March 2, 2012

Mr. Xxxxxx Xxxx

Dear Rob:

This letter agreement (the “Agreement”) states the terms and conditions applicable to the termination of your employment with Transocean. All references in this Agreement to “Transocean” shall mean Transocean Offshore Deepwater Drilling, Inc. (“TODDI”), its parent, subsidiaries, affiliates and related entities.

Resignation and Termination. You previously resigned as Vice President, Controller & Principal Accounting Officer, and from any and all other officer or director positions with Transocean, effective January 25, 2012. Your employment with Transocean shall terminate on March 15, 2012 (the “Termination Date”).

Severance Pay. You shall receive a lump sum cash payment equal to $350,000, less applicable withholding (the “Compensation”), subject to and contingent upon your timely execution without revocation of the supplemental waiver and release agreement attached hereto as Annex I (the “Waiver and Release”). In order to be considered as timely and valid for purposes of this Agreement, the Waiver and Release must be signed by you and delivered to Transocean no earlier than the Termination Date and no later than 21 days after the Termination Date, without revocation. The Compensation shall be payable in a lump sum thirty (30) days after the Termination Date. Any right you may have to payment arising in connection with earned but unused vacation time will be fully satisfied by the payment of the Compensation.

Bonus. Subject to and contingent upon your timely execution without revocation of the Waiver and Release, you will also receive a cash payment (the “2012 Bonus”) in an amount equal to $35,960. Payment of your 2012 Bonus, less applicable withholding, will be made simultaneously with the payment of Compensation thirty (30) days after the Termination Date and will be in lieu of your participation in the Cash Bonus Plan for the 2012 calendar year.

Long-Term Incentive Plan Awards. You will not receive any additional awards under the LTIP. You should refer to the applicable award letters as to the specific treatment of any awards previously granted to you under the LTIP. In addition, the following terms shall apply to any awards under the LTIP that remain outstanding as of the Termination Date:

HOU01:1211745.11

- 1 -

(A) Restricted Stock Units. All Restricted Stock Units (“RSUs”) previously granted to you under the LTIP will be treated as if Transocean terminated your employment for the Convenience of the Company (as defined by and determined in accordance with the terms of the LTIP and the applicable award agreement) on the Termination Date, provided that, such treatment is subject to and contingent upon your timely execution without revocation of the Waiver and Release. For the avoidance of doubt, the following provides details regarding the status of your outstanding RSU awards if you continue to be employed by Transocean until March 15, 2012:

Grant Date	RSUs Granted	Vested Per Schedule as of March 15, 2012	Accelerated Vesting on March 15, 2012*
11/17/2010	6,275	2,091	4,184
2/10/2011	1,997	665	1,332
12/1/2011	9,869	0	9,869

*Your accelerated RSUs will be settled 30 days following your Termination Date, contingent on execution without revocation of the Waiver and Release.

(B) Non-qualified Stock Options. All non-qualified stock options (“NQ Options”) previously granted to you under the LTIP will be treated as if Transocean terminated your employment for the Convenience of the Company (as defined by and determined in accordance with the terms of the LTIP and the applicable award agreement) on the Termination Date, provided that, such treatment is subject to and contingent upon your timely execution without revocation of the Waiver and Release. For the avoidance of doubt, the following provides details regarding the status of your NQ Options if you continue to be employed by Transocean until March 15, 2012:

Grant Date	Exercise Price (in U.S. dollars)	Number Awarded	Vested on March 15, 2012	Forfeited as of March 15, 2012	Exercise Period Ends
2/10/2011	$ 78.76	3,929	1,309	2,620	March 14, 2013

HOU01:1211745.11

- 2 -

(C) Contingent Deferred Units. All contingent deferred units (“CDUs”) previously granted to you under the LTIP will be treated as if Transocean terminated your employment for the Convenience of the Company (as defined by and determined in accordance with the terms of the LTIP and the applicable award agreement) on the Termination Date, provided that, such treatment is subject to and contingent upon your timely execution without revocation of the Waiver and Release. You will receive a pro-rata portion of the CDUs that are outstanding as of your Termination Date, which will remain subject to the applicable performance contingency. For the avoidance of doubt, the following provides details regarding the status of your outstanding CDUs if you continue to be employed by Transocean until March 15, 2012:

Grant Date	CDUs Held	Forfeited as of Termination Date	Outstanding as of Termination Date	Earned
2/10/2011	1,997	1,242	755	TBD*

*In the event of a termination of employment for the Convenience of the Company, you receive a pro-rata portion of outstanding CDUs. The pro-rata portion of the CDUs determined above is calculated by multiplying the number of CDUs held by a fraction, the numerator of which is the number of calendar days of employment during the performance cycle after the grant date (399) and the denominator of which is the total number of calendar days in the performance cycle after the grant date (1055). The determination of the vested awards will be made within the first 60 days of 2014, and the distribution of the vested portion of the award will be made on March 15, 2014.

Benefits.

(A) Retirement Plans. Following the Termination Date, you will no longer be able to participate in the Transocean retirement plans, including the U.S. Savings Plan, U.S. Retirement Plan and the Transocean Management, Ltd. Pension Plan (the “Plans”). The payment of your benefit under the Plans will be made in accordance with the applicable terms of that plan.

(B) Welfare Benefits. You shall continue to receive coverage under Transocean’s expatriate group medical insurance program at Transocean’s expense until July 31, 2012 and Transocean will make available to you an opportunity to elect COBRA health continuation coverage.

You irrevocably and unconditionally release, acquit, and forever discharge Transocean, and any predecessors or successors (collectively, the “Transocean Group”), and its and their past and present officers, directors, attorneys, insurers, agents, servants, suppliers, representatives, employees, affiliates, subsidiaries, parent companies, partners, predecessors and successors in interest, assigns and benefit plans (except with respect to vested benefits under such plans), and any other persons or firms for whom the Transocean Group could be legally responsible (collectively, “Released Parties”), from any and all claims, liabilities or causes of action, whether known or now unknown to you, arising from or related in any way to your employment or termination of your employment with the Transocean Group and/or any of the Released Parties and occurring through the date you sign and return this Agreement, other than claims arising under the Age Discrimination in Employment Act, as amended, and the Older Workers Benefit Protection Act, which are addressed only in the Waiver and Release.

17.	Choice of Law. This Agreement shall be interpreted and construed in accordance with and shall be governed by the laws of the State of Texas, notwithstanding any conflicts of law principles which may refer to the laws of any other jurisdiction.

18.

Taxes.

Transocean will have the right to deduct from all benefits and payment made under this Agreement any and all taxes required by law to be paid or withheld with respect to such benefits or payments.

19.	Section 409A.

The Agreement is intended to comply with the provisions of Section 409A and applicable Treasury authorities and, wherever possible, shall be construed and interpreted to ensure that any payments that may be paid, distributed provided, reimbursed, deferred or settled under this Agreement will not be subject to any additional taxation under Section 409A. This Section 19 does not create an obligation on the part of Transocean to modify the Agreement in the future and does not guarantee that the amounts or benefits owed under the Agreement will not be subject to interest and penalties under Code Section 409A. Notwithstanding any provision of the Agreement to the contrary, the following provisions shall apply for purposes of complying with Section 409A:

(i) Pursuant to the applicable standards regarding termination from employment for purposes of Section 409A and the applicable Treasury Regulations under 1.409A-1(h)(1)(ii), you and Transocean acknowledge that you will have a separation from service for purposes of determining the timing of payment of deferred compensation to which you are entitled as of the Termination Date.

(ii) The provisions of Section 409A of the Internal Revenue Code of 1986, as amended, do not apply to the Compensation or the 2012 Bonus since this amount qualifies for the short-term deferral exception described in Treasury Regulation §1.409A-1(b)(4), in addition to the separation pay exemption as it does not exceed the separation pay plan limits described in Treasury Regulation §1.409A-1(b)(9).

(iii) Continued medical benefits are intended to satisfy the exemption for medical expense reimbursements under Treasury Regulation Section 1.409A-1(b)(9)(v)(B).

20.

Notices provided for in this Agreement shall be in writing and shall either be personally delivered by hand or sent by: (i) mail service, postage prepaid, properly packaged, addressed and deposited with the mail service system; (ii) via facsimile transmission or electronic mail if the receiver acknowledges receipt; or (iii) via Federal Express or other expedited delivery service provided that acknowledgment of receipt is received and retained by the deliverer and furnished to the sender.
