ITEM 1.  BUSINESS

(a)      General and Historical Development of Business

The company was incorporated in Delaware in July 1986 as InstaCool 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.  ("Company")  to better  reflect  the  thermodynamic  blood
processing  segment  of the  biotechnology  industry  that it hopes  to  service
through  development of new products.  The Company currently designs,  develops,
manufactures,  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.

Historically,  the  Company's  primary  revenues  were from sales of ultra rapid
blood  plasma  freezers  and  thawers  to  hospitals,   blood  banks  and  blood
transfusion  centers  and  plasma  collection  centers  under  US  Food  &  Drug
Administration  ("FDA")  clearance  to market in the United  States.  During the
fiscal years 1988 through 1995,  the Company  focused  research and  development
efforts on the  refinement of product  design for its blood plasma  freezers and
thawers.  During that period,  the Company also sought new  applications for its
technology,   including   the   design  of   micro-manufacturing   systems   for
biopharmaceutical drugs which utilize the Company's thermodynamic  competence in
new medical therapies.

With  accelerated  research and  development  efforts from 1996 to date totaling
approximately  $10  million,  the  Company  completed  development  of  two  new
technology  platforms,  each of which will give rise to multiple medical devices
targeted at a number of different medical and surgical  applications.  These two
technology platforms are viewed by the Company as micro-manufacturing  platforms
capable of producing  biopharmaceutical  drugs composed of stem cells, proteins,
enzymes  or other  blood  components  that  have  therapeutic  applications  for
treatment of human disease.  The two technology platforms are referred to as the
BioArchive(TM)  Platform  and  the  CryoSeal(TM)  Platform.  The  first  product
developed under the BioArchive  Platform,  the BioArchive Stem Cell System,  was
launched  in May  1998,  and the first  product  developed  under  the  CryoSeal
Platform, the CryoSeal AHF System, was launched in September 1999.

The Company's  completion and transfer of those two new technology  platforms to
manufacturing  resulted in a significant  reduction in research and  development
expenses in FY1999 over FY1998.  Continued  research and development  efforts in
early FY2000 will be principally  focused on finalizing  design of the Company's
autologous  thrombin  activation kit (ATAK) for use as a stand-alone product and
as an integral part of the CryoSeal Platform.  Additional efforts were also made
to optimize the manufacturing process and to cut overhead expenses.

In February of 1999,  following FDA 510(K)  clearance of the CryoSeal AHF System
which     micro-manufactures     cryoprecipitated     anti-hemophilic    factors
(cryoprecipitated AHF) from single units of plasma for the intravenous treatment
of  hemophiliacs,  the  Company  prepared  to  initiate  clinical  trials for an
autologous  fibrin glue (AFG) indication for the CryoSeal  Platform  technology.
These  activities  included  hiring  C  L  McIntosh  as  the  Clinical  Research

<PAGE>2


Organization  to lead the clinical  trial effort and preparing the initial draft
of a clinical  protocol  for an I.D.E.  approved  pivotal  trial  utilizing  the
Company's  autologous  fibrin glue as a hemostatic  agent in liver  resectioning
surgery.

Corporate Strategy

The  Company's  strategy  with its blood plasma  freezers  and  thawers,  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 thermodynamic technology. The Company believed that by concentrating
its products to serve the blood component production  industry,  many customers,
such as the American Red Cross or other blood  transfusion  societies of various
countries, would validate the Company's proprietary thermodynamic technology for
rapid  freezing of blood plasma to achieve  higher  yield of the FVIII  protein.
Early  products  received  rapid  510(k)  clearance  to market,  and are sold to
hospitals and blood  component  production  facilities  through a  telemarketing
staff in the United States and through its distribution network in 32 countries.

In 1994,  the Company  recognized  that the blood  plasma  freezing  and thawing
markets were  limited in size,  and also  perceived  the  Company's  proprietary
thermodynamic  technology  could  have  significant  application  in  processing
specific  bio-pharmaceutical  products  derived from single units of human blood
that would compete in significantly larger markets.  After initial research, the
Company began to focus its technology development towards harvesting Factor VIII
and fibrinogen rich  cryoprecipitate from blood plasma for use as an intravenous
treatment  for  hemophilia  and as  one of two  components  in  fibrin  glue,  a
hemostatic  agent and tissue  adhesive for  surgical  use.  Simultaneously,  the
Company embarked on extensive research and development  efforts,  in conjunction
with The New York Blood  Center  ("NYBC") to develop  systems and  processes  to
harvest,   concentrate,   cryopreserve   and   archive   therapeutic   units  of
hematopoietic  stem and  progenitor  cells from  umbilical  cord blood  (donated
following  the healthy  birth of an infant).  Like bone marrow,  stem cells from
umbilical cord blood can be used to  reconstitute a person's  hematopoietic  and
immune system which has been destroyed as a result of intensive chemotherapy and
radiation  resulting from the treatment of diseases,  such as leukemia lymphomas
and various genetic disorders.

In order to effect the new  strategic  direction,  the  Company  needed to spend
significant  amounts of money in order to fund the research and  development  of
these  two  technology  platforms,  and to  build  a  solid  infrastructure  and
management  team to move the  Company  through  its next  stage of  growth.  The
Company,  with only limited  revenues  generated  from  operations  in the blood
plasma freezer and thawer industry,  was forced to seek financing through equity
transactions  on  several  occasions  in order to fully  fund the  research  and
development  efforts and the  infrastructure  needed to manufacture FDA class II
medical   devices.   Research  and   development   on  the  first  two  platform
technologies,  and development of the first two products under those  platforms,
was  completed  by the end of fiscal year 1998.  During  fiscal  year 1999,  the
Company continued to significantly  restructure its operations and management in
order to prepare for the market  launch in the United States of the CryoSeal AHF
System in 1st Quarter of FY2000,  and the European Market launch of the CryoSeal
AFG System in 2nd half of  FY2000,  in order to  compete  in new  markets  where
annual world-wide revenues are estimated at approximately $400 million.

By June 30, 1999, the Company completed  development of its autologous  thrombin
activation kit, called ATAK, which will serve as both a stand-alone  product and
also an  integrated  component  of the CryoSeal  AFG  System's  CP-2  processing

<PAGE>3


disposable  to  enable  the  CP-2 to  perform  simultaneous  harvesting  of both
fibrinogen  and  thrombin  from a unit of donor  blood to create  an  autologous
fibrin glue (AFG).  Following this  development,  the Company executed a license
agreement  with its  strategic  partner,  ASAHI  MEDICAL CO. LTD. in Japan.  The
Company now believes it is the only  competitor in the $400 million  fibrin glue
industry to develop a totally  autologous  fibrin glue system.  The CryoSeal AFG
System and ATAK product are in final design phase,  and must be approved through
the pre-market  approval  (PMA) process at the FDA, which will include  clinical
trials.

The   CryoSeal  AHF  System,   which   produces   Antihemophiliac   Factor  VIII
(Cryoprecipitated  AHF) for the  treatment  of  hemophilia,  received FDA 510(K)
clearance  in  February of 1999.  Formal  sales  activities  were  initiated  in
September 1999.

Finally,  the  Company  developed  the first  major  upgrade to its Ultra  Rapid
Freezer  line with the  introduction  of the  MicroCascade(TM)  MP1100  integral
freezer that further raised the bar of rapid plasma freezing  performance across
the  transfusion  industry.  The enhanced  performance  is expected to stimulate
upgrade sales in the domestic ultra rapid plasma freezer market.

Following the successful  launch of the BioArchive Stem Cell System in May 1998,
the  Company  placed an additional nine (9)  systems  during  Fiscal Year 1999,
bringing its total to 18 systems  operating in 9 countries around the globe, and
one (1) additional system at Daido  Hoxan used for research.  Notable  among the
current year sales were the London Cord Blood Bank,  the Leuven Cord Blood Bank,
Belgium,  the Institute of  Hematology,  Tianjin,  China,  and Nihon  University
Medical Center,  Japan.  Important  developments in this new market included the
validation  and  production  startup at key  centers  such as the New York Blood
Center,  Duke's  Carolinas  Cord Blood  Bank,  Barcelona's  Institut  de Recerca
Oncologica,  Georgetown University Medical Center, University of Dusseldorf, and
the Finnish Red Cross. Also of importance was Duke University's acquisition of a
second  BioArchive  System in order to  validate  and  utilize the system in the
cryopreservation  of  peripheral  blood (PB) stem cells,  an endeavor that could
significantly  expand the  potential  market  for the  BioArchive  System.  This
clinical  study  received IRB approval at Duke in August 1999 and is expected to
be completed by February 2000.

The  Company  is  now  actively  pursuing   strategic   alliance  partners  with
considerably greater financial and marketing resources than the Company in order
to maximize the commercial value of ATAK, CryoSeal and BioArchive  products.  If
the Company is successful in entering into one or more  strategic  partnerships,
the future R&D  activities of the Company will be devoted to the  development of
two new products derived from the CryoSeal and ATAK research programs:  First is
the  MicroSeal  AFG System which is a  miniaturized  version of the CryoSeal AFG
System for the treatment of outpatient  (ambulatory) wound care.  Beginning with
the reforms in Medicare in the early 1980s and accelerating  with the efforts to
reduce  healthcare  costs in the early  1990s and the  substantial  advances  in
minimally invasive surgery  techniques,  the incidences of outpatient  surgeries
have grown dramatically.  According to Center for Disease Control and Prevention
(CDC) data, annual outpatient  surgeries in the U.S.A. have grown from less than
2 million in 1981 to 31.5 million in 1996.  Each year,  surgeries of the nervous
system (1.2 million), eyes (5.3 million),  ears (0.8 million),  nose, mouth, and
pharynx (2 million),  respiratory  system (4.3 million),  cardiovascular  system
(0.9 million),  digestive  system (6.9  million),  urinary system (1.4 million),
female genital organs (1.9 million),  musculoskeletal  system (4.2 million), and
integumentary  system (2.3 million) are occurring with the surgical incision and
subsequent  bleeding  reduced  sufficiently  to allow the patient to go home the
same day. In the United States these surgeries take place in approximately 5,000
hospital based  surgicenters and 1,700 standalone  surgicenters,  as well as the

<PAGE>4


9,000 offices of plastic surgeons, oral and maxillofacial surgeons, reproductive
surgeons and podiatric  surgeons.  The Company has targeted  development  of its
MicroSeal(TM) System for these minimally invasive surgical theatres.

When development is completed, the Company intends that the MicroSeal AFG System
will  be a  small  bench  top  device  with  small  processing  and  applicating
disposables  that will  require  less than 35 ml of blood  drawn in a syringe to
harvest 1 ml of Autologous  Fibrin Glue (AFG) for the millions of microsurgeries
that occur each year that could benefit from a safe, effective biological tissue
sealant or  hemostatic  agent,  such as:  hemostasis  in  endoscopic  surgeries,
sealing arterial  catherizations,  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.

Second  is the  CryoFactor  System  which  relies  upon  the  CryoSeal  Platform
thermodynamic  processing  device and a modified  software and blood  processing
disposable to harvest and concentrate autologous platelet derived growth factors
(APDGF).  The  Company  intends  that the  CryoFactor  system  will be a product
targeted for sale,  through  distributors,  to the chronic wound care centers in
hospitals, stand alone wound care centers, and long term care facilities for the
treatment of chronic dermal wounds such as diabetic, decubitus and venous stasis
ulcers.  The  CryoFactor  System  completed  the  first of a number  of  planned
pre-clinical  tests designed to optimize the  concentration of growth factors in
order to prepare the product for final design future clinical trials.

The significant research and development expenses and general operating expenses
required to support the manufacture, validation and launch of the BioArchive and
CryoSeal  technology  platforms  have  significantly  diminished  the  Company's
working capital.  The Company will need to financially bridge operating expenses
until it receives significant revenues from the sale and distribution of the new
products. It is not uncommon for new medical technologies to take up to one year
to  gain  full  market   acceptance,   and  the  Company  will  need  to  either
significantly  reduce its  infrastructure  and management  functions during this
period of time,  or find  additional  sources of capital to allow it to continue
with its business plan. The Company is now actively pursuing  strategic alliance
partners of  considerably  greater  marketing and financial  resources  than the
Company in order to maximize the commercial  value of these  recently  completed
ATAK,  CryoSeal  and  BioArchive  products as a means of  supporting  full scale
operations.

Medical Needs Driving Development of New Products

The Risks from Non-Autologous Blood Products

Blood-derived products have saved many lives; however, they have also caused the
transmission of many infections.  Blood component  manufacturers  and regulators
face  the  constant  threat  of new  diseases  which  can  evade  current  blood
purification techniques. Sharing of human blood is by its nature risky -- and it
is a risk worth taking only if there are no appropriate alternatives.

An example of  blood-borne  disease  transmission  is  described in the May 1999
issue of  International  Blood/Plasma  News.  It provides a brief  report on the
incidence of liver  cancer in Japan that  bluntly  portrays the long range "time
bomb" nature of blood borne pathogens:


<PAGE>5



         "Some  32,000  people  suffering  from  liver  cancer die every year in
         Japan,  representing the highest per capita rate of any  industrialized
         country,  according to the Japan Society of Hepatology.  Hepatitis B or
         hepatitis C accounts for 90% of Japanese cases of liver cancer, with an
         average 30-year span between infection and manifestation of the cancer.
         The rise in liver cancer incidence is largely attributable to hepatitis
         C  contracted  from  blood  transfusions,  which  can be  traced to the
         establishment  of commercial blood banks after World War II, as well as
         extensive  blood-requiring  surgeries to treat pulmonary  tuberculosis.
         Liver cancer  represents  the second biggest killer among various types
         of tumors  affecting  Japanese men. While  transmission  of hepatitis C
         from infected  blood products has become almost 100%  preventable,  the
         number of liver cancer  cases is  projected  to increase  over the next
         decade among patients  already  long-infected  with  hepatitis  virus."
         (El-Serag H and Mason A. "Rising Incidence of Hepatocellular  Carcinoma
         in the United States." The New England Journal of Medicine. Volume 340,
         No. 10, March 11, 1999; pp. 745-750. Editorial: pp. 798-799)

What should be remembered is that blood  donations  were not routinely  screened
for  hepatitis  C until  1992 and  until  then  the  industry  authorities  were
proclaiming  the blood supply safe.  What is clear from this simple  incident is
that it is  apparent  that  guardians  of the public  health  can be  tragically
misinformed with deadly consequences that can span a half century.

The  hepatitis C outbreak of the 70's and 80's and HIV's  devastating  impact in
the 80's have taught the medical  community  that the world's  blood  supply may
always be at risk to the  emergence of a yet to be discovered  deadly  pathogen.
The 90's witnessed the emergence of numerous new serotypes of hepatitis and HIV,
including anti-viral  resistance strains.  During the 90's, the prion infectious
agent of  Creutzfeldt-Jakob  Disease (CJD) was  comprehensively  identified as a
pathogen of the deadliest  nature (100% mortality  rate).  More  ominously,  new
variant of CJD (nvCJD)  appeared in the early 90's which  attacks  young  adults
rather than the elderly,  and has a drawn out clinical  cycle of several  months
rather than a few weeks.  Animal models have shown that nvCJD can be transmitted
via B  lymphocytes  isolated  from the tonsils and a recent  publication  in the
medical  journal,  Lancet,  has shown that the rate of  confirmed  deaths due to
nvCJD  appeared  to rise  significantly  at the end of  1998.  There is no known
diagnostic screening test for nvCJD, and the incubation period may be as long as
10 years. Unfortunately, if health officials ultimately confirm that this deadly
pathogen has made its way into the world's blood supply and is transferring  the
disease to patients receive the infected blood products,  it will already be too
late. (Will et al. "Deaths from Variant  Creutzfeldt-Jakob  Disease." The Lancet
Interactive (on-line). Volume 353, No. 9157, March 20, 1999)

More  recently a number of  thoughtful  articles  by  research  scientists  have
appeared in clinical  journals  that predict that germs will be discovered to be
the  primary  cause  of  certain  diseases  not  conventionally  believed  to be
connected to infectious pathogens.  Specifically, a number of cancers as well as
heart  disease  have been linked to prior  infections  (often  asymptomatic)  by
various viral and bacterial agents.

The Company  believes that autologous blood products are the only absolute means
of preventing the infection  tragedies  detailed above,  while still  delivering
care that can often only be achieved through blood-based products.

CLINICAL DATA

     I.  CRYOSEAL PLATFORM

     Fibrin glue prepared from cryoprecipitate  harvested by the CryoSeal System
     from single units of blood plasma has undergone ex vivo and in vivo testing
     throughout  its  development  in order to prepare for our pivotal  clinical
     trials for that indication. The system is currently not approved by the FDA
     for uses other than the automated  production of  cryoprecipitated  AHF for
     the treatment of hemophiliacs.

o        Ex-vivo  assays  were  performed  to fully  characterize  the  CryoSeal
         cryoprecipitate  of  Factor  VIII  and  fibrinogen-rich   clotting  and
         adhesive  proteins which determine the tensile and adhesive strength of
         the resulting clot.  These assays of fibrinogen,  Factor VIII and other
         proteins  exceeded AABB  standards for  Cryoprecipitated  AHF and, as a
         result,  the Company  received 510(k)  clearance to market the CryoSeal
         AHF for the intravenous treatment of hemophilia.

o        Ex-vivo  animal  tests were  performed  to determine if the tensile and
         adhesive  strength of the CryoSeal  fibrin clot,  when  activated  with
         thrombin,  which was  comparable  to  competitive  fibrin glues on both
         porous and non-porous tissue surfaces.  Further,  parenchymal air leaks
         in swine lungs were sealed with  CryoSeal  fibrin glue  compared with a
         cyanoacrylate glue.

o        In vivo animal  surgery was  performed  on pigs to implant  skin grafts
         which  demonstrated  that CryoSeal fibrin glue was fully  comparable to
         competitive  fibrin  glues in  bonding  the graft to the wound site and
         achieving graft survival through rapid re-vascularization of the graft.
         Additional in vivo  surgeries  were performed in rats in which CryoSeal
         fibrin glue was  demonstrated  to be superior to matrigel as a fixation
         media for  Scwhann  cells to  stimulate  axonal  growth in the  severed
         spinal cords.

o        Finally,  CryoSeal  fibrin  glue  was  utilized  in  34 in  vivo  human
         surgeries   at  three   different   hospitals,   in  Italy  and  Canada
         (orthopedic,   neuro,  liver,  spine),  which  demonstrated  comparable
         results  compared to  currently  available  fibrin  glues in regards to
         tissue adhesion and hemostasis.

     II.   BIOARCHIVE PLATFORM

         In Vitro Tests The Placental Cord Blood (PCB) stem and progenitor  cell
     processing  bag sets were tested at the Placental  Blood project at the New
     York Blood Center (NYBC),  the world's largest PCB Bank,  where  progenitor
     cell  recoveries were recorded.  The Company  believes that the ninety-five
     percent progenitor cell recoveries  reported by NYBC utilizing the bag sets
     are the highest of any processing system available today.

         In Vivo Tests Patient outcome data derived from patients  receiving PCB
     transplants prepared with these processing bag sets will be provided to the
     FDA by the PCB banks in the United  States.  These centers  include the New
     York Blood Center,  the NIH PCB banks at Duke  University  Medical  Center,
     Georgetown University Medical Center, and the UCLA Medical Center.

<PAGE>7


     Similar patient outcome data will be provided to the appropriate regulatory
     authorities  directly by the PCB Banks in each foreign country in which the
     BioArchive  Systems are in operation.  As of June 30, 1999 those  countries
     included Finland, United Kingdom, Germany, Japan, Spain, Belgium, China and
     Taiwan.

