                               PROSPECTUS SUMMARY

         The following summary should be read in conjunction with, and is
qualified in its entirety by, the more detailed information and financial
statements appearing elsewhere in this prospectus.

Company Overview

         BSD Medical Corporation develops, manufactures, markets and services
hyperthermia microwave systems used to treat cancer, the second leading cause of
death in the United States according to the National Cancer Society. Our
treatment systems are designed to precisely deliver microwave energy to elevate
the temperature of cancerous tumors, directly killing cancerous cells and
enhancing the effectiveness of certain other cancer therapies. We also
manufacture products and supply services for TherMatrx, Inc., a privately-held
medical device company in which we have ownership.

         The focus of our cancer therapy business is to develop and
commercialize systems that can provide hyperthermia treatment for cancerous
tumors that occur anywhere in the body. To accomplish this, we have developed
systems capable of treating both superficial and deep tumors. These systems
consist of two families of products, the BSD-500 and the BSD-2000.

         In October 2003, we announced that we had received FDA approval for a
new operating system, allowing us to launch the commercial market introduction
in the United States of a new family of six systems (the BSD-500i-4, BSD-500s-4,
BSD-500c-4, BSD-500i-8, BSD-500s-8 and BSD-500c-8) to treat cancer patients
using superficial and interstitial hyperthermia. We have also obtained CE Mark
certification required to export these systems to Europe. In addition to
treating melanoma, recurring breast cancer and other cancers requiring
superficial therapy, these new systems are used as companions to brachytherapy
systems that treat cancer through interstitial radiation. We believe over 1,500
brachytherapy systems have been installed providing a target customer base for
our systems. These new systems are compact, portable and ergonomically
engineered for use in a demanding hospital environment.

         Our BSD-2000 family of systems employs an advanced phased array of
microwave antennae used to focus on and treat tumors located deep in the body.
The BSD-2000 system has not been submitted for FDA pre-market approval, or PMA.
Accordingly, we do not have authority to distribute the BSD-2000 system for sale
in the United States, except as an investigational device. The phase III
clinical trial through which we intend to seek a PMA for this system has already
been completed, and we are underway in developing the commercial version of the
BSD-2000 that we intend to use as the basis of the FDA submission.

         In addition to systems for treating cancer, we have also developed a
system used in the therapy of a major benign condition. We currently own
approximately 30% of TherMatrx, which markets a medical device that we developed
for the treatment of benign prostatic hyperplasia, or BPH. BPH results from
enlargement of the prostate as men age, and is a major health condition so
prevalent that its symptoms affect over half of men by age 60 and 90% of men by
age 85, according to data presented in a Mayo Clinic and Mayo Foundation study
published in 1995 in the Archives of Internal Medicine. TherMatrx received FDA
approval to market its TMx-2000 thermotherapy system for treating BPH in July
2001, and since then it has been marketing and selling the TMx-2000. TherMatrx
had sales in excess of $13 million and a net income in excess of $1.5 million in
only its second full fiscal year since the FDA approval. In addition to being an
equity owner of TherMatrx, we provide technical and regulatory support services
for TherMatrx on a consulting basis, and manufacture and test some of its
products. In both fiscal 2002 and 2003, TherMatrx was our largest customer.

         Our principal executive offices are located at 2188 West 2200 South,

The Offering

         The selling stockholders identified in this prospectus are selling up
to 2,162,580 shares of our common stock, which they acquired from us in private
placements on November 28, 2003 and December 10, 2003 or will be issued upon the
exercise of warrants issued to a broker-dealer in connection with the private
placements. We will not receive any proceeds from the sale of the shares by the
selling stockholders.

                                  RISK FACTORS


         Our future operating results are highly uncertain. Before deciding to
invest in BSD Medical or to maintain or increase your investment, you should
carefully consider the risks described below, in addition to the other
information contained in this prospectus. The risks and uncertainties described
below are not the only ones that we face. Additional risks and uncertainties not
presently known to us or that we currently deem immaterial may also affect our
business and results of operations. If any of these risks actually occur, our
business, financial condition or results of operations could be seriously
harmed. In that event, the market price for our common stock could decline and
you may lose all or part of your investment.

         We have a history of significant losses and such losses may continue in
the future.

         Since our inception in 1978, our expenses have substantially exceeded
our revenue, resulting in continuing losses and an accumulated deficit of
$20,486,107 at August 31, 2003. In fiscal 2003, we recorded a net loss of
$570,285. Our net loss was primarily due to a write-off of a significant
receivable of approximately $300,000 to bad debt expense, an increase to
inventory reserve of $90,000 and lower overall sales. We may continue to incur
operating losses in the future as we continue to incur costs to develop our
products, protect our intellectual property and expand our sales and marketing
activities. To become profitable we will need to increase significantly the
revenues we receive from sales of our hyperthermia therapy products to sustain
and increase our profitability on a quarterly or annual basis. We may be unable
to do so, and therefore may never achieve profitability.

         Our hyperthermia therapy products may not achieve market acceptance,
which could limit our future revenue and ability to achieve profitability.

         To date, hyperthermia therapy has not been widely accepted by
cancer-treating physicians as an effective treatment of cancer, either in
combination with other available therapies or alone. We believe this is
primarily due to the inability of early hyperthermia therapy technologies to
focus and control heat directed at specific tissue locations and conclusions
drawn in early scientific studies that hyperthermia was only marginally
effective. Additionally, market acceptance depends upon physicians and hospitals
obtaining adequate reimbursement rates from third-party payers to make our
products commercially viable. If our sales and marketing efforts to promote
hyperthermia therapy acceptance in the medical community fail, or third-party
reimbursement rates for hyperthermia therapy are not adequate to make our
products commercially viable, then our future revenue from sales of our products
may be limited, and we may never sustain profitable operations.

                                       2


         We depend upon TherMatrx as our largest customer and, if TherMatrx does
not purchase products and services from us, our revenue will decrease.

         For the year ended August 31, 2003, TherMatrx accounted for $1,454,943,
or approximately 56.55% of our net sales and was our largest customer. We
manufacture, assemble and test TherMatrx's TMx-2000 system, and also supply
equipment components and provide consulting services to TherMatrx. During the
quarter ended November 30, 2003 our sales to TherMatrx declined to $20,592, a
decrease of $326,268 from the quarter ended November 30, 2002. We anticipate
revenue from TherMatrx to be less in our second quarter of 2004, and possibly
the third quarter, than it was in the second and third quarter of 2003. In
addition, we currently expect revenue from TherMatrx to be less in fiscal 2004
than it was in fiscal 2003. TherMatrx is under no contractual obligation to
obtain from us products or manufacturing, assembling, testing and other
services, and is free to seek and obtain such products and services from other
sources. We believe TherMatrx purchases a majority of its products from other
sources. We cannot assure you that we will continue to provide products and
services to TherMatrx, and the loss of TherMatrx as a customer may have a
material adverse effect on our business, if we are unsuccessful in our efforts
to increase sales of our cancer treatment systems.

         Our common stock ownership in TherMatrx is subject to certain rights
and preferences of TherMatrx's preferred stockholders.

         We own 2,520,700 shares of common stock of TherMatrx. As of September
30, 2003, TherMatrx had a total of 3,225,321 shares of common stock outstanding
and 5,175,000 shares of preferred stock outstanding. In addition, TherMatrx had
1,959,478 options to purchase common stock outstanding. The preferred
stockholders of TherMatrx have certain preferential rights to the common
stockholders, including redemption, dividend and approval rights. In connection
with a possible future sale of TherMatrx, the preferred stockholders may require
TherMatrx to redeem 95% of their preferred stock for an amount equal to their
original investment plus any accumulated but unpaid dividends at a rate of 8%
per annum from December 31, 1997 on that amount. The remaining 5% of the
preferred stock held by the preferred stockholders would automatically convert
into 45% of the common stock on a fully diluted basis. Such an election may
reduce the amount of the proceeds from a sale of TherMatrx that we would
otherwise receive.

         We depend on distributors for international sales.

         Historically, our revenues outside the United States have been derived
from sales of hyperthermia therapy systems through third-party distributors. We
have derived most of our revenue from sales in Europe through our distributor
Medizin-Technik, GmbH, which also purchased equipment components and parts from
us. Medizin-Technik sold none of our hyperthermia therapy systems in Europe in
fiscal 2003, and we can provide no assurance that Medizin-Technik's sales will
improve in the future. The loss, or ineffectiveness, of Medizin-Technik as a
distributor and significant customer could have a material adverse effect on our
business.

         Our relationship with Nucletron as our sales representative for our
BSD-500i system may fail to increase our revenue.

         In May 2002, we entered into an agreement with Nucletron B.V. under
which Nucletron became our exclusive sales agent in most of the world for our
BSD-500i interstitial hyperthermia therapy system. Either party may terminate
the agreement with 30 days' advance notice, and the agreement does not require
Nucletron to buy a minimum number of systems from us. To date, we have sold only
one BSD-500i through Nucletron. It is unclear whether we will increase our
revenue through our relationship with Nucletron.

                                       3


         Government regulation has a significant impact on our business.

         Our research and development efforts, our pre-clinical tests and
clinical trials, and the manufacturing, marketing, distribution and labeling of
our products are subject to extensive regulation by the FDA and comparable
international agencies. The process of obtaining FDA and other required
regulatory approvals is lengthy and expensive and our financial resources are
limited.

         We have not yet received pre-market approval for our BSD-2000 systems.
Obtaining these pre-market approvals from the FDA are necessary for us to
commercially market these systems in the United States. We may not be able to
obtain these approvals on a timely basis, if at all, and such failure could harm
our business prospects substantially. Further, even if we are able to obtain the
approvals we seek from the FDA, the approvals granted may include significant
limitations on the indicated uses for which the products may be marketed, which
restrictions could negatively impact our business.

         After a product is approved for commercial distribution by the FDA, we
have ongoing responsibilities under the Federal Food, Drug, and Cosmetic Act and
FDA regulations, including regulation of our manufacturing facilities and
processes, labeling and record-keeping, and reporting of adverse experiences and
other information. Failure to comply with these ongoing requirements could
result in the FDA imposing operating restrictions on us, enjoining or
restraining certain violations, or imposing civil or criminal penalties on us.
The FDA can also recommend prosecution to the Department of Justice.

         Cancer therapy is subject to rapid technological change, and therapies
that are more effective than ours could render our technology obsolete.

         The treatment of cancer is currently subject to extensive research and
development. Many cancer therapies are being researched, and our products may be
rendered obsolete by existing therapies and as a result of therapy innovations
by others. If our products are rendered obsolete, our business will be
substantially impaired.

         We depend on adequate protection of our patent and other intellectual
property rights.

         We rely on patents, trade secrets, trademarks, copyrights, know-how,
license agreements and contractual provisions to establish and protect our
intellectual property rights. Our success will substantially depend on our
ability to protect our intellectual property rights and maintain rights granted
to us through license agreements. Our intellectual property rights may only
afford us limited protection and may not adequately protect our rights or
remedies to gain or keep any advantages we may have over our competitors, which
could harm our business.

         In the past, we have participated in substantial litigation regarding
our patent and other intellectual property rights in the medical device
industry. We have previously filed lawsuits for patent infringement against
three of our competitors and subsequently settled all three of those lawsuits.
Additional litigation against other parties may be necessary in the future to
enforce our intellectual property rights, to protect our patents and trade
secrets, and to determine the validity and scope of our proprietary rights. This
litigation may require more financial resources than are available to us. We
cannot guarantee that we will be able to successfully protect our rights in
litigation. Failure to successfully protect our rights in litigation could harm
our business.

                                       4


         Our directors and executive officers own a sufficient number of shares
of our capital stock to control our company, which could discourage or prevent a
takeover, even if an acquisition would be beneficial to our stockholders.

         Our directors and executive officers own or control approximately 46%
of our outstanding voting power. Accordingly, these stockholders, individually
and as a group, may be able to influence the outcome of stockholder votes,
involving votes concerning the election of directors, the adoption or amendment
of provisions in our certificate of incorporation and bylaws and the approval of
certain mergers or other similar transactions, such as a sale of substantially
all of our assets. Such control by existing stockholders could have the effect
of delaying, deferring or preventing a change in control of our company.

         We are dependent upon key personnel, many of whom would be difficult to
replace.

         Our success will be largely dependent upon the efforts of Paul F.
Turner, our Chairman and Senior Vice President, Hyrum A. Mead, our President,
and Dixie T. Sells, our Vice President of Regulatory Affairs and other key
employees. We do not maintain key-person insurance on any of these employees.
Our future success also will depend in large part upon our ability to identify,
attract and retain other highly qualified managerial, technical and sales and
marketing personnel. Competition for these individuals is intense. The loss of
the services of any of our key personnel, the inability to identify, attract or
retain qualified personnel in the future or delays in hiring qualified
personnel, could make it more difficult for us to manage our business and meet
key objectives, such as the sale of our products and the introduction of new
products, which would harm our business, financial condition and operating
results.

         Because our common stock is traded on the OTC Bulletin Board, your
ability to sell your shares in the secondary trading market may be limited.

