(b)                                 Nonsolicitation. During the Restricted Period the Executive shall not, directly or indirectly, and any entity to which Executive is providing services shall not, directly or indirectly, (i) employ, solicit for employment or otherwise contract for the services of any individual who is or was an employee of the Company; (ii) otherwise induce or attempt to induce any employee of the Company to leave the employ of the Company, or in any way interfere with the relationship between the Company any employee respectively thereof; or (iii) induce or attempt to induce any customer, supplier, licensee or other business relation of the Company or any Affiliate to cease doing business with the Company, or interfere in any way with the relationship between any such customer, supplier, licensee or business relation and the Company.

(c)                                  Non-Disclosure. The Executive shall not (i) divulge, transmit or otherwise disclose , directly or indirectly, other than in the regular and proper course of business of the Company, any trade secrets or other confidential knowledge or information with respect to the operations or finances of the Company or any Affiliates or with respect to confidential or secret processes, services, techniques, customers or plans with respect to the Company (all of the foregoing collectively hereinafter referred to as, “Confidential Information”), or (ii) use, directly or indirectly, any Confidential Information for the benefit of anyone other than the Company; provided, however, that the Executive has no obligation, express or implied, to refrain from using or disclosing to others any such knowledge or information which is or hereafter shall become available to the general public other than through disclosure by the Executive. All Confidential Information, new processes, techniques, know-how, methods, inventions, plans, products, patents and devices developed, made or invented by the Executive, alone or with others, while an employee of the Company which are related to the business of the Company and the Affiliates shall be and become the sole property of the Company, unless released in writing by the Board, and the Executive hereby assigns any and all rights therein or thereto to the Company.

Executive represents that he has delivered to the Company all such Confidential Information and Company property, and has not retained any Confidential Information or Company property (including, without limitations, any copies thereof). However, nothing in this Agreement or elsewhere shall preclude the Executive from retaining, and using appropriately, his rolodex (and electronic equivalents) or documents relating to his personal entitlements and obligations.

(e)                                  Enforcement. The Executive and the Company each acknowledge that a breach of his/its covenants contained in this Section 6 may cause irreparable damage to the other party, the exact amount of which would be difficult to ascertain, and that the remedies at law for any such breach or threatened breach would be inadequate. Accordingly, each party agrees that if he/it breaches or threatens to breach any of the covenants contained in this Section 6, in addition to any other remedy which may be available at law or in equity, the other party shall be entitled to specific performance and injunctive relief to prevent the breach or any threatened breach thereof without bond or other security or a showing that monetary damages will not provide an adequate remedy.

(f)                                   Scope of Covenants. The Company and the Executive further acknowledge that the time, scope, geographic area and other provisions of this Section 6 have been specifically negotiated by sophisticated commercial parties and agree that all such provisions are reasonable under the circumstances of the activities contemplated by this Separation Agreement. In the event that the agreements in this Section 6 shall be determined by any court of competent jurisdiction to be unenforceable by reason of their extending for too great a period of time or over too great a geographical area or by reason of their being too extensive in any other respect, they shall be interpreted to and/or over the maximum geographical area as to which they may be enforceable and/or to the maximum extent in all other respects as to which they may be enforceable, all as determined by such court in such action.

7.                                      Complete Agreement. Company and Executive agree that this Separation Agreement sets forth all of the promises and agreements between them with respect to the subject matter described herein and supersedes all prior and contemporaneous agreements, understandings, inducements or conditions, expressed or implied, oral or written, except as herein contained, with respect to the subject matter described herein. In the event of Executive’s death or a judicial determination of his incapacity, references to the Executive in this Agreement shall be deemed, as appropriate, to be references to his heirs, beneficiaries, estate, executor(s) or other legal representative(s).

8.                                      Cooperation. Executive agrees that upon written request of the Company, he will make himself reasonably available to cooperate with the Company, its subsidiaries and affiliates and any of their officers, directors, shareholders, or employees in connection with any investigation or review by the Company or any federal, state or local regulatory, quasi-regulatory or self-governing authority as any such investigation or review relates to events or occurrences that transpired while Executive was employed by the Company and in respect of which Executive has knowledge (collectively, “Cooperation”). Executive’s Cooperation may include, but not be limited to, being available to meet with directors, officers or employees of the Company and/or the Company’s counsel at mutually convenient times and locations, executing accurate and truthful documents and taking such other actions as may reasonably be requested by the Company and/or the Company’s counsel to effectuate the foregoing. Departing Employee shall be entitled to reimbursement, upon receipt by the Company of suitable documentation, for his reasonable out-of-pocket travel and lodging expenses for such Cooperation.

9.                                      Changes to the Agreement. This Separation Agreement may not be amended or modified unless such amendments or modifications are in writing and signed by Departing Employee and an authorized representative of the Company.

10.                               Remedies. If Executive commits a material breach of any of Executive’s obligations under this Separation Agreement, in addition to any other legal or equitable remedies it may have for such breach, including the remedies in Section 6(f) above, the Company shall be entitled to its attorneys’ fees incurred due to such breach and shall have the right to terminate and recover the payments and benefits provided to Executive under this Separation Agreement. The termination or recovery of such payments or benefits in the event of Executive’s breach will not affect Executive’s continuing obligations under this Separation Agreement. Notwithstanding the foregoing, this Section 10 will not apply if Executive files a claim seeking to invalidate the validity of this Separation Agreement under the ADEA for failure to provide sufficient time for review and revocation as required under this law. For the avoidance of doubt, any filing or assertion of any claim in violation of Section 5 or any other provision of this Separation Agreement shall constitute a breach for purposes of this Section.

11.                               Applicable Law. This Agreement shall in all respects, including all matters of construction, validity and performance, be governed by, and construed and enforced in accordance with, the laws of the State of New York, without regard to any rules governing conflicts of laws.

12.                               Jurisdiction. The Executive and the Company each consents to jurisdiction in the United States District Court for the Southern District of New York, or if that court is unable to exercise jurisdiction for any reason, the Supreme Court of the State of New York, New York County, for any suits, claims or actions concerning this Separation Agreement and each waives any other requirement (whether imposed by statute, rule of court, or otherwise) with respect to personal jurisdiction or service of process and waives any objection to jurisdiction based on improper venue or improper jurisdiction.

13.                               Severability. If any provision of this Separation Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision of this Separation Agreement or any action in any other jurisdiction, but this Separation Agreement shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

14.                               No Waiver. No delay or failure by any party hereto in exercising, protecting, or enforcing any of its rights, titles, interests, or remedies hereunder, and no course of dealing or performance with respect thereto, shall constitute a waiver thereof. The express waiver by a party hereto of any right, title, interest, or remedy in a particular instance or circumstance shall not constitute a waiver thereof in any other instance or circumstance. All rights and remedies shall be cumulative and not exclusive of any other rights or remedies.

15.                               Counterparts. This Separation Agreement may be executed in any number of counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute one and the same instrument.
