                                        name as written upon the face of

IMPORTANT NOTICE: When you sign your name to this Assignment Form without 
filling in the name of your "Assignee" or "Attorney", this stock certificate 
becomes fully negotiable, similar to a check endorsed in blank. Therefore, to 
safeguard a signed certificate, it is recommended that you either (i) fill in 
the name of the new owner in the "Assignee" blank, or (ii) if you are sending 
the signed certificate to your bank or broker, fill in the name of the bank 
or broker in the "Attorney" blank. Alternatively, instead of using this 
Assignment Form, you may sign a separate "stock power" form and then mail the 
unsigned stock certificate and the signed "stock power" in separate 
envelopes. For added protection, use certified or registered mail for a stock 
certificate.
