                               PROSPECTUS SUMMARY

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

                                Company Overview

         We develop, manufacture, market and service medical systems that
deliver precision-focused radio frequency (RF) or microwave energy into diseased
sites of the body, heating them to specified temperatures as required by a
variety of medical therapies. Our business objectives are to commercialize our
products developed for the treatment of cancer and to further expand our
developments to treat other diseases and medical conditions. Our product line
for cancer therapy has been created to offer hospitals and clinics a complete
solution for thermal treatment for cancer provided through microwave/RF systems.

         While our primary developments to date have been cancer treatment
systems, we also pioneered the use of microwave thermal therapy for the
treatment of symptoms associated with enlarged prostate, and we are responsible
for much of the technology that has successfully created a substantial new
medical industry using that therapy. In accordance with our strategic plan, we
subsequently sold our interest in TherMatrx, Inc., the company established to
commercialize our technology to treat enlarged prostate symptoms, to provide
substantial funding that we can utilize for commercializing our systems used in
the treatment of cancer and in achieving other business objectives.

         Our primary mission is to develop the full spectrum of medical uses for
our special competence in precision-focused RF/microwave systems, and to broadly
apply the utilization of our technology to treat cancer and benign diseases and
conditions.

         One of our important contributions to the advancement of medical
therapy has been our pioneering work in developing a new treatment for
conditions associated with enlargement of the prostate that afflicts most men as
they age. As the prostate enlarges it constricts urine flow. The condition is
known medically as benign prostatic hyperplasia or BPH. We developed a
technology that allows men to be treated for BPH through an outpatient procedure
as an alternative to surgery or a lengthy regimen of medication.

         We determined early in our planning that we would treat our development
of BPH therapy as a spin-off business with the intent of providing funding for
our primary business objectives. As a result, we introduced the opportunity to
investment groups and subsequently on October 31, 1997 entered into an agreement
with investors Oracle Strategic Partners, L. P. and Charles Manker. Together we
established a new company, TherMatrx, Inc. TherMatrx received capital from these
investors to conduct clinical trials, and after obtaining FDA approval in July
2001, the funding to commercialize the development. We were compensated for
providing manufacturing, regulatory and engineering support to assure the
success of the new company.

         On July 15, 2004, TherMatrx, Inc. was sold to American Medical Systems
Holdings, Inc. (AMS). Our part of the total proceeds from this sale was



                                       1
<PAGE>

approximately 25%. A portion of the payout from the sale was based on
contingency payments. By the close of fiscal 2006, we had concluded the receipt
of contingency payments from the TherMatrx sale; the payout to us, including
contingency payments, being approximately $33.5 million.

         Since the founding of the Company, 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 hyperthermia therapy. However, hyperthermia therapy has not been
widely accepted as a cancer therapy and reimbursement for hyperthermia therapy
needs to increase in order for the therapy to be viable for hospitals and
treatment centers.

         Our principal executive offices are located at 2188 West 2200 South,
Salt Lake City, Utah 84101, and our telephone number is (801) 972-5555.

                                  The Offering

         The Selling Stockholders identified in this prospectus are selling up
to 966,960 shares of our Common Stock previously issued, or that will be issued,
upon the exercise of stock options granted under the BSD Medical Corporation
1998 Stock Incentive Plan (the "1998 Plan") and that are held by the Selling
Stockholders. 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. 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 operating losses and such losses may
continue in the future.

         Since our inception in 1978, our expenses have exceeded our revenue,
resulting in continuing losses and an accumulated deficit of $1,076,414 at
February 28, 2007. For the six months then ended we recorded a net loss of
$1,574,456. In fiscal 2006, we recorded a net profit of $9,249,496 which
eliminated the accumulated deficit and resulted in positive retained earnings of
$498,042 as of August 31, 2006.

