Amendment to Employment Agreement with Gregory R. Liberman

On December 20, 2012, the Company and Gregory Liberman entered into an amendment (the “Amendment”) to his Employment Agreement, which was originally entered into on April 11, 2011. The Amendment increases Mr. Liberman’s base salary from $325,000 to $375,000 per year and his target annual bonus from $225,000 to $250,000. The Amendment is effective January 1, 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 Agreement.

Option Grant

On December 17, 2012, Mr. Liberman received a grant under the Company’s 2007 Omnibus Incentive Plan of an aggregate of 300,000 stock options. 100,000 of the stock options have an exercise price of $7.40 per share, 100,00 stock options have an exercise price of $8.00 per share and 100,000 stock options have an exercise price of $10.00 per share. 1/36^th of the stock options granted will vest on each monthly anniversary of the date of grant such that the options granted will become fully vested on the three year anniversary of the date of grant. The stock options have a term of 10 years and are exercisable for one year following Mr. Liberman’s termination of employment.

Similar to previous options granted to Mr. Liberman, upon a change in control of the Company, all of Mr. Liberman’s unvested stock options will immediately vest. However, if a successor company retains Mr. Liberman for the one-year period following a change in control then any proceeds received by Mr. Liberman with respect to 50% of Mr. Liberman’s options, the vesting of which was accelerated by the change in control, will be deposited in escrow to be released upon the earlier of (x) the one year anniversary of employment by the successor company, (y) if Mr. Liberman is terminated for any reason except for cause by the successor company or without good reason by Mr. Liberman and (z) upon a change of control of the successor company. The escrow will be forfeited if, during that one year period, Mr. Liberman is terminated for cause or if he leaves without good reason. A change in control is the acquisition of 50% or more of the total voting power of the Company’s voting securities, the disposition of all or substantially all of the Company’s assets, the liquidation or dissolution of the Company, a merger, consolidation, or similar transaction other than a business combination that would result in the voting securities of the Company outstanding immediately prior to such a transaction continuing to represent at least 50% of the total voting power represented by the voting securities of the Company or such surviving entity and a repurchase or recapitalization of the Company’s securities.
