6. Key Revenue Drivers: Day Rates: The rate that driller charges an operator for each day over contract period for the use of rigs Utilization Rate: The actual percentage of time in a year a rig would be utilized • Both variables mentioned above depend on exploration expenditures set by oil and gas companies which in turn depend on Political, Regulatory and Economic factors • Availability of rigs in an area of potential exploration also affects day rates and utilization rates

13. Industry Outlook • Oil and gas exploration industry grew at a healthy rate from 2005-2007. • The global economic crisis has led to rapid fall of prices in 2009. • Sector production volumes increased with a compound annual growth rate (CAGR) of 1.2% between 2005 and 2009 and hence reach a total of 49.8 billion barrels in 2009.

16. Porters Five force Model Threat of New Entrants (Low): The oil drilling industry is highly capital extensive. The cost of equipment is high and the skilled labor is also very expensive. Due to high capital and very specific technical knowhow that is required in this industry. It makes the threat of new entrants very low. Power of Suppliers (Medium): The rig builders have more bargaining power is directly dependant on the demand for oil. If the demand for oil and hence the rigs is high, it makes the power of suppliers high. If the demand is low than it gives the drillers a better bargaining power. Power of Buyers (High):Buyers set out tenders and the bidder who bids with the lowest wins. The oil industry is going to grow in the future. However, there is going to be an oversupply of rigs as the number of rigs is likely to increase to 811. Around 45% of them are still without contract. This gives the buyers high bargaining power and may drag the day rates down. Threat of Substitutes (Low): There are many alternatives to oil and natural gas including coal, solar, and wind power. Coal is already well established in the market place while other alternative technologies are still far too inefficient to compete over the next decade. Industry Rivalry (High): There are high exit barriers due to the costs of the rigs and the lack of alternative uses for them. Therefore, companies want to stay in the industry, increasing rivalry. Bids to get contracts is very competitive and lowest cost wins the bid.

26. The Fleet Different types of rigs/equipments: High Specification Floaters(Submersibles & Drillships): • Capable of working in water depths of 4000 feet or greater and harsh environment Intermediate Submersibles: • Capable of working in maximum water depths of 4000 feet Jack-ups: • Capable of working in water depths of 20 feet to 350 feet

27. Rig Locations and Revenue Drivers

28. Breakdown of Revenues • Revenue in GOM has decreased due to moratorium on drilling activity in GOM after Macondo • Incident • Diversification strategy is paying off as revenues from international regions have been increasing • Approx 85 % Revenues come from high specification floaters and intermediate submersibles

33. Valuation

34. Other Scenarios Positive: Anticipation of utilization rates in the 80s% with slightly higher day rates On average, revenues are higher by 9% Fair Value Estimate: $91.90 Negative: Oversupply leads to lower utilization rates and lower day rates. On average, revenues are lower by 10% Fair Value Estimate: $61.66

35. Multiples Valuation

36. Recommendation • To place a limit sell order@$80.00. (for 50 shares purchased in Nov 2008 @ $72.96) • Long Term Capital Gain of: $352 (4.82%)
