                  DIRECTORS;   APPOINTMENT  OF  CERTAIN  OFFICERS;  COMPENSATORY

         On July 25, 2008, our board of directors  resolved to increase the size
of the board from seven directors to eight, and appointed Edward F. Voboril as a
director  to fill the  vacancy  created  upon the  expansion  in the size of the
board.  Mr.  Voboril will receive an annual  retainer of $42,000,  plus a travel
stipend of $1,250 per day, for travel more than four hours, when attending board
and committee meetings.  Upon his appointment,  Mr. Voboril also received (a) an
initial award of equity compensation with a Black-Scholes value of $100,000, 25%
in the  form of  restricted  stock  and 75% in the form of  non-qualified  stock
options  with  a term  of 10  years,  which  equity  vests  in  equal  quarterly
installments  over a one year period and (b) a  pro-rated  portion of the annual
equity compensation paid to non-employee directors with a Black-Scholes value of
$91,666,  25%  in  the  form  of  restricted  stock  and  75%  in  the  form  of
non-qualified stock options with a term of 10 years, which equity vests in equal
quarterly installments over a one year period.

         Mr. Voboril previously served as the Chairman of the Board of Directors
of Greatbatch,  Inc.  (NYSE:  GB),  developer,  designer,  and  manufacturer  of
critical  components  for  implantable  medical  devices,  from  1997  until his
retirement in January 2008. Mr. Voboril also served as that company's  President
and Chief Executive Officer from 1990 to August 2006. Mr. Voboril also currently
serves as the Chairman of the Board of Analogic Corporation  (NASDAQ:  ALOG) and
serves on its audit and  nominating  and corporate  governance  committees.  Mr.
Voboril has served on Analogic's board of directors since 1990.

         Prior to his  appointment  as a member of our board of  directors,  Mr.
Voboril did not have any material  relationship with us and no such relationship
is currently proposed.  Mr. Voboril does not have any family  relationships with
any of our other directors or executive officers.

         A press release  announcing Mr. Voboril's  appointment to the Board was
issued by us on July 31,  2008,  a copy of which is  attached  hereto as Exhibit
99.1.
