12.4 The Parent shall retain the Information Agent to reconcile entitlements under this Clause (Early Consent), whose decision with respect to such entitlements shall be final and binding, absent manifest error.

13. ACCESSION

13.1 Any holder of a Debt Instrument who wishes to become a Supporting Creditor may accede to this Agreement by delivering a duly completed and executed Accession Letter to the Parent and the legal counsel to the Ad Hoc Committee in accordance with Clause 19 (Notices).

14.1 Without prejudice to the applicable requirements of the Debt Instrument Agreements, each Supporting Creditor agrees that from the Effective Date until this Agreement is terminated in accordance with Clause 16 (Termination), it shall not sell, assign, transfer, or otherwise dispose of to any Person any ownership (including any beneficial ownership) in the Parent Scheme Claims, DRH Scheme Claims, DFH Scheme Claims or DOV Scheme Claims or any option thereon or any right or interest therein (including by granting any proxies or depositing any interests in such Claims into a voting trust or by entering into a voting agreement (other than this Agreement) with respect to such Claims) (a "Transfer" and the proposed transferee a "Creditor Transferee") unless in compliance with the terms of this Clause 14.

14.2 Before completing any Transfer, the Supporting Creditor transferor shall, unless the Creditor Transferee is already a Party, procure that the Creditor Transferee delivers a duly executed Accession Letter to the Parent and the Ad Hoc Committee. No Transfer shall be effective until notification of such Transfer and a copy of the executed Accession Letter is received by the Parent and the Ad Hoc Committee (such Transfer, a "Permitted Transfer" and such party to such Permitted Transfer, a "Permitted Transferee"). Any Transfer made in violation of this Clause 14 shall be void ab initio.

14.3 Before completing any Transfer on or after the date falling ten (10) Business Days before the relevant Scheme Meeting, the Supporting Creditor transferor shall, unless the Creditor Transferee is already a Party, vote by proxy all relevant Claims in favor of the relevant Scheme.

10

Claims so acquired and held (i.e., not as a part of a short transaction) shall be subject to the terms of this Agreement), (ii) a Qualified Marketmaker that acquires any Claims from a Supporting Creditor with the purpose and intent of acting as a Qualified Marketmaker for such Claims, shall not be required to execute and deliver to the Parent and the Ad Hoc Committee an Accession Letter or otherwise agree to be bound by the terms and conditions set forth in this Agreement if such Qualified Marketmaker transfers such Claims (by purchase, sale, assignment, participation, or otherwise) within five (5) Business Days of its acquisition to a Supporting Creditor or Permitted Transferee and the transfer otherwise is a Permitted Transfer; and (iii) to the extent any Party is acting solely in its capacity as a Qualified Marketmaker, it may Transfer any ownership interests in the Claims that it acquires from a holder of Claims that is not a Supporting Creditor ("Non-RSA Claims") to a transferee that is not a Supporting Creditor at the time of such Transfer without the requirement that the transferee be or become a signatory to this Agreement or execute an Accession Letter. Notwithstanding anything contain herein to the contrary (including, but not limited to, Clause 14.3 herein), a Qualified Marketmaker shall not be required to vote any of its Non-RSA Claims in favor of the relevant Scheme. A Qualified Marketmaker shall be entitled to split its vote between Non-RSA Claims and Claims it may hold as a Supporting Creditor.

14.5 This Agreement shall not preclude the Supporting Creditors from acquiring additional Claims. Any Claims acquired by a Supporting Creditor shall automatically and immediately upon acquisition by a Supporting Creditor be deemed subject to the terms of this Agreement regardless of when or whether notice of such acquisition is given to the Company as set forth above), other than any Claims acquired by such Supporting Creditor in its capacity as a Qualified Marketmaker.

