AS REPRESENTATIVE OF THE SEVERAL AGENTS

1251 Avenue of the Americas, 6^th Floor

New York, New York 10022

Ladies and Gentlemen:

Northfield Bancorp, Inc., a Delaware corporation (the “Company”), Northfield Bancorp, Inc., a federal “mid-tier” holding company (the “Mid-Tier Company”), Northfield Bancorp, MHC, a federal mutual holding company (the “MHC”), and Northfield Bank, a federally chartered stock savings bank (the “Bank”), hereby confirm their agreement with Sandler O’Neill & Partners, L.P. (“Sandler O’Neill”) as representative of the several Agents (as defined below) (in such capacity, the “Representative”), Jefferies & Company, Inc. (“Jefferies”) and Stifel, Nicolaus & Company, Incorporated (“Stifel Nicolaus” and together with Sandler O’Neill and Jefferies, the “Agents”), with respect to the offer and sale by the Company of up to 41,975,000 shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”). The shares of Common Stock to be sold by the Company in the Offerings (as defined below) are hereinafter called the “Securities.”

The Securities are being offered for sale in accordance with the Plan of Conversion and Reorganization (the “Plan”) adopted by the Boards of Directors of the Mid-Tier Company and the Bank and the Board of Trustees of the MHC pursuant to which the MHC intends to convert from the mutual to stock holding company form of organization pursuant to the following steps: (i) the establishment of the Company as a Delaware-chartered subsidiary of the Mid-Tier Company; (ii) the merger of the MHC with and into the Mid-Tier Company with the Mid-Tier

Company as the surviving entity (the “MHC Merger”); (iii) the merger of the Mid-Tier Company with and into the Company with the Company as the surviving entity (the “Mid-Tier Company Merger”); and (iv) the sale and exchange of Common Stock pursuant to the Plan. As a result of the MHC Merger and the Mid-Tier Company Merger, the Bank will become a wholly owned subsidiary of the Company. The outstanding shares of common stock of the Mid-Tier Company held by persons other than the MHC will be converted into Common Stock pursuant to an exchange ratio as defined in the Plan, which will result in the holders of such shares receiving and owning in the aggregate approximately the same percentage of the Common Stock to be outstanding upon the completion of the conversion as the percentage of Mid-Tier Company common stock owned by them in the aggregate immediately prior to consummation of the conversion before giving effect to (a) cash paid in lieu of any fractional interests of Common Stock and (b) any Securities purchased in the Offerings. The Company will sell and exchange the Common Stock pursuant to the Plan and regulations of the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”).

Pursuant to the Plan, the Company will offer to certain depositors of the Bank and to the Bank’s tax qualified employee benefit plans, including the Bank’s employee stock ownership plan (the “ESOP”) and 401(k) Savings Plan (collectively, the “Employee Plans”), rights to subscribe for the Securities in a subscription offering (the “Subscription Offering”). To the extent Securities are not subscribed for in the Subscription Offering, such Securities may be offered to certain members of the general public in a community offering (the “Community Offering”), with preference given first to persons who are natural persons and trusts of natural persons who are residents of the New Jersey Counties of Bergen, Essex, Hudson, Hunterdon, Middlesex, Monmouth, Morris, Ocean, Passaic, Somerset, Sussex and Union, the New York Counties of Bronx, Kings, Nassau, New York, Putnam, Queens, Richmond, Rockland, Suffolk and Westchester, and Pike County, Pennsylvania, second to shareholders of the Mid-Tier Company as of the voting record date and finally to other members of the general public. The Community Offering, which together with the Subscription Offering, as each may be extended or reopened from time to time, are herein referred to as the “Subscription and Community Offering,” may be commenced concurrently with, during or after, the Subscription Offering. It is currently anticipated that any Securities not subscribed for in the Subscription and Community Offering will be offered, subject to Section 2 hereof, in a syndicated offering (the “Syndicated Offering”) or an underwritten public offering (the “Public Offering”); provided, however, that the Community Offering may occur concurrently with the Subscription Offering and the Syndicated Offering or the Public Offering. The Subscription and Community Offering, the Syndicated Offering and the Public Offering are hereinafter referred to collectively as the “Offerings.” The conversion and reorganization of the MHC from mutual to stock holding company form, the formation of the Company, the MHC Merger, the Mid-Tier Company Merger, the exchange of the Mid-Tier Company’s public stockholders’ shares for shares of Common Stock (the “Exchange Shares”), the acquisition of the capital stock of the Bank by the Company and the Offerings are hereinafter referred to collectively as the “Conversion.” It is acknowledged that the number of Securities to be sold in the Conversion may be increased or decreased as described in the Prospectus (as hereinafter defined). If the number of Securities is increased or decreased in accordance with the Plan, the term “Securities” shall mean such greater or lesser number, where applicable. If there is a Public Offering, the Public Offering will be governed by a separate Underwriting Agreement, as hereinafter defined, as described in Section 2 hereof.

