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 $ 260,000 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 base salary

 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

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. COMPENSATION GROSS-UP. The amount of compensation payable to you pursuant to
Sections 3 and 4 above will be “grossed up” as necessary (on an after-tax basis) to compensate for any duplicate social security withholding taxes due as a result of your shared employment by the Employer, the REIT and, if applicable, any
subsidiary and/or affiliate thereof; provided however, that no such gross-up will be made to the extent you will be entitled to a refund of any such amounts. Any such gross-up payments shall be made by December 31 of the year following
the year in which the duplicate taxes were incurred. The amount of any such payments in one year shall not affect the amount eligible for payment in any subsequent year and your right to payment of any such amounts shall not be subject to
liquidation or exchange for any other benefit. 
 7. TERMINATION OF
EMPLOYMENT. 
 (a) Without Cause or for Good Reason. Subject to paragraph
(e) 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, subject to Section 7(d) below, in 

  

 2 

 
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 7(c) below, the “Termination Date”), the Company will pay you within 60 days after your Termination Date, a lump-sum severance payment in an amount equal to the following: 
 (i) your annual base salary as in effect on the Termination Date; plus 
 (ii) the Stub Year Bonus; plus 
 (iii) the Prior Year Bonus, if any. 
 (b) Change in Control. Subject to
paragraph (e) below, in the event that a Change in Control (as defined in the First Amended and Restated Digital Realty Trust, Inc., Digital Services, Inc. and Digital Realty Trust, L.P. 2004 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, subject to
Section 7(d) below, in lieu of the severance payment set forth in Section 7(a) above, the Company will pay and provide you with the following payments and benefits in addition to any other accrued amounts payable to you through the
Termination Date: 
 (i) payable within 60 days after your Termination Date, a lump-sum severance payment in an amount equal
to: the sum of (w) two times your annual base salary as in effect on the Termination Date plus (x) two times the greater of (i) your target annual bonus for the fiscal year in which the Termination Date occurs or (ii) the annual
bonus paid or payable to you by the Company for the fiscal year immediately preceding the fiscal year in which the Termination Date occurs (in the case of both (w) and (x), without giving effect to any reduction which constitutes Good Reason),
plus (y) the Stub Year Bonus, plus (z) the Prior Year Bonus, if any; 
 (ii) for a period ending on the earlier of
(A) the first anniversary of the Termination Date or (B) 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); 
 (iii) to the extent that any outstanding Company stock options or other equity-based
awards issued to you under the Company’s equity incentive plans (other than any Class C profits interest units of Digital Realty Trust, L.P. (the “Operating Partnership”)) 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, Class
C profits interest units of the Operating Partnership and other “outperformance awards” issued to you, 

  

 3 

 
shall be governed by the terms of the award agreements evidencing such awards. For purposes of clarification, the terms set forth in this Agreement,
including this Section 7, 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 Class C 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. 
 (c) Death or
Disability. Subject to paragraph (e) 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,
subject to Section 7(d) below, 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 60 days after your Termination Date, 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 plus (x) your maximum annual bonus for the fiscal year in which the Termination Date occurs, plus (y) the Stub Year Bonus, plus (z) the Prior Year Bonus, if any;
and 
 (ii) to the extent that any outstanding Company stock options or other equity-based awards issued to you under the
Company’s equity incentive plans (other than any Class C profits interest units of the Operating Partnership) 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; 
 (iii) to the extent that any outstanding Company stock options or other equity-based awards
issued to you under the Company’s equity incentive plans are subject to vesting based on the satisfaction of performance goals, such awards shall remain outstanding and eligible to vest following the Termination Date in accordance with the
terms of the applicable award agreement. Without limiting the generality of the foregoing, you shall continue to be deemed to be a Service Provider under, and you shall not be deemed to have incurred a termination of service for purposes of, that
certain Class C Profits Interest Units Agreement, dated October 27, 2005 (the “2005 Class C Agreement”), that certain Class C Profits Interest Units Agreement, dated May 2, 2007 (the “2007 Class C
Agreement”) and any future award agreement evidencing future grants of Class C profits interests (together with the 2005 Class C Agreement and the 2007 Class C Agreement, the “Class C Agreements”) until all Class C profits
interest units issued pursuant to the applicable Class C Agreement that ultimately satisfy the Performance Condition (as defined in the applicable Class C Agreement), if any, vest. For purposes of clarification, this Section 7(c)(iii) shall be
applicable whether your termination occurs prior to or following the Measurement Date (as defined in the applicable Class C Agreement). In addition, if this Section 7(c)(iii) is applicable and any 

