                               PROSPECTUS SUMMARY

About Generex

Generex Biotechnology Corporation is a Delaware corporation engaged in the
research and development of injection-free methods for delivery of large
molecule drugs. We are a development stage company.

To date, we have focused most of our efforts and resources on a platform
technology to orally administer large molecule drugs by absorption through the
walls of the mouth cavity. The mouth cavity is also known as the "buccal"
cavity. Large molecule drugs include proteins, hormones, peptides and vaccines.
Large molecule drugs, such as synthetic insulin, are presently administered
almost exclusively by injection.

The initial product that we have been trying to develop is an oral insulin
formulation for use in the treatment of diabetes. The formulation is sprayed
into the mouth using our RapidMist(TM) device, a small and lightweight aerosol
applicator that administers a metered dose for absorption. Absorption occurs
through the mucous membranes in the buccal cavity.

We have also pursued the application of our technology for the buccal delivery
of pharmaceutical products in addition to insulin, such as the buccal delivery
of morphine, fentanyl citrate and low molecular weight heparin.

Our principal offices are located at 33 Harbour Square, Suite 202, Toronto,
Ontario, Canada M5J 2G2 and our telephone number is (416) 364-2551.

                                  RISK FACTORS

Investment in our shares involves a high degree of risk. You should consider the
following discussion of risks as well as other information in this prospectus
before purchasing any shares. Each of these risk factors could adversely affect
our business, operating results and financial condition, as well as adversely
affect the value of an investment in our common stock.

An investment in our stock is very speculative and involves a high degree of
risk. You should consider the following important factors, as well as the other
information in this Report and the other reports that we have filed heretofore
(and will file hereafter) with the Securities and Exchange Commission, carefully
before purchasing our stock. The following discussion outlines certain factors
that we think could cause our actual outcomes and results to differ materially
from our forward-looking statements.

Our technologies and products are at an early stage of development.

We are a development stage company. We have a very limited history of operations
and we do not expect ongoing revenues from operations in the immediately
foreseeable future. We have no products approved for commercial sale at the
present time. To be profitable, we must successfully research, develop, obtain
regulatory approval for, manufacture, introduce, market and distribute our
products under development. We may not be successful in one or more of these
stages of the development of our products, and/or any of the products we develop
may not be commercially viable.

While over 700 patients with diabetes have been dosed with our oral insulin
formulation at approved facilities in seven countries, our clinical program has
not reached a point where we are prepared to apply for regulatory approvals to
market the product in any country.

Clinical trials under our joint venture with a subsidiary of Elan Corporation,
plc. have not yet commenced. At this time, we cannot predict when or if any
clinical trials might commence.

We believe that we can use our buccal delivery technology successfully with
other large molecule drugs in addition to insulin. In January 2001, we entered
into a joint venture with a subsidiary of Elan Corporation, plc. ("Elan"). The
purpose of the joint venture is to pursue the application of certain of our and
Elan's drug delivery technologies -- including our large molecule drug delivery
technology -- to pharmaceutical products for the treatment of prostate cancer
and endometriosis and/or the suppression of testosterone and estrogen. In
January 2002, we and Elan agreed to expand the joint venture to encompass the
buccal delivery of morphine for the treatment of pain and agreed to pursue
buccal morphine as the initial pharmaceutical product under the joint venture.
We cannot be certain that we can successfully research, develop, obtain
regulatory approval for, manufacture, introduce, market or distribute the buccal
morphine product to be developed under the joint venture with Elan, nor can we
be certain that any buccal morphine product we may develop will be commercially
viable. Similarly, we cannot be certain that we can successfully research,
develop, obtain regulatory approval for and eventually commercialize any product
for which we have completed proof of concept studies. Proof of concept studies
are the very first step in the long process of product development. It could be
years before we will know whether a product for which we might have completed a
successful proof of concept will be commercially viable.

We have not, and may not, receive regulatory approval to sell our products.

We have engaged primarily in research and development activities since our
inception. We have no products approved for commercial sale by drug regulatory
authorities. We have begun the regulatory approval process for our oral insulin
formulation, buccal morphine and fentanyl products.

                                       2


Pre-clinical and clinical trials of our products, and the manufacturing and
marketing of our technology, are subject to extensive, costly and rigorous
regulation by governmental authorities in the United States, Canada and other
countries. The process of obtaining required regulatory approvals from the FDA
and other regulatory authorities often takes many years, is expensive and can
vary significantly based on the type, complexity and novelty of the product
candidates. We cannot assure you that any technologies or products developed by
us, either independently or in collaboration with others, will meet the
applicable regulatory criteria in order to receive the required approvals for
manufacturing and marketing. Delays in obtaining United States or foreign
approvals for our products could result in substantial additional costs to us,
and, therefore, could adversely affect our ability to compete with other
companies. If regulatory approval is ultimately granted, the approval may place
limitations on the intended use of the product we wish to commercialize, and may
restrict the way in which we are permitted to market the product.

