cash payment of $43.50 for each share of Pioneer common stock. In addition,

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

<TABLE>
<S>  <C>
Q:   WHAT AM I BEING ASKED TO VOTE UPON?
A:   You are being asked to vote to adopt and approve the merger
     agreement between The Pioneer Group, Inc. and UniCredito
     Italiano S.p.A. and the merger.
     If we complete the merger, each share of Pioneer common
     stock, other than shares held by stockholders who perfect
     appraisal rights, will convert into the right to receive a
     cash payment of $43.50. Stockholders of Pioneer will have no
     ongoing ownership stake in the continuing business of
     Pioneer, which will survive as a wholly-owned subsidiary of
     UniCredito. See the merger agreement attached as Annex A and
     "The Merger."
     In addition to the cash payment of $43.50, Pioneer will
     distribute to its stockholders immediately prior to the
     completion of the merger one common share of Harbor Global
     Company Ltd. for every five shares of Pioneer common stock
     held. Immediately after the distribution, all of Harbor
     Global's common shares will be owned by the former
     stockholders of Pioneer. See Harbor Global's information
     statement attached as Annex B and "The
     Merger -- Distribution of Harbor Global Interests."
Q:   WHY IS THE BOARD OF DIRECTORS OF PIONEER AND A SPECIAL
     COMMITTEE OF THE BOARD OF DIRECTORS RECOMMENDING THE MERGER
     WITH UNICREDITO?
A:   A special committee of our board of directors and our board
     of directors have determined that the merger agreement and
     the merger are advisable, fair to you, and in your best
     interests. The special committee and our board of directors
     recommend that you vote to adopt and approve the merger
     agreement and the merger. For more information on the
     reasons for the recommendations of the special committee and
     the board of directors, see "The Merger -- Reasons for the
     Merger."
Q:   WHAT IS UNICREDITO?
A:   UniCredito is an Italian financial institution based in
     Milan, Italy. UniCredito is currently the largest banking
     group in Italy based on market capitalization and the
     eighteenth largest in Europe in terms of total assets.
     UniCredito had consolidated total assets of approximately
     E169 billion ($168 billion) at December 31, 1999, and net
     income of E1.3 billion ($1.3 billion) for its fiscal year
     ended December 31, 1999. In addition, through its asset
     management group of subsidiaries branded EuroPlus,
     UniCredito is one of Europe's largest and fastest growing
     asset managers with approximately $80 billion in assets
     under management at December 31, 1999. See "Information
     About Pioneer and UniCredito."
Q:   IS UNICREDITO'S FINANCIAL CONDITION RELEVANT TO A DECISION
     TO VOTE IN FAVOR OF THE MERGER?
A:   No. UniCredito's obligation to complete the merger is not
     subject to its ability to pay the consideration for all of
     the Pioneer common stock. UniCredito has advised Pioneer
     that it has available cash to pay the merger price. After
     the merger, you will no longer have any continuing financial
     interest in Pioneer, and you will not receive any interest
     in UniCredito.
Q:   WHAT WILL I RECEIVE IF THE MERGER IS APPROVED?
A:   Each share of Pioneer common stock that you own as of the
     effective date of the merger will convert into the right to
     receive a cash payment of $43.50. You also will receive one
     common share of Harbor Global for every five shares of
     Pioneer common stock that you hold at the time of the
     merger.
Q:   WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?
A:   We are working toward completing the merger as quickly as
     possible after the special meeting. We must obtain
     stockholder, client and regulatory approvals first. Our
     current expectation is that the merger will close in
     September 2000.

<TABLE>
<S>        <C>
Q:         WHAT IS HARBOR GLOBAL?
A:         In addition to the cash merger consideration, you will also receive one common share of Harbor Global for each
           five shares of Pioneer common stock that you hold at the time of the merger. Harbor Global is a newly formed
           Bermuda limited duration company owned by Pioneer that will own or operate our businesses and assets that
           UniCredito is not acquiring. These businesses include Pioneer's Russian gold exploration operations, timber
           harvesting and sales, real estate management and investment management, and Polish and Eastern European real
           estate management and venture capital businesses. Harbor Global will liquidate these assets over a five year
           period, which may, in the discretion of Harbor Global's board of directors, be extended for up to three
           additional one year periods. Harbor Global will distribute any proceeds from such liquidations, net of
           expenses and other liabilities, to its shareholders.
           Pioneer will distribute the common shares of Harbor Global pro rata to Pioneer's stockholders immediately
           prior to the merger. The receipt of Harbor Global common shares will be taxable to Pioneer stockholders. We
           currently estimate that we will report for federal income tax purposes that the common shares of Harbor Global
           received in the distribution will have a value of approximately $-- - $-- with respect to each share of
           Pioneer common stock held at the time of the merger (equating to a value of the Harbor Global common shares of
           approximately $-- - $-- per share). However, the actual value we ascribe to the Harbor Global common shares
           for federal income tax purposes may differ from this estimate due to, among other things, changes in the value
           of Harbor Global's assets between December 31, 1999 and the date of the distribution and the number of shares
           of Pioneer common stock outstanding at the effective time of the merger. We will provide you with information
           regarding the value of the Harbor Global common shares you receive in the distribution. However, this
           information is not binding on the Internal Revenue Service, which may assert a different (and possibly higher)
           value for the Harbor Global common shares you receive. Accordingly, there can be no assurance as to the exact
           amount of gain you may recognize as a result of the merger and the distribution, in such a circumstance. The
           value estimated for tax purposes is not necessarily indicative of the price at which you may be able to sell
           Harbor Global common shares.
           The Harbor Global common shares are registered with the Securities and Exchange Commission and are
           transferable. However, there is no current public trading market for Harbor Global common shares, and they
           will not be listed on a securities exchange or The Nasdaq Stock Market(R). Furthermore, Harbor Global does not
           intend to take any actions to facilitate the development of an active trading market. See Harbor Global's
           information statement attached as Annex B.
Q:         WHAT ARE THE FEDERAL INCOME TAX CONSEQUENCES TO ME OF THE MERGER?
A:         In general, we believe you will recognize gain or loss for federal income tax purposes equal to the difference
           between the cash merger consideration and the value of the Harbor Global common shares that you receive and
           your adjusted basis in your shares of Pioneer common stock. Such gain or loss generally will be capital gain
           or loss. However, if the receipt of Harbor Global common shares is treated for tax purposes as a separate
           transaction, it would be a distribution taxable as a dividend at ordinary income tax rates to the extent of
           our current or accumulated earnings and profits, including earnings and profits resulting from the
           distribution of such shares. We cannot assure you that the Internal Revenue Service or the courts will not
           contend that the distribution of Harbor Global common shares is a separate transaction. You may also be
           required to recognize certain income as a result of holding Harbor Global common shares. We urge you to
           consult your own tax advisor regarding the specific tax consequences of the merger and the distribution, as
           well as all tax return reporting requirements, the applicability of federal, state, local and foreign tax laws
           and the effect of any proposed change in the tax laws. For a discussion of certain United States federal
           income tax consequences of the merger and the distribution of Harbor Global common shares, see "The
           Merger -- Material United States Federal Income Tax Consequences."

Q:   WHAT IS THE SPECIAL COMMITTEE OF THE BOARD OF DIRECTORS?
A:   In March 2000, our board of directors determined that we
     should actively pursue strategic alternatives for Pioneer,
     including the possible sale of the company. In order that
     the consideration of potential bids for the company was free
     from conflicts of interest, the board of directors
     established a special committee to evaluate any offer for
     the company and to recommend the acceptance of a bid to the
     board of directors and Pioneer stockholders. The special
     committee is comprised of three directors who are not
     officers of Pioneer.
Q:   WHEN AND WHERE IS THE SPECIAL MEETING?
A:   The special meeting will take place at the offices of Hale
     and Dorr LLP, 26th floor, 60 State Street, Boston,
     Massachusetts 02109, on August --, 2000 at --, local time.
     Stockholders of record at the close of business on -- are
     entitled to notice of and to vote at the meeting.
Q:   WHAT DO I NEED TO DO NOW?
A:   We urge you to read this proxy statement carefully,
     including its annexes, consider how the merger affects you
     as a stockholder and to vote. You also may want to review
     the documents referenced under "Where You Can Find More
     Information."
Q:   HOW DO I VOTE?
A:   You can vote in one of the following ways:
     - Indicate on your proxy card how you want to vote, and sign
     and mail your proxy card in the enclosed return envelope as
       soon as possible so that your shares will be represented
       at the special meeting. If you sign and send in your proxy
       and do not indicate how you want to vote, your proxy will
       be counted as a vote for adoption and approval of the
       merger agreement and the merger;
     - [Call --, toll-free and vote by telephone, or visit the
     website www.eproxy.com/-- and vote on the Internet; or]
     - Attend the special meeting and complete a ballot at that
       time.
Q:   IF MY BROKER HOLDS MY SHARES IN "STREET NAME," WILL MY
     BROKER VOTE MY SHARES FOR ME?
A:   Your broker will not vote your shares for you unless you
     provide instructions on how to vote. It is important,
     therefore, that you follow your broker's directions on how
     to vote your shares. Because stockholders of record holding
     a majority of the outstanding shares of Pioneer common stock
     must adopt and approve the merger agreement and the merger,
     broker non-votes will have the same effect as votes against
     adoption and approval of the merger agreement and the
     merger.
Q:   MAY I CHANGE MY VOTE?
A:   Yes. You may change your vote at any time before your proxy
     is voted at the special meeting. You may do this in one of
     three ways. First, you may send a written notice stating
     that you would like to revoke your proxy. Second, you may
     complete and submit a new proxy card. If you choose either
     of these two methods, you must submit your notice of
     revocation or your new proxy card to us at our principal
     office, to the attention of the secretary. Third, you may
     attend the special meeting and vote in person. Simply
     attending the special meeting, without voting in person,
     will not revoke your proxy. If you have instructed a broker
     to vote your shares, you must follow directions received
     from your broker to change your vote or to vote at the
     special meeting.
Q:   SHOULD I SEND IN MY STOCK CERTIFICATES NOW?
A:   No. If we complete the merger, we will send you written
     instructions on how to receive a cash payment for your
     shares.
Q:   DO I HAVE APPRAISAL RIGHTS UNDER DELAWARE LAW?
A:   You are entitled to appraisal rights in connection with the
     merger if you follow the procedure described under "The
     Merger -- Dissenting Stockholders' Appraisal Rights." If you
     exercise appraisal rights and follow the specified
     procedures, you can receive the judicially determined fair
     value of your shares of Pioneer common stock rather than
     $43.50 per share.

Pursuant to the Agreement and Plan of Merger dated as of May 14, 2000, between
Pioneer and UniCredito, UniCredito will organize a new subsidiary which will be
merged with Pioneer. After the merger, Pioneer will be a wholly-owned subsidiary
of UniCredito. Pioneer's directors will not become directors of UniCredito. Each
share of Pioneer common stock, other than shares held by stockholders who
perfect appraisal rights, will convert into the right to receive $43.50 in cash,
without interest. The merger agreement is attached to this proxy statement as
Annex A. We encourage you to read it.

DISTRIBUTION OF HARBOR GLOBAL (PAGE 27)

In connection with the merger, Pioneer intends to distribute to its stockholders
of record immediately prior to the effective time of the merger all of the
outstanding common shares of Harbor Global Company Ltd. This distribution will
enable you to have a continuing interest in certain of Pioneer's operations in
addition to receiving the merger consideration. At the time of the distribution,
we expect that Harbor Global's assets will consist primarily of the following
businesses and assets currently owned or operated by Pioneer:

     - real estate management and investment management operations in Russia;

     - Polish and Eastern European venture capital investment and management
       operations;

     - Polish and Eastern European real estate management operations;

     - timber harvesting and sales in Russia;

     - gold exploration operations in Russia;

     - the proceeds from the sale of our Teberebie gold mine in Ghana; and

                                        5
<PAGE>   10

     - $25 million in cash.

Harbor Global's liabilities, other than the liabilities of its subsidiaries,
will consist primarily of certain indemnification obligations to Pioneer, the
payment to Pioneer of up to $5 million of the proceeds from the sale of the
Teberebie gold mine, certain funding obligations with respect to the Polish and
Eastern European real estate management operations and the obligation to make
payments to some officers or employees of Harbor Global or its subsidiaries or
employees of Calypso Management, which has agreed to provide services to Harbor
Global, in connection with the termination of their employment with Pioneer or
the continuation of their employment with Harbor Global or its subsidiaries.
Harbor Global will liquidate its assets over a five year period, which may, in
the discretion of Harbor Global's board of directors, be extended for up to
three additional one year periods. Harbor Global will distribute any proceeds,
net of expenses and other liabilities, to its shareholders.

You will receive one common share of Harbor Global for every five shares of
Pioneer common stock you hold immediately prior to the effective time of the
merger. Fractional shares of Harbor Global will not be distributed, but Harbor
Global's distribution agent will aggregate and seek to sell fractional shares,
and the aggregate net cash proceeds, if any, will be distributed pro rata to
Pioneer stockholders entitled to a fractional interest. The receipt of Harbor
Global common shares by Pioneer stockholders will be a taxable distribution to
Pioneer stockholders. We currently estimate that we will report for federal
income tax purposes that the Harbor Global common shares received in the
distribution will have a value of approximately $-- - -- with respect to each
share of Pioneer common stock held at the time of the merger (equating to a
value of the Harbor Global common shares of approximately $-- - $-- per share).
However, the actual value we ascribe to the Harbor Global common shares for
federal income tax purposes may differ due to, among other reasons, changes in
the value of Harbor Global's assets between December 31, 1999 and the date of
the distribution and the number of shares of Pioneer common stock outstanding on
the effective date of the merger. We will provide you with information regarding
the value of the Harbor Global common shares you receive in the distribution.
However, this information is not binding on the Internal Revenue Service, which
may assert a different (and possibly higher) value for the Harbor Global common
shares you receive. Accordingly, there can be no assurance as to the exact
amount of gain you may recognize as a result of the merger and the distribution,
in such a circumstance. The value estimated for tax purposes is not necessarily
indicative of the price at which you may be able to sell Harbor Global common
shares. It is possible that no trading market for the Harbor Global common
shares will develop. The Harbor Global common shares are registered with the
Securities and Exchange Commission and are transferable. However, there is no
current public trading market for Harbor Global common shares, and they will not
be listed on a securities exchange or The Nasdaq Stock Market(R). Furthermore,
Harbor Global does not intend to take any actions to facilitate the development
of an active trading market.

A copy of the information statement included in the registration statement for
Harbor Global is attached hereto as Annex B. This information statement includes
more information regarding Harbor Global, including certain risk factors. You
should read the information statement carefully. If Pioneer stockholders adopt
and approve the merger agreement and the merger, we intend to proceed with the
distribution of Harbor Global's common shares.

VOTE REQUIRED (PAGE 16)

Adoption and approval of the merger agreement and the merger require the
affirmative vote of a majority of the outstanding shares of Pioneer common
stock. Pioneer executive officers entitled to vote approximately 16.2% of the
outstanding shares of Pioneer common stock have entered into a voting agreement
with UniCredito in which they agreed to vote in favor of the merger agreement
and the merger.

BACKGROUND TO THE MERGER (PAGE 21)

In response to the changing nature of the domestic and global investment
management business, our board of directors retained in February 2000 Merrill
Lynch & Co. and Salomon Smith Barney Inc. to conduct financial reviews of
Pioneer's businesses and to advise our board of

                                        6
<PAGE>   11

directors on strategic alternatives. Based on their reviews, our board concluded
that Pioneer would require a substantially more significant presence to continue
to compete successfully in the mutual fund industry and that Pioneer's principal
business is likely to be increasingly dominated by large, globally operating
financial institutions. Because our board of directors did not believe that the
capital resources necessary to develop such a franchise were available to
Pioneer, our board of directors determined to actively pursue strategic
alternatives, including a possible sale of Pioneer. The investment banks advised
Pioneer's board that a sale of Pioneer's investment management operations would
be significantly facilitated if the investment management business was separated
from the businesses of Pioneer Global Investments and the real estate and
investment management operations in Russia. During this period, Lens Investment
Management, LLC, a 4% stockholder of Pioneer, began the solicitation of proxies
for an alternative slate of directors of Pioneer. Lens announced its intention
to cause the company to be sold if its nominees were elected.

While continuing to consider the alternatives available to Pioneer, the board of
directors established a special committee of independent members of the board of
directors and authorized the investment banks to solicit offers to acquire the
company. Pioneer undertook an auction process in which it contacted a broad
range of potential acquirers and allowed such parties to conduct due diligence.
Pioneer received a significant number of offers for the purchase of its
investment management business. UniCredito submitted the most favorable final
offer, and Pioneer entered into negotiation of the merger agreement with
UniCredito. The special committee evaluated the UniCredito offer in comparison
to the other offers for Pioneer as well as to Pioneer's other strategic
alternatives. Pioneer's investment banks delivered oral opinions on the fairness
of the UniCredito offer from a financial point of view to Pioneer's
stockholders.

At meetings on May 10th and May 14th, the special committee, first meeting
separately and then with the entire board, evaluated all offers and recommended
that the UniCredito offer be accepted by the board of directors and stockholders
of Pioneer. The board of directors, at a meeting held on May 14, 2000,
unanimously authorized Pioneer to enter into the merger agreement.

RECOMMENDATION OF PIONEER'S BOARD OF DIRECTORS TO STOCKHOLDERS (PAGE 27)

The Pioneer board of directors, including the special committee, voted
unanimously to adopt and approve the merger agreement and the merger. The board
of directors and the special committee believe that the merger is advisable,
fair to you and in your best interest and recommends that you vote FOR the
proposal to adopt and approve the merger agreement and the merger. In reaching
these conclusions, the special committee and the board of directors were
influenced by several factors, including:

     - In February 2000, our board of directors retained Merrill Lynch & Co. and
       Salomon Smith Barney Inc. to conduct a review of Pioneer's businesses and
       evaluate Pioneer's strategic alternatives. The special committee
       subsequently authorized these investment banks to solicit offers to
       purchase Pioneer. Pioneer received offers from a number of potential
       acquirers. UniCredito's offer was the most favorable offer to Pioneer's
       stockholders.

     - The price to be paid per share represents a 40% premium over the closing
       price of the Pioneer common stock on May 12, 2000, the last trading day
       before the announcement of the terms of the merger agreement with
       UniCredito, a nearly 100% premium over the closing price on March 2,
       2000, the day prior to our announcement that the board of directors had
       authorized the investment banks to actively explore strategic
       alternatives, including a possible sale of Pioneer, and a 159% premium
       over the closing price on February 10, 2000, the day before our
       announcement that we had retained investment banks to conduct a review of
       Pioneer's businesses and to assist the board of directors and management
       in evaluating strategic alternatives. We believe that if we do not
       complete the merger, absent other factors, our stock price may revert
       back to its historical trading range.

     - We believe that long-term success in the investment management business
       requires

                                        7
<PAGE>   12

       significant domestic and global growth and a global presence,
       particularly in Europe. Without that growth, we risk a continuing loss of
       assets under management and market share. We do not believe we have the
       financial resources required to achieve substantial domestic and
       international growth unless we become part of a large financial
       institution.
     - The equity markets in the second half of the 1990s favored managers that
       employed growth and index investment strategies. Pioneer's traditional
       value investment strategy has generally produced returns during the past
       five years below the returns achieved by the general market indicators
       and investment advisors focusing on technology weighted growth
       strategies. These trends, which have continued this year, have adversely
       affected our ability to attract and retain assets in our funds. The net
       assets under management in our United States open-end investment
       companies were approximately $22.0 billion at December 31, 1998, $23.4
       billion at December 31, 1999, and $23.2 billion at March 31, 2000.

WHAT HOLDERS OF PIONEER COMMON STOCK WILL RECEIVE (PAGE 21)

At the effective time of the merger, each share of Pioneer common stock, other
than shares held by stockholders who perfect appraisal rights, will convert into
the right to receive a cash payment of $43.50.

In addition, immediately prior to the effective time of the merger, Pioneer will
distribute to its stockholders of record all of the outstanding common shares of
Harbor Global.

The following table shows the last reported sale price of Pioneer common stock
on The Nasdaq Stock Market(R) (i) on February 10, 2000, the day before our
announcement that we had retained two investment banks to conduct a financial
analysis of Pioneer's businesses and to assist the board of directors and
management in evaluating strategic alternatives, (ii) on March 2, 2000, the
prior to our announcement that the board of directors had authorized the
investment banks to actively explore strategic alternatives, including a
possible sale of the company, (iii) on May 12, 2000, the last trading date prior
to our announcement of the terms of the merger agreement with UniCredito and
(iv) on June 22, 2000, the day before the date of this proxy statement. The
table also indicates the premium that $43.50 per share represents over these
closing prices.

</TABLE>

WHAT HOLDERS OF PIONEER RESTRICTED STOCK AND OPTIONS WILL RECEIVE (PAGE 46)

Prior to the merger, each unvested share of restricted stock issued under
Pioneer's 1995 Restricted Stock Plan and Amended and Restated 1997 Stock
Incentive Plan and each unvested stock option issued under Pioneer's Amended and
Restated 1997 Stock Incentive Plan and 1988 Stock Option Plan, as amended, will
become fully vested. At June 22, 2000, 556,982 shares of unvested restricted
stock and options to purchase 2,141,406 shares of common stock were outstanding.
At the effective time of the merger, each share of restricted stock will convert
into the right to receive a cash payment of $43.50. Holders of restricted stock
also will participate in the distribution of Harbor Global common shares. As
soon as practicable after the merger, each holder of an unexercised option for
Pioneer common stock will receive a cash payment equal to the excess of $43.50
over the per share exercise price of such option, multiplied by the number of
shares subject to the option. Unless holders of options exercise their options
prior to the effective time of the merger, they will not participate in the
distribution of Harbor Global common shares.

INTERESTS OF EXECUTIVE OFFICERS AND DIRECTORS OF PIONEER IN THE MERGER (PAGE 47)

In considering the recommendation of the Pioneer board of directors, you should
be aware that executive officers and certain directors of Pioneer

                                        8
<PAGE>   13

have interests in the merger that differ from the interests of other
stockholders. These include:

     - Certain executive officers and directors of Pioneer have entered into
       retention agreements which will entitle them to payments if their
       employment is terminated or their duties are materially changed following
       the merger. It is expected that certain of these officers and directors
       will be entitled to receive severance benefits as a consequence of the
       merger and related transactions.

     - John F. Cogan, Jr., Pioneer's president, chief executive officer and
       chairman of the board, will receive a special bonus payment of $700,000
       from Pioneer if we complete the merger.

     - While not a condition to the merger, we anticipate that some of our
       executive officers will be offered employment with UniCredito and its
       subsidiaries after the merger. In particular, it is anticipated that Mr.
       Cogan will become deputy chairman of UniCredito's global asset management
       business and non-executive chairman of UniCredito's U.S. asset management
       operations and David D. Tripple will become chief executive officer of
       UniCredito's U.S. asset management operations.

     - Pioneer's executive officers and directors beneficially own a total of
       5,488,879 shares of Pioneer common stock. Of these shares, 73,003 shares
       of restricted stock and 893,700 shares subject to options will vest on an
       accelerated basis due to the merger.

     - Certain officers of Pioneer will become executive officers of Harbor
       Global. In addition, certain of these officers will own and operate
       Calypso Management LLC, which has agreed to manage the liquidation of
       Harbor Global and operate Harbor Global's assets until they are
       liquidated. Harbor Global has agreed to pay Calypso a portion of the
       proceeds from the liquidation of it assets available for distributions as
       compensation for Calypso's services. See "Certain Relationships and
       Related Transactions" in the Harbor Global information statement attached
       as Annex B to this proxy statement.

     - The members of our board of directors who are also members of the special
       committee will be directors of Harbor Global.

     - Pioneer officers and directors have customary rights to indemnification
       against liabilities.

In considering the fairness of the merger to Pioneer stockholders, the board of
directors and the special committee took these potential conflicts of interest
into account.

OPINIONS OF MERRILL LYNCH & CO. AND SALOMON SMITH BARNEY INC. (PAGE 29)

In deciding to approve the merger, the special committee and the Pioneer board
of directors received opinions from Merrill Lynch & Co. and Salomon Smith Barney
Inc. that the aggregate consideration to be received by the Pioneer stockholders
in the merger and the distribution of shares of Harbor Global is fair, from a
financial point of view, to the Pioneer stockholders. In their analyses, the
investment banks made numerous assumptions with respect to Pioneer and Harbor
Global. Such assumptions and estimates contained in their analyses, and the
valuation ranges resulting from their particular analyses, are not necessarily
indicative of actual values or predictive of future results or values, which may
be significantly more or less favorable than those suggested by such analyses.
The opinions of the investment banks are dated as of the date of this proxy
statement and opine as to the fairness as of that date only. The investment
banks are not obligated to update their opinions. Events could occur prior to
the date of the special meeting which could result in a different valuation or
conclusion if the opinions were reissued on that date. Copies of the fairness
opinions of the investment banks are attached as Annex C and Annex D to this
proxy statement.

FEES AND EXPENSES (PAGE 60)

UniCredito estimates that the total amount of funds required to pay the merger
consideration to Pioneer stockholders will be approximately $1.2 billion. In
addition, UniCredito and Pioneer estimate that there will be approximately $--
in filing, legal, accounting and other fees and expenses payable by UniCredito
and Pioneer in connection

                                        9
<PAGE>   14

with the merger and the distribution of Harbor Global common shares.

UniCredito has advised Pioneer that UniCredito currently has available from
operations the funds necessary to complete the proposed merger.

CONDITIONS TO THE MERGER (PAGE 63)

The completion of the merger depends on a number of conditions, including:

     - the approval of Pioneer stockholders pursuant to this proxy statement;

     - the expiration or termination of all applicable waiting periods, and any
       extensions of these periods, under antitrust regulations including those
       of the Council of the European Union;

     - the approval of the Bank of Italy;

     - the approval of the merger or qualification of UniCredito by the Board of
       Governors of the Federal Reserve System;

     - approval of new management contracts, on terms similar to those in the
       existing management contracts, between Pioneer Investment Management,
       Inc. and the United States investment companies in the Pioneer Family of
       Funds representing at least 92.5% of the total assets in the Pioneer
       Family of Funds;

     - the exercise by holders of not more than 15% of the outstanding shares of
       Pioneer common stock of appraisal rights;

     - the distribution of the outstanding common shares of Harbor Global to
       Pioneer's stockholders; and

     - other customary contractual conditions specified in the merger agreement.

NO SOLICITATION BY PIONEER (PAGE 62)

With certain exceptions and subject to the fiduciary obligations of Pioneer's
board of directors to recommend any superior proposal to Pioneer stockholders,
Pioneer has agreed that neither it nor any of its subsidiaries will:

     - solicit, initiate or encourage any proposal that might lead to an
       alternative transaction pursuant to which a third party acquires more
       than 20% of the outstanding shares of Pioneer common stock or Pioneer
       assets having a total book value of more than 20% of all Pioneer assets;

     - engage in negotiations or discussions concerning, or provide any
       non-public information to any person relating to, any such acquisition of
       Pioneer common stock or assets; or

     - agree to recommend any such acquisition of Pioneer common stock or assets
       to the Pioneer stockholders.

Pioneer has agreed further to cause each of its officers, directors, employees,
financial advisors, representatives and agents, as well as the officers,
directors, employees, financial advisors, representatives and agents of its
subsidiaries, not to take any of these actions.

TERMINATION OF THE MERGER AGREEMENT (PAGE 64)

Pioneer and UniCredito mutually can agree to terminate the merger agreement
without completing the merger, and either Pioneer or UniCredito can terminate
the merger agreement upon the occurrence of a number of events, including:

     - the other party breaches representations, warranties or covenants in the
       merger agreement which result in the conditions to closing not being
       satisfied and fails to exercise reasonable efforts to cure such breach;

     - the merger is not completed by February 15, 2001; or

     - Pioneer stockholders do not approve the merger.

In addition, if our board of directors exercises its fiduciary obligation to
recommend another offer, does not recommend against a tender offer or if the
stockholders accept a tender offer, UniCredito may terminate the merger
agreement.

                                       10
<PAGE>   15

If the merger agreement is terminated under certain circumstances, either
Pioneer or UniCredito may be required to pay the other party's costs and
expenses incurred in connection with the merger and the other transactions
contemplated by the merger agreement. In addition, if the merger agreement is
terminated because the Pioneer board of directors fails to support the merger or
the Pioneer stockholders fail to approve the merger and Pioneer enters into a
subsequent transaction within 18 months with respect to a sale of Pioneer,
UniCredito would be entitled to a payment from Pioneer of $37,500,000.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES (PAGE 51)

It is generally anticipated that each stockholder will recognize capital gain or
loss equal, in each case, to the difference between the cash proceeds received
pursuant to the merger and the value of the shares of Harbor Global distributed
in connection with the merger and the stockholder's adjusted tax basis in the
Pioneer common stock surrendered in exchange therefor. However, if the receipt
of Harbor Global common shares is treated for tax purposes as a separate
transaction, it would be a distribution taxable as an ordinary income dividend
to the extent of our current or accumulated earnings and profits, including
earnings and profits resulting from the distribution of such shares.

In addition, because Harbor Global intends to be treated as a partnership for
United States federal income tax purposes, you will generally recognize a
proportionate share of Harbor Global's income, gain, loss and credit, including
gain or loss from the sale of Harbor Global subsidiaries, determined in
accordance with your interest in Harbor Global. You may also be required to
recognize a proportionate share of the income earned by any Harbor Global
subsidiary that is classified as a foreign personal holding company or a passive
foreign investment company. You are urged to consider whether making a qualified
electing fund election with respect to each passive foreign investment company
would be beneficial to you.

BECAUSE CERTAIN TAX CONSEQUENCES OF THE MERGER ARE COMPLEX AND THE DISTRIBUTION
MAY VARY DEPENDING ON THE PARTICULAR CIRCUMSTANCES OF EACH STOCKHOLDER, WE
RECOMMEND THAT HOLDERS OF PIONEER COMMON STOCK CONSULT THEIR TAX ADVISORS
CONCERNING THE FEDERAL (AND ANY STATE, LOCAL AND FOREIGN) TAX CONSEQUENCES OF
THE MERGER AND THE DISTRIBUTION IN THEIR PARTICULAR CIRCUMSTANCES.

PIONEER STOCKHOLDER APPRAISAL RIGHTS (PAGE 57)

Pioneer stockholders are entitled under Delaware law to appraisal rights in
connection with the merger. If you exercise appraisal rights and follow the
specified procedures, you can receive the judicially determined fair value of
your shares of Pioneer common stock rather than $43.50. The judicially
determined fair value may be more or less than $43.50 per share. To exercise
appraisal rights, a Pioneer stockholder must satisfy the following criteria:

     - provide written notice of his, her, or its intention to exercise
       appraisal rights before the vote is taken at the special meeting, even if
       the Pioneer stockholder is not entitled to vote at the Pioneer special
       meeting;

     - vote against approval of the merger agreement and the merger or abstain
       from voting; and

     - comply with other procedures of the Delaware General Corporation Law,
       including Section 262.

A copy of Section 262 of the Delaware General Corporation Law is attached to
this proxy statement as Annex E.

                           FORWARD LOOKING STATEMENTS

     This proxy statement and the documents that are incorporated by reference
into this proxy statement include statements that are subject to risks and
uncertainties and are based upon the beliefs and assumptions of our management.
The Private Securities Litigation Reform Act of 1995 provides a "safe harbor"
for these forward-looking statements. For this purpose, a forward-looking
statement is any statement that is not a statement of historical fact.
Forward-looking statements include those about our plans or strategies for our
domestic and international financial services and global investment management
businesses, our anticipated revenue growth, changes we expect in the amount or
composition of our assets under management, our anticipated expenses, our
liquidity and capital resources and our expectations about market conditions.
You can identify forward-looking statements by the words "may," "believes,"
"anticipates," "plans," "expects," "estimates" and similar expressions. Our
forward-looking statements are based on currently available information and
management's expectations of future results but necessarily involve certain
assumptions. Forward-looking statements include the information concerning
possible and assumed future results of our operations set forth:

     - under "Questions and Answers About the Merger," "Summary" and "The
       Merger" in this proxy statement;

     - under "Business" and "Management's Discussion and Analysis of Financial
       Condition and Results of Operations" in our Annual Report on Form 10-K
       for the year ended December 31, 1999, that is incorporated by reference
       into this proxy statement; and

     - under "Management's Discussion and Analysis of Financial Condition and
       Results of Operations" in our Quarterly Report on Form 10-Q for the
       fiscal quarter ended March 31, 2000, that is incorporated by reference
       into this proxy statement.

     Forward-looking statements are not guarantees of performance. They involve
risks, uncertainties and assumptions. The future results and stockholder values
of Pioneer may differ materially from those expressed in the forward-looking
statements. Many of the important factors that will determine these results and
values are beyond our ability to control or predict. You should not put undue
reliance on any forward-looking statements. We caution readers that our
assumptions involve substantial risks and uncertainties. Consequently, any
forward-looking statement could turn out to be wrong.

     You should understand that the following important factors, in addition to
those discussed elsewhere in the documents which are incorporated by reference
into this proxy statement, could affect the future results of Pioneer and could
cause results to differ materially from those expressed in such forward-looking
statements:

     - competitive pressures among financial services companies may increase
       significantly;

     - general economic conditions, either internationally or nationally, or the
       performance of the domestic or international securities markets, may be
       less favorable than expected; and

     - legislative or regulatory changes may adversely affect the businesses in
       which Pioneer is engaged.

                          THE PIONEER SPECIAL MEETING

     We are furnishing this proxy statement to holders of Pioneer common stock
in connection with the solicitation of proxies by the Pioneer board of directors
for use at the special meeting of the Pioneer stockholders to be held on August
--, 2000, and any adjournment or postponement of the meeting.

     We are first furnishing this proxy statement to the Pioneer stockholders on
or about July --, 2000.

DATE, TIME AND PLACE

     The special meeting will be held on August --, 2000 at --, local time, at
the offices of Hale and Dorr LLP, 26th floor, 60 State Street, Boston,
Massachusetts 02109.

MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING

     At the special meeting of the Pioneer stockholders and any adjournment or
postponement of the special meeting, we will ask Pioneer stockholders:

     - to consider and vote upon the adoption and approval of the merger
       agreement and the merger; and

     - to transact such other business as may properly come before the special
       meeting.

RECORD DATE

     Only stockholders of record of Pioneer common stock at the close of
business on --, 2000 are entitled to notice of and to vote at the special
meeting.

VOTING AND REVOCATION OF PROXIES

     We request that the Pioneer stockholders complete, date and sign the
accompanying proxy and promptly return it in the accompanying postage-paid
envelope or otherwise mail it to Pioneer. You may also vote by calling -- toll
free and voting by telephone or visit www.eproxy.com/-- and vote on the
Internet. Brokers holding shares in "street name" may vote the shares only if
the beneficial stockholder provides instructions on how to vote. Brokers will
provide beneficial owners instructions on how to direct the brokers to vote the
shares. All properly executed proxies that Pioneer receives prior to the vote at
the special meeting that are not revoked will be voted in accordance with the
instructions indicated on the proxies. If no direction is indicated, the proxies
will be voted to adopt and approve the merger agreement and the merger.

     The Pioneer board of directors does not currently intend to bring any other
business before the special meeting and, so far as the Pioneer board of
directors knows, no other matters are to be brought before the special meeting.
If other business properly comes before the special meeting or any postponement
or adjournment, the proxies will be voted in accordance with the judgment of
Pioneer's management.

     A stockholder may revoke his, her or its proxy at any time prior to its use
by:

     - delivering to the secretary of Pioneer a signed notice of revocation or a
       later-dated, signed proxy; or

     - attending the special meeting and voting in person.

     Attendance at the special meeting does not in itself constitute the
revocation of a proxy.

VOTE REQUIRED

     As of the close of business on --, 2000, the record date, there were --
shares of Pioneer common stock outstanding and entitled to vote. The
stockholders holding a majority of the outstanding shares of Pioneer common
stock must adopt and approve the merger agreement and the merger. The
stockholders holding a majority of the shares of Pioneer common stock entitled
to vote and that are present or represented by proxy at the Pioneer meeting must
approve the grant to the Pioneer board of directors of

                                       16
<PAGE>   21

the discretionary authority to adjourn the special meeting to solicit additional
votes. Pioneer stockholders have one vote per share of Pioneer common stock
owned on the record date.

     As of May 31, 2000, the directors and executive officers of Pioneer
beneficially owned an aggregate of 5,488,879 shares of Pioneer common stock
(including shares of restricted stock and shares subject to options) or
approximately 20.06% of the shares of Pioneer common stock outstanding on that
date. Under a voting agreement attached as Annex F to this proxy statement,
certain officers of Pioneer have agreed to vote all of the shares of Pioneer
common stock they beneficially own or over which they exercise voting control in
favor of the merger agreement and the merger. As of May 31, 2000, [THE DIRECTORS
AND EXECUTIVE OFFICERS OF UNICREDITO DID NOT OWN ANY SHARES OF PIONEER COMMON
STOCK.] See "The Merger -- Interests of Executive Officers and Directors of
Pioneer in the Merger."

QUORUM; ABSTENTIONS AND BROKER NON-VOTES

     The required quorum for the transaction of business at the special meeting
is a majority of the shares of Pioneer common stock issued and outstanding on
the record date. Abstentions and broker non-votes each will be included in
determining the number of shares present and voting at the special meeting for
the purpose of determining the presence of a quorum. Because adoption and
approval of the merger agreement and the merger requires the affirmative vote of
a majority of the outstanding shares of Pioneer common stock entitled to vote,
abstentions and broker non-votes will have the same effect as votes against
adoption and approval of the merger agreement and the merger. In addition, the
failure of a Pioneer stockholder to return a proxy or vote in person will have
the effect of a vote against the adoption and approval of the merger agreement
and the merger. Broker non-votes will not be included in the vote totals and
will have no effect on the outcome of the vote on the proposal to grant the
Pioneer board of directors the discretionary authority to adjourn the special
meeting. Abstentions, however, will have the same effect as a vote against these
proposals. Brokers holding shares for a beneficial owner cannot vote on the
actions proposed in this proxy statement without the beneficial owner's specific
instructions. Accordingly, Pioneer stockholders are urged to return the enclosed
proxy card marked to indicate their vote.

SOLICITATION OF PROXIES AND EXPENSES

     Pioneer has retained the services of D.F. King & Co., Inc. to assist in the
solicitation of proxies from its stockholders. The fees to be paid to D.F. King
& Co., Inc. for its services by Pioneer are expected to be approximately $7,500,
plus its expenses.

     In addition to solicitation by mail, the directors, officers and employees
of Pioneer may solicit proxies from Pioneer's stockholders by telephone,
facsimile, e-mail or in person. Brokerage houses, nominees, fiduciaries and
other custodians will be requested to forward soliciting materials to beneficial
owners and will be reimbursed by Pioneer for their reasonable expenses incurred
in sending proxy materials to beneficial owners.

RECOMMENDATION OF THE PIONEER BOARD OF DIRECTORS AND SPECIAL COMMITTEE

     The Pioneer board of directors and a special committee of the board of
directors have determined that the merger agreement and the merger are
advisable, fair to, and in the best interests of, Pioneer's stockholders.
Accordingly, the Pioneer board of directors and the special committee have each
unanimously approved the merger agreement and unanimously recommended that the
Pioneer stockholders vote for approval and adoption of the merger agreement and
the merger. See "The Merger -- Background to the Merger."

     In considering the recommendation of the Pioneer board of directors and the
special committee, the Pioneer stockholders should be aware that Pioneer's
executive officers and certain directors have interests in the merger that are
different from, or in addition to, those of Pioneer's other stockholders. See
"The Merger -- Interests of Executive Officers and Directors of Pioneer in the
Merger."

     THE MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING ARE OF GREAT IMPORTANCE
TO THE PIONEER STOCKHOLDERS. ACCORDINGLY, PIONEER STOCKHOLDERS ARE URGED TO READ
AND CAREFULLY CONSIDER THE INFORMATION PRESENTED IN THIS PROXY STATEMENT, AND TO
COMPLETE, DATE, SIGN AND PROMPTLY RETURN THE ENCLOSED PROXY IN THE ENCLOSED

Italy, and its shares trade on the Milan Stock Exchange. Now the holder of eight
major Italian banks, UniCredito is Italy's largest banking group based on market
capitalization and the 18th largest in Europe in terms of total assets.
UniCredito was formed in 1998 by the merger between Credito Italiano S.p.A., one
of Italy's major banks, and Unicredito S.p.A., an Italian bank holding company.
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 group of subsidiaries, branded EuroPlus, is

                                   THE MERGER

OVERVIEW OF THE MERGER

     The merger provides for the acquisition of Pioneer's global investment
management business by UniCredito. To accomplish the acquisition, Pioneer will
be merged with a wholly-owned subsidiary of UniCredito, with Pioneer as the
surviving corporation. In the merger, each outstanding share of Pioneer common
stock, other than shares held by stockholders who perfect appraisal rights, will
convert into the right to receive $43.50 in cash, and UniCredito will be issued
the entire equity interest in the corporation surviving the merger. Pioneer will
distribute to its stockholders of record immediately prior to the effective time
of the merger, all of its common shares of Harbor Global Company Ltd. Harbor
Global is a newly-formed Bermuda subsidiary of Pioneer to which certain of
Pioneer's businesses and assets will be transferred prior to the effective time
of the merger. This distribution will permit UniCredito to acquire only the
investment management portion of Pioneer's operations that it intends to conduct
in the future and will permit holders of Pioneer common stock to be able to
receive the proceeds from the liquidation of the businesses and assets
transferred to Harbor Global, net of expenses and other liabilities, within a
limited period of time.

     While UniCredito is expected to merge a wholly-owned subsidiary into
Pioneer, UniCredito may elect instead to merge Pioneer into a wholly-owned
subsidiary of UniCredito. Under the merger agreement, Pioneer has also agreed,
if requested by UniCredito, to negotiate in good faith to sell to UniCredito
certain assets of Pioneer's global investment management business in a
transaction separate from the merger. Pioneer is under no obligation to agree to
such a sale. No matter what acquisition structure UniCredito elects, each share
of Pioneer common stock, other than shares held by stockholders who perfect
appraisal rights, will convert into the right to receive a cash payment of
$43.50.

BACKGROUND TO THE MERGER

     Strategic Review.  Over the last few years, Pioneer's senior management and
its board of directors have engaged in an ongoing strategic review of Pioneer's
global businesses. These reviews led to two primary conclusions. First, the
investment management industry, particularly in the United States, is undergoing
rapid change and becoming increasingly competitive, and significant capital
resources would be necessary to address adequately this changing competitive
landscape. Second, Pioneer's non-investment management businesses have generated
significant losses and earnings volatility and have hurt overall stock
performance. In response to these conclusions, Pioneer embarked in late 1998 on
a restructuring that was designed to refocus management on Pioneer's core
competency, investment management, and to ensure that adequate resources were
available to address the changing nature of the investment management industry.
As part of this process, Pioneer committed to divest its natural resource
businesses, more specifically timber and gold. These strategic efforts continued
throughout 1999 and into 2000.

     As part of the ongoing strategic review process, Pioneer's board of
directors, on February 10, 2000, engaged Merrill Lynch & Co. and Salomon Smith
Barney Inc. to conduct an analysis of Pioneer's businesses, including U.S.
investment management operations, international financial services and the
global investment segments, and to assist the board and management in evaluating
strategic alternatives. Over the course of the next three weeks, representatives
of Merrill Lynch and Salomon Smith Barney conducted extensive due diligence
meetings with members of Pioneer's senior management. In addition, the
investment banks reviewed all of Pioneer's businesses, historical financial
statements, budgets, financial projections and business plans and conducted
extensive peer group analyses to understand better the competitive environment
in which Pioneer operates.

     On March 2, 2000, the board of directors along with members of Pioneer
senior management and its legal counsel met with representatives of Merrill
Lynch and Salomon Smith Barney to review the results of their engagements. The
investment banks concurred with the assessment that the financial services

                                       21
<PAGE>   26

industry as a whole, and more particularly the investment management segment of
that industry, is becoming increasingly competitive. Concerns over slower
earnings growth, customer retention, and control over distribution and its
increasing cost are the driving forces behind these competitive pressures. The
response to these pressures is at an early stage; however, it is likely to lead
to an industry that is increasingly dominated by large, globally operated
financial institutions that have the resources necessary to compete on a global
basis. The investment banks noted that Pioneer is not immune to these
competitive pressures despite its long-standing and strong investment management
brand in the United States and in Germany, its established reputation as a value
manager, its strong, well-diversified distribution system in the United States
and its well positioned opportunity to capture market share in the emerging
economies of Central and Eastern Europe. The size, retail focus and distribution
strength of Pioneer's investment management business are, however, extremely
attractive to many types of strategic partners. The investment banks also
believed that Pioneer's non-core businesses have depressed earnings, constrained
capital resources, hurt valuations and limited the company's ability to attract
analyst coverage because of the significant diversity in businesses.

     During the meeting on March 2, 2000, the investment banks also reviewed
with the board of directors the strategic alternatives available to Pioneer. Due
to the continuing competitive pressures in the investment management industry
and Pioneer's lack of resources to address adequately these pressures, the
possibility of stockholder activism in response to Pioneer's depressed stock
price, and uncertainty associated with the timing of the company's articulated
strategy of disposing of its natural resource businesses, the board of directors
concluded that remaining an independent publicly traded company was not a
value-maximizing alternative for Pioneer's stockholders. The board also reviewed
with the investment banks whether Pioneer could acquire another asset manager
with complimentary capabilities and concluded that Pioneer lacked the financial
flexibility and time necessary to pursue this strategy. In addition, pursuing
this strategy still did not adequately address the continuing concerns regarding
Pioneer's non-investment management businesses. For the same reasons, the board
of directors, with the advice of the investment banks, determined that a joint
venture, leveraged or management buy-out, merger-of-equals or other strategic
partnering arrangements were not attractive strategies. Accordingly, the board
concluded that a sale of the company was the strategic alternative most likely
to permit Pioneer to continue to grow the franchise and to maximize stockholder
value. In this regard, the investment banks advised the board that they
anticipated that there would be significant interest in Pioneer's franchise and
that most of the likely acquirers were strategic in nature.

     As part of their review of Pioneer's strategic alternatives, the investment
banks advised the board of directors that a sale of Pioneer could be made more
difficult because certain of Pioneer's assets are in non-investment management
businesses and/or are involved in high risk environments. The board of directors
concluded that, because a buyer was unlikely to emerge which would want to
purchase both the investment management businesses and the non-core operations,
Pioneer was unlikely to obtain fair value for the non-continuing businesses
through a sale of the company as a whole. Also, a sale of the investment
management businesses in a transaction not involving a merger would not be tax
advantageous to Pioneer's stockholders and Pioneer. The sale of the
non-continuing businesses prior to a sale of the investment management
businesses was not viewed as desirable since such a sale might cause substantial
delay in the sale of the investment management business and the market for the
gold, timber and Russian real estate assets was viewed as depressed and not
reflective of their long-term value.

     Because of these concerns, the board of directors determined that, while
prepared to sell the company as a whole, Pioneer would transfer the
non-investment management businesses to a newly formed subsidiary prior to any
sale of the company. Pioneer then could distribute the shares of this
subsidiary, Harbor Global, to its stockholders in connection with the sale of
the company. Harbor Global will liquidate these assets over a five year period,
which may, at the discretion of Harbor Global's board of directors, be extended
for up to three additional one year periods. Harbor Global will distribute any
proceeds, net of expenses and other liabilities, to its shareholders. This
arrangement would provide the potential for Pioneer stockholders to realize
additional value from the ultimate liquidation of these

                                       22
<PAGE>   27

assets within a reasonable time frame while permitting the sale of Pioneer's
primary businesses to proceed expeditiously.

     Establishment of the Special Committee.  In light of the potential
conflicts of interest of members of the board of directors who are also members
of management (see "The Merger -- Interests of Executive Officers and Directors
of Pioneer in the Merger"), the board of directors at the March 2, 2000 meeting
established a special committee of the board, which was given authority to
supervise the solicitation of offers for the purchase of Pioneer and to make a
recommendation to the board of directors and stockholders with respect to any
bids that were received. The members of the special committee are John D. Curtin
Jr., W. Reid Sanders and John H. Valentine. None of the members of the special
committee is an officer of Pioneer or has any interest in the sale of Pioneer
that differs from the interests of stockholders. The members of the special
committee received a fee of $5,000 for serving on the special committee. The
special committee was authorized to retain its own advisors; however, in light
of the work that the investment banks retained by the board of directors had
performed to that date, the special committee determined to continue to use the
same investment banks in connection with its evaluation of any bids that were
received.

     The Auction Process.  After considering the recommendations of Merrill
Lynch and Salomon Smith Barney, the board of directors and the special committee
at the meeting on March 2, 2000 authorized the investment banks to solicit
offers to purchase Pioneer. On March 17, 2000, the special committee along with
members of Pioneer's management met with the investment banks to review the
status of the solicitation process and to consider structuring issues relating
to the distribution of the Harbor Global common shares to Pioneer stockholders.
In late March and early April 2000, the investment banks contacted over 80
financial institutions and investment advisors to determine their interest in
acquiring Pioneer. Of those companies, over 50 companies entered into
confidentiality agreements with the company and received information with
respect to Pioneer's investment management business.

     After receiving preliminary, non-binding indications of interest from 16
potential acquirors, the investment banks reviewed the preliminary bids with the
special committee, certain members of management and the company's legal counsel
at a meeting held at the offices of the company on April 13, 2000. The
investment banks provided an evaluation of the preliminary bids and recommended
that the next step should be to invite a limited number of bidders to conduct a
more thorough due diligence review of Pioneer. Based upon the investment banks'
recommendations as to the number and identity of the potential purchasers that
should be invited to conduct due diligence, the special committee invited eight
potential purchasers to conduct more extensive, on-site due diligence. The
selection was based principally on the value of the bidders' preliminary
indications of interest. At the meeting, the special committee also considered
the acceptability of the distribution of Harbor Global common shares to Pioneer
stockholders.

     During the period from April 17, 2000 through May 5, 2000, members of
Pioneer's management met on-site with representatives of the selected bidders,
their legal counsel and financial advisors. The selected bidders were directed
to submit final, binding bids by May 9, 2000. The potential bidders were also
provided with a draft merger agreement and were directed to submit any comments
on that agreement with their bids.

