                    THE PIONEER GROUP, INC. AND SUBSIDIARIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
                               SEPTEMBER 30, 1999

NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The accounting and reporting policies of the Company conform to generally
accepted accounting principles. The Company has not changed any of its principal
accounting policies from those stated in the Annual Report on Form 10-K for the
year ended December 31, 1998. The footnotes to the financial statements reported
in the 1998 Annual Report on Form 10-K are incorporated herein by reference,
except to the extent that any such footnote is updated by the following:

     Certain reclassifications have been made to the accompanying 1998
consolidated financial statements to conform with the 1999 presentation.

     During the first quarter of 1999, the Company adopted the provisions of the
American Institute of Certified Public Accountants' (the "AICPA") SOP 98-5,
"Reporting on the Costs of Start-Up Activities." The new standard requires that
entities expense costs of start-up activities as those costs are incurred. The
Company had capitalized certain pre-operating costs in connection with its
natural resource operations, and had capitalized organizational costs associated
with its financial services operations. Adoption of this statement resulted in a
write-off of unamortized start-up costs of $12.1 million, or $0.47 per share,
which is reflected in the accompanying consolidated financial statements as a
change in accounting principle. The amount of pro forma net income in the first
quarter of 1998 did not differ materially from the amount reported after giving
effect to the change in accounting principle.

     In April 1999, the Company reached agreement with Nationwide Global
Holdings, Inc. to sell newly issued shares of its Polish pension company
subsidiary resulting in a 30% interest for $20 million. As a result of the
transaction, which received Polish regulatory approval on June 9, 1999, the
Company recognized a gain of approximately $12 million which was reflected as a
credit to stockholders' equity in the second quarter of 1999. In addition, the
Company deconsolidated the Polish pension company as control is shared with
Nationwide and is accounting for its investment in the pension company under the
equity method retroactive to January 1, 1999. The effect of this transaction is
reflected in the accompanying Consolidated Statements of Cash Flows as
deconsolidation of pension company subsidiary.

     Income taxes paid were $23,290,000 and $14,794,000 for the nine months
ended September 30, 1999, and September 30, 1998, respectively. In addition,
interest paid was $7,223,000 for the nine months ended September 30, 1999, and
$8,167,000 for the nine months ended September 30, 1998.

NOTE 2 -- EARNINGS PER SHARE

     The following table details the calculation of basic and diluted earnings
per share ("EPS"). Basic EPS is computed by dividing reported earnings available
to stockholders by weighted average shares outstanding not including
contingently issuable shares. Diluted EPS includes the effect of the
contingently issuable shares and other common stock equivalents, if not
antidilutive.

     The Company adopted SFAS 130, "Reporting Comprehensive Income" in the first
quarter of 1998. SFAS 130 establishes standards for the reporting of
comprehensive income and its components. Comprehensive income, as defined,
includes all changes in equity during a period from non-owner sources. The
Company's foreign currency translation adjustments, which are excluded from net
income, are included in comprehensive income. The following table reports
comprehensive income for the nine months ended September 30, 1999 and 1998.

     At September 30, 1999, the Company had $36 million of debt attributable to
its discontinued gold mining operations. Scheduled debt service for the
remainder of 1999 is expected to aggregate $2.2 million, of which $1.8 million
represents principal payments.

     In June 1996, the Company entered into an agreement with a syndicate of
commercial banks for a senior credit facility, which has been amended from time
to time (the "Credit Facility"). Under the Credit Facility, the Company may
borrow up to $55 million for general corporate purposes. The Credit Facility
contains restrictions that limit, among other things, encumbrances on the assets
of the Company's domestic mutual fund subsidiaries and certain mergers and sales
of assets. Additionally, the Credit Facility requires that the Company meet
certain financial covenants including covenants that require the Company to
maintain certain minimum ratios with respect to debt to cash flow and interest
payments to cash flow and a minimum tangible net worth, all as defined in the
Credit Facility. The Company is in compliance with all applicable covenants. At
September 30, 1999, the Company had borrowed $40 million under the Credit
Facility.

