The Record Date (as defined below) for the consent solicitation is May 6, 2011. The expiration time for the consent solicitation is 5:00 p.m., New York City time, on Friday, May 27, 2011, unless extended (such time and date, as it may be extended, the “Expiration Time”). Consents may be revoked at any time prior to the earlier of (i) the Expiration Time, and (ii) the time at which the required consents have been received (the “Revocation Time”). Any notice of revocation received after the Revocation Time will not be effective.
 
Pursuant to the Agreement and Plan of Merger, dated as of February 6, 2011 (as amended, the “Merger Agreement”), among Ensco plc (“Ensco”), Pride International, Inc. (“Pride”), ENSCO International Incorporated, a Delaware corporation and an indirect wholly owned subsidiary of Ensco, and ENSCO Ventures LLC, a Delaware limited liability company and an indirect wholly owned subsidiary of Ensco (“Merger Sub”), subject to satisfaction of the conditions stated therein, Merger Sub will merge with and into Pride, with Pride surviving as an indirect wholly owned subsidiary of Ensco (the “Merger”). Closing of the Merger is expected to occur on May 31, 2011.
 
Ensco is soliciting the consents of the holders of the above-referenced securities of Pride (all such series, collectively, the “Securities”) to certain proposed amendments to the Indenture (as defined below). In connection with the consent solicitation, Ensco is offering to issue an unconditional and irrevocable guarantee (the “Ensco Guarantee”) of the prompt payment, when due, of any amount owed to the holders of the Securities issued under the indenture, dated July 1, 2004, by and among Pride and The Bank of New York Mellon, as successor to JPMorgan Chase Bank, N.A., as trustee (“Trustee”), as amended (the “Indenture”), and any other amounts due pursuant to the Indenture to record holders of Securities who provide valid and unrevoked consents prior to the Expiration Time of this consent solicitation, upon the terms and subject to the conditions set forth in this Consent Solicitation/Prospectus Supplement (the “Consent Solicitation/Prospectus Supplement”) and the related letter of consent (the “Letter of Consent”). The Ensco Guarantee will be an unsecured unsubordinated obligation of Ensco and will rank pari passu with Ensco’s other general unsecured obligations.
 
In order for the proposed amendments to be adopted, consents must be received in respect of at least a majority in principal amount of Securities outstanding on the Record Date (as defined below), with all series of the Securities voting as a single class. Promptly upon receipt of the required consents and the closing of the Merger, Ensco, Pride and the Trustee will enter into a supplemental indenture that will set forth the amendments to the Indenture. Ensco will execute and deliver the Ensco Guarantee concurrently with the execution of the supplemental indenture. The proposed amendments will become effective upon execution and delivery of the supplemental indenture and Ensco’s execution and delivery of the Ensco Guarantee.
 
If the required consents are obtained, the Merger closes and Pride, Ensco and the Trustee enter into a supplemental indenture, all holders of the Securities will be bound by the amended Indenture and all holders of the Securities will receive the Ensco Guarantee pursuant to the terms of the supplemental indenture, even if they have not consented to the proposed amendments. If the required consents are not obtained, the Ensco Guarantee will not be provided to the holders of the Securities.
 
Providing your consent involves risks. For a discussion of factors you should consider before you decide whether to consent, see “Forward Looking Information and Risk Factors” on page S-3 of this Consent Solicitation/Prospectus Supplement, “Risk Factors” under Part I, Item IA in Ensco’s Annual Report on Form 10-K for the year ended December 31, 2010, and Ensco’s most recently filed Quarterly Reports on Form 10-Q, and any amendments thereto, and “Risk Factors” set forth in Ensco’s Registration Statement on Form S-4, which was declared effective by the U.S. Securities and Exchange Commission (the “SEC”) on April 25, 2011.

You should rely only on the information contained or incorporated by reference in this Consent Solicitation/Prospectus Supplement and the accompanying prospectus. No person is authorized to give any information or to make any representations other than those contained or incorporated by reference in this Consent Solicitation/Prospectus Supplement or the accompanying Base Prospectus (as defined). If anyone provides you with different or inconsistent information, you should not rely on it. This Consent Solicitation/Prospectus Supplement and the accompanying Base Prospectus are not an offer to sell or solicitation of an offer to buy any securities in any jurisdiction where such offer is unlawful. None of the delivery of this Consent Solicitation/Prospectus Supplement or the accompanying Base Prospectus or the issuance of the Ensco Guarantee will, under any circumstances, create any implication that there has been no change in our affairs since the date of this Consent Solicitation/Prospectus Supplement or the accompanying Base Prospectus or that the information contained or incorporated by reference is correct as of any time subsequent to the date of such information. Our business, financial condition, results of operation and prospects may have changed since those dates.
 
References in this Consent Solicitation/Prospectus Supplement to “we,” “us” and “our” are to Ensco plc and Pride, collectively, and their consolidated subsidiaries unless otherwise stated or the context so requires.
 
The terms of the Ensco Guarantee are fully set forth in this Consent Solicitation/Prospectus Supplement. The Ensco Guarantee is not a debt security as described in the Prospectus, dated May 6, 2011, included in the Registration Statement on Form S-3 filed with the SEC by Ensco on May 6, 2011 (the “Base Prospectus”) and is not being issued under the Ensco Indenture (as defined). The Base Prospectus does not set forth any terms of the Ensco Guarantee. If information in this Consent Solicitation/Prospectus Supplement is inconsistent with that in the Base Prospectus, then the information set forth in, and incorporated by reference into, this Consent Solicitation/Prospectus Supplement shall supersede that which is set forth in the Base Prospectus.
 
FORWARD LOOKING INFORMATION
 
The information contained in this Consent Solicitation/Prospectus Supplement is accurate only as of the date hereof.
 
This Consent Solicitation/Prospectus Supplement and the accompanying Base Prospectus and documents incorporated herein by reference contain some forward looking statements that set forth anticipated results based on management’s plans and assumptions. From time to time, we also provide forward looking statements in other materials we release to the public, as well as oral forward looking statements. Such statements give our current expectations or forecasts of future events; they do not relate strictly to historical or current facts. We have tried, wherever possible, to identify such statements by using words such as “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” “will,” “target”, “forecast” and similar expressions in connection with any discussion of future operating or financial performance or business plans or prospects. In particular, these include statements relating to future actions, business plans and prospects, future performance or results of current and anticipated products, expenses, interest rates, foreign exchange rates, the outcome of contingencies, such as legal proceedings, and financial results.
 
We cannot guarantee that any forward looking statement will be realized. Achievement of future results is subject to risks, uncertainties and potentially inaccurate assumptions. Should known or unknown risks or uncertainties materialize, or should underlying assumptions prove inaccurate, actual results could differ materially from past results and those anticipated, estimated or projected. You should bear this in mind as you consider forward looking statements.
 
You should take care not to place undue reliance on forward looking statements, which represent Ensco’s views only as of the date they are made. We undertake no obligation to publicly update forward looking statements, whether as a result of new information, future events or otherwise. You are advised, however, to consult any further disclosures we make on related subjects in our Quarterly Reports on Form 10-Q and Current Reports on Form 8-K filed with the SEC. Also note that Ensco provides cautionary discussion of risks, uncertainties and possibly inaccurate assumptions relevant to our businesses and the Merger in Ensco’s Annual Report on Form 10-K for the year ended December 31, 2010, and Ensco’s most recently filed Quarterly


S-ii


Table of Contents

Reports on Form 10-Q, and any amendments thereto, and Ensco’s Registration Statement on Form S-4, which was declared effective by the SEC on April 25, 2011. These are factors that, individually or in the aggregate, may cause our actual results to differ materially from expected and historical results. We note these factors for investors as permitted by the Private Securities Litigation Reform Act of 1995. You should understand that it is not possible to predict or identify all such factors. Consequently, you should not consider those factors to be a complete discussion of all potential risks or uncertainties.

RISK FACTORS
 
You should carefully consider each of the risks and uncertainties under the headings “Risk Factors” under Part I, Item IA in Ensco’s Annual Report on Form 10-K for the year ended December 31, 2010, and Ensco’s most recently filed Quarterly Reports on Form 10-Q, and any amendments thereto, and “Risk Factors” set forth in Ensco’s Registration Statement on Form S-4, which was declared effective by the SEC on April 25, 2011, which are incorporated by reference into this Consent Solicitation/Prospectus Supplement, and all of the other information included or incorporated by reference in this Consent Solicitation/Prospectus Supplement. The risks below should be considered along with the other risks described in the reports incorporated by reference into this Consent Solicitation/Prospectus Supplement. See “Where You Can Find More Information” for the location of information incorporated by reference into this Consent Solicitation/Prospectus Supplement.
 
The Ensco Guarantee is unsecured and will be effectively junior to secured indebtedness that Ensco may incur in the future and will be structurally subordinated to the obligations of Ensco’s subsidiaries.
 
