      to
      transfer the Shares, free and clear of all liens, claims, charges and other
      encumbrances.

    


    (b) Stockholder
      has full right, power and authority to enter into this Agreement and to transfer
      the Shares in accordance with the terms of this Agreement, and this Agreement
      constitutes a legal, valid and binding obligation of Stockholder.

    


    (c) Stockholder
      has not assigned or transferred any interest in any of the Shares, or entered
      into any agreement the effect of which is to modify the rights of the holder
      of
      the Shares.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    (d) Stockholder
      acknowledges and represents that the Company is not a fiduciary of Stockholder
      and that Stockholder and the Company have entered into the transactions that
      are
      the subject of this Agreement at arms' length.

    


    (e) Stockholder
      is not currently acting as an agent of the Company, or as an underwriter or
      a

      participated in the Offering.

    


    (f) Stockholder
      has not offered or sold any shares of capital stock of the Company by any form
      of general solicitation or general advertising.

    


    (g) Stockholder
      is relying on his business or financial experience or the business or financial
      experience of Stockholder’s professional advisors who are unaffiliated with the
      Company, in determining whether to enter into this Agreement and to transfer
      the
      Shares to the Company pursuant to the Company.

    


    (h) Stockholder
      is an “accredited investor” as defined in Rule 501(a) under the Securities
      Act.

    


    (i) The
      Company has made it’s officers and directors available to Stockholder to answer
      questions about the Company and its business. Stockholder has conducted his
      own
      investigation, to the extent that the Stockholder has determined necessary
      or
      desirable, regarding the Company and Stockholder has not relied upon any
      statements or representations made by the Company or any director, officer,
      employee, representative or other advisor of the Company in making its decision
      to sell the Shares. Stockholder acknowledges that the Company or its officers,
      directors, employees or affiliates may be in possession of material, nonpublic
      information regarding the Company. Stockholder agrees to sell the Shares to
      the
      Company pursuant to the terms hereof without access to such information.
      Stockholder acknowledges and agrees that no representations or warranties,
      whether express or implied, were, or are being, given to Stockholder by the
      Company, other than the representations and warranties as are set forth in

    (j) Stockholder
      has reviewed with its own tax and legal advisors the tax and legal consequences
      of the transactions contemplated by this Agreement. Stockholder relies solely
      on
      such advisors and not on any statements or representations of or of any of
      the
      Company’s agents with respect to such tax and legal consequences. Stockholder
      understands that Stockholder, and not the Company, shall be responsible for
      Stockholder’s own tax and legal liability that may arise as a result of the
      transactions contemplated by this Agreement.

    


    (k) Stockholder
      acknowledges that no representation by the Company is made that the Purchase
      Price it is to receive for sale of the Shares under this Agreement is fair
      to
      the Stockholder or equal to any purchase price that may be offered to other
      parties, now or in the future, and that such Purchase Price may be greater
      or
      less than the actual fair market value of the Shares. Stockholder acknowledges
      that shares of the Company’s common stock may trade at prices higher than the
      Purchase Price and that the Company may offer its shares, or other stockholders
      of the Company may in the future sell their shares to the Company or to third
      parties, at prices higher or lower than the Purchase Price. Stockholder
      acknowledges that it will have no future participation in any Company gains,
      profits or dividends with respect to the Shares. Stockholder acknowledges that
      the Company and its Board of Directors have expressed no opinion to Stockholder
      and made no recommendation to Stockholder as to whether Stockholder should
      sell
      the Shares to the Company pursuant to the terms of this Agreement and that
      the
      Company’s Board of Directors has told Stockholder that it did not request, and
      did not receive, a fairness opinion from any financial advisor with respect
      to
      the purchase price for the Shares.

      shall
      notify the party from whom such indemnification is sought (the "Indemnifying
      Party")
      in
      writing of the Proceeding and the facts constituting the basis for such claim
      in
      reasonable detail. The Indemnifying Party shall have the right, exercisable
      by
      giving written notice to an Indemnified Party after receipt of written notice
      from such Indemnified Party of such Proceeding, to assume, at the Indemnifying
      Party's expense, the defense of any such Proceeding, with counsel reasonably
      satisfactory to such Indemnified Party. The Indemnified Party shall have the
      right to retain the counsel of its choice in connection with such Proceeding
      and
      to participate at its own expense in the defense of any such Proceeding;
provided,
      however,
      that
      counsel to the Indemnifying Party shall not (except with the consent of the
      relevant Indemnified Party) also be counsel to such Indemnified Party. In no
      event shall the Indemnifying Party be liable for fees and expenses of counsel
      (in addition to any local counsel) other than its own counsel for all
      Indemnified Parties in connection with any one action or separate but similar
      or
      related actions in the same jurisdiction arising out of the same general
      allegations or circumstances. No Indemnifying Party shall, without the prior
      written consent of the Indemnified Parties (which consent shall not be
      unreasonably withheld), settle or compromise or consent to the entry of any
      judgment with respect to any litigation, or any investigation or proceeding
      by
      any governmental agency or body, commenced or threatened, or any claim
      whatsoever in respect of which indemnification could be sought under this
      Section 5 unless such settlement, compromise or consent (A) includes an
      unconditional release of each Indemnified Party from all liability arising
      out
      of such litigation, investigation, proceeding or claim and (B) does not include
      a statement as to or an admission of fault, culpability or a failure to act
      by
      or on behalf of any Indemnified Party.