We may not be able to develop our insulin product successfully. In order to
obtain regulatory approvals for our insulin product, it will be necessary to
demonstrate, among other things, that:

    o  the product is physically and chemically stable under a range of storage,
       shipping and usage conditions;
    o  the results of administering the product to patients are reproducible in
       terms of the amounts of insulin delivered to the oral cavity and absorbed
       in the bloodstream; and
    o  there are no serious adverse safety issues associated with use of the
       product.

There is even greater uncertainty and risk related to the regulatory approval
process for other products besides our insulin product that may be developed,
whether with partners or independently. This is because we have not developed
any other product candidate to the extent that we have developed the insulin
product.

For similar reasons, we also cannot be certain that we will be able to
successfully secure regulatory approval or develop a buccal morphine product or
any other product chosen for development under the joint venture with Elan.

We may not become, or stay, profitable even if our products are approved for
sale.

Even if regulatory approval to market our oral insulin product or any other
product candidate is obtained, many factors may prevent the product from ever
being sold in commercial quantities. Some of these factors are beyond our
control, such as:

    o  acceptance of the formulation by health care professionals and diabetic
       patients;
    o  the availability, effectiveness and relative cost of alternative diabetes
       treatments that may be developed by competitors; and
    o  the availability of third-party (i.e., insurer and governmental agency)
       reimbursements.

We are in a highly competitive market and our competitors may develop
alternative therapies.

We are in competition with pharmaceutical, biotechnology and drug delivery
companies, hospitals, research organizations, individual scientists and
nonprofit organizations engaged in the development of alternative drug delivery
systems or new drug research and testing, as well as with entities producing and
developing injectable drugs. We are aware of a number of companies that are
currently seeking to develop new products and non-invasive alternatives to
injectable drug delivery, including oral delivery systems, intranasal delivery
systems, transdermal systems, and colonic absorption systems. Many of these
companies may have greater research and development capabilities, experience,
manufacturing, marketing, financial and managerial resources than we do.
Accordingly, our competitors may succeed in developing competing technologies,
obtaining FDA approval for products or gaining market acceptance more rapidly
than we can.

                                       3


We may not be able to compete with diabetes treatments now being marketed and
developed by other companies.

Our oral insulin product will compete with existing and new therapies for
treating diabetes, including administration of insulin by injection. We are
aware of a number of companies currently seeking to develop alternative means of
delivering insulin, as well as new drugs intended to replace insulin therapy at
least in part. In the longer term, we also face competition from companies that
seek to develop cures for diabetes through techniques for correcting the genetic
deficiencies that underlie diseases such as diabetes.

We will have to depend upon others for marketing and distribution of our
products, and we may be forced to enter into contracts limiting the benefits we
may receive and the control we have over our products. We intend to rely on
collaborative arrangements with one or more other companies that possess strong
marketing and distribution resources to perform these functions for us. We may
not be able to enter into beneficial contracts, and we may be forced to enter
into contracts for the marketing and distribution of our products that
substantially limit the potential benefits to us from commercializing these
products. In addition, we will not have the same control over marketing and
distribution that we would have if we conducted these functions ourselves.

Our stock may be delisted from the NASDAQ SmallCap Market and/or become subject
to Penny Stock regulations.

On June 5, 2003, our common stock was delisted from the Nasdaq National Market
because of our failure to maintain a minimum of $10,000,000 in stockholders
equity. We have appealed that decision but the appeal does not stop the
delisting. On June 5, 2003, our stock began trading on the NASDAQ SmallCap
Market. Nasdaq SmallCap has its own standards for continued listing, including a
minimum of $2.5 million stockholders equity. As of April 30, 2003, our
Stockholders Equity was slightly above the minimum.

In addition, for continued listing on both the NASDAQ National Market and
SmallCap Market, our stock price must be at least $1.00. During periods in
fiscal 2002 and the beginning of fiscal 2003, our share price dropped to close
to $1.00 per share. If we do not meet this requirement in the future, we may be
subject to delisting by NASDAQ.

If our stock is delisted from NASDAQ, there will be less interest for our stock
in the market. This may result in lower prices for our stock and make it more
difficult for you to sell your shares.

