(e) If the Time of Sale Prospectus is being used to solicit offers to buy the Units at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus in order to make the statements therein, in the light of the circumstances, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement then on file, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not, in the light of the circumstances when the Time of Sale Prospectus is delivered to a prospective purchaser, be misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with applicable law.

(g) To endeavor to qualify the Units for offer and sale under the securities or Blue Sky laws of such jurisdictions as you shall reasonably request; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify to do business or act as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

(j) To file with the Commission such information on Form 10-Q or Form 10-K as may be required by Rule 463 under the Securities Act.

10. Covenants of the Underwriters. Each Underwriter severally covenants with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of the Underwriter.

11. Indemnity and Contribution. (a) The Transocean Parties, jointly and severally, agree to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate and selling agent of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, the Time of Sale Prospectus, any Written Testing-the-Waters Communication or any road show as defined in Rule 433(h) under the Securities Act (a “road show”), or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Company in writing by such Underwriter through you expressly for use therein, which information consists solely of the information set forth in the last sentence of Section 11(b).

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Transocean Parties, the directors of the Company, the officers of the Company who sign the Registration Statement and each person, if any, who controls the Company or the Selling Unitholder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, the Time of Sale Prospectus, any Written Testing-the-Waters Communication or any road show as defined in Rule 433(h) under the Securities Act (a “road show”), or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, but only with reference to written information relating to such Underwriter furnished to the Transocean Parties by or on behalf of such Underwriter through the Representatives specifically for inclusion in any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus or road show or the Prospectus or any amendment or supplement thereto. Each Transocean Party acknowledges that the statements set forth (i) in the last paragraph of the cover page of the Prospectus regarding delivery of the Units and (ii) under the heading “Underwriting” in any Preliminary Prospectus and the Prospectus, the list of Underwriters and their respective participation in the sale of the Units, the sentences related to concessions and reallowances and the paragraphs related to stabilization, syndicate covering transactions and penalty bids constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Preliminary Prospectus, the Prospectus and any Issuer Free Writing Prospectus.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 11(a) or 11(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing, but the omission to so notify the indemnifying party shall not relieve it from any liability that it may have to any indemnified party to the extent that the indemnifying party does not suffer actual prejudice as a result of such failure, and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the indemnifying party has failed within a reasonable amount of time to retain counsel reasonably satisfactory to the indemnified party or (iii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of

more than one separate firm (in addition to any local counsel) for any such indemnified parties, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by Xxxxxx Xxxxxxx & Co. LLC. In the case of any such separate firm for the Transocean Parties, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) does not include any statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) To the extent the indemnification provided for in Section 11(a) or 11(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties, on the one hand, and the indemnified party or parties, on the other hand, from the offering of the Units or (ii) if the allocation provided by clause 11(d)(i) above is not permitted by applicable law in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 11(d)(i) above but also the relative fault of the indemnifying party or parties, on the one hand, and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Transocean Parties, on the one hand, and the Underwriters on the other hand in connection with the offering of the Units shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Units (before deducting expenses) received by the Selling Unitholder and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Units. The relative fault of the Transocean Parties, on the one hand, and the Underwriters, on the other hand, 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 any of the Transocean Parties or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 11 are several in proportion to the respective number of Units they have purchased hereunder, and not joint.

(e) The Transocean Parties and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 11 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 11(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 11(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 11, no Underwriter shall be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Units exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 11 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f) The indemnity and contribution provisions contained in this Section 11 and the representations, warranties and other statements of the Transocean Parties and the Selling Unitholder contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter, the Transocean Parties or any person controlling any Transocean Party and (iii) acceptance of and payment for any of the Units.

12. Termination of this Agreement.

(a) Termination. The Underwriters may terminate this Agreement by notice given by you to the Transocean Parties, if after the execution and delivery of this Agreement and prior to the Firm Closing Date or, with respect to any Additional Units, an Option Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, either of the New York Stock Exchange or the NASDAQ Global Market, (ii) trading of any securities of the Company should have been suspended on any exchange or on any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in your judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Units on the terms and in the manner contemplated in the Registration Statement, the Time of Sale Prospectus and the Prospectus.

(b) Survival. If this Agreement is terminated, such termination shall be without liability of any party to any other party except as provided in Section 9 hereof, and provided further that Sections 1, 2, 9, 11, and 17 shall survive such termination and remain in full force and effect.

13. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Firm Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Units that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Units which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Units to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Units set forth opposite their respective names in Schedule I bears to the aggregate number of Firm Units set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Units which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Units that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 13 by an amount in excess of one-ninth of such number of Units without the written consent of such Underwriter. If, on the Firm Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Units and the aggregate number of Firm Units with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Units to be purchased on such date, and arrangements satisfactory to you and the Transocean Parties for the purchase of such Firm Units are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Transocean Parties. In any such case either you or the Transocean Parties shall have the right to postpone the Firm Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Units and the aggregate number of Additional Units with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Units to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Units to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Units that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

14. Entire Agreement. (a) This Agreement represents the entire agreement between the Transocean Parties, on the one hand, and the Underwriters, on the other, with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Units.

