        Exercise.

       

      a)      
        Exercise
        of Warrant.
        Exercise of the purchase rights represented by this Warrant may be made 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); provided,
        however,
        within
        5 Trading Days of the date said Notice of Exercise is delivered to the Company,
        the Holder shall have surrendered this Warrant to the Company and the Company
        shall

       

      
        
          
          

        

        
          1

          
            

          

        

        
          
          

        

      

       

      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. 

       

      b)        
        Exercise
        Price.
        The
        exercise price of the Common Stock under this Warrant shall be $3.25, subject
        to
        adjustment hereunder (the “Exercise
        Price”).

       

      c)        
        Net
        Exercise.
        In lieu
        of the payment methods set forth in Section 2(a) above and subject
        to
        Section 2(d)(3)(iii) below, commencing on October 26, 2005, 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 on the Trading Day immediately preceding
        the date
        of such election;

      

      (B)
        =    the Exercise Price of this Warrant, 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.

      

      d)        
        Exercise
        Limitations.
        

       

      i.     
        Holder’s
        Restrictions.
        The
        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, the Holder (together with the Holder’s
        affiliates), as set forth on the applicable Notice of Exercise, would
        beneficially own in excess of 9.99% of the number of shares of the Common
        Stock
        outstanding immediately after giving effect to such issuance.  For
        purposes
        of the foregoing sentence, the number of shares of Common Stock beneficially
        owned by the Holder and its affiliates shall include the number of shares
        of
        Common Stock issuable upon exercise of this Warrant with respect to which
        the
        determination of such sentence is being made.  Except as set forth
        in the
        preceding sentence, for purposes of this Section 2(d), beneficial ownership
        shall be calculated in accordance with Section 13(d) of the Exchange Act,
        it
        being acknowledged by Holder that the Company is not representing to Holder
        that
        such calculation is in compliance with Section 13(d) of the Exchange Act
        and
        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 the Holder) and of which portion
        of
        this Warrant is exercisable shall be in the sole discretion of such Holder,
        and
        the submission of a Notice of Exercise shall be deemed to be such Holder’s
        determination of whether this Warrant is exercisable (in relation to other
        securities owned by such Holder) 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 

       

      
        
          
          

        

        
          2

          
            

          

        

        
          
          

        

      

       

      to
        verify
        or confirm the accuracy of such determination. For purposes of this Section
        2(d), in determining the number of outstanding shares of Common Stock, the
        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
        the
        Holder, the Company shall within two Trading Days confirm orally and in writing
        to the 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 the Holder or its affiliates since the date as
        of
        which such number of outstanding shares of Common Stock was reported. The
        provisions of this Section 2(d) may be waived by the Holder upon, at the
        election of the Holder, not less than 61 days’ prior notice to the Company, and
        the provisions of this Section 2(d) shall continue to apply until such
        61st day (or such later date, as determined by the Holder, as may
        be
        specified in such notice of waiver).

       

      ii.     
        Trading
        Market Restrictions.
        If the
        Company has not obtained Shareholder Approval (as defined below) if required,
        then the Company may not issue upon exercise of this Warrant in the aggregate,
        in excess of 19.999% of the number of shares of Common Stock outstanding
        on the
        Trading Day immediately preceding the Closing Date, less any shares of Common
        Stock issued upon conversion of or as payment of dividends on the Preferred
        Stock or upon prior exercise of this or any other Warrant issued pursuant
        to the
        Purchase Agreement (such number of shares, the “Issuable
        Maximum”).
        If on
        any attempted exercise of this Warrant, the issuance of Warrant Shares would
        exceed the Issuable Maximum and the Company shall not have previously obtained
        the vote of shareholders (the “Shareholder
        Approval”),
        if
        any, as may be required by the applicable rules and regulations of the Trading
        Market (or any successor entity) to approve the issuance of shares of Common
        Stock in excess of the Issuable Maximum pursuant to the terms hereof, then
        the
        Company shall issue to the Holder requesting a Warrant exercise such number
        of
        Warrant Shares as may be issued below the Issuable Maximum and, with respect
        to
        the remainder of the aggregate number of Warrant Shares, this Warrant shall
        not
        be exercisable until and unless Shareholder Approval has been obtained.

