Ladies and Gentlemen:

Narragansett Bancorp, Inc., a newly formed Maryland corporation (the “Company”), Narragansett Financial Corporation, a Massachusetts-chartered mutual holding company (the “MHC”), and BayCoast Bank, a Massachusetts-chartered stock savings bank (the “Bank” and collectively with the Company, and the MHC, the “Primary Parties”), hereby confirm their agreement with Piper Sandler & Co. (“PSC” or the “Agent”) with respect to the offer and sale by the Company of up to 7,912,000 shares (subject to increase up to 9,098,800 shares) of the Company’s common stock, par value $0.01 per share (the “Common Stock”). The shares of Common Stock to be sold by the Company in the Offerings (as hereinafter defined) are hereinafter called the “Securities.” 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 (as hereinafter defined), the term “Securities” shall mean such greater or lesser number, where applicable. In addition, the Company expects to contribute up to 2% of the number of shares of Common Stock to be outstanding upon completion of the Reorganization (as hereinafter defined) and/or cash to a charitable foundation (the “Foundation”) that the Company is establishing in connection with the Reorganization (such shares hereinafter being referred to as the “Foundation Shares.”), provided that the total contribution to the Foundation does not exceed 8% of the gross proceeds from the sale of Common Stock in the Offerings.

The Securities are being offered for sale, and the Foundation Shares are being contributed, in accordance with the Plan of Reorganization and Stock Issuance (the “Plan”) adopted by the Board of Trustees of the MHC and the Board of Directors of the Bank (collectively, with the Board of Directors of the Company, the “Boards of Directors”). Pursuant to the Plan, (i) the MHC will organize the Company as a separate wholly-owned subsidiary of the MHC, (ii) the MHC will contribute all of the shares of common stock of the Bank to the Company, which will result in the Company owning 100% of the common stock of the Bank, and (ii) the Company will offer to sell up to 49% of its Common Stock in the Offerings (collectively, the “Reorganization”). The Company expects to retain up to 50% of the net proceeds from the Offerings.

Pursuant to the Plan, the Company will offer rights to subscribe for the Securities in a subscription offering (the “Subscription Offering”) to: (i) certain depositors of the Bank; (ii) the Bank’s tax qualified employee benefit plans, including the employee stock ownership plan that may be established in connection with the Reorganization (the “ESOP”), and the BayCoast Bank 401(k) Plan (collectively with the ESOP, the “Employee Plans”); and (iii) employees, officers, directors, trustees and corporators of the Primary Parties who are not eligible under clause (i) of this sentence. To the extent Securities are not subscribed for in the Subscription Offering, such Securities may be offered to certain members of the general public in a community offering (the “Direct Community Offering”), with preference given first to persons who are natural persons and trusts of natural persons who are residents of the Local Community, as defined in the Plan, and finally to other members of the general public. 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 Direct Community Offering,” may be commenced concurrently with, during or after the Subscription Offering. It is currently anticipated that any Securities not subscribed for in the Subscription and Direct Community Offering will be offered, subject to Section 2 hereof, in a syndicated community offering (the “Syndicated Community Offering”) or a firm commitment underwritten public offering (the “Public Offering”). The Subscription and Community Offering, and the Syndicated Community Offering are hereinafter referred to collectively as the “Offerings.” If there is a Public Offering, the Public Offering will be governed by a separate underwriting agreement.

In accordance with Massachusetts General Laws and the rules and regulations regarding issuances of stock by subsidiaries of mutual holding companies (including, without limitation, Chapter 167H of the Massachusetts General Laws and Chapter 33, Subpart C of the Code of Massachusetts Regulations), as from time to time amended or supplemented (the “Massachusetts Banking Law”), the Company has filed the Plan and a letter application with respect to the Reorganization and the Offerings with the Massachusetts Division of Banks (the “Division”) and has filed such amendments thereto and supplementary materials as may have been required to the date hereof (such application, as amended to date, if applicable, and as subsequently amended, if applicable, is hereinafter referred to as the “Massachusetts Application”), including copies of the MHC’s Information Statement for a Special Meeting of its members relating to the Reorganization (the “Information Statement”), the Appraisal (as defined below), and the Prospectus.

In addition, in accordance with the Bank Holding Company Act of 1956, as amended (the “BHCA”), and the regulations (the “FRB Regulations”) of the Board of Governors of the Federal Reserve System (the “FRB”), the Company has filed an application on Form FR Y-3 for approval of its acquisition of the Bank (the “Holding Company Application”) in accordance with the rules and regulations of the FRB regarding issuances of stock by subsidiaries of mutual holding companies, as from time to time amended or supplemented (the “FRB Regulations”), . The Massachusetts Application and the Holding Company Application are collectively referred to herein as the “Applications.”

