SECTION 2.1. Put Option . (a) Pacific Drilling shall have the option to sell to TOIVL, and to cause TOIVL to purchase, all (but not less than all) of the Pacific Drilling Shares. Transocean shall cause TOIVL to perform all covenants, agreements, obligations and liabilities of TOIVL under this Article II. In the event that Transocean is unable to cause TOIVL to perform such covenants, agreements, obligations and liabilities, Transocean shall either cause another wholly owned subsidiary of Transocean to perform such covenants, agreements, obligations and liabilities or shall itself perform such covenants, agreements, obligations and liabilities.

(b) The Put Option may be exercised by Pacific Drilling in its sole discretion on any Put Date by delivery of written notice (a “Put Notice”) to TOIVL and Transocean on any such Put Date of Pacific Drilling’s election to exercise the Put Option. The Put Option shall be exercised and irrevocable upon receipt of the Put Notice by TOIVL and Transocean.

(c) At the Consideration Election Date, Pacific Drilling will be deemed to have made to TOIVL and Transocean the representations and warranties set forth in Schedule B, and TOIVL and Transocean will be deemed to have made to Pacific Drilling the representations and warranties set forth in Schedule C (in each case, with any schedules or incomplete or bracketed information to be appropriately completed in a certificate delivered at the Consideration Election Date). On the Consideration Election Date, Pacific Drilling will deliver written notice (the “Consideration Election Notice”) to TOIVL and Transocean specifying the form of Consideration Pacific Drilling has elected to receive pursuant to Section 2.2. Pacific Drilling will be bound by the Consideration Election Notice, which shall be irrevocable upon receipt thereof by TOIVL and Transocean.

(d) The Put Closing shall take place on the Put Closing Date at the offices of the Company or on such other date and at such other place as Pacific Drilling and TOIVL shall agree; provided that if Pacific Drilling elects to receive Cash Consideration pursuant to Section 2.2, TOIVL may elect to defer the Put Closing until the 120th day following the Put Notice Date (except to the extent TOIVL can reasonably procure any required funding prior thereto). Upon the Put Closing, Pacific Drilling will be deemed to have made to TOIVL and Transocean the representations and warranties set forth in Schedule B, and TOIVL and Transocean will be deemed to have made to Pacific Drilling the representations and warranties set forth in Schedule C (with any schedules or incomplete or bracketed information to be appropriately completed in a certificate delivered at the Put Closing). At the Put Closing, (i) TOIVL (and Transocean in the case of Stock Consideration) shall deliver the Consideration in an amount equal to the Purchase Price (as set forth in Section 2.2 and 2.3) to or upon the order of Pacific Drilling and (ii) Pacific Drilling shall deliver to or upon the order of TOIVL the Pacific Drilling Shares duly endorsed for transfer or accompanied by blank stock powers. Each of the parties hereto will use its commercially reasonable best efforts to cause the Put Closing to occur as promptly as is reasonably practical following the Put Notice Date; provided that if Pacific Drilling elects to receive Cash Consideration pursuant to Section 2.2, TOIVL may elect to defer the Put Closing until the 120th day following the Put Notice Date (except to the extent Transocean can reasonably procure any required funding prior thereto).

(e) TOIVL may designate any other Person to purchase the Shares to be sold pursuant to the exercise of the Put Option; provided that any such designation shall not relieve TOIVL of its obligations hereunder or affect the Consideration to be paid for the Shares upon exercise of the Put Option.

SECTION 2.2. Consideration. Pacific Drilling shall elect in its Consideration Election Notice to be paid upon the Put Closing, in its sole discretion, either (i) in U.S. dollars by wire transfer of immediately available funds to an account designated in writing by Pacific Drilling not less than two (2) Business Days prior to the Put Closing (the “Cash Consideration”), or (ii) subject to Section 2.8(b), in Transocean Ordinary Shares (the “Stock Consideration”). If Pacific Drilling elects Stock Consideration, the Consideration Election Notice shall also specify whether Pacific Drilling elects to receive the Gross Stock Consideration or the Net Stock Consideration. If Pacific Drilling fails to deliver such Consideration Election Notice on the Consideration Election Date, TOIVL shall within one (1) Business Day of such failure elect the form of Consideration by written notice to Pacific Drilling, which shall be deemed to constitute the Consideration Election Notice.

