                 IMPORTANT NOTICE IMMEDIATE ATTENTION REQUESTED
                 YOUR PROMPT VOTE IS CRITICAL TO THE SPDR FUNDS

Dear SPDR Fund(s) Shareholder,

     The SPDR Funds recently contacted you regarding a Special Meeting of
Shareholders (the "Meeting") for your vote on proposals for the SPDR Funds. Due
to a lack of sufficient shareholder votes, the Meeting has been adjourned for a
second time to May 20, 2010, at 11:00 AM (EST) with regard to your SPDR Fund(s).

     After repeated attempts, we still have not yet received your vote. The
reason we have been contacting you is that Shareholder action is required to
approve the proposals for each of the SPDR Funds. The Fund(s) will be materially
impacted without your vote.

     The Board of Directors/Trustees of the SPDR Funds has unanimously
recommended that shareholders vote in favor of the proposals. If we do not have
a sufficient number of votes to hold the Meeting, the Board of
Directors/Trustees of the SPDR Funds will take such action it deems necessary
and in the best interests of those SPDR Funds and their shareholders. We urge
you to vote today without further delay.

     To vote your shares, please call 1-877-257-9951. Representatives are
available Monday through Friday 9:30 AM to 9:00 PM (EST), and Saturday from
10:00 AM to 6:00 PM (EST). You may also vote by mail, automated telephone, or
internet, as further detailed on the enclosed proxy card.

     ON BEHALF OF THE BOARD OF DIRECTORS/TRUSTEES OF THE SPDR FUNDS, PLEASE
ACCEPT MY THANKS FOR YOUR PARTICIPATION IN THIS IMPORTANT MATTER.

                                        Sincerely,


                                        /s/ Jim Ross

                                        President
