6 DIAMOND OFFSHORE DRILLING, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. GENERAL The consolidated financial statements of Diamond Offshore Drilling, Inc. and subsidiaries (the "Company") should be read in conjunction with the Annual Report on Form 10-K for the year ended December 31, 2000 (File No. 1-13926). Interim Financial Information The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all disclosures required by generally accepted accounting principles for complete financial statements. The consolidated financial information has not been audited but, in the opinion of management, includes all adjustments (consisting only of normal recurring accruals) necessary for a fair presentation of the consolidated balance sheets, statements of income, and statements of cash flows at the dates and for the periods indicated. Results of operations for interim periods are not necessarily indicative of results of operations for the respective full years. Cash and Cash Equivalents Short-term, highly liquid investments that have an original maturity of three months or less and deposits in money market mutual funds that are readily convertible into cash are considered cash equivalents. Marketable Securities The Company's investments are classified as available for sale and stated at fair value. Accordingly, any unrealized gains and losses, net of taxes, are reported in the Consolidated Balance Sheets in "Accumulated other comprehensive income" until realized. The cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity and such adjustments are included in the Consolidated Statements of Income in "Interest income." The cost of debt securities sold is based on the specific identification method and the cost of equity securities sold is based on the average cost method. Realized gains or losses and declines in value, if any, judged to be other than temporary are reported in the Consolidated Statements of Income in "Other income (expense)." Supplementary Cash Flow Information Cash payments made for interest on long-term debt totaled $7.5 million during both the six months ended June 30, 2001 and 2000. Cash payments made, net of refunds, for income taxes during the six months ended June 30, 2001 and 2000 totaled $2.2 million and $18.1 million, respectively. Capitalized Interest Interest cost for construction and upgrade of qualifying assets is capitalized. The Company incurred interest cost, including amortization of debt issuance costs, of $6.6 million and $15.4 million during the quarter and six months ended June 30, 2001, respectively. Interest cost capitalized during the quarter and six months ended June 30, 2001 was $0.5 million and $1.0 million, respectively. The Company incurred interest cost of $4.9 million and $8.8 million during the quarter and six months ended June 30, 2000, respectively. Interest cost capitalized during the quarter and six months ended June 30, 2000 was $3.3 million and $6.0 million, respectively. 6

7 Goodwill Goodwill is amortized on a straight-line basis over 20 years. Amortization charged to operating expense during the quarter and six months ended June 30, 2001 totaled $0.8 million and $1.7 million, respectively. For the quarter and six months ended June 30, 2000, amortization expense totaled $1.1 million and $2.2 million, respectively. Debt Issuance Costs Debt issuance costs are included in the Consolidated Balance Sheets in "Other assets" and are amortized over the terms of the related debt. Treasury Stock Depending on market conditions, the Company may, from time to time, purchase shares of its common stock in the open market or otherwise. The purchase of treasury stock is accounted for using the cost method, which reports the cost of the shares acquired in "Treasury stock" as a deduction from stockholders' equity in the Consolidated Balance Sheets. During the six months ended June 30, 2001, the Company purchased 100,000 shares of its common stock at an aggregate cost of $3.3 million, or at an average cost of $33.00 per share. In July 2001, the Company purchased 23,900 shares of its common stock at an aggregate cost of $0.8 million, or at an average cost of $33.47 per share. Common Equity Put Options In February 2001, the Company received premiums of $3.1 million for the sale of put options covering 500,000 shares of common stock. The options give the holders the right to require the Company to repurchase shares of its common stock at an exercise price of $40.00 per share at any time prior to their expiration in February 2002. The Company has the option to settle in cash or shares of common stock. Premiums received for these options are recorded in "Additional paid-in capital" in the Consolidated Balance Sheets. At June 30, 2001, all of these options were outstanding. On July 24, 2001, the Company received premiums of $1.6 million for the sale of put options covering 500,000 shares of common stock. The options give the holders the right to require the Company to repurchase shares of its common stock at an exercise price of $27.96 per share at any time prior to their expiration in February 2002. The Company has the option to settle in cash or shares of common stock. On August 2, 2001, the Company received premiums of $0.8 million for the sale of put options covering 250,000 shares of common stock. The options give the holders the right to require the Company to repurchase shares of its common stock at an exercise price of $29.50 per share at any time prior to their expiration in February 2002. The Company has the option to settle in cash or shares of common stock. Extraordinary Loss On April 6, 2001, the Company redeemed all of its outstanding 3.75% convertible subordinated notes (the "3.75% Notes") at 102.08% of the principal amount thereof plus accrued interest for a total cash payment of $397.7 million. An extraordinary loss of $7.7 million was incurred as a result of the early extinguishment of debt, consisting of $8.1 million of retirement premiums and the write-off of $3.8 million of associated debt issuance costs, net of a tax benefit of $4.2 million. See "-Long-term Debt - Convertible Subordinated Notes." Comprehensive Income Comprehensive income is the change in equity of a business enterprise during a period resulting from transactions and other events and circumstances except those from investments by owners and distributions to owners. For the quarter and six months ended June 30, 2001, comprehensive income totaled $39.7 million and $81.4 million, respectively. For the quarter and six months ended June 30, 2000, comprehensive income totaled $6.2 million and $36.0 million, respectively. Comprehensive income includes net income, foreign currency translation gains and losses, and unrealized holding gains and losses on investments. 7

8 Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimated. Reclassifications Certain amounts applicable to the prior periods have been reclassified to conform to the classifications currently followed. Such reclassifications do not affect earnings. 2. EARNINGS PER SHARE A reconciliation of the numerators and the denominators of the basic and diluted per-share computations follows:

(0.05) -- (0.05) -- ----------- ----------- ----------- ----------- NET .................................................... $ 0.32 $ 0.03 $ 0.59 $ 0.24 =========== =========== =========== =========== Diluted earnings per share ("EPS") for the quarter ended June 30, 2000 excludes 9.8 million potentially dilutive shares issuable upon conversion of the 3.75% Notes because the inclusion of such shares would be antidilutive. The computation of diluted EPS for the quarter ended June 30, 2000 and the six months ended June 30, 2001 excludes approximately 1.9 million and 6.9 million, respectively, potentially dilutive shares issuable upon conversion of the Company's zero coupon convertible debentures due 2020 (the "Zero Coupon Debentures"), issued in June 2000, as there would be an antidilutive effect on EPS. 8

9 Non-qualified stock options (i) granted in April 2001 to purchase 32,600 shares of common stock at an exercise price of $38.94 per share and (ii) granted in July 2000 to purchase 2,500 shares of common stock at an exercise price of $35.72 per share were included in the computation of diluted EPS for the quarter and the six months ended June 30, 2001. However, the incremental shares calculated were immaterial for presentation purposes. Stock options were not included in the computation of diluted EPS for both periods ended June 30, 2000 because the options' price was greater than the average market price of the common stock. 3.

