance with Section 13(d) of the Exchange Act
        and the
        rules and regulations promulgated thereunder. To the extent that the limitation
        contained in this Section 6(c) applies, the determination of whether the
        Preferred Stock is convertible (in relation to other securities owned by
        such
        Holder together with any Affiliates) and of how many shares of Preferred
        Stock
        are convertible shall be in the sole discretion of such Holder, and the
        submission of a Notice of Conversion shall be deemed to be such Holder’s
        determination of whether the shares of Preferred Stock may be converted (in
        relation to other securities owned by such Holder together with any Affiliates)
        and how many shares of the Preferred Stock are convertible, in each case
        subject
        to such aggregate percentage limitations. To ensure compliance with this
        restriction, each Holder will be deemed to represent to the Corporation each
        time it delivers a Notice of Conversion that such Notice of Conversion has
        not
        violated the restrictions set forth in this paragraph and the Corporation
        shall
        have no obligation to verify or confirm the accuracy of such determination.
        In
        addition, a determination as to any group status as contemplated above shall
        be
        determined in accordance with Section 13(d) of the Exchange Act and the rules
        and regulations promulgated thereunder. For purposes of this Section 6(c),
        in
        determining the number of outstanding shares of Common Stock, a Holder may
        rely
        on the number of outstanding shares of Common Stock as stated in the most
        recent
        of the following: (A) the Corporation’s most recent Form 10-QSB or Form 10-KSB,
        as the case may be, (B) a more recent public announcement by the Corporation
        or
        (C) a more recent notice by the Corporation or the Corporation’s transfer agent
        setting forth the number of shares of Common Stock outstanding.  Upon
        the written or oral request of a Holder, the Corporation shall within two
        Trading Days confirm orally and in writing to such Holder the number of shares
        of Common Stock then outstanding.  In any case, the number of
        outstanding shares of Common Stock shall be determined after giving effect
        to
        the conversion or exercise of securities of the Corporation, including the
        Preferred Stock, by such Holder or its Affiliates since the date as of which
        such number of outstanding shares of Common Stock was reported. The “Beneficial
        Ownership Limitation” shall be 4.99% of the number of shares of the Common Stock
        outstanding immediately after giving effect to the issuance of shares of
        Common
        Stock issuable upon conversion of Preferred Stock held by the applicable
        Holder.
        The Beneficial Ownership Limitation provisions of this Section 6(c) may be
        waived by such Holder, at the election of such Holder, upon not less than
        61
        days’ prior notice to the Corporation, to change the Beneficial Ownership
        Limitation to 9.99% of the number of shares of the Common Stock outstanding
        immediately after giving effect to the issuance of shares of Common Stock
        upon
        conversion of Preferred Stock held by the applicable Holder and the provisions
        of this Section 6(c) shall continue to apply. Upon such a change by a Holder
        of
        the Beneficial Ownership Limitation from such 4.99% limitation to such 9.99%
        limitation, the Beneficial Ownership Limitation shall not be further waived
        by
        such Holder. The provisions of this paragraph shall be construed and implemented
        in a manner otherwise than in strict conformity with the terms of this Section
        6(c) to correct this paragraph (or any portion hereof) which may be defective
        or
        inconsistent with the intended Beneficial Ownership Limitation herein contained
        or to make changes or supplements necessary or desirable to properly give
        effect
        to such limitation. The limitations contained in this paragraph shall apply
        to a
        successor holder of Preferred Stock.  Notwithstanding anything set
        forth in this Section 6(c), the 4.99% and 9.99% beneficial ownership limitations
        imposed by this Section 6(c) shall not apply to Common Stock issuable upon
        conversion of the Preferred Stock in connection with the Plan.

       

      d)           Mechanics
        of
        Conversion.

      

      i.           Delivery
        of Certificate Upon
        Conversion.  Not later than
        three
        Trading Days after each Conversion Date (the “Share Delivery
        Date”), the Corporation
        shall deliver to
        the Holder (A) a certificate or certificates which, after the Effective Date,
        shall be free of restrictive legends and trading restrictions (other than
        those
        required by the Purchase Agreement) representing the number of shares of
        Common
        Stock being acquired upon the conversion of shares of Preferred Stock, and
        (B) a
        bank check in the amount of accrued and unpaid dividends (if the Corporation
        has
        elected or is required to pay accrued dividends in cash).  After the
        Effective Date, the Corporation shall, upon request of the Holder, deliver
        any
        certificate or certificates required to be delivered by the Corporation under
        this Section electronically through the Depository Trust Company or another
        established clearing corporation performing similar functions if the
        Corporation’s transfer agent is a participant in such system.  If in
        the case of any Notice of Conversion such certificate or certificates are
        not
        delivered to or as directed by the applicable Holder by the third Trading
        Day
        after the Conversion Date, the Holder shall be entitled to elect by written
        notice to the Corporation at any time on or before its receipt of such
        certificate or certificates thereafter, to rescind such conversion, in which
        event the Corporation shall immediately return the certificates representing
        the
        shares of Preferred Stock tendered for conversion.

      

      
        
          
          

        

        
          7

          
            

          

        

         

      

      ii.           Obligation
        Absolute; Partial
        Liquidated Damages.  The Corporation’s
        obligation to issue and deliver the Conversion Shares upon conversion of
        Preferred Stock in accordance with the terms hereof are absolute and
        unconditional, irrespective of any action or inaction by a Holder to enforce
        the
        same, any waiver or consent with respect to any provision hereof, the recovery
        of any judgment against any Person or any action to enforce the same, or
        any
        setoff, counterclaim, recoupment, limitation or termination, or any breach
        or
        alleged breach by such Holder or any other Person of any obligation to the
        Corporation or any violation or alleged violation of law by such Holder or
        any
        other Person, and irrespective of any other circumstance which might otherwise
        limit such obligation of the Corporation to such Holder in connection with
        the
        issuance of such Conversion Shares; provided,
however,
        that such delivery shall not operate
        as a waiver by the Corporation of any such action that the Corporation may
        have
        against such Holder.  In the event a Holder shall elect to convert any
        or all of the Stated Value of its Preferred Stock, the Corporation may not
        refuse conversion based on any claim that such Holder or any one associated
        or
        affiliated with such Holder has been engaged in any violation of law, agreement
        or for any other reason, unless an injunction from a court, on notice to
        Holder,
        restraining and/or enjoining conversion of all or part of the Preferred Stock
        of
        such Holder shall have been sought and obtained, and the Corporation posts
        a
        surety bond for the benefit of such Holder in the amount of 150% of the Stated
        Value of Preferred Stock which is subject to the injunction, which bond shall
        remain in effect until the completion of arbitration/litigation of the
        underlying dispute and the proceeds of which shall be payable to such Holder
        to
        the extent it obtains judgment.  In the absence of such injunction,
        the Corporation shall issue Conversion Shares and, if applicable, cash, upon
        a
        properly noticed conversion.  If the Corporation fails to deliver to a
        Holder such certificate or certificates pursuant to Section 6(e)(i) on the
        second Trading Day after the Share Delivery Date applicable to such conversion,
        the Corporation shall pay to such Holder, in cash, as liquidated damages
        and not
        as a penalty, for each $5,000 of Stated Value of Preferred Stock being
        converted, $50 per Trading Day (increasing to $100 per Trading Day after
        the
        third Trading Day and increasing to $200 per Trading Day after the sixth
        Trading
        Day after such damages begin to accrue) for each Trading Day after such second
        Trading Day after the Share Delivery Date until such certificates are
        delivered.  Nothing herein shall limit a Holder’s right to pursue
        actual damages or declare a Triggering Event pursuant to Section 9 for the
        Corporation’s failure to deliver Conversion Shares within the period specified
        herein and such Holder shall have the right to pursue all remedies available
        to
        it hereunder, at law or in equity including, without limitation, a decree
        of
        specific performance and/or injunctive relief.  The Exercise of any
        such rights shall not prohibit a Holder from seeking to enforce damages pursuant
        to any other Section hereof or under applicable law.

       

      iii.           Compensation
        for Buy-In on Failure
        to Timely Deliver Certificates Upon Conversion.  If the Corporation
        fails
        to deliver to a Holder the applicable certificate or certificates by the
        Share
        Delivery Date pursuant to Section 6(e)(i), and if after such Share Delivery
        Date
        such Holder is required by its brokerage firm to purchase (in an open market
        transaction or otherwise), or the Holder’s brokerage firm purchases, shares of
        Common Stock to deliver in satisfaction of a sale by such Holder of the
        Conversion Shares which such Holder was entitled to receive upon the conversion
        relating to such Share Delivery Date (a “Buy-In”),
        then the Corporation shall (A) pay
        in cash to such Holder (in addition to any other remedies available to or
        elected by such Holder) the amount by which (x) such Holder’s total purchase
        price (including any brokerage commissions) for the shares of Common Stock
        so
        purchased exceeds (y) the product of (1) the aggregate number of shares of
        Common Stock that such Holder was entitled to receive from the conversion
        at
        issue multiplied by (2) the actual sale price at which the sell order giving
        rise to such purchase obligation was executed (including any brokerage
        commissions) and (B) at the option of such Holder, either reissue (if
        surrendered) the shares of Preferred Stock equal to the number of shares
        of
        Preferred Stock submitted for conversion or deliver to such Holder the number
        of
        shares of Common Stock that would have been issued if the Corporation had timely
        complied with its delivery requirements under Section 6(e)(i).  For
        example, if a Holder purchases shares of Common Stock having a total purchase
        price of $11,000 to cover a Buy-In with respect to an attempted conversion
        of
        shares of Preferred Stock with respect to which the actual sale price (including
        any brokerage commissions) giving rise to such purchase obligation was a
        total
        of $10,000 under clause (A) of the immediately preceding sentence, the
        Corporation shall be required to pay such Holder $1,000.  The Holder
        shall provide the Corporation written notice indicating the amounts payable
        to
        such Holder in respect of the Buy-In and, upon request of the Corporation,
        evidence of the amount of such loss.  Nothing herein shall limit a
        Holder’s right to pursue any other remedies available to it hereunder, at law or
        in equity including, without limitation, a decree of specific performance
        and/or
        injunctive relief with respect to the Corporation’s failure to timely deliver
        certificates representing shares of Common Stock upon conversion of the shares
        of Preferred Stock as required pursuant to the terms hereof.

