      	(c)  	
              The

                by the
                Company in connection with the preparation and filing of the Registration
                Statement and in complying with applicable securities and “blue sky” laws
                (including, without limitation, all attorneys' fees of the Company,

                expenses, escrow fees, blue sky fees and expenses, the reasonable
                fees and
                expenses of one counsel for the holders of Registrable Securities
                not to
                exceed $7,500, and the expense of any special audits incident to
                or
                required by any such registration) shall be borne by the Company.

                fees and commissions, if any, applicable to the Registrable Securities
                being registered. The Company shall not be required to qualify Registrable
                Securities in any state which will require an escrow or other restriction
                relating to the Company and/or the sellers, or which will require
                the
                Company to qualify to do business in such state. The Company at its
                expense will supply the Investor with copies of the applicable
                Registration Statement and the prospectus included therein and other
                related documents in such quantities as may be reasonably requested
                by the
                Investor.

            

    

    

    
      	(e)  	
              If
                at any time or from time to time after the Effective Date, the Company
                notifies the Investor in writing of the existence of a Potential
                Material
                Event (as defined below), the Investor shall not offer or sell any
                Registrable Securities or engage in any other transaction involving
                or
                relating to Registrable Securities, from the time of the giving of
                notice
                with respect to a Potential Material Event until the Investor receives
                written notice from the Company that such Potential Material Event
                either
                has been disclosed to the public or no longer constitutes a Potential
                Material Event.

            

    

    

    
      	(f)  	
              “Potential
                Material Event” means any of the following: (i) the possession by the
                Company of material information not ripe for disclosure in a registration
                statement, as determined in good faith by the Chief Executive Officer
                or
                the Board of Directors of the Company that disclosure of such information
                in a Registration Statement would be detrimental to the business
                and
                affairs of the Company; or (ii) any material engagement or activity
                by the
                Company which would, in the good faith determination of the Chief
                Executive Officer or the Board of Directors of the Company, be adversely
                affected by disclosure in a registration statement at such time,
                which
                determination shall be accompanied by a good faith determination
                by the
                Chief Executive Officer or the Board of Directors of the Company
                that the
                applicable Registration Statement would be materially misleading
                absent
                the inclusion of such information; provided
                that,
                (i) the Company shall not use such right with respect to the Registration
                Statement for more than an aggregate of 60 days in any 12-month period;
                and (ii) the number of days the Company is required to keep the
                Registration Statement effective shall be extended by the number
                of days
                for which the Company shall have used such
                right.

      	(g)  	
              The
                Investor will cooperate with the Company in all respects in connection
                with this Agreement, including timely supplying all information reasonably
                requested by the Company (which shall include all information regarding
                the Investor and proposed manner of sale of the Registrable Securities
                required to be disclosed in any Registration Statement) and executing
                and
                returning all documents reasonably requested in connection with the
                registration and sale of the Registrable Securities. Any delay or
                delays
                caused by the Investor, or by any other purchaser of securities of
                the
                Company having registration rights similar to those contained herein,
                by
                failure to cooperate as required hereunder shall not constitute a
                breach
                or default of the Company under this Agreement.

            

    

    

    
      	(h)  	
              Whenever
                the Company is required by any of the provisions of this Agreement
                to
                effect the registration of any of the Registrable Securities under
                the
                Act, the Company shall (except as otherwise provided in this Agreement),
                as expeditiously as possible, subject to the assistance and cooperation
                as
                reasonably required of the Investor with respect to each Registration
                Statement:

            

    

    

    
      	 	
              (i)

            	
              register
                and qualify the Registrable Securities covered by the Registration
                Statement under such other securities or blue sky laws of such
                jurisdictions as the Investor shall reasonably request (subject to
                the
                limitations set forth in Section 1(d) above), and do any and all
                other
                acts and things which may be necessary or advisable to enable the
                Investor
                to consummate the public sale or other disposition in such jurisdiction
                of
                the securities owned by the
                Investor;

