Ladies and Gentlemen:

     You have  requested  the  opinion  of this firm as to  certain  matters  in
connection with the issuance of Monadnock  Bancorp,  Inc. (the "Company") common
stock, par value $.01 per share (the "Common Stock"),  pursuant to the Monadnock
Bancorp,  Inc. 2007 Equity  Incentive Plan (the "Stock Benefit  Plan").  We have
reviewed the Company's Articles of Incorporation, Registration Statement on Form
S-8 (the "Form S-8"), as well as applicable  statutes and regulations  governing
the Company and the offer and sale of the Common Stock.

     Based on the foregoing, we are of the following opinion:

     Upon the  effectiveness  of the Form S-8, the Common Stock,  when issued in
connection  with the exercise of options  granted  pursuant to the Stock Benefit
Plan and shares of Common Stock granted  under the Stock  Benefit Plan,  will be
legally issued, fully paid and non-assessable.

     This  opinion  has  been  prepared  solely  for the use of the  Company  in
connection  with the  preparation  and filing of the Form S-8, and should not be
used for any other purpose or relied upon by any other person  without the prior
written  consent of this firm.  We hereby  consent to the use of this opinion in
the Form S-8.

                                            Very truly yours,

                                            /s/ LUSE GORMAN POMERENK & SCHICK
