Upon the termination of the Term for any reason, Executive agrees to return any and all property of the HTA Group and delete any confidential, proprietary or trade secret information of the HTA Group from any of Executive’s personal devices (other than any such information that is related to Executive’s continued service to the HTA Group as a member of the Board).

7.    Benefits.

(a)    While Executive remains in HTA’s employ as Interim CEO, Executive shall be eligible to participate in all of the various employee benefit plans and programs which are made available to similarly situated HTA officers, in accordance with the eligibility provisions and other terms and conditions of such plans and programs.

8.    Dispute Resolution. In the event that any dispute or disagreement arises between the Parties in connection with any provision of this Agreement, the Parties shall first submit such disagreements to mediation, which mediation shall occur in the county in the state in which Executive’s primary resident office is situated. Either Party may commence mediation by providing to Judicial Arbitration and Mediation Services, Inc. (“JAMS”) and the other party hereto a written request for mediation, setting forth the subject of the dispute and the relief requested.

The Parties hereto shall share equally in the costs of mediation. All offers, promises, conduct and statements, whether oral or written, made in the course of the mediation by any of the parties, their agents, employees, experts and attorneys, and by the mediator or any JAMS employees, are confidential, privileged and inadmissible for any purpose, including impeachment, in any proceeding involving the Parties, provided that evidence that is otherwise admissible or discoverable shall not be rendered inadmissible or non-discoverable as a result of its use in the mediation. Either Party may commence a legal action with respect to the matters submitted to mediation at any time following the initial mediation session or forty-five (45) days after the date of filing the written request for mediation, whichever occurs first.

9.    Termination.

(a)    Termination for Terminating Disability.

(i)    The Company may terminate the Executive’s employment if the Executive shall have been unable to perform, in the opinion of a competent physician selected by the Board (provided that Executive shall also be able to select a physician and an independent review in the event there is a dispute), any or all of the Executive’s material duties hereunder, either with or without reasonable accommodation, by reason of illness, physical or mental disability or other similar incapacity, which inability shall continue for more than three consecutive months, or any six months in a twelve-month period (a “Terminating Disability”).

(iv)    If the Company elects not to terminate the Term upon an event of a Terminating Disability and Executive returns to active employment with HTA prior to such a termination, or if such disability exists for less than the period of time necessary to constitute a Terminating Disability, the provisions of this Agreement shall remain in full force and effect.

(b)    Termination on Account of Death of Executive. The Term terminates immediately and automatically on the death of Executive; provided, however, that HTA shall pay Executive’s estate (1) the Accrued Obligations and (2) the Pro-Rata Bonus.

Upon termination for Cause, HTA shall pay Executive only the Accrued Obligations, and the Bonus and LTI Award shall be forfeited. Upon a termination for Cause, Executive shall immediately deliver to the Board his resignation as a member of the Board.

(d)    Termination of Term, Termination by Company Other than for Cause, Death, or Disability. HTA may terminate the Term immediately upon written notice to Executive for any reason.

(iii)    subject to clause (iv) below with respect to expiration of the Term on a Corporate Transaction, the Company shall pay in a lump sum within sixty days after such employment termination the difference between (A) one million two hundred thirty-seven thousand dollars ($1,237,000) multiplied by the Adjustment Factor (as defined below), and (B) the amount of any Bonus (but not including the Signing Bonus) paid to (or applied on behalf of) the Executive for services on and after the Effective Date under this Agreement, if any, subject to the obligation to provide transition services as described below; and

(iv)    if the Term expires on account of a Corporate Transaction, then in lieu of the amount under clause (iii) above, the Company shall pay in a lump sum within sixty days after such employment termination the difference between (A) one million eight hundred

(e)    Resignation by Executive. Executive may resign only upon ninety (90) days prior written notice to Board.

(f)    Section 9 Payments and Release. Upon termination of the Term as a result of an event of termination described in this Section 9 and except for the Company’s payment of the Accrued Obligations and other amounts described in this Section 9, all further compensation under this Agreement shall terminate. Executive further agrees that as a condition precedent to Executive’s receipt of payments and benefits under this Section 9 (other than the Accrued Obligations), upon HTA’s request and by a reasonable deadline set by the Company (to ensure that payments can be made by the dates specified in this Section 9 following the expiration of the time for revocation of the Release (as defined below) as permitted by law), Executive shall (i) execute a release agreement that sets forth (A) the date of Executive’s termination and the effect of his termination under the compensation and benefit plans of the HTA Group, (B) the compensation and benefits to be received under this Agreement and any conditions to their receipt provided for in this Agreement, (C) covenants requiring Executive to maintain the confidentiality of the HTA Group’s confidential information and to return any property of the HTA Group and (D) a release of claims in the substantially the form attached as Exhibit B hereto (subject to updates to the extent necessary to reflect changes in applicable law) (the “Release”), and (ii) execute and not revoke the Release.

(g)    Additional Terms. To the extent provided below, the following provisions apply under this Section 9 and the other provisions of the Agreement.

