	 	Re:	EMPLOYMENT TERMS 

 Dear Mr. Power: 

Digital Realty Trust, Inc. (the “REIT”) and DLR LLC (the “Employer” and together with the REIT, the
“Company”) are pleased to offer you employment with the REIT and the Employer on the terms and conditions set forth in this letter (this “Agreement”), effective as of a date mutually agreed to by you and the
Company, but in no event later than July 16, 2015 (such date, the “Effective Date”).  
 1. TERM.
Subject to the provisions for earlier termination hereinafter provided, your employment hereunder shall be for a term (the “Term”) commencing on the Effective Date and ending on the third (3rd) anniversary of the Effective Date (the “Initial Termination Date”). If not previously terminated, the Term shall automatically be extended for one additional year on the
Initial Termination Date, unless either you or the Company elect not to so extend the Term by notifying the other party, in writing, of such election not less than sixty (60) days prior to the Initial Termination Date. 

2. POSITION, DUTIES AND RESPONSIBILITIES. During the Term, the Company will employ you, and you agree to be employed by the
Company, as Chief Financial Officer of the REIT and the Employer. In the capacity of Chief Financial Officer, you will have such duties and responsibilities as are normally associated with such position and will devote your full business time and
attention to serving the Company in such position. Your duties may be changed from time to time by the Company, consistent with your position. You will report to the Chief Executive Officer of the Company. You will work full-time at our principal
offices located in San Francisco, California (or such other location in the San Francisco greater metropolitan area as the Company may utilize as its principal offices), except for travel to other locations as may be necessary to fulfill your
responsibilities. At the Company’s request, you will serve the Company and/or its subsidiaries and affiliates in other offices and capacities in addition to the foregoing. In the event that you serve in any one or more of such additional
capacities, your compensation will not be increased beyond that specified in this Agreement. In addition, in the event your service in one or more of such additional capacities is terminated, your compensation, as specified in this Agreement, will
not be diminished or reduced in any manner as a result of such termination for so long as you otherwise remain employed under the terms of this Agreement. 

3. BASE COMPENSATION. During the Term, the Company will pay you a base salary of $425,000 per year, less payroll deductions and
all required withholdings, payable in  

 
accordance with the Company’s normal payroll practices and prorated for any partial month of employment. Your annual base salary may be increased, but not decreased, by the Compensation
Committee of the Board of Directors of the REIT (the “Compensation Committee”) in its discretion pursuant to the Company’s policies as in effect from time to time, and such increased amount thereafter will be your base salary
per year for purposes of this Agreement. 
 4. ANNUAL BONUS. In addition to the base salary set forth above, during the
Term, you will be eligible to participate in the Company’s incentive bonus plan applicable to similarly situated executives of the Company. The amount of your annual bonus will be based on the attainment of performance criteria established and
evaluated by the Company in accordance with the terms of such bonus plan as in effect from time to time, provided that, subject to the terms of such bonus plan and attainment of performance criteria established by the Company, your target and
maximum annual bonus shall be one hundred percent (100%) and one hundred fifty percent (150%), respectively, of your base salary for such year. Any annual bonus that becomes payable to you is intended to satisfy the short-term deferral
exemption under Treasury Regulation Section 1.409A-1(b)(4) and shall be made not later than the last day of the applicable two and one-half (2  1⁄2) month
“short-term deferral period” with respect to such annual bonus, within the meaning of Treasury Regulation Section 1.409A-1(b)(4). 

5. BENEFITS AND VACATION. During the Term, you will be eligible to participate in all incentive, savings and retirement plans,
practices, policies and programs maintained or sponsored by the Company from time to time which are applicable to other similarly situated executives of the Company, subject to the terms and conditions thereof. During the Term, you will also be
eligible for standard benefits, such as medical insurance, paid time-off and holidays to the extent applicable generally to other similarly situated executives of the Company, subject to the terms and conditions of the applicable Company plans or
policies. 
 6. RELOCATION BENEFITS. You will be entitled to receive reimbursement for the costs of all reasonable
relocation expenses (not to exceed $250,000, net of any applicable taxes) incurred by you through the end of calendar year 2016 in connection with your relocation to the San Francisco, California area in accordance with the expense reimbursement
policies and practices of the Company that are applicable to other similarly situated executives of the Company (the “Relocation Expenses”). In addition, for a period of up to four (4) weeks, you will be entitled to receive
reimbursement for the reasonable costs of your lodging, temporary living, commuting to and from San Francisco, California and/or house hunting expenses in the San Francisco, California area in accordance with the expense reimbursement policies and
practices of the Company that are applicable to other similarly situated executives of the Company (the “Temporary Housing Expenses”). As soon as administratively practicable following your relocation (but in no event more than
thirty (30) days thereafter), subject to and conditioned upon your continued employment through the applicable payment date, the Company will pay you an amount in cash equal to $35,417, subject to applicable federal, state and local tax
withholding, and other authorized deductions (the “Relocation Payment” and, together with the Relocation Expenses and the Temporary Housing Expenses, the “Relocation Benefits”). Should you voluntarily resign within
one year from the date of your final relocation to the San Francisco, California area, you will be required to repay the Company the full amount of Relocation Benefits actually received by you.

 7. LONG-TERM INCENTIVE AWARDS. Subject to approval by the Compensation Committee,
the REIT agrees to grant to you in your capacity as an employee of the Company and in consideration of your provision of services to the Company, (i) an award of profits interest units of Digital Realty Trust, L.P. (the “Operating
Partnership”) which will be subject to time-based vesting equivalent to approximately $1,000,000 and (ii) an award of Class D profits interest units of the Operating Partnership which will be subject to performance-based vesting
equivalent to approximately $1,250,000 (collectively, the “Grants”). Alternatively, if you do not qualify as an accredited investor or if you otherwise so elect, you will receive (i) a restricted stock unit grant subject
to time-based vesting in lieu of profits interest units and (ii) a restricted stock unit grant subject to performance-based vesting in lieu of the Class D profits interest units. The number of profits interest units and Class D profits
interest units (or, if applicable, restricted stock units) to be issued will be determined on the date of Compensation Committee approval or such other day as the Compensation Committee may determine. Subject to your continued employment with the
Company, twenty-five percent (25%) of the profits interest units (or, if applicable, restricted stock units) subject to the time-based Grant shall vest on each of the first four anniversaries of the Effective Date, and the performance-based
Grant shall vest in accordance with a vesting schedule approved by the Compensation Committee. Consistent with the foregoing, the terms and conditions of the Grants shall be set forth in profits interest unit and Class D profits interest units
agreements (or, if applicable, restricted stock unit Agreements) which will be provided to you for acceptance and as evidence of such Grants as soon as administratively possible following the grant date.  

