      &lt;span&gt;&lt;i&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;FCPA Internal
      Investigation&lt;/span&gt;&lt;/i&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p class="MsoNormal"&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Following
      disclosures by other offshore service companies announcing
      internal investigations involving the legality of amounts
      paid to and by customs brokers in connection with temporary
      importation of rigs and vessels into Nigeria, the Audit
      Committee of our Board of Directors and management commenced
      an internal investigation in July 2007. The investigation
      initially focused on our payments to customs brokers relating
      to the temporary importation of ENSCO 100, our only rig that
      recently operated offshore Nigeria.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&lt;span style=
      "mso-spacerun:yes"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;/span&gt; As is customary for
      companies operating offshore Nigeria, we had engaged
      independent customs brokers to process customs clearance of
      routine shipments of equipment, materials and supplies and to
      process the ENSCO 100 temporary importation permits,
      extensions and renewals. One or more of the customs brokers
      that our subsidiary in Nigeria used to obtain the ENSCO 100
      temporary import permits, extensions and renewals also
      provided this service to other offshore service companies
      that have undertaken Foreign Corrupt Practices Act ("FCPA")
      compliance internal investigations.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The principal
      purpose of our investigation was to determine whether any of
      the payments made to or by our customs brokers were
      inappropriate under the anti-bribery provisions of the FCPA
      or whether any violations of the recordkeeping or internal
      accounting control provisions of the FCPA occurred. Our Audit
      Committee engaged a Washington, D.C. law firm with
      significant experience in investigating and advising upon
      FCPA matters to assist in the internal
      investigation.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Following
      notification to the Audit Committee and to KPMG LLP, our
      independent registered public accounting firm, in
      consultation with the Audit Committee's outside legal
      counsel, we voluntarily notified the United States Department
      of Justice and SEC that we had commenced an internal
      investigation. We expressed our intention to cooperate with
      both agencies, comply with their directives and fully
      disclose the results of the investigation. The internal
      investigation process has involved extensive reviews of
      documents and records, as well as production to the
      authorities, and interviews of relevant personnel. In
      addition to the temporary importation of ENSCO 100, the
      investigation has examined our customs clearance of routine
      shipments and immigration activities in
      Nigeria.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Our internal
      investigation has essentially been concluded. A meeting to
      review the results of the investigation with the authorities
      was held on February 24, 2009. We expect to discuss a
      possible negotiated disposition with the authorities during
      the second half of 2009. It currently is anticipated that the
      matter will be concluded within that period.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Although we
      believe the U.S. authorities will take into account our
      voluntary disclosure, our cooperation with the agencies and
      the remediation and compliance enhancement activities that
      are underway, we are unable to predict the ultimate
      disposition of this matter, whether we will be charged with
      violation of the anti-bribery, recordkeeping or internal
      accounting control provisions of the FCPA or whether the
      scope of the investigation will be extended to other issues
      in Nigeria or to other countries. We also are unable to
      predict what potential corrective measures, fines, sanctions
      or other remedies, if any, the agencies may seek against us
      or any of our employees.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In November 2008,
      our Board of Directors approved enhanced FCPA compliance
      recommendations issued by the Audit Committee's outside
      counsel, and the Company embarked upon an enhanced compliance
      initiative that included appointment of a Chief Compliance
      Officer and a Director - Corporate Compliance. We have
      engaged consultants to assist us in implementing the
      compliance recommendations approved by our Board of
      Directors, which will include an enhanced compliance policy,
      increased training and testing, prescribed contractual
      provisions for our service providers that interface with
      foreign government officials, due diligence for the selection
      of such service providers and an increased Company-wide
      awareness initiative that includes periodic issuance of FCPA
      Alerts.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p class="MsoNormal"&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Since ENSCO 100
      completed its contract commitment and departed Nigeria in
      August 2007, this matter is not expected to have a material
      effect on or disrupt our current operations. As noted above,
      we are unable to predict the outcome of this matter or
      estimate the extent to which we may be exposed to any
      resulting potential liability, sanctions or significant
      additional expense.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;i&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;ENSCO 74
      Loss&lt;/span&gt;&lt;/i&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In September
      2008, ENSCO 74 was lost as a result of Hurricane Ike and was
      presumed to have sunk in the Gulf of Mexico, however,
      portions of its legs remained underwater adjacent to the
      customer's platform. Thereafter, we conducted extensive
      aerial and sonar reconnaissance but failed to locate the rig
      hull. The rig was a total loss, as defined under the terms of