SECTION 2.3. Purchase Price. (a) The price (the “Purchase Price”) to be paid to Pacific Drilling by TOIVL for the sale of the Pacific Drilling Shares at the Put Closing shall be (i) if Pacific Drilling elects to receive Cash Consideration pursuant to Section 2.2 or Section 2.7(b), an amount equal to the excess of (x) the Fair Value of Pacific Drilling Shares over (y) the Pacific Drilling Percentage of the aggregate amount of Indebtedness of the Company and its Subsidiaries on a consolidated basis outstanding on the Put Closing Date (other than Indebtedness included as a current liability under clause (ii) of the definition of Put Closing Date Working Capital for purposes of the adjustment contemplated by Section 2.4); or (ii) if Pacific Drilling elects to receive Stock Consideration pursuant to Section 2.2, the number of Transocean Ordinary Shares obtained, at the election of Pacific Drilling, (A) by dividing (x) the Fair Value of Pacific Drilling Shares by (y) the Transocean Share Price (the “Gross Stock Consideration”), or (B) by dividing (x) the excess of the Fair Value of the Pacific Drilling Shares over the Pacific Drilling Percentage of the aggregate amount of Indebtedness of the Company and its Subsidiaries on a consolidated basis outstanding on the Put Closing Date (other than Indebtedness included as a current liability under clause (ii) of the definition of Put Closing Date Working Capital for purposes of the adjustment contemplated by Section 2.4) by (y) the Transocean Share Price (the “Net Stock Consideration”); provided, in the case of clause (ii), that if the number of Transocean Ordinary Shares to be paid to Pacific Drilling hereunder equals or exceeds fifteen percent (15%) of the issued and outstanding Transocean Ordinary Shares on a fully-diluted basis as of the date of delivery by Pacific Drilling of the Consideration Election Notice (the “Share Cap”), Pacific Drilling shall be paid an amount in cash in lieu of such number of Transocean Ordinary Shares in excess of the Share Cap equal to the Transocean Share Price multiplied by such number of excess shares.

(b) To the extent that the Fair Value of the Drilling Rigs does not appropriately reflect all the long-term liabilities other than Indebtedness of the Company, the Fair Value of the Drilling Rigs shall be decreased for purposes of the calculation of the Fair Value of Pacific Drilling Shares by the value of such long-term liabilities, as reflected on the financial statements of the Company for the most recently completed quarter prior to the Put Closing Date.

SECTION 2.4. Working Capital Adjustment. (a) As soon as practicable but in no event later than thirty (30) days after the Put Closing Date, TOIVL will cause to be prepared and delivered to Pacific Drilling (i) the Put Closing Balance Sheet and (ii) a written statement (the “Put Closing Statement”) setting forth in reasonable detail the Put Closing Date Working Capital. The Put Closing Balance Sheet and the Put Closing Statement will be final and binding on the Shareholders unless, within twenty (20) Business Days following the delivery of the Put Closing Statement, Pacific Drilling notifies TOIVL in writing that it does not accept as correct any one or more of the amounts set forth in the Put Closing Statement. Subject to the timely delivery of such written notice, the Shareholders shall jointly appoint an internationally recognized independent accounting firm to review the Put Closing Balance Sheet and Put Closing Statement and to determine the Put Closing Date Working Capital from the Put Closing Balance Sheet so reviewed, which determination shall be made within sixty (60) Business Days after the appointment of such independent accounting firm and which determination shall be final and binding on the Shareholders.

(b) If the Put Closing Date Working Capital shall be determined with finality pursuant to Section 2.4(a) to be a positive amount, TOIVL shall, no later than five (5) Business

Days after such determination, pay in cash to Pacific Drilling an amount equal to the product of the Put Closing Date Working Capital and the Pacific Drilling Percentage. If the Put Closing Date Working Capital shall be determined with finality pursuant to Section 2.4(a) to be a negative amount, Pacific Drilling shall, no later than five (5) Business Days after such determination, pay in cash to TOIVL an amount equal to the product of the Put Closing Date Working Capital and the Pacific Drilling Percentage.