(b)      FACTORS AFFECTING OPERATING RESULTS

Basis of Presentation.  The Company has incurred recurring  operating losses and
has an  accumulated  deficit of  $30,745,189  as of June 30, 1999. The report of
independent  auditors  on the  Company's  June  30,  1999  financial  statements
includes an explanatory  paragraph  indicating there is substantial  doubt about
the Company's ability to continue as a going concern.  The Company believes that
it has  developed a viable plan to address  these  issues and that its plan will
enable the Company to continue as a going concern through the end of fiscal year
2000.   This  plan   includes  the  pursuit  of  increased   revenues  from  the
commercialization of new products,  the consummation of debt or equity financing
or cash infusion through  strategic  partnerships in amounts  sufficient to fund
further growth, the receipt of license fees from strategic alliance partners and
the reduction of certain operating expenses, as necessary.  Although the Company
believes that its plan will be realized, there is no assurance that these events
will occur.  The financial  statements do not include any adjustments to reflect
the uncertainties  related to the recoverability and classification of assets or
the amounts and classification of liabilities that may result from the inability
of the Company to continue as a going concern.

Dependence Upon New Products for Future Growth. Historically,  substantially all
of the Company's  revenue has been from sales of core line products which freeze
or thaw blood  plasma.  Because the Company  expects  this  portion of the blood
plasma market to have limited growth,  the future success of the Company will be
dependent  upon new  applications  of its  technology.  The  Company  intends to
concentrate on developing and marketing  novel  thermodynamic  blood  processing
systems such as: (1) CryoSeal AHF System; (2) CryoSeal AFG System; (3) MicroSeal
AFG System,  (4) CryoFactor  APDGF System (5) BioArchive  Stem Cell System;  (6)
BioArchive  Tissue System.  Although  these six products use technology  evolved
from the Company's core competence, development of these new products represents
a departure from the Company's current core business.  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.

Need for Additional Financing. In light of delays in new product launches during
fiscal year 1999, and 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  will  need to  secure
additional  financing to complete and fully  implement its business  objectives.
Although the Company has developed  relationships  with investment banking firms
and certain  institutional  investors,  no  assurance  can be given that debt or
equity financing will ultimately be available if needed, and if available,  that
it will be obtained on terms favorable to the Company.

Lack of Testing  Data.  The Company has  completed  certain in vitro and in vivo
testing of its CryoSeal AFG Systems,  and further  clinical studies are to begin
in the near  future in Italy,  Japan,  Canada,  and the United  States  with the
CryoSeal AFG System.  Other in vitro studies have  occurred with the  BioArchive
Stem Cell  System.  However,  all of these  studies,  do not  provide a basis to
achieve  regulatory  permission to promote these systems for all the indications
that  management  believes can be  achieved.  Further  clinical  studies must be
performed.  There  can  be  no  assurance  that  the  clinical  studies  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

<PAGE>8


results of operation could be adversely affected.

Government  Regulation  Associated with Products.  The majority of the Company's
products require  clearance to market from the FDA for sale in the United States
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
or  permission  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.

Dependence on Key  Personnel.  The Company is dependent  upon the experience and
services of Philip H. Coelho, Chairman and Chief Executive Officer, and James H.
Godsey, Ph.D.,  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.

Year 2000 Compliance.  Based upon information  currently  available,  management
does not  anticipate  that the Company will incur  material  costs to update its
computer  software  programs and applications to be "Year 2000"  compliant.  The
Year 2000 problem which is common to most corporations concerns the inability of
information systems, primarily computer software programs, to properly recognize
and process date sensitive information as the year 2000 approaches.  The Company
has completed an assessment of its internal  systems and has developed a plan to
address any issues that may arise.  In addition,  the Company has  relationships
with vendors,  customers  and other third parties who rely on computer  software
that may not be Year  2000  compliant.  Many of  these  third  parties,  operate
outside of the U.S. in countries where  compliance  programs may be less further
along than in the U.S. However,  the Company has formed a task force to identify
and address potential year 2000 issues with significant  vendors,  customers and
other third  parties.  In August  1999, a third party  subcontractor  to the FDA
examined the Company's Year 2000  preparedness and noted no areas of significant
concern.

Possible Loss of Nasdaq SmallCap Market Eligibility.  While the Company's Common
Stock is included on the Nasdaq SmallCap  market,  its continued  inclusion will
depend  on the  Company's  ability  to  meet  certain  eligibility  requirements
established for the Nasdaq system.  If the Company's  Common Stock is ineligible
for trading on the Nasdaq  market,  such  Common  Stock may be subject to a rule
under the Securities Exchange Act of 1934 that imposes additional sales practice
requirements  on  broker-dealers  who sell such securities to persons other than
established  customers and accredited  investors  (generally  institutions  with
assets in  excess of  $5,000,000  or  individuals  with a net worth in excess of
$1,000,000 or annual income  exceeding  $200,000 or $300,000  jointly with their
spouse).  For transactions  covered by the rule, the  broker-dealer  must make a
special suitability  determination for the purchaser and receive that purchase's
written  consent to the  transaction  prior to the sale.  The rule may adversely
affect the ability of  broker-dealers  to sell the Company's  Common Stock,  and

<PAGE>9


consequently may limit the public market for and the trading price of the Common
Stock.

(C)      Description of the Business


Overview of the Ultra Rapid Heat Transfer Technology


The Company's Ultra Rapid freezers and thawers use heat transfer liquids, rather
than gases such as air,  carbon dioxide or nitrogen to transfer heat to and from
a biological  substance.  The Company's  patented thin flexible plastic membrane
system is  automatically  interposed  between the heat  transfer  liquid and the
container housing the blood component.  While  flash-freezing blood plasma, this
flexible  membrane  allows the use of a non-toxic,  low-viscosity  silicone heat
transfer liquid to be refrigerated to -40(Degree)C  and pumped into the freezing
chamber in order to achieve a rapid  transfer of heat without  leaving a residue
on the  exterior  surface  of  the  blood  container.  Tests  of the  technology
performed by the Hague Center of the  Netherlands  Red Cross reports that 300 ml
bags of plasma were core frozen in 30 minutes versus 90-120 minutes in air blast
freezers  which  resulted in 18 to 32% more  factor VIII in the  cryoprecipitate
from the frozen plasma.

Further, the flexible membrane freezing technology also allows the plasma bag to
freeze in a vertical  position causing air bubbles to rise to the top surface of
the bag, so that plasma, when frozen, does not get trapped in the ports and lost
when separated from the bags at the plasma  fractionaters -- a notable advantage
over  conventional  freeze  methods  which  require the bags to lay on trays and
freeze on their sides.

In late  Fiscal Year 1999 THE  COMPANY'S  MP1100  MicroCascade,  the first major
upgrade  of the  plasma  freezer  line was  introduced.  The  MicroCascade  is a
breakthrough new refrigeration  technology that provides  radically  accelerated
freezing performance.

The small,  lightweight (100 lbs) integrated MicroCascade  compressor/condenser
utilizing  compact,  light weight  Schroll  compressors  provides  refrigeration
capacity    equivalent   to   a   bulky,    heavy   8hp   conventional    remote
compressor/condenser.  The  advantage  of the  MicroCascade  technology  is that
expensive and inflexible remote condenser  installations are not required.  This
flexibility  allows  laboratories to quickly start up or modify their production
routing by rolling in the  MP1100,  plugging it into the  electrical  outlet and
immediately  begin flash  freezing  plasma.  The MP 1100 freezer was designed to
meet unprecedented performance standards:

     -   Produce  FFP Core  Temperature  of -30oC in less than 20  minutes,  33%
         faster than previous ThermoGenesis' freezers and five times faster than
         competitive air blast freezers.

     -   Operate at a noise level less than 85 DbA.

Management  believes the MP1100  MicroCascade is currently the fastest method of
freezing plasma available to blood component manufacturing centers.

The Company's  plasma and red blood cell thawers utilize  algecide treated water
to rapidly transfer heat through the patented  flexible membrane system into the
frozen blood product.  In thawing tests  performed by Company  engineers,  which
compared the performance of the Company's thawer versus a microwave  thawer,  it

<PAGE>10


was demonstrated  that frozen plasma rose to a transfusible  temperature  (20oC)
faster and more  homogeneously in the  ThermoGenesis  thawer than when thawed in
the microwave thawer.

The  Company's  Ultra Rapid  Freezers  and  Thawers are the premium  performance
products in the market offering to customers clinically significant improvements
in their plasma products.  The Company pioneered the use of liquid heat transfer
media in the blood bank  industry  over ten years ago. This was followed in 1993
by the development of the "flexible  membrane  pocket" as a means to improve the
safety and  convenience of the  technology by eliminating  direct contact of the
heat transfer fluid with the plasma bag.

Today, the Company still maintains the premier technology position in the plasma
freezing market segment,  with competitors offering primarily  30-year-old blast
freezing  (forced air)  technology.  A direct  result of this  advantage was the
Company's  success in establishing a significant  market position in transfusion
societies and blood banks around the globe.

     Freezers

     The Company has five models of freezers  which vary  primarily  by capacity
     and  condenser  type.  The MP 2000 and MP  1000/1100  are  suited for large
     laboratories  running  approximately 750 bags of plasma per day. The MP 750
     and MP 500 are  suited for medium  sized labs  running  250 to 749 bags per
     day.

     Thawers

     The Company has three models of thawers.  They vary  primarily by capacity:
     The MT202 thaws two bags  simultaneously,  and the MT204 and the MT210 four
     and ten bags respectively.

BioArchive Platform Products

The  BioArchive  Stem Cell  System  was the first  product  developed  under the
BioArchive  System  technology  platform.  In  collaboration  with The NYBC, the
Company developed a disposable blood processing bag set which provides a sterile
method for  collecting,  concentrating  and  cryopreserving  stem and progenitor
cells contained in PCB. These life giving stem and progenitor cells are targeted
for  therapeutic  use in  patients  who suffer  from  malignancies  and  genetic
diseases of the blood and immune  system such as  leukemia,  lymphomas,  diverse
inherited   anemias,   immunodeficiencies,    acquired   aplastic   anemia   and
hypoproliferative disorders.

The  BioArchive  Stem Cell  System  features  a robotic  cryogenic  device  that
automatically  freezes,  archives  and manages an  inventory  of up to 3,626 PCB
units of stem and progenitor cells for transplant.  The proprietary  device also
controls  and  records  the  freezing  profile of each PCB  donation in nitrogen
vapor,  after  which  the PCB unit is  robotically  transferred  to a  specified
indexed  location in liquid nitrogen.  The BioArchive  System tracks the storage
address  of each PCB stem  cell  unit and  assures  that  only the  specifically
chosen,  HLA matched PCB unit is retrieved when selected for a human  transplant
recipient  without  exposing the other archived  samples to detrimental  warming
effects.  The PCB stem and progenitor  cell donations are collected,  processed,
cryopreserved and transfused  utilizing three proprietary sterile disposable bag
sets  developed  jointly  by  NYBC  and  the  Company  and  licensed  to  Medsep
Corporation,  a Division of Pall Corp. for  manufacturing  and  distribution  in

<PAGE>11


North America & Europe. The Company re-acquired the rights to distribute the bag
sets under its own name throughout the rest of the world, except Japan.

PCB stem and progenitor cell  transplants are a viable and preferable  treatment
to bone marrow transplants.  Extraction of bone marrow is expensive, painful and
time consuming for the donor. More significantly,  there are an estimated 10,000
to 15,000 patients turned away for transplants  each year due to an inability to
find a suitably matched bone marrow donor. Further,  there is a significant risk
that a bone marrow  transplant will cause a condition in the transplant  patient
called Graft vs. Host Disease  ("GVHD").  The immature nature of stem cells from
umbilical  cord  blood  appear to  result  in a  reduced  rate of GVHD and allow
engraftment with less than perfect donor matches.  The collecting of the donated
blood (the cells are  harvested  from the  placenta and  umbilical  cord after a
healthy birth) does not risk either the mother or the infant,  and converts what
once was treated as biological waste into a life giving therapy.  The success of
PCB stem cell transplant procedures utilizing units from the NYBC PCB Bank under
the direction of Dr. Pablo  Rubinstein,  one of the world's  foremost experts in
the area of PCB stem cell  transplants,  has been well documented by articles in
the New England  Journal of Medicine  (NEJM),  the  Proceedings  of the National
Academy of Science (PNAS) and other peer review journals.

The National  Institute of Health,  (NIH),  through the National  Heart,  Lung &
Blood  Institute,  (NHLBI),  has sponsored a $30 million  program to advance PCB
stem cell banking in the United States and has chosen to exclusively utilize the
BioArchive sterile, disposable collection,  processing, freezing and transfusion
bag sets.  These  processing and freezing bag sets are designed for use with the
BioArchive Stem Cell System.  Two of the three NHLBI PCB Banks,  Duke University
Medical Center and Georgetown University,  have already purchased the BioArchive
robotic archive device.

During Fiscal Year 1999, nine (9) more BioArchive Systems were placed,  bringing
the  global  total of units  placed  to 19  systems.  PCB  Banks  acquiring  the
BioArchive  Stem Cell  System in Fiscal  Year 1999  included:  Nihon  University
Medical Center, Japan; GHStem Cell Therapy Center,  Guangzhou,  China, Institute
of Hematology,  Tianjin,  China;  London Cord Blood Bank,  England;  Leuven Cord
Blood Bank,  Belgium.  Based on preliminary  market data available in this newly
emerging market,  the Company  estimates that if the FDA licenses PCB stem cells
in Year 2000 as  anticipated,  and new  disease  categories  such as sickle cell
anemia and  thalyssemia  begin to be treated with PCB stem cell, then as many as
100 PCB banks  will form over the next four  years and a typical  PCB bank could
purchase and operate two to three BioArchive Stem Cell Systems.

An  additional  customer  base for the  BioArchive  System is expected to be the
approximately  400 centers in the United States which  collect and  cryopreserve
autologous  hematopoietic  stem and progenitor cells sourced from the peripheral
blood  (PB) of  patients  with solid  tumors,  such as breast  cancer,  who will
subsequently  undergo  chemotherapy  and radiation.  After this  treatment,  the
rescued cells are returned to the patient to  reconstitute  their  hematopoietic
system.  Duke  University's  acquisition of a second  BioArchive  System for the
purpose of validating the system's capabilities for cryopreserving PB stem cells
places the Company on the verge of opening up a significant  new segment of this
emerging cellular therapy market.


<PAGE>12

    (i)      BioArchive System for Other Biological Products

The Company believes that with minimal modifications,  the BioArchive System and
dedicated  disposables  can be easily  reconfigured  to process  and store other
biological  substances  such as heart  valves,  sperm cells,  human eggs,  virus
samples, biopsy specimens,  cell lines, blood tissue, and saliva samples for DNA
matching. The Company has completed conceptual design of a system to hold 53,000
2 ml cryovials,  the most common storage  container  cryogenic in use around the
world.  The  Company  has  initiated a market  research  program  expected to be
completed by  mid-FY2000  and  finalize  customer  requirements  for this larger
market  opportunity.  FDA  clearance  is not  required  in order to  market  the
BioArchive  System for the processing  and  cryopreservation  of  non-transfused
biological substances.

    (ii)     BioArchive Platform Disposables

In addition to the three bag sets  utilized to collect,  process,  and transfuse
PCB Stem Cells which are  manufactured  and distributed  under license by Medsep
Corporation  (Europe and North  America)  and Nissho Corp  (Japan),  the Company
manufactures  and sells three  additional  disposables for the protection of the
PCB units  during  inter-laboratory  transfers  and  shipment to the  transplant
centers which the Company believes will provide an ongoing revenue stream.

             (a)      Canisters

         The freezing  bag is placed in the canister  before it is frozen and it
         remains  in the  canister  while it is stored in liquid  nitrogen.  The
         thermal  properties  of  the  canister  augment  heat  transfer  during
         freezing  and  physically  protect the unit when it is removed from the
         BioArchive System.

             (b)      Canister Sleeve

         The insulated canister sleeve is inserted into the retrieval  cartridge
         prior to a  specimen  retrieval.  During  the  retrieval  process,  the
         canister is automatically  inserted into the insulated canister sleeve;
         where it  protects  the  contents  of the  canister  from  warming  and
         cushions the canister from physical shocks.

             (c)      Overwrap Bag

         The overwrap bag is formed from -200(degree)C  glass transition plastic
         and   provides  a  possible   secondary   barrier   against   potential
         contamination  by  pathogens  as a result of a leaking or an  otherwise
         contaminated freeze bag also stored in the BioArchive System.

    (iii)    CryoSeal Platform Products

Patients who suffer from wounds or other medical conditions which are treated by
proteins,  enzymes or growth  factors  commonly  sourced from plasma pooled from
thousands of paid individuals have legitimate  concerns  regarding their risk of
infection by blood borne viruses (HIV,  Hepatitis A-H,  etc.),  bacteria  (e.g.,
Staphylococcus  aureus,   Yersinia   enterocolitica,   etc.)  and  prions  (e.g.
Creutzfeldt-Jakob Disease -- CJD and nvCJD).


<PAGE>13


Recent  technologies that seek to manufacture  these same proteins,  enzymes and
growth factors through  recombinant  production  processes  rather than "pooled"
plasma have their own manufacturing and allergic reaction safety risks.

The Company believes that the CryoSeal  Platform products provide a superior and
safer approach to producing  therapeutic  doses of these  proteins,  enzymes and
growth  factors.  Each CryoSeal System is a  micro-manufacturing  platform which
harvests and concentrates  these therapeutic blood components from the patient's
own blood,  or in the case of such  medical  conditions  as  hemophilia,  from a
directed donor.

(a)      CryoSeal AHF System

         The  CryoSeal AHF System  mates the  CryoSeal  device with  proprietary
         computer software and a dedicated blood processing  container (CP-1) to
         harvest  cryoprecipitated  AHF in  less  than  one  hour.  AHF is a FDA
         licensed blood product for the intravenous  treatment of hemophilia and
         is  currently  manufactured  from single units of plasma by blood banks
         over a  period  of two to four  days  using  four  separate  pieces  of
         equipment. The CryoSeal System automatically produces  cryoprecipitated
         AHF from a single unit of plasma,  with  concentrations of clotting and
         adhesive  proteins  significantly  higher than  federal  standards,  in
         approximately one hour.  Internal  management  estimates  indicate that
         approximately  up  to 1  million  units  of  cryoprecipitated  AHF  are
         produced   annually  by  blood  banks  in  the  United  States.   While
         recombinant  blood protein products are prevalent in the United States,
         80% of the world's  hemophiliacs cannot afford these expensive proteins
         and,  consequently,  go untreated in their  lifetime and die at a young
         age ("Blood Transfusion Industry." SG Cowen, October 1998). The Company
         believes  that the  CryoSeal AHF System may provide a lower cost source
         of these  clotting  proteins  and is  positioned  to serve this ignored
         market.