      

      iv.           Reservation
        of Shares Issuable Upon
        Conversion.  The Corporation
        covenants
        that it will at all times reserve and keep available out of its authorized
        and
        unissued shares of Common Stock solely for the purpose of issuance upon
        conversion of the Preferred Stock and payment of dividends for three years
        from
        any point in time on the Preferred Stock, each as herein provided, free from
        preemptive rights or any other actual contingent purchase rights of Persons
        other than the Holders, not less than such number of shares of the Common
        Stock
        as shall (subject to any additional requirements of the Corporation as to
        reservation of such shares set forth in the Purchase Agreement) be issuable
        (taking into account the adjustments and restrictions of Section 7) upon
        the
        conversion of all outstanding shares of Preferred Stock.  The
        Corporation covenants that all shares of Common Stock that shall be so issuable
        shall, upon issue, be duly and validly authorized, issued and fully paid,
        nonassessable and, if the Conversion Shares Registration Statement is then
        effective under the Securities Act, registered for public sale in accordance
        with such Conversion Shares Registration Statement.

      

      v.           Fractional
        Shares.  Upon a conversion
        hereunder, the Corporation shall not be required to issue stock certificates
        representing fractions of shares of Common Stock, but may if otherwise
        permitted, make a cash payment in respect of any final fraction of a share
        based
        on the VWAP at such time.  If the Corporation elects not, or is
        unable, to make such a cash payment, the Holders shall be entitled to receive,
        in lieu of the final fraction of a share, one whole share of Common
        Stock.

      

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

      Section
        7.  Certain Adjustments.

      

      a)           Stock
        Dividends and Stock
        Splits.  If
        the Corporation, at any time while this Preferred Stock is outstanding: (A)
        pays
        a stock dividend or otherwise makes a distribution or distributions payable
        in
        shares of Common Stock on shares of Common Stock or any other Common Stock
        Equivalents (which, for avoidance of doubt, shall not include any shares
        of
        Common Stock issued by the Corporation upon conversion of, or payment of
        a
        dividend on, this Preferred Stock, the Series A Convertible Preferred Stock
        or
        the Series B 9% Convertible Preferred Stock); (B) subdivides outstanding
        shares
        of Common Stock into a larger number of shares; (C) combines (including by
        way
        of a reverse stock split) outstanding shares of Common Stock into a smaller
        number of shares; or (D) issues, in the event of a reclassification of shares
        of
        the Common Stock, any shares of capital stock of the Corporation, then the
        Conversion Price shall be multiplied by a fraction of which the numerator
        shall
        be the number of shares of Common Stock (excluding any treasury shares of
        the
        Corporation) outstanding immediately before such event and of which the
        denominator shall be the number of shares of Common Stock outstanding
        immediately after such event.  Any adjustment made pursuant to this
        Section 7(a) shall become effective immediately after the record date for
        the
        determination of stockholders entitled to receive such dividend or distribution
        and shall become effective immediately after the effective date in the case
        of a
        subdivision, combination or re-classification.

      

      b)           Subsequent
        Equity Sales.  If, at any time while this Preferred Stock is
        outstanding, the Corporation or any Subsidiary, as applicable, sells or grants
        any option to purchase or sells or grants any right to reprice its securities,
        or otherwise disposes of or issues (or announces any sale, grant or any option
        to purchase or other disposition) any Common Stock or Common Stock Equivalents
        entitling any Person to acquire shares of Common Stock at an effective price
        per
        share that is lower than the then Conversion Price (such lower price, the
        “Base Conversion Price” and such issuances collectively, a “Dilutive
        Issuance”) (if the holder of the Common Stock or Common Stock Equivalents so
        issued shall at any time, whether by operation of purchase price adjustments,
        reset provisions, floating conversion, exercise or exchange prices or otherwise,
        or due to warrants, options or rights per share which are issued in connection
        with such issuance, be entitled to receive shares of Common Stock at an
        effective price per share that is lower than the Conversion Price, such issuance
        shall be deemed to have occurred for less than the Conversion Price on such
        date
        of the Dilutive Issuance), then the Conversion Price shall be reduced to
        equal
        the Base Conversion Price.  Notwithstanding the foregoing, no
        adjustment will be made under this Section 7(b) in respect of an Exempt
        Issuance.  The Corporation shall notify the Holders in writing, no
        later than the Business Day following the issuance of any Common Stock or
        Common
        Stock Equivalents subject to this Section 7(b), indicating therein the
        applicable issuance price, or applicable reset price, exchange price, conversion
        price and other pricing terms (such notice, the “Dilutive Issuance
        Notice”).  For purposes of clarification, whether or not the
        Corporation provides a Dilutive Issuance Notice pursuant to this Section
        7(b),
        upon the occurrence of any Dilutive Issuance, the Holders are entitled to
        receive a number of Conversion Shares based upon the Base Conversion Price
        on or
        after the date of such Dilutive Issuance, regardless of whether a Holder
        accurately refers to the Base Conversion Price in the Notice of
        Conversion.

      

      c)           Subsequent
        Rights
        Offerings.  If the Corporation,
        at any
        time while the Preferred Stock is outstanding, shall issue rights, options
        or
        warrants to all holders of Common Stock (and not to Holders) entitling them
        to
        subscribe for or purchase shares of Common Stock at a price per share less
        than
        the VWAP at the record date mentioned below, then the Conversion Price shall
        be
        multiplied by a fraction, of which the denominator shall be the number of
        shares
        of the Common Stock outstanding on the date of issuance of such rights or
        warrants plus the number of additional shares of Common Stock offered for
        subscription or purchase, and of which the numerator shall be the number
        of
        shares of the Common Stock outstanding on the date of issuance of such rights
        or
        warrants plus the number of shares which the aggregate offering price of
        the
        total number of shares so offered (assuming receipt by the Corporation in
        full
        of all consideration payable upon exercise of such rights, options or warrants)
        would purchase at such VWAP.  Such adjustment shall be made whenever
        such rights or warrants are issued, and shall become effective immediately
        after
        the record date for the determination of stockholders entitled to receive
        such
        rights, options or warrants.

      

      d)           Pro
        Rata
        Distributions.  If the Corporation,
        at any
        time while Preferred Stock is outstanding, shall distribute to all holders
        of
        Common Stock (and not to Holders) evidences of its indebtedness or assets
        or
        rights or warrants to subscribe for or purchase any security, then in each
        such
        case the Conversion Price shall be determined by multiplying such Conversion
        Price in effect immediately prior to the record date fixed for determination
        of
        stockholders entitled to receive such distribution by a fraction of which
        the
        denominator shall be the VWAP determined as of the record date mentioned
        above,
        and of which the numerator shall be such VWAP on such record date less the
        then
        fair market value at such record date of the portion of such assets or evidence
        of indebtedness so distributed applicable to one outstanding share of the
        Common
        Stock as determined by the Board of Directors in good faith.  In
        either case the adjustments shall be described in a statement provided to
        the
        Holders of the portion of assets or evidences of indebtedness so distributed
        or
        such subscription rights applicable to one share of Common
        Stock.  Such adjustment shall be made whenever any such distribution
        is made and shall become effective immediately after the record date mentioned
        above.

      

      
        
          
          

        

        
          9

          
            

          

        

        
          
          

        

      

      e)           Fundamental
        Transaction.  If, at any time
        while this
        Preferred Stock is outstanding, (A) the Corporation effects any merger or
        consolidation of the Corporation with or into another Person, (B) the
        Corporation effects any sale of all or substantially all of its assets in
        one or
        a series of related transactions, (C) any tender offer or exchange offer
        (whether by the Corporation or another Person) is completed pursuant to which
        holders of Common Stock are permitted to tender or exchange their shares
        for
        other securities, cash or property, or (D) the Corporation effects any
        reclassification of the Common Stock or any compulsory share exchange pursuant
        to which the Common Stock is effectively converted into or exchanged for
        other
        securities, cash or property (in any such case, a “Fundamental
        Transaction”), then
        upon any subsequent conversion of this Preferred Stock, the Holders shall
        have
        the right to receive, for each Conversion Share that would have been issuable
        upon such conversion immediately prior to the occurrence of such Fundamental
        Transaction, the same kind and amount of securities, cash or property as
        it
        would have been entitled to receive upon the occurrence of such Fundamental
        Transaction if it had been, immediately prior to such Fundamental Transaction,
        the holder of one share of Common Stock (the “Alternate
        Consideration”).  For purposes of
        any such
        conversion, the determination of the Conversion Price shall be appropriately
        adjusted to apply to such Alternate Consideration based on the amount of
        Alternate Consideration issuable in respect of one share of Common Stock
        in such
        Fundamental Transaction, and the Corporation shall apportion the Conversion
        Price among the Alternate Consideration in a reasonable manner reflecting
        the
        relative value of any different components of the Alternate
        Consideration.  If holders of Common Stock are given any choice as to
        the securities, cash or property to be received in a Fundamental Transaction,
        then the Holders shall be given the same choice as to the Alternate
        Consideration it receives upon any conversion of this Preferred Stock following
        such Fundamental Transaction.  To the extent necessary to effectuate
        the foregoing provisions, any successor to the Corporation or surviving entity
        in such Fundamental Transaction shall file a new Certificate of Designation
        with
        the same terms and conditions and issue to the Holders new preferred stock
        consistent with the foregoing provisions and evidencing the Holders’ right to
        convert such preferred stock into Alternate Consideration.  The terms
        of any agreement pursuant to which a Fundamental Transaction is effected
        shall
        include terms requiring any such successor or surviving entity to comply
        with
        the provisions of this Section 7(e) and insuring that this Preferred Stock
        (or
        any such replacement security) will be similarly adjusted upon any subsequent
        transaction analogous to a Fundamental Transaction.

