Except as set forth in Section 3.19 of the Disclosure Schedule, no officer, director or shareholder of the Company (other than a member of the WLR Group), or any Affiliate or family member thereof, is a party to any contract, commitment or transaction with any other member of the Company Group or has any interest in any property used or held for use by the Company Group.

The Company and the Board have taken all necessary action, if any, in order to render inapplicable to the transactions contemplated by this Agreement any control share acquisition, interested stockholder, business combination, stockholder rights plan or similar arrangement relating to accumulations of beneficial ownership of Common Shares or other similar anti-takeover provision under the Company’s Constituent Documents or the Laws of the jurisdiction of its incorporation or otherwise which is or would reasonably be expected to become applicable to any Investor as a result of the transactions contemplated by this Agreement.

3.22. Vessels. (a) Either the Company or any of its Subsidiaries, as applicable, is, or will be as of the consummation of the APMM Transaction, the sole owner of each vessel described on Section 3.22 of the Disclosure Schedule (each, a “Company Vessel” and, collectively, the “Company Vessels”) and has, or will have as of the consummation of the APMM Transaction, good title to the Company Vessels.

(b) Section 3.22 of the Disclosure Schedule sets forth a description of each Company Vessel, including its name, capacity (cbm), year built, its classification society, the flag under which such Company Vessel is registered and whether such Company Vessel is currently operating in the spot or time charter market. Each Company Vessel (i) is duly registered as a vessel under the Laws of the jurisdiction set forth opposite its name on Section 3.22 of the Disclosure Schedule, (ii) is seaworthy and in good operating condition, (iii) has all national and international operating and trading certificates and endorsements, each valid and unextended, that are required for the operation of such Company Vessel in the trades and geographic areas in which it is operated, and (iv) has been classed by a classification society that is a member of the International Association of Classification Societies, and is fully in class with no outstanding material recommendations or notations. No event has occurred and no condition exists that would cause any Company Vessel’s class to be suspended or withdrawn, and all events and conditions that are required to be reported as to class have been disclosed and reported to such Company Vessel’s classification society.

(c) The Company Vessels are (i) free of damage affecting their class, (ii) have all their classification trading and statutory certificates and national certificates, as well as other certificates, plans and technical documentation, and (iii) supplied with spare parts at levels consistent with operational needs and such spare parts are in the aggregate usable in the ordinary course of business.

The Framework Agreement and the Nordea Credit Facility are (a) legal, valid and binding obligations of the Company Group and each of the other parties thereto and (b) enforceable in accordance with their respective terms against the Company Group and each of the other parties thereto, subject, as to clause (b), to the Enforceability Exceptions. No event has occurred which, with or without notice, lapse of time or both, would or would reasonably be expected to constitute a default or breach on the part of any parties thereto under the Framework Agreement or the Nordea Credit Facility. The Company does not have any reason to believe that any of the conditions to any Utilisation (as defined in the Nordea Credit Facility) will not be satisfied or that any Utilisation will not be made available to the Company as necessary to permit it to complete the APMM Transaction on the terms set forth in the Framework Agreement. The Company will be able to satisfy all the conditions to each Utilisation that are within its control on each Utilisation Date (as defined in the Nordea Credit Facility).

(b) Exhibit B accurately reflects the purchase price to be paid by the Company Group in respect of each APMM Vessel pursuant to the Framework Agreement. As of the date of this Agreement, the Company has not received any notice from Sellers under the Framework Agreement to the effect that, or otherwise obtained Knowledge that, the delivery of the Maersk Global, Maersk Gusto or Maersk Genesis vessels identified on Exhibit B is reasonably likely to be delayed by more than five Business Days after its respective Anticipated Delivery Date.

(c) The Company has completed the purchase of the Maersk Galaxy with the purchase price therefor paid from the proceeds of the issuance of the 2012 Bonds, and such vessel has been delivered to the Company.

5.3. Performance. Except as otherwise required pursuant to an Order, prior to the Closing, each of the parties will use commercially reasonable efforts to satisfy or cause to be satisfied with respect to itself all of the conditions to the obligations of the other parties set forth in Sections 6.2, 6.3 and 6.4.