      our insurance policies.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In March 2009,
      the sunken rig hull of ENSCO 74 was located on the seabed
      approximately 95 miles from the original drilling location
      when it was reportedly struck by an oil tanker. Following
      discovery of the sunken rig hull, we removed the hydrocarbons
      remaining onboard and began planning for removal of the
      wreckage. As an interim measure, the wreckage has been
      appropriately marked, and the U.S. Coast Guard has issued a
      Notice to Mariners.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Physical damage
      to our rigs caused by a hurricane, the associated "sue and
      labor" costs to mitigate the insured loss and removal,
      salvage and recovery costs are all covered by our property
      insurance policies subject to a $50.0 million per occurrence
      retention (deductible). The insured value of ENSCO 74 was
      $100.0 million, and we have received the net $50.0 million
      due for loss of the rig.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Coverage for
      ENSCO 74 sue and labor costs and wreckage and debris removal
      costs under our property insurance policies is limited to
      $25.0 million and $50.0 million, respectively. Supplemental
      wreckage and debris removal coverage is provided under our
      liability insurance policies, subject to an annual aggregate
      limit of $500.0 million. We also have a customer contractual
      indemnification that provides for reimbursement of any ENSCO
      74 wreckage and debris removal costs that are not recovered
      under our insurance policies.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;We believe it is
      probable that we will be required to remove the leg sections
      of ENSCO 74 remaining adjacent to the customer's platform
      because they may interfere with the customer's future
      operations. We also believe it is probable that we will be
      required to remove the ENSCO 74 rig hull and related debris
      from the seabed due to the navigational risk it imposes. We
      estimate the leg removal costs could range from $16.0 million
      to $30.0 million, and the hull and related debris removal
      costs could range from $30.0 million to $55.0 million. A
      $16.0 million liability, representing the low end of the
      range of estimated leg removal costs, and a corresponding
      receivable for recovery of those costs, was recorded as of
      June 30, 2009. A $30.0 million liability, representing the
      low end of the range of estimated hull and related debris
      removal costs, and a corresponding receivable for recovery of
      those costs, was recorded as of June 30, 2009. The aggregate
      $46.0 million liability and receivable for the leg and hull
      and related debris removal costs were included in accrued
      liabilities and other and other assets, net, on our June 30,
      2009 condensed consolidated balance sheet.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;On March 17,
      2009, we received notice from counsel representing certain
      underwriters in a subrogation claim alleging that ENSCO 74
      caused a pipeline to rupture during Hurricane Ike. The letter
      requests that we retain all documents/records concerning the
      ENSCO 74 loss and permit the underwriters' representatives to
      attend the salvage operations and participate in a joint
      survey of the rig. The underwriters' counsel has advised that
      the subrogated claim is in the amount of $22.0 million to
      $25.0 million and indicated that the letter was submitted due
      to the proximity (approximately 2 miles) of the pipeline to
      the sunken ENSCO 74 hull and the assumed path of the rig. An
      investigation of the matter is in process. Based on
      information currently available, we have not concluded that
      it is probable that a liability exists with respect to this
      matter.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;On March 18,
      2009, the owner of the oil tanker that struck the hull of
      ENSCO 74 commenced civil litigation against us seeking
      monetary damages in the aggregate amount of $10.0 million for
      losses incurred. Based on information currently available,
      primarily the adequacy of available defenses, we have not
      concluded that it is probable a liability exists with respect
      to the claim of the tanker owner.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p class="MsoNormal"&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;On June 9, 2009,
      we received notice from legal counsel representing another
      pipeline owner which reportedly sustained damages to a subsea
      pipeline. The letter asserts these unquantified damages may
      have been caused by ENSCO 74 during Hurricane Ike. We
      presently are unable to determine whether the pipeline
      damages were caused by ENSCO 74 or the extent of the cost and
      losses associated with the damage. Based on information
      currently available, we have not concluded that it is
      probable that a liability exists with respect to this
      matter.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&lt;span style=
      "mso-spacerun:yes"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;/span&gt; We have liability insurance
      policies that provide coverage for third-party claims such as
      the tanker and pipeline claims, subject to a $10.0 million
      per occurrence self-insured retention (in the event of
      multiple occurrences the self-insured retention is $15.0
      million for two occurrences and $1.0 million for each
      occurrence thereafter) and an annual aggregate limit of
      $500.0 million. Although we do not expect the final
      disposition of the claims associated with the ENSCO 74 loss
      to have a material adverse effect upon our financial
      position, operating results or cash flows, there can be no
      assurances as to the ultimate outcome.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;i&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;ENSCO 29 Wreck
      Removal&lt;/span&gt;&lt;/i&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;A portion of the
      ENSCO 29 platform drilling rig was lost over the side of a
