MERGER PROPOSAL
YOUR VOTE IS IMPORTANT

Dear Fellow Shareholder:

On December 20, 2019, the board of directors of VSB Bancorp, Inc. (which we refer to as “VSB Bancorp”) unanimously adopted a merger agreement between VSB Bancorp and Northfield Bancorp, Inc. (which we refer to as “Northfield Bancorp”). VSB Bancorp is holding a special meeting of its shareholders to vote on the merger between VSB Bancorp and Northfield Bancorp. If the merger agreement is adopted and the merger is subsequently completed, VSB Bancorp will merge with and into Northfield Bancorp, VSB Bancorp’s separate corporate existence will cease and Northfield Bancorp will continue as the surviving corporation.

Under the terms of the merger agreement, each outstanding share of VSB Bancorp common stock will be converted into the right between 1.8514 shares of Northfield Bancorp common stock and 2.0463 shares of Northfield Bancorp common stock, as determined by dividing (rounded to the fourth decimal place) $33.30 by Northfield Bancorp’s average stock price for a ten-day period ending on the fifth business day prior to the closing of the merger. However, if the average stock price is greater than $17.99, then the exchange ratio will be 1.8514, and if the average stock price is less than $16.27, then the exchange ratio will be 2.0463. Based on an average price of $17.13, which was the ten-day average closing stock price of Northfield Bancorp common stock as of December 20, 2019, which was the last trading date preceding the public announcement of the proposed merger, the merger consideration would have been 1.9440 shares of Northfield Bancorp common stock for each share of VSB Bancorp common stock. As of , the most reasonably practicable date before the mailing of this Proxy Statement/Prospectus, the 10-day average closing stock price of Northfield Bancorp common stock was $ , resulting in merger consideration of shares of Northfield Bancorp common stock for each share of VSB Bancorp common stock.

The common stock of Northfield Bancorp trades on the Nasdaq Global Select Market under the symbol “NFBK.” The common stock of VSB Bancorp trades on the OTCQX Best Market under the symbol “VSBN.” The market price of both Northfield Bancorp common stock and VSB Bancorp common stock will fluctuate before the completion of the merger. Therefore, we urge you to obtain current market quotations for Northfield Bancorp common stock and VSB Bancorp common stock before you decide how to vote on the merger proposal.

The maximum number of shares of Northfield Bancorp common stock estimated to be issuable upon completion of the merger is . Following the completion of the merger, former VSB Bancorp shareholders will hold approximately % of Northfield Bancorp’s common stock.

VSB Bancorp has the right to terminate the merger agreement if the average closing price of Northfield Bancorp common stock calculated to determine the merger consideration prior to the closing (1) is less than $14.56 and (2) decreases by more than 15% relative to the SNL Small Cap U.S. Bank and Thrift Index since the date of the merger agreement. If VSB Bancorp elects to exercise this termination right, then Northfield Bancorp has the option to override the proposed termination by increasing the exchange ratio to a level that would eliminate the effects of either of the two requirements of this termination right.

Your board of directors has unanimously determined that the merger agreement and the merger are in the best interests of VSB Bancorp and its shareholders and unanimously recommends that you vote “FOR” adoption of the merger agreement and the merger. The merger cannot be completed unless holders of a majority of the issued and outstanding shares of common stock of VSB Bancorp vote to adopt the merger agreement and the merger. Whether or not you plan to attend the special meeting of shareholders, please vote by completing the enclosed proxy card and mailing it in the enclosed envelope. If you sign, date and mail your proxy card without indicating how you want to vote, your proxy will be counted “FOR” adoption of the merger agreement and the merger and “FOR” the proposal to adjourn the special meeting if necessary or appropriate to solicit additional proxies if there are not sufficient votes to adopt the merger agreement and the merger. You may also vote by telephone or Internet as indicated on the proxy card. If you fail to vote, or you do not instruct your broker how to vote any shares held for you in “street name,” it will have the same effect as voting “AGAINST” the merger agreement and the merger, but it will have no effect on the proposal to adjourn the special meeting.

This document, which we refer to as the Proxy Statement/Prospectus, is being delivered to VSB Bancorp shareholders as Northfield Bancorp’s prospectus for its offering of common stock in connection with the merger, and as a proxy statement for the solicitation of proxies from VSB Bancorp shareholders to vote for the adoption of the merger agreement and the merger.

The Proxy Statement/Prospectus provides you with detailed information about the proposed merger. It also contains or references information about Northfield Bancorp and VSB Bancorp and related matters. You are encouraged to read this document carefully. In particular, you should read the “Risk Factors” section beginning on page for a discussion of the risks you should consider in evaluating the proposed merger and how it will affect you.

VSB Bancorp shareholders are entitled to exercise dissenters’ rights with respect to the merger under Section 910 of the New York Business Corporation Law (which we refer to as the “NYBCL”). Any VSB Bancorp shareholder who wishes to exercise dissenters’ rights must strictly comply with the procedures set forth in Sections 623 and 910 of the NYBCL, a copy of which is included as Appendix C to the Proxy Statement/Prospectus. A description of these procedures is included in the section of the Proxy Statement/Prospectus entitled “Dissenters’ Rights.”

Your vote is important and I urge you to cast it promptly.

| Sincerely,
| Raffaele M. Branca
| President and Chief Executive Officer

QUESTIONS AND ANSWERS ABOUT THE MERGER AND THE SPECIAL MEETING

The following are answers to certain questions that you may have regarding the Merger and the special meeting. We urge you to read carefully the remainder of this Proxy Statement/Prospectus because the information in this section may not provide all the information that might be important to you in determining how to vote. Additional important information is also contained in the appendices to, and the documents incorporated by reference in, this Proxy Statement/Prospectus.

GENERAL QUESTIONS ABOUT THE MERGER

| Q: | WHY AM I RECEIVING THIS DOCUMENT?

| A: | We are sending this document to you because our records show that you are an owner of record of VSB Bancorp, Inc. (which we refer to as “VSB Bancorp”) common stock, or a bank, broker or other nominee acting for you owns common stock of VSB Bancorp. Northfield Bancorp, Inc. (which we refer to as “Northfield Bancorp”) and VSB Bancorp have agreed to merge under the terms of an Agreement and Plan of Merger by and between Northfield Bancorp and VSB Bancorp, dated as of December 23, 2019 (which we refer to as the “Merger Agreement”), that is described in this Proxy Statement/Prospectus. A copy of the Merger Agreement is attached to this Proxy Statement/Prospectus as Appendix A. In order to complete the merger of VSB Bancorp into Northfield Bancorp (the “Merger”), the shareholders of VSB Bancorp must vote to adopt the Merger Agreement and the Merger. VSB Bancorp will hold a special meeting of its shareholders to obtain this approval. This Proxy Statement/Prospectus contains important information about the Merger, the Merger Agreement, the special meeting and other related matters, and you should read it carefully.

| Q: | WHO IS BEING ASKED TO ADOPT THE MERGER AGREEMENT AND THE MERGER?

| A: | VSB Bancorp shareholders as of [record date] are being asked to vote to adopt the Merger Agreement and Merger.

Under New York law, which governs the Merger, the Merger cannot be completed unless VSB Bancorp shareholders vote to adopt the Merger Agreement. By this Proxy Statement/Prospectus, VSB Bancorp’s board of directors is soliciting proxies from VSB Bancorp’s shareholders to obtain this approval at the special meeting of VSB Bancorp shareholders discussed below.

| Q: | WHAT WILL VSB BANCORP SHAREHOLDERS RECEIVE IN THE MERGER?

| A: | If the Merger proposal is approved and the Merger is subsequently completed, each outstanding share of VSB Bancorp common stock will be converted into the right to receive between 1.8514 shares of Northfield Bancorp common stock and 2.0463 shares of Northfield Bancorp common stock, as determined by dividing (rounded to the fourth decimal place) $33.30 by Northfield Bancorp’s average stock price for the ten-day period ending on the fifth business day prior to the closing of the Merger. However, if the average stock price is greater than $17.99, then the exchange ratio will be 1.8514, and if the average stock price is less than $16.27, then the exchange ratio will be 2.0463.

Based on an average price of $17.13, which was the ten-day average closing stock price of Northfield Bancorp common stock as of December 20, 2019, which was the last trading date preceding the public announcement of the proposed Merger, the merger consideration would have been 1.9440 shares of Northfield Bancorp common stock for each share of VSB Bancorp common stock. As of , the most reasonably practicable date before the mailing of this Proxy Statement/Prospectus, the ten-day average closing stock price of Northfield Bancorp common stock was $ , resulting in merger consideration of shares of Northfield Bancorp common stock for each share of VSB Bancorp common stock.

For more information, see “Proposal 1—The Merger Proposal—Consideration to be Received in the Merger.”

| Q: | ARE VSB BANCORP SHAREHOLDERS ENTITLED TO DISSENTERS’ RIGHTS?

| A: | Yes. VSB Bancorp shareholders are entitled to exercise dissenters’ rights in connection with the Merger, which means that a dissenting shareholder is entitled to receive the fair value of his, her or its shares in cash (which may be more or less than the value of the merger consideration that such holder would receive in the Merger), if the dissenting shareholder does not vote in favor of the Merger, complies with the requirements set forth in

1

TABLE OF CONTENTS

Sections 623 and 910 of the New York Business Corporation Law (which we refer to as the “NYBCL”) and the Merger is completed. You should read carefully the detailed description of the requirements to exercise dissenters’ rights in “Dissenters’ Rights” beginning on page , as well as the full text of Sections 623 and 910 of the NYBCL, which are attached to this Proxy Statement/Prospectus as Appendix C.

It is a condition to Northfield Bancorp’s obligation to complete the Merger that the holders of not more than 10% of the outstanding shares of VSB Bancorp common stock exercise dissenters’ rights.

| Q: | WHAT ARE THE MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER TO VSB BANCORP SHAREHOLDERS?

| A: | Northfield Bancorp and VSB Bancorp have each received a legal opinion that the Merger will qualify as a tax-free reorganization within the meaning of Section 368(a) of the Internal Revenue Code. If you are a United States holder of VSB Bancorp common stock, generally you should not recognize a gain or loss with respect to the exchange of shares of VSB Bancorp common stock for shares of Northfield Bancorp common stock in the Merger except with respect to cash received in lieu of a fractional share of Northfield Bancorp common stock. However, VSB Bancorp shareholders generally will recognize gain or loss with respect to cash received in lieu of fractional shares of Northfield Bancorp common stock that the VSB Bancorp shareholders would otherwise be entitled to receive.

For a more detailed discussion of the material United States federal income tax consequences of the transaction, please see the section “Proposal 1—The Merger Proposal—Material U.S. Federal Income Tax Consequences of the Merger” beginning on page .

The tax consequences of the Merger to any particular shareholder will depend on that shareholder’s particular facts and circumstances. Accordingly, we urge you to consult your tax advisor to determine the tax consequences of the Merger to you.

| Q: | WHAT WILL HAPPEN TO VSB BANCORP AS A RESULT OF THE MERGER?

| A: | If the Merger is completed, VSB Bancorp will merge into Northfield Bancorp, and VSB Bancorp will cease to exist. Following the Merger, Victory State Bank, a New York bank and wholly-owned subsidiary of VSB Bancorp, will merge with and into Northfield Bank, a federally chartered savings bank and wholly-owned subsidiary of Northfield Bancorp, with Northfield Bank being the surviving bank.

| Q: | WHEN WILL THE MERGER BE COMPLETED?

| A: | The Merger will be completed when all of the conditions to completion contained in the Merger Agreement are satisfied or waived, including the receipt of required regulatory approvals and the favorable vote of VSB Bancorp shareholders at the VSB Bancorp special meeting. We currently expect to complete the Merger during the second quarter of 2020. However, because fulfillment of some of the conditions to completion of the Merger, such as the receipt of required regulatory approvals, is not entirely within our control, we cannot predict the actual timing.

| Q: | WHAT HAPPENS IF THE MERGER IS NOT COMPLETED?

| A: | If the Merger is not completed, VSB Bancorp shareholders will not receive any consideration for their shares of common stock in connection with the Merger. Instead, VSB Bancorp will remain an independent company and we anticipate that its common stock will continue to be quoted and traded on the OTCQX Best Market. Under specified circumstances, VSB Bancorp may be required to pay to Northfield Bancorp a fee with respect to the termination of the Merger Agreement. For more information, please review the sections entitled “Proposal 1—The Merger Proposal—Terminating the Merger Agreement” beginning on page and “—Termination Fee” beginning on page .

| Q: | WHERE CAN I FIND MORE INFORMATION ABOUT NORTHFIELD BANCORP?

| A: | You can find more information about Northfield Bancorp from the various sources described under the section entitled “Where You Can Find More Information” at the end of this Proxy Statement/Prospectus.

| Q: | WHO CAN VOTE AT THE SPECIAL MEETING?

| A: | Holders of record of VSB Bancorp common stock at the close of business on [record date], which is the record date for the special meeting, are entitled to vote at the special meeting. If you are a beneficial owner of shares of VSB Bancorp common stock held by a broker, bank or other nominee (i.e., in “street name”) and you want to vote your shares in person at the meeting, you will have to get a written proxy in your name from the broker, bank or other nominee who holds your shares.

| Q: | HOW MANY VOTES MUST BE REPRESENTED IN PERSON OR BY PROXY AT THE VSB BANCORP SPECIAL MEETING TO HAVE A QUORUM?

| A: | The holders of at least shares of VSB Bancorp common stock, being one-third (331∕3%) of the shares of VSB Bancorp common stock entitled to vote at the special meeting will constitute a quorum at the special meeting.

| Q: | WHAT MATTERS ARE VSB BANCORP SHAREHOLDERS BEING ASKED TO APPROVE AT THE VSB BANCORP SPECIAL MEETING PURSUANT TO THIS PROXY STATEMENT/PROSPECTUS?

| A: | VSB Bancorp shareholders are being asked to adopt the Merger Agreement and the Merger. We refer to this proposal as the “Merger Proposal.”

VSB Bancorp shareholders are also being asked to approve one or more adjournments of the special meeting, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes at the time of the special meeting to approve the Merger Proposal, which we refer to as the “Adjournment Proposal.”

| Q: | WHAT VOTE BY VSB BANCORP SHAREHOLDERS IS REQUIRED TO APPROVE THE PROPOSALS?

| A: | Adoption of the Merger Proposal will require the affirmative vote of the holders of a majority of the shares of VSB Bancorp common stock entitled to vote at the special meeting. Abstentions and broker non-votes will have the same effect as voting against the Merger Proposal.

Approval of the Adjournment Proposal will require the affirmative vote of a majority of the votes cast at the special meeting. Abstentions and broker non-votes will not affect whether the proposal is approved.

As of the record date for the special meeting, directors and executive officers of VSB Bancorp, together with their affiliates have voting power over approximately [insider ownership]% of the outstanding VSB Bancorp common stock. Each of these directors and executive officers of VSB Bancorp, who own in the aggregate [insider shares] shares of common stock of VSB Bancorp, or % of the outstanding shares, have entered into voting agreements with Northfield Bancorp to vote the shares of VSB Bancorp common stock over which they have voting control, or % of the outstanding share, “FOR” the Merger Proposal.

| Q: | HOW MAY VSB BANCORP SHAREHOLDERS VOTE THEIR SHARES FOR THE SPECIAL MEETING PROPOSALS PRESENTED IN THIS PROXY STATEMENT/PROSPECTUS?

| A: | Shareholders who received a proxy card may vote by completing, signing, dating and returning the proxy card in the enclosed prepaid return envelope or proxy card as soon as possible or by attending the special meeting and voting in person. Shareholders may also vote by telephone or Internet as indicated on the proxy card. This will enable your shares to be represented and voted at the special meeting. If your stock is held in street name, do not vote directly by submitting a proxy card to VSB Bancorp. Instead, you will receive

TABLE OF CONTENTS

instructions from your broker, bank or other nominee that you must follow to have your shares voted. Your broker, bank or other nominee may allow you to deliver your voting instructions via the telephone or the Internet. Please review the proxy card or instruction form provided by your broker, bank or other nominee that accompanies this Proxy Statement/Prospectus.

| Q: | WILL A BROKER OR BANK HOLDING SHARES IN “STREET NAME” FOR A VSB BANCORP SHAREHOLDER AUTOMATICALLY VOTE THOSE SHARES FOR THE SHAREHOLDER AT THE VSB BANCORP SPECIAL MEETING?

| A: | No. A broker or bank WILL NOT be able to vote your shares with respect to the Merger Agreement and the Merger without first receiving instructions from you on how to vote. If your shares are held in “street name,” you will receive separate voting instructions with your proxy materials. It is important that you provide timely instruction to your broker or bank to ensure that all shares of VSB Bancorp common stock that you own are voted at the special meeting. The failure of a shareholder whose shares of VSB Bancorp common stock are held in “street name” to give voting instructions to the broker or bank will have the same effect as a vote “AGAINST” the Merger Proposal.

| Q: | WILL VSB BANCORP SHAREHOLDERS BE ABLE TO VOTE THEIR SHARES AT THE SPECIAL MEETING IN PERSON?

| A: | Yes. Submitting a proxy will not affect the right of any shareholder to vote in person at the special meeting. If you hold your shares in “street name” and wish to attend and vote your shares at the special meeting, you will have to get a written proxy in your name from the broker, bank or other nominee who holds your shares.

| Q: | MAY A VSB BANCORP SHAREHOLDER CHANGE OR REVOKE HIS OR HER VOTE AFTER SUBMITTING A PROXY?

| A: | Yes. If you have not voted through your broker, you can change your vote by:

| • | providing written notice of revocation to the Corporate Secretary of VSB Bancorp at any time before the special meeting begins;

What VSB Bancorp, Inc. Shareholders Will Receive in the Merger (page )

Under the Merger Agreement, each share of VSB Bancorp common stock will be converted into the right to receive between 1.8514 shares of Northfield Bancorp common stock and 2.0463 shares of Northfield Bancorp common stock, as determined by dividing (rounded to the fourth decimal place) $33.30 by Northfield Bancorp’s average stock price for a ten-day period ending on the fifth business day prior to the closing of the Merger. However, if the average stock price is greater than $17.99, then the exchange ratio will be 1.8514, and if the average stock price is less than $16.27, then the exchange ratio will be 2.0463.

Based on an average price of $17.13, which was the ten-day average closing stock price of Northfield Bancorp common stock as of December 20, 2019, which was the last trading date preceding the public announcement of the proposed Merger, the merger consideration would have been 1.9440 shares of Northfield Bancorp common stock for each share of VSB Bancorp common stock. As of , the most reasonably practicable date before the mailing of this Proxy Statement/Prospectus, the ten-day average closing stock price of Northfield Bancorp common stock was $ , resulting in merger consideration of shares of Northfield Bancorp common stock for each share of VSB Bancorp common stock.

TABLE OF CONTENTS

Terminating the Merger Agreement (page )

The Merger Agreement may be terminated by mutual consent of Northfield Bancorp and VSB Bancorp at any time before the completion of the Merger. Additionally, subject to conditions and circumstances described in the Merger Agreement, either Northfield Bancorp or VSB Bancorp may terminate the Merger Agreement if, among other things, any of the following occur:

| • | there is a material breach by the other party of any representation, warranty, covenant or agreement contained in the Merger Agreement, which breach cannot be cured before October 31, 2020, or has not been cured within 30 days after the giving of written notice to such party of such breach;

| • | the Merger has not been consummated by October 31, 2020, or such later date as agreed to by the parties, unless the failure to complete the Merger by that time was due to such party’s material breach of any representation, warranty, covenant or other agreement provided in the Merger Agreement;

| • | VSB Bancorp shareholders do not approve the Merger Agreement at the VSB Bancorp special meeting; provided that VSB Bancorp can only terminate under this provision if it satisfied its obligations regarding calling and holding the special meeting of shareholders; or

| • | a required regulatory approval is denied or a court of competent jurisdiction or a governmental authority prohibits the consummation of the Merger.

VSB Bancorp may terminate the Merger Agreement if, as of the fifth business day prior to the closing date (which we refer to as the “Determination Date”), both of the following conditions are satisfied:

| • | the number obtained by dividing the average of the daily closing prices of Northfield Bancorp common stock for the ten consecutive trading days immediately preceding the Determination Date is less than $14.56; and

| • | the number obtained by dividing (1) the average of the daily closing prices of Northfield Bancorp common stock for the ten consecutive trading days immediately preceding the Determination Date by (2) $17.13 is less than the number obtained by dividing (x) the average of the daily closing prices for the ten consecutive trading days immediately preceding the Determination Date of the SNL Small Cap U.S. Bank and Thrift Index (which we refer to as the “Final Index Price”) by (y) the closing value of the SNL Small Cap U.S. Bank and Thrift Index on the last trading date immediately preceding the public announcement of the Merger Agreement (which we refer to as the “Initial Index Price”), minus 0.15 (which we refer to as the “Index Ratio”).

However, if VSB Bancorp chooses to exercise this termination right, Northfield Bancorp has the option, within three business days of receipt of notice from VSB Bancorp, to adjust the merger consideration by increasing the exchange ratio to a level that would not allow VSB Bancorp to terminate under this provision.

VSB Bancorp may also terminate the Merger Agreement if it receives a proposal from a third party that the VSB Bancorp board of directors determines, after consultation with its legal and financial advisors, would provide consideration to VSB Bancorp’s shareholders that is more favorable, from a financial point of view, than the merger consideration being paid by Northfield Bancorp, and is reasonably likely to be completed on the terms proposed.

Northfield Bancorp also may terminate the Merger Agreement if the board of directors of VSB Bancorp does not recommend approval of the Merger Agreement in this Proxy Statement/Prospectus or withdraws, qualifies or modifies its recommendation in a manner adverse to Northfield Bancorp, or violates its obligations with respect to soliciting third-party proposals.

Termination Fee (page )

Under certain circumstances described in the Merger Agreement, in connection with the termination of the Merger Agreement, VSB Bancorp will owe Northfield Bancorp a $2.5 million termination fee. See “Proposal 1—The Merger Proposal—Termination Fee” for a list of the circumstances under which a termination fee is payable.

TABLE OF CONTENTS

Interests of Certain Persons in the Merger that are Different from Yours (page )

Officers and directors of VSB Bancorp have employment and other compensation agreements or economic interests that give them interests in the Merger that are somewhat different from, or in addition to, their interests as VSB Bancorp shareholders. These interests and agreements include:

| • | Northfield Bancorp will establish an advisory board consisting of each of the VSB Bancorp directors (excluding VSB Bancorp’s Chairman of the Board, and excluding VSB Bancorp’s President and Chief Executive Officer if he accepts employment with Northfield Bank or if his participation in the advisory board presents a conflict of interest under applicable law, regulation or existing bank policies or criteria), and such advisory directors are expected to serve for an initial term of two years with compensation of $3,000 per meeting, typically with four meetings per year;

| • | outstanding VSB Bancorp stock options will be converted into the right to receive an amount of cash equal to the difference between the value of the Northfield Bancorp common stock to be received as merger consideration and the exercise price per share of such VSB Bancorp stock option multiplied by the number of shares subject to such VSB Bancorp stock option;

| • | severance or other payments to VSB Bancorp’s President and Chief Executive Officer under his employment agreement, and severance payments to other officers and employees in the event of their termination in connection with the Merger;

| • | a 36-month consulting agreement that is being provided to VSB Bancorp’s Chairman of the Board at a monthly consulting fee of $10,000;

| • | continued employment that has been offered by Northfield Bank to VSB Bancorp’s President and Chief Executive Officer;

| • | accelerated vesting of post-retirement death benefit eligibility under individual split dollar life insurance agreements;

| • | termination of the VSB Bancorp Employee Stock Ownership Plan and repayment of the existing share acquisition loan using VSB Bancorp shares that serve as collateral for the loan, with any remaining unallocated shares to be allocated to eligible participants, including officers; and

| • | rights of VSB Bancorp officers and directors to continued indemnification coverage and continued coverage under directors’ and officers’ liability insurance policies.

The VSB Bancorp board of directors was aware of and considered these interests, among other matters, in evaluating and recommending to the VSB Bancorp shareholders that they adopt the Merger Agreement and the Merger. The aggregate amount that each director and executive officer is expected to receive in connection with the Merger, and based on the assumptions therein, is set forth in “Proposal 1—The Merger Proposal—Merger-Related Executive Compensation for VSB Bancorp’s Named Executive Officers.”

Accounting Treatment of the Merger (page )

The Merger will be accounted for using the acquisition method in accordance with U.S. generally accepted accounting principles.

Comparison of Rights of Shareholders (page )

When the Merger is completed, VSB Bancorp shareholders who receive shares of Northfield Bancorp common stock will become Northfield Bancorp stockholders and their rights will be governed by Delaware law and by Northfield Bancorp’s certificate of incorporation and bylaws. The rights of VSB Bancorp shareholders will change as a result of the Merger due to differences in Northfield Bancorp’s and VSB Bancorp’s governing documents, as well as differences between Delaware and New York law. See “Comparison of Rights of Shareholders” for a summary of the material differences between the respective rights of VSB Bancorp shareholders and Northfield Bancorp stockholders.

Dissenters’ Rights (page )

VSB Bancorp shareholders have dissenters’ rights under the NYBCL in connection with the Merger. VSB Bancorp shareholders who do not vote in favor of the adoption of the Merger Agreement and who otherwise comply with the applicable provisions of the NYBCL will be entitled to dissent and obtain a court

TABLE OF CONTENTS

determination of the “fair value” of their shares of VSB Bancorp common stock. Once the fair value is determined, dissenting VSB Bancorp shareholders may receive cash equal to the fair value of their VSB Bancorp common stock (which may be more or less than the value of the consideration that such holder would be entitled to receive in the Merger) instead of receiving the merger consideration. A VSB Bancorp shareholder electing to dissent from the Merger must strictly comply with all procedures required under Sections 623 and 910 of the NYBCL. If, after the consummation of the Merger, such holder of VSB Bancorp common stock fails to perfect, withdraws or otherwise loses his, her or its rights to dissent with respect to the Merger, each such share will be treated as if it had been converted as of the consummation of the Merger into a right to receive the merger consideration.

