Exhibit 1.2

SI Financial Group, Inc., a federal stock holding company (the “Company”), SI Bancorp, MHC, a federal mutual holding company (the “MHC”), and Savings Institute Bank and Trust Company, a federal savings bank (the “Bank”), hereby confirm their agreement with Sandler O’Neill & Partners, L.P. (“Sandler O’Neill” or the “Agent”) with respect to the offer and sale by the Company of up to 3,910,000 shares (subject to increase up to 4,496,500 shares in the event of an oversubscription) of the Company’s common stock, par value $.01 per share (the “Common Stock”). The shares of Common Stock to be sold by the Company in the Offerings (as defined below) are hereinafter called the “Securities.” In addition, as described herein, the Company expects to contribute shares of common stock equal to 2% of the shares of Common Stock issued in the Offerings to SI Financial Group Foundation, Inc., a charitable foundation (the “Foundation”), such shares hereinafter being referred to as the “Foundation Shares.”

The Securities are being offered for sale and the Foundation Shares are being contributed in accordance with the Plan of Reorganization and Minority Stock Issuance, as amended and restated, adopted by the Organizers of the Company and the Boards of Directors of MHC and the Bank, which provides for a stock offering, in compliance with regulations of the Office of Thrift Supervision (the “OTS”), of up to 49.9% of the Common Stock of the Company. The MHC will be required to own at least a majority of the Common Stock following consummation of the Offerings and the contribution of shares of Common Stock to the Foundation.

Pursuant to the Plan (as defined in Section (a)(ii) hereof), the Company will offer to certain depositors of the Bank and to the Bank’s tax qualified employee benefit plans, including the Bank’s employee stock ownership plan (the “ESOP”) (collectively, the “Employee Plans”), rights to subscribe for the Securities in a subscription offering (the “Subscription Offering”). To the extent Securities are not subscribed for in the Subscription Offering, such Securities may be offered to other persons in a community offering (the “Community Offering”), with preference given first to certain borrowers of the Bank, second to natural persons and trusts of natural persons residing in Hartford, New London, Tolland and Windham Counties, Connecticut, and third to other persons to whom the Company delivers a Prospectus (as hereinafter defined). The Community Offering, which together with the Subscription Offering, as each may be extended or reopened from time to time, are herein referred to as the “Subscription and Community Offerings,” may be commenced concurrently with, during or after, the Subscription Offering. It is currently anticipated by the Bank and the Company that any Securities not subscribed for in the Subscription and Community Offerings will be offered, subject to Section 2 hereof, in a syndicated community offering (the “Syndicated Community Offering”). The Subscription and Community Offerings and the Syndicated Community Offering are hereinafter referred to collectively as the “Offerings.” The Securities may be offered to the general public in a public offering (the “Public Offering”) in lieu of or subsequent to the Syndicated Community Offering. If there is a Public Offering, the Public Offering will be governed by a separate definitive purchase agreement as described in Section 2 hereof. It is acknowledged that the number of Securities to be sold in the Offerings may be increased or decreased as described in the Prospectus (as hereinafter defined). If the number of Securities is increased or decreased in accordance with the Plan, the term “Securities” shall mean such greater or lesser number, where applicable.

In connection with the Offerings and pursuant to the terms of the Plan as described in the Prospectus, the Company has established the Foundation. Immediately following the consummation of the Offerings, subject to compliance with certain conditions as may be imposed by regulatory authorities, the Company will contribute newly issued shares of Common Stock in an amount equal to up to 2% of the Securities issued in the Offerings and to the MHC, or between 144,500 and 195,500 shares of Common Stock (subject to increase in certain circumstances to 224,825 shares).

The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-1 (No. 333-116381), including a related prospectus, for the registration of the Securities under the Securities Act of 1933, as amended (the “Securities Act”), has filed such amendments thereto, if any, and such amended prospectuses as may have been required to the date hereof by the Commission in order to declare such registration statement effective, and will file such additional amendments thereto and such amended prospectuses and prospectus supplements as may hereafter be required. Such registration statement (as amended to date, if applicable, and as from time to time amended or supplemented hereafter) and the prospectuses constituting a part thereof (including in each case all documents incorporated or deemed to be incorporated by reference therein and the information, if any, deemed to be a part thereof pursuant to the rules and regulations of the Commission under the Securities Act, as from time to time amended or supplemented pursuant to the Securities Act or otherwise (the “Securities Act Regulations”)), are hereinafter referred to as the “Registration Statement” and the “Prospectus,” respectively, except that if any revised prospectus shall be used by the Company in connection with the Subscription and Community Offerings or the Syndicated Community Offering, which differs from the Prospectus on file at the Commission at the time the Registration Statement becomes effective (whether or not such revised prospectus is required