(b) The Transocean Parties acknowledge that in connection with the offering of the Units: (i) the Underwriters have acted at arms-length, are not agents of, and owe no fiduciary duties to, the Transocean Parties or any other person, (ii) the Underwriters owe the Transocean Parties only those duties and obligations set forth in this Agreement and (iii) the Underwriters may have interests that differ from those of the Transocean Parties. The Transocean Parties waive to the full extent permitted by applicable law any claims they may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Units.

15. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

16. Applicable Law. This Agreement and any claim, controversy or dispute arising under or related to this Agreement shall be governed by and construed in accordance with the internal laws of the State of New York. The Transocean Parties hereby submit to the non-exclusive jurisdiction of the United States federal and state courts in the Borough of Manhattan in The City of New York (a “New York Court”) in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. The Transocean Parties irrevocably and unconditionally waive any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby in a New York Court and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum. The Transocean Parties have appointed Transocean Partners LLC as their authorized agent (the “Authorized Agent”) upon whom process may be served in any suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated herein which may be instituted in any New York Court, by any Underwriter, the directors, officers, affiliates, employees and agents of any Underwriter, or by any person who controls any Underwriter, and expressly accepts the non-exclusive jurisdiction of any such court in respect of any such suit, action or proceeding. The Transocean Parties hereby represent and warrant that the Authorized Agent has accepted such appointment and has agreed to act as said agent for service of process, and each of them agrees to take any and all action, including the filing of any and all documents that may be necessary to continue such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent shall be deemed, in every respect, effective service of process upon the Transocean Parties. To the extent that any of the Transocean Parties has or hereafter may acquire any immunity (on the grounds of sovereignty or otherwise) from the jurisdiction of any court or from any legal process with respect to itself or its property, each of the Transocean Parties irrevocably waives, to the fullest extent permitted by law, such immunity in respect of any such suit, action or proceeding.

17. Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than United States dollars, the parties hereto agree, to the fullest extent permitted by law, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Underwriters could purchase United States dollars with such other currency in The City of New York on the business day preceding that on which final judgment is given. The obligation of the Transocean Parties with respect to any sum due to any Underwriter or any person controlling any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day following receipt by such Underwriter or controlling person of any

sum in such other currency, and only to the extent that such Underwriter or controlling person may in accordance with normal banking procedures purchase United States dollars with such other currency. If the United States dollars so purchased are less than the sum originally due to such Underwriter or controlling person hereunder, the Transocean Parties agree as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter or controlling person against such loss. If the United States dollars so purchased are greater than the sum originally due to such Underwriter or controlling person hereunder, such Underwriter or controlling person agrees to pay to any such Transocean Party an amount equal to the excess of the dollars so purchased over the sum originally due to such Underwriter or controlling person hereunder.

18. Foreign Taxes. All payments made by the Transocean Parties under this Agreement, if any, will be made without withholding or deduction for or on account of any present or future taxes, duties, assessments or governmental charges of whatever nature imposed or levied by or on behalf of any non-U.S. taxing authority unless the Transocean Parties are or become required by law to withhold or deduct such taxes, duties, assessments or other governmental charges. In such event, the Transocean Parties will pay such additional amounts as will result, after such withholding or deduction, in the receipt by each Underwriter and each person controlling any Underwriter, as the case may be, of the amounts that would otherwise have been receivable in respect thereof, except to the extent such taxes, duties, assessments or other governmental charges (i) were imposed by reason of any present or former connection between an Underwriter and any such non-U.S. jurisdiction, otherwise than solely from the execution of this Agreement or the receipt of payments hereunder or thereunder; or (ii) would not have been imposed but for the failure of such Underwriter to comply with any certification, identification or other reporting requirements concerning nationality, residence, identity or connection with such non-U.S. jurisdiction of such Underwriter if such compliance is required or imposed by law as a precondition to an exemption from, or reduction in, such tax, duty or charge. The Transocean Parties further agree to indemnify and hold harmless the Underwriters against any documentary, stamp, value added, sales, financial transaction or similar issuance or recordation tax, including any interest and penalties, on the placement of the Units and on the execution and delivery of this Agreement.

19. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

20. Notices. All communications hereunder shall be in writing and effective only upon receipt and if to the Underwriters shall be delivered, mailed or sent to you c/o Morgan Xxxxxxx & Co.

