PSB Group, Inc.
Attn: Robert L. Cole
1800 East Twelve Mile Road
Madison Heights, MI 48071


Gentlemen:

         We have acted as counsel to PSB Group, Inc. in connection with the
preparation and filing of a registration statement on Form S-3 (the
"Registration Statement"), under the Securities Act of 1933, covering 200,000
shares of PSB Group, Inc. Common Stock ("Common Stock") offered pursuant to the
PSB Group, Inc. Dividend Reinvestment Plan (the "Plan").

         We have examined originals or copies, certified or otherwise identified
to our satisfaction, of such corporate records, certificates, and other
documents and conducted interviews with officers as we considered necessary or
appropriate for purpose of this opinion.

         It is our opinion that the Common Stock issuable under the Plan has
been duly authorized and when issued in the manner described in the Plan, will
be legally issued, fully paid, and non-assessable.

         We consent to the use of our name under the caption "Legal Matters" in
the Prospectus which forms a part of the Registration Statement.


                                         VERY TRULY YOURS,

                                         HOWARD & HOWARD

                                         /s/ TIMOTHY E. KRAEPEL

                                         TIMOTHY E. KRAEPEL