     As of September 30, 1999, the Company had two five-year interest rate swap
agreements with a member of the Company's banking syndicate which has
effectively fixed the interest rate on notional amounts totaling $60 million.
Under these agreements, the Company will pay the bank a weighted average fixed
rate of 6.90%, plus the applicable margin of 2.25% on the notional principal.
The bank will pay the Company interest on the notional principal at the current
variable rate stated under the Credit Facility. The Company has incurred
approximately $955,000 and $876,000 of interest expense on these swap agreements
during the nine months ended September 30, 1999 and September 30, 1998,
respectively. During June 1999, the Company unwound $40 million of overhedged
swaps and recognized $426,000 of income on the transaction. At September 30,
1999, the Company had $20 million of overhedged swaps and recognized
approximately $191,000 of expense during the nine months ended September 30,
1999, in accordance with generally accepted accounting principles, related to
these swaps. At September 30, 1999, the fair value of the swaps was ($959,000),
compared to a book value of ($293,000). If the Company were to terminate these
agreements, it would be required to pay an amount approximating fair value.

     In 1997, the Company entered into an agreement (the "Note Agreement") with
a commercial lender pursuant to which the Company issued to the lender Senior
Notes in the aggregate principal amount of $20 million. The Senior Notes, which
bear interest at the rate of 8.95% per annum, have a maturity of seven years.
The restrictions and financial covenants under the Note Agreement are
substantially similar to the amended restrictions and financial covenants under
the Credit Facility.

     For the nine months ended September 30, 1999 and September 30, 1998 the
weighted average interest rate on the borrowings under the Credit Facility and
Note Agreement was 9.41% and 7.93%, respectively.

NOTE 6 -- DISCONTINUED OPERATIONS

     In the third quarter of 1998, the Company decided to liquidate its Russian
banking operations. Accordingly, the operating results for the bank have been

     In the second quarter of 1999, the Company reflected the gold mining
segment as a discontinued operation. Accordingly, the operating results for gold
mining have been segregated from the results of continuing operations and
reported as a separate line on the consolidated statements of operations for all
periods presented. Losses from discontinued gold mining operations in the nine
months ended September 30, 1999 include $53.6 million from the estimated loss on
the disposition of the gold mining segment, principally from the impairment of
the long-lived assets of Teberebie Goldfields Limited, the Company's 90% owned
subsidiary. The above referenced losses are management's best estimates of the
costs of winding down the gold mining operations. The Company, however, may
record gains or incur additional losses in either a sales transaction or closure
scenario as details, timing and other events unfold. There can be no assurance
that the Company can successfully negotiate a sales transaction and consummate
that transaction or close the mine in accordance with management's estimates. In
addition, the Company disposed of its powdered metals business. Losses included
$0.9 million from the loss on the disposition of the powdered metals business.
The following is an unaudited summary of the loss from operations of the gold
mining and powdered metals segments for the nine months ended September 30, 1999
and 1998, respectively:

ITEM 2.  MANAGEMENT'S DISCUSSION & ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

                                    OVERVIEW

     The consolidated financial statements of The Pioneer Group, Inc. (the
"Company") include the Company's three strategic business units. Pioneer
Investment Management includes the investment management, marketing,
distribution and servicing of the Company's mutual funds based in the United
States and offshore funds based in Ireland. This business unit also provides
investment management services for institutional investors. Pioneer
International Financial Services includes the Company's investment management
and financial services businesses in Poland, the Czech Republic, Russia and
India. Pioneer Global Investments includes the Company's worldwide venture
capital, real estate and timber operations. The Company is in the process of
disposing its gold mining operations and as such is reporting those results as
discontinued operations. Management's Discussion and Analysis of Financial
Condition and Results of Operations is presented in four sections: Results of
Operations, Liquidity and Capital Resources-General, Future Operating Results
and Year 2000.

                             RESULTS OF OPERATIONS

                            CONSOLIDATED OPERATIONS

                         PIONEER INVESTMENT MANAGEMENT

     Pioneer Investment Management ("PIM") recorded third quarter 1999 net
income of $8.9 million compared to third quarter 1998 net income of $10.8
million, including $5.5 million of operating income and a gain of $5.3 million
associated with the sale of Class B share rights. PIM recorded net income of
$26.4 million for the nine months ended September 30, 1999, compared to $29.9
million for the nine months ended September 30, 1998. Excluding the one-time
gain, PIM's net income increased by $3.4 million and $1.8 million for the third
quarter and nine months ended September 30, 1999, respectively.