       

      iii.     
        Restriction
        on “Net” Exercise.
        Notwithstanding any other provision of this Certificate, Holder shall only
        be
        permitted to effect a “net” exercise of the Warrants if on the date of exercise
        a registration statement permitting the Holder to resell the shares of Common
        Stock issuable upon the exercise of the Warrants is required to be effective
        and
        is not then effective or the prospectus forming a part of such
        registration

       

      
        
          
          

        

        
          3

          
            

          

        

        
          
          

        

      

       

      statement
        is not then available to be used by the Holder for the resale of the shares
        of
        Common Stock issuable upon the exercise of the Warrants. 

       

      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). 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.

       

      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 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,

       

      
        
          
          

        

        
          4

          
            

          

        

        
          
          

        

      

       

      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.     
        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.

       

      v.     
        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.

       

      vi.     
        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.

       

      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 pursuant to this Warrant), (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 before such event and of which the denominator
        shall
        be the number of shares of Common Stock outstanding 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

       

      
        
          
          

        

        
          5

          
            

          

        

        
          
          

        

      

       

      shall
        become effective immediately after the effective date in the case of a
        subdivision, combination or re-classification.

       

      b)       
        Subsequent
        Equity Sales.
        Other
        than pursuant to an Exempt Issuance, for the twelve (12) month period beginning
        on the effective date of the Registration Statement registering the resale
        of
        the Warrant Shares by the Holder, if the Company shall sell or grant any
        option
        to purchase or otherwise dispose of or issue 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 is 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),
        then, the Exercise Price shall be reduced by multiplying the Exercise Price
        by a
        fraction, the numerator of which is the number of shares of Common Stock
        issued
        and outstanding immediately prior to the Dilutive Issuance plus the number
        of
        shares of Common Stock and Common Stock Equivalents which the aggregate
        consideration received or receivable by the Corporation in connection with
        such
        Dilutive Issuance would purchase at the then effective Exercise Price, and
        the
        denominator of which shall be the sum of the number of shares of Common Stock
        issued and outstanding immediately prior to the Dilutive Issuance plus the
        number of shares of Common Stock and Common Stock Equivalents so issued or
        issuable in connection with the Dilutive Issuance. 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, 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

       

      
        
          
          

        

        
          6

          
            

          

        

        
          
          

        

      

       

      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)       
        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 includes 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.

       

      e)        
        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. 

       

      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 addresses as it shall appear upon the Warrant
        Register of the Company, at least 10 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

       

      
        
          
          

        

        
          7

          
            

          

        

        
          
          

        

      

       

      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
        10-day period commencing the date of such notice to the effective date of
        the
        event triggering such notice.

       

      f)        
        Reorganizations,
        Etc.
        In case,
        at any time during the Exercise Period, of any capital reorganization, of
        any
        reclassification of the stock of the Company (other than a change in par
        value
        or from par value to no par value or from no par value to par value or as
        a
        result of a stock dividend or subdivision, split-up or combination of shares),
        or the consolidation or merger of the Company with or into another corporation
        (other than a consolidation or merger in which the Company is the continuing
        operation and which does not result in any change or reclassification in
        the
        Warrant Shares) or of the sale of all or substantially all the properties
        and
        assets of the Company as an entirety to any other corporation, the Company,
        at
        its sole discretion, shall have the right and option to (A) provide 10 days
        prior written notice of such event to the Holder and this Warrant shall
        terminate and be of no further force and effect on and after the effective
        date
        of such capital reorganization or reclassification or the consummation of
        such
        consolidation, sale or merger; or (B) provide that this Warrant shall, after
        such reorganization, reclassification, consolidation, merger or sale, be
        exercisable for the kind and number of shares of stock or other securities
        or
        property of the Company or of the corporation resulting from such consolidation
        or surviving such merger or to which such properties and assets shall have
        been
        sold to which such holder would have been entitled if he, she or it had held
        the
        Warrant Shares issuable upon the exercise hereof immediately prior to such
        reorganization, reclassification, consolidation, merger or sale.

       

      g)        
        Exempt
        Issuance.
        Notwithstanding the foregoing, no adjustments, nor notices shall be made,
        paid
        or issued under this Section 3 in respect of an Exempt Issuance.

       

      h)        
        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.

