ARTICLE II EMPLOYMENT BY THE COMPANY

2.1 Position and Duties. Subject to the terms set forth herein, the Company agrees to employ Executive in the position of Executive Vice President and Chief Business Officer. During the Executive's employment, Executive will report to the Chief Executive Officer. Executive shall serve in an employee capacity and shall perform such duties as are assigned to Executive by the Chief Executive Officer and, except as otherwise instructed by the Chief Executive Officer, such other duties as are customarily associated with the position of Executive Vice President and Chief Business Officer. During Executive's employment with the Company, Executive will devote Executive's best efforts and substantially all of Executive's business time and attention (except for vacation periods as set forth herein and reasonable periods of illness or other incapacities permitted by the Company's general employment policies or as otherwise set forth in this Agreement) to the business of the Company.

Both the Company and Executive acknowledge and agree that Executive's employment with the Company is "at-will" and not for any specified period of time, and may be terminated at any time by Executive or the Company, with or without Cause, and with or without prior notice; provided, however, that if Executive's employment with the Company is terminated under circumstances that constitute a Covered Termination, Executive will be eligible to receive certain severance payments and benefits as set forth in Article IV below.

2.4 Indemnification. The Company shall provide for indemnification of the Executive as set forth in the Indemnification Agreement attached hereto as Exhibit A.

ARTICLE III

COMPENSATION

3.1 Base Salary. Commencing January 1, 2019, Executive shall receive for services to be rendered hereunder an annual base salary of $425,000 payable on the regular payroll dates of the Company, subject to increase in the sole discretion of the Compensation Committee of the Board (the "Base Salary").

3.2 Bonus. Executive shall be eligible to earn, for each fiscal year of the Company ending during Executive's employment with the Company, an annual discretionary cash bonus (an “Annual Bonus") targeted at forty-five percent (45%) of Executive's Base Salary. If the Company determines, in its reasonable discretion, that Executive has engaged in any misconduct intended to affect the payment of his/her Annual Bonus, or has otherwise engaged in any act or omission that would constitute Cause for termination of employment, as defined by Section 1.2 of the Agreement, Executive will automatically and immediately forfeit her entire Annual Bonus. If the Annual Bonus has already been paid to Executive, such Annual Bonus will be deemed unearned, and the Company shall have the right to recover the entire amount of the Annual Bonus paid to Executive for the calendar year(s) in which such misconduct or other act or omission constituting Cause occurred. Without limiting the foregoing, any such misconduct or other act or omission constituting Cause will subject Executive to disciplinary action up to and including termination of employment. In addition, any Annual Bonus paid to Executive for the calendar year(s) in which such misconduct or other Cause occurred is subject to recoupment in accordance with The Xxxx-Xxxxx Xxxx Street Reform and Consumer Protection Act and any implementing regulations, any other clawback policy adopted by the Company and any compensation recovery policy otherwise required by applicable laws, regulations or statutes. Recovery by the Company of an Annual Bonus in accordance with this Section shall not constitute an event giving rise to a right by Executive to voluntarily terminate her employment for cause based on such recovery by Company, nor shall it constitute “constructive termination”, or any similar term or circumstance under the Agreement or any other plan or agreement with the Company.

3.3 Equity Compensation. While Executive is actively employed under this Agreement, Executive shall be entitled to participate in one or more of the Company's equity Plans. For each equity grant made under a Plan, Executive will be required to sign a Stock Option Agreement or other equity award agreement in a form to be provided by the Company at the time of grant, and the terms of the equity awards will be governed in all respects by the terms of the Stock Option Agreement or other equity award agreement and the Plan from which the equity award is being granted. Copies of the Plans will be made available to Executive upon request.

3.4 Standard Company Benefits; Vacation. Executive shall be entitled to all rights and benefits for which Executive is eligible under the terms and conditions of the Company's benefit and compensation plans, practices, policies and programs, as in effect from time to time, that are provided by the Company to its senior executives generally. Except as specifically provided herein, nothing in this Agreement is construed or interpreted to provide greater rights, participation, coverage or benefits under such benefit plans or programs provided to executive employees pursuant to the terms and conditions of such benefit plans and programs. Executive will be eligible for vacation accruals in accordance with the Company's current time off policy.