Convertible Subordinated Notes On April 6, 2001, the Company redeemed all of its outstanding 3.75% Notes in accordance with the indenture under which the 3.75% Notes were issued. Prior to April 6, 2001, $12.4 million principal amount of the 3.75% Notes had been converted into 307,071 shares of the Company's common stock, par value $0.01 per share, at the stated conversion price of $40.50 per share. The remaining $387.6 million principal amount of the 3.75% Notes was redeemed at 102.08% of the principal amount thereof plus accrued interest for a total cash payment of $397.7 million resulting in an after-tax charge of $7.7 million, which is reported as an extraordinary loss in the Consolidated Statements of Income. Convertible Senior Debentures On April 11, 2001, the Company issued $460.0 million principal amount of 1.5% convertible senior debentures (the "1.5% Debentures") due April 15, 2031. The 1.5% Debentures are convertible into shares of the Company's common stock at an initial conversion rate of 20.3978 shares per $1,000 principal amount of debentures, subject to adjustment in certain circumstances. Upon conversion, the Company has the right to deliver cash in lieu of shares of the Company's common stock. The transaction resulted in net proceeds of approximately $449.4 million. Interest of 1.5% per year on the outstanding principal amount is payable semiannually in arrears on April 15 and October 15 of each year, beginning October 15, 2001. The 1.5% Debentures are unsecured obligations of the Company and rank equally with all of the Company's other unsecured senior indebtedness. The Company will pay contingent interest to holders of the 1.5% Debentures during any six-month period commencing after April 15, 2008 if the average market price of a 1.5% Debenture for a measurement period preceding such six-month period equals 120% or more of the principal amount of such 1.5% Debenture and the Company pays a regular cash dividend during such six-month period. The contingent interest payable per $1,000 principal amount of 1.5% Debentures, in respect of any quarterly period, will equal 50% of regular cash dividends paid by the Company per share on its common stock during that quarterly period multiplied by the conversion rate. This contingent interest component is an embedded derivative, which had no fair value on either April 11, 2001 or June 30, 2001. Holders may require the Company to purchase all or a portion of their 1.5% Debentures on April 15, 2008 at a price equal to 100% of the principal amount of the 1.5% Debentures to be purchased plus accrued and unpaid interest. The Company may choose to pay the purchase price in cash or shares of the Company's common stock or a combination of cash and common stock. In addition, holders may require the Company to purchase for cash all or a portion of their 1.5% Debentures upon a change in control (as defined). The Company may redeem all or a portion of the 1.5% Debentures at any time on or after April 15, 2008 at a price equal to 100% of the principal amount plus accrued and unpaid interest. Credit Agreement The Company's $20.0 million short-term revolving credit agreement with a U.S. bank expired in April 2001. The credit agreement provided for borrowings at various interest rates and varying commitment fees dependent upon public credit ratings. 11

12 8. COMMITMENTS AND CONTINGENCIES Raymond Verdin v. R&B Falcon Drilling USA, Inc., et al; No. G-00-488 in the United States District Court for the Southern District of Texas, Galveston Division, filed October 10, 2000. The Company was named as a defendant in a proposed class action suit filed on behalf of offshore oil workers against all of the major offshore drilling companies. The proposed class includes persons hired in the United States by the companies to work in the Gulf of Mexico and around the world. The allegation is that the companies, through trade groups, shared wage information in order to fix and suppress the wages of the workers in violation of the Sherman Antitrust Act and various state laws. Plaintiff Thomas Bryant has replaced the named plaintiff as the proposed class representative. No class has been certified as of the date of this report. The lawsuit is seeking money damages and injunctive relief as well as attorneys' fees and costs. During the first quarter of 2001, the Company recorded a $10.0 million reserve for this pending litigation in the Company's Consolidated Statements of Income. In early July 2001, the Company filed a stipulation of settlement with the District Court in which it agreed to settle the plaintiffs' outstanding claims within the limits of the reserve. The stipulation, however, is subject to approval by the District Court. On July 30, 2001 the Chief U.S. District Judge for the Southern District of Texas issued a special order transferring this case to the U.S. District Court for the Southern District of Texas, Houston Division. The lawsuit is now styled Raymond Verdin, on behalf of himself and those similarly situated v. Pride Offshore, Inc., et al; C.A. No. G-01-168. At that time all settings and deadlines then in effect were cancelled, subject to further orders from the Honorable Sim Lake, U.S. District Court Judge, Houston Division. Various other claims have been filed against the Company in the ordinary course of business, particularly claims alleging personal injuries. Management believes that the Company has established adequate reserves for any liabilities that may reasonably be expected to result from these claims. In the opinion of management, no pending or threatened claims, actions or proceedings against the Company are expected to have a material adverse effect on the Company's consolidated financial position, results of operations, or cash flows. 9. SEGMENTS AND GEOGRAPHIC AREA ANALYSIS The Company reports its operations as one reportable segment, contract drilling of offshore oil and gas wells. Although the Company provides contract drilling services from different types of offshore drilling rigs and provides such services in many geographic locations, these operations have been aggregated into one reportable segment based on the similarity of economic characteristics among all divisions and locations, including the nature of services provided and the type of customers of such services. Similar Services Revenues from external customers for contract drilling and similar services by equipment-type are listed below (eliminations offset dayrate revenues earned when the Company's rigs are utilized in its integrated services):