     PIM's assets under management at September 30, 1999 were approximately
$22.3 billion compared to approximately $23.0 billion at December 31, 1998. In
the third quarter of 1999, sales of U.S. registered mutual funds (including
reinvested dividends) were approximately $0.8 billion, 13% below sales in the
third quarter of 1998. Net redemptions were approximately $0.1 billion, compared
to net sales of approximately $0.3 billion in the third quarter of 1998. For the
nine months ended September 30, 1999, sales of U.S. registered mutual funds
(including reinvested dividends) were approximately $2.9 billion, 6% below sales
in the comparable 1998 period. Net redemptions were approximately $0.1 billion,
compared to net sales of approximately $1.3 billion in the first nine months of
1998.

     Since October 1998, the Company has sold each month at a premium additional
rights arising from sales of Class B shares. In consideration for the sale, the
Company relinquishes its rights to receive future distribution fees and certain
sales charges. As a result, distribution fees and expenses associated with the
amortization of Class B Share dealer advances have decreased significantly in
1999. In the third quarter of 1998, distribution fees related to Class B and C
shares were $4.8 million and amortization expenses were $3.8 million, compared
to fees of $1.1 million and expenses of $0.5 million in the third quarter of
1999. In the first nine months of 1998, distribution fees were $13.6 million and
amortization expenses were $10.1 million, compared to fees of $4.2 million and
expenses of $1.6 million in the first nine months of 1999.

     Revenues of $51.1 million in the third quarter of 1999 increased by $1.6
million, excluding the one-time gain associated with the B-Share rights sale.
Management fee revenues of $35.1 million increased by $2.8 million, as average
assets under management for the quarter increased by $2.0 billion to $23.5
billion. Revenues from underwriting commissions, distribution fees, and
shareholder servicing fees decreased by $2.4 million to $13.2 million, as
increased shareholder service fees partially offset lower distribution fees.

     Excluding the B-Share rights sale, revenues of $152.1 million in the first
nine months of 1999 increased by $1.0 million. Management fee revenues of $102.8
million increased by $4.8 million, as average assets under management for the
nine months increased by $1.1 billion to $23.2 billion. Revenues from
underwriting commissions, distribution fees, and shareholder servicing fees
decreased by $5.1 million to $40.7 million, as increased shareholder service
fees partially offset lower distribution fees. All other revenues increased by
$1.3 million, principally from increased trustee fees on mutual fund retirement
accounts and higher interest income.

     Costs and expenses decreased by $3.3 million in the third quarter of 1999
to $37.4 million, principally from lower expenses associated with the
amortization of dealer advances. For the nine months ended September 30, 1999,
costs and expenses of $111.7 million decreased by $0.8 million. Excluding the
$8.5 million decrease in dealer advance amortization expenses overall expenses
increased by $7.7 million, resulting principally from higher payroll costs,
higher mutual fund distribution expenses and higher costs related to additional
office space.

     PIM's effective tax rate for the third quarters of both 1999 and 1998 were
36%. For the nine months ended September 30, 1999, PIM's effective tax rate was
34.7% compared to 36.2% in the first nine months of 1998. The decrease resulted
principally from a change in Massachusetts' tax law that provided certain tax
incentives to Massachusetts-based mutual fund companies which maintain and grow
their Massachusetts employee base.

                    PIONEER INTERNATIONAL FINANCIAL SERVICES

     During the third quarter of 1999, Pioneer International Financial Services
("PIFS") lost $3.6 million on revenues of $7.1 million compared to a loss of
$9.0 million on revenues of $4.4 million in the third quarter of 1998. A
substantial portion ($2.8 million) of the third quarter 1999 loss occurred in
Poland, $2.2 million of which related to the Company's pension subsidiary. In
line with the Company's expectations, the quarterly rate of loss declined as
start-up costs and advertising expenses wound down. In addition, the Company
only recorded 70% of the pension company's operating losses for the full third
quarter as opposed to recording 100% of the losses for most of the second
quarter. Most of PIFS' third quarter 1998 loss ($8.0 million) occurred in
Russia, $5.6 million of which related to a cost basis adjustment and the
write-off of uncollectible receivables of the Pioneer First Investment Fund.
During the nine months ended September 30, 1999, PIFS lost $12.8 million on
revenues of $21.9 million compared to a loss of $12.0 million on revenues of
$17.2 million in the nine months ended September 30, 1998. Most of the 1999 loss
($11.2 million) occurred in Poland and related to the Company's pension
subsidiary while most of the 1998 loss ($9.8 million) occurred in Russia and
related to the Pioneer First Investment Fund.

