    &lt;/div&gt;
    &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;Noble Asset Company Limited (&amp;#8220;NACL&amp;#8221;), our wholly-owned, indirect subsidiary, was named one of
    21 parties served a Show Cause Notice (&amp;#8220;SCN&amp;#8221;) issued by the Commissioner of Customs (Prev.),
    Mumbai, India (the &amp;#8220;Commissioner&amp;#8221;) in August&amp;#160;2003. The SCN concerned alleged violations of Indian
    customs laws and regulations regarding one of our jackups. The Commissioner alleged certain
    violations to have occurred before, at the time of, and after NACL acquired the rig from the rig&amp;#8217;s
    previous owner. In the purchase agreement for the rig, NACL received contractual indemnification
    against liability for Indian customs duty from the rig&amp;#8217;s previous owner. In connection with the
    export of the rig from India in 2001, NACL posted a bank guarantee in the amount of 150&amp;#160;million
    Indian Rupees (or $3&amp;#160;million at December&amp;#160;31, 2010) and a customs bond in the amount of 970&amp;#160;million
    Indian Rupees (or $22&amp;#160;million at December&amp;#160;31, 2010), both of which remain in place. In March&amp;#160;2005,
    the Commissioner passed an order against NACL and the other parties cited in the SCN seeking (i)&amp;#160;to
    invoke the bank guarantee posted on behalf of NACL as a fine, (ii)&amp;#160;to demand duty of (a) $19
    million plus interest related to a 1997 alleged import and (b) $22&amp;#160;million plus interest related to
    a 1999 alleged import,
    provided that the duty and interest demanded in (b) would not be payable if the duty and interest demanded in (a)&amp;#160;were paid by NACL, and (iii)&amp;#160;to
    assess a penalty of $500,000 against NACL. NACL appealed the order of the Commissioner to the
    Customs, Excise &amp;#038; Service Tax Appellate Tribunal (&amp;#8220;CESTAT&amp;#8221;). In 2006, CESTAT upheld NACL&amp;#8217;s appeal
    and overturned the Commissioner&amp;#8217;s March&amp;#160;2005 order against NACL in its entirety. The Commissioner
    filed an appeal in the Bombay High Court, which dismissed the appeal. In 2008, the Commissioner
    appealed to the Supreme Court of India, appealing the order of the Bombay High Court. NACL is
    opposing admission of the Appeal in the Supreme Court of India, and is seeking the return or
    cancellation of its previously posted custom bond and bank guarantee. NACL continues to pursue
    contractual indemnification against liability for Indian customs duty and related costs and
    expenses against the rig&amp;#8217;s previous owner in arbitration proceedings in London, which proceedings
    the parties have temporarily stayed pending further developments in the Indian proceeding. We do
    not believe the ultimate resolution of this matter will have a material adverse effect on our
    financial position, results of operations or cash flows.
    &lt;/div&gt;
    &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;In May&amp;#160;2010, Anadarko Petroleum Corporation (&amp;#8220;Anadarko&amp;#8221;) sent a letter asserting that the
    initial attempted deepwater drilling moratorium in the U.S. Gulf of Mexico, issued on May&amp;#160;28, 2010
    by U.S. Secretary of the Interior Ken Salazar, was an event of force majeure under the drilling
    contract for the &lt;i&gt;Noble Amos Runner&lt;/i&gt;. In June&amp;#160;2010, Anadarko filed a declaratory judgment action in
    Federal District Court in Houston, Texas seeking to have the court declare that a force majeure
    condition had occurred and that the drilling contract was terminated by virtue of the initial
    proclaimed moratorium. We disagree that a force majeure event occurred and that Anadarko had the
    right to terminate the contract. In August&amp;#160;2010, we filed a counterclaim seeking damages from
    Anadarko for breach of contract. We do not believe the ultimate resolution of this matter will
    have a material adverse effect on our financial position, results of operations or cash flows. Due
    to the uncertainties noted above, we have not recognized any revenue under the disputed portion of
    this contract. As the amounts in dispute have been fully reserved, the matter could have a
    material positive effect on our results of operations or cash flows in the period the matter is
    resolved.
    &lt;/div&gt;
    &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;The &lt;i&gt;Noble Homer Ferrington &lt;/i&gt;is under contract with a subsidiary of ExxonMobil Corporation
    (&amp;#8220;ExxonMobil&amp;#8221;), who entered into an assignment agreement with BP for a two well farmout of the rig
    in Libya after successfully drilling two wells with the rig for ExxonMobil. In August&amp;#160;2010, BP
    attempted to terminate the assignment agreement claiming that the rig was not in the required
    condition. ExxonMobil has informed us that we must look to BP for payment of the dayrate during
    the assignment period. In August&amp;#160;2010, we initiated arbitration proceedings under the drilling
    contract against both BP and ExxonMobil. We do not believe BP had the right to terminate the
    assignment agreement and believe the rig continues to be fully ready to operate under the drilling
    contract. We believe we are owed dayrate by either or both of these clients. The operating
    dayrate was approximately $538,000 per day for the work in Libya. We are proceeding with the
    arbitration process and intend to vigorously pursue these claims. Due to the uncertainties noted
    above, we have not recognized any revenue during the assignment period. We do not believe the
    ultimate resolution of these matters will have a material effect on our financial position. As the
    amounts in dispute have been fully reserved, the matter could have a material positive effect on
    our results of operations or cash flows in the period the matter is resolved.
