To the extent there are no additional Underwriters listed on Schedule II other than you, the term Representatives as used herein shall mean you, as Underwriters, and the terms Representatives and Underwriters shall mean either the singular or plural as the context requires.

Any reference herein to the Registration Statement, the Basic Prospectus, any Preliminary Final Prospectus or the Final Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 6 of Form F-3 which were filed under the Exchange Act on or before the Effective Date of the Registration Statement or the issue date of the Basic Prospectus, any Preliminary Final Prospectus or the Final Prospectus, as the case may be; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Basic Prospectus, any Preliminary Final Prospectus or the Final Prospectus shall be deemed to refer to and include the filing of any document under the Exchange Act after the Effective Date of the Registration Statement or the issue date of the Basic Prospectus, any Preliminary

Final Prospectus or the Final Prospectus, as the case may be, deemed to be incorporated therein by reference. Certain terms used herein are defined in Section 20 hereof.

1. Representations and Warranties. The Company represents and warrants to, and agrees with, each Underwriter as set forth below in this Section 1.

(a) The Company meets the requirements for use of Form F-3 under the Act and has prepared and filed with the Commission a shelf registration statement (the file number of which is set forth in Schedule I hereto) on Form F-3, including a related basic prospectus, for registration under the Act of the offering and sale of the Securities, which Registration Statement, including any amendments thereto filed prior to the Applicable Time, has become effective under the Act and no stop order suspending the effectiveness of the Registration Statement has been issued under the Act and no proceedings for that purpose have been instituted or are pending, or to the knowledge of the Company, are threatened. The Company may have filed with the Commission, as part of an amendment to the Registration Statement or pursuant to Rule 424(b), one or more Preliminary Final Prospectuses, each of which has previously been furnished to you and at the time of the filing thereof with the Commission, each such Preliminary Final Prospectus complied in all material respects with the requirements of the Act. The Company will file with the Commission a final prospectus supplement relating to the Securities in accordance with Rule 424(b). As filed, such final prospectus supplement shall contain all information required by the Act and the rules thereunder, and, except to the extent the Representatives shall agree in writing to a modification, shall be in all substantive respects in the form furnished to you prior to the Applicable Time or, to the extent not completed at the Applicable Time, shall contain only such specific additional information and other changes (beyond that contained in the Basic Prospectus and any Preliminary Final Prospectus) as the Company has advised you, prior to the Applicable Time, will be included or made therein. The Registration Statement, at the Applicable Time, meets the requirements set forth in Rule 415(a)(1)(x).

It is understood that the form of prospectus to be used in connection with the offering and sale of the Securities shall have a Canadian “wrap-around” for purposes of distribution to Canadian Persons (the “Canadian OM”).

(b) On each Effective Date, the Registration Statement did, and when the Final Prospectus is first filed (if required) in accordance with Rule 424(b) and on the Closing Date (as defined herein), the Final Prospectus (and any supplement thereto) will, comply in all material respects with the applicable requirements of the Act and the Exchange Act and the respective rules thereunder; on each Effective Date, at the Applicable Time and on the Closing Date, the Registration Statement did not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; and on the date of any filing pursuant to Rule 424(b) and on the Closing Date and any settlement date, the Final Prospectus (together with any supplement thereto) will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances

under which they were made, not misleading; provided, however, that the Company makes no representations or warranties as to the information contained in the Registration Statement or the Final Prospectus (or any supplement thereto) in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion in the Registration Statement or the Final Prospectus (or any supplement thereto), it being understood and agreed that the only such information furnished by or on behalf of any Underwriters consists of the information described as such in Section 8 hereof.

(e) Each Issuer Free Writing Prospectus does not include any information that conflicts with the information contained in the Registration Statement, including any document incorporated therein and any prospectus supplement deemed to be a part thereof that has not been superseded or modified. The foregoing sentence does not apply to statements in any Issuer Free Writing Prospectus based upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8 hereof.

Delivery of and payment for the Securities shall be made at the location, on the date and at the time specified on Schedule I hereto or at such time on such later date not more than three Business Days after the foregoing date as the Representatives shall designate, which date and time may be postponed by agreement between the Representatives and the Company or as provided in Section 9 hereof (such date and time of delivery and payment for the Securities being herein called the “Closing Date”). Delivery of the Securities shall be made to the Representatives for the respective accounts of the several Underwriters against payment by the several Underwriters through the Representatives of the purchase price thereof to or upon the order of the Company by wire transfer payable in same-day funds to an account specified by the Company. Delivery of the Securities shall be made through the facilities of The Depository Trust Company (“DTC”) unless the Representatives shall otherwise instruct.

4. Offering by Underwriters. It is understood that the several Underwriters propose to offer the Securities for sale to the public as set forth in the Final Prospectus and the Canadian OM.