     In April 1999, the Company reached agreement with Nationwide Global
Holdings, Inc. ("Nationwide") to sell a 30% interest in the Company's Polish
pension subsidiary for $20 million. As a result of the transaction, which
received Polish regulatory approval in June 1999, the Company recognized a gain
of approximately $12 million which was reflected as a credit to stockholders'
equity in the second quarter. In addition, the Company has deconsolidated the
Polish pension company as control is shared with Nationwide and has accounted
for its

                                       15
<PAGE>   16

investment in the pension company under the equity method retroactive to January
1, 1999. The consolidation method of accounting was used during the fourth
quarter of 1998, when the pension company was formed.

                           PIONEER GLOBAL INVESTMENTS

     In the third quarter, Pioneer Global Investments lost $3.3 million on
revenues of $5.9 million compared to losses of $8.9 million on revenues of $3.9
million in the third quarter of 1998. The reduced losses included lower timber
losses of $3.6 million and lower venture capital losses of $2.7 million,
partially offset by higher real estate losses of $0.7 million.

     In the first nine months of 1999, Pioneer Global Investments lost $11.8
million on revenues of $11.5 million compared to losses of $17.7 million on
revenues of $8.4 million in the first nine months of 1998. Included in the $5.9
million reduction in losses were lower timber losses of $12.1 million which more
than offset the lower venture capital earnings of $4.8 million and higher real
estate losses of $1.4 million. The Company sold its U.S. venture capital
operations in the first quarter of 1999 resulting in a one-time loss of $3.4
million.

TIMBER BUSINESS

     The results of the timber business are substantially attributable to the
operations of Forest-Starma, the Company's indirect wholly owned subsidiary.
Forest-Starma, which harvests timber in the Khabarovsk Territory of Russia, has
developed a modern logging camp, including a harbor, from which it exports
timber to markets in the Pacific Rim.

     RESULTS OF OPERATIONS.  For the three and nine months ended September 30,
1999, the timber business lost $2.0 million and $4.7 million, respectively.
During the corresponding periods in 1998, the timber business lost $5.6 million
and $16.8 million, respectively. The decrease in losses was attributable
principally to higher prices and production, and lower interest expense
associated with an intercompany debt-to-equity conversion.

     TIMBER PRODUCTION AND SALES.  Production during the three and nine months
ended September 30, 1999, was 72,000 and 230,000 cubic meters, respectively.
This represents increases of 60% and 68%, respectively, compared with
corresponding periods in 1998. Production costs for the third quarter of 1999
were approximately $58 per cubic meter, including approximately $10 per cubic
meter of depreciation and amortization. Production costs were $87 per cubic
meter in the third quarter of 1998, including approximately $13 per cubic meter
of depreciation and amortization. During the three and nine months ended
September 30, 1999, Forest-Starma shipped 135,000 cubic meters and 234,000 cubic
meters of timber at an average realized price of $39 per cubic meter and $41 per
cubic meter, respectively. During the three and nine months ended September 30,
1998, Forest-Starma shipped 109,000 cubic meters and 191,000 cubic meters,
respectively, at average realized prices of $28 per cubic meter and $31 per
cubic meter, respectively. Production costs were $52 and $88 per cubic meter in
the nine months ended September 30, 1999 and September 30, 1998, including $10
and $13 per cubic meter of depreciation and amortization, respectively.

     THIRD-PARTY DEBT.  Forest-Starma had $5.6 million of external debt
outstanding at September 30, 1999. The Company is subject to recourse on this
borrowing. Scheduled third-party debt service for the remainder of the year is
expected to aggregate $0.9 million.

     RECENT DEVELOPMENTS.  The Company is continuing discussions with several
potential strategic partners as participants in its timber business.

                            DISCONTINUED OPERATIONS

     During the second quarter of 1999, the Company reflected the gold mining
segment as a discontinued operation. The gold mining segment consists of Pioneer
Goldfields Limited ("PGL"), and its 90%-owned Ghanaian operating subsidiary,
Teberebie Goldfields Limited ("TGL"), and Closed Joint-Stock Company "Tas-Yurjah
Mining Company" ("Tas-Yurjah"), the Company's majority owned (95%) Russian
subsidiary. The Company also reflected its powdered metals and Russian banking
operations as discontinued operations in the second quarter of 1999 and the
third quarter of 1998, respectively. The following table summarizes discontinued
operations for the three and nine months ended September 30, 1999 and September
30, 1998:

GOLD MINING

     In October 1998, the Company engaged the services of an investment banking
firm to sell PGL, including its African exploration rights and its ownership
interest in TGL. An offering document, which incorporated a new mine plan and
revised reserve estimates, was circulated in the second quarter of 1999 to a
select group of potential buyers. Several of these potential buyers began
conducting due diligence efforts during July. The Company is now conducting what
it believes to be final negotiations with potential purchasers.

