           This is the formal agenda for your fund's annual shareholder meeting.
It tells you the  matters you will be asked to vote on and the time and place of
the meeting, in case you want to attend in person.

           TO THE SHAREHOLDERS OF PIONEER INTEREST SHARES:

           The annual meeting of  shareholders  of your fund will be held at the
offices of Hale and Dorr LLP, 60 State Street, 26th Floor, Boston, Massachusetts
on August ___, 2000 at 2:00 p.m., Boston time, to consider the following:

1.   A  proposal  to  approve a new  management  contract  between  the fund and
     Pioneer  Investment  Management,   Inc.,  your  fund's  investment  adviser
     ("Pioneer").  This new  contract  will  take  effect  only if the  proposed
     acquisition of The Pioneer Group, Inc. ("PGI"),  the parent of Pioneer,  by
     UniCredito Italiano S.p.A. ("UniCredito") is consummated;

2.   To elect the eight  trustees of the fund,  as named in the  attached  proxy
     statement,  to serve on the board of trustees until their  successors  have
     been duly elected and qualified;

3.   To ratify the  selection of Arthur  Andersen LLP as the fund's  independent
     public accountants for the fiscal year ending December 31, 2000; and

4.   To consider any other business that may properly come before the meeting.


           YOUR TRUSTEES  RECOMMEND THAT YOU VOTE IN FAVOR OF ALL THE PROPOSALS.
APPROVAL  OF A NEW  MANAGEMENT  CONTRACT  IS  REQUIRED  BECAUSE OF THE CHANGE IN
CONTROL  OF  PGI.  THERE  ARE  NO  MATERIAL  DIFFERENCES  BETWEEN  THE  EXISTING
MANAGEMENT CONTRACT AND THE PROPOSED MANAGEMENT CONTRACT. APPROVAL OF PROPOSAL 1
WILL NOT INCREASE THE MANAGEMENT FEE RATE PAYABLE BY THE FUND.

are entitled to vote at the meeting and any related follow-up meetings.

                                              By Order of the Board of Trustees,

                                  INTRODUCTION

           This proxy  statement  is being used by the board of trustees of your
fund to solicit  proxies to be voted at the annual  meeting of  shareholders  of
your fund.  This  meeting  will be held at the  offices of Hale and Dorr LLP, 60

           This proxy  statement and the enclosed proxy card are being mailed to
shareholders  on or about June ___, 2000. The annual report for the fund for its
most recently completed fiscal year was previously mailed to shareholders.

           The annual  shareholder  meeting is being called to  consider,  among
other things, a proposal related to the proposed acquisition (the "Transaction")
of all of the outstanding shares of The Pioneer Group, Inc. ("PGI"),  the parent
company of the fund's investment adviser,  Pioneer Investment  Management,  Inc.
("Pioneer"),  by  UniCredito  Italiano  S.p.A.  ("UniCredito").  If  Proposal 1,
regarding the approval of the proposed  management  contract (as defined below),
is adopted and the  Transaction  is  consummated,  Pioneer will  continue as the
fund's  investment  adviser.  The  Transaction is  conditioned  upon approval of
Proposal 1 by  shareholders  of the fund and  approval of similar  proposals  by
shareholders   of  other  funds  in  the  Pioneer  Family  of  Funds,   together
representing  at least 92.5% of the  aggregate  assets in the Pioneer  Family of
Funds.  The  Transaction and the terms of the proposed  management  contract are
discussed below.

                             WHO IS ELIGIBLE TO VOTE

           Shareholders  of record of the fund as of the  close of  business  on
June 16,  2000 (the  "record  date") are  entitled  to vote on all of the fund's
business at the annual shareholder  meeting and any adjournments  thereof.  Each
share is entitled to one vote. Shares  represented by properly executed proxies,
unless  revoked  before  or  at  the  meeting,   will  be  voted   according  to
shareholder's instructions. If you sign a proxy, but do not fill in a vote, your
shares will be voted in favor of each of the nominees for trustee and to approve
the other proposals.  If any other business comes before the annual  shareholder
meeting,  your shares will be voted at the  discretion  of the persons  named as
proxies.

THE TRANSACTION

INFORMATION CONCERNING UNICREDITO

           UniCredito is a corporation  organized under the laws of the Republic
of Italy,  and its  shares  trade on the Milan  Stock  Exchange.  UniCredito  is
Italy's second largest banking group, as measured by market capitalization,  and
was formed in 1998 by the merger of  Credito  Italiano  and Rolo Banca 1473 with
Cariverona,  Cassa di Risparmio di Torino and Cassamarca.  Through approximately
3,600 branches  worldwide,  UniCredito  offers a range of services  relating to,
among other things, banking, life and property/casualty  insurance and equipment
leasing.

           UniCredito's  asset  management  subsidiary,   EuroPlus,  is  one  of
Europe's largest and  fastest-growing  asset managers,  with  approximately  $80
billion in assets under management, 90 established mutual funds and 13 new funds
ready to be launched.  EuroPlus currently serves approximately 200 institutional
clients  and over  5,000  high net worth  clients.  Its share of the  retail and
institutional   markets  in  Italy  and  Europe   makes   EuroPlus  the  largest
institutional account manager in Italy, the third largest mutual fund manager in
Italy and the fifth  largest  mutual fund manager in Europe.  EuroPlus  operates
primarily  through two arms:  EuroPlus  Research  and  Management  in Dublin and
EuroPlus SGR in Milan.

           Upon completion of the Transaction,  PGI and EuroPlus will combine to
form  Pioneer  Global  Asset  Management,  a  new  wholly  owned  subsidiary  of
UniCredito with combined assets under  management of over $100 billion.  Pioneer
Global Asset Management will conduct its asset management business through three
operational units:  Pioneer Research & Management  (currently  EuroPlus Research
and  Management),   Pioneer  SGR  (currently  EuroPlus  SGR)  and  Pioneer  U.S.
(currently PGI).

           The principal  executive  offices of UniCredito are located at Piazza
Cordusio 2, 20123 Milan, Italy.

THE TERMS OF THE MERGER AGREEMENT

           At the  closing  of the  Transaction,  UniCredito  will  acquire,  by
merging a wholly  owned  subsidiary  into PGI,  all the issued  and  outstanding
shares  of  common  stock  of  PGI  for an  aggregate  merger  consideration  of
approximately  $1.2  billion  or  $43.50  per  share.  Immediately  prior to the
effective time of the Transaction,  PGI will also distribute to its stockholders
all of the  shares  of a newly  formed  company  that  will  conduct,  after the
effective date of the merger, PGI's gold exploration, timber, Russian investment
management and Eastern European real estate and venture capital businesses.  The
merger  consideration  is not subject to  adjustment,  and there is no financing
condition to the consummation of the Transaction. Messrs. John F. Cogan, Jr. and
David  D.  Tripple,  trustees  of the  fund and  executive  officers  of PGI and
Pioneer,  will  receive a portion of the merger  consideration  in exchange  for
their  shares of PGI,  and Mr.  Cogan  will also  receive a bonus  payment of $1
million upon  consummation of the  Transaction.  Mr. Cogan is expected to become
the Deputy  Chairman  of  Pioneer  Global  Asset  Management  and  non-executive
Chairman of Pioneer U.S. Mr. Tripple is expected to be Chief  Executive  Officer
of Pioneer U.S.

