In addition, if Peterson 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. Peterson agrees to provide the Company with a written certification verifying that the necessary copying and/or deletion has been completed.

2.Consulting Services. During the period commencing on the Termination Date and ending on February 28, 2019 or such earlier date on which Peterson’s consulting relationship with the Company is terminated as provided herein (the “Consulting Period”), Peterson shall provide such consulting services as may be mutually agreed by and between the Company and Peterson, including the Transitional Services (as set forth herein) as may be reasonably requested by the Company (the “Consulting Services”).

Peterson’s compliance with the terms of Sections 1.d, 7 and 8 of this Agreement (including any agreements or covenants cross-referenced therein) and execution and non-revocation of the Releases in accordance with Section 4 below are conditions to his right to receive and retain the Bonus and the continued vesting of his Equity Awards as set forth in Section 3.b.

and deliver the First Release within twenty-one (21) days following the Termination Date, and shall execute and deliver the Second Release within twenty-one (21) days following the date on which Peterson’s consulting relationship terminates.

Further, the parties agree that this Agreement does not limit Peterson’s ability to communicate with any Government Agencies or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, without notice to the Company. This Agreement does not limit Peterson’s right to receive an award for information provided to any Government Agencies.

5.Termination. The consulting relationship established hereby may not be terminated by either party prior to February 28, 2019, except that the Company may terminate the consulting relationship for Cause at any time or the consulting relationship may be terminated at any time by mutual agreement of the Company and Peterson.

6.Obligations of the Company Upon Termination. Upon the termination of the consulting relationship established hereby for any reason, the continued vesting of Peterson’s Equity Awards under this Agreement shall cease as of the applicable date of such termination. In addition, if the consulting relationship established hereby terminates due to the expiration of the Consulting Period or is earlier terminated by mutual agreement of the Company and Peterson, subject to and conditioned upon Peterson’s execution and non-revocation of the Second Release, the Company shall pay to Peterson, in accordance with the timing requirements specified in Section 3.a above, a lump sum payment equal to the Bonus, to the extent earned but unpaid prior to the date of termination. Except as expressly provided in this Section 6, Peterson shall not be entitled to any further payments in connection with or following the termination of the consulting relationship established hereby.

a.Confidentiality. Peterson agrees that during the Consulting Period and thereafter, he will not, directly or indirectly, disclose or appropriate to his own use, or the use of any third party, any trade secret or confidential information concerning the REIT, the Operating

Partnership, or their respective subsidiaries or affiliates (collectively, the “Digital Group”) or their businesses, whether or not developed by Peterson, except as required in connection with Peterson’s performance of the Consulting Services. Peterson further agrees that, upon termination of the consulting relationship hereunder, he 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) maintained in the ordinary course of business of the Digital Group, and that he will return any such documents or materials (physical, electronic, or otherwise) otherwise in his possession. Peterson further agrees that, upon termination of the consulting relationship, he will maintain in strict confidence the projects, including, but not limited to, leasing, build-to-suit, merger and acquisition transactions (including acquisitions of land), in which any member of the Digital Group is involved or contemplating (collectively, the “Digital Group Projects”).

The federal Defend Trade Secrets Act of 2016 (the “Act”) provides immunity from liability in certain circumstances to employees, contractors, and consultants for limited disclosures of Digital Group “trade secrets,” as defined by the Act. Specifically, employees, contractors, and consultants may disclose trade secrets: (1) in confidence, either directly or indirectly, to a federal, state, or local government official, or to an attorney, “solely for the purpose of reporting or investigating a suspected violation of law,” or (2) “in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal.” Additionally, employees, contractors, and consultants who file lawsuits for retaliation by an employer for reporting a suspected violation of law may use and disclose related trade secrets in the following manner: (1) the individual may disclose the trade secret to his/her attorney, and (2) the individual may use the information in the court proceeding, as long as the individual files any document containing the trade secret under seal and does not otherwise disclose the trade secret “except pursuant to court order.”

