Item 8.01 Other Events

On February 6, 2011, Pride entered into a merger agreement with Ensco plc and two of its subsidiaries. Pursuant to the merger agreement and subject to the conditions provided in the agreement, Pride will merge with one of the subsidiaries and become an indirect, wholly owned subsidiary of Ensco. On April 26, 2011, Pride filed with the SEC a definitive joint proxy statement/prospectus of Ensco and Pride in connection with the proposed merger. Pride is providing certain additional disclosure that supplements disclosure contained in the joint proxy statement/prospectus. These additional disclosures should be read in conjunction with the disclosures contained therein. To the extent that information in this Current Report on Form 8-K differs from or updates information contained in the joint proxy statement/prospectus, this Current Report on Form 8-K is more current. Capitalized terms used but not defined in the additional disclosures have the meanings given them in the joint proxy statement/prospectus.

Additional Disclosure Regarding the Opinion of Goldman, Sachs & Co.

The first paragraph on Page 83 of the joint proxy statement/prospectus under the caption “The Merger—Opinion of Goldman, Sachs & Co.—Summary of Financial Analyses of Pride’s Financial Advisor— Historical Exchange Ratio Analysis” is supplemented to read as set forth below. The new text is underlined.

Historical Exchange Ratio Analysis. Goldman Sachs calculated the average historical exchange ratios of Pride common stock to Ensco ADSs based on the closing prices of Pride common stock and Ensco ADSs during the 30-trading day, 60-trading day, 90-trading day, one-year, three-year and five-year periods ended February 4, 2011, as well as the exchange ratio of the closing prices of Pride common stock to Ensco ADSs on February 4, 2011. This analysis provides a perspective on the relative closing prices of Pride common stock and Ensco ADSs during various historical periods in view of Ensco ADSs constituting a substantial portion of the total consideration being paid by Ensco in the transaction. The following table presents the results of this analysis:

The section captioned “The Merger—Opinion of Goldman, Sachs & Co.—Summary of Financial Analyses of Pride’s Financial Advisor—Relative Discounted Cash Flow Analysis” beginning on page 83 of the joint proxy statement/prospectus is supplemented to read as set forth below. The new text is underlined.

Relative Discounted Cash Flow Analysis. Goldman Sachs performed an illustrative relative discounted cash flow analysis to determine the implied net present value per share of Pride common stock, the implied net present value per Ensco ADS and the implied exchange ratio of Pride common stock to Ensco ADSs, assuming each company continued to operate as a standalone company, using the Base Case Forecasts for Pride and Ensco.

In its analysis Goldman Sachs applied a range of illustrative discount rates for each of Pride and Ensco ranging from 9% to 13%, derived by utilizing the capital asset pricing model, which takes into account certain financial metrics, including betas, for Pride and Ensco, as well as certain financial metrics for the United States financial markets generally, to the projected cash flows (beginning January 1, 2011 and discounted using the mid-year convention) generated by Pride’s and Ensco’s assets over their estimated remaining lives. This analysis resulted in a range of implied exchange ratios of 0.46x to 0.51x. This analysis resulted in a range of implied net present values per share of Pride common stock of $23.52 to $38.44 and per Ensco ADS of $51.69 to $75.62.

Goldman Sachs also performed the same analysis as in the paragraph above based upon the same assumptions, except that in this analysis Goldman Sachs applied a range of discount rates for Pride ranging from 9% to 13% and applied a range of discount rates for Ensco equal to 100 basis points higher than the corresponding discount rate for Pride. This analysis resulted in a range of implied exchange ratios of 0.49x to 0.56x. Based on a range of illustrative discount rates of 9% to 13% for each of Pride and Ensco, this analysis resulted in a range of implied net present values per share of Pride common stock of $23.52 to $38.44 and per Ensco ADS of $51.69 to $75.62.