The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-1 (No. 333-181995), including a related prospectus, for the registration of the sale of the Securities under the Securities Act of 1933, as amended (the “Securities Act”), has filed such amendments thereto, if any, and such amended prospectuses as may have been required to the date hereof by the Commission in order to declare such registration statement effective, and will file such additional amendments thereto and such amended prospectuses and prospectus supplements as may hereafter be required. Such registration statement (as amended to date, if applicable, and as from time to time amended or supplemented hereafter) including post-effective amendments thereto containing the preliminary and final prospectus for the Public Offering, if any (the “Registration Statement”), and the prospectuses constituting a part thereof (including in each case all documents incorporated or deemed to be incorporated by reference therein and the information, if any, deemed to be a part thereof pursuant to the rules and regulations of the Commission promulgated under the Securities Act, as from time to time amended or supplemented pursuant to the Securities Act or otherwise (the “Securities Act Regulations”)) as well as the preliminary prospectus, if any, as defined in Rule 430A under the Securities Act Regulations and the prospectus for the Public Offering, if any, contained in a post-effective amendment to the Registration Statement), are hereinafter referred to as the “Registration Statement” and the “Prospectus,” respectively, except that if any revised prospectus shall be used by the Company in connection with the Subscription and Community Offering, the Syndicated Offering or the Public Offering, if any, which differs from the Prospectus on file at the Commission at the time the Registration Statement becomes effective (whether or not such revised prospectus is required to be filed by the Company pursuant to Rule 424(b) of the Securities Act Regulations), the term “Prospectus” shall refer to such revised prospectus from and after the time it is first provided to the Agents for such use.

Concurrently with the execution of this Agreement, the Company is delivering to the Representative copies of the Prospectus of the Company to be used in the Subscription and Community Offering and, if necessary, will deliver copies of the Prospectus and a prospectus supplement for use in a Syndicated Offering or Public Offering, if any. Such Prospectus contains information with respect to the Bank, the Mid-Tier Company, the Company, the MHC and the Common Stock.

(ii) At the time of filing the Registration Statement relating to the offering of the Securities and as of the date hereof, the Company was not, and is not, an ineligible issuer, as defined in Securities Act Rule 405. At the time of the filing of the Registration Statement and at the time of the use of any issuer free writing prospectus, as defined in Securities Act Rule 433(h), the Company met the conditions required by Securities Act Rules 164 and 433 for the use of a free writing prospectus. If required to be filed, the Company has filed any issuer free writing prospectus related to the Securities at the time it is required to be filed under Securities Act Rule 433 and, if not required to be filed, will retain such free writing prospectus in the Company’s records pursuant to Securities Act Rule 433(g) and if any issuer free writing prospectus is used after the date hereof in connection with the offering of the Securities, the Company will file or retain such free writing prospectus as required by Securities Act Rule 433.

(iii) As of the Applicable Time, neither (i) the Issuer-Represented General Free Writing Prospectus(es) issued at or prior to the Applicable Time and the Statutory Prospectus, all considered together (collectively, the “General Disclosure Package”), nor (ii) any individual Issuer-Represented Limited-Use Free Writing Prospectus, when considered together with the General Disclosure Package, included any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from any Prospectus included in the Registration Statement relating to the Securities or any Issuer-Represented Free Writing Prospectus based upon and in conformity with written information furnished to the Company by the Agents specifically for use therein. As used in this paragraph and elsewhere in this Agreement:

1. “Applicable Time” means each and every date when a potential purchaser submitted a subscription or otherwise committed to purchase Securities.

4. “Issuer-Represented General Free Writing Prospectus” means any Issuer-Represented Free Writing Prospectus that is intended for general distribution to prospective investors.

5. “Issuer-Represented Limited-Use Free Writing Prospectus” means any Issuer-Represented Free Writing Prospectus that is not an Issuer-Represented General Free Writing Prospectus.

(iv) Each Issuer-Represented Free Writing Prospectus, as of its date of first use and at all subsequent times through the completion of the Offerings and sale of the Securities or until any earlier date that the Company notified or notifies the Agents (as described in the next sentence), did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement relating to the Securities, including any document incorporated by reference therein that has not been superseded or modified. If at any time following the date of first use of an Issuer-Represented Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer-Represented Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement relating to the Securities or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company has notified or will notify promptly the Agents so that any use of such Issuer-Represented Free-Writing Prospectus may cease until it is amended or supplemented and the Company has promptly amended or will promptly amend or supplement such Issuer-Represented Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

and the Bank as set forth in Sections 4, 6(a) and 7 hereof and the obligations of the Agents as provided in Sections 6(b) and 7 hereof.

The hour and date upon which the Company shall release for delivery all of the Securities, in accordance with the terms hereof, is herein called the “Closing Time.”

SECTION 6. INDEMNIFICATION.

(i) from and against any and all loss, liability, claim, damage and expense whatsoever, as incurred, related to or arising out of the Conversion or any action taken by the Agents where acting as agents of the Company, the Mid-Tier Company, the MHC or the Bank or otherwise as described in Section 2 hereof;

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

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

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

provided, however, that the indemnification provided for in this paragraph (a) shall not apply to any loss, liability, claim, damage or expense that (i) arises out of any untrue statement or alleged untrue statement of a material fact contained in the Prospectus or the General Disclosure Package or any Issuer-Represented Free Writing Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading which was made in reliance upon and in conformity with the Agent Information, or (ii) is primarily attributable to the gross negligence, willful misconduct or bad faith of the Agents. To the extent required by law, the indemnification provided for in this paragraph (a) shall be subject to and limited by Section 23A of the Federal Reserve Act, as amended.

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

(c) Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability that it may have otherwise than on account of this indemnity agreement. An indemnifying party may participate at its own expense in the defense of any such action. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to no more than one local counsel in each separate jurisdiction in which any action or proceeding is commenced) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances.

