    EMPLOYMENT
AGREEMENT

     

    THIS
EMPLOYMENT AGREEMENT (this “Employment
Agreement”) is entered into as of December 12, 2009, by and among
Highbury Financial Inc., a Delaware corporation (“Highbury” or the
“General
Partner”), Manor LLC (“Manor”), a Delaware
limited liability company and a wholly-owned subsidiary of Affiliated Managers
Group, Inc., a Delaware corporation (“AMG”), Aston Asset
Management, LLC, a Delaware limited liability company (the “Employer”), and
Kenneth Anderson (the “Employee”).

     

     

    WITNESSETH:

     

    WHEREAS,
pursuant to that certain Agreement and Plan of Merger, dated as of the date
hereof (the “Merger
Agreement”), by and among AMG, Highbury and Manor, Highbury will merge
(on the terms and subject to the conditions set forth therein) with and into
Manor (with Manor surviving), at the Effective Time and, as a result AMG will
own, indirectly through Manor, which shall become the General Partner of the
Employer, a majority of the partnership interest and the associated goodwill of
the Employer (the “Merger”);

     

    WHEREAS,
the General Partner, the Employee and the other parties thereto have entered
into that certain Amended and Restated Limited Partnership Agreement of the
Employer, which will become effective as of immediately prior to the Effective
Time and reflect the conversion of the Employer into a Delaware limited
partnership by the name of Aston Asset Management, LP at such time (as the same
may be amended and/or restated from time to time, the “Restated LP
Agreement”);

     

    WHEREAS,
the Employee is a key employee of the Employer (and its predecessors thereto),
has been employed by the Employer (and its predecessors thereto) for more than
16 years, has while so employed contributed to the acquisition and retention of
Clients (as defined herein), and will continue to seek to acquire and retain
Clients and to generate goodwill in the future as an officer, employee and agent
of the Employer following the Effective Time;

     

    WHEREAS,
the General Partner, the Employer and the Employee recognize the importance of
the Employee to the Employer and to the Employer's ability to retain its client
relationships and desire that the Employer employ the Employee for the period of
employment and upon and subject to the terms herein provided;

     

    WHEREAS,
the General Partner and the Employer wish to be assured that the Employee will
not compete with the Employer or any of its Controlled Affiliates during the
period of employment and for a period thereafter, and that the Employee will not
solicit any Past Clients, Present Clients or Potential Clients of the Employer
or its Controlled Affiliates, as any such competition or solicitation by the
Employee would damage the Employer's good will among Clients and the general
public;

    
      
         

      

      
        
        

        
          

        

      

      
         

      

    

    WHEREAS,
the Employee desires to be employed by the Employer and to refrain from
competing with the Employer or any of its Controlled Affiliates or soliciting
Past Clients, Present Clients or Potential Clients for the periods and upon and
subject to the terms herein provided; and

     

    WHEREAS,
it is a condition precedent to the obligation of AMG to consummate the
transactions contemplated by the Merger Agreement and the Restated LP Agreement
that the Employee enter into and be bound by an employment agreement with the
Employer and the General Partner in the form hereof (including without
limitation the non-competition and other restrictive covenants set forth
herein).

     

    AGREEMENTS

     

    Except to
the extent otherwise expressly set forth herein, initially capitalized terms
used herein and not otherwise defined herein shall have the meaning set forth in
the Restated LP 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.  Effectiveness;
Term of Employment; Compensation; Retirement.

     

    (a)           This
Employment Agreement shall constitute a binding agreement between the parties as
of the date hereof; provided, however, that in the
event the Merger Agreement is terminated for any reason without the Effective
Time having occurred, this Employment Agreement shall be terminated without
further obligation or liability on the part of any party hereto (other than with
respect to any breaches of the terms of this Employment Agreement occurring
prior to such termination of the Merger Agreement, for which the party breaching
this Employment Agreement shall remain liable notwithstanding such termination
of the Merger Agreement).  At the Effective Time, this Employment
Agreement will supercede any then-existing employment agreement of the Employee.
Notwithstanding any other provision herein, this Employment Agreement shall
constitute a binding agreement between the parties as of the date hereof but
shall not have any force or effect until the Effective Time. Until the Effective
Time, nothing herein will be deemed to amend, modify or supersede in any respect
any other agreement the Employee may have with Employer and this Agreement shall
automatically terminate without any action by any party hereto upon the
termination of the Merger Agreement in accordance with its
terms.

    
      
         

      

      
        2

        
          

        

      

      
         

      

    

    (b)           The
Employer agrees to employ the Employee for a period of fifteen (15) years
beginning on the Closing Date (the “Term”), and the
Employee accepts such employment and agrees to be employed by the Employer for
the Term (in each case subject to termination of the Employee's employment
solely as provided herein).  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 Restated LP Agreement (including, by way of
example and not of limitation, the provisions of Section 3.5(a) of the Restated
LP 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(a) of the Restated LP Agreement, the
Employee's compensation (including salary and bonus) will be periodically
reviewed and adjusted (with respect to both increases and/or decreases). For the avoidance of
doubt, the Employee is eligible for “Retirement” (as defined in the Restated LP
Agreement) immediately following the conclusion of the Term and satisfaction of
applicable notice obligations (as more fully set forth in the Restated LP
Agreement).

operations as may from time to time be assigned to him in accordance with the
provisions of Article III of the Restated LP Agreement.  During the
Term of this Employment Agreement and thereafter while employed by the Employer,
the Employee shall devote substantially all of his working time (i.e., normal
business hours) 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

Employer, the Employee shall, solely with the prior written consent of the
Management Committee and the General Partner, be permitted to serve as a member
of the board of directors of charitable and other not for profit organizations
and private or public companies, provided that such positions do not
(individually or in the aggregate) interfere with the performance of the
Employee's duties and responsibilities hereunder, conflict with (or create the
appearance of conflict with) the businesses of the Employer and its Controlled
Affiliates, or create the appearance of significant involvement with any other
endeavor.

the contrary, the Employee agrees that his employment with the Employer shall in
no event be terminated during the Term other than solely in the following
circumstances:

a termination of such employment by the Employer For Cause, effected at any time
by (x) the General Partner, or (y) the Management Committee acting by a
Committee Vote (with such Committee Vote being calculated for all purposes as if
the Employee were not a member of the Management Committee, if he is at the time
a member of such committee) and with the prior written consent of the General
Partner;

     

    (ii) Upon
a termination of such employment by the Employer other than For Cause, effected
at any time by the Management Committee acting by a Committee Vote (with such
Committee Vote being calculated for all purposes as if the Employee were not a
member of the Management Committee, if he is at the time a member of such
committee) and with the prior written consent of the General
Partner;

     

    (iii)
Upon a termination of such employment by the Employer following the Permanent
Incapacity of the Employee, effected at any time by (i) the General Partner, or

    (iv) Upon
a termination of such employment resulting from the death of the
Employee.

