1.    Basis of Presentation

      The consolidated financial statements of Affiliated Managers Group, Inc.
(the "Company" or "AMG") have been prepared in accordance with generally
accepted accounting principles for interim financial information and with the
instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do
not include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. The year end condensed
balance sheet data was derived from audited financial statements, but does not
include all of the disclosures required by generally accepted accounting
principles. In the opinion of management, all adjustments (consisting of normal
recurring accruals) considered necessary for a fair presentation have been
included. Certain prior year amounts have been reclassified to conform with the
current year's presentation. Operating results for interim periods are not
necessarily indicative of the results that may be expected for the full year.
The Company's Annual Report on Form 10-K for the fiscal year ended December 31,
1997 includes additional information about AMG, its operations, and its
financial position, and should be read in conjunction with this quarterly report
on Form 10-Q.

2.    Income Taxes

      A summary of the provision for income taxes is as follows (in thousands):

</TABLE>

      The Company has determined that because it is more likely than not that 
a majority of its tax net operating loss carryforwards will be utilized 
during 1998, the deferred tax valuation allowance which existed at December 
31, 1997 was no longer necessary. Accordingly, the Company expects that the 
benefit of the reversal of the allowance will be realized ratably over the 
year.

3.    Earnings Per Share

      The calculation for the basic earnings per share is based on the weighted
average of common shares outstanding during the period. The calculation for the
diluted earnings per share is based on the weighted average of common and common
equivalent shares outstanding during the period. The following is a
reconciliation of the numerators and denominators of the basic and diluted EPS
computations.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations

Forward-Looking Statements

      This report contains certain forward-looking statements within the 
meaning of the Private Securities Litigation Reform Act of 1995, which are 
based on management's current views and assumptions regarding future events 
and financial performance. Words or phrases such as "will likely result," 
"are expected to," "will continue," "is anticipated," "believes," 
"estimates," "projects" and other similar expressions are intended to 
identify such forward-looking statements. Such statements are subject to 
certain risks and uncertainties, including those discussed herein and in the 
"Business - Cautionary Statements" section of the Company's Annual Report on 
Form 10-K for the fiscal year ended December 31, 1997, that could cause 
actual results to differ materially from those discussed in the 
forward-looking statements. The Company wishes to caution readers not to 
place undue reliance on any such forward-looking statements, which speak only 
as of the date made, and the Company will not undertake to release publicly 
the result of any revisions which may be made to any forward-looking 
statements to reflect the occurrence of events or changes in circumstances 
after the date of such statements. In addition, the discussion and analysis 
below with respect to the Year 2000 Issue including i) our expectations of 
when Year 2000 compliance will actually be achieved, ii) estimates of the 
costs involved in achieving Year 2000 readiness and iii) our belief that the 
costs will not be material to operating results, are based on management's
estimates which, in turn, are based upon a number of assumptions regarding 
future events, including third party modification plans and the availability 
of certain resources. There can be no guarantee that these estimates will be 
achieved, and actual results may differ materially from management's 
estimates. Specific factors which might cause such material differences with 
respect to the Year 2000 Issue include, but are not limited to, the failure 
of third party providers to achieve represented or stated levels of Year 2000 
compliance, the availability and cost of personnel trained in this area, the 
ability to locate and correct all relevant computer codes, and similar 
uncertainties.

Overview

      The Company acquires equity positions in mid-sized investment 
management firms, and derives its revenues from such firms. AMG has a revenue 
sharing arrangement with each investment management firm in which it has an 
investment (each, an "Affiliate") which is contained in the organizational 
document of that Affiliate. Each such arrangement allocates a specified 
percentage of revenues (typically 50-70%) for use by management of that 
Affiliate in paying operating expenses of the Affiliate, including salaries 
and bonuses (the "Operating Allocation"). The remaining portion of revenues 
of the Affiliate, typically 30-50% (the "Owners' Allocation"), is allocated 
to the owners of that Affiliate (including AMG), generally in proportion to 
their ownership of the Affiliate. Since its founding in December 1993, the 
Company has completed 11 investments in Affiliates and has announced the 
signing of definitive agreements for investments in two additional 
Affiliates, Davis Hamilton Jackson & Associates, L.P. and Rorer Asset 
Management, LLC. 

      The Affiliates' revenues are derived from the provision of investment
management services for fees. Investment management fees are usually determined
as a percentage fee charged on periodic values of a client's assets under
management. In addition, several of the Affiliates charge performance-based fees
to certain of their clients; these performance-based fees result in payments to
the applicable Affiliate if specified levels of investment performance are
achieved. All references in this report to "assets under management" include
assets directly managed as well as assets underlying overlay strategies which
employ futures, options or other derivative securities to achieve a particular
investment objective.

      Assets under management were $50.1 billion at September 30, 1998 versus
$54.9 billion at June 30, 1998 and $45.7 billion at December 31, 1997. The
decline in assets in the third quarter resulted from adverse conditions in the
equity markets during the quarter, partially offset by positive net client cash
flows of $445 million for the 


                                       6
<PAGE>

quarter. Year to date growth was driven by the addition of an Affiliate and
positive net client cash flows of $1.6 billion, offsetting negative investment
performance due primarily to the adverse conditions in the equity markets during
the third quarter.

      Each of the Company's investments is accounted for under the purchase
method of accounting, under which goodwill is recorded for the excess of the
purchase price for the acquisition of interests in Affiliates over the fair
value of the net assets acquired, including acquired client relationships. As a
result of the series of investments made by the Company, intangible assets
(collectively, acquired client relationships and goodwill are referred to as
"intangible assets") constitute a substantial percentage of the assets of the
Company. At September 30, 1998, the Company's total assets were $557.8 million,
of which $163.2 million consisted of acquired client relationships and $310.4
million consisted of goodwill.

      The amortization period for intangible assets for each investment is
assessed individually, with amortization periods for the Company's investments
to date ranging from nine to 28 years in the case of acquired client
relationships and 15 to 35 years in the case of goodwill. In determining the
amortization period for intangible assets acquired, the Company considers a
number of factors including: the firm's historical and potential future
operating performance; the firm's historical and potential future rates of
attrition among clients; the stability and longevity of existing client
relationships; the firm's recent, as well as long-term, investment performance;
the characteristics of the firm's products and investment styles; the stability
and depth of the firm's management team and the firm's history and perceived
franchise or brand value. The Company performs a quarterly evaluation of
intangible assets on an Affiliate-by-Affiliate basis to determine whether there
has been any impairment in their carrying value or their useful lives. If
impairment is indicated, then the carrying amount of intangible assets,
including goodwill, will be reduced to their fair values.

      While amortization of intangible assets has been charged to the results of
operations and is expected to be a continuing material component of the
Company's operating expenses, management believes that it is important to
distinguish this expense from other operating expenses since such amortization
does not require the use of cash. Also, because the Company's distributions from
its Affiliates are based on its share of Owners' Allocation, management has
provided additional supplemental information for "cash" related earnings, as an
addition to, but not as a substitute for, measures related to net income. Such
measures are (i) EBITDA (earnings before interest expense, income taxes,
depreciation and amortization), which the Company believes is useful to
investors as an indicator of the Company's ability to service debt, make new
investments and meet working capital requirements, and (ii) EBITDA as adjusted
(earnings after interest expense and income taxes but before depreciation and
amortization), which the Company believes is useful to investors as another
indicator of funds available to the Company to make new investments, 
repurchase shares or repay debt obligations.

Three Months Ended September 30, 1998 as Compared to Three Months Ended
September 30, 1997

      The Company had net income of $5.9 million for the quarter ended September
30, 1998 compared to net income of $127,000 for the quarter ended September 30,
1997. The increase in net income resulted primarily from net income from new
investments. The Company invested in GeoCapital, LLC ("GeoCapital") in September
1997, Tweedy, Browne Company LLC ("Tweedy, Browne") in October 1997, and Essex
Investment Management Company, LLC ("Essex") in March 1998 and included their
results from their respective dates of investment.

      Revenues for the quarter ended September 30, 1998 were $55.9 million, an
increase of $35.5 million over the quarter ended September 30, 1997, primarily
as a result of the addition of the new Affiliates as described above.

      Operating expenses increased by $17.4 million to $34.5 million for the
quarter ended September 30, 1998 over the quarter ended September 30, 1997.
Compensation and related expenses increased by $9.3 million, amortization of
intangible assets increased by $3.5 million, and selling, general and
administrative expenses increased by $3.8 million. The increases in operating
expenses were primarily a result of the addition of the new Affiliates.

      Minority interest increased by $6.1 million to $8.5 million for the
quarter ended September 30, 1998 over the quarter ended September 30, 1997,
primarily as a result of the increase in revenues from the addition of the new
Affiliates.


                                       7
<PAGE>

      Interest expense increased by $2.6 million to $3.6 million for the quarter
ended September 30, 1998 over the quarter ended September 30, 1997 as a result
of the increased indebtedness incurred in connection with the investments in the
new Affiliates.

      Income tax expense was $3.9 million for the quarter ended September 30,
1998 compared to $126,000 for the quarter ended September 30, 1997. The change
in income tax expense is related to an increase in income before taxes in the
quarter ended September 30, 1998.

      EBITDA increased by $15.9 million to $18.6 million for the quarter ended
September 30, 1998 over the quarter ended September 30, 1997, primarily as a
result of the inclusion of the new Affiliates.

      EBITDA as adjusted increased by $9.5 million to $11.1 million for the
quarter ended September 30, 1998 over the quarter ended September 30, 1997 as a
result of the factors affecting net income as described above, before non-cash
expenses such as amortization of intangible assets and depreciation of $5.3
million for the quarter ended September 30, 1998.

Nine Months Ended September 30, 1998 as Compared to Nine Months Ended
September 30, 1997

      The Company had net income of $16.2 million for the nine months ended 
September 30, 1998 compared to net income of $833,000 for the nine months 
ended September 30, 1997. The increase in net income resulted primarily from 
net income from new investments. The Company invested in Gofen and Glossberg, 
L.L.C. ("Gofen and Glossberg") in May 1997, GeoCapital in September 1997, 
Tweedy, Browne in October 1997, and Essex in March 1998 (collectively, the 
"New Affiliates") and included their results from their respective dates of 
investment.

      Revenues for the nine months ended September 30, 1998 were $158.2 million,
an increase of $104.9 million over the nine months ended September 30, 1997,
primarily as a result of the addition of the New Affiliates.

      Operating expenses increased by $53.6 million to $97.9 million for the
nine months ended September 30, 1998 over the nine months ended September 30,
1997. Compensation and related expenses increased by $29.7 million, amortization
of intangible assets increased by $9.8 million, selling, general and
administrative expenses increased by $11.8 million, and other operating expenses
increased by $1.6 million. The growth in operating expenses was primarily a
result of the addition of the New Affiliates.

