<R/>

    
   
Of  the  4,379,590   shares   of   Common   Stock    of   THERMOGENESIS   CORP.
("THERMOGENESIS"  or  the  "Company") being offered (the "Offering"), 2,901,589
shares are being offered by  certain  stockholders of the Company (the "Selling
Stockholders").  Of the shares being offered  by  Selling Stockholders, 145,587
shares  were  issued pursuant to the Company's manufacturing/license  agreement
with On-Time Manufacturing, Inc. and 2,756,002 shares were issued in connection
with the Company's  private placement completed in November 1996.  In addition,
the Company is registering  the  resale  of  1,478,001 warrants ("Warrants") to
purchase  1,478,001  shares of Common Stock issuable  upon  exercise  of  those
Warrants.  The Warrants  were also issued by the Company in connection with the
private placement, and the  resale  of  the  warrants  may be sold in a primary
offering,  or  the  shares of Common Stock acquired upon the  exercise  of  the
Warrants may be sold  in  a  secondary  offering,  by  the Selling Stockholders
pursuant  to this Prospectus.  See "The Company - Recent  Financing";  "Selling
Stockholders".   At  June  30,  1996, the Company had an accumulated deficit of
$6,382,928.
<R/>

    
   
The shares of Common Stock and Warrants  owned  by the Selling Stockholders may
be offered for sale from time to time at market prices  prevailing at such time
or at negotiated prices by the Selling Stockholders, and  without  payments  of
any  underwriting  discounts  or  commission,  except  for  usual and customary
selling commissions paid to brokers or dealers.  THERMOGENESIS  Common Stock is
traded and listed on the Nasdaq Stock Market, SmallCap Market, under the symbol
"KOOL".   See  "Description  of Securities".  The average of the high  and  low
price for the Company's Common  Stock  on April 17, 1997 was $3.25, as reported
on the Nasdaq SmallCap Market, and the Company  does not, therefore, anticipate
the  exercise of the Warrants.   The Warrants are  not  traded  on  the  Nasdaq
Market,  and  it  is not anticipated that there will ever be any market for the
Warrants.  The Company  will  not  receive  any  proceeds  from the sale of any
Common  Stock  or the resale of any Warrants by the Selling Stockholders.   See
"SELLING STOCKHOLDERS".   Expenses  of  the  Offering, estimated to be $22,000,
will be paid in full by the Company.

                               PROSPECTUS SUMMARY

The following summary is qualified in  its entirety by the detailed information
and financial statements appearing elsewhere  or  incorporated  by reference in
this Prospectus.  This Prospectus contains forward-looking statements  that are
subject  to  risks  and  uncertainties,  including,  but not limited to, delays
beyond  the  Company's  control  with respect to regulatory  approvals,  market
acceptance  of  new technologies, and  other  risks  detailed  in  the  section
entitled  Risk  Factors  and  elsewhere  in  the  Company's  filings  with  the
Securities and Exchange Commission.  A glossary of certain technical terms used
in this Prospectus is located at the back of the Prospectus.

    
   
                                   THE COMPANY
THERMOGENESIS CORP.  (the  "Company")  is  a  bio-medical company that designs,
manufactures   and  distributes  thermodynamic  systems   which   utilize   its
proprietary heat  transfer technology for the storage, retrieval and processing
of  blood products and  biological  tissues  ("Proprietary  Technology").   The
Company,  originally  incorporated  in Delaware on September 26, 1986, as Insta
Cool Inc. of North America, changed its  name to THERMOGENESIS CORP. in January
1995 to better reflect the thermodynamic segment  of the biotechnology industry
which it began servicing.  Historically, the Company's  primary  revenues  have
been  from  sales  of blood plasma freezers to hospitals, blood banks and blood
transfusion centers for rapid freezing of blood plasma.  Currently, the Company
is manufacturing several  categories  of  thermodynamic devices which are being
sold  to the blood plasma industry under permission  from  the  Food  and  Drug
Administration  ("FDA").  Other  potential  applications  and  markets  for the
Company's   Proprietary   Technology   includes   medical   and  pharmaceutical
applications,  and  industrial  applications.   During  the fiscal  years  1988
through 1995, the Company focused its efforts on research  and  development and
on refining product design and application.  The Company has also  continuously
sought  new applications for its technology, including the design of  a  device
used  for   harvesting  of  fibrinogen  rich  cryoprecipitate  for  use  as  an
intravenous  treatment   of  clotting  protein  deficient  patients,  or  as  a
hemostatic agent or tissue  sealant in certain surgical and medical procedures.
See "The Company and Recent Events - Current Products and Development Efforts".
<R/>
To date, the Company's revenues  have  been  principally  derived from sales of
blood plasma freezers and thawers to hospitals and blood banks  throughout  the
world.   With  total  revenues  for  the  fiscal  year  ended  June 30, 1996 of
approximately $4.1 million, the Company has attained a dominant  share  of  the
small,  but  medically  important  market  for  plasma  thawers  and  freezers.
Revenues  increased  for  the three and six months ended December 31, 1996,  by
approximately 219% and 159%,  respectively, from the corresponding 1995 period.
The  sales  increase  was  due primarily  to  a  key  customer  order  totaling
approximately $3,900,000, which order was substantially completed by the end of
December 1996.

    
   <R/>

    
   
                                 USE OF PROCEEDS
The Company will not receive  any  proceeds  from  the  sale of Common Stock or
resale  of  Warrants by the Selling Stockholders.  Assuming  the  Warrants  are
exercised, the  Company  would receive approximately $5,742,034, which would be
used for continued research and development, and for general corporate purposes
and operations.
<R/>
                                  RISK FACTORS
For a discussion of considerations  relevant  to  an  investment  in the Common
Stock and Warrants, see the section entitled "RISK FACTORS" beginning  on  page

                                  THE OFFERING

Common Stock  and  Warrants offered by the Selling Stockholders, and the Common
Stock to be issued upon  the exercise of outstanding Warrants issued as part of
the Units in the private placement.   To  the extent required under the federal
securities laws, this Prospectus may be used  for  resale  of Common Stock upon
the exercise of the Warrants by the holders of such Warrants.

                                  RISK FACTORS

An  investment  in the Common Stock described herein entails a number  of  very
significant risks.   Because  of  these risks, funds should only be invested by
persons  able  to bear the risk of and  withstand  the  loss  of  their  entire
investment.  Prospective  investors  should  also consider the following before
making an investment decision.

