Item 5.  Other Events

     On January 6, 1999, Affiliated Managers Group, Inc. ("AMG") acquired a 65%
interest in Rorer Asset Management ("Rorer") with senior executives at Rorer
owning the remaining 35% interest. As a result of the transaction, Edward C.
Rorer & Co., Inc. (the predecessor company) was reorganized into Rorer Asset
Management LLC. AMG paid approximately $65 million in cash for its equity
position.

     This transaction will be accounted for under the purchase method of
accounting. AMG financed the purchase price out of borrowings under its existing
revolving credit facility.

     Founded in 1978, Rorer is a Philadelphia-based investment advisor that 
manages approximately $4.4 billion of assets. Rorer Asset Management provides 
investment services to a diverse client base including individuals, trusts 
and estates, corporations, pension and profit sharing plans, unions and 
Taft-Hartley funds, and charitable institutions. The firm offers three types 
of investment management accounts: large-cap equity, balanced, and fixed 
income. In addition, Rorer is introducing a mid-cap equity product employing 
the same relative value investment process that has been successfully applied 
to large-cap equities. The Rorer approach to asset management is a highly 
disciplined investment process which has provided competitive performance 
results with significantly less volatility than the market. These results are 
pursued by combining quantitative and qualitative disciplines in Rorer's 
stock selection models and adhering to them through market cycles.

                      ARTICLE III - MANAGEMENT OF THE LLC.

         SECTION 3.1 MANAGEMENT IN GENERAL.

         (a) Subject to the other terms and conditions of this Agreement,
including the delegations of power and authority set forth herein, the
management and control of the business of the LLC shall be vested exclusively in
the Manager Member, and the Manager Member shall have exclusive power and
authority, in the name of and on behalf of the LLC, to perform all acts and do
all things which, in its sole discretion, it deems necessary or desirable to
conduct the business of the LLC, with or without the vote or consent of the
Members in their capacity as such; PROVIDED, HOWEVER, that the Manager Member
shall not have the power to make investment recommendations to Clients on behalf
of the LLC, to execute, or cause the execution of, transactions in, or exercise
any powers or privileges with respect to, securities and other instruments in
accounts of clients of the LLC, which powers and privileges are hereby delegated
irrevocably and exclusively to the greatest extent permitted by applicable law
to the Management Committee pursuant to Section 3.2 hereof. Members, in their
capacity as such, shall have no right to amend or terminate this Agreement or to
appoint, select, vote for or remove the Manager Member, the Officers or their
agents or to exercise voting rights or call a meeting of the Members, except as
specifically provided in this Agreement. No Member other than the Manager Member
shall have the power to sign for or bind the LLC in its capacity as a Member,
but the Manager Member may delegate the power to sign for or bind the LLC to one
or more Officers (including without limitation through delegation to the
Management Committee).

         (b) The Manager Member shall, subject to all applicable provisions of
this Agreement and the Act, be authorized in the name of and on behalf of the
LLC: (i) to enter into, execute, amend, supplement, acknowledge and deliver any
and all contracts, agreements, leases or other instruments for the operation of
the LLC's business; and (ii) in general to do all things and execute all
documents necessary or appropriate to conduct the business of the LLC as set
forth in Section 2.7 hereof, or to protect and preserve the LLC's assets. The
Manager Member may delegate any or all of the foregoing powers to one or more of
the Officers.

         (c) The Manager Member is required to be a Member, and shall hold
office until its resignation in accordance with the provisions hereof. The
Manager Member is a "manager" (within the meaning of the Act) of the LLC. The
Manager Member shall devote such time to the business and affairs of the LLC as
it deems necessary, in its sole discretion, for the performance of its duties,
but in any event, shall not be required to devote full time to the performance
of such duties and may delegate its duties and responsibilities as provided in
Section 3.3.

         (d) Any action taken by the Manager Member, and the signature of the
Manager Member (or an authorized representative thereof) on any agreement,
contract, instrument or other 



                                       14
<PAGE>


document on behalf of the LLC, shall be sufficient to bind the LLC and shall
conclusively evidence the authority of the Manager Member and the LLC with
respect thereto.

         (e) Any Person dealing with the LLC, the Manager Member or any Member
may rely upon a certificate signed by the Manager Member as to (i) the identity
of the Manager Member or any Member; (ii) any factual matters relevant to the
affairs of the LLC; (iii) the Persons who are authorized to execute and deliver
any document on behalf of the LLC; or (iv) any action taken or omitted by the
LLC or the Manager Member.

                   SECTION 3.2 MANAGEMENT COMMITTEE OF THE LLC.

         (a) The LLC shall have a Management Committee (the "Management
Committee"). The Manager Member hereby delegates irrevocably and to the greatest
extent permitted by applicable law the exclusive power and authority under
Section 3.5(b) of this Agreement to the Management Committee to conduct the
day-to-day operations, business and activities of the LLC.

         (b) The Management Committee shall consist of Non-Manager Members
determined as follows:

                  (i) The Management Committee shall initially have four (4)
         members and shall initially consist of Messrs. Rorer, Hesser, Storms
         and Aronow; in the event Edward C. Rorer is no longer a member of the
         Management Committee, there shall thereafter be an odd number of
         members thereto. The number of members of the Management Committee may
         be increased by the Management Committee, with the written consent of
         the Manager Member, at any time. In addition, in the event that the
         Management Committee is deadlocked and unable to resolve any issue that
         is material, so long as he is a member of the Management Committee, Mr.
         Rorer's vote shall be deemed the vote of the Management Committee on
         that particular issue. No person who is not both an active employee of
         the LLC and a Non-Manager Member (an "Eligible Person") may be, become
         or remain a member of the Management Committee.

                  (ii) Any vacancy in the Management Committee however occurring
         (including a vacancy resulting from the increase in size of the
         Management Committee) may be filled by any other Eligible Person
         elected by a majority vote of the remaining members of the Management
         Committee with the written consent of the Manager Member. In lieu of
         filling any such vacancy, the Management Committee, by majority vote
         with the written consent of the Manager Member, may determine to reduce
         the number of members of the Management Committee, but not to a number
         less than three (3), provided that if at any time there are fewer than
         three (3) members of the Management Committee, such vacancies must be
         filled and, if they remain unfilled for a period of greater than five
         days, shall be filled by a majority vote of the remaining members of
         the Management Committee with the written consent of the Manager
         Member.



                                       15
<PAGE>


                  (iii) Members of the Management Committee shall remain members
         of the Management Committee until their resignation, removal or death.
         Any member of the Management Committee may resign by delivering his or
         her written resignation to any member of the Management Committee and
         the Manager Member. At any time that there are more than three (3)
         members of the Management Committee, any member of the Management
         Committee may be removed from such position: (A) with or without cause,
         by the Management Committee acting by a Committee Vote (with such
         Committee Vote being calculated for all purposes as if the member of
         the Management Committee whose removal is being considered were not a
         member of the Management Committee) with the written consent of the
         Manager Member, or (B) with or without cause, by the Non-Manager
         Members acting by a Majority Vote, with the written consent of the
         Manager Member or (C) For Cause by the Manager Member, with notice to
         the Management Committee specifying the reasons for the decision. Any
         Non-Manager Member shall be deemed to have resigned from the Management
         Committee and shall no longer be a member of the Management Committee
         immediately upon such Non-Manager Member ceasing to be an active
         employee of the LLC or otherwise ceasing to be a Non-Manager Member, in
         each case for any reason.

                  (iv) At any meeting of the Management Committee, presence in
         person or by telephone (or other electronic means) of a majority of the
         members of the Management Committee shall constitute a quorum. At any
         meeting of the Management Committee at which a quorum is present, a
         majority of the members of the Management Committee may take any action
         on behalf of the Management Committee (any such action taken by such
         members of the Management Committee is sometimes referred to herein as
         a "Committee Vote"). Any action required or permitted to be taken at
         any meeting of the Management Committee may be taken without a meeting
         of the Management Committee, if (A) a written consent thereto is signed
         by all the members of the Management Committee and (B) the Manager
         Member has been given a copy of such written consent not less than
         forty-eight (48) hours prior to such action. Notice of the time, date
         and place of all meetings of the Management Committee shall be given to
         all members of the Management Committee and the Manager Member at least
         forty-eight (48) hours in advance of the meeting. A representative of
         the Manager Member shall be entitled to attend each meeting of the
         Management Committee. Notice need not be given to any member of the
         Management Committee or the Manager Member if a waiver of notice is
         given (orally or in writing) by such member of the Management Committee
         or the Manager Member (as applicable), before, at or after the meeting.
         Members of the Management Committee are not "managers" (within the
         meaning of the Act) of the LLC.

                  (v) Notwithstanding any other provision hereof to the
         contrary, the Manager Member shall have full power and authority at any
         time in its sole discretion (and without the consent or approval of the
         Management Committee or the Non-Manager Members) to increase the number
         of members of the Management Committee and to fill the vacancies
         created by any such increase with one or more other Non-



                                       16
<PAGE>


         Manager Members or with other persons selected by the Manager Member,
         provided that such increase may only be effected by written notice from
         the Manager Member to the LLC, which written notice must expressly
         reference this Section of this Agreement.

         SECTION 3.3 OFFICERS OF THE LLC. The Management Committee may designate
employees of the LLC as officers of the LLC (the "Officers") as it deems
necessary or desirable to carry on the business of the LLC. The Management
Committee may delegate any of its power or authority to an Officer or Officers
subject to modification and withdrawal of such delegated power and authority by
the Management Committee. Any two or more offices may be held by the same
person. New offices may be created and filled by the Management Committee. Each
Officer shall hold office until his or her successor is designated by the
Management Committee or until his or her earlier death, resignation or removal.
Any Officer may resign at any time upon written notice to the LLC and the
Manager Member. Any Officer designated by the Management Committee may be
removed from his or her office (with or without a concurrent termination of
employment) (i) with or without cause by the Management Committee (excluding for
all purposes the Person being considered) or (ii) For Cause by the Manager
Member, in each case at any time, subject to the terms of such Officer's
Employment Agreement with the LLC, if any. A vacancy in any office occurring
because of death, resignation, removal or otherwise may be filled by the
Management Committee. Any designation of Officers, a description of any duties
delegated to such Officers, and any removal of such Officers by the Management
Committee, shall be approved by the Management Committee in writing, which
approval shall be delivered to the Manager Member. The Officers are not
"managers" (within the meaning of the Act) of the LLC.

         SECTION 3.4 EMPLOYEES OF THE LLC.

         (a) The decision to employ and the terms of employment of any employee
of the LLC who is not a Non-Manager Member (including, without limitation, with
respect to the hiring, all aspects of compensation, promoting, demoting and
terminating of such employees), shall be determined by the Management Committee
or such Person or Persons to whom the Management Committee may delegate such
power and authority (subject, in all instances, to the power of the Management
Committee to revoke such delegation in whole or in part (by a Committee Vote
that excludes any Person to whom such power and authority has been delegated)),
subject, in all cases, to compliance with all applicable laws, rules and
regulations and with the provisions of Section 3.5 hereof. Notwithstanding the
foregoing, the Manager Member may terminate the employment by the LLC of any
employee who has engaged in any activity included in the definition of "For
Cause," with notice to the Management Committee specifying the reasons for such
decision.

         (b) The granting or Transferring of LLC Interests in connection with
any hiring or promotion of an employee shall be subject to the terms and
conditions set forth in Articles V and VI hereof.

         (c) Any Person who is a Non-Manager Member may have his or her
employment with the LLC terminated by the LLC only: (i) in the case of a
termination For Cause, either by the Manager Member or by the Management
Committee (excluding for all purposes the Person whose termination is being
considered) with the prior written consent of the Manager Member, or (ii) in 



                                       17
<PAGE>


the case of any other termination by the LLC, by the Management Committee
(excluding for all purposes the Person whose termination is being considered),
with the prior written consent of the Manager Member.

         SECTION 3.5 OPERATION OF THE BUSINESS OF THE LLC.

         (a) Subject to the terms hereof, the Management Committee is hereby
delegated irrevocably the exclusive power and authority to execute, or cause the
execution of, transactions in, and to exercise all rights, powers and privileges
with respect to, securities and other instruments in accounts of clients of the
LLC, which power and authority may be delegated to the Officers of the LLC from
time to time in the discretion of the Management Committee.

         (b) Subject to the Manager Member's rights, duties and obligations set
forth in the Act and elsewhere in this Agreement (including, without limitation,
the provisions of this Section 3.5) the Management Committee is hereby delegated
irrevocably and to the greatest extent permitted by applicable law the exclusive
power and authority from the Manager Member to manage the day-to-day operations,
business and activities of the LLC; including, without limitation, the exclusive
power and authority, in the name of and on behalf of the LLC, to:

                  (i) determine the use of the Operating Allocation as set forth
         in Section 3.5(c) below;

                  (ii) execute such documents and do such acts as are necessary
         to register (or provide or qualify for exemptions from any such
         registrations) or qualify the LLC under applicable federal and state
         securities laws;

                  (iii) enter into contracts and other agreements with respect
         to the provision of Investment Management Services and execute other
         instruments, documents or reports on behalf of the LLC in connection
         therewith;

                  (iv) enter into contracts, agreements and commitments with
         respect to the operation of the business of the LLC as are consistent
         with the other provisions of this Agreement and the Act; and

                  (v) act for and on behalf of the LLC in all matters incidental
         to the foregoing and other day-to-day matters.



                                       18

         (c) The Operating Allocation of the LLC for any period shall be used by
the LLC to provide for and pay its business expenses and expenditures as
determined by the Management Committee; including, without limitation,
compensation and benefits to its employees, including the Officers, and at the
discretion of the Management Committee, establishing reserves for future such
payments. Without the prior written consent of the Manager Member (which written
consent makes specific reference to this Section 3.5(c)), the LLC shall not
incur (and the Employee Stockholders shall use commercially reasonable efforts
to prevent the LLC from incurring) any expenses or take any action to incur
other obligations which expenses and obligations exceed the ability of the LLC
to pay or provide for them out of its Operating Allocation on a current or
previously reserved basis; provided, however, that the LLC may make any payments
required to be made pursuant to that certain License Agreement between the LLC
and the Manager Member of even date herewith (the "License Agreement")
notwithstanding the limitation set forth in this sentence. Except to the extent
otherwise required by applicable law, the LLC shall only make payments of
compensation (including bonuses) to its employees (including any Officers) out
of the balance of its Operating Allocation remaining after the payment (or
reservation for payment) of all the other business expenses and expenditures for
the applicable period. Any excess Operating Allocation remaining for any fiscal
year following the payment (or reservation for payment) of all business expenses
and expenditures including any amount established as a reserve in a prior period
reasonably determined to have been in excess of what was necessary for such
reserve, may be used by the LLC in such fiscal year and/or in future fiscal
years in accordance with the preceding sentence. The Owners' Allocation may be
used to provide for and pay the business expenses of the LLC only (i) to the
extent specified in Section 3.5(e) with respect to key-man life insurance and
disability insurance, Section 4.3 with respect to certain extraordinary expenses
and as otherwise agreed to in writing by the Manager Member and the Non-Manager
Members acting by a Majority Vote (any such use being referred to herein as an
the "Owners' Allocation Expenditure") and (ii) to the extent specified in the
proviso contained in the second sentence of this Section 3.5(c) (with any such
use not constituting an Owners' Allocation Expenditure).

         For purposes of this Agreement and notwithstanding any contrary
treatment required by the LLC or AMG for financial reporting purposes, any
expenses paid utilizing funds provided to the LLC by the Stockholders (as
defined in the Stock Purchase Agreement) by reason of indemnification
obligations under Section 13.1 of the Stock Purchase Agreement (however
provided, including pursuant to one of the off-set mechanisms specified in
Section 13.6 thereof resulting in such funds being retained by the LLC), shall
not be paid for from the Operating Allocation (and if previously so paid or
reserved for such calculation and treatment shall be reversed) and shall not
constitute business expenditures or actual expenses of the LLC or Revenues from
Operations hereunder.

         (d) The LLC shall not do or commit to do, and the Employee Stockholders
and Non-Manager Members shall use all commercially reasonable efforts to prevent
the LLC from doing or committing to do, any of the following without the prior
written consent of the Manager Member (which written consent makes specific
reference to this Section 3.5(d)):

                  (i) enter into, amend, modify or terminate any contract,
         agreement or understanding (written or oral) if such action or the
         resulting contract, agreement or understanding could reasonably be
         expected to conflict with the provisions of this Section 3.5;



                                       19
<PAGE>


                  (ii) enter into, amend, modify or terminate any contract,
         agreement or understanding (written or oral) if such action or the
         resulting contract, agreement or understanding (individually or in the
         aggregate) could reasonably be expected to have a material adverse
         impact on the availability of the Operating Allocation of the LLC in
         future periods (including, without limitation, long-term leases or
         employment contracts);

                  (iii) enter into, amend, modify or terminate any contract,
         agreement or understanding (written or oral) if such action or the
         resulting contract, agreement or understanding has the effect of
         creating a Lien upon any of the assets of the LLC (other than Liens
         securing indebtedness of the LLC incurred to finance the acquisition of
         fixed or capital assets (whether pursuant to a deferred purchase
         agreement with a vendor, a loan, a financing lease or otherwise),
         provided that (A) such Liens shall be created substantially
         simultaneously with the acquisition of such fixed or capital assets,
         (B) such Liens do not at any time encumber any property other than
         property financed by such indebtedness, (C) the amount of indebtedness
         secured thereby is not increased and (D) the principal amount of
         indebtedness secured by such Lien shall at no time exceed the purchase
         price of such property) or upon any of that portion of the revenues of
         the LLC which is included in the Owners' Allocation (other than with
         respect to permitted Owners' Allocation Expenditures hereunder);

                  (iv) take any action (or omit to take any action) if such
         action (or omission) could reasonably be expected to result in the
         termination of the employment by the LLC of any Employee Stockholder
         (provided that the foregoing shall not impose any limitation on the
         ability of an Employee Stockholder to terminate his or her employment
         with the LLC in accordance with the provisions hereof and any
         applicable Employment Agreement, and shall not require the LLC to pay
         additional compensation to retain the services of any Employee
         Stockholder);

                  (v) create, incur, assume, or suffer to exist any Indebtedness
         (other than Indebtedness in an amount not to exceed in aggregate
         principal amount $250,000 outstanding at any time incurred to finance
         the acquisition of fixed or capital assets (whether pursuant to a
         deferred purchase agreement with a vendor, a loan, a financing lease or
         otherwise), provided that (A) such Indebtedness shall be created
         substantially simultaneously with the acquisition of such fixed or
         capital assets, (B) the amount of such Indebtedness shall not
         thereafter be increased and (C) the principal amount of such
         Indebtedness shall at no time exceed the purchase price of such fixed
         or capital assets);

                  (vi) establish or modify any material compensation arrangement
         (other than salary and cash bonuses in the ordinary course) or program
         (whether cash or non-cash benefits) applicable to any employee, in any
         such case which is subject to ERISA, which requires qualification under
         the Code, or which otherwise (A) requires the Manager Member (other
         than in its capacity as Manager Member) or any of its Affiliates to
         take any action which it would not take but for the action contemplated

         (e) The LLC will maintain (and the Management Committee shall use all
commercially reasonable efforts to cause the LLC to maintain), in full force and
effect, such insurance as is customarily maintained by companies of similar size
in the same or similar businesses (including, without limitation, errors and
omissions liability insurance), the premiums on which will be paid out of the
Operating Allocation. The LLC will maintain such key-man life insurance and
disability insurance policies on each Employee Stockholder as the Manager Member
shall deem necessary or desirable, from time to time, and the Employee
Stockholders and Management Committee will use all commercially reasonable
efforts to effectuate the foregoing. The LLC will receive the proceeds of the
above-referenced insurance policies, and the Members agree with each other and
the LLC that the LLC will pay the premiums on such key-man life and disability
policies out of the Owners' Allocation.

