                               PROSPECTUS SUMMARY

     This Prospectus contains or incorporates "forward-looking statements,"
which include statements about our business strategy, our growth strategy, our
product development and marketing efforts, and anticipated trends in our
business, which are not historical facts. We may also make additional
forward-looking statements from time to time in filings that we make with the
Securities and Exchange Commission. When we use words like "believe," "expect,"
"anticipate," "project," and similar expressions, this should alert you that the
statement is forward-looking. Forward-looking statements speak only as of the
date made, based largely on expectations. These expectations are generally
subject to a number of risks and uncertainties, some of which cannot be
predicted or quantified, and which are beyond our control. Future events and
actual results may differ materially from the anticipated results expressed in,
contemplated by, or underlying our forward-looking statements. Statements in
this Prospectus, and in documents incorporated by reference into this
Prospectus, including those set forth in the caption "Risk Factors" describe
factors, among others, that could contribute to or cause differences. In light
of these risks and uncertainties, we cannot give any assurances that the
forward-looking information will in fact transpire or prove to be accurate in
the future.


Our Business

     We are a leading developer and manufacturer of micro-manufacturing systems
designed to harvest biopharmaceutical drugs from blood. Biopharmaceutical drugs
utilize the body's naturally occurring proteins, enzymes, growth factors,
hormones and cells to treat human diseases. Our technology platforms are
designed to micro-manufacture biopharmaceutical drugs from a single donation of
blood, in contrast to the manufacture of biopharmaceutical drugs using "pools"
of blood from thousands of donors, or by using expensive technology.

Our Strategy

     Our strategy to take advantage of our market opportunity includes:

o    Utilizing   our   expertise   in   the   areas   of   thermodynamics    and
     cryopreservation;

o    Developing new products through platform designs to build new products with
     only a small incremental research and development investment;

o    Become the leader in the design, development, manufacture, and sale of
     medical devices which produce biopharmaceutical drugs from an autologous or
     directed single donor unit of blood to reduce or eliminate contamination
     and risk of infection to the recipient; and

o    Develop disposable products that are used with our platform designed
     products to provide a recurrent stream of revenue.



Risk Factors

For a discussion of considerations relevant to an investment in our common
stock, see the section entitled "RISK FACTORS" beginning on page 3.

                                               will receive proceeds if certain
                                               outstanding warrants are
                                               exercised. Any proceeds from the
                                               exercise of warrants will be used
                                               for working capital.

                                  RISK FACTORS

     An investment in our common stock involves a number of very significant
risks. Because of these risks, only persons able to bear the risk of and
withstand the loss of their entire investment should invest in our common stock.
Prospective investors should also consider the following before making an
investment decision.

     We Have Incurred Net Losses Since Our Inception and Expect Losses to
Continue. Except for net income of $11,246 for fiscal 1994, we have not been
profitable since our inception. For the fiscal year ended June 30, 2001, we had
a net loss of $6,153,000, and an accumulated deficit at June 30, 2001, of
$44,072,000. For the six months ended December 31, 2001, we had a net loss of
$2,368,000. The report of independent auditors on our June 30, 2001, financial
statements includes an explanatory paragraph indicating there is substantial
doubt about our ability to continue as a going concern. Although we are
executing on our business plan to market launch new products, continuing losses
will impair our ability to fully meet our objectives for new product sales and
will further impair our ability to meet continuing operating expenses. Lack of
operating funds may result in staff reductions and curtailment of clinical
trials currently planned. See Risk Factor entitled "If We Are Unable to Raise
Funds Our Growth May Be Adversely Affected" below.

