Exhibit 10.15

PERFORMANCE-BASED LTIP UNIT AGREEMENT FOR CHAIRMAN OF THE BOARD

This Performance-Based LTIP Unit Agreement (this “Agreement”) is made effective as of the Grant Date set forth on the Schedule to Performance-Based LTIP Unit Agreement (the “Schedule”) attached hereto (the “Grant Date”), between the recipient set forth on the Schedule attached hereto (the “Recipient”), EQC Operating Trust (the “Trust”) and Equity Commonwealth (the “Company”).

In consideration of the mutual promises and covenants contained in this Agreement, and for other valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1.Grant of LTIP Units. Subject to the terms and conditions hereinafter set forth, the terms and conditions of the Equity Commonwealth 2015 Omnibus Incentive Plan, as it may be amended from time to time (the “Plan”), and the terms and conditions of the Declaration of Trust of EQC Operating Trust, as it may be amended from time to time (the “Declaration”), the Company and the Trust together hereby grant to the Recipient, effective as of the Grant Date, an Award of OP Units under the Plan in the form of LTIP Units (as defined in the Declaration). The number of LTIP Units granted to the Recipient hereunder is set forth on the Schedule attached hereto. The LTIP Units so granted are hereinafter referred to as the “Performance-Based LTIP Units.” Except as otherwise set forth herein, the Performance-Based LTIP Units have the rights, voting powers, restrictions, limitations as to distributions, qualifications, and terms and conditions of redemption and conversion as set forth in the Declaration. Upon the close of business on the thirtieth (30^th) business day following the Grant Date (the “Final Acceptance Date”), if the terms and conditions of the Performance-Based LTIP Units set forth in this Agreement, in the Declaration, and in the Plan are accepted, and if the Recipient has paid to the Trust a Capital Contribution (as defined in the Declaration) per Performance-Based LTIP Unit in the amount, if any, set forth on the Schedule attached hereto, the Recipient shall receive the number of Performance-Based LTIP Units specified on the Schedule attached hereto, effective as of the Grant Date, subject to the vesting, forfeiture, and other conditions set forth in this Agreement, in the Declaration, and in the Plan. For the avoidance of doubt, the Performance-Based LTIP Units granted to the Recipient hereunder constitute OP Units under the Plan for all purposes of the Plan. The number of Performance-Based LTIP Units that the Recipient actually earns for the Performance Period will be determined by the level of achievement of the Performance Criteria in accordance with Exhibit A attached hereto, and may be higher or lower than the number of Performance-Based LTIP Units granted to the Recipient. The initial Economic Capital Account Balance (as defined in the Declaration) per Performance-Based LTIP Unit is set forth on the Schedule attached hereto. Capitalized terms that are used but not defined herein have the meanings ascribed to them in the Plan.

2. Acceptance of Agreement. Upon the close of business on the Final Acceptance Date, if the terms and conditions of the Performance-Based LTIP Units set forth in this Agreement and in the Plan are accepted by the Recipient, and if the Recipient has paid to the Trust the Capital Contribution, if any, set forth on the Schedule attached hereto, then the Recipient, unless he or she is already a Unitholder (as defined in the Declaration), shall automatically and without further action on the Recipient’s part, be deemed to be admitted as a Unitholder of the Trust, as of the Grant Date, with beneficial ownership of the Performance-Based LTIP Units. Thereupon, the Recipient shall have all the rights of a Unitholder of the Trust with respect to the Performance-Based LTIP Units, as set forth in the Declaration, subject, however, to the restrictions and conditions specified herein, in the Declaration, and in the Plan. The Recipient shall be designated as an Additional Unitholder (as defined in the Declaration) and shall be bound by the terms and provisions of the Declaration, including the power of attorney set forth in Section 14.11 of Annex A to the Declaration. In order to confirm receipt of this

Agreement, the Recipient must execute this Agreement, which execution shall be deemed to constitute execution of the Declaration.

3. Performance Period. For purposes of this Agreement, the term “Performance Period” shall be the period commencing on January 29, 2018 and ending on January 29, 2021.

4. Performance Criteria.

(a) The number of Performance-Based LTIP Units earned by the Recipient for the Performance Period (the “Earned Performance-Based LTIP Units”) shall be determined at the end of the Performance Period based on the level of achievement of the Performance Criteria in accordance with Exhibit A. All determinations of whether and to what extent the Performance Criteria has been achieved, the number of Performance-Based LTIP Units earned by the Recipient, and all other matters related to this Section 4 shall be made by the Committee in its sole discretion. Any Performance-Based LTIP Units that do not become Earned Performance-Based LTIP Units at the end of the Performance Period, as determined by the Committee in its sole discretion, shall be immediately forfeited by the Recipient.

(b) Following the completion of the Performance Period, the Committee shall determine (i) whether, and to what extent, the Performance Criteria has been achieved, and (ii) the number of Performance-Based LTIP Units that shall be deemed Earned Performance-Based LTIP Units, if any. Such determination shall be final, conclusive and binding on the Recipient, and on all other persons, to the maximum extent permitted by law.

