        Re:     TSX Corporation
                Registration Statement on Form S-3

Ladies and Gentlemen:

        We have acted as special Nevada counsel to TSX Corporation, a Nevada
corporation (the "Company"), in connection with its Registration Statement on
Form S-3 (the "Registration Statement") to be filed with the Securities and
Exchange Commission under the Securities Act of 1933, as amended, relating to
the registration of a secondary offering and sales by William H. Lambert,
Chairman of the Board, President and Chief Executive Officer of the Company, of
up to 300,000 shares of the Company's common stock, $.01 par value per share
(the "Lambert Shares"), underlying certain options granted to Lambert (the
"Lambert Options").

        We have examined all instruments, documents and records which we deemed
relevant and necessary for the basis of our opinion hereinafter expressed. In
such examination, we have assumed the genuineness of all signatures and the
authenticity of all documents submitted to us as originals and the conformity
to the originals of all documents submitted to us as copies.

        Based on such examination and subject to the limitations hereinabove
provided, we are of the opinion that the Lambert Shares, when issued and sold
in accordance with the terms of the Lambert Options and upon receipt of the
consideration required thereunder, will be legally issued, fully paid and
nonassessable.
