("Parent"), Drillships Financing Holding Inc., Drillships Ocean Ventures Inc., Drill Rigs Holdings Inc. and the Supporting Creditors (the "RSA") is made by and among Parent (on behalf of itself and each of the Scheme Companies) and the Supporting Creditors listed on the signature pages hereto, which constitute the Majority Supporting Lenders. Capitalized terms used but not defined herein have the meanings set forth in the RSA or the applicable amendments thereto.

RECITALS

WHEREAS, the Parent (on behalf of itself and each of the Scheme Companies) and the Majority Supporting Lenders desire to amend the RSA to reflect an agreement with certain holders of DRH Scheme Claims who hold a blocking position in the DRH Scheme and who had previously advised that they intended to reject the DRH Scheme (the "DRH Group");

WHEREAS, the implementation of the agreement reached with the DRH Group involves the reallocation of certain of the DFH Scheme Consideration, the DOV Scheme Consideration, and the MEP consideration to DRH for distributions to its creditors; and

WHEREAS, subject to the approval of this Amendment by the Parent (on behalf of itself and each of the Scheme Companies) and the Majority Supporting Lenders, each member of the DRH Group agrees to accede to and become bound by the RSA as amended herein.

NOW, THEREFORE, the parties hereto agree as follows:

1. AMENDMENT

The Scheme Companies and the Majority Supporting Lenders have agreed to amend the RSA as follows:

(a) In Clause 9 (THE RESTRUCTURING EFFECTIVE DATE), by (i) adding the words "subject to any applicable fee cap" at the beginning of paragraph (g), (ii) adding the words ", the DRH Group," after "the Group" and before the words "and to the Ad Hoc Committee" in paragraph (g), (iii) deleting the word "and" at the end of paragraph (g), (iv) by deleting the "." at the end of paragraph (h) and replacing it with "; and", and (v) by adding the following new paragraph (i):

(i) the documents constituting the Preserved Claims Trust shall have been executed and held in escrow until the Restructuring Effective Date in accordance with the Parent Scheme.

(b) In Clause 11 (RESTRUCTURING EFFECTIVE DATE WAIVER AND RELEASE) by adding the words "to the Preserved Parent Claims or" before the words "to any claim arising out of" in the proviso.

(c) by deleting the title to Clause 12 and replacing it with the following: "EARLY CONSENT/PUT OPTION";

(d) In Clause 12.2 (DRH EARLY CONSENT FEE), by deleting the text thereof in its entirety and replacing it with the following:

"(a) Subject to paragraph (b) below, each holder of DRH Scheme Claims that has acceded to this Agreement by the DRH Early Consent Deadline will receive its pro rata portion of the DRH Early Consent Fee with respect to such Claims (calculated with respect to all holders of DRH Scheme Claims who have acceded to this Agreement by the DRH Early Consent Deadline) on, and subject to the occurrence of, the Restructuring Effective Date of the DRH Scheme.

(b) Any holder of a DRH Scheme Claim that has acceded to this Agreement before the DRH Early Consent Deadline that (i) fails to vote in favor of the relevant Schemes with respect to any of its Claims or (ii) has committed a Material Breach of its obligations under this Agreement that results in the Parent terminating this Agreement with respect to such breaching holder shall, without limiting any other remedies that a Party may have against it under this Agreement, forfeit its entitlement to any DRH Early Consent Fee and any such DRH Early Consent Fee that it would otherwise have received shall be distributed, on a pro rata basis, to other holders of DRH Scheme Claims that remain entitled to receive the DRH Early Consent Fee."

(e) In Clause 12.3(b), by deleting the term "DRH Early Consent Date" each time it appears and replacing the term with "DRH Early Consent Deadline", and by adding the following parenthetical after the words "Record Date":

"(provided, however, that the DRH Put Underwriters shall be deemed to have complied with Clause 3.4(e) and 12.1(c) with respect to their obligations as of May 15, 2017 under this Agreement subject to their compliance with Clause 13 (Accession) within one Business Day of the effective date of this Amendment)".

(f) by adding a new Clause 12.3.1 as follows:

"12.3.1 DRH Put Option/Backstop Rights and Backstop DRH Scheme Claims

(a) Any holder of a DRH Scheme Claim, regardless of whether such holder has acceded to this Agreement, may elect to exercise the DRH Put Option.

