Item 1.01. Entry into a Material Definitive Agreement.

The information set forth under Item 5.02 of this Current Report on Form 8-K regarding the restricted stock unit award agreements described under Item 5.02 is hereby incorporated by reference under this Item 1.01.

Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On March 3, 2016, City Office REIT, Inc. (the “Company”) entered into restricted stock unit award agreements with its executive officers as listed below. These restricted stock unit award agreements were approved by the Company’s Board of Directors (the “Board”), as recommended by the Compensation Committee of the Board (the “Compensation Committee”), at meetings that occurred on March 2, 2016, where the Compensation Committee recommended and the Board approved the restricted stock units pursuant to the Company’s 2014 Equity Incentive Plan (the “Plan”) as indicated in the table below. The awards were made pursuant to restricted stock unit award agreements between the Company and each of its executive officers, subject to vesting over a three-year period. Restricted stock units vest in three equal installments on each of the first three anniversaries of the grant date and shall vest in full upon the termination of employment without Cause (as defined in the form of award agreement). If earned, the restricted stock units will be settled in the form of shares of the Company’s common stock, par value $0.01 per share (“Common Stock”), pursuant to the Plan, or if approved by the Compensation Committee, in cash of equivalent value. Restricted stock units do not entitle the recipient the rights of a holder of Common Stock until shares are issued in settlement of the vested units. As dividends are paid on the Company’s common stock, additional restricted stock units will be issued covering that number of shares of Common Stock with a value equivalent to the total dividends that would be paid on the number of shares underlying the restricted stock units.

The following table sets forth the executive officers who received the restricted stock unit awards on March 3, 2016:

The foregoing description of the restricted stock unit award agreements does not purport to be complete and is qualified in its entirety by the full text of such agreement filed as Exhibit 10.1 hereto and incorporated by reference herein.
