SummaryQ&A 5 Summary financial guidance

EDC Overview . Our expected total drilling volume for 2012 is at least 5.8 million meters

. Pricing in ruble terms has increased by 5-7% on average

Summary . Onshore horizontal drilling volumes for FY 2012 are now expected to be roughly equal to our 2011 total at approximately nine hundred thousand metres

. Onshore drilling services revenues are expected to grow in line with our backlog; sidetracking, workover and offshore drilling revenues are also expected to grow at a similar pace

Investment Case . For the full year 2012, revenue guidance is US $3.15 billion

. While 2011 saw significant changes to our services mix, we do not expect major variations in the ratio of conventional to horizontal drilling in 2012