            

    

    

    
      	 	
              (ii)

            	
              cause
                the Registrable Securities to be, and continue to be, quoted or listed
                on
                the National Association of Securities Dealers over the counter bulletin
                board (or alternatively, a national securities exchange or automated
                quotation system); 

            

    

    

    
      	 	
              (iii)

            	
              notify
                the Investor, at any time when a prospectus relating thereto covered
                by
                the Registration Statement is required to be delivered under the
                Act, of
                the happening of any event of which it has knowledge as a result
                of which
                the prospectus included in the Registration Statement, as then in
                effect,
                includes an untrue statement of a material fact or omits to state
                a
                material fact required to be stated therein or necessary to make
                the
                statements therein not misleading in the light of the circumstances
                then
                existing, and the Company shall prepare and file a curative amendment
                as
                promptly as commercially reasonable;

              (iv)

            	
              as
                promptly as practicable after becoming aware of such event, notify
                the
                Investor, (or, in the event of an underwritten offering, the managing
                underwriters) of the issuance by the SEC of any stop order or other
                suspension of the effectiveness of the Registration Statement at
                the
                earliest possible time and take all lawful action to effect the
                withdrawal, recession or removal of such stop order or other suspension;
                and

            

    

    

    
      	 	
              (v)

            	
              provide
                a transfer agent and registrar for all securities registered pursuant
                to
                the Registration Statement and a CUSIP number for all such
                securities.

            

    

    

    
      	 	
              (i)

            	
              With
                respect to any sale of Registrable Securities pursuant to a Registration
                Statement filed pursuant to this Section 1, the Investor hereby covenants
                with the Company not to make any sale of the Registrable Securities
                without effectively causing the prospectus delivery requirements
                under the
                Act to be satisfied.

            

    

    

    
      	 	
              (j)

            	
              In
                addition to the registration rights set forth in Section 1(b), if
                the
                Second Offering does not occur or is not completed or if the Registration
                Statement described in Section 1(b) is not filed within 60 calendar
                days
                from the final Closing of the Second Offering, or otherwise declared
                effective by the SEC, then the Investors shall also have certain
                “piggyback” registration rights as
                follows:

            

    

    

    
      	(i)  	
              If
                at any time after the issuance of the Registrable Securities, the
                Company
                shall file with the SEC a registration statement under the Act registering
                any shares of equity securities and which could also include for
                registration the Registrable Securities without additional undue
                expense
                in the reasonable discretion of the Company, the Company shall give
                written notice to each Investor prior to such
                filing.

            

    

    

    
      	(ii)  	
              Within
                20 calendar days after such notice from the Company, each Investor
                shall
                give written notice to the Company whether or not such Investor desires
                to
                have all of such Investor’s Registrable Securities included in the
                registration statement. If any Investor fails to give such notice
                within
                such period, such Investor shall not have the right to have Investor’s
                Registrable Securities registered pursuant to such registration statement.
                If any Investor gives such notice, then the Company shall include
                such
                Investor’s Registrable Securities in the registration statement, at
                Company’s sole cost and expense, subject to the remaining terms of this
                Section 1(j).

            

    

     

    
      
        
        

      

      
        4

        
          

        

      

      
        
        

      

    

     

    
      	(iii)  	
              If
                the registration statement relates to an underwritten offering, and
                the
                underwriter shall determine in writing that the total number of shares
                of
                equity securities to be included in the offering, including the
                Registrable Securities, shall exceed the amount which the underwriter
                deems to be appropriate for the offering, the number of shares of
                the
                Registrable Securities shall be reduced in the same proportion as
                the
                remainder of the shares in the offering and such participating Investor’s
                Registrable Securities included in such registration statement will
                be
                reduced proportionately. For this purpose, if other securities in
                the
                registration statement are derivative securities, their underlying
                shares
                shall be included in the computation. Each participating Investor
                shall
                enter into such agreements as may be reasonably required by the
                underwriters and each Investor shall pay the underwriters commissions
                relating to the sale of their respective Registrable
                Securities.