(b)      CryoSeal AFG System

         The  CryoSeal AFG System  mates the  CryoSeal  device with  proprietary
         computer  software,  and a dedicated  processing  disposable  (CP-2) to
         produce  autologous  fibrin glue (AFG) from the surgical  patient's own
         blood  in less  than one  hour.  Fibrin  glue  results  from  combining
         thrombin enzyme with fibrinogen clotting protein.  Surgical applicators
         allow the surgeon to precisely administer the AFG to the internal wound
         site to control surface  bleeding,  bond tissues and augment or replace
         sutures.  Autologous  fibrin glue 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)  which the  Company  believes  provide
         competitive  efficacy to  commercial  fibrin  glues  sourced from blood
         plasma pooled from thousands of paid individuals. Outside of the United
         States,  commercial  fibrin  glues have annual  sales in excess of $400
         million.  Because of the concern of viral contamination from the source
         pooled  plasma it was only recently (May 1998) that the FDA granted its
         first clearance to the commercial fibrin glue, Tisseel(R),  marketed by
         Baxter.

(c)      ATAK (Autologous Thrombin Activation Kit)

         Commercial fibrin glues, used bovine-derived  thrombin to initiate clot
         formation.  Bovine-derived  thrombin  was both  readily  available  and
         inexpensive.  With the  emergence  of nvCJD  which is  believed to have
         passed to humans  who  consume  beef from  cattle  infected  by mad cow

<PAGE>14


         disease,   the  European  Community  has  now  prohibited  the  use  of
         bovine-derived thrombin in commercial fibrin glues. Consequently, those
         fibrin glue manufacturers have begun introducing  thrombin sourced from
         pooled human plasma,  which also introduces risk of contamination  from
         these same  infectious CJD prions as well as lethal human  viruses.  To
         order  to  provide  a  safer  alternative,  the  Company  has  recently
         completed  development of a proprietary  disposable kit for preparing 8
         ml of  autologous  thrombin  ("ATAK")  from  a  ~10ml  aliquot  of  the
         patient's  plasma in as little as 40 minutes.  The Company intends ATAK
         to become a stand-alone  product,  as well as an integrated part of the
         CP-2.  Consequently autologous thrombin will be simultaneously prepared
         from the same unit of plasma used to prepare autologous fibrinogen rich
         cryoprecipitate on the CryoSeal AFG System.

         The  Company  announced  the  licensing  of  the  ATAK  technology  for
         exclusive use in Japan to ASAHI MEDICAL CO. LTD. The Company as well as
         ASAHI both expect to initiate  clinical trials during fiscal year 2000.
         The Company also expects  that sales of the new CP-2  disposable  could
         occur in Europe in fiscal  year 2000.  The  Company  believes it is the
         only competitor to develop a 100% autologous  fibrin glue and therefore
         will possess a significant competitive advantage in a market soon to be
         crowded with numerous pooled plasma-based competitors.

(d)      CryoFactor APDGF System

         The  CryoFactor  APDGF  System is  intended  to harvest a full array of
         autologous  platelet  derived growth factors  immersed in a solution of
         adhesive proteins from a patient's own blood donation for the treatment
         of chronic dermal wounds such as diabetic,  decubitus and venous stasis
         skin ulcers.  This growth  factor is produced by the CryoSeal  Platform
         device  (CS-1)  with  modified   software  and  disposable   processing
         containers.  Formal  clinical trials and FDA clearance will be required
         to market the product in the United States.

(e)      MicroSeal AFG System

         MicroSeal AFG is a bench top system that is intended to prepare up to 1
         ml of AFG from  only 35 cc of  patient  blood.  This  volume  of AFG is
         sufficient 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,  repairing
         ruptured eardrums,  sealing vascular stents and providing hemostatis in
         oral  surgeries.  This  system  represents  a  miniaturization  of  the
         technologies that comprise the CryoSeal AFG System.

    (iv)     CryoSeal System Disposables

Each CryoSeal  System requires the use of single  disposables  which the Company
believes will provide a long term revenue stream for the Company.

             (a)      CryoSeal AHF CP-1

         The CP-1 is the primary  disposable of the CryoSeal System used for the
         preparation  of  cryoprecipitated  AHF.  The CP-1  contains  the plasma
         throughout the freezing,  thawing and rocking  procedures  during which

<PAGE>15


         the  cryoprecipitated  AHF separates from the cryo-poor plasma and then
         concentrates, followed by the cryo-poor plasma transferring back to the
         transfer pack.


         The CP-1 received  510(K)  clearance  for marketing  from the US FDA in
         February 1999 and clearance for sale in Canada in 1998.

             (b)      CryoSeal AFG CP-2

         The CP-2 is the primary  disposable for  simultaneously  preparing both
         components  (fibrinogen  and  thrombin) of the  autologous  fibrin glue
         prepared by the CryoSeal  AFG System.  The CP-2 is similar to the CP-1,
         with  the  addition  of the  disposable  components  of the  autologous
         thrombin  activation  kit (ATAK) used for the extraction and processing
         of autologous thrombin.

             (c)      ATAK

         ATAK is the stand-alone-handheld processing disposable with proprietary
         reagents  for  harvesting  8 ml of  autologous  thrombin  from 10 ml of
         patient plasma.

             (d)      Liquid Medication Dispensers

         The Liquid  Medication  Dispensers  were designed for use in surgery to
         apply two  medications to a surgical site  simultaneously  and in equal
         volumetric proportions.

         The  Liquid  Medication   Dispensers   received  510(k)  clearance  for
         marketing  from the FDA in 1996 and  clearance  for sale in Canada from
         Health Canada in 1998.

             (e)      CryoFactor APDGF CP-3

         The CP-3 is the primary  disposable for  harvesting  and  concentrating
         solutions of platelet derived growth factors from platelet rich plasma.
         The CP-3,  like the CP-2 and  systems  dedicated  for their  use,  will
         require FDA clearance to market in the United  States.  Final  Research
         and  development of this product will be dependent on cash flows during
         Fiscal Year 2000.

             (f)      CryoFactor Patient Kit

         The Patient Kit will be the means by which the  therapeutic  CryoFactor
         APDGF solution is aliquoted into individual  dosages for application by
         the  patient  or home care  specialist.  The design is not at this time
         finalized.  Final  Research  and  development  of this  product will be
         dependent on cash flows during Fiscal Year 2000.

Materials Used in Manufacture of Products

Materials  used to produce the  Company's  products are readily  available  from
numerous sources. Based upon current information from manufacturers, the Company
does not  anticipate  any shortage of supply.  In 1992 the Company  introduced a
replacement   heat   transfer   liquid   and   refrigerant   which  is  free  of
chlorofluoro-carbons  (CFC) for use in the Company's  proprietary  process.  The

<PAGE>16


replacement  chemicals are readily available and the Company does not anticipate
any shortages or constraints on supplies.

In July 1999, TUV Rheinland of North America  performed its annual  surveillance
audit of the Company  pursuant  to  prEN46003,  ISO 9003 and the Medical  Device
Directive  ("MDD").  The  re-certification  attests  to  the  Company's  quality
management  system and  permits  the Company to place the CE mark on its medical
devices  reviewed  during the audit.  The CE mark is essential to continued sale
and  distribution  of the  Company's  products in the  European  Community.  The
CryoSeal CP-1 disposable and BioArchive System technical files were reviewed and
certified in January 1999. The Plasma Thawers and Liquid  Medication  Dispensers
were deemed exempt.

THE MARKET FOR THE ULTRA RAPID LINE PRODUCTS

The Market Need for Freezers and Thawers

Freezers:

Blood banks  preserve  blood and plasma  products  by  freezing  them in sterile
plastic bags and then thawing them before use. Whole blood collected from donors
is further fractioned into its components:  Erythrocyte  concentrates,  platelet
concentrates,  fresh frozen plasma and Cryoprecipitated AHF. Fresh frozen plasma
(FFP) contains the labile as well as the stable  components of the  coagulation,
fibrinolytic,  and  complement  systems;  the  proteins  that  maintain  onoctic
pressure and modulate immunity; and other proteins that have diverse activities.
At specialized plasma  fractionation  facilities,  FFP is further processed into
plasma  derivatives for use in component therapy,  such as albumin,  factor VIII
and IX, antithrombin III, iv immunoglobulins,  etc. The typical uses for FFP are
for direct transfusion,  and in the preparation of Cryoprecipitated AHF. The use
of FFP has  increased  tenfold  within  the past 10 years and  reached  almost 2
million units  annually in the USA. One reason for the growth is the  widespread
acceptance  of  the  concept  of  specialized   component  therapy  rather  than
transfusing whole blood. In fact the use of whole blood is decreasing.

A unit of plasma is defined as the fluid portion of one unit of human blood that
has been  centrifuged to segregate and concentrate the red blood cells (RBC) and
platelets. The plasma fraction is then moved to a satellite bag and frozen solid
at -18(degree)C  (or colder) within 6 hours of collection.  Upon freezing,  this
plasma is labeled FFP. Ultra-rapid freezing through the point of fusion provides
for optimum recovery of labile proteins within FFP.

Conventional  freezing systems rely on air blast freezing;  however, this method
requires a considerable length of time (90-120 minutes) to freeze a unit of FFP.

Rapid  freezing is one of the easiest steps that a blood bank or center can take
to dramatically improve the quality of their processed plasma.  Studies at blood
centers in the Hague (the  Netherlands)  and  Hokkaido  (Japan)  showed that the
Factor VIII protein yield from cryoprecipitate from plasma could be increased by
as much as 18-32% by using a the Company's  ultra-rapid  freezer  instead of the
air blast freezers.

Freezer Market Data

The market for Ultra Rapid  freezers  is  concentrated  within the blood  banks,
blood transfusion centers, and plasma collection centers around the world.

<PAGE>17


The Company  believes  that a blood bank would  typically  require 2-6  freezers
depending on facility size and the level of redundant freezing capacity desired.
The  Company   estimates   that  there  are  about  750  blood  bank  or  plasma
fractionation  facilities  that could require a plasma  freezer in the developed
world;  these  facilities  would utilize an installed base of about 2,500 units.
Assuming an eight-year life cycle for a freezer,  the available annual market is
about 312 units or 12.5% of those in the field.

Another  category of  customer  is the  facilities  where  plasma  fractionators
collect  blood  plasma  from  paid  donors.   These  customers   require  large,
high-capacity  freezers.  There are  approximately 330 such facilities in the US
and Canada.  In fiscal year 1996/7 Centeon,  the world's  largest  fractionator,
purchased 76 MP2000 freezers from the Company for their 32 domestic facilities.

Thawer Market Data

Stored Frozen RBC or FFP require thawing before their transfusion.  A process of
rapid homogenous thawing is desirable so that emergency uses can be quickly met.
Rapid thawing also reduces the time available for loss of labile  proteins (i.e.
- -- FVIII) or growth of bacteria that may have  contaminated  the unit during the
phlebotomy.  Conventional  thawing methods often utilize simple 37(Degree)C open
air water baths which thaw frozen  plasma slowly (i.e.  ~30  minutes),  and were
susceptible  to   contamination   by  airborne   bacteria   requiring   repeated
decontamination of the water to maintain  acceptable  environment and conditions
for thawing. With the advent of the THERMOGENESIS CORP. sealed,  membrane pocket
thawers,  the hospital blood bank can thaw frozen blood plasma in  approximately
ten minutes with substantially reduced maintenance requirements.

Thawers are sold to a wider market than  freezers;  all hospitals  which perform
surgery. The Company believes that there are 5,000 potential thawer customers in
the United  States and another  9,000  customers  around the world.  The typical
thawer customer has two thawers on site.

The Market for the BioArchive System

The BioArchive System has been designed as a  special-purpose  cryo-preservation
system for stem cell units  sourced  from PCB or PB. The  Company  believes  the
market for these storage systems will be predominantly  driven by the demand for
PCB stem cell donations and  transplants in the future.  This is a new and still
emerging market.

Clinical Value of PCB Stem Cells.

The clinical value of PCB  hematopoietic  stem cells has been well documented in
the  treatment  of  leukemias,   lymphomas,   diverse  inherited  anemias,   and
hypoproliferative  stem cell disorders.  (Rubinstein et al.  "Outcomes among 562
recipients  of  placental-blood  transplants  from  unrelated  donors."  The New
England  Journal of  Medicine.  Volume  339,  No. 22,  November  26,  1998;  pp.
1565-1577).  Dr.  Rubinstein's  most recent article analyzes the outcomes of 562
post-100 day placental  cord blood PCB  transplant  recipients and concludes the
following:

o        PCB  transplants  regularly  engraft,  produce  low  rates  of GvHD and
         achieve survival rates comparable to those from unrelated BMT;

o        Cell dose / Kg patient weight is important for timing and incidence of
         engraftment; and

o        HLA compatibility was important for engraftment and survival.

These clinical results make clear that thousands of patients' lives can be saved
each  year  if a  significant  inventory  of PCB  units  is  cryo-preserved  and
archived,  ready for  immediate  transplant as soon as the patient is diagnosed.
Estimates vary, but there is some consensus that a  cryopreserved  PCB inventory
of 1 million  (less than 20% of the 5.6 million  potential  bone  marrow  donors
currently in the international  bone marrow  registries) would provide excellent
Human Leukocyte  Antigen (HLA) matches (6-of-6 or 5-of-6) and high cell doses (>
100 x 109/Kg  body mass) to the tens of  thousands  of patients  annually  which
physicians wish to treat with a stem cell transplant.

<PAGE>19


Transplant candidates could include the patients undergoing autologous stem cell
transplants to treat solid tumor cancers (-e.g.  breast cancer).  Unfortunately,
autologous  transplant  outcomes have not been  superior to untreated  patients.
This patient  population  would now have access to a well-matched  unrelated PCB
unit which could establish a new, rather than previously-defeated, immune system
to resist the  re-emergence of cancer cells not killed by the  chemotherapy  and
radiation treatment.

An equally important benefit of this  large-standing  inventory is that it would
allow the  exploration of the treatment of other major diseases that may well be
cured by stem cell transplants,  such as sickle-cell anemia (80,000 patients per
year) ("Sickle Cell Anemia."  National Heart,  Lung, and Blood Institute  (NIH),
NIH Publication No.  96-4057,  November 1996; p. 2), AIDS (200,000  patients per
year)  ("Surveillance  for AIDS-defining  Opportunistic  Illnesses,  1992-1997."
Morbidity and Mortality Weekly Report:  CDC Surveillance  Summaries.  Volume 48,
No.  SS-2,  April  16,  1999)  and  thalassemia   (600,000  patients  per  year)
("Thalassemia  (Cooley's  Anemia) Clinical  Research  Network."  National Heart,
Lung, and Blood Institute (NIH), RFA HL-99-016,  March 11, 1999). An exploratory
clinical study reported an 81% cure rate for treating  sickle cell anemia with a
stem cell transplant.


PCB Stem Cell Banking


PCB samples  are  collected  by seeking  donations  from  parents at the time of
childbirth.   The  placenta  and  umbilical  cord,  which  previously  had  been
considered  medical waste,  is drained of blood through the umbilical  vein, and
stem cells are concentrated from the placental blood.

In order to achieve an optimum  tissue  match with  patients  of diverse  ethnic
backgrounds,  a large  number of PCB  samples  must be banked,  catalogued,  and
available for retrieval.  Statistical  analysis  suggests that 1 million samples
will provide  sufficient volume and diversity to produce a high cell dose and an
excellent  tissue  match  for 95% of the  world's  patients  who may  require  a
transplant.  These two  factors,  in  combination,  significantly  increase  the
likelihood of patient survival.

The Company expects that the health authorities in most countries will establish
PCB stem cell banks in order to help build this 1 million sample inventory.  The
Company  is aware that more than a dozen PCB banks  already  exist in the United
States and expect more to initiate operation over the next five years.

The Company  believes  that most  collected  PCB  samples  will be stored in the
Company's  BioArchive  Systems.  Given that each  BioArchive  System holds 3,626
samples,   approximately  275  Systems  will  be  required  to  serve  the  full
implementation of the storage program.

The Company  expects that within five years more than 10,000  patients each year
will seek PCB  transplants  from the global  network of PCB banks  utilizing the
BioArchive  Stem Cell System.  These  patients  will be drawn from the following
patient populations  (Scientific  American.  "Twelve Major Cancers."  September,
1996):

Currently,  the total number of hematopoietic  stem cell  transplants  performed
annually in the US and Europe is estimated  to be about  30,000 (Time  Magazine.
"Heroes of Medicine".  Fall 1997 Special Issue. pp. 69-70), and the total number
of people who die while  waiting for a bone marrow  transplant  is about  60,000
(Time Magazine. "Heroes of Medicine". Fall 1997 Special Issue. pp. 69-70).

In addition to those  diseases  listed above for which  hematopoietic  stem cell

PCB vs. other sources of stem cells

There are three practical sources of hematopoietic stem cells for reconstitution
of the blood  manufacturing  ability of the human body: bone marrow,  peripheral
blood, and placental cord blood.  Clinical  consensus is building that placental
cord blood (PCB) is the best source.  See  following  chart  comparing the three
sources:

 One of the major  advantages  with PCB stem  cells is that  they are  harvested
 without  pain  to  the  donor  from  the  placenta   and   umbilical   cord,  a
 normally-discarded  tissue.  Consequently,  harvests  can  take  place  in  all
 hospitals in which babies are born. They can be banked in large numbers for use
 whenever a patient is diagnosed.  Currently  every  industrialized  country has
 announced  plans to operate a PCB bank to provide stem cell therapies for their
 citizens.

THE MARKET FOR THE CRYOSEAL AFG SYSTEM

Fibrin  glues are used by  surgeons  to seal  internal  wounds  and to  generate
hemostasis  during  surgery.  While  sutures and staples will bring tissue edges
together  very  effectively,  they do not have  inherent  sealing  and  clotting
activity.  A 1990  review  article  in the  journal  Transfusion  described  the
motivation  behind  the  Company's  development  of its fibrin  glue  production
system:

         "Despite the development of modern surgical  techniques and improvement
         in  intraoperative  hemostasis,  the search for the perfect  hemostatic
         agent continues.  Technological  advances have included improved suture
         materials,  metallic  staples  and clips,  and a variety of natural and
         synthetic hemostasis agents including collagen products (i.e., collagen
         fleece),  absorbable gelatin sponges, oxidized cellulose, and synthetic
         cyanoacrylate-based  glues.  Fibrin  glue  (fibrin  sealant)  has  been
         advocated by many  surgeons as the material  that best  approaches  the
         ideal operative  sealant.  Abundant reports have appeared,  touting its
         beneficial properties.

         As a naturally occurring and ...  human-derived  product,  the material
         appears to have no tissue toxicity,  promotes a firm seal in seconds to
         minutes,  is reabsorbed  in days to weeks  following  application,  and
         appears to promote  local  tissue  growth and  repair.  The use of this
         material  outside of the United  States,  particularly  in Europe,  has
         flourished.  Its use within the  United  States has lagged  more than a
         decade  behind  that of  Europe,  largely  because of the lack of ready
         access to commercially prepared materials."  (Transfusion,  J.W. Gibble

<PAGE>23


         and P.M. Ness,  "Fibrin flue: The Perfect  Operative  Sealant,"  Volume
         30:8. 1990)

Formed by combining fibrinogen and thrombin, fibrin is completely biodegradable.
It is  both a  hemostatic  (clot-forming)  agent  and a  glue.  Fibrin  is  also
completely  natural  - it is  the  body's  own  acute  tissue  cohesive.  Fibrin
dissolves over the four weeks following  surgery in such a way as to allow blood
to provide  nutrients  and healing  factors to the cut tissue edge,  and nothing
else in the surgeon's armamentarium provides this capability

Fibrin  glues are used today for a wide  variety of surgical  procedures.  These
include the major blood-loss  surgeries of the  cardiovascular,  pulmonary,  and
liver regions.  Fibrin glues are used to seal needle holes, pulmonary leaks, and
to seal slow oozing  wounds.  Fibrin glues provide  excellent  adhesion for skin
graft,  plastic  surgery  procedures,  and sealing the dura to prevent  cerebral
spinal fluid leaks.

