Ensco to Acquire Atwood Oceanics 4.Why has this occurred now? Current industry downturn has significantly changed the competitive landscape and the economics of offshore drilling. Offshore drillers with scale, high-specification assets and strong balance sheets are in best position for the market recovery. This acquisition is consistent with these changes. Why Atwood? Atwood has a modern rig fleet and an excellent reputation for safety, operational excellence and client satisfaction. This makes Atwood Oceanics an attractive acquisition target. By successfully completing the acquisition, Ensco expects to: enhance their fleet; maintain their balanced exposure to deep- and shallow-water markets; expand their customer base; and increase their presence in key geographies.

Ensco to Acquire Atwood Oceanics What does this mean for me? The acquisition is still subject to regulatory and shareholder approvals. Expect normal course of business until the closing of the transaction. We expect closing to occur before the end of the calendar year. The majority of offshore crews will not be materially affected. Many headquarters and shore-based positions will be consolidated.   Employment will continue following closing until such time as you are notified of termination. We do not plan to carry out any further layoffs at Atwood between today and closing. 

Ensco to Acquire Atwood Oceanics 7.What can I expect in the way of severance? In the event a current shore-based employee is no longer required, that employee will be eligible for a Change of Control (COC) severance package. A general summary of the COC severance package is to follow, but please note, it is qualified by the terms and conditions of the COC Plan available on myAtwood.   a)Eligibility Most active headquarters and shore-based employees are eligible. An employee must be active as of May 30, 2017. To receive the COC severance package, you also need to continue in employment up until the date you are terminated. Employment must end subject to the result of a “Qualifying Termination” under the COC Plan. There are conditions attached to the term “Qualifying Termination.” It basically means that if you are offered a position with equivalent salary and target bonus amount, and decline the offer, you will not be eligible to receive severance. We do not plan to carry out any further layoffs at Atwood between today and closing.  Anyone terminated “for cause” will not be eligible for the COC severance package.

Ensco to Acquire Atwood Oceanics b)Formula to calculate Severance Amount Calculated at the day of closing 1 week of Protected Pay for every $10,000 of Base Salary (rounded up) PLUS 2 weeks of Protected Pay for every year of service (rounded up) with a minimum of 12 weeks and maximum of 52 weeks. Definition of Protected Pay = (Annual Salary + Target Bonus)/ 52 weeks. Accelerated vesting of 401K. Pay-out of accrued bonus (at target) and accrued and unused vacation.  c)Welfare Benefits General eligibility for eighteen (18) months of COBRA coverage, includes continuation of group health care, vision and dental coverage. Under the COC Plan, the Company will continue your medical, dental and vision coverage at the rate you were paying prior to a Qualifying Termination for the same number of weeks applied to the Severance Amount calculation. Following the expiration of that period, the cost of COBRA coverage will be the obligation of the former employee. The provision of these benefits will be secondary to employer-provided benefits if you are re-employed.  

Ensco to Acquire Atwood Oceanics The COC Plan allows for a minimum of 12 weeks of Protected Pay and maximum of 52 weeks of Protected Pay.  Formula to calculate COC Severance Amount Example:Annual Salary: $58,000 Bonus Target: 12% or $6,960 Years of Service: 4.8 years   Protected Pay calculation: $58,000 + $6,960 = $64,960 / 52 = $1,249.23 weekly pay   Annual Salary (rounded up) $60,000/$10,000 = 6 weeks of Protected Pay; PLUS Years of Service (rounded up) 5 x 2 = 10 weeks of Protected Pay TOTAL:16 Weeks of Protected Pay = 16 x $1,249.23 = $19,988 PLUS:Accrued target bonus (pro rata). PLUS: Payout of any accrued and unused vacation. PLUS:401(k) accounts are vested. Note:The COC plan protects employees for 12 months past the date of closing (i.e., for a Qualifying Termination after closing).

Ensco to Acquire Atwood Oceanics 8.When can I expect to be paid severance? Subject to waiver and release requirements, the COC severance benefit is paid within 60 days following the termination date.   9.What happens between now and closing? Atwood and Ensco will continue operations as separate entities until the acquisition is finalized. You are not to contact employees at Ensco unless specifically authorized by your supervisor.   10.What should I do if I receive questions from customers or vendors?  Managers will be communicating with customers and vendors regarding our announcement. Should you receive questions from other outside parties, such as the media or analysts, please contact our Legal department.  

Ensco to Acquire Atwood Oceanics What happens next? It is very much “Business as Usual” at Atwood Oceanics. We need to continue our focus on safe operations, operational excellence, client satisfaction and adherence to our “Guiding Principles”. Remember, the transaction is still subject to regulatory and shareholder approval (at both Atwood and Ensco). We must maintain our high level of professional standards. We still have a company to run and we need to “Finish Strong”!  We will provide periodic updates on the progress to closing. We intend to set up a schedule for employees to meet with HR and discuss their individual circumstances.