            

    

    

    
      	(iv)  	
              The
                Investors shall have an unlimited number of opportunities to have
                the
                Registrable Securities registered under this Section 1(j) provided
                that
                the Company shall not be required to register any Registrable Security
                or
                keep any Registration Statement effective beyond such period set
                forth in
                Section 1(c).

            

    

    

    
      	(v)  	
              The
                Investor shall furnish in writing to the Company such information
                as the
                Company shall reasonably require in connection with a registration
                statement.

            

    

    

    
      	 	
              (k)

            	
              The
                Company acknowledges that there is no adequate remedy at law for
                failure
                by it to comply with the provisions of Section 1 of this Agreement
                and
                that such failure would not be adequately compensable in damages,
                and
                therefore agrees that its agreements contained in such Section 1
                may be
                specifically enforced. In the event that the Registration Statement
                to be
                filed by the Company pursuant to Section 1(b) above is not filed
                with the
                SEC within 60 days from the final Closing Date of the Second Offering
                (the
                “Registration Default”), then for every 30 day period or increment there
                of that the Company is late in filing the Registration Statement,
                the
                Company shall issue to the Investor, as liquidated damages for such
                failure and not as a penalty, additional Common Shares in whole share
                increments equal to 1% of the Common Shares purchased by the Investor
                in
                the Offering until such Registration Statement has been filed. Such
                issuance of Common Shares as liquidated damages shall be made to
                the
                Investor within five calendar days of demand, provided,
                however,
                that the issuance of Common Shares as liquidated damages shall not
                relieve
                the Company from its obligations to register the Registrable Securities
                pursuant to this Agreement. Notwithstanding anything to the contrary
                contained herein, a failure of the Registration Statement to be declared
                effective, to maintain the effectiveness of a filed Registration
                Statement
                or the ability of an Investor to use an otherwise effective Registration
                Statement to effect resales of Securities shall not constitute a
                Registration Default and shall not trigger the accrual of liquidated
                damages hereunder.

              If
                the Company does not pay the amount due as liquidated damages to
                the
                Investor as set forth above, the Company will pay the Investor’s
                reasonable costs of collection, including attorneys’ fees, in addition to
                the liquidated damages. The registration of the Registrable Securities
                pursuant to this provision shall not affect or limit the Investor’s other
                rights or remedies as set forth in this
                Agreement.

            

    

    

    2. Indemnity
      and Contribution

    

    
      	(a)  	
              The
                Company agrees to indemnify and hold harmless the Investor, its officers,
                directors, employees, partners, legal counsel and accountants, and
                each
                person controlling such Investor within the meaning of Section 15
                of the
                Act, and each person who controls any underwriter within the meaning
                of
                Section 15 of the Act, from and against any losses, claims, damages,
                expenses or liabilities (or actions or proceedings in respect thereof)
                to
                which such Investor or such other indemnified person may become subject
                (including in settlement of litigation, whether commenced or threatened)
                insofar as such losses, claims, damages, expenses or liabilities
                (or
                actions or proceedings in respect thereof) arise out of, or are based
                upon, any untrue statement or alleged untrue statement of a material
                fact
                or omission or alleged omission to state a material fact in the
                Registration Statement, including all documents filed as a part thereof
                and information deemed to be a part thereof, on the effective date
                thereof, or any amendment or supplements thereto, or arise out of
                any
                failure by the Company to fulfill any undertaking or covenant included
                in
                the Registration Statement or to perform its obligations hereunder
                or
                under applicable law and the Company will, as incurred, reimburse
                such
                Investor, each of its respective officers, directors, employees,
                partners,
                legal counsel and accountants, and each person controlling such Investor,
                and each person who controls any such underwriter, for any legal
                or other
                expenses reasonably incurred in investigating, defending or preparing
                to
                defend, settling, compromising or paying such action, proceeding
                or claim;
                provided,
                however,
                that the Company shall not be liable in any such case to the extent
                that
                such loss, claim, damage, expense or liability (or action or proceeding
                in
                respect thereof) arises out of, or is based upon, (i) the failure
                of any
                Investor, or any of their agents, affiliates or persons acting on
                their
                behalf, to comply with the covenants and agreements contained in
                this
                Agreement with respect to the sale of Registrable Securities, (ii)
                an
                untrue statement or omission in such Registration Statement in reliance
                upon and in conformity with written information furnished to the
                Company
                by an instrument duly executed by or on behalf of the Investor, or
                any of
                its agents, affiliates or persons acting on its behalf, and stated
                to be
                specifically for use in preparation of the Registration Statement
                and not
                corrected in a timely manner by the Investor in writing or (iii)
                an untrue
                statement or omission in any prospectus that is corrected in any
                subsequent prospectus, or supplement or amendment thereto, that was
                delivered to the Investor prior to the pertinent sale or sales by
                such
                Investor and not delivered by the Investor to the individual or entity
                to
                which it made such sale(s) prior to such
                sale(s).