    &lt;/div&gt;
    &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;We are from time to time a party to various lawsuits that are incidental to our operations in
    which the claimants seek an unspecified amount of monetary damages for personal injury, including
    injuries purportedly resulting from exposure to asbestos on drilling rigs and associated
    facilities. At December&amp;#160;31, 2010, there were approximately 36 of these lawsuits in which we are
    one of many defendants. These lawsuits have been filed in the United States in the states of
    Louisiana, Mississippi and Texas. We intend to defend vigorously against the litigation. We do
    not believe the ultimate resolution of these matters will have a material adverse effect on our
    financial position, results of operations or cash flows.
    &lt;/div&gt;
    &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;We are a defendant in certain claims and litigation arising out of operations in the ordinary
    course of business, including certain disputes with customers over receivables discussed in Note 5,
    the resolution of which, in the opinion of management, will not be material to our financial
    position, results of operations or cash flows. There is inherent risk in any litigation or dispute
    and no assurance can be given as to the outcome of these claims.

    &lt;/div&gt;
    &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;During the fourth quarter of 2007, our Nigerian subsidiary received letters from the Nigerian
    Maritime Administration and Safety Agency (&amp;#8220;NIMASA&amp;#8221;) seeking to collect a two percent surcharge on
    contract amounts under contracts performed by &amp;#8220;vessels,&amp;#8221; within the meaning of Nigeria&amp;#8217;s cabotage
    laws, engaged in the Nigerian coastal shipping trade. Although we do not believe that these laws
    apply to our ownership of drilling units, NIMASA is seeking to apply a provision of the Nigerian
    cabotage laws (which became effective on May&amp;#160;1, 2004) to our offshore drilling units by considering
    these units to be &amp;#8220;vessels&amp;#8221; within the meaning of those laws and therefore
    subject to the surcharge, which is imposed only upon &amp;#8220;vessels.&amp;#8221; Our offshore drilling units
    are not engaged in the Nigerian coastal shipping trade and are not in our view &amp;#8220;vessels&amp;#8221; within the
    meaning of Nigeria&amp;#8217;s cabotage laws. In January&amp;#160;2008, we filed an originating summons against
    NIMASA and the Minister of Transportation in the Federal High Court of Lagos, Nigeria seeking,
    among other things, a declaration that our drilling operations do not constitute &amp;#8220;coastal trade&amp;#8221; or
    &amp;#8220;cabotage&amp;#8221; within the meaning of Nigeria&amp;#8217;s cabotage laws and that our offshore drilling units are
    not &amp;#8220;vessels&amp;#8221; within the meaning of those laws. In February&amp;#160;2009, NIMASA filed suit against us in
    the Federal High Court of Nigeria seeking collection of the cabotage surcharge. In August&amp;#160;2009,
    the court issued a favorable ruling in response to our originating summons stating that drilling
    operations do not fall within the cabotage laws and that drilling rigs are not vessels for purposes
    of those laws. The court also issued an injunction against the defendants prohibiting their
    interference with our drilling rigs or drilling operations. NIMASA has appealed the court&amp;#8217;s
    ruling, although the court dismissed NIMASA&amp;#8217;s lawsuit filed against us in February&amp;#160;2009. We intend
    to take all further appropriate legal action to resist the application of Nigeria&amp;#8217;s cabotage laws
    to our drilling units. The outcome of any such legal action and the extent to which we may
    ultimately be responsible for the surcharge is uncertain. If it is ultimately determined that
    offshore drilling units constitute vessels within the meaning of the Nigerian cabotage laws, we may
    be required to pay the surcharge and comply with other aspects of the Nigerian cabotage laws, which
    could adversely affect our operations in Nigerian waters and require us to incur additional costs
    of compliance.
    &lt;/div&gt;
    &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;NIMASA had also informed the Nigerian Content Division of its position that we are not in
    compliance with the cabotage laws. The Nigerian Content Division makes determinations of
    companies&amp;#8217; compliance with applicable local content regulations for purposes of government
    contracting, including contracting for services in connection with oil and gas concessions where
    the Nigerian national oil company is a partner. The Nigerian Content Division had originally
    barred us from participating in new tenders as a result of NIMASA&amp;#8217;s allegations, although the
    Division reversed its actions based on the favorable Federal High Court ruling. However, no
    assurance can be given with respect to our ability to bid for future work in Nigeria until our
    dispute with NIMASA is resolved.