5. Vesting; Forfeiture.

(a) 50% of the Earned Performance-Based LTIP Units shall vest on the date that the Committee determines the achievement of the Performance Criteria in accordance with Section 4(a) hereof, subject to the Recipient’s continued service with the Company through such date.

(b) 50% of the Earned Performance-Based LTIP Units shall vest in February of the calendar year during which the fourth anniversary of the Grant Date occurs, either on (i) the date on which the Committee meets to determine the level of achievement of the performance criteria with respect to any performance-based equity awards or, (ii) if there are no such awards for which performance is required to be measured during such calendar year, as determined by the Committee, the first date on which the Committee meets or takes an action by unanimous written consent, in each case subject to the Recipient’s continued service with the Company through the applicable date.

(c) Subject to Section 6 hereof, in the event the Recipient ceases to render services to the Company as a Trustee, all unvested Performance-Based LTIP Units shall be forfeited by the Recipient as of the date the Recipient ceases to render such services.

6. Termination of Service; Change in Control.

(a) If, during the Performance Period, the Recipient’s service as a Trustee terminates due to the Recipient’s death, then the number of Performance-Based LTIP Units that are earned by the Recipient shall be determined at the end of the Performance Period in accordance with Section 4 hereof, and the Recipient’s Earned Performance-Based LTIP Units, if any, shall become vested as of the date that the Committee determines the achievement of the Performance Criteria in accordance with Section 4(a) hereof on a pro rata basis, determined based on (x) the number of days that have elapsed from the beginning of the Performance Period through the date of the Recipient’s death, compared to (y) the total number of days during the period commencing on January 29, 2018 and ending on January 29, 2022. Notwithstanding the foregoing, if, during the Performance Period and

within twelve (12) months after a Change in Control in which the Performance-Based LTIP Units are assumed by the acquirer or surviving entity in the Change in Control transaction, the Recipient dies or is no longer Chairman of the Board, then any such Earned Performance-Based LTIP Units shall become fully vested as of the date that the Committee determines the achievement of the Performance Criteria in accordance with Section 4(a) hereof. With respect to Earned Performance-Based LTIP Units held by the Recipient for which the Performance Period is complete but for which the additional vesting period is incomplete, any restrictions on the Earned Performance-Based LTIP Units shall lapse and such Earned Performance-Based LTIP Units shall automatically become fully vested as of (i) the date the Recipient is no longer Chairman of the Board, provided such date occurs within twelve (12) months after a Change in Control in which the LTIP Units are assumed by the acquirer or surviving entity in the Change in Control transaction, or (2) the date of the Recipient’s death.

(b) If, during the Performance Period, a Change in Control occurs while the Recipient is a Trustee of the Company, and the Performance-Based LTIP Units are not assumed by the acquirer or surviving entity in the Change in Control transaction, then the Recipient’s Performance-Based LTIP Units shall be deemed earned based on the actual level of achievement of the Performance Criteria measured as of the date of the Change in Control, as determined by the Committee based on a then forty (40) day trailing average price per share of Stock. Any such Earned Performance-Based LTIP Units shall be fully vested. With respect to Earned Performance-Based LTIP Units held by the Recipient for which the Performance Period is complete but for which the additional vesting period is incomplete, any restrictions on the Earned Performance-Based LTIP Units shall lapse and such Earned Performance-Based LTIP Units shall automatically become fully vested as of the date of the Change in Control. Notwithstanding the foregoing, to the extent necessary for the Recipient to avoid taxes and/or penalties under Section 409A of the Code, a Change in Control shall not be deemed to occur unless it constitutes a “change in control event” within the meaning of Section 1.409A-3(i)(5) of the Treasury Regulations promulgated under Section 409A of the Code.

7. Distributions. The Recipient shall be entitled to distributions on the Performance-Based LTIP Units in accordance with the terms and provisions of the Declaration. For purposes of the Declaration, the Distribution Participation Date (as defined in the Declaration) shall not occur with respect to the Performance-Based LTIP Units covered by this Agreement unless and until such Performance-Based LTIP Units become Earned Performance-Based LTIP Units. With respect to any Performance-Based LTIP Units that become Earned Performance-Based LTIP Units, the Distribution Participation Date shall occur on the date that the Committee determines the achievement of the Performance Criteria in accordance with Section 4 hereof. For purposes of the Declaration, a Special LTIP Unit Distribution (as defined in the Declaration) shall be payable with respect to the Earned Performance-Based LTIP Units, if any, covered by this Agreement. The Recipient’s LTIP Unit Sharing Percentage (as defined in the Declaration) for each Earned Performance-Based LTIP Unit is set forth on the Schedule attached hereto.

8. Conversion. The Performance-Based LTIP Units shall be subject to conversion into Class A Units (as defined in the Declaration) in accordance with the terms and provisions of the Declaration.