You are encouraged to read these provisions carefully and in their entirety. Due to the complexity of the procedures for exercising dissenters’ rights, VSB Bancorp shareholders who are considering exercising such rights should seek the advice of legal counsel. Failure to strictly comply with these provisions will result in the loss of dissenters’ rights with respect to the Merger. The procedures are summarized in “The Dissenters’ Rights” beginning on page , and a copy of the relevant statutory provisions of under Sections 623 and 910 of the NYBCL regarding dissenters’ rights is included as Appendix C.

It is a condition to Northfield Bancorp’s obligation to complete the Merger that the holders of no more than 10% of the shares of VSB Bancorp common stock exercise their rights under Sections 623 and 910 of the NYBCL to dissent from the Merger. See “Proposal 1—The Merger Proposal—Conditions to Completing the Merger” beginning on page .

Material U.S. Federal Income Tax Consequences of the Merger (page )

Northfield Bancorp and VSB Bancorp have each received a legal opinion that the Merger will qualify as a tax-free reorganization within the meaning of Section 368(a) of the Internal Revenue Code. Accordingly, U.S. holders of VSB Bancorp common stock generally will not recognize any gain or loss on the exchange of shares of VSB Bancorp common stock for shares of Northfield Bancorp common stock. However, a U.S. holder of VSB Bancorp common stock generally will recognize gain or loss with respect to cash received instead of a fractional share of Northfield Bancorp common stock that a U.S. holder would otherwise be entitled to receive.

This tax treatment may not apply to all VSB Bancorp shareholders. Determining the actual tax consequences of the Merger to VSB Bancorp shareholders can be complicated. VSB Bancorp shareholders should consult their own tax advisor for a full understanding of the Merger’s tax consequences that are particular to each shareholder.

To review the tax consequences of the Merger to VSB Bancorp shareholders in greater detail, please see the section “Proposal 1—The Merger Proposal—Material U.S. Federal Income Tax Consequences of the Merger.”

Risk Factors (page )

You should consider all the information contained in or incorporated by reference into this Proxy Statement/Prospectus in deciding how to vote for the proposals presented in the Proxy Statement/Prospectus. In particular, you should consider the factors described under “Risk Factors.”

11

TABLE OF CONTENTS

RISK FACTORS

In addition to the other information contained in or incorporated by reference into this Proxy Statement/Prospectus, including the matters addressed under the section titled “Caution About Forward-Looking Statements,” you should consider carefully the risk factors described below in deciding how to vote. You should also read and consider the risk factors associated with the business of Northfield Bancorp because these risk factors may affect the operations and financial results of the combined company. These risk factors may be found in Northfield Bancorp’s Annual Report on Form 10-K for the year ended December 31, 2018.

Because the price of Northfield Bancorp common stock will fluctuate, VSB Bancorp shareholders cannot be certain of the market value of the merger consideration.

Upon completion of the Merger, each share of VSB Bancorp common stock will be converted into the right to receive shares of Northfield Bancorp common stock. The dollar value of the Northfield Bancorp common stock that VSB Bancorp shareholders will receive upon completion of the Merger will depend upon the market value of Northfield Bancorp common stock at the time of completion of the Merger, which may be lower or higher than the ten-day average common stock price of Northfield Bancorp as of the last full trading day preceding public announcement that Northfield Bancorp and VSB Bancorp entered into the Merger Agreement, the last full trading day before the date this Proxy Statement/Prospectus was mailed or the date of the VSB Bancorp special meeting. The market values of Northfield Bancorp common stock and VSB Bancorp common stock have varied since Northfield Bancorp and VSB Bancorp entered into the Merger Agreement and will continue to vary in the future due to changes in the business, operations or prospects of Northfield Bancorp and VSB Bancorp, market assessments of the Merger, regulatory considerations, market and economic considerations, and other factors, most of which are beyond Northfield Bancorp’s and VSB Bancorp’s control. Accordingly, at the time of the VSB Bancorp special meeting, VSB Bancorp shareholders will not know or be able to calculate the number of shares of Northfield Bancorp common stock they would be entitled to receive upon completion of the Merger, and the related value of the merger consideration. You should obtain current market quotations for shares of Northfield Bancorp common stock and for shares of VSB Bancorp common stock before you decide how to vote on the Merger Proposal.

VSB Bancorp will be subject to business uncertainties and contractual restrictions while the Merger is pending.

Uncertainty about the effect of the Merger on employees and customers may have an adverse effect on VSB Bancorp. These uncertainties may impair VSB Bancorp’s ability to attract, retain and motivate key personnel until the Merger is completed, and could cause customers and others who deal with VSB Bancorp to change existing business relationships with VSB Bancorp. VSB Bancorp employee retention and recruitment may be particularly challenging before the effective time of the Merger, as employees and prospective employees may experience uncertainty about their future roles with the combined company.

Completing the Merger and preparing for the integration may place a significant burden on management and internal resources. Any significant diversion of management attention away from ongoing business and any difficulties encountered in the transition and integration process could affect VSB Bancorp’s and Northfield Bancorp’s financial results. In addition, the Merger Agreement requires that VSB Bancorp operate in the usual, regular and ordinary course of business and restricts VSB Bancorp from taking certain actions before the completion or termination of the Merger without Northfield Bancorp’s written consent. These restrictions may prevent VSB Bancorp from pursuing attractive business opportunities that may arise before the completion of the Merger.

The shares of Northfield Bancorp common stock to be received by VSB Bancorp shareholders will have different rights from shares of VSB Bancorp common stock.

Following completion of the Merger, VSB Bancorp shareholders will no longer be shareholders of VSB Bancorp but will instead be stockholders of Northfield Bancorp. There will be important differences between the current rights of VSB Bancorp shareholders and the rights of Northfield Bancorp stockholders that may be important to VSB Bancorp shareholders. See “Comparison of Rights of Shareholders” beginning on page for a discussion of the different rights associated with Northfield Bancorp common stock and VSB Bancorp common stock.

TABLE OF CONTENTS

Failure to complete the Merger could negatively impact the stock price and future business and financial results of VSB Bancorp.

VSB Bancorp has already incurred substantial expenses in connection with the Merger. If the Merger is not completed, the ongoing business of VSB Bancorp may be adversely affected and VSB Bancorp will be subject to several risks, including the following:

| • | if the Merger Agreement is terminated under specified circumstances, VSB Bancorp will be required to pay Northfield Bancorp a $2.5 million termination fee;

| • | VSB Bancorp will be required to pay certain costs relating to the Merger, whether or not the Merger is completed, such as legal, accounting, financial advisory and printing fees;

| • | under the Merger Agreement, VSB Bancorp is subject to certain restrictions on the conduct of its business before completing the Merger, which may adversely affect its operating results; and

| • | matters relating to the Merger may require substantial commitments of time and resources by VSB Bancorp management, which could otherwise have been devoted to other opportunities that may have been beneficial to VSB Bancorp as an independent company.

In addition, if the Merger is not completed, VSB Bancorp may experience negative reactions from the financial markets and from its customers and employees. VSB Bancorp also could be subject to litigation related to any failure to complete the Merger or to enforcement proceedings to perform their respective obligations under the Merger Agreement. If the Merger is not completed, some or all of the risks described above may materialize and may materially affect VSB Bancorp’s business, financial results and stock price.

Northfield Bancorp may be unable to successfully integrate VSB Bancorp’s operations or otherwise realize the expected benefits from the Merger, which could adversely affect Northfield Bancorp’s results of operations and financial condition.

The Merger involves the integration of two companies that have previously operated independently. The difficulties of combining the operations of the two companies include:

| • | integrating personnel with diverse business backgrounds;

| • | converting customers to new systems;

| • | combining different corporate cultures; and

| • | retaining key employees.

The process of integrating operations could cause an interruption of, or loss of momentum in, the activities of the business and the loss of key personnel. The integration of the two companies will require the experience and expertise of certain key employees of VSB Bancorp who are expected to be retained by Northfield Bancorp. Northfield Bancorp may not be successful in retaining these employees for the time period necessary to successfully integrate VSB Bancorp’s operations with those of Northfield Bancorp. The diversion of management’s attention and any delay or difficulty encountered in connection with the Merger and the integration of the two companies’ operations could have an adverse effect on the business and results of operations of Northfield Bancorp following the Merger.

The success of the Merger will depend, in part, on Northfield Bancorp’s ability to realize the anticipated benefits and cost savings from combining the business of VSB Bancorp with Northfield Bancorp. If Northfield Bancorp is unable to successfully integrate VSB Bancorp, the anticipated benefits and cost savings of the Merger may not be realized fully or may take longer to realize than expected. For example, Northfield Bancorp may fail to realize the anticipated increase in earnings and cost savings anticipated to be derived from the Merger. In addition, as with regard to any merger, a significant decline in asset valuations or cash flows may also cause Northfield Bancorp not to realize expected benefits.

The termination fee and the restrictions on solicitation contained in the Merger Agreement may discourage other companies from trying to acquire VSB Bancorp.

Until the completion of the Merger, with some exceptions, VSB Bancorp is prohibited from soliciting, initiating, knowingly encouraging or participating in any discussion of or otherwise considering any inquiry or proposal that may lead to an acquisition proposal, such as a merger or other business combination transaction,

with any person other than Northfield Bancorp. In addition, VSB Bancorp has agreed to pay a $2.5 million termination fee to Northfield Bancorp in specified circumstances. These provisions could discourage other companies that may have an interest in acquiring VSB Bancorp from considering or proposing such an acquisition even though those other companies might be willing to offer greater value to VSB Bancorp’s shareholders than Northfield Bancorp has offered in the Merger. The payment of the termination fee could also have a material adverse effect on VSB Bancorp’s financial condition.

Certain of VSB Bancorp’s officers and directors have interests that are different from, or in addition to, interests of VSB Bancorp shareholders generally, which may create potential conflicts of interest and cause some of these persons to view the proposed transaction differently than you may view it as a VSB Bancorp shareholder.

You should be aware that the directors and officers of VSB Bancorp have interests in the Merger that are different from, or in addition to, the interests of VSB Bancorp shareholders generally. These include: all current VSB Bancorp board members (excluding VSB Bancorp’s Chairman of the Board, and excluding VSB Bancorp’s President and Chief Executive Officer if he accepts employment with Northfield Bank or if his participation in the advisory board presents a conflict of interest under applicable law, regulation or existing bank policies or criteria) will be appointed to a Northfield Bancorp advisory board and expected to serve for an initial term of two years; outstanding VSB Bancorp stock options will vest, if not already vested, and be converted into the right to receive the difference between the merger consideration and the exercise price of the stock options multiplied by the number of shares of VSB Bancorp stock subject to the stock options; continued employment that has been offered by Northfield Bank to VSB Bancorp’s President and Chief Executive Officer; VSB Bancorp’s Chairman of the Board has entered into a 36-month consulting agreement with Northfield Bancorp and Northfield Bank; severance or other payments that VSB Bancorp’s President and Chief Executive Officer may receive under his existing employment agreement; in certain cases, accelerated vesting of post-retirement death benefit eligibility under split dollar agreements; the VSB Bancorp Employee Stock Ownership Plan will be terminated and the existing share acquisition loan repaid from VSB Bancorp shares that serve as collateral for the loan, with any remaining assets in the suspense account allocated to eligible participants, including officers. In addition, the Merger Agreement provides that Northfield Bancorp will provide indemnification of directors and officers and liability insurance for directors and officers of VSB Bancorp for events occurring before the Merger. For a more detailed discussion of these interests, see “Proposal 1—The Merger Proposal—Interests of Certain Persons in the Merger that are Different from Yours.”

VSB Bancorp shareholders will have a reduced ownership and voting interest after the Merger and will exercise less influence over management of the combined organization.

VSB Bancorp shareholders currently have the right to vote in the election of the VSB Bancorp board of directors and on various other matters affecting VSB Bancorp. Upon the completion of the Merger, each VSB Bancorp shareholder will become a stockholder of Northfield Bancorp with a percentage ownership of the combined organization that is significantly smaller than the shareholder’s percentage ownership of VSB Bancorp. It is expected that the former shareholders of VSB Bancorp as a group will receive shares in the Merger constituting approximately _______% of the outstanding shares of Northfield Bancorp common stock immediately after the Merger. As a result, VSB Bancorp shareholders will have significantly less influence on the management and policies of Northfield Bancorp than they now have on the management and policies of VSB Bancorp.

If enough VSB Bancorp shareholders exercise dissenters’ rights, VSB Bancorp and Northfield Bancorp may not be able to complete the Merger or may incur significant additional costs.

VSB Bancorp shareholders are entitled to exercise dissenters’ rights provided by the NYBCL, as described in more detail in the section entitled “Dissenters’ Rights.” If the Merger is completed, a VSB Bancorp shareholder who has complied with applicable requirements under Sections 623 and 910 of the NYBCL may require Northfield Bancorp to pay in cash the appraised value of such shareholders’ dissenting shares instead of the merger consideration. The Merger Agreement contains a closing condition that can only be waived by Northfield Bancorp that dissenting shares will not constitute more than 10% of the outstanding shares of VSB Bancorp common stock. Northfield Bancorp and VSB Bancorp cannot predict the number of shares of VSB Bancorp common stock that will constitute dissenting shares in the Merger, the amount of cash that Northfield

Bancorp may be required to pay following the Merger with respect to the dissenting shares or the expenses that Northfield Bancorp may incur in connection with the appraisal process. If the number of dissenting shares exceeds the percentage described above it could prevent the Merger from being completed.

The fairness opinion received by VSB Bancorp’s board of directors from FinPro does not reflect changes in circumstances subsequent to the date of the fairness opinion and it is limited to financial fairness to VSB Bancorp shareholders.

FinPro delivered to the board of directors of VSB Bancorp an opinion dated December 20, 2019. The opinion does not reflect changes that may occur or may have occurred after the date of the opinion, including changes to the operations and prospects of Northfield Bancorp or VSB Bancorp, changes in general market and economic conditions or regulatory or other factors. Any such changes may materially alter or affect the relative values of Northfield Bancorp and VSB Bancorp. Furthermore, the fairness opinion is limited solely to an opinion regarding the fairness of the Merger to VSB Bancorp shareholders from a financial point of view and does not opine as to any other consequences of the Merger.

Regulatory approvals may not be received, may take longer than expected or may impose conditions that are not presently anticipated.

Before the Merger may be completed, various approvals and consents must be obtained from regulatory entities. These regulators may impose conditions on the completion of the Merger or require changes to the terms of the Merger. Any such conditions or changes could have the effect of delaying completion of the Merger or imposing additional costs on or limiting the revenues of Northfield Bancorp following the Merger.

Either Northfield Bancorp or VSB Bancorp may terminate the Merger Agreement if the Merger has not been completed by October 31, 2020, unless the failure of the Merger to be completed has resulted from the failure of the party seeking to terminate the Merger Agreement to perform its obligations under the Merger Agreement.

Goodwill incurred in the Merger may negatively affect Northfield Bancorp’s financial condition.

To the extent that the value of the shares of Northfield Bancorp common stock issued or to be issued in the Merger exceeds the fair value of the net assets of VSB Bancorp, including identifiable intangibles, that amount will be reported as goodwill by Northfield Bancorp. In accordance with current accounting guidance, goodwill will not be amortized but will be evaluated for impairment annually. A failure to realize expected benefits of the Merger could adversely impact the carrying value of the goodwill recognized in the Merger, and in turn negatively affect Northfield Bancorp’s financial condition.

The price of Northfield Bancorp common stock might decrease after the Merger.

Upon completion of the Merger, holders of VSB Bancorp common stock who receive the merger consideration will become stockholders of Northfield Bancorp. Northfield Bancorp common stock could decline in value after the Merger. For example, during the twelve-month period ending on ______, 2020 (the most recent practicable date before the printing of this Proxy Statement/Prospectus), the closing price of Northfield Bancorp common stock varied from a low of $_____ to a high of $____ and ended that period at $_____. The market value of Northfield Bancorp common stock fluctuates based upon general market conditions, Northfield Bancorp’s business and prospects and other factors. Further, the market price of Northfield Bancorp common stock after the Merger may be affected by factors different from those currently affecting the common stock of Northfield Bancorp or VSB Bancorp. The businesses of VSB Bancorp and Northfield Bancorp differ and, accordingly, the results of operations of the combined company and the market price of the combined company’s shares of common stock may be affected by factors different from those currently affecting the independent results of operations and market prices of common stock of each of VSB Bancorp and Northfield Bancorp. For a discussion of the businesses of VSB Bancorp and Northfield Bancorp and of certain factors to consider in connection with those businesses, see the documents incorporated by reference in this Proxy Statement/Prospectus and referred to under “Where You Can Find More Information” beginning on page .

SPECIAL MEETING OF VSB BANCORP SHAREHOLDERS

Date, Place, Time and Purpose

VSB Bancorp’s board of directors is sending you this document to request that you allow your shares of VSB Bancorp to be represented at the special meeting by the persons named in the enclosed proxy card. At the special meeting, the VSB Bancorp board of directors will ask you to vote on a proposal to adopt the Merger Agreement and the Merger. You may also be asked to vote to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies if there are not sufficient votes at the time of the special meeting to adopt the Merger Agreement and the Merger. The special meeting will be held at [meeting place] at [meeting time], local time, on [Special meeting date].

Who Can Vote at the Meeting

You are entitled to vote if the records of VSB Bancorp show that you held shares of VSB Bancorp common stock as of the close of business on [record date]. As of the close of business on that date, [shares outstanding] shares of VSB Bancorp common stock were outstanding. If you are a beneficial owner of shares of VSB Bancorp common stock held by a broker, bank or other nominee (i.e., in “street name”) and you want to vote your shares in person at the meeting, you will have to get a written proxy in your name from the broker, bank or other nominee who holds your shares.

Quorum; Vote Required

The special meeting will conduct business only if the holders of at least one third (33 1/3%) of the shares of VSB Bancorp common stock entitled to vote at the special meeting are represented in person or by proxy at the meeting. If you return valid proxy instructions or attend the meeting in person, your shares will be counted to determine whether there is a quorum, even if you abstain from voting. Broker non-votes also will be counted to determine the existence of a quorum. A broker non-vote occurs when a broker, bank or other nominee holding shares of VSB Bancorp common stock for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received voting instructions from the beneficial owner.

Proposal 1: Adoption of the Merger Agreement and the Merger. Adoption of the Merger Proposal will require the affirmative vote of the holders of a majority of the shares of VSB Bancorp common stock entitled to vote at the special meeting. Abstentions and broker non-votes will have the same effect as shares voted against the Merger Agreement and the Merger. Failure to return a properly executed proxy card or to vote in person will have the same effect as a vote against the Merger Agreement and the Merger.

Proposal 2: Adjourn the special meeting, if necessary or appropriate, including an adjournment to permit further solicitation of proxies in favor of the Merger Agreement. Approval of the Adjournment Proposal will require the affirmative vote of a majority of the votes cast at the special meeting. Abstentions and broker non-votes will not affect whether the proposal is approved.

Shares Held by VSB Bancorp Officers and Directors and by Northfield Bancorp

As of [record date], directors, and executive officers of VSB Bancorp and their affiliates beneficially owned [insider shares] shares of VSB Bancorp common stock, not including shares that may be acquired upon the exercise of stock options. This equals [insider ownership]% of the outstanding shares of VSB Bancorp common stock, and represents % of the votes required to approve the Merger Proposal. The directors and executive officers of VSB Bancorp have agreed to vote the shares over which they have voting control, or % of the outstanding shares, in favor of the Merger Agreement and the Merger at the special meeting. As of the same date, Northfield Bancorp and its subsidiaries and its directors and executive officers did not own any shares of VSB Bancorp common stock.

VSB Bancorp shareholders are entitled to dissent from the Merger and obtain the fair value of their VSB Bancorp common stock in cash in accordance with the procedures established by New York law.

Sections 623 and 910 of the NYBCL provide that, if the Merger is consummated, holders of VSB Bancorp common stock who object to the Merger in writing prior to the vote by the holders of VSB Bancorp common stock on the Merger Proposal and who follow the procedures specified in Section 623 (summarized below) will have the right to receive a cash payment of the fair value of their VSB Bancorp common stock. A copy of Section 623 and Section 910 of the NYBCL is attached as Appendix C to this Proxy Statement/Prospectus. The procedures of Section 623 must be followed precisely. If they are not, a holder of VSB Bancorp common stock will lose his, her or its right to dissent. As described more fully below, such “fair value” would potentially be determined in judicial proceedings, the result of which cannot be predicted. Holders of VSB Bancorp common stock exercising dissenters’ rights may not receive consideration equal to or greater than the value of the Northfield Bancorp common stock to be issued to them in the Merger. Holders of VSB Bancorp common stock exercising dissenters’ rights who receive a cash payment for their shares will, in most cases, be treated as having sold their shares for cash for federal, state and local income tax purposes.

The statutory procedures outlined below are complex. What follows is a summary, which is qualified in its entirety by reference to the full text of Section 623 and Section 910 of the NYBCL. Holders of VSB Bancorp common stock wishing to exercise their dissenters’ rights should consult with their legal advisors to ensure that they fully and properly comply with the requirements of New York law.

If any holder of shares of VSB Bancorp common stock who exercises dissenters’ rights withdraws or loses (through failure to perfect or otherwise) the right to obtain payment for such holder’s shares under Sections 623 and 910 of the NYBCL, then such VSB Bancorp shareholder’s shares will be converted, or will be treated as if they had been converted, into the right to receive the merger consideration, without interest and subject to any applicable withholding of taxes if the Merger is completed. VSB Bancorp will not provide you with any notice regarding your dissenters’ rights other than as described in this Proxy Statement/Prospectus and the notice of special meeting included with this Proxy Statement/Prospectus.

Requirements for Exercising Dissenters’ Rights

Any holder of VSB Bancorp common stock will have the right to receive a cash payment of the fair value of his, her or its VSB Bancorp common stock and the other rights and benefits provided in Sections 623 and 910, if such VSB Bancorp shareholder:

| • | does not vote in favor of the adoption of the Merger Agreement; and

| • | files with VSB Bancorp a written objection to the Merger prior to the vote by the holders of VSB Bancorp common stock on the adoption of the Merger Agreement. The written objection must include:

| • | notice of the holder of VSB Bancorp common stock’s election to dissent;

| • | the name and residence address of the dissenting holder of VSB Bancorp common stock;

| • | the number of shares of VSB Bancorp common stock as to which the holder of such common stock dissents; and

| • | a demand for payment of the fair value of such VSB Bancorp common stock if the Merger Agreement is adopted and the Merger is consummated.

A vote against adoption of the Merger Agreement will not satisfy the requirement of filing a written objection. Failure to vote against adoption of the Merger Agreement will not waive a VSB Bancorp shareholder’s right to receive payment if the VSB Bancorp shareholder has filed a written objection in accordance with Section 623 and has not voted in favor of adoption of the Merger Agreement. If a VSB Bancorp shareholder abstains from voting on adoption of the Merger Agreement, this will not waive his, her or its dissenter’s rights so long as the appropriate written objection to the Merger is properly and timely filed.

Since a signed and dated proxy left blank will be voted for adoption of the Merger Agreement and the transactions contemplated thereby, including the Merger, any VSB Bancorp shareholder who wishes to exercise his, her or its dissenter’s rights must either vote against adoption of the agreement, abstain or not submit a signed and dated proxy without a voting instruction. Written objection at this time may not be required from any VSB

Bancorp shareholder to whom VSB Bancorp did not give proper notice of the special meeting of VSB Bancorp shareholders contemplated by this Proxy Statement/Prospectus.

A holder of VSB Bancorp common stock may not dissent as to less than all VSB Bancorp common stock held of record that he or she owns beneficially. A nominee or fiduciary may not dissent on behalf of any beneficial owner of VSB Bancorp common stock as to less than all VSB Bancorp common stock of such owner held of record by the nominee or fiduciary.

All written objections to the Merger and notices of election to dissent should be addressed to:

VSB Bancorp, Inc.
4142 Hylan Boulevard
Staten Island, New York 10308
Attention: Raffaele M. Branca

If the Merger Agreement is adopted by holders of VSB Bancorp common stock, then within ten days after such adoption, VSB Bancorp will give written notice of the adoption by registered mail to each holder of VSB Bancorp common stock who filed a timely written objection or from whom objection was not required, except for any VSB Bancorp shareholder who voted in favor of adoption of the Merger Agreement. Any holder of VSB Bancorp common stock from whom objection was not required and who elects to dissent must file with VSB Bancorp, within 20 days after the giving of notice to him, her or it, a written notice of election to dissent, stating his, her or its name and residence address, the amount of VSB Bancorp common stock as to which he, she or it dissents and a demand for payment of the fair value for his, her or its VSB Bancorp common stock.

Either at the time of filing of the notice of election to dissent or within one month thereafter, a dissenting VSB Bancorp shareholder must submit the certificates representing his, her or its dissenting VSB Bancorp shares to VSB Bancorp or its transfer agent. VSB Bancorp will note conspicuously on the certificates that a notice of election has been filed and will then return the certificates to the VSB Bancorp shareholder. Any VSB Bancorp shareholder who fails to submit his, her or its certificates for notation within the required time shall, at the option of VSB Bancorp upon written notice to such VSB Bancorp shareholder within 45 days from the date of filing such notice of election to dissent, lose his, her or its dissenter’s rights unless a court, for good cause shown, otherwise directs.