Current Market Spending on Fibrin Glues

Accurate  data on the current use of fibrin glues is difficult to obtain,  since
much of the US  market  is in the form of "home  brew"  glues.  Since  these are
non-commercial,  "off-label" products,  there is little formal information about
the topic.

In Europe and Japan,  approved commercial fibrin glues sourced from pooled blood
plasma  have  enjoyed  a  long-term  presence  and  represent  about  90% of the
procedures  utilizing surgical sealants in that market.  These commercial fibrin
glues cost  generally  estimates  $60 to $80 per ml delivered to the wound site.
Given their cost they are typically  purchased in smaller  volumes of about 6 ml
per  procedure.  Management  believes that  commercial  fibrin glues are used in
about 300,000  European and 330,000 Japanese  procedures,  with total commercial
spending on fibrin glues equal to $350 million. Baxter's Tisseel has the largest
share of the European  market and  Centeon's  Beriplast has the largest share of
the Japanese market.

Competition

Many companies  seek to take  advantage of the surgeon's  desire for an internal
surgical glue that will solve the limitations of today's  products.  The Company
is  aware  of nine  other  companies  which  have  developed  or are  developing
commercial  fibrin  glues.  A number of companies are also  exploring  synthetic
glues  for  internal  use.  Most of these  products  are at  various  phases  of
development,  and most have not  received  regulatory  approval to market in the
United States.


DISTRIBUTION CHANNELS

The Company  sells its  medical  products  to blood  banks and  hospitals  in 32
countries  including the Red Cross or Blood  Transfusion  agencies of the United
States, Australia,  Belgium, Canada, Denmark, France, Germany, Japan, Korea, the
Netherlands,  Sweden,  and  Switzerland.  The  following  describes  briefly the
channels of distribution and marketing strategy employed by the Company.


<PAGE>24

    (i)      Blood Plasma Freezers and Thawers

The Company has primarily targeted the blood processing  industry which consists
of  approximately  7,000  hospitals and blood  collection  centers in the United
States and  approximately  20,000 hospitals and blood collection  centers in the
industrial  nations  outside  the United  States.  The  Company  formulated  the
following  marketing  strategy for the distribution and sale of its blood plasma
freezers  and  thawers:  the  United  States  accounts  are  serviced  either by
employees of the Company or a manufacturing  representative and  internationally
by regional manufacturing representatives or distributors. The primary thrust of
the Company's marketing efforts focused on hospitals and blood banks such as the
Red  Cross  or blood  transfusion  agencies  in the  United  States,  Australia,
Belgium,  Canada, Denmark, France, Germany, Japan, Korea,  Netherlands,  Sweden,
and Switzerland.

    (ii)     CryoSeal AHF and AFG Systems

The Company's  strategy for entering each of the key markets for fibrin glue has
been  to  align  itself  with  a  larger  corporate   partner  with  established
distribution   channels  in  the   geographically   targeted  areas  for  market
penetration.  Asahi  Medical  Co.,  Ltd.  was selected for the Japan fibrin glue
market,  and Dideco S.p.A. was selected for the European fibrin glue market. The
Company has initiated efforts to align itself with a domestic partner that would
allow  aggressive  market  penetration  in the United States and the rest of the
world through that company's  distribution  network and channels in the surgical
arena  following  FDA  approval  of  expanded  chains  for use as  fibrin  glue.
Furthermore,  the  Company has taken an interim  step to begin  staffing a small
direct sales force to initiate the market launch of CryoSeal AHF in the domestic
market for treatment of  hemophilia.  Sales into other regions of the world will
be  handled  by  local  distributors,  many of whom  the  Company  has  existing
relationships for other products.

    (iii)    CryoFactor APDGF System

Again,  the sales and  marketing  strategy  will focus on  distribution  through
corporate  partners  on a broad  geographical  basis.  Such a  partner  would be
required to demonstrate established distribution and support channels capable of
reaching the hundreds of independent wound care centers in the United States, as
well as the  hospitals,  primary care centers and general  physicians.  A single
U.S. partner may be more conducive to marketing both the CryoSeal and CryoFactor
Systems to access acute and chronic wound care  facilities in the United States,
but further  evaluation  of market  channels  for those  products  must first be
completed by the  Company.  Foreign  markets  will be  addressed  similar to the
domestic market.  As of June 30, 1999, there were no formal  arrangements in any
market for this future product.

    (iv)     BioArchive System

The Company has established  formal  relationships  with Medsep  Corporation,  a
Division  of  Pall  Corporation  for the  manufacture  and  distribution  of the
disposable  bag sets that are  designed  for use with the  BioArchive  Stem Cell
System,  and  cooperates  with Medsep on marketing  efforts and strategy for all
markets  excluding  Japan.  This arrangement was amended in May of FY99 granting
the Company the right to  distribute  the  disposable  bag sets outside of North
America & Europe under the Company's name. The Company  previously  licensed the
manufacture and distribution of the bag sets in Japan to Nissho Corporation, and
also appointed Daido Hoxan as its exclusive distributor for service and sales of
the  BioArchive  System in Japan.  The  Company  markets the  BioArchive  System
through  distributors  internationally  and  directly  in the  domestic  markets

<PAGE>25


through  contacts  developed  early on during the  initial  efforts in stem cell
research and the subsequent movement to create cord blood stem cell banks.

For  non-stem  cell   applications,   the  Company  ended  its  market  research
relationship with one of North America's largest distributors of liquid nitrogen
and is proceeding to initiate a follow on marketing  study  designed to finalize
the marketing requirements for a new 53,000 capacity (the Stem Cell system has a
capacity of 3,626 cord blood specimens/canisters)  cryovial-based design for the
BioArchive  Platform's  application to the cryopreservation of biological tissue
such as sperm, saliva, heart valves, rare cell lines, fertilized human eggs etc.

RESEARCH AND DEVELOPMENT

As of June 30, 1999,  the Company had completed  development  of two  innovative
technology  platforms,  each of which will give rise to  multiple  products  and
medical  systems.  These systems feature a thermodynamic  platform and companion
sterile,  disposable  plastic  containers and applicators  that come into direct
contact with the blood products.  These disposables must be discarded after each
use,  transforming  each sale of the system into a higher margin  revenue stream
stretching into the future. In FY1999 the Company completed development of three
products  derived from its two new  technology  platforms - CryoSeal AHF System,
CryoSeal AFG System,  and BioArchive  Stem Cell System.  The CryoSeal AHF System
gained FDA  clearance of its 510(K) in February  1999.  The Company has incurred
$2,004,798,  $3,858,077,  and  $3,562,280 for fiscal years ending June 30, 1999,
1998 and 1997, respectively.  The following is a brief summary of the additional
medical products in development.

     ATAK.  The  autologous   thrombin  activation  kit  is  a  small  hand-held
disposable  which harvests 8 ml of thrombin with  anticipated  concentration  of
approximately  80  I.U./ml  from 10 ml of  patient  plasma.  Currently  the only
thrombin  available in the United Status is derived from  "pooled"  bovine blood
which,  due to Factor V impurities,  has been  responsible for numerous  severe,
bleeding  episodes in patients and also suffers from  physician  concerns  about
possible  contamination by infectious  prions or viruses.  The Company estimates
that  thrombin is used by surgeons  about a million  times  annually to spray on
bleeding  tissue to "dry the field" by  clotting  residual  fibrinogen.  This is
separate  from the more well known use of thrombin to combine with  concentrated
fibrinogen in  cryoprecipitated  AHF to form a hospital prepared fibrin glue for
more  powerful  hemostasis  and  tissue  adhesion.  The  Company  announced  the
licensing  of the ATAK  technology  to ASAHI  MEDICAL  CO.  LTD.  for use in the
CryoSeal AFG System. Additional patent applications have been filed covering the
thrombin  technology.  The  CryoSeal AFG System will thus be upgraded to utilize
the  new  CP-2  processing  disposable  which  will  process  and  collect  both
components of fibrin glue.

     CryoFactor APDGF System. The CryoFactor APDGF System is intended to harvest
a full  array of  autologous  platelet  derived  growth  factors  immersed  in a
solution  of  adhesive  proteins  from a patient's  own blood  donation  for the
treatment of chronic  wounds such as diabetic,  decubitus and venous stasis skin
ulcers.  Initial  pre-clinical trials were performed during Fiscal Year 1999 and
continue  into Fiscal Year 2000.  This process led to the formation of extensive
relationships  with the leading  researchers in what is an emerging fast growing
wound care  marketplace - the topical  treatment of chronic dermal wounds.  This
system is expected to enter formal clinical trials in Fiscal Year 2001.

<PAGE>26


     The  MicroSeal  AFG  System.  MicroSeal  will be a  miniaturization  of the
CryoSeal AFG System.  MicroSeal AFG is a bench top device with small  processing
and applicating  disposables that requires less than 50 ml of blood,  drawn in a
syringe to harvest up to 1 ml of  Autologous  Fibrin Glue (AFG) for the millions
of microsurgeries that occur each year that could benefit from a safe, effective
biological tissue sealant or hemostatic agent, such as: hemostasis in endoscopic
surgeries,  sealing arterial  catherizations,  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.

MANUFACTURING

The  Company  has   in-house   manufacturing   capabilities   and  is  currently
manufacturing  approximately seventy to eighty percent of its products for sale.
The Company  believes  that vendors used by the Company are capable of producing
sufficient quantities of all required components.  The Company moved to a larger
11,000  square foot  facility in July 1994 where it has since  consolidated  its
manufacturing  assembly  activities.  In February  1997,  the Company  moved its
sales, marketing and administrative  functions, and its research and development
engineering offices into a 17,400 square foot facility.

The  Company  assembles  its Ultra  Rapid  Plasma  Freezers  and  Thawers at its
facility in Rancho  Cordova,  CA. The company has 5,000 square feet dedicated to
the Ultra Rapid  line.  The Company  believes  that this  capacity is capable of
manufacturing  500 units  per year on a single  shift  basis.  The  Company  has
initiated outsourcing of certain of the assembly tasks it now does itself in the
production of the Ultra Rapid line.

ThermoGenesis   Corp.   assembles   the   BioArchive   hardware   from  multiple
subassemblies  supplied by a wide base of skilled vendors.  However, the Company
manufactures  the  robotic,  barcode-reading  periscope  in its  entirety at the
Rancho  Cordova  facility.  The  Company  believes  that it has the  capacity to
manufacture 48 Systems per year on a single shift basis. The BioArchive overwrap
bag is manufactured by the Company and the canister and foam canister sleeve are
supplied by OEM vendors.

The Company has 3,664 square feet dedicated to the manufacturing of the CryoSeal
CS-1 instrument.  The current allocated manufacturing space can manufacture (96)
ninety  six CS-1  units per year or 8 per  month.  That  space  could  easily be
expanded to provide a two-fold increase in capacity,  and 1 to 2 shifts added to
provide a 4-8 fold increase in capacity.  All key  sub-assemblies  are purchased
from a local  supplier  base which could ramp up  production to meet the various
levels of capacity required by the Company.

The CryoSeal Platform requires three patented disposables, both of which must be
delivered to the customer  sterilized  and ready for use. The Company  currently
uses OEM manufacturers to produce these products.

Products  manufactured  or sold by the Company are warranted  against defects in
manufacture  for a  period  of  12  months  from  shipment  when  used  for  the
equipment's intended purpose,  which warranties exclude consequential damages to
the extent allowed by law.

LICENSES AND DISTRIBUTION RIGHTS

In June 1995,  the  Company  granted  the  Japanese  distribution  rights to its
BioArchive  System and the Vial  BioArchive  System to Daido-Hoxan,  Japan.  The
Company  received  $350,000  for  the  distribution  rights  and  access  to the
necessary  technology.   In  May  of  1999,  the  Company  granted  development,
manufacturing  and  distribution  (Japan and Asia)  rights to Daido  Hoxan for a
downsized version of the BioArchive  System.  The Company is entitled to receive
$300,000,  of which  $135,000 was received in fiscal  1999,  for the  technology
rights and the rights to manufacture  and sell the new "mini"  BioArchive in the
non-Japan and non-Asia marketplace.

In June 1996, the Company  entered into an exclusive  manufacturing  license and
distribution  agreement in Japan for the  CryoSeal  System  (including  the ATAK
technology)  with  Asahi  Medical  Co.,  Ltd.,  of Japan,  a  division  of Asahi
Chemical.  Asahi  Medical is a leading  supplier of  artificial  kidneys,  blood
purification systems and leukocyte removal systems, with annual revenues of $270
million.  Asahi will  manufacture  the CP-1  disposable  bag set,  purchase  the
CryoSeal  System  thermodynamic  processing  device  (CS-1)  and  ST-1  and DT-1
surgical  applicators from the Company,  and market the CryoSeal System in Japan
in return for a license  fee,  a  commitment  to  purchase  the CS-1  device and
related  surgical  applicators from the Company and a 10% royalty on the sale of
the sterile bag set. The Company recognized  $400,000 of revenue for the license
fee in fiscal 1996 and more recently, an additional licensing fee was recognized
as revenue for amending the  original  contract to include the ATAK  technology.
Furthermore,  ASAHI MEDICAL took a significant equity position in the Company as
part of the ATAK licensing agreement.

In March 1997,  the  Company  and NYBC,  as  licensors,  entered  into a license
agreement with Pall  Corporation  and Medsep  Corporation,  a subsidiary of Pall
Corporation,  as  Licensees  through  which Pall  Medsep  became  the  exclusive
world-wide  manufacturer  (excluding Japan) for a system of sterile,  disposable
containers developed by the Company and NYBC for the processing of hematopoietic
stem cells sourced from  placental/umbilical  cord blood ("PCB").  The system is
designed to simplify and  streamline the harvesting of stem cell rich blood from
detached  placenta/umbilical  cords  and  the  concentration,   cryopreservation
(freezing) and  transfusion of the PCB stem cells while  maintaining the highest
stem cell  population and viability  from each PCB donation.  These units of PCB
stem cells will be "banked" in frozen storage for  hematopoietic  reconstitution
of patients  afflicted with such diseases as aplastic anemia,  hypoproliferative
stem and progenitor cell disorders,  leukemia, lymphomas and gaucher disease. In
May of 1999,  the Company and Medsep  amended the  original  agreement,  and the
Company  regained the rights to distribute  the bag sets outside North America &
Europe under the Company's name.

In February 1998, the Company  entered into an Exclusive  European  Distribution
Agreement  with  Dideco,  S.p.A.,  a  former  subsidiary  of Fiat and now a $200
million  division of one of Italy's  first  public  companies.  As  distributor,
Dideco was granted  exclusive  distribution  and service rights for the CryoSeal
System in Europe and certain  countries East of the Ural Mountains that formerly
comprised parts of the Union of Soviet Socialist Republics. Under the agreement,
the Company will manufacture and sell the CryoSeal System and its accessories to
Dideco for distribution in the European Community.

PATENTS

The Company  believes  that patent  protection  is  important  for  products and
potential segments of its current and proposed  business.  The Company currently
holds nine (9) patents,  and has ten (10) patents pending to protect the designs

<PAGE>28


of an additional  four (4) products which the Company  intends to market.  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.

While patents have been issued or are pending, the Company realizes (a) that the
Company will benefit from patents  issued,  if any, only if it is able to market
its products in sufficient  quantities of which there is no assurance;  (b) that
substitutes  for these  patented  items,  if not  already in  existence,  may be
developed;  (c)  that  the  granting  of a patent  is not  determinative  of the
validity of a patent; such validity can be attacked in litigation or the Company
or owner of the patent may be forced to institute  legal  proceedings to enforce
validity;  and  (d)  that  the  costs  of such  litigation,  if  any,  could  be
substantial and could adversely affect the Company.

REGULATION OF BUSINESS

The FDA  regulations  govern  the  Company's  operations  at its  facilities  in
connection  with  the  manufacture  of its  products,  and  govern  the sale and
distribution of those products.  Essentially, 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 products require FDA
clearance through a premarket notification process ("510(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  cGMP  quality  system,   labeling,  and  in  some  instance  510(k)
submissions.  Class II devices are also subject to the 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.

<PAGE>29


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  clearance for
export;  however,  the Company's  products must still comply with certain safety
and quality system requirements.

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.

ENVIRONMENTAL MATTERS

The Company has a  California  Environmental  Protection  Agency  Identification
number for the disposal of biohazardous  waste from its research and development
biolab. The Company does not anticipate that compliance with federal,  state and
local  environmental  protection laws will have a material impact on the Company
or require any material capital expenditures under present regulation.

EMPLOYEES

As of June 30, 1999,  the Company had 74 full time  employees.  The Company also
utilizes  temporary  employees   throughout  the  year  to  address  significant
fluctuations  in orders and product  manufacturing.  The Company has a full time
human resources specialist and considers its employee relations to be good.

Financial Information On Foreign Sales and Domestic Operations and Export Sales

The  Company  has no foreign  manufacturing  operations.  For fiscal  year 1999,
foreign sales were approximately $2,000,000, or 44% percent of net revenues. For
fiscal year 1998, foreign sales were approximately  $2,198,000, or fifty percent
of total  revenues  for the year.  For  fiscal  year  1997,  foreign  sales were
approximately $1,024,000, or fifteen percent of total revenues for the year.


ITEM 2.  DESCRIPTION OF PROPERTIES

In July 1994,  the Company leased an  approximately  11,000 square foot facility
located  in  Rancho  Cordova,   California.   This  facility  is  used  for  the
manufacturing assembly of the Company's medical devices, and was upgraded during
fiscal  year  1997  as  part  of  the  Company's  efforts  to  obtain  ISO  9003

<PAGE>30


certification.  In August 1997,  the Company  extended that lease for 26 months,
and it will expire in January 2002.  Annual lease expense  including common area
maintenance charges is $62,000 for this facility.

In  December  1996,  the  Company  leased an  approximately  17,400  square foot
facility, also located in Rancho Cordova,  California, which is used as the main
administrative  and  sales  office,  and  used  as the  Company's  research  and
development  engineering  office.  This lease expires in December  2001, and the
annual lease expense  including common area maintenance  charges is $192,000 for
this facility.

In May 1997, the Company also leased an approximately 5,000 square foot facility
located adjacent to its  manufacturing  facility in Rancho Cordova,  California.
This facility is used for the  manufacture  of the ultra rapid product line. The
lease  expires in June 2000,  and the average  annual  lease  expense  including
common area maintenance charges is $27,000 for this facility.

In April 1998,  the Company leased an  approximately  2,600 square foot facility
located   adjacent  to  other   manufacturing   operations  in  Rancho  Cordova,
California,  to  accommodate  the  manufacture  and  assembly of the  BioArchive
Systems.  The average  annual lease  expense is $17,000 for this  facility.  The
lease was for an initial  term of one year,  and  continues  on a month to month
basis  thereafter.  The Company intends to end its lease of this facility during
the 1st Quarter of FY2000.

At fiscal year end, the Company did not own or lease any other  facilities,  and
with the exception of short term  warehouse  space leased and utilized from time
to time,  management  believes  that current  facilities  are adequate to handle
current  and  expected  operations,  including  future  growth in the  number of
products manufactured.


