STARBOARD DELIVERS OPEN LETTER TO LIVEPERSON STOCKHOLDERS

Highlights the Company's Troubling Corporate Governance Practices and the Board's Lack of Relevant Experience and Ineffective Oversight

Views the Company's Decision to Delay the Annual Meeting in Order to Make Reactionary Changes as a Transparent Effort to Defend the Status Quo and Entrench the Board

Remains Open to Engaging in Constructive Settlement Discussions Which Would Include Providing Access to Its Nominees for Interviews Following an Understanding on an Appropriate Level of Board Change

Believes a Reconstituted Board with Starboard's Highly-Qualified Nominees Would Bring Much Needed Industry and Public Company Board Expertise and Improved Diversity to the Board
