Board Proactively Adopted Proxy Access 7 The Board Urges Shareholders to Vote AGAINST the Shareholder Proposal for Proxy Access at 3%/3years After considering the views of our largest stockholders and market practices, the Board designed and implemented a proxy access by-law deemed most appropriate for The Priceline Group Rationale For Adopted Thresholds Our Proxy Access By-Law Already in Place Proxy Access right should be given to long-term holders of a significant ownership stake Right should be transparent to the Company and all shareholders Right should be used to promote the best long-term interests of shareholders not short-term objectives Right generally is to be used after shareholder(s) have engaged the company in discussions Right should be proportional to ownership stake of nominating shareholder(s) Right is meant as tool for addressing a board that is unresponsive, not as a means for change in control Proxy access by-law:  Our by-law provides that holders of 5% of shares continuously for 3 years (including a group of up to 20 shareholders) may place “proxy access” nominations directly on the company proxy card; nominating groups in aggregate may nominate up to 20% of the board In order to ensure a sense of proportionality:  A stockholder or group owning > 5% but < 10% of common stock for a 3 year period can nominate up to 10% of the numbers of directors then serving (but at least one)  A stockholder or group owning > 10% of common stock for a 3 year period can nominate up to 20% of the number of directors then serving