9. Transferability of Performance-Based LTIP Units. The Performance-Based LTIP Units shall be subject to the restrictions on transfer set forth in the Declaration and the Plan. Following any transfer of the Performance-Based LTIP Units, the Performance-Based LTIP Units shall continue to be subject to the same terms and conditions as were applicable immediately prior to such transfer and the provisions of Section 6 hereof relating to termination of service shall continue to be applied with respect to the original Recipient of the Performance-Based LTIP Units. Notwithstanding any transfer made by the Recipient pursuant to this Section 9, the Recipient (or the Recipient’s beneficiary or estate, as applicable) shall be responsible for all income and other taxes associated with the Performance-Based LTIP Units.

10. Legends. The records of the Trust evidencing the Performance-Based LTIP Units shall bear an appropriate legend, as determined by the Trust in its sole discretion, to the effect that such Performance-Based LTIP Units are subject to restrictions as set forth in this Agreement, in the Plan, and in the Declaration.

11. Tax Withholding. The Company and the Trust shall have the right to withhold or cause to be withheld from any compensation paid to the Recipient pursuant to the Plan, the amount of any required withholding taxes in respect of the Performance-Based LTIP Units and to take all such other action as the Company and the Trust deem necessary to satisfy all obligations for the payment of such withholding taxes. The Recipient agrees that if the amount payable to the Recipient by the Company in the ordinary course is insufficient to pay such withholding taxes, then the Recipient shall, upon the request of the Company or the Trust, pay to the Company or the Trust, as applicable, an amount sufficient to satisfy its tax withholding obligations.

12. Investment Representation. The Recipient hereby makes the covenants, representations, and warranties set forth on Exhibit B attached hereto as of the date of acceptance of this Agreement and on each applicable vesting date, as set forth above, to the Company and the Trust.

Exhibit A

Performance Criteria

Performance Criteria: The Performance-Based LTIP Units shall be earned based on the Company’s total shareholder return (“TSR”) for the Performance Period relative to the TSRs of the companies that comprise the NAREIT Office Index for the Performance Period, as set forth in the table below. Depending on the Company’s TSR relative to the TSRs of the companies that comprise the NAREIT Office Index for the Performance Period, the Recipient may earn between 0% and 249.25% of the Performance-Based LTIP Units.



Performance Criteria: Company Performance vs. NAREIT Office Index Performance	% of Performance-Based LTIP Units Earned
90^th Percentile and Above (Maximum Award)	249.25	%
80^th Percentile	211.87	%
70^th Percentile	174.48	%
60^th Percentile	137.09	%
50^th Percentile (Target Award)	100.00	%
40^th Percentile	68.55	%
30^th Percentile	37.39	%
25^th Percentile (Threshold Award)	25.37	%
Below 25^th Percentile	0.00	%

Absolute Modifier: If the Company’s total TSR for the Performance Period is negative, any Performance-Based LTIP Units deemed earned based on the table above shall be reduced by 25%.

Interpolation: To the extent performance falls between two levels in the table above, linear interpolation shall apply in determining the percentage of the Performance-Based LTIP Units that are earned.

TSR Calculation: TSR performance shall be calculated as the compounded annual growth rate, expressed as a percentage (rounded to the nearest tenth of a percent (0.1%)), in the value per share during the Performance Period due to the appreciation in the price per share and dividends paid during the Performance Period, assuming dividends are reinvested. “D” is the amount of dividends paid to a shareholder of record of the Company with respect to one share during the Performance Period. The absolute TSR percentage is calculated pursuant to the formula set forth below.

Cumulative TSR = ((1+TSR Year 1)*(1+TSR Year 2)*(1+TSR Year 3))-1

=(1+Cumulative TSR)^(1/3)-1

TSR shall be calculated as follows:

(Ending Share Price+D)/Beginning Share Price-1

The performance for the companies comprising the NAREIT Office Index shall be calculated in the same manner as described above and the difference between the absolute TSR of the Company and the average

absolute TSR for the companies within the NAREIT Office Index, expressed in terms of relative percentile ranking, shall be applied to the matrix set forth above. Only companies that are public throughout the entire Performance Period shall be included for purposes of calculating the relative TSR comparison (i.e., companies that may become acquired, have an initial public offering, etc. during the Performance Period shall be excluded from the calculation altogether). For purposes of the calculation above, the Beginning Share Price for TSR Year 1 shall be the closing stock price on the Grant Date, the Beginning Share Price for TSR Year 2 shall be the Ending Share Price for TSR Year 1, and the Beginning Share Price for TSR Year 3 shall be the Ending Share Price for TSR Year 2. For purposes of the calculation above, the Ending Share Price for TSR Year 1 shall be the closing stock price as of the last trading day of TSR Year 1, the Ending Share Price for TSR Year 2 shall be the closing stock price as of the last trading day of TSR Year 2, and the Ending Share Price for TSR Year 3 shall be based on a 40-day trailing average closing stock price as of the last trading day of TSR Year 3.
