2









 







December 23, 2009 (or, if different, the effective date of the Merger) with respect to the
amendment to Section 7.2 of the amended and restated Original SERP; and



     WHEREAS, the Company now desires to adopt this Amendment No. 4 to the amended and restated
Original SERP in order to (i) affirmatively provide that (A) the Company does not intend for, and
shall not consider, the Reorganization to constitute a “Change-in-Control” of the Company under
Section 10.2 of the amended and restated Original SERP, and (B) the amended and restated Original
SERP shall continue notwithstanding the Reorganization as if the Reorganization does not constitute
a Change-in-Control of the Company, (ii) specifically provide that (A) each share of common stock
of the Company held by the Company stock fund on the effective date of the Merger will be converted
into one Ensco ADS pursuant to the Merger Agreement, and (B) the references to “Company stock fund”
in Section 7.2 of the amended and restated Original SERP shall thereafter be read and considered to
be references to the “Ensco ADS fund,” and (iii) make such other conforming changes to the amended
and restated Original SERP as determined necessary;



     NOW, THEREFORE, in consideration of the premises and the covenants herein contained, the
Company hereby adopts the following Amendment No. 4 to the amended and restated Original SERP:



1. The final two sentences of the second paragraph of Section 10.2 of the Original SERP are hereby
amended to read as follows following the effective date of the Merger:



     For purposes of the Plan, a Change-in-Control of the Company shall be deemed to occur if (1)
any person or group within the meaning of the Securities Exchange Act of 1934, as amended, acquired
beneficially (together with voting securities of Ensco UK beneficially held by such person or
group) more than 50% of the outstanding voting securities of Ensco UK (whether directly,
indirectly, beneficially or of record) pursuant to any transaction or combination of transactions,
or (2) the individuals who, on January 1, 2004, constituted the Board (the “Incumbent Board”)
cease, for any reason, to constitute at least a majority thereof. For purposes of this provision, a
person becoming a member of the Board subsequent to January 1, 2004 whose election or nomination
for election by the Company’s stockholders was approved by a vote of at least a majority of the
members of the Board comprising the Incumbent Board shall for this purpose be considered as though
he or she was a member of the Incumbent Board.



     2. A new third paragraph is hereby added to Section 10.2 of the amended and restated Original
SERP, effective on the date of execution of this Amendment No. 4 by the Company, to read as
follows:



     Notwithstanding the foregoing and pursuant to the power and authority vested in the Board
under the Plan, the Board hereby determines that a “Change-in-Control” of the Company shall not be
deemed to have occurred for purposes of the Plan by virtue of the consummation of any transaction
or series of related transactions immediately following which the beneficial holders of the voting
stock of the Company immediately before such transaction or series of transactions continue to have
a majority of the



3









 







direct or indirect ownership in one or more entities which, singly or together, immediately
following such transaction or series of transactions, either (i) own all or substantially all of
the assets of the Company as constituted immediately prior to such transaction or series of
transactions, or (ii) are the ultimate parent with direct or indirect ownership of all of the
voting shares of the Company after such transaction or series of transactions. The stockholders of
the Company approved and adopted at the Special Meeting of Stockholders on December 22, 2009 the
Agreement and Plan of Merger and Reorganization (the “Merger Agreement”), by and between the
Company and ENSCO Newcastle LLC, a newly formed Delaware limited liability company (“Ensco
Mergeco”) and a wholly-owned subsidiary of ENSCO Global Limited, a newly formed Cayman Islands
exempted company (“Ensco Cayman”) and a wholly-owned subsidiary of the Company, pursuant to which
Ensco Mergeco merged (the “Merger”) with and into the Company, with the Company surviving the
Merger as a wholly-owned subsidiary of Ensco Cayman (the “Reorganization”). Specifically, (i) the
Reorganization shall not constitute a Change-in-Control of the Company, and (ii) the Plan, as
amended, shall continue notwithstanding the Reorganization as if the Reorganization does not
constitute a Change-in-Control of the Company. Following the effective date of the Merger, the
references to “stock of the Company” and “shares of the Company” in the third paragraph of this
Section 10.2 shall be changed to “securities of Ensco UK.”



     3. A new sixth paragraph is hereby added to Section 7.2 of the amended and restated Original
SERP to read as follows:



     Ensco Cayman (as defined in Section 10.2) became, in connection with the Merger (as defined in
Section 10.2), a wholly-owned subsidiary of ENSCO International Limited, a newly formed private
limited company incorporated under English law which, prior to the effective time of the Merger,
re-registered as a public limited company named “Ensco International plc” (“Ensco UK”). Pursuant
to the Merger Agreement, each issued and outstanding share of Company common stock, including each
share of Company common stock held by the Company stock fund, on the effective date of the Merger
will be converted into one Ensco ADS and, thereafter, the references to “Company stock fund” in
this Section 7.2 shall be read and considered to be references to the “Ensco ADS fund.” For this
purpose, “Ensco ADS” means an American depository share, evidenced by an American depository
receipt which represents a Class A ordinary share in Ensco UK.



     IN WITNESS WHEREOF, the Company, acting by and through its duly authorized officers, has
caused this Amendment No. 4 to the amendment and restatement of the Original SERP to be executed on
the date first above written.