    &lt;/div&gt;
    &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;We operate in a number of countries throughout the world and our income tax returns filed in
    those jurisdictions are subject to review and examination by tax authorities within those
    jurisdictions. We have been informed by the U.S. Internal Revenue Service that our 2008 tax return
    is currently under audit. In addition, a U.S. subsidiary of Frontier is also under audit for its
    2007 and 2008 tax returns. Furthermore, we are currently contesting several non-U.S. tax
    assessments and may contest future assessments when we believe the assessments are in error. We
    cannot predict or provide assurance as to the ultimate outcome of the existing or future
    assessments. We believe the ultimate resolution of the outstanding assessments, for which we have
    not made any accrual, will not have a material adverse effect on our consolidated financial
    statements. We recognize uncertain tax positions that we believe have a greater than 50&amp;#160;percent
    likelihood of being sustained.
    &lt;/div&gt;
    &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;Certain of our non-U.S. income tax returns have been examined for the 2002 through 2008
    periods and audit claims have been assessed for approximately $305&amp;#160;million (including interest and
    penalties), primarily in Mexico. We do not believe we owe these amounts and are defending our
    position. However, we expect increased audit activity in Mexico and anticipate the tax authorities
    will issue additional assessments and continue to pursue legal actions for all audit claims. We
    believe additional audit claims in the range of $16 to $18&amp;#160;million attributable to other business
    tax returns may be assessed against us. We have contested, or intend to contest, the audit
    findings, including through litigation if necessary, and we do not believe that there is greater
    than 50&amp;#160;percent likelihood that additional taxes will be incurred. Accordingly, no accrual has
    been made for such amounts.
    &lt;/div&gt;
    &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;We maintain certain insurance coverage against specified marine perils, including liability
    for physical damage to our drilling rigs, and loss of hire on certain of our rigs. The damage
    caused in 2005 and 2008 by Hurricanes Katrina, Rita and Ike to oil and gas assets situated in the
    U.S. Gulf of Mexico negatively impacted the energy insurance market, resulting in more restricted
    and more expensive coverage. We also cannot predict what the impact of the recent events in the
    U.S. Gulf of Mexico will have on the cost or availability of future insurance coverage. We
    evaluate and renew our operational insurance policies on a yearly basis during the month of March.
    &lt;/div&gt;
    &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;We have elected to self insure U.S. named windstorm physical damage and loss of hire exposures
    due to the high cost of coverage for these perils. This self insurance applies only to our units
    in the U.S. portion of the Gulf of Mexico. Our rigs located in the Mexican portion of the Gulf of
    Mexico remain covered by commercial insurance for windstorm damage. In addition, we maintain
    physical damage deductibles of $25&amp;#160;million per occurrence for rigs located in the U.S., Mexico,
    Brazil, Southeast Asia and the North Sea and $15&amp;#160;million per occurrence for rigs operating in West
    Africa, the Middle East, India, and the Mediterranean Sea. The loss of hire coverage applies only
    to our rigs operating under contract with a dayrate equal to or greater than $200,000 a day
    and is subject to a 45-day waiting period for each unit and each occurrence.
    &lt;/div&gt;

    &lt;/div&gt;
    &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;Although we maintain insurance in the geographic areas in which we operate, pollution,
    reservoir damage and environmental risks generally are not fully insurable. Our insurance policies
    and contractual rights to indemnity may not adequately cover our losses or may have exclusions of
    coverage for some losses. We do not have insurance coverage or rights to indemnity for all risks,
    including loss of hire insurance on most of the rigs in our fleet. Uninsured exposures may include
    expatriate activities prohibited by U.S. laws and regulations, radiation hazards, certain loss or
    damage to property onboard our rigs and losses relating to shore-based terrorist acts or strikes.
    If a significant accident or other event occurs and is not fully covered by insurance or
    contractual indemnity, it could adversely affect our financial position, results of operations or
    cash flows. Additionally, there can be no assurance that those parties with contractual
    obligations to indemnify us will necessarily be financially able to indemnify us against all these
    risks.
    &lt;/div&gt;
    &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;We carry protection and indemnity insurance covering marine third party liability exposures,
    which also includes coverage for employer&amp;#8217;s liability resulting from personal injury to our
    offshore drilling crews. Our protection and indemnity policy currently has a standard deductible
    of $10&amp;#160;million per occurrence, with maximum liability coverage of $750&amp;#160;million.
    &lt;/div&gt;
    &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;In connection with our capital expenditure program, we had outstanding commitments, including
    shipyard and purchase commitments of approximately $1.5&amp;#160;billion at December&amp;#160;31, 2010.
