THIS SEPARATION AND CONSULTING AGREEMENT (this “Agreement”), dated as of March 13, 2015, is made by and between Digital Realty Trust, Inc. (the “REIT”), DLR LLC (the “Employer” and together with the REIT, the “Company”), and David Caron (“Caron”).

WHEREAS, Caron and the Company previously entered into that certain letter agreement, dated as of July 30, 2004 and amended on December 4, 2008 (as amended, the “Employment Letter”), pursuant to which Caron is employed as Senior Vice President, Portfolio Management of the Company;

WHEREAS, effective as of March 13, 2015, Caron has resigned from his position as Senior Vice President, Portfolio Management of the Company, and as an employee of the Company, and Caron and the Company desire to specify the terms of Caron’s termination of employment and to provide for the termination of the Employment Letter; and

WHEREAS, in connection with Caron’s resignation, the Company wishes to secure the services of Caron as a consultant to the Company upon the terms and subject to the conditions set forth herein, and Caron wishes to render such services to the Company upon the terms and subject to the conditions set forth herein.

NOW, THEREFORE, in consideration of the mutual agreements set forth herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1. Resignation.

a. Resignation; Termination of Employment Letter. Effective as of March 13, 2015 (the “Termination Date”), Caron hereby resigns as an employee and officer of the Company and its subsidiaries and affiliates. Caron and the Company acknowledge and agree that, except as expressly provided in Section 3.b below, the termination of Caron’s employment shall not constitute a termination by the Company without Cause for purposes of the Employment Letter or any other agreement between Caron and the Company or its subsidiaries or affiliates. In addition, effective as of the Termination Date, the Employment Letter shall terminate, and Caron shall have no further right or interest thereunder, except as provided in this Agreement, provided, however, that notwithstanding the foregoing, Section 9 (Confidentiality and Non-Solicitation) of the Employment Letter shall remain in full force and effect in accordance with its terms.

b. Accrued Obligations. On the Termination Date, the Company will pay to Caron all accrued salary and all accrued and unused paid time off earned through the Termination Date, subject to standard payroll deductions and withholdings.

1

c. Expenses. Caron acknowledges that, within fifteen days (15) days after the Termination Date, Caron will submit his final documented expense reimbursement statement reflecting all business expenses incurred by him through the Termination Date, if any, for which he seeks reimbursement. The Company will reimburse Caron for any such expenses pursuant to its regular business practices.

d. Return of Company Property. On or before the Termination Date, Caron shall return to the Company all Company documents (and all copies thereof) and other Company property in his possession or control, including, but not limited to: Company files, correspondence, memoranda, notes, notebooks, books, records, plans, forecasts, reports, proposals, agreements, financial information, personnel information, marketing information, research and development information, information regarding business contacts, customers, vendors, strategies, products, computer-recorded information, databases, computer programs, tangible property and equipment, credit cards, entry cards, keys and computer access codes; and any materials of any kind that contain or embody any proprietary or confidential information of the Company (and all reproductions thereof in whole or in part). Caron represents that he has made a diligent search to locate any such documents, property and information. In addition, if Caron has used any non-Company computer, server, or e-mail system to receive, store, review, prepare or transmit any Company confidential or proprietary data, materials or information, he shall immediately provide the Company with a computer-useable copy of such information and then permanently delete and expunge such Company confidential or proprietary information from those systems. Caron agrees to provide the Company with access to such systems as requested to verify that the necessary copying and/or deletion has been completed. Caron’s compliance with the terms of this Section 1.d and Section 7 below is a condition to his right to receive and retain the payments and benefits set forth in Sections 3.a and 3.b below.

2. Consulting Services. During the period commencing on the Termination Date and ending on the twelve (12)-month anniversary of the Termination Date or such earlier date on which Caron’s consulting relationship with the Company is terminated as provided herein (the “Consulting Period”), Caron shall provide the consulting services specified on Exhibit A hereto and such other services as reasonably requested by the Company (the “Consulting Services”). Caron shall provide the Consulting Services to the Company at times and locations mutually agreed to by Caron and the Company. Caron shall comply with all applicable policies and procedures of the Company (including, without limitation, technology use, confidentiality, background check and work authorization policies and procedures).