SECTION 2. APPOINTMENT OF SANDLER O’NEILL; SALE AND DELIVERY OF THE SECURITIES; CLOSING. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby appoints Sandler O’Neill as its Agent to consult with and advise the Company, and to assist the Company with the solicitation of subscriptions and purchase orders for Securities, in connection with the Company’s sale of Common Stock in the Offerings. On the basis of the representations and warranties herein contained, and subject to the terms and conditions herein set forth, Sandler O’Neill accepts such appointment and agrees to use its best efforts to assist the Company with the solicitation of subscriptions and purchase orders for Securities in accordance with this Agreement; provided, however, that the Agent shall not be obligated to take any action which is inconsistent with any applicable laws, regulations, decisions or orders. The services to be rendered by Sandler O’Neill pursuant to this appointment include the following: (i) consulting as to the securities marketing implications of any aspect of the Plan or related corporate documents; (ii) reviewing with the Board of Directors of the Company, the MHC and the Bank financial and securities marketing implications of the Appraiser’s appraisal of the Common Stock; (iii) reviewing all offering documents, including the Prospectus, stock order forms and related offering materials (it being understood that preparation and filing of such documents is the sole responsibility of the Company, the MHC and the Bank and their counsel); (iv) assisting in the design and implementation of a marketing strategy for the

Offerings; (v) assisting management of the Company and the Bank in preparing for meetings with potential investors and broker-dealers; and (vi) providing such other general advice and assistance regarding financial and marketing aspects of the Offering as may be requested to promote the successful completion of the Offering.

The appointment of the Agent hereunder shall terminate upon the earlier to occur of (a) forty-five (45) days after the last day of the Subscription and Community Offerings, unless the Company and the Agent agree in writing to extend such period and the OTS agrees to extend the period of time in which the Securities may be sold, or (b) the receipt and acceptance of subscriptions and purchase orders for all of the Securities, or (c) the completion of the Syndicated Community Offering.

If any of the Securities remain available after the expiration of the Subscription and Community Offerings, at the request of the Company and the Bank, Sandler O’Neill will seek to form a syndicate of registered brokers or dealers (“Selected Dealers”) to assist in the solicitation of purchase orders of such Securities on a best efforts basis. Sandler O’Neill will endeavor to limit the aggregate fees to be paid by the Company and the Bank under any such Selected Dealers’ Agreement to an amount competitive with gross underwriting discounts charged at such time for underwritings of comparable amounts of stock sold at a comparable price per share in a similar market environment; provided, however, that the aggregate fees payable to Sandler O’Neill and Selected Dealers shall not exceed 7.0% of the aggregate purchase price of the Securities sold in the Syndicated Community Offering by such Selected Dealers. Sandler O’Neill will endeavor to distribute the Securities among the Selected Dealers in a fashion which best meets the distribution objective of the Company and the Bank and the requirements of the Plan, which may result in limiting the allocation of stock to certain Selected Dealers. It is understood that in no event shall Sandler O’Neill be obligated to act as a Selected Dealer or to take or purchase any Securities.

If any of the Securities remain available after the expiration of the Offerings, the Company agrees to offer the Agent the first right to act as lead managing underwriter for the Public Offering. The terms of the Public Offering will be set forth in a separate definitive purchase agreement in a form satisfactory to Sandler O’Neill and containing customary representations, warranties, conditions, agreements and indemnities, which purchase agreement, when executed, will supersede and replace this Agreement with respect to Securities sold thereunder (the “Purchase Agreement”). This Agreement is not intended to constitute, and should not be construed as, an agreement or commitment between the Company, the Bank and Sandler O’Neill relating to the firm commitment underwriting of any securities, and Sandler O’Neill may, in its sole judgment and discretion, determine at any time not to proceed with the proposed firm commitment underwriting. Such proposed underwriting will be subject, among other things, to: (i) satisfactory completion by Sandler O’Neill of such due diligence investigation or inquiries as it may deem appropriate, (ii) approval of the proposed underwriting by Sandler O’Neill’s commitment committee or such other authorization as may be required by its internal procedures, (iii) market conditions, which, in the sole judgment of Sandler O’Neill, shall be satisfactory, and (iv) the execution and delivery of a definitive Purchase Agreement.

