        <footnote id="F1">Shares of common stock acquired as a result of the elective stock dividend paid on December 11, 2009.  Shareholders elected, pursuant to the terms of the Prospectus Supplement filed November 5, 2009 (&quot;Supplement&quot;), to receive the dividend in all or partial stock.  If all stock was elected, shareholders received their entire dividend in stock.  If partial stock was elected, shareholders received approximately $0.0575 of the $0.09 dividend in stock.  The value of the shares distributed is $7.2733 per share which were valued at the average closing price on December 1, 2, and 3, 2009 pursuant to the terms of the Supplement.</footnote>

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 due to death.</footnote>
