ServiceSource International, Inc. (the "Company") announced today that Jeffrey M. Bizzack will become Vice Chairman of the Company, effective October 5, 2012. As a result, Mr. Bizzack will leave his position as President of the Company, also effective October 5, 2012. Mr. Bizzack will remain in the Vice Chairman role until June 30, 2013 or such later date as he and the Company may agree. Mr. Bizzack joined the Company in August 2009, and has been instrumental in driving the Company's growth and expansion over the past three years. Mr. Bizzack's change of title and role does not involve any controversy or disagreement with the Company.

On October 5, 2012, the Company and Mr. Bizzack entered into a Separation and Consulting Agreement and Release (the "Agreement") detailing the terms of Mr. Bizzack's transition and services to be provided to the Company. The Agreement acts as an amendment to Mr. Bizzack's existing employment agreement with the Company dated as of October 20, 2010 (the "Employment Agreement") as described below. Under the Agreement, Mr. Bizzack will remain a full-time employee through December 31, 2012. Beginning January 1, 2013, Mr. Bizzack will serve as Vice Chairman in a consulting capacity. Mr. Bizzack will continue to receive his same level of compensation and benefits through December 31, 2012, and will remain eligible to receive any bonus earned under the 2012 Corporate Incentive Plan pursuant to its terms if and when the Company pays out a bonus under such plan. Mr. Bizzack also will be eligible to receive health insurance reimbursement from the Company for up to three months after his employment ends. During the term of the consulting period, Mr. Bizzack will continue to vest in his equity awards and, upon the termination of all of his services to the Company, his equity awards will remain exercisable for the standard 90 day period. In addition, pursuant to the Agreement, if the Company terminates Mr. Bizzack's employment prior to December 31, 2012 without "cause" (as defined in Employment Agreement) or if the consulting services are terminated prior to June 30, 2013 by the Company for any reason other than "cause," Mr. Bizzack's outstanding equity awards will have their vesting accelerated to June 30, 2013. In addition, the Agreement provides for Mr. Bizzack to sign a customary release of any and all claims at the time of his separation from employment and at the termination of his consulting period. Other than as noted above, there are no other compensation or severance benefits that will be earned or paid to Mr. Bizzack under the Agreement or the Employment Agreement.