         Our net profit in fiscal year 2006 was primarily due to the sale of our
ownership in TherMatrx, to American Medical Systems Holdings, Inc., or AMS.
Substantially all revenues from this sale have now been received with no


                                       2
<PAGE>

significant future revenues expected. 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 have been unable to do this in
the past and we may be unable to do so in the future, 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 gained wide acceptance by
cancer-treating physicians. We believe this is due in part to the lingering
impression created by 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 payors to make our
products commercially viable, and we believe that reimbursement rates have not
been adequate to stimulate strong interest in adopting hyperthermia as a new
cancer therapy. If our sales and marketing efforts to promote hyperthermia
therapy acceptance in the medical community fail, or our efforts to improve
third-party reimbursement rates for hyperthermia therapy are not successful,
then our future revenue from sales of our products may be limited, and we may
never be able to obtain profitable recurring operations.

         Sales of our product could be significantly reduced if government,
private health insurers and other third-party payors do not provide sufficient
coverage or reimbursement.

         Our success in selling our products will depend in large part on the
extent to which reimbursement for the costs of our products and related
treatments are available from government health agencies, private health
insurers and other third-party payors. Despite the existence of general
reimbursement policies, local medical review policies may differ for public and
private insurance payors, which may cause payment to be refused for some
hyperthermia treatments. Private payors also may refuse to pay for hyperthermia
treatments.

         Medical reimbursement rates are unpredictable and we cannot predict the
extent to which our business may be affected by future legislative and
regulatory developments. Future health care legislation or regulation may limit
our business or impose additional delays and costs on our business and
third-party reimbursement may not be adequate to cover our costs associated with
producing and selling our products.

         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 revenue will decline, we
may never achieve profitability, and we may not be able to continue in business.



                                       3
<PAGE>

         Some of the medical institutions to which we have sold in the past have
not been able to pay for their equipment, and some of our sales have therefore
become substantial bad debts, a risk that could continue into the future.

         Some of our customers have been developing clinics, and these customers
have been particularly vulnerable to financial difficulties that can cause them
to be unable to pay for equipment that they have purchased. If we choose to
accept higher risk sales opportunities to clinics in the future, we will be
subject to these customer credit risks that could lower future net sales due to
bad-debt write offs, resulting in losses in future periods and potentially
lowering the value of your stock. While we attempt to provide for foreseeable
doubtful accounts, we cannot assure you that this provision will always be
adequate to cover our credit risks.

         Increasing sales of our hyperthermia systems depends on our ability to
successfully expand our sales distribution channels; we have had failures with
the productivity of new channels of distribution in the past. Expanding our
channels of distribution will also significantly increase our sales expenses,
which could negatively impact our financial performance.

         We believe that the success of our efforts to increase sales of our
hyperthermia systems in the future depends on our ability to successfully expand
our sales distribution channels. Historically, we have sometimes failed in
establishing successful new sales channels.

         We anticipate that the success of our multi-year plan for selling
hyperthermia systems will require expanding our sales and marketing organization
through a combination of direct sales people, distributors and internal and
external marketing expertise. However, as we pursue our marketing plan, there
can be no assurance that we will be successful in securing reliable channels of
distribution to meet our plan through expanded sales. Recruiting and training
new distribution channels can take time and considerable expense. We project
that sales and marketing expenses will increase substantially in the future as
compared to past years. This added expense could have an adverse effect on our
future financial performance that is greater than any potential increases in
sales.

         In addition, there can be no assurance that our channels of
distribution that have been successful in the past will be successful in the
future. We have derived most of our revenue from sales in Europe through our
distributor Medizin-Technik, GmbH, which also purchases equipment components and
parts from us. Medizin-Technik is controlled by Dr. Sennewald, one of our
directors. The loss or ineffectiveness of Medizin-Technik as a distributor and
significant customer could result in lower revenue.

         We are subject to government regulations that can delay our ability to
sell our products and cause us to incur substantial expenses.

         Our research and development efforts, 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


                                       4
<PAGE>

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 is necessary for us to
commercially market these systems in the United States. Obtaining approvals is a
lengthy and expensive process. 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 might 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.

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

         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 reduce our ability to be competitive and generate sales and profitability.