If at any time following issuance of an Issuer-Represented Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer-Represented Free Writing Prospectus materially conflicted or would materially conflict with the information contained in the Registration Statement or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that

subsequent time, not misleading, the Company will notify promptly the Agent so that any use of such Issuer-Represented Free Writing Prospectus may cease until it is amended or supplemented and the Company will promptly amend or supplement such Issuer-Represented Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission; provided, however, that this covenant shall not apply to any statements or omissions made in reliance upon and in conformity with the Agent Information.

(c) The Primary Parties will give the Agent notice of their intention to file or prepare any amendment to the Applications or the Registration Statement (including any post-effective amendment) or any amendment or supplement to the Prospectus (including any revised prospectus that the Company proposes for use in connection with any Syndicated Community Offering that 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 to be filed pursuant to Rule 424(b) of the Securities Act Regulations), the Information Statement, will furnish the Agent with copies of any such amendment or supplement a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file any such amendment or supplement or use any such prospectus to which the Agent or counsel for the Agent may reasonably object.

(d) The Primary Parties will deliver to the Agent as many signed copies and as many conformed copies of the Applications and the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein) as the Agent may reasonably request, and from time to time such number of copies of the Prospectus as the Agent may reasonably request.

(e) During the period when the Prospectus is required to be delivered, the Primary Parties will comply, at their own expense, with all requirements imposed upon them by the FRB and the Division, by the FRB Regulations and Massachusetts Banking Law, as from time to time in force, and by the Nasdaq Stock Market, the Securities Act, the Securities Act Regulations, the Exchange Act, and the Exchange Act Regulations, including, without limitation, Regulation M under the Exchange Act, so far as necessary to permit the continuance of sales or dealing in shares of Common Stock during such period in accordance with the provisions hereof and the Prospectus.

(f) If any event or circumstance shall occur as a result of which it is necessary, in the reasonable opinion of counsel for the Agent, to amend or supplement the Registration Statement or Prospectus in order to make the Prospectus not misleading in the light of the circumstances existing at the time it is delivered to a purchaser or if it is necessary to amend or supplement the Prospectus to comply with applicable law and regulation, the Primary Parties will forthwith amend or supplement the Registration Statement or Prospectus (in form and substance reasonably satisfactory to counsel for the Agent) so that, as so amended or supplemented, the Registration Statement or Prospectus will not include an 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 existing at the time it is delivered to a purchaser, not misleading or so the Prospectus will comply with applicable law and regulation, and the Company and the Bank will furnish to the Agent a reasonable number of copies of such amendment or supplement.

SECTION 6. INDEMNIFICATION.

(a) The MHC, the Company and the Bank, jointly and severally, agree to indemnify and hold harmless the Agent, each person, if any, who controls the Agent, within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and its respective partners, directors, officers, employees and agents as follows:

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

(ii) from and against any and all loss, liability, claim, judgment, damage and expense whatsoever, as incurred, based upon or arising out of (A) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus, the General Disclosure Package, any Issuer-Represented Free Writing Prospectus, the Information Statement, or any amendment or supplement thereto (including any post-effective amendment), (B) the omission or alleged omission to state a material fact required to be stated in the Registration Statement, the Prospectus, or the General Disclosure Package, any Issuer-Represented Free Writing Prospectus, the Information Statement or necessary to make the statements therein not misleading or (C) any omission or alleged omission from the Prospectus, the General Disclosure Package, any Issuer-Represented Free Writing Prospectus, or the Information Statement to state therein a material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading;

(iii) from and against any and all loss, liability, claim, judgment, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever described in clauses (i) or (ii) above, if such settlement is effected with the written consent of the Company, the MHC or the Bank, which consent shall not be unreasonably withheld; and

(iv) from and against any and all expense whatsoever, as incurred (including, subject to Section 6(c) hereof, the fees and disbursements of counsel chosen by the Agent), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation, proceeding or inquiry by any governmental agency or body, commenced or threatened, or any claim pending or threatened whatsoever described in clauses (i) or (ii) above, to the extent that any such expense is not paid under clause (i), (ii) or (iii) above;

provided, however, that the indemnification provided for in this paragraph (a) shall not apply to any loss, liability, claim, judgment, damage or expense that arises out of any untrue statement or alleged untrue statement of a material fact contained in the Prospectus or the General Disclosure Package or any Issuer-Represented Free Writing Prospectus (or any amendment or supplement thereto), 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 which was made in reliance upon and in conformity with the written information furnished to the Company by the Agent expressly for use therein, provided that the MHC, the Company and the Bank hereby acknowledge and agree that the only information that the Agent has furnished to the Company consists solely of the information set forth in the section “The Reorganization and Plan of Distribution—Marketing and Distribution; Compensation” in the Prospectus. To the extent required by law, the indemnification provided for in this paragraph shall be subject to and limited by Section 23A of the Federal Reserve Act, as amended.