      	(b)  	
              The
                Investor agrees to indemnify and hold harmless the Company from and
                against any losses, claims, damages, expenses or liabilities (or
                actions
                or proceedings in respect thereof) to which the Company may become
                subject
                (under the Act or otherwise) insofar as such losses, claims, damages,
                expenses or liabilities (or actions or proceedings in respect thereof)
                arise out of, or are based upon (i) the failure of the Investor or
                any of
                its agents, affiliates or persons acting on its behalf, to comply
                with the
                covenants and agreements contained in this Agreement with respect
                to the
                sale of Registrable Securities; or (ii) an untrue statement or alleged
                untrue statement of a material fact or omission to state a material
                fact
                in the Registration Statement in reliance upon and in conformity
                with
                written information furnished to the Company by an instrument duly
                executed by or on behalf of such Investor and stated to be specifically
                for use in preparation of the Registration Statement; provided,
                however,
                that the Investor shall not be liable in any such case for (i) any
                untrue
                statement or alleged untrue statement or omission in any prospectus
                or
                Registration Statement which statement has been corrected, in writing,
                by
                such Investor and delivered to the Company before the sale from which
                such
                loss occurred; or (ii) an untrue statement or omission in any prospectus
                that is corrected in any subsequent prospectus, or supplement or
                amendment
                thereto, that was delivered to the Investor prior to the pertinent
                sale or
                sales by the Investor and delivered by the Investor to the individual
                or
                entity to which it made such sale(s) prior to such sale(s), and the
                Investor, severally and not jointly, will, as incurred, reimburse
                the
                Company for any legal or other expenses reasonably incurred in
                investigating, defending or preparing to defend any such action,
                proceeding or claim. Notwithstanding the foregoing, the Investor
                shall not
                be liable or required to indemnify the Company in the aggregate for
                any
                amount in excess of the net amount received by the Investor from
                the sale
                of the Registrable Securities, to which such loss, claim, damage,
                expense
                or liability (or action proceeding in respect thereof)
                relates.

            

    

    

