        documents. The Company is duly qualified to do business and is in good standing
        as a foreign corporation in each jurisdiction in which the nature of the
        business conducted or property owned by it makes such qualification necessary,
        except where the failure to be so qualified or in good standing, as the case

        be, could not, individually or in the aggregate, (i) adversely affect the
        legality, validity or enforceability of any Transaction Document, (ii) have
        or
        result in a material adverse effect on the results of operations, assets,
        prospects, business or condition (financial or otherwise) of the Company,

        Company has the requisite corporate power and authority to enter into and
        to
        consummate the transactions contemplated by each of the Transaction Documents
        and otherwise to carry out its obligations hereunder and thereunder. The
        execution and delivery of each of the Transaction Documents by the Company
        and
        the consummation by it of the transactions contemplated hereby and thereby
        have
        been duly authorized by all necessary action on the part of the Company and
        no
        further consent or action is required by the Company, its Board of Directors
        or
        its shareholders. Each of the Transaction Documents has been (or upon delivery
        will be) duly executed by the Company and is, or when delivered in accordance
        with the terms hereof, will constitute, the valid and binding obligation
        of the
        Company enforceable against the Company in accordance with its
        terms.

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      (c)
         No
        Conflicts.
        The
        execution, delivery and performance of the Transaction Documents by the Company
        and the consummation by the Company of the transactions contemplated hereby
        and
        thereby do not and will not (i) conflict with or violate any provision of
        the
        Company’s articles of incorporation, bylaws or other organizational or charter
        documents, (ii) conflict with, or constitute a default (or an event that
        with

        others
        any rights of termination, amendment, acceleration or cancellation (with
        or
        without notice, lapse of time or both) of, any agreement, credit facility,
        debt
        or other instrument (evidencing a Company or Subsidiary debt or otherwise)

        or
        asset of the Company is bound or affected, or (iii) result in a violation
        of any

        convertible or exchangeable into shares of Common Stock. The issue and sale
        of
        the Securities (including the Underlying Shares) will not obligate the Company
        to issue shares of Common Stock or other securities to any Person (other
        than
        the Purchasers) and will not result in a right of any holder of Company
        securities to adjust any exercise, conversion, exchange or reset price under
        such securities. 

       

      (f)
         SEC
        Reports; Financial Statements.
        The
        Company has filed all reports required to be filed by it under the Exchange
        Act,
        including pursuant to Section 13(a) or 15(d) thereof, for at least the 12
        months
        preceding the date hereof (or such shorter period as the Company was required
        by
        law to file such material) (the foregoing materials (together with any materials
        filed by the Company under the Exchange Act, whether or not required) being
        collectively referred to herein as the “SEC
        Reports”
        and,
        together with this Agreement and the Schedules to this Agreement, the
“Disclosure
        Materials”)
        on a
        timely basis or has received a valid extension of such time of filing and
        has
        filed any such SEC Reports prior to the expiration of any such extension.
        As of
        their respective dates, the SEC Reports complied in all material respects
        with
        the requirements of the Securities Act and the Exchange Act and the rules
        and
        regulations of the Commission promulgated thereunder, and none of the SEC
        Reports, when filed, contained any untrue statement of a material fact or
        omitted to state a material fact required to be stated therein or necessary
        in
        order to make the statements therein, in the light of the circumstances under
        which they were made, not misleading. The financial statements of the Company
        included in the SEC Reports comply in all material respects with applicable
        accounting requirements and the rules and regulations of the Commission with
        respect thereto as in effect at the time of filing. Such financial statements
        have been prepared in accordance with United States generally accepted
        accounting principles applied on a consistent basis during the periods involved
        (“GAAP”),
        except
        as may be otherwise specified in such financial statements or the notes thereto,
        and fairly present in all material respects the financial position of the
        Company and its consolidated subsidiaries as of and for the dates thereof
        and
        the results of operations and cash flows for the periods then ended, subject,
        in
        the case of unaudited statements, to normal, immaterial, year-end audit
        adjustments. 

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      (g)
         Material
        Changes.
        Since
        the date of the latest audited financial statements included within the SEC
        Reports, except as specifically disclosed in the SEC Reports, there has been
        no
        event, occurrence or development that, individually or in the aggregate,
        has had
        or that is reasonably likely to result in a Material Adverse
        Effect.

       

      (h)
         Absence
        of Litigation.
        Except
        as disclosed in the SEC Reports, there is no action, suit, claim, proceeding,
        inquiry or investigation before or by any court, public board, government
        agency, self-regulatory organization or body pending or, to the knowledge
        of the
        Company, threatened against or affecting the Company that is reasonably likely
        to, individually or in the aggregate, have a Material Adverse Effect.

       

      (i)
         Compliance.
        The
        Company (i) is not in default under or in violation of (and no event has
        occurred that has not been waived that, with notice or lapse of time or both,
        would result in a default by the Company under), nor has the Company received
        notice of a claim that it is in default under or that it is in violation
        of, any
        indenture, loan or credit agreement or any other agreement or instrument
        to
        which it is a party or by which it or any of its properties is bound (whether
        or
        not such default or violation has been waived), (ii) is in violation of any
        order of any court, arbitrator or governmental body, or (iii) is in violation
        of
        any statute, rule or regulation of any governmental authority, including
        without
        limitation all foreign, federal, state and local laws relating to taxes,
        environmental protection, occupational health and safety, product quality
        and
        safety and employment and labor matters, except in each case as could not,
        individually or in the aggregate, have or result in a Material Adverse Effect.
        

       

      (j)
         Title
        to Assets.
        The
        Company has good and marketable title in fee simple to all real property
        owned
        by it that is material to the business of the Company and good and marketable
        title in all personal property owned by it that is material to the business
        of
        the Company, in each case free and clear of all Liens, except for Liens as
        do
        not materially affect the value of such property and do not materially interfere
        with the use made and proposed to be made of such property by the Company.
        Any
        real property and facilities held under lease by the Company is held by it
        under
        valid, subsisting and enforceable leases of which the Company is in compliance
        except such non-compliance as would not have a Material Adverse
        Effect.

       

      (k)
         Listing
        and Maintenance Requirements.
        The
        Company has not, in the two years preceding the date hereof, received notice
        (written or oral) from any Trading Market on which the Common Stock is or
        has
        been listed or quoted to the effect that the Company is not in compliance
        with
        the listing or maintenance requirements of such Trading Market. The Company
        is,
        and has no reason to believe that it will not in the foreseeable future continue
        to be, in compliance with all such listing and maintenance requirements.
        

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      (l)
         Acknowledgment
        Regarding Purchasers' Purchase of Securities.
        The
        Company acknowledges and agrees that each of the Purchasers is acting solely
        in
        the capacity of an arm's length purchaser with respect to this Agreement
        and the
        transactions contemplated hereby. The Company further acknowledges that no
        Purchaser is acting as a financial advisor or fiduciary of the Company (or
        in
        any similar capacity) with respect to this Agreement and the transactions
        contemplated hereby and any advice given by any Purchaser or any of their
        respective representatives or agents in connection with this Agreement and
        the
        transactions contemplated hereby is merely incidental to the Purchasers'
        purchase of the Securities. The Company further represents to each Purchaser
        that the Company's decision to enter into this Agreement has been based solely
        on the independent evaluation of the transactions contemplated hereby by
        the
        Company and its representatives.

       

      (m)
         Patents
        and Trademarks.
        The
        Company has valid title to all patents, patent applications, trademarks,
        trademark applications, service marks, trade names, copyrights, licenses
        and
        other similar rights that are necessary or material for use in connection
        with
        its business as described in the SEC Reports and which the failure to so
        have
        could have a Material Adverse Effect (collectively, the "Intellectual
        Property Rights").
        To
        the knowledge of the Company, all such Intellectual Property Rights are
        enforceable and there is no existing infringement by another Person of any
        of
        the Intellectual Property Rights.

       

      (n)
         Insurance.
        The
        Company is insured by insurers of recognized financial responsibility against
        such losses and risks and in such amounts as are prudent and customary in
        the
        businesses in which the Company is engaged. 

       

      (o)
         Regulatory
        Permits.
        The
        Company possesses all certificates, authorizations and permits issued by
        the
        appropriate federal, state, local or foreign regulatory authorities necessary
        to
        conduct their respective businesses as described in the SEC Reports, except
        where the failure to possess such permits could not, individually or in the
        aggregate, have or result in a Material Adverse Effect (“Material
        Permits”).

       

      (p)
         Solvency.
        Based
        on the financial condition of the Company as of the Closing Date, (i) the
        Company’s fair saleable value of its assets exceeds the amount that will be
        required to be paid on or in respect of the Company’s existing debts and other
        liabilities (including known contingent liabilities) as they mature; (ii)
        the
        Company’s assets do not constitute unreasonably small capital to carry on its
        business for the current fiscal year as now conducted and as proposed to
        be
        conducted including its capital needs taking into account the particular
        capital
        requirements of the business conducted by the Company, and projected capital
        requirements and capital availability thereof; and (iii) the current cash
        flow
        of the Company, together with the proceeds the Company would receive, were
        it to
        liquidate all of its assets, after taking into account all anticipated uses
        of
        the cash, would be sufficient to pay all amounts on or in respect of its
        debt
        when such amounts are required to be paid. The Company does not intend to
        incur
        debts beyond its ability to pay such debts as they mature (taking into account
        the timing and amounts of cash to be payable on or in respect of its
        debt).

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      (q)
         Going
        Concern.
        The
        Company has no knowledge (upon receipt of the proceeds of this transaction)
        that
        the Company’s independent public accountants will issue an audit letter
        containing a “going concern” opinion or other qualification in connection with
        the Company’s annual report on Form 10-KSB pursuant to Section 13 or 15(d) under
        the Exchange Act for the fiscal year ended December 31, 2005.

       

      (r)
         Internal
        Accounting Controls.
        The
        Company maintains a system of internal accounting controls sufficient to
        provide
        reasonable assurance that (i) transactions are executed in accordance with
        management’s general or specific authorizations, (ii) transactions are recorded
        as necessary to permit preparation of financial statements in conformity
        with
        generally accepted accounting principles and to maintain asset accountability,
        (iii) access to assets is permitted only in accordance with management’s general
        or specific authorization, and (iv) the recorded accountability for assets
        is
        compared with the existing assets at reasonable intervals and appropriate
        action
        is taken with respect to any differences.