       

      f)           Exempt
        Issuance.  Notwithstanding the foregoing, no adjustment will be
        made under this Section 7 in respect of an Exempt Issuance.

      

      g)           Calculations.  All
        calculations under
        this Section 7 shall be made to the nearest cent or the nearest 1/100th of
        a
        share, as the case may be.  The number of shares of Common Stock
        outstanding at any given time shall not include shares owned or held by or
        for
        the account of the Corporation, and the description of any such shares of
        Common
        Stock shall be considered on issue or sale of Common Stock.  For
        purposes of this Section 7, the number of shares of Common Stock deemed to
        be
        issued and outstanding as of a given date shall be the sum of the number
        of
        shares of Common Stock (excluding treasury shares, if any) issued and
        outstanding.

      

      h)           Notice
        to Holders.

      

      i.           Adjustment
        to Conversion
        Price.  Whenever the Conversion
        Price is adjusted pursuant to any provisions of this Section 7, the Corporation
        shall promptly mail to each Holder a notice setting forth the Conversion
        Price
        after such adjustment and setting forth a brief statement of the facts requiring
        such adjustment.  If the Corporation issues a variable rate security,
        despite the prohibition thereon in the Purchase Agreement (or other Securities
        Purchase Agreement if applicable to a Holder), the Corporation shall be deemed
        to have issued Common Stock or Common Stock Equivalents at the lowest possible
        conversion or exercise price at which such securities may be converted or
        exercised in the case of a Variable Rate Transaction (as defined in the Purchase
        Agreement), or the lowest possible adjustment price in the case of an MFN
        Transaction (as defined in the Purchase Agreement).

      

      ii.           Notice
        to Allow Conversion by
        Holder.  If
        (A) the Corporation shall declare a dividend (or any other distribution)
        on the
        Common Stock; (B) the Corporation shall declare a special nonrecurring cash
        dividend on or a redemption of the Common Stock; (C) the Corporation shall
        authorize the granting to all holders of the Common Stock rights or warrants
        to
        subscribe for or purchase any shares of capital stock of any class or of
        any
        rights; (D) the approval of any stockholders of the Corporation shall be
        required in connection with any reclassification of the Common Stock, any
        consolidation or merger to which the Corporation is a party, any sale or
        transfer of all or substantially all of the assets of the Corporation, of
        any
        compulsory share exchange whereby the Common Stock is converted into other
        securities, cash or property; (E) the Corporation shall authorize the voluntary
        or involuntary dissolution, liquidation or winding up of the affairs of the
        Corporation; then, in each case, the Corporation shall cause to be filed
        at each
        office or agency maintained for the purpose of conversion of the Preferred
        Stock, and shall cause to be mailed to the Holders at their last addresses
        as
        they shall appear upon the stock books of the Corporation, at least 20 calendar
        days prior to the applicable record or effective date hereinafter specified,
        a
        notice stating (x) the date on which a record is to be taken for the purpose
        of
        such dividend, distribution, redemption, rights or warrants, or if a record
        is
        not to be taken, the date as of which the holders of the Common Stock of
        record
        to be entitled to such dividend, distributions, redemption, rights or warrants
        are to be determined or (y) the date on which such reclassification,
        consolidation, merger, sale, transfer or share exchange is expected to become
        effective or close, and the date as of which it is expected that holders
        of the
        Common Stock of record shall be entitled to exchange their shares of the
        Common
        Stock for securities, cash or other property deliverable upon such
        reclassification, consolidation, merger, sale, transfer or share exchange;
        provided,
        that the failure to mail such notice
        or any defect therein or in the mailing thereof shall not affect the validity
        of
        the corporate action required to be specified in such notice.  Holders
        are entitled to convert the Conversion Amount of Preferred Stock during the
        20-day period commencing the date of such notice to the effective date of
        the
        event triggering such notice.

      Section
        8.  Forced Conversion.

       

      a)           As
        used herein, the “Forced Conversion Date” shall be the Plan Closing
        Date.

       

      b)           One
        minute after this Second Amended and Restated Certificate is effective with
        the
        Nevada Secretary of State (the "Conversion Time") on the Forced Conversion
        Date,
        each share of Preferred Stock outstanding, automatically and without any
        action
        on the part of the holder thereof, shall convert into a number of fully paid
        and
        nonassessable shares of Common Stock equal to the quotient of (i) the Stated
        Value of the shares of Preferred Stock outstanding on the Forced Conversion
        Date
        divided by (ii) the Conversion Price in effect at the Conversion Time on
        the
        Forced Conversion Date.  Any accrued but unpaid dividends on the

        9.  Redemption Upon Triggering Events.

      

      a)           “Triggering
        Event” means any one
        or more of the
        following events (whatever the reason and whether it shall be voluntary or
        involuntary or effected by operation of law or pursuant to any judgment,
        decree
        or order of any court, or any order, rule or regulation of any administrative
        or
        governmental body):

      

      i.           the
        failure of a Conversion Shares
        Registration Statement to be declared effective by the Commission on or prior
        to
        the 210th
        day after the Original Issue
        Date;

       

      ii.           if,
        during the Effectiveness Period,
        the effectiveness of the Conversion Shares Registration Statement lapses
        for any
        reason for more than an aggregate of 25 calendar days (which need not be
        consecutive days) during any 12 month period, or the Holder shall not be
        permitted to resell Registrable Securities under the Conversion Shares
        Registration Statement for more than an aggregate of 25 calendar days (which
        need not be consecutive days) during any 12 month period, and in each case
        the
        shares of Common Stock into which such Holder’s Preferred Stock can be converted
        cannot be sold in the public securities market pursuant to Rule 144(k) under
        the
        Securities Act, provided, that the cause of such lapse or unavailability
        is not
        due to factors solely within the control of such holder of Preferred
        Stock;

      

      iii.           the
        Corporation shall fail to deliver
        certificates representing Conversion Shares issuable upon a conversion hereunder
        that comply with the provisions hereof prior to the 9th
        Trading Day after such shares are
        required to be delivered hereunder, or the Corporation shall provide written
        notice to any Holder, including by way of public announcement, at any time,
        of
        its intention not to comply with requests for conversion of any shares of
        Preferred Stock in accordance with the terms hereof;

      

      iv.           one
        of the Events (as defined in the
        Registration Rights Agreement) described in subsections (i), (ii) or (iii)
        of
        Section 2(b) of the Registration Rights Agreement shall not have been cured
        to
        the satisfaction of the Holders prior to the expiration of 30 days from the
        Event Date (as defined in the Registration Rights Agreement) relating thereto
        (other than an Event resulting from a failure of a Conversion Shares
        Registration Statement to be declared effective by the Commission on or prior
        to
        the 210th day after the Original Issue Date, which shall be covered by Section
        9(a)(i));

      

      v.           the
        Corporation shall fail for any
        reason to pay in full the amount of cash due pursuant to a Buy-In within
        15 days
        after notice therefor is delivered hereunder or shall fail to pay all amounts
        owed on account of an Event within 15 days of the date due;

      

      vi.           the
        Corporation shall fail to have
        available a sufficient number of authorized and unreserved shares of Common
        Stock to issue to such Holder upon a conversion hereunder;

      

      vii.           the
        Corporation shall fail to observe
        or perform any other covenant, agreement or warranty contained in, or otherwise
        commit any breach of the Transaction Documents, and such failure or breach
        shall
        not, if subject to the possibility of a cure by the Corporation, have been
        remedied within 30 calendar days after the date on which written notice of
        such
        failure or breach shall have been given;

      

      
        
          
          

        

        
          11

          
            

          

        

        
          
          

        

      

      viii.           the
        Corporation shall redeem more than
        a de minimis
        number of Junior Securities other than
        as to repurchases of Common Stock or Common Stock Equivalents from departing
        officers and directors of the Corporation, provided that, while any of the
        Preferred Stock remains outstanding, such repurchases shall not exceed an
        aggregate of $100,000 from all officers and directors;

      

      ix.           the
        Corporation shall be party to a
        Change of Control Transaction;

      

      x.           there
        shall have occurred a Bankruptcy
        Event; or

      

      xi.           the
        Common Stock shall fail to be
        listed or quoted for trading on a Trading Market for more than 7 Trading
        Days,
        which need not be consecutive Trading Days.

