                  (iii) Reasonable costs and expenses, including reasonable

under this section if the person attains a final judgment in favor of such
person in such enforcement action.

judgment on the merits in favor of such officer or director.

such director or officer or final judgment in favor of such director or officer
other than on the merits except in relation to matters as to which he shall be
adjudged to be liable for negligence or misconduct in the performance of his
duty, only if a majority of the directors of the Registrant determines that such
a director or officer was acting in good faith within what he was reasonably
entitled to believe under the circumstances was the scope of his employment and
authority and for a purpose which he was reasonably entitled to believe under
the circumstances was in the best interest of the Registrant or its
stockholders.

         (c) As used in Section (a) and (b):

                  (i) "Action" means any action, suit or other judicial or

         4.1      Trenton Savings Bank FSB and Peoples Bancorp, M.H.C. 1996
                  Stock Option Plan (Incorporated by reference to Exhibit 10.3
                  of the Registrant's Registration Statement on Form S-4
                  (Registration No. 333-23029) originally filed with the SEC on
                  March 10, 1997, as amended on April 17, 1997.

         5        Opinion of Luse Lehman Gorman Pomerenk & Schick, A
                  Professional Corporation as to the legality of the Common
                  Stock registered hereby.

         23.1     Consent of Luse Lehman Gorman Pomerenk & Schick, A
                  Professional Corporation (contained in the opinion included as
                  Exhibit 5).

         23.2     Consent of KPMG Peat Marwick LLP.

         99.1     Annual Report on Form 10-K of Trenton Savings Bank for the
                  fiscal year ended December 31, 1996.

         99.2     Quarterly Report on Form 10-Q of Trenton Savings Bank for the
                  fiscal quarter ended March 31, 1997.

Item 9.  Undertakings

         The undersigned Registrant hereby undertakes:

         1. To file, during any period in which offers or sales are being made,
a post-effective amendment to this Registration Statement to include any
material information with respect to the Registration Statement not previously
disclosed in this Registration Statement or any material change to such
information in this Registration Statement;

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

         3. To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the 1996 Stock Option Plan; and

         4. 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 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.

         5. 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.

         (a) Any person against whom any action is brought by reason of the fact
that such person is or was a director or officer of the Registrant shall be
indemnified by the Registrant for:

                  (i) Reasonable costs and expenses, including reasonable
attorney's fees, actually paid or incurred by such person in connection with
proceedings related to the defense or settlement of such action;

                  (ii) Any amount for which such person becomes liable by reason
of any judgment in such action;

(iii) Reasonable costs and expenses, including reasonable
attorney's fees, actually paid or incurred in any action to enforce his rights
under this section if the person attains a final judgment in favor of such
person in such enforcement action.

         (b) Indemnification provided for in subparagraph (a) shall be made to
such officer or director only if the requirements of this subparagraph are met:

                  (i) The Registrant shall make the indemnification provided by
subparagraph (a) in connection with any such action which results in a final
judgment on the merits in favor of such officer or director.

                  (ii) The Registrant shall make the indemnification provided by
subparagraph (a) in case of settlement of such action, final judgment against
such director or officer or final judgment in favor of such director or officer
other than on the merits except in relation to matters as to which he shall be
adjudged to be liable for negligence or misconduct in the performance of his
duty, only if a majority of the directors of the Registrant determines that such
a director or officer was acting in good faith within what he was reasonably
entitled to believe under the circumstances was the scope of his employment and
authority and for a purpose which he was reasonably entitled to believe under
the circumstances was in the best interest of the Registrant or its
stockholders.

         (c) As used in Section (a) and (b):

                  (i) "Action" means any action, suit or other judicial or
administrative proceeding, or threatened proceedings, whether civil, criminal,
or otherwise, including any appeal or other proceeding for review;

                  (ii) "Court" includes, without limitation, any court to which
or in which appeal or any proceeding for review is brought;

                  (iii) "Final Judgment" means a judgment, decree, or order
which is appealable and as to which the period for appeal has expired and no
appeal has been taken;

         4.1      Trenton Savings Bank FSB and Peoples Bancorp, M.H.C. 1996

                  of the Registrant's Registration Statement on Form S-4
                  (Registration No. 333-23029) originally filed with the SEC on

         5        Opinion of Luse Lehman Gorman Pomerenk & Schick, A
                  Professional Corporation as to the legality of the Common
                  Stock registered hereby.

         23.1     Consent of Luse Lehman Gorman Pomerenk & Schick, A
                  Professional Corporation (contained in the opinion included as
                  Exhibit 5).

         23.2     Consent of KPMG Peat Marwick LLP.

         99.1     Annual Report on Form 10-K of Trenton Savings Bank for the
                  fiscal year ended December 31, 1996.

         99.2     Quarterly Report on Form 10-Q of Trenton Savings Bank for the
                  fiscal quarter ended March 31, 1997.

Item 9.  Undertakings

         The undersigned Registrant hereby undertakes:

         1. To file, during any period in which offers or sales are being made,
a post-effective amendment to this Registration Statement to include any
material information with respect to the Registration Statement not previously
disclosed in this Registration Statement or any material change to such
information in this Registration Statement;

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

         3. To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the 1996 Stock Option Plan; and

         4. 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 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.

         5. 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.

                                        5
