(1) Pursuant to Rule 416 under the Securities Act of 1933, as amended (the “Securities Act”), the number of ordinary shares, par value $0.00001 per share (the “Ordinary Shares”), being registered on behalf of the selling shareholders shall be adjusted to include any additional Ordinary Shares that may become issuable as a result of any share capitalization, sub-division, combination or similar transaction.

(2) Represents (i) Ordinary Shares issued pursuant to the Plan (as defined herein) and registered for resale hereby, (ii) Ordinary Shares issuable from time to time upon the exercise of outstanding Warrants (as defined herein) issued pursuant to the Plan and (iii) Ordinary Shares issued pursuant to the Merger Agreement (as defined herein) and registered for resale hereby. The registrant is also registering an indeterminate number of Ordinary Shares that may become issuable upon exercise of the Warrants pursuant to anti-dilution adjustments of such Warrants.

(3) The proposed maximum offering price per Ordinary Share will be determined from time to time by the selling shareholders in connection with, and at the time of, the sale by the selling shareholders of the Ordinary Shares registered hereunder.

(4) Estimated solely for the purpose of calculating the registration fee pursuant to Rule 457(c) under the Securities Act based on the average of the high and low prices of the Ordinary Shares as reported on the New York Stock Exchange on June 10, 2021.

(5) Of this amount, $57,775.67 has previously been paid in connection with the prior filing of this Registration Statement. With respect to the remaining $45,686.77 of the registration fee, a registration fee of $97,350 was paid in connection with the Post-Effective Amendment No. 1 to the Registration Statement on Form S-3 (File No. 333-228167) of Noble Corporation plc (the Exchange Act predecessor to the registrant), as filed with the Securities and Exchange Commission on February 20, 2020, to register $750,000,000 of various securities (the “Prior Registration Statement”). The Prior Registration Statement was subsequently withdrawn on November 24, 2020, and all of the securities offered thereunder remain unsold. Pursuant to Rule 457(p) of the Securities Act, $39,574.33 of the registration fee paid under the Prior Registration Statement will be used to offset against a portion of the remaining amount of the registration fee due for this Registration Statement. Accordingly, a registration fee of $6,112.44 is being paid with this Registration Statement.

The registrant hereby amends this Registration Statement on such date or dates as may be necessary to delay its effective date until the registrant shall file a further amendment which specifically states that this Registration Statement shall thereafter become effective in accordance with Section 8(a) of the Securities Act of 1933, as amended, or until the Registration Statement shall become effective on such date as the Securities and Exchange Commission, acting pursuant to said Section 8(a), may determine.

The information in this prospectus is not complete and may be changed. These securities may not be sold until the registration statement filed with the Securities and Exchange Commission is effective. This prospectus is not an offer to sell these securities and it is not soliciting an offer to buy these securities in any state where the offer or sale is not permitted.

EXPLANATORY NOTE

This Pre-Effective Amendment No. 1 to Form S-1 on Form S-3 is being filed by Noble Corporation, an exempted company incorporated in the Cayman Islands with limited liability (“Noble”), to convert the Registration Statement on Form S-1 (File No. 333-255406) filed by Noble with the Securities and Exchange Commission (the “SEC”) on April 21, 2021 (the “Form S-1”) into a Registration Statement on Form S-3 and contains an updated prospectus relating to the offering and sale of the Ordinary Shares being registered for resale on the Form S-1.    

As previously reported, on July 31, 2020 (the “Petition Date”), Noble Holding Corporation plc (formerly known as Noble Corporation plc), a public limited company incorporated under the laws of England and Wales (“Legacy Noble”), and certain of its subsidiaries filed voluntary petitions in the United States Bankruptcy Court for the Southern District of Texas (the “Bankruptcy Court”) seeking relief under chapter 11 of title 11 of the United States Code. On September 4, 2020, the Debtors (as defined herein) filed with the Bankruptcy Court the Joint Plan of Reorganization of Noble Corporation plc and its Debtor Affiliates, which was subsequently amended on October 8, 2020 and October 13, 2020 and modified on November 18, 2020 (as amended, modified or supplemented, the “Plan”), and the related disclosure statement. On September 24, 2020, six additional subsidiaries of Legacy Noble (together with Legacy Noble and its subsidiaries that filed on the Petition Date, as the context requires, the “Debtors”) filed voluntary petitions in the Bankruptcy Court. The chapter 11 proceedings were jointly administered under the caption Noble Corporation plc, et al. (Case No. 20-33826) (the “Chapter 11 Cases”). On November 20, 2020, the Bankruptcy Court entered an order confirming the Plan.

In connection with the Chapter 11 Cases and the Plan, on and prior to the Effective Date (as defined herein), Legacy Noble and certain of its subsidiaries effectuated certain restructuring transactions, pursuant to which Legacy Noble formed Noble as an indirect, wholly-owned subsidiary of Legacy Noble and transferred to Noble substantially all of the subsidiaries and other assets of Legacy Noble. On February 5, 2021 (the “Effective Date”), the Plan became effective in accordance with its terms, the Debtors emerged from the Chapter 11 Cases and Noble became the new parent company. See Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Chapter 11 Proceedings and Going Concern” in the 2020 Form 10-K (as defined herein) for a description of the events that occurred on the Effective Date, including the issuance of the Ordinary Shares and the Warrants. In accordance with the Plan, Legacy Noble and its remaining subsidiary will in due course be wound down and dissolved in accordance with applicable law. Noble’s principal asset is all of the shares of Noble Finance Company (formerly known as Noble Corporation), an exempted company incorporated in the Cayman Islands with limited liability (“Finco”). The Bankruptcy Court closed the Chapter 11 Cases with respect to all Debtors other than Legacy Noble, pending its wind down. Finco has no public equity outstanding. The consolidated financial statements of Noble include the accounts of Finco and Noble conducts substantially all of its business through Finco and its subsidiaries. Finco was an indirect, wholly-owned subsidiary of Legacy Noble prior to the Effective Date and has been a direct, wholly-owned subsidiary of Noble since the Effective Date.

On the Effective Date, Noble entered into a registration rights agreement (the “Bankruptcy RRA”) with certain parties who received Ordinary Shares and Warrants under the Plan (the “Bankruptcy RRA Holders”). Under the Bankruptcy RRA, Bankruptcy RRA Holders have certain demand and piggyback registration rights, subject to the limitations set forth in the Bankruptcy RRA. Pursuant to their underwritten offering registration rights, Bankruptcy RRA Holders have the right to demand that Noble register underwritten offerings of any or all of their Registrable Securities (as defined in the Bankruptcy RRA) pursuant to an effective registration statement, subject to certain conditions, including that the aggregate proceeds expected to be received from such an offering is equal to or greater than $20 million, unless such demand is not pursuant to a shelf registration statement, in which case certain Bankruptcy RRA Holders may require that Noble register an underwritten offering for an amount that would enable all remaining Registrable Securities to be included in such offering. In addition, the Bankruptcy RRA requires Noble to register for resale such Registrable Securities pursuant to Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”), including by filing a registration statement on Form S-1 or Form S-3 by the applicable deadline set forth in the Bankruptcy RRA.

i

On March 25, 2021, Noble entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Duke Merger Sub, LLC, a wholly-owned subsidiary of Noble (“Merger Sub”), and Pacific Drilling Company LLC (“Pacific Drilling”), providing for the merger of Merger Sub with and into Pacific Drilling (the “Merger”), with Pacific Drilling continuing as the surviving company and a wholly-owned subsidiary of Noble. The board of directors of Noble (the “Board”) and the board of directors of Pacific Drilling unanimously approved and adopted the Merger Agreement. On April 15, 2021, Noble completed the Merger with Pacific Drilling. On April 15, 2021, in connection with the closing of the Merger, Noble entered into a registration rights agreement (the “Merger RRA”) with each of the holders identified therein (the “Merger RRA Holders”), pursuant to which, among other things, Noble is required to file with the SEC a registration statement registering for resale the Ordinary Shares issuable to the Merger RRA Holders upon consummation of the Merger, and subject to certain limitations set forth therein, certain Merger RRA Holders have customary shelf, demand and piggyback registration rights. In addition, pursuant to the Merger RRA, certain Merger RRA Holders have the right to require Noble, subject to certain limitations set forth therein, to effect a distribution of any or all of their Ordinary Shares by means of an underwritten offering. Noble is not obligated to effect any underwritten offering unless the dollar amount of the registrable securities of the Merger RRA Holder(s) demanding such underwritten offering to be included therein is reasonably likely to result in gross sale proceeds of at least $20 million.

Noble is filing the registration statement of which this prospectus forms a part pursuant to the foregoing registration obligations under the Bankruptcy RRA and the Merger RRA. The foregoing description of each of the Bankruptcy RRA and the Merger RRA is only a summary and does not purport to be complete, and such description is qualified in its entirety by reference to the full text of the Bankruptcy RRA and the Merger RRA, as applicable, each of which is filed as an exhibit to the registration statement of which this prospectus forms a part.

