 Rigs across the board, including FlexRigs, continue to quickly become idle Next stage will entail a sorting process focused on capturing efficiencies It is too early to call at this stage when that sorting process will occur The Market Today

 U.S. Land The rig count continues to decline 132 of 196 rigs are currently contracted, 102 of which are under long-term contracts Customers have early terminated about 9% of our remaining contracted revenue days We expect to invoice most of the corresponding fees (over $100 million) in fiscal 2009 A total of 48 H&P rigs previously in the spot market are now idle (including 22 FlexRigs) A total of 16 of 28 FlexRigs with term contracts that were early terminated are now idle The number of idle rigs (currently 64) is expected to be at least 83 by quarter-end International Land No progress in terms of receivable collections from PDVSA Will continue with previously stated approach as rig contracts expire in Venezuela Market conditions in international markets are softening – eight H&P rigs are now idle Nine of 32 total rigs are on term contracts (including eight FlexRigs) Offshore 100% utilization today Strong margins Possible softening in second half of fiscal 2009 H&P’s Three Drilling Segments

New Builds – H&P’s FlexRig Program The FlexRig Difference: Key Advantages Increased drilling productivity and reliability Variable frequency (AC) drives with increased precision and measurability Computerized electronic driller that precisely controls weight on bit, rotation and pressure Designed to move quickly from well to well Accelerated well programs and NPV gains A significantly enhanced and safer workplace Minimized impact to the environment Total well cost savings even at premium dayrates

 Performance is not only about better rigs It’s also about: People Safety Experience Training Culture Supply chain Maintenance Processes Organizational network Support structure A Strong Field Organization
