USS - Technology & Innovation Driving Superior Growth Note: USS was acquired 2H 2004 Source: Spears OMR 2010 23 Drill Bit Market 2005-'11 CAGR 9.7%

Diamond Drill Bit Inserts do the Difficult Cutting Work at the End of the Drillstring Fixed cutter bit & inserts Rolling cone bit & inserts Percussion bit & inserts US Synthetic Products Customers' Products 24

Proprietary HPHT Presses are Key to Making High-performance Drill Bit Inserts Diamond Grit Tungsten-Carbide Substrate Diamond Insert High Pressure High Temperature Cubic Press Process Conditions Pressure: 1 million psi (Similar to the Eiffel Tower , upside down on a 5" plate) Temperature: 1400° C (Higher temperature than molten lava) 25

All downhole drilling technologies depend on cutter performance PDC TECHNOLOGY IS A COMPLEX OPTIMIZATION OF CHARACTERISTICS NEEDED FOR DRILLING Wear life, Impact strength, Thermal stability The pace of development is extremely rapid, given the challenge we face Each customer expects 2-6 new products for evaluation every year Performance improvements demanded by customers typically come with added manufacturing complexity We compete for the business daily on the basis of the technology we provide We have an 'Engineering Force', rather than a 'sales force' Our engineers work directly with our customers' engineers to develop products Each bit and drilling application is unique - Ability to provide rapid customized solution is a major competitive advantage for us Cutter performance, measured every day, on every rig, is key to the success of the drilling operation. 26

Drill Bits are a Small Portion of Drilling Costs, but can Deliver Substantial Savings Source: US Synthetic Estimates 27

While diamond inserts on the drill bit represent less than 1% of the drilling cost, they can save the operator hundreds of thousands of dollars. A Gulf of Mexico example: Diamond Inserts An Example of the Savings that PDC Inserts on Fixed Cutter Bits can Deliver 28

Difficult Drilling & PDC Adoption Have Driven Growth of PDC Bits and PDC Inserts Source: Spears & Associates 29

In drilling, the best performance wins. We re-win our business every day. Recent share gains are a result of a faster innovation cycle and improved product performance. When our customers win and gain share, we gain share against our competition indirectly. We've been gaining share directly and indirectly over the past several years. PDC bits displace traditional rolling cone bits: Diamond cutting structure replaces steel and tungsten carbide. Result of improved PDC durability and better bit stability. Increased PDC bit use in shale plays and horizontal drilling, both of which are growing. Better rigs, increased motor, steering tool use favor PDC Growth Drivers Technology Adoption Share Gains Advances in drilling technology and improved diamond insert technology offer growth in excess of drilling activity levels 30

Current estimated share Room for growth in N.A. China/Russia illustrate E. hemisphere opportunity Share 24 months ago A Lot of Room to Grow: Continued PDC Adoption, Technology Leadership Source: US Synthetic Estimates Source: Spears & Assoc., US Synthetic PDC Adoption Share Gain 31
