      For
        good
        and valuable consideration, the receipt of which is hereby acknowledged by
        NANOSENSORS,
        INC., a
        Nevada
        corporation (the “Company”),
        

      (the

        is
        hereby granted ________ Warrants representing in the aggregate the right
        to
        purchase, at any time on and after the date on which the Series A Convertible

        Company's Common Stock, par value $.001 per share (“Common
        Stock”),
        until
        5:00 P.M., New York City time, on January 16, 2013 (the “Warrant

        to

       

      ______________________________________________________
        (______________) fully-paid and non-assessable shares of Common
        Stock.

       

      This
        Warrant is one of a duly authorized issue of 3,100,000 Warrants (each Warrant
        constituting a right to purchase 112.77066 shares of Common Stock at the
        Exercise Price as defined below), issued by the Company in exchange for
        6,200,000 Common Stock Purchase Warrants issued by CUCHULAINN
        HOLDINGS, INC., a
        Panamanian corporation (“Holdings”),
        originally in connection with a private offering of its securities (the
“Offering”).
        This
        Warrant was issued pursuant to the provisions of Section 2(g)(i) of the
        Agreement and Plan of Merger, dated as of November 27, 2007, as amended,
        by and
        among the Company, CUCHULAINN
        ACQUISITION, INC., a
        Panamanian corporation and wholly-owned subsidiary of the Company
        (“Acquisition”), and Holdings, as amended (the “Merger
        Agreement”)
        providing for the merger of Holdings with and into Acquisition with Acquisition
        as the surviving corporation (the “Merger”).
        The
        Warrants are similar in terms except for dates, amounts and named holders.
        

       

      l. Exercise
        of Warrant

       

      1.1  Exercise
        Procedure. This
        Warrant is exercisable at a price of $0.0088676 per share of Common
        Stock
        (the
“Exercise
        Price”
        subject
        to adjustment as provided in Section
        2
        hereof,
        payable in cash or by certified or official bank check in New York Clearing
        House funds. Upon surrender of this warrant certificate with the annexed
        Warrant
        Exercise Form duly executed, together with payment of the Exercise Price
        for the
        shares of Common Stock purchased at the Company’s principal executive offices,
        the registered Holder of the Warrant shall be entitled to receive a certificate
        or certificates for the shares of Common Stock so purchased (the “Warrant
        Shares”).
        The
        purchase rights represented by this Warrant are exercisable
        at the option of the Holder hereof, in whole or in part (but not as to
        fractional shares of the Common Stock) during any period in which this Warrant
        may be exercised as set forth above. In the case of the purchase of less
        than
        all the shares of Common Stock purchasable under this Warrant, the Company
        shall
        cancel this Warrant upon the surrender thereof and, upon the written request
        of
        the Holder, the Company shall execute and deliver a new Warrant of like tenor
        for the balance of the shares of Common Stock purchasable hereunder. In no
        event
        will this Warrant be exercisable prior to the Company amending its Articles
        of
        Incorporation so as to increase the number of authorized shares of Common
        Stock
        or to effect a 100-to-1 reverse stock split following consummation of the
        Merger.

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      1.2  Issuance
        of Warrant Shares. The
        issuance of certificates for shares of Common Stock upon the exercise
        of this Warrant shall be made without charge to the Holder hereof including,
        without limitation, any tax which may be payable in respect of the issuance
        thereof, and such certificates shall be issued in the name of, or in such
        names
        as may be directed by, the Holder hereof; provided, however, that the Company
        shall not be required to pay any tax which may be payable in respect of any
        transfer involved in the issuance and delivery of such certificate in a name
        other than that of the Holder and the Company shall not be required to issue
        or
        deliver such certificates unless or until the person or persons requesting
        the
        issuance thereof shall have paid to the Company the amount of such tax or
        shall
        have established to the satisfaction of the Company that such tax has been
        paid.

       

      1.3 
        Cashless Exercise.
        With
        respect to the Warrant Shares, in the event that a
        registration statement filed by the Company with the United States Securities
        and Exchange Commission for the purpose of registering the shares of Common
        Stock issuable upon exercise of this Warrant under the Act, has been declared
        effective by said Commission and thereafter the Company fails to maintain
        the
        effectiveness of such registration statement, the Holder may, during any
        period
        in which the registration statement has ceased to be effective, pay the Exercise
        Price through a cashless exercise (a “Cashless
        Exercise”),
        as
        hereinafter provided. The Holder may effect a Cashless Exercise by surrendering
        this Warrant to the Company and noting on the Exercise Notice that the Holder
        wishes to effect a Cashless Exercise, upon which the Company shall issue
        to the
        Holder the number of Warrant Shares determined as follows:

       

      X
        = Y x
        (A - B)/A

      where:

      X
        = the
        number of Warrant Shares to be issued to the Holder;

      Y
        = the
        number of Warrant Shares with respect to which this Warrant is being
        exercised;

      A
        = the
        Market Price (as defined below) as of the Exercise Date; and

      B
        = the
        Exercise Price.