     Whether or not the Company consummates a sale, it recently determined to
proceed with an orderly closure of the Teberebie mine. Mining operations will
cease by the end of the year and all processing activities will cease in the
first half of 2000. The Company believes it can complete the closure without
providing additional funding to TGL. Based on the foregoing, additional losses
from discontinued gold mining operations in the third quarter of 1999 were $42.8
million, principally related to the impairment of the long-lived assets of TGL.
The losses described above reflect management's estimates of the costs of
winding down the gold mining operations. The Company, however, may record gains
or incur additional losses in either a sales transaction or closure scenario as
details, timing, and other events unfold. There can be no assurance that the
Company can successfully negotiate a sales transaction and consummate that
transaction or close the mine in accordance with management's estimates.

     Losses from discontinued gold mining operations were $8.2 million in the
third quarter of 1998.

     Losses from discontinued gold mining operations during the first nine
months of 1999 were $72.3 million, including $18.7 million from operations and
$53.5 million from the estimated loss on the disposition of the gold mining
segment. Losses from discontinued gold mining operations in the first nine
months of 1998 were $15.1 million.

     The following summarizes the operations of TGL during the third quarter and
nine months ended September 30, 1999, compared to the third quarter and nine
months ended September 30, 1998.

     GOLD SALES.  Revenues decreased by $0.7 million to $17.1 million in the
third quarter of 1999 compared with 1998, as a $39 decrease in the average
realized price of gold to $264 per ounce was largely offset by a 6,400 ounce, or
11%, increase in gold shipments to 65,000 ounces. Revenues decreased by $4.1
million to $54.3 million during the first nine months of 1999 compared with 1998
as a 12% decrease in the average realized gold price to $274 per ounce was
offset partially by a 6% increase in gold sales to 198,600 ounces. During the
third quarter and first nine months of 1998, the average realized price of gold
included proceeds of $15 per ounce and $17 per ounce, respectively, from the
sale of floor program options.

     THIRD-PARTY DEBT.  At September 30, 1999, third-party debt aggregated $36.1
million, including $12.7 million from the Overseas Private Investment
Corporation ("OPIC"), for which the Company is subject to limited recourse, and
$0.2 million from other sources which the Company guarantees. Scheduled
third-party debt service for the remainder of 1999 is expected to aggregate $2.2
million, of which $1.8 million represents principal payments.

POWDERED METALS

     The Company sold for nominal value its powdered metals operations at the
end of the third quarter of 1999. The Company incurred $1.4 million of expenses
in 1999 associated with these operations, including $0.9 million from the loss
on the disposition of this business.

RUSSIAN BANKING OPERATIONS

     In the third quarter of 1998, the Company liquidated its Russian banking
operations. Accordingly, losses of $0.5 million and $6.4 million for the three
months and nine months ended September 30, 1998 were reported as discontinued
operations. In December 1998, the Company sold its stock in the bank to an
unrelated third party.

                                     OTHER

     The Company had net interest expense and other expenses of $1.2 million in
the third quarter of 1999 compared to $0.7 million in the third quarter of 1998.
For the nine months ended September 30, 1999, net interest and other expenses
were $3.8 million compared to $2.0 million in the first nine months of 1998. The
increased expenses for both periods resulted from corporate overhead no longer
allocated to discontinued operations, corporate interest no longer allocated to
the timber business as a result of the intercompany debt-to-equity conversion,
mark-to-market adjustments on the Company's interest rate protection agreements
and expenses associated with amendments to the Company's credit facility and
senior notes.

                        RECENT ACCOUNTING PRONOUNCEMENTS

     In April 1998, the American Institute of Certified Public Accountants (the
"AICPA") issued Statement of Position 98-5, "Reporting on the Costs of Start-Up
Activities." The new standard, which the Company adopted in the first quarter of
1999, required that entities expense costs of start-up activities as those costs
are incurred. The Company had capitalized certain pre-operating costs in
connection with its natural resource operations, and had capitalized certain
organizational costs associated with its financial services operations. In the
first quarter of 1999, as a result of this new standard, the Company recorded a
cumulative effect of a change in accounting principle of approximately $12.1
million related principally to its timber operations.