ITEM 3.  LEGAL PROCEEDINGS

In  December  1998,  the  Company  was  served  with  a  civil  action  entitled
Metropolitan  Creditors  Service of Sacramento  vs.  THERMOGENESIS  CORPORATION,
Sacramento Superior Court No. 98-AS-05815.  The action allegedly arises from the
Company's vendor relationship with On-Time  Manufacturing,  Inc., and relates to
several invoices totaling  approximately  $90,000 in the aggregate which On-Time
Manufacturing,  Inc.  claimed were owing,  and which were allegedly  assigned to
Metropolitan  Creditors  Service of Sacramento.  The Company disputes the claims
and  filed an  answer  to the  complaint  in  December  1998.  In  August  1999,
Metropolitan  Creditors  Service of Sacramento  sought to amend the Complaint to
include  additional  claims for breach of  contract,  seeking  compensatory  and
consequential  damages  in  excess  of  $1-million.  The  Company  proceeded  to
arbitration  on the claims,  including  the breach of contract  claims,  and the
arbitrator  issued an award of $2,625 to Metropolitan  Creditors  Association on
one invoice not encompassed by the contract, and ruled in the Company's favor on
all other claims. If Metropolitan  Creditors  Service of Sacramento  rejects the
arbitrator's award and elects to proceed to trial in Superior Court, the Company
will vigorously  defend the action as baseless,  and seek recovery of attorney's
fees and costs in defending the action.

The Company's  products are relied upon by medical personnel and lab technicians
as part of  blood  collection  processes  from a  donor,  and in some  instances
treatment  of a patient.  If injury  were to result  from the  operation  of the

<PAGE>31


equipment,  the Company,  along with others, may be sued and, whether or not the
Company is found liable,  it may incur legal expenses  associated with defending
such actions.  The Company carries product liability  insurance in the amount of
$2,000,000, with an umbrella policy of $2,000,000, to help insulate against such
risk. While management of the Company believes that current  insurance  coverage
is sufficient,  there can be no assurance that such coverage will  ultimately be
adequate  to cover  liabilities  which may occur.  Moreover,  the Company may be
unable to obtain  product  liability  insurance  in amounts and on terms that it
finds favorable.


ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

The Company did not submit any  matters to  security  holders  during the fourth
quarter of its last fiscal year ended June 30,  1999.  However,  the Company did
call a Special Meeting of  Shareholders  during the first quarter of the current
fiscal year. The Company submitted 3 proposals to the  Shareholders.  Proposal 1
approved an  amendment  to the  Certificate  of  Incorporation  eliminating  the
repurchase rights of the Series A Convertible Preferred Share Holders.  Proposal
2 approved an amendment to the Certificate of  Incorporation  allowing the Board
to effect a one-for two share consolidation. Proposal 3 approved an amendment to
the  Certificate  of  Incorporation  allowing the Board to effect a one-for-four
share consolidation. Proposal 1 was passed by the Shareholders on July 30, 1999.
Proposals 2 and 3 were passed by the  Shareholders on August 13, 1999. The Board
has not acted on Proposals 2 and 3, and there is no current  intention to effect
either of those proposals.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

CERTAIN  STATEMENTS  CONTAINED IN THIS SECTION AND OTHER PARTS OF THIS REPORT ON
FORM 10-K WHICH ARE NOT HISTORICAL FACTS ARE FORWARD-LOOKING  STATEMENTS AND ARE
SUBJECT TO CERTAIN RISKS AND  UNCERTAINTIES.  THE COMPANY'S  ACTUAL  RESULTS MAY
DIFFER SIGNIFICANTLY FROM THE PROJECTED RESULTS DISCUSSED IN THE FORWARD-LOOKING
STATEMENTS.  FACTORS  THAT MIGHT  AFFECT  ACTUAL  RESULTS  INCLUDE,  BUT ARE NOT
LIMITED  TO,  THOSE  DISCUSSED  IN ITEM 1 --  BUSINESS  -- UNDER THE  SUBSECTION
ENTITLED "FACTORS  AFFECTING  OPERATING  RESULTS" BEGINNING ON PAGE 4, AND OTHER
FACTORS  IDENTIFIED  FROM TIME TO TIME IN THE  COMPANY'S  REPORTS FILED WITH THE
U.S. SECURITIES AND EXCHANGE COMMISSION.

The  following  discussion  should  be read in  conjunction  with the  Company's
financial statements contained in this report.

(a)      Overview

The Company's core business was principally the sale of ultra-rapid blood plasma
freezing and thawing  systems,  until the fourth quarter of fiscal 1998 when the
Company  launched  its  BioArchive  Stem Cell  System.  The  Company's  revenues
previously  have been from sales of its core line blood plasma freezers to blood
banks and blood plasma thawers to hospitals and  transfusion  centers.  All core
line blood plasma  freezer and thawer  products are FDA Class I medical  devices
purchased as capital equipment. In the third quarter of fiscal 1999, the Company
received  clearance from the FDA on the 510(K) of the CryoSeal AHF System.  This
System has a Class II  designation  under  applicable FDA  regulations,  and the
Company  has  incurred  additional  expense  in the  last  two  fiscal  years to
establish the required infrastructure to support manufacture of those systems.

Beginning in late 1993, and with  accelerated  research and development  efforts
from 1996 to date  totaling  approximately  $10 million,  the Company  completed
development of the BioArchive and CryoSeal technology  platforms,  each of which
will give rise to multiple  medical  devices  targeted at a number of  different
medical and surgical  applications.  Also,  the Company spent  approximately  an
additional $1 million on improvements,  upgrades,  additional  accessories,  and
beta test site  support  for the new  products.  To  achieve  completion  of the
development and add experienced executive talent to launch the products and move
the Company to new levels of growth and revenues, considerable capital resources
were used.  The  Company  will most likely  need to seek  additional  short term
capital to fully  execute  on its  business  plan  pending  significant  revenue
recognition from the new products.

The Company  has  incurred  recurring  operating  losses and has an  accumulated
deficit of $30,745,189  as of June 30, 1999. The report of independent  auditors
on the Company's  June 30, 1999  financial  statements  includes an  explanatory
paragraph  indicating there is substantial  doubt about the Company's ability to
continue as a going concern. The Company believes that it has developed a viable
plan to  address  these  issues  and that its plan will  enable  the  Company to
continue  as a going  concern  through  the end of fiscal  year 2000.  This plan

<PAGE>35

includes the realization of revenues from the commercialization of new products,
the  consummation  of debt or equity  financing  in amounts  sufficient  to fund
further growth,  and the reduction of certain  operating  expenses as necessary.
Although  the  Company  believes  that its plan  will be  realized,  there is no
assurance that these events will occur. The financial  statements do not include
any adjustments to reflect the uncertainties  related to the  recoverability and
classification  of assets or the amounts and  classification of liabilities that
may result from the inability of the Company to continue as a going concern.

Management does not anticipate that the Company will incur any material costs to
be "Year  2000"  compliant.  The Year  2000  problem  which  is  common  to most
corporations  concerns the inability of information systems,  primarily computer
software programs,  to properly recognize and process date sensitive information
at year 2000.  The Company has completed an  assessment of its internal  systems
and products and determined that  substantially all of the Company's systems and
products operate using third party software that is compliant,  or operate using
Company product software which is Year 2000 compliant.  The Company has formed a
task force to identify and address  potential year 2000 issues with  significant
vendors,  customers and other third parties. To date, no significant issues have
been identified. In August 1999, a third party subcontractor to the FDA examined
the Company's Y2K preparedness and noted no areas of significant concern.

The Company  has  substantially  completed  its Year 2000  assessments  and will
contact the few remaining  vendors by the end of 1999.  The costs of the project
are anticipated to be immaterial,  and the date on which the Company believes it
will  complete  its  assessment  and  remediation,  if  required,  are  based on
management's  best  estimates,  which are derived  using  assumptions  of future
events,  including  continued  availability  of certain  resources,  third party
certification of any  modifications to third party software,  and other factors.
There can be no  guarantee  that these  estimates  will be  achieved  and actual
results  or costs  could  differ  materially  from those  anticipated.  Specific
factors that might cause such material  differences include, but are not limited
to, the availability and cost of personnel  trained in this area, the ability to
locate,   identify  and  correct  all  relevant   computer  codes,  and  similar
uncertainties.

(b)      Results of Operations

The Years Ended June 30, 1999 and 1998:

The following is  Management's  discussion  and analysis of certain  significant
factors  which have affected the  Company's  financial  condition and results of
operations during the periods included in the accompanying financial statements.

Revenues:

Net  revenues  increased  from  fiscal  1998 to fiscal  1999 by $608,000 or 14%.
BioArchive  product line  revenues  increased  16% or $217,000  from fiscal 1998
primarily  due  to  fulfilling  the  backlog  of  disposables   and  accessories
associated  with the  BioArchive  Systems  which were  shipped  in fiscal  1998.
Non-refundable licensing fees generated $459,000 in revenues in fiscal 1999 from
the  Japanese  distributors  of the  BioArchive  and CryoSeal  systems.  No such
licensing fees were  generated in fiscal 1998. The fiscal 1999 CryoSeal  product
line  revenues,  $112,000,  were  primairly  due to the  purchase  of units  and
disposables  by the Company's key  distributors  in Europe and Japan to initiate

<PAGE>36


fibrin glue evaluations. There were no CryoSeal sales in fiscal 1998.

Although  revenues  generated by the  BioArchive  product line were higher,  the
number of BioArchive  units placed fell by one (10 versus 9) from fiscal 1998 to
fiscal 1999.  This lack of unit sales growth is  attributable to a number of key
factors,   including  the  lengthy  capital   equipment   procurement   process,
governmental  decision making and setting global standards related to government
driven cord blood banking programs in major countries.  Setting global standards
was time  consuming  due to the number and  complexity  of the  procedures  that
needed to be validated in order to begin routine use of stem cells harvested and
preserved  for  therapeutic  use. Most notable in this analysis is the fact that
ThermoGenesis  Corp.  did not lose a single  potential  customer  from its sales
pipeline as a result of the longer than expected purchase timeframe.

Net  revenues  decreased  from  fiscal  1997 to  fiscal  1998 by 34%,  primarily
attributable  directly to slower than expected  introduction  of new products in
fiscal  year 1998,  most  notably  the  CyroSeal  AHF System and the  BioArchive
System,  and due to the one time Centeon  order of  approximately  $4-million in
fiscal  1997.  The Company  has entered  into a service  contract  with  Centeon
covering the blood plasma  freezers sold to it in fiscal 1997.  Revenues for the
service  contract,   which  was  entered  into  in  March  1998,  accounted  for
approximately 2% of sales in fiscal 1998.  Additionally,  fiscal 1998 marked the
first year of BioArchive System sales. Ten BioArchive  Systems comprising 30% of
net sales were  shipped in the second and fourth  quarters.  Of the ten systems,
three were placed in the United States pursuant to IRB approvals, four in Europe
and three in Asia.

Cost of Revenues:

As a  percentage  of  revenues,  the  Company's  cost of revenues  significantly
decreased from 126% in fiscal 1998 to 86% in fiscal 1999. The Company attributes
this  significant  improvement  in gross profit to  extensive  efforts to remove
excess capacity from the  Manufacturing  process and focused efforts on the cost
of  procurement  of raw materials  through  improved  forecasting  and planning.
Additionally,  the impact of the mix of products sold during the year ended June
30, 1999 was more  favorable in that both  BioArchive  disposables  and coreline
spare  parts  revenues   generate  higher  gross  profit  margins  than  margins
historically seen from sales of the freezers and thawers.

The  increase  in cost as a percent of sales from 65% in fiscal  1997 to 126% in
fiscal 1998 was primarily  attributable to the following factors: 1) Labor costs
incurred to ensure the Company meets ISO 9003 quality standards for CE approval;
2) Labor  costs for the  start-up  production  of the  CryoSeal  System  and the
BioArchive  System; 3) Production labor diverted to the continued upgrade of the
manufacturing  process;  and 4) Higher warranty  reserves for Pipe Line Products
used in clinical studies.  Cost of sales peaked in second quarter of fiscal 1998
at 170%,  declined  to 120% for the  third  quarter  of  fiscal  1998 and  again
declined  to 98% in the  fourth  quarter  of fiscal  1998 with the launch of the
BioArchive Stem Cell System.

General and Administrative expenses:

This expense category includes Regulatory,  Finance,  Administration and General
Support departments.

General and  administrative  expenses  increased 37% or $791,000 in fiscal 1999.
The increase was driven  almost  entirely by the  Company's  efforts to build an
organization  which is able to  manufacture,  sell and service  class II medical
devices.   Incremental   expenses   were   attributed  to  the   following:   a)
reclassification of executive salaries from manufacturing and sales of $128,000;
b)an  $83,000  accrual  for a  contingent  liability  associated  with  software
licensing;  c) executive  bonuses  (cash and stock) of $245,000,  d) increase in
aggregate  salaries and benefits of $100,000  primarily due to the fact that two
of the current executives were only present for a portion of FY98, and e) patent
legal fees of $90,000 which were  reclassed  from R&D reflecting the transfer of
the BioArchive and CryoSeal systems to manufacturing.

General and administrative  expenses increased in fiscal 1998 by 56% or $762,584
over those of fiscal  1997.  In  November  1997,  the Company  made  significant
changes  in  senior  management  to  improve  operations,  replacing  the  Chief
Operating Officer and the Director of Manufacturing.  Approximately  $200,000 of
the  increase  in  fiscal  1998 was due to  accrual  of  severance  payments  to
departing  executives and signing bonuses for the new President and the new Vice
President  of  Manufacturing   Operations.   The  additional  increase  is  also
attributable  to expansion of facilities,  personnel and additions to management
that are  required  for the Company to  manufacture  and market Class II medical
devices and achieve ISO 9003 certification.

Selling and Marketing expenses:

This  expense   category   includes  Sales  &  Marketing  and  Customer  service
departments.

Selling and  Marketing  expenses  decreased  26% or $618,000 from fiscal 1998 to
fiscal 1999. The expense decrease was due to management's efforts to align sales
and marketing  investments with product  availability and launch dates, which in
the case of the CryoSeal AHF European launch, were delayed significantly. During
the year, the department was restructured to alter the skill mix in an effort to
increase the focus on marketing,  as well as field service  related  activities.
Expenses  were ramped up during the third and fourth  quarters of fiscal 1999 in
anticipation  of the  domestic  launch of the  CryoSeal AHF System and a greater
focus on international BioArchive sales during early FY2000.

Fiscal 1998 selling and marketing expenses increased by 11% over those of fiscal
1997.  This increase was due to increased  salaries from personnel  added during
fiscal  1997 and the  first  half of  fiscal  1998.  Restructuring  of sales and
marketing  during fiscal year 1998 was designed to bring these  expenses in line
proportionately  with  sales  levels  as well as to  increase  the  focus on the
marketing skills needed for successful launch of new products.

Research and Development expenses:

Research and Development was cut 48% in fiscal 1999. This  significant  decrease
reflects the fact that both technology platforms were completed during

<PAGE>38


the prior year and  transferred  to  manufacturing.  The primary focus of R&D in
fiscal 1999 was the completion of the product  development  phase and initiation
of manufacturing transfer phase of the 100% autologous fibrin glue technology.

Research  and  development  expenses  increased  in fiscal  1998 by only 8% from
fiscal  1997.  This  significantly  smaller  increase  is  attributable  to  the
completion  of final  design  and  initial  transfer  of two new  products  from
research and development to manufacturing towards the end of fiscal year 1998.

Management  believes  that product  development  and  refinement is essential to
maintaining the Company's  market  position.  Therefore,  the Company  considers
these costs as continuing  costs of doing  business.  No assurances can be given
that the products or markets  recently  developed or under  development  will be
successful.

(c)      Liquidity and Capital Resources

The Company has consumed  significant  cash  resources for operating  activities
since its  formation  in 1987,  and more  rapidly in the last three fiscal years
primarily to develop new products and markets. Cash resources were significantly
diminished at the end of fiscal year 1999,  and remaining  resources at year end
are  insufficient to permit the Company to fully execute on its business plan to
move towards FDA clinical  trials on new products,  and may be  insufficient  to
maintain the  infrastructure  and management that the Company deems necessary to
launch the new  products  and move the  Company to its new  growth  levels.  The
Company has undertaken  efforts to locate and secure adequate resources to allow
it to fully execute on its plan, including possible equity and debt financing.

In  fiscal  1997,   the  Company   raised  net  proceeds  in  the  aggregate  of
approximately  $7,956,000 from a warrant exercise and a private  placement.  The
Company used the proceeds to expand the  Company's  facilities,  regulatory  and
manufacturing control functions, and to fund continued R&D. Although the Company
believes  that Core Line  product  operations  might have  resulted in a nominal
profit if R&D expenses and marketing expenses  associated with the new FDA Class
II  products  were  eliminated,  the  Company  believes  that the  significantly
increased  expenses for the new  products,  which are directed at new and larger
markets,  is  essential  to future  growth  and long term  profitability  of the
Company.

In  fiscal  1998,   the  Company   raised  net  proceeds  in  the  aggregate  of
approximately  $6,433,000 net of expenses from private placements of equity. The
Company used the proceeds to complete design validation, manufacturing transfer,
and restructuring to accommodate new product launches.  Management believes that
the losses sustained in the current fiscal year ended were prudent and necessary
for  the  Company  to  realize  the   significant   future  revenue   prospects.
Significantly,  the large losses and operating  expense  trends began to reverse
beginning  in the third  quarter of this fiscal  year as the  Company  initiated
transfer to  manufacturing  and product launch for the BioArchive  System in the
fourth quarter.

In fiscal  1999,  the  Company  raised net  proceeds of  $6,227,000  through the
private  placement of 1,077,540 shares of Series A Convertible  Preferred Stock.
The Company used the proceeds to prepare for the domestic  market  launch of the

<PAGE>39


CryoSeal AHF System,  develop the 100%  autologous  fibrin glue  technology  and
bring in the  resources  necessary  to prepare for the fibrin glue pre  clinical
trials.  Management  believes that the losses  sustained  were necessary for the
Company to  progress on its  strategic  direction  and to  realize  significant
future revenues.  However,  the Company was focused on reducing  expenses during
fiscal 1999,  as  evidenced  by the $3.5 million  reduction in the net loss from
fiscal 1998 to fiscal 1999.

The Company does not require  extensive capital equipment to produce or sell its
current products.  However, when significant capital equipment is required,  the
Company  purchases  from a vendor base or is  pursuing  strategic  partners.  In
fiscal 1997, the Company expended $873,582 for the purchase of capital equipment
and expansion of facilities for operations. In fiscal 1998, the Company expended
$449,092,  the majority of which was for certain test  equipment  and  leasehold
improvements  for the launch of the BioArchive and CryoSeal  Systems.  In fiscal
1999, the Company spent $115,372  primarily for test equipment  associated  with
the BioArchive and CryoSeal  systems and to build a cleanroom to manufacture the
BioArchive  periscope.  Although future capital expenditures may be anticipated,
the Company believes that the amounts expended will be consistent with, or lower
than fiscal 1999.

The Company  continues to search for further  funding and new products  that may
provide  future  growth  opportunities  and is  currently  evaluating  financing
options to provide  working  capital to fund expected growth in fiscal year 2000
with the  domestic  launch  of the  CryoSeal  AHF  System.  The  Company  has no
significant outstanding capital commitments at June 30, 1999.

Currently,  the Company is contemplating additional equity financing to fund the
product launch of the CryoSeal AHF System, and to initiate and complete clinical
trials  and FDA  submissions  for  the  CryoSeal  AFG  System.  There  can be no
assurances that adequate  financing will be available on satisfactory  terms, if
at all. The Company  anticipates that it will need additional  financing to meet
short term  obligations,  or it will be  required  to further  reduce  operating
expenses and possibly certain management  processes  established during the past
year.  Such  reductions  could  significantly  impair future  prospects,  and no
assurances can be made that adequate capital resources will be made available to
the Company in a time frame that will not impair current infrastructure.