8. TERMINATION OF EMPLOYMENT. 

(a) Without Cause or for Good Reason. Subject to Section 8(g) below, in the event of a termination of your employment
during the Term by the Company without Cause or by you for Good Reason (each as defined below), then, in addition to any other accrued amounts payable to you through the date of termination of your employment (such date, or the date of your death if
applicable under Section 8(c) below, the “Termination Date”), the Company will pay and provide you with the following payments and benefits: 

(i) payable within thirty (30) days after your Termination Date (with the exact payment date to be determined by the Company in its
discretion), a lump-sum severance payment in an amount equal to the sum of (x) one (1.0) (the “Severance Multiple”) times the sum of (A) your annual base salary as in effect on the Termination Date, plus (B) your
target annual bonus for the fiscal year in which the Termination Date occurs (in the case of both (A) and (B), without giving effect to any reduction which constitutes Good Reason), (y) the Stub Year Bonus, plus (z) the Prior Year
Bonus, if any; 
 (ii) for a period commencing on the Termination Date and ending on the earlier of (x) the twelve (12)-month
anniversary of the Termination Date or (y) the date on which you become eligible to receive comparable group health insurance coverage under a subsequent employer’s plans, the Company shall continue to provide you and your eligible family
members with group health insurance coverage at least equal to that which would have 

  
 3 

 
been provided to you if your employment had not been terminated (including, in the discretion of the Company, by purchasing COBRA coverage for you and your eligible family members);
provided, however, that if (A) any plan pursuant to which the Company is providing such coverage is not, or ceases prior to the expiration of the period of continuation coverage to be, exempt from the application of
Section 409A of the Code (as defined below) under Treasury Regulation Section 1.409A-1(a)(5), or (B) the Company is otherwise unable to continue to cover you under its group health plans or doing so would jeopardize the tax-qualified
status of such plans, then, in either case, an amount equal to the monthly plan premium payment shall thereafter be paid to you as currently taxable compensation in substantially equal monthly installments over the continuation period (or the
remaining portion thereof); 
 (iii) for a period commencing on the Termination Date and ending on the twelve (12)-month anniversary of the
Termination Date, the Company shall, at its sole expense and on an as-incurred basis, provide you with outplacement counseling services directly related to your termination of employment with the Company, the provider of which shall be selected by
the Company; and 
 (iv) to the extent that any outstanding Company equity-based awards issued to you under the Company’s equity
incentive plans are subject to vesting based on continued employment or the lapse of time, such awards shall become vested and exercisable immediately prior to the Termination Date. The vesting of any awards that are subject to vesting based on the
satisfaction of performance goals, including, without limitation, any performance-based profits interest units of the Operating Partnership and other “outperformance awards” issued to you, shall be governed by the terms of the award
agreements evidencing such awards. For purposes of clarification, except as otherwise provided under any award agreements relating to such awards, the terms set forth in this Agreement, including this Section 8, are intended to be in addition
to (and not in lieu of) the vesting and acceleration features related to such stock options and other equity-based awards (including profits interest units of the Operating Partnership and other “outperformance awards”) held by you and
included elsewhere, including in any award agreements related to such awards, and the vesting and acceleration terms hereof shall be applicable only to the extent they result in additional acceleration or vesting of such stock options and other
equity-based awards held by you. 
 (b) Change in Control. Subject to Section 8(g) below, in the event that a Change in
Control (as defined in the Digital Realty Trust, Inc., Digital Services, Inc. and Digital Realty Trust, L.P. 2014 Incentive Award Plan or any successor incentive plan) occurs during the Term and, on the date of or within one year after such Change
in Control, you incur a termination of employment by the Company without Cause or by you for Good Reason (each as defined below), then, in addition to any other accrued amounts payable to you through the Termination Date, you shall be entitled to
the payments and benefits provided in Section 8(a) hereof, subject to the terms and conditions thereof, except that, for purposes of this Section 8(b), the Severance Multiple shall be equal to two (2.0). 

(c) Death or Disability. Subject to Section 8(g) below, and notwithstanding anything to the contrary contained herein, in
the event of a termination of your employment during the Term by reason of your death or Disability (as defined below), then, in addition to any other accrued amounts payable to you through the Termination Date, the Company will pay and provide you
(or your estate or legal representative) with the following payments and benefits: 

  
 4 

 (i) payable within thirty (30) days after your Termination Date (with the exact payment
date to be determined by the Company in its discretion), a lump-sum severance payment in an amount equal to the sum of (w) your annual base salary as in effect on the Termination Date, (x) your target annual bonus for the fiscal year in
which the Termination Date occurs, (y) the Stub Year Bonus, plus (z) the Prior Year Bonus, if any; and 
 (ii) to the extent that
any outstanding Company equity-based awards issued to you under the Company’s equity incentive plans are subject to vesting based on continued employment or the lapse of time, such awards shall become vested and exercisable immediately prior to
the Termination Date. The vesting of any awards that are subject to vesting based on the satisfaction of performance goals, including, without limitation, any performance-based profits interest units of the Operating Partnership and other
“outperformance awards” issued to you, shall be governed by the terms of the award agreements evidencing such awards. 
 (d)
Expiration; Non-renewal. Notwithstanding anything contained herein, in no event shall the expiration of the Term set forth in Section 1 above or the Company’s election not to renew or extend the Term or your employment with
the Company constitute a termination your employment by the Company without Cause. 
 (e) Termination of Offices and
Directorships. Upon a termination of your employment for any reason, except to the extent otherwise determined by the Board of Directors of the REIT (the “Board”) in its sole discretion, you shall be deemed to have resigned
from all offices, directorships and other employment positions, if any, then held with the Company or any member of the Digital Group (as defined below), and you agree that you shall take all actions reasonably requested by the Company to effectuate
the foregoing. 
 (f) Potential Six-Month Delay. Notwithstanding anything to the contrary in this Agreement, no compensation
or benefits, including without limitation any termination payments or benefits payable under this Section 8, shall be paid to you prior to the expiration of the six (6)-month period following your “separation from service” from the
Company (within the meaning of Section 409A(a)(2)(A)(i) of the Internal Revenue Code of 1986, as amended (the “Code”)) to the extent that the Company determines that paying such amounts at the time or times indicated in this
Agreement would be a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code. If the payment of any such amounts is delayed as a result of the previous sentence, then on the first business day following the end of such six (6)-month
period (or such earlier date upon which such amount can be paid under Section 409A of the Code without resulting in a prohibited distribution, including as a result of your death), the Company shall pay you a lump-sum amount equal to the
cumulative amount that would have otherwise been payable to you during such six (6)-month period, plus interest thereon from the Termination Date through the payment date at a rate equal to the then-current “applicable Federal rate”
determined under Section 7872(f)(2)(A) of the Code. 

  
 5 

 (g) Release; Compliance with Covenants. Notwithstanding anything contained herein,
your right to receive the payments and benefits set forth in this Section 8 is conditioned on and subject to (i) your execution within twenty-one (21) days (or, to the extent required by applicable law, forty-five (45) days)
following the Termination Date and non-revocation within seven (7) days thereafter of a general release of claims against the Digital Group (as defined below), in a form reasonably acceptable to the Company, (ii) your continued compliance
with the restrictive covenants set forth in Section 10 of this Agreement and any similar covenants set forth in any other agreement between you and the Company, and (iii) your compliance with Section 8(e) above. 