     If We Are  Unable to Raise  Funds Our  Growth  May Be  Adversely  Affected.
Historically,  we have had to seek capital for our growth and  operations due to
lack of revenues.  Based on proceeds of approximately  $7.0 million (See "Recent
Financing  and Other  Recent  Events" on page 10)  received  in our most  recent
private  placement,  we believe we will have sufficient  working capital for our
next twelve months operations  including  CryoSeal human clinical trial expenses
of  $2.5  million.  However,  if  actual  sales  do not  meet  expectations,  or
marketing,  production and clinical trial costs increase significantly,  we will
need  additional  financing to complete and  implement  our  long-term  business
objectives.  Further,  delays in obtaining required governmental clearances for,
or additional  testing  requirements  prior to,  marketing our new products will
result in  decreased  revenues and  increased  costs that may require us to seek
additional  financing.  In the event  that there is a cash  shortage  and we are
unable to obtain a debt financing,  additional equity financing will be required
which will have the effect of diluting the ownership of existing stockholders.

     We Have Limited Testing Data and Must Complete Further Testing Successfully
in Order To Gain Food and Drug Administration (FDA) Approval Required to Market
our CryoSeal Fibrin Sealant (FS) System in the United States. The Company has
completed certain in vitro and in vivo testing of its CryoSeal FS System, and
further clinical studies are to begin in the near future in Italy, Japan,
Canada, and the United States with the CryoSeal FS System. While these studies
provide a basis to achieve regulatory permission to promote these systems for
some of the indications that management believes can be achieved, they do not
provide a basis to achieve all of the indications. 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
results of operations could be adversely affected.

     Our Failure to Develop New Products Will Adversely Affect Our Future
Growth. Historically, substantially all of our sales have been from products
related to the freezing, thawing, and storing of blood plasma. Because we expect
this segment of the blood plasma market to have limited growth, new products for
the biotechnology market will have to be successfully developed and marketed for
future growth. We are currently focusing on developing and marketing novel blood
processing systems such as the CryoSeal FS System for the automated production
of autologous or allogeneic blood components used as a fibrin sealant. Although
this product uses technology related to our core research, it also represents a
departure from our core blood plasma business. Further, although we have had
discussions with experts in areas of application for these products, these
products are still in their development and/or initial market phase. No
assurance can be given that all of these potential products can be successfully
developed, and if developed, that a market will also develop for them.

     Our Business is Heavily Regulated, Resulting in Increased Costs of
Operations and Delays in Product Sales. Most of our products require FDA
approval to sell in the U.S. and will require clearance from comparable agencies
to sell our products in foreign countries. These clearances may limit the U.S.
or foreign market in which our products may be sold or circumscribe applications
for U.S. or foreign markets in which our products may be sold. The majority of
our products related to freezing blood components are currently exempt from the
requirement to file a 510(k) pre-market application. These products are
currently marketed and sold worldwide. Further, our products must be
manufactured under principals of our quality system for continued Certificate
European (CE) marking that allows our products to be marketed and sold in
Europe, which are similar to the quality system regulations of both the FDA and
California Department of Health. Failure to comply with those quality system
requirements and regulations may subject the Company to delays in production
while it corrects any deficiency found by either the FDA, the State of
California or the Company's notifying European body during any audit of our
quality system. With limited working capital and resources there is no assurance
that we will not be found to be out of compliance, resulting in warning letters
or, in worst case, temporary shut down of manufacturing while the
non-conformances are rectified.

     Influence By the Government and Insurance Companies May Adversely Impact
Sales of Our Products. Our business may be materially affected by continuing
efforts by government, third party payers such as medicare, medicaid, and
private health insurance plans, to reduce the costs of healthcare. For example,
in certain foreign markets the pricing and profit margins of certain healthcare
products are subject to government controls. In addition, increasing emphasis on
managed care in the U.S. will continue to place pressure on the pricing of
healthcare products. As a result, continuing effort to contain healthcare costs
may result in reduced sales or price reductions for our products. To date, we



are not aware of any direct impact on our pricing or product sales due to such
efforts by governments to contain healthcare costs, and we do not anticipate any
immediate impact in the near future.