7. Any Transaction Agreement to which any of the Transocean Delaware Entities is a party has been duly authorized, executed and delivered by such Transocean Delaware Entities, and assuming the due authorization, execution and delivery by the other parties thereto, each such agreement is a valid and legally binding agreement of the Transocean Delaware Entities parties thereto, enforceable against such Transocean Delaware Entities in accordance with its terms; provided that, with respect to each such agreement, the enforceability thereof may be limited by (i) bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law), and (ii) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant of good faith and fair dealing.

C-1-2

11. Assuming that the Omnibus Agreement, the Sponsor Credit Agreement, the Contribution Agreement, the Master Services Agreements, the Working Capital Note Payable, the Customer Receivables Guarantees and the Bills of Sale (the “US Covered Agreements”) have been duly authorized and validly executed and delivered by each of the Transocean Entities party thereto other than the Transocean Delaware Entities, each of the US Covered Agreements, constitutes a valid and legally binding obligation of such Transocean Entities, enforceable against each of them in accordance with its respective terms, provided that, with respect to each such agreement, the enforceability thereof may be limited by (i) bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law), and (ii) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant of good faith and fair dealing.

12. The description of the United States federal statutes and regulations set forth in the Registration Statement, the Time of Sale Prospectus and the Prospectus under the caption “Risk Factors—Risks Inherent in Our Business” and “Business—Environmental Regulation” constitute accurate summaries of such statutes and regulations in all material respects, subject to the qualifications and assumptions stated therein.

13. The statements in the Registration Statement, the Time of Sale Prospectus and the Prospectus under the captions “Our Cash Distribution Policy and Restrictions on Distributions,” “Provisions of Our Limited Liability Company Agreement Relating to Cash Distributions,” “Certain Relationships and Related Party Transactions—Agreements Governing the Transactions—Omnibus Agreement,” “Certain Relationships and Related Party Transactions—Agreements Governing the Transactions—Master Services Agreements,” “Conflicts of Interest and Duties,” “Description of the Common Units” and “The Limited Liability Company Agreement,” insofar as they constitute descriptions of any contracts and other documents, accurately describe in all material respects the portions of the contracts and other documents addressed thereby.

14. The opinion of Xxxxx Xxxxx L.L.P. that is filed as Exhibit 8.1 to the Registration Statement is confirmed, and the Underwriters may rely upon such opinion as if it were addressed to them.

In rendering such opinion, such counsel may (i) rely in respect of matters of fact upon representations and warranties of the Transocean Parties, upon certificates of officers and employees of the Transocean Entities and upon information obtained from public officials, (ii) assume that all documents submitted to them as originals are authentic, that all copies submitted to them conform to the originals thereof, and that the signatures on all documents examined by them are genuine, (iii) state that its opinion is limited to matters governed by federal law and the applicable laws of the States of Delaware, New York and Texas (iv) state that they express no opinion with respect to (a) any permits to own or operate any real or personal property or (b) any state or local, estate, gift or alternative minimum tax considerations concerning the ownership or disposition of the Units.

In addition, such counsel shall state that they have reviewed the Registration Statement, the Time of Sale Prospectus and the Prospectus and have participated in conferences with officers and other representatives of the Transocean Entities, with representatives of the Company’s independent registered public accounting firm, and with your representatives and your counsel, at which the contents of the Registration Statement, the Time of Sale Prospectus, the Prospectus and related matters were discussed. The purpose of such counsel’s professional engagement was not to establish or confirm factual matters set forth in the Registration Statement, the Time of Sale Prospectus or the Prospectus, and such counsel has not undertaken to verify independently any of the factual matters in such documents. Moreover, many of the determinations required to be made in the preparation of the Registration Statement, the Time of Sale Prospectus and the Prospectus involve matters of a non-legal nature. Accordingly, such counsel is not passing upon, and does not assume any responsibility for, the accuracy, completeness or fairness of the statements contained or included in the Registration Statement, the Time of Sale Prospectus and the Prospectus (except to the extent stated in paragraphs 12 and 13 above). Subject to the foregoing and on the basis of the information such counsel gained in the course of performing the services referred to above, such counsel advises you that:

(a) the Registration Statement, when it became effective, the Time of Sale Prospectus, as of the Applicable Time, and the Prospectus, as of its date and the applicable Closing Date, appear on their face to be appropriately responsive in all material respects to the requirements of the Act and the rules and regulations of the Commission thereunder; and

C-1-4

(b) nothing came to such counsel’s attention that caused such counsel to believe that:

(A) the Registration Statement, when it became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading,

FORM OF OPINION OF SWISS COUNSEL

1. Each of the Transocean Swiss Entities is a corporation duly incorporated and validly existing under the laws of Switzerland and has the requisite corporate power and authority to own or lease its properties and to conduct its business, in each case in all material respects as described in the Prospectus.

2. Triton Hungary Investments 1 Limited Liability Company and Triton Financing LLC are the registered owners of 100% of the quotas in Transocean Financing.

