            RE:   NEW YORK BANCORP CAPITAL TRUST
                  ------------------------------

Ladies and Gentlemen:

            We have acted as special Delaware counsel for New York Bancorp Inc.,
a Delaware corporation (the "Company"), and New York Bancorp Capital Trust, a
Delaware business trust (the "Trust"), in connection with the matters set forth
herein. At your request, this opinion is being furnished to you.

            For purposes of giving the opinions hereinafter set forth, our
examination of documents has been limited to the examination of originals or
copies of the following:

            (a) The Certificate of Trust of the Trust, dated as of August 28,
1997 (the "Certificate"), as filed in the office of the Secretary of State of
the State of Delaware (the "Secretary of State") on August 28, 1997;

            (b) The Declaration of Trust of the Trust, dated as of August 28,
1997, by and among the Company and the trustees of the Trust named therein;

            (c) A form of Amended and Restated Declaration of Trust of the Trust
(including Exhibits A-1 and B-1 thereto) (the "Declaration"), to be entered into
among the Company, as sponsor, the trustees of the Trust named therein, the
Administrators and the holders, from time to time, of undivided beneficial
interests in the assets of the Trust, attached as an exhibit to the Registration
Statement (as defined below);

            (d) Amendment No. 1 to the Registration Statement on Form S-3 (the
"Registration Statement"), including a preliminary prospectus (the
"Prospectus"), relating to the 8.00% Convertible Trust Preferred Securities of
the Trust representing undivided beneficial interests in the assets of the Trust
(each, a "Capital Security" and collectively, the "Capital Securities"), as
proposed to be filed by the Company and the Trust with the Securities and
Exchange Commission on or about September 17, 1997; and

            (e) A Certificate of Good Standing for the Trust, dated September
17, 1997, obtained from the Secretary of State.

            Initially capitalized terms used herein and not otherwise defined
are used as defined in the Declaration.

            For purposes of this opinion, we have not reviewed any documents
other than the documents listed in paragraphs (a) through (e) above. In
particular, we have not reviewed any document (other than the documents listed
in paragraphs (a) through (e) above) that is referred to in or incorporated by
reference into the documents reviewed by us. We have assumed that there exists
no provision in any document that we have not reviewed that is inconsistent with
the opinions stated herein. We have conducted no independent factual
investigation of our own but rather have relied solely upon the foregoing
documents, the statements and information set forth therein and the additional
matters recited or assumed herein, all of which we have assumed to be true,
complete and accurate in all material respects.

            With respect to all documents examined by us, we have assumed (i)
the authenticity of all documents submitted to us as authentic originals, (ii)
the conformity with the originals of all documents submitted to us as copies or
forms, and (iii) the genuineness of all signatures.

            For purposes of this opinion, we have assumed (i) that the
Declaration constitutes the entire agreement among the parties thereto with
respect to the subject matter thereof, including with respect to the creation,
operation and termination of the Trust, and that the Declaration and the
Certificate are in full force and effect and have

not been amended, (ii) except to the extent provided in paragraph 1 below, the
due creation or due organization or due formation, as the case may be, and valid
existence in good standing of each party to the documents examined by us under
the laws of the jurisdiction governing its creation, organization or formation,
(iii) the legal capacity of natural persons who are parties to the documents
examined by us, (iv) that each of the parties to the documents examined by us
has the power and authority to execute and deliver, and to perform its
obligations under, such documents, (v) the due authorization, execution and
delivery by all parties thereto of all documents examined by us, (vi) the
receipt by each Person to whom a Capital Security is to be issued by the Trust
(collectively, the "Capital Security Holders") of a Certificate Evidencing
Capital Securities (substantially in the form of Exhibit A-1 to the Declaration)
and the consideration for the Capital Security acquired by it, in accordance
with the Declaration and the Registration Statement, and (vii) that the Capital
Securities are issued to the Capital Security Holders in accordance with the
Declaration and the Registration Statement. We have not participated in the
preparation of the Registration Statement and assume no responsibility for its
contents.

            This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto. Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder which are currently in effect.

            Based upon the foregoing, and upon our examination of such questions
of law and statutes of the State of Delaware as we have considered necessary or
appropriate, and subject to the assumptions, qualifications, limitations and
exceptions set forth herein, we are of the opinion that:

            1. The Trust has been duly created and is validly existing in good
standing as a business trust under the Business Trust Act.

            2. The Capital Securities will represent valid and, subject to the
qualifications set forth in paragraph 3 below, fully paid and nonassessable
undivided beneficial interests in the assets of the Trust.

            3. The Capital Security Holders, as beneficial owners of the Trust,
will be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware. We note that the Capital Security
Holders may be obligated to make payments as set forth in the Declaration.
