PROSPECTUS
                             THERMOGENESIS CORP.
                      3,317,200 shares of Common Stock
                              ($.001 Par Value)

The  3,317,200 shares of Common Stock  of THERMOGENESIS CORP.  ("THERMOGENESIS"
or the  "Company")  being offered (the "Offering") are being offered by certain
stockholders of the Company  (the "Selling Stockholders").  Of the shares being
offered by Selling Stockholders,  2,781,000  shares  were  issued in connection
with the Company's private placements completed in December  1997,  and 536,200
shares  of  Common  Stock  are  issuable  upon exercise of  three-year warrants
(including 258,100 five-year Placement Agent  Warrants)  issued  as part of the
private  placements.   The  shares  of Common Stock and shares of Common  Stock
underlying 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  September 30, 1997 the Company had an
accumulated deficit of $13,650,678.

The shares of Common Stock and shares of Common  Stock  underlying the 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 closing bid price for the Company's Common Stock on January
29, 1998 was $3.125, 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 by the Selling Stockholders.  See "SELLING
STOCKHOLDERS".  Expenses of the Offering, estimated to be $15,000, will be paid
in full by the Company.

       THE COMMON STOCK OFFERED HEREBY INVOLVES A HIGH DEGREE OF RISK.

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  device company that
designs, manufactures and distributes thermodynamic systems which  utilize  its
proprietary  heat  transfer  technology for the and processing and archiving of
blood products and biological  tissues.   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  sold  to blood transfusion services  and  hospitals  under
permission  from the Food and  Drug  Administration  ("FDA").  Other  potential
applications  and  markets  for  the  Company's Proprietary Technology includes
surgical, pharmaceutical, and industrial applications.  Since fiscal year 1988,
the Company focused its efforts on research  and  development and on refinement
of a core line of products for blood banks.  Since Fiscal 1994, the Company has
developed new applications for its technology, including a system that harvests
fibrinogen rich cryoprecipitate from a donor's plasma for use as an intravenous
treatment of clotting protein deficient patients, and  by  some physicians as a
hemostatic agent or tissue sealant in certain surgical and medical procedures.

The principal executive offices of the Company are located at  3146  Gold  Camp
Drive,  Rancho Cordova, California 95670 and its telephone number is (916) 858-
5100.

                                 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 net proceeds of approximately $1,583,600,
which would be  used  for  continued  research and development, and for general
corporate purposes and operations.

                                  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

                                  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  fiscal year ended June 30, 1997, the Company had a
net loss of $4,805,822 on net  sales  of $6,614,044, and an accumulated deficit
at June 30, 1997 of $11,188,750.  See "Annual  Report on Form 10-K -- Financial
Statements".  For the three months ended September  30, 1997, the Company had a
net  loss  of  $2,461,928 on sales of $711,100, and an accumulated  deficit  at
September 30, 1997 of $13,650,678.

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 system for processing  cryoprecipitate  utilizing  a thermodynamic device
and  disposable processing  containers ("CryoSeal<trademark>  System"); (2) and
a  system  for  collecting, processing, controlled-rate freezing and  inventory
management of thermolabile  products  in  liquid  nitrogen utilizing disposable
containers ("N{2} BioArchive<trademark> System").   See  "Annual Report on Form
10-K -- The Company."  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  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.

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  1998
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, or that it would
be obtained on terms favorable  to  the  Company,  if  available.  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".

LACK OF TESTING DATA.  The Company  has  laboratory  testing  for  its CryoSeal
System and its N{2}BioArchive System.  There can be no assurance that  required
clinical  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.

<PAGE>                              4

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") and from comparable agencies in
foreign countries, which may  limit  or  circumscribe  applications for U.S. or
foreign markets in 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 in the United
States, 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, or that regulatory approval will be received  in  all
foreign  countries.    Although  the  standards  established  by  the  FDA  are
generally  more  encompassing,  the  Company's products may also be required to
meet  certain  additional  criteria or receive  certain  approvals  from  other
foreign governments for marketing and sales.  See "Annual Report on Form 10-K -
- - 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 System and the N{2} BioArchive 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-K  --
Description  of Business"; "Risk Factors -- Uncertain  Availability  of  Third-
Party Reimbursement".

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  System  and  N{2}  BioArchive 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.

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.

RISK  OF  SOFTWARE  DEFECTS.  The Company's CryoSeal System and N{2} BioArchive
System currently in final development rely on computer software components that
direct the harvesting  process  of the CryoSeal System, and the controlled-rate
freezing, storage and retrieval robotics  of  the  N{2} BioArchive 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 seven (7) patents,
and has eight (8) patents pending to protect the designs of an additional three
(3) products  which  the Company intends to market.  See "Annual Report on Form
10-K".  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-K -- Description
of Business".

<PAGE>                              5

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,
Chairman and Chief Executive Officer,  and James H. Godsey, President and 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 "Annual Report on Form 10-
K -- 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.   As  of January 2, 1998, the
Company  has  18,751,919  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

The Company was incorporated in Delaware  on September 26, 1986, and in January
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,  harvesting  and  archiving  of  blood  components.
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 markets for the
Company's   proprietary  technology  include  surgical,   pharmaceutical,   and
industrial   applications.   Since  fiscal  year 1988, the Company  focused its
efforts on research and development and refinement  of  a core line of products
for blood banks. Since fiscal 1994, the Company has developed  new applications
for its products and technology, including  a system for harvesting  fibrinogen
rich  cryoprecipitate  from a donor's blood plasma for use in the treatment  of
hemophilia, and by some  physicians  as a hemostatic agent or tissue sealant in
certain surgical and medical procedures.