     

    (b)           The
Employee agrees that, in connection with the termination (or anticipated future
termination) of his employment with the Employer for any reason, the Employee
will use reasonable best efforts to transition to other employees of the
Employer (and its Controlled Affiliates) (as determined by the Management
Committee or the General Partner) all relationships with Clients and
sub-advisers in which such Employee Equityholder has a material role (with the
intent that such relationships are transitioned to continuing employees of the
Employer (and its Controlled Affiliates) by the time of such termination and
retained following such Employee’s departure from employment), and will
cooperate in good faith with all reasonable requests of the Management Committee
and/or the General Partner in connection therewith.

     

    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 business
of the Employer and its Controlled Affiliates (or any predecessor thereto), and
all business developed by the Employer or any of its Controlled Affiliates (or
any predecessor thereto), including by the Employee or any other employee of the
Employer or any of its Controlled Affiliates (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 any of its Controlled Affiliates (or any
predecessor thereto), or earned or carried on by the Employee for the Employer
or any of its Controlled Affiliates (or any predecessor thereto), and all trade
names, service marks and logos under which the Employer or its Controlled
Affiliates (or any predecessor thereto) do or have done 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 thereof, 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 or any Controlled Affiliate thereof (or any
predecessor thereto) (the “Track Records”) was
attributable to the efforts of the team of professionals at the Employer or such
Controlled Affiliate thereof (or any predecessor thereto), and not to the
efforts of any single individual or subset of such team of professionals, and
that therefore such Track Records are and shall be the exclusive property of the
Employer or such Controlled Affiliate, as applicable (and not of the Employee or
any other Person).  In addition, the Employee acknowledges and agrees
that the Employer and its Controlled Affiliates, or any of them, as the case may
be, own and control at all times their respective customer relationships with
their Clients.  The Employee agrees that the Employee shall not, at
any time or in any way question, dispute, infringe or do any act inconsistent
with the Employer’s, or any of its Controlled Affiliates’ ownership of any of
the subject matter of this subsection.  To the extent that any rights,
title and interest, including intellectual property rights, in and to any of the
subject matter of this subsection or any part thereof become vested in the
Employee notwithstanding the provisions of this subsection by virtue of or
pursuant to any of the laws in force in any part of the world, the Employee
hereby irrevocably assigns the said rights, title and interest in such subject
matter to the Employer or its designee.

    (b)           The
Employee acknowledges and agrees that any and all intellectual property,
including software, data, compilations, designs, materials, all other
copyrightable works, inventions (whether or not patentable), and proprietary
know-how, processes, and methods, developed or created by the Employee in the
course of the Employee’s employment with the Employer (“Employee
Equityholder-Created IP”), and any and all rights therein and in any
portion thereof, shall be owned exclusively by and for the benefit of the
Employer, its Controlled Affiliates, as applicable, and their respective
successors and assigns.  To the extent any right, title and/or
interest in any Employee Equityholder-Created IP does not otherwise
automatically vest in the Employer, the Employee hereby assigns to the Employer
for good and valuable consideration, the receipt and sufficiency of which is
hereby acknowledged, all of the Employee’s entire right, title, and interest in
any Employee Equityholder-Created IP (and any portion thereof) throughout the
world, including all patent, copyright, trade secret, and other intellectual
property rights, all registration and renewal rights, all rights in works based
upon, derived from or incorporating the Employee Equityholder-Created IP, and
the right to sue, counterclaim, and recover for past, present, and future
infringement of any Employee Equityholder-Created IP.  If the Employee
has any rights in any Employee Equityholder-Created IP that cannot be assigned
to the Employer, the Employee hereby waives the enforcement of such rights,
including all moral rights and rights of attribution.

     

    (c)           The
Employee agrees to do any and all acts and execute any and all documents in such
manner and at such location as may be requested by the Employer (or its
successors or assigns) in its sole discretion, at any time during or after the
Employee’s employment with the Employer, to protect, perfect or enforce any of
the rights assigned, granted or promised to the Employer by this Employment
Agreement.

     

    (d)           The
Employee acknowledges that, in the course of performing services hereunder and
otherwise (including, without limitation, in the course of performing services
for any predecessor), 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, Track
Records, 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 (or any predecessor thereto).  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 Controlled Affiliate thereof (or any predecessor thereto) unless such
information can be shown to be in the public domain through no fault of the
Employee.  At the termination of the Employee's services to the
Employer and its Controlled Affiliates, 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.

    (e)           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 and any Controlled Affiliates thereof, the Employee will from time to
time have, access to Intellectual Property owned by or used in the course of
business by the General Partner or AMG.  The Employee agrees, for the
benefit of the Employer and its Members, and for the benefit of the General
Partner and AMG, always to keep secret and not ever publish, divulge, furnish,
use or make accessible to anyone (otherwise than at AMG's or the General
Partner'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 the General Partner or AMG) of the General Partner or AMG unless
such information can be shown to be in the public domain through no fault of the
Employee.  At the termination of the Employee's service to the
Employer and its Controlled Affiliates, 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.