14 ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS. The following discussion should be read in conjunction with the Company's Consolidated Financial Statements (including the Notes thereto) included elsewhere herein. References to the "Company" mean Diamond Offshore Drilling, Inc., a Delaware corporation, and its subsidiaries. The Company is a leader in deep water drilling with a fleet of 45 offshore drilling rigs. The fleet consists of 30 semisubmersibles, 14 jack-ups and one drillship. RESULTS OF OPERATIONS General Revenues. The Company's revenues vary based upon demand, which affects the number of days the fleet is utilized and dayrates earned. Revenues can also increase or decrease as a result of the acquisition or disposal of rigs. In order to improve utilization or realize higher dayrates, the Company may mobilize its rigs from one market to another. During periods of mobilization, however, revenues may be adversely affected. As a response to changes in demand, the Company may withdraw a rig from the market by stacking it or may reactivate a rig stacked previously, which may decrease or increase revenues, respectively. Revenues from dayrate drilling contracts are recognized currently. The Company may receive lump-sum payments in connection with specific contracts. Such payments are recognized as revenues over the term of the related drilling contract. Mobilization revenues, less costs incurred to mobilize an offshore rig from one market to another, are recognized over the term of the related drilling contract. Revenues from offshore turnkey contracts are accrued to the extent of costs until the specified turnkey depth and other contract requirements are met. Income is recognized on the completed contract method. Provisions for future losses on turnkey contracts are recognized when it becomes apparent that expenses to be incurred on a specific contract will exceed the revenue from that contract. Operating Income. Operating income is primarily affected by revenue factors, but is also a function of varying levels of operating expenses. Operating expenses generally are not affected by changes in dayrates and may not be significantly affected by fluctuations in utilization. For instance, if a rig is to be idle for a short period of time, the Company may realize few decreases in operating expenses since the rig is typically maintained in a prepared state with a full crew. In addition, when a rig is idle, the Company is responsible for certain operating expenses such as rig fuel and supply boat costs, which are typically charged to the operator under drilling contracts. However, if the rig is to be idle for an extended period of time, the Company may reduce the size of a rig's crew and take steps to "cold stack" the rig, which lowers expenses and partially offsets the impact on operating income. The Company recognizes as operating expenses activities such as inspections, painting projects and routine overhauls, which meet certain criteria, that maintain rather than upgrade its rigs. These expenses vary from period to period. Costs of rig enhancements are capitalized and depreciated over the expected useful lives of the enhancements. Increased depreciation expense decreases operating income in periods subsequent to capital upgrades. 14

High Specification Floaters. Revenues. Revenues from high specification floaters during the three months ended June 30, 2001 increased by $34.5 million from the same period in 2000. Approximately $15.1 million of the revenue improvement was generated by the Ocean Confidence, which began a five-year drilling program in the Gulf of Mexico on January 5, 2001 after completion of its conversion to a high specification semisubmersible drilling unit. In addition, revenues increased approximately $10.0 million due to improvements in utilization, primarily for the Ocean Quest which worked throughout the second quarter in 2001 compared to the same period in 2000 when the rig was stacked. Utilization for high specification floaters, excluding the Ocean Confidence, was 97% during the second quarter of 2001 as compared to 74% during the second quarter of 2000. Revenues also increased approximately $7.4 million during the second quarter of 2001 due to higher average operating dayrates compared to the same quarter of 2000. The average dayrate for high specification floaters during the second quarter of 2001, excluding the Ocean Confidence, was approximately $107,900 per day compared to approximately $102,000 per day during the second quarter of 2000. Contract Drilling Expense. Contract drilling expense for high specification floaters during the three months ended June 30, 2001 increased by approximately $6.3 million from the same period in 2000. This increase resulted primarily from costs incurred by the Ocean Confidence, which began operations in January 2001. Other Semisubmersibles. Revenues. Revenues from other semisubmersibles during the three months ended June 30, 2001 increased $30.2 million from the same period in 2000. Approximately $18.3 million of the revenue increase resulted from improvements in utilization as compared to the second quarter of 2000. Utilization for the Company's other semisubmersibles during the second quarter of 2001 was 75% compared to 53% during the second quarter of 2000. In addition, revenues increased approximately $12.9 million from higher average operating dayrates during the second quarter of 2001 compared to the second quarter of 2000. The average operating dayrates for other 15

