Ladies and Gentlemen:

Assured Guaranty Ltd., a Bermuda company (the “Unit Issuer”), subject to the terms and conditions stated herein, proposes to issue and sell to the several underwriters named in Schedule A (the “Underwriters”) an aggregate of 3,000,000 of its Equity Units (the “Equity Units”). In addition, the Unit Issuer has granted to the Underwriters an option to purchase up to an additional 450,000 Equity Units (the “Optional Securities”), as provided in Section 2 (the Equity Units and, if and to the extent such option is exercised, the Optional Securities are collectively called the “Securities”). ▇▇▇▇▇▇▇ Lynch, Pierce, ▇▇▇▇▇▇ & ▇▇▇▇▇ Incorporated (“MLPFS”) has agreed to act as a representative of the several Underwriters (in such capacity, the “Representative”) in connection with the offering and sale of the Securities.

In connection with the aforementioned issuance and sale, at the request of the Unit Issuer, the Unit Issuer and the Underwriters agree that up to 25% of the Equity Units and the Common Shares being issued in the Common Shares Offering (as such terms are defined below) (the “WLR Shares”) shall be reserved for sale by the Underwriters to WLR Recovery Fund IV, L.P., a shareholder of the Unit Issuer, or one of its affiliated funds (collectively “WLR”) as part of the distribution of the Securities by the Underwriters, subject to the terms of this Agreement, the Investment Agreement, dated as of February 28, 2008, by and between the Unit Issuer and WLR Recovery Fund IV, L.P., as amended by the First Amendment to Investment Agreement dated as of November 13, 2008 and the Second Amendment to investment agreement, dated as of June 10, 2009 (as so amended, the “Investment Agreement”), and all applicable laws, rules and regulations. To the extent that such WLR Shares are not confirmed for purchase by WLR by the end of the

Pre-Emptive Period (as defined in the Investment Agreement), such WLR Shares may be offered to the public as part of the public offering contemplated hereby.

Each Equity Unit has a stated amount of $50 (the “Stated Amount”) and initially consists of (i) a purchase contract (each, a “Purchase Contract”) under which the holder will agree to purchase, and the Unit Issuer will agree to sell, on June 1, 2012 (the “Purchase Contract Settlement Date”), subject to early settlement of such Purchase Contract pursuant to the provisions of the Purchase Contract and Pledge Agreement (the “Purchase Contract and Pledge Agreement”), to be dated as of the Closing Date (as defined below), among the Unit Issuer, The Bank of New York Mellon, as collateral agent, custodial agent and securities intermediary, and The Bank of New York Mellon, as purchase contract agent (the “Purchase Contract Agent”), for a price equal to the Stated Amount per Equity Unit, a number of common shares (the “Issuable Common Shares”) of the Unit Issuer, par value $0.01 per share (the “Common Shares”), determined pursuant to the terms of the Purchase Contract and Pledge Agreement and (ii) a 1/20, or 5.0%, undivided beneficial ownership interest in $1,000 principal amount of the 8 1/2% senior notes due June 1, 2014 (the “Notes”) of Assured Guaranty US Holdings Inc., a wholly owned subsidiary of the Unit Issuer (“AGUH” or the “Note Issuer” and, together with the Unit Issuer, the “Issuers”).

The Notes will be issued pursuant to an indenture (the “Base Indenture”), to be dated as of the Closing Date between the Note Issuer and The Bank of New York Mellon (formerly known as The Bank of New York), as trustee (the “Trustee”). Certain terms of the Notes will be established pursuant to a supplemental indenture (the “Supplemental Indenture”) in accordance with Article Nine of the Base Indenture (together with the Base Indenture, the “Indenture”).

Pursuant to the Indenture, the Unit Issuer has agreed to fully, irrevocably and unconditionally guarantee (the “Guarantees”), to each holder of the Notes and to the Trustee, (1) the full and punctual payment of principal of, premium, if any, interest and any Additional Amounts (as defined in the Indenture) in respect thereof on the Notes when due, whether at maturity, by acceleration, by redemption or otherwise, and all other monetary obligations of the Note Issuer under the Indenture and the Notes and (2) the full and punctual performance within applicable grace periods of all other obligations of the Note Issuer under the Indenture and the Notes.

A holder’s ownership interest in the Notes initially will be pledged to secure such holder’s obligation to purchase the Issuable Common Shares on the Purchase Contract Settlement Date, such pledge to be on the terms and conditions set forth in the Purchase Contract and Pledge Agreement.

The Purchase Contracts will be issued pursuant to the Purchase Contract and Pledge Agreement. The Purchase Contracts together with the related Notes (or upon the occurrence of a successful remarketing of the Notes prior to the Purchase Contract Settlement Date, the Treasury portfolio) are herein referred to as the “Corporate Units.”

A holder of Corporate Units, at its option, may, subject to the terms and conditions set forth in the Purchase Contract and Pledge Agreement, elect to create “Treasury Units” by substituting pledged U.S. treasury securities for any pledged ownership interests in the Notes. Unless otherwise indicated, the term “Equity Units” includes both Corporate Units and Treasury Units.

Pursuant to a remarketing agreement (the “Remarketing Agreement”), the form of which is attached to the Purchase Contract and Pledge Agreement, to be entered into among the Issuers, the Purchase Contract Agent and one or more nationally recognized investment banking firms to be selected by the Issuers, as the reset agent(s) and remarketing agent(s), the Notes will be remarketed, subject to certain terms and conditions set forth in the Remarketing Agreement.

The “Component Securities” means, collectively, the Purchase Contracts, the Notes, the Guarantees and the Issuable Common Shares.

The terms and rights of any particular issuance of Securities (including the Component Securities) shall be as specified in (i) the Indenture or (ii) the Purchase Contract and Pledge Agreement (each document listed in clauses (i) and (ii), together with the Remarketing Agreement, a “Securities Agreement” and collectively, the “Securities Agreements”).

The Unit Issuer is concurrently publicly offering its Common Shares (the “Common Shares Offering”) through the Representative and any other underwriters. The offering of the Securities is not contingent upon completion of the Common Shares Offering; the Common Shares Offering is not contingent upon the completion of the offering of the Securities; and the Common Shares are not being offered together with the Securities.

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

The Issuers hereby confirm their agreement with the Underwriters as follows:

SECTION 1. Representations and Warranties.

