      Approval. The Plan was adopted by the
      Board on May 13, 2010 and approved by the Company’s shareholders on May
      13, 2010. The Plan was amended and restated by the Board on February 2,

      with respect to such additional shares prior to such shareholder approval

      shall terminate on that date. 

                   
      (b) Termination of Plan. Unless sooner terminated by the Board or pursuant to
      paragraph (a) above, the provisions of the Plan respecting the grant of
      any award pursuant to which shares of Common Stock will be granted shall
      terminate (i) with respect to the initial 2,000,000 shares authorized for
      issuance under the Plan, on May 13, 2020, the tenth anniversary of the
      date of the Plan’s adoption by the Board and (ii) with respect to the
      additional 2,500,000 shares subsequently authorized under the Plan, on the
      tenth anniversary of the date of the Board’s adoption of the amendment to
      the Plan authorizing the issuance of such shares. All awards made under
      the Plan prior to the termination of the Plan shall remain in effect until
      such awards have been satisfied or terminated in accordance with the terms
      and provisions of the Plan and the applicable award certificates.
