      Re:   Registration Statement on Form SB-2

Gentlemen:

      We have acted as counsel for Bio-Bridge Science, Inc., a Delaware
corporation (the "Company"), in connection with the preparation of a
Registration Statement on Form SB-2 filed by the Company with the Securities and
Exchange Commission (the "Commission") pursuant to the Securities Act of 1933,
as amended ("Act"), relating to the sale of up to 3,618,064 shares of common
stock offered for public resale by certain selling security holders, consisting
of (i) up to 2,000,000 shares of common stock reserved for Dutchess Private
Equities Fund, LP, a Delaware limited partnership, under the equity line (the
"Purchase Shares"); and (ii) 1,618,064 shares of our common stock held by other
selling security holders. This opinion is being furnished pursuant to Item
601(b)(5) of Regulation S-B under the Act.

      In connection with rendering the opinion as set forth below, we have
reviewed (a) the Registration Statement and the exhibits thereto; (b) the
Company's Certificate of Incorporation (c) the Company's Bylaws; (d) certain
records of the Company's corporate proceedings as reflected in its minute books,
and (e) such statutes, records and other documents as we have deemed relevant.

      In our examination, we have assumed the genuineness of all signatures, the
authenticity of all documents submitted to us as originals, and conformity with
the originals of all documents submitted to us as copies thereof. In addition,
we have made such other examinations of law and fact as we have deemed relevant
in order to form a basis for the opinion hereinafter expressed.

Based upon the foregoing, we are of the opinion that (i) the shares issued by
the Company which are included in this Registration Statement are validly
issued, fully paid and nonassessable; and (ii) the Purchase Shares have been
duly authorized and, when issued against payment of the requisite purchase
price, will be validly issued, fully paid and nonassessable.




      We hereby consent to the use of this opinion as an exhibit to the
Registration Statement and to the references to this firm in the Registration
Statement. In giving this consent, we do not thereby admit that we are acting
within the category of persons whose consent is required under Section 7 of the
Securities Act and the rules and regulations of the Securities and Exchange
Commission thereunder.
