The Drilling Market Today Our operational outlook for the fourth fiscal quarter remains unchanged. Assuming commodity prices hold, we expect some improved traction in U.S. land active rig count. Absent overall improvement, we expect AC drive, Tier 1 rigs to continue to gain market share. Helping to capture efficiency gains for customers continues to differentiate our performance.

Announcing Seven Additional New Builds Multi-year term contracts with three customers to build and operate seven incremental FlexRigs in the U.S. Like previously announced contracts, these new contracts are expected to generate attractive economic returns for the Company. As of October 1, 2013, six announced FlexRigs remain to be delivered. Once these rigs are completed, the Company’s global fleet is expected to include 308 FlexRigs.

U.S. Land Market Trends Spot market pricing is firm. We continue to enter into additional term contracts with customers. We are encouraged by recent customer discussions indicating a potential increase in activity. Included in recent customer discussions are inquiries about additional new builds under term contracts with attractive dayrates.

H&P’s New Build Program Continues We are positioned to quickly respond to opportunities and take advantage of an improving market landscape. H&P plans to continue a build cadence of two rigs per month through the rest of the calendar year. We have the flexibility to build required capital spares or convert those into new FlexRigs.

FlexRigs Delivering Drilling Efficiencies We have over 1,200 rig years of AC Drive FlexRig drilling experience. Drilled over 52 million feet in 2012 Drilled in excess of 40 million feet in first eight months of 2013 Improved our footage per day by 23% between 2011 and 2012 Footage per day has increased approximately 14% in 2013

Performance is Not Only About Better Rigs Our competitive advantage is also about: People Safety Experience Training Culture Support Structure Processes Organizational Network Maintenance Supply Chain

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

High-Grading is Accelerating 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.

Unconventional Plays Shaping Landscape Well Complexity is increasing: Horizontal and directional wells make up over 75% of wells drilled in the U.S. 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

H&P’s Pad Capable Fleet Approximately 50% of H&P’s active feet, all of which are AC drive rigs, are equipped with hydraulic pad systems. Our pad capable fleet is fully utilized. In addition, we continue to add new pad capable FlexRigs and have customer interest in additional pad drilling system upgrades for existing FlexRigs.

FlexRigs Leading in Pad Drilling Efforts AC Drive FlexRigs lead in pad drilling efforts in U.S. Land FlexRig3 first pad application in 2004 FlexRig4 was the first bi-directional land drilling design FlexRig5 is the latest generation of bi-directional, long lateral pad drilling rig We have drilled over 6,700 wells on approximately 1,350 pads