    
   
LACK OF PROFITABILITY.  Except for net income  of  $11,246  for  the year ended
June  30, 1994 on net sales of $2,678,192, the Company has not been  profitable
since inception.   For the year ended June 30, 1996, the Company had a net loss
of $568,534 on net sales  of  $4,124,634 and an accumulated deficit at June 30,
1996,  of  $6,382,928.   See  "Annual   Report  on  Form  10-KSB  --  Financial
Statements".  For the six months ended December 31, 1996, the Company had a net
loss of $564,719 on sales of $4,348,286.
<R/>

    
   
DEPENDENCE  UPON NEW PRODUCTS FOR FUTURE GROWTH.   Historically,  substantially
all of the Company's  revenue has been from the sales of product related to the
freezing, thawing and storing of blood plasma.  Because the Company expects the
blood plasma market to  have  limited growth, the future success of the Company
will  be  dependent  upon  new  applications   of   its  technology,  including
application of products in the biotechnology market.   The  Company  intends to
concentrate on developing novel thermodynamic blood processing systems such as:
(1)   a   cryoprecipitate   processing   device   with   disposable  containers
("CryoSeal<trademark> System"); (2) a long-term blood sample storage, inventory
management  and  retrieval  system  ("JRC");  and  (3)  system for  collecting,
processing, controlled-rate freezing and inventory management  of  thermolabile
products  ("N{2}  BioArchive<trademark> System").  See "The Company and  Recent
Events - Current Products  and  Development  Efforts."   Although  these  three
potential  products use technology related to the freezing, thawing and storage
of blood plasma,  development of these products represents a departure from the
Company's  current core  business.   Further,  although  the  Company  has  had
encouraging  discussions  with  experts  in  areas  of  application  for  these
potential  products,  development  of  each product is still in its development
phase  and  the  Company has no contracts for  sales  of  two  of  these  three
products.  No assurance  can  be given that all of these potential products can
be successfully developed, and  if  developed,  that  a market will develop for
them.
<R/>

    
   
POSSIBLE NEED FOR ADDITIONAL FINANCING.  Based on current  sales  and projected
development  costs for products currently in development, the Company  believes
that it will have  sufficient  working  capital for its operations for the 1997
fiscal year.  In the event actual sales of  the  Company's products do not meet
the Company's expectations in any given period, or  development  and production
costs  increase  significantly,  the  Company  may  need  to  secure additional
financing to complete and fully implement its business objectives.  The Company
has  been  establishing  a working relationship with its bank, and  is  working
towards securing a line of  credit  secured  by its accounts receivable.  There
can be no assurance that the Company will be able  to  obtain a working line of
credit or that it will be able to obtain one on terms that  would be beneficial
to the Company.  In the event that the Company's working capital forecast falls
short of its needs, additional equity financing would be required.  The Company
currently has no plans to seek any additional equity financing and no assurance
can  be  given  that  such  financing  would  be  available if needed,  and  if
available,  that  it  will  be  obtained  on terms favorable  to  the  Company.
Furthermore, delays in receipt of any required  governmental approvals prior to
marketing products in development, or requirements for additional testing prior
to approval, may result in decreased revenues and  increased  development costs
that might require the Company to seek additional financing sooner.   See "Risk
Factors -- Government Regulation Associated with Products".
<R/>

LACK OF TESTING DATA.  The Company has only initiated laboratory testing of its
CryoSeal<trademark>  System  and its N{2} BioArchive<trademark> System.   There
can be no assurance that the testing  can  be successfully completed within the
Company's expected time frame and budget, or  that  the Company's products will
prove effective in the required clinical trials.  If  the  Company is unable to
conclude successfully the clinical trials of its products in  development,  the
Company's  business,  financial  condition  and  results  of operation could be
adversely affected.

GOVERNMENT REGULATION ASSOCIATED WITH PRODUCTS.  The majority  of the Company's
products  require  clearance  to  market  in the United States from the  United
States Food and Drug Administration ("FDA"),  which  may  limit or circumscribe
applications  for U.S. markets for which the Company's products  may  be  sold.
Further, if the  Company  cannot  establish  that  its product is substantially
equivalent,  or  superior,  in  safety  and efficacy to a  previously  approved
product, delays may result in final clearance  from  the  FDA for marketing its
products.  No assurance can be given that FDA clearance to market in the United
States  will be obtained.   The Company's products are also  required  to  meet
certain  other  criteria  or  receive  certain  approvals  from  other  foreign
governments  for  marketing  and  sales.   See "The Company and Recent Events -
Government Regulation".

    
   
NO ASSURANCE OF NEW PRODUCT ACCEPTANCE.  The market acceptance of the Company's
new products in development will depend upon  the  medical community and third-
party payers accepting the products as clinically useful, reliable accurate and
cost effective compared to existing and future products  or procedures.  Market
acceptance  will  also  depend  on  the  Company's ability to adequately  train
technicians  on  how  to  use  the  CryoSeal<trademark>  System  and  the  N{2}
BioArchive<trademark> System.  Even if  the  Company's  systems  are clinically
adopted, the use may not be recommended by the medical profession  or hospitals
unless  acceptable  reimbursement  from  health care and third-party payers  is
available.   Failure  of either of these new  systems  to  achieve  significant
market share could have  material  adverse  effects  on the Company's long term
business, financial condition and results of operation.   See "Annual Report on
Form   10-KSB   --   Description  of  Business";  "Risk  Factors  --  Uncertain
Availability of Third-Party Reimbursement".
<R/>
UNCERTAIN AVAILABILITY  OF  THIRD-PARTY  REIMBURSEMENT.   In the United States,
hospitals,  physicians  and other health care providers that  purchase  medical
devices rely on third-party  payers,  principally  Medicare,  Medicaid, private
health  insurance  plans  and  other  sources  of  reimbursement  for costs  of
procedures  in  which  medical devices are used.  With health care increasingly
relying on managed care  systems through which to deliver their surgeries for a
fixed cost per person, which  may  be independent and different from the actual
costs  for such care, substantial scrutiny  may  prevent  the  use  of  certain
procedures  or medical devices based on the lack of reimbursement.  Because the
Company's CryoSeal<trademark>  System and N{2} BioArchive<trademark> System are
currently  in  final  phases of development  and  have  not  yet  received  FDA
clearance or approval,  there  exists uncertainty regarding the availability of
third-party reimbursement.  Failure  to  secure third-party reimbursement could
adversely affect the Company's revenues and  market  for  the  new  products in
development.  See "The Company and Recent Events -- Third-Party Reimbursement".

    
   
FOREIGN  REGULATORY  APPROVALS.   The Company's products often require  foreign
regulatory registrations  or  approvals  prior  to  marketing  the  products in
certain foreign countries.
<R/>

    
   
REIMBURSEMENT   FOR  MEDICAL  DEVICES  AND  PROCEDURES.   International  market
acceptance  of  the  Company's  new  products  in  development  would  also  be
dependent, in part,  upon  the  availability of reimbursement within prevailing
health care payment systems in each  country.   Reimbursement  and  health care
payment  systems  in  international markets vary significantly by country,  and
include both government  sponsored  health care (e.g. Japan) as well as private
insurance.  There can be no assurance  that  reimbursement  approvals  will  be
obtained  in  any  given  foreign  market in a timely manner which could have a
material adverse effect on market acceptance  of  the Company's new products in
international markets.
<R/>
RISK OF SOFTWARE DEFECTS.  The Company's CryoSeal<trademark>  System  and  N{2}
BioArchive<trademark>  System  currently  in final development rely on computer
software   components   that   direct   the   harvesting    process    of   the
CryoSeal<trademark>  System,  and  the  controlled-rate  freezing,  storage and
retrieval  robotics of the N{2} BioArchive<trademark> System.  The software  in
these devices, including updated versions in the future, may contain undetected
errors or failures.   There  can  be  no assurance that, despite testing by the
Company  and  customers,  errors will not  be  found  in  the  software  during
continuous use, resulting in  loss  or  delay in market acceptance, which could
have  a  material  effect on the Company's business,  financial  condition  and
results of operations.