In the event the Company is unable to sell at least the total minimum of the Securities, as set forth on the cover page of the Prospectus, within the period herein provided, this Agreement shall terminate and the Company shall refund to any persons who have subscribed for any of the Securities the full amount which it may have received from them, together with interest as provided in the Prospectus, and no party to this Agreement shall have any obligation to the others hereunder, except for the obligations of the Company, the MHC and the Bank as set forth in Sections 4, 6(a) and 7 hereof and the obligations of the Agent as provided in Sections 6(b) and 7 hereof. Appropriate arrangements for placing the funds received from subscriptions for Securities or other offers to purchase Securities in special interest-bearing accounts with the Bank until all Securities are sold and paid for were made prior to the commencement of the Subscription Offering, with provision for refund to the purchasers as set forth above, or for delivery to the Company if all Securities are sold.

If at least the total minimum of Securities, as set forth on the cover page of the Prospectus, are sold, the Company agrees to issue or have issued the Securities sold and to release for delivery certificates for such Securities at the Closing Time against payment therefor by release of funds from the special interest-bearing accounts referred to above. The closing shall be held at the offices of Muldoon Murphy Faucette & Aguggia LLP, at 10:00 a.m., local time, or at such other place and time as shall be agreed upon by the parties hereto, on a business day to be agreed upon by the parties hereto. The Company shall notify the Agent by telephone, confirmed in writing, when funds shall have been received for all the Securities. Certificates for Securities shall be delivered directly to the purchasers thereof in accordance with their directions. Notwithstanding the foregoing, certificates for Securities purchased through Selected Dealers shall be made available to the Agent for inspection at least 48 hours prior to the Closing Time at such office as the Agent shall designate. The hour and date upon which the Company shall release for delivery all of the Securities, in accordance with the terms hereof, is herein called the “Closing Time.”

The Company will pay any stock issue and transfer taxes which may be payable with respect to the sale of the Securities.

In addition to the reimbursement of the expenses specified in Section 4 hereof, the Agent will receive the following compensation for its services hereunder:

(a) One percent (1.00%) of the aggregate purchase price of the Securities sold in the Subscription and Community Offerings, excluding in each case shares purchased by (i) any employee benefit plan of the Company, the MHC or the Bank established for the benefit of their respective directors, officers and employees, and (ii) any director, officer or employee of the Company or the Bank or members of their immediate families (which term shall mean parents, grandparents, spouse, siblings, children and grandchildren); and

(b) With respect to any Securities sold by a National Association of Securities Dealers, Inc. (“NASD”) member firm (other than Sandler O’Neill) in the Syndicated Community Offering, (i) the compensation payable to Selected Dealers, (ii) any sponsoring dealer’s fees; and (iii) a management fee to Sandler O’Neill of one percent (1.00%) of the aggregate purchase price of the Securities sold in the Syndicated Community Offering. Any

fees payable to Sandler O’Neill for Securities sold by Sandler O’Neill or other NASD member firms under any such agreement shall be limited to an aggregate of seven percent (7.00%) of the purchase price of the Securities sold by Sandler O’Neill and other NASD member firms.

If this Agreement is terminated by the Agent in accordance with the provisions of Section 9(a) hereof, no fee shall be payable by the Company to Sandler O’Neill; provided, however, that the Company shall reimburse the Agent for all of its reasonable out-of-pocket expenses incurred prior to termination, including the reasonable fees and disbursements of counsel for the Agent in accordance with the provisions of Section 4 hereof. In addition, the Company shall be obligated to pay the fees and expenses as contemplated by the provisions of Section 4 hereof in the event of any such termination.

All fees payable to the Agent hereunder shall be payable in immediately available funds at Closing Time, or upon the termination of this Agreement, as the case may be. In recognition of the long lead times involved in the reorganization process, the Bank agrees to make advance payments to the Agent in the aggregate amount of $ 25,000, none of which has previously been paid and the remaining $25,000 of which shall be payable upon the execution hereof, which shall be credited against any fees or reimbursement of expenses payable hereunder.

(i) from and against any and all loss, liability, claim, damage and expense whatsoever, as incurred, related to or arising out of the Offerings (including the establishment of the Foundation and the contribution of the Foundation Shares thereto by the Company) or any action taken by the Agent where acting as agent of the Company, the MHC or the Bank or otherwise as described in Section 2 hereof;

the Company, the MHC or the Bank and the Agent, as incurred, in such proportions (i) that the Agent is responsible for that portion represented by the percentage that the financial and marketing advisor and conversion agent fees received by the Agent bears to the gross proceeds recovered by the Company in the Offerings and the Company, the MHC and the Bank are jointly and severally responsible for the balance or (ii) if, but only if, the allocation provided for in clause (i) is for any reason held unenforceable, in such proportion as is appropriate to reflect not only the relative benefits to the Company, the MHC and the Bank on the one hand and the Agent on the other, as reflected in clause (i), but also the relative fault of the Company, the MHC and the Bank on the one hand and the Agent on the other, as well as any other relevant equitable considerations; provided, however, that 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.