         (f) In addition to, and not in limitation of, the Manager Member's
powers and authority under this Agreement (including, without limitation,
pursuant to Section 3.1(a) hereof), the Manager Member shall also have the
power, in its sole discretion (after consultation with the Management Committee,
to the extent practicable) whether or not they involve day-to-day operations,
business and activities of the LLC, to take any or all of the following actions:

                  (i) such actions as it deems necessary or appropriate to cause
         the LLC or any Affiliate of the LLC, or any officer, employee, member,
         partner, or agent thereof, to comply with applicable laws, rules or
         regulations;

                  (ii) such actions as it deems necessary or appropriate to
         coordinate any initiative which could materially affect the Manager
         Member, AMG and/or any of its Affiliates but only on such terms and
         conditions as the participation of the LLC in such initiative has been
         approved by the Management Committee;

                  (iii) such actions as it deems necessary or appropriate to
         cause the LLC to fulfill its obligations and exercise its rights under
         the Stock Purchase Agreement and this Agreement; and

                  (iv) any other action necessary or appropriate to prevent
         actions that require the Manager Member's consent pursuant to the terms
         of this Agreement if such consent has not then been given.

         (g) Notwithstanding any of the provisions of this Agreement to the
contrary, all accounting, financial reporting and bookkeeping procedures of the
LLC shall be established in conjunction with policies and procedures determined
under the supervision of the Manager Member. The LLC shall have a continuing
obligation to keep AMG's chief financial officer informed of material financial
developments with respect to the LLC. Notwithstanding any of the provisions of
this Agreement to the contrary, all legal, compliance and regulatory matters of
the LLC shall be coordinated with the Manager Member and/or its Affiliates, and
the LLC's legal compliance activities shall be conducted and established in
conjunction with policies and procedures determined under the supervision of the
Manager Member. Each Employee Stockholder and Non-Manager Member covenants and
agrees that such Employee Stockholder or Non-Manager Member will at all times
conduct its activities in connection with the LLC and any services provided to
the LLC in accordance with all applicable laws, rules and regulations, and that
it will use all commercially 



                                       22
<PAGE>


reasonable efforts to ensure that the business and activities of the LLC are
conducted in compliance with all applicable laws, rules and regulations in all
material respects and (ii) to preserve the goodwill and franchise value of the
LLC.

         (h) Notwithstanding any of the provisions of this Agreement to the
contrary, the Manager Member shall have the power to establish and mandate that
the LLC participate in employee benefit plans which are subject to ERISA or
require qualification under Section 401 of the Internal Revenue Code to the
extent necessary in order to make the expenses of any such plan(s) deductible or
otherwise to comply with ERISA or the Code, and may establish or modify the
terms of any such plan to the extent necessary in connection therewith, provided
that any such action taken by the Manager Member shall treat the Affiliates of
the Manager Member subject to such action in an equitable manner (i.e., a manner
not materially more disadvantageous to one Affiliate than to other Affiliates of
the Manager Member, as reasonably determined by the Manager Member) to the
extent permissible under ERISA and the Code and consistent with achieving tax
deductibility.

         (i) Notwithstanding any of the provisions of this Agreement to the
contrary, the Management Committee and Employee Stockholders of the LLC will
cooperate with the Manager Member and its Affiliates in implementing any
initiative generally involving the LLC and a number of such Affiliates but only
on such terms and conditions as the participation of the LLC in such initiative
has been approved by the Management Committee.

         SECTION 3.6 COMPENSATION AND EXPENSES OF THE MEMBERS. The Manager
Member may receive compensation for services provided to the LLC only to the
extent approved by the Management Committee. The LLC shall, however, pay and/or
reimburse the Manager Member for extraordinary expenses incurred by the Manager
Member or AMG directly in connection with the operation of the LLC. It is
expressly understood by the parties hereto that the Manager Member's general
overhead items and expenses (including, without limitation, salaries, rent and
travel expenses) shall not be reimbursed by the LLC. Stockholders, officers,
directors, Members and agents of Members may serve as employees of the LLC and
be compensated therefor out of the Operating Allocation as determined by the
Management Committee (or its delegate(s)) pursuant to Section 3.5(c)). Except in
respect of their provision of services as employees of the LLC for which they
may be compensated out of the Operating Allocation as contemplated by the
preceding sentence, Non-Manager Members and members of their Immediate Family
may not receive compensation on account of the provision of services to the LLC.

         SECTION 3.7 OTHER BUSINESS OF THE MANAGER MEMBER AND ITS AFFILIATES.
The Manager Member, AMG and their respective Affiliates may engage,
independently or with others, in other business ventures of every nature and
description, including the acquisition, creation, financing, trading in, and
operation and disposition of interests in, investment managers and other
businesses that may be competitive with the LLC's business. Neither the LLC nor
any of the Non-Manager Members shall have any right in or to any other such
ventures by virtue of this Agreement or the limited liability company created or
continued hereby, nor shall any such activity by the Manager Member, AMG or such
Affiliates in and of itself be deemed wrongful or improper or result in any
liability of the Manager Member, AMG or such Affiliates. None of the Manager
Member, AMG or any of their Affiliates shall be obligated to present any
opportunity to the LLC even if such opportunity is of such a character which, if
presented to the LLC, would be suitable for the LLC. Neither the Manager Member
nor AMG shall disclose any Intellectual Property owned or used in 



                                       23
<PAGE>


the course of business by the LLC to any Person, including, without limitation ,
any Affiliate, and each of the Manager Member and AMG agrees always to keep
secret and not ever to publish, divulge, furnish, use or make accessible to
anyone any Intellectual Property that is not otherwise publicly available (other
than Intellectual Property that is publicly available by virtue of a breach of
the provisions of this Section 3.7), in each case other than in the regular
business of the LLC and its Controlled Affiliates, as required by court order or
by law or in connection with the enforcement of this Agreement or the Stock
Purchase Agreement.

         SECTION 3.8 NON-MANAGER MEMBERS AND NON-SOLICITATION AGREEMENTS. Each
Employee Stockholder and, if there is one, the Non-Manager Member of which it is
a stockholder (its Non-Manager Member), has provided the LLC with either (a) an
Employment Agreement with the LLC,or (b) a Non-Solicitation/Non-Disclosure
Agreement in form and substance substantially similar to EXHIBIT B hereto (the
"Non-Solicitation Agreement") (and, in the case of any substitute Non-Manager
Member (pursuant to Section 5.2 hereof) or Additional Non-Manager Member (as
defined in Section 5.5 hereof) which is not already bound by a Non-Solicitation
Agreement, it shall, prior to and as a condition precedent to becoming a
Non-Manager Member, provide the LLC with such an agreement (together with any
changes or modifications thereto as the Manager Member may deem necessary or
desirable) and such agreements do and shall, at all times, provide that each of
the LLC and the Manager Member shall be entitled to enforce the provisions of
such agreements on its own behalf and that the Management Committee or the
Manager Member shall be entitled to enforce the provisions of such agreements on
behalf of the LLC.

         SECTION 3.9 NON-SOLICITATION AND NON-DISCLOSURE BY NON-MANAGER MEMBERS
AND EMPLOYEE STOCKHOLDERS.

         (a) Each Non-Manager Member and each Employee Stockholder agrees, for
the benefit of the LLC and the other Members, that such Non-Manager Member and
such Employee Stockholder shall not, while employed by the LLC or any of its
Affiliates, engage in any Prohibited Competition Activity.

         (b) In addition to, and not in limitation of, the provisions of Section
3.9(a) hereto, each Non-Manager Member and each Employee Stockholder agrees, for

Manager Member and the Management Committee, directly or indirectly, whether as

employee, agent or consultant, or in any other capacity, on behalf of himself or
any firm, corporation or other business organization other than the LLC and its

<PAGE>


                  (ii) solicit or induce, whether directly or indirectly, any
         Person for the purpose (which need not be the sole or primary purpose)
         of (A) causing any funds with respect to which the LLC or any of its
         Controlled Affiliates provides Investment Management Services to be
         withdrawn from such management, or (B) causing any Client of the LLC
         (including any Potential Client) not to engage the LLC or any of its
         Controlled Affiliates to provide Investment Management Services for any
         additional funds;

                  (iii) contact or communicate with, in either case in

         clients of the LLC (including Potential Clients) who are also members
         of the Immediate Family of the Employee Stockholder; or

                  (iv) solicit or induce, or attempt to solicit or induce,
         directly or indirectly, any employee or agent of, or consultant to, the

         Controlled Affiliates who was employed by or acted as an agent or
         consultant to the LLC (or its predecessor Edward C. Rorer & Co., Inc.
         or any predecessor thereto) or their respective Controlled Affiliates
         at any time during the two (2) year period preceding the termination of
         the Employee Stockholder's employment (excluding for all purposes of
         this sentence, secretaries and persons holding other similar
         positions).

For purposes of this Section 3.9(b), (x) the term "Past Client" shall be limited
to those past Clients who were recipients of Investment Management Services,
directly or indirectly, from, the LLC (including its predecessor, Edward C.
Rorer & Co., Inc. or any predecessor thereto) and/or their respective Controlled
Affiliates at the date of termination of the Employee Stockholder's employment
or at any time during the two (2) years immediately preceding the date of such
termination; and (y) the term "Potential Client" shall be limited to those
Persons to whom an offer was made (or other requisite action was taken) within

Notwithstanding the provisions of Sections 3.9(a) and 3.9(b), any Employee
Stockholder may make passive investments in an enterprise which is competitive
with AMG or the LLC the shares or other equity interests of which are publicly
traded provided his holding therein together with any holdings of his Affiliates
and members of his Immediate Family, are, at the time such investments are made,
less than five percent (5%) of the outstanding shares or comparable interests in
such entity.

         (c) Each Member and each Employee Stockholder agrees that any and all
presently existing investment advisory businesses of the LLC and its Controlled

business, and any combinations or variations thereof and all related logos, are
and shall be the exclusive property of the LLC or such Controlled Affiliate, as

directly to the LLC or such Controlled Affiliate. In addition, each Member and
each Employee Stockholder acknowledges and agrees that the investment
performance of the accounts managed by the LLC (and its predecessor, Edward C.
Rorer & Co., Inc. or any predecessor thereto) was attributable to the efforts of
the team of professionals of the LLC (or its predecessor, Edward C. Rorer & Co.,
Inc. or any predecessor thereto, as applicable) and not to the efforts of any
single individual or subset of such team of professionals, and that therefore,
the performance records of the accounts managed by the LLC (and its predecessor,
Edward C. Rorer & Co., Inc. and any predecessor thereto) are and shall be the
exclusive property of the LLC.

publish, divulge, furnish, use or make accessible to anyone (otherwise than in
the regular business of the LLC and its Controlled Affiliates or as required
bycourt order or by law (on the written advice of outside counsel)) any
Intellectual Property of the LLC or any Controlled Affiliate thereof unless such
information can be shown to be in the public domain through no fault of such
Non-Manager Member or Employee Stockholder. At the termination of the Employee
Stockholder's services to the LLC, all data, memoranda, client lists, notes,
programs andother papers, items and tangible media, and reproductions thereof
relating to the foregoing matters in the Non-Manager Member's or Employee
Stockholder's possession or control, shall be returned to the LLC and remain in
its possession. Any Person who becomes a Non-Manager Member of the LLC, or who
acquires a beneficial interest in an entity which is a Non-Manager Member of the
LLC, and does not enter into a Non-Solicitation/Non-Disclosure Agreement in the
form attached hereto as Exhibit B shall not be provided access to any
confidential or proprietary information of the LLC (except to the extent as may
be otherwise required by applicable law).

         (e) Each Non-Manager Member and each Employee Stockholder acknowledges
that, in the course of entering into this Agreement, the Non-Manager Member and
the Employee Stockholder have had and, in the course of the operation of the
LLC, the Non-Manager Member and Employee Stockholder will from time to time
have, access to Intellectual Property owned by or used in the course of business
by AMG. Each Non-Manager Member and each Employee Stockholder agrees, for the
benefit of the LLC and its Members, and for the benefit of the Manager Member

accessible to anyone (otherwise than at the Manager Member's request or by court
order or by law (on the written advice of outside counsel)) any knowledge or
information regarding Intellectual Property (including, by way of example and
not of limitation, the transaction structures utilized by AMG) of AMG unless
such information can be shown to be in the public domain through no fault of
such Non-Manager Member or Employee Stockholder. At the termination of the
Employee Stockholder's service to the LLC, all data, memoranda, documents, notes
and other papers, items and tangible media, and reproductions thereof relating
to the foregoing matters in the Non-Manager Member's or Employee Stockholder's
possession or control shall be returned to AMG and remain in its possession.

         (f) The provisions of this Section 3.9 shall not be deemed to limit any
of the rights of the LLC or the Members under any of the Employment Agreements,
Non-Solicitation Agreements or under applicable law, but shall be in addition to
the rights set forth in each of the Employment Agreements and Non- Solicitation
Agreements, and those which arise under applicable law.

         SECTION 3.10 REMEDIES UPON BREACH.

         (a) In the event that a Non-Manager Member or its Employee Stockholder
(i) breaches any of the provisions of Section 3.9 hereof, or (ii) breaches any
of the non-competition or non-solicitation provisions of the Employment
Agreement or Non-Solicitation Agreement to which it or he is a party (in each
case, including, without limitation, following the termination of his or her
employment with the LLC), then (A) such Non-Manager Member shall forfeit its
right to receive any payment for its LLC Interests under Section 3.11, although
it shall cease to be a Non-Manager Member in accordance with the provisions of
Section 3.11(e) and (B) AMG (or its assignees) shall have no further obligations
under any promissory note theretofore issued to such Non-Manager Member pursuant
to Section 3.11(f) and (C) the LLC shall be entitled to withhold any other
payments to which such Non-Manager Member otherwise would be entitled to offset
damages resulting from such breach; provided, however, that, absent a
determination by an arbitrator or a court of competent jurisdiction that such
Non-Manager Memberhas so breached any of such provisions, such right of setoff
shall not extend to any payments to the Non-Manager Member to the extent paid
out of the Operating Allocation of the LLC.

         (b) Each Non-Manager Member and each Employee Stockholder agrees that
any breach of the provisions of Section 3.9 of this Agreement or of the
provisions of the Employment Agreement or Non- Solicitation Agreement by such
Non-Manager Member or Employee Stockholder could cause irreparable damage to the
LLC and the other Members, and that the LLC (by action of the Management
Committee) and/or the Manager Member, shall have the right to an injunction or
other equitable relief (in addition to other legal remedies) to prevent any

                  Employee Stockholder, the LLC shall purchase and the
                  Non-Manager Member (or the Non-Manager Member of which such

                  as applicable, maintained by the LLC on the life or health of
                  such Employee Stockholder, net of any tax liability expected

                  3.11(a) (determined after all such proceeds have been

                  LLC Interests held by the Repurchased Member, in each case,

                  hereof, each LLC Repurchase and each Manager Member Repurchase
                  together with the related LLC Repurchase, if any, is referred
                  to as a "Repurchase."

                  (b) The closing of the Repurchase will take place on a date
set by the Manager Member (the "Repurchase Closing Date") which shall be after
the last day of the calendar quarter in which the Employee Stockholder's
employment with the LLC is terminated but which is not more than one hundred
twenty (120) days after the date on which the termination of the employment by
the LLC of the relevant Employee Stockholder occurred; PROVIDED, HOWEVER, that
(i) if the employment by the LLC of such Employee Stockholder is terminated
because of the death or Permanent Incapacity of such Employee Stockholder, then
the Repurchase Closing Date shall be a date set by the Manager Member which is
as soon as reasonably practicable after the later of (A) one hundred twenty
(120) days after the death or Permanent Incapacity, as applicable, of such
Employee Stockholder or (B) thirty (30) days after the LLC has received the
proceeds of all key-man life insurance policies or disability insurance
policies, as applicable, maintained by the LLC on the life or health of such
Employee Stockholder.

