The foregoing shareholders are solely responsible for the content of their Position Statement. The Board rejects any and all assertions in this Position Statement and stands by its recommendations as set forth in the Proxy Statement, and in the Supplement (which includes the Board’s statement in opposition to the original Proposing Shareholders’ proposal and the Board’s recommendation to vote AGAINST such proposal), both of which are available at the SEC’s website at https://www.sec.gov/Archives/edgar/data/1365767/000117891317000949/0001178913-17-000949-index.htm ; and at  https://www.sec.gov/Archives/edgar/data/1365767/000117891317001114/0001178913-17-001114-index.htm, respectively.