RELIANCE ON PATENTS  AND  OTHER  PROPRIETARY INFORMATION.  The Company believes
that patent protection is important  for products and potential segments of its
current and proposed business.  The Company  currently  holds four (4) patents,
and has five (5) patents pending to protect the designs of  an additional three
(3) products which the Company intends to market.  See "Annual  Report  on Form
10-KSB".   There  can be no assurance, however, as to the breadth or degree  of
protection afforded  to the Company or the competitive advantage derived by the
Company from current patents  and future patents, if any.  Although the Company
believes that its patents and the  Company's  existing and proposed products do
not infringe upon patents of other parties, it  is  possible that the Company's
existing patent rights may be challenged and found invalid  or found to violate
proprietary rights of others.  In the event any of the Company's  products  are
challenged as infringing, the Company would be required to modify the design of
its  product,  obtain  a  license or litigate the issue.  There is no assurance
that the Company would be able  to finance costly patent litigation, or that it
would be able to obtain licenses  or  modify  its  products in a timely manner.
Failure  to  defend  a patent infringement action or to  obtain  a  license  or
implementation of modifications  would  have  a  material adverse effect on the
Company's  continued  operations.   See  "Annual  Report   on  Form  10-KSB  --
Description of Business".
<R/>
TRADE  SECRETS.   The  Company  also  relies  in  part  on  trade  secrets  and
proprietary know-how, and it employs various methods to protect its technology,
such  as  use  of  confidentiality  agreements  with  employees,  vendors,  and
customers.   However, such methods may not afford complete protection and there
can be no assurance  that  others  will  not  obtain the Company's know-how, or
independently develop it.

DEPENDENCE  ON  KEY PERSONNEL AND OBTAINING ADDITIONAL  ENGINEERING  PERSONNEL.
The Company is dependent  upon the experience and services of Philip H. Coelho,
President and Chief Executive  Officer,  and  Charles  de  B.  Griffiths,  Vice
President,  Marketing  and Sales and Walter Ludt, Chief Operating Officer.  The
loss of either person would  adversely  affect  the  Company's operations.  The
Company has obtained key man life insurance covering Mr.  Coelho  in the amount
of $1,000,000 as some protection against this risk.  Furthermore, to  implement
its  new  product  development,  the  Company  will  have to recruit and retain
additional experienced engineers.  There is no assurance  that the Company will
be  able  to  find  and  retain  engineers  required  to  meet its self-imposed
deadlines  for  product  development.   See  "The Company and Recent  Events  -
Employees".

PRODUCT  LIABILITY  AND  UNINSURED  RISKS.   The Company  maintains  a  general
liability policy which includes domestic and foreign product liability coverage
of  $1,000,000  per  occurrence  and  $2,000,000 per  year  in  the  aggregate.
Nevertheless, a partial or completely uninsured claim against the Company could
have  a  material  adverse  effect  on the Company's  financial  condition  and
operations.

NEGATIVE IMPACT ON TRADING VALUE OF COMMON  STOCK.   The  Company has currently
more than 15,834,000 shares outstanding, including the shares registered hereby
on  behalf  of  selling shareholders and excluding shares underlying  warrants,
almost all of which are registered and trading.  Because the trading market for
the Company's common  stock  is  affected by numerous circumstances and events,
the Company can make no prediction on the effect the registration of the shares
of common stock hereby will have on  that  market.   The number of shares being
registered by the Company hereby could have an adverse  effect  on  the trading
value  of  its  Common  Stock  in  general.   See "Description of Securities  -
Registration Obligation".

LACK OF CASH DIVIDENDS.  To date, the Company has  not  paid any cash dividends
on its Common Stock and does not expect to declare or pay  any  cash  or  other
dividends on its Common Stock in the foreseeable future.

                         THE COMPANY AND RECENT EVENTS

    
   
The Company  was  incorporated  in Delaware on September 26, 1986 as Insta Cool
Inc.  of  North America, and subsequently  merged  with  Refrigeration  Systems
International, Inc., a California corporation.  In January of 1995, the Company
changed its  name  to  THERMOGENESIS  CORP. to better reflect the thermodynamic
blood processing segment of the biotechnology industry that it hopes to service
through development of new products.  The  Company  designs  and sells products
and  devices  which  utilize its proprietary thermodynamic technology  for  the
processing of biological  substances  including  the cryopreservation, thawing,
and harvesting of blood components, and to a lesser extent for the preservation
of  perishable foods ("Proprietary Technology").  Historically,  the  Company's
primary  revenues  have been from sales of blood plasma freezers and thawers to
hospitals, blood banks  and  blood transfusion centers.  Currently, the Company
is manufacturing several categories  of  thermodynamic  devices which are being
sold to the blood plasma industry under FDA permission to  market in the United
States. Other potential applications and markets for the Company's  Proprietary
Technology  include  medical  and pharmaceutical applications,  and  industrial
applications.  During the fiscal  years  1988  through  1995,  the  Company has
focused its efforts on research and development and on refining product  design
and application.  The Company has also continuously sought new applications for
its  products  and  technology,  including  the design of a device used for the
intraoperative harvesting of autologous fibrinogen rich cryoprecipitate for use
as  a  hemostatic  agent  or  tissue sealant in certain  surgical  and  medical
procedures.   See  "The  Company and  Recent  Events  -  Current  Products  and
Development Efforts".
<R/>

HISTORICAL

    
   
The Company's strategy is  to develop superior blood processing devices for the
niche blood processing markets  where  new  products  could  quickly  establish
credibility  for  the  Company's  Proprietary Technology.  The Company believed
that by concentrating its products  to  serve  the  blood plasma industry, many
customers,  such  as  the  Red  Cross or other blood transfusion  societies  of
various countries, would validate  the  Company's  Proprietary  Technology  for
rapid freezing of biological substances, more specifically blood plasma.  Early
products which were designed for blood banks and hospitals, have received rapid
510(k)  permission  to  market, and the Company believes that it has achieved a
significant market share  for  those products in the 32 countries in which they
are marketed.  See "Annual Report  on  Form  10-KSB -- Description of Business;
Marketing and Distribution".
<R/>
From 1988 to 1992 the Company's products were  designed  to  transfer  heat  by
causing  heat  transfer  liquids  to directly contact plastic sealed containers
within which resided various blood  components.   Early  product  designs  used
liquids  containing  chloro-flouro-carbons ("CFC") which the Company phased out
in the fall of 1992.   Thereafter,  the  Company  developed an alternative heat
transfer method which automatically interposed a thin flexible membrane between
the heat transfer liquid and biological substances  which  process  allowed for
use of non-CFC based heat transfer liquids.

Principal   products  initially  developed  by  the  Company  and  marketed  to
hospitals, blood banks, and blood transfusion centers consisted of freezers and
thawers for blood  plasma.  The Company continued to design and develop various
freezer models and thawers for expanded applications, and these products remain
the core products of  the Company's current business.  To expand its market and
product use, the Company  changed  the focus of its research and development to
the design of new products that would  be  applied  to  different  applications
within  the  blood  industry,  including  surgical,  pharmaceutical and medical
procedures that utilize freezing and thawing technology  as  part  of  standard
procedures.   See  "The  Company  and  Recent  Events  -  Current  Products and
Development Efforts".

Having  established  a  presence  in markets where the need to freeze and  thaw
blood tissues precisely and rapidly  was  valuable to the customer, the Company
began   to   focus   its   technology   towards  harvesting   fibrinogen   rich

                                        8
<PAGE>
cryoprecipitate from blood for use as a hemostatic  agent  and  tissue adhesive
for medical and surgical use.  Medical literature currently documents important
practical applications for fibrinogen rich cryoprecipitate in thirteen distinct
areas,  including  plastic  surgery, thoracic surgery, cardiovascular  surgery,
orthopaedic  surgery, and ophthalmologic  surgery.   The  Company's  fibrinogen
collecting device  with  its  disposable  container sources the fibrinogen rich
cryoprecipitate from a patient's own blood  ("autologous"),  and  is  unique in
that aspect when compared to current sources of fibrinogen which generally rely
on homologous single donations or pooled plasma.