16 semisubmersibles during the second quarter of 2001 was approximately $65,000 per day compared to approximately $61,200 per day for the same period of 2000. Contract Drilling Expense. Contract drilling expense for other semisubmersibles during the three months ended June 30, 2001 increased $4.6 million from the same period in 2000. This increase resulted primarily from higher operating costs for rigs that were idle for all or part of the second quarter of 2000 but worked throughout the second quarter of 2001. Jack-Ups. Revenues. Revenues from jack-ups during the quarter ended June 30, 2001 increased $20.5 million from the same period in 2000. Approximately $23.2 million of the increase in revenues resulted from higher operating dayrates during the second quarter of 2001 compared to the second quarter of 2000. The average operating dayrate for jack-ups during the second quarter of 2001 was approximately $43,700 per day compared to approximately $22,800 per day during the second quarter of 2000. This increase was partially offset by a decline in utilization for the second quarter of 2001 compared to the second quarter of 2000. Utilization for the second quarter of 2001 was 85% compared to 93% for the same period of 2000. Lower utilization was primarily due to the Ocean Sovereign, which was stacked while undergoing shipyard repairs during the second quarter of 2001. Contract Drilling Expense. Contract drilling expense for jack-ups during the three months ended June 30, 2001 increased $1.7 million over the same period in 2000 primarily due to repairs to the Ocean Crusader and Ocean Summit during the second quarter of 2001. Integrated Services. Revenues and contract drilling expense for integrated services decreased in the second quarter of 2001 compared to the second quarter of 2000 as a result of the difference in type and magnitude of projects during the periods. During the second quarter of 2001, integrated services contributed operating income of $0.2 million to the Company's consolidated results of operations primarily due to the completion of one international turnkey project, which started in the last quarter of 2000. During the same period in 2000 operating income of $0.5 million resulted primarily from the completion of a turnkey project and engineering services provided in the Gulf of Mexico and integrated services provided in Aberdeen, Scotland. Depreciation and Amortization Expense. Depreciation and amortization expense of $42.2 million for the three months ended June 30, 2001 increased $5.6 million from $36.6 million for the same period in 2000. Higher depreciation in 2001 resulted primarily from depreciation for the Ocean Confidence, which completed its conversion from an accommodation vessel to a high specification semisubmersible drilling unit and commenced operations in January 2001. Interest Income. Interest income of $11.6 million for the three months ended June 30, 2001 increased $1.7 million from $9.9 million for the same period in 2000. This increase resulted primarily from the investment of higher cash balances generated by the sale of the Company's 1.5% convertible senior debentures due 2031 (the "1.5% Debentures") on April 11, 2001, the sale of the Company's zero coupon convertible debentures due 2020 (the "Zero Coupon Debentures") on June 6, 2000 and the December 2000 lease-leaseback of the Ocean Alliance. Cash balances available for investment were partially reduced as a result of the Company's redemption of its outstanding 3.75% convertible subordinated notes due 2007 (the "3.75% Notes") on April 6, 2001. See " --Liquidity." Interest Expense. Interest expense of $6.1 million for the quarter ended June 30, 2001 increased $4.5 million from $1.6 million for the same period in 2000 primarily as a result of less interest being capitalized due to the completion of the Ocean Confidence conversion, the issuance of the Zero Coupon Debentures on June 6, 2000, the issuance of the 1.5% Debentures on April 11, 2001 and interest expense related to the December 2000 lease-leaseback of the Ocean Alliance. This increase was partially offset by a reduction in interest expense resulting from the Company's redemption of all of its outstanding 3.75% Notes on April 6, 2001. See "--Liquidity." 16

17 Other Income and Expense (Other, net). Other income of $6.9 million for the quarter ended June 30, 2001 increased $7.5 million from other expense of $0.6 million for the same period in 2000. This increase resulted primarily from a $6.8 million gain realized on the sale of marketable securities. Income Tax Expense. Income tax expense of $25.5 million for the quarter ended June 30, 2001 increased $23.5 million from $2.0 million for the same period in 2000 primarily as a result of higher "Income before income taxes and extraordinary loss" of $71.3 million in 2001, which was partially offset by a lower effective income tax rate in 2001. The lower effective income tax rate in 2001 was primarily due to the Company's decision to permanently reinvest the earnings of its UK subsidiaries. Extraordinary Loss. On April 6, 2001, the Company redeemed all of its outstanding 3.75% Notes at 102.08% of the principal amount thereof plus accrued interest for a total cash payment of $397.7 million. An extraordinary loss of $7.7 million was incurred as a result of the early extinguishment of debt, consisting of $8.1 million of retirement premiums and the write-off of $3.8 million associated debt issuance costs, net of a tax benefit of $4.2 million. See Note 7 to the Company's Consolidated Financial Statements in Item 1 of this report. 17

High Specification Floaters. Revenues. Revenues from high specification floaters during the six months ended June 30, 2001 increased $54.4 million from the same period in 2000. Approximately $29.2 million of the revenue increase was generated by the Ocean Confidence, which began a five-year drilling program in the Gulf of Mexico on January 5, 2001 after completion of a conversion to a high specification semisubmersible drilling unit. In addition, revenues improved approximately $11.5 million during the six months ended June 30, 2001 due to an increase in the average operating dayrates compared to the same period of 2000. The average operating dayrate for high specification floaters during the six months ended June 30, 2001, excluding the Ocean Confidence, was approximately $104,700 per day as compared to approximately $96,400 per day during the six months ended June 30, 2000. Revenues also increased approximately $10.5 million during the period ended June 30, 2001 due to improvements in utilization compared to the same period in 2000. Utilization for the Company's high specification floaters, excluding the Ocean Confidence, during the first six months of 2001 was 96% as compared to 85% during the first six months of 2000. Contract Drilling Expense. Contract drilling expense for high specification floaters during the six months ended June 30, 2001 increased by $11.0 million from the same period in 2000. This increase resulted primarily from costs incurred by the Ocean Confidence, which began operations in January 2001. Other Semisubmersibles. Revenues. Revenues from other semisubmersibles during the six months ended June 30, 2001 increased $22.7 million from the same period in 2000. Approximately $13.7 million of the revenue increase resulted from improvements in utilization as compared to the six months ended June 30, 2000. Utilization for the Company's other semisubmersibles during the six months ended June 30, 2001 was approximately 69% compared to approximately 58% during the same period of 2000. The Ocean Voyager was stacked during most of the first six months of 2000, but worked throughout the corresponding period of 2001. In addition, revenues increased approximately $9.8 18