Unless otherwise expressly set forth or as the context otherwise indicates, all financial information and data and accompanying financial statements and corresponding notes, as of and prior to the Effective Date, contained or incorporated by reference herein reflect the actual historical consolidated results of operations and financial condition of Legacy Noble for the periods presented and do not give effect to the Plan or any of the transactions contemplated thereby or the adoption of fresh start accounting, which Noble adopted as of the Effective Date. Accordingly, such financial information may not be representative of Noble’s performance or financial condition after the Effective Date. Except with respect to such historical financial information and data and accompanying financial statements and corresponding notes or as otherwise suggested by the context, all other information contained herein relates to Noble following the Effective Date.

This prospectus is part of a registration statement that we have filed with the SEC. This prospectus provides you with a general description of us and the securities that may be offered by the selling shareholders. Because each of the selling shareholders may be deemed to be an “underwriter” within the meaning of the Securities Act, each time securities are offered by the selling shareholders pursuant to this prospectus, the selling shareholders may be required to provide you with this prospectus and, in certain cases, a prospectus supplement that will contain specific information about the selling shareholders and the terms of the securities being offered. The prospectus supplement may also add to, update or change the information contained in this prospectus.

We and the selling shareholders take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. We are not, and the selling shareholders are not, making any offer to sell the Ordinary Shares in any jurisdiction where the offer is not permitted. The information contained or incorporated by reference in this prospectus is accurate only as of the date on the cover of this prospectus or, in the case of information incorporated by reference, only as of the date of such information, regardless of the time of delivery of this prospectus or of any sale of the Ordinary Shares. Our business, financial condition, results of operations and prospects may have changed since such dates.

We have not, and the selling shareholders have not, taken any action to permit this offering or the possession or distribution of this prospectus in any jurisdiction where action for that purpose is required, other than in the United States. Persons outside the United States who come into possession of this prospectus must inform themselves about, and observe any restrictions relating to, the offer and sale of the Ordinary Shares and the distribution of this prospectus outside the United States.

This prospectus contains forward-looking statements that are subject to a number of risks and uncertainties, many of which are beyond our control. See “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements.”

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL INFORMATION

The following unaudited pro forma condensed consolidated financial information (the “Pro Forma Financial Information”) of Noble gives effect to the Plan, including the financing transactions contemplated thereunder. The Pro Forma Financial Information presents the financial information of Noble assuming the Plan’s Effective Date had occurred on January 1, 2020 for the unaudited pro forma condensed consolidated statements of operations.

The Pro Forma Financial Information presented herein is provided for informational and illustrative purposes only and is not necessarily indicative of the financial results that would have been achieved had the events and transactions occurred on the dates assumed, nor is such financial data necessarily indicative of the results of operations in future periods. Adjustments are based on available information and certain assumptions that the Company believes are reasonable and supportable. The Pro Forma Financial Information should be read in conjunction with Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the consolidated financial statements and notes included in the 2020 Form 10-K.

The Pro Forma Financial Information is not intended to represent Noble’s actual post-Effective Date results of operations, and any differences to actual results could be material.

Noble’s historical financial statements will not be comparable to Noble’s financial statements after emergence from Chapter 11 due to the effects of the Plan and the adoption and application of Financial Accounting Standards Board Accounting Standards Codification (“ASC”) Topic 852, Reorganizations (“ASC Topic 852”) under accounting principles generally accepted in the United States of America (“GAAP”). The Pro Forma Financial Information has been prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses.”

Reorganization Adjustments

The Reorganization Adjustments column of the Pro Forma Financial Information gives effect to the consummation of the Plan, including the following transactions:

• Legacy Noble’s previously outstanding ordinary shares and equity-based awards were cancelled, extinguished and discharged against the issue of the Tranche 3 Warrants (as defined herein);

• all amounts outstanding under the 2017 Credit Facility (as defined in the 2020 Form 10-K), including the interest, were paid in full;

• all of our then outstanding senior notes were settled for the Ordinary Shares, Tranche 1 Warrants and Tranche 2 Warrants;

• the issuance of 50 million Ordinary Shares;

• professional services fees incurred after December 31, 2020 through the Effective Date; and

• the issuance of $216 million of senior secured second lien notes (the “Notes”) and our entry into the new $675 million senior secured revolving credit facility (with a $67.5 million sublimit for the issuance of letters of credit thereunder) (the “Revolving Credit Facility”) with initial borrowings of $177.5 million.

Fresh Start Adjustments

We adopted fresh start accounting in accordance with ASC Topic 852 as of the Effective Date of our emergence from reorganization under Chapter 11, resulting in reorganized Noble becoming the successor (solely for purposes of the Pro Forma Financial Information, the “Successor”) for financial reporting purposes. In accordance with ASC Topic 852, with the application of fresh start accounting, the Company allocated its

8

reorganization value to its individual assets based on their estimated fair values in conformity with ASC Topic 805, “Business Combinations.” Liabilities subject to compromise of the predecessor entity (solely for purposes of the Pro Forma Financial Information, the “Predecessor”) were either reinstated or extinguished as part of the reorganization.

The Successor enterprise value of the reorganized Company, as approved by the Bankruptcy Court in support of the Plan, was estimated to be $1.3 billion, which represented the mid-point of a determined range. A pro forma reorganization value of approximately $1.8 billion was then determined by adding non-interest bearing liabilities and cash adjustments to the $1.3 billion enterprise value. The Company’s enterprise value was determined with the assistance of a third-party valuation expert who used available comparable market data and quotations, discounted cash flow analysis and other internal financial information and projections. Our estimates of fair value are inherently subject to significant uncertainties and contingencies beyond our control. Accordingly, there can be no assurance that the estimates, assumptions, valuations, appraisals and financial projections will be realized, and actual results could vary materially. Moreover, the value of Noble’s shares subsequent to the Effective Date may differ materially from the equity presented for accounting purposes under GAAP.

(Unless otherwise indicated, dollar amounts are in thousands)

Note 1. Basis of Presentation

The accompanying unaudited pro forma condensed consolidated statements of operations and explanatory notes present the Pro Forma Financial Information of Noble assuming the consummation of the Plan had occurred on January 1, 2020.

The following are descriptions of the columns included in the accompanying Pro Forma Financial Statements:

• Historical—Represents the historical condensed consolidated statement of operations of the predecessor entity of Noble for the period ended December 31, 2020.

• Predecessor Historical—Represents the historical condensed consolidated statement of operations for the predecessor entity of Noble for the period from January 1, 2021 through the Effective Date of the Plan of February 5, 2021.

• Successor Historical—Represents the historical condensed consolidated statement of operations for the successor entity of Noble for the period of February 6, 2021 through March 31, 2021.

• Reorganization and Fresh Start Adjustments—Represents reorganization adjustments as of and for the year ended December 31, 2020 and for the three months ended March 31, 2021, assuming the Effective Date of the Plan had occurred on January 1, 2020 for the unaudited condensed consolidated statements of operations, and for the adoption of fresh start accounting.

• Removal of Reorganization Items, net—These are non-recurring expenses, gains and losses that are realized or incurred as a direct result of the Chapter 11 Cases recorded under “Reorganization items, net.” Such amounts relate to Noble’s Predecessor period and have been removed for a fair presentation of the pro forma statement of operations.

Note 2. Pro Forma Adjustments

Pro Forma Adjustments to the Unaudited Pro Forma Condensed Consolidated Statement of Operations, Twelve Months Ended December 31, 2020

Reorganization Adjustments

(a) Stock based compensation

Reflects an increase in stock-based compensation expense based on the new awards issued.

(b) Interest Expense

The adjustment reflects change of interest expense as a result of the Plan. The Plan provides for the repayment and settlement of Predecessor’s 2017 Credit Facility and senior notes, respectively. Upon emergence, we entered into the Revolving Credit Facility and issued Notes with interest rate of LIBOR + 4.75% and 15% payable semi-annually by paid in kind notes, respectively. The pro forma adjustments to interest expense was calculated as follows:

Reversal of Predecessor interest expense including amortization of deferred financing costs	$	(162,156	)
Pro forma interest on the Successor Revolving Credit Facility and Notes		45,286
Amortization of Successor deferred financing costs		2,889
Pro forma adjustment for interest expense	$	(113,981	)

12

Assuming an increase in interest rates on the Revolving Credit Facility and the Notes of 1/8%, pro forma interest would increase by $0.5 million.

(c) Reorganization Items, net

The adjustment represents the estimated remaining costs that were directly attributable to the Chapter 11 reorganization including the following:

Professional fees	$	(15,017	)
Acceleration of unrecognized Predecessor share-based compensation		(18,546	)
Gain on settlement of liabilities subject to compromise		2,609,060
Pro forma adjustment to reorganization items, net	$	2,575,497

(d) Includes $600 thousand related to the rejection of an executory contract per the Plan.

Fresh Start Adjustments

(e) Revenue

Adjustment reflects the amortization of favorable contracts with customers as a result of adopting fresh start accounting. The remaining useful life of the favorable contracts range between 1-3 years.

(f) Depreciation and amortization

Reflects the pro forma decrease in depreciation expense based on new asset values as a result of adopting fresh start accounting. The pro forma adjustment to depreciation expense was calculated as follows:

Removal of Predecessor depreciation expense	$	(374,129	)
Pro forma depreciation expense		94,968
Pro forma adjustment for depreciation and amortization	$	(279,161	)

Drilling equipment and facilities are depreciated using the straight-line method over their estimated useful lives as of the date placed in service or date of major refurbishment. Estimated useful lives of our drilling equipment range from three to thirty years. Other property and equipment is depreciated using the straight-line method over useful lives ranging from two to forty years.

(g) Income tax benefit (provision)

Reflects the pro forma adjustment to tax expense as a result of reorganization adjustments and adopting fresh start accounting. The income tax impact was calculated by applying the appropriate statutory tax rate of the respective tax jurisdictions to which the pro forma adjustments relate and which are reasonably expected to occur.

(h) Impact of Fresh Start Accounting

Reflects the cumulative impact of fresh start accounting adjustments, excluding tax impacts.

SELLING SHAREHOLDERS

This prospectus relates to the resale, from time to time, by the selling shareholders included in the table below, which we refer to collectively as the selling shareholders, of up to 37,812,067 Ordinary Shares, including up to 2,541,708 Ordinary Shares issuable upon the exercise of the Warrants. The Tranche 1 Warrants and the Tranche 2 Warrants are exercisable at the option of the holder thereof until February 4, 2028. The Penny Warrants have no stated expiration date; however, the Penny Warrants will expire 30 days after the consummation of a Fundamental Transaction (as defined in the Penny Warrant Agreement) to the extent any Penny Warrants then remain outstanding. This prospectus also relates to an indeterminate number of Ordinary Shares that may become issuable upon exercise of the Warrants as a result of anti-dilution adjustments. The Ordinary Shares are being registered pursuant to registration rights granted to the selling shareholders under the Bankruptcy RRA and the Merger RRA.

The information provided below with respect to the selling shareholders has been furnished to us by or on behalf of the selling shareholders and is current as of May 31, 2021, unless otherwise indicated below.

The selling shareholders may offer any or all of their Ordinary Shares for resale from time to time pursuant to this prospectus. However, the selling shareholders are under no obligation to sell any of the Ordinary Shares offered pursuant to this prospectus. Because the selling shareholders may sell none, all or some of the Ordinary Shares owned by them, we cannot estimate the number or percentage of Ordinary Shares that will be beneficially owned by the selling shareholders after this offering and have therefore made certain assumptions with respect thereto as indicated in the table below. In addition, the selling shareholders may sell, transfer or otherwise dispose of, at any time or from time to time since the date on which the selling shareholders provided the information regarding the Ordinary Shares owned by them, all or some of the Ordinary Shares owned by them in transactions exempt from the registration requirements of the Securities Act.

To our knowledge, none of the selling shareholders has, or has had within the past three years, any position, office or other material relationship with us or any of our predecessors or affiliates, other than their ownership of the Ordinary Shares, except in connection with (i) the Bankruptcy RRA, (ii) the Plan, (iii) a Restructuring Support Agreement, dated July 31, 2020 (as amended by the First Amendment thereto, dated August 20, 2020), among the Debtors and certain noteholders of Legacy Noble, (iv) a Backstop Commitment Agreement, dated October 12, 2020 (the “Backstop Commitment Agreement”), among the Debtors and the backstop parties thereto (collectively, the “Backstop Parties”), pursuant to which Noble and Finco consummated on the Effective Date a rights offering of Notes and associated Ordinary Shares at an aggregate subscription price of $200 million, (v) the Relationship Agreement described below, (vi) the Board Observer Agreement described below, (vii) the director designation right described under “Description of Capital Stock—Director Designation Right,” (viii) the Merger RRA, (ix) the Merger Agreement and (x) the Voting Agreements described below.

Pursuant to the Plan, on the Effective Date, Noble, certain funds and accounts (the “Investors”) for which Pacific Investment Management Company LLC (the “Investor Manager”) serves as investment manager, adviser or sub-adviser, as applicable, and certain of the former holders (or investment advisors or managers to such holders) of certain series of Legacy Noble’s then outstanding senior notes entered into a Relationship Agreement (the “Relationship Agreement”), pursuant to which, among other things, Noble agreed that until the earlier of such time as the Investors cease to hold in the aggregate 35% or more of the Outstanding Ordinary Shares (as defined in the Relationship Agreement) and the fourth anniversary of the Effective Date, Noble will not remove its Chief Executive Officer or appoint a replacement Chief Executive Officer unless it obtains the prior written consent of the Investors by the Investor Manager acting on their behalf (such consent not to be unreasonably withheld, conditioned or delayed).

Also on the Effective Date, Noble and the Investor Manager entered into a Board Observer Agreement (the “Board Observer Agreement”), pursuant to which, among other things, Noble agreed that until such time as the Investors cease to hold in the aggregate 20% or more of the outstanding Ordinary Shares, the Investor Manager will have the right to designate an individual to attend meetings of the Board and of committees of the Board, subject to customary exceptions and conditions. The Investor Manager has designated a board observer pursuant to the Board Observer Agreement.

15

Concurrently with the entry into the Merger Agreement, Noble and certain equity holders of Pacific Drilling (each, a “Member” and, collectively, the “Members”), which collectively represented approximately 66% of the issued and outstanding Membership Interests and 64% of the Pacific Warrants, entered into voting and support agreements (collectively, the “Voting Agreements”) in connection with the Merger Agreement. Among other things, each Voting Agreement required that each Member that was party to such Voting Agreement (a) vote (or cause to be voted) its Membership Interests (i) in favor of the approval and adoption of the Merger, the Merger Agreement and all other transactions contemplated by the Merger Agreement, (ii) among other things, against any merger agreement or merger (other than the Merger Agreement, the Merger and the transactions contemplated thereby), any action or any other takeover proposal relating to Pacific Drilling, (b) be bound by certain other covenants and agreements relating to the Merger, including the delivery of any notices and documentation required to effect a “Drag-Along Sale” as defined in the Pacific Drilling limited liability company agreement, and (c) be bound by certain transfer restrictions with respect to such securities subject to certain exceptions. The Voting Agreements terminated at the effective time of the Merger.

DESCRIPTION OF CAPITAL STOCK

The following is a description of our capital stock and related provisions of Noble’s Amended and Restated Articles of Association (the “Articles”) and Amended and Restated Memorandum of Association (the “Memorandum”), the Emergence Warrant Agreements (as defined herein) and the Penny Warrant Agreement. This description is only a summary and does not purport to be complete and is qualified in its entirety by reference to, and should be read in conjunction with, the full text of the Articles, the Memorandum, the Emergence Warrant Agreements and the Penny Warrant Agreement, each of which is filed as an exhibit to the registration statement of which this prospectus forms a part, and the applicable provisions of Cayman Islands law. In the following description, a “shareholder” is a holder of Ordinary Shares.

As of June 7, 2021, there were 60,137,878 Ordinary Shares outstanding and 6,463,182 Penny Warrants issued and outstanding. In addition, as of June 7, 2021, 8,332,910 Tranche 1 Warrants, 8,332,602 Tranche 2 Warrants and 2,777,698 Tranche 3 Warrants were outstanding and exercisable.

Ordinary Shares

Authorized Share Capital

Pursuant to the Memorandum, the share capital of Noble is $6,000 divided into 500,000,000 ordinary shares of a par value of $0.00001 each and 100,000,000 shares of a par value of $0.00001 each, each of such class or classes having the rights as the Board may determine from time to time.

Voting

The holders of Ordinary Shares will be entitled to one vote per share. The Articles do not provide for cumulative voting.

There are no limitations imposed by Cayman Islands law or the Articles on the right of nonresident shareholders to hold or vote their Ordinary Shares.

All or any of the rights attached to any class of shares (unless otherwise provided by the terms of issue of the shares of that class) may be varied only with the consent in writing of the holders of not less than two thirds of the issued shares of that class, or with the approval of a resolution passed by a majority of not less than two thirds of the votes cast at a separate meeting of the holders of the shares of that class.

Under Cayman Islands law, some matters, like altering the Memorandum or the Articles, changing the name of Noble, voluntarily winding up Noble or resolving to be registered by way of continuation in a jurisdiction outside the Cayman Islands, require the approval of shareholders by a special resolution. A special resolution is a resolution passed by the holders of at least two thirds of the shares voted at a general meeting or approved in writing by all shareholders of Noble entitled to vote at a general meeting of Noble.

Quorum for General Meetings

The presence of shareholders who, present in person (which, in the case of a corporate shareholder shall include being present by a representative) or by proxy, together represent at least the majority of the total voting rights of all the shareholders entitled to vote in relation to the meeting. The matters set forth below require the presence of at least two thirds of the total voting rights of all the shareholders entitled to vote in relation to the meeting:

• the adoption by Noble of a resolution to remove a director; or

• the adoption by Noble of a resolution to amend, vary, suspend the operation of, disapply or cancel:

24

• Articles 21.1, 21.2 and 21.11, which relate to the convening of, and proceedings and procedures at, general meetings;

• Article 26, which relates to the number and qualifications of the directors of Noble;

• Article 28, which relates to the appointment and removal of directors of Noble;

• Article 29, which relates to vacancies on the Board; or

• Article 48, which relates to transactions with Interested Shareholders (as defined in the Articles).

The shareholders present at a duly constituted general meeting may continue to transact business until adjournment, despite the withdrawal of shareholders that leaves less than a quorum.

Dividend Rights

Subject to any rights and restrictions of any other class or series of shares, the Board may, from time to time, declare dividends on the shares issued and authorize payment of the dividends out of Noble’s lawfully available funds. The Board may declare that any dividend be paid wholly or partly by the distribution of shares of Noble or specific assets.

Although Noble does not expect to pay periodic cash dividends on Ordinary Shares in the foreseeable future, any future declaration and payment of dividends by Noble would be:

• dependent upon its results of operations, financial condition, cash requirements and other relevant factors;

• subject to the discretion of the Board;

• subject to restrictions contained in debt instruments; and

• payable only out of its accumulated profits or its share premium account in accordance with Cayman Islands law.

The share premium account is the excess of the purchase price for shares issued over the nominal or par value of those shares.

Rights Upon Liquidation

Upon the liquidation of Noble, after creditors of Noble have been paid in full and the full amounts that holders of any issued shares ranking senior to the Ordinary Shares as to distribution on liquidation or winding up are entitled to receive have been paid or set aside for payment, the holders of Ordinary Shares are entitled to receive, pro rata, any remaining assets of Noble available for distribution. The liquidator may deduct from the amount payable in respect of those Ordinary Shares any liabilities the holder has to or with Noble.

No Sinking Fund

The Ordinary Shares have no sinking fund provisions.

No Liability for Further Calls or Assessments

The Ordinary Shares are duly and validly issued, fully paid and nonassessable.

No Preemptive Rights

Holders of Ordinary Shares will have no preemptive or preferential right to purchase any securities of Noble.

25

Redemption and Conversion

The Ordinary Shares will not be convertible into shares of any other class or series or be subject to redemption either by Noble or the holder of the shares unless the manner of redemption has been determined, by a special resolution of the shareholders, before the issue of such Ordinary Shares.

Repurchase

Under the Articles, Noble may purchase any issued Ordinary Shares in the circumstances and on the terms as are agreed by Noble and the holder of the shares whether or not Noble has made a similar offer to all or any other of the holders of Ordinary Shares.

Restrictions on Transfer

Subject to the rules of the New York Stock Exchange and any other stock exchange on which the Ordinary Shares may be listed, the Board may, in its absolute discretion and without assigning any reason, decline to register any transfer of shares.

Other Classes or Series of Shares

The Board may from time to time authorize by means of a board resolution the issuance of preferred shares in one or more series of preferred shares, and in the resolution or resolutions providing for the issue of such shares, the Board is expressly authorized to fix for each such series the number of shares which shall constitute such series, voting power, full or limited, or no voting power, and designations, preferences and relative, participating, optional or other special rights and qualifications, limitations or restrictions thereof. Such a “blank check” preferred share provision could have certain “anti-takeover” effects. See “—Anti-Takeover Provisions.”

Compulsory Acquisition of Shares Held by Minority Holders

An acquiring party is generally able to acquire compulsorily the Ordinary Shares of minority holders in one of two ways:

• By a procedure under the Cayman Islands Companies Act (the “Companies Act”), known as a “scheme of arrangement.” A scheme of arrangement is made by obtaining the consent of the Cayman Islands company, the consent of the court and approval of the arrangement by holders of Ordinary Shares (1) representing a majority in number of the shareholders present at the meeting held to consider the arrangement and (2) holding at least 75% of all the issued Ordinary Shares other than those held by the acquiring party, if any. If a scheme of arrangement receives all necessary consents and approvals, all holders of ordinary shares of a company would be compelled to sell their shares under the terms of the scheme of arrangement.

• By acquiring pursuant to a tender offer 90% of the Ordinary Shares not already owned by the acquiring party (the “offeror”). If an offeror has, within four months after the making of an offer for all the Ordinary Shares not owned by the offeror, obtained the approval of not less than 90% of all the shares to which the offer relates, the offeror may, at any time within two months after the end of that four-month period, require any nontendering shareholder to transfer its shares on the same terms as the original offer. In those circumstances, nontendering shareholders will be compelled to sell their shares, unless within one month from the date on which the notice to compulsorily acquire was given to the nontendering shareholder, the nontendering shareholder is able to convince the court to order otherwise. The Companies Act also provides that a resolution of shareholders shall not be required in circumstances where a parent company seeks to merge with a subsidiary company (that is, a company in which it owns 90% of the issued and outstanding shares). In that event, providing that the remaining requirements for a merger have been met, once the offeror has acquired 90% of the target it will be able effectively to “squeeze out” the remaining minority shareholders without having to wait out the aforementioned four-month period.

26

Registration Rights

Bankruptcy Registration Rights Agreement

On the Effective Date, Noble entered into the Bankruptcy RRA with the Bankruptcy RRA Holders. Under the Bankruptcy RRA, Bankruptcy RRA Holders have certain demand and piggyback registration rights, subject to the limitations set forth in the Bankruptcy RRA. Pursuant to their underwritten offering registration rights, Bankruptcy RRA Holders have the right to demand that Noble register underwritten offerings of any or all of their Registrable Securities (as defined in the Bankruptcy RRA) pursuant to an effective registration statement, subject to certain conditions, including that the aggregate proceeds expected to be received from such an offering is equal to or greater than $20 million, unless such demand is not pursuant to a shelf registration statement, in which case certain Bankruptcy RRA Holders may require that Noble register an underwritten offering for an amount that would enable all remaining Registrable Securities to be included in such offering. In addition, the Bankruptcy RRA requires Noble to register for resale such Registrable Securities pursuant to Rule 415 under the Securities Act, including by filing a registration statement on Form S-1 or Form S-3 by the applicable deadline set forth in the Bankruptcy RRA.

Merger Registration Rights Agreement

On April 15, 2021, in connection with the closing of the Merger, Noble entered into the Merger RRA with the Merger RRA Holders, pursuant to which, among other things, Noble is required to file with the SEC a registration statement registering for resale the Ordinary Shares issuable to the Merger RRA Holders upon consummation of the Merger, and subject to certain limitations set forth therein, certain Merger RRA Holders have customary shelf, demand and piggyback registration rights. In addition, pursuant to the Merger RRA, certain Merger RRA Holders have the right to require Noble, subject to certain limitations set forth therein, to effect a distribution of any or all of their Ordinary Shares by means of an underwritten offering. Noble is not obligated to effect any underwritten offering unless the dollar amount of the registrable securities of the Merger RRA Holder(s) demanding such underwritten offering to be included therein is reasonably likely to result in gross sale proceeds of at least $20 million.

Transfer Agent

The transfer agent and registrar for the Ordinary Shares is Computershare Inc., a Delaware corporation (“Computershare”).

Listing

Our Ordinary Shares are listed on the New York Stock Exchange under the symbol “NE.”

Anti-Takeover Provisions

General

The Articles have provisions that could have an anti-takeover effect. These provisions are intended to enhance the ability of the Board to deal with unsolicited takeover attempts by increasing the likelihood of continuity and stability in the composition of the Board. These provisions could have the effect of discouraging transactions that may involve an actual or threatened change of control of Noble.

Number of Directors

The Articles provide that the Board will consist of not less than three directors nor more than nine directors, the exact number to be set from time to time by an ordinary resolution. An ordinary resolution is a resolution passed by the holders of more than 50% of the shares voted at a general meeting or approved in writing by all shareholders of Noble entitled to vote at a general meeting of Noble.

27

Advance Notice Provisions

The Articles establish an advance notice procedure that must be followed by shareholders if they wish to nominate candidates for election as directors at an annual general meeting of shareholders. The Articles provide generally that, if a shareholder desires to nominate a candidate for election as a director at an annual general meeting, then such shareholder must give us notice not less than 90 days nor more than 120 days prior to the first anniversary of the preceding year’s annual general meeting. The notice must contain specified information concerning the shareholder submitting the proposal. These procedures do not apply to the Investor Director (as defined herein).

Action Only by Unanimous Written Consent

Subject to the terms of any other class of shares in issue, any action required or permitted to be taken by the holders of Ordinary Shares must be taken at a duly called annual or extraordinary general meeting of shareholders or by written resolution signed by all of the holders of Ordinary Shares. Extraordinary general meetings may be called by a majority of the entire Board, the Chairman of the Board, the Chief Executive Officer or by shareholders holding at least 30% of paid up voting share capital of Noble.

Preferred Shares

The Board is authorized, without obtaining any vote or consent of the holders of any class or series of shares, unless expressly provided by the terms of issue of a class or series, to issue from time to time any other classes or series of shares with the designations and relative powers, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or terms or conditions of redemption as they consider fit. The Board could authorize the issuance of preferred shares with terms and conditions that could discourage a takeover or other transaction that holders of some or a majority of the Ordinary Shares might believe to be in their best interests or in which holders might receive a premium for their shares over the then market price of the shares. No preferred shares have been established as of the date of this prospectus.