(a) The Issuers hereby represent, warrant and covenant to each Underwriter as follows:

i. Registration Statement and Prospectus. The Issuers have prepared and filed with the Securities and Exchange Commission (the “Commission”) an “automatic shelf registration statement” (as defined in Rule 405 under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (the “Securities Act”)) on Form S-3 (File No. 333-152892), which contains a base prospectus (the “Base Prospectus”), to be used in connection with the public offering and sale of the Securities. Such registration statement, as amended, including the financial statements, exhibits and schedules thereto, including any required information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430B under the Securities Act or the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”), is called the “Registration Statement.” Any preliminary prospectus supplement to the Base Prospectus that describes the Securities and the offering thereof and is used prior to filing of the final prospectus is called, together with the Base Prospectus, a “preliminary prospectus.” The term “Prospectus” shall mean the final prospectus supplement relating to the Securities, together with the Base Prospectus, that is first filed pursuant to Rule 424(b) under the Securities Act after the date and time that this Agreement is executed and delivered by the parties hereto (the “Execution Time”). Any reference herein to the Registration

Statement, any preliminary prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act; any reference to any amendment or supplement to any preliminary prospectus or the Prospectus shall be deemed to refer to and include any documents filed after the date of such preliminary prospectus or Prospectus, as the case may be, under the Exchange Act, and incorporated by reference in such preliminary prospectus or Prospectus, as the case may be; and any reference to any amendment to the Registration Statement shall be deemed to refer to and include any annual report of the Unit Issuer filed pursuant to Section 13(a) or 15(d) of the Exchange Act after the effective date of the Registration Statement that is incorporated by reference in the Registration Statement. All references in this Agreement to the Registration Statement, a preliminary prospectus, the Prospectus, or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the Commission pursuant to the Electronic Data Gathering, Analysis and Retrieval System (“▇▇▇▇▇”).

ii. Compliance with Registration Requirements. The Registration Statement has been declared effective by the Commission under the Securities Act. The Issuers have complied to the Commission’s satisfaction with all requests of the Commission for additional or supplemental information. No stop order suspending the effectiveness of the Registration Statement is in effect, the Commission has not issued any order or notice preventing or suspending the use of the Registration Statement, any preliminary prospectus or the Prospectus and no proceedings for such purpose have been instituted or are pending or, to the best knowledge of the Issuers, are contemplated or threatened by the Commission.

Each preliminary prospectus and the Prospectus when filed complied in all material respects with the Securities Act and the rules thereunder and, if filed by electronic transmission pursuant to ▇▇▇▇▇ (except as may be permitted by Regulation S-T under the Securities Act), was identical to the copy thereof delivered to the Underwriters for use in connection with the offer and sale of the Securities. Each of the Registration Statement and any post-effective amendment thereto, at the time it became effective and at the date hereof, complied and will comply in all material respects with the Securities Act and did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading. The Prospectus, as amended or supplemented, as of its date, at the date hereof, at the time of any filing pursuant to Rule 424(b) under the Securities Act, at the Closing Date (as defined herein) and at any Subsequent Closing Date (as defined herein), did not and will not contain 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. The representations and warranties set forth in the two immediately preceding sentences do not apply to statements in or omissions from the Registration Statement or any post-effective amendment thereto, or the Prospectus, or any amendments or supplements thereto, made in reliance upon and in conformity with information relating to any Underwriter furnished to the Issuers by any Underwriter through the Representative expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 7(b) hereof. There is no contract or other document required to be described in a preliminary prospectus or the Prospectus or to be filed as exhibits to the Registration Statement that has not been described or filed as required.

The documents incorporated by reference in a preliminary prospectus and the Prospectus, when they became effective or were filed with the Commission, as the case may be, conformed in all material respects to the requirements of the Securities Act or the Exchange Act, as applicable. Any further documents so filed and incorporated by reference in a preliminary prospectus or the Prospectus or any further amendment or supplement thereto, when such documents become effective or are filed with the Commission, as the case may be, will conform in all material respects to the requirements of the Securities Act or the Exchange Act, as applicable, and the rules and regulations of the Commission thereunder.

iii. Disclosure Package. The term “Disclosure Package” shall mean (i) the Base Prospectus, as amended or supplemented as of the Applicable Time, including any preliminary prospectus supplement, (ii) the issuer free writing prospectuses as defined in Rule 433 of the Securities Act (each, an “Issuer Free Writing Prospectus”), if any, identified in Schedule B hereto, and (iii) any other free writing prospectus that the parties hereto shall hereafter expressly agree in writing to treat as part of the Disclosure Package. The Issuers will prepare a final term sheet containing only a description of the Securities, in substantially the form attached hereto as Schedule C, 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”). The Final Term Sheet is an Issuer Free Writing Prospectus for purposes of this Agreement. As of 6:00 P.M. (Eastern time) on the date of this Agreement (the “Applicable Time”), the Disclosure Package did 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 Issuers by any Underwriter through the Representative expressly 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 7(b) hereof.

iv. The Issuer Not Ineligible Issuer. At the Execution Time, neither Issuer was and is an Ineligible Issuer (as defined in Rule 405 of the Securities Act), without taking account of any determination by the Commission pursuant to Rule 405 of the Securities Act that it is not necessary that either Issuer be considered an Ineligible Issuer.

v. Issuer Free Writing Prospectuses. Any Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the offering or until any earlier date that the Issuers notified or notify the Representative as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, a preliminary prospectus or the Prospectus. 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, a preliminary prospectus or the Prospectus, the Issuers have promptly notified or will promptly notify the Representative and have promptly amended or supplemented or will promptly amend or supplement, at their own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict. The foregoing two sentences do not apply to statements in or omissions from any Issuer Free Writing Prospectus based upon and in conformity with written information furnished to the Issuers by any Underwriter specifically through the Representative expressly for use therein, it being understood and agreed

that the only such information furnished by any Underwriter consists of the information described as such in Section 7(b) hereof.

vi. Distribution of Offering Material. The Issuers have not distributed and will not distribute, prior to the later of the last Subsequent Closing Date (as defined below) and the completion of the Underwriters’ distribution of the Securities, any offering material in connection with the offering and sale of the Securities other than a preliminary prospectus, the Prospectus, any Issuer Free Writing Prospectus reviewed and consented to by the Representative and included in Schedule B hereto or the Registration Statement. The Representative shall provide notice to the Issuers if the distribution of the Securities has not been completed on the date of Closing Date, and upon such later date as the distribution of the Securities has been completed.

vii. No Applicable Registration or Other Similar Rights. There are no persons with registration or other similar rights to have any equity or debt securities registered for sale under the Registration Statement or included in the offering contemplated by this Agreement, except for such rights as have been duly waived. No stockholder of the Unit Issuer or any other person has any preemptive right, right of first refusal or other similar right to subscribe for or purchase securities of the Unit Issuer under (a) the Memorandum of Association or the Bye-laws of the Unit Issuer or (b) any contract, agreement or instrument to which the Unit Issuer is a party, other than the rights of WLR Recovery Fund IV, L.P., a shareholder of the Unit Issuer, or one of its affiliated funds (collectively “WLR”) under the Investment Agreement, dated as of February 28, 2008, by and between the Unit Issuer and WLR Recovery Fund IV, L.P., as amended by the Amendment to Investment Agreement dated November 13, 2008.