         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
reduce our ability to be competitive and generate sales and profitability.

         A product liability settlement could exceed our ability to pay.

         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. Our product liability
insurance does not cover intended injury, injury or damage resulting from the
intoxication of any person, payment of workers' compensation benefits, injury of
our own employee, injury or damage due to war, damage to property that we own,


                                       5

damage to our work, loss of use of property, patent infringements, pollution
claims, interest payments, depreciation of property, or injury or damage
resulting from asbestos inhalation. We are responsible to pay the first $10,000
resulting from any claim up to a maximum of $50,000 in one year. We cannot
assure you that our product liability insurance will provide adequate coverage
against potential claims that might be made against us. If we were to be subject
to a claim in excess of our coverage or to a claim not covered by our insurance
and the claim succeeded, we would be required to pay the claim from our limited
resources, which would reduce our limited capital resources and liquidity and
reduce capital we could otherwise use to obtain approvals for and market our
products. In addition, liability or alleged liability could harm our business by
diverting the attention and resources of our management and by damaging our
reputation.

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

         Our success will be largely dependent upon the efforts of Paul F.
Turner, our Chairman of the Board, Senior Vice President, and Chief Technology
Officer, 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.

         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 selling shares at attractive prices
when they want to. The average daily trading volume for our stock has varied
significantly from week to week and from month to month, and the trading volume
often varies widely from day to day. 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    market conditions generally for medical and technology stocks.



                                       6
<PAGE>

         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 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 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.

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

         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. The increased difficulties
faced by a third party who wishes 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 the
sale of the shares offered by this prospectus.

                              SELLING STOCKHOLDERS

         This prospectus relates to certain shares of Common Stock that have
been issued, or are issuable upon exercise of stock options granted pursuant to
the 1998 Plan, to the Selling Stockholders, and which may be offered for sale
from time to time. The Selling Stockholders may resell all, a portion, or none
of the shares of Common Stock.

         The following table sets forth the name and position of the Selling
Stockholders, and the information with respect to the number of shares of Common
Stock owned, or which may be owned, by the Selling Stockholders and as adjusted
to give effect to the sale of the shares that may be offered pursuant to this


                                       8

prospectus. Because the Selling Stockholders may from time to time offer all or
some of the shares pursuant to this offering, we cannot estimate the number of
shares that will be held by the Selling Stockholders after completion of the
offering. However, for purposes of the table below, we have assumed that, after
the completion of the offering, none of the shares covered by this prospectus as
of the date of this prospectus will be held by the Selling Stockholders.

         This prospectus also covers any additional shares of our common stock
which become issuable in connection with the shares being registered by reason
of any stock dividend, stock split, recapitalization or other similar
transaction effected without the receipt of consideration which results in an
increase in the number of our outstanding shares of common stock.

         As of May 14, 2007, there were 21,146,689 shares of our Common Stock
issued and outstanding.

                              PLAN OF DISTRIBUTION

         The purpose of the Prospectus is to permit the Selling Stockholders, if
they desire, to offer for sale and sell the Shares they acquired (or, in some
cases, may acquire) pursuant to the 1998 Plan at such times and at such places
as the Selling Stockholders choose.

         The decision to exercise options for Shares, or to sell any Shares, is
within the discretion of the holders thereof, subject generally to the Company's
policies affecting the timing and manner of sale of Common Stock by certain
individuals. There can be no assurance that any of the options will be exercised
or any Shares will be sold by the Selling Stockholders.

         The Selling Stockholders have advised the Company that sales of Shares
may be effected from time to time in one or more types of transactions (which
may include block transactions) on the American Stock Exchange, in the
over-the-counter market, in negotiated transactions, or a combination of such
methods of sale, at market prices prevailing at the time of sale, at fixed
prices (which may be changed) or at negotiated prices. Such transactions may or
may not involve brokers or dealers. The Selling Stockholders have advised the
Company that they have not entered into any agreements, understandings or
arrangements with any underwriters or broker-dealers regarding the sale of their
Shares, nor is there an underwriter or coordinating broker acting in connection
with the proposed sale of the Shares by the Selling Stockholders.



