regular meeting held on March 10, 2008;</FONT></P>

<P><FONT SIZE="-1">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS,
the Board, upon recommendation of the Committee, approved this amendment and restatement of the 2005
SERP during a regular meeting held on November 4, 2008; and</FONT></P>

<P><FONT SIZE="-1">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;WHEREAS,
the Company now desires to amend and restate the 2005 SERP, effective as of January 1, 2005, except as
specifically provided otherwise to the contrary herein, in order to (i) facilitate compliance with the final
Treasury regulations under section 409A of the Code, and (ii) incorporate the amendments to the 2005 SERP
previously made by Amendment No. 1 and Amendment No. 2;</FONT></P>

<P><FONT SIZE="-1">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;NOW, THEREFORE,
in consideration of the premises and the covenants herein contained, the Company hereby adopts
the following amended and restated 2005 SERP:</FONT></P>

<P ALIGN="CENTER"><FONT SIZE="-1"><B>ARTICLE I<BR><BR>PURPOSE</B></FONT></P>

<P><FONT SIZE="-1">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
objective and purpose of this Plan is to attract and retain competent officers, key executives, management
and highly compensated employees by offering flexible compensation opportunities to officers, key executives,
management and highly compensated employees of the Company and its Affiliates and to offer them an opportunity to
build an estate or supplement income for use after retirement.  In addition to this Plan, the Company sponsors
certain broad-based employee benefit plans covering its employees.</FONT></P>

<P><FONT SIZE="-1">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Through this Plan,
the Company intends to permit the deferral of compensation and to provide additional benefits
to a select group of management or highly compensated employees of the Company and its Affiliates.  Accordingly,
it is intended that this Plan shall not constitute a "qualified plan" subject to the limitations of section
401(a) of the Code, nor shall it constitute a "funded plan" for purposes of such requirements.  It is also
intended that this Plan shall be exempt from the participation and vesting requirements of Part 2 of Title I of
ERISA, the funding requirements of Part 3 of Title I of ERISA, and the fiduciary requirements of Part 4 of Title
I of ERISA by reason of the exclusions afforded plans which are unfunded and maintained by an employer primarily
for the purpose of providing deferred compensation for a select group of management or highly compensated
employees.</FONT></P>

aggregated with any other deferrals made by the Participant under the 401(k) Plan, for any calendar year, shall
not exceed 50 percent of his or her Compensation for the calendar year.  Notwithstanding the preceding provisions

six percent of the Participant's Compensation, reduced by the amount of employer matching contributions, if any,

would have been entitled under the 401(k) Plan for a Plan Year, but were prevented from receiving under the
401(k) Plan because of one or more of the limitations described in Section 4.1(a).  The Employer Discretionary
Contribution, if any, may be made with respect to active Participants and inactive Participants, as determined by
the Committee.  Amounts representing Employer Discretionary Contributions, if any, for a Plan Year shall be

spouse  or a dependent (as defined in section 152 of the Code, without regard to sections 152(b)(1), (b)(2), and
(d)(1)(B) of the Code) of the Participant, (ii) a loss of the Participant's property due to casualty (including
the need to rebuild the Participant's home following damage to the home not otherwise covered by insurance, for
example, not as a result of a natural disaster), or (iii) other similar extraordinary and unforeseeable
circumstances arising as a result of events beyond the control of the Participant.  An unforeseeable emergency
shall not exist, however, if the emergency may be relieved (i) by reimbursement or compensation from insurance or
otherwise, (ii) by liquidation of the Participant's assets, to the extent the liquidation of such assets would
not itself cause a severe financial hardship, or (iii) by cessation of deferrals under this Plan. In addition, an
unforeseeable emergency shall not exist as a result of the Participant's need to send a child to college or
desire to purchase a home.  Whether a Participant is faced with an unforeseeable emergency permitting a
distribution under this Section 5.2(a) is to be determined by the Administrator based on all of the relevant
facts and circumstances of each case in accordance with section 409A of the Code.  The amount distributed to a
Participant on account of an unforeseeable emergency may not exceed the amount reasonably necessary to satisfy
such emergency, plus amounts necessary to pay any Federal, state or local income taxes or penalties reasonably
anticipated as a result of the distribution, after taking into account (i) the extent to which the hardship is or
may be relieved through reimbursement or compensation from insurance or otherwise, or by liquidation of the
Participant's assets, to the extent the liquidation of such assets would not itself cause a severe financial
hardship, and (ii) any additional Compensation that will be available if the Participant's Deferred Compensation
Election is cancelled under this Section 5.2(a).  The amount the Administrator determines is eligible for

