     (iii) any such free writing prospectus the use of which has been consented to by the Company and ▇▇▇▇▇▇▇, ▇▇▇▇▇ & Co. (including the final term sheet prepared and filed pursuant to Section 5(a) hereof) is listed on Schedule II(a) hereto;

     (b) The Company and the Parent Guarantor have complied and will comply with the requirements of Rule 433 under the Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission or retention where required and legending; and

     (c) The Company and the Parent Guarantor agree that, if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, the Pricing Prospectus or the Prospectus or would include

an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, the Company or the Parent Guarantor will give prompt notice thereof to ▇▇▇▇▇▇▇, Sachs & Co. and, if requested by ▇▇▇▇▇▇▇, ▇▇▇▇▇ & Co., will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus or other document that will correct such conflict, statement or omission; provided, however, that this agreement shall not apply to any statements or omissions in an Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the Company by an Underwriter through ▇▇▇▇▇▇▇, Sachs & Co., Citigroup Global Markets Inc. or SunTrust ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇, Inc. expressly for use therein.

     7. The Company covenants and agrees with the several Underwriters that the Company will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Company’s counsel and accountants in connection with the registration of the Securities and the Guarantee under the Act and all other expenses in connection with the preparation, printing, reproduction and filing of the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, any Issuer Free Writing Prospectus and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and dealers; (ii) the cost of printing or producing this Agreement, the Indenture, the Blue Sky Memorandum, closing documents (including any compilations thereof) and any other documents in connection with the offering, purchase, sale and delivery of the Securities and the Guarantee; (iii) any expenses in connection with the qualification of the Securities and the Guarantee for offering and sale under state securities laws as provided in Section 5(d) hereof, including the fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky survey; (iv) any fees charged by securities rating services for rating the Securities; (v) the filing fees incident to, and the fees and disbursements of counsel for the Underwriters in connection with, any required review by the Financial Industry Regulatory Authority of the terms of the sale of the Securities and the Guarantee; (vi) the cost of preparing the Securities and the Guarantee; (vii) the fees and expenses of the Trustee and any agent of the Trustee and the fees and disbursements of counsel for the Trustee in connection with the Indenture, the Securities and the Guarantee; and (viii) all other costs and expenses incident to the performance of its obligations hereunder that are not otherwise specifically provided for in this Section. It is understood, however, that, except as provided in this Section, and Sections 9 and 12 hereof, the Underwriters will pay all of their own costs and expenses, including the fees of their counsel, transfer taxes on resale of any of the Securities by them, and any advertising expenses connected with any offers they may make.

     8. The obligations of the Underwriters hereunder shall be subject, in their discretion, to the condition that all representations and warranties and other statements of the Company and the Parent Guarantor herein are, at and as of the Time of Delivery, true and correct, the condition that the Company and the Parent Guarantor shall have performed all of its obligations hereunder theretofore to be performed, and the following additional conditions:

     (a) The Prospectus shall have been filed with the Commission pursuant to Rule 424(b) under the Act within the applicable time period prescribed for such filing by the rules and regulations under the Act and in accordance with Section 5(a) hereof; the final term sheet contemplated by Section 5(a) hereof, and any other material required to

     (b) ▇▇▇▇▇▇ & ▇▇▇▇▇▇ LLP, counsel for the Underwriters, shall have furnished to you such written opinion or opinions, dated the Time of Delivery, in form and substance satisfactory to you, with respect to certain matters as you may reasonably request, and such counsel shall have received such papers and information as they may reasonably request to enable them to pass upon such matters;

     (c) ▇▇▇▇▇ ▇▇▇▇▇ L.L.P., counsel for the Company and the Parent Guarantor, shall have furnished to you their written legal opinion letter, dated the Time of Delivery, in form and substance satisfactory to you, and substantially as set forth on Annex II(a) hereto:

     (d) ▇▇▇▇▇▇ and Calder, Cayman Islands counsel for the Company and the Parent Guarantor, shall have furnished to you their written legal opinion letter, dated the Time of Delivery, in form and substance satisfactory to you, and substantially as set forth on Annex II(b) hereto.

