INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Article XVII of the Company's Articles of Incorporation sets forth
circumstances under which directors, officers, employees and agents of the
Company may be indemnified against liability which they may incur in their
capacities, as follows:

                                       3
<PAGE>
 
                                  ARTICLE XVII

                                INDEMNIFICATION

     A.   The Corporation shall indemnify, to the fullest extent permissible
under the Maryland General Corporation Law, any individual who is or was a
director, officer, employee or agent of the Corporation, and any individual who
serves or served at the Corporation's request as a director, officer, partner,
trustee, employee or agent of another corporation, partnership, joint venture,
trust, other enterprise or employee benefit plan, in any proceeding in which the
individual is made a party as a result of his service in such capacity.

     B.   (1)  Reasonable expenses incurred by any person identified in
paragraph A of this Article XVII who is a party to a proceeding will be paid or
reimbursed by the Corporation in advance of the final disposition of the
proceeding upon receipt by the Corporation of:  (i) a written affirmation by
such person of his good faith belief that the standard of conduct necessary for
indemnification by the Corporation as authorized in this Article XVII has been
met; and (ii) a written undertaking by or on behalf of such person to repay the
amount if it shall ultimately be determined that the standard of conduct has not
been met.

          (2) The undertaking required by subparagraph (ii) of paragraph (1) of
this subsection shall be an unlimited general obligation of such person but need
not be secured and may be accepted without reference to financial ability to
make the repayment.

     C.   Nonexclusive.  The indemnification and advance payment of expenses
          ------------                                                      
provided by paragraphs A and B shall not be exclusive of any other rights to
which a person may be entitled by law, bylaw, agreement, vote of stockholders or
disinterested directors, or otherwise.

     D.   Continuation.  The indemnification and advancement of expenses
          ------------                                                  
provided by this Article XVII shall be deemed to be a contract between the
Corporation and the persons entitled to indemnification thereunder, and any
repeal or modification of this Article XVII shall not affect any rights or
obligations then existing with respect to any state of facts then or theretofore
existing or any action, suit or proceeding theretofore or thereafter brought
based in whole or in part upon any such state of facts.  The indemnification and
advance payment provided by paragraphs A and B shall continue as to a person who
has ceased to hold a position named in paragraph A and shall inure to his heirs,
executors and administrators.

     E.   Insurance.  The Corporation shall purchase and maintain insurance on
          ---------                                                           
behalf of any person who holds or who has held any position named in paragraph
A, against any liability incurred by him in any such position, or arising out of
his status as such, whether or not the Corporation would have power to indemnify
him against such liability under paragraphs A and B.

     F.   Intention and Savings Clause.  It is the intention of this Article
          ----------------------------                                      
XVII to provide for indemnification to the fullest extent permitted by the
General Corporation Law of the State of Maryland, and this Article XVII shall be
interpreted accordingly.  If this Article XVII or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify each director, officer, employee, and
agent of the Corporation as to costs, charges, and expenses (including
attorneys' fees), judgments, fines, and amounts paid in settlement with respect
to any action, suit, or proceeding, whether civil, criminal, administrative, or
investigative, including an action by or in the right of the Corporation, to the
full extent permitted by any applicable portion of this Article XVII that shall
not have been invalidated and to the full extent permitted by applicable law.
If the General Corporation Law of the State of Maryland is amended, or other
Maryland law is enacted, to permit further or additional indemnification of the
persons defined in this Article XVII.A, then the indemnification of such persons
shall be to the fullest extent permitted by the General Corporation Law of the
State of Maryland, as so amended, or such other Maryland law.

                                       4
<PAGE>
 
     Any repeal or modification of the foregoing paragraph by the stockholders
of the Corporation shall not adversely affect any right or protection of a
director of the Corporation existing at the time of such repeal or modification.

     In addition, Article XVI of the Company's Articles of Incorporation sets
forth the limits of a director's liability to the Company or its stockholders as
follows:

                                  ARTICLE XVI

                LIMITATION OF OFFICERS' AND DIRECTORS' LIABILITY

     An officer or director of the Corporation, as such, shall not be liable to
the Corporation or its stockholders for money damages, except (i) to the extent
that it is proved that the person actually received an improper benefit or
profit in money, property or services for the amount of the benefit or profit in
money, property or services actually received; (ii) to the extent that a
judgment or other final adjudication adverse to the person is entered in a
proceeding based on a finding in the proceeding that the person's action, or
failure to act, was the result of active and deliberate dishonesty and was
material to the cause of action adjudicated in the proceeding; or (iii) to the
extent otherwise required by Maryland law.  If Maryland law is amended or
enacted after the date of filing of these Articles to further eliminate or limit
the personal liability of officers and directors, then the liability of officers
and directors of the Corporation shall be eliminated or limited to the fullest
extent permitted by Maryland law, as so amended.  Any repeal or modification of
the foregoing paragraph by the stockholders of the Corporation shall not
adversely affect any right or protection of a director of the Corporation
existing at the time of such repeal or modification.