an applicable Federal, state, local or foreign ethics law or conflicts of interest law (including where such
payment is reasonably necessary to permit the Participant to participate in activities in the normal course of

months.  In addition, the Participant may elect on his or her initial Deferred Compensation/Participation
Agreement filed with the Administrator under this Plan to defer the Benefit payment date or Benefit commencement

the Participant may change the form in which his or her Benefits will be paid as specified in his or her initial

installments over a period of 60 months.  If an election is made pursuant to the preceding sentence, (i) it

election related to a payment that is not made by reason of the Participant's Disability, the occurrence of an
unforeseeable emergency under Section 5.2(a), or the Participant's death, the first payment with respect to which
this election is made shall be deferred for a period of not less than five years from the date on which the

installments, the remaining portion of the Participant's Benefits shall continue to be paid in monthly
installments to his or her Beneficiary for the remaining installment period in the same amount and manner as such
Benefits would have been paid to the Participant.  If the Participant elects to defer the Benefit payment date or
Benefit commencement date and dies before that deferred Benefit payment date or deferred Benefit commencement

with the Administrator.  The Administrator will recognize the most recent written Beneficiary designation on file
prior to a Participant's death.  If a designated Beneficiary is not living at the time of the Participant's
death, then the Administrator shall pay Participant's Benefits to the Participant's personal representative,
executor, or administrator, as specified by the appropriate legal jurisdiction.  Any such payment to the
Participant's Beneficiary or, if applicable, to his or her personal representative, executor or administrator
shall operate as a complete discharge of all obligations of the Administrator and the Employer to the extent of
the payment so made.</FONT></P>

person deemed by the Administrator, in its sole discretion, to have incurred expenses for such person otherwise
entitled to payment, in such manner and proportions as the Administrator may determine.  Any such payment shall
be a complete discharge of the liabilities of the Employer under this Plan, and the Employer shall have no
further obligation to see to the application of any money so paid.</FONT></P>

<P><FONT SIZE="-1">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.1&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>Funding.</B>
All Benefits under this Plan shall be paid or provided directly by the Employer.  Such Benefits shall
be general obligations of the Employer which shall not require the segregation of any funds or property
therefor.  The assets of the Benefit Reserve Trust established in connection with the adoption of the Original
SERP allocable to the amounts credited to the Accounts of Participants as described in Section 2.1(g)(ii)
attributable to participation in the Original SERP shall be considered a means to assist the Employer to meet its
contractual obligations under this Plan with respect to those amounts of Benefits.</FONT></P>

<P><FONT SIZE="-1">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Notwithstanding
the foregoing, in the discretion of the Employer, the Employer's obligations hereunder may be
satisfied from a grantor trust or trusts established by the Employer, the terms of which shall be substantially
similar to the terms of the model trust issued by the Internal Revenue Service in Revenue Procedure 92-64 and
shall comply with the requirements of section 409A of the Code, from an escrow account established at a bank or
trust company, or from an insurance contract or contracts owned by the Employer.  The assets of any such trust,
escrow account and any such insurance policy shall continue for all purposes to be a part of the general funds of
the Employer, shall be considered solely a means to assist the Employer to meet its contractual obligations under
this Plan and shall not create a funded account or security interest for the benefit of any Participant under
this Plan.  All such assets shall be subject to the claims of the general creditors of the Employer in the event
the Employer is Insolvent.</FONT></P>

<P><FONT SIZE="-1">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If a single
trust or other funding vehicle is established as a reserve for the obligations hereunder of more than
one Employer, including by the Company with respect to its obligations to its non-employee directors under the
ENSCO 2005 Non-Employee Director Deferred Compensation Plan, the assets of any such trust or funding vehicle
shall, to the extent attributable to contributions made by a particular Employer, be subject to the claims of the
general creditors of that Employer in the event such Employer is Insolvent, and each Employer shall be treated as
a separate grantor to the extent of its participation in any trust so established.  To the extent that any person
acquires a right to receive a payment from an Employer under this Plan, such right shall be no greater than the
right of any unsecured general creditor of that Employer.</FONT></P>

<P><FONT SIZE="-1">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.2&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>Investments.</B>
If a trust is established as provided for in Section 7.1, earnings and/or losses of the trust
attributable to amounts credited to a Participant's Account shall increase or, if applicable, decrease such
Participant's Account for purposes of determining the Participant's Benefits payable hereunder.  The Committee
may determine from time to time to direct the investment manager appointed pursuant to any such trust to invest
the balance of a Participant's Account in accordance with the wishes and written directions of that Participant
from among the registered mutual funds and the Company stock fund offered to the participants in the 401(k) Plan
(which have been revised effective as of January 1, 2008 and will be further revised effective as of February 1,
2009) from time to time under the terms of the 401(k) Plan.  Separate elections may be made with respect to the
different types of contributions credited to his or her Account.  If the Committee determines for any reason that
a particular registered mutual fund available under the 401(k) Plan cannot be made available under this Plan, a
comparable fund will be substituted in its place.</FONT></P>

