The Securities were originally issued pursuant to an indenture, dated as of December 15, 1996, between State Street Corporation, a Massachusetts corporation (the “Company”) and U.S. Bank National Association, as trustee (“U.S. Bank” and, in such capacity, the “Trustee”) (as successor in interest to various predecessor trustees) (the “Base Indenture”), as supplemented by the Third Supplemental Indenture, dated as of January 25, 2008, between the Company and the Trustee (the “Supplemental Indenture” and, together with the Base Indenture and, following the execution thereof, the Supplemental Indenture Amendment (as defined below), the “Indenture”). The Trust purchased the Securities with the proceeds of the sale of the Trust’s 8.250% Fixed-to-Floating Rate Normal Automatic Preferred Enhanced Capital Securities, liquidation amount $1,000 per security (the “Normal APEX”) and the Trust’s Common Securities, $100,000 aggregate liquidation amount (the “Trust Common Securities”).

The Trust, acting through the Property Trustee (as defined below), has also entered into (i) a Stock Purchase Contract Agreement, dated as of January 25, 2008, with the Company (the “Stock Purchase Contract Agreement”), pursuant to which the Company has issued to the Trust 5,001 Stock Purchase Contracts (each, a “Stock Purchase Contract”), each having a stated amount of $100,000 and obligating the Trust to purchase from the Company, and the Company to sell to the Trust, subject to the terms thereof, one share of the Company’s Non-Cumulative Perpetual Preferred Stock, Series A, $100,000 liquidation preference and no par value per share (the “Preferred Stock”), on the Stock Purchase Date provided for (and as defined) in the Stock Purchase Contract Agreement, and (ii) a Collateral Agreement, dated as of January 25, 2008 (the “Collateral Agreement”), among itself, the Company and U.S. Bank, as collateral agent (in such capacity, the “Collateral Agent”), custodial agent (in such capacity, the “Custodial Agent”), securities intermediary (in such capacity, the “Securities Intermediary”) and securities registrar (in such capacity, the “Securities Registrar”), under which the Trust has pledged the Securities to secure its obligation to purchase Preferred Stock under the Stock Purchase Contracts.

In connection with the Trust’s obligation to purchase the Company’s Preferred Stock, the Securities must be remarketed as specified in the Supplemental Indenture, the Collateral Agreement and the Amended and Restated Trust Agreement, dated as of January 25, 2008 (the “Trust Agreement” and, together with the Supplemental Indenture and the Collateral Agreement, the “Remarketing Transaction Agreements”), among the Company, U.S. Bank (in such capacity, the “Property Trustee”) and U.S. Bank National Trust Association, as Delaware Trustee. The Company and the Trust have entered into a Remarketing Agreement, dated as of February 1, 2011 (the “Remarketing Agreement”), among themselves and ▇▇▇▇▇▇▇, ▇▇▇▇▇ & Co. (in such capacity, the “Remarketing Agent”), pursuant to which the Remarketing Agent is conducting the Remarketing of the Securities in accordance with the Remarketing Transaction Agreements. Upon completion of a Successful Remarketing, the terms of the Securities will be modified as set forth in notices from the Company to U.S. Bank, in its respective capacities as the Collateral Agent, the Custodial Agent, the Property Trustee (on behalf of the Trust) and the Trustee (the “Notices”), issued in January 2011 pursuant to Section 4.2 of the Supplemental Indenture and Section 5.18 of the Trust Agreement. In connection with the Remarketing, the Company will execute an amendment to the Supplemental Indenture (the “Supplemental Indenture Amendment”) to reflect any modifications to the terms of the Securities pursuant to the Remarketing and to issue a new global note in a form reflecting such modifications.

Capitalized terms used and not defined in this Agreement shall have the meanings set forth in the Indenture, the Trust Agreement, the Stock Purchase Contract Agreement or the Collateral Agreement, as applicable.

For so long as a prospectus relating to the Securities is (or but for the exemption in Rule 172 would be) required to be delivered under the Act by the Underwriter or any dealer, the Company will promptly advise the Underwriter of any proposal to amend or supplement the Registration Statement or any Statutory Prospectus at any time and will offer the Underwriter a reasonable opportunity to comment on any such amendment or supplement; and the Company will also advise the Underwriter promptly of (i) the filing of any such amendment or supplement, (ii) any request by the Commission or its staff for any amendment to the Registration Statement, for any supplement to any Statutory Prospectus or for any additional information, (iii) the institution by the Commission of any stop order proceedings in respect of the Registration Statement or the threatening of any proceeding for that purpose, and (iv) the receipt by the Company or the Trust of any notification with respect to the suspension of the qualification of the Securities in any jurisdiction or the institution or threatening of any proceedings for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof.