  

 4 

 
Restricted Stock is otherwise to be issued under Section 4.1 of the 2005 Class C Agreement or Section [4.1] of the 2007 Class C Agreement (or any
analogous section of any future Class C Agreement), fully-vested, unrestricted Common Stock of the Company shall be granted in lieu of any such Restricted Stock. 
 (d) 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 7, shall be paid to you during the 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 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 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. 
 (e) Release. Your right to receive the payments and benefits set forth in this Section 7 is
conditioned on and subject to the execution within 45 days following the Termination Date and non-revocation by you (or your estate or legal representative) of a general release of claims against the Digital Group (as defined below), in a form
reasonably acceptable to the Company. 
 (f) 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; (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; (6) your willful
and material breach of your covenants set forth in Section 9 below; or (7) a material breach by you of any of your 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. 
  

 5 

 (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, in each case, 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 45 miles from such location, or the Company’s requiring you to be based at a location more than 45 miles from the Principal Location, except for required travel on Company business;
or (4) a material breach by the Company of Section 16 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 60 days after the initial occurrence or existence of such circumstances, (y) the Company fails to correct the circumstance so identified within 30 days after the receipt of such notice (if capable of correction),
and (z) the Termination Date occurs no later than 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 maximum 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 maximum 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.

 8. EXCISE TAX GROSS-UP
PAYMENT. 
 (a) Except as set forth below, in the event it shall be determined that any
payment or distribution to you or for your benefit which is in the nature of compensation and is contingent on a change in the ownership or effective control of the REIT or the ownership of a substantial portion of the assets of the REIT (within the
meaning of Section 280G(b)(2) of the Code), whether paid or payable pursuant to this Agreement or otherwise (a “Payment”), would be subject (in whole or in part) to the excise tax imposed by Section 4999 of the Code
(together with any interest or penalties imposed with respect to such excise tax, the “Excise Tax”), then you shall be entitled to receive an additional payment (the “Excise Tax Gross-Up Payment”) in an amount such
that, after payment by you of all taxes (and any interest or penalties imposed with respect to such taxes), including, without limitation, any income taxes and Excise Tax imposed upon the Excise Tax Gross-Up Payment, you retain an amount of the
Excise Tax Gross-Up Payment equal to the Excise Tax imposed upon the Payments. Notwithstanding anything contained herein, if it shall be determined that you are entitled to the Excise Tax Gross-Up Payment, but that the Parachute Value (as defined
below) of all Payments does not exceed 110% of an amount equal to 2.99 times your “base amount,” within the meaning of Section 280G(b)(3) of the Code (the “Safe Harbor Amount”), then no Excise Tax Gross-Up Payment
shall be made to you and the amounts payable under this Agreement shall be reduced so that the Parachute Value of all Payments, in the aggregate, equals the Safe Harbor Amount. The reduction of the amounts payable hereunder, if applicable, shall be
made in such a manner as to maximize the economic present value as of the date of the change in control transaction of all Payments actually made to you. For purposes of this Agreement, the “Parachute Value” of a Payment shall mean
the present value as of the date of the change in control transaction for purposes of Section 280G of the Code of the portion of such Payment that constitutes a “parachute payment” under Section 280G(b)(2) of the Code. The
Company’s obligation to make Excise Tax Gross-Up Payments under this Section 8 shall not be conditioned upon your termination of employment or your “separation from service” (within the meaning of Section 409A(a)(2)(A)(i) of
the Code). For purposes of determining the amount of any Excise Tax Gross-Up Payment, you shall be considered to pay federal income tax at your actual marginal rate of federal income taxation in the calendar year in which the Excise Tax Gross-Up
Payment is to be made and state and local income taxes at your actual marginal rate of taxation in the state and locality of your residence on the date on which the Excise Tax Gross-Up Payment is calculated for purposes of this Section 8, net
of your actual reduction in federal income taxes which could be obtained from deduction of such state and local taxes, and taking into consideration the phase-out of your itemized deductions under federal income tax law. 
 (b) All determinations required to be made under this Section 8, including whether and when an Excise Tax Gross-Up Payment is
required, the amount of such Excise Tax Gross-Up Payment and the assumptions to be utilized in arriving at such determination, shall be made by such nationally recognized accounting firm as may be selected by the Board of Directors of the REIT as
constituted immediately prior to the change in control transaction (the “Accounting Firm”), provided, that the Accounting Firm’s determination shall be made based 

  