RECENT FINANCING

In November 1996, the Company completed a private placement raising a total  of
$8,268,006,  before  direct expenses, the net funds of which are being used for
general corporate purposes  that  include,  but  are not limited to, payment of
existing accounts payable and short-term debt, testing  of  products, continued
research and development, preclinical trials, production costs  and  inventory,
advertising  and  promotional materials related to new products in development,
working capital, and  increased  payroll  due  to  the  addition  of  personnel
necessary to bring the new products in development to market.

Assuming  the  exercise  of  all  Warrants  issued  as part of the Units in the
private placement at $3.885 per share, the Company would  receive an additional
$5,353,534,  which  would be used to support general operations  and  continued
research and development for additional products and markets.  The Company does
not, however, anticipate that the Warrants will be exercised immediately, based
on the current trading  price  of  $3.9375  on  March  7,  1997.   See  "Use of
Proceeds".   The  Company will not receive any proceeds from the sale of Common
Stock offered by the  Selling  Stockholders  in this Offering.  See "Summary of
the Offering"; "Selling Stockholders".

As part of the private placement of the Units, the Company granted purchasers a
limited price protection provision for the warrants issued as part of the Units
to mitigate the effect of any potential market  decline in the trading price of
the  Company's  Common  Stock should the Company subsequently  seek  additional
financing at a price below  the  exercise  price of the warrants.  All warrants
issued as part of the Units will expire on November  27, 2003, unless exercised
prior to that date.

RESEARCH AND DEVELOPMENT EFFORTS

As of February 1997, the Company had five unique Class II medical systems under
development,  each  of  which  features  not only a thermodynamic  platform  to
process  blood  products  in  a closed system,  but  use  of  various  sterile,
disposable plastic containers and  applicators  that  come  into direct contact
with  the  blood product.  These disposables must be replaced after  each  use,
thereby transforming  each  sale  of  the  system  into a higher margin revenue
stream  stretching  into the future.  The Company is on  schedule  to  complete
development of the first  two  of  these Class II systems - CryoSeal<trademark>
and  N{2} BioArchive<trademark> - by  July,  1997,  and  has  formed  strategic
business relationships with major medical companies to assist its manufacturing
and marketing  efforts.   The following is a brief summary of the current Class
II medical systems in development.

CRYOSEAL<trademark> SYSTEM.   The CryoSeal<trademark> System is a small, floor-
standing thermodynamic device and  special  blood  processing  container  which
harvests  and  concentrates  adhesive  and clotting proteins and growth factors
from a donor or a surgical patient's own blood for use as intravenous treatment
of clotting protein deficient patients,  or to form a superior hemostatic agent
and tissue sealant which the surgeon can use  to  stop  surface  bleeding, bond
tissues and augment or replace sutures.  This "autologous" biological  adhesive
contains the adhesive and/or clotting proteins -- fibrinogen, fibronectin,  von
Willebrand's Factor, factor VIII, and the clot stabilizing protein, factor XIII
- --  as  well  as  platelet derived growth factors (PDGF).  The Company believes
that the CryoSeal<trademark>  System  will  be  an  effective,  safe  and  less

                                        9

expensive alternative to the current commercial tissue sealant known as "Fibrin
Glue"  which,  the Company estimates has annual sales of $400 million in Europe
and Japan, but which  has never been licensed by the FDA for sale in the United
States.
<R/>

The medical literature  documents  important  practical applications for Fibrin
Glue  in  thirteen  distinct  surgical  areas,  including   plastic,  thoracic,
cardiovascular, orthopaedic, and opthamalogic surgery.  Commercially  available
Fibrin   Glue  predominantly  includes  fibrinogen  proteins  which  have  been
harvested  from  plasma  pooled  from thousands of donors.  Fibrin Glue is sold
outside the United States in kits  which  include  a simple applicator and cost
the hospital $100 to $220 per milliliter, depending  on  the country.  Although
Fibrin Glue sourced from pooled plasma has not yet been licensed by the FDA for
sale in the USA due to concerns over contamination by viruses  such  as HIV and
hepatitis,  The Marketing Research Bureau's Report, "Market Assessment  of  the
Commercial Fibrin  Sealant  Market  in the United States:  1996," estimates the
potential annual U.S. market for such  a biological adhesive to be in excess of
$400 million.  No assurances can be given  that  the  Company  will receive all
required  approvals  of its CryoSeal<trademark> System or that it  will  obtain
significant market share  or revenues from the distribution of its system.  See
"Risk Factors - Dependence  on  New  Markets; Government Regulations Associated
with Products".

The Company believes that there is a significant need for a tissue sealant that
fulfills the surgeon's requirement for  effectiveness  and  ease  of  use while
accommodating the patient's justifiable fear of infection from a pooled  plasma
product.   Each surgical use of the Company's CryoSeal<trademark> System, which
can  produce  8  to   10   ml   of   harvested    clotting   proteins
("CryoSealant<trademark>"),  requires  the  use of two or more of the following
disposables which are integral components to the System:

     CP-1: A sterile, plastic bag set for harvesting  the  proteins  and growth
           factors from the patient's blood plasma.

     SA-1: A   small,   sterile,   hand-held  spray  applicator  for  precisely
           depositing CryoSealant<trademark> on large bleeding wound sites.

     DA-1: A small, sterile, hand-held  plastic  line  or  dot  applicator  for
           precisely  depositing  CryoSealant<trademark>  on  small  or  narrow
           bleeding wound sites.

Preclinical studies with the CryoSeal<trademark> System are now taking place in
the United States and Canada under the direction of Dr. Dean Toriumi, a leading
specialist in reconstructive surgery at the Medical School of the University of
Illinois at Chicago, and Dr. Gail Rock, a leading specialist in hematology  and
coagulation  at  the Ottawa Civic Hospital.  The Company applied to the FDA for
510(k) clearance to  market  its  CryoSeal<trademark>  System  for  the initial
indication  as  a  product  for  the  intravenous treatment of clotting protein
deficient  patients.  The second and more  critical  stage  of  the  regulatory
process will  be  to  submit additional clinical findings to support the use of
the CryoSeal<trademark> System as a topical hemostatic and bonding agent during
surgery.  The Company is  currently  in the process of identifying the specific
surgical protocols which would be the  basis for clinical studies to expand the
approved applications of the CryoSeal<trademark> System.

N{2} BIOARCHIVE<trademark> SYSTEM.  This  System is a highly evolved method for
collecting,  controlled-rate  freezing,  processing,   storing  and  retrieving
biological thermolabile substances such as stem and progenitor  cells, corneas,
heart  valves,  sperm  cells, virus samples, biopsy specimens, cell  lines  and
blood, tissue and saliva  samples  for  DNA  matching.   It  features  a liquid
nitrogen dewar equipped with a robotic insertion and retrieval arm with  remote
optical bar code reading, controlled rate freezing and a computerized inventory
management  system  with  proprietary  disposable  containers  tailored  to the
specific biological item.

