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

Value Proposition Example – H&P vs. Competitors Estimated Field H&P FlexRig3 Competitor Average 2008 1. Drilling days 13 7.8 Completion days 2 2 Moving days 5 3 Total rig revenue days per well 20 12.8 2. Drilling contractor dayrate $19,500 $26,500 Operator’s other intangible $15,000 $15,000 cost per day estimate Total daily cost estimate $34,500 $41,500 Total cost per well (daily services) $690,000 $531,200 3. Total well savings with H&P – per well $158,800 per year $4.5MM

 Value added from FlexRig operations Significant H&P dayrate premium Increased wells per rig per year: 10.3 wells Early production: Incremental wells on production Lowest total well cost Value Proposition Example – H&P vs. Competitors

 U.S. land industry rig counts and spot dayrates continue to decline. 165 out of 192 H&P rigs were active as of 1/9/09, including 112 rigs under term contracts. Since the peak in November, average spot dayrates for H&P rigs have declined by an average of 10% to 15% per rig category. The segment had 24 idle rigs as of 12/31/08, approximately 30 idle rigs currently, and potentially over 40 idle rigs by the end of January 2009. H&P’s U.S. Land Operations

 16 of 35 (46%) of H&P’s conventional rigs (including highly mobile) in the spot market were idle as of 1/9/09. Eight of the 42 (19%) FlexRigs previously active in the spot market were idle as of 1/9/09. In addition, two FlexRigs built after 2005 with long-term contracts and one previously existing FlexRig also with a long-term contract have recently received early termination notice and will receive early termination fees. Approximately 56% of the segment’s potential revenue days corresponding to the remaining three quarters of fiscal 2009 are currently under term contracts. H&P’s U.S. Land Operations (Continued)

 25 of 28 international land rigs are currently active, including four FlexRigs An additional four new FlexRigs with long-term contracts have been completed and are expected to be deployed in fiscal 2009 Actively seeking additional growth opportunities around the world H&P’s International Land Operations

 Strong daily margins Eight of nine rigs are currently active The ninth rig is contracted and expected to begin operations in early to mid 2009 H&P’s Offshore Operations

 Long-term contracts – Over half of our potential U.S. land revenue days during the remainder of fiscal 2009 are already contracted with attractive dayrates Nearly two-thirds of H&P’s rigs in the U.S. land spot market are FlexRigs Customer base – About 80% of our U.S. land fleet is operated by majors and very large independents Strong Balance Sheet – Debt-to-cap ratio under 20% Well Positioned to Cope with Market Volatility