(h) Definitions. For purposes of this Agreement: 

(A) “Cause” shall mean (1) your willful and continued failure to substantially perform your duties with
the Company (other than any such failure resulting from your incapacity due to physical or mental illness), after a written demand for substantial performance is delivered to you by the Company, which demand specifically identifies the manner in
which the Company believes that you have not substantially performed your duties and which failure is not cured within thirty (30) days of receiving such notice; (2) your willful commission of an act of fraud or dishonesty resulting in
economic or financial injury to the Company or its subsidiaries or affiliates; (3) your conviction of, or entry by you of a guilty or no contest plea to, the commission of a felony or a crime involving moral turpitude; (4) a willful breach
by you of any fiduciary duty owed to the Company which results in economic or other injury to the Company or its subsidiaries or affiliates; (5) your willful and gross misconduct in the performance of your duties hereunder that results in
economic or other injury to the Company or its subsidiaries or affiliates and which breach is not cured within thirty (30) days after written notification is delivered to you by the Company that specifically identifies the manner in which the
Company believes that you have breached any such duty; (6) your willful and material breach of your covenants set forth in Section 10 below; or (7) a material breach by you of any of your other obligations under this Agreement after
written notice is delivered to you by the Company which specifically identifies such breach. For purposes of this provision, no act or failure to act on your part will be considered “willful” unless it is done, or omitted to be done, by
you in bad faith or without reasonable belief that your action or omission was in the best interests of the Company. Notwithstanding the foregoing, in the event you incur a “separation from service” by reason of a termination of your
employment by the Company (other than by reason of your death or Disability or pursuant to clause (3) of this paragraph) on or within one year after a Change in Control or within the six month period immediately preceding a Change in Control in
connection with such Change in Control, it shall be presumed for purposes of this Agreement that such termination was effected by the Company other than for Cause unless the contrary is established by the Company. 

(B) “Disability” shall mean a disability that qualifies or, had you been a participant, would qualify you to
receive long-term disability payments under the Company’s group long-term disability insurance plan or program, as it may be amended from time to time. 

  
 6 

 (C) “Good Reason” shall mean the occurrence of any one or more
of the following events without your prior written consent, unless the Company fully corrects the circumstances constituting Good Reason (provided such circumstances are capable of correction) prior to the Termination Date: (1) the
Company’s assignment to you of any duties materially inconsistent with your position (including status, offices, titles and reporting requirements), authority, duties or responsibilities as contemplated by Section 2 hereof, or any other
action by the Company which results in a material diminution in such position, authority, duties or responsibilities, excluding for this purpose an isolated, insubstantial and inadvertent action not taken in bad faith and which is remedied by the
Company; (2) the Company’s material reduction of your annual base salary or bonus opportunity, each as in effect on the date hereof or as the same may be increased from time to time; (3) the relocation of the Company’s offices at
which you are principally employed (the “Principal Location”) to a location more than forty-five (45) miles from such location, or the Company’s requiring you to be based at a location more than forty-five (45) miles
from the Principal Location, except for required travel on Company business; (4) the Company requiring you to report to an officer other than the Chief Executive Officer of the Employer; or (5) a material breach by the Company of
Section 17 of this Agreement. Notwithstanding the foregoing, you will not be deemed to have resigned for Good Reason unless (x) you provide the Company with notice of the circumstances constituting Good Reason within sixty (60) days
after the initial occurrence or existence of such circumstances, (y) the Company fails to correct the circumstance so identified within thirty (30) days after the receipt of such notice (if capable of correction), and (z) the
Termination Date occurs no later than one hundred eighty (180) days after the initial occurrence of the event constituting Good Reason. 

(D) “Prior Year Bonus” shall mean, for any Termination Date that occurs between January 1 of any fiscal
year and the date that annual bonuses are paid by the Company for the immediately preceding year (the “Prior Year”), your target annual bonus (without giving effect to any reduction which constitutes Good Reason) for such Prior
Year, unless the Compensation Committee has determined your bonus for such Prior Year, in which case the Prior Year Bonus shall be the bonus determined by the Compensation Committee, if any. The Prior Year Bonus, if any, shall be in lieu of your
annual bonus for the Prior Year. There will be no Prior Year Bonus in connection with any Termination Date that occurs on or after the date the Company pays annual bonuses for the Prior Year through the end of the year in which the Termination Date
occurs. 
 (E) “Stub Year Bonus” shall mean the product obtained by multiplying (x) your target annual
bonus for the fiscal year in which the Termination Date occurs (without giving effect to any reduction which constitutes Good Reason) multiplied by (y) a fraction, the numerator of which is the number of calendar days that have elapsed in the
then current fiscal year through the Termination Date and the denominator of which is 365. 
 9. LIMITATION ON PAYMENTS. 

(a) Best Pay Cap. Notwithstanding any other provision of this Agreement, in 

  
 7 

 
the event that any payment or benefit received or to be received by you (including any payment or benefit received in connection with a termination of your employment, whether pursuant to the
terms of this Agreement or any other plan, arrangement or agreement) (all such payments and benefits, including the payments and benefits under Section 8 of this Agreement, the “Total Payments”) would be subject (in whole or
part) to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), then, after taking into account any reduction in the Total Payments provided by reason of Section 280G of the Code in such other plan,
arrangement or agreement, your remaining Total Payments shall be reduced to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax, but only if (i) the net amount of such Total Payments, as so reduced (and
after subtracting the net amount of federal, state and local income taxes applicable to such reduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such reduced Total
Payments) is greater than or equal to (ii) the net amount of such Total Payments without such reduction (but after subtracting the net amount of federal, state and local income taxes on such Total Payments and the amount of Excise Tax to which
you would be subject in respect of such unreduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such unreduced Total Payments). The reduction undertaken pursuant to this
Section 9(a) shall be accomplished first by reducing or eliminating any cash payments subject to Section 409A of the Code as deferred compensation (with payments to be made furthest in the future being reduced first), then by reducing or
eliminating cash payments that are not subject to Section 409A of the Code, then by reducing payments attributable to equity-based compensation (or the accelerated vesting thereof) subject to Section 409A of the Code as deferred
compensation (with payments to be made furthest in the future being reduced first), and finally by reducing payments attributable to equity-based compensation (or the accelerated vesting thereof) that is not subject to Section 409A of the Code.

 (b) Certain Exclusions. For purposes of determining whether and the extent to which the Total Payments will be subject to
the Excise Tax, (i) no portion of the Total Payments, the receipt or retention of which you have waived at such time and in such manner so as not to constitute a “payment” within the meaning of Section 280G(b) of the Code, will
be taken into account; (ii) no portion of the Total Payments will be taken into account which, in the written opinion of an independent, nationally recognized accounting firm (the “Independent Advisors”) selected by the
Company, does not constitute a “parachute payment” within the meaning of Section 280G(b)(2) of the Code (including by reason of Section 280G(b)(4)(A) of the Code) and, in calculating the Excise Tax, no portion of such Total
Payments will be taken into account which, in the opinion of Independent Advisors, constitutes reasonable compensation for services actually rendered, within the meaning of Section 280G(b)(4)(B) of the Code, in excess of the “base
amount” (as defined in Section 280G(b)(3) of the Code) allocable to such reasonable compensation; and (iii) the value of any non-cash benefit or any deferred payment or benefit included in the Total Payments shall be determined by the
Independent Advisors in accordance with the principles of Sections 280G(d)(3) and (4) of the Code. 
 10. RESTRICTIVE COVENANTS.

