Reference is made to the Facility Agreement and to a letter from you dated 14 March 2016, whereby you have requested that the Facility Agreement be amended on the terms set out therein (the “Amendment Request”).

Capitalised terms used in this letter shall, unless otherwise stated in this letter (including in schedule 3 (Definitions) to this letter), have the same meaning as assigned to them in the Facility Agreement.

1. CONSENT

We, the undersigned, acting as Agent with the consent and authorisation of the Majority Lenders, hereby consent to Request 1B, subject to the terms and conditions set out herein, such consent to become effective on the Effective Date.

2. AMENDMENTS TO THE FACILITY AGREEMENT

(a) On the Effective Date, the amendments to the Facility Agreement set out in schedule 1 (Amendments to the Facility Agreement) to this letter will be made to the Facility Agreement to reflect the consent of the Agent (on behalf of the Majority Lenders) to Request 1B in accordance with paragraph 1 above.

(b) For the avoidance of doubt, clause 8.4 (Minimum Market Value) of the Facility Agreement will not apply whilst the minimum Market Value covenant in clause 24.1 (Minimum Market Value) of the Facility Agreement is suspended.

(c) The amendments to the Facility Agreement in schedule 1 (Amendments to the Facility Agreement) to this letter (other than paragraphs 2, 3, 5, 6, 10, 11 and 12 of schedule 1) and the Agent’s confirmation in paragraph 5 below shall only be effective until the Deferral Date, on which date such amendments will be reversed, such confirmation shall cease to have effect and the rights and remedies available to the Lenders prior to the making of such amendments and such confirmation shall be reinstated in full.

3. CONDITIONS PRECEDENT

The Borrower and the Parent shall deliver, or procure the delivery, to the Agent, substantially in a form and substance which has been agreed with the Agent in writing on or prior to the date of this letter or otherwise in a form and substance satisfactory to the Agent, all of the documents and evidence listed in schedule 2 (Conditions Precedent) to this letter. The Agent shall notify the Borrower, the Parent and the Lenders promptly after such conditions having been satisfied.

4. PARENT’S UNDERTAKINGS

The below undertakings (other than the undertakings under paragraph (a) below) are agreed on the basis that they are intended only to apply on a temporary basis during the Negotiation Period and will need to be revisited and put on a more permanent footing as part of the amendment and extension requests issued in connection with implementing the Parent’s proposals for the recapitalisation of the Group. The below undertakings shall apply in addition to and shall not waive or release any existing obligation on any Obligor under the Facility Agreement.

The Parent undertakes to the Agent on behalf of the Finance Parties, which undertakings shall be considered given by the Parent’s acceptance of the terms set out in this letter, that (save as the Agent (acting on the instructions of the Majority Lenders) may otherwise agree in writing):

(a) it shall:

(i) by no later than 16 May 2016 provide to the Co-Com and Co-Com Advisors an indicative legal analysis prepared by the Parent and its advisors for contingency planning purposes including without limitation in respect of (1) the potential use of an English and/or local law scheme of arrangement to implement a non-consensual restructuring, (2) the potential use of a US Chapter 11 plan of reorganisation to implement a non-consensual restructuring, and (3) the potential legal impact on the Parent of a change in governing law, in each case with respect to the Group Facility Agreements and any other instrument relating to Financial Indebtedness of any member of the Group;

(ii) by no later than 16 May 2016, present to the Co-Com and the Co-Com Advisors its proposals for the recapitalisation of the Group broadly consistent with the proposals presented by the Parent to the Co-Com at the meeting between the Parent and the Co-Com on 10 March 2016 and showing sustainability of funding through 2020, accompanied by an updated financial model with assumptions based on updated feedback from Fearnleys and in respect of cost items assumptions based on any guidance provided by the Parent to the capital markets;

(iii) by no later than 30 June 2016, present to the lenders and each of the facility agents under the Group Facility Agreements for approval amendment and extension requests setting out its proposals for the recapitalisation of the Group showing sustainability of funding through 2020 (taking into account input from the Co-Com and the Co-Com Advisors);

(iv) at any time after the presentation of amendment and extension requests for approval pursuant to paragraph (iii) above and by no later than 1 September 2016, if requested by the Co-Com on not less than 10 calendar days’ prior notice, on a single occasion, host a meeting for the Co-Com (and, if requested by the Co-Com, all lenders under the Group Facility Agreements) at which the Parent will present an update on the status of its plans for and developments in relation to the restructuring of the bonds and notes issued by the Parent and other members of the Group including without limitation principal and coupon amounts payable thereunder and an update on its proposal for the recapitalisation of the Group; and

(v) use reasonable endeavours to ensure that by no later than 31 December 2016 and otherwise to ensure that by no later than 30 April 2017, the amendments contemplated in the amendment and extension requests presented for approval pursuant to paragraph (iii) above have become effective and its proposed recapitalisation of the Group has been implemented on terms satisfactory to the Majority Lenders,

provided that:

(A) each of the dates given in the Milestones above (other than the Milestones set out in paragraphs (iv) and (v) above for which no grace period applies) is subject to a grace period of 15 calendar days, or 30 calendar days in respect of the Milestone set out in paragraph (iii) above; and

(B) each Milestone, on a single occasion only, may be varied at the written request of the Parent with the consent of the Agent in its sole discretion if the request relates to a further delay of 15 calendar days beyond either the due date or (if applicable) the end of the grace period referred to in (A) above. Other

than to the extent that the Majority Lenders notify the Agent in writing to the contrary before the Agent gives such a consent, the Majority Lenders are by their approval of this letter deemed to have authorised (but not required) the Agent to give that consent. The Agent confirms that it has considered whether it is able to consent to such a delay without requiring instructions from the Majority Lenders in addition to the terms of this letter and has satisfied itself that it is able to do so. The Agent shall not be liable for any damages, costs or losses whatsoever as a result of giving any such consent;

(b) it shall not (and shall ensure that no other member of the Group shall) during the Negotiation Period incur or allow to remain outstanding any Financial Indebtedness other than Permitted Financial Indebtedness;

(c) during the Negotiation Period, it shall not, irrespective of any term of the Finance Documents to the contrary:

(i) make any dividend payments or other distributions in respect of its share capital to its shareholders;

(ii) enter into new total return swaps (for the avoidance of doubt, excluding roll-over or unwinding, in whole or in part, of existing total return swaps (which roll-over or unwinding will include the purchase of shares and corresponding reduction of any such existing total return swap)) or enter into similar transactions with similar effect; or

(iii) buy back or redeem any shares in its capital,

in each case, other than to the extent any of the same occurs solely as part of the operation in the ordinary course of business of any executive or employee benefit scheme or plan. This undertaking shall, from and including the Effective Date, supersede the equivalent undertaking given by the Parent pursuant to the consent letter from the Agent dated 28 May 2015;

(d) during the Negotiation Period, it shall not (and it shall procure that no other member of the Group shall) prepay, repay, purchase or otherwise acquire, in each case voluntarily, any loans under any of the Group Facility Agreements (provided that it shall not be prohibited from taking any action with respect to Financial Indebtedness as described in sub-paragraph (iv) of the definition of Permitted Financial Indebtedness);

(e) during the Negotiation Period, it shall not (and it shall procure that no other member of the Group shall) buy back or redeem, in each case voluntarily, any bonds or notes issued by it;

(f) during the Negotiation Period, it shall not (and it shall procure that no other member of the Group shall) voluntarily close out any hedging or derivative transaction entered into with any person who is not a member of the Group except for the voluntary closing out of hedging or derivative transactions (A) where the Group is over-hedged and only the over-hedged position is being closed out or (B) where the same does not crystallise cash outflows for members of the Group during the Negotiation Period other than scheduled payments in the ordinary course under the terms of the restructured hedging or derivative transaction and so that any negative values are baked into the rates agreed as part of the restructuring;

(g) it shall not (and shall ensure that no other member of the Group shall) during the Negotiation Period acquire a company or any shares or a business or undertaking (or, in each case, any interest in any of them) or make any equity injections or contributions in each case except for Permitted Acquisitions;

(h) it shall not (and shall ensure that no other member of the Group shall) during the Negotiation Period enter into a single transaction or a series of transactions (whether related or not) and whether voluntary or involuntary to sell, lease, transfer or otherwise dispose of any asset other than as part of a Permitted Disposal;

(i) it shall not (and shall ensure that no other member of the Group shall) during the Negotiation Period make any payment to any person who is not a member of the Group under any Newbuild Contract, other than any Permitted Newbuild Contract Payments;

(j) it shall not (and shall ensure that no other member of the Group shall) during the Negotiation Period provide, procure, create or permit to subsist any Financial Support other than any Permitted Financial Support;

(k) it shall not (and shall ensure that no other member of the Group shall) during the Negotiation Period:

(i) make any payment pursuant to any Newbuild Contract existing as at the Request Date (other than payments falling within paragraphs (i) to (iii) or (v) of the definition of Permitted Newbuild Contract Payments);

(ii) make any payment to, or for the benefit of, any member of the Minority Holding Group:

(1) under any Existing Financial Support Arrangements provided, procured, created or permitted to subsist to or for the benefit of such member of the Minority Holding Group (including,

without limitation, any Financial Support provided with respect to the financial indebtedness of Xxxxxx Limited and its Subsidiaries from time to time, including under the equity undertaking originally dated 22 December 2015 between the Parent, Xxxxxx Limited and Danske Bank A/S (the “Xxxxxx Equity Undertaking”)); or

(2) in respect of any Financial Support provided, procured, created or permitted to subsist by any member of the Group to or for the benefit of Seamex Ltd. and/or any of Seamex Ltd.’s Subsidiaries; or

(3) in respect of any Financial Support which is provided, procured, created or permitted to subsist in connection with the replacement, refinancing, amendment or extension (or in the case of the Rubi Guarantees, issuance) of bank guarantees and letters of credit with a maturity date falling within the Negotiation Period,

