     8. TERMINATION OF EMPLOYMENT. The Employee’s employment with the Company
may be terminated as follows:

          (a) WITH CAUSE. The Employee’s employment with the Company may be
terminated by the Company at any time for “Cause.” As used herein, the term
“Cause” shall refer to the following: (i) theft, fraud, dishonesty, gross
negligence or willful malfeasance by the Employee in connection with the
performance of his duties hereunder (collectively, “Theft Events”); (ii) a
material breach or failure to fulfill and perform the Employee’s duties
hereunder, which breach or failure is not cured to the reasonable satisfaction
of the Company within forty-five (45) days after written demand

3

--------------------------------------------------------------------------------

 

from the Company (if such breach is at all curable during such time in the
reasonable determination of the Company; failing such determination, “Cause”
shall have occurred upon the occurrence of such breach or failure); (iii)
conviction of a felony or a crime involving moral turpitude; (iv) habitual
neglect of duties or misconduct in the performance of the Employee’s duties and
responsibilities hereunder following an initial notice of warning from the

with the reasonable directions and instructions of management of the Company in
connection with the performance of the Employee’s duties and responsibilities
hereunder following an initial notice of warning from the Company with respect
thereto. Upon termination for Cause, all rights of the Employee under this
Agreement shall immediately terminate and the Company shall have no further
obligations. A termination of the Employee’s employment with the Company by the
Employee upon his voluntary resignation or voluntary retirement shall be treated
as a termination for Cause hereunder. In connection therewith, the Employee
covenants and agrees not to voluntarily resign or voluntarily retire without
providing the Company with ninety (90) days’ prior written notice. Upon a
termination for Cause, Employee shall receive in full satisfaction of all
amounts due to him an amount equal to the remainder of Base Compensation through
date of termination. Notwithstanding any of the foregoing, in the event that the
Company has terminated Employee’s employment on account of a Theft Event, the
Company shall be entitled to withhold from any amounts otherwise due to Employee
under this Subsection 8(a) the amount of monetary damages incurred by the
Company from such Theft Event which shall be quantified and determined in
writing by the Company within 90 days after the date of termination. The
Employee agrees that his eligibility to receive any and all amounts described in
this Section 8(a) shall be subject to and contingent upon the Employee’s
execution of a full and complete general release in favor of the Company and its
affiliated persons and entities, satisfactory to the Company in its sole
discretion.

          (b) WITHOUT CAUSE. The Employee’s employment with the Company may be
terminated by the Company at any time without Cause, but in the event of any
such termination pursuant to this Section 8(b), the Company will pay, in
addition to any other amounts due hereunder, the Employee severance pay in an
amount equal to the greater of (i) the balance of all of Employee’s remaining
and unpaid Base Compensation due for the balance of the then existing term
hereunder, or (ii) 90 days of Base Compensation, payable upon execution and
delivery of the release described below, less all required withholdings and in
accordance with then current payroll practices of the Company and applicable law
or regulation. In addition, Employee shall receive any accrued but unpaid
vacation time for the current Employment Year. The Employee agrees that his
eligibility to receive any and all amounts described in this Section 8(b) shall
be subject to and contingent upon the Employee’s execution of a full and
complete general release in favor of the Company and its affiliated persons and
entities, satisfactory to the Company in its sole discretion.

          (c) TERMINATION FOR DEATH OR DISABILITY. The Employee’s employment
hereunder shall terminate immediately upon the Employee’s death or Disability.
For purposes of the preceding sentence, the term “Disability” shall mean the
Employee’s inability, by reason of physical or mental incapacity (determined by
a licensed physician reasonably acceptable to the Employee and the Company), to
perform the

4

--------------------------------------------------------------------------------

 

essential functions of his job, with or without a reasonable accommodation by
the Company, for an aggregate of ninety (90) days during any twelve (12) month
period, provided further that during any such continuous period, the Employee’s
Base Compensation payable under Section 6(a) shall be reduced by the amount, if
any, of payments to the Employee under any short-term or long-term disability
insurance policy, plan or program maintained by the Company. During any period
when the Employee implicitly or explicitly purports to be unable to perform his
duties hereunder by reason of physical or mental illness, incapacity or
disability, the Employee, at the request and expense of Company, shall submit to
one or more examinations by a physician of the Company’s choice. A termination
of the Employee’s employment with the Company due to any of the foregoing
provisions of this Section 8(c) shall be treated as a termination without Cause
hereunder.