      

      b)           Upon
        the occurrence of a Triggering
        Event, each Holder shall (in addition to all other rights it may have hereunder
        or under applicable law) have the right, exercisable at the sole option of
        such
        Holder, to require the Corporation to redeem all of the Preferred Stock then
        held by such Holder for a redemption price, in cash, equal to the Triggering
        Redemption Amount.  The Triggering Redemption Amount shall be due and
        payable within 5 Trading Days of the date on which the notice for the payment
        therefor is provided by a Holder (the “Triggering Redemption
        Payment
        Date”).  If
        the Corporation fails to pay the Triggering Redemption Amount hereunder in
        full
        pursuant to this Section on the date such amount is due in accordance with
        this
        Section, the Corporation will pay interest thereon at a rate of 18% per annum
        (or such lesser amount permitted by applicable law), accruing daily from
        such
        date until the Triggering Redemption Amount, plus all such interest thereon,
        is
        paid in full.  For purposes of this Section, a share of Preferred
        Stock is outstanding until such date as the Holder shall have received
        Conversion Shares upon a conversion (or attempted conversion) thereof that
        meets
        the requirements hereof or has been paid the Triggering Redemption Amount
        plus
        all accrued but unpaid dividends and all accrued but unpaid liquidated damages
        in cash.

       

      Section
        10.  Miscellaneous.

      

      a)           No
        Debt.  So long as at
        least 5 shares of
        Preferred Stock are outstanding, the Corporation will not and will not permit
        any of its Subsidiaries to directly or indirectly enter into, create, incur,
        assume or suffer to exist (or allow any of its Subsidiaries to do so) any
        indebtedness or liens of any kind on or with respect to any of its property
        or
        assets now owned or hereafter acquired or any interest therein or any income
        or
        profits therefrom, other than (1) accounts payable, equipment leases, other
        current payables and other accrued liabilities incurred in connection with
        short-term operating liabilities, (2) accrued interest on the Corporation’s
        existing indebtedness as set forth on Schedule 10 hereto, and (3) up to
        $2,000,000 for non-equity linked debt financing.

      

      b)           Notices.  Any
        and all notices or
        other communications or deliveries to be provided by the Holders hereunder,
        including, without limitation, any Notice of Conversion, shall be in writing

        other communications or deliveries to be provided by the Corporation hereunder
        shall be in writing and delivered personally, by facsimile, sent by a nationally
        recognized overnight courier service addressed to each Holder at the facsimile
        telephone number or address of such Holder appearing on the books of the
        Corporation, or if no such facsimile telephone number or address appears,
        at the
        principal place of business of the Holder.  Any notice or other
        communication or deliveries hereunder shall be deemed given and effective
        on the
        earliest of (i) the date of transmission, if such notice or communication
        is

      c)           Absolute
        Obligation.  Except as expressly
        provided herein, no provision of this Certificate of Designation shall alter
        or
        impair the obligation of the Corporation, which is absolute and unconditional,
        to pay the liquidated damages (if any) on, the shares of Preferred Stock
        at the
        time, place, and rate, and in the coin or currency, herein
        prescribed.

      

      d)           Lost
        or Mutilated Preferred Stock
        Certificate.  If a Holder’s Preferred
        Stock certificate shall be mutilated, lost, stolen or destroyed, the Corporation
        shall execute and deliver, in exchange and substitution for and upon
        cancellation of a mutilated certificate, or in lieu of or in substitution
        for a
        lost, stolen or destroyed certificate, a new certificate for the shares of
        Preferred Stock so mutilated, lost, stolen or destroyed but only upon receipt

        ownership hereof, and indemnity, if requested, all reasonably satisfactory
        to
        the Corporation.

      e)           Governing
        Law.  All questions
        concerning
        the construction, validity, enforcement and interpretation of this Certificate
        of Designation shall be governed by and construed and enforced in accordance
        with the internal laws of the State of New York, without regard to the
        principles of conflicts of law thereof.  Each party agrees that all
        legal proceedings concerning the interpretations, enforcement and defense
        of the
        transactions contemplated by any of the Transaction Documents (whether brought
        against a party hereto or its respective affiliates, directors, officers,
        shareholders, employees or agents) shall be commenced in the state and federal
        courts sitting in the City of New York, Borough of Manhattan (the “New York Courts”).  Each
        party hereto hereby
        irrevocably submits to the exclusive jurisdiction of the New York Courts
        for the
        adjudication of any dispute hereunder or in connection herewith or with any
        transaction contemplated hereby or discussed herein (including with respect
        to
        the enforcement of any of the Transaction Documents), and hereby irrevocably
        waives, and agrees not to assert in any suit, action or proceeding, any claim
        that it is not personally subject to the jurisdiction of any such court,
        or such
        New York Courts are improper or inconvenient venue for such
        proceeding.  Each party hereby irrevocably waives personal service of
        process and consents to process being served in any such suit, action or
        proceeding by mailing a copy thereof via registered or certified mail or
        overnight delivery (with evidence of delivery) to such party at the address
        in
        effect for notices to it under this Certificate of Designation and agrees
        that
        such service shall constitute good and sufficient service of process and
        notice
        thereof.  Nothing contained herein shall be deemed to limit in any way
        any right to serve process in any manner permitted by law.  Each party
        hereto hereby irrevocably waives, to the fullest extent permitted by applicable
        law, any and all right to trial by jury in any legal proceeding arising out
        of
        or relating to this Certificate of Designation or the transactions contemplated
        hereby.  If either party shall commence an action or proceeding to
        enforce any provisions of this Certificate of Designation, then the prevailing
        party in such action or proceeding shall be reimbursed by the other party
        for
        its attorneys fees and other costs and expenses incurred with the investigation,
        preparation and prosecution of such action or proceeding.

      

      f)           Waiver.  Any
        waiver by the
        Corporation or the Holder of a breach of any provision of this Certificate
        of
        Designation shall not operate as or be construed to be a waiver of any other
        breach of such provision or of any breach of any other provision of this
        Certificate of Designation.  The failure of the Corporation or the
        Holder to insist upon strict adherence to any term of this Certificate of
        Designation on one or more occasions shall not be considered a waiver or
        deprive
        that party of the right thereafter to insist upon strict adherence to that
        term
        or any other term of this Certificate of Designation.  Any waiver must
        be in writing.

      

      g)           Severability.  If
        any provision of this
        Certificate of Designation is invalid, illegal or unenforceable, the balance
        of
        this Certificate of Designation shall remain in effect, and if any provision
        is
        inapplicable to any Person or circumstance, it shall nevertheless remain
        applicable to all other Persons and circumstances.  If it shall be
        found that any interest or other amount deemed interest due hereunder violates
        applicable laws governing usury, the applicable rate of interest due hereunder
        shall automatically be lowered to equal the maximum permitted rate of
        interest.

      

      h)           Next
        Business Day.  Whenever any payment
        or
        other obligation hereunder shall be due on a day other than a Business Day,
        such
        payment shall be made on the next succeeding Business Day.

      

      i)           Headings.  The
        headings contained
        herein are for convenience only, do not constitute a part of this Certificate
        of
        Designation and shall not be deemed to limit or affect any of the provisions
        hereof.

      

      j)           Status
        of Converted or Redeemed
        Preferred Stock.  Shares of Preferred
        Stock
        may only be issued if permitted pursuant to the Purchase
        Agreement.  If any shares of Preferred Stock shall be converted,
        redeemed or reacquired by the Corporation, such shares shall resume the status
        of authorized but unissued shares of preferred stock and shall no longer
        be
        designated as Series C 7% Convertible Preferred Stock.

      THIS
        COMMON STOCK PURCHASE WARRANT (the “Warrant”) certifies that, for value
        received, ___________(the “Holder”), is entitled, upon the terms and
        subject to the limitations on exercise and the conditions hereinafter set
        forth,
        at any time on or after the original date of issuance (the “Initial Exercise
        Date”) and on or prior to the close of business on the fifth anniversary of
        the Initial Exercise Date (the “Termination Date”) but not thereafter, to
        subscribe for and purchase from Chembio Diagnostics, Inc., a Nevada corporation
        (the “Company”), up to __________ (__________) shares (the “Warrant
        Shares”) of Common Stock, par value $0.01 per share, of the Company (the
“Common Stock”).  The purchase price of one share of Common
        Stock under this Warrant shall be equal to the Exercise Price, as defined
        in
        Section 2(b).

      

      Section
        1.                                Definitions.  Capitalized
        terms used and not otherwise defined herein shall have the meanings set forth
        in
        that certain Securities Purchase Agreement (the “Purchase Agreement”),
        dated October 5, 2006, among the Company and the purchasers
        signatory thereto.

      

      Section
        2.                                Exercise.

       

      (a)           Exercise
        of the purchase rights represented by this Warrant may be made, in whole
        or in
        part, at any time or times on or after the Initial Exercise Date and on or
        before the Termination Date by delivery to the Company of a duly executed
        facsimile copy of the Notice of Exercise Form annexed hereto (or such other
        office or agency of the Company as it may designate by notice in writing
        to the
        registered Holder at the address of such Holder appearing on the books of
        the
        Company); and, within 3 Trading Days of the date said Notice of Exercise
        is
        delivered to the Company, the Company shall have received payment of the
        aggregate Exercise Price of the shares thereby purchased by wire transfer
        or
        cashier’s check drawn on a United States bank.  Notwithstanding
        anything herein to the contrary, the Holder shall not be required to physically
        surrender this Warrant to the Company until the Holder has purchased all
        of the
        Warrant Shares available hereunder and the Warrant has been exercised in
        full,
        in which case, the Holder shall surrender this Warrant to the Company for
        cancellation within 3 Trading Days of the date the final Notice of Exercise
        is
        delivered to the Company.  Partial exercises of this Warrant resulting
        in purchases of a portion of the total number of Warrant Shares available
        hereunder shall have the effect of lowering the outstanding number of Warrant
        Shares purchasable hereunder in an amount equal to the applicable number
        of
        Warrant Shares purchased.  The Holder and the Company shall maintain
        records showing the number of Warrant Shares purchased and the date of such
        purchases.  The Company shall deliver any objection to any Notice of
        Exercise Form within 1 Business Day of receipt of such notice.  In the
        event of any dispute or discrepancy, the records of the Holder shall be
        controlling and determinative in the absence of manifest error.  The
        Holder and any assignee, by acceptance of this Warrant, acknowledge and agree
        that, by reason of the provisions of this paragraph, following the purchase
        of a
        portion of the Warrant Shares hereunder, the number of Warrant Shares available
        for purchase hereunder at any given time may be less than the amount stated
        on
        the face hereof.

