On December 5, 2012, the Company and Mr. Oppenheimer entered into a Separation Agreement and Release (the "Agreement") detailing the terms of Mr. Oppenheimer's separation. Consistent with his 2010 employment agreement, and upon the conclusion of Mr. Oppenheimer's employment in February 2013, Mr. Oppenheimer's will receive a severance payment equal to the sum of six months of his base salary, as well as 50% of his target annual bonus and an amount equal, on an after tax basis, to the aggregate COBRA premiums that Mr. Oppenheimer would otherwise pay for the twelve months following his separation from the Company if he timely elected COBRA. He also will have up to nine months to exercise any stock options that were vested at the time of his departure, as provided in his 2010 employment agreement. Except as noted above, there are no other compensation or severance benefits that will be earned or paid to Mr. Oppenheimer upon his departure, and all payments and benefits described above are subject to his not revoking his release agreement within the applicable statutory revocation periods.

The Company greatly appreciates the contributions Mr. Oppenheimer has made to ServiceSource.

On November 29, 2012, the Board of Directors (the "Board") of ServiceSource International, Inc.