                  (c) The purchase price for the Repurchase (the "Repurchase
Price") shall be determined as follows:

                           (i) If the Employee Stockholder's employment with the
                  LLC is terminated because of the death, Permanent Incapacity
                  or Retirement of the Employee Stockholder or if such Employee
                  Stockholder's employment with the LLC

                  was terminated by the LLC other than For Cause or
                  Unsatisfactory Performance, then the Repurchase Price shall
                  equal (which is intended to be a proxy for market value):

                           (A) seven (7.0) multiplied by the positive
                           difference, if any (the "Applicable Cash Flow"), of
                           (x) the sum of (I) fifty percent (50%) of the LLC's
                           Maintenance Fees for the twenty-four (24) months
                           ending on the last day of the calendar quarter in
                           which the termination of such Employee Stockholder's
                           employment occurs and (II) thirty three and thirty
                           three one hundredths percent (33.33%) of the LLC's
                           Earned Performance Fees for the thirty-six (36)
                           months ending on the last day of the calendar quarter
                           in which the termination of such Employee
                           Stockholder's employment occurs minus (y) the amount
                           by which the actual expenses of the LLC (determined
                           on an accrual basis in accordance with generally
                           accepted accounting principles consistently applied)
                           exceeded the Operating Allocation of the LLC
                           (including previously reserved Operating Allocation)
                           during the twelve (12) months ending the last day of
                           the calendar quarter in which the termination of such
                           Employee Stockholder's employment occurs, multiplied
                           by

                           (B) a fraction (the "Applicable Fraction"), the
                           numerator of which is the number of Vested LLC Points
                           being purchased in the Repurchase, and the
                           denominator of which is the number of LLC Points
                           outstanding on the date of the closing of the
                           Repurchase (before giving effect to any issuance,
                           redemption or vesting of LLC Points on such date).

                           (ii)In all other cases, (including, without
                  limitation, the quitting or resignation of an Employee
                  Stockholder or the termination of such Employee Stockholder
                  For Cause or for Unsatisfactory Performance), the Repurchase
                  Price shall equal (A) three (3.0) multiplied by (B) the
                  Applicable Cash Flow multiplied by (C) the Applicable
                  Fraction; PROVIDED, HOWEVER, that for any Repurchase under
                  this clause (ii) relating to such a termination of employment
                  occurring within (I) the first five (5) years after the
                  Effective Date, with respect to Initial LLC Points, or (II)
                  the first five (5) years (or any such shorter period as may be
                  expressly provided in the Purchase Program or agreements
                  entered into thereunder with respect to particular LLC Points)
                  after the date of receipt by the Employee Stockholder, with
                  respect to any other LLC Points held by such Employee
                  Stockholder, the Repurchase Price shall be $1.00. Sample
                  calculations under Section 3.11(c)(i) and Section 3.11(c)(ii)
                  are attached as SCHEDULE B hereto.

         If a Repurchase Price must be determined prior to (A) twenty-four (24)
months after the Effective Date, then the amount of the LLC's Maintenance Fees
for the portion of the relevant twenty-four (24) month period before the
Effective Date shall be calculated on a pro-forma basis such that the
Maintenance Fees of the LLC for the relevant period prior to the Effective Date
shall be deemed to be equal to fifty percent (50%) of the Revenues From
Operations of the LLC's predecessor, Edward C. Rorer & Co., Inc., for such
period multiplied by the lesser of (x) one (1) or 



                                       29

(y) a fraction, the numerator of which is the sum of the Contract Values of each
Advisory Contract (which was not terminated at or prior to the Closing or the
Asset Transfer and was assigned to the LLC and with respect to which the Client
of the LLC gave its Consent to the assignment resulting from the transactions
contemplated by the Stock Purchase Agreement), and the denominator of which
shall be the Base Fees, and (B) thirty-six (36) months after the Effective Date,
then the amount of the LLC's Earned Performance Fees for the portion of the
relevant thirty-six (36) month period before the Effective Date shall be deemed
zero. Capitalized terms used in this paragraph and not otherwise defined herein
shall have the meaning ascribed to such terms in Section 9.3 of the Stock
Purchase Agreement.

                  (d) The rights of AMG, the Manager Member, the LLC and their
assignees hereunder are in addition to and shall not affect any other rights
which AMG, the Manager Member, the LLC or their assigns may otherwise have to
repurchase LLC Interests (including, without limitation, pursuant to any
agreement entered into by a Non-Manager Member or an Additional Non-Manager
Member which provides for the vesting of LLC Points).

                  (e) On the Repurchase Closing Date, AMG and/or the LLC or 
their respective assignees (as applicable) shall pay to the Repurchased 
Member the Repurchase Price for the LLC Interests repurchased in the manner 
set forth in this Section 3.11, and upon such payment the Repurchased Member 
shall cease to hold any LLC Interests, and such Repurchased Member 
automatically shall be deemed to have withdrawn from the LLC and shall cease 
to be a Member of the LLC and shall no longer have any rights hereunder; 
PROVIDED, HOWEVER, that the provisions of this Article III shall continue as 
set forth in Section 3.11(f) below. On the Repurchase Closing Date, the 
Repurchased Member and the LLC (and if AMG is purchasing LLC Interests from 
the Repurchased Member, AMG) (or their assignees) shall, if AMG so requests, 
execute an agreement reasonably acceptable to the Manager Member (i) in which 
the Repurchased Member represents and warrants to the Manager Member and/or 
AMG and/or the LLC, as applicable (or their assignees), that it has sole 
record and beneficial title to the Repurchased Interest, free and clear of 
any Liens other than those imposed by this Agreement and (ii) addressing such 
other matters as AMG reasonably requests. Payment of the Repurchase Price 
shall be made as follows: (A) in the case of termination of employment 
because of death or Permanent Incapacity (to the extent of the collected 
proceeds of any disability insurance policies under which the LLC is the 
beneficiary upon the permanent incapacity of such Employee Stockholder, net 
of any tax liability expected to result to the LLC and/or the other Members 
therefrom), by wire-transfer of immediately available funds on the Repurchase 
Closing Date to an account designated by the Repurchased Member at least 
three (3) business days prior to the Repurchase Closing Date, and (B) in the 
case of any other termination of employment (including a termination of 
employment because of Permanent Incapacity to the extent the obligation 
exceeds the proceeds of any key-man disability insurance policies described 
above (net of any tax liability expected to result to the LLC and/or the 
other Members therefrom)), (I) in the case of a termination by the LLC other 
than For Cause or Unsatisfactory Performance, on the Repurchase Closing Date; 
and (II) in the case of any other termination, on the later to occur of (x) 
the Repurchase Closing Date or (y) the date which is the first business day 
after the fifth anniversary of the Effective Date.

                  (f) If an Employee Stockholder's employment with the LLC is 
terminated because such Employee Stockholder has quit or resigned (other than 
a resignation which is included in the definition of "Retirement") or was 
terminated For Cause or for Unsatisfactory Performance, 

                                       30
<PAGE>

then, at the sole discretion of the Manager Member, the payment required by this
Section 3.11 may be made with a promissory note in the form attached hereto as
EXHIBIT C, with an initial principal amount equal to the Repurchase Price, and
the principal of which promissory note would be paid in four (4) equal annual
installments, with the first installment to be paid on the date payment of the
Repurchase Price would be required under Section 3.11(e) above (in each case,
subject to the terms and conditions of this Agreement and such note).

                  (g) AMG may assign and/or delegate any or all of its rights 
and obligations under this Section 3.11, in one or more instances, to the 
Manager Member or to any other Person; PROVIDED, HOWEVER, that no such 
assignment or delegation shall relieve AMG of its obligation to make payment 
of a Repurchase Price. AMG may, with a Majority Vote (excluding, for purposes 
of determining such Majority Vote, the Non-Manager Member whose interest is 
being repurchased), assign any or all of its rights and obligations under 
this Section 3.11, in one or more instances, to the LLC, provided that the 
foregoing limitation shall have no effect on the LLC's obligation set forth 
in Section 3.11(a)(i) regarding the use of the proceeds of a key-man life or 
disability insurance policy.

                  (h) In the event that a Non-Manager Member or Employee
Stockholder (or other holder of LLC Points, other than the Manager Member) (i)
has filed a voluntary petition under the bankruptcy laws or a petition for the
appointment of a receiver or makes any assignment for the benefit of creditors,
(ii) is subject involuntarily to such a petition or assignment or to an
attachment or other legal or equitable interest with respect to any of its LLC
Interests or, in the case of an Employee Stockholder which is not a Non-Manager
Member, its interests in the Non-Manager Member which it owns, and such
involuntary petition or assignment or attachment is not discharged within sixty
(60) days after its effective date, or (iii) is subject to a Transfer of any of
its LLC Interests or, in the case of an Employee Stockholder which is not a
Non-Manager Member, its interests in the Non-Manager Member which it owns, by
court order or decree or by operation of law, then AMG shall in its sole
discretion be entitled to purchase all the LLC Interests held by such
Non-Manager Member (or other holder of LLC Points, other than the Manager
Member) (including the Non-Manager Member through which such Employee
Stockholder holds his or her interest in the LLC) pursuant to the terms of this
Section 3.11 as if such Non-Manager Member (or other holder of LLC Points) was a
Repurchased Member with the purchase price determined pursuant to Section
3.11(c)(ii) and the date of the closing to be determined by the Manager Member
in its discretion. In order to give effect to clause (iii) of the foregoing, if
any of the interests of a Non-Manager Member in the LLC, or of an Employee
Stockholder in a Non-Manager Member, become subject to Transfer (or purport to
be or have been Transferred) by a court order or decree or by operation of law,
the Non-Manager Member (or other holder of LLC Points, other than the Manager
Member) (whose interest in the LLC or the interests in which are subject to such
Transfer) shall cease to be a Member of the LLC, and the transferee by court
order or decree or by operation of law shall not become a Member, and AMG shall
have the right in its sole discretion to purchase from the Non-Manager Member
which has ceased to be a Non-Manager Member (or other holder of LLC Points), all
his, her or its interest in the LLC as set forth in the preceding sentence. In
the event that AMG in its sole discretion determines not to purchase the LLC
Interests held by a Non-Manager Member (or other holder of LLC Points, other
than the Manager Member) pursuant to the foregoing provisions of this Section
3.11(h), AMG shall assign its right to make such purchase to any one or more
other Non-Manager Members who desire to make such purchase for their own
accounts, and who the Management Committee shall have authorized in writing to
make such purchase (the 



                                       31
<PAGE>

Management Committee determining the respective percentages such other
Non-Manager Members shall be permitted to purchase), and such other Non-Manager
Member(s) shall be entitled to purchase such LLC Interests on the same terms
that would have been applicable to AMG had it elected to make such purchase
pursuant to the foregoing provisions of this Section 3.11(h).

                  (i) In the event that a Non-Manager Member is required to 
sell its LLC Interests pursuant to the provisions of this Section 3.11, and 
in the further event that such Non-Manager Member refuses to, is unable to, 
or for any reason fails to, execute and deliver the agreements required by 
this Section 3.11, the LLC or AMG, as applicable (or their respective assigns 
or designees, as applicable) may deposit the purchase price, if any, therefor 
(including cash and/or promissory notes) with any bank doing business within 
fifty (50) miles of the LLC's principal place of business, or with the LLC's 
accounting firm, as agent or trustee, or in escrow, for the Non-Manager 
Member, to be held by such bank or accounting firm for the benefit of and for 
delivery to such Non-Manager Member. Upon such deposit by the LLC or AMG (or 
their respective assigns) and upon notice thereof given to the Non-Manager 
Member (or other holder of LLC Points, other than the Manager Member), such 
Non-Manager Member's LLC Interests automatically shall be deemed to have been 
sold, transferred, conveyed and assigned to the LLC or AMG (or their 
assigns), as applicable, the Non-Manager Member shall cease to hold any LLC 
Interests, shall cease to be a Member of the LLC and shall have no further 
rights with respect thereto (other than the right to withdraw the payment 
therefor, if any, held in escrow), and the Manager Member shall record such 
transfer or repurchase on SCHEDULE A hereto.

         SECTION 3.12 NO EMPLOYMENT OBLIGATION. Each Non-Manager Member and each
Employee Stockholder acknowledges that neither this Agreement nor the provisions
of the Non-Solicitation Agreement creates an obligation on the part of the LLC
to continue the employment of an Employee Stockholder or any other Person with
the LLC, and that such Employee Stockholder, unless he or she is a party to an
Employment Agreement, is an employee at will of the LLC.

         SECTION 3.13 CAPITALIZATION OF EXCESS OPERATING CASH FLOW. At any time
the Management Committee reasonably believes that the Operating Allocation of
the LLC will exceed the actual expenses of the LLC (taking into account business
conditions at the time and including both a reasonable allowance for either loss
of business or a change in margins in the business), at the request of the
Management Committee, representatives of the Manager Member shall meet with the
Management Committee to discuss the extent of such excess and the Management
Committee and the Manager Member shall reasonably and in good faith agree upon
the amount (if any) of such excess. Upon such agreement, the Management
Committee and the Manager Member shall negotiate in good faith for the purpose
of determining a reasonable and appropriate means to permit the Non-Manager
Members to utilize such excess Operating Allocation. Subject to such agreement,
such means may include (but shall not be limited to) the following examples: An
increase in the percentage of Revenues from Operations that constitutes Owners'
Allocation (together with the grant of put rights applicable to such adjusted
Owners' Allocation on terms comparable to those set forth in Article VII
hereof), the purchase of all or a portion of any excess by AMG or the Manager
Member (or its designee(s)) on terms comparable to the terms set forth in
Article VII hereof with respect to Puts or Section 3.11 with respect to
Repurchases or any combination of the foregoing.

         SECTION 3.14 MISCELLANEOUS. Each Member and each Employee Stockholder
agrees that the enforcement of the provisions of Sections 3.8, 3.9, 3.10 and
3.11 hereof, and the enforcement of the provisions of the Employment Agreements
and Non-Solicitation Agreements are necessary to ensure the protection and
continuity of the business, goodwill and confidential business information of
the LLC for the benefit of each of the Members. Each Member and each Employee
Stockholder agrees that, due to the proprietary nature of the LLC's business,
the restrictions set forth in Section 3.9 hereof and in the Employment
Agreements and the Non-Solicitation Agreements are reasonable as to duration and
scope. If any provision contained in this Article III shall for any reason be
held invalid, illegal or unenforceable in any respect, such invalidity,
illegality or unenforceability shall not affect any other provision of this
Article III. It is the intention of the parties hereto that if any of the
restrictions or covenants contained herein is held to cover a geographic area or
to be for a length of time that is not permitted by applicable law, or is any
way construed to be too broad or to any extent invalid, such provision shall not
be construed to be null, void and of no effect, but to the extent such provision
would then be valid or enforceable under applicable law, such provision shall be
construed and interpreted or reformed to provide for a restriction or covenant
having the maximum enforceable geographic area, time period and other provisions
as shall be valid and enforceable under applicable law.

         Each Member and Employee Stockholder acknowledges that the obligations
and rights under Sections 3.8, 3.9, 3.10 and 3.11 and this Section 3.14 shall
survive the termination of the employment of an Employee Stockholder with the
LLC and/or the withdrawal or removal of a Member from the LLC, regardless of the
manner of such termination, withdrawal or removal in accordance with the
provisions hereof and of the relevant Employment or Non-Solicitation Agreement.
Moreover, each Member agrees that the remedies provided herein, are reasonably
related to the anticipated loss that the LLC and the Members (including, without
limitation, the Manager Member which would be purchasing LLC Interests from a
Non-Manager Member) would suffer upon a breach of such provisions. Except as
agreed to by the Manager Member, in advance in a writing making specific
reference to this Article III, no Employee Stockholder or Non-Manager Member
shall enter into any agreement or arrangement which is inconsistent with the
terms and provisions hereof.


                      ARTICLE IV - CAPITAL CONTRIBUTIONS;
                CAPITAL ACCOUNTS AND ALLOCATIONS; DISTRIBUTIONS.

         SECTION 4.1CAPITAL CONTRIBUTIONS.

                  (a) On or prior to the Effective Date, Edward C. Rorer & 
Co., Inc. contributed to the LLC certain of its assets, properties, rights, 
powers, privileges and business (and the goodwill associated therewith) and 
the LLC assumed all of the liabilities of Edward C. Rorer & Co., Inc., and 
the Members agree that such Capital Contribution had the value set forth on 
Schedule A hereto. Except as may be agreed to in connection with the issuance 
of additional LLC Points, as specifically set forth herein, or as may be 
required under applicable law, the Members shall not be required to make any 
further capital contributions to the LLC. No Member shall make any capital 
contribution to the LLC without the prior consent of the Manager Member.

                                       33
<PAGE>

                  (b)No Member shall have the right to withdraw any part of his,
her or its (or their predecessors in interest) Capital Contribution until the
dissolution and winding up of the LLC, except as distributions pursuant to this
Article IV may represent returns of capital, in whole or in part. No Member
shall be entitled to receive any interest on any Capital Contribution made by it
(or its predecessors in interest) to the LLC. No Member shall have any personal
liability for the repayment of any Capital Contribution of any other Member.

         SECTION 4.2 CAPITAL ACCOUNTS; ALLOCATIONS.

                  (a) There shall be established for each Member a Capital 
Account (a "Capital Account") which, in the case of each Member, shall 
initially be equal to the Capital Contribution of such Member as set forth on 
SCHEDULE A hereto.

(b)The Capital Account of each Member shall be adjusted in the following manner.
Each Capital Account shall be increased by such Member's allocable share of
income and gain, if any, of the LLC (as well as the Capital Contributions made
by a Member after the Effective Date) and shall be decreased by such Member's
allocable share of deductions and losses, if any, of the LLC and by the amount
of all distributions made to such Member. The amount of any distribution of
assets other than cash shall be deemed to be the Fair Market Value of such
assets (net of any liabilities encumbering such property that the distributee
Member is considered to assume or take subject to). Capital Accounts shall also
be adjusted upon the issuance of additional LLC Interests as set forth in
Section 5.5(c) and upon the transfer of LLC Interests as set forth in Section
5.1. To the extent not otherwise provided for in this Agreement, the Capital
Accounts of the Members shall be adjusted and maintained in accordance with the
rules of Treasury Regulations Section 1.704-1(b)(2)(iv), as the same may be
amended or revised. Any references in any section of this Agreement to the
Capital Account of a Member shall be deemed to refer to such Capital Account as
the same may be credited or debited from time to time as set forth above.