Within 15 days after the expiration of the period within which VSB Bancorp shareholders may file their notices of election to dissent, or within 15 days after the completion of the Merger, whichever is later (but in no case later than 90 days after VSB Bancorp shareholders adopt the Merger Agreement), the surviving corporation will make a written offer by registered mail to each VSB Bancorp shareholder who has filed a notice of election, to pay for his, her or its dissenting shares at a specified price, which the surviving corporation considers to be their fair value. If the Merger has occurred, the surviving corporation must accompany the offer by an advance payment to each VSB Bancorp shareholder who has submitted his, her or its stock certificates of an amount equal to 80% of the amount of the offer. Acceptance of such payment does not constitute a waiver of any dissenters’ rights. The offer must be made at the same price per share to all the dissenting VSB Bancorp shareholders. If, within 30 days after the making of an offer, the surviving corporation and any dissenting VSB Bancorp shareholders agree on the price to be paid for dissenting shares, the balance of payment for the shares must be made within 60 days after the making of the offer or the completion of the Merger, whichever is later, and upon surrender of the certificates representing such shares of VSB Bancorp common stock.

If the surviving corporation fails to make an offer to dissenting VSB Bancorp shareholders within the 15-day period described above, or if it makes the offer and any dissenting VSB Bancorp shareholder fails to agree with the surviving corporation within 30 days thereafter upon the price to be paid for his, her or its shares, VSB Bancorp is required, within 20 days after the expiration of whichever is the applicable of the two periods, to institute a special proceeding in the supreme court in the judicial district in which the office of the surviving corporation is located to determine the rights of dissenting VSB Bancorp shareholders and to fix the fair value of their shares. If VSB Bancorp fails to institute a proceeding within the 20-day period, any dissenting VSB Bancorp shareholder may institute a proceeding for the same purpose not later than 30 days after the expiration of the 20-day period. If a dissenting VSB Bancorp shareholder does not institute a proceeding within the 30-day period, all dissenters’ rights are lost unless the court, for good cause shown, otherwise directs.

TABLE OF CONTENTS

During each proceeding, the court will determine whether each dissenting VSB Bancorp shareholder is entitled to receive payment for his, her or its shares and, if so, will fix the value of such shares, which will be the fair value, as of the close of business on the day prior to the date VSB Bancorp shareholders voted to adopt the Merger Agreement, taking into consideration the nature of the transaction giving rise to the VSB Bancorp shareholder’s right to receive payment for his, her or its dissenting shares and its effects on the surviving corporation and VSB Bancorp’s shareholders, the concepts and methods then customary in relevant securities and financial markets for determining the fair value of shares of a corporation engaging in a similar transaction under comparable circumstances and all other relevant factors. The court will determine the fair value of the shares without a jury and without referral to an appraiser or referee. The court will also include an allowance for interest on such amount to be paid from the completion of the Merger to the date of payment at such rate as the court finds equitable, taking into account all relevant factors, including the rate of interest that the surviving corporation would have had to pay to borrow money during the pendency of the proceeding, unless the court finds that a VSB Bancorp shareholder’s refusal to accept VSB Bancorp’s or the surviving corporation’s offer of payment was arbitrary, vexatious or otherwise not in good faith, in which case no interest will be awarded.

Each party to such proceeding will bear such party’s own costs and expenses. The court may, in its discretion, apportion and assess all or any part of the costs, expenses and fees incurred by VSB Bancorp or the surviving corporation against any or all of the dissenting VSB Bancorp shareholders who are parties to the proceeding, if the court finds that the VSB Bancorp shareholder’s refusal to accept the surviving corporation’s offer was arbitrary, vexatious or otherwise not in good faith, in which case VSB Bancorp’s or the surviving corporation’s costs may, in the discretion of the court, be assessed against any or all dissenting VSB Bancorp shareholders who are parties to such proceeding. The court, in its discretion, may also apportion or assess any part of the dissenting VSB Bancorp shareholder’s costs against the surviving corporation if it finds that the fair value of the shares as determined materially exceeds the amount that the surviving corporation offered to pay, or that no offer or advance payment was made by the surviving corporation, or that the surviving corporation failed to institute such special proceeding within the specified period, or that the action of VSB Bancorp in complying with its obligations under Section 623 was arbitrary, vexatious or otherwise not in good faith. Within 60 days following the final determination of the proceeding, the surviving corporation will pay to each dissenting VSB Bancorp shareholder the amount found to be due him or her, upon the VSB Bancorp shareholder’s surrender of all certificates representing dissenting shares.

The enforcement by a VSB Bancorp shareholder of his, her or its right to receive payment for shares in accordance with Section 623 excludes the enforcement by such VSB Bancorp shareholder of any other right to which he, she or it might otherwise be entitled by virtue of his, her or its ownership of shares (unless the VSB Bancorp shareholder withdraws his, her or its notice of election or the Merger is abandoned), except that the VSB Bancorp shareholder will retain the right to bring or maintain an appropriate action to obtain relief on the grounds that the Merger will be or is unlawful or fraudulent as to him or her. A VSB Bancorp shareholder’s notice of election may be withdrawn at any time prior to his, her or its acceptance in writing of an offer to purchase his, her or its dissenting shares by VSB Bancorp, but no withdrawal may be made later than 60 days from the completion of the Merger (unless VSB Bancorp failed to make a timely offer, in which case a withdrawal may be made no later than 60 days after such offer is made) without the written consent of VSB Bancorp. In order for a withdrawal of a VSB Bancorp shareholder’s notice of election to be effective, it must be accompanied by a return to VSB Bancorp of any advance payment made to such VSB Bancorp shareholder.

If the Merger Agreement is adopted by the requisite vote of the shareholders of VSB Bancorp at the special meeting, then following the closing of the Merger, Northfield Bancorp will assume the obligations of VSB Bancorp under Sections 623 and 910.

PROPOSAL 1 - THE MERGER PROPOSAL

The following summary of the Merger Agreement is qualified by reference to the complete text of the Merger Agreement. A copy of the Merger Agreement is attached as Appendix A to this Proxy Statement/Prospectus and is incorporated by reference into this Proxy Statement/Prospectus. You should read the Merger Agreement completely and carefully as it, rather than this description, is the legal document that governs the Merger.

General

The Merger Agreement provides for the merger of VSB Bancorp with and into Northfield Bancorp, with Northfield Bancorp as the surviving entity. Following the merger of VSB Bancorp with and into Northfield Bancorp, Victory State Bank will merge with and into Northfield Bank, with Northfield Bank as the surviving bank.

Background of the Merger

VSB Bancorp’s board of directors and management have periodically reviewed and assessed strategic opportunities and challenges. The board of directors has considered the difficulty in growing profitably and operating a publicly-traded community financial institution under current economic and competitive conditions. At the same time, like many other smaller financial institutions, VSB Bancorp has experienced increasing costs for technology and regulatory compliance. As part of the board of directors’ and management’s evaluation of ways to meet these challenges, they routinely have considered both internal growth strategies and strategic business combinations as means of achieving economies of scale.

On October 8, 2013, Joseph J. LiBassi, Chairman of the Board of VSB Bancorp, at a meeting of the board of directors of VSB Bancorp, advised the board that he had met with the Chairman of the board of directors of a bank holding company (“Company A”) who had expressed an interest in engaging in a business combination with VSB Bancorp. Mr. LiBassi suggested that an appropriate valuation of VSB Bancorp might generate a price range of $23.00 to $25.00 per share of VSB Bancorp common stock. The board discussed its view of the different parameters of a potential merger transaction. The board called legal counsel by telephone, who reviewed the obligations and fiduciary duties of the board in pursuing such a transaction.

Following the meeting, upon the authorization of the board of directors, VSB Bancorp negotiated an engagement agreement with a financial advisor in connection with a possible business combination transaction.

On October 15, 2013, Messrs. LiBassi and Branca updated the board on the financial terms under discussion that involved a price range of $23.00 to $25.00 per share in an all-stock transaction.

After due diligence, Company A reduced its price indication to $21.00 per share. Despite further discussions with Company A and its representatives, Company A refused to increase its price indication, and therefore discussions terminated.

In April 2014, as part of its annual strategic planning work for VSB Bancorp, the financial advisor presented to the board a list of ten financial institutions that it thought might be interested in a business combination with VSB Bancorp. The board authorized the financial advisor to solicit indications of interest. Four companies, after conducting preliminary due diligence, presented letters of intent, three of which provided pricing at significantly below $20.00 per share, and were therefore not considered worthy of further discussion. One company submitted a letter of intent with a price indication of $22.50 per share in an all-stock transaction. However, after evaluating the stock being offered as currency in that proposal, VSB Bancorp concluded that the company proposing the $22.50 per share offer had numerous fundamental weaknesses and, as a result, determined not to proceed with that company.

One additional bank holding company (“Company B”) expressed interest, and it signed a confidentiality agreement on May 6, 2014. On January 21, 2015, VSB Bancorp received a letter of intent from Company B to acquire VSB Bancorp at a price of $21.00 per share. The board met on February 10, 2015 with its financial advisor to discuss the proposed letter of intent. After discussion, the board authorized Mr. LiBassi to execute the letter of intent on the terms discussed. Company B then conducted due diligence after which it advised VSB Bancorp that it had decided not to go forward.

After the expiration of its engagement letter with the original financial advisor, VSB Bancorp engaged a different investment banker to act as its independent financial advisor in connection with a possible business combination. In August 2016, that investment banker obtained a draft letter of intent for a business combination from Northfield Bancorp.

TABLE OF CONTENTS

The board met on August 9, 2016 and Mr. LiBassi updated the board on conversations that he had with senior officers of Northfield Bancorp. He reported a price indication at 150% of book value and that VSB Bancorp’s board would not be given representation on Northfield Bancorp’s board of directors. After discussion and a presentation from its financial advisor, the board authorized Mr. LiBassi and Mr. Branca to seek and review a letter of intent from Northfield Bancorp on the terms discussed.

Northfield Bancorp then delivered a letter of intent to engage in an all-stock transaction with VSB Bancorp with a price of $24.55 per share based on a fixed exchange ratio. The board met on August 19, 2016, to discuss the letter of intent and the due diligence process. VSB Bancorp’s legal advisor had prepared a form of non-disclosure agreement to be executed by Northfield Bancorp prior to VSB Bancorp providing due diligence information. The board authorized Messrs. LiBassi and Branca to execute the non-disclosure agreement and proceed with due diligence.

The board met on August 19, 2016 and on September 2, 2016 to discuss the proposed revised letter of intent. Representatives of its financial advisor attended the September 2 board meeting and reviewed the final terms of the proposal with the board.

The board met again on September 7, 2016 for an update on the status of negotiations. VSB Bancorp’s financial advisor reviewed the revised offer from Northfield Bancorp, which included a floating exchange ratio.

The board of VSB Bancorp met again on September 13, 2016 to further discuss the proposal and anticipated timing of next steps.

Due diligence continued and on September 21, 2016, VSB Bancorp’s legal advisor received a draft definitive agreement from the attorneys for Northfield Bancorp. On October 11, 2016, Mr. Branca and Mr. LiBassi were contacted by the then-Chief Executive Officer of Northfield Bancorp, who indicated that Northfield Bancorp was withdrawing its offer because of VSB Bancorp’s construction lending portfolio that was located in New York City but outside Staten Island.

As the result of a pre-existing business relationship and at the recommendation of an investment banker not retained by VSB Bancorp, Mr. Branca met with the President and Chief Executive Officer of another bank holding company (“Company C”) in January 2017, with a follow-up meeting also attended by Mr. LiBassi in February 2017. The President of Company C discussed the possibility of a business combination. Mr. Branca and Mr. LiBassi rejected the overture because Company C’s stock was considered to be undesirable.

In June 2018, at the initiation of the President of Company A, Messrs. LiBassi and Branca met with executive officers of Company A to renew discussions regarding a possible business combination. On July 3, 2018, Company A delivered an indication of interest to acquire VSB Bancorp for $27.75 per share in a transaction consisting of 65% to 75% stock and the remainder in cash. The board of directors of VSB Bancorp met on July 3, 2018 to discuss the terms of the letter of intent. The board deemed this proposal to be inadequate at the time because VSB Bancorp stockholders would be subject to fluctuation in the stock price of Company A and because the offer was not all stock and thus some stockholders might be forced to recognize taxable income. The board thus rejected the offer.

In September 2018, Northfield Bancorp approached VSB Bancorp again and presented a new proposed letter of intent. The board met on September 11, 2018 to discuss the proposal. Mr. Branca advised the board that the proposal was an all-stock transaction at a price of $29.75 per share with a floating exchange ratio with a 5% cap and collar, a 15% double trigger walkaway, current payment of a quarterly cash dividend equivalent to $0.19 per share as adjusted for the projected exchange ratio, and a payout in cash of outstanding unexercised options. The price offered would equate to approximately 160% of VSB Bancorp’s book value per share at June 30, 2018. Northfield Bancorp wanted Mr. LiBassi to enter into a three-year consulting contract (with a non-competition provision) at $120,000 per annum. There would be a two-year advisory board for current board members at a per meeting fee of $2,000 per quarter. The change in control payment in Mr. Branca’s employment contract would be paid and he would receive a job offer from Northfield Bancorp. All VSB Bancorp employees who are not retained will receive severance under the VSB Bancorp severance plan.

On October 18, 2018, Northfield Bancorp’s attorneys presented the attorneys for VSB Bancorp with a draft definitive agreement, which was substantially similar to the agreement that had been negotiated in 2016, but at a revised price of $29.75 per share. However, before negotiations on the definitive agreement were undertaken, Northfield Bancorp withdrew its offer because a decrease in the market price of Northfield Bancorp common stock would have required Northfield Bancorp to issue more shares than Northfield Bancorp thought was appropriate.

TABLE OF CONTENTS

In July 2019, a consultant for Company B met with Messrs. LiBassi and Branca to explore whether discussions regarding a transaction with Company B might be acceptable. The consultant indicated that the President of Company B was focused on a price to book value multiple in the range of approximately 135%. Based upon discussions with Northfield Bancorp and knowledge of the market values at which bank merger transactions were then being consummated, Messrs. LiBassi and Branca believed that a price to book value multiple between 130% to 140% was inadequate. They advised the consultant that further discussions would not be appropriate without an increase in the price to book multiple to then-current multiples, which were in excess of 150% of book value. VSB Bancorp received no further contact from the representatives of Company B.

In August 2019, at the invitation of a different investment banker, Mr. Branca met with the President of another bank holding company (“Company D”), with a follow-up meeting in November 2019. Company D expressed an interest in a business combination with VSB Bancorp. No price was discussed and no letter of intent was received from Company D.

In October 2019, an attorney at Gallet Dreyer & Berkey, LLP, attorneys for VSB Bancorp, was approached by the Chairman of the board of directors of a New York chartered bank (“Company E”). The Chairman inquired as to whether VSB Bancorp would be interested in a business combination. No prices or other terms were discussed, except that the Chairman explained that Company E was interested solely in an all-stock transaction. The attorney reported the conversation to Messrs. LiBassi and Branca. They advised him that because the stock being offered was completely illiquid and there was one large control stockholder, the proposed transaction was undesirable, and they were not interested in further discussions.

In November 2019, the President of Northfield Bancorp approached Mr. Branca to renew business combination discussions. They discussed pricing based upon a VSB Bancorp book multiple of approximately 160% based upon projected VSB Bancorp book value per share at year-end 2019. The board of directors of VSB Bancorp met on November 27, 2019 to discuss this proposal. The proposed terms were substantially similar to the terms and structure discussed in 2018, but with a purchase price dependent upon projected year-end book value that Mr. Branca suggested could be as high as $33.36 per share. The board discussed the transaction and authorized Mr. Branca and Mr. LiBassi to engage in further discussions to seek to finalize a transaction on the terms discussed.

The legal advisor for Northfield Bancorp delivered a draft of a definitive agreement to the legal advisors for VSB Bancorp on December 6, 2019. The agreement was substantially similar to the agreement that had been negotiated in 2016 and that had again been presented in 2018, but with a fixed price and a floating exchange ratio within certain parameters. The parties continued to discuss the calculation of the exchange ratio. Northfield Bancorp proposed a determination of the exchange ratio based upon the ten-day average trading price of Northfield Bancorp common stock measured from the date on which all required regulatory approvals of the transaction are received. In order to increase price certainty and avoid risks of fluctuations in Northfield Bancorp’s stock price after the exchange ratio had been set, VSB Bancorp sought, and Northfield Bancorp agreed, that the exchange ratio would be determined based upon the ten-day average closing price measured from five trading days prior to closing. After a review of financial data, a price of $33.30 per share of VSB Bancorp common stock was agreed upon.

A draft of the definitive agreement was circulated to the board of VSB Bancorp on December 18, 2019. The board met by telephone on December 19, 2019. An attorney at Gallet Dreyer & Berkey LLP, VSB Bancorp’s legal advisor, reviewed negotiations with the board and discussed the definitive agreement. VSB Bancorp’s legal advisor then discussed all significant terms of the transaction. VSB Bancorp’s legal advisor also discussed the consulting agreement to be entered into by Mr. LiBassi and the advisory board provisions and explained a preference for two separate votes by each of the VSB Bancorp board and by the Victory State Bank board, one with Messrs. Branca and LiBassi not voting and one with them voting. He explained that the separate votes were appropriate because of the additional benefits that Messrs. LiBassi and Branca would obtain from the transaction.

Mr. Branca then advised the board of the status of his discussions with Northfield Bancorp regarding continued employment. Mr. Branca also advised the board that VSB Bancorp had retained FinPro to render a fairness opinion on the transaction.

On December 18, 2019, Northfield Bancorp’s board of directors held a meeting at which representatives of Northfield Bancorp’s senior management, Sandler O’Neill & Partners, L.P. (“Sandler O’Neill”), Northfield Bancorp’s financial adviser and Luse Gorman, PC, Northfield’s legal counsel, were present. A representative of

TABLE OF CONTENTS

Sandler O’Neill reviewed the financial analysis of the transaction. Northfield Bancorp’s board of directors received a report from executive management on the results of the legal and business due diligence review of VSB Bancorp. A representative of Luse Gorman reviewed in detail the terms of the merger agreement.

On December 20, 2019, at a meeting of the board of directors, a representative of FinPro went through a detailed analysis of the financial terms of the transaction and then rendered its oral opinion to the board that the proposed transaction was fair to the shareholders of VSB Bancorp from a financial point of view. The representative of FinPro then said that the final written fairness opinion, matching the oral opinion he had just delivered, would be delivered the following business day.

On December 20, 2019, after discussions and questions of its legal advisor and FinPro, the board of directors of VSB Bancorp unanimously approved the transaction and unanimously authorized management to proceed to execute the definitive agreement and take all actions necessary to consummate it by two separate votes (with and without Messrs. LiBassi and Branca).

On December 23, 2019, Northfield Bancorp’s board of directors held a meeting at which representatives of Northfield Bancorp’s executive management, Sandler O’Neill and Luse Gorman were present. A representative of Sandler O’Neill reviewed the financial analysis supporting its proposed fairness opinion. After discussion among Northfield Bancorp’s board of directors and its advisors, representatives of Sandler O’Neill delivered an oral opinion, confirmed by delivery of a written opinion, dated December 23, 2019, to Northfield Bancorp’ s board of directors to the effect that, as of such date and based on and subject to the qualifications, limitations and assumptions stated in its opinion, the merger consideration to be paid by Northfield Bancorp in the proposed merger was fair to Northfield Bancorp from a financial point of view. The Northfield Bancorp board of directors then unanimously approved the Merger Agreement.

VSB Bancorp’s Reasons for the Merger; Recommendation of VSB Bancorp’s Board of Directors

In reaching its unanimous decision to adopt the Merger Agreement, the Merger and the other transactions contemplated by the Merger Agreement, and to recommend that VSB Bancorp shareholders adopt the Merger Agreement, the VSB Bancorp board evaluated the Merger in consultation with VSB Bancorp’s management, as well as VSB Bancorp’s outside legal advisor and FinPro, and considered a number of factors, including the following:

| • | the time that the board anticipated it would take for VSB Bancorp to implement its business strategy of growing the franchise and improving earnings through increasing the size of the loan portfolio, and the timetable for growth in VSB Bancorp’s franchise value, compared with the ability to immediately realize a substantial premium to its current market value by entering into a business combination with Northfield Bancorp;

| • | the risk that VSB Bancorp would be unable to implement its growth strategy and increase loans due to competition, external economic conditions and other factors outside the control of management;

| • | other risks of remaining independent, including the challenges of the current financial, operating, regulatory and interest rate environment; the increasing costs associated with banking regulation, compliance and technology; and the anticipated costs of continuing to develop and enhance VSB Bancorp’s business capabilities;

| • | the history of VSB Bancorp’s board’s review and evaluation of other prior offers, the prices and terms associated with those offers, and advice of its financial advisors previously received in connection with those prior offers;

| • | that the board was able to negotiate merger consideration that had a reasonable level of price certainty that, at $33.30 per share, represented a 51.4% premium over the trading price for VSB Bancorp’s common stock on December 19, 2019 of $22.00, while maintaining the right to terminate the transaction if there is a 15% decline in Northfield Bancorp’s stock price and a 15% decline in Northfield Bancorp’s stock price relative to a peer index, in each case measured close to the closing;

| • | VSB Bancorp shareholders will receive the Northfield Bancorp stock in exchange for their VSB Bancorp stock without current income tax recognition of the gain;

| • | VSB Bancorp shareholders will have the opportunity to participate in the potential of future earnings and growth of the combined company;

33

TABLE OF CONTENTS

| • | although future dividends are not guaranteed, that the dividend yield on Northfield Bancorp common stock, based upon the amount of the last dividend paid by Northfield Bancorp (and past dividend practices of Northfield Bancorp) and the Northfield Bancorp closing price on December 19, 2019, after adjustment for the projected exchange ratio, was higher than VSB Bancorp’s current dividend yield;

| • | that the cultural and geographic similarities between Northfield Bancorp and VSB Bancorp, both of which are headquartered on Staten Island, provide an easy transition for VSB Bancorp customers and give them a broadened local branch network at which they can conduct their operations;

| • | the likelihood of receiving the required regulatory approvals due to the strength of the two constituent banks and the resulting likelihood that the Merger can be completed in a timely manner;

| • | the written opinion of FinPro, dated as of December 20, 2019, to the effect that, based on and subject to the various assumptions, considerations, qualifications and limitations set forth in the opinion, as of the date of the opinion, the consideration to be received in the Merger was fair to the holders of VSB Bancorp common stock from a financial point of view, as more fully described below under “—Opinion of FinPro Capital Advisors for VSB Bancorp’s Board of Directors”;

| • | that the exchange ratio is variable, subject to the 5% collar, which the VSB Bancorp board believed was important in providing improved price certainty to VSB Bancorp shareholders;

| • | the geographic and strategic fit of the branch networks of the combined company and the scale, scope, strength and diversity of operations, product lines and delivery systems that could be achieved by the combined company;

| • | the impact of the Merger on employees, customers and communities served by VSB Bancorp and the expectation that the combined company will continue to provide high quality service to the communities and customers currently served by VSB Bancorp; and

| • | the existence of protections in the Merger Agreement that strengthen the ability of the VSB Bancorp board to exercise its fiduciary duty to the shareholders of VSB Bancorp, including:

| • | that, under certain circumstances, VSB Bancorp may furnish non-public information to, and enter into discussions with, a third party that makes a qualifying acquisition proposal, as more fully described under “Additional Covenants of VSB Bancorp and Northfield Bancorp in the Merger Agreement—Agreement Not to Solicit Other Offers”; and

| • | that both parties’ covenant to use their reasonable best efforts to obtain the required regulatory approvals for the Merger.

The VSB Bancorp board also considered a number of potential risks and uncertainties in connection with its consideration of the Merger, including, without limitation, the following:

| • | the regulatory and other approvals required in connection with the Merger and the possibility that such regulatory approvals may not be received in a timely manner and may include the imposition of burdensome conditions;

| • | the possibility of disruption to VSB Bancorp’s business that could result from the announcement of the Merger on VSB Bancorp’s operations or stock price;

| • | the potential for diversion of management and employee attention, and for employee attrition, during the period before the completion of the Merger and the potential effect on VSB Bancorp’s business and relations with customers, service providers and other stakeholders, whether or not the Merger is completed;

| • | the Merger Agreement’s provisions that generally require VSB Bancorp to conduct its business in the ordinary course and the Merger Agreement’s other restrictions on the conduct of VSB Bancorp’s business before the completion of the Merger, which may delay or prevent VSB Bancorp from undertaking business opportunities that may arise pending completion of the Merger;

| • | that due to the cap and collar, VSB Bancorp’s shareholders have limited price protection;

| • | the possibility that the expected benefits and synergies sought in the Merger, including cost savings and Northfield Bancorp’s ability to successfully market its financial products to VSB Bancorp’s customers, may not be realized or may not be realized within the expected time period, thereby resulting in downward pressure on Northfield Bancorp’s stock price;

TABLE OF CONTENTS

| • | certain provisions of the Merger Agreement that prohibit VSB Bancorp from soliciting, and limit its ability to respond to, proposals for alternative business combinations;

| • | the risk of litigation arising from shareholders in respect of the Merger Agreement or the Merger;

| • | VSB Bancorp’s obligation to pay Northfield Bancorp a termination fee of $2.5 million in certain circumstances, as described under “—Termination Fee,” which may deter other companies from proposing an alternative transaction that may be more advantageous to VSB Bancorp shareholders;

| • | that VSB Bancorp’s directors and executive officers may have interests in the Merger that are different from or in addition to those of VSB Bancorp shareholders generally, as described under “—Interests of Certain Persons in the Merger that are Different from Yours”; and

| • | that, while the Merger is expected to be completed, there are no assurances that all conditions to the parties’ obligations to complete the Merger will be satisfied or waived (if applicable), and as a result, it is possible that the Merger may not be completed, in which case VSB Bancorp will have incurred significant expense and significant disruption of its normal operations, such as diversion of management attention and employee attrition.

