Ladies and Gentlemen:

Seaspan Corporation, a corporation organized under the laws of the Republic of the ▇▇▇▇▇▇▇▇ Islands (the “Company”), proposes to sell to the several underwriters named in Schedule II hereto (the “Underwriters”), for whom you (the “Representatives”) are acting as representatives, the number of common shares, $.01 par value set forth in Schedule I hereto (the “Common Shares”) of the Company (said shares to be issued and sold by the Company being hereinafter called the “Underwritten Securities”). The Company also proposes to grant to the Underwriters an option to purchase up to the number of additional Common Shares set forth in Schedule I hereto to cover over-allotments (the “Option Securities”; the Option Securities, together with the Underwritten Securities, being hereinafter called the “Securities”). 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.

Prior to this Agreement, the Company has also entered into agreements (the “Subscription Agreements”) providing for the sale by the Company (the “Concurrent Sale”) of a total of $18,074,925 of Common Shares (or a total of 663,300 Common Shares) (the “Concurrent Securities”) to certain of its executive officers and directors, certain affiliates of the Manager and certain of their executive officers, and the ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇ Revocable Living Trust (collectively, the “Purchasers in the Concurrent Sale”) at the public offering price set forth in the Final Prospectus (as defined below). The Company is offering the Concurrent

Securities directly to the Purchasers in the Concurrent Sale. The Underwriters will receive no underwriting discounts or commissions on the Concurrent Securities. The Company acknowledges and agrees with the Underwriters that as between the Company on the one hand and the Underwriters on the other, the Company is the sole beneficiary of the Concurrent Sale and that none of the Underwriters has provided any services to the Company as to the structure or execution of the Concurrent Sale.

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 an automatic 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. Such Registration Statement, including any amendments thereto filed prior to the Execution Time, became effective upon filing. 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. 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 Execution Time or, to the extent not completed at the Execution 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 Execution Time, will be included or made therein. The Registration Statement, at the Execution 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 the 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) and on any date on which Option Securities are purchased, if such date is not the Closing Date (a “settlement date”), 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 and at the Execution Time, 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 or omitted from 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.

(c) The Disclosure Package when taken together as a whole, does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Disclosure Package 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.

(d) (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Sections 13 or 15(d) of the Exchange Act or form of prospectus), (iii) at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Securities in reliance on the exemption in Rule 163, and (iv) at the Execution Time (with such date being used as the determination date for purposes of this clause (iv)), the Company was or is (as the case may be) a “well-known seasoned issuer” as defined in Rule 405. The Company agrees to pay the fees required by the Commission relating to the Securities within the time required by Rule 456(b)(1) without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r).

(e) (i) At the earliest time after the filing of the Registration Statement that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) of the Act) and (ii) as of the Execution Time (with such date being used as the determination date for purposes of this clause (ii)), the Company was not and is not an Ineligible Issuer (as defined in Rule 405), without taking account of any determination by the Commission pursuant to Rule 405 that it is not necessary that the Company be considered an Ineligible Issuer.

(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 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 when the Final Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b), (3) when, prior to termination of the offering of the Securities, any amendment to the Registration Statement shall have been filed or become effective, (4) 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, (5) 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 (6) 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 best 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 best 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 (1) notify the Representatives of such event, (2) 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, (3) use its best 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 (4) 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.

(j) The Company will comply with all applicable securities and other laws, rules and regulations in each jurisdiction in which the Concurrent Securities are offered in connection with the Concurrent Sale.

(l) The Company will offer between a minimum total of $18,074,925 and a maximum total of $20,000,000 of Common Shares in the Concurrent Sale and will not terminate the Concurrent Sale without the prior written consent of the Representatives.

Moreover, as a non-resident of Canada we may have to pay tax in Canada on our Canadian source income, which could reduce our earnings” 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 description of such Canadian tax risk factor), or of a general nature (except to the extent of any conclusion of law set out under such description of such Canadian tax risk factor), 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 description of such Canadian tax risk factor: “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 business in the Republic of the ▇▇▇▇▇▇▇▇ Islands is exempt from income tax under the current laws of the Republic of the ▇▇▇▇▇▇▇▇ Islands”; “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”.

(v) Each of the Management Agreements has been duly authorized, validly executed and delivered by the Ship Manager. Assuming the due authorization, valid execution and delivery thereof by the other applicable parties thereto and that each such other party has the power and capacity to enter into and perform its obligations thereunder, each of the Management Agreements is a valid and binding agreement of each such party and is enforceable against each such party in accordance with its respective terms, subject to (i) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law); (ii) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant of good faith and fair dealing; and (iii) such other assumptions and qualifications as are reasonably acceptable to the Underwriters or their counsel.

In rendering such opinion, such counsel may (A) rely in respect of matters of fact upon certificates of officers and employees of the Company, the Manager, the Ship Manager and Seaspan International 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 British Columbia and the laws of Canada applicable thereunder.

(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 or the Concurrent 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, regulation of general application to which the Company is subject;

(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:

(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; and 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.

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.

(i) The statements set forth in the 2007 Annual Report and incorporated by reference into the Registration Statement, the Preliminary Final Prospectus and the Final Prospectus under the caption “Item 4.

Business Overview—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 redering 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.

(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

(h) The Company shall have requested and caused KPMG LLP to have furnished to the Representatives, at the Execution Time and at the Closing Date, and the Option Closing Date, if applicable, letters, dated respectively as of the Execution Time and as of the Closing Date, and the Option Closing Date, if applicable, 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 stating in effect that:

(i) in their opinion, the audited combined financial statements included in 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 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 December 31, 2007, nothing came to their attention which caused them to believe that:

(1) with respect to the period subsequent to December 31, 2007, 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 December 31, 2007 combined balance sheet included in the Registration Statement, the Preliminary Final

Prospectus and the Final Prospectus, or for the period from January 1, 2008 to such specified date there were any decreases, as compared with 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; or

(2) the information included in the Registration Statement, the Preliminary Final Prospectus and the Final Prospectus in response to Form 20-F, Item 3A (Selected Financial Data), is not in conformity with the applicable disclosure requirements of Form F-3 and Form 20-F;

(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 (h) include any supplement thereto at the date of the letter.

(i) Subsequent to the Execution 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 (g) 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).

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

(m) At the Execution Time, the Company shall have furnished to the Representatives a letter substantially in the form of Exhibit A hereto from each person and entity listed on Annex A hereto, addressed to the Representatives.

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)(1) in the foregoing indemnity from the Company to each Underwriter, but only with reference to written information relating to such Underwriter 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 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 for inclusion in any Preliminary Final Prospectus or the Final Prospectus.

(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 (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) 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, (iii) 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 (iv) 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).

(e) 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 the Concurrent Sale.

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 Underwritten Securities set forth opposite their names in Schedule II hereto bears to the aggregate amount of Underwritten Securities set forth opposite the names of all the remaining Underwriters) the Underwritten Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate amount of Underwritten Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of Underwritten 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 Underwritten Securities, and if such nondefaulting Underwriters do not purchase all the Underwritten 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 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 7 and 8 hereof shall survive the termination or cancellation of this Agreement.