19 million as a result of higher average operating dayrates during the six months ended June 30, 2001 compared to the same period in 2000 primarily due to increased dayrates for the Ocean General and the Ocean Nomad. Contract Drilling Expense. Contract drilling expense for other semisubmersibles during the six months ended June 30, 2001 increased $0.3 million from the same period in 2000. Jack-Ups. Revenues. Revenues from jack-ups during the six months ended June 30, 2001 increased $42.9 million from the same period in 2000. Approximately $42.3 million of the increase in revenues resulted from higher operating dayrates during the first half of 2001 compared to the first half of 2000. The average operating dayrate for jack-ups during the first six months of 2001 was approximately $41,700 per day compared to approximately $21,400 per day during the same period of 2000. Improved utilization for the six months ended June 30, 2001 contributed slightly to the higher revenue for the period. Utilization improvements resulted from the Ocean Tower and the Ocean Champion, which worked in 2001 but were stacked during most of the first half of 2000. Inspection and repairs to the Ocean Nugget and repairs to the Ocean Sovereign, which kept these rigs in the shipyard during part of the six months ended June 30, 2001, partially offset these increases. Contract Drilling Expense. Contract drilling expense for jack-ups during the six months ended June 30, 2001 increased $7.2 million over the same period in 2000. This increase was due in part to operating costs for the Ocean Tower and the Ocean Champion, which worked in 2001 but were stacked during most of the first half of 2000. In addition, costs were higher in 2001 due to the inspection and repair of the Ocean Nugget and repairs to the Ocean Crusader and the Ocean Summit. Integrated Services. Revenues and contract drilling expense for integrated services increased as a result of the difference in number, type and magnitude of projects in the first half of 2001 compared to the first half of 2000. During the first half of 2001, integrated services contributed operating income of approximately $0.5 million to the Company's consolidated results of operations primarily due to the completion of one international turnkey project. During the same period in 2000, integrated services provided turnkey and integrated services at a break-even level. Depreciation and Amortization Expense. Depreciation and amortization expense for the six months ended June 30, 2001 of $83.7 million increased $10.2 million from $73.5 million for the six months ended June 30, 2000. Higher depreciation in 2001 resulted primarily from depreciation for the Ocean Confidence, which completed its conversion from an accommodation vessel to a high specification semisubmersible drilling unit and commenced operations in January 2001. General and Administrative Expense. General and administrative expense of $13.0 million for the first half of 2001 increased $1.0 million from the same period in 2000 primarily due to the final payment of Phase III costs for the Company's participation in the Subsea Mudlift Drilling Joint Industry Project. Gain on Sale of Assets. Gain on sale of assets for the six months ended June 30, 2001 of $0.2 million decreased $13.9 million from $14.1 million for the six months ended June 30, 2000. The six months ended June 30, 2000 included the January 2000 sale of the Company's jack-up drilling rig, Ocean Scotian, for $32.0 million in cash which resulted in a gain of $13.9 million ($9.0 million after tax). The rig had been cold stacked offshore The Netherlands prior to the sale. 19

20 Interest Income. Interest income of $23.3 million for the six months ended June 30, 2001 increased $4.8 million from $18.5 million for the same period in 2000. This increase resulted primarily from the investment of higher cash balances generated by the sale of the 1.5% Debentures on April 11, 2001, the sale of the Company's Zero Coupon Debentures on June 6, 2000 and the December 2000 lease-leaseback of the Ocean Alliance. Cash balances available for investment were partially reduced as a result of the Company's redemption of all of its outstanding 3.75% Notes on April 6, 2001. See " --Liquidity." Interest Expense. Interest expense of $14.4 million for the six months ended June 30, 2001 increased $11.6 million from $2.8 million for the same period in 2000. This increase was primarily a result of the issuance of the Zero Coupon Debentures on June 6, 2000, less interest being capitalized due to the completion of the Ocean Confidence conversion, interest expense related to the December 2000 lease-leaseback of the Ocean Alliance and the issuance of the 1.5% Debentures on April 11, 2001. This increase was partially offset by a reduction in interest expense resulting from the Company's redemption of all of its outstanding 3.75% Notes. See "--Liquidity." Other Income and Expense (Other, net). Other income of $10.0 million for the six months ended June 30, 2001 increased $10.7 million from other expense of $0.7 million for the same period in 2000. This increase resulted primarily from the $12.9 million gain realized on the sale of marketable securities and a $7.3 million receipt of a settlement payment for resolved litigation and was partially offset by a new $10.0 million reserve for pending litigation. Income Tax Expense. Income tax expense of $43.4 million for the six months ended June 30, 2001 increased $25.4 million from $18.0 million for the same period in 2000 primarily as a result of higher "Income before income taxes and extraordinary loss" of $80.6 million in 2001, which was partially offset by a lower effective income tax rate in 2001. The lower effective income tax rate in 2001 was primarily due to the Company's decision to permanently reinvest the earnings of its UK subsidiaries. Extraordinary Loss. On April 6, 2001, the Company redeemed all of its outstanding 3.75% Notes at 102.08% of the principal amount thereof plus accrued interest for a total cash payment of $397.7 million. An extraordinary loss of $7.7 million was incurred as a result of the early extinguishment of debt, consisting of $8.1 million of retirement premiums and the write-off of $3.8 million associated debt issuance costs, net of a tax benefit of $4.2 million. See Note 7 to the Company's Consolidated Financial Statements in Item 1 of this report. OUTLOOK Historically, there has been a strong correlation between the price of oil and natural gas and the demand for the Company's offshore drilling services. During the first half of 2001, the Company has enjoyed strong utilization and improving dayrates due, in large part, to product prices that have been significantly above historical averages, particularly for natural gas. Beginning in the third quarter of 2001, oil prices remained relatively strong but natural gas prices, although still at a level above historical averages, have declined. The Company believes the demand for its services, particularly with respect to its Gulf of Mexico jack-up fleet, could weaken if natural gas prices continue to fall. Should oil prices also begin to deteriorate, the Company believes it could experience a reduction in demand for its high specification floater and/or intermediate semisubmersible fleet. The offshore drilling industry has historically been highly competitive and cyclical, and the Company cannot predict the extent to which current conditions and trends may continue. LIQUIDITY Operating Activities. At June 30, 2001, the Company's cash and marketable securities totaled $945.7 million, up from $862.1 million at December 31, 2000. Cash provided by operating activities for the six months ended June 30, 2001 increased by $47.5 million to $138.8 million, compared to $91.3 million for the same period of the prior year. This increase in cash was primarily attributable to improved results of operations in 2001. Net income, after adjustment for non-cash 20