           The  Transaction  is  expected to close  during the third  quarter of
2000,  provided that a number of conditions  set forth in the merger  agreement,
dated as of May 14, 2000,  between PGI and UniCredito (the "Merger  Agreement"),
are met or waived. These conditions include the approval of the Merger Agreement
by PGI's stockholders, the approval of a new management contract by shareholders
of the fund and approval of similar new management  contracts by shareholders of
other funds in the Pioneer Family of Funds, together representing at least 92.5%
of the aggregate  assets in the Pioneer Family of Funds,  and obtaining  certain
regulatory approvals.

           No change in the fund's  portfolio  management team is anticipated to
occur in  connection  with the  Transaction.  PGI has  agreed to  provide  bonus
payments and other benefits to certain Pioneer  personnel in order that there is
no disruption in the quality of services provided to shareholders of the fund in
connection  with the  Transaction.  However,  the Transaction is not conditioned
upon the  continued  employment  of any Pioneer  personnel,  and there can be no
assurance that any particular Pioneer employee will choose to remain employed by
UniCredito or its affiliates.

ANTICIPATED BENEFITS OF THE TRANSACTION

           Pioneer  anticipates  that the Transaction  and its affiliation  with
UniCredito will benefit Pioneer and the fund in a number of ways,  including the
following:

o    Pioneer's  expertise  will be enhanced by the  experience  and expertise of
     UniCredito's  investment management  professionals.  While no change in the
     management of the fund is currently  planned,  Pioneer will be able to draw
     upon the  expertise of  UniCredito's  team of  professionals  to strengthen
     Pioneer's portfolio management capabilities.

o    The  combination  will  provide  additional   opportunities  for  Pioneer's
     personnel  and provide the security of being part of a larger,  financially
     stronger  company.  This development  should further  Pioneer's  ability to
     attract and retain highly qualified staff members.

o    UniCredito  has made the growth of its asset  management  operations  a key
     component of its business plans.  This commitment  should assist Pioneer in
     continuing  to expand its  business,  attract  more  assets to the fund and
     maintain the high level of services it provides to the fund.

                                   PROPOSAL 1

                      APPROVAL OF A NEW MANAGEMENT CONTRACT

SUMMARY

           Pioneer has served as the fund's  investment  adviser since  December
1993.

           Pioneer serves as the investment adviser for each fund in the Pioneer
Family of Funds and for other  institutional  accounts.  Pioneer,  a  registered
investment adviser under the Investment  Advisers Act of 1940, as amended,  is a
wholly  owned  subsidiary  of PGI.  Both Pioneer and PGI are located at 60 State
Street, Boston, Massachusetts 02109.

           At  meetings  of the board of  trustees  for the fund held on May 25,
2000 and June ___, 2000, the trustees, including all of the trustees who are not
"interested persons" of the fund, Pioneer or UniCredito, unanimously approved as
in  the  best  interest  of  shareholders,  and  voted  to  recommend  that  the
shareholders of the fund approve, a proposal to adopt a new management  contract
with Pioneer (the "proposed management contract") effective upon consummation of
the Transaction.

           Shareholders  of the  fund are  being  asked to  approve  the  fund's
proposed management  contract with Pioneer.  The consummation of the Transaction
will  constitute an  "assignment"  (as defined in the Investment  Company Act of
1940 (the "1940 Act")) of the fund's  current  management  contract with Pioneer
(the "existing management contract").  As required by the 1940 Act, the existing
management  contract  provides for its automatic  termination in the event of an
assignment.  Accordingly,  the existing  management contract will terminate upon
the  consummation  of the  Transaction  and a new  management  contract is being
proposed to enable Pioneer to continue to manage the fund.

TERMS OF THE PROPOSED MANAGEMENT CONTRACT AND EXISTING MANAGEMENT CONTRACT

           The  terms  of  the   fund's   proposed   management   contract   are
substantially identical to the terms of the fund's existing management contract,
except for the dates of execution, effectiveness and termination and for certain
non-material  amendments to conform the terms of the management  contract to the
standard form of management  contract for the other funds in the Pioneer  Family
of Funds.  The stated  management fee to be paid by the fund is identical  under
the proposed management contract and the existing management contract. Except as
discussed  under the caption "Other  provisions  under the existing and proposed
management  contracts," all the terms described below with respect to the fund's
proposed  management  contract were contained in the fund's existing  management
contract. The following summary of the proposed management contract is qualified
by reference to the form of proposed  management contract attached to this proxy
statement as EXHIBIT A. Information  regarding Pioneer,  its


                                       3
<PAGE>


principal   executive   officer   and  directors,   another  of  its  investment
company  clients  and  brokerage  policy is  included in EXHIBIT B to this proxy
statement.

           MANAGEMENT  SERVICES.  The  management  services  to be  provided  by
Pioneer to the fund under the  proposed  management  contract  are  identical to
those  provided  by  Pioneer  under the  fund's  existing  management  contract.
Pursuant to the terms of the existing  management  contract,  Pioneer  serves as
investment  adviser to the fund and is responsible for the overall management of
the  fund's  business  affairs  subject  only to the  authority  of the board of
trustees.  Pioneer is authorized to buy and sell  securities  for the account of
the fund and to designate  brokers to carry out such  transactions.  Pioneer may
not make any  purchase  the cost of which  exceeds the fund's  available  liquid
assets and may not make any purchase which would violate any fundamental  policy
or restriction in the fund's  prospectus or statement of additional  information
as in effect from time to time.

