                  (A) continued payments of the Base Salary, payable in
         installments in accordance with the Company's regular payroll policies,
         for the period beginning on the Date of Termination and ending on the
         second anniversary of the Date of Termination (the "Severance Period");

                  (B) a portion of Executive's Bonus for the fiscal year of the
         Company that includes the Date of Termination, such portion to equal
         the product (such product, the "Pro Rata Bonus") of (1) the Bonus that
         would have been payable to Executive for such year had he remained
         employed for the entire fiscal year and had Executive and the Company
         each achieved (but not exceeded) the target performance objectives for
         such year established by the Board or a committee thereof, multiplied
         by (2) a fraction, the numerator of which is equal to the number of
         days in such fiscal year that precede the Date of Termination and the
         denominator of which is equal to 365, such amount to be payable to
         Executive within five business days following the date (the "Bonus
         Payment Date") annual bonuses for such fiscal year are actually paid by
         the Company to its active executives;

                                       5
<PAGE>
         the Company that includes the Date of Termination and the second such
         installment to be paid within five business days following the Bonus
         Payment Date for the next succeeding fiscal year of the Company;

                   (D) continued coverage during the Severance Period under the
         Company's medical and health insurance plans referred to in Section 5
         (the "Continued Benefits") for Executive and his eligible dependents
         participating in such plans immediately prior to the Date of
         Termination, subject to timely payment by Executive of all premiums,
         contributions and other co-payments required to be paid by senior
         executives of the Company under the terms of such plans as in effect
         from time to time.

                  The term "Average Annual Bonus" means the average of the
annual cash bonuses plus the value at the time of award of any non-cash bonuses
paid to Executive for each of the three complete fiscal years of the Company
ending immediately prior to the Date of Termination during which Executive was
employed by the Company or, if Executive has been employed by the Company for an
aggregate period of less than three fiscal years, the average of the annual
bonuses paid to Executive by the Company for Executive's period of employment.

                  (i) Executive shall not have a duty to mitigate the costs to
the Company under this Section 7 (f) (i), nor shall any payments from Company to
Executive of Base Salary, Average Annual Bonus and Pro Rata Bonus be reduced,
offset or canceled by any compensation or fees earned by (whether or not paid
currently) or offered to Executive during the Severance Period by a subsequent
employer or other Person (as defined below) for which Executive performs
services, including but not limited to consulting services. The foregoing
notwithstanding, should Executive receive benefits coverage by a subsequent
employer during the Severance Period, all health and medical benefits coverage
provided by the Company to Executive shall immediately terminate.

                  (ii) If Executive's employment shall terminate upon his death
or Disability or if the Company shall terminate Executive's employment for Cause
or Executive shall terminate his employment without Good Reason in any such case
during the Employment Period, the Company shall pay to Executive (or, in the
event of Executive's death, to his estate) the Accrued Obligations within 30
days following the Date of Termination. In addition, if Executive's employment
shall terminate upon his death or Disability during the Employment Period, the
Company shall pay to Executive (or, in the event of Executive's death, to his
estate) the Pro Rata Bonus, if any, in one lump sum within five business days
following the Bonus Payment Date for the fiscal year of the Company that
includes the Date of Termination.

                  (iii) Except as specifically set forth in this Section 7(f),
no benefits payable to Executive under any otherwise applicable plan, policy,
program or practice of the Company or its Affiliates in which Executive was a
participant during his employment with the Company or its Affiliates shall be
limited by this Section 7(f), provided that Executive shall not be entitled to
receive any payments or benefits under any such plan, policy, program or
practice providing any bonus or incentive compensation or severance compensation
or benefits (and the provisions of this Section 7(f) shall supersede the
provisions of any such plan, policy, program or practice).

from all Board memberships and other positions then held by him with the Company
and its Affiliates.