(d) The Company, the Mid-Tier Company, the MHC and the Bank also agree that the Agents shall not have any liability (whether direct or indirect, in contract or tort or otherwise) to the MHC, the Mid-Tier Company and its security holders, the Company and its security holders or the MHC’s, the Mid-Tier Company’s, the Bank’s or the Company’s creditors relating to or

arising out of the engagement of the Agents pursuant to, or the performance by the Agents of the services contemplated by, this Agreement, except to the extent that any liability is found in a final judgment by a court of competent jurisdiction to have resulted primarily from the Agents’ bad faith, willful misconduct or gross negligence.

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

SECTION 7. CONTRIBUTION. In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in Section 6 hereof is for any reason held to be unenforceable by the indemnified parties although applicable in accordance with its terms, the Company, the Mid-Tier Company, the MHC, the Bank, and the Agents shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by the Company, the Mid-Tier Company, the MHC or the Bank and the Agents, as incurred, in such proportions (i) that the Agents are responsible for that portion represented by the percentage that the maximum aggregate marketing fees appearing on the cover page of the Prospectus bears to the maximum aggregate gross proceeds appearing thereon and the Company, the Mid-Tier Company, the MHC and the Bank are jointly and severally responsible for the balance or (ii) if, but only if, the allocation provided for in clause (i) is for any reason held unenforceable, in such proportion as is appropriate to reflect not only the relative benefits to the Company, the Mid-Tier Company, the MHC and the Bank on the one hand and the Agents on the other, as reflected in clause (i), but also the relative fault of the Company, the Mid-Tier Company, the MHC and the Bank on the one hand and the Agents on the other, as well as any other relevant equitable considerations; provided, however, that no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section, each person, if any, who controls the Agents within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Agents, and each director of the Company, the Mid-Tier Company, the MHC and the Bank, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company, the Mid-Tier Company, the MHC or the Bank within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company, the Mid-Tier Company, the MHC and the Bank.

The Shares are being sold in accordance with the Plan of Conversion and Reorganization (the “Plan”) adopted by the Boards of Directors of Northfield Bancorp, Inc., a federal “mid-tier” holding company (the “Mid-Tier Company”) and Northfield Bank, a federally chartered stock savings bank (the “Bank”) and the Board of Trustees of Northfield Bancorp, MHC, a federal mutual holding company (the “MHC”), pursuant to which the MHC intends to convert from the mutual to stock holding company form of organization pursuant to the following steps: (i) the establishment of the Company as a Delaware-chartered subsidiary of the Mid-Tier Company; (ii) the merger of the MHC with and into the Mid-Tier Company with the Mid-Tier Company as the surviving entity (the “MHC Merger”); (iii) the merger of the Mid-Tier Company with and into

the Company with the Company as the surviving entity (the “Mid-Tier Company Merger”); and (iv) the sale and exchange of Common Stock pursuant to the Plan.

In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in Section 6 hereof is for any reason held to be unenforceable by the indemnified parties although applicable in accordance with its terms, the Company, the Mid-Tier Company, the MHC, the Bank, and the Representatives shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by the Company, the Mid-Tier Company, the MHC or the Bank and the Underwriters, as incurred, in such proportions (i) that the Underwriters are responsible for that portion represented by the percentage that the total net proceeds from the Public Offering of the Shares (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each as set forth in the table on the cover page of the Prospectus and the Company, the Mid-Tier Company, the MHC and the Bank are jointly and severally responsible for the balance or (ii) if, but only if, the allocation provided for in clause (i) is for any reason held unenforceable, in such proportion as is appropriate to reflect not only the relative benefits to the Company, the Mid-Tier Company, the MHC and the Bank on the one hand and the Underwriters on the other, as reflected in clause (i), but also the relative fault of the Company, the Mid-Tier Company, the MHC and the Bank on the one hand and the Underwriters on the other, as well as any other relevant equitable considerations; provided, however, that no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section, each person, if any, who controls the Underwriters within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Underwriters, and each director of the Company, the Mid-Tier Company, the MHC and the Bank, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company, the Mid-Tier Company, the MHC or the Bank within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company, the Mid-Tier Company, the MHC and the Bank. Notwithstanding anything to the contrary set forth herein, to the extent permitted by applicable law, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

Bank submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of the Underwriter or controlling person, or by or on behalf of the Company, and shall survive delivery of the Shares.

SECTION 9. DEFAULT BY UNDERWRITERS.

(a) If any Underwriter shall default in its obligation to purchase the Shares which it has agreed to purchase hereunder at a Time of Delivery, the Representatives may in their discretion arrange for them or another party or other parties to purchase such Shares on the terms contained herein. If within thirty six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Shares, then the Company shall be entitled to a further period of thirty six hours within which to procure another party or other parties satisfactory to the Representatives to purchase such Shares on such terms. In the event that, within the respective prescribed periods, the Representatives notify the Company that they have so arranged for the purchase of such Shares, or the Company notifies the Representatives that it has so arranged for the purchase of such Shares, the Representatives or the Company shall have the right to postpone such Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments to the Registration Statement or the Prospectus which in the Representatives’ opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in Section 7(a), the aggregate number of such Shares which remains unpurchased does not exceed one tenth of the aggregate number of all the Shares to be purchased at such Time of Delivery, then the Company shall have the right to require each non defaulting Underwriter to purchase the number of shares which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided in Section 9(a) hereof, the aggregate number of such Shares which remains unpurchased exceeds one tenth of the aggregate number of all the Shares to be purchased at such Time of Delivery, or if the Company shall not exercise the right described in Section 9(b) hereof to require non defaulting Underwriters to purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the indemnity and contribution agreements in Sections 6 and 7 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(d) If this Agreement is terminated pursuant to Section 9(c) hereof, none of the Company, the Mid-Tier Company, the MHC or the Bank shall then be under any liability to any Underwriter except as provided in Sections 6 and 7 hereof; but, if this Agreement is terminated pursuant to Section 5 or for any other reason, any Shares are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters for all out-of-pocket expenses, including fees and disbursements of counsel, incurred by the Underwriters in connection with the transactions contemplated hereby, including, without limitation, marketing, syndication and travel expenses incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Shares not so delivered, but the Company shall then be under no further liability to any Underwriter except as provided in Sections 4 and 7 hereof.