     After receiving the bids on May 9, 2000, the special committee held a
meeting at the offices of Hale and Dorr LLP, in Boston, Massachusetts, legal
counsel to Pioneer, on the evening of May 10, 2000. All members of the special
committee were present at that meeting. Representatives of Hale and Dorr LLP
reviewed with the members of the special committee their fiduciary
responsibilities in connection with the potential sale. The investment banks
then reviewed with the special committee the determination to pursue a sale of
the company, the financial terms of each bid and the financial terms of the
various offers. Hale and Dorr LLP then reviewed the other terms of the offers,
including changes that each bidder proposed to make to the draft merger
agreement and any regulatory or other conditions to the offers. Hale and Dorr
LLP also reviewed the issues in the merger agreement that would need to be
negotiated with UniCredito. The members of the special committee also asked
representatives of Hale and Dorr LLP and Pioneer's

                                       23
<PAGE>   28

management to confirm that the bid by UniCredito did not provide for any special
financial arrangements for Mr. Cogan, Mr. Tripple or other members of senior
management. Based upon such review, the special committee recommended that the
board authorize management and Pioneer's legal and financial advisors to
negotiate a definitive merger agreement with UniCredito.

     Immediately following the meeting of the special committee on May 10, 2000,
the entire board of directors held a meeting at the offices of Hale and Dorr
LLP. All members of the board of directors were present at the meeting in person
or by phone. Representatives of the investment banks, Hale and Dorr LLP and
Pioneer's management also participated in the meeting. The members of the
special committee advised the board of directors that they had reviewed the bids
and determined that the offer by UniCredito was the most favorable to Pioneer's
stockholders. The special committee recommended that the management of Pioneer
be directed to conduct negotiations of a definitive merger agreement with
representatives of UniCredito. The investment banks reviewed the terms of the
UniCredito offer with the board of directors. Hale and Dorr LLP discussed the
contractual issues that required negotiation, UniCredito's proposed conditions
to closing, including the required regulatory approvals, and the non-financial
terms of the other offers. Hale and Dorr LLP also reviewed the board of
directors' fiduciary obligations in the context of an auction of Pioneer. Hale
and Dorr LLP noted that the proposed form of merger agreement permitted the
board of directors to accept an alternative offer if it was more favorable to
the company's stockholders, provided that UniCredito receive a $37.5 million
break-up fee from Pioneer. Based upon such review and the recommendation of a
special committee, the board of directors authorized management and Pioneer's
legal and financial advisors to negotiate a definitive merger agreement with
UniCredito.

     During the period from May 11, 2000 through May 14, 2000, representatives
of Pioneer and its legal and financial advisors met with representatives of
UniCredito and its legal and financial advisors to negotiate the terms of a
definitive merger agreement. These negotiations were completed on May 14, 2000.

     A telephonic meeting of the special committee was held at noon on May 14,
2000. All members of the special committee were present at the meeting, as were
representatives of the investment banks and Hale and Dorr LLP. Hale and Dorr LLP
reported on the progress of the negotiations and that all open issues discussed
with the special committee on May 10, 2000 had been resolved to the satisfaction
of Pioneer's management. No material terms of the transaction had changed in a
manner adverse to Pioneer. The differences between the proposed contract and the
final agreement were reviewed. Merrill Lynch then reviewed again the previous
analysis of Pioneer's strategic alternatives, the financial and other terms of
the offer and the terms of the competing bids. Merrill Lynch also delivered its
oral opinion that the terms of the merger are fair from a financial point of
view to Pioneer's stockholders. Salomon Smith Barney separately discussed the
merger and provided its oral opinion as to the fairness, from a financial point
of view, of the consideration to be paid in the merger. See "The
Merger -- Opinions of Merrill Lynch and Salomon Smith Barney." Based upon such
analysis, the special committee voted to recommend the approval of the merger
agreement and the merger with UniCredito to the board of directors and the
Pioneer stockholders.

     A telephonic meeting of the entire board of directors was held on May 14,
2000 immediately following the meeting of the special committee. All of the
members of the board of directors were present at the meeting in person or by
telephone, as were representatives of the investment banks, Hale and Dorr LLP
and Pioneer's management. The special committee advised the board of directors
of its recommendation. Hale and Dorr LLP and the investment banks then reviewed
the terms of the merger agreement for the board of directors. Each financial
advisor orally advised the board of directors of its opinion that the
consideration to be paid in the merger is fair to Pioneer's stockholders from a
financial point of view. The board of directors then unanimously determined that
entering into the merger agreement was in the best interests of Pioneer and its
stockholders and voted to authorize Pioneer to enter into the merger agreement
and to recommend the merger to Pioneer's stockholders.

                                       24
<PAGE>   29

     On the afternoon of May 14, 2000, Pioneer and UniCredito entered into the
merger agreement. Pioneer issued a press release announcing the proposed merger
with UniCredito prior to the opening of trading of its common stock on May 15,
2000.

     Lens Investment Management, LLC.  On February 2, 2000, Southeastern Asset
Management, Inc., the Pioneer's largest stockholder, filed a Schedule 13D
reporting that it had engaged in an unsolicited conversation with a third party
regarding the potential sale of Pioneer. Previously, Southeastern had reported
its ownership of Pioneer common stock on Schedule 13G as a passive investment.
On February 15, 2000, Pioneer received official notification from Lens
Investment Management, LLC that it intended to nominate four nominees for
election to Pioneer's board of directors at Pioneer's annual meeting in May
2000. The purpose of the alternative slate of directors was to proceed with a
sale of the company. On February 23, 2000, Lens filed with the Securities and
Exchange Commission a preliminary proxy statement in which it indicated that it
would be soliciting proxies for its alternative slate of directors at Pioneer's
annual meeting. Lens stated in its proxy statement that the total value of
Pioneer's equity may exceed $28 per share and that the proceeds from a sale of
Pioneer's investment management business could exceed $38 per share. On March
17, 2000, Lens notified Pioneer that rather than nominate four nominees for
election to Pioneer's board, it now proposed to nominate five nominees. On March
22, 2000, Lens filed another preliminary proxy statement reflecting the increase
in the number of nominees. Lens filed its definitive proxy statement on April
10, 2000. In the definitive proxy statement Lens reiterated its intent to
proceed with a sale of the company if its nominees were elected. Lens also
stated that the total value of Pioneer's equity could be more than $29 per share
and as much as $42 per share. At the annual meeting of stockholders, which took
place shortly after the announcement of the terms of the merger, Lens voted its
shares in favor of the current management.

REASONS FOR THE MERGER

     As discussed above, in February 2000, the board of directors began an
evaluation of Pioneer's strategic alternatives that resulted in the execution of
the merger agreement. In reaching their determination to approve the merger
agreement and recommend that Pioneer stockholders vote to adopt and approve the
merger agreement and the merger, the special committee and the board of
directors considered the following material factors:

     - The board of directors retained Merrill Lynch and Salomon Smith Barney to
       review Pioneer's strategic alternatives. Those reviews confirmed
       management's belief that the nature of the investment management business
       had fundamentally changed in recent years, giving companies with
       substantial amounts of assets under management and global operations a
       significant competitive advantage over smaller investment advisers. Based
       upon their reviews, the board of directors concluded that Pioneer would
       require a substantially more significant presence to continue to compete
       in the long term in the mutual fund industry and that Pioneer's principal
       business is likely to be increasingly dominated by large, globally
       operating financial institutions. Because the significant capital
       resources necessary to develop such a franchise were not available to
       Pioneer, the board of directors determined to pursue strategic
       alternatives. Pioneer's management concluded, based upon the investment
       banks' analyses and other factors, that long-term success in the
       investment management business required that Pioneer experience
       significant domestic and global growth. Due in part to the significant
       costs required to establish a substantial international presence, the
       board of directors concluded that it is unlikely that Pioneer currently
       has the financial resources to undertake such an expansion, whether
       through internal growth or acquisitions. The board of directors did not
       believe that Pioneer could achieve sustainable domestic and international
       growth unless it became part of a larger financial institution. Without
       such growth, Pioneer risks a continued loss of market share to larger
       competitors and a corresponding reduction in assets under management.

                                       25

     - The financial condition and results of operations of Pioneer, including
       the losses that it has incurred during the past two years, and the
       prospects of both Pioneer's investment management operations and
       non-continuing businesses.

     - A review of the possible alternatives to the merger, including:

           - The prospect and risks of continuing operations as they are
             presently conducted including the challenges of competing with
             large, global financial services companies;

           - The possibility that the future performance of our investment
             management business could result in a lower valuation of Pioneer;

           - The sale of the non-core businesses and the continuation of the
             investment management business as a separate business;

           - The acquisition by Pioneer of other investment management
             businesses; and

           - The establishment of a joint venture, leveraged or management
             buy-out, a merger-of-equals or other strategic partnering
             arrangement.

     - The equity markets in the second half of the 1990s have favored
       investment advisers which follow growth and index investment strategies.
       Pioneer's traditional value investment strategy has generally provided
       returns during the past five years below the returns achieved by the
       general market indices and investment advisers focusing on technology
       weighed growth strategies. These trends, which have continued this year,
       have adversely affected Pioneer's ability to attract and retain assets in
       its funds. The net assets under Pioneer's management in U.S. open-end
       investment companies were approximately $22.0 billion at December 31,
       1998, $23.4 billion at December 31, 1999, and $23.2 billion at March 31,
       2000. This represents an average annual growth in assets under management
       of 7.7% since December 31, 1997. During that same period, the Standard &
       Poor's 500 Index has increased at an average annual rate of 21.3%. During
       1999, Pioneer experienced net redemptions (the amount by which
       redemptions by stockholders in Pioneer's funds exceed new sales of our
       funds) equivalent to approximately $1.0 billion of assets under
       management in our U.S. funds. Prior to 1999, Pioneer had not experienced
       net redemptions since 1992. We continued to experience net redemptions
       during the first half of 2000.

     - The price to be paid per share represents a 40% premium over the closing
       price of Pioneer common stock on May 12, 2000, the last trading day
       before our announcement of the terms of the merger agreement with
       UniCredito, a nearly 100% premium over the closing price on March 2,
       2000, the day prior to announcement that the board of directors had
       authorized the investment banks to actively explore strategic
       alternatives, including a possible sale of Pioneer, and a 159% premium
       over the closing price on February 10, 2000, the day before our
       announcement that we had retained investment banks to conduct a review of
       Pioneer's businesses and to assist the board of directors and management
       in evaluating strategic alternatives. We believe that if the merger is
       not completed, absent other factors, our stock price may revert back to
       its historical trading range. Given the long bull market in equity
       securities, we also believe that this is a favorable time to sell an
       investment advisory business.

     - The opinions of Merrill Lynch and Salomon Smith Barney that, as of the
       date of this proxy statement, and based upon and subject to the
       assumptions set forth in their opinions, the aggregate consideration to
       be received by Pioneer's stockholders in connection with the merger and
       the Harbor Global distribution, consisting of the cash consideration and
       the shares of Harbor Global, is fair to Pioneer's stockholders from a
       financial point of view.

     - The structure of the transaction is more likely to allow Pioneer
       stockholders to maximize the values from the liquidation of Pioneer's
       non-continuing businesses through the distribution of the shares of
       Harbor Global. While the board of directors considered the current value
       of such assets difficult to

                                       26
<PAGE>   31

       determine and dependent upon improvement in the market for such classes
       of assets, the distribution permits Pioneer's stockholders to benefit
       from any realization of the value of these assets.

     - The special committee and the board of directors considered that the
       auction process offered the best means of determining that UniCredito's
       offer was fair to Pioneer's stockholders and, together with the
       appointment of a special committee, provided for a process that was fair
       to Pioneer's stockholders.

     In view of the variety of factors considered in connection with the special
committee's and the board of directors' evaluation of the merger, neither the
special committee nor the board of directors attempted to assign any relative
weight to the forgoing factors. The recommendation of the special committee and
the board of directors is based upon the totality of the information presented
to and considered by them. However, the financial measures cited below under
"The Merger -- Opinions of Merrill Lynch and Salomon Smith Barney" and the
premium of $43.50 to the recent market prices of Pioneer's common stock were
noted as particularly favorable by the special committee and the board of
directors. The special committee and the board of directors considered, but did
not place particular emphasis upon, valuation, based upon book value, going
concern value or liquidation value, because the investment banks advised that
such measures are not an appropriate means of valuing an investment management
business.

RECOMMENDATION OF PIONEER'S BOARD OF DIRECTORS

     The special committee and Pioneer's entire board of directors have
unanimously concluded that the merger is fair to, and in the best interest of,
Pioneer's stockholders. Pioneer's board of directors and the special committee
unanimously recommend that the stockholders vote to adopt and approve the merger
agreement and the merger.

DISTRIBUTION OF HARBOR GLOBAL INTERESTS

     Pioneer currently owns or operates certain assets and businesses that
UniCredito does not wish to acquire. In order that UniCredito may acquire only
those portions of Pioneer's businesses that it wishes to purchase while
structuring the transaction as a merger and also to provide Pioneer's
stockholders with the potential to maximize the value of these other businesses,
Pioneer has established a Bermuda limited duration company, Harbor Global
Company Ltd. Pioneer's non-continuing businesses will be transferred to Harbor
Global prior to the effective time of the merger. Pioneer will distribute to its
stockholders of record immediately prior to the effective time of the merger all
of the common shares of Harbor Global. Each Pioneer stockholder as of the record
date of the distribution will receive one share of Harbor Global for every five
shares of Pioneer common stock. Fractional shares of Harbor Global will not be
distributed. Rather, Harbor Global's distribution agent will aggregate and seek
to sell fractional shares, and the aggregate net cash proceeds, if any, will be
distributed pro rata to Pioneer stockholders entitled to a fractional interest.
See Annex B.

     At the time of the distribution, Harbor Global's assets will consist
primarily of the following businesses and assets currently owned, operated or
owned by Pioneer:

     - real estate management and investment management operations in Russia;

     - Polish and Eastern European venture capital investment and management
       operations;

     - Polish and Eastern European real estate management operations;

     - timber harvesting and sales in Russia;

     - gold exploration operations in Russia;

                                       27
<PAGE>   32

     - the proceeds from the sale of Pioneer's gold mine in Ghana to Ashanti
       Goldfields Teberebie Limited (which proceeds will consist of $5 million
       in cash and a $13.8 million promissory note payable to Pioneer Goldfields
       II Limited, a wholly-owned subsidiary of Harbor Global); and

     - $25 million in cash.

     At the time of the distribution, Harbor Global's principal liabilities will
include:

     - the obligation to pay to Pioneer up to $5 million of the proceeds from
       the sale of the Teberebie gold mine if indemnification claims by Ashanti
       Goldfields are less than the aggregate proceeds from the sale of the
       mine;

     - indemnification obligations to Pioneer under a distribution agreement and
       a tax separation agreement between Pioneer and Harbor Global;

     - certain severance and retention payments payable to certain officers and
       employees of Harbor Global in connection with the termination of their
       employment with Pioneer or the continuation of their employment with
       Harbor Global subsidiaries; and

     - capital commitments to entities established by the Eastern European real
       estate business.

     The distribution of the shares of Harbor Global will be a taxable
transaction. See "The Merger -- Material United States Federal Income Tax
Consequences." We currently estimate that we will report for federal tax
purposes that the Harbor Global common shares received in the distribution will
have a value of approximately $-- - $-- with respect to each share of Pioneer
common stock held at the time of the merger (equating to a value of the Harbor
Global common shares of approximately $---$-- per share). However, the actual
value we ascribe to the Harbor Global common shares for federal tax purposes may
differ due, among other reasons, to changes in the value of Harbor Global's
assets between December 31, 1999 and the date of the distribution and the number
of shares of Pioneer common stock outstanding on the effective date of the
merger. We will provide you with information regarding the value of the Harbor
Global common shares you receive in the distribution. However, this information
is not binding on the Internal Revenue Service, which may assert a different
(and possibly higher) value for the Harbor Global common shares you receive.
Accordingly, there can be no assurance as to the exact amount of gain you may
recognize as a result of the merger and the distribution, in such a
circumstance. The value estimated for tax purposes is not necessarily indicative
of the price at which you may be able to sell Harbor Global common shares. It is
possible that no trading market for the Harbor Global common shares will
develop. The Harbor Global common shares are registered with the Securities and
Exchange Commission and are transferable. However, there is no current public
trading market for Harbor Global common shares, and they will not be listed on a
securities exchange or The Nasdaq Stock Market(R). Furthermore, Harbor Global
does not intend to take any actions to facilitate the development of an active
trading market. See Harbor Global's information statement attached as Annex B.

     Pioneer currently does not expect to distribute the shares of Harbor Global
unless the merger is approved and is expected to be completed.

     A copy of the information statement included in Harbor Global's
registration statement on Form 10 under the Securities Exchange Act of 1934 is
attached as Annex B to this proxy statement. It contains information regarding
Harbor Global, including Harbor Global's financial statements and risk factors.
You should read it carefully in considering whether to adopt and approve the
merger agreement and the merger.

OPINIONS OF MERRILL LYNCH AND SALOMON SMITH BARNEY

     Opinion of Merrill Lynch & Co.

     Merrill Lynch has acted as financial advisor to Pioneer in connection with
a review of Pioneer's strategic alternatives, the merger and the distribution of
common shares of Harbor Global and has assisted the Pioneer board of directors
in its examination of the fairness, from a financial point of view, of the
merger consideration and shares of Harbor Global to be received by Pioneer's
stockholders.

     On May 14, 2000, Merrill Lynch orally advised the special committee and the
Pioneer board of directors that, based upon and subject to the limitations of
its analyses, as of such date, the merger consideration was fair, from a
financial point of view, to the Pioneer stockholders. In connection with the
preparation of this proxy statement, Merrill Lynch rendered its opinion to the
effect that, based upon and subject to the considerations set forth in the
opinion, as of the date of this proxy statement, the aggregate consideration to
be received by the Pioneer stockholders in the merger and the distribution of
Harbor Global common shares is fair, from a financial point of view, to the
holders of Pioneer common stock.

     THE FULL TEXT OF MERRILL LYNCH'S OPINION, WHICH CONTAINS MANY OF THE
ASSUMPTIONS MERRILL LYNCH MADE, THE MATTERS IT CONSIDERED AND THE LIMITATIONS ON
THE REVIEW IT UNDERTOOK IN CONNECTION WITH ITS DELIVERY OF THIS OPINION, IS
INCLUDED AS ANNEX C AND IS INCORPORATED BY REFERENCE INTO THIS PROXY STATEMENT.
MERRILL LYNCH'S OPINION IS DIRECTED TO THE PIONEER BOARD OF DIRECTORS AND
ADDRESSES ONLY THE FAIRNESS OF THE CONSIDERATION FROM A FINANCIAL POINT OF VIEW.
IT DOES NOT ADDRESS ANY OTHER ASPECT OF THE MERGER OR THE DISTRIBUTION OF HARBOR
GLOBAL COMMON SHARES OR ANY RELATED TRANSACTIONS AND DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY PIONEER STOCKHOLDER AS TO HOW THAT HOLDER SHOULD VOTE AT
THE PIONEER SPECIAL MEETING. THE FOLLOWING SUMMARY OF MERRILL LYNCH'S OPINION
SET FORTH BELOW IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF
SUCH OPINION. STOCKHOLDERS ARE URGED TO READ THE MERRILL LYNCH OPINION CAREFULLY
AND IN ITS ENTIRETY.

     In connection with rendering its opinion of the same date as the date of
this proxy statement, Merrill Lynch, among other things:

     - reviewed certain publicly available information concerning Pioneer;

     - reviewed certain other financial information with respect to Pioneer,
       including financial forecasts relating to the business, earnings, cash
       flow, assets and prospects of Pioneer, that Pioneer provided to Merrill
       Lynch;

     - conducted discussions with members of senior management of Pioneer
       concerning the businesses and prospects of Pioneer;

     - reviewed certain publicly available information concerning the trading
       of, and the trading market for, Pioneer common stock;

     - compared the results of operations of Pioneer's global investment
       management business with those of certain other companies;

     - compared the financial terms of the merger with those of certain other
       transactions;

     - reviewed the results of the efforts of Merrill Lynch and Salomon Smith
       Barney to solicit proposals for an acquisition of Pioneer in its entirety
       or its global investment management business;

     - reviewed the merger agreement;

     - reviewed the terms of the distribution of shares of Harbor Global and
       drafts of the related distribution agreement and the tax separation
       agreement;

     - reviewed a letter regarding the solvency and financial viability of
       Harbor Global and discussed its contents with Pioneer's management and
       the third party which prepared such letter; and

                                       29
<PAGE>   34

     - reviewed certain other financial studies and analyses and performed
       certain other investigations as Merrill Lynch deemed necessary, including
       Merrill Lynch's assessment of general economic, market and monetary
       conditions.

     In preparing its opinion, Merrill Lynch relied upon the accuracy and
completeness of all information supplied or otherwise made available to it by
Pioneer, discussed with or reviewed by or for it, or publicly available, and
Merrill Lynch did not assume any responsibility for independently verifying any
of such information. Merrill Lynch did not undertake an independent appraisal of
the assets or liabilities (contingent or otherwise) of Pioneer and did not make
or obtain or assume any responsibility for making or obtaining any independent
appraisals of any of such assets or liabilities. In addition, Merrill Lynch did
not assume any obligation to conduct, nor did it conduct, any physical
inspection of the properties or facilities of Pioneer. With respect to the
financial forecast information provided by Pioneer, Merrill Lynch assumed that
the estimates had been reasonably prepared and reflected the best currently
available estimates and judgments of the management of Pioneer as to the future
financial performance of Pioneer. Merrill Lynch expressed no view with respect
to the estimates of Pioneer's management or the assumptions on which they were
based. In giving their opinion to the board of directors on May 14, 2000,
Merrill Lynch assumed that the merger agreement, when executed and delivered,
would not contain any terms or conditions that differed materially from the
drafts Merrill Lynch reviewed. Merrill Lynch assumed that the merger will be
consummated in accordance with the terms of the merger agreement, without waiver
of any of the conditions to the merger contained in the merger agreement. In
addition, Merrill Lynch relied upon the conclusion set forth in the solvency
letter referred to above.

     Merrill Lynch's opinion was necessarily based on information available to
it and on general market, economic and other conditions as they existed and
could be evaluated on the date of its opinion. Merrill Lynch did not address the
merits of the underlying decision by Pioneer to engage in the merger and the
distribution of shares of Harbor Global. Merrill Lynch expressed no view with
respect to the value of the Harbor Global common shares to be distributed to
Pioneer stockholders or as to how the Harbor Global common shares could be
expected to trade following their issuance.

     Merrill Lynch made a presentation to Pioneer's special committee and board
of directors on May 14, 2000 with respect to certain financial and comparative
analyses performed by Merrill Lynch in evaluating the fairness of the merger
consideration which also provided in substantial part the basis for Merrill
Lynch's opinion dated the date of this proxy statement. The following is a
summary of the material financial analyses furnished by Merrill Lynch to
Pioneer's special committee and board of directors. However, it does not purport
to be a complete description of the analyses performed by Merrill Lynch or of
its presentations to Pioneer's special committee and board of directors. The
following summary includes information presented in tabular format. In order to
understand fully the financial analyses used by Merrill Lynch, these tables must
be read together with the text of each summary. The tables alone do not
constitute a complete description of the financial analyses. The following
quantitative information, to the extent it is based on market data, is, except
as otherwise indicated, based on market data as it existed at or prior to May
14, 2000 and is not necessarily indicative of current or future market
conditions.

     The preparation of a fairness opinion is a complex analytic process
involving various determinations as to the most appropriate and relevant methods
of financial analysis and the application of those methods to the particular
circumstances and, therefore, such an opinion is not readily susceptible to
partial or summary description. No company, business or transaction used in
those analyses as a comparison is identical to Pioneer, the merger or the
distribution of shares of Harbor Global, nor is an evaluation of the results of
those analyses entirely mathematical; rather, it involves complex considerations
and judgments concerning financial and operating characteristics and other
factors that could affect the transactions, public trading or other values of
the companies, business segments or transactions being analyzed. The estimates
contained in those analyses and the ranges of valuations resulting from any
particular analysis are not necessarily indicative of actual or predictive of
future results or values, which may be significantly more or less favorable than
those suggested by those analyses. In addition, analyses relating to the value
of businesses or securities are not appraisals and may not reflect the prices at
which businesses, companies or

                                       30
<PAGE>   35

securities actually may be sold. Accordingly, these analyses and estimates are
inherently subject to substantial uncertainty.

     In arriving at its opinion, Merrill Lynch made qualitative judgments as to
the significance and relevance of each analysis and factor considered by it.
Accordingly, Merrill Lynch believes that its analyses must be considered as a
whole and that selecting portions of its analyses and factors, without
considering all analyses and factors, could create an incomplete view of the
processes underlying such analyses and its opinion. In its analyses, Merrill
Lynch made numerous assumptions with respect to Pioneer, industry performance
and regulatory environment, general business, economic, market and financial
conditions, as well as other matters, many of which are beyond the control of
Pioneer and involve the application of complex methodologies and educated
judgment.

     As the distribution of shares of Harbor Global is designed to vest
separately in the holders of Pioneer common stock full ownership of the
businesses comprising Harbor Global, Merrill Lynch did not perform any
independent valuation analyses with respect to those businesses. Rather, Merrill
Lynch's analyses focused exclusively on the merger consideration, and were
generally grouped into four categories: an analysis of the solicitation by
Merrill Lynch and Salomon Smith Barney of proposals for the acquisition of
Pioneer or its global investment management business; analyses comparing the
merger consideration with the trading prices of companies comparable to the
global investment management business; analyses comparing the merger
consideration with the consideration paid in certain comparable merger and
acquisition transactions; and analyses comparing the merger consideration with
the present value of the projected free cash flows and terminal value of global
investment management business.

     Review of Solicitation Process.  Merrill Lynch included in its presentation
to the Pioneer board a summary of the results of the efforts of Merrill Lynch
and Salomon Smith Barney to solicit proposals for the acquisition of Pioneer and
its global investment management business. Merrill Lynch noted that a total of
82 parties had been contacted, of which:

     - 52 signed confidentiality agreements and were provided with copies of an
       information memorandum regarding Pioneer;

     - 16 submitted preliminary indications of interest (of which 13 conformed
       to the requirements outlined by Merrill Lynch and Salomon Smith Barney);

     - eight performed a detailed on-site due diligence review of Pioneer; and

     - four submitted definitive offers to purchase Pioneer.

     Of the four definitive offers received, UniCredito's proposal offered the
highest purchase price for Pioneer and included other favorable terms.

     Summary of Valuation Analyses.  Merrill Lynch prepared a separate valuation
of Pioneer's global investment management business using several methodologies,
including a comparable company trading analysis, a comparable transactions
analysis and a discounted cash flow analysis. Each of these methodologies was
used to generate ranges of average reference enterprise value for the global
investment management business, which were then compared to the merger
consideration of $43.50 per share. The following table shows the ranges of
average reference enterprise values per share of Pioneer common stock derived
for the global investment management business under each of these methodologies.
This table

     Comparable Company Analysis.  Merrill Lynch reviewed certain publicly
available financial, operating and stock market information for Pioneer and
eight other publicly-traded asset management companies (Franklin Resources,
Inc., BlackRock Inc., Eaton Vance Corporation, Federated Investors, Inc.,
Gabelli Asset Management, Inc., Neuberger Berman, Inc., T. Rowe Price
Associates, Inc., and Waddell & Reed Financial, Inc.) (the comparable
companies). Merrill Lynch considered these companies to be reasonably similar to
Pioneer insofar as they participate in business segments similar to the global
investment management business, but noted that none of these companies has the
same management, makeup, size and combination of businesses as the global
investment management business.

     For each of the comparable companies and for the global investment
management business, Merrill Lynch calculated and compared, among other things,
the ratio of the closing stock price on May 12, 2000 (or, in the case of the
global investment management business, the merger consideration) to: (1) 1999
earnings per share, (2) estimated 2000 earnings per share (using management's
estimates in the case of Pioneer and First Call consensus estimates for the
other companies), (3) 1999 per share earnings before

                                       32

interest, taxes, depreciation and amortization (EBITDA), (4) 1999 revenues per
share and (5) assets under management as of April 30, 2000. The following table
sets forth the results of these calculations.

</TABLE>

     As shown in the table, the ratios implied by the merger consideration
compared favorably to those obtained with respect to the comparable companies.
Based on the ratios obtained with respect to the comparable companies, Merrill
Lynch derived a range of reference enterprise values for the global investment
management business of $15.98 to $26.89 per share of Pioneer common stock.

     For reference purposes, Merrill Lynch also compared the historical
performance of Pioneer common stock with the performance of selected groups of
the comparable companies and the Standard & Poor's index of 500 industrial
stocks (S&P 500). The following table shows the comparison for the one year
period, the two year period (annualized), the three year period (annualized) and
the five year period (annualized) preceding February 4, 2000. The groups of
comparable companies were selected based on the public availability of
historical performance data with respect to their common stocks over the
relevant period of time.

     As shown in the table, Pioneer significantly underperformed both the
comparable companies and the S&P 500 during each of the periods examined.
Merrill Lynch similarly observed that Pioneer compared poorly relative to the
comparable companies with respect to other financial parameters, such as stock
trading multiples, operating margin, EBITDA margin and earnings growth. In
Merrill Lynch's view, these observations enhance its conclusion that the merger
consideration compares favorably to the stock trading prices of the comparable
companies.

     Analysis of Selected Merger and Acquisition Transactions.  Merrill Lynch
analyzed certain publicly available financial, operating and stock market
information for 17 selected merger and acquisition transactions in the asset
management business with a value in excess of $150 million since 1996. The
precedent transactions reviewed were: Allianz A.G./PIMCO Advisors L.P.;
ReliaStar Financial Corporation/Pilgrim Capital Corp; PIMCO Advisors
L.P./Oppenheimer Capital (2/97); Affiliated Managers Group, Inc./Tweedy; Fleet
Financial Corporation/Columbia Management Company; J.P. Morgan/ American
Century; Zurich/Scudder Stevens & Clark; Commerzbank A.G./Montgomery Asset

ment; PIMCO Advisors LP/Oppenheimer Capital (11/97); INVESCO PLC/AIM Management
Group; First Union/Keystone; Franklin Resources, Inc./Heine Securities; Morgan
Stanley and Co. Inc./Van Kampen American Capital; Mellon Bank/Founders; Phoenix
Investment Partners/Engemann; Phoenix Investment Partners/Zweig; and American
International Group/John McStay. In each case, the first-named company
represents the acquiring company in the transactions (comparable to UniCredito
in the merger) and the second-named company represents the acquired company in
the transactions (comparable to Pioneer in the merger). Merrill Lynch considered
the precedent transactions to be reasonably similar to the merger, but none of
these transactions is identical to the merger.

     For each of the precedent transactions, Merrill Lynch derived, among other
things, (1) the ratio of the estimated transaction value to: (a) assets under
management; (b) revenues for the latest twelve months prior to the announcement
of the transaction, and (c) EBITDA for the latest twelve months prior to the
announcement of the transaction, and (2) the ratio of the estimated equity value
of the acquired company (determined as of the last trading day preceding
announcement of the transaction) to latest twelve months' net income. The
following table sets forth the results of these calculations.

     From its analysis of the precedent transactions, Merrill Lynch derived an
implied value per share of Pioneer common stock ranging from $18.89 to $39.55.

     Discounted Cash Flow Analysis.  Merrill Lynch also performed a discounted
cash flow analysis pursuant to which the value of Pioneer common stock was
estimated by adding (1) the estimated present value of the future stream of the
free cash flows of the global investment management business for the years 2000
through 2010, plus (2) the estimated present value of the terminal value per
share of the global investment management business at the end of the year 2010.
For purposes of such analysis, Merrill Lynch utilized discount rates ranging
from 12% to 15%, and perpetual growth rates ranging from 2% to 4%. From this
analysis, Merrill Lynch derived a reference range of implied value for the
global investment management business per share of Pioneer common stock of
$23.94 to $37.34.

     Other Factors.  Merrill Lynch is an internationally recognized investment
banking firm and, as a part of its investment banking business, is regularly
engaged in the valuation of businesses and securities in connection with mergers
and acquisitions. The Pioneer board selected Merrill Lynch as its financial
advisor because of Merrill Lynch's experience, expertise and familiarity with
Pioneer and its businesses.

     Pioneer has agreed to pay Merrill Lynch a fee of approximately $4,750,000
for its financial advisory services in connection with the transaction, payable
as follows:

     - $250,000 upon the execution of the engagement letter between Merrill
       Lynch and Pioneer;

     - $450,000 upon the signing of a definitive agreement; and

     - $4,050,000 payable upon the closing of the transaction.

     Pioneer also has agreed to reimburse Merrill Lynch for its reasonable
out-of-pocket expenses, including the reasonable fees and disbursements of legal
counsel, and to indemnify Merrill Lynch against liabilities arising out of
business combination contemplated by the engagement letter or to contribute to

                                       34
<PAGE>   39

payments Merrill Lynch may be required to make in respect of the liabilities for
which indemnification is contemplated but for which indemnification is
unenforceable.

     In the ordinary course of its business, Merrill Lynch and its affiliates
may actively trade the equity securities of Pioneer, the Pioneer Family of Funds
and the debt and equity securities of UniCredito for their own accounts and for
the accounts of customers. Accordingly, Merrill Lynch and its affiliates may at
any time hold a long or short position in those securities. Merrill Lynch may
provide investment banking services to Pioneer and UniCredito in the future, and
may receive fees for rendering these services.

     Opinion of Salomon Smith Barney Inc.

     Salomon Smith Barney was also retained to act as financial advisor to
Pioneer in connection with the exploration of strategic alternatives for
Pioneer. Pursuant to Salomon Smith Barney's engagement letter, Salomon Smith
Barney rendered oral advice to the Pioneer board of directors on May 14, 2000 to
the effect that, as of such date, the merger consideration was fair, from a
financial point of view, to the Pioneer stockholders.

     Salomon Smith Barney subsequently rendered a written opinion dated the date
of this proxy statement to the effect that, based upon and subject to the
considerations set forth in such opinion, the aggregate consideration to be
received by the Pioneer stockholders in the merger and the distribution of
Harbor Global common shares is fair, from a financial point of view, to such
holders. The full text of Salomon Smith Barney's opinion, which sets forth the
assumptions made, general procedures followed, matters considered and limits on
the review undertaken, is included as Annex D to this proxy statement. The
summary of Salomon Smith Barney's opinion set forth below is qualified in its
entirety by reference to the full text of such opinion. STOCKHOLDERS ARE URGED
TO READ THE SALOMON SMITH BARNEY OPINION CAREFULLY AND IN ITS ENTIRETY.

     In connection with rendering its opinion, Salomon Smith Barney reviewed,
among other things, the following:

     - the merger agreement and held discussions with certain senior officers,
       directors and other representatives and advisors of Pioneer concerning
       its business, operations and financial prospects;

     - certain publicly available business and financial information relating to
       Pioneer as well as certain financial forecasts and other information and
       data for Pioneer, which were provided to or otherwise discussed with
       Salomon Smith Barney by Pioneer's management;

     - the financial terms of the merger as set forth in the merger agreement in
       relation to, among other things, current and historical market prices and
       trading volumes of Pioneer common stock, the historical and projected
       earnings and other operating data of the global investment management
       business and the historical and projected capitalization and financial
       condition of Pioneer and the global investment management business;

     - the results of the efforts of Salomon Smith Barney and Merrill Lynch to
       solicit proposals to acquire Pioneer and the global investment management
       business;

     - certain publicly available information with respect to certain other
       companies that Salomon Smith Barney believed to be comparable to the
       global investment management business and the trading markets for certain
       of such other companies' securities;

     - certain publicly available information prepared by third parties,
       including equity research analysts, concerning the business, operations
       and financial prospects of Pioneer and the sectors in which they operate;

     - the terms of the distribution of Harbor Global common shares and the
       drafts of the related distribution agreement and tax separation
       agreement;

                                       35
<PAGE>   40

     - a letter regarding the solvency and financial viability of Harbor Global
       and discussed their contents with Pioneer's management and the third
       party that prepared such letter;

     - certain publicly available information concerning the trading of, and the
       trading market for, Pioneer common stock; and

     - certain publicly available information concerning the nature and terms of
       certain other transactions that Salomon Smith Barney considered relevant
       to its inquiry.

Salomon Smith Barney also considered such other information, financial studies,
analyses, investigations and financial, economic and market criteria that it
deemed relevant. Salomon Smith Barney also discussed the past and current
business operations and financial conditions of Pioneer as well as other matters
Salomon Smith Barney believed relevant to its inquiry.

     In its review and analysis and in arriving at its opinion, Salomon Smith
Barney assumed and relied upon the accuracy and completeness of all of the
financial and other information provided to it or publicly available and neither
attempted independently to verify nor assumed any responsibility for verifying
any of such information and further relied on assurances of management of
Pioneer that it was not aware of facts that would make any of such information
inaccurate or misleading. Salomon Smith Barney did not conduct a physical
inspection of any of the properties or facilities of Pioneer or UniCredito, and
did not make or obtain or assume any responsibility for making or obtaining any
independent evaluations or appraisals of any of such properties or facilities.
With respect to financial forecasts and other information and data provided to
or otherwise reviewed by or discussed with Salomon Smith Barney regarding
Pioneer, Salomon Smith Barney relied on estimates from the management of
Pioneer, and, at the advice of the management of Pioneer, assumed that the
estimates had been reasonably prepared and reflected the best currently
available estimates and judgments of the management of Pioneer as to the future
financial performance of the global investment management business. Salomon
Smith Barney expressed no view with respect to the estimates of Pioneer
management or the assumptions on which they were based. Salomon Smith Barney
assumed that the merger and the distribution of Harbor Global common shares will
be consummated in a timely fashion in accordance with the terms of the merger
agreement, without waiver of any of the conditions contained in the merger
agreement. In addition, Salomon Smith Barney relied upon the conclusions set
forth in the solvency letter referred to above.

     In conducting its analysis and arriving at its opinion, Salomon Smith
Barney considered such financial and other factors as it deemed appropriate
under the circumstances including, among others, the following:

     - the historical and current financial position and results of operations
       of Pioneer;

     - the historical and current market for Pioneer common stock and the equity
       securities of certain other companies that Salomon Smith Barney believed
       to be comparable to the global investment management business; and

     - the nature and terms of certain other merger and acquisition transactions
       that Salomon Smith Barney believed to be relevant.

     Salomon Smith Barney also took into account its assessment of general
economic, market and financial conditions existing and disclosed to Salomon
Smith Barney as well as its experience in connection with similar transactions
and securities valuation generally. Salomon Smith Barney was not asked to
consider, and its opinion does not address, the relative merits of the
transaction as compared to any alternative business strategy that might exist
for Pioneer. Salomon Smith Barney's opinion necessarily was based on conditions
as they existed and could be evaluated on the date thereof, and Salomon Smith
Barney assumed no responsibility to update or revise its opinion based upon
circumstances or events occurring after such date. SALOMON SMITH BARNEY'S
OPINION DOES NOT CONSTITUTE AN OPINION OR IMPLY ANY CONCLUSION AS TO THE PRICE
AT WHICH PIONEER COMMON STOCK WOULD TRADE FOLLOWING ANNOUNCEMENT OF THE MERGER
OR THE PRICE AT WHICH HARBOR GLOBAL COMMON SHARES WILL TRADE FOLLOWING ITS
DISTRIBUTION. SALOMON SMITH BARNEY'S OPINION WAS PROVIDED FOR THE INFORMATION OF
THE BOARD OF DIRECTORS IN ITS EVALUATION OF THE
                                       36
<PAGE>   41

MERGER AND THE DISTRIBUTION OF THE HARBOR GLOBAL COMMON SHARES AND, IN ANY
EVENT, LIMITED TO THE FAIRNESS, FROM A FINANCIAL POINT OF VIEW, OF THE AGGREGATE
CONSIDERATION TO BE RECEIVED BY THE PIONEER STOCKHOLDERS IN THE TRANSACTION.
SALOMON SMITH BARNEY'S OPINION DID NOT ADDRESS PIONEER'S UNDERLYING BUSINESS
DECISION TO EFFECT THE TRANSACTION NOR DID IT CONSTITUTE A RECOMMENDATION OF THE
TRANSACTION TO PIONEER OR A RECOMMENDATION TO ANY PIONEER STOCKHOLDER AS TO HOW
SUCH STOCKHOLDER SHOULD VOTE WITH RESPECT TO THE TRANSACTION.

     In connection with rendering its advice to Pioneer's special committee and
Pioneer board of directors on May 14, 2000, Salomon Smith Barney made a
presentation with respect to certain analyses performed by it in evaluating the
fairness of the merger consideration. The following is a summary of this
presentation. The summary of certain of the financial analyses includes
information presented in tabular format. IN ORDER TO UNDERSTAND FULLY THE
FINANCIAL ANALYSES USED BY SALOMON SMITH BARNEY, THESE TABLES MUST BE READ
TOGETHER WITH THE TEXT OF EACH SUMMARY. THE TABLES ALONE DO NOT CONSTITUTE A
COMPLETE DESCRIPTION OF THE FINANCIAL ANALYSES. The following quantitative
information, to the extent it is based on market data, is, except as otherwise
indicated, based on market data as it existed at or prior to May 14, 2000 and is
not necessarily indicative of current or future market conditions. Because the
distribution of Harbor Global shares is intended to vest full ownership of the
businesses and assets comprising Harbor Global in the Pioneer stockholders,
Salomon Smith Barney did not perform any independent valuation analyses with
respect to those businesses in connection with its opinion dated the date of
this proxy statement.

     Overview of UniCredito.  Salomon Smith Barney provided a financial overview
of UniCredito, noting that it is one of Italy's largest banks when measured in
terms of market capitalization and that its group of asset management
subsidiaries, EuroPlus, has approximately $80 billion in assets under
management.

     Valuation Analyses

     The following is a summary of the material valuation analyses performed by
Salomon Smith Barney in connection with the advice it rendered on May 14, 2000.

     Summary.  Salomon Smith Barney prepared a separate valuation of the global
investment management business using several methodologies, including normalized
price analysis, public market comparable company trading analysis, precedent
transaction analysis and discounted cash flow analysis. Each of these
methodologies was used to generate a reference range for the value of the global
investment management business, which was then compared to the $31.00 per share
trading price of Pioneer common stock as of May 12, 2000 and the $43.50 per
share merger consideration as part of Salomon Smith Barney's evaluation of the
fairness of the merger consideration. The following table shows the reference
ranges of values per share of Pioneer common stock derived for each of these
methodologies. THIS TABLE SHOULD BE READ TOGETHER WITH THE MORE DETAILED SUMMARY
OF EACH OF THESE VALUATION ANALYSES SET FORTH BELOW.

     Normalized Price Analysis.  As an initial step in its analyses, Salomon
Smith Barney determined a normalized share price for Pioneer common stock as of
May 12, 2000 by multiplying the market price for the Pioneer common stock as of
February 2, 2000, one day prior to the announcement by Southeastern Asset
Management, Inc. that it was exploring possible strategic transactions for
Pioneer by the ratio of the aggregate market capitalization of the companies
comprising the peer group as of May 12, 2000 to the aggregate market
capitalization of such companies as of February 2, 2000. This "normalized" share
price is designed to represent an approximation of the market price for the
Pioneer common stock as of May 12, 2000 absent public statements regarding a
potential transaction and was used by Salomon Smith Barney as a reference point
for its other valuation analyses. Salomon Smith Barney determined that the
aggregate market capitalization of the peer group increased by 0.6% during the
measurement period. Applying this
                                       39
<PAGE>   44

percentage increase to the market price per Pioneer common stock as of February
3, 2000, Salomon Smith Barney obtained a "normalized" price for the Pioneer
common stock of $14.39 per share as of May 12, 2000.

     In considering the results of its various financial analyses set forth
below, Salomon Smith Barney compared the implied valuation ranges resulting from
such analyses to the actual trading price for Pioneer common stock as of
February 2, 2000 of $14.31 per share, the actual trading price for Pioneer
common stock as of May 12, 2000 of $31.00 per share and the "normalized" price
for Pioneer common stock as of May 12, 2000 of $14.39 per share.

     Public Market Comparable Company Analysis.  Using publicly available
information, Salomon Smith Barney analyzed, among other things, the operating
performance and market valuation of two groups of publicly-traded asset
management corporations considered by Salomon Smith Barney to be comparable to
Pioneer and its global investment management business. The first group utilized
by Salomon Smith Barney was the peer group. The second group consisted of
publicly-traded asset management corporations that was a subset of the peer
group whose business or growth characteristics (such as AUM) more closely
resembled those of the global investment management business (the "selected peer
group"). The selected peer group consisted of AMVESCAP PLC, Eaton Vance
Corporation, Federated Investors, Inc., Franklin Resources, Inc., Gabelli Asset
Management Inc. and T. Rowe Price Associates, Inc.

     In order to analyze market valuation, Salomon Smith Barney calculated a
variety of trading multiples, including (1) firm value as a percentage of AUM
and (2) firm value as a multiple of the last twelve months' ("LTM") (a) revenues
and (b) EBITDA, (3) market capital as a multiple of LTM earnings before taxes
and (4) the ratio of the closing stock price on May 12, 2000 as a multiple of
estimated (a) 2000 earnings per share and (b) 2001 earnings per share (as
provided by I/B/E/S).

     The results of these analyses are summarized as follows:

     Using the comparable operating data for the global investment management
business and the average multiple for the measures of value described above,
Salomon Smith Barney calculated reference values for the global investment
management business. Salomon Smith Barney then applied a 30% takeover premium to
such reference values to derive the respective valuation ranges.

     Based upon such analysis, Salomon Smith Barney determined an implied
valuation range of $22.25 to $27.42 per share of Pioneer common stock based on
the peer group and $26.07 to $32.09 per share of Pioneer common stock based on
the selected peer group.

     Precedent Transaction Analysis.  Salomon Smith Barney reviewed publicly
available information with respect to seven precedent transactions occurring
from 1996 to 1999 involving the acquisition of asset management corporations
that were considered by Salomon Smith Barney to be comparable to the global
investment management business with respect to size and/or business mix. These
transactions involved transaction values ranging from $250 million to $1.6
billion. The transactions were as follows:

     - the acquisition of Pilgrim Capital Corporation, valued at $258 million,
       by ReliaStar Financial Corporation in July 1999;

     - the acquisition of Warburg Pincus Asset Management, valued at $602
       million, by Credit Suisse Group in February 1999;

     - the acquisition of Oppenheimer Capital, valued at $793 million, by PIMCO
       Advisors L.P. in November 1997;

     - the acquisition of Columbia Management Company, valued at $550 million,
       by Fleet Financial in August 1997;

     - the acquisition of Montgomery Asset Management, valued at $250 million,
       by Commerzbank AG in March 1997;

     - the acquisition of AIM Management Group, valued at $1.6 billion, by
       INVESCO PLC in November 1996; and

                                       41
<PAGE>   46

     - the acquisition of Van Kampen American Capital, valued at $1.175 billion,
       by Morgan Stanley in June 1996.

     For each precedent transaction, Salomon Smith Barney calculated a variety
of transaction multiples, including (1) purchase price as a percentage of AUM
and (2) purchase price as a multiple of (a) LTM revenues, (b) LTM EBITDA, (c)
LTM earnings before taxes and (d) LTM net income.

     The results of these analyses are summarized as follows:

     Using comparable data for the global investment management business,
Salomon Smith Barney calculated the implied valuation range for the global
investment management business based upon the average multiple for each of the
measures of value described above of $21.93 to $26.91 per share of Pioneer
common stock.

     Discounted Cash Flow Analysis.  Salomon Smith Barney performed a discounted
cash flow ("DCF") analysis with respect to the global investment management
business to determine an implied valuation range for the global investment
management business by discounting (1) projected free cash flows for the five
years ending in 2004 and (2) a terminal value of the global investment
management business based on projected 2004 free cash flows.

     Salomon Smith Barney first reviewed a "base case" scenario, which assumed a
discount rate of 14% and a 9.0x terminal value multiple. In addition, Salomon
Smith Barney reviewed the sensitivity of this analysis by calculating the value
of the global investment management business assuming a range of discount rates
from 13% to 14% and a range of terminal value multiples from 8.0x to 10.0x.
Based upon such analysis, Salomon Smith Barney obtained the following implied
value for the global investment management business per share of Pioneer common
stock:

     The foregoing is a summary of the material financial analyses furnished by
Salomon Smith Barney to the Pioneer board of directors but it does not purport
to be a complete description of the analyses performed by Salomon Smith Barney
or of its presentations to the Pioneer board of directors. The preparation of
financial analyses and fairness opinions is a complex process involving
subjective judgments and is not necessarily susceptible to partial analysis or
summary description. Salomon Smith Barney made no attempt to assign specific
weights to particular analyses or factors considered, but rather made
qualitative judgments as to the significance and relevance of the analyses and
factors considered. Accordingly, Salomon Smith Barney believes that its analyses
(and the summary set forth above) must be considered as a whole, and that
selecting portions of such analyses and of the factors considered by Salomon
Smith Barney, without considering all of such analyses and factors, could create
a misleading or incomplete view of the processes underlying the analyses
conducted by Salomon Smith Barney and its opinion. With regard to the comparable
public company analysis summarized above, Salomon Smith

                                       42
<PAGE>   47

Barney selected comparable public companies on the basis of various factors,
including the size of the public company and similarity of the line of business;
however, no public company utilized as a comparison in such analysis, and no
transaction utilized as a comparison in the comparable transaction analyses
summarized above, is identical to Pioneer, any business segment of Pioneer or
the merger. As a result, these analyses are not purely mathematical, but also
take into account differences in financial and operating characteristics of the
comparable companies and other factors that could affect the transaction or
public trading value of the comparable companies and transactions to which
Pioneer, the business segments of Pioneer and the merger are being compared. In
its analyses, Salomon Smith Barney made numerous assumptions with respect to
Pioneer, UniCredito, industry performance, general business, economic, market
and financial conditions and other matters, many of which are beyond the control
of Pioneer and UniCredito. Any estimates contained in Salomon Smith Barney's
analyses are not necessarily indicative of actual values or predictive of future
results or values, which may be significantly more or less favorable than those
suggested by such analyses. Estimates of values of companies do not purport to
be appraisals or necessarily to reflect the prices at which companies may
actually be sold. Because such estimates are inherently subject to uncertainty,
none of Pioneer, UniCredito, the Pioneer board of directors, Salomon Smith
Barney or any other person assumes responsibility if future results or actual
values differ materially from the estimates.

     Salomon Smith Barney's analyses were prepared solely as part of Salomon
Smith Barney's analysis of the fairness of the merger consideration and were
provided to the Pioneer board of directors in that connection. The opinion of
Salomon Smith Barney was one of the factors taken into consideration by the
special committee and the Pioneer board of directors in making its determination
to approve the merger agreement and the merger.