(c) Continued Compliance with Securities Laws. If, at any time when a prospectus relating to the Securities is (or but for the exemption in Rule 172 would be) required to be delivered under the Act by the Underwriter or any dealer, any event occurs as a result of which the Final Prospectus as then amended or supplemented would include an 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 is necessary at any time to amend the Registration Statement or supplement the Final Prospectus to comply with the Act, the Company will promptly notify the Underwriter of such event and will promptly prepare and file with the Commission and furnish, at the Company’s expense, to the Underwriter and any other dealers upon request of the Underwriter, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance. Neither the Underwriter’s consent to, nor the Underwriter’s delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 7 hereof.

(d) Reporting Requirements. For so long as the delivery of a prospectus is required in connection with the offering or sale of the Securities, the Company will furnish, or will cause to be furnished, to the Underwriter, as soon as practicable after the end of each fiscal year, a copy of any annual report to stockholders for such year as is required to be filed by the Company and the Trust with the Commission; and the Company and the Trust will furnish, or cause to be furnished, to the Underwriter (i) as soon as available, a copy of each report and any definitive proxy statement of the Company or the Trust filed with the Commission under the Exchange Act or mailed to stockholders, and (ii) from time to time, such other information concerning the Company or the Trust as the Underwriter may reasonably request. However, so long as the Company or the Trust is subject to the reporting requirements of either Section 13 or Section 15(d) of the Exchange Act and is timely filing reports with the Commission on its Electronic Data Gathering, Analysis and Retrieval system (“▇▇▇▇▇”), they are not required to furnish such reports or statements to the Underwriter.

(e) Blue Sky Qualifications. The Company and the Trust will promptly from time to time take such action as the Underwriter may reasonably request to qualify the Securities for offering and sale under the securities laws of such jurisdictions as the Underwriter may request and to comply with such laws so as to permit the sales and dealings therein in such jurisdictions for as long as may be necessary to complete the distribution of the Securities; provided that in connection therewith the Company shall not be required to qualify as a foreign corporation, to file a general consent to service of process in any jurisdiction or to subject itself to taxation in any jurisdiction.

(f) Furnishing of Prospectuses. Prior to 5:00 p.m., New York City time, on the New York business day next succeeding the date of this Agreement and so long as delivery of a prospectus by the Underwriter or any dealer may be (or but for the exception in Rule 172 would be) required under the Act, the Company will furnish, or cause to be furnished, to the Underwriter written and electronic copies of the Registration Statement, including all exhibits, any Statutory Prospectus, the Final Prospectus and all amendments and supplements to such documents, in New York City in such quantities as the Underwriter may reasonably request.

(g) Rule 158. The Company will make generally available to its securityholders as soon as practicable, but in any event not later than eighteen months after the effective date of the Registration Statement (as defined in Rule 158(c)), an earnings statement of the Company and its subsidiaries (and the Trust if required by the Commission) (which need not be audited) complying with Section 11(a) of the Act and the Rules and Regulations (including, at the option of the Company, Rule 158).

(h) Restrictions on Sales of Debt Securities. During the period beginning from the date hereof and continuing to and including the business day after the date of the Closing Date, the Trust shall not, and in the case of the Company shall not and shall not cause the Trust to, offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of, except as provided hereunder, any debt securities of the Company or the Bank (other than (i) the Securities, (ii) commercial paper issued in the ordinary course of business, (iii) certificates of deposit issued in the ordinary course of business, (iv) debt securities issued in connection with overnight Federal Reserve Bank transactions and (v) debt securities issued with the prior written consent of the Underwriter).

(i) Use of Proceeds. The Trust shall use the net proceeds it receives from the maturity of the Remarketing Treasury Securities, and the Company shall cause the Trust to use the net proceeds the Trust receives from the maturity of the Remarketing Treasury Securities, in the manner specified in the General Disclosure Package under the caption “Use of Proceeds.” The Company shall use the net proceeds it receives from the sale of the Preferred Stock to the Trust in the manner specified in the General Disclosure Package under the caption “Use of Proceeds.”

(j) [Reserved]

(k) Company License. The Company, upon request of the Underwriter, will furnish, or cause to be furnished, to the Underwriter an electronic version of the Company’s trademarks, servicemarks and corporate logo for use on the website, if any, operated by the Underwriter for the purpose of facilitating the on-line offering of the Securities (the “License”); provided, however, that the License shall be used solely for the purpose described above, is granted without any fee and may not be assigned or transferred.