The  need  to  accurately  validate  that  the  freezing  rate  and storage and
retrieval of these precious biological tissues is paramount.  For example:

     Both  sperm  banks  and  prospective  mothers  need  to  be sure that  the
     implanted  sperm  has been correctly frozen and stored and then  correctly
     identified and retrieved from the thousands of similar inventory items.

     Both police departments  and  suspects  need  to be assured that DNA-typed
     blood, tissue or saliva samples have been correctly  frozen and stored and
     then correctly identified for forensic purposes.

     Both pathologists and patients need to be assured that biopsy samples have
     been  correctly  frozen  and  stored  and  then  correctly identified  and
     retrieved from the thousands of similar inventory items.

     Both  transplant  surgeons  and  patients  need  to  be assured  that  the
     genetically-typed  stem  cells  for  transplantation have  been  correctly
     frozen and stored and then correctly identified  and  retrieved  from  the
     thousands of similar inventory items.

The first biological substance for which N{2} BioArchive<trademark> disposables
have been designed is stem and progenitor cells from placental blood drawn from
blood  within  the placenta and umbilical cord that is normally discarded after
every birth.  Placental  stem  and  progenitor  cells  have  been identified by
researchers  as  a  superior  replacement  alternative to bone marrow  for  the
reconstitution  of  the immune system.  Recent  articles  in  THE  NEW  ENGLAND
JOURNAL OF MEDICINE verify  the  improvements  in patient mortality that result
from the intrinsic advantages of cord blood stem  cells  over  bone marrow stem
cells.  For example, cord blood stem cells can be easily collected,  frozen and
stored in "banks" for immediate use and cord blood stem cells are more tolerant
of  a  mismatch  resulting  in  lower levels of graft vs. host disease for  the
patient.

For optimum therapeutic benefit,  it will be necessary to harvest and inventory
many thousands of cryopreserved placental  stem cell donations, all genetically
typed.  In cooperation with a pioneer and leading  expert  in  this  field, Dr.
Pablo  Rubinstein  of  the  New  York  Blood  Center  ("NYBC"), the Company has
developed four disposable components that optimize the  marriage  of  stem cell
collection with the N{2} BioArchive<trademark> System:

    HR-1:  A  sterile  plastic  disposable  for  holding  the placenta and
           umbilical  cord to facilitate the harvesting of the stem  cell  rich
           placental blood.

    SCP-1: A sterile  plastic bag set for harvesting and cryopreserving the
           stem  cells  in  a  closed  system  and  transferring  them  to  the
           detachable freezing bag.

     DI-1: A sterile, plastic disposable bag set for optimally preparing the
           frozen stem cells for transfusion.

     PC-1: A small disposable metal container to hold and protect the stem cell
           freezing bag during storage in the N{2} BioArchive<trademark> System
           and subsequent transport to the transplant site.


No  assurances  can be given that  the  Company's   N{2}  BioArchive<trademark>
System will be accepted  by  the  market  as  new  uses  for  the  product  are
implemented.   See  "Risk  Factors  -  Dependence  on  New  Markets; Government
Regulations Associated with Products".

JRC BLOOD SAMPLE STORAGE AND RETRIEVAL SYSTEM.  The JRC System  is  a prototype
long-term storage freezer, computer inventory system and blood sample container
for  use  by  the Japanese Red Cross for storing samples of all blood donations
that occur in Japan  each  year.   The  blood  sample  storage program has been
mandated  by the Japanese government in an effort to comply  with  new  product
liability laws  in Japan.  It is estimated that 6,600,000 blood donations occur
annually.  The Company  shipped  the  prototype  JRC System to Daido-Hoxan, the
Company's  Japanese  distributor, in November 1996 for  tests  and  performance
review.  In February 1997,  Daido  Hoxan  placed  an  order for five (5) of the
systems for installation at the five (5) JRC collection  centers in Hokkaido as
a  pilot  program.  No assurance can be given that the Company's  Blood  Sample
Storage and  Retrieval  System  will ultimately be purchased in quantity by the
Japanese Government.  See "Risk Factors - Dependence on New Markets; Government
Regulations Associated with Products".

A brief description of the other  three  Class II products under varying levels
of development, all of which utilize the same  thermodynamic technology already
refined for the CryoSeal<trademark> System, are listed as follows:

MICROSEAL<trademark> SYSTEM.   MicroSeal<trademark>  is a bench top system that
requires less than 50 ml of blood, drawn in a syringe  to harvest up to 1 ml of
CryoSealant<trademark>  for  the hundreds of thousands of  microsurgeries  that
occur each year that could benefit  from  a  safe,  effective biological tissue
sealant  or  hemostatic  agent,  such as: closing macular  holes  in  the  eye,
minimizing scarring in fallopian tube surgery, sealing excised cataract wounds,
bonding skin flaps in minor cosmetic surgery, and repairing ruptured eardrums.

CRYOFACTOR<trademark> SYSTEM.   The CryoFactor<trademark> System is intended to
harvest a full array of autologous  PDGF  immersed  in  a  solution of adhesive
proteins  from  a  patient's  own blood donation for the treatment  of  chronic
wounds such as diabetic and venous insufficiency ulcers and for the healing and
joining of severed nerves.

CRYOPLATELET<trademark> SYSTEM.  The CryoPlatelet<trademark> System is intended
to  cryopreserve blood platelets  which  retain  their  viability  when  thawed
utilizing   novel   freezing   rates,  proprietary  disposable  containers  and
transfusable,  biodegradable  cryoprotectants.    Currently,  platelets  cannot
successfully be frozen and remain viable, and, unfrozen,  have  a shelf life of
only five (5) days.  As a result, 400,000 bags (10% of total bags  produced  in
the United States) are discarded annually due to outdating.

GOVERNMENT REGULATION

All medical devices marketed after May 28, 1976, the date of the Medical Device
Amendments  to the Food, Drug and Cosmetic Act ("FDCA"), must receive clearance
or approval from  the  FDA, unless exempt by regulation, prior to the marketing
or sale of such products  or  distribution in interstate commerce.  Most of the
Company's product510(k) submission").   This  regulatory  process requires that
the Company demonstrate substantial equivalence to a product  which  was on the
market  prior to May 28, 1976, or which has been found substantially equivalent
after that date.  Today, the process of obtaining FDA clearance can be lengthy,
expensive, and generally requires submission of extensive preclinical data and,
in certain  cases, in-use or clinical data, to support a finding of substantial
equivalence.

Under  FDA  regulations,  medical  devices  are  classified  in  one  of  three
categories: Class  I,  Class  II or Class III devices, based on the health risk
posed by such device.  Each class of device must comply with certain regulatory
requirements established by the  FDA  in order to ensure the safe and effective
use of the devices.  Class I devices are  subject  to  General  Controls, which
includes  a good manufacturing practices ("GMP") quality system, labeling,  and
in some instance  510(k) submissions.  Class II devices are also subject to the

                                       12
<PAGE>
General Controls, and in addition must comply with Special Controls established
at the discretion of  the  FDA.   Special  Controls  may include application of
performance and safety standards, product type standards,  clinical  or  in-use
studies,  post-market  surveillance  and  reporting,  and  other FDA guidelines
established at the time of product submission review.  Class  III  devices  are
higher  risk devices that are generally associated with invasive procedures and
must receive FDA pre-market application ("PMA") approval prior to distribution.

