Dear Fellow Shareowner,

[callout in left margin] VOTING YOUR SHARES BY MAIL OR FAX IS QUICK AND EASY.
EVERYTHING YOU NEED IS ENCLOSED.

On April 21, 1998, and April 30, 1998, your Fund held shareowner meetings to
vote on several important proposals. Enough shareowners voted to obtain the
required response for three of the proposals, all of which shareowners approved.
(The proposals approved at the April 21 and April 30 meetings are listed on the
back of this letter.)

Unfortunately, not enough shareowners responded to obtain the required vote for
the other proposal, Proposal 3. The meeting date for Proposal 3 has been
adjourned, or postponed, until June 18, 1998. You have a final opportunity to
voice your opinion on Proposal 3, and we hope you take time now to vote on the
proposal.

Please take a moment to read Proposal 3 and cast your vote.

[bullet]  PROPOSAL 3:
          ALLOW THE FUND TO BE REORGANIZED AS A SEPARATE DELAWARE BUSINESS
          TRUST. Currently, Pioneer Growth Trust is registered as a single
          Massachusetts business trust with three funds, one of which is your
          Fund. As a separate Delaware business trust, the Fund and its
          shareowners could benefit from a decreased possibility of shareholder
          and trustee liability and various potential operating efficiencies all
          described in the Proxy Statement.

[callout in left margin] THE BOARD OF TRUSTEES RECOMMENDS THAT YOU VOTE FOR THE
PROPOSAL.

The Fund's Board of Trustees, whose primary role is to protect shareowners'
interests, believe the proposed reorganization is fair and reasonable and
recommend that you vote FOR the proposal. They considered many factors:

[bullet]  THE PROPOSED REORGANIZATION MAY HELP SAVE THE FUND AND SHAREOWNERS
          MONEY.
          As a single Delaware business trust, the Fund would be able to operate
          within the better-defined regulations provided in Delaware. The Fund
          would also have the ability to adapt to new laws without going to the
          expense of a special shareowner meeting, which will help save the
          Fund, and shareowners, money.

[bullet]  A DECREASE IN SHAREOWNER AND TRUSTEE LIABILITY. Delaware law is more
          definitive and specifically protects shareowners and trustees of a
          Delaware business trust from liability for the Fund's debts or
          obligations.

[callout in left margin] PLEASE VOTE ON PROPOSAL 3! YOUR VOTE IS EXTREMELY

RATIFY THE SELECTION OF ARTHUR ANDERSEN LLP as the Fund's independent public