                  (c) Subject to Sections 4.2(e), 4.2(g) and 4.5 hereof, all 
items of LLC income and gain shall be allocated among the Members' Capital 
Accounts at the end of every calendar quarter as follows:

                          (i) first, items of income and gain shall be allocated
                  to the Manager Member in an amount equal to the Owners'
                  Allocation for such calendar quarter (net of Owners'
                  Allocation Expenditures for such calendar quarter) multiplied
                  by a fraction (1) the numerator of which is the sum of the
                  number of LLC Points held by the Manager Member as of the
                  first day of such calendar quarter and (2) the denominator of
                  which is the number of LLC Points outstanding as of the first
                  day of such calendar quarter, provided, that for the first
                  full calendar quarter following the Effective Date, the
                  Manager Member shall be allocated additional items of income
                  and gain totaling $112,000 pursuant to this clause (i);

                          (ii) second, the Manager Member shall be allocated
                  items of income and gain until the Manager Member has been
                  allocated cumulative income and gain under this Section
                  4.2(c)(ii) equal to the cumulative amount of losses and
                  deductions allocated to the Manager Member under Sections
                  4.2(d)(ii) and 4.2(d)(iii) in prior periods if any;



                                       34
<PAGE>

                          (iii) third, items of income and gain, if any, shall
                  be allocated (A) first, to each Non-Manager Member in an
                  amount equal to the Owners' Allocation for such calendar
                  quarter (net of Owners' Allocation Expenditures for such
                  calendar quarter) multiplied by a fraction (1) the numerator
                  of which is the sum of the number of Vested LLC Points held by
                  such Non-Manager Member as of the first day of such calendar
                  quarter and (2) the denominator of which is the number of LLC
                  Points outstanding as of the first day of such calendar
                  quarter, and (B) second, to Edward C. Rorer if he was a
                  Non-Manager Member as of the first day of such calendar
                  quarter, and otherwise among all Non-Manager Members in
                  accordance with (and in proportion to) each Non-Manager
                  Member's respective number of Vested LLC Points on the first
                  day of such calendar quarter, in an amount equal to the
                  remaining Owners' Allocation for such calendar quarter (net of
                  Owners' Allocation Expenditures for such calendar quarter),
                  until the aggregate amount of such items allocated to the
                  Members (including both the Manager Member and the Non-Manager
                  Members) pursuant to Sections 4.2(c)(i) and 4.2(c)(ii) and
                  this 4.2(c)(iii) for such calendar quarter equal the aggregate
                  amount of the Owners' Allocation (net of Owners' Allocation
                  Expenditures) for such calendar quarter, provided, that for
                  the first full calendar quarter following the Effective Date,
                  the aggregate items of income and gain allocated to the
                  Non-Manager Members pursuant to this clause (iii) shall be
                  reduced by $112,000 (such reduction to be borne pro rata by
                  the Non-Manager Members in accordance with the proportions of
                  income and gain allocated to the Non-Manager Members pursuant
                  to this clause (iii) for such calendar quarter);

                          (iv) finally, all remaining items of LLC income and
                  gain shall be allocated among the Non-Manager Members in
                  accordance with (and in proportion to) each Non-Manager
                  Member's respective number of Vested LLC Points on the first
                  day of such calendar quarter.

                  (d) Except to the extent provided in Sections 4.2(f), 
4.2(g) and 4.5, all items of LLC loss and deduction shall be allocated among 
the Members' Capital Accounts at the end of every calendar quarter as follows:

                           (i) first, all items of LLC loss and deduction for
                  such calendar quarter shall be allocated (A) first, among the
                  Non-Manager Members in accordance with (and in proportion to)
                  each Non-Manager Member's respective number of Vested LLC
                  Points on the first day of such calendar quarter, until 
                  the aggregate allocations to the Non-Manager Members pursuant
                  to this clause (A) equals the aggregate amount of allocations
                  of income and gain to the Non-Manager Members pursuant to 
                  Section 4.2(c)(iv) for such calendar quarter, (B) second, 
                  to Edward C. Rorer if he was a Non-Manager Member as of the 
                  first day of such calendar quarter, and otherwise among all 
                  Non-Manager Members in accordance with (and in proportion to)
                  each Non-Manager Member's respective number of Vested LLC 
                  Points on the first day of such calendar quarter, until the 
                  aggregate allocations to such Person(s) pursuant to this 
                  clause (B) equals the aggregate amount of allocations of 
                  income and gain to such Person(s) pursuant to Section 
                  4.2(c)(iii)(B) for such

                  calendar quarter, and (C) third, among the Non-Manager Members
                  in accordance with (and in proportion to) their respective
                  numbers of Vested LLC Points on the first day of such calendar
                  quarter, until all such Capital Accounts shall have been
                  reduced to zero (0) (after giving effect to the allocations of
                  income and gain for such calendar quarter under Section
                  4.2(c)), provided that no additional loss or deduction shall
                  be allocated to any Non-Manager's Capital Account pursuant to
                  this Section 4.2(d)(i) once such Capital Account has been
                  reduced to zero (0) (but losses and deductions shall continue
                  to be allocated to the Capital Accounts of the other
                  Non-Manager Members pursuant to this Section 4.2(d)(i) until
                  all such Non-Manager Members' Capital Accounts have been
                  reduced to zero (0));

                          (ii) second, all items of LLC loss and deduction for
                  such calendar quarter not allocated to the Non-Manager Members
                  under Section 4.2(d)(i) shall be allocated to the Manager
                  Member until its Capital Account shall have been reduced to
                  zero (0); and

                          (iii) finally, all items of LLC loss and deduction for
                  such calendar quarter not allocated to the Members under
                  Sections 4.2(d)(i) and 4.2(d)(ii) shall be allocated among all
                  Members in accordance with (and in proportion to) each
                  Member's respective number of LLC Points as of the first day
                  of such calendar quarter.

                  (e) If the LLC has a net gain from any sale, exchange or
disposition of all, or substantially all, of the assets of the LLC, then that
net gain shall be allocated among the Members as follows:

                           (i) first, gain shall be allocated to the Manager
                  Member until the Manager Member has been allocated cumulative
                  gain which, together with income and gain previously allocated
                  to the Manager Member under Section 4.2(c)(ii) hereof, equals
                  the cumulative amount of losses and deductions allocated to
                  the Manager Member under Sections 4.2(d)(ii) and 4.2(d)(iii)
                  in prior periods;

                           (ii) thereafter, gain shall be allocated among the
                  Members in accordance with (and in proportion to) their
                  respective number of Vested LLC Points as of the date of the
                  transaction.

                  (f) If the LLC has a net loss from any sale, exchange or 
other disposition of all, or substantially all, of the assets of the LLC, 
then that net loss shall be allocated among the Members in accordance with 
(and in proportion to) their respective number of Vested LLC Points as of the 
date of the transaction, provided that no additional losses shall be 
allocated to a Member once its Capital Account has been reduced to zero (0), 
unless all Members' Capital Accounts have then been reduced to zero (0). All 
items of LLC deduction relating to the payment by the LLC of a Royalty (as 
defined therein) ("Royalty") for a calendar quarter pursuant to the License 
Agreement shall be allocated at the end of such calendar quarter solely to 
the Manager Member.

                  (g) In the event that during any calendar quarter (or any
fiscal year) there is any change of Members or LLC Points (whether as a result
of the admission of an Additional Non-Manager Member, the redemption by the LLC
of all (or any portion of) any Non-Manager Member's LLC Points, an issuance or
transfer of any LLC Points or otherwise), the following shall apply: (i) such
transfer shall be deemed to have occurred as of the end of the last day of the
calendar 



                                       36
<PAGE>

quarter in which such change occurred, (ii) the books of account of the LLC
shall be closed effective as of the close of business on the effective date of
any such change as set forth in clause (i) and such fiscal year shall thereupon
be divided into two or more portions, (iii) each item of income, gain, loss and
deduction shall be determined (on the closing of the books basis) for the
portion of such fiscal year ending with the date on which the books of account
of the LLC are so closed, and (iv) each such item for such portion of such
fiscal year shall be allocated (pursuant to the provisions of Sections 4.2(c)
and (d) hereof) to those Persons who were Members during such portion of such
fiscal year in accordance with their respective LLC Points during such period.



         SECTION 4.3DISTRIBUTIONS.

                  (a)Subject to Section 4.4 hereof, from and after the date
hereof, within thirty (30) days after the end of each calendar quarter, the
Manager Member shall, to the extent cash is available therefor, and based on the
unaudited financial statements for such calendar quarter prepared in accordance
with Section 9.3 hereof (after approval thereof by the Manager Member), cause
the LLC to (i) first, distribute to the Manager Member an amount equal to the
allocations of income and gain to the Manager Member pursuant to Section
4.2(c)(i) and/or Section 4.2(c)(ii) for such calendar quarter (less the Manager
Member's pro rata portion of any reservation from the Owners' Allocation
pursuant to the last sentence of this Section 4.3(a)), and less an amount equal
to the Royalty payments made by the LLC pursuant to the License Agreement for
such calendar quarter), (ii) second, distribute to each Non-Manager Member (and
each Person who was a Non-Manager Member at any time during such calendar
quarter) an amount equal to the allocation of income and gain to such
Non-Manager Member pursuant to Section 4.2(c)(iii)(A) for such calendar quarter,
less an amount equal to the allocation of losses and deductions to such
Non-Manager Member pursuant to Section 4.2(d)(i)(C) for such calendar quarter
(and less each such Person's pro rata portion of any reservation from the
Owners' Allocation pursuant to the last sentence of this Section 4.3(a)), and
(iii) third, distribute to each Non-Manager Member (and each Person who was a
Non-Manager Member at any time during such calendar quarter) an amount equal to
the allocation of income and gain to such Non-Manager Member pursuant to Section
4.2(c)(iii)(B) for such calendar quarter, less an amount equal to the allocation
of losses and deductions to such Non-Manager Member pursuant to Section
4.2(d)(i)(B) for such calendar quarter (and less each such Person's pro rata
portion of any reservation from the Owners' Allocation pursuant to the last
sentence of this Section 4.3(a)). Within sixty (60) days after the end of each
fiscal year of the LLC, the Manager Member shall, based on the audited financial
statements prepared in accordance with Section 9.3 hereof, cause the LLC to make
a distribution, of the remaining Owners' Allocation, if any, for the preceding
fiscal year which was allocated pursuant to Sections 4.2(c)(i), 4.2(c)(ii) and
4.2(c)(iii) but not previously distributed, in accordance with the foregoing
clauses (i), (ii) and (iii) of this Section 4.3(a) whenever, and to the extent,
cash is available therefor. Notwithstanding the foregoing, the Manager Member
may, with a Majority Vote, from time to time, reserve and not distribute
portions of the Owners' Allocation for LLC purposes, including, without
limitation, to increase the net worth of the LLC, to make capital expenditures
(such as the creation of or investment in a Controlled Affiliate) or to create a
reserve for anticipated repurchases of LLC Interests, provided that any such
reservation shall be made from all Members pro-rata in proportion to LLC Points.

<PAGE>

                  (b)Except as otherwise set forth herein, all other amounts or
proceeds available for distribution, if any, shall be distributed to the Members
at such time as may be determined by the Manager Member, provided that any such
distribution shall be made among the Members (i) in accordance with (and in
proportion to) the positive balances (if any) in their respective Capital
Accounts (as determined immediately prior to such distribution) until all such
positive Capital Account balances have been reduced to zero, and (ii) thereafter
among all Members in accordance with (and in proportion to) their respective
numbers of LLC Points at the time of such distribution (PROVIDED, HOWEVER, that
if a Member makes a Capital Contribution after the Effective Date, the Manager
Member may cause the LLC to make a priority return of such Capital Contribution.

                  (c)Notwithstanding any other provision of this Agreement,
neither the LLC, nor the Manager Member on behalf of the LLC, shall make a
distribution to any Member on account of its LLC Interest if such distribution
would violate the Act or other applicable law.

         SECTION 4.4 DISTRIBUTIONS UPON DISSOLUTION; ESTABLISHMENT OF A RESERVE
UPON DISSOLUTION. Upon the dissolution of the LLC, the assets of the LLC shall
first go toward the payment (or the making of reasonable provision for the
payment) of all liabilities of the LLC owing to creditors, including the setting
up of such reserves by the Manager Member, or if there is none, the Liquidating
Trustee appointed as set forth in Section 8.4 hereof, as it deems reasonably
necessary for any liabilities or other obligations of the LLC. Such reserves may
be paid over by the Manager Member or Liquidating Trustee to a bank (or other
third party), to be held in escrow for the purpose of paying any such
liabilities or other obligations. At the expiration of such period(s) as the
Manager Member or Liquidating Trustee may deem advisable, such reserves, if any
(and any other assets available for distribution), or a portion thereof, shall
be distributed to the Members (i) in accordance with (and in proportion to) the
positive balance (if any) in their respective Capital Accounts (as determined
immediately prior to each such distribution) until all such positive Capital
Account balances have been reduced to zero, and (ii) thereafter, among the
Members as of the date of dissolution in accordance with their respective
numbers of LLC Points as of the date of dissolution. If any assets of the LLC
are to be distributed in kind in connection with such liquidation, such assets
shall be distributed on the basis of their Fair Market Value net of any
liabilities encumbering such assets and, to the greatest extent possible, shall
be distributed pro-rata in accordance with the total amounts to be distributed
to each Member. In the event that a distribution referenced in the immediately
preceding sentence cannot be distributed pro-rata, the Members understand and
acknowledge that a Member may be compelled to accept a distribution of any asset
in kind from the LLC despite the fact that the percentage of the asset
distributed to such Member exceeds the percentage of that asset which is equal
to the percentage in which such Member shares in distributions from the LLC.
Immediately prior to the effectiveness of any such distribution-in-kind, each
item of gain and loss that would have been recognized by the LLC had the
property being distributed been sold at Fair Market Value shall be determined
and allocated to those Persons who were Members immediately prior to the
effectiveness of such distribution in accordance with Section 4.2(d).

         SECTION 4.5 PROCEEDS FROM CAPITAL CONTRIBUTIONS AND THE SALE OF
SECURITIES; INSURANCE PROCEEDS; CERTAIN SPECIAL ALLOCATIONS.



                                       38
<PAGE>

                  (a) MINIMUM GAIN CHARGEBACK. Notwithstanding any other
provision in this Article IV, if there is a net decrease in Partnership Minimum
Gain or Partner Nonrecourse Debt Minimum Gain (determined in accordance with the
principles of Treasury Regulations Sections 1.704-2(d) and 1.704-2(i)) during
any taxable year, the Members shall be specially allocated items of LLC income
and gain for such year (and, if necessary, subsequent years) in an amount equal
to their respective shares of such net decrease during such year, determined
pursuant to Treasury Regulations Sections 1.704-2(g) and 1.704-2(i)(5). The
items to be so allocated shall be determined in accordance with Treasury
Regulations Section 1.704-2(f). This Section 4.5(a) is intended to comply with
the minimum gain chargeback requirements in such Treasury Regulations Sections
and shall be interpreted consistently therewith; including that no chargeback
shall be required to the extent of the exceptions provided in Treasury
Regulations Sections 1.704-2(f) and 1.704-2(i)(4).

                  (b) QUALIFIED INCOME OFFSET. In the event any Member
unexpectedly receives any adjustments, allocations, or distributions described
in Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of
LLC income and gain shall be specially allocated to such Member in an amount and
manner sufficient to eliminate the deficit balance in his Capital Account
created by such adjustments, allocations or distributions as promptly as
possible.

                  (c) GROSS INCOME ALLOCATION. In the event any Member has a
deficit Capital Account at the end of any fiscal year which is in excess of the
sum of (i) the amount such Member is obligated to restore, if any, pursuant to
any provision of this Agreement, and (ii) the amount such Member is deemed to be
obligated to restore pursuant to the penultimate sentences of Treasury
Regulations Section 1.704-2(g)(1) and 1.704-2(i)(5), each such Member shall be
specially allocated items of LLC income and gain in the amount of such excess as
quickly as possible, provided that an allocation pursuant to this Section 4.5(c)
shall be made only if and to the extent that a Member would have a deficit
Capital Account in excess of such sum after all other allocations provided for
in this Article IV have been tentatively made as if Section 4.5(b) and this
Section 4.5(c) were not in this Agreement.

                  (d) NONRECOURSE DEDUCTIONS. Nonrecourse Deductions shall be
allocated among the Members in accordance with their respective numbers of LLC
Points.

                  (e) PARTNER NONRECOURSE DEDUCTIONS. Partner Nonrecourse
Deductions for any taxable period shall be allocated to the Member who bears the
economic risk of loss with respect to the liability to which such Partner
Nonrecourse Deductions are attributable in accordance with Treasury Regulations
Section 1.704-2(j).

                  (f) CURATIVE ALLOCATIONS. The allocations set forth in
Sections 4.5(a), (b), (c), (d), and (e) hereof (the "Regulatory Allocations")
are intended to comply with certain requirements of the Treasury Regulations. It
is the intent of the Members that, to the extent possible, all Regulatory
Allocations shall be offset either with other Regulatory Allocations or with
special allocations of other items of LLC income, gain, loss or deduction
pursuant to this Section 4.5(f), and to the extent Regulatory Allocations are
necessary, it is the intent of the Members that they be made in as consistent a
manner with the provisions of Section 4.2 hereof as practicable, subject to
compliance with the Treasury Regulations. Therefore, notwithstanding any other
provision of this Article IV (other than the Regulatory Allocations), the
Manager Member shall make such offsetting special allocations of LLC income,
gain, loss or deduction in whatever manner it determines appropriate so 



                                       39
<PAGE>

that, after such offsetting allocations are made, each Member's Capital Account
is, to the extent possible, equal to the Capital Account balance such Member
would have had if the Regulatory Allocations were not a part of this Agreement
and all LLC items were allocated pursuant to Section 4.2. In exercising its
discretion under this Section 4.5(f), the Manager Member shall take into account
future Regulatory Allocations under Section 4.5(a) that, although not yet made,
are likely to offset other Regulatory Allocations previously made under Sections
4.5(d) and (e).

                  (g) Capital Contributions made by any Member after the
Effective Date, and other proceeds from the issuance of securities by the LLC
may, in the sole discretion of the Manager Member, be used for the benefit of
the LLC (including, without limitation, the repurchase or redemption of LLC
Interests), or, may be distributed by the LLC, in which case, any such proceeds
shall be allocated and distributed among the Members in accordance with their
respective LLC Points immediately prior to the date of such contribution or
issuance of securities; it being understood that in the case the proceeds are a
note receivable, any such distribution shall only occur, if at all, upon receipt
by the LLC of any cash in respect thereof.

                  (h) In the event of the death or Permanent Incapacity of an
Employee Stockholder covered by key-man life or disability insurance, as
applicable, the premiums on which have been paid by the LLC, the proceeds of any
such policy (net of any expected tax liability to be incurred by the LLC and/or
any Member as a result of the receipt by the LLC of such proceeds) shall first
be used by the LLC to fund (to the extent thereof) the Repurchase of LLC
Interests from the Employee Stockholder or Non-Manager Member through which such
Employee Stockholder holds or held his or her interest in the LLC in accordance
with Section 3.11 hereof and, if the after-tax proceeds exceed the amounts so
required to effect such Repurchase, then the amount of such excess proceeds may,
in the sole discretion of the Manager Member, be used for the benefit of the
LLC, or, may be distributed by the LLC, in which case, any such proceeds shall
be allocated and distributed among the Members in accordance with their
respective LLC Points immediately following the Repurchase of the LLC Interests
from such Non-Manager Member. Notwithstanding any other provision of this
Agreement to the contrary, in the event the LLC receives proceeds from any
insurance policy owned or otherwise maintained by or benefitting the LLC and the
receipt of such proceeds is for any reason expected to result in a tax liability
to one or more of the Members, the Manager Member may, in its sole discretion,
distribute that portion of such insurance proceeds to such Member(s) as is
necessary to partially or fully (in the Manager Member's sole discretion)
reimburse such Member(s) for the actual tax liabilities incurred by such
Member(s) as a result of the LLC's receipt of such proceeds and the receipt by
such Member of a distribution pursuant to this sentence, provided that, in the
event the Manager Member determines to make any distributions of proceeds
pursuant to this sentence, each Member incurring tax liabilities as a result of
the LLC's receipt of such insurance proceeds shall be reimbursed in the same
proportion (as compared to the total tax liability it incurs) as each other
Member receiving reimbursement pursuant to this sentence, and provided, further,
that any Member receiving reimbursement pursuant to this sentence shall promptly
reimburse to the LLC any portion of such reimbursement that exceeds the actual
tax liabilities resulting to such Member as a result of the LLC's receipt of
such insurance proceeds and the receipt by such Member of a distribution
pursuant to this sentence.

                  (i) All items of depreciation or amortization (as calculated
for book purposes in accordance with generally accepted accounting principles,
consistently applied) on account of the intangible items of property of the LLC
on the Effective Date shall be specially allocated to the 



                                       40
<PAGE>

Manager Member, and all items of depreciation or amortization (as calculated for
book purposes in accordance with generally accepted accounting principles,
consistently applied) on account of the tangible items of property of the LLC on
the Effective Date shall be specially allocated to the Non-Manager Members as
set forth in Section 4.2(d)(i). All items of depreciation or amortization (as
calculated for book purposes in accordance with generally accepted accounting
principles, consistently applied) on account of property (whether tangible or
intangible) purchased out of the Operating Allocation shall be allocated as set
forth in Section 4.2(d)(i), and all items of depreciation or amortization (as
calculated for book purposes in accordance with generally accepted accounting
principles, consistently applied) on account of property (whether tangible or
intangible) purchased out of the Owners' Allocation shall be allocated among the
Members in accordance with their respective numbers of LLC Points on the date
the property was purchased.

         SECTION 4.6 TAX ALLOCATIONS. For income tax purposes only, each item of
income, gain, loss and deduction of the LLC shall be allocated among the Members
in the same manner as the corresponding items of income, gain, loss and
deduction and specially allocated items are allocated for Capital Account
purposes, provided that in the case of any LLC asset the Carrying Value of which
differs from its adjusted tax basis for federal income tax purposes, income,
gain, loss and deduction with respect to such asset shall be allocated solely
for income tax purposes in accordance with the principles of Sections 704(b) and
(c) of the Code (in any manner determined by the Manager Member in its sole
discretion) so as to take account of the difference between the Carrying Value
and the adjusted basis of such asset.

         SECTION 4.7 OTHER ALLOCATION PROVISIONS. The foregoing provisions and
the other provisions of this Agreement relating to the maintenance of Capital
Accounts are intended to comply with Treasury Regulations Section 1.704-1(b) and
shall be interpreted and applied in a manner consistent with such regulations.
Sections 4.2(c) to 4.2(f), and Sections 4.5 and 4.6 may be amended at any time
by the Manager Member if necessary, in the opinion of tax counsel to the LLC, to
comply with such regulations, so long as any such amendment (a) does not
materially change the relative economic interests of the Members and (b) to the
extent practicable, in the Manager Member's reasonable good faith judgment,
applies consistently to all Non-Manager Members.


              ARTICLE V - TRANSFER OF LLC INTERESTS BY NON-MANAGER
               MEMBERS; RESIGNATION, REDEMPTION AND WITHDRAWAL BY
                              NON-MANAGER MEMBERS;
                  ADMISSION OF ADDITIONAL NON-MANAGER MEMBERS.

         SECTION 5.1 TRANSFERABILITY OF INTERESTS. No interest of a Non-Manager
Member in the LLC may, directly or indirectly, be sold, assigned, transferred,
gifted or exchanged, nor may any Non-Manager Member offer to do any of them
(each, a "Transfer"), nor may any interest in any Non-Manager Member be,
directly or indirectly, Transferred, nor may any stockholder in any Non-Manager
Member which is not an individual offer to do any of them, and no Transfer by a
Non-Manager Member or stockholder of a Non-Manager Member shall be binding upon
the LLC or any Non-Manager Member unless it is expressly permitted by this
Article V and the Manager Member receives an executed copy of the documents
effecting such Transfer, which shall be in form and substance reasonably
satisfactory to the Manager Member. The transferee of an interest in the 



                                       41
<PAGE>

LLC may become a substitute Non-Manager Member, and a Non-Manager Member which
is not an individual may remain a Member of the LLC following the Transfer of an
interest in such Non-Manager Member, only upon the terms and conditions set
forth in Section 5.2. If a transferee of an interest of a Non-Manager Member in
the LLC does not become (and until any such transferee becomes) a substitute
Non-Manager Member, or if a Non-Manager Member in which an interest has been
Transferred does not remain a Member of the LLC following such Transfer, in
either case in accordance with the provisions of Section 5.2, such Person shall
not be entitled to exercise or receive any of the rights, powers or benefits of
a Non-Manager Member other than the right to receive distributions which the
assigning Non-Manager Member has sold, transferred or assigned to such Person in
compliance with this Section 5.1. No Non-Manager Member's interest in the LLC
or, in the case of a Non-Manager Member which is not an individual, none of the
direct or indirect interests of a beneficial owner of such Non-Manager Member,
may be Transferred except:

         (a) with the prior written consent of the Manager Member, which consent
may be granted or withheld by the Manager Member in its sole discretion;

         (b) upon the death of such beneficial owner, its interests in the LLC
or in the Non-Manager Member may be Transferred by will or the laws of descent
and distribution (without the consent of the Manager Member but subject, in all
cases, to the provisions of Section 3.11 hereof); or

         (c) a Non-Manager Member (and its beneficial owners) may Transfer
interests in the LLC or in such Non-Manager Member to members of his or her
Immediate Family (or trusts for their benefit and of which the beneficial owner
is the settlor and/or trustee, provided that any such trust does not require or
permit distribution of such interests) without the consent of the Manager
Member;

provided that in the case of (b) or (c) above, (i) the transferee first enters
into an agreement with the LLC in form and substance reasonably acceptable to
the Manager Member agreeing to be bound by the provisions hereof (and if such
transferee is not already a party to a Non-Solicitation Agreement and becomes an
employee of the LLC, or the Non-Manager Member in which such transferee acquired
an interest remains a Member of the LLC and the transferee becomes an employee
of the LLC, the transferee enters into a Non-Solicitation Agreement), and (ii)
whether or not the transferee enters into such an agreement, such LLC Interests,
and interests in such Non-Manager Member, shall thereafter remain subject to
this Agreement (and, if applicable the transferee becomes an employee of the
LLC, or the Non-Manager Member in which such transferee acquired an interest
remains a Member of the LLC and the transferee becomes an employee of the LLC,
the relevant Non-Solicitation Agreement) to the same extent they would be if
held by such Non-Manager Member or beneficial owner, as applicable.
Notwithstanding the foregoing, no Non-Manager Member's interest in the LLC may
be Transferred if, giving effect to such Transfer, the total number of Members
of the LLC would exceed one hundred (100) (as determined in accordance with
Treasury Regulations ss. 1.7704-1(h)), unless either such Transfer is a Transfer
described in Treasury Regulations ss. 1.7704- 1(e) or such Transfer is pursuant
to a Put right under Article VII and the sum of the percentage interests in
profits or capital of the LLC Transferred during the taxable year of the LLC
(other than in Transfers described in Treasury Regulations ss. 1.7704-1(e))
would, taking the Transfer in question into account and assuming the maximum
exercise of the Non-Manager Members' Put rights under Article VII, exceed ten
percent (10%) of the total interests in profits or capital of the LLC.



                                       42
<PAGE>

         For all purposes of this LLC Agreement, any Transfers of LLC Interests
shall be deemed to occur as of the end of the last day of the calendar quarter
in which any such Transfer would otherwise have occurred. Upon any Transfer of
LLC Interests, the Manager Member shall make the appropriate revisions to
SCHEDULE A hereto.

         Each time LLC Interests (including without limitation additional LLC
Points) are Transferred (including without limitation pursuant to a Put) or
Repurchased, the Manager Member may, in its sole discretion, elect to revalue
the Capital Accounts of all Members. If the Manager Member so elects, then the
Capital Accounts of all the Members shall be adjusted as follows: (i) the
Manager Member shall determine the proceeds which would be realized if the LLC
sold all its assets at such time for a price equal to the Fair Market Value of
such assets, and (ii) the Manager Member shall allocate amounts equal to the
gain or loss which would have been realized upon such a sale to the Capital
Accounts of all the Members immediately prior to such Transfer in accordance
with Sections 4.2(e) and 4.2(f) hereof.

         No interests of a Non-Manager Member in the LLC may be pledged,
hypothecated, optioned or encumbered, nor may any interests in a Non-Manager
Member be pledged, hypothecated, optioned or encumbered, nor may any offer to do
any of the foregoing be made, without the prior written consent of the
Management Committee and the Manager Member.

         SECTION 5.2 SUBSTITUTE NON-MANAGER MEMBERS. No transferee of interests
of a Non-Manager Member shall become a Member, and no Non-Manager Member in
which any interests have been Transferred shall remain a Member of the LLC,
except in accordance with this Section 5.2. The Manager Member may, in its sole
discretion, admit as a substitute Non-Manager Member (with respect to all or a
portion of the LLC Interests held by a Person), any Person that acquires an LLC
Interest by Transfer from another Non-Manager Member pursuant to Section 5.1
hereof, or that acquires an LLC Interest from the Manager Member pursuant to
Section 6.1 hereof, and the Manager Member may, in its sole discretion, permit
any Non-Manager Member in which interests have been Transferred to remain a
Member of the LLC (and such Non-Manager Member otherwise shall cease to be a
Member of the LLC). The admission of a transferee as a substitute Non-Manager
Member shall, in all events, be conditioned upon the execution of an instrument
satisfactory in form and substance to the Manager Member whereby such transferee
becomes a party to this Agreement as a Non-Manager Member as well as compliance
by such transferee with the provisions of Section 3.8 hereof. Upon the admission
of a substitute Non-Manager Member, the Manager Member shall make the
appropriate revisions to SCHEDULE A hereto.

         SECTION 5.3 ALLOCATION OF DISTRIBUTIONS BETWEEN TRANSFEROR AND
TRANSFEREE; SUCCESSOR TO CAPITAL ACCOUNTS. Upon the Transfer of LLC Interests
pursuant to this Article V, distributions pursuant to Article IV after the date
of such Transfer shall be made to the Person owning the LLC Interest at the date
of distribution, unless the transferor and transferee otherwise agree and so
direct the LLC and the Manager Member in a written statement signed by both the
transferor and transferee. In connection with a Transfer by a Member of LLC
Points, the transferee shall succeed to a pro-rata (based on the percentage of
such Person's LLC Points transferred) portion of the transferor's Capital
Account, unless the transferor and transferee otherwise agree and so direct the
LLC and the Manager Member in a written statement signed by both the transferor
and transferee and consented to by the Manager Member.

         SECTION 5.4 RESIGNATION, REDEMPTIONS AND WITHDRAWALS. No Non-Manager
Member shall have the right to resign, to cause the redemption of its interest
in the LLC, in whole or in part, or to withdraw from the LLC, except (a) with
the consent of the Manager Member, (b) as is expressly provided for in Section
3.11 hereof; or (c) as is expressly provided for in Section 7.1 hereof. Upon any
resignation, redemption or withdrawal, the Non-Manager Member shall only be
entitled to the consideration, if any, provided for by Section 3.11 or Section
7.1 hereof, if and to the extent that one of such Sections is applicable. Upon
the resignation, redemption or withdrawal, in whole or in part, by a Non-Manager
Member, the Manager Member shall make the appropriate revisions to SCHEDULE A
hereto.

         SECTION 5.5 ISSUANCE OF ADDITIONAL LLC INTERESTS.

                  (a) Additional Non-Manager Members (the "Additional
Non-Manager Members" and each an "Additional Non-Manager Member") may be
admitted to the LLC, and such Additional Non-Manager Members may be issued LLC
Points, only (i) upon receipt of a Majority Vote and the consent of the Manager
Member and the Management Committee and upon such terms and conditions as may be
established by the Manager Member (including, without limitation, upon such
Additional Non-Manager Member's execution of an instrument in form and substance
satisfactory to the Manager Member whereby such Person becomes a party to this
Agreement as a Non-Manager Member as well as such Person's compliance with the
provisions of Section 3.8 hereof), or (ii) with respect to Program LLC Points in
the Purchase Reserve which have not yet been issued, in accordance with and
subject to the provisions of the Purchase Program.

                  (b) Existing Non-Manager Members may be issued additional LLC
Points (or other LLC Interests), only (i) by the LLC with the consent of, and
upon such terms and conditions as may be established by the Management Committee
and the Manager Member, or (ii) with respect to Program LLC Points in the
Purchase Reserve which have not yet been issued, in accordance with and subject
to the provisions of the Purchase Program. The Manager Member or its Affiliates
may only be issued additional LLC Points (or other LLC Interests) upon the
receipt of a Majority Vote.

                  (c) Each time additional LLC Interests are issued (including,
without limitation, additional LLC Points), the Capital Accounts of all the
Members shall be adjusted as follows: (i) the Manager Member shall determine the
proceeds which would be realized if the LLC sold all its assets at such time for
a price equal to the Fair Market Value of such assets, and (ii) the Manager
Member shall allocate amounts equal to the gain or loss which would have been
realized upon such a sale to the Capital Accounts of all the Members immediately
prior to such issuance in accordance with Sections 4.2(e) and 4.2(f) hereof.

                  (d) Upon the issuance of additional LLC Interests, the Manager
Member shall make the appropriate revisions to SCHEDULE A hereto.

                  (e) Notwithstanding anything in this Agreement to the
contrary, (i) no additional LLC Interests may be issued if, giving effect to
such Transfer, the total number of Members would exceed one hundred (100) as
determined in accordance with Treasury Regulation Section 1.7704-1 (h)(3) and
(ii) no LLC Interests may be issued (A) in a transaction that is required to be
registered under the Securities Act or (B) in a transaction that is not required
to be registered under the Securities Act by reason of Regulation S thereunder
unless the offering and sale of the LLC Interests 



                                       44
<PAGE>

would not have been required to be registered under the Securities Act if the
LLC Interests had been offered and sold within the United States.

                  SECTION 5.6 ADDITIONAL REQUIREMENTS FOR TRANSFER OR FOR
ISSUANCE. As additional conditions to the validity of (x) any Transfer of a
Non-Manager Member's interest in the LLC (or, in the case of a Non-Manager
Member which is not an individual, the interests of the direct or indirect
beneficial owners of such Non-Manager Member) (pursuant to Section 5.1 above),
or (y) the issuance of additional LLC Interests (pursuant to Section 5.5 above),
such Transfer or issuance shall not: (i) violate the registration provisions of
the Securities Act or the securities laws of any applicable jurisdiction, (ii)
cause the LLC to become subject to regulation as an "investment company" under
the 1940 Act, and the rules and regulations of the SEC thereunder, (iii) result
in the termination of any contract to which the LLC is a party and which
individually or in the aggregate are material (it being understood and agreed
that any contract pursuant to which the LLC provides Investment Management
Services is material), or (iv) result in the treatment of the LLC as an
association taxable as a corporation or as a "publicly traded partnership" for
federal income tax purposes.

                  The Manager Member may require reasonable evidence as to the
foregoing, including, without limitation, a favorable opinion of counsel, which
expense shall be borne by the parties to such transaction (and to the extent the
LLC is such a party, shall be paid from the Operating Allocation).

                  To the fullest extent permitted by law, any Transfer or
issuance that violates the provisions of this Article V shall be null and void.

                  SECTION 5.7 REPRESENTATION OF MEMBERS. The Manager Member and
each Non-Manager Member (including each Additional Non-Manager Member) hereby
represents and warrants to the LLC and each other Member, and acknowledges, that
(a) it has such knowledge and experience in financial and business matters that
it is capable of evaluating the merits and risks of an investment in the LLC and
making an informed investment decision with respect thereto, (b) it is able to
bear the economic and financial risk of an investment in the LLC for an
indefinite period of time, (c) it is acquiring an interest in the LLC for
investment only and not with a view to, or for resale in connection with, any
distribution to the public or public offering thereof, (d) the equity interests
in the LLC have not been registered under the securities laws of any
jurisdiction and cannot be disposed of unless they are subsequently registered
and/or qualified under applicable securities laws and the provisions of this
Agreement have been complied with, and (e) the execution, delivery and
performance of this Agreement by such Member have been duly authorized in all
necessary respects, do not require it to obtain any consent or approval that has
not been obtained and do not contravene or result in a default under any
provision of any existing law or regulation applicable to it, any provision of
its charter, by-laws or other governing documents or any agreement or instrument
to which it is a party or by which it is bound, and this Agreement has been duly
executed and delivered by such Member and is enforceable against such Member in
accordance with its terms, except as enforcement may be limited by bankruptcy,
insolvency, reorganization, moratorium or other laws relating to or limiting
creditors' rights generally or by equitable principles relating to

                 ARTICLE VI - TRANSFER OF LLC INTERESTS BY THE
                      MANAGER MEMBER; REDEMPTION, REMOVAL
                                 AND WITHDRAWAL

         SECTION 6.1 TRANSFERABILITY OF INTEREST.