The foregoing discussion of the information and factors considered by the VSB Bancorp board is not exhaustive, but includes the material factors considered by the VSB Bancorp board. The above factors are not presented in any order of priority. In view of the wide variety of factors considered by the VSB Bancorp board in connection with its evaluation of the Merger and the complexity of these matters, the VSB Bancorp board did not attempt to quantify, rank or otherwise assign relative weights to specific factors that it considered in reaching its decision. Furthermore, in considering the factors described above, individual members of the VSB Bancorp board may have given different weights to different factors. The VSB Bancorp board evaluated the factors described above and reached the unanimous decision that the Merger is advisable and in the best interests of VSB Bancorp and its shareholders. The VSB Bancorp board realized there can be no assurance about future results, including results expected or considered in the factors listed above. However, the VSB Bancorp board concluded the potential positive factors outweighed the potential risks of completing the Merger.

This explanation of the VSB Bancorp board’s reasoning and all other information presented in this section is forward looking in nature and, therefore, should be read in light of the factors described under “Cautionary Statement Regarding Forward-Looking Statements.”

On the basis of these considerations, VSB Bancorp’s board unanimously adopted the Merger Agreement and the transactions contemplated thereby and recommends that VSB Bancorp’s shareholders vote “FOR” the adoption of the Merger Agreement and the Merger and “FOR” the approval of the Adjournment Proposal.

Opinion of FinPro Capital Advisors for VSB Bancorp’s Board of Directors

VSB Bancorp engaged FinPro Capital Advisors, Inc. (“FinPro”) to provide its opinion as to the fairness, from a financial point of view, to VSB Bancorp shareholders, of the consideration as proposed in the Merger Agreement, to be received by VSB Bancorp’s common equity shareholders in the Merger. FinPro is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions. VSB Bancorp selected FinPro because of its knowledge of, experience with, and reputation in the financial services industry.

VSB Bancorp’s board of directors considered and approved the Merger Agreement at a board of directors meeting held on December 20, 2019. FinPro delivered to the board of directors a fairness opinion presentation concluding that the merger consideration was fair to VSB Bancorp shareholders from a financial point of view.

The text of FinPro’s written opinion is attached as Appendix B to this Proxy Statement/Prospectus and is incorporated herein by reference.

VSB Bancorp shareholders are urged to read the opinion in its entirety for a description of the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by FinPro.

FinPro’s opinion speaks only as of the date of such opinion. FinPro’s opinion addresses only the fairness, from a financial point of view, of the consideration offered in the Merger. It does not address the underlying business decision to proceed with the Merger and does not constitute a recommendation to any

VSB Bancorp shareholder as to how the shareholder should vote at the VSB Bancorp special meeting on the Merger Agreement or any related matter. FinPro was not retained to structure, analyze, negotiate or perform any services related to this merger outside of the scope of rending a fairness opinion.

In rendering its opinion, FinPro considered among other things:

| • | A draft of the merger agreement dated December 16, 2019 (the most current draft available to FinPro);

| • | The most recent year-end audited and quarter-end public filings for each of VSB Bancorp and Northfield Bancorp;

| • | Certain other public and non-public information regarding each of VSB Bancorp and Northfield Bancorp, including internal financial forecasts, regarding the financial results and the condition of VSB Bancorp and Northfield Bancorp;

| • | Acquisition multiples of comparable institutions;

| • | The potential investment value of VSB Bancorp’s shares;

| • | The trading and merger market for bank and thrift stocks;

| • | The relative contribution of each entity to the pro forma combined institution;

| • | The ability of Northfield Bancorp to execute on the proposed transaction; and

| • | The pro forma financial impact of the transaction.

In performing its review and in rendering its opinion, FinPro has relied upon the completeness and accuracy of all of the financial and other information that was available to it from public sources, that was provided to it by VSB Bancorp and Northfield Bancorp, or their representatives, or that was otherwise reviewed by FinPro, and has assumed such completeness and accuracy for purposes of rendering its opinion. FinPro has further relied on the assurances of management of VSB Bancorp that they are not aware of any facts or circumstances not within the actual knowledge of FinPro that would make any of such information inaccurate or misleading. FinPro has not been asked to verify and has not undertaken any independent verification of such information, and FinPro does not assume any responsibility or liability for the completeness and accuracy thereof. FinPro did not conduct due diligence on VSB Bancorp or Northfield Bancorp. FinPro has not made an independent evaluation or appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of VSB Bancorp, Northfield Bancorp, or any subsidiaries, or the collectability of any such assets, nor has FinPro been furnished with any such evaluations or appraisals. FinPro has not made any independent evaluation of the adequacy of the allowance for loan losses of VSB Bancorp or Northfield Bancorp, nor has FinPro reviewed any individual credit files, and FinPro has assumed that the respective allowance for loan losses for each of VSB Bancorp and Northfield Bancorp is adequate.

FinPro also assumed, with VSB Bancorp’s consent, that (i) each of the parties to the Merger Agreement would comply in all material respects with all material terms of the Merger Agreement, that all of the representations and warranties contained in the Merger Agreement were true and correct in all material respects, that each of the parties to the Merger Agreement would perform in all material respects all of the covenants required to be performed by such party under the Merger Agreement and that the conditions precedent in the Merger Agreement would not be waived, (ii) in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the merger, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on VSB Bancorp, Northfield Bancorp or the merger in any respect that would be material to FinPro’s analyses, (iii) the merger and any related transaction would be consummated in accordance with the terms of the Merger Agreement without any waiver, modification or amendment of any material term, condition or agreement thereof and in compliance with all applicable laws and other requirements, and (iv) the merger would qualify as a tax-free reorganization for federal income tax purposes. FinPro expressed no opinion as to any of the legal, accounting or tax matters relating to the merger or any other transactions contemplated in connection therewith.

FinPro’s analyses and the views expressed in its opinion were necessarily based on financial, economic, regulatory, market and other conditions as in effect on, and the information made available to FinPro as of, the date of its opinion. Events occurring after the date of the opinion could materially affect FinPro’s views. FinPro has not undertaken to update, revise, reaffirm or withdraw its opinion or otherwise comment upon events

occurring after the date of its opinion. FinPro expressed no opinion as to the trading values of VSB Bancorp common stock after the date of its opinion or what the value of Northfield Bancorp common stock will be once it is actually received by the holders of VSB Bancorp common stock.

The following is a summary of the material analyses performed by FinPro and presented to the VSB Bancorp board of directors on December 20, 2019. The summary is not a complete description of all the analyses underlying FinPro’s opinions. The preparation of a fairness opinion is a complex process involving subjective judgments as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. Therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. FinPro believes that its analyses must be considered as a whole and that selecting portions of the factors and analyses considered, without considering all factors and analyses, or attempting to ascribe relative weights to some or all such factors and analyses, could create an incomplete view of the evaluation process underlying its opinion. The financial analyses summarized below include information presented in a tabular format. In order to understand fully the financial analyses, these tables must be read together with the accompanying text. The tables alone do not constitute a complete description of the financial analyses.

No company included in FinPro’s comparative analyses described below is identical to VSB Bancorp or Northfield Bancorp and no transaction is identical to the merger. An analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values or merger transaction values, as the case may be, of VSB Bancorp and Northfield Bancorp and the companies to which they are being compared. In arriving at its opinion, FinPro did not attribute any particular weight to any analysis or factor that it considered. Rather, FinPro made qualitative judgments as to the significance and relevance of each analysis and factor. FinPro did not form an opinion as to whether any individual analysis or factor (positive or negative) considered in isolation supported or failed to support its opinion, rather, FinPro made its determination as to the fairness of the merger consideration on the basis of its experience and professional judgment after considering the results of all its analyses taken as a whole.

In performing its analyses, FinPro also made numerous assumptions with respect to industry performance, business and economic conditions and various other matters, many of which cannot be predicted and are beyond the control of VSB Bancorp, Northfield Bancorp and FinPro. The analyses performed by FinPro are not necessarily indicative of actual values or future results, both of which may be significantly more or less favorable than suggested by such analyses. FinPro prepared its analyses solely for purposes of rendering its opinion and provided such analyses to the VSB Bancorp board of directors at its December 20, 2019 meeting. Estimates on the values of companies do not purport to be appraisals or necessarily reflect the prices at which companies or their securities may actually be sold. Such estimates are inherently subject to uncertainty and actual values may be materially different. Accordingly, FinPro’s analyses do not necessarily reflect the value of VSB Bancorp common stock or the prices at which VSB Bancorp or Northfield Bancorp common stock may be sold at any time. The analyses of FinPro and its opinion were among a number of factors taken into consideration by the VSB Bancorp board of directors in making its determination to approve the Merger Agreement and the analyses described below should not be viewed as determinative of the decision of the VSB Bancorp board of directors or management with respect to the fairness, from a financial point of view, of the merger consideration to VSB Bancorp shareholders.

Market Value Approach (Acquisition Comparables). FinPro reviewed publicly available information related to selected whole bank transactions in VSB Bancorp’s geographic region. The financial performance metrics of the acquired companies were compared to VSB Bancorp’s most recent publicly available financials. Multiples for the Northfield Bancorp/VSB Bancorp transactions were analyzed relative to a comparable transaction group selected by FinPro. A regional comparable acquisition group was used for the market value approach. FinPro considered the following pricing multiples:

| • | Price/Tangible Book Value: price per common share paid for the acquired company to tangible book value per share of the acquired company based on the latest publicly available financial statements of the company available prior to the announcement of the acquisition;

37

TABLE OF CONTENTS

| • | Price/LTM (last twelve months) Earnings: price per common share paid for the acquired company to last twelve months earnings per share of the acquired company based on the latest publicly available financial statements of the company available prior to the announcement of the acquisition;

| • | Core Deposit Premium: excess of purchase price over tangible common equity to core deposits (total deposits less time deposits greater than $100,000) based on the latest publicly available financial statements of the company available prior to the announcement of the acquisition.

Comparable Regional Group. For the primary group in the market value approach, FinPro used the following criteria to determine the Comparable Regional Group: Whole bank transactions announced after January 1, 2019, where the acquired company was headquartered in the Mid-Atlantic and Northeast regions, where the acquired company had total assets between $100 million and $700 million, and NPAs (including TDRs)/Total Assets were less than 2.5%. Transactions where the acquired company was structured as a mutual or MHC and transactions for which price to tangible book data was unavailable were excluded.

The selected transactions were:

The merger consideration price to tangible book multiple of 161.5% was nearly in line with the median for the regional comparable group, price to LTM earnings of 16.3x was below the median but above the 25th percentile for the regional comparable group and the core deposit premium of 9.5% was above the median for the regional comparable group.

Investment Value Approach (Discounted Cash Flow). FinPro performed a discounted cash flow (“DCF”) analysis to estimate a range of the present values of free cash flows, inclusive of projected cash dividends to shareholders and net income held in retained earnings that VSB Bancorp could generate on a stand-alone basis. The purpose of this analysis was to determine the range of present values of a potential VSB Bancorp liquidity event at September 30, 2024. The DCF analysis does not include any synergies or cost savings in the analysis as it is an analysis of VSB Bancorp operating independently from September 30, 2019 through September 30, 2024 and then a projected sale of VSB Bancorp at that time. The DCF analysis is a widely used valuation methodology that relies on numerous assumptions, including VSB Bancorp’s financial projections as provided by

VSB Bancorp’s management, terminal values, and discount rates. In performing this analysis, FinPro utilized projections provided and verified by VSB Bancorp management through September 30, 2024. VSB Bancorp is projected to pay cash dividends to shareholders in the projections. The projections utilized for the investment value approach are shown below.

FinPro utilized a discount rate based on a Capital Asset Pricing Model (“CAPM”) approach. The CAPM model utilized the Duff & Phelps long-term risk-free rate, the decile 10 size premium, and the beta based on the 3-Year SNL Microcap U.S. Bank Index benchmarked against the S&P 500 as of December 18, 2019. This resulted in a base discount rate of 9.4%. A range of discount rates were utilized that were 2% and 1% below the base rate and 1% and 2% above the base rate, resulting in discount rates that ranged from 7.4% to 11.4%. In calculating the terminal value, FinPro utilized between 159.5% and 179.5% for a P/TBVS (price to tangible book value) approach and multiples between 14.2 times and 18.2 times for a P/E (price to earnings) approach. The midpoint of the P/TBVS multiple range is the median (year-to-date through December 18, 2019) P/TBVS multiple for nationwide bank and thrift transactions with total deal value between $50 million and $100 million. The midpoint of the P/E multiple range is the median (year-to-date through December 18, 2019) P/E multiple for nationwide bank and thrift transactions with total deal value between $50 million and $100 million. The sensitivity analysis range provides for values both above and below this midpoint. This resulted in a range of present values from $26.35 to $34.97 on a tangible book value basis and $18.43 to $27.28 per share on an earnings basis. The merger consideration that FinPro evaluated in issuing the fairness opinion was $33.26 per share. All but three of the 25 present values calculated on a tangible book value basis were below the consideration price and all 25 of the values on an earnings basis were below the consideration price.

Pro Forma Analysis. FinPro considered and reviewed the pro forma financial impact of the transaction to ensure that Northfield Bancorp, post-transaction, has key ratios for the combined entity that are likely to be acceptable from a regulatory perspective. FinPro analyzed certain potential pro forma effects of the merger, based on the following assumptions: (i) the merger closes during the second quarter of 2020; (ii) 100% of the outstanding shares of VSB Bancorp common stock are converted into the stock consideration at a 1.9553 exchange ratio; and (iii) all outstanding VSB Bancorp stock options with an exercise price less than $33.26 will be cancelled in exchange for a cash payment equal to the difference between $33.26 and the per share exercise price. FinPro also utilized the following: (a) estimated earnings per share for Northfield Bancorp; (b) estimated earnings per share for VSB Bancorp; (c) purchase accounting adjustments consisting of (x) a credit mark on loans, (y) interest rate marks on investments, loans, certificates of deposit and borrowings and (z) Current Expected Credit Losses (“CECL”) adjustment; (d) cost savings projections provided by Northfield Bancorp; (e) estimated costs and expenses associated with the merger; and (f) a core deposit intangible asset amortized

over ten years utilizing sum-of-the-digits methodology. The analysis indicated that the merger should be accretive to Northfield Bancorp’s estimated earnings per share (excluding one-time transaction costs and expenses) after closing and modestly dilutive to estimated tangible book value per share at closing of the transaction with a workback period of approximately four years.

Pro Forma Contribution Analysis. FinPro considered and reviewed the pro forma financial impact of the transaction to ensure that Northfield Bancorp post-transaction has key ratios for the combined entity that are likely to be acceptable from a regulatory perspective. FinPro also analyzed the potential future benefit to VSB Bancorp shareholders and the relative contribution analysis of assets, gross loans, nonmaturity core deposits, tangible common equity and net income based upon pro forma financial analysis as of the closing of the transaction. Based upon the exchange ratio, Northfield Bancorp stockholders would own approximately 93% of the pro forma company and VSB Bancorp shareholders would own approximately 7% of the pro forma company.

Miscellaneous. FinPro provided a fairness opinion to VSB Bancorp associated with the proposed merger and did not act as an advisor to or agent of any other person. FinPro was not retained to structure, analyze, negotiate or perform any services related to this merger outside of the scope of rendering a fairness opinion.

FinPro was compensated $125,000 for its providing a fairness opinion. Additionally, VSB Bancorp has agreed to reimburse FinPro for its out-of-pocket expenses and has agreed to indemnify FinPro and certain related persons against certain liabilities possibly incurred in connection with the services performed.

FinPro, Inc. (“FPI”), FinPro’s parent organization, has provided consulting services to VSB Bancorp within the past two years. The amount of compensation received from VSB Bancorp for these services is not, and has not been, material to FPI’s annual gross revenue. FPI has not provided services to Northfield Bancorp within the past two years other than Northfield Bancorp’s annual subscription to FPI’s annual global webinar package. Prior to this current fairness opinion engagement with VSB Bancorp, FinPro has not been compensated for investment banking services to VSB Bancorp or Northfield Bancorp in the past two years. No material relationship exists between FinPro or FPI, and all parties to the transaction.

Consideration to be Received in the Merger

Under the terms of the Merger Agreement, each outstanding share of VSB Bancorp common stock will be converted into the right to receive between 1.8514 shares of Northfield Bancorp common stock and 2.0463 shares of Northfield Bancorp common stock, as determined by dividing (rounded to the fourth decimal place) $33.30 by Northfield Bancorp’s average stock price for a ten-day period ending on the fifth business day prior to the closing of the merger. However, if the average stock price is greater than $17.99, then the exchange ratio will be 1.8514, and if the average stock price is less than $16.27, then the exchange ratio will be 2.0463. Based on an average price of $17.13, which was the ten-day average closing stock price of Northfield Bancorp common stock as of December 20, 2019, which was the last trading date preceding the public announcement of the proposed merger, the merger consideration would have been 1.9440 shares of Northfield Bancorp common stock for each share of VSB Bancorp common stock. As of , the most reasonably practicable date before the mailing of this Proxy Statement/Prospectus, Northfield Bancorp’s ten-day average closing stock price common stock common stock price was $ , the merger consideration would have been shares of Northfield Bancorp common stock for each share of VSB Bancorp common stock.

TABLE OF CONTENTS

If Northfield Bancorp effects or sets a record date for a stock split, stock dividend, recapitalization, reclassification or similar transaction with respect to its shares of common stock that is before the effective time of the Merger, then the exchange ratio will be adjusted proportionately.

VSB Bancorp shareholders will not receive fractional shares of Northfield Bancorp common stock. Instead, VSB Bancorp shareholders will receive a cash payment for any fractional shares equal to the product of (1) the fraction of a share of Northfield Bancorp common stock to which such shareholder is entitled multiplied by (2) the average closing price of Northfield Bancorp common stock during the ten consecutive trading days ending three trading days preceding the closing date of the Merger.

Treatment of VSB Bancorp, Inc. Stock Options

At the effective time of the Merger, each outstanding option to purchase shares of VSB Bancorp common stock will cease to represent an option to purchase VSB Bancorp common stock and will be converted automatically into the right to receive cash equal to the difference between the value of the Northfield Bancorp common stock to be received as merger consideration and the exercise price per share of such VSB Bancorp stock option multiplied by the number of shares subject to such VSB Bancorp stock option.

Surrender of Stock Certificates

VSB Bancorp shareholders will receive instructions from the transfer agent on where to surrender their VSB Bancorp stock certificates after the Merger is completed. VSB Bancorp shareholders should not forward their VSB Bancorp stock certificates with their proxy cards.

Accounting Treatment of the Merger

In accordance with current accounting guidance, the Merger will be accounted for using the acquisition method. The result of this is that the recorded assets and liabilities of Northfield Bancorp will be carried forward at their recorded amounts, the historical operating results will be unchanged for the prior periods being reported on and the assets and liabilities of VSB Bancorp will be adjusted to fair value at the date of the Merger. In addition, all identified intangible assets will be recorded at fair value and included as part of the net assets acquired. To the extent that the purchase price, consisting of shares of Northfield Bancorp common stock to be issued to VSB Bancorp shareholders and the cash payment to option holders, exceeds the fair value of the net assets including identifiable intangibles of VSB Bancorp at the Merger date, that amount will be reported as goodwill. In accordance with current accounting guidance, goodwill will not be amortized but will be evaluated for impairment annually. Identified intangibles will be amortized over their estimated lives. Further, the acquisition method of accounting results in the operating results of VSB Bancorp being included in the operating results of Northfield Bancorp beginning from the date of completion of the Merger.

Material U.S. Federal Income Tax Consequences of the Merger

General. The following summary discusses the material anticipated U.S. federal income tax consequences of the Merger applicable to a U.S. holder (as defined below) of shares of VSB Bancorp common stock. This discussion is based upon the Internal Revenue Code, Treasury Regulations, judicial authorities, published positions of the Internal Revenue Service (which we refer to as the “IRS”), and other applicable authorities, all as in effect on the date of this document and all of which are subject to change or to differing interpretations (possibly with retroactive effect). For purposes of this discussion, the term “U.S. holder” means a beneficial owner of VSB Bancorp common stock that is for U.S. federal income tax purposes: (a) an individual citizen or resident of the United States; (b) a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) organized in or under the laws of the United States or any state thereof or the District of Columbia; (c) a trust if (1) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) such trust has made a valid election to be treated as a U.S. person for U.S. federal income tax purposes; or (d) an estate, the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source. This discussion is limited to U.S. holders who hold their shares as capital assets for U.S. federal income tax purposes within the meaning of Section 1221 of the Internal Revenue Code. This discussion does not cover all U.S. federal income tax consequences of the Merger and related transactions that may be relevant to holders of shares of VSB Bancorp common stock. This discussion also does not address

45

TABLE OF CONTENTS

all of the tax consequences that may be relevant to a particular person or the tax consequences that may be relevant to persons subject to special treatment under U.S. federal income tax laws (including, among others, tax-exempt organizations, dealers in securities or foreign currencies, banks, insurance companies, financial institutions, regulated investment companies, persons who hold their shares of VSB Bancorp common stock as part of a hedge, straddle, constructive sale or conversion transaction, persons whose functional currency is not the U.S. dollar, persons that are, or hold their shares of VSB Bancorp common stock through, partnerships or other pass-through entities, retirement plans or other tax-deferred accounts, or persons who acquired their shares of VSB Bancorp common stock through the exercise of an employee stock option or otherwise as compensation). In addition, this discussion does not address any aspects of state, local, non-U.S. taxation or U.S. federal taxation other than income taxation. No ruling has been requested from the IRS regarding the U.S. federal income tax consequences of the Merger. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of the U.S. federal income tax consequences set forth below.

Determining the actual tax consequences of the Merger to a U.S. holder is complex and can depend, in part, on the U.S. holder’s specific situation. VSB Bancorp shareholders are urged to consult their tax advisors as to the U.S. federal income tax consequences of the Merger, as well as the effects of state, local, non-U.S. tax laws and U.S. tax laws other than income tax laws.

Opinion. It is a condition to the obligations of Northfield Bancorp and VSB Bancorp that each receive an opinion of counsel to the effect that the Merger will constitute a “reorganization” for U.S. federal income tax purposes within the meaning of Section 368(a) of the Internal Revenue Code. Northfield Bancorp and VSB Bancorp both expect to be able to obtain the tax opinions if, as expected:

| • | each of Northfield Bancorp and VSB Bancorp is able to deliver customary representations to their respective tax counsel; and

| • | there is no adverse change in U.S. federal income tax law.

In connection with the filing of the registration statement of which this Proxy Statement/Prospectus forms a part, Luse Gorman, PC, counsel to Northfield Bancorp, has delivered its opinion to Northfield Bancorp, and Gallet Dreyer & Berkey, LLP, counsel to VSB Bancorp, has delivered its opinion to VSB Bancorp, that the Merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code. The discussion below of the material U.S. federal income tax consequences of the Merger serves, insofar as such discussion constitutes statements of United States federal income tax law or legal conclusions, as the opinion of each of Luse Gorman, PC and Gallet Dreyer & Berkey, LLP as to the material U.S. federal income tax consequences of the Merger to the U.S. holders of VSB Bancorp common stock. These opinions have been rendered on the basis of facts, representations and assumptions set forth or referred to in each opinion and factual representations contained in certificates of officers of Northfield Bancorp and VSB Bancorp. The opinions of each party’s tax counsel are not binding on the IRS or any court, and must continue to be true and accurate in all material respects as of the effective time of the Merger.

If any of the representations delivered by Northfield Bancorp or VSB Bancorp to counsel or assumptions upon which the opinions are based are inconsistent with the actual facts, the tax consequences of the Merger could be adversely affected. The determination by tax counsel as to whether the proposed Merger will be treated as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code will depend upon the facts and law existing at the effective time of the proposed Merger.

Exchange for Northfield Bancorp Common Stock. No gain or loss will be recognized by a VSB Bancorp shareholder for the shares of Northfield Bancorp common stock received (except for cash received in lieu of a fractional share, as discussed below) in exchange for his or her shares of VSB Bancorp common stock. The tax basis of the shares of Northfield Bancorp common stock received by a VSB Bancorp shareholder in the exchange will be equal (except for the basis attributable to any fractional share of Northfield Bancorp common stock, as discussed below) to the basis of the VSB Bancorp common stock surrendered in exchange for the Northfield Bancorp common stock. The holding period of the Northfield Bancorp common stock received will include the holding period of shares of VSB Bancorp common stock surrendered in exchange for the Northfield Bancorp common stock, provided that the shares were held as capital assets of the VSB Bancorp shareholder at the effective time of the Merger.

46

TABLE OF CONTENTS

Cash in Lieu of Fractional Shares. A VSB Bancorp shareholder who receives cash in lieu of a fractional share interest in Northfield Bancorp common stock will be treated as having received the fractional share of Northfield Bancorp common stock and then as having sold the fractional share for cash in full payment for such fractional share of stock. As a result, a VSB Bancorp shareholder will generally recognize a gain or loss, for federal income tax purposes, equal to the difference between the cash received and such portion of a shareholder’s tax basis in the VSB Bancorp common stock surrendered in exchange for the cash. Such gain or loss will be a capital gain or loss, provided that such shares were held as capital assets of the VSB Bancorp shareholder at the effective time of the Merger. Such gain or loss will be long-term capital gain or loss if the VSB Bancorp shareholder’s holding period is more than one year at the effective time of the Merger. The Internal Revenue Code contains limitations on the extent to which a taxpayer may deduct capital losses from ordinary income.