     (e) On the date of the Prospectus at a time prior to the execution of this Agreement, at 9:30 a.m., New York City time, on the effective date of any post effective amendment to the Registration Statement filed subsequent to the date of this Agreement and also at the Time of Delivery, PricewaterhouseCoopers LLP shall have furnished to you a letter or letters, dated the respective dates of delivery thereof, in form and substance satisfactory to you, to the effect set forth in Annex I hereto (the executed copy of the letter delivered prior to the execution of this Agreement is attached as Annex I(a) hereto and a form of letter to be delivered on the effective date of any post-effective amendment to the Registration Statement, and as of the Time of Delivery is attached as Annex I(b) hereto);

     (f) (i) Neither the Parent Guarantor nor any of its subsidiaries shall have sustained since the date of the latest audited financial statements included or incorporated by reference in the Pricing Prospectus any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Pricing Prospectus, and (ii) since the respective dates as of which information is given in the Pricing Prospectus there shall not have been any change in the capital stock or long-term debt of the Parent Guarantor or any of its subsidiaries (other

than changes due to repurchases of the Parent Guarantor’s ordinary shares under the Parent Guarantor’s announced share repurchase program and changes, if any, in the ordinary course of business, (i) in amounts outstanding under the Parent Guarantor’s unsecured revolving credit facility or (ii) due to issuances of the Parent Guarantor’s ordinary shares under the Parent Guarantor’s share-based employee benefit and options plans) or any change, or any development involving a prospective change, in or affecting the general affairs, management, financial position, stockholders’ equity or results of operations of the Parent Guarantor and its subsidiaries, otherwise than as set forth or contemplated in the Pricing Prospectus, the effect of which, in any such case described in clause (i) or (ii), is in your judgment so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated in the Prospectus;

     (g) On or after the Applicable Time (i) no downgrading shall have occurred in the rating accorded the debt securities of the Company or the Parent Guarantor by any “nationally recognized statistical rating organization”, as that term is defined by the Commission for purposes of Rule 436(g)(2) under the Act, and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any such debt securities;

     (h) On or after the Applicable Time there shall not have occurred any of the following: (i) a suspension or material limitation in trading in securities generally on the New York Stock Exchange; (ii) a suspension or material limitation in trading in the Parent Guarantor’s securities on the New York Stock Exchange; (iii) a general moratorium on commercial banking activities declared by either Federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States; (iv) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war or (v) the occurrence of any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, if the effect of any such event specified in clause (iv) or (v) in your judgment makes it impracticable or inadvisable to proceed with the public offering or the delivery of the Securities on the terms and in the manner contemplated in the Prospectus;

     (i) The Company and the Parent Guarantor shall have complied with the provisions of Section 5(e) hereof with respect to the furnishing of prospectuses on the New York Business Day next succeeding the date of this Agreement; and

     (j) The Company and the Parent Guarantor shall have furnished or caused to be furnished to you at the Time of Delivery certificates of officers of the Company and the Parent Guarantor, respectively, satisfactory to you as to the accuracy of the respective representations and warranties of the Company and the Parent Guarantor herein at and as of such time, as to the performance by the Company and the Parent Guarantor of all of their respective obligations hereunder to be performed at or prior to such time, as to the matters set forth in subsections (a) and (f) of this Section and as to such other matters as you may reasonably request.

     9. (a) The Company and the Parent Guarantor will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that neither the Company nor the Parent Guarantor shall be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company or the Parent Guarantor by any Underwriter through ▇▇▇▇▇▇▇, ▇▇▇▇▇ & Co. expressly for use therein.

     (b) Each Underwriter will indemnify and hold harmless the Company and the Parent Guarantor against any losses, claims, damages or liabilities to which the Company or the Parent Guarantor may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus or any such amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company or the Parent Guarantor by such Underwriter through ▇▇▇▇▇▇▇, Sachs & Co. expressly for use therein; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred.

     (c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability that it may have to any indemnified party otherwise than under such subsection. In case any

such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

     (d) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other, from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Parent Guarantor, on the one hand, and the Underwriters, on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company, on the one hand, and the Underwriters, on the other, shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Parent Guarantor, on the one hand, or the Underwriters, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Parent Guarantor and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (d) were

determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

     (e) The obligations of the Company and the Parent Guarantor under this Section 9 shall be in addition to any liability that the Company or the Parent Guarantor may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act and each broker-dealer affiliate of any Underwriter; and the obligations of the Underwriters under this Section 9 shall be in addition to any liability that the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and the Parent Guarantor and to each person, if any, who controls the Company or the Parent Guarantor within the meaning of the Act.