       

      For
        purposes of Rule 144 promulgated under the Act, it is intended and acknowledged
        that the Warrant Shares issued in a Cashless Exercise transaction shall be
        deemed to have been acquired by the Holder, and the holding period for the
        Warrant Shares required by said Rule 144 shall be deemed to have been commenced,
        on the date this Warrant was originally issued by the Company. Except as
        otherwise defined herein, “Market
        Price”
means,
        as of a particular date, the average of the (i) high and low price of the
        Common
        Stock (if the Common Stock is not at that time listed for trading on a
        securities exchange) or (ii) closing price (if the Common Stock is traded
        on a
        securities exchange) for the ten (10) consecutive Trading Days occurring
        immediately prior to (but not including) any given date, as reported in the
        principal market on which the Company’s Common Stock is traded. In case any
        Common Stock or other securities which are convertible or exchangeable into
        Common Stock (collectively, “Common
        Stock Equivalents”)
        are
        issued in connection with any merger or consolidation in which the Company
        is
        the surviving corporation, the amount of consideration therefor will be deemed
        to be the fair market value of such portion of the net assets and business
        of
        the non-surviving corporation as is attributable to such Common Stock or
        Common
        Stock Equivalents. The Company’s Board of Directors shall calculate reasonably
        and in good faith, using standard commercial valuation methods appropriate
        for
        valuing such assets, the fair market value of any consideration other than
        cash
        or securities. If the Common Stock is not listed or admitted to trade on
        a
        national securities exchange and if bid and asked prices for the Common Stock
        are not furnished by the OTCBB, Pink Sheets or a similar organization, the
        “Market Value” shall be the value established in good faith by the Board of
        Directors taking into account such facts and circumstances deemed to be material
        by the independent members of the Board of Directors.

       

      
        
          
          

        

        
          2

          
            

          

        

        
          
          

        

      

       

      1.4  Reservation
        of Shares.
        Subject
        to amending
        its Articles of Incorporation so as to increase its number of authorized
        shares
        of Common Stock or alternatively effecting a reverse stock split of its Common
        Stock, the Company covenants that it will at all times reserve and keep
        available out of its authorized Common Stock, solely for the purpose of issuance
        upon exercise of this Warrant as herein provided, such number of shares of
        Common Stock as shall then be issuable upon the exercise of this Warrant.
        The
        Company covenants that all shares of Common Stock which shall be so issuable
        shall be duly and validly issued and fully-paid and non-assessable. The Company
        further covenants to act promptly to effect the aforesaid amendment of its
        articles of incorporation.

       

      2. Adjustments
        to Exercise Price

       

      2.1  Stock
        Dividends, Subdivisions, Reclassifications or Combinations.
        If
        the
        Corporation shall (A) declare a dividend or make a distribution on its Common
        Stock in shares of its Common Stock, (B) subdivide or reclassify the outstanding
        shares of Common Stock into a greater number of shares, or (C) combine or
        reclassify the outstanding Common Stock into a smaller number of shares,
        the
        Exercise Price in effect at the time of the record date for such dividend
        or
        distribution or the effective date of such subdivision, combination or
        reclassification shall be proportionately adjusted and the Holder, after
        such
        date, shall be entitled to receive the number of shares of Common Stock which
        he
        would have owned or been entitled to receive had this Warrant been exercised
        immediately prior to such date; provided that any adjustment made herein
        that results in a decrease (or increase) in the Exercise Price shall also
        effect
        a proportional increase (or decrease) in the number of shares of Common Stock
        into which this Warrant is exercisable. Successive adjustments in the Exercise
        Price shall be made whenever any event specified above shall occur.

       

      2.2  Consolidation,
        Merger, Sale or Conveyance.
        In case
        of any consolidation
        or merger of the Company with any other corporation (other than a wholly
        owned
        subsidiary), or in case of sale or transfer of all or substantially all of
        the
        assets of the Company, or in the case of any share exchange whereby the Common
        Stock is converted into other securities or property, the Company will be
        required to make appropriate provision so that the Holder will have the right
        thereafter to exercise this Warrant into the kind and amount of shares of
        stock
        and other securities and property receivable upon such consolidation, merger,
        sale, transfer or share exchange by a holder of the number of shares of Common
        Stock for which this Warrant was exercisable immediately prior to such
        consolidation, merger, sale, transfer or share exchange. Any adjustment made
        herein that results in a decrease in the Exercise Price shall also effect
        a
        proportional increase in the number of shares of Common Stock into which
        this
        Warrant is exercisable.

      2.3
         Notices
        of Change.
        Upon
        any determination or adjustment in the number
        or
        class of shares subject to this Warrant and of the Exercise Price, the Company
        shall give written notice thereof to the Holder, setting forth in reasonable
        detail and certifying the calculation of such determination or adjustment.
        The
        Company shall give written notice to the Holder at least 20 business days
        prior
        to the date on which the Company closes its books or takes a record for
        determining rights to receive any dividends or distributions or in the event
        of
        a merger, acquisition, consolidation, sale of all or substantially all of
        its
        assets or similar such event.

       

      2.4 Exceptions
        to Adjustment of Exercise Price.
        Notwithstanding the foregoing, no adjustment to the Exercise Price shall
        be made
        pursuant to this Section
        2
        upon the
        issuance of any Excluded Securities. For purposes hereof, “Excluded
        Securities”
means
        (A) shares of Common Stock issuable or issued to (x) employees or directors
        from time to time either directly or upon the exercise of options, in such
        case
        granted or to be granted in the discretion of the Board of Directors, pursuant
        to one or more stock option plans or stock purchase plans adopted
        by the Company, or (y) to consultants or vendors, either directly or pursuant
        to
        warrants or other convertible securities to acquire shares of Common Stock
        that
        are outstanding on the date hereof or issued hereafter; (B) shares of Common
        Stock issued in connection with any Common Stock Equivalents outstanding
        on the
        date hereof; (C) shares of Common Stock or Common Stock Equivalents issued
        to third parties in connection with a joint venture, strategic alliance or
        other
        commercial relationship with such third party relating to the operation of
        the
        Company’s business, the primary purpose of which is not to raise equity
        capital.