14.6 For the avoidance of doubt, following a Permitted Transfer by a Supporting Creditor of all of its interests in the Claims, a Supporting Creditor shall immediately cease to be a Supporting Creditor for purposes of this Agreement and such Supporting Creditor shall cease to be bound by this Agreement, provided, however, that the provisions of Clause 17 (Surviving Obligations) and Clause 3 (Undertakings) shall continue to apply to such Person as if such Person had remained a Supporting Creditor.

15. PUBLICITY AND DISCLOSURES

15.1 The Parent may issue any public announcement regarding this Agreement and the Restructuring after giving reasonable notice to the Ad Hoc Committee, and such notice shall include a copy of the relevant public announcement. No other Party shall make any public announcement regarding this Agreement or the Restructuring unless such announcement is in Agreed Form. If an announcement is required by applicable Law, regulation or listing rules, the Party proposing to make the disclosure shall, to the extent legally possible, and on reasonable notice in the circumstances, consult with the Parent and counsel to the Ad Hoc Committee as to the form, content, and timing of the proposed announcement.

(i) other than for the purpose of implementing the Restructuring in accordance with the terms of this Agreement, any Insolvency Proceeding is opened in respect of the Parent or any other Group Member that is a Significant Subsidiary of the Parent in any jurisdiction; provided however, that, the filing of an involuntary proceeding under section 303 of the Bankruptcy Code or any similar creditor initiated proceeding under any other applicable foreign law with respect to any Group Member that is a Significant Subsidiary of the Parent will not constitute an Insolvency Proceeding for purposes of this provision until an order for relief or similar determination has been entered or rendered with respect to such proceeding;

(ii) if the Cayman Court, other than with respect to the DRH Scheme Meeting, (a) refuses to convene any of the Scheme Meetings (unless such entity is the subject of a Consensual Restructuring, or such defect is remedied through a modification of the Scheme in accordance with this Agreement), or (b) refuses to sanction either the Parent Scheme, the DFH Scheme or the DOV Scheme (unless such entity is the subject of a Consensual Restructuring);

(vii) the Parent or any Subsidiary Borrower commits a Material Breach of this Agreement, and where such breach is capable of being remedied, the Parent or relevant Subsidiary Borrower, after receipt of written notice of such breach from the Majority Supporting Lenders, has failed to remedy such a breach by the earlier of (a) within 14 days of the receipt of written notice from the Majority Supporting Lenders, and (b) the Business Day immediately preceding the Restructuring Effective Date;

(viii) if within thirty days following an official body of competent jurisdiction (including any court of competent jurisdiction), entering a final non-appealable Order permanently restraining, enjoining or otherwise prohibiting the implementation, consummation or closing of the Restructuring, such Order has not been withdrawn or it is not subject to reconsideration by the issuer of such Order, provided that if failure to terminate this Agreement before such date would cause any Party to be in breach of the Order, this Agreement shall be terminated immediately;

(ix) if the Parent and its Significant Subsidiaries are unable to continue to manage their operations in the ordinary course of business;

(x) the Parent is in breach of its obligation under any fee arrangement to pay any professional fees, costs and expenses incurred by the Ad Hoc Committee and the Parent has failed to remedy such breach within 14 days of written notice of such breach being provided to the Parent, provided that termination under this sub-clause shall not limit the Parent's liability to pay those professional fees, costs and expenses; and

(xi) if a Specified Event of Default has occurred.

(d) by any Supporting Creditor giving written notice to the Parent, to terminate with respect to such Supporting Creditor only, if the Parent and the Majority Supporting Lenders amend or waive any term of this Agreement pursuant to Clause 23 (Amendments and Waivers) and the relevant amendment or waiver:

Capitalized terms used but not otherwise defined herein shall have the meaning ascribed to such terms in the Restructuring Agreement to which this Term Sheet is attached.