      customer's platform as a result of Hurricane Katrina during
      2005. Although beneficial ownership of ENSCO 29 was
      transferred to our insurance underwriters when the rig was
      determined to be a total loss, management believes we may be
      legally required to remove ENSCO 29 wreckage and debris from
      the seabed and currently estimates that the removal cost
      could range from $5.0 million to $15.0 million. Our property
      insurance policies include coverage for ENSCO 29 wreckage and
      debris removal costs up to $3.8 million. We also have
      liability insurance policies that provide specified coverage
      for wreckage and debris removal costs in excess of the $3.8
      million coverage provided under our property insurance
      policies.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Our liability
      insurance underwriters have issued letters reserving rights
      and effectively denying coverage by questioning the
      applicability of coverage for the potential ENSCO 29 wreckage
      and debris removal costs. In August 2007, we commenced
      litigation against certain underwriters alleging breach of
      contract, wrongful denial, bad faith and other claims which
      seek a declaration that removal of wreckage and debris is
      covered under our liability insurance, monetary damages,
      attorneys' fees and other remedies. The litigation is in an
      early stage and is currently pending a decision from the
      United States Court of Appeals.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;While we
      anticipate that any ENSCO 29 wreckage and debris removal
      costs incurred will be largely or fully covered by insurance,
      a $1.2 million provision, representing the portion of the
      $5.0 million low end of the range of estimated removal cost
      we believe is subject to liability insurance coverage, was
      recognized during 2006.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;i&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Asbestos
      Litigation&lt;/span&gt;&lt;/i&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In August 2004,
      we and certain current and former subsidiaries were named as
      defendants, along with numerous other third-party companies
      as co-defendants, in three multi-party lawsuits filed in the
      Circuit Courts of Jones County (Second Judicial District) and
      Jasper County (First Judicial District), Mississippi. The
      lawsuits sought an unspecified amount of monetary damages on
      behalf of individuals alleging personal injury or death,
      primarily under the Jones Act, purportedly resulting from
      exposure to asbestos on drilling rigs and associated
      facilities during the period 1965 through 1986.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In compliance
      with the Mississippi Rules of Civil Procedure, the individual
      claimants in the original multi-party lawsuits whose claims
      were not dismissed were ordered to file either new or amended
      single plaintiff complaints naming the specific defendant(s)
      against whom they intended to pursue claims. As a result, out
      of more than 600 initial multi-party claims, we have been
      named as a defendant by 65 individual plaintiffs. Of these
      claims, 62 claims or lawsuits are pending in Mississippi
      state courts and three are pending in the U.S. District Court
      as a result of their removal from state court.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p class="MsoNormal"&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Mississippi
      state court cases are under an informal stay of discovery
      issued by a Special Master presiding over these matters while
      discovery is conducted for a designated group of plaintiffs,
      several of which involve us. To date, written discovery and
      plaintiff depositions have taken place in seven cases pending
      against us. No further activity will occur in these cases
      until they are selected for trial. Currently, none of the
      cases pending against us in Mississippi have been set for
      trial. Plaintiffs and defendants have until August 15, 2009
      to select plaintiffs to fill five trial settings during
      2010.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&lt;span style=
      "mso-spacerun:yes"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;/span&gt; The three cases pending in
      federal court were consolidated with 441 other lawsuits filed
      by a Houston law firm. These cases were referred to a
      Magistrate Judge, who ordered parties to conduct general
      discovery in these matters. Discovery specific to each
      plaintiff will take place at a later designated time, if
      deemed necessary by the parties and the court.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;We intend to
      vigorously defend against these claims and have filed
      responsive pleadings preserving all defenses and challenges
      to jurisdiction and venue. However, discovery is still
      ongoing and, therefore, available information regarding the
      nature of all pending claims is limited. At present, we
      cannot reasonably determine how many of the claimants may
      have valid claims under the Jones Act or estimate a range of
      potential liability exposure, if any.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In addition to
      the pending cases in Mississippi, we have eight other
      asbestos or lung injury claims pending against us in
      litigation in various other jurisdictions. Although we do not
      expect the final disposition of the Mississippi and other
      asbestos lawsuits to have a material adverse effect upon our
      financial position, operating results or cash flows, there
      can be no assurances as to the ultimate outcome of the
      lawsuits.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;i&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Working Time
      Directive&lt;/span&gt;&lt;/i&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Legislation known
      as the U.K. Working Time Directive ("WTD") was introduced in
      August 2003 and may be applicable to our employees and
      employees of other drilling contractors that work offshore in
      United Kingdom ("U.K.") territorial waters or in the U.K.