SECTION 10. TERMINATION OF AGREEMENT.

(a) The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to the Time of Delivery (i) if there has been, since the date of this Agreement or since the respective dates as of which information is given in the Registration Statement, any Material Adverse Effect, whether or not arising in the ordinary course of business, (ii) if there has occurred any material adverse change in the financial markets in the United States or elsewhere or any outbreak of hostilities or escalation thereof or other calamity or crisis the effect of which, in the judgment of the Representatives, are so material and adverse as to make it impracticable to market the Shares or to enforce contracts, including subscriptions or orders, for the sale of the Shares, (iii) if trading generally on the Nasdaq Global Select Market, the American Stock Exchange or the New York Stock Exchange has been suspended, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices for securities have been required, by any of said Exchanges or by order of the Commission or any other governmental authority, or if a banking moratorium has been declared by either Federal, New Jersey or New York authorities, (iv) if any condition specified in Section 5 hereof shall not have been fulfilled when and as required to be fulfilled; (v) if there shall have been such material adverse change in the condition or prospects of the Company, the Mid-Tier Company, the MHC or the Bank or the prospective market for the Company’s Securities as in the Representatives’ good faith opinion would make it inadvisable to proceed with the offering, sale or delivery of the Shares; (vi) if, in the Representatives’ good faith opinion, the price for the Securities established by the Appraiser is not reasonable or equitable under then prevailing market conditions, or (vii) if the Conversion is not consummated on or prior to June 30, 2013.

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

SECTION 11. NOTICES. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

At the Time of Delivery, the Representatives shall have received:

The favorable opinion, dated as of the Date of Delivery, of Luse Gorman Pomerenk & Schick, P.C., counsel for the Company, the Mid-Tier Company, the MHC and the Bank acceptable to Representatives in form and substance satisfactory to counsel for Representatives to the effect that:

(v) The Securities, including the Shares, have been duly authorized for issuance and sale; the Exchange Shares have been duly authorized for issuance; the Securities, when issued and delivered by the Company pursuant to the Plan against payment of the consideration calculated as set forth in the Plan, will be validly issued and fully paid and nonassessable; the Exchange Shares, when issued and delivered by the Company pursuant to the Plan, will be validly issued and fully paid and nonassessable.

The execution and delivery of this Agreement and the Agency Agreement and the consummation of the transactions contemplated hereby and thereby, (A) have been duly authorized by all necessary action on the part of each of the Company, the Mid-Tier Company, the MHC and the Bank, (B) will not violate the articles of incorporation, charter or bylaws of the Company, the Mid-Tier Company, the MHC or the Bank, and (C) will not result in a breach of or default, or result in the creation of any lien, charge or encumbrance under any agreement filed as an exhibit to the Registration Statement.

(xiii) Each of the Agreement and the Agency Agreement constitutes a legal, valid and binding agreement of each of the Company, the Mid-Tier Company, the MHC and the Bank, enforceable in accordance with its respective terms, except as rights to indemnity and contribution thereunder may be limited under applicable law, and subject to the qualification that (i) enforcement thereof may be limited by bankruptcy, insolvency, moratorium, reorganization or other laws (including the laws of fraudulent conveyance) or judicial decisions affecting the enforceability of creditors’ rights generally or the rights of creditors of savings banks or financial institutions, the accounts of which are insured by the FDIC, and (ii) enforcement thereof is subject to general equity principles (regardless of whether such enforceability is considered in a proceeding in equity or at law) and to the effect of certain laws and judicial decisions upon the availability of injunctive relief and enforceability of equitable remedies, including the remedies of specific performance and self-help.

(xiv) The Registration Statement, including any post-effective amendment thereto, has been declared effective by the Commission under the Securities Act, and such counsel has been advised by the Commission’s staff that no stop order suspending the effectiveness of the Registration Statement has been issued under the Securities Act and that no proceedings for such purpose have been initiated or, to such counsel’s actual knowledge, threatened by the Commission.

(xv) No further approval, authorization, consent or other order of any public board or body is required in connection with the execution and delivery of the Agreement, the Agency Agreement, the issuance of the Securities, including the Shares and the Exchange Shares and the consummation of the Conversion except as may be required under the securities or Blue Sky laws of various jurisdictions as to which no opinion need be rendered.

A-4

(xvi) At the time the Registration Statement, including any post-effective amendment thereto, became effective, the Registration Statement complied as to form in all material respects with the requirements of the Securities Act and the Securities Act Regulations; it being understood, however, that (i) no opinion need be rendered with respect to the financial statements, the notes thereto, or other tabular, financial, statistical and appraisal data included in, or omitted from, the Registration Statement and (ii) in passing upon the compliance as to form of the Registration Statement, such counsel may assume that the statements made therein are correct and complete, except as otherwise set forth in paragraph (xxi).

