PLEASE VOTE NOW

VOTING NOW HELPS THE FUND LOWER OVERALL PROXY COSTS AND ELIMINATES PHONE CALLS

Time is running short and the Special Meeting is rapidly approaching. According to our records your vote has not yet been received. To avoid adjournments and additional solicitation costs, your Board of Directors is asking you to use the enclosed proxy card to authorize your proxy “FOR” the approval of an agreement and plan of reorganization calling for the merger of your Fund into the DWS RREEF Global Real Estate Securities Fund, an open-end investment company. We hope you will take this opportunity to vote your shares ”FOR” the proposal.

The Board of Directors of the Fund recommends

that you vote “FOR” the proposal.

Your vote is important, no matter how large or small your holdings may be. We urge you to vote “FOR” the proposal by completing, signing and dating the enclosed proxy card and promptly mailing it in the enclosed postage-paid envelope. Alternatively, you may vote by calling 1-800-454-8683 or via the internet at www.proxyvote.com and following the instructions on the enclosed card. A failure to vote has the effect of a vote against the merger.

If you hold your shares in a brokerage or bank account (in “street name”), your broker or bank cannot vote your shares unless you complete, sign, date and return the enclosed proxy voting form. Voting now will allow the Fund to minimize the expense incurred with further reminder mailings and solicitations.

If you have questions or need assistance in voting your shares, please call Georgeson Inc. at 1-866-856-6388.

Thank you for voting.