Company containing certain 

  
 8 

 
nondisclosure, intellectual property assignment, non- competition and non-solicitation provisions, in substantially the form attached hereto as Exhibit A (the “Proprietary

You further agree that, upon termination of your employment, you will not receive or remove from the files or offices of the Digital Group any originals or copies of documents or other materials (physical, electronic or otherwise) of the Digital

the projects in which any member of the Digital Group is involved or contemplating. You agree that, upon termination of your employment, you will maintain in strict confidence and not disclose the projects in which the Digital Group is involved or
contemplating. 
 (c) You further agree that during the Term, you shall not, unless agreed to in writing by the Company, engage in
Competition (as defined below). For purposes of this Agreement, “Competition” shall mean acquiring or owning interests in, directly or indirectly, including as a principal, partner, stockholder or manager of any partnership,

active management role. 
 (d) You further agree that during the Term and continuing through the first (1st) anniversary of the date of termination of your employment, you will not directly or indirectly solicit, induce, or encourage (i) any then-current employee of any member of the Digital
Group to terimnate their employment with such member of the Digital Group, or (ii) any

obligations under Sections 10(a), (b), (c) or (d) above, that monetary damages for such breach would not be readily calculable, and that the Company would not have an adequate remedy at law therefor, you acknowledge, consent and agree that
in the event of such breach, or the threat thereof, the Company shall be entitled, in addition to any other legal remedies and damages available, to specific performance thereof and to temporary and permanent injunctive relief (without the necessity

(a) To the extent applicable, this Agreement shall be interpreted and applied consistent and in accordance with Section 409A of the Code
and Department of Treasury regulations and other interpretive guidance issued thereunder. Notwithstanding any provision of this Agreement to the contrary, if at any time you and the Company mutually determine that any compensation or benefits
payable under this Agreement may not be compliant with or exempt from Section 409A of the Code and related Department of Treasury guidance, the parties shall work together to adopt such amendments to this Agreement or adopt other policies and
procedures (including amendments, policies and procedures with retroactive effect), or take such other actions, as the parties determine are necessary or appropriate to (i) exempt such compensation and benefits from Section 409A of the
Code and/or preserve the intended tax treatment of such compensation and benefits, or (ii) comply with the requirements of Section 409A of the Code and related Department of Treasury guidance; provided, however, that this
Section 11(a) shall not create any obligation on the part of the Company to adopt any such amendment, policy or procedure or take any such other action. 

(b) To the extent permitted under Section 409A of the Code, any separate payment or benefit under this Agreement or otherwise shall not
be deemed “nonqualified deferred compensation” subject to Section 409A of the Code and Section 8(f) hereof to the extent provided in the exceptions in Treasury Regulation Section 1.409A-1(b)(4), Section 1.409A-1(b)(9)
or any other applicable exception or provision of Section 409A of the Code. 
 (c) To the extent that compensation or benefits payable
under Section 8 of this Agreement (i) constitute “nonqualified deferred compensation” within the meaning of Section 409A of the Code or (ii) are intended to be exempt from Section 409A of the Code under Treasury
Regulation Section 1.409A-1(b)(9)(iii), and are designated under this Agreement as payable upon (or within a specified time following) your termination of employment, such compensation or benefits shall, subject to Section 8(f) hereof, be

 10 

 (d) To the extent that any payments or reimbursements provided to you under this Agreement are
deemed to constitute compensation to which Treasury Regulation Section 1.409A-3(i)(1)(iv) would apply, such amounts shall be paid or reimbursed to you reasonably promptly, but not later than December 31 of the year following the year in
which the expense was incurred. The amount of any such payments eligible for reimbursement in one year shall not affect the payments or expenses that are eligible for payment or reimbursement in any other taxable year, and your right to such
payments or reimbursement shall not be subject to liquidation or exchange for any other benefit. 
 12. COMPANY RULES AND
REGULATIONS. As an employee of the Company, you agree to abide by Company rules and regulations as set forth in the Company’s Employee Handbook, Code of Conduct and Business Ethics, Statement of Policies and Procedures Governing Material
Non-Public Information and the Prevention of Insider Trading and as otherwise promulgated. 
 13. PAYMENT OF FINANCIAL
OBLIGATIONS. In the event that your employment or consultancy is shared among the Company and/or its subsidiaries and affiliates, the payment or provision to you by the Company of any remuneration, benefits or other financial obligations

Agreement, are fully aware of its legal effect, and have entered into it freely based on your own judgment.

	 	Re:	EMPLOYMENT TERMS 

 Dear Mr. Appleby: 

Digital Realty Trust, Inc. (the “REIT”) and DLR LLC (the “Employer” and together with the REIT, the
“Company”) are pleased to offer you employment with the REIT and the Employer on the terms and conditions set forth in this letter (this “Agreement”), effective as of April 20, 2015 (the “Effective
Date”).  
 1. TERM. Subject to the provisions for earlier termination hereinafter provided, your employment
hereunder shall be for a term (the “Term”) commencing on the Effective Date and ending on the third (3rd) anniversary of the Effective Date (the “Initial Termination
Date”). If not previously terminated, the Term shall automatically be extended for one additional year on the Initial Termination Date, unless either you or the Company elect not to so extend the Term by notifying the other party, in
writing, of such election not less than sixty (60) days prior to the Initial Termination Date. 
 2. POSITION, DUTIES
AND RESPONSIBILITIES. During the Term, the Company will employ you, and you agree to be employed by the Company, as Chief Operating Officer of the REIT and the Employer. In the capacity of Chief Operating Officer, you will have such duties and
responsibilities as are normally associated with such position and will devote your full business time and attention to serving the Company in such position. Your duties may be changed from time to time by the Company, consistent with your position.
You will report to the Chief Executive Officer of the Company. You will initially work full-time at our offices in Ashburn, Virginia and, following your relocation to the San Francisco greater metropolitan area in accordance with Section 6 of
this Agreement, will work full-time at our principal offices located in San Francisco, California (or such other location in the San Francisco greater metropolitan area as the Company may utilize as its principal offices), except for travel to other
locations as may be necessary to fulfill your responsibilities. At the Company’s request, you will serve the Company and/or its subsidiaries and affiliates in other offices and capacities in addition to the foregoing. In the event that you
serve in any one or more of such additional capacities, your compensation will not be increased beyond that specified in this Agreement. In addition, in the event your service in one or more of such additional capacities is terminated, your
compensation, as specified in this Agreement, will not be diminished or reduced in any manner as a result of such termination for so long as you otherwise remain employed under the terms of this Agreement. 