     Salomon Smith Barney is an internationally recognized investment banking
firm engaged, among other things, in the valuation of businesses and their
securities in connection with mergers and acquisitions, restructurings,
leveraged buyouts, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes. Pioneer selected Salomon
Smith Barney to act as its financial advisor on the basis of Salomon Smith
Barney's international reputation and Salomon Smith Barney's familiarity with
Pioneer. Salomon Smith Barney and its predecessors and affiliates had previously
rendered and is rendering investment banking and financial advisory services to
Pioneer unrelated to the merger, for which they received and will receive
customary compensation. Salomon Smith Barney has also acted as financial advisor
to Pioneer in connection with the disposition of Pioneer's Ghana gold mining
operations. In addition, in the ordinary course of its business, Salomon Smith
Barney and its affiliates (including Citigroup and its affiliates) may actively
trade the debt and equity securities of both Pioneer and UniCredito for its own
account and for the accounts of customers and, accordingly, may at any time hold
a long or short position in such securities. Salomon Smith Barney and its
affiliates (including Citigroup and its affiliates) may maintain relationships
with Pioneer (and Citigroup and its affiliates).

     Pursuant to Salomon Smith Barney's engagement letter, Pioneer (1) has paid
a fee to Salomon Smith Barney of $250,000, upon execution of the engagement
letter, and (2) will pay approximately $4,750,000, 10% of which was paid
promptly upon the signing of definitive documentation related to the merger, and
the remainder of which, less the $250,000 paid in clause (1) and not previously
credited, will be payable upon consummation of the merger. Pioneer has also
agreed to reimburse Salomon Smith Barney for its reasonable travel and other
out-of-pocket expenses incurred in connection with its engagement, including the
reasonable fees and disbursements of its counsel, provided that the aggregate
amount of legal expenses to be reimbursed hereunder (other than expenses to be
reimbursed pursuant to a separate indemnity agreement) will not exceed $75,000
without the consent of Pioneer, such consent not to be unreasonably withheld.
Pursuant to a separate indemnity agreement, Pioneer has agreed to indemnify
Salomon Smith Barney against certain liabilities and expenses relating to or
arising out of its engagement, including certain liabilities under the federal
securities laws.

     As noted under the caption "The Merger -- Reasons for the Merger," the
opinion of Salomon Smith Barney was only one of several factors considered by
the Pioneer board of directors in determining to adopt and approve the merger
agreement and the merger.

PROJECTED FINANCIAL DATA

     Pioneer does not, as a matter of course, make public forecasts or
projections as to future revenues, earnings or other income statement data, cash
flows or balance sheet and financial position information. However, in
connection with the merger, UniCredito and our financial advisors had access to
our projections for the stand alone global investment management businesses for
fiscal years 2000 through 2004.

     We have included a summary of these projections below. These projections do
not reflect any of the effects of the merger, including transaction costs, or
other changes that may in the future be appropriate concerning Pioneer and its
assets, businesses, operations, properties, policies, corporate structure,
capitalization and management in light of the circumstances then existing. These
projections also do not include the businesses and assets being transferred to
Harbor Global. Pioneer believes that the assumptions were reasonable at the time
they were prepared, given the information known by our management.

     Pioneer did not prepare the projections for fiscal years 2000 through 2004
with a view toward public disclosure or compliance with published guidelines of
the Securities and Exchange Commission or the American Institute of Certified
Public Accountants regarding forward-looking information or generally accepted
accounting principles. Neither our independent auditors, nor any other
independent accountants, have compiled, examined or performed any procedures
with respect to the prospective financial information contained in these
projections nor have they expressed any opinion or given any form of assurance
on this information or its achievability. We assume no responsibility for, and
disclaim any association with, this prospective financial information.

     In preparing our projections for fiscal years 2000 through 2004, we
necessarily made numerous assumptions, many of which are beyond our control and
may prove not to have been, or may no longer be, accurate. Except as otherwise
indicated, this information does not reflect revised prospects for our business,
expenditures associated with the sale of Pioneer, including the consummation of
the transaction with UniCredito, changes in general business and economic
conditions or any other transaction or event that has occurred or that may occur
and that we did not anticipate at the time we prepared this information.
Accordingly, this information is not necessarily indicative of current values or
future performance, which may be significantly more favorable or less favorable
than as set forth below, and you should not regard our including these
projections in this prospectus as a representation that they will be achieved.

     The projections for fiscal years 2000 through 2004 are not guarantees of
performance. These projections involve risks, uncertainties and assumptions. The
future financial results and our stockholder value may differ materially from
those expressed in these projections. Many of the factors that will determine
these results and values are beyond Pioneer's ability to control or predict. You
should not place undue reliance on these projections. Our future financial
results may vary materially from these projections. We do not intend to update
or revise these projections.

(1) Cumulative average growth rate (CAGR) from 2000 through 2004.

(2) Represents unrealized and realized gains on venture capital, marketable
    securities and long-term investments and also includes an $8.1 million gain

     The projections for the years 2001 through 2004 are based on a number of
assumptions, including, but not limited to, the following:

     - Asset flows, including gross sales, market performance and redemptions
       are projected separately for the six largest U.S. mutual funds and nine
       other assets under management "buckets." The projections reflect trends
       within funds or groups of funds.

     - 3.0% equity market appreciation rate in 2000 and 7.5% thereafter.

     - Management fees were adjusted for assumed performance enhancements and
       specific contractual fee adjustments based on assets under management.

     - Other Revenues:

      Shareholder services fees -- assumed to grow at a rate equal to the growth
      in net assets under management, excluding market performance.

      Underwriting commissions -- calculated as a percentage of gross sales. In
      1998, Pioneer entered into an agreement to sell to a third party its
      rights to receive future distribution fees and deferred sales charges from
      the sale of Class B shares through September 30, 2001. The projections
      assume this program continues after September 30, 2001.

      Trustee fees -- assumed to grow at a rate equal to the growth in net
      assets under management, excluding market performance.

      Other income -- no assumed growth.

     - Expenses:

      Compensation and Benefits -- calculated as a percentage of investment
      management revenues, consistent with Pioneer's budget for 2000.

      Selling Expenses -- assumed to be constant as a percentage of gross sales.

      Other Expenses -- 5% annual growth rate assumed.

      Taxes -- An effective tax rate of approximately 35% has been used.

      Depreciation -- 3% annual growth rate assumed.

      Amortization -- goodwill amortization from the 1993 Mutual of Omaha
      acquisition at $1.5 million annually through 2009; amortization of
      commission on sales of Class C shares of U.S. mutual funds assumed to be
      flat at $2.4 million annually.

TREATMENT OF PIONEER OPTIONS AND RESTRICTED STOCK

     We have issued and outstanding under our 1988 Stock Option Plan, as
amended, and Amended and Restated 1997 Stock Incentive Plan, options to purchase
2,141,406 shares of Pioneer common stock at a weighted-average exercise price of
$16.38 per share. Options to purchase 1,093,006 of these shares were unvested at
June 22, 2000, and options to purchase 1,048,400 shares were vested and
unexercised on that date. We have also issued to current employees 1,583,474
shares of restricted stock under our 1995 Restricted Stock Plan and Amended and
Restated 1997 Stock Incentive Plan at a purchase price of $0.10 per share, of
which 556,982 shares were unvested at June 22, 2000. Immediately prior to the
merger, each unvested share of restricted stock and each unvested stock option
will become fully vested. At the effective time of the merger, each share of
restricted stock will convert to the right to receive a cash payment of $43.50.
Holders of restricted stock also will receive the distribution of Harbor Global
common shares. As soon as practicable after the merger, each holder of an option
to purchase shares of Pioneer common stock will receive a cash payment equal to
the excess of $43.50 over the per share exercise price of such option,

                                       46
<PAGE>   51

multiplied by the number of shares subject to the option. Unless option holders
exercise their options prior to the effective time of the merger, option holders
will not be record holders of Pioneer common stock and, consequently, will not
be entitled to participate in the distribution of shares of Harbor Global.

INTERESTS OF EXECUTIVE OFFICERS AND DIRECTORS OF PIONEER IN THE MERGER

     In considering the recommendation of the Pioneer board of directors with
respect to the merger, you should be aware that the executive officers and
certain directors of Pioneer have interests in the merger that are in addition
to your interests as a stockholder of Pioneer generally. The Pioneer board of
directors and the members of the special committee were aware of these potential
conflicts and considered them in approving the merger. In addition, certain
executive officers and directors of Pioneer are significant stockholders of
Pioneer and will receive substantial consideration for their shares. See
"Security Ownership of Certain Beneficial Holders and Management of Pioneer."

     Stock Ownership and Voting

     Four of the officers of Pioneer, Mr. Cogan, Mr. Tripple, Eric W. Reckard
and Robert P. Nault, have entered into a voting agreement with UniCredito
relating to the proposed merger. As of the record date, these parties
collectively owned or had beneficial control over 4,495,875 shares of the
outstanding shares of Pioneer common stock (including restricted stock but
excluding stock issuable upon the exercise of options), or approximately 16.2%
of the outstanding shares of Pioneer common stock. In the voting agreement,
these parties agreed to vote all of the shares of Pioneer common stock they
beneficially own or over which they exercise voting control in favor of the
merger, against any competing merger proposal and against any action that would
result in a breach of Pioneer's representations and warranties in the merger
agreement.

     Acceleration of Unvested Stock Options and Restricted Stock

     All unvested options and restricted stock granted by Pioneer under any of
its plans or arrangements, including the options and restricted stock held by
the executive officers and directors of Pioneer, will become fully vested on an
accelerated basis immediately prior to the effective time of the merger,
including:

     - options to purchase 203,000 shares of Pioneer common stock held by Mr.
       Cogan, the president, chief executive officer and chairman of the board
       of directors of Pioneer;

     - options to purchase 103,000 shares of Pioneer common stock and 12,653
       shares of restricted stock held by Mr. Tripple, an executive vice
       president and a director of Pioneer;

     - options to purchase 85,000 shares of Pioneer common stock and 4,387
       shares of restricted stock held by Mr. Reckard, the chief financial
       officer and an executive vice president of Pioneer;

     - options to purchase 104,000 shares of Pioneer common stock and 11,077
       shares of restricted stock held by Stephen G. Kasnet, an executive vice
       president of Pioneer;

     - options to purchase 90,000 shares of Pioneer common stock and 8,554
       shares of restricted stock held by Alicja K. Malecka, an executive vice
       president of Pioneer;

     - options to purchase 95,000 shares of Pioneer common stock and 11,594
       shares of restricted stock held by William H. Smith, Jr., an executive
       vice president of Pioneer;

     - options to purchase 15,000 shares of Pioneer common stock and 15,000
       shares of restricted stock held by Adriana Stadecker, senior vice
       president and director of human resources of Pioneer;

     - options to purchase 73,000 shares of Pioneer common stock and 6,552
       shares of restricted stock held by Mr. Nault, senior vice president and
       general counsel of Pioneer;

                                       47
<PAGE>   52

     - options to purchase 100,000 shares of Pioneer common stock held by Alan
       J. Strassman, vice chairman and a director of Pioneer; and

     - options to purchase 25,700 shares of Pioneer common stock and 3,186
       shares of restricted stock held by Dr. Jaskaran S. Teja, a director of
       Pioneer.

     Executive Retention Agreements

     All executive officers (other than Mr. Cogan) as well as Mr. Strassman and
Dr. Teja, who are directors of Pioneer, have entered into executive retention
agreements with Pioneer. Each retention agreement contains provisions to
compensate the executive in the event of a change in control of Pioneer. Upon
the occurrence of a change in control, each outstanding option to purchase
shares of Pioneer common stock becomes immediately exercisable in full and each
outstanding share of restricted stock is deemed to be fully vested and no longer
subject to a right of repurchase by Pioneer. For purposes of the retention
agreements, the merger and transactions contemplated by the merger agreement
constitute a change in control of Pioneer. Additionally, each retention
agreement provides that in the event of a change in control and subsequent
termination of employment other than for cause, or by the executive for good
reason, within 24 months (12 months in the case of Dr. Teja) of the change in
control, the executive will be entitled to receive from Pioneer a single lump
sum payment equal to the total of:

     - three times (or one in the case of Dr. Teja) the sum of the executive's
       annual base salary and the executive's full normal annual bonus
       compensation immediately prior to termination of employment; plus

     - the sum of the executive's base salary through the date of termination of
       employment, plus the executive's prorated annual bonus compensation
       immediately prior to the termination of employment, plus the amount of
       any deferred compensation and vacation time, plus any accrued earnings or
       interest, each to the extent not already paid.

     For purposes of the foregoing, normal annual bonus compensation is assumed
to be 100% of the executive's annual base salary.

     In the event of termination of employment under the circumstances described
in the paragraph above, Mr. Cogan, Mr. Tripple, Mr. Smith, Mr. Kasnet and Ms.
Malecka, will receive cash payments of $0, $2,550,000, $1,800,000, $1,800,000
and $1,800,000, respectively; and the aggregate cash payments under such
circumstances for all executive officers (as well as Mr. Strassman and Dr. Teja)
would be $13,810,002. It is not expected that Mr. Kasnet will be entitled to
such a payment as a result of his acceptance of employment with Harbor Global.

     If a severance payment is subject to an excise tax pursuant to Section
280(G) of the Internal Revenue Code, the severance payment will be reduced to
eliminate the excise tax provided such a reduction would improve the executive's
after-tax proceeds.

     In addition to the cash compensation described above, each covered
executive will be entitled to remain a participant in all employee benefit plans
maintained by Pioneer at the time of the termination of employment for a period
of 24 months (12 months in the case of Dr. Teja) after such termination.
Finally, each retention agreement provides that the executive will receive
conventional outplacement services having a value of not more than 20% of the
executive's annual base salary.

     At his request, Mr. Cogan was not provided a retention agreement. However,
the compensation committee of the board of directors of Pioneer concluded that
his participation in any transaction involving Pioneer would be essential. As a
result, Pioneer has agreed to pay a $700,000 bonus fee to Mr. Cogan upon the
consummation of a significant transaction affecting the company, including the
proposed transactions with UniCredito. Additionally, Mr. Cogan will be entitled
to remain a participant in all employee welfare benefit plans maintained by
Pioneer at the time of his termination of employment

                                       48
<PAGE>   53

following a change in control of Pioneer for a period of 24 months after such
termination. In the event that Mr. Cogan's employment is terminated either
before or after any change in control of Pioneer, Pioneer is not contractually
obligated to make any payment to Mr. Cogan. Mr. Cogan's $700,000 bonus is
triggered only by the closing of a significant transaction affecting Pioneer
and, therefore, is not considered a substitute for the type of severance
payments to which the other executive officers are entitled under the
circumstances described above.

     Employment Arrangements

     While not a condition to the closing of the merger, some of the executive
officers of Pioneer are expected to continue to be officers of Pioneer or other
affiliates of UniCredito. Pioneer anticipates, for example, that Mr. Cogan will
become deputy chairman of UniCredito's global asset management business and
non-executive chairman of UniCredito's United States asset management operations
and Mr. Tripple will become chief executive officer of UniCredito's U.S. asset
management operations. As of the date of this proxy statement, none of the
executive officers has entered into an employment agreement with UniCredito or
any of its affiliates.

     Affiliation with Harbor Global

     Certain directors and officers of Pioneer will be affiliated with Harbor
Global. Mr. Curtin, Mr. Sanders and Mr. Valentine, each of whom is a director of
Pioneer and a member of the special committee, are expected to constitute the
board of directors of Harbor Global. In addition, certain officers of Pioneer
will own and operate Calypso Management LLC, which has agreed to manage the
liquidation of Harbor Global and operate its assets until they are liquidated.
It is expected that Harbor Global will pay the operating expenses of Calypso
Management incurred in connection with the provision of services to Harbor
Global. As compensation for its provision of services to Harbor Global, Calypso
Management is expected to receive a portion of the net proceeds distributed from
the liquidation of the assets of Harbor Global, generally according to the
following schedule:

     - with respect to the first $36 million in net proceeds available for
       distribution, Calypso Management shall receive a payment equal to 10% of
       such net proceeds;

     - with respect to the next $72 million in net proceeds available for
       distribution, Calypso Management shall receive a payment equal to 7.5% of
       such net proceeds; and

     - with respect to any additional net proceeds, Calypso Management shall
       receive a payment equal to 10% of such net proceeds.

Net proceeds will not include any unexpended portion of the $25 million
contributed by Pioneer to Harbor Global. The proceeds received by Pioneer
Goldfields II in connection with the sale of its Ghanaian gold mine to Ashanti
will not be subject to the preceding schedule. Instead, Calypso Management will
receive only 5% of the Ashanti proceeds that are distributed, if any. Harbor
Global will also pay Mr. Kasnet a signing and retention bonus of $1.8 million if
he remains employed by Calypso Management and Calypso Management continues to
provide services to Harbor Global on the second anniversary of the distribution
date, or if Mr. Kasnet is terminated without cause prior to the second
anniversary of the distribution date. See "Certain Relationships and Related
Transactions" in the Harbor Global information statement attached as Annex B to
this proxy statement.

     Indemnification Arrangements

     Under the merger agreement, UniCredito has agreed, for a period of six
years after the effective date of the merger, to continue all rights to
indemnification, advancement of expenses, exculpation, limitation of liability,
and any similar rights, existing at the time of the merger in favor of the
employees, agents, directors or officers of Pioneer. UniCredito has also agreed
to provide each individual who served as a

                                       49
<PAGE>   54

director or officer of Pioneer at any time prior to the merger with liability
insurance for a period of six years after the merger no less favorable in
coverage and amount than was in effect prior to the merger.

REGULATORY APPROVALS

     Foreign Approvals.  Under the laws of some foreign countries, the merger
and the related transactions may not be consummated unless certain approvals are
obtained from these countries' regulatory authorities. In the following
countries, the designated agency must approve certain aspects of Pioneer's
business and/or the merger and the related transactions; provided that only the
approval of the Bank of Italy and the Central Bank of Ireland are conditions to
the closing of the merger.

     - In Italy, the Bank of Italy;

     - In Ireland, the Central Bank of Ireland and the Department of Enterprise,
       Trade and Employment;

     - In Hong Kong, the Futures and Securities Commission; and

     - In the Czech Republic, the Czech Securities and Exchange Commission.

     Additionally, in some countries, Pioneer and UniCredito are required to
notify certain governmental agencies of the transactions contemplated by the
merger agreement. In particular, under the laws of each of the following
countries, the designated agency has been or will be notified of the merger and
the related transactions. However, none of the following regulatory filings is a
condition to the closing of the merger.

     - In Taiwan, Securities and Exchange Commission;

     - In India, the Securities Exchange Board of India; and

     - In Germany, the German Banking Authorities and Bundesaufsichtsamt fur das
       v Kreditwesen.

     In addition, the establishment of Harbor Global and the transfer of certain
Pioneer businesses to Harbor Global involve various foreign regulatory consents,
including approvals of certain Russian authorities. Because the establishment
and distribution of interests in Harbor Global are conditions to the closing of
the merger, such approvals must be obtained prior to closing the merger.

     Banking and Antitrust Approvals.  Under the merger agreement, UniCredito,
as a condition to closing, must either (i) qualify as a "financial holding
company" under the U.S. Bank Holding Company Act of 1956, as amended by the
Gramm-Leach-Bliley Act of 1999 or (ii) obtain the approval of the Board of
Governors of the U.S. Federal Reserve System prior to its acquisition of
Pioneer. UniCredito will file an application with the Federal Reserve Board to
obtain prior approval of the acquisition. There can be no assurances that such
approval will be obtained or that conditions unacceptable to UniCredito will not
be imposed in connection with any such approval. Because UniCredito is required
to obtain the approval of the Federal Reserve Board to complete the transaction,
Pioneer and UniCredito are required only to make a notice filing under the
Hart-Scott-Rodino Antitrust Improvements Act at least 30 days before
consummation of the merger, and no waiting period will be imposed.

     In Europe, UniCredito must obtain the approval of the Bank of Italy, its
primary regulator, in order to complete the merger. Obtaining such approval is a
condition to the closing of the merger. There can be no assurance that the Bank
of Italy will approve the transaction.

     Because both UniCredito and Pioneer have operations in Europe, the merger
may be subject to approval under regulation (EC) No. 4054189, as amended, of the
Council of the European Union. While Pioneer does not believe that the merger
raises any significant anti-trust issues, there can be no assurance as to the
timing or the outcome of such anti-trust approval by the European Union.

                                       50
<PAGE>   55

     The filings and approvals referenced above are still pending. Pioneer
cannot predict whether it or UniCredito will obtain all the required regulatory
approvals within the time frame contemplated by the merger agreement or without
becoming subject to burdensome conditions.

     General.  Except as described in this section, we are not aware of any
other material filing, approval or other action by any federal or state
governmental or administrative authority that Pioneer must obtain in connection
with the merger. Should any other similar approval or action be required,
Pioneer currently contemplates seeking that approval or taking that action, but
such approvals or actions are not conditions to the closing of the merger.

     State Anti-Takeover Statutes.  Section 203 of the Delaware General
Corporation Law prohibits business combination transactions involving a Delaware
corporation, such as Pioneer, and an "interested stockholder" for three years
following the time the person became an interested stockholder. Section 203
defines an interested stockholder in general as any person that directly or
indirectly beneficially owns 15% or more of the outstanding voting stock of the
subject corporation. The prohibitions in Section 203 do not apply if special
requirements are met or exceptions apply, including that prior to the time a
person became an interested stockholder the board of directors of the subject
corporation approved either the business combination or the transaction which
resulted in such person being an interested stockholder. The merger is not
prohibited by Section 203 of the Delaware General Corporation Law.

     A number of other states have adopted laws and regulations applicable to
attempts to acquire securities of corporations which are incorporated, or have
substantial assets, stockholders, principal executive offices or principal
places of business, or whose business operations otherwise have substantial
economic effects, in such states. In 1982, in Edgar v. MITE Corp., the Supreme
Court of the United States invalidated on constitutional grounds the Illinois
Business Takeover Statute, which, as a matter of state securities law, made
takeovers of corporations meeting the statute's requirements more difficult.
However, in 1987, in CTS Corp. v. Dynamics Corp. of America, the Supreme Court
held that the state of Indiana may, as a matter of corporate law, and, in
particular, with respect to those aspects of corporate law concerning corporate
governance, constitutionally disqualify a potential acquiror from voting on the
affairs of a target corporation without the prior approval of the remaining
stockholders. The state law before the Supreme Court was by its terms applicable
only to corporations that had a substantial number of stockholders in that state
and were incorporated there.

     Pioneer, directly or through our subsidiaries, conducts business in a
number of states throughout the United States, some of which have enacted
anti-takeover laws. We do not know whether any of these laws will, by their
terms, apply to the merger, and we have not necessarily complied with any such
laws. Should any person seek to apply any state anti-takeover law to the merger,
Pioneer will take such action as then appears desirable, which may include
challenging the validity or applicability of any such statute in appropriate
court proceedings. In the event it is asserted that one or more state
anti-takeover laws is applicable or valid as applied to the merger, Pioneer may
be required to file information with, or receive approvals from, the relevant
state authorities. In addition, if enjoined, we may be delayed in consummating
the merger.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

     The following is a general summary of certain material United States
federal income tax consequences to the Pioneer stockholders of the merger,
including the receipt of Harbor Global common shares, but does not purport to be
a complete analysis of all potential tax considerations relating thereto. No
foreign, state or local tax considerations are addressed, nor are federal tax
considerations other than income tax considerations. This summary is based on
current provisions of the Internal Revenue Code of 1986, as amended, currently
applicable Treasury regulations, and judicial and administrative decisions and
rulings. Legislative, judicial or administrative changes or interpretations may
be forthcoming that could alter or modify these statements. Any such changes or
interpretations could be retroactive and could affect the tax consequences to
the Pioneer stockholders. This summary applies only to the Pioneer stockholders

                                       51
<PAGE>   56

who hold their shares as capital assets and does not discuss all of the United
States federal income tax consequences that may be relevant to particular
Pioneer stockholders subject to special treatment, such as:

     - banks;

     - tax-exempt organizations;

     - insurance companies;

     - mutual funds;

     - traders in securities who elect to apply a mark-to-market method of
       accounting;

     - dealers in securities or foreign currencies;

     - stockholders who received their Pioneer common stock through the exercise
       of employee stock options or otherwise as compensation;

     - stockholders who are not United States taxpayers;

     - stockholders who hold Pioneer common stock as part of a hedge, straddle
       or conversion transaction;

     - stockholders who hold Pioneer common stock through a partnership, trust,
       or other entity that is treated as a pass through entity for United
       States federal income tax purposes; or

     - stockholders subject to the alternative minimum tax.

     Receipt of Cash for Pioneer Common Stock

     The exchange of the shares of Pioneer common stock for cash will be a
taxable transaction to the holders of such shares for federal income tax
purposes. In general, each stockholder will recognize gain or loss in an amount
equal to the difference between the cash received and such stockholder's
adjusted tax basis in the stockholder's shares. Such gain or loss will be a
capital gain or loss if a stockholder has held his, her or its shares as a
capital asset. Capital gain or loss will be a long-term capital gain or loss if
a stockholder has held his, her or its shares for more than 12 months as of the
closing of the merger. There are certain limitations on the deductibility of
capital losses. Capital gains of individuals derived in respect of capital
assets held for more than 12 months are eligible for reduced rates of taxation.
It is the responsibility of each stockholder to determine the adjusted tax basis
of his, her or its shares.

     Neither Pioneer nor Harbor Global has sought or will seek a ruling from the
Internal Revenue Service or a legal opinion regarding any tax matter discussed
in this proxy statement, including any tax consequences relating to the
formation of Harbor Global or the tax consequences of the merger and the
distribution or the holding of Harbor Global common shares. Neither Pioneer nor
Harbor Global can assure you that the Internal Revenue Service would not assert,
or that a court would not sustain, a position contrary to any of the tax
consequences described below.

     Receipt of Shares of Harbor Global

     The United States federal income tax consequences to you of receiving
Harbor Global common shares in the distribution may differ significantly
depending on whether the distribution and merger are treated as a single
integrated transaction or as two separate transactions for United States federal
income tax purposes. Although there is no specific authority directly on point,
UniCredito, Pioneer and Harbor Global intend to characterize the merger and the
distribution as a single integrated transaction for United States federal income
tax purposes. Notwithstanding this intention, because the issue is not free from
doubt, you should consult your tax advisor with respect to the proper treatment
of the distribution of Harbor Global common shares.

                                       52
<PAGE>   57

     In general, the receipt by you of Harbor Global common shares in connection
with the merger and the distribution will be a taxable event. If the merger and
the distribution are treated as a single, integrated transaction, the receipt by
you of cash and Harbor Global common shares will be treated as an exchange of
shares of Pioneer for both cash and shares of Harbor Global common shares. Under
this treatment, you will generally recognize capital gain or loss for United
States federal income tax purposes equal to the difference between (1) the
amount of cash received plus the fair market value at the time of the
distribution of the Harbor Global common shares you receive and (2) the adjusted
tax basis in Pioneer common stock you surrender in exchange for the cash and
Harbor Global common shares.

     Such gain or loss will be long-term capital gain or loss if your holding
period for Pioneer common stock you exchange is more than 12 months as of the
closing of the merger. If you own more than one block of shares of Pioneer
common stock, the cash and Harbor Global common shares you receive must be
allocated ratably among the blocks in the same proportion that the number of
shares in a particular block bears to the total number of shares owned by you.
Your holding period for the Harbor Global common shares you receive in the
distribution will begin on the day following the date of the distribution, and
you will have an initial tax basis in the Harbor Global common shares equal to
their fair market value.

     If the merger and distribution are not treated as a single integrated
transaction for United States federal income tax purposes, the receipt of cash
in exchange for shares of Pioneer common stock would result in the recognition
of gain or loss as described above, while the receipt of Harbor Global common
shares may instead be taxable to you as a distribution from Pioneer under
section 301 of the Internal Revenue Code.

     If the receipt of the Harbor Global common shares were treated as a
distribution under section 301 of the Internal Revenue Code, the amount of such
distribution for United States federal income tax purposes would be the fair
market value of the Harbor Global common shares at the time of the distribution.
Under section 301 of the Internal Revenue Code, your receipt of the Harbor
Global common shares would be taxable to you as a dividend at ordinary income
tax rates to the extent of Pioneer's current or accumulated earnings and
profits, including earnings and profits arising from the deemed sale by Pioneer
of the Harbor Global common shares as a result of the distribution. The value of
Harbor Global common shares that exceeds the earnings and profits of Pioneer
would first be treated as a non-taxable return of capital to the extent of your
basis in your shares of Pioneer common stock, and your adjusted tax basis in
such stock would be reduced accordingly (but not below zero). To the extent that
the value of Harbor Global common shares you receive were to exceed your
adjusted tax basis in your shares of Pioneer common stock, such excess would be
treated as long-term or short-term capital gain from the sale or exchange of
Pioneer common stock, depending on the period of time you held such stock.

     As discussed above, the amount of income, gain or loss, if any, that you
will recognize will depend, in part, on the fair market value of the Harbor
Global common shares you receive in the distribution. Harbor Global will
undertake to provide you with its determination regarding the fair market value
of the Harbor Global common shares you receive in the distribution. However, any
such determination will not be binding on the Internal Revenue Service, which
may assert a different, and possibly higher, value for the shares of Harbor
Global common shares you receive. Accordingly, there can be no assurance as to
the exact amount of income, gain or loss you may recognize as a result of the
merger and the distribution.

     You may also be subject to information reporting and to backup withholding
at a rate of 31% of amounts paid to you, unless you provide proof of an
applicable exemption or a correct taxpayer identification number, and otherwise
comply with applicable requirements of the backup withholding rules.

     Bermuda and United States Tax Status of Harbor Global

     Harbor Global believes that it will not be subject to taxation in Bermuda
and that interest, dividends and gains distributed by Harbor Global to you will
not be subject to taxation in Bermuda.

                                       53
<PAGE>   58

     For United States federal income tax purposes, Harbor Global will elect to
be classified as a partnership. Harbor Global believes that it will not be
classified as a "publicly traded partnership" or otherwise classified as a
corporation for United States federal income tax purposes. It is anticipated
that for United States federal income tax purposes you will be treated as a
partner in the Bermuda partnership and your Harbor Global common shares will
represent partnership interests.

     United States Federal Income Tax Consequences of Holding Harbor Global
Common Shares

     By reason of its classification as a partnership for United States federal
income tax purposes, Harbor Global will not itself be subject to United States
federal income tax. Instead, items of income, gain, loss, deduction and expense
will pass through to you, and you will be treated as a partner in Harbor Global
for United States federal income tax purposes.

     As a partner in Harbor Global, you will be required to take into account
your allocable share of Harbor Global's items of income, gain, loss, deduction
and credit. The amount of your allocable share of Harbor Global's items of
income, gain, loss, deduction and credit will be determined in accordance with
your interest in Harbor Global. Your adjusted tax basis in the Harbor Global
shares generally will be equal to the fair market value of the Harbor Global
shares you receive at the time of the distribution and will be (1) increased by
your allocable share of Harbor Global's items of income and gain that you are
required to take into account as described above and (2) decreased, but not
below zero, by the allocable share of Harbor Global's items of deduction and
loss and the amount of any cash or other distribution made by Harbor Global to
you. Cash distributions that Harbor Global makes to you generally will not be
taxable to you, except to the extent that such distributions exceed your
adjusted tax basis in your Harbor Global common shares.

     Because Harbor Global will not be required to make current distributions of
its earnings, it is possible that your United States federal income tax
liability directly (as described below under the heading "Investments in Foreign
Corporations"), or with respect to your allocable share of Harbor Global's items
of income, gain, loss, deduction and credit, in a particular taxable year could
exceed the cash distributions, if any, to you for that year. In this case, you
may have a liability for tax which must be paid by you out of other funds.

     Harbor Global's disposition of businesses or assets may generally give rise
to income, gain or loss, which will pass through to you, as described above.
Except as described below under the heading "Passive Foreign Investment
Company," this gain will be treated as long-term capital gain if Harbor Global's
holding period in the stock is more than 12 months at the time of the sale. For
this purpose, Harbor Global's holding period will include any period during
which the stock was held as a capital asset by Pioneer. Harbor Global expects to
distribute proceeds from the sale of its assets, net of its expenses and any
contingent liabilities, pro rata to you.

     Investments in Foreign Corporations

     As a result of the structure of Harbor Global, you may be required to
recognize a proportionate share of the income earned by any majority or minority
owned Harbor Global subsidiary that is classified as a Foreign Personal Holding
Company or a Passive Foreign Investment Company. You are urged to consult your
tax advisor as to whether making a qualified electing fund election, as
described below, with respect to each Passive Foreign Investment Company would
be beneficial to you.

     Foreign Personal Holding Company

     Harbor Global believes that one or more of its foreign subsidiaries may be
classified as a "foreign personal holding company" (an "FPHC"). In general, a
foreign corporation will be classified as an FPHC if in any taxable year if (1)
five or fewer individuals who are United States citizens or residents own or are
deemed to own more than 50% (measured by the total voting power of all classes
entitled to vote or the total value) of the foreign corporation's shares (the
"ownership test") and (2) at least 60% (50% in some cases) of the foreign
corporation's gross income consists of "foreign personal holding company
income,"
                                       54
<PAGE>   59

which generally includes passive income such as dividends, interests, gains from
the sale or exchange of shares or securities, rent and royalties (the "income
test").

     For purposes of determining whether a foreign corporation meets the
ownership test described above, you will be treated as owning your proportionate
share of stock in any foreign corporation held by Harbor Global, and the shares
that are treated as owned by you will be attributed to all other shareholders of
Harbor Global. Therefore, any foreign corporation owned by Harbor Global will
generally be treated as owned, through attribution, by each Harbor Global
shareholder in the same proportion that such company is owned by Harbor Global,
so that the ownership test will be satisfied with respect to any company that is
owned more than 50 percent by Harbor Global. As a result, any foreign
corporation that is more than 50% owned by Harbor Global will be treated as an
FPHC based solely on whether the income test is satisfied. In addition, Harbor
Global believes that one or more of the subsidiaries of Harbor Global will have
substantial passive income, and as a result may be classified as an FPHC under
the income test.

     In the event that any foreign subsidiary of Harbor Global is classified as
an FPHC, you will be required to include in income your proportionate share of
the subsidiary's undistributed foreign personal holding company income,
regardless of whether you receive corresponding distributions of cash.

     Harbor Global will undertake to provide you with information regarding the
classification of any Harbor Global subsidiary as an FPHC and your allocable
share of the subsidiary's income, as described above. However, Harbor Global
cannot assure you that it will be able to provide you with this information.

     Passive Foreign Investment Company

     One or more of Harbor Global's subsidiaries could also be classified as a
passive foreign investment company (a "PFIC"). In general, a foreign corporation
will be a PFIC if, for any taxable year, either (1) 75% or more of its gross
income is "passive income," which includes interest, dividends, and some types
of rents and royalties, or (2) the average percentage of the corporation's
assets that produce or are held for the production of "passive income" is 50% or
more. If any of the foreign corporations owned directly or indirectly by Harbor
Global is a PFIC during any year in which you own Harbor Global common shares,
you will be treated as directly owning your proportionate share of such PFIC.
Unless a qualified electing fund election is made, as described below, you will
be subject to tax on gains on dispositions of PFIC shares by Harbor Global or a
subsidiary of Harbor Global and on certain "excess distributions" by a PFIC to
Harbor Global as if the gain or distribution were ordinary income earned ratably
over each of the years during the period in which the subsidiary was classified
as a PFIC and you are treated as owning an indirect interest in the PFIC. You
generally will be liable to pay tax at the ordinary income rates prevailing
during each of the years to which the gain or distribution is allocable, except
that in the case of gains and distributions allocable to prior years in which
the foreign corporation was a PFIC, (1) the tax rate will be the highest in
effect for that taxable year and (2) the tax will be payable generally without
regard to offsets from deductions, losses and expenses. You will also be subject
to an interest charge with respect to any tax described above that is allocated
to a prior year.

     Alternatively, you may make an election with respect to each PFIC in which
you are treated as owning shares to have the PFIC treated as a "qualified
electing fund" ("QEF"). In general, such an election would require you to
include in gross income each year your share of the PFIC's ordinary income and
net capital gain for the year, even if the PFIC does not distribute cash or
other property in respect of such income. You may only make a QEF election if
the PFIC satisfies certain reporting requirements with respect to its ordinary
income and net capital gains.

     In addition, subject to specific limitations, shareholders treated as
owning marketable shares in a PFIC may make an election to mark those shares to
market annually, rather than being subject to the above-described rules. Amounts
included in or deducted from income under this mark-to-market election and
actual gains and losses realized upon disposition, subject to specific
limitations, would be treated as ordinary gains or losses.

                                       55
<PAGE>   60

     As mentioned above, Harbor Global expects that one or more of its
subsidiaries will have substantial passive income. Accordingly, Harbor Global
expects that one or more of its subsidiaries will be classified as a PFIC, in
which case such company will likely be classified as both a PFIC and an FPHC. In
that event, unless a QEF election is made, you will be required to include the
portion of the foreign corporation's income that is required to be included
under the FPHC rules, described above, and also be subject to tax under the PFIC
rules with respect to gains on disposition and excess distributions, including
the interest charge, as described above. However, if you have made a QEF
election with respect to a company that is treated as both a PFIC and an FPHC,
you will include your proportionate share of the foreign corporation's income as
provided in the FPHC rules, as described above, and any remaining income under
the QEF rules, as described above. Accordingly, you will include your
proportionate share of the subsidiary's income, but only once, and you will not
be subject to the PFIC rules regarding gains from disposition and excess
distributions, including the interest charge described above in the PFIC rules.

     Harbor Global will undertake to obtain from any PFIC, and provide to you,
the information necessary to allow you to make, and maintain, a QEF election
with respect to any PFIC. However, Harbor Global cannot assure you that it will
be able to provide all the necessary information to satisfy the PFIC
requirements or that you will be permitted to make and maintain a QEF election.

     YOU ARE STRONGLY URGED TO CONSULT YOUR TAX ADVISOR WITH RESPECT TO HOW THE
PASSIVE FOREIGN INVESTMENT COMPANY RULES AFFECT YOUR TAX SITUATION AND WHETHER
MAKING A QUALIFIED ELECTING FUND ELECTION WITH RESPECT TO EACH PASSIVE FOREIGN
INVESTMENT COMPANY OWNED BY HARBOR GLOBAL WOULD BE BENEFICIAL TO YOU.

     Controlled Foreign Corporation

     Any foreign corporation that is held directly or indirectly by Harbor
Global could be treated as a "controlled foreign corporation" if more than 50%
of the total voting power or value of the shares is owned, directly or
indirectly, by shareholders that are citizens or residents of the United States,
United States domestic partnerships or corporations or estates or trusts other
than foreign estates or trusts, indirectly owning 10% or more of the total
combined voting power of all classes of shares in the foreign corporation. This
classification would have many complex results, including requiring the
shareholders to include in income their pro rata shares of the controlled
foreign corporation's "Subpart F Income," as defined by the Internal Revenue
Code. In addition, with respect to any such shareholder who is or was a 10% or
greater shareholder at any time during the five year period ending with the sale
or exchange of shares in a controlled foreign corporation by Harbor Global or
any of its subsidiaries, gain from such sale or exchange will be treated as
ordinary dividend income to the extent of the controlled foreign corporation's
earnings and profits attributable to the shares sold or exchanged.

     Pioneer believes that any foreign corporation that will be held directly or
indirectly by Harbor Global immediately following the distribution will not be a
controlled foreign corporation. However, we cannot assure you that a foreign
corporation owned by Harbor Global will not qualify as a controlled foreign
corporation in the future.

     Receipt of Cash on Exercise of Appraisal Rights

     Generally, a Pioneer stockholder who exercises appraisal rights with
respect to the stockholders' shares of Pioneer common stock will recognize
capital gain (or loss) on the receipt of cash from the exercise of appraisal
rights if the stockholders holds his, her or its Pioneer common stock as a
capital asset.

     THE TAX CONSEQUENCES OF THE MERGER AND THE DISTRIBUTION OF HARBOR GLOBAL
COMMON SHARES APPLICABLE TO YOU ARE COMPLEX AND WILL DEPEND ON THE FACTS OF YOUR
PARTICULAR SITUATION. WE URGE YOU TO CONSULT YOUR OWN TAX ADVISOR REGARDING THE
SPECIFIC TAX CONSEQUENCES OF THE MERGER AND THE DISTRIBUTION, INCLUDING TAX
RETURN REPORTING REQUIREMENTS, THE APPLICABILITY OF FEDERAL, STATE, LOCAL AND
FOREIGN TAX LAWS

                                       56
<PAGE>   61

AND THE EFFECT OF ANY PROPOSED CHANGE IN THE TAX LAWS. WE ALSO URGE YOU TO READ
THE TAX DESCRIPTIONS, INCLUDING THE TAX CONSEQUENCES THAT MAY ARISE FROM HOLDING
HARBOR GLOBAL SHARES, DESCRIBED IN HARBOR GLOBAL'S INFORMATION STATEMENT WHICH
IS ATTACHED TO THIS PROXY STATEMENT AS ANNEX B.

DISSENTING STOCKHOLDERS' APPRAISAL RIGHTS

     Section 262 of the Delaware General Corporation Law is attached as Annex E
to this proxy statement and incorporated herein by reference. You should read
Annex E carefully in its entirety for a complete understanding of its terms. If
you wish to exercise statutory appraisal rights or wish to preserve the right to
do so, the failure to comply with the procedures set forth under Section 262
will result in the loss of appraisal right.

     You are entitled to appraisal rights under Section 262 of the Delaware
General Corporation Law and may, instead of accepting the merger consideration
to be issued in the merger, demand the fair value of your shares as determined
by a Delaware court. However, to do so, you must comply with the conditions
established by Section 262, which are complex.

     Here are some of the conditions to preserving and exercising appraisal
rights:

     - you must own the shares of Pioneer common stock for which you demand
       appraisal on the date you deliver the demand for appraisal described
       below;

     - you must continue to own those shares through the closing of the merger;

     - before the vote is taken at the special meeting, you must deliver a
       properly executed written demand for appraisal of your shares to our
       secretary. The demand will be sufficient if you sign it, and it
       reasonably informs us of your identity and your intent to demand an
       appraisal of your shares. Any written demands should be sent to:

               The Pioneer Group, Inc.
               60 State Street
               Boston, Massachusetts 02109
               Attention: Secretary

     - you must NOT have voted in favor of the proposed merger, either in
       person, by proxy or by written consent. You can meet this requirement by
       either not voting or by voting against the merger;

     Important: You must separately comply with each of the last two
requirements listed above. Under Delaware law, to not vote in favor of the
proposed transaction, or to vote against it, is not considered a written demand
for appraisal of your shares.

     - you must file a petition for appraisal of your shares in the Delaware
       Court of Chancery, as more fully described below, within 120 days after
       the closing of the merger;

     - within 20 days after you file your petition with the Delaware Court of
       Chancery, you must send a copy of it to us. Send it to the same address
       to which your written demand is sent (see the third bullet point above);
       and

     - you must satisfy the other conditions described more fully below and in
       Annex E.

     Availability of Information About Other Dissenting Stockholders.  Within 10
days after the closing of the proposed merger, we will notify each stockholder
who has complied with the procedures described above that the merger has become
effective. Within 120 days after the closing of the proposed merger, if you have
complied with the conditions for appraisal of your shares, you may request in
writing, and we will send you, a statement regarding the number of shares of
Pioneer common stock not voted in favor of the transaction, the number of shares
for which we have received a written demand for appraisal and the number of
stockholders who own those shares. We are required to mail this statement to you
within

                                       57
<PAGE>   62

10 days after receiving your request. You should send any such request to the
same address to which your written demand is sent (see the third bullet point
above).

     What You Would Receive by Exercising Appraisal Rights.  If you intend to
demand an appraisal of your shares, keep in mind that the fair value of your
shares as determined under Delaware law could be more than, the same, OR LESS
THAN the merger consideration you would receive if you did not demand an
appraisal of your shares. Section 262 requires the fair value of the shares to
be determined exclusive of any element of value arising from the accomplishment
or expectation of the acquisition. A discussion of the other factors considered
by the Delaware Court of Chancery in appraising your shares is beyond the scope
of this summary.

     Expenses of the Appraisal Proceeding.  The cost of the appraisal proceeding
may be determined by the court and allocated among the parties to the proceeding
as the court deems equitable. Also, on application by a dissenting stockholder,
the court may order that all or a portion of the expenses incurred in the
appraisal proceeding by all dissenting stockholders be charged pro rata against
the value of all shares of stock entitled to appraisal.

     Termination of Rights as a Stockholder.  If you properly demand appraisal
of your shares, you will lose your right to vote those shares on any matter or
to receive payment of dividends or other distributions on such shares. Keep in
mind, however, we do not currently anticipate paying any dividends on Pioneer
common stock.

     Withdrawal of a Demand for Appraisal.  You may withdraw a demand for
appraisal, and accept the consideration received by other stockholders of
Pioneer, at any time within 60 days after the closing of the merger. After this
60-day period has passed, you may not withdraw your demand for appraisal unless
we consent to the withdrawal. If you take all the other actions required to
exercise your appraisal rights but fail to file a petition in the Delaware Court
of Chancery within 120 days after the transaction closes, you will lose your
appraisal rights. However, you then will be entitled to receive the
consideration the other stockholders of Pioneer receive in the transaction.

     The failure to take any step required to preserve or exercise appraisal
rights may result in the loss of those rights. In view of the complexity of
exercising appraisal rights under Delaware law, if you are considering
exercising these rights you should consult with your legal counsel.

                              THE MERGER AGREEMENT

     The following is a brief summary of the material provisions of the merger
agreement, a copy of which is attached as Annex A to this proxy statement and is
incorporated by reference into this summary. The summary description is not
complete and is qualified in its entirety by reference to the merger agreement.
We urge all Pioneer stockholders to read the merger agreement annexed to this
proxy statement in its entirety for a more complete description of the terms and
conditions of the merger and related matters.

GENERAL

     Following the adoption of the merger agreement, approval of the merger by
the Pioneer stockholders and the satisfaction or waiver of the other conditions
to the merger, Pioneer will merge with a wholly-owned subsidiary of UniCredito.
Pioneer will survive the merger as a wholly-owned subsidiary of UniCredito. If
all conditions to the merger are satisfied or waived, the merger will become
effective at the time the surviving corporation files a duly executed
certificate of merger with the Secretary of State of the State of Delaware.

TREATMENT OF PIONEER COMMON STOCK

     At the effective time of the merger, each issued and outstanding share of
Pioneer common stock, other than shares held by stockholders who perfect
appraisal rights, will convert into the right to receive a cash payment of
$43.50. In connection with the merger, Pioneer will distribute to its
stockholders of record immediately prior to the effective time of the merger all
of the equity interest in Harbor Global.

TREATMENT OF UNVESTED RESTRICTED STOCK OF PIONEER

     Prior to the effective time of the merger, each unvested restricted share
of Pioneer common stock granted by Pioneer under the 1995 Restricted Stock Plan
and the Amended and Restated 1997 Stock Incentive Plan will become fully vested.
In the merger, all shares of restricted stock will convert into the right to
receive a cash payment of $43.50. Holders of restricted stock also will receive
Harbor Global common shares in connection with the distribution.

TREATMENT OF PIONEER STOCK OPTIONS

     Prior to the effective time of the merger, each unvested option granted by
Pioneer under Pioneer's Amended and Restated 1997 Stock Incentive Plan and 1988
Stock Option Plan will become fully vested. In the merger, each holder of a
stock option will receive from UniCredito, as soon as practicable following the
effective time of the merger, a cash payment equal to the excess of $43.50 over
the per share exercise price of his or her option, multiplied by the number of
shares subject to such option. Thereafter, all options to purchase Pioneer
common stock will be of no further force or effect.

     Unless they exercise their options prior to the merger, holders of options
will not participate in the distribution of Harbor Global common shares.

EXCHANGE OF CERTIFICATES

     Payment Agent; Payment Procedures; No Further Ownership Rights

     As soon as practicable after the effective time of the merger, UniCredito's
payment agent will mail to each record holder of Pioneer common stock a letter
of transmittal and instructions for surrendering their certificates. Only those
holders who properly surrender their certificates in accordance with the
instructions will receive a cash payment. Upon the surrender of each certificate
with a completed and executed letter of transmittal, UniCredito's payment agent
will pay the stockholder $43.50 multiplied by the number of

                                       59
<PAGE>   64

shares represented by each certificate held by such stockholder, without any
interest. The surrendered certificates representing shares of Pioneer common
stock will then be cancelled.

     HOLDERS OF PIONEER COMMON STOCK SHOULD NOT SEND IN THEIR CERTIFICATES UNTIL
THEY RECEIVE A LETTER OF TRANSMITTAL FROM THE PAYMENT AGENT.

     Lost Certificates

     If any certificate representing shares of Pioneer common stock is lost,
stolen or destroyed, the Pioneer stockholder must provide an appropriate
affidavit of that fact. UniCredito may require the Pioneer stockholder to
deliver a bond as indemnity against any claim that may be made against
UniCredito with respect to such certificates alleged to have been lost, stolen
or destroyed.

       capitalization;

     - make any capital expenditure or commitment for which it is not

       forth in the merger agreement not being satisfied in a material way.

     Pioneer and UniCredito have also agreed to cooperate in obtaining necessary
authorizations and approvals related to the merger from the boards of directors
or trustees of Pioneer's registered investment companies and/or their
stockholders, as required by applicable law.

PIONEER IS RESTRICTED FROM TRYING TO SELL PIONEER TO ANOTHER PARTY

     Pioneer has agreed that neither it nor any of its subsidiaries will,
directly or indirectly through their officers, directors, employees, financial
advisors or agents:

     - solicit, initiate, or encourage any proposal that could reasonably be
       expected to lead to a tender offer for more than 20% of the outstanding
       shares of Pioneer common stock, an exchange offer, merger, consolidation,
       or sale of assets representing more than 20% of the total book value of
       all Pioneer assets;

     - engage or participate in any negotiations or discussions concerning, or
       provide any non-public information to any person or entity relating to,
       any such acquisition proposal; or

     - recommend any such acquisition proposal to the Pioneer stockholders.