If our stock is not listed on Nasdaq and fails to maintain a price of $5.00 or
more per share, our stock would become subject to the SEC's "Penny Stock" rules.
These rules require a broker to deliver, prior to any transaction involving a
Penny Stock, a disclosure schedule explaining the Penny Stock Market and its
risks. Additionally, broker/dealers who recommend Penny Stocks to persons other
than established customers and accredited investors must make a special written
suitability determination and receive the purchaser's written agreement to a
transaction prior to the sale. In the event our stock becomes subject to these
rules, it will become more difficult for broker/dealers to sell our common
stock. Therefore shareholders may have more difficulty selling our common stock
in the public market.

                                       4

We will need additional capital, which may not be available to us when we need
it.

We have incurred substantial losses from operations since our inception, and we
expect to continue to incur substantial losses for the immediately foreseeable
future.

We also may require funds in excess of our existing cash resources:

    o  to proceed under our joint venture with Elan, which requires us to fund
       80.1% of initial product development costs;
    o  to develop our buccal insulin product;
    o  to develop new products based on our buccal delivery technology,
       including clinical testing relating to new products;
    o  to develop or acquire other delivery technologies or other lines of
       business;
    o  to establish and expand our manufacturing capabilities; and
    o  to finance general and administrative and research activities that are
       not related to specific products under development.

We do not expect to receive revenues under any future development agreements
that are sufficient to satisfy all of our cash requirements.

In the past, we have funded most of our development and other costs through
equity financing. We anticipate that our existing capital resources will enable
us to maintain currently planned operations through the next twelve months.
However, this expectation is based on our current operating plan, which could
change as a result of many factors, and we may need additional funding sooner
than anticipated. To the extent operating and capital resources are insufficient
to meet future requirements, we will have to raise additional funds to continue
the development and commercialization of our products. Unforeseen problems,
including materially negative developments in our joint venture with Elan, in
our clinical trials or in general economic conditions could interfere with our
ability to raise additional equity capital or materially adversely affect the
terms upon which such funding is available.

Even if we raise funds through equity financing, it will have a dilutive effect
on existing holders of our shares by reducing their percentage ownership. The
shares may be sold at a time when the market price is low because we need the
funds. This will dilute existing holders more than if our stock price was
higher. In addition, equity financings normally involve shares sold at a
discount to the current market price.

It is also possible that we will be unable to obtain additional funding as and
when we need it. If we were unable to obtain additional funding as and when
needed, we could be forced to delay the progress of certain development efforts.
Such a scenario poses risks. For example, our ability to bring a product to
market and obtain revenues could be delayed, our competitors could develop
products ahead of us, and/or we could be forced to relinquish rights to
technologies, products or potential products.

We depend upon proprietary technology and the status of patents and proprietary
technology is uncertain.

Our long-term success will substantially depend upon our ability to protect our
proprietary technology from infringement, misappropriation, discovery and
duplication and avoid infringing the proprietary rights of others. We currently
have fifteen issued U.S. patents pertaining to aspects of buccal delivery
technology and covering our oral insulin formulation, and we have three U.S.
patent applications and one Canadian patent application pending, also related to
aspects of our buccal delivery technology, our oral insulin formulation and our
oral morphine formulation. In addition, we hold one U.S. patent and two Canadian
patents and have one U.S. application pending that pertains to delivery
technologies other than our buccal delivery technology. We also have an indirect
interest in three drug delivery patents held by another company, Centrum
Biotechnologies, Inc., which is 50% owned by us.

                                       5


Our patent rights, and the patent rights of biotechnology and pharmaceutical
companies in general, are highly uncertain and include complex legal and factual
issues. We cannot be sure that any of our pending patent applications will be
granted, or that any patents that we own or will obtain in the future will be
valid and enforceable and provide us with meaningful protection from
competition. There can be no assurance that we will possess the financial
resources necessary to enforce any of our patents. Patents already issued to us
or our pending applications may become subject to dispute, and any dispute could
be resolved against us. There can also be no assurance that any products that we
(or a licensee) may develop will not infringe upon any patent or other
intellectual property right of a third party.

Furthermore, patent applications are in some situations maintained in secrecy in
the United States until the patents are approved, and in most foreign countries
for a period of time following the date from which priority is claimed. A third
party's pending patent applications may cover technology that we currently are
developing.