The Issuers do not believe that (1) either the Unit Issuer or any of its subsidiaries (including the Note Issuer) currently should be, or upon the sale of the Securities herein contemplated should be, (A) treated as a “passive foreign investment company” as defined in Section 1297(a) of the Internal Revenue Code of 1986, as amended (the “Code”), (B) except for AGUH, AG Financial Products Inc., Assured Guaranty Corp., Assured Guaranty Overseas US Holdings Inc., Assured Guaranty Re Overseas Ltd., AG Intermediary Inc. and Assured Guaranty Mortgage Insurance Company, considered to be engaged in a trade or business within the United States for purposes of Section 864(b) of the Code or (C) except for Assured Guaranty Finance Overseas Ltd. , Assured Guaranty (UK) Services Ltd. and Assured Guaranty (UK) Ltd., characterized as resident, managed or controlled or carrying on a trade through a branch or agency in the United Kingdom or (2) any U.S. person who owns shares of the Unit Issuer directly or indirectly through foreign entities should be treated as owning (directly, indirectly through foreign entities or by attribution pursuant to Section 958(b) of the Code) 10 percent or more of the total voting power of the Unit Issuer or any of its non-U.S. subsidiaries.

xxvi. Related Person Insurance Income. Except as disclosed in the Disclosure Package and the Prospectus, Assured Guaranty Re Ltd. intends to operate in a manner that is intended to ensure that either (i) the related person insurance income of such company does not equal or exceed 20% of such company’s gross insurance income for any taxable year in the foreseeable future or (ii) at all times during each taxable year for the foreseeable future less than 20% of the voting power and less than 20% of the value of the shares of Assured Guaranty Re Ltd. is owned (directly or indirectly) by persons who are (directly or indirectly) insured (each, an “insured”) under any policy of insurance or reinsurance issued by Assured Guaranty Re Ltd. or related persons to any such insured.

xxvii. Accuracy of Statements. The statements set forth in the Disclosure Package and the Prospectus under the captions “Description of The Equity Units,” “Description of The Purchase Contracts,” “Certain Provisions of The Purchase Contract and Pledge Agreement,” “Description of The Notes,” “Description of Assured Guaranty Share Capital,” “Description of The Assured Guaranty US Holdings Debt Securities and Assured Guaranty Guarantee,” and “Description of Stock Purchase Contracts and Stock Purchase Units,” insofar as they purport to constitute a summary of the terms of the Securities, the Component Securities and the Securities Agreements, and under the captions “Material Tax Considerations” and “Description of The Acquisition” and in the Unit Issuer’s Annual Report on Form 10-K for the year ended December 31, 2008, under the captions “Part I—Item 1—Business—Regulation,” and “Part I—Item 3—Legal Proceedings,” insofar as they purport to describe the provisions of the laws and documents referred to therein, are true, accurate and complete in all material respects.

xxviii. No Price Stabilization or Manipulation. The Unit Issuer has not taken and will not take, directly or indirectly, any action designed to or that might be reasonably expected to cause or result in stabilization or manipulation of the price of the Common Shares to facilitate the sale or resale of the Securities. The Unit Issuer acknowledges that the Underwriters may engage in passive market making transactions in the Securities on the New York Stock Exchange in accordance with Regulation M under the Exchange Act.

xxix. Internal Controls and Procedures. The Unit Issuer maintains a system of internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) designed by, or under the supervision of, the Unit Issuer’s principal executive officer and principal financial officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. The Unit Issuer’s internal control over financial reporting was effective as of the end of the year ended December 31, 2008, and there have been no changes in the Unit Issuer’s internal control over financial reporting since such time and the Unit Issuer is not aware of any material weaknesses in its internal control over financial reporting.

xxx. No Material Action or Proceeding. Other than as set forth in the Disclosure Package and the Prospectus, there are no legal or governmental proceedings pending to which the Unit Issuer or any of its subsidiaries (including the Note Issuer) is a party or of which any property of the Unit Issuer or any of its subsidiaries (including the Note Issuer) is the subject which, if determined adversely to the Unit Issuer or any of its subsidiaries (including the Note Issuer), would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; and, to the best of the Issuers’ knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others.

xxxi. Not an “Investment Company.” Neither Issuer is and, after giving effect to the offering and sale of the Securities, will be an “investment company”, as such term is defined in the Investment Company Act of 1940, as amended (the “Investment Company Act”).

xxxii. No Stamp Duty, Transfer, Excise or Similar Tax. No Underwriter and no subsequent purchaser of the Securities is subject to any stamp duty, transfer, excise or similar tax imposed in Bermuda in connection with the issuance, offering or sale of the Securities to the Underwriters or to any subsequent purchaser.

xxxiii. Bermuda Exempted Companies. There are no currency exchange control laws or withholding taxes, in each case of Bermuda, that would be applicable to (1) the payment of interest or principal on the Securities by the Unit Issuer (other than as may apply to residents of Bermuda for Bermuda exchange control purposes) or (2) the payment of dividends, interest or principal by the any of the Unit Issuer’s subsidiaries to such subsidiary’s parent company. The Bermuda Monetary Authority has designated the Unit Issuer, Assured Guaranty Re Ltd. and Assured Guaranty Re Overseas Ltd. (Assured Guaranty Re Ltd. and Assured Guaranty Re Overseas Ltd. are collectively referred to as the “Bermuda Subsidiaries”) as non-resident for exchange control purposes. Each of the Unit Issuer and the Bermuda Subsidiaries are “exempted companies” under Bermuda law and have not (A) acquired and do not hold any land for its business in Bermuda, other than that held by way of lease or tenancy for terms of not more than 50 years, without the express authorization of the Bermuda Minister of Finance, (B) acquired and do not hold land by

None of the Unit Issuer or any of the Bermuda Subsidiaries has received notification from the Bermuda Monetary Authority or any other Bermuda governmental authority of proceedings relating to the modification or revocation of its designation as non-resident for exchange control purposes, its permission to issue and transfer the Securities, or its status as an “exempted company” under Bermuda law.

xxxiv. Independent Accountants of the Unit Issuer. PricewaterhouseCoopers LLP, who have expressed their opinion with respect to the financial statements and the related notes thereto of the Unit Issuer and its subsidiaries, are independent public accountants with respect to the Unit Issuer, as required by the Securities Act and the Exchange Act and the rules and regulations of the Commission thereunder.

xxxv. Preparation of the Financial Statements of the Unit Issuer. The financial statements and schedules of the Unit Issuer and its subsidiaries incorporated by reference in the Registration Statement, the Disclosure Package and the Prospectus present fairly in all material respects the financial condition, results of operations and cash flows of the entities purported to be shown thereby at the dates and for the periods indicated and have been prepared in accordance with United States generally accepted accounting principles applied on a consistent basis throughout the periods indicated and conform in all material respects with the rules and regulations adopted by the Commission under the Act; and the supporting schedules incorporated by reference in the Registration Statement, the Disclosure Package and the Prospectus present fairly in all materials respects the information required to be stated therein.

xxxvii. No Unlawful Contributions or Other Payments. Neither the Unit Issuer nor any of its subsidiaries (including the Note Issuer) nor, to the knowledge of the Unit Issuer, any director, officer, agent, employee or affiliate of the Unit Issuer or any of its subsidiaries (including the Note Issuer), acting in such capacities, has taken any action, directly or indirectly, that would result in a material violation by such persons of the FCPA (as defined below), including, without limitation, making use of the mails or any means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment, promise to pay or authorization of the payment of any money, or other property, gift, promise to give, or authorization of the giving of anything of value to any “foreign official” (as such term is defined in the FCPA) or any foreign political party or official thereof or any candidate for foreign political office, in contravention of the FCPA in any material respect, and the Unit Issuer, its subsidiaries (including the Note Issuer) and, to the knowledge of the Unit Issuer, its affiliates have conducted their businesses in compliance with the FCPA in all

material respects and have instituted and maintain policies and procedures designed to ensure, and which are reasonably expected to continue to ensure, continued compliance therewith. “FCPA” means the Foreign Corrupt Practices Act of 1977, as amended, and the rules and regulations thereunder.

