     Re: Cryocon, Inc.
          Registration Statement on Form S-3

Gentlemen:

         Cryocon, Inc. (the "Company") retained me in connection with the
registration statement (the "Registration Statement") on Form S-3 to be filed by
the Company with the Securities and Exchange Commission relating to the
securities of the Company. You requested that I render my opinion as to whether
or not the securities the Company wants to issue on the terms set forth in the
Registration Statement will be validly issued, fully paid, and nonassessable.

         In connection with this request, I examined the following:

            1.  Articles of Incorporation of the Company, and amendments
                thereto;
            2.  Bylaws of the Company;
            3.  Unanimous consent resolutions of the Company's board of
                directors;
            4.  The Convertible Dentures between Cryocon, Inc. and Paragon
                Venture Fund LL;
            5.  The Registration Statement;
            6.  Warrant Issuance to Bourns, Inc.;
            7.  Warrant Issuance to Todd Moore;
            8.  Notice and issuance of the Warrants to the Shareholders

         I examined such other corporate records and documents and have made
such other examinations, as I have deemed relevant.

         Based on the above examination, I am of the opinion that the securities
of the Company to be issued pursuant to the Registration Statement are validly
authorized and, when issued in accordance with the terms set forth in the
Registration Statement, will be validly issued, fully paid, and nonassessable
under corporate laws of the state of Utah.

         This opinion is limited in scope to the shares to be issued pursuant to
the Registration Statement and does not cover subsequent issuance of shares to
be made in the future. Such transactions are required to be included in either a
new registration statement or a post-effective amendment to the Registration



Statement, including updated opinions concerning the validity of issuance of
such shares.

         Further, I consent to my name, Marcus A. Sanders, Attorney At Law being
included in the Registration Statement as having rendered the foregoing opinion
and as having represented the Company in connection with the Registration
Statement.

Sincerely,

/s/

Marcus A. Sanders, Esq.
