                          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."



                                      -1-
<PAGE>   9


                    (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 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

                        (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



                                      -3-
<PAGE>   11

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 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



                                      -4-
<PAGE>   12

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



                                      -5-
<PAGE>   13

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.

                                   ARTICLE 2

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 materially impair the ability of the Parent and the
Purchaser to perform their obligations hereunder.

certificates and other documents delivered in connection herewith, the term
"Parent's knowledge" or "Parent's best knowledge" or similar phrases shall mean

knowledge that such person would have had if he or she had made reasonable
inquiry.

                                   ARTICLE 3
                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         The Company represents and warrants to the Parent and the Purchaser,
except as set forth on a disclosure schedule previously delivered to the Parent
(the "Disclosure Schedule") with respect to any representation or warranty set
forth below, as of the date hereof and as of the Closing Date as follows:

                3.1 ORGANIZATION AND QUALIFICATION. The Company is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Delaware and has all requisite corporate power and authority to carry
on its business as it is now being conducted. The Company is duly qualified as a
foreign corporation to do business, and is in good standing, in each
jurisdiction where the character of its properties owned or leased or the nature
of its activities makes such qualification necessary, except for failures to be
so qualified or in good standing which would not, individually or in the
aggregate, reasonably be expected to have a Company Material Adverse Effect (as
defined below). Copies of the Certificate of Incorporation and By-Laws of the
Company have heretofore been delivered to the Parent and the Purchaser and such
copies are accurate and complete as of the date hereof. For purposes of this
Agreement, "Company Material Adverse Effect" shall mean any change, effect or
circumstance that is materially adverse to the assets, the financial condition,
business or operations of the Company and its Subsidiaries (as defined in
Section 3.2) taken as a whole (other than changes that result from economic
factors affecting the economy as a whole or changes that are the result of
factors generally affecting the mutual fund industry); provided, that (i)
Company Material Adverse Effect shall not include any adverse change, effect or
circumstance arising out of or resulting from actions contemplated by the
parties in connection with this Agreement or that is



                                      -9-
<PAGE>   17

attributable to the announcement or performance of this Agreement or the
transactions contemplated by this Agreement other than the Distribution and (ii)
any adverse change in the Company's stock price shall not be taken into account
in determining whether there has been a Company Material Adverse Effect.

                3.2 SUBSIDIARIES. The only direct or indirect subsidiaries of
the Company (the "Subsidiaries") are those named in Exhibit 21 to the Company's
Annual Report on Form 10-K for the Fiscal Year ended December 31, 1999 as filed
with the Commission and heretofore delivered to the Parent or as otherwise set
forth in the Disclosure Schedule or the Commission Filings (as defined in
Section 3.6). The term "Continuing Subsidiary" shall mean any Subsidiary of the
Company that is not being transferred to Harbor Global in accordance with
Article 8 of this Agreement and pursuant to the Distribution Agreement.

         No securities of any of the Continuing Subsidiaries are or may become
required to be issued by reason of any options, warrants, scrip, rights to
subscribe to, calls or commitments of any character whatsoever relating to, or
securities or rights convertible into or exchangeable for, shares of any capital
stock of any Continuing Subsidiary. There are no contracts, commitments,
understandings or arrangements by which any Continuing Subsidiary is bound to
issue additional shares or purchase shares of its capital stock (or its
equivalent) or securities convertible into or exchangeable for such shares or
similar interests and there are no agreements or understandings to which the
Company or any of its Continuous Subsidiaries is a party with respect to voting
the capital stock (or its equivalent) of any Subsidiary. All of such shares or
similar interests so owned by the Company are validly issued, fully paid and
non-assessable and are owned by the Company free and clear of any claim, lien,
encumbrance or agreement of any kind with respect thereto.

         Each Continuing Subsidiary is a corporation or other entity duly
organized, validly existing and in good standing under the laws of its
jurisdiction of incorporation or organization and has the requisite power and
authority to carry on its business as it is now being conducted. Each Continuing
Subsidiary is duly qualified as a foreign corporation to do business, and is in
good standing, in each jurisdiction where the character of its properties owned
or leased or the nature of its activities makes such qualification necessary,
except for failures to be so qualified or in good standing that would not,
individually or in the aggregate, reasonably be expected to have a Company
Material Adverse Effect. Copies of the charter documents and by-laws of each
Continuing Subsidiary have heretofore been made available to the Parent and are
accurate and complete as of the date hereof.

         Except as disclosed in Section 3.2 of the Disclosure Schedule or the
Commission Filings filed prior to the date hereof, the Company does not directly
or indirectly own any equity or similar interest in, or any interest convertible
into or exchangeable or exercisable for, any equity or similar interest in, any
other corporation, partnership, joint venture or other business association or
entity.