(i)    “Accrued Obligations” shall mean (A) any Base Salary accrued through the date of termination, (B) the portion of the Bonus, if any, earned but not yet paid for the year preceding the year in which the termination occurs, subject to certification by the Compensation Committee of any performance goals applicable to such Bonus, (C) reimbursement for any business expenses properly incurred prior to the date of termination and (D) any nonforfeitable amounts or benefits, including continuation and conversion rights, provided under any employee benefit plan, not including any severance, separation pay or supplemental unemployment benefit plan, in accordance with the terms of such plan.

(ii)    Executive shall not be required to seek or accept other employment, or otherwise to mitigate damages, as a condition to the receipt of any payments or benefits under this Section 9, and the payments and benefits under this Section 9 shall not be offset by any compensation or other amounts received from any other source.

(iii)    This Agreement and the amounts payable and other benefits hereunder are intended to comply with, or otherwise be exempt from, Section 409A of the Code (“Section 409A”). This Agreement shall be administered, interpreted and construed in a manner consistent with Section 409A. If any provision of this Agreement is found not to comply with, or otherwise not to be exempt from, the provisions of Section 409A, it shall be modified and given effect, in the sole discretion of the Board or Compensation Committee and without requiring Executive’s consent, in such manner as the Board or Compensation Committee determines to be necessary or appropriate to comply with, or to effectuate an exemption from, Section 409A. Each payment under this Agreement shall be treated as a separate identified payment for purposes of Section 409A, include the short-term deferral and the severance pay exemptions provided under Treasury regulations. The preceding provisions shall not be construed as a guarantee by HTA of any particular tax effect to Executive of the payments and other benefits under this Agreement.

(A)    With respect to any reimbursement of expenses of, or any provision of in-kind benefits to, Executive, as specified under this Agreement, such reimbursement of expenses or provision of in-kind benefits shall be subject to the following conditions: (1) the expenses eligible for reimbursement or the amount of in-kind benefits provided in one taxable year shall not affect the expenses eligible for reimbursement or the amount of in-kind benefits provided in any other taxable year, except for any medical reimbursement arrangement providing for the reimbursement of expenses referred to in Section 105(b) of the Code; (2) the reimbursement of an eligible expense shall be made no later than the end of the year after the year in which such expense was incurred; and (3) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit.

(B)    If a payment obligation under this Agreement arises on account of Executive’s termination of employment and if such payment is deferred compensation (as defined under Treasury Regulation Section 1.409A-1(b)(1)) subject to Section 409A, the payment shall be paid only in connection with Executive’s separation from service (as defined in

Treas. Reg. Section 1.409A-1(h)). If a payment obligation under this Agreement arises on account of Executive’s separation from service (as defined under Treas. Reg. Section 1.409A-1(h)) while Executive is a specified employee (as defined under Treas. Reg. Section 1.409A-1(h) and using the identification methodology selected by the Company from time to time), any payment of deferred compensation (as defined under Treasury Regulation Section 1.409A-1(b)(1), after giving effect to the exemptions in Treasury Regulation Sections 1.409A-1(b)(3) through (b)(12)) that is scheduled to be paid within six months after such separation from service shall accrue without interest and shall be paid on the first day of the seventh month beginning after the date of Executive’s separation from service or, if earlier, within fifteen (15) days following Executive’s death.

10.    Withholdings. All amounts payable under this Agreement will be subject to withholdings as required by law. Executive shall be personally subject to pay all taxes with respect to compensation and benefits provided as required under this Agreement regardless of how much HTA withholds for applicable taxes.

11.    Assignment. All rights and duties of Executive arising under this Agreement, and the Agreement itself, are non-assignable by Executive. HTA may elect to assign this Agreement, provided that such assignment, other than to a successor to the Company’s business that expressly adopts and agrees to be bound by this Agreement, shall not relieve HTA of its obligations under this Agreement, and HTA shall guarantee payment and performance of all such obligations by the assignee.

12.    Notices. Any notice required or permitted to be given under this Agreement shall be sufficient if in writing and if delivered personally or by certified mail to Executive at Executive’s place of residence as then recorded on the HTA’s books or to the Company at its principal office.

13.    Waiver. No waiver or modification of this Agreement or the terms contained herein shall be valid unless in writing and duly executed by the party to be charged therewith. The waiver by any Party hereto of a breach of any provision of this Agreement by the other Party shall not operate or be construed as a waiver of any subsequent breach by such party.

14.    Governing Law; Venue. This Agreement, the rights and obligations of the parties hereto, and any claims or disputes relating thereto, shall be governed by and construed in accordance with the laws of the state in which Executive’s primary resident office is situated (but not including the choice of law rules thereof). The parties hereto further agree that the sole and exclusive forum for litigating any disputes arising under the terms of this Agreement shall be a court of competent jurisdiction in the state in which Executive’s primary resident office is situated (but not including the choice of law rules thereof) for all disputes not covered by Section 8.