5. Agreements. The Company agrees with the several Underwriters that:

(a) Prior to the termination of the offering of the Securities, the Company will not file any amendment of the Registration Statement or supplement (including the Final Prospectus or any Preliminary Final Prospectus) to the Basic Prospectus or any Rule 462(b) Registration Statement unless the Company has furnished you a copy for your review prior to filing and will not file any such proposed amendment or supplement to which you reasonably object. The Company will cause the Final Prospectus, properly completed, and any supplement thereto to be filed in a form approved by the Representatives with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to the Representatives of such timely filing. The Company will promptly advise the Representatives (i) when the Final Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration Statement shall have been filed with the Commission, (ii) when, prior to termination of the offering of the Securities, any amendment to the Registration Statement shall have been filed or become effective, (iii) of any request by the Commission or its staff for any amendment of the Registration Statement, or for any supplement to the Final Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice that would prevent its use or the institution or threatening of any proceeding for that purpose and (v) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the institution or

threatening of any proceeding for such purpose. The Company will use its commercially reasonable efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or prevention and, upon such issuance, occurrence or prevention, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or prevention, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its commercially reasonable efforts to have such amendment or new registration statement declared effective as soon as practicable.

(b) If there occurs an event or development as a result of which the Disclosure Package would include an untrue statement of a material fact or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, the Company will notify promptly the Representatives so that any use of the Disclosure Package may cease until it is amended or supplemented.

(c) If, at any time when a prospectus relating to the Securities is required to be delivered under the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), any event occurs as a result of which the Final Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, or if it shall be necessary to amend the Registration Statement, file a new registration statement or supplement the Final Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Final Prospectus, the Company promptly will (i) notify the Representatives of such event, (ii) prepare and file with the Commission, subject to the first sentence of paragraph (a) of this Section 5, an amendment or supplement or new registration statement which will correct such statement or omission or effect such compliance, (iii) use its commercially reasonable efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in use of the Final Prospectus and (iv) supply any supplemented Final Prospectus to you in such quantities as you may reasonably request.

(d) As soon as practicable, the Company will make generally available to its security holders and to the Representatives an earnings statement or statements of the Company and its subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158.

(e) The Company will furnish to the Representatives and counsel for the Underwriters signed copies of the Registration Statement (including exhibits thereto) and to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of each Preliminary Final Prospectus,

the Final Prospectus and each Issuer Free Writing Prospectus and any supplement thereto as the Representatives may reasonably request.

(f) The Company will arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions as the Representatives may reasonably designate and will maintain such qualifications in effect so long as reasonably required for the distribution of the Securities; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject.

(g) The Company agrees that, unless it obtains the prior written consent of the Representatives, and each Underwriter, severally and not jointly, agrees with the Company that, unless it has obtained or will obtain, as the case may be, the prior written consent of the Company, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Company with the Commission or retained by the Company under Rule 433; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule III hereto. Any such free writing prospectus consented to by the Representatives or the Company is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement, the Preliminary Final Prospectus or the Final Prospectus or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company will promptly notify the Representatives and will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(h) The Company will not, without the prior written consent of ▇▇▇▇▇▇▇ Lynch, Pierce, ▇▇▇▇▇▇ & ▇▇▇▇▇ Incorporated and Citigroup Global Markets Inc., offer, sell, contract to sell, pledge, or otherwise dispose of, (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Company or any affiliate of the Company or any person in privity with the Company or any affiliate of the Company) directly or indirectly, including the filing (or participation in the filing) of a registration

statement with the Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, any other Existing Preferred Shares or any securities convertible into, or exercisable, or exchangeable for, Existing Preferred Shares; or publicly announce an intention to effect any such transaction, for a period of 45 days after the date of this Agreement, provided, however, that the Company may issue and sell (i) the Securities and (ii) Existing Preferred Shares pursuant to any employee stock option plan, stock ownership plan or dividend reinvestment plan of the Company described in the Disclosure Package and the Final Prospectus (exclusive of any supplement thereto).

(i) The Company will comply in all material respects with all applicable securities and other applicable laws, rules and regulations, including, without limitation, the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act, and will use its commercially reasonable efforts to cause the Company’s directors and officers, in their capacities as such, to comply with such laws, rules and regulations, including, without limitation, the provisions of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act.

(j) The Company will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

(k) The Company will cooperate with the Underwriters in preparing a final term sheet containing a description of the Securities, in a form approved by the Underwriters and attached as Annex A hereto, and will file such term sheet pursuant to Rule 433(d) under the Securities Act within the time required by such rule (such term sheet, the “Final Term Sheet”). Any such Final Term Sheet is an Issuer Free Writing Prospectus for purposes of this Agreement.