(xvii) The Common Stock conforms to the description thereof contained in the Prospectus, and the form of certificate used to evidence the Common Stock complies with all applicable statutory requirements.

(xviii) To such counsel’s actual knowledge, there are no legal or governmental proceedings pending or threatened against or affecting the Company, the Mid-Tier Company, the MHC or the Bank that are required, individually or in the aggregate, to be disclosed in the Registration Statement and Prospectus, other than those disclosed therein.

(xix) The information in the Prospectus under “Taxation,” “Supervision and Regulation,” “The Conversion and Offering—Share Exchange Ratio for Current Stockholders,” “—Effects of Conversion on Depositors, Borrowers and Members,” “—Liquidation Rights,” “—Certain Restrictions on Purchase or Transfer of Our Shares after Conversion,” “—Restrictions on Transfer of Subscription Rights and Shares,” and “—Material Income Tax Consequences,” “Comparison of Stockholders’ Rights For Existing Stockholders of Northfield Bancorp, Inc.,” “Restrictions on Acquisition of Northfield-Delaware,” and “Description of Capital Stock of Northfield-Delaware Following the Conversion,” to the extent that it constitutes matters of law, summaries of legal matters, documents or proceedings, or legal conclusions, has been reviewed by them and is complete and accurate in all material respects.

(xx) To such counsel’s actual knowledge, there are no contracts, indentures, mortgages, loan agreements, notes, leases or other instruments required to be described or referred to in the Registration Statement and Prospectus or to be filed as exhibits thereto other than those described or referred to therein or filed as exhibits thereto and the descriptions thereof or references thereto are correct, and, except as described in the Prospectus, no default exists, and no event has occurred which, with notice or lapse of time or both, would constitute a default, in the due performance or observance of any material obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, loan agreement, note, lease or other instrument so described, referred to or filed.

A-5

(xxi) The Plan has been duly authorized by the Boards of Directors of the Company, the Mid-Tier Company, and the Bank and the Board of Trustees of the MHC, and the Plan has been approved by the requisite vote of the MHC’s members and of the Mid-Tier Company’s stockholders.

(xxii) To such counsel’s actual knowledge, the Company, the Mid-Tier Company, the MHC and the Bank have conducted the Conversion in accordance with applicable requirements of the FRB Regulations, (except to the extent that the requirement to comply was specifically waived by the Federal Reserve Board), the Plan and the letter from the Federal Reserve Board dated approving the Holding Company Application and Conversion Application (which letters, to such counsel’s actual knowledge, are the only such letters received from the Federal Reserve Board relating to the approval of the Holding Company Application and the Conversion Application), and have satisfied all conditions precedent to the Conversion imposed upon the Company, the Mid-Tier Company, the MHC or the Bank by the Federal Reserve Board and no order has been issued by the Federal Reserve Board to suspend the Conversion or the Offerings and no action for such purpose has been instituted or threatened by the Federal Reserve Board; and to such counsel’s actual knowledge no person has sought to obtain review of the final action of the Federal Reserve Board in approving the Plan, the Conversion Application or the Holding Company Application.

(xxiii) To such counsel’s actual knowledge, neither the Company, the Mid-Tier Company, the MHC nor the Bank is currently in violation of their respective articles of incorporation, charters or bylaws.

(xxiv) The Company is not and, upon completion of the Conversion and the Offerings and the sale of the Common Stock and the application of the net proceeds therefrom, will not be required to be registered as an investment company under the Investment Company Act of 1940.

(xxv) Each Subsidiary is validly existing as a corporation chartered under its respective jurisdiction of incorporation with corporate power and authority to own its properties and conduct its business as described in the Prospectus. All of the issued and outstanding capital stock of each Subsidiary is owned beneficially and of record by the Bank free and clear of any security interest, mortgage, pledge, lien or encumbrance. The activities of each Subsidiary as described in the Prospectus are permitted for subsidiaries of federally chartered savings banks.

In giving their opinions, Luse Gorman Pomerenk & Schick, P.C. may rely as to matters of fact on certificates of officers and directors of the Company, the Mid-Tier Company, the MHC and the Bank and certificates of public officials.

The undersigned understands that Sandler O’Neill & Partners, L.P. (“Sandler O’Neill”), as representative of the several Agents (as defined below), Jefferies & Company, Inc. (“Jefferies”) and Stifel, Nicolaus & Company, Incorporated (“Stifel Nicolaus” and together with Sandler O’Neill and Jefferies, the “Agents”), proposes to enter into an Agency Agreement (the “Agency Agreement”) with Northfield Bancorp, Inc., a Delaware corporation (the “Company”), Northfield Bancorp, Inc., a federally-chartered stock holding company (the “Mid-Tier”), Northfield Bancorp, MHC, a federally-chartered mutual holding company (the “MHC”) and Northfield Bank, a federally-chartered stock savings bank (the “Bank” and, together with the Company, the Mid-Tier and the MHC, the “Northfield Parties”), providing for the public offering (the “Public Offering”) by the Representatives, of up to 41,975,000 shares (the “Shares”) of the Company’s common stock, par value $0.01 per share (the “Stock”).