      

      (b)           The
        exercise price of the Common Stock under this Warrant shall be as follows,
        subject to adjustment hereunder (the “Exercise Price”):

       

      (i)           For
        the period 4:01p.m. eastern time (“ET”) through 9:59p.m. ET on the Plan
        Closing Date, $0.40 per share for all or any portion of this Warrant exercised
        for cash;

       

      (ii)           For
        the period 4:01p.m. ET through 9:59p.m. ET on the Plan Closing Date, $0.45
        per
        share for all or any portion of this Warrant exercised through a Cashless
        Exercise;

       

      (iii)           For
        the period beginning 10:00p.m. ET on the Plan Closing Date through 9:59p.m.
        ET
        on the Final Plan Date, $0.45 for all or any part of this Warrant exercised
        by a
        Holder who exercised at least 10% of all of such Holder’s warrants and options
        for cash at the Plan Closing Date;

       

      (iv)           For
        the period beginning 10:00p.m. ET on the Plan Closing Date, $1.00 per share
        for
        any Holder that did not exercise at least 10% of all of such Holder’s warrants
        and options for cash at an exercise price of $0.40 per share at the Plan
        Closing
        Date; and

       

      (v)           For
        the period beginning 10:00p.m. ET on the Final Plan Date, $1.00 per share
        for
        all or any portion of this Warrant that has not been exercised on or before
        9:59p.m. ET on the Final Plan Date.

       

      (c)           Cashless
        Exercise.

       

      (i)           At
        the option of the Holder, this Warrant may be exercised by means of a “cashless
        exercise” (a “Cashless Exercise”) in which the Holder shall be entitled
        to receive a certificate for the number of Warrant Shares equal to the quotient
        obtained by dividing [(A-B) (X)] by (A), where:

       

      (A)
        =                      the
        VWAP for the ten-Trading Day period that ends on the first Trading Day
        immediately preceding the date of such election;

       

      (B)
        =                      the
        applicable Exercise Price of this Warrant in effect on the date of exercise,
        as
        adjusted; and

       

      (X)
        =                      the
        number of Warrant Shares issuable upon exercise of this Warrant in accordance
        with the terms of this Warrant by means of a cash exercise rather than a
        cashless exercise.

       

      (ii)           Notwithstanding
        anything herein to the contrary, for any Notice of Exercise Form dated on
        the
        Plan Closing Date received from a Holder who exercises its warrants on cashless
        basis at $0.45 per share before 10:00p.m. ET on the Plan Closing Date, the
        value
        of (A) in the equation set forth in Section 2(c)(i) above shall be equal
        to the
        greater of $0.53 or the VWAP for the ten-Trading Day period that ends on
        the
        second Trading Day prior to the date of the Notice of Exercise
        Form.

       

      (iii)           Notwithstanding
        anything herein to the contrary, for any Notice of Exercise Form dated between
        and inclusive of the Plan Closing Date and the Final Plan Date received from
        a
        Holder who exercises at least 10% of all of such Holder's warrants and options
        for cash before 10:00p.m. ET on the Plan Closing Date the value of (A) in
        the
        equation set forth in Section 2(c)(i) above shall be equal to the greater
        of
        $0.53 or the VWAP for the ten-Trading Day period that ends on the second
        Trading
        Day prior to the date of the Notice of Exercise Form.  Any Exercise
        Form dated on the Final Plan Date must be received by the Company within
        five
        Trading Days of the Final Plan Date to be effective.

       

      (iv)           Notwithstanding
        anything herein to the contrary, a Holder who does not exercise (i) at least
        10%
        of all of such Holder's warrants and options issued by the Company for cash
        at
        an exercise price of $0.40 per share before 10:00p.m. ET on the Plan Closing
        Date, or (ii) its warrants on cashless basis at $0.45 per share by 10:00p.m.
        ET
        on the Plan Closing Date, shall not be permitted to exercise its Warrants
        on a
        cashless basis pursuant to Section 2(c)(i) above until April 1,
        2008.

       

      (d)           The
        Company shall not effect any exercise of this Warrant, and a Holder shall
        not
        have the right to exercise any portion of this Warrant, pursuant to Section
        2(c)
        or otherwise, to the extent that after giving effect to such issuance after
        exercise as set forth on the applicable Notice of Exercise, such Holder
        (together with such Holder’s Affiliates, and any other person or entity acting
        as a group together with such Holder or any of such Holder’s Affiliates), as set
        forth on the applicable Notice of Exercise, would beneficially own in excess
        of
        the Beneficial Ownership Limitation (as defined below).  For purposes
        of the foregoing sentence, the number of shares of Common Stock beneficially
        owned by such Holder and its Affiliates shall include the number of shares
        of
        Common Stock issuable upon exercise of this Warrant with respect to which
        such
        determination is being made, but shall exclude the number of shares of Common
        Stock which would be issuable upon (A) exercise of the remaining, nonexercised
        portion of this Warrant beneficially owned by such Holder or any of its
        Affiliates and (B) exercise or conversion of the unexercised or nonconverted
        portion of any other securities of the Company (including, without limitation,
        any other Preferred Stock or Warrants) subject to a limitation on conversion
        or
        exercise analogous to the limitation contained herein beneficially owned
        by such
        Holder or any of its affiliates.  Except as set forth in the preceding
        sentence, for purposes of this Section 2(d)(i), beneficial ownership shall
        be
        calculated in accordance with Section 13(d) of the Exchange Act and the rules
        and regulations promulgated thereunder, it being acknowledged by a Holder
        that
        the Company is not representing to such Holder that such calculation is in
        compliance with Section 13(d) of the Exchange Act and such Holder is solely
        responsible for any schedules required to be filed in accordance
        therewith.  To the extent that the limitation contained in this
        Section 2(d) applies, the determination of whether this Warrant is exercisable
        (in relation to other securities owned by such Holder together with any
        Affiliates) and of which a portion of this Warrant is exercisable shall be
        in
        the sole discretion of a Holder, and the submission of a Notice of Exercise
        shall be deemed to be each Holder’s determination of whether this Warrant is
        exercisable (in relation to other securities owned by such Holder together
        with
        any Affiliates) and of which portion of this Warrant is exercisable, in each
        case subject to such aggregate percentage limitation, and the Company shall
        have
        no obligation to verify or confirm the accuracy of such
        determination.  In addition, a determination as to any group status as
        contemplated above shall be determined in accordance with Section 13(d) of
        the
        Exchange Act and the rules and regulations promulgated
        thereunder.  For purposes of this Section 2(d), in determining the
        number of outstanding shares of Common Stock, a Holder may rely on the number
        of
        outstanding shares of Common Stock as reflected in (x) the Company’s most recent
        Form 10-QSB or Form 10-KSB, as the case may be, (y) a more recent public
        announcement by the Company or (z) any other notice by the Company or the
        Company’s Transfer Agent setting forth the number of shares of Common Stock
        outstanding.  Upon the written or oral request of a Holder, the
        Company shall within two Trading Days confirm orally and in writing to such
        Holder the number of shares of Common Stock then outstanding.  In any
        case, the number of outstanding shares of Common Stock shall be determined
        after
        giving effect to the conversion or exercise of securities of the Company,
        including this Warrant, by such Holder or its Affiliates since the date as
        of
        which such number of outstanding shares of Common Stock was
        reported.  The “Beneficial Ownership Limitation” shall be 4.99%
        of the number of shares of the Common Stock outstanding immediately after
        giving
        effect to the issuance of shares of Common Stock issuable upon exercise of
        this
        Warrant.  The Beneficial Ownership Limitation provisions of this
        Section 2(d)(i) may be waived by such Holder, at the election of such Holder,
        upon not less than 61 days’ prior notice to the Company to change the Beneficial
        Ownership Limitation to 9.99% of the number of shares of the Common Stock
        outstanding immediately after giving effect to the issuance of shares of
        Common
        Stock upon exercise of this Warrant, and the provisions of this Section 2(d)
        shall continue to apply.  Upon such a change by a Holder of the
        Beneficial Ownership Limitation from such 4.99% limitation to such 9.99%
        limitation, the Beneficial Ownership Limitation may not be further waived
        by
        such Holder.  The provisions of this paragraph shall be construed and
        implemented in a manner otherwise than in strict conformity with the terms
        of
        this Section 2(d)(i) to correct this paragraph (or any portion hereof) which
        may
        be defective or inconsistent with the intended Beneficial Ownership Limitation
        herein contained or to make changes or supplements necessary or desirable
        to
        properly give effect to such limitation.  The limitations contained in
        this paragraph shall apply to a successor holder of this
        Warrant.  Notwithstanding anything set forth in this Section 2(d), the
        4.99% and 9.99% beneficial ownership limitations imposed by this Section
        2(d)
        shall not apply to Common Stock issuable upon the exercise of Warrants in
        connection with the Plan.

