in the case of acts committed during the Term or in any state of the United

                  (b)      The Employee acknowledges and agrees that

                           (i)      the restrictive covenants set forth in this
Section 8 (the "Restrictive Covenants") are reasonable and valid in geographical
and temporal scope and in all other respects, and

                           (ii)     it is the intention of the parties hereto
that the Restrictive Covenants be enforceable to the fullest extent permitted by
applicable law. Therefore, if any court determines that any of the Restrictive
Covenants, or any part thereof, is invalid or unenforceable, the remainder of
the Restrictive Covenants shall not thereby be affected and shall be given full
force and effect, without regard to the invalid or unenforceable parts.
Specifically, if any court of competent jurisdiction should hold that any
portion of the Restrictive Covenants is overly broad as to one or more states of
the United States or one or more foreign jurisdictions, then that state or
states or foreign jurisdiction or jurisdictions shall be eliminated from the
territory to which the Restrictive Covenants apply and the restrictions shall
remain applicable in all other states of the United States and foreign
jurisdictions.

                  (c) If any court determines that any of the Restrictive
Covenants, or any part thereof, is invalid or unenforceable for any reason, such
court shall have the power to modify such Restrictive Covenant, or any part
thereof, and, in its modified form, such restrictive covenant shall then be
valid and enforceable.

                  9. Equitable Relief. In the event of a breach or threatened
breach by the Executive of any of the covenants contained in this Agreement, the
Company shall be entitled to a temporary restraining order, a preliminary
injunction and/or a permanent injunction restraining the Executive from
breaching or continuing to breach any of said covenants. Nothing herein
contained shall be construed as prohibiting the Company from pursuing any other
remedies that may be available to it under this Agreement for such breach or
threatened breach.

                  10. Severability. Should any provision of this Agreement be
held, by a court of competent jurisdiction, to be invalid or unenforceable, such
invalidity or unenforceability shall not render the entire Agreement invalid or
unenforceable, and this Agreement and each individual provision hereof shall be
enforceable and valid to the fullest extent permitted by law.

                  11.      Successors and Assigns.

Agreement shall inure to the benefit of his heirs, personal representatives,
designees or other legal representatives, as the case may be.

                  (b) This Agreement shall inure to the benefit of and be
binding upon the Company and its successors and assigns. Any Person succeeding

shall assume by contract or operation of law the obligations of the Company
under this Agreement. Provided that Executive's position in such dispute has a
good faith basis, any and all reasonable out of pocket costs incurred by the
Executive in connection with any dispute arising out of this Agreement shall be
immediately paid to the Executive by the Company upon presentation of
appropriate documentation, up to an aggregate amount equal to $170,000.

connection with this Agreement to binding arbitration in accordance with the
rules of the American Arbitration Association. Such arbitration shall be held in
New York City. Each party shall select one arbitrator and the two such selected
arbitrators shall select a third arbitrator. Notwithstanding anything to the
contrary in this Section 12, such parties may seek in any court of competent
jurisdiction any injunctive relief pursuant to Section 9 of this Agreement.

                  13. Notices. All notices, requests and demands given to or
made upon the respective parties hereto shall be deemed to have been given when

prior contracts, understandings, discussions and agreements relating to
employment between the Executive and the Company and constitutes the complete
understanding between the parties with respect to the subject matter hereof. No
statement, representation, warranty or covenant has been made by either party
with respect to the subject matter hereof except as expressly set forth herein

thereof or the exercise of any other right, power or privilege.