                3.3 CAPITALIZATION. The authorized capital stock of the Company
consists of 60,000,000 shares of Common Stock, $0.10 par value. As of the date
of this Agreement:

                    (a) 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

Subsidiaries, 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

authorization, consent or approval of, any domestic or foreign public body or
authority or any governmental or non-governmental self-regulatory organization
or agency is necessary for the consummation by the Company of the transactions
contemplated by this Agreement, unless the failure to give such notices, make
such filings, or obtain such authorizations, consents or approvals would not,
individually or in the aggregate, materially impair the ability of the



                                      -12-
<PAGE>   20

Company to perform its obligations hereunder and would not, individually or in
the aggregate, reasonably be expected to have a Company Material Adverse Effect.

                3.6 COMMISSION FILINGS.

                    (a) The Company and its Continuing Subsidiaries have filed

                3.7 LITIGATION. There are no actions, suits, proceedings or
investigations pending or, to the best knowledge of the Company, threatened
against the Company or any of its Continuing Subsidiaries, nor is the Company or
any of its Continuing Subsidiaries subject to any order, judgment, writ,
injunction or decree, except in either case for matters that, individually or in
the aggregate, would not reasonably be expected to have a Company Material
Adverse Effect and would not materially adversely affect the Company's ability
to perform its obligations under this Agreement.

                3.8 CHANGES. Except as specifically set forth in this Agreement,
in Section 3.8 of the Disclosure Schedule or as disclosed in the Commission

with past practice, (b) there has not been any event, change or effect which,
individually or in the aggregate, has resulted in a Company Material Adverse
Effect, and (c) neither the Company nor any of its Continuing Subsidiaries has
taken any action that, if taken after the date of this Agreement, would
constitute a breach of any of the covenants set forth in Section 4.1(b), Section
8.2 or Section 8.3.

                3.9 TRANSACTIONS WITH AFFILIATES. Except as disclosed in the
Commission Filings filed prior to the date hereof, since January 1, 1997,
neither the Company nor any of its Continuing Subsidiaries has entered into any
transaction with any current director or officer of the Company or any
Continuing Subsidiary or any transaction which would be subject to proxy
statement disclosure under the Exchange Act pursuant to the requirements of Item

                3.10 ENVIRONMENTAL MATTERS.

                    (a) The Company and the Continuing Subsidiaries have
complied in all material respects with all applicable Environmental Laws (as
defined below). There is no civil or criminal litigation, written notice of
violation, administrative proceeding or investigation, inquiry or information
request by any court, arbitration tribunal, administrative agency or commission
or other governmental or regulatory authority or agency (a "Governmental
Entity") pending or, to the knowledge of the Company, threatened relating to any
Environmental Law involving the Company or any of its Continuing Subsidiaries.
For purposes of this Agreement, "Environmental Law" means any foreign, federal,
state or local law, statute, rule or regulation or the common law relating to
the environment or occupational health and safety, including without limitation,
any statute, regulation or order pertaining to (i) treatment, storage, disposal,
generation or transportation of industrial, toxic or hazardous substances or
solid or hazardous waste; (ii) air, water and noise pollution; (iii) groundwater
and soil contamination; (iv) the release or threatened release into the
environment of industrial, toxic or hazardous substances, or solid or hazardous
waste, including without limitation emissions, discharges, injections, spills,
escapes or dumping of pollutants, contaminants or chemicals; (v) the protection
of wildlife,



                                      -14-
<PAGE>   22

marine 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.


                                      -15-
<PAGE>   23

                    (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 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.

                    (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.


                                      -17-
<PAGE>   25

                    (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, 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



                                      -18-
<PAGE>   26

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.

                    (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

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

("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 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.

                    (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



                                      -22-
<PAGE>   30

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.

                    (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


                                      -23-
<PAGE>   31

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



                                      -24-
<PAGE>   32

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 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;



                                      -25-
<PAGE>   33

                    (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
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.

                    (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 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

present relationships and good will of the Company and its Continuing

information to, any corporation, partnership, person or other entity or group
other than the Parent, the Purchaser or another affiliate of the Parent (a
"Third Party") and other than in connection with this Agreement, concerning (or
concerning the business of the Company or any Continuing Subsidiary in
connection with) any tender offer for more than 20% of the Shares on a

the



                                      -33-
<PAGE>   41

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 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



                                      -34-
<PAGE>   42

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 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



                                      -35-
<PAGE>   43

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 "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



                                      -36-

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.