Working  capital  increased  from  $3,666,000  at June  30,  1998 to  $5,055,000
primarily due to the cost  reduction  efforts the Company  implemented in fiscal
1999.

Management  does not believe that inflation has had a significant  impact on the
Company's results of operations.

                REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS



The Board of Directors and Shareholders THERMOGENESIS CORP.

We have audited the  accompanying  balance sheets of  THERMOGENESIS  CORP. as of
June 30, 1999 and 1998, and the related statements of operations,  shareholders'
equity,  and cash flows for each of the three years in the period ended June 30,
1999. Our audits also included the financial  statement  schedule  listed in the
Index  at  Item  14(a)(2).  These  financial  statements  and  schedule  are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements and schedule based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects, the financial position of THERMOGENESIS CORP. at June 30,
1999 and 1998,  and the results of its operations and its cash flows for each of
the three years in the period ended June 30, 1999, in conformity  with generally
accepted  accounting  principles.  Also, in our opinion,  the related  financial
statement  schedule,   when  considered  in  relation  to  the  basic  financial
statements  taken as a whole,  presents  fairly  in all  material  respects  the
information set forth therein.

The  accompanying   financial   statements  have  been  prepared  assuming  that
THERMOGENESIS CORP. will continue as a going concern. As more fully described in
Note  1,  the  Company  has  incurred  recurring  operating  losses  and  has an
accumulated  deficit of $30,745,189 as of June 30, 1999.  These conditions raise
substantial  doubt about the Company's  ability to continue as a going  concern.
Management's  plans in regard to these matters are also described in Note 1. The
financial statements do not include any adjustments to reflect the uncertainties
related to the  recoverability  and  classification of assets or the amounts and
classification  of  liabilities  that  may  result  from  the  outcome  of  this
uncertainty.

                          NOTES TO FINANCIAL STATEMENTS


1. Summary of Significant Accounting Policies

Organization and Business

THERMOGENESIS  CORP.  ("the Company") was incorporated in Delaware in July 1986.
The  Company   designs  and  sells  devices   which   utilize  its   proprietary
thermodynamic  technology for the processing of biological  substances including
the cryopreservation,  thawing and harvesting of blood components. During fiscal
1988 through  1999,  the Company has focused on refining  product  design of the
core   line   products   and   developing   a   pipeline   of   two   technology
platforms(BioArchive  and CrySeal Systems) and derivative products which utilize
sterile  disposable  containers for processing blood components.  The BioArchive
system was launched in fiscal 1998.

Basis of Presentation

The Company  has  incurred  recurring  operating  losses and has an  accumulated
deficit of $30,745,189  as of June 30, 1999. The report of independent  auditors
on the Company's  June 30, 1999  financial  statements  includes an  explanatory
paragraph  indicating there is substantial  doubt about the Company's ability to
continue as a going concern. The Company believes that it has developed a viable
plan to  address  these  issues  and that its plan will  enable  the  Company to
continue  as a going  concern  through  the end of fiscal  year 2000.  This plan
includes the realization of revenues from the commercialization of new products,
the  consummation  of debt or equity  financings  in amounts  sufficient to fund
further growth,  and the reduction of certain  operating  expenses as necessary.
Although  the  Company  believes  that its plan  will be  realized,  there is no
assurance that these events will occur. The financial  statements do not include
any adjustments to reflect the uncertainties  related to the  recoverability and
classification  of assets or the amounts and  classification of liabilities that
may result from the inability of the Company to continue as a going concern.

Use of Estimates

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of  assets  and  liabilities  at the date of the
financial  statements and the reported  amounts of revenues and expenses  during
the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of
three months or less to be cash equivalents.

Inventory

Inventory  is stated at the lower of cost or  market  and  includes  the cost of
material,  labor and manufacturing overhead. Cost is determined on the first-in,
first-out basis.

Equipment

Depreciation is computed under the straight-line method over the useful lives of
2-10 years.

Prepaid Royalties

Prepaid  royalties  are  amortized  on a  straight-line  basis over an estimated
useful life of 10 years.

1. Summary of Significant Accounting Policies (Continued)

Stock Based Compensation

The Company has adopted the disclosure provision for stock-based compensation of
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation", but continues to account for such items using the intrinsic value
method as outlined under Accounting Principles Board Opinion No. 25, "Accounting
for Stock Issued to Employees".

Revenue Recognition

Revenues from the sale of the Company's  products are  recognized at the time of
shipment. All foreign sales are denominated in U.S. dollars.

Credit Risk

The Company  manufactures  and sells  thermodynamic  devices  principally to the
blood  component  processing  industry and performs  ongoing  evaluations of the
credit  worthiness  of  its  customers.   The  Company  believes  that  adequate
provisions  for  uncollectible  accounts  have  been  made  in the  accompanying
financial statements.

Income Taxes

The liability method is used for accounting for income taxes. Under this method,
deferred tax assets and liabilities are determined based on differences  between
the financial reporting and tax bases of assets and liabilities and are measured
using the enacted tax rates and laws that will be in effect when the differences
are expected to reverse.
The Company used the flow-through method to account for income tax credits.

Net Loss per Share

Net loss per share is computed by dividing the net loss by the weighted  average
number of common  shares  outstanding.  Common stock  equivalents  have not been
included because the effect would be anti-dilutive.

In February 1997, the Financial  Accounting Standards Board issued Statement No.
128, "Earnings per Share" (SFAS 128). SFAS 128 replaced the previously  reported
primary and fully diluted earnings per share with basic and diluted earnings per
share.  Unlike primary earnings per share, basic earnings per share excludes any
dilutive effects of options,  warrants and convertible securities.  SFAS 128 was
adopted  during the year ended June 30,  1998 and had no impact on the basic and
diluted net loss per share for the years ended June 30, 1997 and 1996.

Comprehensive Income

In June 1997,  the FASB  issued  Statement  No.  130,  "Reporting  Comprehensive
Income"  (SFAS 130) which  establishes  standards  for  reporting  disclosure of
comprehensive income and its components (revenues,  expenses,  gains and losses)
in a full  set of  general-purpose  financial  statements.  SFAS  130,  which is
effective  for  fiscal  years  beginning  after  December  15,  1997,   requires
reclassification of financial  statements for earlier periods to be provided for
comparative  purposes.  SFAS 130 was adopted during the year ended June 30, 1999
and did not have a significant impact on the Company's existing disclosures.

1. Summary of Significant Accounting Policies (Continued)

Segment Disclosure

In June 1997, the FASB issued Statement No. 131,  "Disclosure  about Segments of
an Enterprise and Related  Information"  (SFAS 131) which establishes  standards
for the way that public business  enterprises report information about operating
segments.  It also establishes  standards for related disclosures about products
and services,  geographic areas and major customers. SFAS 131 was adopted during
the year  ended  June 30,  1999 and did not  have a  significant  impact  on the
Company's existing disclosures.

Reclassifications

Certain amounts in the prior years financial  statements have been  reclassified
to conform with the 1999 presentation.

2. Inventory

5. Commitments and Contingencies (continued)

Contingencies

The  Company  is  presently  engaged  in various  legal  actions  arising in the
ordinary course of its business.  In the opinion of management,  the Company has
adequate reserves with respect to these matters so that the ultimate  resolution
will not have a material adverse effect on the financial position of the Company
or its results of operations.

6. Shareholders' Equity

Convertible Preferred Stock

In January 1999 the Company completed a private placement of 1,077,540 shares of
Convertible  Preferred Stock ("Preferred  Stock"),  raising  $6,227,342,  net of
commissions  and direct  expenses.  Commissions  of 7% of the gross proceeds and
warrants  to  purchase  200,000  shares of common  stock at $1.70 per share were
issued to the placement agent.  The significant  features of the Preferred Stock
are as follows:

        Voting Rights - The holders of shares of Preferred Stock are entitled to
        voting rights equal to the number of shares of common stock to be issued
        upon  conversion of the  Preferred  Stock.  Additionally,  so long as in
        excess  of  35%  of the  original  amount  of  Preferred  Stock  remains
        outstanding,  the  holders of the  Preferred  Stock  shall be  entitled,
        voting as a separate class,  to elect one director,  who shall be one of
        the authorized number of directors of the Corporation.

        Liquidation  Preferences - In the event of liquidation or dissolution of
        the Company,  the preferred  stockholders  are entitled to priority over
        common  stockholders  with respect to  distribution of Company assets or
        payments to stockholders.  The liquidation  preference is equal to $6.25
        per share compounded annually at 8% per share per year.

        Redemption - When  issued,  the  Preferred  Stock  contained  redemption
        rights  which  allowed the  Preferred  Stock to be  redeemable  upon the
        request of any holder at any time following the fifth  anniversary of
        the date of  issuance.  The  redemption  price shall be the  liquidation
        preference  as stated  above.  However,  on July 30,  1999,  the  common
        stockholders  voted to remove the redemption  rights associated with the
        Preferred Stock.  Removal of the redemption  rights allows the Preferred
        Stock to be included as Stockholders Equity. The excess of the Preferred
        Stock's  redemption  price over its carrying  value is being accreted by
        periodic  charges to accumulated  deficit from the date of issuance thru
        July 30, 1999.

        Conversion  Rights - Holders of the Preferred  Stock have the right to
        convert the preferred stock  ("Beneficial  Conversion  Feature")at the
        option of the holder,  at any time, into shares of common stock of the
        Company at the conversion  rate of one preferred share for five shares
        of common stock.  The  conversion  rate is subject to  adjustment  for
        changes in the Company's  capital structure which would otherwise have
        a dilutive effect on the conversion rate. As of June 30, 1999, 193,540
        shares of Preferred Stock have been converted.

        Beneficial  Conversion  Feature - The value  assigned to the  Beneficial
        Conversion  Feature,  as determined using the quoted market price of the
        Company's  common  stock on the  date  the  Preferred  Stock  was  sold,
        amounted to $3,604,740,  which represents a discount to the value of the
        Preferred Stock.

6. Shareholders' Equity (Continued)

Convertible Preferred Stock (continued)

        Automatic  Conversion  - At the  option of the  Company,  each  share of
        Preferred  Stock may be  converted  into  shares of Common  Stock at the
        conversion rate of 1:5 provided that the shares of the Company's  common
        stock trade at an average  price  equal to or greater  than $5 per share
        for 30 consecutive trading days.

        Dividends - The holders of Preferred  Stock shall be entitled to receive
        dividends  at the  same  rate  and at the  same  time  as any  dividends
        declared on the Company's common stock.

In addition,  preferred shares are subject to certain transfer  restrictions and
are entitled to certain registration rights.

Common Stock

The Company  completed  a private  financing  on  December  31, 1997 in which it
received  $6,432,919  net of  expenses.  The  proceeds  from the  offering  were
received  from the sale of  2,786,714  shares of common stock at $2.50 per share
and issued  three year  warrants  to the  purchasers  representing  the right to
acquire an additional  278,100 shares in the aggregate,  at an exercise price of
$3.00 per share. No warrants have been exercised as of June 30, 1999.

The Company  completed a minimum equity offering of units in a private placement
on November  27,  1996,  in which it received  proceeds  of  $7,274,500,  net of
expenses.  The  proceeds  from  the  offering  were  received  from  the sale of
1,378,001  units at $6.00 per unit.  Each unit consisted of two shares of common
stock and a seven year warrant  representing the right to acquire one additional
share of common stock at an exercise price of $3.885 per share. No warrants have
been exercised as of June 30,1999.

On July 30, 1996, the Company entered into an agreement with a vendor to produce
up to $2,500,000 of product for the Company.  Under the terms of the  agreement,
the vendor  can elect to  receive  payment  in  restricted  common  stock of the
Company at a 25%  discount  from the market  price on the date the  election  to
receive stock is made.  During fiscal 1997, the Company issued 145,586 shares of
common stock for this product,  and recorded these transactions at the estimated
fair value of  $444,297  on the date of the  transaction  and  recorded  the 25%
discount from market price as operating expense. The Company is not obligated to

shares of common stock. The warrants expire in December 2000.

In  conjunction  with the  placement  of Series C Preferred  stock in 1993,  the
placement  agent,  Paradise  Valley  Securities,  received  warrants to purchase
shares of the  Company's  common stock at $1.20 per share.  There were 5,625 and
37,500 warrants converted in fiscal 1998 and 1997, respectively.

Stock Options

On July 31,  1996 and May 29,  1996,  the  Company  issued  options to  purchase
200,000 and 100,000  shares,  respectively,  of the  Company's  common stock for
consulting  services.  The  exercise  price is equal to the fair market value as
determined by the closing bid price for the  Company's  common stock on the date
of grant. The Company has recorded stock  compensation  expense  recognizing the
estimated  fair value of the  options of  $56,000,  $64,000  and $56,000 for the
years ended June 30, 1999, 1998 and 1997, respectively.

The Company has issued  options to purchase  shares of common stock  pursuant to
its  Amended  1994 Stock  Option  Plan  (1994  Plan),  under  which a maximum of
1,450,000 options may be granted.  Options are granted at prices which are equal
to 100% of the fair  market  value on the date of grant,  and expire over a term
not to exceed  ten  years.  Options  generally  vest  ratable  over a three year
period.  During fiscal 1998, the  Stockholders of the Company  approved the 1998
Employee Equity Incentive Plan ("1998 Plan") with 798,000 shares underlying that
plan.

The Company has also issued options to directors,  employees and  consultants as
compensation for services. These options vest and are exercisable over a variety
of periods as determined by the Company's Board of Directors.

SFAS 123 requires  the use of option  valuation  models to provide  supplemental
information regarding options granted after June 30, 1995. Pro forma information
regarding  net loss and net loss per share shown below was  determined as if the
Company had accounted for its employee stock options under the fair value method
of that statement.

The Black-Scholes option valuation model was developed for use in estimating the
fair  value of  traded  options.  The  Company's  employee  stock  options  have
characteristics  significantly  different  from those of traded  options such as
vesting  restrictions and extremely limited  transferability.  In addition,  the
assumptions used in option  valuation models (see below) are highly  subjective,
particularly  the  expected  stock price  volatility  of the  underlying  stock.
Because changes in these subjective input  assumptions can materially affect the
fair value estimate, in management's opinion, the existing models do not provide
a reliable single measure of the fair value of its employee stock options.

For purposes of pro forma  disclosures,  the estimated fair value of the options
is amortized over the options' vesting periods. The pro forma effect on net loss
for fiscal 1997  through 1999 is not  representative  of the pro forma effect on
operations in future years because it does not take into consideration pro forma
compensation expense related to grants made prior to July 1, 1995. The Company's
pro forma information is as follows for the years ended June 30:

  Net Loss                       1999               1998               1997
                                 ----               ----               ----
 As reported                  ($6,098,904)       ($9,550,795)       ($4,805,822)
 Pro Forma                     (6,594,368)       (10,217,657)        (5,325,270)
 Net loss per share
 As reported                       ($0.50)            ($0.54)            ($0.32)

The fair value of each option  grant is estimated on the date of grant using the
Black-Scholes   option-pricing   model  with  the  following   weighted  average
assumptions:  expected  volatility  of  92%;  an  expected  life of 3  years;  a
risk-free interest rate of 5.62% and no expected dividends. The weighted average
grant date fair value of options  granted  during the years ended June 30, 1999,
1998 and 1997 was $1.70, $1.69 and $1.80, respectively.

7. Major Customers and Foreign Sales

During the fiscal year ended June 30, 1999,  sales from a  significant  customer

net  sales.  During the  fiscal  year  ended  June 30,  1998 there was no single
customer which  represented 10% of net sales;  foreign sales were  approximately
50% of net  sales.  During the fiscal  year  ended June 30,  1997,  sales from a
significant  customer  totaled  $4,044,489 or 61% of net sales and foreign sales
were 15% of net sales.

At June 30, 1999, the Company had net operating loss  carryforwards  for federal
and state  income tax  purposes  of  approximately  $25,585,000  and  $7,500,000
respectively,  that are available to offset future income. The federal and state
loss  carryforwards  expire in various years between 2002 and 2019, and 2000 and
2004, respectively.

At  June  30,  1999,  the  Company  has  research  and  experimentation   credit
carryforwards of approximately  $293,000 for federal tax purposes that expire in
various  years  between 2002 and 2019 and $174,000 for state income tax purposes
that do not have an expiration date. In addition,  the Company has approximately
$15,000 in other state tax credits.

Significant  components of the Company's deferred tax assets and liabilities for
federal and state income taxes are as follows:

Because of the "change of ownership" provisions of the Tax Reform Act of 1986, a
portion of the Company's federal net operating loss and credit carryovers is
subject to an annual  limitation  regarding  their  utilization  against taxable
income in future periods.

          FIFTH: The Corporation is to have perpetual existence.

          SIXTH:  Whenever a compromise or arrangement is proposed  between this

     Corporation  and its  stockholders  or any  class  of  them,  any  court of
     equitable jurisdiction within the State of Delaware may, on the application
     in a summary way of this  Corporation  or of any  creditor  or  stockholder

     (3/4) in value of the  creditors  or  class  of  creditors,  and/or  of the
     stockholders or class of stockholders of this Corporation,  as the case may

     this Corporation as consequence of such compromise or arrangement, the said
     compromise or arrangement and the said reorganization  shall, if sanctioned
     by the court to which the said application has been made, be binding on all
     the  creditors or class of  creditors,  and/or on all the  stockholders  or
     class of stockholders, of this Corporation, as the case may be, and also on
     this Corporation.

          SEVENTH: For the management of the business and for the conduct of the
     affairs of the  Corporation,  and in  further  definition,  limitation  and
     regulation of the powers of the Corporation and of its directors and of its
     stockholder  or any  class  thereof,  as the  case  may be,  it is  further
     provided:

          1. The  management  of the  business and the conduct of the affairs of
     the  Corporation  shall be vested in its Board of Directors.  The number of
     directors which shall constitute the entire Board of Directors

<PAGE>



     shall  be fixed by, or in the manner  provided  in, the  Bylaws,  which
     number  has been set  initially  at not less than three nor more than nine,
     with the specific  number set by the Board of Directors  from time to time,
     and provided  further that the number of directors  constituting the entire
     Board shall be six until  otherwise fixed by a majority of the entire Board
     of Directors.  The phrase "entire Board of Directors" and the phrase "total
     number of directors" shall be deemed to have the same meaning,  to wit, the
     total number of directors which the Corporation would have if there were no
     vacancies. No election of directors need be by written ballot.

          2. After the  original or other  Bylaws of the  Corporation  have been
     adopted,  amended, or repealed,  as the case may be, in accordance with the
     provisions  of Section 109 of the General  Corporation  Law of the State of
     Delaware and, after the Corporation has received any payment for any of its
     stock,  the power to adopt,  amend, or repeal the Bylaws of the Corporation
     may be exercised by the Board of  Directors of the  Corporation;  provided,
     however,  that any  provision  for the  classification  of directors of the
     Corporation  for staggered  terms  pursuant to the provisions of subsection
     (d) of section 141of the General  Corporation  Law of the State of Delaware
     shall be set  forth in the  initial  Bylaws  or in  Bylaws  adopted  by the
     stockholders entitled to vote of the Corporation unless provisions for such
     classification shall be set forth in this certificate of incorporation.