The product  development,  preclinical  and  clinical  testing,  manufacturing,
labeling,  distribution,  sales,  marketing, advertising and promotion  of  the
Company's  research,  investigational,  and  medical  devices  are  subject  to
extensive government regulation  in  the  United  States,  and  also  in  other
countries.   Products  manufactured  in  the  United States which have not been
cleared by the FDA through a 510(k) submission, or which have not been approved
through the PMA process, must comply with the requirements  of  Section  801 of
the  FDCA  prior to export.  Class I and Class II devices which are capable  of
being cleared  by the FDA under a 510(k) submission do not require FDA approval
for export; however,  the  Company's  products  must  still comply with certain
safety and quality system requirements in foreign countries  where the products
are proposed to be sold.

Non-compliance   with   applicable  FDA  requirements  can  result  in   fines,
injunctions, civil penalties,  recall  or seizure of products, total or partial
suspension of production, distribution,  sales and marketing, or refusal of the
FDA to grant approval of a PMA or clearance  of  a  510(k).  Actions by the FDA
might also include withdrawal of marketing approvals  and criminal prosecution.
Such  actions could have a material adverse effect on the  Company's  business,
financial condition, and results of operation.

THIRD-PARTY REIMBURSEMENT

In the  United  States,  the  Company's  current  core  product lines of plasma
thawers and freezers, are purchased by community blood banks,  the American Red
Cross  and  hospitals.   The  new  products  in development, however,  will  be
marketed to medical institutions, including hospitals  and  surgi-centers,  and
used  in  surgical  procedures,  the costs for which the institutions will then
seek to have reimbursed by various  third-party payors, such as Medicaid, other
government programs and private insurance  plans.   Third-party payors may deny
reimbursement  if  they  determine  that  the  device or procedure  used  in  a
treatment is unnecessary, inappropriate, experimental  or investigational, used
for  a  non-approved  indication,  or  not  cost-effective in  light  of  other
procedures  available.   Accordingly, determination  of  clinical  benefits  by
physicians is an important  factor  in  the  Company's efforts to bring the new
products  to  market.  Assuming regulatory approval,  the  Company's  perceived
market for its  new  products  in  development  could  be  materially adversely
affected   by   the  failure  of  third-party  payors  to  adopt  policies   of
reimbursement.  In  both the United States and other countries, governments and
third-party payors are  increasingly  challenging  prices  charged  for medical
procedures.    There  can  be  no  assurance  that  reimbursement  for  medical
procedures using  the  Company's  new products in development will be available
or, if available, that the reimbursement rate will continue to be available.

FACILITIES

The Company leases an approximately  17,000  square  foot  facility  in  Rancho
Cordova,  California,   under a lease that terminates in December 2002, subject
to the Company's right to renew for an additional five year term.   The Company
also leases an approximately  11,200  square  foot  facility in Rancho Cordova,
California for manufacturing and production under a lease  that  terminates  in
November  1999.   The Company believes that its current facilities are adequate
to meet its requirements for the next few years.

For a more complete  discussion  of  the  Company  and  its  business and other
properties,  refer  to  the  Company's Annual Report on Form 10-KSB,  which  is
incorporated herein by reference.

<R/>
EMPLOYEES

At fiscal year ended June  30,  1996,  the  Company  employed  fifty-four  (54)
regular  full  time  employees.   In  order to complete research and design, to
build, market and service the new products  in  development,  the Company hired
additional  engineers,  production  personnel,  sales  managers,  and  customer
support, and administrative employees.  At March 1, 1997, the Company  employed
sixty-nine (69) full time employees in the following categories:

          CATEGORY NUMBER
          Research & Design Engineering....................................16
          Production & Manufacturing.......................................27
          Regulatory Affairs & Quality Assurance ...........................4
          Sales & Marketing................................................12
          Finance, Accounting & Administration.............................10

The  Company  considers current staffing levels adequate at this time, but  may
need to add additional  personnel  to  meet  shortened  production  times or to
handle  increases  in business.  Similarly, any downturn in product markets  or
sales might result in decreases in the number of full time employees.

                             SUMMARY OF THE OFFERING

The Company is registering  2,901,589  shares  of Common Stock on behalf of the
Selling Stockholders, and offering 1,478,001 shares  of  Common  Stock upon the
exercise  of  outstanding  Warrants  including  the  placement  agent warrants.
2,756,002  shares  of  Common Stock and the Warrants were issued in  connection
with a November 1996 private  placement by the Company of 1,378,001 Units at $6
per Unit, and the additional 145,587 shares offered were issued pursuant to the
On-Time Manufacturing agreement.   Each  Unit consisted of two shares of Common
Stock and a Warrant to purchase an additional  share  of Common Stock at $3.885
per  share.   To  the extent required under the federal securities  laws,  this
Prospectus may be used  for  resale  of  Common Stock upon the  exercise of the
Warrants by the holders of such Warrants.  See "The Company and Recent Events -
Recent Financing"; "Selling Stockholders".

                                        16
<PAGE>

The Company will receive no proceeds from  the  sale of the 2,901,589 shares of
Common Stock that may be offered and sold from time  to  time  by  the  Selling
Stockholders.

                                 USE OF PROCEEDS

Assuming  Warrants  are  exercised for the purchase of all 1,378,001 shares  of
common stock underlying the  Warrants  issued as part of the Units, the Company
expects  to  receive  $5,353,534  before deducting  expenses  of  approximately
$22,000 associated with this Offering.   In  addition,  if  the placement agent
Warrants to acquire the additional 100,000 shares of Common Stock at $3.885 are
also exercised, the Company will receive an additional $388,500.   The  Company
intends  to  use  any  amounts received from the exercise of these Warrants for
continued research and development projects and for general corporate purposes.
As of March 7, 1997, the  closing  bid  price for one share of Common Stock was
$3.9375.  In light of the current market  price  for one share of Common Stock,
and  the exercise price of the Warrants, it is unlikely  that  a  holder  of  a
Warrant would exercise the Warrant in the immediate future.

                              SELLING STOCKHOLDERS

The following  table  identifies the Selling Stockholders, as of March 5, 1997,
and indicates (i) the nature  of  any  material  relationship that such Selling
Stockholders  have  had with the Company for the past  three  years,  (ii)  the
number of shares of Common  Stock  held  by the Selling Stockholders, (iii) the
amount to be offered for the Selling Stockholders' account, and (iv) the number
of shares and percentage of outstanding shares  of  Common Stock to be owned by
the  Selling Stockholders after the sale of the Common  Stock  offered  by  the
Selling  Stockholders  pursuant to this Offering.  To the extent required under
the federal securities laws,  this  Prospectus may be used for resale of Common
Stock upon the  exercise of the Warrants  by the holders of such Warrants.  The
Selling Stockholders are not obligated to sell  their  Common Stock or Warrants
offered by this Prospectus.