(l) Payment of Expenses. The Company will pay or cause to be paid the following: (i) the costs, expenses, fees and taxes in connection with the registration, sale and delivery of the Securities, including any transfer taxes and stamp or similar duties, and the fees, disbursements and expenses of the Company’s and the Trust’s counsel and accountants in connection with the registration of the Securities under the Act and all other expenses in connection with the preparation, printing and filing of the Registration Statement, any Statutory Prospectus and amendments and supplements thereto and any Issuer Free Writing Prospectus and the mailing and delivering of copies thereof to the Underwriter and any dealers; (ii) the cost of printing or producing any agreement among underwriters, this Agreement, any Blue Sky Memoranda, closing documents (including any compilations thereof) and any other documents in connection with the offering, purchase, sale and delivery of the Securities; (iii) all expenses in connection with the qualification of the Securities for offering and sale under state securities laws as provided in Section 5(e) hereof, including the reasonable fees and disbursements of counsel for the Underwriter in connection with such qualification and in connection with the Blue Sky survey(s); (iv) any fees charged by securities rating agencies for rating the Securities; (v) the filing fees incident to, and the reasonable fees and disbursements of counsel for the Underwriter in connection with, any required review by the Financial Industry Regulatory Authority, Inc. of the terms of the sale of the Securities; (vi) the cost of preparing the Securities; (vii) the fees and expenses of the Trustee and any of its respective agents, and the fees and disbursements of counsel for the Trustee; and (viii) all other costs and expenses incident to the performance of its obligations hereunder and under the Transaction Documents which are not otherwise specifically provided for in this Section. It is understood, however, that, except as provided in this Section, and Sections 8 and 9 hereof, the Underwriter will pay all of its own costs and expenses, including the fees of its counsel, transfer taxes on resale of any of the Securities by it, and any advertising expenses connected with any offers it may make.

(m) Absence of Manipulation. Neither the Trust nor the Company will take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in stabilization or manipulation of the price of any securities of the Trust or the Company to facilitate the sale or resale of the Securities.

6. Free Writing Prospectuses. (a) Issuer Free Writing Prospectuses. The Company represents and agrees that, unless it obtains the prior consent of the Underwriter, and the Underwriter represents and agrees that, unless it obtains the prior 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 with the Commission. Any such free writing prospectus consented to by the Company is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping.

(b) Term Sheet. The Company will prepare, or cause to be prepared, a final term sheet relating to the Securities, containing only information that describes the final terms of the Securities and otherwise in a form consented to by the Underwriter, and will file such final term sheet within the period required by Rule 433(d)(5)(ii) following the date such final terms have been established for the offering of the Securities. Any such final term sheet is an Issuer Free Writing Prospectus and a Permitted Free Writing Prospectus for purposes of this Agreement. The Company and the Trust also consent to the use by the Underwriter of a free writing prospectus that contains only (i)(x) information describing the preliminary terms of the Securities or their offering or (y) information that describes the final terms of the Securities or their offering and that is included in the final term sheet of the Company contemplated in the first sentence of this subsection or (ii) other information that is not “issuer information,” as defined in Rule 433, it being understood that any such free writing prospectus referred to in clause (i) or (ii) above shall not be an Issuer Free Writing Prospectus for purposes of this Agreement.

7. Conditions of the Obligations of the Underwriter. The obligations of the Underwriter to purchase and pay for the Securities on the Closing Date will be subject to the accuracy of the representations and warranties of the Company herein (as though made on the Closing Date), to the accuracy of the statements of Company officers made pursuant to the provisions hereof, to the performance by the Company and the Trust of each of their obligations hereunder and to the following additional conditions precedent:

No stop order suspending the effectiveness of the Registration Statement or any part thereof shall have been issued and no proceedings for that purpose shall have been initiated or, to the knowledge of the Company or the Trust or the Underwriter, threatened or shall be contemplated by the Commission and no notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Act shall have been received; no stop order suspending or preventing the use of the Final Prospectus or any Issuer Free Writing Prospectus shall have been initiated or, to the knowledge of the Company or the Trust or the Underwriter, threatened by the Commission; and all requests for additional information on the part of the Commission shall have been complied with to the reasonable satisfaction of the Underwriter.

To the best of such counsel’s knowledge and other than as set forth in the General Disclosure Package, there are no pending, threatened or contemplated legal or governmental actions, suits or proceedings to which the Company or any of its subsidiaries is a party or of which any property of the Company or any of its subsidiaries is the subject, which, taking into account the likelihood of the outcome, the damages or other relief sought and other relevant factors, individually or in the aggregate, would reasonably be expected to result in any material adverse change in or affecting the general affairs, management, financial position or stockholders’ equity of the Company and its subsidiaries taken as a whole.