          3.  Whenever the  Corporation  shall be  authorized  to issue only one
     class of stock,  each outstanding share shall entitle the holder thereof to
     notice of, and the right to vote at, any meeting of stockholders.  Whenever
     the Corporation  shall be authorized to issue more than one class of stock,
     no  outstanding  share of any class of stock which is denied  voting  power
     under the provisions of this Certificate of Incorporation shall entitle the
     holder thereof to the right to vote at any meeting of  stockholders  except
     as the  provisions  of  paragraph  (b)(2)  of  Section  242 of the  General
     Corporation Law of the State of Delaware shall otherwise require; provided,
     that no share of any such class  which is  otherwise  denied  voting  power
     shall  entitle the holder  thereof to vote upon the increase or decrease in
     the number of authorized shares of said class.

          EIGHTH:  The personal liability of the directors of the Corporation is
     hereby  eliminated to the fullest  extent  permitted by  subsection  (7) of
     subsection 9b) of Section 102 of the General  Corporation  Law of the State
     of Delaware, as the same may be amended and supplemented.

          NINTH:  The  Corporation  shall,  to the fullest  extent  permitted by
     Section 145 of the General Corporation Law of the State of Delaware, as the
     same may be amended and supplemented, indemnify any and all persons whom it
     shall have power to  indemnify  under said section from and against any and
     all of the expenses, liabilities or other matters referred to in or covered
     by said section,  and the indemnification  provided for herein shall not be
     deemed  exclusive  of any other  rights to which those  indemnified  may be
     entitled under any Bylaw, agreement,  vote of stockholders or disinterested
     directors or otherwise,  both as to action in his official  capacity and as
     to action in another capacity while holding such office, and shall continue

<PAGE>



      as to a person who has ceased to be a director,  officer,  employee or
     agent  and  shall  inure  to  the  benefit  of  the  heirs,  executors  and
     administrators of such a person.

          TENTH: SERIES A CONVERTIBLE PREFERRED STOCK

          Section 1. Designation and Amount.

          The shares of such series shall be  designated as Series A Convertible

     shall be 1,200,000.

          Section 2. Dividend Rights.

          The holders of shares of Series A Convertible Preferred Stock shall be
     entitled  to  receive  out of any  funds  legally  available  noncumulative

     Directors;  provided  that,  for the purposes of this  Section 2 only,  the
     holders of the Series A Convertible  Preferred Stock shall be deemed to own
     the number of shares of Common  Stock  into  which such  shares of Series A
     Convertible  Preferred  Stock are  convertible at the time such dividend is
     declared.

        Section 3.    Voting Rights.

     director by the affirmative vote of the holders of a majority of the Series

     shareholders  duly called for that  purpose,  or by written  consent of the

     Convertible Preferred Stock given at a special meeting of such shareholders
     duly  called  for that  purpose,  or by written  consent of the  holders of
     record of a  majority  of the Series A  Convertible  Preferred  Stock.  Any
     vacancy  created  thereby  may  be  filled  by  the  holders  of  Series  A
     Convertible  Preferred  Stock  represented  at such  meeting  or by written
     consent  by holders of a  majority  of the Series A  Convertible  Preferred
     Stock.

          (c) Series A  Convertible  Preferred  Stock - Special  Voting  Rights.
     Provided that at least 35% of the Aggregate Original Amount of the Series A

     Preferred Stock from time to time outstanding:

               (i) take any action that would  result in (A) a sale,  conveyance
          or other  disposition or distribution of all or  substantially  all of
          the assets of the Corporation or (B) merger, consolidation, or similar
          transaction with any other corporation or entity where the Corporation
          is not the survivor.

               (ii)  declare any  dividends  or any other  distributions  on, or
          redeem or repurchase any, Equity  Securities (as defined in Section 8)

          redemptions  or  repurchases  required  by the terms of the  governing
          instrument for the related equity  securities which have been approved
          by the holders of the Series A Convertible Preferred Stock pursuant to
          Section 3(c)(iii) below);

               (iii) issue or authorize  the issuance of any shares of Preferred
          Stock or any warrant,  right,  option,  convertible  security or other

          rights  which are  senior to or on a parity  with the  preferences  or

               (iv) amend the  Corporation's  Certificate  of  Incorporation  or
          Bylaws; or

               (v)  make  or hold  any  direct  or  indirect  investment  in any
          corporation,  investment  in the  debt  or  equity  securities  of any

     Section 4. Liquidation Preference.

          In the event of any voluntary or involuntary liquidation,  dissolution
     or  winding  up of the  affairs  of  the  Corporation  (any  such  event  a
     "Liquidation  Event")  then,  and in that  event,  the  holders of Series A
     Convertible  Preferred  Stock shall be entitled to receive  with respect to
     any such  Liquidation  Event prior and in preference to any distribution of
     any of the assets of the  Corporation  to the holders of Common Stock or to
     the  holders  of any  other  series of  preferred  stock by reason of their
     ownership  thereof,  an amount in cash or equivalent value in securities or
     other  consideration  equal to the "liquidation  preference" herein. If the
     amount of such  distribution  is insufficient to permit full payment of the
     "liquidation   preference"   herein,   then  such  distribution   shall  be
     distributed  ratably to the holders of the Series A  Convertible  Preferred
     Stock  on the  basis of the  number  of  shares  of  Series  A  Convertible
     Preferred Stock held. After payment in full of the "liquidation preference"
     owed to the  holders  of the  Series A  Convertible  Preferred  Stock,  the
     holders of the Common  Stock shall be  entitled,  to the  exclusion  of the
     holders  of the  Series  A  Convertible  Preferred  Stock,  to share in all
     remaining  assets of the  Corporation in accordance  with their  respective
     interests.

          For the  purposes  this Section 4, the term  "liquidation  preference"
     shall mean,  with respect to the Series A Convertible  Preferred  Stock, an
     amount equal to $6.25 per share (the Basic Preference  Amount") which Basic
     Preference  Amount  shall  increase at the rate of eight  percent  (8%) per
     share per year,  compounded annually on each subsequent  anniversary of the
     Series A Original  Issue Date (in the event of a Liquidation  Event between
     any such anniversaries,  the Basic Preference Amount increase for such year
     shall be prorated accordingly);

          Section 5. Conversion Rights.

          (a) Right to Convert Series A Convertible  Preferred Stock. Each share
     of Series A Convertible  Preferred Stock shall be convertible,  without the
     payment  of any  additional  consideration  and at the option of the holder
     thereof,  at any time after the Series A Original  Issue Date at the office
     of the  Corporation  (or any  transfer  agent for the Series A  Convertible
     Preferred Stock) into shares of Common Stock at the then effective Series A
     Conversion  Rate (as defined in Section  5(c) hereof) and adjusted on a per
     share basis giving effect to any adjustments required by Section 5 hereof.

          (b) Automatic Conversion. Each share of Series A Convertible Preferred
     Stock may, at the option of the  Corporation,  be converted  into shares of
     Common Stock at the then effective  Series A Conversion Rate (as defined in
     Section 5(c) hereof) and adjusted on a per share basis giving effect to any
     adjustments  required by Section 5 hereof  provided  that the shares of the
     Corporation's  Common  Stock trade at an Average  Price equal to or greater
     than $5.00 per share  (subject to any  adjustments  for events set forth in
     Section 5(e) through (i)) for 30 consecutive  trading days. The Corporation
     shall  give at least 20 days  prior  written  notice to the  holders of the
     Series  A  Convertible  Preferred  Stock  as to  any  automatic  conversion
     pursuant to this Section 5(b),  such  conversion  being  effective no later
     than the twenty (20) days following


<PAGE>



      receipt by the holders of the Series   A Convertible  Preferred Stock of
     such notice; provided,  however, that nothing shall prohibit holders of the
     Series A Convertible Preferred Stock at any time, including after such time
     as the  Corporation  has given notice under this Section  5(b),  to convert
     their  Series A  Convertible  Preferred  Stock into shares of Common  Stock
     pursuant to Section 5(a).

          (c) Series A Conversion Rate.  Subject to the adjustments  provided in
     subsections  (e)  through  (i) of this  Section  5, each  share of Series A
     Convertible  Preferred  Stock shall be convertible  into five (5) shares of
     Common Stock

          (d) Mechanics of Conversion. Before any holder of Series A Convertible
     Preferred  Stock  shall be entitled to convert the same into full shares of
     Common Stock  pursuant to Section 5(a) hereof,  the holder shall  surrender
     the certificate or certificates  therefor,  duly endorsed, at the office of
     the  Corporation  or of any  transfer  agent for the  Series A  Convertible
     Preferred  Stock and shall give written  notice to the  Corporation at such
     office that such holder  elects to convert the same and shall state therein
     such  holder's  name or the  name or names of the  nominees  in which  such
     holder wishes the certificate or certificates for shares of Common Stock to
     be issued. The Corporation shall, as soon as practicable  thereafter but in
     no event later than four (4) business days after the  Corporation  receives
     all documents,  including notice and certificates,  necessary to effect the
     conversion  or, with respect to conversion  pursuant to Section 5(b) on the
     date specified in the notice (unless converted earlier),  issue and deliver
     at the address of such holder on the books and records of the  Corporation,
     or to such holder's nominee or nominees,  a certificate or certificates for
     the number of shares of Common Stock to which such holder shall be entitled
     as aforesaid,  together with cash in lieu of any fractional shares.  Except
     as otherwise  set forth in Section  5(b) above,  such  conversion  shall be
     deemed to occur  immediately  prior to the close of business on the date of
     surrender  of the  shares of  Series A  Convertible  Preferred  Stock to be
     converted,  and the person or  persons  entitled  to receive  the shares of
     Common Stock issuable upon conversion  shall be treated for all purposes as
     the record holder or holders of such shares of Common Stock on such date.

          Notwithstanding  anything to the  contrary  contained  herein,  if any
     holder of Series A  Convertible  Preferred  Stock  elects to  convert  such
     holder's  shares  at any  time  prior  to the  record  date  for any  vote,
     dividend,  redemption,  liquidation,  dissolution  or winding  up, or other
     actions for which a record date is set and the holder receives prior notice
     pursuant to Section 6, or prior to the effective date of any such event for
     which either no record date is set or respecting  which notice  pursuant to
     Section 6 is not received,  then for all purposes such conversion  shall be
     treated as having  occurred  prior to such date or  effective  date and the
     holder  shall be treated  as the owner of the Common  Stock into which such
     Series A Convertible Preferred Stock is convertible for all purposes.

          (e) Adjustments for Subdivisions and Combinations.  If the Corporation
     shall at any time,  or from time to time after the Series A Original  Issue
     Date,  effect a subdivision of the outstanding  Common Stock,  the Series A
     Conversion Rate then in effect immediately before


<PAGE>

      such subdivision shall be   proportionately  increased,  and conversely,
     if the Corporation  shall at any time or from time to time after the Series
     A Original Issue Date combine the outstanding  shares of Common Stock,  the
     Series A Conversion Rate then in effect immediately before such combination
     shall be proportionately  decreased. Any adjustment under this Section 5(e)
     shall  become  effective  at  the  close  of  business  on  the  date  such
     subdivision or combination becomes effective.

          (f) Adjustments for Certain Dividends and Distributions.  In the event
     the  Corporation  at any  time,  or from time to time  after  the  Series A
     Original  Issue  Date,  shall  make or issue  or fix a record  date for the
     determination  of holders of Common Stock entitled to receive a dividend or
     other  distribution  payable in additional shares of Common Stock, then and
     in each such event the  Series A  Conversion  Rate then in effect  shall be
     increased  as of the time of such  issuance  or, in the event such a record
     date shall have been  fixed,  as of the close of  business  on such  record
     date,  by  multiplying  the  Series A  Conversion  Rate then in effect by a
     fraction:

               (i) the numerator of which shall be the total number of shares of
          Common Stock issued and outstanding  immediately  prior to the time of
          such  issuance  or the close of  business on such record date plus the
          number of shares of Common Stock  issuable in payment of such dividend
          or distribution; and

               (ii) the denominator of which shall be the total number of shares
          of Common Stock issued and outstanding  immediately  prior to the time
          of such  issuance  or the  close  of  business  on such  record  date;
          provided,  however, if such record date shall have been fixed and such
          dividend is not fully paid or if such  distribution  is not fully made
          on the date  fixed  therefor,  the Series A  Conversion  Rate shall be
          recomputed accordingly as of the close of business on such record date
          and thereafter the Series A Conversion Rate shall be adjusted pursuant
          to  this  Section  5(f)  as of the  time  of  actual  payment  of such
          dividends or distributions.

          (g) Adjustment for Other Dividends and Distributions. In the event the
     Corporation  at any time,  or from time to time after the Series A Original
     Issue Date shall make or issue, or fix a record date for the  determination
     of  holders of Common  Stock  entitled  to  receive,  a  dividend  or other
     distribution  payable in securities of the Corporation other than shares of
     Common Stock (but including securities convertible into Common Stock), then
     and in each such  event  provisions  shall be made so that the  holders  of
     Series A Convertible Preferred Stock shall receive upon conversion thereof,
     in addition to the number of shares of Common Stock  receivable  thereupon,
     the amount and type of securities of the  Corporation  that they would have
     received  on a per share  basis had their  Series A  Convertible  Preferred
     Stock been  converted  into Common  Stock on the date of such event and had
     such holders  thereafter,  during the period from the date of such event to
     and including the conversion date,  retained such securities  receivable by
     them as aforesaid during such period giving  application to all adjustments
     called for during  such  period  under this  Section 5 with  respect to the
     rights of the holders of the Series A Convertible Preferred Stock.


<PAGE>



          (h) Adjustments for Reclassification, Exchange or Substitution. If the
     Common  Stock  issuable  upon the  conversion  of the Series A  Convertible
     Preferred  Stock shall be changed  into the same or a  different  number of
     shares of any class or  classes  of stock of the  Corporation,  whether  by
     capital  reorganization,  reclassification  or  otherwise  (other than by a
     subdivision, a combination or a stock dividend as provided for elsewhere in
     this  Section 5), then and in each event the holder of each share of Series
     A Convertible  Preferred  Stock shall have the right  thereafter to convert
     such share into the kind and amount of shares of stock or other  securities
     and property receivable upon such reorganization, reclassification or other
     change by the  holders of the  number of shares of Common  Stock into which
     each such share of Series A  Convertible  Preferred  Stock  might have been
     converted  immediately prior to such  reorganization,  reclassification  or
     other change,  all subject to further  adjustment as provided  elsewhere in
     this Section 5.

               (i) Sale of Shares  Below  Dilution  Price.  For purposes of this
          Section  5(i),  the  Dilution  Price shall be  initially  equal to one
          dollar and twenty-five cents ($1.25)..

                    (a) If at any time after the Series A Original  Issue  Date,
               the  Corporation  shall  issue  for cash or  other  consideration
               shares  of  Common  Stock  or any  security  convertible  into or
               exchangeable or exercisable for shares of Common Stock at a price
               per share of Common Stock  calculated  by including the aggregate
               proceeds  per  share to the  Corporation  upon  issuance  and any
               additional  consideration  per share  payable to the  Corporation
               upon any such  conversion,  exchange  or  exercise  (in each case
               before  deduction of any per share discounts,  commissions,  fees
               and other  expenses of issuance and  marketing),  (the "New Issue
               Price),  that is less than the Dilution Price then in effect, the
               Dilution  Price shall be  automatically  adjusted down to the new
               Issue Price and the  aggregate  number of shares of Common  Stock
               issuable upon the  conversion of each share of Series A Preferred
               Stock  shall  be  automatically  adjusted  to  equal  the  result
               obtained by dividing the initial Purchase Price of $6.25 for each
               share of Series A Preferred  Stock by the New Issue Price. In the
               event that this  Section  5(i)  applies,  the Series A Conversion
               Rate shall determined by this Section 5(i)(a).

                    For example,  assume that (i) the Series A  Conversion  Rate
               was five (5) shares of Common  Stock for each share of  Preferred
               Stock;  (ii) the initial  Purchase Price was $6.25 per share, and
               (iii) the Purchaser had acquired 100 shares of Series A Preferred
               Stock for an  aggregate  purchase  price of  $625.00.  If the New
               Issue Price is $.50 per share,  the new  Dilution  Price would be
               $.50 per share and each share of Series A  Preferred  Stock would
               be convertible into 12.5 shares of Common Stock.

                    (b) For the purpose of this  Section  5(i),  the issuance by
               the Corporation of securities convertible into or exchangeable or
               exercisable  for  Common  Stock  shall be deemed to  involve  the
               immediate  issuance  of the  maximum  number  of shares of Common
               Stock issuable upon the conversion,  exchange or exercise of such
               securities  for a  consideration  equal to the minimum  aggregate
               consideration receivable by the Corporation upon such conversion,
               exchange or exercise.  In the event that securities are issued by
               the Corporation that result in an adjustment to

<PAGE>



                the Series A Conversion  Rate  pursuant to this Section 5(i)
               and such  securities  are not  converted,  exchanged or exercised
               prior  to the  expiration  of the  right of the  holders  of such
               securities to effect any such action,  then immediately upon such
               expiration  of the right of the  holders  of such  securities  to
               effect any such action, the Series A Conversion Rate and Dilution
               Price shall be  recomputed  (but such  redetermination  shall not
               affect  the  Series A  Conversion  Rate of any shares of Series A
               Preferred   Stock  that  have  been   converted   prior  to  such
               expiration)  and effective  immediately  upon such expiration the
               Dilution Price and Series A Conversion Rate shall be increased to
               the ratio  which it would  have been  (but  reflecting  and other
               adjustments  in the Series A  Conversion  Rate made  pursuant  to
               other  provisions  of this  Section 5 after the  issuance of such
               securities) had such  adjustments to the Series A Conversion Rate
               and Dilution Price not been made.

                    (j) Issue Taxes. The Corporation shall pay any and all issue
               and other  taxes  that  maybe  payable in respect of any issue or
               delivery  of shares of Common  Stock on  conversion  of shares of
               Series A Convertible Preferred Stock,  excluding any tax or other
               charge  imposed in connection  with any transfer  involved in the
               issue and delivery of shares of Common Stock in a name other than
               that in which the shares of Series A Convertible  Preferred Stock
               so converted were registered,  which tax or charge shall be borne
               by the transferor.

                    (k) Reservation of Stock. The Corporation shall at all times
               reserve and keep  available  out of its  authorized  but unissued
               shares of Common Stock  solely for the purpose of  effecting  the
               conversion  of the shares of the Series A  Convertible  Preferred
               Stock one and  one-half  times the number of its shares of Common
               Stock as shall  from time to time be  sufficient  to  effect  any
               conversion  of any or all  outstanding  shares  of the  Series  A
               Convertible  Preferred  Stock.  If at  any  time  the  number  of
               authorized  but  unissued  shares  of Common  Stock  shall not be
               sufficient  to  effect  the  conversion  of all then  outstanding
               shares  of  the  Series  A  Convertible   Preferred   Stock,  the
               Corporation  shall  take such  corporate  action  as may,  in the
               opinion of its counsel,  be necessary to increase its  authorized
               but  unissued  shares of Common Stock to such number of shares as
               shall be sufficient for such purpose.

                    (l) Fractional  Shares.  No fractional share shall be issued
               upon  the   conversion  of  any  share  or  shares  of  Series  A
               Convertible   Preferred   Stock.   All  shares  of  Common  Stock
               (including  fractions)  issuable upon conversion of more than one
               share of Series A Convertible Preferred Stock by a holder of such
               stock shall be aggregated for purposes of determining whether the
               conversion would result in the issuance of any fractional  share,
               if,  after  aggregation,  the  conversion  would  result  in  the
               issuance of a fractional  share of Common Stock,  the Corporation
               shall,  in lieu of issuing any fractional  share,  pay the holder
               otherwise  entitled  to such  fraction a sum in cash equal to the
               fair market value of such fraction on the date of conversion  (as
               determined in good faith by the Board of Directors).

