The U.S. Land Drilling Market Today Our operational outlook for the third fiscal quarter remains unchanged. Oil price resiliency will probably accommodate gradual growth in activity as we move through 2013. Customers are deliberate with their budget dollars and increasingly discriminating with the service providers they engage. Customers continue to shift into a developmental phase of their drilling projects where consistency, performance, safety and additional efficiency capture all become important differentiators.

H&P’s U.S. Land Fleet Activity (1) (2) (1) Active rigs on term (in blue) generated both revenue and revenue days. (2) Includes completed new builds pending delivery and not generating revenue days.

H&P’s Pad Capable Fleet As of 6/14/13, H&P had a total of 113 pad capable FlexRigs, all of which are AC drive rigs. In addition, we continue to add new pad capable FlexRigs and have customer interest in additional pad drilling system upgrades for existing FlexRigs. We have drilled over 5,000 wells on approximately 1,000 pads since 2005.

H&P’s New Build Program Continues We believe that the rig replacement cycle will continue for several years. H&P plans to continue a build cadence of two rigs per month through the rest of the calendar year, increasing our fiscal 2013 capex estimate to $890 million. We have the flexibility to build required capital spares or convert those into new FlexRigs.

The Replacement Cycle Continues As of October 2008 (Peak) (~1,900 Active Rigs in the U.S. By Power Type) As of May 2013 (~1,600 Active Rigs in the U.S. By Power Type) Note: The above estimates corresponding to rig activity are derived from multiple sources including Rig Data, Smith Bits, and corporate filings. Additionally, the drawworks capacity of each land rig included in the above analysis was greater than 600 horsepower. Certain assumptions were made on approximately 5% of the active rigs that were not readily identified.

H&P Continues to Capture Market Share As of October 2008 (Peak) (~1,900 Active Rigs in the U.S.) As of May 2013 (~1,600 Active Rigs in the U.S.) Note: The above estimates corresponding to market share are derived from Rig Data. PDS’ market share includes both PDS and Grey Wolf rigs. Additionally, the drawworks capacity of each land rig included in the above analysis was greater than 600 horsepower.

Favorable Market Trends for FlexRigs AC drive rigs replacing SCR and mechanical rigs More customers high-grading their fleets Increasing well complexity Expectation to drill more wells with fewer rigs Focus on drilling efficiency, technology and safety

Increasing Focus on More Difficult Drilling

Unconventional Plays Shaping Landscape Well Complexity is increasing: Technology solutions that provide safe, environmentally sound and efficient operations are required by contractors to be competitive Extended reach laterals progressively longer Multi-well pad drilling gaining acceptance in more areas A factory approach to drilling wells is required This all creates an expanding level of demand for FlexRigs
