Asyst Corporation
43 West 33 Street
New York, New York 10001

Gentlemen:

      As special counsel for Amazon Biotech,  Inc., a Utah corporation  formerly
known as Asyst  Corporation  (the  "Company"),  we have examined its Articles of
Incorporation  and  Bylaws,  as  amended,  and  such  other  corporate  records,
documents and proceedings,  and such questions of law as we have deemed relevant
for the  purpose  of this  opinion.  We have  also,  as such  counsel,  examined
Amendment No. 1 to the  registration  statement of the Company on Form S-8 to be
filed by the Company with the  Securities  and Exchange  Commission  on or about
June 28, 2004 (the "Registration Statement") covering the registration under the
Securities  Act of 1933, as amended,  an aggregate of up to 5,500,000  shares of
common stock, $.001 par value (the "Shares") to be issued pursuant to the Amazon
Biotech, Inc. Amended and Restated 2004 Stock Compensation Plan (the "Plan").

      Upon the basis of such examination,  we are of the opinion that the Shares
will be,  when issued and sold in the manner  referred to in the Plan,  duly and
validly issued as fully paid and non-assessable securities of the Company.

      We hereby  consent  to the  filing of this  opinion  as an  exhibit to the
Registration Statement.

                                          Very truly yours,

                                          /s/ Spectrum Law Group, LLP
                                          --------------------------------------