     

    (f)           The
provisions of this Section 5 and of Section 6 below shall not be deemed to
limit any of the rights of the Employer or the Partners under the Restated LP
Agreement or the Employee’s Partner Non-Competition Agreement or under
applicable law, but shall be in addition to the rights set forth in the Restated
LP Agreement and the Employee’s Partner Non-Competition Agreement and those
which arise under applicable law.  The Employee acknowledges that his
obligations under this Section 5 and Section 6 of this Employment Agreement
shall survive the termination of his employment with the Employer and its
Controlled Affiliates (regardless of the manner of such
termination).  The Employee shall not enter into any agreement or
arrangement which is inconsistent with the terms and provisions of this
Employment Agreement.

     

    Section 6.  Non-Competition
and Other Restrictive Covenants as a Key Employee.

     

    (a)           The
Employee agrees, for the benefit of the Employer, the General Partner and their
respective Affiliates, that the Employee shall not, directly or indirectly
(whether individually or as owner, part owner, shareholder, partner, member,
director, officer, trustee, employee, agent, consultant or in any other

capacity, on behalf of himself or any other Person (other than the Employer or a
Controlled Affiliate thereof while employed by the Employer)), from the date of
this Agreement until two (2) years following the termination of the Employee's
employment with the Employer and all of its Controlled Affiliates for any
reason:

    (i)           Provide
Investment Management Services to any Person that is a Client (which includes
Past Clients, Present Clients and Potential Clients) for whom the Employee
provided (directly or indirectly) any Investment Management Services while

other services, or (B) causing any Client (including any Potential Client)
not to engage the Employer or any of its Controlled Affiliates to provide

    (ii)          Otherwise
divert or take away (or seek to divert or take away) any funds or investment

who are also Excluded Clients.

     

    (d)           In
addition to (and not in limitation of) the provisions of Sections 6(a), 6(b) and
6(c), the Employee agrees, for the benefit of the Employer, the General Partner
and their respective Affiliates, that the Employee shall not, directly or
indirectly (whether individually or as owner, part owner, shareholder, partner,
member, director, officer, trustee, employee, agent, consultant or in any other
capacity, on behalf of himself or any other Person (other than the Employer or a
Controlled Affiliate thereof while employed by the Employer)), from the date of
this Agreement until two (2) years following the termination of the Employee's
employment with the Employer and all of its Controlled Affiliates for any
reason:

     

    (i)
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;

     

    (ii) Hire
any employee or agent of, or consultant to, the Employer or any of its
Controlled Affiliates (or any predecessor thereto), or any person who was such
an employee, agent or consultant at any time during the two (2) year period
preceding (I) such action by the Employee (in the case of any such action taken
by the Employee while he remains employed by the Employer or any of its
Controlled Affiliates) or (II) the termination of the Employee's employment with
the Employer and its Controlled Affiliates (in the case of any such action taken
by the Employee following termination of his employment); or

     

    (iii)         Work
in any enterprise involving Investment Management Services with any employee,
agent or consultant or former employee, agent or consultant, of the Employer or
any of its Controlled Affiliates (or any predecessor thereto) who was employed
by or acted as an agent or consultant to the Employer or any of its Controlled
Affiliates (or any predecessor thereto) at any time during the two (2) year
period preceding (I) such action by the Employee (in the case of any such action
taken by the Employee while he remains employed by the Employer or any of its
Controlled Affiliates) or (II) the termination of the Employee's employment with
the Employer and its Controlled Affiliates (in the case of any such action taken
by the Employee following termination of his employment);

     

    (but
excluding, for all purposes of this sentence, secretaries and persons holding
other similar ministerial positions).

     

    (e)           Notwithstanding
the provisions of Sections 6(a), 6(b), 6(c) and 6(d), the Employee shall
not be prohibited (following the termination of the Employee's employment with
the Employer and its Controlled Affiliates) from serving as an independent
trustee on the board of trustees of an investment company registered under the
1940 Act.

    (f)           Notwithstanding
the provisions of Sections 6(a), 6(b), 6(c) and 6(d), the Employee may make
passive personal investments in an enterprise (whether or not 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 and their Affiliates, are less than five percent (5%) of
the outstanding shares or comparable interests in such entity.

     

    (g)           The
Employee, the Employer and the General Partner agree that (x) the
non-competition and other restrictive covenants set forth in this Section 6 have
been entered into by the Employee in recognition of (and in connection with) his
capacity as a key employee of the Employer (and its predecessors), and as a
condition precedent to the obligation of AMG to consummate the transactions
contemplated by the Merger Agreement and the Restated LP Agreement, and (y) the
periods of time and the unlimited geographic area applicable to the covenants
set forth in this Section 6 (and all other aspects of the scope of such
covenants) are reasonable in view of (without limitation):

     

    (i)           The
geographic scope and nature of the businesses in which the Employer and its
Controlled Affiliates are (or any predecessors thereto were)
engaged;

     

    (ii)          The
Employee's role as a key employee of the Employer (and its
predecessors);

     

    (iii)         The
Employee’s status as a limited partner of the Employer (directly and/or through
his related Limited Partner, as applicable), and his fiduciary and other duties
in connection therewith;

     

    (iv)         The
Employee's receipt of the payments described in Section 1(b) above;

     

    (v)          The
Employee's knowledge of the Employer's and its Controlled Affiliates’ (and any
predecessors’) businesses and the confidential and proprietary information
thereof, including without limitation as a key employee thereof;
and

     

    (vi)         The
Employee's relationships with the Employer's and its Controlled Affiliates’ (and
any predecessors’) Clients, including without limitation as a key employee of
their businesses.

     

    However,
the parties hereto agree that, if any such period of time or geographic area (or
other aspect of the scope of such covenants) should be adjudged unreasonable in
any judicial or arbitral proceeding, then such period of time shall be reduced
by such number of months, or such geographic area shall be reduced by
elimination of such portion of such area, or such other aspect of the scope of
such covenants shall be reduced in respect of such portion thereof (as
applicable), in any such case as is deemed unreasonable, such that such
covenants may be enforced during such maximum period of time, in such maximum
geographic area, and with such maximum scope, as is adjudged to be
reasonable.