SECTION 2.5. Payment or Assumption of Debt. (a) If Pacific Drilling elects to receive the Gross Stock Consideration pursuant to Section 2.2 or Section 2.7(b), Pacific Drilling shall, at its option, on the Put Closing Date, (i) assume the payment in full of the Pacific Drilling Percentage of all the Indebtedness of the Company and its Subsidiaries on a consolidated basis outstanding on the Put Closing Date (other than loans made by the Shareholders pursuant to Section 6.02 of the Shareholders’ Agreement (and any accrued and unpaid interest thereon) and other than Indebtedness included as a current liability under clause (ii) of the definition of Put Closing Date Working Capital for purposes of the adjustment contemplated by Section 2.4) pursuant to one or more instruments in writing in a form reasonably satisfactory to TOIVL and the lenders, holders or other obligees of such Indebtedness, or (ii) pay to TOIVL on the Put Closing Date an amount in U.S. dollars in immediately available funds equal to all the Indebtedness of the Company and its Subsidiaries on a consolidated basis outstanding on the Put Closing Date (other than loans made by the Shareholders pursuant to Section 6.02 of the Shareholders’ Agreement (and any accrued and unpaid interest thereon) and other than Indebtedness included as a current liability under clause (ii) of the definition of Put Closing Date Working Capital for purposes of the adjustment contemplated by Section 2.4).

(b) Notwithstanding anything to the contrary contained herein, for all purposes of this Article II, including without limitation for purposes of Section 2.3 and Section 2.4, all loans made by the Shareholders pursuant to Section 6.02 of the Shareholders’ Agreement (and any accrued and unpaid interest thereon) shall be treated as capital of the Company. Upon the completion of the Put Closing in accordance with the terms of this Article II, all loans made by Pacific Drilling (and any accrued and unpaid interest thereon) shall be deemed to have been cancelled and paid in full and no amounts will be owing in respect thereof.

SECTION 2.6. Transfer Taxes. All stock transfer, real estate transfer, documentary, stamp, recording and other similar Taxes (including interest, penalties and additions to any such Taxes) (“Transfer Taxes”) imposed in connection with the exercise of the Put Option and the Put Closing shall be borne equally by Transocean and Pacific Drilling. The parties shall cooperate in the timely preparation, execution and filing of any Tax returns with respect to such Transfer Taxes.

SECTION 2.7. Conditions Precedent to Put Closing; Reasonable Best Efforts. As of the Put Closing Date:

(a) (i) the consummation of the transactions contemplated by this Agreement shall not be prohibited by any applicable Governmental Requirements;

(ii) there shall be no (A) injunction or restraining order of any nature issued by any Governmental Authority which directs, or which has the effect of directing,

that the Put Closing shall not be consummated as herein provided or (B) material investigation, action or other proceeding that shall have been brought by any Governmental Authority and be pending on the Put Closing Date against Pacific Drilling, TOIVL, Transocean, the Company or any Drillship Subsidiary in connection with the consummation of the transactions contemplated by this Agreement which is reasonably likely to result in an injunction or restraining order which directs, or which has the effect of directing, that the Put Closing shall not be consummated as herein provided; and

(iii) the waiting period under the Xxxx-Xxxxx-Xxxxxx Antitrust Improvements Act of 1976, as amended, if applicable to the purchase and sale of the Pacific Drilling Shares pursuant to this Agreement, shall have expired or been terminated.

(b) Each party will use its commercially reasonable best efforts to cause the conditions set forth in Section 2.7(a) to be satisfied as promptly as is reasonably practicable after the delivery of the Consideration Election Notice. In the event Pacific Drilling has elected to receive Stock Consideration but the conditions set forth in Section 2.7(a) can only be satisfied by Pacific Drilling receiving Cash Consideration, Pacific Drilling may, in its sole discretion, by notice to TOIVL change its election and instead elect to receive Cash Consideration; provided, however, that the amount of the Cash Consideration otherwise payable hereunder will be increased by four percent (4%) in accordance with Section 2.8(c).

(c) Each party will use its commercially reasonable best efforts to cause the business of the Company and its Subsidiaries to be conducted in the ordinary course of business in a manner that is consistent with past practice from the Put Notice Date through and including the Put Closing Date so as to avoid any unanticipated or unwarranted effect on the Purchase Price.

SECTION 2.8. Adjustments. (a) In the event of (i) any sale or conveyance of all or substantially all of the property and assets of Transocean to any Person (other than a Subsidiary of Transocean (unless Transocean is thereafter liquidated or dissolved) or any amalgamation of Transocean into any Person unless for the most recently completed four fiscal quarters of such Person prior to the closing of such transaction, less than thirty percent (30%) of the consolidated revenues of such Person are derived from contract drilling and/or drilling management services (on a pro forma basis giving effect to such transaction as if such transaction had been completed four full fiscal quarters prior to such closing), in which case the provisions of paragraph (c) below shall apply) or (ii) any split-off or spin-off of any Person holding all or substantially all of the property and assets of Transocean, then the provisions of this Agreement relating to Transocean and the Transocean Ordinary Shares shall be deemed to refer to such Person and its capital stock (and prior to or at the time of entering into any transaction or series of related transactions with such Person that results in the events contemplated by clauses (i) and (ii), Transocean shall cause such Person to enter into an agreement providing that it will comply with and be bound by the terms hereof).