THIS TERM SHEET DOES NOT CONSTITUTE (NOR SHALL IT BE CONSTRUED AS) AN OFFER WITH RESPECT TO ANY SECURITIES OR A SOLICITATION OF ACCEPTANCES OR REJECTIONS AS TO ANY PLAN, IT BEING UNDERSTOOD THAT SUCH A SOLICITATION, IF ANY, ONLY WILL BE MADE IN COMPLIANCE WITH APPLICABLE PROVISIONS OF SECURITIES, BANKRUPTCY AND/OR OTHER APPLICABLE LAWS.

THE TRANSACTIONS DESCRIBED HEREIN WILL BE SUBJECT TO THE COMPLETION OF DEFINITIVE DOCUMENTS INCORPORATING THE TERMS SET FORTH HEREIN AND THE CLOSING OF ANY TRANSACTION SHALL BE SUBJECT TO THE TERMS AND CONDITIONS SET FORTH IN SUCH DEFINITIVE DOCUMENTS.

Shareholders Agreement Under the terms of the Restructuring Agreement, on the Effective Date, all Parent Scheme Claim Holders will be entitled to an amount of the post-Effective Date ordinary shares of Parent (the "Shares").^{2 3} As part of the Restructuring, the DOV/DFH Lenders and, to the extent they elect to do so, all other Parent Scheme Claim Holders, will have entered into a shareholders agreement (the "Shareholders Agreement")⁴ governing the rights of the shareholders party thereto in connection with the affairs of the Companies on substantially the terms set forth in this Term Sheet and otherwise in form and substance satisfactory to

________________________

1. In addition to the terms described herein, the parties have agreed: (1) TMS, Parent and each of its subsidiaries and the Lenders will provide mutual releases, which will be included in the Restructuring Agreement, provided that the agreed indemnification obligations of Parent in favor of TMS will be excluded from any release provided for hereunder and (2) with respect to the indemnification of directors and officers prior to the restructuring, (i) indemnification will only be provided for claims covered by Parent's $400 million D&O insurance policy, (ii) Parent will indemnify directors and officers in excess of $400 million, and (iii) no indemnification will be provided if the D&O insurance is not available as a result of a willful failure to disclose to the insurance provider.

2. Parent Scheme Claims Holders will have the option to be issued a second class of ordinary shares of the Parent that are the same as the Shares except they will be non-marginable and convertible into the Shares.

3. It is expected that the Shares will be issued pursuant to the exemption from registration under Section 3(a)(10) of the Securities Act, that the transactions will not involve any shell companies (with the meaning of the Securities Act) and is intended that the Shares will be freely tradable by persons who are not affiliates of Parent without Rule 144 holdings period or volume or manner of sale limitations/restrictions.

4. In order to address potential group concerns under Section 13 of the Securities Exchange Act of 1934, the: (1) Shareholders Agreement may be restyled as a series of identical two-party "governance agreements" between each Shareholder Party and the Companies and (2) provisions in the Shareholders Agreement that relate to voting or disposition of equity would be placed in the Amended and Restated Memorandum and Articles of the Parent, in each case in a manner not expected to materially affect the rights and obligations of the Shareholder Parties and the Companies under the Restructuring Agreement, the Shareholders Agreement or otherwise.

	the Majority Supporting Lenders and TMS Offshore ("TMS"). Existing subsidiaries of Parent will also be required to enter into the Shareholders Agreement (the "Management Parties"). The organizational documents of each newly formed subsidiary will provide that such newly formed subsidiary may not take any action in contravention of the Shareholders Agreement.
	References in this Term Sheet to "Lender Shareholder Parties" shall be to (i) the Parent Scheme Claim Holders (including any Parent Scheme Claim Holders, that are not DOV/DFH Lenders) initially party to the Shareholders Agreement and (ii) each transferee of Shares from such initial parties other than (A) any Company (in its capacity as a holder of Shares), (B) TMS and each affiliate thereof, and (C) officers or employees of any of the Companies (or such person's relatives, trusts or other related parties).

	Identification of Lender Appointing Persons. Each "Lender Appointing Person" will be determined on the date that is two business days after distribution of scheme consideration (the "Director Appointment Date") as stated below. Until the Director Appointment Date, the Board will consist of the then-current directors (the "Interim Board").

