On March 7, 2013, the Board of Managers (the “Board”) of ALST Casino Holdco, LLC (the “Company”) appointed Robert Schaffhauser, 66, as the Chief Financial Officer of the Company. Mr. Schaffhauser has served as the Chief Financial Officer of Aliante Gaming, LLC (“Aliante Gaming”), the Company’s wholly owned subsidiary, since December 27, 2012. Mr. Schaffhauser previously served as Executive Vice President of Finance for Colony Resorts LVH Acquisitions, LLC (which previously owned and operated the Las Vegas Hilton) from February 2004 to March 2012, where he was responsible for business planning and administrative functions (including finance, accounting, legal, human resources, information technology and purchasing).

Effective December 27, 2012, Aliante Gaming entered into an employment agreement with Mr. Schaffhauser (the “Schaffhauser Employment Agreement”). Pursuant to the Schaffhauser Employment Agreement, Aliante Gaming agreed to employ Mr. Schaffhauser for an initial term of one year with an effective commencement date of December 27, 2012. The initial term will be automatically renewed for subsequent one-year terms unless the Schaffhauser Employment Agreement has been terminated in accordance with its terms or either party provides the other with notice of non-renewal at least 90 days prior to the expiration of the then applicable term. The Schaffhauser Employment Agreement provides for a base salary of $250,000 per year (“Base Salary”), and a performance bonus of up to thirty-five percent (35%) of the Base Salary based upon the Company’s actual performance in relation to its budgeted performance, subject to the discretion of the Board. Mr. Schaffhauser is eligible for fully vested and paid equity in the Company of up to fifty percent (50%) of the amount of any performance bonus approved by the Board. The valuation of such equity shall be determined by the Board. The Schaffhauser Employment Agreement also provides certain additional benefits and perquisites made generally available to the management of Aliante Gaming.

In the event of termination of Mr. Schaffhauser’s employment without cause, Mr. Schaffhauser is entitled to a termination payment equal to the greater of (i) the portion of the Base Salary for the remainder of the then applicable employment term or (ii) three months of the Base Salary in the event Mr. Schaffhauser is terminated within the last two months of the then applicable employment term, in each case, including the performance bonus, if applicable, prorated based upon the number of days of his employment during the year of termination.

Pursuant to the Schaffhauser Employment Agreement, Mr. Schaffhauser has agreed to certain restrictive covenants during the term of his employment and for specified periods following termination, including but not limited to, not divulging confidential information, assigning all intellectual property conceived or developed by Mr. Schaffhauser during the term of his employment with Aliante Gaming, non-competition and non-solicitation. Mr. Schaffhauser cannot engage in competition with Aliante Gaming, or own any interest in or perform any services for certain businesses engaged in competition with Aliante Gaming, within a specified restricted area and during a specified restriction period.

The foregoing summary of the Schaffhauser Employment Agreement does not purport to be complete and is subject to and qualified in its entirety by the full text of such agreement, which is attached as Exhibit 99.1 hereto and incorporated herein by reference.