     However, Pioneer and the Pioneer board of directors may comply with Rule
14d-9 and Rule 14e-2 promulgated under the Exchange Act with regard to such an
acquisition proposal. In addition, Pioneer and the Pioneer board of directors
may furnish non-public information to, or enter into discussions or negotiations
with, any person or entity in connection with an unsolicited bona fide written
proposal to acquire more than 20% of the outstanding shares of Pioneer common
stock or Pioneer assets having a fair market value equal to more than 20% of the
total book value of all Pioneer assets, enter into an agreement to consummate
any such acquisition and recommend such acquisition to Pioneer stockholders, if
and only to the extent that:

     - the Pioneer board of directors believes in good faith, after consultation
       with its financial advisor(s), that the proposal constitutes a superior
       proposal to this merger and in the best interests of the stockholders;

     - prior to furnishing non-public information to, or engaging in discussions
       or negotiations with a person, that person provides to the Pioneer board
       of directors an executed confidentiality agreement not less favorable
       than the confidentiality agreement between UniCredito and Pioneer; and

     - prior to recommending a superior proposal, Pioneer gives UniCredito five
       business days' prior notice of its intent to recommend the superior
       proposal in order to provide UniCredito an opportunity to make a
       counterproposal which Pioneer and its advisors will negotiate with
       UniCredito during this five day period.

     Pioneer has agreed to notify UniCredito promptly in reasonable detail of
receipt of any acquisition proposal or request for non-public information.
Pioneer has agreed to continue to keep UniCredito

                                       62
<PAGE>   67

informed on a current basis of the status of any discussions or negotiations and
all material terms being discussed or negotiated.

DIRECTOR AND OFFICER INDEMNIFICATION

     The merger agreement provides that for a period of six years after the
effective time of the merger, UniCredito will continue all rights to
indemnification, advancement of expenses, exculpation, limitation of liability,
and any similar rights, existing at the time of the merger in favor of the
employees, agents, directors or officers of Pioneer. UniCredito has also agreed
to provide each individual who served as a director or officer of Pioneer at any
time prior to the merger with liability insurance for a period of six years
after the merger no less favorable in coverage and amount than was in effect
prior to the merger.

CONDITIONS TO OBLIGATIONS TO EFFECT THE MERGER

     The obligations of UniCredito and Pioneer to effect the merger are subject
to the satisfaction or waiver of the following conditions:

     - the Pioneer stockholders must have approved and adopted the merger
       agreement and the merger;

     - all applicable waiting periods, and any extensions of these periods,
       under the Hart-Scott-Rodino Antitrust Improvements Act and the EC
       Regulation must have expired or been terminated;

     - the parties must have obtained certain authorizations and consents;

     - there must be no order, executive order, stay, decree, judgment or
       injunction, or statute, rule or regulation in effect that makes the

     - the distribution of Harbor Global shares to the Pioneer stockholders
       shall have been completed;

     - the merger agreement and the merger shall have been approved by the Bank
       of Italy; and

     - either UniCredito shall have qualified as a "financial holding company"
       under the Bank Holding Company Act or the merger shall have been approved
       under the Bank Holding Company Act by the Board of Governors of the U.S.
       Federal Reserve System.

     In addition, the obligation of Pioneer to effect the merger is subject to
the satisfaction or waiver of the following conditions:

     - the representations and warranties of UniCredito and its wholly-owned
       subsidiary in the merger agreement must be true and correct as of the
       effective time of the merger, unless made as of another date, in which
       case they must be true as of such date and except where the failure to be
       true and correct does not, and is not reasonably likely to, have a
       material adverse effect on UniCredito; and

     - UniCredito and its wholly-owned subsidiary must have performed in all
       material respects all obligations required to be performed by them under
       the merger agreement at or prior to the effective time of the merger.

     In addition, the obligations of UniCredito and its wholly-owned subsidiary
to effect the merger are subject to the satisfaction or waiver of the following
conditions:

     - the representations and warranties of Pioneer in the merger agreement
       must be true and correct as of the effective time of the merger, unless
       made as of another date, in which case they must be true and correct as
       of such date and except where the failure to be true and correct does
       not, and is not reasonably likely to have a material adverse effect on
       Pioneer, provided, however, that any untrue statements are not the result
       of intentional fraudulent conduct of Pioneer;

                                       63
<PAGE>   68

     - Pioneer must have performed in all material respects all obligations

       the effective time of the merger;

     - the number of shares held by stockholders exercising appraisal rights
       does not exceed 15% of the total of outstanding shares of Pioneer common
       stock; and

       States registered investment companies shall have been approved by United
       States registered investment companies representing at least 92.5% of the
       assets under management of all such funds.

TERMINATION; EXPENSES AND TERMINATION FEES

     The merger agreement may be terminated by written notice from the
terminating party under the following circumstances at any time prior to the
effective time of the merger:

     - by mutual written consent of the parties;

     - by either Pioneer or UniCredito if the merger is not completed by
       February 15, 2001, unless the delay is due to the terminating party's
       failure to fulfill any obligation under the merger agreement;

     - by either UniCredito or Pioneer if at the special meeting of Pioneer
       stockholders, Pioneer does not obtain the requisite vote of its
       stockholders in favor of the merger agreement;

     - by UniCredito, if (1) the Pioneer board of directors fails to recommend
       approval of the merger to the Pioneer stockholders or withdraws or
       modifies its recommendation; (2) the Pioneer board of directors
       recommends to the Pioneer stockholders an alternative transaction with
       another person or entity meeting the requirements set forth in the merger
       agreement; or (3) a third party commences a tender offer or exchange
       offer for 20% or more of the outstanding shares of Pioneer common stock
       and the Pioneer board of directors fails to recommend that the Pioneer
       stockholders reject the offer or takes no position with respect to the
       offer; or

     - by either UniCredito or Pioneer, if there has been a breach of the
       representations, warranties, covenants or agreements by the other party
       so that the conditions to closing are not being satisfied which is not
       curable or which is curable but such party does not make reasonable
       efforts to cure.

     In the event the merger agreement is terminated due to a breach of any
representation, warranty, covenant or agreement as described above, the party in
breach shall reimburse the other party all reasonable costs and expenses
incurred by it in connection with the merger agreement and the merger.

     If either UniCredito or Pioneer terminates the merger agreement because of
any of the reasons above, all obligations of the parties under the merger
agreement will terminate (with certain exceptions) and there will be no
liability, except for any liability for willful breaches of the merger agreement
on the part of UniCredito, Pioneer, UniCredito's wholly-owned subsidiary or
their respective officers, directors, stockholders or affiliates. The mutual
confidentiality agreement dated March 23, 2000 between UniCredito and Pioneer
will survive any termination of the merger agreement.

     Except as described below, UniCredito and Pioneer will bear their own
expenses incurred in connection with the merger.

     Pioneer has agreed to pay UniCredito a $37,500,000 termination fee if the
merger agreement is terminated under the following circumstances:

     - by UniCredito, because (1) the Pioneer board of directors fails to
       recommend approval of the merger to the Pioneer stockholders or withdraws
       or modifies its recommendation; (2) the Pioneer board of directors
       recommends to the Pioneer stockholders an alternative transaction with
       another

                                       64
<PAGE>   69

       person or entity meeting the requirements set forth in the merger
       agreement; or (3) a third party commences a tender offer or exchange
       offer for 20% or more of the outstanding shares of Pioneer common stock
       and the Pioneer board of directors fails to recommend that the Pioneer
       stockholders reject the offer or takes no position with respect to the
       offer; or

     - by UniCredito or Pioneer because Pioneer fails to obtain the requisite
       vote of Pioneer stockholders to approve the merger agreement and Pioneer
       consummates a sale of the company within 18 months of such termination.

RELATED MATTERS AFTER THE MERGER

     At the time of the merger, a subsidiary of UniCredito will be merged with
Pioneer. Pioneer will become the surviving corporation in the merger and a
wholly-owned subsidiary of UniCredito. Each share of the subsidiary's common
stock issued and outstanding immediately prior to the merger will be converted
into one validly issued, fully paid and nonassessable share of common stock of
the surviving corporation. The certificate of incorporation of the subsidiary,
in effect immediately prior to the time of the merger, will become the
certificate of incorporation of the surviving corporation, except that the name
shall be Pioneer Global Asset Management. The by-laws of the subsidiary will
become the by-laws of the surviving corporation, except that the name shall be
changed to the name of Pioneer Global Asset Management.

     The merger is intended to qualify for the treatment described in Section
15(f) of the U.S. Investment Company Act of 1940, as amended. In this regard,
UniCredito shall, (i) use reasonable efforts to assure that, for a period of
three years after the effective time of the merger, at least 75% of the board of
directors or trustees of each registered investment company are not "interested
persons" of Pioneer or UniCredito, as that term is defined under the Investment
Company Act; and (ii) refrain from imposing, for a period of two years after the
effective time of the merger, any "unfair burden" on any registered investment
company, within the meaning of the Investment Company Act.

     UniCredito has agreed for a period of at least 12 months following the
effective time of the merger to:

     - provide each continuing employee cash compensation that is no less
       favorable to the employee than the compensation prior to the effective
       time; and

     - maintain employee benefit plans and arrangements, other than stock
       incentive plans, that are no less favorable than the benefit arrangements
       in effect prior to the effective time.

     The forgoing is not intended to restrict UniCredito from terminating the
employment of any employee.

AMENDMENT

     Prior to obtaining approval of the merger agreement from the Pioneer
stockholders, Pioneer and UniCredito may agree in writing to amend the merger
agreement. Any amendment which would reduce the cash payment to the Pioneer
stockholders or which would be materially adverse to the Pioneer stockholders
must also be approved by the Pioneer stockholders.

         RELATIONSHIPS AND TRANSACTIONS BETWEEN UNICREDITO AND PIONEER

     Except as described under "The Merger -- Background to the Merger," there
have been no negotiations, transactions or material contacts between UniCredito
and Pioneer concerning a merger, an acquisition of Pioneer's common stock, a
tender offer for Pioneer's common stock, the sale of Pioneer's assets or the
election of Pioneer's directors during the past two years.

     There are currently no present or proposed material agreements,
arrangements or understandings between UniCredito, or any of its affiliates, and
Pioneer. If Pioneer becomes a wholly-owned subsidiary of UniCredito, it is
possible that agreements, such as subadvisory arrangements between Pioneer and
EuroPlus, may be entered into between Pioneer and UniCredito and its affiliates
that may be material to Pioneer.

     Pioneer and Harbor Global have entered into a distribution agreement and
tax separation agreement that relate, among other things, to the transfer of
assets to Harbor Global, Pioneer's distribution of Harbor Global's common shares
to Pioneer stockholders, the allocation of certain tax liabilities between
Pioneer and Harbor Global, certain indemnification obligations between Harbor
Global and Pioneer and the provision by Pioneer of certain services to Harbor
Global on a temporary basis. These arrangements will remain in effect after the
effective time of the merger. In addition, Pioneer and Harbor Global may enter
into an agreement for the provision of some corporate administrative,
information and technology systems, human resources and other support to Harbor
Global for a limited transition period. To find out more about these agreements,
see Harbor Global's information statement attached as Annex B to this proxy
statement.

                             STOCKHOLDER PROPOSALS

     If the proposed merger is completed, there will be no public stockholders
of Pioneer and no public participation in any future meetings of Pioneer
stockholders. If the proposed merger is not completed, Pioneer intends to hold
its next annual meeting of stockholders in May 2001. In that case, Pioneer's
stockholders would continue to be entitled to attend and participate in
Pioneer's stockholders meetings.

     Pioneer will consider appropriate stockholder proposals for inclusion on
the agenda of its 2001 annual meeting of stockholders. Proposals of stockholders
made in accordance with Rule 14a-8 of the Exchange Act, and intended to be
presented at the 2001 annual meeting must be submitted in writing to the
attention of the chief financial officer of The Pioneer Group, Inc., 60 State
Street, Boston, Massachusetts 02109 no later than December 15, 2000 for
inclusion in the proxy statement for that meeting. In addition, Pioneer's
by-laws require that Pioneer be given advance notice of stockholder nominations
for election to the board of directors and of other matters which stockholders
wish to present for action at an annual meeting of stockholders (other than
matters included in Pioneer's proxy statement in accordance with Rule 14a-8).
The required notice must be made in writing, include the information required by
the by-laws, be delivered or mailed by first class United States mail, postage
prepaid, to the chief financial officer of The Pioneer Group, Inc., 60 State
Street, Boston, Massachusetts 02109, and be received not less than 60 days nor
more than 90 days prior to the 2001 annual meeting; provided, however, that if
less than 70 days notice or prior public disclosure of the date of the meeting
is given to stockholders, such nomination or other proposal shall have been
mailed or delivered to the chief financial officer of Pioneer not later than the
close of business on the 10th day following the date on which the notice of the
meeting was mailed or such public disclosure made, whichever occurs first. While
Pioneer has not set the date of the 2001 annual meeting, assuming it was held on
May 16, 2001 (the same day as this year's meeting), notice of a stockholder
proposal or director nomination would need to be made no earlier than February
15, 2001 and no later than March 17, 2001.

                          AGREEMENT AND PLAN OF MERGER

     THIS AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated as of May 14,
2000, is between UniCredito Italiano S.p.A., a corporation organized under the
laws of the Republic of Italy (the "Parent"), and The Pioneer Group, Inc., a
corporation organized under the laws of the State of Delaware (the "Company").

                                   BACKGROUND

     A. The respective Boards of Directors of the Parent and the Company have
each duly approved the merger of a corporation to be organized under the laws of
the State of Delaware and to be a wholly owned subsidiary of the Parent (the
"Purchaser") with and into the Company on the terms and subject to the
conditions of this Agreement (the "Merger") and the Board of Directors of the
Company has resolved to recommend approval of the Merger by the Stockholders.

     B. In addition to receiving the Cash Consideration provided for in this
Agreement, the Stockholders are receiving Harbor Global Interests in connection
with the Merger.

     C. The respective Boards of Directors of the Parent and the Company have
each duly approved all of the other transactions contemplated by this Agreement.

     D. In order to induce Parent to enter into this Agreement, certain
Stockholders who are executive officers of the Company (the "Management
Stockholders") and the Parent have simultaneously herewith entered into voting
agreements, whereby such Management Stockholders have agreed, among other
things, to vote in favor of this Agreement, the Merger and the other
transactions contemplated hereby.

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
herein contained and for other good and valuable consideration the receipt and
adequacy of which are hereby acknowledged, the Parent, the Purchaser and the
Company hereby agree as follows:

                                   ARTICLE 1

                                   THE MERGER

     1.1  The Merger.  (a) At the Effective Time (as hereinafter defined), in
accordance with this Agreement and the General Corporation Law of the State of
Delaware ("Delaware Law"), the Purchaser shall be merged with and into the
Company, the separate existence of the Purchaser shall cease and the Company
shall continue as the surviving corporation. Notwithstanding the foregoing, the
Parent may elect, prior to the Merger, instead of merging Purchaser with and
into the Company, as provided above, to merge the Company with and into the
Purchaser; provided, that the Company shall not be deemed to have breached any
of its representations, warranties or covenants set forth in this Agreement, and
no closing condition contained herein shall be deemed not satisfied, solely by
reason of such election. The Company (or in the case of an election by the
Parent pursuant to the immediately preceding sentence, the Purchaser) is
hereinafter sometimes referred to as the "Surviving Corporation."

     (b) Notwithstanding anything in the Agreement to the contrary, the Parent
may identify certain assets owned by the Company (including stock of the
Continuing Subsidiaries) or assets owned by the Continuing Subsidiaries (the
"Designated Assets") that the Parent desires to purchase directly, or that the
Parent desires one of its affiliates to purchase. In such event, the Company and
the Parent (or such affiliate of the Parent) shall negotiate in good faith a
purchase and sale agreement with respect to the Designated Assets; provided,
however, that the Company shall be under no obligation to enter into any such
agreement. Any purchase and sale agreement with respect to the Designated Assets
shall close simultaneously with the Effective Time, on such terms (including
appropriate indemnities provided by the Parent for liabilities arising from such
sale) arrived at between the parties in good faith. If the Parent so

                                       A-1
<PAGE>   85

directs, the net proceeds from such sale of assets shall be used as part of the
Cash Consideration and will reduce the other Cash Consideration provided by the
Parent such that the Stockholders shall receive the same aggregate Cash
Consideration provided for herein as if the Parent had not so directed the use
of such net proceeds.

     1.2  Effect of the Merger.  At the Effective Time, the Surviving
Corporation shall continue its corporate existence under the laws of the State
of Delaware and the Merger shall have the effects set forth in Section 251 of
the Delaware Law.

     1.3  Consummation of the Merger.  As soon as is practicable after the
satisfaction or waiver of the conditions set forth in Article 6 hereof, the
parties hereto will cause the Merger to be consummated by delivering to the
Secretary of State of the State of Delaware a Certificate of Merger (the
"Certificate of Merger") in such form or forms as may be required by, and
executed and acknowledged in accordance with, the relevant provisions of the
Delaware Law, and shall make all other filings and recordings required by the
Delaware Law in connection with the Merger. The Merger shall become effective at
the time that the Certificate of Merger is filed with the Secretary of the State
of the State of Delaware in accordance with the relevant provisions of the
Delaware Law (or at such later time, which shall be as soon as reasonably
practicable, specified as the effective time in the Certificate of Merger). The
term "Effective Time" shall mean the date and time of the filing of the
Certificate of Merger with the Secretary of the State of the State of Delaware
(or such later time, which shall be as soon as reasonably practicable, as may be
specified in the Certificate of Merger).

     1.4  Certificate of Incorporation; By-Laws; Directors and Officers.  The
Certificate of Incorporation and By-laws of the Purchaser as in effect
immediately prior to the Effective Time shall be the Certificate of
Incorporation and By-laws of the Surviving Corporation until thereafter amended
as provided under the Delaware Law, except that (1) the name of the corporation
set forth therein shall be changed to the name of the Company and (2) the
identity of the incorporator set forth in the Certificate of Incorporation shall
be deleted. The directors of the Purchaser immediately prior to the Effective
Time will be the initial directors of the Surviving Corporation, and the
officers of the Company immediately prior to the Effective Time will be the
initial officers of the Surviving Corporation, in each case until such time as
changed in accordance with the provisions of Delaware Law and the By-laws of the
Surviving Corporation or until their successors are duly elected and qualified.

     1.5  Conversion of Securities.

     (a) At the Effective Time, by virtue of the Merger and without any action
on the part of the Purchaser, the Company, the Surviving Corporation or the
holder of any of the following securities:

          (i) subject to Section 1.5(b), (A) each share of the Company's common
     stock, par value $0.10 per share (the "Shares"), issued and outstanding
     immediately prior to the Effective Time (other than Shares to be cancelled
     pursuant to clause (ii) below and any Dissenting Shares (as defined below))
     and (B) the 35,958 Shares held in the treasury pursuant to a deferred
     compensation arrangement (the "Deferred Compensation Shares"), which on or
     prior to the Effective Time shall for purposes of this Agreement be deemed
     to be held by the beneficiary of said deferred compensation arrangement,
     shall in the case of clauses (A) and (B) be cancelled and extinguished or
     retired and be converted into and become a right to receive $43.50 in cash
     per Share without any interest thereon (the "Cash Consideration");

          (ii) each Share held in the treasury of the Company (other than as
     provided in clause (i)(B) above) and each Share that is issued and
     outstanding immediately prior to the Effective Time and owned by the
     Parent, the Purchaser or the Company or any direct or indirect subsidiary
     of the Parent, the Purchaser or the Company, shall be cancelled and
     retired, and no payment shall be made with respect thereto; and

                                       A-2
<PAGE>   86

          (iii) each share of the Purchaser's capital stock issued and
     outstanding immediately prior to the Effective Time shall be converted into
     and become one validly issued, fully paid and nonassessable share of common
     stock of the Surviving Corporation.

     (b) Notwithstanding Section 1.5(a), Shares outstanding immediately prior to
the Effective Time and held by a holder who, acting in accordance with Section
262 of Delaware Law, (A) prior to the meeting at which the Company's
stockholders (the "Stockholders") vote to approve the Merger, has delivered to
the Company written notice of such holder's intention to demand payment for his
Shares if the Merger is effectuated and (B) has not voted in favor of the Merger
("Dissenting Shares"), shall not be converted into a right to receive the Cash
Consideration, unless such holder withdraws or otherwise loses his right to
demand payment for his Shares. If, after the Effective Time, such holder
withdraws or loses his right to demand payment for his Shares, such Shares shall
be treated as if they had been converted as of the Effective Time into the right
to receive the Cash Consideration payable in respect of such Shares pursuant to
Section 1.5(a)(i).

     (c) The Company shall give the Parent and the Purchaser prompt notice of
any demands for payment, or notices of intent to demand payment, received by the
Company with respect to Shares in accordance with Section 262 of Delaware Law,
and the Parent and the Purchaser shall have the right to participate in all
negotiations and proceedings with respect to such demands. The Company shall
not, except with the prior written consent of the Parent and the Purchaser or as
otherwise required by law or pursuant to a final order of a court of competent
jurisdiction, make any payment with respect to, or settle, or offer to settle,
any such demands.

     1.6  Company Stock Options and Plans.  The Company shall take all actions
necessary to ensure that (a) all Options (as defined in Section 3.3 below)
outstanding under the Plans (as defined in Section 3.3 below), to the extent not
exercised prior to the Effective Time, shall, if not currently vested, be fully
vested immediately prior to the Effective Time and shall terminate and be
cancelled as of the Effective Time and in consideration thereof each holder
shall receive from the Purchaser, as soon as practicable following the Effective
Time, a cash payment equal to the excess of the Cash Consideration (if any) over
the per share exercise price of such Option, multiplied by the number of shares
subject to such Option (as the case may be), and thereafter such Options shall
be of no further force or effect, (b) all restricted common stock granted under
any Plan shall, if not currently vested, be fully vested immediately prior to
the Effective Time and (c) all Plans shall terminate as of the Effective Time.
Any such payment shall be subject to all applicable federal, state and local tax
withholding requirements.

     1.7  Exchange of Certificates.

     (a) From and after the Effective Time, a bank or trust company to be
designated by the Parent or the Purchaser and consented to by the Company (such
consent not to be unreasonably withheld, delayed or conditioned) (the "Payment
Agent") shall act as payment agent in effecting the exchange, for the Cash
Consideration multiplied by the number of Shares formerly represented thereby,
of certificates (the "Certificates") that, prior to the Effective Time,
represented Shares entitled to payment pursuant to Section 1.5(a)(i). From time
to time, the Parent shall, or shall cause the Purchaser to, deposit with the
Payment Agent in trust for the benefit of the holders of Certificates, such
amount of the Cash Consideration in immediately available funds needed to pay
promptly for surrendered Shares as provided in this Section 1.7 (the "Payment
Fund"). Promptly after the Effective Time (but in any event within two business
days thereof), the Payment Agent shall mail to each record holder of
Certificates that immediately prior to the Effective Time represented Shares a
form of letter of transmittal (in form and substance reasonably satisfactory to
the Parent) and instructions for use in surrendering such Certificates and
receiving the Cash Consideration therefor. Upon the surrender of each such
Certificate together with a duly completed and executed letter of transmittal,
the Payment Agent shall pay the holder of such Certificate the Cash
Consideration multiplied by the number of Shares formerly represented by such
Certificate, without any interest thereon, in exchange therefor, and such
Certificate shall forthwith be cancelled. Delivery shall be effected, and risk
of loss and title to the Certificate shall pass, only upon

                                       A-3
<PAGE>   87

proper delivery of the Certificate to the Payment Agent, and the letter of
transmittal shall so reflect. Until so surrendered and exchanged, each such
Certificate (other than Certificates representing Shares held by the Parent, the
Purchaser or the Company or any direct or indirect subsidiary of the Parent, the
Purchaser or the Company or Dissenting Shares) shall represent solely the right
to receive the Cash Consideration multiplied by the number of Shares represented
by such Certificate, without any interest thereon. If any cash is to be paid to
a person other than the holder in whose name the Certificate representing Shares
surrendered in exchange therefor is registered, it shall be a condition to such
payment that the person requesting such payment shall pay to the Payment Agent
any transfer or other taxes required by reason of the payment of such cash to a
person other than the registered holder of the Certificate surrendered, or such
person shall establish to the satisfaction of the Payment Agent that such tax
has been paid or is not applicable. Notwithstanding the foregoing, neither the
Payment Agent nor any party hereto shall be liable to a holder of Shares for any
Cash Consideration delivered to a public official pursuant to applicable
abandoned property, escheat and similar laws.

     (b) To the extent not immediately required for payment for surrendered
Shares as provided in Section 1.7(a), the Payment Fund shall be invested by the
Payment Agent, as directed by the Parent (so long as such directions do not
impair the rights of holders of Shares), in direct obligations of the United
States of America, obligations for which the full faith and credit of the United
States of America is pledged to provide for the payment of principal and
interest, commercial paper rated of the highest quality by Moody's Investors
Services, Inc. or Standard & Poor's Ratings Group, or certificates of deposit
issued by a commercial bank having at least $300,000,000 in assets (a "Qualified
Commercial Bank"); and any net earnings with respect thereto shall be paid to
the Parent as and when requested by the Parent.

     (c) The Payment Agent shall, pursuant to irrevocable instructions, make the
payments referred to in Section 1.5(a)(i) out of the Payment Fund. Promptly
following the date that is nine months after the Effective Time, the Payment
Agent shall deliver to the Parent all cash, certificates and other documents in
its possession relating to the transactions described in this Agreement, and the
Payment Agent's duties shall terminate. Thereafter, each holder of a Certificate
formerly representing a Share may surrender such Certificate to the Surviving
Corporation or the Parent and (subject to applicable abandoned property, escheat
and similar laws) receive in exchange therefor the Cash Consideration, without
any interest thereon but shall have no greater rights against the Surviving
Corporation or the Parent than may be accorded to general creditors of the
Surviving Corporation or the Parent under applicable law.

     (d) After the Effective Time, there shall be no transfers on the stock
transfer books of the Surviving Corporation of any Shares. If, after the
Effective Time, Certificates formerly representing Shares are presented to the
Surviving Corporation or the Payment Agent, they shall be cancelled and
exchanged for the Cash Consideration, as provided in this Article 1, subject to
applicable law in the case of Dissenting Shares.

     (e) From and after the Effective Time, holders of certificates theretofore
evidencing Shares shall cease to have any rights as Stockholders, except as
provided herein or by law. After the Effective Time, the Surviving Corporation
shall be entitled to cause the Shares to be delisted from the Nasdaq Stock
Market(R).

     (f) Each of the Surviving Corporation and the Parent shall be entitled to
deduct and withhold from the consideration otherwise payable pursuant to this
Agreement to any holder of Shares such amounts as it is required to deduct and
withhold with respect to the making of such payment under the Internal Revenue
Code of 1986, as amended (the "Code"), or any provision of state, local or
foreign tax law (other than any such tax that may arise due to the status of the
Parent as a non-U.S. corporation). To the extent that amounts are so withheld by
the Surviving Corporation or the Parent, as the case may be, such withheld
amounts shall be treated for all purposes of this Agreement as having been paid
to the holder of the Shares in respect of which such deduction and withholding
was made by the Surviving Corporation or the Parent, as the case may be, and
shall promptly be paid by the Parent or the Purchaser, as the case may be, to
the applicable taxing authority.

     (g) If any Certificate shall have been lost, stolen or destroyed, upon the
making of an affidavit of that fact by the person claiming such Certificate to
be lost, stolen or destroyed and, if required by the Surviving Corporation, the
posting by such person of a bond, in such commercially reasonable amount and on
such commercially reasonable terms as the Surviving Corporation may direct, as
indemnity against any claim that may be made against it with respect to such
Certificate, the Parent shall issue in exchange for such lost, stolen or
destroyed Certificate, the Cash Consideration.

     (h) Except for the distribution of shares of Harbor Global contemplated by
Article 8, the Cash Consideration shall be appropriately adjusted to reflect any
stock split, reverse stock split, stock dividend, recapitalization, exchange,
subdivision, combination of, or other similar change in the Shares that shall be
effective or be authorized after the date of this Agreement and prior to the
Effective Time.

understandings or arrangements by which any Continuing Subsidiary is bound to

sanctuaries and wetlands, including without limitation all endangered and
threatened species; (vi) storage tanks, vessels and containers; (vii)
underground and other storage tanks or vessels, abandoned, disposed or discarded
barrels, containers and other closed receptacles; (viii) health and safety of
employees and other persons; and (ix) manufacture, processing, use,
distribution, treatment, storage, disposal, transportation or handling of
pollutants, contaminants, chemicals or industrial, toxic or hazardous substances
or oil or petroleum products or solid or hazardous waste. As used above, the
terms "release" and "environment" shall have the meaning set forth in the
federal Comprehensive Environmental Compensation, Liability and Response Act of
1980 ("CERCLA").

     (b) There have been no releases of any Materials of Environmental Concern
(as defined below) into the environment by the Company or any of its Continuing
Subsidiaries, or, to the knowledge of the Company, by any other party at any
parcel of real property or any facility formerly or currently owned, operated or
controlled by the Company or any of its Continuing Subsidiaries which,
individually or in the aggregate, would reasonably be expected to have a Company
Material Adverse Effect. With respect to any such releases of Materials of
Environmental Concern, the Company has given all notices required to be given by
the Company or any of its Continuing Subsidiaries to Governmental Entities
(copies of which have been provided to the Parent). The Company is not aware of
any releases of Materials of Environmental Concern at parcels of real property
or facilities other than those owned, operated or controlled by the Company or
any of its Continuing Subsidiaries that would, individually or in the aggregate,
have a material impact on the real property or facilities owned, operated or
controlled by the Company or any of its Subsidiaries. For purposes of this
Agreement, "Materials of Environmental Concern" means any chemicals, pollutants
or contaminants, hazardous substances (as such term is defined under CERCLA),
solid wastes and hazardous wastes (as such terms are defined under the federal
Resources Conservation and Recovery Act), toxic materials, oil or petroleum and
petroleum products, or any other material subject to regulation under any
Environmental Law.

     (c) Section 3.10(c) of the Disclosure Schedule describes all environmental
reports, investigations and audits conducted by or on behalf of the Company or
any of its Continuing Subsidiaries or, to the knowledge of the Company,
conducted by or on behalf of a third party (whether done at the initiative of
the Company or any of its Continuing Subsidiaries or directed by a Governmental
Entity or other third party) issued or conducted during the past five years
relating to premises currently or previously owned or operated by the Company or
any of its Continuing Subsidiaries. Complete and accurate copies of each such
report, or the results of each such investigation or audit, have been provided
to the Parent if in the possession or control of the Company.

     (d) The Parties agree that the only representations and warranties of the
Company herein as to any environmental matters are those contained in this
Section 3.10.

     3.11  Employee Benefits and Contracts.

     (a) Neither the Company nor any of its Continuing Subsidiaries is a party
to any collective bargaining agreement.

     (b) Section 3.11(b) of the Disclosure Schedule lists all material employee
benefit plans (as defined in Section 3(3) of the U.S. Employee Retirement Income
Security Act of 1974, as amended ("ERISA")) and all bonus, stock option, stock
purchase, restricted stock, incentive, deferred compensation, retiree medical or
life insurance, supplemental retirement, severance or other benefit plans,
programs or arrangements, and all employment, termination, severance or other
contracts or agreements, whether legally enforceable or not, to which the
Company or any Continuing Subsidiary is a party, with respect to which the
Company or any Continuing Subsidiary has any obligation or which are maintained,
contributed to or sponsored by the Company or any Continuing Subsidiary for the
benefit of any employee, officer or director or former employee, officer or
director of the Company or any Continuing Subsidiary maintained by the Company
or any Continuing Subsidiary. Each of such employee benefit plans complies in
all material respects with all requirements of applicable law. No "prohibited
transaction" (as such term

                                      A-12
<PAGE>   96

is defined in ERISA) has occurred with respect to any such plan which will
result in material liability to the Company.

     (c) Neither the Company nor any affiliate thereof has ever maintained an
employee benefit plan subject to Section 412 of the Code or Title IV of ERISA.
Each employee benefit plan of the Company or any affiliate intended to be
qualified under Section 401(a) of the Code has received a favorable
determination letter from the Internal Revenue Service confirming such
qualification and nothing has occurred that would cause such qualified status to
be jeopardized. Neither the Company nor any affiliate has ever had an obligation
to contribute to a "multiemployer plan" as defined in Section 4001(a)(3) of
ERISA. There are no unfunded obligations under any employee benefit plan of the
Company or any affiliate providing benefits after termination of employment to
any employee, officer or director or former employee, officer or director,
including but not limited to retiree health coverage and deferred compensation,
but excluding continuation of health coverage required to be continued under
Section 4980(B) of the Code. Each employee benefit plan of the Company or any
affiliate may be amended or terminated by the Company or such affiliate without
the consent or approval of any other person. Except as set forth herein, there
is no employee benefit plan, stock option plan, stock appreciation right plan,
restricted stock plan, stock purchase plan, or severance benefit plan of the
Company or any affiliate, any of the benefits of which will be increased or the
vesting of the benefits under which will be accelerated by the occurrence of any
of the transactions contemplated by this Agreement or the benefits under which
will be calculated on the basis of the transactions contemplated by this
Agreement.

     (d) Except for acceleration of vesting of Options and restricted common
stock under the Plans, which the Company represents will not exceed $60,500,000
and $27,500,000, respectively, neither the Company nor any Subsidiary is
obligated to make any parachute payment, as defined in Section 280G(b)(2) of the
Code but without regard to Section 280G(b)(4) of the Code, nor will any
parachute payment be deemed to have occurred as a result of or arising out of
any of the transactions contemplated by this Agreement. Except for acceleration
of vesting of Options and restricted common stock under the Plans, the Company
has no contract, agreement, obligation or arrangement with any employee or other
person, any of the benefits of which will be increased or the vesting of the
benefits under which will be accelerated by any change of control of the Company
or the occurrence of any of the transactions contemplated by this Agreement or
the benefits under which will be calculated on the basis of the transactions
contemplated by this Agreement.

     3.12  Real Property and Leases; Liens on Assets.

     (a) The Company and its Continuing Subsidiaries have sufficient title to
all their properties and assets to conduct their respective businesses as
currently conducted, with only such exceptions as would not, individually or in
the aggregate, reasonably be expected to have a Company Material Adverse Effect.

     (b) The assets, including any real property in which the Company or any of
its Continuing Subsidiaries has an interest, reflected in the balance sheet of
the Company for the fiscal year ended December 31, 1999 included in the
Company's Annual Report on Form 10-K (the "Balance Sheet") or acquired in the
ordinary course of business since December 31, 1999 (the "Assets") (except those
Assets sold or disposed of in the ordinary course of business for full and fair
consideration), (i) are free and clear of all mortgages, security interests,
pledges, liens and encumbrances (collectively, "Encumbrances") other than (A) as
reflected in the Balance Sheet, (B) Encumbrances on assets which, individually
or in the aggregate, are not material to the Company and its Continuing
Subsidiaries, taken as a whole, and (C) liens for state and local property taxes
not in arrears and liens arising by operation of law and (ii) are neither
subject to any governmental decree or order to be sold nor are being condemned,
expropriated or otherwise taken by any public authority with or without payment
or compensation therefor, nor, to the knowledge of the Company, has any such
condemnation, expropriation or taking been proposed, except as would not,
individually or in the aggregate, reasonably be expected to have a Company
Material Adverse Effect.

                                      A-13
<PAGE>   97

     (c) Section 3.12(c) of the Disclosure Schedule lists all leases of real
property leased for the use or benefit of the Company or any Continuing
Subsidiary to which the Company or any Continuing Subsidiary is a party, and all
amendments and modifications thereto (the "Leases"). All Leases are in full
force and effect and have not been modified or amended, and there exists no
default under any such lease by the Company or any Continuing Subsidiary, nor
any event which with notice or lapse of time or both would constitute a default
thereunder by the Company or any Continuing Subsidiary, except as would not,
individually or in the aggregate, reasonably be expected to have a Company
Material Adverse Effect.

     3.13  Taxes.

     (a) The Company and each Subsidiary have timely filed all material tax
returns, statements, reports and forms required to be filed with any tax
authority having jurisdiction over the Company or any Continuing Subsidiary
(collectively, "Tax Returns") and have paid when due all taxes owed by the
Company and any Subsidiary (whether or not shown on any such Tax Returns) to any
such tax authority. There are no liens on any of the assets of the Company or
any Continuing Subsidiary that arose in connection with any failure (or alleged
failure) to pay any tax except for liens that would, individually or in the
aggregate, not reasonably be expected to have a Company Material Adverse Effect.

     (b) No dispute or claim concerning any tax liability of the Company or any
Subsidiary has been claimed or raised by any authority in writing nor to the
Company's knowledge, otherwise.

     (c) Neither the Company nor any Continuing Subsidiary has waived any
statute of limitations in respect of taxes or agreed to any extension of time
with respect to a tax assessment or deficiency.

     (d) Neither the Company nor any Subsidiary has filed a consent under
Section 341(f) of the Code concerning collapsible corporations. Neither the
Company nor any Subsidiary has any liability for the taxes of any person (other
than the Company and the Continuing Subsidiaries) under Treas. Reg. Section
1.1502-6 (or any similar provision of state, local or foreign law), as a
transferee or successor, by contract, or otherwise.

     (e) (i) For United States federal income tax purposes, neither the Company,
nor any Subsidiary nor any Fund is expected to have any income reportable for a
period ending after the Effective Time but attributable to a transaction, such
as an installment sale, occurring in, or a change in method of accounting made
for, a period ending on or prior to the Effective Time that resulted in a
deferred reporting of income from such transaction or from such change in method
of accounting (other than a deferred intercompany transaction); (ii) immediately
after the Merger, neither the Company nor any Subsidiary will be a United States
real property holding corporation within the meaning of Section 897(c)(3) of the
Code; (iii) the Company has provided or made available to the Parent a copy of
any tax-sharing or allocation agreement or arrangement involving the Company or
any of its Continuing Subsidiaries or between a Harbor Global Entity and the
Parent or any Continuing Subsidiary and a description of any such unwritten or
informal agreement or arrangement; (iv) all Taxes required to be withheld,
collected or deposited by the Company or any Subsidiary or Fund have been timely
withheld, collected or deposited and, to the extent required, have been paid to
the relevant Tax authority; (v) except for the transaction contemplated by this
Agreement, neither the Company nor any Subsidiary has engaged in any "deferred
intercompany transactions" within the meaning of Section 1.1502-13 of the
regulations under the Code, and all "intercompany transactions" within the
meaning of the same Section 1.1502-13 have been made on an arm's-length basis;
(vi) none of the Continuing Subsidiaries has an "excess loss account," as
defined in Section 1.1502-19 of the regulations under the Code, in the stock of
any other corporation; and (vii) for all open taxable years, the Company and
each Continuing Subsidiary and all Funds managed thereby are in compliance with
respect to all backup withholding and information reporting requirements in the
Code and the regulations thereunder, including, but not limited to all necessary
due diligence mailings and the proper and timely filing of Forms W-3, and such
Funds are similarly in compliance with all withholding and information reporting
requirements of any state, local or foreign jurisdiction to which any of them
may be subject, except in the case of clauses (iv) and (vii) for such instances
of non-compliance which,

                                      A-14
<PAGE>   98

individually or in the aggregate, would not reasonably be expected to have a
Company Material Adverse Effect.

     (f) Notwithstanding anything in this Section 3.13 to the contrary, the
Company shall not be deemed to have made any representation or warranty under
this Section 3.13 with respect to any liability, obligation, action or failure
to act for which the Company or a Continuing Subsidiary is indemnifiable under
the Distribution Agreement or the Tax Separation Agreement.

     3.14  Compliance with Laws; Permits.  Neither the Company nor any
Continuing Subsidiary (a) is in violation of, or has violated, any applicable
provisions of any laws, statutes, ordinances or regulations (including any rules
or regulations of any non-governmental self-regulatory organization or agency)
or (b) since January 1, 1998, has received any notice from any non-governmental
self-regulatory organization or agency, governmental body, agency, official or
authority or any other person that either the Company or any Continuing
Subsidiary is in violation of, or has violated, any applicable provisions of any
material laws, statutes, ordinances or regulations, except in the case of
clauses (a) and (b) for violations or alleged violations which, individually or
in the aggregate, would not reasonably be expected to have a Company Material
Adverse Effect. The Company and each of its Continuing Subsidiaries have all
permits, licenses and franchises from Governmental Entities required to conduct
their businesses as now being conducted, except for such permits, licenses and
franchises the absence of which would not reasonably be expected to have a
Company Material Adverse Effect.

     3.15  Intellectual Property.  The Company, or a Continuing Subsidiary, owns
or has all necessary rights to use each patent, patent application, trademark
(whether or not registered), trademark application, trade name, service mark,
copyright and other trade secret or proprietary intellectual property
(collectively, "Intellectual Property") used in and material to their respective
businesses, and none of the previous or current development, manufacture,
marketing or distribution of products or services of or by the Company or any
Continuing Subsidiary infringes the right of any other person, except for any
such infringements that would not, individually or in the aggregate, reasonably
be expected to have a Company Material Adverse Effect. Except as disclosed in
the Commission Filings filed prior to the date hereof, no other person is
infringing the rights of the Company or any Continuing Subsidiary in any such
Intellectual Property, except for any such infringements that would not,
individually or in the aggregate, reasonably be expected to have a Company
Material Adverse Effect.

     3.16  No Undisclosed Material Liabilities.  Except as disclosed in the
Commission Filings filed prior to the date hereof and except for liabilities not
required by generally accepted accounting principles to be recorded on a balance
sheet or liabilities arising since December 31, 1999 in the ordinary course of
business as of the date hereof, there are no liabilities of the Company or any
Continuing Subsidiary of any kind whatsoever, whether accrued, contingent,
absolute, determined, determinable or otherwise, that would, individually or in
the aggregate, reasonably be expected to have a Company Material Adverse Effect.

     3.17  Fairness Opinion, Brokers.

     (a) The Company has received the oral opinion of Merrill Lynch & Co., Inc.
and Salomon Smith Barney, Inc. (the "Financial Advisors") that, as of the date
that such opinion was given, the Cash Consideration is fair to the Stockholders
from a financial point of view.

     (b) Except for the Financial Advisors, no agent, broker, person or firm
acting on behalf of the Company is or will be entitled to any advisory
commission or broker's or finder's fee from any of the parties hereto in
connection with any of the transactions contemplated herein. Accurate and
complete copies of all agreements between or among the Company and the Financial
Advisors relating to such transactions have been provided to the Parent.

     3.18  Investment Advisory Activities.

     (a) Section 3.18(a) of the Disclosure Schedule contains a list, as of April
30, 2000, of (1) all of the investment companies registered under the Investment
Company Act (the "Funds") for which Pioneer

                                      A-15
<PAGE>   99

Investment Management, Inc. ("PIM") or any other Continuing Subsidiary acts as
investment adviser, (2) each pooled investment fund for which PIM or any other
Continuing Subsidiary acts as investment adviser and which is not required to
register under the Investment Company Act ("Non-Registered Funds") and (3) any
other investment advisory clients ("Non-Fund Clients") of PIM or any other
Continuing Subsidiary of the Company, showing the aggregate amount of assets
under management with the Company and its Continuing Subsidiaries as of such
date.

     (b) The Company has previously made available to the Parent copies of each
investment advisory agreement with any of the Funds, Non-Registered Funds or
Non-Fund Clients listed in Section 3.18(b) of the Disclosure Schedule (the
"Client Contracts").

     (c) Each Client Contract and any subsequent renewal has been duly
authorized, executed and delivered by the applicable Continuing Subsidiary or
the Company and is a valid and legally binding agreement, enforceable against
such Continuing Subsidiary or the Company and, to the knowledge of the Company,
each other party thereto, except (with respect to each such other party) as
enforceability may be limited by bankruptcy, insolvency, fraudulent transfer,
reorganization, moratorium or other similar laws relating to or affecting the
rights of creditors generally and by equitable principles, including those
limiting the availability of specific performance, injunctive relief and other
equitable remedies and those providing for equitable defenses.

     (d) None of the Continuing Subsidiaries is currently in default under any
of the terms of any Client Contract other than defaults which would not,
individually or in the aggregate, reasonably be expected to have a Company
Material Adverse Effect.

     (e) None of the Company, any of its Continuing Subsidiaries that are
registered under the Investment Advisers Act or any other person "associated"
(as defined under the Investment Advisers Act) with the Company or any of such
Continuing Subsidiaries is subject to disqualification pursuant to Section
203(e) of the Investment Advisers Act or to serve as an investment adviser or as
an associated person to a registered investment adviser, or subject to
disqualification pursuant to Rule 206(4) -- 3 under the Investment Advisers Act
or subject to disqualification to serve as a broker-dealer under Section 15 of
the Exchange Act or the subject of a rebuttable presumption pursuant to Rule
206(4)-4(b) under the Investment Advisers Act. None of the Company, any of its
Continuing Subsidiaries or any "affiliated person" (as defined under the
Investment Company Act) thereof is subject to disqualification as an investment
adviser or any other capacity contemplated by the Investment Company Act for any
investment company under Section 9(a) of the Investment Company Act.

     (f) PIM is registered as an investment adviser under the Investment
Advisers Act. Pioneer Funds Distributor, Inc. ("PFD") is registered as a
broker-dealer under the Exchange Act and is a member in good standing of the
NASD. Pioneering Services Corporation ("PSC") is registered as a transfer agent
under the Exchange Act. Pioneer Management (Ireland) Limited is registered as a
transfer agent under the Exchange Act.

     (g) PIM and each Fund have adopted a written code of ethics and a written
policy regarding personal trading. Such code and policy currently comply, and
have complied, in all material respects with Section 17(j) of the Investment
Company Act, Rule 17j-1 thereunder, and Section 204A of the Investment Advisers
Act, as the case may be. To the knowledge of the Company, there has been no
violation of PIM's code of ethics and personal trading policy that has not been
reported to the Board of Trustees of the Funds and would constitute a fraud upon
any of the Funds.

     3.19  Registered Investment Companies.

     (a) Each Fund is, and at all times required under the Investment Company
Act has been, duly registered with the Commission as an investment company under
the Investment Company Act and has been duly organized, and is validly existing
and in good standing under the laws of the jurisdiction of its

                                      A-16
<PAGE>   100

organization and has the requisite power and authority to carry on its business
as it is now being conducted.

     (b) The Company has made available to the Parent and the Purchaser copies
of the (i) audited financial statements for each of the Funds for each of their
respective fiscal years ended in 1999 (the "Fund Annual Financial Statements")
and (ii) any audited or unaudited semi-annual financial statements for a Fund
for its semi-annual period, if any, ended after the date of the Annual Financial
Statements and on or prior to February 29, 2000 (the "Fund Interim Financial
Statements" and, together with the Fund Annual Financial Statements, the "Fund
Financial Statements"). Each Fund Financial Statement has been prepared in
accordance with generally accepted accounting principles consistently applied by
the Fund on a consistent basis, except as may be indicated therein or in the
notes thereto, and fairly presents in all material respects the financial
position and statement of net assets as of the date thereof and the results of
operations for the period then ended, subject, in the case of the Fund Interim
Financial Statements, to normal year-end adjustments and to the absence of
complete notes. None of the Funds has incurred any obligation or liability
(contingent or other) that, individually or in the aggregate, is or when
accrued, would be, material to the financial condition or results of operations
of such Fund, except as reflected in its Fund Financial Statements or as may be
incurred in the ordinary course of its investment operations since the date of
the Fund Interim Financial Statements and which would not, individually or in
the aggregate, reasonably be expected to have a Fund Material Adverse Effect.
For purposes of this Agreement, "Fund Material Adverse Effect" shall mean any
change, effect or circumstance that is, or is reasonably likely to result in,
liability to the Company or any of its Continuing Subsidiaries that would have a
Company Material Adverse Effect or which would be materially adverse to the
business or operations of the Funds and Non-Registered Funds, taken as a whole,
other than changes that result from economic factors affecting the economy as a
whole or the industry or geographical region in which the Fund or Non-Registered
Fund invests, changes in the net assets of such Funds or Non-Registered Funds
due to redemptions, changes in the market value of portfolio securities or
changes that are the result of factors generally affecting the mutual fund
industry.

     (c) Each Client Contract with a Fund, the Administration Agreement among
the Funds and PIM (the "Administration Agreement"), each Underwriting Agreement
(the "Underwriting Agreement") between PFD and a Fund, and each agreement (the
"Services Agreement") between PSC and a Fund, and any subsequent renewal of any
such agreement, has been duly authorized, executed and delivered by PIM, PFD or
PSC, as the case may be, and the Fund and is a valid and legally binding
agreement, enforceable against PIM, PFD, PSC, as the case may be, and the Fund
and, if applicable, has been adopted in compliance with Section 12(b) or Section
15 of the Investment Company Act.

     (d) Each current prospectus (which term, as used in this Agreement, shall
include any related statement of additional information), as amended or
supplemented, relating to each Fund has been supplied or made available to the
Parent and the Purchaser. Each such prospectus, as amended or supplemented, is
in substantial compliance with the requirements of the Securities Act and the
Investment Company Act, and, where applicable, the rules of the NASD, except for
such non-compliance which would not, individually or in the aggregate,
reasonably be expected to have a Fund Material Adverse Effect. Each of the Funds
has filed all prospectuses, financial statements, other forms, reports, sales
literature, and advertising, and any other documents required to be filed with
applicable Governmental Entities, and any amendments thereto (the "Reports"),
the failure to file which would not, individually or in the aggregate, have a
Fund Material Adverse Effect. The Reports have been prepared in accordance with
the requirements of applicable law, except for such non-compliance which would
not, individually or in the aggregate, reasonably be expected to have a Fund
Material Adverse Effect.

     (e) Except as set forth in the Fund Financial Statements or current
prospectuses, none of the Client Contracts with a Fund, the Administration
Agreement, the Underwriting Agreements or the Services Agreements contains any
undertaking by PIM, PFD or PSC, as the case may be, to cap fees or to reimburse
any or all fees thereunder.

                                      A-17
<PAGE>   101

     (f) A copy of each distribution plan adopted by the Board of any Fund under
Rule 12b-1 under the Investment Company Act ("12b-1 Plan") (or form of 12b-1
Plan adopted by similar series or classes of shares offered by a Fund) has been
made available to Parent; and all payments due since December 31, 1998 and prior
to the most recently ended payment period under each distribution plan or
principal underwriting agreement to which any Fund is a party have been made in
compliance with the related 12b-1 Plan.

     (g) Each of the proxy solicitation materials to be distributed to the
shareholders of each Fund in connection with the approvals described in Section
4.3 will contain all information necessary in order to make the disclosure of
information therein satisfy the requirements of Section 14 of the Exchange Act,
Section 20 of the Investment Company Act and the rules and regulations
thereunder and such materials (except to the extent supplied by or related to
Parent or its affiliates) will be complete in all material respects and will not
contain (at the time such materials are distributed, filed or provided at the
time of the relevant vote of the shareholders of each Fund in connection with
the approvals described in Section 4.3) any untrue statement of a material fact
or omit to state any material fact necessary in order to make the statements
made therein, in the light of the circumstances under which they were made, not
misleading or necessary to correct any statement or any earlier communication
with respect to the solicitation of a proxy for the same meeting or subject
matter which has become false or misleading.

