There are no pending or, to the knowledge of the Company, threatened, claims by or on behalf of any Employee Plan, by any employee or beneficiary covered under any such Employee Plan or by any governmental authority, or otherwise involving such Employee Plans or any of their respective fiduciaries (other than for routine claims for benefits).

(ff) Other than as contemplated by this Agreement, the Company has not incurred any liability for any finder’s or broker’s fee, or agent’s commission in connection with the execution and delivery of this Agreement or the consummation of the transactions contemplated hereby.

(gg) Each of the contracts, agreements and instruments material to the condition (financial or otherwise), earnings or business of the Company and its Bank on a consolidated basis, or listed, described, or attached as an exhibit to the Registration Statement is in full force and effect and is the legal, valid and binding agreement of the Company or the Bank and the other parties thereto, enforceable in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, reorganization or similar laws affecting the rights of creditors generally and subject to general principles of equity. Neither the Company nor the Bank has sent or received any notice indicating the termination of or intention to terminate any of the contracts or agreements referred to or described in the Registration Statement, the Prospectus, or any Permitted Free Writing Prospectus, or filed as an exhibit to the Registration Statement, and no such termination has been threatened by the Company, the Bank or, to the knowledge of the Company, any other party to any such contract or agreement.

12

(hh) No relationship, direct or indirect, exists between or among the Company or the Bank, on the one hand, and the directors, officers, trustees, stockholders, customers or suppliers of the Company or the Bank, on the other hand, which is required to be described in the Registration Statement, the Prospectus, any Preliminary Prospectus or any Permitted Free Writing Prospectus which is not adequately described therein.

(ii) Except as described in the Prospectus and each Preliminary Prospectus, there are no contractual encumbrances or restrictions or requirements or material legal restrictions or requirements required to be described therein, on the ability of the Bank, (A) to pay dividends or make any other distributions on its capital stock or to pay any indebtedness owed to the Company, (B) to make any loans or advances to, or investments in, the Company or (C) to transfer any of its property or assets to the Company. Except as described in the Prospectus and each Preliminary Prospectus, there are no restrictions, encumbrances or requirements affecting the payment of dividends or the making of any other distributions on any of the capital stock of the Company.

(jj) Except as described in the Prospectus and each Preliminary Prospectus and except as would not have, singly or in the aggregate, a Material Adverse Effect, (A) neither the Company nor the Bank is in violation of any federal, state or local statute, law, rule, regulation, ordinance, code, policy or rule of common law or any judicial or administrative interpretation thereof, including any judicial or administrative order, consent, decree or judgment, relating to pollution or protection of human health, the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including, without limitation, laws and regulations relating to the release or threatened release of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum or petroleum products (collectively, “Hazardous Materials”) or to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials (collectively, “Environmental Laws”), (B) the Company and the Bank have all permits, authorizations and approvals required under any applicable Environmental Laws and are each in material compliance with their requirements, (C) there are no pending or, to the knowledge of the Company, threatened administrative, regulatory or judicial actions, suits, demands, demand letters, claims, liens, notices of noncompliance or violation, investigation or proceedings relating to any Environmental Law against the Company or the Bank and (D) there are no events or circumstances known to the Company that could form the basis of an order for clean-up or remediation, or an action, suit or proceeding by any private party or governmental body or agency, against or affecting the Company or the Bank relating to Hazardous Materials or any Environmental Laws. Except as described in the Registration Statement, and the Prospectus and each Preliminary Prospectus or except as would not have, individually or in the aggregate, a Material Adverse Effect, to the Company’s knowledge, none of the property owned or leased by the Company or the Bank or their predecessors is contaminated with any Hazardous Materials, and neither the Company nor the Bank may be deemed an “owner or operator” of a “facility” or “vessel” which owns, possesses, transports, generates or disposes of a “hazardous substance” as those terms are defined in §9601 of the Comprehensive Environmental Response, Compensation and Liability Act of 1980, 42 U.S.C. §9601 et seq.

(kk) The Company and the Bank have properly administered all accounts for which they act as a fiduciary, including but not limited to accounts for which they

13

serve as a trustee, agent, custodian, personal representative, guardian, conservator or investment advisor, in accordance with the terms of the governing documents and applicable state and federal law and regulation and common law, except where the failure to be in compliance would not have, individually or in the aggregate, a Material Adverse Effect. Neither the Company nor the Bank nor any of their directors, officers or employees has committed any material breach of trust with respect to any such fiduciary account, and the accountings for each such fiduciary account are true and correct in all material respects and accurately reflect the assets of such fiduciary account in all material respects.

(ll) No consent, approval, authorization or order of, or qualification with, any governmental body or agency, other than those obtained, is required in connection with the offering of the Affiliate Shares in any jurisdiction where the Affiliate Shares are being offered (except such additional steps as may be required by the Commission, the NASD or such additional steps as may be necessary to qualify the Shares for public offering by the Underwriter under state securities or Blue Sky laws). The Company has not offered, or caused the Underwriter or any of its affiliates to offer, Shares of the Company to any person with the specific intent to unlawfully influence (i) a customer or supplier of the Company in order to alter the customer’s or supplier’s level or type of business with the Company, or (ii) a trade journalist or publication to write or publish favorable information about the Company or its products.

(mm) The Merger Agreement has been duly authorized, executed and delivered by the Company and the Bank, and constitutes a valid, legal, and binding obligation of each of the Company and the Bank, enforceable in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting the rights of creditors generally, and subject to general principles of equity. The execution, delivery and performance of the Merger Agreement by the Company and the Bank and the consummation by the Company and the Bank of the transactions contemplated thereby do not and will not conflict with, result in the creation or imposition of any material lien, claim, charge, encumbrance or restriction upon any property or assets of the Company or the Bank, constitute a breach or violation of, or constitute a default under, with or without notice or lapse of time or both, any of the terms, provisions or conditions of (A) the corporate charter, articles of incorporation, by-laws or other governing documents of the Company or the Bank, (B) any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease, franchise, license, Permit or any other agreement or instrument to which the Company or the Bank is a party or by which any of them or any of their respective properties may be bound, or (C) any order, decree, judgment, rule or regulation of any court, arbitrator, government, or governmental agency or instrumentality, domestic or foreign, having jurisdiction over the Company or the Bank or any of their respective properties which conflict, creation, imposition, breach, violation or default would have, either individually or in the aggregate, a Material Adverse Effect.

(nn) The Registration Statement, the Prospectus, each Preliminary Prospectus and any Permitted Free Writing Prospectus contain all information regarding the Merger Agreement and 1 st Service, as is required to be disclosed therein under the Act and the Rules and Regulations. The information contained in the Registration Statement, the Prospectus, each Preliminary Prospectus and any Permitted Free Writing Prospectus regarding the Merger Agreement and 1 st Service is true and accurate in all material respects, and does not omit to state any material fact necessary to make the statements therein, in light of the circumstances under

14

which they were made, not misleading. The representations and warranties set forth in Articles IV and V of the Merger Agreement and in the schedules referred to Articles IV and V of the Merger Agreement are true, complete and correct and are incorporated by reference herein as a representation and warranty from the Company to the Selling Agent.

(oo) As of the date hereof, the Company is not aware of any developments that make consummation of the transactions contemplated by the Merger Agreement unlikely to occur.

Any certificate signed by any officer of the Company and delivered to the Underwriter or counsel for the Underwriter in connection with the offering of the Shares contemplated hereby shall be deemed a representation and warranty by the Company to the Underwriter and shall be deemed to be a part of this Section 1 and incorporated herein by this reference.

2. APPOINTMENT OF UNDERWRITER; SALE OF THE SHARES. The Company hereby appoints the Underwriter as its sole and exclusive agent for the purpose of selling, in accordance with the terms and conditions hereof, the Shares. The Underwriter hereby accepts such agency and agrees to use its best efforts to sell the Shares on said terms and conditions.

(a) The Underwriter represents and warrants to the Company that:

(i) Underwriter is registered as a broker-dealer with the Commission and is a member of the NASD.

(ii) Underwriter is validly existing as a limited liability company in good standing under the laws of its jurisdiction of formation, with full corporate power and authority to provide the services to be furnished to the Company hereunder.

(iii) The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly and validly authorized by all necessary corporate action on the part of Underwriter, and this Agreement is a legal valid and binding obligation of Underwriter, enforceable in accordance with its terms, except as rights to indemnity hereunder may be limited by federal or state securities laws and except as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting the rights of creditors generally, and subject to general principles of equity.

(iv) Underwriter and each of its employees, agents and representatives who shall perform any of the services required hereunder to be performed by Underwriter shall be duly authorized and shall have all licenses, approvals and permits necessary to perform such services, and Underwriter is a registered broker-dealer in the jurisdictions in which Shares have been offered and will be sold and its employees are duly licensed in such jurisdictions as brokers, dealers, agents, or sales people, as required by such jurisdiction.

(v) Underwriter will not knowingly permit any dealers to offer or re-offer the Shares who do not have all licenses, approvals and permits necessary to perform such services and who are not registered as (or exempt from registration as) dealers with the Commission, the NASD and any jurisdiction in which Shares are offered or re-offered by such dealers.

15

(vi) There is not now pending nor, to Underwriter’s knowledge, threatened against Underwriter any investigation, inquiry, action or proceeding before the Commission, the NASD, any state securities commission or any state or federal court.

(vii) Underwriter will use its best efforts to make the Road Show available without restriction by means of graphic communication to any person, including any potential investor in the Shares, (and if there is more than one version of the Road Show for the Offering that is a written communication, the version available without restriction will be made available no later than the other versions) so that the Company need not comply with the filing requirements of Rules 164 and 433 under the Act.

(viii) Underwriter has received from the NASD a determination of “no objection” with respect to the fairness and reasonableness of the underwriting terms of this Agreement.

(ix) Underwriter has taken all actions necessary to permit the Company to offer and sell the Shares in every jurisdiction of the United States except . Underwriter is not aware of any stop order or similar proceeding for such purpose initiated by the Commission or any securities commission of any jurisdiction of the United States that suspends the effectiveness, disqualifies or revokes an exemption for the legal and proper offer and sale of the Shares in such jurisdiction.

(b) On the basis of the representations, warranties and covenants herein contained, and subject to the conditions herein set forth, the Company agrees to issue and sell up to 2,000,000 Shares in the Offering. All Shares to be offered and sold in the Offering shall be issued and sold through the Underwriter, as agent for the Company, to the public and the Underwriter agrees to use its best efforts to sell the Shares as agent for the Company, at the price per share set forth on the cover page of the final Prospectus for the Offering (the “Offering Price”). In consideration for the Underwriter’s efforts under this Section, the Company agrees to pay the Underwriter a commission (“Selling Commission”) equal to 3.5% of the Offering Price of all Shares sold through the Underwriter in the Offering; provided, however, that no Selling Commission shall be paid with respect to any Affiliate Shares. It shall be the Underwriter’s responsibility to compensate any selected dealers out of the commissions that it receives from the Company. The Underwriter may reject any offer to purchase the Shares made through the Underwriter or a selected dealer in whole or in part (other than the Affiliate Shares), and any such rejection shall not be deemed a breach of the Underwriter’s agreement contained herein. This is strictly a “best efforts” offering and there is no minimum contingency of a specific number of Shares which must be sold prior to proceeding with a Closing. The Company will not sell or agree to sell any of its Shares otherwise than through the Underwriter. In the event the Company or any of its executive officers is contacted directly or indirectly by prospective purchasers of the Shares, the Company will promptly forward the names of such prospective purchasers to the Underwriter.

(c) It is understood that, after the Registration Statement becomes effective, the Underwriter proposes to sell the Shares to the public as agent for the Company upon the

16

terms and conditions set forth in the Prospectus. In addition, the Underwriter shall comply with Rule 15c2-4. Only broker/dealers who are either (i) members in good standing of the National Association of Securities Dealers, Inc. (the “NASD”) that are registered with the NASD and maintain net capital pursuant to Rule 15c3-1 promulgated under the Exchange Act of not less than $25,000 or (ii) dealers with their principal places of business located outside the United States, its territories and its possessions and not registered as brokers or dealers under the Exchange Act, who have agreed not to make any sales within the United States, its territories or its possessions or to persons who are nationals thereof or residents therein shall be designated selected dealers by the Underwriter. The Underwriter shall require all selected dealers to comply with Rule 15c2-4.

3. PAYMENT AND DELIVERY.

Payment for the Shares to be sold in the Offering is to be made by the Underwriter in Federal (same day) funds to an account designated by the Company. Such payment and delivery of such Shares are to be made through the facilities of The Depository Trust Company (“DTC”) at 10:00 a.m., New York time, on the third business day after the date of this Agreement or at such other time and date not later than five business days thereafter as the Underwriter and the Company shall agree upon, such time and date being herein referred to as the “Closing Date.” (As used herein, “business day” means a day on which the New York Stock Exchange is open for trading and on which banks in New York are open for business and not permitted by law or executive order to be closed.). The Company shall deliver payment of the Selling Commission due to the Underwriter by wire transfer or certified or bank cashier’s check drawn to the order of the Underwriter in immediately available funds, to the Underwriter on the Closing Date.

4. COVENANTS OF THE COMPANY.

The Company covenants and agrees with the Underwriter that:

(a) The Company will (i) use its best efforts to cause the Registration Statement to become effective and, if the procedure in Rule 430A of the Rules and Regulations is followed, to prepare and timely file with the Commission under Rule 424(b) of the Rules and Regulations a Prospectus in a form approved by the Underwriter containing information previously omitted at the time of effectiveness of the Registration Statement in reliance on Rule 430A of the Rules and Regulations; (ii) timely file with the Commission under Rule 433 of the Rules and Regulations any Permitted Free Writing Prospectus required to be filed by it under such rule; (iii) not file any amendment to the Registration Statement (including any filing under Rule 462(b)) or supplement to the Prospectus, any Preliminary Prospectus or any Permitted Free Writing Prospectus of which the Underwriter shall not previously have been advised and furnished with a copy or to which the Underwriter shall have reasonably objected in writing or which is not in compliance with the Rules and Regulations; and (iv) file on a timely basis all reports and any definitive proxy or information statements required to be filed by the Company with the Commission subsequent to the date of the Prospectus and prior to the termination of the Offering of the Shares by the Underwriter.

17

stabilization or manipulation of the price of any securities of the Company in violation of the Rules and Regulations, including, but not limited to, Regulation M of the Exchange Act.

(c) The Company will advise the Underwriter promptly (i) when the Registration Statement or any post-effective amendment thereto shall have become effective; (ii) of receipt of any comments from the Commission; (iii) of any request of the Commission for amendment of the Registration Statement or for supplement to the Prospectus, any Preliminary Prospectus or any Permitted Free Writing Prospectus or for any additional information; and (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the use of the Prospectus, any Preliminary Prospectus or any Permitted Free Writing Prospectus or of the institution of any proceedings for that purpose. The Company will use its best efforts to prevent the issuance of any such stop order preventing or suspending the use of the Prospectus and to obtain as soon as possible the lifting thereof, if issued.

(d) The Company will cooperate with the Underwriter in endeavoring to qualify the Shares for sale under the securities laws of such jurisdictions as the Underwriter may reasonably have designated in writing and will make such applications, file such documents, and furnish such information as may be reasonably required for that purpose, provided the Company shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such a consent. The Company will, from time to time, prepare and file such statements, reports, and other documents, as are or may be required to continue such qualifications in effect for so long a period as the Underwriter may reasonably request for distribution of the Shares.

(e) The Company will deliver to, or upon the order of, the Underwriter, from time to time, as many copies of any Preliminary Prospectus as the Underwriter may reasonably request. The Company will deliver to, or upon the order of, the Underwriter during the period when delivery of a Prospectus is required under the Act, as many copies of the Prospectus in final form, or as thereafter amended or supplemented, as the Underwriter may reasonably request. The Company will deliver to the Underwriter at or before the Closing Date, four signed copies of the Registration Statement and all amendments thereto including all exhibits filed therewith, and will deliver to the Underwriter such number of copies of the Registration Statement (including such number of copies of the exhibits filed therewith that may reasonably be requested) and of all amendments thereto, as the Underwriter may reasonably request.

(f) The Company will comply with the Act and the Rules and Regulations, and the Exchange Act, and the rules and regulations of the Commission thereunder, so as to permit the completion of the distribution of the Shares as contemplated in this Agreement and the Prospectus. If during the period in which a prospectus is required by law to be delivered (whether physically or through compliance with Rule 172 of the Rules and Regulations or any similar rule) by the Underwriter or any selected dealer, any event shall occur as a result of which, in the judgment of the Company or in the reasonable opinion of the Underwriter, it becomes necessary to amend or supplement the Prospectus, any Preliminary Prospectus or any Permitted Free Writing Prospectus in order to make the statements therein, in the light of the circumstances existing at the time such document is delivered to a purchaser, not misleading, or, if it is necessary at any time to amend or supplement the Prospectus, any Preliminary Prospectus or any Permitted Free Writing Prospectus to comply with any law, the Company promptly will prepare

18

and file with the Commission an appropriate amendment to the Registration Statement or supplement to the Prospectus, any Preliminary Prospectus or Permitted Free Writing Prospectus so that the document as so amended or supplemented will not, in the light of the circumstances when it is so delivered, be misleading, or so that the document will comply with the law.

(g) The Company will timely file such reports pursuant to the Exchange Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement for the purposes of, and to provide the benefits contemplated by, the last paragraph of Section 11(a) of the Act.

(h) Prior to the Closing Date, the Company will furnish to the Underwriter, as soon as they have been prepared by or are available to the Company, a copy of any unaudited interim financial statements of the Company for any period subsequent to the period covered by the most recent financial statements appearing in the Registration Statement and the Prospectus.

The Underwriter agrees, for the benefit of the selected dealers, if applicable, not to provide such consent without providing notice to the selected dealers to permit compliance with applicable provisions of NASD Conduct Rule 2711(f) restricting publication and distribution of research and public appearances by research analysts before and after the expiration, waiver or termination of a lock-up agreement and agrees only to provide consent in circumstances that will permit such compliance. Notwithstanding the foregoing, in the event that either (i) during the period that begins on the date that is 15 calendar days plus three (3) business days before the last day of the Restricted Period and ends on the last day of the Restricted Period, the Company issues an earnings release or material news or a material event relating to the Company occurs, or (ii) prior to the expiration of the Restricted Period, the Company announces that it will release earnings results during the 16-day period

19

beginning on the last day of the Restricted Period, the restrictions set forth herein will continue to apply until the expiration of the date that is 15 calendar days plus three (3) business days after the date on which the earnings release is issued or the material news or event related to the Company occurs.

(k) The Company has caused each officer and director of the Company to furnish to the Underwriter, on or prior to the date of this Agreement, a letter or letters, in form and substance satisfactory to the Underwriter, pursuant to which each such person shall agree not to offer, sell, sell short or otherwise dispose of any shares of Common Stock of the Company, or any other securities exchangeable or exercisable for Common Stock of the Company or derivative of Common Stock of the Company owned by such person or request the registration for the offer or sale of any of the foregoing (or as to which such person has the right to direct the disposition of) for a period of 180 days after the effective date of the Registration Statement, directly or indirectly, except with the prior written consent of the Underwriter (“Lock-Up Agreements”).

(n) The Company will maintain a transfer agent and, if necessary under the jurisdiction of incorporation of the Company, a registrar for the Common Stock.

(o) Prior to the Closing Date, the Company will not issue any press releases or other communications directly or indirectly and will hold no press conferences with respect to the Company or the Bank, on the financial condition, results of operations, business, properties, assets or liabilities of the Company or the Bank, or the offering of the Shares, without the prior written consent of the Underwriter.

6. CONDITIONS OF OBLIGATIONS OF THE UNDERWRITER.

The obligations of the Underwriter under this Agreement are subject to the accuracy, as of the Closing Date, of the representations and warranties of the Company contained herein, and to the performance by the Company of its covenants and obligations hereunder and to the following additional conditions:

No stop order suspending the effectiveness of the Registration Statement, as amended from time to time, shall have been issued and no proceedings for that purpose shall have been taken or, to the knowledge of the Company, shall be contemplated by the Commission and no injunction, restraining order, or order of any nature by a Federal or state court of competent jurisdiction shall have been issued as of the Closing Date which would prevent the issuance of the Shares. The Registration Statement and all amendments thereto shall not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. None of the Preliminary Prospectuses nor the Prospectus, and no amendment or supplement thereto, shall include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading. None of the Permitted Free Writing Prospectuses, if any, shall include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading.

(b) The Underwriter shall have received on the Closing Date the opinions of Elias, Matz, Tiernan & Herrick, L.L.P., special counsel for the Company, dated the Closing Date, addressed to the Underwriter (and stating that it may be relied upon by Silver, Freedman & Taff, LLP, as special counsel for the Underwriter) to the effect as set forth in Exhibit A-1 hereto.

In rendering such opinion, Elias, Matz, Tiernan & Herrick, L.L.P. may rely (A) as to matters involving the application of any laws other than the laws of the United States, Virginia corporate law or New York law, to the extent such counsel deems proper and specified in such opinion, upon the opinion of counsel licensed to practice in such jurisdiction and (B) as to matters of fact, on certificates of responsible officers of the Company and the Bank and public officials.

Such counsel shall also confirm that, in connection with the preparation of the Registration Statement, the Prospectus, each Preliminary Prospectus and any Permitted Free Writing Prospectus, such counsel has participated in separate conferences with officers and Underwriters of the Company, the Company’s independent public accountants and the Underwriter and its counsel, at which conferences such counsel made inquiries of the Company’s officers, representatives and accountants and discussed in detail the contents of the Registration Statement, Prospectus, each Preliminary Prospectus and any Permitted Free Writing Prospectus. While such counsel has not confirmed the accuracy or completeness or otherwise verified the information contained in the Registration Statement, the Prospectus, any Preliminary Prospectus or any Permitted Free Writing Prospectus or any amendment or supplement thereto, and does not assume any responsibility for such information, except as set forth in such counsel’s opinion, based upon such conferences and a review of corporate records of the Company as such counsel conducted in connection with preparation of the Registration Statement, Prospectus, each Preliminary Prospectus and any Permitted Free Writing Prospectus (relying as to materiality as to factual matters on certificates of officers and other factual representations by the Company), nothing has come to their attention that would lead them to believe (A) that the Registration Statement or any amendment thereto (except

22

for the financial statements, notes to financial statements, financial tables and other tabular, financial and statistical data included therein or omitted therefrom and the Underwriter’s Information as to which such counsel need express no view), at the time the Registration Statement or any such amendment became effective, contained 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 not misleading, (B) that the Prospectus or any amendment or supplement thereto (except for the financial statements, notes to financial statements, financial tables and other tabular, financial and statistical data included therein or omitted therefrom and the Underwriter’s Information, as to which such counsel need express no view), at the time the Registration Statement became effective (or, if the term “Prospectus” refers to the prospectus first filed pursuant to Rule 424(b) of the Act, at the time the Prospectus was issued), at the time any such amended or supplemented Prospectus was issued, at the Closing Date, contained or contains any untrue statement of a material fact or omitted or omits 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, (C) that each Preliminary Prospectus and any Permitted Free Writing Prospectus or any amendment or supplement thereto (except for the financial statements, notes to financial statements, financial tables and other tabular, financial and statistical data included therein or omitted therefrom and the Underwriter’s Information, as to which such counsel need express no view), at the time any such Preliminary Prospectus or Permitted Free Writing Prospectus or amendment or supplement thereto was issued and at the Closing Date, contained or contains any untrue statement of a material fact or omitted or omits 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 or (D) that there is any amendment to the Registration Statement required by the Act or the Rules and Regulations to be filed.

(c) The Underwriter shall, if requested, have received from Silver, Freedman & Taff, L.L.P., counsel for the Underwriter, an opinion dated the Closing Date with respect to such matters as the Underwriter reasonably may request, and such counsel shall have received such papers and information as they request to enable them to pass upon such matters.

(d) The Underwriter shall have received at or prior to the Closing Date from Elias, Matz, Tiernan & Herrick, L.L.P. a memorandum or summary, in form and substance reasonably satisfactory to the Underwriter, with respect to the qualification for offering and sale by the Underwriter of the Shares under the state securities or Blue Sky laws of such jurisdictions as the Underwriter may reasonably have designated to the Company.

(e) Concurrently with the execution of this Agreement, the Underwriter shall receive a letter from BDO Seidman, LLP dated the date hereof and addressed to the Underwriter: (i) confirming that BDO Seidman, LLP is a firm of independent certified public accountants with respect to the Company and the Bank within the meaning of the Act and the Rules and Regulations, the Exchange Act and the Exchange Act Regulations and the Code of Ethics of the American Institute of Certified Public Accountants and no information concerning BDO Seidman, LLP’s relationship with or interests in the Company or the Bank is required to be disclosed in the Prospectus or any Preliminary Prospectus, and stating in effect that in BDO Seidman, LLP’s opinion the consolidated financial statements of the Company included in the Prospectus and each Preliminary Prospectus and covered by BDO Seidman, LLP’s opinion included therein comply as to form in all material respects with the applicable accounting requirements of the Act, the Exchange

23

Act, the Rules and Regulations, the Exchange Act Regulations and accounting principles generally accepted in the United States of America; (ii) stating in effect that, on the basis of certain agreed upon procedures (but not an examination in accordance with generally accepted auditing standards) consisting of a review, in accordance with Statement on Auditing Standards No. 71, of the latest available unaudited interim consolidated financial statements of the Company prepared by the Company, a reading of the minutes of the meetings of the Board of Directors, Executive Committee, Audit Committee and stockholders of the Company and the Bank and consultations with officers of the Company and the Bank responsible for financial and accounting matters, nothing has come to BDO Seidman, LLP’s attention which causes BDO Seidman, LLP to believe that: (A) such unaudited consolidated financial statements including any “Recent Developments” section in the Prospectus or any Preliminary Prospectus do not comply as to form in all material respects with applicable accounting requirements; (B) such unaudited consolidated financial statements including any “Recent Developments” section are not in conformity with accounting principles generally accepted in the United States of America, applied on a basis substantially consistent with that of the audited consolidated financial statements included in the Prospectus and each Preliminary Prospectus; (C) during the period from the date of the latest unaudited consolidated financial statements included in the Prospectus and each Preliminary Prospectus to a specified date not more than five business days prior to the date hereof, there was any material increase in borrowings (defined as securities sold under agreements to repurchase and any other form of debt other than deposits) or non-performing loans, special mention loans or decrease in the deposits or loan allowance, total assets, stockholders’ equity or there was any change in Common Stock outstanding (other than for stock option plans) or (D) there was any material decrease in retained earnings of the Company at the date of such letter as compared with amounts shown in the latest unaudited consolidated balance sheet included in the Prospectus and each Preliminary Prospectus or there was any decrease in net income, net interest income, provision for loan losses or net income after provision or increase in non-interest expense of the Company for the number of full months commencing immediately after the period covered by the latest unaudited consolidated income statement included in the Prospectus and each Preliminary Prospectus and ended on the latest month end prior to the date of the Prospectus and each Preliminary Prospectus as compared to the corresponding period in the preceding year; and (iii) stating that, in addition to the examination referred to in BDO Seidman, LLP’s opinion included in the Prospectus and each Preliminary Prospectus and the performance of the procedures referred to in clause (ii) of this paragraph (e), BDO Seidman, LLP has compared with the general accounting records of the Company’s and/or the Bank’s, as applicable, which are subject to the internal controls of the accounting system and other data prepared by the Company and/or the Bank, as applicable, directly from such accounting records, to the extent specified in such letter, such amounts and/or percentages set forth in the Prospectus and each Preliminary Prospectus as the Underwriter may reasonably request; and they have found such amounts and percentages to be in agreement therewith (subject to rounding).

(f) At the Closing Date, the Underwriter shall have received from BDO Seidman, LLP a letter as of the Closing Date to the effect that they reaffirm the statements made in the letter furnished pursuant to subsection (e) of this Section 6, except that the specified date referred to shall be a date not more than three business days prior to the Closing Date.

24

(g) The Underwriter shall have received on the Closing Date a certificate or certificates of the Company’s Chief Executive Officer and Chief Financial Officer to the effect that, as of the Closing Date, each of them severally represents as follows:

(i) The Registration Statement has become effective under the Act and no stop order suspending the effectiveness of the Registrations Statement has been issued, and no proceedings for such purpose have been taken or are, to her or his knowledge, contemplated by the Commission;

(v) Since the respective dates as of which information is given in the Registration Statement, Prospectus, each Preliminary Prospectus and any Permitted Free Writing Prospectus, there has not been any change in the condition, financial or otherwise, or in the earnings or business affairs of the Company and the Bank considered as one enterprise, having a Material Adverse Effect, whether or not arising in the ordinary course of business.

In such event, the Company and the Underwriter shall not be under any obligation to each other (except to the extent provided in Sections 5 and 8 hereof).

7. CONDITIONS OF THE OBLIGATIONS OF THE COMPANY.

The obligations of the Company to sell and deliver the portion of the Shares required to be delivered as and when specified in this Agreement are subject to the conditions that at the Closing Date, no stop order suspending the effectiveness of the Registration Statement shall have been issued and in effect or proceedings therefor initiated or threatened and the Underwriter shall have transmitted to the Company the payment as set forth in Section 3 hereof.

8. INDEMNIFICATION.

(a) The Company and the Bank agree, jointly and severally:

(i) to indemnify and hold harmless the Underwriter, each of its directors, officers, employees, affiliates, agents, counsel and each person, if any, who controls the Underwriter within the meaning of the Act, against any losses, claims, damages or liabilities to which such Underwriter or any such person or entity may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (1) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, any Permitted Free Writing Prospectus, any “free writing prospectus” (as defined in Rule 405 of the Rules and Regulations) that is not a Permitted Free Writing Prospectus used by the Company in violation of Section 1(j) of this Agreement (an “Impermissible Free Writing Prospectus”), the Prospectus or any amendment or supplement thereto, including the Rule 430A information, if applicable, (2) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances under which they were made, (3) (a) the failure of any person to pay for and accept delivery of the Affiliate Shares that such person has indicated an intention to purchase as of the date of this Agreement or (b) any untrue statement or alleged untrue statement of any material fact contained in any material prepared by or on behalf of or with the consent of the Company for distribution to purchasers of the Affiliate Shares (the “Affiliate Shares Material”) or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances under which they were made or (4) any alleged act or failure to act by the Underwriter in connection with, or relating in any manner to, the Shares or the offering contemplated hereby and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon matters covered by clause (1) or (2) above (provided, however, that the Company shall not be liable under this Section 8(a)(i) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by the Underwriter through its gross negligence or willful misconduct); provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or

26

liability arises out of or is based upon an untrue statement or alleged untrue statement, or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, any Permitted Free Writing Prospectus, any Impermissible Free Writing Prospectus, the Prospectus, the Affiliate Shares Material or such amendment or supplement thereof, in reliance upon and in conformity with the Underwriter’s Information. The foregoing indemnity agreement is in addition to any liability the Company may otherwise have to any such indemnified party.

(ii) to reimburse the Underwriter and each such controlling person upon demand for any legal or other documented out-of-pocket expenses (which expenses shall not include personnel time) reasonably incurred by the Underwriter or such controlling person in connection with investigating or defending any such loss, claim, damage or liability, action or proceeding or in responding to a subpoena or governmental inquiry related to the offering of the Shares, whether or not the Underwriter or controlling person is a party to any action or proceeding. In the event that it is finally judicially determined that the Underwriter were not entitled to receive payments for legal and other expenses pursuant to subparagraphs (i) and (ii), the Underwriter will promptly return all sums that had been advanced pursuant hereto.

(b) The Underwriter will indemnify and hold harmless the Company, each of its directors, officers, employees, agent, counsel and each person, if any, who controls the Company within the meaning of the Act, against any losses, claims, damages or liabilities to which the Company or any such director, officer, employee, agent, counsel, or controlling person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, any Permitted Free Writing Prospectus, any Impermissible Free Writing Prospectus, the Prospectus or any amendment or supplement thereto, or (ii) the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made; and will reimburse any legal or other documented out-of-pocket expenses reasonably incurred by the Company or any such director, officer, employee agent, counsel or controlling person in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding provided, however, that the Underwriter will be liable in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration Statement, any Preliminary Prospectus, any Permitted Free Writing Prospectus, any Impermissible Free Writing Prospectuses, the Prospectus or such amendment or supplement, in reliance upon and in conformity with the Underwriter’s Information. The foregoing indemnity agreement is in addition to any liability the Underwriter may otherwise have to any such indemnified party.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing. No indemnification provided for in Section 8(a) or (b) shall be available to any party who shall fail to give notice as provided in this Subsection if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure

27

to give such notice, but the failure to give such notice shall not relieve the indemnifying party or parties from any liability which it or they may have to the indemnified party for contribution or otherwise than on account of the provisions of Section 8(a) or (b). In case any such proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party and shall pay as incurred the reasonable and documented fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel at its own expense. Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or within 30 days of presentation) the reasonable and documented fees and expenses of the counsel retained by the indemnified party in the event (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) 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 as determined by an opinion of counsel to the indemnified party, or (iii) the indemnifying party shall have failed to assume the defense and employ counsel acceptable to the indemnified party within a reasonable period of time after notice of commencement of the action. Each indemnified party shall use reasonable efforts to cooperate with the indemnifying party in the defense of any such action or claim.

It is understood 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 firm for all such indemnified parties. Such firm shall be designated in writing by the Underwriter in the case of parties indemnified pursuant to Section 8(a) and by the Company in the case of parties indemnified pursuant to Section 8(b). 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 consistent with Sections 8(a) and 8(b) hereof. In addition, the indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any indemnified party is an actual or potential party to such claim, action or proceeding) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding.

(d) If the indemnification provided for in this Section is unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or (b) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law then each indemnifying party shall contribute to such amount paid or payable by

28

such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriter on the other hand in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities, (or actions or proceedings in respect thereof), as well as any other relevant equitable considerations. In any case when the Company is the contributing party and the Underwriter is the indemnified party, the relative benefits received by the Company on the one hand and the Underwriter on the other shall be deemed to be in the same proportion as the total net proceeds from the Offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriter, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriter on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriter agree that it would not be just and equitable if contributions pursuant to this Section 8(d) 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 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Section 8(d) shall be deemed to include any documented legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any the such action or claim. Notwithstanding the provisions of this Section 8(d), (i) the Underwriter shall not be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Shares sold through the Underwriter, and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 8(d), each person who controls the Underwriter within the meaning of the Act shall have the same rights to contribution as the Underwriter, and each person who controls the Company within the meaning of the Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company subject in each case to the preceding sentence. The obligations of the Company under this Section 8(d) shall be in addition to any liability which the Company may otherwise have and the obligations of the Underwriter under this Section 8(d) shall be in addition to any liability that the Underwriter may otherwise have.

(e) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section and the representations and warranties of the Company and the Underwriter 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 Underwriter or any person controlling the Underwriter or the Company, its directors or officers or any persons controlling the Company, (ii) acceptance of any Shares and payment therefor hereunder, and (iii) any termination of this Agreement. A successor of the Underwriter, or to the Company, its directors or officers, or any person controlling the

29

Company, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section.