 3. BASE COMPENSATION. During the Term, the Company will pay you a base salary of
$425,000 per year, less payroll deductions and all required withholdings, payable in accordance with the Company’s normal payroll practices and prorated for any partial month of employment. Your annual base salary may be increased, but not
decreased, by the Compensation Committee of the Board of Directors of the REIT (the “Compensation Committee”) in its discretion pursuant to the Company’s policies as in effect from time to time, and such increased amount
thereafter will be your base salary per year for purposes of this Agreement. 
 4. ANNUAL BONUS. In addition to the
base salary set forth above, during the Term, you will be eligible to participate in the Company’s incentive bonus plan applicable to similarly situated executives of the Company. The amount of your annual bonus will be based on the attainment
of performance criteria established and evaluated by the Company in accordance with the terms of such bonus plan as in effect from time to time, provided that, subject to the terms of such bonus plan and attainment of performance criteria
established by the Company, your target and maximum annual bonus shall be one hundred percent (100%) and one hundred fifty percent (150%), respectively, of your base salary for such year. Any annual bonus that becomes payable to you is intended
to satisfy the short-term deferral exemption under Treasury Regulation Section 1.409A-1(b)(4) and shall be made not later than the last day of the applicable two and one-half (2  1⁄2) month “short-term deferral period” with respect to such annual bonus, within the meaning of Treasury Regulation Section 1.409A-1(b)(4). 

5. BENEFITS AND VACATION. During the Term, you will be eligible to participate in all incentive, savings and retirement plans,
practices, policies and programs maintained or sponsored by the Company from time to time which are applicable to other similarly situated executives of the Company, subject to the terms and conditions thereof. During the Term, you will also be
eligible for standard benefits, such as medical insurance, paid time-off and holidays to the extent applicable generally to other similarly situated executives of the Company, subject to the terms and conditions of the applicable Company plans or
policies. 
 6. RELOCATION BENEFITS. You agree to relocate to San Francisco, California greater metropolitan area by
the end of the fourth (4th) calendar quarter of 2015. You will be entitled to receive reimbursement for the costs of all reasonable relocation expenses (not to exceed $250,000, net of any
applicable taxes) incurred in connection with your relocation to the San Francisco, California area in accordance with the expense reimbursement policies and practices of the Company that are applicable to other similarly situated executives of the
Company (the “Relocation Expenses”). In addition, for a period of up to four (4) weeks, you will be entitled to receive reimbursement for the reasonable costs of your lodging, temporary living and/or house hunting expenses in
the San Francisco, California area in accordance with the expense reimbursement policies and practices of the Company that are applicable to other similarly situated executives of the Company (the “Temporary Housing Expenses”). As
soon as administratively practicable following your relocation (but in no event more than thirty (30) days thereafter), subject to and conditioned upon your continued employment through the 

  
 2 

 
applicable payment date, the Company will pay you an amount in cash equal to $35,417, subject to applicable federal, state, and local tax withholding, and other authorized deductions (the
“Relocation Payment” and, together with the Relocation Expenses and Temporary Housing Expenses, the “Relocation Benefits”). Should you voluntarily resign within one year from the date of your final relocation to the
San Francisco, California area, you will be required to repay the Company the full amount of Relocation Benefits actually received by you.  

7. LONG-TERM INCENTIVE AWARDS. Subject to approval by the Compensation Committee, the REIT agrees to grant to you in your
capacity as an employee of the Company and in consideration of your provision of services to the Company, (i) an award of profits interest units of Digital Realty Trust, L.P. (the “Operating Partnership”) which will be subject
to time-based vesting equivalent to approximately $650,000 and (ii) an award of Class D profits interest units of the Operating Partnership which will be subject to performance-based vesting equivalent to approximately $1,350,000 (collectively,
the “Grants”). Alternatively, if you do not qualify as an accredited investor or if you otherwise so elect, you will receive (i) a restricted stock unit grant subject to time-based vesting in lieu of profits interest units
and (ii) a restricted stock unit grant subject to performance-based vesting in lieu of the Class D profits interest units. The number of profits interest units and Class D profits interest units (or, if applicable, restricted stock units)
to be issued will be determined on the date of Compensation Committee approval or such other day as the Compensation Committee may determine. Subject to your continued employment with the Company, the Grants shall vest in accordance with a vesting
schedule approved by the Compensation Committee. Consistent with the foregoing, the terms and conditions of the Grants shall be set forth in profits interest unit and Class D profits interest units agreements (or, if applicable, restricted
stock unit Agreements) which will be provided to you for acceptance and as evidence of such Grants as soon as administratively possible following the grant date. During your employment with the Company, you will be eligible to receive annual
equity awards subject to time-based and/or performance-based vesting conditions as determined by the Compensation Committee in its discretion.  

8. TERMINATION OF EMPLOYMENT. 

(a) Without Cause or for Good Reason. Subject to Section 8(g) below, in the event of a termination of your
employment during the Term by the Company without Cause or by you for Good Reason (each as defined below), then, in addition to any other accrued amounts payable to you through the date of termination of your employment (such date, or the date of
your death if applicable under Section 8(c) below, the “Termination Date”), the Company will pay and provide you with the following payments and benefits: 

(i) payable within thirty (30) days after your Termination Date (with the exact payment date to be determined by the Company in its
discretion), a lump-sum severance payment in an amount equal to the sum of (x) one (1.0) (the “Severance Multiple”) times the sum of (A) your annual base salary as in effect on the Termination Date, plus (B) your
target annual bonus for the fiscal year in which the Termination Date occurs (in the case of both (A) and (B), without giving effect to any reduction which constitutes Good Reason), (y) the Stub Year Bonus, plus (z) the Prior Year
Bonus, if any; 

  
 3 

 (ii) for a period commencing on the Termination Date and ending on the earlier of (x) the
twelve (12)-month anniversary of the Termination Date or (y) the date on which you become eligible to receive comparable group health insurance coverage under a subsequent employer’s plans, the Company shall continue to provide you and
your eligible family members with group health insurance coverage at least equal to that which would have been provided to you if your employment had not been terminated (including, in the discretion of the Company, by purchasing COBRA coverage for
you and your eligible family members); provided, however, that if (A) any plan pursuant to which the Company is providing such coverage is not, or ceases prior to the expiration of the period of continuation coverage to be, exempt
from the application of Section 409A of the Code (as defined below) under Treasury Regulation Section 1.409A-1(a)(5), or (B) the Company is otherwise unable to continue to cover you under its group health plans or doing so would
jeopardize the tax-qualified status of such plans, then, in either case, an amount equal to the monthly plan premium payment shall thereafter be paid to you as currently taxable compensation in substantially equal monthly installments over the
continuation period (or the remaining portion thereof); 
 (iii) for a period commencing on the Termination Date and ending on the twelve
(12)-month anniversary of the Termination Date, the Company shall, at its sole expense and on an as-incurred basis, provide you with outplacement counseling services directly related to your termination of employment with the Company, the provider
of which shall be selected by the Company; and 
 (iv) to the extent that any outstanding Company equity-based awards issued to you under
the Company’s equity incentive plans are subject to vesting based on continued employment or the lapse of time, such awards shall become vested and exercisable immediately prior to the Termination Date. The vesting of any awards that are
subject to vesting based on the satisfaction of performance goals, including, without limitation, any performance-based profits interest units of the Operating Partnership and other “outperformance awards” issued to you, shall be governed
by the terms of the award agreements evidencing such awards. For purposes of clarification, except as otherwise provided under any award agreements relating to such awards, the terms set forth in this Agreement, including this Section 8, are
intended to be in addition to (and not in lieu of) the vesting and acceleration features related to such stock options and other equity-based awards (including profits interest units of the Operating Partnership and other “outperformance
awards”) held by you and included elsewhere, including in any award agreements related to such awards, and the vesting and acceleration terms hereof shall be applicable only to the extent they result in additional acceleration or vesting of
such stock options and other equity-based awards held by you. 
 (b) Change in Control. Subject to Section 8(g) below, in
the event that a Change in Control (as defined in the Digital Realty Trust, Inc., Digital Services, Inc. and Digital Realty Trust, L.P. 2014 Incentive Award Plan or any successor incentive plan) occurs during the Term and, on the date of or within
one year after such Change in Control, you incur a termination of employment by the Company without Cause or by you for Good Reason (each as defined below), then, in addition to any other accrued amounts payable to you through the Termination Date,
you shall be entitled to the payments and benefits provided in Section 8(a) hereof, subject to the terms and conditions thereof, except that, for purposes of this Section 8(b), the Severance Multiple shall be equal to two (2.0). 