Quorum Requirements

The special quorum provisions contained in the Articles require the presence of shareholders who, present in person (which, in the case of a corporate shareholder shall include being present by a representative) or by proxy, together represent at least the majority of the total voting rights of all the shareholders entitled to vote in relation to the meeting. The matters set forth below require the presence of at least two thirds of the total voting rights of all the shareholders entitled to vote in relation to the meeting:

• the adoption by Noble of a resolution to remove a director; or

• the adoption by Noble of a resolution to amend, vary, suspend the operation of, disapply or cancel:

• Articles 21.1, 21.2 and 21.11, which relate to the convening of, and proceedings and procedures at, general meetings;

• Article 26, which relates to the number and qualifications of the directors of Noble;

• Article 28, which relates to the appointment and removal of directors of Noble;

• Article 29, which relates to vacancies on the Board; or

• Article 48, which relates to transactions with Interested Shareholders (as defined in the Articles).

Restrictions on Business Combinations

As a Cayman Islands company, Noble is not subject to Section 203 of the Delaware General Corporation Law, which restricts business combinations with interested shareholders. However, Article 48 of the Articles

28

contains provisions that largely mirror the intention of Section 203 and generally restrict “business combinations” between Noble and an “interested shareholder.” Specifically, “business combinations” between an “interested shareholder” and Noble are prohibited for a period of three years after the time the interested shareholder acquired its shares, unless:

• the business combination or the transaction resulting in the person becoming an interested shareholder is approved by the Board prior to the date the interested shareholder acquired Noble’s shares;

• the interested shareholder acquired at least 85% of Noble’s shares in the transaction in which it became an interested shareholder; or

• the business combination is approved by a majority of the Board and by the affirmative vote of disinterested shareholders holding at least two thirds of the shares generally entitled to vote which are not owned by the interested shareholder.

For purposes of Article 48, “business combinations” is defined broadly to include mergers, consolidations of majority owned subsidiaries, sales or other dispositions of assets having an aggregate value in excess of 10% of the consolidated assets of Noble, and most transactions that would increase the interested shareholder’s proportionate share ownership in Noble. “Interested shareholder” is defined as a person who, together with any affiliates and/or associates of that person, beneficially owns, directly or indirectly, 15% or more of the issued voting shares of Noble.

Notwithstanding the foregoing, Article 48 of the Articles will not apply to a business combination with any interested shareholder that is a “qualifying interested shareholder.” A “qualifying interested shareholder” means any person that becomes an interested shareholder as a result of the issuance of Ordinary Shares, Penny Warrants and Emergence Warrants (as defined herein) to such person or any of its affiliates or associates on the Effective Date pursuant to the Plan (including Ordinary Shares issued pursuant to the Backstop Commitment Agreement); provided that if at any time a qualifying interested shareholder owns, directly or indirectly (together with its associates and affiliates), less than the “specified ownership percentage” of the voting shares of Noble for 365 consecutive days, such person shall cease to be a qualifying interested shareholder on such 365th day. “Specified ownership percentage” means 15% of the combined voting power of the voting shares of Noble; provided that if a qualifying interested shareholder owns, directly or indirectly (together with its associates and affiliates), less than 15% of the combined voting power of the voting shares of Noble as the result of the issuance by Noble of additional voting shares, then, with respect to such qualifying interested shareholder, the specified ownership percentage means 10% of the combined voting power of the voting shares of Noble until such time, if any, as such qualifying interested shareholder owns, directly or indirectly (together with its associates and affiliates), 15% or more of the combined voting power of the voting shares of Noble, in which case the specified ownership percentage with respect to such person shall again mean 15% of the combined voting power of the voting shares of Noble. The acquisition of additional voting shares by any qualifying interested shareholder on or following the Effective Date will not result in such person ceasing to constitute a qualifying interested shareholder.

Director Designation Right

Pursuant to the Articles, subject to certain conditions and limitations, for so long as the Designated Entities (as defined below) hold, in the aggregate, no fewer than 20% of the outstanding and issued Ordinary Shares, the Designated Entities (with such right exercised by their designating party) shall be entitled to nominate, and the Board shall appoint, and remove one director (the “Investor Director”). For so long as the Designated Entities hold, in aggregate, no fewer than 20% of the outstanding and issued Ordinary Shares, the Investor Director may be removed by, and only by, the affirmative vote or written consent of the designating party. If the designating party entitled to designate a person to fill any directorship fails to do so, then such directorship shall remain vacant until filled by such designating party. “Designated Entities” means the funds and accounts for which the same person serves as investment manager, advisor or sub-advisor (as applicable) on the Effective Date and which funds and accounts own, in the aggregate, in excess of 35% of the issued and outstanding Ordinary Shares

29

upon effectiveness of the Plan on the Effective Date. The Investor Manager is currently the designating party for the Designated Entities. The Investor Manager has designated an Investor Director, pursuant to which the Board appointed Paul Aronzon to serve as a director on April 19, 2021.

Emergence Warrants

On the Effective Date and pursuant to the Plan, Noble entered into (i) a Tranche 1 Warrant Agreement (the “Tranche 1 Warrant Agreement”) with Computershare and Computershare Trust Company, N.A., a federally chartered trust company, as warrant agent (together with Computershare, the “Warrant Agent”), which provides for Noble’s issuance of an aggregate of 8,333,081 seven-year warrants with Black Scholes protection (the “Tranche 1 Warrants”) to purchase Ordinary Shares, (ii) a Tranche 2 Warrant Agreement (the “Tranche 2 Warrant Agreement”) with the Warrant Agent, which provides for Noble’s issuance of an aggregate of 8,333,081 seven-year warrants with Black Scholes protection (the “Tranche 2 Warrants”) to purchase Ordinary Shares, and (iii) a Tranche 3 Warrant Agreement (the “Tranche 3 Warrant Agreement” and, collectively with the Tranche 1 Warrant Agreement and the Tranche 2 Warrant Agreement, the “Emergence Warrant Agreements”) with the Warrant Agent, which provides for Noble’s issuance of an aggregate of 2,777,698 five-year warrants with no Black Scholes protection (the “Tranche 3 Warrants” and, collectively with the Tranche 1 Warrants and the Tranche 2 Warrants, the “Emergence Warrants”) to purchase Ordinary Shares. On the Effective Date and pursuant to the Plan, Noble issued 8,333,081 Tranche 1 Warrants and 8,333,081 Tranche 2 Warrants to the holders of certain series of Legacy Noble’s then outstanding senior notes and 2,777,698 Tranche 3 Warrants to the holders of Legacy Noble’s ordinary shares outstanding prior to the Effective Date.

Exercise

The Tranche 1 Warrants are exercisable from the Effective Date until 5:00 p.m., Eastern time, on February 4, 2028, at which time all unexercised Tranche 1 Warrants will expire and the rights of the holders of such Tranche 1 Warrants to purchase Ordinary Shares will terminate. The Tranche 1 Warrants are initially exercisable for one Ordinary Share per Tranche 1 Warrant at an exercise price of $19.27 per Tranche 1 Warrant (as may be adjusted from time to time pursuant to the Tranche 1 Warrant Agreement, the “Tranche 1 Exercise Price”).

The Tranche 2 Warrants are exercisable from the Effective Date until 5:00 p.m., Eastern time, on February 4, 2028, at which time all unexercised Tranche 2 Warrants will expire and the rights of the holders of such Tranche 2 Warrants to purchase Ordinary Shares will terminate. The Tranche 2 Warrants are initially exercisable for one Ordinary Share per Tranche 2 Warrant at an exercise price of $23.13 per Tranche 2 Warrant (as may be adjusted from time to time pursuant to the Tranche 2 Warrant Agreement, the “Tranche 2 Exercise Price”).

The Tranche 3 Warrants are exercisable from the Effective Date until 5:00 p.m., Eastern time, on February 4, 2026, at which time all unexercised Tranche 3 Warrants will expire and the rights of the holders of such Tranche 3 Warrants to purchase Ordinary Shares will terminate. The Tranche 3 Warrants are initially exercisable for one Ordinary Share per Tranche 3 Warrant at an exercise price of $124.40 per Tranche 3 Warrant (as may be adjusted from time to time pursuant to the Tranche 3 Warrant Agreement, the “Tranche 3 Exercise Price” and, each of the Tranche 1 Exercise Price, the Tranche 2 Exercise Price and the Tranche 3 Exercise Price, an “Exercise Price”).

Each of the Emergence Warrants is exercisable by a holder paying the applicable Exercise Price therefor in cash or on a cashless basis, at the election of the holder, upon the terms and subject to the conditions set forth in the applicable Emergence Warrant Agreement.

30

Anti-Dilution Adjustments

The number of Ordinary Shares for which an Emergence Warrant is exercisable, and the applicable Exercise Price therefor, are subject to adjustment from time to time upon the occurrence of certain events, including share sub-division, consolidation, capitalization, certain offers by Noble to repurchase Ordinary Shares, dividends and distributions of cash, other securities or other property and certain rights offerings.

No Rights as Shareholders

Pursuant to the Emergence Warrant Agreements, no holder of Emergence Warrants shall have or exercise any rights held by holders of Ordinary Shares solely by virtue thereof as a holder of Emergence Warrants, including the right to vote and to receive dividends and other distributions as a holder of Ordinary Shares.

