                    VOTING INSTRUCTIONS FOR ALL STOCKHOLDERS

There are three convenient ways to vote your proxy.

     1-             , 7 days a week, 24 hours a day. Have your proxy card in
     hand when you call. You will be prompted to enter your control number,
     located in the box below, and then follow the simple directions, OR

o    VOTE BY INTERNET: Use the internet to vote your proxy. Log on to the
     website http://         . Have your proxy card in hand when you access the
     website. You will be prompted to enter your control number, located in the
     box below, to create an electronic proxy, OR

o    VOTE BY MAIL: Mark, sign and date your proxy card and return it in the
     postage-paid envelope we have provided.

Delaware General Corporation Law authorizes the use of electronic transmission,
such as transmissions over the internet, to grant a proxy.