                   LIQUIDITY AND CAPITAL RESOURCES -- GENERAL

     The Company's liquid assets consisting of cash and marketable securities
decreased slightly by $1.2 million in the first nine months of 1999 to $46.6
million.

                                       18
<PAGE>   19

     During 1999, the Company and its commercial banking syndicate amended its
senior credit facility, which, among other things reduced the availability under
the facility from $80 million to $55 million and shortened the maturity date to
March 31, 2001. For a description of the Company's $55 million senior credit
facility and $20 million senior notes, including interest rates and applicable
covenants, see Note 5 (Notes Payable) to Notes to the Company's Consolidated
Financial Statements included elsewhere in this Quarterly Report. At September
30, 1999, the Company had borrowed $40 million under the senior credit facility
and had $20 million of senior notes outstanding.
                            ------------------------

     THE COMPANY BELIEVES THAT IT IS IN SOUND FINANCIAL CONDITION, THAT IT HAS
SUFFICIENT LIQUIDITY FROM OPERATIONS AND FINANCING FACILITIES TO COVER
SHORT-TERM COMMITMENTS AND CONTINGENCIES AND THAT IT HAS ADEQUATE CAPITAL
RESOURCES TO PROVIDE FOR LONG-TERM COMMITMENTS.

include, but are not limited to, the following as well as the factors presented
below under Year 2000 and in the Company's most recent Annual Report on Form
10-K:

     The Company derives a significant portion of its revenues from investment
management fees and underwriting and shareholder services fees. Success in the
investment management and mutual fund share distribution businesses is
substantially dependent on investment performance. Good performance stimulates
sales of shares and tends to keep redemptions low. Sales of shares result in
increased assets under management, which, in turn, generate higher management
fees. Good performance also attracts institutional accounts. Conversely,
relatively poor performance results in decreased sales and increased redemptions
and the loss of institutional accounts, with corresponding decreases in revenues
to the Company. In addition, investment performance is affected in part by
economic and market conditions which are beyond the control of the Company.
Finally, four of the Company's mutual funds (including three of the four largest
funds) have management fees which are adjusted based upon the funds' performance
relative to the performance of an established index. As a result, management fee
revenues may be subject to unexpected volatility.

     The mutual fund industry is intensely competitive and is undergoing
substantial consolidation. Many organizations in this industry are attempting to
sell and service the same clients and customers, not only with mutual fund
investments but with other financial services products. Many of the Company's
competitors have more products and product lines and substantially greater
assets under management, financial resources and name recognition.

     The Company and its domestic investment management business unit are
primarily dependent upon their contractual relationships with the Company's U.S.
mutual funds. In the event any of these agreements were canceled or not renewed
on similarly favorable terms, the Company would be substantially adversely
affected.

     Pioneer Investment Management is subject to extensive regulation in the
United States, including by the Securities and Exchange Commission and the
National Association of Securities Dealers, Inc. The Company is also subject to
the laws of non-U.S. jurisdictions and non-U.S. regulatory agencies or bodies.
The failure of the Company and its subsidiaries to comply with applicable laws
or regulations could result in fines, suspensions of personnel or other
sanctions. Changes in laws or regulations or in government policies could have a
material adverse effect on the Company.

     The Company has a significant number of operations and investments located
outside of the U.S., including the timber operations in the Russian Far East and
the financial services operations in Eastern and

                                       19

Central Europe. Foreign operations and investments may be adversely affected by
exchange controls, currency fluctuations, taxation, political and economic
instability, ineffective regulatory oversight and laws or policies of the
particular countries in which the Company may have operations. There is no
assurance that the Company can obtain permits, authorizations, regulatory
approvals and agreements to implement plans at its foreign projects under
conditions or within time frames that make such plans economically feasible.
Also, there can be no assurance that applicable laws or the governing political
authorities will not change unfavorably or that such changes will not result in
the Company having to incur material additional expenditures.

     The commercial feasibility of Forest-Starma is dependent upon a number of
factors which are not within the control of the Company including the price of
timber, weather conditions, political stability in Russia and the strength of
the Japanese and Korean economies, the primary markets for Forest-Starma's
timber. While the Company continues to believe that the project will achieve
commercial feasibility in the long term, there can be no assurance that it will
do so.