Black Scholes Protection for Fundamental Transactions

Each of the Tranche 1 Warrant Agreement and the Tranche 2 Warrant Agreement entitles the holders of Tranche 1 Warrants and Tranche 2 Warrants, respectively, to Black Scholes protection for the value thereof upon the consummation of a Fundamental Transaction (as defined in the Tranche 1 Warrant Agreement or the Tranche 2 Warrant Agreement, as applicable). If (i) Noble consummates a Fundamental Transaction while any of the Tranche 1 Warrants or the Tranche 2 Warrants remain outstanding and (ii) the consideration to which holders of Ordinary Shares are entitled consists in whole or in part of cash, then Noble will pay for each such Emergence Warrant an amount of cash equal to the greater of (A) the product of (1) the number of Ordinary Shares underlying such Emergence Warrant (the “Warrant Share Number”) and (2) the amount, if any, by which (x) such cash consideration exceeds (y) the applicable Exercise Price multiplied by the percentage of the total consideration for the Fundamental Transaction paid or payable in cash (the “Cash Consideration Percentage”), and (B) the value of such Emergence Warrant as determined in accordance with the Tranche 1 Warrant Agreement or the Tranche 2 Warrant Agreement (as applicable) based on Black Scholes option pricing inputs as of the date of the consummation of the Fundamental Transaction (the “Black Scholes Value”) multiplied by the Cash Consideration Percentage. In addition, if (i) Noble consummates a Fundamental Transaction while any of the Tranche 1 Warrants or the Tranche 2 Warrants remain outstanding, (ii) holders of Ordinary Shares are entitled to consideration other than cash or Equity Consideration (as defined in the Tranche 1 Warrant Agreement or the Tranche 2 Warrant Agreement, as applicable) (the “Other Consideration”) and (iii) (1) the Warrant Share Number multiplied by the amount, if any, by which (w) the fair market value of the Other Consideration exceeds (x) the Exercise Price multiplied by the percentage of the total consideration for the Fundamental Transaction represented by the Other Consideration (the “Other Consideration Percentage”) is less than (2) (y) the Black Scholes Value multiplied by (z) the Other Consideration Percentage, then Noble will pay for each such Emergence Warrant an amount of cash equal to the product of the Black Scholes Value multiplied by the Other Consideration Percentage.

Mandatory Exercise

Each of the Tranche 1 Warrant Agreement and the Tranche 2 Warrant Agreement provides that, from and after the date on which the Mandatory Exercise Condition (as described below) has occurred and is continuing, each of Noble, on the one hand, and holders of Tranche 1 Warrants or Tranche 2 Warrants representing at least 20% of the Tranche 1 Warrants or the Tranche 2 Warrants (as applicable) issued on the Effective Date (the “Required Mandatory Exercise Warrantholders”), on the other hand, have the right and option (but not the obligation) to (i) in the case of Noble, cause all of the Tranche 1 Warrants or the Tranche 2 Warrants (as applicable), and (ii) in the case of the electing Required Mandatory Exercise Warrantholders, cause all of their respective Tranche 1 Warrants or Tranche 2 Warrants (as applicable), to be automatically exercised on a cashless basis upon the terms and subject to the conditions set forth therein (a “Mandatory Exercise”). Pursuant to each of the Tranche 1 Warrant Agreement and the Tranche 2 Warrant Agreement, the “Mandatory Exercise Condition” has occurred if (i) Noble meets or exceeds certain trading price and volume thresholds or (ii) three and one-half

31

years have elapsed since the Effective Date. A Mandatory Exercise entitles the holder of each Emergence Warrant subject thereto to (i) the number of Ordinary Shares issuable upon exercise of such Emergence Warrant on a cashless basis and (ii) an amount payable in cash, Ordinary Shares or a combination thereof (in Noble’s sole discretion) equal to the Black Scholes Value multiplied by a fraction, (A) the numerator of which is (x) the number of Ordinary Shares issuable upon exercise of such Emergence Warrant on a cash basis minus (y) the number of Ordinary Shares issuable upon exercise of such Emergence Warrant on a cashless basis, and (B) the denominator of which is the number of Ordinary Shares issuable upon exercise of such Emergence Warrant on a cash basis.

Penny Warrants

On the Effective Date, in connection with the effectuation of the Plan, Noble entered into an Ordinary Share Purchase Warrant Agreement (the “Penny Warrant Agreement” and, collectively with the Emergence Warrant Agreements, the “Warrant Agreements”) with the Warrant Agent which provides for Noble’s issuance of an aggregate of up to 6,463,182 Ordinary Share Purchase Warrants (the “Penny Warrants”) to purchase an aggregate of 6,463,182 Ordinary Shares. Each Penny Warrant permits the holder thereof (a “Penny Warrantholder”), upon the terms and subject to the limitations on exercise and the conditions set forth in such Penny Warrant Agreement, including that a Penny Warrantholder may not exercise any Penny Warrant if doing so would result in the Penny Warrantholder beneficially owning, for purposes of Section 13(d) of the Exchange Act and applicable rules, in excess of 9.9% of the Ordinary Shares, subject to the terms of the Penny Warrant Agreement, at any time and from time to time after the issuance date, to subscribe for and purchase from Noble one Ordinary Share at an exercise price of $0.01 per share (subject to adjustment as provided in the Penny Warrant Agreement). The Penny Warrants have no stated expiration date; however, the Penny Warrants will expire 30 days after the consummation of a Fundamental Transaction (as defined in the Penny Warrant Agreement) to the extent any Penny Warrants then remain outstanding. In the event of a Fundamental Transaction, the Penny Warrants will be converted into the right to receive upon exercise such consideration in the Fundamental Transaction as the Penny Warrantholder would have been entitled to receive with respect to the Ordinary Shares that would otherwise have been deliverable on exercise of the Penny Warrants held by the Penny Warrantholder.

Pursuant to the Penny Warrant Agreement, no holder of Penny Warrants shall have or exercise any rights held by holders of Ordinary Shares solely by virtue thereof as a holder of Penny Warrants, including the right to vote and, except as provided in the Penny Warrant Agreement, to receive dividends and other distributions as a holder of Ordinary Shares prior to the issuance to the holder of Penny Warrants of the Ordinary Shares which such holder is then entitled to receive upon the due exercise of the Penny Warrants.

The following discussion summarizes certain United States (for purposes of this section, “U.S.”) federal income tax considerations of owning and disposing of the Ordinary Shares by a U.S. Holder (defined below).

This summary is based on the U.S. Internal Revenue Code of 1986, as amended (the “Tax Code”), the U.S. Treasury Regulations promulgated thereunder (the “Treasury Regulations”), judicial decisions and published administrative rules and pronouncements of the U.S. Internal Revenue Service (the “IRS”), all as in effect on the date hereof (collectively, “Applicable U.S. Tax Law”). Changes in the rules or new interpretations of the rules may have retroactive effect and could significantly affect the U.S. federal income tax considerations described below. We have not requested, and will not request, any ruling or determination from the IRS or any other taxing authority with respect to the tax considerations discussed herein, and the discussion below is not binding upon the IRS or the courts. No assurance can be given that the IRS would not assert, or that a court would not sustain, a different position than any position discussed herein.

This summary does not address state, local or non-income tax considerations, nor does it purport to address all aspects of U.S. federal income taxation that may be relevant to a U.S. Holder in light of its individual circumstances or to a U.S. Holder that may be subject to special tax rules (such as persons who are related to the Debtors within the meaning of the Tax Code, persons liable for alternative minimum tax, persons whose functional currency is not the U.S. dollar, U.S. expatriates, persons who actually or constructively own or will own 10% or more (by vote or value) of the equity interest of Noble (and any person that is related to Noble), broker-dealers, banks, mutual funds, insurance companies, financial institutions, small business investment companies, regulated investment companies, tax exempt organizations, controlled foreign corporations, passive foreign investment companies, partnerships (or other entities treated as partnerships or other pass-through entities), beneficial owners of partnerships (or other entities treated as partnerships or other pass-through entities), subchapter S corporations, persons who hold the Ordinary Shares as part of a straddle, hedge, conversion transaction or other integrated investment, persons using a mark-to-market method of accounting and persons who are in bankruptcy). Furthermore, this summary assumes that the Ordinary Shares are held only as “capital assets” (within the meaning of section 1221 of the Tax Code).

For purposes of this discussion, a “U.S. Holder” is a holder of Ordinary Shares that is: (1) an individual citizen or resident of the United States for U.S. federal income tax purposes; (2) a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States, any state thereof or the District of Columbia; (3) an estate the income of which is subject to U.S. federal income taxation regardless of the source of such income; or (4) a trust (A) if a court within the United States is able to exercise primary jurisdiction over the trust’s administration and one or more United States persons (within the meaning of section 7701(a)(30) of the Tax Code) have authority to control all substantial decisions of the trust or (B) that has a valid election in effect under applicable Treasury Regulations to be treated as a United States person.