       

      3. Restrictions
        on Transfer

       

      The
        Holder acknowledges that he has been advised by the Company that this Warrant
        and the shares of Common Stock (the “Warrant
        Shares” and
        collectively with this Warrant, the “Securities”)
        have
        not been registered under the Act, that the Warrant is being issued, and
        the
        shares issuable upon exercise of the Warrant will be issued, on the basis
        of the
        statutory exemption provided by Section 4(2) of the Act relating to transactions
        by an issuer not involving any public offering, and that the Company’s reliance
        upon this statutory exemption is based in part upon the representations made
        by
        the Holder contained herein. The Holder acknowledges that he has been informed
        by the Company of, or is otherwise familiar with, the nature of the limitations
        imposed by the Act and the rules and regulations thereunder on the transfer
        of
        securities. In particular, the Holder agrees that no sale, assignment or
        transfer of the Securities shall be valid or effective, and the Company shall
        not be required to give any effect to any such sale, assignment or transfer,
        unless (i) the sale, assignment or transfer of the Securities is registered
        under the Act, and the Company has no obligations or intention to so register
        the Securities except as may otherwise be provided herein, or (ii) the
        Securities are sold, assigned or transferred in accordance with all the
        requirements and limitations of Rule 144 under the Act or such sale, assignment,
        or transfer is otherwise exempt
        from registration under the Act. The Holder represents and warrants that
        he has
        acquired this Warrant and will acquire the Warrant Shares for his own account
        for investment and not with a view to the sale or distribution thereof or
        the
        granting of any participation therein, and that he has no present intention
        of
        distributing or selling to others any of such interest or granting any
        participation therein. The Holder acknowledges that the securities shall
        bear
        the following legend:

       

      
        
          
          

        

        
          4

          
            

          

        

        
          
          

        

      

       

      THESE
        SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
        AMENDED
        (THE “ACT”). SUCH SECURITIES MAY NOT BE SOLD OR OFFERED FOR SALE, TRANSFERRED,
        HYPOTHECATED OR OTHERWISE ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
        STATEMENT WITH RESPECT THERETO UNDER SUCH ACT OR AN OPINION OF COUNSEL TO
        THE
        COMPANY THAT AN EXEMPTION FROM REGISTRATION FOR SUCH SALE, OFFER, TRANSFER,
        HYPOTHECATION OR OTHER ASSIGNMENT IS AVAILABLE UNDER SUCH
        ACT.

       

      4.  Registration
        Rights.
        

       

      The
        Holder shall be entitled to all of the rights and subject to all of the
        obligations regarding registration of the Warrant Shares, as described in
        the
        Registration Rights Agreement between the Company and the original holder
        hereof
        relating to this Warrant and the Warrant Shares.

       

      5.  Exercise
        Limitation. 

       

      In
        no
        event shall a Holder be permitted to exercise this
        Warrant, or part hereof, if, upon such exercise, the number of shares of
        Common
        Stock beneficially owned by the Holder (other than shares which would otherwise
        be deemed beneficially owned except for being subject to a limitation on
        conversion or exercise analogous to the limitation contained in this
Section
        5),
        would
        exceed 4.99% of the number of shares of Common Stock then issued and
        outstanding; provided that the foregoing limitation shall not apply with
        respect
        to the original Holder hereof who received this Warrant upon the closing
        of the
        Merger. As used herein, beneficial ownership shall be determined in accordance
        with Section 13(d) of the Securities Exchange Act of 1934, as amended, and
        the
        rules thereunder. To the extent that the limitation contained in this
Section
        5
        applies,
        the submission of an Exercise Notice by the Holder shall be deemed to be
        the
        Holder’s representation that this Warrant is exercisable pursuant to the terms
        hereof and the Company shall be entitled to rely on such representation without
        making any further inquiry as to whether this Section
        5
        applies.
        Nothing contained herein shall be deemed to restrict the right of a Holder
        to
        exercise this Warrant, or part thereof, at such time as such exercise will
        not
        violate the provisions of this Section
        5.
        The
        limitations contained in this Section
        5
        shall
        cease to apply (x) upon sixty (60) days’ prior written notice from the Holder to
        the Company, or (y) immediately upon written notice from the Holder to the
        Company at any time after the public announcement or other disclosure of
        the (i)
        sale, conveyance or disposition of all or substantially all of the assets
        of the
        Company; (ii) effectuation of a transaction or series of transactions in
        which
        more than 50% of the voting power of the Company is disposed of (other than
        as a

      6.  Redemption. 

       

