Amendment to Employment Agreement with Gregory R. Liberman

On October 17, 2013, Spark Networks, Inc. (the “Company”) and Gregory R. Liberman, the Company’s President and Chief Executive Officer, entered into Amendment No. 2 (the “Amendment”) to his Executive Employment Agreement, which was originally entered into on April 11, 2011 and amended by Amendment No. 1 on December 20, 2012 (together, the “Agreement”). The Amendment alters certain of Mr. Liberman’s benefits upon termination and a change of control of the Company.

The Amendment specifies that upon termination by either party, for any reason, Mr. Liberman will receive his prorated base salary earned as of the date of termination, plus any accrued unused vacation and the amount of any annual bonus earned but unpaid for performance for the fiscal year of the Company ended before the date of Mr. Liberman’s termination.

The Amendment alters the terms of the single cash lump-sum severance payment Mr. Liberman will receive if he is terminated without cause or if he leaves for good reason. Pursuant to the Amendment, the single cash lump-sum severance payment will consist of 100% of his base salary plus (i) 50% of his target annual bonus, if the termination occurs on or prior to June 30th of the fiscal year, or (ii) his target annual bonus, if the termination occurs on or after July 1st of the fiscal year. If the termination of employment without cause or for good reason occurs at any time on or after the date of a change of control of the Company, the single cash lump-sum payment will consist of 200% of Mr. Liberman’s base salary plus (i) 50% of his target annual bonus, if the termination occurs on or prior to June 30th of the fiscal year, or (ii) his target annual bonus, if the termination occurs on or after July 1st of the fiscal year.

Solely for purposes of determining the single cash lump-sum severance payment upon a termination without cause or upon Mr. Liberman’s departure for good reason, the definition of change of control was amended to include the situation where during any period of 24 consecutive months the directors serving on the Company’s board of directors at the beginning of such period cease to constitute at least a majority of the members of the board.

The Amendment also provides for full vesting of all of Mr. Liberman’s outstanding, unexercised options as of the date of a change of control of the Company without regard to an obligation to provide continued employment to the successor company.

The Amendment is effective October 17, 2013. There were no other changes to Mr. Liberman’s Employment Agreement. A copy of the Amendment is attached as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated by reference herein. The description of Mr. Liberman’s Amendment in Item 5.02 of this Current Report on Form 8-K is qualified in its entirety by the terms of the Amendment.