       

      (s)
         Sarbanes-Oxley
        Act.
        The
        Company is in compliance with applicable requirements of the Sarbanes-Oxley
        Act
        of 2002 and applicable rules and regulations promulgated by the Commission
        thereunder in effect as of the date of this Agreement, except where such
        noncompliance could not be reasonably expected to have, individually or in
        the aggregate, a Material Adverse Effect.

       

      3.2
         Representations
        and Warranties of the Purchasers.
        Each
        Purchaser hereby, as to itself only and for no other Purchaser, represents
        and
        warrants to the Company as follows:

       

      (a)
         Organization;
        Authority.
        Such
        Purchaser is an entity duly organized, validly existing and in good standing
        under the laws of the jurisdiction of its organization with the requisite
        corporate or partnership power and authority to enter into and to consummate
        the
        transactions contemplated by the Transaction Documents and otherwise to carry
        out its obligations thereunder. The purchase by such Purchaser of the Shares
        hereunder has been duly authorized by all necessary action on the part of
        such
        Purchaser. This Agreement has been duly executed and delivered by such Purchaser
        and constitutes the valid and binding obligation of such Purchaser, enforceable
        against it in accordance with its terms.

       

      (b)
         Investment
        Intent.
        Such
        Purchaser is acquiring the Securities for investment purposes only and not
        with
        a view to or for distributing or reselling such Securities or any part thereof,
        without prejudice, however, to such Purchaser's right, subject to the provisions
        of this Agreement, at all times to sell or otherwise dispose of all or any
        part
        of such Securities pursuant to an effective registration statement under
        the
        Securities Act or under an exemption from such registration and in compliance
        with applicable federal and state securities laws. Nothing contained herein
        shall be deemed a representation or warranty by such Purchaser to hold
        Securities for any period of time. 

       

      (c)
         Purchaser
        Status.
        At the
        time such Purchaser was offered the Shares and the Warrants, it was, and
        at the
        date hereof it is, an “accredited investor” as defined in Rule 501(a) under the
        Securities Act. If such Purchaser was formed specifically for the purpose
        of
        investing in the Shares and the Warrants, each of its beneficial owners is
        an
“accredited investor” as defined in Rule 501(a) of the Securities
        Act.

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      (d)
         Experience
        of such Purchaser.
        Such
        Purchaser, either alone or together with its representatives, has such
        knowledge, sophistication and experience in business and financial matters
        so as
        to be capable of evaluating the merits and risks of the prospective investment
        in the Securities, and has so evaluated the merits and risks of such investment.
        Such Purchaser is able to bear the economic risk of an investment in the
        Securities and, at the present time, is able to afford a complete loss of
        such
        investment.

       

      (e)
         Access
        to Information.
        Such
        Purchaser has had the opportunity to ask questions or, and receive answers
        from,
        representatives of the Company concerning the Company and the terms and
        conditions of this transaction, as well as obtain any information requested
        by
        such Purchaser. Such Purchaser's decision to enter into the transactions
        contemplated hereby is based on such Purchaser's own evaluation of the risks
        and
        merits of an investment in Company. Such Purchaser acknowledges that such
        Purchaser’s investment in the Securities involves a high degree of
        risk.

      

      

      ARTICLE
        IV

      OTHER
        AGREEMENTS OF THE PARTIES

       

      4.1
         Transfer
        Restrictions.

       

      (a)
         Securities
        may only be disposed of pursuant to an effective registration statement under
        the Securities Act or pursuant to an available exemption from the registration
        requirements of the Securities Act, and in compliance with any applicable
        state
        securities laws. In connection with any transfer of Securities other than
        pursuant to an effective registration statement or to the Company or pursuant
        to
        Rule 144(k), except as otherwise set forth herein, the Company may require
        the
        transferor to provide to the Company an opinion of counsel selected by the
        transferor, the form and substance of which opinion shall be reasonably
        satisfactory to the Company, to the effect that such transfer does not require
        registration under the Securities Act. Notwithstanding the foregoing, the
        Company hereby consents to and agrees to register on the books of the Company
        and with its transfer agent, without any such legal opinion, any transfer
        of
        Securities by a Purchaser to an Affiliate of such Purchaser, provided that
        the
        transferee certifies to the Company that it is an “accredited investor” as
        defined in Rule 501(a) under the Securities Act.

       

      (b)
         The
        Purchasers agree to the imprinting, so long as is required by this Section
        4.1(b),
        of the
        following legend on any certificate evidencing Securities: 

       

      NEITHER
        THESE SECURITIES NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE EXERCISABLE
        HAVE BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE
        SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM
        REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
        ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN
        EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO
        AN
        AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
        REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE
        SECURITIES LAWS OR BLUE SKY LAWS. 

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      (c)
         Certificates
        evidencing Securities shall not be required to contain such legend or any
        other
        legend (i) while a Registration Statement covering the resale of such Securities
        is effective under the Securities Act, or (ii) following any sale of such
        Securities pursuant to Rule 144, or (iii) if such Securities are eligible
        for
        sale under Rule 144(k), or (iv) if such legend is not required under applicable
        requirements of the Securities Act (including judicial interpretations and
        pronouncements issued by the Staff of the Commission). Following the Effective
        Date or at such earlier time as a legend is no longer required for certain
        Securities, the Company will no later than three Trading Days following the
        delivery by a Purchaser to the Company or the Company’s transfer agent of a
        legended certificate representing such Securities, deliver or cause to be
        delivered to such Purchaser a certificate representing such Securities that
        is
        free from all restrictive and other legends. The Company may not make any
        notation on its records or give instructions to any transfer agent of the
        Company that enlarge the restrictions on transfer set forth in this
        Section.

       

      4.2
         Furnishing
        of Information.
        As long
        as any Purchaser owns Securities, the Company covenants to timely file (or
        obtain extensions in respect thereof and file within the applicable grace
        period) all reports required to be filed by the Company after the date hereof
        pursuant to the Exchange Act. Upon the request of any Purchaser, the Company
        shall deliver to such Purchaser a written certification of a duly authorized
        officer as to whether it has complied with the preceding sentence. As long
        as
        any Purchaser owns Securities, if the Company is not required to file reports
        pursuant to such laws, it will prepare and furnish to the Purchasers and
        make
        publicly available in accordance with paragraph (c) of Rule 144 such information
        as is required for the Purchasers to sell the Securities under Rule 144.
        The
        Company further covenants that it will take such further action as any holder
        of
        Securities may reasonably request to satisfy the provisions of Rule 144
        applicable to the issuer of securities relating to transactions for the sale
        of
        securities pursuant to Rule 144.

       

      4.3
         Reservation
        and Listing of Securities.
        The
        Company shall maintain a reserve from its duly authorized shares of Common
        Stock
        for issuance pursuant to the Transaction Documents in such amount as may
        be
        required to fulfill its obligations in full under the Transaction Documents.
        In
        the event that at any time the then authorized shares of Common Stock are
        insufficient for the Company to satisfy its obligations in full under the
        Transaction Documents, the Company shall promptly take such actions as may
        be
        required to increase the number of authorized shares. The Company shall in
        the
        time and manner required by its Trading Market, prepare and file with such
        Trading Market an additional shares listing application covering the number
        of
        shares of Common Stock issuable under the Transaction Documents and shall
        take
        all steps necessary to cause such shares of Common Stock to be approved for
        listing on its Trading Market as soon as possible.

         Reimbursement.
        If any
        Purchaser or any of its Affiliates or any officer, director, partner,
        controlling Person, employee or agent of a Purchaser or any of its Affiliates
        (a
“Related
        Person”)
        becomes involved in any capacity in any Proceeding brought by or against
        any
        Person in connection with or as a result of the transactions contemplated
        by the
        Transaction Documents, the Company will indemnify and hold harmless such
        Purchaser or Related Person for its reasonable legal and other expenses
        (including the costs of any investigation, preparation and travel) and for
        any
        Losses incurred in connection therewith, as such expenses or Losses are
        incurred, excluding only Losses that result directly from such Purchaser’s or
        Related Person’s gross negligence or willful misconduct. In addition, the
        Company shall indemnify and hold harmless each Purchaser and Related Person
        from
        and against any and all Losses, as incurred, arising out of or relating to
        any
        breach by the Company of any of the representations, warranties or covenants
        made by the Company in this Agreement or any other Transaction Document,
        or any
        allegation by a third party that, if true, would constitute such a breach.
        The
        conduct of any Proceedings for which indemnification is available under this
        paragraph shall be governed by Section 6.4(c) below. The indemnification
        obligations of the Company under this paragraph shall be in addition to any
        liability that the Company may otherwise have and shall be binding upon and
        inure to the benefit of any successors, assigns, heirs and personal
        representatives of the Purchasers and any such Related Persons. The Company
        also
        agrees that neither the Purchasers nor any Related Persons shall have any
        liability to the Company or any Person asserting claims on behalf of or in
        right
        of the Company in connection with or as a result of the transactions
        contemplated by the Transaction Documents, except to the extent that any
        Losses
        incurred by the Company result from the gross negligence or willful misconduct
        of the applicable Purchaser or Related Person in connection with such
        transactions.
        If
        the
        Company breaches its obligations under any Transaction Document, then, in
        addition to any other liabilities the Company may have under any Transaction
        Document or applicable law, the Company shall pay or reimburse the Purchasers
        on
        demand for all costs of collection and enforcement (including reasonable
        attorneys fees and expenses). Without limiting the generality of the foregoing,
        the Company specifically agrees to reimburse the Purchasers on demand for
        all
        costs of enforcing the indemnification obligations in this
        paragraph.

        Registration

       

      (a)
         As
        promptly as possible, and in any event on or prior to the Filing Date, the
        Company shall prepare and file with the Commission a “Shelf” Registration
        Statement covering the resale of all Registrable Securities for an offering
        to
        be made on a continuous basis pursuant to Rule 415. The Registration Statement
        shall be on Form S-3 (except if the Company is not then eligible to register
        for
        resale the Registrable Securities on Form S-3, in which case such registration
        shall be on Form S-1 or another appropriate form in accordance herewith as
        the
        Purchasers may consent).

