Re:  Certain Federal Income Tax Consequences Relating to Proposed Holding 
     Company Conversion
     --------------------------------------------------------------------

Gentlemen:

     In accordance with your request, set forth hereinbelow is the opinion of 
this firm relating to certain federal income tax consequences of the proposed 
conversion of Northfield Federal Savings (the "Association") from a federally 
chartered mutual savings association to federally chartered capital stock 
savings bank with the name "Northfield Federal Savings Bank" (the "Converted 
Bank") and the concurrent acquisition of 100% of the outstanding capital stock 
of the Converted Bank by Northfield Bancorp, Inc. (the "Company"), a Maryland 
corporation formed at the direction of the Board of Directors of the Association
to become the parent holding company of the Converted Bank (the "Conversion").

     For purposes of this opinion, we have examined such documents and questions
of law as we have considered necessary or appropriate, including but not limited
to the Plan of Conversion as adopted on December 17, 1997 by the Board of 
Directors of the Association (the "Plan"); the federal mutual charter and bylaws
of the Association, as amended; the federal stock charter and bylaws of the 
Converted Bank; the articles of incorporation and bylaws of the Company; the 
Affidavit of Representations dated _________, 1998 provided to us by the 
Association (the "Affidavit"), and the Prospectus (the "Prospectus") included in
the Company's Registration

Statement on Form SB-2 filed with the Securities and Exchange Commission ("SEC")
in connection with the Conversion on March __, 1998 (the "Registration 
Statement"). In such examination, we have assumed, and have not independently 
verified, the genuineness of all signatures on original documents where due 
execution and delivery are requirements to the effectiveness thereof. Terms used
but not defined herein, whether capitalized or not, shall have the same meaning
as defined in the Plan.


                                  BACKGROUND
                                  ----------

     Based solely upon our review of such documents, and upon such information 
as the Association has provided to us (which we have not attempted to verify in 
any respect), and in reliance upon such documents and information, we set forth 
hereinbelow a general summary of the relevant facts and proposed transaction, 
qualified in its entirety by reference to the documents cited above.

     The Association is a federally chartered mutual savings association, which 
is in the process of converting to a federally chartered capital stock savings 
bank. The Association was organized as a federally chartered mutual savings 
institution in 1923.

     The Association is a member of the FHLB System, and the deposits of the 
Association are insured by the Federal Deposit Insurance Corporation ("FDIC") up
to applicable limits. The Association is subject to comprehensive regulation and
supervision by the Office of Thrift Supervision ("OTS") and to examination by 
the OTS. The Association operates two offices in Baltimore County, Maryland.

     The Association's principal business consists of attracting deposits,
primarily certificates of deposit, from the general public and originating 
residential mortgage loans, primarily construction/permanent loans on one- to 
four-family properties. The Association also offers commercial real estate and 
limited types of consumer loans. The Association also has a portfolio of 
purchased commercial leases. At December 31, 1997, the Association had total 
assets of $36.1 million, deposits of $32.6 million and retained earnings of $2.9
million.

     As a federally chartered mutual savings association, the Association has no
authorized capital stock. Instead, the Association, in mutual form, has a unique
equity structure. A savings

depositor of the Association is entitled to payment of interest on his account 
balance as declared and paid by the Association, but has no right to a 
distribution of any earnings of the Association except for interest paid on his 
deposit. Rather, such earnings become retained income of the Association.

     However, a savings depositor does have a right to share pro rata, with 
                                                             --- ----
respect to the withdrawal value of his respective savings account, in any 
liquidation proceeds distributed if the Association is ever liquidated. 
Further, savings depositors and borrowers are members of the Association and 
thereby have voting rights in the Association. Under the Association's federal 
mutual charter, each depositor is entitled to cast one vote for each $100 or
fraction thereof held in a withdrawable deposit account of the Association, and
each borrower member (hereinafter "borrower") is entitled to one vote in
addition to the votes (if any) to which such person is entitled in such
borrower's capacity as a savings depositor of the Association. Also under such
federal mutual charter, no member is entitled to cast more than 1,000 votes. All
of the interests held by a savings depositor in the Association cease when such
depositor closes his accounts with the Association.