3.5 Housing Allowance and Reimbursement For Relocation Expenses. During Executive’s employment and so long as the performance of Executive’s duties shall, in the Company’s sole discretion, require Executive to reside in New Jersey, the Company will, starting on the commencement date of Executive’s housing lease or rental agreement in New Jersey, provide Executive with reimbursement for out-of-pocket housing costs of not more than $3,000 per month, subject to increase at the sole discretion of the Board or the Compensation Committee of the Board, for costs actually incurred by Executive with respect to housing in New Jersey (the “Housing Allowance”). The Housing Allowance will be reimbursed to Executive upon submission of valid original receipts and any supporting documentation reasonably

3

requested by the Company.  In addition, on the commencement date of Executive’s housing lease or rental agreement in New Jersey, the Company will provide Executive with a one-time relocation allowance in the amount of $10,000, to cover expenses related to relocating to New Jersey (the “Relocation Reimbursement”). The Relocation Reimbursement will be paid in a lump sum in the regular pay period no later than 30 calendar days preceding the commencement of Executive’s housing lease or rental agreement in New Jersey. The Housing Allowance and Relocation Reimbursement will be reported as wages in Executive’s W-2 taxable income.  Any reimbursement pursuant to this Section 3.5 shall be subject to the Company’s policies for reimbursement as may be in place from time-to-time.

ARTICLE IV

SEVERANCE BENEFITS AND RELEASE

4.1 Severance Benefits. If Executive's employment terminates due to a Covered Termination after the date of execution of this Agreement, Executive shall receive:

(i) Payment of Accrued Obligations Upon Termination of Employment. Upon a termination of Executive's employment at any time following the Effective Date, the Company shall pay to Executive in a single lump-sum cash payment as soon as administratively practicable following the date of termination, the aggregate amount of Executive's (A) earned but unpaid Base Salary applicable on the date of termination, and (B) accrued but unpaid vacation pay using the Base Salary rate applicable on the date of termination. In addition, Executive shall be promptly paid for incurred but unreimbursed business expenses upon her submission of such expenses in accordance with the Company's expense reimbursement policies. The amounts set forth in this Section 4.1(i) are collectively referred to as the "Accrued Obligations".

(ii) Severance Upon a Covered Termination. If Executive's employment terminates due to a Covered Termination at any time after the Effective Date, then, in addition to the Accrued Obligations, the Executive will be entitled to the following severance benefits:

(a) Executive shall be paid target Annual Bonus for the fiscal year in which the termination occurs, prorated for the length of service provided during the calendar year through the termination date, payable in a single lump-sum payment within sixty (60) days following the date of termination;

(b) Executive shall be paid an aggregate amount equal to twelve (12) months of Executive's Base Salary in effect on the date of termination, payable to Executive in a single lump-sum amount on the sixtieth (60th) day following the date of termination;

(c) Executive and Executive's covered dependents will be eligible to continue their health care benefit coverage as permitted by COBRA (Internal Revenue Code Section 4980B) at the Company's expense for the lesser of (i) twelve (12) months following the Covered Termination, or (ii) until the Executive and/or Executive's covered dependents are no longer eligible for COBRA (for clarification and as an example, in the event Executive is covered by another health plan, etc.). Thereafter, Executive and Executive's covered dependents shall be entitled to maintain coverage for Executive and Executive's eligible dependents at Executive's own expense for the balance of the period that Executive is entitled to coverage under COBRA; and

(d) any options granted prior or subsequently to the date hereof or other exercisable equity interest in the Company held by Executive, shall remain outstanding and exercisable through the earlier of (i) the second (2^nd) anniversary of the date of termination or (ii) the original expiration date of the option(s) or other equity interest.