xxxviii. No Conflict with Money Laundering Laws. The operations of the Unit Issuer and its subsidiaries (including the Note Issuer) are and have been conducted at all times in compliance in all material respects with applicable financial recordkeeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the money laundering statutes of all applicable jurisdictions, the rules and regulations thereunder and any related or similar rules, regulations or guidelines issued, administered or enforced by any governmental agency (collectively, the “Money Laundering Laws”) and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Unit Issuer or any of its subsidiaries (including the Note Issuer) with respect to the Money Laundering Laws is pending or, to the best knowledge of the Unit Issuer, threatened.

xxxix. No Conflict with OFAC Laws.

Any certificate signed by an officer of either Issuer and delivered to the Representative or to counsel for the Underwriters shall be deemed to be a representation and warranty by such Issuer to each Underwriter as to the matters set forth therein.

SECTION 2. Purchase, Sale and Delivery of the Securities.

(a) Purchase and Sale of the Equity Units. The Unit Issuer agrees to issue and sell to the several Underwriters the Equity Units upon the terms set forth herein. On the basis of the representations, warranties and agreements herein contained, and upon the terms but subject to the conditions herein set forth, the Underwriters agree, severally and not jointly, to purchase from the Unit Issuer the respective number of Equity Units set forth opposite their names on Schedule A. The purchase price per Equity Unit to be paid by the several Underwriters to the Unit Issuer shall be $48.50.

(b) The Closing Date. Delivery of certificates for the Equity Units to be purchased by the Underwriters and payment therefor shall be made at the offices of ▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP, ▇▇▇▇ ▇▇▇▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, at 10 A.M. New York City time on June 24, 2009 or such other later date not more than three business days after such date as the Representative shall designate by notice to the Unit Issuer (the time and date of such closing are called the “Closing Date”). Immediately following the Closing Date, the Unit Issuer shall cause its transfer agent to enter the transfers of Securities in the Unit Issuer’s register of members.

(c) The Optional Securities; the Subsequent Closing Date. In addition, on the basis of the representations, warranties and agreements herein contained, and upon the terms but subject to the conditions herein set forth, the Unit Issuer hereby grants an option to the several Underwriters to purchase, severally and not jointly, up to an aggregate of 450,000 Optional Securities from the Unit Issuer at the purchase price per Equity Unit to be paid by the Underwriters. The option granted hereunder may be exercised at any time and from time to time upon notice by the Representative to the Unit Issuer, which notice may be given at any time within 13 days from the date of this Agreement. Such notice shall set forth (i) the aggregate number of Optional Securities as to which the Underwriters are exercising the option, (ii) the names and denominations in which the certificates for the Optional Securities are to be registered and (iii) the time, date and place at which such certificates will be delivered (which time and date may be simultaneous with, but not earlier than, the Closing Date; and in such case the term “Closing Date” shall refer to the time and date of delivery of certificates for the Equity Units and the Optional Securities). Each time and date of delivery, if subsequent to the Closing Date, is called a “Subsequent Closing Date” and shall be determined by the Representative and shall not be earlier than three nor later than five full business days after delivery of such notice of exercise. If any Optional Securities are to be purchased, each Underwriter agrees, severally and not jointly, to purchase the number of Optional Securities (subject to such adjustments to eliminate fractional shares as the Representative may determine) that bears the same proportion to the total number of Optional Securities to be purchased as the number of Equity Units set forth on Schedule A opposite the name of such Underwriter bears to the total number of Equity Units.

(d) Public Offering of the Securities. The Representative hereby advises the Unit Issuer that the Underwriters intend to offer for sale to the public, as described in the Prospectus, their respective portions of the Securities as soon after this Agreement has been executed as the Representative, in its sole judgment, has determined is advisable and practicable.

(e) Payment for the Securities. Payment for the Securities shall be made on the Closing Date (and, if applicable, at any Subsequent Closing Date) by wire transfer of immediately available funds to the order of the Unit Issuer.

It is understood that the Representative has been authorized, for its own account and the accounts of the several Underwriters, to accept delivery of and receipt for, and make payment of the purchase price for, the Equity Units and any Optional Securities the Underwriters have agreed to purchase. MLPFS, individually and not as the Representative of the Underwriters, may (but shall not be obligated to) make payment for any Securities to be purchased by any Underwriter whose funds shall not have been received by the Representative by the Closing Date or any Subsequent Closing Date, as the case may be, for the account of such Underwriter, but any such payment shall not relieve such Underwriter from any of its obligations under this Agreement.

(f) Delivery of the Securities. The Securities to be purchased by the Underwriters hereunder, in definitive form and in such authorized denominations and registered in such names as the Underwriters may request, upon at least forty-eight hours’ prior notice to the Unit Issuer, shall be delivered together with instruments of transfer by or on behalf of the Unit Issuer to the Unit Issuer’s transfer agent and in turn to the Underwriters, through the facilities of The Depository Trust Company (the “DTC”), for the account of the Underwriters, against payment by or on behalf of the Underwriters of the purchase price therefor by wire transfer of Federal

(same-day) funds to the account specified by the Issuer to the Underwriters at least forty-eight hours in advance. The Unit Issuer will cause the certificates representing the Securities to be made available for checking and packaging at least twenty-four hours prior to the Closing Date with respect thereto at the office of DTC or its designated custodian.

(g) Delivery of Prospectuses to the Underwriters. Not later than 10:00 a.m. on the second business day following the date the Securities are first released by the Underwriters for sale to the public, the Unit Issuer shall deliver or cause to be delivered copies of the Prospectus in such quantities and at such places as the Representative shall request.

SECTION 3. Covenants of the Issuers.

The Issuers covenant and agree with each Underwriter as follows:

(i) Review of Proposed Amendments and Supplements. During the period beginning at the Applicable Time and ending on the later of the Closing Date or such date, as in the opinion of counsel for the Underwriters, the Prospectus is no longer required by law to be delivered in connection with sales by an Underwriter or a dealer, including in circumstances where such requirement may be satisfied pursuant to Rule 172 under the Securities Act (the “Prospectus Delivery Period”), prior to amending or supplementing the Registration Statement, the Disclosure Package or the Prospectus (including any amendment or supplement through incorporation by reference of any report filed under the Exchange Act), the Issuers shall furnish to the Representative for review a copy of each such proposed amendment or supplement, and the Issuers shall not file or use any such proposed amendment or supplement to which the Representative reasonably objects. The Representative shall provide notice to the Issuers if the Prospectus Delivery Period has not ended on the date of the Closing Date, and upon such later date as the Prospectus Delivery Period has ended.