The Ensco Guarantee will be an unsecured unsubordinated obligation of Ensco and rank pari passu with all of Ensco’s unsecured debt obligations. Holders of any secured debt that Ensco may incur in the future may foreclose on the assets securing such debt, reducing the cash flow from the foreclosed property available for payment of unsecured debt, including the Ensco Guarantee. Holders of secured debt also would have priority over unsecured creditors in the event of our bankruptcy, liquidation or similar proceeding. As a result, the Ensco Guarantee will be effectively junior to any secured debt that Ensco may issue in the future. Ensco currently does not have any secured debt outstanding. Although Ensco is subject to certain limitations on liens, there are exceptions to these limitations which may permit Ensco to incur secured debt. The Ensco Guarantee will also be structurally subordinated to the obligations of Ensco’s subsidiaries. Holders of the Securities will not have any claim as a creditor against subsidiaries of Ensco that are not guarantors of the Securities, other than Pride (subject to Ensco’s right to substitute itself as obligor).
 
If the proposed amendments to the Indenture are approved and the supplemental indenture is executed, Pride will be subject to fewer restrictions on its conduct than it is currently subject to and assets of Pride may be transferred to subsidiaries of Ensco or third parties that are not parties to the Indenture and are not providing a guarantee of the Securities.
 
If the proposed amendments to the Indenture become effective, the covenants in the amended indenture would generally impose fewer restrictions on Pride’s conduct than the covenants currently in the Indenture. The proposed amendments would allow Pride to take actions that would otherwise have been restricted or conditioned. Specifically, Pride will no longer be subject to certain restrictions on its ability to, among other things, merge or consolidate, sell all or substantially all of its assets, effect a conversion of its legal status (to the extent not already permitted by the Indenture), enter into sale and leaseback transactions with respect to certain property and subject certain property and shares of certain subsidiaries to any mortgage, pledge, security interest or lien. Therefore, assets of Pride may be transferred to subsidiaries of Ensco or third parties that are not parties to the Indenture and are not providing a guarantee of the Securities, which may result in materially fewer assets of Pride being available to satisfy Pride’s obligations under the Securities. See “The Consent Solicitation — Description of the Proposed Amendments” and Annex A to this Consent Solicitation/Prospectus Supplement for more information about the differences between what actions are currently restricted by the covenants currently applicable to the Securities and what actions would be restricted by the covenants following the effectiveness of the proposed amendments.

RATIO OF EARNINGS TO FIXED CHARGES
 
For the purpose of computing the ratio of earnings to fixed charges, “earnings” consist of income from continuing operations before income taxes, fixed charges and amortization of capitalized interest, less income from continuing operations before income taxes attributable to noncontrolling interests and interest capitalized. “Fixed charges” consist of interest expensed and capitalized and estimates of interest within rental expense. The ratios were calculated by dividing the sum of the fixed charges into the sum of the earnings. The following ratios do not reflect the Merger. Our consolidated ratio of earnings to fixed charges for each of the fiscal years ended December 31, 2006 through 2010 and the three months ended March 31, 2011 are set forth below:

THE CONSENT SOLICITATION
 
Introduction
 
In connection with the proposed amendments to the Indenture, Ensco is seeking valid and unrevoked consents of registered holders of the majority in aggregate principal amount of the Securities outstanding voting as a single class at 5:00 p.m. New York City time, on May 27, 2011, the record date for determining the holders of Securities entitled to deliver consents in connection with this consent solicitation (the “Record Date”). In return for such consents, Ensco is offering to issue the Ensco Guarantee upon the terms and subject to the conditions set forth in this Consent Solicitation/Prospectus Supplement. As of the Record Date, the aggregate principal amount of the Securities outstanding was $1,700,000,000. If the required consents are obtained, all holders of the Securities will be bound by the amended Indenture and all holders of the Securities will receive the Ensco Guarantee even if they have not consented to the proposed amendments.
 
Ensco reserves the right to establish, from time to time, but in all cases prior to receipt of the required consents, any new time for the Record Date and, thereupon, any such new time will be deemed to be the Record Date for purposes of this Consent Solicitation/Prospectus Supplement.
 
Promptly upon receipt of the required consents and the closing of the Merger, Ensco, Pride and the Trustee will enter into a supplemental indenture that will set forth the amendments to the Indenture. Assuming satisfaction or waiver of all conditions to this Consent Solicitation/Prospectus Supplement, Ensco will execute and deliver the Ensco Guarantee concurrently with the execution of the supplemental indenture. The proposed amendments will become effective upon execution and delivery of the supplemental indenture and Ensco’s execution and delivery of the Ensco Guarantee.
 
Separately from this consent solicitation, as a result of the Merger, pursuant to Section 15(d) of the Securities Exchange Act of 1934, as soon as permitted by applicable law, Pride will deregister the Securities. As a result of such deregistration, Pride will no longer be required to file reports with the SEC pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 or pursuant to Section 314 of the


S-4


Table of Contents

Trust Indenture Act of 1939 and Pride will no longer be required to file reports with the Trustee. The deregistration of the Securities will occur when permitted regardless of whether the required consents are obtained and the proposed amendments are made effective.
 
Purpose of Amendments
 
The proposed amendments are intended to allow Ensco to integrate Ensco’s and Pride’s businesses through certain internal corporate restructurings in a more effective manner than could be achieved if the amendments are not made. Ensco would benefit from the flexibility to use Pride’s assets in combination with Ensco’s other assets in order to eliminate redundancies and overlapping operations and to benefit Ensco as a whole. In this regard, the proposed amendments are intended to allow Ensco to more effectively integrate Pride’s business and have Pride and its subsidiaries engage freely in transactions with Ensco and Ensco’s subsidiaries. Specifically, Pride will no longer be subject to certain restrictions on its ability to, among other things, merge or consolidate, sell all or substantially all of its assets, effect a conversion of its legal status (to the extent not already permitted by the Indenture), enter into sale and leaseback transactions with respect to certain property and subject certain property and shares of certain subsidiaries to any mortgage, pledge, security interest or lien. The proposed amendments are intended to allow the integrated company greater flexibility in operations as the proposed amendments will conform certain covenants in the Indenture to the corresponding covenants in the existing Ensco indenture.
 
If the required consents are obtained, the proposed amendments are adopted, the Merger closes and Ensco, Pride and the Trustee enter into a supplemental indenture, the holders of the Securities will be entitled to the Ensco Guarantee and Ensco will have an obligation to file certain SEC reports with the Trustee.
 
Description of the Proposed Amendments
 
Ensco is soliciting the consents of the holders of the Securities to the proposed amendments to the Indenture. The valid and unrevoked consent of the holders of at least a majority in aggregate principal amount of Securities outstanding, voting as a single class is required for the proposed amendments to become effective. The proposed amendments are being presented as one proposal. Consequently, the delivery of a consent by a holder of Securities represents the delivery of a consent to all of the proposed amendments to the Indenture, and a consent purporting to consent to only some of the proposed amendments will not be valid.
 
Ensco is proposing amendments to the provisions in the Indenture relating to (i) the consolidation or merger of Pride or the sale of all or substantially all of Pride’s assets; (ii) the limitation on Pride’s incurrence of liens; (iii) the limitation on sale and leaseback transactions by Pride; and (iv) Pride’s obligation pursuant to the Indenture to file certain SEC reports with the Trustee. Under the indenture dated as of November 20, 1997 between Ensco and Deutsche Bank Trust Company Americas, as trustee (the “Ensco Indenture”), and the supplemental indentures to the Ensco Indenture, dated November 20, 1997 and December 22, 2009 (the “Applicable Ensco Supplemental Indentures”), Ensco is subject to certain similar restrictions. If the required consents are obtained, the Merger closes and Pride, Ensco and the Trustee enter into a supplemental indenture, the Indenture will be amended, where applicable, to provide for restrictions on Ensco and its Subsidiaries (as defined) that are similar to those applicable to Pride and its Subsidiaries related to (i) the consolidation or merger of Ensco or the sale of all or substantially all of Ensco’s assets; (ii) the limitation on liens of Ensco and its Subsidiaries; (iii) the limitation on sale and leaseback transactions by Ensco and its Subsidiaries; and (iv) the obligation to file certain SEC reports with the Trustee. If the proposed amendments are adopted, the Merger closes and Pride, Ensco and the Trustee enter into a supplemental indenture, Ensco will be a party to the supplemental indenture adopting such amendments solely with respect to the proposed covenants related to (i) the limitation on liens of Ensco and its Subsidiaries; (ii) the limitation on sale and leaseback transactions by Ensco and its Subsidiaries; (iii) Ensco’s obligation to file certain SEC reports with the Trustee; (iv) the consolidation or merger of Ensco or the sale of all or substantially all of Ensco’s; assets and (v) Ensco’s obligation to execute and deliver the Ensco Guarantee.
 
The following is a summary of the key proposed amendments to the Indenture, which is qualified by reference to the complete text of the proposed supplemental indenture set forth in Annex A to this Consent


S-5


Table of Contents

Solicitation/Prospectus Supplement (the “Fourth Supplemental Indenture”). The following summary of the proposed amendments is not necessarily presented in the order of importance.
 
