               SHAREHOLDER MEETING ADJOURNED UNTIL APRIL 26, 2010

BECAUSE WE DID NOT RECEIVE SUFFICIENT SHAREHOLDER VOTES, THE SPECIAL MEETING OF
SHAREHOLDERS ORIGINALLY SCHEDULED FOR MARCH 19, 2010, HAS BEEN ADJOURNED UNTIL
APRIL 26, 2010.

OUR RECORDS SHOW THAT WE HAVE NOT YET RECEIVED YOUR VOTE ON THE PROPOSALS
PRESENTED TO SHAREHOLDERS. WE URGE YOU TO VOTE AS SOON AS POSSIBLE IN ORDER FOR
YOUR SPDR FUND(S) TO OBTAIN A SUFFICIENT NUMBER OF VOTES AND AVOID FUTURE
REMINDERS.

                 YOUR SPDR FUND'S BOARD OF TRUSTEES UNANIMOUSLY
                 RECOMMENDS THAT YOU VOTE "FOR" THE PROPOSALS.

A SHAREHOLDER MAY THINK HIS OR HER VOTE IS NOT IMPORTANT, BUT IT IS VITAL. YOUR
VOTE WILL ENABLE THE FUNDS TO HOLD THE MEETING AS SCHEDULED AND AVOID THE COST
OF ADDITIONAL SOLICITATION, SO PLEASE VOTE IMMEDIATELY.

U.S. and need assistance in voting your shares, please contact our proxy
solicitor, Broadridge Financial Solutions, Inc. at 1-877-257-9951.