We have conducted original research on a number of aspects relating to buccal
drug delivery. While we cannot assure you that any of our products will provide
significant commercial advantage, these patents are intended to provide
protection for important aspects of our technology, including our insulin
formulation and the delivery of our insulin formulation as a spray. Because a
substantial number of patents have been issued in the field of alternative drug
delivery and because patent positions can be highly uncertain and frequently
involve complex legal and factual questions, the breadth of claims obtained in
any application or the enforceability of our patents cannot be predicted. The
coverage claimed in a patent can be significantly reduced before a patent is
issued, either in the United States or abroad. Consequently, we do not know
whether any of our pending or future patent applications will result in the
issuance of patents or, to the extent patents have been issued or will be
issued, whether these patents will be subject to further proceedings limiting
their scope, will provide significant proprietary protection or competitive
advantage, or will be circumvented or invalidated.

There can be no assurance that any products that we (or a licensee) may develop
will not infringe upon any patent or other intellectual property right of a
third party. For example, we are aware of certain patents owned by third parties
that such parties could attempt to use in the future in efforts to affect our
freedom to practice some of the patents that we own or have applied for. Based
upon the science and scope of these third party patents, we believe that the
patents that we own or have applied for do not infringe any such third party
patents, however, there can be no assurance that we could successfully defend
our position, if challenged. We may incur substantial costs if we are required
to defend ourselves in patent suits brought by third parties. These legal
actions could seek damages and seek to enjoin testing, manufacturing and
marketing of the accused product or process. In addition to potential liability
for significant damages, we could be required to obtain a license to continue to
manufacture or market the accused product or process and we cannot assure you
that any license required under any such patent would be made available to us on
acceptable terms, if at all. Litigation may also be necessary to enforce our
patents against others or to protect our trade secrets. Such litigation could
result in substantial expense, and we cannot assure you that any litigation
would be resolved in our favor.

In addition, intellectual property for our technologies and products will be a
crucial factor in our ability to develop and commercialize our products. Large
pharmaceutical companies consider a strong patent portfolio critical when they
evaluate whether to enter into a collaborative arrangement to support the
research, development and commercialization of a technology. Without the
prospect of reasonable intellectual property protection, it would be difficult
for a corporate partner to justify the time and money that is necessary to
complete the development of a product.

We also hold some of our technology as trade secrets. We seek to protect this
information, in part, by confidentiality agreements with our employees,
consultants, advisors and collaborators.

Outcome of an arbitration proceeding with Sands Brothers may result in adverse
effects upon Generex.

Sands Brothers & Co. Ltd. v. Generex Biotechnology Corporation. On October 2,
1998, Sands Brothers & Co. Ltd., a New York City-based investment banking and
brokerage firm, initiated an arbitration against us under New York Stock
Exchange rules. Sands alleged that it had the right to receive, for nominal
consideration, approximately 1.5 million shares of our common stock. Sands based
its claim upon an October 1997 letter agreement that was purported by Sands to
confirm an agreement appointing Sands as the exclusive financial advisor to
Generex Pharmaceuticals, Inc., a subsidiary that we acquired in late 1997. In
exchange therefor, the letter agreement purported to grant Sands the right to
acquire 17% of Generex Pharmaceuticals' common stock for nominal consideration.
Sands claimed that its right to receive shares of Generex Pharmaceuticals'
common stock applies to Generex Biotechnology common stock since outstanding
shares of Generex Pharmaceuticals' common stock were converted into shares of
Generex Biotechnology common stock in the acquisition. Sands' claims also
included additional shares allegedly due as a fee related to that acquisition,
and $144,000 in monthly fees allegedly due under the terms of the purported
agreement.

Pursuant to an arbitration award dated September 22, 1999, the arbitration panel
that heard this case awarded Sands $14,070 and issued a declaratory judgment
requiring us to issue to Sands a warrant to purchase 1,530,020 shares of our
common stock pursuant to and in accordance with the terms of the purported
October 1997 letter agreement. On October 13, 1999, Sands commenced a special
proceeding to confirm the arbitration award in the Supreme Court of the State of
New York, County of New York (the "New York Supreme Court"). On November 10,
1999, we moved to vacate the arbitration award. On March 20, 2000, the New York
Supreme Court granted Sands' petition to confirm the award and denied our motion
to vacate the award. We appealed and on January 23, 2001, the New York State
Appellate Division, First Department (the "Appellate Division"), modified the
judgment of the New York Supreme Court that had confirmed the arbitration award
against us. The Appellate Division affirmed the portion of the New York Supreme
Court judgment that had confirmed the granting of monetary relief of $14,070 to
Sands but modified the judgment to vacate the portion of the arbitration award
directing the issuance to Sands of a warrant to purchase 1,530,020 shares of
Generex Biotechnology common stock. The Appellate Division held that the portion
of the award directing us to issue warrants to Sands is too indefinite to be
enforceable and remanded the matter to the arbitration panel for a final and
definite award with respect to such relief or its equivalent (including possibly
an award of monetary damages). The arbitration panel commenced hearings on the
matters remanded by the Appellate Division in June 2001.