b.Non-Solicitation of Customers and Suppliers. Peterson agrees that during the Consulting Period, he will not, directly or indirectly, solicit, induce, or encourage any customer, vendor, or other party doing business with any member of the Digital Group to terminate or limit their existing contractual relationships with the Digital Group or such member or transfer their business from the Digital Group or such member, including in the context of any rights of first offer, renewals or extension options of any customer of the Digital Group, and he 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.

c.Non-Competition. Peterson covenants and agrees that during the Consulting Period, he shall comply with the Non-Competition Covenants set forth herein.

d.Non-Disparagement. Peterson agrees that during the Consulting Period and thereafter, he will not make any statement, publicly or privately, which disparages or would reasonably be expected to disparage the Digital Group or any of its employees, officers or directors. The Company agrees to instruct its executive officers and directors not to make, during the Consulting Period and thereafter, any statement, publicly or privately, which disparages or would reasonably be expected to disparage Peterson.

e.Proprietary Information and Inventions Assignment Agreement. Peterson acknowledges and agrees that he has executed that certain Proprietary Information and Inventions Assignment Agreement with the Employer, dated November 10, 2015, a copy of which is attached hereto as Exhibit B (the “PIIAA”), and that such agreement shall remain in full force and effect in accordance with its terms.

f.Interpretation. In the event the terms of this Section 7 shall be determined by any court of competent jurisdiction to be unenforceable by reason of its extending for too great a period of time or over too great a geographical area or by reason of its being too extensive in any other respect, it will be interpreted to extend only over the maximum period of time for which it may be enforceable, over the maximum geographical area as to which it may be enforceable, or to the maximum extent in all other respects as to which it may be enforceable, all as determined by such court in such action.

8.Cooperation. During the Consulting Period and thereafter, Peterson shall cooperate with the Digital Group, upon the reasonable request of the Company, with respect to any internal investigation or administrative, regulatory, or judicial proceeding involving matters that arose during Peterson’s employment with the Company (including, without limitation, Peterson being available to the Digital Group upon reasonable notice for interviews and factual investigations, appearing at the reasonable request of the Company to give testimony without requiring service of a subpoena or other legal process, and turning over to the Digital Group all relevant Digital Group documents which are or may have come into Peterson’s possession during his employment); provided, however, that any such request by the Company shall not be unduly burdensome or unreasonably interfere with Peterson’s personal schedule or ability to engage in gainful employment and the Company shall reimburse Peterson for any actual, reasonable, out-of-pocket expenses incurred in connection with providing any such cooperation.

Nothing herein is intended to be or will be construed to prevent, impede, or interfere with Peterson’s right to respond accurately and fully to any question, inquiry, or request for information regarding the Digital Group or his or her employment with the Company when required by legal process, or from initiating communications directly with, or responding to any inquiry from, or providing truthful testimony and information to, any federal, state, or other regulatory authority in the course of an investigation or proceeding authorized by law and carried out by such agency. Peterson is not required to contact the Digital Group regarding the subject matter of any such communications before they engage in such communications.

9.References. Any and all inquiries made by outside third parties concerning the employment of Peterson by the Company shall be directed to Cindy Fiedelman, Chief Human Resources Officer. The Company agrees that if contacted by a prospective employer of Peterson, it will only verify dates of employment, salary as of the Termination Date and job classification held by Peterson.

10.Independent Contractor. The Company and Peterson expressly agree that, during the Consulting Period, Peterson is solely an independent contractor and neither Peterson nor any principal, employee, or contractor of Peterson shall be construed to be an employee of the Company

in any matter under any circumstances or for any purposes whatsoever. Nothing in this Agreement shall establish an agency, partnership, joint venture, or employee relationship between the Company and Peterson, and Peterson shall not represent himself as an employee or officer of the Company. The Company and Peterson agree and acknowledge that neither party hereto renders legal, tax, or accounting advice to the other party.

Without limiting any other right of indemnification, contribution or recovery, if the Company or its officers, directors, employees, or agents incur any liability or expense as a result of any claim that any of the above representations and warranties are not true or have been breached or that arise from Peterson’s negligent performance of the Consulting Services, Peterson shall indemnify the Company, its officers, directors, employees, and agents and hold each of them harmless against all such liability or expense, including reasonable attorney’s fees.