          (d) TERMINATION BY EMPLOYEE FOR GOOD REASON. Employee shall have the
right to terminate this Agreement for “Good Reason”. The following events
affecting Employee shall constitute “Good Reason” within the meaning of this
Agreement: (i) if Employee, at any time during the Employment Period (except
during a period of Disability), has suffered a material change or diminution in
duties and responsibilities from those contemplated herein, or (ii) if there is
a Change of Control Event, as defined below.

     For purposes of this Employment Agreement, a “Change of Control” shall mean
the happening of any of the following:

“Exchange Act”) (other than the Company and its subsidiaries as determined
immediately prior to that date) of beneficial ownership, directly or indirectly
(with beneficial ownership determined as provided in Rule 13d-3, or any
successor rule, under the Exchange Act), of a majority of the total combined
voting power of all classes of stock of the Company having the right under
ordinary circumstances to vote at an election of the Board of Directors of the

the date of this Agreement;

          (ii) the election to the Board of Directors of the Company of members
as a result of which a majority of the Board of Directors shall consist of

of the Company;

          (iii) the date of approval by the stockholders of the Company of an
agreement providing for the merger or consolidation of the Company with another
corporation or other entity where (x) stockholders of the Company immediately
prior to such merger or consolidation would not beneficially own following such
merger or consolidation shares entitling such stockholders to 50% or more of all
votes (without consolidation of the rights of any class of stock to elect
directors by a separate class vote) to which all stockholders of the surviving
corporation would be entitled in the election of directors, or (y) where the
members of the Board of Directors, immediately prior to such

5

--------------------------------------------------------------------------------

 

merger or consolidation, would not, immediately after such merger or
consolidation, constitute a majority of the board of directors of the surviving
corporation; or

          (iv) the sale of all or substantially all of the assets of the
Company.

               (e) STATUS UPON TERMINATION. The termination of this Agreement,

of the other provisions of this Section 9 in any other respect, or of any other
provision of this Agreement. In the event that any provision of this Section 9
shall be held invalid or unenforceable by a court of competent jurisdiction by
reason of the geographic or business scope or the duration thereof or for any
other reason, such invalidity or unenforceability shall attach only to the
particular aspects of such provision found invalid or unenforceable as applied
and shall not affect or render invalid or unenforceable any other provision of
this Section 9 or the enforcement of such provision in other circumstances, and

agrees to bring all business opportunities to the Company relating to or

this Agreement, including compilations of lists or data, the Employee agrees
that all such works will be prepared as “work-for-hire” within the meaning of
the Copyright Act of 1976, as amended (the “Act”), of which the Company shall be
considered the “author” within the meaning of the Act. In the event (and to the
extent) that such works or any part or element thereof is found as a matter of
law not to be a “work-for-hire” within the meaning of the Act, the Employee
hereby assigns to the Company the sole and exclusive right, title and interest
in and to all such works, and all copies of any of them, without further
consideration, and agrees, to the extent reasonable under the circumstances, to
cooperate with the Company to register, and from time to time to enforce, all
patents, copyrights and other rights and protections relating to such works in
any and all countries. To that end, the Employee agrees to execute and deliver
all documents requested by the Company in connection therewith, and the Employee
hereby irrevocably designates and appoints the Company as the Employee’s agent
and attorney-in-fact to act for and on behalf of the Employee and in the
Employee’s stead to execute, register and file any such applications, and to do
all other lawfully permitted acts to further the registration, protection and
issuance of patents, copyrights or similar protections with the same legal force
and effect as if executed by the Employee. The Company shall reimburse the
Employee for all reasonable costs and expenses incurred by the Employee pursuant
to this Section 11.

--------------------------------------------------------------------------------

 

     12. NO DISPARAGING STATEMENTS. During the Term of employment and for one
(1) year after termination of this Agreement for any reason whatsoever, the
Employee and the Company agree to refrain from making any disparaging
statements, either orally or in writing, about the other party (and, on the part
of the Employee, about any affiliate of the Company, or any directors, officers,
shareholders, employees, agents or other representatives of the Company or any
affiliate thereof).