    Subsequent to December&amp;#160;31, 2010, we entered into shipyard commitments of approximately $1.0&amp;#160;billion
    in connection with the signing of construction contracts for two additional newbuild drillships,
    and canceled shipyard contracts totaling $77&amp;#160;million in connection with the decision not to proceed
    with the reliability upgrade on the &lt;i&gt;Noble Muravlenko&lt;/i&gt;. See Note 19, &amp;#8220;&lt;i&gt;Subsequent Events,&lt;/i&gt;&amp;#8221; for
    additional information regarding these transactions.
    &lt;/div&gt;
    &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;We have entered into agreements with certain of our executive officers, as well as certain
    other employees. These agreements become effective upon a change of control of Noble-Swiss (within
    the meaning set forth in the agreements) or a termination of employment in connection with or in
    anticipation of a change of control, and remain effective for three years thereafter. These
    agreements provide for compensation and certain other benefits under such circumstances.
    &lt;/div&gt;
    &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt"&gt;&lt;b&gt;&lt;i&gt;Internal Investigation&lt;/i&gt;&lt;/b&gt;
    &lt;/div&gt;
    &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;In 2007, we began, and voluntarily contacted the SEC and the U.S. Department of Justice
    (&amp;#8220;DOJ&amp;#8221;) to advise them of, an internal investigation of the legality under the United States
    Foreign Corrupt Practices Act (&amp;#8220;FCPA&amp;#8221;) and local laws of certain reimbursement payments made by our
    Nigerian affiliate to our customs agents in Nigeria. In November&amp;#160;2010, we finalized settlements of
    this matter with each of the SEC and the DOJ. In order to resolve the DOJ investigation, we
    entered into a non-prosecution agreement with the DOJ, which provides for the payment of a fine of
    $2.6&amp;#160;million, as well as certain undertakings, including continued cooperation with the DOJ,
    compliance with the FCPA, certain self-reporting and annual reporting obligations and certain
    restrictions on our public discussion regarding the agreement. The agreement does not require that
    we install a monitor to oversee our activities and compliance with laws. In order to resolve the
    SEC investigation, we agreed to the entry of a civil judgment against us for violations of the
    FCPA. Pursuant to the agreed judgment, we agreed to disgorge profits of $4.3&amp;#160;million, pay
    prejudgment interest of $1.3&amp;#160;million and refrain from denying the allegations contained in the
    SEC&amp;#8217;s petition, except in other litigation to which the SEC is not a party. We also agreed to an
    injunction restraining us from violating the anti-bribery, books and records, and internal controls
    provisions of the FCPA, and we waived a variety of litigation rights with respect to the conduct at
    issue. The agreed judgment does not require a monitor. Our ability to comply with the terms of
    the settlements is dependent on the success of our ongoing compliance program, including our
    ability to continue to manage our agents and supervise, train and retain competent employees, and
    the efforts of our employees to comply with applicable law and our code of business conduct and
    ethics.
    &lt;/div&gt;
    &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;In January&amp;#160;2011, the Nigerian Economic and Financial Crimes Commission and the Nigerian
    Attorney General Office initiated an investigation into these same activities. A subsidiary of
    Noble-Swiss resolved this matter through the execution of a non-prosecution agreement dated January
    28, 2011. Pursuant to this agreement, the subsidiary paid $2.5&amp;#160;million to resolve all charges and
    claims of the Nigerian government. Any additional sanctions we may incur as a result of any such
    investigation could damage our reputation and result in substantial fines, sanctions, civil and/or
    criminal penalties and curtailment of operations in certain jurisdictions and might adversely
    affect our business, results of operations or financial condition. Further, resolving any such
    investigation could be expensive and consume significant time and attention of our senior
    management.

    We have one jackup rig in Nigeria which is operating under a
    temporary import permit which expired in November 2008 and we have a
    pending application to renew this permit.  We have received approval
    from the Nigerian Customs office that we will be allowed to obtain a
    new temporary import permit for this rig. We recently received a new
    temporary import permit for another rig in Nigeria that had been
    waiting for a temporary import permit based on a long-standing
    application. We continue to seek to avoid material disruption to our Nigerian
    operations; however, there can be no assurance that we will be able to obtain new permits or
    further extensions of permits necessary to continue the operation of our rigs in Nigeria. If we
    cannot obtain a new permit or an extension necessary to continue operations of any rig, we may need
    to cease operations under the drilling contract for such rig and relocate such rig from Nigerian
    waters. We cannot predict what impact these events may have on any such contract or our business
    in Nigeria, and we could face additional fines and sanctions in Nigeria. Furthermore, we cannot
    predict what changes, if any, relating to temporary import permit policies and procedures may be
    established or implemented in Nigeria in the future, or how any such changes may impact our
    business there.