	Prior to the Director Appointment Date and the appointing of the three Lender Directors, the Companies cannot take any action if such action would otherwise

In addition, so long as a Lender Appointing Person has a right to appoint a Lender Director, but does not appoint an officer or employee of such Lender Appointing Person to serve as a Lender Director, such Lender Appointing Person shall have the right, exercisable by delivering notice to Parent, to designate one (1) non-voting observer to attend any meetings of the Board (or any committee thereof).

3.           Independent Outside Director (IO)

3.1.          No material[12] connection to the company other than a board seat.

Footnotes:

[1]The definition of officer will generally follow that of a "Section 16 officer" (officers subject to Section 16 of the Securities and Exchange Act of 1934) and includes the chief executive, operating, financial, legal, technology, and accounting officers of a company (including the president, treasurer, secretary, controller, or any vice president in charge of a principal business unit, division, or policy function). Current interim officers are included in this category. For private companies, the equivalent positions are applicable. A non-employee director serving as an officer due to statutory requirements (e.g. corporate secretary) will be classified as an Affiliated Outsider under 2.18: "Any material relationship with the company." However, if the company provides explicit disclosure that the director is not receiving additional compensation in excess

of $10,000 per year for serving in that capacity, then the director will be classified as an Independent Outsider.

[2]          "Affiliate" includes a subsidiary, sibling company, or parent company. ISS uses 50 percent control ownership by the parent company as the standard for applying its affiliate designation.

[3]          Includes any former CEO of the company prior to the company's initial public offering (IPO).

[4]          When there is a former CEO of a special purpose acquisition company (SPAC) serving on the board of an acquired company, ISS will generally classify such directors as independent unless determined otherwise taking into account the following factors: the applicable listing standards determination of such director's independence; any operating ties to the firm; and the existence of any other conflicting relationships or related party transactions.

[5]          ISS will look at the terms of the interim officer's employment contract to determine if it contains severance pay, long-term health and pension benefits, or other such standard provisions typically contained in contracts of permanent, non-temporary CEOs. ISS will also consider if a formal search process was under way for a full-time officer at the time.

[6]          "Immediate family member" follows the SEC's definition of such and covers spouses, parents, children, step-parents, step-children, siblings, in-laws, and any person (other than a tenant or employee) sharing the household of any director, nominee for director, executive officer, or significant shareholder of the company.

[7]          Professional services can be characterized as advisory in nature, generally involve access to sensitive company information or to strategic decision-making, and typically have a commission- or fee-based payment structure. Professional services generally include, but are not limited to the following: investment banking/financial advisory services; commercial banking (beyond deposit services); investment services; insurance services; accounting/audit services; consulting services; marketing services; legal services; property management services; realtor services; lobbying services; executive search services; and IT consulting services. The following would generally be considered transactional relationships and not professional services: deposit services; IT tech support services; educational services; and construction services. The case of participation in a banking syndicate by a non-lead bank should be considered a transactional (and hence subject to the associated materiality test) rather than a professional relationship. "Of Counsel" relationships are only considered immaterial if the individual does not receive any form of compensation (in excess of $10,000 per year) from, or is a retired partner of, the firm providing the professional service. The case of a company providing a professional service to one of its directors or to an entity with which one of its directors is affiliated, will be considered a transactional rather than a professional relationship. Insurance services and marketing services are assumed to be professional services unless the company explains why such services are not advisory.

[8]          A material transactional relationship, including grants to non-profit organizations, exists if the company makes annual payments to, or receives annual payments from, another entity exceeding the greater of $200,000 or 5 percent of the recipient's gross revenues, in the case of a company which follows NASDAQ listing standards; or the greater of $1,000,000 or 2 percent of the recipient's gross revenues, in the case of a company which follows NYSE listing standards. In the case of a company which follows neither of the

preceding standards, ISS will apply the NASDAQ-based materiality test. (The recipient is the party receiving the financial proceeds from the transaction).