Discretionary Contributions, if any, and Matching Contributions, if any, credited to his or her Account on or
before May 31, 2008 may be invested in the Company stock fund.  Effective June 1, 2008, a Participant may not
direct that more than 50 percent of the balance of his or her Account attributable to Deferred Compensation,
Employer Discretionary Contributions, if any, and Matching Contributions, if any, credited to his or her Account
after May 31, 2008 may be invested in the Company stock fund.  If the investment election of any Participant in
effect on June 1, 2008 provides for an election in excess of 50 percent to the Company stock fund, that
investment election shall be automatically revised, effective June 1, 2008, with respect to the specific election
to the Company stock fund to provide for an election of 50 percent to the Company stock fund and the percentage
elected in excess of 50 percent shall be deemed to be an election of that excess percentage to the particular T.
Rowe Price target date retirement fund offered to participants in the 401(k) Plan determined by the age of the
Participant.  Notwithstanding that the balance of a Participant's Account that is invested in the Company stock
fund on June 1, 2008 is 50 percent or more of the total balance of his or her Account on that date, the
Participant's Account may continue to hold that investment interest in the Company stock fund after May 31, 2008
and the investment election in the Company stock fund permitted by the two preceding sentences with respect to
contributions credited to his or her Account after May 31, 2008 shall not be affected.  A Participant shall not
be permitted, however, to direct the investment manager (in writing, or if allowed by the Administrator, by
giving an interactive electronic communication) after May 31, 2008 to change the investment of the then balance
of his or her Account if (i) that investment election requires reinvestment of any portion of his or her Account
into the Company stock fund and the balance of his or her Account that is invested in the Company stock fund on
that date is 50 percent or more of the total balance of his or her Account on that date, or (ii) the effect of
that investment election would result in more than 50 percent of the total balance of his or her Account on that
date being invested in the Company stock fund.</FONT></P>

the Committee has also determined that it will direct the investment manager appointed
pursuant to any such trust to invest up to 100 percent of the balance of a Participant's Account in accordance
with the wishes and written directions of that Participant pursuant to the terms, conditions and limitations of
the agreements governing the T. Rowe Price TradeLink+ self-directed brokerage investment program, as amended from
time to time.</FONT></P>

<P><FONT SIZE="-1">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If a Participant
is permitted to direct the investment manager appointed pursuant to any trust established
pursuant to Section 7.1 to invest the balance of his or her Account and fails to complete and file with the
Administrator using the form furnished by the Administrator or, if allowed by the Administrator, to give an
interactive electronic communication, directing the investment manager concerning the investment of his or her
Account, the entire balance of his or her Account shall be invested in the same manner as the investment
allocation then currently in effect for that Participant's individual account in the 401(k) Plan pending the
Administrator's receipt of investment direction from or an interactive electronic communication by the
Participant, or in such other default investment fund or funds as may be determined by the Administrator from
time to time.</FONT></P>

providing for current or deferred compensation for employees.  Unless specifically provided otherwise in any plan

The Committee shall have the right to amend this Plan at any time and from time to time, including a
retroactive amendment.  Any such amendment shall become effective upon the date stated therein, and shall be
binding on all Employers then participating in this Plan, except as otherwise provided in such amendment;

<P><FONT SIZE="-1">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.2&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<B>Termination.</B>
The Company has established this Plan with the bona fide intention and expectation that from year

reserves the right to terminate this Plan in its entirety at any time; provided, however, that no such action
shall affect any Benefit adversely to which a Participant would be entitled had he or she incurred a separation
from service with his or her Employer and all Affiliates immediately before such termination was effective and
any decision to terminate this Plan shall comply with section 409A of the Code.</FONT></P>

of compensation are treated as having been deferred under a single plan with this Plan under Treas. Reg.
1.409A-1(c)(2) must also be terminated and liquidated and the benefits distributed to the covered participants no
later than the 12-month anniversary of the date the Company and the Employer irrevocably take all necessary
action to terminate and liquidate the aggregated agreements, methods, programs and other arrangements.</FONT></P>

constitutes more than 50 percent of the total fair market value or total voting power of the stock of the

recent acquisition by such person or persons) assets from the Company that have a total gross fair market value
equal to or more than 40 percent of the total gross fair market value of all of the assets of the Company