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      (b)
         The
        Company shall use its best efforts to cause the Registration Statement to
        be
        declared effective by the Commission as promptly as possible after the filing
        thereof, but in any event prior to the Required Effectiveness Date, and shall
        use its best efforts to keep the Registration Statement continuously effective
        under the Securities Act until the fifth anniversary of the Effective Date
        or
        such earlier date when all Registrable Securities covered by such Registration
        Statement have been sold publicly or are freely tradeable under U.S. securities
        laws (the “Effectiveness
        Period”).

       

      (c)
         The
        Company shall notify each Purchaser in writing promptly (and in any event
        within
        one Trading Day) after receiving notification from the Commission that the
        Registration Statement has been declared effective. 

       

      (d)
         As
        promptly as possible, and in any event no later than the Post-Effective
        Amendment Filing Deadline, the Company shall prepare and file with the
        Commission a Post-Effective Amendment. The Company shall use its best efforts
        to
        cause the Post-Effective Amendment to be declared effective by the Commission
        as
        promptly as possible after the filing thereof, but in any event prior to
        the
        fifteenth Trading Day after the Post-Effective Amendment Filing Deadline.
        The
        Company shall notify each Purchaser in writing promptly (and in any event
        within
        one business day) after receiving notification from the Commission that the
        Post-Effective Amendment has been declared effective.

       

      (e)
         If:
        (i)
        any Registration Statement is not declared effective by the Commission by
        the
        Required Effectiveness Date or (ii) a Post-Effective Amendment is not declared
        effective on or prior to the fifteenth Trading Day after the Post-Effective
        Amendment Filing Deadline; the date on which any such Event occurs being
        referred to as “Event
        Date”),
        then
        on each monthly anniversary of each such Event Date thereof (if the applicable
        Event shall not have been cured by such date) until the applicable Event
        is
        cured, the Company shall pay to each Purchaser an amount in cash, as partial
        liquidated damages and not as a penalty, equal to 1.5% of the aggregate purchase
        price paid by such Purchaser pursuant to the Purchase Agreement. Such payments
        shall be in partial compensation to the Purchasers and shall not constitute
        the
        Purchaser’s exclusive remedy for such events. Notwithstanding the foregoing, no
        amounts shall be payable to a Purchaser under clause (i) or (ii) above if
        the
        Registrable Securities may be sold by such Purchaser without restrictions
        under
        applicable U.S. securities laws. If the Company fails to pay any liquidated
        damages pursuant to this Section in full within seven days after the date
        payable, the Company will pay interest thereon at a rate of 18% per annum
        (or
        such lesser maximum amount that is permitted to be paid by applicable law)
        to
        the Purchaser, accruing daily from the date such liquidated damages are due
        until such amounts, plus all such interest thereon, are paid in
        cash.

       

      (f)
         Notwithstanding
        the provisions of Section 6.1(e), the Company may, during the period a
        registration statement is required to remain effective hereunder, suspend
        the
        use of the prospectus for a period not to exceed sixty (60) days (whether
        or not
        consecutive) in any 12-month period if the Board of Directors of the Company
        determines in good faith that because of valid business reasons, including
        pending mergers or other business combination transactions, the planned
        acquisition or divestiture of assets, pending material corporate developments
        and similar events, it is in the best interests of the Company to suspend
        such
        use, and prior to or contemporaneously with suspending such use the Company
        provides the Purchasers of Registrable Securities with written notice of
        such
        suspension (which notice need not specify the nature of the event giving
        rise to
        such suspension), and the Purchaser shall suspend the use of the prospectus
        until its receipt of written notice. At the end of any such suspension period
        the Company shall immediately provide the Purchasers with written notice
        of the
        termination of such suspension.

        by
        reference), the Company shall (i) furnish to each Purchaser and any counsel
        designated by any Purchaser (each, a “Purchaser

        such review must be completed within three Business Days of receipt of such
        documents), and (ii) cause its officers and directors, counsel and independent
        certified public accountants to respond to such inquiries as shall be necessary,

         (i)
        Prepare and file with the Commission such amendments, including post-effective

        effective as to the applicable Registrable Securities for the Effectiveness
        Period and prepare and file with the Commission such additional Registration
        Statements in order to register for resale under the Securities Act all of
        the
        Registrable Securities; (ii) cause the related Prospectus to be amended or

        reasonably possible, and in any event within ten days, to any comments received
        from the Commission with respect to the Registration Statement or any amendment
        thereto and as promptly as reasonably possible provide the Purchasers true
        and
        complete copies of all correspondence from and to the Commission relating
        to the
        Registration Statement; and (iv) comply in all material respects with the
        provisions of the Securities Act and the Exchange Act with respect to the
        disposition of all Registrable Securities covered by the Registration Statement
        during the applicable period in accordance with the intended methods of
        disposition by the Purchasers thereof set forth in the Registration Statement
        as
        so amended or in such Prospectus as so supplemented

       

      (c)
         Notify
        the Purchasers of Registrable Securities to be sold and Purchaser Counsel
        as
        promptly as reasonably possible, and (if requested by any such Person) confirm
        such notice in writing no later than one Trading Day thereafter, of any of
        the
        following events: (i) the Commission notifies the Company whether there will
        be
        a “review” of any Registration Statement; (ii) the Commission comments in
        writing on any Registration Statement (in which case the Company shall deliver

        (iii) any Registration Statement or any post-effective amendment is declared
        effective; (iv) the Commission or any other Federal or state governmental

        required to be stated therein or necessary to make the statements therein,
        in
        the light of the circumstances under which they were made, not
        misleading.

        to each Purchaser and Purchaser Counsel, without charge, at least one conformed
        copy of each Registration Statement and each amendment thereto, including

        copies
        of the Prospectus or Prospectuses (including each form of prospectus) and

        offering and sale of the Registrable Securities covered by such Prospectus
        and

        Securities to be approved for listing on each Trading Market as soon as possible
        thereafter; (iii) provide to the Purchasers evidence of such listing; and
        (iv)
        maintain the listing of such Registrable Securities on each such Trading
        Market
        or another Eligible Market.

       

      (h)
         Prior
        to
        any public offering of Registrable Securities, use its best efforts to register
        or qualify or cooperate with the selling Purchasers and each applicable
        Purchaser Counsel in connection with the registration or qualification (or
        exemption from such registration or qualification) of such Registrable
        Securities for offer and sale under the securities or Blue Sky laws of such
        jurisdictions within the United States as any Purchaser requests in writing,
        to
        keep each such registration or qualification (or exemption therefrom) effective
        during the Effectiveness Period and to do any and all other acts or things
        necessary or advisable to enable the disposition in such jurisdictions of
        the
        Registrable Securities covered by a Registration Statement.

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      (i)
         Cooperate
        with the Purchasers to facilitate the timely preparation and delivery of
        certificates representing Registrable Securities to be delivered to a transferee
        pursuant to a Registration Statement, which certificates shall be free, to
        the
        extent permitted by this Agreement, of all restrictive legends, and to enable
        such Registrable Securities to be in such denominations and registered in
        such
        names as any such Purchasers may request.

       

      (j)
         Upon
        the
        occurrence of any event described in Section 6.2(c)(vii), as promptly as
        reasonably possible, prepare a supplement or amendment, including a
        post-effective amendment, to the Registration Statement or a supplement to
        the
        related Prospectus or any document incorporated or deemed to be incorporated
        therein by reference, and file any other required document so that, as
        thereafter delivered, neither the Registration Statement nor such Prospectus
        will contain an untrue statement of a material fact or omit to state a material
        fact required to be stated therein or necessary to make the statements therein,
        in the light of the circumstances under which they were made, not
        misleading.

       

      (k)
         Cooperate
        with any due diligence investigation undertaken by the Purchasers in connection
        with the sale of Registrable Securities, including, without limitation, by
        making available any documents and information; provided that the Company
        will
        not deliver or make available to any Purchaser material, nonpublic information
        unless such Purchaser specifically requests in advance to receive material,
        nonpublic information in writing.

       

      (l)
         If
        Holders of a majority of the Registrable Securities being offered pursuant
        to a
        Registration Statement select underwriters for the offering, the Company
        shall
        enter into and perform its obligations under an underwriting agreement, in
        usual
        and customary form, including, without limitation, by providing customary
        legal
        opinions, comfort letters and indemnification and contribution
        obligations.

       

      (m)
         Comply
        with all applicable rules and regulations of the Commission.

       

      In
        connection with the registration of the Registrable Securities, it shall
        be a
        condition precedent to the obligations of the Company to complete the
        registration pursuant to this Agreement with respect to the Registrable
        Securities of a particular Purchaser (or to make any payments or other damages
        to such Purchaser pursuant to Section 6.1) that such Purchaser shall furnish
        to
        the Company such information regarding itself and the Registrable Securities
        held by it as shall reasonably be required to effect the registration of
        such
        Registrable Securities within five Trading Days of the Company's written
        request.

      

      6.3
         Registration
        Expenses.
        The
        Company shall pay (or reimburse the Purchasers for) all fees and expenses
        incident to the performance of or compliance with this Agreement by the Company,
        including without limitation (a) all registration and filing fees and expenses,
        including without limitation those related to filings with the Commission,
        any
        Trading Market and in connection with applicable state securities or Blue
        Sky
        laws, (b) printing expenses (including without limitation expenses of printing
        certificates for Registrable Securities and of printing prospectuses requested
        by the Purchasers), (c) messenger, telephone and delivery expenses, (d) fees
        and
        disbursements of counsel for the Company, (e) fees and expenses of all other
        Persons retained by the Company in connection with the consummation of the
        transactions contemplated by this Agreement, and (f) all listing fees to
        be paid
        by the Company to the Trading Market. 