In recognition of the benefit that the Public Offering will confer upon the undersigned, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with Sandler O’Neill that, during the period beginning on the date of the final prospectus relating to the subscription offering (the “Subscription Offering Prospectus”) and ending 90 days after the Closing Date of the Public Offering (the “Restricted Period”), the undersigned will not, without the prior written consent of Sandler O’Neill, directly or indirectly, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any shares of the Company’s Stock, the common stock of Mid-Tier (“Mid-Tier Stock”) or any securities convertible into or exchangeable or exercisable for Stock or Mid-Tier Stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition, or file any registration statement under the Securities Act of 1933, as amended, with respect to any of the foregoing, (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Stock or Mid-Tier Stock, whether any such swap or transaction is to be settled by delivery of Stock, Mid-Tier Stock or other securities, in cash or otherwise or (iii) publicly announce an intention to do any of the foregoing.

The Company shall promptly notify Sandler O’Neill of any earnings releases, news or events that may give rise to an extension of the Restricted Period.

Notwithstanding the foregoing, the undersigned may transfer the undersigned’s shares of Stock and Mid-Tier Stock (i) as a bona fide gift or gifts, provided that the donee or donees agree to be bound in writing by the restrictions set forth herein, (ii) to any trust or family limited partnership for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust or general partner of the family limited partnership, as the case may be, agrees to be bound by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, (iii) pledged in a bona fide transaction outstanding as of the date hereof to a lender to the undersigned, as disclosed in writing to Sandler O’Neill, (iv) pursuant to the exercise by the undersigned of stock options that have been granted by the Mid-Tier Company prior to, and are outstanding as of, the date of the Agency Agreement, where the Stock or Mid-Tier Stock received upon any such exercise is held by the undersigned, individually or as fiduciary, in accordance with the terms of this Lock-Up Agreement, (v) the withholding of Stock or Mid-Tier Stock to satisfy tax withholding obligations upon the vesting of restricted stock, or (vi) with the prior written consent of Sandler O’Neill.

In furtherance of the foregoing, the Company and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Agreement.

The undersigned represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Agreement. The undersigned understands that the Company and Sandler O’Neill are relying upon this Lock-Up Agreement in proceeding toward consummation of the Public Offering.

Sandler O’Neill & Partners, L.P.

1251 Avenue of the Americas, 6^th Floor

New York, New York 10020

Ladies and Gentlemen:

In connection with offerings of securities after the date hereof for which Sandler O’Neill & Partners, L.P. (“Sandler O’Neill” or “you”) is acting as manager of an underwriting syndicate or is otherwise responsible for the distribution of securities by means of an offering of securities for sale to selected dealers (“Selected Dealers”), we may be offered the right to purchase as principal a portion of the securities being distributed; the offering of Securities is hereinafter called the “Offering.” This will confirm our mutual agreement as to the general terms and conditions applicable to our participation in any such selected dealer group organized by Sandler O’Neill as follows:

1. Applicability of this Agreement. The terms and conditions of this Agreement shall be applicable to any offering of securities (“Securities”) wherein Sandler O’Neill (acting for its own account or for the account of any underwriting or similar group or syndicate) is responsible for managing or otherwise implementing the sale of the Securities to Selected Dealers and has expressly informed us that such terms and conditions shall be applicable. In the case of any Offering in which you are acting for the account of any underwriting or similar group or syndicate (“Underwriters”), the terms and conditions of this Agreement shall be for the benefit of, and binding upon, such Underwriters, including, in the case of any Offering in which you are acting with others as representative of the Underwriters, such other representatives. The term “preliminary prospectus” means any preliminary prospectus, together with any preliminary prospectus supplement, relating to an Offering of Securities; the term “Prospectus” means the prospectus, together with the final prospectus supplement, if any, relating to the Offering of Securities.

2. Conditions of Offering; Acceptance and Purchases. The Offering will be subject to delivery of the Securities and their acceptance by you and any other Underwriters, may be subject to the approval of all legal matters by counsel and the satisfaction of other conditions, and may be made on the basis of reservation of Securities or an allotment against subscription. You will advise us by telegram, telex, facsimile or other form of written communication (“Written Communication,” which term may include a prospectus) of the particular method and supplementary terms and conditions (including, without limitation, the information as to prices and offering date referred to in Section 3(b) hereof) of any Offering in which we are invited to participate and the applicability of the general terms of this Agreement. To the extent such supplementary terms and conditions are inconsistent with any provision herein, such terms and conditions shall supersede any such provision. Unless otherwise indicated in any such Written Communication, acceptances and other communications to us with respect to any Offering should be sent to Sandler O’Neill & Partners, L.P., 1251 Avenue of the Americas., 6th Floor, New York, New York 10020 Attention: Syndicate Department. We reserve the right in our discretion to reject any acceptance in whole or in part, and to allot.

C-1

Payment for Securities purchased by us shall be made at the offices of Sandler O’Neill, 1251 Avenue of Americas., 6th Floor, New York, New York 10020, at the Offering Price (as hereinafter defined), or, if you shall advise us, at such price less the Concession to dealers (as hereinafter defined) or at the price set forth or indicated in a Written Communication, on such date as you shall determine, on one day’s prior notice to us, payable in New York Clearing House funds against delivery of the Securities. If Securities are purchased and paid for at such Offering Price, such Concession will be paid after the termination of the provisions of Section 3(b) hereof with respect to such Securities. Notwithstanding the foregoing, unless we give you written instructions otherwise, if transactions in the Securities may be settled through the facilities of The Depository Trust Company, payment for and delivery of Securities purchased by us will be made through such facilities if we are a member, or, if we are not a member, settlement may be made through our correspondent who is a member in same day funds pursuant to instructions which we will send to you prior to such specified date.