3. Each of the Transocean Swiss Entities has all requisite corporate power and authority to enter into and perform its obligations under the Underwriting Agreement and each of the Transaction Agreements, in each case to the extent it is a party thereto, and to consummate the transactions contemplated thereunder.

4. The Underwriting Agreement and each of the Transaction Agreements and the consummation of the transactions contemplated thereunder have been duly authorized and executed by each of the Transocean Swiss Entities, in each case to the extent it is a party thereto. The execution and delivery by each of the Transocean Swiss Entities of the Underwriting Agreement and each of the Transaction Agreements, in each case to the extent it is a party thereto, and the performance by each such Transocean Swiss Entity of its obligations thereunder and the consummation of the transactions contemplated thereunder, do not violate (i) any provision of the applicable Organizational Documents of the Transocean Swiss Entities or (ii) mandatory provisions of Swiss law applicable to each such Transocean Swiss Entity.

5. As far as enforceability under the laws of Switzerland is concerned, the obligations by each Transocean Swiss Entity arising out of the Underwriting Agreement and the Transaction Agreements, in each case to the extent it is a party thereto, constitute legal, valid and binding obligations of each such Transocean Swiss Entity, enforceable against it in accordance with their respective terms.

6. No permit, consent, approval, authorization, order, registration or filing of or with any governmental agency or body is required to be obtained under Swiss law in connection with the execution and delivery of the Underwriting Agreement and each of the Transaction Agreements by the Transocean Swiss Entities, to the extent such Transocean Swiss Entity is a party thereto, the performance by the Transocean Swiss Entities of their obligations thereunder or the consummation of the transactions contemplated thereby.

7. The choice of the laws of the State of New York as the governing laws of the Underwriting Agreement, the Credit Agreement and the Promissory Note, and the choice of the laws of the State of Texas and the laws of England and Wales as the governing laws of the Omnibus Agreement, are valid choices of law under the laws of Switzerland and, in any action brought before a court of competent jurisdiction in Switzerland relating to such agreements would be recognized and applied by such court to all issues for which the proper or governing law of a contract is applicable under the conflict of laws rules of Switzerland; provided, however, that (i) such choice of law may not extend to non-contractual obligations, (ii) the content of the relevant laws of the State of New York, the State of Texas or England and Wales, as applicable, may need to be proven as a matter of fact, and (iii) a Swiss court would apply Swiss procedural rules.

The submission by the Company to the jurisdiction of the state or federal courts located in the State of Texas, as provided for in the Omnibus Agreement, is a valid submission under Swiss law. The submission by Transocean Financing pursuant to the terms of the Credit Agreement to the jurisdiction of the courts of the State of New York sitting in New York county and of the United States District Court of the Southern District of New York, and any appellate court from any such court, is a valid submission under Swiss law.

9. The courts of Switzerland will recognize as valid, and will enforce, any final and non-appealable civil judgment for a pecuniary claim obtained in a competent foreign court against any of the Transocean Swiss Entities in relation to the Underwriting Agreement and each of the Transaction Agreements to which it is a party.

10. The appointment by the Company of Transocean Partners as authorized agent upon whom process may be served in any action in the New York Courts arising out of or based on the Underwriting Agreement is a valid and effective appointment if such appointment is valid and effective under the laws of the State of New York and if no other procedural requirements are necessary in order to validate such appointment.

To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, it will not, during the period commencing on the date hereof and ending 180 days after the date of the final prospectus (the “Restricted Period)” relating to the Public Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Units beneficially owned (as such term is used in Rule 13d-3

D-1

of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), by the undersigned or any other securities so owned convertible into or exercisable or exchangeable for Common Units or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Units, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Units or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (a) transactions relating to Common Units or other securities acquired in open market transactions after the completion of the Public Offering, provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made in connection with subsequent sales of Common Units or other securities acquired in such open market transactions or (b) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of Common Units, provided that (i) such plan does not provide for the transfer of Common Units during the Restricted Period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the undersigned or the Company regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of Common Units may be made under such plan during the Restricted Period. In addition, the undersigned agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, it will not, during the Restricted Period, make any demand for or exercise any right with respect to, the registration of any Common Units or any security convertible into or exercisable or exchangeable for Common Units. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s Common Units except in compliance with the foregoing restrictions.

If the undersigned is an officer or director of the Company, (i) the Representatives agree that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of Common Units, Xxxxxx Xxxxxxx will notify the Company of the impending release or waiver, and (ii) the Company has agreed in the Underwriting Agreement to announce the impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by the Representatives hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer not for consideration and (b) the transferee has agreed in writing to be bound by the same terms described in this letter to the extent and for the duration that such terms remain in effect at the time of the transfer.

The undersigned understands that the Transocean Parties and the Underwriters are relying upon this agreement in proceeding toward consummation of the Public Offering.