    
   <R/>

    
   
The Company has registered the resale of the Selling Stockholder  Warrants  and
the  Selling Stockholders may sell their Warrants as part of a primary offering
through a private transaction, or may exercise the Warrants and sell the Common
Stock  in  a  secondary offering pursuant to the terms of this Prospectus.  The
table assumes that  the  Selling Stockholders have exercised their Warrants and
will sell the Common Stock in a secondary offering pursuant to this Prospectus.
The Company will receive proceeds  upon  the exercise of the Warrants, but will
not receive any proceeds from the sale of  either  the  Warrants  or the Common
Stock offered pursuant to this Prospectus.  See "Use of Proceeds".
<R/>

    
   
Under the Exchange Act, any person engaged in a distribution of the  shares  of
Common  Stock  of the Company offered by this Prospectus may not simultaneously
engage in market  making  activities  with  respect  to the Common Stock of the
Company  during  the  applicable  periods  prior  to the commencement  of  such
distribution.  In addition, and without limiting the  foregoing,  each  Selling
Stockholder may be subject to applicable provisions of the Exchange Aegulations
thereunder including, without limitation Regulation M.
<R/>

    
   
The  Warrants are not registered or listed for trading on the Nasdaq Market  or
on any  other  exchange.   With  regard  to  the  shares offered by the Selling
Stockholders such shares may be sold on the Nasdaq  Stock  Market or in private
transactions at prices to be determined at the time of sale.   Such  shares may
be offered through broker-dealers, acting on the Selling Stockholders'  behalf,
who  may  offer the shares at then current market prices.  Any sales may be  by
block trade.   The  Selling Stockholders and any brokers, dealers or others who
participate with the Selling Stockholders in the distribution of such shares of
Common Stock may be deemed  to  be  "underwriters"  within  the  meaning of the
Securities  Act, and any commissions or fees received by such persons  and  any
profit on the  resale of such shares purchased by such persons may be deemed to
be underwriting  commissions  or discounts under the Securities Act.  Sales may
be made by all Selling Stockholders  pursuant  to the Registration Statement of
which this Prospectus is a part.

                            DESCRIPTION OF SECURITIES

Pursuant to its Amended and Restated Certificate of Incorporation,  the Company
is authorized to issue two classes of capital stock, designated as Common Stock
and  Preferred  Stock.   The  authorized  Common  Stock  consists of 50,000,000
shares,  $.001  par  value,  and  the  authorized Preferred Stock  consists  of
2,000,000 shares, $.001 par value.

As of February 26, 1997, the number of shares  of  Common Stock outstanding was
15,834,005.   There are no shares of Preferred Stock outstanding.

COMMON STOCK

Holders of shares of the Common Stock have full voting  rights,  one  vote  for
each  share  held  of record.  Subject to preferential rights of holders of any
series of Preferred  Stock,  holders  of shares of Common Stock are entitled to
receive such dividends as may be declared  by  the  Board  of  Directors out of
funds  legally  available therefor, and share pro rata in any distributions  to
stockholders upon  liquidation.   The holders of shares of Common Stock have no
conversion, preemptive or other subscription  rights.   All  of the outstanding
shares  of  Common  Stock are, and the shares offered hereby will  be,  validly
issued, fully paid and nonassessable.

PREFERRED STOCK

The  Company's  Board  of   Directors   is   authorized   to   establish,  upon
authorization,  a  series  or  designation  of  Preferred  Stock  with  rights,
preferences,  privileges,  and  restrictions  on  such  stock  as  the Board of
Directors  may  determine.   The  Company  currently  has  no  Preferred  Stock
outstanding,  and  the  Board  of  Directors  has  not  established any rights,
preferences, privileges or restrictions on such stock.

OPTIONS

As of June 30, 1996, the Company had outstanding options  to  acquire 1,164,333
shares  of  Common  Stock  at exercise prices ranging from $1.64 to  $4.25  per
share.  Some of these options  are  subject  to vesting, and in general, have a
five year exercise period.

WARRANTS

The Company issued warrants to purchase an aggregate of 42,500 shares of Common
Stock  (post  stock  split)  in  connection  with the  private  placement  that
concluded  in  February  1993, of which approximately  17,500  warrants  remain
unexercised.  The remaining  17,500  warrants  may be exercised any time before
February 5, 1998, at an exercise price of $1.20  per share.  The exercise price
may  be  adjusted  from  time to time in the event the  Company  subdivides  or
combines its outstanding Common  Stock.  The Company was obligated to register,
and  did  register  the underlying Common  Stock  of  the  Warrants  under  the
Securities Act, upon the one-time request of  holders of fifty percent (50%) of
those warrants.

As part of the placement  agent's compensation in the 1995 private placement of
Units, additional Warrants  to  purchase  8.8  Units  at  an  exercise price of
$30,000  per  Unit  were  also issued, each Unit consisting of  fifty  thousand
(50,000) shares of Common Stock.

The Company issued Warrants (including the placement agent warrant) to purchase
an aggregate of 1,478,001 shares of Common Stock in connection with the private
placement of Units that was  concluded  in  November 1996.  The Warrants may be
exercised in whole or in part anytime before  November 27, 2003.  The 1,478,001
shares are issuable at an exercise price of $3.885  per  share.   The  exercise
price may be adjusted from time to time in the event the Company subdivides  or
combines  its  outstanding Common Stock. The Company is contractually obligated

                                        20
<PAGE>
to register the  shares  of  Common  Stock  underlying  the  Warrants  with the
Commission  pursuant to the provisions of the Securities Act.  See "The Company
and Recent Events  - Recent Financing".

INVESTOR LOCK-UP

On-Time Manufacturing,  Inc.  was  required  to  enter into an agreement not to
sell, directly or indirectly, the Common Stock included  in  the Offering for a
period  of  180  days following the effective date of a registration  statement
registering its shares for resale.

REGISTRATION OBLIGATION

As part of the private  placement  of the Units, the Company agreed to register
the shares of Common Stock and shares  of  Common Stock underlying the Warrants
issued as part of the Units for resale under  the Securities Act by filing with
the  Commission  a  registration  statement  on Form  S-3,  and  similarly  was
obligated under the contract with On-Time Manufacturing,  Inc.  to register its
shares of common stock  (the "Registration Obligation").  The Company  complied
with  its obligation to file the registration statement.  The Company paid  all
expenses  necessary  to  prepare and file the registration statement.  See "The
Company and Recent Events - Recent Financing".

VOTING RIGHTS; DIVIDENDS

The holders of Common Stock will be entitled to one vote for each share held of
record on each matter submitted  to  a  vote  of  shareholders.   Further,  the
holders  of Common Stock will be entitled to receive ratable dividends when and
as declared  by  the  Board of Directors from funds legally available therefor.
In the event of a liquidation,  dissolution  or  winding up of the Company, the
holders  of  Common  Stock  will be entitled to share  ratably  in  all  assets
remaining after payment to holders  of  any series of preferred stock or of any
other senior securities outstanding at such  time.   It is anticipated that the
Company will not be declaring dividends in the near future.

                     CERTIFICATE OF INCORPORATION AND BYLAWS

The  Company's Amended and Restated Certificate of Incorporation  provides  for
the indemnification  of  directors and officers for certain acts to the fullest
extent  permitted by Delaware  Law.   Further,  the  Company's  bylaws  provide
authority  for  the  Company  to  maintain  a  liability insurance policy which
insures directors or officers against any liability  incurred  by them in their
capacity as such.

Insofar as indemnification for liabilities arising under the Securities Act may
be  permitted  to  directors,  officers and controlling persons of the  Company
pursuant  to the foregoing provisions,  or  otherwise,  the  Company  has  been
advised that  in  the opinion of the Commission such indemnification is against
public  policy  as  expressed   in   the  Securities  Act  and  is,  therefore,
unenforceable.   In the event that a claim  for  indemnification  against  such
liabilities (other than the payment by the Company of expenses incurred or paid
by a director, officer  or  controlling person of the Company 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  Company  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 final adjudication.