    (h)           The
Employee agrees (on behalf of himself, his agents, and other parties under his
control or influence) while he is employed by the Employer and thereafter not to
make any communication to any third party (including, by way of example and not
of limitation, any Client (including Potential Clients) or employee of the
Employer, AMG or any Affiliate of AMG) which would, or is reasonably likely to,
disparage, create a negative impression of, or in any way be harmful to the
business or business reputation of the Employer, AMG, any of AMG's Affiliates,
or their respective successors and assigns, or any of the then-current or former
officers, directors, partners, members or employees of any of the
foregoing.

     

    (i)           The
Employee acknowledges and agrees that the restrictive covenants and other
agreements of the Employee contained in this Employment Agreement are an
essential part of this Employment Agreement.  The Employee further
represents, warrants and agrees that the Employee has been fully advised by, or
has had the opportunity to be fully advised by, counsel in connection with the
negotiation, preparation, execution and delivery of this Employment Agreement
and the transactions contemplated by this Employment Agreement and the other
Transaction Documents (as defined in the Merger
Agreement).  Accordingly, the Employee agrees to be bound by the
restrictive covenants and other agreements of the Employee contained in this
Employment Agreement, it being the intent and spirit of the parties that the
restrictive covenants and other agreements of the Employee contained in this
Employment Agreement shall be valid and enforceable in all
respects.

    Section 8. Third-Party Beneficiary;
Assignability.  AMG is an intended third-party beneficiary of
the provisions of this Employment Agreement.  This Employment
Agreement may be assigned by the Employer, AMG and/or the General Partner
without the consent of the Employee (but in the case of the Employer, only to
one or more successors to all or substantially all of the business of the
Employer).  This Employment Agreement shall be binding upon and inure
to the benefit of the Employer, the General Partner and their successors and
permitted assigns.  This Employment Agreement shall not be assignable
by the Employee.  For the avoidance of doubt, the General Partner as a
party hereto shall be deemed to be a direct beneficiary of each of the covenants
and agreements of the Employee hereunder, and the General Partner shall be
entitled to enforce all such covenants and agreements on its own
behalf.

     

    Section 9.  Entire
Agreement.  This Employment Agreement, together with the other
Transaction Documents (as defined in the Merger Agreement), contain the entire
agreement among the parties hereto with respect to the subject matter hereof,
and supersede all prior oral or written agreements between the Employer or any
Controlled Affiliate thereof (or any predecessor thereto) 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 Restated LP Agreement, the provisions
hereof shall control.

     

    Section 10.  Remedies Upon
Breach.

     

    (a)           In
the event that the Employee breaches any of the provisions of this Employment
Agreement (or otherwise violates any of the stated terms of such provisions),
including without limitation following the termination of the Employee's
employment with the Employer and its Controlled Affiliates, then in such event,
in addition to (and not in limitation of) such other remedies as the Employer
and the General Partner may have against the Employee:

     

    (i)           The
Employee and any related Limited Partners thereof shall forfeit their right to
receive any payment for their Partnership Points under the Restated LP
Agreement, although they shall cease to be Limited Partners in accordance with
the provisions of the Restated LP Agreement;

    
      
         

      

      
        14

        
          

        

      

      
         

      

    

    (ii)          Neither
AMG nor the General Partner (or any of its assignees under the Restated LP
Agreement) shall have any further obligations under any Promissory Note or
Liquidation Date Consideration issued to the Employee or any related Limited
Partner thereof pursuant to the provisions of the Restated LP Agreement;
and

     

    (iii)         The
Employer shall be entitled to (and, at the direction of the General Partner,
shall), and the General Partner and its Affiliates shall be entitled to, in each
such case withhold and cancel any other payments to which the Employee or any
related Limited Partner or other Affiliate thereof otherwise would be entitled
(whether pursuant to this Agreement or any other agreement, plan or policy) to
offset damages resulting from such breach.

     

    The
Employee agrees that the remedies provided in this Section 10(a) with respect to
breaches (or other violations) of the provisions of this Employment Agreement
are reasonably related to anticipated losses that the Employer and the General
Partner would suffer upon a breach (or other violation) of such provisions by
the Employee.

     

    (b)           The
Employee recognizes and agrees that the Employer and the General Partner's
remedies at law for any breach (or other violation), or threatened breach (or
other violation), of the provisions of this Employment Agreement would be
inadequate, and that for any breach or threatened breach (or other violation) of
such provisions by the Employee, the Employer and the General Partner shall, in
addition to such other remedies as may be available to them at law or in equity
or as provided in this Employment Agreement, each be entitled to injunctive
relief and enforcement of their respective rights by an action for specific
performance to the extent permitted by law (and without having to post bond),
and to an award of attorney’s fees and costs incurred in connection with
securing any of their rights hereunder.  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 General Partner or affect the obligations or
liabilities of the Employee under this Employment Agreement or any other written
agreement to which he is a party or under applicable law.

     

    Section 11.   Dispute
Resolution.  Any controversy, claim or dispute 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 binding arbitration in accordance with the provisions of
Section 10.6 of the Restated LP Agreement.

    Section 12. Consent to
Jurisdiction.  For the purposes of any judicial proceedings
ancillary to an arbitration under Section 11 of this Agreement, each of the
parties hereto hereby consents to personal jurisdiction, service of process and
venue in the federal and state courts sitting in Illinois and hereby irrevocably
agrees that any such judicial proceedings may be heard and determined in any
such state court or, to the extent permitted by law, in such federal
court.  Each of the parties hereto hereby irrevocably consents to the
service of process in any such proceedings 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 7
hereof.  The parties hereto agree that a final judgment in any such
proceedings shall be conclusive and may be enforced in other jurisdictions by
suit or in any other manner permitted by law, and nothing contained herein shall
affect the right of a party to service legal process or to bring any action or
proceeding in the courts of other jurisdictions (subject to the provisions of
Section 11 hereof).

     

    Section 13. Third-Party Agreements
and Rights.

     

    (a)           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 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 employer or other party.

