Summary • Construction project is ~83% complete (earned value) – – Confident in the quality of completion plans Conservative baseline plan for additional drilling years Materials and labor costs are well understood Continuous attention to safety and technical performance • Operations formally underway • Restoring strings as originally planned – Plans in place for 80 Strings/Ice. Top Stations – Plan to replace AMANDA with 6+ Strings May 5, 2008 Ice. Cube SAC Meeting May 2008 13