      

      (e)           Mechanics
        of Exercise.

      

      (i)           Authorization
        of Warrant Shares.  The Company covenants that all Warrant Shares
        which may be issued upon the exercise of the purchase rights represented
        by this
        Warrant will, upon exercise of the purchase rights represented by this Warrant,
        be duly authorized, validly issued, fully paid and nonassessable and free
        from
        all taxes, liens and charges in respect of the issue thereof (other than
        taxes
        in respect of any transfer occurring contemporaneously with such
        issue).

      

      (ii)           Delivery
        of Certificates Upon Exercise.  Certificates for shares purchased
        hereunder shall be transmitted by the transfer agent of the Company to the
        Holder by crediting the account of the Holder’s prime broker with the Depository
        Trust Company through its Deposit Withdrawal Agent Commission (“DWAC”)
        system if the Company is a participant in such system, and otherwise by physical
        delivery to the address specified by the Holder in the Notice of Exercise
        within
        3 Trading Days from the delivery to the Company of the Notice of Exercise
        Form,
        surrender of this Warrant and payment of the aggregate Exercise Price as
        set
        forth above (“Warrant Share Delivery Date”).  This Warrant
        shall be deemed to have been exercised on the date the Exercise Price is
        received by the Company.  The Warrant Shares shall be deemed to have
        been issued, and Holder or any other person so designated to be named therein
        shall be deemed to have become a holder of record of such shares for all
        purposes, as of the date the Warrant has been exercised by payment to the
        Company of the Exercise Price (or by cashless exercise, if permitted) and
        all
        taxes required to be paid by the Holder, if any, pursuant to Section 2(e)(vii)
        prior to the issuance of such shares, have been paid.

      

      (iii)           Delivery
        of New Warrants Upon Exercise.  If this Warrant shall have been
        exercised in part, the Company shall, at the time of delivery of the certificate
        or certificates representing Warrant Shares, deliver to Holder a new Warrant
        evidencing the rights of Holder to purchase the unpurchased Warrant Shares
        called for by this Warrant, which new Warrant shall in all other respects
        be
        identical with this Warrant.

      

      (iv)           Rescission
        Rights.  If the Company fails to cause its transfer agent to
        transmit to the Holder a certificate or certificates representing the Warrant
        Shares pursuant to this Section 2(e)(iv) by the Warrant Share Delivery Date,
        then the Holder will have the right to rescind such exercise.

      

      (v)           Compensation
        for Buy-In on Failure to Timely Deliver Certificates Upon
        Exercise.  In addition to any other rights available to the
        Holder, if the Company fails to cause its transfer agent to transmit to the
        Holder a certificate or certificates representing the Warrant Shares pursuant
        to
        an exercise on or before the Warrant Share Delivery Date, and if after such
        date
        the Holder is required by its broker to purchase (in an open market transaction
        or otherwise) or the Holder’s brokerage firm otherwise purchases shares of
        Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant
        Shares which the Holder anticipated receiving upon such exercise (a
“Buy-In”), then the Company shall (1) pay in cash to the Holder the
        amount by which (x) the Holder’s total purchase price (including brokerage
        commissions, if any) for the shares of Common Stock so purchased exceeds
        (y) the
        amount obtained by multiplying (A) the number of Warrant Shares that the
        Company
        was required to deliver to the Holder in connection with the exercise at
        issue
        times (B) the price at which the sell order giving rise to such purchase
        obligation was executed, and (2) at the option of the Holder, either reinstate
        the portion of the Warrant and equivalent number of Warrant Shares for which
        such exercise was not honored or deliver to the Holder the number of shares
        of
        Common Stock that would have been issued had the Company timely complied
        with
        its exercise and delivery obligations hereunder.  For example, if the
        Holder purchases Common Stock having a total purchase price of $11,000 to
        cover
        a Buy-In with respect to an attempted exercise of shares of Common Stock
        with an
        aggregate sale price giving rise to such purchase obligation of $10,000,
        under
        clause (1) of the immediately preceding sentence the Company shall be required
        to pay the Holder $1,000.  The Holder shall provide the Company
        written notice indicating the amounts payable to the Holder in respect of
        the
        Buy-In, together with applicable confirmations and other evidence reasonably
        requested by the Company.  Nothing herein shall limit a Holder’s right
        to pursue any other remedies available to it hereunder, at law or in equity
        including, without limitation, a decree of specific performance and/or
        injunctive relief with respect to the Company’s failure to timely deliver
        certificates representing shares of Common Stock upon exercise of the Warrant
        as
        required pursuant to the terms hereof.

      

      (vi)           No
        Fractional Shares or Scrip.  No fractional shares or scrip
        representing fractional shares shall be issued upon the exercise of this
        Warrant.  As to any fraction of a share which Holder would otherwise
        be entitled to purchase upon such exercise, the Company shall pay a cash
        adjustment in respect of such final fraction in an amount equal to such fraction
        multiplied by the Exercise Price.

      

      (vii)           Charges,
        Taxes and Expenses.  Issuance of certificates for Warrant Shares
        shall be made without charge to the Holder for any issue or transfer tax
        or
        other incidental expense in respect of the issuance of such certificate,
        all of
        which taxes and expenses shall be paid by the Company, and such certificates
        shall be issued in the name of the Holder or in such name or names as may
        be
        directed by the Holder; provided, however, that in the event
        certificates for Warrant Shares are to be issued in a name other than the
        name
        of the Holder, this Warrant when surrendered for exercise shall be accompanied
        by the Assignment Form attached hereto duly executed by the Holder; and the
        Company may require, as a condition thereto, the payment of a sum sufficient
        to
        reimburse it for any transfer tax incidental thereto.

      

      (viii)                      Closing
        of Books.  The Company will not close its stockholder books or
        records in any manner which prevents the timely exercise of this Warrant,
        pursuant to the terms hereof.

      

      (f)           For
        purposes of this warrant, the term “Plan” shall mean any action the
        Company takes, with any required approval of the holders thereof, on or before
        the Final Plan Date as contemplated by the Plan Summary and accompanying
        materials provided to holders on December 4, 2007, in connection with the
        reduction or other modification of terms of the Company’s then-outstanding
        preferred stock, warrants and options, including, but not limited to, actions
        the Company takes to (i) facilitate the conversion of the Series A, B and
        C
        Convertible Preferred Stock; (ii) reduce the exercise price of any of the
        Company’s outstanding warrants or options; (iii) offer the holders of the
        Company’s warrants and options the opportunity to exercise such warrants and
        options on a cash and/or cashless basis; and (iv) make other amendments to
        the
        documents governing these securities to effect these modifications, and to
        facilitate the conversion and exercise of these securities.

       

      (g)           “Plan
        Closing Date” shall be December 19, 2007.

       

      (h)           “Final
        Plan Date” shall mean the date that is six months and twelve days after the
        Plan Closing Date.

       

      Section
        3.                                Certain
        Adjustments.

      

      (a)           Stock
        Dividends and Splits.  If the Company, at any time while this
        Warrant is outstanding:  (A) pays a stock dividend or otherwise make a
        distribution or distributions on shares of its Common Stock or any other
        equity
        or equity equivalent securities payable in shares of Common Stock (which,
        for
        avoidance of doubt, shall not include any shares of Common Stock issued by
        the
        Company upon exercise of this Warrant, the Company’s Series A Convertible
        Preferred Stock, the Company’s Series B 9% Convertible Preferred Stock or the
        Company’s Series C 7% Convertible Preferred Stock), (B) subdivides outstanding
        shares of Common Stock into a larger number of shares, (C) combines (including
        by way of reverse stock split) outstanding shares of Common Stock into a
        smaller
        number of shares, or (D) issues by reclassification of shares of the Common
        Stock any shares of capital stock of the Company, then in each case the Exercise
        Price shall be multiplied by a fraction of which the numerator shall be the
        number of shares of Common Stock (excluding treasury shares, if any) outstanding
        immediately before such event and of which the denominator shall be the number
        of shares of Common Stock outstanding immediately after such event and the
        number of shares issuable upon exercise of this Warrant shall be proportionately
        adjusted.  Any adjustment made pursuant to this Section 3(a) shall
        become effective immediately after the record date for the determination
        of
        stockholders entitled to receive such dividend or distribution and shall
        become
        effective immediately after the effective date in the case of a subdivision,
        combination or re-classification.