3. Representations, Warranties and Agreements.

(a) Use of Prospectus or Offering Circular. You shall provide us with such number of copies of each preliminary prospectus, the Prospectus and any supplement thereto relating to each Offering as we may reasonably request for the purposes contemplated by the Securities Act of 1933, as amended (the “Securities Act”) and the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the applicable rules and regulations of the Securities and Exchange Commission thereunder. We represent and warrant that we are familiar with Rule 15c2-8 under the Exchange Act relating to the distribution of preliminary and final prospectuses and agree that we will comply therewith. With respect to Securities for which no Registration Statement is filed with the Securities and Exchange Commission (the “Commission”), you will furnish to us, to the extent made available to you by the issuer, copies of any private placement memorandum, offering circular or other offering materials to be used in connection with the offering of the Securities and of each amendment thereto (the “Offering Circular”). We agree to keep an accurate record of our distribution (including dates, number of copies and persons to whom sent) of any preliminary prospectus (or any amendment or supplement to any thereof), and, promptly upon request by you, to bring all subsequent changes to the attention of anyone to whom such material shall have been furnished. We agree that in purchasing Securities in the Offering we will rely upon no statement whatsoever, written or oral, other than the statements in the final prospectus or Offering Circular, as applicable, delivered to us by you. We will not be authorized by the issuer or other seller of Securities offered pursuant to a prospectus or Offering Circular or by any Underwriters to give any information or to make any representation not contained in the Prospectus or Offering Circular in connection with the sale of the Securities.

(b) Offer and Sale. With respect to any Offering of Securities, you will inform us by a Written Communication of the offering price, the selling concession, the reallowance (if any) to dealers and the time when we may commence selling Securities. After such offering has commenced, you may change the offering price, the selling concession and the reallowance to dealers. The offering price, selling concession and reallowance (if any) to dealers at any time in effect with respect to the Offering are hereinafter referred to, respectively, as the “Offering Price,” the “Concession” and the “Reallowance.” With respect to the Offering, until the provisions of this Section 3(b) shall be terminated pursuant to Section 4 hereof, we agree to offer Securities only at the Offering Price, except that if a Reallowance is in effect, a reallowance from the Offering Price not in excess of such Reallowance may be allowed as consideration for services rendered in distribution to dealers who are actually engaged in the investment banking or securities business, who execute the written agreement prescribed by Rule 2740(c) of the Conduct Rules of the Financial Industry Regulatory Authority (the “FINRA”) and who are either members in good standing of the FINRA or foreign banks, dealers or institutions not eligible for

C-2

membership in the FINRA who represent to us that they will promptly reoffer such Securities at the Offering Price and will abide by the conditions with respect to foreign banks, dealers and institutions set forth in Section 3(e) hereof.

(c) Over-allotment; Stabilization; Unsold Allotments. You may, with respect to any Offering, be authorized to over-allot in arranging sales to Selected Dealers, to purchase and sell Securities, any other securities of the issuer of the Securities of the same class and series and any other securities of such issuer that you may designate for long or short account and to stabilize or maintain the market price of the Securities. We agree to advise you at any time and from time to time upon your request, prior to the termination of the provisions of Section 3(b) hereof, of the amount of Securities purchased by us pursuant to the Offering which then remain unsold by us, and we will, upon your request at any such time, sell to you for your account or the account of one or more of the Underwriters, such amount of such unsold Securities as you may designate, at the Offering Price less an amount to be determined by you not in excess of the Concession. In the event that prior to the later of (a) the termination of the provisions of Section 3(b) hereof with respect to any Offering, or (b) the covering by you of any short position created by you in connection with such Offering for your account or the account of one or more Underwriters, you purchase or contract to purchase for your account or the account of one or more Underwriters, in the open market or otherwise, any Securities theretofore delivered to us, you reserve the right to withhold the above-mentioned Concession on such Securities if sold to us at the Offering Price, or if such Concession has been allowed to us through our purchase at a net price, we agree to repay such Concession upon your demand, plus, in each case, any taxes on redelivery, commissions, dealer’s mark-up, accrued interest and dividends, if any, paid in connection with such purchase or contract to purchase.

(d) Open Market Transaction. Until such time as the terms of this Agreement shall no longer apply to an Offering or until you notify us that we are released from this restriction, we agree not to deal, trade, bid for, purchase, attempt to purchase, or sell, directly or indirectly, any Securities, any other securities of the issuer of the Securities of the same class and series or any other securities of such issuer as you may designate, except as brokers pursuant to unsolicited orders and as otherwise provided in this Agreement. If the Securities are common stock or securities convertible into common stock, we agree not to effect, or attempt to induce others to effect, directly or indirectly, any transactions in or relating to put or call options on any stock of such issuer or warrants to purchase such stock, except to the extent permitted by Regulation M upon its effectiveness under the Exchange Act as interpreted by the Commission.

(e) FINRA. We represent and warrant that we are actually engaged in the investment banking or securities business and we are either a member in good standing of the FINRA or, if not such a member, a foreign bank, dealer or institution not eligible for membership in the FINRA. If we are such a member, we agree that in making sales of the Securities we will comply with all applicable rules of the FINRA, including, without limitation, Rule 2740 and 2790 of the FINRA’s Conduct Rules. If we are such a foreign bank, dealer or institution, we agree not to offer or sell any Securities in the United States, its territories or its possessions or to persons who are citizens thereof or residents therein except through you and in making sales of Securities outside the United States we agree to comply as though we were a member with Rules 2730, 2740, 2750 and 2790 of the FINRA’s Conduct Rules and to comply with Rule 2420 as it applies to nonmember brokers or dealers in a foreign country. We further represent, by our participation in the Offering, that we have provided to you all documents and other information required to be filed with respect to us, any related person or any person associated with us or any such related person pursuant to the supplementary requirements of the FINRA’s interpretation with respect to review of corporate financing as such requirements relate to the Offering.