         Our common stock currently is traded on the over-the-counter market on
the OTC Bulletin Board. Consequently, the liquidity of our common stock is
impaired, not only in the number of shares that are bought and sold, but also
through delays in the timing of transactions, and lack of coverage by security
analysts and the news media. As a result, prices for shares of our common stock
may be lower than might otherwise prevail if our common stock was quoted on the
Nasdaq Stock Market or traded on a national securities exchange, like The New
York Stock Exchange or American Stock Exchange.

         Because our common stock is a "penny stock," you may have difficulty
selling them in the secondary trading market.

         Federal regulations under the Securities Exchange Act of 1934 regulate
the trading of so-called "penny stocks," which are generally defined as any
security not listed on a national securities exchange or Nasdaq, priced at less
than $5.00 per share and offered by an issuer with limited net tangible assets
and revenues. Since our common stock currently trades on the OTC Bulletin Board
at less than $5.00 per share, our common stock is a "penny stock" and may not be
traded unless a disclosure schedule explaining the penny stock market and the
risks associated therewith is delivered to a potential purchaser prior to any
trade.

         In addition, because our common stock is not listed on Nasdaq or any
national securities exchange and currently trades at less than $5.00 per share,
trading in our common stock is subject to Rule 15g-9 under the Exchange Act.
Under this rule, broker-dealers must take certain steps prior to selling a
"penny stock," which steps include:

                                       5


         o    obtaining financial and investment information from the investor;

         o    obtaining a written suitability questionnaire and purchase
              agreement signed by the investor; and

         o    providing the investor a written identification of the shares
              being offered and the quantity of the shares.

         If these penny stock rules are not followed by the broker-dealer, the
investor has no obligation to purchase the shares. The application of these
comprehensive rules will make it more difficult for broker-dealers to sell our
common stock and our stockholders, therefore, may have difficulty in selling
their shares in the secondary trading market.

         Sales of a substantial number of shares of our common stock in the
public market, including the shares offered under this prospectus and under
other registration statements, could lower our stock price and impair our
ability to raise funds in new stock offerings.

         Future sales of a substantial number of shares of our common stock in
the public market, including the shares offered under this prospectus, or the
perception that such sales could occur, could adversely affect the prevailing
market price of our common stock and could make it more difficult for us to
raise additional capital through the sale of equity securities. We filed this
registration statement pursuant to an agreement with the holders of the common
stock and warrants purchased in our November and December 2003 private
placements. We are required under this agreement to use our reasonable best
efforts to cause this registration statement to remain effective until the
earlier of (1) the sale of all the shares of our common stock covered by this
registration statement; or (2) such time as the selling stockholders named in
this registration statement become eligible to resell the shares of our common
stock pursuant to Rule 144(k) under the Securities Act.

         The market for our stock is limited and our stock price may be
volatile.

         The market for our common stock has been limited due to low trading
volume and the small number of brokerage firms acting as market makers. Because
of the limitations of our market and volatility of the market price of our
stock, investors may face difficulties in reselling shares at attractive prices
when they want to. The following factors could impact the market for our stock
and cause further volatility in our stock price:

         o    announcements of new technological innovations;

         o    FDA and other regulatory developments;

         o    changes in third-party reimbursements;

         o    developments concerning proprietary rights;

         o    third parties receiving FDA approval for competing products; and

         o    and market conditions generally for medical and technology stocks.

         Anti-takeover provisions in our certificate of incorporation may have a
possible negative effect on our stock price.

                                       6


         Certain provisions of our certificate of incorporation and bylaws may
make it more difficult for a third party to acquire, or discourage a third party
from attempting to acquire, control of us. We have in place several
anti-takeover measures that could discourage or prevent a takeover, even if an
acquisition would be beneficial to our stockholders. Increased difficulties for
a third party to acquire us could adversely affect our stock price.


                                 USE OF PROCEEDS

         The shares of common stock offered by this prospectus will be sold by
the selling stockholders, and the selling stockholders will receive all of the
proceeds from sales of such shares. We will not receive any proceeds from sales
of the shares offered by this prospectus.

                                    BUSINESS

Overview

         We develop, manufacture, market and service hyperthermia microwave
systems used to treat cancer, the second leading cause of death in the United
States according to the National Cancer Society. Our treatment systems are
designed to precisely deliver microwave energy to elevate the temperature of
cancerous tumors, directly killing cancerous cells and enhancing the
effectiveness of certain other cancer therapies. We also manufacture products
and supply services for TherMatrx, Inc., a privately-held medical device company
in which we have ownership.

         The focus of our cancer therapy business is to develop and
commercialize systems that can provide hyperthermia treatment for cancerous
tumors that occur anywhere in the body. To accomplish this, we have developed
systems capable of treating both superficial and deep tumors. These systems
consist of two families of products, the BSD-500 and the BSD-2000.

         In October 2003, we announced that we had received FDA approval for a
new operating system, allowing us to launch the commercial market introduction
in the United States of a new family of six systems (the BSD-500i-4, BSD-500s-4,
BSD-500c-4, BSD-500i-8, BSD-500s-8 and BSD-500c-8) to treat cancer patients
using superficial and interstitial hyperthermia. We have also obtained CE Mark
certification required to export these systems to Europe. In addition to
treating melanoma, recurring breast cancer and other cancers requiring
superficial therapy, these new systems are used as companions to brachytherapy
systems that treat cancer through interstitial radiation. We believe over 1,500
brachytherapy systems have been installed providing a target customer base for
our systems. These new systems are compact, portable and ergonomically
engineered for use in a demanding hospital environment.

         Our BSD-2000 family of systems employs an advanced phased array of
microwave antennae used to focus on and treat tumors located deep in the body.
The BSD-2000 system has not been submitted for pre-market approval from the FDA.
Accordingly, we do not have authority to distribute the BSD-2000 system for sale
in the United States, except as an investigational device. The phase III
clinical trial through which we intend to seek a PMA for this system has already
been completed, and we are underway in developing the commercial version of the
BSD-2000 that we intend to use as the basis of the FDA submission.

         In addition to systems for treating cancer, we have also developed a
system used in the therapy of a major benign condition. We currently own
approximately 30% of TherMatrx, which markets a medical device that we developed
for the treatment of benign prostatic hyperplasia, or BPH. BPH results from

                                       7


enlargement of the prostate as men age, and is a major health condition so
prevalent that its symptoms affect over half of men by age 60 and 90% of men by
age 85, according to data presented in a Mayo Clinic and Mayo Foundation study
published in 1995 in the Archives of Internal Medicine. TherMatrx received FDA
approval to market its TMx-2000 thermotherapy system for treating BPH in July
2001, and since then it has been marketing and selling the TMx-2000. TherMatrx
had sales in excess of $13 million and a net income in excess of $1.5 million in
only its second full fiscal year since the FDA approval. In addition to being an
equity owner of TherMatrx, we provide technical and regulatory support services
for TherMatrx on a consulting basis, and manufacture and test some of its
products. In both fiscal 2002 and 2003, TherMatrx was our largest customer.

         BSD was originally incorporated under the laws of the State of Utah on
March 17, 1978. In July 1986, BSD was reincorporated in Delaware.

Cancer and Hyperthermia Therapy

         Despite the massive attention given to cancer prevention and treatment,
the American Cancer Society projects that 1,334,100 new cancer cases will be
diagnosed and that 556,500 Americans will die from cancer during 2003 (up from
555,500 cancer deaths in 2002). Exceeded only by heart disease, cancer, as a
group of diseases, remains the second leading cause of death in the United
States. Cancer develops when abnormal cells in a part of the body begin to grow
out of control and spread, to other parts of the body.

         The primary cancer therapies currently used include:

         o    Radiation therapy, which is treatment with high-energy rays to
              kill or shrink cancer cells. The radiation may come from outside
              of the body (external radiation) or from radioactive materials
              placed directly in a tumor (internal or implant radiation,
              sometimes called brachytherapy).

         o    Chemotherapy, which is treatment with drugs to destroy cancer
              cells.

         o    Surgery, which is the resection, or removal, of a tumor or other
              organ of the body.

         Because cancer remains a significant cause of death, these three cancer
therapies are still grossly inadequate, and an enormous need for better
treatment is obvious. Hyperthermia is an emerging cancer therapy that both kills
cancer cells directly and has been shown to be a potent additive treatment
making certain of the major existing cancer therapies more effective for some
cancers.

         Cancerous tumors are uncontrolled growths of mutated cells that require
more energy to survive than do cells of normal tissue. As cancer cells grow
rapidly, they tend to outstrip their blood supply, leaving them oxygen starved,
since there is not enough blood to carry sufficient oxygen to these cells.
Oxygen starved cancer cells are resistant to radiation therapy because the
destructive power of radiation therapy depends heavily on tearing apart the
oxygen molecules located in cancer cells. When oxygen molecules are torn apart,
they form oxygen radicals that can attack and destroy cancer cell DNA. Blood
depletion also makes cancer resistant to chemotherapy, where blood transport is
required to deliver the drug. Our hyperthermia therapy systems precisely deliver
microwave energy to elevate the temperature of tumors, usually between
40(degree)C and 45(degree)C. The elevated temperatures draw blood to the tumor
as the body's natural response to the stimulus of heat. The increased blood
supply to the tumor improves delivery of drugs to tumors in chemotherapy. It
also delivers more oxygen to the tumor, increasing the effectiveness of
radiation therapy. Many clinical trials performed at major research institutions
in the United States and Europe have shown strong improvements in the results
from both radiation therapy and chemotherapy when hyperthermia is added to the
treatment.

                                       8


         While sensitizing tumors for more effective treatment from radiation
and/or chemotherapy, hyperthermia also destroys cancer cells directly through
damage to the plasma membrane, the cytoskeleton and the cell nucleus, and by
disrupting the stability of cellular proteins. Tumors with poor blood supply
systems lack the natural cooling capacity provided by efficient blood flow in
normal tissues, making them selectively susceptible to the cancer-destructive
effects of hyperthermia therapy. While temperatures between 40(degree)C and
45(degree)C are used to kill cancer cells in combination with radiation and
chemotherapy, higher temperature treatments, called "thermal therapy" or
"thermotherapy," are used when treatment of cancer is accomplished by heat
alone.

         Hyperthermia has other therapeutic uses. It can be used to shrink
tumors prior to surgery, potentially making resection easier or even possible.
Research has shown hyperthermia to be an activator for gene therapies, speeding
gene production (heat mediated gene therapy). Hyperthermia may play a role in
the development of new anti-tumor vaccines that are based on the production of
heat shock proteins. Research has shown hyperthermia to be an angiogenesis
inhibitor, which means it helps prevent cancer from inducing growth of new blood
vessels to expand its blood supply. Hyperthermia could also become a follow-up
therapy for other angiogenesis inhibitors, used in the final destruction of
cancer cells depleted of blood by angiogenesis inhibitor therapy. Hyperthermia
has been shown to improve a patient's quality of life. Even in situations where
there is no hope for survival, hyperthermia may provide benefits through
alleviation of such effects as bleeding, pain and infection.

         Since 1978, we have been heavily involved in developing technological
advances to expand the use of hyperthermia therapy for the treatment of cancer.
Our efforts have included joint work with many notable cancer research centers
in the United States and Europe. In past years funding for our research efforts
has been provided by such sources as the National Institutes of Health in the
United States and major European government agencies. In recent years, we have
focused our efforts in perfecting the technology required to precisely deliver
deep, non-invasive hyperthermia therapy for the treatment of pelvic and other
deep cancers and to demonstrate effective use of deep hyperthermia through
clinical trials. We believe that our BSD-2000 system has emerged from this
development effort as the world's most advanced system for deep hyperthermia
therapy.

         In the opening address at the April 21, 2001 annual meeting of the
North American Hyperthermic Society (sponsored by the Radiologial Society of
North America), P. K. Sneed, M.D. of the University of California at San
Francisco summarized the results of completed randomized clinical trials in
which the effectiveness of radiation therapy combined with hyperthermia therapy
were compared with the results of radiation therapy alone in cancer treatment.
The summary of the report on these trials was that for melanoma, after two
years, local control (local regression or disappearance of the tumor) was 28%
for the control group of patients who received radiation therapy alone versus
46% local control for the patients who received both hyperthermia and radiation
therapy. For recurrent breast cancer, the complete response rate (complete
disappearance of the tumor) increased from 38% for those receiving radiation
therapy alone to 60% for those patients who received both hyperthermia and
radiation therapy. For glioblastoma (brain cancer), the two-year survival rate
for patients who received radiation therapy alone was 15%, compared to 31%
survival rate two years after treatment for those who received both hyperthermia
and radiation therapy. For advanced cervical cancer, the complete response rate
(disappearance of the tumor) rose from 57% for patients who received radiation
treatments alone to 83% for patients receiving both hyperthermia and radiation
therapy. The cervical cancer data was based on the condition of patients three
years after treatment.

Our Products and Services

         We have developed the technology and products required to approach
hyperthermia therapy through three different techniques, which collectively
allow cancer to be treated virtually anywhere in the body:

         o    Superficial hyperthermia non-invasively treats cancerous tumors
              located within a few centimeters of the surface of the body, such
              as melanoma and recurrent breast cancer.

         o    Internal or interstitial hyperthermia treats tumors in combination
              with internal radiation therapy by inserting tiny microwave
              antennae that deliver hyperthermic microwave energy to tumors
              through the same catheters used to deliver radioactive materials,
              or "seeds," to tumors for radiation therapy. This technique can be
              employed in treating prostate cancer, breast cancer, head and neck
              cancer and a variety of other cancer sites.

         o    Deep hyperthermia non-invasively treats tumors located deep within
              the body, including many problematic cancer sites located in the
              pelvis, abdomen and chest areas.