(in each case, for these purposes a “Cash Leakage Payment”) except to the extent that the Parent complies with the following provisions in relation to such Cash Leakage Payment:

(A) in advance of making any such Cash Leakage Payment, the Parent shall, with appropriate legal advice, consider the rights and obligations of the relevant parties with respect to such Cash Leakage Payment to determine whether that Cash Leakage Payment can be legally reduced, postponed, cancelled or otherwise avoided under the terms of the agreement under which the requirement to make that Cash Leakage Payment arises or any related agreements, in each case without materially and adversely affecting the interests of the Group and its financial creditors;

(B) if the Parent determines acting reasonably that the Cash Leakage Payment can be so reduced, postponed, cancelled or otherwise avoided, the Parent shall use its reasonable endeavours to achieve the same;

(C) if the Parent determines acting reasonably that the Cash Leakage Payment cannot be so reduced, postponed, cancelled or otherwise avoided, unless the Parent acting reasonably considers that to do so would not be in the interests of the Group and its financial creditors (because for example, but without limitation, the same risks resulting in additional amounts being claimed from members of the Group) the Parent shall:

(1) use its reasonable endeavours to engage with the relevant payee (or such other party whose consent may be required) to negotiate in good faith a consensual reduction, postponement, cancellation or other avoidance of the Cash Leakage Payment;

(2) promptly provide the Co-Com with details of any proposal made by the Parent to the relevant payee (including, without limitation, with respect to the negotiation in respect of the Xxxxxx Equity Undertaking); and

(3) keep the Co-Com updated as to any material developments with respect to such negotiation and provide the Co-Com with all information as the Co-Com may reasonably request in respect of such negotiations; and

(D) the Parent shall give the Co-Com notice as soon as reasonably practicable on becoming aware that it has become obliged, or is likely to become obliged within a period of 30 calendar days, to make a Cash Leakage Payment, and shall provide the Co-Com with all information as the Co-Com may reasonably request and which the Parent is legally permitted to provide with respect to that Cash Leakage Payment and its circumstances,

provided that, for the avoidance of doubt, nothing in this paragraph (k) shall prohibit the Parent or any other member of the Group from making any Cash Leakage Payment which the Parent is satisfied has become legally due and payable under the terms of the relevant documentation. In particular if the Cash Leakage Payment should become due and payable immediately without notice, neither the Parent nor any member of the Group shall be required to delay the making of the Cash Leakage Payment in order to comply with the terms of sub-paragraphs (A) to (D) above and provided further that the provisions of this paragraph 4(k) shall not apply to the payments of USD 8,000,000 made on 15 April 2016 and USD 8,000,000 scheduled to be made on or about 13 June 2016 under the Parent’s obligations in respect of Sapura Rubi GmbH under the letter of undertaking dated on or about 5 April 2015;

(n) it shall not, and shall procure that no other member of the Group shall, during the Negotiation Period agree to amendments to any of the other Group Facility Agreements or any other instrument relating to Financial Indebtedness of any member of the Group (provided that this provision shall apply only to amendments to any of the Group Facility Agreements, any of the Ship Finance Arrangements or any hedging agreement entered into by any Group member except in respect of amendments to economics) on more favourable terms in any material respect than are provided with respect to the Facility Agreement or, with respect to an extension of tenor, the Maturing Facility Agreements other than any amendments (A) contemplated by the proposals for the recapitalisation of the Group described in paragraphs (a)(ii) and (a)(iii) above, (B) arising from the extension of the Maturing Facility Agreements on the basis agreed with Majority Lenders or any agreement entered into pursuant to the extension approval letters dated on or about the date of this letter or (C) in the case of amendments to economics of any instrument relating to Financial Indebtedness of the Group (other than any of the Group Facility Agreements, any of the Ship Finance Arrangements or any hedging agreement) entered into by any Group member, resulting in an aggregate cost to the Group under this paragraph 4(n) and under paragraph 4(o) below not exceeding USD25,000,000 (or its equivalent in other currencies);

(o) during the Negotiation Period, if any member of the Group agrees to pay higher compensation relative to the Facility Agreement or, with respect to an extension, the Maturing Facility Agreements (whether in the form of margin increases, consent fees or otherwise), save as (A) contemplated by the proposals for the recapitalisation of the Group described in paragraphs (a)(ii) and (a)(iii) above or (B) arising from the extension of the Maturing Facility Agreements on the basis agreed with Majority Lenders) or any agreement entered into pursuant to the extension approval letters relating to the Maturing Facility Agreements dated on or about the date of this letter to secure amendments in any of the other Group Facility Agreements or any other instrument relating to Financial Indebtedness of any member of the Group, it will procure that the terms of the Facility Agreement are amended to reflect this higher compensation and will enter into, or procure that such other member of the Group enters into, such documents as the Agent may reasonably require in order to reflect such higher compensation, save to the extent that the aggregate cost to the Group under this paragraph 4(o) and under paragraph 4(n) above does not exceed USD25,000,000 (or its equivalent in other currencies);
