CRYOCON, INC - S-8 - Registration Statement                Date Filed: 9/29/2000
--------------------------------------------------------------------------------

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.
