10.          Section 409A.  The parties hereby agree that the amounts and benefit payable hereunder are either exempt from or compliant with Section 409A of the Code and the Treasury Regulations and other guidance promulgated thereunder (“Section 409A”), and that the parties shall not, and shall cause their affiliates, successors and assigns not to, take any position inconsistent with such agreement for any reporting purposes, whether internal or external.  This Agreement will be construed and administered to preserve the exemption from Section 409A, and the guidance thereunder of payments that qualify as short-term deferrals pursuant to Treas. Reg. §1.409A-1(b)(4) in respect of the Separation Payments provided for under Section 2.  Notwithstanding anything in this Agreement to the contrary, any payments or benefits due hereunder that constitute non-exempt “deferred compensation” (as defined in Section 409A) that are otherwise payable by reason of Executive’s termination of service will not be paid or provided to Executive until Executive has undergone a “separation from service” (as defined in Section 409A), which the parties agree shall occur on the Termination Date.  If, and only if, Executive is a “specified employee” (as defined in Section 409A) and a payment or benefit provided for in this Agreement would be subject to additional tax under Section 409A if such payment or benefit is paid within six (6) months after Executive’s separation from service, then such payment or benefit shall not be paid (or commence) during the six-month period immediately following Executive’s separation from service, except as provided in the immediately following sentence.  In such an event, any payment or benefits that otherwise would have been made or provided during such six-month period and that would have incurred such additional tax under Section 409A shall instead be paid to Executive in a lump-sum cash payment on the date that is six (6) months after Executive’s separation from service or, if earlier, within five (5) days following the date of Executive’s death.  Executive’s right to receive any installment payments under this Agreement shall be treated as a right to receive a series of separate payments and, accordingly, each such installment payment shall at all times be considered a separate and distinct payment as permitted under Section 409A.  If Executive is

entitled to any reimbursement of expenses or in-kind benefits that are includable in Executive’s federal gross taxable income, the amount of such expenses reimbursable or in-kind benefits provided in any one calendar year shall not affect the expenses eligible for reimbursement or the in-kind benefits to be provided in any other calendar year, and the reimbursement of an eligible expense must be made no later than December 31 of the year after the year in which the expense was incurred. Executive’s right to reimbursement of expenses or in-kind benefits under this Agreement shall not be subject to liquidation or exchange for another benefit.

11.          Public Announcement.  Executive shall have the right to review and approve (such approval not to be unreasonably withheld, conditioned or delayed) any press release or other public announcement made by the Company in connection with the execution of this Agreement and matters relating to this Agreement; provided, that the announcement(s) set forth on Exhibit B attached hereto are approved by Executive.  Without the consent of the other party (such consent not to be unreasonably withheld, conditioned or delayed), neither the Company nor Executive shall make any public announcement concerning Executive’s employment with or termination of employment from the Company, provided that neither party shall be precluded from providing truthful testimony in a court of law, truthful statements to a government official, regulatory or law enforcement agency or pursuant to voluntary requests by SEC staff or a properly issued subpoena, or from making any disclosures required by applicable law or stock exchange rules.

12.          Miscellaneous Provisions.

(a)           Office Items and Pictures.    The Company shall arrange, at the Company’s expense, for the shipping to Executive’s home address of (a) the Executive’s personal items, books, pictures and papers in his office and (b) the various pieces of personal artwork in or around Executive’s office and in the Company’s Parsippany, New Jersey office.

(b)           Effective Date.  This Agreement shall become effective (the “Effective Date”) upon the expiration of the revocation period specified in Section 12(j)(v), provided this Agreement has not previously been revoked in whole or in part.

(c)           Governing Law; Jurisdiction.  This Agreement and the rights and obligations of the parties hereunder shall be construed and enforced in accordance with, and shall be governed by, the laws of the State of New Jersey, without regard to principles of conflict of laws.  The parties hereby consent to the exclusive jurisdiction of the state and federal courts of New Jersey for the resolution of any disputes regarding the terms and subject matter of this Agreement.

(d)           Waiver of Jury Trial.  EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY).

11

(e)           Entire Agreement.  Except as otherwise specifically provided in this Agreement, this Agreement constitutes and contains the entire agreement and understanding between Executive and the Company concerning the subject matters addressed herein and supersedes and replaces all prior negotiations and all agreements, proposed or otherwise, whether written or oral, concerning the subject matter hereof (including, without limitation, the Employment Agreement and the Award Agreements).

(f)            Severability.  If any provision of this Agreement is held invalid, such invalidation shall not affect other provisions of this Agreement and, to this end, the provisions of this Agreement are declared to be severable; provided, however, that if, pursuant to any action brought by Executive, the release set forth in Section 6(a) or any part thereof is declared or adjudged invalid or unenforceable for any reason and, as a result, a claim covered by and released in Section 6(a) (had Section 6(a) or part thereof not been declared or adjudged invalid or unenforceable) is brought by Executive against the Company, the entire Agreement shall be a nullity and all consideration provided in this Agreement shall be repaid by Executive to the Company.

(g)           Amendments.  This Agreement cannot be amended or modified except in writing signed by each of the parties hereto.

(h)           Cooperation in Drafting.  Each party has cooperated in the drafting and preparation of this Agreement.  Hence, in any construction or interpretation of this Agreement or any provision thereof, the same shall not be construed against any party on the basis that such party was the drafter.

(i)            Assignment; Successors and Assigns.  Executive hereby agrees that he may not, directly or indirectly sell or otherwise assign any of his rights, benefits or obligations under this Agreement and that any attempt to do so shall be null and void.  Executive further covenants and agrees that he has not assigned or otherwise transferred any claim released in this Agreement, in whole or party, to any person or entity.  This Agreement and the Release shall inure to the benefit of and shall be binding upon the Company and/or the Company Releasees and all their respective successors and assigns, and any entity with which they may merge or consolidate or to which they may sell all or substantially all their or its assets.