 7 

 
upon “substantial authority” within the meaning of Section 6662 of the Code. The Accounting Firm shall provide its determination (the
“Determination”), together with detailed supporting calculations and documentation, to you and the Company within 15 business days following the date of termination if applicable, or such other time as requested by you (provided
that you reasonably believe that any of the Payments may be subject to the Excise Tax) or the Company. All fees and expenses of the Accounting Firm shall be borne solely by the Company. Any Excise Tax Gross-Up Payment, as determined pursuant to this
Section 8, shall be paid by the Company to you no later than the later of (i) 15 business days following the receipt of the Accounting Firm’s Determination or (ii) 15 business days preceding the date the Excise Tax becomes
payable; provided, however, that in no event shall any such Excise Tax Gross-Up Payment or any payment of any income or other taxes to be paid by the Company under this Section 8 be made later than the end of your taxable year next
following your taxable year in which you remit the related taxes. Any costs and expenses incurred by the Company on behalf of you under this Section 8 due to any tax contest, audit or litigation will be paid by the Company by the end of your
taxable year following your taxable year in which the taxes that are the subject of the tax contest, audit or litigation are remitted to the taxing authority, or where as a result of such tax contest, audit or litigation no taxes are remitted, the
end of your taxable year following your taxable year in which the audit is completed or there is a final and non-appealable settlement or other resolution of the contest or litigation. 
 (c) You shall immediately notify the Company in writing of any claim by the Internal Revenue Service that, if successful, would require
the payment by the Company of the Excise Tax Gross-Up Payment. You shall not pay such claim prior to the expiration of the 30-day period following the date on which you give such notice to the Company (or such shorter period ending on the date that
any payment of taxes with respect to such claim is due). If the Company notifies you in writing prior to the expiration of such period that the Company desires to contest such claim, you shall give the Company all information reasonably requested by
the Company relating to such claim, cooperate with the Company and take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to time, and permit the Company to participate in and control
any proceedings relating to such claim; provided, however, that the Company shall bear and pay directly all costs and expenses incurred in connection with such contest, and shall indemnify and hold you harmless, on an after-tax basis, for any
Excise Tax or income tax (including interest and penalties) imposed as a result of such representation and contest. 
 9.
RESTRICTIVE COVENANTS. 
 (a) 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 

  

 8 

 
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. 
 (b)
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 or Europe. “Technology Real Estate” shall
mean commercial real estate buildings that are used principally (i) to provide infrastructure required by companies in the data, voice and wireless communications industry; (ii) to provide the physical environment required for businesses
in the disaster recovery, IT outsourcing and collocation industries, (iii) to provide highly specialized manufacturing environments for manufacturing of technology products or (iv) as headquarter office facilities for technology companies
(or any combination of the foregoing). Notwithstanding the foregoing, “Competition” shall not include (x) your activities as an employee, executive, director, principal, partner, stockholder or manager of the Company or any of its
subsidiaries or affiliates, or (y) investments in which you own less than a 9.5% beneficial interest 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 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 50% beneficial interest, and
(C) you have no active management role. 
 (c) You further agree that during the Term and continuing through the first
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 terminate 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. 

(d) 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 9(a), (b) or (c) 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. 
  

 9 

 10. CODE SECTION 409A. 
 (a) The payments described in subparagraphs 7(a) and 7(b)(i) above are intended to
satisfy the short-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 payments, within the meaning of Treasury Regulation Section 1.409A-1(b)(4). 
 (b) Certain payments and benefits under this Agreement are intended to be exempt from the application of Section 409A of the Code,
while other payments hereunder may constitute “nonqualified deferred compensation” within the meaning of Section 409A of the Code, the payment of which is intended to comply with Section 409A of the Code. To the extent
applicable, this Agreement shall be interpreted 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 the regulations promulgated thereunder.

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. 
 12.
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. 
 13. 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. 
 14. ARBITRATION. Except as set forth in Section 9(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 administered by JAMS/Endispute in San Francisco, California in accordance with the then existing JAMS/Endispute Arbitration Rules and Procedures for Employment Disputes. Except as provided herein, the Federal Arbitration Act
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 

  

 10 

 
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 expenses associated with such arbitration to the extent permitted by
applicable law; provided, however, that if you prevail in such arbitration, the Company shall reimburse you for the fees and expenses actually incurred by you in connection with such arbitration (including, without limitation, your reasonable
attorneys’ fees). 
 15. ENTIRE AGREEMENT. As of the Effective Date, this 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. You agree that any such agreement, offer or promise is hereby terminated and will be of no further force or effect, and that upon his execution of this Agreement, you will have no right or interest in or with respect to any such agreement,
offer or promise. 
 16. 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. 
 17.
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.