     (h) Neither the execution and delivery of this Agreement by the Company,
nor the consummation by the Company of the transactions contemplated hereby, nor
compliance by the Company with any of the provisions hereof will (i) (x)
violate, conflict with, or result in a breach of any provision of the charter,
by-laws or similar organizational documents of any of the Funds, or (y) violate,
conflict with, or result in a breach of any provision of, or constitute a
default (or an event that, with notice or lapse of time or both, would
constitute a default) under, or result in the termination of, or accelerate the
performance or payment required by, or result in a right of termination or
acceleration under, or result in the creation of any lien, security interest,
charge or encumbrance upon any of the properties or assets of any of the Funds,
under any of the terms, conditions or provisions of any note, bond, mortgage,
indenture, deed of trust, license, lease, distribution agreement, or joint
venture agreement to which any of the Funds is a party or to which any of them
or any of their respective properties or assets may be subject or (ii) violate
any judgment, ruling, order, writ, injunction, decree, statute, rule or
regulation applicable to any of the Funds or any of their respective properties
or assets; except, in the case of each of clauses (i)(y) and (ii) above, for
such violations, conflicts, breaches, defaults, terminations, accelerations or
creations of liens, security interests, charges or encumbrances that,
individually or in the aggregate, would not reasonably be expected to have a
Fund Material Adverse Effect.

     (i) Each of the Funds is governed by a board of trustees consisting of at
least 50% of trustees who are not "interested persons" (as defined in the
Investment Company Act) of such Fund.

     (j) None of the Funds (a) is in violation of, or since January 1, 1998 has
violated, any applicable provisions of any laws, statutes, ordinances or
regulations (including any rules or regulations of any non-governmental
self-regulatory organization or agency) or (b) has received any notice from any
non-governmental self-regulatory organization or agency, governmental body,
agency, official or authority or any other person that any Fund is in violation
of, or has violated, any applicable provisions of any laws, statutes, ordinances
or regulations, except in the case of clauses (a) and (b) for violations or
alleged violations which, individually or in the aggregate, would not reasonably
be expected to have a Fund Material Adverse Effect. Without limiting the
generality of the foregoing, none of the Funds has been enjoined, indicted,
convicted or made the subject of disciplinary proceedings, consent decrees or
administrative orders on account of any violation of the Securities Act, the
Exchange Act, the Investment Company Act or any similar law of a non-U.S.
jurisdiction. The Funds have all permits, licenses and franchises from
Governmental Entities required to conduct their businesses as now being
conducted, except for such permits, licenses and franchises the absence of which
would not, individually or in the aggregate, reasonably be expected to have a
Fund Material Adverse Effect.

                                      A-18

     (k) Each Fund has elected to qualify and, for all taxable years that a
Continuing Subsidiary served as investment adviser and with respect to which the
applicable statute of limitations (including any extensions) has not expired
("open taxable years"), has continuously qualified to be treated as a "regulated
investment company" under Subchapter M of the Code and has continuously been
eligible to compute, and has for each such taxable year computed, its federal
income tax under Section 852 of the Code and has no earnings and profits
accumulated in any taxable year that is not an open taxable year. At the
Effective Time, all federal, state, local and foreign tax returns with respect
to taxes for any taxable period for which the applicable statute of limitations
(including any extensions) has not expired and during which a Continuing
Subsidiary has served as investment adviser that were or are required to be
filed on or before such date by or on behalf of a Fund ("Fund Tax Returns') were
or shall have been timely filed and were or shall be complete and correct in all
material respects and all federal and other taxes, including interest,
penalties, and additions to tax, shown or required to be shown as due on such
returns, shall have been paid or provided for. No such Fund Tax Return or other
filing is currently under audit, no assessment has been asserted with respect to
such Fund Tax Returns or other filings, and no requests for waivers of the time
to make any such assessment are pending. None of the Funds is delinquent in the
payment of any material tax, assessment, or governmental charge.

     (l) There are no actions, suits, proceedings or investigations pending or
to the best knowledge of the Company, threatened against any of the Funds, nor
is any Fund subject to any order, judgment, writ, injunction or decree naming
such Fund, except in either case for matters that, individually or in the
aggregate, would not reasonably be expected to have a Fund Material Adverse
Effect.

     (m) The books and records of each Fund reflecting, among other things, the
investment transactions undertaken on behalf of each Fund, the purchase and sale
of shares of that Fund by its holders of shares of beneficial interests
(collectively, "Fund Stockholders"), the number of issued and outstanding Fund
shares owned by each Fund Stockholder, and the state or other jurisdiction in
which those Fund shares were offered and sold, are, to the knowledge of the
Company, complete and accurate in all respects, except for such omissions or
errors which, individually or in the aggregate, would not reasonably be expected
to have a Fund Material Adverse Effect.

     (n) Each Fund has in full force and effect such insurance as is required by
the Investment Company Act and has directors' and officers' and errors and
omissions insurance policies. Copies of all insurance policies of the Funds have
been made available to Parent. All premiums that are due and payable under such
policies have been paid.

     (o) Since December 31, 1999, there has not been any event, change or effect
which, individually or in the aggregate, has resulted in a Fund Material Adverse
Effect.

     3.20  Non-Registered Funds.

     (a) Each Non-Registered Fund has been duly organized, and is validly
existing and in good standing under the laws of the jurisdiction of its
organization and has the requisite power and authority to carry on its business
as it is now being conducted.

     (b) The Company has made available to Parent copies of the audited
financial statements for each of the Non-Registered Funds for each of their
respective fiscal years ending in 1999 (the "Non-Registered Fund Annual
Financial Statements") and, to the extent that the Company or any Continuing
Subsidiary is contractually obligated to produce such financial statements, the
unaudited financial statements for each of the Non-Registered Funds for each of
their respective fiscal periods ended after the date of the Non-Registered Funds
Annual Financial Statements and on or before February 29, 2000 (the
"Non-Registered Fund Interim Financial Statements" and, together with the
Non-Registered Fund Annual Financial Statements, the "Non-Registered Fund
Financial Statements"). Each Non-Registered Fund Financial Statement has been
prepared in accordance with such accounting principles as the Non-Registered
Fund purports to comply in any report provided to the holders of the shares or
other equity interests in the Non-Registered Funds. None of the Non-Registered
Funds has incurred any obligation or liability (contingent

                                      A-19
<PAGE>   103

or other) that, individually or in the aggregate, is or when accrued, would be,
material to the financial condition or results of operations of such
Non-Registered Fund, except (i) as reflected in its Non-Registered Fund
Financial Statements, (ii) as may be incurred in the ordinary course of its
investment operations since the date of the Non-Registered Fund Financial
Statements, or (iii) which would not, individually or in the aggregate,
reasonably be expected to have a Fund Material Adverse Effect.

     (c) There are no actions, suits, proceedings or investigations pending or,
to the best knowledge of the Company, threatened against any of the
Non-Registered Funds, nor is any Non-Registered Fund subject to any order,
judgment, writ, injunction or decree naming such Non-Registered Fund, except in
either case for matters that, individually or in the aggregate, would not
reasonably be expected to have a Fund Material Adverse Effect.

     (d) None of the Non-Registered Funds (a) is in violation of, or has since
January 1, 1998 violated, any applicable provisions of any laws, statutes,
ordinances or regulations (including any rules or regulations of any
non-governmental self-regulatory organization or agency) or (b) has received any
notice from any non-governmental self-regulatory organization or agency,
governmental body, agency, official or authority or any other person that any
Non-Registered Fund is in violation of, or has violated, any applicable
provisions of any laws, statutes, ordinances or regulations, except in the case
of clauses (a) and (b) for violations or alleged violations which, individually
or in the aggregate, would not reasonably be expected to have a Fund Material
Adverse Effect. Without limiting the generality of the foregoing, none of the
Non-Registered Funds has been enjoined, indicted, convicted or made the subject
of disciplinary proceedings, consent decrees or administrative orders on account
of any violation of the Securities Act, the Exchange Act, the Investment Company
Act or any similar law of a non-U.S. jurisdiction. The Non-Registered Funds have
all permits, licenses and franchises from Governmental Entities required to
conduct their businesses as now being conducted, except for such permits,
licenses and franchises the absence of which would not, individually or in the
aggregate, reasonably be expected to have a Fund Material Adverse Effect.

     3.21  Material Contracts.  Except as disclosed in the Commission Filings
filed prior to the date hereof, as of the date hereof, neither the Company nor
any of its Continuing Subsidiaries is a party to or bound by any written or oral
contract:

     (a) with respect to the employment of any directors or officers, other than
noncompetition and confidentiality agreements with such persons and other than
contracts terminable by the Company upon no more than 60 days' notice without
penalty;

     (b) that is a "material contract" of the Company (as is defined in Item
601(b)(10) of Regulation S-K of the Commission) to be performed after the date
of this Agreement;

     (c) that, after the Effective Time, will materially restrict the conduct of
any line of business by the Company or its Continuing Subsidiaries or upon
consummation of the Merger will materially restrict the ability of the Surviving
Corporation to engage in any line of business in which it may lawfully engage;

     (d) with a labor union (including any collective bargaining agreement); or

     (e) any of the benefits of which will be increased, or the vesting of the
benefits of which will be accelerated, by the occurrence of any Stockholder
approval or the consummation of any of the transactions contemplated by this
Agreement, or the value of any of the benefits of which will be calculated on
the basis of any of the transactions contemplated by this Agreement.

     All of the foregoing, together with the Client Contracts, Administration
Agreement, Underwriting Agreements and Service Agreements, are collectively
called "Material Contracts." To the extent Material Contracts are evidenced by
documents, copies thereof have been delivered or made available to Parent.
Section 3.23 of the Disclosure Schedule sets forth a description of the material
terms of each Material Contract that has not been reduced to writing. Each
Material Contract is in full force and effect and is enforceable against the
Company or the applicable Continuing Subsidiary, as the case may be, in

                                      A-20
<PAGE>   104

accordance with its terms, except where the failure to be in full force and
effect would not, individually or in the aggregate, reasonably be expected to
have a Company Material Adverse Effect. There does not exist under any Material
Contract any material default or condition or event that, after notice or lapse
of time or both, would constitute a default on the part of the Company or its
Continuing Subsidiary or, to the knowledge of the Company, on the part of any
other parties to such Material Contracts except for such defaults which,
individually or in the aggregate, would not reasonably be expected to have a
Company Material Adverse Effect.

     3.22  Insurance.  The Company and its Continuing Subsidiaries maintain
policies of insurance on terms, and in amounts, that have previously been
disclosed to the Parent.

     3.23  State Takeover Statutes.  The Board of Directors of the Company has
taken all action necessary to ensure that the restrictions on business
combinations contained in Section 203 of Delaware Law will not apply to the
Merger and the other transactions contemplated by this Agreement. To the
knowledge of the Company, no other state takeover statute is applicable to the
Merger or the other transactions contemplated by this Agreement.

     3.24  Vote Required.  The affirmative vote of the holders of a majority of
the Shares is the only vote of the holders of any class or series of capital
stock of the Company necessary to approve this Agreement and the Merger.

     3.25  Harbor Global.

     (a) As of the Effective Time, shares of equity, intercompany obligations or
similar equity or debt interests in the entities to be transferred to Harbor
Global pursuant to the Distribution Agreement (the "Harbor Global Entities") and
cash in an amount not to exceed $25 million (or such lesser number that is equal
to $25 million minus the aggregate amount of the Company's obligations (but not
obligations in connection with Options or restricted stock) to employees of
Harbor Global under severance or termination agreements between such employees
and the Company to the extent such obligations are not assumed by Harbor Global
with the consent of such employees) will be the only assets that are owned,
leased or licensed by Harbor Global which were previously owned, leased or
licensed by the Company or any Continuing Subsidiary.

     (b) Except as disclosed in Section 3.25(b) of the Disclosure Schedule or as
set forth in Schedule 4.2(a) of the Distribution Agreement and except for such
other liabilities as shall not exceed $35 million, Harbor Global has no
liabilities of any kind whether accrued, contingent, absolute, determined,
determinable or otherwise.

     (c) Except as disclosed in Section 3.25(c) of the Disclosure Schedule and
except for liabilities (but not in an amount in excess of $7.5 million) with
respect to which the Company is indemnifiable by Harbor Global pursuant to the
Distribution Agreement or has obtained a release therefrom, none of the Company
or any of its Continuing Subsidiaries is liable (whether on a contingent,
determinable or other basis) for any liabilities of any kind (whether accrued,
contingent, absolute, determined, determinable or otherwise) of the Harbor
Global Entities, including, without limitation, pursuant to any indemnification
arrangement, capital commitment or guarantee.

     (d) Section 3.25(d) of the Disclosure Schedule sets forth a list of all
agreements or arrangements between or among the Company or any of its Continuing
Subsidiaries, on the one hand, and any Harbor Global Entity, on the other hand,
or to which the Company or any of its Continuing Subsidiaries, on the one hand,
and any Harbor Global Entity, on the other hand, are parties. The Parent agrees
that the Company shall be entitled, from time to time, to supplement Section
3.25(d) of the Disclosure Schedule to provide for intercompany services and
subleases. If the Parent shall reasonably object to any such addition to Section
3.25(d) of the Disclosure Schedule, the Company shall use commercially
reasonable efforts to implement alternatives not involving the Company or any
Continuing Subsidiary as promptly as reasonably practicable and if such
alternative cannot be implemented, the Company shall not implement

                                      A-21
<PAGE>   105

the proposed arrangement with Harbor Global without the Parent's consent, which
consent shall not unreasonably be withheld, conditioned or delayed.

     3.26  Bank of Italy Requirements.  As of the Effective Time, the Company
and its Continuing Subsidiaries have or will implement prior to the Effective
Time the systems necessary to comply with the requirements of the Bank of Italy
regarding the activities of the Italian banking groups, a summary of which has
previously been provided by the Parent to the Company.

     3.27  Company's Knowledge.  For purposes of this Agreement and all
certificates and other documents delivered in connection herewith, the term
"Company's knowledge" or "Company's best knowledge" or similar phrases shall
mean the knowledge of the Chief Executive Officer, President, Chief Financial
Officer and General Counsel of the Company, PIM, PFD or PSC, which shall be
deemed to include the knowledge that such person would have had if he or she had
made reasonable inquiry.

     3.28  Schedules and Exhibits.  Disclosure of any fact or item in the
Disclosure Schedule (or any update thereto) shall be deemed to modify (a) only
the corresponding section of this Agreement and (b) other sections of this
Agreement to the extent it is reasonably clear (notwithstanding the absence of a
specific cross reference) from a reading of the disclosure that the disclosure
is applicable to such other sections.

     3.29  No Implied Representation.  Notwithstanding anything contained in
this Article 3 or any other provision of this Agreement, it is the explicit
intent of the Parent and the Purchaser that the Company is making no
representation or warranty whatsoever, express or implied, beyond those
expressly given in this Agreement, including, but not limited to, any implied
warranty or representation as to condition, merchantability, suitability or
fitness for a particular purpose as to any of the properties or assets of the
business conducted by the Company and the Subsidiaries and, except as expressly
represented in this Agreement, it is understood that the Parent and the
Purchaser take such business, properties and assets on an "as is" and "where is"
basis. It is understood that any cost estimates, projections, or other
predictions contained or referred to in the Confidential Descriptive Memorandum,
dated March 2000, distributed by the Financial Advisors, or, unless expressly
provided otherwise in this Agreement, otherwise provided by the Company or the
Financial Advisors, are not and shall not be deemed to be representations or
warranties of the Company.

Subsidiaries and to preserve for the Parent and the Surviving Corporation the
present relationships and good will of the Company and its Continuing

connection with this Agreement, concerning (or concerning the business of the
Company or any Continuing Subsidiary in connection with) any tender offer for

proposed tender offer, exchange offer, merger, consolidation, sale of material
assets, recapitalization, accumulation of Shares or proxy solicitation or other
business combination being referred to herein as "Acquisition Proposals").
Notwithstanding the foregoing, the Company, its Continuing Subsidiaries, and
their respective officers, directors, employees, representatives and agents (i)
may, in the case of a Qualified Acquisition Proposal (as hereinafter defined),
furnish or cause to be furnished information concerning the Company's and its
Continuing Subsidiaries' businesses, properties or assets to a Third Party
(subject to such Third Party executing a confidentiality agreement on terms no
less favorable to the Company than those in the Confidentiality Agreement
between the Parent and the Company dated March 23, 2000), (ii) may, in the case
of a Qualified Acquisition Proposal only, enter into, participate in, conduct or
engage in discussions or negotiations with such Third Party, (iii) may take any
position with respect to an Acquisition Proposal in accordance with Rules 14a-9
and 14e-2 promulgated under the Exchange Act, and (iv) may, in the case of a
Qualified

                                      A-26

Acquisition Proposal and in compliance with the provisions of clause (c) of this
Section 5.5, enter into an agreement to consummate a Qualified Acquisition
Proposal. As used herein, "Qualified Acquisition Proposal" means a bona fide,
written Acquisition Proposal at a price per Share that the Company's Board of
Directors (after consultation with a financial advisor of nationally recognized
reputation) believes in good faith to be superior to the Cash Consideration and
in the best interests of the Stockholders.

     (b) The Company will promptly notify the Parent of, and will disclose to
the Parent all material details of any Acquisition Proposal it receives
(including, without limitation, the identity of the Third Party making such
Acquisition Proposal). In the event that the Company furnishes any nonpublic
information to any party other than the Parent, it shall simultaneously provide
the Parent with copies of or access to all such information. Nothing in this
paragraph (b) shall be construed as interfering with the Company's obligations
to its Stockholders under Rule 14e-2 promulgated under the Exchange Act.

     (c) Except as expressly permitted by this Section 5.5(c), neither the
Company's Board of Directors nor any committee thereof shall or shall resolve to
(i) not recommend or withdraw its approval or recommendation of the Merger, this
Agreement or any of the transactions contemplated hereby, (ii) modify or qualify
such approval or recommendation in a manner adverse to the Parent or the
Purchaser, (iii) approve or recommend any proposed Acquisition Proposal or (iv)
cause the Company to enter into any letter of intent, agreement in principle,
acquisition agreement or other similar agreement relating to an Acquisition
Proposal (or publicly propose to do any of the foregoing). Notwithstanding the
foregoing, in the event that prior to the Company Stockholders' Meeting the
Company's Board of Directors determines in good faith, after it has received a
Qualified Acquisition Proposal and after consultation with outside counsel, that
it must take such action to comply with its fiduciary duties to the Stockholders
under applicable law, then the Company's Board of Directors may (subject to this
sentence) take any of the actions contemplated by clauses (i), (ii), (iii) and
(iv) of the preceding sentence (a "Subsequent Action"), but only (i) at a time
that is after the fifth business day following delivery by the Company to the
Parent of a written notice advising the Parent that the Company's Board of
Directors has received a Qualified Acquisition Proposal specifying the material
terms and conditions of such Qualified Acquisition Proposal, identifying the
person making such Qualified Acquisition Proposal stating that it intends to
make or take a Subsequent Action; (ii) if the Parent does not, within such five
business days following delivery of such notice, offer to make such adjustments
in the terms and conditions of this Agreement such that the Company's Board of
Directors by majority vote determines in its good faith judgment (after
consultation with a financial advisor of nationally recognized reputation) to be
as favorable to the Stockholders as such Qualified Acquisition Proposal; and
(iii) if the Company has complied with this Section 5.5.

     (d) The Company shall immediately cease and cause to be terminated any
activities, discussions, or negotiations, existing on the date hereof, with any
person with respect to any Acquisition Proposal, and will promptly request that
each such person return or destroy all confidential information previously
produced to that person by the Company or its Subsidiaries.

     5.6  Notification of Certain Matters.  The Company shall give prompt notice
to the Parent, of (i) the obtaining by it of actual knowledge as to the matters
set forth in clauses (x) and (y) of clause (ii) of this sentence, or (ii) the
occurrence, or failure to occur, of any event which occurrence or failure to
occur causes (x) any representation or warranty made by the Company and
contained in this Agreement to be untrue or inaccurate in any material respect
at any time from the date hereof to the Effective Time, or (y) any material
failure of the Company or of any officer, director, employee or agent thereof,
to comply with or satisfy any covenant, condition or agreement to be complied
with or satisfied by it under this Agreement; provided, however, that no such
notification shall be deemed to cure any breach or otherwise affect the
representations or warranties of the Company or the conditions to the
obligations of the parties hereunder. The Parent shall give prompt notice to the
Company of (i) the obtaining by it of actual knowledge as to the matters set
forth in clauses (x) and (y) of clause (ii) of this sentence, or (ii) the
occurrence, or failure to occur, of any event which occurrence or failure to
occur causes (x) any representation or warranty made by the Parent or the
Purchaser contained in this Agreement to be untrue

                                      A-27
<PAGE>   111

or inaccurate in any material respect at any time from the date hereof to the
Effective Time, or (y) any material failure of the Parent or the Purchaser, or
of any officer, director, employee or agent thereof, to comply with or satisfy
any covenant, condition or agreement to be complied with or satisfied by it
under this Agreement; provided, however, that no such notification shall be
deemed to cure any breach or otherwise affect the representations or warranties
of the Parent or the Purchaser or the conditions to the obligations of the
parties hereunder.

     5.7  Access to Information.  Except as prohibited by confidentiality
agreements to which the Company is a party or as restricted under applicable
law, the Company shall, and shall cause its Continuing Subsidiaries, and the
Company's and such Continuing Subsidiaries' respective officers, directors,
employees and agents to, afford to the Parent and to the officers, employees and
agents of the Parent complete access at all reasonable times, from the date
hereof to the Effective Time, to the Company's and any Continuing Subsidiary's
officers, employees, agents, properties, books, records and contracts, and shall
furnish the Parent all financial, operating and other data and information as
the Parent, through its officers, employees or agents, may reasonably request.

     5.8  Indemnification and Insurance.  The Parent and the Purchaser agree
that all rights to indemnification, advancement of expenses, exculpation,
limitation of liability and any and all similar rights now existing in favor of
the employees, agents, directors or officers of the Company and its Continuing
Subsidiaries (the "Indemnified Parties") as provided in their respective
charters or by-laws in effect on the date hereof (copies of which have been
provided to the Parent), shall survive the Merger and shall continue in full
force and effect for a period of six years from the Effective Time; provided,
however, that in the event any claim or claims are asserted or made within such
six-year period, all rights to indemnification in respect to any such claim or
claims shall continue until the disposition of any and all such claims. The
Parent agrees to provide each individual who served as a director or officer of
the Company or its Continuing Subsidiaries at any time prior to the Effective
Time with liability insurance for a period of six years after the Effective Time
no less favorable in coverage and amount than any applicable insurance in effect
immediately prior to the Effective Time; provided, however, that the Parent may
reduce the coverage and amount of liability insurance to the extent that the
cost thereof would exceed 200% of the cost of any such insurance in effect
immediately prior to the Effective Time. The Indemnified Parties shall be deemed
third party beneficiaries of this provision and shall be entitled to bring
actions to enforce the obligations of the Parent and the Purchaser under this
Section 5.8.

     5.9  Fair Price Structure.  If any "fair price" or "control share
acquisition" or "anti-takeover" statute, or other similar statute or regulation
or any state "blue sky" statute shall become applicable to the transactions
contemplated hereby, the Company and the Company's Directors shall grant such
approvals and take such actions as are reasonably necessary so that the
transactions contemplated hereby and thereby may be consummated as promptly as
practicable on the terms contemplated hereby and thereby, and otherwise act to
minimize the effects of such statute or regulation on the transactions
contemplated hereby or thereby.

     5.10  Certain Post-Closing Fund Matters.  The Parent and Purchaser
acknowledge that the sale of the Shares is intended to qualify for the treatment
described in Section 15(f) of the Investment Company Act. In this regard, the
Parent and Purchaser shall, and from and after the Effective Time shall cause
the Company and each of its Continuing Subsidiaries to, (i) use all reasonable
efforts to assure that, for a period of three years after the Effective Time, at
least 75% of the Board of Directors or Trustees of each Fund or any permitted
successor thereto are not "interested persons" of the Company, the Parent or the
Purchaser, as that term is defined under applicable provisions of the Investment
Company Act and interpreted by the Commission; such efforts to include causing
any employee, officer, director or agent of the Company, the Parent or any
affiliate of the Parent who shall be a director or trustee of any fund to resign
when otherwise required to maintain such percentage, (ii) refrain from imposing
or seeking to impose, for a period of two years after the Effective Time, any
"unfair burden" on any Fund, within the meaning of the Investment Company Act,
and (iii) to use all reasonable efforts to ensure that all vacancies in the
Board of Directors or Trustees of any Fund shall be filled by a person who is
not a

                                      A-28
<PAGE>   112

"interested person" of the Parent or the Company and who has been selected and
proposed for election by a majority of the Directors or Trustees who are not
such interested persons.

     5.11  Severance Agreements.  Simultaneously with the Merger, the Parent
shall assume and agree to perform the Company's obligations under the severance
benefit agreements (complete and accurate copies of which have been provided to
the Parent) listed in the Disclosure Schedule.

     5.12  Parent Guaranty.  The Parent hereby unconditionally guarantees the
Purchaser's obligations under this Agreement and, if the Merger is consummated,
the indemnification obligations set forth in Section 5.8, and agrees to be
liable for any breach of this Agreement by the Purchaser (or a breach of Section
5.8).

     5.13  Continuation of Employment.  The Parent shall give (or cause to be
given) credit for past service for all purposes to the employees of the Company
and its Continuing Subsidiaries (the "Business Employees"). Starting at the
Effective Time, the Parent shall, for a period ending on the date twelve (12)
months after the Effective Time, provide (or cause to be provided) to each
Business Employee who continues his or her employment after the Effective Time
with total cash compensation (including base salary and bonus opportunity at
least equal to those in effect on the date hereof) that is no less favorable in
the aggregate to such employee's total cash compensation immediately prior to
the Effective Time. Starting at the Effective Time, the Parent shall also, for a
period ending on the date twelve (12) months after the Effective Time, maintain
(or cause to be maintained) employee benefit plans, agreements, programs,
policies and arrangements for the benefit of each such Business Employee that
are no less favorable in the aggregate than the employee benefit plans in effect
with respect to such Employees immediately prior to the Effective Time, other
than employee benefit plans, agreements, programs, policies and arrangements
providing for stock options, stock purchase rights, restricted stock or other
employer stock-based compensation and other than any employer stock provisions
of any qualified retirement plan maintained by the Company or any of its
Continuing Subsidiaries. Nothing in this Section 5.13 shall prevent the Parent,
the Surviving Corporation or its Continuing Subsidiaries from terminating the
employment of any of the Business Employees at any time after the Effective
Time. The Business Employees shall be deemed to be third party beneficiaries of
this provision and shall be entitled to bring action to enforce the obligations
of the Parent and the Purchaser under this Section 5.13.

     5.14  Incorporation of the Purchaser.  The Parent shall incorporate the
Purchaser as a Delaware corporation promptly after the date hereof and cause the
Purchaser to make the representations, warranties, covenants and agreements and
to assume the obligations hereunder of the Purchaser; provided, however, that if
the Parent is prohibited under Applicable Laws from incorporating the Purchaser
prior to the Effective Time, then either (i) the Parent may designate in writing
to the Company an existing direct or indirect wholly-owned subsidiary of the
Parent to be the Purchaser and shall cause such subsidiary to make the
representations, warranties, covenants and agreements and to assume the
obligations hereunder of the Purchaser or (ii) the Parent shall be deemed to
have agreed to have made the representations, warranties, covenants and
agreements and to have assumed the obligations hereunder of the Purchaser.

seeking any of the foregoing be pending before) a court of competent
jurisdiction or by a governmental, regulatory or administrative agency or

enacted by any governmental authority shall be in effect, which would make the
acquisition or holding by the Parent or its subsidiaries of the Shares or shares
of common stock of the Surviving Corporation illegal or otherwise prevent the
consummation of the Merger; provided, that the party seeking to assert this
condition shall have complied with its obligations under Section 5.4 of this
Agreement;

     (e) this Agreement and the Merger shall have been approved by the Bank of

permitted by the terms of this Agreement, (y) that the accuracy of
representations and warranties that by their terms speak as of the date of this
Agreement or some other date will be determined as of such date and (z) where

all respects would not, individually or in the aggregate, reasonably be expected
to have material adverse effect on the Parent or the Purchaser;

the terms of this Agreement, (Y) that the accuracy of representations and
warranties that by their terms speak as of the date of this Agreement or some
other date will be determined as of such date and (Z) only in the case of clause
(i), where any such failure of such representations and warranties to be true
and correct in all respects would not, individually or in the aggregate,
reasonably be expected to have a Company Material Adverse Effect; provided,
however, that this clause (Z) shall not be applicable if the Parent shall prove,
by clear and convincing evidence, that the failure of such representations and
warranties to be true and correct in all material respects resulted directly
from the intentional fraudulent conduct of the persons to whom the knowledge of
the Company is imputed under this Agreement;

     (b) The Company shall have performed in all material respects all
obligations and complied in all material respects with all covenants required by
this Agreement to be performed or complied with by it prior to the Effective

each of the Purchaser and the Company; or

     (b) by either the Parent or the Company if (i) the Effective Time shall not
have occurred on or before February 15, 2001; provided, however, that the right
to terminate this Agreement under this Section 7.1(b) shall not be available to

<PAGE>   115

commenced, and the Board of Directors of the Company fails to recommend against
acceptance of such tender offer or exchange offer by its Stockholders (including
by taking no position with respect to the acceptance of such tender offer or
exchange offer by its Stockholders);

     (d) by either the Parent or the Company if this Agreement shall fail to

Stockholders' Meeting (or an adjournment thereof);

     (e) by the Parent upon a breach of any representation or warranty or
material covenant or agreement on the part of the Company set forth in this
Agreement, or if any representation or warranty of the Company shall have become
untrue, in either case such that the conditions set forth in Section 6.3(a) and
Section 6.3(b) would not be satisfied ("Terminating Company Breach"); provided,
however, that, if such Terminating Company Breach is curable by the Company
through the exercise of its commercially reasonable efforts and for so long as
the Company continues to exercise such commercially reasonable efforts, the
Parent may not terminate this Agreement under this Section 7.1(e); or

     (f) by the Company upon a breach of any representation or warranty or

hereunder; provided that the foregoing shall not relieve any party for liability
for damages actually incurred as a result of any breach of this Agreement.
Notwithstanding any other provision contained in this Agreement to the contrary,
the Confidentiality Agreement shall survive the termination of this Agreement
for any reason.

     7.3  Amendment.  This Agreement may not be amended except by action of each
of the parties hereto set forth in an instrument in writing signed on behalf of
each of the parties hereto; provided, however, that if this Agreement and the
Merger are subject to Stockholder approval then, after approval of the Merger by
the Stockholders, no amendment may be made without the further approval of the
Stockholders which would do any of the following: (i) reduce the Cash
Consideration or change the form thereof; or (ii) change any other terms and
conditions of this Agreement if any of the changes, alone or in the aggregate,
would materially adversely affect the Stockholders (other than the Parent and
its affiliates).

                                      A-32
<PAGE>   116

     (b) If this Agreement is terminated by (i) the Parent pursuant to Section
7.1(c) or (ii) either the Company or the Purchaser pursuant to Section 7.1(d)
and the Company enters into, prior to the first anniversary of such date of
termination, a definitive agreement with respect to the sale of the Company and
such sale is consummated prior to the 18-month anniversary of such date of
termination (a "Subsequent Sale"), then, in the case of clause (i) or (ii), the
Company shall pay the Parent promptly (but in no event later than three business
days after the termination of this Agreement in the case of clause (i) the
Subsequent Sale in the case of clause (ii)) a fee of $37.5 million (the "Fee"),
which amount shall be payable in immediately available funds. In addition, upon

New York, as such bank's base rate.

     (d) This Section 7.5 shall survive any termination of this Agreement.

     8.1  Formation of Harbor Global.  As promptly as practicable after the date

Act or any applicable law, and the Company and the Parent will use commercially

of this Agreement, the Company shall not be deemed to be an affiliate or
subsidiary of the Purchaser or the Parent. The headings contained in this
Agreement are for reference purposes only and shall not affect in any way the
meaning or interpretation of this Agreement. Inclusion of information in the

                           HARBOR GLOBAL COMPANY LTD.
                                 COMMON SHARES

     This information statement is being furnished to stockholders of The

Group of common shares of its wholly owned subsidiary, Harbor Global Company
Ltd., to its stockholders. At the time of the distribution, you will be entitled
to receive one Harbor Global common share for every five shares of Pioneer Group
common stock held by you at that time. Following the distribution, all of the
outstanding Harbor Global common shares will be held pro rata by the
stockholders of Pioneer Group.

     Pioneer Group will distribute the shares of Harbor Global in connection
with the acquisition of Pioneer Group by UniCredito Italiano S.p.A., a
corporation organized under the laws of the Republic of Italy. The acquisition
of Pioneer Group will be effected by a merger of a wholly owned subsidiary of
UniCredito Italiano with and into Pioneer Group. Pioneer Group will survive the
merger as a wholly owned subsidiary of UniCredito Italiano.

     As a condition to closing the merger, Pioneer Group will transfer some of
its businesses and assets to Harbor Global and, before closing the merger,
distribute Harbor Global common shares to Pioneer Group stockholders of record.
At the time of the distribution, the Harbor Global assets will consist primarily
of the following businesses and assets currently owned or operated by Pioneer
Group:

     - real estate management and investment management operations in Russia;

     - Polish and Eastern European venture capital investment and management
       operations;

     - Polish and Eastern European real estate management operations;

     - gold exploration operations in Russia;

     - the proceeds from the sale of Pioneer Group's gold mining operations in
       Ghana; and

     - $25 million in cash.

Harbor Global will seek to liquidate its assets in a timely fashion on
economically advantageous terms.

     You will not pay for the Harbor Global common shares you will receive in
the distribution, but the distribution will be taxable to you. The Harbor Global
common shares are registered with the Securities and Exchange Commission on a
registration statement on Form 10 under the Securities Exchange Act of 1934,
effective as of [            ], 2000, and are transferable. However, there is no
current public trading market for Harbor Global common shares, and Harbor Global
common shares will not be listed on a securities exchange or on The Nasdaq Stock
Market(R). Furthermore, Harbor Global does not intend to take any action to
facilitate the development of an active trading market.

     The distribution record date will be the closing date of the merger. Harbor
Global expects the distribution to occur immediately prior to the closing of the
merger. The distribution is conditioned on the satisfaction or waiver of all
conditions to the obligations of Pioneer Group to consummate the merger provided

       and

     - after satisfying its liabilities, distribute any remaining proceeds to
       its shareholders.

     Harbor Global's memorandum of association provides that the liquidation of
its assets must be completed no later than the earlier of the fifth anniversary
of the distribution by Pioneer Group of Harbor Global common shares to its
shareholders or the distribution by Harbor Global of its assets to its
shareholders. If Harbor Global has not liquidated all of its assets before the
fifth anniversary of the distribution date, the Harbor Global board of directors
may authorize the company to continue to operate its assets for up to three
additional one year periods.

     At the time of the distribution, Harbor Global's assets will consist
primarily of the following businesses and assets, each of which is currently
owned or operated by Pioneer Group:

     - real estate management and investment management operations in Russia;

     - Polish and Eastern European venture capital investment and management
       operations;

     - Polish and Eastern European real estate management operations;

     - timber harvesting and sales in Russia;

     - gold exploration operations in Russia;

     - the proceeds from the sale of Pioneer Group's gold mining operations in
       Ghana; and

     - $25 million in cash.

Executive Officer, and Donald H. Hunter will be the Chief Operating Officer and

Calypso Management will manage the liquidation of Harbor Global and operate its
assets as going concern businesses pending their liquidation. Mr. Kasnet is the

                                THE TRANSACTIONS

     The Merger.  Harbor Global is currently a wholly owned subsidiary of
Pioneer Group. On May 14, 2000, Pioneer Group entered into a merger agreement
with UniCredito Italiano under which a wholly owned subsidiary of UniCredito
Italiano will merge with and into Pioneer Group. Pioneer Group will survive the
merger as a wholly owned subsidiary of UniCredito Italiano. As a condition to
closing the merger, Pioneer Group has agreed to transfer some of its business
and assets to Harbor Global and distribute Harbor Global common shares to
Pioneer Group stockholders immediately prior to closing the merger.

     For more information about the merger, the merger agreement and related
matters, you should refer to the merger proxy statement to which this
information statement is attached as Annex B. The merger agreement is attached
as Annex A to the merger proxy statement.

     The Distribution.  Immediately prior to closing the merger, Pioneer Group
will distribute Harbor Global common shares pro rata to its stockholders.
Following the distribution, all of the outstanding Harbor Global common shares
will be held by the stockholders of Pioneer Group. You will not pay for the
Harbor Global common shares you will receive in the distribution, but the
distribution will be taxable to you. The distribution is summarized below.

Distributing Corporation......   The Pioneer Group, Inc.

Distributed Corporation.......   Harbor Global Company Ltd., a Bermuda limited
                                 duration company and currently a wholly owned
                                 subsidiary of Pioneer Group

Securities to be
Distributed...................   Approximately 5,371,428 million Harbor Global
                                 common shares, based on the number of shares of
                                 Pioneer Group common stock outstanding on June
                                 22, 2000. The shares to be distributed will
                                 constitute all of the common shares of Harbor
                                 Global outstanding on the distribution date.

Distribution Ratio............   You will receive one Harbor Global common share
                                 for every five shares of Pioneer Group common
                                 stock you own on the distribution date.

Fractional Shares Interests...   Fractional Harbor Global common shares will not
                                 be distributed. The distribution agent will
                                 aggregate and seek to sell the fractional
                                 shares, and the aggregate net cash proceeds, if
                                 any, will be distributed pro rata to you, if
                                 you are entitled to a fractional interest.

Trading Market................   There is no current public trading market for
                                 Harbor Global common shares. The Harbor Global
                                 common shares are registered with the
                                 Securities and Exchange Commission and are
                                 transferable. However, Harbor Global common
                                 shares will not be listed on a securities
                                 exchange or on The Nasdaq Stock Market(R).
                                 Furthermore, Harbor Global does not intend to
                                 take any action to facilitate the development
                                 of an active trading market. Harbor Global
                                 cannot assure you that you will be able to sell
                                 your Harbor Global common shares, and if a
                                 trading market does develop, Harbor Global
                                 cannot assure you as to the prices at which

                                        approve and adopt the merger agreement
                                        between Pioneer Group and UniCredito

                                        and assets specified in the distribution
                                        agreement to Harbor Global;

                                      - all of the conditions to the obligation
                                        of Pioneer Group to close the merger,
                                        other than the condition that the
                                        distribution be completed, are satisfied
                                        or waived by Pioneer Group; and

                                      - no order, injunction or other legal

                                        distribution is in effect.

Distribution Agent............   EquiServe Limited Partnership

Dividend Policy...............   Harbor Global will distribute the proceeds it
                                 receives from the liquidation of its assets,
                                 net of its expenses, including amounts payable
                                 to Calypso Management under the administration
                                 and liquidation agreement, and net of other
                                 liabilities. The timing and amount of any
                                 distribution will also depend on the financial
                                 position and capital requirements of Harbor
                                 Global and other factors that the Harbor Global
                                 board of directors deems relevant.

Tax Consequences..............   Your receipt of cash and Harbor Global common
                                 shares in connection with the merger and the
                                 distribution will be a taxable transaction or
                                 transactions for United States federal income
                                 tax purposes and may also be subject to tax
                                 under applicable state, local and foreign tax
                                 laws.

                                 For federal income tax purposes, Pioneer Group
                                 currently estimates that it will report that
                                 the Harbor Global common shares received in the
                                 distribution have a value of approximately
                                 $[          ] to $[          ] with respect to
                                 each share of Pioneer Group common stock held
                                 at the time of the merger (equating to a value
                                 of the Harbor Global common shares of
                                 approximately $[          ] to $[          ]
                                 per share). However, the actual value ascribed
                                 to the Harbor Global common shares for federal
                                 income tax purposes may differ from this
                                 estimate due to, among other things, changes in
                                 the value of Harbor Global's assets before the
                                 date of the distribution and the number of
                                 shares of Pioneer Group common stock
                                 outstanding at the closing date of the merger.
                                 Pioneer Group and Harbor Global will provide
                                 you with their determination of the value of
                                 the Harbor Global common shares you will
                                 receive in the distribution. However, this
                                 determination will not be binding on the
                                 Internal Revenue Service, which may assert a
                                 different and possibly higher value for the
                                 Harbor Global common shares you receive.
                                 Accordingly, Harbor Global cannot assure you as
                                 to the

                                        3
<PAGE>   127

                                 exact amount of gain you may recognize as a
                                 result of the merger and the distribution.

                                 In addition, because Harbor Global intends to
                                 be treated as a partnership for United States
                                 federal income tax purposes, in general, you
                                 will recognize a proportionate share of Harbor
                                 Global's income, gain, loss and credits,
                                 including gain or loss from the sale of Harbor
                                 Global assets, determined in accordance with
                                 your interest in Harbor Global. You may also be
                                 required to recognize a proportionate share of
                                 the income earned by any Harbor Global
                                 subsidiary that is classified as a foreign
                                 personal holding company or a passive foreign
                                 investment company. You are urged to consider
                                 whether making a qualified electing fund
                                 election with respect to each passive foreign
                                 investment company would be beneficial to you.

                                 THE TAX CONSEQUENCES TO YOU OF THE DISTRIBUTION
                                 AND THE MERGER ARE COMPLEX AND WILL DEPEND ON
                                 YOUR PARTICULAR FACTS AND CIRCUMSTANCES. YOU
                                 ARE URGED TO CONSULT YOUR OWN TAX ADVISOR
                                 REGARDING THE SPECIFIC TAX CONSEQUENCES OF THE
                                 MERGER AND THE DISTRIBUTION, INCLUDING TAX
                                 RETURN REPORTING REQUIREMENTS, THE
                                 APPLICABILITY OF FEDERAL, STATE, LOCAL AND
                                 FOREIGN TAX LAWS AND THE EFFECT OF ANY PROPOSED
                                 CHANGE IN THE TAX LAWS. For a discussion of
                                 United States federal income tax consequences

                                 the qualified electing fund election, see the

Relationship with Pioneer
Group After the
  Distribution................   Following the distribution and the merger,
                                 Pioneer Group will not own any Harbor Global
                                 common shares. Harbor Global will operate as an
                                 independent public company, and Pioneer Group
                                 will operate as a wholly owned subsidiary of
                                 UniCredito Italiano. However, in connection
                                 with the distribution, Pioneer Group and Harbor
                                 Global entered into the following agreements:

                                   - Distribution agreement, under which:

                                     -- Pioneer Group will transfer some of its
                                        businesses and assets to Harbor Global;

                                     -- Pioneer Group will distribute Harbor
                                        Global common shares to its stockholders
                                        on a pro rata basis;

                                     -- Harbor Global will indemnify Pioneer
                                        Group for liabilities, other than tax
                                        liabilities, incurred by Pioneer Group
                                        relating to the businesses or operations
                                        of the Harbor Global assets; and

                                     -- Pioneer Group will indemnify Harbor
                                        Global for liabilities, other than tax
                                        liabilities, incurred by Harbor Global
                                        relating to the businesses or operations
                                        of the Pioneer Group assets, excluding
                                        the Harbor Global assets.

                                   - Tax separation agreement, under which
                                     Pioneer Group and Harbor Global will
                                     allocate tax liabilities that relate to
                                     periods before and after the distribution
                                     date.

                                 In addition, Pioneer Group and Harbor Global
                                 may enter into an agreement under which Pioneer
                                 Group may agree to provide corporate
                                 administrative, information and technology
                                 systems and other support to Harbor Global for
                                 a limited transition period.

Risk Factors..................   You should carefully read the section entitled
                                 "Risk Factors" in this information statement
                                 which describes risks and uncertainties
                                 associated with the Harbor Global common shares

                      SUMMARY PRO FORMA FINANCIAL DATA(1)

     The following table presents summary unaudited pro forma financial
information for Harbor Global. The summary pro forma condensed financial data
has been derived from Harbor Global's consolidated historical financial
statements for the three months ended March 31, 2000 and the year ended December
31, 1999, which are included elsewhere in this information statement. The
unaudited pro forma condensed consolidated statement of operations data sets
forth Harbor Global's results of operations for the year ended December 31,
1999, and the three months ended March 31, 2000, and assumes the distribution
was completed on January 1, 1999 or January 1, 2000, as applicable. The pro
forma condensed combined balance sheet data sets forth Harbor Global's financial
position at March 31, 2000, and assumes the distribution was completed on March
31, 2000.

     The pro forma adjustments are based upon available information and upon
certain assumptions that Harbor Global and Pioneer Group believe are reasonable
and which are described in the notes to the Pro Forma Condensed Consolidated
Financial Statements included in this information statement. The pro forma
condensed consolidated financial data is presented for informational purposes
only and may not be indicative of the results of operations or financial
position that would have occurred had the distribution occurred on the dates
indicated, or which may be obtained in the future, particularly in light of
Harbor Global's intent to liquidate its assets within a limited period of time.
You should read the pro forma condensed consolidated financial data presented
below in connection with the Pro Forma Condensed Consolidated Financial
Statements and the Consolidated Historical Financial Statements of Harbor Global
and the related notes included in this information statement.

                                  RISK FACTORS

HARBOR GLOBAL DOES NOT HAVE AN OPERATING HISTORY AS AN INDEPENDENT COMPANY.

     After the distribution, Pioneer Group will not own any Harbor Global common
shares, and Harbor Global will be an independent public company. Although Harbor
Global will be operated by the same senior management who operated its assets
prior to the distribution date, Harbor Global does not have an operating history
as an independent company. The financial statements included in this information
statement may not necessarily reflect the results of operations, financial
condition and cash flows that would have been achieved had Harbor Global and its
subsidiaries operated as an independent company during the periods presented,
particularly in light of Harbor Global's intent to liquidate its assets within a
limited period of time. In addition, as an independent company, Harbor Global
will not be able to rely on Pioneer Group for financial support or corporate
administrative support. After the distribution date, Harbor Global's operating
businesses will be responsible for obtaining their own financing, and Harbor
Global will be responsible for providing corporate administrative services,
including legal, human resources, information and technology systems and tax and
accounting services.

THE LOSS OF KEY OFFICERS AND MANAGERS COULD IMPAIR THE ABILITY OF HARBOR GLOBAL
TO SUCCESSFULLY OPERATE AND MANAGE ITS ASSETS PRIOR TO THEIR LIQUIDATION.

     After the distribution, Mr. Kasnet will be the President and Chief
Executive Officer, and Mr. Hunter will be the Chief Operating Officer and Chief
Financial Officer of Harbor Global. Mr. Kasnet is currently the President, and
Mr. Hunter is currently the Chief Operating Officer and Senior Vice President of
Pioneer Global Investments, a division of Pioneer Group. As executive officers
of Pioneer Global Investments, Mr. Kasnet and Mr. Hunter currently operate
substantially all the businesses that Harbor Global will own following the
distribution. In addition, Harbor Global is expected to enter into an
administration and liquidation agreement with Calypso Management under which
Calypso Management will manage the liquidation of Harbor Global and operate its
assets as going concern businesses until they are liquidated. Mr. Kasnet is the
President and Chief Executive Officer, and Mr. Hunter is the Chief Operating
Officer and Chief Financial Officer of Calypso Management.

     Harbor Global's assets are a diverse range of businesses and are generally
located in countries in which successfully conducting and selling businesses
requires significant experience. Harbor Global believes that its success in
liquidating its assets and operating its assets pending their liquidation will
depend to a significant extent upon the continued efforts of Mr. Kasnet and Mr.
Hunter. The loss of the services of either Mr. Kasnet or Mr. Hunter could have a
material adverse effect upon Harbor Global's results of operations and financial
condition. The services of Mr. Kasnet and Mr. Hunter may also be critical to
Harbor Global's ability to liquidate its assets at prices which will enable
Harbor Global to make meaningful distributions to its shareholders.

HARBOR GLOBAL'S BUSINESSES, PARTICULARLY THOSE CONDUCTED IN EMERGING MARKETS,
ARE SUSCEPTIBLE TO NUMEROUS RISKS AND UNCERTAINTIES ASSOCIATED WITH ITS
INTERNATIONAL OPERATIONS.

     Harbor Global conducts business in countries outside of the United States,
primarily in Russia and Poland. In the year ended December 31, 1999, nearly all
of Harbor Global's revenues were derived from operations outside of the United
States. Harbor Global will continue to operate its international businesses
until those businesses are liquidated and will continue to be subject to the
risks of doing business internationally, including:

     - unexpected changes in regulatory requirements and underdeveloped legal
       systems in some countries;

     - export controls relating to timber;

     - tariffs and other trade barriers;

     - difficulties in staffing and managing foreign operations;

     - political and economic instability;

                                        7
<PAGE>   131

     - fluctuations in currency exchange rates;

     - restrictions on currency exchange and repatriation;

     - restrictions on foreign investment in its businesses;

     - seasonal reductions in timber harvesting and gold exploration operations;
       and

     - potentially adverse tax consequences.

For example, in recent years Russia has undergone substantial political,
economic and social change. The economic conditions in Russia, together with
actions of the Russian government, led to a severe devaluation of the ruble, a
sharp increase in the rate of inflation, the near collapse of the banking
system, significant defaults on foreign currency obligations and a dramatic
decline in the prices of Russian debt and equity securities. In addition, as an
emerging market, Russia does not possess a well-developed business, legal and
regulatory infrastructure that would generally exist in the United States or in
a more mature free market economy. Accordingly, Harbor Global's Russian timber
harvesting and sales operations, gold exploration operations and real estate
management and investment management businesses involve significant risks, such
as those listed above, that are not typically associated with developed markets.
The liquidation of these businesses, and the businesses Harbor Global operates
in other emerging markets, as well as the successful operation of these
businesses pending their liquidation, will depend on the stability of, and
economic conditions in, these emerging markets.

HARBOR GLOBAL WILL INDEMNIFY PIONEER GROUP FOR SOME LIABILITIES ACCRUING AFTER
THE DISTRIBUTION DATE.