  
 4 

 (c) Death or Disability. Subject to Section 8(g) below, and notwithstanding
anything to the contrary contained herein, in the event of a termination of your employment during the Term by reason of your death or Disability (as defined below), then, in addition to any other accrued amounts payable to you through the
Termination Date, the Company will pay and provide you (or your estate or legal representative) with the following payments and benefits: 

(i) payable within thirty (30) days after your Termination Date (with the exact payment date to be determined by the Company in its
discretion), a lump-sum severance payment in an amount equal to the sum of (w) your annual base salary as in effect on the Termination Date, (x) your target annual bonus for the fiscal year in which the Termination Date occurs,
(y) the Stub Year Bonus, plus (z) the Prior Year Bonus, if any; and 
 (ii) to the extent that any outstanding Company
equity-based awards issued to you under the Company’s equity incentive plans are subject to vesting based on continued employment or the lapse of time, such awards shall become vested and exercisable immediately prior to the Termination Date.
The vesting of any awards that are subject to vesting based on the satisfaction of performance goals, including, without limitation, any performance-based profits interest units of the Operating Partnership and other “outperformance
awards” issued to you, shall be governed by the terms of the award agreements evidencing such awards. 
 (d) Expiration;
Non-renewal. Notwithstanding anything contained herein, in no event shall the expiration of the Term set forth in Section 1 above or the Company’s election not to renew or extend the Term or your employment with the Company
constitute a termination your employment by the Company without Cause. 
 (e) Termination of Offices and Directorships. Upon a
termination of your employment for any reason, except to the extent otherwise determined by the Board of Directors of the REIT (the “Board”) in its sole discretion, you shall be deemed to have resigned from all offices,
directorships and other employment positions, if any, then held with the Company or any member of the Digital Group (as defined below), and you agree that you shall take all actions reasonably requested by the Company to effectuate the foregoing.

 (f) Potential Six-Month Delay. Notwithstanding anything to the contrary in this Agreement, no compensation or benefits,
including without limitation any termination payments or benefits payable under this Section 8, shall be paid to you prior to the expiration of the six (6)-month period following your “separation from service” from the Company (within
the meaning of Section 409A(a)(2)(A)(i) of the Internal Revenue Code of 1986, as amended (the “Code”)) to the extent that the Company determines that paying such amounts at the time or times indicated in this Agreement would be
a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code. If the payment of any such amounts is delayed as a result of the previous sentence, then on the first business day following the end of such six (6)-month period (or such
earlier date upon which such amount can be paid under Section 409A of the Code 

  
 5 

 
without resulting in a prohibited distribution, including as a result of your death), the Company shall pay you a lump-sum amount equal to the cumulative amount that would have otherwise been
payable to you during such six (6)-month period, plus interest thereon from the Termination Date through the payment date at a rate equal to the then-current “applicable Federal rate” determined under Section 7872(f)(2)(A) of the
Code. 
 (g) Release; Compliance with Covenants. Notwithstanding anything contained herein, your right to receive the payments
and benefits set forth in this Section 8 is conditioned on and subject to (i) your execution within twenty-one (21) days (or, to the extent required by applicable law, forty-five (45) days) following the Termination Date and
non-revocation within seven (7) days thereafter of a general release of claims against the Digital Group (as defined below), in a form reasonably acceptable to the Company, (ii) your continued compliance with the restrictive covenants set
forth in Section 10 of this Agreement and any similar covenants set forth in any other agreement between you and the Company, and (iii) your compliance with Section 8(e) above. 

(h) Definitions. For purposes of this Agreement: 

(A) “Cause” shall mean (1) your willful and continued failure to substantially perform your duties with
the Company (other than any such failure resulting from your incapacity due to physical or mental illness), after a written demand for substantial performance is delivered to you by the Company, which demand specifically identifies the manner in
which the Company believes that you have not substantially performed your duties and which failure is not cured within thirty (30) days of receiving such notice; (2) your willful commission of an act of fraud or dishonesty resulting in
economic or financial injury to the Company or its subsidiaries or affiliates; (3) your conviction of, or entry by you of a guilty or no contest plea to, the commission of a felony or a crime involving moral turpitude; (4) a willful breach
by you of any fiduciary duty owed to the Company which results in economic or other injury to the Company or its subsidiaries or affiliates; (5) your willful and gross misconduct in the performance of your duties hereunder that results in
economic or other injury to the Company or its subsidiaries or affiliates and which breach is not cured within thirty (30) days after written notification is delivered to you by the Company that specifically identifies the manner in which the
Company believes that you have breached any such duty; (6) your willful and material breach of your covenants set forth in Section 10 below; or (7) a material breach by you of any of your other obligations under this Agreement after
written notice is delivered to you by the Company which specifically identifies such breach. For purposes of this provision, no act or failure to act on your part will be considered “willful” unless it is done, or omitted to be done, by
you in bad faith or without reasonable belief that your action or omission was in the best interests of the Company. Notwithstanding the foregoing, in the event you incur a “separation from service” by reason of a termination of your
employment by the Company (other than by reason of your death or Disability or pursuant to clause (3) of this paragraph) on or within one year after a Change in Control or within the six month period immediately preceding a Change in Control in
connection with such Change in Control, it shall be presumed for purposes of this Agreement that such termination was effected by the Company other than for Cause unless the contrary is established by the Company. 

  
 6 

 (B) “Disability” shall mean a disability that qualifies or, had
you been a participant, would qualify you to receive long-term disability payments under the Company’s group long-term disability insurance plan or program, as it may be amended from time to time. 