     Pursuant to its Charter and Maryland law, the Company is permitted to
purchase and maintain insurance on behalf of an individual who is or was a
director, officer, employee, or agent of the Company.  Northfield Federal
currently maintains such a policy and it is intended that the Company will
become a party to such policy.

ITEM 9.  UNDERTAKINGS
- ------               

1.   The undersigned registrant hereby undertakes:

     (a)  To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement --

          (i)  To include any prospectus required by Section 10(a)(3) of the
          Securities Act of 1933;

            (ii)  To reflect in the prospectus any facts or events arising after
          the effective date of the registration statement (or the most recent
          post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in the registration statement.  Notwithstanding the foregoing, any
          increase or decrease in volume of securities offered (if the total
          dollar value of securities offered would not exceed that which was
          registered) and any deviation from the low or high and of the
          estimated maximum offering range may be reflected in the form of
          prospectus filed with the Commission pursuant to Rule 424(b) if, in
          the aggregate, the changes in volume and price represent no more than
          20 percent change in the maximum aggregate offering price set forth in
          the "Calculation of Registration Fee" table in the effective
          registration statement;

            (iii)  To include any material information with respect to the plan
          of distribution not previously disclosed in the registration statement
          or any material change to such information in the registration
          statement;

provided, however, that paragraphs (a)(i) and (a)(ii) do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed with or furnished to the Commission by the
registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of
1934 that are incorporated by reference in the registration statement.

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

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

     (d)  If the registrant is a foreign private issuer, to file a post-
effective amendment to the registration statement to include any financial
statements required by Rule 3-19 of this chapter at the start of any delayed
offering or throughout a continuous offering.  Financial statements and
information otherwise required by Section 10(a)(3) of the Act need not be
furnished, provided, that the registrant includes in the prospectus, by means of
a post-effective amendment, financial statements required pursuant to this
paragraph  and other information necessary to ensure that all other information
in the prospectus is at least as current as the date of those financial
statements.  Notwithstanding the foregoing, with respect to registration
statements on Form F-3, a post-effective amendment need not be filed to include
financial statements and information required by Section 10(a)(3) of the Act or
Rule 3-19 of this chapter if such financial statements and information are
contained in periodic reports filed with or furnished to the Commission by the
registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange
Act of 1934 that are incorporated by reference in the Form F-3.

                                       6
<PAGE>
 
  2. The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

  3. The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.

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

INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Article XVII of the Company's Articles of Incorporation sets forth
circumstances under which directors, officers, employees and agents of the
Company may be indemnified against liability which they may incur in their
capacities, as follows:

                                       3
ARTICLE XVII

                                INDEMNIFICATION

     A.   The Corporation shall indemnify, to the fullest extent permissible
under the Maryland General Corporation Law, any individual who is or was a
director, officer, employee or agent of the Corporation, and any individual who
serves or served at the Corporation's request as a director, officer, partner,
trustee, employee or agent of another corporation, partnership, joint venture,
trust, other enterprise or employee benefit plan, in any proceeding in which the
individual is made a party as a result of his service in such capacity.

     B.   (1)  Reasonable expenses incurred by any person identified in
paragraph A of this Article XVII who is a party to a proceeding will be paid or
reimbursed by the Corporation in advance of the final disposition of the
proceeding upon receipt by the Corporation of:  (i) a written affirmation by
such person of his good faith belief that the standard of conduct necessary for
indemnification by the Corporation as authorized in this Article XVII has been
met; and (ii) a written undertaking by or on behalf of such person to repay the
amount if it shall ultimately be determined that the standard of conduct has not
been met.

          (2) The undertaking required by subparagraph (ii) of paragraph (1) of
this subsection shall be an unlimited general obligation of such person but need
not be secured and may be accepted without reference to financial ability to
make the repayment.

     C.   Nonexclusive.  The indemnification and advance payment of expenses
          ------------                                                      
provided by paragraphs A and B shall not be exclusive of any other rights to
which a person may be entitled by law, bylaw, agreement, vote of stockholders or
disinterested directors, or otherwise.

     D.   Continuation.  The indemnification and advancement of expenses
          ------------                                                  
provided by this Article XVII shall be deemed to be a contract between the
Corporation and the persons entitled to indemnification thereunder, and any
repeal or modification of this Article XVII shall not affect any rights or
obligations then existing with respect to any state of facts then or theretofore
existing or any action, suit or proceeding theretofore or thereafter brought
based in whole or in part upon any such state of facts.  The indemnification and
advance payment provided by paragraphs A and B shall continue as to a person who
has ceased to hold a position named in paragraph A and shall inure to his heirs,
executors and administrators.