    
      	(c)  	
              Promptly
                after receipt by any indemnified person of a notice of a claim or
                the
                beginning of any action in respect of which indemnity is to be sought
                against an indemnifying person pursuant to this Section 2, such
                indemnified person shall notify the indemnifying person in writing
                of such
                claim or of the commencement of such action and, subject to the provisions
                hereinafter stated, in case any such action shall be brought against
                an
                indemnified person, the indemnifying person shall be entitled to
                participate therein, and, to the extent that it shall wish, to assume
                the
                defense thereof. After notice from the indemnifying person to such
                indemnified person of the indemnifying person’s election to assume the
                defense thereof, the indemnifying person shall not be liable to such
                indemnified person for any legal expenses subsequently incurred by
                such
                indemnified person in connection with the defense thereof; provided,
                however,
                that if there exists or shall exist a conflict of interest that would,
                in
                the opinion of counsel to the indemnified party, make it inappropriate
                under applicable laws or codes of professional responsibility for
                the same
                counsel to represent both the indemnified person and such indemnifying
                person or any affiliate or associate thereof, the indemnified person
                shall
                be entitled to retain its own counsel at the expense of such indemnifying
                person; provided,
                further,
                that the indemnifying person shall not be obligated to assume the
                expenses
                of more than one counsel to represent all indemnified persons. In
                the
                event of such separate counsel, such counsel shall agree to reasonably
                cooperate.

      	(d)  	
              If
                the indemnification provided for in this Section 2 is unavailable
                or
                insufficient to hold harmless an indemnified party under subsection
                (a) or
                (b) above in respect of any losses, claims, damages, expenses or
                liabilities (or actions or proceedings in respect thereof) referred
                to
                therein, then each indemnifying party shall contribute to the amount
                paid
                or payable by such indemnified party as a result of such losses,
                claims,
                damages, expenses or liabilities (or actions or proceedings in respect
                thereof) in such proportion as is appropriate to reflect the relative
                fault of the Company on the one hand and the Investor, or its agents,
                affiliates or persons acting on its behalf, on the other in connection
                with the statements or omissions which resulted in such losses, claims,
                damages, expenses or liabilities (or actions or proceedings in respect
                thereof), as well as any other relevant equitable considerations.
                The
                relative fault shall be determined by reference to, among other things,
                whether the untrue or alleged untrue statement of a material fact
                or the
                omission or alleged omission to state a material fact relates to
                information supplied by the Company on the one hand or the Investor,
                or
                its agents, affiliates or persons acting on its behalf, on the other
                and
                the parties’ relative intent, knowledge, access to information and
                opportunity to correct or prevent such statement or omission. The
                Company
                and the Investor agree that it would not be just and equitable if
                contribution pursuant to this subsection (d) were determined by any
                other
                method of allocation which does not take into account the equitable
                considerations referred to above in this subsection (d). The amount
                paid
                or payable by an indemnified party as a result of the losses, claims,
                damages, expenses or liabilities (or actions or proceedings in respect
                thereof) referred to above in this subsection (d) shall be deemed
                to
                include any legal or other expenses reasonably incurred by such
                indemnified party in connection with investigating or defending any
                such
                action or claim. No person guilty of fraudulent misrepresentation
                (within
                the meaning of Section 11(f) of the Act) shall be entitled to contribution
                from any person who was not guilty of such fraudulent misrepresentation.
                In any event, the Investor shall not be liable or required to contribute
                to the Company in the aggregate for any amount in excess of the net
                amount
                received by the Investor from the sale of its Registrable
                Securities.

              Severability.
                The provisions of this Agreement are severable, so that the invalidity
                or
                unenforceability of any provision of this Agreement shall not affect
                the
                validity or enforceability of any other term or provision of this

    1. Exercise
      of Warrant.
      

    

    1.1. Number
      of Shares Issuable upon Exercise.
      From
      and after the date hereof through and including the Expiration Date, the Holder
      shall be entitled to receive, upon exercise of this Warrant in whole or in
      part,
      shares of Common Stock of the Company, subject to adjustment pursuant to Section
      4, by delivery of an original or fax copy of the exercise notice attached hereto
      as Exhibit A (the “Exercise Notice”) along with payment to the Company of the
      Exercise Price.