On November 7, 2001, the arbitration panel issued an award again requiring us to
issue to Sands a warrant to purchase 1,530,020 shares of Generex Biotechnology
common stock purportedly pursuant to and in accordance with the terms of the
October 1997 letter agreement. Thereafter, Sands submitted a motion to the
Supreme Court to modify the judgment and to confirm the arbitration panel's
award while we filed a motion with the court to vacate the arbitration award.

On February 25, 2002, the Supreme Court vacated the arbitration panel's November
7, 2001 award to Sands of a warrant to purchase 1,530,020 shares of our common
stock. The Supreme Court concluded that the arbitration panel had "disregarded
the plain meaning" of the directive given by the Appellate Division in the
Appellate Division's January 23, 2001 decision that remanded the matter of the
warrant for reconsideration by the panel. The Supreme Court found that the
arbitration panel's award "lacks a rational basis." The Supreme Court also
remanded the matter to the New York Stock Exchange on the issue of whether the
arbitration panel should be disqualified. Sands appealed the February 25, 2002
order of the Supreme Court to the Appellate Division. We filed a cross-appeal on
issues relating to the disqualification of the arbitration panel.

                                       7

On October 29, 2002, the Appellate Division issued a decision and order
unanimously modifying the lower court's order by remanding the issue of damages
to a new panel of arbitrators and otherwise affirming the lower court's order.
The Appellate Division's decision and order limits the issue of damages before
the new panel of arbitrators to reliance damages which is not to include an
award of lost profits. Reliance damages are out-of-pocket damages incurred by
Sands. The Appellate Division stated that the lower court properly determined
that the arbitration award, which had granted Sands warrants for 1,530,020
shares of the registrant's stock, was "totally irrational."

On November 27, 2002, Sands filed with the Appellate Division a motion to
reargue the appeal, or, in the alternative, for leave to appeal to the Court of
Appeals of New York from the order of the Appellate Division. On March 18, 2003,
the Appellate Division denied Sands' motion. We are not able to estimate an
amount or range of potential loss from this legal proceeding at the present
time.

Our consolidated financial condition would be materially adversely affected to
the extent that Sands receives shares of our common stock for little or no
consideration or substantial monetary damages as a result of this legal
proceeding.

We face significant product liability risks, which may have a negative effect on
our financial performance.

The administration of drugs to humans, whether in clinical trials or
commercially, can result in product liability claims whether or not the drugs
are actually at fault for causing an injury. Furthermore, our products may
cause, or may appear to have caused, serious adverse side effects (including
death) or potentially dangerous drug interactions that we may not learn about or
understand fully until the drug has been administered to patients for some time.
Product liability claims can be expensive to defend and may result in large
judgments or settlements against us, which could have a negative effect on our
financial performance. We maintain product liability insurance in amounts we
believe to be commercially reasonable for our current level of activity and
exposure, but claims could exceed our coverage limits. Furthermore, we cannot be
certain that we will always be able to purchase sufficient insurance at an
affordable price. Even if a product liability claim is not successful, the
adverse publicity and time and expense of defending such a claim may interfere
with our business.

The results and timing of our research and development activities, including
future clinical trials, are difficult to predict, subject to future setbacks
and, ultimately, may not result in any additional pharmaceutical products, which
may adversely affect our business.

In developing our products, we may undertake a range of activities, which
include engaging in discovery research and process development, conducting
pre-clinical and clinical studies, and seeking regulatory approval in the United
States and abroad. In all of these areas, we have relatively limited resources
and compete against larger multinational pharmaceutical companies. Moreover,
even if we undertake these activities in an effective and efficient manner,
regulatory approval for the sale of new pharmaceutical products remains highly
uncertain since, in our industry, the majority of compounds discovered do not
enter clinical studies and the majority of therapeutic candidates fail to show
the human safety and efficacy necessary for regulatory approval and successful
commercialization.

