         Re:   FedFirst Financial Corporation 2006 Equity Incentive Plan
               ---------------------------------------------------------

Board Members:

         We have been requested by FedFirst Financial Corporation, a Federal
corporation (the "Company"), to issue our opinion in connection with the
registration of 453,617 shares of the Company's common stock (the
"Registration"), par value $.01 per share. The Registration covers 453,617
shares that may be issued as awards under the FedFirst Financial Corporation
2006 Equity Incentive Plan (the "Plan"). The Plan provides that no more than
324,012 shares may be issued upon the exercise of stock options and no more than
129,605 shares may be issued upon the grant of restricted stock. The
Registration is being effected on Form S-8 under the Securities Act of 1933, as
amended.

         We have made such legal and factual examinations and inquiries as we
have deemed advisable for the purpose of rendering this opinion. In our
examination, we have assumed and have not verified (i) the genuineness of all
signatures, (ii) the authenticity of all documents submitted to us as originals,
(iii) the conformity with the originals of all documents supplied to us as
copies, and (iv) the accuracy and completeness of all corporate records and
documents and of all certificates and statements of fact, in each case given or
made available to us by the Company or its subsidiary.

         Based on the foregoing and limited in all respects to Federal law, it
is our opinion that the shares reserved for issuance under the Plan are duly
authorized and, with respect to shares of Company common stock issuable upon the
exercise of stock options granted or to be granted under the Plan, upon payment
for and issuance of the common stock upon exercise of such stock options, and,
with respect to the awards of restricted stock under the Plan, upon issuance of
such shares of stock in the manner described in the Plan, such shares will be
validly issued, fully paid and nonassessable.