(C) “Good Reason” shall mean the occurrence of any one or more of the following events without your prior
written consent, unless the Company fully corrects the circumstances constituting Good Reason (provided such circumstances are capable of correction) prior to the Termination Date: (1) the Company’s assignment to you of any duties
materially inconsistent with your position (including status, offices, titles and reporting requirements), authority, duties or responsibilities as contemplated by Section 2 hereof, or any other action by the Company which results in a material
diminution in such position, authority, duties or responsibilities, excluding for this purpose an isolated, insubstantial and inadvertent action not taken in bad faith and which is remedied by the Company; (2) the Company’s material
reduction of your annual base salary or bonus opportunity, each as in effect on the date hereof or as the same may be increased from time to time; (3) the relocation of the Company’s offices at which you are principally employed (the
“Principal Location”) to a location more than forty-five (45) miles from such location, or the Company’s requiring you to be based at a location more than forty-five (45) miles from the Principal Location, except as
otherwise provided in Section 6 above or for required travel on Company business; or (4) a material breach by the Company of Section 17 of this Agreement. Notwithstanding the foregoing, you will not be deemed to have resigned for Good
Reason unless (x) you provide the Company with notice of the circumstances constituting Good Reason within sixty (60) days after the initial occurrence or existence of such circumstances, (y) the Company fails to correct the
circumstance so identified within thirty (30) days after the receipt of such notice (if capable of correction), and (z) the Termination Date occurs no later than one hundred eighty (180) days after the initial occurrence of the event
constituting Good Reason. 
 (D) “Prior Year Bonus” shall mean, for any Termination Date that occurs between
January 1 of any fiscal year and the date that annual bonuses are paid by the Company for the immediately preceding year (the “Prior Year”), your target annual bonus (without giving effect to any reduction which constitutes
Good Reason) for such Prior Year, unless the Compensation Committee has determined your bonus for such Prior Year, in which case the Prior Year Bonus shall be the bonus determined by the Compensation Committee, if any. The Prior Year Bonus, if any,
shall be in lieu of your annual bonus for the Prior Year. There will be no Prior Year Bonus in connection with any Termination Date that occurs on or after the date the Company pays annual bonuses for the Prior Year through the end of the year in
which the Termination Date occurs. 
 (E) “Stub Year Bonus” shall mean the product obtained by multiplying
(x) your target annual bonus for the fiscal year in which the Termination 

  
 7 

 
Date occurs (without giving effect to any reduction which constitutes Good Reason) multiplied by (y) a fraction, the numerator of which is the number of calendar days that have elapsed in
the then current fiscal year through the Termination Date and the denominator of which is 365. 
 9. LIMITATION ON PAYMENTS. 

(a) Best Pay Cap. Notwithstanding any other provision of this Agreement, in the event that any payment or benefit received or to
be received by you (including any payment or benefit received in connection with a termination of your employment, whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement) (all such payments and benefits,
including the payments and benefits under Section 8 of this Agreement, the “Total Payments”) would be subject (in whole or part) to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”),
then, after taking into account any reduction in the Total Payments provided by reason of Section 280G of the Code in such other plan, arrangement or agreement, your remaining Total Payments shall be reduced to the extent necessary so that no
portion of the Total Payments is subject to the Excise Tax, but only if (i) the net amount of such Total Payments, as so reduced (and after subtracting the net amount of federal, state and local income taxes applicable to such reduced Total
Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such reduced Total Payments) is greater than or equal to (ii) the net amount of such Total Payments without such reduction (but
after subtracting the net amount of federal, state and local income taxes on such Total Payments and the amount of Excise Tax to which you would be subject in respect of such unreduced Total Payments and after taking into account the phase out of
itemized deductions and personal exemptions attributable to such unreduced Total Payments). The reduction undertaken pursuant to this Section 9(a) shall be accomplished first by reducing or eliminating any cash payments subject to
Section 409A of the Code as deferred compensation (with payments to be made furthest in the future being reduced first), then by reducing or eliminating cash payments that are not subject to Section 409A of the Code, then by reducing
payments attributable to equity-based compensation (or the accelerated vesting thereof) subject to Section 409A of the Code as deferred compensation (with payments to be made furthest in the future being reduced first), and finally by reducing
payments attributable to equity-based compensation (or the accelerated vesting thereof) that is not subject to Section 409A of the Code. 

(b) Certain Exclusions. For purposes of determining whether and the extent to which the Total Payments will be subject to the
Excise Tax, (i) no portion of the Total Payments, the receipt or retention of which you have waived at such time and in such manner so as not to constitute a “payment” within the meaning of Section 280G(b) of the Code, will be
taken into account; (ii) no portion of the Total Payments will be taken into account which, in the written opinion of an independent, nationally recognized accounting firm (the “Independent Advisors”) selected by the Company,
does not constitute a “parachute payment” within the meaning of Section 280G(b)(2) of the Code (including by reason of Section 280G(b)(4)(A) of the Code) and, in calculating the Excise Tax, no portion of such Total Payments will
be taken into account which, in the opinion of Independent Advisors, constitutes reasonable compensation for services actually rendered, within the meaning of Section 280G(b)(4)(B) of the Code, in

  
 8 

 
excess of the “base amount” (as defined in Section 280G(b)(3) of the Code) allocable to such reasonable compensation; and (iii) the value of any non-cash benefit or any
deferred payment or benefit included in the Total Payments shall be determined by the Independent Advisors in accordance with the principles of Sections 280G(d)(3) and (4) of the Code. 

10. RESTRICTIVE COVENANTS. 

(a) You acknowledge and agree that, concurrently with the execution of this Agreement, you are entering into an agreement with the Company
containing certain nondisclosure, intellectual property assignment, non- competition and non-solicitation provisions, in substantially the form attached hereto as Exhibit A (the “Proprietary Information Agreement”), and that
you shall be bound by, and shall comply with your obligations under, the Proprietary Information Agreement. Notwithstanding the foregoing, in the event of any inconsistency between the Proprietary Information Agreement and this Agreement, this
Agreement shall control. 
 (b) As a condition of your employment with the Company, you agree that during the Term and thereafter, you will
not directly or indirectly disclose or appropriate to your own use, or the use of any third party, any trade secret or confidential information concerning the REIT, the Operating Partnership, the Employer or their respective subsidiaries or
affiliates (collectively, the “Digital Group”) or their businesses, whether or not developed by you, except as it is required in connection with your services rendered for the Company. You further agree that, upon termination of
your employment, you will not receive or remove from the files or offices of the Digital Group any originals or copies of documents or other materials (physical, electronic or otherwise) of the Digital Group, and that you will return any such
documents or materials (physical, electronic or otherwise) otherwise in your possession. You further agree that, upon termination of your employment, you will maintain in strict confidence and not disclose the projects in which any member of the
Digital Group is involved or contemplating. You agree that, upon termination of your employment, you will maintain in strict confidence and not disclose the projects in which the Digital Group is involved or contemplating. 