           PAYMENT OF EXPENSE AND TRANSACTION  CHARGES.  The proposed management
contract  and the  existing  management  contract  for  the  fund  will  contain
identical  provisions  relating  to the  expenses  to be borne by the fund.  The
fund's existing  management  contract and proposed  management  contract provide
that the expenses  borne by the fund will include:  (i) the charges and expenses
for fund  accounting,  pricing and  appraisal  services  and  related  overhead,
including,  to the extent such services are performed by personnel of Pioneer or
its affiliates, office space and facilities and personnel compensation, training
and benefits;  (ii) the charges and expenses of auditors;  (iii) the charges and
expenses of any custodian, transfer agent, plan agent, dividend disbursing agent
and registrar appointed by the fund; (iv) issue and transfer taxes chargeable to
the fund in  connection  with  securities  transactions  to which  the fund is a
party; (v) insurance premiums, interest charges, dues and fees for membership in
trade  associations  and all taxes and  corporate  fees  payable  by the fund to
federal, state or other governmental  agencies;  (vi) fees and expenses involved
in registering and maintaining  registrations of the fund and/or its shares with
federal regulatory  agencies,  state or blue sky securities agencies and foreign
jurisdictions,  including the  preparation  of  prospectuses  and  statements of
additional  information for filing with such regulatory  authorities;  (vii) all
expenses of shareholders' and trustees' meetings and of preparing,  printing and
distributing  prospectuses,   notices,  proxy  statements  and  all  reports  to
shareholders and to governmental agencies;  (viii) charges and expenses of legal
counsel  to the  fund and the  trustees;  (ix) any  distribution  expenses;  (x)
compensation  of those  trustees  of the fund who are not  affiliated  with,  or
"interested  persons" of,  Pioneer,  the fund (other than as  trustees),  PGI or
Pioneer Funds Distributor, Inc. ("PFD"); (xi) the cost of preparing and printing
share  certificates;  (xii) interest on borrowed  money,  if any; and (xiii) the
fees and other  expenses  of  listing  the  fund's  shares on the New York Stock
Exchange or any other national stock exchange.
           Under both the existing and the proposed management contracts for the
fund, Pioneer, at its own expense,  will furnish to the fund office space in its
offices or in such other place as may be agreed upon from time to time,  and all
necessary  office  facilities,  equipment and personnel for managing the affairs
and  investments  and supervising the keeping of the books of the fund and shall
arrange, if desired by the fund, for members of Pioneer's  organization to serve
as officers or agents of the fund.

           Also, under both the existing and proposed  management  contracts for
the fund,  Pioneer will pay directly or reimburse the fund for: (i) compensation
(if any) of the trustees who are affiliated  with, or  "interested  persons" (as
defined in the 1940 Act) of,  Pioneer and all officers of the fund as such;  and
(ii) all expenses not  specifically  assumed by the fund where such expenses are
incurred  by Pioneer or by the fund in  connection  with the  management  of the
affairs of, and the investment and reinvestment of the assets of, the fund.

           The fund has  also  entered  into an  administration  agreement  with
Pioneer  pursuant to which the fund  authorizes  Pioneer to provide certain fund
accounting  services and legal  services that Pioneer is not required to provide
under the existing  management  contract.  Under the  administration  agreement,
Pioneer is  reimbursed  for its  allocable  portion of its direct  costs of such
services.  The allocable  portion of such costs is based upon the time worked by
Pioneer's  employees rendering such services for the fund as a percentage of the
total  hours  worked by such  employees.  Pioneer's  direct  costs  include  any
out-of-pocket  expenses  incurred  by Pioneer in  rendering  such  services,  an
allocable  portion of the salaries and benefits of the employees  rendering such
services  and  a  reasonable  allocation  of  overhead.  Annual  allocation  and
reimbursement  of these  expenses  is subject to annual  approval  of the fund's
independent trustees.

           MANAGEMENT  FEES.  For  its  services,   Pioneer  is  entitled  to  a
management fee. The method and rate for  calculating  the fund's  management fee
will be the same  under the fund's  proposed  management  contract  as under its
existing  management  contract (such methods and rates are set forth below).  If
the proposed management contract


                                       4
<PAGE>


had  been  in  effect  for  the fund's most recently  completed fiscal year, the
amount of  management  fees  payable  to  Pioneer  by the fund  would  have been
identical to those payable under the existing management contract. THERE WILL BE
NO INCREASE IN THE MANAGEMENT FEE RATE IN CONNECTION WITH THE TRANSACTION.

           The fund pays Pioneer a  management  fee at a rate equal to 0.625% of
the fund's average daily net assets up to $50 million and 0.50% of average daily
net assets in excess of $50 million. The fee is calculated and accrued daily and
paid monthly in arrears.  The aggregate amount of investment  advisory fees paid
by the fund to Pioneer for the fund's most recently  completed fiscal year ended
December  31, 1999 was  $548,109  and was $ ______ for the 12 months ended March
31,  2000.  The existing  management  contract  was most  recently  submitted to
shareholders for approval on July 9, 1996, in connection with the reorganization
of the fund as a Delaware business trust.

OTHER PROVISIONS UNDER THE EXISTING AND PROPOSED MANAGEMENT CONTRACTS

           STANDARD  OF  CARE.  Under  the  existing  and  proposed   management
contracts,  Pioneer  "will not be liable for any error of judgment or mistake of
law or for any loss sustained by reason of the adoption of any investment policy
or the  purchase,  sale, or retention of any security on the  recommendation  of
[Pioneer]. . . ." Pioneer,  however, shall not be protected against liability by
reason of its ". . . willful  misfeasance,  bad faith or gross negligence in the
performance  of its  duties  or by  reason  of  its  reckless  disregard  of its
obligations  and  duties  under"  either the  existing  or  proposed  management
contract.

           PIONEER'S  AUTHORITY.  The existing and proposed management contracts
provide  that  Pioneer  shall  have  full  discretion  to act  for  the  fund in
connection  with the purchase and sale of portfolio  securities  subject only to
the declaration of trust,  bylaws,  currently effective  registrations under the
1940 Act and the  Securities  Act of 1933,  as  amended,  investment  objective,
policies and  restrictions of the fund in effect from time to time, and specific
policies and instructions established from time to time by the trustees.

           PORTFOLIO  TRADING.  The existing and proposed  management  contracts
expressly  permit  Pioneer to engage in portfolio  trading.  For a more detailed
description of Pioneer's current portfolio brokerage practices, see EXHIBIT B to
this proxy statement.

           EXPENSE LIMITATION.  The existing and proposed  management  contracts
provide  that Pioneer may from time to time agree not to impose all or a portion
of its fee or otherwise  take action to reduce  expenses of the fund.  Except as
may  otherwise  be agreed to by  Pioneer,  any such fee  limitation  or  expense
reduction is  voluntary  and may be  discontinued  or modified by Pioneer at any
time. The existing and proposed management contracts for the fund also contain a
provision which limits the fund's operating expenses to the highest limit set by
state  securities  law.  The proposed  management  contract for the fund will be
revised to eliminate  this  provision  because it is no longer  necessary  under
federal securities laws.

           OTHER PROVISIONS. The proposed management contract will be amended to
expressly  permit  Pioneer  to  delegate  its  investment  advisory  duties to a
subadviser.  Any use of  subadvisers  would be subject to approval by the fund's
independent  trustees.  The existing and proposed  management  contracts for the
fund contain a provision  which prohibits the fund from using the name "Pioneer"
in the event  Pioneer or any of its  affiliates  cease to act as the  investment
adviser of the fund.

           Each existing and proposed  management  contract includes  provisions
that provide that: (i) the law of The Commonwealth of Massachusetts shall be the
governing law of the contract; (ii) Pioneer is an independent contractor and not
an employee of the fund; (iii) the contract is the entire agreement  between the
parties with respect to the matters described therein;  (iv) the contract may be
executed using  counterpart  signature  pages;  and (v) invalid or unenforceable
provisions of the contract are severable and do not render the entire  agreement
invalid or unenforceable.

