A Quick Primer on Helmerich & Payne Primarily focused on the contract drilling business with approximately 10,000 employees Provides services for oil and gas companies on a dayrate basis Market share leader with the most modern and capable fleet in the U.S. land drilling business Three primary segments (and percentage of operating income year to date): U.S. Land (~94%) Offshore (~4%) International Land (~2%) Internally designs, builds and operates its own rigs (FlexRigs) Leads the industry’s replacement cycle with over 220 new AC drive FlexRigs deployed under long-term contracts since 2006 Strong balance sheet

Well Positioned in the U.S. Land Market While both oil and gas prices have recovered some lately, the $100 question focuses on what happens next, particularly in terms of the future price of oil. The volatility and uncertainty appear to be weighing on the minds of our customers, impacting their budgeting decisions and their spending in the field. While industry rig counts are declining and spot pricing is softening, our sense is that the duration and depth of this slowdown will be on the milder side. Nevertheless, we are well positioned for the uncertainty ahead: About two thirds of our active fleet are under long-term contracts We already have in place today an average of: 138 FlexRigs under term contracts during fiscal 2013 95 FlexRigs under term contracts during fiscal 2014 These rigs are expected to generate average daily rig margins that are higher than the average reported in the segment during the third quarter of fiscal 2012.

Our New Build Efforts We are not only the most active driller in the U.S. land market, but also continue to have a very significant lead in the growing segment of advanced technology AC drive rigs. We have continued to make new build deliveries on time and on budget, including six new FlexRigs since our last webcast. We have 19 rigs under construction with long-term contracts that are scheduled to continue to roll off at the rate of four per month through early calendar 2013. The commodity price volatility and uncertainty we are discussing today has further quieted conversations regarding new build orders; customers appear to have taken a wait and see approach. We do not believe that the replacement cycle is over, and our approach will be to make sure that our supply chain is ready to respond to incremental demand on a timely basis. Our integrated effort affords us an important flexibility that should serve us well.

U.S. Land Market Conditions Increasing well complexity and greater focus on technology and safety continue to favor advanced technology AC drive rigs. About two thirds of our active rigs are under term contracts and 97% of our rigs in the spot market are advanced technology AC FlexRigs. Nonetheless, activity has continued to decline and the number of revenue days during the fourth fiscal quarter is now expected to be slightly down (by ~1%) as compared to the third fiscal quarter. Even with softening dayrates in the spot market, we expect average rig revenue per day to be roughly flat as we transition from the third to the fourth fiscal quarter (excluding early termination revenue of ~$7 million). Average rig expense per day is expected to be in the $13,500 to $13,800 range during the fourth fiscal quarter.

The Replacement Cycle Continues AC drive rigs are best positioned to make the transition. Older, underperforming rigs are more likely to be sidelined. Since the 2008-2009 downturn, approximately 300 rigs have permanently stacked, and about 70% of these were mechanical rigs. Advanced technology AC drive rigs continue to displace mechanical and SCR rigs.

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

H&P’s New Build Advantages We have been improving and honing the process for over 10 years, prompting our assertion that we build a better rig for less Safety is our first priority, followed by a relentless focus on strong execution and performance in the field Exceptional fleet uniformity Extensive collaboration with customers and suppliers A strong organizational orientation to consistent, repeatable, field execution

Performance is Not Only About Better Rigs It’s also about: People Safety Experience Training Culture Support Structure Processes Organizational Network Maintenance Supply Chain

H&P Competitive Advantages Our people, processes and FlexRig technology create a very important competitive advantage for the Company. Our value proposition will continue to be directed toward delivering compelling performance for our customers and shareholders. The shift to drilling more complex unconventional resource plays that require the drilling of horizontal and directional wells only magnifies our competitive advantage. 37

H&P’s Offshore Operations Our offshore operations outlook for the fourth fiscal quarter remains unchanged. Seven of the Company’s nine offshore platform rigs remain active, and one of the two stacked rigs began mobilizing in August. In the fourth fiscal quarter, we expect revenue days to increase by ten to 15 percent as compared to the third fiscal quarter. Average rig margin per day is expected to increase by 15 to 20 percent during the fourth fiscal quarter of 2012 as compared to the third fiscal quarter.

H&P’s International Land Operations Our international land operations outlook for the fourth fiscal quarter remains unchanged. Of the 29 rigs assigned to international operations, 25 are currently active. Total revenue days during the fourth fiscal quarter are expected to increase five to ten percent from the third fiscal quarter of 2012. Average rig margin per day is still expected to decrease by ten to 15 percent during the fourth fiscal quarter of 2012 as compared to the third fiscal quarter.