(b) The Agent agrees to indemnify and hold harmless the MHC, the Company and the Bank, their directors, each of their officers who signed the Registration Statement, and each person, if any, who controls the MHC, the Company, and the Bank within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any and all loss, liability, claim, judgment, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, of a material fact made in the Prospectus or the General Disclosure Package or any Issuer-Represented Free Writing Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Agent Information.

(c) Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability that it may have otherwise than on account of this indemnity agreement. If any such action shall be brought or asserted against an indemnified party and such indemnified party shall have notified the indemnifying party thereof, the indemnifying party shall retain counsel reasonably satisfactory to the indemnified party (who shall not, without the consent of the indemnified party, be counsel to the indemnifying party) to represent the indemnified party in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the contrary; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party shall have reasonably concluded that there may be legal defenses available to such indemnified party that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interest between them. An indemnifying party may participate at its own expense in the defense of any such action. The indemnifying party shall not be liable for the fees and expenses of more than one counsel (in addition to no more than one local counsel in each separate jurisdiction in which any action or proceeding is commenced) separate from such indemnifying party’s own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. Notwithstanding anything to the contrary in this Section 6, the indemnifying party shall not, without the prior written consent of an indemnified party (which consent shall not be unreasonably withheld), effect any settlement of any pending or threatened action in respect of which indemnity could have been sought hereunder by such indemnified party unless (i) such settlement includes an unconditional release of such indemnified party in form and substance satisfactory to such indemnified party from all liability on claims that are the subject matter of such action and (ii) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) The MHC, the Company and the Bank also agree that the Agent shall not have any liability (whether direct or indirect, in contract or tort or otherwise) to the MHC, the Bank, the Company and its security holders or the MHC’s, the Bank’s, or the Company’s creditors relating to or arising out of the engagement of the Agent pursuant to, or the performance by the Agent of the services contemplated by, this Agreement, except to the extent that any liability is found in a final judgment by a court of competent jurisdiction to have resulted primarily from the Agent’s bad faith, willful misconduct or gross negligence.

(e) In addition to, and without limiting, the provisions of Section (6)(a)(iv) hereof, in the event that the Agent, any person, if any, who controls the Agent within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act or any of its partners, directors, officers, employees, affiliates or agents is requested or required to appear as a witness or otherwise gives testimony in any action, proceeding, investigation or inquiry brought by or on behalf of or against the MHC, the Company, the Bank, the Agent or any of its affiliates or any participant in the transactions contemplated hereby in which the Agent or such person or agent is not named as a defendant, the MHC, the Company and the Bank jointly and severally agree to reimburse the Agent and its partners, directors, officers, employees or agents for all reasonable and necessary out-of-pocket expenses incurred by them in connection with preparing or appearing as a witness or otherwise giving testimony and to compensate the Agent and its partners, directors, officers, employees or agents in an amount to be mutually agreed upon.

(f) Notwithstanding any other provision set forth in this Section 6, in no event shall any payments made by the Company, the MHC or the Bank pursuant to this Section 6 exceed the amount permissible under applicable federal law, including, without limitation, Section 18(k) of the Federal Deposit Insurance Act and the regulations promulgated thereunder.

SECTION 7. CONTRIBUTION. In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in Section 6 hereof is for any reason held to be unenforceable by the indemnified parties although applicable in accordance with its terms or is insufficient in respect of any losses, liabilities, claims, judgments, damages or expenses referred to therein, the MHC, the Company, the Bank, and the Agent shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by the MHC, the Company 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 maximum aggregate marketing fees appearing on the cover page of the Prospectus bears to the maximum aggregate gross proceeds appearing thereon and the MHC, the Company 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 MHC, the Company 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 MHC, the Company 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. For purposes of this Section, each person, if any, who controls the Agent within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and its respective partners, directors, officers, employees, affiliates and agents shall have the same rights to contribution as the Agent, and each director of the MHC, each director of the Company, and the Bank, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the MHC, the Company or the Bank within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the MHC, the Company and the Bank. Notwithstanding anything to the contrary set forth herein, to the extent permitted by applicable law, in no event shall the Agent be required to contribute an aggregate amount in excess of the aggregate marketing fees to which the Agent is entitled and actually paid pursuant to this Agreement.

SECTION 8. REPRESENTATIONS, WARRANTIES AND AGREEMENTS TO SURVIVE DELIVERY. All representations, warranties and agreements contained in this Agreement, or contained in certificates of officers of the MHC, the Company or the Bank submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of the Agent or controlling person, or by or on behalf of the Company, and shall survive delivery of the Securities.

SECTION 9. TERMINATION OF AGREEMENT

(b) If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Sections 2 and 4 hereof relating to the reimbursement of expenses and except that the provisions of Sections 6 and 7 hereof shall survive any termination of this Agreement.