      Minority interest increased by $18.0 million to $24.0 million for the nine
months ended September 30, 1998 over the nine months ended September 30, 1997,
primarily as a result of the addition of New Affiliates.

      Interest expense increased by $7.9 million to $10.6 million for the 
nine months ended September 30, 1998 over the nine months ended September 30, 
1997, as a result of the increased indebtedness incurred in connection with 
the investments in the New Affiliates.

      Income tax expense was $10.8 million for the nine months ended 
September 30, 1998 compared to $221,000 for the nine months ended September 
30, 1997. The change in income tax expense is related to an increase in 
income before taxes in the nine months ended September 30, 1998 and the 
recognition of the benefit of the reversal of the Company's tax valuation 
allowance at December 31, 1996 in the nine months ended September 30, 1997.

      EBITDA increased by $44.4 million to $52.4 million for the nine months
ended September 30, 1998 over the nine months ended September 30, 1997,
primarily as a result of the inclusion of the New Affiliates.

      EBITDA as adjusted increased by $26.0 million to $31.0 million for the
nine months ended September 30, 1998 over the nine months ended September 30,
1997 as a result of the factors affecting net income as described above, before
non-cash expenses such as amortization of intangible assets and depreciation of
$14.7 million for the nine months ended September 30, 1998.

Liquidity and Capital Resources

      At September 30, 1998, the Company had cash and cash equivalents of $29.9
million and outstanding borrowings under its revolving credit facility ("Credit
Facility") of $200.3 million. The Credit Facility allows for borrowings up to
$300 million (which may be increased to $400 million upon the approval of the
lenders) and matures in December 2002. The Company pays interest at either LIBOR
plus a margin or the Prime Rate plus a margin, as well as a commitment fee on
the daily unused portion of the facility.

      On September 11, 1998, the Company's Board of Directors authorized a share
repurchase program pursuant to which AMG could repurchase up to five percent of
AMG's issued and outstanding shares of Common Stock. During the quarter ended
September 30, 1998, the Company repurchased 84,400 shares for $1.5 million.
Subsequent to September 30, 1998 the Company has repurchased an additional
62,600 shares for $1.1 million.

      On October 22, 1998, AMG announced an agreement to acquire a 65% 
interest in Davis Hamilton Jackson & Associates, L.P., which will hold the 
business presently operated by Davis Hamilton Jackson & Associates, Inc. 
("DHJA"). DHJA is a Houston based asset management firm with approximately 
$3.0 billion of assets under management at September 30, 1998. On November 9, 
1998, the Company announced an agreement to acquire an approximately 65% 
interest in Rorer Asset Management, LLC, which will hold the business 
presently operated by Edward C. Rorer & Co., Inc. ("Rorer"). Rorer is a 
Philadelphia based investment advisor with approximately $3.6 billion of 
assets under management at September 30, 1998. AMG will pay approximately $65 
million in cash for its investment in Rorer. AMG will finance these two 
investments with borrowings under its Credit Facility.

      In order to provide the funds necessary for the Company to continue to
acquire interests in investment management firms, including additional
investments in existing Affiliates, it will be necessary for the Company to
incur, from time to time, additional long-term debt and/or issue equity or debt
securities, depending on market and other conditions. There can be no assurance
that such additional financing will be available or become available on terms
acceptable to the Company.

Recent Accounting Developments

      In June 1997, the Financial Accounting Standards Board (the "FASB") issued
Statement of Financial Accounting Standards No. 131, "Disclosures about Segments
of an Enterprise and Related Information" ("FAS 131"). FAS 131 requires
disclosure of financial and descriptive information about an entity's reportable
operating segments. This standard is effective for financial statements for
periods beginning after December 15, 1997, with restatement of comparative
information for prior periods. The standard is not required to be applied to
interim financial statements in the initial year of its application.

      In June 1998, the FASB issued Statement of Financial Accounting Standards
No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("FAS
133"). FAS 133 standardizes the accounting for derivative instruments by
requiring that all derivatives be recognized as assets and liabilities and
measured at fair value. FAS 133 is effective for financial statements for fiscal
years beginning after June 15, 1999.

      The Company does not believe that the implementation of FAS 131 or FAS 133
will have a material impact on the Company's financial statements.

Impact of the Year 2000 Issue

    The Year 2000 Issue is the result of computer programs being written using
two digits rather than four to define the applicable year. Any of the Company's
or its Affiliates' computer programs that have date-sensitive software may
recognize a date using "00" as the year 1900 rather than the year 2000. This
could result in a system failure or miscalculations causing disruptions of
operations, including, among other things, a temporary inability to process
transactions, send invoices, or engage in similar normal business activities. 
Such disruptions could affect the Company's Affiliates' ability to provide 
advisory services.

    The Company has identified all of the significant computers, software 
applications and related equipment at the holding company that need to be 
modified, upgraded or replaced to minimize the possibility of a material 
disruption to its business.

                                       9
<PAGE>

    In addition, the Company has established with each Affiliate a timeline 
for compliance and has received estimates of compliance costs. As part of the 
general compliance program, each of the Affiliates has assigned 
responsibility for the Year 2000 Issue to a member of senior management to 
ensure both proprietary and third party vendor systems will be Year 2000 
compliant.

    All Affiliates have completed their assessment and plans are in place for 
the renovation or replacement of non-compliant systems. The completion of 
renovation or replacement and the subsequent testing and implementation are 
scheduled for the fourth quarter of 1998 and early 1999, while industry wide 
testing will take place in 1999. If the Affiliates fail to resolve their Year 
2000 issues, the Affiliates' and, accordingly, the Company's business would 
be materially disrupted.

    Outside service providers perform certain processes which are critical 
for the Company's Affiliates, including transfer agency and custody 
functions. The progress of these parties is being monitored by the Company's 
Affiliates. However, the Affiliates have limited or no control over the 
actions of these outside parties and in certain cases no alternative vendors 
are available. If these parties fail to resolve Year 2000 issues, the 
Affiliates and, accordingly, the Company's business would be materially 
disrupted.

    The Company and its Affiliates estimate that its compliance activities 
will be completed no later than the second quarter of 1999. Because most of 
the Year 2000 costs are being covered by the Affiliates' Operating 
Allocation, the total costs of this effort to the Company (as opposed to the 
affiliates) are estimated to be less than $800,000 for the four year period 
ending December 31, 1999.

European Monetary Unit

    On January 1, 1999, a single currency for the European Economic and 
Monetary Union (the "Euro") is scheduled to replace the national currency for 
participating member countries which include countries in which several of 
the Company's Affiliates do business. The managed funds and financial 
products of these Affiliates have investments in countries whose currencies 
will be replaced by the Euro. Many aspects of these Affiliates' investment 
process, including trading, foreign exchange, payments, settlements, cash 
accounts, custodial accounts and accounting will be affected by the 
implementation of the Euro (the "Euro Issue").

    The Affiliates impacted have created teams to determine changes that will 
be required in connection with the Euro Issue in order to process 
transactions accurately with minimal disruption to business activities. These 
Affiliates are also communicating with its external partners and vendors to 
assess their readiness to manage the Euro Issue without disruption to their 
business or operations. If these Affiliates fail to resolve their Euro Issue, 
the Affiliates and, accordingly, the Company's business would be materially 
disrupted.

            (a) Upon the terms and subject to the conditions contained in this

to the Closing Date, an aggregate amount equal to Sixty-Five Million Dollars
($65,000,000), subject to adjustment as set forth in Section 1.2(b) below, in
immediately available funds (as so adjusted, the "Purchase Price"), in full
consideration for the sale of the Company Shares to AMG; the Purchase Price
shall be paid to the Stockholders' bank accounts in the specific amounts set
forth in Schedule 1.2 hereto; provided, however, that AMG shall withhold from
such payment of the Purchase Price at the Closing any amounts paid to the Escrow
Agent pursuant to the Escrow Agreement (each as defined in Section 1.2(e)).

            (b) If, as of the Closing, the Company shall have received Consents
from clients whose Advisory Contracts provide for the payment (based on the
Contract Value of each such Advisory Contract) of fees constituting less than
one hundred percent (100%) of the Base Fees, then the payment delivered to each
Stockholder pursuant to Section 1.2(a) above, will be reduced to an amount equal
to the product of (A) the amount set forth in Schedule 1.2 hereto opposite such
Stockholder's name, multiplied by (B) a fraction (x) the numerator of which
shall be the sum of the Contract Values of each Advisory Contract of the Company
which has not been terminated at or prior to the Closing, and with respect to
which the Client of the Company has given its Consent, and (y) the denominator
of which shall be the Base Fees.

            (c) At the Closing, upon the terms and subject to the conditions
contained in this Agreement, each Stockholder shall deliver to AMG all of the
certificates representing such Stockholder's Company Shares, duly endorsed for
transfer to AMG in form and substance reasonably satisfactory to AMG, together
with such other transfer documentation as AMG has reasonably requested.

            (d) At the Closing, upon the terms and subject to the conditions
contained in each such Option Cancellation Agreement, AMG will pay to each
holder of options to purchase Common Stock who is a party to an Option
Cancellation Agreement with AMG, in full cancellation and settlement of such
options, the consideration provided for in such Option Cancellation Agreement,
and upon such payment by AMG, each such option shall be canceled by the Company
and the holder thereof shall be deemed by his or her acceptance of such
consideration to have released any and all rights such holder had or may have
had in respect of such option.

            (e) Prior to the Closing Date, the Stockholders shall enter into an
escrow agreement (the "Escrow Agreement") in form and substance reasonably
acceptable to AMG with a qualified escrow agent (the "Escrow Agent") reasonably
acceptable to AMG providing for a portion of the Purchase Price to be paid by
AMG into escrow at the Closing for the benefit of the Stockholders in amounts
and proportions consistent with such Stockholders' respective anticipated
liabilities pursuant to Section 6.1(i)(A) hereof (such liabilities to be
estimated for such purpose by the Company in good faith in a written schedule
delivered by the Company to the Stockholders and to AMG at least twenty (20)
days prior to the Closing Date, and in any event at least ten (10) days prior to
entering into the Escrow Agreement), and such escrowed monies shall be applied
by the Escrow Agent in satisfaction of the tax liabilities of the Company under
Section 1374 of the Code and any excess escrowed monies and any interest earned
on the escrowed monies shall be released to the Stockholders following the
filing of the Form 1120S for the Company for the period ending on the Closing
Date (provided that the Stockholders shall remain liable for any additional tax
liabilities pursuant to the terms of Article 6 hereof). At the Closing, AMG
shall pay to the Escrow


                                       2

Agent on behalf of the Stockholders that portion of the Purchase Price provided
for in the Escrow Agreement. Each Stockholder agrees to negotiate in good faith
to enter into an Escrow Agreement reasonably acceptable to AMG with an Escrow
Agent reasonably acceptable to AMG at least ten (10) days prior to the Closing
Date. Notwithstanding anything else contained in this Section 1.2(e), in the
event the Stockholders fail to enter into an Escrow Agreement in form and
substance reasonably acceptable to AMG with an Escrow Agent reasonably
acceptable to AMG at least ten (10) days prior to the Closing Date, AMG shall
not be obligated to pay any portion of the Purchase Price into escrow, and shall
instead pay the entire Purchase Price to the Stockholders at the Closing.

