               OPINION OF WALLACE, BAUMAN, FODIMAN & SHANNON, P.A.


                                  July 31, 1997


Renex Corp.
2100 Ponce de Leon Boulevard, Suite 950
Coral Gables, Florida 33134

         RE:  RENEX CORP. REGISTRATION STATEMENT ON FORM S-1

Gentlemen:

         We have acted as counsel for Renex Corp., a Florida corporation (the
"Company"), in connection with the Company's Registration Statement on Form S-1
(the "Registration Statement") being filed by the Company under the Securities
Act of 1933, as amended, with respect to 3,450,000 shares (the "Shares") of the
Company's common stock, par value $.001 per share (the "Common Stock"). All such
Shares are being sold directly by the Company in accordance with the terms of
the Registration Statement.

         In connection with the preparation of the Registration Statement and
this letter, we have examined, considered and relied upon the following
documents (collectively, the "Documents"): the Registration Statement; the
Company's Articles of Incorporation, as amended and filed with the Secretary of
State of the State of Florida; Bylaws and corporate minute book; and such
matters of law as we have considered necessary or appropriate for the expression
of the opinions contained herein.

         In rendering the opinions set forth below, we have assumed, without
investigation, the genuineness of all signatures and the authenticity of all
documents submitted to us as originals, the conformity to authentic original
documents of all documents submitted to us as copies, and the veracity of the
Documents. As to questions of fact material to the opinions hereinafter
expressed, we have relied upon the representations and warranties of the Company
made in the Documents.

         Based solely upon and subject to the Documents, and subject to the
qualifications set forth below, we are of the opinion that the Shares have been
duly authorized and when the Shares have been duly delivered against payment
therefor, the Shares will be validly issued, fully paid and nonassessable.

         Although we have acted as counsel to the Company in connection with
certain other matters, our engagement is limited to certain matters about which
we have been consulted. Consequently, there may exist matters of a legal nature
involving the Company in connection with which we have not been consulted and
have not represented the Company. This opinion letter is limited to the matters
stated herein and no opinions may be implied or inferred beyond the matters
expressly stated herein. The opinions expressed herein are as of the date
hereof, and we assume no obligation to update or supplement such opinions to
reflect any facts or circumstances that may hereafter come to our attention or
any changes in law that may hereafter occur.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us under the caption "Legal
Matters" in the prospectus contained in the Registration Statement.

                                              Very truly yours,

                                              WALLACE, BAUMAN, FODIMAN
                                              & SHANNON, P.A.