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

     [UniCredito Italiano Logo]                        [Pioneer Logo]


                 UNICREDITO ITALIANO GROUP ANNOUNCES ACQUISITION
                   OF THE PIONEER GROUP, INC. FOR $1.2 BILLION
 DEAL ENABLES STRATEGIC EXPANSION FOR UNICREDITO ITALIANO GROUP INTO U.S. MARKET


Boston, MA (May 15, 2000) - The Pioneer Group, Inc. (NASDAQ: PIOG) and
UniCredito Italiano Group (CRDI.MI), Italy's second largest banking group, today
announced a definitive agreement under which UniCredito Italiano Group
("UniCredito") will purchase all of the outstanding shares of The Pioneer Group,
Inc. ("Pioneer") for $43.50 per share in cash. In the transaction, UniCredito
Italiano Group will acquire all of Pioneer's global investment management
businesses, including operations in the U.S., Germany, Ireland, Eastern Europe
and Asia. Prior to the close of its transaction with UniCredito, Pioneer will
distribute to its shareholders 100% of the company's ownership interest in its
remaining assets, including its Russian financial services operation, its
natural resource businesses, and its interests in venture capital and real
estate.

The transaction has an equity market value of approximately $1.2 billion based
upon the fully diluted Pioneer common shares and options currently outstanding.
Upon completion of the transaction, Pioneer and EuroPlus Research and Management
("EuroPlus"), UniCredito's existing asset management division, with operations
in Dublin and Milan, will combine to form a powerful global investment company
with assets under management of over $100 billion.

The newly created Pioneer Global Asset Management, incorporated in Italy, will
serve as the holding company for all global investment management businesses and
will conduct its business worldwide under the Pioneer name.

Mr. John F. Cogan, Jr., President and Chief Executive Officer of The Pioneer
Group, Inc. said, "We are very pleased to be joining an organization with the
reputation and breadth of UniCredito. UniCredito's EuroPlus division has
approximately $80 billion of assets under management. This transaction provides
Pioneer shareholders with a premium on their investment and positions the
combined company to play a leadership role in asset management throughout Europe
and within the United States."

"UniCredito and Pioneer have complementary business platforms," Mr. Cogan
continued. "We have similar investment philosophies, employing a bottom up,
research-based approach to investment decisions. UniCredito has a strong
distribution channel in Italy and offers fixed income as well as equity
investment products. Pioneer has strong distribution channels in the U.S. and
Germany with a seventy-two year history of equity investing. Both Pioneer and
UniCredito clients will benefit from an expanded product line. Pioneer's
employees can look forward to expanded career opportunities in a truly global
investment management business. We eagerly anticipate working with UniCredito to
capture the benefits of this combination for our customers and our employees."

Mr. Pietro Modiano, Head of Treasury, Investment Banking and Asset Management of
UniCredito Italiano Group said, "The combination of Pioneer and EuroPlus will
create one of the few asset management groups with strong bases in both the U.S.
and Europe, and a presence in eight countries. We see significant opportunity to
leverage Pioneer's and EuroPlus's product and distribution capabilities in
Europe and the U.S. Pioneer will benefit from a strong commitment of UniCredito
to realize fully what we perceive to be enormous potential of our combined asset
management businesses both in the U.S. market and globally."

"We believe that, with the inclusion of Pioneer, we will continue the success
that we have had in Europe with EuroPlus. At EuroPlus we have been able to
capture the asset management opportunities of one of Europe's fastest growing
markets while enjoying strong economic returns."

MANAGEMENT

Mr. Pietro Modiano of UniCredito will be the Chairman of the newly created
Pioneer Global Asset Management, based in Italy. Mr. John F. Cogan, Jr. will
become Deputy Chairman of Pioneer Global Asset Management and will also be
non-executive Chairman of Pioneer U.S., whose U.S. headquarters will remain in
Boston. Mr. Fabio Innocenzi, currently Chief Executive Officer of EuroPlus, will
become Chief Executive Officer of Pioneer Global Asset Management and Executive
Vice Chairman of Pioneer U.S. Mr. David D. Tripple, currently President of
Pioneer Investment Management, will become Chief Executive Officer of Pioneer
U.S.

TIMING AND APPROVALS

Completion of the acquisition is subject to, among other things, approval by
Pioneer's shareholders, Pioneer's mutual fund board of trustees and fund
shareholders, and various regulatory agencies. The transaction is expected to
close in the third quarter of 2000.

DISTRIBUTION TO SHAREHOLDERS OF PIONEER'S REMAINING OPERATIONS

Immediately prior to the close of the transaction, Pioneer's other assets -
natural resources and other operations outside of the core investment management
business - will be spun-off into a newly organized limited duration company to
be named Harbor Global Company, Ltd. ("Harbor"). Pioneer shareholders will
receive certificates of ownership in the new company. The new company will
operate the businesses, with the purpose of ultimately liquidating the assets
and distributing the proceeds within five years.

Mr. Stephen G. Kasnet, currently President of Pioneer Global Investments will
become president of Harbor. The Board of Directors of Harbor will consist of
three members of Pioneer's current board of directors, Mr. John D. Curtin Jr.,
Mr. W. Reid Sanders and Mr. John H. Valentine.