         BSD-500 Systems. Our BSD-500 systems are used to deliver either
superficial or interstitial hyperthermia therapy or both. There are six
configurations of the BSD-500. The BSD-500i-4 and BSD-500i-8 provide
interstitial hyperthermia treatment using four or eight channel generators,
respectively. Each channel can control three interstitial applicators. The
BSD-500c-4 and BSD-500c-8 provide both superficial and interstitial hyperthermia
treatments using four or eight channel generators. These systems include a touch
screen display monitor by which the operator controls the hyperthermia
treatment, computer equipment and software that controls the delivery of
microwave energy to the tumor, and a generator that creates the needed microwave
energy for the treatment. Additionally, the systems include a variety of
applicators, depending on each system configuration. Non-invasive superficial
applicators are used for superficial hyperthermia treatments. For interstitial
hyperthermia treatments, the system may include up to 24 tiny microwave
heat-delivering antennae that are inserted into catheters used in the standard
practice for internal radiation therapy (called brachytherapy).

         In October 2003, we announced that we had received FDA approval for a
new operating system, allowing us to launch the commercial market introduction
of this new family of six systems. Our FDA approval (described as a pre-market
approval, or PMA, the standard FDA approval required to market Class III medical
devices in the United States) for the BSD-500 family of systems is applicable to
the marketing of all six configurations of the BSD-500 in the United States. We
have also certified the BSD-500 systems for the CE Mark, which is required for
export into some European countries. Obtaining FDA approval and CE Mark for the
new BSD-500 operating systems were major milestones for us.

         BSD-2000. The BSD-2000 family of products includes the BSD-2000, the
BSD-2000/3D and the BSD-2000/3D/MR. These systems non-invasively deliver
hyperthermic microwave energy to cancerous tumors, including those located deep
within the body. These systems include a computer and software that control the
delivery of microwave energy to the tumor, a microwave energy generator, an
amplifier that boosts the microwave power, and a special applicator that
delivers the microwave energy to the patient lying in a prone position on a
specially designed support table. The BSD-2000 systems are able to direct, focus
and deliver microwave energy deep within the body by precisely "steering" the
energy to the tumor from an array of cylindrical antennae. The basic BSD-2000
has eight microwave antennae enabling this electronic steering of energy within
the patient's body. The BSD-2000/3D has 24 microwave antennae enabling
additional electronic steering along the long axis of the body. The 3D steering
is particularly useful when implemented with a magnetic resonance system that is
capable of non-invasive 3D imaging showing the heated regions, thus permitting
the 3D steering to more accurately target the energy to the tumor site.

                                       10


         The BSD-2000 systems have not yet received pre-market approval from the
FDA for commercial marketing in the United States, but the BSD-2000 has obtained
an investigational device exemption, or IDE, for sale in the United States for
research purposes only. We have also certified the BSD-2000 family for the CE
Mark required for export into certain European countries. We are engaged in the
extensive and time consuming process of preparing an FDA submission requesting a
PMA for the BSD-2000 based on clinical data we have already obtained. While we
believe that this data has great merit and is worthy of submission, due to the
inherent uncertainties of the FDA approval process there can be no assurance
that FDA approval will be obtained through our submissions.

         Development of the BSD-2000, the BSD-2000/3D and the BSD-2000/3D/MR has
required a substantial effort involving the cooperative work of such American
research institutions as Duke University, Northwestern University, University of
Southern California, Stanford University, University of Utah and University of
Washington St. Louis. Contributing European research institutions include Daniel
den Hoed Cancer Center of the Academisch Ziekenhuis (Rotterdam, Netherlands),
Haukeland University Hospital (Bergen, Norway), Dusseldorf University Medical
School, Tubingen University Medical School, Essen University Hospital, Charite
Medical School of Humboldt University (Berlin), Luebeck University Medical
School, Munich University Medical School Grosshadern, Interne Klinik Argirov of
the Munich Comprehensive Cancer Center, University of Erlangen (all of Germany),
University of Verona Medical Center (Italy), Graz University Medical School
(Austria) and Kantonsspital Aarau (Switzerland).

         BSD-2000/3D. Through research funded by the National Cancer Institute
in the United States and supportive efforts by other domestic and international
research institutions, we enhanced the BSD-2000 to create the new BSD-2000/3D.
The BSD-2000/3D adds three-dimensional steering of deep focused energy, as
opposed to the two-dimensional steering of energy available in the BSD-2000,
delivering even more precise heating to the tumor. As part of our international
collaborative research efforts, sophisticated treatment planning software for
the BSD-2000/3D has also been developed.

         As previously noted, we have not yet submitted to the FDA a pre-market
approval application for the BSD-2000/3D. However, we have obtained the CE Mark
necessary to export the BSD-2000/3D to certain European countries and other
countries requiring CE Mark certification.

         BSD-2000/3D/MR. As a further enhancement of the BSD-2000/3D, we have
added to it the option of concurrent magnetic resonance imaging, or MRI, used
for monitoring of the delivery of deep hyperthermia therapy. Using sophisticated
microwave filtering and imaging software, the BSD-2000/3D/MR allows an MRI
system to be interfaced with and operate simultaneously with a BSD-2000/3D. The
development of MRI treatment monitoring is a significant breakthrough in the
development of hyperthermic oncology primarily because it allows non-invasive
"on-line" review of hyperthermic treatment progress.

         We installed and tested the first BSD-2000/3D/MR system at a leading
German oncological research institution, the Clinic of Medical Oncology of the
Klinikum Gro(beta)hadern Medical School of Ludwigs-Maximilians-Universitat
Munchen, in Munich, Germany. We installed a second BSD-2000/3D/MR system at the
Department of Radiology of Charite University Medical School of Humboldt
University in Berlin, Germany, as part of a collaborative effort with Siemens
Medical Systems. The funding for purchase and development of these systems was
provided by the German government and public foundation funds.

                                       11


         As is the case for the BSD-2000/3D, we have not yet submitted to the
FDA a pre-market approval application for the BSD-2000/3D/MR. We can, however,
market the BSD-2000/3D/MR in Europe as we have CE Mark approval for the
BSD-2000/3D and only need to ensure that we interface the system with an MRI
system that also is approved in Europe.

         Other Products and Services. In addition to our hyperthermia therapy
systems, we manufacture for, and supply treatment systems and related equipment
components to, other medical device companies, as described below.

         TherMatrx, Inc. We manufacture, assemble and test for TherMatrx its
FDA-approved TMx-2000 thermotherapy system that treats benign prostatic
hyperplasia, or BPH, a condition associated with an enlarged prostate that
commonly affects men over age 50. We also supply TherMatrx with equipment
components used for its TMx-2000 system, including probes, applicators and
temperature components. We also have provided regulatory compliance and other
consulting services to TherMatrx.

         In November 1997, we entered into an agreement with Oracle Strategic
Partners and Charles Manker to form TherMatrx as a jointly-owned private
company. In return for an equity interest in TherMatrx, we transferred to
TherMatrx four patents related to the thermal treatment of BPH. Currently, we
own approximately 30% of TherMatrx.

         TherMatrx's TMx-2000 system is a non-surgical, catheter-based therapy
that has been shown to provide safe and effective relief from BPH symptoms. The
treatment can be performed in a clinic or physician's office. The therapy avoids
the side effects and complications of surgery. TherMatrx obtained FDA approval
to begin marketing its products in July of 2001 and began marketing the TMx-2000
shortly after receiving FDA approval.

         In manufacturing, assembling and testing the TMx-2000 system and
supplying equipment components and providing consulting services to TherMatrx,
TherMatrx has been our largest customer. For the year ended August 31, 2003,
TherMatrx accounted for $1,454,943, or approximately 56.55% of our revenue. Our
product sales to TherMatrx dropped significantly during the first quarter of
fiscal 2004 compared to first quarter of fiscal 2003 because of TherMatrx's
existing excess inventory. TherMatrx is under no contractual obligation to
obtain from us products or manufacturing, assembling, testing or other services,
and is free to obtain such products and services from another source at any
time. We believe TherMatrx purchases majority of its products from other
sources.. We have helped facilitate the availability of this other source of
manufacturing, assembly and testing of the TMx-2000 system, as we believed this
would allow TherMatrx to operate more independently from us. We believe
TherMatrx's increased operational independence from us will increase its value
and that the potential value of our equity ownership in TherMatrx will be more
valuable to us than the revenue we generate from sales of products to TherMatrx.
We cannot assure that we will continue to provide such services to TherMatrx,
and the loss of TherMatrx as a customer would have a material adverse effect on
our business, if we are unsuccessful in our efforts to increase sales of our
cancer treatment systems.

         Medizin-Technik GmbH. Additionally, we supply equipment components to
Medizin-Technik located in Munich, Germany, which is a significant distributor
of our hyperthermia therapy systems in Europe. Medizin-Technik purchases
equipment and components to service our hyperthermia therapy systems that it
sells to its customers in Europe. The President and Chief Executive Officer of
Medizin-Technik is Dr. Gerhard W. Sennewald, one of our directors and
significant stockholders. Medizin-Technik was a significant customer for us in
fiscal 2003 with sales of $517,979 or 20.13% of our revenue. Medizin-Technik has
been a significant customer in prior years and we anticipate that it will be a
significant customer for us in the future. The loss of Medizin-Technik as a
distributor and significant customer would have a material adverse effect on our
business. The distribution rights of Medizin-Technik have been in place since
the early 1980s.

Sales, Marketing and Distribution

         In the United States, our target market includes clinics, hospitals and
institutes in which cancer is treated. In the international market we similarly
target cancer treatment centers in clinics, hospitals and institutes.

         We have entered into an agreement with Nucletron B.V., based in the
Netherlands, under which Nucletron became our exclusive worldwide sales agent,
except in Germany, Austria, Switzerland, Italy and China, for our BSD-500i
interstitial hyperthermia therapy system. Nucletron is one of the leading
providers of high-dose internal radiation therapy throughout the world. Because
our interstitial hyperthermia therapy is typically administered in combination
with internal radiation therapy, such as that provided by Nucletron, we believe
our relationship with Nucletron could be strongly complementary. Nucletron has
over 1,500 radiation therapy systems installed in cancer treatment centers
throughout the world, and we anticipate Nucletron will primarily target these
customers as prospective customers for the enhanced BSD-500i. Our agreement with
Nucletron can be terminated by either party on thirty days prior written notice.
Three months prior to the renewal date of the agreement (which extends until May
1, 2004), the parties may negotiate the conditions of the extension of the
agreement or the conversion of the agreement into a full distribution agreement.
Nucletron has a first right of refusal to obtain exclusive distribution rights
to sell our BSD-500i in its current territory as our sales agent if Nucletron
performs adequately under our current sales agent agreement.

         For our other products that deliver deep hyperthermia therapy,
including the BSD-2000 and related products, we sell our equipment directly to
end-users in the United States. We make international sales of these products
through distributors located in various foreign countries. Medizin-Technik is a
significant distributor of our hyperthermia therapy systems in Europe.

         Our sales and marketing strategy involves three main components:

         o    promoting acceptance by the scientific community and
              cancer-treating healthcare professionals of hyperthermia therapy
              as a viable and effective therapy for treating cancer, either in
              combination with other therapies or as a stand alone therapy;

         o    disseminating information about and marketing our hyperthermia
              therapy systems to the scientific community, cancer-treating
              healthcare professionals, cancer patients and the general public;
              and

         o    working to continuously improve third-party reimbursement for
              medical services performed with our products.

         We disseminate information about our company and our hyperthermia
therapy systems by encouraging articles about hyperthermia therapy to be
published in scientific journals, periodicals and other publications, and
promoting dissemination of BSD information through television, radio and other
media outlets. We post information about our products on our web site,
www.bsdmc.com, and our materials are also posted on many other sites. We have
developed promotional materials for our products, including product brochures,
patient brochures and newsletters. We also participate actively in trade shows
and scientific symposia, make public presentations delivered by our scientific
staff and by scientists and researchers using our systems, and we actively
participate in a variety of medical associations. We are also co-sponsors of the
annual international BSD Users' Conference in Europe. We also believe that the
anticipated active marketing efforts of Nucletron will improve dissemination of
information about us and our products and improve acceptance of our hyperthermia
therapy systems because Nucletron is well-established as an industry leader in
internal radiation therapy and has established relationships with many
cancer-treating healthcare professionals throughout the world.

                                       13


Third-Party Reimbursement

         We view obtaining adequate third-party reimbursement arrangements as
essential to achieving commercial acceptance of our hyperthermia therapy
products. Our products are purchased primarily by clinics, hospitals and other
medical institutions that bill various third-party payers, such as Medicare,
Medicaid, other government programs and private insurance plans for the health
care services provided to their patients using our products. Additionally,
managed care organizations and insurance companies directly pay for services
provided to their patients. The Center for Medicare and Medicaid Services, or
CMS, has established 23 billing codes that allow for third-party reimbursement
and can be used for or in combination with the delivery of hyperthermia therapy,
depending on the circumstances of the treatment. Codes have been established for
billing for superficial and interstitial hyperthermia delivered using our
BSD-500 systems when used in combination with radiation therapy or chemotherapy.
Codes also have been established for providing deep hyperthermia therapy.
Billing codes are available for both institutions and physicians.

