Form 8-K SERVICESOURCE INTERNATIO For: May 21

________________

"In 2014, I continued to work as ServiceSource's Chairman of the Board in order to usher ServiceSource into a new era where we would expand upon its market-leading position serving the world's most prominent B2B brands," said Smerklo. "When the Board named Christopher Carrington as ServiceSource's new CEO, I worked closely with him to ensure a smooth transition and since his appointment I could not be more pleased with the strategy and vision he's brought to ServiceSource. After more than twelve years working with ServiceSource, I am proud of what the team has achieved building on top of our strong foundation and I look forward to seeing ServiceSource's continued success under Christopher's leadership."

Smerklo's resignation will be effective as of the closing of the company's annual shareholder meeting on May 28, 2015.

"On behalf of the Board and the ServiceSource management team, I want to thank Mike for his incredible leadership and many contributions to the company over the past twelve years," said Carrington. "Mike was instrumental in establishing this company as the global leader in recurring revenue and developing enduring customer relationships that have paved the way for ServiceSource's continued success. I look forward to building on the foundation he established as we now take a leading role in the market for revenue lifecycle management solutions."
