Consequently, if  you want us to vote your securities  on your behalf on the election of directors, you must provide voting instructions to us.

If these two requirements are metand you  have  not  communicated  to us  prior to  the first  vote  being  issued,  we may vote  your securities  at our discretion  on  any  matters  deemed   to be  routine.  We  will nevertheless follow your instructions, even if  our discretionary vote has already been given, provided your instructions are received prior to the meeting date.The following instructions  provide specifics regarding the meeting for which this voting form applies.Instruction 1All proposals for this meeting are considered "routine".  We may vote in our discretion on allproposals, if  your instructions are not received.If   your securities  are held   by  a  bank,  your  securities   cannot be  voted  without  your specific instructions.Instruction  2In order for your securities to be represented  at the meeting on one or more matters beforethe meeting, it will be necessary for us to have your specific voting instructions.If  your securities are held by a bank, your securities cannot  be voted  without your specific instructions.Instruction 3In order for your securities  to be represented  at the meeting, it will be necessary for us tohave your specific voting instructions.Instruction 4We have previously sent you proxy soliciting material  pertaining  to the  meeting of shareholdersof the company  indicated.