      1.3 Directors and Officers. On or prior to the Closing Date, the Company
shall deliver to AMG evidence satisfactory to AMG of the resignations of the
directors and officers of the Company, such resignations to be effective as of
the Closing.

      1.4 Time and Place of Closing. The closing of the Purchase and the related
transactions provided for in this Agreement (the "Closing") shall be held at the
offices of Simpson Thacher & Bartlett, 425 Lexington Avenue, New York, New York

the Company.

the Closing, at the request of AMG and without further consideration, execute
and deliver further instruments of transfer and assignment and take such other
action as AMG may reasonably require to fully implement the provisions of this
Agreement.

      1.6 Transfer Taxes. All transfer taxes, fees and duties under applicable
law incurred in connection with the Purchase will be borne and paid by the
Stockholders, and the Stockholders shall promptly reimburse the Company and AMG
for any such tax, fee or duty which any of them is required to pay under
applicable law.

hereunder.

      3.2 Organization and Qualification of the Company and the LLC.

            (a) The Company is a corporation duly organized, validly existing
and in good standing under the laws of the Commonwealth of Pennsylvania, with
full power and authority to own or lease its properties and to conduct its
business in the manner and in the places where such properties are owned or
leased or such business is currently conducted. The copies of the Company's
Articles of Incorporation, as amended to date (the "Articles of Incorporation"),
certified by the Department of State of the Commonwealth of Pennsylvania, and of
the Company's by-laws, as amended to date, certified by the Company's Secretary,
and heretofore delivered to AMG, are complete and correct, and no amendments
thereto are pending. The Company is not in violation of any term of its Articles
of Incorporation or by-laws. The Company is duly qualified to do business as a
foreign corporation under the laws of each jurisdiction in which the nature of
its business or the ownership or leasing of its properties requires such
qualification, except where the failure to be so licensed or qualified could not
have a Material Adverse Effect (as such term is defined in Section 14.1 hereof)
on the Company, the LLC or AMG.

            (b) The LLC is a limited liability company duly formed, validly
existing and in good standing under the laws of the State of Delaware with full
power and authority under the Delaware Limited Liability Company Act, 6 Del. C.
ss.18-101, et seq., as amended from time to time (the "Delaware Act") and the
Existing LLC Agreement (and, after the effectiveness of the Restated LLC
Agreement, the Restated LLC Agreement) to own or lease its properties and to
conduct its business in the manner and in the places where such properties are
owned or leased or such business is currently conducted or proposed to be
conducted (and, after giving effect to the Closing and the Asset Transfer, the
business currently conducted by the Company). The copies of the LLC's Existing
LLC Agreement (as such term is defined in Section 14.1 hereof), certified by the
Company in its capacity as Manager Member of the LLC, and of the LLC's
Certificate of Formation, as


                                       4
<PAGE>

amended to date (the "Existing Certificate of Formation"), certified by the
Secretary of State of the State of Delaware, each as heretofore delivered to
AMG, are complete and correct, and no amendments thereto are pending. The LLC is
not in violation of any term of the Existing LLC Agreement. The LLC is duly
qualified to do business as a foreign limited liability company under the laws
of each jurisdiction in which the nature of its business or the ownership or
leasing of its properties requires such qualification (and, after giving effect
to the Closing and the Asset Transfer, the business currently conducted by the
Company). As of the Closing, the LLC shall be duly qualified to do business as a
foreign limited liability company under the laws of each jurisdiction in which
the nature of the business it will conduct after giving effect to the Asset
Transfer, or the ownership or leasing of the properties it will receive in the
Asset Transfer, requires such qualification.

      3.3 Capital Stock of the Company; Beneficial Ownership.

            (a) The authorized capital stock of the Company consists exclusively
of (i) five million (5,000,000) shares of Common Stock, no par value per share,
of which one million (1,000,000) shares are outstanding, and all of such
outstanding shares are duly and validly authorized, issued, outstanding, fully
paid and non-assessable, and (ii) twenty thousand (20,000) shares of preferred
stock, par value $100.00 per share, of which no shares are issued or
outstanding.. Except as set forth in Schedule 3.3 hereto, there are no
outstanding options, warrants, rights, commitments, preemptive rights or
agreements of any kind for the issuance or sale of, or outstanding securities
convertible into, any additional shares of capital stock of any class of the
Company. None of the Company's capital stock has been issued in violation of any
Laws or Regulations. Except as set forth in Schedule 3.3 hereto, there are no
voting trusts, voting agreements, proxies or other agreements, instruments or
undertakings with respect to the voting of the Company Shares to which the
Company or any of the Stockholders is a party. No Stockholder has any right of
appraisal with respect to the Company's capital stock by reason of the
transactions contemplated by this Agreement. The Company does not have any
outstanding debt securities.

            (b) Each Stockholder owns of record and, to the knowledge of the
Company and the Majority Stockholders, beneficially the Company Shares set forth
opposite such Stockholder's name on Schedule 1.2 hereto, free and clear of any
Claims, except as reflected in Schedule 3.3 hereto. Each Stockholder is, to the
knowledge of the Company and the Majority Stockholders, the beneficial and
record holder of the Company Shares set forth opposite his name on Schedule 1.2
hereof, and the capital stock shown on Schedule 1.2 opposite his name are the
only shares of capital stock of the Company held by such Stockholder or with
respect to which such Stockholder has any rights.

      3.4 Subsidiaries.

            (a) Other than the Company's interest in the LLC, and except as
otherwise set forth on Schedule 3.4(a) hereto, the Company has no, nor has it
ever had any, subsidiaries, debt or equity investments or other ownership
interests, direct or indirect, in any other Person, except for cash and
cash-equivalents. The LLC has no subsidiaries or investments in any other
Person.

            (b) The Company is the sole member of the LLC, and the
capitalization of the LLC (with respect to capital accounts and interests in
profits) is as set forth in Schedule 3.4(b)(i) hereto, with all such interests
owned beneficially and of record by the Company, free and clear of any Claims
other than the restrictions imposed pursuant to this Agreement. After giving
effect to the Closing and the effectiveness of the Restated LLC Agreement, the
capitalization of the LLC will be as set forth in Schedule 3.4(b)(ii) hereto,
with all such interests owned of record and, to the knowledge of the Company and
the Majority Stockholders, beneficially by the entities and in the amounts
indicated in Schedule 3.4(b)(ii), in each case, other than as to the interests
of the Manager Member, free and clear of any Claims other than restrictions
imposed pursuant to the Restated LLC Agreement. All outstanding interests in the
LLC have been duly authorized and issued under the Existing LLC Agreement and,
after giving effect to the effectiveness of the Restated LLC Agreement, the
Restated LLC Agreement. After giving effect to the Closing and the restatement
of the Existing LLC Agreement into the Restated LLC Agreement, the Company will
be the sole Manager Member (as such term is defined in the Restated LLC
Agreement) and manager (as such term is defined in the Delaware Act) of the LLC,
and, exclusive of any impairment of title or claims created by AMG, the Company
will have good and marketable title to its interest in the LLC, as shown in
Schedule 3.4(b)(ii), free and clear of any Claims other than the restrictions
imposed pursuant to this Agreement and the Restated LLC Agreement and claims
created by AMG. Except as set forth in this Agreement or in the Restated LLC
Agreement, there are no rights, commitments, agreements or understandings
obligating or which might obligate the LLC or any of its members (including,
without limitation, the Company (other than any such items created by AMG)) to
issue, transfer, sell or redeem any securities or interests in the LLC. Except
as set forth in Schedule 3.3 hereto or in the Restated LLC Agreement, there are
no voting trusts, voting agreements, proxies or other agreements, instruments or
undertakings with respect to the voting of any interests in the LLC to which the
Company, the LLC or any of the Stockholders is a party.

            (b) The LLC has all requisite power and authority under the Existing
LLC Agreement and the Delaware Act (and, after the effectiveness of the Restated
LLC Agreement, under the Restated LLC Agreement and the Delaware Act) to enter
into each agreement, document and instrument executed and delivered, or to be

Agreement and to carry out the transactions contemplated hereby and thereby. The

      3.6 Real and Personal Property.

            (a) (i) Neither the Company nor the LLC own any real property. All
of the real property leased by the Company or the LLC is identified in Schedule
3.6(a) hereto (herein referred to as the "Real Property.")

                  (ii) All leases of Real Property by the Company or the LLC are
      identified in Schedule 3.6(a), and true and complete copies thereof have
      been delivered to AMG. Each of said leases has been duly authorized and
      executed by the parties thereto and is in full force and effect. Neither
      the Company nor the LLC is in material default under any of said leases,
      nor has any event occurred which, with the giving of notice or the passage
      of time, or both, would give rise to such a material default. To the
      Company's and each Majority Stockholder's knowledge, each other party to
      each of said leases is not in material default under any of said leases
      and there is no event which, with the giving of notice or the passage of
      time, or both, would give rise to such a material default. Subject to
      receipt of the requisite consent(s) to assignment (as identified on
      Schedule 3.5), after giving effect to the Closing and the Asset Transfer,
      each lease identified in Schedule 3.6(a) will be valid and effective in
      accordance with its terms, with the LLC having succeeded to all the rights
      and obligations of the Company thereunder.

            (b) Attached hereto as Schedule 3.6(b) is a list of all the
categories of material assets of the Company including Intellectual Property (as
such term is defined in Section 3.14 hereof). Except as set forth in Schedule
3.6(b) hereto, as of the date hereof, the Company owns all its assets free and
clear of any Claims. All the assets listed in Schedules to the Asset Transfer
Agreement included in Exhibit 2.1 hereto are being transferred to the LLC and,
after giving effect to such transfers, the LLC will own all such assets free and
clear of any Claims. The assets listed in Schedule 3.6(b) hereto include all the
material assets used in, and all the assets necessary for, the conduct of the
business of the Company as currently conducted and all the material assets which
the LLC can reasonably be expected to require for the conduct of such business
immediately following the Closing and the Asset Transfer, and are suitable and
in an appropriate condition for such purpose.

      3.7 Assets Under Management. (a) The aggregate assets under management by
the Company as of June 30, 1998 and September 30, 1998 are accurately set forth

      determining whether the closing condition set forth in Section 9.2(a) is
      satisfied or for purposes of determining liability for any breach of this
      representation and warranty following the Closing).