     13. SURVIVAL. The provisions of Sections 8(b), 8(c), 8(d), 8(f), 9, 11, 12,
14, 15, 16 and 17 hereof shall survive the termination of this Agreement for the
applicable time period necessary to fully effectuate the provisions of such
sections.

     14. COMPLIANCE WITH OTHER AGREEMENTS. The Employee and the Company each
hereby represent and warrant to the other that the execution and delivery of
this Agreement and the performance of such party’s obligations hereunder will
not, with or without the giving of notice and/or the passage of time, (i)
violate any judgment, writ, injunction or order of any court, arbitrator or
governmental agency applicable to such party, or (ii) conflict with, result in
the breach of any provision of or the termination of, or constitute a default
under, any agreement to which such party is a party or by which such party is or
may be bound. The parties agree to indemnify and hold harmless each other from
any liability, judgment or claim incurred, entered or made against such party
based on its reliance on the representations and warranties made in this Section
14, including all costs and expenses and attorney’s fees incurred or paid by
such party in connection with the foregoing.

     15. INJUNCTIVE RELIEF. The Employee acknowledges and agrees that the
Company and its affiliates are engaged in a highly competitive business and that
the protections of the Company and each such affiliate set forth in Sections 9,
10 and 11 of this Agreement are fair and reasonable and are of vital concern to
the Company and its affiliates. Further, the Employee acknowledges and agrees
that monetary damages for any violation of such Sections will not adequately
compensate the Company and its affiliates with respect to any such violation.
Therefore, in the event of a breach by the Employee of any of the terms and
provisions contained in Sections 9, 10 or 11 hereof, the Company shall be
entitled to institute legal proceedings to enforce the specific performance of
this Agreement by the Employee and to enjoin the Employee from any further
violations. The remedies available to the Company pursuant to this Section 15
may be exercised cumulatively by the Company in conjunction with all other
rights and remedies provided by law.

     16. ARBITRATION OF DISPUTES. If any dispute shall arise between the
Employee and the Company in connection with this Agreement, and such dispute
cannot be resolved amicably by the parties, the same shall be conclusively and
finally resolved by binding arbitration. Any party hereto may commence an
arbitration proceeding by providing written notice to the other party requesting
the arbitration of an unresolved dispute. Each such dispute, if any, shall be
submitted to an arbitrator acceptable to both parties. If either the Employee or
the Company refuses or neglects to agree to appoint an arbitrator within thirty
(30) days after receipt of written notice from the other party requesting the
other party to do so, the American Arbitration Association may appoint such

9

--------------------------------------------------------------------------------

 

arbitrator. The arbitrator shall be experienced in the subject matter of the
dispute. Except as otherwise specifically set forth herein, the arbitrators
shall conduct the arbitration in accordance with the Commercial Arbitration
Rules of the American Arbitration Association. The decision in writing of the
arbitrator, when filed with the parties hereto, shall be final and binding on
both parties. Judgment may be entered upon the final decision of the arbitrator
in any court having jurisdiction. Such arbitration shall take place in New York,
New York.

     Notwithstanding anything to the contrary contained in this Section 16,
nothing shall prohibit the Company or Employee from pursuing all legal and
equitable remedies available to the Company or Employee in order to enforce the
provisions of Sections 9, 10 and 11 of this Agreement. To the extent that any
court action is permitted consistent with or to enforce this Agreement, the
parties hereby consent to the jurisdiction of the federal or state courts
sitting in any state where the Company maintains an office. Accordingly, with
respect to any such court action, all of the parties hereto (a) submit to the
personal jurisdiction of such courts, (b) consent to service of process and (c)
waive any other requirement (whether imposed by statute, rule of court, or
otherwise) with respect to personal jurisdiction or service of process.

     17. AMENDMENT; WAIVER; DISCHARGE. No provision of this Agreement may be
amended, waived or discharged unless such amendment, waiver or discharge is
agreed to in writing and signed by the Employee and a duly authorized
representative of the Company. No waiver by either party hereto at any time of
any breach by the 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.

     18. VALIDITY. The invalidity or unenforceability of any provision or
provisions of this Agreement shall not affect the validity or enforceability of
any other provision of this Agreement, which shall remain in full force and