       

      (b)           Subsequent
        Equity Sales.  If the Company or any Subsidiary thereof, as
        applicable, at any time while this Warrant is outstanding, shall offer, sell,
        grant any option to purchase or offer, sell or grant any right to reprice
        its
        securities, or otherwise dispose of or issue (or announce any offer, sale,
        grant
        or any option to purchase or other disposition) any Common Stock or Common
        Stock
        Equivalents entitling any Person to acquire shares of Common Stock, at an
        effective price per share less than the then Exercise Price (such lower price,
        the “Base Share Price” and such issuances collectively, a “Dilutive
        Issuance”), as adjusted hereunder (if the holder of the Common Stock or
        Common Stock Equivalents so issued shall at any time, whether by operation
        of
        purchase price adjustments, reset provisions, floating conversion, exercise
        or
        exchange prices or otherwise, or due to warrants, options or rights per share
        which are issued in connection with such issuance, be entitled to receive
        shares
        of Common Stock at an effective price per share which is less than the Exercise
        Price, such issuance shall be deemed to have occurred for less than the Exercise
        Price on such date of the Dilutive Issuance), then, the Exercise Price shall
        be
        reduced to equal the Base Share Price and the number of Warrant Shares issuable
        hereunder shall be increased such that the aggregate Exercise Price payable
        hereunder, after taking into account the decrease in the Exercise Price,
        shall
        be equal to the aggregate Exercise Price prior to such
        adjustment.  Such adjustment shall be made whenever such Common Stock
        or Common Stock Equivalents are issued.  The Company shall notify the
        Holder in writing, no later than the Trading Day following the issuance of
        any
        Common Stock or Common Stock Equivalents subject to this section, indicating
        therein the applicable issuance price, or of applicable reset price, exchange
        price, conversion price and other pricing terms (such notice the “Dilutive
        Issuance Notice”).  For purposes of clarification, whether or not
        the Company provides a Dilutive Issuance Notice pursuant to this Section
        3(b),
        upon the occurrence of any Dilutive Issuance, after the date of such Dilutive
        Issuance the Holder is entitled to receive a number of Warrant Shares based
        upon
        the Base Share Price regardless of whether the Holder accurately refers to
        the
        Base Share Price in the Notice of Exercise.

       

      (c)           Pro
        Rata Distributions.  If the Company, at any time prior to the
        Termination Date, shall distribute to all holders of Common Stock (and not
        to
        Holders of the Warrants) evidences of its indebtedness or assets or rights
        or
        warrants to subscribe for or purchase any security other than the Common
        Stock
        (which shall be subject to Section 3(b)), then in each such case the Exercise
        Price shall be adjusted by multiplying the Exercise Price in effect immediately
        prior to the record date fixed for determination of stockholders entitled
        to
        receive such distribution by a fraction of which the denominator shall be
        the
        VWAP determined as of the record date mentioned above, and of which the
        numerator shall be such VWAP on such record date less the then per share
        fair
        market value at such record date of the portion of such assets or evidence
        of
        indebtedness so distributed applicable to one outstanding share of the Common
        Stock as determined by the Board of Directors in good faith.  In
        either case the adjustments shall be described in a statement provided to
        the
        Holders of the portion of assets or evidences of indebtedness so distributed
        or
        such subscription rights applicable to one share of Common
        Stock.  Such adjustment shall be made whenever any such distribution
        is made and shall become effective immediately after the record date mentioned
        above.

       

      (d)           Fundamental
        Transaction.  If, at any time while this Warrant is outstanding,
        (A) the Company effects any merger or consolidation of the Company with or
        into
        another Person, (B) the Company effects any sale of all or substantially
        all of
        its assets in one or a series of related transactions, (C) any tender offer
        or
        exchange offer (whether by the Company or another Person) is completed pursuant
        to which holders of Common Stock are permitted to tender or exchange their
        shares for other securities, cash or property, or (D) the Company effects
        any
        reclassification of the Common Stock or any compulsory share exchange pursuant
        to which the Common Stock is effectively converted into or exchanged for
        other
        securities, cash or property (in any such case, a “Fundamental
        Transaction”), then, upon any subsequent exercise of this Warrant, the
        Holder shall have the right to receive, for each Warrant Share that would
        have
        been issuable upon such exercise immediately prior to the occurrence of such
        Fundamental Transaction, at the option of the Holder, (a) upon exercise of
        this
        Warrant, the number of shares of Common Stock of the successor or acquiring
        corporation or of the Company, if it is the surviving corporation and any
        additional consideration, and Alternate Consideration receivable upon or
        as a
        result of such reorganization, reclassification, merger, consolidation or
        disposition of assets by a Holder of the number of shares of Common Stock
        for
        which this Warrant is exercisable immediately prior to such event or (b)
        if the
        Company is acquired in an all cash transaction, cash equal to the value of
        this
        Warrant as determined in accordance with the Black-Scholes option pricing
        formula (the “Alternate Consideration”).  For purposes of any
        such exercise, the determination of the Exercise Price shall be appropriately
        adjusted to apply to such Alternate Consideration based on the amount of
        Alternate Consideration issuable in respect of one share of Common Stock
        in such
        Fundamental Transaction, and the Company shall apportion the Exercise Price
        among the Alternate Consideration in a reasonable manner reflecting the relative
        value of any different components of the Alternate Consideration.  If
        holders of Common Stock are given any choice as to the securities, cash or
        property to be received in a Fundamental Transaction, then the Holder shall
        be
        given the same choice as to the Alternate Consideration it receives upon
        any
        exercise of this Warrant following such Fundamental Transaction.  To
        the extent necessary to effectuate the foregoing provisions, any successor
        to
        the Company or surviving entity in such Fundamental Transaction shall issue
        to
        the Holder a new warrant consistent with the foregoing provisions and evidencing
        the Holder’s right to exercise such warrant into Alternate
        Consideration.  The terms of any agreement pursuant to which a
        Fundamental Transaction is effected shall include terms requiring any such
        successor or surviving entity to comply with the provisions of this Section
        3(d)
        and insuring that this Warrant (or any such replacement security) will be
        similarly adjusted upon any subsequent transaction analogous to a Fundamental
        Transaction.

       

      (e)           Exempt
        Issuance.  Notwithstanding the foregoing, no adjustments,
        Alternate Consideration nor notices shall be made, paid or issued under this
        Section 3 in respect of an Exempt Issuance, or in respect of any issuance
        of
        Common Stock or Common Stock Equivalents upon conversion of the preferred
        stock
        or the exercise of warrants and/or options in connection with the
        Plan.

       

      (f)           Calculations.  All
        calculations under this Section 3 shall be made to the nearest cent or the
        nearest 1/100th of a share, as the case may be.  The number of shares
        of Common Stock outstanding at any given time shall not include shares of
        Common
        Stock owned or held by or for the account of the Company, and the description
        of
        any such shares of Common Stock shall be considered on issue or sale of Common
        Stock.  For purposes of this Section 3, the number of shares of Common
        Stock deemed to be issued and outstanding as of a given date shall be the
        sum of
        the number of shares of Common Stock (excluding treasury shares, if any)
        issued
        and outstanding.

       

      (g)           Voluntary
        Adjustment By Company.  The Company may at any time during the
        term of this Warrant reduce the then current Exercise Price to any amount
        and
        for any period of time deemed appropriate by the Board of Directors of the
        Company.

       

      (h)           Notice
        to Holders.

       

      (i)           Adjustment
        to Exercise Price.  Whenever the Exercise Price is adjusted
        pursuant to this Section 3, the Company shall promptly mail to each Holder
        a
        notice setting forth the Exercise Price after such adjustment and setting
        forth
        a brief statement of the facts requiring such adjustment.  If the
        Company issues a variable rate security, despite the prohibition thereon
        in the
        Purchase Agreement, the Company shall be deemed to have issued Common Stock
        or
        Common Stock Equivalents at the lowest possible conversion or exercise price
        at
        which such securities may be converted or exercised in the case of a Variable
        Rate Transaction (as defined in the Purchase Agreement), or the lowest possible
        adjustment price in the case of an MFN Transaction (as defined in the Purchase
        Agreement.

      

      (ii)           Notice
        to Allow Exercise by Holder.  If (A) the Company shall declare a
        dividend (or any other distribution) on the Common Stock; (B) the Company
        shall
        declare a special nonrecurring cash dividend on or a redemption of the Common
        Stock; (C) the Company shall authorize the granting to all holders of the
        Common
        Stock rights or warrants to subscribe for or purchase any shares of capital
        stock of any class or of any rights; (D) the approval of any stockholders
        of the
        Company shall be required in connection with any reclassification of the
        Common
        Stock, any consolidation or merger to which the Company is a party, any sale
        or
        transfer of all or substantially all of the assets of the Company, of any
        compulsory share exchange whereby the Common Stock is converted into other
        securities, cash or property; (E) the Company shall authorize the voluntary
        or
        involuntary dissolution, liquidation or winding up of the affairs of the
        Company; then, in each case, the Company shall cause to be mailed to the
        Holder
        at its last address as it shall appear upon the Warrant Register of the Company,
        at least 20 calendar days prior to the applicable record or effective date
        hereinafter specified, a notice stating (x) the date on which a record is
        to be
        taken for the purpose of such dividend, distribution, redemption, rights
        or
        warrants, or if a record is not to be taken, the date as of which the holders
        of
        the Common Stock of record to be entitled to such dividend, distributions,
        redemption, rights or warrants are to be determined or (y) the date on which
        such reclassification, consolidation, merger, sale, transfer or share exchange
        is expected to become effective or close, and the date as of which it is
        expected that holders of the Common Stock of record shall be entitled to
        exchange their shares of the Common Stock for securities, cash or other property
        deliverable upon such reclassification, consolidation, merger, sale, transfer
        or
        share exchange; provided, that the failure to mail such notice or any
        defect therein or in the mailing thereof shall not affect the validity of
        the
        corporate action required to be specified in such notice.  The Holder
        is entitled to exercise this Warrant during the 20-day period commencing
        on the
        date of such notice to the effective date of the event triggering such
        notice.

      

      Section
        4.                                Transfer
        of Warrant.