     

    (b)           The
Employee agrees to provide written notice of the provisions of Section 6 of this
Agreement (and shall provide a copy of such notice concurrently to the Employer
and the General Partner), together with a copy thereof, to any enterprise
engaged in whole or in part in the provision of Investment Management Services
for which the Employee acts as an employee or otherwise becomes associated
following his termination of employment with the Employer (prior to acting in
such capacity or commencing such association, as applicable).

     

    Section 14.  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 General Partner or
their Affiliates which relate to events or occurrences that transpired while the
Employee was employed by the Employer (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 General Partner or their Affiliates at mutually
convenient times.  During and after the Employee's employment, the
Employee also shall cooperate fully with the Employer, the General Partner 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 (or 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 14.

    Section 15.  Waivers and
Further Agreements.  Neither this Employment Agreement nor any
term or condition hereof, including without limitation the terms and conditions
of this Section 15, may be waived or modified in whole or in part as against the
General Partner, 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, provided that any action under this Section
15 on behalf of the Employer may be taken only with the prior written approval
of the General Partner (as the general partner 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 16.  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, provided that any
action under this Section 16 on behalf of the Employer may be taken only with
the prior written approval of the General Partner (as the general partner of the
Employer).  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 General Partner (as the general partner of the
Employer).

     

    Section
17.  Severability.  If any provision of this
Employment Agreement shall be adjudged in any judicial or arbitral proceeding 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,
and 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.  Moreover, if any one or more of the provisions contained in
this Employment Agreement shall be adjudged in any judicial or arbitral
proceeding to be excessively broad as to duration, activity or subject (or in
any other respect), such provisions shall be construed by limiting and reducing
them so as to be enforceable to the maximum extent allowed by applicable
law.  For the avoidance of doubt, the provisions of this Employment
Agreement are severable, and no breach of any provision of this Employment
Agreement (or any other Transaction Document, as defined in the Merger
Agreement) or any other purported violation of law by the Employer or the
General Partner shall operate to excuse the Employee’s obligation to fulfill his
covenants and agreements hereunder (including without limitation the
requirements of Sections 5 and 6 hereof).  For the further avoidance
of doubt, the Employee understands that his employment with the Employer is
subject to material changes (including without limitation in respect of the
nature of his duties and/or compensation), and he agrees that no such changes
shall operate to extinguish any of his obligations under this Employment
Agreement or to require the re-signing of this Employment
Agreement.

    Section 18.  Governing
Law.  This Employment Agreement shall be governed by and
construed and enforced in accordance with the laws of Illinois which apply to
contracts executed and performed solely in Illinois, and without regard to any
rule or canon of construction which interprets agreements against the drafting

    PARTNER
NON-COMPETITION AGREEMENT

     

    THIS
PARTNER NON-COMPETITION AGREEMENT (this “Agreement”) is
entered into as of December 12, 2009, by and among Highbury Financial Inc., a
Delaware corporation (“Highbury” or the
“General
Partner”), Manor LLC (“Manor”), a Delaware
limited liability company and a wholly-owned subsidiary of Affiliated Managers
Group, Inc., a Delaware corporation (“AMG”), Aston Asset
Management, LLC, a Delaware limited liability company (the “Employer”), and
Stuart Bilton (the “Equityholder”).

     

    WHEREAS,
the Employer is engaged in the business of providing Investment Management
Services;

     

    WHEREAS,
pursuant to an Agreement and Plan of Merger, dated as of the date hereof (the
“Merger
Agreement”), by and among AMG, Highbury and Manor, Highbury will merge
(on the terms and subject to the conditions set forth therein) with and into
Manor (with Manor surviving), at the Effective Time and, as a result, AMG will
own, indirectly through Manor, a majority of the partnership interest and the
associated goodwill of the Employer (the “Merger”) and, at the
Effective Time, AMG will pay significant consideration to the equityholders of
Highbury (the “Merger
Consideration”);

     

    WHEREAS,
simultaneously with the execution of the Merger Agreement, the Equityholder has
become a party to that certain Amended and Restated Limited Partnership
Agreement of the Employer (as the same may be amended and/or restated from time
to time, the “Restated
LP Agreement”), which will become effective immediately prior to the
Effective Time and reflect the conversion of the Employer into a Delaware
limited partnership by the name of Aston Asset Management, LP at such time, and
pursuant to which Manor will become the General Partner of the Employer, and the
Equityholder will continue to hold (directly and/or through his related Limited
Partner (as defined in the Restated LP Agreement), if any) an equity interest in
the business of the Employer through his Retained Ownership Interest (as defined
in the Merger Agreement) therein;

     

    WHEREAS,
as a significant owner of the Employer, the Equityholder will receive
substantial economic and other benefits in his ownership capacity if the Merger
is consummated, including his receipt on the Closing Date of significant
consideration;

     

    WHEREAS,
the Equityholder also will continue to own a substantial equity interest in the
business of the Employer following consummation of the Merger, and the
Equityholder will have the opportunity in the future to receive additional
substantial payments from the General Partner pursuant to the Equityholder's
sale of his Retained Ownership Interest in the Employer to the General Partner
under the Restated LP Agreement;

     

    WHEREAS,
the Equityholder has been an owner of the business of the Employer (and its
predecessors) for more than thirty-eight (38) years, has during such time
contributed to the acquisition and retention of Clients (as defined herein), and
will continue to seek to acquire and retain Clients and to generate goodwill in
the future as a partner of the Employer following the Closing;

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    WHEREAS,
the General Partner, the Employer and the Equityholder recognize the importance
of the Equityholder to the Employer and to the Employer's ability to retain its
Client relationships and generate goodwill in the future;

     

    WHEREAS,
the General Partner and the Employer wish to be assured that the Equityholder
will not, while a partner of the Employer and for a period thereafter, compete
with the Employer or any of its Controlled Affiliates or solicit any Past
Clients, Present Clients, or Potential Clients (each as defined herein) of the
Employer or its Controlled Affiliates, as any such competition or solicitation
by the Equityholder would damage the Employer's goodwill among its Clients and
the general public;