Backup Withholding. Unless an exemption applies under the backup withholding rules of the Internal Revenue Code, the exchange agent shall be required to withhold, and will withhold, 24% of any cash payments to which a VSB Bancorp shareholder is entitled pursuant to the Merger, unless the VSB Bancorp shareholder signs the substitute IRS Form W-9 enclosed with the letter of transmittal sent by the exchange agent. Unless an applicable exemption exists and is proved in a manner satisfactory to the exchange agent, this completed form provides the information, including the VSB Bancorp shareholder’s taxpayer identification number, and certification necessary to avoid backup withholding.

Reporting Requirements. A VSB Bancorp shareholder who receives Northfield Bancorp common stock pursuant to the Merger will be required to retain records pertaining to the Merger, and any such holder who, immediately before the Merger, holds at least 1% (by vote or value) of the outstanding VSB Bancorp stock, or securities of VSB Bancorp with a basis for U.S. federal income tax purposes of at least $1.0 million, will be required to file with its federal income tax return for the year in which the Merger takes place a statement setting forth certain facts relating to the Merger. U.S. holders are urged to consult with their tax advisors with respect to these and other reporting requirements applicable to the Merger. Any amounts withheld under the backup withholding rules are not an additional tax and will generally be allowed as a refund or credit against the U.S. holder’s U.S. federal income tax liability, provided the U.S. holder timely furnishes the required information to the IRS.

Tax Treatment of the Entities. No gain or loss will be recognized by Northfield Bancorp or VSB Bancorp as a result of the Merger.

Regulatory Matters Relating to the Merger

Completion of the Merger is subject to the receipt of all required approvals and consents from regulatory authorities. The Merger is subject to approval by the OCC, the NYSDFS and the Federal Reserve. Northfield Bancorp has filed the required applications and notifications.

Bank Merger. The bank merger is subject to the approval of the OCC under the Bank Merger Act. In granting its approval under the Bank Merger Act, the OCC must consider the financial and managerial resources and future prospects of the existing and resulting institutions, the convenience and needs of the communities to be served, competitive factors, any risk to the stability of the United States banking or financial system and the effectiveness of the institutions involved in combating money laundering activities.

Holding Company Merger. The merger of VSB Bancorp with and into Northfield Bancorp, with Northfield Bancorp as the surviving savings and loan holding company, requires the approval, non-objection or waiver of the Federal Reserve, and the approval of the NYSDFS under applicable New York law. The Federal Reserve will consider factors such as financial and managerial resources, future prospects, the convenience and needs of the community and competitive factors. The NYSDFS follows criteria similar to those used by the Federal Reserve.

Anti-Competitive Matters. In addition, a period of 15 to 30 days must expire following approval by the OCC before completion of the Merger is allowed, within which period the United States Department of Justice may file objections to the Merger under the federal antitrust laws. While Northfield Bancorp and VSB Bancorp believe that the likelihood of objection to the Merger by the Department of Justice is remote, there can be no assurance that the Department of Justice will not initiate proceedings to block the Merger, or that the Attorney General of the State of New York will not challenge the Merger, or if any proceeding is instituted or challenge is made, what the result of such challenge or proceeding would be.

47

TABLE OF CONTENTS

The Merger cannot proceed in the absence of the requisite regulatory approvals. See “—Conditions to Completing the Merger” and “—Terminating the Merger Agreement.” There can be no assurance that the requisite regulatory approvals will be obtained, and if obtained, there can be no assurance as to the date of any approval. There also can be no assurance that any regulatory approvals will not contain a condition or requirement that causes the approvals to fail to satisfy one or more conditions set forth in the Merger Agreement and described under “—Conditions to Completing the Merger.”

The approval of any application merely implies the satisfaction of regulatory criteria for approval, which does not include, for example, review of the Merger from the standpoint of the adequacy of the merger consideration. Furthermore, regulatory approvals do not constitute an endorsement or recommendation with respect to the Merger.

Interests of Certain Persons in the Merger that are Different from Yours

In considering the recommendation of the board of directors of VSB Bancorp that you vote to adopt the Merger Agreement, you should be aware that some of VSB Bancorp’s officers and directors have employment and other compensation agreements or economic interests in the Merger that are different from, or in addition to, your interests as VSB Bancorp shareholders generally. The VSB Bancorp board of directors was aware of and considered these interests, among other matters, in evaluating and negotiating the Merger Agreement, and in recommending to the shareholders that the Merger Agreement and the Merger be adopted.

Share Ownership. On the record date for the VSB Bancorp special meeting, VSB Bancorp’s directors and officers beneficially owned, in the aggregate, [insider shares] shares of VSB Bancorp’s common stock (not including shares that may be acquired upon the exercise of stock options), representing approximately [insider ownership]% of the outstanding shares of VSB Bancorp common stock.

Stock Options. Under the terms of the Merger Agreement, each outstanding option to purchase shares of VSB Bancorp common stock will be exchanged for an amount of cash, referred to as the “option consideration” which is equal to the amount by which (i) the product of (x) the average daily closing sales price of Northfield Bancorp common stock for the 10 consecutive trading days ending on and including the fifth business day preceding the closing date and (y) the exchange ratio, exceeds (ii) the per share exercise price of such VSB Bancorp stock option, multiplied by the number of shares subject to such VSB Bancorp stock option. If the exercise price of a VSB Bancorp option is greater than or equal to the option consideration, then the VSB Bancorp option will be canceled without any payment to the option holder. The number of VSB Bancorp stock options with such a positive difference held by the executive officers and the non-employee directors of VSB Bancorp as a group as of the record date for the special meeting is as follows:

Executive/Director of VSB Bancorp | VSB Bancorp Stock Options (#) | Weighted-Average Exercise Price ($)
Raffaele Branca |  | 12,312 |  |  | 16.21 |
All non-employee directors as a group (6) persons)(1) |  | 36,948 |  |  | 14.85 |

| (1) | The following non-employee directors hold stock options as of the record date: Ms. Nerlino Caddell, 6,885 shares; Judge Gigante, 1,185 shares; Mr. Johnsen, 8,135 shares; Mr. LiBassi, 8,138 shares; Mr. Moore, 1,885 shares; Dr. Perez, 8,135 shares and Mr. Savo, 1,885 shares.

If during the period beginning upon the public announcement of an intended change in control (as defined in the agreement) and ending six months after a change in control is consummated, Mr. Branca’s employment is terminated for any reason other than death, or if he terminates his employment for any reason during such period, he will be entitled to (a) his earned but unpaid salary through the date of termination; (b) the benefits to which he and his family would be entitled under the employee benefit and compensation plans of the Bank as in effect 60 days prior to the change in control; (c) continued group life, health and disability insurance benefits as if he had continued his employment for three years after the change in control; and (d) a lump sum payment

equal to 2.99 times his then-current base salary plus his most recent cash incentive bonus (excluding any stock-based compensation), but in no event more than the lesser of (i) $1,200,000 or (ii) the maximum amount permitted under Code Section 280G without the imposition of an excise tax or penalties.

Offer of Employment to Raffaele M. Branca. In connection with the Merger, Northfield Bank has offered employment to Mr. Branca as Northfield Bank’s Senior Vice President, Market Area President – Staten Island Region. If Mr. Branca accepts the offer, Northfield Bank will pay him an annual base salary of $250,000. In addition, Northfield Bank will pay Mr. Branca a one-time cash bonus of $200,000, payable on or about one year from Mr. Branca’s initial employment date. If Mr. Branca is terminated without cause or resigns for good reason during this period, he would be entitled to the cash bonus but would not be entitled to the cash bonus if Mr. Branca terminates without good reason. Mr. Branca would be entitled to participate in the Northfield Bancorp 2019 Equity Incentive Plan and would receive equity grants subject to the discretion of the Compensation Committee. Commencing in 2021, Mr. Branca also will be entitled to participate in Northfield Bank’s annual cash incentive plan, with a bonus targeted at 25% of his base salary contingent upon achieving established goals. He would also receive either a monthly automobile allowance of $675, subject to tax deductions and withholding or reimbursement of normal business-related automobile expenses. In addition to the above, he would be entitled to participate in customary Northfield Bank medical, life, disability plans and would be eligible for Northfield Bank’s tax-qualified 401(k) plan and employee stock ownership plan. In the event Mr. Branca accepts employment with Northfield Bank, his existing employment agreement will be terminated in consideration of a payment of $1,200,000.

Consulting Agreement with Joseph J. LiBassi, Chairman of the Board of VSB Bancorp and Victory State Bank. Contemporaneously with the execution of the Merger Agreement, Northfield Bancorp and Northfield Bank (collectively, “Northfield”) entered into a consulting agreement with Mr. Joseph J. LiBassi. The consulting agreement is effective immediately upon consummation of the merger and will expire at the end of three years from the effective date. Under the consulting agreement, Mr. LiBassi will provide services as an independent contractor to Northfield, as and when Northfield may request, which services may be provided with respect to all phases of Northfield’s business and particularly those phases in which LiBassi has particular expertise and knowledge, including matters related to Victory’s customers and operations. The consulting services will be provided for up to a maximum of 25 hours per month, not to exceed 900 hours during the term of the consulting agreement. In consideration of the consulting services, Northfield will pay $10,000 per month to Mr. LiBassi over a period of 36 months, or $360,000 in the aggregate. Under the consulting agreement, Mr. LiBassi agrees to preserve the confidential information of VSB Bancorp, Victory State Bank and Northfield, including proprietary information, customer information and employee information, as each is defined in the consulting agreement. In addition, Mr. LiBassi agrees not to compete with Northfield during the term of the consulting agreement in the geographic area of Staten Island, New York.

Accelerated Vesting of Post-Retirement Death Benefit under Split Dollar Life Insurance Plan. Victory State Bank maintains a split dollar insurance plan covering certain officers and employees, including Mr. Branca. Under the split dollar plan, on a participant’s death while employed, the participant’s beneficiaries will receive from 2.5 to three times the participant’s base salary upon his death. In the event a participant terminates employment on or after age 65, the participant will have a lifetime death benefit of $50,000. In the event of a change in control, the post-retirement death benefit will vest in a participant without regard to the participant’s age. There are eight participants in the split dollar plan. Seven of the participants, including Mr. Branca, will not have attained age 65 at the time of the change in control and will vest in the post-retirement death benefit as a result of the change in control.

Advisory Board. In accordance with the Merger Agreement, Northfield Bank will establish an advisory board consisting of each of the VSB Bancorp directors (excluding VSB Bancorp’s Chairman of the Board, and excluding VSB Bancorp’s President and Chief Executive Officer if he accepts employment with Northfield Bank or if his participation in the advisory board presents a conflict of interest under applicable law, regulation or existing bank policies or criteria). The function of the advisory board will be to advise Northfield Bank with respect to deposit and lending activities in Victory State Bank’s former market area and to maintain and develop customer relationships. Northfield Bank intends to maintain the advisory board for a period of at least two years. Each member of the advisory board will receive $3,000 per advisory board meeting attended, typically with four meetings scheduled per year.

TABLE OF CONTENTS

Indemnification. Pursuant to the Merger Agreement, Northfield Bancorp has agreed that, for a period of six years after the effective time of the Merger, it will indemnify, defend and hold harmless each present and former officer, director or employee of VSB Bancorp and its subsidiaries, including any individual who becomes an officer, director or employee of VSB Bancorp or its subsidiaries before the closing of the Merger, against all losses, claims, damages, costs, expenses (including attorneys’ fees), liabilities or judgments or amounts that are paid in settlement of or in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal or administrative, based in whole or in part or arising in whole or in part out of the fact that such person is or was a director, officer or employee of VSB Bancorp or any of its subsidiaries if such claim pertains to any matter of fact arising, existing or occurring before the effective time of the Merger (including, without limitation, the Merger and other transactions contemplated by the Merger Agreement), to the fullest extent as would have been permitted by VSB Bancorp under the New York Business Corporation law and under VSB Bancorp’s certificate of incorporation and bylaws, to the extent not prohibited by applicable law.

Directors’ and Officers’ Insurance. Northfield Bancorp has further agreed, for a period of six years after the effective time of the Merger, to maintain, or to cause Northfield Bank to maintain, the current directors’ and officers’ liability insurance policies of VSB Bancorp (provided, that Northfield Bancorp may substitute policies of at least the same coverage containing terms and conditions that are not materially less favorable) with respect to matters occurring before the effective time of the Merger. Northfield Bancorp is not required to spend, in the aggregate, more than 200% of the annual premiums currently paid by VSB Bancorp for its insurance coverage, and if the amount necessary to maintain such insurance coverage exceeds 200% of such current annual premiums, Northfield Bancorp will provide the most advantageous insurance policies obtainable for such amount.

Employee Matters

Northfield Bancorp will review all compensation and benefit plans of VSB Bancorp and its subsidiaries to determine whether to maintain, consolidate terminate or continue such plans. If Northfield Bancorp freezes or terminates any such compensation and benefit plan, a continuing employee will be eligible to participate in any similar Northfield Bancorp employee plan, to the extent that one exists (other than any non-qualified deferred compensation plan, employment agreement, change in control agreement, supplemental executive arrangement or equity incentive plan or other similar type of arrangement). Employees of VSB Bancorp who become participants in any Northfield Bancorp compensation and benefit plan will be given credit for service as an employee of VSB Bancorp before the closing of the Merger for determining eligibility and vesting requirements (but not for benefit accrual purposes, except that credit for benefit accrual purposes will be given in the Northfield Bank Employee Savings Plan or any vacation or paid time off plan), and except that credit for prior service will be given under the Northfield Bank Employee Stock Ownership Plan only to determine eligibility to participate in that plan and not for vesting purposes, and credit for prior service will not be given under the Northfield Bank retiree health plan. In the event of the termination of a VSB Bancorp health plan or consolidation of such plan with a Northfield Bancorp or Northfield Bank health plan, Northfield Bancorp will make available to continuing employees and their eligible dependents employer-provided health care coverage on the same basis as it provides such coverage to Northfield Bancorp employees. Northfield Bancorp will use commercially reasonable efforts to waive limitations as to preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements under Northfield Bancorp’s health and welfare plans for such continuing employees.

Any employee of VSB Bancorp, other than an employee who is a party to an employment agreement, change in control agreement or other separation agreement that provides a benefit on a termination of employment, whose employment is terminated involuntarily (other than for cause) within nine months following the completion of the Merger, will receive a lump sum severance payment in accordance with the VSB Bancorp severance plan, provided that such employee enters into a release of claims in a form satisfactory to Northfield Bancorp. The plan provides different levels of severance based on the individual’s title and years of service. An employee at the assistant vice president level and below is entitled to two weeks of salary for each full year of service, up to 26 weeks of salary. A vice president or above with less than five years of service is entitled to a severance benefit equal to 26 weeks of salary and with more than five years of service is entitled to a severance benefit of one year of salary. A senior vice president with more than five years of service is entitled to a severance benefit equal to two year of base salary. Mr. Branca is the only employee of VSB Bancorp who is party to an agreement that provides a benefit on a termination of employment.

Pursuant to the terms of the Merger Agreement, if requested by Northfield Bancorp, VSB Bancorp will terminate the VSB Bancorp 401(k) Plan immediately prior to the effective time of the Merger. If the 401(k) Plan

50

TABLE OF CONTENTS

is terminated, VSB Bancorp or Northfield Bank will seek a favorable determination letter from the IRS on the tax-qualified status of the 401(k) Plan on termination. As soon as administratively practicable following the receipt of a favorable determination letter from the IRS, the account balances of all participants and beneficiaries in the plan will either be distributed or transferred to an eligible tax-qualified retirement plan or individual retirement account, as directed by the participant or beneficiary.

VSB Bancorp will terminate the VSB Bancorp Employee Stock Ownership Plan immediately prior to the effective time of the Merger. VSB Bancorp will continue to accrue and make contributions to the Employee Stock Ownership Plan for the plan year ending as of the Employee Stock Ownership Plan termination date consistent with its current loan amortization schedule. No later than the effective time of the Merger, a sufficient number of unallocated shares of VSB Bancorp common stock held as collateral by the VSB Bancorp Employee Stock Ownership Plan will be used to repay the outstanding share acquisition loan. Any remaining unallocated shares in the VSB Bancorp Employee Stock Ownership Plan after repayment of the share acquisition loan will be allocated to the accounts of plan participants in accordance with the plan documents. VSB Bancorp will seek a favorable determination letter from the IRS on the tax-qualified status of the VSB Bancorp Employee Stock Ownership Plan on termination. As soon as administratively practicable following the receipt of a favorable determination letter from the IRS, the account balances of all participants and beneficiaries in the plan will either be distributed or transferred to an eligible tax-qualified retirement plan or individual retirement account, as directed by the participant or beneficiary.

Operations of Northfield Bank after the Merger

The Merger Agreement provides for the merger of VSB Bancorp with and into Northfield Bancorp, with Northfield Bancorp as the surviving entity. Following the merger of VSB Bancorp with and into Northfield Bancorp, Victory State Bank will merge with and into Northfield Bank, with Northfield Bank as the surviving bank. The directors and executive officers of Northfield Bank will remain the same following the Merger.

Resale of Shares of Northfield Bancorp Common Stock

All shares of Northfield Bancorp common stock issued to VSB Bancorp’s shareholders in connection with the Merger will be freely transferable. This Proxy Statement/Prospectus does not cover any resales of the shares of Northfield Bancorp common stock to be received by VSB Bancorp’s shareholders upon completion of the Merger, and no person may use this Proxy Statement/Prospectus in connection with any resale.

Time of Completion

Unless the parties agree otherwise and unless the Merger Agreement has otherwise been terminated, and subject to the satisfaction or waiver of all conditions to the closing of the Merger, the closing of the Merger will take place no later than ten business days following the latest to occur of the receipt of all required regulatory approvals, including the expiration of any waiting periods, or the approval of the Merger by VSB Bancorp shareholders.

The Merger will become effective at the time stated in the Certificates of Merger.

Additional Covenants of VSB Bancorp and Northfield Bancorp in the Merger Agreement

Agreement Not to Solicit Other Proposals. VSB Bancorp has agreed not to, and will cause its subsidiaries, and their officers, directors, employees, representatives, affiliates and other agents not to: (1) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal that constitutes or could reasonably be expected to lead to, an acquisition proposal by a third party; (2) participate in discussions or negotiations regarding an acquisition proposal or furnish or otherwise afford access to any third party any information or data with respect to VSB Bancorp or its subsidiaries or otherwise relating to a third-party proposal; (3) release any person from, waive any provisions of, or fail to enforce any confidentiality agreement or standstill agreement to which VSB Bancorp is a party; or (4) enter into any agreement with respect to a third-party acquisition proposal.

An acquisition proposal is a proposal that could reasonably be expected to lead to any of the following or similar transactions:

| • | any merger, consolidation, recapitalization, share exchange, liquidation, dissolution, or other similar transaction involving VSB Bancorp or its subsidiaries;

| • | any sale, lease or other disposition of assets of VSB Bancorp or its subsidiaries and representing, in the aggregate, 25% or more of VSB Bancorp’s consolidated assets;

| • | any issuance, sale, or disposition of securities representing 25% or more of the voting power of VSB Bancorp capital stock; and

| • | any tender offer or exchange offer that, if consummated, would result in any third party or group beneficially owning 25% or more of the outstanding shares of capital stock of VSB Bancorp.

Despite the agreement of VSB Bancorp not to solicit other acquisition proposals, VSB Bancorp may generally negotiate or have discussions with, or provide information to, a third party who makes a bona fide unsolicited written acquisition proposal before the VSB Bancorp shareholders meeting to vote on the Merger Agreement, provided that the VSB Bancorp board of directors determines: (1) in its good faith, after consultation with its outside legal counsel and independent financial advisor, that the failure to take such action would reasonably be expected to violate the directors’ fiduciary obligations under applicable law; and (2) that the acquisition proposal constitutes or is reasonably likely to lead to a superior proposal, meaning that it is: (x) reasonably likely to result in a transaction more favorable to the VSB Bancorp shareholders from a financial point of view than the Merger; (y) is, in light of the other items of such proposal, more favorable to the VSB Bancorp shareholders than the Merger, considering, among other things, and material regulatory approvals and other timing risks; and (3) is reasonably likely to be completed on the terms proposed.

Before entering into negotiations or discussions with a third party, VSB Bancorp must provide Northfield Bancorp with at least three business days prior notice of its determination and have received from the third party a confidentiality agreement with terms no less favorable to VSB Bancorp than those contained in the confidentiality agreement between Northfield Bancorp and VSB Bancorp.

If VSB Bancorp receives an acquisition proposal or information request from a third party or seeks to enter into negotiations with a third party regarding a superior proposal, VSB Bancorp must promptly notify Northfield Bancorp (and in any event within 24 hours) of the receipt of the acquisition proposal or information request and provide Northfield Bancorp with information about the third party and its proposal or information request.

Certain Other Covenants. The Merger Agreement also contains other agreements relating to the conduct of Northfield Bancorp and VSB Bancorp before consummation of the Merger, including the following:

| • | VSB Bancorp will cause one or more of its representatives to confer with representatives of Northfield Bancorp to inform Northfield Bancorp regarding VSB Bancorp’s operations at such times as Northfield Bancorp may reasonably request, and shall promptly notify Northfield Bancorp of any material change in VSB Bancorp’s business;

| • | each party will meet with the other party on a regular basis to discuss and plan for the conversion of VSB Bancorp’s data processing and related electronic information systems;

| • | VSB Bancorp will provide Northfield Bancorp information regarding nonperforming assets and other information related to loans;

| • | VSB Bancorp will permit Northfield Bancorp, at its own expense, to conduct a Phase I Environmental Site Assessment at each branch office and other property owned by VSB Bancorp (and, to the extent permitted at any branch leased by VSB Bancorp) and to the extent such Phase I recommends performance of a Phase II Environmental Site Assessment, to conduct a Phase II Environmental Site Assessment;

| • | VSB Bancorp will take all actions necessary to convene a meeting of its shareholders to vote on the Merger Agreement and the Merger. VSB Bancorp’s board of directors will recommend at its shareholders meeting that the shareholders vote to adopt the Merger Agreement and the Merger and will use commercially reasonable efforts to solicit shareholders’ approval. However, the VSB Bancorp board of directors may recommend a superior proposal to its shareholders, or fail to make a recommendation in favor of approval of the Merger Agreement, or withdraw, qualify or modify a recommendation in favor of approval of the Merger Agreement if, following the receipt of an acquisition proposal that the VSB Bancorp board has determined constitutes a superior proposal, VSB Bancorp’s board of directors, after consultation with and consideration of the advice of its outside legal counsel and financial advisor, determines, in good faith, that failing to take any of the actions described above would reasonably likely violate its fiduciary duties under applicable law; and

| • | before completion of the Merger, Northfield Bancorp will list on the Nasdaq Global Select Market, subject to official notice of issuance, the shares of Northfield Bancorp common stock that Northfield Bancorp will issue in exchange for shares of VSB Bancorp common stock in the Merger.

| • | by either party, if a required regulatory approval or nonobjection is denied or any court of competent jurisdiction or governmental entity prohibits the consummation of the Merger;

| • | by either party, if the conditions to completion of the Merger cannot be satisfied or fulfilled by October 31, 2020, or such later date as agreed to by the parties, unless the failure to complete the Merger by that time was due to such party’s material breach of any representation, warranty, covenant or other agreement provided in the Merger Agreement;

| • | by Northfield Bancorp if (a) VSB Bancorp has materially breached its obligations with respect to its vote of shareholders or its obligations not to solicit third-party acquisition proposals, or (b) the VSB Bancorp board of directors does not publicly recommend in this Proxy Statement/Prospectus approval of the Merger Agreement and the Merger or, if after making such recommendation, the VSB Bancorp board of directors approves or recommends the approval of a superior proposal and withdraws, qualifies or modifies its recommendation to the VSB Bancorp shareholders to vote in favor of the Merger Agreement and the Merger;

| • | the number obtained by dividing the average of the daily closing prices of Northfield Bancorp common stock for the ten consecutive trading days immediately preceding the Determination Date is less than $14.56; and

| • | the number obtained by dividing (1) the average of the daily closing prices of Northfield Bancorp common stock for the ten consecutive trading days immediately preceding the Determination Date by (2) $17.13 is less than the number obtained by dividing (x) the average of the daily closing prices for the ten consecutive trading days immediately preceding the Determination Date of the SNL Small Cap U.S. Bank and Thrift Index (the “Final Index Price”) by (y) the closing value of the SNL Small Cap U.S. Bank and Thrift Index on the last trading date immediately preceding the public announcement of the entry into the Merger Agreement (the “Initial Index Price”), minus 0.15 (the “Index Ratio”).

TABLE OF CONTENTS

If VSB Bancorp elects to exercise its termination right as described above, it must give written notice to Northfield Bancorp. During the three business day period commencing with its receipt of such notice, Northfield Bancorp will have the option to increase the consideration to be received by the holders of VSB Bancorp common stock by adjusting the exchange ratio to equal the lesser of (x) a number (rounded to the nearest one one-thousandth) obtained by dividing (A) the product of $17.13, the exchange ratio as then in effect and the Index Ratio minus 0.15 by (B) the average daily closing price of Northfield Bancorp common stock for the ten consecutive trading days preceding the Determination Date and (y) a number obtained by dividing (A) $17.13 by (B) the average daily closing price of Northfield Bancorp common stock for the ten consecutive trading days preceding the Determination Date, and multiplying the quotient by the exchange ratio as then in effect and 0.85. If within such three business day period, Northfield Bancorp delivers written notice to VSB Bancorp that it intends to proceed with the Merger by paying such additional consideration as contemplated by the preceding sentence, then no termination will have occurred and the Merger Agreement will remain in full force and effect in accordance with its terms (except that the exchange ratio will have been so modified as described above).

Termination Fee

The Merger Agreement requires VSB Bancorp to pay Northfield Bancorp a fee of $2.5 million if the Merger Agreement is terminated in certain circumstances that involve a competing offer. Specifically, VSB Bancorp must pay the termination fee if Northfield Bancorp terminates the Merger Agreement as a result of a breach by VSB Bancorp of its covenant regarding the solicitation of competing offers or VSB Bancorp’s failure to call a shareholders’ meeting or if VSB Bancorp’s board of directors fails to publicly recommend approval of the Merger or withdraws, qualifies, or modified its recommendation to approve the Merger.