[9]          Dissident directors who are parties to a voting agreement pursuant to a settlement or similar arrangement may be classified as independent outsiders if an analysis of the following factors indicates that the voting agreement does not compromise their alignment with all shareholders' interests: the terms of the agreement; the duration of the standstill provision in the agreement; the limitations and requirements of actions that are agreed upon; if the dissident director nominee(s) is subject to the standstill; and if there any conflicting relationships or related party transactions.

[10]          Interlocks include: executive officers serving as directors on each other's compensation or similar committees (or, in the absence of such a committee, on the board); or executive officers sitting on each other's boards and at least one serves on the other's compensation or similar committees (or, in the absence of such a committee, on the board).

[11]          The operating involvement of the founder with the company will be considered; if the founder was never employed by the company, ISS may deem him or her an independent outsider.

[12]          For purposes of ISS's director independence classification, "material" will be defined as a standard of relationship (financial, personal or otherwise) that a reasonable person might conclude could potentially influence one's objectivity in the boardroom in a manner that would have a meaningful impact on an individual's ability to satisfy requisite fiduciary standards on behalf of shareholders.

This Term Sheet also outlines the principal terms of grants of equity in Parent to TMS. This Term Sheet is strictly private and confidential. Capitalized terms used but not otherwise defined in this Term Sheet shall have the meanings specified in Appendix 1 hereto or the Restructuring Agreement to which this Term Sheet is attached.

THIS TERM SHEET DOES NOT CONSTITUTE (NOR SHALL IT BE CONSTRUED AS) AN OFFER WITH RESPECT TO ANY SECURITIES OR A SOLICITATION OF ACCEPTANCES OR REJECTIONS AS TO ANY PLAN, IT BEING UNDERSTOOD THAT SUCH A SOLICITATION, IF ANY, ONLY WILL BE MADE IN COMPLIANCE WITH APPLICABLE PROVISIONS OF SECURITIES, BANKRUPTCY AND/OR OTHER APPLICABLE LAWS.

THE TRANSACTIONS DESCRIBED HEREIN WILL BE SUBJECT TO THE COMPLETION OF DEFINITIVE DOCUMENTS INCORPORATING THE TERMS SET FORTH HEREIN AND THE CLOSING OF ANY TRANSACTION SHALL BE SUBJECT TO THE TERMS AND CONDITIONS SET FORTH IN SUCH DEFINITIVE DOCUMENTS.

Overview of the MSA	Each member of the Group, including the Parent, and TMS will enter into the MSA to agree to the principal terms of the engagement of TMS which, among other things, will also include the following elements (as described in more detail below):
		(a)	The engagement of TMS to provide services to the Group being specified in a separate Individual Management Agreement to be entered into by each respective subsidiary and TMS and contain the terms and conditions listed in Appendix 2 hereto.
		(b)	In consideration for rendering the services described in the MSA, the Group will pay certain fees to TMS as provided below.
Individual Management Agreement		On the MSA Effective Date, each Rig Owning Entity, as applicable, will enter into a Management Agreement on substantially the terms set out in Appendix 2.

	year renewable extensions upon approval of the Board of Directors of Parent 90 days prior to the expiration of the prior term (the "Term").
Fixed Annual Cash Payments	Parent will pay $15.5 million in fixed annual cash payments paid monthly, (the "Fixed Annual Cash Payments"), plus reasonable out-of-pocket and travel expenses in connection with the performance of the obligations under the MSA and consistent with the policies of the Group at the time of the transaction, which shall be invoiced monthly and supported by relevant documentation. For the avoidance of doubt, the Fixed Annual Cash Payments shall not be reduced by Parent in the event the Group requests lesser services than are required to be performed under the MSA.