(l) The Company agrees to pay the costs, fees and expenses relating to the following matters: (i) the preparation, printing or reproduction and, if applicable, filing with the Commission of the Registration Statement (including financial statements and exhibits thereto), each Preliminary Final Prospectus, each Free Writing Prospectus, the Final Prospectus or Final Prospectus with a Canadian OM and each amendment or supplement to any of them; (ii) the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging) of such copies of the Registration Statement, each Preliminary Final Prospectus, the Final Prospectus or Final Prospectus with a Canadian OM and all amendments or supplements to any of them, as may, in each case, be reasonably requested for use in connection with the offering and sale of the Securities; (iii) the preparation, printing, authentication, issuance and delivery of certificates for the Securities, including any stamp or transfer taxes in connection with the original issuance and sale of the Securities; (iv) the registration of the Securities under the Exchange Act and the listing of the Securities on The New York Stock Exchange; (v) any registration or qualification of the Securities for offer and sale under the securities or blue sky laws of the several states (including filing fees and the

reasonable fees and expenses of counsel for the Underwriters relating to such registration and qualification); (vi) any filings required to be made with the Financial Industry Regulatory Authority (“FINRA”) or the applicable Canadian securities regulatory authorities (including filing fees and the reasonable fees and expenses of counsel for the Underwriters relating to such filings); (vii) the transportation and other expenses incurred by or on behalf of Company representatives in connection with presentations to prospective purchasers of the Securities; (viii) the fees and expenses of the Company’s accountants and the fees and expenses of counsel (including local and special counsel) for the Company; and (ix) all other costs, fees and expenses incident to the performance by the Company of its obligations hereunder. It is understood, however, that except as provided in this subsection (l), and Sections 7 and 8 hereof, the Underwriters will pay all of their own costs and expenses, including fees and disbursements of their counsel, transfer taxes payable on the resale of any of the Securities by them, the transportation and other expenses incurred by or on their behalf in connection with presentations by Company representatives to prospective purchasers of Securities and any advertising expenses connected with any offers they may make.

(m) The Company will use the net proceeds received by it from the sale of the Securities in the manner specified in the Preliminary Final Prospectus and the Final Prospectus under “Use of Proceeds”.

The obligations of the Underwriters to purchase the Securities shall be subject to the accuracy of the representations and warranties on the part of the Company contained herein as of the Applicable Time and the Closing Date, to the accuracy of the statements of the Company made in any certificates pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions:

Without independent verification of the factual accuracy, completeness or fairness of any statements made in the Registration Statement, the Preliminary Final Prospectus and the Final Prospectus (except for the financial statements and financial schedules and other financial information included therein, as to which we express no opinion), each appear on its face to be appropriately responsive in all material respects to the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder;

The opinion of ▇▇▇▇▇▇▇ Coie LLP to be filed as Exhibit 8.1 to the Report on Form 6-K furnished to the Commission on or before the Closing Date, and to be incorporated by reference into the Registration Statement is confirmed and the Underwriters may rely on such as if it were addressed to them;

(v) Insofar as matters of United States Federal law are concerned, to such counsel’s knowledge, (i) there are no legal or governmental proceedings pending or threatened against the Company or to which the Company is a party or to which any of its properties is subject that are required to be described in the Registration Statement, the Preliminary Final Prospectus and the Final Prospectus but are not so described as required and (ii) there are no agreements, contracts, indentures, leases or other documents or instruments that are required to be described in the Registration Statement, the Preliminary Final Prospectus or the Final Prospectus or to be filed as exhibits to the Registration Statement that are not described or filed as required.;

(vi) The Company is not, and immediately upon receipt of payment for the Securities, and the application of the proceeds thereof as described in the Disclosure Package and the Final Prospectus, will not be, an “investment company” as defined in the Investment Company Act of 1940, as amended;

(viii) Without independent verification of the factual accuracy, completeness or fairness of any statements made therein, the documents incorporated or deemed to be incorporated by reference into the Registration Statement, the Preliminary Final Prospectus and the Final Prospectus (except for the financial statements and financial schedules, and other financial and statistical information included therein, as to which such counsel need express no opinion), when they became effective or were filed with the Commission, as the case may be, appear on their face to be appropriately responsive in all material respects to the requirements of the Exchange Act and the applicable rules and regulations of the Commission thereunder;

(ix) The issue and sale of the Securities will not (i) result in a breach or the imposition of any lien, charge or encumbrance upon any property or assets of the Company pursuant to the terms of any indenture, contract, lease, mortgage, deed of trust, note agreement, loan agreement or other agreement or instrument filed as an exhibit to the Registration Statement (including any document filed as an exhibit to any document incorporated by reference into the Registration Statement) to which the Company is a party or bound or to which its property is subject, which breaches or impositions of such lien, charge or encumbrance would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; or (ii) violate any statute, law, rule or regulation (other than U.S. federal securities, state or foreign securities or blue sky or anti-fraud statutes, laws, rules or regulations, laws and regulations relating to commodity (and other) futures and indices and other similar instruments, and the rules and regulations of FINRA), or any judgment, order or decree to the knowledge of such counsel applicable to the Company of any court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Company or any of its properties, which violations would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; and

(x) Except as disclosed in the Registration Statement, the Preliminary Final Prospectus and the Final Prospectus, to the knowledge of such counsel, no holders of securities of the Company have current rights to the registration of such securities under the Registration Statement.

