NOW THEREFORE, in consideration of the premises and the mutual covenants and agreements set forth herein, the parties hereby agree as follows:

1. Duties and Responsibilities.

(a) The Agreement is hereby amended by deleting Section 3(a) of the Agreement in its entirety and replacing it with the following:

Commencing on the Amendment Effective Date and during the remainder of the Employment Period, Executive shall be employed and serve as the Vice Chairman of the Company.

(b) The Agreement is hereby further amended by deleting the last sentence of Section 3(b) of the Agreement in its entirety and replacing it with the following:

Notwithstanding the foregoing or any other provision of this Agreement, it shall not be a breach or violation of this Agreement for Executive to (i) with the advance approval of the Board or the Governance Committee of the Board (not to be unreasonably withheld), serve on up to two (2) corporate, civic or charitable boards or committees (in addition to those set forth on Schedule I attached hereto, which have previously been approved by the Board), (ii) deliver lectures, fulfill speaking engagements or teach at educational institutions, or (iii) manage personal investments, so long as such activities do not significantly interfere with or significantly detract from the performance of Executive’s responsibilities to the Company in accordance with this Agreement.

2. Compensation and Benefits. The Agreement is hereby further amended by deleting the first sentence of the first bullet of Section 4(b) of the Agreement (entitled “Bonus Opportunity”) in its entirety and replacing it with the following:

For 2017 and each subsequent calendar year during the Employment Period, Executive shall be entitled to receive an Annual Bonus equal to fifty percent (50%) of his then current Annual Base Salary if threshold performance is attained, an Annual Bonus equal to seventy-five percent (75%) of his then current Annual Base Salary (the “Target Bonus”) if target performance is attained, and an Annual Bonus equal to one hundred percent (100%) of his then current Annual Base Salary if performance exceeds the maximum performance level.

3. Termination of Employment. The Agreement is hereby further amended by deleting clause (i) of Section 5(h) of the Agreement in its entirety and replacing it with the following:

the material diminishment of Executive’s authority, duties or responsibilities (as shall be established by the Board as soon as practicable following the Amendment Effective Date), it being understood that during a Change in Control Period, Good Reason shall be deemed to have occurred if Executive is not the Vice Chairman of the ultimate parent following the Change in Control;

4. Severance Benefits upon Termination without Cause or Resignation for Good Reason during the Term.

(a) The Agreement is hereby further amended by deleting the proviso to Section 7(a) of the Agreement in its entirety.

Notwithstanding anything to the contrary in Section 5(a) of the 2016 Performance-Based Long-Term Incentive Plan Award Agreement, dated as of March 8, 2016, between the Company and Executive (the “Performance-Based LTIP Award Agreement”) and Section 5(a) of the 2016 Time-Based Long-Term Incentive Plan Award Agreement, dated as of March 8, 2016, between the Company and Executive (the “Time-Based LTIP Award Agreement”), the provisions of this Section 7(a) shall supersede the provisions of Sections 5(b)(i), 5(b)(ii) and 5(b)(iii) of the Performance-Based LTIP Award Agreement and Section 5(b)(ii) and 5(b)(v) of the Time-Based LTIP Award Agreement, as applicable, and shall exclusively govern the treatment of all of Executive’s Award LTIP Units (as defined in the Performance-Based LTIP Award Agreement or the Time-Based LTIP Award Agreement, as applicable) in the event that during the Term (i) the Company terminates Executive’s employment for any reason other than Cause or Disability or (ii) Executive resigns for Good Reason. The foregoing principles shall also apply to any LTIP awards granted in 2017 and 2018, and the award agreements for such awards shall reflect such treatment.

5. Non-compete. The Agreement is hereby further amended by deleting Section 13(a) of the Agreement in its entirety and replacing it with the following:

During the Employment Period, and for a one (1) year period thereafter in the event Executive’s employment is terminated under circumstances in which he is entitled to receive and is receiving the benefits provided in Sections 6, 7, 8(b) or 8(c) hereof, Executive shall not, directly or indirectly, within Hudson County in the State of New Jersey, engage in, or own, invest in, manage or control any venture or enterprise primarily engaged in any office-service, flex, or office property development or acquisition activities that are competitive with the activities of the Company. Nothing herein shall prohibit Executive from being a passive owner of not more than five percent (5%) of the outstanding stock of any class of securities of a company or other entity engaged in such business that is publicly traded, so long as Executive has no active participation in the business of such Company or other entity.