Except as set forth in Schedule 3.7 and expressly described thereon, there are
no contracts, agreements, arrangements or understandings pursuant to which the
Company has undertaken or agreed to cap, waive, offset, reimburse or otherwise
reduce any or all fees or charges payable by any of the clients set forth in
Schedule 3.7 or pursuant to any of the contracts set forth in Schedule 3.7.
Except as is set forth in Schedule 3.7 hereto, no client of the Company has
expressed in writing to the Company an intention to terminate or reduce its
investment relationship with the Company, or adjust the fee schedule with
respect to any contract in a manner which would reduce the fee to the Company
(or, after giving effect to the Asset Transfer, the fee to the LLC).

            (b) As of the date of this Agreement, the Company does not have any
clients with respect to which fees payable to the Company are based on
performance or otherwise provide for compensation on the basis of a share of
capital gains upon or capital appreciation of the funds (or any portion thereof)
of any client.

            (c) Each account to which the Company provides Investment Management
Services that is (i) an employee benefit plan, as defined in Section 3(3) of
ERISA that is subject to Title I of ERISA; (ii) a person acting on behalf of
such a plan; or (iii) an entity whose assets include the assets of such a plan,
within the meaning of ERISA and applicable regulations (hereinafter referred to
as an "ERISA Client") have been managed by the Company such that the Company in
the exercise of such management is in compliance in all material respects with
the applicable requirements of ERISA. Schedule 3.7 identifies each Client that
is an ERISA Client with an appropriate footnote. The Company is a qualified
professional asset manager (as such term is used in Prohibited Transaction Class
Exemption 84-14) ("QPAM"), and as of the commencement of business on the first
business day following the Closing Date, the LLC will be a QPAM.

            (d) To the knowledge of the Company and the Majority Stockholders,
no controversy or disagreement exists between the Company and any client of the
Company that has had or could reasonably be expected to have a Material Adverse
Effect on the Company, the LLC or AMG.

            (e) Except as set forth in Schedule 3.7(e), no exemptive orders,
"no-action" letters or similar exemptions or regulatory relief have been
obtained, nor are any requests pending therefor, with respect to the Company,
the LLC, any Stockholder, officer, director or employee of the Company in
connection with the business of the Company or the LLC, or any client of the
Company in connection with the provision of Investment Management Services to
such client by the Company or the LLC.

      3.8 Financial Statements.

            (a) The Company has delivered to AMG true and complete copies of the
following financial statements, copies of which are attached hereto as Schedule
3.8(a):

                  (i) Audited balance sheets of the Company at December 31,
      1995, December 31, 1996 and December 31, 1997, and audited statements of
      income, retained earnings and cash flows for each of the three (3) years
      then ended. The audited balance sheet of the Company at December 31, 1997
      (including the notes thereto) is referred to hereinafter as the "Base
      Balance Sheet."

                  (ii) An unaudited balance sheet of the Company at June 30,
      1998 and at September 30, 1998, and statements of income and retained
      earnings for the periods then ended, certified by the Company's President.

      Said financial statements have been prepared in accordance with GAAP using
the accrual method of accounting, applied consistently during the periods
covered thereby (except that the Company's unaudited financial statements do not
include footnote disclosure and are subject to normal year-end audit adjustments
which are not in the aggregate material) present fairly the financial condition
of the Company at the dates of said statements and the results of its operations
for the periods covered thereby.

            (b) As of the date of the Base Balance Sheet, the Company did not
have any material liabilities of any nature, whether accrued, absolute,
contingent or otherwise, asserted or unasserted, known or unknown (including,
without limitation, liabilities as guarantor or otherwise with respect to
obligations of others, liabilities for taxes due or then accrued or to become
due, or contingent or potential liabilities relating to activities of the
Company or the conduct of its businesses prior to the date of the Base Balance
Sheet regardless of whether claims in respect thereof had been asserted as of
such date), except liabilities stated or adequately reserved against on the Base
Balance Sheet, or reflected in Schedule 3.8(b) as of the date of this Agreement.

            (c) Neither the Company nor the LLC has (including, with respect to
the giving of this representation pursuant to Section 9.2 hereof, after giving
effect to the Asset Transfer) any material liabilities of any nature, whether
accrued, absolute, contingent or otherwise, asserted or unasserted, known or
unknown (including, without limitation, liabilities as guarantor or otherwise
with respect to obligations of others, or liabilities for taxes due or then
accrued or to become due or contingent or potential liabilities relating to
activities of the Company or the LLC or the conduct of their businesses prior to
the date hereof or the Closing, as the case may be, regardless of whether claims
in respect thereof had been asserted as of such date), except: (i) liabilities
reflected or adequately reserved against on the Base Balance Sheet, (ii)
liabilities reflected in Schedule 3.8(c) as of the date of this Agreement or on
the unaudited balance sheet of the Company at September 30, 1998, included as
part of Schedule 3.8(a)), or (iii) liabilities incurred after the date of the
unaudited balance sheet of the Company at June 30, 1998 in the ordinary course
of business of the Company or the LLC consistent with past practice which could
not, individually or in the aggregate, have a Material Adverse Effect on the
Company, the LLC or AMG and which, in the case of liabilities incurred after the
date of this Agreement, also are consistent with the terms of this Agreement.

      3.9 Taxes.

            (a) The Company and the LLC have each paid or caused to be paid all
federal, state, local, foreign, and other taxes, government fees or the like,
including, without limitation, income taxes, estimated taxes, alternative
minimum taxes, franchise taxes, capital stock taxes, sales taxes, use taxes, ad
valorem or value added taxes, employment and payroll-related taxes, withholding
taxes, and transfer taxes, whether or not measured in whole or in part by net
income, and all deficiencies, or other additions to tax, interest, fines and
penalties owed by it (collectively, "Taxes" and, each individually, a "Tax"),
required to be paid by it through the date hereof, whether disputed or not. The
unpaid taxes of the Company and the LLC (i) did not, as of September 30, 1998,
exceed the reserve for tax liability (rather than the reserve for deferred Taxes
established to reflect timing differences between book and tax income) set forth
in the unaudited balance sheet of the Company at September 30, 1998 (a copy of
which is attached hereto as part of Schedule 3.8(a)) (rather than in any notes
thereto) and (ii) do not exceed that reserve as adjusted for the passage of time
through the date hereof and the date of the Closing in accordance with the past
custom and practice of the Company in filing its Tax Returns. All Taxes required
to be withheld by the Company including, but not limited to, Taxes arising as a
result of payments to foreign persons or to employees of the Company, have been
collected and withheld, and have either been paid to the respective governmental
agencies, set aside in accounts for such purpose, or accrued, reserved against,
and entered on the books and records of the Company.

            (b) Each of the Company and the LLC has, in accordance with
applicable law, filed all Tax Returns required to be filed by it, and all such
returns correctly and accurately in all material respects set forth the amount
of any Taxes relating to the applicable period. A list of all Tax Returns filed
with respect to the Company for taxable periods ended on or after December 31,
1992, is set forth in Schedule 3.9(b) attached hereto, and said Schedule
indicates those returns that have been audited or currently are the subject of
an audit. For each taxable period of the Company ended on or after December 31,
1992, the Company has delivered to AMG correct and complete copies of all Tax
Returns, examination reports and statements of deficiencies assessed against or
agreed to by the Company.

            (c) Neither the IRS nor any other governmental authority responsible
for the imposition or collection of any Tax (a "Taxing Authority") is now
asserting or, to the knowledge of the Company or any Majority Stockholder,
threatening to assert against the Company or the LLC any deficiency or claim for
additional Taxes. No claim has ever been made by a Taxing Authority in a
jurisdiction where the Company or the LLC does not file reports and returns that
the Company or the LLC is or may be subject to taxation by that jurisdiction.
There are no security interests on any of the assets of the Company or the LLC
that arose in connection with any failure (or alleged failure) to pay any Taxes.
Neither the Company nor the LLC has ever entered into a closing agreement
pursuant to Section 7121 of the Internal Revenue Code of 1986, as amended (the
"Code").

            (d) There has not been any audit of any Tax Return filed by the
Company, no such audit is in progress, and the Company has not been notified by
any Taxing Authority that any such audit is contemplated or pending. No
extension of time with respect to any date on which a Tax Return was or is to be
filed by the Company or the LLC is in force, and no waiver or agreement by


                                       12
<PAGE>

the Company or the LLC is in force for the extension of time for the assessment
or payment of any Taxes.

            (e) Neither the Company nor the LLC has ever been (or has ever had
any liability for unpaid Taxes because it once was) a member of an "affiliated
group" (as defined in Section 1504(a) of the Code). Neither the Company nor the
LLC has ever filed, or has ever been required to file, a consolidated, combined
or unitary tax return with any other entity. Neither the Company nor the LLC is
a party to, nor has any obligation under, any tax sharing agreement. Neither the
Company nor the LLC has any liability for the Taxes of any Person as a
transferee or successor, by contract or otherwise.

            (f) The Company (and any predecessor of the Company) has been a
validly electing S corporation within the meaning of Sections 1361 and 1362 of
the Code and a validly electing S corporation within the meaning of the
applicable state law statutes in the states listed in Schedule 3.9(f) attached
hereto at all times since January 1, 1997, and the Company will be an S
corporation up to the Closing.

            (g) None of the Company's or the LLC's payroll, property, or
receipts, or other factors used in a particular state's apportionment or
allocation formula results in an apportionment or allocation of business income
to any state or other jurisdiction other than the Commonwealth of Pennsylvania,
and neither the Company nor the LLC has any non-business income that is
allocated, apportioned or otherwise sourced to any state, commonwealth or other
jurisdiction than the State of Pennsylvania.

            (h) Except as set forth in Schedule 3.9(h) attached hereto, the
Company will not be liable for any Tax under Section 1374 of the Code in
connection with the deemed sale of the Company's assets caused by the Elections.
The Company has not, in the past ten (10) years, (i) acquired assets from
another corporation in a transaction in which the Company's Tax basis for the
acquired assets was determined, in whole or in part, by reference to the Tax
basis of the acquired assets (or any other property) in the hands of the
transferor, or (ii) acquired the stock of any corporation which became a
qualified subchapter S subsidiary.

            (i) For purposes of this Agreement, all references to Sections of
the Code shall include any predecessor provisions to such Sections and any
similar provisions of federal, state, local or foreign law.

      3.10 Collectibility of Accounts Receivable. All of the accounts receivable
of the Company shown or reflected on the Company's balance sheet as of September
30, 1998, or existing at the date hereof (less the reserve for bad debts set
forth on such balance sheet) were or are valid and enforceable claims, fully
collectible and subject to no setoff or counterclaim. Neither the Company nor
the LLC has any accounts or loans receivable from any person, firm or
corporation or other entity which is affiliated with the Company or from any
director, officer or employee of the Company except as disclosed in Schedule
3.10 hereto.

      3.11 Absence of Certain Changes. Except as disclosed in Schedule 3.11
attached hereto, since the date of the Base Balance Sheet neither the Company
nor the LLC has (i) suffered any


                                       13
<PAGE>

condition, event or occurrence which has had or could reasonably be expected to
have a Material Adverse Effect on the Company, the LLC or AMG or (ii) taken any
action which, had it occurred after the date hereof and prior to the Closing,
would have required AMG's consent under Section 5.5 hereof.