                  (a) Except as set forth in this Section 6.1, without the
written approval of the Management Committee, none of the Manager Member's
interest in the LLC (including, without limitation, any interest which has been
Transferred to the Manager Member) may be Transferred; PROVIDED, HOWEVER, (i) it
is understood and agreed that, in connection with the operation of the business
of AMG and the Manager Member (including, without limitation, the financing of
its interest herein and direct or indirect interests in additional investment
management companies), the Manager Member's interest in the LLC will be pledged
and encumbered and lien holders of the Manager Member's interest shall have and
be able to exercise the rights of secured creditors with respect to such
interest, (ii) the Manager Member may sell some (but not a majority) of its LLC
Interests to a Person who is not a Member but who is an Officer or employee of
the LLC or who becomes an Officer or employee of the LLC in connection with such
issuance, or a Person wholly owned by any such Person, (iii) the Manager Member
may sell some (but not a majority) of its LLC Interests to existing Non-Manager
Members, and (iv) the Manager Member may sell all or any portion of its LLC
Interests to an Affiliate of the Manager Member. Notwithstanding anything else
set forth herein, the Manager Member may, with a Majority Vote, Transfer all its
interests in the LLC in a single transaction or a series of related
transactions, and, in any such case, each of the Non-Manager Members shall be
required to Transfer, in the same transaction or transactions, all their
interests in the LLC, provided that the price to be received by all the Members
shall be allocated among the Members as follows: (a) an amount equal to the sum
of the positive balances, if any, in positive Capital Accounts shall be
allocated among the Members having such Capital Accounts in proportion to such
positive balances, and (b) the excess, if any, shall be allocated among all
Members in accordance with their respective number of LLC Points at the time of
such sale. Upon any of the foregoing transactions, the Manager Member shall make
the appropriate revisions to SCHEDULE A hereto.

                  (b) In the case of a Transfer upon foreclosure, pursuant to
Section 6.1(a)(i) above, each Transferee shall sign a counterpart signature page
to this Agreement agreeing thereby to become either a Non-Manager Member or a
Manager Member (provided, however, that once one such other Transferee elects to
become a Manager Member, no Transferee (other than a subsequent Transferee of
such new Manager Member) may elect to be a Manager Member hereunder. If the
Transferee pursuant to Section 6.1(a)(i) above receives all of the Manager
Members LLC Interests, and none of such Transferees elects to become a Manager
Member, then the Manager Member shall be deemed to have withdrawn from the LLC.
If, however, one of the Transferees elects to become a Manager Member and
executes a counterpart signature page to this Agreement agreeing thereby to
become a Manager Member, then notwithstanding any other provision hereof to the
contrary, the old Manager Member shall thereupon be permitted to withdraw from
the LLC as Manager Member.

<PAGE>

                  (c) In the case of a Transfer pursuant to the penultimate
sentence of Section 6.1(a) above, the Manager Member shall be deemed to have
withdrawn, and its transferee shall be deemed to have become the Manager Member.

from the LLC as Manager Member. With a prior Majority Vote, the Manager Member
may resign or withdraw as Manager Member upon prior written notice to the LLC.
Without a prior Majority Vote, the Manager Member shall have no right to have
all or any portion of its interest in the LLC redeemed. Any resigned, withdrawn
or removed Manager Member shall retain its interest in the capital of the LLC
and its other economic rights under this Agreement as a Non-Manager Member
having the number of LLC Points held by the Manager Member prior to its
resignation, withdrawal or removal. If a Manager Member who has resigned,
withdrawn or been removed no longer has any economic interest in the LLC, then
upon such resignation, withdrawal or removal such Person shall cease to be a
Member of the LLC.

thirty-three one hundredths percent (33.33%) of the LLC's Earned Performance

the number of Vested LLC Points to be purchased from such Non-Manager Member on
the Purchase Date, and the denominator of which is the number of LLC Points
outstanding on the Purchase Date (before giving effect to any Puts or any
issuances, redemptions or vesting of LLC Points on such date).

                  (f) In the case of any Put, the Put Price shall be paid by AMG
(or, if AMG shall have assigned its obligation to the Manager Member, the LLC or
any other Person pursuant to paragraph (g) below, the Manager Member, the LLC or
such other Person (or their respective assigns) on the relevant Purchase Date by
certified check issued to such Non-Manager Member, in each case, against
delivery of such documents or instruments of transfer as may reasonably be
requested by AMG, the Manager Member or the LLC, as applicable, and in each case
(i) including representations that the transferring Non-Manager Member is the
record and beneficial owner of the LLC Interests being Put, free and clear of
any Liens other than those imposed by this Agreement and (ii) addressing such
other matters as the Manager Member, the LLC or AMG, as applicable, reasonably
requests.

                  (g) AMG may assign and/or delegate any or all of its rights
and obligations to purchase LLC Points under this Section 7.1, in one or more
instances, to the Manager Member or to any other Person (with the consent of the
Management Committee if to any Person not then a Member), provided that (i) no
such consent shall be required for an assignment or delegation to a Person who
is (A) an Officer or employee of the LLC or becomes an Officer or employee in
connection with such assignment or delegation or a Person wholly owned by any
such Person or (B) an Affiliate of the Manager Member, and (ii) no such
assignment or delegation shall relieve AMG of its obligation to make the payment
for a Put as required by this Section 7.1. The Manager 



                                       48
<PAGE>

Member may, with a Majority Vote, assign any or all of its rights and
obligations to purchase LLC Points under this Section 7.1, in one or more
instances, to the LLC.

                  (h) In the case of any Put, as of any Purchase Date, the
Non-Manager Member shall cease to hold the LLC Points purchased on the Purchase
Date, and shall cease to hold a pro-rata portion of such Non-Manager Member's
Capital Account (which shall have been transferred to AMG (or, upon assignment
of any of AMG's obligations to the Manager Member or the LLC pursuant to
paragraph (g) hereof, transferred to the Manager Member or canceled by the LLC))
and shall no longer have any rights with respect to such portion of its LLC
Interests.

consent of the Manager Member; or

                  (b) at any time there are no Members of the LLC, unless the

commence to wind up the LLC's affairs; PROVIDED, HOWEVER, that a reasonable time
shall be allowed for the orderly liquidation of the assets of the LLC and the

proportions, as specified in Article IV hereof, as before liquidation. The
proceeds of liquidation shall be distributed as set forth in Section 4.4 hereof.

         SECTION 8.5 TERMINATION. The LLC shall terminate when all of the assets

look solely to the LLC's assets for the return of their Capital Contributions
and Capital Accounts, and if the assets of the LLC remaining after payment of or

insufficient to return such Capital Contributions or Capital Accounts, the
Members and former Members shall have no recourse against the LLC or any other
Member (including, without limitation, the Manager Member).


                        ARTICLE IX - RECORDS AND REPORTS.

         SECTION 9.1 BOOKS AND RECORDS. The Officers and the Members shall cause

consistent with the generally accepted accounting principles and with the

                           (ii)a balance sheet as of the last day of such month
                  or quarter; and

                           (iii)with respect to the quarterly financial report,
                  a detailed computation of the Owners' Allocation for such
                  quarter.

                  (b) Within thirty (30) days after the end of each fiscal year

                  (c) If requested by the Manager Member, within twenty-five
(25) days after the end of each calendar quarter, the LLC's operating budget for
each of the next four (4) fiscal quarters, in such form and containing such
estimates as may be requested by the Manager Member from time to time, certified
by the most senior financial officer of the LLC.

                  (d) If requested by the LLC, copies of all financial
statements, reports, notices, press releases and other documents released to the

                  (e) As promptly as is reasonably possible following request by
the Manager Member from time to time, such financial, operations, performance or
other information or data as may be requested.

         SECTION 9.4 MEETINGS.

                  (a) The LLC and its Officers shall hold such regular meetings
at the LLC's principal place of business with representatives of the Manager
Member as may be reasonably requested by the Manager Member from time to time.
These meetings shall be attended (either in person or by telephone) by such
members of the Management Committee, Officers and other employees of the LLC as
may be requested by the Manager Member or any of the Officers.

                  (b) At each meeting, the Officers and other employees of the
LLC shall discuss such matters regarding the LLC and its performance, operations
and/or budgets as may be reasonably requested by the Manager Member, and each of
the attendees (whether in person or by telephone) at such meeting shall have the
right to submit proposals and suggestions regarding the LLC, and the attendees
at the meeting shall, in good faith, discuss and consider such proposals and
suggestions.

         SECTION 9.5 TAX MATTERS.

                  (a) The Manager Member shall cause to be prepared and filed on
or before the due date (or any extension thereof) federal, state, local and
foreign tax or information returns required to be filed by the LLC. The Manager
Member, to the extent that LLC funds are available, shall cause the LLC to pay
any taxes payable by the LLC (it being understood that the expenses of




                                       51
<PAGE>

preparation and filing of such tax returns, and the amounts of such taxes, are
to be treated as operating expenses of the LLC to be paid from the Operating
Allocation), provided that the Manager Member shall not be required to cause the
LLC to pay any tax so long as the Manager Member or the LLC is in good faith and
by appropriate legal proceedings contesting the validity, applicability or
amount thereof and such contest does not materially endanger any right or
interest of the LLC and adequate reserves therefor have been set aside by the
LLC. Neither the LLC nor any Employee Stockholder or Non-Manager Member shall do
anything or take any action which would be inconsistent with the foregoing or
with the Manager Member's actions as authorized by the foregoing provisions of
this Section 9.5(a).

                  (b) The Manager Member shall be the tax matters partner for
the LLC pursuant to Sections 6221 through 6233 of the Code.

                  (c) The Manager Member shall, in its sole discretion, make or
cause to be made any and all elections for federal, state, local and foreign tax
matters, including any election to adjust the basis of LLC property pursuant to
Sections 743(b), 743(b) and 754 of the Code or comparable provisions of state,
local or foreign law.


            ARTICLE X - LIABILITY, EXCULPATION AND INDEMNIFICATION.

         SECTION 10.1 LIABILITY. Except as otherwise provided by the Act, the
debts, obligations and liabilities of the LLC, whether arising in contract, tort
or otherwise, shall be solely the debts, obligations and liabilities of the LLC,
and no Covered Person shall be obligated personally for any such debt,
obligation or liability of the LLC solely by reason of being a Covered Person.

         SECTION 10.2 EXCULPATION.

                  (a) No Covered Person shall be liable to the LLC or any other
Covered Person for any loss, damage or claim incurred by reason of any act or
omission performed or omitted by such Covered Person in good faith on behalf of
the LLC and in a manner reasonably believed to be within the scope of authority
conferred on such Covered Person by this Agreement, except that a Covered Person
shall be liable for any such loss, damage or claim incurred by reason of any
action or inaction of such Covered Person which constituted fraud, gross
negligence, willful misconduct or a breach of this Agreement, the Stock Purchase
Agreement or, in the case of a Non-Manager Member or Employee Stockholder, the
Employment Agreement and/or Non-Solicitation Agreement to which he, she or it is
a party.

                  (b) A Covered Person shall be fully protected in relying in
good faith upon the records of the LLC and upon such information, opinions,
reports or statements presented to the Covered Person by any Person as to
matters the Covered Person reasonably believes are within such other Person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the LLC of such Covered Person.



                                       52
<PAGE>

SECTION 10.3 FIDUCIARY DUTY.

                  (a) To the extent that, at law or in equity, a Covered Person
has duties (including fiduciary duties) and liabilities relating thereto to the
LLC or to any Member, a Covered Person acting under this Agreement shall not be
liable to the LLC or to any Member for its good faith reliance on the provisions
of this Agreement. The provisions of this Agreement, to the extent that they
restrict the duties and liabilities of a Covered Person otherwise existing at
law or in equity, are agreed by the parties hereto to replace such other duties
and liabilities of such Covered Person.

                  (b) Unless otherwise expressly provided herein, (i) whenever a
conflict of interest exists or arises between the Manager Member and any other
Member, or (ii) whenever this Agreement or any other agreement contemplated
herein or therein provides that the Manager Member shall act in a manner that
is, or provides terms that are, fair and reasonable to the LLC or any Member,
the Manager Member shall resolve such conflict of interest, take such action or
provide such terms, considering in each case the relative interest of each party
(including its own interest) to such conflict, agreement, transaction or
situation and the benefits and burdens relating to such interests, any customary
or accepted industry practices, and any applicable generally accepted accounting
practices or principles. The resolution, action or term so made, taken or
provided by the Manager Member shall not constitute a breach of this Agreement
or any other agreement contemplated herein or of any duty or obligation of the
Manager Member at law or in equity or otherwise unless the Managing Member did
not act in good faith.

                  (c) Whenever in this Agreement the Manager Member is permitted
or required to make a decision (i) in its "discretion" or under a grant of
similar authority or latitude, the Manager Member shall be entitled to consider
such interests and factors as it desires, including its own interests, or (ii)
in its "good faith" or under another express standard, the Manager Member shall
act under such express standard and shall not be subject to any other or
different standard imposed by this Agreement or other applicable law.

                  (d) Wherever in this Agreement a factual determination is
called for and the applicable provision of this Agreement does not indicate what
party or parties are to make the applicable factual determination, and/or the
applicable standard to be used in making the factual determination, such
determination shall be made by the Manager Member in the exercise of reasonable
discretion.

         SECTION 10.4 INDEMNIFICATION. To the fullest extent permitted by
applicable law, a Covered Person shall be entitled to indemnification from the
LLC for any loss, damage or claim (including any amounts paid in settlement of
any such claims) including expenses, fines, penalties and counsel fees and
expenses incurred by such Covered Person ("Losses") by reason of any act or
omission performed or omitted by such Covered Person in good faith on behalf of
the LLC and in a manner reasonably believed to be within the scope of authority
conferred on such Covered Person by this Agreement, except that no Covered
Person shall be entitled to be indemnified in respect of any Losses incurred by
such Covered Person by reason of any action or inaction of such Covered Person
which constituted fraud, gross negligence, willful misconduct or a breach of
this Agreement, the Stock Purchase Agreement or, in the case of the Non-Manager
Member or Employee Stockholder, the Employment Agreement and/or Non-Solicitation
Agreement to which he, she or it is a party; PROVIDED, HOWEVER, that any
indemnity under this Section 10.4 shall be provided out of 


                                       53
<PAGE>

and to the extent of LLC assets only, and no Member or Covered Person shall have
any personal liability to provide indemnity on account thereof. To the fullest
extent permitted by applicable law, the LLC shall, out of Operating Allocation
(and, to the extent Operating Allocation is insufficient for such purpose, out
of the Non-Manager Members' portion of Owners' Allocation), indemnify, defend
and hold the Manager Member and its related Covered Persons harmless from and
against any and all Losses arising from, relating to or otherwise in connection
with the License Agreement, the payment of any Royalty by the LLC pursuant
thereto or the Manager Member's or any of its Affiliates' ownership of the
Intellectual Property (as defined in the License Agreement) (provided that, for
such purpose, Losses shall include without limitation any taxes (including
without limitation any interest or penalties thereon or relating thereto)
incurred by the Manager Member or any of its related Covered Persons as a result
of the payment of any Royalty by the LLC, the Manager Member's or any of its
Affiliates' ownership of the Intellectual Property or the existence of the
License Agreement in excess of the taxes that would have been incurred by the
Manager Member or such related Covered Person absent the existence of the
License Agreement).

         SECTION 10.5 NOTICE; OPPORTUNITY TO DEFEND AND EXPENSES.

                  (a) Promptly after receipt by any Covered Person from any
third party of notice of any demand, claim or circumstance that, immediately or
with the lapse of time, would reasonably be expected to give rise to a claim or
the commencement (or threatened commencement) of any action, proceeding or
investigation (an "Asserted Liability") that could reasonably be expected to
result in any Losses with respect to which the Covered Person might be entitled
to indemnification from the LLC under Section 10.4, the Covered Person shall
give notice thereof (the "Claims Notice") to the LLC; PROVIDED, HOWEVER, that a
failure to give such notice shall not prejudice the Covered Person's right to
indemnification hereunder except to the extent that the LLC is actually
prejudiced thereby. The Claims Notice shall describe the Asserted Liability in
such reasonable detail as is practicable under the circumstances, and shall, to
the extent practicable under the circumstances, indicate the amount (estimated,
if necessary) of the Loss that has been or may be suffered by the Covered
Person.

                  (b) The LLC may elect to compromise or defend, at its own
expense and by its own counsel, any Asserted Liability; PROVIDED, HOWEVER, that
if the named parties to any action or proceeding include (or could reasonably be
expected to include) both the LLC and a Covered Person, or more than one Covered
Persons, and the LLC is advised by counsel that representation of both parties
by the same counsel would be inappropriate under applicable standards of
professional conduct, the Covered Person may engage separate counsel at the
expense of the LLC. If the LLC elects to compromise or defend such Asserted
Liability, it shall within twenty (20) business days (or sooner, if the nature
of the Asserted Liability so requires) notify the Covered Person of its intent
to do so, and the Covered Person shall cooperate, at the expense of the LLC, in
the compromise of, or defense against, such Asserted Liability. If the LLC
elects not to compromise or defend the Asserted Liability, fails to notify the
Covered Person of its election as herein provided, contests its obligation to
provide indemnification under this Agreement, or fails to make or ceases making
a good faith and diligent defense, the Covered Person may pay, compromise or
defend such Asserted Liability all at the expense of the Covered Person (in
accordance with the provisions of Section 10.5(c) below). Except as set forth in
the preceding sentence, neither the LLC nor the Covered Person may settle or
compromise any claim over the objection of the LLC or the Manager Member;
PROVIDED, HOWEVER, that consent to settlement or compromise shall not be
unreasonably withheld. In any event, the LLC 



                                       54
<PAGE>

and the Covered Person may participate at their own expense, in the defense of
such Asserted Liability. If the Covered Person chooses to defend any claim, the
Covered Person shall make available to the LLC any books, records or other
documents within its control that are necessary or appropriate for such defense,
all at the expense of the LLC.

