RECITALS

WHEREAS, concurrently with this Agreement, Valaris and Transocean have entered into a Business Combination Agreement as of the date hereof (as may be amended from time to time, the “Business Combination Agreement”), which provides for, among other things, the acquisition by Transocean of all of the issued and outstanding Valaris Shares in exchange for shares of Transocean with a par value of $0.10 per share (or such other par value as in effect from time to time) (the “Transocean Shares”);

WHEREAS, each Valaris Shareholder is the beneficial owner (within the meaning of Rule 13d-3 under the Exchange Act, which meaning will apply for all purposes of this Agreement whenever the term “beneficial owner” or “beneficially own” is used) of the number of Valaris Shares set forth under the heading “Owned Shares” on such Valaris Shareholder’s signature page to this Agreement (the “Owned Shares”);

WHEREAS, the Owned Shares (as defined) and any additional Valaris Shares or other voting securities of Valaris acquired by each Valaris Shareholder after the date hereof and prior to the Termination Date (as defined herein) and pursuant to which such Valaris Shareholder has or may have (provided the Valaris Shares have been duly registered in Valaris’ share register, including through Cede & Co as nominee, enabling such Valaris Shareholder to vote as a beneficial owner) the right to vote such Valaris Shares or other voting securities, including by purchase, as a result of a stock dividend, stock split, recapitalization, combination, reclassification, exchange or change of such Valaris Shares, upon exercise or conversion of any securities or warrants, or upon the vesting of equity awards are referred to in this Agreement as the “Covered Shares”, in each case, solely to the extent beneficially owned by such Valaris Shareholder at the relevant time;

WHEREAS, as a condition and inducement to Transocean’s willingness to enter into the Business Combination Agreement and to proceed with the transactions contemplated thereby, including the Business Combination, Transocean and the Valaris Shareholders are entering into this Agreement; and

WHEREAS, each Valaris Shareholder acknowledges that Transocean is entering into the Business Combination Agreement in reliance on the representations, warranties, covenants and other agreements of such Valaris Shareholder set forth in this Agreement, and would not enter into the Business Combination Agreement if such Valaris Shareholder did not enter into this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements herein contained, and intending to be legally bound hereby, Transocean and each Valaris Shareholder hereby agree as follows:

Section 1. Agreement to Vote. From and after the date hereof until the termination of this Agreement in accordance with Section 3, at any meeting of the shareholders of Valaris (however called), and at every postponement, adjournment or reconvening thereof, each Valaris Shareholder shall procure that, in each case as of the record date for the relevant general meeting of shareholders of Valaris, (y) such Valaris Shareholder shall cause its Covered Shares to be counted as present or represented thereat for purposes of calculating a quorum and (z) such Valaris Shareholder’s Covered Shares shall be voted at such meeting (or adjournment, postponement or reconvening thereof) by granting and delivering a valid proxy or other instructions necessary to vote such Covered Shares at such meeting (or adjournment, postponement or reconvening thereof), no later than the date indicated in the notice of meeting or proxy materials of such meeting (or adjournment, postponement or reconvening thereof) as being the date until which proxy or other instructions may be validly given for the meeting, as follows:

(a) in favor of the Valaris Transaction Resolution and in favor of any other matter necessary to the consummation of the transactions contemplated by the Business Combination Agreement;

(b) in favor of any proposal to postpone, adjourn or reconvene such meeting to or on a later date (A) to solicit additional proxies if Valaris will not receive sufficient proxies for the purpose of obtaining the Valaris Required Approval, whether or not a quorum is present, (B) if Valaris will not have enough Valaris Shares represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the Valaris Meeting or (C) if such postponement, adjournment or reconvening is required by Applicable Law or a Governmental Authority;

(c) against any Acquisition Proposal with respect to Valaris, or any other transaction, proposal, agreement or action made in opposition to adoption or approval of the Valaris Transaction Resolution;

(d) against any action or agreement with respect to Valaris that would reasonably be expected to result in a breach of any representation, warranty, covenant or obligation of Valaris in the Business Combination Agreement, or of such Valaris Shareholder in this Agreement; and

(e) against any other action, agreement, transaction or proposal involving Valaris or any of its Subsidiaries that would reasonably be expected to prevent, materially interfere with, materially delay or materially impair the timely consummation of the Business Combination or the fulfillment of any of the conditions set forth in Article 6 (Conditions Precedent) of the Business Combination Agreement.

Each Valaris Shareholder shall not revoke or modify the instructions granted pursuant to the immediately preceding sentence prior to the Termination Date, except, in each case, as may be necessary to comply with the voting obligations set forth in this Section 1. Notwithstanding anything to the contrary in this Agreement, if at any time prior to the Termination Date a Governmental Authority of competent jurisdiction enters an order restraining, enjoining or otherwise prohibiting any Valaris Shareholder from taking any action pursuant to this Section 1, then the obligations of such Valaris Shareholder set forth in this Section 1 shall be of no force and effect for so long as such order is in effect and solely to the extent such order restrains, enjoins or otherwise prohibits such Valaris Shareholder from taking any such action.

Notwithstanding anything in this Agreement to the contrary, each Valaris Shareholder shall remain free to vote its Covered Shares with respect to any matter not covered by this Section 1 in any manner that such Valaris Shareholder deems appropriate. For the avoidance of doubt, nothing in this Agreement shall require any Valaris Shareholder to vote (or cause to be voted) any of the Covered Shares in any manner with respect to an amendment, modification or supplement to the Business Combination Agreement that could result in the termination of this Agreement pursuant to Section 3(d).