(i) the breach of or failure of a representation or warranty made by the Company in this Agreement to be true and correct as of the date hereof and/or as of the Closing Date (except for such representations and warranties that only speak as to a particular time, in which case only at and as of such time) in all material respects; and

(ii) any breach of or failure to perform any covenant, agreement or obligation of the Company in this Agreement in all material respects.

(b) Subject to Sections 7.1 and 7.4, from and after the Closing Date each Investor will, severally and not jointly, indemnify, defend and hold the Company and its directors, officers, employees, stockholders, partners, equityholders, representatives, Affiliates, representatives, successors and permitted assigns harmless from and against any and all Losses, including any further Losses arising from the payment of, or obligation to pay, any indemnity claim relating to such Losses, based upon, or resulting from:

(i) the breach of or failure of a representation or warranty made by such Investor with respect to itself but not with respect to any other Investor in this Agreement to be true and correct as of the date hereof and/or as of the Closing (except for such representations and warranties that only speak as to a particular time, in which case only at and as of such time) in all material respects; and

(ii) any breach of or failure to perform any covenant, agreement or obligation of such Investor with respect to itself or, with respect to any Investor in the WLR Group, with respect to WLR, but not with respect to any other Investor in this Agreement, in all material respects.

7.3. Indemnification Procedures. (a) A claim for indemnification for any matter not involving a third party claim may be asserted by written notice to the party from whom indemnification is sought.

(b) In the event that any legal proceedings are instituted or that any claim or demand is asserted by any third party in respect of which payment may be sought under Section 7.2 (taking into account the limitations set forth in Section 7.4 and Section 7.5) (an “Indemnification Claim”), the Indemnified Party will promptly cause written notice of the assertion of any Indemnification Claim of which it has knowledge which is covered by this indemnity to be forwarded to the Indemnifying Party and will provide a summary of the nature and basis of the legal proceeding, claim or demand and the basis for Indemnification Claim. The failure of the Indemnified Party to give reasonably prompt notice of any Indemnification Claim will not release, waive or

otherwise affect the Indemnifying Party’s obligations with respect thereto except to the extent that the Indemnifying Party is prejudiced as a result of such failure. The Indemnifying Party will have 30 days from receipt of such notice to give notice to the Indemnified Party to assume the defense thereof. If notice to the effect set forth in the immediately preceding sentence is given by the Indemnifying Party, the Indemnifying Party will have the right, at its sole expense, to be represented by counsel of its choice, which must be reasonably satisfactory to the Indemnified Party, and to assume the defense of any such Indemnification Claim which relates to any Losses indemnified against hereunder; provided, however, that if the Indemnifying Party elects to assume control of such defense, it will agree in writing to be responsible for all Losses relating to such Indemnification Claim; and provided, further, however, that the (i) Indemnifying Party will not be entitled to assume control of such defense if (A) the claim for indemnification relates to or arises in connection with any criminal proceeding, action, indictment, allegation or investigation or (B) the claim seeks an injunction or equitable relief against the Indemnified Party, and (ii) Indemnified Party will be entitled to assume control of such defense if the Indemnifying Party fails to diligently defend such claim or if the Indemnifying Party fails to provide notice that it will assume the defense within the time provided herein. If the Indemnifying Party has assumed such defense, the Indemnified Party will be entitled to participate in the defense of such claim and to employ counsel of its choice for such purpose at its own expense. The Parties agree to cooperate reasonably with each other in connection with the defense, negotiation or settlement of any such Indemnification Claim; provided, however, that nothing herein will prevent the Indemnifying Party or the Indemnified Party from separately defending an Indemnification Claim at such party’s own cost and expense to the extent that (x) the Indemnification Claim would reasonably be expected to adversely affect the Indemnified Party or its Affiliates in any material respect other than with respect to the payment of monetary damages in an amount that does not exceed the Cap, (y) a material conflict of interest arises between the interests of the Indemnifying Party and the Indemnified Party in connection with such defense, or there are specific material defenses available to one party that are different from, or in addition to, those available to the other party and that could reasonably be expected to be materially adverse to the other party, or (z) the Indemnification Claim involves monetary damages in an amount in excess of the Cap. Notwithstanding anything in this Section 7.3 to the contrary, neither the Indemnifying Party nor the Indemnified Party will, without the written consent of the other, settle or compromise any Indemnification Claim or permit a default or consent to entry of any judgment unless (I) the claimant or claimants and such party provide to such other party an unqualified release from all liability in respect of the Indemnification Claim or (II) such Indemnification Claim only involves payment of monetary damages not in excess of the Cap. If the Indemnifying Party makes any payment on any Indemnification Claim, the Indemnifying Party will be subrogated, to the extent of such payment, to all rights and remedies of the Indemnified Party to any insurance benefits or other claims of the Indemnified Party with respect to such Indemnification Claim.

