Since we have not had a response we assume you are satisfied. We ask that you provide us with written assurance that we will be permitted to vote our proxies as directed and that they will be counted so that last years wasteful failure to achieve a quorum can be avoided this year. Thank you. Very truly yours, Phillip Goldstein President Kimball & Winthrop, Inc. Managing General Partner