                                 TRANSFER AGENT

American  Securities  Transfer  &  Trust,  Inc., 938 Quail Street,  Suite  101,
Lakewood, Colorado 80215-5513, is the transfer  agent  for the Company's Common
Stock.

                       GLOSSARY OF CERTAIN TECHNICAL TERMS


    
   
510(K):  formal notification to the Food and  Drug  Administration  ("FDA")  by
manufacturers  of Class I or Class II devices to obtain clearance to market the
medical device.   The  device  must  be  substantially  equivalent  to  devices
manufactured prior to 1976.

AUTOLOGOUS: autogenous; related to self; originating within an organism itself,
as an autograft or autotransfusion.

CLASS  II  MEDICAL  SYSTEM:  those devices for which general controls alone are
insufficient  to  assure safety  and  effectiveness  and  for  which  mandatory
performance standards must be developed by the FDA.

COAGULATION: 1) the  process  of clot formation.  2) in surgery, the disruption
of  tissue  by  physical  means  to   form   an   amorphous   residuum,  as  in
electrocoagulation and photocoagulation.

CORE  LINE PRODUCTS: (1) device for the ultra-rapid cryopreservation  of  human
blood plasma, (2) portable device for the ultra-rapid cryopreservation of human
blood plasma,  (3)  device  for the rapid thawing of frozen plasma for hospital
patient care, (4) device for  the  hermetic sealing of blood tissue containers,
(5) "smart" blood collection monitor,  (6)  Vial  BioArchive{TM} System for the
Japanese Red Cross.

CRYOPRECIPITATE: any precipitate that results from  cooling, as cryoglobulin or
antihemophilic factor.

CRYOPRESERVATION: the maintaining of the viability of  excised tissue or organs
by storing at very low temperatures.

CRYOSEAL{TM}:  system  for  harvesting fibrinogen-rich cryoprecipitate  from  a
donor's blood plasma, a blood  component  that is currently licensed by the FDA
for the treatment of clotting protein deficient patients.

DEWAR:  container which keeps its contents at  a  constant  and  generally  low
temperature  by  means  of  two  external  walls  between  which  a  vacuum  is
maintained.

FACTOR  VIII:  antihemophilic  factor (AHF): a relatively storage-labile factor
participating only in the intrinsic  pathway  of blood coagulation.  Deficiency
of  this  factor,  when  transmitted as a sex-linked  recessive  trait,  causes
classical hemophilia (hemophilia  A).   More  than  one  molecular form of this
factor  has  been  discovered.  Called also antihemophilic globulin  (AHG)  and
antihemophilic factor A.

FACTOR XIII: fibrin  stabilizing factor (FSF): a factor that polymerizes fibrin
monomers so that they become stable and insoluble in urea, thus enabling fibrin
to form a firm blood clot.   Deficiency  of  this  factor  produces  a clinical
hemorrhagic diathesis.  Called also fibrinase and Laki-Lorand factor (LLF). The
inactive  form  is  also  known  as protransglutaminase and the active form  as
transglutaminase.

FIBRONECTIN: an adhesive glycoprotein: one form circulates in plasma, acting as
an opsonin; another is a cell-surface  protein which mediates cellular adhesive
interactions.  Fibronectins are important  in  connective  tissue,  where  they
cross-link to collagen, and they are also involved in aggregation of platelets.
HEMATOLOGY:  that  branch  of medical science which treats of the morphology of
the blood and blood forming tissues.

Item 15.  Indemnification of Directors and Officers

Section  145 of the Delaware General Corporation Law permits indemnification of
directors, officers  and employees of corporations under certain conditions and
subject to certain limitations.   Article  Eighth  of the Company's Amended and
Restated   Certificate   of   Incorporation   contain   provisions    for   the
indemnification  of  its directors and officers to the fullest extent permitted
by law.

Under such law, the Company  is empowered to indemnify any person who was or is
a party or is threatened to be  made  a  party to any proceeding (other than an
action by or in the right of the Company to procure a judgment in its favor) by
reason of the fact that such person is or was an officer, director, employee or
other agent of the Company or its subsidiaries,  against  expenses,  judgments,
fines,  settlements,  and  other  amounts  actually and reasonably incurred  in
connection with such proceeding, if such person  acted  in  good faith and in a
manner  such  person  reasonably  believed to be in the best interests  of  the
Company and, in the case of a criminal  proceeding,  has no reasonable cause to
believe the conduct of such person was unlawful.  In addition,  the Company may
indemnify, subject to certain exceptions, any person who was or is  a  party or
is  threatened  to  be  made  a  party to any threatened, pending, or completed
action by or in the right of the Company  to procure a judgment in its favor by
reason of the fact that such person is or was an officer, director, employee or
other agent of the Company or its subsidiaries,  against  expenses actually and
reasonably incurred by such person in connection with the defense or settlement
of such action if such person acted in good faith and in a  manner  such person
believed  to be in the best interest of the Company and its shareholders.   The
Company may  advance  expenses  incurred  in  defending any proceeding prior to
final disposition upon receipt of an undertaking  by  the  agent  to repay that
amount it shall be determined that the agent is not entitled to indemnification
as authorized.

In  addition,  although  the  Company  does  not  have director's and officer's
insurance, the Company's bylaws provide the Company  authority  to  maintain  a
liability  insurance  policy which insures directogainst any liability incurred
by them in their capacity as such, or arising out of their status as such.  The
Company intends to seek such insurance in the future.

Item 17. Undertakings

(a) The undersigned Company hereby undertakes:

    
   
   (1) To file, during any period in which offers or sales  are  being  made, a
   post-effective amendment to this registration statement:

          (i)  To include any prospectus required by Section (10)(a)(3) of  the
            Securities Act;

          (ii)To  reflect  in  the prospectus any facts or events arising after
            the effective date of  this  Registration  Statement  (or  the most
            recent post-effective amendment thereof) which, individually  or in
            the  aggregate,  represent  a fundamental change in the information
            set forth in this Registration Statement;

          (iii)To include any material information  with respect to the plan of
            distribution   not  previously  disclosed  in   this   Registration
            Statement or any  material  change  to  such  information  in  this
            Registration Statement.

   Provided,  however,  that paragraphs (a)(1)(i) and (a)(1)(ii), above, do not
   apply  if the information  required  to  be  included  in  a  post-effective
   amendment by these paragraphs is contained in periodic reports filed with or
   furnished  by the Registrant pursuant to Section 13 or 15(d) of the Exchange
   Act that are incorporated by reference in this Registration Statement.

   (2) That, for  the purpose of determining any liability under the Securities
   Act,  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.
<R/>
                                       II-3
<PAGE>

    
   
(b)The  undersigned  Registrant  hereby  undertakes  that,  for  purposes  of
   determining  liability  under  the  Securities  Act, each  filing  of  the
   Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
   Exchange  Act  that  is  incorporated  by  reference  in  this  Registration
   Statement shall be deemed to be a new registration statement relating to the
   securities offered herein, and the offering of such securities at  that time
   shall be deemed to be the initial bona fide offering thereof.
<R/>
(c)Insofar as indemnification for liabilities arising under the Securities  Act
   of  1933  may be permitted to directors, officers and controlling persons of
   the Company  pursuant to the foregoing provisions, or otherwise, the Company
   has been advised  that in the opinion of the 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 Company of expenses incurred or
   paid by a director, officer or  controlling  person  of  the  Company 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 Company 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  Securities  Act  and will be
   governed by the final adjudication of such issue.
