CHANGE IN CONTROL AGREEMENT BETWEEN WHITESTONE REIT AND CHRISTINE MASTANDREA

THIS CHANGE IN CONTROL AGREEMENT (this “Agreement”) is made at HOUSTON, TEXAS, as of this 25^th day of August, 2014 (the "Effective Date"), between WHITESTONE REIT, a Maryland real estate investment trust (the “Company”) and CHRISTINE MASTANDREA, 1600 Post Oak Blvd., Unit 1307, Houston, Texas, 77056 (“Mastandrea”).

WHEREAS, Mastandrea holds the office of Vice President, Property Strategy and Market Research of the Company;

WHEREAS, Mastandrea has made and is expected to continue to make major contributions towards the profitability, growth, and financial strength of the Company;

WHEREAS, the Company’s shareholders have approved the 2008 LONG TERM INCENTIVE OWNERSHIP PLAN (the “LTIOP”), and awards of restricted common shares and restricted share units (“Awards”) under the LTIOP are integral to this Agreement (”Agreement”);

WHEREAS, the compensation committee (“Compensation Committee”) of the Company’s board of trustees (“Board”) has been authorized by the Board to implement, and has made Awards under the LTIOP in two phases, the 2008 Strategic Plan (“2008 Plan”), and the 2013 Strategic Plan (“2013 Plan”) collectively referred to as (“Plan”) and may make additional Awards in the future; and,

WHEREAS, the Company and Mastandrea desire to enter into this Agreement pursuant to which the Company will provide for payments, vesting of Awards and other benefits to Mastandrea upon the occurrence of a Change in Control, as defined in this Agreement;

NOW, THEREFORE, in consideration of the Company continuing to employ Mastandrea after the date hereof, the premises and the mutual covenants herein contained, the Company and Mastandrea agree as follows:

1.Contract Period. This Agreement shall be effective as of the date stated in the first sentence of this Agreement and shall continue until Mastandrea’s employment by the Company is terminated for whatever reason; provided, however that nothing in this Section 1 shall be construed in a manner to deny or abrogate Mastandrea’s entitlement to the payments and benefits described below in connection with a Change in Control of the Company as defined herein.

2. Compensation and Benefits; No Employment Agreement. Nothing in this Agreement shall be construed as an agreement to employ Mastandrea, and Mastandrea shall continue to serve as an officer and employee of the Company at the will and pleasure of the Company. Mastandrea’s employment by the Company may be terminated at any time by the Company’s chief executive officer, and she may be removed from the office of Vice President by the Board at any time. For such period as Mastandrea shall be employed by the Company, she will be entitled to such base salary (“Base Salary”), bonus or other cash incentive compensation (“Bonus”), which Bonus shall constitute “performance awards” pursuant to the LTIOP, as may be determined and approved from time to time by the Compensation Committee. Together, Base Salary and Bonus shall be referred to as “Annual Base Compensation.” In addition, Mastandre

a shall receive the awards under the Plan granted prior to the Effective Date, and may receive other awards under the Plan at such times and in such amounts as may be granted to Mastandrea by the Compensation Committee subsequent to the Effective Date, in each case subject to applicable vesting provisions as set forth in award agreements and/or the LTIOP. In addition, the Company may continue (but is not obligated) to provide Mastandrea with (a) health and welfare benefits to the same extent made available to employees generally, including family health insurance, travel accident insurance, life and accidental death insurance, and long term disability insurance, (b) directors and officers liability insurance, (c) full participation in any 401(k), profit sharing, pension or other retirement benefit plan (“Pension Plan”) either in place or that are put in place during Mastandrea’s employment, and (e) such other benefits that the Board may from time to time authorize.

To the extent that Mastandrea’s employment is terminated prior to a Change in Control on account of her death, by her voluntarily or by the Company for any reason or no reason, Mastandrea shall not be entitled to any payment of severance or continued provision of benefits by reason of this Agreement, it being intended by the parties that this Agreement only apply in the event of a Change in Control of the Company.