Amendment to Covenant Related to Merger or Consolidation of Pride and/or Sale of All or Substantially All of Pride’s Assets to Remove All Limitations and Restrictions on any Transaction Involving Pride or Pride’s Assets
 
The Indenture permits (i) any merger or consolidation of Pride into any other corporation (whether or not affiliated with Pride), or successive consolidations or mergers to which Pride or any successor is a party and (ii) any sale or conveyance of all or substantially all the property of Pride to any other corporation (whether or not affiliated with Pride), provided that, after giving effect to such transaction, no Event of Default (as defined) and no event which, after notice or lapse of time or both, would become an Event of Default, shall have occurred and be continuing and upon any such consolidation, merger, sale or conveyance, other than a consolidation or merger in which Pride is the continuing corporation, the obligations of Pride under the Indenture must be expressly assumed by the corporation formed by the consolidation, the corporation into which Pride has merged or the corporation which shall have acquired all or substantially all of Pride’s assets.
 
This proposed amendment to the Indenture would have the effect of removing the restrictions and limitations on Pride’s or any successor obligor’s ability to enter into any consolidation, merger, sale or conveyance of assets or any other transaction following the Merger. Additionally, the proposed amendment would permit Pride to effect a conversion or enter into any transaction with a subsidiary or affiliate of Ensco, the effect of which would be a change in the legal status of Pride, such as to a limited liability company, a partnership or other legal entity. The proposed amendment will also provide that Ensco may consolidate or merge with or into any other person (whether or not affiliated with Ensco), or convey or transfer of all or substantially all of the assets of Ensco to any other person (whether or not affiliated with Ensco) lawfully entitled to acquire the same; provided that (i) such person (the “Successor”) or the person who beneficially owns all or substantially all of the voting shares of each class of capital stock issued and outstanding at such time of Ensco or such Successor (the “New Parent”) shall be organized and validly existing under the laws of the United States of America, any political subdivision thereof or any State thereof or the District of Columbia, the Bahamas, Barbados, Bermuda, the British Virgin Islands, the Cayman Islands, any of the Channel Islands, Ireland, France, the Kingdom of the Netherlands or any other member of the European Union, Switzerland or the Netherlands Antilles, (ii) the Successor or the New Parent shall agree in writing to submit to jurisdiction to the competent courts of the State of New York or the federal district court sitting in The City of New York and appoints an agent in the State of New York for the service of process, each under terms satisfactory to the Trustee; (iii) the Successor or the New Parent expressly assumes or guarantees by supplemental indenture the due and punctual performance and observance of all of the covenants and conditions of the Ensco Guarantee to be performed by Ensco and any obligations of Ensco under the indenture; (iv) the Board of Directors of Ensco or the comparable governing body of the Successor or the New Parent, as applicable, determines in good faith that such transaction or series of transactions will not adversely affect the interest of the holders of Securities in any material respect; and (v) the Successor or the New Parent delivers to the trustee an officers’ certificate and an opinion of counsel, each stating that the transaction and such supplemental indenture comply with the indenture.
 
Amendment to Covenant Related to Limitation on Liens
 
Subject to certain exceptions, the Indenture provides that Pride will not create or assume, or permit any subsidiary that owns Pride Principal Property (as defined below) to create or assume any mortgage, pledge, lien, charge, security interest or similar encumbrance (a “Lien”) of or upon any Pride Principal Property or any shares of capital stock or indebtedness of any such Subsidiary, unless the Securities are secured by such Lien equally and ratably with any and all other indebtedness or obligations thereby secured. The Indenture defines Pride “Principal Property” as any drilling rig or drillship, or integral portion thereof, owned or leased by Pride or any Subsidiary and used for drilling offshore oil and gas wells, which, in the opinion of Pride’s Board of Directors, is of material importance to the business of Pride and its Subsidiaries taken as a whole, but no such drilling rig or drillship, or portion thereof, shall be deemed of material importance if its net book

Table of Contents

value (after deducting accumulated depreciation) is less than 2% of Pride’s consolidated net tangible assets (as defined in the Indenture).
 
The proposed amendment will amend this provision to replace the existing covenant in its entirety substantially as follows:
 
Ensco shall not, and shall not permit any of its Subsidiaries to, issue, assume or guarantee any Indebtedness for borrowed money secured by any Lien upon any Principal Property or any shares of stock or Indebtedness of any Subsidiary that owns or leases a Principal Property (whether such Principal Property, shares of stock or Indebtedness are now owned or hereafter acquired) without making effective provision whereby the Notes (together with, if Ensco shall so determine, any other Indebtedness or other obligation of Ensco or any Subsidiary) shall be secured equally and ratably with (or, at the option of Ensco, prior to) the Indebtedness so secured for so long as such Indebtedness is so secured. The foregoing restrictions will not, however, apply to Indebtedness secured by Permitted Liens.
 
Notwithstanding the foregoing, Ensco and its Subsidiaries may, without securing the Notes, issue, assume or guarantee Indebtedness that would otherwise be subject to the foregoing restrictions in an aggregate principal amount that, together with all other such Indebtedness of Ensco and its Subsidiaries that would otherwise be subject to the foregoing restrictions (not including Indebtedness permitted to be secured under the definition of Permitted Liens) and the aggregate amount of Attributable Indebtedness deemed outstanding with respect to Sale/Leaseback Transactions (other than Sale/Leaseback Transactions in connection with which Ensco has voluntarily retired any of the Securities, any Pari Passu Indebtedness or any Funded Indebtedness pursuant to Section 4.09(c)) does not at any one time exceed 15% of Consolidated Net Tangible Assets.
 
Amendment to Covenant Related to Limitation on Sale/Leaseback Transactions
 
The Indenture provides that any arrangement with any person providing for the leasing by Pride or a Pride Subsidiary of any Pride Principal Property (except for temporary leases for a term of five years or less), which property has been or is to be sold or transferred by Pride or such Subsidiary to such person (a “Sale/Leaseback Transaction”) is prohibited except in the event that (a) Pride or such Subsidiary would be entitled to incur indebtedness secured by a Lien on the Pride Principal Property to be leased equal in amount to the Attributable Indebtedness (as defined) with respect to such Sale/Leaseback Transaction without equally or ratably securing the securities issued under the Indenture; or (b) Pride applies an amount equal to the fair value of the property sold to the purchase of Pride Principal Property or to the retirement of long-term indebtedness of Pride within nine months of the effective date of any such Sale/Leaseback Transaction. In lieu of applying such amount to such retirement Pride may deliver debt securities to the Trustee for cancellation, such debt securities to be credited at the cost thereof to Pride. Notwithstanding the foregoing, the Indenture provides that Pride or any Subsidiary may enter into any Sale/Leaseback Transaction (which would otherwise be subject to the foregoing restrictions) as long as the Attributable Indebtedness resulting from such Sale/Leaseback Transaction, together with all other exempted debt of Pride and the Subsidiaries, does not at the time exceed 15% of Pride’s consolidated net tangible assets.
 
The proposed amendment will amend this provision to replace the existing covenant in its entirety substantially as follows:
 
Ensco shall not, and shall not permit any Subsidiary to, enter into any Sale/Leaseback Transaction with any Person (other than Ensco or a Subsidiary) unless:
 
(a) Ensco or such Subsidiary would be entitled to incur Indebtedness in a principal amount equal to the Attributable Indebtedness with respect to such Sale/Leaseback Transaction secured by a Lien on the property subject to such Sale/Leaseback Transaction pursuant to Section 4.08 without equally and ratably securing the Notes, pursuant to Section 4.08;
 
(b) after the date of the Fourth Supplemental Indenture and within a period commencing nine months prior to the consummation of such Sale/Leaseback Transaction and ending nine months after such consummation, Ensco or any Subsidiaries shall have expended for property used or to be used


S-7


Table of Contents

in the ordinary course of business of Ensco and its Subsidiaries an amount equal to all or a portion of the net proceeds of such Sale/Leaseback Transaction and Ensco shall have elected to designate such amount as a credit against such Sale/Leaseback Transaction (with any such amount not being so designated to be applied as set forth in clause (c) below or as otherwise permitted); or
 
(c) Ensco, during the nine-month period after the effective date of such Sale/Leaseback Transaction, shall have applied to the voluntary defeasance or retirement of any Securities, any Pari Passu Indebtedness or any Funded Indebtedness an amount equal to the greater of the net proceeds of the sale or transfer of the property leased in such Sale/Leaseback Transaction and the fair value, as determined by the Board of Directors of Ensco and evidenced by a Board Resolution, of such property at the time of entering into such Sale/Leaseback Transaction (in either case adjusted to reflect the remaining term of the lease and any amount expended by Ensco as set forth in clause (b) above).
 
There are currently no Ensco Liens on, or any Ensco Sale/Leaseback Transactions covering, any property that could potentially qualify as Principal Property that would require the Securities to be secured equally and ratably with (or prior to) Indebtedness secured by such Lien.
 
