4

Incentive Compensation Recoupment Policy (copies of which are enclosed with this Offer Letter).

(b) You hereby represent to the Company that you are under no obligation or agreement that would prevent you from becoming an employee of the Company or adversely impact your ability to perform the expected responsibilities. By accepting this offer, you agree that no trade secret or proprietary information not belonging to you or the Company will be disclosed or used by you at the Company.

(c) This Offer Letter is not an employment contract and does not create an implied or express guarantee of continued employment. By accepting this offer, you are acknowledging that you are an employee at-will. This means that either you or the Company may terminate your employment at any time and for any reason or for no reason. This Offer Letter contains the entire agreement and understanding between you and the Company with respect to the terms of your employment and supersedes any prior or contemporaneous agreements, understandings, communications, offers, representations, warranties, or commitments by or on behalf of the Company, whether written or oral, with respect to the terms of your employment. Except for amendments to increase compensation payable to you, the terms of this Offer Letter may not be amended except pursuant to a written agreement between you and the Company.

(d) Section 409A

(i) The intent of the parties is that payments and benefits under this Offer Letter comply with or be exempt from Internal Revenue Code Section 409A and the regulations and guidance promulgated there under (collectively "Section 409A") and, accordingly, to the maximum extent permitted, this Offer Letter shall be interpreted to be exempt from Section 409A or in compliance therewith, as applicable. If you notify the Company that you have received advice of tax counsel of national reputation with expertise in Section 409A that any provision of this Offer Letter (or of any award of compensation, including equity compensation or benefits) would cause you to incur any additional tax or interest under Section 409A (with specificity as to the reason thereof) or the Company independently makes such determination, the Company shall, after consulting with you, reform such provision to try to comply with Section 409A through good faith modifications to the minimum extent reasonably appropriate to conform with Section 409A. To the extent that any provision hereof is modified in order to comply with or be exempt from Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit to you and the Company of the applicable provision without violating the provisions of Section 409A.

(ii) A termination of employment shall not be deemed to have occurred for purposes of any provision of this Offer Letter providing for the payment of any amounts or benefits that are considered nonqualified deferred compensation under Section 409A upon or following a termination of employment, unless such termination is also a

5

"separation from service" within the meaning of Section 409A and the payment thereof prior to a "separation from service" would violate Section 409A. For purposes of any such provision of this Offer Letter relating to any such payments or benefits, references to a "termination," "termination of employment" or like terms shall mean "separation from service."

(iii) If, as of the date of your "separation from service" from the Company, you are a "specified employee" (within the meaning of that term under Section 409A(a)(2)(B)), then with regard to any payment or the provision of any benefit that is considered "nonqualified deferred compensation" under Section 409A (whether under this Offer Letter, any other plan, program, payroll practice or any equity grant) and is payable upon your separation from service, such payment or benefit shall not be made or provided until the date which is the earlier of (A) the expiration of the six (6) month-and­one-day period measured from the date of your "separation from service," and (B) the date of your death (the "Delay Period") and this Offer Letter and each such plan, program, payroll practice or equity grant shall hereby be deemed amended accordingly. Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this paragraph (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to you in a lump sum with interest at the prime rate as published in the Wall Street Journal on the first business day of the Delay Period (providedthat any payment measured by a change in value that continues during the Delay Period shall not be credited with interest for the Delay Period), and any remaining payments and benefits due under this Offer Letter shall be paid or provided in accordance with the regularly scheduled payment dates specified for them herein.

(iv) For purposes of Section 409A, your right to receive any installment payments pursuant to this Offer Letter shall be treated as a right to receive a series of separate and distinct payments. Whenever a payment under this Offer Letter specifies a payment period with reference to a number of days (e.g.,"payment shall be made within thirty (30) days following the date of termination"), the actual date of payment within the specified period shall be within the sole discretion of the Company.

(v) To the extent any reimbursement or in-kind payment provided pursuant to this Offer Letter is deemed nonqualified deferred compensation subject to Section 409A then (i) all such expenses or other reimbursements as provided herein shall be payable in accordance with the Company’s policies in effect from time to time, but in any event shall be made on or prior to the last day of the taxable year following the taxable year in which such expenses were incurred by you; (ii) no such reimbursement or expenses eligible for reimbursement in any taxable year shall in any way affect the expenses eligible for reimbursement in any other taxable year; and (iii) the right to such reimbursement or in-kind benefits shall not be subject to liquidation or exchanged for another benefit.

6

(vi) No amounts payable to you by the Company or any of its subsidiaries or affiliates under this Agreement or any other agreement that constitute nonqualified deferred compensation subject to Section 409A shall be subject to offset by any other amount, except as permitted under Section 409A.

(e) Withholding. The Company may withhold any tax (or other governmental obligation) that may result from the payments made and benefits provided to you under this Offer Letter

7

or require you to make other arrangements satisfactory to the Company to enable it to satisfy all such withholding requirements.

(f) Governing Law; Waiver of Jury Trial. All matters affecting this Offer Letter, including the validity thereof, are to be governed by, and interpreted and construed in accordance with, the laws of the State of New Jersey applicable to contracts executed in and to be performed in that State. YOU AND THE COMPANY HEREBY ACKNOWLEDGE AND AGREE THAT YOU AND THE COMPANY ARE HEREBY WAIVING ANY RIGHTS TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER YOU OR THE COMPANY AGAINST THE OTHER IN CONNECTION WITH ANY MATTER WHATSOEVER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS OFFER LETTER. Disputes regarding your application for employment, employment, or termination of employment will be subject to the attached Arbitration Agreement.

(g) Remedies. In addition to all other legal and equitable remedies, the prevailing party in any dispute that in any way relates to this Offer Letter or your employment hereunder shall be entitled to recover his or its reasonable attorneys’ fees and expenses incurred in connection with such dispute.

United States law requires all companies to verify an employee's authorization to work in the United States. If you accept this offer, you will need to bring certain documents with you on your Commencement Date which allows the Company to verify your work authorization. Enclosed is an Employment Eligibility Verification (form I-9). Please review the form and bring the appropriate documents required for employment verification on your Commencement Date. You will be asked to complete the form in the presence of a witness on your Commencement Date.

If these terms are agreeable to you, please sign and date the Offer Letter in the appropriate space at the bottom and return it to me by Monday, June 8, 2015.