7.4. Limitations on Indemnification. (a) Notwithstanding any other provision of this Agreement to the contrary, (i) the Indemnifying Party will not be liable under this Article 7 for any Losses to the extent that the Indemnified Parties have otherwise been fully compensated for such Losses pursuant to this Article 7 so as to avoid “double counting” of the same Losses and (ii) each of the parties hereto will use their commercially reasonable efforts to mitigate all Losses relating to an Indemnification Claim contemplated by Section 7.3(b).

(b) From and after the Closing Date, except with respect to claims for fraud or willful misconduct, the sole and exclusive remedy for any and all Losses arising out or relating to any breach, or alleged breach, of any representation or warranty or any covenant or agreement in this Agreement, will be the indemnification provisions set forth in this Article 7, and the parties hereto each hereby waive to the maximum extent permitted by applicable Law any other remedy to which they or any other Person entitled to indemnification hereunder may have at Law or in equity with respect thereto; provided, however, that nothing in this Section 7.4(b) will prevent any party from exercising its rights pursuant to Section 8.5 in lieu of the indemnification provisions set forth in this Article 7.

(c) Notwithstanding any other provision hereof, in no event will the aggregate amount of Losses for which an Indemnifying Party is obligated to indemnify the Indemnified Parties pursuant to Section 7.2(a)(i) or Section 7.2(b)(i) exceed the Purchase Price (the “Cap”); provided, however, that the Cap will not limit the indemnification of the Indemnified Parties with respect to any Losses resulting from or relating to breaches of any Fundamental Reps (other than breaches of Section 3.9) or any Losses to the extent resulting from fraud on the part of the Indemnifying Party.

7.5. Additional Limitations. Notwithstanding anything to the contrary contained herein, no party hereto will be liable to or otherwise responsible to any Indemnified Party for any punitive damages (other than punitive damages awarded to a third party pursuant to a third party Indemnification Claim) or any damages based on the theory that such party could have used the amounts funded herein in respect of the Purchase Price for other investments.

8.1. Expenses. Except as expressly provided in Section 8.4, each of the parties will pay its own legal, accounting and other miscellaneous expenses incident to this Agreement, except that the Company will pay on behalf of or reimburse the WLR Group for all actual and reasonable fees and expenses, incurred by or on behalf of the WLR Investors in connection with the negotiation, preparation, execution and delivery of this Agreement, the WLR Commitment Letter, the Amended and Restated Investor Rights Agreement and any and all documentation or other acts relating to the consummation of the transactions contemplated hereby, including but not limited to the actual and reasonable fees of counsel, accountants and/or consultants to the WLR Investors billed at standard hourly rates and disbursements (the “Investor Costs”). Such payments will be made by the Company (i) by deduction from the amounts specified on Exhibit C of the amount of applicable Investor Costs either paid by or on behalf of the WLR Investors or as to which the WLR Investors have received invoices prior to the Closing and (ii) promptly and in any event within ten Business Days after request therefor (accompanied by reasonable substantiating documentation) is made, for all Investor Costs not reimbursed pursuant to clause (ii) above.

8.2. Notices. All notices, requests, demands and other communications made under or by reason of the provisions of this Agreement must be in writing and be given by hand delivery, email, facsimile or next Business Day courier to the affected party at the addresses and facsimile numbers set forth below or at such other addresses or facsimile numbers as such party may have provided to the other parties in accordance herewith. Such notices will be deemed given at the time personally delivered (if delivered by hand with receipt acknowledged), upon issuance by the transmitting machine of confirmation that the number of pages constituting the notice has been transmitted without error and confirmed telephonically (if sent by email or facsimile), and the first Business Day after timely delivery to the courier (if sent by next-Business Day courier specifying next-Business Day delivery).