     Our Inability to Protect Our Patents, Trademarks, and Other Proprietary
Rights Could Adversely Impact Our Competitive Position. We believe that our
patents, trademarks, and other proprietary rights are important to our success
and our competitive position. Accordingly, we devote substantial resources to
the establishment and protection of our patents, trademarks, and proprietary
rights. We currently hold patents for products, and have patents pending for
additional products that we market or intend to market. However, our actions to
establish and protect our patents, trademarks, and other proprietary rights may
be inadequate to prevent imitation of our products by others or to prevent
others from claiming violations of their trademarks and proprietary rights by
us. If our products are challenged as infringing upon patents of other parties,
we will be required to modify the design of the product, obtain a license, or
litigate the issue, all of which may have an adverse business effect on us.

     Failure to Protect Our Trade Secrets May Assist Our Competitors. We protect
our trade secrets and proprietary know-how for our products by various methods,
including the use of confidentiality agreements with employees, vendors, and
customers. However, such methods may not provide complete protection and there
can be no assurance that others will not obtain our know-how, or independently
develop the same or similar technology. We prepare and file for patent
protection on aspects of our technology which we think will be integrated into
final products early in design phases, thereby limiting the potential risks.

     Competition in Our Industry is Intense and Will Likely Involve Companies
With Greater Resources Than We Have. We hope to develop a competitive advantage
in the medical applications of our products, but there are many competitors that
are substantially larger and who possess greater financial resources and
personnel than we have. Our current principal market is the users of ultra-rapid
blood plasma freezing and thawing equipment. There are four companies that sell
freezers to the blood plasma freezing industry which are larger and possess
greater financial and other resources than we do. The CryoSeal FS System may
face competition from major plasma fractionaters that currently sell fibrin glue
sourced from pooled plasma outside the U.S. With regard to the BioArchive
System, numerous larger and better-financed medical device manufacturers may
choose to enter this market as it develops.

     We Have a Limited Marketing and Sales Force for New Products Which May
Delay Our Goal of Increased Sales Levels. We currently sell our existing medical
devices through a direct sales and marketing force, and our foreign distribution
network. Although we have entered into geographically exclusive distribution
agreements for the area of the two new platform products and we continue to seek
strategic partners, there are no assurances that the distributors will sell
significant numbers of the systems.

     Our Lack of Production  Experience May Delay Producing Our New Products. We
currently  manufacture  our blood  plasma  thawers  and  freezers  that are less



technologically sophisticated products. Although we have redesigned our
manufacturing facility to accommodate the BioArchive System and the CryoSeal FS
System, we do not have significant experience in manufacturing those more
complex medical devices or in the manufacture of disposables. Furthermore, there
can be no assurance that our current resources and manufacturing facility could
handle a significant increase in orders for either the BioArchive System or the
CryoSeal FS System. If we are unable to produce enough to meet the demand for
sales of the new systems, we would need to contract with third-party
manufacturers for the backlog, and there are no assurances that a third party
will be available or will produce the systems at favorable prices. Inability to
have products manufactured by third parties at a competitive price will erode
anticipated margins for such products, and negatively impact our profitability.

     Our New Products Are at Initial Market Introduction, and We Are Not Sure
the Market Will Accept Them. The market acceptance of our new products in
development will depend upon the medical community and third-party payers
accepting the products as clinically useful, reliable, accurate, and cost
effective compared to existing and future products or procedures. Market
acceptance will also depend on our ability to adequately train technicians on
how to use the CryoSeal FS System. Even if our new product systems are
clinically adopted, the use may not be recommended by the medical profession or
hospitals unless acceptable reimbursement from health care and third party
payers is available. Failure of either of these new systems to achieve
significant market share could have material adverse effects on our long term
business, financial condition, and results of operation.

     Failure to Keep Our Senior Management Team May Adversely Affect Our
Operations. We are dependent upon the experience and services of Philip H.
Coelho, Chairman and Chief Executive Officer, and James H. Godsey, President and
Chief Operating Officer. The loss of either person would adversely affect our
operations. We have obtained key man life insurance covering Mr. Coelho in the
amount of $2,000,000 as some protection against this risk.