         Effective November 1995, HCFA, the predecessor agency to CMS,
authorized Medicare reimbursement for certain investigational devices and
certain related services for which underlying questions of safety and
effectiveness of that device type have been resolved, based on categorization by
the FDA. Our BSD-2000 system, which has been given IDE status by the FDA, has
been placed in this category by the FDA, and thus may be reimbursed by Medicare.

         General hyperthermia reimbursement has been approved in the United
States, Germany, Holland, Switzerland and Japan. CMS has also provided billing
codes for thermotherapy/thermal therapy treatment of BPH. These billing codes
apply to TherMatrx's TMx-2000 system treatments of BPH.

         Even though a new medical device may have been approved for commercial
distribution, we may find limited demand for that product until reimbursement
approval is obtained from governmental and commercial third party payors of
health care. In addition, even after we receive reimbursement approval, or
coverage, of a product, medical reimbursement rates are unpredictable. Both
government and commercial third party payors of health care are seeking to limit
the growth of health care costs. If clinics, hospitals, and other health care
providers are not reimbursed adequately for our product, they may not purchase
our product. We cannot project the extent to which our business may be affected
by future legislative and regulatory developments, and private sector
initiatives, to reduce health care costs. We cannot assure that future health
care legislation or regulation will not have a material adverse effect on the
coverage of our products, our business, financial condition and results of
operations, or that reimbursement, existing or in the future, will be adequate
to ensure that customers continue to purchase our products.

Competition

         Competition in the medical products industry is intense. We believe
that established product lines and cancer therapies, FDA approvals, know-how and
reputation in the industry are key competitive factors. Currently, only a few
companies besides BSD have received FDA approval to manufacture and sell
hyperthermia therapy systems within the United States, including U.S.
Labthermics and Celsion Corporation. Celsion is principally involved with
clinical trials related to thermotherapy, hyperthermia and related fields.
Labthermics produces ultrasound based systems which compete with our microwave
hyperthermia systems. Several other companies have received IDEs in the United
States or other international clearance for certain experimental hyperthermia
systems designed to treat both malignant and benign diseases. Additionally,
other companies, particularly established companies that currently manufacture
and sell other cancer therapy systems, could potentially become competitors (in
that they are also engaged in cancer treatment businesses), and they have
significantly greater resources than we do.

                                       14


         BSD participates in the BPH market as an investor in TherMatrx. In the
BPH market, competitive companies offering products similar to TherMatrx's
products include Urologix and Dornier (which both have received pre-market
approvals from the FDA for their treatment systems), VidaMed, a subsidiary of
Medtronics (which has 510(k) clearance from the FDA) and other foreign
manufacturers. These competitors have significantly greater resources than
TherMatrx and may be better positioned to compete in TherMatrx's market. In
addition to thermotherapy equipment made by TherMatrx's competitors, there are
other competitive treatments for BPH that are currently being developed,
clinically investigated and/or actively marketed.

Product Service

         We provide a 12-month warranty following installation on all cancer
treatment systems and a 90-day limited warranty on individual components. We
install and service the hyperthermia systems we sell to domestic customers. In
addition, we or our consultants provide technical and clinical training to our
customers. Subsequent to the applicable warranty period, we offer our domestic
customers full or limited service contracts.

         Generally, our distributors install and service systems sold to foreign
customers and are responsible for managing their own warranty programs for their
customers, including labor and travel expenses. We provide warranties for the
replacement and/or repair of parts for 12 months for systems sold
internationally through distributors and for 90 days for individual components.
Spare parts are generally purchased by the distributors and stored at the
distributors' maintenance facilities to allow prompt repair. Distributor service
personnel are usually trained at customer sites and at our facilities in Salt
Lake City, Utah.

Production

         We manufacture and test our systems and products at our facilities in
Salt Lake City, Utah. Our manufacturing facility is ISO 9001-1994 certified and
follows FDA quality systems regulations. Some equipment components we purchase
from suppliers are customized to our specifications. Key factors in our
manufacturing process are assembly and testing. We purchase component parts and
other materials from a variety of suppliers. We do not depend on a single
supplier for any item, and believe we can acquire materials and parts from
multiple sources on a timely basis.

Product Liability Exposure

         The manufacturing and marketing of medical devices involves an inherent
risk of product liability. Because our products are intended to be used in
hospitals on patients who may be physiologically unstable and severely ill, we
are exposed to potential product liability claims. We presently carry product
liability insurance with coverage limits of $1 million. However, we cannot
assure you that our product liability insurance will provide adequate coverage
against potential claims that might be made against us. No product liability
claims are presently pending against us; however, we cannot assume that product
liability claims will not be filed in the future or that such claims will not
exceed our coverage limits.

                                       15


Government Regulation

         The medical devices that we have developed and are developing are
subject to extensive and rigorous regulation by numerous governmental
authorities, principally by the United States Food and Drug Administration, or
FDA, and comparable foreign agencies. Pursuant to the Federal Food, Drug and
Cosmetic Act, as amended, the FDA regulates and must approve the clinical
testing, manufacture, labeling, distribution, and promotion of medical devices
in the United States.

         Most of our hyperthermia treatment systems, including the BSD-500 and
the BSD-2000 and related products, have required or require pre-market approval
from the FDA instead of the simpler 510(k) approval, and we anticipate that our
future systems will similarly require pre-market approval. Pre-market approval
requires that we demonstrate that the medical device is safe and effective. To
do this, we conduct either laboratory and/or clinical testing. The FDA will
grant approval of the product if it determines there is reasonable assurance
that the medical device is safe and effective. FDA approval must be obtained
before commercial distribution of the product. We intend to continue to make
improvements in and to our existing products. Significant product changes must
be submitted to the FDA under investigational device exemptions, or IDEs, or
pre-market approval supplements. As described in the Section entitled "Our
Products and Services" above, we have obtained a PMA for our BSD-500 systems and
IDE status for our BSD-2000 system.

         Various foreign countries in which our products are or may be sold,
have regulatory requirements that can vary widely from country to country. Sales
into the European Union, or EU, require compliance with the Medical Devices
Directive, or MDD, and require us to obtain the necessary certifications to have
a CE Mark affixed to our products. We have obtained necessary ISO certification
of our quality, development, and manufacturing processes, and we have
successfully completed the CE Mark testing and Annex II audit. This allows us to
certify our own products and to affix the CE Mark label on them. However, we
must maintain compliance with all current and future directives and requirements
to maintain ISO certification and to continue to affix the CE Mark, and there
can be no assurance that we will continue to maintain compliance with regulatory
requirements imposed on us.

         After we receive FDA approval to distribute a medical device, we
continue to have ongoing responsibilities under the Federal Food, Drug, and
Cosmetic Act and FDA regulations. The FDA reviews design and manufacturing
practices, labeling, record-keeping, and required reporting of adverse
experiences. All medical devices must be manufactured in accordance with
regulations specified in the FDA Quality System regulations, or QSR, and in
compliance with the ISO and other applicable standards. In complying with these
regulations, we must continue to expend time, money and effort in the areas of
design control, production, and quality control to ensure full compliance. The
FDA's mandatory Medical Device Reporting regulation requires us to provide
information to the FDA on death or serious injuries alleged to have been
associated with the use of our products, as well as information on product
malfunctions that would likely cause or contribute to a death or serious injury
if the malfunctions were to recur. In Europe, the MDD vigilance system
regulations require that we, through a representative in Europe, provide
information to authorities on death or serious injuries alleged to have been
associated with the use of our products, as well as information on product
malfunctions that would likely cause or contribute to a death or serious injury
if the malfunctions were to recur. If FDA were to assert that we are not in
compliance with applicable laws or regulations, or that any of our medical
devices are ineffective or pose an unreasonable risk to patient health, the FDA
could seize our medical devices, ban such medical devices, or order a recall,
repair, replacement or refund of such devices, and require us to notify health
care professionals and others that the devices present unreasonable risk of
substantial harm to the public. The FDA may also impose operating restrictions,
restrain certain violations of law, and assess civil or criminal penalties
against us. The FDA can also recommend prosecution to the Department of Justice.
Certain regulations are subject to administrative interpretation, and we cannot
assure that future interpretations made by the FDA or other regulatory bodies,
with possible retroactive effect, will not adversely affect us.

                                       16


         International sales of medical devices are subject to FDA export
requirements. We have obtained export approvals for all countries into which we
have delivered products. This includes countries in Western Europe and much of
Eastern Europe and many Asian countries.

         International sales are subject to the regulatory and safety
requirements of the country into which the sale occurs. There can be no
assurance that all of the necessary approvals will be granted on a timely basis
or at all. Delays in receipt of or failure to receive such approvals would have
a material adverse effect on our financial condition and results of operations.

         In addition to FDA regulations, certain U.S. health care laws apply
when a claim for reimbursement for one of our medical devices is submitted to
Medicare, Medicaid, or other federal health care programs. For instance, federal
law prohibits the filing of false or improper claims for federal payments. In
addition, federal law prohibits the payment of anything of value for the purpose
of inducing referrals of business reimbursable under a federal health care
program. Other federal laws prohibit physicians from making referrals for
certain services and items payable under certain federal programs if the
physician has a financial relationship with the entity providing the service or
item.

         All of these laws are subject to evolving interpretations. If the
federal government were to conclude that we are not in compliance with any of
these health care laws, we could be subject to substantial criminal and civil
penalties, and could be excluded from participation as a supplier to
beneficiaries in federal health care programs.

         The Federal Communications Commission, or FCC, regulates the
frequencies of microwave and radio frequency emissions from medical and other
types of equipment to prevent interference with commercial and governmental
communications networks. The BSD-500 fixed frequency systems and applicators
emit 915 MHz for U.S. and some European installations and 433.92 MHz for some
European installations, which is approved by the FCC for medical applications.
Accordingly, these systems do not require shielding to prevent interference with
communications. Our BSD-2000 deep hyperthermia variable-frequency generators and
applicators require electromagnetic shielding.

Patents, Licenses, and Other Rights

         Because of the substantial length of time and expense associated with
bringing new products through development and regulatory approval to the
marketplace, the medical device industry places considerable importance on
obtaining patent and trade secret protection for new technologies, products and
processes. Our policy is to file patent applications to protect significant
technology, inventions and product improvements. We currently own six patents in
the United States and two patents outside the United States. Four additional
patents were assigned to TherMatrx, for which we obtained a license, and one
patent license was obtained by us from University of California San Francisco
and another license was obtained by us from the National Institutes of Health. A
European patent for the BSD-2000/3D system has been issued. We believe that our
patents represent the early pioneering and dominant patents in this field. These
patents along with the advanced product development and leadership in the field
are key elements for our current and future market position.

         In July 1979, we entered into an exclusive worldwide license for a
unique temperature probe called the Bowman Probe. The license will remain in
effect as long as the technology does not become publicly known as a result of
actions taken by the licensor. We pay royalties based upon our sales of the
Bowman Probe. The license agreement was amended and renewed in August 2000 and
is currently in effect.

                                       17


         On October 21, 1999, we acquired from the University of California San
Francisco (UCSF) the exclusive patent license (U.S. Patent 4,825,880) for small
microwave antennae that can be inserted into cancerous tumors to destroy them
from the inside. The innovative microwave antenna design enables the therapeutic
heating length to be tailored to match the tumor size. This license requires
payment of 2.5% of sales on licensed products sold and payment of patent
maintenance fees and other annual payments of $4,000 to maintain the exclusive
license. We remain current on these payments.

         BSD also acquired on December 13, 2001 a patent license from the
National Institutes of Health (NIH) for the U.S. Patent 5,284,114. This patent
is for the combination of magnetic resonance integrated hyperthermia systems,
including our BSD-2000/3D/MR system, and is based on a patent obtained by NIH in
early research of the concept. The license agreement requires annual payment of
$1,000, $4,000 per licensed product sold in the U.S., and $1,000 per licensed
product manufactured in the U.S. and sold outside the U.S. There is also to be a
single payment of $10,000 upon PMA or 510(k) FDA approval.

         On July 1, 2001, we acquired the rights to all FDA approvals and the
rights to manufacture all cancer products formerly owned by Clini-Therm Corp.
These products are related to the hyperthermia therapy delivered by our BSD-500
systems, the exclusive patent obtained from UCSF, and our enhancements to such
systems involve incorporating some of the Clini-Therm rights we acquired into
such systems. This involved only a one-time cash payment with no continuing
costs.

         From time to time, we have had and may continue to have discussions
with other companies, universities and private individuals concerning the
possible granting of licenses covering technology and/or patents. There can be
no assurance that such discussions will result in any agreements. In the past,
we have granted non-exclusive practice licenses for a few selected patents to
three companies. One of these companies is no longer in business.

         We cannot assure that the patents presently issued to us will be of
significant value to us in the future or will be held valid upon judicial
review. Successful litigation against these patents by a competitor would have a
material adverse effect upon our business, financial condition and results of
operations. We believe that we possess significant proprietary know-how in our
hardware and software capabilities. However, we cannot assure that others will
not develop, acquire or patent technologies similar to ours or that such secrecy
will not be breached.