                                       9
<PAGE>

         The Selling Stockholders may effect such transactions by selling Shares
directly to purchasers or to or through broker-dealers, which may act as agents
or principals. Such broker-dealers may receive compensation in the form of
discounts, concessions, or commissions from the Selling Stockholders and/or the
purchasers of Shares for whom such broker-dealers may act as agents or to whom
they sell as principal, or both (which compensation as to a particular
broker-dealer might be in excess of customary commissions).

         The Selling Stockholders and any broker-dealers that act in connection
with the sale of Shares might be deemed to be "underwriters" within the meaning
of Section 2(11) of the Securities Act, and any commissions received by such
broker-dealers and any profit on the resale of the Shares sold by them while
acting as principals might be deemed to be underwriting discounts or commissions
under the Securities Act. The Selling Stockholders may agree to indemnify any
agent, dealer or broker-dealer that participates in transactions involving sales
of the Shares against certain liabilities, including liabilities arising under
the Securities Act.

         Because the Selling Stockholders may be deemed to be "underwriters"
within the meaning of Section 2(11) of the Securities Act, the Selling
Stockholders will be subject to the prospectus delivery requirements of the
Securities Act, which may include delivery through the facilities of the
American Stock Exchange pursuant to Rule 153 under the Securities Act.

         The Company has informed the Selling Stockholders that the
anti-manipulative provisions of Regulation M promulgated under the Securities
Exchange Act of 1934, as amended, may apply to their sales in the market.

         The Selling Stockholders also may resell all or a portion of the Shares
in open market transactions in reliance upon Rule 144 under the Securities Act,
provided they meet the criteria and conform to the requirements of such Rule.

                                  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.

                                     EXPERTS

              of updating such description.

Item 6.  Indemnification of Directors and Officers.

         Indemnification

         Section 145 of the Delaware General Corporation Law grants the Company
the power to indemnify its officers and directors, under certain circumstances
and subject to certain conditions and limitations as stated therein, against all
expenses and liabilities incurred by or imposed upon them as a result of suits
brought against them as such officers and directors if they act in good faith
and in a manner they reasonably believe to be in or not opposed to the best
interests of the Company, and, with respect to any criminal action or
proceeding, have no reasonable cause to believe their conduct was unlawful.

         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 the Company's Amended and Restated Certificate of
Incorporation provides for the indemnification of directors to the fullest
extent permissible under Delaware law.

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

      Liability Insurance

         Section 145 of the Delaware General Corporation Law also permits a
Delaware corporation to purchase and maintain insurance on behalf of its
directors and officers. The Company's bylaws permit the registrant to purchase
such insurance on behalf of its directors and officers. The Company maintains a
policy of liability insurance for its officers and directors.

Item 9.   Undertakings.

         (a) 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 of 1933, as amended (the "Securities Act");

                     (ii) To reflect in the prospectus any facts or events
              arising after the effective date of the Registration Statement (or
              the most recent post-effective amendment thereof) which,
              individually or in the aggregate, represent a fundamental change
              in the information set forth in the Registration Statement.
              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 range may be reflected in the form of prospectus filed
              with the Commission pursuant to Rule 424(b) if, in the aggregate,
              the changes in volume and price represent no more than a 20%
              change in the maximum aggregate offering price set forth in the
              "Calculation of Registration Fee" table in the effective
              Registration Statement; and

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

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

              (2) That, for the purpose of determining any liability under the
         Securities Act, each such post-effective amendment shall be deemed to


                                       13
<PAGE>

         be a new Registration Statement relating to the securities offered
         therein, and the offering of such securities at that time shall be
         deemed to be the initial bona fide offering thereof.

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

         (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in the Registration Statement
shall be deemed to be a new Registration Statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

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

PROSPECTUS SUMMARY

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

                                Company Overview

         We develop, manufacture, market and service medical systems that
deliver precision-focused radio frequency (RF) or microwave energy into diseased
sites of the body, heating them to specified temperatures as required by a
variety of medical therapies. Our business objectives are to commercialize our
products developed for the treatment of cancer and to further expand our
developments to treat other diseases and medical conditions. Our product line
for cancer therapy has been created to offer hospitals and clinics a complete
solution for thermal treatment for cancer provided through microwave/RF systems.

         While our primary developments to date have been cancer treatment
systems, we also pioneered the use of microwave thermal therapy for the
treatment of symptoms associated with enlarged prostate, and we are responsible
for much of the technology that has successfully created a substantial new
medical industry using that therapy. In accordance with our strategic plan, we
subsequently sold our interest in TherMatrx, Inc., the company established to
commercialize our technology to treat enlarged prostate symptoms, to provide
substantial funding that we can utilize for commercializing our systems used in
the treatment of cancer and in achieving other business objectives.

         Our primary mission is to develop the full spectrum of medical uses for
our special competence in precision-focused RF/microwave systems, and to broadly
apply the utilization of our technology to treat cancer and benign diseases and
conditions.

         One of our important contributions to the advancement of medical
therapy has been our pioneering work in developing a new treatment for
conditions associated with enlargement of the prostate that afflicts most men as
they age. As the prostate enlarges it constricts urine flow. The condition is
known medically as benign prostatic hyperplasia or BPH. We developed a
technology that allows men to be treated for BPH through an outpatient procedure
as an alternative to surgery or a lengthy regimen of medication.

         We determined early in our planning that we would treat our development
of BPH therapy as a spin-off business with the intent of providing funding for
our primary business objectives. As a result, we introduced the opportunity to
investment groups and subsequently on October 31, 1997 entered into an agreement
with investors Oracle Strategic Partners, L. P. and Charles Manker. Together we
established a new company, TherMatrx, Inc. TherMatrx received capital from these
investors to conduct clinical trials, and after obtaining FDA approval in July
2001, the funding to commercialize the development. We were compensated for
providing manufacturing, regulatory and engineering support to assure the
success of the new company.

         On July 15, 2004, TherMatrx, Inc. was sold to American Medical Systems
Holdings, Inc. (AMS). Our part of the total proceeds from this sale was

                                       1
approximately 25%. A portion of the payout from the sale was based on
contingency payments. By the close of fiscal 2006, we had concluded the receipt
of contingency payments from the TherMatrx sale; the payout to us, including
contingency payments, being approximately $33.5 million.

         Since the founding of the Company, 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 hyperthermia therapy. However, hyperthermia therapy has not been
widely accepted as a cancer therapy and reimbursement for hyperthermia therapy
needs to increase in order for the therapy to be viable for hospitals and
treatment centers.

         Our principal executive offices are located at 2188 West 2200 South,
Salt Lake City, Utah 84101, and our telephone number is (801) 972-5555.

                                  The Offering

         The Selling Stockholders identified in this prospectus are selling up
to 966,960 shares of our Common Stock previously issued, or that will be issued,
upon the exercise of stock options granted under the BSD Medical Corporation
1998 Stock Incentive Plan (the "1998 Plan") and that are held by the Selling
Stockholders. 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. 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 operating losses and such losses may
continue in the future.

         Since our inception in 1978, our expenses have exceeded our revenue,
resulting in continuing losses and an accumulated deficit of $1,076,414 at
February 28, 2007. For the six months then ended we recorded a net loss of
$1,574,456. In fiscal 2006, we recorded a net profit of $9,249,496 which
eliminated the accumulated deficit and resulted in positive retained earnings of
$498,042 as of August 31, 2006.