MISCELLANEOUS

           If approved by shareholders,  the fund's proposed management contract
will become effective upon the consummation of the Transaction and will continue
in effect for an initial period of [two years] and thereafter will continue from
year to year  subject to annual  approval  by the board of  trustees in the same
manner as the  existing  management  contract.  The fund's  proposed  management
contract  terminates  if  assigned  (as  defined  in the  1940


                                       5
<PAGE>


Act)  and  may  be  terminated   without penalty by either party, by vote of its
board or by a vote of a majority of the  outstanding  voting  securities  of the
fund and upon 60 days' written notice.

           The  trustees of the fund  determined  that the terms of the proposed
management  contract are fair and  reasonable  and that approval of the proposed
management  contract on behalf of the fund is in the best interests of the fund.
The trustees also  determined  that the  continuity and efficiency of management
services  after the  consummation  of the  Transaction  can best be  assured  by
approving the proposed  management  contract on behalf of the fund. The trustees
believe that the proposed  management  contract will enable the fund to continue
to enjoy high  quality  investment  advisory  services  at costs which they deem
appropriate,  reasonable  and  in  the  best  interests  of  the  fund  and  its
shareholders.

           In evaluating the proposed management contract, the trustees reviewed
materials furnished by Pioneer and UniCredito,  including  information regarding
Pioneer, UniCredito, their respective affiliates and their personnel, operations
and financial condition. The trustees also reviewed the terms of the Transaction
and its possible effects on the fund and its  shareholders.  Representatives  of
Pioneer  discussed with the trustees the anticipated  effects of the Transaction
and, together with a representative  of UniCredito,  indicated their belief that
as a consequence of the proposed transaction, the operations of the fund and the
capabilities of Pioneer to provide advisory and other services to the fund would
not be adversely affected and should be enhanced by the resources of UniCredito,
though  there  could be no  assurance  as to any  particular  benefits  that may
result.  The  trustees  also  reviewed  information   regarding  the  investment
performance  of the  fund  on an  absolute  basis  and  compared  to  investment
companies  with similar  investment  objectives and policies (the "peer group"),
the fees and  expenses  incurred by the fund  compared to its peer group and the
profitability to Pioneer in managing the fund.

           The trustees also  specifically  considered the following as relevant
to their recommendations: (1) that the terms of the proposed management contract
are substantially identical to those of the existing management contract, except
for a different  execution date,  effective date,  termination  date and certain
non-material changes; (2) the favorable history,  reputation,  qualification and
background of Pioneer and  UniCredito,  as well as the  qualifications  of their
personnel  and  their  respective  financial  conditions;  (3)  that the fee and
expense ratios of the fund are reasonable given the quality of services expected
to be  provided  and are  comparable  to the fee and  expense  ratios of similar
mutual funds; (4) the relative  performance of the fund since Pioneer has served
as its investment adviser to comparable mutual funds and unmanaged indices;  (5)
the  commitment of PGI to pay the expenses of the funds in  connection  with the
Transaction  so that  shareholders  of the  fund  would  not  have to bear  such
expenses; (6) the possibility of benefits that may be realized by the funds as a
result of Pioneer's  affiliation  with  UniCredito,  including  any resources of
UniCredito  that would be  available  to Pioneer;  (7) the  Transaction  ensures
continuity  of management  of the fund and reduces  vulnerability  to changes in
control  of PGI that may be  adverse  to the  fund's  interests;  and (8)  other
factors  deemed  relevant by the trustees.  The trustees  deemed the factors set
forth in clauses (1),  (2), (3) and (7) to be  particularly  persuasive in their
decision to recommend to the fund's  shareholders that they approve the proposed
management  contract.  The trustees considered the other factors set forth above
to be relevant to a lesser  extent than those set forth in clauses (1), (2), (3)
and (7). The trustees did not attach a weighting to any particular factor.

SECTION 15(F) OF THE 1940 ACT

           Section 15(f) of the 1940 Act permits,  in the context of a change in
control of an investment adviser to a registered investment company, the receipt
by such investment  adviser (or any of its affiliated  persons) of any amount or
benefit in connection  with such sale, as long as two  conditions are satisfied.
First,  there may not be imposed an "unfair burden" on the investment company as
a  result  of the  sale of such  interest,  or any  express  or  implied  terms,
conditions or understandings  applicable  thereto.  The term "unfair burden," as
defined in the 1940 Act,  includes any  arrangement  during the two-year  period
after  the  transaction  whereby  the  investment  adviser  (or  predecessor  or
successor adviser), or any interested person of any such adviser, receives or is
entitled  to  receive  any  compensation,   directly  or  indirectly,  from  the
investment  company  or its  security  holders  (other  than  fees for bona


                                       6
<PAGE>


fide   investment   advisory   or   other  services),  or  from  any  person  in
connection with the purchase or sale of securities or other property to, from or
on behalf of the  investment  company  (other than  ordinary  fees for bona fide
principal underwriting services).

           The  board  of  trustees  has not  been  advised  by  Pioneer  of any
circumstances  arising from the Transaction  that might result in the imposition
of an "unfair burden" being imposed on the fund. Moreover, UniCredito has agreed
in the  Merger  Agreement  that  (i) for a  period  of  three  years  after  the
consummation  of  the  Transaction,  UniCredito  and  its  affiliates  will  use
reasonable  efforts to assure that at least 75% of the fund's  board of trustees
are not  "interested  persons"  (as  defined in the 1940 Act) of  UniCredito  or
Pioneer,  (ii)  for  two  years  after  the  consummation  of  the  Transaction,
UniCredito and its affiliates will refrain from imposing, or agreeing to impose,
an unfair burden on the fund, and (iii)  UniCredito and its affiliates  will use
reasonable  efforts to ensure that any  vacancy on the fund's  board of trustees
shall be filled by a person who is not an  "interested  person" of UniCredito or
Pioneer and who has been selected by the fund's independent trustees.

TRUSTEES' RECOMMENDATION

           The  independent  trustees of the fund held  meetings to consider the
proposed  management  contract and the Transaction on May 25, 2000 and June ___,
2000, and the entire board of trustees considered the proposal at a meeting held
on June ___,  2000.  Based on their  evaluation of the  materials  presented and
assisted by the advice of independent  counsel, the trustees at the meeting held
on June ___, 2000,  including all the trustees who are not "interested  persons"
of the fund, Pioneer or UniCredito,  unanimously concluded that the terms of the
proposed management  contract for the fund are reasonable,  fair and in the best
interests of the fund and its  shareholders,  and that the fees provided therein
are fair and  reasonable  in light of the usual and  customary  charges  made by
others for services of the same nature and quality. The trustees, by a vote cast
at the meeting,  approved and voted to recommend to the shareholders of the fund
that they approve the proposed management contract.

           If  the  shareholders  of  the  fund  do  not  approve  the  proposed
management contract and the Transaction is consummated, the trustees of the fund
would  consider  what further  action to take  consistent  with their  fiduciary
duties to the fund.  Such  actions may include  obtaining  for the fund  interim
investment  advisory  services  at cost or at the  current  fee rate either from
Pioneer or from another advisory organization.  Thereafter,  the trustees of the
fund would either negotiate a new investment advisory agreement with an advisory
organization selected by the trustees or make other appropriate arrangements. In
the event the Transaction is not consummated, Pioneer would continue to serve as
investment adviser of the fund pursuant to the terms of the existing  management
contract.