     Harbor Global and Pioneer Group have entered into a distribution agreement
under which Harbor Global agrees to indemnify Pioneer Group for liabilities,
other than tax liabilities, incurred by Pioneer Group relating to the businesses
or operations of the Harbor Global assets. For example, in connection with the
sale of its gold mining operations in Ghana to Ashanti Goldfields Teberebie
Limited, Pioneer Group has agreed to indemnify Ashanti for claims arising under
the purchase agreement before June 19, 2005 relating to its Ghanaian gold mining
operations. Under the distribution agreement, Pioneer Group has agreed to
transfer Pioneer Goldfields II Limited, the Pioneer Group subsidiary through
which Pioneer Group's gold mining operations in Ghana were conducted, to Harbor
Global. As a result of the transfer of Pioneer Goldfields II to Harbor Global,
Harbor Global is obligated to reimburse Pioneer Group in the event that Ashanti
seeks indemnification for any claim. Harbor Global's indemnification obligations
to Pioneer Group under the Ashanti purchase agreement are capped at the amount
of the total purchase price paid by Ashanti to Pioneer Goldfields II under the
purchase agreement.

     Additionally, under a tax separation agreement between Harbor Global and
Pioneer Group, generally, Harbor Global has agreed to indemnify Pioneer Group
for tax liabilities relating to the Harbor Global businesses. Currently, there
are no suits pending which would require payment by Harbor Global to Pioneer
Group under the indemnification provisions of the distribution agreement or tax
separation agreement. However, Harbor Global cannot assure you that no legal
proceeding or other claim will occur that would require Harbor Global to
indemnify Pioneer Group. Furthermore, Harbor Global and its subsidiaries may be
subject to legal proceedings or other claims arising in the ordinary course of
business, including employment related claims, environmental claims and
regulatory fees or fines associated with its international operations.

THE VALUES OF MOST OF HARBOR GLOBAL'S ASSETS ARE SPECULATIVE.

     The values of Harbor Global's gold exploration operations, Polish and
Eastern European real estate management operations and Russian real estate
management and investment management operations are speculative. Although Harbor
Global and its majority owned subsidiary Tas-Yurjah have conducted gold
exploration activities on its concession land, Harbor Global does not have
sufficient information to estimate the value of any proven or probable gold
reserves pursuant to United States reserves standards, and therefore Harbor
Global has not been able to evaluate the economic feasibility of, or begin,
extraction operations. Accordingly, the gold exploration business is not
producing a revenue stream. See "Business -- Russian Gold Exploration" for more
information about Harbor Global's gold exploration operations.
                                        8
<PAGE>   132

     Harbor Global's real estate management business consists principally of the
management of two pooled investment funds, the PBO Property Fund, LLC and the
Polish Real Estate Fund, S.A. Although Harbor Global believes that the PBO
Property Fund and the Polish Real Estate Fund could enhance the future value of
its real estate management business, the PBO Property Fund has received only a
small amount of funding from investors, and the Polish Real Estate Fund
committed capital is not yet invested. In addition, changes in real estate
values in Russia, Poland and Eastern Europe may also significantly affect the
value of these assets. See "Business -- Polish and Eastern European Real Estate"
for more information about Harbor Global's real estate management business.

     A significant portion of Harbor Global's Russian real estate management and
investment management operations consists of its approximately 52% interest in
Pioneer First Investment Fund, a company that invests in Russian real estate
and, to a lesser extent, securities of Russian companies. Generally, the Russian
real estate and securities markets are significantly smaller and less liquid
than the markets in the United States, and as a result, a portion of the assets
held by Pioneer First Investment Fund are illiquid. There is also limited
liquidity in the publicly traded securities of Pioneer First Investment Fund.
Consequently, Harbor Global may have difficulty selling its investment in
Pioneer First Investment Fund or causing Pioneer First Investment Fund to
liquidate its underlying assets, and may only be able to do so at prices which
may not reflect the long-term value of these investments. See
"Business -- Russian Real Estate and Investment Management" for more information
about Harbor Global's Russian real estate management and investment management
operations.

     Harbor Global sells the timber it harvests primarily to markets in the
Asian-Pacific region. During 1998, timber prices were significantly depressed
and, although prices increased in the last quarter of 1998 and in 1999, Harbor
Global cannot assure you that this trend will continue. The value of Harbor
Global's timber harvesting and sales operations is and will continue to be
affected by changes in market demand and prices for timber and upon the
stability of the economies in the Asian-Pacific region.

PIONEER FIRST INVESTMENT FUND IS CONSTRAINED IN DISTRIBUTING DIVIDENDS TO HARBOR
GLOBAL BECAUSE OF COST AND ADMINISTRATIVE BURDEN.

     Harbor Global holds approximately a 52% interest in Pioneer First
Investment Fund. Under Russian law, before paying a dividend to its
shareholders, Pioneer First Investment Fund must notify each shareholder by
mail. Currently, Pioneer First Investment Fund has over two million
shareholders. The administrative and postage expenses associated with notifying
its shareholders would consume a significant portion of any dividend. Pioneer
First Investment Fund established a share repurchase program to reduce the
number of its shareholders, but the program has had little success. Until its
efforts to lessen these burdens are successful, the large number of shareholders
constrains Pioneer First Investment Fund from paying dividends to its
shareholders, including Harbor Global.

THE AMOUNT OF INCOME, GAIN OR LOSS YOU MAY RECOGNIZE AS A RESULT OF THE MERGER
AND DISTRIBUTION CANNOT BE PRECISELY DETERMINED.

     Your receipt of cash and Harbor Global common shares in connection with the
merger and the distribution will be a taxable transaction or transactions. The
amount of income, gain or loss, if any, that you will recognize will depend, in
part, on the fair market value of the Harbor Global common shares you receive in
the distribution. Harbor Global will undertake to provide you with its
determination regarding the fair market value of the Harbor Global common shares
you receive in the distribution. However, any determination will not be binding
on the Internal Revenue Service, which may assert a different and possibly
higher value for the Harbor Global common shares you receive. Accordingly, there
can be no assurance as to the exact amount of income, gain or loss you may
recognize as a result of the merger and the distribution.

AS A RESULT OF HOLDING HARBOR GLOBAL COMMON SHARES, YOU MAY RECOGNIZE TAXABLE
INCOME AND BE REQUIRED TO PAY TAX WITHOUT A CORRESPONDING DISTRIBUTION OF CASH
FROM HARBOR GLOBAL TO YOU.

     For United States federal income tax purposes, Harbor Global will file an
election to be classified as a partnership. For United States federal income tax
purposes, it is anticipated that you will be treated as a
                                        9
<PAGE>   133

partner in a Bermuda partnership and your Harbor Global common shares will
represent partnership interests. Because of its classification as a partnership
for United States federal income tax purposes, Harbor Global will not itself be
subject to United States federal income tax. Instead, items of income, gain,
loss, deduction and expense will flow through to you, and you will include your
allocable share of these items in computing your own United States federal
income tax for each taxable year of Harbor Global. Cash distributions made by
Harbor Global to you generally will not be taxable, except to the extent that
those distributions exceed your adjusted tax basis in the Harbor Global common
shares. For a general discussion of the rules regarding certain tax consequences
of holding Harbor Global common shares, see the discussion under the heading
"The Distribution -- Certain United States Federal Income Tax
Consequences -- United States Federal Income Tax Consequences of Holding Harbor
Global Common Shares" in this information statement.

     Harbor Global believes that one or more of the majority or minority owned
foreign subsidiaries of Harbor Global may be classified as a foreign personal
holding company or passive foreign investment company for United States federal
income tax purposes. If any such subsidiary is classified as a foreign personal
holding company or passive foreign investment company, you may be required to
recognize taxable income and pay tax with respect to a portion of the
subsidiary's income, even in the absence of the receipt of any payment of cash
or other property from the subsidiary. The tax rules regarding foreign
partnerships, foreign personal holding companies and passive foreign investment
companies are complicated. You should consult your tax advisor to determine the
tax consequences to you of holding Harbor Global common shares. For a general
discussion of the rules regarding foreign personal holding companies and passive
foreign investment companies, see "The Distribution -- Certain United States
Federal Income Tax Consequences -- Investments in Foreign Corporations."

THERE IS NOT, NOR CAN YOU EXPECT THERE TO BE, AN ACTIVE PUBLIC TRADING MARKET
FOR HARBOR GLOBAL COMMON SHARES.

     Prior to the distribution, there has been no public trading market for
Harbor Global common shares. In addition, Harbor Global cannot assure you that
an active public trading market will develop after the distribution because
Harbor Global common shares will not be listed on any securities exchange or on
The Nasdaq Stock Market(R).

     Furthermore, Harbor Global does not intend to:

     - engage the services of any market maker;

     - facilitate the development of an active public trading market in Harbor
       Global common shares, or encourage others to do so;

     - place any advertisements in the media promoting an investment in Harbor
       Global; or

     - except as required by the Securities Exchange Act of 1934, collect or
       publish information about prices at which Harbor Global common shares may
       be traded.

     Harbor Global cannot assure you that you will be able to sell the Harbor
Global common shares you will receive in the distribution. If a trading market
does develop, Harbor Global cannot assure you as to the prices at which Harbor
Global common shares will trade.

HARBOR GLOBAL AND THE BUSINESSES IT OPERATES MAY NOT BE ABLE TO RAISE ADDITIONAL
CAPITAL OR OBTAIN DEBT FINANCING.

     Based on budget projections, Harbor Global Company Ltd. currently has
sufficient capital, without liquidating any of its assets, to continue to
operate its assets for approximately three years. As such, it may be necessary
for Harbor Global to liquidate some of its assets within three years of the
distribution date to continue to operate its remaining assets pending their
liquidation. If Harbor Global is unable to liquidate some of its assets, it will
require additional funding. Harbor Global may not be able to obtain additional
funding, either in the form of additional capital or debt financing, because of
the nature of its operations, namely its intent to hold its assets for
liquidation and its limited duration. In addition, after the

                                       10
<PAGE>   134

distribution and the merger, Pioneer Group will not own any Harbor Global common
shares, and Pioneer Group and Harbor Global will operate as two wholly
independent companies. As an independent company, Harbor Global will not be able
to obtain additional funding from Pioneer Group. If adequate funding is not
available, Harbor Global may be forced to liquidate its assets prematurely for a
discounted sale price or on other less favorable terms than those that may
otherwise be available if Harbor Global could obtain additional funding.

HARBOR GLOBAL WILL BE SUBJECT TO SIGNIFICANT RESTRICTIONS IF IT BECOMES AN
INVESTMENT COMPANY.

     Harbor Global is currently not an investment company. Because a portion of
Harbor Global's assets consists of investment securities, Harbor Global could,
in some circumstances in the future, be deemed to be an investment company under
the Investment Company Act of 1940. The determination of whether Harbor Global
is an investment company is based on facts and circumstances that exist at
various times.

     Harbor Global intends to conduct itself in the future so as to avoid
becoming an investment company. If, nevertheless, Harbor Global were in the
future to become an investment company, because Harbor Global is a foreign
company, the Investment Company Act would prohibit Harbor Global and any person
deemed to be an underwriter of Harbor Global's securities from offering for
sale, selling or delivering after sale, in connection with a public offering,
any security issued by Harbor Global in the United States.

                                THE DISTRIBUTION

REASONS FOR THE DISTRIBUTION

     On May 14, 2000, Pioneer Group and UniCredito Italiano entered into a
merger agreement under which a wholly owned subsidiary of UniCredito Italiano
will merge with and into Pioneer Group. Pioneer Group will survive the merger as
a wholly owned subsidiary of UniCredito Italiano. Prior to closing the merger,
Pioneer Group will transfer some of its businesses and assets to Harbor Global,
a wholly owned subsidiary of Pioneer Group, and distribute Harbor Global common
shares to its stockholders. The Pioneer Group board of directors believes the
distribution will enable Pioneer Group stockholders to participate in the value
of all of Pioneer Group's assets through the acquisition of Pioneer Group by
UniCredito Italiano and the realization of any potential value of the businesses
and assets transferred to Harbor Global through the liquidation of those assets
within a limited period of time. Pioneer Group's board of directors believes the
distribution and the merger are in the best interests of Pioneer Group's
stockholders.

DISTRIBUTION AGREEMENT

     Pioneer Group and Harbor Global have entered into a distribution agreement
which, in general, provides that:

     - Pioneer Group will transfer some of its businesses and assets to Harbor
       Global;

     - Pioneer Group will distribute Harbor Global common shares to its
       stockholders on a pro rata basis;

     - Harbor Global will indemnify Pioneer Group for liabilities, other than
       tax liabilities, incurred by Pioneer Group relating to the business or
       operations of Harbor Global or its subsidiaries; and

     - Pioneer Group will indemnify Harbor Global for liabilities, other than
       tax liabilities, incurred by Harbor Global relating to the business or
       operations of Pioneer Group or its subsidiaries, excluding Harbor Global
       and its subsidiaries.

The form of distribution agreement is attached as Exhibit A to this information
statement.

     Transfer of Assets.  Under the distribution agreement, Pioneer Group has
agreed to transfer the capital stock of several of its subsidiaries and an
amount in cash of $25 million to Harbor Global before the distribution date. As
a result of these transfers, at the time of the distribution Harbor Global's
assets will consist primarily of the following businesses and assets currently
owned or operated by Pioneer Group:

     - real estate management and investment management operations in Russia;

     - Polish and Eastern European venture capital investment and management
       operations;

     - Polish and Eastern European real estate management operations;

     - timber harvesting and sales in Russia;

     - gold exploration operations in Russia;

     - the proceeds from the sale of Pioneer Group's gold mining operations in
       Ghana; and

     - $25 million in cash.

Harbor Global will own and operate all of its assets through a direct majority
owned subsidiary, Harbor Global II Ltd. See "Business -- Holding Company
Structure" in this information statement for more information about Harbor
Global's structure.

     Indemnification.  In connection with the transfer of the Pioneer Group
businesses and assets described above to Harbor Global, Harbor Global has agreed
to indemnify Pioneer Group and its subsidiaries and their officers, directors,
agents and employees for liabilities, other than tax liabilities, incurred by
Pioneer Group relating to the businesses or operations of Harbor Global or its
subsidiaries. For example, in connection with the sale of its gold mining
operations in Ghana to Ashanti Goldfields

                                       12
<PAGE>   136

Teberebie Limited, Pioneer Group has agreed to indemnify Ashanti for claims
arising under the purchase agreement before June 19, 2005 relating to its
Ghanaian gold mining operations. Under the distribution agreement, Pioneer Group
has agreed to transfer Pioneer Goldfields II Limited, the Pioneer Group
subsidiary through which Pioneer Group's gold mining operations in Ghana were
conducted, to Harbor Global. As a result of the transfer of Pioneer Goldfields
II to Harbor Global, Harbor Global is obligated to reimburse Pioneer Group in
the event that Pioneer Group indemnifies Ashanti for any claim under the
purchase agreement.

     Similarly, under the distribution agreement, Pioneer Group has agreed to
indemnify Harbor Global and its subsidiaries and their directors, officers,
agents and employees for liabilities, other than tax liabilities, incurred by
Harbor Global relating to the businesses or operations of Pioneer Group or its
subsidiaries, other than Harbor Global and its subsidiaries.

     The liability of each of Harbor Global and Pioneer Group for taxes are
exclusively governed by the tax separation agreement which is described below.

     Additional Liabilities.  Under the purchase agreement in connection with
the sale by Pioneer Group of its gold mining operations in Ghana to Ashanti,
Pioneer Goldfields II is entitled to receive an $18.8 million base purchase
price plus additional payments up to $5 million contingent upon the market price
of gold and productivity of the Ghana gold mine. On June 19, 2000, $5 million of
the base purchase price was paid to Pioneer Goldfields II in cash and $13.8
million of the base purchase price was paid in the form of a five year
non-interest bearing promissory note. Under the distribution agreement, Harbor
Global has agreed that promptly after June 19, 2005, the fifth anniversary of
the closing of the sale, it will pay to Pioneer Group the lesser of $5 million
or the proceeds received by Pioneer Goldfields II from Ashanti under the
purchase agreement less any indemnification claims paid under the purchase
agreement for breach of any representation or warranty of Pioneer Goldfields II,
which shall not exceed the total purchase price paid by Ashanti. If any
indemnification claim under the purchase agreement is pending on June 19, 2005,
Harbor Global will pay the appropriate amount described above promptly upon
resolution of the pending claim or claims. For more information about the
transaction with Ashanti, see "Business -- Other Assets -- Ashanti Proceeds" in
this information statement.

     Harbor Global will make certain payments to Mr. Hunter, Catherine V.
Mannick and other employees of Calypso Management or subsidiaries of Harbor
Global who are currently officers or employees of Pioneer Group or its
subsidiaries and who, as a result of the merger, will be entitled to receive
payments from Pioneer Group upon termination of their employment with Pioneer
Group. In addition, Harbor Global will pay Mr. Kasnet a signing and retention
bonus of $1.8 million if he remains employed by Calypso Management and Calypso
Management continues to provide services to Harbor Global on the second
anniversary of the distribution date, or if Harbor Global terminates his
employment without cause prior to the second anniversary of the distribution
date. Harbor Global expects that these payments will be approximately $3.6
million in the aggregate. See "Management -- Compensation of Executive Officers"
in this information statement for more information regarding these payments.

     In addition, Harbor Global has commitments to invest an additional
approximately $5.4 million in the Polish Real Estate Fund and approximately $2.3
million in the PBO Property Fund. See "Business -- Polish and Eastern European
Real Estate" in this information statement for more information regarding the
Polish Real Estate Fund and the PBO Property Fund.

     Intercompany Indebtedness.  Prior to the distribution, any intercompany
indebtedness, receivable or other intercompany obligation between Harbor Global
or its subsidiaries on one hand, and Pioneer Group or its subsidiaries on the
other hand, other than Pioneer Group's right to receive up to $5 million under
the distribution agreement in connection with the Ashanti purchase agreement,
will be contributed by Pioneer Group to the capital of either Harbor Global or
one of its subsidiaries. Following the distribution, except as described above
and except for any amounts payable by Harbor Global to Pioneer Group in
connection with any transitional services provided to Harbor Global, there will
be no outstanding indebtedness or accounts payable or receivable between Harbor
Global and its subsidiaries and Pioneer Group and its subsidiaries.
                                       13
<PAGE>   137

     Mutual Release.  Under the distribution agreement each of Harbor Global and
Pioneer Group releases and forever discharges the other and its subsidiaries for
all obligations, liabilities and claims which the releasing party has against
the other relating to events or circumstances existing before the distribution
date. This mutual release does not affect either party's ability to enforce the
distribution agreement or any other agreement contemplated by the distribution
agreement, including the tax separation agreement.

     Names.  Following the distribution, the name "Pioneer" and all similar
related names, marks and logos will be the property of UniCredito Italiano,
Pioneer Group or a subsidiary of Pioneer Group. Harbor Global intends to change
the names of its subsidiaries that currently contain the "Pioneer" name before
the distribution. Accordingly, the names of some of the Harbor Global
subsidiaries used in this information statement will be changed. In the event
that these name changes cannot be completed before the distribution date,
Pioneer Group and Harbor Global have agreed to use their good faith efforts to
enter into a licence agreement to permit Harbor Global and its subsidiaries to
use the "Pioneer" name for a reasonable period of time after the closing of the
merger in connection with the continued operation of Harbor Global's assets and
businesses.

     Distribution of Harbor Global Common Shares.  The distribution agreement
provides that the distribution record date and the distribution date will be the
closing date of the merger and that the distribution will occur immediately
prior to the closing of the merger.

     The distribution will occur only if the following conditions are satisfied:

     - the stockholders of Pioneer Group approve and adopt the merger agreement
       between Pioneer Group and UniCredito Italiano;

     - Pioneer Group transfers some of its businesses and assets to Harbor
       Global;

     - all of the conditions to the obligation of Pioneer Group to close the
       merger, other than the condition that the distribution be completed, are
       satisfied or waived by Pioneer Group; and

     - no order, injunction or other legal restraint preventing or prohibiting
       the distribution is in effect.

     Pioneer Group will deliver to EquiServe Limited Partnership, the
distribution agent, certificates representing all of the outstanding Harbor
Global common shares. At the time of distribution, Pioneer Group will notify the
distribution agent that the distribution is effective, and you will be entitled
to receive one Harbor Global common share for every five shares of Pioneer Group
common stock held by you on the distribution date. No certificates or scrip
representing fractional Harbor Global common shares will be issued to you as
part of the distribution. The distribution agent will aggregate fractional
shares into whole shares and seek to sell them at then prevailing prices on
behalf of you and other holders who would be entitled to receive fractional
share interests. Instead of a fractional share, you will receive a cash payment
in the amount of your pro rata share of the total sale proceeds, net of any
commissions incurred in connection with the sale of fractional shares. The
aggregated fractional shares will be sold on, or as soon as practicable after,
the distribution date.

     The total number of Harbor Global common shares to be distributed will
depend on the number of shares of common stock of Pioneer Group outstanding on
the distribution date. Based upon the number of shares of Pioneer Group
outstanding on June 22, 2000, approximately 5,371,428 Harbor Global common
shares will be distributed to Pioneer Group stockholders. This amount may
increase prior to the distribution date due to the issuance of shares of Pioneer
Group common stock upon the exercise of outstanding options. The certificate
representing your Harbor Global common shares will be mailed to you
approximately one to two weeks after the distribution date.

     You will not be required to pay any cash or other consideration for the
Harbor Global common shares you receive in the distribution.

TAX SEPARATION AGREEMENT

     Pioneer Group and Harbor Global have entered into a tax separation
agreement, which will govern each party's rights and obligations with respect to
payments, deficiencies and refunds, if any, of federal, state, local or foreign
taxes for periods before and after the distribution. Under the tax separation
agreement, Harbor Global has agreed to pay any tax arising in connection with
the transfer of businesses and assets from Pioneer Group to Harbor Global and
the subsequent distribution. The tax separation agreement also governs each
party's obligations with respect to the filing of tax returns and conduct of tax
audits. The form of the tax separation agreement is attached as Exhibit B to
this information statement.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

     The following is a general description of certain United States federal
income tax consequences that are expected to be material and are applicable to
you by virtue of your receipt of cash and Harbor Global common shares in the
merger and distribution. This description is not a comprehensive description of
all of the tax consequences that may be relevant to you. This description does
not discuss the tax consequences that may be applicable to you in light of your
individual circumstances or if you are subject to special treatment under some
United States federal income tax laws, such as laws pertaining to:

     - banks;

     - tax-exempt organizations;

     - insurance companies;

     - mutual funds;

     - traders in securities who elect to apply a mark-to-market method of
       accounting;

     - dealers in securities or foreign currencies;

     - stockholders who received their Pioneer Group common stock through the
       exercise of employee stock options or otherwise as compensation;

     - stockholders who are not United States persons, as defined in the
       Internal Revenue Code;

     - stockholders who hold Pioneer Group common stock as part of a hedge,
       straddle or conversion transaction;

     - stockholders who hold Pioneer Group common stock through a partnership,
       trust or other entity that is treated as a pass-through entity for United
       States federal income tax purposes; or

     - stockholders subject to the alternative minimum tax.

     This description is based upon the Internal Revenue Code of 1986, the
regulations of the United States Treasury Department, and court and
administrative rulings and decisions in effect on the date of this information
statement, all of which are subject to change, possibly retroactively, which may
change the tax consequences described below.

     Neither Harbor Global nor Pioneer Group has sought or will seek a ruling
from the Internal Revenue Service or a legal opinion regarding any tax matter
discussed in this information statement, including any tax consequences relating
to the formation of Harbor Global, or the tax consequences of the merger and
distribution or holding Harbor Global common shares. Neither Pioneer Group nor
Harbor Global can assure you that the Internal Revenue Service would not assert,
or that a court would not sustain, a position contrary to any of the tax
consequences described below.

     Tax matters are complicated. The tax consequences of the merger and the
distribution to you are complex and will depend on your particular facts and
circumstances. Harbor Global urges you to consult your own tax advisor regarding
your specific tax consequences of the merger and distribution, including tax
return reporting requirements, the applicability of federal, state, local and
foreign tax laws and the effect of any proposed change in the tax laws.

     U.S. Federal Income Tax Consequences to Pioneer Group Stockholders of the
Receipt of Cash and Harbor Global Common Shares.  The United States federal
income tax consequences to you of receiving Harbor Global common shares in the
distribution may differ significantly depending on whether the distribution and
merger are treated as a single integrated transaction or as two separate
transactions for United States federal income tax purposes. Although there is no
specific authority directly on point, UniCredito Italiano, Pioneer Group and
Harbor Global intend to characterize the merger and the distribution as a single
integrated transaction for United States federal income tax purposes. However,
because the issue is not free from doubt, you should consult your tax advisor
with respect to the proper treatment of the distribution of Harbor Global common
shares.

     In general, your receipt of cash and Harbor Global common shares in
connection with the merger and the distribution will be a taxable event. If the
merger and the distribution are treated as a single, integrated transaction,
your receipt of cash and Harbor Global common shares will be treated as an
exchange of shares of Pioneer Group common stock for both cash and Harbor Global
common shares. Under this treatment, you will generally recognize capital gain
or loss for United States federal income tax purposes equal to the difference
between (1) the amount of cash you receive plus the fair market value at the
time of the distribution of the Harbor Global common shares you receive and (2)
the adjusted tax basis in the shares of Pioneer Group common stock you surrender
in exchange for the cash and Harbor Global common shares.

     The gain or loss will be long-term capital gain or loss if your holding
period for the Pioneer Group common stock you exchange is more than 12 months at
the closing of the merger. If you own more than one block of shares of Pioneer
Group common stock, the cash and Harbor Global common shares you receive must be
allocated ratably among the blocks you own. Your holding period for the Harbor
Global common shares you receive in the distribution will begin on the day
following the date of the distribution, and you will have an initial tax basis
in the Harbor Global common shares equal to their fair market value on the
distribution date.

     If the merger and distribution are not treated as a single integrated
transaction for United States federal income tax purposes, the receipt of cash
in exchange for shares of Pioneer Group common stock would result in the
recognition of gain or loss as described above, while your receipt of Harbor
Global common shares may instead be a taxable distribution from Pioneer Group.

     If the receipt of the Harbor Global common shares were treated as a taxable
distribution, the fair market value of your Harbor Global common shares at the
time of the distribution would be taxable to you as a dividend to the extent of
Pioneer Group's current or accumulated earnings and profits, including earnings
and profits arising from the deemed sale by Pioneer Group of the Harbor Global
common shares as a result of the distribution. That portion of the value of
Harbor Global common shares that exceeds the earnings and profits of Pioneer
Group would first be treated as a non-taxable return of capital to the extent of
your basis in your shares of Pioneer Group common stock, and your adjusted tax
basis in this stock would be reduced accordingly (but not below zero). To the
extent that the remaining portion of the value of Harbor Global common shares
you receive were to exceed your adjusted tax basis in your shares of Pioneer
Group common stock, the excess would be treated as long-term or short-term
capital gain from the sale or exchange of Pioneer Group common stock, depending
on the period of time you held the Pioneer Group stock.

     As discussed above, the amount of income, gain or loss, if any, that you
will recognize will depend, in part, on the fair market value of the Harbor
Global common shares you receive in the distribution. Harbor Global will
undertake to provide you with its determination regarding the fair market value
of the Harbor Global common shares you receive in the distribution. However, any
determination will not be binding on the Internal Revenue Service, which may
assert a different, and possibly higher, value for the Harbor Global common
shares you receive. Accordingly, there can be no assurance as to the exact
amount of income, gain or loss you may recognize as a result of the merger and
the distribution.

     Bermuda and United States Tax Status of Harbor Global.  Harbor Global
believes that it will not be subject to taxation in Bermuda and that interest,
dividends and gains distributed by Harbor Global to you will not be subject to
taxation in Bermuda.

     For United States federal income tax purposes, Harbor Global will elect to
be classified as a partnership. Harbor Global believes that it will not be
classified as a "publicly traded partnership" or otherwise classified as a
corporation for United States federal income tax purposes. It is anticipated
that, for United States federal income tax purposes, you will be treated as a
partner in the Bermuda partnership and your Harbor Global common shares will
represent partnership interests.

     United States Federal Income Tax Consequences of Holding Harbor Global
Common Shares.  By reason of its classification as a partnership for United
States federal income tax purposes, Harbor Global itself will not be subject to
United States federal income tax. Instead, items of income, gain, loss,
deduction and expense will pass through to you, and you will be treated as a
partner in Harbor Global for United States federal income tax purposes.

     As a partner in Harbor Global, you will be required to take into account
your allocable share of Harbor Global's items of income, gain, loss, deduction
and credit. The amount of your allocable share of Harbor Global's items of
income, gain, loss, deduction and credit will be determined in accordance with
your interest in Harbor Global. Your adjusted tax basis in the Harbor Global
shares generally will be equal to the fair market value of the Harbor Global
shares you receive at the time of the distribution and will be (1) increased by
your allocable share of Harbor Global's items of income and gain that you are
required to take into account as described above and (2) decreased, but not
below zero, by the allocable share of Harbor Global's items of deduction and
loss and the amount of any cash or other distribution made by Harbor Global to
you. Cash distributions that Harbor Global makes to you generally will not be
taxable to you, except to the extent that these distributions exceed your
adjusted tax basis in your Harbor Global common shares.

     Because Harbor Global will not be required to make current distributions of
its earnings, it is possible that your United States federal income tax
liability directly (as described below under the heading "Investments in Foreign
Corporations"), or with respect to your allocable share of Harbor Global's items
of income, gain, loss, deduction and credit, in a particular taxable year could
exceed the cash distributions, if any, to you for that year. In this case, you
may have a liability for tax which must be paid by you out of other funds.

     Harbor Global's disposition of businesses or assets may generally give rise
to income, gain or loss, which will pass through to you, as described above.
Except as described below under the heading "Passive Foreign Investment
Company," this gain will be treated as long-term capital gain if Harbor Global's
holding period in the stock is more than 12 months at the time of the sale. For
this purpose, Harbor Global's holding period will include any period during
which the stock was held as a capital asset by Pioneer Group. Harbor Global
expects to distribute proceeds from the liquidation of its assets, net of its
expenses and other liabilities, pro rata to its shareholders.

     Investments in Foreign Corporations.  As a result of the structure of
Harbor Global, you may be required to recognize a proportionate share of the
income earned by any majority or minority owned Harbor Global subsidiary that is
classified as a Foreign Personal Holding Company or a Passive Foreign Investment
Company. You are urged to consult your tax advisor as to whether making a
qualified electing fund election, as described below, with respect to each
Passive Foreign Investment Company would be beneficial to you.

     Foreign Personal Holding Company.  Harbor Global believes that one or more
of its foreign subsidiaries may be classified as a "foreign personal holding
company" (an "FPHC"). In general, a foreign corporation will be classified as an
FPHC if in any taxable year (1) five or fewer individuals who are United States
citizens or residents own or are deemed to own more than 50% (measured by the
total voting power of all classes entitled to vote or the total value) of the
foreign corporation's shares (the "ownership test") and (2) at least 60% (50% in
some cases) of the foreign corporation's gross income

                                       17
<PAGE>   141

consists of "foreign personal holding company income," which generally includes
passive income such as dividends, interests, gains from the sale or exchange of
shares or securities, rent and royalties (the "income test").

     For purposes of determining whether a foreign corporation meets the
ownership test described above, you will be treated as owning your proportionate
share of stock in any foreign corporation held by Harbor Global, and the shares
that are treated as owned by you will be attributed to all other shareholders of
Harbor Global. Therefore, any foreign corporation owned by Harbor Global will
generally be treated as owned, through attribution, by each Harbor Global
shareholder in the same proportion that the company is owned by Harbor Global,
so that the ownership test will be satisfied with respect to any company that is
owned more than 50 percent by Harbor Global. As a result, any foreign
corporation that is more than 50% owned by Harbor Global will be treated as an
FPHC based solely on whether the income test is satisfied. In addition, Harbor
Global believes that one or more of the subsidiaries of Harbor Global will have
substantial passive income, and as a result may be classified as an FPHC under
the income test.

     In the event that any foreign subsidiary of Harbor Global is classified as
an FPHC, you will be required to include your proportionate share of the
subsidiary's undistributed foreign personal holding company income, regardless
of whether you receive corresponding distributions of cash.

     Harbor Global will undertake to provide you with information regarding the
classification of any Harbor Global subsidiary as an FPHC and your allocable
share of the subsidiary's income, as described above. However, Harbor Global
cannot assure you that it will be able to provide you with this information.

     Passive Foreign Investment Company.  One or more of Harbor Global's
subsidiaries could also be classified as a passive foreign investment company (a
"PFIC"). In general, a foreign corporation will be a PFIC if, for any taxable
year, either (1) 75% or more of its gross income is "passive income," which
includes interest, dividends, and some types of rents and royalties, or (2) the
average percentage of the corporation's assets that produce or are held for the
production of "passive income" is 50% or more. If any of the foreign
corporations owned directly or indirectly by Harbor Global is a PFIC during any
year in which you own an interest in Harbor Global, you will be treated as
directly owning your proportionate share of such PFIC. Unless you make a
qualified electing fund election, as described below, you will be subject to tax
on gains on dispositions of PFIC shares by Harbor Global or a subsidiary of
Harbor Global and on certain "excess distributions" by a PFIC to Harbor Global
as if the gain or distribution were ordinary income earned ratably over each of
the years during the period in which the subsidiary was classified as a PFIC,
and you will be treated as owning an indirect interest in the PFIC. You
generally will be liable to pay tax at the ordinary income rates prevailing
during each of the years to which the gain or distribution is allocated, except
that in the case of gains and distributions allocated to prior years in which
the foreign corporation was a PFIC, (1) the tax rate will be the highest in
effect for that taxable year and (2) the tax will be payable generally without
regard to offsets from deductions, losses and expenses. You will also be subject
to an interest charge with respect to any tax described above that is allocated
to a prior year.

     Alternatively, you may make an election with respect to each PFIC in which
you are treated as owning shares to have the PFIC treated as a "qualified
electing fund" ("QEF"). In general, a QEF election would require you to include
in gross income each year your share of the PFIC's ordinary income and net
capital gain for the year, even if the PFIC does not distribute cash or other
property in respect of such income. You may only make a QEF election if the PFIC
satisfies certain reporting requirements with respect to its ordinary income and
net capital gains.

     In addition, subject to specific limitations, shareholders treated as
owning marketable shares in a PFIC may make an election to mark those shares to
market annually, rather than being subject to the above-described rules. Amounts
included in or deducted from income under this mark-to-market election and
actual gains and losses realized upon disposition, subject to specific
limitations, would be treated as ordinary gains or losses.

                                       18
<PAGE>   142

     As mentioned above, Harbor Global expects that one or more of its
subsidiaries will have substantial passive income. Accordingly, Harbor Global
expects that one or more of its subsidiaries will be classified as a PFIC, in
which case the subsidiary will likely be classified as both a PFIC and an FPHC.
In that event, unless you make a QEF election, you will include in your income
the portion of the foreign corporation's income that is required to be included
under the FPHC rules, described above, and also be subject to tax under the PFIC
rules with respect to gains on dispositions and excess distributions, including
the interest charge, as described above. However, if you have made a QEF
election with respect to a company that is treated as both a PFIC and an FPHC,
you will include in your income your proportionate share of the foreign
corporation's income as provided in the FPHC rules, as described above, and any
remaining income under the QEF rules, as described above. Accordingly, you will
include your proportionate share of the subsidiary's income, but only once, and
you will not be subject to the PFIC rules regarding gains on dispositions and
excess distributions, including the interest charge described above in the PFIC
rules.

     Harbor Global will undertake to obtain from any PFIC, and provide to you,
the information necessary to allow you to make, and maintain, a QEF election
with respect to any PFIC. However, Harbor Global cannot assure you that it will
be able to provide all the necessary information to satisfy the PFIC
requirements and that you will be permitted to make and maintain a QEF election.

     YOU ARE STRONGLY URGED TO CONSULT YOUR TAX ADVISOR WITH RESPECT TO HOW THE
PASSIVE FOREIGN INVESTMENT COMPANY RULES AFFECT YOUR TAX SITUATION AND WHETHER
MAKING A QUALIFIED ELECTING FUND ELECTION WITH RESPECT TO EACH PASSIVE FOREIGN
INVESTMENT COMPANY OWNED BY HARBOR GLOBAL WOULD BE BENEFICIAL TO YOU.

     Controlled Foreign Corporation.  Any foreign corporation that is held
directly or indirectly by Harbor Global could be treated as a "controlled
foreign corporation" if more than 50% of the total voting power or value of the
shares is owned, directly or indirectly, by shareholders that are citizens or
residents of the United States, United States domestic partnerships or
corporations or estates or trusts other than foreign estates or trusts,
indirectly owning 10% or more of the total combined voting power of all classes
of shares in the foreign corporation. This classification would have many
complex results, including requiring the shareholders to include in income their
pro rata shares of the controlled foreign corporation's "Subpart F Income," as
defined by the Internal Revenue Code. In addition, with respect to any such
shareholder who is or was a 10% or greater shareholder at any time during the
five year period ending with the sale or exchange of shares in a controlled
foreign corporation by Harbor Global or any of its subsidiaries, gain from such
sale or exchange will be treated as a dividend taxable at ordinary income tax
rates to the extent of the controlled foreign corporation's earnings and profits
attributable to the shares sold or exchanged.

     Pioneer Group does not believe that any foreign corporation that will be
held directly or indirectly by Harbor Global immediately following the
distribution will be a controlled foreign corporation. However, we cannot assure
you that a foreign corporation owned by Harbor Global will not qualify as a
controlled foreign corporation in the future.

TRADING OF HARBOR GLOBAL COMMON SHARES

     Harbor Global has registered its common shares with the Securities and
Exchange Commission on a registration statement on Form 10 under the Securities
Exchange Act of 1934, effective as of [            ], 2000. The Harbor Global
common shares you receive in the distribution will be freely transferable,
unless you are an "affiliate" of Harbor Global under the Securities Act of 1933.
However, there is no current public trading market for Harbor Global common
shares, and Harbor Global common shares will not be listed on an exchange or on
The Nasdaq Stock Market(R). Furthermore, Harbor Global does not intend to take
any action to facilitate the development of an active trading market. Harbor
Global cannot assure you that you will be able to sell your Harbor Global common
shares, and if a trading market does develop, Harbor Global cannot assure you as
to the prices at which Harbor Global common shares will trade.

     Persons who may be deemed to be affiliates of Harbor Global generally
include individuals or entities that control, are controlled by or are under
common control with Harbor Global and may include the directors and officers of
Harbor Global or any principal shareholder of Harbor Global. Persons who are
affiliates of Harbor Global will be permitted to sell their Harbor Global common
shares only pursuant to an effective registration statement under the Securities
Act or an exemption from the registration requirements of the Securities Act,
such as the exemption afforded under Rule 144 under the Securities Act.

(1) Reflects the contribution of cash by the Pioneer Group of approximately
    $29,080,000 which includes: (1) $25,000,000 to fund the expenses to be
    incurred by Harbor Global for the administration and liquidation of its
    assets, to fund capital commitments to the PBO Property Fund and the Polish
    Real Estate Fund and to fund certain compensation liabilities payable to
    current employees of Pioneer Group who will become employees of Harbor
    Global or its subsidiaries or Calypso Management; and (2) $4,080,000 to fund
    the repayment of a note payable of Forest-Starma prior to the distribution.
    Also reflects $5,000,000 of cash received by Pioneer Goldfields II, which
    will become a wholly owned subsidiary of Harbor Global, in connection with
    the sale of its Ghanaian gold mining operations. Approximately $8,600,000 of
    the cash is reflected in short and long term restricted cash.

(2) Reflects the repayment of $4,960,000 of notes payable to occur prior to the
    distribution. Pioneer Group will contribute $4,080,000 to the repayment, and
    Harbor Global will fund the balance of $880,000.

(3) Reflects the capitalization of Harbor Global at the time of the
    distribution, including the issuance to Pioneer Group stockholders of one
    common share of Harbor Global for every five shares of Pioneer Group common
    stock held on the distribution date, based on the number of shares of
    Pioneer Group common stock outstanding on March 31, 2000, and the
    forgiveness of indebtedness of Harbor Global subsidiaries to Pioneer Group.
    In addition, the number of common shares authorized assumes that Harbor
    Global effects a four-for-one stock split prior to the distribution date.

    Management; and (2) $4,080,000 to fund the repayment of a note payable of
    Forest-Starma prior to the distribution. Also reflects $5,000,000 of cash
    received by Pioneer Goldfields II, which will become a wholly owned
    subsidiary of Harbor Global, in connection with the sale of its Ghanaian
    gold mining operations. Approximately $8,600,000 of the cash contribution is
    reflected in short and long term restricted cash.

(2) Reflects the repayment of $4,960,000 of notes payable to occur prior to the
    distribution. Pioneer Group will contribute $4,080,000 and Harbor Global
    will fund the balance of $880,000.

(3) Harbor Global has consolidated 100% of the net assets of Pioneer Poland
    U.S., L.P. and Pioneer Poland UK, L.P., although Harbor Global's ownership
    interests are 7.2% and 9.2%, respectively. The Polish and Eastern European
    venture capital investments are made through these consolidated partnerships
    which comprise the Pioneer Poland Fund. Harbor Global's interest in the
    Pioneer Poland Fund totals $4,279,000. The difference between the assets
    listed under "Venture Capital Investments" and Harbor Global's interest is
    included under "Minority Interest" and represents the interest of other
    shareholders in the fund.

(4) Harbor Global owns approximately 52% of the equity in the Pioneer First
    Investment Fund. The Pioneer First Investment Fund invests directly in real
    estate, and to a lesser extent, securities of Russian companies. The
    building represents the Meridian Commercial Tower, which comprises a
    significant portion of the assets of Pioneer First investment Fund. The
    long-term investments and approximately $3.4 million in cash comprise the
    balance of the Pioneer First Investment Fund's assets. The 48% interest held
    by the other shareholders of the Pioneer First Investment Fund is recorded
    under Minority Interest and totals $14,010,000.

(5) Reflects a note receivable of Pioneer Goldfields II. Pioneer Goldfields II
    received the note from Ashanti Goldfields Teberebie Limited, in connection
    with the sale of its Ghanaian gold mining operations. The note receivable
    has the following repayment schedule: $2,500,000 in March 2001, $2,500,000
    in March 2002, $3,000,000 in March 2003, $3,750,000 in March 2004 and
    $2,050,000 in March 2005. The note has a net present value of $9,679,000,
    when discounted at a rate of 13%.

(6) Reflects the obligation of Harbor Global under the distribution agreement to
    pay Pioneer Group up to $5 million of the proceeds received by Pioneer
    Goldfields II from Ashanti Goldfields, Teberebie Limited in connection with
    the sale of Pioneer Group's Ghanaian gold mining operations to Ashanti.
    Harbor Global has also assumed approximately $3,600,000 of compensation
    obligations payable to current employees of Pioneer Group or its
    subsidiaries who will become employees of Harbor Global or its subsidiaries
    or Calypso Management.

(7) Reflects the capitalization of Harbor Global at the time of the
    distribution, including the issuance to Pioneer Group stockholders of one
    common share of Harbor Global for every five shares of Pioneer Group common
    stock held on the distribution date, based on the number of shares of
    Pioneer Group common stock outstanding on March 31, 2000, and the
    forgiveness of the indebtedness of Harbor Global subsidiaries to Pioneer
    Group. In addition, the number of common shares authorized assumes that
    Harbor Global effects a four-for-one stock split prior to the distribution
    date.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS

OVERVIEW

     The consolidated financial statements of Harbor Global include its real
estate management and investment management operations in Russia, Polish and
Eastern European venture capital investment and management operations, Polish
and Eastern European real estate management operations, timber harvesting and
sales operations in Russia and gold exploration operations in Russia.

RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997

     Consolidated Operations.  For fiscal year 1999, Harbor Global reported a
net loss from continuing operations of $32.2 million as compared to $45.8
million for fiscal year 1998, reflecting a decrease in net losses of $13.6
million. The decrease was attributable, in large part, to increased
profitability of the Meridian Commercial Towers in 1999 and the adverse
consequences of the Russian financial crisis in 1998. For fiscal year 1999,
losses from discontinued brokerage operations were $1.4 million, and as a result
of a required change in accounting principle, Harbor Global reported the impact
of the write-off of unamortized capitalized start-up costs of $11.5 million.

     For fiscal year 1998, Harbor Global reported a net loss from continuing
operations of $45.8 million as compared to $13.6 million for fiscal year 1997,
reflecting an increase of $32.2 million. The increase was attributable
principally to losses incurred as a result of the Russian financial crisis and a
fire disruption at the timber operation. For fiscal year 1998, Harbor Global
reported losses from discontinued Russian brokerage and banking operations of
$10.7 million as compared to income of $6.0 million in fiscal year 1997,
reflecting a decrease in income of $16.7 million.

     Real Estate Management and Investment Management Operations in
Russia.  Revenues from the Russian real estate management and investment
management operations increased by $1.8 million in 1999 to $10.4 million. This
was principally a result of increased rental revenues at the Meridian Commercial
Tower. The net loss from continuing operations declined by $13.9 million to $1.6
million as certain costs and write-downs incurred in 1998 as a result of the
Russian financial crisis were non-recurring in 1999. The increased profitability
of the Meridian Commercial Tower operations also contributed to the reduction in
the net loss. In 1998, Harbor Global had losses of $6.3 million associated with
cost basis adjustments of certain securities in the Pioneer First Investment
Fund. Additionally, Harbor Global incurred increased bad debt expense and
foreign currency losses in connection with the Russian financial crisis in 1998.
In 1997, the net loss from continuing operations was approximately $3.8 million,
which was related to losses at the management and stockholder services companies
that were partially offset by security gains in the Pioneer First Investment
Fund.

     Losses from the discontinued Russian banking and brokerage operations
totaled approximately $1.4 million and $10.1 million in 1999 and 1998,
respectively. In 1997, the discontinued Russian banking and brokerage operations
reported income of approximately $6.0 million.

     Polish and Eastern European Venture Capital.  Harbor Global had losses from
its Central and Eastern European venture capital operations of $0.8 million in
1999, $0.9 million in 1998 and $0.1 million in 1997. Losses in 1999 reflect a
$0.4 million write off of start up costs associated with the cumulative effect
of a change in accounting principle as well as costs associated with the
development of the venture capital funds. The 1998 losses relate to write downs
to certain portfolio investments.

     Polish and Eastern European Real Estate Management.  Harbor Global's Polish
and Eastern European real estate management operations reported losses of $5.0
million in 1999, $4.9 million in 1998 and $3.4 million in 1997. Most of the
losses were attributable to costs associated with the development of Harbor
Global's Polish and Eastern European real estate investments and related
management operations. The losses increased in 1999 and 1998, over those
incurred in 1997, due to losses recorded in connection with Harbor Global's
investment in the PBO Property Fund in 1998.

<PAGE>   151

     Timber Business.  The results of the timber business are substantially
attributable to the operations of Forest-Starma, which commenced in January
1997. Forest-Starma has developed a modern logging camp, including a harbor,
from which it exports timber to markets in the Pacific Rim. In 1995, Closed
Joint-Stock Company "Amgun-Forest" and Closed Joint-Stock Company "Udinskoye,"
Harbor Global's other Russian timber ventures, each executed a 49 year lease
relating to timber harvesting.

     While Forest-Starma harvests timber and incurs the resulting operating
expenses throughout the year, it ships timber from mid-April through December.
As a result, Forest-Starma has incurred, and expects to continue to incur,
seasonal operating losses from fixed costs in the first quarter of Harbor
Global's fiscal year.

     In 1999, the timber business reported a net loss, prior to the cumulative
effect of a change in accounting principle, of $24.7 million, compared to a net
loss of $21.8 million in 1998. The 1999 net loss includes a reduction in the
carrying value of timber equipment and deferred development costs of
approximately $15.3 million. The $15.3 million adjustment to the cost basis of
the project was recorded in connection with Pioneer Group's realization of
certain US tax benefits. Prior to the cost basis adjustment, the timber
business' net loss was $9.4 million. The reduction in net loss from 1998 to 1999
was principally associated with increased production and prices in 1999. Also,
in 1998 Harbor Global wrote off certain costs incurred in connection with the
Amgun and Udinskoye projects. In 1997, the timber business reported a net loss
of $4.4 million.

     Timber Production and Sales.  Harbor Global had timber shipments of 336,000
cubic meters in 1999, compared to 280,000 cubic meters in 1998 and 194,000 cubic
meters in 1997. Production amounted to 313,000 cubic meters in 1999, compared to
248,000 cubic meters in 1998 and 257,000 cubic meters in 1997. Revenue increased
to $14.4 million in 1999, up from $10.5 million in 1998 and $11.9 million in
1997. The average realized price of timber was $43 per cubic meter in 1999,
compared to $37 in 1998 and $61 in 1997. Forest-Starma expects to produce over
325,000 cubic meters in 2000.

     Production in 1998 was hindered by a fire disruption, which required the
redeployment of logging crews and equipment to contain the fire. There was
damage to approximately 7.8 million cubic meters of standing timber on 76,000
hectares, as well as 5,500 cubic meters of decked logs. Harbor Global does not
believe the fire damage will have a material impact on production over the next
several years. Harbor Global is continuing negotiations with the territorial
government for both replacement and additional cutting rights.

     Cost of Goods Sold.  Forest-Starma values its inventory at the lower of
cost or market under the full absorption accounting method and accordingly,
includes operating costs such as payroll, fuel, spare parts, site related
general and administrative expenses, depreciation and amortization and other
taxes in the cost of goods sold.

     Third-Party Debt.  Forest-Starma had $5.0 million of external debt
outstanding at December 31, 1999. Scheduled principal and interest payments for
2000 are expected to aggregate $1.7 million. Pioneer Group elected to prepay
this third-party financing obligation in the second quarter of 2000 and expects
that it will be repaid in full prior to the distribution.

RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED MARCH 31, 2000 AND 1999

     Consolidated Operations.  For the three months ended March 31, 2000, Harbor
Global reported a net loss from continuing operations of $2.3 million, as
compared to a loss from continuing operations before the change in accounting
principle of $2.1 million for the first quarter of 1999. In the first quarter of
1999, Harbor Global wrote-off $11.5 million of capitalized start-up costs, which
represented the cumulative effect of a change in accounting principle.

Real Estate Management and Investment Management Operations.  Revenues from
Russian real estate management and investment management operations for the
three months ended March 31, 2000, were $1.9 million, as compared to $2.7
million in the first quarter of 1999. The decrease is attributable to a

                                       28
<PAGE>   152

decrease in rental revenues at the Meridian Commercial Tower. During the first
quarter of 2000, the operations reported a net loss from continuing operations
of $0.3 million, a decrease of $1.1 million compared to the corresponding period
in 1999. The decrease was attributable to lower rental revenue at the Meridian
Commercial Towers in 2000 coupled with a non-recurring tax credit recorded in
1999. The decrease in rental revenue was attributable to the restructuring of
certain leases, which increased the term of these leases in exchange for lower
current lease rates. The lease restructuring was designed to maintain the
present value of these leases in view of lower market rates.