Definitions
 
Set forth below are certain of the defined terms that are included in the proposed amendment for purposes of the Ensco Lien and Ensco Sale/Leaseback covenants set forth above.
 
“Attributable Indebtedness,” when used with respect to any Sale/Leaseback Transaction, means, as at the time of determination, the present value (discounted at the rate set forth or implicit in the terms of the lease included in such transaction) of the total obligations of the lessee for rental payments (other than amounts required to be paid on account of taxes, maintenance, repairs, insurance, assessments, utilities, operating and labor costs and other items which do not constitute payments for property rights) during the remaining term of the lease included in such Sale/Leaseback Transaction (including any period for which such lease has been extended). In the case of any lease which is terminable by the lessee upon the payment of a penalty, such net amount shall be the lesser of the net amount determined assuming termination upon the first date such lease may be terminated (in which case the net amount shall also include the amount of the penalty, but no rent shall be considered as required to be paid under such lease subsequent to the first date upon which it may be so terminated) or the net amount determined assuming no such termination.
 
“Consolidated Net Tangible Assets” means the total amount of assets (less applicable reserves and other properly deductible items) after deducting (1) all current liabilities (excluding the amount of those which are by their terms extendable or renewable at the option of the obligor to a date more than 12 months after the date as of which the amount is being determined and current maturities of long-term debt) and (2) all goodwill, tradenames, trademarks, patents, unamortized debt discount and expense and other like intangible assets, all as set forth on the most recent quarterly balance sheet of Ensco and its consolidated subsidiaries and determined in accordance with GAAP.
 
“Funded Indebtedness” means all Indebtedness that matures on, or that is renewable at the option of any obligor thereon to, a date more than one year after the date on which such Indebtedness is originally incurred.
 
“Indebtedness” of any Person means, without duplication, (i) all indebtedness of such Person for borrowed money (whether or not the recourse of the lender is to the whole of the assets of such Person or only to a portion thereof), (ii) all obligations of such Person evidenced by bonds, debentures, notes or other similar instruments, (iii) all obligations of such Person in respect of letters of credit or other similar instruments (or reimbursement obligations with respect thereto), other than standby letters of credit, performance bonds and other obligations issued by or for the account of such Person in the ordinary course of business, to the extent not drawn or, to the extent drawn, if such drawing is reimbursed not later than the third Business Day following demand for reimbursement, (iv) all obligations of such Person to pay the deferred and unpaid purchase price of property or services, except trade payables and accrued expenses incurred in the ordinary course of business, (v) all Capitalized Lease Obligations of such Person, (vi) all Indebtedness of


S-8


Table of Contents

others secured by a Lien on any asset of such Person, whether or not such Indebtedness is assumed by such Person (provided that if the obligations so secured have not been assumed in full by such Person or are not otherwise such Person’s legal liability in full, then such obligations shall be deemed to be in an amount equal to the greater of (a) the lesser of (1) the full amount of such obligations and (2) the fair market value of such assets, as determined in good faith by the board of directors of such Person, which determination shall be evidenced by a board resolution, and (b) the amount of obligations as have been assumed by such Person or which are otherwise such Person’s legal liability), and (vii) all Indebtedness of others (other than endorsements in the ordinary course of business) guaranteed by such Person to the extent of such guarantee.
 
“Joint Venture” means any partnership, corporation or other entity, in which up to and including 50% of the partnership interests, outstanding voting stock or other equity interests is owned, directly or indirectly, by Ensco and/or one or more Subsidiaries. A Joint Venture shall not be a Subsidiary.
 
“Lien” means any mortgage, pledge, lien, charge, security interest or similar encumbrance. For purposes of the Indenture, Ensco or any Subsidiary of Ensco shall be deemed to own subject to a Lien any asset which it has acquired or holds subject to the interest of a vendor or lessor under any conditional sale agreement, Capitalized Lease Obligation or other title retention agreement relating to such asset.
 
“Pari Passu Indebtedness” means any Indebtedness of any Person, whether outstanding on the Issue Date of the Notes or thereafter created, incurred or assumed, unless, in the case of any particular Indebtedness, the instrument creating or evidencing the same or pursuant to which the same is outstanding expressly provides that such Indebtedness shall be subordinated in right of payment to the Notes.
 
“Permitted Liens” means (i) Liens existing on the date of the Fourth Supplemental Indenture; (ii) Liens on property or assets of, or any shares of stock of, or other equity interests in, or indebtedness of, any Person existing at the time such Person becomes a Subsidiary of Ensco or at the time such Person is merged into or consolidated with Ensco or any of its Subsidiaries or at the time of a sale, lease or other disposition of the properties of a Person (or a division thereof) as an entirety or substantially as an entirety to Ensco or a Subsidiary; (iii) Liens in favor of Ensco or any of its Subsidiaries; (iv) Liens in favor of governmental bodies to secure progress or advance payments; (v) Liens securing industrial revenue, pollution control or other revenue bonds; (vi) Liens on assets existing at the time of acquisition thereof, securing all or any portion of the cost of acquiring, constructing, improving, developing, expanding or repairing such assets or securing Indebtedness incurred prior to, at the time of, or within 24 months after, the later of the acquisition, the completion of construction, improvement, development, expansion or repair or the commencement of commercial operation of such assets, for the purpose of (a) financing all or any part of the purchase price of such assets or (b) financing all or any part of the cost of construction, improvement, development, expansion or repair of any such assets; (vii) statutory liens or landlords’, carriers’, warehouseman’s, mechanics’, suppliers’, materialmen’s, repairmen’s or other like Liens arising in the ordinary course of business and with respect to amounts not yet delinquent or being contested in good faith by appropriate proceedings; (viii) Liens in connection with legal proceedings or securing tax assessments; (ix) Liens on the stock, partnership or other equity interest of Ensco or any Subsidiary in any Joint Venture or any Subsidiary that owns an equity interest in such Joint Venture to secure Indebtedness, provided the amount of such Indebtedness is contributed and/or advanced solely to such Joint Venture; and (x) any extensions, substitutions, replacements or renewals in whole or in part of a Lien enumerated in clauses (i) through (ix) above.
 
“Principal Property” means any drilling rig or drillship, or integral portion thereof, owned or leased by Ensco or any Subsidiary and used for drilling offshore oil and gas wells, which, in the opinion of the board of directors of Ensco, is of material importance to the business of Ensco and its Subsidiaries taken as a whole, but no such drilling rig or drillship, or portion thereof, shall be deemed of material importance if its net book value (after deducting accumulated depreciation) is less than 2% of Consolidated Net Tangible Assets.
 
“Sale/Leaseback Transaction” means any arrangement with any Person pursuant to which Ensco or any Subsidiary leases any Principal Property that has been or is to be sold or transferred by Ensco or the Subsidiary to such Person, other than (1) temporary leases for a term, including renewals at the option of the lessee, of not more than five years; (2) leases between Ensco and a Subsidiary or between Subsidiaries; and (3) leases of Principal Property executed by the time of, or within 12 months after the latest of, the acquisition,

the completion of construction, alteration, improvement or repair, or the commencement of commercial operation of the Principal Property.
 
“Subsidiary” means a Person at least a majority of the outstanding voting stock of which is owned, directly or indirectly, by Ensco or by one or more other Subsidiaries, or by Ensco and one or more other Subsidiaries. For the purposes of this definition, “voting stock” means stock that ordinarily has voting power for the election of directors, whether at all times or only so long as no senior class of stock has such voting power by reason of any contingency. A Joint Venture shall not be a Subsidiary.
 
Amendment to Pride’s Obligations to Provide SEC Reports
 
The Indenture requires Pride to file with the Trustee, within 15 days after Pride is required to file the same with the SEC, copies of annual reports and of the information, documents and other reports that Pride may be required to file with the SEC pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 or pursuant to Section 314 of the Trust Indenture Act of 1939. As a result of the Merger, when permitted by Section 15(d) of the Securities Exchange Act of 1934, Pride will deregister the Securities. As a result of such deregistration, Pride will no longer be required to file reports with the SEC pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 or pursuant to Section 314 of the Trust Indenture Act of 1939. The deregistration of the Securities will occur regardless of whether the required consents are obtained and proposed amendments are made effective and as a result of such deregistration, Pride will no longer be required to file SEC reports with the Trustee. Therefore, the proposed amendment to the Indenture would replace Pride’s obligation to file such reports pursuant to the Indenture and provide that Ensco will, as the guarantor of the Securities, file with the Trustee, within 15 days after Ensco is required to file the same with the SEC, copies of annual reports and of the information, documents and other reports that Ensco may be required to file with the SEC pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 or pursuant to Section 314 of the Trust Indenture Act of 1939.
 
Addition of Defined Terms and Revision of Other Text
 
In connection with the proposed amendments described above, certain defined terms would be added to, and deleted from, the Indenture. Please see Annex A to this Consent Solicitation/Prospectus Supplement for the text of those amendments. In addition, we reserve the right to make certain technical changes to the Indenture pursuant to the provisions thereof and to include such changes in the supplemental indenture. Any such technical changes will not affect the substantive rights of the holders of the Securities, other than as described above.
 