21 items, resulted in an increase in cash of $86.9 million. Cash usage due to changes in net working capital components was $39.4 million higher for the six months ended June 30, 2001. Investing Activities. Investing activities used $149.8 million of cash during the six months ended June 30, 2001, compared to cash usage of $214.2 million during the same period in 2000. The $64.4 million decrease in cash usage was primarily due to a reduction in capital expenditures in 2001 of $79.3 million as a result of the completion of the conversion of the Ocean Confidence. Cash usage for the Company's investments in marketable securities was $16.3 million lower in 2001 than the same period in 2000. Proceeds from the sale of assets were lower by $31.2 million primarily due to the sale of the Ocean Scotian in January 2000. Financing Activities. Cash provided by financing activities for the six months ended June 30, 2001 decreased $327.3 million to $23.5 million compared to $350.8 million for the same period in 2000. Sources of financing for the six months ended June 30, 2000 consisted primarily of the Company's issuance of the Zero Coupon Debentures in June 2000, which resulted in net proceeds of approximately $393.1 million. On April 6, 2001, the Company redeemed all of its outstanding 3.75% Notes in accordance with the indenture under which the 3.75% Notes were issued. Prior to April 6, 2001, $12.4 million principal amount of the 3.75% Notes had been converted into 307,071 shares of the Company's common stock, par value $0.01 per share, at the stated conversion price of $40.50 per share. The remaining $387.6 million principal amount of the 3.75% Notes was redeemed at 102.08% of the principal amount thereof plus accrued interest for a total cash payment of $397.7 million, resulting in an after-tax charge of $7.7 million, which is reported as an extraordinary loss in the Consolidated Statements of Income. On April 11, 2001, the Company issued $460.0 million principal amount of the 1.5% Debentures which are due April 15, 2031. The 1.5% Debentures are convertible into shares of the Company's common stock at an initial conversion rate of 20.3978 shares per $1,000 principal amount of the 1.5% Debentures, subject to adjustment in certain circumstances. Upon conversion, the Company has the right to deliver cash in lieu of shares of the Company's common stock. The transaction resulted in net proceeds of approximately $449.4 million. Interest of 1.5% per year on the outstanding principal amount is payable semiannually in arrears on April 15 and October 15 of each year, beginning October 15, 2001. The 1.5% Debentures are unsecured obligations of the Company and rank equally with all of the Company's other unsecured senior indebtedness. The Company will pay contingent interest to holders of the 1.5% Debentures during any six-month period commencing after April 15, 2008 if the average market price of a 1.5% Debenture for a measurement period preceding such six-month period equals 120% or more of the principal amount of such 1.5% Debenture and the Company pays a regular cash dividend during such six-month period. The contingent interest payable per $1,000 principal amount of 1.5% Debentures, in respect of any quarterly period, will equal 50% of regular cash dividends paid by the Company per share on its common stock during that quarterly period multiplied by the conversion rate. This contingent interest component is an embedded derivative, which had no fair value on either April 11, 2001 or June 30, 2001. Holders may require the Company to purchase all or a portion of their 1.5% Debentures on April 15, 2008 at a price equal to 100% of the principal amount of the 1.5% Debentures to be purchased plus accrued and unpaid interest. The Company may choose to pay the purchase price in cash or shares of the Company's common stock or a combination of cash and common stock. In addition, holders may require the Company to purchase for cash all or a portion of their 1.5% Debentures upon a change in control (as defined). The Company may redeem all or a portion of the 1.5% Debentures at any time on or after April 15, 2008 at a price equal to 100% of the principal amount plus accrued and unpaid interest. Additional cash used in financing activities during the six months ended June 30, 2001 included $33.3 million for dividends paid to stockholders which were partially offset by premiums of $3.1 million received for the February 2001 sale of put options covering 500,000 shares of the Company's common stock. The options give the holders the right to require the Company to repurchase shares of its common stock at an exercise price of $40.00 per share at any 21

22 time prior to their expiration in February 2002. The Company has the option to settle in cash or shares of its common stock. All of these options were outstanding at June 30, 2001. On July 24, 2001, the Company received premiums of $1.6 million for the sale of put options covering 500,000 shares of common stock. The options give the holders the right to require the Company to repurchase shares of its common stock at an exercise price of $27.96 per share at any time prior to their expiration in February 2002. The Company has the option to settle in cash or shares of common stock. On August 2, 2001, the Company received premiums of $0.8 million for the sale of put options covering 250,000 shares of common stock. The options give the holders the right to require the Company to repurchase shares of its common stock at an exercise price of $29.50 per share at any time prior to their expiration in February 2002. The Company has the option to settle in cash or shares of common stock. In June 2001, the Company purchased 100,000 shares of its common stock at an aggregate cost of $3.3 million, or at an average cost of $33.00 per share. The cash from this transaction was recorded in the Company's Consolidated Balance Sheets in July 2001. The Company also purchased 23,900 shares of its common stock in July 2001 at an aggregate cost of $0.8 million, or at an average cost of $33.47 per share. Depending on market conditions, the Company may, from time to time, purchase shares of its common stock in the open market or otherwise. Other. The Company has the ability to issue an aggregate of approximately $117.5 million in debt, equity and other securities under a shelf registration statement. In addition, the Company may issue, from time to time, up to eight million shares of common stock, which shares are registered under an acquisition shelf registration statement (upon effectiveness of an amendment thereto reflecting the effect of the two-for-one stock split declared in July 1997), in connection with one or more acquisitions by the Company of securities or assets of other businesses. The Company believes it has the financial resources needed to meet its business requirements in the foreseeable future, including capital expenditures for rig upgrades and continuing rig enhancements, and working capital requirements. CAPITAL RESOURCES Cash required to meet the Company's capital commitments is determined by evaluating rig upgrades to meet specific customer requirements and by evaluating the Company's continuing rig enhancement program, including water depth and drilling capability upgrades. It is management's opinion that operating cash flows and the Company's cash reserves will be sufficient to meet these capital commitments; however, periodic assessments will be made based on industry conditions. In addition, the Company may, from time to time, issue debt or equity securities, or a combination thereof, to finance capital expenditures, the acquisition of assets and businesses, or for general corporate purposes. The Company's ability to effect any such issuance will be dependent on the Company's results of operations, its current financial condition, current market conditions, and other factors, many of which are beyond its control. The Company expects to spend $200.0 million for rig upgrade capital expenditures during 2001 with $125.0 million projected for the deepwater upgrade of the Ocean Baroness. During the six months ended June 30, 2001, the Company expended approximately $48.3 million, including capitalized interest expense, primarily for the Ocean Baroness and Ocean Nomad rig upgrades. Accommodation and stability enhancement upgrades were completed on the Ocean Nomad in April 2001. The significant upgrade of the Company's semisubmersible rig, the Ocean Baroness, to high specification capabilities is expected to result in an enhanced version of the Company's previous Victory-class upgrades. The upgrade includes the following enhancements: capability for operation in 6,500 feet water depths; approximately 5,590 metric tons variable deckload; a 15,000 psi blow-out prevention system; and riser with a multiplex control system. Additional features including a high capacity deck crane, significantly enlarged cellar deck area and a 25 feet by 90 feet moon pool will provide enhanced subsea completion and development capabilities. Water depths in excess of 6,500 feet should be achievable utilizing preset taut-leg mooring systems on a case by case basis. The rig is scheduled for delivery at the end of the first quarter of 2002 at a cost expected to be approximately $180.0 million. The Company expended approximately $30.8 million for the deepwater upgrade of the Ocean Baroness during the 22