In addition, such counsel shall state that, such counsel has participated in conferences with officers and other representatives of the Company, representatives of the Underwriters and representatives of the independent auditors of the Company at which the contents of the Registration Statement, the Preliminary Final Prospectus and the Final Prospectus and any amendments or supplements thereto were discussed. Such counsel shall state that, although such counsel assumes no responsibility for the factual accuracy, completeness or fairness of any statements (other than as set forth in paragraph (ii) and (iii) above, subject to the assumptions, exclusions and qualifications set forth in such counsel’s opinion) made in (a) the Registration Statement or any amendment thereto, (b) the Preliminary Final Prospectus or any amendment or supplement thereto, (c) the Final Prospectus or any amendment or supplement thereto, or (d) the documents incorporated by

reference in the Registration Statement or any further amendment or supplement thereto, nothing has come to such counsel’s attention that causes such counsel to believe that:

the Registration Statement or the prospectus included therein (except for the financial statements and financial schedules and other financial information included therein, as to which such counsel need not comment) as of its most recent Effective Date contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or

the Final Prospectus (except for the financial statements and financial schedules and other financial information included therein, as to which such counsel need not comment) as of its date, or as amended or supplemented, if applicable, as of the Closing Date contained or contains any untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or

In rendering such opinion, such counsel may (A) rely in respect of matters of fact upon certificates of officers and employees of the Company and the Manager and upon information obtained from public officials, (B) assume that all documents submitted to them as originals are authentic, that all copies submitted to them conform to the originals thereof, and that the signatures on all documents examined by them are genuine, and (C) state that their opinion is limited to United States Federal laws.

References to the Final Prospectus in this paragraph (d) shall also include any supplements thereto at the Closing Date.

(e) The Company shall have requested and caused Farris, Vaughan, ▇▇▇▇▇ & ▇▇▇▇▇▇ LLP, Canadian tax counsel for the Company, to have furnished to the Representatives their opinion, dated the Closing Date and addressed to the Representatives, to the effect that:

(i) All statements of legal conclusions contained under the caption “Non-United States Tax Consequences—Canadian Federal Income Tax Consequences” in the Preliminary Final Prospectus and the Final Prospectus and under the caption “Non-U.S. Tax Considerations—Canadian Federal Income Tax Consequences” in the Registration Statement and the Basic Prospectus are correct and accurate with respect to the matters set forth therein as of the Closing Date and such counsel is of the opinion that the statements under the caption “Non-United States Tax Consequences—Canadian Federal Income Tax Consequences” in the Preliminary Final Prospectus and the Final Prospectus and under the caption “Non-U.S. Tax Considerations—Canadian Federal Income Tax Consequences” in the Registration Statement and the Basic Prospectus, with respect to those matters as to which no legal conclusions are provided, is an accurate discussion of the Canadian federal income tax matters applicable to those holders who acquire Securities in connection with the offering thereof;

(ii) The statements set forth in the Preliminary Final Prospectus and the Final Prospectus under the caption “Business—Taxation of the Company—Canadian Taxation” accurately describes the Canadian income tax matters described therein; provided, however, with respect to the opinion referred to in the immediately preceding sentence only, such counsel need express no opinion or comment on any representation or statement of fact, intention or assumption, or of risk (except to the extent of any conclusion of law set out under such caption), or of a general nature (except to the extent of any conclusion of law set out under such caption), made by or on behalf of the Company in the Preliminary Final Prospectus or the Final Prospectus including, but without restricting the generality of the forgoing, the following statements under such caption: “It is not our current intention that our central management and control be exercised in Canada”; “Based on our operations, we do not believe that we are, nor do we expect to be, resident in Canada for purposes of the Canada Tax Act, and we intend that our affairs will be conducted and operated in a manner such that we do not become a resident of

Canada under the Canada Tax Act”; “A Canadian resident corporation that carries on an international shipping business, as described in the previous sentence, in the Republic of the ▇▇▇▇▇▇▇▇ Islands is exempt from income tax under the current laws of the Republic of the ▇▇▇▇▇▇▇▇ Islands”; and “We expect that we will qualify for these statutory exemptions under the Canada Tax Act. Based on our operations, we do not believe that we are, nor do we expect to be, carrying on a business in Canada for purposes of the Canada Tax Act other than a business that would provide us with these statutory exemptions from Canadian income tax”.