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      6.4
         Indemnification

       

      (a)
         Indemnification
        by the Company.
        The
        Company shall, notwithstanding any termination of this Agreement, indemnify
        and
        hold harmless each Purchaser, the officers, directors, partners, members,
        agents, brokers (including brokers who offer and sell Registrable Securities
        as
        principal as a result of a pledge or any failure to perform under a margin
        call
        of Common Stock), investment advisors and employees of each of them, each
        Person
        who controls any such Purchaser (within the meaning of Section 15 of the
        Securities Act or Section 20 of the Exchange Act) and the officers, directors,
        partners, members, agents and employees of each such controlling Person,
        to the
        fullest extent permitted by applicable law, from and against any and all
        Losses,
        as incurred, arising out of or relating to any untrue or alleged untrue
        statement of a material fact contained in the Registration Statement, any
        Prospectus or any form of prospectus or in any amendment or supplement thereto
        or in any preliminary prospectus, or arising out of or relating to any omission
        or alleged omission of a material fact required to be stated therein or
        necessary to make the statements therein (in the case of any Prospectus or
        form
        of prospectus or supplement thereto, in the light of the circumstances under
        which they were made) not misleading, except to the extent, but only to the
        extent, that (i) such untrue statements, alleged untrue statements, omissions
        or
        alleged omissions are based solely upon information regarding such Purchaser
        furnished in writing to the Company by such Purchaser expressly for use therein,
        or to the extent that such information relates to such Purchaser or such
        Purchaser's proposed method of distribution of Registrable Securities and
        was
        reviewed and expressly approved in writing by such Purchaser expressly for
        use
        in the Registration Statement, such Prospectus or such form of Prospectus
        or in
        any amendment or supplement thereto or (ii) in the case of an occurrence
        of an
        event of the type specified in Section 6.2(c)(v)-(vii), the use by such
        Purchaser of an outdated or defective Prospectus after the Company has notified
        such Purchaser in writing that the Prospectus is outdated or defective and
        prior
        to the receipt by such Purchaser of the Advice contemplated in Section 6.5.
        The
        Company shall notify the Purchasers promptly of the institution, threat or
        assertion of any Proceeding of which the Company is aware in connection with
        the
        transactions contemplated by this Agreement.

       

      (b)
         Indemnification
        by Purchasers.
        Each
        Purchaser shall, severally and not jointly, indemnify and hold harmless the
        Company, its directors, officers, agents and employees, each Person who controls
        the Company (within the meaning of Section 15 of the Securities Act and Section
        20 of the Exchange Act), and the directors, officers, agents or employees
        of
        such controlling Persons, to the fullest extent permitted by applicable law,
        from and against all Losses (as determined by a court of competent jurisdiction
        in a final judgment not subject to appeal or review) arising solely out of
        any
        untrue statement of a material fact contained in the Registration Statement,
        any
        Prospectus, or any form of prospectus, or in any amendment or supplement
        thereto, or arising solely out of any omission of a material fact required
        to be
        stated therein or necessary to make the statements therein (in the case of
        any
        Prospectus or form of prospectus or supplement thereto, in the light of the
        circumstances under which they were made) not misleading to the extent, but
        only
        to the extent, that such untrue statement or omission is contained in any
        information so furnished in writing by such Purchaser to the Company
        specifically for inclusion in such Registration Statement or such Prospectus
        or
        to the extent that (i) such untrue statements or omissions are based solely
        upon
        information regarding such Purchaser furnished in writing to the Company
        by such
        Purchaser expressly for use therein, or to the extent that such information
        relates to such Purchaser or such Purchaser's proposed method of distribution
        of
        Registrable Securities and was reviewed and expressly approved in writing
        by
        such Purchaser expressly for use in the Registration Statement, such Prospectus
        or such form of Prospectus or in any amendment or supplement thereto or (ii)
        in
        the case of an occurrence of an event of the type specified in Section
        6.2(c)(v)-(vii),
        the use
        by such Purchaser of an outdated or defective Prospectus after the Company
        has
        notified such Purchaser in writing that the Prospectus is outdated or defective
        and prior to the receipt by such Purchaser of the Advice contemplated in
        Section
        6.5.
        In no
        event shall the liability of any selling Purchaser hereunder be greater in
        amount than the dollar amount of the net proceeds received by such Purchaser
        upon the sale of the Registrable Securities giving rise to such indemnification
        obligation.

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      (c)
         Conduct
        of Indemnification Proceedings.
        If any
        Proceeding shall be brought or asserted against any Person entitled to indemnity
        hereunder (an “Indemnified
        Party”),
        such
        Indemnified Party shall promptly notify the Person from whom indemnity is
        sought
        (the “Indemnifying
        Party”)
        in
        writing, and the Indemnifying Party shall assume the defense thereof, including
        the employment of counsel reasonably satisfactory to the Indemnified Party
        and
        the payment of all fees and expenses incurred in connection with defense
        thereof; provided, that the failure of any Indemnified Party to give such
        notice
        shall not relieve the Indemnifying Party of its obligations or liabilities
        pursuant to this Agreement, except (and only) to the extent that it shall
        be
        finally determined by a court of competent jurisdiction (which determination
        is
        not subject to appeal or further review) that such failure shall have
        proximately and materially adversely prejudiced the Indemnifying
        Party.

       

      An
        Indemnified Party shall have the right to employ separate counsel in any
        such
        Proceeding and to participate in the defense thereof, but the fees and expenses
        of such counsel shall be at the expense of such Indemnified Party or Parties
        unless: (i) the Indemnifying Party has agreed in writing to pay such fees
        and
        expenses; or (ii) the Indemnifying Party shall have failed promptly to assume
        the defense of such Proceeding and to employ counsel reasonably satisfactory
        to
        such Indemnified Party in any such Proceeding; or (iii) the named parties
        to any
        such Proceeding (including any impleaded parties) include both such Indemnified
        Party and the Indemnifying Party, and such Indemnified Party shall have been
        advised by counsel that a conflict of interest is likely to exist if the
        same
        counsel were to represent such Indemnified Party and the Indemnifying Party
        (in
        which case, if such Indemnified Party notifies the Indemnifying Party in
        writing
        that it elects to employ separate counsel at the expense of the Indemnifying
        Party, the Indemnifying Party shall not have the right to assume the defense
        thereof and such counsel shall be at the expense of the Indemnifying Party).
        The
        Indemnifying Party shall not be liable for any settlement of any such Proceeding
        effected without its written consent, which consent shall not be unreasonably
        withheld. No Indemnifying Party shall, without the prior written consent
        of the
        Indemnified Party, effect any settlement of any pending Proceeding in respect
        of
        which any Indemnified Party is a party, unless such settlement includes an
        unconditional release of such Indemnified Party from all liability on claims
        that are the subject matter of such Proceeding.

       

      All
        fees
        and expenses of the Indemnified Party (including reasonable fees and expenses
        to
        the extent incurred in connection with investigating or preparing to defend
        such
        Proceeding in a manner not inconsistent with this Section) shall be paid
        to the
        Indemnified Party, as incurred, within ten Trading Days of written notice
        thereof to the Indemnifying Party (regardless of whether it is ultimately
        determined that an Indemnified Party is not entitled to indemnification
        hereunder; provided, that the Indemnifying Party may require such Indemnified
        Party to undertake to reimburse all such fees and expenses to the extent
        it is
        finally judicially determined that such Indemnified Party is not entitled
        to
        indemnification hereunder). 

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      (d)
         Contribution.
        If a
        claim for indemnification under Section
        6.4(a)
        or
(b)
        is
        unavailable to an Indemnified Party (by reason of public policy or otherwise),
        then each Indemnifying Party, in lieu of indemnifying such Indemnified Party,
        shall contribute to the amount paid or payable by such Indemnified Party
        as a
        result of such Losses, in such proportion as is appropriate to reflect the
        relative fault of the Indemnifying Party and Indemnified Party in connection
        with the actions, statements or omissions that resulted in such Losses as
        well
        as any other relevant equitable considerations. The relative fault of such
        Indemnifying Party and Indemnified Party shall be determined by reference
        to,
        among other things, whether any action in question, including any untrue
        or
        alleged untrue statement of a material fact or omission or alleged omission
        of a
        material fact, has been taken or made by, or relates to information supplied
        by,
        such Indemnifying Party or Indemnified Party, and the parties' relative intent,
        knowledge, access to information and opportunity to correct or prevent such
        action, statement or omission. The amount paid or payable by a party as a
        result
        of any Losses shall be deemed to include, subject to the limitations set
        forth
        in Section
        6.4(c),
        any
        reasonable attorneys' or other reasonable fees or expenses incurred by such
        party in connection with any Proceeding to the extent such party would have
        been
        indemnified for such fees or expenses if the indemnification provided for
        in
        this Section was available to such party in accordance with its
        terms.

       

      The
        parties hereto agree that it would not be just and equitable if contribution
        pursuant to this Section
        6.4(d)
        were
        determined by pro rata allocation or by any other method of allocation that
        does
        not take into account the equitable considerations referred to in the
        immediately preceding paragraph. Notwithstanding the provisions of this Section
        6.4(d), no Purchaser shall be required to contribute, in the aggregate, any
        amount in excess of the amount by which the proceeds actually received by
        such
        Purchaser from the sale of the Registrable Securities subject to the Proceeding
        exceeds the amount of any damages that such Purchaser has otherwise been
        required to pay by reason of such untrue or alleged untrue statement or omission
        or alleged omission. No Person guilty of fraudulent misrepresentation (within
        the meaning of Section 11(f) of the Securities Act) shall be entitled to
        contribution from any Person who was not guilty of such fraudulent
        misrepresentation.

       

      The
        indemnity and contribution agreements contained in this Section are in addition
        to any liability that the Indemnifying Parties may have to the Indemnified
        Parties.

       

      6.5
         Dispositions.
        Each
        Purchaser agrees that it will comply with the prospectus delivery requirements
        of the Securities Act as applicable to it in connection with sales of
        Registrable Securities pursuant to the Registration Statement. Each Purchaser
        further agrees that, upon receipt of a notice from the Company of the occurrence
        of any event of the kind described in Sections
        6.2(c)(v),
        (vi)
        or
(vii),
        such
        Purchaser will discontinue disposition of such Registrable Securities under
        the
        Registration Statement until such Purchaser's receipt of the copies of the
        supplemented Prospectus and/or amended Registration Statement contemplated
        by
Section
        6.2(j),
        or
        until it is advised in writing (the “Advice”)
        by the
        Company that the use of the applicable Prospectus may be resumed, and, in
        either
        case, has received copies of any additional or supplemental filings that
        are
        incorporated or deemed to be incorporated by reference in such Prospectus
        or
        Registration Statement. The Company may provide appropriate stop orders to
        enforce the provisions of this paragraph.

