 Ladies and Gentlemen: 
 The Community Bank, a Massachusetts
co-operative bank (the “Bank”), Campello Bancorp, a Massachusetts mutual holding company and the current owner of 100% of the common stock of the Bank (the “MHC”) and Campello Bancorp, Inc., a Maryland corporation organized to be
the successor to the MHC (the “Holding Company,” and collectively with the Bank, the MHC and each of their respective subsidiaries, the “Primary Parties”) hereby confirm, jointly and severally, their agreement with Stifel,
Nicolaus & Company, Incorporated (the “Agent”), as follows: 
 Section 1. The Offering. On
April 17, 2008, the Board of Directors of each of the Bank and MHC, adopted a Plan of Conversion and Reorganization, amended on June 19, 2008 and September 9, 2008 (the “Plan”) which provides for the conversion of the MHC
from the mutual to the capital stock form of organization through the merger of MHC with the Bank, the issuance of all of the Bank’s outstanding common stock to the Holding Company and the issuance of all of the outstanding common stock of the
Holding Company in the Offerings (defined below) (the “Conversion”). Upon completion of the Conversion, the Bank will be a wholly owned subsidiary of the Holding Company. As part of the Plan, the Holding Company is offering up to 2,300,000
shares (subject to an increase up to 2,645,000 shares) (the “Shares”) of common stock, par value $0.01 per share (the “Common Stock”), in (i) a subscription offering (the “Subscription Offering”), and, if
necessary, (ii) a direct community offering (the “Community Offering”) and (iii) a syndicated community offering (the “Syndicated Community Offering” and collectively with the Subscription Offering and the Community
Offering, the “Offerings”), in connection with the Conversion. The Plan also provides that the Company shall 








 
contribute shares in an amount of up to 4.75% of the Shares of its Common Stock sold in the Offerings (the “Foundation Shares”) and cash in an
amount of up to 0.25% of the value of the Shares of its Common Stock sold in the Offerings, to a charitable foundation to be established by the Holding Company (the “Charitable Foundation”). References to the Bank herein shall include the
Bank in its current form and post-Conversion as a wholly-owned subsidiary of the Holding Company, as applicable. 
 Upon the completion of
the Offerings, the purchasers of Shares in the Offerings will own up to 95.5% of the outstanding Common Stock and the Charitable Foundation will own up to 4.5% of the outstanding Common Stock. The Holding Company will issue the Shares at a purchase
price of $10.00 per share (the “Purchase Price”). If the number of Shares is increased or decreased in accordance with the Plan, the term “Shares” as used herein shall mean such greater or lesser number, where applicable.

 In the Subscription Offering, non-transferable rights to subscribe for between 1,700,000 and 2,300,000 Shares (subject to an increase up
to 2,645,000 Shares) of the Common Stock (“Subscription Rights”) will be granted, in the following order of priority: (1) the Bank’s depositors with account balances of at least $50.00 as of the close of business on
December 31, 2006 (“Eligible Account Holders”); (2) the Bank’s depositors, other than directors or officers of the Bank or corporators of MHC, and their associates, with account balances of at least $50.00 as of the close of
business on March 31, 2008 (“Supplemental Eligible Account Holders”); (3) the Bank’s or the Holding Company’s tax-qualified employee stock benefit plans; and (4) the Bank’s employees, officers and directors
and the corporators of MHC (the “Bank Participants”), subject to the priorities and purchase limitations set forth in the Plan. The Holding Company may offer Shares, if any, remaining after the Subscription Offering in a Community Offering
on a priority basis to natural persons and trusts of natural persons residing within the Massachusetts municipalities of Abington, Acushnet, Attleborough, Barnstable, Berkley, Bourne, Brewster, Bridgewater, Brockton, Carver, Chatham, Dennis,
Dighton, Duxbury, E. Bridgewater, Eastham, Easton, Fairhaven, Falmouth, Freetown, Halifax, Hanover, Hanson, Harwich, Kingston, Lakeville, Mansfield, Marion, Marshfield, Mashpee, Mattapoisett, Middleborough, North Attleborough, Norton, Norwell,
Orleans, Pembroke, Plymouth, Plympton, Provincetown, Raynham, Rehoboth, Rochester, Rockland, Sandwich, Scituate, Taunton, Truro, Wareham, Wellfleet, West Bridgewater, Whitman and Yarmouth, and then to the general public. In the event a Community
Offering is held, it may be held at any time during or immediately after the Subscription Offering. Depending on market conditions, Shares available for sale but not subscribed for in the Subscription Offering or purchased in the Community Offering
may be offered in the Syndicated Community Offering to selected members of the general public through a syndicate of registered broker-dealers managed by the Agent which are members of the Financial Industry Regulatory Authority (“FINRA”).

 It is acknowledged that the number of Shares to be sold in the Offerings may be increased or decreased as described in the Prospectus (as
hereinafter defined); that the purchase of Shares in the Offerings is subject to maximum and minimum purchase limitations as described in the Prospectus; and that the Holding Company may reject, in its sole discretion, in whole or in part, any
subscription received in the Community Offering and Syndicated Community Offering.

 The Holding Company has filed with the U.S. Securities and Exchange Commission (the
“Commission”) a Registration Statement on Form S-1 (File No. 333-152391) in order to register the Shares under the Securities Act of 1933, as amended (the “1933 Act”), and the regulations promulgated thereunder (the
“1933 Act Regulations”), and has filed such amendments thereto as have been required to the date hereof (the “Registration Statement”). The prospectus, as amended, included in the Registration Statement at the time it initially
became effective is hereinafter called the “Prospectus,” except that if any prospectus relating to the Offerings is filed by the Holding Company pursuant to Rule 424(b) or (c) of the 1933 Act Regulations differing from the prospectus
included in the Registration Statement at the time it initially becomes effective, the term “Prospectus” shall refer to the prospectus filed pursuant to Rule 424(b) or (c) from and after the time said prospectus is filed with the
Commission and shall include any amendments and supplements thereto from and after their dates of effectiveness or use, respectively. 
 In
accordance with Chapter 167H, Section 9 of the Massachusetts General Laws and Chapter 33 of the Massachusetts Administration Code (the “Conversion Regulations”), the MHC and the Bank have filed with the Massachusetts Division of Banks
(the “Division”) an Application for Conversion (the “Conversion Application”) and the MHC and the Bank have filed with the Federal Deposit Insurance Corporation (the “FDIC”) an Interagency Bank Merger Act Application
(the “Merger Application). In connection with the Conversion, the Holding Company filed with the Federal Reserve Bank of Boston (the “FRB”) applications on Form FRY-3 and Form FRY-4 (the “BHC Application,” and together with
the Conversion Application and the Merger Application, the “Applications”), for the Holding Company to become a bank holding company with respect to the Bank. 
 Concurrently with the execution of this Agreement, the Holding Company is delivering to the Agent copies of the Prospectus dated September 11, 2008 of the Holding Company to be used in the Subscription Offering
and Community Offering (if any), and, if necessary, will deliver copies of the Prospectus and any prospectus supplement for use in a Syndicated Community Offering. 
 Section 2. Appointment of Agent. Subject to the terms and conditions of this Agreement, the Primary Parties hereby appoint the Agent to consult with, advise and assist the Primary Parties in
connection with the sale of the Shares in the Offerings. 
 On the basis of the representations and warranties of the Primary Parties
contained in, and subject to the terms and conditions of, this Agreement, the Agent accepts such appointment and agrees to use its best efforts to assist the Primary Parties with the solicitation of subscriptions and purchase orders for the Shares
and agrees to consult with and advise the Primary Parties as to the matters set forth in Section 2 of the amended and restated letter agreement, effective as of April 23, 2008, between the MHC, the Bank and Agent (the “Letter

with any applicable law, regulation, decision or order. Except as provided in the last paragraph of this Section 2 and Section 13 hereof, the appointment of the Agent to provide services hereunder shall terminate upon consummation of the
Offerings.

 If selected broker-dealers are used to assist in the sale of Shares in the Syndicated Community Offering,
the Primary Parties hereby, subject to the terms and conditions of this Agreement, appoint the Agent to manage such broker-dealers in the Syndicated Community Offering. On the basis of the representations and warranties of the Primary Parties
contained in, and subject to the terms and conditions of, this Agreement, the Agent accepts such appointment and agrees to manage the selling group of broker-dealers in the Syndicated Community Offering. 
 Section 3. Refund of Purchase Price. In the event that the Offerings are not consummated for any reason, including but not limited to
the inability to sell a minimum of 1,700,000 Shares during the Offerings (including any permitted extension thereof) or such other minimum number of Shares as shall be established consistent with the Plan and the Conversion Regulations, this
Agreement shall terminate and any persons who have subscribed for or ordered any of the Shares shall have refunded to them the full amount which has been received from such person, together with interest, if applicable, as provided in the Prospectus
and the Plan. Upon termination of this Agreement, neither the Agent nor the Primary Parties shall have any obligation to the other except that (i) the Primary Parties shall remain liable for any amounts due pursuant to Sections 4, 9, 11 and 12
hereof, unless the transaction is not consummated due to the breach by the Agent of a warranty, representation or covenant; and (ii) the Agent shall remain liable for any amount due pursuant to Sections 11 and 12 hereof, unless the transaction
is not consummated due to the breach by the Primary Parties of a warranty, representation or covenant. 
 Section 4. Fees.
In addition to the expenses specified in Section 9 hereof, as compensation for the Agent’s services under this Agreement, the Agent has received or will receive the following fees from the Primary Parties: 
 (a) A conversion and depositor vote advisory and administrative services fee of $50,000 paid as follows: (i) $12,500 was paid upon execution of the
Letter Agreement, (ii) $25,000 will be paid in connection with the initial filing of the Registration Statement, and (iii) $12,500 will be paid upon final approval by the Board of Directors of the Holding Company to commence the Offerings.