(ii) Securities Act Compliance. After the date of this Agreement, the Issuers shall promptly advise the Representative in writing (i) when the Registration Statement, if not effective at the Execution Time, shall have become effective, (ii) of the receipt of any comments of, or requests for additional or supplemental information from, the Commission, (iii) of the time and date of any filing of any post-effective amendment to the Registration Statement or any amendment or supplement to any preliminary prospectus or the Prospectus, (iv) of the time and date that any post-effective amendment to the Registration Statement becomes effective and (v) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order or notice preventing or suspending the use of the Registration Statement, any preliminary prospectus or the Prospectus, or of any proceedings to remove, suspend or terminate from listing or quotation the Common Shares from any securities exchange upon which it is listed for trading or included or designated for quotation, or of the threatening or initiation of any proceedings for any of such purposes. The Issuers shall use their best efforts to prevent the issuance of any such stop order or prevention or suspension of such use. If the Commission shall enter any such stop order or order or notice of prevention or suspension at any time, the Issuers will use their best efforts to obtain the lifting of such order at the earliest possible moment, or will file a new registration statement and use their best efforts to have such new registration statement declared effective as soon as practicable. Additionally, the Issuers agree that they shall comply with the provisions of Rules 424(b) and 430B, as applicable, under the Securities Act, including

with respect to the timely filing of documents thereunder, and will use their reasonable efforts to confirm that any filings made by the Issuers under such Rule 424(b) were received in a timely manner by the Commission.

(iii) Exchange Act Compliance. The Issuers, during the Prospectus Delivery Period, will file all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act.

(iv) Amendments and Supplements to the Registration Statement, Prospectus and Other Securities Act Matters. If, during the Prospectus Delivery Period, any event or development shall occur or condition exist as a result of which the Disclosure Package or the Prospectus as then amended or supplemented would include 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 or then prevailing, as the case may be, not misleading, or if it shall be necessary to amend or supplement the Disclosure Package or the Prospectus, or to file under the Exchange Act any document incorporated by reference in the Disclosure Package or the Prospectus, in order to make the statements therein, in the light of the circumstances under which they were made or then prevailing, as the case may be, not misleading, or if in the opinion of the Representative it is otherwise necessary to amend or supplement the Registration Statement, the Disclosure Package or the Prospectus, or to file under the Exchange Act any document incorporated by reference in the Disclosure Package or the Prospectus, or to file a new registration statement containing the Prospectus, in order to comply with law, including in connection with the delivery of the Prospectus, the Issuers agree to (i) notify the Representative of any such event or condition and (ii) promptly prepare (subject to Section 3(i) hereof), file with the Commission (and use their best efforts to have any amendment to the Registration Statement or any new registration statement to be declared effective) and furnish at their own expense to the Underwriters and to dealers, amendments or supplements to the Registration Statement, the Disclosure Package or the Prospectus, or any new registration statement, necessary in order to make the statements in the Disclosure Package or the Prospectus as so amended or supplemented, in the light of the circumstances under which they were made or then prevailing, as the case may be, not misleading or so that the Registration Statement, the Disclosure Package or the Prospectus, as amended or supplemented, will comply with law.

(v) Permitted Free Writing Prospectuses. The Issuers represent that they have not made, and agree that, unless they obtain the prior written consent of the Representative, they will not make, and each Underwriter represents that it has not made, and agrees that, unless it obtains the prior written consent of each Issuer, it will not make, in each case, any offer relating to the Securities that constitutes or would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 of the Securities Act) required to be filed by the Issuers with the Commission or retained by the Issuers under Rule 433 of the Securities Act; provided that the prior written consent of the Representative hereto shall be deemed to have been given in respect of the Issuer Free Writing Prospectuses included in Schedule B hereto. Any such free writing prospectus consented to by the Representative is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Issuers agree that (i) they have treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, and (ii) have complied and will comply, as the case may be, with the requirements of Rules 164 and 433 of the Securities Act applicable to any Permitted Free Writing

Prospectus, including in respect of timely filing with the Commission, legending and record keeping. The Issuers consent to the use by the Underwriters of a free writing prospectus that (a) is not an Issuer Free Writing Prospectus, and (b) contains only (i) information describing the price of the Securities or their offering or (ii) information permitted by Rule 134 under the Securities Act.

(vi) Copies of the Disclosure Package and the Prospectus. The Issuers agree to furnish the Representative, without charge, during the Prospectus Delivery Period, as many copies of the Disclosure Package and the Prospectus and any amendments and supplements thereto (including any documents incorporated or deemed incorporated by reference therein) as the Representative may request.

(vii) Copies of the Registration Statement. The Issuers will furnish to the Representative and counsel for the Underwriters signed copies of the Registration Statement (including exhibits thereto).

(viii) Blue Sky Compliance. The Issuers shall cooperate with the Representative and counsel for the Underwriters to qualify or register the Securities for sale under (or obtain exemptions from the application of) the state securities or blue sky laws or Canadian provincial Securities laws or other foreign laws of those jurisdictions designated by the Representative, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Securities. Neither Issuer shall be required to qualify as a foreign corporation or to take any action that would subject it to general service of process in any such jurisdiction where it is not presently qualified or where it would be subject to taxation as a foreign corporation, other than those arising out of the offering or sale of the Securities in any jurisdiction where it is not now so subject. The Issuers will advise the Representative promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Securities for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, the Issuers shall use their best efforts to obtain the withdrawal thereof at the earliest possible moment.

(ix) Use of Proceeds. The Issuers shall apply the net proceeds from the sale of the Securities sold by it in the manner described under the caption “Use of Proceeds” in the Disclosure Package and the Prospectus.

(xi) Remarketing Agreement. On or prior to the date that is 30 days prior to the first day of the Applicable Remarketing Period (as defined in the Purchase Contract and Pledge Agreement), the Issuers shall have entered into, and shall use their commercially reasonable efforts to have the Purchase Contract Agent enter into, the Remarketing Agreement.

(xii) Earnings Statement. As soon as practicable, the Unit Issuer will make generally available to its security holders and to the Representative an earnings statement (which need not be audited) covering the twelve-month period beginning with the first fiscal quarter of the Unit Issuer

ending after the effective date of the Registration Statement that satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 under the Securities Act.

(xiii) Restriction on Sale of Certain Securities. During the period commencing on the date hereof and ending on the 90th day following the date of the Prospectus, the Unit Issuer will not, without the prior written consent of the Representative (which consent may be withheld at the sole discretion of the Representative), directly or indirectly, sell, offer, contract or grant any option to sell, pledge, transfer or establish an open “put equivalent position” or liquidate or decrease a “call equivalent position” within the meaning of Rule 16a-1(h) under the Exchange Act, or otherwise dispose of or transfer (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition of), or announce the offering of, or file any registration statement under the Securities Act in respect of, any Common Shares or securities that are convertible into or exchangeable for Common Shares (other than the Securities, the Common Shares issued in the Common Shares Offering, and the issuance of awards pursuant to employee benefit plans outstanding as of the date hereof and issuances of Common Shares upon exercise of any such awards); provided that the foregoing shall not prohibit the Unit Issuer from (i) complying with the registration rights under the Investment Agreement, and (ii) issuing up to 44,567,901 Common Shares to Dexia Holdings, Inc. under the SPA and filing a registration statement on Form S-3 to register such Common Shares pursuant to Section 6.18 of the SPA.