     10. (a) If any Underwriter shall default in its obligation to purchase the Securities that it has agreed to purchase hereunder, you may in your discretion arrange for you or another party or other parties to purchase such Securities on the terms contained herein. If within 36 hours after such default by any Underwriter you do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure another party or other parties satisfactory to you to purchase such Securities on such terms. In the event that, within the respective prescribed periods, you notify the Company that you have so arranged for the purchase of such Securities, or the Company notifies you that it has so arranged for the purchase of such Securities, you or the Company shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company and the Parent Guarantor agree to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in your opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Securities.

     (b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities that such Underwriter agreed to purchase hereunder and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Securities which such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

     (c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate principal amount of Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Securities of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter, the Company or the Parent Guarantor, except for the expenses to be borne by the Company and the Underwriters as provided in Section 7 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

     11. The respective indemnities, agreements, representations, warranties and other statements of the Company, the Parent Guarantor and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, the Company or any officer or director or controlling person of the Company or the Parent Guarantor or any officer or director or controlling person of the Parent Guarantor, and shall survive delivery of and payment for the Securities.

     12. If this Agreement shall be terminated pursuant to Section 10 hereof, neither the Company nor the Parent Guarantor shall then be under any liability to any Underwriter except as provided in Sections 7 and 9 hereof; but, if for any other reason, the Securities and the Guarantee are not delivered by or on behalf of the Company and the Parent Guarantor as provided herein, the Company will reimburse the Underwriters through you for all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Securities, but neither the Company nor the Parent Guarantor shall then be under further liability to any Underwriter except as provided in Sections 7 and 9 hereof.

     13. In all dealings hereunder, you shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or

agreement on behalf of any Underwriter made or given by you jointly or by ▇▇▇▇▇▇▇, ▇▇▇▇▇ & Co. on behalf of you as the representatives.

     14. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to you as representatives in care of ▇▇▇▇▇▇▇, Sachs & Co., ▇▇▇ ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: Registration Department; and if to the Company or the Parent Guarantor shall be delivered or sent by mail, telex or facsimile transmission to the address of the Parent Guarantor set forth in the Registration Statement, Attention: Secretary; provided, however, that any notice to an Underwriter pursuant to Section 9(c) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Company and the Parent Guarantor by you upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

     15. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company, the Parent Guarantor and, to the extent provided in Sections 9 and 11 hereof, the officers and directors of the Company and the Parent Guarantor and each person who controls the Company or the Parent Guarantor or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Securities from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

     16. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

     17. The Company and the Parent Guarantor acknowledge and agree that (i) the purchase and sale of the Securities and the Guarantee pursuant to this Agreement is an arm’s-length commercial transaction between the Company and the Parent Guarantor, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction, each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company or the Parent Guarantor, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company or the Parent Guarantor with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company or the Parent Guarantor on other matters) or any other obligation to the Company or the Parent Guarantor except the obligations expressly set forth in this Agreement or any other effective agreement between you and the Company or the Parent Guarantor and (iv) the Company and the Parent Guarantor have consulted their own legal and financial advisors to the extent they deemed appropriate. The Company and the Parent Guarantor agree that they will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company or the Parent Guarantor, in connection with such transaction or the process leading thereto.

     18. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company or the Parent Guarantor, on the one hand, and the Underwriters, or any of them, on the other, with respect to the subject matter hereof.

     19. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

     20. The Company, the Parent Guarantor and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

     21. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.

     22. Notwithstanding anything herein to the contrary, the Company and the Parent Guarantor are authorized to disclose to any persons the U.S. federal and state income tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided to the Company or the Parent Guarantor relating to that treatment and structure without the Underwriters imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, “tax structure” is limited to any facts that may be relevant to that treatment.

     If the foregoing is in accordance with your understanding, please sign and return to us four counterparts hereof, and upon the acceptance hereof by you, on behalf of each of the Underwriters, this letter and such acceptance hereof shall constitute a binding agreement among each of the Underwriters, the Company and the Parent Guarantor. It is understood that your acceptance of this letter on behalf of each of the Underwriters is pursuant to the authority set forth in a form of Agreement among Underwriters, the form of which shall be submitted to the Company for examination upon request, but without warranty on your part as to the authority of the signers thereof.