      3.12 Ordinary Course. Except as otherwise specifically contemplated by
this Agreement, since the date of the Base Balance Sheet, the Company has
conducted its business only in the ordinary course and consistently with its
prior practices. Since its formation, the LLC has only conducted those
operations necessary for the performance of its obligations hereunder and
activities necessary in connection herewith and therewith, and the LLC does not
have any assets or liabilities (other than pursuant to the Existing LLC
Agreement and other than liabilities incidental to the formation of the LLC
which are not in the aggregate material).

      3.13 Banking Relations. All of the arrangements which the Company or the
LLC has with any banking institution are, in all material respects, completely
and accurately described in Schedule 3.13 attached hereto, indicating with
respect to each of such arrangements the type of arrangement maintained (such as
checking account, borrowing arrangements, etc.) and the person or persons
authorized as signatories or otherwise to take action in respect thereof.

      3.14  Intellectual Property.

            (a) Except as described in Schedule 3.14, the Company and, after
giving effect to the Closing and the Asset Transfer, the LLC, has exclusive
ownership of, or exclusive license to use, all patent, copyright, trade secret,
trademark, trade name, service mark, formulas, designs, inventions or other
similar proprietary rights (including, without limitation, all rights in and to
the name "Rorer Asset Management") (collectively, "Intellectual Property") used
in the business of the Company as presently conducted. All of the rights of the
Company in such Intellectual Property are freely transferable. There are no
claims or demands of any other person or entity pertaining to any of such
Intellectual Property owned by the Company and no proceedings have been
instituted, or are pending or, to the knowledge of the Company and the Majority
Stockholders, threatened, which challenge the rights of the Company or the LLC
in respect of the Intellectual Property. The Company and, after giving effect to
the Closing and the Asset Transfer, the LLC, has the right to use, free and
clear of any claims or rights of other persons except, with respect to licensed
assets, the rights of the owner/licensor thereof, all customer lists (subject to
applicable confidentiality restrictions), investment or other processes,
computer software (other than rights of other Persons in computer software that
is generally available to the public in the retail marketplace), systems, data
compilations, research results and other information required for or incident to
its services or its business as presently conducted.

            (b) All items of Intellectual Property which are material to the
business or operations of the Company and, after giving effect to the Closing
and the Asset Transfer, the LLC, are listed in Schedule 3.14. The Company has no
patents, patent applications, trademark registrations, trademark applications or
registered copyrights.

            (c) All licenses or other agreements under which the Company is
granted rights in items of Intellectual Property which are material to the
business or operations of the Company


                                       14
<PAGE>

and, after giving effect to the Closing and the Asset Transfer, the LLC, are
listed in Schedule 3.14. All said licenses or other agreements are in full force
and effect, there is no material default by any party thereto, and, except as
set forth in Schedule 3.14, all of the rights of the Company thereunder are
freely assignable. To the knowledge of the Company and the Majority
Stockholders, the licensors under said licenses and other agreements have and
had all requisite power and authority to grant the rights purported to be
conferred thereby. True and complete copies of all such licenses or other
agreements, and any amendments thereto, have been provided to AMG.

            (d) The Company has not granted rights to others in Intellectual
Property owned or licensed by the Company.

            (e) The Company has not made proprietary or non-public information
available to any person other than employees of the Company except pursuant to
written agreements requiring the recipients to maintain the confidentiality of
such information and appropriately restricting the use thereof. Neither the
Company nor any Majority Stockholder has knowledge of any infringement by others
of any Intellectual Property rights of the Company.

            (f) The present business, activities and products of the Company,
and, after giving effect to the Asset Transfer and the Closing, the LLC, do not
infringe any rights of any other person in Intellectual Property. No proceeding
charging the Company with infringement of any Intellectual Property of any other
person or entity has been filed or, to the knowledge of the Company and the
Majority Stockholders, is threatened to be filed. The Company is not making
unauthorized use of any confidential information or trade secrets of any person,
including without limitation, any former employer of any past or present
employee of the Company. Except as set forth in Schedule 3.14, neither the
Company nor, to the knowledge of the Company and the Majority Stockholders, any
of the Company's employees have any agreements or arrangements with any persons
other than the Company related to confidential information or trade secrets of
such persons or restricting any such employee's ability to engage in business
activities of any nature. The activities of the Company's employees on behalf of
the Company do not violate any such agreements or arrangements known to the
Company.

      3.15 Contracts. Except for those contracts, commitments, plans, agreements
and licenses described in Schedule 3.3, Schedule 3.6(a), Schedule 3.7, Schedule
3.14, Schedule 3.15 and Schedule 3.24 hereto (true and complete copies of which

the Asset Transfer, the LLC) without


                                       15
<PAGE>

      Each of the Contracts is valid and in full force and effect in accordance
with its respective terms, and there is not, under any Contract, an existing
material breach or event which, with the giving of notice or the lapse of time
or both, would become such a breach. The Company has complied with and is in
compliance with the client's guidelines and restrictions set forth in any
Contract described in Schedule 3.7, including, without limitation, any
limitation set forth in the applicable prospectus, offering memorandum or
marketing material for a fund or other collective investment vehicle or

Schedule 3.5 and, with respect to the Contract subject to any such consent,
Schedule 3.7, are obtained, and after giving effect to the Asset Transfer and
the Closing, each Contract will remain valid and effective in accordance with
its respective terms, and the LLC will be entitled to all rights and remedies
thereunder to which the Company is entitled on the date hereof, or such Contract
will have been replaced by a new contract with the same party or parties on
terms at least as favorable


                                       16
<PAGE>

to the LLC as the terms of the present Contract are to the Company. Neither the
Company nor the LLC is bound by any agreement, contract or arrangement which
could reasonably be expected to have a Material Adverse Effect of the Company,
the LLC or AMG.

      3.16 Litigation. Except as set forth in Schedule 3.16, there is no
litigation or legal or other action, suit, proceeding or, to the Company's and
the Majority Stockholders' knowledge, investigation, examination or audit, at
law or in equity, or before any federal, state, municipal or other governmental
department, commission, bureau, board, agency or instrumentality, domestic or
foreign (including, without limitation, any voluntary or involuntary proceedings
under the Bankruptcy Code or any action, suit, proceeding or investigation under
any federal or state securities law, rule or regulation), in which the Company,
the LLC, any Stockholder or any officer, director, stockholder, member or
employee of any such Person is a party or otherwise engaged, or to the knowledge
of the Company and the Majority Stockholders with which any of them is
threatened in connection with the business, affairs, properties or assets of the
Company or the LLC, or which might call into question the validity or hinder the
enforceability or performance of this Agreement, or of the other agreements,
documents and instruments contemplated hereby and the transactions contemplated
hereby and thereby. There are no proceedings pending or, to the knowledge of the
Company or any of the Majority Stockholders, threatened, relating to the

under any registrations or qualifications with various states or other
jurisdictions, or under any other Laws or Regulations.

or otherwise affecting the Company, the LLC or AMG. None of the Company, the LLC
or any Stockholder, nor any officer, director, member, employee or stockholder

or Rule 206(4)-4(b) thereunder, or ineligibility to serve as an associated
person of an

investment adviser, (ii) being ineligible to serve as an investment adviser (or
in any other capacity contemplated by the Investment Company Act) to a
registered investment company pursuant to Section 9(a) or 9(b) of the Investment
Company Act or (iii) being ineligible to serve as a broker-dealer or an
associated person of a broker-dealer pursuant to Section 15(b) of the Exchange
Act, and to the knowledge of the Company and the Majority Stockholders, there is
no proceeding or investigation that is reasonably likely to become the basis for
any such ineligibility, disqualification, denial, suspension or revocation. The
Company and each of its investment adviser representatives (as such term is
defined in Rule 203A-3(a) under the Advisers Act) has, and after giving effect
to the Closing and the Asset Transfer, the LLC and each of such representatives
will have, all permits, registrations, licenses, franchises, certifications and
other approvals (collectively, the "Licenses") required from foreign, federal,
state or local authorities in order for it to conduct the businesses presently
conducted by the Company in the manner presently conducted by the Company.
Neither the Company nor the LLC is subject to any limitation imposed in
connection with one or more of the Licenses which could reasonably be expected
to have a Material Adverse Effect on the Company and the LLC or AMG. Since
January 1, 1993, neither the Company nor the LLC has been a "broker" or "dealer"
within the meaning of the Exchange Act, and at no time since the Company's
inception has it been a "commodity pool operator" or "commodity trading adviser"
within the meaning of the Commodity Exchange Act. None of the Company or its
officers and employees is required to be registered as a broker or dealer, a
commodity trading adviser, a commodity pool operator, a futures commission
merchant, an introducing broker, a registered representative or associated
person, a counseling officer, an insurance agent, a sales person or in any
similar capacity with the SEC, the Commodity Futures Trading Commission, the
National Futures Association, the NASD or the securities commission of any state
or any self-regulatory body. Except as set forth on Schedule 3.18, no person
other than a full-time employee of the Company renders Investment Management
Services to or on behalf of clients of the Company or solicits clients with
respect to the provision of Investment Management Services by the Company.

      3.19 Insurance. The Company has in full force and effect such insurance as
is customarily maintained by companies of similar size in the same or a similar
business, with respect to its businesses, properties and assets (including,
without limitation, errors and omissions liability insurance), and all bonds
required by ERISA and by any contract or other agreement to which the Company is
a party, all as listed in Schedule 3.19 hereto. The Company is not in material
default under any such insurance policy. After giving effect to the Closing and
the Asset Transfer, each such insurance policy or equivalent policies will be in
full force and effect, with the LLC as the sole owner and beneficiary of each
such policy. Neither the Company nor any Majority Stockholder has knowledge of
circumstances which would cause any such insurance policy to fail to be renewed
on terms materially identical to those currently in effect.

      3.20 Powers of Attorney. None of the Company, the LLC or any Stockholder
(with respect to its Company Shares or any other interest in the Company or the
LLC) has any outstanding power of attorney.

      3.21 Finder's Fee. None of the Company, the LLC or any Stockholder has
incurred or become liable for any broker's commission, finder's fee or similar
payment relating to or in connection with the transactions contemplated by this
Agreement.


                                       19

      3.22 Corporate Records; Copies of Documents. The record books of the
Company accurately and completely record all corporate action taken by its
respective stockholders and board of directors and committees and true and
complete copies of the originals of such documents have been made available to
AMG for review. The Company has made available for inspection and copying by AMG
and its counsel true and complete copies of all documents referred to in this
Agreement or in the Schedules delivered to AMG in connection herewith.