The opinion of such counsel set forth in the two preceding paragraphs is based on the provisions of the Canada Tax Act and the regulations thereunder in force as of the date of such opinion, all specific proposals to amend the Canada Tax Act and the regulations thereunder which have been publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date of such opinion (the “Proposed Amendments”) and such counsel’s understanding of existing case law and the current published administrative policies and assessing practices of the Canada Revenue Agency. There can be no assurance that the Proposed Amendments will be implemented in their current form or at all. Such opinion will not otherwise take into account or anticipate any changes in law, whether by legislative, governmental or judicial decision or action, and will not take into account provincial, territorial or foreign tax legislation or considerations;

References to the Final Prospectus in this paragraph (e) shall also include any supplements thereto at the Closing Date.

(iii) To the knowledge of such counsel, there is no pending or threatened action, suit or proceeding by or before any court or governmental agency, authority or body of the Republic of the ▇▇▇▇▇▇▇▇ Islands or any arbitrator involving the Company or its property of a character required to be disclosed in the Registration Statement which is not adequately disclosed in the Disclosure Package and the Final Prospectus; and the statements included in the 2010 Annual Report incorporated by reference into the Registration Statement, the Preliminary Final Prospectus and the Final Prospectus under the caption “Item 8. Financial Information—A. Financial Statements and Other Financial Information—Dividend Policy” and the statements included in the Preliminary Final Prospectus and the Final Prospectus under the caption “Description of Capital Stock” insofar as such statements constitute a summary of the terms of the capital stock of the Company, ▇▇▇▇▇▇▇▇ Islands legal matters, documents or proceedings referred to therein, and the statements in the Preliminary Final Prospectus and the Final Prospectus under the captions “Non-United States Tax Consequences—▇▇▇▇▇▇▇▇ Islands Tax Consequences”, “Risk Factors—Risks of Investing in the Series C Preferred Shares—Our ability to pay dividends on and to redeem our Series C Preferred Shares is limited by the requirements of ▇▇▇▇▇▇▇▇ Islands law.”, and “Enforceability of Civil Liabilities” insofar as such statements summarize ▇▇▇▇▇▇▇▇ Islands tax considerations, legal matters, agreements, documents or proceedings, accurately and fairly describe in all material respects such legal matters, agreements, documents or proceedings; provided, however, that such counsel need express no opinion with respect to the laws of Canada;

(iv) Insofar as matters of ▇▇▇▇▇▇▇▇ Islands law are concerned, the Registration Statement and the filing of the Registration Statement with the Commission have been duly authorized by and on behalf of the Company, and the Registration Statement has been duly executed pursuant to such authorization by and on behalf of the Company;

(v) Each of this Agreement and the Operative Agreements to which the Company is a party has been duly authorized, validly executed and delivered by the Company;

(vi) To the knowledge of such counsel, no permits of, or declarations or filings with, any governmental or regulatory authorities and all courts and other tribunals, in the Republic of the ▇▇▇▇▇▇▇▇ Islands, are required for the Company to own or lease, as the case may be, and to operate its properties and to carry on its business in the manner described in the Disclosure Package and the Final Prospectus;

(vii) No consent, registration or qualification under the laws of the Republic of the ▇▇▇▇▇▇▇▇ Islands is required for the offering, issuance and sale by the Company of the Common Shares, the execution, delivery and performance of this Agreement by the Company or the consummation of the transactions contemplated by this Agreement;

(viii) Neither the issue and sale of the Securities, the execution, delivery and performance of this Agreement, nor the consummation of any other of the transactions herein contemplated nor the fulfillment of the terms hereof will conflict with, result in a breach or violation of, or imposition of any lien, charge or encumbrance under ▇▇▇▇▇▇▇▇ Islands law upon any property or assets of the Company pursuant to (i) the articles of incorporation or by-laws of the Company or (ii) any ▇▇▇▇▇▇▇▇ Islands statute, law, rule, order, or regulation of general application to which the Company is subject;

(ix) All dividends and other distributions declared and payable on the shares of capital stock of the Company, including the Securities, may under the current laws and regulations of the Republic of the ▇▇▇▇▇▇▇▇ Islands be paid in United States dollars and may be freely transferred out of the Republic of the ▇▇▇▇▇▇▇▇ Islands, and all such dividends and other distributions will not be subject to withholding or other taxes under the laws and regulations of the Republic of the ▇▇▇▇▇▇▇▇ Islands and are otherwise free and clear of any other tax, withholding or deduction and without the necessity of obtaining any consents, approvals, authorizations, orders, licenses, registrations, clearances and qualifications of or with any court or governmental agency or body in the Republic of the ▇▇▇▇▇▇▇▇ Islands;

(x) No documentary, stamp or other issuance or transfer taxes or duties and no capital gains, income, withholding or other taxes are payable by or on behalf of the Underwriters to the Republic of the ▇▇▇▇▇▇▇▇ Islands or to any political subdivision or taxing authority thereof or therein in connection with the sale and delivery by the Company of the Securities to or for the respective accounts of the Underwriters or the sale and delivery by the Underwriters of the Securities to the initial purchasers thereof; and