                  (c) If the LLC elects not to compromise or defend an Asserted
Liability, or fails to notify the Covered Person of its election as above
provided, then, to the fullest extent permitted by applicable law, expenses
(including legal fees) incurred by a Covered Person in defending any Asserted
Liability, shall, from time to time, be advanced by the LLC prior to the final
disposition of such claim, demand, action, suit or proceeding upon receipt by
the LLC of an undertaking by or on behalf of the Covered Person to repay such
amount if it shall be determined that the Covered Person is not entitled to be
indemnified as authorized in Section 10.4 hereof. The LLC may, if the Manager
Member deems it appropriate, require any Covered Person for whom expenses are
advanced, to deliver adequate security to the LLC for his or her obligation to
repay such indemnification.

         SECTION 10.6 MISCELLANEOUS.

                  (a) The right of indemnification hereby provided shall not be
exclusive of, and shall not affect, any other rights to which a Covered Person
may be entitled. Nothing contained in this Article X shall limit any lawful
rights to indemnification existing independently of this Article X.

                  (b) The indemnification rights provided by this Article X
shall also inure to the benefit of the heirs, executors, administrators,
successors and assigns of a Covered Person and any officers, directors, members,
partners, shareholders, employees and Affiliates of such Covered Person (and any
former officer, director, member, partner, shareholder or employee of such
Covered Person, if the Loss was incurred while such Person was an officer,
director, member, partner, shareholder or employee of such Covered Person). The
Manager Member may extend the indemnification called for by Section 10.4 to
non-employee agents of the LLC, the Manager Member or its Affiliates.


                           ARTICLE XI - MISCELLANEOUS.


                  SECTION 11.1 NOTICES. All notices, requests, elections,
consents or demands permitted or required to be made under this Agreement
("Notices") shall be in writing, signed by the Person or Persons giving such
notice, request, election, consent or demand and shall be delivered personally
or by confirmed facsimile, or sent by registered or certified mail, or by
commercial courier to the other Members, at their addresses set forth on the
signature pages hereof or on SCHEDULE A hereto, or at such other addresses as
may be supplied by written notice given in conformity with the terms of this
Section 11.1. All Notices to the LLC shall be made to the Manager Member at the
address set forth on the signature pages hereof or on SCHEDULE A hereto, with a
copy (which shall not constitute notice) to the President of the LLC at the
principal offices of the LLC. The date of any such personal or facsimile
delivery or the date of delivery by an overnight courier or the date five 



                                       55
<PAGE>

(5) days after the date of mailing by registered or certified mail, as the case
may be, shall be the date of such notice.

         SECTION 11.2 SUCCESSORS AND ASSIGNS. Subject to the restrictions on
Transfer set forth herein, this Agreement shall be binding upon and shall inure
to the benefit of the Members, their respective successors, successors-in-title,
heirs and assigns, and each and every successors-in-interest to any Member,
whether such successor acquires such interest by way of gift, purchase,
foreclosure or by any other method, and each shall hold such interest subject to
all of the terms and provisions of this Agreement.

         SECTION 11.3 AMENDMENTS. No amendments may be made to this Agreement
without the prior written consent of (i) the Manager Member, (ii) a Majority
Vote of the Non-Manager Members and (iii) AMG; PROVIDED, HOWEVER, that, without
the vote, consent or approval of any other Member, the Manager Member shall make
such amendments and additions to SCHEDULE A hereto as are required by the
provisions hereof; and, PROVIDED FURTHER, that, without the vote, consent or
approval of any other Member, the Manager Member may amend this Agreement to
cure any ambiguity, correct or supplement any provision hereof which is
incomplete or inconsistent with any other provision hereof or correct any
printing, stenographic or clerical errors or omissions.

         SECTION 11.4 NO PARTITION. No Member nor any successor-in-interest to
any Member, shall have the right while this Agreement remains in effect to have
the property of the LLC partitioned, or to file a complaint or institute any
proceeding at law or in equity to have the property of the LLC partitioned, and
each Member, on behalf of himself, his successors, representatives, heirs and
assigns, hereby waives any such right. It is the intent of the Members that
during the term of this Agreement, the rights of the Members and the Employee
Stockholders and their successors-in-interest, as among themselves, shall be
governed by the terms of this Agreement, and that the right of any Member or
successors-in-interest to assign, Transfer, sell or otherwise dispose of his
interest in the LLC shall be subject to the limitations and restrictions of this
Agreement.

         SECTION 11.5 NO WAIVER; CUMULATIVE REMEDIES. The failure of any Member
to insist upon strict performance of a covenant hereunder or of any obligation
hereunder, irrespective of the length of time for which such failure continues,
shall not be a waiver of such Member's right to demand strict compliance in the
future. No consent or waiver, express or implied, to or of any breach or default
in the performance of any obligation hereunder, shall constitute a consent or
waiver to or of any other breach or default in the performance of the same or
any other obligation hereunder. The rights and remedies provided by this
Agreement are cumulative and the use of any one right or remedy by any party
shall not preclude or waive its right to use any or all other remedies. Said
rights and remedies are given in addition to any other rights the parties may
have by law, statute, ordinance or otherwise.

         SECTION 11.6 DISPUTE RESOLUTION. All disputes arising in connection
with this Agreement shall be resolved by binding arbitration in accordance with
the applicable rules of the American Arbitration Association. The arbitration
shall be held in Boston, Massachusetts before a single arbitrator selected in
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 



                                       56
<PAGE>

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
11.6 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.

         SECTION 11.7 PRIOR AGREEMENTS SUPERSEDED. This Agreement, together with
the schedules and exhibits hereto, supersede the prior understandings and
agreements among the parties with respect to the subject matter hereof and
thereof, provided that the Stock Purchase Agreement, the Employment Agreements
and the Non-Solicitation/Non-Disclosure Agreements shall not be superseded and
shall survive in accordance with their respective terms.

         SECTION 11.8 CAPTIONS. Titles or captions of Articles or Sections
contained in this Agreement are inserted as a matter of convenience and for
reference, and in no way define, limit, extend or describe the scope of this
Agreement or the intent of any provision hereof.

         SECTION 11.9 COUNTERPARTS. This Agreement may be executed in a number
of counterparts, all of which together shall for all purposes constitute one
Agreement, binding on all the Members notwithstanding that all Members have not
signed the same counterpart.

         SECTION 11.10 APPLICABLE LAW; JURISDICTION. This Agreement and the
rights and obligations of the parties hereunder shall be governed by and
interpreted, construed and enforced in accordance with the laws of the State of
Delaware, without applying the choice of law or conflicts of law provisions
thereof. Each of the parties hereby consents to personal jurisdiction, service
of process and venue in the federal or state courts sitting in Boston,
Massachusetts for any claim, suit or proceeding arising under this Agreement to
enforce any arbitration award or obtain equitable relief and hereby irrevocably
agrees that all claims in respect of such action or proceeding may be heard and
determined in such state court or, to the extent permitted by law, in such
federal court (subject to the provisions of Section 11.6 hereof). To the extent
permitted by law, 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 11.1 hereof. The
parties agree that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions.

         SECTION 11.11 INTERPRETATION. All terms herein using the singular shall
include the plural; all terms using the plural shall include the singular; in
each case, the term shall be as appropriate to the context of each sentence.
Throughout this Agreement, nouns, pronouns and verbs shall be construed as

         SECTION 11.12 SEVERABILITY. The invalidity or unenforceability of any
particular provision of this Agreement shall not affect the other provisions

employ the Employee for the period of employment and upon and subject to the
terms herein provided.

will not compete with the Employer and its Controlled Affiliates during the
period of employment, and will not for a period thereafter compete with the
Employer or its Controlled Affiliates, or solicit any Past, Present, or
Potential Clients of the Company or the Employer and will not, by such
competition or solicitation, damage the Employer's goodwill among its clients
and the general public.

     WHEREAS, the Employee desires to be employed by the Employer and to refrain

meaning set forth in the LLC Agreement when used in this Employment Agreement.

     In consideration of the premises, the mutual covenants and the agreements
hereinafter set forth and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto covenant and
agree as follows:

     SECTION 1. TERM OF EMPLOYMENT; COMPENSATION. The Employer agrees to employ
the Employee for a period of ___ years beginning on the Closing Date (the
"Term") as an officer of the Employer except as provided herein; and the
Employee hereby accepts such employment. As consideration for the Employee's
performance hereunder, the Employer will pay the Employee for his services
during the Term hereof such amounts (which may be zero (0)) as shall be
determined by the Management Committee or its delegate(s) consistent with the
provisions of Article III of the LLC Agreement (including, by way of example and
not of limitation, the provisions of Section 3.5(c) of the LLC Agreement with
regard to the use of Operating Allocation), subject to such payroll and
withholding deductions as are required by law. Consistent with the provisions of
Section 3.5(c) of the LLC Agreement, the Employee's compensation (including
salary and bonus) will be periodically reviewed and adjusted (with respect to
both increases and/or decreases).

<PAGE>

     SECTION 2. OFFICE AND DUTIES (a) During the Term of this Employment 
Agreement, the Employee shall hold such positions and perform such duties 
relating to the Employer's businesses and operations as may from time to time 
be assigned to him in accordance with the provisions of Article III of the 
LLC Agreement. During the Term of this Employment Agreement and while 
employed by the Employer, the Employee shall devote substantially all of his 
working time to his duties hereunder and shall, to the best of his ability, 
perform such duties in a manner which will further the business and interests 
of the Employer. During the longer of the Term of this Employment Agreement 
or while Employee is employed by or acting as a consultant (or in any similar 
capacity) to the Employer or any of its Affiliates, the Employee shall not 
engage (i) in any Prohibited Competition Activity; (ii) interfere with the 
relations of the Employer or any of its Controlled Affiliates with any person 
or entity who at any time during such period was a Client (which means Past, 
Present, and Potential Clients); or (iii) solicit or induce or attempt to 
solicit or induce, directly or indirectly, any employee or agent of or 
consultant (or person acting in any similar capacity) to the Employer to 
terminate its, his or her relationship therewith. The Employee agrees that he 
will travel to whatever extent is reasonably necessary in the conduct of the 
Employer's business.

     (b) Except as provided in the LLC Agreement, during the Term of this
Agreement and while employed by the Employer, the Employee shall not, directly
or indirectly, solicit the business of any Past, Present, or Potential Clients
except on behalf and for the benefit of the Employer, or pursue any other
business activity, including, without limitation, serving as an officer,
director, employee, agent or adviser to any business entity other than the
Employer, without the Employer's prior written consent.

     (c) Notwithstanding the provisions of this Section 2, the Employee may
engage in investing for his personal account (and for the accounts of members of
his Immediate Family, provided that no compensation is received by him
therefore) if each such investment is made in accordance with the Code of Ethics
of the Employer.

     SECTION 3. BENEFITS. The Employee shall participate, to the extent he is
eligible and in a manner and to an extent that is fair and appropriate in light
of his position and duties with the Employer at such time, in all bonus,
pension, profit sharing, group insurance, or other fringe benefit plans which
the Employer may hereafter in its sole and absolute discretion make available
generally to its officers pursuant to the provisions of Article III of the LLC
Agreement, but the Employer will not be required to establish any such program
or plan. The Employee shall be entitled to such vacations and to such
reimbursement of expenses as the Employer's policies allow, from time to time,
to officers having comparable responsibilities and duties.

     SECTION 4. TERMINATION OF EMPLOYMENT. Notwithstanding any other provision
of this Employment Agreement, Employee's employment with the Employer shall be
terminated only in the following circumstances:

                  (a) At any time by the Company, or by the Management Committee
         (excluding for all purposes the Employee) with the prior written
         consent of the Company, if For Cause; or

<PAGE>

                  (b) At any time by the Management Committee (excluding for all
         purposes the Employee) with the prior written consent of the Company,
         if not For Cause; or

                  (c) At any time by the Company, or by the Management Committee
         (excluding for all purposes the Employee) with the prior written
         consent of the Company, upon the Permanent Incapacity of the Employee;
         or

                  (d)      Upon the death of the Employee.

     SECTION 5. ALL BUSINESS TO BE THE PROPERTY OF THE EMPLOYER; ASSIGNMENT OF
INTELLECTUAL PROPERTY; CONFIDENTIALITY.

     (a) The Employee agrees that any and all presently existing investment
advisory businesses of the Employer and its Controlled Affiliates (including its
predecessor, the Company or any predecessor thereto), and all businesses
developed by the Employer and its or such predecessor's Controlled Affiliates,
including by such Employee or any other employee of the Employer (including,
without limitation, employees of its predecessor, the Company or any predecessor
thereto), including, without limitation, all investment methodologies, all
investment advisory contracts, fees and fee schedules, commissions, records,
data, client lists, agreements, trade secrets, and any other incident of any
business developed by the Employer (or its predecessor, the Company or any
predecessor thereto) or their respective Controlled Affiliates or earned or
carried on by the Employee for the Employer or its predecessor, the Company or
any predecessor thereto or their respective Controlled Affiliates, and all trade
names, service marks and logos under which the Employer or its Controlled
Affiliates do business, and any combinations or variations thereof and all
related logos, are and shall be the exclusive property of the Employer or such
Controlled Affiliate, as applicable, for its or their sole use, and (where
applicable) shall be payable directly to the Employer or such Controlled
Affiliate. In addition, the Employee acknowledges and agrees that the investment
performance of the accounts managed by the Employer (and its predecessor, the
Company or any predecessor thereto) was attributable to the efforts of the team
of professionals at the Employer (or its predecessor, the Company or any
predecessor thereto, as applicable) and not to the efforts of any single
individual or subset of such team of professionals, and that therefore, the
performance records of the accounts managed by the Employer (and its
predecessor, the Company and any predecessor thereto) are and shall be the
exclusive property of the Employer.

     (b) The Employee acknowledges that, in the course of performing services
hereunder and otherwise (including, without limitation, for the Employer's
predecessor, the Company or any predecessor thereto), the Employee has had, and
will from time to time have, access to information of a confidential or
proprietary nature, including without limitation, all confidential or
proprietary investment methodologies, trade secrets, proprietary or confidential
plans, client identities and information, client lists, service providers,
business operations or techniques, records and data ("Intellectual Property")
owned or used in the course of business by the Employer or its Controlled
Affiliates. The Employee agrees always to keep secret and not ever publish,
divulge, furnish, use or make accessible to anyone (otherwise than in the
regular business of the Employer and its Controlled Affiliates or as required by
court order or by law (on the written advice of outside counsel)) any
Intellectual Property of the Employer or any 

<PAGE>

Controlled Affiliate thereof unless such information can be shown to be in the
public domain through no fault of such Employee. At the termination of the
Employee's services to the Employer, all data, memoranda, client lists, notes,
programs and other papers, items and tangible media, and reproductions thereof
relating to the foregoing matters in the Employee's possession or control, shall
be returned to the Employer and remain in its possession.

     (c) The Employee acknowledges that, in the course of entering into this
Employment Agreement, the Employee has had and, in the course of the operation
of the Employer, the Employee will from time to time have, access to
Intellectual Property owned by or used in the course of business by AMG. The
Employee agrees, for the benefit of the Employer and its Members, and for the
benefit of the Manager Member and AMG, always to keep secret and not ever
publish, divulge, furnish, use or make accessible to anyone (otherwise than at
the Manager Member's request or by court order or by law (on the written advice
of outside counsel)) any knowledge or information regarding Intellectual
Property (including, by way of example and not of limitation, the transaction
structures utilized by AMG) of AMG unless such information can be shown to be in
the public domain through no fault of such Employee. At the termination of the
Employee's service to the Employer, all data, memoranda, documents, notes and
other papers, items and tangible media, and reproductions thereof relating to
the foregoing matters in the Employee's possession or control shall be returned
to AMG and remain in its possession.

     (d) The provisions of this Section 5 shall not be deemed to limit any of
the rights of the Employer or the Members under the LLC Agreement or under
applicable law, but shall be in addition to the rights set forth in the LLC
Agreement and those which arise under applicable law.

                      SECTION 6. NON-COMPETITION COVENANT.

     (a) Until the later of (i) two (2) years following the termination of the
Employee's employment with the Employer or any of its Affiliates or (ii) __
years from the date hereof, the Employee shall not, directly or indirectly,
engage in any Prohibited Competition Activity. [Blank to be two years after
stated term of Employment Agreement.]

     (b) In addition to, and not in limitation of, the provisions of Section
6(a), the Employee agrees, for the benefit of the Employer and the Company, that
from and after the termination of the Employee's employment with the Employer
and its Affiliates and until the later of (i) two (2) years following the
termination of the Employee's employment with the Employer or any of its
Affiliates or (ii) __ years from the date hereof, the Employee shall not,
directly or indirectly, whether as owner, part owner, shareholder, partner,
member, director, officer, trustee, employee, agent or consultant, or in any
other capacity, on behalf of himself or any Person other than the Employer and
its Controlled Affiliates: [Blank to be two years after stated term of
Employment Agreement.]

                      (i) provide Investment Management Services to any Person
         that is a Past, Present or Potential Client of the Employer; PROVIDED,
         HOWEVER, that this clause (i) shall not be applicable to clients of the
         Employer (including Potential Clients) who are also members of the
         Immediate Family of the Employee;

<PAGE>

                     (ii) solicit or induce, whether directly or indirectly, any
         Person for the purpose (which need not be the sole or primary purpose)
         of (A) causing any funds with respect to which the Employer or any of
         its Controlled Affiliates provides Investment Management Services to be
         withdrawn from such management, or (B) causing any Client of the
         Employer (including any Potential Client) not to engage the Employer or
         any of its Controlled Affiliates to provide Investment Management
         Services for any or additional funds;

                    (iii) contact or communicate with, in either case in
         connection with Investment Management Services, whether directly or
         indirectly, any Past, Present or Potential Clients of the Employer;
         PROVIDED, HOWEVER, that this clause (iii) shall not be applicable to
         clients of the Employer (including Potential Clients) who are also
         members of the Immediate Family of the Employee; or

                     (iv) solicit or induce, or attempt to solicit or induce,
         directly or indirectly, any employee or agent of, or consultant to, the
         Employer or any of its Controlled Affiliates to terminate its, his or
         her relationship therewith, hire any such employee, agent or
         consultant, or former employee, agent or consultant, or work in any
         enterprise involving investment advisory services with any employee,
         agent or consultant or former employee, agent or consultant, of the
         Employer or its Controlled Affiliates who was employed by or acted as
         an agent or consultant to the Employer (or its predecessor, the Company
         or any predecessor thereto) or its Affiliates at any time during the
         two (2) year period preceding the termination of the Employee's
         employment (excluding for all purposes of this sentence, secretaries
         and persons holding other similar positions).