       

      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

       

      
        
          
          

        

        
          8

          
            

          

        

        
          
          

        

      

       

      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) 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

       

      
        
          
          

        

        
          9

          
            

          

        

        
          
          

        

      

       

      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

       

      
        
          
          

        

        
          10

          
            

          

        

        
          
          

        

      

       

      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.

    COMMON
      STOCK WARRANT 

     

    THIS
      CERTIFIES
      that, for value received, __________ and its permitted transferees hereunder
      (the “Holder”), is entitled to subscribe for and purchase from XENOMICS,
      INC.,
      a Florida corporation (the “Company”), up to _____ fully paid and nonassessable
      shares (the “Warrant Shares”) of common stock, $.0001 par value, of the Company
      (the “Common Stock”) at $3.25
      per share (the “Warrant Price”) subject to adjustment as provided in Section 2
      hereof, at any time or from time to time during the period (the “Exercise
      Period”) commencing on the date hereof and ending on July 13, 2010.

     

    SECTION
      1. Exercise
      of Warrant.

     

    (a)       
      General.
      This
      Warrant may be exercised by the Holder as to the whole or any lesser number
      of
      the Warrant Shares covered hereby, upon surrender of this Warrant to the Company
      at its principal executive office together with the Notice of Exercise attached
      hereto as Exhibit A, duly completed and executed by the Holder, and
      payment
      to the Company of the aggregate Exercise Price for the Warrant Shares to be
      purchased in the form of (i) a check made payable to the Company,
      (ii) wire transfer according to the Company’s instructions or
      (iii) any combination of (i) and (ii). The exercise of this Warrant
      shall
      be deemed to have been effected on the day on which the Holder surrenders this
      Warrant to the Company and satisfies all of the requirements of this
      Section 1. Upon such exercise, the Holder will be deemed a shareholder
      of
      record of those Warrant Shares for which the warrant has been exercised with
      all
      rights of a shareholder (including, without limitation, all voting rights with
      respect to such Warrant Shares and all rights to receive any dividends with
      respect to such Warrant Shares). If this Warrant is to be exercised in respect
      of less than all of the Warrant Shares covered hereby, the Holder shall be
      entitled to receive a new warrant covering the number of Warrant Shares in
      respect of which this Warrant shall not have been exercised and for which it
      remains subject to exercise. Such new warrant shall be in all other respects
      identical to this Warrant.

     

    (b)       
      Net
      Issue Exercise.
      In lieu
      of exercising this Warrant via cash payment, the Holder may elect to receive
      shares equal to the value of this Warrant (or the portion thereof being
      canceled) by surrender of this Warrant at the principal office of the Company
      together with a Notice of Exercise duly executed and completed indicating
      payment pursuant to this Section 1(b), in which event the Company shall issue
      to
      the Holder a number of shares of Common Stock of the Company computed using
      the
      following formula:

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    X
      =
Y
      (A -
      B)

               
      A

    

    
      	
              Where

            	
              X

            	
              =

            	
              the
                number of Warrant Shares to be issued to the
                Holder.

            

    

    

    
      	 	
              Y

            	
              =

            	
              the
                number of Warrant Shares purchasable under this Warrant or, if only
                a
                portion of the Warrant is being exercised, the portion of the Warrant
                being cancelled (at the date of such
                calculation).

            

    

     

    
      	
            	
              A

            	
              =

            	
              the
                Fair Market Value (as defined below) of one Warrant Share (at the
                date of
                such calculation).

            

    

     

    
      	 	
              B

            	
              =

            	
              the
                Exercise Price (as adjusted to the date of such
                calculation).

            

    

    

    If
      the
      above calculation results in a negative number, then no shares of Common Stock
      shall be issued or issuable upon conversion of this Warrant.

    

    (c)       
      Fair
      Market Value.
      For
      purposes of this Section 1, the Fair Market Value of one Warrant Share
      shall be determined by the Company’s Board of Directors in good faith; provided,
      however, that where there exists a public market for the Common Stock at the
      time of such exercise, the fair market value per Warrant Share shall be the
      average of the closing bid and asked prices of the Common Stock quoted in the
      Over-The-Counter Market Summary or the last reported sale price of the Common
      Stock or the closing price quoted on the Nasdaq National Market or on any
      exchange on which the Common Stock is listed, whichever is applicable, as
      published in The
      Wall Street Journal
      for the
      five trading days prior to the date of determination of Fair Market
      Value.