      3.23 Transactions with Interested Persons. Neither the Company, the LLC,
nor any stockholder, member, officer, supervisory employee or director of the
Company or the LLC or, to the knowledge of the Company or any of the Majority
Stockholders, any of their respective spouses, other family members or
Affiliates, is or during the past three (3) years has been a party to any
material transaction or material contract or arrangement with the Company or the
LLC, or owns directly or indirectly on an individual or joint basis any interest
(excluding passive investments in the shares of any enterprise which are
publicly traded provided his or her holdings therein, together with any holdings
of his or her Affiliates and family members, are less than five percent (5%) of
the outstanding shares of comparable interest in such entity) in, or serves as
an employee, independent contractor, officer, director or in another similar
capacity of, any competitor or client of the Company, or any organization which
has or during the past three (3) years has had a material contract or
arrangement with the Company or the LLC (in each case, other than as expressly
contemplated hereby).

      3.24 Employee Benefit Programs.

            (a) Schedule 3.24 hereto lists every Employee Program (as defined
below) that has been maintained (as defined below) by the Company at any time
during the three-year period ending on the date of the Closing.

            (b) Each Employee Program which has ever been maintained by the
Company and which has at any time been intended to qualify under Section 401(a)
or 501(c)(9) of the Code has received a favorable determination or approval
letter from the IRS regarding its qualification under such section, and has in
fact been qualified in all material respects under the applicable section of the
Code from the effective date of such Employee Program through and including the
Closing (or, if earlier, the date that all of such Employee Program's assets
were distributed). No event or omission has occurred which could reasonably be
expected to cause any such Employee Program to lose its qualification under the
applicable Code section.

            (c) Each Employee Program has been established and administered in
accordance with its terms in all material respects, and is in compliance in all
material respects with the applicable provisions of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), the Code and other applicable
Laws and Regulations. With respect to any Employee Program ever maintained by
the Company, there has occurred no "prohibited transaction," as defined in
Section 406 of ERISA or Section 4975 of the Code, or breach of any duty under
ERISA or other applicable law (including, without limitation, any health care
continuation requirements or any other tax law requirements, or conditions to
favorable tax treatment, applicable to such plan), which could reasonably be
expected to result, directly or indirectly, in any taxes, penalties or other
liability to the Company, the LLC or AMG. No litigation, arbitration, or
governmental administrative proceeding


                                       20
<PAGE>

(or investigation) or other proceeding (other than those relating to routine
claims for benefits) is pending or, to the knowledge of the Company or any
Majority Stockholder, threatened with respect to any such Employee Program and
no facts or circumstances exist that could reasonably be expected to give rise
to any such litigation, arbitration or proceeding.

            (d) Neither the Company nor any ERISA Affiliate (as defined below)
(i) has ever maintained any Employee Program which has been subject to title IV
of ERISA (including, but not limited to, any Multiemployer Plan (as defined
below)) or (ii) has ever provided health care or any other non-pension benefits
to any employees after their employment is terminated (other than as required by
part 6 of subtitle B of title I of ERISA) or has ever promised to provide such
post-termination benefits.

            (e) With respect to each Employee Program maintained by the Company
within the three (3) years preceding the Closing, complete and correct copies of
the following documents (if applicable to such Employee Program) have previously
been delivered to AMG: (i) all documents embodying or governing such Employee
Program, and any funding medium for the Employee Program (including, without
limitation, trust agreements) as they may have been amended; (ii) the most
recent IRS determination or approval letter with respect to such Employee
Program under Code Sections 401 or 501(c)(9), and any applications for
determination or approval subsequently filed with the IRS; (iii) the three (3)
most recently filed IRS Forms 5500, with all applicable schedules and
accountants' opinions attached thereto; (iv) the summary plan description for
such Employee Program (or other descriptions of such Employee Program provided
to employees) and all modifications thereto; (v) any insurance policy (including
any fiduciary liability insurance policy) related to such Employee Program; (vi)
any documents evidencing any loan to an Employee Program that is a leveraged
employee stock ownership plan; and (vii) all other materials reasonably
necessary for AMG to perform any of its responsibilities with respect to any
Employee Program subsequent to the Closing (including, without limitation,
health care continuation requirements).

            (f) Each Employee Program listed on Schedule 3.24 may be amended,
terminated, modified or otherwise revised by the Company, including the
elimination of any and all future benefit accruals under any Employee Program.

            (g) For purposes of this section:

                  (i) "Employee Program" means (A) all employee benefit plans
      within the meaning of ERISA Section 3(3), including, but not limited to,
      multiple employer welfare arrangements (within the meaning of ERISA
      Section 3(4)), plans to which more than one unaffiliated employer
      contributes and employee benefit plans (such as foreign or excess benefit
      plans) which are not subject to ERISA; and (B) all employment agreements,
      stock option plans, bonus or incentive award plans, severance pay policies
      or agreements, change in control agreements, deferred compensation
      agreements, supplemental income arrangements, vacation plans, and all
      other employee benefit plans, agreements, and arrangements not described
      in (A) above. In the case of an Employee Program funded through an
      organization described in Code Section 501(c)(9), each reference to such
      Employee Program shall include a reference to such organization.


                                       21
<PAGE>

                  (ii) An entity "maintains" an Employee Program if such entity
      sponsors, contributes to, or provides (or has promised to provide)
      benefits under such Employee Program, or has any obligation (by agreement
      or under applicable law) to contribute to or provide benefits under such
      Employee Program, or if such Employee Program provides benefits to or
      otherwise covers employees or former employees of such entity, or their
      spouses, dependents, or beneficiaries.

                  (iii) An entity is an "ERISA Affiliate" of the Company if it
      would have ever been considered a single employer with the Company under
      ERISA Section 4001(b) or part of the same "controlled group" as the
      Company for purposes of ERISA Section 302(d)(8)(C).

                  (iv) "Multiemployer Plan" means a (pension or non-pension)
      employee benefit plan to which more than one employer contributes and
      which is maintained pursuant to one or more collective bargaining
      agreements.

      3.25 Directors, Officers and Employees.

            (a) Schedule 3.25(a) hereto contains a true and complete list of all
current directors and officers of the Company. In addition, Schedule 3.25(a)
hereto contains a list of all managers and employees of, and consultants to, the
Company who, individually, have received or are scheduled to receive
compensation from the Company and/or the LLC for the fiscal year ending December
31, 1998, in excess of $75,000. In each case such Schedule includes the current
job title of each such individual.

            (b) To the knowledge of the Company and the Majority Stockholders,
each employee listed in Schedule 3.25(b) hereto is in good health.

            (c) The Company employs and, upon giving effect to the Asset
Transfer, the LLC will employ immediately following the Asset Transfer,
approximately seventy (70) full-time employees and eight (8) part-time employees
and generally enjoys good employer-employee relationships. Except as set forth
in Schedule 3.25(c) hereto (or Schedule 3.24 hereto), neither the Company nor
the LLC has any obligation, contingent or otherwise, under (a) any employment,
collective bargaining or other labor agreement, (b) any written or oral
agreement containing severance or termination pay arrangements, (c) any deferred
compensation agreement, retainer or consulting arrangements, (d) any pension or
retirement plan, any bonus or profit-sharing plan, any stock option or stock
purchase plan, or (e) any other employee contract or non-terminable (whether
with or without penalty) employment arrangement (each an "Employment
Arrangement"). The Company is not in default with respect to any material term
or condition of any Employment Arrangement, nor will the Closing or the Asset
Transfer (or the transactions contemplated hereby or thereby) result in any such
default, including, without limitation, after the giving of notice, lapse of
time or both. The Company is not delinquent in payments to any of its employees
for any wages, salaries, commissions, bonuses or other direct compensation for
any services performed for it to the date hereof or amounts required to be
reimbursed to such employees. Upon termination of the employment of any of said
employees, none of the Company, the LLC or AMG could, by reason of the
transactions contemplated by this Agreement or anything done prior to the
Closing, be liable to


                                       22
<PAGE>

any of said employees for so-called "severance pay" or any other payments except
as set forth in the Restated LLC Agreement or the Employment Agreements. Neither
the Company nor the LLC has made any payments, is obligated to make any
payments, or is a party to any agreement that under certain circumstances could
obligate the Company, the LLC or AMG to make any payments, that would be
rendered non-deductible by Section 280G of the Code. The Company does not have
any policy, practice, plan or program of paying severance pay or any form of
severance compensation in connection with the termination of employment. Each of
the Company and the LLC is in compliance in all material respects with all
applicable Laws and Regulations respecting labor, employment, fair employment
practices, work place safety and health, terms and conditions of employment, and
wages and hours. There are no charges of employment discrimination or unfair
labor practices against or involving the Company. There are no grievances,
complaints or charges that have been filed against the Company under any dispute
resolution procedure that could have a Material Adverse Effect on the Company,
the LLC or AMG or the conduct of their respective businesses, and there is no
arbitration or similar proceeding pending and no claim therefor has been
asserted. The Company has in place all material employee policies required by
applicable laws, rules and regulations, and there have been no material
violations or alleged violations of any of such policies. The Company has not
received any notice indicating that any of its employment policies or practices
is currently being audited or investigated by any foreign, federal, state or
local government agency. Each of the Company and the LLC is, and at all times
since November 6, 1986 has been, in compliance with the requirements of the
Immigration Reform Control Act of 1986.

      3.26 Non-Foreign Status. No Stockholder is a "foreign person" within the
meaning of Section 1445 of the Code and Treasury Regulations Section 1.1445-2.

      3.27 Transfer of Shares. No holder of stock of the Company has at any time
transferred any of such stock to any employee of the Company, which transfer
constituted or could be viewed as compensation for services rendered to the
Company by said employee.

      3.28 Stock Repurchase. Except as set forth in Schedule 3.28, neither the
Company nor the LLC has redeemed or repurchased any of its capital stock or
interests since January 1, 1997.

      3.29 Code of Ethics; Insider Trading and Conflicts Policies; Wrap Account
Policies.

            (a) The Company has adopted a written policy regarding insider
trading and conflicts of interest and a Code of Ethics which complies and for at
least the past three (3) years has complied, in all material respects, with all
applicable provisions of Section 204A of the Advisers Act, a true and complete
copy of which has been delivered to AMG prior to the date hereof. All employees
of the Company have executed acknowledgments that they are bound by the
provisions of such Code of Ethics and insider trading and conflicts policies.
The policies of the Company with respect to avoiding conflicts of interest are
as set forth in the Company's most recent Form ADV or incorporated by reference
therein, and such disclosure is sufficient to comply with the requirements of
Form ADV. There have been no material violations or allegations of material
violations of such Code of Ethics, insider trading policy or conflicts policy.

            (b) The Company has had in effect for at least the past three (3)
years policies and procedures (copies of which have been provided to AMG,
including descriptions of any such


                                       23
<PAGE>

policies and procedures which are not written) regarding the establishment and
maintenance of Wrap Accounts which are and have been sufficient to address its
fiduciary obligations (if any) with respect to Wrap Accounts (including without
limitation matters relating to the suitability of such fee arrangements,
conflicts of interest arising in connection with such arrangements and similar
matters, to the extent applicable). The policies and procedures of the Company
with respect to Wrap Accounts are as set forth in the Company's most recent Form
ADV or incorporated by reference therein, and such disclosure is sufficient to
comply with the requirements of Form ADV.