                    (m) Successive Changes. The above provisions of this Section
               5 shall similarly apply to successive combinations, subdivisions,
               dividends and  distributions  on or of the Common Stock after the
               Series A Original Issue Date.

                    (n)  Subsequent Events. On the Series A Original Issue Date,
                         and  thereafter,  from  time to time,  within  ten (10)
                         Business  Days of the  occurrence  of any  event  which
                         would  have  the  result  of  changing   the  Series  A
                         Conversion  Rate,  the  Corporation  shall  notify  the
                         holders of the Series A Convertible  Preferred Stock of
                         the  nature of such  event and of the newly  calculated
                         figures  resulting from such change and the calculation
                         in reasonable detail.

     Section 6. Notices of Record Date.

          In the event of (i) any taking by the  Corporation  of a record of the
     holders of any class or series of securities for the purpose of determining
     the  holders  thereof who are  entitled  to receive  any  dividend or other
     distribution  or  (ii)  any  reclassification  or  recapitalization  of the
     capital  stock  of  the   Corporation   or  any  voluntary  or  involuntary
     dissolution,  liquidation or winding up of the affairs of the  Corporation,
     the  Corporation  shall send by (1) personal  delivery to such holder,  (2)
     first class mail addressed, postage prepaid, and addressed to the holder at
     the address appearing on the books of the Corporation,  or (3) facsimile to
     such  holder  at the  facsimile  number  provided  by  such  holder  to the
     Secretary  of the  Corporation,  at least ten (10) days prior to the record
     date specified  therein, a notice specifying (A) the date on which any such
     record  is  to  be  taken  for  the  purpose  of  such  dividend  or  other
     distribution  and a description of such dividend or  distribution,  (B) the
     date on  which  any  such  reorganization,  reclassification,  dissolution,
     liquidation  or winding up is  expected  to become  effective,  and (C) the
     time,  if any is to be fixed,  as to when the holders of record of Series A
     Convertible  Preferred  Stock shall be entitled to exchange  their Series A
     Convertible  Preferred  Stock for securities or other property  deliverable
     upon such  reorganization,  reclassification,  dissolution,  liquidation or
     winding up. For purposes of this notice  provision,  notice shall be deemed
     to have been  given  (1) the next day in the case of  notice by a  national
     courier  service,  or  (2) in the  case  of  facsimile,  upon  sending  the
     facsimile.

        Section 7. Reacquired Shares.

          Any  shares  of  Series  A  Convertible   Preferred  Stock  converted,
     purchased or otherwise acquired by the Corporation in any manner whatsoever
     shall be retired and cancelled promptly after the acquisition thereof, and,
     if necessary to provide for the lawful purchase of such shares, the capital
     represented by such shares shall be reduced in accordance  with the General
     Corporation Law of the State of Delaware.  All such shares shall upon their
     cancellation  become  authorized  but unissued  shares of Preferred  Stock,
     $.001 par value,  of the Corporation and may be reissued as part of another
     series of Preferred Stock, $.001 par value, of the Corporation.

other forms of protection thereof, shall be and remain the property of Employer.

may be  requested  by Employer  to enable  Employer to protect its rights to any
such Developments. If Employer requires Employee's assistance under this section

to contract, then the latter shall prevail; but in such event, the provisions of

                    any calendar quarter and provided that ASAHI gives THERMO at
                    least thirty (30) days  advance  notice of the need for such
                    time  and  provides   THERMO  with  a  report  of  the  work
                    assistance  needed.  Thereafter,  during  the  term  of this
                    Agreement,  in  order  to  reasonably  assist  ASAHI  in its
                    efforts to  manufacture or have  manufactured  the Auto-Cryo
                    Kit (with the  exception of the  Applicators),  THERMO shall
                    provide technical  assistance as the parties may agree. When
                    THERMO  personnel are in Japan at the request of ASAHI,  the
                    living and travel expenses from the U.S. to Japan,  and back
                    to the U.S.,  will be paid by THERMO  during the  initial 12
                    month period. After the initial 12 month period, THERMO will

                    make available technical and support  assistance, as may be
                    requested by ASAHI and agreed to by  THERMO  pursuant  to
                    THERMO's  then standard rates  and charges, including travel
                    and accommodation.

               e.   Clinical  Data,  Test  Material and  Advertising  Materials.
                    THERMO shall provide to ASAHI sales, marketing and technical
                    assistance  and  Auto-Cryo  Kit,   Device  and   Applicators
                    training and support that THERMO deems appropriate to enable
                    ASAHI  to  localize,  as  defined  in  the  Agreement,   the
                    Auto-Cryo Kit, Device and Applicators, and for ASAHI to sell
                    and provide Auto-Cryo Kit maintenance.  THERMO shall provide
                    ASAHI  with  a  reasonable   amount  of  sales   literature,
                    advertising materials and point of purchase (i.e., Auto-Cryo
                    Kit display) materials in English, as prepared by THERMO and
                    as may  be  necessary  or  appropriate  to  allow  ASAHI  to
                    complete  Localization  and promote and enhance the sales of
                    Auto-Cryo  Kit,  Device and  Applicators.  THERMO shall also
                    provide  to ASAHI,  when and as  available,  all test  data,
                    clinical trial studies  (including,  but not limited to, all
                    information  exchanged with FDA, within two weeks of receipt
                    from  FDA or  submission  to FDA)  and  related  information
                    available  to THERMO in order to assist  ASAHI in  obtaining
                    governmental approvals for the System.

B-3  The  following  new  section  shall  be  added  to the  Paragraph  2 of the
Agreement:

               h.   Manufacturing  Information.  THERMO shall, within sixty (60)
                    days following  execution of this  Amendment,  enter into an
                    arrangement  with Tashiro  Patent  Office in Japan to hold a
                    certified   duplicate   copy  of  all  technical  and  other
                    information  relating to the  manufacture  of the Device and
                    Applicators, including specifications,  drawings and quality
                    control information ("Technical Documentation"), which shall
                    in turn be delivered by the Tashiro  Patent  Office to ASAHI
                    upon the occurrence of events stated in Section 15.f of this
                    Amendment,  as  certified  by  the  parties.  The  Technical
                    Documentation  shall  be  updated  by  additional  certified
                    copies  of  current  information  by THERMO  annually  on or
                    before  August  30 of each  year.  ASAHI  shall  pay for all
                    storage and holding  fees charged by Tashiro  Patent  Office
                    for holding the Technical Documentation.  In addition to the
                    foregoing,  and following the  occurrence of an event stated
                    in Section  15.f,  THERMO  shall  from time to time,  and as
                    resources  are  available,   make  available  to  ASAHI  the
                    services  of  such  personnel  of  THERMO  as  THERMO  deems
                    necessary  in  order  to  assist  ASAHI  in its  efforts  to
                    manufacture or have manufactured the Device and Applicators.
                    THERMO will make available technical and support assistance,
                    as may  be  requested  by  ASAHI  and  agreed  to by  THERMO
                    pursuant  to  THERMO's  then  standard  rates  and  charges,
                    including travel and accommodation.

        i.     FDA Approval
               i)     THERMO  shall make its best efforts to obtain FDA approval
                      to market  the  System  containing  ATAK and shall  submit
                      periodic  reports to show the status and  progress  of the
                      development of ATAK to ASAHI at least once


<PAGE>4



                      every  calendar  quarter,  beginning  with the first  full
                      calendar quarter following execution of this Amendment.
               ii)    THERMO  shall submit to FDA an  application  to market the
                      System   containing   ATAK  promptly  upon  completion  of
                      clinical   trials  and  review  of  trial   outcomes   and
                      preparation  of  submission,  but in no event  later  than
                      three  (3)  years  after  the   Effective   Date  of  this
                      Amendment.

               j.   Clinical Trial(s) and Governmental  Approval in Japan. ASAHI
                    shall have sole  responsibility  for  diligently  conducting
                    preclinical and clinical  trial(s) and shall diligently make
                    all regulatory submissions necessary for the approval of the
                    right to market  and to  receive  the  reimbursement  of the
                    System in Japan and THERMO  shall  cooperate  with ASAHI for
                    such trial(s) and  regulatory  submissions  upon  reasonable
                    requests  by ASAHI.  ASAHI  shall  purchase  the Devices and
                    Auto-Cryo  Kit from  THERMO  for  preclinical  and  clinical
                    trial(s)  in Japan  at  pricing  as  shown  in the  attached
                    confidential   Exhibit  D  and  THERMO  shall  provide  such
                    materials  upon  ASAHI's  request  for  shipment to ASAHI as
                    scheduled  by THERMO.  In addition to the  foregoing,  ASAHI
                    shall  cooperate  with THERMO in  establishing  pre-clinical
                    protocol for assay of thrombin components extracted with the
                    ATAK,  and  shall  submit to THERMO  the  pre-clinical  data
                    collected by ASAHI.  THERMO shall pay incremental  costs for
                    such data and  formatting  of such data as  outlined  in the
                    confidential attached Exhibit D.

C-1     Section 3.a. of the Agreement shall be modified to read as follows:

               a.   License  and  Distribution  Fee.  ASAHI  previously  paid  a
                    non-refundable manufacturing and distribution license fee to
                    THERMO of net  $400,000  US by wire  transfer as provided in
                    Section 3.a of the Agreement. By this Amendment, ASAHI shall
                    pay  THERMO an  additional  manufacturing  and  distribution
                    license  fee of a lump sum  payment  of gross **  [Redacted:
                    Removed  for  confidential  treatment  pursuant  to SEC Rule
                    24b-2 under  separate  filing] ** for the rights  granted to
                    ASAHI by THERMO set forth in Section B-1 of this  Amendment.
                    The  license  fee  shall be paid by ASAHI  and  received  by
                    THERMO  no  later  than  June  30,  1999,  by wire  transfer
                    separate  from the wire  transfer  for the  purchase  of the
                    common shares defined below.

C-2 The following paragraph shall be added to Paragraph 3 of the Agreement.

               J.   Shares.  ASAHI shall  purchase  common shares  ("Shares") of
                    THERMO  equivalent to  US$700,000,  the aggregate  number of
                    shares to be based upon the closing price of THERMO's  stock
                    on June 23, 1999.  ASAHI shall purchase the shares of common
                    stock by wire  transfer  of the  US$700,000  purchase  price
                    which  must be sent  by  separate  wire  transfer  from  the
                    license  fee defined  above and  received by THERMO no later
                    than June 30, 1999.  THERMO represents and warrants to ASAHI
                    that the shares issued  pursuant to this section are or will
                    be  duly   authorized,   validly   and   fully   paid,   and


<PAGE>5

                    non-assessable  shares,  free and clear of all liens, claims
                    and  encumbrances of any kind. ASAHI represents that it will
                    acquire the Shares for  investment  for its own account only
                    and not with a view to, or for  resale in  connection  with,
                    any  "distribution"   thereof  within  the  meaning  of  the
                    Securities  Act of 1933,  as  amended  ("1933  Act").  ASAHI
                    understands  that the Shares have not been registered  under
                    the 1933 Act, by reason of a specific  exemption  therefrom,
                    which exemption  depends upon, among other things,  the bona
                    fide  nature  of  ASAHI's  investment  intent  as  expressed
                    herein.  ASAHI further acknowledges and understands that the
                    Shares are "restricted securities" within the meaning of SEC
                    Rule 144 and may not be resold unless they are  subsequently
                    registered  under  the 1933 Act or an  exemption  from  such
                    registration is available.  ASAHI further  acknowledges  and
                    understands  that THERMO is under no  obligation to register
                    the  Shares.  ASAHI is aware of the  provisions  of Rule 144
                    promulgated under the 1933 Act, which, in substance, permits
                    limited public resale of "restricted  securities"  (acquired
                    directly or  indirectly,  from the issuer thereof or from an
                    affiliate of such issuer, in a non-public  offering) subject
                    to the satisfaction of certain conditions,  including, among
                    other things:  (i) the  availability , in certain cases,  of
                    certain public information about the issuer; (ii) the resale
                    occurring  not less  than one (1) year  after  the party has
                    purchased and paid for the  securities to be sold; and (iii)
                    in the case of an affiliate, or a non-affiliate who has held
                    the restricted  securities for less than two (2) years,  the
                    sale being made through a broker in an unsolicited "broker's
                    transaction" or in transactions directly with a market maker
                    (as such term is defined under the  Securities  Exchange Act
                    of 1934) and limited to certain amounts as specified in Rule
                    144.

D-1 Section 6.a.3 shall be amended to read as follows:

               a.3  Conformity   THERMO   shall   provide   ASAHI  with  written
                    specifications   (the  "Product   Specifications").   THERMO
                    warrants  that  the  Device,   Container,   Applicators  and
                    Auto-Cryo Kit  manufactured by THERMO shall,  upon tender of
                    delivery  conform  to  all  applicable   specifications  and
                    drawings which are a part of any contractual documents which
                    incorporate  this clause and to any express  representations
                    or  descriptions  contained in such  contractual  documents.
                    THERMO warrants that the System, when operated in accordance
                    with   the   design,    specifications    and    engineering
                    specifications established by THERMO from time to time, will
                    harvest the fibrinogen rich cryoprecipitate through freezing
                    and  thawing  plasma  from a plasma  donor and  prepare  the
                    thrombin  solution  through  activation  of  prothrombin  to
                    thrombin  by   appropriate   chemicals   and  apparatus  and
                    extraction of thrombin from donor's plasma during the thirty
                    (30) days following  installation of the System, normal wear
                    and tear of operating the System  excepted.  Notwithstanding
                    the foregoing, THERMO does not warrant the result of various
                    possible  uses or purposes  for the System,  or warrant that
                    the  System is fit or  intended  for any  particular  use or
                    intended purpose.

D-2 The  following  new  paragraph  shall  be added  to the  Paragraph  8 of the
Agreement:


<PAGE>6



               b.   The  Grant of  Exclusive  License  on the  Licensed  Patents
                    Whenever  the  Licensed  Patents are issued in Japan,  ASAHI
                    shall,  in the name of THERMO  but at  ASAHI's  own cost and
                    expense,  have the right to have the grant of the  Exclusive
                    License set forth in the  article 77 of Japanese  Patent Law
                    on the Licensed Patents  registered with the Japanese Patent
                    Office and THERMO shall cooperate with ASAHI to register the
                    grant of the Exclusive License on the Licensed  Patents.  In
                    this  Amendment,  the  Exclusive  License  shall mean "SENYO
                    JISSIKEN" set forth in the article 77 of the Japanese Patent
                    Law,  of  which  the  grant,   transfer   (except  those  by
                    inheritance or other general  succession),  modification  or
                    extinguishment  (except those resulting form a merger or the
                    extinguishment   of  the  patent  right)  of  which,   or  a
                    restriction  on the disposal  thereof  shall be of no effect
                    unless they are registered.

E.      Section 15.f of the Agreement shall be amended to read as follows:

        15.f   Suspensive Condition.

               (1)    In the event that  THERMO  shall go into  liquidation,  or
                      seek the benefit of any bankruptcy or insolvency act, or a
                      receiver  or  trustee is  appointed  for the  property  or
                      estate of THERMO,  or THERMO makes an  assignment  for the
                      benefit of creditors and as a consequence  THERMO  becomes
                      unable to supply the  Device  and/or  the  Applicators  to
                      ASAHI,  and  whether  any of the  aforesaid  events be the
                      outcome of the voluntary  act of THERMO or otherwise,  and
                      such action or  appointment  remains  undismissed  for 120
                      days, THERMO shall grant to ASAHI the right to manufacture
                      the Device and Applicators  for  distribution in Japan and
                      THERMO,   shall,   as  debtor  in  possession,   take  all
                      appropriate  actions  to  transfer  the  information  from
                      Tashiro Patent Office, located at 2-16, Toranomon 1-chome,
                      Minato-ku, Tokyo 105-0001 Japan, to ASAHI for the required
                      manufacture of the Device and the Applicators.  In case of
                      the occurrence of certain events set forth in this section
                      15.f  (1),  ASAHI  may   manufacture   the  Device  and/or
                      Applicators,  subject to royalty payments for each product
                      manufactured  and in the  percentages set forth in Section
                      3.d  of the  Agreement.  As  long  as  ASAHI  manufactures
                      Devices  and/or  Applicators,  ASAHI may not terminate the
                      Agreement  for the  reasons  set  forth  in  this  Section
                      15.f(1) and (2). When THERMO re-establishes the ability to
                      supply the Devices and/or Applicators,  ASAHI shall have a
                      choice either (a) to continue to  manufacture  the Devices
                      and/or   Applicators;   or  (b)  purchase  Devices  and/or
                      Applicators  from THERMO under the terms and conditions of
                      the Agreement; or elect to do both.

               (2)    Following  certification  from  THERMO  of  Device  and/or

                      production,  if at any  time  THERMO  shall be  unable  to
                      provide ASAHI with the Device and/or Applicators within 90
                      days of the originally promised shipment date for the

                      Device and/or Applicators THERMO, shall grant to ASAHI the
                      right  to  manufacture  the  Device  and  Applicators  for
                      distribution   in  Japan  and   THERMO,   shall  take  all
                      appropriate  actions  to  transfer  the  information  from
                      Tashiro Patent Office, located at 2-16, Toranomon 1-chome,
                      Minato-ku, Tokyo 105-0001 Japan, to ASAHI for the required
                      manufacture of the Device and the Applicators.  In case of
                      the  occurrence  of such  event set forth in this  section
                      15.f(2),   ASAHI  may   manufacture   the  Device   and/or
                      Applicators,  subject to royalty  payments for each Device
                      and Applicator  sold, and in the  percentages set forth in
                      Section   3.d  of  the   Agreement.   As  long  as   ASAHI
                      manufactures  Devices  and/or  Applicators,  ASAHI may not
                      terminate  the Agreement for the reasons set forth in this
                      Section  15.f(1) and (2). When THERMO  re-establishes  the
                      ability to supply the Devices  and/or  Applicators,  ASAHI
                      shall have a choice either (a) to continue to  manufacture
                      the Devices and/or  Applicators;  or (b) purchase  Devices
                      and/or   Applicators  from  THERMO  under  the  terms  and
                      conditions of the Agreement; or elect to do both.

F.      Effect  of  modification.  Except as  modified  by this  Amendment,  the
        Agreement remains in full force and effect.  Unless otherwise  expressly
        defined in Section A of this Amendment, all capitalized terms shall have
        the meaning ascribed to them in the Agreement.

G. The following Section 28 shall be added to the Agreement:

        Except as may be  contemplated  hereunder,  neither  party may issue any
        press   release  or  make  any  public   announcement   concerning   the
        transactions  contemplated  by this Agreement  without the prior written
        consent of the other  party,  except for any  releases or  announcements
        which may be  required  by, or in such  party's  discretion,  reasonably
        necessary  under  applicable  law, in which case the party  proposing to
        make  such  release  or  announcement  will  allow  the  other  party  a
        reasonable  opportunity  to  review  and  comment  on  such  release  or
        announcement in advance of such issuance or making. In addition,  THERMO
        agrees that it will request  under the United  States  securities  laws,
        including Rule 24b-2  promulgated  under the Securities  Exchange Act of
        1934,  as  amended,  and  use  its  reasonable  best  efforts  to  seek,
        confidential   treatment  of  certain  information   contained  in  this
        Agreement.