15.    Entire Agreement. This Agreement, together with the award agreement with respect to the LTI Award and the Equity Plan, contains the entire agreement of the parties with respect to Executive’s employment by the Company, and supersedes any and all prior agreements between or among the parties. There are no other contracts, agreements, or understandings, whether oral or written, existing between them except as contained or referred to in this Agreement or evidencing equity awards granted in respect of Board service. With respect to the LTI Award and any other equity awards granted to Executive in connection with his employment, (a) in the event of any conflict between the terms of this Agreement, on the one hand, and the terms of the Equity Plan and any award agreement (including the award agreement with respect to the LTI Award), on the other hand, the terms of the applicable award agreement shall govern, and (b) in the event of any conflict between the terms of this Agreement and the terms of the Equity Plan, the terms of this Agreement shall govern (other than any purported conflict relating to terms of the Equity Plan that would require shareholder approval to amend, in which case, the terms of the Equity Plan shall govern).

16.    Severability. In case one or more of the provisions of this Agreement is held to be invalid, illegal, or unenforceable in any respect, such invalidity, illegality or other enforceability shall not affect any other provisions hereof, and this Agreement shall be construed as if such invalid, illegal or unenforceable provisions have never been contained herein.

17.    Successors and Assigns. Subject to the requirements of Section 11 above, this Agreement shall be binding upon Executive, the Company and the Company’s successors and assigns.

(a)    Anything in this Agreement to the contrary notwithstanding, in the event it shall be determined that any payment or distribution by the Company to or for the benefit of Executive (whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise) (a “Payment”) would be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then, prior to the making of any Payment to the Executive a calculation shall be made comparing (i) the net benefit to Executive of the Payment after payment of the Excise Tax, to (ii) the net benefit to the Executive if the Payment had been limited to the extent necessary to avoid being subject to the Excise Tax. If the amount calculated under (i) above is less than the amount calculated under (ii) above, then the Payment shall be limited to the extent necessary to avoid being subject to the Excise Tax (the “Reduced Amount”). The reduction of the Payments due hereunder, if applicable, shall be made by first reducing cash Payments and then, to the extent necessary, reducing those Payments having the next highest ratio of Parachute Value to actual present value of such Payments as of the date of the change of control, as determined by the Determination Firm (as defined in Section 18(b) below). For purposes of this Section 18, present value shall be determined in accordance with Section 280G(d)(4) of the Code. For purposes of this Section 18, the “Parachute Value” of a Payment means the present value as of the date of the change of control of the portion of such

Payment that constitutes a “parachute payment” under Section 280G(b)(2) of the Code, as determined by the Determination Firm for purposes of determining whether and to what extent the Excise Tax shall apply to such Payment.

(b)    The determination of whether an Excise Tax would be imposed, the amount of such Excise Tax, and the calculation of the amounts referred to Section 18(a)(i) and (ii) above shall be made by an independent, nationally recognized accounting firm or compensation consulting firm mutually acceptable to the Company and the Executive (the “Determination Firm”) which shall provide detailed supporting calculations. Any determination by the Determination Firm shall be binding upon the Company and Executive. As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial determination by the Determination Firm hereunder, it is possible that Payments which Executive was entitled to, but did not receive pursuant to Section 18(a), could have been made without the imposition of the Excise Tax (“Underpayment”). In such event, the Determination Firm shall determine the amount of the Underpayment that has occurred and any such Underpayment shall be promptly paid by the Company to or for the benefit of the Executive but no later than March 15 of the year after the year in which the Underpayment is determined to exist, which is when the legally binding right to such Underpayment arises.

(c)    In the event that the provisions of Code Section 280G and 4999 or any successor provisions are repealed without succession, this Section 18 shall be of no further force or effect.

(a)    Notwithstanding any other provision of this Agreement, nothing contained in this Agreement limits Executive’s ability to file a charge or complaint with the Equal Employment Opportunity Commission, the National Labor Relations Board, the Occupational Safety and Health Administration, the SEC or any other federal, state or local governmental agency or commission (collectively, “Government Agencies”), or from providing truthful testimony in response to a lawfully issued subpoena or court order. Executive understands that this Agreement does not limit his 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 HTA. In addition, Executive shall not be prohibited from providing any confidential information to the SEC, cooperating with or assisting in an SEC investigation or proceeding or receiving any monetary award as set forth in Section 21F of the Securities Exchange Act of 1934 or otherwise for information provided to the SEC.

(b)    The federal Defend Trade Secrets Act of 2016 (the “Act”) provides immunity from liability in certain circumstances for limited disclosures of trade secrets, as defined by the Act. Specifically, the trade secrets may be discloses: (i) 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 (ii) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Additionally, filing of a lawsuit for retaliation by an employer for reporting a suspected violation of law may use and disclose related trade secrets in the following manner: (A) the individual may disclose the trade secret to his/her attorney, and (B) 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.

20.    Counterparts. This Agreement may be executed in several counterparts, each of which shall be deemed an original, but all of which shall constitute one and the same instrument. Signatures delivered by facsimile or electronic means (including by pdf) shall be deemed effective for all purposes.