     The Company was incorporated on March 5, 1998 under the laws of the State 
of Maryland to act as the savings and loan holding company of the Converted Bank
upon consummation of the Conversion. Prior to consummation of the Conversion,
the Company has not been engaged in and is not expected to engage in any
material operations. After the Conversion, the Company's principal business will
be overseeing the business of the Converted Bank. The Company has authorized
capital stock of $8,000,000 shares of common stock (the "Common Stock"), par
value $.01 per share, and 2,000,000 shares of serial preferred stock, par value
$.01 per share.

                             PROPOSED TRANSACTION
                             --------------------

     The Board of Directors of the Association has decided that in order to 
attract new capital to the Converted Bank to increase its net worth, to support 
future savings growth, to increase the amount of funds available for lending 
and investment, to provide greater resources for the expansion of customer 
services, and to facilitate future expansion, it would be advantageous for the
Association to convert from a federally chartered mutual savings association to
a federally chartered capital stock savings bank. In addition, the Board of
Directors intends to implement stock option plans and other stock benefit plans
following the Conversion in order to better attract

and retain qualified directors and officers. It is the further desire of the 
Board of Directors to reorganize the Converted Bank as the wholly owned 
subsidiary of the Company to enhance flexibility of operations, diversification 
of business opportunities and financial capability for business and regulatory
purposes and to enable the Converted Bank to compete more effectively with other
financial service organizations.

     Accordingly, pursuant to the Plan, the Association will undergo the
Conversion whereby it will be converted from a federally chartered mutual 
savings association to a federally chartered capital stock savings bank. The
Converted Bank will then issue to the Company 100,000 shares of the Converted
Bank's common stock, representing all of the shares of capital stock to be
issued by the Converted Bank in the conversion, and the Company will make
payment to the Converted Bank in an amount equal to at least 50% of the
aggregate net proceeds realized by the Company from the sale of its Common Stock
sold pursuant to the Plan, after deducting the amount necessary to fund a loan
to an Employee Stock Ownership Plan being established in connection with the
Conversion, or such other portion of the aggregate net proceeds as may be
authorized or required by the OTS. Pursuant to the Prospectus, the Company
currently anticipates making such payment to the Converted Bank of an amount
equal to 50% of the aggregate net proceeds from the sale of the Common Stock.

     Also pursuant to the Plan, the Company will offer its shares of Common 
Stock for sale in a Subscription Offering. Shares of Common Stock remaining, if 
any, may then be offered to the general public in a Community Offering. Shares 
of the Common Stock not otherwise subscribed for in the Subscription Offering
and Community Offering may be offered at the discretion of the Company to
certain members of the general public as part of a community offering on a best
efforts basis by a selling group of selected broker-dealers.

     The purchase price per share and total number of shares of Common Stock to 
be offered and sold pursuant to the Plan will be determined by the Boards of 
Directors of the Association and the Company, on the basis of the estimated pro
                                                                            ---
forma market value of the Converted Bank, as a subsidiary of the Company, which 
- -----
will in turn be determined by an independent appraiser. The aggregate purchase
price for all shares of the Common Stock will be equal to such estimated pro
                                                                         ---
forma market value. Pursuant to the Plan, all such shares of Common Stock will

be issued and sold at a uniform price per share. The Conversion, including the
sale of newly issued shares of

the stock of the Converted Bank to the Company, will be deemed effective 
concurrently with the closing of the sale of the Common Stock.

     Under the Plan and in accordance with regulations of the OTS, the shares of
Common Stock will first be offered through the Subscription Offering pursuant to
non-transferable subscription rights on the basis of preference categories in
the following order of priority:

     (1)  Eligible Account Holders;

     (2)  Tax-Qualified Employee Stock Benefit Plans (i.e. the ESOP);

     (3)  Supplemental Eligible Account Holders; and

     (4)  Other Members.            

     However, any shares of Common Stock sold in excess of the high-end of the
Valuation Range may first be sold to Tax-Qualified Employee Stock Benefit Plans
set forth in category (2) above.