C-3

(f) Relationship Among Underwriters and Selected Dealers. You may buy Securities from or sell Securities to any Underwriter or Selected Dealer and, with your consent, the Underwriters (if any) and the Selected Dealers may purchase Securities from and sell Securities to each other at the Offering Price less all or any part of the Concession. We are not authorized to act as agents for you, any Underwriter or the issuer or other seller or any guarantor of any Securities in offering Securities to the public or otherwise. Nothing contained herein or in any Written Communication from you shall constitute the Selected Dealers an association or partners with you or any Underwriter or with one another. We shall not be under any obligation to you except for obligations expressly assumed hereby or in any Written Communication from you in connection with the Offering.

(g) Blue Sky Laws. Upon application to you, you shall inform us as to the jurisdictions in which you believe the Securities have been qualified for sale or are exempt under the securities or “blue sky” laws of such jurisdictions. We understand and agree that compliance with the securities or “blue sky” laws in each jurisdiction in which we shall offer or sell any of the Securities shall be our sole responsibility and that you assume no responsibility or obligation as to the eligibility of the Securities for sale or our right to sell the Securities in any jurisdiction.

(h) Compliance with Law. We agree that in selling Securities pursuant to the Offering (which agreement shall also be for the benefit of the issuer or other seller of such Securities) we will comply with all applicable laws, rules and regulations, including the applicable provisions of the Securities Act and the Exchange Act, the applicable rules and regulations of the Commission thereunder, the applicable rules and regulations of the FINRA and the applicable rules and regulations of any securities exchange having jurisdiction over the Offering. You shall have full authority to take such action as you may deem advisable in respect of all matters pertaining to any Offering. Neither you nor any Underwriter shall be under any liability to us, except for lack of good faith and for obligations expressly assumed by you in this Agreement; provided, however, that nothing in this sentence shall be deemed to relieve you from any liability imposed by the Securities Act.

4. Termination; Supplements and Amendments. This Agreement may be terminated by either party hereto upon five business days’ written notice to the other party; provided, however, that with respect to any Offering for which a Written Communication was sent and accepted prior to such notice, this Agreement, as it applies to such Offering and all previous offerings, shall terminate in accordance with the last sentence of this Section. This Agreement may be supplemented or amended by you by written notice thereof to us, and any such supplement or amendment to this Agreement shall be effective with respect to any Offering to which this Agreement applies after the date of such supplement or amendment. Each reference to “this Agreement” herein shall, as appropriate, be to this Agreement as so amended or supplemented. The terms and conditions set forth in Section 3(b) and (d) with regard to any Offering will terminate at the close of business on the thirtieth day after the effective date of the registration statement pursuant to which such Offering is made, but in your discretion such terms and conditions upon notice to us, may be extended by you for a further period not exceeding thirty days and, whether or not extended, may be terminated by you at any time.

5. Successors and Assigns. This Agreement shall be binding on, and inure to the benefit of, the parties hereto and other persons specified in Sections 1 and 3(h) hereof, and the respective successors and assigns of each of them.

6. Governing Law. This Agreement and the terms and conditions set forth herein, together with the supplementary terms and conditions with respect to the Offering as may be contained in any Written Communication from you to us in connection therewith, shall be governed by, and construed in accordance with, the laws of the State of New York, without giving effect to its conflicts of laws principles.

C-4

7. Certain Tax Matters. If the Selected Dealers, among themselves or with the Underwriters, are deemed to constitute a partnership for Federal income tax purposes, then we elect to be excluded from the application of Subchapter K, Chapter 1, Subtitle A of the Internal Revenue Code of 1986, as amended, and agree not to take any position inconsistent with that election. You are hereby authorized, in your discretion, to execute and file on our behalf such evidence of this election as may be required by the Internal Revenue Service. In connection with the Offering, we shall be liable for your proportionate amount of any tax, claim, demand or liability that may be asserted against us alone or against one or more Selected Dealers participating in such Offering, or against you or the Underwriters, based upon the claim that the Selected Dealers, or any of them, constitute an association, an unincorporated business or other entity, including, in each case, our proportionate amount of any expense incurred in defending against any such tax, claim demand or liability.

C-5

By signing this Agreement we confirm that our subscription to, or our acceptance of any reservation of, any Securities pursuant to an Offering shall constitute (i) acceptance of and agreement to the terms and conditions of this Agreement (as supplemented or amended pursuant to Section 4), together with and subject to any supplementary terms and conditions contained in any Written Communication from you in connection with such Offering, all of which shall constitute a binding agreement between us and you, individually or as representative of any Underwriters, (ii) confirmation that our representations and warranties set forth in Section 3 hereof are true and correct at that time, (iii) confirmation that our agreements set forth in Sections 2 and 3 hereof have been and will be fully performed by us to the extent and at the times required thereby and (iv) acknowledgment that we have requested and received from you sufficient copies of the final prospectus with respect to such Offering in order to comply with our undertakings in Section 3(a) hereof.