     Product Liability and Uninsured Risks May Adversely Affect Continuing
Operations. We may be liable if any of our products cause injury, illness, or
death. We also may be required to recall certain of our products should they
become damaged or if they are defective. We are not aware of any material
product liability claim against us. Further, we maintain a general liability
policy that includes product liability coverage of $1,000,000 per occurrence and
$2,000,000 per year in the aggregate. However, a product liability claim against
us could have a material adverse effect on our business or financial condition.

     Dependence on Suppliers for Custom Components May Impact the Production
Schedule. The Company obtains certain custom components from one supplier. If
the supplier raises the price of the component or discontinues production, the
Company will have to find another qualified supplier to provide the component.
However, any transfer between qualified suppliers may impact the production
schedule, thus delaying revenues, and/or cause the price of the key components
to increase.

                               THERMOGENESIS CORP.

     We design and sell products and devices which utilize our proprietary
thermodynamic technology for the processing of biological substances, including
the cryopreservation, thawing, harvesting, and archiving of blood components.
Historically, our primary revenues have been from sales of blood plasma freezers
and thawers to hospitals, blood banks, and blood transfusion centers. Currently,
we are manufacturing several categories of thermodynamic devices that are being
sold to the blood plasma industry under FDA clearance to market in the United
States. Other potential markets for our proprietary technology include surgical,
pharmaceutical, and industrial applications. Since fiscal year 1998, we focused
our efforts on research and development and refinement of a core line of
products for blood banks. Since fiscal 1994, we have developed new applications
for our products and technology, including a system for harvesting
cryoprecipitated AHF from a donor's blood plasma for use in the treatment of
hemophilia, and by some physicians as a hemostatic agent or tissue sealant in
certain surgical and medical procedures.

     Our strategy has been to develop superior blood processing  devices for the



niche blood processing markets where new products could quickly establish
credibility for our proprietary technology. We believe that by concentrating our
products to serve the blood plasma industry, many customers, such as the Red
Cross or other blood transfusion societies of various countries, would validate
our proprietary technology for rapid freezing of biological substances, more
specifically blood plasma. Early products, which received 510(k) permission to
market, are sold to blood banks and hospitals either directly or through our
distribution network in the 32 countries where our products are marketed. See
our "Annual Report on Form 10-K. -- Description of the Business."

     From 1988 to 1992, our products were designed to transfer heat by causing
heat transfer liquids to directly contact plastic sealed containers within which
resided various blood components. Early product designs used liquids containing
chloro-flouro-carbons ("CFC") which we phased out in the fall of 1992.
Thereafter, we developed an alternative heat transfer method which automatically
interposed a thin flexible membrane between the heat transfer liquid and
biological substances which process allowed for use of non-CFC based heat
transfer liquids.

     Principal products initially developed by us and marketed to hospitals,
blood banks, and blood transfusion centers consisted of freezers and thawers for
blood plasma. We have continued to design and develop various freezer models and
thawers for expanded applications, and these products remain the core products
of our current business. To expand our market and product use, we have changed
the focus of our research and development to the design of new products that
would be applied to different applications within the blood industry, including
surgical, pharmaceutical, and medical procedures that utilize freezing and
thawing technology as part of standard procedures. See our "Annual Report on
Form 10-K.

     The  Company  previously  engaged  an  investment  banker  to  assist  with
strategic  relationships and direction,  which could include sale of part or all
of the  Company,  or  mergers  with  other  companies.  To  date,  there  are no
definitive agreements with respect to such activities, but the Company continues
to evaluate prospects.

     The Company has  initiated  the pilot for the FDA approved  human  clinical
trials, but has not reported any findings at such an early stage.

Our History

     Our core expertise lies in the technical fields of thermodynamics and
cryopreservation, technologies that we initially applied to the development of
ultra-rapid freezers and thawers, which are currently being sold to blood banks
and hospitals in 32 countries throughout the world. Until the fourth quarter of
fiscal year 1998, our revenues had been principally derived from these products.
Following four years of intensive research and development, we began shipping in
the second quarter of fiscal year 1998 our new platform product called the
BioArchive7 System. The BioArchive System is a computer-controlled liquid
nitrogen platform with dedicated disposables for the collection,
cryopreservation, and archive of blood and blood components. The BioArchive
System is used internationally and in the U.S. as part of a National Heart Lung
and Blood Institute study to process, cryopreserve, and archive hematopoietic
stem and progenitor cells sourced from placental cord blood. These stem cells
are then used to reconstitute the immune system of patients suffering from
leukemia, lymphoma, diverse inherited anemias, or hypoproliferative stem cell
disorders. We have entered into a period of rapid transformation as we begin to
manufacture and market micro-manufacturing systems which may generate recurring
revenues from the ongoing sale of high margin blood processing disposables.


     Our strategy is to utilize our two new technology platforms - the
BioArchive Platform and the CryoSeal FS Platform - as the basis for developing
micro-manufacturing systems to produce biopharmaceutical drugs from either
autologous or single-directed donor blood which will compete in two major
medical markets: Wound Care and Cellular Therapy. Currently, the Company is
aggressively pursuing worldwide strategic partners in an effort to maximize the
value of its new technology platforms.

     We are incorporated in Delaware, and our principal executive offices are
located at 3146 Gold Camp Drive, Rancho Cordova, California 95670 and our
telephone number is (916) 858-5100.

Recent Financing and Other Recent Events

     In March 2002, we completed a private placement of 3,504,310 shares of
common stock, raising an aggregate of $7,008,620, before expenses. Warrants to
purchase 723,362 shares of common stock at an exercise price of $3.07 per share
were also issued. The net proceeds from the private placement are being used to
fund clinical trials through an independent Clinical Research Organization to
support the Company claims for the CryoSeal FS System and for general working
capital. Under the terms of the private placement, we are required to register
for resale the common shares and common shares underlying the warrants.

     In January  2002,  the Company  entered  into a OEM supply  agreement  with
Interpore Cross  International  ("Interpore  Cross") to design and manufacture a
Thrombin Activation Device ("TAD"), a  proprietary-patented  handheld disposable
device that produces 8.5 ml of activated  thrombin  from patient  plasma in less
than one hour.  Interpore  Cross will use the TAD to provde  thrombin as part of
its Autologous Growth  Factors(TM)  (AGF)(TM)  Technology,  which derives from a
patient's blood a cocktail of naturally occurring growth factors and proteins in
high  concentrations  to enhance  the  formation  of new bone cells and  promote
healing at bone graft sites.  Thrombin is used in the AGF  Technology to gel the
fibrinogen-rich AGF concentrate.

     In February  2002, the Company  entered into a distribution  agreement with
Dideco S.p.A., a Snia Group company  ("Dideco")  located in Mirandola,  Italy to
commercialize  our  CryoSeal FS System in Europe,  Eastern  Europe,  portions of
Scandinavia,  the  Middle  East and  Africa.  Dideco is a European  supplier  of
surgical blood management devices, disposables and services. Dideco will promote
our CryoSeal  Fibrin  Sealant for use in both the  autologous  and the allogenic
settings,  emphasizing the ease of use of the product,  the increased safety due
to the lack of bovine  substances  (or any  other  non-human  proteins)  and the
benefits of having additional wound healing proteins present at the wound site.

                             SUMMARY OF THE OFFERING

     We are registering 4,227,672 shares of common stock for resale by the
selling stockholders of which 723,362 shares may be issued upon the exercise of
warrants.

                                 USE OF PROCEEDS

     We will receive no proceeds from the resale of the shares of common stock
by the selling stockholders. We will, however, receive proceeds if the selling
stockholders exercise their warrants. Those proceeds, if any, will be used for
general working capital.

                              PLAN OF DISTRIBUTION

     The selling stockholders, their pledgees, donees, transferees or other
successors in interest may from time to time offer and sell all or a portion of
the shares in transactions on the Nasdaq SmallCap Market, or on any other
securities exchange or market on which the common stock is listed or traded, in
negotiated transactions or otherwise, at prices then prevailing or related to
the then-current market price or at negotiated prices. The selling stockholders
or their pledgees, donees, transferees, or other successors in interest may sell
their shares directly or through agents or broker-dealers acting as principal or
agent, or in block trades or pursuant to a distribution by one or more
underwriters on a firm commitment or best-efforts basis. To the extent required,
the names of any agent or broker-dealer and applicable commissions or discounts



and any other required information with respect to any particular offer will be
set forth in an accompanying Prospectus supplement. Each of the selling
stockholders and their pledgees, donees, transferees or other successors in
interest reserves the right to accept or reject, in whole or in part, any
proposed purchase of the shares to be made directly or through agents.