(ii) Compliance. The documents incorporated by reference in the General Disclosure Package and Final Prospectus or any further amendment or supplement thereto prior to such Closing Date (other than the financial statements and related schedules and other financial and accounting data therein, as to which such counsel expresses no opinion), when they became effective or were filed with the Commission, as the case may be, complied as to form in all material respects with the requirements of the Act or the Exchange Act, as applicable, and the Rules and Regulations.

The Securities, as modified after the Remarketing, have been duly authorized, executed and delivered by the Company and, when authenticated by the Trustee in accordance with the provisions of the Indenture and delivered to and paid for by the purchasers thereof in accordance with the terms of this Agreement, the Securities will be legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms; such Securities will be entitled to the benefits of the Indenture; and the Securities when sold to the purchasers thereof in accordance with the terms of this Agreement will conform in all material respects to the description thereof in the General Disclosure Package and the Final Prospectus.

(v) Capitalization of the Company. The Company has an authorized capitalization as is set forth in the General Disclosure Package and Final Prospectus.

(vi) Absence of Defaults and Conflicts. The execution and delivery of this Agreement, the Remarketing Agreement and the Indenture by the Company do not and the consummation by the Company of the transactions contemplated thereby will not (A) conflict with or constitute a breach of any of the terms or provisions of, or a default under, the Articles of Organization, By-laws or any agreement or instrument listed on a schedule to such opinion or (B) violate or conflict with any United States federal law, Massachusetts state law or New York state law, rule or regulation that in such counsel’s experience is normally applicable in transactions of the type contemplated by this Agreement, or any judgment, order or decree specifically naming the Company of which such counsel is aware.

(viii) Accurate Disclosure. (A) The statements set forth in the General Disclosure Package and the Final Prospectus under the captions “Description of the Remarketed Debentures”, insofar as such statements summarize the terms of the Securities and the Indenture, are correct in all material respects; and (B) the statements set forth in the General Disclosure Package and Final Prospectus under the caption “Certain U.S. Federal Tax Considerations”, insofar as such statements constitute matters of law or legal conclusions, are correct in all material respects, taking into account all of the terms of the Securities.

(ix) Investment Company Act. The Company is not and, after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described in the General Disclosure Package or Final Prospectus, will not be an “investment company,” as such term is defined in the Investment Company Act of 1940, as amended.

(x) Disclosure. While the limitations inherent in the independent verification of factual matters and the character of determinations involved in the registration process are such that such counsel is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the General Disclosure Package or the Final Prospectus (except to the extent expressly set forth in Section 7(d)(ix) hereof), subject to the foregoing and based on such participation and discussions: (A) The Registration Statement as of the date of its filing with the Commission and the Final Prospectus, as of the date of such opinion (except for the financial statements, including the notes and schedules thereto, and other financial and accounting data included therein or omitted therefrom, as to which such counsel expresses no view), appear on their 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; and (B) no facts have come to such counsel’s attention that have caused such counsel to believe that (i) the Registration Statement, as of the Applicable Time, contained an 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 (except as set forth in the parenthetical in clause (A) above), (ii) the General Disclosure Package, as of the Applicable Time, contained an untrue statement of a material fact or omitted 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 (except as set forth in the parenthetical in clause (A) above) or (iii) the Final Prospectus, as of the date of the Final Prospectus or as of the date of such opinion, contained or contains an untrue statement of a material fact or omitted or omits 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 (except as set forth in the parenthetical in clause (A) above).

Upon (a) delivery of the Securities to Cede & Co. or such other nominee as may be designated by DTC, (b) such Securities being credited to one or more securities accounts maintained by DTC for the Underwriter and (c) payment for such Securities being made as provided in this Underwriting Agreement, the Underwriter will acquire a securities entitlement (within the meaning of Sections 8-102(a)(17) and 8-501 of the UCC) in such Securities and no action based on an adverse claim (within the meaning of Section 8-102(a)(1) of the UCC) may be asserted against the Underwriter with respect to such securities entitlement.

(e) Accountants’ Comfort Letter. The Underwriter shall have received letters, dated, respectively, the date hereof and such Closing Date, of Ernst & Young LLP confirming that they are a registered public accounting firm and independent registered public accountants as required by the Act and the Rules and Regulations and substantially in the form of Schedule II hereto (except that in the letter dated on such Closing Date, the specified date referred to in paragraph 4 of such letter shall be a date no more than three days prior to such Closing Date).

