Item
      1.01. Entry into a Material Definitive Agreement.
On
      May
      31, 2006, Sand Hill IT Security Acquisition Corp. (the "Company") entered into a
      Second Amendment (the "Second Amendment") to the Agreement and Plan of Merger
by
      and
      among the Company, its wholly-owned subsidiary Sand Hill Merger Corp., a
      Delaware corporation ("Merger Sub")
and
      St. Bernard
Software, Inc.
,
      a
      Delaware corporation
("St. Bernard"),
      dated October 26, 2005, as amended by that certain First Amendment to Merger
      Agreement, dated December 15, 2005 (the "Merger Agreement"). Pursuant to the
      terms of the Second Amendment,
1,700,000
      of the shares of Company common stock to be initially issued in connection
      with
      the merger will be issued to a stockholders' representative that will hold these
      shares on behalf of the persons who held shares of St. Bernard common stock
      as
      of the closing of the merger. These shares will be released, pro rata, to the
      persons who held shares of St. Bernard common stock as of the closing of the
      merger, if, after the merger, the price of the combined company's common stock
      closes at $8.50 or more per share for 20 trading days during any 30-day trading
      period prior to July 25, 2009 or the consideration to be received by the
      combined company or its stockholders in a sale of the majority of the ownership
      or business of the combined company prior to July 25, 2009 equals or
      exceeds $8.50 per share, excluding the dilutive effects of the exercise of
      any
      of the warrants issued by the Company in its initial public offering. If, after
      the merger, neither of these thresholds are achieved prior to July 25, 2009,
      then the 1,700,000 shares will be returned to the combined company for no
      consideration and will be cancelled.
