      The
      Company hereby represents and warrants to each of the Purchasers as
      follows:

     

    (a)    Organization
      and Qualification.
      The
      Company is an entity duly organized, validly existing and in good standing
      under
      the laws of the jurisdiction of its incorporation, with the requisite power
      and
      authority to own and use its properties and assets and to carry on its business
      as currently conducted. The Company is not in violation of any of the provisions
      of its articles of incorporation, bylaws or other organizational or charter
      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
      may
      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, or
      (iii) adversely impair the Company's ability to perform fully on a timely basis
      its obligations under any of the Transaction Documents (any of (i), (ii) or
      (iii), a “Material
      Adverse Effect”).

     

    (b)    Authorization;
      Enforcement.
      The
      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.

     

    
      
        
        

      

      
        5

        
          

        

      

      
        
        

      

    

     

    (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
      notice or lapse of time or both would become a default) under, or give to 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
      other understanding to which the Company is a party or by which any property
      or
      asset of the Company is bound or affected, or (iii) result in a violation of
      any
      law, rule, regulation, order, judgment, injunction, decree or other restriction
      of any court or governmental authority to which the Company is subject
      (including federal and state securities laws and regulations and the rules
      and
      regulations of any self-regulatory organization to which the Company or its
      securities are subject), or by which any property or asset of the Company is
      bound or affected.

     

    (d)    Issuance
      of the Securities.
      The
      Securities (including the Underlying Shares) are duly authorized and, when
      issued and paid for in accordance with the Transaction Documents, will be duly
      and validly issued, fully paid and nonassessable, free and clear of all Liens
      and shall not be subject to preemptive rights or similar rights of shareholders.
      The Company has reserved from its duly authorized capital stock the maximum
      number of shares of Common Stock issuable upon exercise of the
      Warrants.

     

    (e)    Capitalization.
      The
      Company has no outstanding shares of capital stock other than its Common Stock.
      All outstanding shares of Common Stock have been duly authorized, validly
      issued, fully paid and nonassessable and have been issued in compliance with
      all
      applicable laws. Except as disclosed in the SEC Reports, there are no
      outstanding options, warrants, script rights to subscribe to, calls or
      commitments of any character whatsoever relating to, or securities, rights
      or
      obligations convertible into or exercisable or exchangeable for, or giving
      any
      Person any right to subscribe for or acquire, any shares of Common Stock, or
      contracts, commitments, understandings or arrangements by which the Company
      is
      bound to issue additional shares of Common Stock, or securities or rights
      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, 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

      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.

    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.

    4.4    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.

      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.

    6.2    Registration
      Procedures.
      In
      connection with the Company's registration obligations hereunder, the Company
      shall:

     

    (a)    Not
      less
      than three Trading Days prior to the filing of a Registration Statement or
      any
      related Prospectus or any amendment or supplement thereto (including any
      document that would be incorporated or deemed to be incorporated therein by
      reference), the Company shall (i) furnish to each Purchaser and any counsel
      designated by any Purchaser (each, a “Purchaser
      Counsel”),
      copies of all such documents proposed to be filed, which documents (other than
      those incorporated or deemed to be incorporated by reference) will be subject
      to
      the review of such Purchaser’s and Purchaser Counsel (it being understood that
      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,
      in the reasonable opinion of respective counsel, to conduct a reasonable
      investigation within the meaning of the Securities Act. 

     

    (b)    (i)
      Prepare and file with the Commission such amendments, including post-effective
      amendments, to each Registration Statement and the Prospectus used in connection
      therewith as may be necessary to keep the Registration Statement continuously
      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
      supplemented by any required Prospectus supplement, and as so supplemented
      or
      amended to be filed pursuant to Rule 424; (iii) respond as promptly as
      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
      to each Purchaser a copy of such comments and of all written responses thereto);
      (iii) any Registration Statement or any post-effective amendment is declared
      effective; (iv) the Commission or any other Federal or state governmental
      authority requests any amendment or supplement to any Registration Statement
      or
      Prospectus or requests additional information related thereto; (v) the
      Commission issues any stop order suspending the effectiveness of any
      Registration Statement or initiates any Proceedings for that purpose; (vi)
      the
      Company receives notice of any suspension of the qualification or exemption
      from
      qualification of any Registrable Securities for sale in any jurisdiction, or
      the
      initiation or threat of any Proceeding for such purpose; or (vii) the financial
      statements included in any Registration Statement become ineligible for
      inclusion therein or any statement made in any Registration Statement or
      Prospectus or any document incorporated or deemed to be incorporated therein
      by
      reference is untrue in any material respect or any revision to a Registration
      Statement, Prospectus or other document is required so that it will not contain
      any untrue statement of a material fact or omit to state any 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.