Polish and Eastern European Venture Capital.  The Polish and Eastern European
venture capital operations reported income of approximately $0.1 million for the
three months ended March 31, 2000, as compared to a loss of $0.2 million in the
comparable period in 1999. The decrease was largely attributable to operating
cost reductions.

Polish and Eastern European Real Estate Management.  The Company's Polish and
Eastern European real estate management operations reported losses of $0.8
million in the first three months of 2000, compared to losses of $1.3 million in
the same period in 1999. The improvement principally represents management fees
and cost reductions associated with the closing of the Polish Real Estate Fund
in late 1999. Most of the first quarter 2000 losses were attributable to costs
associated with the development of the PBO Property Fund.

Timber Business.  The results of the timber business are substantially
attributable to the operations of Forest-Starma. While Forest-Starma harvests
timber and incurs the resulting operating expenses throughout the year, it
typically ships timber from mid-April through December. As a result, Forest
Starma has incurred, and expects to continue to incur, operating losses from
fixed costs in the first three months of each year. Harbor Global's timber
business reported losses of $1.3 million in the first quarter of 2000 compared
to $1.0 million in the first quarter of 1999. There were no timber shipments in
the three months ended March 31, 2000 nor in the same period of 1999.
Forest-Starma produced approximately 65,200 cubic meters of timber in the first
three months of 2000, as compared to 85,600 cubic meters of timber during the
comparable period in 1999. The reduction in production is attributable to
concerted efforts to realize greater overall value through improvements in grade
quality.

LIQUIDITY AND CAPITAL RESOURCES

     Harbor Global's liquidity needs have historically been met through advances
and capital contributions made by Pioneer Group. Other than the $25 million to
be contributed by Pioneer Group to Harbor Global prior to the distribution,
Harbor Global's cash is generally held by its wholly or majority owned
subsidiaries, and accordingly, it is not available for general corporate
purposes. The $25 million that Pioneer Group will contribute prior to the
distribution will be used to manage the liquidation of Harbor Global's assets
and to discharge certain other obligations. Based upon budget projections,
Harbor Global currently has sufficient cash, without liquidating any of its
assets, to continue to operate its assets for approximately three years. As
such, it may be necessary for Harbor Global to liquidate some of its assets
within three years of the distribution date to continue to operate its remaining
assets pending their liquidation. If Harbor Global is unable to liquidate some
of its assets, it will require additional funding. Harbor Global may not be able
to obtain additional funding, either in the form of additional capital or debt
financing, because of the nature of its operations, namely its intent to hold
its assets for liquidation and its limited duration. In addition, after the
distribution and the merger, Pioneer Group will not own any Harbor Global common
shares, and Pioneer Group and Harbor Global will operate as two wholly
independent companies. As an independent company, Harbor Global will not be able
to obtain additional funding from Pioneer Group.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     Harbor Global monitors its exposure to adverse changes in interest rates,
foreign currency exchange rates and the market price paid for timber.
                                       29
<PAGE>   153

     Harbor Global is exposed to certain changes in foreign currency exchange
rates, primarily as a result of its operations in Russia and Poland. The
functional currency of its Russian operations is the U.S. dollar, while the
functional currency of its Polish operations is the local currency. All of these
operations have some costs denominated in the local currency, which acts as a
natural hedge to the revenues denominated in local currencies.

     In addition, Harbor Global conducts timber operations in Russia. The prices
it receives for its timber products are denominated in U.S. dollars. However, as
most of the timber produced is sold to the Asian markets, the U.S. dollar prices
have been influenced by changes in the foreign currency exchange rates. The
revenues of this business are also subject to changes in the market price paid
for timber.

                                    BUSINESS

     Harbor Global is a Bermuda limited duration company organized in May 2000
to receive various businesses and assets currently owned or operated by Pioneer
Group. Currently, Harbor Global is a wholly owned subsidiary of Pioneer Group.
Following the distribution, all of the outstanding Harbor Global common shares
will be held pro rata by the stockholders of Pioneer Group.

     The assets of Harbor Global consist primarily of the following businesses
and assets, each of which is currently owned or operated by Pioneer Group:

     - real estate management and investment management operations in Russia;

     - Polish and Eastern European venture capital investment and management
       operations;

     - Polish and Eastern European real estate management operations;

     - timber harvesting and sales in Russia;

     - gold exploration operations in Russia;

     - the proceeds from the sale of Pioneer Group's gold mining operations in
       Ghana; and

     - $25 million in cash.

     Harbor Global will seek to liquidate its assets in a timely fashion on
economically advantageous terms. Harbor Global will operate its assets as going
concern businesses until they are liquidated. Harbor Global's memorandum of
association provides that the liquidation of its assets will be completed upon
the earlier of the fifth anniversary of the date of the distribution of Harbor
Global common shares to its shareholders or the distribution by Harbor Global of
all its assets to its shareholders. If Harbor Global has not liquidated all its
assets before the fifth anniversary of the distribution date, the Harbor Global
board of directors, in its discretion, may authorize Harbor Global to continue
to operate its assets for up to three additional one year periods.

     Stephen G. Kasnet will be the President and Chief Executive Officer, and
Donald H. Hunter will be the Chief Operating Officer of Harbor Global. Mr.
Kasnet is currently the President, and Mr. Hunter is currently the Chief
Operating Officer and Senior Vice President of Pioneer Global Investments, a
division of Pioneer Group. As officers of Pioneer Global Investments, Mr. Kasnet
and Mr. Hunter operate substantially all of the businesses that will be
conducted by Harbor Global following the distribution. Prior to the
distribution, Harbor Global will enter into an administration and liquidation
agreement with Calypso Management LLC under which Calypso Management will manage
the liquidation of Harbor Global and operate Harbor Global's assets as going
concern businesses pending their liquidation. Mr. Kasnet is the President and
Chief Executive Officer, and Mr. Hunter is the Chief Operating Officer and Chief
Financial Officer of Calypso Management. See "Certain Relationships and Related
Transactions" in this information statement for more information about the
administration and liquidation agreement.

     Harbor Global does business in countries outside of the United States,
primarily in Russia and Poland. In the year ended December 31, 1999, nearly all
of Harbor Global's revenues were derived from operations outside of the United
States. Harbor Global's businesses and assets are described below, together with
the principal strategies that Harbor Global currently intends to employ to sell
or liquidate the assets.

     Harbor Global intends to change the names of its subsidiaries that
currently contain the "Pioneer" name before the distribution. Accordingly, the
names of some of the Harbor Global subsidiaries used in this information
statement will be changed. For more information see "The Distribution -- The
Distribution Agreement -- Names" in this information statement.

RUSSIAN REAL ESTATE AND INVESTMENT MANAGEMENT

     Ownership Structure.  Harbor Global's Russian real estate management and
investment management operations are consolidated under its wholly owned
Delaware subsidiary, Pioneer Omega, Inc. Pioneer
                                       31
<PAGE>   155

Omega owns an approximately 82% interest in Pioneer First Russia, Inc., a
Delaware corporation, and the International Finance Corporation, a member of the
World Bank Group, owns an approximately 18% interest in Pioneer First Russia.
Pioneer First Russia in turn operates through two wholly owned subsidiaries,
Closed Joint-Stock Company "Pioneer First," an investment management company
(JSC Pioneer First), and Closed Joint-Stock Company "Pioneer Services," a
stockholder services company (JSC Pioneer Services). Both JSC Pioneer First and
JSC Pioneer Services are Russian joint stock companies.

     In addition, Pioneer Omega, through its two wholly owned Delaware
subsidiaries, Lucinia, Inc. and Theta Enterprises, Inc., holds an approximately
52% interest in Pioneer First Investment Fund, a Russian joint stock company
managed by JSC Pioneer First.

     Currently, approximately two million Russian stockholders hold the
remaining approximately 48% interest in Pioneer First Investment Fund.

     Pioneer First Investment Fund.  Pioneer First Investment Fund invests
directly in real estate and, to a lesser extent, securities of Russian
companies. A significant portion of the assets of Pioneer First Investment Fund
consists of its ownership of the Meridian Commercial Tower, an 18-story, 22,600
square meter office building in Moscow, Russia. The Meridian Commercial Tower is
primarily occupied by American and European corporate tenants and is managed by
PREA, LLC (formerly Pioneer Real Estate Advisors, Inc.), Harbor Global's real
estate management subsidiary. Pioneer First Investment Fund has agreed to pay
PREA a property management fee of 5% of gross revenues less any value added
taxes or similar taxes. In 1999, Pioneer First Investment Fund paid PREA
approximately $433,000 in property management fees.

     PREA leases the Meridian Commercial Tower from Pioneer First Investment
Fund under a master lease agreement and, in turn, subleases the premises to
tenants. The initial term of the master lease agreement between Pioneer First
Investment Fund and PREA will expire in July 2001, but may be extended at the
option of PREA for two additional five-year periods. Under the master lease
agreement PREA pays Pioneer First Investment Fund an amount equal to gross
revenues less building operating expenses, the PREA property management fee
described above and any value added taxes or similar taxes. In 1999, Meridian
Commercial Tower net lease revenues were approximately $8.6 million and
accounted for approximately 90% of the revenues of Pioneer First Investment
Fund.

     The remaining assets of Pioneer First Investment Fund primarily consist of
real estate related securities, including a 25% interest in the Cosmos Hotel,
located in Moscow, Russia, and securities in Russian companies, some of which
are illiquid.

     JSC Pioneer First.  Under a management agreement between JSC Pioneer First
and Pioneer First Investment Fund, JSC Pioneer First has agreed to provide
management services to Pioneer First Investment Fund for an annual fee of 5% of
gross assets less any value added taxes or similar taxes. In 1999, Pioneer First
Investment Fund paid JSC Pioneer First an aggregate management fee of
approximately $3.1 million.

     JSC Pioneer First also serves as an investment manager to two Russian
open-end unit investment funds having an aggregate market value of $1.8 million
at March 31, 2000. Pioneer First Unit Investment Fund was organized by Pioneer
Group in 1996 and is one of Russia's first open-end unit investment funds.
Pioneer First Unit Investment Fund invests primarily in Russian government
bonds. Pioneer First Liquid Shares was organized by Pioneer Group in 1997 and
invests primarily in Russian securities and government bonds.

     As compensation for its investment management services to Pioneer First
Unit Investment Fund and Pioneer First Liquid Shares, JSC Pioneer First receives
annual management fees equal to three percent of the annual net asset value of
the Pioneer First Unit Investment Fund and three and one-half percent of the
annual net asset value of Pioneer First Liquid Shares. In 1999, Pioneer First
Unit Investment Fund and Pioneer First Liquid Shares paid JSC Pioneer First
aggregate management fees of approximately $30,000.
                                       32
<PAGE>   156

     JSC Pioneer Services.  Through December 1999, JSC Pioneer Services was the
transfer agent to Pioneer First Investment Fund and Pioneer First Unit
Investment Fund. JSC Pioneer Services maintained the funds' shareholder
registers and provided customer service and technical support to the funds. As a
result of new legislation enacted by the Russian Federal Securities Commission,
Russian funds are currently prohibited from using a registrar which is directly
related to the fund's management company and requires a Russian registrar to
have at least five stockholders and maintain at least 50 registers. Because JSC
Pioneer Services does not meet these three Russian registrar requirements, as of
December 23, 1999, JSC Pioneer Services was no longer licensed to act as a
registrar within the Russian Federation.

     As a result, JSC Pioneer Services entered into a service contract with the
National Registry Company (NRC) whereby JSC Pioneer Services agreed to pay NRC
an annual fee of $50,200 for the use of its registrar license, and five
employees of JSC Pioneer Services became employed by NRC to service Pioneer
First Investment Fund and Pioneer First Unit Investment Fund. The five JSC
Pioneer Services employees are compensated by JSC Pioneer Services.

     JSC Pioneer Services' operations are supported solely by a transfer agent
fee from Pioneer First Investment Fund. In 1999, Pioneer First Investment Fund
paid JSC Pioneer Services a transfer agent fee of approximately $950,000.

     In 1999, 1998 and 1997, Harbor Global's Russian real estate management and
investment management operations had revenues and net income (loss) from
continuing operations as shown in the table below:

     Minority Interest in Pioneer First Russia.  In connection with the
investment by the International Finance Corporation in Pioneer First Russia,
International Finance Corporation, Pioneer Omega, Inc. and Pioneer First Russia
entered into a stockholders agreement and a put and call agreement. Under the
stockholders agreement, Pioneer Omega may not transfer or pledge its shares of
Pioneer First Russia common stock without the consent of the International
Finance Corporation if, as a result of the transfer or pledge, Pioneer Omega
would cease to own at least 51% of the outstanding shares of Pioneer First
Russia. In addition, under the stockholders agreement, as long as the
International Finance Corporation is a stockholder of Pioneer First Russia, the
International Finance Corporation is entitled to nominate one person to the
Pioneer First Russia board of directors. The approval of the International
Finance Corporation nominated director is required to take the actions that may
materially affect the business of Pioneer First Russia.

     Under the put and call agreement, from October 2000 to October 2004, upon
written notice to Pioneer Omega, the International Finance Corporation will have
the right to cause Pioneer Omega to purchase all of its shares of Pioneer First
Russia common stock. From October 2004 to October 2006, upon written notice to
the International Finance Corporation, Pioneer Omega will have the right to buy
all of the International Finance Corporation's shares of Pioneer First Russia
common stock. In each case, the purchase price to be paid by Pioneer Omega is
equal to the greater of the International Finance Corporation's pro rata share,
calculated on a fully diluted basis, of Pioneer First Russia's net asset value
on a specified date not more than 30 or less than 60 days from the date of the
notice or 12 times the three year average of the product of net income divided
by the weighted average of the number of shares outstanding during such period
times the weighted average of shares held by the International Finance
Corporation during such period.

     Under the put and call agreement, if the International Finance Corporation
proposes to transfer any of its shares to any party, Pioneer Omega has a right
of first refusal to purchase the shares proposed to be transferred. In addition,
if Pioneer First Russia proposes to issue any of its common stock, or a security

                                       33
<PAGE>   157

convertible into shares of its common stock, the International Finance
Corporation has a preemptive right to purchase its pro rata portion of the
securities to be issued.

     Insurance.  Harbor Global maintains Overseas Private Insurance Corporation
(OPIC) political risk insurance in an amount that would protect up to 90% of its
equity investment in the Pioneer First Investment Fund and loans as reduced by
cumulative losses.

     Asset Realization Strategy.  JSC Pioneer First is seeking to increase the
value of the Pioneer First Investment Fund through a process of restructuring
the Pioneer First Investment Fund portfolio by:

     - selling securities which are considered illiquid;

     - increasing the value of its real estate holdings through the
       redevelopment of the Cosmos Hotel;

     - investing in real estate and in more liquid securities;

     - improving the value of its investments in portfolio companies through
       active board representation; and

     - exploring alternatives to reduce the number of Pioneer First Investment
       Fund stockholders.

     PREA is managing, on behalf of Pioneer First Investment Fund, the
redevelopment of the Cosmos Hotel, a moderately priced hotel with approximately
1,770 rooms. PREA currently plans to convert a portion of the hotel into
commercial office space and corporate apartments and upgrade the remaining hotel
facilities. Harbor Global believes that restructuring the Pioneer First
Investment Fund portfolio as described above will maximize the value of Pioneer
First Investment Fund in a sale.

     In addition, JSC Pioneer First is seeking to increase the asset level of
the two Russian unit investment funds it manages. Harbor Global believes that by
increasing JSC Pioneer First's assets under management, it will be more likely
to realize economies of scale and to attract additional institutional investors,
which Harbor Global believes will, in turn, maximize the value of Pioneer First
Russia in a sale.

     Competition.  JSC Pioneer First is seeking to increase its assets under
management by competing for institutional investors for the two Russian unit
investment funds it manages. However, many of its competitors have substantially
greater resources to attract institutional investors.

     Employees.  At May 31, 2000, Pioneer First Russia and its subsidiaries
together with Pioneer First Investment Fund employed 44 persons.

POLISH AND EASTERN EUROPEAN REAL ESTATE

     Ownership Structure.  Harbor Global's Polish and Eastern European real
estate investment and management operations are conducted by PREA, a wholly
owned Delaware subsidiary of Harbor Global, and its subsidiaries. PREA provides
real estate investment opportunities in Poland and Eastern Europe to
institutional investors through two pooled investment funds, the Polish Real
Estate Fund and the PBO Property Fund, LLC. PREA is based in Boston and conducts
its operations in Russia through a representative office in Moscow, and in
Poland through a wholly owned subsidiary, Pioneer Real Estate Advisors Poland
Sp. z o.o., a Polish limited liability company.

     Polish Real Estate Fund.  In October 1999, PREA established the Polish Real
Estate Fund, a Polish real property fund with committed capital of $33.5 million
created to invest in a diversified portfolio of commercial real estate in
Poland, including office space, warehouse/distribution centers and retail
centers. PREA has committed to invest $5.7 million and other Polish and
non-United States institutional investors have committed to invest $27.8
million. As of May 31, 2000, PREA had invested approximately $285,000 in the
Polish Real Estate Fund and the other investors had invested a total of $1.57
million. Currently, none of the Polish Real Estate Fund's committed capital has
been invested. After October 20, 2001, the Polish Real Estate Fund may be
liquidated by a vote of stockholders representing three-fourths of the fund's
capital if less than one-third of the fund's capital is invested or committed to
be invested as of

                                       34
<PAGE>   158

October 20, 2001, or if less than two-thirds of the fund's capital is invested
or committed to be invested as of October 21, 2002.

     Pioneer Real Estate Advisors Poland has agreed to act as the investment
advisor of the Polish Real Estate Fund for an annual base advisory fee equal to
2% of the Polish Real Estate Fund's net capital and after October 2002, equal to
1 1/2% of net capital, as defined in the investment advisory services agreement.
In addition, after the Polish Real Estate Fund stockholders have received a
return of their original capital contributions plus a 10% cumulative annual
return, Pioneer Real Estate Advisors Poland is entitled to an additional annual
incentive advisory fee. In 1999, the Polish Real Estate Fund paid Pioneer Real
Estate Advisors Poland approximately $110,000 in advisory fees.

     Under its investment advisory services agreement with Pioneer Real Estate
Advisors Poland, the Polish Real Estate Fund may terminate the agreement upon
the written resolution of its stockholders holding two-thirds of its voting
shares if Pioneer Real Estate Advisors Poland ceases to be directly or
indirectly controlled by Pioneer Group. As a result of the distribution by
Pioneer Group of Harbor Global shares of common shares to Pioneer Group
stockholders, the Polish Real Estate Fund stockholders will have the right to
terminate the advisory services agreement because Pioneer Group will cease to
directly or indirectly control Pioneer Real Estate Advisors Poland. PREA is
currently seeking a waiver of the right to terminate the advisory services
agreement from the Polish Real Estate Fund stockholders and expects to obtain
the waiver prior to the distribution date. If this waiver is not obtained, the
value of Harbor Global's carried interest in the Polish Real Estate Fund and any
potential benefit derived from this carried interest to Harbor Global may be
materially adversely affected, which in turn may adversely affect the results of
operations and financial condition of Harbor Global's Polish and Eastern
European real estate management business.

     PREA also provides advisory services to third parties. The scope of its
advisory services includes property management, facilities management,
development management, feasibility and valuation analysis, fund management and
corporate advisory services.

     PBO Property Fund.  In May 1998, PREA and Banc One Capital Holdings
Corporation, established the PBO Property Fund, LLC, a pooled investment fund
sponsored by the Overseas Private Investment Corporation (OPIC). PBO Property
Capital, LLC, a 99% owned Delaware subsidiary of PREA, manages the PBO Property
Fund. The PBO Property Fund will consider investing in a broad array of
commercial property projects in Central and Eastern Europe and the independent
states of the former Soviet Union, including:

     - warehousing/distribution centers;

     - office buildings;

     - light assembly/manufacturing facilities;

     - big-box, single tenant retail space; and

     - business hotels with master lease support.

     The PBO Property Fund is designed to be funded with up to $80 million of
equity from institutional investors and up to $160 million of debt guaranteed by
OPIC. PREA is actively seeking, directly and through third parties, capital
commitments for the PBO Property Fund. As of June 16, 2000, PREA, through PBO
Property Capital, had invested approximately $167,300 in the PBO Property Fund.
Additionally, Pioneer Group has invested approximately $1.5 million in the PBO
Property Fund.

     Currently, each of PREA, together with PBO Property Capital, and Banc One
Capital Holdings holds approximately 50% of the membership interests in the PBO
Property Fund. Under the PBO Property Fund limited liability company agreement,
members of the PBO Property Fund are entitled to receive cash distributions
first equal to their initial capital contributions and then in preferential
amounts as specified in the PBO Property Fund limited liability company
agreement. Before paying cash distributions to its members, the PBO Property
Fund must pay its expenses, including the payment of an asset management

                                       35
<PAGE>   159

fee to PBO Property Capital and the payment of amounts due to OPIC in connection
with the financing agreement between OPIC and the PBO Property Fund.

     PBO Property Capital, as the manager of the PBO Property Fund, is entitled
to receive an annual asset management fee equal to 2% of the aggregate amount of
committed capital. In 1999, the PBO Property Fund paid PBO Property Capital an
aggregate management fee of $825,000.

     Asset Realization Strategy.  PREA is currently negotiating with new
American and Polish investors in an effort to increase the capital commitments
in the Polish Real Estate Fund to approximately $55 million. PREA will continue
to seek institutional investors for its Polish Real Estate Fund and PBO Property
Fund to increase their committed capital and, in turn, maximize their value in a
sale.

     Competition.  PREA is actively competing for institutional investors for
its Polish Real Estate Fund and PBO Property Fund. However, PREA must compete
with a large number of real estate firms, many of which have substantially more
resources than those available to PREA.

     Employees.  At May 31, 2000, PREA and its subsidiaries had 36 employees,
including two expatriate employees provided by PIOGlobal Corporation, a Delaware
corporation and wholly owned subsidiary of Harbor Global, and 12 employees of
the Meridian Commercial Tower.

RUSSIAN TIMBER

     Ownership Structure.  Harbor Global's Russian timber operations are
conducted through its indirect subsidiaries Closed Joint-Stock Company
"Forest-Starma," Closed Joint-Stock Company "Udinskoye" and Closed Joint-Stock
Company "Amgun-Forest". These three companies will be consolidated under Pioneer
Forest, LLC, a wholly owned Delaware subsidiary of Harbor Global. Udinskoye is a
wholly owned subsidiary, and Amgun-Forest is an approximately 99.5% owned
subsidiary of Forest-Starma. Of the three companies, Forest-Starma is the only
company currently engaged in timber operations. Forest-Starma, which is located
on Siziman Bay in the Vanino district of the Khabarovsk Territory of the Russian
Far East, owns and operates a modern logging camp, including a harbor facility,
from which it exports timber to markets in the Pacific Rim, primarily Japan and
South Korea.

     Leasehold and Cutting Rights.  Forest-Starma, Amgun-Forest and Udinskoye
have each been granted long-term leases that provide significant leasehold
acreage and annual cutting rights. In the aggregate, the three subsidiaries have
been granted long-term leasehold rights comprising 1,076,500 hectares
(approximately 2.7 million acres), with annual cutting rights of approximately
1.2 million cubic meters. Each of the leases has a 49-year term with expiration
dates ranging from 2046 to 2047. The current leasehold rights of each of the
subsidiaries appear in the table below:

<TABLE>

Annual Cutting Rights (m(3))...................     555,000           350,000      300,000
</TABLE>

     Currently, the local timber authorities are reviewing the cutting rights
for Forest-Starma and Udinskoye. Because of losses due to natural drying and
other causes, Harbor Global expects that its annual cutting rights in those
areas where it currently has leasehold rights will be reduced. However, Harbor
Global is currently negotiating with the territorial government to obtain
replacement cutting rights in the surrounding area.

     In addition, Harbor Global has commenced the process of unifying the
Udinskoye and Forest-Starma leaseholds. This process requires that Udinskoye
tender its leasehold rights back to the Russian state in order for the Russian
state to tender these rights to Forest-Starma.

     Timber Operations.  Forest-Starma seeks to harvest timber according to
international sustainable development standards using advanced planning and
implementation of the management practices as defined in the United States
Forest Service stewardship guidelines and the United Nations Conference on
Environment and Development principles. Production crews consisting, in the
aggregate, of four harvesters, eight skidders, and five processors form the
nucleus of the logging operation. The harvesters cut the trees, which are then
skidded to processors that delimb the timber. The logs are hauled on company
constructed roads by log trucks approximately 50 kilometers to a lower landing
log yard for sorting and scaling prior to shipment. The lower landing is
equipped with log loaders and other equipment necessary for maintaining the log
yard and delivering sorted logs to the self-constructed harbor for shipment.
Sorted logs are delivered to the Siziman Bay harbor based upon a manifest
received from Forest-Starma's marketing and sales agent, Rayonier, Inc. The logs
are then delivered to the dock and placed on ships by crane. Forest-Starma has
constructed and maintains a self-contained camp with living quarters for between
250 and 300 workers, a modern maintenance and parts facility, on-site offices
and sophisticated communications equipment.

                                       37
<PAGE>   161

     During the period between January and mid-April, the Siziman Bay harbor
typically is frozen, which prevents the delivery of harvested timber. In January
2000, Forest-Starma entered into an agreement with Rayonier, Inc. to receive
prepayment for timber production during this period. This arrangement allows
Forest-Starma to cover ongoing expenditures prior to commencement of the
shipping season. Forest-Starma has already shipped sufficient amounts of logs to
Rayonier to repay all advances made to Forest-Starma under this agreement.

     In 1999, Forest-Starma shipped 56% of its timber to ten customers in South
Korea, 35% of its timber to six customers in Japan and 9% of its timber to three
customers in China. The following chart shows Forest-Starma's total production
and shipments of timber during the last three years.

RUSSIAN GOLD EXPLORATION

     Ownership Structure.  Harbor Global's Russian gold exploration operations
are conducted through its indirect majority owned Russian subsidiary, Closed
Joint-Stock Company "Tas-Yurjah" Mining Company. Harbor Far East Exploration,
LLC, a wholly owned subsidiary of Harbor Global, will own a 94.5% direct
interest and a 0.6% indirect interest in Tas-Yurjah.

     Gold Exploration.  Tas-Yurjah conducts the exploration of potential gold
mining properties over concession areas in the Ayano-Maysky district of the
Khabarovsk Territory. Tas-Yurjah has secured four licenses which permit it to
conduct geological exploration activities over aggregate concession areas
totaling 909.7 square kilometers. Two of these licenses also allow for mining in
their respective concession areas and require that production commence at
specified levels in 2001 to maintain their validity. In addition, Tas-Yurjah
will forfeit its exploration and mining licenses if it fails to comply with
other covenants, which include:

     - meeting Russian environmental standards;

     - meeting Russian health and safety standards for its employees;

     - taking part in the social and economic development of the Ayano-Maysky
       district of the Khabarovsk Territory; and

     - preferential hiring of the Ayano-Maysky population.

                                       38
<PAGE>   162

Tas-Yurjah has completed a number of feasibility studies on the Red Zone and has
conducted preliminary studies of the mineral deposits in the Malyutka Zone but
has not developed any part of the concession area for extraction operations. In
addition, Tas-Yurjah is presently exploring other zones in the concession area.

     As of December 31, 1999, Pioneer Group had spent a total of approximately
$6.4 million for exploration work related to Tas-Yurjah, $1.0 million of which
was spent in 1999.

     Asset Realization Strategy.  Harbor Global is actively exploring strategic
alternatives with respect to Tas-Yurjah, including the sale of its interest in
Tas-Yurjah.

     Employees.  At May 31, 2000, Tas-Yurjah had 38 employees, including 26
seasonal employees.

OTHER ASSETS

     Cash.  Under the contribution agreement, prior to the distribution date,
Pioneer Group will contribute $25 million to Harbor Global. Harbor Global
believes that this cash contribution will be sufficient to pay the expenses,
capital commitments and liabilities, if any, associated with the operation of
its assets for a period of approximately three years.

     Ashanti Proceeds.  In May 2000, Pioneer Goldfields II Limited, a wholly
owned subsidiary of Harbor Global, sold its gold mining operations in Ghana to
Ashanti Goldfields Teberebie Limited for an $18.8 million base purchase price
plus additional payments of up to $5 million contingent upon the market price of
gold and productivity of the Ghanaian goldmine. On June 19, 2000, $5 million of
the base purchase price was paid to Pioneer Goldfields II in cash and $13.8
million of the base purchase price was paid in the form of a promissory note.
Under the promissory note, Ashanti is obligated to pay the purchase price over
five years, with principal amounts of between $2.0 million and $3.75 million due
annually, as specified in the purchase agreement.

     In connection with the sale to Ashanti, each of Pioneer Goldfields II and
Pioneer Group agreed to indemnify Ashanti for the breach of any representation
or warranty of Pioneer Goldfields II contained in the purchase agreement for an
amount not to exceed the total purchase price paid by Ashanti to Pioneer
Goldfields II under the purchase agreement. The representations and warranties
contained in the purchase agreement, other than those relating to tax and
environmental issues, survive until June 19, 2002. The tax and environmental
representations and warranties survive the closing of the purchase agreement
until June 19, 2005. Under the distribution agreement, Harbor Global has agreed
to reimburse Pioneer Group for any liability it incurs in connection with any
claim brought by Ashanti for indemnification under the purchase agreement. See
"The Distribution -- The Distribution Agreement" in this information statement
for more information about Harbor Global's obligation to indemnify Pioneer
Group.

     In addition, under the distribution agreement, Harbor Global has agreed
that promptly after the fifth anniversary of the closing of the purchase
agreement it will pay to Pioneer Group the lesser of $5 million or the proceeds
received by Pioneer Goldfields II from Ashanti under the purchase agreement less
any indemnification claims paid under the purchase agreement. If any
indemnification claim under the purchase agreement is pending on June 19, 2005,
Harbor Global will pay the appropriate amount described above promptly upon
resolution of the pending claim or claims.

     Metals.  Harbor Global will own a 25% interest in Pioneer Metals and
Technology. Pioneer Metals and Technology is engaged in the production and sale

 *  Denotes ownership of less than 1% of outstanding shares of either Pioneer
    Group common stock or Harbor Global common shares, as applicable.

 +  Denotes a director or executive officer of Harbor Global.

(1) The inclusion of shares of common stock listed as beneficially owned does
    not constitute an admission of beneficial ownership of those shares.

(2) Includes options that will be exercisable on the distribution date due to
    the full acceleration of vesting of these options in connection with the
    merger.

(3) For purposes of this table, the percentage of outstanding shares of common
    stock is adjusted for each director and executive officer to include the
    number of shares of Pioneer Group common stock into which the listed options
    held by such director or executive officer will be exercisable.

(4) The Harbor Global pro forma ownership calculations assume that directors or
    officers will not exercise any of their currently exercisable options prior
    to closing the merger, and therefore, that these persons will not receive
    Harbor Global common shares for the shares of Pioneer Group common stock
    underlying their options.

(5) Includes 1,167,410 shares of Pioneer Group common stock held by family
    trusts of which Mr. Cogan is the sole trustee and with respect to which he
    has sole voting and investment power; an aggregate of 74,340 shares of
    Pioneer Group common stock held in trusts with respect to which Mr. Cogan
    may be deemed to be a beneficial owner by reason of his position as a
    trustee and/or his interests as beneficiary, over which shares Mr. Cogan
    exercises shared voting and investment power; and 35,958 shares of Pioneer
    Group common stock held for the benefit of Mr. Cogan in Pioneer Group's
    deferred compensation plan, over which shares Mr. Cogan exercises no voting
    power and sole investment power.

(6) Consists of shares of Pioneer Group common stock held by a variety of
    investment advisory clients, over which shares Southeastern Asset
    Management, Inc. exercises sole, shared or no voting authority and exercises
    sole or shared investment power. This information is based solely on
    information provided by Southeastern Asset Management, Inc. in Amendment No.
    1 to Schedule 13G dated June 7, 2000, with respect to shares held on May 31,
    2000.

(7) Consists of shares of Pioneer Group common stock held by a variety of
    investment advisory and investment company clients, over which shares
    Gabelli Funds, Inc., Gabelli Asset Management, Inc. or one of their
    affiliates exercises sole voting authority and sole investment power. This
    information is based solely on information provided by Gabelli Funds, Inc.
    in Amendment No. 13 to Schedule 13D dated June 16, 2000, with respect to
    shares held on June 14, 2000.

(8) Of the shares beneficially owned by the directors and executive officers of
    Pioneer Group as a group, an aggregate of 4,495,875 shares are subject to a
    voting agreement that Mr. Cogan, Mr. Tripple, Robert Nault and Eric Reckard
    entered into in connection with the merger agreement and pursuant to which
    each agreed to vote his shares in favor of the merger agreement and the
    merger.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     The businesses that Harbor Global will conduct have engaged in transactions
with Pioneer Group in the past, some of which included various types of
financial support by Pioneer Group. These transactions were often on terms more
favorable to the businesses conducted by Harbor Global than would otherwise have
been attainable in similar transactions with unaffiliated third parties.
Following the distribution, Harbor Global will continue to have a relationship
with Pioneer Group only as a result of the distribution agreement and the tax
separation agreement entered into in connection with the distribution. The
transactions contemplated between Harbor Global and Pioneer Group by the
distribution agreement and the tax separation agreement are described in "The
Distribution" in this information statement. In addition, Harbor Global and
Pioneer Group may enter into an agreement under which Pioneer Group may agree to
provide corporate administrative, information and technology and other support
to Harbor Global for a limited transition period.

     Other than as contemplated by the distribution agreement and tax separation
agreement, following the distribution, Harbor Global and Pioneer Group will not
have any material contractual or other material relationships with each other,
and transactions between Harbor Global and Pioneer Group will be conducted on an
arms-length basis.

     Harbor Global is expected to enter into an administration and liquidation
agreement with Calypso Management LLC pursuant to which Calypso Management will,
at the direction of the Harbor Global board of directors, manage the liquidation
of Harbor Global and operate Harbor Global's assets pending their liquidation.
The administration and liquidation agreement is expected to have a term ending
upon the liquidation of Harbor Global. The agreement is expected to provide that
Harbor Global will pay the operating expenses of Calypso Management incurred in
connection with the provision of services to Harbor Global. These operating
expenses are expected to include annual salaries for Mr. Kasnet and Mr. Hunter
of $325,000 and $250,000, respectively, plus annual bonuses of up to 100% of
such base salary, depending upon the achievement of performance goals to be
established by the Harbor Global board of directors. Calypso Management will
provide the services of Mr. Kasnet and Mr. Hunter and other employees to act as
officers and employees of Harbor Global. As compensation for its provision of
services to Harbor Global, Calypso Management is expected to receive a portion
of the net proceeds distributed from the liquidation of Harbor Global's assets,
generally according to the following schedule:

     - with respect to the first $36 million in net proceeds available for
       distribution, Calypso Management shall receive a payment equal to 10% of
       such net proceeds;

     - with respect to the next $72 million in net proceeds available for
       distribution, Calypso Management shall receive a payment equal to 7.5% of
       such net proceeds; and

     - with respect to any additional net proceeds, Calypso Management shall
       receive a payment equal to 10% of such net proceeds.

Net proceeds will not include any unexpended portion of the $25 million
contributed by Pioneer Group to Harbor Global. The proceeds received by Pioneer
Goldfields II in connection with the sale of its Ghanaian gold mine to Ashanti
will not be subject to the preceding schedule. Instead, Calypso Management will
receive only 5% of the Ashanti proceeds that are distributed, if any.

     In addition, Harbor Global will pay Mr. Kasnet a signing and retention
bonus of $1.8 million if he remains employed by Calypso Management and Calypso
Management continues to provide services to Harbor Global on the second
anniversary of the distribution date, or if Harbor Global terminates his
employment without cause prior to the second anniversary of the distribution
date.

     Following the first two years of the term of the administration and
liquidation agreement, Calypso Management may terminate the agreement upon 120
days notice to Harbor Global. Harbor Global may terminate the agreement in the
event of Mr. Kasnet's death or disability, or upon an uncured failure by Calypso
Management to follow a reasonable direction of the Harbor Global board of
directors. Generally, Calypso Management will not be entitled to the payments
described above following a termination of the agreement. As part of the
administration and liquidation agreement, Calypso Management will agree to
customary confidentiality and noncompetition covenants with respect to Harbor
Global.

                   DESCRIPTION OF HARBOR GLOBAL SHARE CAPITAL

     Your rights as a holder of Harbor Global common shares will be governed by
Bermuda law and Harbor Global's memorandum of association and bye-laws. The
following is a summary of certain provisions of Bermuda law and Harbor Global's
memorandum of association and bye-laws. This summary may not contain all of the
information that may be important to you. You should carefully read the
memorandum of association and bye-laws of Harbor Global, copies of which have
been filed with the Securities and Exchange Commission as exhibits to Harbor
Global's registration statement on Form 10, of which this information statement
is a part. For information on how you may obtain a copy of Harbor Global's
memorandum of association and bye-laws, see "Where You Can Find Additional
Information" in this information statement.

     Under Harbor Global's memorandum of association, Harbor Global's authorized
share capital consists of 12,000,000 common shares, par value $.01 per share,
and 1,000,000 preferred shares, par value $.01 per share. Pioneer Group
currently owns 1,200,000 Harbor Global common shares. No Harbor Global preferred
shares have been issued. Prior to the distribution, Harbor Global will effect a
four-for-one stock split of its common shares and Pioneer Group will purchase
enough additional Harbor Global common shares so that it may distribute one
Harbor Global common share for every five shares of Pioneer Group common stock
held by you immediately before closing the merger. After giving effect to the
four-for-one stock split, Harbor Global's authorized common share capital will
consist of 48,000,000 common shares, par value $.0025, of which Pioneer Group
will own 4,800,000 shares. Based on the number of shares of Pioneer Group common
stock outstanding on June 22, 2000, immediately following the distribution
approximately 5,371,428 million Harbor Global common shares will be outstanding.
This amount may increase prior to the distribution date due to the issuance of
shares of Pioneer Group common stock upon the exercise of outstanding options.
All of the Harbor Global common shares to be distributed to you in the
distribution will be fully paid and nonassessable.

COMMON SHARES

     Each outstanding Harbor Global common share is entitled to one vote on all
matters submitted to a vote of Harbor Global shareholders, including the
election of directors. There are no cumulative voting rights. As a holder of
Harbor Global common shares you are entitled to receive dividends if, when and
as declared by the board of directors out of assets legally available for the
payment of dividends. In the event of a liquidation, dissolution, or winding up
of Harbor Global, Harbor Global's assets will be distributed pro rata among the
holders of Harbor Global common shares after satisfaction in full of its debts
and liabilities. The holders of Harbor Global common shares have no preemptive,
redemption, conversion or subscription rights and there are no sinking fund
provisions. The rights, powers, preferences and privileges of holders of Harbor
Global common shares are subject to, and may be impaired by, the rights of any
preferred shares that Harbor Global may designate and issue in the future.

PREFERRED SHARES

     Under Harbor Global's bye-laws, the Harbor Global board of directors is
authorized, without further shareholder approval, to issue an aggregate of
1,000,000 preferred shares in one or more classes or series and to fix the
voting powers, if any, and the preferences, privileges and restrictions of the
preferred shares, including dividend rights, dividend rates, conversion rights,
terms of redemption, redemption prices and liquidation preferences of any class
or series of preferred shares. Although the board of directors does not
presently intend to do so, it could issue preferred shares with rights that
could adversely affect the voting power and other rights of holders of Harbor
Global common shares without obtaining the approval of its shareholders. In
addition, the issuance of preferred shares could delay or prevent a change in
control of Harbor Global without further action by its shareholders.

BERMUDA LAW AND ADDITIONAL PROVISIONS OF HARBOR GLOBAL'S MEMORANDUM OF
ASSOCIATION AND BYE-LAWS

     Meetings of Shareholders.  Under Bermuda law, a company is required to
convene at least one general shareholders' meeting per calendar year. Bermuda
law provides that a special general meeting must be convened by the board of
directors upon the request of shareholders holding not less than 10% of the
paid-up capital of the company having the right to vote. Bermuda law also
requires that shareholders be given at least five days' advance notice of a
general meeting. Harbor Global's bye-laws provide that the accidental omission
of notice to any person does not invalidate the proceedings at the meeting.
Harbor Global's bye-laws require that at least five days' advance notice of an
annual general meeting or a special general meeting be given to each
shareholder.

     Shareholder Action.  Under Bermuda law, the number of shareholders
constituting a quorum at any general meeting of shareholders is determined by
the bye-laws of the company. Harbor Global's bye-laws provide that a minimum of
two persons present in person and representing in person or by proxy in excess
of 50% of the total issued voting shares of Harbor Global constitutes a quorum.
Any action to be taken by Harbor Global shareholders at a general meeting or
special general meeting may be taken by unanimous written consent of the
shareholders without a meeting and without previous notice being given.

     Election or Removal of Directors.  Under Harbor Global's bye-laws, the
initial directors are elected for a term expiring at the annual general meeting
immediately following the fifth anniversary of the date of the distribution of
Harbor Global common shares to Pioneer Group stockholders or until their
successors are elected or appointed, unless they resign or are earlier removed.
Subsequent directors are elected at the annual general meeting for a term of
three years or until their successors are elected or appointed, unless they
resign or are earlier removed.

     Harbor Global's bye-laws provide that a director may only be removed for
cause at a special general meeting of shareholders specifically called for that
purpose. The director whose removal is sought must be served with at least 14
days' notice of the meeting, and the director has a right to be heard at the
meeting. Any vacancy created by the removal of a director at a special general
meeting may be filled by the shareholders or by the board.

     Advance Notice Requirements for Shareholder Nominations and
Proposals.  Under Harbor Global's bye-laws, a shareholder seeking (1) to bring
business before an annual general meeting or special general meeting or (2) to
nominate candidates for election as directors must provide Harbor Global with
timely written notice of the nomination or proposal. To be timely, notice in
connection with a special meeting must be received by Harbor Global not less
than 60 nor more than 90 days before the meeting, and notice before an annual
general meeting must be received by Harbor Global not less than 60 nor more than
90 days before the anniversary date of the prior year's annual general meeting,
excluding, in each case, the meeting date and the date the notice is received by
Harbor Global. The notice must contain the name and business background of the
person to be nominated as director and all material information on any proposal
and any additional information the board of directors may specify from time to
time.

     Shareholder Proposals.  Under The Companies Act 1981 of Bermuda, Harbor
Global must circulate notice of a properly supported shareholder requisition
proposing a resolution to be passed on at the next annual general meeting of the
company, together with a statement of up to 1,000 words in response to the
proposed resolution. The resolution must be supported by the lesser of 100
shareholders or shareholders representing 5% of the total voting power eligible
to vote at the meeting at which the resolution is proposed to be passed. Unless
Harbor Global determines otherwise, the resolution and notice will be circulated
at the expense of the shareholders making the requisition. The requisition
proposing a resolution must be deposited at the registered office of the company
not less than six weeks before the annual general meeting.

                                       48
<PAGE>   172

     Access to Books and Records and Dissemination of Information.  Members of
the general public have the right to inspect the public documents of a Bermuda
company which are available at the office of the Registrar of Companies in
Bermuda. These documents include:

     - Harbor Global's memorandum of association; and

     - any amendment of Harbor Global's memorandum of association.

     In addition, under Bermuda law Harbor Global's shareholders have the right
to inspect:

     - Harbor Global's bye-laws;

     - minutes of Harbor Global's general meetings; and

     - audited financial statements of Harbor Global, which must be presented to
       shareholders at the annual general meeting.

     Additionally, Harbor Global's register of shareholders is open to
inspection by its shareholders free of charge and to members of the general
public upon the payment of a fee. Harbor Global is required to maintain its
share register in Bermuda. Harbor Global is required to keep at its registered
office a register of its directors and officers which is open for inspection for
not less than two hours each day by members of the public without charge. Other
than as described above, Bermuda law does not provide a general right for
shareholders to inspect or obtain copies of any other corporate records.

     Amendment of Memorandum of Association and Bye-laws.  Bermuda law provides
that the memorandum of association of a company may be amended by a resolution
passed at a general meeting of shareholders after due notice has been given. An
amendment to the objects set out in Harbor Global's memorandum of association
may require the approval of the Bermuda Minister of Finance, who may grant or
withhold approval at his or her discretion. Under Bermuda law, the directors may
amend the bye-laws with the approval of the shareholders representing a majority
of Harbor Global's outstanding voting shares at a general meeting.

     Under Bermuda law, the holders of at least 20% of any class of a company's
issued share capital have the right to apply to the Bermuda courts for an
annulment of any amendment to the company's memorandum of association adopted by
shareholders at any general meeting, other than an amendment which alters or
reduces a company's share capital as provided in the Companies Act. Where such
an application is made, the amendment becomes effective only to the extent that
it is confirmed by the Bermuda courts. An application for annulment of any
amendment of the memorandum of association must be made within 21 days after the
date on which the resolution altering the company's memorandum is passed and may
be made on behalf of the persons entitled to make the application by one or more
of shareholders as they may appoint in writing for that purpose. Persons voting
in favor of an amendment may not make an application for its annulment.

     Duties of Directors and Officers.  The Companies Act 1981 imposes a duty to
act honestly and in good faith with a view to the best interests of the company
and exercise the care, diligence and skill that a reasonably prudent person
would exercise in comparable circumstances upon each director and officer of a
Bermuda company. A Bermuda court is unlikely to interfere with decision of
directors unless one of these two duties is breached. The court must find that
the director acted in bad faith or that no reasonable board of directors could
have come to the decision that was reached.

     Interested Directors.  Harbor Global's bye-laws provide that any director,
or a firm, partner or company associated with a director, may act in a
professional capacity for Harbor Global, and will be entitled to remuneration
for those services. However, a director or a firm, partner or company associated
with a director, may not act as auditor of Harbor Global's accounts.

     The bye-laws also provide that a director who has a direct or indirect
material interest, in a contract or other arrangement with Harbor Global must
disclose the nature of his or her interest as required by the Companies Act.
Following this disclosure, unless the chairman of the board of directors
disqualifies the interested director, the interested director may be counted in
the quorum and vote in respect of any
                                       49
<PAGE>   173

contract or other arrangement in which he or she is interested and will not be
liable for any profit realized in connection with the contract or other
arrangement.

     Appraisal Rights and Shareholder Suits.  Under Bermuda law, in the event of
a consolidation, amalgamation or merger with one or more companies, if a
shareholder is not satisfied that fair value has been offered for his or her
shares, he or she may apply to the Bermuda courts to appraise the fair value of
the shares.

     Except as described below, class actions and derivative actions against a
Bermuda company are not available to shareholders under Bermuda law. Bermuda
courts ordinarily would be expected to follow English case law precedent, which
would permit a shareholder to commence an action in the name of a company to
remedy a wrong done to the company where the act complained of is alleged to be
an act that cannot be confirmed by a majority of shareholders because the act:

     - is beyond the corporate power of the company;

     - is illegal;

     - is a fraud on the minority shareholders and the wrongdoers are in control
       of the company; or

     - infringes personal rights of an individual shareholder.

     When the affairs of a company are being conducted in a manner oppressive or
prejudicial to the interests of one or more of the shareholders, a shareholder
may apply to the Bermuda courts for an order to regulate the company's conduct
of affairs in the future or order the purchase of the shares held by the
shareholder by other shareholders or by the company.

     Mergers and Similar Arrangements.  Harbor Global may acquire the business
of another Bermuda company similarly exempt from Bermuda taxes or a company
incorporated outside Bermuda and carry on the acquired company's business when
it is within the corporate powers specified in its memorandum of association.
Harbor Global may also consolidate, amalgamate or merge with another Bermuda
company or with a body incorporated outside Bermuda upon the approval of the
board of directors and the holders of a majority of the outstanding shares of
the company, including any shares that would otherwise be non-voting shares.

     Takeovers.  Bermuda law provides that where an offer is made for shares of
another company and within four months of the offer, the holders of not less
than 90% of the shares which are the subject of the offer accept the offer, the
offeror may give notice to the non-tendering shareholders requiring them to
transfer their shares to the offeror on the same terms as the initial offer.
Dissenting shareholders may object to the transfer by applying to the Bermuda
courts for relief within one month of the offeror's notice. The burden is on the
dissenting shareholders to show that the court should exercise its discretion to
enjoin the required transfer, which a Bermuda court will be unlikely to do
unless there is evidence of fraud, bad faith or collusion between the offeror
and the holders of the shares who have accepted the offer as a means of unfairly
forcing minority shareholders out of the company.

LIMITATION OF LIABILITY AND INDEMNIFICATION

     Harbor Global's bye-laws provide that it will indemnify its directors,
officers and any liquidator or trustee acting in relation to any of Harbor
Global's affairs, including the heirs, executors or administrators of these
indemnified persons, from all expenses incurred as a result of any act done,
concurred in or omitted in execution of their duty, so long as the action or
inaction does not involve fraud or dishonesty. In addition, Harbor Global's
bye-laws also provide that each shareholder agrees to waive any claim or right
of action, whether individually or by right of Harbor Global, against any
director or officer as a result of any action taken or omitted in execution of
his or her duty, so long as the action or inaction does not involve fraud or
dishonesty or the recovery of any gain, personal profit or advantage to which
the director or officer is not legally entitled.

                                       50
<PAGE>   174

     Currently, there is no pending litigation or proceeding involving any
director, officer, liquidator or trustee of Harbor Global in which
indemnification will be required or permitted. Harbor Global is not aware of any
threatened or pending litigation or proceeding which may result in a claim for
indemnification.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for Harbor Global's common shares is
EquiServe Limited Partnership.

MATERIAL FOREIGN ISSUER CONSIDERATIONS

     Foreign Exchange Control Regulations.  Harbor Global has obtained the
permission of the Bermuda Monetary Authority for the distribution of its common
shares to you and has been designated by the Bermuda Monetary Authority as a
non-resident exempted company for exchange control purposes. As such, Harbor
Global is exempted from the provisions of Bermuda law that require at least 60%
of a Bermuda company's equity to be owned by Bermudians. This designation allows
Harbor Global to engage in transactions, or to pay dividends to non-residents of
Bermuda who are holders of Harbor Global common shares in currencies other than
the Bermuda Dollar.

     The transfer of shares between persons regarded as resident outside Bermuda
for exchange control purposes and the issue of shares after the completion of
distribution to or by non-resident persons may take place without specific
consent under the Exchange Control Act 1972. The issuance or transfer of shares
involving any person regarded as resident in Bermuda for exchange control
purposes requires specific prior approval of the Bermuda Monetary Authority
under the Exchange Control Act 1972.

