Ms. Benson is a member of the board of directors along with James W. Benson) and
indirect  beneficial  ownership in vested options to purchase up to an aggregate
of  1,610,000  shares  (which  may  constitute  community property with James W.
Benson).  Excluded  is approximately 1.2 million shares held by the children and

stock  owned  separately  by  James  W.  Benson  and  identified as his separate
property  asset  under  a  stipulated court order dated May 24, 2005 as to which

the  power to receive, or direct the receipt of, dividends and proceeds from the
sale  of  such shares. The 1,610,000 shares subject to options may be considered
the  community  property  of  Mr. Benson and Susan C. Benson (which may give her
certain  rights  with  respect  thereto).

         (e)  N/A.