3. Compensation, Equity Awards; Expense Reimbursements.

a. Fees. In consideration of, and subject to and conditioned upon Caron’s execution and non-revocation of the Releases set forth in Section 4 below, and Caron’s continued compliance with the terms and conditions of this Agreement, including without limitation, the confidentiality, non-solicitation, non-competition and non-disparagement covenants contained in Section 7 below, the Company shall compensate Caron as follows for the Consulting Services:

2

(1) During the Consulting Period, the Company shall pay Caron a consulting fee (the “Consulting Fee”) equal to $29,329 per month.

(2) In addition to the Consulting Fee, the Company shall pay to Caron an additional amount equal to $261,712 (the “Additional Fee”). Payment of the Additional Fee will be made in a single lump sum on (i) the twelve (12) month anniversary of the Termination Date, provided that Caron continues to provide the Consulting Services until such date and has not breached any of his obligations under this Agreement, or (ii) if earlier, the date on which the Company terminates Caron’s consulting relationship hereunder without Cause.

(3) During the period commencing on the Termination Date and ending on the earlier of (i) the last day of the Consulting Period, and (ii) the date on which Caron becomes eligible for coverage under a subsequent employer’s group health plan (in any case, the “COBRA Period”), subject to Caron’s valid election to continue healthcare coverage under Section 4980B of the Code and the regulations thereunder, the Company shall continue to provide to Caron and Caron’s dependents coverage under its group health plan at the same levels as in effect on the Termination Date and at the same proportional cost to Caron as if Caron remained an employee of the Company throughout the Consulting Period; provided, however, that if (A) any plan pursuant to which such benefits are provided is not, or ceases prior to the expiration of the continuation coverage period to be, exempt from the application of Section 409A (as defined below) under Treasury Regulation Section 1.409A-1(a)(5), (B) the Company is otherwise unable to continue to cover Caron or Caron’s dependents under its group health plans, or (C) the Company cannot provide the benefit without violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then, in any such case, an amount equal to each remaining Company subsidy shall thereafter be paid to Caron in substantially equal monthly installments over the COBRA Period (or remaining portion thereof) (the benefits or payment under this Section 3.a(3), the “COBRA Benefit”).

b. Equity Awards. Caron represents and acknowledges that except as set forth on Exhibit B attached hereto, he has no outstanding equity awards or equity-based awards with respect to the REIT, Digital Realty Trust, L.P. (the “Operating Partnership”) or any affiliate thereof (the “Equity Awards”), or any other rights to acquire stock or equity interests of any such entity. Each outstanding Equity Award held by Caron will be treated in accordance with the terms of the applicable plan document and award agreement governing such Equity Award. The Company acknowledges that, as of the date hereof, a portion of the Equity Awards have vested. In addition, notwithstanding the foregoing sentence, the outstanding Equity Awards held by Caron shall be treated as follows:

3

(1) Pre-2014 Equity Awards. Each outstanding Equity Award held by Caron that has a Date of Grant (as set forth on Exhibit B) that occurred prior to January 1, 2014 shall vest in full (to the extent then-unvested) upon (i) the twelve (12)-month anniversary of the Termination Date (such date, the “Twelve-Month Vesting Date”), provided that Caron continues to provide the Consulting Services until such date and Caron has not breached his obligations under this Agreement, or (ii) if earlier, the date on which the Company terminates Caron’s consulting relationship hereunder without Cause (as defined in Section 5 below).

(2) Class D Profits Interest Units. In addition, solely for purposes of that certain Class D Profits Interest Unit Agreement, dated as of February 11, 2014, by and between the REIT, the Operating Partnership, and Caron (the “Class D Agreement”), Caron shall be deemed to incur a Qualifying Termination by the Company without Cause (each as defined in the Class D Agreement) upon the Twelve-Month Vesting Date if either (i) Caron continues to provide the Consulting Services until such date and Caron has not breached his obligations under this Agreement, or (ii) the Company terminates Caron’s consulting relationship hereunder without Cause prior to the Twelve-Month Vesting Date.