If a partnership (or other entity treated as a partnership or other pass-through entity for U.S. federal income tax purposes) is a holder of Ordinary Shares, the tax treatment of a partner (or other beneficial owner) generally will depend upon the status of the partner (or other beneficial owner) and the activities of the entity. Partners (or other beneficial owners) of partnerships (or other entities treated as partnerships or other pass-through entities) that are holders of Ordinary Shares should consult their respective tax advisors regarding the U.S. federal income tax considerations of the Ordinary Shares.

THE FOLLOWING SUMMARY OF CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT A SUBSTITUTE FOR CAREFUL TAX PLANNING AND ADVICE BASED UPON THE INDIVIDUAL CIRCUMSTANCES PERTAINING TO A HOLDER OF ORDINARY SHARES. ALL HOLDERS OF ORDINARY SHARES ARE URGED TO CONSULT THEIR TAX ADVISORS AS TO THE U.S. FEDERAL, STATE, LOCAL, NON-U.S., NON-INCOME AND OTHER TAX CONSIDERATIONS OF THE ORDINARY SHARES.

33

Dividends Paid on the Ordinary Shares

Subject to the discussion below regarding the passive foreign investment company (“PFIC”) rules, any distributions made by Noble out of current or accumulated earnings and profits (as determined for U.S. federal income tax purposes and including any taxes withheld from such distributions) with respect to the Ordinary Shares generally should be taxable to a U.S. Holder as foreign source ordinary dividend income. Distributions in excess of current and accumulated earnings and profits should be treated as a non-taxable return of capital to the extent of a U.S. Holder’s basis in the Ordinary Shares and thereafter as capital gain. Noble does not intend to determine its earnings and profits on the basis of U.S. federal income tax principles and, as a result, U.S. Holders should expect to treat all distributions on the Ordinary Shares as dividends.

In general, dividends paid with respect to the Ordinary Shares to certain non-corporate U.S. Holders will be treated as “qualified dividend income,” which is taxable to such U.S. Holder at preferential capital gain tax rates provided that (i) the Ordinary Shares are readily tradable on an established securities market in the United States (such as the New York Stock Exchange) or Noble is eligible for the benefits of a comprehensive income tax treaty with the United States that the IRS has determined is satisfactory and that includes an exchange of information program, (ii) as discussed below under “—PFIC,” Noble is not a PFIC for the taxable year during which the dividend is paid or the immediately preceding taxable year, and (iii) certain holding period and other requirements are satisfied. For purposes of clause (i) above, the Ordinary Shares should be treated as readily tradable on an established securities market in the United States so long as they are listed on the New York Stock Exchange.

Sale, Exchange or Other Disposition of the Ordinary Shares

Unless a non-recognition provision applies, and subject to the discussion below under “—PFIC,” U.S. Holders generally will recognize capital gain or loss upon the sale, exchange or other disposition of the Ordinary Shares. Such capital gain or loss will be long-term capital gain or loss if, at the time of the sale, exchange or other disposition, the U.S. Holder held the Ordinary Shares for more than one year. Long-term capital gains of an individual taxpayer generally are taxed at preferential rates. The deductibility of capital losses is subject to certain limitations.

PFIC

A special set of U.S. federal income tax rules applies to ownership interests in a PFIC. A non-U.S. corporation is a PFIC in any taxable year in which, after taking into account certain look-through rules, either (i) at least 75% of its gross income is passive income or (ii) at least 50% of the average value (determined on a quarterly basis) of its assets is attributable to assets that produce or are held to produce passive income. In making this determination, the non-U.S. corporation is treated as earning its proportionate share of any income and owning its proportionate share of any assets of a subsidiary corporation in which it owns, directly or indirectly, a 25% or greater interest, by value. Passive income generally includes, but is not limited to, dividends, interest, rents, royalties and capital gains. If Noble is a PFIC at any time during which a U.S. Holder owns the Ordinary Shares, the U.S. Holder would be subject to additional U.S. information return filing requirements and the potentially materially adverse rules discussed below. While it is not free from doubt, we believe that Noble has not been, and will not become, a PFIC with respect to any taxable year.

If Noble is classified as a PFIC for any taxable year during which a U.S. Holder owns Ordinary Shares, the PFIC rules may alter the tax consequences of owning the Ordinary Shares with respect to gains from the sale, exchange or other disposition of, and “excess distributions” with respect to, the Ordinary Shares. Under the “default PFIC regime,” in general, an “excess distribution” is any distribution to a U.S. Holder that is greater than 125% of the average annual distributions received by the U.S. Holder (including return of capital distributions) during the three preceding taxable years or, if shorter, a U.S. Holder’s holding period. If Noble is classified as a PFIC for any taxable year during which a U.S. Holder owns Ordinary Shares, gains from the sale, exchange or

34

other disposition of, and “excess distributions” with respect to, the Ordinary Shares would be allocated ratably over a U.S. Holder’s entire holding period and taxed at the highest ordinary income tax rate in effect for each such taxable year (subject to certain exceptions). Moreover, interest would be charged retroactively at the rate applicable to underpayments of tax (with respect to each such tax year’s ratable allocation) through the date of the sale, exchange or other disposition of, and “excess distributions” with respect to, the Ordinary Shares.

Noble does not intend to prepare or provide the information that would enable a U.S. Holder to make a “qualified electing fund” election to opt out of the default PFIC regime. U.S. Holders should consult with their tax advisors with respect to whether the unfavorable PFIC rules may be avoidable by electing to mark the Ordinary Shares to market.

The rules relating to PFICs are extremely complex and U.S. Holders are urged to consult their tax advisors regarding the tax considerations of owning Ordinary Shares in the event that Noble is treated as a PFIC during any taxable year during which a U.S. Holder will own Ordinary Shares.

The above discussion assumes Noble is not treated as a controlled foreign corporation (a “CFC”) under Applicable U.S. Tax Law, but no assurance can be made in that regard. U.S. Holders are urged to consult their tax advisors regarding the tax considerations of owning Ordinary Shares in the event that Noble is treated as a CFC.

Foreign Asset Reporting

Each U.S. Holder that is an individual that holds, or that is a corporation, partnership or trust formed or availed for the purpose of holding, “specified foreign financial assets” with an aggregate value in excess of $50,000 on the last day of the tax year or more than $75,000 at any time during the tax year (or such larger values as specified in the applicable Treasury Regulations), generally is required to file an information report with respect to such assets with its tax returns. A U.S. Holder is urged to consult its tax advisors regarding its information reporting obligations, if any, with respect to its ownership and disposition of the Ordinary Shares.

Information Reporting and Backup Withholding

In general, information reporting requirements will apply to amounts paid to a U.S. Holder in respect of the Ordinary Shares and the proceeds received by a U.S. Holder from the sale, exchange or other disposition of the Ordinary Shares, unless such U.S. Holder is an exempt recipient, such as a corporation. Backup withholding may apply to such payments if the U.S. Holder fails to provide a taxpayer identification number or a certification that it is not subject to backup withholding.

Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a U.S. Holder’s U.S. federal income tax liability provided the required information is timely furnished to the IRS.

CAYMAN ISLANDS TAX CONSIDERATIONS

The following is a discussion on certain Cayman Islands income tax consequences of an investment in our securities. The discussion is a general summary of present law, which is subject to prospective and retroactive change. It is not intended as tax advice, does not consider any investor’s particular circumstances and does not consider tax consequences other than those arising under Cayman Islands law.

Under Existing Cayman Islands Laws

Payments of dividends and capital in respect of our securities will not be subject to taxation in the Cayman Islands and no withholding will be required on the payment of a dividend or capital to any holder of the securities nor will gains derived from the disposal of the securities be subject to Cayman Islands income or corporate tax. The Cayman Islands currently have no income, corporate or capital gains tax and no estate duty, inheritance tax or gift tax.

No stamp duty is payable in respect of the issue of our securities or on an instrument of transfer in respect of our securities.

The Company has been incorporated under the laws of the Cayman Islands as an exempted company with limited liability and, as such, has applied for and received an undertaking from the Financial Secretary of the Cayman Islands in the following form.

The Tax Concessions Act (As Revised) Undertaking as to Tax Concessions

In accordance with the provision of section 6 of The Tax Concessions Act (As Revised), the Financial Secretary undertakes with the Company:

1. That no law which is hereafter enacted in the Cayman Islands imposing any tax to be levied on profits, income, gains or appreciations shall apply to the Company or its operations; and

2. In addition, that no tax to be levied on profits, income, gains or appreciations or which is in the nature of estate duty or inheritance tax shall be payable:

2.1 on or in respect of the shares, debentures or other obligations of the Company; or

2.2 by way of the withholding in whole or part, of any relevant payment as defined in Section 6(3) of the Tax Concessions Act (As Revised).

