SUBJECT:		Functional Integration Leaders First Weekly Meeting Held

The Integration Leadership Team (ILT) conducted the first weekly update meeting of the Functional Integration Leaders (FILs) yesterday. Following the kick-off meeting in Houston last week, the FILs were tasked with completing their charters that lay out key objectives, and developing detailed plans to ensure a smooth transition on Day One and beyond. Given our ability to now share more information between Ensco and Pride to facilitate the integration, significant progress is clearly being made that will bring our two companies together as one when the transaction closes. The closing may occur as early as this quarter, subject to final shareholder approvals and the terms of the merger agreement.

Each of the 17 functional groups reported significant accomplishments over the last week, provided a look ahead for planned activities in the upcoming week, and discussed new issues or decisions that need to be addressed. A few of the key accomplishments discussed by the FILs included:

	•		Our Marketing groups are beginning to work some bids and tenders jointly on appropriate projects outside of the U.S. and with the knowledge and concurrence of the customer. (Marketing)
	•		A gap analysis of Ensco’s and Pride’s Safety Management Systems has been initiated. (SHE)
	•		Consolidated cash forecasting process is underway. (Treasury)
	•		Codes of Business Conduct from each company are being combined. (Compliance)
	•		A relocation vendor to accommodate Dallas to Houston moves was selected. (HR)
	•		A review of both company’s HR policies was undertaken and work is being done to consolidate them. (HR)
	•		E-Room was set up for information sharing among team members. (Enterprise Applications)

	•		It was determined that Technical Training will report into HR in the new company. (Technical Training)
	•		A comprehensive project plan was drafted to achieve effective Day One communications that will include a new corporate video, integrated website, marketing brochure, investor presentation, etc. (Investor Relations/Corporate Communications/Branding)
	•		A gap analysis of Ensco’s and Pride’s websites has been completed. (Investor Relations/Corporate Communications/Branding)

The ILT also took the opportunity to report that work is continuing on a number of fronts and that some of their priorities include finalizing the management team for the new company, and determining the structure for the business units. Announcements on some of these should be forthcoming in the near term.

The ILT and FILs are looking ahead to next week’s meeting that will serve as a report to the Executive Management Committee on initial observations and 100 Day Priorities of all of the groups, and we will provide an update following that meeting.