HISTORICAL

The Company's strategy was 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
510(k) permission to market, and the Company sells either directly  or  through
its  distribution  network in the 32 countries where its products are marketed.
See "Annual Report on Form 10-K".

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.

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
cryoprecipitate from blood for use an intravenous treatment  of hemophilia, and
by  some physicians as a hemostatic agent and tissue adhesive for  medical  and
surgical  use.   Medical  literature  currently  documents  important practical
applications for fibrinogen glues 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 is able to source the fibrinogen rich cryoprecipitate from
a patient's own blood ("autologous") in less  than  one  hour, and is unique in
that aspect when compared to other sources of fibrinogen.

RECENT FINANCING

In December 1997, the Company completed private placements  of shares of Common
Stock,  raising  an  aggregate  of  $6,952,500, before commissions  and  direct
expenses.  As part of the private placements,  the  Company also issued three -
year warrants exercisable at $3.00 per share of Common  Stock  to each investor
in  an amount equal to ten percent of the Shares of Common Stock  purchased  by
that  investor  in  the  private  placement.   The  net  funds from the private
placements 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 in the private placements at $3.00
per share, and exercise  of  the  258,100 Placement Agent Warrants at $3.00 per
share, the Company would receive additional  net  proceeds of $1,583,600, 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  $3.4375  on  January  9, 1998.  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".

All warrants issued  to investors in the private placements may be exercised at
anytime following registration  of  the  underlying shares of Common Stock with
the Commission, and will expire in December  2000,  unless  exercised  prior to
that date, except for the Placement Agent Warrants that will expire in December
2002.

                             SUMMARY OF THE OFFERING

The  Company  is registering 3,317,200 shares of Common Stock on behalf of  the
Selling Stockholders, of which 536,200 shares of Common Stock are being offered
upon the exercise  of  outstanding  warrants,  including  the  Placement  Agent
Warrants.   The  shares  of  Common  Stock  and  the  warrants  were  issued in
connection  with  the  Company's December 1997 private placements at $2.50  per
share, with no additional  compensation  attributed  to  the warrants.   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".

The Company will receive no proceeds from the sale of the 3,317,200  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  536,200 shares of
Common  Stock  underlying  the  warrants issued in the private placements,  the
Company expects to receive $1,593,600 after deducting expenses of approximately
$15,000 associated with this Offering.   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  January 9,
1998,  the average of the high and low bid price for one share of Common  Stock
was $3.4375.   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.

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.

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.

<PAGE>

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 November 12, 1997,  the  Company  had  outstanding  options to purchase a
total of 1,860,432 shares of Common Stock at exercise prices ranging from $1.64
to $5.625 per share, of which options to purchase 1,352,449  were  exercisable.
Some of these options are subject to vesting, and in general, have a  five year
exercise  period.   See  "Annual  Report  on  Form  10-K  -- Notes to Financial
Statements"

WARRANTS

As  of November 12, 1997, warrants to purchase a total of 1,603,001  shares  of
Common Stock were outstanding with exercise prices ranging from $1.20 to $3.885
per share,  all  of which were exercisable.  Of the outstanding warrants, 5,000
warrants exercisable  at  $1.20  per  share  will expire in February 1998.  The
remaining warrants expire in the year 2000 and  in  the year 2003.  See "Annual
Report on Form 10-K -- Notes to Financial Statements".

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.  That lock-up agreement  was extended by On-
Time Manufacturing until May 1998.

REGISTRATION OBLIGATION

As  part  of  the  private placements in December 1997, the Company  agreed  to
register the shares  of  Common Stock and shares of Common Stock underlying the
warrants  issued for resale  under  the  Securities  Act  by  filing  with  the
Commission   a   registration   statement   on   Form  S-3  (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.

<PAGE>                                  13

HEMATOLOGY:  that  branch  of medical science which treats of the morphology of
the blood and blood forming tissues.

HEMOSTATIC: 1) checking the flow of blood; 2) an agent that arrests the flow of
blood.

MACULAR: pertaining to or characterized  by the presence of macules; pertaining
to the macula retinae.

N{2} BIOARCHIVE: system for controlled rate freezing, storage and retrieval and
inventory  management  of  biological  samples   which  require  LN{2}  storage
temperatures, such as placental, stem and progenitor cells.

PIPELINE PRODUCTS: (1) CryoSeal{TM} System, thermodynamic  processor, (2) LN{2}
BioArchive{TM}  System,  computerized  LN{2}  dewar  with  robotic   arm,   (3)
CryoFactor{TM}  System,  thermodynamic  processor, (4) MicroSealant{TM} System,
bench top thermodynamic processor, (5) CryoPlatelet{TM}  System,  thermodynamic
processor.

PLATELET  DERIVED  GROWTH  FACTOR  (PDGF):  a substance contained in the  alpha
granules  of  platelets  and  capable  of inducing  proliferation  of  vascular
endothelial cells, vascular smooth muscle  cells,  fibroblasts  and glia cells;
its action contributes to the repair of damaged vascular walls.

PROGENITOR: a parent or ancestor.

THERMOLABILE:  easily altered or decomposed by heat.

VON  WILLEBRAND'S  FACTOR:  the  attribute  of  Factor  VIII necessary for  the
adhesion of platelets to vascular elements.  Deficiency of  this factor results
in the prolonged bleeding time seen in von Willebrand's disease.