The proposed amendments would also delete or amend or be deemed to have deleted or amended any provisions in the Securities corresponding to the provisions in the Indenture that are deleted or amended by virtue of the proposed amendments.
 
DESCRIPTION OF ENSCO’S GUARANTEE
 
The following is a summary of the Ensco Guarantee. The following summary is qualified by reference to the full text of the form of the guarantee, which is included in the form of proposed supplemental indenture attached as Annex A to this Consent Solicitation/Prospectus Supplement.
 
The Ensco Guarantee is an unconditional and irrevocable guarantee of the prompt payment, when due, of any amount owed to the holders of the Securities under the Indenture, and any other amounts due pursuant to the Indenture. The Ensco Guarantee will be an unsecured unsubordinated obligation of Ensco and will rank pari passu with Ensco’s other general unsecured obligations. Holders of any secured debt that Ensco may incur in the future may foreclose on the assets securing such debt, reducing the cash flow from the foreclosed property available for payment of unsecured debt, including the Ensco Guarantee. Holders of any secured debt of Ensco also would have priority over unsecured creditors in the event of its bankruptcy, liquidation or similar proceeding. Ensco currently does not have any secured debt outstanding.

Table of Contents

Promptly upon receipt of the required consents, Ensco and Pride will enter into a supplemental indenture that will set forth the amendments to the Indenture. Ensco will execute and deliver the Ensco Guarantee concurrently with the execution of the supplemental indenture. The proposed amendments will become effective after the Merger upon execution and delivery of the supplemental indenture and Ensco’s execution and delivery of the Ensco Guarantee.
 
If the required consents are obtained, all holders of the Securities will be bound by the amended Indenture and all holders of the Securities will receive the Ensco Guarantee pursuant to the terms of the supplemental indenture, even if they have not consented to the proposed amendments. If the required consents are not obtained, the Ensco Guarantee will not be provided to the holders of the Securities.
 
Ensco will execute the Ensco Guarantee in favor of the holders of each series of Securities. It will not be necessary for new certificates to be issued evidencing the Securities to reflect the benefit of the Ensco Guarantee, and no separate certificates will be issued to evidence the Ensco Guarantee.
 
Ensco is not assuming Pride’s obligations under the Indenture. The Ensco Guarantee will not make Ensco or any of its subsidiaries (other than Pride or any successor obligor) subject to the covenants contained in the Indenture and will not otherwise contain any restrictions on Ensco’s operations (other than those that will become effective with respect to Ensco and its Subsidiaries upon effectiveness of the proposed amendments).
 
CONSENT PROCEDURES
 
Expiration Time; Extension; Waiver; Amendment; Termination
 
The consent solicitation will expire at 5:00 p.m., New York City time, on Friday, May 27, 2011, unless Ensco extends the consent solicitation. Ensco expressly reserves the right to extend the consent solicitation from time to time or for such period or periods as it may determine in its discretion by giving oral (to be confirmed in writing) or written notice of such extension to the Solicitation Agent and by making a public announcement by press release at or prior to 9:00 a.m., New York City time, on the next business day following the previously scheduled expiration time. During any extension of the consent solicitation, all consents validly executed and delivered to the Solicitation Agent will remain effective unless validly revoked prior to such extended expiration time.
 
Ensco expressly reserves the right, in its sole discretion, at any time to amend any of the terms of the consent solicitation. If the terms of the consent solicitation are amended prior to the Expiration Time in a manner that constitutes a material change, Ensco will promptly give oral (to be confirmed in writing) or written notice of such amendment to the Solicitation Agent and disseminate a Consent Solicitation/Prospectus Supplement in a manner reasonably designed to give holders of the Securities notice of the change on a timely basis. Ensco expressly reserves the right, in its discretion, to waive any condition of the consent solicitation.
 
Ensco expressly reserves the right, in its discretion, to terminate the consent solicitation for any reason. Any such termination will be followed promptly by public announcement thereof. In the event Ensco terminates the consent solicitation, it will give prompt notice thereof to the Solicitation Agent and the consents previously executed and delivered pursuant to the consent solicitation will be of no further force and effect.
 
Procedures for Delivering Consents
 
In order to consent to the proposed amendments, a holder of the Securities must deliver a Bondholder Ballot to the address stated on the ballot before the Expiration Time.
 
Giving a consent by submitting a Bondholder Ballot will not affect a holder’s right to sell or transfer its Securities. All consents received from the holder of record on the Record Date, and not revoked by that holder before the Revocation Time, will be effective notwithstanding any transfer of those Securities after the Record Date.


S-11


Table of Contents

All Bondholder Ballots that are properly completed, executed and delivered to the address on the ballot, and not revoked before the Expiration Time, will be given effect in accordance with the terms of those Bondholder Ballots.
 
In connection with the consent solicitation, Ensco will pay brokerage houses and other custodians, nominees and fiduciaries the reasonable out-of-pocket expenses incurred by them in forwarding copies of this Consent Solicitation/Prospectus Supplement, the Bondholder Ballot and related documents to the beneficial owners of the Securities and in handling or forwarding deliveries of consents by their customers.
 
All questions as to the validity, form and eligibility (including time of receipt) of Bondholder Ballot and the consent procedures will be determined by Ensco, in its sole discretion, which determination will be final and binding. Ensco also reserves the right to waive any defects or irregularities as to deliveries of consents.
 
Revocation of Consents
 
A consent may be revoked at any time prior to the Revocation Time. Any holder who has delivered a consent, or who succeeds to ownership of Securities in respect of which a consent has previously been delivered, may validly revoke such consent prior to the Revocation Time by delivering a written notice of revocation in accordance with the following procedures. All properly completed and executed Bondholder Ballots that are received by the Information and Tabulation Agent will be counted as consents with respect to the proposed amendments, unless the Trustee and the Information and Tabulation Agent receives a written notice of revocation prior to the Revocation Time.
 
In order to be valid, a notice of revocation of consent must contain the name of the person who delivered the consent, the name of the holder and the description and CUSIP Number of the Securities to which it relates, the certificate numbers of such Securities (if held in certificated form) and the aggregate principal amount represented by such Securities. The revocation of consent must be signed by the holder thereof in the same manner as the original signature on the Bondholder Ballot or be accompanied by evidence satisfactory to Ensco, the Trustee and the Information and Tabulation Agent that the person revoking the consent has the legal authority to revoke such consent on behalf of the holder. If the Bondholder Ballot was executed by a person other than the registered holder of the Securities, the notice of revocation of consent must be accompanied by a valid proxy signed by such registered holder and authorizing the revocation of the registered holder’s consent. To be effective, a revocation of consent must be received prior to the Revocation Time by the Information and Tabulation Agent, at the address set forth below. A purported notice of revocation that lacks any of the required information or is sent to an improper address will not validly revoke a consent previously given. Holders who hold their Securities through a bank, broker or other financial institution may only revoke consents in the manner prescribed by such bank, broker or other financial institution. Therefore, please follow the instructions provided by the applicable bank, broker or other financial institution if revoking consents.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES
 
The following is a general summary of the material U.S. federal income tax consequences of the implementation of the proposed amendments to the Indenture and the provision of the Ensco Guarantee (collectively, the “Transactions”). This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations promulgated thereunder (the “Treasury Regulations”), and currently effective administrative rulings and judicial decisions. Any of these authorities may be changed, perhaps with retroactive effect, so as to result in U.S. federal income tax consequences different from those described below. No ruling from the Internal Revenue Service (the “IRS”) has been (or will be) sought with respect to the statements made herein, and there can be no assurance that the IRS will not take a position contrary to such statements or that a court will not sustain any such contrary position taken by the IRS. This summary assumes that the Securities are held as capital assets. In addition, this summary is not a complete analysis of all the potential tax considerations relating to the Transactions, including those considerations applicable to holders based on their particular circumstances, and does not address the tax consequences applicable to holders that are subject to special tax rules, including holders subject to the alternative minimum tax; banks, insurance companies, or other financial institutions; controlled foreign corporations or their shareholders; passive foreign investment companies or their shareholders; tax-exempt organizations; retirement plans; individual retirement accounts; tax-deferred accounts; dealers in securities or commodities; expatriates; traders in securities that elect to use a mark-to-market method of accounting for their securities holdings; U.S. Holders (as defined below) whose functional currency is not the U.S. dollar; persons that hold Securities as part of a hedge, straddle, conversion transaction or other integrated transaction; regulated investment companies; real estate investment trusts; persons deemed to sell Securities under the constructive sale provisions of the Code; or partnerships or other pass-through entities. This summary does not address any foreign, state or local tax consequences of the Transactions. If a partnership (or entity treated as a partnership for U.S. federal income tax purposes) is the beneficial owner of Securities, the tax treatment of a partner in such partnership will generally depend upon the status of the partner and the activities of the partnership. A partner of a partnership holding Securities is urged to consult its own tax advisor regarding the tax consequences of the Transactions.
 