3. These concessions shall be for a period of 20 years from November 30, 2020.

PLAN OF DISTRIBUTION

The selling shareholders, or their pledgees, donees, transferees, or any of their successors in interest selling shares received from a named selling shareholder as a gift, partnership distribution or other permitted transfer after the date of this prospectus (all of whom may be selling shareholders), may sell some or all of the securities covered by this prospectus from time to time on any stock exchange or automated interdealer quotation system on which our Ordinary Shares are listed, in the over-the-counter market, in privately negotiated transactions or otherwise, at fixed prices that may be changed, at market prices prevailing at the time of sale, at prices related to prevailing market prices or at prices otherwise negotiated. The selling shareholders may sell the securities by one or more of the following methods, without limitation:

• block trades in which the broker or dealer so engaged will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

• purchases by a broker or dealer as principal and resale by the broker or dealer for its own account pursuant to this prospectus;

• an exchange distribution in accordance with the rules of any stock exchange on which our Ordinary Shares are listed;

• ordinary brokerage transactions and transactions in which the broker solicits purchases;

• privately negotiated transactions;

• “at-the-market” offering transactions;

• short sales, either directly or with a broker-dealer or affiliate thereof;

• through the writing of options on the Ordinary Shares, whether or not the options are listed on an options exchange;

• through loans or pledges of the Ordinary Shares to a broker-dealer or an affiliate thereof;

• by entering into transactions with third parties who may (or may cause others to) issue securities convertible or exchangeable into, or the return of which is derived in whole or in part from the value of, our Ordinary Shares;

• through the distribution by any selling shareholder to its partners, members or equity holders;

• one or more underwritten offerings on a firm commitment or best efforts basis; and

• any combination of any of these methods of sale.

For example, the selling shareholders may engage brokers and dealers, and any brokers or dealers may arrange for other brokers or dealers to participate in effecting sales of our Ordinary Shares. These brokers, dealers or underwriters may act as principals, or as an agent of a selling shareholder. Broker-dealers may agree with a selling shareholder to sell a specified number of Ordinary Shares at a stipulated price. If the broker-dealer is unable to sell the Ordinary Shares acting as agent for a selling shareholder, it may purchase as principal any unsold securities at the stipulated price. Broker-dealers who acquire Ordinary Shares as principals may thereafter resell the Ordinary Shares from time to time in transactions on any stock exchange or automated interdealer quotation system on which the Ordinary Shares are then listed, at prices and on terms then prevailing at the time of sale, at prices related to the then-current market price or in negotiated transactions. Broker-dealers may use block transactions and sales to and through broker-dealers, including transactions of the nature described above.

A selling shareholder may also enter into hedging and/or monetization transactions. For example, a selling shareholder may:

• enter into transactions with a broker-dealer or affiliate of a broker-dealer or other third party in connection with which that other party will become a selling shareholder and engage in short sales of our Ordinary Shares under this prospectus, in which case the other party may use Ordinary Shares received from the selling shareholder to close out any short position;

37

• sell short our Ordinary Shares under this prospectus and use Ordinary Shares held by the selling shareholder to close out any short position;

• enter into options, forwards or other transactions that require the selling shareholder to deliver, in a transaction exempt from registration under the Securities Act, Ordinary Shares to a broker-dealer or an affiliate of a broker-dealer or other third party who may then become a selling shareholder and publicly resell or otherwise transfer Ordinary Shares under this prospectus;

• loan or pledge Ordinary Shares to a broker-dealer or affiliate of a broker-dealer or other third party who may then become a selling shareholder and sell the loaned shares or, in an event of default in the case of a pledge, become a selling shareholder and sell the pledged shares, under this prospectus. As and when a selling shareholder takes such actions, the number of securities offered under this prospectus on behalf of such selling shareholder will decrease. The plan of distribution for that selling shareholder’s Ordinary Shares will otherwise remain unchanged; or

• enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by the selling shareholder or borrowed from the selling shareholder or others to settle those sales or to close out any related open borrowings of Ordinary Shares, and may use securities received from the selling shareholder in settlement of those derivatives to close out any related open borrowings of Ordinary Shares. The third party in such sale transactions may be an underwriter and, if applicable, will be identified as such in the applicable prospectus supplement (or a post-effective amendment).

The selling shareholders may also sell Ordinary Shares pursuant to Rule 144 under the Securities Act.

We do not know of any arrangements by the selling shareholders for the sale of our Ordinary Shares.

To the extent required under the Securities Act, the aggregate amount of selling shareholders’ Ordinary Shares being offered and the terms of the offering, the names of any agents, brokers, dealers or underwriters and any applicable commission with respect to a particular offer will be set forth in an accompanying prospectus supplement. Any underwriters, dealers, brokers or agents participating in the distribution of the Ordinary Shares may receive compensation in the form of underwriting discounts, concessions, commissions or fees from a selling shareholder and/or purchasers of selling shareholders’ Ordinary Shares for whom they may act (which compensation as to a particular broker-dealer might be in excess of customary commissions).

The selling shareholders and any underwriters, brokers, dealers or agents that participate in the distribution of the Ordinary Shares may be deemed to be “underwriters” within the meaning of the Securities Act, and any discounts, concessions, commissions or fees received by them and any profit on the resale of the Ordinary Shares sold by them may be deemed to be underwriting discounts and commissions.

The selling shareholders and other persons participating in the sale or distribution of the Ordinary Shares will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M. This regulation may limit the timing of purchases and sales of any of the Ordinary Shares by the selling shareholders and any other person. The anti-manipulation rules under the Exchange Act may apply to sales of ordinary shares in the market and to the activities of the selling shareholders and their affiliates. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of the Ordinary Shares to engage in market-making activities with respect to the particular Ordinary Shares being distributed for a period of up to five business days before the distribution. These restrictions may affect the marketability of the Ordinary Shares and the ability of any person or entity to engage in market-making activities with respect to the Ordinary Shares.

38

To the extent permitted by applicable law, this plan of distribution may be modified in a prospectus supplement or otherwise.

We agreed to register the Ordinary Shares under the Securities Act and to keep the registration statement of which this prospectus is a part effective for a specified period of time. We have also agreed to indemnify the selling shareholders against certain liabilities, including liabilities under the Securities Act. The selling shareholders have agreed to indemnify us in certain circumstances against certain liabilities, including liabilities under the Securities Act.

We will not receive any proceeds from sales of any Ordinary Shares by the selling shareholders.

We cannot assure you that the selling shareholders will sell all or any portion of the Ordinary Shares offered hereby. All of the foregoing may affect the marketability of the securities offered hereby.

39

Item 15. Indemnification of Directors and Officers

Noble Corporation (“Noble”) is an exempted company incorporated in the Cayman Islands with limited liability. Cayman Islands law does not limit the extent to which a company’s articles of association may provide for the indemnification of its directors, officers, employees and agents except to the extent that such provision may be held by the Cayman Islands courts to be contrary to public policy.

Noble’s articles of association provide the following:

Article 44.1 of Noble’s articles of association provides that every Noble director and officer and every former Noble director and officer shall be indemnified out of Noble’s assets against any liability, action, proceeding, claim, demand, costs, damages or expenses, including legal expenses, whatsoever which they or any of them may incur as a result of any act or failure to act in carrying out their functions other than such liability (if any) that they may incur by reason of their own actual fraud, wilful neglect or wilful default. No indemnified person shall be liable to Noble for any loss or damage incurred by Noble as a result (whether direct or indirect) of the carrying out of their functions unless that liability arises through the actual fraud, wilful neglect or wilful default of such indemnified person. No person shall be found to have committed actual fraud, wilful neglect or wilful default unless or until a court of competent jurisdiction shall have made a finding to that effect.

Article 44.2 of Noble’s articles of association provides that Noble shall advance to each indemnified person reasonable attorneys’ fees and other costs and expenses incurred in connection with the defense of any action, suit, proceeding or investigation involving such indemnified person for which indemnity will or could be sought. In connection with any advance of any expenses under Noble’s articles of association, the indemnified person shall execute an undertaking to repay the advanced amount to Noble if it shall be determined by final judgment or other final adjudication that such indemnified person was not entitled to indemnification pursuant to Article 44.2. If it shall be determined by a final judgment or other final adjudication that such indemnified person was not entitled to indemnification with respect to such judgment, costs or expenses, then such party shall not be indemnified with respect to such judgment, costs or expenses and any advancement shall be returned to Noble (without interest) by the indemnified person.

II-1

Article 44.3 of Noble’s articles of association provides that the directors, on behalf of Noble, may purchase and maintain insurance for the benefit of any director or officer against any liability which, by virtue of any rule of law, would otherwise attach to such person in respect of any negligence, default, breach of duty or breach of trust of which such person may be guilty in relation to Noble. Without prejudice to the generality of the foregoing, Noble shall use commercially reasonable efforts to purchase and maintain insurance for the benefit of the Investor Director (as defined in Noble’s articles of association) against any liability which, by virtue of any rule of law, would otherwise attach to such person in respect of any negligence, default, breach of duty or breach of trust of which such person may be guilty in relation to Noble.

Noble has entered into an indemnity agreement with each of its directors and executive officers to supplement the indemnification protection available under Noble’s articles of association referred to above. These indemnity agreements generally provide that Noble will indemnify the parties thereto to the fullest extent permitted by law.

Noble also maintains insurance to protect itself and its directors, officers, employees and agents against expenses, liabilities and losses incurred by such persons in connection with their services in the foregoing capacities.

Item 17. Undertakings

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

II-3

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

II-4

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