     

    WHEREAS,
in connection with the Equityholder's sale in the Merger and his retention
(directly and/or through his related Limited Partner, if any) of his Retained
Ownership Interest following the consummation thereof, the Equityholder agrees
to refrain from competing with the Employer or any of its Controlled Affiliates
or soliciting Past Clients, Present Clients or Potential Clients for the
periods, and upon and subject to the terms, provided herein; and

     

    WHEREAS,
it is a condition precedent to the obligation of AMG to consummate the
transactions contemplated by the Merger Agreement and the Restated LP Agreement
(including without limitation the Equityholder's receipt of consideration in
connection with the Merger, the Equityholder's retention of his Retained
Ownership Interests and the Equityholder's opportunity to receive substantial
additional payments in the future upon the sale of those Retained Ownership
Interests to the General Partner under the Restated LP Agreement) that the
Equityholder enter into and be bound by this Agreement.

obligation or liability on the part of any party
hereto.  Notwithstanding any other provision herein, this Agreement
shall constitute a binding agreement between the parties as of the date hereof
but shall not have any force or effect until the Effective Time. Until the
Effective Time, nothing herein will be deemed to amend, modify or
supersede in any respect any other agreement the Employee may have with
Employer and this Agreement shall automatically terminate without any action by
any party hereto upon the termination of the Merger Agreement in accordance with
its terms.

Agreement.

with respect to which the Employer or any of its Controlled Affiliates provides
Investment Management Services to be withdrawn from such management or other
services, or (B) causing any Client (including any Potential Client) not to
engage the Employer or any of its Controlled Affiliates to provide Investment
Management Services for any additional funds or accounts (or otherwise attempt
to cause any of the foregoing to occur);

     

    (ii)          Otherwise
divert or take away (or seek to divert or take away) any funds or investment
accounts with respect to which the Employer or any of its Controlled Affiliates
provides Investment Management Services; or

     

    (iii)         Contact
or communicate with, whether directly or indirectly, any Past Clients, Present
Clients or Potential Clients in connection with providing Investment Management
Services to such Persons;

     

    provided, however, that this
Section 3(c) shall not be applicable to Clients (including Potential Clients)
who are also Excluded Clients.

    

    (d)  
   In addition to, and not in limitation of, the provisions of
Sections 3(a), 3(b) and 3(c), the Equityholder agrees, for the benefit of the
Employer, the General Partner and their respective Affiliates, that the
Equityholder shall not, directly or indirectly (whether individually or 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 other Person (other than the Employer and its Controlled Affiliate thereof
while a Partner (directly and/or through his related Limited Partner, as
applicable) of the Employer), during the period beginning on the Closing Date
and until the sixth (6th) anniversary of the
Closing Date (for the avoidance of doubt, whether or not the Equityholder has
ceased to be a Partner of the Employer (directly and/or through his related
Limited Partner, as applicable) for any reason):

     

    (i)         
  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;

    
    

     

    (ii)           Hire
any employee or agent of, or consultant to, the Employer or any of its
Controlled Affiliates (or any predecessor thereto), or any person who was such
an employee, agent or consultant at any time during the two (2) year period
preceding (I) such action by the Equityholder (in the case of any such action
taken by the Equityholder while he remains a Partner of the Employer (directly
and/or through his related Limited Partner, as applicable)) or (II) the
termination of the Equityholder's status (directly and/or through his related
Limited Partner, as applicable) as a Partner of the Employer (in the case of any
such action taken by the Equityholder following termination of such status);
or

     

    
      
        
        

      

      
        7

        
          

        

      

      
        
        

      

    

     

    (iii)          Work
in any enterprise involving Investment Management Services with any employee,
agent or consultant or former employee, agent or consultant, of the Employer or
any of its Controlled Affiliates (or any predecessor thereto) who was employed
by or acted as an agent or consultant to the Employer or any of its Controlled
Affiliates (or any predecessor thereto) at any time during the two (2) year
period preceding (I) such action by the Equityholder (in the case of any such
action taken by the Equityholder while he remains a Partner of the Employer
(directly and/or through his related Limited Partner, as applicable)) or (II)
the termination of the Equityholder's status (directly and/or through his
related Limited Partner, as applicable) as a Partner of the Employer (in the
case of any such action taken by the Equityholder following termination of such
status);

     

    (but
excluding, for all purposes of this sentence, secretaries and persons holding
other similar ministerial positions).

    

    (e)   
  Notwithstanding the provisions of Sections 3(a), 3(b), 3(c) and
3(d), the Equityholder may make passive personal investments in an enterprise
(whether or not competitive with AMG or the Employer) the shares or other equity
interests of which are publicly traded, provided that his holding
therein, together with any holdings of his Affiliates and members of his
Immediate Family and their Affiliates, are less than five percent (5%) of the
outstanding shares or comparable interests in such entity.

     

    (f)  
    The Equityholder, the Employer and the General Partner
agree that (x) the non-competition and other restrictive covenants set forth in
this Section 3 have been entered into by the Equityholder in connection with the
Merger and in recognition of (and in connection with) his direct and indirect
ownership of the business of the Employer (and its predecessors thereto), his
status (directly and/or through his related Limited Partner, as applicable) as a
Partner of the Employer following consummation of the Merger, and as a condition
precedent to the obligation of AMG to consummate the transactions contemplated
by the Merger Agreement and the Restated LP Agreement, and (y) the periods of
time and the unlimited geographic area applicable to the covenants set forth in
this Section 3 (and all other aspects of the scope of such covenants) are
reasonable in view of (without limitation):

     

    (i)           The
Equityholder's ownership in the business of the Employer (and its predecessors)
for more than thirty-eight (38) years and his status as a significant
equityholder of the Holding Company, the businesses of which are being acquired
in the Merger;

     

    (ii)          The
Equityholder's receipt of significant consideration in connection with the
Merger, including the sale of the goodwill inherent in the Holding Company’s and
its Controlled Affiliates’ (including without limitation the Employer’s (and its
predecessors’) and its Controlled Affiliates’) relationships with Clients
resulting therefrom;