8.3. Interpretation. This Agreement has been freely and fairly negotiated among the parties. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties and no presumption or burden of proof will arise favoring or disfavoring any party because of the authorship of any provision of this Agreement. When a reference is made in this Agreement to an Article, Section or Exhibit, such reference will be to an Article, Section or Exhibit of this Agreement unless otherwise indicated. The headings contained in this Agreement are for reference purposes only and will not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they will be deemed to be followed by the words “without limitation.” “$” refers to U.S. dollars. Words used in the singular form in this Agreement will be deemed to include the plural, and vice versa, as the context may require. If the date upon or by which any party hereto is required to perform any covenant or obligation hereunder falls on a day that is not a Business Day, then such

date of performance will be automatically extended to the next Business Day thereafter. The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement will refer to this Agreement as a whole and not to any particular provision of this Agreement. Unless the context otherwise requires, (i) “or” is disjunctive but not necessarily exclusive, (ii) the use in this Agreement of a pronoun in reference to a party hereto includes the masculine, feminine or neuter, as the context may require, and (iii) unless otherwise defined herein, terms used herein which are defined in GAAP have the meanings ascribed to them therein. All Exhibits hereto will be deemed part of this Agreement and included in any reference to this Agreement. Any agreement, instrument or Law defined or referred to herein means such agreement, instrument or Law as from time to time amended, modified or supplemented (and, in the case of any Law, the rules and regulations promulgated thereunder), including (in the case of agreements or instruments) by waiver or consent and (in the case of Laws) by succession of comparable successor Laws.

8.4. Governing Law. This Agreement, any claims, causes of actions or disputes (whether in contract or tort) based upon, arising out of or relating to this Agreement or the negotiation, execution or performance of this Agreement will be governed by and construed in accordance with the Laws applicable to contracts made and to be performed entirely in the State of New York, United States of America, without regard to any applicable conflict of Laws principles. The parties hereto agree that any action seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Agreement will only be brought in any United States District Court located in New York County, New York so long as such court has subject matter jurisdiction over such action, or alternatively in any New York State Court located in New York County, New York if the aforesaid United States District Courts do not have subject matter jurisdiction, and that any cause of action arising out of this Agreement will be deemed to have arisen from a transaction of business in the State of New York, and each of the parties hereby irrevocably consents to the jurisdiction of such court (and of the appropriate appellate courts therefrom) in any such action and irrevocably waives any objection that it may now or hereafter have to the laying of the venue of any such action in any such court or that any such action which is brought in such court has been brought in an inconvenient forum. Process in any such action may be served on any party anywhere in the world, whether within or without the jurisdiction of such court. Without limiting the foregoing, each party agrees that service of process on such party as provided in Section 8.2 will be deemed effective service of process on such party. In the event of litigation relating to this Agreement, the non-prevailing party will be liable and pay to the prevailing party the reasonable costs and expenses (including attorney’s fees) incurred by the prevailing party in connection with such litigation, including any appeal therefrom.

8.5. Specific Performance. The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, that monetary damages may be inadequate and that a party may have no adequate remedy at Law. Notwithstanding Section 8.4, the parties accordingly agree that the parties will be entitled to an injunction or injunctions to prevent breaches of this Agreement and to

enforce specifically the terms and provisions of this Agreement in action instituted in a United States District Court located in New York County, New York, this being in addition to any other remedy to which such party is entitled at Law or in equity. In the event that a party seeks in equity to enforce the provisions of this Agreement, no party will allege, and each party hereby waives the defense or counterclaim that, there is an adequate remedy at Law.

8.6. Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement may be assigned or delegated by any of the parties without the prior written consent of the other parties. Notwithstanding the foregoing, each Investor will have the right to assign and delegate all of its rights, interests and obligations under this Agreement, including the right to enforce all of the terms of this Agreement, to an Affiliate of such Investor, including any Affiliated fund, and provided further that, in each case, (a) such assignee expressly agrees to be bound by the terms of this Agreement and the Amended and Restated Investor Rights Agreement, if applicable, and (b) no such assignment will relieve such Investor from its obligations hereunder. Subject to the two preceding sentences, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective assigns.