         Our net profit in fiscal year 2006 was primarily due to the sale of our
ownership in TherMatrx, to American Medical Systems Holdings, Inc., or AMS.
Substantially all revenues from this sale have now been received with no

                                       2
significant future revenues expected. 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 have been unable to do this in
the past and we may be unable to do so in the future, 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 gained wide acceptance by
cancer-treating physicians. We believe this is due in part to the lingering
impression created by 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 payors to make our
products commercially viable, and we believe that reimbursement rates have not
been adequate to stimulate strong interest in adopting hyperthermia as a new
cancer therapy. If our sales and marketing efforts to promote hyperthermia
therapy acceptance in the medical community fail, or our efforts to improve
third-party reimbursement rates for hyperthermia therapy are not successful,
then our future revenue from sales of our products may be limited, and we may
never be able to obtain profitable recurring operations.

         Sales of our product could be significantly reduced if government,
private health insurers and other third-party payors do not provide sufficient
coverage or reimbursement.

         Our success in selling our products will depend in large part on the
extent to which reimbursement for the costs of our products and related
treatments are available from government health agencies, private health
insurers and other third-party payors. Despite the existence of general
reimbursement policies, local medical review policies may differ for public and
private insurance payors, which may cause payment to be refused for some
hyperthermia treatments. Private payors also may refuse to pay for hyperthermia
treatments.

         Medical reimbursement rates are unpredictable and we cannot predict the
extent to which our business may be affected by future legislative and
regulatory developments. Future health care legislation or regulation may limit
our business or impose additional delays and costs on our business and
third-party reimbursement may not be adequate to cover our costs associated with
producing and selling our products.

         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 revenue will decline, we
may never achieve profitability, and we may not be able to continue in business.

                                       3
Some of the medical institutions to which we have sold in the past have
not been able to pay for their equipment, and some of our sales have therefore
become substantial bad debts, a risk that could continue into the future.

         Some of our customers have been developing clinics, and these customers
have been particularly vulnerable to financial difficulties that can cause them
to be unable to pay for equipment that they have purchased. If we choose to
accept higher risk sales opportunities to clinics in the future, we will be
subject to these customer credit risks that could lower future net sales due to
bad-debt write offs, resulting in losses in future periods and potentially
lowering the value of your stock. While we attempt to provide for foreseeable
doubtful accounts, we cannot assure you that this provision will always be
adequate to cover our credit risks.

         Increasing sales of our hyperthermia systems depends on our ability to
successfully expand our sales distribution channels; we have had failures with
the productivity of new channels of distribution in the past. Expanding our
channels of distribution will also significantly increase our sales expenses,
which could negatively impact our financial performance.

         We believe that the success of our efforts to increase sales of our
hyperthermia systems in the future depends on our ability to successfully expand
our sales distribution channels. Historically, we have sometimes failed in
establishing successful new sales channels.

         We anticipate that the success of our multi-year plan for selling
hyperthermia systems will require expanding our sales and marketing organization
through a combination of direct sales people, distributors and internal and
external marketing expertise. However, as we pursue our marketing plan, there
can be no assurance that we will be successful in securing reliable channels of
distribution to meet our plan through expanded sales. Recruiting and training
new distribution channels can take time and considerable expense. We project
that sales and marketing expenses will increase substantially in the future as
compared to past years. This added expense could have an adverse effect on our
future financial performance that is greater than any potential increases in
sales.

         In addition, there can be no assurance that our channels of
distribution that have been successful in the past will be successful in the
future. We have derived most of our revenue from sales in Europe through our
distributor Medizin-Technik, GmbH, which also purchases equipment components and
parts from us. Medizin-Technik is controlled by Dr. Sennewald, one of our
directors. The loss or ineffectiveness of Medizin-Technik as a distributor and
significant customer could result in lower revenue.

         We are subject to government regulations that can delay our ability to
sell our products and cause us to incur substantial expenses.

         Our research and development efforts, 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

                                       4
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 is necessary for us to
commercially market these systems in the United States. Obtaining approvals is a
lengthy and expensive process. 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 might 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.

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

         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 reduce our ability to be competitive and generate sales and profitability.

         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
reduce our ability to be competitive and generate sales and profitability.

         A product liability settlement could exceed our ability to pay.