    (d)    Use
      its
      best efforts to avoid the issuance of or, if issued, obtain the withdrawal
      of
      (i) any order suspending the effectiveness of any Registration Statement, or
      (ii) any suspension of the qualification (or exemption from qualification)
      of
      any of the Registrable Securities for sale in any jurisdiction, as soon as
      possible.

     

    (e)    Furnish
      to each Purchaser and Purchaser Counsel, without charge, at least one conformed
      copy of each Registration Statement and each amendment thereto, including
      financial statements and schedules, all documents incorporated or deemed to
      be
      incorporated therein by reference, and all exhibits to the extent requested
      by
      such Person (including those previously furnished or incorporated by reference)
      promptly after the filing of such documents with the Commission.

     

    (f)    Promptly
      deliver to each Purchaser and Purchaser Counsel, without charge, as many copies
      of the Prospectus or Prospectuses (including each form of prospectus) and each
      amendment or supplement thereto as such Persons may reasonably request. The
      Company hereby consents to the use of such Prospectus and each amendment or
      supplement thereto by each of the selling Purchasers in connection with the
      offering and sale of the Registrable Securities covered by such Prospectus
      and
      any amendment or supplement thereto.

     

    (g)    (i)
      In
      the time and manner required by each Trading Market, prepare and file with
      such
      Trading Market an additional shares listing application covering all of the
      Registrable Securities; (ii) take all steps necessary to cause such Registrable
      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, within
      fifteen days after receipt of such notice, any such Purchaser shall so request
      in writing, the Company shall include in such registration statement all or
      any
      part of such Registrable Securities such Purchaser requests to be
      registered.

      VII

    MISCELLANEOUS

     

    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.

    SulphCo,
      Inc., a Nevada corporation (the “Company”),
      hereby certifies that, for value received, [Name of Holder] or its registered
      assigns (the “Holder”),
      is
      entitled to purchase from the Company up to a total of [ ]1 
      shares
      of common stock, $0.001 par value per share (the “Common
      Stock”),
      of
      the Company (each such share, a “Warrant
      Share”
and
      all
      such shares, the “Warrant
      Shares”)
      at an
      exercise price equal to $2.68 per share (as adjusted from time to time as
      provided in Section
      9,
      the
“Exercise
      Price”),
      at
      any time and from time to time from and after the date hereof and through 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
      and
      the Purchasers listed thereto (the “Purchase
      Agreement”).

        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.

     

    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

     

    
      
         

      

      
        2

        
          

        

      

      
         

      

       

      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.    Li;mitation
      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

     

    
      
         

      

      
        8

        
          

        

      

      
         

      

       

      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 the
      transactions contemplated by any of the Transaction Documents (whether brought
      against a party hereto or its respective Affiliates, directors, officers,
      shareholders, employees or agents) shall be commenced exclusively in the state
      and federal courts sitting in the City of New York, Borough of Manhattan. Each
      party hereto hereby irrevocably submits to the exclusive jurisdiction of the
      state and federal courts sitting in the City of New York, Borough of Manhattan
      for the adjudication of any dispute hereunder or in connection herewith or
      with
      any transaction contemplated hereby or discussed herein (including with respect
      to the enforcement of any of this Warrant), and hereby irrevocably waives,
      and
      agrees not to assert in any suit, action or proceeding, any claim that it is
      not
      personally subject to the jurisdiction of any such court, that such suit, action
      or proceeding is improper. Each party hereto hereby irrevocably waives personal
      service of process and consents to process being served in any such suit, action
      or proceeding by mailing a copy thereof via registered or certified mail or
      overnight delivery (with evidence of delivery) to such party at the address
      in
      effect for notices to it under this Warrant and agrees that such service shall
      constitute good and sufficient service of process and notice thereof. Nothing
      contained herein shall be deemed to limit in any way any right to serve process
      in any manner permitted by law. Each party hereto hereby irrevocably waives,
      to
      the fullest extent permitted by applicable law, any and all right to trial
      by
      jury in any legal proceeding arising out of or relating to this Warrant or
      any
      of the Transaction Documents or the transactions contemplated hereby or thereby.
      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
      attorneys fees and other reasonable costs and expenses incurred with the
      investigation, preparation and prosecution of such action or
      proceeding.

    (d)    The
      headings herein are for convenience only, do not constitute a part of this
      Warrant and shall not be deemed to limit or affect any of the provisions
      hereof.

     

    (e)    In
      case
      any one or more of the provisions of this Warrant shall be invalid or
      unenforceable in any respect, the validity and enforceability of the remaining
      terms and provisions of this Warrant shall not in any way be affected or
      impaired thereby and the parties will attempt in good faith to agree upon a
      valid and enforceable provision which shall be a commercially reasonable
      substitute therefor, and upon so agreeing, shall incorporate such substitute
      provision in this Warrant.