Ladies and Gentlemen:

We have audited:

	1.		the consolidated financial statements of Noble Corporation (the “Company”) and subsidiaries as of December 31, 2007 and 2006 and for each of the three years in the period ended December 31, 2007 included in the Company’s annual report on Form 10-K for the year ended December 31, 2007 (the “Form 10-K”), which have been recast to include the historical results of Noble Holding International Limited (“NHIL”) as a stand alone entity as of December 31, 2007 and 2006 and for each of the three years in the period ended December 31, 2007 as reported on Note 19 of the consolidated financials statements included on the Company’s current report on Form 8-K dated November 18, 2008 (the “Form 8-K”), and
	2.		the effectiveness of the Company’s internal control over financial reporting as of December 31, 2007.

The consolidated financial statements referred to above are all incorporated by reference in the registration statement (No. 333-155421-02) on Form S-3 filed by the Company under the Securities Act of 1933 (the “Act”); our report with respect thereto is also incorporated by reference in such registration statement. Such registration statement, including the prospectus and the preliminary prospectus supplement, both dated November 18, 2008, is herein referred to as the “Registration Statement.”

In connection with the Registration Statement:

1.		We are an independent registered public accounting firm with respect to the Company within the meaning of the Act and the applicable rules and regulations thereunder adopted by the Securities and Exchange Commission (“SEC”) and the Public Company Accounting Oversight Board (United States) (“PCAOB”).
2.		In our opinion, the consolidated financial statements audited by us and incorporated by reference in the Registration Statement comply as to form in all material respects with the applicable accounting requirements of the Act and the Securities Exchange Act of 1934 and the related rules and regulations adopted by the SEC.
3.		We have not audited any financial statements of the Company as of any date or for any period subsequent to December 31, 2007; although we have conducted an audit for the year ended December 31, 2007, the purpose (and therefore the scope) of such audit was to enable us to express our opinion on the consolidated financial statements as of December 31, 2007 and for the year then ended, but not on the financial statements for any interim period within such year. Therefore, we are unable to and do not express any opinion on the unaudited consolidated balance sheets and the unaudited consolidated statements of income, of cash flows, of shareholders’ equity and of comprehensive income included in the Company’s quarterly reports on Form 10-Q for the quarters ended March 31, 2008, June 30, 2008 and September 30, 2008, incorporated by reference in the Registration Statement, or on the financial position, results of operations or cash flows as of any date or for any period subsequent to December 31, 2007. Also, we have not audited the Company’s internal control over financial reporting as of any date subsequent to December 31, 2007. Therefore, we do not express any opinion on the Company’s internal control over financial reporting as of any date subsequent to December 31, 2007.
4.		For purposes of this letter, we have read the minutes of the 2008 meetings of the shareholders, the Board of Directors, and the Audit, Finance, Compensation, and Nominating and Corporate Governance Committees of the Company and its subsidiaries as set forth in the minute books at November 14, 2008, officials of the Company having advised us that the minutes of all such meetings through that date were set forth therein (except for those listed in Exhibit I, which were not approved in final form, for which drafts were provided to us; officials of the Company have represented that such drafts include all substantive actions taken at such meetings), and have carried out other procedures to November 14, 2008 (our work did not extend to the period from November 15, 2008 to November 18, 2008, inclusive) as follows:

a.

With respect to the three-month, three- and six-month, and three- and nine-month periods ended March 31, 2008 and 2007, June 30, 2008 and 2007 and September 30, 2008 and 2007, respectively, we have:

(i)

performed the procedures (completed on May 9, 2008, August 8, 2008 and November 7, 2008, respectively) specified by the PCAOB for a review of interim financial information as described in SAS No. 100, Interim Financial Information, on the unaudited consolidated financial statements as of and for the three-month periods ended March 31, 2008 and 2007, three- and six-month periods ended June 30, 2008 and 2007, and three- and nine-month periods ended September 30, 2008 and 2007 included in the Company’s quarterly reports on Form 10-Q for the quarters ended March 31, 2008, June 30, 2008 and September 30, 2008, respectively, incorporated

			by reference in the Registration Statement; and
	(ii)		inquired of certain officials of the Company who have responsibility for financial and accounting matters whether the unaudited consolidated financial statements referred to in a.(i) above comply as to form in all material respects with the applicable accounting requirements of the Securities Exchange Act of 1934 as it applies to Form 10-Q and the related rules and regulations adopted by the SEC.

b.