         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. Our product liability
insurance does not cover intended injury, injury or damage resulting from the
intoxication of any person, payment of workers' compensation benefits, injury of
our own employee, injury or damage due to war, damage to property that we own,

                                       5
damage to our work, loss of use of property, patent infringements, pollution
claims, interest payments, depreciation of property, or injury or damage
resulting from asbestos inhalation. We are responsible to pay the first $10,000
resulting from any claim up to a maximum of $50,000 in one year. We cannot
assure you that our product liability insurance will provide adequate coverage
against potential claims that might be made against us. If we were to be subject
to a claim in excess of our coverage or to a claim not covered by our insurance
and the claim succeeded, we would be required to pay the claim from our limited
resources, which would reduce our limited capital resources and liquidity and
reduce capital we could otherwise use to obtain approvals for and market our
products. In addition, liability or alleged liability could harm our business by
diverting the attention and resources of our management and by damaging our
reputation.

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

         Our success will be largely dependent upon the efforts of Paul F.
Turner, our Chairman of the Board, Senior Vice President, and Chief Technology
Officer, 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.

         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 selling shares at attractive prices
when they want to. The average daily trading volume for our stock has varied
significantly from week to week and from month to month, and the trading volume
often varies widely from day to day. 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    market conditions generally for medical and technology stocks.

                                       6
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 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 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.

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

         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. The increased difficulties
faced by a third party who wishes 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 the
sale of the shares offered by this prospectus.

                              SELLING STOCKHOLDERS

         This prospectus relates to certain shares of Common Stock that have
been issued, or are issuable upon exercise of stock options granted pursuant to
the 1998 Plan, to the Selling Stockholders, and which may be offered for sale
from time to time. The Selling Stockholders may resell all, a portion, or none
of the shares of Common Stock.

         The following table sets forth the name and position of the Selling
Stockholders, and the information with respect to the number of shares of Common
Stock owned, or which may be owned, by the Selling Stockholders and as adjusted
to give effect to the sale of the shares that may be offered pursuant to this

                                       8
prospectus. Because the Selling Stockholders may from time to time offer all or
some of the shares pursuant to this offering, we cannot estimate the number of
shares that will be held by the Selling Stockholders after completion of the
offering. However, for purposes of the table below, we have assumed that, after
the completion of the offering, none of the shares covered by this prospectus as
of the date of this prospectus will be held by the Selling Stockholders.

         This prospectus also covers any additional shares of our common stock
which become issuable in connection with the shares being registered by reason
of any stock dividend, stock split, recapitalization or other similar
transaction effected without the receipt of consideration which results in an
increase in the number of our outstanding shares of common stock.

         As of May 14, 2007, there were 21,146,689 shares of our Common Stock
issued and outstanding.

                              PLAN OF DISTRIBUTION

         The purpose of the Prospectus is to permit the Selling Stockholders, if
they desire, to offer for sale and sell the Shares they acquired (or, in some
cases, may acquire) pursuant to the 1998 Plan at such times and at such places
as the Selling Stockholders choose.

         The decision to exercise options for Shares, or to sell any Shares, is
within the discretion of the holders thereof, subject generally to the Company's
policies affecting the timing and manner of sale of Common Stock by certain
individuals. There can be no assurance that any of the options will be exercised
or any Shares will be sold by the Selling Stockholders.

         The Selling Stockholders have advised the Company that sales of Shares
may be effected from time to time in one or more types of transactions (which
may include block transactions) on the American Stock Exchange, in the
over-the-counter market, in negotiated transactions, or a combination of such
methods of sale, at market prices prevailing at the time of sale, at fixed
prices (which may be changed) or at negotiated prices. Such transactions may or
may not involve brokers or dealers. The Selling Stockholders have advised the
Company that they have not entered into any agreements, understandings or
arrangements with any underwriters or broker-dealers regarding the sale of their
Shares, nor is there an underwriter or coordinating broker acting in connection
with the proposed sale of the Shares by the Selling Stockholders.