VSB Bancorp also must pay the termination fee if (1) VSB Bancorp terminates the Merger Agreement because it has accepted a superior proposal or (2) VSB Bancorp enters into a definitive merger agreement, with a party who made an acquisition proposal prior to termination of the Merger Agreement, within one year of Northfield Bancorp terminating the Merger Agreement due to VSB Bancorp’s willful breach of a representation, warranty or covenant or failure of VSB Bancorp’s shareholders to approve the Merger Agreement.

Expenses

Each of Northfield Bancorp and VSB Bancorp will pay its own costs and expenses incurred in connection with the Merger. In the event of a termination of the Merger Agreement because of a willful breach of any representation, warranty, covenant or agreement contained in the Merger Agreement, the breaching party will remain liable for any and all damages, costs and expenses, including all reasonable attorneys’ fees sustained or incurred by the non-breaching party as a result or in connection therewith or in connection with enforcing its rights under the Merger Agreement.

Changing the Terms of the Merger Agreement

Before the completion of the Merger, Northfield Bancorp and VSB Bancorp may agree to waive, amend or modify any provision of the Merger Agreement. However, after the vote by VSB Bancorp shareholders, Northfield Bancorp and VSB Bancorp may not make any amendment or modification that would reduce the amount or alter the kind of consideration to be received by VSB Bancorp’s shareholders under the terms of the Merger Agreement.

TABLE OF CONTENTS

DESCRIPTION OF NORTHFIELD BANCORP CAPITAL STOCK

The following summary describes the material terms of Northfield Bancorp’s capital stock and is subject to, and qualified by, Northfield Bancorp’s certificate of incorporation and bylaws and applicable Delaware law. See “Where You Can Find More Information” as to how to obtain a copy of Northfield Bancorp’s certificate of incorporation and bylaws.

General

Northfield Bancorp is authorized to issue 150,000,000 shares of common stock having a par value of $0.01 per share, and 25,000,000 shares of preferred stock having a par value of $0.01 per share. At [record date], shares of common stock were outstanding. At that date, no preferred shares were outstanding.

Common Stock

Voting Rights. Holders of common stock of Northfield Bancorp have exclusive voting rights in Northfield Bancorp. They elect Northfield Bancorp’s board of directors and act on other matters that are required to be presented to them under Delaware law or that are otherwise presented to them by the board of directors. Each holder of common stock is entitled to one vote per share and does not have any right to cumulate votes in the election of directors. However, any person who beneficially owns more than 10% of the then-outstanding shares of Northfield Bancorp’s common stock is not entitled or permitted to vote any shares of common stock held in excess of the 10% limit. If Northfield Bancorp issues shares of preferred stock, holders of the preferred stock may also possess voting rights. The approval of 85% of Northfield Bancorp’s outstanding common stock is required to amend certain provisions of Northfield Bancorp’s certificate of incorporation, including the 10% voting limitation, the requirements to call special meetings of the stockholders, the classification, removal, appointment and election of directors and the amendment of the bylaws.

Dividends. Delaware law generally limits dividends to Northfield Bancorp’s capital surplus or, if there is no capital surplus, Northfield Bancorp’s net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. The payment of dividends by Northfield Bancorp is also subject to limitations that are imposed by law and applicable regulation, including restrictions on payments of dividends that would reduce Northfield Bancorp’s assets below the then-adjusted balance of its liquidation account. The holders of common stock of Northfield Bancorp are entitled to receive and share equally in dividends as may be declared by our board of directors out of funds legally available therefor. If Northfield Bancorp issues shares of preferred stock, the holders thereof may have a priority over the holders of the common stock with respect to dividends.

The Federal Reserve has issued a policy statement providing that dividends should be paid only out of current earnings and only if the holding company’s prospective rate of earnings retention is consistent with its capital needs, asset quality and overall financial condition. Federal regulatory guidance also provides for prior regulatory consultation with respect to capital distributions in certain circumstances such as where the holding company’s net income for the past four quarters, net of dividends previously paid over that period, is insufficient to fully fund the dividend or the holding company’s overall rate or earnings retention is inconsistent with its capital needs and overall financial condition.

Liquidation. In the event of any liquidation, dissolution or winding up of Northfield Bank, Northfield Bancorp, as the holder of 100% of Northfield Bank’s capital stock, would be entitled to receive all assets of Northfield Bank available for distribution, after payment or provision for payment of all debts and liabilities of Northfield Bank, including all deposit accounts and accrued interest thereon, and after distribution of the balance in the liquidation account to certain eligible depositors established in connection with Northfield Bancorp’s second-step conversion stock offering in 2012. In the event of liquidation, dissolution or winding up of Northfield Bancorp, the holders of its common stock would be entitled to receive, after payment or provision for payment of all its debts and liabilities (including payments with respect to its liquidation account), all of the assets of Northfield Bancorp available for distribution. If preferred stock is issued, the holders thereof may have a priority over the holders of the common stock in the event of liquidation or dissolution.

Preemptive Rights. Holders of the common stock of Northfield Bancorp are not entitled to preemptive rights with respect to any shares that may be issued. The common stock is not subject to redemption.

TABLE OF CONTENTS

Preferred Stock

Northfield Bancorp’s certificate of incorporation authorizes its board of directors, without stockholder action, to issue preferred stock in one or more series and to establish the designations, dividend rates and rights, dissolution or liquidation rights, preferences, price and terms and conditions on which shares may be redeemed, terms and conditions for conversion or exchange into any other class or series of the stock, voting rights and other terms. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, adversely affect the voting power of the holders of common stock and could have the effect of delaying, deferring or preventing a change in control of Northfield Bancorp.

Certain Certificate of Incorporation and Bylaw Provisions Affecting Northfield Bancorp Common Stock

Northfield Bancorp’s certificate of incorporation and bylaws contain several provisions that may make Northfield Bancorp a less attractive target for an acquisition of control by anyone who does not have the support of Northfield Bancorp’s board of directors. Such provisions include, among other things, the requirement of a supermajority vote of stockholders or directors to approve certain business combinations and other corporate actions, special procedural rules regarding nominations for election to the board of directors or the introduction of new business at meetings of stockholders, a staggered board of directors, and a vote limitation on shares owned in excess of 10% of Northfield Bancorp’s outstanding shares. The foregoing description is qualified in its entirety by reference to Northfield Bancorp’s certificate of incorporation and bylaws.

Restrictions on Ownership

Under the Change in Bank Control Act, no person or entity may acquire control of a savings and loan holding company, such as Northfield Bancorp, unless the Federal Reserve has been given 60 days prior written notice and has not disapproved the proposed acquisition, taking into consideration certain factors, including the financial and managerial resources of the acquiror and the competitive effects of the acquisition. Control, as defined under federal law, means ownership, control of or holding irrevocable proxies representing more than 25% of any class of voting stock, control in any manner of the election of a majority of Northfield Bancorp’s directors, or a determination by the regulator that the acquiror has the power, directly or indirectly, to exercise a controlling influence over the management or policies of Northfield Bancorp. Acquisition of more than 10% of any class of a savings and loan holding company’s voting stock constitutes a rebuttable determination of control under Federal Reserve Board regulations where, as is the case with Northfield Bancorp, the issuer has registered securities under Section 12 of the Securities Exchange Act of 1934. Any company that acquires such control becomes a “savings and loan holding company” subject to registration, examination and regulation by the Federal Reserve.

Transfer Agent and Registrar

The Transfer Agent and Registrar for Northfield Bancorp’s common stock is Broadridge Corporate Issuer Solutions, Inc., Brentwood, New York.

COMPARISON OF RIGHTS OF SHAREHOLDERS

The rights of stockholders of Northfield Bancorp are currently governed by Northfield Bancorp’s certificate of incorporation and bylaws and by Delaware law. The rights of shareholders of VSB Bancorp are currently governed by VSB Bancorp’s certificate of incorporation and bylaws and by New York law. If the Merger is completed, VSB Bancorp shareholders who receive Northfield Bancorp common stock will become Northfield Bancorp stockholders and, as a result, their rights will be governed by Northfield Bancorp’s certificate of incorporation and bylaws and Delaware law.

However, if the date of the annual meeting is advanced by more than 30 days or delayed by more than 30 days from the anniversary date of the preceding year’s annual meeting, notice by the stockholder will be timely if it is received not later than the 10th day following the day on which public announcement of the date of such meeting is first made.

At such adjourned meeting at which a quorum is present or represented, any business may be transacted which might have been transacted at the meeting as originally notified. The stockholders present at a duly organized meeting may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum. | • | A lesser number when not constituting a quorum may adjourn the meeting from time to time until a quorum shall be present or represented.

Limitations of Personal Liability of Officers and Directors and Indemnification
Northfield Bancorp | VSB Bancorp
• | Northfield Bancorp’s certificate of incorporation limits liability of directors for monetary damages, except a director may be liable (1) for a breach of duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (3) under Section 174 of the DGCL or (4) for any transaction from which the director derived an improper personal benefit. | • | VSB Bancorp’s certificate of incorporation provides that a director of VSB Bancorp will not be personally liable to VSB Bancorp or its shareholders for damages for breach for any breach of duty in his or her capacity as a director, provided that this provision shall not eliminate or limit liability for any act or omission described in Section 402(b)(1) and 402(b)(2) of the NYBCL.
• | Northfield Bancorp certificate of incorporation provides that Northfield Bancorp will indemnify its current and former directors and officers to the fullest extent permitted by Delaware law. Under Delaware law, a corporation may indemnify its directors, officers, and employees against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in proceedings arising because of the person's relationship to the company, so long as the individual acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interest of the company (and, in the case of a criminal proceeding, so long as the individual had no reasonable cause to believe his conduct was unlawful). To the extent a person eligible for indemnification is successful on the merits or otherwise in defense in such an action, indemnification for expenses actually and reasonably incurred is mandatory. Delaware law provides that a company may pay expenses incurred in advance of the final disposition of the proceeding provided the company receives from the individual a written undertaking to repay the advanced amounts if it is ultimately determined that the individual was not entitled to be indemnified. A similar standard for indemnification applies in a shareholder “derivative” claim (i.e., an action by or in the right of the company) except that indemnification only extends to expenses incurred in defense of such a proceeding and except that, where the individual has been found liable to the company, indemnification must be approved by the court. | • | VSB Bancorp’s by-laws provide that VSB Bancorp shall indemnify and advance the expenses of any director, officer or employee to the full extent permitted by New York law. Under New York law, a corporation may indemnify any person made, or threatened to be made, a party to an action or proceeding (other than one by or in the right of the corporation to procure a judgment in its favor), whether civil or criminal, including an action by or in the right of any other corporation of any type or kind, domestic or foreign, or any partnership, joint venture, trust, employee benefit plan or other enterprise, which any director or officer of the corporation served in any capacity at the request of the corporation, by reason of the fact that he, his testator or intestate, was a director or officer of the corporation, or served such other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise in any capacity, against judgments, fines, amounts paid in settlement and reasonable expenses, including attorneys' fees actually and necessarily incurred as a result of such action or proceeding, or any appeal therein, if such director or officer acted, in good faith, for a purpose which he reasonably believed to be in, or, in the case of service for any other corporation or any partnership, joint venture, trust, employee benefit plan or other enterprise, not opposed to, the best interests of the corporation and, in criminal actions or proceedings, in addition, had no reasonable cause to believe that his conduct was unlawful. The termination of any such civil or criminal action or proceeding by judgment, settlement, conviction or upon a plea of nolo contendere, or its equivalent, shall not in itself create a presumption that any such director or officer did not act, in good faith, for a purpose which he reasonably believed to be in, or, in the case of service for any other corporation or any partnership, joint venture, trust, employee benefit plan or other enterprise, not opposed to, the best

A corporation may indemnify any person made, or threatened to be made, a party to an action by or in the right of the corporation to procure a judgment in its favor by reason of the fact that he, his testator or intestate, is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a director or officer of any other corporation of any type or kind, domestic or foreign, of any partnership, joint venture, trust, employee benefit plan or other enterprise, against amounts paid in settlement and reasonable expenses, including attorneys' fees, actually and necessarily incurred by him in connection with the defense or settlement of such action, or in connection with an appeal therein, if such director or officer acted, in good faith, for a purpose which he reasonably believed to be in, or, in the case of service for any other corporation or any partnership, joint venture, trust, employee benefit plan or other enterprise, not opposed to, the best interests of the corporation, subject to the limitations set forth in Section 722 of the NYBCL.

Dissenters’ Rights
Northfield Bancorp | VSB Bancorp

All shares of VSB Bancorp Common Stock held in the treasury of VSB Bancorp and each share of VSB Bancorp Common Stock owned by Northfield Bancorp or any direct or indirect wholly owned Subsidiary of Northfield Bancorp immediately prior to the Effective Time (other than shares held in a fiduciary capacity or in connection with debts previously contracted) (collectively, “Treasury Stock”), shall, at the Effective Time, cease to exist, and such shares shall be canceled as promptly as practicable thereafter, and no payment or distribution shall be made in consideration therefor.

3.1.3. Each share of VSB Bancorp Common Stock issued and outstanding immediately prior to the Effective Time (other than Treasury Stock and Dissenting Shares) shall become and be converted into, as provided in and subject to the limitations set forth in this Agreement, the right to receive a number of shares of Northfield Bancorp Common Stock determined on the basis of the Exchange Ratio (the “Merger Consideration”).

3.2.2. Exchange of Certificates. Northfield Bancorp shall take all steps necessary to cause the Exchange Agent, as soon as is reasonably practicable, but in no event later than three (3) business days after the Effective Time, to mail to each holder of a Certificate or Certificates, a letter of transmittal and instructions for use in effecting the surrender of the Certificates to the Exchange Agent in exchange for the Merger Consideration and cash in lieu of fractional shares into which the VSB Bancorp Common Stock represented by such Certificates shall have been converted as a result of the Merger. The letter of transmittal (which shall be subject to the reasonable approval of VSB Bancorp) shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent. Upon proper surrender of a Certificate for exchange and cancellation to the Exchange Agent, together with a properly completed letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration to which such holder of VSB Bancorp Common Stock shall have become entitled pursuant to Section 3.1.3 hereof, and the Certificate so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any cash payable in lieu of fractional shares or any unpaid dividends and distributions, if any, payable to holders of Certificates.

The holder of a Certificate that prior to the Merger represented issued and outstanding VSB Bancorp Common Stock shall have no rights, after the Effective Time, with respect to such VSB Bancorp Common Stock except to surrender the Certificate in exchange for the Merger Consideration as provided in this Agreement, or, as to Dissenting Shares, such rights as

A-13

TABLE OF CONTENTS

provided under the New York Business Corporation Law. No dividends or other distributions declared after the Effective Time with respect to Northfield Bancorp Common Stock shall be paid to the holder of any unsurrendered Certificate until the holder thereof shall surrender such Certificate in accordance with this Section 3.2. After the surrender of a Certificate in accordance with this Section 3.2, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore had become payable with respect to shares of Northfield Bancorp Common Stock represented by such Certificate.

3.2.4. Surrender by Persons Other than Record Holders. If the Person surrendering a Certificate and signing the accompanying letter of transmittal is not the record holder thereof, then it shall be a condition of the payment of the Merger Consideration that: (i) such Certificate is properly endorsed to such Person or is accompanied by appropriate stock powers, in either case signed exactly as the name of the record holder appears on such Certificate, and is otherwise in proper form for transfer, or is accompanied by appropriate evidence of the authority of the Person surrendering such Certificate and signing the letter of transmittal to do so on behalf of the record holder; and (ii) the Person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other taxes required by reason of the payment to a Person other than the registered holder of the Certificate surrendered, or required for any other reason, or shall establish to the satisfaction of the Exchange Agent that such tax has been paid or is not payable.

3.2.5. Closing of Transfer Books. The stock transfer books of VSB Bancorp shall be closed immediately upon the Effective Time and from and after the Effective Time, there shall be no transfers on the stock transfer books of VSB Bancorp of the VSB Bancorp Common Stock that was outstanding immediately prior to the Effective Time.

3.2.6. Return of Exchange Fund. At any time following the six (6) month period after the Effective Time, Northfield Bancorp shall be entitled to require the Exchange Agent to deliver to it any portions of the Exchange Fund that had been made available to the Exchange Agent and not disbursed to holders of Certificates (including, without limitation, all interest and other income received by the Exchange Agent in respect of all funds made available to it), and thereafter such holders shall be entitled to look to Northfield Bancorp (subject to abandoned property, escheat and other similar laws) with respect to any Merger Consideration that may be payable upon due surrender of the Certificates held by them. Notwithstanding the foregoing, neither Northfield Bancorp nor the Exchange Agent shall be liable to any holder of a Certificate for any Merger Consideration delivered in respect of such Certificate to a public official pursuant to any abandoned property, escheat or other similar law.

3.2.7. Lost, Stolen or Destroyed Certificates. In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and the posting by such Person of a bond in such amount as the Exchange Agent may reasonably direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration deliverable in respect thereof.

3.2.8. Withholding. The Exchange Agent or Northfield Bancorp will be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement or the transactions contemplated hereby to any holder of VSB Bancorp Common Stock such amounts as the Exchange Agent is required to deduct and withhold with respect to the making of such payment under the Code, or any applicable provision of U.S. federal, state, local or non-U.S. tax law. To the extent that such amounts are properly withheld by the Exchange Agent or Northfield Bancorp, such withheld amounts will be treated for all purposes of this Agreement as having been paid to the holder of the VSB Bancorp Common Stock in respect of whom such deduction and withholding were made by the Exchange Agent or Northfield Bancorp.

6.2. Current Information.

6.2.1. Except to the extent prohibited by a Bank Regulator pursuant to regulatory policy, during the period from the date of this Agreement to the Effective Time, VSB Bancorp will cause one or more of its representatives to confer with representatives of Northfield Bancorp and report the general status of its ongoing operations at such times as Northfield Bancorp may reasonably request. VSB Bancorp will promptly notify Northfield Bancorp of any material change in the normal course of its business or in the operation of its properties and, to the extent permitted by applicable law, of any governmental complaints, investigations or hearings (or communications indicating that the same may be contemplated), or the institution or the threat of material litigation involving VSB Bancorp or any VSB Bancorp Subsidiary. Any information provided pursuant to this Section 6.2.1 will be subject to the Confidentiality Agreement and may only be used to facilitate the transactions contemplated hereby.

6.2.2. VSB Bancorp and Northfield Bank shall meet on a regular basis to discuss and plan for the conversion of VSB Bancorp’s data processing and related electronic informational systems to those used by Northfield Bank, which planning shall include, but not be limited to: discussion of the possible termination by VSB Bancorp of third-party service provider arrangements effective at the Effective Time or at a date thereafter; non-renewal of personal property leases and software licenses used by VSB Bancorp in connection with its systems operations; retention of outside consultants and additional employees to assist with the conversion and outsourcing, as appropriate, of proprietary or self-provided system services, it being understood that VSB Bancorp shall not be obligated to take any such action prior to the receipt of all required Regulatory Approvals and approval of the VSB stockholders. If VSB Bancorp takes, at the request of Northfield Bank, any action relative to third parties to facilitate the conversion that results in the imposition of any termination fees or charges, Northfield Bank shall pay any such fees and charges directly to such third parties, and shall indemnify VSB Bancorp for the costs of reversing the conversion process, if for any reason the Merger is not consummated for any reason other than a breach of this Agreement by VSB Bancorp, or a termination of this Agreement under Section 11.1.8 or 11.1.9.

6.2.3. VSB Bancorp shall provide Northfield Bancorp, substantially contemporaneously with the delivery to the Board of Directors of VSB Bancorp, of the materials for the monthly board meeting, which shall include a written list of nonperforming assets as of the prior month end (the term “nonperforming assets,” for purposes of this subsection, means (i) loans that are “troubled debt restructuring” as defined in ASC 310-40, Receivables, “Troubled Debt Restructuring by Creditors,” as updated by Accounting Standards Update 2011-02”, (ii) loans on nonaccrual, (iii) OREO, (iv) all loans ninety (90) days or more past due as of the end of such month, (iv) impaired loans and (v) loans classified as “substandard,” “doubtful” or “loss”).

6.2.4. VSB Bancorp shall promptly inform Northfield Bancorp, to the extent permitted by applicable law, upon receiving notice of any legal, administrative, arbitration or other proceedings, demands, notices, audits or investigations (by any federal, state or local commission, agency or board) relating to the alleged liability of VSB Bancorp or any VSB Bancorp Subsidiary under any labor or employment law.

TABLE OF CONTENTS

properties, operations, obligations and liabilities, including, but not limited to, all books of account (including the general ledger), tax records, minute books of directors’ (other than minutes that discuss the transactions contemplated by this Agreement or any other subject matter VSB Bancorp reasonably determines should be treated as confidential) and stockholders’ meetings, organizational documents, bylaws, material contracts and agreements, filings with any regulatory authority, litigation files, plans affecting employees, and any other business activities or prospects in which Northfield Bancorp or its Subsidiaries may have a reasonable interest; provided, however, that VSB Bancorp shall not be required to take any action that would provide access to or to disclose information where such access or disclosure, in VSB Bancorp’s reasonable judgment, would: (i) interfere with the normal conduct of VSB Bancorp’s business; (ii) would violate or prejudice the rights or business interests or confidences of any customer; or (iii) contravene any law, rule, regulation, order, judgment or decree. VSB Bancorp shall provide and shall request its auditors to provide Northfield Bancorp with such historical financial information regarding it (and related audit reports and consents) as Northfield Bancorp may reasonably request for Securities Laws disclosure purposes. Northfield Bancorp shall use commercially reasonable efforts to minimize any interference with VSB Bancorp’s regular business operations during any such access to VSB Bancorp’s property, books and records.

6.3.2. VSB Bancorp shall permit Northfield Bancorp, at Northfield Bancorp’s own expense, to cause a “Phase I Environmental Site Assessment” (the “Phase I”) (in conformance with American Society for Testing Materials (“ASTM”) Standard 1527-13, as amended) to be performed at each branch office and other property owned by VSB Bancorp, and, to the extent permitted by any lease governing VSB Bancorp’s lease of any branch, at each branch leased by VSB Bancorp, at any time prior to the Closing Date, and to the extent such Phase I recommends performance of a Phase II Environmental Site Assessment (the “Phase II”) prior to the Closing Date only to the extent that the Phase II is within the scope of additional testing recommended by the Phase I to be performed as a result of a “Recognized Environmental Condition” (as such term is defined by the ASTM) that was discovered in the Phase I, and provided that as to any Phase II performed at a branch that VSB Bancorp leases, the landlord pursuant to the applicable lease has consented to such Phase II if such consent is necessary pursuant to the lease. VSB Bancorp will use its commercially reasonable efforts (at no cost to VSB Bancorp) to obtain such landlord consent. Prior to performing any Phase II, Northfield Bancorp will provide VSB Bancorp with a copy of its proposed work plan and Northfield Bancorp will cooperate in good faith with VSB Bancorp to address any comments or suggestions made by VSB Bancorp regarding the work plan. Northfield Bancorp and its environmental consultant shall conduct all environmental assessments pursuant to this Section 6.3.2 at mutually agreeable times to eliminate or minimize to the greatest extent possible interference with the operation of VSB Bancorp’s business, and Northfield Bancorp shall maintain or cause to be maintained reasonably adequate insurance with respect to any assessment conducted hereunder. Northfield Bancorp shall be required to restore each property to substantially its pre-assessment condition. All costs and expenses incurred in connection with any Phase I or Phase II and any restoration and clean up, shall be borne solely by Northfield Bancorp.

6.3.3. Notwithstanding anything to the contrary contained in this Section 6.3, in no event shall Northfield Bancorp have access to any information that, based on advice of VSB Bancorp’s counsel, would (a) reasonably be expected to waive any material legal privilege, (b) result in the disclosure of any trade secrets of third parties or (c) violate any obligation of VSB Bancorp with respect to confidentiality so long as, with respect to confidentiality, to the extent specifically requested by Northfield Bancorp, VSB Bancorp has made commercially reasonable efforts to obtain a waiver regarding the possible disclosure from the third party to whom it owes an obligation of confidentiality. Further, Northfield Bancorp shall not have access to information that relates to the Merger or an Acquisition Proposal. All requests made pursuant to this Section 6.3 shall be directed to an executive officer of VSB Bancorp or such Person or Persons as may be designated by VSB Bancorp. All information received pursuant to this Section 6.3 shall be governed by the terms of the Confidentiality Agreement.

6.4. Financial and Other Statements.

6.4.1. Promptly upon receipt thereof, VSB Bancorp will furnish to Northfield Bancorp copies of each annual, interim or special internal or external audit of the books of VSB Bancorp and each VSB Bancorp Subsidiary made by VSB Bancorp, its independent auditors or other auditors, and copies of all internal control reports submitted to VSB Bancorp by such auditors in connection with each annual, interim or special internal or external audit of the books of VSB Bancorp and the VSB Bancorp Subsidiaries made by its auditors.

VSB Bancorp shall maintain, and cause the VSB Bancorp Subsidiaries to maintain, insurance in such amounts that are reasonable to cover such risks as are customary in relation to the character and location of its properties and the nature of its business.

6.6. Disclosure Supplements.

From time to time prior to the Effective Time, VSB Bancorp will promptly supplement or amend the VSB Bancorp DISCLOSURE SCHEDULE delivered in connection herewith with respect to any matter hereafter arising that, if existing, occurring or known at the date of this Agreement, would have been required to be set forth or described in such VSB Bancorp DISCLOSURE SCHEDULE or that is necessary to correct any information in such VSB Bancorp DISCLOSURE SCHEDULE that has been rendered inaccurate thereby. No supplement or amendment to such VSB Bancorp DISCLOSURE SCHEDULE shall have any effect for determining satisfaction of the conditions set forth in Article IX.