With respect to the period from October 1, 2008 to October 31, 2008, we have:

	(i)		read the unaudited consolidated financial data of the Company and subsidiaries for October of both 2008 and 2007 furnished us by the Company, officials of the Company having advised us that no such financial data as of any date or for any period subsequent to October 31, 2008 were available. The financial information for October of both 2008 and 2007 is incomplete in that it omits the statement of cash flows, of shareholders’ equity and of comprehensive income and other disclosures.
	(ii)		inquired of certain officials of the Company who have responsibility for financial and accounting matters as to whether the unaudited consolidated financial data referred to in b.(i) above are stated on a basis substantially consistent with that of the audited consolidated financial statements incorporated by reference in the Registration Statement.

		The foregoing procedures do not constitute an audit made in accordance with standards of the PCAOB. Also, they would not necessarily reveal matters of significance with respect to the comments in the following paragraph. Accordingly, we make no representations as to the sufficiency of the foregoing procedures for your purposes.
5.		It should be noted effective January 1, 2008, the Company partially adopted SFAS No. 157, Fair Value Measurements. Nothing came to our attention as a result of the foregoing procedures, however, that caused us to believe that:

		a.		(i)		Any material modifications should be made to the unaudited consolidated financial statements described in 4.a.(i), incorporated by reference in the Registration Statement, for them to be in conformity with generally accepted accounting principles.

(ii)

The unaudited consolidated financial statements described in 4.a.(i) do not comply as to form in all material respects with the applicable accounting requirements of the Securities Exchange Act of 1934 as it applies to Form 10-Q and the related rules and regulations adopted by the SEC.

		b.		(i)		At October 31, 2008 there was any change in the ordinary shares, increase in long-term debt, or decrease in consolidated net current assets (working capital) or shareholders’ equity of the Company and subsidiaries consolidated as compared with amounts shown in the September 30, 2008 unaudited consolidated balance sheet incorporated by reference in the Registration Statement, except that the unaudited consolidated balance sheet as of October 31, 2008, which we were furnished by the Company showed a change from September 30, 2008 in the ordinary shares and an

increase in long-term debt as disclosed in Exhibit II of this letter, or (ii) for the period from October 1, 2008 to October 31, 2008, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated operating revenues or in the total or per-share amounts of consolidated net income, except in all instances for changes, increases or decreases which the Registration Statement discloses have occurred or may occur.

6.		As mentioned in 4.b., Company officials have advised us that no consolidated financial data as of any date or for any period subsequent to October 31, 2008 are available; accordingly, the procedures carried out by us with respect to changes in financial statement items after October 31, 2008 have, of necessity, been even more limited than those with respect to the periods referred to in 4. We have inquired of certain officials of the Company who have responsibility for financial and accounting matters as to whether (a) at November 14, 2008 there was any change in the ordinary shares, increase in long-term debt of the Company and subsidiaries consolidated as compared with amounts shown in the September 30, 2008 unaudited consolidated balance sheet incorporated by reference in the Registration Statement; or (b) for the period from October 1, 2008 to November 14, 2008, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated operating revenues or in the total or per-share amounts of consolidated net income. On the basis of these inquiries and our reading of the minutes as described in 4, nothing came to our attention that caused us to believe that there was any such change, increase or decrease, except in all instances for changes, increases or decreases which the Registration Statement discloses have occurred or may occur.
7.		For purposes of this letter, we have also read the items identified by you on the attached copy of the preliminary prospectus supplement (Exhibit III) forming part of the Registration Statement and the attached copies of the documents incorporated by reference in the Registration Statement which include, the Company’s Form 8-K for the year ended December 31, 2007 (Exhibit IV), the Company’s quarterly report filed on Form 10-Q for the quarters ended March 31, 2008 (Exhibit V), June 30, 2008 (Exhibit VI), and September 30, 2008 (Exhibit VII), and have performed the following procedures, which were applied as indicated with respect to the numbers explained below. We make no comment as to whether the SEC would view any non-GAAP financial information included or incorporated by reference in this document as being compliant with the requirements of Regulation G or Item 10 of Regulation S-K.