(b) In the event that (i) the Transocean Ordinary Shares are no longer listed and widely traded on a recognized securities exchange and (ii) the capital stock of any Person which directly or indirectly owns more than fifty percent (50%) of the outstanding Transocean Ordinary Shares is so listed and widely traded, then the provisions of this Agreement relating to

Transocean and the Transocean Ordinary Shares shall be deemed to refer to such Person and such capital stock (and prior to or at the time of entering into any transaction or series of related transactions with such Person that results in the events contemplated by clauses (i) and (ii), Transocean shall cause such Person to enter into an agreement providing that it will comply with and be bound by the terms hereof), unless for the most recently completed four fiscal quarters of such Person prior to the closing of such transaction (on a pro forma basis giving effect to such transaction as if such transaction had been completed four full fiscal quarters prior to such closing), less than thirty percent (30%) of the consolidated revenues of such Person are derived from contract drilling and/or drilling management services, in which case the provisions of paragraph (c) below shall apply.

(c) (i) If the issuance by Transocean to Pacific Drilling of Transocean Ordinary Shares pursuant to an election for Stock Consideration shall be prohibited by applicable law, regulation or securities exchange rule;

(ii) in the event that (x) any sale or conveyance of all or substantially all of the property and assets of Transocean to any Person other than a Subsidiary of Transocean or any amalgamation of Transocean into any Person other than a Subsidiary of Transocean and (y) for the most recently completed four fiscal quarters of such Person prior to the closing of such transaction (on a pro forma basis giving effect to such transaction as if such transaction had been completed four full fiscal quarters prior to the closing of any transaction or series of related transactions that results in the event contemplated by clause (x)), less than thirty percent (30%) of the consolidated revenues of such Person are derived from contract drilling and/or drilling management services; or

(iii) in the event that (x) the Transocean Ordinary Shares are no longer listed and widely traded on a recognized securities exchange, (y) the capital stock of any Person which directly or indirectly owns more than fifty percent (50%) of the outstanding Transocean Ordinary Shares is so listed and widely traded and (z) for the most recently completed four fiscal quarters of such Person prior to the closing of any transaction or series of related transactions that results in the event contemplated by clause (x) and (y) (on a pro forma basis giving effect to such transaction as if such transaction had been completed four full fiscal quarters prior to such closing), less than thirty percent (30%) of the consolidated revenues of such Person are derived from contract drilling and/or drilling management services,

then, in the case of clause (i) (provided that Transocean and TOIVL shall have complied with their obligations under Sections 5.1 and 5.3 in respect of any such law, regulation or rule), (ii) or (iii), Pacific Drilling shall only be entitled to receive Cash Consideration upon exercise of the Put Option; provided, however, that the amount of the Cash Consideration otherwise payable hereunder will be increased by (A) four percent (4%) in the case of clause (i) or (B) eight percent (8%) in the case of clause (ii) or (iii).

(d) In the event of any other material change in the equity capitalization or corporate structure of Transocean (i) which results in the Transocean Ordinary Shares no longer representing the principal equity ownership interest (based on aggregate market value) in Transocean, (ii) which is not otherwise contemplated by this Section 2.8 (regardless of whether

an adjustment is required thereunder) and (iii) which would have unintended or unanticipated effects on the provisions of this Article II relating to the Stock Consideration, the parties hereto will agree to appropriate changes in the terms of this Article II to give effect to the original intent of the parties hereto to the greatest extent possible.

ARTICLE IV
REGISTRATION RIGHTS

The provisions of this Article IV will apply only if Pacific Drilling elects to receive Stock Consideration pursuant to Section 2.2:

SECTION 4.1. Request for Registration. On any date after the Put Closing Date, if Transocean shall receive from Pacific Drilling a written request that Transocean effect any registration with respect to the Registrable Securities owned by the Holders (which request shall state the number of shares of Registrable Securities to be disposed of and the intended method of disposition thereof) that Transocean effect a registration with respect to the Registrable Securities owned by the Holders, which registration shall cover Registrable Securities having an aggregate fair market value (based on the then-current market value of such Registrable Securities) equal to $100 million or more unless Pacific Drilling shall hold less than $100 million of Registrable Securities, in which event, the remaining Registrable Securities held by Pacific Drilling, Transocean will as soon as reasonably practicable (provided that no Registration (as defined below) shall be required to be effected until the earlier of (i) the first anniversary of the Put Closing Date and (ii) the 15-month anniversary of the Put Notice Date but not later than the second anniversary of the Put Closing Date; provided further that in connection with any Registration on a Form S-1 or F-1 (or any successor form thereto), such Registration shall not be required to be effected earlier than ninety (90) days after receipt of such request), use all commercially reasonable best efforts to effect such registration (including, without limitation, the execution of an undertaking to file post-effective amendments, appropriate qualifications under applicable blue sky or other state securities laws and appropriate compliance with applicable regulations issued under the Securities Act) as may be so reasonably requested and as would permit or facilitate the sale and distribution of all or such portion of such Registrable Securities as are specified in such request; provided that Transocean shall not be obligated to effect, or take any action to effect, any such registration pursuant to this Agreement:

(a) after Transocean has effected two (2) registrations on behalf of the Holders (the “Registrations”), pursuant to this Agreement and, subject to the provisions below, such Registrations have been declared or ordered effective and the sales of such Registrable Securities shall have closed; provided that any requested registration commenced that is subsequently withdrawn at the request of Pacific Drilling (unless such withdrawal is due to adverse market conditions) shall count towards the number of Registrations; or

(b) if at any time Transocean provides written notice to Pacific Drilling that Transocean has determined, in its reasonable business judgment, that it would be materially disadvantageous to Transocean (including, but not limited to, because the sale of Registrable Securities covered by a registration statement or the disclosure of information therein or in any related prospectus or prospectus supplement would materially interfere with or otherwise adversely affect in any material respect any acquisition, financing, corporate reorganization or other material transaction or event, circumstance or development involving Transocean) (a “Disadvantageous Condition”) for sales of Registrable Securities under such registration statement to be permitted, Transocean may refrain from maintaining current the prospectus contained in such registration statement or cause such registration statement to be withdrawn or the effectiveness of such registration statement to be terminated, or, in the event no registration

statement has been filed, Transocean shall be entitled to not file such registration statement, for the later of (i) a reasonable period of time specified in the notice of the Disadvantageous Condition or (ii) until such Disadvantageous Condition no longer exists (written notice of which Transocean shall promptly deliver to Pacific Drilling).

Upon receipt by Pacific Drilling of any notice from Transocean of a Disadvantageous Condition, the Holders shall immediately discontinue use of the prospectus and any prospectus supplement under such registration statement and shall suspend sales of Registrable Securities for the period of time specified in the notice of the Disadvantageous Condition or until such Disadvantageous Condition no longer exists. Furthermore, if so directed by Transocean by such notice, the Holders will deliver to Transocean all copies then in its possession of the prospectus and prospectus supplements then covering such Registrable Securities at the time of receipt of such notice. In the event that Transocean makes an election under this Section 4.1, the Holders agree to keep confidential the fact of such election and any information provided by Transocean in connection therewith. In the event any registration statement in respect of a registration requested by Pacific Drilling pursuant to Section 4.1 is withdrawn or the effectiveness of such registration statement is terminated, or a registration statement is not filed in respect of such request, in each case pursuant to this Section 4.1(b), then Pacific Drilling shall have the right to withdraw its request for such registration at any time following receipt of any notice from Transocean of a Disadvantageous Condition, and, if the Pacific Drilling so withdraws its request, the Holders shall be deemed not to have used one of their rights to request a registration under this Agreement and shall continue to have such right.

SECTION 4.2. Other Shareholders. The registration statement filed pursuant to the request of Pacific Drilling may not include other securities of Transocean that are not Registrable Securities (i) which are held by Persons who, by virtue of agreements with Transocean or otherwise, are entitled to include their securities in any such registration (“Other Shareholders”), or (ii) which are to be sold by or on behalf of Transocean.

SECTION 4.3. Underwriting. If the Holders intend to distribute the Registrable Securities by means of an underwriting, Pacific Drilling shall so advise Transocean as a part of its request made pursuant to Section 4.1. If Other Shareholders request to include other securities of Transocean as part of the registration, and in the determination of the managing underwriters, such additional securities combined with the Registrable Securities to be registered pursuant to the request for Registration exceed the largest number of shares of Transocean securities (the “Maximum Offering Size”) which can be sold without having an adverse effect on such offering, including the price at which such securities can be sold, then Transocean shall include in such Registration, up to such Maximum Offering Size, first, all Registrable Securities requested to be registered by Pacific Drilling, and second, all securities requested to be included in such registration by any Other Shareholder (allocated, if necessary for the offering not to exceed the Maximum Offering Size, pro rata among such Other Shareholders on the basis of the relative number of Transocean securities requested to be included in such Registration). Pacific Drilling and Transocean shall (together with all Other Shareholders proposing to distribute their securities through such underwriting) enter into an underwriting agreement in customary form with the representative of the underwriter or underwriters selected for such underwriting by Pacific Drilling which shall include representations and warranties of selling shareholders.

