Amendment to Executive Employment Agreement

On March 28, 2015, the Compensation Committee of the Board of Directors (the “Compensation Committee”) of Westwood Holdings Group, Inc. (the “Company”) approved an amendment (the “Amendment”) to the Executive Employment Agreement, effective as of May 1, 2010, between the Company and Brian O. Casey (the “Employment Agreement”). The Employment Agreement sets forth the terms under which Mr. Casey serves as the Company’s President and Chief Executive Officer and is annually nominated for reelection to the Company’s Board of Directors. The Amendment, which was executed on April 2, 2015, extends the term of the Employment Agreement, with the continuation of all of its current terms through December 31, 2015.

The foregoing descriptions of the Amendment and the Employment Agreement do not purport to be complete and are qualified in their entirety by reference to the complete texts of the Amendment and the Employment Agreement. The Amendment is attached hereto as Exhibit 10.1. The Employment Agreement was filed as Exhibit 10.1 to the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on April 23, 2010.

Restricted Stock Agreement

On March 28, 2015, the Compensation Committee approved a grant of 35,000 shares of restricted common stock (“Restricted Stock”) to Mr. Casey. The Company and Mr. Casey entered in a Restricted Stock Agreement covering the grant effective March 28, 2015. The shares of Restricted Stock will vest on or before March 1, 2016, subject to the terms of the Third Amended and Restated Westwood Holdings Group, Inc. Stock Incentive Plan and a performance vesting goal for fiscal year 2015 that was set by the Compensation Committee in the first quarter of 2015. The performance vesting goal is based on the Company’s “adjusted pre-tax income”, and is further described in the Restricted Stock Agreement. Upon the termination of Mr. Casey’s employment, any shares of Restricted Stock that have not vested will be forfeited, except (i) in the event of death, in which case all shares of Restricted Stock will vest, and (ii) as may be provided otherwise in the Employment Agreement.

The foregoing description of the Restricted Stock Agreement does not purport to be complete and is qualified in its entirety by reference to the complete text of the Restricted Stock Agreement, which is attached hereto as Exhibit 10.2.