23 first half of 2001. The Company has received a letter of intent from Murphy Sabah Oil Co., Ltd., a subsidiary of Murphy Oil Corporation, to contract the Ocean Baroness to drill two deep water wells, with options for additional wells, offshore Southeast Asia. The Company has announced plans to upgrade another one of its Victory-class semisubmersibles, the Ocean Rover, to a water depth of 6,500 feet, with specifications similar to the enhanced Ocean Baroness. It is estimated that this upgrade will cost approximately $200.0 million with $25.0 million estimated to be spent in 2001. The upgrade is expected to take approximately 19 months to complete. The Company also announced plans to spend approximately $100.0 million over the next 12-24 months to upgrade six of its jack-up rigs. The Company expects to spend approximately $30.0 million on these upgrades in 2001. The Ocean Titan and the Ocean Tower, both 350 feet water depth capability independent-leg slot rigs, will be converted to 350 feet independent-leg cantilever rigs. The Ocean Spartan, the Ocean Spur, the Ocean Sovereign and the Ocean Heritage, all 250 feet water depth capability independent-leg cantilever rigs, will be upgraded to 300 feet independent-leg cantilever rigs. The equipment necessary for these upgrades will be pre-fabricated and installation is planned to occur as idle time or scheduled surveys arise to minimize downtime. The Company expects to finance these upgrades through the use of existing cash balances or internally generated funds. During the six months ended June 30, 2001, the Company expended approximately $48.0 million in association with its continuing rig enhancement program and to meet other corporate requirements. These expenditures included the upgrade of pre-load tanks and jacking systems, purchases of king-post cranes, drill pipe, anchor chain, riser, and other drilling equipment. The Company has budgeted $106.0 million for 2001 capital expenditures associated with its continuing rig enhancement program and other corporate requirements. The Company continues to consider transactions which include, but are not limited to, the purchase of existing rigs, construction of new rigs and the acquisition of other companies engaged in contract drilling or related businesses. Certain of these potential transactions reviewed by the Company would, if completed, result in its entering new lines of business. In general, however, these opportunities have been related in some manner to the Company's existing operations. Although the Company does not, as of the date hereof, have any commitment with respect to a material acquisition, it could enter into such an agreement in the future and such acquisition could result in a material expansion of its existing operations or result in the Company entering a new line of business. Some of the potential acquisitions considered by the Company could, if completed, result in the expenditure of a material amount of funds or the issuance of a material amount of debt or equity securities. INTEGRATED SERVICES The Company's wholly owned subsidiary, Diamond Offshore Team Solutions, Inc. ("DOTS"), from time to time, selectively engages in drilling services pursuant to turnkey or modified-turnkey contracts under which DOTS agrees to drill a well to a specified depth for a fixed price. In such cases, DOTS generally is not entitled to payment unless the well is drilled to the specified depth and other contract requirements are met. Profitability of the contract is dependent upon its ability to keep expenses within the estimates used in determining the contract price. Drilling a well under a turnkey contract therefore typically requires a greater cash commitment by the Company and exposes the Company to risks of potential financial losses that generally are substantially greater than those that would ordinarily exist when drilling under a conventional dayrate contract. DOTS also offers a portfolio of drilling services including overall project management, extended well tests, and completion operations. During the six months ended June 30, 2001, DOTS contributed operating income of $0.5 million to the Company's consolidated results of operations, primarily from the completion of one international turnkey project. During the same period in 2000, DOTS provided turnkey and integrated services at the break-even level. ACCOUNTING STANDARDS In July 2001, the Financial Accounting Standards Board ("FASB") issued two new pronouncements: Statement of Financial Accounting Standards ("SFAS") No. 141, "Business Combinations", and SFAS No. 142, "Goodwill and Other Intangible Assets". SFAS No. 141 prohibits the use of the pooling-of-interest method for business combinations initiated after June 30, 2001 and also applies to all business combinations accounted for by the purchase method that are completed after June 30, 2001. There are also transition provisions that apply to business combinations completed before July 1, 2001, that were accounted for by the purchase method. SFAS No. 142 is effective for fiscal years beginning after December 15, 2001 for all goodwill and other intangible assets recognized in an entity's statement of 23