SECTION 4.4. Form S-3 or Form F-3. Notwithstanding anything to the contrary in Section 4.1, so long as Transocean qualifies for registration on Form S-3 or F-3 (or any successor form thereto) for secondary sales, any request for registration by Pacific Drilling shall be a request for registration on Form S-3 or F-3 (or any successor form thereto), and shall be subject to the conditions and limitations set forth in Section 4.1.

SECTION 4.5. No Assignment. The registration rights set forth in this Article IV may not be assigned, in whole or in part, to any transferee of Registrable Securities, other than a Permitted Transferee.

SECTION 4.6. Expenses of Registration. All Registration Expenses and Selling Expenses incurred in connection with any registration, qualification or compliance pursuant to this Article IV shall be borne by Pacific Drilling.

SECTION 4.7. Registration Procedures. In the case of each registration effected by Transocean pursuant to Article IV, Transocean will keep Pacific Drilling advised in writing as to the initiation of each registration and as to the completion thereof. At Pacific Drilling’s expense, Transocean will:

(a) Keep such registration effective for a period of 120 days or until Pacific Drilling has completed the distribution described in the registration statement relating thereto, whichever first occurs; provided, however, that (i) such 120-day period shall be extended for a period of time equal to the period during which Pacific Drilling is prohibited from selling any securities included in such registration as a result of a Disadvantageous Condition; and (ii) in the case of any registration of Registrable Securities on Form S-3 or F-3 which are intended to be offered on a continuous or delayed basis, such 120-day period shall be extended until all such Registrable Securities are sold, provided that Rule 415, or any successor rule under the Securities Act, permits an offering on a continuous or delayed basis, and provided further that applicable rules under the Securities Act governing the obligation to file a post-effective amendment permit, in lieu of filing a post-effective amendment which includes any prospectus required by Section 10(a) of the Securities Act or reflects facts or events representing a material or fundamental change in the information set forth in the registration statement, the incorporation by reference in the registration statement of such information included in periodic reports filed pursuant to Section 12 or 15(d) of the Exchange Act;

(b) furnish such number of prospectuses and other documents incident thereto as Pacific Drilling from time to time may reasonably request;

(c) notify Pacific Drilling at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; and

(d) furnish, on the date that such Registrable Securities are delivered to the underwriters for sale, if such securities are being sold through underwriters or, if such securities

are not being sold through underwriters, on the date that the registration statement with respect to such securities becomes effective, (i) an opinion, dated as of such date, of the counsel representing Transocean for the purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering, addressed and reasonably satisfactory to the underwriters, if any, and to Pacific Drilling and (ii) a letter, dated as of such date, from the independent certified public accountants of Transocean, in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering addressed and reasonably satisfactory to the underwriters, if any, and if permitted by applicable accounting standards, to Pacific Drilling.

SECTION 4.8. Indemnification. (a) Transocean agrees to indemnify and hold harmless Pacific Drilling and each Holder, each of its officers and directors, and each person controlling Pacific Drilling or such Holder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, with respect to each registration which has been effected pursuant to this Article IV, and each underwriter, if any, and each person who controls any underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration under which the Registrable Securities were registered under the Securities Act, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereof, or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of any preliminary prospectus or final prospectus, in the light of the circumstances under which they were made) not misleading, and will reimburse Pacific Drilling and each Holder, each of its officers, directors and partners, and each person controlling Pacific Drilling or such Holder, each such underwriter and each person who controls any such underwriter, for any legal or other expenses reasonably incurred (as incurred) in connection with investigating or defending any such claim, loss, damage, liability or action; provided, however, that Transocean will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement (or alleged untrue statement) or omission (or alleged omission) based upon written information furnished to Transocean by Pacific Drilling, any Holder or any underwriter and stated to be specifically for use therein; provided further, that Transocean shall not be liable in any such case with respect to an offer or sale of Registrable Securities during any period in which Holders are required pursuant to Section 4.1(b) to discontinue use of the prospectus and any prospectus supplement under the registration statement and to suspend sales of Registrable Securities.