      3.30 Disclosure. The representations, warranties and statements contained
in this Agreement and the agreements, documents, instruments, certificates,
exhibits and schedules delivered by the Company and the Stockholders to AMG
pursuant to this Agreement (the "Transaction Documents") or any Transaction
Documents, do not contain any untrue statement of a material fact, and, when
taken together, do not omit to state a material fact required to be stated
therein or necessary in order to make such representations, warranties or
statements not misleading in light of the circumstances under which they were
made. All consent solicitation materials to be prepared for use in connection
with the transactions contemplated by this Agreement at the time such

the time such information is disseminated, in each case, will be accurate and
complete, provided that no representation is made as to the accuracy or
completeness of written information supplied by AMG.

Schedule 3.3 hereto. The execution, delivery and performance of this Agreement
and each such agreement, document and instrument:

                  (i) does not and will not violate any Laws or Regulations, or
      require such Stockholder to obtain any approval, consent or waiver from,
      or make any filing with, any person or entity (governmental or otherwise)
      that has not been obtained or made; and

effect to the Closing and the Asset Transfer, the LLC), pursuant to an
investment advisory agreement between the Company (and, after giving effect to
the Closing and the Asset Transfer, the LLC) and a client thereof.

      4.5 Agreements.

            (a) Such Stockholder is not a party to any employment,
non-competition, trade secret or confidentiality agreement, arrangement or
understanding with any party other than the Company or the LLC. There are no

            (i) The Company and each of the Stockholders will join with AMG in
making an election under Section 338(h)(10) of the Code (and any corresponding

and sale of the stock of the Company hereunder through the Purchase (the
"Elections"). Each Stockholder will include his or her proportionate share of
any income, gain, loss, deduction or other tax item resulting from the Elections
on his or her Tax Returns to the extent required by applicable law. Each
Stockholder shall also pay his or her share of any Tax imposed on the Company or
the LLC or other successors in interest of the Company attributable to the
making of the Elections, including, but not limited to, (A) any Tax imposed
under Section 1374 of the Code, (B) any Tax imposed under Treasury Regulations
Section 1.338(h)(10)-1(e)(5), or (C) any state, local or foreign Tax imposed on
the Company's gain attributable to the Purchase or the Elections.

            (ii) The Stockholders and AMG agree that MADSP (as such term is
defined in Treasury Regulations Section 1.338(h)(10)-1(f)) for AMG's purchase of
the Company shall be allocated among the assets of the Company in accordance
with the provisions of Treasury Regulations Section 1.338(h)(10)-1(f). A
preliminary estimate of such allocation shall be agreed by AMG and the
Stockholders as soon as practicable after the date hereof. The final allocation
as of the date of the Closing (the "Asset Allocation") shall be agreed to by the
Stockholders and AMG as soon as practicable after the date of the Closing. If
the Stockholders and AMG are unable to agree on the Asset Allocation, such
allocation shall be determined on the basis of an appraisal prepared by the
Accounting Firm (as defined below). AMG shall prepare IRS Form 8023 (and any
required attachments ) and any similar state, local or foreign tax forms (and
any required attachments) required to make the Elections (collectively, the
"Election Forms" and each singularly, the "Election Form") and shall submit the
Election Forms to the Stockholders no later than sixty (60) days following the
date of the Closing. In the event of any dispute with regard to the content of
any Election Form (including any dispute concerning the Asset Allocation), the
parties shall diligently attempt to resolve such dispute. If they have not done
so within 15 days after the receipt of the Election Form by the Stockholders,
the dispute shall be resolved by a nationally recognized firm of independent
auditors acceptable to both the Majority Stockholders and to AMG (the
"Accounting Firm"), at least ten (10) days prior to the time the Election Form
is required to be filed. Each Stockholder shall promptly execute the applicable
Election Forms and shall return such Election Forms to AMG promptly and in any
event not less than five (5) days after the date on which the Election Form is
submitted to such Stockholder (following the final resolution of any issues
pursuant to the foregoing sentence). AMG shall file the Election Forms in
accordance with applicable Tax laws.

      6.2 Tax Periods Ending on or Before the Date of the Closing. The
Stockholders shall prepare or cause to be prepared and file or cause to be filed

Agreement)), and AMG shall cause the Company to cooperate in all reasonable
respects in the


                                       33

preparation of such Tax Returns. The Stockholders shall permit AMG to review and
comment on each such Tax Return described in the preceding sentence prior to
filing. To the extent required by applicable law, the Stockholders shall include
any income, gain, loss, deduction or other tax items for such periods on their
Tax Returns in a manner consistent with the Schedule K-1s furnished by the
Company to the Stockholders for such periods.

      6.3 Cooperation on Tax Matters.

            (i) The Stockholders and AMG shall report all transactions pursuant
to this Agreement in a manner that is consistent with the Elections and shall
take no position contrary thereto unless required to do so pursuant to a final
"determination" within the meaning of Section 1313 of the Code or an analogous
provision under state, local or foreign tax law.

            (ii) AMG, the Company and the Stockholders shall cooperate fully, as
and to the extent reasonably requested by the other party, in connection with
the filing of Tax Returns pursuant to this Section and any audit, litigation or
other proceeding with respect to Taxes. Such cooperation shall include the
retention and (upon the other party's request) the provision of records and
information which are reasonably relevant to any such audit, litigation or other
proceeding and making employees available on a mutually convenient basis to
provide additional information and explanation of any material provided
hereunder. The Company and the Stockholders agree (A) to retain all books and
records with respect to Tax matters pertinent to the Company and the LLC
relating to any taxable period beginning before the date of the Closing until
the expiration of the statute of limitations (and, to the extent notified by AMG
or the Stockholders, any extensions thereof) of the respective taxable periods,
and to abide by all record retention agreements entered into with any Taxing
Authority, and (B) to give the other party reasonable written notice prior to
transferring, destroying or discarding any such books and records and, if the
other party so requests, the Company or the Stockholders, as the case may be,
shall allow the other party to take possession of such books and records. AMG
and the Stockholders further agree, upon request, to use their best efforts to
obtain any certificate or other document from any governmental authority or any
other person as may be necessary to mitigate, reduce or eliminate any Tax that
could be imposed (including, but not limited to, with respect to the
transactions contemplated hereby).

      6.4 Tax Status. Between the date of this Agreement and the Closing, the
Company and the Stockholders shall keep in effect and not revoke the Company's
election to be taxed as an S corporation within the meaning of Sections 1361 and
1362 of the Code. Neither the Company nor any of the Stockholders shall take or
permit any action (other than the Purchase) that would result in the termination
of the Company's status as a validly existing S corporation within the meaning
of Sections 1361 and 1362 of the Code.

proceeding pending or, to its knowledge, threatened against AMG or, to AMG's
knowledge, investigations, at law or in equity, or before any federal, state,
municipal or other governmental department, commission, bureau, board, agency or
instrumentality, domestic or foreign (including, without limitation, any
voluntary or involuntary proceedings under the Bankruptcy Code or any action,
suit, proceeding or investigation under any Federal or state securities law,
rule or regulation), in which AMG or any officer, director, stockholder or
employee thereof is engaged or with which any of them is threatened, which would
prevent or hinder the consummation of the transactions contemplated by this

applicable, in all material respects, and no such Filing, as of the date of
filing, contained any untrue statement of a material fact or omitted to state a
material fact necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, except for any of the
foregoing which, individually or in the aggregate, would not reasonably be
expected to have a Material Adverse Affect on AMG and its Affiliates on a

      terms with respect to the compensation payable thereunder) which Advisory
      Contract is effective after giving effect to the Closing and the Asset

      client whose contract (including, in the case of Wrap Accounts, any
      Underlying Contract with such provisions) does not require written consent

      survive the transactions contemplated hereby, that the Company shall have
      obtained such consents as may be required under such contract (and any
      applicable Underlying Contract) and under applicable law (including, with
      respect to the requirement for contracts to include provisions requiring
      consent to transfer set forth under the Advisers Act, that the Company has
      complied with Section 5.2 hereof with respect to such contract).

      after giving effect to the Closing and the Asset Transfer, the LLC)
      (including without limitation by terminating or reducing its relationship
      with any applicable Introducing Agent) or to adjust the fee schedule with
      respect to one or more of its contracts (including any applicable
      Underlying Contract) in a manner that could materially reduce the fee to
      the LLC from that client or contract from that payable pursuant to the
      terms of the contract in effect with the Company on June 30, 1998 or the
      date hereof.

      the relevant Advisory Contract as of June 30, 1998 (adjusted for any
      additions and/or withdrawals by the client since June 30, 1998 and for any
      amendments to the fee schedule since such date determined through the
      Calculation Date), and (B) with respect to an advisory contract which is
      entered into after June 30, 1998, the annual advisory fees (other than
      incentive or performance fees) payable to the Company based on the fee
      schedule and assets under management set forth in the relevant agreement
      on the date of such agreement (adjusted for any additions and/or
      withdrawals by the client since that date and


                                       39
<PAGE>

for any amendments to the fee schedule since such date determined through the
Calculation Date).

in the manner now conducted by the Company, shall have been taken, made or
obtained, and any and all other material permits, approvals, consents, Licenses
or other actions necessary to consummate the transactions hereunder shall have

cease upon any termination pursuant to Section 11.1; provided, however, that (a)
the provisions of this Section 11, Sections 5.12, 5.13, 8.2 and the provisions
of Section 15 hereof shall survive any termination of this Agreement; (b)
nothing herein shall relieve any party from any liability for (i) any material

the date such representation or warranty was made, provided that no party shall
have liability for any material breach of representation or warranty unless such
party had actual knowledge of such breach at the time such representation or

business days prior to Closing, setting forth in reasonable detail the nature of

Stockholders proceed with the transactions contemplated hereby notwithstanding
the fact that one or more of the conditions specified in Section 10 hereof have

<PAGE>

specifically reflected or reserved for in the opening balance sheet of the LLC

schedule or exhibit delivered pursuant hereto or thereto, or otherwise in
connection with the transactions contemplated hereby; and

breach.

be subject to the following provisions:

            (a) No indemnification shall be payable pursuant to Sections
13.1(b), 13.1(c) or 13.2(b) to any AMG Indemnified Party, unless the total of
all claims for indemnification pursuant to Section 13.1 and 13.2 shall exceed

and provided, further, that, notwithstanding the provisions of Section 12.1, all
representations, warranties and covenants of the Company and the Stockholders
contained in this Agreement shall survive indefinitely for purposes of
indemnification sought pursuant to Sections 13.1(a) and 13.2(a); and

            (c) No indemnification shall be payable to the AMG Indemnified

            (e) No indemnification shall be payable to the AMG Indemnified

13.2(b)).

      13.4 Indemnification by AMG. AMG agrees to indemnify and hold the
Stockholders (individually a "Stockholder Indemnified Party" and collectively
the "Stockholder Indemnified Parties") harmless from and against any damages,
liabilities, losses, Taxes, fines, penalties, costs and expenses (including,
without limitation, reasonable fees and expenses of counsel) of any kind or
nature whatsoever (whether or not arising out of third-party claims and
including all amounts paid in investigation, defense or settlement of the
foregoing) which may be sustained or suffered by any of them arising out of or
based upon any of the following matters:

            (a) common law fraud by AMG in connection with any of its
representations, warranties or covenants under this Agreement or any agreement,
document or instrument contemplated hereby or in any certificate, schedule or
exhibit delivered pursuant hereto or thereto, or otherwise in connection with
the transactions contemplated hereby; and


                                       49
<PAGE>

            (b) any breach of any representation, warranty or covenant made by
AMG in this Agreement or in any agreement, document or instrument contemplated
hereby, or in any certificate, schedule or exhibit delivered pursuant hereto or
thereto, or by reason of any claim, action or proceeding asserted or instituted
growing out of any matter or thing constituting such a breach.

      13.5 Limitation on Indemnification by AMG. Notwithstanding the foregoing,
the right of Stockholder Indemnified Parties to indemnification under Section
13.4 shall be subject to the following provisions:

            (a) No indemnification pursuant to Section 13.4(b) shall be payable
to the Stockholders, unless the total of all claims for indemnification pursuant
to Section 13.4 shall exceed $500,000 in the aggregate, whereupon the full
amount of such claims shall be recoverable in accordance with the terms hereof;
and

            (b) No indemnification shall be payable to Stockholder Indemnified
Parties with respect to claims asserted pursuant to Section 13.4(b) above in
amounts in the aggregate in excess of $26.25 million.

            (c) No indemnification shall be payable to the Stockholders with
respect to claims asserted pursuant to Section 13.4(b) above after the
applicable Indemnification Cut-Off Date; provided, however, that such expiration
shall not affect any claim with respect to which notice was given in the manner
contemplated by Section 13.6 hereof prior to the Indemnification Cut-Off Date.

      13.6 Notice; Defense of Claims. An indemnified party may make claims for
indemnification hereunder by giving written notice thereof to the indemnifying
party within the period in which indemnification claims can be made hereunder.
If indemnification is sought for a claim or liability asserted by a third party,
the indemnified party shall also give written notice thereof to the indemnifying
party promptly after it receives notice of the claim or liability being
asserted, but the failure to do so shall not relieve the indemnifying party from
any liability except to the extent that it is prejudiced by the failure or delay
in giving such notice. Such notice shall reasonably summarize the bases for the
claim for indemnification and any claim or liability being asserted by a third
party. Within thirty (30) days after receiving such notice the indemnifying
party shall give written notice to the indemnified party stating whether it
disputes the claim for indemnification and whether it will defend against any
third party claim or liability at its own cost and expense. If the indemnifying
party fails to give notice that it disputes an indemnification claim within
thirty (30) days after receipt of notice thereof, it shall be deemed to have
accepted and agreed to the claim, which shall become immediately done and
payable. The indemnifying party shall be entitled to direct the defense against
a third party claim or liability with counsel selected by it (subject to the
consent of each indemnified party, which consent shall not be unreasonably
withheld) as long as the indemnifying party is conducting a good faith and
diligent defense. Each indemnified party shall at all times have the right to
fully participate in the defense of a third party claim or liability at its own
expense directly or through counsel; provided, however, that if the named
parties to the action or proceeding include either both the indemnifying party
and/or one or more indemnified parties and an indemnified party is advised that
representation of both parties by the same counsel would be inappropriate under
applicable standards of professional conduct, an indemnified party may engage
separate counsel at the expense of the indemnifying party. If no such notice of
intent to dispute and


                                       50
<PAGE>

defend a third party claim or liability is given by the indemnifying party, or
if such good faith and diligent defense is not being or ceases to be conducted
by the indemnifying party, the indemnified party shall have the right, at the
expense of the indemnifying party, to, after three (3) business days notice to
the indemnifying party of its intent to do so, undertake the defense of such
claim or liability (with counsel selected by the indemnified party), and to
compromise or settle it, exercising reasonable business judgment. If the third
party claim or liability is one that by its nature cannot be defended solely by
the indemnifying party, then the indemnified party shall make available such
information and assistance as the indemnifying party may reasonably request and
shall cooperate with the indemnifying party in such defense, at the expense of
the indemnifying party.

      13.7 Satisfaction of Stockholder Indemnification Obligations. In order to
satisfy the indemnification obligations of the Stockholders pursuant to Section
13.1 and 13.2 above, an AMG Indemnified Party shall have the right (in addition
to collecting directly from the Stockholders) to set off its indemnification
claims against (a) any and all amounts of interest and principal under any
promissory note issued to such Stockholder pursuant to the provisions of Section
3.11 of the Restated LLC Agreement (whether or not then due and payable) in
accordance with the terms of such note, and/or (b) any and all amounts to be
distributed to such Stockholder by the LLC, whether or not such right of set-off
is specifically provided for in the Restated LLC Agreement and/or (c) any and
all amounts owed or which become owed to such Stockholder or any Permitted
Transferee (as such term is defined in the Restated LLC Agreement) of such
Stockholder by AMG, the Company or the LLC pursuant to the provisions of
Sections 3.11 or 7.1 of the Restated LLC Agreement; provided, however, that,
absent a determination by an arbitrator or a court of competent jurisdiction
that such Stockholder is liable for such indemnification obligation, such right
of setoff shall not extend to any payments to such Stockholder to the extent
paid out of the LLC's Operating Allocation (as defined in the Restated LLC
Agreement).

      13.8 Other Indemnification Matters. The Stockholders and AMG agree to
treat any indemnity payment made pursuant to this Agreement as an adjustment to
the Purchase Price for federal, state, local and foreign income tax purposes. If
any indemnification payment under this Section 13 is determined to be taxable to
the indemnified party by any taxing authority, the indemnifying party will also
indemnify the indemnified party for any taxes incurred by reason of the receipt
of such payment and any increase paid pursuant to this Section 13.8, as well as
for related costs incurred by the indemnified party in connection with such
taxes (or any judgment or assessment, including the defense or settlement
thereof, relating to such taxes). Indemnification pursuant to this Article 13
shall be the exclusive remedy for monetary damages available to the Indemnified
Parties, other than for claims with respect to common law fraud.

accordance with Section 12 of the American Arbitration Association Commercial
Arbitration Rules who shall have substantial business experience in the
investment advisory industry, and shall otherwise be conducted in accordance
with the American Arbitration Association Commercial Arbitration Rules. The
parties covenant that they will participate in the arbitration in good faith and
that they will share equally its costs except as otherwise provided herein. The
provisions of this Section 15.2 shall be enforceable in any court of competent
jurisdiction, and the parties shall bear their own costs in the event of any
proceeding to enforce this Agreement except as otherwise provided herein. The
arbitrator may in his or her discretion assess costs and expenses (including the
reasonable legal fees and expenses of the prevailing party) against any party to
a proceeding. Any party unsuccessfully refusing to comply with an order of the
arbitrators shall be liable for costs and expenses, including attorney's fees,
incurred by the other party in enforcing the award.

      15.3 Waivers. Any waiver of any terms or conditions or of the breach of
any covenant, representation or warranty of this Agreement in any one instance,
shall not operate as or be deemed to be or construed as a further or continuing
waiver of any other breach of such term, condition, covenant, representation or
warranty or any other term, condition, covenant, representation or warranty, nor
shall any failure or delay at any time or times to enforce or require
performance of any provision hereof operate as a waiver of or affect in any
manner such party's right at a later time to enforce or require performance of
such provision or of any provision hereof; provided, however, that no such
waiver, unless it, by its own terms, explicitly provides to the contrary, shall
be construed to effect a continuing waiver of the provision being waived and no
such waiver in any instance shall


                                       56
<PAGE>

constitute a waiver in any other instance or for any other purpose or impair the
right of the party against whom such waiver is claimed in all other instances or
for all other purposes to require full compliance.

      15.4 Governing Law. This Agreement shall be construed under and governed
by the internal laws of the State of New York.

Exhibits referred to herein and the other writings specifically identified
herein or contemplated hereby, is complete, reflects the entire agreement of the
parties with respect to its subject matter, and supersedes all previous written
or oral negotiations, commitments and writings. No promises, representations,
understandings, warranties and agreements have been made by any of the parties
hereto except as referred to herein or in such Schedules and Exhibits or in such
other writings; and all inducements to the making of this Agreement and the
transactions contemplated hereby which were relied upon by either party hereto
have been expressed herein or in such Schedules or Exhibits or in such other
writings.

      15.7 Assignability; Binding Effect. This Agreement or any of the
obligations or rights hereunder (a) may not be assigned by AMG, without the
prior written consent of the Company, other than to an entity under the control
of AMG (for which such consent shall not be required), and (b) may not be
assigned by any of the Stockholders or the Company without the prior written
consent of AMG. This Agreement shall be binding upon and enforceable by, and
shall inure to the benefit of, the parties hereto and their respective
successors, heirs, executors, administrators and permitted assigns.

      15.8 Captions and Gender. The captions in this Agreement are for

      15.9 Execution in Counterparts. For the convenience of the parties and to
facilitate execution, this Agreement may (a) be executed in two or more
counterparts, each of which shall be deemed an original, but all of which shall
constitute one and the same document, and (b) executed by facsimile.

      15.10 Amendments. This Agreement may not be amended or modified, nor may
compliance with any condition or covenant set forth herein be waived, except by
a writing duly and validly executed by AMG and the Company, or in the case of a

thereof without the prior knowledge and written consent of AMG and

the Company, which consent shall not be unreasonably withheld, except as is
otherwise required by applicable laws, rules and regulations (including, without
limitation, the HSR Act, the Securities Act, the Exchange Act and the rules and
regulations promulgated thereunder).

      15.12 Consent to Jurisdiction. Each of the parties hereby consents to
personal jurisdiction, service of process and venue in the federal or state
courts of Massachusetts for any claim, suit or proceeding arising under this
Agreement and hereby irrevocably agrees that all claims in respect of such
action or proceeding may be heard and determined in such state's courts or, to
the extent permitted by law, in any federal court sitting in such state (in each
case subject to Section 15.2 hereof). Each of the parties hereby irrevocably
consents to the service of process in any such action or proceeding by the
mailing by certified mail of copies of any service or copies of the summons and
complaint and any other process to such party at the address specified in
Section 15.5 hereof. The parties agree that a final judgement in any such action
or proceeding shall be conclusive and may be enforced in other jurisdictions by
suit or in any other manner permitted by law and shall affect the right of a
party to service legal process or to bring any action or proceeding in the
courts of other jurisdictions.