     

    
      
        
        

      

      
        8

        
          

        

      

      
        
        

      

    

     

    (iii)         The
Equityholder's retention of a significant ownership interest in the business of
the Employer following consummation of the Merger (directly and/or through his
related Limited Partner, as applicable), and his status as a Partner of the
Employer in connection with his Retained Ownership Interest
therein;

     

    (iv)        
The Equityholder's opportunity in the future to receive substantial additional
payments from the General Partner (directly and/or through his related Limited
Partner, as applicable) pursuant to the Equityholder's sale of his Retained
Ownership Interest to the General Partner under the Restated LP Agreement, which
the Equityholder, the General Partner and the Employer acknowledge provides the
Equityholder with an additional future opportunity to be a seller of the
goodwill of the Employer represented by such Retained Ownership Interest, and
constitutes a separate and independent reason that the periods of time and scope
of the covenants set forth in this Section 3 are reasonable;

     

    (v)          The
geographic scope and nature of the businesses in which the Employer and its
Controlled Affiliates are (and their predecessors were) engaged;

     

    (vi)         The
Equityholder's knowledge of the Employer's and its Controlled Affiliates’ (and
their predecessors’) businesses and the confidential and proprietary information
thereof, including without limitation as an owner thereof;

     

    (vii)        The
Equityholder’s status as a partner of the Employer (directly and/or through his
related Limited Partner, as applicable), and his fiduciary and other duties in
connection therewith; and

     

    (viii)       The
Equityholder’s relationships with the Employer’s (and its predecessors’)
Clients, including without limitation as an owner of the Employer and its
predecessor.

     

    However,
the parties hereto agree that, if any such period of time or geographic area (or
other aspect of the scope of such covenants) should be adjudged unreasonable in
any judicial or arbitral proceeding, then such period of time shall be reduced
by such number of months, or such geographic area shall be reduced by
elimination of such portion of such area, or such other aspect of the scope of
such covenants shall be reduced in respect of such portion thereof (as
applicable), in any such case as is deemed unreasonable, such that such
covenants may be enforced during such maximum period of time, in such maximum
geographic area, and with such maximum scope, as is adjudged to be
reasonable.

    (g)
     The Equityholder agrees to provide written
notice of the provisions of this Section 3 (and shall provide a copy of such
notice concurrently to the Employer and the General Partner), together with a
copy thereof, to any enterprise engaged in whole or in part in the provision of
Investment Management Services for which the Equityholder acts as an employee or
otherwise becomes associated following termination of his status (directly
and/or through his related Limited Partner, as applicable) as a Partner of the
Employer (prior to acting in such capacity or commencing such association, as
applicable).

     

    
      
        
        

      

      
        9

        
          

        

      

      
        
        

      

    

     

    (h) 
    The provisions of this Section 3 shall not be deemed to
limit any of the rights of the Employer or the Partners under the Restated LP
Agreement, the Equityholder's Employment Agreement or under applicable law, but
shall be in addition to the rights set forth in the Restated LP Agreement and
the Equityholder's Employment Agreement and those which arise under applicable
law.

     

    (i)   
   The Equityholder acknowledges and agrees that the restrictive
covenants and other agreements of the Equityholder contained in this Agreement
are an essential part of this Agreement.  The Equityholder further
represents, warrants and agrees that the Equityholder has been fully advised by,
or has had the opportunity to be fully advised by, counsel in connection with
the negotiation, preparation, execution and delivery of this Agreement and the
transactions contemplated by this Agreement and the other Transaction
Documents.  Accordingly, the Equityholder agrees to be bound by the
restrictive covenants and other agreements of the Equityholder contained in this
Agreement, it being the intent and spirit of the parties that such restrictive
covenants and other agreements of the Equityholder contained in this Agreement
shall be valid and enforceable in all respects.

     

    4.           Absence of Conflicting
Agreements.  The Equityholder represents that he is not bound
by any agreement or any other existing or previous business relationship which
conflicts with or prevents the full performance of his duties and obligations
under this Agreement or otherwise (including, without limitation, his duties as
a Partner of the Employer (directly and/or through his related Limited Partner,
as applicable)).  In addition, the Equityholder represents that he is
not a party to or bound by any agreement with any business or venture competing
with the Employer (or its predecessor), AMG, the General Partner or their
respective Controlled Affiliates (except to the extent the Employer and its
Controlled Affiliates compete with other of AMG's Controlled Affiliates), and
covenants that he will not enter into or discuss entering into any such
agreement while a Partner of the Employer (directly and/or through his related
Limited Partner, as applicable).

     

    5.           Remedies Upon
Breach.

     

    (a)  
   In the event that the Equityholder breaches any of the
provisions of this Agreement (or otherwise violates any of the stated terms of
such provisions), including without limitation following the termination of the
Equityholder's status as a Partner of the Employer (directly and/or through his
related Limited Partner, as applicable), then in such event, in addition to (and
not in limitation of) such other remedies as the Employer and the General
Partner may have against the Equityholder:

     

    (i)           The
Equityholder and any related Limited Partners thereof shall forfeit their right
to receive any payment for their Partnership Points under the Restated LP
Agreement, although they shall cease to be Limited Partners in accordance with
the provisions of the Restated LP Agreement;

     

    
      
        
        

      

      
        10

        
          

        

      

      
        
        

      

    

     

    (ii)           Neither
AMG nor the General Partner (or any of their assignees under the Restated LP
Agreement) shall have any further obligations under any Promissory Note or
Liquidation Date Consideration issued to the Equityholder or any related Limited
Partner thereof pursuant to the Restated LP Agreement; and

     

    (iii)          The
Employer shall be entitled to (and, at the direction of the General Partner,
shall), and the General Partner and its Affiliates shall be entitled to, in each
such case withhold and cancel any other payments to which the Equityholder or
any related Limited Partner or other Affiliate thereof otherwise would be
entitled (whether pursuant to this Agreement or any other agreement, plan or
policy) to offset damages resulting from such breach.

