MEETING OF SHAREHOLDERS

Dear Shareholder:

We recently distributed proxy materials regarding the Meeting of Shareholders of the Nuveen Funds scheduled to take place on Friday, October 12, 2007, at 10:00 a.m., Central time. Our current records indicate that we have not yet received your voting instructions.

Shareholders are being asked to consider several important proposals as more fully described in the materials sent to you. One of the proposals that you are being asked to consider involves the recent announcement by Nuveen Investments, Inc., the parent company of Nuveen Asset Management, your Fund’s investment adviser, of its intention to be acquired by investors led by Madison Dearborn Partners, LLC. The acquisition requires the shareholders to approve a new Investment Management Agreement. Your Fund investment will not change as a result of the change of ownership. The materials previously sent to you contain important information regarding this proposal and other proposals that shareholders are being asked to consider. Please read those materials carefully.

Your Fund’s Board recommends shareholders vote “FOR” each of the proposals.

If you have any questions regarding the proposals, please call Computershare Fund Services, your Fund’s proxy agent, at 1-866-434-7510. Representatives are available Monday through Friday between the hours of 9:00 a.m. and 11:00 p.m. and Saturday from 12:00 p.m. to 6:00 p.m., Eastern Standard Time.
