Description of the Transaction

     On February 12, 2008, the issuer distributed in an offering registered with
the U.S. Securities and Exchange  Commission,  at no charge to record holders of
its common stock,  non-transferable subscription rights to purchase an aggregate
of  2,500,000  shares of the issuer's  common  stock.  On that date,  the issuer
distributed  0.25 of a subscription  right to its stockholders for each share of
common stock held by those  stockholders at the close of business on January 28,
2008. Each whole subscription right entitled the recipient to purchase one share
of the issuer's common stock at a subscription  price of $10.00. Any stockholder
who  exercised  his  or  her  subscription   rights  in  full  was  entitled  to
oversubscribe  for additional  shares,  subject to certain  limitations,  to the
extent shares were  available.  The  subscription  rights  expired at 5:00 p.m.,
Eastern  Time,  on March 17,  2008.  Pursuant to the rights  offering  and their
subscription rights that they exercised,  on March 24, 2008, Contran Corporation
and Annette C.  Simmons  purchased  from the issuer  1,763,434  shares and 3,457
shares, respectively, of the issuer's common stock for $10.00 per share.