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      6.6
         No
        Piggyback on Registrations.
        Neither
        the Company nor any of its security holders (other than the Purchasers in
        such
        capacity pursuant hereto or Rubenstein Public Relations with respect to not
        more
        than 100,000 shares of Common Stock) may include securities of the Company
        in
        the Registration Statement other than the Registrable Securities, and the
        Company shall not after the date hereof enter into any agreement providing
        any
        such right to any of its security holders.

       

      6.7
         Piggy-Back
        Registrations.
        If at
        any time during the Effectiveness Period there is not an effective Registration
        Statement covering all of the Registrable Securities and the Company shall
        determine to prepare and file with the Commission a registration statement
        relating to an offering for its own account or the account of others under
        the
        Securities Act of any of its equity securities, other than on Form S-4 or
        Form
        S-8 (each as promulgated under the Securities Act) or their then equivalents
        relating to equity securities to be issued solely in connection with any
        acquisition of any entity or business or equity securities issuable in
        connection with stock option or other employee benefit plans, then the Company
        shall send to each Purchaser written notice of such determination and if,

        registered.

      7.1
         Termination.
        This
        Agreement may be terminated by the Company or any Purchaser, by written notice
        to the other parties, if the Closing has not been consummated by the third
        Trading Day following the date of this Agreement; provided that no such
        termination will affect the right of any party to sue for any breach by the
        other party (or parties).

       

      7.2
         Fees
        and Expenses.
        Each
        party shall pay the fees and expenses of its advisers, counsel, accountants
        and
        other experts, if any, and all other expenses incurred by such party incident
        to
        the negotiation, preparation, execution, delivery and performance of this
        Agreement. The Company shall pay all transfer agent fees, stamp taxes and
        other
        taxes and duties levied in connection with the issuance of any Securities
        or the
        execution thereof.

       

      7.3
         Entire
        Agreement.
        The
        Transaction Documents, together with the Exhibits and Schedules thereto,
        contain
        the entire understanding of the parties with respect to the subject matter
        hereof and supersede all prior agreements and understandings, oral or written,
        with respect to such matters, which the parties acknowledge have been merged
        into such documents, exhibits and schedules. At or after the Closing, and
        without further consideration, the Company will execute and deliver to the
        Purchasers such further documents as may be reasonably requested in order
        to
        give practical effect to the intention of the parties under the Transaction
        Documents. Notwithstanding anything to the contrary herein, Securities may
        be
        assigned to any Person in connection with a bona fide margin account or other
        loan or financing arrangement secured by such Company Securities.

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      7.4
         Notices.
        Any and
        all notices or other communications or deliveries required or permitted to
        be
        provided hereunder shall be in writing and shall be deemed given and effective
        on the earliest of (a) the date of transmission, if such notice or communication
        is delivered via facsimile at the facsimile number specified in this Section
        prior to 6:30 p.m. (New York City time) on a Trading Day, (b) the next Trading
        Day after the date of transmission, if such notice or communication is delivered
        via facsimile at the facsimile number specified in this Section on a day
        that is
        not a Trading Day or later than 6:30 p.m. (New York City time) on any Trading
        Day, (c) the Trading Day following the date of deposit with a nationally
        recognized overnight courier service, or (d) upon actual receipt by the party
        to
        whom such notice is required to be given. The addresses and facsimile numbers
        for such notices and communications are those set forth on the signature
        pages
        hereof, or such other address or facsimile number as may be designated in
        writing hereafter, in the same manner, by any such Person.

       

      7.5
         Amendments;
        Waivers.
        No
        provision of this Agreement may be waived or amended except in a written
        instrument signed, in the case of an amendment, by the Company and each of
        the
        Purchasers or, in the case of a waiver, by the party against whom enforcement
        of
        any such waiver is sought. No waiver of any default with respect to any
        provision, condition or requirement of this Agreement shall be deemed to
        be a
        continuing waiver in the future or a waiver of any subsequent default or
        a
        waiver of any other provision, condition or requirement hereof, nor shall
        any
        delay or omission of either party to exercise any right hereunder in any
        manner
        impair the exercise of any such right. Notwithstanding the foregoing, a waiver
        or consent to depart from the provisions hereof with respect to a matter
        that
        relates exclusively to the rights of Purchasers under Article
        VI
        and that
        does not directly or indirectly affect the rights of other Purchasers may
        be
        given by Purchasers holding at least a majority of the Registrable Securities
        to
        which such waiver or consent relates.

       

      7.6
         Construction.
        The
        headings herein are for convenience only, do not constitute a part of this
        Agreement and shall not be deemed to limit or affect any of the provisions
        hereof. The language used in this Agreement will be deemed to be the language
        chosen by the parties to express their mutual intent, and no rules of strict
        construction will be applied against any party.

       

      7.7
         Successors
        and Assigns.
        This
        Agreement shall be binding upon and inure to the benefit of the parties and
        their successors and permitted assigns. The Company may not assign this
        Agreement or any rights or obligations hereunder without the prior written
        consent of the Purchasers. Any Purchaser may assign its rights under this
        Agreement to any Person to whom such Purchaser assigns or transfers any
        Securities, provided such transferee agrees in writing to be bound, with
        respect
        to the transferred Securities, by the provisions hereof that apply to the
        “Purchasers.” Notwithstanding anything to the contrary herein, Securities may be
        assigned to any Person in connection with a bona fide margin account or other
        loan or financing arrangement secured by such Securities.

       

      7.8
         No
        Third-Party Beneficiaries.
        This
        Agreement is intended for the benefit of the parties hereto and their respective
        successors and permitted assigns and is not for the benefit of, nor may any
        provision hereof be enforced by, any other Person, except that each Related
        Person is an intended third party beneficiary of Section 4.4 and each
        Indemnified Party is an intended third party beneficiary of Section 6.4 and
        (in
        each case) may enforce the provisions of such Sections directly against the
        parties with obligations thereunder.

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      7.9
         Governing
        Law; Venue.
        ALL
        QUESTIONS CONCERNING THE CONSTRUCTION, VALIDITY, ENFORCEMENT AND INTERPRETATION
        OF THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE
        WITH THE LAWS OF ENGLAND. THE COMPANY AND PURCHASERS HEREBY IRREVOCABLY SUBMIT
        TO THE EXCLUSIVE JURISDICTION OF THE COMPETANT COURTS SITTING IN
        ENGLAND.

       

      7.10
         Survival.
        The
        representations, warranties, agreements and covenants contained herein shall
        survive the Closing and the delivery and/or exercise of the Securities, as
        applicable. 

       

      7.11
         Execution.
        This
        Agreement may be executed in two or more counterparts, all of which when
        taken
        together shall be considered one and the same agreement and shall become
        effective when counterparts have been signed by each party and delivered
        to the
        other party, it being understood that both parties need not sign the same
        counterpart. In the event that any signature is delivered by facsimile
        transmission, such signature shall create a valid and binding obligation
        of the
        party executing (or on whose behalf such signature is executed) with the
        same
        force and effect as if such facsimile signature page were an original
        thereof.

       

      7.12
         Severability.
        If any
        provision of this Agreement is held to be invalid or unenforceable in any
        respect, the validity and enforceability of the remaining terms and provisions
        of this Agreement shall not in any way be affected or impaired thereby and
        the
        parties will attempt to agree upon a valid and enforceable provision that
        is a
        reasonable substitute therefor, and upon so agreeing, shall incorporate such
        substitute provision in this Agreement.

       

      7.13
         Replacement
        of Securities.
        If any
        certificate or instrument evidencing any Securities is mutilated, lost, stolen
        or destroyed, the Company shall issue or cause to be issued in exchange and
        substitution for and upon cancellation thereof, or in lieu of and substitution
        therefor, a new certificate or instrument, but only upon receipt of evidence
        reasonably satisfactory to the Company of such loss, theft or destruction
        and
        customary and reasonable indemnity, if requested. The applicants for a new
        certificate or instrument under such circumstances shall also pay any reasonable
        third-party costs associated with the issuance of such replacement
        Securities.

       

      7.14
         Remedies.
        In
        addition to being entitled to exercise all rights provided herein or granted
        by
        law, including recovery of damages, each of the Purchasers and the Company
        will
        be entitled to specific performance under the Transaction Documents. The
        parties
        agree that monetary damages may not be adequate compensation for any loss
        incurred by reason of any breach of obligations described in the foregoing
        sentence and hereby agrees to waive in any action for specific performance
        of
        any such obligation the defense that a remedy at law would be
        adequate.

       

      7.15
         Adjustments
        in Share Numbers and Prices.
        In the
        event of any stock split, subdivision, dividend or distribution payable in
        shares of Common Stock (or other securities or rights convertible into, or
        entitling the holder thereof to receive directly or indirectly shares of
        Common
        Stock), combination or other similar recapitalization or event occurring
        after
        the date hereof, each reference in any Transaction Document to a number of
        shares or a price per share shall be amended to appropriately account for
        such
        event.