(3) 2014 Time-Based Profits Interest Units. If the Company terminates Caron’s consulting relationship hereunder without Cause prior to the Twelve-Month Vesting Date, then the award of unvested profits interest units granted to Caron pursuant to that certain Time-Based Profits Interest Unit Agreement, dated as of February 11, 2014, by and between the REIT, the Operating Partnership, and Caron shall, as of the date of termination of the consulting relationship, vest with respect to that number of Profits Interest Units (as defined therein), if any, that would have vested during the period commencing on the date on which Caron’s consulting relationship terminates and ending on (and including) the Twelve-Month Vesting Date had Caron continued to provide the Consulting Services during such period.

(4) The parties acknowledge that, during the Consulting Period, Caron shall be deemed a “Service Provider” under the terms of the applicable plan document and award agreement governing each Equity Award held by Caron, subject to the conditions and qualifications set forth therein.

c. Expenses. The Company shall, in accordance with applicable Company policy, pay or reimburse Caron for reasonable and necessary business expenses actually incurred or paid by Caron during the Consulting Period in connection with the Consulting Services, subject to proper substantiation of such expenses in accordance with applicable Company policy. Without limiting the generality of the foregoing, all expenses in excess of $500 individually or $1,000 in the aggregate must be approved by the Company in writing in advance of being incurred, and all travel must be approved in writing in advance of such travel.

4. Release of Claims. Caron acknowledges and agrees that his right to receive and retain the payments and benefits set forth in Section 3.a and Section 3.b are subject to and conditioned upon his execution, delivery and non-revocation of a first general release of claims (a “First Release”) and a second general release of claims (a “Second Release”), respectively, in forms prescribed by the Company (collectively, the “Releases”). Caron shall execute and deliver the First Release on or within twenty-one (21) days following the Termination Date, and shall execute and deliver the Second Release on or within twenty-one (21) days following the date on which Caron’s consulting relationship terminates.

5. Termination. This Agreement and the consulting relationship established hereby may be terminated by either party with or without Cause at any time and for any reason upon the delivery of at least ten (10) days’ written notice to the other party; provided, however, that the Company may terminate this Agreement and the consulting relationship established hereby for Cause at any time and without notice. For purposes of this letter, “Cause” will be determined in the reasonable discretion of the Company, and will include, without limitation, the following: (i) material failure by Caron to exercise a reasonable level of skill and efficiency in performing the Consulting Services described in Exhibit A; (ii) misconduct by Caron which injures the general reputation of the Company or its subsidiaries or affiliates or interferes with contracts or operations of the Company or its subsidiaries or affiliates; (iii) Caron’s conviction of, or entry of a guilty or no contest plea to, a felony or any crime involving moral turpitude; (iv) fraud, misrepresentation, or breach of trust by Caron in the course of his services which adversely affects the Company or its subsidiaries or affiliates; (v) Caron’s willful and gross misconduct in the performance of the Consulting Services that results in economic or other injury to the Company or its subsidiaries or affiliates; (vi) a breach of the covenants set forth in Section 7 below; or (vii) a breach by Caron of any of his obligations under this Agreement.

6. Obligations of the Company Upon Termination. Upon the termination of the consulting relationship established hereby for any reason, all compensation payable to Caron under this Agreement shall cease as of the applicable date of such termination, and the Company shall pay to Caron, following such termination, a lump sum equal to any Consulting Fee earned or accrued and unpaid through the earlier of (i) the date of termination and (ii) if the Company terminated this Agreement for Cause, the date of the earliest event or occurrence giving rise to such Cause. In addition, in the event of the termination of the consulting relationship established hereby by the Company without Cause, subject to and conditioned upon Caron’s execution and non-revocation of the Second Release, the Company shall (i) pay to Caron the Consulting Fee that would have been payable for the remainder of the Consulting Period had the consulting relationship not terminated, payable in a single lump sum within thirty (30) days following the date of termination, and (ii) continue to provide Caron with the COBRA Benefit that would have been provided had the consulting relationship not terminated.