(b) Pacific Drilling and each Holder will indemnify Transocean, each of its directors and officers and each underwriter, if any, of Transocean’s securities covered by such a registration statement, each person who controls Transocean or such underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, each Other Shareholder and each of their officers and directors, and each person controlling such Other Shareholder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration under which the Registrable Securities were registered under the Securities Act, any preliminary prospectus or final prospectus contained therein, or any

amendment or supplement thereof made by Pacific Drilling or such Holder in writing, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements by Pacific Drilling or such Holder therein not misleading, and will reimburse Transocean and such Other Shareholders, directors, officers, underwriters or control persons for any legal or other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to Transocean by Pacific Drilling or such Holder and stated to be specifically for use therein.

Transocean may require, as a condition to entering into any underwriting agreement in connection with the Registrable Securities, that Transocean shall have received an undertaking reasonably satisfactory to it from each underwriter named in any such underwriting agreement, severally and not jointly, to (i) indemnify and hold harmless Transocean, and all other holders of Registrable Securities, against any losses, claims, damages or liabilities to which Transocean or such other holders of Registrable Securities may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the registration statement, the final prospectus, or any issuer free writing prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made (in the case of the final prospectus or any issuer free writing prospectus), not misleading, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) was made in reliance upon and in conformity with written information furnished to Transocean by the underwriter expressly for use therein, and (ii) reimburse Transocean for any legal or other expenses reasonably incurred by Transocean in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Each party entitled to indemnification under this Section 4.8 (the “Indemnified Party”) shall give notice in writing to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld) and the Indemnified Party may participate in such defense at such party’s expense (unless the Indemnified Party shall have reasonably concluded that there may be a conflict of interest between the Indemnifying Party and the Indemnified Party in such action, in which case the fees and expenses of counsel shall be at the expense of the Indemnifying Party), and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 4.8 except to the extent the Indemnifying Party is materially prejudiced thereby. No Indemnifying Party, in the defense of any such claim or litigation shall, except with the prior written consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional

term thereof the giving by the claimant or plaintiff to such Indemnified Party and its Affiliates of a release from all liability in respect to such claim or litigation. Each Indemnified Party shall furnish such information regarding itself or the claim in question as an Indemnifying Party may reasonably request in writing and as shall be reasonably required in connection with the defense of such claim and litigation resulting therefrom.

(d) If the indemnification provided for in this Section 4.8 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability, claim, damage or expense referred to herein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions which resulted in such loss, liability, claim, damage or expense, as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue (or alleged untrue) statement of a material fact or the omission (or alleged omission) to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with any underwritten public offering contemplated by this Agreement are in conflict with the foregoing provisions, the provisions in such underwriting agreement shall control.

(f) The provisions of this Section 4.8 shall remain in full force and effect, regardless of any investigation made by or on behalf of any Holder or Transocean or any of the indemnified persons referred to in this Section 4.8, and shall survive the sale by a Holder of securities covered by the registration statement.

SECTION 4.9. Information by Pacific Drilling and the Holders. Pacific Drilling and the Holders shall furnish to Transocean such information regarding Pacific Drilling and the Holders and the distribution proposed by Pacific Drilling and the Holders as Transocean may reasonably request in writing and as shall be reasonably required in connection with any registration, qualification or compliance referred to in this Article IV.

SECTION 4.10. Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission which may permit the sale of restricted securities to the public without registration, Transocean agrees to:

(a) make and keep public information available as those terms are understood and defined in Rule 144 under the Securities Act (“Rule 144”);

(b) use its commercially reasonable best efforts to file with the Commission in a timely manner all reports and other documents required of Transocean under the Securities Act and the Exchange Act; and

(c) so long as Pacific Drilling or any Holder owns any Registrable Securities, furnish to Pacific Drilling or such Holder upon request, a written statement by Transocean as to its compliance with the reporting requirements of Rule 144, and of the Securities Act and the Exchange Act, a copy of the most recent annual or quarterly report of Transocean, and such other reports and documents so filed as Pacific Drilling or such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing the Holders to sell any such securities without registration.

SECTION 4.11. Termination. The registration rights set forth in this Article IV shall not be available upon the earlier to occur of (a) the second anniversary of the Put Closing Date, unless at that time Pacific Drilling is an affiliate of Transocean for the purposes of Rule 144, or (b) if all of the Registrable Securities then owned by the Holders can be sold in any ninety (90)-day period pursuant to Rule 144. If all the Registrable Securities then owned by such Holder could be sold in any one (1)-year period pursuant to Rule 144, then the registration rights set forth in this Article IV shall not be available for an offering on a continuous or delayed basis. Notwithstanding anything to the contrary set forth in this Article IV, the provisions of this Article IV shall be of no force and effect at any time at which Transocean (or any successor or any Person which directly or indirectly controls Transocean) is not a Public Company.