     In connection with distributions of the shares, any selling stockholder may
enter into hedging transactions with broker-dealers and the broker-dealers may
engage in short sales of the shares in the course of hedging the positions they
assume with the selling stockholder. Any selling stockholder also may sell the
shares short and deliver the shares to close out such short positions. Any
selling stockholder also may enter into options or other transactions with
broker-dealers that involve the delivery of the shares to the broker-dealers,
which may then resell or otherwise transfer such shares. Any selling stockholder
also may loan or pledge the shares to a broker-dealer and the broker-dealer may
sell the shares so loaned or upon a default may sell or otherwise transfer the
pledged shares.

     The selling stockholders, any agents, dealers or underwriters that
participate with the selling stockholders in the resale of the shares of common
stock and the pledgees, donees, transferees or other successors in interest of
the selling stockholders may be deemed to be "underwriters" within the meaning
of the Securities Act, in which case any commissions received by such agents,
dealers or underwriters and a profit on the resale of the shares of common stock
purchased by them may be deemed underwriting commissions or discounts under the
Securities Act.

     There is no assurance that the selling stockholders will sell any or all of
the shares.

     Pursuant to registration rights agreements between us and certain of the
selling stockholders, we have agreed to pay all expenses of the Company and
selling stockholders incurred in the registration of the shares other than
brokerage commissions incurred by the selling stockholders.

     In addition to selling their common stock under this Prospectus, the
selling stockholders may:

     o transfer their common stock in other ways not involving market makers or
established trading markets, including by gift, distribution, or other transfer;
or

     o sell their common stock under Rule 144 of the Securities Act.

                              SELLING STOCKHOLDERS

     The following table identifies the selling stockholders, as of March 26,
2002, and indicates certain information known to us with respect to (i) the
number of shares of common stock held by the selling stockholders, (ii) the



amount to be offered for the selling stockholders' account, and (iii) the number
of shares and percentage of outstanding shares of common stock to be owned by
the selling stockholders after the sale of the common stock offered by the
selling stockholders. The selling stockholders are not obligated to sell their
common stock offered by this Prospectus.

     The number of shares listed under "Shares to be Sold" in the table assumes
that the selling stockholders have exercised their warrants into the maximum
number of shares currently permitted and will sell all common shares in a
secondary offering pursuant to this Prospectus.

     Under the Exchange Act, any person engaged in a distribution of the shares
of our common stock offered by this Prospectus may not simultaneously engage in
market making activities with respect to our common stock during the applicable
periods prior to the commencement of such distribution. In addition, and without
limiting the foregoing, each selling stockholder may be subject to applicable
provisions of the Exchange Act and the rules and regulations thereunder
including, without limitation, Regulation M. Further, the selling stockholders
may resell their shares pursuant to Rule 144.

     The warrants are not registered or listed for trading on the Nasdaq Stock
Market or on any exchange.

     The 723,362 of the shares shown as owned and offered by the stockholders
under this Prospectus may be issued upon exercise of warrants acquired by these
selling stockholders from us in a private placement and resold.

indemnify directors and officers of the company to the fullest extent permitted
by Delaware Law. Further, our bylaws provide authority for the company to
maintain a liability insurance policy that insures directors or officers against
any liability incurred by them in serving for the company.

