   &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 June&amp;#160;30, 2010) and a customs bond in the amount of 970&amp;#160;million
   Indian Rupees (or $21&amp;#160;million at June&amp;#160;30, 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)&amp;#160;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;). At a hearing on April&amp;#160;5, 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. CESTAT thereafter
   issued its written judgment dated August&amp;#160;8, 2006 upholding NACL&amp;#8217;s appeal on all grounds and setting
   aside the duty demand, interest, fine and penalty. The Commissioner filed an appeal in the Bombay
   High Court challenging the order passed by CESTAT. In August&amp;#160;2008, the Division Bench of the
   Bombay High Court dismissed the Commissioner&amp;#8217;s appeal of CESTAT&amp;#8217;s order. In November&amp;#160;2008, the
   Commissioner filed a Special Leave Petition, an Appeal in the Supreme Court of India, appealing the
   order of the Bombay High Court. NACL has filed an Affidavit-in-reply 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;.&amp;#160; 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.&amp;#160;
   We disagree that a force majeure event occurred and that Anadarko had the right
   to terminate the contract.&amp;#160; In August&amp;#160;2010, we filed a counterclaim
   seeking damages from Anadarko for breach of contract.&amp;#160; 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.

   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 June&amp;#160;30, 2010, there were approximately 39 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, the resolution of which, in the opinion of management, will not be material to
   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;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 recently been informed by the U.S. Internal Revenue Service that our 2008
   tax return is currently under audit. In addition, 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 2004
   periods and audit claims have been assessed for approximately $191&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 $21 to $23&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 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 on the
   &lt;i&gt;Deepwater Horizon&lt;/i&gt;, a competitor&amp;#8217;s drilling rig 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. As of June&amp;#160;30, 2010 we maintained six semisubmersibles
   and two submersibles in the U.S. 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, Singapore 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 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
   war risk, activities prohibited by U.S. laws and regulations, radiation hazards, certain loss or
   damage to property on board our rigs and losses relating to 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.
   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 $904&amp;#160;million at June&amp;#160;30, 2010.
   &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 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 customs agents in Nigeria. The SEC and the DOJ have indicated that they
   believe that violations of the FCPA occurred and will seek civil and/or criminal sanctions against
   us, including monetary penalties, and may include additional sanctions against us and/or certain of
   our employees, as well as additional changes to our business practices and compliance programs. We
   could also face fines or sanctions in relevant foreign jurisdictions.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;We consider the matter relating to the Nigeria investigation to be ongoing and cannot predict
   (a)&amp;#160;when it will conclude, (b)&amp;#160;whether either the SEC or the DOJ will open its own proceeding to
   investigate this matter, or (c)&amp;#160;if a proceeding is opened, what potential sanctions, penalties or
   other remedies these agencies may seek. Based on information obtained to date, we believe it is
   probable that we will pay an amount to settle this matter with the DOJ and SEC. Given that the
   matter is not finally resolved, we cannot predict with certainty what amount we will pay in civil
   and criminal fines and penalties; however, in June&amp;#160;2010, we accrued a settlement provision of
   approximately $5&amp;#160;million relating to this ongoing matter. Any of the sanctions as a result of the
   Nigerian investigation or any other future violation of the FCPA or similar law could have a
   material adverse effect on our business or financial condition and could damage our reputation and
   ability to do business, to attract and retain employees and to access capital markets.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;Notwithstanding that the investigation is ongoing, we concluded that certain changes to our
   FCPA compliance program would provide us greater assurance that our assets are not used, directly
   or indirectly, to make improper payments, including customs payments, and that we are in compliance
   with the FCPA&amp;#8217;s record-keeping requirements. Although we have had a long-standing published policy
   requiring compliance with the FCPA and broadly prohibiting any improper payments by us to foreign
   or U.S. officials, we adopted additional measures intended to enhance FCPA compliance procedures.
   Further measures may be required once the investigation matter is concluded.
   &lt;/div&gt;
   &lt;div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 8%"&gt;We are currently operating three jackup rigs offshore Nigeria. The temporary import permits
   covering two of these rigs expired in November&amp;#160;2008 and we have pending applications to renew these
   permits. However, as of July&amp;#160;31, 2010, the Nigerian customs office had not acted on our
   applications. We have obtained a temporary import permit for the third rig which was imported into
   the country in 2009. 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. In any case,
   we also could be subject to actions by Nigerian customs for import duties and fines for these two
   rigs, as well as other drilling rigs that operated in Nigeria in the past. We cannot predict what
   impact these events may have on any such contract or our business 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.
