                                  RISK FACTORS

        You should carefully consider the risks and uncertainties described
below before investing in our ordinary shares. Our business, prospects,
financial condition and results of operations could be adversely affected due to
any of the following risks. In that case, the value of our ordinary shares could
decline, and you could lose all or part of your investment.

Risks Related To Our Business

We are a  development  stage  company at an early  stage in the  development  of
pharmaceutical products and our success is uncertain.

        We are a development stage company at an early stage in the development
of our pharmaceutical products that are designed to treat the underlying causes
of degeneration of the brain and the eye as the aging process progresses. We
have not sufficiently advanced the development of our new lead product
candidate, PBT-2, to market or generate revenues from its commercial
application. We cannot make any assurances that any of our product candidates,
if successfully developed, will generate sufficient or sustainable revenues to
enable us to be profitable.

There is a high  risk that we may not be able to  complete  the  development  of
PBT-1, PBT-2 or develop other pharmaceutical products.

        Although we entered into a licensing and research collaboration
agreement with Schering A.G., a major international pharmaceutical company and
Neuroscience Victoria Ltd., a consortium of Australian universities, research
institutes and teaching hospitals, that will provide up to A$7.5 million for
various projects, including the development of a new Alzheimer's diagnostic, we
cannot make any assurances that we will be able to develop our current or any
future pharmaceutical product candidates adequately to attract a suitable
collaborative partner. Nor can we assure you that the projects initially agreed
to with Schering A.G., or the associated investment by Schering A.G., will not
change with the changing interests of either Schering A.G. or our company. We
are also unable to assure you that our research will lead to the discovery of
additional product candidates, or that any of our current and future product
candidates will be successfully developed, prove to be safe and efficacious in
clinical trials, meet applicable regulatory standards and receive regulatory
approval, be capable of being produced in commercial quantities at reasonable
costs, or be successfully or profitably marketed, either by us or a
collaborative partner. We also cannot make any assurances that the products we
develop will be able to penetrate the potential market for a particular therapy
or indication or gain market acceptance among health care providers, patients
and third-party payors. We cannot predict if or when PBT-1, PBT-2, or any of our
other pharmaceutical products under development will be commercialized.

We will not be able to commercialize any of our product candidates if we fail to
adequately  demonstrate  their safety,  efficacy and  superiority  over existing
therapies.

        Before obtaining regulatory approvals for the commercial sale of any of
our pharmaceutical products, we must demonstrate through pre-clinical testing
and clinical studies that our product candidates are safe and effective for use
in humans for each target indication.

                                       5




Conducting pre-clinical testing and clinical studies is an expensive, protracted
and time-consuming process. Likewise, results from early clinical trials may not
be predictive of results obtained in large-scale, later-stage clinical testing.
In addition, even though a potential drug product shows promising results in
clinical trials, regulatory authorities may not grant the necessary approvals
without sufficient safety and efficacy data.

        We cannot make any assurances that we will be able to undertake further
clinical trials of PBT-1 or commence clinical trials of PBT-2 or our proposed
vaccine as planned, or to demonstrate the safety and efficacy or superiority of
PBT-1 or PBT-2 over existing therapies, or other therapies under development, or
enter into any collaborative arrangement to commercialize PBT-1 or PBT-2 on
terms acceptable to us, or at all. Clinical trial results that show insufficient
safety and efficacy could have a material adverse effect on our business,
financial condition and results of operations.

We may experience delays in our clinical trials that could adversely affect our
business and operations.

        We do not know whether planned clinical trials will begin on time or
whether we will complete any of our clinical trials on schedule or at all. Our
ability to commence and complete clinical trials may be delayed by many factors,
including:

          o    government or regulatory  delays,  including  delays in obtaining
               approvals from applicable hospital ethics committees and internal
               review boards;

          o    slower than expected patient recruitment;

          o    our  inability to  manufacture  sufficient  quantities of our new
               proprietary  compound or our other product candidates or matching
               controls;

          o    unforeseen safety issues; and

          o    lack of efficacy or  unacceptable  toxicity  during the  clinical
               trials.

        Patient enrollment is a function of, among other things, the nature of
the clinical trial protocol, the existence of competing protocols, the size and
longevity of the target patient population, and the availability of patients who
comply with the eligibility criteria for the clinical trial. Delays in planned
patient enrollment may result in increased costs, delays or termination of
clinical trials. Moreover, we rely on third parties to assist us in managing and
monitoring clinical trials. Any failure by these third parties to perform under
their agreements with us may cause the trials to be delayed or result in a
failure to complete the trials.

        Product development costs to our collaborators and us will increase if
we have delays in testing or approvals or if we need to perform more or larger
clinical trials than planned. Significant delays could have a material adverse
effect on the commercial prospects of our product candidates and our business,
financial condition and results of operations.

                                        6






We have limited manufacturing experience, and delays in manufacturing sufficient
quantities of PBT-1 or PBT-2 for pre-clinical and clinical trials may negatively
impact our business and operations.

        We cannot make any assurances that we will be able to manufacture
sufficient quantities of PBT-1, PBT-2 or any of our other product candidates in
a cost-effective or timely manner. Any delays in production would delay our
pre-clinical and human clinical trials which could have a material adverse
effect on our business, financial condition and results of operations.

        We may be required to enter into contracting arrangements with
third parties to manufacture PBT-1, PBT-2 and our other product candidates for
large-scale, later-stage clinical trials. We cannot make any assurances that we
will be able to make the transition to commercial production. We may need to
develop additional manufacturing resources, enter into collaborative
arrangements with other parties who have established manufacturing capabilities,
or have third parties manufacture our products on a contract basis. We cannot
make any assurances that we will have access on acceptable terms to the
necessary and substantial financing that would be required to scale-up
production and develop effective commercial manufacturing processes and
technologies. We also cannot make any assurances that we will be able to enter
into collaborative or contracting arrangements on acceptable terms with parties
that will meet our requirements for quality, quantity and timeliness.

We may require  substantial  additional  financing in the future to sufficiently
fund our operations and research.

        We have been unprofitable to date and expect to incur losses over the
next several years as we expand our drug discovery and development programs and
pre-clinical testing and as we conduct clinical trials of our product
candidates. We cannot make any assurances that our existing cash and cash
equivalents and revenue resources will be sufficient to meet our actual
operating expenses and capital requirements on a long-term basis. Our actual
cash requirements may vary materially from those now planned and will depend
upon numerous factors, including:

          o    the continued progress of our research and development programs;

          o    the timing,  scope, results and costs of pre-clinical studies and
               clinical trials;

          o    the cost,  timing  and  outcome  of  regulatory  submissions  and
               approvals;

          o    determinations  as to the  commercial  potential  of our  product
               candidates;

          o    our ability to  successfully  expand our  contract  manufacturing
               services;

          o    our ability to establish and maintain collaborative arrangements;

          o    the status and timing of competitive developments; and

          o    other factors.