     E.   Insurance.  The Corporation shall purchase and maintain insurance on
          ---------                                                           
behalf of any person who holds or who has held any position named in paragraph
A, against any liability incurred by him in any such position, or arising out of
his status as such, whether or not the Corporation would have power to indemnify
him against such liability under paragraphs A and B.

     F.   Intention and Savings Clause.  It is the intention of this Article
          ----------------------------                                      
XVII to provide for indemnification to the fullest extent permitted by the
General Corporation Law of the State of Maryland, and this Article XVII shall be
interpreted accordingly.  If this Article XVII or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify each director, officer, employee, and
agent of the Corporation as to costs, charges, and expenses (including
attorneys' fees), judgments, fines, and amounts paid in settlement with respect
to any action, suit, or proceeding, whether civil, criminal, administrative, or
investigative, including an action by or in the right of the Corporation, to the
full extent permitted by any applicable portion of this Article XVII that shall
not have been invalidated and to the full extent permitted by applicable law.
If the General Corporation Law of the State of Maryland is amended, or other
Maryland law is enacted, to permit further or additional indemnification of the
persons defined in this Article XVII.A, then the indemnification of such persons
shall be to the fullest extent permitted by the General Corporation Law of the
State of Maryland, as so amended, or such other Maryland law.

                                       4
Any repeal or modification of the foregoing paragraph by the stockholders
of the Corporation shall not adversely affect any right or protection of a
director of the Corporation existing at the time of such repeal or modification.

     In addition, Article XVI of the Company's Articles of Incorporation sets
forth the limits of a director's liability to the Company or its stockholders as
follows:

                                  ARTICLE XVI

                LIMITATION OF OFFICERS' AND DIRECTORS' LIABILITY

     An officer or director of the Corporation, as such, shall not be liable to
the Corporation or its stockholders for money damages, except (i) to the extent
that it is proved that the person actually received an improper benefit or
profit in money, property or services for the amount of the benefit or profit in
money, property or services actually received; (ii) to the extent that a
judgment or other final adjudication adverse to the person is entered in a
proceeding based on a finding in the proceeding that the person's action, or
failure to act, was the result of active and deliberate dishonesty and was
material to the cause of action adjudicated in the proceeding; or (iii) to the
extent otherwise required by Maryland law.  If Maryland law is amended or
enacted after the date of filing of these Articles to further eliminate or limit
the personal liability of officers and directors, then the liability of officers
and directors of the Corporation shall be eliminated or limited to the fullest
extent permitted by Maryland law, as so amended.  Any repeal or modification of
the foregoing paragraph by the stockholders of the Corporation shall not
adversely affect any right or protection of a director of the Corporation
existing at the time of such repeal or modification.

     Pursuant to its Charter and Maryland law, the Company is permitted to
purchase and maintain insurance on behalf of an individual who is or was a
director, officer, employee, or agent of the Company.  Northfield Federal
currently maintains such a policy and it is intended that the Company will
become a party to such policy.

          dollar value of securities offered would not exceed that which was
          registered) and any deviation from the low or high and of the
          estimated maximum offering range may be reflected in the form of
          prospectus filed with the Commission pursuant to Rule 424(b) if, in
          the aggregate, the changes in volume and price represent no more than
          20 percent change in the maximum aggregate offering price set forth in
          the "Calculation of Registration Fee" table in the effective
          registration statement;

            (iii)  To include any material information with respect to the plan
          of distribution not previously disclosed in the registration statement
          or any material change to such information in the registration
          statement;

provided, however, that paragraphs (a)(i) and (a)(ii) do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed with or furnished to the Commission by the
registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of
1934 that are incorporated by reference in the registration statement.

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

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

     (d)  If the registrant is a foreign private issuer, to file a post-
effective amendment to the registration statement to include any financial
statements required by Rule 3-19 of this chapter at the start of any delayed
offering or throughout a continuous offering.  Financial statements and
information otherwise required by Section 10(a)(3) of the Act need not be
furnished, provided, that the registrant includes in the prospectus, by means of
a post-effective amendment, financial statements required pursuant to this
paragraph  and other information necessary to ensure that all other information
in the prospectus is at least as current as the date of those financial
statements.  Notwithstanding the foregoing, with respect to registration
statements on Form F-3, a post-effective amendment need not be filed to include
financial statements and information required by Section 10(a)(3) of the Act or
Rule 3-19 of this chapter if such financial statements and information are
contained in periodic reports filed with or furnished to the Commission by the
registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange
Act of 1934 that are incorporated by reference in the Form F-3.

                                       6
2. The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

  3. The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.

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