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

Item 15.  Indemnification of Directors and Officers

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

     Under such law, we are empowered to indemnify any person who was or is a
party or is threatened to be made a party to any proceeding (other than an
action by or in the right of our company to procure a judgment in its favor) by
reason of the fact that such person is or was an officer, director, employee or
other agent of our company or our subsidiaries, against expenses, judgments,
fines, settlements and other amounts actually and reasonably incurred in
connection with such proceeding if such person acted in good faith and in a
manner such person reasonably believed to be in our best interests and, in the
case of a criminal proceeding, has no reasonable cause to believe the conduct of
such person was unlawful. In addition, we may indemnify, subject to certain
exceptions, any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action by or in the right of our company





to procure a judgment in our favor by reason of the fact that such person is or
was an officer, director, employee or other agent of our company or our
subsidiaries, against expenses actually and reasonably incurred by such person
in connection with the defense or settlement of such action if such person acted
in good faith and in a manner such person believed to be in the best interest of
our company and stockholders. We may advance expenses incurred in defending any
proceeding prior to final disposition upon receipt of an undertaking by the
agent to repay that amount it shall be determined that the agent is not entitled
to indemnification as authorized.

     In addition, we have directors' and officers' liability insurance, which
our bylaws provide authority to maintain to insure directors or officers against
any liability incurred while in capacity as such, or arising out of their status
as such.

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

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

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

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

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

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

     (3) To remove from registration by means of a post-effective amendment any

annual report pursuant to section 13(a) or section 15(d) of the Securities
Exchange of 1934 Act that is incorporated by reference in the registration
statement shall be deemed to be a new registration statement relating to the
securities offered herein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.






                                    * * * * *

of 1933 may be permitted to directors, officers and controlling persons of the
Company the foregoing provisions, or otherwise, the Company has been advised
that in the opinion of the Securities and Exchange Commission such

therefore, unenforceable. In the event that a claim for indemnification against

paid by a director, officer or controlling person of the Company in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being

     Re: Common Stock of THERMOGENESIS CORP.

Dear Gentlemen:

     We have acted as general counsel to THERMOGENESIS CORP., a Delaware
corporation (the "Company"), in connection with the registration of 4,227,672
shares of the Company's common stock (the "Shares") under the Securities Act of
1933, as amended (the "Securities Act"), of which 723,362 of the Shares will be
offered to holders of the Company's warrants, and all of which will be sold by
selling stockholders of the Company as further described in the Company's
registration statement on Form S-3 filed under the Securities Act (the
"Registration Statement").

     For the purpose of rendering this opinion, we examined originals or copies
of such documents as deemed to be relevant. In conducting our examination, we
assumed, without investigation, the genuineness of all signatures, the
correctness of all certificates, the authenticity of all documents submitted to
us as originals, the conformity to original documents of all documents submitted
as certified or photostatic copies, and the authenticity of the originals of
such copies, and the accuracy and completeness of all records made available to
us by the Company. In addition, in rendering this opinion, we assumed that the
Shares will be offered in the manner and on the terms identified or referred to
in the Registration Statement, including all amendments thereto.

     Our opinion is limited solely to matters set forth herein. The law covered
by the opinions expressed herein is limited to the Federal Law of the United
States, the law applicable to contracts of the State of California and the law
applicable to corporations of the State of Delaware.

     Based upon and subject to the foregoing, after giving due regard to such
issues of law as we deemed relevant, and assuming that (i) the Registration








April 9, 2002
Page 2

Statement becomes and remains effective, and the Prospectus which is a part of
the Registration Statement (the "Prospectus"), and the Prospectus delivery
requirements with respect thereto, fulfill all of the requirements of the
Securities Act, throughout all periods relevant to the opinion, (ii) all offers
and sales of the Shares will be made in compliance with the securities laws of
the states having jurisdiction thereof, and (iii) the Company receives, to the
extent applicable, the consideration set forth in the warrants, we are of the
opinion that the Shares issued are, and the Shares to be issued will be, legally
issued, fully paid and nonassessable.

     We hereby consent in writing to the use of our opinion as an exhibit to the
Registration Statement and any amendment thereto. By giving such consent, we do
not thereby admit that we come within the category of persons where consent is
required under Section 7 of the Securities Act or the rules and regulations of
the Securities and Exchange Commission.

                                   Sincerely,