Section 2. Inconsistent Agreements. Except as contemplated by this Agreement, each Valaris Shareholder hereby represents, covenants and agrees that such Valaris Shareholder has not, nor has any entity with voting authority over the Covered Shares, (a) entered into, or shall enter into at any time prior to the Termination Date, any voting agreement or voting trust with respect to its Covered Shares or (b) granted, nor shall grant at any time prior to the Termination Date, a proxy or power of attorney with respect to its Covered Shares, which has not subsequently been revoked or which is inconsistent with the obligations of such Valaris Shareholder pursuant to this Agreement.

Section 3. Termination. This Agreement shall terminate upon the earliest of (a) the Effective Time, (b) the termination of the Business Combination Agreement in accordance with its terms, (c) the time at which an Adverse Recommendation Change is effected by the Valaris Board or any committee thereof in accordance with the terms of the Business Combination Agreement, (d) the time at which the Business Combination Agreement is amended, modified or supplemented in a manner that (A) decreases the consideration payable to any Valaris Shareholder or any other Valaris shareholder pursuant to the terms of the Business Combination Agreement, (B) changes the form of consideration to be received by any Valaris Shareholder or any other Valaris shareholder or (C) otherwise adversely affects the interests of any Valaris Shareholder or any other Valaris shareholder or does not impact or otherwise affect the Valaris shareholders in the same manner. or (e) written notice of termination of this Agreement by Transocean to the Valaris Shareholders (such earliest date being referred to herein as the “Termination Date”); provided, that the provisions set forth in Sections 7, and 9 through 23 shall survive the termination of this Agreement; provided, further that no such termination will relieve any party hereto from any liability for any willful and material breach of this Agreement occurring prior to such termination.

Section 4. Representations and Warranties of the Valaris Shareholders. Each Valaris Shareholder hereby represents and warrants, solely with respect to such Valaris Shareholder, to Transocean as follows:

This Agreement has been duly and validly executed and delivered by such Valaris Shareholder and, assuming due authorization, execution and delivery by Transocean, constitutes a legal, valid and binding obligation of such Valaris Shareholder, enforceable against it, him or her in accordance with its terms, except as enforcement may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other Applicable Laws of general application relating to or affecting rights of creditors and equitable remedies, including specific performance, are discretionary and may not be ordered.

(c) Except for the applicable requirements of the Exchange Act, (i) no filing with, and no permit, authorization, consent or approval of, any Governmental Authority is necessary on the part of such Valaris Shareholder for the execution, delivery and performance of this Agreement by such Valaris Shareholder or the consummation by such Valaris Shareholder of the transactions contemplated hereby, other than as contemplated by the Business Combination Agreement, and (ii) neither the execution, delivery or performance of this Agreement by such Valaris Shareholder, nor the consummation by such Valaris Shareholder of the transactions contemplated hereby, nor compliance by such Valaris Shareholder with any of the provisions hereof shall (A) conflict with or violate, any provision of the organizational documents of the Valaris Shareholder (if the Valaris Shareholder is an entity), (B) result in any breach or violation of, or constitute a default (or an event which, with notice or lapse of time or both, would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, or result in the creation of an Encumbrance (other than a Permitted Encumbrance) on any property or asset of such Valaris Shareholder pursuant to, any Contract to which such Valaris Shareholder is a party or by which such Valaris Shareholder or any properties or assets of such Valaris Shareholder is bound or affected or (C) violate any order, writ, injunction, decree, statute, rule or regulation applicable to such Valaris Shareholder or any of such Valaris Shareholder’s properties or assets, except, in the case of each of sub-clause (i) and (ii), as would not restrict, prohibit or materially impair the performance by such Valaris Shareholder of its obligations under this Agreement.

(d) As of the date hereof, there are no Proceedings pending or, to the knowledge of such Valaris Shareholder, threatened against such Valaris Shareholder or any of its or his affiliates (such term as used herein, having the same meaning set forth in the Business Combination Agreement) that would materially impair the ability of such Valaris Shareholder to perform its obligations under this Agreement or consummate the transactions contemplated by this Agreement in a timely manner.

Section 5. Representations and Warranties of Transocean. Transocean hereby represents and warrants to the Valaris Shareholder as follows:

(a) Transocean is an Swiss corporation, incorporated, validly existing and in good standing under the Applicable Swiss Laws.

Section 14. Governing Law. This Agreement and all claims and causes of action based upon, arising out of or in connection herewith shall be governed by, and construed in accordance with, the Laws of the State of Delaware, without regard to Laws that may be applicable under conflicts of laws principles (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware.

Section 15. Submission to Jurisdiction. Any Action based upon, arising out of or related to this Agreement, or the transactions contemplated hereby, shall be brought and determined exclusively in the Court of Chancery of the State of Delaware or, if such court declines to exercise jurisdiction, any federal or state court located in the State of Delaware, and each of the parties irrevocably submits to the exclusive jurisdiction of each such court in any such Action, waives any objection it may now or hereafter have to personal jurisdiction, venue or to convenience of forum, agrees that all claims in respect of the Action shall be heard and determined only in any such court, and agrees not to bring any Action arising out of or relating to this Agreement or the transactions contemplated hereby in any other court.

Each party agrees that it shall not oppose the granting of specific performance and other equitable relief on the basis that the other party has an adequate remedy at Law or that an award of specific performance is not an appropriate remedy for any reason at Law or equity.

Section 18. Severability.

(a) If any one or more of the provisions (or any part thereof) of this Agreement is determined to be invalid, illegal or unenforceable by any Governmental Authority, such provision or provisions (or part or parts thereof) shall be, and shall be conclusively deemed to be, as to such jurisdiction, severable from the balance of this Agreement and:
