THIS STOCK UNIT AWARD AGREEMENT (the “Agreement”), effective as of the ____ day of January, 2016 (the “Grant Date”), governs an award granted by DUPONT FABROS TECHNOLOGY, INC., a Maryland corporation (the “Company”), of stock units for shares of the common stock of the Company, par value, $0.001 per share (“Common Stock”), to __________________________ (the “Participant”), in accordance with and subject to the provisions of the Company’s 2011 Equity Incentive Plan (the “Plan”). A copy of the Plan has been made available to the Participant. Capitalized terms used, but not defined, in this Agreement shall have the meaning given such terms in the Plan.

1.    Grant of Awards. In accordance with the Plan, and effective as of the Grant Date, the Company hereby grants to the Participant, subject to the terms and conditions of the Plan and this Agreement, an award of _______________ (______) stock units (the “Stock Unit Award,” with the number set forth in this sentence being the “Target Award”).

2.    Vesting. The Participant’s interest in the stock units covered by the Stock Unit Award shall become vested as provided in this Section.

(a)    Company Total Shareholder Return Compared to RMS Return. One-half of the Participant’s interest in the stock units covered by the Stock Unit Award (the “RMS Return Target Award”) shall become vested as provided in the schedule below, if (i) the Participant remains in continuous Service from the Grant Date until the Vesting Date, and (ii) the Company’s Total Shareholder Return for the Performance Period, meets or exceeds the RMS Return for the Performance Period. The specific number of stock units that may vest with respect to the RMS Return Target Award shall be determined in accordance with the following:

In the event that the Performance Level is between the “Target” and “Maximum” levels (as set forth in the table above), the number of stock units that will vest with respect to the RMS Return Target Award will be interpolated on a straight line basis, between 100% and 300% of the RMS Return Target Award. If at the end of the Performance Period, none of the stock units covered by the Stock Unit Award related to RMS Return Target Award have vested in accordance with the criteria set forth above, the portion of the Stock Unit Award related to RMS Return Target Award will immediately lapse in its entirety. Except as provided in this Agreement, any stock units covered by the portion of the Stock Unit Award related to RMS Return Target Award that are not vested and nonforfeitable on or before the date of the Participant’s termination of Service shall be forfeited on the date that such Service terminates.

Notwithstanding anything in this Agreement to the contrary, if the Total Shareholder Return for the Performance Period is negative, the calculated payouts will be reduced by 50%. By way of example, if the Total Shareholder Return for the Performance Period was negative 5.0%, while the RMS Return for the Performance Period was negative 8.0%, then the Participant will vest in a number of stock units equal to 150% of the RMS Return Target Award.

(b)    Company Total Shareholder Return Compared to Data Center Index Return. One-half of the Participant’s interest in the stock units covered by the Stock Unit Award (the “Data Center Index Return Target Award”) shall become vested as provided in the schedule below, if (i) the Participant remains in continuous Service from the Grant Date until the Vesting Date, and (ii) the Company’s Total Shareholder Return for the Performance Period, meets or exceeds the Data Center Index Return for the Performance Period. The specific number of stock units that may vest with respect to the Data Center Index Return Target Award shall be determined in accordance with the following:

In the event that the Performance Level is between the “Target” and “Maximum” levels (as set forth in the table above), the number of stock units that will vest with respect to the Data Center Index Return Target Award will be interpolated on a straight line basis, between 100% and 300% of the Data Center Index Return Target Award. If at the end of the Performance Period, none of the stock units covered by the Stock Unit Award related to Data Center Index Return Target Award have vested in accordance with the criteria set forth above, the portion of the Stock Unit Award related to Data Center Index Return Target Award will immediately lapse in its entirety. Except as provided in this Agreement, any stock units covered by the portion of the Stock Unit Award related to Data Center Index Return Target Award that are not vested and nonforfeitable on or before the date of the Participant’s termination of Service shall be forfeited on the date that such Service terminates.

Notwithstanding anything in this Agreement to the contrary, if the Total Shareholder Return for the Performance Period is negative, the calculated payouts will be reduced by 50%. By way of example, if the Total Shareholder Return for the Performance Period was negative 5.0%, while the Data Center Index Return for the Performance Period was negative 8.0%, then the Participant will vest in a number of stock units equal to 150% of the Data Center Index Return Target Award.

7.    Transferability. Stock units covered by the Stock Unit Award that have not become vested and nonforfeitable under this Agreement cannot be transferred.

8.    Stockholder Rights. The Participant does not have any of the rights of a stockholder with respect to any unvested stock unit, including voting and dividend rights.

9.    Withholding. The Participant must make acceptable arrangements to pay any withholding or other taxes that may be due as a result of the vesting or receipt of the stock units or the shares of Common Stock.

Unless otherwise determined by the Company, the Company shall withhold the delivery of vested shares of Common Stock otherwise deliverable under this Agreement to meet such obligations. The shares of Stock so withheld shall have an aggregate Fair Market Value equal to such withholding obligations.

10.    No Right to Continued Employment. The grant of the Stock Unit Award does not give the Participant any right with respect to continuance of Service, nor shall it interfere in any way with the right of the Company or an Affiliate to terminate his Service at any time.

11.    Adjustments. Notwithstanding anything herein to the contrary, the Committee, in its sole discretion, may make appropriate adjustments to the Target Award and any of the metrics set forth in Section 2 in connection with or as a result of any of the following events that have occurred after the Grant Date: reorganization, recapitalization, reclassification, stock dividend (after taking into consideration any payments to be made pursuant to Section 8), stock split, reverse stock split or other similar changes in the Common Stock, if the outstanding

In addition, notwithstanding anything herein to the contrary, the Committee, in its sole discretion, may make appropriate adjustments to the MSCI US REIT Index (RMS), or the RMS Return, or the securities that comprise the Data Center Index, or the Data Center Index Return, to account for any changes to such index, including, without limitation, any of the changes described above in this section.