(xi) The choice of law provision set forth in Section 14 hereof is legal, valid and binding under the laws of the Republic of the ▇▇▇▇▇▇▇▇ Islands and such counsel knows of no reason why the courts of the Republic of the ▇▇▇▇▇▇▇▇ Islands would not give effect to the choice of New York law as the proper law of this Agreement; the Company has the legal capacity to

▇▇▇ and be sued in its own name under the laws of the Republic of the ▇▇▇▇▇▇▇▇ Islands; the Company has the power to submit, and has irrevocably submitted, to the non-exclusive jurisdiction of the New York Courts and has validly and irrevocably appointed ▇▇▇▇▇▇▇ & Associates as its designee, appointee and authorized agent for the purpose described in Section 15 hereof under the laws of the Republic of the ▇▇▇▇▇▇▇▇ Islands; the irrevocable submission of the Company to the non-exclusive jurisdiction of the New York Courts, and assuming the Company is not regularly engaged in the conduct of activities pursuant to contractual arrangements with the Republic of the ▇▇▇▇▇▇▇▇ Islands or another sovereign jurisdiction or any division, bureau, office, agency, department or political subdivision thereof, the waivers by the Company of any immunity and any objection to the venue of the proceeding in a New York Court in this Agreement are legal, valid and binding under the laws of the Republic of the ▇▇▇▇▇▇▇▇ Islands and, assuming the foregoing, such counsel knows of no reason why the courts of the Republic of the ▇▇▇▇▇▇▇▇ Islands would not give effect to the submission and waivers; service of process in the manner set forth in Section 15 of this Agreement, will be effective to confer valid personal jurisdiction over the Company under the laws of the Republic of the ▇▇▇▇▇▇▇▇ Islands; and provided that the following provisions of the ▇▇▇▇▇▇▇▇ Islands Uniform Foreign Money-Judgments Recognition Act are complied with:

(a) the judgment was for a sum of money and was final in the jurisdiction;

(b) the court granting the judgment had jurisdiction under the laws of the place where it sat and the judgment did not offend principles of the Republic of the ▇▇▇▇▇▇▇▇ Islands as to due process, propriety or public order; and

(c) the defendant was actually present in person or by a duly appointed representative and the judgment did not constitute in effect a default judgment;

a final and conclusive judgment against the Company obtained in a New York court arising out of or in relation to the obligations of the Company under this Agreement would be enforceable in the courts of the Republic of the ▇▇▇▇▇▇▇▇ Islands without a retrial on the merits and so long as the provisions of the Republic of the ▇▇▇▇▇▇▇▇ Islands Uniform Foreign Money-Judgments Recognition Act are complied with.

In rendering such opinion, such counsel may (A) rely in respect of matters of fact upon certificates of officers and employees of the Company and the Manager and upon information obtained from public officials, (B) assume that all documents submitted to them as originals are authentic, that all copies submitted to them conform to the originals thereof, and that the signatures on all documents examined by them are genuine, and (C) state that their opinion is limited to the laws of the Republic of the ▇▇▇▇▇▇▇▇ Islands. References to

the Final Prospectus in this paragraph (f) shall also include any supplements thereto at the Closing Date.

(g) The Company shall have requested and caused ▇▇▇▇▇▇, ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, United Kingdom counsel for the Company, to have furnished to the Representatives their opinion, dated the Closing Date and addressed to the Representatives, to the effect that:

(i) The statements set forth in the 2010 Annual Report and incorporated by reference into the Registration Statement, the Preliminary Final Prospectus and the Final Prospectus under the caption “Item 5. Operating and Financial Review and Prospects—C. Liquidity and Capital Resources—Financing Facilities”, when read together with (A) the statements set forth in the Company’s Report on Form 6-K, filed with the Commission on May 6, 2011 and incorporated by reference into the Registration Statement, the Preliminary Final Prospectus and the Final Prospectus under the caption “Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources” and (B) the statements in the Preliminary Final Prospectus and the Final Prospectus under the caption “Financing Facilities”, insofar as they purport to describe specific features of the $400.0 Million UK Lease Facility, comprise a materially accurate summary of what they describe, except that no opinion is expressed with respect to the laws of the Republic of the ▇▇▇▇▇▇▇▇ Islands or the laws of New York, United States.

In rendering such opinion, such counsel may (A) rely in respect of matters of fact upon certificates of officers and employees of the Company and the Manager and upon information obtained from public officials, (B) assume that all documents submitted to them as originals are authentic, that all copies submitted to them conform to the originals thereof, and that the signatures on all documents examined by them are genuine, and (C) state that their opinion is limited to the laws of the United Kingdom. References to the Final Prospectus in this paragraph (g) shall also include any supplements thereto at the Closing Date.

