Such statements are subject to numerousrisks, uncertainties and assumptions that may cause actual results to vary materially from those indicated, includingcommodity price fluctuations, customer demand, new rig supply, downtime and other risks associated with offshore rigoperations, relocations, severe weather or hurricanes; changes in worldwide rig supply and demand, competition andtechnology; future levels of offshore drilling activity; governmental action, civil unrest and political and economicuncertainties; terrorism, piracy and military action; risks inherent to shipyard rig construction, repair, maintenance orenhancement; possible cancellation, suspension or termination of drilling contracts as a result of mechanical difficulties,performance, customer finances, the decline or the perceived risk of a further decline in oil and/or natural gas prices, orother reasons, including terminations for convenience (without cause); the outcome of litigation, legal proceedings,investigations or other claims or contract disputes; governmental regulatory, legislative and permitting requirementsaffecting drilling operations; our ability to attract and retain skilled personnel on commercially reasonable terms;environmental or other liabilities, risks or losses; debt restrictions that may limit our liquidity and flexibility; our ability torealize the expected benefits from our redomestication and actual contract commencement dates; cybersecurity risksand threats; and the occurrence or threat of epidemic or pandemic diseases or any governmental response to suchoccurrence or threat. In addition to the numerous factors described above, you should also carefully read and consider“Item 1A. Risk Factors” in Part I and “Item 7. Management’s Discussion and Analysis of Financial Condition and Resultsof Operations” in Part II of our most recent annual report on Form 10-K, as updated in our subsequent quarterly reportson Form 10-Q, which are available on the SEC’s website at www.sec.gov or on the Investor Relations section of ourwebsite at www.enscoplc.com.

Key Points to Remember
1. Deepwater production is 8% of global supply
2. Offshore reserves are a critical part of major E&P portfolios
3. Excessive costs/inefficiencies crept into sector during the $100+ oilenvironment
4. Industry is proactively responding to commodity price pressures
5. Breakeven commodity prices for offshore programs are declining
6. Unprecedented decline in E&P spending will lead to supply sidechallenges – the longer the duration of the pullback, the greater thechance of significant upward movements in commodity prices
Outlook for Offshore E&P
26
• Shell has stated that deepwater is a key driver of growth– “Integrated gas and deepwater, which have been growth
priorities for Shell in recent years and will reach significantscale with BG's positions included, really accelerating the deliveryof the growth we had targeted there.” - Feb. 2016
• Shell’s acquisition of BG aligns with the company’spriorities in deepwater, particularly in Brazil– “Brazil is an absolutely outstanding upstream province … and at
this moment is the most exciting part of the industry.” - Apr. 2015
– “The potential is absolutely gigantic – there is much more tocome.” - Apr. 2015
Importance of Deepwater
27
Other major E&Ps have made similar comments regarding theimportance of deepwater projects to future growth
– BP: “We don't think that the deepwater is played out … there's a widespectrum of quality in any resource category across the industry … it's notabout water depth; it's about the quality of our reservoirs. And we holdsome very strong deepwater investments going forward.” - Oct. 2015
– Chevron: “Major capital projects will still be required to sustain productionand renew the base … these projects offer diversity in location and assetclass including conventional, LNG, deepwater and heavy oil each of whichare expected to present profitable opportunities in the future.” - Mar. 2016
– Total: “A new direction is being taken to carry out deep offshoreoperations in even deeper waters … and at greater distances for multi-phase production transport … which is fully in line with the ambitious goalsof [the company’s] exploration and production [business] and supportsmajor technology-intensive assets such as Libra in Brazil.” - Apr. 2015
Importance of Deepwater
28
• BP Mad Dog: Phase 2
– Cost estimates reduced to less than $10 billion from previousestimate of $22 billion
– Project re-engineering through standardization and scopeoptimization, coupled with industry deflation, resulted in significantly lesscapital required to develop approximately 90% of resources
• Shell Appomattox
– 20% reduction in project costs from supply chain savings, designimprovements, etc.
• Total Block 32
– Capital expenditure estimate reduced by $4 billion to $16 billion
– Optimized project design and contracting strategy
• Statoil
– “Standardization is the new innovation.”
Customers Re-Engineering Projects
29
Recent strategic combinations/alliances among servicecompanies to drive greater efficiencies and lower the breakevencommodity prices for projects:
• Schlumberger/Cameron – strategic innovation, efficiencies and costreductions in deepwater projects; driving down breakeven commodity pricelevels
• GE Oil & Gas/McDermott – improve design/planning of offshore oil and gasfield developments
• OneSubsea/Subsea 7 – enhance project delivery, improve recovery andoptimize the cost and efficiency of deepwater subsea developments
• FMC Technologies/Technip – overhaul subsea field operations to driveefficiencies
• Baker Hughes/Aker Solutions – develop technology for production solutionsthat will boost output, increase recovery rates and reduce costs for subseafields
• Schlumberger/OneSubsea/Helix – optimize the cost and efficiency of subseawell intervention systems
Service Sector Response
30
• Shallow water well programs have lower breakeven commodityprice points on average than deepwater projects
– less complex drilling requirements, shallower water depths and greateraccess to existing infrastructure
• More diverse customer base; shallow water demand a functionof customer- and region-specific factors
– increased rig demand in the Middle East from NOCs
– leases requiring continued drilling in areas like North Sea and WestAfrica have stabilized demand as exploration capex has been reduced
– well intervention now more economic in lower day rate environment
– U.S. Gulf of Mexico and Asia Pacific markets are challenged due tocapex reductions and uncontracted newbuild supply, respectively
• Drillers with established operational and safety track records havean advantage in contracting rigs
– zero newbuilds being built in China by speculators have been contracted
Jackup Market Dynamics
31
• We have taken proactive capitalmanagement, fleet restructuring andexpense management decisions
• We believe our liquidity and balancesheet position gives us options
• We have invested in innovation andengineering to grow our leadershipposition for the future
• The offshore drilling industry will bereconfigured by this downturn – newerentrants and companies with weakerbalance sheets will struggle
Summary
In a very challengedmarket we believeour liquidity and
balance sheetprovide options