(xv) No Manipulation of Price. The Unit Issuer will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, under the Exchange Act or otherwise, the stabilization or manipulation of the price of any securities of the Unit Issuer to facilitate the sale or resale of the Securities.

The Representative, on behalf of the several Underwriters, may, in its sole discretion, waive in writing the performance by either Issuer of any one or more of the foregoing covenants or extend the time for their performance.

(iii) there shall not have occurred any downgrading, nor shall any notice have been given of any intended or potential downgrading or of any review for a possible change that does not indicate the direction of the possible change, in the rating accorded any securities of or guaranteed by the Unit Issuer or any of its subsidiaries by any “nationally recognized statistical rating organization” as such term is defined for purposes of Rule 436(g)(2) under the Securities Act.

On or before the Closing Date and any Subsequent Closing Date, the Representative and counsel for the Underwriters shall have received such information, documents and opinions as they may reasonably require for the purposes of enabling them to pass upon the issuance and sale of the Securities as contemplated herein, or in order to evidence the accuracy of any of the representations and warranties, or the satisfaction of any of the conditions or agreements, herein contained.

If any condition specified in this Section 5 is not satisfied when and as required to be satisfied, this Agreement may be terminated by the Representative by notice to the Issuers at any time on or prior to the Closing Date and, with respect to the Optional Securities, at any time prior to the applicable Subsequent Closing Date, which termination shall be without liability on the part of any party to any other party, except that Section 4, Section 6, Section 7, Section 8 and Section 17 shall at all times be effective and shall survive such termination.

SECTION 6. Reimbursement of Underwriters’ Expenses. If this Agreement is terminated by the Underwriters pursuant to Section 5 or Section 10, or if the sale to the Underwriters of the Securities on the Closing Date or any Subsequent Closing Date is not consummated because of any refusal, inability or failure on the part of either Issuer to perform any agreement herein or to comply with any provision hereof, the Issuers agree to reimburse the Representative and the other Underwriters (or such Underwriters as have terminated this Agreement with respect to themselves), severally, upon demand for all out-of-pocket expenses that shall have been reasonably incurred by the Representative and the Underwriters in connection with the proposed purchase and the offering and sale of the Securities, including but not limited to fees and disbursements of counsel, printing expenses, travel expenses, postage, facsimile and telephone charges.

SECTION 7. Indemnification.

(a) Indemnification of the Underwriters. The Issuers jointly and severally agree to indemnify and hold harmless each Underwriter, its directors, officers, employees and agents, and each person, if any, who controls any Underwriter within the meaning of the Securities Act and the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Underwriter or such director, officer, employee, agent or controlling person may become subject, insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based (i) upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, including any information deemed to be a part thereof pursuant to Rule 430A, Rule 430B or Rule

430C under the Securities Act, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) upon any untrue statement or alleged untrue statement of a material fact contained in any Issuer Free Writing Prospectus, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto), or any “road show” (as defined in Rule 433 under the Securities Act) not constituting an Issuer Free Writing Prospectus (a “Non-IFWP Road Show”) or the omission or alleged omission therefrom of a material fact, in each case, necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, and to reimburse each Underwriter, its officers, directors, employees, agents and each such controlling person for any and all expenses (including the fees and disbursements of counsel chosen by the Representative) as such expenses are reasonably incurred by such Underwriter, or its officers, directors, employees, agents or such controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Issuers by the Underwriters through the Representative expressly for use in the Registration Statement, any Issuer Free Writing Prospectus, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto).

(b) Indemnification of the Issuers, their Directors and Officers. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Issuers, each of their directors, each of their officers who signed the Registration Statement and each person, if any, who controls either Issuer within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Issuers or any such director, officer or controlling person may become subject, insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based (i) upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) upon any untrue statement or alleged untrue statement of a material fact contained in any Issuer Free Writing Prospectus, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto), or any Non-IFWP Road Show, or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, and only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Issuer Free Writing Prospectus, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) or any Non-IFWP Road Show, in reliance upon and in conformity with written information furnished to the Issuers by the Representative expressly for use therein; and to reimburse the Issuers or any such director, officer or controlling person for any legal and other expense reasonably incurred by the Issuers or any such director, officer or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The Issuers hereby acknowledge that the only information that the Underwriters have furnished to the Issuers expressly for use in the Registration Statement, any Issuer Free Writing Prospectus, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) or any

▇▇

▇▇▇-▇▇▇▇ ▇▇▇▇ Show are the statements set forth in the third paragraph, the fifth paragraph and the second and third sentences of the seventh paragraph under the caption “Underwriting” in the Prospectus. The indemnity agreement set forth in this Section 7(b) shall be in addition to any liabilities that each Underwriter may otherwise have.

(c) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 7, notify the indemnifying party in writing of the commencement thereof; but the failure to so 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 liability other than the indemnification obligation provided in paragraph (a) or (b) above. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel satisfactory to such indemnified party; provided, however, such indemnified party shall have the right to employ its own counsel in any such action and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party, unless: (i) the employment of such counsel has been specifically authorized by the indemnifying party; (ii) the indemnifying party has failed promptly to assume the defense and employ counsel reasonably satisfactory to the indemnified party; or (iii) the named parties to any such action (including any impleaded parties) include both such indemnified party and the indemnifying party or any affiliate of the indemnifying party, and such indemnified party shall have reasonably concluded that either (x) there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party or such affiliate of the indemnifying party or (y) a conflict may exist between such indemnified party and the indemnifying party or such affiliate of the indemnifying party (it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to a single firm of local counsel) for all such indemnified parties, which firm shall be designated in writing by the Underwriters and that all such reasonable fees and expenses shall be reimbursed as they are incurred).

(d) Settlements. The indemnifying party under this Section 7 shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 7(c) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party

in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding 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 any indemnified party.

SECTION 8. Contribution. If the indemnification provided for in Section 7 is for any reason unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuers, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement 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 Issuers, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Issuers, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Issuers, and the total underwriting discount received by the Underwriters, in each case as set forth on the front cover of the Prospectus bear to the aggregate initial public offering price of the Securities as set forth on such cover. The relative fault of the Issuers, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Issuers, on the one hand, or the Underwriters, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 7(c), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 7(c) with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 8; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 7(c) for purposes of indemnification.

The Issuers and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 8.

Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the underwriting commissions received by such Underwriter in connection with the Securities underwritten by it and distributed to the public. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 8 are several, and not joint, in proportion to their respective underwriting commitments as set forth opposite their names in Schedule A. For purposes of this Section 8, each director, officer, employee and agent of an Underwriter and each person, if any, who controls an Underwriter within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of either Issuer, each officer of either Issuer who signed the Registration Statement and each person, if any, who controls either Issuer within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Issuers.