(f) No Material Adverse Change. Subsequent to the execution and delivery of this Agreement, there shall not have occurred (i) any change, or any development or event involving a prospective change, in the condition (financial or otherwise), results of operations, business, properties or prospects of the Company and its subsidiaries taken as a whole which, in the judgment of the Underwriter, is material and adverse and makes it impractical or inadvisable to market the Securities; (ii) any downgrading in or withdrawal of the rating of any securities of the Company by any “nationally recognized statistical rating organization” (as defined for purposes of Section 3 of the Exchange Act), or any public announcement that any such organization has under surveillance or review its rating of any securities of the Company (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating); (iii) any change in U.S. or international financial, political or economic conditions or currency exchange rates or exchange controls the effect of which is such as to make it, in the judgment of the Underwriter, impractical to market or to enforce contracts for the sale of the Securities, whether in the primary market or in respect of dealings in the secondary market; (iv) any suspension or material limitation of trading in securities generally on the NYSE, or any setting of minimum or maximum prices for trading on such exchange; (v) or any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market; (vi) any banking moratorium declared by any U.S. federal, New York or Massachusetts state authorities; (vii) any major disruption of settlements of securities, payment, or clearance services in the United States or any other country where such securities are listed; or (viii) any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, any declaration of war by Congress or any other national or international calamity or emergency if, in the judgment of the Underwriter, the effect of any such attack, outbreak, escalation, act, declaration, calamity or emergency is such as to make it impractical or inadvisable to market the Securities or to enforce contracts for the sale of the Securities.

The Underwriter shall have received a certificate, dated the Closing Date, of an executive officer of the Company and a principal financial or accounting officer of the Company in which such officers shall state that: the representations and warranties of the Company in this Agreement are true and correct; the Company has complied with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date; no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or, to their knowledge, are contemplated by the Commission; and, subsequent to the date of the most recent financial statements in the General Disclosure Package and Final Prospectus, there has been no material adverse change in the condition (financial or otherwise), results of operations, business, properties or prospects of the Company and its subsidiaries taken as a whole except as set forth in the General Disclosure Package and Final Prospectus or as described in such certificate.

The Company will furnish the Underwriter with such conformed copies of such opinions, certificates, letters and documents as the Underwriter reasonably requires. The Underwriter may in its sole discretion waive compliance with any conditions to the obligations of the Underwriter hereunder.

8. Indemnification and Contribution. (a) Indemnification of the Underwriter. The Company will indemnify and hold harmless the Underwriter, its partners, members, directors, officers, employees, agents, affiliates and each person, if any, who controls the Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an “Indemnified Party”), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation 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 any material fact contained in any part of the Registration Statement, any Statutory Prospectus, the Final Prospectus, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d), or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred; 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 an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by the Underwriter specifically for use therein, it being understood and agreed that the only such information furnished by the Underwriter consists of the information described as such in subsection (b) below.

(b) Indemnification of Company. The Underwriter will indemnify and hold harmless the Company, each of its directors and each of its officers who signs a Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an “Underwriter Indemnified Party”), against any losses, claims, damages or liabilities to which such Underwriter Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation 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 any material fact contained in any part of the Registration Statement, any Statutory Prospectus, the Final Prospectus, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or the alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by the Underwriter specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Underwriter Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that the only such information furnished by the Underwriter consists of (i) the second sentence in the seventh paragraph of text under the caption “Underwriting” in the Final Prospectus, concerning market making and (ii) the ninth and tenth paragraphs of text under the caption “Underwriting” in the Final Prospectus, concerning short sales, stabilizing transactions and purchases to cover positions created by short sales.

(c) Actions against Parties; Notification. Promptly after receipt by an indemnified party under this Section 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 subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(d) Contribution. If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriter on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriter on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriter. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which the Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and the Underwriter set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of the Underwriter, the Company, the Trust or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Securities. If for any reason the Securities are not delivered by or on behalf of the Trust as provided herein, the Company will reimburse the Underwriter for all out-of-pocket expenses approved in writing by the Company, including fees and disbursements of counsel, reasonably incurred by the Underwriter in making preparations for the purchase, sale and delivery of the Securities not so delivered, but the Company shall then be under no further liability to the Underwriter except as provided in Sections 5(l) and 8 hereof; provided, however, that all parties shall only be responsible for their own out-of pocket expenses, including fees and disbursements of counsel, if any Securities are not delivered by or on behalf of the Trust as provided herein for any of the following reasons: (i) a suspension or material limitation in trading in securities generally on the NYSE, or any setting of minimum or maximum prices for trading on such exchange; (ii) a general moratorium on commercial banking activities declared by either Federal, New York or Massachusetts State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States; (iii) the outbreak or escalation of hostilities involving the United States or the declaration by the United States of a national emergency or war; or (iv) the occurrence of any other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere.

(d) Waiver.