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      7.16
         Independent
        Nature of Purchasers' Obligations and Rights.
        The
        obligations of each Purchaser under any Transaction Document are several
        and not
        joint with the obligations of any other Purchaser, and no Purchaser shall
        be
        responsible in any way for the performance of the obligations of any other
        Purchaser under any Transaction Document. The decision of each Purchaser
        to
        purchase Securities pursuant to this Agreement has been made by such Purchaser
        independently of any other Purchaser and independently of any information,
        materials, statements or opinions as to the business, affairs, operations,
        assets, properties, liabilities, results of operations, condition (financial
        or
        otherwise) or prospects of the Company or of the Subsidiary which may have
        been
        made or given by any other Purchaser or by any agent or employee of any other
        Purchaser, and no Purchaser or any of its agents or employees shall have
        any
        liability to any other Purchaser (or any other person) relating to or arising
        from any such information, materials, statements or opinions. Nothing contained
        herein or in any Transaction Document, and no action taken by any Purchaser
        pursuant thereto, shall be deemed to constitute the Purchasers as a partnership,
        an association, a joint venture or any other kind of entity, or create a
        presumption that the Purchasers are in any way acting in concert or as a
        group
        with respect to such obligations or the transactions contemplated by the
        Transaction Document. The Company hereby confirms that it understands and
        agrees
        that the Purchasers are not acting as a “group” as that term is used in Section
        13(d) of the Exchange Act. Each Purchaser acknowledges that no other Purchaser
        has acted as agent for such Purchaser in connection with making its investment
        hereunder and that no other Purchaser will be acting as agent of such Purchaser
        in connection with monitoring its investment hereunder. Each Purchaser shall
        be
        entitled to independently protect and enforce its rights, including without
        limitation the rights arising out of this Agreement or out of the other
        Transaction Documents, and it shall not be necessary for any other Purchaser
        to
        be joined as an additional party in any proceeding for such purpose. Each
        Purchaser represents that it has been represented by its own separate legal
        counsel in its review and negotiations of this Agreement and the Transaction
        Documents.

       

      7.17
         Announcements. The
        Company undertakes not to make any public announcements about the subject
        matter
        hereof without the prior written consent of each of the Purchasers, except
        as
        required by any laws, regulations or the rules of any Trading Market, in
        which
        case the Purchasers would be informed in advance about the timing and content
        of
        the announcement.

        and
        including the third anniversary of the date hereof (the “Expiration
        Date”),
        and
        subject to the following terms and conditions. This Warrant (this “Warrant”)
        is one
        of a series of similar warrants issued pursuant to that certain Amendment
        No. 1
        to Securities Purchase Agreements and Warrants, dated as of the date hereof,
        by
        and among the Company and the Purchasers identified therein (the “Amendment”).
        All
        such warrants are referred to herein, collectively, as the “Warrants.”

       

      1.
         Definitions.
        In
        addition to the terms defined elsewhere in this Warrant, capitalized terms
        that
        are not otherwise defined herein have the meanings given to such terms in
        the
        Securities Purchase Agreement, dated as of June 14, 2004 among the Company

            Equal to
            100% (aggregate) warrant coverage of the number of Warrants exercised
            pursuant
            to Amendment

      2.
         Registration
        of Warrant.
        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.

       

      3.
         Registration
        of Transfers.
        The
        Company shall register the transfer of any portion of this Warrant in the
        Warrant Register, upon surrender of this Warrant, with the Form of Assignment
        attached hereto duly completed and signed, to the Transfer Agent or to the
        Company at its address specified herein. Upon any such registration or transfer,
        a new warrant to purchase Common Stock, in substantially the form of this
        Warrant (any such new warrant, a “New
        Warrant”),
        evidencing the portion of this Warrant so transferred shall be issued to
        the
        transferee and a New Warrant evidencing the remaining portion of this Warrant
        not so transferred, if any, shall be issued to the transferring Holder. The
        acceptance of the New Warrant by the transferee thereof shall be deemed the
        acceptance by such transferee of all of the rights and obligations of a holder
        of a Warrant.

       

      4.
         Exercise
        and Duration of Warrants.

       

      (a)
         This
        Warrant shall be exercisable by the registered Holder at any time and from
        time
        to time on or after the date hereof to and including the Expiration Date.
        At
        6:30 P.M., New York City time on the Expiration Date, the portion of this
        Warrant not exercised prior thereto shall be and become void and of no value;
        provided that, if the average of the Closing Prices for the five Trading
        Days
        immediately prior to (but not including) the Expiration Date exceeds the
        Exercise Price on the Expiration Date, then this Warrant shall be deemed
        to have
        been exercised in full (to the extent not previously exercised) on a “cashless
        exercise” basis at 6:30 P.M. New York City time on the Expiration Date if a
“cashless exercise” may occur at such time pursuant to Section 10 below.
        Notwithstanding anything to the contrary herein, the Expiration Date shall
        be
        extended for each day following the Effective Date that the Registration
        Statement is not effective.

       

      (b)
         A
        Holder
        may exercise this Warrant by delivering to the Company (i) an exercise notice,
        in the form attached hereto (the “Exercise
        Notice”),
        appropriately completed and duly signed, and (ii) payment of the Exercise
        Price for the number of Warrant Shares as to which this Warrant is being
        exercised (which may take the form of a “cashless exercise” if so indicated in
        the Exercise Notice and if a “cashless exercise” may occur at such time pursuant
        to this Section 10 below), and the date such items are delivered to the Company
        (as determined in accordance with the notice provisions hereof) is an
“Exercise
        Date.”
The
        Holder shall not be required to deliver the original Warrant in order to
        effect
        an exercise hereunder. Upon the execution and delivery of the Exercise Notice,
        the Company shall issue a New Warrant to the Holder evidencing the right
        to
        purchase the remaining number of Warrant Shares.

       

      
        
           

        

        
          2

          
            

          

        

        
           

        

      

       

      5.
         Delivery
        of Warrant Shares.
        

       

      (a)
         Upon
        exercise of this Warrant, the Company shall promptly (but in no event later
        than
        three (3) Trading Days after the Exercise Date) issue or cause to be issued
        and
        cause to be delivered to or upon the written order of the Holder and in such
        name or names as the Holder may designate, a certificate for the Warrant
        Shares
        issuable upon such exercise, free of restrictive legends unless a registration
        statement covering the resale of the Warrant Shares and naming the Holder
        as a
        selling stockholder thereunder is not then effective and the Warrant Shares
        are
        not freely transferable without volume restrictions pursuant to Rule 144
        under
        the Securities Act. The Holder, or any Person so designated by the Holder
        to
        receive Warrant Shares, shall be deemed to have become holder of record of
        such
        Warrant Shares as of the Exercise Date. The Company shall, upon request of
        the
        Holder, use its best efforts to deliver Warrant Shares hereunder electronically
        through the Depository Trust Corporation or another established clearing
        corporation performing similar functions.

       

      (b)
         This
        Warrant is exercisable, either in its entirety or, from time to time, for
        a
        portion of the number of Warrant Shares. Upon surrender of this Warrant
        following one or more partial exercises, the Company shall issue or cause
        to be
        issued, at its expense, a New Warrant evidencing the right to purchase the
        remaining number of Warrant Shares.

       

      (c)
         In
        addition to any other rights available to a Holder, if the Company fails
        to
        deliver to the Holder a certificate representing Warrant Shares by the third
        Trading Day after the date on which delivery of such certificate is required
        by
        this Warrant, and if after such third Trading Day the Holder purchases (in
        an
        open market transaction or otherwise) shares of Common Stock to deliver in
        satisfaction of a sale by the Holder of the Warrant Shares that the Holder
        anticipated receiving from the Company (a “Buy-In”),
        then
        the Company shall, within three (3)Trading Days after the Holder’s request and
        in the Holder's discretion, either (i) pay cash to the Holder in an amount
        equal
        to the Holder’s total purchase price (including brokerage commissions, if any)
        for the shares of Common Stock so purchased (the “Buy-In
        Price”),
        at
        which point the Company’s obligation to deliver such certificate (and to issue
        such Common Stock) shall terminate, or (ii) promptly honor its obligation
        to
        deliver to the Holder a certificate or certificates representing such Common
        Stock and pay cash to the Holder in an amount equal to the excess (if any)
        of
        the Buy-In Price over the product of (A) such number of shares of Common
        Stock,
        times (B) the Closing Price on the date of the event giving rise to the
        Company’s obligation to deliver such certificate.

       

      (d)
         The
        Company’s obligations to issue and deliver Warrant Shares in accordance with the
        terms hereof are absolute and unconditional, irrespective of any action or
        inaction by the Holder to enforce the same, any waiver or consent with respect
        to any provision hereof, the recovery of any judgment against any Person
        or any
        action to enforce the same, or any setoff, counterclaim, recoupment, limitation
        or termination, or any breach or alleged breach by the Holder or any other
        Person of any obligation to the Company or any violation or alleged violation
        of
        law by the Holder or any other Person, and irrespective of any other
        circumstance which might otherwise limit such obligation of the Company to
        the
        Holder in connection with the issuance of Warrant Shares. Nothing herein
        shall
        limit a Holder’s right to pursue any other remedies available to it hereunder,
        at law or in equity including, without limitation, a decree of specific
        performance and/or injunctive relief with respect to the Company’s failure to
        timely deliver certificates representing shares of Common Stock upon exercise
        of
        the Warrant as required pursuant to the terms hereof.

      6.
         Charges,
        Taxes and Expenses.
        Issuance and delivery of certificates for shares of Common Stock upon exercise
        of this Warrant shall be made without charge to the Holder for any issue
        or
        transfer tax, withholding tax, transfer agent fee or other incidental tax
        or
        expense in respect of the issuance of such certificates, all of which taxes
        and
        expenses shall be paid by the Company; 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 registration of any certificates for Warrant Shares or Warrants
        in a name other than that of the Holder or an Affiliate thereof. The Holder
        shall be responsible for all other tax liability that may arise as a result
        of
        holding or transferring this Warrant or receiving Warrant Shares upon exercise
        hereof.

       

      7.
         Replacement
        of Warrant.
        If this
        Warrant is mutilated, lost, stolen or destroyed, the Company shall issue
        or
        cause to be issued in exchange and substitution for and upon cancellation
        hereof, or in lieu of and substitution for this Warrant, a New Warrant, but
        only
        upon receipt of evidence reasonably satisfactory to the Company of such loss,
        theft or destruction and customary and reasonable bond or indemnity, if
        requested. Applicants for a New Warrant under such circumstances shall also
        comply with such other reasonable regulations and procedures and pay such
        other
        reasonable third-party costs as the Company may prescribe.

       

      8.
         Reservation
        of Warrant Shares.
        The
        Company covenants that it will at all times reserve and keep available out
        of
        the aggregate of its authorized but unissued and otherwise unreserved Common
        Stock, solely for the purpose of enabling it to issue Warrant Shares upon
        exercise of this Warrant as herein provided, the number of Warrant Shares
        which
        are then issuable and deliverable upon the exercise of this entire Warrant,
        free
        from preemptive rights or any other contingent purchase rights of persons
        other
        than the Holder (taking into account the adjustments and restrictions of
        Section
        9).
        The
        Company covenants that all Warrant Shares so issuable and deliverable shall,
        upon issuance and the payment of the applicable Exercise Price in accordance
        with the terms hereof, be duly and validly authorized, issued and fully paid
        and
        nonassessable. The Company will take all such actions as may be necessary
        to
        assure that such shares of Common Stock may be issued as provided herein
        without
        violation of any applicable law or regulation, or of any requirements of
        any
        securities exchange or automated quotation system upon which the Common Stock
        may be listed.