Pre-clinical testing and clinical trials must demonstrate that a product
candidate is safe and efficacious. The results from pre-clinical testing and
early clinical trials may not be predictive of results obtained in subsequent
clinical trials, and we cannot be sure that these clinical trials would
demonstrate the safety and efficacy necessary to obtain regulatory approval for
any product candidates. A number of companies in the biotechnology and
pharmaceutical industries have suffered significant setbacks in advanced
clinical trials, even after obtaining promising results in earlier trials. In
addition, certain clinical trials are conducted with patients having the most
advanced stages of disease. During the course of treatment, these patients may
die or suffer other adverse medical effects for reasons that may not be related
to the pharmaceutical agent being tested. Such events can have a negative impact
on the statistical analysis of clinical trial results.

                                       8


The completion of clinical trials of product candidates may be delayed by many
factors. One such factor is the rate of enrollment of patients. We cannot
control the rate at which patients would present themselves for enrollment, and
we cannot be sure that the rate of patient enrollment would be consistent with
our expectations or be sufficient to enable clinical trials of product
candidates to be completed in a timely manner or at all. Any significant delays
in, or termination of, clinical trials of product candidates can have a material
adverse effect on our business.

We cannot be sure that we will be permitted by regulatory authorities to
undertake additional clinical trials for any product candidates, or that if such
trials are conducted, any product candidates will prove to be safe and
efficacious or will receive regulatory approvals. Any delays in or termination
of these clinical trial efforts can have a material adverse effect on product
development.

Our research and development and marketing efforts are highly dependent at
present on corporate collaborators and other third parties who may not devote
sufficient time, resources and attention to our programs, which may limit our
efforts to successfully develop and market potential products.

Because we have limited resources, we have sought to enter into collaboration
agreements with other pharmaceutical companies that will assist us in
developing, testing, obtaining governmental approval for and commercializing
products using our platform technology. Any collaborator with whom we may enter
into such collaboration agreements may not support fully our research and
commercial interests since our program may compete for time, attention and
resources with such collaborator's internal programs. As such, we cannot be sure
that any corporate collaborators will share our perspectives on the relative
importance of our program, that they will commit sufficient resources to our
program to move it forward effectively, or that the program will advance as
rapidly as it might if we had retained complete control of all research,
development, regulatory and commercialization decisions. Additionally, we may
find it necessary from time to time to seek new or additional partners to assist
us in commercializing our products. It is uncertain whether we would be
successful in establishing any such new or additional relationships.

Third party reimbursement for our products is uncertain.

In both domestic and foreign markets, sales of our potential products depends in
part on the availability of reimbursement for third-party payors such as
government health administration authorities, private health insurers and other
organizations. Third-party payors often challenge the price and
cost-effectiveness of medical products and services. Significant uncertainty
exists as to the reimbursement status of newly approved health care products. We
cannot assure you that any of our products will be reimbursable by third-party
payors. In addition, we cannot assure you that our products will be considered
cost effective or that adequate third-party reimbursement will be available to
enable us to maintain price levels sufficient to realize a profit. Legislation
and regulations affecting the pricing of pharmaceuticals may change before our
products are approved for marketing and any such changes could further limit
reimbursement.

We have a history of losses and may incur additional losses.

To date, we have not been profitable and our accumulated net loss before
preferred stock dividend is approximately $72,000,000 at April 30, 2003. Our
losses have resulted principally from costs incurred in research and
development, including clinical trials, and from general and administrative
costs associated with our operations. While we seek to attain profitability, we
cannot be sure that we will ever achieve product and other revenue sufficient
for us to attain this objective.

Our product candidates are in research or early stages of pre-clinical and
clinical development. We will need to conduct substantial additional research,
development and clinical trials. We will also need to receive necessary
regulatory clearances both in the United States and foreign countries and obtain
meaningful patent protection for and establish freedom to commercialize each of
our product candidates. We cannot be sure that we will obtain required
regulatory approvals, or successfully develop, commercialize, manufacture and
market any other product candidates. We expect that these activities, together
with future general and administrative activities, will result in significant
expenses for the foreseeable future.

                                       9


The price of our shares may be volatile.

There may be wide fluctuation in the price of our shares. These fluctuations may
be caused by several factors including:

    o  announcements of research activities and technology innovations or new
       products by us or our competitors;
    o  changes in market valuation of companies in our industry generally;
    o  variations in operating results;
    o  changes in governmental regulations;
    o  developments in patent and other proprietary rights;
    o  public concern as to the safety of drugs developed by us or others;
    o  results of clinical trials of our products or our competitors' products;
       and
    o  regulatory action or inaction on our products or our competitors'
       products.

From time to time, we may hire companies to assist us in pursuing investor
relations strategies to generate increased volumes of investment in our shares.
Such activities may result, among other things, in causing the price of our
shares to increase on a short-term basis.

