This document provides an overview and summary of Atwood Oceanics for investors attending the 20th Annual Oil & Offshore Conference. It summarizes Atwood's strategy of modernizing and expanding its fleet through newbuild rig deliveries from 2011-2015. This will provide a younger fleet of ultra-deepwater floaters and high-spec jackups. The summary also outlines Atwood's strong safety and operating performance, revenue efficiency, and focus on superior shareholder returns. Key details include $3.9 billion in contracted backlog through 2016 and funding for remaining capital expenditures of $1.4 billion through operating cash flows and credit facilities.

Statements contained in this report with respect to the future are forward-looking
statements. These statements reflect management’s reasonable judgment with respect
to future events. Forward-looking statements are subject to numerous risks,
uncertainties and assumptions and actual results could differ materially from those
anticipated as a result of various factors including: uncertainties related to the level of
activity in offshore oil and gas exploration and development; oil and gas prices;
competition and market conditions in the contract drilling industry; the risks inherent in
the construction of a rig; delays in the commencement of operations of a rig following
delivery; our ability to enter into and the terms of future contracts; possible cancelation or
suspension of drilling contracts; the availability of qualified personnel; labor relations;
operating hazards and risks; terrorism and political and other uncertainties inherent in
foreign operations (including risks of war, civil disturbances, seizure or damage to
equipment, and exchange and currency fluctuations); the impact of governmental and
industry laws and regulations; and environmental matters. These factors and others are
described and discussed in our most recently filed annual report on Form 10-K, in our

Accelerating High Spec Jack-Up Dayrate Outlook
Bifurcation driving increased utilization and day rates
Jack-up tenders up significantly over the past 6 months
 Driven by demand in the Middle East, SE Asia, Mexico, North Sea and India
Market outlook for 2013 remains favorable
 Overall contracted utilization rates for high spec rigs approximately 100%
 Dayrates currently in the $165,000 to $195,000 range, depending on the
geographic region and contract term
67 high specification rigs under construction
 17 contracted
 50 to be delivered over next 40 months
Many older rigs are not likely to return to market
 27 jack-up rigs permanently removed from the fleet in 2011 and 2012;
compared to aggregate of 18 rigs for the previous 15 years ending 2010
Jack-up demand continues to shift toward newer, high-specification rigs