                                        7






        We anticipate that we will require substantial additional funds in order
to achieve our long-term goals and complete the research and development of our
pharmaceutical product candidates. In addition, we will require additional funds
to pursue regulatory clearances, and defend our intellectual property rights,
establish commercial scale manufacturing facilities, develop marketing and sales
capabilities and fund operating expenses. We intend to seek such additional
funding through public or private financings and/or through strategic alliances
or other arrangements with corporate partners. We cannot, however, be certain
that such additional financing will be available from any sources on acceptable
terms, or at all, or that we will be able to establish new strategic alliances
or other arrangements with corporate partners on acceptable terms, or at all.
Any shortfall in funding could result in our having to curtail our operations,
including our research and development activities, which could have a material
adverse effect on our business, financial condition and results of operations.

We  have a  history  of  operating  losses  and  may  not  achieve  or  maintain
profitability in the future.

        We have incurred losses in every period since we began operations in
1997. We expect to continue to incur additional operating losses over at least
the next several years and to increase our cumulative losses substantially as we
expand our research and development and pre-clinical activities and commence
additional clinical trials of PBT-1 and PBT-2. We reported a net loss of
A$5,448,467 and A$4,584,838 during the fiscal years ended June 30, 2002 and
2003, respectively, and a net loss of A$4,037,914 for the six month period ended
December 31, 2003. As of December 31, 2003, our accumulated deficit was
A$19,617,176. We cannot assure you that we will achieve or maintain
profitability.

Our success  depends upon our ability to protect our  intellectual  property and
our proprietary technology.

        Our success will depend in large part on whether we can:

          o    obtain and maintain patents to protect our own products;

          o    obtain licenses to the patented technologies of third parties;

          o    operate  without  infringing on the  proprietary  rights of third
               parties; and

          o    protect our trade secrets and know-how.

        Patent matters in biotechnology are highly uncertain and involve complex
legal and factual questions. Accordingly, the availability and breadth of claims
allowed in biotechnology and pharmaceutical patents cannot be predicted. While
we intend to seek patent protection for our therapeutic products and
technologies, we cannot be certain that any of the pending or future patent
applications filed by us or on our behalf will be approved, or that we will
develop additional proprietary products or processes that are patentable or that
we will be able to license any other patentable products or processes.

        Our commercial success will also depend, in part, on our ability to
avoid infringement of patents issued to others. If a court determines that we
were infringing any third party patents, we

                                       8






could be required to pay damages, alter our products or processes, obtain
licenses or cease certain activities. We cannot be certain that the licenses
required under patents held by third parties would be made available on terms
acceptable to us or at all. To the extent that we are unable to obtain such
licenses, we could be foreclosed from the development, manufacture or
commercialization of the product requiring such license or encounter delays in
product introductions while we attempt to design around such patents, and any of
these circumstances could have a material adverse effect on our business,
financial condition and results of operations.

        We may have to resort to litigation to enforce any patents issued or
licensed to us or to determine the scope and validity of third party proprietary
rights. Any such litigation, regardless of outcome, could be expensive and time
consuming, and adverse determinations in any such proceedings could prevent us
from developing, manufacturing or commercializing our products and could have a
material adverse effect on our business, financial condition and results of
operations.

Our products may infringe on the intellectual  property rights of others,  which
could increase our costs and negatively affect our profitability.

        Third parties may assert against us infringement claims or claims that
we have infringed a patent, copyright, trademark or other proprietary right
belonging to them. Any infringement claim, even if not meritorious, could result
in the expenditure of significant financial and managerial resources and could
negatively affect our profitability.

        We are currently in litigation in the United States District Court for
the District of Columbia concerning the inventorship of our historical lead
compound, PBT-1. If we are not successful in this litigation, or decide that it
is in the best interests of our company to seek alternative means to resolve the
dispute, including such options as entering into a partnership, our future
prospects may be materially impacted. In such a situation we may be required to
license certain rights from P.N. Gerolymatos S.A., or be required to develop a
molecule with similar metal binding characteristics that will act as an
inhibitor in the oxidation process. We cannot provide any assurance that we will
be able to obtain such a license, if required, or that we will be successful in
developing such a molecule. In a situation where resolution of inventorship
results in a license between our company and P.N. Gerolymatos S.A. it is
possible that the license terms may include rights or royalties to PBT-1, PBT-2
and/or our other product candidates.

If we do not obtain the  necessary  governmental  approvals we will be unable to
commercialize our pharmaceutical products.

        Our ongoing research and development activities are, and the production
and marketing of our pharmaceutical product candidates derived therefrom will
be, subject to regulation by numerous governmental authorities in Australia,
principally the Therapeutics Goods Administration, or TGA, and the Food and Drug
Administration, or FDA, in the United States, the Medicines Control Agency in
the United Kingdom and the European Medicines Evaluation Authority. Prior to
marketing, any therapeutic product developed must undergo rigorous pre-clinical
testing and clinical trials, as well as an extensive regulatory approval process
mandated



                                       9




by the TGA and, to the extent that any of our pharmaceutical products under
development are marketed abroad, by foreign regulatory agencies including the
FDA in the United States and the Medicines Control Agency in the United Kingdom.
These processes can take many years and require the expenditure of substantial
resources. Delays in obtaining regulatory approvals would adversely affect the
development and commercialization of our pharmaceutical product candidates. We
cannot be certain that we will be able to obtain the clearances and approvals
necessary for clinical testing or for manufacturing and marketing our
pharmaceutical products candidates.

Our research and  development  efforts will be seriously  jeopardized  if we are
unable to retain  key  personnel  and  cultivate  key  academic  and  scientific
collaborations.

        Our future success depends to a large extent on the continued services
of our senior management and key scientific personnel. We have entered into
employment agreements with these individuals. The loss of their services, could
negatively affect our business. Our success is highly dependent on the continued
contributions of our scientific personnel and on our ability to develop and
maintain important relationships with leading academic institutions and
scientists. Competition among biotechnology and pharmaceutical companies for
qualified employees is intense, and we cannot be certain that we will be able to
continue to attract and retain qualified scientific and management personnel
critical to our success. We also have relationships with leading academic and
scientific collaborators who conduct research at our request or assist us in
formulating our research and development strategies. These academic and
scientific collaborators are not our employees and may have commitments to, or
consulting or advisory contracts with, other entities that may limit their
availability to us. In addition, these collaborators may have arrangements with
other companies to assist such companies in developing technologies that may
prove competitive to ours.

If we are unable to successfully keep pace with technological change or with the
advances of our competitors,  our technology and products may become obsolete or
non-competitive.

        The biotechnology and pharmaceutical industries are subject to rapid and
significant technological change. Our competitors in Australia and elsewhere are
numerous and include major pharmaceutical companies, biotechnology firms,
universities and other research institutions. These competitors may develop
technologies and products that are more effective than any that we are
developing, or which would render our technology and products obsolete or
non-competitive. Many of these competitors have greater financial and technical
resources and manufacturing and marketing capabilities than we do. In addition,
many of our competitors have much more experience than we do in pre-clinical
testing and human clinical trials of new or improved drugs, as well as in
obtaining FDA, TGA and other regulatory approvals.