For purposes of this summary, a holder of a Security is a “U.S. Holder” if such holder is the beneficial owner of a Security and is: (1) an individual who is a citizen or resident of the United States, including an alien individual who is a lawful permanent resident of the United States or meets the substantial presence test under section 7701(b) of the Code; (2) a corporation (or entity treated as a corporation for U.S. federal income tax purposes) created or organized, or treated as created or organized, in or 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 tax regardless of its source; or (4) a trust (a) if a U.S. court can exercise primary supervision over the trust’s administration and one or more United States persons are authorized 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 U.S. person. The term “Non-U.S. Holder” means a beneficial owner of a Security that is neither a U.S. Holder nor a partnership for U.S. federal income tax purposes.
 
THIS SUMMARY OF MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE TRANSACTIONS IS INCLUDED HEREIN FOR GENERAL INFORMATION ONLY AND DOES NOT CONSTITUTE, AND IS NOT A SUBSTITUTE FOR, PROFESSIONAL TAX ADVICE. HOLDERS OF SECURITIES ARE URGED TO CONTACT THEIR OWN TAX ADVISORS REGARDING THE U.S. FEDERAL, STATE AND LOCAL AND FOREIGN TAX CONSEQUENCES OF THE TRANSACTIONS TO THE APPLICABLE HOLDER.
 
U.S. Holders
 
The modification of the terms of a debt instrument generally is treated as a “deemed” exchange of an “old” debt instrument for a “new” debt instrument if such modification is “significant” as specially determined for U.S. federal income tax purposes. For these purposes, a modification of the terms of a debt instrument is generally “significant” if, based on all the facts and circumstances (and, subject to certain exceptions, taking into account all modifications collectively), the legal rights or obligations that are altered and the degree to


S-13

which they are altered are economically significant. Ensco believes that the adoption of the proposed amendments to the Indenture should not constitute such an economically significant change in the terms of the Securities. Upon adoption of the proposed amendments, Ensco will guarantee Pride’s payment obligations with respect to the Securities. The Treasury Regulations provide that the addition of a guarantor on a debt instrument is a significant modification if the addition of the guarantor results in a change in payment expectations (as specifically defined pursuant to such Treasury Regulations) with respect to the instrument. Ensco believes that the Ensco Guarantee should not result in a change in payment expectations with respect to the Securities. Accordingly, U.S. Holders of Securities generally should not recognize gain or loss on the Securities as a result of the Transactions and should continue to have the same tax basis and holding period with respect to the Securities as they had before the Transactions. Holders are urged to consult their own tax advisors to determine whether the Transactions result in a significant modification for purposes of the applicable holder’s Securities.
 
If, notwithstanding the foregoing, the Transactions result in a significant modification of some or all of the Securities for U.S. federal income tax purposes, a U.S. Holder of such Securities generally would be treated as having exchanged its “old” Securities for “new” Securities for U.S. federal income tax purposes, and generally would recognize gain or loss at the time of such deemed exchange, unless such deemed exchange constitutes a recapitalization. A deemed exchange generally would constitute a recapitalization and would not be taxable to U.S. Holders of the Securities if the instruments, as originally issued and as amended, constitute “securities” for U.S. federal income tax purposes. There is no precise definition of what constitutes a “security” under U.S. federal income tax law, and the determination requires an overall evaluation of the nature of the debt instrument, with the term of the debt instrument regarded as one of the more important factors. Although the matter is not free from doubt, given the terms of the Securities, these instruments generally should constitute “securities” for U.S. federal income tax purposes, and a deemed exchange generally should constitute a recapitalization for such purposes. In such event, a U.S. Holder of a Security generally would not recognize any income, gain or loss as a result of the Transactions. Assuming a deemed exchange constitutes a recapitalization, a U.S. Holder generally would receive a tax basis in the “new” Security equal to its tax basis in the “old” Security immediately prior to the “deemed” exchange, and the U.S. Holder’s holding period for the “new” Security generally would include the period during which the U.S. Holder held the “old” Security.
 
Additionally, if there is a deemed exchange, regardless of whether such exchange qualifies as a recapitalization, the “new” Securities generally would be treated as issued with original issue discount (“OID”) in an amount equal to the excess, if any (subject to a statutorily defined de minimis exception), of the stated redemption price at maturity of the “new” Securities over their issue price. A U.S. Holder that is deemed to hold “new” Securities with OID generally would be required to include the OID in gross income under a constant yield method in advance of the receipt of cash attributable to that income, regardless of the holder’s method of tax accounting. OID accruals may be reduced by a portion of the acquisition premium, if any, that a U.S. Holder has in the “new” Securities. A U.S. Holder has “acquisition premium” in the “new” Securities if the holder’s adjusted tax basis in the “new” Securities is greater than the issue price of the “new” Securities, but less than or equal to their stated redemption price at maturity. If a U.S. Holder’s adjusted tax basis in the “new” Securities exceeds its stated redemption price at maturity, the U.S. Holder will be considered to have acquired the “new” Securities” with “amortizable bond premium” and such U.S. Holder will not be required to include any OID in income. A U.S. Holder generally may elect to amortize any amortizable bond premium over the remaining term of the “new” Securities on a constant yield method as an offset to interest otherwise includible in income under the U.S. Holder’s regular accounting method. If the U.S. Holder does not elect to amortize any amortizable bond premium, that amortizable bond premium will decrease the gain or increase the loss a U.S. Holder otherwise would recognize on disposition of the “new” Securities.
 
Non-U.S. Holders
 
Even if the Transactions result in a deemed exchange of “old” Securities for “new” Securities that is taxable to U.S. Holders, a Non-U.S. Holder generally would not be subject to U.S. federal income tax with


S-14


Table of Contents

respect to income or gain recognized in the Transactions, unless (1) such income or gain is effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, in the case of an applicable income tax treaty, is attributable to a U.S. permanent establishment maintained by the Non-U.S. Holder), or (2) in the case of a Non-U.S. Holder that is a non-resident alien individual, such Non-U.S. Holder is present in the United States for at least 183 days in the year of the deemed exchange, and certain other conditions are met. A corporate Non-U.S. Holder’s income or gain that is effectively connected with the conduct of a trade or business within the United States may be subject to an additional “branch profits” tax at a 30% rate (or a lower rate if specified by an applicable income tax treaty).
 
MATERIAL U.K. TAX CONSEQUENCES
 
The following discussion is intended to be a general summary as to the material U.K. tax consequences of the Transactions based on current U.K. tax law and H.M. Revenue & Customs (“HMRC”) practice applying as of the date of this prospectus supplement, both of which are subject to change at any time, possibly with retrospective effect or to different interpretations. The following discussion relates only to the position of persons who are absolute beneficial owners of the notes and do not deal with the position of certain classes of holders such as dealers, employees or directors of Ensco plc or its affiliates, persons who are connected with Ensco plc, insurance companies, charities, collective investment schemes, pension schemes or persons who hold the Securities other than as an investment. The following discussion is not a complete discussion of all the potential tax consequences of the Transactions that may be relevant to you. We cannot assure you that HMRC will not challenge one or more of the tax consequences described in this prospectus supplement. We have not obtained, nor do we intend to obtain, a ruling from the HMRC with respect to the U.K. tax consequences of the Transactions. It is recommended that all holders of Securities obtain their own taxation advice.
 
For purposes of this summary, a holder of a Security is a “U.K. Holder” if such holder is the beneficial owner of a Security and is: (1) an individual who is resident or ordinary resident in the U.K.; (2) an individual who is not resident or ordinarily resident in the U.K. but who carries on a trade in the U.K. through a branch or agency in the UK to which the Securities are attributable; (3) a company which is resident in the U.K.; or (4) a company which is not resident in the U.K. but which carries on a trade in the U.K. through a permanent establishment in the U.K. to which the Securities are attributable. We do not consider the treatment of other persons or entities which are resident in the U.K. or carry on a trade in the U.K. and which may be within the charge to income tax or corporation tax in the U.K. For the purposes of this summary, a holder of a Security is a “Non-U.K. Holder” if such person or entity is neither resident nor ordinarily resident in the U.K. and does not carry on a trade in the U.K.
 
U.K. Holders and non-U.K. Holders
 
The adoption of the proposed amendments to the Indenture should not have U.K. consequences for U.K. Holders or non-U.K. Holders of the Securities.
 
Guarantee Payments
 
If Ensco plc in its capacity as Guarantor under the amended Indenture makes any payments in respect of interest on any of the Securities (or other amounts due under the Securities other than repayments of amounts subscribed for the Securities) such payments may be subject deduction of UK withholding tax at source at the basic rate (currently 20 per cent.), subject to such relief as may be available under the provisions of any applicable double taxation treaty or any other exemption which may apply.
 
This discussion is for general purposes only. You should consult your own tax advisor as to the particular U.K. tax consequences to you of the Transactions, including the effect and applicability of local or foreign tax laws or tax treaties and the possible effects of changes in the tax law.