8.7. Amendment. This Agreement may not be amended or modified by the parties except (a) by an instrument in writing signed by the Company, WLR (on behalf of the WLR Group) and the Other Investors or (b) by a waiver in accordance with Section 8.8.

8.8. Extension; Waiver. Any waiver hereunder will be valid only if set forth in a written instrument signed by the party or parties entitled to waive the provision being so waived. The failure or delay of any of the parties to assert any of its rights or remedies under this Agreement will not constitute a waiver of such rights nor will it preclude any other or further exercise of the same or of any other right or remedy.

8.9. No Third-Party Beneficiaries. This Agreement is for the sole benefit of the parties and their permitted assigns and nothing herein expressed or implied will give or be construed to give any Person, other than the parties and such assigns, any legal or equitable rights hereunder.

8.10. Entire Agreement. This Agreement (including the exhibits hereto) constitutes the entire agreement among the parties hereto with respect to the subject matter hereof and supersedes all prior agreements, understandings, representations and undertakings, both written and oral, among the parties with respect to the subject matter hereof and thereof. Notwithstanding the foregoing, this Agreement will not supersede or affect the terms or enforceability of Sections 4 and 5 of the WLR Commitment Letter, which will continue in full force and effect.

8.11. Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy in any jurisdiction, all other terms and provisions of this Agreement will nevertheless remain in full force and effect so long as the economic or legal substance of the transactions and the intention of the parties with respect to the transactions contemplated hereby is not affected in any manner materially adverse to any of the parties. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties will negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

8.12. Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed an original, but all of which will constitute one and the same agreement. This Agreement may be executed by any party hereto by means of a facsimile, email or PDF transmission of an originally executed counterpart, the delivery of which facsimile, email or PDF transmission will have the same force and effect, except as specified in any document executed and delivered pursuant to the immediately preceding sentence, as the delivery of the originally executed counterpart.

8.13. WLR as Representative Party. Each Investor in the WLR Group irrevocably appoints WLR as its representative to take any action contemplated hereunder to be taken by it, including the execution and delivery of any consent or waiver hereunder or amendment hereto. WLR will have no liability or obligation to the Company for any act or failure to act; provided, however, that nothing herein will relieve any Investor in the WLR Group from any liability under this Agreement for any breach by WLR of any of its obligations under this Agreement.

8.14. No Relationship Among Certain Investors. Each member of the WLR Group, each of the Other Investors and the Company acknowledge and agree that (i) this Agreement is being jointly negotiated and entered into by the members of the WLR Group and the Other Investors solely for convenience and will not create any relationship or obligations among such Persons except as otherwise expressly set forth herein, (ii) the Other Investors will have no right to act as representatives of any member of the WLR Group or take any action contemplated hereunder to be taken by a member of the WLR Group on behalf of such Person and vice versa, and (iii) no breach by an Other Investor of its obligations hereunder will create any Liability for any member of the WLR Group and vice versa.

8.15. Certain Consents and Waivers. The parties hereto acknowledge the extent of the prior and existing representations by counsel of the parties hereto and of the parties to this Agreement and the Amended and Restated Investor Rights Agreement and have affirmatively consented to Jones Day’s representation of the WLR Group and Morgan, Lewis & Bockius LLP’s representation of the Company, in both cases in connection with this Agreement and the Amended and Restated Investor Rights Agreement, the transactions contemplated hereby and thereby, and any related or unrelated transactional or litigation matters now existing or arising in the future. The parties waive any objection to such representations, any conflict of interest or other basis for precluding, challenging or otherwise disqualifying the above-referenced firms

from such representations based on any prior or existing representation by either such firm, and agree that no such objection, conflict of interest or other basis for precluding, challenging or otherwise disqualifying the above-referenced firms from representing their respective clients will be asserted by either party if litigation among the parties hereto, or any of them, proceeds or develops, whether or not the transactions contemplated hereby are or have been consummated. Each party has had the opportunity to consult with counsel concerning this waiver, and confirms that its consent is voluntary, fully informed and to be relied upon by the other party hereto and the above-referenced firms.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first written above.