SECTION 2. Authority. It has all requisite corporate power and authority to execute, deliver and perform pursuant to the terms and subject to the conditions of the Put Notice, including to sell all of the Pacific Drilling Shares on the Put Closing Date.

SECTION 3. Consents and Approvals; No Violations. The sale of all of the Pacific Drilling Shares on the Put Closing Date will not (i) conflict with or result in any breach of any provision of its organizational documents, (ii) result in a violation or breach of, or constitute (with or without due notice or lapse of time or both) a default (or give rise to any right of termination, cancellation or acceleration) under, or require any consent under, any indenture, license, contract, agreement or other instrument or obligation to which it is a party or by which it or any of its properties or assets are bound, (iii) violate any Governmental Requirements applicable to it or any of its properties or assets; or (iv) except as has been filed or obtained, require any filing with, or the obtaining of any permit, authorization, consent or approval of any Governmental Authority, except, in the case clauses of (ii), (iii) or (iv), for such violations, breaches or defaults as would not have and would not reasonably be expected to have, individually or in the aggregate, a material adverse effect on it and its Subsidiaries, taken as a whole, or on its ability to consummate the transactions contemplated hereby or perform its obligations hereunder.

SECTION 4. The Shares. It has good and valid title to its Pacific Drilling Shares to be sold to TOIVL on the Put Closing Date, free and clear of all Liens.

[The following representations and warranties will only be made if Pacific Drilling elects to receive Stock Consideration.]

SECTION 5. Securities Law Matters.

(a) It has experience in analyzing and investing in companies like Transocean and is capable of evaluating the merits and risks of an investment in Transocean and has the capacity to protect its own interests. It is an “Accredited Investor” as that term is defined in Rule 501 of Regulation D under the Securities Act. It is aware of Transocean’s business affairs and financial condition, and has acquired information about Transocean sufficient to reach an informed and knowledgeable decision to acquire the Transocean Ordinary Shares. It is acquiring the Transocean Ordinary Shares for its own account for investment purposes only not as a nominee or agent and not with a view to, or for the resale in connection with, any “distribution” thereof for purposes of the Securities Act. It has not offered or sold any portion of the Transocean Ordinary Shares to be acquired by it and has no present intention of reselling or otherwise disposing of any portion of such Transocean Ordinary Shares either currently or after the passage of a fixed or determinable period of time or upon the occurrence or nonoccurrence of any predetermined event or circumstance. It understands that investment in the Transocean Ordinary Shares is subject to a high degree of risk. It can bear the economic risk of its investment, including the full loss of its investment, and by reason of its business or financial experience or the business or financial experience of its professional advisors has the capacity to evaluate the merits and risks of its investment and protect its own interest in connection with the purchase of the Transocean Ordinary Shares. It also represents it has not been organized for the purpose of acquiring the Transocean Ordinary Shares.

(b) It understands that the Transocean Ordinary Shares have not been and, except as provided in the Put Option and Registration Rights Agreement, will not be registered under the Securities Act or any applicable state securities law in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of its investment intent and the accuracy of its representations as expressed herein and it will furnish Transocean with such additional information as is reasonably requested by Transocean in connection with such exemption.

(c) It further understands that the Transocean Ordinary Shares must be held indefinitely unless subsequently registered under the Securities Act and any applicable state securities laws, or unless exemptions from registration are otherwise available. Moreover, it understands that Transocean is under no obligation to and does not expect to register the Transocean Ordinary Shares, except as provided for in the Put Option and Registration Rights Agreement.

(d) To its knowledge, Transocean has made available copies of Transocean’s reports filed under the Exchange Act since the beginning of Transocean’s current fiscal year. It has had a reasonable opportunity to ask questions relating to and otherwise discuss Transocean’s business, management and financial affairs with Transocean’s management, and it has received satisfactory responses to its inquiries. It has relied solely on its own independent investigation before deciding to enter into the purchase of the Transocean Ordinary Shares. It is not, and has not been within the ninety (90) days prior to the Put Closing Date, a broker or dealer of securities.

(e) After giving effect to the issuance of Transocean Ordinary Shares on the Put Closing Date, Pacific Drilling is the beneficial owner of less than 15% of the issued and outstanding Transocean Ordinary Shares.