Goldman Sachs also calculated implied exchange ratios of Pride common stock to Ensco ADSs using present values of estimated cash flows for Pride and Ensco through the year 2015 and present values of an illustrative terminal value of Pride and Ensco at the end of year 2015, based on a range of multiples for Ensco of 3.0x to 11.0x estimated 2016 EBITDA and a range of multiples for Pride of the corresponding multiple for Ensco plus 0.0x to 2.0x, assuming an illustrative discount rate of 11%. The enterprise value to forward year EBITDA multiple range used by Goldman Sachs in this analysis was derived by Goldman Sachs utilizing its experience and professional judgment, taking into account current and historical trading data and the current and historical enterprise value to forward year EBITDA multiples for Pride, Ensco and the Selected Companies referenced in “— Opinion of Goldman, Sachs & Co.—Summary of Financial Analyses of Pride’s Financial Advisor—Selected Companies Analysis” above. This analysis resulted in a range of implied exchange ratios of 0.36x to 0.62x. Based on a range of multiples for Pride of 4.0x to 12.0x estimated 2016 EBITDA and a range of multiples for Ensco of 3.0x to 11.0x estimated 2016 EBITDA, this analysis resulted in a range of implied net present values per share of Pride common stock of $15.84 to $45.48 and per Ensco ADS of $33.65 to $79.93.

Goldman Sachs also calculated implied exchange ratios of Pride common stock to Ensco ADSs using present values of estimated cash flows for Pride and Ensco through the year 2015 and present values of an illustrative terminal value of Pride and Ensco at the end of year 2015, based on a range of multiples for Ensco of 3.0x to 11.0x estimated 2016 EBITDA and a range of multiples for Pride of the corresponding multiple for Ensco plus 0.0x to 2.0x, assuming an illustrative discount rate of 11% for Pride and an illustrative discount rate of 12% for Ensco. The enterprise value to forward year EBITDA multiple range used by Goldman Sachs in this analysis was derived by Goldman Sachs utilizing its experience and professional judgment, taking into account current and historical trading data and the current and historical enterprise value to forward year EBITDA multiples for Pride, Ensco and the Selected Companies referenced in “— Opinion of Goldman, Sachs & Co.—Summary of Financial Analyses of Pride’s Financial Advisor— Selected Companies Analysis” above. This analysis resulted in a range of implied exchange ratios of 0.37x to 0.64x. Based on a range of multiples for Pride of 4.0x to 12.0x estimated 2016 EBITDA and a range of multiples for Ensco of 3.0x to 11.0x estimated 2016 EBITDA, this analysis resulted in a range of implied net present values per share of Pride common stock of $15.84 to $45.48 and per Ensco ADS of $32.52 to $76.79.

The second full paragraph on page 86 of the joint proxy statement/prospectus under the caption “The Merger—Opinion of Goldman, Sachs & Co.—Summary of Financial Analyses of Pride’s Financial Advisor” is supplemented to read as set forth below. The new text is underlined and the deleted text is stricken through.

The board of directors of Pride selected Goldman Sachs as its financial advisor because it is an internationally recognized investment banking firm that has substantial experience in transactions similar to the merger. Pursuant to a letter agreement dated January 26, 2011, Pride engaged Goldman Sachs to act as its financial advisor in connection with the mergercertain potential extraordinary transactions involving Pride. Pursuant to the terms of the engagement letter, Pride has agreed to pay Goldman Sachs a transaction fee in connection with the merger currently estimated to be approximately $42 million (which is based on the closing price of Ensco ADSs and Pride net debt as of March 31, 2011), of which $5 million became payable upon execution of the engagement letter and the remainder is contingent upon consummation of the merger. The engagement letter also provides that, in the event that a transaction fee had not been paid and there was an attempt to acquire or influence control of Pride or its Board of Directors, Pride would pay, subject to certain limitations, an advisory fee of up to $12,500,000. In addition, Pride has agreed to reimburse Goldman Sachs for its expenses, including attorneys’ fees and disbursements, and to indemnify Goldman Sachs and related persons against various liabilities, including certain liabilities under the federal securities laws.