	1		Compared the amount to corresponding amounts in the Company’s audited consolidated financial statements as of December 31, 2007 and 2006 and for each of the three years in the period ended December 31, 2007 or the notes thereto, included in the Form 8-K dated November 18, 2008, incorporated by reference in the Registration Statement described in the first paragraph of this letter, and found such amount to be in agreement.
	2		Recomputed the amount or percentage using amounts contained in the Company’s audited consolidated financial statements as of December 31, 2007 and 2006 and for each of the three years in the period ended December 31, 2007 or the notes thereto, included in the Form 8-K dated

			November 18, 2008, incorporated by reference in the Registration Statement, and found such amount or percentage to be in agreement.
	3		Compared the amount or percentage to or recomputed the amount or percentage based on a Company-prepared schedule, derived from the Company’s accounting records, and found such amount or percentage to be in agreement. We (a) compared the amounts on the schedule to corresponding amounts appearing in the Company’s accounting records and found such amounts to be in agreement, and (b) determined that the schedule was mathematically correct.
	4		Compared the amount to corresponding amounts in the Company’s unaudited consolidated financial statements and/or the related notes thereto, included in the March 31, 2008, June 30, 2008 or September 30, 2008 Form 10-Q incorporated by reference in the Registration Statement described in paragraph 4a of this letter, and found such amount to be in agreement.
	5		Recomputed the amount or percentage using amounts contained in the Company’s unaudited consolidated financial statements and/or the related notes thereto, included in the March 31, 2008, June 30, 2008 or September 30, 2008 Form 10-Q incorporated by reference in the Registration Statement described in paragraph 4a of this letter, and found such amount to be in agreement.
	6		Compared the ratios of earnings to fixed charges to ratios included on a Company-prepared schedule, derived from the Company’s accounting records, and found such ratios to be in agreement. We (a) compared the amounts on the schedule to corresponding amounts appearing in the Company’s accounting records and found such amounts to be in agreement, and (b) determined that the schedule was mathematically correct. However, we make no comment as to the Company’s compliance with the disclosure requirements of Item 503(d) of Regulation S-K or the appropriateness of management’s use of one-third (1/3) of rent expense as the interest factor.

8.

Our audit of the consolidated financial statements for the periods referred to in the introductory paragraph of this letter comprised audit tests and procedures deemed necessary for the purpose of expressing an opinion on such financial statements taken as a whole. For none of the periods referred to therein, or any other period, did we perform audit tests for the purpose of expressing an opinion on individual balances of accounts or summaries of selected transactions such as those enumerated above, and, accordingly, we express no opinion thereon.

9.		It should be understood that we make no representations regarding questions of legal interpretation or regarding the sufficiency for your purposes of the procedures enumerated in the second preceding paragraph; also, such procedures would not necessarily reveal any material misstatement of the amounts or percentages listed above. Further, we have addressed ourselves solely to the foregoing data as set forth in the Registration Statement and make no representations regarding the adequacy of disclosure or regarding whether any material facts have been omitted.
10.		This letter is solely for the information of the addressees and to assist the underwriters in conducting and documenting their investigation of the affairs of the Company in connection with the offering of the securities covered by the Registration Statement, and is not to be used, circulated, quoted, or otherwise referred to within or without the underwriting group for any other purpose, including but not limited to the registration, purchase, or sale of securities, nor is it to be filed with or referred to in whole or in part in the Registration Statement or any other document, except that reference may be made to it in the underwriting agreement or in any list of closing documents pertaining to the offering of the securities covered by the Registration Statement.

     4. To such counsel’s knowledge, there are no legal or governmental proceedings pending to which the Parent Guarantor or any of its subsidiaries is a party or of which any property of the Parent Guarantor or any of its subsidiaries is the subject that are of a character required to be described in the Registration Statement or the Pricing Disclosure Package that are not described as required.

     5. When the Securities have been authenticated in the manner set forth in the Indenture and delivered against due payment therefor, the Securities and the Guarantee will constitute a valid and legally binding obligations of the Company and the Parent Guarantor, respectively, enforceable against the Company and the Parent Guarantor in accordance with their terms, except as that enforcement is subject to (i) any applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or conveyance or other laws relating to or

affecting creditors’ rights generally, (ii) general principles of equity (regardless of whether that enforceability is considered in a proceeding in equity or at law) and (iii) any implied covenants of good faith and fair dealing. The Securities and the Guarantee, in the forms certified by the Company as of the date of such opinion, and the Indenture conform in all material respects to the descriptions thereof contained in the final term sheet prepared and filed pursuant to Section 5(a) of this Agreement and in the information set forth under the captions “Description of Debt Securities” and “Description of the Notes” in the Pricing Prospectus.
