                                   TERMINATION

     7.01    The Corporation may terminate the employment of Executive
hereunder:

             (i)    By giving Executive notice in writing at any time specifying
     a termination date not less than twelve (12) months after the date on which
     such notice is given, in which event Executive's employment hereunder shall
     terminate on the date specified in such notice provided, however, that, in
     such event, Executive will be permitted to seek other employment
     immediately; or

             (ii)   By giving Executive notice in writing at any time specifying
     a termination date less than twelve (12) months after the date on which
     such notice is given. In this event Executive's employment hereunder shall
     terminate on the date specified in such notice and the Corporation shall
     thereafter pay him a sum equal to the amount by which twelve (12) months
     salary at his then current rate exceeds the salary paid to him for the
     period from the date on which such notice is given to the termination date
     specified in such notice. Such payment shall be made during the period
     immediately following the termination date specified in such notice, in
     successive equal monthly installments each of which shall be equal to one
     (1) month's salary at the rate in effect at the time of such termination,
     with any residue in respect of a period less than one (1) month to be paid
     together with the last installment.

     During the termination period provided in subsection (i), or in the case of
a termination under subsection (ii) providing for a termination period of less
than twelve (12) months, for a period of twelve (12) months after the
termination notice, Executive will be entitled to receive all

                                       -6-
<Page>

employee benefits and executive perquisites accorded to him prior to
termination, including, but not limited to, eligibility for an MICP award
pursuant to Section 4.01, and Executive shall be treated as still employed by
the Corporation during such period for purposes of the Corporation 's LTPIP,
ESBA and Stock Incentive Plans provided, that such employee welfare benefits
shall cease upon such date that Executive accepts employment with another
employer offering similar benefits.

     7.02    Notwithstanding the provisions of Section 7.01, If Executive
obtains other employment (including work as a consultant, independent contractor
or establishing his own business) during the period of notice of termination,
Executive will promptly notify the Corporation.

     7.03    Executive may at any time give notice in writing to the Corporation
specifying a termination date not less than ninety (90) days after the date on
which such notice is given, in which event his employment hereunder shall
terminate on the date specified in such notice, and Executive shall receive his
salary, employee benefits and executive perquisites until the termination date.
Provided however that the Corporation may, at its option, upon receipt of such
notice determine an earlier termination date.

     7.04    Notwithstanding the provisions of Section 7.01, the Corporation may
terminate the employment of Executive hereunder, at any time after the

following:

             (i)    Any material breach by Executive of any provision of any
     material agreement with the Corporation (including without limitation
     Sections 8.01 and 8.02 hereof) upon notice of same by the Corporation which
     breach, if capable of being cured,

                                       -7-
<Page>

     has not been cured within fifteen (15) days after such notice (it being
     understood and agreed that a breach of Section 8.01 or 8.02 hereof, among
     others, shall be deemed not capable of being cured);

             (ii)   Misappropriation by Executive of funds or property of the
     Corporation or any attempt by Executive to secure any personal profit
     related to the business of the Corporation (other than as permitted by this
     Agreement) and not fairly disclosed to and approved by the Board of
     Directors;

             (iii)  Fraud, dishonesty, gross negligence or willful misconduct on
     the part of Executive in the performance of his duties as an employee of
     the Corporation;

             (iv)   A felony conviction of Executive involving moral turpitude.

     Upon a termination for Cause, the Corporation shall pay Executive his
salary through the date of termination of employment, and Executive shall not be
entitled to any other payments hereunder, provided however, that Executive shall
retain the right to all employee benefits in which he is vested as of the date
of termination of employment.

     7.05    Executive may terminate his employment with the Corporation for

             (i)    the assignment to Executive of any duties inconsistent in
     any material respect with Section 2.01, or any other action by the
     Corporation that results in a material

                                       -8-
<Page>

     diminution in the Executive's position or authority, duty, titles,
     responsibilities, or reporting requirements other than an isolated,
     insubstantial and inadvertent action that is not taken in bad faith;

             (ii)   any material failure by the Company to comply with any
     provision of Articles III, IV, V, VI, or IX of this Agreement, other than
     an isolated, insubstantial and inadvertent failure that is not taken in bad
     faith;

             (iii)  any relocation of the Executive's principal business
     location to a location other than the New York Metropolitan area (within
     fifty (50) miles of Manhattan); or

             (iv)   the Executive is not elected or reelected, as appropriate,
     to the Board.

In the event of a termination for Good Reason, all of the compensation, benefits
and perquisites provided by Section 7.01 shall apply as if Executive were
terminated by the Corporation.

                                  ARTICLE VIII

may hereafter acquire any securities of any class of any publicly-owned company
and may serve on the boards of directors of other corporations (or the

the Corporation, divulge, furnish or make known or accessible to, or use for the
benefit of, anyone other than the Corporation and its subsidiaries and
affiliates any information of a confidential nature relating in any way to the
business of the Corporation or its subsidiaries or affiliates or their clients
and obtained by him in the course of his employment hereunder other than as
required by law or by subpoena pursuant to any judicial or administrative
proceeding, provided however that Executive will provide notice to, and, if
permissible will confer, with the Corporation's legal counsel prior to any such
disclosure.

     8.03    All records, papers and documents kept or made by Executive
relating to the business of the Corporation or its subsidiaries or affiliates or

employment.

     8.06    If at the time of enforcement of any provision of this Agreement, a
court shall hold that the duration, scope or area restriction of any provision
hereof is unreasonable under circumstances now or then existing, the parties
hereto agree that the maximum duration, scope or area reasonable under the
circumstances shall be substituted by the court for the stated duration, scope
or area.

     8.07    Executive acknowledges that a remedy at law for any breach or
attempted breach of Article VIII of this Agreement will be inadequate, and
agrees that the Corporation shall be entitled to specific performance and
injunctive and other equitable relief in the case of any such breach or
attempted breach.

     8.08    Executive represents and warrants that neither the execution and
delivery of this Employment Agreement nor the performance of Executive's

to which Executive is a party or by which he may be bound or affected, in
particular the terms of any employment agreement to which Executive may be a
party. Executive and the Corporation each further represent and warrant to the
other that

each has full right, power and authority to enter into and carry out the