      This
        Warrant may be redeemed at the option of the Company,
        at a redemption price of $0.01 per Warrant (the “Redemption
        Price”),
        at any
        time commencing twelve months after the effective date of the Registration
        Statement and the Expiration Date upon not less than 30 days (and not more
        than
        60 days) written notice delivered to the Holder, provided: (a) the closing
        bid
        price of the Common Stock is been at least 175% of the Exercise Price for
        twenty
        (20) consecutive trading days prior to the date of the notice of redemption
        and
        (b) there is an effective registration statement with a current prospectus
        available covering the shares of Common Stock issuable upon exercise of this
        Warrant. On and after the date fixed for redemption, the Holder shall have
        no
        rights with respect to this Warrant except to receive the Redemption Price
        per
        Warrant upon surrender of this Certificate. The Company covenants and agrees
        that it will honor all Exercise Notices tendered through the 5:00 Eastern
        Time
        on the Business Day immediately preceding the Redemption Date. The redemption
        payment shall be made in cash on the date fixed for redemption in the Company’s
        notice of redemption, as described below (the “Redemption
        Date”).
        The
        notice of redemption shall specify: (i) the Redemption Price; (ii) the
        Redemption Date; (iii) the place where Warrant Certificates shall be delivered
        and the redemption price paid; and (iv) that the right to exercise the Warrants
        shall terminate at 5:00 p.m. Eastern Time on the Business Day immediately
        preceding the Redemption Date. An affidavit of the Secretary or an Assistant
        Secretary of the Company that notice of redemption has been mailed shall,
        in the
        absence of fraud, be conclusive evidence of the facts stated therein. For
        purposes of this Warrant, a “Business Day” means any day other than a Saturday,
        Sunday or a day on which the New York Stock Exchange or banking institutions
        located in the State of New York are authorized or required by law or other
        governmental action to close.

       

      From
        and
        after the Redemption Date, the Company shall, at the place specified in the
        notice of redemption, upon presentation and surrender to the Company by or
        on
        behalf of the Holder thereof of this Warrant, deliver or cause to be delivered
        to or upon the written order of such holder a sum of cash equal to the
        Redemption Price of each such Warrant. From and after the Redemption Date
        and
        upon the deposit or setting aside by the Company of a sum sufficient to redeem
        all the Warrants called for redemption, such Warrants shall expire and become
        void and all rights hereunder and shall cease, except the right, if any,
        to
        receive payment of the Redemption Price.

      7.  Exchange
        and Replacement of Warrant Certificates.

       

      This
        Warrant Certificate is exchangeable without expense, upon the surrender hereof
        by the registered Holder at the principal executive office of the Company,
        for a
        new Warrant Certificate of like tenor and date representing in the aggregate
        the
        right to purchase the same number of Warrant Shares in such denominations
        as
        shall be designated by the Holder thereof at the time of such
        surrender.

       

      Upon
        receipt by the Company of evidence reasonably satisfactory to it of the loss,
        theft, destruction or mutilation of this Warrant Certificate, and, in case
        of
        loss, theft or destruction, of indemnity or security reasonably satisfactory
        to
        it, and reimbursement to the Company of all reasonable expenses incidental
        thereto, and upon surrender and cancellation of the Warrants, if mutilated,
        the
        Company will make and deliver a new Warrant of like tenor, in lieu thereof
        and
        any such lost, stolen, destroyed or mutilated warrant shall thereupon become
        void.

       

      8.  Elimination
        of Fractional Interests.

       

      The
        Company shall not be required to issue certificates representing fractions
        of
        the shares of Common Stock and shall not be required to issue scrip or pay
        cash
        in lieu of fractional interests, it being the intent of the parties that
        all
        fractional interests shall be eliminated by requiring warrants to be exercised
        in pairs in order to purchase one full share of common stock for the Exercise
        Price.

       

      9.  Rights
        of Warrant Holders.

       

      Nothing
        contained in this Agreement shall be construed as conferring upon the Holder
        any
        rights whatsoever as a stockholder of the Company, either at law or in equity,
        including without limitation, or Holders the right to vote or to consent
        or to

        matter.

      The Company shall (a) register and qualify the Registrable Securities
covered
      by any Registration Statement under the securities laws of such jurisdictions

      Securities reasonably requests, (b) prepare and file in those jurisdictions
      such
      amendments (including post-effective amendments) and supplements to such
      registrations and qualifications as may be necessary to maintain the
      effectiveness thereof and availability for use during the Registration Period,

      registrations and qualifications in effect at all times during the Registration
      Period, and (d) take all other actions reasonably necessary or advisable to

      be required to qualify but for this Section 3.4, (ii) subject itself to general
      taxation in any such jurisdiction or (iii) file a general consent to service
      of
      process in any such jurisdiction.

      and after the date of this Agreement, the Company shall not enter into any
      agreement granting any holder or prospective holder of any securities of the
      Company registration rights with respect to such securities without the prior
      written consent of the holders of more than 50% of the Registrable Securities
      then outstanding, unless such new registration rights, including standoff
      obligations, are subordinate to the rights of the Securityholders
      hereunder.

     

    3.6 Correction
      of Statements or Omissions. As soon as practicable after becoming aware
      of
      any event, of which the Company has actual knowledge, as a result of which
      the
      prospectus included in a Registration Statement, as then in effect, includes
      an
      untrue statement of a material fact or fails to state a material fact required
      to be stated therein or necessary to make the statements therein not misleading,
      the Company shall publicly announce or notify all Selling Securityholders of
      the
      happening of such event, and shall use commercially reasonable efforts as soon
      as possible to (but in any event it shall within five (5) Business Days or
      three
      (3) Business Days of the receipt by the Company from its accountants of
      financial information required to correct such untrue statement or omission,
      as
      applicable) prepare a supplement or amendment to the Registration Statement
      (and
      make all required filings with the SEC and all applicable state securities
      or
      blue sky commissions) to correct such untrue statement or omission if not
      otherwise satisfied through the filing of a report to the SEC or otherwise
      pursuant to applicable securities laws (but such supplement or amendment or
      other filing shall not be required if, notwithstanding the Company’s
      commercially reasonable efforts so to prepare and file such supplement,
      amendment or other filing, such supplement, amendment or other filing is no
      longer required by applicable law to correct such untrue statement or omission
      because such untrue statement or omission no longer exists); and the Company
      shall simultaneously (and thereafter as requested) deliver such number of copies
      of such supplement or amendment to each Selling Securityholder (or other
      applicable document) as such Securityholder may request in writing.