REQUIRED VOTE

           As provided under the 1940 Act,  approval of the proposed  management
contract  will  require  the  vote  of a  majority  of  the  outstanding  voting
securities  of the  fund.  In  accordance  with the 1940 Act and as used in this
Proposal 1, a "majority of the outstanding  voting securities" of the fund means
the lesser of (1) 67% or more of the shares of the fund present at a shareholder
meeting  if the  owners  of  more  than  50%  of the  shares  of the  fund  then
outstanding  are  present  in person  or by  proxy,  or (2) more than 50% of the
outstanding shares of the fund entitled to vote at the shareholder meeting.

           However, in addition to the legal requirement under the 1940 Act, the
consummation of the Transaction is conditioned upon the approval of the proposed
management  contract  by  shareholders  of the fund and  approval of similar new
management  contracts by  shareholders  of other funds in the Pioneer  Family of
Funds,  together  representing  at least  92.5% of the  aggregate  assets in the
Pioneer Family of Funds.

           FOR  THE  REASONS  SET  FORTH  ABOVE,   THE  TRUSTEES  OF  YOUR  FUND
UNANIMOUSLY RECOMMEND THAT SHAREHOLDERS VOTE IN FAVOR OF THE PROPOSED MANAGEMENT
CONTRACT.

                                   PROPOSAL 2

                          ELECTION OF BOARD OF TRUSTEES

           Shareholders  of the fund are being asked to consider the election of
eight  nominees to the board of trustees of the fund.  All of the  nominees  for
election to the fund's  board  currently  serve as trustees  for the fund.  Each
trustee will be elected to hold office until the next meeting of shareholders or
until his or her successor is elected and qualified.  Each nominee has consented
to being named in this proxy  statement and indicated his or her  willingness to
serve if elected.  If any nominee  should be unable to serve,  an event which is
not anticipated,  the persons named as proxies may vote for such other person as
shall be  designated  by the fund's board of trustees.  The persons named on the
accompanying  proxy  card  intend  to  vote  at the  meeting  (unless  otherwise
directed) for the election of the nominees named below as trustees of the fund.

           The following  table sets forth each nominee's  position(s)  with the
fund, and his or her age,  address,  principal  occupation and employment during
the past five years and any other  directorship  held.  The table also indicates
the year  during  which he or she  first  became a  trustee  of the fund and the
number of shares of the fund  beneficially  owned by each  nominee,  directly or
indirectly, on May 31, 2000.

                          RATIFICATION OF SELECTION OF
                         INDEPENDENT PUBLIC ACCOUNTANTS

           The firm of Arthur Andersen LLP has served as your fund's independent
public  accountants  since 1994.  Audit  services  during the fiscal year ending
December  31,  2000  will  consist  of  examinations  of  the  fund's  financial
statements  and reviews of the fund's  filings with the  Securities and Exchange
Commission.

           The fund's  board of  trustees,  including a majority of the trustees
who are not  "interested  persons" of the fund, PGI or UniCredito,  has selected
Arthur Andersen LLP as the fund's  independent public accountants for the fiscal
year ending  December  31,  2000,  subject to  shareholder  ratification  at the
meeting.  A representative of Arthur Andersen LLP is expected to be available at
the meeting to make a statement  if he or she desires to do so and to respond to
appropriate  questions.  Arthur Andersen LLP has advised the fund that it has no
direct or indirect financial interest in the fund.

REQUIRED VOTE

           The  ratification  of the  selection  of Arthur  Andersen LLP as your
fund's  independent  public  accountants for the fiscal year ending December 31,
2000 requires the affirmative  vote of a majority of the fund's shares,  present
in person or by proxy and entitled to vote at the meeting.

RECOMMENDATION

           THE TRUSTEES OF YOUR FUND UNANIMOUSLY RECOMMEND THAT YOU VOTE FOR THE
RATIFICATION  OF  ARTHUR  ANDERSEN  LLP  AS  YOUR  FUND'S   INDEPENDENT   PUBLIC
ACCOUNTANTS FOR THE FISCAL YEAR ENDING DECEMBER 31, 2000.

                       INFORMATION CONCERNING THE MEETING

OUTSTANDING SHARES AND QUORUM

           As of the record date,  [7,841,345.85]  shares of beneficial interest
of the fund were outstanding.  Only shareholders of record as of the record date
are  entitled  to  notice  of and to  vote at the  meeting.  A  majority  of the
outstanding  shares of the fund that are  entitled to vote will be  considered a
quorum for the transaction of business.

OWNERSHIP OF SHARES OF THE FUND

           To the knowledge of the fund, as of the record date, no persons owned
of record or beneficially 5% or more of the outstanding shares of the fund as of
May 31, 2000 except that Cede and Co., Box 20, Bowling Green Station,  New York,
NY 10004-0001, held 5,351,029 shares as nominee.

SHAREHOLDER PROPOSALS

           Shareholder  proposals  to  be  presented  at  the  next  meeting  of
shareholders,  whenever held, must be received at the fund's  offices,  60 State
Street, Boston, Massachusetts 02109, at a reasonable time prior to the trustees'
solicitation of proxies for the meeting and must comply with the requirements of
Rule 14a-8 under the Exchange Act. The submission by a shareholder of a proposal
for inclusion in a proxy  statement does not guarantee that it will be included.
The Fund currently expects to hold the next annual  shareholders'  meeting on or
about June 19, 2001, which date is subject to change.


                                       13
<PAGE>


SHARES HELD IN RETIREMENT PLANS

           The trustee or custodian of certain  retirement plans is permitted to
vote any shares held in such plans in  proportion  to the  percentages  voted by
shareholders  in person and by proxy, or in some cases, if necessary to obtain a
quorum.

PROXIES, QUORUM AND VOTING AT THE MEETING

           Any  shareholder  who has given his or her proxy to  someone  has the
power to revoke  that proxy at any time prior to its  exercise  by  executing  a
superseding  proxy or by  submitting a notice of  revocation to the secretary of
the fund. In addition, although mere attendance at the meeting will not revoke a
proxy,  a  shareholder  present at the meeting may withdraw his or her proxy and
vote in person. All properly executed and unrevoked proxies received in time for
the meeting will be voted in accordance with the  instructions  contained in the
proxies.  If no instruction is given, the persons named as proxies will vote the
shares  represented  thereby in favor of the proposals  described above and will
use their  best  judgment  in  connection  with the  transaction  of such  other
business as may properly come before the meeting or any adjournment thereof.