24 financial position at that date, regardless of when those assets were initially recognized. The Company is currently evaluating the provisions of SFAS No. 141 and SFAS No. 142 and has not adopted such provisions in its June 30, 2001 financial statements. In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." In June 2000, the FASB issued SFAS No. 138, which amended certain provisions of SFAS No. 133 to clarify four areas causing difficulties in implementation. The amendment included expanding the normal purchase and sale exemption for supply contracts, permitting the offsetting of certain intercompany foreign currency derivatives and thus reducing the number of third party derivatives, permitting hedge accounting for foreign currency denominated assets and liabilities, and redefining interest rate risk to reduce sources of ineffectiveness. The Company adopted SFAS No. 133 and the corresponding amendments under SFAS No. 138 on January 1, 2001. Adoption of SFAS No. 133, as amended by SFAS No. 138, has not had nor is it expected to have a material impact on the Company's consolidated results of operations, financial position or cash flows. FORWARD-LOOKING STATEMENTS Certain written and oral statements made or incorporated by reference from time to time by the Company or its representatives are "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements include, without limitation, any statement that may project, indicate or imply future results, events, performance or achievements, and may contain the words "expect," "intend," "plan," "anticipate," "estimate," "believe," "will be," "will continue," "will likely result," and similar expressions. Statements by the Company in this report that contain forward-looking statements include, but are not limited to, discussions regarding future market conditions and the effect of such conditions on the Company's future results of operations (see "-- Outlook"), future uses of and requirements for financial resources, including, but not limited to, expenditures related to the deepwater upgrades of the Ocean Baroness and the Ocean Rover (see "-- Liquidity" and "-- Capital Resources"). Such statements inherently are subject to a variety of risks and uncertainties that could cause actual results to differ materially from those projected. Such risks and uncertainties include, among others, general economic and business conditions, casualty losses, industry fleet capacity, changes in foreign and domestic oil and gas exploration and production activity, competition, changes in foreign, political, social and economic conditions, regulatory initiatives and compliance with governmental regulations, customer preferences and various other matters, many of which are beyond the Company's control. The risks included here are not exhaustive. Other sections of this report and the Company's other filings with the Securities and Exchange Commission include additional factors that could adversely impact the Company's business and financial performance. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements. The Company expressly disclaims any obligation or undertaking to release publicly any updates or revisions to any forward-looking statement to reflect any change in the Company's expectations with regard thereto or any change in events, conditions or circumstances on which any forward-looking statement is based. 24

25 ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK. The information included in this Item is considered to constitute "forward-looking statements" for purposes of the statutory safe harbor provided in Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. See "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Forward-Looking Statements" in Item 2 of Part I of this report. The Company's financial instruments include the Zero Coupon Debentures, the 1.5% Debentures, the Ocean Alliance lease-leaseback agreement, and investments in debt securities, including U.S. Treasury and other U.S. government corporations and agency securities, treasury inflation-indexed protected bonds ("TIP's"), and collateralized mortgage obligations ("CMO's"). At June 30, 2001, the fair value of the Company's 1.5% Debentures, based on quoted market prices, was approximately $419.6 million, compared to a carrying amount of $460.0 million. At June 30, 2001, the contingent interest component of the Company's 1.5% Debentures was carried at its fair value of zero. At June 30, 2001, the fair value of the Company's Zero Coupon Debentures, based on quoted market prices, was approximately $388.0 million, compared to a carrying amount of $417.4 million. At June 30, 2001, the fair value of the Company's Ocean Alliance lease-leaseback agreement, based on the present value of estimated future cash flows using a discount rate of 8.11%, was approximately $54.7 million, compared to a carrying amount of $56.1 million. At June 30, 2001, the fair market value of the Company's investment in debt securities issued by the U.S. Treasury and other U.S. government corporations and agencies, excluding TIP's and CMO's, was approximately $448.1 million, which includes an unrealized holding loss of $0.7 million. These securities bear interest at rates ranging from 4.8% to 7.6%. These securities are U.S. government-backed, generally short-term and readily marketable. 25

26 The fair market value of the Company's investment in TIP's at June 30, 2001 was approximately $244.0 million, which includes an unrealized holding gain of $6.8 million. These securities bear interest at rates ranging from 3.5% to 3.6% and have an inflation-adjusted principal. The amount of each semiannual interest payment is based on the securities' inflation-adjusted principal amount on an interest payment date and, at maturity, the securities will be redeemed at the greater of their inflation-adjusted principal or par amount at original issue. The TIP's are short-term and readily marketable. The fair market value of the Company's investment in CMO's at June 30, 2001 was approximately $96.6 million, which includes an unrealized holding gain of $0.2 million. The CMO's are also short-term and readily marketable with an implied AAA rating backed by U.S. government guaranteed mortgages. Other than trade accounts receivable and trade accounts payable, the Company does not currently have financial instruments that are sensitive to foreign currency exchange rates. 26

27 PART II. OTHER INFORMATION ITEM 1. LEGAL PROCEEDINGS. Raymond Verdin v. R&B Falcon Drilling USA, Inc., et al; No. G-00-488 in the United States District Court for the Southern District of Texas, Galveston Division, filed October 10, 2000. The Company was named as a defendant in a proposed class action suit filed on behalf of offshore oil workers against all of the major offshore drilling companies. The proposed class includes persons hired in the United States by the companies to work in the Gulf of Mexico and around the world. The allegation is that the companies, through trade groups, shared wage information in order to fix and suppress the wages of the workers in violation of the Sherman Antitrust Act and various state laws. Plaintiff Thomas Bryant has replaced the named plaintiff as the proposed class representative. No class has been certified as of the date of this report. The lawsuit is seeking money damages and injunctive relief as well as attorneys' fees and costs. During the first quarter of 2001, the Company recorded a $10.0 million reserve for this pending litigation in the Company's Consolidated Statements of Income. In early July 2001, the Company filed a stipulation of settlement with the District Court in which it agreed to settle the plaintiffs' outstanding claims within the limits of the reserve. The stipulation, however, is subject to approval by the District Court. On July 30, 2001 the Chief U.S. District Judge for the Southern District of Texas issued a special order transferring this case to the U.S. District Court for the Southern District of Texas, Houston Division. The lawsuit is now styled Raymond Verdin, on behalf of himself and those similarly situated v. Pride Offshore, Inc., et al; C.A. No. G-01-168. At that time all settings and deadlines then in effect were cancelled, subject to further orders from the Honorable Sim Lake, U.S. District Court Judge, Houston Division. The Company and its subsidiaries are named defendants in various lawsuits and are involved from time to time as parties to governmental proceedings, all arising in the ordinary course of business. Although the outcome of lawsuits or other proceedings involving the Company and its subsidiaries cannot be predicted with certainty and the amount of any liability that could arise with respect to such lawsuits or other proceedings cannot be predicted accurately, management does not expect these matters to have a material adverse effect on the financial position, results of operations, or cash flows of the Company.