     Harbor Global shareholders who are not Bermuda residents are not restricted
in the exercise of the rights to hold or vote their shares. Because Harbor
Global has been designated as a non-resident for Bermuda exchange control
purposes, there are no restrictions on its ability to transfer funds in and out
of Bermuda or to pay dividends to United States residents who are holders of
Harbor Global common shares, as long as the transactions are not effected in the
Bermuda Dollar.

     Under Bermuda law, registration of share ownership is only required to be
in the names of corporations or individuals. In the case of an applicant acting
in a special capacity (for example as a trustee), the register may, at the
request of the applicant, record the capacity in which the applicant is acting,
but Harbor Global is not bound to investigate or incur any responsibility in
respect of the proper administration of the trust. Harbor Global will take no
notice of any trust applicable to any of its shares whether or not it has notice
of the trust.

     As an exempted company, Harbor Global may not participate in certain
business transactions, including:

     - acquiring or leasing land in Bermuda, except as required for Harbor
       Global's business and then for a term of not more than 50 years, without
       the express authorization of the Bermuda legislature;

     - taking mortgages on land in Bermuda to secure an amount in excess of
       $50,000 without the consent of the Bermuda Minister of Finance;

     - the acquisition of any bonds or debentures secured by any land in
       Bermuda, other than certain types of Bermuda government securities; or

     - carrying on business of any kind in Bermuda, except in furtherance of
       Harbor Global's business carried on outside Bermuda or under a license
       granted by the Bermuda Minister of Finance.

     The Bermuda government actively encourages foreign investment in exempted
entities which, like Harbor Global, are based in Bermuda but do not operate in
competition with local business.

     Reciprocal Recognition and Enforcement of Civil Judgements.  Harbor Global
has been advised by its legal counsel in Bermuda that the United States and
Bermuda currently do not have a treaty providing for
                                       51
<PAGE>   175

the reciprocal recognition and enforcement of judgments in civil and commercial
matters. A final judgment for the payment of money rendered by any federal or
state court in the United States based on civil liability, whether or not based
solely on United States federal securities laws, would therefore not be
automatically enforceable in Bermuda.

     Nevertheless, a final and conclusive judgment obtained in a state court or
federal court of the United States based upon a contractual obligation under
which a sum of money is payable could be enforced by an action in the Supreme
Court of Bermuda, without reexamination of the merits, under the common law
doctrine of obligation. A final opinion as to the availability of this remedy
could only be given when the facts surrounding the judgment were known but,
generally, based on advise from its legal counsel in Bermuda, Harbor Global
would expect an application to be successful if the judgment:

     - was final and conclusive;

     - was not obtained by fraud;

     - was not, and its enforcement would not be, contrary to the public policy
       of Bermuda;

     - was not obtained in circumstances where the proceedings were contrary to
       the rules of natural justice;

     - complied with procedures under Bermuda law for its enforcement; and

     - no new evidence is submitted to the Bermuda courts.

     A Bermuda court may impose civil liability on Harbor Global or its
directors or officers in a suit brought in the Supreme Court of Bermuda against
Harbor Global or those persons with respect to a violation of United States
securities if the facts surrounding the violation would constitute or give rise
to a cause of action under Bermuda law.

     Bermuda Taxation.  Under current Bermuda law, there is no Bermuda income
tax, withholding tax, capital gains tax or capital transfer tax levied on Harbor
Global or its shareholders. The United States and Bermuda do not currently have
a reciprocal treaty regarding withholding taxes that is applicable to Harbor
Global.

     Harbor Global and its Bermuda subsidiaries have each applied for a written
undertaking from the Bermuda Minister of Finance under the Exempted Undertakings
Tax Protection Act, 1966, as amended, that, in the event any legislation
imposing tax computed on profits or income, or on any capital asset, gain or
appreciation, or any tax in the nature of estate duty or inheritance tax is
enacted in Bermuda, the tax will not be applicable to Harbor Global or any of
its operations, or to the shares, debentures or other obligations of Harbor
Global until 2016, except insofar as the tax applied to Bermuda residents
holding shares, debentures or other obligations of Harbor Global or to any
Bermuda land leased by Harbor Global.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Harbor Global Company Ltd.:

     After the reorganization transaction discussed in Note 1 to Harbor Global
Company Ltd.'s consolidated financial statements is effected, we expect to be in
a position to render the following audit report.

                                          /s/ ARTHUR ANDERSEN LLP

Boston, Massachusetts
June 9, 2000

     We have audited the accompanying consolidated balance sheets of Harbor
Global Company Ltd. (a Bermuda limited duration company) as of December 31, 1999
and 1998 and the related consolidated statements of operations, changes in net
parent company investment (deficit) and cash flows for each of the three years
in the period ended December 31, 1999. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Harbor
Global Company Ltd. as of December 31, 1999 and 1998 and the results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1999 in conformity with accounting principles generally accepted in
the United States.

     As explained in Note 2 to the consolidated financial statements, effective
January 1, 1999, the Company changed its method of accounting for start-up
costs.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               December 31, 1999

(1) BACKGROUND AND BASIS OF PRESENTATION

BACKGROUND

     On May 14, 2000, The Pioneer Group, Inc. (Pioneer) entered into a merger
agreement with UniCredito Italiano S.p.A., an Italian Corporation (UniCredito)
under which a wholly owned subsidiary of UniCredito will merge with and into
Pioneer, with Pioneer surviving the merger as a wholly owned subsidiary of
UniCredito. As a condition to closing the merger, Pioneer has agreed to transfer
some of its assets to Harbor Global Company Ltd. (the Separation), a newly
formed wholly owned Bermuda limited duration company (the Company), and, before
closing the merger, to distribute all the outstanding common shares of the
Company to stockholders of Pioneer (the Distribution).

     At the time of the Distribution, the Company's assets will primarily
consist of: real estate management and investment management operations in
Russia; Polish and Eastern European venture capital investment and management
operations; Polish and Eastern European real estate management operations;
timber harvesting and sales in Russia; gold exploration operations in Russia;
approximately $30 million in cash, of which $5 million is restricted to satisfy
liabilities associated with Pioneer's former gold mining operations;
approximately $3.6 million of liabilities related to certain compensation
liabilities payable to current employees of Pioneer who will become employees of
Harbor Global or Calypso Management; and a non-interest-bearing promissory note
with a face value of $13.8 million, payable to Pioneer Goldfields II, a wholly
owned subsidiary of the Company.

     The Russian real estate and investment management operations consist of an
81% owned Russian investment management company (JSC Pioneer First), an 81%
owned Russian stockholder services company (JSC Pioneer Services), and on
approximately 52% interest held in the Pioneer First Investment Fund, a Russian
joint stock company managed by JSC Pioneer First. Pioneer First Investment Fund
invests directly in real estate and securities of Russian companies. A
significant portion of the assets of Pioneer First Investment Fund consists of
its ownership of the Meridian Commercial Tower, an 18-story, 22,600 square-meter
office building in Moscow, Russia. Under a management agreement between JSC
Pioneer First and Pioneer First Investment Fund, JSC Pioneer First has agreed to
provide management services to Pioneer First Investment Fund for an annual fee
of five percent of gross assets less any value-added taxes or similar taxes.
Through December 31, 1999, JSC Pioneer Services provided shareholder services to
Pioneer First Investment Fund and two Russian open-end unit investment funds
managed by JSC Pioneer First.

     The Polish and Eastern European venture capital investment and management
operations consist primarily of the Pioneer Poland Fund. At December 31, 1999,
the Pioneer Poland Fund had approximately $60 million in commitments from U.S.
and European investors, of which approximately $40 million had been invested in
privately held Polish companies.

     The Polish and Eastern European real estate management operations are
conducted by PREA, LLC (formerly, Pioneer Real Estate Advisors, Inc.) (PREA).
PREA provides real estate investment opportunities in Poland and Eastern Europe
to institutional investors through two pooled investment funds, the Polish Real
Estate Fund and the PBO Property Fund, LLC. PREA also provides management
services for the Meridian Commercial Tower.

     The Russian timber harvesting and sales operations consist of
Forest-Starma's operations. Forest-Starma, which is located on the Siziman Bay
in the Vanino district of the Khabarovsk Territory of the Russian Far East, owns
and operates a modern logging camp, including a harbor facility, from which it
exports timber to markets in the Pacific Rim, primarily Japan and South Korea.
Two other entities in this segment, JSC Udinskoye and JSC Amgun-Forest, are both
in the development stage. All of these entities have signed long-term leases
relating to timber harvesting in the Russian Far East.

           Notes to Consolidated Financial Statements -- (Continued)
                               December 31, 1999

     The Russian gold exploration operations consist of Tas-Yurjah's operations.
Tas-Yurjah conducts the exploration of potential gold mining properties over
concession areas in the Ayano-Maysky district of the Khabarovsk Territory.
Tas-Yurjah is included in the Company's "Other" segment (see Note 14).

     Pioneer is in the final stages of closing its Russian brokerage operations
and, as such, has reported the results of those operations as discontinued
operations. Additionally, Pioneer sold its Russian banking operations in 1999
and the historical results are reflected as a discontinued operation. These
companies will not be included as part of the legal separation due to a prior
liquidation or sale. However, as they were subsidiaries of Pioneer First Russia,
the 81% owned subsidiary of the Company, the results of these operations have
been included in these consolidated financial statements.

BASIS OF PRESENTATION

     The consolidated financial statements reflect the results of operations,
financial position, changes in net parent company investment (deficit), and cash
flows of the businesses that will be transferred to the Company from Pioneer in
the Separation (the Company Businesses) as if the Company were a separate entity
for all periods presented. The consolidated financial statements have been
prepared using the historical basis in the assets and liabilities and historical
results of operations related to the Company Businesses. Changes in net parent
company investment (deficit) represent the net losses of the Company plus net
cash transfers to or from Pioneer and noncash transfers to or from Pioneer.
Additionally, the consolidated financial statements include allocations of
certain Pioneer expenses relating to the Company Businesses that will be
transferred to the Company from Pioneer. All material intercompany transactions
and balances between the Company Businesses have been eliminated.

     Certain costs historically have been incurred on the Company's behalf by
Pioneer. These costs relate to shared activities, such as executive, legal,
finance, human resources, and information technology support. The shared
activities costs are allocated to all Pioneer business units and the Company
based upon estimated time spent and the actual compensation costs of the
departments performing shared activities. Additionally, certain other costs that
are directly attributable to the operations of the Company, such as salary and
benefits costs of Pioneer employees who have worked exclusively for the Company,
and other direct costs, including travel, entertainment, gold exploration costs
and political risk insurance, are allocated to the Company. The costs of the
shared services charged to the Company are not necessarily indicative of the
costs that would have been incurred if the Company had performed these functions
as a stand-alone entity. Subsequent to the Distribution, the Company will
perform these shared functions using its own resources or purchased services and
will be responsible for the costs and expenses associated with the management of
an independent public corporation. Additionally, income taxes are calculated
using the separate-tax-return method.

     The Company is expected to enter into an administration and liquidation
agreement with Calypso Management LLC (the Manager) under which the Manager will
manage the liquidation of the Company and operate the Company's assets pending
liquidation in exchange for a fee (see Note 10).

     The consolidated financial information included herein may not necessarily
reflect the consolidated results of operations, financial position, changes in
net parent company investment (deficit), and cash flows of the Company in the
future or what they would have been had it been a separate, stand-alone entity
during the periods presented.

RUSSIAN ENVIRONMENT

     In recent years, Russia has undergone substantial political, economic, and
social change. As an emerging market, Russia does not possess a well developed
business, legal, and regulatory infrastructure

                               December 31, 1999

that would generally exist in a more mature free-market economy. As a result,
operations carried out in Russia involve significant risks that are not
typically associated with those in developed markets. Such risks have been
evidenced by the government's inability to meet its obligations under its
short-term ruble denominated treasury bills (GKOs) and certain other ruble and
foreign currency denominated securities. The government also announced a
widening of the ruble-trading corridor, which was soon abandoned, and a
moratorium on certain foreign currency payments.

     The economic conditions in Russia, together with actions of the Russian
government, led to a severe devaluation of the ruble, a sharp increase in the
rate of inflation, the near collapse of the banking system, significant defaults
on foreign currency obligations, a dramatic decline in the prices of Russian
debt and equity securities, and an inability to raise funds in the international
capital markets during 1998 and 1999. Although recent performance has improved,
the Russian economy since August 1998 generally has been characterized by rising
unemployment and underemployment, high government debt relative to gross
domestic product, high levels of trade credit, high levels of corporate
insolvency, highly volatile foreign currency exchange and interest rates, and an
unstable stock market.

ASIAN CRISIS

     The Company has been and for the foreseeable future will continue to be
affected by the unstable economies in the Asian-Pacific region. The Company's
timber sales are primarily made to this region. During 1998, timber sales prices
were significantly depressed and, although prices increased in the last quarter
of 1998 and in 1999, there is uncertainty as to whether this trend will
continue. This will be dependent upon the recovery in the economies of countries
in this region.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, PRINCIPLES OF CONSOLIDATION

CONSOLIDATION

     The accompanying consolidated financial statements include the Company's
wholly owned and majority-owned subsidiaries and certain partnerships that it
controls. Intercompany transactions and balances have been eliminated. The
Company has consolidated the Pioneer Poland U.S., L.P. and Pioneer Poland UK,
L.P. in which the Company's ownership interests are 7.2% and 9.2%, respectively.
Control is defined by several factors, including, but not limited to, the fact
that the Company is the general partner of both Pioneer Poland U.S., L.P. and
Pioneer Poland UK, L.P., the general partner has absolute and unilateral
authority to make investment decisions, the limited partners may not remove the
general partner, and the general partner has absolute and unilateral authority
to declare, or not to declare, distributions of partnership income to the
partners. Investments in which the Company exercises significant influence but
which it does not control (generally a 20% to 50% ownership interest) are
accounted for under the equity method of accounting. Investments in which the
Company has less than a 20% ownership interest are generally accounted for under
the cost method of accounting.

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. The most
significant estimates with regard to these consolidated financial statements
relate to the valuation of investments of the Pioneer First Investment Fund and
venture capital investments and the estimated future cash flows of the Company's
timber operations, as discussed herein.

           Notes to Consolidated Financial Statements -- (Continued)
                               December 31, 1999

CONSOLIDATED STATEMENT OF CASH FLOWS

     Cash and cash equivalents consist primarily of cash on deposit in banks.
The Company had approximately $880,000 and $1,513,000 of restricted cash as of
December 31, 1999 and 1998, respectively. The cash is restricted due to certain
provisions of the loan agreement between Forest Starma and the Overseas Private
Investment Corporation (OPIC) (see Note 4). Pioneer, as required under the
agreement with UniCredito, intends to repay the OPIC debt prior to the
Distribution.

INVENTORIES

     Inventories are stated at the lower of average cost or net realizable
value.

DEFERRED TIMBER DEVELOPMENT COSTS

     Deferred timber development costs consist of construction and engineering
expenditures and infrastructure costs incurred in developing the site and the
roads, as well as capitalized interest. These costs are amortized on a
units-of-production basis, which anticipates recovery principally over 10 years.
Certain other deferred timber development costs, including legal,
organizational, and other preoperating costs, were expensed in connection with
the adoption of an American Institute of Certified Public Accountants Statement
of Position (SOP) 98-5, Reporting on the Costs of Start-up Activities,effective
January 1, 1999.

GOODWILL

     Pioneer acquired its Russian real estate management and investment
management operations in 1995 for approximately $20,000,000. At inception, the
excess of the purchase price over the estimated fair value of the assets
approximated $2,858,000. As of December 31, 1999 and 1998, goodwill totaled
approximately $1,524,000 and $1,810,000, respectively, and is being amortized
over 10 years. Amortization expense was approximately $286,000 for both 1999 and
1998. At December 31, 1999 and 1998, the accumulated amortization of goodwill
was approximately $1,334,000 and $1,048,000, respectively.

TIMBER EQUIPMENT

     Timber equipment and facilities consist of a jetty, logging machinery, and
building and housing units. These costs are principally depreciated on a
units-of-production basis, which anticipates recovery over 5 to 20 years. Major
renewals and improvements are capitalized, while maintenance and repairs are
expensed when incurred. In the event of retirement or other disposition of a
fixed asset, the cost of the asset and the related accumulated depreciation or
amortization amount is removed from the accounts and any resulting gain or loss
is reflected in earnings.

BUILDING

     The building represents the Meridian Commercial Tower in Russia. The
Meridian Commercial Tower is an office building that is wholly owned by the
Pioneer First Investment Fund. The building is being

</TABLE>

     The Company's venture capital investments are made through certain of its
consolidated partnerships. The venture capital investments are in companies that
are domiciled in Poland and are primarily engaged in bringing new technology to
market, as well as more mature companies in need of capital for expansion,
acquisitions, management buyouts, or recapitalizations. At the time the
investments are made, the investments are primarily in the form of unregistered
common and preferred stock, warrants, and promissory notes. No market quotes are
available for the venture capital investments.

     Most of the Company's venture capital investments are valued at fair value,
as determined in good faith by management. In determining fair value,
investments are initially stated at cost until significant subsequent events
require a change in valuation. The Company considers the financial condition and
operating results of the investee, prices paid in subsequent private offerings
of the same or similar securities, the amount that the Company can reasonably
expect to realize upon the sale of these securities, and other factors deemed
relevant.

LONG-TERM INVESTMENTS

     Long-term investments consist of Russian investments of the Pioneer First
Investment Fund. These securities are carried at cost with adjustments made for
any other-than-temporary impairment in value until such time as the breadth and
scope of the Russian securities markets develop to certain quantifiable levels.
The carrying value of these securities was approximately $6,712,000 and
$7,006,000 at December 31, 1999 and 1998, respectively. Management estimated the
approximate fair value of these securities was $20,600,000 and $13,400,000 at
December 31, 1999 and 1998, respectively, (based upon available market
quotations and appraisals).

VALUATION OF FINANCIAL INSTRUMENTS

     The Company considers the available market quotations when estimating fair
value of financial instruments. As stated in the accompanying consolidated
balance sheets, the carrying values of the Company's financial instruments
approximate fair value, except for the long-term investments of Pioneer First
Investment Fund, as discussed above.

LOSS PER SHARE

     On the date of Distribution, shareholders of Pioneer will receive one share
of the Company for every five Pioneer shares they own. The loss per share has
been computed assuming that the shares expected to be issued on the distribution
date were outstanding for all periods presented.

     The following table provides a reconciliation of the numerators and
denominators of the basic and diluted loss per share calculation:

     The Company had no stock options or other common stock equivalents
outstanding during the periods presented.

COMPREHENSIVE LOSS

     The Company adopted Statement of Financial Accounting Standards (SFAS) No.
130, Reporting Comprehensive Income. SFAS No. 130 establishes standards for the
reporting of comprehensive income and its components. Comprehensive income, as
defined, includes all changes in equity during a period from nonowner sources.

FOREIGN CURRENCY TRANSLATION

     In accordance with SFAS No. 52, Foreign Currency Translation, the
functional currency of the Company's timber operation is the U.S. dollar, as the
revenues, costs of capital equipment, and financing costs are principally
denominated in U.S. dollars. The functional currency of the Company's financial
services operations is generally the currency of the country in which those
operations are conducted. However, some of those operations are conducted in
countries having highly inflationary economies and, as a result, the functional
currency is currently the U.S. dollar. For those entities, the gains and losses
that result from remeasuring into the U.S. dollar for reporting purposes are
included in the accompanying consolidated statements of operations. The net
foreign currency losses were approximately $135,000 in 1999, $1,705,000 in 1998,
and $515,000 in 1997.

LONG-LIVED ASSETS

     The Company reviews its long-lived assets for impairment whenever events or
changes in circumstances indicate that the carrying value of the asset may not
be recoverable. In accordance with SFAS No. 121, Accounting for the Impairment
of Long-Lived Assets and for the Long-Lived Assets to Be Disposed Of, the
Company uses an estimate of the future undiscounted cash flows of the related
asset or asset grouping in measuring whether the assets are impaired. If any
impairment is identified, an impairment charge is recorded to write down the
assets by the excess of the carrying value over fair value. The Company
periodically reviews its long-lived assets and assesses the future useful life
of these assets whenever events or changes in circumstances indicate that the
current useful life has diminished.

CONCENTRATION OF RISK

     The Company's operations are concentrated in Russia and Eastern Europe.
Additionally, the Company's timber project sells its timber primarily in the
Asian markets. The Company performs ongoing

evaluations of its subsidiaries and investments and obtains political risk
insurance, which mitigates its exposure in foreign countries (see Note 14).

CHANGE OF ACCOUNTING PRINCIPLE

     On January 1, 1999, the Company adopted SOP 98-5. This standard requires
that entities expense costs of start-up activities as those costs are incurred.
The Company previously capitalized certain preoperating costs in connection with
its natural resource operations and certain organizational costs associated with
its financial services operations. In the first quarter of 1999, the Company
recorded the cumulative effect of a change in accounting principle and wrote off
unamortized capitalized start-up costs, net of tax, of approximately
$11,547,000. The amount of pro forma net income in 1998 giving effect to the
change in accounting principle did not differ materially from the amount
reported in 1998.

return method allocates current and deferred taxes to members of a group by
applying the provisions of SFAS No. 109 to each member as if it were a separate
tax payer.

     The Company is a Bermuda limited duration company and will not be subject
to taxation in Bermuda. The Company currently has subsidiaries located in the
United States. Prior to the Separation, the results of these subsidiaries have
been included in the U.S. federal consolidated tax returns of Pioneer. Under the
separate-return method, the losses incurred in the United States have not been
benefited. However, Pioneer has made capital contributions to the Company in
exchange for the tax benefits that Pioneer realized. In connection with the
Separation, the U.S. subsidiaries will be recharacterized as partnerships for
U.S. tax purposes. The income tax provisions and the deferred taxes included in
the accompanying consolidated financial statements relate to the Company's
corporate subsidiaries that are located primarily in Russia and Poland.

     The components of the provision for foreign income taxes on continuing

     Pioneer, the Company and Harbor Global II Ltd., a wholly owned subsidiary
of the Company, will enter into a tax separation agreement before consummation
of the Distribution. Under the tax separation agreement, the Company will agree
to indemnify Pioneer for any income tax obligations arising from the Separation
and Distribution.

(8)  MINORITY INTEREST

     The Company's minority interest liability includes the interests of the
other equity holders of the Company's consolidated entities. The liability for
each entity is recorded based upon the net book value of that entity at the
balance sheet date, except for those instances in which agreements could result
in the Company redeeming those interests at amounts greater than their share of
the net book value. In those instances, adjustments are made to the liability to
reflect the minority equity holders' economic interests under those agreements.
As of December 31, 1999 and 1998, the Company's minority interest liability
consisted of the following:

the accompanying consolidated financial statements. In 1999, 1998, and 1997,
these costs were approximately $164,000, $157,000 and $125,000 respectively.

(10)  RELATED PARTY TRANSACTIONS

     The Company is expected to enter into an administration and liquidation
agreement with the Manager, under which the Manager will manage the liquidation
of the Company and operate the Company's assets as going concern businesses
until they are liquidated. The principal executive officers of the Company will
also serve as the principal executive officers of the Manager. These officers
are currently officers of Pioneer. Under the management agreement, the Company
has agreed to pay certain expenses of the Manager incurred in connection with
its provision of services and a percentage of the net proceeds realized from the
liquidation of its assets.

(11) COMMITMENTS

     The Company has committed to contribute up to $5,700,000 for Class B shares
of the Pioneer Poland Real Estate Fund, of which approximately $300,000 has been
contributed as of December 31, 1999. Additionally, the Company has also
committed to contribute $4,000,000 for shares of the PBO Property Fund, of which
$1,384,000 has been contributed as of December 31, 1999. The Company also
provides management and advisory services to these funds.

     Pioneer First Russia (PFR), a subsidiary of the Company, is part of the
Russian real estate and investment management operations and is the parent of
JSC Pioneer First and JSC Pioneer Services. In 1996, PFR issued approximately
18% of its common stock in exchange for $4,000,000. At the same time, PFR
entered into a put and call agreement with respect to the common stock. The put
allows the holder to put the shares to PFR for the greater of a defined book
value or 12 times the holder's share of PFR's average earnings, as further
defined in the agreement. This put is effective from October of 2000 through
October of 2004. The liability recorded in connection with the put was
approximately $1,900,000 and $2,000,000 at December 31, 1999 and 1998,
respectively, and is included in both the minority interest liability and the
net noncurrent assets of discontinued operations in the accompanying
consolidated balance sheet.

(12) DISCONTINUED OPERATIONS

     Pioneer Securities and UKS Securities Ltd. previously traded in various
Russian securities on behalf of customers and, to a lesser extent, on their own
account. In 1999, the decision was made by management of the Company to close
the operations of these two companies after all transfers of customers'
positions were complete. No loss was realized in connection with the closure.

     In the third quarter of 1998, the Company decided to liquidate its Russian
banking operations. The 1998 loss included a provision of approximately
$3,600,000 for costs and certain losses associated with liquidating the bank. In
December 1998, the Company sold its stock in the bank to an unrelated third
party.

(13) TIMBER OPERATIONS

     In connection with the filing of its 1999 income tax return, Pioneer
realized approximately $15,300,000 of income tax benefits associated with the
timber operations. In connection with the realization of the income tax
benefits, Pioneer recorded an equal offsetting reduction in the carrying value
of its timber project. The reduction in the carrying value of the timber project
has been reflected in the accompanying consolidated statement of operations. As
the Company utilizes the separate return method for providing income taxes (see
Note 7), the income tax benefits have not been reflected in the accompanying
consolidated statement of operations.

(14) FINANCIAL INFORMATION BY BUSINESS SEGMENT

     The Company presents its segment information for continuing operations
using the management approach. The management approach is based on the way that
management organizes the segments within a Company for making operating
decisions and assessing performance. The Company's operating segments are
organized around services and products provided, as well as geographic regions.

          UNAUDITED NOTES TO CONSOLIDATED INTERIM FINANCIAL STATEMENTS
              as of and for the Three Months Ended March 31, 2000

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The accounting and reporting policies of the Company conform to generally
accepted accounting principles. The Company has not changed any of its principal
accounting policies from those stated in the consolidated financial statements
for the year ended December 31, 1999, included elsewhere in this information
statement.

     During the first quarter of 1999, the Company adopted the provisions of the
American Institute of Certified Public Accountants (the AICPA) SOP 98-5,
Reporting on the Costs of Start-Up Activities. SOP 98-5 requires that costs of
start-up activities be expensed as incurred. The Company had capitalized certain
pre-operating costs in connection with capitalized organizational costs
associated with its financial services operations and its natural resource
operations. Adoption of SOP 98-5 resulted in write-offs of $11.5 million, which
is reflected in the accompanying consolidated financial statements as a change
in accounting principle.

(2) FINANCIAL INFORMATION BY BUSINESS SEGMENT

     In accordance with SFAS No. 131, Disclosures about Segments of an
Enterprise and Related Information, the Company presents segment information
using the management approach. The management approach is based on the way that
management organizes the segments within a Company for making operating
decisions and assessing performance. The Company's operating segments are
organized around services and products provided, as well as geographic regions.

     The following details selected financial information by business segment
(dollars in thousands):

Claim. If the Indemnifying Party shall have assumed the defense of an
Indemnified Claim, the Indemnitee shall not admit any liability with respect to,
or settle, compromise or discharge, such Indemnified Claim without the
Indemnifying Party's prior written consent, which consent shall not be
unreasonably withheld, conditioned or delayed.

Distribution. Each party agrees that the Distribution is not a non-recognition
transaction satisfying the requirements of Section 355 of the Code.

     6.2  Harbor Global shall be entitled to review any Tax Return pertaining to
any Taxes for which Harbor Global may either be liable directly to the relevant
Taxing Authority or for which it may be required to indemnify any member of the

for the purpose of the review or audit of such returns to the extent relevant to
an obligation or liability of a party under this Tax Separation Agreement.

Board of Directors
The Pioneer Group, Inc.
60 State Street
Boston, Massachusetts 02109

Ladies and Gentlemen:

     The Pioneer Group, Inc. (the "Company"), UniCredito Italiano S.p.A. (the
"Acquiror") and a wholly owned subsidiary of the Acquiror (the "Acquisition
Sub"), have entered into an Agreement and Plan of Merger, dated as of May 14,
2000 (the "Agreement"), pursuant to which the Company will be merged with the
Acquisition Sub in a transaction (the "Merger") in which each outstanding share
of the Company's common stock par value $.10 per share (the "Shares"), will be
converted into the right to receive $43.50 in cash (the "Merger Consideration").
Prior to the Merger, the Company will distribute (the "Distribution") to holders
of Company Common Stock all of the capital stock of Harbor Global Company Ltd. a
Bermuda limited duration company ("Harbor Global") which at such time will hold
substantially all of the Company's assets and liabilities not related to the
Company's global investment management business (the "GIM Business").

     You have asked us whether, in our opinion, the aggregate consideration to
be received by the holders of the Shares other than the Acquiror and its
affiliates in the Merger and the Distribution is fair to such shareholders from
a financial point of view.

     In arriving at the opinion set forth below, we have, among other things:

     (1) Reviewed the Company's Annual Reports, Forms 10-K and related financial
         information for the five fiscal years ended December 31, 1999 and the
         Company's Form 10-Q and the related unaudited financial information for
         the quarterly period ending March 31, 2000;

     (2) Reviewed certain information, including financial forecasts, relating
         to the business, earnings, cash flow, assets and prospects of the
         Company, furnished to us by the Company;

     (3) Conducted discussions with members of senior management of the Company
         concerning the businesses and prospects of the Company;

     (4) Reviewed the historical market prices and trading activity for the
         Shares and compared them with that of certain publicly traded companies
         which we deemed to be reasonably similar to the GIM Business;

     (5) Compared the results of operations of the GIM Business with that of
         certain companies which we deemed to be reasonably similar to the GIM
         Business;

     (6) Compared the proposed financial terms of the transactions contemplated
         by the Agreement with the financial terms of certain other mergers and
         acquisitions which we deemed to be relevant;

     (7) Reviewed the Agreement and certain drafts of the agreements relating to
         the Distribution;

     (8) Reviewed a letter (the "Solvency Letter") regarding the solvency and
         financial viability of Harbor Global following the Distribution and
         discussed its contents with the Company's management and the third
         party which proposed such letter; and

                                       C-1
<PAGE>   233

     (9) Reviewed such other financial studies and analyses and performed such
         other investigations and took into account such other matters as we
         deemed necessary, including our assessment of general economic, market
         and monetary conditions

     In preparing our opinion, we have relied on the accuracy and completeness
of all information supplied or otherwise made available to us by the Company,
and we have not independently verified such information or undertaken an
independent appraisal of the assets of the Company. With respect to the
financial forecasts furnished by the Company, we have assumed that they have
been reasonably prepared and reflect the best currently available estimates and
judgment of the Company's management as to the expected future financial
performance of the GIM Business. In addition, we have relied upon the Solvency
Letter and have assumed that as set forth in the Solvency Letter, Harbor Global
will be solvent and financially viable at the time of the Distribution.

     On the basis of, and subject to the foregoing, we are of the opinion that
the aggregate consideration to be received by the holders of the Shares other
than the Acquiror and its affiliates pursuant to the Merger and the Distribution
is fair to such shareholders from a financial point of view.

                                          Very truly yours,

                                          MERRILL LYNCH, PIERCE, FENNER &

[Date]

Board of Directors
The Pioneer Group, Inc.
60 State Street
Boston, Massachusetts 02109

Ladies and Gentlemen:

     You have requested our opinion as to the fairness, from a financial point
of view, to the holders of shares of the common stock, par value $0.10 per share
(the "Company Common Stock"), of The Pioneer Group, Inc. (the "Company") of the
aggregate consideration to be received by holders of the Company Common Stock in
the Merger and the Distribution (each as defined below) contemplated by the
Agreement and Plan of Merger (the "Agreement"), dated as of May 14, 2000, by and
between the Company, UniCredito Italiano S.p.A. ("Parent") and a direct wholly
owned subsidiary to be organized by Parent ("Merger Sub").

     As more specifically set forth in the Agreement, and subject to the terms
and conditions thereof, Merger Sub will merge with and into the Company (the
"Merger"), and each issued and outstanding share of Company Common Stock, other
than certain shares to be cancelled pursuant to the Agreement, will be converted
into the right to receive $43.50 in cash, without any interest thereon (the
"Merger Consideration"). Prior to the Merger, the Company will distribute (the
"Distribution") to holders of Company Common Stock all of the capital stock of
Harbor Global Company Ltd., a Bermuda limited duration company ("Harbor
Global"), which at such time will hold substantially all of the Company's assets
and liabilities not related to the Company's global investment management
business (the "GIM Business").

     In arriving at our opinion, we reviewed the Agreement and held discussions
with certain senior officers, directors and other representatives and advisors
of the Company concerning the businesses, operations and prospects of the GIM
Business. We examined certain publicly available business and financial
information relating to the Company as well as certain financial forecasts and
other information and data for the Company which were provided to or otherwise
discussed with us by the Company's management. We reviewed the financial terms
of the Merger as set forth in the Agreement in relation to, among other things:
current and historical market prices and trading volumes of the Company Common
Stock; the historical and projected earnings and other operating data of the GIM
Business; and the historical and projected capitalization and financial
condition of the Company and the GIM Business. We analyzed certain financial,
stock market and other publicly available information relating to the businesses
of other companies whose operations we considered relevant in evaluating those
of the GIM Business. We also reviewed the terms of the Distribution and a letter
(the "Solvency Letter") with respect to the solvency and financial viability of
Harbor Global following the Distribution following the Distribution and
discussed its contents with the Company's management and the third party which
proposed such letter. In addition to the foregoing, we conducted such other
analyses and examinations and considered such other information and financial,
economic and market criteria as we deemed appropriate in arriving at our
opinion.

     In rendering our opinion, we have assumed and relied, without independent
verification, upon the accuracy and completeness of all financial and other
information and data publicly available or furnished to or otherwise reviewed by
or discussed with us and have further relied upon the assurances of the
Company's management that it is not aware of any facts that would make any of
such information inaccurate or misleading. With respect to financial forecasts
and other information and data provided to or otherwise reviewed by or discussed
with us, we have been advised by the Company's management that such forecasts
and other information and data were reasonably prepared on bases reflecting the
best currently available estimates and judgments of the Company's management as
to the future financial performance of the GIM Business. We express no view with
respect to such forecasts and other

                                       D-1
<PAGE>   235

information and data or the assumptions on which they were based. We have not
made or been provided with an independent evaluation or appraisal of the assets
or liabilities (contingent or otherwise) of the GIM Business nor have we made
any physical inspection of the properties or assets of the GIM Business. We have
assumed that the Merger and the Distribution will be consummated in a timely
fashion in accordance with the terms of the Agreement without waiver of any of
the conditions precedent contained in the Agreement. In addition, we have relied
upon the Solvency Letter, and have assumed that as set forth in the Solvency
Letter, Harbor Global will be solvent and financially viable at the time of the
Distribution.

     We were not requested to consider, and our opinion does not address, the
relative merits of the Merger and the Distribution as compared to any
alternative business strategies that might exist for the Company or the effect
of any other transaction in which the Company might engage. Our opinion
necessarily is based upon information available to us and financial, stock
market and other conditions and circumstances existing and disclosed to us as of
the date hereof.

     Salomon Smith Barney Inc. is acting as financial advisor to the Company in
connection with the Merger and the Distribution and will receive a fee for our
services, a portion of which is payable only upon the consummation of the
transactions. We have in the past provided investment banking services to the
Company unrelated to the Merger and the Distribution, for which we have received
and will receive compensation. In the ordinary course of our business, we and
our affiliates may actively trade or hold the securities of the Company and
Parent for our own account or for the account of our customers and, accordingly,
may at any time hold a long or short position in such securities. Salomon Smith
Barney Inc. and its affiliates (including Citigroup Inc. and its affiliates) may
maintain relationships with the Company and Parent and their respective
affiliates.

     Our advisory services and the opinion expressed herein are provided for the
information of the Board of Directors of the Company in its evaluation of the
Merger and the Distribution and our opinion is not intended to be and does not
constitute a recommendation of the Merger or the Distribution to the Company or
a recommendation to any stockholder as to how such stockholder should vote on
any matters relating to the Merger or the Distribution.

     Based upon and subject to the foregoing, our experience as investment
bankers, our work as described above and other factors we deemed relevant, we
are of the opinion that, as of the date hereof, the aggregate consideration to
be received by the holders of shares of Company Common Stock in the Merger and
the Distribution is fair, from a financial point of view, to such holders.

                                          Very truly yours,

                                          [SALOMON SMITH BARNEY INC.]

                        DELAWARE GENERAL CORPORATION LAW
                        SECTION 262 -- APPRAISAL RIGHTS

     262  APPRAISAL RIGHTS.  (a) Any stockholder of a corporation of this State
who holds shares of stock on the date of the making of a demand pursuant to
subsection (d) of this section with respect to such shares, who continuously
holds such shares through the effective date of the merger or consolidation, who
has otherwise complied with subsection (d) of this section and who has neither
voted in favor of the merger or consolidation nor consented thereto in writing
pursuant to sec.228 of this title shall be entitled to an appraisal by the Court
of Chancery of the fair value of the stockholder's shares of stock under the
circumstances described in subsections (b) and (c) of this section. As used in
this section, the word "stockholder" means a holder of record of stock in a
stock corporation and also a member of record of a nonstock corporation; the
words "stock" and "share" mean and include what is ordinarily meant by those
words and also membership or membership interest of a member of a nonstock
corporation; and the words "depository receipt" mean a receipt or other
instrument issued by a depository representing an interest in one or more
shares, or fractions thereof, solely of stock of a corporation, which stock is
deposited with the depository.

     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec.251 (other than a merger effected pursuant to sec.251
(g) of this title), sec.252, sec.254, sec.257, sec.258, sec.263 or sec.264 of
this title:

          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving corporation
     as provided in subsection (f) of sec.251 of this title.

          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     Sections251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:

             a. Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof;

             b. Shares of stock of any other corporation, or depository receipts
        in respect thereof, which shares of stock (or depository receipts in
        respect thereof) or depository receipts at the effective date of the
        merger or consolidation will be either listed on a national securities
        exchange or designated as a national market system security on an
        interdealer quotation system by the National Association of Securities
        Dealers, Inc. or held of record by more than 2,000 holders;

             c. Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs a. and b. of this
        paragraph; or

             d. Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs a., b. and c. of this
        paragraph.

          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec.253 of this title is not owned by the
     parent corporation immediately prior to the merger, appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.

                                       E-1
<PAGE>   237

     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

     (d) Appraisal rights shall be perfected as follows:

          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsections (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of such
     stockholder's shares shall deliver to the corporation, before the taking of
     the vote on the merger or consolidation, a written demand for appraisal of
     such stockholder's shares. Such demand will be sufficient if it reasonably
     informs the corporation of the identity of the stockholder and that the
     stockholder intends thereby to demand the appraisal of such stockholder's
     shares. A proxy or vote against the merger or consolidation shall not
     constitute such a demand. A stockholder electing to take such action must
     do so by a separate written demand as herein provided. Within 10 days after
     the effective date of such merger or consolidation, the surviving or
     resulting corporation shall notify each stockholder of each constituent
     corporation who has complied with this subsection and has not voted in
     favor of or consented to the merger or consolidation of the date that the
     merger or consolidation has become effective; or

          (2) If the merger or consolidation was approved pursuant to sec.228 or
     sec.253 of this title, each constituent corporation, either before the
     effective date of the merger or consolidation or within ten days
     thereafter, shall notify each of the holders of any class or series of
     stock of such constituent corporation who are entitled to appraisal rights
     of the approval of the merger or consolidation and that appraisal rights
     are available for any or all shares of such class or series of stock of
     such constituent corporation, and shall include in such notice a copy of
     this section; provided that, if the notice is given on or after the
     effective date of the merger or consolidation, such notice shall be given
     by the surviving or resulting corporation to all such holders of any class
     or series of stock of a constituent corporation that are entitled to
     appraisal rights. Such notice may, and, if given on or after the effective
     date of the merger or consolidation, shall, also notify such stockholders
     of the effective date of the merger or consolidation. Any stockholder
     entitled to appraisal rights may, within 20 days after the date of mailing
     of such notice, demand in writing from the surviving or resulting
     corporation the appraisal of such holder's shares. Such demand will be
     sufficient if it reasonably informs the corporation of the identity of the
     stockholder and that the stockholder intends thereby to demand the
     appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each such constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the holders
     of any class or series of stock of such constituent corporation that are
     entitled to appraisal rights of the effective date of the merger or
     consolidation or (ii) the surviving or resulting corporation shall send
     such a second notice to all such holders on or within 10 days after such
     effective date; provided, however, that if such second notice is sent more
     than 20 days following the sending of the first notice, such second notice
     need only be sent to each stockholder who is entitled to appraisal rights
     and who has demanded appraisal of such holder's shares in accordance with
     this subsection. An affidavit of the secretary or assistant secretary or of
     the transfer agent of the corporation that is required to give either
     notice that such notice has been given shall, in the absence of fraud, be
     prima facie evidence of the facts stated therein. For purposes of
     determining the stockholders entitled to receive either notice, each
     constituent corporation may fix, in advance, a record date that shall be
     not more than 10 days prior to the date the notice is given, provided, that
     if the notice is given on or after the effective date of the

                                       E-2
<PAGE>   238

     merger or consolidation, the record date shall be such effective date. If
     no record date is fixed and the notice is given prior to the effective
     date, the record date shall be the close of business on the day next
     preceding the day on which the notice is given.

     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw such stockholder's demand for appraisal and to accept the terms offered
upon the merger or consolidation. Within 120 days after the effective date of
the merger or consolidation, any stockholder who has complied with the
requirements of subsections (a) and (d) hereof, upon written request, shall be
entitled to receive from the corporation surviving the merger or resulting from
the consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which demands
for appraisal have been received and the aggregate number of holders of such
shares. Such written statement shall be mailed to the stockholder within 10 days
after such stockholder's written request for such a statement is received by the
surviving or resulting corporation or within 10 days after expiration of the
period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.

     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by one or more publications at
least one week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted
such stockholder's certificates of stock to the Register in Chancery, if such is
required, may participate fully in all proceedings until it is finally
determined that such stockholder is not entitled to appraisal rights under this
section.
                                       E-3
<PAGE>   239

     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation, either
within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
of Chancery shall be dismissed as to any stockholder without the approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just.

     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

                                VOTING AGREEMENT

     VOTING AGREEMENT, dated as of May 14, 2000 (this "Agreement"), by the
executive officers identified on Schedule A hereto (each, a "Stockholder" and
collectively, the "Stockholders") of The Pioneer Group, Inc., a company
organized under the laws of the state of Delaware (the "Company"), to and for
the benefit of UniCredito Italiano S.p.A, a company organized under the laws of
the Republic of Italy ("Parent").

     WHEREAS, as of the date hereof, each of the Stockholders owns of record and
beneficially or has the power to vote the number of shares of the Company's
common stock, par value $.10 per share (the "Company Common Stock"), set forth
opposite such Stockholder's name on Schedule A hereto (such shares, together
with any shares of Company Common Stock acquired by the Stockholders prior to
the termination of this Agreement being referred to herein as the "Shares");

     WHEREAS, concurrently with the execution of this Agreement, Parent and the
Company are entering into an Agreement and Plan of Merger, dated as of the date
hereof (the "Merger Agreement"; capitalized terms used and not otherwise defined
herein shall have the respective meanings assigned to them in the Merger
Agreement), pursuant to which, upon the terms and subject to the conditions
thereof, a wholly owned subsidiary of Parent (the "Purchaser") will be merged
with and into the Company (the "Merger"); and

     WHEREAS, as a condition to the willingness of Parent and the Company to
enter into the Merger Agreement, Parent has requested the Stockholders to agree,
and in order to induce Parent to enter into the Merger Agreement, the
Stockholders are willing to agree to vote in favor of adopting the Merger
Agreement and approving the Merger, upon the terms and subject to the conditions
set forth herein.

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements contained herein, and intending to be legally bound hereby, the
parties hereby agree, severally and not jointly, as follows:

     Section 1.  Voting of Shares.  Until the termination of this Agreement in
accordance with the terms hereof, each Stockholder hereby agrees that, at the
Company Stockholders' Meeting or any other meeting of the stockholders of the
Company, however called, and in any action by written consent of the
stockholders of the Company, each Stockholder will vote all of his Shares that
such Stockholder is entitled to vote at such meeting or action (a) in favor of
adoption of the Merger Agreement and approval of the Merger and the other
transactions contemplated by the Merger Agreement, (b) against any action or
agreement that Parent has advised the Stockholder would result in a breach of
any covenant, representation or warranty or and other obligation or agreement of
the Company under the Merger Agreement (subject to the Company's rights under
Section 5.5 of the Merger Agreement) and (c) in favor of any other matter
necessary to consummate the transactions contemplated by the Merger Agreement
that is subject to approval of the Stockholders. Except as set forth in clauses
(a), (b) and (c) of the immediately preceding sentence, the Stockholder shall
not be restricted from voting in favor of, against or abstaining with respect to
any other matter presented to the Stockholders of the Company. In addition, each
Stockholder agrees that he/she will, upon request by Parent, furnish written
confirmation, in form and substance reasonably acceptable to Parent, of such
Stockholder's vote in favor of the Merger Agreement and the Merger. Each
Stockholder acknowledges receipt and review of a copy of the Merger Agreement.

     Section 2.  Proxy.  Each Stockholder, by this Agreement, does hereby
constitute and appoint Messrs. Pietro Modiano and Fabio Innocenzi, and each of
them acting individually, or any nominee of either of such individuals, with
full power of substitution, as such Stockholder's irrevocable proxy and
attorney-in-fact to vote the Shares as indicated in Section 1 in the event such
Stockholder fails to comply with his obligations under such section. Each
Stockholder intends this proxy to be irrevocable and coupled

                                       F-1
<PAGE>   241

with an interest and will take such further action and execute such other
instruments as may be necessary to effectuate the intent of this proxy and
hereby revokes any proxy previously granted by him with respect his Shares.

     Section 3.  Transfer of Shares.  Each Stockholder severally and not jointly
represents and warrants that he/she has no present intention of taking action
to, prior to the termination of this Agreement in accordance with the terms
hereof, directly or indirectly, (a) to sell, assign, transfer, pledge, encumber
or otherwise dispose of any of the Shares, (b) deposit any of the Shares into a
voting trust or enter into a voting agreement or arrangement with respect to the
Shares or grant any proxy or power of attorney with respect thereto which is
inconsistent with this Agreement or (c) enter into any contract, option or other
arrangement or undertaking with respect to the direct or indirect sale,
assignment, transfer (including by operation of law) or other disposition of any
Shares.

     Section 4.  Representations and Warranties of Stockholder.  Each
Stockholder severally and not jointly hereby represents and warrants to Parent
with respect to himself and the ownership of his Shares as follows:

          (a) Such Stockholder has all legal capacity to execute and deliver
     this Agreement and to consummate the transactions contemplated hereby.

          (b) Such Stockholder is the record or beneficial owner of, or has the
     power to vote, his Shares and, if such Stockholder is the beneficial owner
     of such Shares, he owns such Shares free and clear of any liens, claims,
     charges, encumbrances or voting agreements and commitments of every kind,
     other than this Agreement, except as set forth in the Merger Agreement or
     the Disclosure Schedules.

          (c) This Agreement has been duly executed and delivered by such
     Stockholder.

          (d) This Agreement constitutes the valid and binding agreement of such
     Stockholder, enforceable against such Stockholder in accordance with its
     terms, except as such enforceability may be limited by bankruptcy,
     insolvency or other similar requirements of law affecting the enforcement
     of creditor's rights generally and by general principles of equity.

     Section 5.  No Solicitation.  No Stockholder shall take, directly or
indirectly, (nor shall a Stockholder authorize or permit his representatives, or
to the extent within the Stockholder's control, his affiliates to take) any
action to (i) encourage (including by way of furnishing nonpublic information),
solicit, initiate or facilitate any Acquisition Proposal, (ii) enter into any
letter of intent, term sheet or other agreement with respect to any Acquisition
Proposal or (iii) participate in any way in discussions or negotiations with, or
furnish any information to, any person in connection with, or take any other
action to facilitate any inquiries or the making of any proposal that
constitutes, or could reasonably be expected to lead to, any Acquisition
Proposal; provided, however, that nothing in this Section 5 shall prevent the
Stockholder, in his capacity as a director or executive officer of the Company,
from engaging in any activity permitted pursuant to Section 5.5 of the Merger
Agreement. The Stockholder shall immediately cease and cause to be terminated
all discussions or negotiations commenced prior to the date hereof with respect
to any Acquisition Proposal. From and after the date of the execution of this
Agreement, the Stockholder will as promptly as practicable communicate to Parent
orally and in writing any inquiry received by him relating to any Acquisition
Proposal and the material terms of any proposal or inquiry, including the
identity of the person and its affiliates making the same, that he may receive
in respect of any such negotiations or discussions being sought to be initiated
with the Company. The Stockholder shall (i) keep Parent fully informed on a
prompt basis with respect to any developments with respect to the foregoing and
(ii) provide to Parent as soon as practicable after receipt or delivery thereof
with copies of all correspondence and other written material sent or provided to
the Company from any Third Party in connection with any Acquisition Proposal. In
addition, each of the Stockholders of the Company agrees that he will not enter
into any employment, consulting or similar arrangement (or participate in any
negotiations or discussions concerning such arrangements) with any person that
has made an Acquisition Proposal (other than Parent or its affiliates) prior to
termination of this Agreement in accordance with its terms.

                                       F-2
<PAGE>   242

     Section 6.  Termination.  This Agreement shall terminate upon the earlier
to occur of (i) the Effective Time or (ii) the termination of the Merger
Agreement in accordance with the terms thereof; provided that the provisions of
Section 7 of this Agreement shall survive any termination of this Agreement; and
provided further that no such termination shall relieve any party of liability
for a breach hereof prior to termination.

     Section 7.  Specific Performance.  The Stockholders acknowledge that Parent
believes that irreparable damage would occur in the event any provision of this
Agreement was not performed in accordance with the terms hereof and that the
parties may be entitled to specific performance of the terms hereof, in addition
to any other remedy at law or in equity.

     Section 8.  Miscellaneous.

     (a) All notices, requests, claims, demands and other communications
hereunder shall be in writing and shall be given or made (and shall be deemed to
have been duly made or given upon receipt) by delivery in person, by facsimile,
by courier service or by registered or certified mail (postage prepaid, return
receipt requested) to the respective parties at the following addresses (or at
such other address for a party as shall be specified in a notice given in
accordance herewith):