     

    SECTION
      2. Adjustment
      of Warrant Price.
      If,
      at
      any time during the Exercise Period, the number of outstanding shares of Common
      Stock is (i) increased by a stock dividend payable in shares of Common Stock
      or
      by a subdivision or split of shares of such class of Common Stock, or (ii)
      decreased by a combination or reverse split of shares of Common Stock, then,
      following the record date fixed for the determination of holders of Common
      Stock
      entitled to receive the benefits of such stock dividend, subdivision, split-up,
      reverse split-up or combination, the Warrant Price shall be proportionately
      reduced, in the case of an increase in shares of Common Stock outstanding,
      or
      proportionately increased, in the case of a decrease in shares of Common Stock
      outstanding, in both cases by the ratio which the total number of shares of
      Common Stock to be outstanding immediately after such event bears to the total
      number of shares of Common Stock outstanding immediately prior to such
      event.

     

    SECTION
      3. Adjustment
      of Warrant Shares.
      Upon
      each
      adjustment of the Warrant Price as provided in Section 2, the Holder shall
      thereafter be entitled to subscribe for and purchase, at the Warrant Price
      resulting from such adjustment, the number of Warrant Shares equal to the
      product of (i) the number of Warrant Shares existing prior to such adjustment
      and (ii) the quotient obtained by dividing (A) the Warrant Price existing prior
      to such adjustment by (B) the new Warrant Price resulting from such adjustment.
      No fractional shares of capital stock of the Company shall be issued as a result
      of any such adjustment, and any fractional shares resulting

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    from
      the
      computations pursuant to this paragraph shall be eliminated without
      consideration.

     

    SECTION
      4. No
      Shareholder Rights.
      This
      Warrant shall not entitle the holder hereof to any voting rights or other rights
      as a shareholder of the Company.

     

    SECTION
      5. Covenant
      of the Company.
      The
      Company covenants and agrees that the Company shall at all times have authorized
      and reserved or shall authorize and reserve, free from preemptive rights, a
      sufficient number of shares of its Common Stock to provide for the exercise
      of
      the rights represented by this Warrant.

     

    SECTION
      6. Investment
      Representations and Warranties.
      The
      Holder hereby represents and warrants to the Company as follows:

     

    (a)       
      The
      Holder is acquiring the Warrant, and it will acquire the Common Stock issuable
      upon exercise thereof, for its own account, for investment and not with a view
      to the distribution thereof, nor with any present intention of distributing
      the
      same. The Holder understands that the Warrant and Common Stock issuable upon
      exercise thereof, will not be registered under the Act or registered or
      qualified under any state securities or “blue-sky” laws, by reason of their
      issuance in a transaction exempt from the registration and/or qualification
      requirements thereof, and that they must be held indefinitely unless a
      subsequent disposition thereof is registered under the Act or registered or
      qualified under any applicable state securities or “blue-sky” laws or is exempt
      from registration and/or qualification.

     

    (b)       
      The
      Holder understands that the exemption from registration afforded by Rule 144
      (the provisions of which are known to the Holder) promulgated under the Act
      depends on the satisfaction of various conditions and that, if applicable,
      Rule
      144 may only afford the basis for sales under certain circumstances only in
      limited amounts.

     

    (c)       
      The
      Holder has no need for liquidity in its investment in the Company, and is able
      to bear the economic risk of such investment for an indefinite period and to
      afford a complete loss thereof. 

     

    (d)       
      The
      Holder is an “accredited purchaser” as such term is defined in Rule 501 (the
      provisions of which are known to the Holder) promulgated under the
      Act.

     

    SECTION
      7. Restrictions
      on Transfer.
      The
      Holder of this Warrant by acceptance hereof agrees that the transfer of this
      Warrant and the shares of Common Stock issuable upon exercise of this Warrant
      are subject to the following provisions:

     

    (a)       
      General.
      Subject
      to the requirements of the Act or any applicable state securities laws, the
      Holder may sell, assign, transfer or otherwise dispose of all or any portion
      of
      the Warrants or the Warrant Shares acquired upon any exercise hereof at any
      time
      and from time to time. Upon the sale, assignment, transfer or other disposition