                                       9
The Selling Stockholders may effect such transactions by selling Shares
directly to purchasers or to or through broker-dealers, which may act as agents
or principals. Such broker-dealers may receive compensation in the form of
discounts, concessions, or commissions from the Selling Stockholders and/or the
purchasers of Shares for whom such broker-dealers may act as agents or to whom
they sell as principal, or both (which compensation as to a particular
broker-dealer might be in excess of customary commissions).

         The Selling Stockholders and any broker-dealers that act in connection
with the sale of Shares might be deemed to be "underwriters" within the meaning
of Section 2(11) of the Securities Act, and any commissions received by such
broker-dealers and any profit on the resale of the Shares sold by them while
acting as principals might be deemed to be underwriting discounts or commissions
under the Securities Act. The Selling Stockholders may agree to indemnify any
agent, dealer or broker-dealer that participates in transactions involving sales
of the Shares against certain liabilities, including liabilities arising under
the Securities Act.

         Because the Selling Stockholders may be deemed to be "underwriters"
within the meaning of Section 2(11) of the Securities Act, the Selling
Stockholders will be subject to the prospectus delivery requirements of the
Securities Act, which may include delivery through the facilities of the
American Stock Exchange pursuant to Rule 153 under the Securities Act.

         The Company has informed the Selling Stockholders that the
anti-manipulative provisions of Regulation M promulgated under the Securities
Exchange Act of 1934, as amended, may apply to their sales in the market.

         The Selling Stockholders also may resell all or a portion of the Shares
in open market transactions in reliance upon Rule 144 under the Securities Act,
provided they meet the criteria and conform to the requirements of such Rule.

                                  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.

                                     EXPERTS

         Tanner LC, independent registered public accountants, have audited our
financial statements incorporated by reference in this prospectus for the year
ended August 31, 2006, as set forth in their report which is incorporated by
reference in this prospectus and elsewhere in the registration statement. Our
financial statements are incorporated by reference in reliance on Tanner LC's
report, given on their authority as experts in accounting and auditing.

Item 6.  Indemnification of Directors and Officers.

         Indemnification

         Section 145 of the Delaware General Corporation Law grants the Company
the power to indemnify its officers and directors, under certain circumstances
and subject to certain conditions and limitations as stated therein, against all
expenses and liabilities incurred by or imposed upon them as a result of suits
brought against them as such officers and directors if they act in good faith
and in a manner they reasonably believe to be in or not opposed to the best
interests of the Company, and, with respect to any criminal action or
proceeding, have no reasonable cause to believe their conduct was unlawful.

         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 the Company's Amended and Restated Certificate of
Incorporation provides for the indemnification of directors to the fullest
extent permissible under Delaware law.

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

      Liability Insurance

         Section 145 of the Delaware General Corporation Law also permits a
Delaware corporation to purchase and maintain insurance on behalf of its
directors and officers. The Company's bylaws permit the registrant to purchase
such insurance on behalf of its directors and officers. The Company maintains a
policy of liability insurance for its officers and directors.

Item 9.   Undertakings.

         (a) 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 of 1933, as amended (the "Securities Act");

                     (ii) To reflect in the prospectus any facts or events
              arising after the effective date of the Registration Statement (or
              the most recent post-effective amendment thereof) which,
              individually or in the aggregate, represent a fundamental change
              in the information set forth in the Registration Statement.
              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 range may be reflected in the form of prospectus filed
              with the Commission pursuant to Rule 424(b) if, in the aggregate,
              the changes in volume and price represent no more than a 20%
              change in the maximum aggregate offering price set forth in the
              "Calculation of Registration Fee" table in the effective
              Registration Statement; and

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

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

              (2) That, for the purpose of determining any liability under the
         Securities Act, each such post-effective amendment shall be deemed to

                                       13
be a new Registration Statement relating to the securities offered
         therein, and the offering of such securities at that time shall be
         deemed to be the initial bona fide offering thereof.

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

         (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in the Registration Statement
shall be deemed to be a new Registration Statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

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

         Pursuant to the requirements of the Securities Act of 1933, the

of the requirements for filing on Form S-8 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Salt Lake City, State of Utah, on May 14, 2007.