Furthermore, the stock market generally and the market for stocks of companies
with lower market capitalizations and small biopharmaceutical companies, like
us, have from time to time experienced, and likely will again experience
significant price and volume fluctuations that are unrelated to the operating
performance of a particular company.

Our outstanding Special Voting Rights Preferred Stock and provisions of our
Certificate of Incorporation could delay or prevent the acquisition or sale of
Generex.

Holders of our Special Voting Rights Preferred Stock have the ability to prevent
any change of control of Generex. Our Vice President of Research and
Development, Dr. Pankaj Modi, owns all of our Special Voting Rights Preferred
Stock. In addition, our Certificate of Incorporation permits our Board of
Directors to designate new series of preferred stock and issue those shares
without any vote or action by the shareholders. Such newly authorized and issued
shares of preferred stock could contain terms that grant special voting rights
to the holders of such shares that make it more difficult to obtain shareholder
approval for an acquisition of Generex or increase the cost of any such
acquisition.

                      NOTE ABOUT FORWARD-LOOKING STATEMENTS

We have made some statements in this prospectus that are forward-looking
statements within the meaning of the Private Securities Litigation Reform Act of
1995. These statements can be identified by introductory words such as
"expects", "plans", "intends", "believes", "will", "estimates", "forecasts",
"projects" or words of similar meaning, and by the fact that they do not relate
strictly to historical or current facts.

Our forward-looking statements address, among other things:

    o  our expectations concerning product candidates for our technology;

                                       10


    o  our expectations concerning existing or potential development and license
       agreements for third-party collaborations and joint ventures;
    o  our expectations of when different phases of clinical activity may
       commence; and
    o  our expectations of when regulatory submissions may be filed or when
       regulatory approvals may be received.

Any or all of our forward-looking statements may turn out to be wrong. They may
be affected by inaccurate assumptions that we might make or by known or unknown
risks and uncertainties. Actual outcomes and results may differ materially from
what is expressed or implied in our forward-looking statements. Among the
factors that could affect future results are:

    o  the inherent uncertainties of product development based on a new and as
       yet not fully proven drug delivery technology;
    o  the risks and uncertainties regarding the actual effect on humans of
       seemingly safe and efficacious formulations when tested clinically;
    o  the inherent uncertainties associated with clinical trials of product
       candidates;
    o  the inherent uncertainties associated with the process of obtaining
       regulatory approval to market product candidates; and
    o  adverse developments in our joint venture with a subsidiary of Elan
       Corporation, plc regarding buccal morphine.

Additional factors that we think could cause our actual outcomes and results to
differ materially from the forward-looking statements also include those
discussed above under the caption "Risk Factors."

Because of the risks and uncertainties associated with forward-looking
statements, you should not place undue reliance on them. Further, any
forward-looking statement speaks only as of the date on which it is made, and we
undertake no obligation to update any forward-looking statement to reflect

No selling shareholder has held a position as a director or executive officer
nor has a material employment relationship with the Company within the past 3
years, other than Steven Peltzman, who serves as our Vice President-Business
Development.

(1) Includes all outstanding shares beneficially owned by the shareholder,
    including, in some cases, shares not registered for sale under this
    prospectus.

(2) Does not include shares issuable upon the exercise of options or warrants
    registered for sale under another of our registration statements. No
    shareholder holds other warrants or options, which when added to the
    outstanding shares held after the offering, will give the shareholder
    beneficial ownership of more than 1% of the Company's common stock.

(3) Includes outstanding shares registered for sale under this prospectus, which
    may not be all of the outstanding shares listed as held by the selling
    shareholders, and the registered shares issuable upon exercise of warrants.

(4) No selling shareholder will beneficially own more than 1% of the Company's
    outstanding shares after the offering, other than Protius Overseas Limited,
    which will own less than 2%. The warrants contain a provision prohibiting
    exercise to the extent it would result in the holder beneficially owning
    more than 9.9% of the Company's common stock.

