      Re:   Registration Statement on Form SB-2

Ladies and Gentlemen:

      We have acted as counsel to Bio-Bridge Science, Inc., a Delaware
corporation (the "Company"), in connection with the registration with the
Securities and Exchange Commission (the "Commission") on Form SB-2 of 3,657,606
shares of the Company's common stock, par value $0.001 (the "Shares"). In
connection with this registration, we have reviewed the proceedings of the Board
of Directors of the Company relating to the registration and the issuance of the
Shares, the Company's Certificate of Incorporation and all amendments thereto,
the Bylaws of the Company and all amendments thereto, and such other documents
and matters as we have deemed necessary to render the following opinion.

      Based upon that review, it is our opinion that the Shares are, as of the
date hereof, validly issued, fully paid and nonassessable under Delaware law,
including the statutory provisions, all applicable provisions of the Delaware
Constitution and all reported judicial decisions interpreting those laws.

      We hereby consent to the use of this opinion in the registration statement
filed with the Commission in connection with the registration of the Shares and
to reference to our firm under the heading "Legal Matters" in the registration
statement and the prospectus included therein. In giving such consent, we do not
consider that we are "experts" within the meaning of such term as used in the
Securities Act of 1933, as amended, or the rules and regulations of the
Commission issued thereunder, with respect to any part of the registration
statement, including this opinion as an exhibit or otherwise.