 (b) A sales fee of one percent (1.0%) of the dollar amount of the Shares sold in the Subscription Offering and Community Offering,
excluding (i) additional Shares sold pursuant to Section 4(c) below, (ii) Shares purchased by the Bank’s officers, directors, or employees (or members of their immediate families), (iii) Shares purchased by any tax-qualified
or non-qualified employee benefit plans of the Bank or the officers, directors or employees (or members of their immediate families), and (iv) the Foundation Shares, which fee shall be paid at Closing (as defined in Section 5). For
purposes of this Agreement, “immediate family” includes an officer’s, director’s or employee’s spouse, parents, siblings and children who live in the same house as the officer, director or employee. 
 (c) If any of the Shares remain unsubscribed after the Subscription Offering and Community Offering, at the request of the Holding Company, Agent, as
sole manager, will form a group of approved broker-dealer firms (the “Assisting Brokers”) in accordance with 

  

 4 








 
Section 2 hereof for purposes of the Syndicated Community Offering. The fees payable by the Holding Company pursuant to this Section 4(c) will not
exceed six percent (6.0%) of the aggregate dollar amount of the Shares sold in the Syndicated Community Offering. Of such fee, the Agent will receive one percent (1.0%) of the aggregate dollar amount of the Shares sold pursuant to this
Section 4(c) as a management fee, and the Primary Parties will pay the remainder to the Assisting Brokers, which may include the Agent, in amounts relating to the number of Shares sold by such Assisting Brokers pursuant to this
Section 4(c). All such fees payable under this Section 4(c) shall be in addition to all fees payable under Section 4(a) and 4(b) and shall be paid at Closing (as defined in Section 5). A form of Assisting Brokers Agreement is
attached hereto as Exhibit B. 
 In the event that the Holding Company is required to resolicit subscribers for Shares in the
Subscription Offering and Community Offering and the Agent is required to provide significant additional services in connection with such a resolicitation, the Primary Parties and the Agent shall mutually agree to the dollar amount of additional
compensation due to the Agent, if any, which shall not exceed $50,000. Until any agreement called for by this paragraph is reached, the Agent shall not incur any expenses relating to any resolicitation in an amount that would cause the total
expenses incurred by the Agent that are reimbursable by the Primary Parties pursuant to Section 9 hereof to be greater than those permitted without the prior written consent of the Holding Company or the Bank, which consent shall not be
unreasonably withheld. 
 If this Agreement is terminated in accordance with the provisions of Section 3 or 14 hereof and the sale of
the Shares is not consummated, the Agent shall not be entitled to receive the fees set forth in Sections 4(b)-(c), but the Agent will be entitled to retain the advisory and administrative services fee of $50,000 set forth in Section 4(a) and
the Primary Parties will reimburse the Agent for its reasonable expenses pursuant to Section 9 hereof. 
 Section 5.
Closing. If the minimum number of Shares required to be sold in the Offerings on the basis of the most recently updated Appraisal (as defined in Section 6(k)) are subscribed for at or before the termination date of the Offerings
(which may be extended), and the other conditions (including those in Section 10) to the completion of the Conversion are satisfied, the Holding Company agrees to issue the Shares against payment therefor and issue and contribute the Foundation
Shares on the Closing Time (as hereinafter defined) by the means authorized by the Plan and to deliver certificates evidencing ownership of the Shares and the Foundation Shares in such authorized denominations and registrations directly to the
purchasers thereof or as instructed as promptly as practicable after the Closing Time. The closing (the “Closing”) shall be held at the offices of special counsel to the Primary Parties, or at such other place as shall be agreed upon among
the Primary Parties and the Agent, at 10:00 a.m., Eastern Standard Time, on the business day selected by the Holding Company which business day shall be no less than two business days following the giving of prior notice by the Holding Company to
the Agent or at such other time as shall be agreed upon by the Primary Parties and the Agent. At the Closing, the Primary Parties shall deliver to the Agent by wire transfer in same-day funds the commissions, fees and expenses owing to the Agent as
set forth in Sections 4 and 9 hereof and the opinions required hereby and other documents deemed reasonably necessary for the Agent, including those required by Section 10 hereof, shall be executed and delivered to effect the sale of the Shares
as contemplated hereby and pursuant to the terms of the Prospectus. The 

  

 5 








 
Holding Company shall notify the Agent when funds shall have been received for the minimum number of Shares of the Common Stock. The hour and date upon which
the Holding Company shall release the Shares and the Foundation Shares for delivery in accordance with the terms hereof is referred to herein as the “Closing Time.” 
 The Agent shall have no liability to any party for the records or other information provided by the Primary Parties (or their respective agents) to the
Agent for use in allocating the Shares. Subject to the limitations of Section 11 hereof, the Primary Parties shall indemnify and hold harmless the Agent for any liability arising out of the allocation of the Shares in accordance with
(i) the Plan generally, and (ii) the records or other information provided to the Agent by the Primary Parties (or their respective agents). 
 Section 6. Representations and Warranties of the Primary Parties. The Primary Parties jointly and severally represent and warrant to the Agent that, except as disclosed in the Prospectus:

Agreement and the Letter Agreement and the consummation of the transactions herein contemplated, including the establishment and funding of the Charitable Foundation, have been duly and validly authorized by all necessary corporate action on the

Primary Parties, and is a valid, legal and binding obligation of each of the Primary Parties, in each case enforceable in accordance with its terms, except to the extent, if any, that the provisions of Sections 11 and 12 hereof may be unenforceable
as against public policy, and except to the extent that such enforceability may be limited by bankruptcy laws, insolvency laws, or other laws affecting the enforcement of creditors’ rights generally, or the rights of creditors of savings
institutions insured by the FDIC (including the laws relating to the rights of the contracting parties to equitable remedies). 
 (b) The

164 and 433 for the use of a free writing prospectus. If required to be filed, the Holding Company has filed any issuer free writing prospectus related to the offered Shares at the time it is required to be filed under Rule 433 and, if not required
to be filed, will retain such free writing prospectus in the Holding Company’s records pursuant to Rule 433(g) and if any issuer free writing prospectus is used after the date hereof in connection with the offering of the Shares the Holding
Company will file or retain such free writing prospectus as required by Rule 433. 
 (d) As of the Applicable Time (as defined below),
neither (i) the Issuer Represented General Free Writing Prospectus(es) (as defined below) issued at or prior to the Applicable Time and the Statutory Prospectus (as defined below), all considered together (collectively, the “General

omitted 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 any
Prospectus included in the Registration Statement relating to the offered Shares or any Issuer Represented Free Writing Prospectus (as defined below) based upon and in conformity with written information furnished to the Primary Parties by the Agent
specifically for use therein. As used in this paragraph and elsewhere in this Agreement:

without restriction pursuant to Rule 433(d)(8)(ii) under the 1933 Act Regulations or otherwise, even though not required to be filed with the Commission.

Holding Company notified or notifies the Agent (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
relating to the offered Shares, including any document incorporated by reference therein that has not been superseded or modified. If at any time following the date of first use 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 conflicted or would conflict with the information contained in the Registration Statement relating to the offered Shares 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 Holding Company has
notified or 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 Holding Company has promptly amended or will promptly amend or supplement such Issuer
Represented Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission. The foregoing two sentences do not apply to statements in or omissions from any Issuer Represented Free Writing Prospectus based upon and in
conformity with written information furnished to the Primary Parties by the Agent specifically for use therein.

adopted by the Board of Directors of the Bank. The Plan and the information statement with respect to the special meeting of the members of the Bank to approve the Conversion (the “Information Statement”) have been reviewed and deemed

necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that representations or warranties in this subsection (g) shall not apply to statements or omissions made in
reliance upon and in conformity with written information furnished to the Primary Parties by the Agent expressly regarding the Agent for use in the Prospectus under the captions “Market for the Common Stock” and “The Conversion and
Offering—Plan of Distribution; Selling Agent Compensation” or for use in any Blue Sky Applications or any Sales Information. 
 (h)
No order has been issued by the Division, the FDIC, the FRB, the Commission, or any other state or federal regulatory authority, preventing or suspending the use of the Registration Statement or the Prospectus and no action by or before any such
government entity to revoke any approval, authorization or order of effectiveness related to the Conversion or Offerings is pending or, to the knowledge of the Primary Parties, threatened.

Application is approved by the FRB and the Merger Application is approved by the FDIC, and at all times subsequent thereto until the Closing Time, the BHC Application and the Merger Application each complied and will comply as to form in all
material respects with all applicable rules and regulations and did not and will not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading.

applicable statutes and regulations (including, without limitation, regulations, decisions, directives and orders of the Division, the FDIC, the FRB and the Commission), except where the failure to so comply would not reasonably be expected to
result in a Material Adverse Effect and there is no charge, investigation, action, suit or proceeding before or by any court, regulatory authority or governmental agency or body pending or, to the knowledge of any of the Primary Parties, threatened,
which would reasonably be expected to materially and adversely affect the Conversion, the Offerings, the performance of this Agreement, or the consummation of the transactions contemplated in the Plan as described in the Registration Statement, or
which would reasonably be expected to result in a Material Adverse Effect.

business; (iii) entered into a financial or management consulting agreement except for the Letter Agreement and as contemplated hereunder; or (iv) engaged any intermediary between the Agent and the Primary Parties in connection with the
Offerings or the offering of shares of the common stock of the Bank, and no person is being compensated in any manner for such services.

bankruptcy laws, insolvency laws, or other laws affecting the enforcement of creditors’ rights generally or general equity principles.

Regulations or other applicable law, or the threat of any such action; or (vi) of the issuance by the Commission, the Division, the FDIC, the FRB, or any Bank authority of any stop order suspending the effectiveness of the Registration

 17 








 
the issuance by the Commission, the Division, the FDIC, the FRB, or any other state or federal authority of any order referred to in (v) and
(vi) above and, if any such order shall at any time be issued, to obtain the lifting thereof at the earliest possible time.

in all material respects, at their own expense, with all requirements imposed upon them by the Division, the FDIC, the FRB, the Conversion Regulations (except as modified or waived by the Division, the FDIC or the FRB, as applicable, provided that,
if any such modification or waiver is not in writing, the Primary Parties shall promptly notify the Agent in writing of the details of such modification or waiver), the Commission, by applicable state and federal law and regulations and by the 1933
Act, the 1933 Act Regulations, the 1934 Act and the 1934 Act Regulations, in each case as from time to time in force, so far as is 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.

is or becomes aware as a result of which the Registration Statement and/or Prospectus, as then supplemented or amended, would include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements
therein not misleading. If it is necessary, in the reasonable opinion of counsel for the Primary Parties, to amend or supplement the Registration Statement or the Prospectus in order to correct such untrue statement of a material fact or to make the
statements therein not misleading in light of the circumstances existing at the time of their use, the Primary Parties will, at their expense, prepare, file with the Commission and the Division, the FDIC, or the FRB, as necessary, and furnish to

statements therein, in light of the circumstances existing at

may from time to time reasonably request.

cooperation with the Agent, to register or to qualify the Shares and Foundation Shares for offer and sale (or contribution to the Charitable Foundation in the case of the Foundation Shares) or to exempt such Shares and Foundation Shares from
registration and to exempt the Holding Company and its officers, directors and employees from registration as broker-dealers, under the applicable securities laws of the jurisdictions in which the Offerings will be conducted; provided, however, that
the Holding Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation to do business in any jurisdiction in which it is not so qualified. In each jurisdiction where any of the Shares or
Foundation Shares shall have been registered or qualified as above provided, the Holding Company will make and file such statements and reports in each year as are or may be required by the laws of such jurisdiction.

 (m) Prior to
the Closing Time, the Holding Company shall register its Common Stock under Sections 12(b) of the 1934 Act. The Holding Company shall maintain the effectiveness of such registration for not less than three years or such shorter period as permitted
by the Division, the FDIC and the FRB. 
  

 19

to be satisfied each condition set forth in Section 10 hereof, unless such condition is waived in writing by Agent.

Parties will reimburse all reasonable out-of-pocket expenses incurred in connection with that offering phase which shall not exceed 1% of the gross proceeds of the offering. In the event that the Agent incurs any expenses on behalf of the Primary
Parties, the Primary Parties will pay or reimburse Agent for such expenses regardless of whether the Conversion is successfully completed, and such reimbursements will not be included in the expense limitations set forth in this paragraph. The Agent
will not incur any single out-of-pocket expense on behalf of the Primary Parties of more than $1,000 without the prior approval of the Holding Company. Not less than two days prior to the Closing Time, Agent will provide the Holding Company with a
detailed accounting of all reimbursable expenses to be paid at the Closing. 
 Section 10. Conditions to the Agent’s
Obligations. The obligations of the Agent hereunder and the occurrence of the Closing, the Conversion and the Offerings are subject to the condition that all representations and warranties of the Primary Parties herein contained are, at


  

 22 








 
and as of the commencement of the Offerings and at and as of the Closing Time, true and correct, the condition that the Primary Parties shall have performed
all of their obligations hereunder to be performed on or before such dates and to the following further conditions: 
 (a) The Conversion
Application and the Information Statement shall have been approved by the Division. The Registration Statement shall have been declared effective by the Commission, the BHC Application shall have been approved by the FRB, the Merger Application
shall have been approved by the FDIC, and no stop order or other action suspending the effectiveness of the Registration Statement shall have been issued under the 1933 Act or proceedings therefore initiated or, to any of the Primary Parties’
knowledge, threatened by the Commission or any state authority and no order or other action suspending the authorization for use of the Prospectus or the consummation of the Conversion shall have been issued or proceedings therefore initiated or, to
any of the Primary Parties’ knowledge, threatened by the Division, the FDIC, the FRB, the Commission, or any other governmental body. 
 (b) At the Closing Time, Agent shall have received: 
 (i) The favorable opinion, dated as of the Closing Time, of Luse Gorman
Pomerenk & Schick, P.C. in form and substance satisfactory to counsel for Agent, as set forth in Exhibit C. In rendering such opinion, such counsel may rely (A) as to matters involving the application of laws of any jurisdiction
other than the United States, to the extent such counsel deems proper and specified in such opinion, upon the opinion of other counsel reasonably acceptable to the Agent, as long as such other opinion indicates that the Agent may rely on the
opinion, and (B) as to matters of fact, to the extent such counsel deems proper, on certificates of responsible officers of the Primary Parties and public officials; provided copies of any such opinion(s) or certificates of public officials are
delivered to Agent together with the opinion to be rendered hereunder by counsel to the Primary Parties. The opinion of such counsel for the Primary Parties shall state that it has no reason to believe that the Agent is not reasonably justified in
relying thereon. The opinion of such counsel for the Primary Parties also shall state that the Agent’s counsel may rely for purposes of its own opinion on the opinion of such counsel and, if applicable, local counsel, whose opinion(s) shall
expressly authorize such reliance. 
 (ii) The letter of Luse Gorman Pomerenk & Schick, P.C. in form and substance to the effect
that during the preparation of the Registration Statement and the Prospectus, Luse Gorman Pomerenk & Schick, P.C. participated in conferences with certain officers of and other representatives of the Primary Parties, counsel to Agent,
representatives of the independent registered public accounting firm for the Primary Parties and representatives of Agent at which the contents of the Registration Statement and the Prospectus and related matters were discussed and has considered
the matters required to be stated therein and the statements contained therein and, although (without limiting the opinions provided pursuant to Section 10(b)(i)) Luse Gorman Pomerenk & Schick, P.C. has not independently verified the
accuracy, completeness or fairness of the statements contained in the Registration Statement and Prospectus, on the basis of the foregoing, nothing has come to the attention of Luse Gorman Pomerenk & Schick, P.C. that caused Luse Gorman
Pomerenk & Schick, P.C. to believe that the Registration Statement at the time it was declared effective by the Commission and as of the date of such letter or that the General Disclosure Package as of the Applicable Time, contained or


  

 23 








 
contains any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not misleading (it being understood that counsel need express no comment or opinion with respect to the financial statements, notes to financial statements, schedules and other
financial and statistical data included, or statistical or appraisal methodology employed, in the Registration Statement, Prospectus or General Disclosure Package). 
 (iii) The favorable opinion, dated as of the Closing Time, of Paul, Hastings, Janofsky & Walker LLP, with respect to such matters as the Agent may reasonably require. In rendering such opinion, such counsel
may rely (A) as to matters involving the application of laws of any jurisdiction other than the United States, to the extent such counsel deems proper and specified in such opinion, upon the opinion of other counsel reasonably acceptable to the
Agent, as long as such other opinion indicates that the Agent may rely on the opinion, (B) as to matters of fact, to the extent such counsel deems proper, on certificates of responsible officers of the Primary Parties and public officials; and
(C) the opinion of Luse Gorman Pomerenk & Schick, P.C. and, if applicable, local counsel, whose opinion(s) shall expressly authorize such reliance. 
 (iv) The letter of Paul, Hastings, Janofsky & Walker LLP, counsel for Agent, in form and substance to the effect that during the preparation of the Registration Statement and the Prospectus, Paul, Hastings,
Janofsky & Walker LLP participated in conferences with certain officers of and other representatives of the Primary Parties, counsel to the Primary Parties, representatives of the independent registered public accounting firm for the
Primary Parties and representatives of Agent at which the contents of the Registration Statement and the Prospectus and related matters were discussed and has considered the matters required to be stated therein and the statements contained therein
and, although (without limiting the opinions provided pursuant to Section 10(b)(iii)) Paul, Hastings, Janofsky & Walker LLP has not independently verified the accuracy, completeness or fairness of the statements contained in the
Registration Statement and Prospectus, on the basis of the foregoing, nothing has come to the attention of Paul, Hastings, Janofsky & Walker LLP that caused Paul, Hastings, Janofsky & Walker LLP to believe that the Registration
Statement at the time it was declared effective by the Commission and as of the date of such letter or that the General Disclosure Package as of the Applicable Time, contained or contains any untrue statement of a material fact or omitted to state
any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading (it being understood that counsel need express no comment or opinion with respect
to the financial statements, notes to financial statements, schedules and other financial and statistical data included, or statistical or appraisal methodology employed, in the Registration Statement, Prospectus or General Disclosure Package).

 (v) A blue sky memorandum from Luse Gorman Pomerenk & Schick, P.C. addressed to the Primary Parties and Agent relating to the
Offerings, including the Agent’s participation therein. The blue sky memorandum will address the necessity of obtaining or confirming exemptions, qualifications or the registration of the Common Stock under applicable state securities law.

  

 24 








 (c) Concurrently with the execution of this Agreement, Agent shall receive a letter from KPMG LLP, dated
the date hereof and addressed to Agent, such letter (i) confirming that KPMG LLP is an independent registered public accounting firm within the meaning of the Code of Ethics of the AICPA, that it is registered with the PCAOB, and that it is,
with respect to each of the Primary Parties, an independent certified public accountant within the meaning of, and is not in violation of the auditor independence requirements of, the 1933 Act, the 1933 Act Regulations, the Sarbanes-Oxley Act and
the PCAOB Regulations; and no information concerning its relationship with or interests in the Primary Parties is required by Item 13 of the Registration Statement, and stating in effect that in KPMG LLP’s opinion the financial statements
of MHC and the Bank included in the Prospectus comply as to form in all material respects with the applicable accounting requirements of the 1933 Act and the 1933 Act Regulations,; (ii) stating in effect that, on the basis of certain agreed
upon procedures (but not an audit examination in accordance with the auditing standards of the PCAOB) consisting of a review of the latest available financial statements of the MHC and the Bank, a reading of the minutes of the meetings of the Board
of Directors and Audit Committee of the Primary Parties and consultations with officers of the Primary Parties responsible for financial and accounting matters, nothing came to their attention which caused them to believe that: (A) at
July 31, 2008, there was any increase in non-performing assets, non-performing loans or total debt (defined as advances from the FHLB of Boston, securities sold under agreements to repurchase and subordinated deferrable interest debentures) or
decreases in consolidated total assets, deposits, allowance for loan losses or retained earnings as compared with amounts at April 30, 2008; and during the period from May 1, 2008 to July 31, 2008 there were any decreases, as compared
to the corresponding period in the preceding year, in consolidated net income, non-interest income, tax expense, net interest income, net interest income after provision for loan losses, or increases in provisions for loan losses, non-interest
expense or net income (loss), in each case, except as set forth therein; or (B) during the period from the date of the Recent Developments information included in the Prospectus to a date not more than three business days prior to the date of
the Prospectus there was any increase in non-performing loans, total debt (defined as advances from the FHLB of Boston, securities sold under agreements to repurchase and subordinated deferrable interest debentures) of the Bank or decrease in
consolidated total assets, deposits, or allowance for loan losses of the Bank; at August 31, 2008, there was any increase in classified loans or special mention loans as compared with amounts at April 30, 2008; and during the period from
May 1, 2008 to August 31, 2008 there was any decrease in net income, non-interest income, tax expense, consolidated net interest income, net interest income after provision for loan losses or provision for loan losses of the Bank, in each
case, except as disclosed therein; and (iii) stating that, in addition to the audit examination referred to in its opinion included in the Prospectus and the performance of the procedures referred to in clause (ii) of this subsection (c),
they have compared with the general accounting records of the MHC and the Bank, which are subject to the internal controls of the accounting system of the MHC and the Bank, respectively, and other data prepared by the MHC and the Bank directly from
such accounting records, to the extent specified in such letter, such amounts and/or percentages set forth in the Prospectus as Agent may reasonably request, and they have found such amounts and percentages to be in agreement therewith (subject to
rounding). 
 (d) As soon as practicable following the date hereof, and in no event later than September 18, 2008, Agent shall have
received a supplemental letter from KPMG, LLP dated as 

  

 25 








 
of such date and addressed to the Agent, (i) confirming that the review of the financial statements as of and for the period ended July 31, 2008
has been completed in accordance with Statement of Auditing Standards No. 100, Interim Financial Information (the “SAS 100 Review”) and (ii) stating in effect that, on the basis of the SAS 100 Review, a reading of the minutes of
the meetings of the Board of Directors and Audit Committee of the Primary Parties and consultations with officers of the Primary Parties responsible for financial and accounting matters, nothing came to their attention which caused them to believe
that such unaudited financial statements and financial information included in the section titled “Recent Developments” in the Prospectus are not in conformity with GAAP applied on a basis substantially consistent with that of the audited
financial statements included in the Prospectus. 
 (e) At the Closing Time, Agent shall receive a letter from KPMG LLP dated the Closing
Time, addressed to Agent, confirming the statements made by its letter delivered by it pursuant to Sections 10(c) and (d), the “specified date” referred to in Section 10(c)(ii)(B) to be a date specified in such letter, which shall not
be more than three business days prior to the Closing Time. 
 (f) At the Closing Time, counsel to Agent shall have been furnished with such
documents and opinions as counsel for the Agent may require for the purpose of enabling them to advise Agent with respect to the issuance and sale of the Common Stock as herein contemplated and related proceedings, or in order to evidence the
accuracy of any of the representations and warranties, or the fulfillment of any of the conditions herein contained. 
 (g) At the Closing
Time, the Agent shall receive a certificate of the Chief Executive Officer and Chief Financial Officer of each of the Primary Parties, dated the Closing Time, to the effect that: (i) they have examined the Prospectus and the Registration
Statement and at the time the Prospectus became authorized for final use, the Prospectus and the Registration Statement did not contain 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 under which they were made, not misleading; (ii) there has not been, since the respective dates as of which information is given in the Prospectus, any Material Adverse Effect other than as set forth
or contemplated in the Registration Statement; (iii) the representations and warranties contained in Section 6 of this Agreement are true and correct with the same force and effect as though made at and as of the Closing Time;

Section 10; (v) no stop order has been issued or, to their knowledge, is threatened, by the Commission or any other governmental body; (vi) no order suspending the Offerings, the Conversion, the acquisition of all of the shares of the
Bank by the Holding Company, the transactions required under the Plan to consummate the Conversion or the effectiveness of the Registration Statement has been issued and to their knowledge, no proceedings for any such purpose have been initiated or
threatened by the Division, the FRB, the FDIC, the Commission, or any other federal or state authority; (vii) to their knowledge, no person has sought to obtain regulatory or judicial review of the action of the Division in approving the Plan
or to enjoin the Conversion or the Offerings. 
  

 26 








 (h) At the Closing Time, the Agent shall receive a letter from RP Financial, LC, dated as of the Closing
Time, (i) confirming that said firm is independent of the Primary Parties and is experienced and expert in the area of corporate appraisals within the meaning of the Conversion Regulations, (ii) stating in effect that the Appraisal
complies in all material respects with the applicable requirements of the Conversion Regulations, and (iii) further stating that its opinion of the aggregate pro forma market value of the Primary Parties, as converted, expressed in the
Appraisal as most recently updated, remains in effect. 
 (i) Prior to and at the Closing Time, none of the Primary Parties shall have
sustained, since the date of the latest financial statements included in the Registration Statement and Prospectus, any material loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by
insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth in the Registration Statement and the Prospectus, and since the respective dates as of which information is given in the Registration
Statement and the Prospectus, there shall not have been any material change, or any development involving a prospective material change in, or affecting the general affairs of, management, financial position, retained earnings, long-term debt,
stockholders’ equity or results of operations of any of the Primary Parties, otherwise than as set forth or contemplated in the Registration Statement and the Prospectus, the effect of which, in any such case described above, in the
Agent’s reasonable judgment, is sufficiently material and adverse as to make it impracticable or inadvisable to proceed with the Offerings or the delivery of the Shares on the terms and in the manner contemplated in the Prospectus. 

(j) Prior to and at the Closing Time: (i) in the reasonable opinion of the Agent there shall have been no Material Adverse Effect from and as of
the latest date as of which such condition is set forth in the Prospectus, except as referred to therein; (ii) there shall have been no material transaction entered into by the Primary Parties, independently or considered as one enterprise,
from the latest date as of which the financial condition of the Primary Parties is set forth in the Prospectus, other than transactions referred to or contemplated therein; (iii) none of the Primary Parties shall have received from the
Division, the FRB or the FDIC any direction (oral or written) to make any material change in the method of conducting their business with which it has not complied in all material respects (which direction, if any, shall have been disclosed to the
Agent) and which would reasonably be expected to have a Material Adverse Effect; (iv) none of the Primary Parties shall have been in default (nor shall an event have occurred which, with notice or lapse of time or both, would constitute a
default) under any provision of any agreement or instrument relating to any material outstanding indebtedness; (v) no action, suit or proceeding, at law or in equity or before or by any federal or state commission, board or other administrative
agency, shall be pending or, to the knowledge of the Primary Parties, threatened against any of the Primary Parties or affecting any of their properties wherein an unfavorable decision, ruling or finding would reasonably be expected to have a
Material Adverse Effect; and (vi) the Shares shall have been qualified or registered for offering and sale under the securities or “blue sky” laws of the jurisdictions requested by the Agent. 
 (k) At or prior to the Closing Date, the Agent shall receive (i) a copy of the letter(s) from the Division approving the Conversion Application and
the Information Statement, (ii) a copy of the letter of non–objection from the FDIC with respect to the Conversion, (iii) a 

  

 27 








 
copy of the letter from the FRB approving the BHC Application, (iv) a copy of the letter from the FDIC approving the Merger Application, (v) a copy
of the order from the Commission declaring the Registration Statement effective, (vi) copies of certificates of existence for each of the Primary Parties, or other writing from the Secretary of State of the State of Maryland, the Secretary of
State of the Commonwealth of Massachusetts or the Division in form and substance reasonably satisfactory to the Agent evidencing the valid existence of the Holding Company and the Bank as of the Closing Date, (vi) a certificate from the FDIC
evidencing the Bank’s insurance of accounts, (vii) a certificate of the FHLB of Boston evidencing the Bank’s membership therein, and (viii) any other documents that Agent shall reasonably request. 
 (l) Subsequent to the date hereof, there shall not have occurred any of the following: (i) a suspension or limitation in trading in securities
generally on the New York Stock Exchange or American Stock Exchange or in the over-the-counter market, or quotations halted generally on the Nasdaq Stock Market, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices
for securities have been required by either of such exchanges or FINRA or by order of the Commission or any other governmental authority other than temporary trading halts or limitation (A) imposed as a result of intraday changes in the Dow
Jones Industrial Average, (B) lasting no longer than until the regularly scheduled commencement of trading on the next succeeding business-day, and (C) which, when combined with all other such halts occurring during the previous five
business days, total less than three; (ii) a general moratorium on the operations of commercial banks or other federally-insured financial institutions or general moratorium on the withdrawal of deposits from commercial banks or other
federally-insured financial institutions declared by either federal or state authorities; (iii) any material adverse change in the financial markets in the United States or elsewhere; or (iv) any outbreak of hostilities or escalation
thereof or other calamity or crisis, including, without limitation, terrorist activities after the date hereof, the effect of any of (i) through (iv) herein, in the judgment of the Agent, is so material and adverse as to make it
impracticable to market the Shares or to enforce contracts, including subscriptions or purchase orders, for the sale of the Shares. 
 (m)
All such opinions, certificates, letters and documents will be in compliance with the provisions hereof only if they are reasonably satisfactory in form and substance to the Agent and of counsel for the Agent. Any certificate signed by an officer of
the Primary Parties and delivered to the Agent or to counsel for the Agent shall be deemed a representation and warranty by such Primary Party, as the case may be, to the Agent as to the statements made therein. If any condition to the Agent’s
obligations hereunder to be fulfilled prior to or at the Closing Time is not fulfilled, the Agent may terminate this Agreement (provided that if this Agreement is so terminated but the sale of Shares is nevertheless consummated, the Agent shall be
entitled to the full compensation provided for in Section 4 hereof) or, if the Agent so elects, may waive any such conditions which have not been fulfilled or may extend the time of their fulfillment. 
 Section 11. Indemnification. 
 (a) The Primary Parties jointly and severally agree to indemnify and hold harmless the Agent, its officers, directors, agents, attorneys, servants and employees and each 

  

 28 








 
person, if any, who controls the Agent within the meaning of Section 15 of the 1933 Act or Section 20(a) of the 1934 Act, against any and all loss,
liability, claim, damage or expense whatsoever (including but not limited to settlement expenses, subject to the limitation set forth in the last sentence of paragraph (c) below), joint or several, that the Agent or any of such officers,
directors, agents, attorneys, servants, employees and controlling Persons (collectively, the “Related Persons”) may suffer or to which the Agent or the Related Persons may become subject under all applicable federal and state laws or
otherwise, and to promptly reimburse the Agent and any Related Persons upon written demand for any reasonable expenses (including reasonable fees and disbursements of counsel) incurred by the Agent or any Related Persons in connection with
investigating, preparing or defending any actions, proceedings or claims (whether commenced or threatened) to the extent such losses, claims, damages, liabilities or actions: (i) arise out of or are based upon any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement (or any amendment or supplement thereto), preliminary or final Prospectus (or any amendment or supplement thereto), Issuer Represented Free Writing Prospectus, the
Applications, the Information Statement or any blue sky application or other instrument or document of the Primary Parties or based upon written information supplied by any of the Primary Parties filed in any state or jurisdiction to register or
qualify any or all of the Shares under the securities laws thereof (collectively, the “Blue Sky Applications”), or any application or other document, advertisement, or communication (“Sales Information”) prepared, made or
executed by or on behalf of any of the Primary Parties with its consent or based upon written information furnished by or on behalf of any of the Primary Parties, whether or not filed in any jurisdiction in order to qualify or register the Shares
under the securities laws thereof, (ii) arise out of or are based upon the omission or alleged omission to state in any of the foregoing documents or information, a material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not misleading; (iii) arise from any theory of liability whatsoever relating to or arising from or based upon the Registration Statement (or any amendment or supplement
thereto), preliminary or final Prospectus (or any amendment or supplement thereto), Issuer Represented Free Writing Prospectus, the Applications, the Information Statement, any Blue Sky Applications or Sales Information or other documentation
distributed in connection with the Conversion; or (iv) result from any claims made with respect to the accuracy, reliability and completeness of the records of Eligible Account Holders, Supplemental Eligible Account Holders and Bank
Participants or for any denial or reduction of a subscription or order to purchase Common Stock, whether as a result of a properly calculated allocation pursuant to the Plan or otherwise, based upon such records; provided, however, that no
indemnification is required under this paragraph (a) to the extent such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue material statements or alleged untrue material statements in, or material omission
or alleged material omission from, the Registration Statement (or any amendment or supplement thereto) or the preliminary or final Prospectus (or any amendment or supplement thereto), Issuer Represented Free Writing Prospectus, the Applications, the
Information Statement, the Blue Sky Applications or Sales Information or other documentation distributed in connection with the Conversion made in reliance upon and in conformity with written information furnished to the Primary Parties by the Agent
or its representatives (including counsel) with respect to the Agent expressly for use in the Registration Statement (or any amendment or supplement thereto) or Prospectus (or any amendment or supplement thereto) under the captions “Market for
the Common Stock” and “The Conversion and Offering—Plan of Distribution; Selling Agent Compensation,” or for use in the 

  

 29 








 
Applications, Blue Sky Applications or Sales Information, except for information derived from the Prospectus. Provided further, that the Primary Parties will
not be responsible for any loss, liability, claim, damage or expense to the extent they result primarily from material oral misstatements by the Agent to a purchaser of Shares which are not based upon information in the Registration Statement or
Prospectus, or from actions taken or omitted to be taken by the Agent in bad faith or from the Agent’s gross negligence or willful misconduct, and the Agent agrees to repay to the Primary Parties any amounts advanced to it by the Primary
Parties in connection with matters as to which it is found in a final judgment by a court of competent jurisdiction not to be entitled to indemnification hereunder. 
 (b) The Agent agrees to indemnify and hold harmless the Primary Parties, their directors and officers, agents, servants and employees and each person, if any, who controls any of the Primary Parties within the meaning
of Section 15 of the 1933 Act or Section 20(a) of the 1934 Act against any and all loss, liability, claim, damage or expense whatsoever (including but not limited to settlement expenses, subject to the limitation set forth in the last
sentence of paragraph (c) below), joint or several which they, or any of them, may suffer or to which they, or any of them, may become subject under all applicable federal and state laws or otherwise, and to promptly reimburse the Primary
Parties and any such persons upon written demand for any reasonable expenses (including fees and disbursements of counsel) incurred by them in connection with investigating, preparing or defending any actions, proceedings or claims (whether
commenced or threatened) to the extent such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment
of supplement thereto), the Applications or any Blue Sky Applications or Sales Information or are based upon the omission or alleged omission to state in any of the foregoing documents a material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Agent’s obligations under this Section 11(b) shall exist only if and only to the extent that such untrue
statement or alleged untrue statement was made in, or such material fact or alleged material fact was omitted from, the Registration Statement (or any amendment or supplement thereto) or the Prospectus (or any amendment or supplement thereto) or the
Applications, Blue Sky Applications or Sales Information in reliance upon and in conformity with written information furnished to the Primary Parties by the Agent or its representatives (including counsel) expressly for use therein, and with respect
to the Registration Statement and Prospectus, under the captions “Market for the Common Stock” and “The Conversion and Offering—Plan of Distribution; Selling Agent Compensation” 
 (c) Each indemnified party shall give prompt written notice to each indemnifying party of any action, proceeding, claim (whether commenced or
threatened), or suit instituted against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve it from any liability which it may have on account of this Section 11,
Section 12 or otherwise. An indemnifying party may participate at its own expense in the defense of such action. In addition, if it so elects within a reasonable time after receipt of such notice, an indemnifying party, jointly with any other
indemnifying parties receiving such notice, may assume defense of such action with counsel chosen by it and approved by the indemnified parties that are defendants in such action, unless such indemnified 

  

 30 








 
parties reasonably object to such assumption on the ground that there may be legal defenses available to them that are different from or in addition to those
available to such indemnifying party. If an indemnifying party assumes the defense of such action, the indemnifying parties shall not be liable for any fees and expenses of counsel for the indemnified parties incurred thereafter in connection with
such action, proceeding or claim, other than reasonable costs of investigation. In no event shall the indemnifying parties be liable for the fees and expenses of more than one separate firm of attorneys (unless an indemnified party or parties shall
have reasonably concluded that there may be defenses available to it or them which are different from or in addition to those of other indemnified parties) for all indemnified parties in connection with any one action, proceeding or claim or
separate but similar or related actions, proceedings or claims in the same jurisdiction arising out of the same general allegations or circumstances. The Holding Company shall be liable for any settlement of any claim against the Agent (or its
directors, officers, employees, affiliates or controlling persons), made with the Holding Company’s consent, which consent shall not be unreasonably withheld. The Holding Company shall not, without the written consent of the Agent, settle or
compromise any claim against it based upon circumstances giving rise to an indemnification claim against the Holding Company hereunder unless such settlement or compromise provides that the Agent and the other indemnified parties shall be
unconditionally and irrevocably released from all liability in respect of such claim. 
 (d) The agreements contained in this Section 11
and in Section 12 hereof and the representations and warranties of the Primary Parties set forth in this Agreement shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of the Agent or
its officers, directors, controlling persons, agents, servants, attorneys or employees or by or on behalf of any of the Primary Parties or any officers, directors, controlling persons, agents, servants, attorneys or employees of any of the Primary
Parties; (ii) delivery of and payment hereunder for the Shares; or (iii) any termination of this Agreement. To the extent required by law, Sections 11 and 12 hereof are subject to and limited by Section 23A of the Federal Reserve Act
and Regulation W as promulgated thereunder. 
 Section 12. Contribution. 
 (a) In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in Section 11 is due in
accordance with its terms but is found in a final judgment by a court to be unavailable from the Primary Parties or the Agent, the Primary Parties and the Agent shall contribute to the aggregate losses, claims, damages and liabilities of the nature
contemplated by such indemnification in such proportion so that (i) the Agent is responsible for that portion represented by the percentage that the fees paid to the Agent pursuant to Section 4 of this Agreement (not including expenses)
(“Agent’s Fees”), less any portion of Agent’s Fees paid by Agent to Assisting Brokers, bear to the total proceeds received by the Primary Parties from the sale of the Shares in the Offerings, net of all expenses of the Offerings
except Agent’s Fees, and (ii) the Primary Parties shall be responsible for the balance. If, however, the allocation provided above is not permitted by applicable law or if the indemnified party failed to give the notice required under
Section 11 above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative fault of the Primary Parties on 

  

 31 








 
the one hand and the Agent on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or
actions, proceedings or claims in respect thereof), but also the relative benefits received by the Primary Parties on the one hand and the Agent on the other from the Offerings, as well as any other relevant equitable considerations. The relative
benefits received by the Primary Parties on the one hand and the Agent on the other hand shall be deemed to be in the same proportion as the total proceeds from the Offerings, net of all expenses of the Offerings except Agent’s Fees, received
by the Primary Parties bear, with respect to the Agent, to the total fees (not including expenses) received by the Agent less the portion of such fees paid by the Agent to Assisting Brokers. The relative fault shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Primary Parties on the one hand or the Agent on the other and
the parties relative intent, good faith, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Primary Parties and the Agent agree that it would not be just and equitable if contribution pursuant to
this Section 12 were determined by pro-rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 12. The amount paid or payable by an indemnified
party as a result of the losses, claims, damages or liabilities (or action, proceedings or claims in respect thereof) referred to above in this Section 12 shall be deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action, proceeding or claim. It is expressly agreed that the Agent shall not be liable for any loss, liability, claim, damage or expense or be required to contribute any amount
which in the aggregate exceeds the amount paid (excluding reimbursable expenses) to the Agent under this Agreement less the portion of such fees paid by the Agent to Assisting Brokers. It is understood and agreed that the above-stated limitation on
the Agent’s liability is essential to the Agent and that the Agent would not have entered into this Agreement if such limitation had not been agreed to by the parties to this Agreement. No person found guilty of any fraudulent misrepresentation
(within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not found guilty of such fraudulent misrepresentation. The duties, obligations and liabilities of the Primary Parties and the Agent
under this Section 12 and under Section 11 shall be in addition to any duties, obligations and liabilities which the Primary Parties and the Agent may otherwise have. For purposes of this Section 12, each of the Agent’s and the
Primary Parties’ officers and directors and each person, if any, who controls the Agent or any of the Primary Parties within the meaning of the 1933 Act and the 1934 Act shall have the same rights to contribution as the Primary Parties and the
Agent. Any party entitled to contribution, promptly after receipt of notice of commencement of any action, suit, claim or proceeding against such party in respect of which a claim for contribution may be made against another party under this
Section 12, will notify such party from whom contribution may be sought, but the omission to so notify such party shall not relieve the party from whom contribution may be sought from any other obligation it may have hereunder or otherwise than
under this Section 12. 
 Section 13. Survival. All representations, warranties and indemnities and other statements
contained in this Agreement, or contained in certificates of officers of the Primary Parties or the Agent submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any termination or cancellation of this Agreement
or any investigation made 

  

 32 








 
by or on behalf of the Agent or its controlling persons, or by or on behalf of the Primary Parties and shall survive the issuance of the Shares, and any
legal representative, successor or assign of the Agent, any of the Primary Parties, and any indemnified person shall be entitled to the benefit of the respective agreements, indemnities, warranties and representations. 
 Section 14. Termination. Agent may terminate this Agreement by giving the notice indicated below in this Section at any time after
this Agreement becomes effective as follows: 
 (a) In the event (i) the Plan is abandoned or terminated by the Holding Company;
(ii) the Holding Company fails to consummate the sale of the minimum number of Shares prior to December 31, 2009 in accordance with the provisions of the Plan or as required by the Conversion Regulations and applicable law; (iii) the
Agent terminates this relationship because there has been a Material Adverse Effect since the date of the latest financial statements included in the Prospectus; or (iv) immediately prior to commencement of the Offerings, the Agent terminates
this relationship because in its opinion, which shall have been formed in good faith after reasonable determination and consideration of all relevant factors, there has been a failure to satisfactorily disclose all relevant information in the
Prospectus or the existence of market conditions which might render the sale of the Shares inadvisable, this Agreement shall terminate and no party to this Agreement shall have any obligation to the other hereunder except as set forth in Sections 3,
4, 9, 11 and 12 hereof. 
 (b) If any of the conditions specified in Section 10 shall not have been fulfilled when and as required by
this Agreement, or by the Closing Time, or waived in writing by the Agent, this Agreement and all of the Agent’s obligations hereunder may be canceled by the Agent by notifying the Holding Company of such cancellation in writing at any time at
or prior to the Closing Time, and any such cancellation shall be without liability of any party to any other party except as otherwise provided in Sections 3, 4, 9, 11 and 12 hereof. 
 (c) If Agent elects to terminate this Agreement as provided in this Section, the Holding Company shall be notified by the Agent as provided in
Section 15 hereof. 
 (d) If this Agreement is terminated in accordance with the provisions of Sections 3, 10, or 14, the Primary
Parties shall pay the Agent the fees earned pursuant to Section 4 and will reimburse the Agent for its reasonable expenses pursuant to Section 9, including without limitation accounting, communication, legal and travel expenses.

 EXHIBIT B 
 ASSISTING BROKERS AGREEMENT 
  

 B-1 








                     , 2008 
 Stifel,
Nicolaus & Company, Incorporated 
 650 Madison Avenue 
 10th Floor 
 New York, New York 10022 
 Gentlemen:

 (1) General. We understand that Stifel, Nicolaus & Company, Incorporated (“Stifel”) is entering into this
Agreement with us and other firms who may be offered the right to purchase as principal a portion of securities being distributed to the public. The terms and conditions of this Agreement shall be applicable to any public offering of securities
(“Securities”) pursuant to a registration statement filed under the Securities Act of 1933 (the “Securities Act”) or exempt from registration thereunder (other than a public offering of Securities effected wholly outside the
United States of America), wherein Stifel (acting for its own account or for the account of any underwriting or similar group or syndicate) is responsible for managing or otherwise implementing the sale of the Securities to selected dealers
(“Selected Dealers”) and has informed us that such terms and conditions shall be applicable. Any such offering of Securities to us as a Selected Dealer is hereinafter called an “Offering.” In the case of any Offering in which you
are acting for the account of any underwriting or similar group or syndicate (“Underwriters”), the terms and conditions of this Agreement shall be for the benefit of, and binding upon, such Underwriters, including, in the case of any
Offering in which you are acting with others as representatives of Underwriters, such other representatives. The term “preliminary prospectus” means any preliminary prospectus relating to an Offering of Securities or any preliminary
prospectus supplement together with a prospectus relating to an Offering of Securities; the term “Prospectus” means the prospectus, together with the final prospectus supplement, if any, relating to an Offering of Securities, filed
pursuant to Rule 424(b) or Rule 424(c) under the Securities Act or any successor or similar rules. 
 This Agreement constitutes the entire
agreement of the parties with regard to the subject matter hereof and supersedes any prior oral or written agreements or understanding between the parties hereto or their predecessors with respect to the subject matter hereof. 
 (2) Conditions of Offering, Acceptance and Purchase. Any Offering will be subject to delivery of the Securities and their acceptance by you and
any other Underwriters, may be subject to the approval of all legal matters by counsel and the satisfaction of other conditions, and may be made on the basis of reservation of Securities or an allotment against subscription. You will advise us by
telegram, telex, facsimile, e-mail, or other form of written communication (“Written Communication”) of the particular method and supplementary terms and conditions (including, without limitation, the information as to prices and offering
date referred to in Section 3(c)) of any Offering in which we are invited to participate. To the extent such supplementary terms and conditions are inconsistent with any provision herein, such terms and conditions shall supersede any such
provision. Unless otherwise indicated in any such Written Communication, acceptances and 

  

 B-2 








 
other communications by us with respect to any Offering should be sent to Stifel. You may close the subscription books at any time in your sole discretion
without notice, and you reserve the right to reject any acceptance in whole or in part. Payment for Securities purchased by us is to be made at such office as you may designate, at the public offering price, or, if you shall so advise us, at such
price less the concession to dealers or at the price set forth or indicated in a Written Communication, on such date as you shall determine, on one day’s prior notice to us, by wire transfer to a Stifel account, against delivery of certificates
or other forms evidencing such Securities. If payment is made for Securities purchased by us at the public offering price, the concession to which we shall be entitled will be paid to us upon termination of the provisions of Section 3(c) with
respect to such Securities. 
 Unless we promptly give you written instructions otherwise, if transactions in the Securities may be settled
through the facilities of The Depository Trust Company, delivery of Securities purchased by us will be made through such facilities if we are a member, or if we are not a member, settlement may be made through our ordinary correspondent who is a
member. 
 (3) Representations, Warranties, and Agreements. 
 (a) Registered Offering. In the case of any Offering of Securities that are registered under the Securities Act (“Registered Offering”),
you shall provide us with such number of copies of each preliminary prospectus, the Prospectus and any supplement thereto relating to each Registered Offering as we may reasonably request for the purposes contemplated by the Securities Act and the
Securities Exchange Act of 1934 (the “Exchange Act”) and the applicable Rules and regulations of the Securities and Exchange Commission thereunder. We represent that we are familiar with Rule 15c2-8 under the Exchange Act relating to the
distribution of preliminary and final prospectuses and agree that we will comply therewith. We agree to keep an accurate record of our distribution (including dates, number of copies, and persons to whom sent) of copies of the Prospectus or any
preliminary prospectus (or any amendment or supplement to any thereof), and promptly upon request by you, to bring all subsequent changes to the attention of anyone to whom such material shall have been furnished. We agree to furnish to persons who
receive a confirmation of sale a copy of the Prospectus filed pursuant to Rule 424(b) or Rule 424(c) under the Securities Act. We agree that in purchasing Securities in a Registered Offering we will rely upon no statements whatsoever, written or
oral, other than the statements in the Prospectus delivered to us by you. We will not be authorized by the issuer or other seller of Securities offered pursuant to a Prospectus or by any Underwriter to give any information or to make any
representation not contained in the Prospectus in connection with the sale of such Securities. We will not use any free writing prospectus, unless consented to by you or authorized expressly in writing to you by the issuer in the Registered
Offering. 
 (b) Offering Pursuant to Offering Circular. In the case of any Offering of Securities, other than a Registered Offering,
which is made pursuant to an offering circular or other document comparable to a prospectus in a Registered Offering, including, without limitation, an Offering of “exempted securities” as defined in Section 3(a)(2) of the Securities
Act (an “Exempted Securities Offering”), you shall provide us with such number of copies of each preliminary offering circular, the final offering circular and any supplement thereto relating to each Offering as we may reasonably request.
We agree that we will comply with the applicable federal and state laws, and the applicable rules and regulations of any regulatory body promulgated thereunder, governing the use 

  

 B-3 








 
and distribution of offering circulars by brokers or dealers. We agree that in purchasing Securities pursuant to an offering circular we will rely upon no
statements whatsoever, written or oral, other than the statements in the final offering circular delivered to us by you. We will not be authorized by the issuer or other seller of Securities offered pursuant to an offering circular or by any
Underwriter to give any information or to make any representation not contained in the offering circular in connection with the sale of such Securities. 
 (c) Offer and Sale to the Public. With respect to any Offering of Securities, you will inform us by a Written Communication of the public offering price, the selling concession, the reallowance (if any) to
dealers, and the time when we may commence selling Securities to the public. After such public offering has commenced, you may change the public offering price, the selling concession, and the reallowance to dealers. With respect to each Offering of
Securities, until the provisions of this Section 3(c) shall be terminated pursuant to Section 5, we agree to offer Securities to the public only at the public offering price, except that if a reallowance is in effect, a reallowance from
the public offering price not in excess of such reallowance may be allowed as consideration for services rendered in distribution to dealers who are actually engaged in the investment banking or securities business, who execute the written agreement
prescribed by Rule 2740 of the Rules of Conduct of the Financial Industry Regulatory Authority (the “FINRA”) and who are either members in good standing of the FINRA or foreign brokers or dealers not eligible for membership in the FINRA
who represent to us that they will promptly reoffer such Securities at the public offering price and will abide by the conditions with respect to foreign brokers and dealers set forth in Section 3(f) hereof. 
 (d) Stabilization and Overallotment. You may, with respect to any Offering, be authorized to over-allot in arranging sales to Selected Dealers, to
purchase and sell Securities, any other securities of the issuer of the Securities of the same class and series and any other securities of such issuer that you may designate for long or short account, and to stabilize or maintain the market price
of the Securities. We agree not to purchase and sell Securities for which an order from a client has not been received without your consent in each instance. We agree to advise you from time to time upon request, prior to the termination of the
provisions of Section 3(c) with respect to any Offering, of the amount of Securities purchased by us hereunder remaining unsold and we will, upon your request, sell to you, for the accounts of the Underwriters, such amount of Securities as you
may designate, at the public offering price thereof less an amount to be determined by you not in excess of the concession to dealers. In the event that prior to the later of (i) the termination of the provisions of Section 3(c) with
respect to any Offering, or (ii) the covering by you of any short position created by you in connection with such Offering for your account or the account of one or more Underwriters, you purchase or contract to purchase for the account of any
of the Underwriters, in the open market or otherwise, any Securities theretofore delivered to us, you reserve the right to withhold the above-mentioned concession to dealers on such Securities if sold to us at the public offering price, or if such
concession has been allowed to us through our purchase at a net price, we agree to repay such concession upon your demand, plus in each case any taxes on redelivery, commissions, accrued interest, and dividends paid in connection with such purchase
or contract to purchase. 
 (e) Open Market Transactions. We agree to abide by Regulation M under the Exchange Act and we agree not to
bid for, purchase, attempt to purchase, or sell, directly or indirectly, any Securities, any other Reference Securities (as defined in Regulation M) of the issuer, or any other 

  

 B-4 








 
securities of such issuer as you may designate, except as brokers pursuant to unsolicited orders and as otherwise provided in this Agreement. If the
Securities are common stock or securities convertible into common stock, we agree not to effect, or attempt to induce others to effect, directly or indirectly, any transactions in or relating to any stock of such issuer, except to the extent
permitted by Rule 101 of Regulation M under the Exchange Act. 
 (f) FINRA. We represent that we are actually engaged in the
investment banking or securities business and we are either (i) a member in good standing of the FINRA, (ii) if not such a member, a foreign dealer not eligible for membership, or (iii) solely in connection with an Exempted Securities
Offering, a bank, as defined in Section 3(a)(6) of the Exchange Act, that does not otherwise fall within provision (i) or (ii) of this sentence (a “Bank”). If we are a member as described in (i), we agree that in making
sales of the Securities we will comply with all applicable interpretative materials and Conduct Rules of the FINRA, including, without limitation, Conduct Rules 2740 (relating to Selling Concessions, Discounts and Other Allowances) and 2790
(relating to New Issues). If we are a foreign dealer as described in (ii), we agree not to offer or sell any Securities in the United States of America, its territories or its possessions or to persons who are citizens thereof or residents therein
(other than through you), and in making sales of Securities outside the United States of America we agree to comply as though we were a member with Conduct Rules 2730 (relating to Securities Taken in Trade), 2740 (relating to Selling Concessions),
2750 (relating to Transactions with Related Persons) and 2790 (relating to New Issues) as though we were such a member and to comply with Conduct Rule 2420 (relating to Dealing with Non-Members) as it applies to a nonmember broker or dealer in a
foreign country. In connection with an Exempted Securities Offering, if we are a Bank, we agree to also comply, as though we were an FINRA member, with the provision of Rules 2730, 2740 and 2750 of the Conduct Rules. We further represent, by our
participating in an Offering, that we have provided to you all documents and other information required to be filed with respect to us, any related person or any person associated with us or any such related person pursuant to the supplementary
requirements of the FINRA’s interpretation with respect to review of corporate financing as such requirements relate to such Offering. 
 We further agree that, in connection with any purchase of Securities from you that is not otherwise covered by the terms of this Agreement (whether you are acting as manager, as member of an underwriting syndicate or a selling group or
otherwise), if a selling concession, discount or other allowance is granted to us, the preceding paragraph will be applicable. 
 (g)
Relationship among Underwriters and Selected Dealers. You may buy Securities from or sell Securities to any Underwriter or Selected Dealer and, with your consent, the Underwriters (if any) and the Selected Dealers may purchase Securities from
and sell Securities to each other at the public offering price less all or any part of the concession. We are not authorized to act as agent for you or any Underwriter or the issuer or other seller of any Securities in offering Securities to the
public or otherwise. Nothing contained herein or in any Written Communication from you shall constitute the Selected Dealers partners with you or any Underwriter or with one another. If the Selected Dealers, among themselves or with the
Underwriters, should be deemed to constitute a partnership for federal income tax purposes, then we elect to be excluded from the application of Subchapter K, Chapter 1, Subtitle A of the Internal Revenue Code of 1986 and agree not to take any
position inconsistent with that election. We authorize you, in your discretion, to execute and file on our behalf such evidence of that election as may be required by the Internal 

  

 B-5 








 
Revenue Service. Neither you nor any Underwriter shall be under any obligation to us except for obligations assumed hereby or in any Written Communication
from you in connection with any Offering. In connection with any Offering, we agree to pay our proportionate share of any tax, claim, demand, or liability asserted against us, and the other Selected Dealers or any of them, or against you or the
Underwriters, if any, based on any claim that such Selected Dealers or any of them constitute an association, unincorporated business, or other separate entity, including in each case our proportionate share of any expense incurred in defending
against any such tax, claim, demand, or liability. 
 (h) Blue Sky Laws. Upon application to you, you will inform us as to the
jurisdictions in which you believe the Securities have been qualified for sale or are exempt under the respective securities or “blue sky” laws of such jurisdictions. We understand and agree that compliance with the securities or
“blue sky” laws in each jurisdiction in which we shall offer or sell any of the Securities shall be our sole responsibility and that you assume no responsibility or obligations as to the eligibility of the Securities for sale or our right
to sell the Securities in any jurisdiction. 
 (i) Compliance with Law. We agree that in selling Securities pursuant to any Offering
(which agreement shall also be for the benefit of the issuer or other seller of such Securities), we will comply with the applicable provisions of the Securities Act and the Exchange Act, the applicable Rules and regulations of the Securities and
Exchange Commission thereunder, the applicable Rules and regulations of the FINRA, the applicable Rules and regulations of any securities exchange having jurisdiction over the Offering, and the applicable laws, rules and regulations specified in
Section 3(c) hereof. Without limiting the foregoing, (a) we agree that, at all times since we were invited to participate in an Offering of Securities, we have complied with the provisions of Regulation M applicable to such Offering, in
each case after giving effect to any applicable exemptions and (b) we represent that our incurrence of obligations hereunder in connection with any Offering of Securities will not result in the violation by us of Rule 15c3-1 under the Exchange
Act, if such requirements are applicable to us. You shall have full authority to take such action as you may deem advisable in respect of all matters pertaining to any Offering. Neither you nor any Underwriter shall be under any liability to us,
except for lack of good faith and for obligations expressly assumed by you in this Agreement; provided, however, that nothing in this sentence shall be deemed to relieve you from any liability imposed by the Securities Act. 
 (j) Best Efforts Offering. If you communicate to us that a particular offering is being made on a best efforts basis, then the terms in this
Section 3(j) apply and other inconsistent terms in this Agreement do not apply. 
 (i) The offering will be a best efforts offering. The
offering also will be contingent and involve a closing only after receipt of necessary documentation from the issuer and satisfaction of other conditions, if any, specified in the prospectus or offering circular and the agency or engagement
agreement with you and the issuer. The offering is designed to comply with applicable Commission rules, including Rules 15c2-4, 10b-9, and 15c6-1. See FINRA Notice to Members 98-4, 87-61 and 84-7. 
 (ii) We represent and agree that we shall take necessary steps to comply with Commission Rules 15c2-4, 10b-9 and 15c6-1, including, but not limited to,
depositing funds in a complying special account if funds are received before all closing conditions have been met. We also represent that we are aware that those who purchase in this best efforts offering are subject to the investor purchase
limitations described in the prospectus or offering circular. 
  

 B-6 








 (4) Indemnification. We agree to indemnify and hold harmless Stifel, the issuer of the Securities,
each person, if any, who controls (within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act) Stifel or the issuer of the Securities, and their respective directors, officers and employees from and
against any and all losses, liabilities, costs or claims (or actions in respect thereof) (collectively, “Losses”) to which any of them may become subject (including all reasonable costs of investigating, disputing or defending any such
claim or action), insofar as such Losses arise out of or are in connection with the breach of any representation, warranty or agreement made by us herein. 
 If any claim, demand, action or proceeding (including any governmental investigation) shall be brought or alleged against an indemnified party in respect of which indemnity is to be sought against an indemnifying
party, the indemnified party shall promptly notify the indemnifying party in writing, and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the
indemnified party and any others the indemnified party may designate in such proceeding and shall pay the reasonable fees and expenses of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to
retain its own counsel, but the reasonable 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 retention of such
counsel, (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to such indemnified party or (iii) the named parties to 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 interests between them. It is agreed that the indemnifying party shall not, in
connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate law firm (in addition to local counsel where necessary) for all such indemnified parties. Such
firm shall be designated in writing by the indemnified party. The indemnifying party 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 from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party,
effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding. 
 The indemnity
agreements contained in this Section and the representations and warranties by us in this Agreement shall remain operative and in full force and effect regardless of: (i) any termination of this Agreement, (ii) any investigation made by an
indemnified party or on such party’s behalf or any person controlling an indemnified party or by or on behalf of the indemnifying party, its directors or officers or any person controlling the indemnifying party, and (iii) acceptance of
and payment for any Securities. 
  

 B-7 








 (5) Termination; Supplements and Amendments. This Agreement may be terminated by either party
hereto upon five business days’ written notice to the other party; provided that with respect to any Offering for which a Written Communication was sent and accepted prior to such notice, this Agreement as it applies to such Offering shall
remain in full force and effect and shall terminate with respect to such Offering in accordance with the last sentence of this Section. This Agreement may be supplemented or amended by you by written notice thereof to us, and any such supplement or
amendment to this Agreement shall be effective with respect to any Offering to which this Agreement applies after the date of such supplement or amendment. Each reference to “this Agreement” herein shall, as appropriate, be to this
Agreement as so amended and supplemented. The terms and conditions set forth in Sections 3(c) and (e) with regard to any offering will terminate at the close of business on the thirtieth day after the date of the initial public offering of the
Securities to which such Offering relates, but such terms and conditions, upon notice to us, may be terminated by you at any time. 
 (6)
Successors and Assigns. This Agreement shall be binding on, and inure to the benefit of, the parties hereto and other persons specified or indicated in Section 1, and the respective successors and assigns of each of them. 
 (7) Governing Law. This Agreement and the terms and conditions set forth herein with respect to any Offering together with such supplementary
terms and conditions with respect to such Offering as may be contained in any Written Communication from you to us in connection therewith shall be governed by, and construed in accordance with, the laws of the State of Missouri without regard to
conflicts of laws principles.

any Securities pursuant to an Offering shall constitute (i) acceptance of and agreement to the terms and conditions of this Agreement (as supplemented and amended pursuant to Section 5) together with and subject to any supplementary terms
and conditions contained in any Written Communication from you in connection with such Offering, all of which shall constitute a binding agreement between us and you, individually, or as representative of any Underwriters, (ii) in confirmation
that our representations and warranties set forth in Section 3 are true and correct at that time and (iii) confirmation that our agreements set forth in Sections 2 and 3 have been and will be fully performed by us to the extent and at the
