H&P’s U.S. Land Activity and Pricing Comments H&P’s U.S. Land segment had approximately 84 contracted rigs generating revenue and approximately 79 rigs generating revenue days as of May 2, 2016 (~18% of the 79 rigs were idle and on standby dayrates). Average FlexRig spot pricing was down by more than 30%, as compared to spot pricing at the peak in November 2014. Since the start of the downturn in late-2014 through May 2, 2016, H&P’s U.S. Land segment had received early termination notices for 87 rigs working under long-term contracts, up three since March 22, 2016. (As of May 2, 2016)

As of May 2016 (~380 Active Rigs in U.S. Land) As of October 2014 (Peak) (~1,930 Active Rigs in U.S. Land) As of October 2008 (Peak) (~1,925 Active Rigs in U.S. Land) H&P’s U.S. Land Market Share Gains Market Leader 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 equal to or greater than 600 horsepower.

H&P Global Fleet Under Term Contract Strong Backlog The above term contract coverage excludes long-term contracts for which the Company received early contract termination notifications as of 5/2/16. Given notifications as of 5/2/16, the Company expects to generate over $80 million in the third fiscal quarter of 2016, about $20 million in the fourth fiscal quarter of 2016, and over $40 million thereafter from early terminations corresponding to long-term contracts. About 60% of the mentioned early termination revenues that we expect to be recognized after the second fiscal quarter of 2016 have already been invoiced and collected and are included in the current liability section of our March 31, 2016 balance sheet as deferred revenue. All of the above rig contracts include provisions for early termination fees. Some of the new build deliveries may be delayed in exchange for compensation from customers, but the corresponding total backlog would remain the same or potentially increase. Mutually beneficial renegotiations of some long-term contracts for active rigs are expected to extend the timing of those contracts beyond what is reflected above. *

Ongoing U.S. Land Market Trends Unconventional plays continue to shape the landscape. Customers continue to focus on drilling efficiency, technology and safety. AC drive rigs are best suited for more complex horizontal drilling. Multiple wells being drilled from a single pad. The replacement cycle is expected to continue.

Increasing Focus on More Difficult Drilling