(b) If the DRH Scheme is sanctioned and becomes effective, each of the DRH Put Underwriters shall receive its pro rata share (calculated based on all DRH Scheme Claims held by each of the DRH Put Underwriters) of the DRH Put Underwriters Fee on the Restructuring Effective Date;

2

(c) The obligation of each DRH Put Underwriter to underwrite the DRH Put Option will be several and not joint and otherwise as specified in the DRH Put Underwriter Commitment Letter; provided, that in the event that a DRH Put Underwriter fails to fund its pro rata share of the DRH Put Price, the other non-defaulting DRH Put Underwriters may elect to, but are not obligated to, fund such defaulting DRH Put Underwriter's pro rata share of the DRH Put Price and receive such defaulting DRH Put Underwriter's pro rata share of the DRH Put Underwriters Fee (in accordance with Clause 12.3.1(b)). The obligation to fund the DRH Put Option and the corresponding right to receive a pro rata share of the DRH Put Underwriters Fee as described in Clause 12.3.1(b) will be fixed as of the date of this Amendment on a pro rata basis (calculated based on all DRH Scheme Claims held by each of the DRH Put Underwriters on such date) (such DRH Scheme Claims, the "Backstop Rights"). After the effective date of this Amendment, a holder of Backstop Rights may only transfer such Backstop Rights to a party other than a DRH Put Underwriter that is party to this Amendment (or any of its affiliates) with the consent of the Parent (which consent will not be unreasonably withheld). For the avoidance of doubt, the DRH Scheme Claims held by the DRH Put Underwriters shall, subject to the provisions of Clause 14 (Transfer of Claims), remain freely tradeable (i.e., without the consent of the Company or any other party)."

(g) by adding a new Clause 16.2(f), as follows:

"(f) by the Majority DRH Put Underwriters giving written notice to the Parent to terminate with respect to the DRH Put Underwriters only, if any of the following events occur (it being understood, for the avoidance of doubt, that any such termination on account of the foregoing shall also terminate the obligation of each DRH Put Underwriter to underwrite the DRH Put Option):

(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

3

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);

(iii) if any of the Group Members fails, as determined in good faith by the Majority DRH Put Underwriters, to use commercially reasonable efforts to ensure that any of the steps described in Clause 8.2 (Scheme Implementation Steps) are satisfied;

(iv) if the Parent Scheme Meeting, DFH Scheme Meeting, and DOV Scheme Meeting have been held, and the Requisite Scheme Majorities have not voted in favor of any of the Parent Scheme, the DFH Scheme, or the DOV Scheme, respectively;

(v) if the Parent or any Group Member is or becomes a Sanctions Target;

(vi) 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 DRH Put Underwriters, has failed to remedy such a breach by the earlier of (a) within 14 days of the receipt of written notice from the Majority DRH Put Underwriters, and (b) the Business Day immediately preceding the Restructuring Effective Date;

(vii) 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;

4

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

(ix) the Parent is in breach of its obligation under any fee arrangement to pay any professional fees, costs and expenses incurred by the DRH Put Underwriters, 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."

(h) In Clause 19.2 by (i) deleting the word "or" at the end of paragraph (e), (ii) by deleting the "." at the end of paragraph (f) and replacing it with "; and", (iii) by relabeling existing paragraph "(f)" as paragraph "(g)" and (iii) by adding the following new paragraph (f):

"for any notice to be provided to the DRH Put Underwriters, to Edward O. Sassower, P.C. and Brian Schartz of Kirkland & Ellis LLP (address: 601 Lexington, New York, NY 10033, email: esassower@kirkland.com, bschartz@kirkland.com) and to Mark Goodman and Hamid Khanbhai of Campbells (address: Floor 4, Willow House, Cricket Square, Grand Cayman KY1-9010, Cayman Islands, email: MGoodman@campbellslegal.com, HKhanbhai@campbellslegal.com)."

(i) In Clause 23.1 by deleting the "." at the end of the clause and inserting the following: "and provided, further, that no amendment or waiver may be made without the consent of the Majority DRH Put Underwriters that (i) materially adversely affects the rights and entitlements of the holders of the DRH Scheme Claims in a disproportionate manner to the rights and entitlement of the Supporting Creditors generally, or (ii) provides materially different treatment for the holders of the DRH Scheme Claims than provided in this Amendment (it being understood that any change to the definition of DRH Scheme Consideration or DRH Put Underwriters Fee shall constitute materially different treatment for purposes of this Clause 23)."

(j) by deleting clause (b) of the definition of "DRH Scheme Consideration" in Schedule 1 (Definitions) and replacing it with the following:

"either (i) the DRH Scheme Shares, or (ii) the DRH Put Consideration by electing the DRH Put Option; provided, that a holder of the DRH Scheme Claims (other than the DRH Put Underwriters) must properly elect the DRH Put Option on its DRH Scheme ballot on the date of the Scheme Meetings."