With respect to the unaudited interim financial information of Ensco plc for the periods ended March 31, 2011 and 2010, incorporated by reference herein, the independent registered public accounting firm has reported that they applied limited procedures in accordance with professional standards for a review of such information.

The independent registered public accounting firm is not subject to the liability provisions of Section 11 of the Securities Act of 1933 (the “1933 Act”) for their report on the unaudited interim financial information of Ensco plc because that report is not a “report” or a “part” of the registration statement prepared or certified by the independent registered public accounting firm within the meaning of Sections 7 and 11 of the 1933 Act.

Ensco shall not, and shall not permit any of its Subsidiaries to, issue, assume or guarantee any Indebtedness for borrowed money secured by any Lien upon any Principal Property or any shares of stock or Indebtedness of any Subsidiary that owns or leases a Principal Property (whether such Principal Property, shares of stock or Indebtedness are now owned or hereafter acquired) without making effective provision whereby the Notes (together with, if Ensco shall so determine, any other Indebtedness or other obligation of Ensco or any Subsidiary) shall be secured equally and ratably with (or, at the option of Ensco, prior to) the Indebtedness so secured for so long as such Indebtedness is so secured. The foregoing restrictions will not, however, apply to Indebtedness secured by Permitted Liens.
 
Notwithstanding the foregoing, Ensco and its Subsidiaries may, without securing the Notes, issue, assume or guarantee Indebtedness that would otherwise be subject to the foregoing restrictions in an aggregate principal amount that, together with all other such Indebtedness of Ensco and its Subsidiaries that would otherwise be subject to the foregoing restrictions (not including Indebtedness permitted to be secured under the definition of Permitted Liens) and the aggregate amount of Attributable Indebtedness deemed outstanding with respect to Sale/Leaseback Transactions (other than Sale/Leaseback Transactions in connection with which Ensco has voluntarily retired any of the Securities, any Pari Passu Indebtedness or any Funded Indebtedness pursuant to Section 4.09(c)) does not at any one time exceed 15% of Consolidated Net Tangible Assets.

Section 4.09  Limitation on Sale/Leaseback Transactions
 
Ensco shall not, and shall not permit any Subsidiary to, enter into any Sale/Leaseback Transaction with any Person (other than Ensco or a Subsidiary) unless:
 
(a) Ensco or such Subsidiary would be entitled to incur Indebtedness in a principal amount equal to the Attributable Indebtedness with respect to such Sale/Leaseback Transaction secured by a Lien on the property subject to such Sale/Leaseback Transaction pursuant to Section 4.08 without equally and ratably securing the Notes, pursuant to Section 4.08;
 
(b) after the date of the Fourth Supplemental Indenture and within a period commencing nine months prior to the consummation of such Sale/Leaseback Transaction and ending nine months after such consummation, Ensco or any Subsidiaries shall have expended for property used or to be used in the ordinary course of business of Ensco and its Subsidiaries an amount equal to all or a portion of the net proceeds of such Sale/Leaseback Transaction and Ensco shall have elected to designate such amount as a credit against such Sale/Leaseback Transaction (with any such amount not being so designated to be applied as set forth in clause (c) below or as otherwise permitted); or
 
(c) Ensco, during the nine-month period after the effective date of such Sale/Leaseback Transaction, shall have applied to the voluntary defeasance or retirement of any Securities, any Pari Passu Indebtedness or any Funded Indebtedness an amount equal to the greater of the net proceeds of the sale or transfer of the property leased in such Sale/Leaseback Transaction and the fair value, as determined by the Board of Directors of Ensco and evidenced by a Board Resolution, of such property at the time of entering into such Sale/Leaseback Transaction (in either case adjusted to reflect the remaining term of the lease and any amount expended by the Company as set forth in clause (b) above).

Exhibit A
 
FORM OF PARENT GUARANTEE
 
GUARANTEE, dated as of          , 2011, by Ensco plc, an English public limited company (the “Guarantor”), in respect of Pride International, Inc, a Delaware corporation (together with its permitted assigns, “Pride”).
 
1. Guarantee.  With respect to the 8.500% Senior Notes due 2019; 6.875% Senior Notes due 2020; and 7.875% Senior Notes due 2040 (collectively called the “Notes”), all issued by Pride pursuant to an indenture dated July 1, 2004 (the “Indenture”), by and among Pride and The Bank of New York Mellon, as successor to JPMorgan Chase Bank, N.A., as trustee (“Trustee”), the Guarantor unconditionally and irrevocably guarantees the prompt payment, when due, of any amount owed to the holders of the Notes under the Indenture and any other amounts due pursuant to the Indenture (the “Obligations”).
 
2. Nature of Guarantee.  The Guarantor’s obligations hereunder shall not be affected by any circumstance relating to the Obligations that might otherwise constitute a legal or equitable discharge of or defense to the Guarantor. The Guarantor agrees that Trustee or the holders of the Notes may resort to the Guarantor for payment of any of the Obligations whether or not Trustee or the holders of the Notes shall have first proceeded against Pride or any other obligor principally or secondarily obligated with respect to the Obligations. Trustee or the holders of the Notes shall not be obligated to file any claim relating to the Obligations in the event that Pride becomes subject to a bankruptcy, reorganization or similar proceeding, and the failure of Trustee or the holders of the Notes to so file shall not affect the Guarantor’s obligations hereunder. In the event that any payment to Trustee or the holders of the Notes in respect of the Obligations is rescinded or must otherwise be returned for any reason whatsoever, the Guarantor shall remain liable hereunder with respect to such Obligations as if such payment had not been made.
 
3. Changes in Obligations, and Agreements Relating thereto; Waiver of Certain Notices.  The Guarantor agrees that Trustee or the holders of the Notes may at any time and from time to time, either before or after the maturity thereof, without notice to or further consent of the Guarantor, extend the time of payment of, or renew all or any part of the Obligations, and may also make any agreement with Pride for the extension, renewal, payment, compromise, discharge or release thereof, in whole or in part, or for any modification of the terms thereof or of any agreement between Trustee or the holders of the Notes and Pride, without in any way impairing or affecting this Guarantee. The Guarantor waives notice of the acceptance of this Guarantee and of the Obligations, presentment, demand for payment, notice of dishonor and protest.
 
4. Expenses.  The Guarantor agrees to pay on demand all reasonable fees and out-of-pocket expenses (including the reasonable fees and expenses of one firm of counsel representing Trustee or the holders of the Notes) in any way relating to the enforcement or protection of the rights of Trustee or the holders of the Notes hereunder, provided that the Guarantor shall not be liable for any expenses of Trustee or the holders of the Notes if no payment under this Guarantee is due.
 
5. Subrogation.  Upon payment of the Obligations to Trustee or the holders of the Notes in full, the Guarantor shall be subrogated to the rights of Trustee or the holders of the Notes against Pride with respect to the Obligations, and Trustee or the holders of the Notes agrees to take at the Guarantor’s expense such steps as the Guarantor may reasonably request to implement such subrogation.
 
6. No Waiver; Cumulative Rights.  No failure on the part of Trustee or the holders of the Notes to exercise, and no delay in exercising, any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by Trustee or the holders of the Notes of any right, remedy or power hereunder preclude any other or further exercise of any right, remedy or power. Each and every right, remedy and power hereby granted to Trustee and the holders of the Notes or allowed it or them by law or in equity or other agreement shall be cumulative and not exclusive of any other, and may be exercised by Trustee or the holders of the Notes at any time or from time to time.

7. Assignment.  Nothing contained in this Guarantee shall prevent any consolidation or merger of Guarantor with or into any other Person (whether or not affiliated with the Guarantor), or successive consolidations or mergers in which Guarantor or its successor shall be a party or parties, or shall prevent any conveyance or transfer of the properties and assets of Guarantor as an entirety or substantially as an entirety to any other Person (whether or not affiliated with Guarantor) lawfully entitled to acquire the same; provided, however, that upon any such consolidation, merger, conveyance or transfer, the due and punctual performance and observance of all of the covenants and conditions of the Guarantee to be performed by Guarantor, shall be expressly assumed, in form reasonably satisfactory to the Trustee, executed and delivered to the Trustee by the Person (if other than the Guarantor) formed by such consolidation, or into which Guarantor shall have been merged, or by the Person which shall have acquired such properties and assets.
 
8. Notices.  Any notice or communication to the Guarantor is duly given if in writing and delivered in person or mailed by first-class mail (registered or certified, return receipt requested), telex, facsimile or overnight air courier guaranteeing next day delivery, to the following address:

London, England W1J 5BQ
Tel: +44 (0) 20 7659 4660
 
The Guarantor by notice to the Trustee may designate additional or different addresses for subsequent notices or communications.
 
9. Continuing Guarantee.  This Guarantee shall remain in full force and effect and shall be binding on the Guarantor, its successors and assigns until all of the Obligations have been satisfied in full.
 