Research and Development

         During the fiscal years ended August 31, 2003, and August 31, 2002, we
expended $676,867 and $603,137 respectively for research and development,
representing 26.30% and 22.56% of total revenues. Research and development
expenditures increased in fiscal 2003 due to costs associated with the
development of the BSD-2000/3D/MR system, the continued enhancements of our
BSD-500 systems and the development of new products not yet announced.
Technological changes play an important part in the advancement of our industry.
We intend to continue to devote substantial sums to research and development.
Research and development efforts inherently involve risks and uncertainties that
could aversely affect our projections, outlook and operating results.

Employees

         As of January 23, 2004, BSD had 26 employees; 22 of whom were full time
employees. None of our employees is covered by a collective bargaining
agreement. We consider our relations with our employees to be satisfactory. We
depend upon a limited number of key management, manufacturing, and technical
personnel. Our future success will depend in part on our ability to retain these
highly qualified employees.

                                       18


Properties

         Our office, production and research facilities are located in Salt Lake
City, Utah. The complete headquarters and production facility occupies
approximately 20,000 square feet. We have leased the building for an annual
rental expense of approximately $78,000. In November 2002, we renewed our lease
for five years, which includes payments of approximately $82,000 per year for
five years adjusted annually for increases in the cost of living based on the
Consumer Price Index for Urban Consumers. We have an option to purchase the
building for $1,000,000 upon 60 days notice for six years beginning December 1,
2002. Thereafter, the purchase price increases by $50,000 each year, and the
option expires at the end of the tenth year. The building lease is accounted for
as an operating lease for financial statement purposes. The building is
currently in good condition, is adequate for our needs, is suitable for all
company functions and provides room for future expansion. We believe that we
carry adequate insurance on the property.

Legal Proceedings

         There are no legal proceedings pending against or being taken by us.

Audit Committee

         We have established an audit committee, which consists of Mr.
Sennewald, Mr. Short and Mr. Nobel. The audit committee is responsible for
reviewing and monitoring our financial statements and internal accounting
procedures, recommending the selection of independent auditors by our board,
evaluating the scope of the annual audit, reviewing audit results, consulting
with management and our independent auditor prior to presentation of financial
statements to stockholders and, as appropriate, initiating inquiries into
aspects of our internal accounting controls and financial affairs. We currently
do not have an audit committee financial expert because of our relatively small
size and our limited resources to attract such an expert.

                             EXECUTIVE COMPENSATION

         (1) Represents options to purchase shares of TherMatrx common stock we
owned on the date of grant. These options were granted by us in July 2002 and
were exercised in the fourth quarter of fiscal 2002 at an exercise price per
share of $0.001. We recognized a compensation expense related to these TherMatrx
options computed using a value of $4.00 per share. The $4.00 per share value is
based solely on the price per share for common stock sold by TherMatrx to
existing TherMatrx stockholders in December 2001.

         The following table summarizes the exercise of stock options during
fiscal 2003 by Messrs. Turner and Mead, and the fiscal year-end value of
unexercised stock options held by each of them. None of these executive officers
exercised stock options during fiscal 2003.

share of our common stock at August 31, 2003 $0.79, and the exercise price of
the options ranging from $0.10 to $0.81 per share. Options are in-the-money if
the market price of the shares exceeds the option exercise price.

Compensation of Directors

         We provide annual compensation in the amount of $12,000 to each
non-employee director. Of this amount, $4,000 is to be paid in cash and the
balance is to be paid in the form of restricted shares of our common stock under
our 1998 Director Stock Option Plan. In addition to the annual compensation to
directors, each non-employee director will receive an annual option to purchase
25,000 restricted shares of our common stock at a purchase price of 85% of the
fair market value at the date the option is granted. The options vest ratably
over 5 years and expire in 10 years.

         Paul F. Turner and Hyrum A. Mead are the only members of the Board of
Directors who are employed by us. Messrs. Turner and Mead do not receive any
separate compensation for services performed as directors.

Employment Contracts

         We entered into an employment agreement with Mr. Mead dated August 10,
1999. This agreement provides that Mr. Mead shall receive an annual base salary
of $125,000, which shall be reviewed annually by the Board of Directors. The
agreement provides that if Mr. Mead is involuntarily terminated, Mr. Mead will
receive severance compensation for a period of six months, including an
extension of all benefits and perquisites. The severance amount shall include
six month's of salary at the highest rate paid to Mr. Mead prior to termination
and an additional amount equal to all bonuses received by Mr. Mead during the
12-month period preceding termination (excluding any signing bonus received
during such period). The agreement also requires us to vest any options granted
to Mr. Mead for the purchase of our common stock, allowing a 90-day period for
Mr. Mead to exercise those options. Mr. Mead's agreement includes a
non-competition covenant prohibiting him from competing with us for one year
following his termination.

         We entered into an employment agreement with Mr. Turner dated November
2, 1988. The agreement provides that Mr. Turner's salary will be based upon a
reasonable mutual agreement. The agreement provides that if Mr. Turner's
employment is involuntarily terminated, he will receive severance pay for a
one-year period, which pay includes an extension of all of his rights,
privileges and benefits as an employee (including medical insurance). The one
year severance pay shall be equal to Mr. Turner's regular salary for the

                                       22


12-month period immediately prior to the termination. The agreement also
requires us to pay Mr. Turner for any accrued unused vacation at the time of
termination. We are also obligated to pay Mr. Turner $1,000 (or the equivalent
value in stock options) for each newly issued patent obtained by us as a result
of Mr. Turner's efforts (Mr. Turner receives only $500 if multiple inventors are
involved). Mr. Turner's agreement includes a non-competition covenant
prohibiting him from competing with us for one year following his termination.
We may continue the non-competition period for up to four additional years by
notifying Mr. Turner in writing and by continuing the severance payments for the
additional years during which the non-competition period is extended.

                              SELLING STOCKHOLDERS

         The following table sets forth the number of shares of our common stock
beneficially owned by the selling stockholders as of January 23, 2004, based on
the selling stockholders' representations regarding their ownership. The
percentages shown in the table are based on 19,915,232 shares of common stock
outstanding on that date. We cannot estimate the number of shares that will be
held by the selling stockholders after completion of this offering because the
selling stockholders may sell all or some of the shares and because there
currently are no agreements, arrangements or understandings with respect to the
sale of any of the shares. The term "selling stockholder" or "selling
stockholders" includes the stockholders listed below and their transferees,
assignees, pledgees, donees or other successors. Each selling stockholder
reserves the right to accept or reject, in whole or in part, any proposed sale
of shares. Each selling stockholder also may offer and sell less than the number
of shares indicated. No selling stockholder is making any representation that
any shares covered by this prospectus will or will not be offered for sale.
Except as indicated in this section, we are not aware of any material
relationship between us and a selling stockholder within the past three years
other than as a result of a selling stockholder's beneficial ownership of our
common stock.

         Unless otherwise indicated in the table below, the shares being offered
in this prospectus were issued to seven accredited investors pursuant to that
certain Securities Purchase Agreement dated as of November 28, 2003, and as
amended on December 10, 2003, (the "Purchase Agreement") between us and these
investors. In accordance with the terms and conditions of the Purchase
Agreement, we issued an aggregate of 2,059,600 shares of common stock. We also
issued a three-year, immediately exercisable warrant to purchase up to 102,980
shares of common stock at an exercise price of $1.80 per share (the "Warrant")
to a broker-dealer in connection with the Purchase Agreement. The shares to be
issued upon exercise of the Warrant are also being offered in this prospectus.

                              PLAN OF DISTRIBUTION

         We have registered the 2,162,580 shares of our common stock offered in
this prospectus on behalf of the selling stockholders. We will pay all expenses
of this registration, other than fees and expenses, if any, of counsel or other
advisors to the selling stockholders. The selling stockholders are responsible
for paying any commissions, discounts, or other brokerage fees incurred in
connection with their sale of any of the shares.

                                       24


         The shares of common stock may be sold in one or more transactions at
fixed prices, at prevailing market prices at the time of sale, at prices related
to the prevailing market prices, at varying prices determined at the time of
sale, or at negotiated prices. These sales may be effected at various times in
one or more of the following transactions, or in other kinds of transactions:

         o    in the over-the-counter market;

         o    in private transactions and transactions otherwise than on
              exchanges or systems or in the over-the-counter market;

         o    in connection with short sales of the shares;

         o    by pledge to secure debt and other obligations;

         o    through the writing of options, whether the options are listed on
              an options exchange or otherwise;

         o    in connection with the writing of non-traded and exchange-traded
              call options, in hedge transactions and in settlement of other
              transactions in standardized or over-the-counter options; or

         o    through a combination of any of the above transactions.

         The selling stockholder and its successors, including its transferees,
pledgees or donees or their successors, may sell the common stock directly to
purchasers or through underwriters, broker-dealers or agents, who may receive
compensation in the form of discounts, concessions or commissions from the
selling stockholder or the purchasers. These discounts, concessions or
commissions as to any particular underwriter, broker-dealer or agent may be in
excess of those customary in the types of transactions involved.

         We have agreed to indemnify the selling stockholders, and each
director, officer or controlling person of each selling stockholder within the
meaning of Section 15 of the Securities Act of 1933 against all losses, claims,
damages, liabilities and expenses, (or action in respect thereof) including any
of the foregoing incurred in settlement of any litigation, commenced or
threatened, arising out of or based on (i) any untrue statement or alleged
untrue statement of a material fact contained in, or information incorporated by
reference into, any registration statement or prospectus (or any amendment or
supplement thereto) or any preliminary prospectus prepared in connection with
the registration contemplated by the Purchase Agreement, (ii) any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, (iii) any failure by
us to fulfill and perform any agreement, covenant or undertaking pursuant to the
Purchase Agreement, or (iv) any failure or breach of our representations and
warranties as set forth in the Purchase Agreement.

         The selling stockholders also may resell all or a portion of the shares
in open market transactions in reliance on Rule 144 under the Securities Act of
1933, if they meet the criteria and conform to the requirements of that rule.

                                       25


         The selling stockholders and any broker-dealers or agents that
participate with the selling stockholders in the sale of shares may be
"underwriters" within the meaning of the Securities Act of 1933. Any commissions
received by broker-dealers or agents on the sales and any profit on the resale
of shares purchased by broker-dealers or agents may be deemed to be underwriting
commissions or discounts under the Securities Act of 1933.

         Under the rules of the SEC, any person engaged in the distribution of
our common stock may not simultaneously buy, bid for or attempt to induce any
other person to buy or bid for our common stock in the open market for a period
of two business days prior to the beginning of the distribution. The rules and
regulations under the Securities Exchange Act of 1934 may also limit the timing
of purchases and sales of shares of our common stock by the selling
stockholders. We have notified the selling stockholders they should not begin
any distribution of common stock unless they have stopped purchasing and bidding
for common stock in the open market as provided in applicable securities
regulations, including Regulation M promulgated under the Securities Exchange
Act of 1934.

         We have informed the selling stockholders that the anti-manipulation
provisions of Regulation M may apply to the sales of their shares. We have
advised the selling stockholders of the requirement for delivery of this
prospectus in connection with any sale of the common stock.

           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

General

         We develop, manufacture and market microwave systems used in the
treatment of cancer. Our microwave systems are used in cancer treating therapies
that elevate the temperature of tumors or other targeted tissue to conditions
classified as either hyperthermia or thermal therapy (also called
thermotherapy), through precisely delivered microwave energy. We also own
approximately 30% of TherMatrx, Inc., a company engaged in the development and
marketing of a medical device designed to be used in the treatment of benign
prostatic hyperplasia. We supply thermotherapy systems, component parts and
contract manufacturing services to TherMatrx.

         Since our inception, we have been engaged in the development and
improvement of technology that can better accomplish cancer cure through
hyperthermia therapy. From our predecessor hyperthermia systems, our current
BSD-500 and BSD-2000 hyperthermia systems have emerged. We have also developed
enhancements to our BSD-2000 system including the BSD-2000/3D that is designed

                                       26


to allow three dimensional steering of deep focused energy and heat to targeted
tumors and tissue and the BSD-2000/3D/MR that includes an interface for magnetic
resonance imaging. Our hyperthermia systems are sold with supporting software
and may also be sold with support services. Since inception, we have generated
substantial operating losses and at August 31, 2003, had an accumulated deficit
of $20,486,107. We recorded net loss for fiscal 2003 of $570,285.

         We derived $1,907,585, or 74.14% of our revenue in fiscal 2003 from
sales to related parties. Approximately $1,391,443 of such related party revenue
was from manufacturing, assembling and testing thermotherapy systems for
TherMatrx and selling probes, applicators and temperature sensors and other
components and contract services to TherMatrx. We also realized $63,500 of
royalty revenue from TherMatrx, which is included in other revenue. The
remaining related party revenue of approximately $516,142 was for one BSD-2000
system and component parts sold to Medizin-Technik GmbH. Dr. Gerhard Sennewald,
one of our directors, is a stockholder, executive officer and a director of
Medizin-Technik GmbH.