     

    The
Equityholder agrees that the remedies provided in this Section 5(a) with respect
to breaches (or other violations) of the provisions of this Agreement are
reasonably related to anticipated losses that the Employer and the General
Partner would suffer upon a breach (or other violation) of such provisions by
the Equityholder.

    

    (b)  
   The Equityholder recognizes and agrees that the Employer's and
the General Partner's remedies at law for any breach (or other violation), or
threatened breach (or other violation), of the provisions of this Agreement
would be inadequate, and that for any breach or threatened breach (or other
violation) of such provisions by the Equityholder, the Employer and the General
Partner shall, in addition to such other remedies as may be available to them at
law or in equity or as provided in this Agreement, each be entitled to
injunctive relief and enforcement of their respective rights by an action for
specific performance to the extent permitted by law (and without having to post
bond), and to an award of attorney's fees and costs incurred in connection with
securing any of their rights hereunder.  Should the Equityholder
engage in any activities prohibited by this 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 General Partner or affect the obligations or
liabilities of the Equityholder under this Agreement or any other written
agreement to which he is a party or under applicable law.

     

    6.           Miscellaneous.  The
Equityholder acknowledges that his obligations under this Agreement shall
survive the termination of the Equityholder's status (directly and/or through
his related Limited Partner, as applicable) as a Partner of the Employer
(regardless of the manner of such termination).  The Equityholder
shall not enter into any agreement or arrangement which is inconsistent with the
terms and provisions of this Agreement.

     

    
    

    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 recognized
overnight courier shall be effective on delivery.  Notices which are
mailed shall be effective on the third day after mailing.

    8.           Third-Party Beneficiary;
Assignability.  AMG is an intended third-party beneficiary of
the provisions of this Agreement.  This Agreement may be assigned by
the Employer, AMG and/or the General Partner without the consent of the
Equityholder (but in the case of the Employer, only to one or more successors to
all or substantially all of the business of the Employer).  This
Agreement shall be binding upon and inure to the benefit of the Employer, the
General Partner and their successors and permitted assigns. This Agreement shall
not be assignable by the Equityholder.  For the avoidance of doubt,
the General Partner as a party hereto shall be deemed to be a direct beneficiary
of each of the covenants and agreements of the Equityholder hereunder, and the
General Partner shall be entitled to enforce all such covenants and agreements
on its own behalf.

     

    
      
        
        

      

      
        12

        
          

        

      

      
        
        

      

    

    9.           Entire
Agreement.  This Agreement, together with the other Transaction
Documents, contain the entire agreement among the parties hereto with respect to
the subject matter hereof, and supersede all prior oral or written agreements
between the Employer or any Controlled Affiliate thereof (any predecessor
thereto or any Controlled Affiliate thereof) and the Equityholder with respect
to the subject matter hereof.  In the event of any conflict between
the provisions hereof and of the Restated LP Agreement, the provisions hereof
shall control.

     

    10.         Dispute
Resolution.  All disputes arising under or in connection with
this Agreement shall be settled by binding arbitration in accordance with the
provisions of Section 10.6 of the Restated LP Agreement.

     

    11.         Consent to
Jurisdiction.  For the purposes of any judicial proceedings
ancillary to an arbitration under Section 10 of this Agreement, each of the
parties hereto hereby consents to personal jurisdiction, service of process and
venue in the federal and state courts sitting in Illinois and hereby irrevocably
agrees that any such judicial proceedings may be heard and determined in any
such state court or, to the extent permitted by law, in such federal
court.  Each of the parties hereto hereby irrevocably consents to the
service of process in any such proceedings 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 7
hereof.  The parties hereto agree that a final judgment in any such
proceedings shall be conclusive and may be enforced in other jurisdictions by
suit or in any other manner permitted by law, and nothing contained herein shall
affect the right of a party to service legal process or to bring any action or
proceeding in the courts of other jurisdictions (subject to the provisions of
Section 10 hereof).

     

    12.         Waivers and Further
Agreements.  Neither this Agreement nor any term or condition
hereof, including without limitation the terms and conditions of this Section
12, may be waived or modified in whole or in part as against the General
Partner, the Employer or the Equityholder, 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 Agreement or the applicable term or condition
hereof, provided that any
action under this Section 12 on behalf of the Employer may be taken only with
the prior written approval of the General Partner (as the general partner 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 Agreement.

     

    13.         Amendments; Employer's
Consent.  This 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, provided that any
action under this Section 13 on behalf of the Employer may be taken only with
the prior written approval of the General Partner (as the general partner of the
Employer).  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 General Partner (as the general partner of the
Employer).

     

    
      
        
        

      

      
        13

        
          

        

      

      
        
        

      

    

     

    14.         Severability. If any
provision of this Agreement shall be adjudged in any judicial or arbitral
proceeding 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, and this 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.  Moreover, if any one or more of the
provisions contained in this Agreement shall be adjudged in any judicial or
arbitral proceeding to be excessively broad as to duration, activity or subject
(or in any other respect), such provisions shall be construed by limiting and
reducing them so as to be enforceable to the maximum extent allowed by
applicable law.  For the avoidance of doubt, the provisions of this
Agreement are severable, and no breach of any provision of this Agreement (or
any other Transaction Document) or any other purported violation of law by the
Employer or the General Partner shall operate to excuse the Equityholder's
obligation to fulfill his covenants and agreements hereunder (including without
limitation the requirements of Section 3 hereof).  For the further
avoidance of doubt, the Equityholder understands that his relationship with the
Employer is subject to material changes (including without limitation in respect
of the nature of his duties and/or compensation), and he agrees that no such
changes shall operate to extinguish any of his obligations under this Agreement
or to require the re-signing of this Agreement.

     

    15.         Governing
Law.  This Agreement shall be governed by and construed and
enforced in accordance with the laws of Illinois which apply to contracts
executed and performed solely in Illinois, and without regard to any rule or
canon of construction which interprets agreements against the drafting
party.

     

    16.         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.  Signatures delivered by facsimile or electronic PDF file
shall constitute original signatures.