                  8. Unauthorized Disclosure. During the period of Executive's
employment with the Company and following any termination of such employment,

or data or any reproduction thereof, or any documents containing or pertaining
to any Confidential Information.

                  13. Work Product. Executive agrees to disclose in confidence
to the Company any and all inventions, improvements, designs, original works of
authorship, formulas, processes, computer software programs, databases and trade
secrets (including, but not limited to, market information and marketing
designs, proposals and concepts) (all taken together, the "Developments") that
Executive makes, conceives, first reduces to practice, or creates, either alone
or jointly with others while Executive is employed by the Company and that: (a)
result from any work performed by Executive for the Company, whether or not in
the normal course of Executive's duties or during normal business hours; (b)
reasonably relate to the actual or anticipated business, services, products,
research or development of Executive; or (c) are developed with the use of the
Company time, equipment, supplies or facilities. Executive must promptly
disclose Developments to the Company whether or not such Developments are
patentable, copyrightable or protectible as trade secrets. Executive understands
and agrees that all Developments shall be the sole and exclusive property of the
Company and shall constitute "work made for hire" (as that term is defined under
Section 101 of the U.S. Copyright Act, 17 U.S.C. Section 101) with the Company
being the person for whom the work was prepared and that all intellectual
property rights therein shall be the sole and exclusive property of the Company,
and that in the event that any such Development is deemed not to be a "work made
for hire," Executive hereby irrevocably assigns, transfers and conveys to the
Company, exclusively and perpetually, all right, title and interest which
Executive may have or acquire in and to such Development throughout the world,
including without limitation any copyrights and patents, and the right to secure
registrations, renewals, reissues, and extensions thereof. Executive agrees to
sign any documents and to do all things necessary, without additional
compensation, whether during Executive's employment or after, to assist the
Company to register, perfect, maintain


                                       8
<PAGE>
and/or enforce the Company's rights in any Development, including without
limitation any patent, copyright, trade secret or other right or interest.

                  14. Injunctive Relief with Respect to Covenants; Forum, Venue
and Jurisdiction. Executive acknowledges and agrees that the covenants,
obligations and agreements of Executive contained in Sections 8, 9, 10, 11, 12,
13 and 14 relate to special, unique and extraordinary matters and that a
violation of any of the terms of such covenants, obligations or agreements will
cause the Company irreparable injury for which adequate remedies are not
available at law. Therefore, Executive agrees that the Company shall be entitled
to an injunction, restraining order or such other equitable relief (without the
requirement to post bond) as a court of competent jurisdiction may deem
necessary or appropriate to restrain Executive from committing any violation of
such covenants, obligations or agreements. These injunctive remedies are
cumulative and in addition to any other rights and remedies the Company may
have. The Company and Executive hereby irrevocably submit to the exclusive
jurisdiction of the courts of New York, and the Federal courts of the United
States of America, in each case located in New York City in respect of the
injunctive remedies set forth in this Section 14 and the interpretation and
enforcement of Sections 8, 9, 10, 11, 12, 13 and 14 insofar as such
interpretation and enforcement relate to any request or application for
injunctive relief in accordance with the provisions of this Section 14, and the
parties hereto hereby irrevocably agree that (a) the sole and exclusive
appropriate venue for any suit or proceeding relating solely to such injunctive
relief shall be in such a court, (b) all claims with respect to any request or
application for such injunctive relief shall be heard and determined exclusively
in such a court, (c) any such court shall have exclusive jurisdiction over the
person of such parties and over the subject matter of any dispute relating to
any request or application for such injunctive relief, and (d) each hereby
waives any and all objections and defenses based on forum, venue or personal or
subject matter jurisdiction as they may relate to an application for such
injunctive relief in a suit or proceeding brought before such a court in
accordance with the provisions of this Section 14. All disputes not relating to
any request or application for injunctive relief in accordance with this Section
14 shall be resolved by arbitration in accordance with Section 17 (b).