    

    2.
       Procedure
      for Exercise.

    

    2.1 Delivery
      of Stock Certificates, etc. on Exercise.
      The
      Company agrees that the shares of Common Stock purchased upon exercise of this
      Warrant shall be deemed to be issued to the Holder as the record owner of such
      shares as of the close of business on the date on which both the Exercise Notice
      and payment have been made for such shares. As soon as practicable after the
      exercise of this Warrant in full or in part, and in any event within five
      business days thereafter, the Company at its expense (including the payment
      by
      it of any applicable issue taxes) will cause to be issued in the name of and
      delivered to the Holder, or as such Holder (upon payment by such holder of
      any
      applicable transfer taxes) may direct in compliance with applicable securities
      laws, a certificate or certificates for the number of duly and validly issued,
      fully paid and nonassessable shares of Common Stock (or Other Securities) to
      which such Holder shall be entitled on such exercise. 

     

    2.2. Exercise.

    

    Payment
      may be made either in cash or by certified or official bank check payable to
      the
      order of the Company equal to the applicable aggregate Exercise Price for the
      number of shares of Common Stock specified in the Exercise Notice (as such
      exercise number shall be adjusted to reflect any adjustment in the total number
      of shares of Common Stock issuable to the Holder per the terms of this Warrant)
      and the Holder shall thereupon be entitled to receive the number of duly
      authorized, validly issued, fully-paid and non-assessable shares of Common
      Stock
      (or Other Securities) determined as provided herein.

     

    
      
        
        

      

      
        2

        
          

        

      

      
        
        

      

    

     

    3. Adjustment
      for Reorganization, Consolidation, Merger, etc.

    

    3.1. Reorganization,
      Consolidation, Merger, etc.
      In case
      at any time or from time to time, the Company shall (a) effect a reorganization,
      (b) consolidate with or merge into any other person or entity, or (c) transfer
      all or substantially all of its properties or assets to any other person or
      entity under any plan or arrangement contemplating the dissolution of the
      Company, then, in each such case, as a condition to the consummation of such
      a
      transaction, proper and adequate provision shall be made by the Company whereby
      the Holder of this Warrant, on the exercise hereof as provided in Section 1
      at
      any time after the consummation of such reorganization, consolidation or merger
      or the effective date of such dissolution, as the case may be, shall receive,
      in
      lieu of the Common Stock (or Other Securities) issuable on such exercise prior
      to such consummation or such effective date, the stock and other securities
      and
      property (including cash) to which such Holder would have been entitled upon
      such consummation or in connection with such dissolution, as the case may be,
      if
      such Holder had so exercised this Warrant, immediately prior thereto, all
      subject to further adjustment thereafter as provided in Section 4.

    

    3.2. Dissolution.
      In the
      event of any dissolution of the Company following the transfer of all or
      substantially all of its properties or assets, the Company, prior to such
      dissolution, shall at its expense deliver or cause to be delivered the stock
      and
      other securities and property (including cash, where applicable) receivable
      by
      the Holder of the Warrant after the effective date of such dissolution pursuant
      to Section 3.1 to a bank or trust company as trustee for the Holder of the
      Warrant. 

    

    3.3. Continuation
      of Terms.
      Upon
      any reorganization, consolidation, merger or transfer (and any dissolution
      following any transfer) referred to in this Section 3, this Warrant shall
      continue in full force and effect and the terms hereof shall be applicable
      to
      the shares of stock and other securities and property receivable on the exercise
      of this Warrant after the consummation of such reorganization, consolidation
      or
      merger or the effective date of dissolution following any such transfer, as
      the
      case may be, and shall be binding upon the issuer of any such stock or other
      securities, including, in the case of any such transfer, the person acquiring
      all or substantially all of the properties or assets of the Company, whether
      or
      not such person shall have expressly assumed the terms of this Warrant as
      provided in Section 4. In the event this Warrant does not continue in full
      force
      and effect after the consummation of the transactions described in this Section
      3, then only in such event will the Company's securities and property (including
      cash, where applicable) receivable by the Holder of the Warrant be delivered
      to
      a trustee as contemplated by Section 3.2.