SECTION 9. Default of One or More of the Several Underwriters. If, on the Closing Date or a Subsequent Closing Date, as the case may be, any one or more of the several Underwriters shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on such date, and the aggregate number of Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase does not exceed 10% of the aggregate number of the Securities to be purchased on such date, the other Underwriters shall be obligated, severally, in the proportions that the number of Equity Units set forth opposite their respective names on Schedule A bears to the aggregate number of Equity Units set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as may be specified by the Representative with the consent of the non-defaulting Underwriters, to purchase the Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the Closing Date or a Subsequent Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Securities and the aggregate number of Securities with respect to which such default occurs exceeds 10% of the aggregate number of Securities to be purchased on such date, and arrangements satisfactory to the Representative and the Issuers for the purchase of such Securities are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Section 4, Section 6, Section 7 and Section 8 shall at all times be effective and shall survive such termination. In any such case either the Representative or the Issuers shall have the right to postpone the Closing Date or a Subsequent Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Registration Statement and the Prospectus or any other documents or arrangements may be effected.

As used in this Agreement, the term “Underwriter” shall be deemed to include any person substituted for a defaulting Underwriter under this Section 9. Any action taken under this Section 9 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

SECTION 10. Termination of this Agreement. Prior to the Closing Date and, with respect to the Optional Securities, any Subsequent Closing Date, this Agreement may be terminated by the Representative by notice given to the Issuers if at any time (i) trading or quotation in any of the Unit Issuer’s securities shall have been suspended or limited by the Commission or by the New York Stock Exchange, or trading in securities generally on the New York Stock Exchange shall

have been suspended or limited, or minimum or maximum prices shall have been generally established on any of such stock exchanges by the Commission or the FINRA; (ii) a general banking moratorium shall have been declared by federal or New York authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States has occurred; or (iii) there shall have occurred any outbreak or escalation of national or international hostilities any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, as in the judgment of the Representative is material and adverse and makes it impracticable or inadvisable to market the Securities in the manner and on the terms described in the Prospectus or to enforce contracts for the sale of securities. Any termination pursuant to this Section 10 shall be without liability on the part of (a) the Issuers to any Underwriter, except that the Issuers shall be obligated to reimburse the expenses of the Underwriter pursuant to Sections 4 and 6 hereof or (b) any Underwriter to the Issuers.

SECTION 11. No Advisory or Fiduciary Responsibility. The Issuers acknowledge and agree that (i) the purchase of the Securities by the Underwriters pursuant to this Agreement is an arm’s-length commercial transaction between the Issuers and the Underwriters, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Issuers, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Issuers with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Issuers on other matters) or any other obligation to the Issuers except the obligations expressly set forth in this Agreement, (iv) the Issuers have consulted their own legal and financial advisors to the extent they deemed appropriate and (v) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Issuers have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate. The Issuers agree that they will not claim that any Underwriter has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Issuers, in connection with such transaction or the process leading thereto.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between either Issuer and the several Underwriters, or any of them, with respect to the subject matter hereof.

SECTION 12. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of the Issuers, of their officers and of the several Underwriters set forth in or made pursuant to this Agreement (i) will remain operative and in full force and effect, regardless of any (A) investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the officers or employees of any Underwriter or any person controlling such Underwriter, or the Issuers, the officers or employees of the Issuers, or any person controlling either Issuer, as the case may be or (B) acceptance of the Securities and payment for them hereunder and (ii) will survive delivery of and payment for the Securities sold hereunder and any termination of this Agreement.

SECTION 16. Governing Law Provisions. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE.

(a) Consent to Jurisdicion. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) may be instituted in the federal courts of the United States of America located in the City and County of New York, Borough of Manhattan, or the courts of the State of New York in each case located in the City and County of New York, Borough of Manhattan (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court (a “Related Judgment”), as to which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court. The

parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum. The Unit Issuer has irrevocably appointed Assured Guaranty US Holdings Inc., ▇▇▇▇ ▇▇▇▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇ as its agent to receive service of process or other legal summons for purposes of any such suit, action or proceeding that may be instituted in any state or federal court in the City and County of New York.

(b) Waiver of Immunity. With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the Specified Courts, and with respect to any Related Judgment, each party waives any such immunity in the Specified Courts or any other court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or Related Judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

SECTION 17. General Provisions. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The Section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

interpolation between the number of shares set forth for the higher and lower share price amounts and the earlier and later effective dates, as applicable, based on a 365-day year.

· If the share price is greater than $100.00 per share (subject to adjustment), the fundamental change early settlement rate will be the minimum settlement rate.

· If the share price is less than $6.00 per share (subject to adjustment), the fundamental change early settlement rate will be the maximum settlement rate.

(x) the Notes have been duly authorized, executed and delivered by the Note Issuer and, when duly authenticated by the Trustee in accordance with the terms of the Indenture and delivered to and paid for by the Underwriters in accordance with the terms of this Agreement, will constitute legal, valid and binding obligations of the Note Issuer, entitled to the benefits of the Indenture and enforceable against the Note Issuer in accordance with their terms, except to the

EXHIBIT B

[Form of Opinion of Bermuda Counsel for the Unit Issuer]

(i) the Unit Issuer is duly incorporated and existing under the laws of Bermuda in good standing (meaning solely that it has not failed to make any filing with any Bermuda governmental authority or to pay any Bermuda government fee or tax which would make it liable to be struck off the Register of Companies and thereby cease to exist under the laws of Bermuda);

(vii) each of the Bermuda Subsidiaries is duly incorporated and existing under the laws of Bermuda in good standing (meaning solely that it has not failed to make any filing with any Bermuda governmental authority or to pay any Bermuda government fee or tax which would make it liable to be struck off the Register of Companies and thereby cease to exist under the laws of

Bermuda) and has the necessary corporate power and authority to conduct its business as described in the Disclosure Package and the Prospectus;

(viii) the Unit Issuer has taken all corporate action required to authorise its execution, delivery and performance of the Transaction Documents. Each of this Agreement, the Indenture, the Remarketing Agreement, and the Purchase Contract and Pledge Agreement has been duly authorized and (except for the Remarketing Agreement) executed by or on behalf of the Unit Issuer, and, when delivered, constitutes the valid and binding obligation of the Unit Issuer, enforceable against the Unit Issuer in accordance with the terms thereof, and the Securities, the Guarantees and the Purchase Contracts have been duly authorized, executed, issued, and delivered by the Unit Issuer.