4

Notwithstanding the foregoing, if Executive's employment terminates due to a Covered Termination at any time after the Effective Date, Executive will receive the greater of (i) the severance benefits above, or (ii) the severance benefits provided for in the Amended and Restated Severance Plan attached hereto as Exhibit D, which may be amended from time-to-time by the Company at the Company’s sole discretion, that is in effect at the time of termination. For the avoidance of doubt, all amounts payable under this Agreement shall be subject to applicable federal, state, local or foreign tax withholding requirements.

4.2 Parachute Payments. If any payment or benefit Executive would receive in connection with a Change in Control from the Company or otherwise ("Payment") would (i) constitute a "parachute payment" within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the "Excise Tax"), then such Payment shall be reduced to the Reduced Amount. The "Reduced Amount" shall be either (x) the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax or (y) the largest portion, up to and including the total, of the Payment, whichever amount, after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in Executive's receipt, on an after-tax basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting "parachute payments" is necessary so that the Payment equals the Reduced Amount, reduction shall occur in the following order unless Executive elects in writing a different order (provided, however, that such election shall be subject to Company approval): reduction of cash payments; cancellation of accelerated vesting of stock awards; reduction of employee benefits. In the event that acceleration of vesting of stock award compensation is to be reduced, such acceleration of vesting shall be cancelled in the reverse order of the date of grant of Executive's stock awards unless Executive elects in writing a different order for cancellation.

The Company for general audit purposes shall engage a nationally recognized public accounting firm (the "Accounting Firm") to perform the foregoing calculations. The Company shall bear all expenses with respect to the determinations by such Accounting Firm required to be made hereunder. The Accounting Firm engaged to make the determinations hereunder shall provide its calculations, together with detailed supporting documentation, to the Company and Executive within fifteen (15) calendar days after the date on which Executive's right to a Payment is triggered (if requested at that time by the Company or Executive) or such other time as requested by the Company or Executive. If the Accounting Firm determines that no Excise Tax is payable with respect to a Payment, either before or after the application of the Reduced Amount, it shall furnish the Company and Executive with an opinion reasonably acceptable to Executive that no Excise Tax will be imposed with respect to such Payment. Any good faith determinations of the Accounting Firm made hereunder shall be final, binding and conclusive upon the Company and Executive.

4.3 Release. Notwithstanding the foregoing, Executive's right to receive the amounts provided for in Sections 4.l(ii) and 4.2 shall be subject to and conditioned upon Executive's execution and non­revocation of a release of claims in substantially the form attached hereto as Exhibit B (the "Release") (as such form may be modified to take into account changes in the law) within fifty (50) days following the termination date. Such Release shall specifically relate to all of Executive's rights and claims in existence at the time of such execution and shall confirm Executive's obligations under the Proprietary Information Agreement (as defined below). It is understood that Executive has a certain period to consider whether to execute such Release, as set forth in the Release, and Executive may revoke such Release within seven (7) business days after execution. In the event Executive does not execute such Release within the applicable period, or if Executive revokes such Release within the subsequent seven (7) business day period, none of the aforesaid benefits set forth in Sections 4.1(ii), 4.2 and the Change of Control acceleration referenced in Section 3.3 shall be payable to Executive under this Agreement and this Agreement shall be null and void.

5

4.4 Section 409A. Notwithstanding any provision to the contrary in this Agreement, if Executive is deemed by the Company at the time of the Separation from Service to be a "specified employee" for purposes of Section 409A(a)(2)(B)(i) of the Code, to the extent delayed commencement of any portion of the benefits to which Executive is entitled under this Agreement is required in order to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code, such portion of Executive's benefits shall not be provided to Executive prior to the earlier of (a) the expiration of the six-month period measured from the date of Executive's Separation from Service or (b) the date of Executive's death. Upon the first business day following the expiration of the applicable Code Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to this Section 4.4 shall be paid in a lump sum to Executive (or Executive's estate or beneficiaries), and any remaining payments due under the Agreement shall be paid as otherwise provided herein. For purposes of Section 409A of the Code, Executive's right to receive the payments of compensation pursuant to the Agreement shall be treated as a right to receive a series of separate payments and accordingly, each payment shall at all times be considered a separate and distinct payment.