         In fiscal 2003, we derived $326,597, or 12.69% of our revenue from
sales to unrelated parties. These revenues consisted of two BSD 500 systems for
$203,386, billable labor of $20,863, service contracts of $65,731, and sales of
consumable devices used with our hyperthermia systems of $36,617. We also
recognize revenue of $275,000 of royalties in arrears that were collected from a
legal settlement. Our ability to increase revenue depends primarily on our
ability to continue to provide hyperthermia or thermotherapy systems and
components to TherMatrx and Medizin-Technik and increase sales of our
hyperthermia systems domestically and internationally. We expect related party
revenues to continue to be a significant portion of total revenue as we continue
to sell hyperthermia systems in Europe through our distributor, Medizin-Technik.
We anticipate revenue from TherMatrx to be less in our second quarter of 2004,
and possibly the third quarter, than it was in the second and third quarter of
2003 because of TherMatrx's existing excess inventory. Consequently, we
currently expect revenue from TherMatrx to be less in fiscal 2004 than it was in
fiscal 2003. In fiscal 2004, we currently anticipate sales of our BSD-500 and
BSD-2000 systems to be a greater percentage of total revenue. We recorded a net
loss of $550,165 on revenue of $589,855 in the fourth quarter of fiscal 2003,
primarily due to a write-off of a significant receivable of approximately
$300,000.

         Cost of sales for the year ended August 31, 2003, included raw material
and labor costs. For the year ended August 31, 2003, we increased our reserve
for potential inventory impairment by $90,000, resulting in a total inventory
reserve of $140,000 at year-end. Because of the level of usage of certain
inventory items, we estimated that such items on hand potentially exceeded the
estimated near-term usage. Consequently, we determined to increase our inventory
reserve. Research and development expenses include expenditures for new product
development and development of enhancements to existing products.

Critical Accounting Policies and Estimates

         The following is a discussion of our critical accounting policies and
estimates that management believes are material to an understanding of our
results of operations and which involve the exercise of judgment or estimates by
management.

         Revenue Recognition. Revenue is recognized when a valid purchase order
has been received, services have been performed or product has been delivered,
the selling price is fixed or determinable, and collectibility is reasonably
assured. Sales include revenue from systems with software products, software
license rights and service contracts. Software Revenue Recognition, generally
requires revenue earned on software arrangements involving multiple elements
such as software products, enhancements, post-contract customer support,
installation and training to be allocated to each element based on the relative
fair values of the elements. The revenue allocated to software products is

                                       27


generally recognized upon delivery of the products. The revenue allocated to
post-contract customer support is generally recognized over the support period.
Revenue for products sold is recorded when products are delivered. Revenue from
long-term service contracts is recognized on a straight-line basis over the term
of the contract, which approximates recognizing it as it is earned. Deferred
revenue and customer deposits payable includes amounts from service contracts as
well as revenue from sales of products, which have not been shipped. We estimate
collectibility of receivables based on numerous factors, including the credit
worthiness of the customer, prior payment history, and review of public
information.

         Inventory Reserves. As of August 31, 2003, we had recorded a reserve
for potential inventory impairment of $140,000. Due to the level of usage of
certain inventory items, we estimated that such items on hand potentially
exceeded the estimated near-term usage. As a result, we determined to increase
the inventory reserve by $90,000 in the fourth quarter. This estimate is
determined based on our forecasted sales and related inventory usage to fill
such sales orders as well as evaluation of technological enhancements that may
render inventory items obsolete in the near-term. We periodically review our
inventory levels and usage, paying particular attention to slower-moving items.
If projected sales for fiscal 2004 do not materialize or if our hyperthermia
systems do not receive increased market acceptance, we may be required to
increase the reserve for inventory in future periods.

         Product Warranty. We provide product warranties on our BSD-500 and
BSD-2000 systems. These warranties vary from contract to contract, but generally
consist of parts and labor warranties for one year from the date of sale. To
date, expenses resulting from such warranties have not been material. We record
a warranty expense at the time of each sale. This reserve is estimated based on
prior history of service expense associated with similar units sold in the past.

         Allowance for Doubtful Accounts. We provide our customers with payment
terms that vary from contract to contract. We perform ongoing credit evaluations
of our customers and maintain allowances for possible losses which, when
realized, have been within the range of management's expectations with exception
of the bad debt expense of approximately $300,000 recorded fiscal 2003 as
discussed below. Our allowance for doubtful accounts at August 31, 2003 was
approximately $67,000, or approximately 14.23% of the total outstanding
receivables. Bad debt expense for the fiscal year ended August 31, 2003 was
approximately $300,000. This resulted from a sale of BSD-2000 that was recorded
in FYE 2002 to customer that was determined to be uncollectible in the fourth
quarter of 2003. Allowance estimates are recorded on a customer-by-customer
basis and are determined based on the age of the receivable, compliance with
payment terms, and prior history with existing clients. To date, actual results
have not differed materially from management's estimates, with the exception of
the above-mentioned bad debt. The non-payment of a receivable related to the
sale of a BSD-500 or BSD-2000 could have a material adverse impact on our
results of operations.

Results of Operations

Three months Ended November 30, 2003 Compared to Three Months Ended November 30,
2002

         Sales decreased from $800,285 in the three months ended November 30,
2002, to $681,134 in the three months ended November 30, 2003, a decrease of
$119,151 or 14.89%, primarily due to a decrease in sales to the Company's
unconsolidated subsidiary. The decrease was due to a significant drop in sales
to TherMatrx, due to TherMatrx's existing excess inventory. We derived $20,592,
or 3.02% of total revenue in the period ended November 30, 2003 from
manufacturing, assembling and testing thermotherapy systems for TherMatrx and
selling probes, applicators and temperature sensors and other components and
contract services to TherMatrx. The remaining related party revenue of $466,633,
or 68.5% was for one BSD-2000 system and component parts sold to Medizin-Technik

                                       28


GmbH. Dr. Gerhard Sennewald, one of our directors, is a stockholder, executive
officer and a director of Medizin-Technik GmbH. The remaining revenue was
$143,300 for the sale of a BSD-500, $26,722 for service contracts, $6,050 for
billable labor and $17,837 for miscellaneous items.

         Gross profit for the period ending November 30, 2003 was $351,004 or
51.53% as compared to $451,127 or 56.37% of total product sales for the period
ending November 30, 2002. This decrease was primarily due to a change in product
mix.

         Selling, general and administrative expenses decreased to $212,575 in
the three months ended November 30, 2003, from $248,991 in the three months
ended November 30, 2002 a decrease of $36,416 or 14.63%. This decrease was
primarily due to lower legal and consulting costs. Total costs and expenses
decreased by $48,545, a decrease of 6.44%, primarily due to decreased cost of
goods sold as a result of decreased sales and the aforementioned decrease in
selling, general and administrative expense offset by increases in research and
development.

         Research and development expenses were $162,558 for the three months
ended November 30, 2003, as compared to $155,659 in the three months ended
November 30, 2002. Research and development expenses in the period ending
November 30, 2003 related primarily to development work on our BSD-2000/3D/MR
hyperthermia system and enhancements to our BSD-500 systems.

         The net loss for the three months ending November 30, 2003, was $24,136
as compared with net income of $47,606 for the three months ending November 30,
2002 was primarily due to lower sales volume.

Fiscal Year Ended August 31, 2003 Compared to Fiscal Year Ended August 31, 2002

         Revenue. Revenue for fiscal 2003 was $2,572,682 compared to $2,672,472
for fiscal 2002, a decrease of $99,790, or approximately 3.73%. This decrease
was mainly due to a decrease in sales to TherMatrx. Product sales decreased to
$2,234,182 in 2003 from $2,672,472 in 2002 a decrease of $438,290 or 16.4%.

         Related Party Revenue. We derived $1,907,585, or 74.14% of our revenue
in fiscal 2003 from sales to related parties as compared to $1,854,714, or 69.4%
in fiscal 2002. Approximately $1,391,443 of such related party revenue in fiscal
2003 was from the sales of thermotherapy systems, component products and
contract services to TherMatrx. There was also a payment for royalty revenue of
$63,500 paid to us by Thermatrx that is included in other revenue. During fiscal
2002, sales to TherMatrx were approximately $1,781,000. The remaining related
party revenue of approximately $516,142 in fiscal 2003 was for one BSD-2000
system and various component parts sold to Medizin-Technik. Dr. Gerhard
Sennewald, one of our directors and stockholders, is a stockholder, executive
officer and a director of Medizin-Technik. During fiscal 2002, we had sales of
approximately $74,000 to Medizin-Technik. The significant increase in sales to
Medizin-Technik in fiscal 2003 was due to the normal rise and fall cycle
associated with the sale of large-ticket item capital equipment.

         Non-related Party Revenue. In fiscal 2003, we derived approximately
$601,597, or 23.38% of our total revenue as compared to approximately $817,758,
or 30.59% in fiscal 2002 through non-related party sales. Our non-related party
revenue consisted of sales of two BSD-500 systems in fiscal 2003 for
approximately $203,386, consumable devices of $36,617, billable labor of
$20,863, service contracts of $65,731 and royalty revenue of $275,000.

                                       29


         Cost of Sales. Cost of sales for fiscal 2003 was $1,227,377 compared to
$1,114,846 for fiscal 2002, an increase of $112,531, or approximately 10.09%.
This increase resulted primarily from charges to cost of sales for obsolete
inventory of $90,000 Cost of sales for fiscal 2003 to unrelated parties
decreased to $94,619 from $302,431 primarily because of the decrease in sales to
unrelated customers. Cost of sales to related parties in fiscal 2003 increased
to $1,132,758 from $812,415 in fiscal 2002 primarily because of the change in
product mix and an increase in related party sales. During fiscal 2003,
approximately 74% of the related party cost of sales were to TherMatrx and 26%
were to Medizin-Technik. The products sold to TherMatrx generally require less
cost per unit to manufacture than the BSD-2000 and BSD-500 systems.

         Gross Profit. Gross profit for fiscal 2003 was $1,070,305 or 47.9% of
total product sales and related service, excluding royalty revenue in arrears,
compared to $1,557,626, or 58.28% of total product sales in fiscal 2002. The
decrease in gross profit as a percentage of total product sales was primarily
because of decreases in sales of higher margin hyperthermia system products in
fiscal 2003.

         Research and Development Expenses. Research and development expenses
for fiscal 2003 were $676,867 compared to $603,137 for fiscal 2002, an increase
of $73,730, or 12.22%. Research and development expenses in fiscal 2003 related
primarily to development of commercial version of BSD-2000/3D/MR hyperthermia
system and to our BSD-500 systems.

         Inventory Impairment Expense. We recorded an inventory impairment
charge in fiscal 2003 of $90,000 increasing our total inventory reserve at
August 31, 2003 to $140,000.

         Selling, General and Administrative Expenses. Selling, general and
administrative expenses for fiscal 2003 were $1,241,561 compared to $1,667,042
in fiscal 2002, a decrease of $425,481, or approximately 25.52%. This decrease
was primarily due to less compensation expense of $717,000 related to the
issuance of options to purchase TherMatrx stock in fiscal 2002. This was offset
by higher bad debt expense of $300,394 and increased legal fees and lower
administrative and regulatory costs and special promotion costs.

         Other Income. Other income for fiscal 2003 was $2,838 compared to
$722,198 in fiscal 2002, a decrease of $719,360. This decrease resulted almost
entirely from a gain recognized in 2002 on transfer of equity interest in
affiliate to related parties as noted above.

         Net Loss. In fiscal 2003 we had a net loss of $570,285 as compared to
net income in fiscal of $9,645. The net loss was primarily caused by an increase
in bad debt expense of $300,394, an increase in inventory reserve of $90,000 and
lower overall sales for fiscal 2003.

         Fluctuation in Operating Results. Our results of operations have
fluctuated in the past and may fluctuate in the future from year to year as well
as from quarter to quarter. Revenue may fluctuate as a result of factors
relating to the operating success of TherMatrx and its continued demand for
thermotherapy systems and component parts supplied by us, market acceptance of
our BSD hyperthermia systems, changes in the medical capital equipment market,
changes in order mix and product order configurations, competition, regulatory
developments and other matters. Operating expenses may fluctuate as a result of
the timing of sales and marketing activities, research and development and
clinical trial expenses, and general and administrative expenses associated with
our potential growth. For these and other reasons, including those set forth in
"Risks of our Business" in Part I, our results of operations for a particular
period may not be indicative of operating results for any other period.

                                       30


Liquidity and Capital Resources

         Since inception, we have generated an accumulated deficit of
$20,510,243 at November 30, 2003. We have historically financed our operations
through cash from operations, licensing of technological assets and issuance of
common stock.

         We used $227,298 in cash from operating activities in fiscal 2003
compared to cash generated of $19,800 in fiscal 2002. This was a result of a
significant uncollectible receivable of $300,000 that contributed to a net loss
of $570,285 for fiscal 2003 compared to net income of $9,645 in 2002, and a
reduction of accounts receivable of $9,614 as compared to $55,173 in fiscal 2002
offset by an increase in accounts payable of $217,447 compared to a reduction in
accounts payable of $51,121 in fiscal 2002. Accrued expenses decreased by
$133,066 primarily as a result of a decrease in customer deposits as orders were
shipped. Our investing activities resulted in net cash used of $60,599 relating
to the purchase of certain property and equipment. Cash provided by financing
activities totaled $2,000 reflecting proceeds from the issuance of common stock
in connection with the exercise of outstanding stock options.

         We used $86,827 in cash from operating activities during the period
ended November 30, 2003 compared to cash generated of $99,428 in the period
ending November 30, 2002. Cash flow from operating activities decreased in the
November 30, 2003 period primarily because of lower sales volume compared to the
prior year period.