(c) You further agree that during the Term, you shall not, unless agreed to in writing by the Company, engage in Competition (as defined
below). For purposes of this Agreement, “Competition” shall mean acquiring or owning interests in, directly or indirectly, including as a principal, partner, stockholder or manager of any partnership, corporation or any other
entity, Technology Real Estate located in the United States, Europe or Asia. “Technology Real Estate” shall mean commercial real estate buildings that are used principally (i) to provide infrastructure required by companies in

(9.5%) beneficial interest 

  
 9 

 
and have no active management role; provided, however, that in the case of investments involving Technology Real Estate described in clause (iv) above, investments in which you own more than
nine and one-half percent (9.5%) shall be permitted so long as (A) your aggregate capital invested in the investment is less than $500,000, (B) you own less than a fifty percent (50%) beneficial interest, and (C) you have no
active management role. 
 (d) You further agree that during the Term and continuing through the first (1st) anniversary of the date of termination of your employment, you will not directly or indirectly solicit, induce, or encourage (i) any then-current employee of any member of the Digital
Group to terimnate their employment with such member of the Digital Group, or (ii) any consultant, agent, customer, vendor, or other parties doing business with any member of the Digital Group to terminate their agency, or other relationship
with such member of the Digital Group or to transfer their business from the such member or the Digital Group and you will not initiate discussion with any such person for any such purpose or authorize or knowingly cooperate with the taking of any
such actions by any other individual or entity. 
 (e) In recognition of the facts that irreparable injury will result to the Company in the
event of a breach by you of your obligations under Sections 10(a), (b), (c) or (d) above, that monetary damages for such breach would not be readily calculable, and that the Company would not have an adequate remedy at law therefor, you
acknowledge, consent and agree that in the event of such breach, or the threat thereof, the Company shall be entitled, in addition to any other legal remedies and damages available, to specific performance thereof and to temporary and permanent
injunctive relief (without the necessity of posting a bond) to restrain the violation or threatened violation of such obligations by you. 

11. CODE SECTION 409A. 

(a) To the extent applicable, this Agreement shall be interpreted and applied consistent and in accordance with Section 409A of the Code
and Department of Treasury regulations and other interpretive guidance issued thereunder. Notwithstanding any provision of this Agreement to the contrary, if at any time you and the Company mutually determine that any compensation or benefits
payable under this Agreement may not be compliant with or exempt from Section 409A of the Code and related Department of Treasury guidance, the parties shall work together to adopt such amendments to this Agreement or adopt other policies and
procedures (including amendments, policies and procedures with retroactive effect), or take such other actions, as the parties determine are necessary or appropriate to (i) exempt such compensation and benefits from Section 409A of the
Code and/or preserve the intended tax treatment of such compensation and benefits, or (ii) comply with the requirements of Section 409A of the Code and related Department of Treasury guidance; provided, however, that this
Section 11(a) shall not create any obligation on the part of the Company to adopt any such amendment, policy or procedure or take any such other action. 

(b) To the extent permitted under Section 409A of the Code, any separate payment or benefit under this Agreement or otherwise shall not
be deemed “nonqualified deferred compensation” subject to Section 409A of the Code and Section 8(f) hereof to the extent provided in the exceptions in Treasury Regulation Section 1.409A-1(b)(4), Section 1.409A-1(b)(9)
or any other applicable exception or provision of Section 409A of the Code. 

  
 10 

 (c) To the extent that compensation or benefits payable under Section 8 of this Agreement
(i) constitute “nonqualified deferred compensation” within the meaning of Section 409A of the Code or (ii) are intended to be exempt from Section 409A of the Code under Treasury Regulation
Section 1.409A-1(b)(9)(iii), and are designated under this Agreement as payable upon (or within a specified time following) your termination of employment, such compensation or benefits shall, subject to Section 8(f) hereof, be payable
only upon (or, as applicable, within the specified time following) your “separation from service” from the Company (within the meaning of Section 409A(a)(2)(A)(i) of the Code). 

(d) To the extent that any payments or reimbursements provided to you under this Agreement are deemed to constitute compensation to which
Treasury Regulation Section 1.409A-3(i)(1)(iv) would apply, such amounts shall be paid or reimbursed to you reasonably promptly, but not later than December 31 of the year following the year in which the expense was incurred. The amount of
any such payments eligible for reimbursement in one year shall not affect the payments or expenses that are eligible for payment or reimbursement in any other taxable year, and your right to such payments or reimbursement shall not be subject to
liquidation or exchange for any other benefit. 
 12. COMPANY RULES AND REGULATIONS. As an employee of the Company, you agree
to abide by Company rules and regulations as set forth in the Company’s Employee Handbook, Code of Conduct and Business Ethics, Statement of Policies and Procedures Governing Material Non-Public Information and the Prevention of Insider Trading
and as otherwise promulgated. 
 13. PAYMENT OF FINANCIAL OBLIGATIONS. In the event that your employment or consultancy
is shared among the Company and/or its subsidiaries and affiliates, the payment or provision to you by the Company of any remuneration, benefits or other financial obligations pursuant to this Agreement may be allocated to the Company and, as
applicable, its subsidiaries and/or affiliates in accordance with an employee sharing or expense allocation agreement entered into by such parties. 

14. WITHHOLDING. The Company may withhold from any amounts payable under this Agreement such Federal, state, local or foreign
taxes as shall be required to be withheld pursuant to any applicable law or regulation. 
 15. ARBITRATION. Except as
set forth in Section 10(d) above, any disagreement, dispute, controversy or claim arising out of or relating to this Agreement or the interpretation of this Agreement or any arrangements relating to this Agreement or contemplated in this
Agreement or the breach, termination or invalidity thereof shall be settled by final and binding arbitration before a single neutral arbitrator. Arbitration shall be administered by JAMS in San Francisco, California in accordance with the then
existing JAMS Arbitration Rules and Procedures for Employment Disputes. Except as provided herein, the Federal Arbitration Act  

  
 11 

 
shall govern the interpretation, enforcement and all proceedings. The arbitrator shall apply the substantive law (and the law of remedies, if applicable) of the state of California, or federal
law, or both, as applicable, and the arbitrator is without jurisdiction to apply any different substantive law. The arbitrator shall have the authority to entertain a motion to dismiss and/or a motion for summary judgment by any party and shall
apply the standards governing such motions under the Federal Rules of Civil Procedure. Judgment upon the award may be entered in any court having jurisdiction thereof. Each party shall pay his or its own attorneys’ fees and costs of suit
associated with such arbitration to the extent permitted by applicable law, and the Company shall pay the administrative fees and all arbitrator fees associated with such arbitration; provided, however, that if you prevail in such arbitration, the
Company shall reimburse you for the reasonable attorneys’ fees actually incurred by you in connection with such arbitration. 

16. ENTIRE AGREEMENT. As of the Effective Date, this Agreement, together with the Proprietary Information Agreement, constitutes
the final, complete and exclusive agreement between you and the Company with respect to the subject matter hereof and replaces and supersedes any and all other agreements, offers or promises, whether oral or written, made to you by any member of the
Digital Group or any entity, or representative thereof, whose business or assets any member of the Digital Group succeeded to in connection with the initial public offering of the REIT’s common stock or the transactions related thereto. This
Agreement may not be amended or modified otherwise than by a written agreement executed by the parties hereto or their respective successors and legal representatives. 

17. ASSUMPTION BY SUCCESSOR. The Company shall require any successor (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such
succession had taken place. 
 18. ACKNOWLEDGEMENT. You hereby acknowledge (a) that you have consulted with or
have had the opportunity to consult with independent counsel of your own choice concerning this Agreement, and have been advised to do so by the Company, and (b) that you have read and understand this Agreement, are fully aware of its legal
effect, and have entered into it freely based on your own judgment. 
 19. GOVERNING LAW. This Agreement shall be
governed by and construed in accordance with the laws of the State of California, without regard to conflicts of laws principles thereof.
