3 Update from Modernization & Upgrade Business within Europe Region Implementation First OFU6 - Upgrade on SGT5-4000F installed Two HCO Upgrades on SGT5-3000E installed Two asmc installed Seven 4000F and Six 2000E LTEs executed world wide New Orders SGT5-4000F Two OFU6 Packages One OFU7 Package Three asmc Upgrades Two GT Fast Load gradients One Premix Before Synchro Six Life Time Extensions New Orders SGT5-2000E One set Si3D stage 3-4 including Power Limit Increase Page

4 Changing energy market Challenges Generation side Consumer side Wind and solar power enter the market with huge capacities Financial crisis and Euro crisis impacting the economy Reduction of industry production / increase of efficiency Reduced power consumption Massive changes in fossil power generation profile (daily) Page

5 Changing energy market Opportunities LNG LNG terminals installed in Netherlands, UK and Spain leading to a broader sourcing base Unconventional Gas The USA have explored big resources of shale gas Gas price dropped within US market by 60% Reduction of gas prices expected over mid and long term improved competiveness for gas turbines USA started export of LNG to the world market Canada / Russia / Australia also start to explore their reserves Page
