North Palm Beach, Florida 33408

Gentlemen:

        We have acted as special counsel to Community Savings Bankshares, Inc.,
a Delaware corporation (the "Company"), in connection with the preparation and
filing with the Securities and Exchange Commission pursuant to the Securities
Act of 1933, as amended, of the Registration Statement on Form S-1 (the
"Registration Statement"), relating to the issuance of up to 12,707,500 shares
(which may be increased to up to 14,613,625 shares under certain circumstances
described below) of the Company's common stock, par value $1.00 per share (the
"Common Stock"), in connection with the consummation of the following
transactions: (1) Community Savings Bankshares, Inc. a federally chartered
corporation (the "Mid-Tier Holding Company"), which currently holds 100% of the
common stock of Community Savings, F. A. (the "Association"), will convert to a
federal interim stock savings association and simultaneously merge into the
Association, with the Association being the surviving entity; (2) ComFed, M. H.
C. (the "MHC"), which currently holds 51.34% of the outstanding shares of common
stock of the Mid-Tier Holding Company, will convert from mutual form to a
federal interim stock savings association and simultaneously merge into the
Association, with the Association being the surviving entity; (3) the
Association will then merge with an interim institution to be formed as a wholly
owned subsidiary of the Company, with the Association being the surviving
entity; (4) the outstanding shares of Mid-Tier Holding Company common stock
(other than those held by the MHC, which will be cancelled) will be converted
into shares of the Company's common stock, $1.00 par value per share ("Company
Common Stock") pursuant to a ratio that will result in the holders of such
shares owning in the aggregate approximately the same percentage of the Company
as they currently own of the Mid-Tier


   2


Holding Company (as adjusted for excess waived dividends), before giving effect
to such shareholders purchasing additional shares in a concurrent stock offering
conducted by the Company or receiving cash in lieu of fractional shares; and (5)
the offer and sale of shares of the Company's common stock (such steps
collectively referred to as the "Conversion"). In this regard, we have examined
the Certificate of Incorporation and Bylaws of the Company, resolutions of the
Boards of Directors of the Company, the MHC, the Mid-Tier Holding Company and
the Association, the Plan of Conversion and Agreement and Plan of
Reorganization, as amended (the "Agreement"), and such other documents and
matters of law as we deemed appropriate for the purposes of this opinion.

        Based upon the foregoing, we are of the opinion as of the date hereof
that the Common Stock has been duly and validly authorized, and when issued in
accordance with the terms of the Agreement, and upon the receipt of the
consideration required thereby, will be legally issued, fully paid and
non-assessable.

        We hereby consent to the filing of this opinion as an exhibit to the
Company's Registration Statement and to the references to this firm under the
headings "The Conversion - Tax Aspects" and "Legal Matters" in the Prospectus
contained in the Registration Statement.

                                      Very truly yours,

                                      ELIAS, MATZ, TIERNAN & HERRICK L.L.P.