(h) The Representatives shall have received from Cravath, Swaine & ▇▇▇▇▇ LLP, counsel for the Underwriters, such opinion or opinions, dated the Closing Date and addressed to the Representatives, with respect to the issuance and sale of the Securities, the Registration Statement, the Disclosure Package, the Final Prospectus (together with any supplement thereto) and other related matters as the Representatives may reasonably require, and the Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

(i) The Company shall have furnished to the Representatives a certificate of the Company, signed by the Chairman of the Board or the President and the principal financial or accounting officer of the Company, dated the Closing Date to the effect that the signers of such certificate have carefully examined the Registration

Statement, the Final Prospectus, the Disclosure Package and any supplements or amendments thereto and this Agreement and that:

(i) the representations and warranties of the Company in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date;

(ii) no stop order suspending the effectiveness of the Registration Statement or any notice that would prevent its use has been issued and no proceedings for that purpose have been instituted or, to the Company’s knowledge, threatened; and

(iii) since the date of the most recent financial statements included or incorporated by reference in the Final Prospectus (exclusive of any supplement thereto), there has been no Material Adverse Effect, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Prospectus (exclusive of any supplement thereto).

(j) The Company shall have requested and caused KPMG LLP to have furnished to the Representatives, at the date hereof and at the Closing Date, letters, dated respectively as of the date hereof and as of the Closing Date, in form and substance satisfactory to the Representatives, confirming that they are the independent registered public accounting firm of the Company within the meaning of the Act and the Exchange Act and the applicable rules and regulations thereunder adopted by the Commission and the Public Company Accounting Oversight Board (United States) (the “PCAOB”), and that they have performed a review of the unaudited interim consolidated financial information of the Company as at March 31, 2011, and for the three-month periods ended March 31, 2011 and 2010 in accordance with the PCAOB standards for a review of interim financial information as described in ▇▇ ▇▇▇, ▇▇▇▇▇▇▇ Financial Information, and stating in effect that:

(i) in their opinion, the audited consolidated financial statements incorporated by reference into the Registration Statement, the Preliminary Final Prospectus and the Final Prospectus and reported on by them comply as to form, in all material respects, with the applicable accounting requirements of the Act and the Exchange Act and the related rules and regulations adopted by the Commission;

(ii) on the basis of: a reading of the latest unaudited financial statements made available by the Company; their limited review, in accordance with the standards established under PCAOB AU 722, of the unaudited interim consolidated financial statements for the three-month period ended March 31, 2011 and as at March 31, 2011; carrying out certain specified procedures (but not an examination in accordance with generally

accepted auditing standards) which would not necessarily reveal matters of significance with respect to the comments set forth in such letter; a reading of the minutes of the meetings of shareholders, directors and any committees of the Company; and inquiries of certain officials of the Company who have responsibility for financial and accounting matters of the Company as to transactions and events subsequent to March 31, 2011, nothing came to their attention which caused them to believe that:

(1) any material modifications should be made to said unaudited interim consolidated financial statements incorporated by reference into the Registration Statement, the Preliminary Final Prospectus and the Final Prospectus for them to be in conformity with generally accepted accounting principles; or said unaudited financial statements do not comply as to form in all material respects with the applicable accounting requirements of the Act and the Exchange Act and the related rules and regulations adopted by the Commission; or

(2) with respect to the period subsequent to March 31, 2011, there were any changes, at a specified date not more than five days prior to the date of the letter, in the capital stock of the Company, increases in long-term debt, decreases in net current assets or the shareholders’ equity, of the Company, as compared with the amounts shown on the March 31, 2011 combined balance sheet included in the Registration Statement, the Preliminary Final Prospectus and the Final Prospectus, or for the period from April 1, 2011 to such specified date there were any decreases, as compared with the comparative period in the preceding year, in net revenue or net earnings of the Company, except in all instances for changes or decreases set forth in the Registration Statement, the Preliminary Final Prospectus and the Final Prospectus or in such letter, in which case the letter shall be accompanied by an explanation by the Company as to the significance thereof unless said explanation is not deemed necessary by the Representatives; and

(iii) they have performed certain other specified procedures as a result of which they determined that certain information of an accounting, financial or statistical nature (which is limited to accounting, financial or statistical information derived from the general accounting records of the Company and its predecessor) set forth in the Registration Statement, the Preliminary Final Prospectus and the Final Prospectus agrees with the financial statements included in the Registration Statement, the Preliminary Final Prospectus and the Final Prospectus, the accounting records of the Company and its predecessor, or to other financial information provided by the Company, in which case the sources of such other financial information shall be described, excluding any questions of legal interpretation.

References to the Final Prospectus in this paragraph (j) include any supplement thereto at the date of the letter.