     

    3.7 Stop
      Orders. The Company shall use commercially reasonable efforts to prevent
the
      issuance of any stop order or other suspension of effectiveness of a
      Registration Statement, and, if such an order is issued, to obtain the
      withdrawal of such order at the earliest practicable time, and the Company
      shall
      immediately notify all Selling Securityholders and, in the event of an
      underwritten offering, the managing underwriter(s), of the issuance of such
      order and the resolution thereof.

      Registration Statement
      within ten (10) Business Days after receipt thereof to the extent practicable
      and if not practicable, as quickly as possible acting with diligence, and
      thereafter request effectiveness of the Registration Statement within five
      (5)
      Business Days of receipt of a “no review” or “no further comments”
notification.

     

    3.9 Inspection
      of Records.
      The
      Company shall provide each Selling Securityholder, and any underwriter who
      may
      participate in the distribution of Registrable Securities, and their respective
      representatives, the opportunity to conduct a reasonable inquiry of the

      the Selling Securityholders and any such underwriter shall hold in confidence
      and shall not make any disclosure of any record or other information which
      the
      Company determines in good faith to be confidential, and of which determination
      the inspectors are so notified in writing, unless (a) the disclosure of such
      records is necessary to avoid or correct a misstatement or omission in any
      Registration Statement, (b) the release of such records is ordered pursuant
      to a
      subpoena or other order from a court or government body of competent
      jurisdiction or is otherwise required by applicable law or legal process, or
      (c)
      the information in such records has been made generally available to the public
      other than by disclosure in violation of this or any other agreement (to the

      generally available to the public other than by disclosure in violation of
      this
      or any other agreement, or (e) such Securityholder consents to the form and
      content of any such disclosure. The Company agrees that it shall, upon learning
      that disclosure of such information concerning any Selling
      Securityholder
      is
      sought in or by a court or governmental body of competent jurisdiction in or
      through other means, give prompt notice to such Securityholder prior to making
      such disclosure, and allow such Selling
      Securityholder,
      at its
      expense, to undertake appropriate action to prevent disclosure of, or to obtain
      a protective order for, such information.

      by the Company.
      The
      Company will indemnify, hold harmless and defend (a) the Selling
      Securityholders, (b) each
      underwriter of Registrable Securities and (c) the
      directors, officers, partners, members, employees, agents and persons who

      persons named in clauses (a), (b) and (c) being a “Company Indemnified Person”),
      against any losses, claims, damages, liabilities or expenses (collectively,
      together with actions, proceedings or inquiries whether or not in any court,
      before any administrative body or by any regulatory or self-regulatory
      organization, whether commenced or threatened, in respect thereof, “Claims”) to
      which any of them may become subject insofar as such Claims arise out of or
      are
      based upon: (i) any untrue statement or alleged untrue statement of a
      material fact contained in a Registration Statement or the omission or alleged
      omission to state therein a material fact required to be stated or necessary
      to
      make the statements therein not misleading, (ii) any untrue statement or
      alleged untrue statement of a material fact contained in any preliminary
      prospectus if used prior to the effective date of such Registration Statement,
      or contained in the final prospectus (as amended or supplemented, if the Company
      files any amendment thereof or supplement thereto with the SEC) or the omission
      or alleged omission to state therein any material fact necessary to make the
      statements made therein, in light of the circumstances under which the
      statements therein were made, not misleading, or (iii) any violation or
      alleged violation by the Company of the Securities Act, the Exchange Act, any
      other law, including, without limitation, any state securities law, or any
      rule
      or regulation thereunder relating to the offer or sale of the Registrable
      Securities (the matters in the foregoing clauses (i) through (iii) being,
      collectively, “Violations”). The Company shall reimburse each Company
      Indemnified Person, as such expenses are incurred and are due and payable,
      for
      any reasonable legal fees and other reasonable expenses incurred by them in
      connection with investigating or defending any such Claim within twenty (20)
      Business Days of written notice thereof; provided that each Company Indemnified
      Person shall promptly reimburse the Company within two (2) Business Days for
      that portion of such fees and expenses applicable to such actions for which
      such
      Indemnified Person is judicially determined to be not entitled to
      indemnification hereunder. Notwithstanding anything to the contrary contained
      herein, the Company shall not be required to indemnify or hold harmless a
      Company Indemnified Person (A) with respect to a Claim arising out of or based
      upon (1) any violation of federal or state securities laws, rules or regulations
      committed by such Company Indemnified Person (or any person who controls it
      or
      any agent, broker-dealer or underwriter engaged by it) or in the case of a
      non-underwritten offering, any failure by such Company Indemnified Person to
      give any purchaser of Registrable Securities at or prior to the written
      confirmation of such sale, a copy of the most recent prospectus, (2) an untrue
      or alleged untrue statement or omission or alleged omission contained in any
      Registration Statement or prospectus which statement or omission was made in
      reliance upon and in conformity with written information provided by or on
      behalf of such Company Indemnified Person specifically for use or inclusion
      in
      the Registration Statement or any prospectus, (3) any prospectus used after
      such
      time as the Company advised such Company Indemnified Person that the filing
      of a
      post-effective amendment or supplement thereto was required, except the
      prospectus as so amended or supplemented, or (4) any prospectus used after
      such
      time as the Company’s obligation to keep the Registration Statement effective
      and current has expired or been suspended hereunder, provided, that the Company
      has so advised such Company Indemnified Person; (B) shall not apply to amounts
      paid in settlement of any Claim if such settlement is effected without the
      prior
      written consent of the Company, which consent shall not be unreasonably
      withheld; and (C) with respect to any preliminary prospectus, shall not inure
      to
      the benefit of a Company Indemnified Person if the untrue or alleged untrue
      statement or omission or alleged omission of material fact contained in the
      preliminary prospectus was corrected on a timely basis in the prospectus, as
      then amended or supplemented, if such corrected prospectus was timely made
      available by the Company pursuant to Section 3.6 hereof, and such Company
      Indemnified Person was promptly advised in writing not to use the incorrect
      prospectus prior to the use giving rise to a Claim and such Company Indemnified
      Person, notwithstanding such advice, used it. Such indemnity shall remain in
      full force and effect regardless of any investigation made by or on behalf
      of
      the Company Indemnified Person and shall survive the transfer of the Registrable
      Securities by any of the Securityholders pursuant to Article 10.