6.7. Consents and Approvals of Third Parties; Proxy Solicitor.

VSB Bancorp shall use all commercially reasonable efforts, and shall cause each VSB Bancorp Subsidiary to use all commercially reasonable efforts, to obtain as soon as practicable all consents and approvals of any other persons necessary or desirable for the consummation of the transactions contemplated by this Agreement. Without limiting the generality of the foregoing, VSB Bancorp shall, if requested by Northfield Bancorp, utilize the services of a professional proxy soliciting firm to assist in obtaining the stockholder vote required to be obtained by it hereunder, the selection of which shall be subject to the approval of Northfield Bancorp, which approval shall not be unreasonably delayed, withheld or conditioned.

6.8. All Reasonable Efforts.

Subject to the terms and conditions herein provided, VSB Bancorp agrees to use, and agrees to cause each VSB Bancorp Subsidiary to use, all commercially reasonable efforts to take, or cause to be taken, all action and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to consummate and make effective the transactions contemplated by this Agreement.

6.9. Failure to Fulfill Conditions.

If VSB Bancorp determines (i) that a condition to its obligation to complete the Merger cannot be fulfilled, or (ii) any event, condition, change or occurrence that individually or in the aggregate has, or that, so far as reasonably can be foreseen at the time of its occurrence, is reasonably likely to result in a Material Adverse Effect, it will promptly notify Northfield Bancorp.

6.10. No Solicitation.

6.10.1. VSB Bancorp shall not, and shall cause the VSB Bancorp Subsidiaries and the respective officers, directors, employees, investment bankers, financial advisors, attorneys, accountants, consultants, affiliates and other agents (collectively, the “VSB Bancorp Representatives”) not to, directly or indirectly: (i) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal that constitutes, or could reasonably be expected to lead to, an Acquisition Proposal; (ii) participate in any discussions or negotiations regarding any Acquisition Proposal or furnish, or otherwise afford access, to any Person (other than Northfield Bancorp) any information or data with respect to VSB Bancorp or any of the VSB Bancorp Subsidiaries or otherwise relating to an Acquisition Proposal; (iii) release

A-42

TABLE OF CONTENTS

any Person from, waive any provisions of, or fail to enforce any confidentiality agreement or standstill agreement to which VSB Bancorp is a party; or (iv) enter into any agreement, agreement in principle or letter of intent with respect to any Acquisition Proposal or approve or resolve to approve any Acquisition Proposal or any agreement, agreement in principle or letter of intent relating to an Acquisition Proposal. Any violation of the foregoing restrictions by VSB Bancorp or any VSB Bancorp Representative, whether or not such Representative is so authorized and whether or not such VSB Bancorp Representative is purporting to act on behalf of VSB Bancorp or otherwise, shall be deemed to be a breach of this Agreement by VSB Bancorp. VSB Bancorp and the VSB Bancorp Subsidiaries shall, and shall cause each of the VSB Bancorp Representatives to, immediately cease and cause to be terminated any and all existing discussions, negotiations, and communications with any Persons with respect to any existing or potential Acquisition Proposal.

For purposes of this Agreement, “Acquisition Proposal” shall mean any inquiry, offer or proposal (other than an inquiry, offer or proposal from Northfield Bancorp), whether or not in writing, contemplating, relating to, or that could reasonably be expected to lead to, an Acquisition Transaction. For purposes of this Agreement, “Acquisition Transaction” shall mean (A) any transaction or series of transactions, including by way of merger, consolidation, recapitalization, share exchange, liquidation, dissolution or similar transaction involving VSB Bancorp or any of the VSB Bancorp Subsidiaries; (B) any transaction pursuant to which any third party or group acquires or would acquire (whether through sale, lease or other disposition), directly or indirectly, any assets of VSB Bancorp or any of the VSB Bancorp Subsidiaries representing, in the aggregate, twenty-five percent (25%) or more of the assets of VSB Bancorp and the VSB Bancorp Subsidiaries on a consolidated basis; (C) any issuance, sale or other disposition of (including by way of merger, consolidation, share exchange or any similar transaction) securities (or options, rights or warrants to purchase or securities convertible into, such securities) representing twenty-five percent (25%) or more of the votes attached to the outstanding securities of VSB Bancorp or any of the VSB Bancorp Subsidiaries; (D) any tender offer or exchange offer that, if consummated, would result in any third party or group beneficially owning twenty-five percent (25%) or more of any class of equity securities of VSB Bancorp or any of the VSB Bancorp Subsidiaries; or (E) any transaction that is similar in form, substance or purpose to any of the foregoing transactions, or any combination of the foregoing.

6.10.2. Notwithstanding Section 6.10.1, VSB Bancorp may take any of the actions described in clause (ii) of Section 6.10.1 only if, (i) VSB Bancorp has received a bona fide unsolicited written Acquisition Proposal, prior to the VSB Bancorp Stockholders Meeting, that did not result from a breach of this Section 6.10; (ii) the Acquisition Proposal constitutes or is reasonably likely to constitute a Superior Proposal; (iii) the VSB Bancorp Board of Directors determines in good faith, after consultation with and having considered the advice of its outside legal counsel and its independent financial advisor, that the failure to take such action would reasonably be expected to violate the directors’ fiduciary obligations to VSB Bancorp’s stockholders under applicable law; (iv) VSB Bancorp has provided Northfield Bancorp with at least three (3) business days prior notice of such determination; and (v) prior to furnishing or affording access to any information or data with respect to VSB Bancorp or any of the VSB Bancorp Subsidiaries or otherwise relating to an Acquisition Proposal or entering into any discussions with a third party, VSB Bancorp receives from such Person a confidentiality agreement with terms no less favorable to VSB Bancorp than those contained in the Confidentiality Agreement. VSB Bancorp shall promptly provide to Northfield Bancorp any non-public information regarding VSB Bancorp or the VSB Bancorp Subsidiaries provided to any other Person that was not previously provided to Northfield Bancorp, such additional information to be provided no later than the date of provision of such information to such other party.

For purposes of this Agreement, “Superior Proposal” shall mean any bona fide written proposal (on its most recently amended or modified terms, if amended or modified) made by a third party to enter into an Acquisition Transaction on terms that the VSB Bancorp Board of Directors determines in its good faith judgment, after consultation with and having considered the advice of outside legal counsel and its financial advisor (i) would, if consummated, result in the acquisition of all, but not less than all, of the issued and outstanding shares of VSB Bancorp Common Stock or all, or substantially all, of the assets of VSB Bancorp and the VSB Bancorp Subsidiaries on a consolidated basis; (ii) would result in a transaction that (A) involves consideration to the holders of the shares of VSB Bancorp Common Stock that is more favorable, from a financial point of view, than the consideration to be paid to the VSB Bancorp Stockholders pursuant to this Agreement, considering, among other things, the nature of the consideration being offered and which proposal is not conditioned upon obtaining additional financing, and (B) is, in light of the other terms of such proposal, more favorable to the VSB Bancorp Stockholders than the Merger and the transactions contemplated by this Agreement, considering,

A-43

TABLE OF CONTENTS

among other things, any material regulatory approvals and other risks associated with the timing of the proposed transaction beyond or in addition to those specifically contemplated hereby; and (iii) is reasonably likely to be completed on the terms proposed, in each case taking into account all legal, financial, regulatory and other aspects of the proposal.

6.10.3. VSB Bancorp shall promptly (and in any event within twenty-four (24) hours) notify Northfield Bancorp in writing if any proposals or offers are received by, any information is requested from, or any negotiations or discussions are sought to be initiated or continued with, VSB Bancorp or any VSB Bancorp Representatives, in each case in connection with any Acquisition Proposal, and such notice shall indicate the name of the Person initiating such discussions or negotiations or making such proposal, offer or information request and the material terms and conditions of any proposals or offers (and, in the case of written materials relating to such proposal, offer, information request, negotiations or discussion, providing copies of such materials (including e-mails or other electronic communications), VSB Bancorp agrees that it shall keep Northfield Bancorp informed, on a current basis, of the status and terms of any such proposal, offer, information request, negotiations or discussions (including any amendments or modifications to such proposal, offer or request).

6.10.4. Subject to Section 6.10.5, neither the VSB Bancorp Board of Directors nor any committee thereof shall (i) withdraw, qualify or modify, or propose to withdraw, qualify or modify, in a manner adverse to Northfield Bancorp in connection with the transactions contemplated by this Agreement (including the Merger), the VSB Bancorp Recommendation (as defined in Section 8.1.1), or make any statement, filing or release, in connection with the VSB Bancorp Stockholders Meeting or otherwise, inconsistent with the VSB Bancorp Recommendation (it being understood that taking a neutral position or no position with respect to an Acquisition Proposal shall be considered an adverse modification of the VSB Bancorp Recommendation); or (ii) approve or recommend, or publicly propose to approve or recommend, any Acquisition Proposal.

6.10.5. Notwithstanding Section 6.10.4, prior to the date of VSB Bancorp Stockholders’ Meeting, the VSB Bancorp Board of Directors may approve or recommend to the stockholders of VSB Bancorp a Superior Proposal and withdraw, qualify or modify the VSB Bancorp Recommendation in connection therewith (a “VSB Bancorp Subsequent Determination”) after the third (3rd) Business Day following Northfield Bancorp’s receipt of a notice (the “Notice of Superior Proposal”) from VSB Bancorp advising Northfield Bancorp that the VSB Bancorp Board of Directors has decided that a bona fide unsolicited written Acquisition Proposal that it received (that did not result from a breach of this Section 6.10) constitutes a Superior Proposal (it being understood that VSB Bancorp shall be required to deliver a new Notice of Superior Proposal in respect of any revised Superior Proposal from such third party or its affiliates that VSB Bancorp proposes to accept and the subsequent notice period shall be three (3) business days) if, but only if, (i) the VSB Bancorp Board of Directors has reasonably determined in good faith, after consultation with and having considered the advice of outside legal counsel and its financial advisor, that the failure to take such actions would be reasonably likely to violate its fiduciary duties to VSB Bancorp’s stockholders under applicable law, and (ii) at the end of such three (3) Business Day period, after taking into account any such adjusted, modified or amended terms as may have been committed to in writing by Northfield Bancorp since its receipt of such Notice of Superior Proposal (provided, however, that Northfield Bancorp shall not have any obligation to propose any adjustments, modifications or amendments to the terms and conditions of this Agreement), the VSB Bancorp Board of Directors has again in good faith made the determination (A) in clause (i) of this Section 6.10.5, and (B) that such Acquisition Proposal constitutes a Superior Proposal. Notwithstanding the foregoing, the changing, qualifying or modifying of the VSB Bancorp Recommendation or the making of a VSB Bancorp Subsequent Determination by the VSB Bancorp Board of Directors shall not change the approval of the VSB Bancorp Board of Directors for purposes of causing any applicable “moratorium,” “control share,” “fair price,” “takeover,” “interested stockholder” or similar law to be inapplicable to this Agreement and the VSB Bancorp Voting Agreements and the transactions contemplated hereby and thereby, including the Merger.

7.4. All Reasonable Efforts.

Subject to the terms and conditions herein provided, Northfield Bancorp agrees to use, and agrees to cause each Northfield Bancorp Subsidiary to use, all commercially reasonable efforts to take, or cause to be taken, all action and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to consummate and make effective the transactions contemplated by this Agreement.

7.5. Failure to Fulfill Conditions.

In the event that Northfield Bancorp determines (i) that a condition to its obligation to complete the Merger cannot be fulfilled, or (ii) any event, condition, change or occurrence that individually or in the aggregate has, or that, so far as reasonably can be foreseen at the time of its occurrence, is reasonably likely to result in, a Material Adverse Effect, it will promptly notify VSB Bancorp.

7.6. Employee Benefits; Advisory Board.

7.6.1 Except as otherwise provided in this Agreement, Northfield Bancorp will review all the VSB Bancorp Compensation and Benefit Plans to determine whether to maintain, terminate or continue such plans on or after the Effective Time. If any VSB Bancorp Compensation and Benefit Plan is frozen or terminated by Northfield Bancorp, former employees of VSB Bancorp or Victory Bank who become employees of Northfield Bancorp or Northfield Bank after the Effective Time (“Continuing Employees”) who were participants in such plan shall be eligible to participate in any Northfield Bancorp Compensation and Benefit Plan of similar character, to extent that one exists (other than any Northfield Bancorp non-qualified deferred compensation plan, employment agreement, change in control agreement, supplemental executive arrangement or equity incentive plan or other similar-type of arrangement). Continuing Employees who become participants in a Northfield Bancorp Compensation and Benefits Plan shall be given credit for meeting eligibility and vesting requirements only (and not for benefit accrual purposes, except that credit for benefit accrual purposes shall be given in the Northfield Bank Employee Savings Plan or any vacation or paid time off plan) in such plans for service as an employee of VSB Bancorp or Victory Bank prior to the Effective Time; provided, however, that credit for prior service shall be given under the Northfield Bank Employee Stock Ownership Plan only for purposes of determining eligibility to participate in such plan and not for vesting purposes, and provided further, that credit for prior service shall not be given under the Northfield Bancorp retiree health plan. This Agreement shall not be construed to limit the ability of Northfield Bancorp or Northfield Bank to terminate the employment of any VSB Bancorp or Victory Bank employee or to review any VSB Bancorp Compensation and Benefit Plan from time to time and to make such changes (including terminating any such plan) as they deem appropriate.

7.6.2 Subject to the requirement of Section 6.13 hereof, Northfield Bancorp shall honor the contractual terms of all employment, consulting, change in control, severance and deferred compensation agreements, if any, listed on VSB Bancorp DISCLOSURE SCHEDULE 4.13.1 (collectively, the “VSB Bancorp Non-Qualified Agreements”), except to the extent any such agreement is superseded or terminated as of, or following, the Effective Time. Notwithstanding anything contained in the VSB Bancorp Non-Qualified Agreements or in this Agreement, no payment shall be made under any Non-Qualified Agreement or otherwise that would constitute a “parachute payment” (as such term is defined in Section 280G of the Code), and to the extent any payments or benefits would constitute a “parachute payment,” such payments and/or benefits will be reduced to the extent necessary to avoid penalties under Section 280G of the Code.

7.6.3 Any employee of VSB Bancorp or Victory Bank who is not a party to an employment, change in control or severance agreement or contract providing severance payments shall, for nine (9) months following the Effective Time, be covered and be eligible to receive severance benefits under the VSB Bancorp Severance Plan set forth in VSB Bancorp DISCLOSURE SCHEDULE 7.6.3 in accordance with the terms of the VSB Bancorp Severance Plan, provided, however that such employee enters into a release of claims against Northfield Bancorp, Northfield Bank and their Affiliates in a customary form reasonably satisfactory to Northfield Bancorp.

7.6.4 In the event of any termination of any VSB Bancorp health plan or consolidation of any such plan with any Northfield Bancorp or Northfield Bank health plan, Northfield Bank shall make available to Continuing Employees and their dependents employer-provided health coverage on the same basis as it provides such coverage to Northfield Bank employees. Unless a Continuing Employee affirmatively terminates coverage under a VSB Bancorp health plan prior to the time that such Continuing Employee becomes eligible to participate in the Northfield Bank health plan, no coverage of any of the Continuing Employees or their dependents shall terminate under any of the VSB Bancorp health plans prior to the time such Continuing Employees and their dependents become eligible to participate in the health plans, programs and benefits common to all employees of Northfield Bank and their dependents and, consequently, no Continuing Employee shall experience a gap in coverage. Northfield Bancorp and Northfield Bank shall use commercially reasonable efforts to cause each such plan to (i) waive any preexisting condition limitations to the extent such conditions are covered under the applicable health plans of Northfield Bancorp or Northfield Bank, (ii) provide full credit under such plans for any deductible, co-payment, and out-of-pocket expenses incurred by the employees and their beneficiaries during the portion of the plan year prior to participation, and (iii) waive any waiting period limitation or evidence of insurability requirement which would otherwise be applicable to the employee on or after the Effective Time, in each case to the extent the employee had satisfied any similar limitation or requirement under an analogous plan prior to the Effective Time for the plan year in which the Effective Time occurs. In the event of a termination or consolidation of any VSB Bancorp health plan, terminated VSB Bancorp and Victory Bank employees and qualified beneficiaries will have the right to continued coverage under group health plans of Northfield Bank in accordance with COBRA.

7.6.5 Northfield Bancorp and Northfield Bank agree to take all such actions related to the VSB Bancorp 401(k) Plan and VSB Bancorp ESOP as stated in Section 6.12 of this Agreement to the extent that further action is necessary following the Closing.

7.6.6 Effective as of the Closing Date and subject to the Closing, Northfield Bancorp shall establish an advisory board, which will be comprised of those persons who serve on the VSB Bancorp Board of Directors (other than the VSB Chairman of the Board but including the Chief Executive Officer of VSB Bancorp, provided he does not accept employment with Northfield Bancorp or Northfield Bank or his participation on the advisory board does not present a conflict of interest under applicable law, regulations or existing bank policies or criteria) (the “VSB Advisory Board”). Northfield Bancorp anticipates that the VSB Bancorp Advisory Board would remain for a period of not less than two (2) years following the Effective Time of the Merger. Northfield Bank will call and hold quarterly meetings, either in person or by conference call, of the VSB Bancorp Advisory Board. Each member of the VSB Bancorp Advisory Board will receive a fee of $3,000 for each meeting attended in person or by conference call, and will be expected to enter into a customary advisory board agreement, which will contain non-competition and non-solicitation provisions.

7.6.7 Effective as of the Closing Date and subject to the Closing, VSB Bancorp’s Chairman of the Board shall be offered a consulting and advisory contract, with a three-year term, at an annual fee of one hundred twenty thousand dollars ($120,000).

7.7. Directors and Officers Indemnification and Insurance.

7.7.1. Northfield Bancorp shall maintain, or shall cause Northfield Bank to maintain, in effect for six (6) years following the Effective Time, the current directors’ and officers’ liability insurance policies maintained by VSB Bancorp (provided, that Northfield Bancorp may substitute therefor policies of at least the same coverage containing terms and conditions that are not materially less favorable) with respect to matters occurring prior to the Effective Time; provided, however, that in no event shall Northfield Bancorp be required to expend pursuant to this Section 7.7.1, in the aggregate for such policy or policies, more than two-hundred percent (200%) of the annual cost currently expended by VSB Bancorp with respect to such insurance (the “Maximum Amount”); provided, further, that if the amount of the annual premiums necessary to maintain or procure such insurance coverage exceeds the Maximum Amount, Northfield Bancorp shall maintain the most advantageous policies of directors’ and officers’ insurance obtainable for an annual premium equal to the

A-48

TABLE OF CONTENTS

Maximum Amount. In connection with the foregoing, VSB Bancorp agrees in order for Northfield Bancorp to fulfill its agreement to provide directors’ and officers’ liability insurance policies for six years, to provide such insurer or substitute insurer with such representations as such insurer may request with respect to the reporting of any prior claims.

7.7.2. For a period of six (6) years after the Effective Time, Northfield Bancorp shall indemnify, defend and hold harmless each person who is now, or who has been at any time before the date hereof or who becomes before the Effective Time, an officer, director or employee of VSB Bancorp or a VSB Bancorp Subsidiary (the “Indemnified Parties”) against all losses, claims, damages, costs, expenses (including attorneys’ fees), liabilities or judgments or amounts that are paid in settlement (which settlement shall require the prior written consent of Northfield Bancorp, which consent shall not be unreasonably withheld, conditioned or delayed) of or in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, or administrative (each a “Claim”), in which an Indemnified Party is, or is threatened to be made, a party or witness in whole or in part on or arising in whole or in part out of the fact that such person is or was a director, officer or employee of VSB Bancorp or a VSB Bancorp Subsidiary if such Claim pertains to any matter of fact arising, existing or occurring before the Effective Time (including, without limitation, the Merger and the other transactions contemplated hereby), regardless of whether such Claim is asserted or claimed before, or after, the Effective Time (the “Indemnified Liabilities”), to the fullest extent as would have been permitted by VSB Bancorp under the New York Business Corporation Law and under VSB Bancorp’s certificate of incorporation and bylaws, to the extent not prohibited by Delaware or federal law or regulation. Northfield Bancorp shall pay expenses in advance of the final disposition of any such action or proceeding to each Indemnified Party to the fullest extent permitted by Delaware law (and to the extent not prohibited by federal law or regulation) upon receipt of an undertaking to repay such advance payments if the Indemnified Party shall be adjudicated or determined to be not entitled to indemnification in the manner set forth below. Any Indemnified Party wishing to claim indemnification under this Section 7.7.2 upon learning of any Claim, shall notify Northfield Bancorp (but the failure so to notify Northfield Bancorp shall not relieve Northfield Bancorp from any liability that it may have under this Section 7.7.2, except to the extent such failure materially prejudices Northfield Bancorp) and shall deliver to Northfield Bancorp the undertaking referred to in the previous sentence. In the event of any such Claim (whether arising before or after the Effective Time) (i) Northfield Bancorp shall have the right to assume the defense thereof (in which event the Indemnified Parties will cooperate in the defense of any such matter) and upon such assumption Northfield Bancorp shall not be liable to any Indemnified Party for any legal expenses of other counsel or any other expenses subsequently incurred by any Indemnified Party in connection with the defense thereof, except that if Northfield Bancorp elects not to assume such defense, or counsel for the Indemnified Parties reasonably advises the Indemnified Parties that there are or may be (whether or not any have yet actually arisen) issues which raise conflicts of interest between Northfield Bancorp and the Indemnified Parties, the Indemnified Parties may retain counsel reasonably satisfactory to them, and Northfield Bancorp shall pay the reasonable fees and expenses of such counsel for the Indemnified Parties, (ii) except to the extent otherwise required due to conflicts of interest, Northfield Bancorp shall be obligated pursuant to this paragraph to pay for only one firm of counsel for all Indemnified Parties and the reasonable fees and expenses of such law firm shall be paid promptly as statements are received unless there is a conflict of interest that necessitates more than one law firm, (iii) Northfield Bancorp shall not be liable for any settlement effected without its prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed), and (iv) no Indemnified Party shall be entitled to indemnification hereunder with respect to a matter as to which (x) he shall have been adjudicated in any proceeding not to have acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of VSB Bancorp or any VSB Bancorp Subsidiary, or (y) in the event that a proceeding is compromised or settled so as to impose any liability or obligation upon an Indemnified Party, if there is a determination that with respect to said matter said Indemnified Party did not act in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of VSB Bancorp or any VSB Bancorp Subsidiary.

7.7.3. The obligations of Northfield Bancorp provided under this Section 7.7 are intended to be enforceable against Northfield Bancorp directly by the Indemnified Parties and shall be binding on all respective successors and permitted assigns of Northfield Bancorp. Northfield Bancorp shall pay all reasonable costs, including attorneys’ fees, as incurred and in advance of the final disposition of any claim, action, suit, proceeding or investigation by any Indemnified Party in successfully enforcing the indemnity and other obligations provided for in this Section 7.7 to the fullest extent permitted under applicable law; provided, however such payment of

A-49

TABLE OF CONTENTS

costs shall be immediately reimbursed to Northfield Bancorp by such Indemnified Party if the Indemnified Party is not successful in enforcing the indemnity or other obligations provided for in this Section 7.7. The rights of each Indemnified Party hereunder shall be in addition to any other rights such Indemnified Party may have under applicable law.

7.7.4. Any indemnification payments made pursuant to this Section 7.7 are subject to and conditioned upon their compliance with Section 18(k) of the Federal Deposit Insurance Act (12 U.S.C. 1828(k)) and the regulations promulgated thereunder by the FDIC (12.C.F.R. Part 359).

7.8. Stock Listing.

Northfield Bancorp agrees to list on the Nasdaq (or such other national securities exchange on which the shares of the Northfield Bancorp Common Stock shall be listed as of the Closing Date), subject to official notice of issuance, the shares of Northfield Bancorp Common Stock to be issued in the Merger.

7.9. Stock and Cash Reserve.

December 20, 2019

Board of Directors
VSB Bancorp, Inc.
Victory State Bank
4142 Hylan Boulevard
Staten Island, NY 10308

Dear Board Members:

You have requested our written opinion, as to the fairness, from a financial point of view to VSB Bancorp, Inc. (“VSBN”) stockholders, of the consideration as proposed in the Agreement and Plan of Merger by and among Northfield Bancorp, Inc. (“NFBK”) and VSBN (the “Agreement”), pursuant to which Northfield Bancorp, Inc. will merge with VSB Bancorp, Inc. and Northfield Bank will merge with Victory State Bank.

Pursuant to the Agreement draft dated December 16, 2019 and discussions with NFBK’s financial advisor, NFBK will acquire VSBN in a 100% stock transaction, based upon VSBN shareholders receiving $33.26 per share. This price will be based upon a floating exchange ratio determined five (5) days prior to the closing of the transaction, within the limits of established collars based on amounts equal to five percent (5%) above and below NFBK’s 10-day simple average prior to signing of the Agreement. Outside of the collar, the exchange ratio will be $33.26 divided by NFBK’s 10-day simple average closing price on the trading day prior to signing of the Definitive Agreement. VSBN’s in-the-money option holders will receive cash for the difference between the per share cash consideration and the option exercise price.

FinPro Capital Advisors, Inc. (“FCA”), FINRA/SIPC, is a broker/dealer and an investment banking firm that provides valuation and merger advisory services to the bank and thrift industry, including appraisals and valuations of bank and thrift institutions and their securities in connection with mergers, acquisitions and other securities transactions. FCA has knowledge of and experience with the Mid-Atlantic bank and thrift market and financial institutions operating in the Mid-Atlantic region. VSBN’s Board chose FCA because of its expertise, experience and familiarity with the bank and thrift industry.

