[logo PIONEER] IMPORTANT INFORMATION ABOUT PIONEER INTERMEDIATE TAX-FREE FUND [CALLOUT] PIONEER INTERMEDIATE TAX-FREE FUND'S BOARD OF TRUSTEES HAS APPROVED A +ROPOSAL TO MERGE THE FUND INTO PIONEER TAX-FREE INCOME FUND The Boards of Trustees for Pioneer Intermediate Tax-Free Fund (the Fund) and Pioneer Tax-Free Income Fund have approved a proposal by Pioneer Investment Management to merge the Fund into Pioneer Tax-Free Income Fund. If shareowners approve the merger, they will become shareowners of the surviving fund--Pioneer Tax-Free Income Fund--which will maintain its same investment objective (described below) and management team, including portfolio manager Mark Winter. The chief reason for this proposal is to enable all shareowners to benefit from the lower expenses currently paid by Pioneer Tax-Free Income Fund. Pioneer Intermediate Tax-Free Fund incurs higher expenses due to its smaller asset size, even with the current voluntary waiver of a portion of its management fees. Expenses could move higher if Pioneer Investment Management decided to discontinue the waiver. The funds have similar investment objectives; both seek a high level of current income exempt from federal income taxes. The Trustees expect that shareowners will receive the same investment advantages as they currently have, yet with the potential for higher returns given Tax-Free Income Fund's lower expenses.