    6.2 Indemnification
      by Selling Securityholders. The Selling Securityholders shall indemnify, hold
      harmless and defend,
      to the same extent and in the same manner set forth in Section 6.1, the Company,
      each of its directors, each of its officers who signs the Registration
      Statement, its employees, agents and persons, if any, who control the Company
      within the meaning of Section 15 of the Securities Act or Section 20 of the
      Exchange Act, any other person selling securities pursuant to the Registration
      Statement, any underwriter of securities covered by such Registration Statement,
      together with its directors, officers and members, and any person who controls
      such other person selling securities or underwriter within the meaning of the
      Securities Act or the Exchange Act (each, a “Securityholder Indemnified Person”
and collectively with a Company Indemnified Person, an “Indemnified Person”),
      against any Claim to which any of them may become subject, under the Securities
      Act, the Exchange Act or otherwise, insofar as such Claim arises out of or
      is
      based upon any Violation, in each case to the extent (and only to the extent)
      that such Violation occurs in reliance upon and in conformity with written
      information furnished to the Company by such Selling
      Securityholders expressly
      for use in connection with such Registration Statement; and such Selling
      Securityholders will
      reimburse any reasonable legal or other reasonable expenses ( within
      twenty (20) Business Days of written notice thereof; provided that each Company
      Indemnified Person shall promptly reimburse the Company within two (2) Business
      Days for that portion of such fees and expenses applicable to such actions
      for
      which such Indemnified Person is judicially determined to be not entitled to
      indemnification hereunder
      as such
      expenses are incurred and are due and payable) incurred by the Company in
      connection with investigating or defending any such Claim; provided,
      however,
      that
      the indemnity agreement contained in this Section 6.2 shall not apply to amounts
      paid in settlement of any Claim if such settlement is effected without the
      prior
      written consent of such Selling
      Securityholders,
      which
      consent shall not be unreasonably withheld. A Selling
      Securityholder
      shall be
      liable under this Agreement (including this Section 6.2 and Article 7) for
      only
      that amount as does not exceed the net proceeds actually received by such
Selling
      Securityholder
      as a
      result of the sale of Registrable Securities pursuant to such Registration
      Statement. Such indemnity shall remain in full force and effect regardless
      of
      any investigation made by or on behalf of such Securityholder
      Indemnified Person and shall survive the transfer of the Registrable Securities
      by any of the Securityholders pursuant to Article 10. Notwithstanding anything
      to the contrary contained herein, the indemnification agreement contained in
      this Section 6.2 with respect to any preliminary prospectus shall not inure
      to
      the benefit of any Securityholder
      Indemnified Person if the untrue or alleged untrue statement or omission or
      alleged omission of material fact contained in the preliminary prospectus was
      corrected on a timely basis in the prospectus, as then amended or supplemented,
      and the Securityholder
      Indemnified Person failed to utilize such corrected prospectus.

     

    6.3 Notices.
      Promptly after receipt by an Indemnified Person under
      this Article 6 of notice of the commencement of any action (including, without
      limitation, any governmental action), such Indemnified Person shall, if a Claim
      in respect thereof is to be made against any indemnifying party under this
      Article 6, deliver to the indemnifying party a written notice of the
      commencement thereof, and the indemnifying party shall have the right (at its
      expense) to participate in, and, to the extent the indemnifying party so
      desires, jointly with any other indemnifying party similarly noticed, to assume
      and continue control of the defense thereof with counsel mutually satisfactory
      to the indemnifying party and the Indemnified Person, as the case may be;
provided,
      however,
      that
      such indemnifying party shall diligently pursue such defense and an indemnifying
      party shall not be entitled to assume (or continue) such defense if the
      representation by such counsel of the Indemnified Person and the indemnifying
      party would be inappropriate due to actual or potential conflicts of interest
      between such Indemnified Person and any other party represented by such counsel
      in such proceeding or the actual or potential defendants in, or targets of,
      any
      such action include both the Indemnified Person and the indemnifying party,
      and
      any such Indemnified Person reasonably determines that there may be legal
      defenses available to such Indemnified Person which are different from or in
      addition to those available to such indemnifying party. Notwithstanding any
      assumption of such defense and without limiting any indemnification obligation
      provided for in Section 6.1 or 6.2, the Indemnified Person shall be entitled
      to
      be represented by counsel (at its own expense if the indemnifying party is
      permitted to assume and continue control of the defense and otherwise at the
      expense of the indemnifying party) and such counsel shall be entitled to
      participate in such defense. The failure to deliver written notice to the
      indemnifying party within a reasonable time of the commencement of any such
      action shall not relieve such indemnifying party of any liability to the
      Indemnified Person under this Article 6, except to the extent that the
      indemnifying party is actually materially prejudiced in its ability to defend
      such action.