                  Notwithstanding any other provision hereof, the Company's
obligations to pay Executive any amount or provide Executive with any benefit or
right pursuant to Section 7(f) is subject to Executive's compliance with his
obligations under Sections 8 through 14, inclusive.

                  15. Assumption of Agreement. The Company shall require any
Successor thereto, by agreement in form and substance reasonably satisfactory to
Executive, to expressly assume and agree to perform this Agreement in the same
manner and to the same extent that the Company would be required to perform it
if no such succession had taken place. Failure of the Company to obtain such
agreement prior to the effectiveness of any such succession shall be a breach of
this Agreement and shall entitle Executive to compensation from the Company in
the same amount and on the same terms as Executive would be entitled hereunder
if the Company had terminated Executive's employment Without Cause as described
in Section 7, except that for purposes of implementing the foregoing, the date
on which any such succession becomes effective shall be deemed the Date of
Termination.

                  16. Entire Agreement. This Agreement (including the Exhibit
hereto) constitutes the entire agreement among the parties hereto with respect
to the subject matter


                                       9

hereof. All prior correspondence and proposals (including but not limited to
summaries of proposed terms) and all prior promises, representations,
understandings, arrangements and agreements relating to such subject matter
(including but not limited to those made to or with Executive by any other
Person and those contained in any prior employment, consulting or similar
agreement entered into by Executive and the Company or any predecessor thereto
or Affiliate thereof) are merged herein and superseded hereby.

                  17. Miscellaneous.

                  (a) Binding Effect; Assignment. This Agreement shall be
binding on and inure to the benefit of the Company and its successors and
permitted assigns. This Agreement shall also be binding on and inure to the
benefit of Executive and his heirs, executors, administrators and legal
representatives. This Agreement shall not be assignable by any party hereto
without the prior written consent of the other parties hereto, except as
provided pursuant to this Section 17(a). The Company may effect such an
assignment without prior written approval of Executive upon the transfer of all
or substantially all of its business and/or assets (by whatever means), provided
that the Successor to the Company shall expressly assume and agree to perform
this Agreement in accordance with the provisions of Section 15.

                  (b) Arbitration. Any dispute or controversy arising under or
in connection with this Agreement (except in connection with any request or
application for injunctive relief in accordance with Section 14) shall be
resolved by binding arbitration. The arbitration shall be held in New York City
and, except to the extent inconsistent with this Agreement, shall be conducted
in accordance with the Commercial Arbitration Rules of the American Arbitration
Association then in effect at the time of the arbitration, and otherwise in
accordance with principles which would be applied by a court of law or equity.
The arbitrator shall be acceptable to both the Company and Executive. If the
parties cannot agree on an acceptable arbitrator, the dispute shall be heard by
a panel of three arbitrators, one appointed by the Company, one appointed by
Executive, and the third appointed by the other two arbitrators. All expenses of
arbitration shall be borne by the party who incurs the expense, or, in the case
of joint expenses, by both parties in equal portions.

                  (c) 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 conflicts of laws.

                  (d) Taxes. The Company may withhold from any payments made
under this Agreement all applicable taxes, including but not limited to income,
employment and social insurance taxes, as shall be required by law.

                  (e) Amendments. No provision of this Agreement may be
modified, waived or discharged unless such modification, waiver or discharge is
approved by the Board or a Person authorized thereby and is agreed to in writing
by Executive. No waiver by any party hereto at any time of any breach by any
other party hereto of, or compliance with, any condition or provision of this
Agreement to be performed by such other party shall be deemed a waiver of
similar or dissimilar provisions or conditions at the same or at any prior or
subsequent time. No waiver of any provision of this Agreement shall be implied
from any course of dealing between


                                       10

or among the parties hereto or from any failure by any party hereto to assert
its rights hereunder on any occasion or series of occasions.

                  (f) Severability. In the event that any one or more of the
provisions of this Agreement shall be or become invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein shall not be affected thereby.