       

      9.
         Certain
        Adjustments.
        The
        Exercise Price and number of Warrant Shares issuable upon exercise of this
        Warrant are subject to adjustment from time to time as set forth in this
        Section
        9.

       

      (a)
         Stock
        Dividends and Splits.
        If the
        Company, at any time while this Warrant is outstanding, (i) pays a stock
        dividend on its Common Stock or otherwise makes a distribution on any class
        of
        capital stock that is payable in shares of Common Stock, (ii) subdivides
        outstanding shares of Common Stock into a larger number of shares, or (iii)
        combines outstanding shares of Common Stock into a smaller number of shares,
        then in each such case the Exercise Price shall be multiplied by a fraction
        of
        which the numerator shall be the number of shares of Common Stock outstanding
        immediately before such event and of which the denominator shall be the number
        of shares of Common Stock outstanding immediately after such event. Any
        adjustment made pursuant to clause (i) of this paragraph shall become effective
        immediately after the record date for the determination of stockholders entitled
        to receive such dividend or distribution, and any adjustment pursuant to
        clause
        (ii) or (iii) of this paragraph shall become effective immediately after
        the
        effective date of such subdivision or combination.

       

      
        
           

        

        
          4

          
            

          

        

        
           

        

      

       

      (b)
         Pro
        Rata Distributions.
        If the
        Company, at any time while this Warrant is outstanding, distributes to all
        holders of Common Stock (i) evidences of its indebtedness, (ii) any security
        (other than a distribution of Common Stock covered by the preceding paragraph),
        (iii) rights or warrants to subscribe for or purchase any security, or (iv)
        any other asset (in each case, “Distributed
        Property”),
        then
        in each such case the Exercise Price in effect immediately prior to the record
        date fixed for determination of stockholders entitled to receive such
        distribution shall be adjusted (effective on such record date) to equal the
        product of such Exercise Price times a fraction of which the denominator
        shall
        be the average of the Closing Prices for the five Trading Days immediately
        prior
        to (but not including) such record date and of which the numerator shall
        be such
        average less the then fair market value of the Distributed Property distributed
        in respect of one outstanding share of Common Stock, as determined by the
        Company's independent certified public accountants that regularly examine
        the
        financial statements of the Company (an “Appraiser”).
        In
        such event, the Holder, after receipt of the determination by the Appraiser,
        shall have the right to select an additional appraiser (which shall be a
        nationally recognized accounting firm), in which case such fair market value
        shall be deemed to equal the average of the values determined by each of
        the
        Appraiser and such appraiser. As an alternative to the foregoing adjustment
        to
        the Exercise Price, at the request of the Holder delivered before the 90th
        day
        after such record date the Company will deliver to such Holder, within five
        Trading Days after such request (or, if later, on the effective date of such
        distribution), the Distributed Property that such Holder would have been
        entitled to receive in respect of the Warrant Shares for which this Warrant
        could have been exercised immediately prior to such record date. If such
        Distributed Property is not delivered to a Holder pursuant to the preceding
        sentence, then upon expiration of or any exercise of the Warrant that occurs
        after such record date, such Holder shall remain entitled to receive, in
        addition to the Warrant Shares otherwise issuable upon such exercise (if
        applicable), such Distributed Property. 

       

      (c)
         Fundamental
        Transactions.
        If, at
        any time while this Warrant is outstanding, (i) the Company effects any merger
        or consolidation of the Company with or into another Person, (ii) the Company
        effects any sale of all or substantially all of its assets in one or a series
        of
        related transactions, (iii) any tender offer or exchange offer (whether by
        the
        Company or another Person) is completed pursuant to which holders of Common
        Stock are permitted to tender or exchange their shares for other securities,
        cash or property, or (iv) the Company effects any reclassification of the
        Common
        Stock or any compulsory share exchange pursuant to which the Common Stock
        is
        effectively converted into or exchanged for other securities, cash or property
        (other than as a result of a subdivision or combination of shares of Common
        Stock covered by Section 9(a) above) (in any such case, a “Fundamental
        Transaction”),
        then
        the Holder shall have the right thereafter to receive, upon exercise of this
        Warrant, the same amount and kind of securities, cash or property as it would
        have been entitled to receive upon the occurrence of such Fundamental
        Transaction if it had been, immediately prior to such Fundamental Transaction,
        the holder of the number of Warrant Shares then issuable upon exercise in
        full
        of this Warrant (the “Alternate
        Consideration”).
        The
        aggregate Exercise Price for this Warrant will not be affected by any such
        Fundamental Transaction, but the Company shall apportion such aggregate Exercise
        Price among the Alternate Consideration in a reasonable manner reflecting
        the
        relative value of any different components of the Alternate Consideration.
        If
        holders of Common Stock are given any choice as to the securities, cash or
        property to be received in a Fundamental Transaction, then the Holder shall
        be
        given the same choice as to the Alternate Consideration it receives upon
        any
        exercise of this Warrant following such Fundamental Transaction. In the event
        of
        a Fundamental Transaction, the Company or the successor or purchasing Person,
        as
        the case may be, shall execute with the Holder a written agreement providing
        that:

       

      
        
           

        

        
          5

          
            

          

        

        
           

        

      

      

      (x)
         this
        Warrant shall thereafter entitle the Holder to purchase the Alternate
        Consideration in accordance with this section 9(c), 

      

      (y) in
        the
        case of any such successor or purchasing Person, upon such consolidation,
        merger, statutory exchange, combination, sale or conveyance such successor
        or
        purchasing Person shall be jointly and severally liable with the Company
        for the
        performance of all of the Company's obligations under this Warrant and the
        Purchase Agreement, and 

      

      (z) if
        registration or qualification is required under the Exchange Act or applicable
        state law for the public resale by the Holder of shares of stock and other
        securities so issuable upon exercise of this Warrant, all rights applicable
        to
        registration of the Common Stock issuable upon exercise of this Warrant shall
        apply to the Alternate Consideration. 

      

      If,
        in
        the case of any Fundamental Transaction, the Alternate Consideration includes
        shares of stock, other securities, other property or assets of a Person other
        than the Company or any such successor or purchasing Person, as the case
        may be,
        in such Fundamental Transaction, then such written agreement shall also be
        executed by such other Person and shall contain such additional provisions
        to
        protect the interests of the Holder as the Board of Directors of the Company
        shall reasonably consider necessary by reason of the foregoing. At the Holder’s
        request, any successor to the Company or surviving entity in such Fundamental
        Transaction shall issue to the Holder a new warrant consistent with the
        foregoing provisions and evidencing the Holder’s right to purchase the Alternate
        Consideration for the aggregate Exercise Price upon exercise thereof. The
        terms
        of any agreement pursuant to which a Fundamental Transaction is effected
        shall
        include terms requiring any such successor or surviving entity to comply
        with
        the provisions of this paragraph (c) and insuring that the Warrant (or any
        such
        replacement security) will be similarly adjusted upon any subsequent transaction
        analogous to a Fundamental Transaction. If any Fundamental Transaction
        constitutes or results in a Change of Control, then at the request of the
        Holder
        delivered before the 90th
        day
        after such Fundamental Transaction, the Company (or any such successor or
        surviving entity) will purchase the Warrant from the Holder for a purchase
        price, payable in cash within five Trading Days after such request (or, if
        later, on the effective date of the Fundamental Transaction), equal to the
        Black-Scholes value of the remaining unexercised portion of this Warrant
        on the
        date of such request.

       

      (d)
         Number
        of Warrant Shares.
        Simultaneously with any adjustments to the Exercise Price pursuant to paragraphs
        (a) or (b) of this Section, the number of Warrant Shares that may be purchased
        upon exercise of this Warrant shall be increased or decreased proportionately,
        so that after such adjustment the aggregate Exercise Price payable hereunder
        for
        the increased or decreased number of Warrant Shares shall be the same as
        the
        aggregate Exercise Price in effect immediately prior to such
        adjustment.

      (e)
         Calculations.
        All
        calculations under this Section
        9
        shall be
        made to the nearest cent or the nearest 1/100th of a share, as applicable.
        The
        number of shares of Common Stock outstanding at any given time shall not
        include
        shares owned or held by or for the account of the Company, and the disposition
        of any such shares shall be considered an issue or sale of Common
        Stock.

       

      (f)
         Notice
        of Adjustments.
        Upon
        the occurrence of each adjustment pursuant to this Section
        9,
        the
        Company at its expense will promptly compute such adjustment in accordance
        with
        the terms of this Warrant and prepare a certificate setting forth such
        adjustment, including a statement of the adjusted Exercise Price and adjusted
        number or type of Warrant Shares or other securities issuable upon exercise
        of
        this Warrant (as applicable), describing the transactions giving rise to
        such
        adjustments and showing in detail the facts upon which such adjustment is
        based.
        Upon written request, the Company will promptly deliver a copy of each such
        certificate to the Holder and to the Company’s Transfer Agent.

       

      (g)
         Notice
        of Corporate Events.
        If the
        Company (i) declares a dividend or any other distribution of cash, securities
        or
        other property in respect of its Common Stock, including without limitation
        any
        granting of rights or warrants to subscribe for or purchase any capital stock
        of
        the Company or any Subsidiary, (ii) authorizes or approves, enters into any
        agreement contemplating or solicits stockholder approval for any Fundamental
        Transaction or (iii) authorizes the voluntary dissolution, liquidation or
        winding up of the affairs of the Company, then the Company shall deliver
        to the
        Holder a notice describing the material terms and conditions of such
        transaction, at least 20 calendar days prior to the applicable record or
        effective date on which a Person would need to hold Common Stock in order
        to
        participate in or vote with respect to such transaction, and the Company
        will
        take all steps reasonably necessary in order to insure that the Holder is
        given
        the practical opportunity to exercise this Warrant prior to such time so
        as to
        participate in or vote with respect to such transaction; provided, however,
        that
        the failure to deliver such notice or any defect therein shall not affect
        the
        validity of the corporate action required to be described in such notice.
        