      

      (a)           Transferability.  Subject
        to compliance with any applicable securities laws and the conditions set
        forth
        in Sections 5(a) and 4(d) hereof and to the provisions of Section 4.1 of
        the
        Purchase Agreement, this Warrant and all rights hereunder are transferable,
        in
        whole or in part, upon surrender of this Warrant at the principal office
        of the
        Company, together with a written assignment of this Warrant substantially
        in the
        form attached hereto duly executed by the Holder or its agent or attorney
        and
        funds sufficient to pay any transfer taxes payable upon the making of such
        transfer.  Upon such surrender and, if required, such payment, the
        Company shall execute and deliver a new Warrant or Warrants in the name of
        the
        assignee or assignees and in the denomination or denominations specified
        in such
        instrument of assignment, and shall issue to the assignor a new Warrant
        evidencing the portion of this Warrant not so assigned, and this Warrant
        shall
        promptly be cancelled.  A Warrant, if properly assigned, may be
        exercised by a new holder for the purchase of Warrant Shares without having
        a
        new Warrant issued.

       

      (b)           New
        Warrants.  This Warrant may be divided or combined with other
        Warrants upon presentation hereof at the aforesaid office of the Company,
        together with a written notice specifying the names and denominations in
        which
        new Warrants are to be issued, signed by the Holder or its agent or
        attorney.  Subject to compliance with Section 4(a), as to any transfer
        which may be involved in such division or combination, the Company shall
        execute
        and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants
        to
        be divided or combined in accordance with such notice.

       

      (c)           Warrant
        Register.  The Company shall register this Warrant, upon records
        to be maintained by the Company for that purpose (the “Warrant
        Register”), in the name of the record Holder hereof from time to
        time.  The Company may deem and treat the registered Holder of this
        Warrant as the absolute owner hereof for the purpose of any exercise hereof
        or
        any distribution to the Holder, and for all other purposes, absent actual
        notice
        to the contrary.

       

      (d)           Transfer
        Restrictions.  If, at the time of the surrender of this Warrant in
        connection with any transfer of this Warrant, the transfer of this Warrant
        shall
        not be registered pursuant to an effective registration statement under the
        Securities Act and under applicable state securities or blue sky laws, the
        Company may require, as a condition of allowing such transfer (i) that the
        Holder or transferee of this Warrant, as the case may be, furnish to the
        Company
        a written opinion of counsel (which opinion shall be in form, substance and
        scope customary for opinions of counsel in comparable transactions) to the
        effect that such transfer may be made without registration under the Securities
        Act and under applicable state securities or blue sky laws, (ii) that the
        holder
        or transferee execute and deliver to the Company an investment letter in
        form
        and substance acceptable to the Company and (iii) that the transferee be
        an
“accredited investor” as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7), or
        (a)(8) promulgated under the Securities Act or a qualified institutional
        buyer
        as defined in Rule 144A(a) promulgated under the Securities Act.

       

      Section
        5.                                Miscellaneous.

      

      (a)           Title
        to Warrant.  Prior to the Termination Date and subject to
        compliance with applicable laws and Section 4 of this Warrant, this Warrant
        and
        all rights hereunder are transferable, in whole or in part, at the office
        or
        agency of the Company by the Holder in person or by duly authorized attorney,
        upon surrender of this Warrant together with the Assignment Form annexed hereto
        properly endorsed.  The transferee shall sign an investment letter in
        form and substance reasonably satisfactory to the Company.

       

      (b)           No
        Rights as Shareholder Until Exercise.  This Warrant does not
        entitle the Holder to any voting rights or other rights as a shareholder
        of the
        Company prior to the exercise hereof.  Upon the surrender of this
        Warrant and the payment of the aggregate Exercise Price (or by means of a
        cashless exercise), the Warrant Shares so purchased shall be and be deemed
        to be
        issued to such Holder as the record owner of such shares as of the close
        of
        business on the later of the date of such surrender or payment.

       

      (c)           Loss,
        Theft, Destruction or Mutilation of Warrant.  The Company
        covenants that upon receipt by the Company of evidence reasonably satisfactory
        to it of the loss, theft, destruction or mutilation of this Warrant or any
        stock
        certificate relating to the Warrant Shares, and in case of loss, theft or
        destruction, of indemnity or security reasonably satisfactory to it (which,
        in
        the case of the Warrant, shall not include the posting of any bond), and
        upon
        surrender and cancellation of such Warrant or stock certificate, if mutilated,
        the Company will make and deliver a new Warrant or stock certificate of like
        tenor and dated as of such cancellation, in lieu of such Warrant or stock
        certificate.

       

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

       

      (e)           Authorized
        Shares.  The Company covenants that during the period the Warrant
        is outstanding, it will reserve from its authorized and unissued Common Stock
        a
        sufficient number of shares to provide for the issuance of the Warrant Shares
        upon the exercise of any purchase rights under this Warrant.  The
        Company further covenants that its issuance of this Warrant shall constitute
        full authority to its officers who are charged with the duty of executing
        stock
        certificates to execute and issue the necessary certificates for the Warrant
        Shares upon the exercise of the purchase rights under this
        Warrant.  The Company will take all such reasonable action as may be
        necessary to assure that such Warrant Shares may be issued as provided herein
        without violation of any applicable law or regulation, or of any requirements
        of
        the Trading Market upon which the Common Stock may be listed.

       

      Except
        and to the extent as waived or consented to by the Holder, the Company shall
        not
        by any action, including, without limitation, amending its certificate of
        incorporation or through any reorganization, transfer of assets, consolidation,
        merger, dissolution, issue or sale of securities or any other voluntary action,
        avoid or seek to avoid the observance or performance of any of the terms
        of this
        Warrant, but will at all times in good faith assist in the carrying out of
        all
        such terms and in the taking of all such actions as may be necessary or
        appropriate to protect the rights of Holder as set forth in this Warrant
        against
        impairment.  Without limiting the generality of the foregoing, the
        Company will (a) not increase the par value of any Warrant Shares above the
        amount payable therefor upon such exercise immediately prior to such increase
        in
        par value, (b) take all such action as may be necessary or appropriate in
        order
        that the Company may validly and legally issue fully paid and nonassessable
        Warrant Shares upon the exercise of this Warrant, and (c) use commercially
        reasonable efforts to obtain all such authorizations, exemptions or consents
        from any public regulatory body having jurisdiction thereof as may be necessary
        to enable the Company to perform its obligations under this
        Warrant.

       

      Before
        taking any action which would result in an adjustment in the number of Warrant
        Shares for which this Warrant is exercisable or in the Exercise Price, the
        Company shall obtain all such authorizations or exemptions thereof, or consents
        thereto, as may be necessary from any public regulatory body or bodies having
        jurisdiction thereof.

       

      (f)           Jurisdiction.  All
        questions concerning the construction, validity, enforcement and interpretation
        of this Warrant shall be determined in accordance with the provisions of
        the
        Purchase Agreement.

       

      (g)           Restrictions.  The
        Holder acknowledges that the Warrant Shares acquired upon the exercise of
        this
        Warrant, if not registered, will have restrictions upon resale imposed by
        state
        and federal securities laws.

       

      (h)           Nonwaiver
        and Expenses.  No course of dealing or any delay or failure to
        exercise any right hereunder on the part of Holder shall operate as a waiver
        of
        such right or otherwise prejudice Holder’s rights, powers or remedies,
        notwithstanding the fact that all rights hereunder terminate on the Termination
        Date.  If the Company willfully and knowingly fails to comply with any
        provision of this Warrant, which results in any material damages to the Holder,
        the Company shall pay to Holder such amounts as shall be sufficient to cover
        any
        costs and expenses including, but not limited to, reasonable attorneys’ fees,
        including those of appellate proceedings, incurred by Holder in collecting
        any
        amounts due pursuant hereto or in otherwise enforcing any of its rights,
        powers
        or remedies hereunder.

       

      (i)           Notices.  Any
        notice, request or other document required or permitted to be given or delivered
        to the Holder by the Company shall be delivered in accordance with the notice
        provisions of the Purchase Agreement.

       

      (j)           Limitation
        of Liability.  No provision hereof, in the absence of any
        affirmative action by Holder to exercise this Warrant or purchase Warrant
        Shares, and no enumeration herein of the rights or privileges of Holder,
        shall
        give rise to any liability of Holder for the purchase price of any Common
        Stock
        or as a stockholder of the Company, whether such liability is asserted by
        the
        Company or by creditors of the Company.

       

      (k)           Remedies.  Holder,
        in addition to being entitled to exercise all rights granted by law, including
        recovery of damages, will be entitled to specific performance of its rights
        under this Warrant.  The Company agrees that monetary damages would
        not be adequate compensation for any loss incurred by reason of a breach
        by it
        of the provisions of this Warrant and hereby agrees to waive the defense
        in any
        action for specific performance that a remedy at law would be
        adequate.

       

      (l)           Successors
        and Assigns.  Subject to applicable securities laws, this Warrant
        and the rights and obligations evidenced hereby shall inure to the benefit
        of
        and be binding upon the successors of the Company and the successors and
        permitted assigns of Holder.  The provisions of this Warrant are
        intended to be for the benefit of all Holders from time to time of this Warrant
        and shall be enforceable by any such Holder or holder of Warrant
        Shares.

       

      (m)           Amendment.  This
        Warrant may be modified or amended or the provisions hereof waived with the
        written consent of the Company and the Holder.

       

      (n)           Severability.  Wherever
        possible, each provision of this Warrant shall be interpreted in such manner
        as
        to be effective and valid under applicable law, but if any provision of this
        Warrant shall be prohibited by or invalid under applicable law, such provision
        shall be ineffective to the extent of such prohibition or invalidity, without
        invalidating the remainder of such provisions or the remaining provisions
        of
        this Warrant.

       

      (o)           Headings.  The
        headings used in this Warrant are for the convenience of reference only and
        shall not, for any purpose, be deemed a part of this Warrant.
