Original Detector Baseline 70 vertical strings plus surface stations 4,480 Digital Optical Modules (DOM) 60 DOM/string spaced between 1450 and 2450 meters 2 DOM/surface tank and 2 tanks at each surface location Integrate AMANDA Instrumented volume of ≤1 km3 of ice Software and computing required to commission and operate the detector May 5, 2008 IceCube SAC Meeting May 2008

Cost & Schedule Baseline Baseline (Hartill 02/04) Current (04/08) Cost: TPC $271.8 million $276.6 million NSF $242.1 million $242.1 million unchanged Foreign $ 29.7 million $ 34.5 million Earned Value: $220.0 million (83%) Contingency: $ 40 million (22%) $ 10.5 million (24%) Most of the Technical Risk Retired Schedule: 4th Quarter, 2010 2nd Quarter, 2011 May 5, 2008 IceCube SAC Meeting May 2008

2007/08 Season Excellent planning, shared commitment, and consistent positive results Solid basis for future planning 50% of total instrumentation installed M&O mode of operations Safety must continue to be the highest priority Opportunities for improvement will be pursued May 5, 2008 IceCube SAC Meeting May 2008

Projected Contingency

M&O Funding & Tracking

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/IceTop Stations Plan to replace AMANDA with 6+ Strings May 5, 2008 IceCube SAC Meeting May 2008