           A  majority  of the  shares  entitled  to vote,  present in person or
represented by proxy,  constitutes a quorum for the transaction of business with
respect to any proposal (unless otherwise noted in the proxy statement).  In the
event that at the time any session of the meeting is called to order a quorum is
not present in person or by proxy,  the persons  named as proxies may vote those
proxies which have been received to adjourn the  shareholder  meeting to a later
date. In the event that a quorum is present but sufficient votes in favor of any
of the  proposals,  including  the  election  of the  nominees  to the  board of
trustees,  have not been received,  the persons named as proxies may propose one
or more adjournments of the shareholder  meeting to permit further  solicitation
of proxies with respect to such proposal.  Any such adjournment will require the
affirmative  vote of more  than one half of the  shares of the fund  present  in
person or by proxy at the  session of the meeting to be  adjourned.  The persons
named as proxies  will vote those  proxies  which they are  entitled  to vote in
favor of any such proposal in favor of such an  adjournment  and will vote those
proxies  required  to be  voted  against  any  such  proposal  against  any such
adjournment.  A shareholder vote may be taken on one or more of the proposals in
the  proxy  statement  prior to such  adjournment  if  sufficient  votes for its
approval have been received and it is otherwise  appropriate.  Such vote will be
considered  final  regardless  of whether  the  meeting is  adjourned  to permit
additional solicitation with respect to any other proposal.

           Shares of the fund  represented  in  person  or by  proxy,  including
shares which abstain or do not vote with respect to a proposal,  will be counted
for  purposes  of  determining  whether  there  is  a  quorum  at  the  meeting.
Accordingly,  an abstention  from voting has the same effect as a vote AGAINST a
proposal.  However,  if a broker or  nominee  holding  shares in  "street  name"
indicates  on the proxy card that it does NOT have  discretionary  authority  to
vote on a proposal,  those shares will not be considered present and entitled to
vote on that proposal.  Thus, a "broker non-vote" has no effect on the voting in
determining  whether a  proposal  has been  adopted by 67% or more of the fund's
shares  present  at the  meeting,  if more  than 50% of the  outstanding  shares
(excluding the "broker  non-votes")  are present or  represented.  However,  for
purposes of determining  whether a proposal has been adopted by more than 50% of
the outstanding shares of the fund, a "broker non-vote" has the same effect as a
vote against that proposal because shares represented by a "broker non-vote" are
considered to be outstanding shares.

OTHER BUSINESS

           While the meeting has been called to transact any  business  that may
properly  come before it, the only matters  that the trustees  intend to present
are  those  matters  stated  in  the  attached   notice  of  annual  meeting  of
shareholders.  However,  if any  additional  matters  properly  come  before the
meeting,  and on all matters incidental to the conduct of the meeting, it is the
intention  of the  persons  named in the  enclosed  proxy  to vote the  proxy in
accordance  with  their  judgment  on  such  matters  unless  instructed  to the
contrary.

METHOD OF SOLICITATION AND EXPENSES

           The cost of preparing,  assembling  and mailing this proxy  statement
and the attached notice of annual meeting of shareholders  and the  accompanying
proxy card will be borne by PGI. In addition to soliciting  proxies by mail, PGI
may, at its expense, have one or more of the fund's officers, representatives or
compensated  third-party  agents,  including  Pioneer,  PSC and PFD,  aid in the
solicitation of proxies by personal interview or telephone and telegraph and may
request  brokerage  houses and other  custodians,  nominees and  fiduciaries  to
forward proxy


                                       14
<PAGE>


soliciting  material  to  the  beneficial  owners of  the  shares held of record
by such persons.  PGI has retained  [____________] to assist in the solicitation
of proxies. Shareholders who have not voted their proxies in a timely manner may
receive a telephone call from [_______] in an effort to urge them to vote.

           The fund may also arrange to have votes  recorded by  telephone,  the
internet or other  electronic  means.  The voting  procedures used in connection
with such voting methods are designed to authenticate  shareholders' identities,
to allow shareholders to authorize the voting of their shares in accordance with
their  instructions  and to confirm that their  instructions  have been properly
recorded. If these procedures were subject to a successful legal challenge, such
votes would not be counted at the  shareholder  meeting.  The fund is unaware of
any such  challenge  at this  time.  Shareholders  would be  called at the phone
number the sub-transfer  agent,  Chase Mellon Shareholder  Services,  has in its
records for their accounts,  and would be asked for their Social Security number
or  other  identifying  information.  The  shareholders  would  then be given an
opportunity  to  authorize  proxies  to vote  their  shares  at the  meeting  in
accordance   with  their   instructions.   To  ensure  that  the   shareholders'
instructions have been recorded correctly, they will also receive a confirmation
of their  instructions  in the  mail.  In the case of  automated  telephone  and
internet voting, shareholders would be required to provide their Social Security
number or other identifying information and will receive a confirmation of their
instructions.  A  special  toll-free  number  will  be  available  in  case  the
information contained in the confirmation is incorrect.

           Persons  holding  shares as nominees  will be reimbursed by PGI, upon
request,  for the  reasonable  expenses of mailing  soliciting  materials to the
principals of the accounts.

                      FORM OF PROPOSED MANAGEMENT CONTRACT

           THIS  AGREEMENT  dated  as of this  ___ day of  ______________,  2000
between Pioneer Interest Shares,  a Delaware  business trust (the "Trust"),  and
Pioneer Investment Management, Inc., a Delaware corporation (the "Manager").

                               W I T N E S S E T H

           WHEREAS, the Trust is registered as an open-end management investment
company under the  Investment  Company Act of 1940, as amended (the "1940 Act"),
and has filed with the Securities and Exchange  Commission (the  "Commission") a
registration  statement  for the  purpose of  registering  its shares for public
offering under the Securities Act of 1933, as amended (the "1933 Act").

           WHEREAS,  the parties hereto deem it mutually  advantageous  that the
Manager  should be engaged,  subject to the  supervision of the Trust's Board of
Trustees and officers, to manage the Trust.

           NOW, THEREFORE, in consideration of the mutual covenants and benefits
set forth herein, the Trust and the Manager do hereby agree as follows:

1.   The Manager  will  regularly  provide the Trust with  investment  research,
     advice and supervision and will furnish  continuously an investment program
     for the Trust, consistent with the investment objective and policies of the
     Trust.  The Manager will determine from time to time what securities  shall
     be purchased for the Trust,  what  securities  shall be held or sold by the
     Trust and what portion of the Trust's  assets shall be held  uninvested  as
     cash, subject always to the provisions of the Trust's Certificate of Trust,
     Agreement and Declaration of Trust, By-Laws and its registration statements
     under the 1940 Act and under the 1933 Act covering the Trust's  shares,  as
     filed with the Commission,  and to the investment  objective,  policies and
     restrictions  of the Trust,  as each of the same shall be from time to time
     in effect, and subject,  further,  to such policies and instructions as the
     Board of  Trustees of the Trust may from time to time  establish.  To carry
     out such determinations,  the Manager will exercise full discretion and act
     for the Trust in the same  manner and with the same force and effect as the
     Trust itself might or could do with  respect to  purchases,  sales or other
     transactions,  as well as with  respect to all other  things  necessary  or
     incidental to the furtherance or conduct of such purchases,  sales or other
     transactions.

