Announcing Five Additional New Builds Five incremental FlexRigs with multi-year term contracts with two customers in the U.S. Since the beginning of fiscal 2014, we have now announced term contracts for 18 new FlexRigs with six customers in the U.S. As of December 11, 2013, six of the 18 announced FlexRigs have already been delivered. Once the remaining rigs are completed, the Company’s global fleet is expected to include 319 FlexRigs.

H&P’s U.S. Land Operations We now expect total quarterly revenue days to increase by approximately 4% (up from our prior estimate of 3%) during the first fiscal quarter of 2014 as compared to the fourth fiscal quarter of 2013. We still expect average rig revenue per day, excluding early termination and delay revenues, to decline by less than 1% during the first fiscal quarter of 2014 as compared to the fourth fiscal quarter of 2013. Approximately $10 million in early termination and delivery delay revenue is still expected in the first fiscal quarter of 2014. We still expect average rig expense per day to be roughly $13,000 (with a range of plus or minus a few percentage points) in the first fiscal quarter of 2014. Drilling Operations Outlook for the First Quarter of Fiscal 2014

H&P’s Offshore Operations We continue to expect the number of revenue days during the first fiscal quarter of 2014 to be flat as compared to the fourth fiscal quarter of 2013. We now expect the average rig margin per day to result in approximately $26,000 per day during the first fiscal quarter of 2014 (up from our 11/14/13 estimate of approximately $25,000). Drilling Operations Outlook for the First Quarter of Fiscal 2014

We still expect revenue days during the first fiscal quarter to decline by approximately 10% as compared to the fourth fiscal quarter of 2013. Average rig margin per day is still expected to be relatively flat during the first fiscal quarter of 2014 as compared to the previous fiscal quarter.

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

Increasing Focus on More Difficult Drilling U.S. Rig Activity by Drilling Type Percentage of Active U.S. Rigs (BHI North American Rotary Rig Count)

H&P’s Lead in U.S. Land AC Drive Rigs Note: The above estimates corresponding to U.S. lower 48 AC Drive fleets are derived from Rig Data and corporate filings.

FlexRigs Delivering Drilling Efficiencies We have approximately 1,300 rig years of AC Drive FlexRig drilling experience. Drilled over 52 million feet in 2012 Drilled in excess of 56 million feet through November 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

U.S. Land Market Trends Firm spot market pricing. Continued customer focus on drilling efficiency, technology and safety. We believe that differentiated performance delivers tangible value and will be rewarded accordingly. We continue to have conversations with customers for additional new build orders.

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

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

H&P’s Pad Capable Fleet Approximately 50% of H&P’s U.S. Land active fleet, 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.

(273 H&P Contracted Land Rigs as of 12/11/13*) Leading U.S. Unconventional Driller * Includes 12 announced new FlexRigs with customer commitments scheduled for delivery in calendar 2013 and 2014.

H&P’s New Build Program Continues H&P plans to continue a build cadence of two rigs per month through the rest of the fiscal year. We have the flexibility to increase our production cadence depending on market demand. We believe that this approach will continue to reward shareholders.

Record Profits During Industry Slowdown ** NBR’s operating income corresponds to its U.S. Lower 48, U.S. Offshore, and Alaska business units. * PTEN’s operating income includes drilling operations in Canada.

Return on Equity * Including gains from the sale of investment securities and discontinued operations, H&P's corresponding ROE resulted in 17.8%. ** The corresponding ROE values for the selected companies exclude certain extraordinary, non-recurring charges.