        We know that competitors are developing or manufacturing various
technologies or products for the treatment of diseases that we have targeted for
product development. Some of these competitive products use therapeutic
approaches that compete directly with certain of our product candidates. Our
ability to further develop our products may be adversely affected if any of our
competitors were to succeed in obtaining regulatory approval for their
competitive products sooner than us.

                                       10




Acceptance  of our  products in the  marketplace  is  uncertain,  and failure to
achieve market acceptance will negatively impact our business and operations.

        We cannot make any assurances that our products will achieve market
acceptance even if they are approved by the TGA and the FDA. The degree of
market acceptance of our products will depend on a number of factors, including:

          o    the receipt and timing of regulatory  approvals for the uses that
               we are studying;

          o    the  establishment  and demonstration to the medical community of
               the  safety,  clinical  efficacy  and  cost-effectiveness  of our
               product  candidates and their potential  advantages over existing
               therapeutics and technologies; and

          o    the  pricing  and  reimbursement   policies  of  governments  and
               third-party payors.

        Physicians, patients, payors or the medical community in general may be
unwilling to accept, use or recommend any of our products.

The failure to establish a sales,  marketing and  distribution  capability would
materially impair our ability to successfully market and sell our pharmaceutical
products.

        We currently have no experience in marketing, sales or distribution of
pharmaceutical products. If we develop any commercially marketable
pharmaceutical products and decide to perform our own sales and marketing
activities, we will require additional management, will need to hire sales and
marketing personnel, and will require additional capital. We cannot make any
assurances that qualified personnel will be available in adequate numbers or at
a reasonable cost, that additional financing will be available on acceptable
terms, or at all, or that our sales staff will achieve success in their
marketing efforts. Alternatively, we may be required to enter into marketing
arrangements with other parties who have established appropriate marketing,
sales and distribution capabilities. We cannot make any assurances that we will
be able to enter into marketing arrangements with any marketing partner or that
if such arrangements are established, our marketing partners will be able to
commercialize our products successfully. Other companies offering similar or
substitute products may have well-established and well-funded marketing and
sales operations in place that will allow them to market their products more
successfully. Failure to establish sufficient marketing capabilities would
materially impair our ability to successfully market and sell our pharmaceutical
products.

If healthcare insurers and other  organizations do not pay for our products,  or
impose limits on reimbursement, our business may suffer.

        The drugs we hope to develop may be rejected by the marketplace due to
many factors, including cost. The continuing efforts of governments, insurance
companies, health maintenance organizations and other payors of healthcare costs
to contain or reduce healthcare costs may affect our future revenues and
profitability and those of our potential customers, suppliers and collaborative
partners, as well as the availability of capital. In Australia and certain
foreign markets, the pricing or profitability of prescription pharmaceuticals is
already subject to government control. We expect initiatives for similar
government control at both the state and

                                       11






federal level to continue in the United States. The adoption of any such
legislative or regulatory proposals could have a material adverse effect on our
business and prospects.

        Our ability to commercially exploit our products successfully will
depend in part on the extent to which reimbursement for the cost of our products
and related treatment will be available from government health administration
authorities, private health coverage insurers and other organizations.
Third-party payors, such as government and private health insurers, are
increasingly challenging the price of medical products and services. Uncertainty
exists as to the reimbursement status of newly approved health care products
thereafter and in foreign markets, including the United States. If third-party
coverage is not available to patients for any of the products we develop, alone
or with collaborators, the market acceptance of these products may be reduced,
which may adversely affect our future revenues and profitability. In addition,
cost containment legislation and reductions in government insurance programs may
result in lower prices for our products and could materially adversely affect
our ability to operate profitably.

We may be exposed to product liability claims, which could harm our business.

        The testing, marketing and sale of human health care products also
entails an inherent risk of product liability. We may incur substantial
liabilities or be required to limit development or commercialization of our
products if we cannot successfully defend ourselves against product liability
claims. We have obtained no fault compensation insurance (of A$10 million) with
respect to our recent clinical trial and extension study and intend to obtain
similar coverage for future clinical trials. We cannot be certain that such
coverage will be available in the future on acceptable terms, or at all. This
may result in our inability to pursue further clinical trials or to obtain
adequate protection in the event of a successful claim. No assurance can be
given that we will be able to obtain product liability insurance in the event of
the commercialization of a product or that it will be available on commercially
reasonable terms. Even if we have adequate insurance coverage, product liability
claims or recalls could result in negative publicity or force us to devote
significant time, attention and financial resources to those matters.

Changes in government legislation and policy may adversely affect us.

        While we do not anticipate in the near future any specific material
changes in government legislation that may adversely affect us, any material
changes in interest rate, exchange rate, relevant taxation and other legal
regimes and government policies may adversely affect us and the market price of
our securities.

We are  dependent  upon a sole  supplier  of our key  component  and could incur
significant costs if we are unable to promptly find a replacement.

        Our lead compound, PBT-2, and our earlier product, PBT-1, are
manufactured by one manufacturer, the Institute of Drug Technology Limited. We
intend to continue this relationship with further compounds if it remains
financially viable. We have not had any prior manufacturer of PBT-1 cease its
relationship with our company. We cannot assure you that we will be able to
promptly find a replacement manufacturer, if required, without incurring
material additional costs.

Risks Relating to Our Ordinary Shares

Our stock price may be volatile  and the U.S.  trading  market for our  American
Depositary Shares is limited.

        The market price for our securities, like that of the securities of
other pharmaceutical and biotechnology companies, has fluctuated substantially
and may continue to be highly volatile in the future. The market price for our
ordinary shares has ranged from as low as A$0.435 to a high of A$2.41 during the
last two years and the market price of our American Depositary Shares has ranged
from as low as US$2.95 to a high of US$12.80 since our listing on the NASDAQ
SmallCap Market on September 5, 2002. The market price for our ordinary shares
has been affected by both broad market developments and announcements relating
to actual or potential developments concerning products under development. We
believe that the following factors, in addition to other risk factors described
above and elsewhere in this registration statement, will continue to
significantly affect the market price of our ordinary shares:

          o    the results of pre-clinical testing and clinical trials by us and
               our competitors;

          o    developments concerning research and development,  manufacturing,
               and  marketing   alliances  or   collaborations  by  us  and  our
               competitors;

          o    announcements  of  technological  innovations  or new  commercial
               products by us and our competitors;

          o    determinations  regarding  our patent  applications  and those of
               others;

          o    publicity  regarding  actual or  potential  results  relating  to
               medicinal products under development by us and our competitors;

          o    proposed governmental  regulations and developments in Australia,
               the United States and elsewhere;

          o    litigation;

          o    economic and other external factors; and

          o    period-to-period fluctuations in our operating results.

        In addition, stock markets have experienced extreme price and volume
fluctuations. These fluctuations have especially affected the stock market price
of many high technology and healthcare related companies, including
pharmaceutical and biotechnology companies, and, in many cases, are unrelated to
the operating performance of the particular companies.

Sales of ADRs under this prospectus may negatively  impact the prevailing market
price of our ADRs.

        This prospectus provides for the disposition of up to 7,000,000 ADRs,
including 3,000,000 ADRs which are issuable upon exercise of warrants held by
the selling shareholders.