     Any shares of Common Stock not subscribed for in the Subscription Offering 
will be offered in the Community Offering in the following order of priority:

     (a)  Natural persons and trusts of natural persons (including individual
          retirement and Keogh retirement accounts and personal trusts in which
          such natural persons have substantial interests) who are permanent
          Residents of the Association's Local Community, Baltimore County,
          Maryland; and

     (b)  The general public.

     Shares not sold in the Subscription Offering and the Community Offering, if
any, may thereafter be offered for sale to certain members of the general public
as part of a community offering on a best efforts basis by a selling group of
selected broker-dealers. The sale of shares in the Subscription Offering,
Community Offering, and as sold through the selected broker-dealers would be
consummated at the same time.

 
Board of Directors

     The Plan also provides for the establishment of a Liquidation Account by 
the Converted Bank for the benefit of all Eligible Account Holders and 
Supplemental Eligible Account Holders in an amount equal to the regulatory
capital of the Association as of the date of the latest statement of financial
condition contained in the final prospectus issued in connection with the
Conversion. The establishment of the Liquidation Account will not operate to
restrict the use or application of any of the net worth accounts of the
Converted Bank, except that the Converted Bank may not declare or pay cash
dividends on or repurchase any of its stock if the result thereof would be to
reduce its regulatory capital below the amount required to maintain the
Liquidation Account. All such account holders will have an inchoate interest in
a proportionate amount of the Liquidation Account with respect to each savings
account held and will be paid by the Converted Bank in event of liquidation
prior to any liquidating distribution being made with respect to capital stock.
Under the Plan, the Conversion shall not be deemed to be a liquidation of the
Association for purposes of distribution of the Liquidation Account. Instead,
upon consummation of the Conversion, the Liquidation Account, together with the
related rights and obligations of the Converted Bank, shall be assumed by the
Converted Bank.

     The Conversion will not interrupt the business of the Association. The 
Converted Bank will, after the Conversion, engage in the same business as that 
of the Association immediately prior to the Conversion, and will continue to 
be subject to regulation and supervision by the OTS. Further, the deposits of 
the Converted Bank will continue to be insured by the FDIC. Each depositor 
will retain a withdrawable savings account or accounts equal in dollar amount 
to, and on the same terms and conditions as, the withdrawable account or 
accounts at the time of Conversion except to the extent funds on deposit are 
used to pay for Common Stock purchased in connection with the Conversion. All 
loans of the Association will remain unchanged and retain their same 
characteristics in the Converted Bank immediately following the Conversion.

     Following the Conversion, voting rights in the Converted Bank will rest 
exclusively with the sole holder of stock in the Converted Bank, which will be 
the Company. Voting rights in the Company will rest exclusively in the holders 
of the Common Stock.

     The Plan must be approved by the OTS and by an affirmative vote of at least
a majority of the total votes eligible to be cast at a meeting of the
Association's members called to vote on the Plan. Immediately prior to the
Conversion, the Association will have a positive net worth determined in
accordance with generally accepted accounting principles.

                                    OPINION
                                    -------

     Based on the foregoing and in reliance thereon, and subject to the
conditions stated herein, it is our opinion that the following federal income 
tax consequences will result from the proposed transaction.

     1.   The Conversion will constitute a reorganization within the meaning of
          Section 368(a)(1)(F) of the Internal Revenue Code of 1986, as amended
          (the "Code"), and no gain or loss will be recognized to either the
          Association or the Converted Bank as a result of the Conversion (see
                                                                           ---
          Rev. Rul. 80-105, 1980-1 C.B. 78).

     2.   The assets of the Association will have the same basis in the hands of
          the Converted Bank as in the hands of the Association immediately
          prior to the Conversion (Section 362(b) of the Code).

     3.   The holding period of the assets of the Association to be received by
          the Converted Bank will include the period during which the assets
          were held by the Association prior to the Conversion (Section 1223(2)
          of the Code).