		1.	Uptime

			(c)	Maximum Amount of Bonus Fee with respect to the EBITDA Margin metric per year: $2 5 million

			(c)	A fee of $2,000 per person per day for superintendent attendance offshore provided by TMS.
Termination Fee	Fee for termination by Parent without Cause (as defined below) of either (x) $150 million, which amount shall be reduced rateably over the term of the Management Agreement or (y) $30 million, whichever is greater (the "Convenience Termination Fee").

The Security Deposit shall be refundable to Parent at the end of the Term.

The Parent shall immediately replenish the Security Deposit so that it remains at $5 million Notwithstanding anything herein to the contrary, if any member of Group owes TMS greater than the amount of the Security Deposit, the Group shall still owe any difference between the amount owed and the Security Deposit, payable within five days of such payment being due.

	Termination for Cause.

If TMS provides a written notice to the Parent within such five-business day period (an "Objection Notice") pursuant to which a director of TMS certifies to the Parent that Cause does not exist, then (a) the Parent may rescind such Notice of Termination for Cause or (b) terminate the MSA following the expiration of such five-business day period subject to complying with the procedures described below under "Dispute Procedures."

		(a)	The Parent and TMS shall refer the dispute to binding arbitration pursuant to the arbitration provisions of the MSA described below under "Governing law and jurisdiction."
		(b)	If the arbitrators (acting by majority) rule that Cause did exist, then (I) no further sums shall be due by the Parent under the MSA and (II) all amounts on deposit in the Escrow Account shall be disbursed to the Parent.
		(c)	If the arbitrators (acting by majority) rule that Cause did not exist, then (I) the Parent will pay to TMS an amount equal to the Convenience Termination Fee calculated as of the date of termination of the MSA less the amounts on deposit in the Escrow Account and (II) all amounts on deposit in the Escrow Account shall be disbursed to TMS.

Sch. 8-5

	Notwithstanding the foregoing, any conviction of Mr. Xxxxxx Xxxxxxxx or Xx. Xxxxxxx Xxxxxxxxxx (the "Senior Supervisory Personnel") for, or a plea of guilty or no contest to, fraud or a felony each solely in connection with the services to be provided under the MSA shall automatically constitute Cause without having to be submitted to arbitration pursuant to the above.

	Terms of the MSA which survive termination to be agreed.
Liability	TMS shall be under no liability whatsoever to the Group for any loss, damage, delay or expense of whatsoever nature, whether direct or indirect, and howsoever arising in the course of performance of the services under the MSA unless same is proved to have resulted from the willful default of TMS or its employees or agents, or sub-contractors employed by TMS, in which case TMS' liability for each incident or series of incidents giving rise to a claim or claims shall never exceed a total of (a) for the first year of the MSA, $15 5 million, and (b) thereafter, the aggregate fees paid under the MSA during the immediately preceding twelve-month period; provided, however, that notwithstanding the foregoing, there shall be no limitation on liability in the case of a loss, damage, delay or expense resulting from fraud or theft of Senior Supervisory Personnel.

The Parties to the MSA Agreement will submit any dispute under or arising under the MSA to arbitration in London, England, in accordance with LMAA rules.

Rulings of the arbitrators will be by majority vote of the three arbitrators.
MEP	Parent shall grant to TMS post-Effective Date ordinary shares of Parent in the amount provided in the Restructuring Agreement. Such ordinary shares will vest 25% on each anniversary of such grant.
	If there is a termination of the MSA for Cause that TMS objects to, TMS will forfeit all of its unvested shares, provided that (a) such forfeiture will only occur upon either (x) in the case of a Cause event under subsections (i) or (iii) of the definition of Cause herein, (A) if no

Sch. 8-6

Objection Notice is timely delivered, upon the date of termination of the MSA, and (B) otherwise, upon the determination by the arbitrator that Cause exists; or (y) a conviction for, or a plea of guilty or no contest to, fraud or a felony each solely in connection with the services to be provided under the MSA by either of the Senior Supervisory Personnel and (b) the number of unvested shares subject to such forfeiture shall be calculated as of the date of termination.