                                       13






To date, there has been a limited market for our ADRs on the NASDAQ SmallCap
Market and we are unable to predict the effect that the disposition of the ADRs
subject to this prospectus may have on the prevailing market for our ADRs.

We may incur increased costs as a result of recently enacted changes in laws and
regulations relating to corporate governance matters and public disclosure.

        Recently enacted and proposed changes in the laws and regulations
affecting public companies, including the provisions of the Sarbanes-Oxley Act
of 2002, rules adopted or proposed by the SEC and by the NASDAQ National Market
and new accounting pronouncements will result in increased costs to us as we
evaluate the implications of these laws, regulations and standards and respond
to their requirements. To maintain high standards of corporate governance and
public disclosure, we intend to invest all reasonable necessary resources to
comply with evolving standards. This investment may result in increased general
and administrative expenses and a diversion of management time and attention
from strategic revenue generating and cost management activities. In addition,
these new laws and regulations could make it more difficult or more costly for
us to obtain certain types of insurance, including directors and officers
liability insurance, and we may be forced to accept reduced policy limits and
coverage or incur substantially higher costs to obtain the same or similar
coverage. The impact of these events could also make it more difficult for us to
attract and retain qualified persons to serve on our board of directors, on our
board committees or as executive officers. We are presently evaluating and
monitoring developments with respect to these laws and regulations and cannot
predict or estimate the amount or timing of additional costs we may incur to
respond to their requirements.

Holders  of our  ordinary  shares or  American  Depositary  Shares  who are U.S.
residents face adverse income tax consequences.

        There is a risk that we will be classified as a passive foreign
investment company, or PFIC. Our treatment as a PFIC could result in a reduction
in the after-tax return to the holders of our ordinary shares or American
Depositary Shares and would likely cause a reduction in the value of such
shares. For U.S. federal income tax purposes, we will be classified as a PFIC
for any taxable year in which either (i) 75% or more of our gross income is
passive income, or (ii) at least 50% of the average value of all of our assets
for the taxable year produce or are held for the production of passive income.
For this purpose, passive income includes dividends, interest, royalties, rents,
annuities and the excess of gains over losses from the disposition of assets
which produce passive income. As a result of our cash position, which may
increase if a substantial portion of our outstanding options are exercised,
there is a risk under the asset test described above that we will be declared a
PFIC in the event the price of our ordinary shares declines substantially. If we
were determined to be a PFIC for U.S. federal income tax purposes, highly
complex rules would apply to U.S. holders owning ordinary shares. Accordingly,
you are urged to consult your tax advisors regarding the application of such
rules. However, because the determination of whether we are a PFIC is based upon
the composition of our income and assets from time to time, this determination
can not be made with certainty until the end of the calendar year.

                                       14




We do not intend to pay dividends.

        We have never declared or paid any cash dividends on our ordinary
shares. We currently intend to retain any future earnings to finance operations
and expand our business and, therefore, do not expect to pay any dividends in
the foreseeable future.

Risks Relating to our Location in Australia

It may be  difficult to enforce a judgment in the United  States  against us and
most of our officers and directors or to assert U.S.  securities  laws claims in
Australia or serve process on most of our officers and directors.

        We are incorporated in Australia. Except for one of our executive
officers and one company director, all our executive officers and directors are
nonresidents of the United States. Therefore, it may be difficult for an
investor, or any other person or entity, to enforce a U.S. court judgment based
upon the civil liability provisions of the U.S. federal securities laws in an
Australian court against us or any of those persons or to effect service of
process upon these persons in the United States. Additionally, it may be
difficult for an investor, or any other person or entity, to enforce civil
liabilities under U.S. federal securities laws in original actions instituted in
Australia.

                         CAPITALIZATION AND INDEBTEDNESS

        The table below sets forth the capitalization of our company as of
December 31, 2003 and as adjusted to give effect to the sale of 4,000,000 of our
ADRs (40,000,000 million ordinary shares) at a price of US$5.00 per ADR (at an
exchange rate of A$1.40095 = $1.00), and the receipt of the net proceeds
therefrom.

        This prospectus relates to the disposition of up to 7,000,000 of our
ADRs (each representing ten ordinary shares), of which 4,000,000 ADRs were
issued and 3,000,000 ADRs are issuable upon exercise of certain warrants. We
will not receive any of the proceeds from the disposition by the selling
shareholders of our ADRs. We will, however, receive the proceeds from the
exercise of the warrants if and when they are exercised.

elsewhere in this registration statement. In the opinion of management, the
unaudited condensed interim financial statements are prepared on a basis
consistent with the audited financial statements included in our Annual Report
on Form 20-F for the year ended June 30, 2003 (which is incorporated herein by
reference) and reflect all adjustments, which are of a normal recurring nature,
necessary for a fair presentation of our financial position, results of
operation and cash flows and for such periods and are not necessarily indicative
of a full year's results.

        We prepare our financial statements in accordance with accounting
principles generally accepted in Australia, or A-GAAP, which differ in certain
significant respects from accounting principles generally accepted in the United
States of America, or U.S. GAAP. Please refer to Note 7 to our unaudited interim
condensed financial statements for a description of the principal differences
between A-GAAP and U.S. GAAP as they relate to us, and a reconciliation of net
loss and total equity for the periods and as of the dates therein indicated.

        The selected financial data set forth below should be read in
conjunction with Management's Discussion and Analysis of Financial Condition and
Results of Operations and our audited financial statements contained in our
Annual Report on Form 20-F for the year ended June 30, 2003 which is
incorporated herein by reference.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

        The following discussion of our financial condition and results of
operations should be read together with our unaudited interim condensed
financial statements and the related notes, which appear elsewhere in this
prospectus. The following discussion contains forward-looking statements that
reflect our current plans, estimates and beliefs and involve risks and
uncertainties. Our actual results may differ materially from those discussed in
the forward-looking statements. Factors that could cause or contribute to such
differences include those discussed below and elsewhere in this prospectus,
particularly in the section entitled "Risk Factors."

Results of Operations

Six Months  Ended  December 31, 2003  Compared to Six Months Ended  December 31,
2002

Revenues from ordinary activities

        Revenues from ordinary activities increased to A$1,123,587 for the six
months ended December 31, 2003 from A$526,700 in the same period ended 2002, an
increase of A$596,887, or 113.32%. Revenues in the six months period ended
December 31, 2003 consisted of A$104,326 interest income, A$231,761 government
grant income, and A$787,500 received under the licensing and research
collaboration agreement we entered into with Schering A.G. and Neuroscience
Victoria Limited in March 2003. Revenues in the six months period ended December
31, 2002 consisted of A$57,650 interest income and A$469,050 government grant
income. The increase in revenues is attributable to our agreement with Schering
A.G. and Neuroscience Victoria Limited.

Depreciation and amortization expenses

        Depreciation and amortization expenses increased to A$597,932 for the
six months ended December 31, 2003 from A$588,981 in the same period ended 2002,
an increase of A$8,951, or 1.52%. The increase in expenses is attributable to
the acquisition of additional equipment, including computer equipment.

Patents, research and development expenses

        Patents, research and development expenses increased to A$2,610,456 for
the six months ended December 31, 2003 from A$1,230,195 in the same period ended
2002, an increase of A$1,380,261, or 112.20%. The increase in expenses is
attributable to expenses of A$1,164,375 incurred in connection with the
licensing and research collaboration agreement we entered into with Schering
A.G. and Neuroscience Victoria Limited in March 2003 and pre-clinical trial fees
of A$795,982 in connection with the new government start grant that commenced in
September 2003.

                                       22




Legal expenses

        Legal expenses decreased to A$295,252 for the six months ended December
31, 2003 from A$514,982 in the same period ended 2002, a decrease of A$219,730,
or 42.67%. The decrease in legal expenses was primarily due to a reduction in
legal costs in relation to the Gerolymatos claim as the litigation activity was
suspended during settlement discussions. To date, the Gerolymatos claim has not
been resolved.

Employee benefits expense

        Employee benefits expenses increased to A$499,500 for the six months
ended December 31, 2003 from A$380,616 in the same period ended 2002, an
increase of A$118,884, or 31.23%. The increase in employee benefits expenses was
primarily due to an increase in staff from five persons to nine persons.

Consulting fee expenses

        Consulting fee expenses increased to A$571,807 for the six months ended
December 31, 2003 from A$369,141 in the same period ended 2002, an increase of
A$202,666, or 54.90%. The increase in consulting fee expenses was primarily due
to an increase in directors' fees. The impact of this increase was partially
offset by a decrease in the fees paid to consultants in the scientific advisory
board and the scientific commercial optimization group. The increase in
directors fees arose in part from a one-time back payment of fees to directors
for fees not paid during an extended period of assessment, negotiation and
approval of a new compensation package designed to bring the directors'
remuneration in line with industry standards. Outside expertise from Mercer
Human Resources was sought to determine the appropriate level of compensation
for directors and used as a basis for new compensation terms. The fees of our
scientific advisory board decreased to zero for the six months ended December
31, 2003 from A$67,165 in the same period ended 2002, due to the status of the
changed portfolio of the molecules under development. The fees of the scientific
commercialization optimization group (which was introduced in 2002) decreased to
A$1,000 for the six months ended December 31, 2003 from A$15,000 in the same
period ended 2002, as the group was disbanded in 2003 because it was not
providing our company the advice it required.

Corporate compliance expenses

        Corporate compliance expenses decreased to A$189,439 for the six months
ended December 31, 2003 from A$200,524 in the same period ended 2002, a decrease
of A$11,085, or 5.53%. The decrease in corporate compliance expenses is
primarily attributable to a one-time expense incurred in the six months ended
December 31, 2002 related to our listing on the NASDAQ SmallCap Market in
September 2002, partially offset by an increase in periodic reporting costs due
to enhanced corporate governance requirements.

Other expenses from ordinary activities

        Other expenses from ordinary activities increased to A$397,115 for the
six months ended December 31, 2003 from A$380,776 in the same period ended 2002,
an increase of A$16,341, or 4.29%. The increase in expenses from ordinary
activities is primarily due to increase in foreign

                                       23






exchange losses of A$34,654 and marketing costs of A$84,910, partially offset by
a reduction in computer costs of A$12,279 and travel expenditure of A$80,941.

Differences between U.S. and Australian GAAP

        We prepare our financial statements in accordance with A-GAAP, which
differ in certain significant respects from U.S. GAAP. See Note 7 to our
unaudited interim condensed financial statements for a description of the
principal differences between A-GAAP and U.S. GAAP as they relate to us, and a
reconciliation of net loss and total equity for the dates and periods indicated
therein. Differences between A-GAAP and U.S. GAAP that have a material effect on
net loss and total equity relate to share-based compensation and intangible
assets.

Liquidity and Capital Resources

        Cash and cash equivalents totaled A$5,620,156 at December 31, 2003,
compared to A$3,463,783 at June 30, 2003 and A$3,585,014 at June 30, 2002.

        In September 2003, we raised A$4.7 million, net of issuance costs,
through a private placement of 7.1 million ordinary shares to institutional and
accredited investors at a subscription price of A$0.70 per share.

        In April 2004, we raised in a private placement an additional US$20
million, which was held in escrow pending receipt of the requisite approval of
the transaction by our shareholders that was obtained on June 1, 2004. The
private placement was for four million ADRs to institutional and professional
investors at a price of US$5.00 per ADR. The private placement also involved the
acquisition by the investors of five-year warrants to purchase an additional
three million ADRs at an exercise price of US$8.00 per ADR. Should these
warrants be exercised, we would raise an additional US$24 million.

        We believe our existing cash and cash equivalents as well as anticipated
cash flow from government grants, a licensing and research collaboration
agreement and potential option exercises will be sufficient to support our
current operating plan for the foreseeable future; however, we have based this
estimate on assumptions that may prove to be incorrect. Our future funding
requirements will depend on many factors, including, but not limited to:

          o    costs and timing of obtaining regulatory approvals;

          o    the costs and timing of  obtaining,  enforcing  and defending our
               patent and  intellectual  property  the  progress  and success of
               pre-clinical and clinical trials of our product candidates; and

          o    the progress and number of our research programs in development.

Off-Balance Sheet Arrangements

        We are not a party to any material off-balance sheet arrangements. In
addition, we have no unconsolidated special purpose financing or partnership
entities that are likely to create material contingent obligations.

                                       24






Tabular Disclosure of Contractual Obligations

        The following table summarizes our minimum contractual obligations and
commercial commitments as of December 31, 2003 and the effect we expect them to
have on our liquidity and cash flow in future periods.

                              SELLING SHAREHOLDERS

        The registration statement of which this prospectus forms a part covers
up to 7,000,000 ADRs, each representing ten ordinary shares, of which 4,000,000
ADRs were issued to the selling shareholders and 3,000,000 ADRs are issuable
upon exercise of warrants granted to the selling shareholders. Each of the
selling shareholders has represented that it purchased the ADRs in the ordinary
course of business and has no agreement to distribute the ADRs. We are
registering the shares underlying the ADRs in order to permit the selling
shareholders to dispose of the ADRs from time to time. Except for the ownership
of the ADRs and the warrants, the selling shareholders have not had any material
relationship with us within the past three years.

        The table below lists the selling shareholders and other information
regarding the beneficial ownership of the ordinary shares underlying the ADRs by
each of the selling shareholders. The second and third columns list the number
and percentage of such ordinary shares beneficially owned by each selling
shareholder, based on each selling shareholder's ownership of ordinary shares
and the warrants as of June 4, 2004, assuming full exercise of the warrants held
by each selling shareholder on that date, without regard to any limitations on
exercise.

        The fourth column lists the number of ordinary shares underlying the
ADRs which may be offered by this prospectus by each of the selling
shareholders.