                                   YEAR 2000

     SUMMARY.  The Company has for some time been addressing actively the
potential impact of the Year 2000 problem to its businesses and has largely
completed a comprehensive project to help ensure that all of its business units
will be able to function normally before, during and after the century date
rollover. Furthermore, the Company is aware that Year 2000 issues have the
potential to impact the capital markets and macroeconomic conditions globally.
While the Company is monitoring the threat of such impact and is taking measures
reasonably designed to protect the investments of its fund shareholders and
corporate investors, there can be no assurance that factors outside its control
will not disrupt the Company's operations.

     MANAGEMENT.  The Company has been executing and managing its Year 2000
project activities at several levels within the organization, including:

     -  Regular senior-level management briefings.

     -  Regular Company Audit Committee briefings.

     -  Oversight subcommittee established by the Trustees of the Company's U.S.
        mutual funds.

     -  Year 2000 Steering Committee comprised of representatives from all
        operational areas empowered to review progress and ensure the successful
        completion of the Year 2000 project.

     -  Year 2000 project office responsible for centralized monitoring,
        reporting and support of project activities.

     -  Managers throughout the Company responsible for executing local Year
        2000 plans.

     The Company has been separately tracking the Year 2000 readiness of each of
its operating units and has created comprehensive reporting for each project
team worldwide. The Company has developed reports to monitor risk management and
project status for both systems and vendors and has utilized the services of
outside companies and consultants specializing in Year 2000 issues.

     APPROACH AND STATUS.  The Company's Year 2000 initiative has addressed
hardware, software, embedded systems and vendor systems and has consisted of the
following six phases:

     -  Awareness -- communicating management's commitment to identify and
        resolve Year 2000 issues.

     -  Inventory, Assessment, and Planning -- identifying all systems and
        vendors with potential Year 2000 problems, rating the business
        criticality of each, and planning for all project tasks.

     -  Repair -- executing all necessary system remediation plans.

     -  Testing -- ensuring that all remediated systems function correctly in
        both current date and future date environments.

                                       20

     -  Contingency Planning -- developing contingency plans and business
        continuity strategies for each business unit.

     -  Vendor Analysis -- working closely with all important third parties to
        ensure that their systems and business process have been evaluated and
        corrected adequately for any potential Year 2000 issues.

     The Company has completed the awareness, assessment and repair phases of
the project with respect to all of its core systems. Additionally, the Company
has performed stand-alone testing on all of its core information technology
applications. During the second quarter of 1999, the Company conducted an
integrated test of all systems critical to the domestic mutual fund business.
This test successfully validated that the data flow among the Company's systems
would function properly in a future-dated scenario. The Company also
participated in industry-wide testing sponsored by the Securities Industry
Association. In this testing, performed in conjunction with the National
Securities Clearing Corporation and other key third parties, the Company
successfully processed mutual fund transactions in a future-dated environment.
The contingency planning phase has been ongoing throughout the year. The Company
has assessed the Year 2000 readiness of all critical third parties but will
continue to monitor the status of these external parties through the end of the
project.

     CERTAIN RISKS AND CONTINGENCY PLANNING.  The Company segregates Year 2000
risks into four areas: (i) systems, (ii) vendors, (iii) capital markets
infrastructure and (iv) basic infrastructure.

     Systems.  Although the majority of the Company's most critical "core"
applications are provided by third parties, most of these applications are
relatively new and all have been certified as Year 2000 compliant. As a result
of successful testing, the Company believes that all core systems will operate
properly after January 1, 2000.

     Vendors.  The Company has been monitoring closely the Year 2000 progress of
all critical third parties and to date has not identified a need to replace any
of these providers.

     Capital markets infrastructure.  Particularly in the U.S., the Company is
heavily reliant upon functional capital markets (trading, clearing and
settlement). The successful industry-wide tests mitigated the Company's concerns
regarding the Year 2000 readiness of the domestic trading and settlement
infrastructure.

     Basic infrastructure.  The Company expects to be able to react
appropriately to short term or isolated disruptions of basic infrastructure
services (such as telecommunications, electricity, water and transportation)
based on its contingency plans. In the event of long term or pervasive failures,
however, the Company's risk is as significant as that of any other firm or
entity that relies upon such services.

     Internationally, the outlook is less certain with respect to the Year 2000
readiness of third parties and infrastructure elements. The Company has
indigenous operations in a number of foreign countries, and these countries have
demonstrated various levels of awareness and readiness with respect to Year 2000
issues. The Company has been preparing its systems and evaluating its vendors in
each of its core international operations in the same manner as in the U.S.
Nevertheless, the Company is subject to risks imposed by infrastructure failures
beyond its control in the countries in which it has operations.

