These shares will vest 25% per year on each anniversary date of the grant as previously disclosed, and CPI will hold these shares until such shares become vested.  While the shares are being held prior to vesting, the reporting person will have the right to receive all cash dividends and to vote the restricted shares.  All unvested shares will forfeit if the Director's service as a member of the CPI Board of Directors terminates, unless separation is due to death.</footnote>
