As provided in the Merger Agreement, at the effective time of the Merger each outstanding Share, other than any Shares owned by Clearwater Paper or Merger Sub, by Cellu Tissue as treasury stock, or by any stockholders who are entitled to, and who properly exercise, appraisal rights under Delaware law, was converted into the right to receive $12.00 in cash without interest.
