such additional times as the Company may reasonably request such code
as set forth in the Company's "Professional Conduct
Manual" or other applicable manual or handbook of the
Company or any of its subsidiaries as in effect from time to time.
Notwithstanding the foregoing, the Senior Advisor agrees to execute
such code to the extent the provisions therein are not inconsistent
with the provisions of this Agreement.

SECTION
10.    Confidential Information.    The Senior Advisor
will not at any time (whether during or after the Employment Term)
disclose or use for the Senior Advisor's own benefit or purposes
or the benefit or purposes of any other person, firm, partnership,
joint venture, association, corporation or other business organization,
entity or enterprise other than the Company and any of its subsidiaries
or affiliates, any trade secrets, information, data, or other
confidential or proprietary information relating to customers,
development programs, costs, marketing, trading, investment, sales
activities, promotion, credit and financial data, financing methods,
plans, or the business and affairs of the Company generally, or of any
subsidiary or affiliate of the Company, provided that the
foregoing shall not apply to information which is not unique to the
Company or which is generally known to the industry or the public other
than as a result of the Senior Advisor's breach of this covenant.
The Senior Advisor agrees that upon termination of the Employment Term
for any reason, the Senior Advisor or, in the event of the Senior
Advisor's death, the Senior Advisor's heirs or estate at
the request of the Company, will return to the Company immediately all
memoranda, books, papers, 

34

plans, information, letters and other data,
and all copies thereof or therefrom, in any way relating to the
business of the Company and its affiliates, except that the Senior
Advisor (or the Senior Advisor's heirs or estate) may retain
personal notes, notebooks and diaries. The Senior Advisor further
agrees that the Senior Advisor will not retain or use for the Senior
Advisor's account at any time any trade names, trademark or other
proprietary business designation used or owned in connection with the
business of the Company or its affiliates.

SECTION
11.    Non-competition.

(a) The Senior Advisor
acknowledges and recognizes the highly competitive nature of the
businesses of the Company and its affiliates. The Senior Advisor
further acknowledges and agrees that in the course of the Senior
Advisor's subsequent employment with the Company or its
affiliates, the Senior Advisor has been and will be provided with
access to sensitive and proprietary information about the clients,
prospective clients, knowledge capital and business practices of the
Company or its affiliates, and has been and will be provided with the
opportunity to develop relationships with clients, prospective clients,
consultants, employees, representatives and other agents of the Company
or its affiliates, and the Senior Advisor further acknowledges that
such proprietary information and relationships are extremely valuable
assets in which the Company or its affiliates or any of their
predecessors have invested and will continue to invest substantial
time, effort and expense. Accordingly, the Senior Advisor agrees that
during the Employment Term, the Senior Advisor shall not, directly or
indirectly, on the Senior Advisor's behalf or on behalf of any
other person, firm, corporation, association or other entity, as an
employee or otherwise, engage in, or in any way be concerned with or
negotiate for, or acquire or maintain any ownership interest in, a
Competitive Enterprise. For purposes of this Agreement,
"Competitive Enterprise" shall mean a
business (or business unit) that (i) engages in any activity or (ii)
owns or controls a significant interest in any entity that engages in
any activity, that in either case, competes anywhere with any activity
in which the Company or any of its subsidiaries is engaged at the time
of Senior Advisor's termination of employment under this
Agreement. The activities covered by the previous sentence include,
without limitation, investment banking financial advisory services and
merchant banking and related services. Notwithstanding anything to the
contrary in this Section 10, the foregoing provisions of this Section
11 shall not prohibit the Senior Advisor's providing services to
an entity having a stand-alone business unit which unit would, if
considered separately for purposes of the definition of
"Competitive Enterprise" hereunder,
constitute such a Competitive Enterprise, provided the Senior Advisor
is not providing services to such business unit and provided further
that employment in a senior executive capacity of the business shall be
deemed to be employment in the Competitive Enterprise. Further,
notwithstanding anything in this Section 11, the Senior Advisor shall
not be construed to be in violation of this Section 11 solely by reason
of owning, directly or indirectly, any stock or other securities of a
Competitive Enterprise (or comparable interest, including a voting or
profit participation interest, in any such Competitive Enterprise) if
the Senior Advisor's interest does not exceed 5% of the
outstanding capital stock of such Competitive Enterprise (or comparable
interest, including a voting or profit participation interest, in such
Competitive Enterprise).

(b) The Senior Advisor acknowledges
that the Company or its affiliates is engaged in business throughout
the United States and in various countries outside of the United States
and that the Company intends to expand the geographic scope of its
activities. Accordingly and in view of the nature of his position and
responsibilities, the Senior Advisor agrees that the provisions of this
Section 11 shall be applicable to each state and each foreign country,
possession or territory in which the Company or its affiliates may be
engaged in business during the Employment Term.