         On November 28, 2003, we completed the sale of an aggregate of
1,820,000 shares of our common stock to investors for cash consideration of
$1.10 per share, or a total of $2,002,000. The net proceeds from the
transaction, after paying a commission to our placement agent, T.R. Winston &
Company, LLC, and legal other expenses related to the transaction, were
approximately $1,836,000.

         At November 30, 2003, our working capital was $2,281,196 and our cash
and cash equivalents totaled $2,051,376. We have no bank debt and no credit
facility. Our contractual obligations and commercial commitments requiring
capital resources include building rent of $82,000 per year for five years
adjusted annually for increases in the cost of living based on the Consumer
Price Index for Urban Consumers.

         On December 10, 2003 there was an additional 239,600 shares issued to
investors at $1.10 per share or a total of $263,560.

         Our ability to fund our cash needs and grow our business depends on our
ability to generate cash flow from operations and capital from financing
activities. Our operating cash flow has fluctuated significantly in the past and
may continue to do so in the future. We believe that our current working capital
and anticipated cash flow from future operations will be sufficient to fund our
anticipated operations for fiscal 2004. We have based this belief, however, on
assumptions that may prove to be wrong. We expect our revenue from sales of
products to TherMatrx to decline in the second quarter, and possibly the third
quarter, of 2003 compared to the second and third quarters of 2002. We also
expect to incur additional expenses related to the commercial introduction of
our BSD-500 systems, which will precede any revenue from the sale of such
systems. We believe any cash shortfall during fiscal 2004 that results from this
decrease in revenues and increase in expenses can be covered through the cash
raised in our November and December 2003 private placements. However, if our
revenues from TherMatrx decrease more or more rapidly than we currently expect
or revenues from the sale of our systems is lower than we currently expect, we
will have to cut expenses or use more of our available cash than we anticipated.
If we cannot cover any such cash shortfall with cost cutting or available cash,
we would need to obtain additional financing. We cannot be certain that any
financing will be available when needed or will be available on terms acceptable
to us. Insufficient funds may require us to delay, scale back or eliminate some
or all of our programs designed to facilitate the commercial introduction of our
systems.

                            DESCRIPTION OF SECURITIES

General

         We are authorized to issue 40,000,000 shares of common stock, $0.001
par value, and 10,000,000 shares of undesignated preferred stock, $0.001 par
value per share.

         The following description of our capital stock is a summary, it is not
complete and is subject to and qualified in its entirety by our Amended and
Restated Certificate of Incorporation and Bylaws, a copy of each of which has
been incorporated as an exhibit to the registration statement of which this
prospectus forms a part, and the provisions of applicable Delaware law.

         Our Amended and Restated Certificate of Incorporation and Bylaws
contain certain provisions that are intended to enhance the likelihood of
continuity and stability in the composition of the board of directors, which may
have the effect of delaying, deferring or preventing a future takeover or change
in control of BSD unless such takeover or change in control is approved by our
board of directors.

                                       34


Common Stock

         As of January 23, 2004, there were 19,915,232 shares of common stock
outstanding, which were held of record by 595 stockholders.

         Holders of common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Holders of common stock do not
have cumulative voting rights, and, therefore, holders of a majority of the
shares voting for the election of directors can elect all of the directors. In
such event, the holders of the remaining shares will not be able to elect any
directors. Subject to preferences that may be applicable to any then-outstanding
preferred stock, holders of common stock are entitled to receive such dividends
as may be declared from time to time by our board of directors out of funds
legally available therefore. We have never declared or paid cash dividends on
our capital stock, expect to retain future earnings, if any, for use in the
operation and expansion of its business, and do not anticipate paying any cash
dividends in the foreseeable future.

         In the event of liquidation, dissolution or winding up of BSD, holders
of common stock are entitled to share ratably in all assets legally available
for distribution after payment of all debts and other liabilities and subject to
the prior rights of the holders of any preferred stock then outstanding. Holders
of common stock have no preemptive or other subscription or conversion rights,
and there are no redemption or sinking fund provisions applicable to the common
stock.

Preferred Stock

         As of January 23, 2004, there were no shares of preferred stock
outstanding. Our Amended and Restated Certificate of Incorporation authorize
10,000,000 shares of undesignated preferred stock. Our board of directors will
have the authority, without any further vote or action by our stockholders, to
issue from time to time the preferred stock in one or more series and to fix the
price, rights, preferences, privileges and restrictions thereof, including
dividend rights, dividend rates, conversion rights, voting rights, terms of
redemption, redemption prices, liquidation preferences and the number of shares
constituting a series or the designation of such series. The issuance of
preferred stock, while providing desirable flexibility in connection with
possible acquisitions and other corporate purposes, could decrease the amount of
earnings and assets available for distribution to holders of common stock or
adversely affect the rights and powers, including voting rights, of the holders
of common stock, and may have the effect of delaying, deferring or preventing a
change in control of BSD without further action by the stockholders. We have no
current plans to issue any shares of preferred stock.

Warrants and Options

         As of January 23, 2004 warrants to purchase an aggregate of 102,980
shares of our common stock at a weighted average exercise price per share of
$1.80 were issued and outstanding and options to purchase an aggregate 1,112,300
shares of our common stock at a weighted average exercise price per share of
$0.49 were issued and outstanding.

Antitakeover Effects of Provisions of Our Amended and Restated Certificate of
Incorporation and Bylaws and Delaware Law

         Certain provisions of our Amended and Restated Certificate of
Incorporation and Bylaws could make the following more difficult:

                                       35


         o    acquisition of BSD by means of a tender offer;

         o    acquisition of BSD by means of a proxy contest or otherwise; and

         o    the removal of our incumbent officers and directors.

         These provisions, summarized below, are expected to discourage coercive
takeover practices and inadequate takeover bids. These provisions are also
designed to encourage persons seeking to acquire control of BSD to first
negotiate with our board of directors. We believe that the benefits of increased
protection resulting from our potential ability to negotiate with the proponent
of an unfriendly or unsolicited proposal to acquire or restructure BSD outweigh
the disadvantages of discouraging such proposals because we believe that the
negotiation of such proposals could result in an improvement of their terms.

         Stockholder Meetings. Our Amended and Restated Certificate of
Incorporation provide that only the board of directors, the Chairman of the
board, the Chief Executive Officer or the President of BSD may call special
meetings of stockholders. The provision may not be amended without the
affirmative vote of holders of at least 66 2/3% of the outstanding voting stock
of BSD.

         Elimination of Stockholder Action By Written Consent. Our charter
documents eliminate the right of stockholders to act by written consent without
a meeting.

         Elimination of Cumulative Voting. Our charter documents do not provide
for cumulative voting in the election of directors.

         Undesignated Preferred Stock. The ability to authorize undesignated
preferred stock makes it possible for the Board of Directors to issue preferred
stock with voting or other rights or preferences that could impede the success
of any attempt to change control of BSD. These and other provisions may have the
effect of deferring hostile takeovers or delaying changes in control or
management of BSD.

         The provisions of Delaware law and our Amended and Restated Certificate
of Incorporation and Bylaw could have the effect of discouraging others from
attempting unsolicited takeovers and, as a consequence, they may also inhibit
temporary fluctuations in the market price of our common stock that often result
from actual or rumored unsolicited takeover attempts. Such provisions may also
have the effect of preventing changes in our management. It is possible that
these provisions could make it more difficult to accomplish transactions, which
stockholders may otherwise deem to be in their best interests.

                   LIMITATION OF LIABILITY AND INDEMNIFICATION

         Section 145 of the Delaware General Corporation Law permits a
corporation to include in its charter documents, and in agreements between the
corporation and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by the current law.

         Article 8 of our Amended and Restated Certificate of Incorporation
provides for the indemnification of directors to the fullest extent permissible
under Delaware law.

         Section 8 of our Bylaws provides for the indemnification of officers,
directors and third parties acting on behalf of BSD if such person acted in good
faith and in a manner reasonably believed to be in and not opposed to the best
interest of BSD, and, with respect to any criminal action or proceeding, the
indemnified party had no reason to believe his or her conduct was unlawful.

                                       36


         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to our directors, officers and controlling persons
pursuant to the foregoing provisions, or otherwise, we have been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.

                                  LEGAL MATTERS

         The validity under the Delaware General Corporation Law of the common
stock to be sold by the selling stockholders has been passed on for us by Dorsey
& Whitney LLP, Salt Lake City, Utah.

To the Board of Directors and Stockholders
of BSD Medical Corporation


We have audited the balance sheet of BSD Medical Corporation (the Company) as of
August 31, 2003, and the related statements of operations, stockholders' equity,
and cash flows for the years  ended  August 31, 2003 and 2002.  These  financial
statements   are  the   responsibility   of  the   Company's   management.   Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the  United  States of  America.  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 BSD Medical  Corporation as of
August 31, 2003,  and the results of its operations and cash flows for the years
ended  August  31,  2003  and  2002 in  conformity  with  accounting  principles
generally accepted in the United States of America.

1.   Organization       Property and Equipment
     of Significant     Property   and   equipment   are  stated  at  cost  less
     Accounting         accumulated depreciation.  Depreciation and amortization
     Policies           are determined using the  straight-line  method over the
     Continued          estimated  useful lives of the assets.  Expenditures for
                        maintenance  and repairs are expensed  when incurred and
                        betterments are  capitalized.  Gains and losses on sales
                        of property and equipment are reflected in operations.

                        Investment in Joint Venture
                        The  Company  has  an   approximate   30%  ownership  in
                        TherMatrx,  a corporate joint venture that is engaged in
                        the  manufacture  and  sale  of  medical  devices.   The
                        investment  is  accounted  for on the  equity  method of
                        accounting.  Because  the  Company's  percent  share  of
                        accumulated   losses  in  TherMatrx   has  exceeded  its
                        original  investment no asset is recorded on the balance
                        sheet.  The Company has included in accrued  liabilities
                        $136,467 of potential obligations to TherMatrx, which it
                        incurred in a prior year.  No further  obligations  have
                        been  recognized  as the Company has not  guaranteed  or
                        otherwise   committed  to  provide   further   financial
                        funding.

                        Patents
                        Patents are carried at cost and are being amortized over
                        17 years.

                        Income Taxes
                        The Company  accounts  for income  taxes using the asset
                        and  liability  method.  Under the  asset and  liability
                        method,   deferred  tax  assets  and   liabilities   are
                        recognized for the future tax consequences  attributable
                        to differences  between the financial statement carrying
                        amounts of  existing  assets and  liabilities  and their
                        respective   tax   bases.   Deferred   tax   assets  and
                        liabilities   are  measured   using  enacted  tax  rates
                        expected  to apply to  taxable  income  in the  years in
                        which those  temporary  differences  are  expected to be
                        recovered or settled.  The effect on deferred tax assets
                        and  liabilities  of a change in tax rates is recognized
                        in income in the  period  that  includes  the  enactment
                        date.

                        Income (Loss) Per Common Share
                        The  computation of basic income (loss) per common share
                        is  based  on the  weighted  average  number  of  shares
                        outstanding during each year.

                                                                             F-7

1.   Organization       Income (Loss) Per Common Share - Continued
     of Significant     The computation of diluted  earnings per common share is
     Accounting         based  on  the   weighted   average   number  of  shares
     Policies           outstanding  during  the  year,  plus the  common  stock
     Continued          equivalents  that would arise from the exercise of stock
                        options and  warrants  outstanding,  using the  treasury
                        stock  method  and the  average  market  price per share
                        during  the  year.  Common  stock  equivalents  are  not
                        included in the diluted loss per share  calculation when
                        their  effect  is  anti-dilutive.  Options  to  purchase
                        1,275,303 shares and 1,258,901 shares of common stock at
                        prices  ranging  from  $.10  to  $1.76  per  share  were
                        outstanding  at August 31, 2003 and 2002,  respectively.
                        Options  outstanding during the fiscal year ended August
                        31, 2003 were not included in the calculation of diluted
                        earnings   per   share    because   their   effect   was
                        anti-dilutive.

                        been  received,  services have been performed or product
                        has  been  delivered,  the  selling  price  is  fixed or
                        determinable, and collectibility is reasonably assured.

                        Sales   include   revenue  from  systems  with  software
                        products, software license rights and service contracts.
                        Software revenue recognition, generally requires revenue
                        earned  on  software  arrangements   involving  multiple

                        relative  fair  values  of  the  elements.  The  revenue
                        allocated to software  products is generally  recognized
                        upon delivery of the products.  The revenue allocated to
                        post-contract  customer support is generally  recognized
                        over the support period. Sales for products are recorded
                        when  products are  delivered.  Revenue  from  long-term
                        service contracts is recognized on a straight-line basis
                        over  the  term  of  the  contract,  which  approximates
                        recognizing  it as it is earned.  Deferred  revenue  and
                        customer  deposits  payable include amounts from service
                        contracts  as well as revenue  from  sales of  products,
                        which have not been shipped.

7.   Stock              Stock Options
     Options and        The Company's 1987 Employee Stock Option Plan authorizes
     Warrants           the  granting  of  incentive   options  to  certain  key
                        employees of the Company and nonqualified  stock options
                        to certain key  employees,  non-employee  directors,  or
                        individuals  who provide  services to the  Company.  The
                        Plan,  as amended,  provides for the granting of options
                        for an  aggregate  of 950,000  shares.  The options vest
                        according to a set schedule over a five-year  period and
                        expire  upon the  employee's  termination  or after  ten
                        years from the date of grant.