4.5 Mitigation. Executive shall not be required to mitigate damages or the amount of any payment provided under this Agreement by seeking other employment or otherwise, nor shall the amount of any payment provided for under this Agreement be reduced by any compensation earned by Executive as a result of employment by another employer or by any retirement benefits received by Executive after the date of the Covered Termination, or otherwise.

ARTICLE V

PROPRIETARY INFORMATION OBLIGATIONS

5.1 Agreement. Executive agrees to abide by the Proprietary Information and Inventions Agreement attached hereto as Exhibit C (the "Proprietary Information Agreement").

5.2 Remedies. Executive's duties under the Proprietary Information and Inventions Agreement shall survive termination of Executive's employment with the Company and the termination of this Agreement. Executive acknowledges that a remedy at law for any breach or threatened breach by Executive of the provisions of the Proprietary Information and Inventions Agreement would be inadequate, and Executive therefore agrees that the Company shall be entitled to injunctive relief in case of any such breach or threatened breach.

ARTICLE VI

OUTSIDE ACTIVITIES

6.1 No Other Employment. Except with the prior written consent of the Board, Executive shall not during the term of Executive's employment with the Company, undertake or engage in any other employment, occupation or business enterprise.

6.2 No Conflicting Business Interests. During the term of Executive's employment by the Company, except on behalf of the Company, Executive shall not directly or indirectly, whether as an officer, director, stockholder, partner, proprietor, associate, representative, consultant, or in any capacity whatsoever engage in, become financially interested in, be employed by or have any business connection with any other person, corporation, firm, partnership or other entity whatsoever which were known by Executive to compete directly with the Company, throughout the world, in any line of business engaged in (or planned to be engaged in) by the Company; provided, however, that anything above to the contrary notwithstanding, Executive may own, as a passive investor, securities of any competitor corporation, so long as Executive's direct holdings in any one such corporation shall not in the aggregate constitute more than 1% of the voting stock of such corporation.

6

ARTICLE VII NONINTERFERENCE

While employed by the Company, and for one (1) year immediately following the date on which Executive terminates employment or otherwise ceases providing services to the Company, Executive agrees not to interfere with the business of the Company by soliciting or attempting to solicit any employee of the Company to terminate such employee's employment in order to become an employee, consultant or independent contractor to or for any competitor of the Company.

8.3 Severability. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this 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 will not affect any other provision or any other jurisdiction, but this Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provisions had never been contained herein.

8.4 Waiver. If either party should waive any breach of any provisions of this Agreement, they shall not thereby be deemed to have waived any preceding or succeeding breach of the same or any other provision of this Agreement.

8.5 Complete Agreement. This Agreement and Exhibits A, B, C and D hereto constitute the entire agreement between Executive and the Company and are the complete, final, and exclusive embodiment of their agreement with regard to this subject matter (except for the Plans, any successor thereto, or any amendment to the Company's Amended and Restated Severance Plan).

8.6 Counterparts. This Agreement may be executed in separate counterparts, any one of which need not contain signatures of more than one party, but all of which taken together will constitute one and the same Agreement.

8.7 Headings. The headings of the sections hereof are inserted for convenience only and shall not be deemed to constitute a part hereof nor to affect the meaning thereof.

8.8 Successors and Assigns. This Agreement is intended to bind and inure to the benefit of and be enforceable by Executive and the Company, and their respective successors, assigns, heirs, executors and administrators, except that Executive may not assign any of Executive's duties hereunder and Executive may not assign any of Executive's rights hereunder, without the written consent of the Company, which shall not be withheld unreasonably.

However, the Company agrees that this arbitration provision will not apply to any claim, by either Executive or the Company, for injunctive relief. The administrative costs of any arbitration proceeding between Executive and the Company and the fees and costs of the arbitrator shall be borne by the Company.