     For purposes of this Section 6(b), (x) the term "Past Client" shall be
limited to those past clients who were recipients of Investment Management
Services, directly or indirectly, from the Employer (including its predecessor,
the Company or any predecessor thereto) and/or their respective Controlled
Affiliates at the date of termination of the Employee's employment or at any
time during the two (2) years immediately preceding the date of such
termination; and (y) the term "Potential Client" shall be limited to those
Persons to whom an offer was made (or other requisite action was taken) within
two (2) years prior to the date of termination of the Employee's employment.

     Notwithstanding the provisions of Sections 6(a) and 6(b), the Employee may
make passive investments in an enterprise which is competitive with AMG or the
Employer the shares or other equity interests of which are publicly traded;
PROVIDED, his holding therein together with any holdings of his Affiliates and
members of his Immediate Family, are, at the time such investments are made,
less than five percent (5%) of the outstanding shares or comparable interests in
such entity.

                  (c) The Employee, the Employer and the Company agree that the
periods of time and the unlimited geographic area applicable to the covenants of
this Section 6 and of Section 2 are reasonable, in view of the Employee's status
as a significant stockholder of the Company, which will be acquired by AMG and
which will contribute its investment advisory business to the Employer, the
Employee's receipt of a member interest in the Employer, the 

<PAGE>

Employee's receipt of the payments specified in Section 1 above, the geographic
scope and nature of the business in which the Employer is engaged, the
Employee's knowledge of the Employer's (and its predecessor, the Company's and
any predecessor thereto's) businesses and the Employee's relationships with the
Employer's and the Company's investment advisory clients. However, if such
period or such area should be adjudged unreasonable in any judicial proceeding,
then the period of time shall be reduced by such number of months or such area
shall be reduced by elimination of such portion of such area, or both, as are
deemed unreasonable, so that this covenant may be enforced in such maximum area
and during such maximum period of time as are adjudged to be reasonable.

     SECTION 7. NOTICES. All notices hereunder shall be in writing and shall be
delivered, sent by recognized overnight courier or mailed by registered or
certified mail, postage and fees prepaid, to the party to be notified at the
party's address shown below. Notices which are hand delivered or delivered by

unless and until notice of another or different address shall be given as
provided herein.

     SECTION 8. THIRD-PARTY BENEFICIARY; ASSIGNABILITY. AMG is an intended
third-party beneficiary of the provisions of this Employment Agreement. This
Employment Agreement shall be binding upon and inure to the benefit of the
Employer and the Company, and to any person or firm who may succeed to
substantially all of the assets of the Employer or the Company. This Employment
Agreement shall not be assignable by the Employee.

     SECTION 9. ENTIRE AGREEMENT. Except as set forth below, this Employment
Agreement contains the entire agreement between the Employer and the Employee
with respect to the subject matter hereof, and supersedes all prior oral and
written agreements between the Employer and the Employee with respect to the
subject matter hereof, including without limitation any oral agreements relating
to compensation. In the event of any conflict between the provisions hereof and
of the LLC Agreement, the provisions hereof shall control.

     SECTION 10. REMEDIES UPON BREACH.

     (a) In the event that the Employee breaches any of the non-competition or
non-solicitation provisions of this Employment Agreement (in each case,
including, without limitation, following the termination of his or her
employment with the LLC), then (A) the Employee shall forfeit its right to
receive any payment for its LLC Interests under Section 3.11 of the LLC
Agreement, although he or she shall cease to be a Non-Manager Member in
accordance with the provisions of Section 3.11(e) of the LLC Agreement and (B)
AMG (or its assignees) shall have no further obligations under any promissory
note theretofore issued to the Employee pursuant to Section 3.11(f) of the LLC
Agreement and (C) the Employer shall be entitled to withhold any other payments
to which the Employee otherwise would be entitled to offset damages resulting
from such breach; provided, however, that, absent a determination by an
arbitrator or a court of competent jurisdiction that the Employee has so
breached this Employment Agreement, such right of setoff shall not extend to any
payments to the Employee to the extent paid out of the Operating Allocation of
the LLC.

     (b) The Employee recognizes and agrees that the Employer or the Company's
remedy at law for any breach of the provisions of this Employment Agreement
would be inadequate and that for any breach of such provisions by the Employee,
the Employer or the Company shall, in addition to such other remedies as may be
available to it at law or in equity or 

<PAGE>

as provided in this Employment Agreement, be entitled to injunctive relief and
to enforce their respective rights by an action for specific performance to the
extent permitted by law, and to the right of setoff against any amounts due to
the Employee by the Employer or the Company. Should the Employee engage in any
activities prohibited by this Employment Agreement, he agrees to pay over to the
Employer all compensation received in connection with such activities. Such
payment shall not impair any other rights or remedies of the Employer or the
Company or affect the obligations or liabilities of the Employee under this
Employment Agreement or applicable law.

     SECTION 11. ARBITRATION OF DISPUTES. Any controversy or claim arising out
of or relating to this Employment Agreement or the breach hereof or otherwise
arising out of the Employee's employment or the termination of that employment
(including, without limitation, any claims of unlawful employment discrimination
whether based on age or otherwise) shall, to the fullest extent permitted by
law, be settled by arbitration in any forum and form agreed upon by the parties
or, in the absence of such an agreement, under the auspices of the American
Arbitration Association ("AAA") in Boston, Massachusetts in accordance with the
Employment Dispute Resolution Rules of the AAA, including, but not limited to,
the rules and procedures applicable to the selection of arbitrators, except that
the arbitrator shall apply the law as established by decisions of the U.S.
Supreme Court, the Court of Appeals for the First Circuit and the U.S. District
Court for the District of Massachusetts in deciding the merits of claims and
defenses under federal law or any state or federal antidiscrimination law, and
any awards to the Employee for violation of any antidiscrimination law shall not
exceed the maximum award to which the Employee would be entitled under the
applicable (or most analogous) federal antidiscrimination or civil rights laws.
In the event that any person or entity other than the Employee, the Employer or
the Company may be a party with regard to any such controversy or claim, such
controversy or claim shall be submitted to arbitration subject to such other
person or entity's agreement. Judgment upon the award rendered by the arbitrator
may be entered in any court having jurisdiction thereof. The parties covenant
that they will participate in the arbitration in good faith. Each party to such
arbitration shall bear its own costs and expenses in connection therewith. This
Section 11 shall be specifically enforceable. Notwithstanding the foregoing,
this Section 11 shall not preclude any party hereto from pursuing a court action
for the sole purpose of obtaining a temporary restraining order or a preliminary
injunction in circumstances in which such relief is appropriate; PROVIDED, that
any other relief shall be pursued through an arbitration proceeding pursuant to
this Section 11.

     SECTION 12. ACCELERATED PUT RIGHTS.

     (a) Notwithstanding any provisions contained in the LLC Agreement to the
contrary (including Article III and Article VII thereof), upon any exercise by
the Company of any of its rights under Section 3.2(b)(v) (a "Put Acceleration
Event"), AMG or its successors or assigns shall, upon the request of the
Employee, purchase all of the LLC Points in the LLC then held by the Employee
(or by its related Non-Manager Member, if the Employee is not itself the
Non-Manager Member) and its Permitted Transferees pursuant to the terms and
conditions of this Section 12 (an "Accelerated Put"). [In the event of such a
request by the Employee pursuant to the provisions of the preceding sentence,
the LLC shall, immediately prior to such purchase by AMG or its successors or
assigns, issue to the Employee all Program LLC Points then remaining in the
Purchase Reserve, and such Program LLC Points shall be included in the LLC
Points 

<PAGE>

purchased by AMG or its successors or assigns under this Section 12.] [Bracketed
sentence to be included only in Mr. Rorer's Employment Agreement.]

     (b) If the Employee desires to exercise his or her rights under Section
12(a), he or she shall give the Company and AMG irrevocable written notice (an
"Accelerated Put Notice") within ninety (90) days after the Put Acceleration
Event, stating that he or she is electing to sell all (but not less than all) of
the LLC Points then owned by the Employee (or by its related Non-Manager Member,
if the Employee is not itself the Non-Manager Member) and by its Permitted
Transferees.

     (c) The purchase price upon exercise of an Accelerated Put (the
"Accelerated Put Price") shall be an amount equal to (i) fourteen (14.0)
multiplied by the positive difference, if any, of (x) the sum of (I) fifty
percent (50%) of the LLC's Maintenance Fees for the twenty-four (24) months
ending on the last day of the calendar quarter in which the Put Acceleration
Event occurred and (II) thirty-three and thirty-three one-hundredths percent
(33.33%) of the LLC's Earned Performance Fees for the thirty-six (36) calendar
months ending on the last day of the calendar year prior to the calendar year in
which the Accelerated Put Event occurred, minus (y) the amount by which the
actual expenses of the LLC (determined on an accrual basis in accordance with
generally accepted accounting principles consistently applied) exceeded the
Operating Allocation of the LLC (including previously reserved Operating
Allocation) during the twelve (12) months ending on the last day of the calendar
quarter in which the Put Acceleration Event occurred, multiplied by (ii) a
fraction, the numerator of which is the number of Vested LLC Points to be
purchased from such Employee (or its related Non-Manager Member) and its
Permitted Transferees on the Accelerated Purchase Date (as defined below) and
the denominator of which is the number of LLC Points outstanding on the
Accelerated Purchase Date (before giving effect to any Puts or Accelerated Puts
or any issuances, redemptions or vesting of LLC Points on such date).

     (d) In the case of any Accelerated Put, the Accelerated Put Price shall be
paid by AMG (or its successors or assigns) on a date (the "Accelerated Purchase
Date") determined by AMG (but no later than sixty (60) days following delivery
of the Accelerated Put Notice) by wire transfer or certified check(s) issued to
the Employee (or its related Non-Manager Member) and its Permitted Transferees.

     SECTION 13. CONSENT TO JURISDICTION. To the extent that any court action is
permitted consistent with or to enforce Section 11 of this Employment Agreement,
the parties hereby consent to the jurisdiction of the Superior Court of the
Commonwealth of Massachusetts and the United States District Court for the
District of Massachusetts. Accordingly, with respect to any such court action,
the Employee (a) submits to the personal jurisdiction of such courts; (b)
consents to service of process at the address determined pursuant to the
provisions of Section 7 hereof; and (c) waives any other requirement (whether
imposed by statute, rule of court, or otherwise) with respect to personal
jurisdiction or service of process.

     SECTION 14. THIRD-PARTY AGREEMENTS AND RIGHTS. The Employee hereby confirms
that the Employee is not bound by the terms of any agreement with any previous
employer or other party which restricts in any way the Employee's use or
disclosure of information or the Employee's engagement in any business. The
Employee represents to the 

<PAGE>

Employer that the Employee's execution of this Employment Agreement, the
Employee's employment with the Employer and the performance of the Employee's
proposed duties for the Employer will not violate any obligations the Employee
may have to any such previous employer or other party. In the Employee's work
for the Employer, the Employee will not disclose or make use of any information
in violation of any agreements with or rights of any such previous employer or
other party, and the Employee will not bring to the premises of the Employer any
copies or other tangible embodiments of non-public information belonging to or
obtained from any such previous employment or other party.

     SECTION 15. LITIGATION AND REGULATORY COOPERATION. During and after the
Employee's employment, the Employee shall cooperate fully with the Employer in
the defense or prosecution of any claims or actions now in existence or which
may be brought in the future against or on behalf of the Employer or the Company
or their Affiliates which relate to events or occurrences that transpired while
the Employee was employed by the Employer (including, without limitation, its
predecessor, the Company, or any predecessor thereto). The Employee's full
cooperation in connection with such claims or actions shall include, but not be
limited to, being available to meet with counsel to prepare for discovery or
trial and to act as a witness on behalf of the Employer or the Company or their
Affiliates at mutually convenient times. During and after the Employee's
employment, the Employee also shall cooperate fully with the Employer, the
Company and their Affiliates in connection with any investigation or review of
any federal, state or local regulatory, quasi-regulatory or self-governing
authority (including, without limitation, the Securities and Exchange
Commission) as any such investigation or review relates to events or occurrences
that transpired while the Employee was employed by the Employer (including,
without limitation, its predecessor, the Company, and any predecessor thereto).
The Employer shall reimburse the Employee for any reasonable out-of-pocket
expenses incurred in connection with the Employee's performance of obligations
pursuant to this Section 15.

     SECTION 16. WAIVERS AND FURTHER AGREEMENTS. Neither this Employment
Agreement nor any term or condition hereof, including without limitation the
terms and conditions of this Section 16, may be waived or modified in whole or
in part as against the Company, the Employer or the Employee, except by written
instrument executed by or on behalf of each of the parties hereto other than the
party seeking such waiver or modification, expressly stating that it is intended
to operate as a waiver or modification of this Employment Agreement or the
applicable term or condition hereof, it being understood that any action under
this Section 16 on behalf of the Employer may be taken only with the approval of
the Company as the Manager Member of the Employer. Each of the parties hereto
agrees to execute all such further instruments and documents and to take all
such further action as the other party may reasonably require in order to
effectuate the terms and purposes of this Employment Agreement.

     SECTION 17. AMENDMENTS; EMPLOYER'S CONSENTS. This Employment Agreement may
not be amended, nor shall any change, modification, consent, or discharge be
effected except by written instrument executed by or on behalf of the party
against whom enforcement of any change, modification, consent or discharge is
sought, it being understood that any action under this Section 17 on behalf of
the Employer may be taken only with the prior written approval of the Company as
the Manager Member of the Employer.

<PAGE>

     Whenever under this Agreement the consent of the Employer is required, that
consent shall only be effective if given with the prior written consent of the
Company as the Manager Member of the Employer.

     SECTION 18. SEVERABILITY. If any provision of this Employment Agreement
shall be held or deemed to be invalid, inoperative or unenforceable in any
jurisdiction or jurisdictions, because of conflicts with any constitution,
statute, rule or public policy or for any other reason, such circumstance shall
not have the effect of rendering the provision in question unenforceable in any
other jurisdiction or in any other case or circumstance or of rendering any
other provisions herein contained unenforceable to the extent that such other
provisions are not themselves actually in conflict with such constitution,
statute or rule of public policy, but this Employment Agreement shall be
reformed and construed in any such jurisdiction or case as if such invalid,
inoperative, or unenforceable provision had never been contained herein and such
provision reformed so that it would be enforceable to the maximum extent
permitted in such jurisdiction or in such case.

     SECTION 19. GOVERNING LAW. This Employment Agreement shall be governed by
and construed and enforced in accordance with the laws of the Commonwealth of
Pennsylvania which apply to contracts executed and performed solely in the
Commonwealth of Pennsylvania.

     SECTION 20. COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same agreement.

                  IN WITNESS WHEREOF, the parties have executed this Employment
Agreement as a sealed instrument as of the date first above written.

           Affiliated Managers Group, Inc. To Make Investment in Rorer
                                Asset Management
- -------------------------------------------------------------------------------



     Boston, MA, November 9, 1998 -- Affiliated Managers Group, Inc. (NYSE: AMG)
and Rorer Asset Management ("Rorer") announced today that they have reached a
definitive agreement whereby AMG will make a significant equity investment in
Rorer.

     Rorer is a Philadelphia-based investment advisor that manages approximately
$3.7 billion for institutional clients and high net worth individuals. Founded
in 1978, Rorer specializes in investing in large and mid-cap equities and fixed
income securities, employing a highly disciplined relative value investment
process engineered by its founder, Edward C. Rorer, to reduce performance
volatility while achieving superior market returns. AMG is a Boston-based asset
management holding company which acquires majority interests in mid-sized
investment management firms while leaving a remaining substantial equity
ownership with management of the firm. AMG's strategy is to generate growth
through investments in new affiliates, as well as through the internal growth of
existing affiliated firms. Including another pending investment, AMG has 12
affiliates which had aggregate assets under management of over $53 billion at
September 30, 1998.

     William J. Nutt, AMG's Chairman, President and Chief Executive Officer
noted that, "We are extremely pleased to form a partnership with Rorer and its
outstanding management team. The successful application of their disciplined
investment process, as well as a commitment to build their business by focusing
on superior client service and back office systems and support, has led to
significant growth, through both outstanding investment results as well as by
attracting new clients."

     Mr. Rorer, Chairman and Chief Investment Officer of Rorer said, "An
affiliation with AMG allows us to remain autonomous and independent while
providing a succession plan which is in the best interests of our clients and
employees. AMG's investment structure enables us to continue to provide the
substantial incentive of equity ownership to senior management while providing
new ownership participation to a broader base of employees. The continuation of
management ownership and operating autonomy will ensure that our firm remains
focused on providing the best returns and service to our clients." James G.
Hesser, President of Rorer, added, "Due to our firm's significant growth over
the past five years, we were facing a series of important issues, ranging from
ownership succession and management continuity to adequately compensating
experienced investment professionals through equity ownership. AMG's structure
properly addresses these issues and allows us to redistribute ownership to a
succeeding generation of management."

     As a result of the transaction, Rorer will be reorganized into Rorer Asset
Management, LLC, of which AMG will own approximately a 65% interest with Rorer
management holding the remaining 35%. AMG will pay approximately $65 million in
cash for its equity position. Rorer's operations will remain unchanged and
current management will continue to oversee the operations of their firm. In
addition, certain key employees of Rorer will sign long term employment
agreements with the firm.

     Rorer Asset Management provides investment services to a diverse client
base including individuals, trusts and estates, corporations, pension and profit
sharing plans, unions and Taft-Hartley funds, and charitable institutions. The
firm offers three types of investment management accounts: large-cap equity,
balanced, and fixed income. In addition, Rorer is introducing a mid-cap equity
product employing the same relative value investment process that has been
successfully applied to large-cap equities. The Rorer approach to asset
management is a highly disciplined investment process which has provided
competitive performance results with significantly less volatility than the
market. These results are pursued by combining quantitative and qualitative
disciplines in Rorer's stock selection models and adhering to them through
market cycles.

and operations support. AMG's shareholders include TA Associates, Chase Capital,
BankAmerica, and The Hartford, as well as AMG management and the management of