(k) Subsequent to the Applicable Time or, if earlier, the dates as of which information is given in the Registration Statement (exclusive of any amendment thereof) and the Final Prospectus (exclusive of any supplement thereto), there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraph (j) of this Section 6 or (ii) any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), earnings, business or properties of the Company and its subsidiaries taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Prospectus (exclusive of any supplement thereto) the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Representatives, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Registration Statement (exclusive of any amendment thereof) and the Disclosure Package and the Final Prospectus (exclusive of any supplement thereto).

(l) Prior to the Closing Date, the Company shall have furnished to the Representatives such further information, certificates and documents as the Representatives may reasonably request.

(m) Subsequent to the Applicable Time, there shall not have been any decrease in the rating of any of the Company’s securities by any “nationally recognized statistical rating organization” (as defined for purposes of Section (3)(a)(62) under the Exchange Act) or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change.

(n) The Securities shall have been listed and admitted and authorized for trading on The New York Stock Exchange, and satisfactory evidence of such actions shall have been provided to the Representatives.

(o) On the Closing Date, all of the Operative Agreements will remain in full force and effect.

If any of the conditions specified in this Section 6 shall not have been fulfilled when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance to the Representatives and counsel for the Underwriters, this Agreement and all obligations of the Underwriters hereunder may be canceled at, or at any time prior to, the Closing Date by the Representatives. Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing.

The documents required to be delivered by this Section 6 shall be delivered at the office of Cravath, Swaine & ▇▇▇▇▇ LLP, counsel for the Underwriters, at Worldwide Plaza, ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇, on the Closing Date.

7. Reimbursement of Underwriters’ Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters severally through the Representatives on demand for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been actually incurred by them in connection with the proposed purchase and sale of the Securities.

8. Indemnification and Contribution. (a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement for the registration of the Securities as originally filed or in any amendment thereof, or in the Basic Prospectus, any Preliminary Final Prospectus, the Final Prospectus, any Issuer Free Writing Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement, and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as referred to in subsection (a) in the foregoing indemnity from the Company to each Underwriter, but only with reference to written information furnished to the Company by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The

Company acknowledges that the statements set forth in the last paragraph of the cover page regarding delivery of the Securities, the name of each Underwriter on the cover page and, under the caption “Underwriting”, (i) the list of Underwriters and their respective participation in the sale of the Securities, (ii) the sentences related to concessions and reallowances and (iii) the paragraphs related to stabilization, syndicate covering transactions and penalty bids in any Preliminary Final Prospectus and the Final Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ one separate counsel (in addition to local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (w) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (x) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (y) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (z) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release and no admission of fault of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriters on the other from the offering of the Securities; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company, on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company, within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company subject in each case to the applicable terms and conditions of this paragraph (d).

9. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the

amount of Securities set forth opposite their names in Schedule II hereto bears to the aggregate amount of Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of Securities set forth in Schedule II hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter or the Company. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement and the Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in the Common Shares or the Series C Preferred Shares shall have been suspended by the Commission or The New York Stock Exchange, (ii) trading in securities generally on The New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such Exchange, (iii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iv) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Final Prospectus (exclusive of any supplement thereto).

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 5(l), 7, 8 and 15 hereof shall survive the termination or cancellation of this Agreement.

13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, director nominees, employees, agents and controlling persons referred to in Section 8 hereof, and no other person will have any right or obligation hereunder.

15. Jurisdiction. The Company agrees that any suit, action or proceeding against the Company brought by any Underwriter, the directors, officers, employees and agents of any Underwriter, or by any person who controls any Underwriter, arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any New York Court, and waives any objection which it may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submits to the non-exclusive jurisdiction of such courts in any suit, action or proceeding. The Company has appointed ▇▇▇▇▇▇▇ & Associates as its authorized agent (the “Authorized Agent”) upon whom process may be served in any suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated herein which may be instituted in any New York Court, by any Underwriter, the directors, officers, employees and agents of any Underwriter, or by any person who controls any Underwriter, and expressly accepts the non-exclusive jurisdiction of any such court in respect of any such suit, action or proceeding. The Company hereby represents and warrants that the Authorized Agent has accepted such appointment and has agreed to act as said agent for service of process, and the Company agrees to take any and all action, including the filing of any and all documents that may be necessary to continue such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent shall be deemed, in every respect, effective service of process upon the Company. Notwithstanding the foregoing, any action arising out of or based upon this Agreement may be instituted by any Underwriter, the directors, officers, employees and agents of any Underwriter, or by any person who controls any Underwriter, in any court of competent jurisdiction in the Republic of the ▇▇▇▇▇▇▇▇ Islands.

The provisions of this Section 15 shall survive any termination of this Agreement, in whole or in part.

16. Waiver of Immunity. To the extent that the Company has or hereafter may acquire any immunity (sovereign or otherwise) from any legal action, suit or proceeding, from jurisdiction of any court or from set-off or any legal process (whether service or notice, attachment in aid or otherwise) with respect to itself or any of its property,
