| Q. | Will               
 anyone contact me? |

| A. | You                                                                                     
 may receive a call from Computershare Fund Services, the proxy solicitor hired by your  
 Fund, to verify that you received your proxy materials, to answer any questions you may 
 have about the Mergers or the other proposal and to encourage you to vote your proxy.   |

We recognize the inconvenience of the proxy solicitation process and would not impose on you if we did not believe that the matter being proposed was important. Once your vote has been registered with the proxy solicitor, your name will be removed from the solicitor’s follow-up contact list.

Your vote is very important. We encourage you as a shareholder to participate in your Fund’s governance by returning your vote as soon as possible. If enough shareholders fail to cast their votes, a Fund may not be able to hold its Meeting or the vote on the Merger or other proposal and will be required to incur additional solicitation costs in order to obtain sufficient shareholder participation.