    ARTICLE
      7 - CONTRIBUTION

     

    7.1 Contribution.
      To
      provide for just and equitable contribution, if (i) an indemnified party makes
      a
      claim for indemnification pursuant to Section 6.1 or 6.2 (subject to the
      limitations thereof) but it is found in a final judicial determination, not
      subject to further appeal, that such indemnification may not be enforced in
      such
      case, even though this Agreement expressly provides for indemnification in
      such
      case, or (ii) any indemnified or indemnifying party seeks contribution under
      the
      Securities Act, the Exchange Act or otherwise, then the Company (including
      for
      this purpose any contribution made by or on behalf of any director of the
      Company, any officer of the Company who signed any such Registration Statement,
      and any controlling person of the Company within the meaning of Section 15
      of
      the Securities Act or Section 20(a) of the Exchange Act), as one entity, and
      the
      Selling Securityholders whose Registrable Securities are included in such
      registration in the aggregate (including for this pur-pose any contribution
      by
      or on behalf of an indemnified party), as a second entity, shall contribute
      to
      the losses, liabilities, claims, damages, and expenses whatsoever to which
      any
      of them may be subject, on the basis of relevant equitable considerations such
      as the relative fault of the Company and such Selling Securityholders in
      connection with the facts which resulted in such losses, liabilities, claims,
      damages, and expenses. The relative fault, in the case of an untrue statement,
      alleged untrue statement, omission, or alleged omission, shall be
      determined,
      among
      other things, by whether such statement, alleged statement, omission, or alleged
      omis-sion relates to information supplied by the Company or by such Selling
      Securityholders, and the parties’ relative intent, knowledge, access to
      information, and opportunity to correct or prevent such statement, alleged
      statement, omission, or alleged omission. Subject to the following sentence,
      the
      Company and the Selling
      Securityholders agree
      that it would be unjust and inequitable if the respective obligations of the
      Company and the Selling Securityholders for contribution were determined by
      pro
      rata or per capita allocation of the aggregate losses, liabilities, claims,
      damages, and expenses (even if the Selling Securityholders and the other
      indemnified parties were treated as one entity for such purpose) or by any
      other
      method of allocation that does not reflect the equitable considerations referred
      to in this Section 7.1. In no case shall any Selling Securityholder be
      responsible for a portion of the contribution obligation imposed on all Selling
      Securityholders in excess of the net proceeds actually received by such Selling
      Securityholder as a result of the sale of Registrable Securities pursuant to
      such Registration Statement. No person guilty of a fraudulent misrepresentation
      (within the meaning of Section 11(f) of the Securities Act) shall be entitled
      to
      contribution from any person who is not guilty of such fraudulent
      misrepresentation. For purposes of this Section 7.1, each person, if any, who
      controls any Selling Securityholder within the meaning of Section 15 of the
      Securities Act or Section 20(a) of the Exchange Act and each officer, director,
      partner, employee, agent, and counsel of each such Selling Securityholder or
      control person shall have the same rights to contribution as such Selling
      Securityholder or control person and each person, if any, who controls the
      Company within the meaning of Section 15 of the Securities Act or Section 20(a)
      of the Exchange Act, each officer of the Company who signs the Registration
      Statement, each director of the Company, and its or their respective counsel
      shall have the same rights to contribution as the Company, subject in each
      case
      to the provisions of this Section 7.1. Anything in this Section 7.1 to the
      contrary notwithstanding, no party shall be liable for contribution with respect
      to the settlement of any claim or action effected without its written consent.
      This Section 7.1 is intended to supersede any right to contribution under the
      Securities Act, the Exchange Act or otherwise.

    10.3
      Delays or Omissions.
      Except
      as expressly provided in this Agreement, no delay or omission to exercise any
      right, power or remedy accruing to any Securityholder upon any breach or default
      of the Company under this Agreement shall impair any such right, power or remedy
      of such Securityholder nor shall it be construed to be a waiver of any such
      breach or default, or an acquiescence therein, or of or in any similar breach
      or
      default thereafter occurring; nor shall any waiver of any single breach or
      default be deemed a waiver of any other breach or default theretofore or
      thereafter occurring. Any waiver, permit, consent or approval of any kind or
      character on the part of any Securityholder of any breach or default under
      this
      Agreement, or any waiver on the part of any Securityholder of any provisions
      or
      conditions of this Agreement, must be in writing and shall be effective only
      to
      the extent specifically set forth in such writing. All remedies, either under
      this Agreement or by law or otherwise afforded to any Securityholder shall
      be
      cumulative and not alternative.