                        The Company's 1998 Employee Stock Option Plan authorizes
                        the granting of incentive  stock  options to certain key
                        employees and  non-employees who provide services to the
                        Company.  The Plan  provides for the granting of options
                        for an aggregate of 2,000,000  shares.  The options vest
                        subject to management's discretion.

                        The  Company's  1998 Director  Stock Plan  authorizes an
                        annual  compensation  of  $12,000  to each  non-employee
                        director.  The annual  compensation  may be satisfied by
                        issuing  common stock,  with the number of shares issued
                        calculated  by  dividing  the unpaid  compensation  by a
                        daily average of the preceding  twenty day closing price
                        of the Company's common stock. The Plan also grants each
                        non-employee  outside  director 25,000 options each year
                        at an exercise  price of 85% of the fair market value of
                        the common stock at the date the option is granted.  The
                        Plan allows for an aggregate  of 1,000,000  shares to be
                        granted.  The options  vest  according to a set schedule
                        over a five-year  period and expire upon the  director's
                        termination,  or after ten years from the date of grant.
                        For certain  options issued under this plan, the Company
                        has recorded as deferred  compensation the excess of the
                        market  value of common  stock at the date of grant over
                        the exercise price.

                        are not  necessarily  indicative of the amounts that the
                        Company could realize in a current market exchange.

14.  Recent             In April 2002, the FASB issued SFAS No. 145,  Rescission
     Accounting         of SFAS Nos.  4, 44, and 64,  Amendment  of SFAS 13, and
     Pronounce-         Technical  Corrections as of April 2002 (SFAS 145). This
     ments              standard rescinds SFAS No. 4, Reporting Gains and Losses
                        from  extinguishment  of Debt,  and an amendment of that
                        Statement,  SFAS No. 64, Extinguishments of Debt Made to
                        Satisfy    Sinking-Fund    Requirements   and   excludes
                        extraordinary   item  treatment  for  gains  and  losses
                        associated with the  extinguishment  of debt that do not
                        meet the APB  Opinion No. 30,  Reporting  the Results of
                        Operations  --  Reporting  the  Effects of Disposal of a

                        that was  classified as an  extraordinary  item in prior
                        periods presented that does not meet the criteria in APB
                        30 for  classification as an extraordinary item shall be
                        reclassified.  SFAS 145 also amends SFAS 13,  Accounting
                        for  Leases  as well  as  other  existing  authoritative
                        pronouncements  to make various  technical  corrections,
                        clarify meanings,  or describe their applicability under
                        changed  conditions.  Certain  provisions  of  SFAS  are
                        effective for transactions  occurring after May 15, 2002
                        while others are  effective  for fiscal years  beginning
                        after May 15, 2002.  The adoption of SFAS No. 145 by the
                        Company did not have a material  impact on the Company's
                        financial position or operations.

14.  Recent             In June 2002,  the FASB issued SFAS No. 146,  Accounting
     Accounting         for Costs  Associated  with Exit or Disposal  Activities
     Pronounce-         (SFAS 146). This standard addresses financial accounting
     ments              and reporting for costs associated with exit or disposal
     Continued          activities and replaces Emerging Issues Task Force Issue
                        No. 94-3,  Liability  Recognition  for Certain  Employee
                        Termination Benefits and Other Costs to Exit an Activity
                        (including  Certain Costs  Incurred in a  Restructuring)
                        (EITF  94-3).  SFAS 146  requires  that a liability  for
                        costs  associated  with an exit or disposal  activity be
                        recognized  when the  liability is incurred.  Under EITF
                        94-3, a liability for exit costs, as defined in EITF No.
                        94-3  were   recognized  at  the  date  of  an  entity's
                        commitment to an exit plan.  The  provisions of SFAS 146
                        are effective for exit or disposal  activities  that are
                        initiated by the Company  after  December 31, 2002.  The
                        adoption  of SFAS No. 146 by the  Company did not have a
                        material impact on the Company's  financial  position or
                        operations.

                        In  December   2002,   the  FASB  issued  SFAS  No.  148
                        "Accounting for Stock-Based Compensation--Transition and
                        Disclosure--an  amendment  of FASB  Statement  No. 123,"
                        which is  effective  for all fiscal  years  ending after
                        December  15, 2002.  SFAS No. 148  provides  alternative
                        methods of transition for a voluntary change to the fair
                        value  based  method  of  accounting   for   stock-based
                        employee  compensation  under  SFAS  No.  123  from  the
                        intrinsic value based method of accounting prescribed by
                        Accounting  Principles  Board  Opinion  No. 25. SFAS 148
                        also changes the  disclosure  requirements  of SFAS 123,
                        requiring a more  prominent  disclosure of the pro-forma
                        effect of the fair value based method of accounting  for
                        stock-based  compensation.  The adoption of SFAS No. 148
                        by the  Company  did not have a  material  impact on the
                        Company's financial position or operations.

14.  Recent             In January 2003, the FASB issued  Interpretation No. 46,
     Accounting         "Consolidation  of Variable  Interest  Ethics"  (FIN No.
     Pronounce-         46),   which   addresses   consolidation   by   business
     ments              enterprises of variable  interest  entities.  FIN No. 46
     Continued          clarifies  the   application   of  Accounting   Research
                        Bulletin No. 51, "Consolidated Financial Statements", to
                        certain  entities in which equity  investors do not have
                        the characteristics of a controlling  financial interest
                        or do not have sufficient  equity at risk for the entity
                        to   finance   its   activities    without    additional
                        subordinated  financial support from other parties.  FIN
                        No. 46 applies immediately to variable interest entities
                        created after January 31, 2003, and to variable interest
                        entities  in which an  enterprise  obtains  an  interest
                        after that date.  It applies in the first fiscal year or
                        interim  period   beginning  after  June  15,  2003,  to
                        variable  interest entities in which an enterprise holds
                        a variable  interest that it acquired before February 1,
                        2003.  The  Company  does not  expect  to  identify  any
                        variable interest entities that must be consolidated. In
                        the event a variable interest entity is identified,  the
                        Company does not expect the  requirements  of FIN No. 46
                        to have a material impact on its financial  condition or
                        results of operations.

                        In November 2002, the FASB issued Interpretation No. 45,
                        "Guarantor's  Accounting and Disclosure Requirements for
                        Guarantees,    Including    Indirect    Guarantees    of
                        Indebtedness  of  Others"  (FIN  No.  45).  FIN  No.  45
                        requires  certain  guarantees  to be  recorded  at  fair
                        value,  which is  different  from  current  practice  to
                        record a  liability  only  when a loss is  probable  and
                        reasonably estimable, as those terms are defined in FASB
                        Statement No. 5, "Accounting for Contingencies". FIN No.
                        45 also  requires  the Company to make  significant  new
                        disclosures    about    guarantees.    The    disclosure
                        requirements of FIN No. 45 are effective for the Company
                        in the first  quarter of fiscal year 2003.  FIN No. 45's
                        initial recognition and initial  measurement  provisions
                        are  applicable  on a  prospective  basis to  guarantees
                        issued or modified after December 31, 2002. The adoption
                        of FIN No.  45 did not  have a  material  impact  on the
                        Company's financial  position,  results of operations or
                        cash flows.

14.  Recent             In April 2003, the FASB issued SFAS No. 149,  "Amendment
     Accounting         of Statement 133 on Derivative  Instruments  and Hedging
     Pronounce-         Activities." SFAS No. 149 amends and clarifies financial
     ments              accounting  and  reporting for  derivative  instruments,
     Continued          including  certain  derivative  instruments  embedded in
                        other   contracts    (collectively    referred   to   as
                        derivatives)  and for hedging  activities under SFAS No.
                        133, "Accounting for Derivative  Instruments and Hedging
                        Activities".  This  Statement is effective for contracts
                        entered  into or  modified  after  June 30,  2003,  with
                        certain  exceptions,   and  for  hedging   relationships
                        designated after June 30, 2003, with certain exceptions,
                        and for hedging relationships  designated after June 30,
                        2003. Management is currently evaluating the effect that
                        the  adoption of SFAS No. 149 may have,  but believes it
                        will  not  have a  material  effect  on its  results  of
                        operations and financial position.

                        In May 2003,  the FASB issued SFAS No. 150,  "Accounting
                        for Certain Financial  Instruments with  Characteristics
                        of both  Liabilities  and  Equity."  This new  statement
                        changes the accounting for certain financial instruments
                        that, under previous guidance, issuers could account for
                        as equity or  classifications  between  liabilities  and
                        equity in a section  that has been  known as  "mezzanine
                        capital." It requires that those certain  instruments be
                        classified as liabilities in balance sheets. Most of the
                        guidance  in SFAS  150 is  effective  for all  financial
                        instruments entered into or modified after May 31, 2003.
                        Management anticipates that the adoption of SFAS No. 150
                        may have a material impact on the Company's consolidated
                        financial statements if in the future the Company issues
                        mandatorily redeemable preferred stock. Such mandatorily
                        redeemable  preferred  stock,   previously  included  as
                        "mezzanine capital", would be included as a liability in
                        accordance with SFAS 150.

15.  Subsequent         On November 28, 2003, the Company  completed the sale of
     Event              an  aggregate  of  1,820,000  shares of common  stock to
                        three  institutional  investors.  The  shares  of common
                        stock  were  sold for cash  consideration  of $1.10  per
                        share,  or a total of $2,002,000,  pursuant to the terms
                        of the Securities Purchase Agreement entered into by and
                        among the  investors  and the Company as of November 28,
                        2003.  These  shares were issued in a private  placement
                        transaction  pursuant to Section  4(2) and  Regulation D
                        under  the  Securities  Act  of  1933,  as  amended.  As
                        provided  in  the  Securities  Purchase  Agreement,  the
                        Company  also  agreed  to  cause  a  shelf  registration
                        statement  covering  the  resale  of these  shares to be
                        filed no later  than 60 days  after the  closing  of the
                        private  placement.  The Company  estimates that the net
                        proceeds from the transaction, after paying a commission
                        to the placement agent, T.R. Winston & Company, LLC, and
                        legal other expenses related to the transaction, will be
                        approximately $1,840,000. The Company has also agreed to
                        issue to the  placement  agent a  three-year  warrant to
                        purchase up to 91,000  shares at an  exercise  price per
                        share of $1.80 as  provided in the  Securities  Purchase
                        Agreement.

                        On December 10, 2003 the Company sold 239,600  shares of
                        common  stock at $1.10 per share or a total of $263,560.
                        The Company  issued to the placement  agent a three-year
                        warrant to purchase  up to 11,980  shares at an exercise
                        price of $1.80.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 24. Indemnification of Directors and Officers.

         Section 145 of the Delaware General Corporation Law permits a
corporation to include in its charter documents, and in agreements between the
corporation and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by the current law.

         Article 8 of our Amended and Restated Certificate of Incorporation
provides for the indemnification of directors to the fullest extent permissible
under Delaware law.

         Section 8 of our Bylaws provides for the indemnification of officers,
directors and third parties acting on behalf of BSD if such person acted in good
faith and in a manner reasonably believed to be in and not opposed to the best
interest of BSD, and, with respect to any criminal action or proceeding, the
indemnified party had no reason to believe his or her conduct was unlawful.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to our directors, officers and controlling persons
pursuant to the foregoing provisions, or otherwise, we have been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.

ITEM 25. Other Expenses of Issuance and Distribution.

         The following table sets forth the various costs and expenses to be
paid by us with respect to the sale and distribution of the securities being
registered. All of the amounts shown are estimates except for the SEC
registration fee.

SEC Registration Fee....................................        $342.50

Legal Fees and Expenses.................................     $50,000.00

Accounting Fees and Expenses............................      $5,000.00

Printing and Other Expenses.............................      $2,500.00
                                                             ----------

     Total..............................................     $57,842.50
                                                             ----------

         We will bear all costs, expenses and fees in connection with the
registration of the shares. The selling stockholders will bear all commissions
and discounts, if any, attributable to the sales of the shares.

ITEM 28. Undertakings.

         The undersigned Registrant hereby undertakes:

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

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

              (ii) To reflect in the prospectus any facts or events arising
         after the effective date of this registration statement (or the most
         recent post-effective amendment hereof) which, individually or in the
         aggregate, represent a fundamental change in the information set forth
         in this registration statement. Notwithstanding the foregoing, any
         increase or decrease in volume of securities offered (if the total
         dollar value of securities offered would not exceed that which was
         registered) and any deviation from the low or high end of the estimated
         maximum offering price may be reflected in the form of prospectus filed
         with the SEC under Rule 424(b) if, in the aggregate, the changes in
         volume and price represent no more than a 20 percent change in the
         maximum aggregate offering price set forth in the "Calculation of
         Registration Fee" table in the effective registration statement; and


                                     III-3




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

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

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered that remain unsold at the termination of
the offering.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of BSD
Medical Corporation pursuant to the foregoing provisions, or otherwise, BSD
Medical Corporation has been advised that in the opinion of the SEC 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 BSD Medical Corporation of
expenses incurred or paid by a director, officer or controlling person of BSD
Medical Corporation 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, BSD Medical Corporation will,
unless in the opinion of its counsel the question has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