(c) The Senior
Advisor agrees that in light of the Senior Advisor's education,
skills, abilities and financial resources, the Senior Advisor will not
assert, and it shall not be relevant nor admissible as evidence in any
dispute arising under this Section 11 that any provisions of this
Section 10 prevent the Senior Advisor from earning a living or
otherwise are or may be void or held unenforceable. In applying this
Section 11, the wishes or preferences of a client or prospective client
of the Company or its affiliates as to who shall perform its services,
or the fact that the client or prospective client of the 

35

Company or its affiliates may also be a
client of a third party with whom the Senior Advisor is or becomes
associated, shall neither be relevant nor admissible as evidence in any
dispute arising under this Section 11.

(d) The Senior Advisor
shall remain subject to the restrictions of this Section 10 until the
termination of the Employment Term.

SECTION
12.    Nonsolicitation.    The Senior agrees that
during the Employment Term, the Senior Advisor will not, directly or
indirectly, for himself or on behalf of any third party at any time in
any manner, solicit, entice, persuade, induce, request or otherwise
cause any employee who is at the associate level or above, officer or
agent of the Company or any of its affiliates to apply for, or accept
employment with, any Competitive Enterprise, or to otherwise refrain
from rendering services to the Company or to terminate his or her
relationship, contractual or otherwise, with the Company or any of its
affiliates, other than in response to a general advertisement or public
solicitation not directed specifically to employees of the Company or
any of its affiliates.

SECTION
13.    Injunctive Relief.    The Senior Advisor
acknowledges and agrees that the Company's remedy at law for any
breach of the covenants contained in Sections 11 or 12 of this
Agreement would be inadequate and that for any breach of such
covenants, the Company shall, in addition to other remedies as may be
available to it at law or in equity, or as provided for in this
Agreement, be entitled to an injunction, restraining order or other
equitable relief, without the necessity of posting a bond, restraining
the Senior Advisor from committing or continuing to commit any
violation of the covenants. The Senior Advisor agrees that proof shall
not be required, that monetary damages for breach of the provisions of
this Agreement would be difficult to calculate and that remedies at law
would be inadequate.

SECTION
14.    Enforceability.    In the event any of the
provisions of Sections 10, 11, 12 or 13 of this Agreement are
determined by a court of competent jurisdiction to be contrary to any
applicable statute, law or rule, or for any reason to be unenforceable
as written, such court may modify any of such provisions so as to
permit enforcement thereof as thus modified.

SECTION
15.    Termination of Agreement.    This Agreement
shall terminate upon the termination of the Employment Term,
provided, however, that Sections 8, 10, 11, 12, 13, 14, 18 and
19 of this Agreement, to the extent applicable, shall survive and
remain in effect notwithstanding the termination of the Employment Term
or a breach by the Company or the Senior Advisor of any other term of
this Agreement.

SECTION 16.    Entire
Agreement.    This Agreement, the Plan and the applicable Award
Agreements thereunder contain the entire understanding and agreement
between the Company and the Senior Advisor concerning the subject
matter hereof and supersede all prior agreements, understandings,
discussions, negotiations and undertakings, whether written or oral,
between the Company and the Senior Advisor with respect thereto.

SECTION 17.    Amendment or Waiver.    No
provision in this Agreement may be amended unless such amendment is
agreed to in writing and signed by the Senior Advisor and an authorized
officer of the Company. No waiver by the Company or by the Senior
Advisor of any breach by the other party to this Agreement of any
condition or provision contained in this Agreement to be performed by
such other party shall be deemed a waiver of a similar or dissimilar
condition or provision at the same or any prior or subsequent time. Any
waiver must be in writing and signed by the Senior Advisor or an
authorized officer of the Company, as the case may be. No failure or
delay by the Company or by the Senior Advisor in exercising any right,
power or privilege under this Agreement shall operate as a waiver
thereof.

SECTION
18.    Severability.    In the event that any provision
or portion of this Agreement shall be determined to be invalid or
unenforceable for any reason, in whole or in part, the remaining
provisions of this Agreement shall be unaffected thereby and shall
remain in full force and effect to the fullest extent permitted by law
so as to achieve the purposes of this Agreement.

SECTION 19.    Governing Law.    This
Agreement shall be governed by and construed in accordance with the
laws of the State of New York without reference to principles of
conflict of laws.

36

SECTION
20.    Notices.    All notices and other communications
required or permitted hereunder shall be in writing (including