      sector of the North Sea. Certain trade unions representing
      offshore employees have claimed that drilling contractors are
      not in compliance with the WTD in respect of paid time off
      (vacation time) for employees working offshore on a
      rotational basis (generally equal time working and
      off).&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;A Labor Tribunal
      in Aberdeen, Scotland, rendered decisions in claims involving
      other offshore drilling contractors and offshore service
      companies on February 21, 2008. The Tribunal decisions
      effectively held that employers of offshore workers in the
      U.K. sector employed on an equal time on/time off rotation
      are obligated to accord such rotating personnel two-weeks
      annual paid time off from their scheduled offshore work
      assignment period. Both sides of the matter, employee and
      employer groups, appealed the Tribunal decision. The appeals
      were heard by the Employment Appeal Tribunal ("EAT") in
      December 2008.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In an opinion
      rendered on March 9, 2009, the EAT determined that the time
      off work enjoyed by U.K. offshore oil and gas workers,
      typically 26 weeks per year, meets the amount of annual leave
      employers must provide to employees under the WTD. The
      employer group was successful in all arguments on appeal, as
      the EAT determined that the statutory entitlement to annual
      leave under the WTD can be discharged through normal field
      break arrangements for offshore workers. As a consequence of
      the EAT decision, an equal on/off time offshore rotation has
      been deemed to be fully compliant with the WTD.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The employee
      group (led by a trade union) was granted leave to appeal to
      the highest civil court in Scotland (the Court of Session).
      The trade unions initially submitted an application for a
      direct reference to the European Court of Justice, which
      recently was withdrawn. It is expected that a Court of
      Session ruling on the appeal will not be made for several
      years.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;We also received
      inquiries from and responded to the Danish and Dutch
      authorities regarding applicability of the WTD as adopted by
      Denmark and The Netherlands to employees on our rigs
      operating in the Danish and Dutch sectors of the North
      Sea.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Based on
      information currently available, we do not expect the
      ultimate resolution of these matters to have a material
      adverse effect on our financial position, operating results
      or cash flows.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p&gt;
      &lt;span&gt;&lt;i&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Other
      Matters&lt;/span&gt;&lt;/i&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p class="MsoNormal"&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In connection
      with an audit of employee payroll-related returns of an
      international subsidiary, the local taxing authority issued a
      letter to us during the second quarter of 2009 communicating
      its position related to the applicability of certain tax
      exemptions provided by various tax treaties to non-resident
      employees of the subsidiary. We believe that the local taxing
      authority's position is inconsistent with established and
      current tax law in the jurisdiction. We estimate our exposure
      associated with this matter to be approximately $5.5 million,
      but sufficient evidence exists to enable us to conclude that
      our defenses are adequate and a liability is not
      probable.&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;
    &lt;p class="MsoNormal"&gt;
      &lt;span&gt;&lt;span style="font-size:10.0pt"&gt;&amp;#160;&lt;/span&gt;&lt;/span&gt;
    &lt;/p&gt;&lt;span&gt;&lt;span style=
    "font-size:10.0pt;font-family:Times New Roman,serif;mso-fareast-font-family: Times New Roman;mso-fareast-theme-font:minor-fareast;mso-ansi-language:EN-US; mso-fareast-language:EN-US;mso-bidi-language:AR-SA"&gt;&lt;span style="mso-spacerun:yes"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;/span&gt;
    In addition to the foregoing, we are named defendants in
    certain other lawsuits, claims or proceedings incidental to our
    business and are involved from time to time as parties to
    governmental investigations or proceedings, including matters
    related to taxation, arising in the ordinary course of
    business. Although the outcome of such lawsuits or other
    proceedings cannot be predicted with certainty and the amount
    of any liability that could arise with respect to such lawsuits
    or other proceedings cannot be predicted accurately, management
    does not expect these matters to have a material adverse effect
    on our financial position, operating results or cash
    flows.&lt;/span&gt;&lt;/span&gt;