    

    4. Adjustments
      for Stock Splits, Combinations, etc.
      In the
      event that the Company shall (a) issue additional shares of the Common Stock
      as
      a dividend or other distribution on outstanding Common Stock, (b) subdivide
      its
      outstanding shares of Common Stock, or (c) combine its outstanding shares of
      the
      Common Stock into a smaller number of shares of the Common Stock, then, in
      each
      such event, the Exercise Price shall, simultaneously with the happening of
      such
      event, be adjusted by multiplying the then Exercise Price by a fraction, the
      numerator of which shall be the number of shares of Common Stock outstanding
      immediately prior to such event and the denominator of which shall be the number
      of shares of Common Stock outstanding immediately after such event, and the
      product so obtained shall thereafter be the Exercise Price then in effect.
      The
      Exercise Price, as so adjusted, shall be readjusted in the same manner upon
      the
      happening of any successive event or events described herein in this Section
      4.
      The number of shares of Common Stock that the Holder of this Warrant shall
      thereafter, on the exercise hereof as provided in Section 1, be entitled to
      receive shall be increased to a number determined by multiplying the number
      of
      shares of Common Stock that would otherwise (but for the provisions of this
      Section 4) be issuable on such exercise by a fraction of which (a) the numerator
      is the Exercise Price that would otherwise (but for the provisions of this
      Section 4) be in effect, and (b) the denominator is the Exercise Price in effect
      on the date of such exercise.

    5. Certificate
      as to Adjustments.
      In each
      case of any adjustment or readjustment in the shares of Common Stock (or Other
      Securities) issuable on the exercise of the Warrant, the Company at its expense
      will promptly cause its Chief Financial Officer or other appropriate designee
      to
      compute such adjustment or readjustment in accordance with the terms of the
      Warrant and prepare a certificate setting forth such adjustment or readjustment
      and showing in detail the facts upon which such adjustment or readjustment
      is
      based, including a statement of (a) the consideration received or receivable
      by
      the Company for any additional shares of Common Stock (or Other Securities)
      issued or sold or deemed to have been issued or sold, (b) the number of shares
      of Common Stock (or Other Securities) outstanding or deemed to be outstanding,
      and (c) the Exercise Price and the number of shares of Common Stock to be
      received upon exercise of this Warrant, in effect immediately prior to such
      adjustment or readjustment and as adjusted or readjusted as provided in this
      Warrant. The Company will forthwith mail a copy of each such certificate to

    13. Miscellaneous.
      This
      Warrant and any term hereof may be changed, waived, discharged or terminated
      only by an instrument in writing signed by the party against which enforcement
      of such change, waiver, discharge or termination is sought. This Warrant shall
      be governed by and construed in accordance with the laws of State of California
      without regard to principles of conflicts of laws. Any action brought concerning
      the transactions contemplated by this Warrant shall be brought only in the
      state
      courts of California or in the federal courts located in the state of
      California. The individuals executing this Warrant on behalf of the Company
      agree to submit to the jurisdiction of such courts and waive trial by jury.
      The
      prevailing party shall be entitled to recover from the other party its
      reasonable attorney’s fees and costs. In the event that any provision of this
      Warrant is invalid or unenforceable under any applicable statute or rule of
      law,
      then such provision shall be deemed inoperative to the extent that it may
      conflict therewith and shall be deemed modified to conform with such statute
      or
      rule of law. Any such provision which may prove invalid or unenforceable under
      any law shall not affect the validity or enforceability of any other provision
      of this Warrant. The headings in this Warrant are for purposes of reference
      only, and shall not limit or otherwise affect any of the terms hereof. The
      invalidity or unenforceability of any provision hereof shall in no way affect
      the validity or enforceability of any other provision. The Company acknowledges
      that legal counsel participated in the preparation of this Warrant and,
      therefore, stipulates that the rule of construction that ambiguities are to
      be
      resolved against the drafting party shall not be applied in the interpretation
      of this Warrant to favor any party against the other party.