2.   The Manager will, to the extent  reasonably  required in the conduct of the
     business  of the Trust and upon the Trust's  request,  furnish to the Trust
     research, statistical and advisory reports upon the industries, businesses,
     corporations or securities as to which such requests shall be made, whether
     or not the Trust shall at the time have any investment in such  industries,
     businesses,  corporations  or  securities.  The  Manager  will use its best
     efforts in the preparation of such reports and will endeavor to consult the
     persons  and  sources  believed by it to have  information  available  with
     respect to such industries, businesses, corporations or securities.

3.   The Manager will maintain all books and records with respect to the Trust's
     securities transactions required by subparagraphs (b)(5), (6), (9) and (10)
     and  paragraph  (f) of Rule  31a-1  under the 1940 Act  (other  than  those
     records being  maintained by the custodian or transfer  agent  appointed by
     the Trust) and preserve such records for the periods prescribed therefor by
     Rule 31a-2 under the 1940 Act.  The Manager  will also provide to the Board
     of Trustees such periodic and special  reports as the Board may  reasonably

     Inc.; (xi) the cost of preparing and printing share certificates; and (xii)
     interest on borrowed  money, if any; and (xiii) the fees and other expenses

7.   In addition to the expenses  described in Section 6 above,  the Trust shall
     pay all brokers' and  underwriting  commissions  chargeable to the Trust in
     connection with securities transactions to which the Trust is a party.

8.   The Trust  shall pay to the  Manager,  as  compensation  for the  Manager's
     services  hereunder,  a fee at a rate equal to 0.625% of the Fund's average
     daily net assets up to $50 million and 0.50% of average daily net assets in
     excess of $50 million.  Management fees payable hereunder shall be computed
     daily and paid  monthly in  arrears.  In the event of  termination  of this
     Agreement,  the fee provided in this Section shall be computed on the basis
     of the period ending on the last business day on which this Agreement is in
     effect subject to a pro rata adjustment based on the number of days elapsed
     in the current  month as a  percentage  of the total number of days in such
     month.

9.   The  management  fee payable  hereunder  shall be  computed  daily and paid
     monthly in arrears. In the event of termination of this Agreement,  the fee
     provided in Section 8 shall be  computed on the basis of the period  ending
     on the last business day on which this  Agreement is in effect subject to a
     pro rata  adjustment  based on the number of days  elapsed  in the  current
     month as a percentage of the total number of days in such month.

10.  The  Manager  may from time to time agree not to impose all or a portion of
     its fee otherwise  payable  hereunder (in advance of the time such fee or a
     portion  thereof  would  otherwise  accrue)  and/or  undertake  to  pay  or
     reimburse  the Trust for all or a portion  of its  expenses  not  otherwise
     required to be borne or reimbursed  by the Manager.  Any such fee reduction
     or undertaking may be discontinued or modified by the Manager at any time.

11.  It is  understood  that the Manager  may employ one or more  sub-investment
     advisers (each a "Subadviser") to provide  investment  advisory services to
     the Trust by entering into a written  agreement with each such  Subadviser;
     provided,  that any such agreement first shall be approved by the vote of a
     majority of the Trustees,  including a majority of the Trustees who are not
     "interested persons" (as defined in the 1940 Act) of the Trust, the Manager
     or any such  Subadviser,  and  otherwise  approved in  accordance  with the
     requirements of the 1940 Act or an exemption therefrom. The authority given
     to the Manager in Sections 1 through 13 hereof may be delegated by it under
     any such agreement;  provided,  that any Subadviser shall be subject to the
     same  restrictions and limitations on investments and brokerage  discretion
     as the Manager.  The Trust agrees that the Manager shall not be accountable
     to the Trust or the Trust's  shareholders  for any loss or other  liability
     relating to specific investments  directed by any Subadviser,  even through
     the Manager  retains the right to reverse any such investment  because,  in
     the event a  Subadviser  is  retained,  the Trust and the Manager will rely
     almost  exclusively  on the expertise of such  Subadviser for the selection
     and monitoring of specific investments.


                                      A-2

12.  The Manager  will not be liable for any error of judgment or mistake of law
     or for any loss  sustained  by reason  of the  adoption  of any  investment
     policy  or  the  purchase,  sale,  or  retention  of  any  security  on the
     recommendation  of the Manager,  whether or not such  recommendation  shall
     have  been  based  upon  its  own   investigation   and  research  or  upon
     investigation  and  research  made  by  any  other   individual,   firm  or
     corporation,  but nothing contained herein will be construed to protect the
     Manager against any liability to the Trust or its shareholders by reason of
     willful  misfeasance,  bad faith or gross  negligence in the performance of
     its duties or by reason of its reckless  disregard of its  obligations  and
     duties under this Agreement.

13.  Nothing in this  Agreement will in any way limit or restrict the Manager or
     any of its  officers,  directors,  or  employees  from  buying,  selling or
     trading in any securities for its or their own accounts or other  accounts.
     The Manager may act as an investment  adviser to any other person,  firm or
     corporation,  and may perform  management  and any other  services  for any
     other person,  association,  corporation,  firm or other entity pursuant to
     any  contract  or  otherwise,  and  take  any  action  or do any  thing  in
     connection  therewith  or  related  thereto;  and no  such  performance  of
     management  or other  services or taking of any such action or doing of any
     such thing shall be in any manner  restricted or otherwise  affected by any
     aspect of any relationship of the Manager to or with the Trust or deemed to
     violate or give rise to any duty or  obligation of the Manager to the Trust
     except as otherwise  imposed by law. The Trust recognizes that the Manager,
     in effecting  transactions for its various accounts, may not always be able
     to take or liquidate  investment positions in the same security at the same
     time and at the same price.

14.  In connection  with purchases or sales of securities for the account of the
     Trust, neither the Manager nor any of its directors,  officers or employees
     will act as a  principal  or agent or  receive  any  commission  except  as
     permitted by the 1940 Act. The Manager shall arrange for the placing of all
     orders for the purchase and sale of securities for the Trust's account with
     brokers  or dealers  selected  by the  Manager.  In the  selection  of such
     brokers or dealers and the placing of such orders,  the Manager is directed
     at all  times to seek for the Trust the most  favorable  execution  and net
     price available except as described  herein.  It is also understood that it
     is  desirable  for the Trust that the Manager  have access to  supplemental
     investment and market research and security and economic  analyses provided
     by brokers who may execute  brokerage  transactions at a higher cost to the
     Trust than may result when  allocating  brokerage  to other  brokers on the
     basis  of  seeking  the  most  favorable  price  and  efficient  execution.
     Therefore,  the Manager is  authorized to place orders for the purchase and
     sale of securities  for the Trust with such  brokers,  subject to review by
     the  Trust's  Trustees  from time to time with  respect  to the  extent and
     continuation of this practice.  It is understood that the services provided
     by such brokers may be useful to the Manager in connection  with its or its
     affiliates' services to other clients.