3.Definitions. A “Change in Control” shall have the meaning given to it in the LTIOP. For purposes of this Agreement, “Cause” for termination shall be deemed to exist if: (i) Mastandrea fails to devote the time and effort required for her to perform her duties hereunder; (ii) Mastandrea is convicted of a felony involving moral turpitude; (iii) Mastandrea engages in acts in violation of the confidentiality provisions of Section 5; or (iv) Mastandrea willfully, wantonly, and without approval of the Board (including, for this purpose, the Board of any successor to the Company) takes any action that she knows to be materially adverse to the interest of the Company and its shareholders, collectively. However, if any failure on Mastandrea’s part referred to in clause (i) or (ii) of the foregoing definition of Cause is curable, Cause shall not be deemed to exist for purposes of terminating Mastandrea’s employment unless the Company first gives her written notice specifying the nature of the failure and the steps that she must take to cure the failure, and Mastandrea fails to take those steps within 30 days after the notice is given. For purposes of this Agreement, “Good Reason” for Mastandrea to terminate her employment by the Company shall be deemed to exist if: (A) Mastandrea’s base salary is reduced below the amount in effect at the time of a Change in Control; (B) Mastandrea’s Bonus payment for the annual period first ending after the Change in Control is less than Mastandrea’s Bonus for the calendar year ending immediately prior to the Change in Control; (C) Mastandrea’s benefits are materially reduced from those Benefits in effect at the time of the Change in Control; (D) Mastandrea is removed from any of her offices or responsibilities or her duties with the Company are otherwise reduced to such an extent that she no longer has the same authority commensurate with her duties to the Company at the time of the Change in Control; or (E) Mastandrea’s principal place of employment for the Company is relocated outside of the Houston metropolitan area and, as a result, she is required to relocate. For purposes of this Agreement, Mastandrea’s employment shall be deemed to have been terminated by the Company “without Cause” if “Cause” is not deemed to exist as defined above or if James C. Mastandrea (“JCM”) shall cease to serve as Chairman of the Board and/or President and Chief Executive Officer of the Company on account of termination of JCM’s employment by the Company without cause, JCM’s termination of her employment for good reason and/or JCM’s failure to be renominated and/or re-elected as a member of the Board.

 

1.Payments upon Termination in the event of a Change in Control. If Mastandrea’s employment is terminated voluntarily by Mastandrea without Good Reason, involuntarily on

account of her death or disability, or by the Company for Cause after any Change in Control, then the Company shall pay to Mastandrea only the amounts described in subsection (a) immediately below. Otherwise, following any termination of Mastandrea’s employment with the Company within two (2) years after a Change in Control, the Company shall pay and provide to Mastandrea, after the date of the termination (the “Termination Date”), the amounts and benefits set forth below. For the avoidance of doubt, and notwithstanding any other provision to the contrary in any Award agreement (and this Agreement shall be deemed to amend any contrary provision in any such Award agreement), all unvested Awards shall immediately vest on the earliest date set forth in subsection (d) of this Section 4, and any restricted share units that so vest will be immediately exchanged for or converted into fully vested restricted shares of the Company.

(a) Termination by the Company or by Mastandrea for any Reason. Upon any termination of Mastandrea’s employment for any reason or for no reason, the Company shall pay to Mastandrea all accrued and unpaid Base Compensation, accrued Bonus and other benefits (e.g., accrued vacation) with respect to periods ending on or before the Termination Date.

(b) Termination by the Company without Cause, or by Mastandrea for Good Reason. If Mastandrea’s employment hereunder is terminated by the Company without Cause, or by Mastandrea for Good Reason, in addition to (but not in duplication of) all other compensation payable hereunder, the Company shall pay and provide to Mastandrea the following amounts and benefits:

(i) A lump sum cash payment of 1.5 times her Annual Base Compensation for the previous full calendar year.

(ii) Continuation of benefits as described in Section 2 for a period of one year.