10. Representations and Warranties.  The Guarantor represents and warrants that: (i) this Guarantee has been duly executed and delivered by the Guarantor and constitutes a valid and legally binding obligation of the Guarantor enforceable in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally and subject to general principles of equity, (ii) no consent or approval of any Person, entity or governmental or regulatory authority, or of any securities exchange or self-regulatory organization, was or is necessary in connection with this Guarantee and (iii) the execution and delivery of this Guarantee by the Guarantor and the performance by the Guarantor of its obligations hereunder do not violate or conflict with any law applicable to it, any provision of its constitutive documents, any order or judgment of any court or other agency of government applicable to it or any of its assets or any contractual provision binding on or affecting it or any of its assets, in any manner that could reasonably be expected to impair its ability to perform its obligations hereunder.
 
11. Governing Law.  This Guarantee shall be governed by and construed in accordance with the laws of the State of New York without regard to principles of conflicts of laws.
 
IN WITNESS WHEREOF, this Guarantee has been duly executed and delivered by the Guarantor as of the date first above written.

THE INFORMATION CONTAINED IN OUR WEBSITE IS NOT INCORPORATED BY REFERENCE AND DOES NOT CONSTITUTE A PART OF THIS PROSPECTUS.
 
FORWARD LOOKING INFORMATION
 
The information contained in this Prospectus is accurate only as of the date hereof.
 
This Prospectus and documents incorporated herein by reference contain some forward looking statements that set forth anticipated results based on management’s plans and assumptions. From time to time, we also provide forward looking statements in other materials we release to the public, as well as oral forward looking statements. Such statements give our current expectations or forecasts of future events; they do not relate strictly to historical or current facts. We have tried, wherever possible, to identify such statements by using words such as “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” “will,” “target”, “forecast” and similar expressions in connection with any discussion of future operating or financial performance or business plans or prospects. In particular, these include statements relating to future actions, business plans and prospects, future performance or results of current and anticipated products, expenses, interest rates, foreign exchange rates, the outcome of contingencies, such as legal proceedings, and financial results.
 
We cannot guarantee that any forward looking statement will be realized. Achievement of future results is subject to risks, uncertainties and potentially inaccurate assumptions. Should known or unknown risks or uncertainties materialize, or should underlying assumptions prove inaccurate, actual results could differ materially from past results and those anticipated, estimated or projected. You should bear this in mind as you consider forward looking statements.
 
You should take care not to place undue reliance on forward looking statements, which represent our views only as of the date they are made. We undertake no obligation to publicly update forward looking statements, whether as a result of new information, future events or otherwise. You are advised, however, to consult any further disclosures we make on related subjects in our Quarterly Reports on Form 10-Q and Current Reports on Form 8-K filed with the SEC. Also note that we provide cautionary discussion of risks, uncertainties and possibly inaccurate assumptions relevant to our businesses and the proposed merger with Pride International, Inc. in our Annual Report on Form 10-K for the year ended December 31, 2010, and our most recently filed Quarterly Reports on Form 10-Q, and any amendments thereto, and our Registration Statement on Form S-4, which was declared effective by the SEC on April 25, 2011. These are factors that, individually or in the aggregate, may cause our actual results to differ materially from expected and historical results. We note these factors for investors as permitted by the Private Securities Litigation Reform Act of 1995. You should understand that it is not possible to predict or identify all such factors. Consequently, you should not consider those factors to be a complete discussion of all potential risks or uncertainties.

RISK FACTORS
 
Investing in our securities involves significant risks. Before making an investment decision, you should carefully consider the risks and other information we include or incorporate by reference in this prospectus. In particular, you should consider the risk factors set forth in our most recent Annual Report on Form 10-K filed with the SEC, as those risk factors are amended or supplemented by subsequent Quarterly Reports on Form 10-Q. The risks and uncertainties we have described are not the only ones facing us. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business operations. Additional risk factors may be included in a prospectus supplement relating to a particular series or offering of securities.
 
THE COMPANY
 
Ensco plc is an English public limited company formed in 2009 in connection with our redomestication from Delaware to England. Our predecessor, ENSCO International Incorporated, was formed as a Texas corporation in 1975 and reincorporated in Delaware in 1987. In connection with our redomestication to England, each issued and outstanding share of common stock of ENSCO International Incorporated was converted into the right to receive one American depositary share (“ADS”), each representing one Class A ordinary share, nominal value $0.10 per share, of Ensco plc.
 
We are a global offshore contract drilling company. As of March 31, 2011, our offshore rig fleet included 40 jackup rigs, five ultra-deepwater semisubmersible rigs and one barge rig. Additionally, we have three ultra-deepwater semisubmersible rigs under construction and recently announced that we have ordered the construction of two new ultra-premium, harsh environment jackup rigs. We are one of the leading providers of offshore contract drilling services to the international oil and gas industry. Our customers include major integrated oil and natural gas companies, state-owned national oil companies and independent oil and natural gas companies. Our operations are concentrated in the geographic regions of Asia Pacific (which includes Asia, the Middle East and Australia), Europe and Africa, and North and South America.
 
Our ADSs are listed on the NYSE and trade under the symbol “ESV.”
 
On February 6, 2011, Ensco plc entered into an Agreement and Plan of Merger with Pride International, Inc., a Delaware corporation (“Pride”), ENSCO International Incorporated, a Delaware corporation and a wholly-owned subsidiary and predecessor of Ensco, and ENSCO Ventures LLC, a Delaware limited liability company and an indirect, wholly-owned subsidiary of Ensco (“Merger Sub”). Pursuant to the merger agreement and subject to the conditions set forth therein, Merger Sub will merge with and into Pride, with Pride as the surviving entity and an indirect, wholly-owned subsidiary of Ensco (the “Merger”).
 
Our registered office and principal executive offices are located at 6 Chesterfield Gardens, London, England W1J 5BQ and its telephone number is +44 (0) 20 7659 4660.
 
USE OF PROCEEDS
 
We intend to use the net proceeds from the sales of the securities for general corporate purposes unless otherwise set forth in the applicable prospectus supplement.
 
RATIO OF EARNINGS TO FIXED CHARGES
 
For the purpose of computing the ratio of earnings to fixed charges, “earnings” consist of income from continuing operations before income taxes, fixed charges and amortization of capitalized interest, less income from continuing operations before income taxes attributable to noncontrolling interests and interest capitalized. “Fixed charges” consist of interest expensed and capitalized and estimates of interest within rental expense. The ratios were calculated by dividing the sum of the fixed charges into the sum of the earnings. The following ratios do not reflect the Merger. Our consolidated ratio of earnings to fixed charges for each of the

Our unsecured senior debt securities will be issued under an indenture to be entered into by us and Deutsche Bank Trust Company Americas or another trustee to be named in a prospectus supplement. The unsecured senior subordinated debt securities will be issued under a separate indenture to be entered into by us and Deutsche Bank Trust Company Americas or another trustee to be named in a prospectus supplement. The unsecured subordinated debt securities will be issued under a separate indenture to be entered into by us and Deutsche Bank Trust Company Americas or another trustee to be named in a prospectus supplement.
 
A form of senior debt indenture is filed as an exhibit to the registration statement of which this prospectus is a part and is incorporated by reference into this prospectus. Forms of the senior subordinated debt indenture and the subordinated debt indenture are filed as exhibits to the registration statement of which this prospectus is a part and are incorporated by reference into this prospectus. You should refer to the applicable indenture for more specific information.
 
The senior debt securities will rank equally with each other and with all of our other unsecured and unsubordinated indebtedness. Our senior debt securities will effectively be subordinated to our secured indebtedness, including amounts we have borrowed under any secured revolving or term credit facility and ship mortgages or bonds, and the liabilities of our subsidiaries. The senior subordinated debt securities will be subordinate and junior in right of payment, as more fully described in an indenture and in any applicable supplement to the indenture, to the senior indebtedness designated in such indenture or supplemental indenture. The subordinated debt securities will be subordinate and junior in right of payment, as more fully described in an indenture and in any applicable supplement to the indenture, to all of our senior and senior subordinated indebtedness.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
The consolidated financial statements of Ensco plc and subsidiaries as of December 31, 2010 and 2009, and for each of the years in the three-year period ended December 31, 2010, and management’s assessment of the effectiveness of internal control over financial reporting as of December 31, 2010 have been incorporated herein in reliance upon the reports of KPMG LLP, independent registered public accounting firm, and upon the authority of said firm as experts in accounting and auditing.
 
With respect to the unaudited interim financial information of Ensco plc for the periods ended March 31, 2011 and 2010, incorporated by reference herein, the independent registered public accounting firm has reported that they applied limited procedures in accordance with professional standards for a review of such information. However, their separate report included in Ensco’s quarterly report on Form 10-Q for the quarter ended March 31, 2011, and incorporated by reference herein, states that they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. The independent registered public accounting firm is not subject to the liability provisions of Section 11 of the Securities Act of 1933 (the “1933 Act”) for their report on the unaudited interim financial information of Ensco plc because that report is not a “report” or a “part” of the registration statement prepared or certified by the independent registered public accounting firm within the meaning of Sections 7 and 11 of the 1933 Act.