VSBN engaged FCA to provide its opinion as to the fairness, from a financial point of view, of the consideration as defined in the Agreement. FCA was not retained to structure, analyze, negotiate or perform any services outside of the scope of rendering a Fairness Opinion. FCA did not conduct due diligence on VSBN or NFBK. FCA will receive fees equal to $125,000 for rendering the fairness opinion. FCA’s fees are payable upon rendering of the fairness opinion to VSBN. Additionally, VSBN has agreed to reimburse FCA for its out-of-pocket expenses and has agreed to indemnify FCA and certain related persons against certain liabilities possibly incurred in connection with the services performed.

FinPro, Inc. (“FinPro”), FCA’s parent organization, has provided consulting services to VSBN within the past two years. The amount of compensation received from VSBN for these services is not, and has not been, material to FinPro’s annual gross revenue. FinPro has not provided services to NFBK within the past two years other than NFBK’s annual subscription to FinPro’s global webinar package. Prior to this current Fairness Opinion engagement with VSBN, FCA has not provided investment banking services to VSBN or NFBK in the past two years.

TABLE OF CONTENTS

Fairness Opinion | Page: 2

In connection with its opinion, FCA reviewed and considered, among other things:

| • | The Merger Agreement dated December 16, 2019 (the most current available to FCA);

| • | The most recent year-end audited and quarter-end public filings for each of VSBN and NFBK;

| • | Certain other public and non-public information regarding each of VSBN and NFBK, including internal financial forecasts, regarding the financial results and the condition of VSBN and NFBK;

| • | Acquisition multiples of comparable institutions;

| • | Potential investment value of VSBN’s shares;

| • | The trading and merger market for bank and thrift stocks;

| • | Relative contribution of each entity to the pro forma combined institution;

| • | The ability for NFBK to execute on the proposed transaction; and

| • | The pro forma financial impact of the transaction.

FCA considered financial studies, analyses and investigations and economic and market information that FCA deemed relevant. FCA considered certain financial data of VSBN and compared that data to other banks, thrifts and their holding companies that were recently merged or acquired. Additionally, FCA considered a range of potential investment values for VSBN’s shares on a present value basis assuming the successful execution of their projected financial forecasts.

FCA analyzed the trading values of NFBK relative to comparable financial institutions to determine that NFBK was reasonably valued in the share exchange. FCA also considered the potential pro forma financial impact of the acquisition.

FCA did not independently verify the financial data provided by or on behalf of VSBN or NFBK, but instead relied upon and assumed the accuracy and completeness of the data provided.

FCA expresses no opinion with respect to the amount or nature of any compensation to any officers, directors, or employees of any party to the transaction relative to the consideration to be paid to VSBN stockholders in the transaction or with respect to the fairness of any such compensation.

STATUTORY PROVISIONS RELATING TO DISSENTERS’ RIGHTS

§ 623. Procedure to enforce shareholder’s right to receive payment for shares

| (a) | A shareholder intending to enforce his right under a section of this chapter to receive payment for his shares if the proposed corporate action referred to therein is taken shall file with the corporation, before the meeting of shareholders at which the action is submitted to a vote, or at such meeting but before the vote, written objection to the action. The objection shall include a notice of his election to dissent, his name and residence address, the number and classes of shares as to which he dissents and a demand for payment of the fair value of his shares if the action is taken. Such objection is not required from any shareholder to whom the corporation did not give notice of such meeting in accordance with this chapter or where the proposed action is authorized by written consent of shareholders without a meeting.

| (b) | Within ten days after the shareholders’ authorization date, which term as used in this section means the date on which the shareholders’ vote authorizing such action was taken, or the date on which such consent without a meeting was obtained from the requisite shareholders, the corporation shall give written notice of such authorization or consent by registered mail to each shareholder who filed written objection or from whom written objection was not required, excepting any shareholder who voted for or consented in writing to the proposed action and who thereby is deemed to have elected not to enforce his right to receive payment for his shares.

| (c) | Within twenty days after the giving of notice to him, any shareholder from whom written objection was not required and who elects to dissent shall file with the corporation a written notice of such election, stating his name and residence address, the number and classes of shares as to which he dissents and a demand for payment of the fair value of his shares. Any shareholder who elects to dissent from a first-step merger under section 905 (First-step merger of subsidiary corporation) or paragraph (c) of section 907 (First-step merger or consolidation of domestic and foreign corporations) or from a share exchange under paragraph (g) of section 913 (Share exchanges) shall file a written notice of such election to dissent within twenty days after the giving to him of a copy of the plan of first-step merger or exchange or an outline of the material features thereof under section 905 or 913.

| (d) | A shareholder may not dissent as to less than all of the shares, as to which he has a right to dissent, held by him of record, that he owns beneficially. A nominee or fiduciary may not dissent on behalf of any beneficial owner as to less than all of the shares of such owner, as to which such nominee or fiduciary has a right to dissent, held of record by such nominee or fiduciary.

| (e) | Upon consummation of the corporate action, the shareholder shall cease to have any of the rights of a shareholder except the right to be paid the fair value of his shares and any other rights under this section. A notice of election may be withdrawn by the shareholder at any time prior to his acceptance in writing of an offer made by the corporation, as provided in paragraph (g), but in no case later than sixty days from the date of consummation of the corporate action except that if the corporation fails to make a timely offer, as provided in paragraph (g), the time for withdrawing a notice of election shall be extended until sixty days from the date an offer is made. Upon expiration of such time, withdrawal of a notice of election shall require the written consent of the corporation. In order to be effective, withdrawal of a notice of election must be accompanied by the return to the corporation of any advance payment made to the shareholder as provided in paragraph (g). If a notice of election is withdrawn, or the corporate action is rescinded, or a court shall determine that the shareholder is not entitled to receive payment for his shares, or the shareholder shall otherwise lose his dissenters’ rights, he shall not have the right to receive payment for his shares and he shall be reinstated to all his rights as a shareholder as of the consummation of the corporate action, including any intervening preemptive rights and the right to payment of any intervening dividend or other distribution or, if any such rights have expired or any such dividend or distribution other than in cash has been completed, in lieu thereof, at the election of the corporation, the fair value thereof in cash as determined by the board as of the time of such expiration or completion, but without prejudice otherwise to any corporate proceedings that may have been taken in the interim.

| (f) | At the time of filing the notice of election to dissent or within one month thereafter the shareholder of shares represented by certificates shall submit the certificates representing his shares to the corporation, or to its transfer agent, which shall forthwith note conspicuously thereon that a notice of election has been filed

C-1

TABLE OF CONTENTS

and shall return the certificates to the shareholder or other person who submitted them on his behalf. Any shareholder of shares represented by certificates who fails to submit his certificates for such notation as herein specified shall, at the option of the corporation exercised by written notice to him within forty-five days from the date of filing of such notice of election to dissent, lose his dissenter’s rights unless a court, for good cause shown, shall otherwise direct. Upon transfer of a certificate bearing such notation, each new certificate issued therefor shall bear a similar notation together with the name of the original dissenting holder of the shares and a transferee shall acquire no rights in the corporation except those which the original dissenting shareholder had at the time of transfer.

| (g) | Within fifteen days after the expiration of the period within which shareholders may file their notices of election to dissent, or within fifteen days after the proposed corporate action is consummated, whichever is later (but in no case later than ninety days from the shareholders’ authorization date), the corporation or, in the case of a first-step merger or consolidation, the surviving or new corporation, shall make a written offer by registered mail to each shareholder who has filed such notice of election to pay for his shares at a specified price which the corporation considers to be their fair value. Such offer shall be accompanied by a statement setting forth the aggregate number of shares with respect to which notices of election to dissent have been received and the aggregate number of holders of such shares. If the corporate action has been consummated, such offer shall also be accompanied by (1) advance payment to each such shareholder who has submitted the certificates representing his shares to the corporation, as provided in paragraph (f), of an amount equal to eighty percent of the amount of such offer, or (2) as to each shareholder who has not yet submitted his certificates a statement that advance payment to him of an amount equal to eighty percent of the amount of such offer will be made by the corporation promptly upon submission of his certificates. If the corporate action has not been consummated at the time of the making of the offer, such advance payment or statement as to advance payment shall be sent to each shareholder entitled thereto forthwith upon consummation of the corporate action. Every advance payment or statement as to advance payment shall include advice to the shareholder to the effect that acceptance of such payment does not constitute a waiver of any dissenters’ rights. If the corporate action has not been consummated upon the expiration of the ninety day period after the shareholders’ authorization date, the offer may be conditioned upon the consummation of such action. Such offer shall be made at the same price per share to all dissenting shareholders of the same class, or if divided into series, of the same series and shall be accompanied by a balance sheet of the corporation whose shares the dissenting shareholder holds as of the latest available date, which shall not be earlier than twelve months before the making of such offer, and a profit and loss statement or statements for not less than a twelve month period ended on the date of such balance sheet or, if the corporation was not in existence throughout such twelve month period, for the portion thereof during which it was in existence. Notwithstanding the foregoing, the corporation shall not be required to furnish a balance sheet or profit and loss statement or statements to any shareholder to whom such balance sheet or profit and loss statement or statements were previously furnished, nor if in connection with obtaining the shareholders’ authorization for or consent to the proposed corporate action the shareholders were furnished with a proxy or information statement, which included financial statements, pursuant to Regulation 14A or Regulation 14C of the United States Securities and Exchange Commission. If within thirty days after the making of such offer, the corporation making the offer and any shareholder agree upon the price to be paid for his shares, payment therefor shall be made within sixty days after the making of such offer or the consummation of the proposed corporate action, whichever is later, upon the surrender of the certificates for any such shares represented by certificates.

| (h) | The following procedure shall apply if the corporation fails to make such offer within such period of fifteen days, or if it makes the offer and any dissenting shareholder or shareholders fail to agree with it within the period of thirty days thereafter upon the price to be paid for their shares:

| (1) | The corporation shall, within twenty days after the expiration of whichever is applicable of the two periods last mentioned, institute a special proceeding in the supreme court in the judicial district in which the office of the corporation is located to determine the rights of dissenting shareholders and to fix the fair value of their shares. If, in the case of first-step merger or consolidation, the surviving or new corporation is a foreign corporation without an office in this state, such proceeding shall be brought in the county where the office of the domestic corporation, whose shares are to be valued, was located.

C-2

TABLE OF CONTENTS

| (2) | If the corporation fails to institute such proceeding within such period of twenty days, any dissenting shareholder may institute such proceeding for the same purpose not later than thirty days after the expiration of such twenty day period. If such proceeding is not instituted within such thirty day period, all dissenter’s rights shall be lost unless the supreme court, for good cause shown, shall otherwise direct.

| (3) | All dissenting shareholders, excepting those who, as provided in paragraph (g), have agreed with the corporation upon the price to be paid for their shares, shall be made parties to such proceeding, which shall have the effect of an action quasi in rem against their shares. The corporation shall serve a copy of the petition in such proceeding upon each dissenting shareholder who is a resident of this state in the manner provided by law for the service of a summons, and upon each nonresident dissenting shareholder either by registered mail and publication, or in such other manner as is permitted by law. The jurisdiction of the court shall be plenary and exclusive.

| (4) | The court shall determine whether each dissenting shareholder, as to whom the corporation requests the court to make such determination, is entitled to receive payment for his shares. If the corporation does not request any such determination or if the court finds that any dissenting shareholder is so entitled, it shall proceed to fix the value of the shares, which, for the purposes of this section, shall be the fair value as of the close of business on the day prior to the shareholders’ authorization date. In fixing the fair value of the shares, the court shall consider the nature of the transaction giving rise to the shareholder’s right to receive payment for shares and its effects on the corporation and its shareholders, the concepts and methods then customary in the relevant securities and financial markets for determining fair value of shares of a corporation engaging in a similar transaction under comparable circumstances and all other relevant factors. The court shall determine the fair value of the shares without a jury and without referral to an appraiser or referee. Upon application by the corporation or by any shareholder who is a party to the proceeding, the court may, in its discretion, permit pretrial disclosure, including, but not limited to, disclosure of any expert’s reports relating to the fair value of the shares whether or not intended for use at the trial in the proceeding and notwithstanding subdivision (d) of section 3101 of the civil practice law and rules.

| (5) | The final order in the proceeding shall be entered against the corporation in favor of each dissenting shareholder who is a party to the proceeding and is entitled thereto for the value of his shares so determined.

| (6) | The final order shall include an allowance for interest at such rate as the court finds to be equitable, from the date the corporate action was consummated to the date of payment. In determining the rate of interest, the court shall consider all relevant factors, including the rate of interest which the corporation would have had to pay to borrow money during the pendency of the proceeding. If the court finds that the refusal of any shareholder to accept the corporate offer of payment for his shares was arbitrary, vexatious or otherwise not in good faith, no interest shall be allowed to him.

| (7) | Each party to such proceeding shall bear its own costs and expenses, including the fees and expenses of its counsel and of any experts employed by it. Notwithstanding the foregoing, the court may, in its discretion, apportion and assess all or any part of the costs, expenses and fees incurred by the corporation against any or all of the dissenting shareholders who are parties to the proceeding, including any who have withdrawn their notices of election as provided in paragraph (e), if the court finds that their refusal to accept the corporate offer was arbitrary, vexatious or otherwise not in good faith. The court may, in its discretion, apportion and assess all or any part of the costs, expenses and fees incurred by any or all of the dissenting shareholders who are parties to the proceeding against the corporation if the court finds any of the following: (A) that the fair value of the shares as determined materially exceeds the amount which the corporation offered to pay; (B) that no offer or required advance payment was made by the corporation; (C) that the corporation failed to institute the special proceeding within the period specified therefor; or (D) that the action of the corporation in complying with its obligations as provided in this section was arbitrary, vexatious or otherwise not in good faith. In making any determination as provided in clause (A), the court may consider the dollar amount or the percentage, or both, by which the fair value of the shares as determined exceeds the corporate offer.

C-3

TABLE OF CONTENTS

| (8) | Within sixty days after final determination of the proceeding, the corporation shall pay to each dissenting shareholder the amount found to be due him, upon surrender of the certificates for any such shares represented by certificates.

| (i) | Shares acquired by the corporation upon the payment of the agreed value therefor or of the amount due under the final order, as provided in this section, shall become treasury shares or be cancelled as provided in section 515 (Reacquired shares), except that, in the case of a first-step merger or consolidation, they may be held and disposed of as the plan of first-step merger or consolidation may otherwise provide.

| (j) | No payment shall be made to a dissenting shareholder under this section at a time when the corporation is insolvent or when such payment would make it insolvent. In such event, the dissenting shareholder shall, at his option:

| (1) | Withdraw his notice of election, which shall in such event be deemed withdrawn with the written consent of the corporation; or

| (2) | Retain his status as a claimant against the corporation and, if it is liquidated, be subordinated to the rights of creditors of the corporation, but have rights superior to the non-dissenting shareholders, and if it is not liquidated, retain his right to be paid for his shares, which right the corporation shall be obliged to satisfy when the restrictions of this paragraph do not apply.

| (3) | The dissenting shareholder shall exercise such option under subparagraph (1) or (2) by written notice filed with the corporation within thirty days after the corporation has given him written notice that payment for his shares cannot be made because of the restrictions of this paragraph. If the dissenting shareholder fails to exercise such option as provided, the corporation shall exercise the option by written notice given to him within twenty days after the expiration of such period of thirty days.

| (k) | The enforcement by a shareholder of his right to receive payment for his shares in the manner provided herein shall exclude the enforcement by such shareholder of any other right to which he might otherwise be entitled by virtue of share ownership, except as provided in paragraph (e), and except that this section shall not exclude the right of such shareholder to bring or maintain an appropriate action to obtain relief on the ground that such corporate action will be or is unlawful or fraudulent as to him.

| (l) | Except as otherwise expressly provided in this section, any notice to be given by a corporation to a shareholder under this section shall be given in the manner provided in section 605 (Notice of meetings of shareholders).

| (m) | This section shall not apply to foreign corporations except as provided in subparagraph (e)(2) of section 907 (First-step merger or consolidation of domestic and foreign corporations).

§ 910. Right of shareholder to receive payment for shares upon first-step merger or consolidation, or sale, lease, exchange or other disposition of assets, or share exchange

| (a) | A shareholder of a domestic corporation shall, subject to and by complying with section 623 (Procedure to enforce shareholder’s right to receive payment for shares), have the right to receive payment of the fair value of his shares and the other rights and benefits provided by such section, in the following cases:

| (1) | Any shareholder entitled to vote who does not assent to the taking of an action specified in clauses (A), (B) and (C).

| (A) | Any plan of first-step merger or consolidation to which the corporation is a party; except that the right to receive payment of the fair value of his shares shall not be available:

| (i) | To a shareholder of the parent corporation in a first-step merger authorized by section 905 (First-step merger of parent and subsidiary corporations), or paragraph (c) of section 907 (First-step merger or consolidation of domestic and foreign corporations); or

| (ii) | To a shareholder of the surviving corporation in a first-step merger authorized by this article, other than a first-step merger specified in subclause (i), unless such first-step merger effects one or more of the changes specified in subparagraph (b) (6) of section 806 (Provisions as to certain proceedings) in the rights of the shares held by such shareholder; or

| (iii) | Notwithstanding subclause (ii) of this clause, to a shareholder for the shares of any class or series of stock, which shares or depository receipts in respect thereof, at the record date fixed to determine the shareholders entitled to receive notice of the meeting of shareholders to vote upon the plan of first-step merger or consolidation, were listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc.

| (B) | Any sale, lease, exchange or other disposition of all or substantially all of the assets of a corporation which requires shareholder approval under section 909 (Sale, lease, exchange or other disposition of assets) other than a transaction wholly for cash where the shareholders’ approval thereof is conditioned upon the dissolution of the corporation and the distribution of substantially all of its net assets to the shareholders in accordance with their respective interests within one year after the date of such transaction.

| (C) | Any share exchange authorized by section 913 in which the corporation is participating as a subject corporation; except that the right to receive payment of the fair value of his shares shall not be available to a shareholder whose shares have not been acquired in the exchange or to a shareholder for the shares of any class or series of stock, which shares or depository receipt in respect thereof, at the record date fixed to determine the shareholders entitled to receive notice of the meeting of shareholders to vote upon the plan of exchange, were listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

| Item 20. | Indemnification of Directors and Officers

Under a directors’ and officers’ liability insurance policy, directors and officers of the Corporation are insured against certain liabilities.

Section 145 of the Delaware General Corporation Law provides for indemnification of officers and directors as follows:

(a) A corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person's conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that the person's conduct was unlawful.

(b) A corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys' fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

(c) To the extent that a present or former director or officer of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections (a) and (b) of this section, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by such person in connection therewith.

(d) Any indemnification under subsections (a) and (b) of this section (unless ordered by a court) shall be made by the corporation only as authorized in the specific case upon a determination that indemnification of the present or former director, officer, employee or agent is proper in the circumstances because the person has met the applicable standard of conduct set forth in subsections (a) and (b) of this section. Such determination shall be made, with respect to a person who is a director or officer of the corporation at the time of such determination:

| (1) | By a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum;  or

| (2) | By a committee of such directors designated by majority vote of such directors, even though less than a quorum;  or

| (3) | If there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion;  or

II-1

TABLE OF CONTENTS

| (4) | By the stockholders.

(e) Expenses (including attorneys' fees) incurred by an officer or director of the corporation in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the corporation as authorized in this section. Such expenses (including attorneys' fees) incurred by former directors and officers or other employees and agents of the corporation or by persons serving at the request of the corporation as directors, officers, employees or agents of another corporation, partnership, joint venture, trust or other enterprise may be so paid upon such terms and conditions, if any, as the corporation deems appropriate.

(f) The indemnification and advancement of expenses provided by, or granted pursuant to, the other subsections of this section shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person's official capacity and as to action in another capacity while holding such office. A right to indemnification or to advancement of expenses arising under a provision of the certificate of incorporation or a bylaw shall not be eliminated or impaired by an amendment to the certificate of incorporation or the bylaws after the occurrence of the act or omission that is the subject of the civil, criminal, administrative or investigative action, suit or proceeding for which indemnification or advancement of expenses is sought, unless the provision in effect at the time of such act or omission explicitly authorizes such elimination or impairment after such action or omission has occurred.

(g) A corporation shall have power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person's status as such, whether or not the corporation would have the power to indemnify such person against such liability under this section.

(h) For purposes of this section, references to “the corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, and employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under this section with respect to the resulting or surviving corporation as such person would have with respect to such constituent corporation if its separate existence had continued.

(i) For purposes of this section, references to “other enterprises” shall include employee benefit plans;  references to “fines” shall include any excise taxes assessed on a person with respect to any employee benefit plan;  and references to “serving at the request of the corporation” shall include any service as a director, officer, employee or agent of the corporation which imposes duties on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries;  and a person who acted in good faith and in a manner such person reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the corporation” as referred to in this section.

(j) The indemnification and advancement of expenses provided by, or granted pursuant to, this section shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.

(k) The Court of Chancery is hereby vested with exclusive jurisdiction to hear and determine all actions for advancement of expenses or indemnification brought under this section or under any bylaw, agreement, vote of stockholders or disinterested directors, or otherwise. The Court of Chancery may summarily determine a corporation's obligation to advance expenses (including attorneys' fees).

TABLE OF CONTENTS

Articles NINTH and TENTH of the Certificate of Incorporation of Northfield Bancorp, Inc. (the “Corporation”) sets forth circumstances under which directors, officers, employees and agents of the Corporation may be insured or indemnified against liability which they incur in their capacities as such:

NINTH:

A. Each person who was or is made a party or is threatened to be made a party to or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “proceeding”), by reason of the fact that he or she is or was a Director or an Officer of the Corporation or is or was serving at the request of the Corporation as a Director, Officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan (hereinafter an “indemnitee”), whether the basis of such proceeding is alleged action in an official capacity as a Director, Officer, employee or agent or in any other capacity while serving as a Director, Officer, employee or agent, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the Delaware General Corporation Law, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than such law permitted the Corporation to provide prior to such amendment), against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such indemnitee in connection therewith; provided, however, that, except as provided in Section C hereof with respect to proceedings to enforce rights to indemnification, the Corporation shall indemnify any such indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized by the Board of Directors of the Corporation.

B. The right to indemnification conferred in Section A of this Article NINTH shall include the right to be paid by the Corporation the expenses incurred in defending any such proceeding in advance of its final disposition (hereinafter an “advancement of expenses”); provided, however, that, if the Delaware General Corporation Law requires an advancement of expenses incurred by an indemnitee in his or her capacity as a Director of Officer (and not in any other capacity in which service was or is rendered by such indemnitee, including, without limitation, service to an employee benefit plan) shall be made only upon delivery to the Corporation of an undertaking (hereinafter an “undertaking”), by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal (hereinafter a “final adjudication”) that such indemnitee is not entitled to be indemnified for such expenses under this Section or otherwise. The rights to indemnification and to the advancement of expenses conferred in Sections A and B of this Article NINTH shall be contract rights and such rights shall continue as to an indemnitee who has ceased to be a Director, Officer, employee or agent and shall inure to the benefit of the indemnitee’s heirs, executors and administrators.

C. If a claim under Section A or B of this Article NINTH is not paid in full by the Corporation within sixty days after a written claim has been received by the Corporation, except in the case of a claim for an advancement of expenses, in which case the applicable period shall be twenty days, the indemnitee may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, or in a suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the indemnitee also shall be entitled to be paid the expense of prosecuting or defending such suit. In (i) any suit brought by the indemnitee to enforce a right to indemnification hereunder (but not in a suit brought by the indemnitee to enforce a right to an advancement of expenses) it shall be a defense that, and (ii) in any suit by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking the Corporation shall be entitled to recover such expenses upon a final adjudication that, the indemnitee has not met any applicable standard for indemnification set forth in the Delaware General Corporation Law. Neither the failure of the Corporation (including its Board of Directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such suit that indemnification of the indemnitee is proper in the circumstances because the indemnitee has met the applicable standard of conduct set forth in the Delaware General Corporation Law, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel, or its stockholders) that the indemnitee has not met such applicable standard of conduct, shall create a presumption that the indemnitee has not met the applicable standard of conduct or, in the case of such a suit brought by the indemnitee, be a defense to such suit. In any suit brought by the indemnitee to enforce a right to indemnification or to an advancement of expenses

TABLE OF CONTENTS

hereunder, or by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the burden of proving that the indemnitee is not entitled to be indemnified, or to such advancement of expenses, under this Article NINTH or otherwise shall be on the Corporation.

D. The rights to indemnification and to the advancement of expenses conferred in this Article NINTH shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, the Corporation’s Certificate of Incorporation, Bylaws, agreement, vote of stockholders or disinterested Directors or otherwise.

E. The Corporation may maintain insurance, at its expense, to protect itself and any Director, Officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the Delaware General Corporation Law.

F. The Corporation may, to the extent authorized from time to time by the Board of Directors, grant rights to indemnification and to the advancement of expenses to any employee or agent of the Corporation to the fullest extent of the provisions of this Article NINTH with respect to the indemnification and advancement of expenses of Directors and Officers of the Corporation.

TENTH: A Director of this Corporation shall not be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a Director, except for liability (i) for any breach of the Director’s duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the Delaware General Corporation Law, or (iv) for any transaction from which the Director derived an improper personal benefit.

| Item 22. | Undertakings

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement; (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; (iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

TABLE OF CONTENTS

(c)(1) The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

(2) The registrant undertakes that every prospectus (i) that is filed pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet the requirements of section 10(a)(3) of the Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(d) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(e) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of, and included in the registration statement when it became effective.

(f) Insofar as indemnification for liabilities arising under the Securities Act of 1933 (the “Act”) may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act, and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