        In accordance with the terms of a registration rights agreement with the
selling shareholders, this prospectus generally covers the resale of at least
100% of that number of ADRs equal to the number of ADRs issued to the selling
shareholders and issuable upon exercise of the warrants granted to the selling
shareholders, determined as if the outstanding warrants were exercised in full
as of the trading day immediately preceding the date this registration statement
was initially filed with the Securities and Exchange Commission. Because the
exercise price of the warrants may be adjusted, the number of ordinary shares
that will actually be issued may be more or less than the number of ordinary
shares covered by this prospectus. The fifth and sixth columns assume the sale
of all of the ordinary shares underlying the ADRs offered by the selling
shareholders pursuant to this prospectus.

        Under the terms of the warrants, the selling shareholders may not
exercise the warrants, to the extent such exercise would cause a selling
shareholder, together with its affiliates, to beneficially own a number of
ordinary shares which would exceed 4.99% or 9.99%, as specified by each selling
shareholder, of our then outstanding ordinary shares following such exercise,
excluding for purposes of such determination ordinary shares issuable upon
exercise of the warrants which have not been exercised. The number of ordinary
shares in the second column does not reflect this limitation. The selling

         OFFER STATISTICS, EXPECTED TIME TABLE AND PLAN OF DISTRIBUTION

        The selling stockholders, which as used herein includes donees,
pledgees, transferees or other successors-in-interest selling ADRs or interests
in ADRs received after the date of this prospectus from a selling stockholder as
a gift, pledge, partnership distribution or other transfer, may, from time to
time, sell, transfer or otherwise dispose of any or all of their ADRs or
interests therein on any stock exchange, market or trading facility on which the
shares are traded or in private transactions. These dispositions may be at fixed
prices, at prevailing market prices at the time of sale, at prices related to
the prevailing market price, at varying prices determined at the time of sale,
or at negotiated prices.

                                       30






        The selling stockholders may use any one or more of the following
methods when disposing of shares or interests therein:

          o    ordinary  brokerage  transactions  and  transactions in which the
               broker-dealer solicits purchasers;

          o    block trades in which the broker-dealer  will attempt 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;

          o    an  exchange  distribution  in  accordance  with the rules of the
               applicable exchange;

          o    privately negotiated transactions;

          o    short sales entered into after the date of this prospectus;

          o    through the  writing or  settlement  of options or other  hedging
               transactions, whether through an options exchange or otherwise;

          o    broker-dealers may agree with the selling  stockholders to sell a
               specified number of such shares at a stipulated price per share;

          o    a combination of any such methods of sale; and

          o    any other method permitted pursuant to applicable law.

        The selling stockholders may, from time to time, pledge or grant a
security interest in some or all of the ADRs owned by them and, if they default
in the performance of their secured obligations, the pledgees or secured parties
may offer and sell the ADRs, from time to time, under this prospectus, or under
an amendment to this prospectus under Rule 424(b)(3) or other applicable
provision of the Securities Act of 1933 amending the list of selling
stockholders to include the pledgee, transferee or other successors in interest
as selling stockholders under this prospectus. The selling stockholders also may
transfer the ADRs in other circumstances, in which case the transferees,
pledgees or other successors in interest will be the selling beneficial owners
for purposes of this prospectus.

        In connection with the sale of our ADRs or interests therein, the
selling stockholders may enter into hedging transactions with broker-dealers or
other financial institutions, which may in turn engage in short sales of the
ADRs or the related common stock in the course of hedging the positions they
assume. The selling stockholders may also sell shares of our ADRs or the common
stock short and deliver these securities to close out their short positions, or
loan or pledge the ADRs or the common stock to broker-dealers that in turn may
sell these securities. The selling stockholders may also enter into option or
other transactions with broker-dealers or other financial institutions or the
creation of one or more derivative securities which require the delivery to such
broker-dealer or other financial institution of the ADRs offered by this
prospectus, which ADRs such broker-dealer or other financial institution may
resell pursuant to this prospectus (as supplemented or amended to reflect such
transaction).

                                       31






        The aggregate proceeds to the selling stockholders from the sale of the
ADRs offered by them will be the purchase price of the ADRs less discounts or
commissions, if any. Each of the selling stockholders reserves the right to
accept and, together with their agents from time to time, to reject, in whole or
in part, any proposed purchase of ADRs to be made directly or through agents. We
will not receive any of the proceeds from this offering. Upon any exercise of
the warrants by payment of cash, however, we will receive the exercise price of
the warrants.

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

        The selling stockholders and any broker-dealers or agents that
participate in the sale of the ADRs or interests therein may be "underwriters"
within the meaning of Section 2(11) of the Securities Act. Any discounts,
commissions, concessions or profit they earn on any resale of the shares may be
underwriting discounts and commissions under the Securities Act. Selling
stockholders who are "underwriters" within the meaning of Section 2(11) of the
Securities Act will be subject to the prospectus delivery requirements of the
Securities Act.

        To the extent required, the ADRs to be sold, the names of the selling
stockholders, the respective purchase prices and public offering prices, the
names of any agents or dealers, any applicable commissions or discounts with
respect to a particular offer will be set forth in an accompanying prospectus
supplement or, if appropriate, a post-effective amendment to the registration
statement that includes this prospectus.

        In order to comply with the securities laws of some states, if
applicable, the ADRs may be sold in these jurisdictions only through registered
or licensed brokers or dealers. In addition, in some states the ADRs may not be
sold unless they have been registered or qualified for sale or an exemption from
registration or qualification requirements is available and is complied with.

        We have advised the selling stockholders that the anti-manipulation
rules of Regulation M under the Securities Exchange Act of 1934 may apply to
sales of ADRs in the market and to the activities of the selling stockholders
and their affiliates. In addition, we will make copies of this prospectus (as it
may be supplemented or amended from time to time) available to the selling
stockholders for the purpose of satisfying the prospectus delivery requirements
of the Securities Act. The selling stockholders may indemnify any broker-dealer
that participates in transactions involving the sale of the ADRs against certain
liabilities, including liabilities arising under the Securities Act.

        We have agreed to indemnify the selling stockholders against
liabilities, including liabilities under the Securities Act and state securities
laws, relating to the registration of the ADRs offered by this prospectus.

        We have agreed with the selling stockholders to keep the registration
statement of which this prospectus constitutes a part effective until the
earlier of (1) such time as all of the ADRs covered by this prospectus have been
disposed of pursuant to and in accordance with the registration statement or (2)
the date on which the ADRs may be sold pursuant to Rule 144(k) of the Securities
Act.

                    EXPENSES ASSOCIATED WITH THE REGISTRATION

        We have agreed to bear all expenses relating to the registration of the
ADRs registered pursuant to the registration statement of which this prospectus
is a part. We estimate these expenses to be approximately US$85,000, which
include the following categories of expenses:

                 FOREIGN EXCHANGE CONTROLS AND OTHER LIMITATIONS

        Australia has largely abolished exchange controls on investment
transactions. The Australian dollar is freely convertible into U.S. dollars. In
addition, there are currently no specific rules or limitations regarding the
export from Australia of profits, dividends, capital, or similar funds belonging
to foreign investors, except that certain payments to non-residents must be
reported to the Australian Cash Transaction Reports Agency, which monitors such
transactions, and amounts on account of potential Australian tax liabilities may
be required to be withheld unless a relevant taxation treaty can be shown to
apply.