                              PLAN OF DISTRIBUTION

We are registering the shares of common stock covered by this prospectus on
behalf of the selling shareholders. The selling shareholders may offer and sell
shares from time to time. In addition, a selling shareholder's donees, pledgees,
transferees and other successors in interest may sell shares received from a
named selling shareholder after the date of this prospectus. In that case, the
term "selling shareholders" as used in this prospectus includes such donees,
pledgees, transferees and other successors in interest. The selling shareholders
will act independently of us in making decisions with respect to the timing,
manner and size of each sale. Sales may be made over the Nasdaq SmallCap Market
or otherwise, at then prevailing market prices, at prices related to prevailing
market prices or at negotiated prices. The shares may be sold by way of any
legally available means, including in one or more of the following transactions:

    o  a block trade in which a broker-dealer engaged by a selling shareholder
       attempts to sell the shares as agent but may position and resell a
       portion of the block as principal to facilitate the transaction;
    o  purchases by a broker-dealer as principal and resale by the broker-dealer
       for its account pursuant to this prospectus; and ordinary brokerage
       transactions and transactions in which a broker-dealer solicits
       purchasers.

Transactions under this prospectus may or may not involve brokers or dealers.
The selling shareholders may sell shares directly to purchasers or to or through
broker-dealers, who may act as agents or principals. Broker-dealers engaged by
the selling shareholders may arrange for other broker-dealers to participate in
selling shares. Broker-dealers or agents may receive compensation in the form of
commissions, discounts or concessions from the selling shareholders in amounts
to be negotiated in connection with the sale. Broker-dealers or agents also may
receive compensation in the form of discounts, concessions or commissions from
the purchasers of shares for whom the broker-dealers may act as agents or to
whom they sell as principal, or both. This compensation as to a particular
broker-dealer might exceed customary commissions.

The selling shareholders have advised us that they have not, as of the date of
this prospectus, entered into any agreements, understandings or arrangements
with any underwriters or broker-dealers for the sale of shares, nor is there an
underwriter or coordinating broker acting in connection with the proposed sale
of shares by the selling shareholders. To our knowledge, the selling
shareholders have not entered into any agreement, arrangement or understanding
with any particular broker or market maker with respect to the sale of the
shares covered by this prospectus.

In connection with distributions of the shares or otherwise, the selling
shareholders may enter into hedging transactions with broker-dealers or other
financial institutions. In connection with these transactions, broker-dealers or
financial institutions may engage in short sales of the shares in the course of
hedging the positions they assume with selling shareholders. The selling
shareholders may also:

    o  sell shares short and redeliver the shares to close out these short
       positions;
    o  enter into option or other transactions with broker-dealers or other
       financial institutions that require the delivery to the broker-dealer or
       financial institution of the shares, which the broker- dealer or
       financial institution may resell or otherwise transfer under this
       prospectus;
    o  loan or pledge the shares to a broker-dealer or other financial
       institution that may sell the shares so loaned under this prospectus upon
       a default; or
    o  sell shares covered by this prospectus that qualify for sale under Rule
       144 under the Securities Act of 1933 pursuant to that Rule rather than
       under this prospectus.

The selling shareholders and any broker-dealers participating in the sale of
shares covered by this prospectus may be deemed to be "underwriters" within the
meaning of the Securities Act of 1933 in connection with sales of such shares.
Any commission, discount or concession received by a broker-dealer and any
profit on the resale of shares sold by them while acting as principals might be
deemed to be underwriting discounts or commissions under the Securities Act of
1933.

                                       15


We have agreed to pay the expenses of registering the shares under the
Securities Act of 1933, including registration and filing fees, printing

ITEM 17. UNDERTAKINGS.

         We hereby undertake:

         1. To file, during any period in which offers or sales are being made,
a post-effective amendment to this Registration Statement:

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

                  (b) 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;

                  (c) 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) and (b)
         above do not apply if the information required to be included in a
         post-effective amendment by those paragraphs is contained in periodic
         reports filed by us 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 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.

                                       18


         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.

         4. That, for the purpose of determining any liability under the
Securities Act, each filing of our annual report pursuant to Section 13(a) or
Section 15(d) of the Exchange Act (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to 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.

         5. To deliver or cause to be delivered with the prospectus, to each
person to whom the prospectus is sent or given, the latest annual report to
security holders that is incorporated by reference in the prospectus and
furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3
under the Exchange Act; and, where interim financial information required to be
presented by Article 3 of Regulation S-X are not set forth in the prospectus is
sent or given, the latest quarterly report that is specifically incorporated by
reference in the prospectus to provide such interim financial information.

         6. Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of Generex pursuant to the foregoing provisions, or otherwise, Generex 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 Generex of expenses incurred or paid by a director, officer, or
controlling person of Generex 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, Generex 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.

SIGNATURES

In accordance with the requirements of the Securities Act of 1933, we certify
that we have reasonable grounds to believe that we meet all of the requirements
of filing on Form S-3 and have authorized this Amendment to the Registration
Statement to be signed on our behalf by the undersigned, our President, on the
26 day of June, 2003.