     4.   No gain or loss will be recognized by the Converted Bank upon its
          receipt of money from the Company in exchange for shares of common
          stock of the Converted Bank (Section 1032(a) of the Code). The Company
          will be transferring solely cash to the Converted Bank in exchange for
          all the outstanding capital stock of the Converted Bank and therefore
          will not recognize any gain or loss upon such transfer. (Section
          351(a) of the Code; see Rev. Rul. 69-357, 1969-1 C.B. 101).
                              --- 

     5.   No gain or loss will be recognized by the Company upon its receipt of
          money in exchange for shares of the Common Stock (Section 1032(a) of
          the Code).

     6.   No gain or loss will be recognized by the Eligible Account Holders,
          Supplemental Eligible Account Holders, or Other Members of the
          Association upon the issuance to them of deposit accounts in the
          Converted Bank in the same dollar amount and on the same terms and
          conditions in exchange for their deposit accounts in the

 
Board of Directors

          Association held immediately prior to the Conversion. (Section 1001(a)
          of the Code; Treas. Reg. (S)1.1001-1(a)).

     7.   The tax basis of the savings accounts of the Eligible Account Holders,
          Supplemental Eligible Account Holders, and Other Members in the
          Converted Bank received as part of the Conversion will equal the tax
          basis of such account holders' corresponding deposit accounts in the
          Association surrendered in exchange therefor (Section 1012 of the
          Code).

     8.   Each depositor of the Association will recognize gain upon the receipt
          of his or her respective interest in the Liquidation Account
          established by the Converted Bank pursuant to the Plan and the receipt
          of his or her subscription rights deemed to have been received for
          federal income tax purposes, but only to the extent of the excess of
          the combined fair market value of a depositor's interest in such
          Liquidation Account and subscription rights over the depositor's basis
          in the former interests in the Association other than deposit
          accounts. Person who subscribe in the Conversion but who are not
          depositors of the Association will recognize gain upon the receipt of
          subscription rights deemed to have been received for federal income
          tax purposes, but only to the extent of the excess of the fair market
          value of such subscription rights over such person's former interests
          in the Association, if any. Any such gain realized in the Conversion
          would be subject to immediate recognition.

     9.   The basis of each account holder's interest in the Liquidation Account
          received in the Conversion and to be established by the Converted Bank
          pursuant to the Conversion will be equal to the value, if any, of that
          interest.

     10.  No gain or loss will be recognized upon the exercise of a subscription
          right in the Conversion. (Rev, Rul. 56-572, 1956-2 C.B.182).

     11.  The basis of the shares of Common Stock acquired in the Conversion
          will be equal to the purchase price of such shares, increased, in the
          case of such shares acquired pursuant to the exercise of subscription
          rights, by the fair market value, if any, of the subscription rights
          exercised (Section 1012 of the Code).

     12.  The holding period of the Common Stock acquired in the Conversion
          pursuant to the exercise of subscription rights will commence on the
          date on which the subscription rights are exercised (Section 1223(6)
          of the Code. The holding period of the Common Stock acquired in the
          Community Offering will commence on the date following the date on
          which such stock is purchased (Rev. Rul. 70-598, 1970-2 C.B. 168; Rev.
          Rul. 66-97, 1966-1 C.B. 190)

                               SCOPE OF OPINION
                               ----------------

     Our opinion is limited to the federal income tax matters described above
and does not address any other federal income tax considerations or any state,
local, foreign or other federal tax considerations. If any of the information
upon which we have relied is incorrect, or if changes in the relevant facts
occur after the date hereof, our opinion could be affected thereby. Moreover,
our opinion is based on the case law, Code, Treasury Regulations thereunder and
Internal Revenue Service rulings as they now exist. These authorities are all
subject to change, and such change may be made with retroactive effect. We can
give no assurance that, after such change, our opinion would not be different.
We undertake no responsibility to update or supplement our opinion subsequent to
consummation of the Conversion. Prior to that time, we undertake to update or
supplement our opinion in the event of a material change in the federal income
tax consequences set forth above and to file such revised opinion as an exhibit
to the Registration Statement and the Association's Application for Conversion
on Form AC ("Form AC"). This opinion is not binding on the Internal Revenue
Service and there can be no assurance, and none is hereby given, that the
Internal Revenue Service will not take a position contrary to one or more of
the positions reflected in the foregoing opinion, or that our opinion will be
upheld by the courts if challenged by the Internal Revenue Service.
