This opinion is being delivered to you in connection with the Agreement and Plan
of Reorganization (the "Agreement") made as of November 1, 2006 by and between
Pioneer Series Trust IV, a Delaware statutory trust, on behalf of its series,

Acquired Fund (the "Acquired Fund Liabilities"), and (ii) the issuance of shares
of beneficial interest of Acquiring Fund (the "Acquiring Fund Shares") to
Acquired Fund, followed by the distribution by Acquired Fund, in liquidation of
Acquired Fund, of the Acquiring Fund Shares to the shareholders of Acquired Fund
and the termination of Acquired Fund (the foregoing together constituting the
"Transaction"). All section references, unless otherwise indicated, are to the
United States Internal Revenue Code of 1986, as amended (the "Code").

Class C shares prospectus for Acquired Fund dated May 1, 2006, as supplemented
on July 3, 2006 and October 1, 2006; (vii) the Class R shares prospectus for
Acquired Fund dated May 1, 2006, as supplemented on June 28, 2006, July 18, 2006

Acquired Fund dated May 1, 2006, as supplemented on June 28, 2006 and July 18,
2006; (ix) the Class A, Class B, Class C, Class R and Investor Class shares

revised on June 28, 2006 and supplemented on July 21, 2006; (x) the Notice of

representation certificates delivered pursuant to the Agreement and relevant to
this opinion (the "Representation Certificates"); and (xiii) such other
documents as we deemed necessary or relevant to our analysis.
In our examination of documents, we have assumed with your permission the
authenticity of original documents, the accuracy of copies, the genuineness of
signatures, the legal capacity of signatories, and the proper execution of
documents. We have further assumed with your permission that (i) all parties to
the Agreement and to any other documents examined by us have acted, and will

as relevant, true and complete; (iii) any representation made in any of the
documents referred to herein "to the knowledge and belief" (or similar
qualification) of any person or party is, and at the consummation of the
Transaction will be, correct without such qualification; and (iv) as to all
matters for which a person or entity has represented that such person is not a
party to, does not have, or is not aware of any plan, intention, understanding,
or agreement, there is no such plan, intention, understanding, or agreement. We
have not attempted to verify independently any of the above assumptions or
representations, but in the course of our representation, nothing has come to
our attention that would cause us to question the accuracy thereof.
The conclusions expressed herein represent our judgment as to the proper
treatment of the Transaction for United States federal income tax purposes based
upon the relevant provisions of the Code, the Treasury Regulations promulgated
thereunder, and interpretations of the foregoing as expressed in court decisions
and administrative determinations, all as in effect on the date of this opinion.
We cannot give any assurance that such laws will not be amended or otherwise
changed after the consummation of the Transaction or that any such changes will
not affect the conclusions expressed herein. We undertake no obligation to
update or supplement this opinion to reflect any changes in law that may occur.
Our opinion represents our best judgment of how a court would decide if
presented with the issues addressed herein and is not binding upon the Internal
Revenue Service (the "IRS") or any court. Thus, no assurance can be given that a
position taken in reliance on our opinion will not be challenged by the IRS or
rejected by a court.
This opinion is limited to the specific United States federal income tax
consequences of the Transaction set forth below. It does not address any other
federal, state, local, or foreign income, estate, gift, transfer, sales, use, or
other tax consequences that may result from the Transaction or any other
transaction, including any transaction undertaken in connection with the
Transaction.
