Dear Plan Sponsor:

I am writing to you about an important proxy campaign for the DWS Funds. Our records indicate that on January 3, 2008 a retirement plan sponsored by you held shares of a DWS Fund. As plan sponsor, you may have voting discretion on behalf of the DWS Fund shares held by the retirement plan. As a valued client of DWS Scudder Retirement Services, we wanted to take this opportunity to remind you that we have not yet received your vote relating to the proposals that will be voted on at the Special Meeting of DWS Fund shareholders, which has been adjourned to May 1, 2008.

Your vote is important and by voting now you can help ensure that we receive enough votes to hold the Special Meeting and avoid additional solicitation expenses.

Accompanying this letter is your proxy card and a return envelope. We previously sent you a proxy statement explaining the proposals to be voted on at the Special Meeting. We encourage you to carefully review the proposals and vote your shares today.

Voting is easy and takes only a few minutes. Choose one of the following methods:

• Log on to the Web site noted on your proxy, enter your control number printed on the card and vote by following the on-screen prompts.

• Call the phone number on the proxy card, enter the control number printed on the card and follow the touchtone prompts.

• Mail in your completed and signed proxy card in the envelope provided.

If you have any questions regarding the proposals or voting process or if you need assistance, please call the DWS Funds’ proxy solicitor, D. F. King & Co., Inc., toll-free at 1-800-714-3305. Additionally, you should feel free to contact your DWS Scudder Retirement Services’ representative with any questions about your retirement plan’s investment in the DWS Funds.

Thank you for your participation in this important matter.

Best Regards,

Roger Gray

Head of Client Service - DWS Scudder Retirement Services