15.  On occasions  when the Manager  deems the purchase or sale of a security to
     be in the best interest of the Trust as well as other clients,  the Manager
     may, to the extent permitted by applicable laws and regulations,  aggregate
     the  securities  to be sold or  purchased  in  order  to  obtain  the  best
     execution  and  lower  brokerage  commissions,   if  any.  In  such  event,
     allocation of the  securities so purchased or sold, as well as the expenses
     incurred in the  transaction,  will be made by the Manager in the manner it
     considers  to be the most  equitable  and  consistent  with  its  fiduciary
     obligations to the Trust and to such clients.

16.  This Agreement  shall become  effective on the date hereof and shall remain
     in force until  _____________,  2002 and from year to year thereafter,  but
     only so  long  as its  continuance  is  approved  in  accordance  with  the
     requirements  of the 1940 Act or an  exemption  therefrom,  subject  to the
     right of the Trust and the Manager to terminate  this  contract as provided
     in Section 17 hereof.

17.  Either party hereto may, without penalty,  terminate this Agreement by vote
     of its Board of Trustees or Directors,  as the case may be, or by vote of a
     "majority of the  outstanding  voting  securities"  (as defined in the 1940
     Act) of the Trust or the Manager,  as the case may be, and the giving of 60
     days' written notice to the other party.

18.  This  Agreement  shall   automatically   terminate  in  the  event  of  its
     assignment.  For purposes of this Agreement,  the term  "assignment"  shall
     have the meaning given it by Section 2(a)(4) of the 1940 Act.

19.  The Trust  agrees that in the event that neither the Manager nor any of its
     affiliates  acts as an  investment  adviser to the  Trust,  the name of the
     Trust will be changed to one that does not  contain the name  "Pioneer"  or
     otherwise suggest an affiliation with the Manager.


                                      A-3

20.  The Manager is an  independent  contractor and not an employee of the Trust
     for any purpose.  If any occasion  should arise in which the Manager  gives
     any advice to its clients  concerning the shares of the Trust,  the Manager
     will act solely as  investment  counsel for such clients and not in any way
     on behalf of the Trust.

21.  This Agreement  states the entire  agreement of the parties hereto,  and is
     intended to be the complete and exclusive statement of the terms hereof. It
     may not be added to or changed  orally and may not be modified or rescinded
     except by a writing signed by the parties hereto and in accordance with the
     1940 Act, when applicable.

22.  This  Agreement  and all  performance  hereunder  shall be  governed by and
     construed in accordance with the laws of The Commonwealth of Massachusetts.

23.  Any term or provision of this Agreement  which is invalid or  unenforceable
     in any  jurisdiction  shall, as to such  jurisdiction be ineffective to the
     extent of such invalidity or unenforceability  without rendering invalid or
     unenforceable  the  remaining  terms or  provisions  of this  Agreement  or
     affecting the validity or  enforceability of any of the terms or provisions
     of this Agreement in any other jurisdiction.

24.  This Agreement may be executed  simultaneously in two or more counterparts,
     each of which shall be deemed an original,  but all of which together shall
     constitute one and the same instrument.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed by their duly  authorized  officers and their seal to be hereto affixed
as of the day and year first above written.

SERVICES PROVIDED TO THE FUND BY AFFILIATES OF PIONEER

         PSC  serves as the  fund's  transfer  agent and  shareholder  servicing
agent. Under the terms of its contract with the fund, PSC's duties include:  (i)
processing  sales,  redemptions  and  exchanges  of  shares  of the  fund;  (ii)
distributing  dividends and capital  gains to  shareholder  accounts;  and (iii)
maintaining  certain  account  records  and  responding  to routine  shareholder
inquires.  PSC will  continue to provide  these  services  after the approval by
shareholders  of  the  proposed  management  contract.  For  its  most  recently
completed fiscal year, the fund paid a total of $117,268 in transfer agency fees
to PSC.

           The fund has entered into an  administration  agreement  with Pioneer
pursuant to which  certain  accounting  and legal  services,  which are expenses
payable by the fund under the existing  management  contract,  are  performed by
Pioneer and pursuant to which Pioneer is  reimbursed  for its costs of providing
such  services.  Pioneer will continue to perform its services to the fund under
the administration  agreement after the approval by shareholders of the proposed
management contract.  For its most recently completed fiscal year, the fund paid
a total of $31,570 to Pioneer for such services.

PIONEER'S PORTFOLIO TRANSACTION POLICY

           All orders  for the  purchase  or sale of  portfolio  securities  are
placed on behalf of the fund by Pioneer  pursuant to authority  contained in the
existing and proposed  management  contracts.  In selecting  brokers or dealers,
Pioneer  considers  factors  relating to  execution  on the best  overall  terms
available,  including, but not limited to, the size and type of the transaction;
the nature and character of the markets of the security to be purchased or sold;
the execution  efficiency,  settlement capability and financial condition of the
dealer;  the dealer's execution services rendered on a continuing basis; and the
reasonableness of any dealer spreads.

           Pioneer may select  broker-dealers  which  provide  brokerage  and/or
research services to the fund and/or other investment companies or institutional
or other accounts managed by Pioneer.  Such research services must be lawful and
must  provide  appropriate  assistance  to  Pioneer  in the  performance  of its
investment decision-making  responsibilities and could include advice concerning
the value of securities; the advisability of investing in, purchasing or selling
securities;  the  availability  of  securities  or the  purchasers or sellers of
securities;   providing   stock  quotation   services,   credit  rating  service
information and comparative fund  statistics;  furnishing  analysis,  electronic
information  services,  manuals  and  reports  concerning  issuers,  industries,
securities,  economic factors and trends,  portfolio strategy and performance of
accounts  and  particular   investment   decisions;   and  effecting  securities
transactions and performing  functions incidental thereto (such as clearance and
settlement).

           In circumstances  where two or more  broker-dealers  offer comparable
prices and executions, preference may be given to a broker-dealer which has sold
shares of other investment  companies  managed by Pioneer.  This policy does not
imply  a  commitment   to  execute  all  portfolio   transactions   through  all
broker-dealers that sell shares of the fund. In addition,  if Pioneer determines
in good faith  that the amount of  commissions  charged  by a  broker-dealer  is
reasonable  in  relation to the value of the  brokerage  and  research  services
provided  by  such   broker-dealer,   the  fund  may  pay  commissions  to  such
broker-dealer in an amount greater than the amount another firm may charge.


                                      B-1

This  information  might  be  useful to  Pioneer  in  providing  services to the
fund as well as to other  investment  companies or accounts  managed by Pioneer,
although  not all of such  research  may be  useful to the fund  generating  the
commission credits.  Conversely, such information provided to Pioneer by brokers
and dealers through whom other clients of Pioneer effect securities transactions
might be useful to Pioneer in  providing  services  to the fund.  The receipt of
such research is not expected to reduce  Pioneer's normal  independent  research
activities;  however,  it enables Pioneer to avoid the additional  expense which
might  otherwise  be  incurred  if it  were to  attempt  to  develop  comparable
information through its own staff.