(x) based solely upon a review of copies of the Certificates of Registration issued to each of the Bermuda Subsidiaries by the Bermuda Monetary Authority pursuant to the Insurance ▇▇▇ ▇▇▇▇ of Bermuda, (the “Insurance Act”) and the Certificates of Compliance issued by the Bermuda Monetary Authority and the Registrar of Companies in Bermuda, each of the Bermuda Subsidiaries is registered in Bermuda under the Insurance Act to carry on long-term business, Assured Guaranty Re Ltd. (“AG Re”) is registered to carry on general business as a Class 3B insurer and Assured Guaranty Re Overseas Ltd. (“AGRO”) is registered to carry on general business as a Class 3A insurer in accordance with the provisions of the Insurance Act and the conditions attached to their respective registration licenses;

(xi) each of the Unit Issuer and the Bermuda Subsidiaries has been designated as non-resident of Bermuda for the purposes of the Exchange Control Act, 1972 and, as such, are free to acquire, hold, transfer and sell foreign currency (including the payment of dividends or other distributions) and securities without restriction;

(xii) based solely upon a review of the copy of the register of members of AG Re on a specified date, certified by the Secretary of AG Re on as specified date, the issued share capital of AG Re consists of 1,377,587 common shares par value U.S.$1.00 each (the “AG Re Shareholding”) each of which is validly issued, fully paid and non-assessable (which term when used herein means that no further sums are required to be paid by the holders thereof in connection with the issue thereof) and the Unit Issuer is the registered holder of the AG Re Shareholding;

(xiii) based solely upon a review of the copy of the register of members of AGRO on a specified date, certified by the Secretary of AGRO on a specified date, the issued share capital of AGRO consists of 1,000,000 common shares par value U.S.$1.00 each (the “AGRO Shareholding”) each of which is validly issued, fully paid and non-assessable (which term when used herein means that no further sums are required to be paid by the holders thereof in connection

with the issue thereof) and Assured Guaranty Overseas US Holdings, Inc. is the registered holder of the AGRO Shareholding;

(xiv) the statements set forth in the Disclosure Package and the Prospectus under the captions “Description of Assured Guaranty Share Capital” and “Enforceability of Civil Liabilities Under United States Federal Securities Laws and Other Matters” and in the Disclosure Package and the Prospectus, to the extent they constitute statements of Bermuda law, are accurate in all material respects;

(xv) the discussion contained in the Unit Issuer’s Annual Report on Form 10-K for the year ended December 31, 2008, under the captions “Part 1 — Item 1 — Business — Regulation — Bermuda”, “Part 1 — Item 1 — Business — Tax Matters — Taxation of Assured Guaranty and Subsidiaries — Bermuda” and “Part 1 — Item 1 — Business — Taxation of Shareholders — Bermuda Taxation,” and in the Disclosure Package and the Prospectus under the caption “Material Tax Considerations—Bermuda Tax Consequences,” and in the Registration Statement under the caption “Item 15 — Indemnification of Directors and Officers”, to the extent that they constitute a statement of the Bermuda law are accurate in all material respects;

(xvi) the Unit Issuer, AG Re and AGRO have received an assurance from the Minister of Finance under The Exempted Undertakings Tax Protection Act 1966 in Bermuda that in the event of there being enacted in Bermuda any legislation imposing tax computed on profits or income or computed on any capital asset, gain or appreciation, or any tax in the nature of estate duty or inheritance tax, then the imposition of any such tax shall not be applicable to the Unit Issuer, AG Re and AGRO or any of their operations or shares, debentures or other obligations of the Unit Issuer, AG Re and AGRO, until 28 March 2016 (subject to certain provisos expressed in such assurance);

(xvii) the consummation of the transactions contemplated by the Transaction Documents (including but not limited to any actions taken pursuant to the indemnification and contribution provisions contained in the Transaction Documents) will not, subject to compliance with Section 39A(2A) of the Companies ▇▇▇ ▇▇▇▇, constitute unlawful financial assistance by the Unit Issuer under Bermuda law;

(xviii) it is not necessary or desirable to ensure the enforceability in Bermuda of each Transaction Document that it be registered in any register kept by, or filed with, any governmental authority or regulatory body in Bermuda. However, to the extent that any Transaction Document creates a charge over assets of the Unit Issuer, it may be desirable to ensure the priority in Bermuda of the charge that it be registered in the Register of Charges in accordance with Section 55 of the Companies ▇▇▇ ▇▇▇▇. On registration, to the extent that Bermuda law governs the priority of a charge, such charge will have priority in Bermuda over any unregistered charges created, and over any subsequently registered charges, in respect of the assets which are the subject of the charge. A registration fee of $541 will be payable in respect of the registration. While there is no exhaustive definition of a charge under Bermuda law, a charge includes any interest created in property by way of security (including any mortgage, assignment, pledge, lien or hypothecation). However, as the Transaction Documents are governed by the laws of the State of New York (“New York Laws”), the question of whether they create such an interest in property would be determined under the New York Laws;

(xix) the Transaction Documents and the instruments of transfer transferring the Securities will not be subject to ad valorem stamp duty in Bermuda;

(xx) No stockholder of the Unit Issuer or any other person has any preemptive right, right of first refusal or other similar right to subscribe for or purchase securities of the Unit Issuer arising by operation of the Memorandum of Association or Bye-Laws of the Unit Issuer or the law of the Islands of Bermuda;

(xxi) based solely upon a search of the Cause Book of the Supreme Court of Bermuda conducted at a specified time and date (which would not reveal details of proceedings which have been filed but not actually entered in the Cause Book at the time of our search), there are no judgments against the Unit Issuer or the Bermuda Subsidiaries, nor any legal or governmental proceedings pending in Bermuda to which the Unit Issuer or the Bermuda Subsidiaries is subject;

(xxii) based solely on a search of the public records in respect of the Unit Issuer and the Bermuda Subsidiaries maintained at the offices of the Registrar of Companies at a specified time and date (which would not reveal details of matters which have not been lodged for registration or have been lodged for registration but not actually registered at the time of our search) and a search of the Cause Book of the Supreme Court of Bermuda conducted at a specified time and date (which would not reveal details of proceedings which have been filed but not actually entered in the Cause Book at the time of our search), no steps have been, or are being, taken in Bermuda for the appointment of a receiver or liquidator to, or for the winding-up, dissolution, reconstruction or reorganisation of, the Unit Issuer or the Bermuda Subsidiaries, though it should be noted that the public files maintained by the Registrar of Companies do not reveal whether a winding-up petition or application to the Court for the appointment of a receiver has been presented and entries in the Cause Book may not specify the nature of the relevant proceedings;

(xxiii) the choice of New York laws as the governing law of each Transaction Document is a valid choice of law and would be recognised and given effect to in any action brought before a court of competent jurisdiction in Bermuda, except for those laws (i) which such court considers to be procedural in nature, (ii) which are revenue or penal laws or (iii) the application of which would be inconsistent with public policy, as such term is interpreted under the laws of Bermuda. The submission in each Transaction Document to the non-exclusive jurisdiction of the New York Courts is valid and binding upon the Unit Issuer; and

(xxiv) the courts of Bermuda would recognise as a valid judgment, a final and conclusive judgment in personam obtained in the New York Courts against the Unit Issuer based upon any Transaction Document under which a sum of money is payable (other than a sum of money payable in respect of multiple damages, taxes or other charges of a like nature or in respect of a fine or other penalty) and would give a judgment based thereon provided that (a) such courts had proper jurisdiction over the parties subject to such judgment, (b) such courts did not contravene the rules of natural justice of Bermuda, (c) such judgment was not obtained by fraud, (d) the enforcement of the judgment would not be contrary to the public policy of Bermuda, (e) no new admissible evidence relevant to the action is submitted prior to the rendering of the judgment by the courts of Bermuda and (f) there is due compliance with the correct procedures under the laws of Bermuda.