The Foreign Acquisitions and Takeovers Act 1975

        Under Australian law, foreign persons are prohibited from acquiring more
than a limited percentage of the shares in an Australian company without
approval from the Australian Treasurer or in certain other limited
circumstances. These limitations are set forth in the Australian Foreign
Acquisitions and Takeovers Act, or the Takeovers Act.

        Under the Takeovers Act, as currently in effect, any foreign person,
together with associates, is prohibited from acquiring 15% or more of our
outstanding shares (or else the Treasurer may make an order requiring the
acquirer to dispose of those shares within a specified period of time). In
addition, if a foreign person acquires shares in our company and as a result the
total holdings of all foreign persons and their associates exceeds 40% in
aggregate without the approval of the Australian Treasurer, then the Treasurer
may make an order requiring the acquirer to dispose of those shares within a
specified time. Under the current Australian foreign investment policy, however,
it is unlikely that the Treasurer would make such an order where the level of
foreign ownership exceeds 40% in the ordinary course of trading, unless the
Treasurer finds that the acquisition is contrary to the national interest. The
same rule applies if the total holdings of all foreign persons and their
associates already exceeds 40% and a foreign person (or its associate) acquires
any further shares, including in the course of trading in the secondary market
of the ADRs.

                                       33






        If the level of foreign ownership exceeds 40% at any time, we would be
considered a foreign person under the Takeovers Act. In such event, we would be
required to obtain the approval of the Treasurer for our company, together with
our associates, to acquire (i) more than 15% of an Australian company or
business with assets totaling over A$5 million; or (ii) any direct or indirect
ownership interest in Australian residential real estate.

        The percentage of foreign ownership in our company would also be
included in determining the foreign ownership of any Australian company or
business in which it may choose to invest. Since we have no current plans for
any such acquisitions and do not own any property, any such approvals required
to be obtained by us as a foreign person under the Takeovers Act will not affect
our current or future ownership or lease of property in Australia.

        Our Constitution does not contain any additional limitations on a
non-resident's right to hold or vote our securities.

        Australian law requires the transfer of shares in our company to be made
in writing. No stamp duty will be payable in Australia on the transfer of ADRs.

website is not part of this prospectus.

        We are an Australian company and are a "foreign private issuer" as
defined in Rule 3b-4 under the Securities Exchange Act of 1934. As a result, (1)
our proxy solicitations are not subject to the disclosure and procedural
requirements of Regulation 14A under the Exchange Act, (2) transactions in our
equity securities by our officers and directors are exempt from Section 16 of
the Exchange Act, and (3) until November 4, 2002, we were not required to make,
and did not make, our SEC filings electronically, so that those filings are not
available on the SEC's website. However, since that date, we have been making
all required filings with the SEC electronically, and these filings are
available over the Internet at the SEC's website at http://www.sec.gov.

                       ENFORCEABILITY OF CIVIL LIABILITIES

        Service of process upon us and upon our directors and officers and the
Australian experts named in this prospectus, most of whom reside outside the
United States, may be difficult to obtain within the United States. Furthermore,
because substantially all of our assets and substantially all of our directors
and officers are located outside the United States, any judgment obtained in the
United States against us or any of such directors and officers may not be
collectible within the United States.

        We have irrevocably appointed Puglisi & Associates as our agent to
receive service of process in any action against us in the state and federal
courts sitting in the City of New York, Borough of Manhattan arising out of this
offering or any purchase or sale of securities in connection therewith. We have
not given consent for this agent to accept service of process in connection with
any other claim.

                 NOTES TO INTERIM CONDENSED FINANCIAL STATEMENTS
                       - in Australian dollars (Unaudited)

1.   Background and Summary of Significant Accounting Policies

Background

Prana Biotechnology Limited ("Prana" or the "Company") was incorporated on 11
November 1997 in Melbourne, Australia and is a development stage enterprise
engaged in the research and development of therapeutic drugs designed to treat
the underlying cause of degeneration of the brain and the eye as the aging
process progresses.

On 28 March 2000, the Company completed its initial public offering in Australia
and listed on the Australian Stock Exchange. In September 2002, the Company's
shares were approved for listing on the Nasdaq SmallCap Market (Code: PRAN).

Financial Reporting Framework

The half-year financial report is a general purpose financial report prepared in
accordance with the requirements of the Corporations Act 2001, Accounting
Standards AASB 1029: Interim Financial Reporting, Urgent Issues Group Consensus
Views and other authoritative pronouncements of the Australian Accounting
Standards Board (herein referred to as "A-GAAP").

It is recommended that this financial report be read in conjunction with the
annual financial report for the year ended 30 June 2003 and any public
announcements made by the Company during the half-year in accordance with
continuous disclosure requirements arising under the Corporations Act 2001.

The accounting policies have been consistently applied by the Company and are
consistent with those applied in the 2003 annual report. Certain information and
footnote disclosures normally included in financial statements prepared in
accordance with A-GAAP have been condensed or omitted. In the opinion of
management, the financial statements reflect all adjustments, which are of a
normal recurring nature, necessary for a fair presentation of the financial
position, results of operations and cash flows of the Company for the interim
periods presented and are not necessarily indicative of a full year's results.

The June 30, 2003 balance sheet was derived from audited financial statements
but does not include all disclosures required by A-GAAP. However, the Company
believes that the disclosures are adequate to make the information presented not
misleading.

Development Stage - Risks and uncertainties

As a development stage enterprise, the Company's prospects are subject to the
risks and uncertainties frequently encountered by companies, which have not yet
commercialised any applications of their technology, particularly in new and
evolving markets. Prana's operating results may fluctuate significantly in the
future as a result of a variety of factors, including capital expenditure and
other costs relating to establishing, maintaining and expanding the operations,
the number and mix of potential customers, potential pricing of future products
by the Company and its competitors, new technology introduced by the Company and
its competitors, delays or expense in obtaining necessary equipment, economic
and social conditions in the biotechnology industry and general economic
conditions.

Prana will continue to review the need to seek additional funding through public
and private financing and/or through collaboration or other arrangements with
corporate partners. The Company cannot be certain that they will be able to
raise any required funding or capital, on favourable terms or at all, or that
they will be able to establish corporate collaborations on acceptable terms, if
at all. If the Company is unable to obtain such additional funding or capital,
they may be required to reduce the scope of their development plans.

Prana's experience in exploiting their technology is limited. The Company cannot
be certain that their operations will be profitable in the short-term, or at
all. If Prana fails in any of their efforts to establish or expand their
business, the results of operations, financial condition and liquidity of the
Company could be materially adversely affected. The Company cannot be certain
that they will be able to obtain or retain any permits required by the Company
to market, sell and deliver its technology. Any of these factors could result in
cessation of Prana's operations.

Significant Accounting Policies

Accounting policies are selected and applied in a manner which ensures that the
resulting financial information satisfies the concepts of relevance and
reliability, thereby ensuring that the substance of the underlying transactions
or other events is reported.

