Fleet Status Highlights New Contracts and Significant Rate Increases ENSCO DS-7, a newbuild ultra-deepwater drillship scheduled for delivery in third quarter 2013, has been contracted by TOTAL in Angola at an average rate of approximately $648,000 per day over its three-year contract. ENSCO 107 has been contracted to OMV in New Zealand beginning October 2013, after its existing contracts are completed. The day rate in the $230,000 range is one of the highest for its rig class since 2007. ENSCO 8501, currently working for Nexen/Noble Energy in the U.S. Gulf of Mexico, received a one-year contract extension from Noble Energy commencing August 2013 at a rate of approximately $525,000 per day. ENSCO 5006, currently working for Noble Energy in Israel, increased its day rate by more than $140,000 to approximately $430,000 per day. Once its current contract is completed, ENSCO 5006 will mobilize to Singapore for shipyard upgrades before it mobilizes to Australia for a 40-month contract with Inpex at an average day rate of approximately $490,000 over the contract term. ENSCO 8500 had its one-year priced option exercised by Anadarko/Eni commencing September 2013 in the U.S. Gulf of Mexico. ENSCO 81 has been contracted to Stone in the U.S. Gulf of Mexico beginning in April 2013 for at least six months at approximately $138,000 per day, increasing its day rate by more than $45,000 per day. Contract Commencements ENSCO DS-6, a newbuild ultra-deepwater drillship, is on location for BP in Angola and has commenced its five-year contract. ENSCO 8506, a newbuild ultra-deepwater semisubmersible, is on location and has commenced work for Anadarko in the U.S. Gulf of Mexico. Operations Update This Fleet Status Report reflects zero rate downtime related to GE Oil & Gas connector bolts (see Ensco press release issued 7 February 2013).

Definitions and Disclaimers

Day Rate Definition. The day rates reflected in this Fleet Status Report are the operating day rates charged to customers, which may include estimated contractual adjustments for changes in operating costs and/or reimbursable cost adjustments for ongoing expenses such as crew, catering, insurance and taxes. The day rates, however, do not include certain types of non-recurring revenues such as lump sum mobilization payments, revenues earned during mobilizations, revenues associated with contract preparation and other non-recurring reimbursable items such as mobilizations and capital enhancements, and the impact of the fair market value adjustments to previously acquired drilling contracts.  Routine and non-routine downtime may reduce the actual revenues recognized during the contract term.  Additionally, the Company occasionally negotiates special rates with customers as noted in the comments that reduce revenues recognized during the contract term.

Forward Looking Statement. Statements contained in this Fleet Status Report that are not historical facts are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements include words or phrases such as “anticipate,” “believe,” “estimate,” “expect,” “intend,” “plan,” “project,” “could,” “may,” “might,” “should,” “will” and similar words and specifically include statements involving future rig day rates; cost adjustments; utilization; estimated rig availability; contract duration, status, terms and other contract commitments; customers; rig enhancement projects; new rig commitments; the expected period of time and number of rigs that will be in a shipyard for repairs, maintenance, enhancement or construction; and scheduled delivery dates for new rigs. Such statements are subject to numerous risks, uncertainties and assumptions that may cause actual results to vary materially from those indicated, including governmental regulatory, legislative and permitting requirements affecting drilling operations; changes in worldwide rig supply and demand, competition and technology; future levels of offshore drilling activity; downtime and other risks associated with offshore rig operations, relocations, severe weather or hurricanes; possible cancellation or suspension of drilling contracts as a result of mechanical difficulties, performance or other reasons; risks inherent to shipyard rig construction, repair, maintenance or enhancement; actual contract commencement dates; environmental or other liabilities, risks or losses; our ability to attract and retain skilled personnel on commercially reasonable terms; governmental action, civil unrest and political and economic uncertainties; terrorism, piracy and military action; and the outcome of litigation, legal proceedings, investigations or other claims or contract disputes.  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 Results of Operations” in Part II of our most recent annual report on Form 10-K, as updated in our subsequent quarterly reports on Form 10-Q, which are available on the SEC’s website at www.sec.gov or on the Investor Relations section of our website at www.enscoplc.com.  Each forward-looking statement speaks only as of the date of the particular statement, and we undertake no obligation to publicly update or revise any forward looking statements, except as required by law.