    10.5 Entire
      Agreement; Amendment.
      This
      Agreement constitutes the full and entire understanding and agreement between

      or
      termination is sought.

     

    10.6 Successors

      of, and be binding upon, the permitted successors, assigns, heirs, executors
      and

      not
      assign this Agreement without the written consent of the holders of at least
      50%
      of the then outstanding Registrable Securities; provided
      that,
      the
      Company shall not agree to or consummate any Exchange in
      which
      the Registrable Securities are to be exchanged, converted into or otherwise
      become the securities of any other issuer, without procuring that such issuer
      assume the liabilities of the Company hereunder, effective upon the consummation
      of such Exchange on terms that are fair to the Securityholders.

    10.7 Titles
      and Subtitles.
      The
      headings in this Agreement are used for convenience of reference only and shall
      not be considered in construing or interpreting this Agreement.

      by facsimile, and facsimile signatures shall be treated as original signatures
      for all applicable purposes.

     

    10.9 
      Further Assurances.
      Each
      party shall do and perform, or cause to be done and performed, all such further
      acts and things, and shall execute and deliver all such other agreements,
      certificates, instruments and documents, as the other party may reasonably
      request in order to carry out the intent and accomplish the purposes of this
      Agreement and the consummation of the transactions contemplated
      hereby.

     

    10.10 
      Consents.
      Unless
      otherwise provided herein, all consents and other determinations to be made
      pursuant to this Agreement shall be made on the basis of a majority in interest
      (determined by number of securities) with respect to the Registrable
      Securities.

     

    10.11 Severability.
      In the
      event that any provision of this Agreement becomes or is declared by a court

      competent jurisdiction to be illegal, unenforceable or void, this Agreement
      shall continue in full force and effect without said provision.

     

    10.12 No
      Third Party Beneficiaries.
      This
      Agreement shall not confer any rights or remedies upon any person other than
      the
      parties hereto, each Securityholder, their permitted successors and assigns
      and
      parties eligible for indemnification under Article 6, and only in accordance
      with the express terms of this Agreement.

     

    10.13 Confidentiality
      of Agreement, Press Releases and Public Announcements.
      Except
      as set forth below, the parties shall, and shall cause their officers, employees
      and representatives to, treat and hold as confidential the existence and terms
      of this Agreement at all times. No party shall issue any press release or make
      any public announcement relating to the subject matter of this Agreement without
      the prior written approval of the Company and the holders of at least 50% of
      the
      number of Registrable Securities; provided,
      however,
      that any
      party may make any public disclosure it believes in good faith is required
      by
      applicable law (including applicable securities laws) or any listing or trading
      agreement concerning its publicly-traded securities to make such disclosure
      (in
      which case the disclosing party will use its reasonable efforts to advise the
      other parties in writing prior to making the disclosure).

     

    10.14 Construction.
      The
      parties have participated jointly in the negotiation and drafting of this
      Agreement. In the event an ambiguity or question of intent or interpretation
      arises, this Agreement shall be construed as if drafted jointly by the parties
      and no presumption or burden of proof shall arise favoring or disfavoring any
      party by virtue of the authorship of any of the provisions of this Agreement.
      Any reference to any federal, state, local or foreign statute or law shall
      be
      deemed also to refer to all rules and regulations promulgated thereunder and
      any
      applicable common law, unless the context requires otherwise. The word
“including” shall mean including without limitation and is used in an
      illustrative sense rather than a limiting sense. Terms used with initial capital
      letters will have the meanings specified, applicable to singular and plural
      forms, for all purposes of this Agreement. Reference to any gender will be
      deemed to include all genders and the neutral form.

    10.15 Incorporation
      of Exhibits, Annexes and Schedules.
      The
      Exhibits, Annexes and Schedules identified in this Agreement, if any, are
      incorporated herein by reference and made a part hereof.

     

    10.16 Termination
      of Old Registration Rights Agreement.
      The Old
      Registration Rights Agreement is hereby terminated, without liability of any
      party thereto to any other party thereto.

     

    10.17 Independent
      Nature of Selling Securityholders' Obligations and Rights.
      The
      obligations of each Selling Securityholder hereunder is several and not joint
      with the obligations of any other Selling Securityholder hereunder, and no
      Selling Securityholder shall be responsible in any way for the performance
      of
      the obligations of any other Selling Securityholder hereunder. The decision
      of
      each Selling Securityholder to purchase Securities has been made independently
      of any other Selling Securityholder. Nothing contained herein or in any other
      agreement or document delivered at any closing, and no action taken by any
      Selling Securityholder pursuant hereto or thereto, shall be deemed to constitute
      the Selling Securityholders as a partnership, an association, a joint venture
      or
      any other kind of entity, or create a presumption that the Selling
      Securityholders are in any way acting in concert with respect to such
      obligations or the transactions contemplated by this Agreement. Each Selling
      Securityholder acknowledges that no other Selling Securityholder has acted
      as
      agent for such Selling Securityholder in connection with making its investment
      hereunder and that no Selling Securityholder will be acting as agent of such
      Selling Securityholder in connection with monitoring its investment in the
      Securities or enforcing its rights under this Agreement and the Warrants. Each
      Selling Securityholder shall be entitled to protect and enforce its rights,
      including without limitation the rights arising out of this Agreement, and
      it
      shall not be necessary for any other Selling Securityholder to be joined as
      an
      additional party in any proceeding for such purpose.
