               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT


Item 3. INCORPORATION OF DOCUMENTS BY REFERENCE.

         (a) Cryocon's Annual Report on Form 10-KSB for the fiscal year ended
             March 31, 2001.

         (b) Part I, Item 8 (Description of Securities) contained in Cryocon's
             registration statement on Form 8-A, SEC file No. 0-25810.

     In addition, all documents subsequently filed pursuant to Sections 13(a),
13(c), 14 and 15(d) of the Securities Exchange Act of 1934, prior to the filing
of a post-effective amendment which indicates that all securities offered have
been sold or which deregisters all securities then remaining unsold, shall be
deemed to be incorporated by reference into this registration statement and to
be a part hereof from the date of filing of such documents.


Item 4. DESCRIPTION OF SECURITIES.

     Not applicable.

Item 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

     The validity of the securities that may be offered will be passed upon for
Cryocon by Marcus Sanders, Attorney at Law, 22 Battery Street, Suite 701, San
Francisco, California 94105. Mr. Marcus Sanders is a sole-proprietor of law
practice and provided advice with respect to this matter. Mr. Sanders does not

Item 6. INDEMNIFICATION OF OFFICERS AND DIRECTORS.

     Article SEVENTH of Cryocon's Amended Articles of incorporation authorizes
CRYOCON to indemnify any current or former director, officer, employee, or agent
of CRYOCON, or a person serving in a similar post in another organization at the
request of CRYOCON, against expenses, judgments, fines, and amounts paid in
settlement incurred by him in connection with any threatened, pending, or
completed action, suit, or proceeding, whether civil, criminal, administrative,
or investigative, to the fullest extent not prohibited by the Colorado Business
Corporation Act, public policy or other applicable law. Sections 7-109-103 and
7-109-107 of the Colorado Business Corporation Act authorize a corporation to
indemnify its directors, officers, employees, or agents in terms sufficiently
broad to permit such indemnification under certain circumstances for liabilities

(including provisions permitting advances for expenses incurred) arising under
the 1933 Act.

Item 7. EXEMPTION FROM REGISTRATION CLAIMED.

     Not Applicable.

Item 8.  EXHIBITS.

     The Exhibits to this registration statement are listed in the Index to
Exhibits on page 4.

Item 8. UNDERTAKINGS.

     The undersigned registrant hereby undertakes:

     (1) To file, during any period in which offers and sales are being made, a
post-effective amendment to this registration statement to include any material
information with respect to the plan of distribution not previously disclosed in
the registration statement or any material change to such information in the
registration statement.

     (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     (4) That, for purposes of determining any liability under the Securities
Act of 1933, each filing of the registrant's annual report pursuant to Section
13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by
reference in the registration statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

     (5) Insofar as indemnification for liabilities under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act, and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