       

      10.
         Payment
        of Exercise Price.
        The
        Holder shall pay the Exercise Price in immediately available funds; provided,
        however, if at anytime after the Required Effectiveness Date there is no
        effective Registration Statement registering, or no current prospectus available
        for, the resale of the Warrant Shares by the Holder, the Holder may satisfy
        its
        obligation to pay the Exercise Price through a “cashless exercise,” in which
        event the Company shall issue to the Holder the number of Warrant Shares
        determined as follows:

       

      
        	 	
                X
                  =
                  Y [(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 arithmetic average of the Closing Prices for the five Trading
                  Days
                  immediately prior to (but not including) the Exercise
                  Date.

              
	 	 
	 	
                B
                  =
                  the Exercise Price.

      For
        purposes of Rule 144 promulgated under the Securities Act, it is intended,
        understood 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 shall be deemed to have commenced,
        on
        the date this Warrant was originally issued pursuant to the Purchase
        Agreement.

      

      11.
         Limitation
        on Exercise.
        (a)
        Notwithstanding anything to the contrary contained herein, the
        number of shares of Common Stock that may be acquired by the Holder upon
        any
        exercise of this Warrant (or otherwise in respect hereof) shall be limited
        to
        the extent necessary to insure that, following such exercise (or other
        issuance), the total number of shares of Common Stock then beneficially owned
        by
        such Holder and its Affiliates and any other Persons whose beneficial ownership
        of Common Stock would be aggregated with the Holder’s for purposes of Section
        13(d) of the Exchange Act, does not exceed 4.999% (the “Threshold
        Percentage”)
        or
        9.999% (the “Maximum
        Percentage”)
        of the
        total number of issued and outstanding shares of Common Stock (including
        for
        such purpose the shares of Common Stock issuable upon such
        exercise).
        For such
        purposes, beneficial ownership shall be determined in accordance with Section
        13(d) of the Exchange Act and the rules and regulations promulgated thereunder.
        Each delivery of an Exercise Notice hereunder will constitute a representation
        by the Holder that it has evaluated the limitations set forth in this paragraph
        and determined that issuance of the full number of Warrant Shares requested
        in
        such Exercise Notice is permitted under this paragraph. The Company’s obligation
        to issue shares of Common Stock in excess of the limitation referred to in
        this
        Section shall be suspended (and shall not terminate or expire notwithstanding
        any contrary provisions hereof) until such time, if any, as such shares of
        Common Stock may be issued in compliance with such limitation. By written
        notice
        to the Company, the Holder shall have the right (x) at any time and from
        time to
        time to reduce its Maximum Percentage immediately upon notice to the Company
        in
        the event and only to the extent that Section 16 of the Exchange Act or the
        rules promulgated thereunder (or any successor statute or rules) is changed
        to
        reduce the beneficial ownership percentage threshold thereunder to a percentage
        less than 9.999% and (y) at any time and from time to time, to waive the
        provisions of this Section insofar as they relate to the Threshold Percentage
        or
        to increase or decrease its Threshold Percentage (but not in excess of the
        Maximum Percentage) unless the Holder shall have, by written instrument
        delivered to the Company, irrevocably waived its rights to so increase or
        decrease its Threshold Percentage, but (i) any such waiver, increase or decrease
        will not be effective until the 61st day after such notice is delivered to
        the
        Company, and (ii) any such waiver or increase or decrease will apply only
        to the
        Holder and not to any other holder of Warrants.

       

      (b) Notwithstanding
        anything to the contrary contained herein the maximum number of shares of
        Common
        Stock that the Company may issue pursuant to the Transaction Documents at
        an
        effective purchase price less than the Closing Price on the Trading Day
        immediately preceding the Closing Date equals 19.99% of the outstanding shares
        of Common Stock immediately preceding the Closing Date (the “Issuable
        Maximum”),
        unless the Company obtains shareholder approval in accordance with the rules
        and
        regulations of such Trading Market, if applicable. If, at the time any Holder
        requests an exercise of any of the Warrants, the Actual Minimum (excluding
        any
        shares issued or issuable at an effective purchase price in excess of the
        Closing Price on the Trading Day immediately preceding the Closing Date)
        exceeds
        the Issuable Maximum (and if the Company has not previously obtained the
        required shareholder approval), then the Company shall issue to the Holder
        requesting such exercise a number of shares of Common Stock not exceeding
        such
        Holder’s pro-rata portion of the Issuable Maximum (based on such Holder’s share
        (vis-à-vis other Holders) of the aggregate purchase price paid under the
        Purchase Agreement and taking into account any Warrant Shares previously
        issued
        to such Holder). For the purposes hereof, “Actual
        Minimum”
shall
        mean, as of any date, the maximum aggregate number of shares of Common Stock
        then issued or potentially issuable in the future pursuant to the Transaction
        Documents, including any Underlying Shares issuable upon exercise in full
        of all
        Warrants, without giving effect to any limits on the number of shares of
        Common
        Stock that may be owned by a Holder at any one time.

      12.
         Fractional
        Shares.
        The
        Company shall not be required to issue or cause to be issued fractional Warrant
        Shares on the exercise of this Warrant. If any fraction of a Warrant Share
        would, except for the provisions of this Section, be issuable upon exercise
        of
        this Warrant, the number of Warrant Shares to be issued will be rounded up
        to
        the nearest whole share.

       

      13.
         Notices.
        Any and
        all notices or other communications or deliveries hereunder (including without
        limitation any Exercise Notice) shall be in writing and shall be deemed given
        and effective on the earliest of (i) the date of transmission, if such notice
        or
        communication is delivered via facsimile at the facsimile number specified
        in
        this Section prior to 6:30 p.m. (New York City time) on a Trading Day, (ii)
        the
        next Trading Day after the date of transmission, if such notice or communication
        is delivered via facsimile at the facsimile number specified in this Section
        on
        a day that is not a Trading Day or later than 6:30 p.m. (New York City time)
        on
        any Trading Day, (iii) the Trading Day following the date of mailing, if
        sent by
        nationally recognized overnight courier service, or (iv) upon actual receipt
        by
        the party to whom such notice is required to be given. The address for such
        notices or communications shall be as set forth in the Amendment.

       

      14.
         Warrant
        Agent.
        The
        Company shall serve as warrant agent under this Warrant. Upon 30 days' notice
        to
        the Holder, the Company may appoint a new warrant agent. Any corporation
        into
        which the Company or any new warrant agent may be merged or any corporation
        resulting from any consolidation to which the Company or any new warrant
        agent
        shall be a party or any corporation to which the Company or any new warrant
        agent transfers substantially all of its corporate trust or shareholders
        services business shall be a successor warrant agent under this Warrant without
        any further act. Any such successor warrant agent shall promptly cause notice
        of
        its succession as warrant agent to be mailed (by first class mail, postage
        prepaid) to the Holder at the Holder's last address as shown on the Warrant
        Register.

       

      15.
         Miscellaneous.

       

      (a)
         Subject
        to the restrictions on transfer set forth on the first page hereof, this
        Warrant
        may be assigned by the Holder. This Warrant may not be assigned by the Company
        except to a successor in the event of a Fundamental Transaction. This Warrant
        shall be binding on and inure to the benefit of the parties hereto and their
        respective successors and assigns. Subject to the preceding sentence, nothing
        in
        this Warrant shall be construed to give to any Person other than the Company
        and
        the Holder any legal or equitable right, remedy or cause of action under
        this
        Warrant. This Warrant may be amended only in writing signed by the Company
        and
        the Holder and their successors and assigns.

      (b)
         The
        Company will not, by amendment of its governing documents 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 action as may be necessary or appropriate in order to
        protect
        the rights of the Holder against impairment. Without limiting the generality
        of
        the foregoing, the Company (i) will not increase the par value of any Warrant
        Shares above the amount payable therefor on such exercise, (ii) will take
        all
        such action as may be reasonably necessary or appropriate in order that the
        Company may validly and legally issue fully paid and nonassessable Warrant
        Shares on the exercise of this Warrant, and (iii) will not close its shareholder
        books or records in any manner which interferes with the timely exercise
        of this
        Warrant.

       

      
        (c)  
          GOVERNING LAW; VENUE; WAIVER OF JURY TRIAL.
          ALL
          QUESTIONS CONCERNING THE CONSTRUCTION, VALIDITY, ENFORCEMENT AND INTERPRETATION
          OF THIS WARRANT SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE
          WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO THE
          PRINCIPLES OF CONFLICTS OF LAW THEREOF. EACH PARTY AGREES THAT ALL LEGAL
          PROCEEDINGS CONCERNING THE INTERPRETATIONS, ENFORCEMENT AND DEFENSE OF

          BROUGHT
          AGAINST A PARTY HERETO OR ITS RESPECTIVE AFFILIATES, DIRECTORS, OFFICERS,
          SHAREHOLDERS, EMPLOYEES OR AGENTS) SHALL BE COMMENCED EXCLUSIVELY IN THE

          AGREES NOT TO ASSERT IN ANY SUIT, ACTION OR PROCEEDING, ANY CLAIM THAT
          IT IS NOT
          PERSONALLY SUBJECT TO THE JURISDICTION OF ANY SUCH COURT, THAT SUCH SUIT,

          PERSONAL
          SERVICE OF PROCESS AND CONSENTS TO PROCESS BEING SERVED IN ANY SUCH SUIT,
          ACTION

          EFFECT FOR NOTICES TO IT UNDER THIS WARRANT AND AGREES THAT SUCH SERVICE
          SHALL

          IF EITHER PARTY SHALL COMMENCE AN ACTION OR PROCEEDING TO ENFORCE ANY PROVISIONS
          OF THIS WARRANT OR ANY TRANSACTION DOCUMENT, THEN THE PREVAILING PARTY
          IN SUCH
          ACTION OR PROCEEDING SHALL BE REIMBURSED BY THE OTHER PARTY FOR ITS REASONABLE