2.   Going Concern

Prana's financial statements are prepared on a going concern basis which
contemplates the realisation of assets and settlement of liabilities and
commitments in the normal course of business. During the six months ended 31
December 2003, the Company incurred a net loss of $4,037,914 and net cash
outflows from operating activities of $2,533,733 and had an accumulated deficit
of $19,617,176. The continuation of the Company as a going concern is dependent
upon its ability to generate sufficient cash from operating and financing
activities. Notwithstanding the net loss and negative cash flow from operations,
the directors consider that the going concern basis of accounting is appropriate
for the following reasons:

     o    as at 31 December 2003 the Company had cash assets of $5,620,156;

     o    the most recently prepared cash flow forecasts  prepared by management
          and  reviewed by the  directors  indicate  that the Company  will have
          sufficient  cash to meet their operating  requirements  until at least
          the date of signing the directors'  declaration for the year ending 30
          June 2004;

     o    as at 10 May 2004 the Company has  19,750,000  share  options on issue
          with an exercise  price of $0.50  which  expire 1 December  2004.  The
          directors  are confident  that a significant  portion of these options
          will be exercised  (which have not been included  within the Company's
          cash flow  forecasts)  on the basis that the  Company  expects to have
          satisfied  a  number  of its  predetermined  scientific  and  business
          milestones during the course of the next six months;

     o    on 28 April  2004 the  Company  announced  to the  market  that it had
          entered into definitive  agreements with new  institutional  investors
          for the purchase of US$20  million of  securities  through the sale of
          four million American  Depositary  Receipts,  or ADR's, at US$5.00 per
          ADR. These agreements also involve the acquisition by the investors of
          five-year warrants to purchase an additional three million ADR's at an
          exercise price of US$8.00 per ADR. If exercised,  these warrants would
          raise an additional US$24 million for the Company. The transaction was
          subject to shareholder approval that was obtained 1 June 2004; and

     o    the Company has  consistently  raised capital as and when required for
          its operations and anticipates that it will remain in a position to do
          so in the future.

3.   Dividends

The Company resolved not to declare any dividends in the six month period ended
31 December 2003.

4.   Segment Information

The Company's activities are predominately within Australia and cover research
into Alzheimer's Disease and other major age-related degenerative disorders.

5.   Contingent Liabilities

There has been no change in contingent liabilities since the last annual
reporting date.

6.   Events Subsequent to Reporting Date

Other than as already disclosed in the financial statements, there have been no
events after reporting date that have a material effect on this report.

7.   Reconciliation to US GAAP

The financial statements have been prepared in accordance with A-GAAP, which
differ in certain significant respects from accounting principles generally
accepted in the United States of America ("US GAAP"). The following is a summary
of the adjustments to net loss and total equity required when reconciling such
amounts recorded in the financial statements to the corresponding amounts in
accordance with US GAAP, considering the differences between A-GAAP and US GAAP.

                        (A Development Stage Enterprise)

a.   Share-based compensation

      Options issued to consultants for services rendered

      The Company issued 532,500 and 400,000 share options to outside
      consultants during the half years ended 31 December 2003 and 31 December
      2002, respectively. The options were issued under the Employee Share
      Incentive Scheme as a reward for services rendered or in consideration for
      services rendered to the Company. Under A-GAAP, the Company did not
      recognise any compensation expense. Under US GAAP, the options issued to
      the outside consultants are accounted for under Statement of Financial
      Accounting Standards 123: Accounting for Stock Based Compensation ("SFAS
      123") and Emerging Issues Task Force Issue 96-18: Accounting for Equity
      Instruments That Are Issued to Other Than Employees for Acquiring, or in
      Conjunction with Selling, Goods or Services ("EITF 96-18"). Accordingly,
      the Company has calculated compensation cost based on the estimated fair
      value of the options measured on the date the services were completed by
      the respective consultants, using the Black-Scholes model with the
      following weighted average assumptions:

     o    risk-free  interest  rate of 4.73% to 5.24% for 31  December  2003 and
          4.47% for 31 December 2002;

     o    no dividends;

     o    expected  volatility  of 20.60% to 26.30% for 31 December 2003 and 48%
          for 31 December 2002; and

     o    expected life of two years.

      Options issued to employees for services rendered

      The Company issued 764,667 and 158,274 share options to employees under
      the Employee Share Incentive Scheme as a reward for services rendered to
      the Company during the half year ended 31 December 2003 and 31 December
      2002.Under A-GAAP, no compensation cost has been recognised in respect of
      the share options issued by the Company. Under US GAAP, the Company has
      elected to account for the issuance of share options to the employees in
      accordance with Accounting Principles Board Opinion 25: Accounting for
      Stock Issued to Employees and related interpretations ("APB 25"). Under
      APB 25, compensation cost is recognised to the extent that the quoted
      market price of the stock exceeds the exercise price of the options at the
      grant date, and is charged to operations ratably over the vesting period.

      The adjustment also includes the vesting period amortisation of
      compensation cost attributable to share options issued to employees in
      prior periods for which the quoted market price exceeded the exercise
      price of the options at the grant date.

      Shares issued to consultants for services rendered

      The Company issued 70,768 and 28,868 shares to outside consultants in
      consideration for services rendered to the Company during the half year
      ended 31 December 2003 and 31 December 2002, respectively. Under A-GAAP,
      the Company recognised compensation expense based on the director's
      valuation of the shares issued. Under US GAAP, the shares issued to the
      outside consultants are accounted for under SFAS 123 and EITF 96-18.
      Accordingly, compensation cost is based on the quoted market price of the
      shares measured on the date the services were completed by the respective
      consultants.

b.   Intangible assets

     Under A-GAAP, the Company capitalised costs associated with the acquisition
     and development of core intellectual property (primarily patents) until
     December 1999. Such costs are amortised on a straight-line basis over the
     estimated useful lives of 15 years. In December 1999, the directors
     revalued the intangible assets upwards by $14,661,942 and recorded the
     revaluation in the asset revaluation reserve in equity. The increased asset
     value resulted in additional amortisation for periods subsequent to the
     revaluation. All costs associated with the acquisition and development of
     core intellectual property incurred subsequent to the December 1999
     revaluation are expensed as incurred under A-GAAP.

     For US GAAP purposes, the Company capitalises costs associated with the
     acquisition of patents and other core intellectual property, legal costs
     associated with successful patent defences and successful patent
     applications. Such costs are amortised on a straight-line basis over the
     estimated useful lives of 15 years. All other costs associated with patents
     and other core intellectual property are expensed as incurred. Upward
     revaluations of intangible assets are not allowed under US GAAP (except in
     connection with a purchase business combination).

c.   Deferred tax effect of US GAAP adjustments

     The deferred tax effect of US GAAP adjustments is nil because it is more
     likely than not that the net deferred tax asset will not be realized, and
     accordingly, the Company has recorded a 100% valuation allowance against
     the net deferred tax asset.

d.   Other

      Under A-GAAP, interest income is reported as a component of revenue from
      ordinary activities. Under US GAAP, interest income is reported as a
      component of non-operating income.

      Under A-GAAP, amortisation of intangible assets used in research and
      development projects is reported in depreciation and amortisation expense.
      Under US GAAP, amortisation of intangible assets used in research and