(c) Full Satisfaction; Mitigation. Payment and provision of the salary and benefits to which Mastandrea is entitled under this Section 4 shall constitute full satisfaction of all obligations of the Company to Mastandrea arising under this Agreement and/or in connection with the termination of her employment. Payment or provision of the items set forth in Section 4(b) above shall be conditioned upon Mastandrea executing and delivering to the Company a release of all claims Mastandrea may have against the Company up to the date of termination.

 

(d)    Escrow Arrangement. To secure payment of the benefits provided for in this Section 4 the Company agrees to establish an irrevocable escrow account (the “Escrow Account”) at a national bank acceptable to Mastandrea (the “Bank”) promptly upon the earliest to occur of (i) Mastandrea’s receipt in writing of notice of termination of her employment upon a Change in Control, (ii) public notice of Change in Control, (iii) an agreement in principle to effect a Change in Control, or (iv) the date of consummation of a Change in Control (“Change in Control Date”). The amount of security required on deposit in the Escrow Account shall be the maximum cash amount that the Company would be required to pay to Mastandrea under Section 4.

The escrow amount established pursuant to this Section 4(d) shall be maintained on deposit in the Escrow Account until receipt by the Bank of written acknowledgement by Mastandrea that she has received all amounts payable to her by the Company under Section 4 or otherwise releases such amounts. Amounts deposited in the Escrow Account shall be paid out by the Bank only to Mastandrea or her designated beneficiary, in such amount as Mastandrea shall certify to the Bank as the amount she is owed by the Company and that the Company has not paid under Section 4 of this Agreement, or to the Company, to the extent that any amount remains on deposit in the Escrow Account after the Company shall have made all payments hereunder that it shall be obligated to make or until Mastandrea shall releas

e such amounts to the Company by written release. If any amount payable to Mastandrea pursuant to Section 4 is not paid by the Company or the Bank when due, interest on such payments shall accrue at the rate of one percent (1%) per month, or the highest rate allowed by law, whichever is lower, until all overdue payments are paid in full.

4.Confidentiality; Non-Competition. Mastandrea acknowledges that the business in which the Company is engaged is competitive and that her employment with the Company has required and will require that she have access to and knowledge of confidential and proprietary information pertaining to the Company’s operations and its properties (“Confidential Information”). Mastandrea shall not, during the term of her employment hereunder or at any time thereafter, except in connection with the performance of services hereunder or in furtherance of the business of the Company, communicate, divulge, or disclose to any other person not a Trustee, officer, employee, or affiliate of, or not engaged to render services to or for, the Company or use for her own benefit or purposes any Confidential Information that she has obtained from the Company during the term of her Employment under this Agreement, except that this provision shall not preclude Mastandrea from communication or use of Confidential Information made known generally to the public by any party unrelated to Mastandrea, or from making any disclosure required by applicable law, rules, regulations, or court or governmental or regulatory authority order or decree provided that, if practicable, Mastandrea shall not disclose any Confidential Information without first giving the Company notice of intention to make that disclosure and an opportunity to interpose an objection to the disclosure.

During the term of this Agreement and for a period of one (1) year after termination of Mastandrea’s employment following a Change in Control, Mastandrea shall not, directly or indirectly as an employee, officer, director, trustee, consultant, partner, member or shareholder (other than as a passive shareholder of less than 1% of the outstanding stock of a publicly-traded company), have any interest in or perform any services in respect of any property that meets the Company’s publicly-stated definition of a Community Centered Property within a five (5) mile radius of any property then-owned by the Company.

5.Merger or Transfer of Assets of the Company. The Company will not consolidate with or merge into any other entity, or transfer all or substantially all of its assets or shares to another entity, unless such other entity expressly assumes this Agreement in a signed writing and delivers a copy thereof to Mastandrea. Upon such assumption the successor entity shall become obligated to perform the obligations of the Company under this Agreement, and the term “the Company” as used in this Agreement shall be deemed to refer to such successor entity.

6.Notices. Notices and all other communications provided for in this Agreement shall be in writing and shall be deemed to have been duly given when delivered in person (to the Secretary of the Company in the case of notices to the Company and to Mastandrea in the case of notices to Mastandrea) or mailed by United States registered mail, return receipt requested, postage prepaid, as follows:
