| **Item 1.01** | **<u>Entry into a Material Definitive Agreement</u>** |

---

On January 31, 2026, Columbia Financial, Inc., a Delaware corporation (the "<u>Company</u>"), entered into an Agreement and Plan of Merger (the "<u>Merger Agreement</u>") with Columbia Financial, Inc., a newly-formed Maryland corporation (the "<u>Holding Company</u>"), Columbia Bank MHC, the parent mutual holding company of the Company (the "<u>MHC</u>"), and Northfield Bancorp, Inc., a Delaware corporation ("<u>Northfield</u>"). The Merger Agreement was unanimously approved by the Board of Directors of each of the parties.

Concurrently with the adoption of the Merger Agreement, the Boards of Directors of the Company, the Holding Company, the MHC and Columbia Bank, the Company's wholly-owned banking subsidiary, adopted a Plan of Conversion and Reorganization (the "<u>Plan</u>"), pursuant to which Columbia Bank will convert from the mutual holding company form of organization to the fully-public stock holding company form of organization (the "<u>Conversion</u>").

***Plan of Conversion and Reorganization***

The Plan provides for the sale of shares of common stock of the Holding Company, par value $0.01 per share (the "<u>Holding Company Common Stock</u>"), to depositors (and certain eligible borrowers) of Columbia Bank and other members of the public, and for the exchange of shares of the Company, par value $0.01 per share (the "<u>Company Common Stock</u>"), held by persons other than the MHC for shares of Holding Company Common Stock, based on the appraised pro forma market value of the Holding Company, after giving effect to the merger with Northfield, as determined by an independent appraiser (such appraisal, the "<u>Independent Valuation</u>"). Upon the completion of the Conversion, the Holding Company will succeed to the rights and obligations of the MHC and the Company, both of which will be merged out of existence in connection with the Conversion, and become the parent holding company for Columbia Bank.

The Plan establishes December 31, 2024 as the eligibility record date for determining the eligible account holders of Columbia Bank entitled to receive first priority non-transferable subscription rights to subscribe for shares of Holding Company Common Stock in a subscription offering to be undertaken in connection with the Conversion. The Plan is subject to regulatory approval as well as approval by the members of the MHC (i.e., the depositors of Columbia Bank) and by the stockholders of the Company (including approval by the holders of a majority of the outstanding shares of the Company common stock owned by persons other than the MHC). The MHC currently owns approximately 73.1% of the outstanding shares of Company Common Stock.

The foregoing summary of the Plan is not complete and is qualified in its entirety by reference to the complete text of the Plan, which is filed as Exhibit 2.1 to this Form 8-K and incorporated herein by reference.

***Agreement and Plan of Merger***

Pursuant to the terms of the Merger Agreement and subject to the conditions set forth therein, immediately following the completion of the Conversion, Northfield will merge with and into the Holding Company (the "<u>Merger</u>"), with the Holding Company continuing as the surviving corporation (the "<u>Surviving Entity</u>"). Immediately following the completion of the Merger, the Holding Company will cause Northfield's wholly-owned banking subsidiary, Northfield Bank, to merge with and into Columbia Bank, with Columbia Bank continuing as the surviving institution (the "<u>Bank Merger</u>").

Upon the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger (the "<u>Effective Time</u>"), each share of Northfield's common stock, par value $0.01 per share (the "<u>Northfield Common Stock</u>"), issued and outstanding immediately prior to the Effective Time, other than certain shares held by the Company, the Holding Company, the MHC or Northfield, will be converted, at the election of the holder, into the right to receive either shares of Holding Company Common Stock (the "<u>Stock Consideration</u>") or cash (the "<u>Cash Consideration,</u>" and together with the Stock Consideration, the "<u>Merger Consideration</u>"), as follows: (i) if the final Independent Valuation, immediately prior to the completion of the Conversion (the "<u>Final Independent Appraisal</u>") is less than $2.3 billion, 1.425 shares of Holding Company Common Stock (the "<u>Merger Exchange Ratio</u>") or $14.25 in cash (the "<u>Per Share Cash Consideration</u>"); (ii) if the Final Independent Valuation is equal to or greater than $2.3 billion and less than $2.6 billion, the Merger Exchange Ratio will be increased to 1.450 shares of Holding Company Common Stock and the Per Share Cash Consideration will be increased to $14.50; or (iii) if the Final Independent Valuation is greater than $2.6 billion, the Merger Exchange Ratio will be increased to 1.465 shares of Holding Company Common Stock and the Per Share Cash Consideration will be increased to $14.65. No more than 30% of the shares of Northfield Common Stock issued and outstanding as of the Effective Time (excluding shares of Northfield Common Stock to be canceled as provided the Merger Agreement) will be converted into the aggregate Cash Consideration.

Additionally, the parties agreed that, if the valuation range of the Conversion at the midpoint of such range decreases by 20% or more from the midpoint of the preliminary valuation range (the "Preliminary Midpoint") provided by the Company's independent appraiser at the time of first public announcement of the Merger, (i) the Company may, in its sole discretion after consultation with its financial advisor, delay the Conversion; provided, however, such delayed Conversion must close no later than January 31, 2027; or (ii) the Company will engage in good faith negotiations to adjust the amount of the Merger Consideration taking into account such decrease from the Preliminary Midpoint.

*Treatment of Northfield Equity Awards*

Upon the terms and subject to the conditions set forth in the Merger Agreement, at the Effective Time, each outstanding equity award with respect to Northfield Common Stock will be treated as follows:

*Restricted Stock*: Immediately prior to the Effective Time, each share of Northfield Common Stock subject to time-based vesting that is outstanding immediately prior to the Effective Time will fully vest and be treated as an issued and outstanding share of Northfield Common Stock for purposes of the Merger Agreement.

*Performance-Based Restricted Stock Units*: Immediately prior to the Effective Time, each performance-vesting restricted stock unit award of Northfield will accelerate in full and fully vest, with any applicable performance-based vesting condition to be deemed achieved at the greater of the target level of performance or actual annualized performance measured as of the most recent completed fiscal quarter and be treated as an issued and outstanding share of Northfield Common Stock for purposes of the Merger Agreement.

*Stock Options*: Each option to purchase Northfield Common Stock (each, a "<u>Northfield Option</u>") that is outstanding immediately prior to the Effective Time, will be cancelled and converted automatically into an option to purchase shares of Holding Company common stock and will continue to be subject to the same terms and conditions as applied to the Northfield Option immediately prior to the Effective Time. The number of shares of Holding Company Common Stock subject to each assumed Northfield Option will be equal to the number of shares of Northfield Common Stock subject to such Northfield Option immediately prior to the Effective Time, multiplied by the Merger Exchange Ratio, rounded down to the nearest whole share. The per share exercise price of each assumed Northfield Option will also be adjusted by dividing the per share exercise price of such Northfield Option by the Merger Exchange Ratio, rounded up to the nearest cent.

*Representations and Warranties; Covenants*

The Merger Agreement contains customary representations and warranties from both the Company and Northfield, and each party has agreed to customary covenants, including, among others, relating to (1) the conduct of each party's business during the interim period between the execution of the Merger Agreement and the Effective Time, (2) the obligation of each party to call a meeting of its stockholders to approve the Merger Agreement, and (3) Northfield's non-solicitation obligations related to alternative business combination proposals.

Under the Merger Agreement, each of the Company and Northfield has agreed to use its reasonable best efforts to obtain as promptly as practicable all consents required to be obtained from any governmental authority or other third party that are necessary or advisable to consummate the transactions contemplated by the Merger Agreement (including the Merger and the Bank Merger). Notwithstanding such general obligation to obtain such consents of governmental authorities, neither the Company nor Northfield is required to take any action that would reasonably be expected to have a material adverse effect on the Surviving Entity and its subsidiaries, taken as a whole, after giving effect to the Merger (measured on a scale relative only to the size of Northfield and its subsidiaries, taken as a whole, without the Company and its subsidiaries) (a "<u>Materially Burdensome Regulatory Condition</u>").

*Governance*

Pursuant to the Merger Agreement, as of the Effective Time, the Board of Directors of the Holding Company will be comprised of nine Columbia directors and four members of the Board of Directors of Northfield, to be selected by the Company, one of whom will be Steven M. Klein, the Chairman, President and Chief Executive Officer of Northfield (the "<u>Northfield Directors</u>"), provided that the Northfield Directors must meet any applicable requirements or standards that may be imposed by a regulatory agency for service on the Board of Directors of the Holding Company and otherwise be reasonably acceptable to the Nominating/Corporate Governance Committee of the Board of Directors of the Company. In addition, effective as of the effective time of the Bank Merger, each of the Northfield Directors will also be appointed to the Board of Directors of Columbia Bank. Each Northfield Director will serve on each such Board of Directors for at least four years from the Effective Time.

At the Effective Time, Steven M. Klein will also be appointed as Senior Executive Vice President and Chief Operating Officer of the Holding Company and Columbia Bank.

*Closing Conditions*

The completion of the Merger is subject to customary conditions, including (1) approval of the Merger Agreement by the Company's and Northfield's stockholders, (2) authorization for listing on NASDAQ of the shares of Holding Company Common Stock to be issued in the Merger, subject to official notice of issuance, (3) effectiveness of the Registration Statement on Form S-4 for Holding Company Common Stock to be issued in the Merger, (4) the receipt of specified governmental consents and approvals required for the Merger and the Bank Merger, including from the Board of Governors of the Federal Reserve System and the Office of the Comptroller of the Currency, and termination or expiration of all applicable waiting periods in respect thereof, in each case without the imposition of a Materially Burdensome Regulatory Condition, (5) the absence of any order, injunction, decree or other legal restraint preventing the completion of the Merger or the Bank Merger or making the completion of the Merger or the Bank Merger illegal and (6) the consummation of the Conversion. Each party's obligation to complete the Merger is also subject to certain additional customary conditions, including (i) subject to certain exceptions, the accuracy of the representations and warranties of the other party, (ii) performance in all material respects by the other party of its obligations under the Merger Agreement and (iii) receipt by such party of an opinion from counsel to the effect that the Merger, will qualify as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended.

*Termination; Termination Fee*

The Merger Agreement provides certain termination rights for both the Company and Northfield and further provides that a termination fee of $23,700,000 will be payable by either Northfield or the Company, as applicable, following termination of the Merger Agreement under certain circumstances involving a third party. The Merger Agreement also provides for the payment of a termination fee of $6,000,000 by the Company following the termination of the Merger Agreement under certain circumstances.

*Important Statement Regarding Merger Agreement*

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, which is attached hereto as Exhibit 2.2 and is incorporated herein by reference.

The representations, warranties and covenants of each party set forth in the Merger Agreement have been made only for the purposes of, and were and are solely for the benefit of the parties to, the Merger Agreement, may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the parties that differ from those applicable to investors. Accordingly, the representations and warranties may not describe the actual state of affairs at the date they were made or at any other time, and investors should not rely on them as statements of fact. In addition, such representations and warranties (1) will not survive consummation of the Merger, and (2) were made only as of the date of the Merger Agreement or such other date as is specified in the Merger Agreement. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the parties' public disclosures. Accordingly, the Merger Agreement is included with this filing only to provide investors with information regarding the terms of the Merger Agreement, and not to provide investors with any factual information regarding the Company or Northfield, their respective affiliates or their respective businesses. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding the Company, Northfield, their respective affiliates or their respective businesses, the Merger Agreement and the Merger that will be contained in, or incorporated by reference into, the registration statement on Form S-4 that will include a joint proxy statement of the Company and Northfield and also constitute a prospectus of the Holding Company, as well as in the annual reports on Form 10-K, quarterly reports on Form 10-Q and other filings that each of the Company and Northfield make with the Securities and Exchange Commission (the "<u>SEC</u>").

***Support Agreements***

Concurrently with the execution and delivery of the Merger Agreement, each of the directors of Northfield (the "<u>Support Agreement Holders</u>") has entered into a support agreement with the Company (the "<u>Northfield Support Agreement</u>") pursuant to which, among other things, each Support Agreement Holder has agreed, subject to the terms of the Northfield Support Agreement, to (i) vote the shares of Northfield Common Stock over which he or she has the sole power to vote or direct the voting thereof (collectively, the "<u>Subject Northfield Shares</u>"), in favor of the approval of the Merger Agreement and (ii) not transfer the Subject Northfield Shares, with certain limited exceptions. The Northfield Support Agreement will terminate upon the earlier of the termination of the Merger Agreement or the Effective Time.

Each of the directors of the Company also entered into a similar support agreement with Northfield (the "<u>Company Support Agreement</u>") pursuant to which, among other things, each director of the Company has agreed to (i) vote the shares of Company Common Stock over which he or she has the sole power to vote or direct the voting thereof (the "<u>Subject Company Shares</u>") in favor of the approval of the Merger Agreement and the Plan of Conversion and (ii) not transfer the Subject Company Shares, with certain limited exceptions. The Company Support Agreement will terminate upon the earlier of the termination of the Merger Agreement or the Effective Time.

The foregoing descriptions of the Northfield Support Agreement and the Company Support Agreement do not purport to be complete and are qualified in their entirety by reference to the full texts of the Northfield Support Agreements and the Company Support Agreements, forms of which are attached hereto as Exhibits 10.1 and 10.2, respectively, and incorporated herein by reference.

**Disclaimer and Caution About Forward-Looking Statements**

Certain statements in this communication constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995, as amended, which statements involve inherent risks and uncertainties. Examples of forward-looking statements include, but are not limited to, statements regarding the outlook and expectations of Columbia and Northfield, respectively, with respect to the proposed transaction, the strategic benefits and financial benefits of the proposed transaction, including the expected impact of the proposed transaction on the combined company's future financial performance (including anticipated accretion to earnings per share, the tangible book value earn-back period and other operating and return metrics), the timing of the closing of the proposed transaction, and the ability to successfully integrate the combined businesses. Such statements are often characterized by the use of qualified words (and their derivatives) such as "may," "will," "anticipate," "could," "should," "would," "believe," "contemplate," "expect," "estimate," "continue," "plan," "project" and "intend," as well as words of similar meaning or other statements concerning opinions or judgment of Columbia or Northfield or their respective management about future events. Forward-looking statements are based on assumptions as of the time they are made and are subject to risks, uncertainties and other factors that are difficult to predict with regard to timing, extent, likelihood and degree of occurrence, which could cause actual results to differ materially from anticipated results expressed or implied by such forward-looking statements. Such risks, uncertainties and assumptions, include, among others, the following: (i) the occurrence of any event, change or other circumstances that could give rise to the right of one or both of the parties to terminate the merger agreement; (ii) the failure to obtain necessary regulatory approvals (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the proposed transaction) and the possibility that the proposed transaction does not close when expected or at all because required regulatory approvals, the approval by Columbia's and/or Northfield's stockholders, or other approvals and the other conditions to closing are not received or satisfied on a timely basis or at all; (iii) the outcome of any legal proceedings that may be instituted against Columbia or Northfield; (iv) the possibility that the anticipated benefits of the proposed transaction, including anticipated cost savings and strategic gains, are not realized when expected or at all, including as a result of changes in, or problems arising from, general economic and market conditions, interest and exchange rates, monetary policy, laws and regulations and their enforcement, and the degree of competition in the geographic and business areas in which Columbia and Northfield operate; (v) the possibility that the integration of the two companies may be more difficult, time-consuming or costly than expected; (vi) the possibility that the final appraisal of Columbia conducted by RP Financial, LC will differ from the preliminary appraisal conducted by RP Financial, LC; (vii) Columbia's ability to successfully complete the Conversion; (viii) the impact of purchase accounting with respect to the proposed transaction, or any change in the assumptions used regarding the assets acquired and liabilities assumed to determine their fair value and credit marks; (ix) the possibility that the proposed transaction may be more expensive or take longer to complete than anticipated, including as a result of unexpected factors or events; (x) the diversion of management's attention from ongoing business operations and opportunities; (xi) potential adverse reactions of Columbia's or Northfield's customers or changes to business or employee relationships, including those resulting from the announcement or completion of the proposed transaction; (xii) a material adverse change in the financial condition of Columbia or Northfield; (xiii) changes in Columbia's or Northfield's share price before closing; (xiv) risks relating to the potential dilutive effect of shares of Columbia's common stock to be issued in the proposed transaction; (xv) general competitive, economic, political and market conditions, including the impact of any potential government shutdown; (xvi) major catastrophes such as earthquakes, floods or other natural or human disasters, including infectious disease outbreaks; and (xvii) other factors that may affect future results of Columbia or Northfield, including, among others, changes in asset quality and credit risk; the imposition of tariffs and any retaliatory responses; the inability to sustain revenue and earnings growth; changes in interest rates; deposit flows; inflation; customer borrowing, repayment, investment and deposit practices; the impact, extent and timing of technological changes; capital management activities; and other actions of the Federal Reserve Board and legislative and regulatory actions and reforms.

These factors are not necessarily all of the factors that could cause Columbia's, Northfield's or the combined company's actual results, performance or achievements to differ materially from those expressed in or implied by any of the forward-looking statements. Other factors, including unknown or unpredictable factors, also could harm Columbia's, Northfield's or the combined company's results.

Although each of Columbia and Northfield believes that its expectations with respect to forward-looking statements are based upon reasonable assumptions based on its existing knowledge of its business and operations, there can be no assurance that actual results of Columbia or Northfield will not differ materially from any projected future results expressed or implied by such forward-looking statements. Additional factors that could cause results to differ materially from those described above can be found in Columbia's most recent annual report on Form 10-K for the fiscal year ended December 31, 2024, quarterly reports on Form 10-Q, and other documents subsequently filed by Columbia with the SEC, and in Northfield's most recent annual report on Form 10-K for the fiscal year ended December 31, 2024, and its other filings with the SEC and quarterly reports on Form 10-Q, and other documents subsequently filed by Northfield with the SEC. The actual results anticipated may not be realized or, even if substantially realized, they may not have the expected consequences to or effects on Columbia, Northfield or each of their respective businesses or operations. Investors are cautioned not to rely too heavily on any such forward-looking statements. Columbia and Northfield urge you to consider all of these risks, uncertainties and other factors carefully in evaluating all such forward-looking statements made by Columbia and Northfield. Forward-looking statements speak only as of the date they are made and Columbia and/or Northfield undertake no obligation to update or clarify these forward-looking statements, whether as a result of new information, future events or otherwise, except to the extent required by applicable law.

(i) **PLAN OF CONVERSION AND REORGANIZATION**

**OF**

**COLUMBIA BANK MHC**

**1.** **INTRODUCTION** 

This Plan of Conversion and Reorganization (the "Plan") provides for the conversion and reorganization of Columbia Bank MHC, a federally-chartered mutual holding company (the "Mutual Holding Company"), from the mutual to the capital stock form of organization (the "Conversion"). Currently, the Mutual Holding Company owns approximately 73.1% of the outstanding shares of common stock of Columbia Financial, Inc., a Delaware corporation (the "Mid-Tier Holding Company"), and the Mid-Tier Holding Company owns 100% of the outstanding shares of common stock of Columbia Bank (the "Bank"), a federally-chartered savings association that has elected and received regulatory approval to operate as a "covered savings association" pursuant to Section 5A of the Home Owners' Loan Act, as amended, and the regulations of the Office of the Comptroller of the Currency promulgated thereunder.

As part of the Conversion, (i) a new stock holding company (the "Holding Company") will be established to succeed to all of the rights and obligations of the Mutual Holding Company and the Mid-Tier Holding Company, and (ii) the Holding Company will issue shares of Holding Company Common Stock in the Offering, the Exchange Offering and the Merger. The Subscription Shares will be offered for sale in the Offering upon the terms and conditions set forth in this Plan. The subscription rights granted to Participants in the Subscription Offering are set forth in Sections 8 through 11 of this Plan. All sales of Subscription Shares in the Community Offering or in the Firm Commitment Underwritten Offering, or in any other manner permitted by the Bank Regulators, will be at the sole discretion of the Boards of Directors of the Bank and the Holding Company. As part of the Conversion, each Minority Stockholder will receive Exchange Shares in exchange for its Minority Shares in the Exchange Offering. The Conversion will have no impact on depositors, borrowers or other customers of the Bank. After the Conversion, the Bank's insured deposits will continue to be insured by the FDIC to the extent provided by applicable law.

The purpose of the Conversion is to convert the Mutual Holding Company to the capital stock form of organization, which will, among other things, permit the Holding Company to acquire the Acquiree Corporation and provide the Bank and the Holding Company with additional capital to grow and respond to changing regulatory and market conditions. The Conversion will also provide the Bank and the Holding Company with greater flexibility to undertake future corporate transactions, including mergers and acquisitions and branch expansions.

This Plan has been unanimously adopted by the Boards of Directors of the Mutual Holding Company, the Mid-Tier Holding Company and the Bank. This Plan also must each be approved by at least: (i) a majority of the total votes eligible to be cast by Voting Members at the Members Meeting; (ii) two-thirds of the total votes eligible to be cast by Stockholders at the Stockholders Meeting; and (iii) a majority of the total votes eligible to be cast by Minority Stockholders at the Stockholders Meeting. Approval of this Plan by the Voting Members and by the Stockholders shall constitute approval of each of the constituent transactions necessary to implement this Plan, including the MHC Merger and the Mid-Tier Merger. The Federal Reserve must approve this Plan before it is presented to Voting Members and Stockholders for their approval.

After adoption of this Plan by the Boards of Directors of the Bank, the Mid-Tier Holding Company and the Mutual Holding Company, this Plan, together with all other requisite material, shall be submitted to the Bank Regulators for approval. Notice of the adoption of this Plan by the Boards of Directors of the Bank, the Mutual Holding Company and the Mid-Tier Holding Company will be published in a newspaper having general circulation in each community in which an office of the Bank is located, and copies of this Plan will be made available at each office of the Bank for inspection by Members. The Mutual Holding Company will publish a notice of the filing with the Bank Regulators of an application to convert in accordance with the provisions of this Plan as well as notices required in connection with any holding company application, merger application or other application required to complete the Conversion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. Promptly following approval by the Bank Regulators, this Plan will be submitted to: (i) a vote of the Voting Members at the Members Meeting and (ii) a vote of the Stockholders at the Stockholders Meeting. The Mutual Holding Company will mail to all Voting Members, at their last known address appearing on the records of the Bank as of the Member Voting Record Date, a proxy statement in either long or summary form describing this Plan, which will be submitted to a vote of Voting Members at the Members Meeting. The Mid-Tier Holding Company will mail to all Stockholders as of the Stockholder Voting Record Date a proxy statement describing this Plan, which will be submitted to a vote of Stockholders at the Stockholders Meeting. The Holding Company also will mail to all Participants a Prospectus and Order Form for the purchase of Subscription Shares. In addition, all Participants will receive, or will be given the opportunity to request by either telephone or by letter addressed to the Bank's Secretary, a copy of this Plan as well as the articles of incorporation and bylaws of the Holding Company. This Plan must be approved by at least: (i) a majority of the total votes eligible to be cast by Voting Members at the Members Meeting; (ii) two-thirds of the total votes eligible to be cast by Stockholders at the Stockholders Meeting; and (iii) a majority of the total votes eligible to be cast by Minority Stockholders at the Stockholders Meeting. Upon such approval of this Plan, the Mutual Holding Company, the Mid-Tier Holding Company, the Holding Company and the Bank will take all other necessary steps pursuant to applicable laws and regulations to consummate the Conversion. The Conversion must be completed within twenty-four (24) months of the approval of this Plan by Voting Members.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. The period for the Subscription Offering will be not less than twenty (20) days nor more than forty-five (45) days from the date Participants are first mailed a Prospectus and Order Form, unless extended. Any Subscription Shares for which subscriptions have not been received in the Subscription Offering may be issued in a Community Offering or a Firm Commitment Underwritten Offering, or in any other manner permitted by the Bank Regulators. All sales of Subscription Shares must be completed within forty-five (45) days after the last day of the Subscription Offering unless the offering period is extended by the Mutual Holding Company and the Holding Company with the approval of the Bank Regulators.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. The Conversion will be effected as follows, or in any other manner that is consistent with the purposes of this Plan and applicable laws and regulations. The choice of which method to effect the Conversion will be made by the Boards of Directors of the Mutual Holding Company, the Mid-Tier Holding Company and the Bank immediately before the closing of the Conversion. Each of the steps set forth below shall be deemed to occur in such order as is necessary to consummate the Conversion pursuant to this Plan, the intent of the Boards of Directors of the Mutual Holding Company, the Mid-Tier Holding Company and the Bank, and applicable federal and state regulations and policy. Approval of this Plan by Voting Members and Stockholders also shall constitute approval of each of the transactions necessary to implement this Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) The Holding Company will be organized
 as a first-tier stock subsidiary of the Mid-Tier Holding Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) The Mutual Holding Company will merge
 with the Mid-Tier Holding Company, with the Mid-Tier Holding Company as the surviving entity,
 pursuant to the Agreement of Merger attached hereto as <u>Exhibit A</u>, whereby the
 shares of Mid-Tier Holding Company common stock held by the Mutual Holding Company will be
 canceled and Members will constructively receive liquidation interests in the Mid-Tier Holding
 Company in exchange for their ownership interests in the Mutual Holding Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) Immediately after the MHC Merger, the
 Mid-Tier Holding Company will merge with the Holding Company, with the Holding Company as
 the surviving entity, pursuant to the Agreement of Merger attached hereto as <u>Exhibit B</u>,
 whereby the Bank will become the wholly-owned subsidiary of the Holding Company. As part
 of the Mid-Tier Merger, the liquidation interests in the Mid-Tier Holding Company constructively
 received by Members as part of the MHC Merger will automatically, without further action
 on the part of the holders thereof, be exchanged for interests in the Liquidation Account,
 and each Minority Share shall automatically, without further action on the part of the holder
 thereof, be converted into and become the right to receive an Exchange Share based upon the
 Exchange Ratio.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) Immediately after the Mid-Tier Merger,
 the Holding Company will offer for sale the Subscription Shares in the Offering.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) The Holding Company will contribute at
 least 50% of the net proceeds of the Offering to the Bank in constructive exchange for additional
 shares of common stock of the Bank and in exchange for the Bank Liquidation Account.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. As part of the Conversion, the Minority Shares outstanding immediately before the consummation of the Conversion shall automatically, without further action on the part of the holders thereof, be converted into and become the right to receive Exchange Shares based upon the Exchange Ratio. The basis for exchange of Minority Shares for Exchange Shares shall be fair and reasonable. Options to purchase shares of Mid-Tier Holding Company common stock that are outstanding immediately before the consummation of the Conversion shall be converted into options to purchase shares of Holding Company Common Stock, with the number of shares subject to the option and the exercise price per share to be adjusted based upon the Exchange Ratio so that the aggregate exercise price remains unchanged, and with the duration of the option remaining unchanged.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. The Holding Company shall register the Conversion Stock with the SEC and any appropriate state securities authorities. In addition, the Mid-Tier Holding Company shall prepare preliminary proxy materials as well as other applications and information for review by the SEC in connection with the solicitation of Stockholder approval of this Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;G. All assets, rights, interests, privileges, powers, franchises and property (real, personal and mixed) of the Mid-Tier Holding Company and the Mutual Holding Company shall be automatically transferred to and vested in the Holding Company by virtue of the Conversion without any deed or other document of transfer. The Holding Company, without any order or action on the part of any court or otherwise and without any documents of assumption or assignment, shall hold and enjoy all of the properties, franchises and interests, including appointments, powers, designations, nominations and all other rights and interests as the agent or other fiduciary in the same manner and to the same extent as such rights, franchises, and interests and powers were held or enjoyed by the Mid-Tier Holding Company and the Mutual Holding Company. The Holding Company shall be responsible for all of the liabilities, restrictions and duties of every kind and description of the Mid-Tier Holding Company and the Mutual Holding Company immediately before the consummation of the Conversion, including liabilities for all debts, obligations and contracts of the Mid-Tier Holding Company and the Mutual Holding Company, matured or unmatured, whether accrued, absolute, contingent or otherwise and whether or not reflected or reserved against on balance sheets, books of accounts or records of the Mid-Tier Holding Company and the Mutual Holding Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;H. The home office and branch offices of the Bank shall be unaffected by the Conversion. The executive offices of the Holding Company shall be located at the current executive offices of the Mutual Holding Company and Mid-Tier Holding Company.

**4.** **HOLDING COMPANY APPLICATIONS AND APPROVALS** 

The Boards of Directors of the Mutual Holding Company, the Mid-Tier Holding Company, the Holding Company and the Bank shall take all necessary steps to convert the Mutual Holding Company to stock form, form the Holding Company and complete the Offering. The Mutual Holding Company, Mid-Tier Holding Company, Bank and Holding Company shall make timely applications to the Bank Regulators and filings with the SEC for any requisite regulatory approvals to complete the Conversion.

**5.** **SALE OF SUBSCRIPTION SHARES** 

The Subscription Shares will be offered for sale in the Subscription Offering to the Participants in the respective priorities set forth in this Plan. The Subscription Offering may begin as early as the mailing of the proxy statement for the Members Meeting. The Holding Company Common Stock will not be insured by the FDIC. The Bank will not extend credit to any Person to purchase shares of Holding Company Common Stock.

Any Subscription Shares for which subscriptions have not been received in the Subscription Offering may be issued in the Community Offering, subject to the terms and conditions of this Plan. The Community Offering, if any, will involve an offering of unsubscribed Subscription Shares directly to the general public with a first preference given to natural persons and trusts of natural persons residing in the Local Community and a second preference given to Minority Stockholders as of the Stockholder Voting Record Date. The Community Offering may begin concurrently with, or at any time during or after the Subscription Offering. The offer and sale of Subscription Shares before the Members Meeting, however, is subject to the approval of this Plan by the Voting Members and by the Stockholders, including Minority Stockholders.

If feasible, any Subscription Shares remaining unsold after the Subscription Offering and any Community Offering may be offered for sale in a Firm Commitment Underwritten Offering, or in any manner approved by the Bank Regulators that will achieve a widespread distribution of the Subscription Shares. The issuance of Subscription Shares in the Subscription Offering and any Community Offering will be consummated simultaneously on the date the sale of Subscription Shares is consummated in any Firm Commitment Underwritten Offering, and only if the required minimum number of Subscription Shares will be issued.

**6.** **PURCHASE PRICE AND NUMBER OF SUBSCRIPTION SHARES** 

The total number of shares of Conversion Stock to be offered in the Conversion will be determined jointly by the Boards of Directors of the Mutual Holding Company, the Mid-Tier Holding Company and the Holding Company immediately before the commencement of the Subscription Offering, and will be based on the Appraised Value Range and the Subscription Price. The Offering Range will be equal to the Appraised Value Range multiplied by the Majority Ownership Interest (as adjusted to reflect assets held by the Mutual Holding Company (other than shares of stock of the Mid-Tier Holding Company)). The estimated pro forma consolidated market value of the Holding Company will be subject to adjustment within the Appraised Value Range if necessitated by market or financial conditions, with the receipt of any required approvals of the Bank Regulators, and the maximum of the Appraised Value Range may be increased by up to 15% after the commencement of the Subscription Offering to reflect changes in market and financial conditions or demand for the shares. The number of shares of Conversion Stock issued in the Conversion will be equal to the estimated pro forma consolidated market value of the Holding Company, as may be amended, divided by the Subscription Price, and the number of Subscription Shares issued in the Offering will be equal to the product of (i) the estimated pro forma consolidated market value of the Holding Company, as may be amended, divided by the Subscription Price, and (ii) the Majority Ownership Interest (as adjusted to reflect assets held by the Mutual Holding Company (other than shares of stock of the Mid-Tier Holding Company)).

If the product of the Subscription Price multiplied by the number of shares of Conversion Stock to be issued in the Conversion is below the minimum of the Appraised Value Range, or materially above the maximum of the Appraised Value Range, a resolicitation of purchasers may be required, provided that up to a 15% increase above the maximum of the Appraised Value Range will not be deemed material so as to require a resolicitation. Any resolicitation shall be effected in such manner and within such time as the Mutual Holding Company, the Mid-Tier Holding Company and the Holding Company shall establish, if all required regulatory approvals are obtained.

Notwithstanding the foregoing, shares of Conversion Stock will not be issued unless, before the consummation of the Conversion, the Independent Appraiser confirms to the Bank, the Mutual Holding Company, the Holding Company, and the Bank Regulators, that, to the best knowledge of the Independent Appraiser, nothing of a material nature has occurred which, taking into account all relevant factors, would cause the Independent Appraiser to conclude that the number of shares of Conversion Stock issued in the Conversion multiplied by the Subscription Price is incompatible with its estimate of the aggregate consolidated pro forma market value of the Holding Company. If such confirmation is not received, the Holding Company may cancel the Offering and the Exchange Offering, extend the Offering and establish a new Subscription Price and/or Appraised Value Range, hold a new Offering and Exchange Offering after canceling the Offering and the Exchange Offering, or take such other action as the Bank Regulators may permit.

The Holding Company Common Stock to be issued in the Conversion shall be fully paid and nonassessable.

**7.** **RETENTION OF CONVERSION PROCEEDS BY THE HOLDING COMPANY** 

The Holding Company may retain up to 50% of the net proceeds of the Offering. The Holding Company believes that the Offering proceeds will provide economic strength to the Holding Company and the Bank for the future in a highly competitive and regulated financial services environment, and would support the growth in the operations of the Holding Company and the Bank through increased lending, acquisitions of financial service organizations, continued diversification into other related businesses and other business and investment activities, including the possible payment of dividends and possible repurchases of the Holding Company Common Stock as permitted by applicable state law and by applicable federal regulations and policy.

**8.** **SUBSCRIPTION RIGHTS OF ELIGIBLE ACCOUNT HOLDERS (FIRST PRIORITY)** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Each Eligible Account Holder shall have nontransferable subscription rights to subscribe for in the Subscription Offering up to the greater of $3,000,000 of the Subscription Shares issued in the Offering, 0.10% of the total number of Subscription Shares issued in the Offering, or fifteen times the product (rounded down to the next whole number) obtained by multiplying the number of Subscription Shares offered in the Offering by a fraction of which the numerator is the amount of the Eligible Account Holder's Qualifying Deposit and the denominator is the total amount of Qualifying Deposits of all Eligible Account Holders, in each case on the Eligibility Record Date, subject to the purchase limitations specified in Section 14.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. If Eligible Account Holders exercise subscription rights for a number of Subscription Shares in excess of the total number of such shares eligible for subscription, the Subscription Shares shall be allocated among the subscribing Eligible Account Holders so as to permit each subscribing Eligible Account Holder to purchase a number of shares sufficient to make his or her total allocation of Subscription Shares equal to the lesser of 100 shares or the number of shares for which such Eligible Account Holder has subscribed. Any remaining shares will be allocated among the subscribing Eligible Account Holders whose subscriptions remain unsatisfied in the proportion that the amount of the Qualifying Deposit of each Eligible Account Holder whose subscription remains unsatisfied bears to the total amount of the Qualifying Deposits of all Eligible Account Holders whose subscriptions remain unsatisfied. If the amount so allocated exceeds the amount subscribed for by any one or more Eligible Account Holders, the excess shall be reallocated (one or more times as necessary) among those Eligible Account Holders whose subscriptions are still not fully satisfied on the same principle until all available shares have been allocated.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. Subscription rights as Eligible Account Holders received by Directors and Officers and their Associates that are based on deposits made by such persons during the twelve (12) months preceding the Eligibility Record Date shall be subordinated to the subscription rights of all other Eligible Account Holders, except as permitted by the Bank Regulators.

**9.** **SUBSCRIPTION RIGHTS OF EMPLOYEE PLANS (SECOND PRIORITY)** 

The Employee Plans shall have subscription rights to purchase in the aggregate up to 10% of the Subscription Shares issued in the Offering, including any Subscription Shares to be issued as a result of an increase in the maximum of the Offering Range after commencement of the Subscription Offering and before the completion of the Conversion. Consistent with applicable laws and regulations and practices and policies, the Employee Plans may use funds contributed by the Holding Company or the Bank and/or borrowed from an independent financial institution or from the Holding Company to exercise such subscription rights, and the Holding Company and the Bank may make scheduled discretionary contributions thereto, provided that such contributions do not cause the Holding Company or the Bank to fail to meet any applicable regulatory capital requirements. The Employee Plans shall not be deemed to be Associates or Affiliates of or Persons Acting in Concert with any Director or Officer of the Holding Company or the Bank. Alternatively, if permitted by the Bank Regulators, the Employee Plans may purchase all or a portion of such shares in the open market after the completion of the Conversion.

**10.** **SUBSCRIPTION RIGHTS OF SUPPLEMENTAL ELIGIBLE ACCOUNT HOLDERS (THIRD PRIORITY)** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Each Supplemental Eligible Account Holder shall have nontransferable subscription rights to subscribe for in the Subscription Offering up to the greater of $3,000,000 of the Subscription Shares issued in the Offering, 0.10% of the total number of Subscription Shares issued in the Offering, or fifteen times the product (rounded down to the next whole number) obtained by multiplying the number of Subscription Shares offered in the Offering by a fraction of which the numerator is the amount of the Supplemental Eligible Account Holder's Qualifying Deposit and the denominator is the total amount of Qualifying Deposits of all Supplemental Eligible Account Holders, in each case on the Supplemental Eligibility Record Date, subject to the availability of sufficient shares after filling in full all subscription orders of Eligible Account Holders and Employee Plans and subject to the purchase limitations specified in Section 14.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. If Supplemental Eligible Account Holders exercise subscription rights for a number of Subscription Shares in excess of the total number of such shares eligible for subscription following subscriptions by Eligible Account Holders and Employee Plans, Subscription Shares shall be allocated among the subscribing Supplemental Eligible Account Holders so as to permit each subscribing Supplemental Eligible Account Holder, to the extent possible, to purchase a number of shares sufficient to make his or her total allocation of Subscription Shares equal to the lesser of one hundred (100) shares or the number of shares for which such Supplemental Eligible Account Holder has subscribed. Any remaining shares will be allocated among the subscribing Supplemental Eligible Account Holders whose subscriptions remain unsatisfied in the proportion that the amount of the Qualifying Deposit of such Supplemental Eligible Account Holder whose subscription remains unsatisfied bears to the total amount of the Qualifying Deposits of all Supplemental Eligible Account Holders whose subscriptions remain unsatisfied. If the amount so allocated exceeds the amount subscribed for by any one or more Supplemental Eligible Account Holders, the excess shall be reallocated (one or more times as necessary) among those Supplemental Eligible Account Holders whose subscriptions are still not fully satisfied on the same principle until all available shares have been allocated.

**11.** **SUBSCRIPTION RIGHTS OF OTHER MEMBERS (FOURTH PRIORITY)** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. Each Other Member shall have nontransferable subscription rights to subscribe for in the Subscription Offering up to the greater of $3,000,000 of the Subscription Shares issued in the Offering or 0.10% of the total number of shares of Subscription Shares issued in the Offering, subject to the availability of sufficient shares after filling in full all subscription orders of Eligible Account Holders, Employee Plans and Supplemental Eligible Account Holders and subject to the purchase limitations specified in Section 14.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. If Other Members exercise subscription rights for a number of Subscription Shares is in excess of the total number of such shares available for subscription following subscriptions by Eligible Account Holders, Employee Plans and Supplemental Eligible Account Holders, Subscription Shares will be allocated among Other Members so as to permit each such subscribing Other Member, to the extent possible, to purchase a number of shares sufficient to make his or her total allocation of Subscription Shares equal to the lesser of one hundred (100) shares or the number of shares for which each such Other Member has subscribed. Any remaining shares will be allocated among the subscribing Other Members whose subscriptions remain unsatisfied in the proportion that the amount of the subscription of each such Other Member bears to the total amount of the subscriptions of all Other Members whose subscriptions remain unsatisfied.

**12.** **COMMUNITY OFFERING AND MERGER SHARES** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. If subscriptions are not received for all Subscription Shares offered for sale in the Subscription Offering, shares for which subscriptions have not been received may be offered for sale in the Community Offering through a direct community marketing program which may use a broker, dealer, consultant or investment banking firm experienced and expert in the sale of savings institutions securities. Such entities may be compensated on a fixed fee basis or on a commission basis, or a combination thereof. If orders for Subscription Shares in the Community Offering exceed the number of shares available for sale, shares shall be allocated (to the extent shares remain available) first to cover orders of natural persons (including trusts of natural persons) residing in the Local Community, second to cover orders of Minority Stockholders as of the Stockholder Voting Record Date, and thereafter to cover orders of other members of the general public. If orders for Subscription Shares exceed the number of shares available for sale in a category pursuant to the purchase priorities described above, shares will be allocated within the category so that each member of that category will receive the lesser of one hundred (100) shares or the amount ordered, and thereafter remaining shares will be allocated on an equal number of shares basis per order. In connection with the allocation, orders received for Subscription Shares in the Community Offering will first be filled up to a maximum of two percent (2%) of the shares sold in the Offering, and thereafter any remaining shares will be allocated on an equal number of shares basis per order. The Mutual Holding Company and the Holding Company shall use their best efforts consistent with this Plan to distribute Subscription Shares sold in the Community Offering in such a manner as to promote the widest distribution practicable of such shares. The Holding Company reserves the right to reject any or all orders, in whole or in part, that are received in the Community Offering. Any Person may purchase up to $3,000,000 of the Subscription Shares in the Community Offering, subject to the purchase limitations specified in Section 14.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. If subscriptions totaling at least the minimum of the Offering Range are not received in the Subscription Offering, then unsubscribed Subscription Shares may be issued to stockholders of the Acquiree Corporation in exchange for their shares of the Acquiree Corporation or in any other manner that facilitates the completion of the Merger, provided that total Merger Shares, including Merger Shares issued pursuant to this Section 12.B, are less than 50% of the outstanding Holding Company Common Stock immediately after the closing of the Conversion and Merger. Subscription Shares may only be issued as Merger Shares in order to achieve the minimum of the Offering Range.

**13.** **FIRM COMMITMENT UNDERWRITTEN OFFERING** 

If feasible, the Board of Directors may determine to offer Subscription Shares not sold in the Subscription Offering or any Community Offering for sale in a Firm Commitment Underwritten Offering subject to such terms, conditions and procedures as may be determined by the Mutual Holding Company and the Holding Company, subject to the right of the Holding Company to accept or reject in whole or in part any orders in the Firm Commitment Underwritten Offering. In the Firm Commitment Underwritten Offering, any Person may purchase up to $3,000,000 of the Subscription Shares, subject to the purchase limitations specified in Section 14. In addition, unless otherwise approved or permitted by the Federal Reserve, orders received for Subscription Shares in the Firm Commitment Underwritten Offering will first be filled up to a maximum of two percent (2%) of the shares sold in the Offering, and thereafter any remaining shares will be allocated on an equal number of shares basis per order. Provided the Subscription Offering has begun, the Holding Company may begin the Firm Commitment Underwritten Offering at any time. The Holding Company reserves the right to reject any or all orders, in whole or in part, that are received in the Firm Commitment Underwritten Offering.

If, for any reason, a Firm Commitment Underwritten Offering of Subscription Shares not sold in the Subscription Offering or any Community Offering cannot be effected, or if any insignificant residue of Subscription Shares is not sold in the Subscription Offering, Community Offering, or any Firm Commitment Underwritten Offering, the Holding Company will use its best efforts to make other arrangements for the disposition of unsubscribed shares aggregating at least the minimum of the Offering Range. Such other purchase arrangements will be subject to receipt of any required approval of the Bank Regulators.

**14.** **LIMITATIONS ON PURCHASES** 

The following limitations shall apply to all purchases and issuances of shares of Conversion Stock:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. The maximum number of Subscription Shares that may be subscribed for or purchased in all categories in the Offering by any Person or Participant, together with any Associate or group of Persons Acting in Concert, shall not exceed $10,000,000 of the Subscription Shares issued in the Offering, except that the Employee Plans may subscribe for up to 10% of the Subscription Shares issued in the Offering (including shares issued in the event of an increase in the maximum of the Offering Range of 15%).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. The maximum number of shares of Holding Company Common Stock that may be issued to or purchased in all categories of the Offering by Officers and Directors and their Associates in the aggregate shall not exceed 25% of the shares of Conversion Stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. The maximum number of Subscription Shares that may be subscribed for or purchased in all categories of the Offering by any Person or Participant together with purchases by any Associate or group of Persons Acting in Concert, combined with Exchange Shares and Merger Shares received by any such Person or Participant together with any Associate or group of Persons Acting in Concert, shall not exceed 9.9% of the shares of Conversion Stock, except that this ownership limitation shall not apply to the Employee Plans. However, Minority Stockholders will not be required to sell any shares of Holding Company Common Stock or be limited from receiving any Exchange Shares or Merger Shares or be required to divest themselves of any Exchange Shares as a result of this limitation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. A minimum of twenty-five (25) Subscription Shares must be purchased by each Person or Participant purchasing shares in the Offering to the extent those shares are available; provided, however, that if the product of the minimum number of Subscription Shares purchased multiplied the Subscription Price exceeds $500, then such minimum purchase requirement shall be reduced to such number of shares which when multiplied by the price per share shall not exceed $500, as determined by the Board.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. If the number of shares of Holding Company Common Stock otherwise allocable pursuant to Sections 8 through 13, inclusive, to any Person or that Person's Associates would be in excess of the maximum number of shares permitted as set forth above, the number of shares of Holding Company Common Stock allocated to each such person shall be reduced to the lowest limitation applicable to that Person, and then the number of shares allocated to each group consisting of a Person and that Person's Associates shall be reduced so that the aggregate allocation to that Person and his or her Associates complies with the above limits.

Depending upon market or financial conditions, the Boards of Directors of the Holding Company and the Mutual Holding Company, with the receipt of any required approvals of the Bank Regulators and without further approval of Voting Members, may decrease or increase the purchase limitations in this Plan, provided that the maximum purchase limitations may not be increased to a percentage in excess of 5% of the shares issued in the Offering except as provided below. If the Mutual Holding Company and the Holding Company increase the maximum purchase limitations, the Mutual Holding Company and the Holding Company are only required to resolicit Participants who subscribed for the maximum purchase amount in the Subscription Offering and who indicated a desire to be resolicited on the Order Form and may, in the sole discretion of the Mutual Holding Company and the Holding Company, resolicit certain other large purchasers. In the event of such a resolicitation, the Mutual Holding Company and the Holding Company shall have the right, in their sole discretion, to require such persons to supply immediately available funds for the purchase of additional Subscription Shares. Such persons will be prohibited from paying with a personal check, but the Mutual Holding Company and the Holding Company may allow payment by wire transfer. If the maximum purchase limitation is increased to 5% of the shares issued in the Offering, such limitation may be further increased to 9.99%, provided that orders for Subscription Shares exceeding 5% of the Subscription Shares issued in the Offering shall not exceed in the aggregate 10% of the total Subscription Shares issued in the Offering. Requests to purchase additional Subscription Shares, if the purchase limitation is so increased, will be determined by the Board of Directors of the Holding Company in its sole discretion.

For purposes of this Section 14, (i) Directors, Officers and Employees of the Bank, the Mid-Tier Holding Company, the Mutual Holding Company and the Holding Company or any of their subsidiaries shall not be deemed to be Associates or a group affiliated with each other or otherwise Acting in Concert solely as a result of their capacities as such, (ii) shares purchased by Tax-Qualified Employee Stock Benefit Plans shall not be attributable to the individual trustees or beneficiaries of any such plan for purposes of determining compliance with the limitations set forth in paragraphs A. and B. of this Section 14, and (iii) shares purchased by a Tax-Qualified Employee Stock Benefit Plan pursuant to instructions of an individual in an account in such plan in which the individual has the right to direct the investment, including any plan of the Bank qualified under Section 401(k) of the Code shall be aggregated and included in that individual's purchases and not attributed to the Tax-Qualified Employee Stock Benefit Plan.

Each Person purchasing Subscription Shares in the Offering shall be deemed to confirm that such purchase does not conflict with the above purchase limitations contained in this Plan.

**15.** **PAYMENT FOR SUBSCRIPTION SHARES** 

All payments for Subscription Shares subscribed for in the Subscription Offering and Community Offering must be delivered in full to the Bank or Holding Company, together with a properly completed and executed Order Form, on or before the expiration date of the Offering; provided, however, that if the Employee Plans subscribe for shares in the Subscription Offering, such plans will not be required to pay for the shares at the time they subscribe but rather may pay for such shares subscribed for by such plans at the Subscription Price upon consummation of the Conversion. Subscription funds will be held in a segregated account at the Bank.

Except as set forth in Section 14.E., above, payment for Subscription Shares shall be made by personal check, money order or bank draft from the subscriber. Alternatively, subscribers in the Subscription and Community Offerings may pay for the shares for which they have subscribed by cash or by authorizing the Bank on the Order Form to make a withdrawal from the designated types of Deposit Accounts at the Bank in an amount equal to the aggregate Subscription Price of such shares. Such authorized withdrawal shall be without penalty as to premature withdrawal. If the authorized withdrawal is from a certificate of deposit account, and the remaining balance does not meet the applicable minimum balance requirement, the certificate of deposit shall be canceled at the time of withdrawal, without penalty, and the remaining balance will earn interest at the regular statement savings rate. Funds for which a withdrawal is authorized will remain in the subscriber's Deposit Account but may not be used by the subscriber during the Offering. Thereafter, the withdrawal will be given effect only to the extent necessary to satisfy the subscription (to the extent it can be filled) at the Subscription Price per share. Interest will continue to be earned on any amounts authorized for withdrawal until such withdrawal is given effect. Interest on funds received by check, draft or money order or by cash will be paid by the Bank at not less than the regular statement savings rate. Such interest will be paid from the date payment is processed by the Bank until consummation or termination of the Offering. If for any reason the Offering is not consummated, all payments made by subscribers in the Subscription and Community Offerings will be refunded to them, with interest. In case of amounts authorized for withdrawal from Deposit Accounts, refunds will be made by canceling the authorization for withdrawal. The Bank is prohibited by regulation from knowingly making any loans or granting any lines of credit for the purchase of Subscription Shares in the Offering.

**16.** **MANNER OF EXERCISING SUBSCRIPTION RIGHTS THROUGH ORDER FORMS** 

As soon as practicable after the registration statement prepared by the Holding Company has been declared effective by the SEC and the stock offering materials have been approved by the Bank Regulators, Order Forms will be distributed to the Eligible Account Holders, Employee Plans, Supplemental Eligible Account Holders and Other Members at their last known addresses appearing on the records of the Bank for the purpose of subscribing for shares of Holding Company Common Stock in the Subscription Offering and will be made available for use by those Persons to whom a Prospectus is delivered. Each Order Form will be preceded or accompanied by a Prospectus describing the Mutual Holding Company, the Mid-Tier Holding Company, the Holding Company, the Bank, the Holding Company Common Stock and the Offering. Each Order Form will contain, among other things, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. A specified date by which all Order Forms must be received by the Holding Company, or its agent, which date shall be not less than twenty (20) days, nor more than forty-five (45) days, following the date on which the Order Forms are first mailed to Participants by the Mutual Holding Company or the Holding Company, and which date will constitute the termination of the Subscription Offering unless extended;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. The Subscription Price for the Subscription Shares to be sold in the Offering;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. A description of the minimum and maximum number of Subscription Shares which may be subscribed for pursuant to the exercise of subscription rights or otherwise purchased in the Subscription and Community Offerings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. Instructions as to how the recipient of the Order Form is to indicate thereon the number of Subscription Shares for which such Person elects to subscribe and the available alternative methods of payment therefor;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;E. An acknowledgment that the recipient of the Order Form has received a final copy of the Prospectus before the execution of the Order Form;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F. A statement to the effect that all subscription rights are nontransferable, will be void at the end of the Subscription Offering, and can only be exercised by delivering to the Holding Company or its agent within the subscription period such properly completed and executed Order Form, together with payment in the full amount of the aggregate purchase price as specified in the Order Form for the Subscription Shares for which the recipient elects to subscribe in the Subscription Offering (or by authorizing on the Order Form that the Bank withdraw said amount from the subscriber's Deposit Account(s) at the Bank); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;G. A statement to the effect that the executed Order Form, once received by the Mutual Holding Company or the Holding Company, may not be modified or amended by the subscriber without the consent of the Holding Company.

Notwithstanding the above, the Mutual Holding Company and the Holding Company reserve the right in their sole discretion to accept or reject orders received on photocopied or facsimiled order forms.

**17.** **UNDELIVERED, DEFECTIVE OR LATE ORDER FORM; INSUFFICIENT PAYMENT** 

If Order Forms (a) are not delivered or are not timely delivered by the United States Postal Service, (b) are not received by the Holding Company or are received by the Holding Company or its agent after the expiration date specified thereon, (c) are defectively completed or executed, (d) are not accompanied by the full required payment for the Subscription Shares subscribed for (including cases in which deposit accounts from which withdrawals are authorized are insufficient to cover the amount of the required payment), or (e) are not mailed pursuant to a "no mail" order placed in effect by the Account Holder, the subscription rights of the Participant to whom such rights have been granted will lapse as though such Participant failed to return the completed Order Form within the time period specified thereon; provided, however, that the Holding Company may, but will not be required to, waive any immaterial irregularity on any Order Form or require the submission of corrected Order Forms or the remittance of full payment for subscribed shares by such date as the Holding Company may specify. The interpretation by the Holding Company of terms and conditions of this Plan and of the Order Forms will be final, subject to the authority of the Bank Regulators.

**18.** **RESIDENTS OF FOREIGN COUNTRIES AND CERTAIN STATES** 

The Holding Company will make reasonable efforts to comply with the securities laws of all states in the United States in which Persons entitled to subscribe for Subscription Shares pursuant to this Plan reside. However, no such Person will be issued subscription rights or be permitted to purchase Subscription Shares in the Subscription Offering if such Person resides in a foreign country; or in a state of the United States with respect to which any of the following apply: (a) a small number of Persons otherwise eligible to subscribe for shares under this Plan reside in such state; (b) the issuance of subscription rights or the offer or sale of Subscription Shares to such Persons would require the Holding Company under the securities laws of such state, to register as a broker, dealer, salesman or agent or to register or otherwise qualify its securities for sale in such state; or (c) such registration or qualification would be impracticable for reasons of cost or otherwise.

**19.** **ESTABLISHMENT OF LIQUIDATION ACCOUNTS** 

The Holding Company shall establish a Liquidation Account at the time of the Conversion in an amount equal to the product of (i) the Majority Ownership Interest and (ii) the Mid-Tier Holding Company's total stockholders' equity as reflected in the latest statement of financial condition contained in the final Prospectus used in the Conversion, plus the value of the net assets of the Mutual Holding Company as reflected in the latest statement of financial condition of the Mutual Holding Company before the effective date of the Conversion (excluding its ownership of Mid-Tier Holding Company common stock). Following the Conversion, the Liquidation Account will be maintained for the benefit of the Eligible Account Holders and Supplemental Eligible Account Holders who continue to maintain their Deposit Accounts at the Bank. Each Eligible Account Holder and Supplemental Eligible Account Holder shall, with respect to his Deposit Account, hold a related inchoate interest in a portion of the Liquidation Account balance in relation to his Deposit Account balance at the Eligibility Record Date or Supplemental Eligibility Record Date, respectively, or to such balance as it may be subsequently reduced, as hereinafter provided. The Holding Company also shall cause the Bank to establish and maintain the Bank Liquidation Account for the benefit of Eligible Account Holders and Supplemental Eligible Account Holders who continue to maintain their Deposit Accounts at the Bank.

In the unlikely event of a complete liquidation of (i) the Bank or (ii) the Bank and the Holding Company (and only in such event) following all liquidation payments to creditors (including those to Account Holders to the extent of their Deposit Accounts), each Eligible Account Holder and Supplemental Eligible Account Holder shall be entitled to receive a liquidating distribution from the Liquidation Account, in the amount of the then adjusted subaccount balance for such Eligible Account Holder's or Supplemental Eligible Account Holder's Deposit Account, before any liquidation distribution may be made to any holders of the Holding Company's capital stock. A merger, consolidation or similar combination with another depository institution or holding company thereof, in which the Holding Company and/or the Bank is not the surviving entity, shall not be deemed to be a complete liquidation for this purpose. In such transactions, the Liquidation Account shall be assumed by the surviving holding company or institution.

In the unlikely event of a complete liquidation of either (i) the Bank or (ii) the Bank and the Holding Company (and only in such event) following all liquidation payments to creditors of the Bank (including those to Account Holders to the extent of their Deposit Accounts), at a time when the Bank has a positive net worth and the Holding Company does not have sufficient assets (other than the stock of the Bank) at the time of liquidation to fund its obligations under the Liquidation Account, the Bank, with respect to the Bank Liquidation Account shall immediately pay directly to each Eligible Account Holder and Supplemental Eligible Account Holder an amount necessary to fund the Holding Company's remaining obligations under the Liquidation Account before any liquidating distribution may be made to any holders of the Bank's capital stock and without making such amount subject to the Holding Company's creditors. Each Eligible Account Holder and Supplemental Eligible Account Holder shall be entitled to receive a distribution from the Bank Liquidation Account, in the amount of the then adjusted subaccount balance for its Deposit Account then held, before any distribution may be made to any holders of the Holding Company's or Bank's capital stock.

In the event of a complete liquidation of the Holding Company where the Bank is not also completely liquidating, or in the event of a sale or other disposition of the Holding Company apart from the Bank, each Eligible Account Holder and Supplemental Eligible Account Holder shall be treated as surrendering such Person's rights to the Liquidation Account and receiving from the Holding Company an equivalent interest in the Bank Liquidation Account. Each such holder's interest in the Bank Liquidation Account shall be subject to the same rights and terms as if the Bank Liquidation Account were the Liquidation Account (except that the Holding Company shall cease to exist).

The initial subaccount balance for a Deposit Account held by an Eligible Account Holder and Supplemental Eligible Account Holder shall be determined by multiplying the opening balance in the Liquidation Account by a fraction, the numerator of which is the amount of the Qualifying Deposits of such Eligible Account Holder or Supplemental Eligible Account Holder and the denominator of which is the total amount of all Qualifying Deposits of all Eligible Account Holders and Supplemental Eligible Account Holders. For Deposit Accounts in existence at both the Eligibility Record Date and the Supplemental Eligibility Record Date, separate initial subaccount balances shall be determined on the basis of the Qualifying Deposits in such Deposit Account on each such record date. Such initial subaccount balance shall not be increased, but shall be subject to downward adjustment as described below.

If, at the close of business on any fiscal year end closing date, commencing on or after the effective date of the Conversion, the deposit balance in the Deposit Account of an Eligible Account Holder or Supplemental Eligible Account Holder is less than the lesser of (i) the balance in the Deposit Account at the close of business on any other annual closing date after the Eligibility Record Date or Supplemental Eligibility Record Date, or (ii) the amount of the Qualifying Deposit in such Deposit Account as of the Eligibility Record Date or Supplemental Eligibility Record Date, then the subaccount balance for such Deposit Account shall be adjusted downward by reducing such subaccount balance in an amount proportionate to the reduction in such deposit balance. In the event of a downward adjustment, the subaccount balance shall not be subsequently increased, notwithstanding any subsequent increase in the deposit balance of the related Deposit Account. If any such Deposit Account is closed, the related subaccount shall be reduced to zero.

The creation and maintenance of the Liquidation Account and the Bank Liquidation Account shall not operate to restrict the use or application of any capital of the Holding Company or the Bank, except that neither the Holding Company nor the Bank shall declare or pay a cash dividend on, or repurchase any of, its capital stock if the effect thereof would cause its equity to be reduced below: (i) the amount required for the Liquidation Account or the Bank Liquidation Account, as applicable; or (ii) the regulatory capital requirements of the Holding Company (to the extent applicable) or the Bank. Neither the Holding Company nor the Bank shall be required to set aside funds in connection with its obligations hereunder relating to the Liquidation Account and the Bank Liquidation Account, respectively. Eligible Account Holders and Supplemental Eligible Account Holders do not retain any voting rights in either the Holding Company or the Bank based on their interests in the Liquidation Account or the Bank Liquidation Account.

The amount of the Bank Liquidation Account shall equal at all times the amount of the Liquidation Account, and the Bank Liquidation Account shall be reduced by the same amount and upon the same terms as any reduction in the Liquidation Account. In no event will any Eligible Account Holder or Supplemental Eligible Account Holder be entitled to a distribution that exceeds such holder's subaccount balance in the Liquidation Account.

For the three (3)-year period following the completion of the Conversion, the Holding Company will not without prior Federal Reserve approval (i) sell or liquidate the Holding Company, or (ii) cause the Bank to be sold or liquidated. Upon the written request of the Federal Reserve the Holding Company shall, or upon the prior written approval of the Federal Reserve the Holding Company may, at any time after two (2) years from the completion of the Conversion, transfer the Liquidation Account to the Bank, at which time the Liquidation Account shall be assumed by the Bank and the interests of Eligible Account Holders and Supplemental Eligible Account Holders will be solely and exclusively established in the Bank Liquidation Account. In the event such transfer occurs, the Holding Company shall be deemed to have transferred the Liquidation Account to the Bank and such Liquidation Account shall be subsumed into the Bank Liquidation Account and shall not be subject in any manner or amount to the claims of the Holding Company's creditors. Approval of this Plan by the Voting Members and Stockholders shall constitute approval of the transactions described herein.

**20.** **VOTING RIGHTS OF STOCKHOLDERS** 

Following consummation of the Conversion, the holders of the voting capital stock of the Holding Company shall have the exclusive voting rights with respect to the Holding Company.

**21.** **RESTRICTIONS ON RESALE OR SUBSEQUENT DISPOSITION OF SUBSCRIPTION SHARES** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. All Subscription Shares purchased by Directors or Officers of the Mutual Holding Company, the Mid-Tier Holding Company, the Holding Company or the Bank in the Offering shall be subject to the restriction that, except as provided in this Section or as may be approved by the Bank Regulators, no interest in such shares may be sold or otherwise disposed of for value for a period of one (1) year following the date of purchase in the Offering.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. The restriction on disposition of Subscription Shares set forth above in this Section shall not apply to any disposition of such shares following the death of the person to whom such shares were initially sold under the terms of this Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. With respect to all Subscription Shares subject to restrictions on resale or subsequent disposition, each of the following provisions shall apply:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Each certificate or record of ownership representing
 shares restricted by this section shall bear a legend giving notice of the restriction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Instructions shall be issued to the stock
 transfer agent for the Holding Company not to recognize or effect any transfer of any certificate
 or record of ownership of any such shares in violation of the restriction on transfer; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Any shares of capital stock of the Holding
 Company issued with respect to a stock dividend, stock split, or otherwise with respect to
 ownership of outstanding Subscription Shares subject to the restriction on transfer hereunder
 shall be subject to the same restriction as is applicable to such Subscription Shares.

**22.** **REQUIREMENTS FOR STOCK PURCHASES BY DIRECTORS AND OFFICERS FOLLOWING THE CONVERSION** 

For a period of three (3) years following the Conversion, no Officer, Director or their Associates shall purchase, without the prior written approval of the Bank Regulators, any outstanding shares of Holding Company Common Stock except from a broker-dealer registered with the SEC. This provision shall not apply to negotiated transactions involving more than 1% of the outstanding shares of Holding Company Common Stock, the exercise of any options pursuant to a stock option plan or purchases of Holding Company Common Stock made by or held by any Tax-Qualified Employee Stock Benefit Plan or Non-Tax-Qualified Employee Stock Benefit Plan of the Bank or the Holding Company (including the Employee Plans) which may be attributable to any Officer or Director. As used herein, the term "negotiated transaction" means a transaction in which the securities are offered and the terms and arrangements relating to any sale are arrived at through direct communications between the seller or any person acting on its behalf and the purchaser or his investment representative. The term "investment representative" shall mean a professional investment advisor acting as agent for the purchaser and independent of the seller and not acting on behalf of the seller in connection with the transaction.

**23.** **TRANSFER OF DEPOSIT ACCOUNTS** 

Each person holding a Deposit Account at the Bank at the time of Conversion shall retain an identical Deposit Account at the Bank following Conversion in the same amount and subject to the same terms and conditions (except as to voting and liquidation rights) applicable to such Deposit Account in the Bank immediately before the completion of the Conversion.

**24.** **REGISTRATION AND MARKETING** 

For the time period required by applicable laws and regulations, the Holding Company will register the securities issued in connection with the Conversion pursuant to the Securities Exchange Act of 1934 and will not deregister such securities for a period of at least three (3) years thereafter, except that the requirement to maintain the registration of such securities for three (3) years may be fulfilled by any successor to the Holding Company. In addition, the Holding Company will use its best efforts to encourage and assist a market-maker to establish and maintain a market for the Conversion Stock and to list those securities on a national or regional securities exchange unless otherwise permitted by the Federal Reserve.

**25.** **TAX RULINGS OR OPINIONS** 

Consummation of the Conversion is expressly conditioned upon prior receipt by the Mutual Holding Company, the Mid-Tier Holding Company, the Holding Company and the Bank of either a ruling, an opinion of counsel or a letter of advice from their tax advisors regarding the federal and state income tax consequences of the Conversion to the Mutual Holding Company, the Mid-Tier Holding Company, the Holding Company, the Bank and the Account Holders and Voting Members receiving subscription rights in the Conversion.

**26.** **STOCK BENEFIT PLANS AND EMPLOYMENT AGREEMENTS** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. The Holding Company and the Bank are authorized to adopt Tax-Qualified Employee Stock Benefit Plans in connection with the Conversion, including without limitation, an ESOP. Existing as well as any newly created Tax-Qualified Employee Stock Benefit Plans may purchase shares of Holding Company Common Stock in the Offering, to the extent permitted by the terms of such benefit plans and this Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. As a result of the Conversion, the Holding Company shall be deemed to have ratified and approved all employee stock benefit plans maintained by the Bank and the Mid-Tier Holding Company and shall have agreed to issue (and reserve for issuance) Holding Company Common Stock in lieu of common stock of the Mid-Tier Holding Company pursuant to the terms of such benefit plans. Upon consummation of the Conversion, the Mid-Tier Holding Company common stock held by such benefit plans shall be converted into Holding Company Common Stock based upon the Exchange Ratio. Also upon consummation of the Conversion, (i) all rights to purchase, sell or receive Mid-Tier Holding Company common stock and all rights to elect to make payment in Mid-Tier Holding Company common stock under any agreement between the Bank or the Mid-Tier Holding Company and any Director, Officer or Employee thereof or under any plan or program of the Bank or the Mid-Tier Holding Company, shall automatically, by operation of law, be converted into and shall become an identical right to purchase, sell or receive Holding Company Common Stock and an identical right to make payment in Holding Company Common Stock under any such agreement between the Bank or the Mid-Tier Holding Company and any Director, Officer or Employee thereof or under such plan or program of the Bank, and (ii) rights outstanding under all stock option plans shall be assumed by the Holding Company and thereafter shall be rights only for shares of Holding Company Common Stock, with each such right being for a number of shares of Holding Company Common Stock based upon the Exchange Ratio and the number of shares of Mid-Tier Holding Company common stock that were available thereunder immediately before the consummation of the Conversion, with the price adjusted to reflect the Exchange Ratio but with no change in any other term or condition of such right.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;C. The Holding Company and the Bank are authorized to adopt stock option plans, restricted stock award plans and other Non-Tax-Qualified Employee Stock Benefit Plans, provided that such plans conform to any applicable regulations. The Holding Company and the Bank intend to implement a stock option plan and a restricted stock award plan no earlier than six months after completion of the Conversion. Stockholder approval of these plans will be required. If adopted within twelve (12) months following the completion of the Conversion, the stock option plan will reserve a number of shares equal to up to 10% of the shares sold in the Offering and the stock award plan will reserve a number of shares equal to up to 4% of the shares sold in the Offering for awards to employees and directors at no cost to the recipients (unless the Bank's tangible capital is less than 10% upon completion of the Offering in which case the stock award plan will reserve a number of shares equal to up to 3% of the shares sold in the Offering), subject to adjustment, if any, as may be required by Federal Reserve regulations or policy in effect to reflect stock options or restricted stock granted by the Mid-Tier Holding Company before the completion of the Conversion. (Stock option plans, restricted stock award plans, as well as Non-Tax-Qualified Employee Stock Benefit Plans, implemented more than one (1) year following the completion of the Conversion are not subject to the restrictions set forth in the preceding sentence.) Shares for such plans may be issued from authorized but unissued shares, treasury shares or repurchased shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;D. The Holding Company and the Bank are authorized to enter into employment agreements and/or change in control agreements with their executive officers.

**27.** **RESTRICTIONS ON ACQUISITION OF BANK AND HOLDING COMPANY** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. For a period of three (3) years from the date of consummation of the Conversion, no person shall directly or indirectly offer to acquire or acquire the beneficial ownership of more than 10% of any class of equity security of the Holding Company without the prior written consent of the Federal Reserve. Nothing in this Plan shall prohibit the Holding Company from taking actions permitted under 12 C.F.R. 239.63(f).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. The Articles of Incorporation of the Holding Company may contain a provision stipulating that in no event shall any record owner of any outstanding shares of Holding Company Common Stock who beneficially owns in excess of 10% of such outstanding shares be entitled or permitted to vote any shares held in excess of 10% of the Holding Company's outstanding shares. In addition, the Articles of Incorporation and Bylaws of the Holding Company may contain provisions that provide for, or prohibit, as the case may be, staggered terms of the directors, qualifications for directors, noncumulative voting for directors, limitations on the calling of special meetings, a fair price provision for certain business combinations and certain notice requirements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A. The Holding Company shall comply with applicable regulations in the repurchase of any shares of its capital stock following consummation of the Conversion. The Holding Company shall not declare or pay a cash dividend on, or repurchase any of, its capital stock, if such dividend or repurchase would reduce its capital below the amount then required for the Liquidation Account.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;B. The Bank shall not declare or pay a cash dividend on, or repurchase any of, its capital stock if the effect thereof would cause its regulatory capital to be reduced below its applicable regulatory capital requirements or below the amount then required for the Bank Liquidation Account.

**29.** **ARTICLES OF INCORPORATION AND BYLAWS** 

By voting to approve this Plan, Voting Members and Stockholders shall be voting to adopt the Articles of Incorporation and Bylaws of the Holding Company.

**32.** **AMENDMENT OR TERMINATION OF PLAN** 

If deemed necessary or desirable, this Plan may be substantively amended as a result of comments from the Bank Regulators or otherwise at any time before the meetings of Voting Members and Stockholders to vote on this Plan by the Board of Directors of the Mutual Holding Company, and at any time thereafter by the Board of Directors of the Mutual Holding Company with the concurrence of the Bank Regulators. Any amendment to this Plan made after approval by Voting Members and Stockholders with the approval of the Bank Regulators shall not necessitate further approval by Voting Members or Stockholders unless otherwise required by the Bank Regulators.

Each share of common stock, par value $0.01 per share, of Northfield (the "<u>Northfield Common Stock</u>") issued and outstanding immediately prior to the Effective Time, including shares of Northfield Restricted Stock and Northfield PRSUs, (other than shares cancelled and retired or converted pursuant to <u>Section 2.1(a)</u>, and other than Dissenting Shares shall be converted, at the election of the holder thereof in accordance with the procedures set forth in <u>Section 2.2</u> and <u>Section 2.3</u> into the right to receive either shares of Newco Common Stock (the "<u>Stock Consideration"</u>) or cash (the "<u>Cash Consideration"</u>), without interest, as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) if the Independent Valuation immediately prior to the closing of the Conversion (the "<u>Final Independent Valuation"</u>) is less than $2,300,000,000, (a) 1.425 shares of Newco Common Stock (the "<u>Merger Exchange Ratio"</u>) for each share of Northfield Common Stock with respect to which an election to receive Newco Common Stock has been effectively made and not revoked pursuant to <u>Section 2.3</u> (a "<u>Stock Election"</u> and collectively the "<u>Stock Election Shares"</u>) or (b) $14.25 in cash for each share of Northfield Common Stock (the "<u>Per Share Cash Consideration"</u>) with respect to which an election to receive cash has been effectively made and not revoked pursuant to <u>Section 2.3</u> (a "<u>Cash Election</u>" and collectively the "<u>Cash Election Shares</u>");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) if the Final Independent Valuation is equal to or greater than $2,300,000,000 and less than $2,600,000,000, (a) the Merger Exchange Ratio shall be increased to 1.450 shares of Newco Common Stock for each share of Northfield Common Stock subject to a Stock Election and (b) the Per Share Cash Consideration shall be increased to $14.50 for each share of Northfield Common Stock subject to a Cash Election; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) if the Final Independent Valuation is equal to or greater than $2,600,000,000, (a) the Merger Exchange Ratio shall be increased to 1.465 shares of Newco Common Stock for each share of Northfield Common Stock subject to a Stock Election and (b) the Per Share Cash Consideration shall be increased to $14.65 for each share of Northfield Common Stock subject to a Cash Election.

Holders of shares of Northfield Common Stock that have not made a valid Cash Election or Stock Election pursuant to <u>Section 2.3</u> are sometimes referred to herein as "<u>Non-Election Shares</u>") will receive Cash Consideration or Stock Consideration, as determined in the sole discretion of Newco, subject to the provisions of <u>Section 2.2(b)</u>. The Cash Consideration and Stock Consideration are sometimes referred to herein collectively as the "<u>Merger Consideration</u>."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) <u>Effect of Conversion of Northfield Common Stock</u>. All of the shares of Northfield Common Stock converted into the right to receive the Merger Consideration pursuant to this <u>Section 2.1</u> shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time, and each certificate (each, a "Certificate," it being understood that any reference herein to "Certificate" shall be deemed to include reference to book entry account statements relating to the ownership of shares of Northfield Common Stock) previously representing any such shares of Northfield Common Stock shall thereafter represent only the right to receive for each such share of Northfield Common Stock (i) the Merger Consideration, (ii) cash in lieu of fractional shares which the shares of Northfield Common Stock represented by such Certificate have been converted into pursuant to this <u>Section 2.1</u> and <u>Section 2.2(l)</u>, without any interest thereon and (iii) any dividends or distributions which the holder thereof has, in each case, without any interest thereon.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) <u>Certain Adjustments</u>. If, prior to the Effective Time, the outstanding shares of Columbia Common Stock or Northfield Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split or reverse stock split or other similar structural change in capitalization, or there shall be any extraordinary dividend or distribution, an appropriate and proportionate adjustment shall be made to the Merger Exchange Ratio and/or the Per Share Cash Consideration to give Columbia and the holders of shares of Northfield Common Stock the same economic effect as contemplated by this Agreement prior to such event; provided that nothing contained in this sentence shall be construed to permit Northfield or Columbia to take any action with respect to its securities or otherwise that is prohibited by the terms of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.2 <u>Proration</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Notwithstanding any other provision contained in this Agreement the number of shares of Northfield Common Stock to be converted into the Cash Consideration (the "<u>Cash Conversion Number</u>") shall be no greater than the product obtained by multiplying (x) the number of shares of Northfield Common Stock issued and outstanding as of the Effective Time (excluding shares of Northfield Common Stock to be canceled as provided in <u>Section 2.1(a))</u> by (y) 0.30, it being understood that all of the other shares of Northfield Common Stock shall be converted into Stock Consideration (in each case excluding shares of Northfield Common Stock to be canceled as provided in <u>Section 2.1(a)</u> and Dissenting Shares); <u>provided</u>, <u>however</u>, if either of the tax opinions referred to in <u>Section 7.2(d)</u> or <u>7.3(d)</u> cannot be rendered (as reasonably determined, in each case, by the counsel charged with giving such opinion) as a result of the Merger potentially failing to satisfy the "continuity of interest" requirements under applicable federal income tax principles relating to reorganizations under Section 368(a) of the Code, Newco shall reduce the number of shares of Northfield Common Stock entitled to receive the Cash Consideration and correspondingly increase the number of shares of Northfield Common Stock entitled to receive the Stock Consideration by the minimum amount necessary to enable the Merger to satisfy such continuity of interest requirement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Within five (5) business days after the Effective Time, Newco shall cause the Exchange Agent to effect the allocation among holders of Northfield Common Stock of the right to receive the Cash Consideration and the Stock Consideration as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) If the number of Cash Election Shares is greater than the Cash Conversion Number, then:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) all Stock Election Shares, and such number of Non-Election Shares as determined in the sole discretion of Newco, shall be converted into the right to receive the Stock Consideration such that the number of Cash Election Shares to be converted does not exceed the Cash Conversion Number; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) the Cash Election Shares of each holder thereof shall be converted into the right to receive the Stock Consideration in respect of that number of Cash Election Shares (rounded to the nearest whole share) equal to the product obtained by multiplying (x) the number of Cash Election Shares held by such holder by (y) a fraction, the numerator of which is the amount by which the Cash Election Shares exceed the Cash Conversion Number and the denominator of which is the total number of Cash Election Shares, with the remaining number of each such holder's Cash Election Shares being converted into the right to receive the Cash Consideration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) If the number of Cash Election Shares is equal to or less than the Cash Conversion Number, then all Cash Election Shares shall be converted into the right to receive the Cash Consideration and all Stock Election Shares, and such number of Non-Election Shares as determined in the sole discretion of Newco, shall be converted into the right to receive the Stock Consideration, subject to the Cash Conversion Number.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.3 <u>Election and Exchange Procedures</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Each holder of Northfield Common Stock may specify in a request made in accordance with the provisions of this <u>Section 2.3</u> (herein called an "<u>Election</u>") (x) the number of shares of Northfield Common Stock owned by such holder with respect to which such holder of Northfield Common Stock desires to make a Stock Election and (y) the number of shares of Northfield Common Stock owned by such holder of Northfield Common Stock with respect to which such holder of Northfield Common Stock desires to make a Cash Election.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Newco shall prepare a form reasonably acceptable to Northfield (the "<u>Form of Election</u>") which shall be mailed to Northfield's stockholders entitled to vote at the Northfield Meeting so as to permit stockholders of Northfield to exercise their right to make an Election prior to the Election Deadline.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Form of Election shall be mailed to each holder of Northfield Common Stock on or about the time the Joint Proxy Statement/Prospectus is mailed to Northfield stockholders entitled to vote (the "<u>Mailing Date</u>") and shall use all reasonable efforts to make available as promptly as possible a Form of Election to any stockholder of Northfield who requests such Form of Election following the Mailing Date and prior to the Election Deadline.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Any Election shall have been made properly only if the person authorized to receive Elections and to act as Exchange Agent under this Agreement, which person shall be designated by Newco and reasonably acceptable to Northfield (the "<u>Exchange Agent</u>"), pursuant to an agreement entered into prior to Closing shall have received, by 5:00 p.m. local time in the city in which the principal office of such Exchange Agent is located, on the date of the Election Deadline a Form of Election properly completed and signed accompanied by the Certificates representing Northfield Common Stock as to which such Form of Election is being made or by an appropriate guarantee of delivery of such Certificates, as set forth in the Form of Election, it being understood no Certificate need be delivered for Northfield stockholders who hold shares in book-entry form. As used herein, "<u>Election Deadline</u>" means 5:00 p.m. on the date that as reasonably determined by Newco is as close as possible to the fifth business day prior to date on which the Closing occurs. Northfield and Newco shall cooperate to issue a press release reasonably satisfactory to each of them announcing the date of the Election Deadline not more than twenty (20) business days before and at least ten (10) business days prior to the Election Deadline.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) Any stockholder of Northfield may, at any time prior to the Election Deadline, change or revoke his or her Election by written notice received by the Exchange Agent prior to the Election Deadline accompanied by a properly completed and signed, revised Form of Election. If Newco, after consultation with the Exchange Agent, shall determine in its reasonable discretion that any Election is not properly made with respect to any shares of Northfield Common Stock, such Election shall be deemed to be not in effect, and the shares of Northfield Common Stock covered by such Election shall, for purposes hereof, be deemed to be Non-Election Shares, unless a proper Election is thereafter timely made.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) All Elections shall be revoked automatically if the Exchange Agent is notified in writing by Newco or Northfield that this Agreement has been terminated in accordance with <u>Article VIII</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) If any portion of the Merger Consideration is to be paid to a person other than the person in whose name a Certificate surrendered pursuant to <u>Section 2.3(i)</u> is registered, it shall be a condition to such payment that such Certificate shall be properly endorsed or otherwise be in proper form for transfer, as applicable, and the person requesting such payment shall inform the Exchange Agent, pursuant to an agreement entered into prior to Closing, whether any transfer or other similar Taxes are required as a result of such payment to a person other than the registered holder of such Certificate, or establish to the reasonable satisfaction of the Exchange Agent that such Taxes are not payable. If such transfer or other similar Taxes are payable pursuant to the preceding sentence, then the Exchange Agent shall withhold and deduct from the Merger Consideration (including cash in lieu of fractional shares of Newco Common Stock) otherwise payable pursuant to this Agreement to the designated person other than the registered holder such amounts as the Exchange Agent determines is necessary based on the information supplied by the registered holder. The Exchange Agent (or, subsequent to the twelve-month anniversary of the Effective Time, Newco) shall be entitled to deduct and withhold from the Merger Consideration (including cash in lieu of fractional shares of Newco Common Stock) otherwise payable pursuant to this Agreement to any holder of Northfield Common Stock such amounts as the Exchange Agent or Newco, as the case may be, is required to deduct and withhold under the Code, or any provision of state, local or foreign Tax law, with respect to the making of such payment. To the extent that any amounts are withheld by the Exchange Agent or Newco, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of shares of Northfield Common Stock in respect of whom such deduction and withholding was made by the Exchange Agent or Newco, as the case may be.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) At least one (1) business day prior to the Effective Time, Newco shall deposit, or shall cause to be deposited, with the Exchange Agent, for the benefit of the holders of Northfield Common Stock pursuant to this <u>Article II</u> (i) certificates, or at Newco's option, evidence of shares in book-entry form, representing the shares of Newco Common Stock, sufficient to pay the aggregate Stock Consideration required pursuant to this <u>Article II</u>, and (ii) an aggregate amount of cash sufficient to pay the Cash Consideration and the estimated amount of cash to be paid in lieu of fractional shares of Newco Common Stock, each to be given to the holders of Northfield Common Stock in exchange for Certificates pursuant to this <u>Article II</u>. Upon the twelve (12) month anniversary of the Effective Time, any such cash or certificates remaining in the possession of the Exchange Agent, together with any earnings in respect thereof, shall be delivered to Newco. Any holder of Certificates who has not theretofore exchanged his or her Certificates or for the Merger Consideration pursuant to this <u>Article II</u> shall thereafter be entitled to look exclusively to Newco and only as a general creditor thereof, for the Merger Consideration, as applicable, to which he or she may be entitled upon exchange of such Certificates pursuant to this <u>Article II</u>. If outstanding Certificates are not surrendered, or the payment for the Certificates is not claimed prior to the date on which such payment would otherwise escheat to or become the property of any Governmental Entity, the unclaimed items shall, to the extent permitted by abandoned property and any other applicable law, become the property of Newco (and to the extent not in its possession shall be delivered to it), free and clear of all Liens of any person previously entitled to such property. Neither the Exchange Agent nor any of the parties hereto shall be liable to any holder of Northfield Common Stock represented by any Certificate for any consideration paid to a public official pursuant to applicable abandoned property, escheat or similar laws. Newco and the Exchange Agent shall be entitled to rely upon the stock transfer books of Northfield to establish the identity of those persons entitled to receive the Merger Consideration, which books shall be conclusive with respect thereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Promptly after the Effective Time, but in no event later than five (5) business days thereafter, Newco shall cause the Exchange Agent to mail or deliver to each person who did not surrender, or who improperly surrendered, such stockholder's Certificates to the Exchange Agent and who was, immediately prior to the Effective Time, a holder of record of Northfield Common Stock a notice advising such holders of the effectiveness of the Merger, including a form of letter of transmittal in a form reasonably satisfactory to Newco and Northfield containing instructions for use in effecting the surrender of Certificates in exchange for the Merger Consideration which shall specify that delivery shall be effected, and risk of loss and title to Certificates shall pass, only upon with respect to shares evidenced by Certificates, upon proper delivery of the Certificates and the transmittal materials, duly, completely and validly executed in accordance with the instructions thereto. Upon surrender to the Exchange Agent of a Certificate for cancellation together with such letter of transmittal, duly executed and completed in accordance with the instructions thereto, the holder of such Certificate shall promptly be provided in exchange therefor, but in no event later than five (5) business days after due surrender, (x) a certificate, or at the election of Newco, a statement reflecting shares issued in book-entry form, representing the number of whole shares of Newco Common Stock that such holder is entitled pursuant to this <u>Article II</u>, and (y) a check in the amount equal to the sum of (A) the cash portion of the Merger Consideration that such holder has the right to receive in respect of such Certificate surrendered pursuant to this <u>Article II</u>, (B) any cash in lieu of fractional shares pursuant to <u>Section 2.3(l)</u> and (C) any dividends or other distributions that such holder is entitled pursuant to <u>Section 2.3(k)</u>, and the Certificate so surrendered shall forthwith be canceled. No interest will accrue or be paid with respect to any property to be delivered upon surrender of Certificates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) In the event any Certificates shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate(s) to be lost, stolen or destroyed and, if required by Newco or the Exchange Agent, the posting by such person of a bond in customary amount as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate(s), Newco shall cause the Exchange Agent to issue the Merger Consideration, and any cash, unpaid dividends or other distributions that would be payable or deliverable, in respect of the shares of Northfield Common Stock represented by such lost, stolen or destroyed Certificates.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) No dividends or other distributions with respect to Newco Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Newco Common Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to subsection (l) below, and no such dividends, other distributions and cash in lieu of fractional shares of Newco Common Stock shall be paid by Newco to the Exchange Agent, in each case until the surrender of such Certificate in accordance with subsection (l) below. Subject to the effect of applicable abandoned property, escheat or similar laws, following surrender of any such Certificate there shall be paid to the holder of the whole shares of Newco Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, (x) the cash portion of the Merger Consideration that such holder has the right to receive in respect of such Certificate surrendered pursuant to this <u>Article II</u> and (y) the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Newco Common Stock and the amount of any cash payable in lieu of a fractional share of Newco Common Stock to which such holder is entitled pursuant to subsection (l), and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and with a payment date subsequent to such surrender payable with respect to such whole shares of Newco Common Stock. Newco shall make available to the Exchange Agent cash for these purposes, if necessary.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) Notwithstanding any other provision hereof, no fractional shares of Newco Common Stock and no certificates or scrip therefor, or other evidence of ownership thereof, will be issued in the Merger; no dividend or distribution by Newco shall relate to such fractional share interests; and such fractional share interests will not entitle the owner thereof to vote or to any rights as a stockholder of Newco. In lieu of any such fractional shares, Newco shall pay to each holder of a fractional share of Newco Common Stock an amount of cash (without interest) determined by multiplying the Per Share Cash Consideration by the fraction of a share of Newco Common Stock which such holder would otherwise be entitled to receive pursuant to <u>Section 2.1(b)(ii)</u> above. No interest will be paid on the cash that the holders of such fractional shares shall be entitled to receive upon such delivery. Notwithstanding any other provision contained in this Agreement, funds utilized to acquire fractional shares as aforesaid shall be furnished by Newco on a timely basis and shall in no event be derived from or diminish the Cash Consideration available for distribution as part of the Merger Consideration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.4 <u>Treatment of Northfield Equity Awards</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) *Treatment of Stock Options*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Effective as of the Effective Time, each option to purchase a share of Northfield Stock ("<u>Northfield Option</u>"), whether vested or unvested, that is outstanding as of immediately prior to the Effective Time, shall fully vest and cease to represent a right to acquire shares of Northfield Common Stock and shall be converted automatically, without any required action on the part of Northfield or any holder of such Northfield Option, into an option to purchase shares of Newco Common Stock in an amount and at an exercise price determined as provided below. Newco shall assume each Northfield Option, and, thereafter, each such assumed Northfield Option shall continue to be subject to the terms of the applicable Northfield Equity Plan or other agreement by which it is evidenced, except that from and after the Effective Time, (i) the Compensation Committee of Newco shall be substituted for the committee of the Northfield board of directors administering such Northfield Equity Plan, (ii) the number of shares of Newco Common Stock subject to such Northfield Option shall be equal to the number of shares of Northfield Common Stock subject to such Northfield Option immediately prior to the Effective Time multiplied by the Merger Exchange Ratio, provided that any fractional shares of Newco Common Stock resulting from such multiplication shall be rounded down to the nearest share and (iii) the per share exercise price under each such Northfield Option shall be adjusted by dividing the per share exercise price under each such Northfield Option by the Merger Exchange Ratio, provided that such exercise price shall be rounded up to the nearest cent. Notwithstanding clauses (ii) and (iii) of the immediately preceding sentence, each Northfield Option which is an "incentive stock option" shall be adjusted as required by Sections 409A and 424 of the Code, and the regulations and guidance promulgated thereunder, so as not to constitute a modification, extension or renewal of the option within the meaning of Sections 409A and 424(h) of the Code. Newco and Northfield agree to take all necessary steps to effect the foregoing provisions of this <u>Section 2.4(a)(i)</u>, including in the case of Newco taking all corporate action necessary to reserve for issuance a sufficient number of shares of Newco Common Stock for delivery upon exercise of the options to issue shares of Newco Common Stock issued in accordance herewith.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) As soon as practicable after the Effective Time, Newco shall use its reasonable efforts to file a registration statement on Form S-8 (or any successor or other appropriate forms), with respect to the shares of Newco Common Stock subject to the options referred to in <u>Section 2.4(a)(i)</u> and shall use its reasonable efforts to maintain the current status of the prospectus or prospectuses contained therein for so long as such options remain outstanding in the case of a Form S-8.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) With respect to those individuals who, subsequent to the Merger, will be subject to the reporting requirements under Section 16(a) of the Exchange Act, where applicable, Newco shall administer the Northfield Equity Plans in a manner consistent with the exemptions provided by Rule 16b-3 promulgated under the Exchange Act.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) *Treatment of Restricted Stock Awards*. Immediately prior to the Effective Time, any vesting or other forfeiture restrictions on each share of Northfield Common Stock subject to time-based vesting ("<u>Northfield Restricted Stock</u>") outstanding as of immediately prior to the Effective Time shall automatically and without any required action on the part of the holder thereof, lapse, Northfield Restricted Stock will fully vest and shall be treated as an issued and outstanding shares of Northfield Common Stock for the purposes of this Agreement. For the avoidance of doubt, Newco shall not assume any Northfield Restricted Stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) *Treatment of Performance-Based Restricted Stock Units*. Immediately prior to the Effective Time, each award of performance-based restricted stock units with respect to Northfield Common Stock ("<u>Northfield PRSUs</u>") outstanding immediately prior to the Effective Time shall automatically and without any required action on the part of the holder thereof, accelerate in full and fully vest, with any applicable performance-based vesting condition to be deemed achieved at the greater of the target level of performance or actual annualized performance measured as of the most recent completed fiscal quarter and shall be treated as an issued and outstanding share of Northfield Common Stock for the purposes of this Agreement. For the avoidance of doubt, Newco shall not assume any Northfield PRSUs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) *Additional Actions.* Prior to the Effective Time, Northfield shall take all actions that may be necessary or required (under any Northfield Equity Plan, any applicable law, the applicable award agreements or otherwise) (i) to effectuate the provisions of this <u>Section 2.4</u> and (ii) to ensure that, from and after the Effective Time, holders of Northfield Restricted Stock, and Northfield PRSUs shall have no rights with respect to thereto other than those rights specifically provided in this <u>Section 2.4</u>, if any.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.5 <u>Rights as Stockholders; Stock Transfers.</u> All shares of Northfield Common Stock, when converted as provided in <u>Section 2.1</u> shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist and, except as to Treasury Stock, each Certificate previously evidencing such shares shall thereafter represent only the right to receive, for each such share of Northfield Common Stock, the Merger Consideration and, if applicable, any cash in lieu of fractional shares of Newco Common Stock in accordance with <u>Section 2.3</u>. At the Effective Time, holders of Northfield Common Stock shall cease to be, and shall have no rights as, stockholders of Northfield, other than the right to receive the Merger Consideration and cash in lieu of fractional shares of Newco Common Stock as provided under <u>Section 2.1</u> and this <u>Section 2.5</u>. After the Effective Time, there shall be no transfers on the stock transfer books of Northfield of shares of Northfield Common Stock, other than transfers of Northfield Common Stock that have occurred prior to the Effective Time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.6 <u>Adjustments to Preserve Tax Treatment</u>. If either the opinion referred to in <u>Section 7.2(d)</u> or the opinion referred to in <u>Section 7.3(d)</u> cannot be rendered (as reasonably determined, in each case, by the counsel charged with giving such opinion) as a result of the Merger potentially failing to satisfy the "continuity of interest" requirements under applicable U.S. federal income tax principles relating to reorganizations under Section 368(a) of the Code, then Newco shall reduce the number of shares of Northfield Common Stock entitled to receive the Cash Consideration and correspondingly increase the number of shares of Northfield Common Stock entitled to receive the Stock Consideration by the minimum amount necessary to enable the Merger to satisfy such continuity of interest requirement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.7 <u>Statutory Rights of Appraisal</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Notwithstanding anything in this Agreement to the contrary, if required by the DGCL (but only to the extent required thereby), shares of Northfield Common Stock that are issued and outstanding immediately prior to the Effective Time and which are held by any Holder who has not voted in favor of the adoption of this Agreement or consented thereto in writing and who is entitled to and has properly demanded appraisal rights with respect thereto in accordance with, Section 262 of the DGCL and not effectively withdrawn such demand with respect to any such Northfield Common Stock held by any such holder (the "<u>Dissenting Shares</u>") shall not be converted into the right to receive any of the Merger Consideration as specified in this Agreement. Such holders shall be entitled to receive payment of the appraised value of such Dissenting Shares in accordance with the provisions of Section 262 of the DGCL except that all Dissenting Shares held by holders who shall have failed to perfect or who shall have effectively withdrawn or lost their rights to appraisal of such Dissenting Shares pursuant to Section 262 of the DGCL will thereupon be deemed to have been converted into, and to have become exchangeable for, as of the Effective Time, the right to receive the Merger Consideration in accordance with <u>Section 2.1(c)</u> of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Northfield shall give Newco prompt written notice (but in any event within 48 hours) to Newco of any demands for payment in respect of any shares of Northfield Common Stock and any withdrawals of such demands, and any other instruments served pursuant to law with respect to appraisal rights, and Newco shall have the right to participate in and direct all negotiations and proceedings with respect to such demands. Northfield shall not, except with the prior written consent of Newco, voluntarily make, or commit or agree to make, any payment with respect to, or settle, or offer or agree to settle, any such demand for payment.

Without limiting the generality of the foregoing, as soon as practicable and in no event later than forty-five (45) days after the date of this Agreement, the Columbia Parties and Northfield shall, and shall cause their respective Subsidiaries to, each prepare and file any applications, notices and filings required to be filed with any bank regulatory agency in order to obtain the Requisite Regulatory Approvals. The Columbia Parties and Northfield shall each use, and shall each cause their applicable Subsidiaries to use, reasonable best efforts to obtain each such Requisite Regulatory Approval as promptly as reasonably practicable. The Columbia Parties and Northfield shall have the right to review and provide comments in advance, and, to the extent practicable, each will consult the other on, in each case subject to applicable laws relating to the exchange of information, all the information relating to Northfield or any of the Columbia Parties, as the case may be, and any of their respective Subsidiaries, which appears in any filing made with, or written materials submitted to, any third party or any Governmental Entity in connection with the transactions contemplated by this Agreement; <u>provided</u> that Northfield shall not have the right to review portions of materials filed by any of the Columbia Parties or Columbia Bank with a Governmental Entity that contain confidential supervisory information.

As used in this Agreement, the term "<u>Requisite Regulatory Approvals</u>" shall mean all permits, consents, orders, approvals, waivers, non-objections and authorizations (and the expiration or termination of all statutory waiting periods in respect thereof) from (i) the Federal Reserve Board under the HOLA, the BHC Act, the Bank Merger Act and the Riegle-Neal Act, (ii) if required by the HSR Act, under the HSR Act and (iii) from any Governmental Entity (x) necessary to consummate the transactions contemplated by this Agreement (including the Conversion, the Merger and the Bank Mergers) or (y) the non-receipt of which would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on the Surviving Corporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Each party shall use its reasonable best efforts to respond to any requests for information from and to resolve any objection that may be asserted by any Governmental Entity with respect to this Agreement or the transactions contemplated hereby, including the Conversion.

Neither any of the Columbia Parties nor Northfield, nor any of their respective Subsidiaries, shall be required to provide (x) any portion of board and committee minutes that discuss any of the transactions contemplated by this Agreement or (y) access to or to disclose information where such access or disclosure would violate or prejudice the rights of any of the Columbia Parties or Northfield, as the case may be, customers, jeopardize the attorney-client privilege of the institution in possession or control of such information (after giving due consideration to the existence of any common interest, joint defense or similar agreement between the parties) or contravene any law, rule, regulation, order, judgment, decree, fiduciary duty or binding agreement entered into prior to the date of this Agreement. The parties hereto will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Each of the Columbia Parties and Northfield shall hold all information furnished by or on behalf of the other party or any of such party's Subsidiaries or Representatives pursuant to this Agreement in confidence to the extent required by, and in accordance with, the provisions of the confidentiality agreement, dated December 12, 2025, by and between Columbia and Northfield (as it may be amended in accordance with its terms) (the "<u>Confidentiality Agreement</u>").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) No investigation by either of the parties or their respective Representatives shall affect or be deemed to modify or waive the representations, warranties, covenants and agreements of the other set forth herein. Nothing contained in this Agreement shall give either party, directly or indirectly, the right to control or direct the operations of the other party prior to the Effective Time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.3 <u>Stockholder Approvals</u>. Each of Columbia and Northfield shall call, give notice of, establish a record date for, convene and hold a meeting of its respective stockholders (the "<u>Columbia Meeting</u>" and the "<u>Northfield Meeting</u>," respectively) to be held as soon as reasonably practicable after the Form S-4 is declared effective, for the purpose of obtaining (i) in the case of Northfield, the Requisite Northfield Vote, and in the case of Columbia, the Requisite Columbia Vote, and (ii) if so desired and mutually agreed, a vote upon other matters of the type customarily brought before a meeting of stockholders in connection with the approval of a merger agreement or the transactions contemplated thereby, and each of Northfield and Columbia shall use its reasonable best efforts to cause such meetings to occur as soon as reasonably practicable and on the same date. Subject to the remainder of this <u>Section 6.3</u>, each of Columbia and Northfield and their respective Boards of Directors shall use its reasonable best efforts to obtain from the respective stockholders of Columbia and Northfield, as applicable, the Requisite Columbia Vote and the Requisite Northfield Vote, as applicable, including by communicating to the stockholders of Columbia and Northfield, as applicable, its recommendation (and including such recommendation in the Joint Proxy Statement/Prospectus) that, in the case of Columbia, the stockholders of Columbia adopt and approve this Agreement and the transactions contemplated hereby (the "<u>Columbia Board Recommendation</u>"), and, in the case of Northfield, the stockholders of Northfield adopt and approve this Agreement and the transactions contemplated hereby (the "<u>Northfield Board Recommendation</u>"). Subject to the remainder of this <u>Section 6.3,</u> each of Columbia and Northfield and their respective Boards of Directors shall not (i) withhold, withdraw, modify or qualify in a manner adverse to the other party the Columbia Board Recommendation, in the case of Columbia, or the Northfield Board Recommendation, in the case of Northfield, (ii) fail to make the Columbia Board Recommendation, in the case of Columbia, or the Northfield Board Recommendation, in the case of Northfield, in the Joint Proxy Statement/Prospectus, (iii) adopt, approve, recommend or endorse an ("<u>Acquisition Proposal</u>") or publicly announce an intention to adopt, approve, recommend or endorse an Acquisition Proposal, (iv) fail to publicly and without qualification (A) recommend against any Acquisition Proposal or (B) reaffirm the Columbia Board Recommendation, in the case of Columbia, or the Northfield Board Recommendation, in the case of Northfield, in each case within ten (10) business days (or such fewer number of days as remains prior to the Columbia Meeting or the Northfield Meeting, as applicable) after an Acquisition Proposal is made public or any request by the other party to do so, or (v) publicly propose to do any of the foregoing (any of the foregoing a "<u>Recommendation Change</u>"). However, subject to <u>Section 8.1</u> and <u>Section 8.2</u>, if the Board of Directors of Columbia or Northfield, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that it would more likely than not result in a violation of its fiduciary duties under applicable law to make or continue to make the Columbia Board Recommendation or the Northfield Board Recommendation, as applicable, such Board of Directors may, in the case of Columbia, prior to the receipt of the Requisite Columbia Vote, and in the case of Northfield, prior to the receipt of the Requisite Northfield Vote, effect a Recommendation Change, including by submitting this Agreement to its respective stockholders, without recommendation (although the resolutions approving this Agreement as of the date hereof may not be rescinded or amended), in which event such Board of Directors may communicate the basis for such Recommendation Change to its stockholders in the Joint Proxy Statement/Prospectus or an appropriate amendment or supplement thereto to the extent required by law; <u>provided</u> that such Board of Directors may not take any actions under this sentence unless it (A) gives the other party at least three (3) business days' prior written notice of its intention to take such action and a reasonable description of the event or circumstances giving rise to its determination to take such action (including, in the event such action is taken in response to an Acquisition Proposal, the latest material terms and conditions and the identity of the third party in any such Acquisition Proposal, or any amendment or modification thereof, or describe in reasonable detail such other event or circumstances) and (B) at the end of such notice period, takes into account any amendment or modification to this Agreement proposed by the other party and, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that it would nevertheless more likely than not result in a violation of its fiduciary duties under applicable law to make or continue to make the Columbia Board Recommendation or Northfield Board Recommendation, as the case may be. Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of this <u>Section 6.3</u> and will require a new notice period as referred to in this <u>Section 6.3</u>. Neither Columbia nor Northfield shall adjourn or postpone the Columbia Meeting or the Northfield Meeting, as the case may be, except that Columbia or Northfield (1) shall be permitted to adjourn or postpone the Columbia Meeting or the Northfield Meeting, as the case may be, to allow reasonable additional time for the filing and mailing of any supplemental or amended disclosure which the Board of Directors of Columbia or the Board of Directors of Northfield, as the case may be, has determined in good faith after consultation with outside counsel is necessary under applicable law and for such supplemental or amended disclosure to be disseminated and reviewed by such party's stockholders, prior to the Columbia Meeting or the Northfield Meeting, as the case may be and (2) shall adjourn or postpone the Columbia Meeting or the Northfield Meeting, as the case may be, up to two (2) times, if, as of the time for which such meeting is originally scheduled there are insufficient shares of Columbia common stock or Northfield Common Stock, as the case may be, represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting, or if on the date of such meeting Northfield or Columbia, as applicable, has not received proxies representing a sufficient number of shares necessary to obtain the Requisite Northfield Vote or the Requisite Columbia Vote; <u>provided</u> that, without the prior written consent of the other party, neither Columbia nor Northfield shall adjourn or postpone the Columbia Meeting or the Northfield Meeting, as the case may be, under this clause (2) for more than five (5) business days in the case of any individual adjournment or postponement or more than twenty (20) business days in the aggregate. If the Northfield Meeting or the Columbia Meeting is adjourned or postponed, Columbia or Northfield, respectively, may elect to cause the Columbia Meeting or the Northfield Meeting, respectively, to also be adjourned such that the meetings occur on the same date. Notwithstanding anything to the contrary herein, unless this Agreement has been terminated in accordance with its terms, (x) the Columbia Meeting shall be convened and this Agreement shall be submitted to the stockholders of Columbia at the Columbia Meeting and (y) the Northfield Meeting shall be convened and this Agreement shall be submitted to the stockholders of Northfield at the Northfield Meeting, and nothing contained herein shall be deemed to relieve either Columbia or Northfield of such obligation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.4 <u>Legal Conditions to Merger</u>. Subject in all respects to <u>Section 6.1</u> of this Agreement, each of the Columbia Parties and Northfield shall, and shall cause its Subsidiaries to, use their reasonable best efforts (a) to take, or cause to be taken, all actions necessary, proper or advisable to comply promptly with all legal requirements that may be imposed on such party or its Subsidiaries with respect to the Merger and the Bank Merger and, subject to the conditions set forth in <u>Article VII</u> hereof, to consummate the transactions contemplated by this Agreement, and (b) to obtain (and to cooperate with the other party to obtain) any material consent, authorization, order or approval of, or any exemption by, any Governmental Entity and any other third party that is required to be obtained by Northfield or any of the Columbia Parties or any of their respective Subsidiaries in connection with the Merger and the Bank Merger and the other transactions contemplated by this Agreement, including the Conversion.

Each individual who is employed by Northfield or any Northfield Subsidiary as of immediately prior to the Effective Time and continues to be actively employed by Columbia (or any affiliate thereof) after the Effective Time ("<u>Continuing Employee</u>") shall be employed under the following terms: (1) the 2026 base compensation paid to the Continuing Employee for the job offered by Columbia will equal the base compensation paid to Columbia employees serving in the same or a similar position to job offered to the Continuing Employee and with similar skill sets for the job offered as of the Effective Time; and (2) for 2026, the target cash incentive opportunity (as a percentage of base salary) for the Continuing Employee for the period beginning on the Effective Time and ending at the end of the Columbia 2026 fiscal year will be equal to the Northfield 2026 target cash incentive opportunity (as a percentage of base compensation), <u>provided</u>, <u>however</u>, all performance metrics and weightings will be determined by Columbia and set forth in a Columbia scorecard, consistent with the terms and conditions of the Columbia Performance Annual Incentive Plan (the "<u>Columbia PAIP</u>"). Effective January 1, 2027, such Continuing Employees would participate in the Columbia PAIP at such target levels, performance metrics and weightings as approved in the 2027 Columbia PAIP. It is understood and agreed that nothing in this <u>Section 6.6(a)</u> or elsewhere in this Agreement shall be deemed a contract of employment or be construed as giving Continuing Employees any rights other than as employees at will under applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In the event (i) Columbia terminates the employment (other than for circumstances reasonably constituting cause as determined by Columbia, in its sole discretion) of any Continuing Employee within six (6) months of the Closing Date; (ii) a Northfield Bank employee is not offered employment with Columbia on or before the Closing Date; or (iii) a Northfield Bank employee is offered employment with Columbia, but does not accept the employment because (A) the base compensation offered is less than the base compensation the Northfield Bank employee was receiving as of the Closing Date; or (B) the Northfield Bank employee's offer of employment is for a job located more than 35 miles from the principal location in which the Northfield Bank employee was working as of the Closing Date, the affected employee (other than employees of Northfield or Northfield Bank who are subject to an employment, change of control, severance agreement or similar agreement or to the Employee Recognition and Retention Plan (the "<u>ERRP</u>")) shall be eligible for severance benefits as follows: (A) two (2) weeks' base compensation for each full year of continuous service with Northfield (pro rata for a partial year of service), with a minimum severance benefit of four (4) weeks' base compensation and a maximum severance benefit of twenty six (26) weeks' base compensation; or (B) in the event employment is terminated thereafter, in accordance with the then existing severance policy of Columbia or its successor; provided, however, that Columbia' obligation to pay severance to any Northfield Continuing Employee pursuant to the foregoing shall be expressly conditioned on the receipt by Columbia of a separation and release agreement ("<u>Release</u>") which is provided in <u>Section 6.6(b)</u> of the Columbia Disclosure Schedule, and such Release shall not be revoked in accordance with its terms. For purposes of this <u>Section 6.6(b)</u>, "base compensation" shall be defined as set forth in <u>Section 6.6(b)</u> of the Columbia Disclosure Schedule.

Except as provided herein, Columbia shall cause each employee benefit plan or program of Columbia in which Continuing Employees are eligible to participate, including without limitation the Columbia 401(k) Plan and excluding any Columbia plan frozen to new participants, to take into account for purposes of eligibility and vesting under the employee benefit plans and programs of Columbia (but not for purposes of benefit accrual) the service of such employees with Northfield and its Subsidiaries. Service vesting shall not be recognized: (i) for purposes of the six (6) month waiting period for eligibility under the Columbia ESOP or for the Columbia ESOP allocations; or (ii) to the extent that such recognition would result in a duplication of benefits under any of the Columbia Benefit Plans or programs.

Northfield shall provide Columbia with a copy of the resolutions, plan amendments, notices and other documents prepared to effectuate the actions contemplated by this <u>Section 6.6(d)</u>, as applicable, and give Columbia a reasonable opportunity to comment on such documents (which comments shall be considered in good faith), and prior to the Closing Date, Northfield shall provide Columbia with the final documentation evidencing that the actions contemplated herein have been effectuated. Notwithstanding the foregoing, Columbia will not request the termination of the Northfield Bank Non-Qualified Deferred Compensation Plan and will assume the plan and administer the plan in accordance with its terms and any participant elections thereunder and the Northfield accrued and unused paid time off will be treated in accordance with <u>Section 6.6(d)</u> of the Columbia Disclosure Schedule.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) On the Closing Date, Northfield shall provide Columbia with a list of employees who have suffered an "employment loss" (as defined in the WARN Act) in the 90 days preceding the Closing Date or had a reduction in hours of a least fifty percent (50%) in the 180 days preceding the Closing Date, each identified by date of employment loss or reduction in hours, employing entity, and facility location.

Each Northfield Director who is appointed to the Boards of Directors of Newco and Columbia BANK shall serve on each such Board of Directors for at least four years from the Effective Time.

Notwithstanding the foregoing, in the event that after the date of this Agreement and prior to the receipt of the Requisite Northfield Vote, Northfield receives an unsolicited bona fide written Acquisition Proposal that did not result from or arise in connection with a breach of this <u>Section ‎6.12(a)</u>, Northfield may, and may permit its Subsidiaries and its and its Subsidiaries' Representatives to, furnish or cause to be furnished confidential or nonpublic information or data and participate in such negotiations or discussions with the person making the Acquisition Proposal if the Northfield Board of Directors concludes in good faith (after receiving the advice of its outside counsel, and with respect to financial matters, its financial advisors) that failure to take such actions would be more likely than not to result in a violation of its fiduciary duties under applicable law; provided, that, prior to furnishing any confidential or nonpublic information permitted to be provided pursuant to this sentence, Northfield shall have provided such information to the Columbia Parties and entered into a confidentiality agreement with the person making such Acquisition Proposal on terms no less favorable to it than the Confidentiality Agreement, which confidentiality agreement shall not provide such person with any exclusive right to negotiate with Northfield or otherwise prevent Northfield from providing any information to the Columbia Parties in accordance with this Agreement or otherwise comply with its obligations under this Agreement, and provided the Columbia Parties with at least three (3) business days prior notice of taking any such action. Northfield will, and will cause its Representatives to, (x) immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any person other than the Columbia Parties with respect to any Acquisition Proposal and (y) request the prompt return or destruction of all confidential information previously furnished to any person (other than the Columbia Parties and their Representatives) that has made or indicated an intention to make an Acquisition Proposal. Northfield will promptly (within twenty-four (24) hours) advise the Columbia Parties following receipt of any Acquisition Proposal or any request for nonpublic information or any other inquiry which could reasonably be expected to lead to an Acquisition Proposal, and the substance thereof (including the terms and conditions of and the identity of the person making such inquiry or Acquisition Proposal), will provide the Columbia Parties with an unredacted copy of any such Acquisition Proposal and any draft agreements, proposals or other materials received in connection with any such inquiry or Acquisition Proposal, and will keep the Columbia Parties apprised promptly (and in any event within twenty-four (24) hours) of any related developments, discussions and negotiations on a current basis, including any amendments to or revisions of the terms of such inquiry or Acquisition Proposal. Northfield shall use its reasonable best efforts to enforce any existing confidentiality or standstill agreements to which it or any of its Subsidiaries is a party in accordance with the terms thereof. As used in this Agreement, "Acquisition Proposal" shall mean, with respect to Northfield, other than the transactions contemplated by this Agreement, any offer, proposal or inquiry relating to, or any third-party indication of interest in, (i) any acquisition or purchase, direct or indirect, of twenty-five percent (25%) or more of the consolidated assets of Northfield and its Subsidiaries or twenty-five percent (25%) or more of any class of equity or voting securities of Northfield or its Subsidiaries whose assets, individually or in the aggregate, constitute twenty-five percent (25%) or more of the consolidated assets of Northfield, (ii) any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in such third party beneficially owning twenty-five percent (25%) or more of any class of equity or voting securities of Northfield or its Subsidiaries whose assets, individually or in the aggregate, constitute twenty-five percent (25%) or more of the consolidated assets of Northfield, or (iii) a merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving the issuance, acquisition or conversion of, or the disposition of, twenty-five percent (25%) or more of any class of equity or voting securities of Northfield or one or more of its Subsidiaries whose assets, individually or in the aggregate, constitute twenty-five percent (25%) or more of the consolidated assets of Northfield.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Nothing contained in this Agreement shall prevent Northfield or its Board of Directors from complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act or Item 1012(a) of Regulation M-A with respect to an Acquisition Proposal or from making any legally required disclosure to Northfield's stockholders; provided, that such rules will in no way eliminate or modify the effect that any action pursuant to such rules would otherwise have under this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Without limiting the foregoing, it is agreed that any violation of the restrictions set forth in this <u>Section 6.12</u> by any Subsidiary or Representative of Northfield shall constitute a breach of this <u>Section 6.12</u> by Northfield.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) Notwithstanding any other provision of this, Agreement, in the event that the Valuation Range at the Midpoint decreases by 20% or more from the Midpoint of the preliminary Valuation Range ("<u>Preliminary Midpoint</u>") provided by the Independent Appraiser at the time of first public announcement of the Merger, the parties hereby agree that: (i) Columbia may, in its sole discretion after consultation with its financial advisor, delay the Conversion Offerings; provided, however, such delayed Conversion Offerings shall close no later than the Termination Date, as defined herein; or (ii) they will engage in good faith negotiations to adjust the amount of the Merger Consideration taking into account such decrease from the Preliminary Midpoint.

The amounts payable by Northfield AND Columbia pursuant to <u>Sections 8.02(b)</u> and <u>8.02(c)</u>, respectively, and this Section 8.02(f), constitute liquidated damages and not a penalty, and except in the case of fraud or willful and material breach, shall be the sole monetary remedy of the other party in the event of a termination of this Agreement specified in such applicable section.

Each of the parties hereby further waives (a) any defense in any action for specific performance that a remedy at law would be adequate and (b) any requirement under any law to post security or a bond as a prerequisite to obtaining equitable relief.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.13 <u>Severability</u>. Whenever possible, each provision or portion of any provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision or portion of any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or portion of any provision in such jurisdiction, and this Agreement shall be reformed, construed and enforced in such jurisdiction such that the invalid, illegal or unenforceable provision or portion thereof shall be interpreted to be only so broad as is enforceable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.14 <u>Confidential Supervisory Information</u>. Notwithstanding any other provision of this Agreement, no disclosure, representation or warranty shall be made (or other action taken) pursuant to this Agreement that would involve the disclosure of confidential supervisory information (including confidential supervisory information as defined in 12 C.F.R. § 261.2(b)(1) or 12 C.F.R. § 4.32(b)(2)) of a Governmental Entity by any party to this Agreement to the extent prohibited by applicable law. To the extent legally permissible, appropriate substitute disclosures or actions shall be made or taken under circumstances in which the limitations of the preceding sentence apply.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.15 <u>Delivery by Facsimile or Electronic Transmission</u>.

WHEREAS, the Board of Directors of Northfield has unanimously determined that the Merger Agreement and the transactions contemplated thereby, including the Merger, are in the best interests of Northfield and Northfield's stockholders and declared the Merger Agreement advisable, and has resolved to recommend that Northfield's stockholders approve the Merger Agreement and submit the Merger Agreement to Northfield's stockholders for approval; and

NOW THEREFORE, in consideration of the foregoing, the mutual covenants and agreements set forth herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, intending to be legally bound, the parties hereto agree as follows:

1.  **<u>Definitions</u>.** Capitalized terms not defined in this Agreement have the meanings assigned
to those terms in the Merger Agreement.

2.  **<u>Effectiveness; Termination</u>.** This Agreement shall be effective
upon signing. This Agreement shall automatically terminate and be null and void and of no effect upon the earliest to occur of

of the parties hereto to terminate this Agreement or (c) the Effective Time; <u>provided</u> that (i) <u>Sections 11</u> through <u>17</u> hereof shall survive any such termination and (ii) such termination shall not relieve any party of any liability or damages
resulting from any willful or material breach of any of its representations, warranties, covenants or other agreements set forth herein.

3.  **<u>Support Agreement</u>.** From the date hereof until the earlier

or of a Stockholder contained in this Agreement or (2) prevent, impede, delay, interfere with, postpone, discourage or frustrate
the purposes of or adversely affect the consummation of the transactions contemplated by the Merger Agreement. Each Stockholder agrees
to exercise all voting or other determination rights such Stockholder has in any trust or other legal entity to carry out the intent and
purposes of such Stockholder's obligations in this paragraph and otherwise set forth in this Agreement. Each Stockholder represents,
covenants and agrees that, except for this Agreement, such Stockholder (x) has not entered into, and shall not enter into during

obligations under this Agreement and any revocable proxy granted to officers or directors of Northfield at the request of the Board of
Directors of Northfield in connection with election of directors or other routine matters at any annual or special meeting of the Northfield

forth herein; <u>provided</u> that nothing in this sentence will prohibit any Permitted Transfer (as defined below).

4.  **<u>Transfer Restrictions Prior to the Merger</u>.** Each Stockholder hereby agrees that such Stockholder

or indirectly, offer for sale, sell, transfer, assign, give, convey, tender in any tender or exchange offer, pledge, encumber, hypothecate
or dispose of (by merger, by testamentary disposition, by operation of law or otherwise), either voluntarily or involuntarily, enter into
any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of, or enter
into any contract, option or other arrangement or understanding with respect to the sale, transfer, assignment, conveyance, hypothecation
or other transfer or disposition of, any of the Shares, or any legal or beneficial interest therein, whether or not for value and whether
voluntary or involuntary or by operation of law (any of the foregoing, a " <u>Transfer</u> "); <u>provided</u>, that each Stockholder
may Transfer Shares (i) to any of its affiliates, as such term is defined in the Merger Agreement (" <u>Affiliates</u> "),
(ii) to any other person to whom Columbia has consented with respect to a Transfer by such Stockholder in advance in writing, (iii) to

long as the transferee, prior to the date of Transfer, agrees in a signed writing to be bound by and comply with the provisions of this
Agreement with respect to such Transferred Shares, and such Stockholder provides at least three (3) Business Days' prior written
notice (which shall include the written consent of the transferee agreeing to be bound by and comply with the provisions of this Agreement)
to Columbia, in which case such Stockholder shall remain responsible for any breach of this Agreement by such transferee, (iv) under
any existing stock sale plan adopted in accordance with Rule 10b5-1(c) (Rule 10b5-1) under the Securities Exchange Act
of 1934 for the sale of shares of Common Stock, (v) to any charitable organization that is tax exempt under Section 501(c)(3) of
the Code and (vi) to satisfy any Tax liability incurred by such Stockholder in respect of vesting, exercise or settlement of Northfield
Equity Awards held by Stockholder (any Transfer in accordance with this <u>Section 4</u>, a " <u>Permitted Transfer</u> ").
In the event of any Transfer that would qualify as a Permitted Transfer under more than one of clauses (i) through (vi), the Stockholder
effecting such Transfer may elect the clause to which such Transfer is subject for purposes of complying with this Agreement. As used
in this Agreement, the term " <u>Family Member</u> " means, with respect to each Stockholder: (I) such Stockholder and
Stockholder's spouse, individually, (II) any descendant, niece or nephew of such Stockholder or such Stockholder's spouse,
(III) any charitable organization created and primarily funded by any one or more individuals described in the foregoing (I) or

(a) such Stockholder has full legal right, capacity and authority to execute and deliver this Agreement, to perform such Stockholder's
obligations hereunder and to consummate the transactions contemplated hereby; (b) this Agreement has been duly and validly executed
and delivered by such Stockholder and constitutes a valid and legally binding agreement of such Stockholder, enforceable against such
Stockholder in accordance with its terms, and no other action is necessary to authorize the execution and delivery of this Agreement by
such Stockholder or the performance of such Stockholder's obligations hereunder; (c) the execution and delivery of this Agreement
by such Stockholder does not, and the consummation of the transactions contemplated hereby and the compliance with the provisions hereof
will not, conflict with or violate any law or result in any breach of or violation of, or constitute a default (or an event that with
notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or
cancellation of, or result in the creation of a Lien on any of the Shares pursuant to, any agreement or other instrument or obligation
binding upon such Stockholder or the Shares, nor require any authorization, consent or approval of, or filing with, any Governmental Entity
(other than an amendment to such Stockholder's Schedule 13D filed with the Securities and Exchange Commission, if any); (d) such
Stockholder beneficially owns and has the sole power to vote or direct the voting of the Shares, including all of such Stockholder's
Existing Shares as set forth on, and in the amounts set forth on,  **<u>Schedule A</u>** hereto, which as of the date hereof constitute
all of the shares of Common Stock beneficially owned by such Stockholder and over which such Stockholder, directly or indirectly, has
sole voting and dispositive authority; (e) such Stockholder beneficially owns such Stockholder's Existing Shares as set forth
on  **<u>Schedule A</u>** hereto free and clear of any proxy, voting restriction, adverse claim or other Lien (other than any restrictions

Agreement and the other agreements and documents contemplated herein and therein. Each Stockholder agrees that such Stockholder shall

under this Agreement; <u>provided</u> that nothing in this sentence will prohibit any Permitted Transfer. As used in this Agreement, the
terms " <u>beneficial owner</u>," " <u>beneficially own</u> " and " <u>beneficial ownership</u> " shall

of 1934, as amended (the " <u>Exchange Act</u> ").

6.  **<u>Publicity</u>.** Each Stockholder hereby authorizes Northfield and Columbia to publish and disclose
in any announcement or disclosure in connection with the Merger, including in the S-4, the Joint Proxy Statement/Prospectus or any other
filing with any Governmental Entity made in connection with the Merger, such Stockholder's identity and ownership of such Stockholder's
Shares and the nature of such Stockholder's obligations under this Agreement.

7.  **<u>Stock Dividends, Etc</u>.** In the event of any change in the Common Stock by reason of any reclassification,
recapitalization, reorganization, stock split (including a reverse stock split) or subdivision or combination, exchange or readjustment
of shares, or any stock dividend or stock distribution, merger or other similar change in capitalization, the term "Existing Shares"
shall be deemed to refer to and include such shares as well as all such stock dividends and distributions and any securities into which
or for which any or all of such shares may be changed or exchanged or which are received in such transaction.

8.  **<u>Entire Agreement</u>.** This Agreement and, to the extent referenced herein, the Merger Agreement
constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all other prior agreements and
understandings, both written and oral, among the parties with respect to the subject matter hereof. Nothing in this Agreement, express
or implied, is intended to or shall confer upon any person not a party to this Agreement any right, benefit or remedy of any nature whatsoever
under or by reason of this Agreement. Nothing in this Agreement shall, or shall be construed or deemed to, constitute a Transfer
of any Shares or any legal or beneficial interest in or voting or other control over any of the Shares or as creating or forming a "group"
for purposes of the Exchange Act, and all rights, ownership and benefits of and relating to the Shares shall remain vested in and belong
to each Stockholder, subject to the agreements of the parties set forth herein. This Agreement is intended to create, and creates, a contractual

The obligations of each Stockholder hereunder shall be several and not joint.

WHEREAS, subject to the terms and conditions of the Agreement and Plan of Merger (as the same may be amended, supplemented or modified, the "<u>Merger Agreement</u>"), dated as of the date hereof, by and between Columbia, Columbia Financial, Inc., a Maryland corporation ("<u>Newco</u>"), Columbia Bank MHC, a federally chartered mutual holding company, and Northfield, Northfield will be merged with and into Newco, with Newco as the surviving corporation;

WHEREAS, as of the date of this Agreement, each Stockholder owns beneficially or of record, and has the sole power to vote or direct the voting of, the shares of common stock, par value $0.01 per share, of Columbia (the "<u>Common Stock</u>") as set forth on **<u>Schedule A</u>** hereto (all such shares, the "<u>Existing Shares</u>");

WHEREAS, the Board of Directors of Columbia has unanimously determined that the Merger Agreement and the transactions contemplated thereby, including the Merger, are in the best interests of Columbia and Columbia's stockholders and declared the Merger Agreement advisable, and has resolved to recommend that Columbia's stockholders approve the Merger Agreement and submit the Merger Agreement to Columbia's stockholders for approval; and

WHEREAS, the Stockholders are supportive of the Merger Agreement and the transactions contemplated thereby, including the Merger, and have determined that it is in their best interests to enter into this Agreement to provide for their collective support for the Merger Agreement and such transactions, and this Agreement is further a condition and inducement for Northfield to enter into the Merger Agreement.

NOW THEREFORE, in consideration of the foregoing, the mutual covenants and agreements set forth herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, intending to be legally bound, the parties hereto agree as follows:

18.  **<u>Definitions</u>.** Capitalized terms not defined in this Agreement have the meanings assigned
to those terms in the Merger Agreement.

19.  **<u>Effectiveness; Termination</u>.** This Agreement shall be effective
upon signing. This Agreement shall automatically terminate and be null and void and of no effect upon the earliest to occur of
the following: (a) termination of the Merger Agreement for any reason in accordance with its terms, (b) the mutual written agreement
of the parties hereto to terminate this Agreement or (c) the Effective Time; <u>provided</u> that (i) <u>Sections 11</u> through <u>17</u> hereof shall survive any such termination and (ii) such termination shall not relieve any party of any liability or damages
resulting from any willful or material breach of any of its representations, warranties, covenants or other agreements set forth herein.

20.  **<u>Support Agreement</u>.** From the date hereof until the earlier
of (a) the Closing or (b) the termination of the Merger Agreement in accordance with its terms (the " <u>Support Period</u> "),
each Stockholder irrevocably and unconditionally hereby agrees that at any meeting (whether annual or special and each postponement, recess,
adjournment or continuation thereof) of Columbia's stockholders, however called, and in connection with any written consent of Columbia's
stockholders, each Stockholder shall (i) appear at such meeting or otherwise cause all of such Stockholder's Existing Shares
and all other shares of Common Stock or voting securities over which such Stockholder has acquired, after the date hereof, beneficial
or record ownership and the sole power to vote or direct the voting thereof and sole dispositive authority (including any such shares
of Common Stock acquired by means of purchase, dividend or distribution, or issued upon the exercise of any stock options to acquire Common
Stock or the conversion of any convertible securities, or pursuant to any other equity awards or derivative securities (including any
Columbia Equity Awards) or otherwise) (together with the Existing Shares, the " <u>Shares</u> "), as of the applicable record
date, to be counted as present thereat for purposes of calculating a quorum, and (ii) vote or cause to be voted (including by proxy
or written consent, if applicable) all such Shares (A) in favor of the approval of the Merger Agreement and the Plan of Conversion
and the transactions contemplated thereby, (B) in favor of any proposal to adjourn or postpone such meeting of Columbia's stockholders
to a later date if there are not sufficient votes to approve the Merger Agreement and, (C) against any Acquisition Proposal (other
than the transactions contemplated by the Merger Agreement), and (D) against any action, proposal, transaction, agreement or amendment
of the Columbia Articles or Columbia Bylaws, in each case of this clause (D), which would reasonably be expected to (1) result in
a breach of any covenant, representation or warranty or any other obligation or agreement of Columbia contained in the Merger Agreement,
or of a Stockholder contained in this Agreement or (2) prevent, impede, delay, interfere with, postpone, discourage or frustrate
the purposes of or adversely affect the consummation of the transactions contemplated by the Merger Agreement. Each Stockholder agrees
to exercise all voting or other determination rights such Stockholder has in any trust or other legal entity to carry out the intent and
purposes of such Stockholder's obligations in this paragraph and otherwise set forth in this Agreement. Each Stockholder represents,
covenants and agrees that, except for this Agreement, such Stockholder (x) has not entered into, and shall not enter into during
the Support Period, any support or voting agreement or voting trust or similar agreement with respect to the Shares that would be inconsistent
with such Stockholder's obligations under this Agreement and (y) has not granted, and shall not grant during the Support Period,
a proxy, consent or power of attorney with respect to the Shares except any proxy to carry out the intent of and such Stockholder's
obligations under this Agreement and any revocable proxy granted to officers or directors of Columbia at the request of the Board of Directors
of Columbia in connection with election of directors or other routine matters at any annual or special meeting of the Columbia stockholders.
Each Stockholder represents, covenants and agrees that it has not entered into and will not enter into any agreement or commitment with
any person the effect of which would be inconsistent with or otherwise violate any of the provisions and agreements set forth herein; <u>provided</u> that nothing in this sentence will prohibit any Permitted Transfer (as defined below).

21.  **<u>Transfer Restrictions Prior to the Merger</u>.** Each Stockholder
hereby agrees that such Stockholder will not, from the date hereof until the earlier of (a) the end of the Support Period
or (b) approval of the Merger Agreement and the transactions contemplated by the Merger Agreement by the Requisite Columbia Vote,
directly or indirectly, offer for sale, sell, transfer, assign, give, convey, tender in any tender or exchange offer, pledge, encumber,
hypothecate or dispose of (by merger, by testamentary disposition, by operation of law or otherwise), either voluntarily or involuntarily,
enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership
of, or enter into any contract, option or other arrangement or understanding with respect to the sale, transfer, assignment, conveyance,
hypothecation or other transfer or disposition of, any of the Shares, or any legal or beneficial interest therein, whether or not for
value and whether voluntary or involuntary or by operation of law (any of the foregoing, a " <u>Transfer</u> "); <u>provided</u>,
that each Stockholder may Transfer Shares (i) to any of its affiliates, as such term is defined in the Merger Agreement (" <u>Affiliates</u> "),
(ii) to any other person to whom Northfield has consented with respect to a Transfer by such Stockholder in advance in writing, (iii) to
(A) any Family Member (as defined below) of such Stockholder or to a trust solely for the benefit of such Stockholder and/or any
Family Member of such Stockholder or (B) upon the death of such Stockholder pursuant to the terms of any trust or will of such Stockholder

long as the transferee, prior to the date of Transfer, agrees in a signed writing to be bound by and comply with the provisions of this
Agreement with respect to such Transferred Shares, and such Stockholder provides at least three (3) Business Days' prior written
notice (which shall include the written consent of the transferee agreeing to be bound by and comply with the provisions of this Agreement)

any existing stock sale plan adopted in accordance with Rule 10b5-1(c) (Rule 10b5-1) under the Securities Exchange Act
of 1934 for the sale of shares of Common Stock, (v) to any charitable organization that is tax exempt under Section 501(c)(3) of
the Code and (vi) to satisfy any Tax liability incurred by such Stockholder in respect of vesting, exercise or settlement of Columbia
Equity Awards held by Stockholder (any Transfer in accordance with this <u>Section 4</u>, a " <u>Permitted Transfer</u> ").
In the event of any Transfer that would qualify as a Permitted Transfer under more than one of clauses (i) through (vi), the Stockholder
effecting such Transfer may elect the clause to which such Transfer is subject for purposes of complying with this Agreement. As used
in this Agreement, the term " <u>Family Member</u> " means, with respect to each Stockholder: (I) such Stockholder and
Stockholder's spouse, individually, (II) any descendant, niece or nephew of such Stockholder or such Stockholder's spouse,
(III) any charitable organization created and primarily funded by any one or more individuals described in the foregoing (I) or
(II), (IV) any estate, trust, guardianship, custodianship or other fiduciary arrangement for the primary benefit of any one or more

Stockholder in accordance with its terms, and no other action is necessary to authorize the execution and delivery of this Agreement by
such Stockholder or the performance of such Stockholder's obligations hereunder; (c) the execution and delivery of this Agreement
by such Stockholder does not, and the consummation of the transactions contemplated hereby and the compliance with the provisions hereof
will not, conflict with or violate any law or result in any breach of or violation of, or constitute a default (or an event that with
notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or
cancellation of, or result in the creation of a Lien on any of the Shares pursuant to, any agreement or other instrument or obligation
binding upon such Stockholder or the Shares, nor require any authorization, consent or approval of, or filing with, any Governmental Entity
(other than an amendment to such Stockholder's Schedule 13D filed with the Securities and Exchange Commission, if any); (d) such
Stockholder beneficially owns and has the sole power to vote or direct the voting of the Shares, including all of such Stockholder's
Existing Shares as set forth on, and in the amounts set forth on,  **<u>Schedule A</u>** hereto, which as of the date hereof constitute
all of the shares of Common Stock beneficially owned by such Stockholder and over which such Stockholder, directly or indirectly, has
sole voting and dispositive authority; (e) such Stockholder beneficially owns such Stockholder's Existing Shares as set forth
on Schedule A hereto free and clear of any proxy, voting restriction, adverse claim or other Lien (other than any restrictions created

the Securities and Exchange Commission, if any); and (f) such Stockholder has read and is familiar with the terms of the Merger Agreement

As used in this Agreement, the terms " <u>beneficial owner</u>," " <u>beneficially own</u> " and " <u>beneficial ownership</u> " shall have the meaning set forth

in any announcement or disclosure in connection with the Merger, including in the S-4, the Joint Proxy Statement/Prospectus or any other
filing with any Governmental Entity made in connection with the Merger, such Stockholder's identity and ownership of such Stockholder's
Shares and the nature of such Stockholder's obligations under this Agreement.

or implied, is intended to or shall confer upon any person not a party to this Agreement any right, benefit or remedy of any nature whatsoever

to each Stockholder, subject to the agreements of the parties set forth herein. This Agreement is intended to create, and creates, a contractual

NOW THEREFORE, in consideration of the foregoing, the mutual covenants and agreements set forth herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, intending to be legally bound, the parties hereto agree as follows:

1.  **<u>Definitions</u>.** Capitalized terms not defined in this Agreement have the meanings assigned

the purposes of or adversely affect the consummation of the transactions contemplated by the Merger Agreement. Each Stockholder agrees

by such Stockholder does not, and the consummation of the transactions contemplated hereby and the compliance with the provisions hereof
will not, conflict with or violate any law or result in any breach of or violation of, or constitute a default (or an event that with
notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or
cancellation of, or result in the creation of a Lien on any of the Shares pursuant to, any agreement or other instrument or obligation
binding upon such Stockholder or the Shares, nor require any authorization, consent or approval of, or filing with, any Governmental Entity
(other than an amendment to such Stockholder's Schedule 13D filed with the Securities and Exchange Commission, if any); (d) such
Stockholder beneficially owns and has the sole power to vote or direct the voting of the Shares, including all of such Stockholder's
Existing Shares as set forth on, and in the amounts set forth on,  **<u>Schedule A</u>** hereto, which as of the date hereof constitute
all of the shares of Common Stock beneficially owned by such Stockholder and over which such Stockholder, directly or indirectly, has
sole voting and dispositive authority; (e) such Stockholder beneficially owns such Stockholder's Existing Shares as set forth

Shares and the nature of such Stockholder's obligations under this Agreement.

or for which any or all of such shares may be changed or exchanged or which are received in such transaction.

8.  **<u>Entire Agreement</u>.** This Agreement and, to the extent referenced herein, the Merger Agreement
constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all other prior agreements and

or implied, is intended to or shall confer upon any person not a party to this Agreement any right, benefit or remedy of any nature whatsoever
under or by reason of this Agreement. Nothing in this Agreement shall, or shall be construed or deemed to, constitute a Transfer
of any Shares or any legal or beneficial interest in or voting or other control over any of the Shares or as creating or forming a "group"

to each Stockholder, subject to the agreements of the parties set forth herein. This Agreement is intended to create, and creates, a contractual
relationship and is not intended to create, and does not create, any agency, partnership, joint venture or other like relationship between

intended to be legally binding and specifically enforceable pursuant to its terms and that each party would be irreparably harmed if any
of the provisions of this Agreement are not performed in accordance with their specific terms and that monetary damages would not provide
an adequate remedy in such event. Accordingly, in the event of any breach or threatened breach by any party of any provision contained
in this Agreement, in addition to any other remedy to which the other parties may be entitled whether at law or in equity (including monetary
damages), each other party shall be entitled to injunctive relief to prevent breaches or threatened breaches of this Agreement and to
specifically enforce the terms and provisions hereof, and each party hereby waives any defense in any action for specific performance
or an injunction or other equitable relief that a remedy at law would be adequate. Each party further agrees that no party shall
be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred
to in this paragraph, and each party irrevocably waives any right such party may have to require the obtaining, furnishing or posting
of any such bond or similar instrument.

## Exhibit 99.1

**Exhibit 99.1**

**COLUMBIA FINANCIAL, INC.**

**AND NORTHFIELD BANCORP, INC.**

**ANNOUNCE PLANS TO MERGE**

***Columbia to Undertake Second-Step Conversion in Connection with Transaction***

**Fair Lawn, New Jersey and Woodbridge, New Jersey** (February 2, 2026): Columbia Financial, Inc. ("Columbia") (NASDAQ: CLBK), the mid-tier holding company for Columbia Bank (the "Bank"), and Northfield Bancorp, Inc. ("Northfield") (NASDAQ: NFBK), the holding company for Northfield Bank, jointly announced today that they have entered into an agreement and plan of merger for Columbia to acquire Northfield in a transaction valued at approximately $597 million. The combination of the two organizations will create the third largest regional bank headquartered in New Jersey, with pro forma total assets of $18 billion based on financial data as of December 31, 2025.

In connection with the announcement of the merger, Columbia also announced that its Board of Directors, together with the Boards of Directors of Columbia Bank MHC (the "MHC") and the Bank, have unanimously adopted a plan of conversion and reorganization, pursuant to which (i) shares representing the majority ownership of the MHC will be sold to the public at a price of $10.00 per share and (ii) the Bank, which is currently in the mutual holding company structure, will reorganize into the fully public stock holding company form of organization in a transaction commonly referred to as a "second-step" conversion. As part of the second-step conversion, the Bank will become a wholly owned subsidiary of a new holding company formed in connection with the transaction (the "Holding Company").

Under the plan of conversion and reorganization, shares of common stock of Columbia held by persons other than the MHC, which currently represent approximately 26.9% of Columbia's outstanding common shares, will be converted into shares of common stock of the newly formed Holding Company pursuant to an exchange ratio intended to preserve the percentage ownership interests of such persons. Shares of common stock of Columbia held by the MHC, which currently represent approximately 73.1% of Columbia's outstanding common shares, will be cancelled in connection with the transaction. In the conversion stock offering, depositors of Columbia Bank with qualifying deposits as of December 31, 2024 will have first priority non-transferable subscription rights to subscribe for shares of common stock of the Holding Company. The number of shares of common stock of the Holding Company to be issued in the proposed stock offering will be based on the aggregate pro forma market value of the common stock of the Holding Company, after giving effect to the proposed merger with Northfield, as determined by an independent appraisal (the "Independent Valuation").

Under the terms of the merger agreement, Northfield will merge into the Holding Company immediately following the completion of the second-step conversion. At the effective time of the merger, each outstanding share of Northfield common stock will be converted into the right to receive either shares of Holding Company common stock or cash, without interest, at the election of the holder, as follows: (i) if the final Independent Valuation is less than $2.3 billion, either 1.425 shares of Holding Company common stock or $14.25 in cash; (ii) if the Independent Valuation is equal to or greater than $2.3 billion and less than $2.6 billion, either 1.450 shares of Holding Company common stock or $14.50 in cash, or (iii) if the Independent Valuation is equal to or greater than $2.6 billion, 1.465 shares of Holding Company common stock or $14.65 in cash. Under the terms of the merger agreement, no more than 30% of the outstanding shares of Northfield common stock issued and outstanding as of the effective time of the merger may be converted into the cash consideration. The merger will only occur if the second-step conversion is completed.

On a pro forma basis at the midpoint of the estimated valuation range for the second-step conversion based on a preliminary independent appraisal, Columbia anticipates that the merger with Northfield would be 50% accretive to Columbia's 2027 earnings per share.

Following the completion of the merger, Thomas J. Kemly will continue to serve as President and Chief Executive Officer of the Holding Company and the Bank, Dennis E. Gibney will continue to serve as First Senior Executive Vice President and Chief Banking Officer of the Holding Company and Columbia Bank and Thomas F. Splaine, Jr. will continue to serve as Executive Vice President and Chief Financial Officer of the Holding Company and Columbia Bank.

In addition, at the effective time of the merger, Steven M. Klein, Chairman, President and Chief Executive Officer of Northfield, will become Senior Executive Vice President and Chief Operating Officer of the Holding Company and Columbia Bank. Following the completion of the merger, the Board of Directors of the Holding Company and Columbia Bank will consist of the directors of Columbia and Columbia Bank as of the effective time of the merger, as well as four members of Northfield's board of directors, including Steven M. Klein.

"We are excited to announce our second-step conversion and simultaneous merger with Northfield. The simultaneous merger allows us to immediately leverage a portion of the capital raised and materially augment financial results," said Thomas J. Kemly, President and Chief Executive Officer of Columbia. "Northfield has built an excellent deposit franchise with a conservative credit culture, which makes it an ideal fit with Columbia and provides great opportunities for future growth."

"Founded in 1887, in the Northfield section of Staten Island, Northfield Bank has been serving its communities for nearly 140 years. Guided by its core values of Trust, Respect, and Excellence, our team members make a positive difference in the lives and businesses of those in our communities every day." said Steven M. Klein, Chairman, President and Chief Executive Officer of Northfield. "I have known and respected the Columbia team for nearly 40 years, and I believe this combination will create enormous value and opportunity for our team members, customers, and stockholders."

The merger agreement has been unanimously approved by the Boards of Directors of both Columbia and Northfield. The completion of the merger is subject to the satisfaction of various closing conditions, including the completion of the second-step conversion, the receipt of all required regulatory approvals and the approval of the merger by the stockholders of both Columbia and Northfield. The completion of the second-step conversion is also subject to the satisfaction of various closing conditions, including the receipt of all required regulatory approvals, the approval of the conversion by the depositors and certain borrowers of Columbia Bank and the approval of the conversion by the stockholders of Columbia.

The second-step conversion, the conversion offering and the merger are expected to be completed early in the third quarter of 2026.

Keefe, Bruyette & Woods, Inc., *A Stifel Company*, is serving as financial advisor to Columbia. Keefe Bruyette & Woods, Inc., *A Stifel Company*, will also act as marketing agent for the subscription and community offerings and the lead left book-running manager for any firm commitment underwritten offering conducted by the Holding Company in connection with the second-step conversion. Raymond James & Associates, Inc. is serving as financial advisor to Northfield, and has rendered a fairness opinion to the Board of Directors of Northfield.

Kilpatrick Townsend & Stockton LLP is serving as legal counsel to Columbia and Luse Gorman, PC is serving as legal counsel to Northfield.

Such risks, uncertainties and assumptions, include, among others, the following: (i) the occurrence of any event, change or other circumstances that could give rise to the right of one or both of the parties to terminate the merger agreement; (ii) the failure to obtain necessary regulatory approvals (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the proposed transaction) and the possibility that the proposed transaction does not close when expected or at all because required regulatory approvals, the approval by Columbia's and/or Northfield's stockholders, or other approvals and the other conditions to closing are not received or satisfied on a timely basis or at all; (iii) the outcome of any legal proceedings that may be instituted against Columbia or Northfield; (iv) the possibility that the anticipated benefits of the proposed transaction, including anticipated cost savings and strategic gains, are not realized when expected or at all, including as a result of changes in, or problems arising from, general economic and market conditions, interest and exchange rates, monetary policy, laws and regulations and their enforcement, and the degree of competition in the geographic and business areas in which Columbia and Northfield operate; (v) the possibility that the integration of the two companies may be more difficult, time-consuming or costly than expected; (vi) Columbia's ability to successfully complete its second step conversion; (vi) the possibility that the final independent appraisal of Columbia will differ from the preliminary independent appraisal of Columbia; (viii) the impact of purchase accounting with respect to the proposed transaction, or any change in the assumptions used regarding the assets acquired and liabilities assumed to determine their fair value and credit marks; (ix) the possibility that the proposed transaction may be more expensive or take longer to complete than anticipated, including as a result of unexpected factors or events; (x) the diversion of management's attention from ongoing business operations and opportunities; (xi) potential adverse reactions of Columbia's or Northfield's customers or changes to business or employee relationships, including those resulting from the announcement or completion of the proposed transaction; (xii) a material adverse change in the financial condition of Columbia or Northfield; (xiii) changes in Columbia's or Northfield's share price before closing; (xiv) risks relating to the potential dilutive effect of shares of Columbia's common stock to be issued in the proposed transaction; (xv) general competitive, economic, political and market conditions, including the impact of any potential government shutdown; (xvi) major catastrophes such as earthquakes, floods or other natural or human disasters, including infectious disease outbreaks; and (xvii) other factors that may affect future results of Columbia or Northfield, including, among others, changes in asset quality and credit risk; the imposition of tariffs and any retaliatory responses; the inability to sustain revenue and earnings growth; changes in interest rates; deposit flows; inflation; customer borrowing, repayment, investment and deposit practices; the impact, extent and timing of technological changes; capital management activities; and other actions of the Federal Reserve Board and legislative and regulatory actions and reforms.

These factors are not necessarily all of the factors that could cause Columbia's, Northfield's or the combined company's actual results, performance or achievements to differ materially from those expressed in or implied by any of the forward-looking statements. Other factors, including unknown or unpredictable factors, also could harm Columbia's, Northfield's or the combined company's results.

Although each of Columbia and Northfield believes that its expectations with respect to forward-looking statements are based upon reasonable assumptions based on its existing knowledge of its business and operations, there can be no assurance that actual results of Columbia or Northfield will not differ materially from any projected future results expressed or implied by such forward-looking statements. Additional factors that could cause results to differ materially from those described above can be found in Columbia's most recent annual report on Form 10-K for the fiscal year ended December 31, 2024, quarterly reports on Form 10-Q, and other documents subsequently filed by Columbia with the Securities Exchange Commission (the "SEC"), and in Northfield's most recent annual report on Form 10-K for the fiscal year ended December 31, 2024, and its other filings with the SEC and quarterly reports on Form 10-Q, and other documents subsequently filed by Northfield with the SEC. The actual results anticipated may not be realized or, even if substantially realized, they may not have the expected consequences to or effects on Columbia, Northfield or each of their respective businesses or operations. Investors are cautioned not to rely too heavily on any such forward-looking statements. Columbia and Northfield urge you to consider all of these risks, uncertainties and other factors carefully in evaluating all such forward-looking statements made by Columbia and Northfield. Forward-looking statements speak only as of the date they are made and Columbia and/or Northfield undertake no obligation to update or clarify these forward-looking statements, whether as a result of new information, future events or otherwise, except to the extent required by applicable law.

4 Non - GAAP Financial Measures This presentation contains financial information presented in accordance with U.S. Generally Accepted Accounting Principles ("GA AP"). This presentation also contains certain non - GAAP information that the Company's management uses in its analysis of the Company's financial results, including tangible stockholders' equit y t o tangible assets ("TCE / TA") and other non - GAAP metrics. Specifically, the Company provides measures based on what it believes are its operating earnings on a consistent basis and excludes materia l n on - routine operating items which affect the GAAP reporting of results of operations. The Company's management believes that providing this information to analysts and investors allows them to bet ter understand and evaluate the Company's core financial results for the periods presented. Because non - GAAP financial measures are not standardized, it may not be possible to compare these financial m easures with other companies' non - GAAP financial measures having the same or similar names. The Company also provides measurements and ratios based on tangible stockholders' equity. T hes e measures are commonly utilized by regulators and market analysts to evaluate the Company's financial condition and, therefore, the Company's management believes that such informatio n i s useful to investors. A reconciliation of the non - GAAP financial measures used in this presentation to the most directly comparable GAAP measures is provided in the appendix to this presenta tio n. Pro Forma Forward - Looking Data Neither Columbia's nor Northfield's independent registered public accounting firms have studied, reviewed or performed any pr oce dures with respect to the pro forma forward - looking financial data for the purpose of inclusion in this presentation, and, accordingly, neither have expressed an opinion or provided any form of as sur ance with respect thereto for the purpose of this presentation. This pro forma forward - looking financial data is for illustrative purposes only and should not be relied on as necessarily being indicati ve of future results. The assumptions and estimates underlying the proforma forward - looking financial data are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information, including those in the "Disclaimer and Caution abou t F orward - Looking Statements" disclaimer on slide 2 of this presentation. Pro forma forward - looking financial data is inherently uncertain due to a number of factors outside of Columbia's and Northfield's c ontrol. Accordingly, there can be no assurance that the prospective results are indicative of future performance of the combined company after the proposed second step conversion and acquisition or tha t a ctual results will not differ materially from those presented in the pro forma forward - looking financial data. Inclusion of pro forma financial data in this presentation should not be regarded as a rep resentation by any person that the results contained in the prospective financial information will be achieved.