     As part of its normal business procedures, the Company has disaster
recovery plans in place to address potential infrastructure failures, including
basic services such as electrical power and telecommunications. The Company is
leveraging and enhancing those plans to address potential Year 2000 scenarios.
With respect to Year 2000 issues, the Company's approach to contingency planning
has two additional components: (i) ensuring the Company's ability to achieve
Year 2000 compliance, even in the event of a vendor failure in 1999, and (ii)
preparing business continuity plans for various potential failure scenarios
that, despite the Company's best efforts, could occur on or around January 1,
2000.

     Since mid-1998, the Company has had Year 2000 contingency plans in place to
address century transition issues with respect to all of its primary systems and
operations. To date, substantially all of the Company's operating units have
developed contingency plans. The Company and its subsidiaries continue to review
these plans to ensure their adequacy as internal systems and/or business
conditions evolve. Contingency planning is an inherently complex and dynamic
process that must adapt to changes affecting the Company's operations.

Commencing October 1, 1999 and continuing through February 1, 2000, there will
be a freeze in effect on the introduction of new computer code or other systems
modifications. Any proposed changes during this timeframe will be approved by
the Year 2000 Steering Committee prior to being implemented. In general, it is
expected that only system changes required to address critical issues or legal
or regulatory requirements will be implemented during the freeze period. Because
we expect no significant system changes during this period, the Company does not
foresee a need to alter any of its contingency plans to accommodate system
changes. Nonetheless, the Company will continue to monitor business conditions
and infrastructure elements affecting its primary systems and operations to
ensure that no changes on these levels necessitate revisions to the existing
contingency plans. If the Company identifies any significant changes, it will
refine its contingency plans appropriately.

     COSTS.  Total Year 2000 project costs are based on currently available
information and management's estimates with respect to the costs of repairing
and replacing software, hardware, embedded systems and vendor systems and are
subject to change. For this purpose, the Company defines costs as incremental
expenditures, and cost estimates include both period costs and disbursements
that typically would be treated as capital. Estimates do not include overhead
with respect to the portion of certain employees' time allocated to the Year
2000 project or opportunity costs associated with other projects that may have
been delayed by the Year 2000 project.

     As of September 30, 1999, the Company had incurred and expensed
approximately $2.3 million in connection with its Year 2000 project. The Company
estimates its total remaining costs to be approximately $200,000, which will be
expensed as incurred during the fourth quarter of 1999. All Year 2000 project
costs have been and, the Company believes, will continue to be funded from
operating cash flows.

     Year 2000 project costs are relatively minimal primarily because the
Company owns little internally developed code. The result of the Company's
strategy of outsourcing technology-based operations is that it has only a small
base of proprietary code that it must analyze and remediate. Consequently, the
cost of the Year 2000 compliance efforts are not expected to be material to the
Company's financial position. The Company also believes that it will not incur
significant Year 2000 related costs on behalf of third parties from which it
purchases technology or outsourced technology-based functions.

     GENERAL.  The Company's ability to complete its Year 2000 project by the
dates projected and the total costs incurred to accomplish those efforts are
based on estimates of the Company's management in reliance on certain
assumptions. Such assumptions include, among others, the Company's ability to
locate and identify all potential Year 2000 issues in the systems it uses,
successful remediation efforts by the Company's vendors and other third parties
upon which it relies, the continued availability of personnel capable of
carrying out the Year 2000 project efforts and the availability of suitable
alternative software and systems. There can be no assurances that management's
reliance on such assumptions will prove to be valid. The failure of any of these
assumptions to hold true or the existence of additional significant
uncertainties could result in the inaccurateness of any of the foregoing
estimates. As a result, actual completion of the Company's Year 2000 project
could be later than anticipated or involve costs materially higher than those
estimated. Finally, investors in the Company's funds who are concerned about the
Year 2000 problem could withdraw their investments, which in turn would reduce
assets under management and related management fee revenues. The Company's
financial condition could be adversely affected if it experienced any of the
problems associated with the risks described above.

     The impact of any such failures on the Company's customers or other third
parties could vary significantly, as could such customers' or third parties'
definitions of Year 2000 compliance. Therefore, the extent of any claims
resulting from such failures is difficult to estimate. There can be no assurance
that the costs of resolving any such claims will not materially affect the
Company's business, financial condition or results of operations.
