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 any of our product candidates,products, including our newcurrent lead product candidate, PBT-2, to market or generate revenues from itstheir commercial application. We cannot makeOur current or any assurances that any of ourfuture product candidates, if successfully developed, willmay not 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 with Schering A.G., a major international pharmaceutical company, and Neurosciences Victoria Ltd., a consortium of Australian universities, research institutes and teaching hospitals, under which Schering A.G. will provide to us funding of up to A$2.7 million for specified research and development projects that we will conduct, including the development of a new Alzheimer's diagnostic, we cannot make any assurances that we will
We may not 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 theThe projects initially specified in connection with any such collaboration or theand any associated funding, by Schering A.G. will notmay change or discontinue with the changing interests of either Schering A.G.the collaborator or Prana, or thatus, and any such change may change the budget for the projects under the collaboration. We are also unable to assure you thatAdditionally, our research willmay not lead to the discovery of additional product candidates, or thatand any of our current and future product candidates willmay not 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 theThe products we develop willmay not 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,the development of PBT-2 or any future pharmaceutical product will be completed or commercialized, whether funded by us, as part of a collaboration or through a grant.
We may need to prioritize the development of our most promising candidates at the expense of the development of other pharmaceuticalproducts.
We may need to prioritize the allocation of development funds towards what we believe to be our most promising products. The nature of the drug development process is such that there is a constant availability of new information and data which could positively or adversely affect a product in development. We cannot predict how such new information and data may impact in the future the prioritization of the development of our current or future product candidates or that any of our products, underregardless of its development stage or the investment of time and funds in its development, will continue to be commercialized. funded or developed.

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 may not have sufficient financial resources available to us or 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:
·the continued progress of our research and development programs;
·the timing, scope, results and costs of pre-clinical studies and clinical trials;
·the cost, timing and outcome of regulatory submissions and approvals;
·determinations as to the commercial potential of our product candidates;
·our ability to successfully expand our contract manufacturing services;
·our ability to establish and maintain collaborative arrangements; and
·the status and timing of competitive developments.
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. However, such additional financing may not 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 will not be able to commercialize PBT-2 or any of ourfuture 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. 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. 4
5

We cannot make any assurances that we willmay not be able to undertake further clinical trials of PBT-1 or commence clinical trials of PBT-2 orand any future product candidate, including one that may emerge from our proposed vaccine as planned,program, or to demonstrate the safety and efficacy or superiority of PBT-1 or PBT-2any of these product candidates over existing therapies or other therapies under development, or enter into any collaborative arrangement to commercialize PBT-1our current or PBT-2future product candidates on terms acceptable to us, or at all. In April, 2005, we ceased clinical trials of our PBT-1 compound in Alzheimer’s disease and we may not be able to undertake future clinical trials of PBT-1 in the future. 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.
·government or regulatory delays, including delays in obtaining approvals from applicable hospital ethics committees and internal review boards;

·slower than expected patient recruitment;

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

·unforeseen safety issues; and

·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 delayswith our product candidates. Delays in manufacturing sufficient quantities of PBT-1 or PBT-2such materials to the required standards for pre-clinical and clinical trials may negatively impact our business and operations.
We cannot make any assurances that we willmay not be able to manufacture sufficient quantities of PBT-1, PBT-2 or any of our otherfuture product candidates (including PBT-1) 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. 5
We may be required to enter into contracting arrangements with third parties to manufacture PBT-1, PBT-2 and our otherany future product candidates for large-scale, later-stagepreclinical and/or clinical trials. We cannot make any assurances that we willmay not be able to make the transition from laboratory-scale to development-scale, or from development-scale 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 willmay not 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 willmay not 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. Although we believe that our existing cash and cash equivalents and revenue resources will be adequate to satisfy the requirements of our current and planned operations for the foreseeable future, we cannot make any assurances that such funds will be available or 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. 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 required to design and develop new synthetic pathways for most, if not all, of the products that we currently intend to develop. We can not predict the success of such efforts, the purity of the products that may be obtained or the nature of the impurities that may result from such efforts. If we are not able 6 to establish new strategic alliancesobtain an acceptable purity for any product candidate or other arrangements with corporate partners onan acceptable terms, or at all. Any shortfall in funding could result in our having to curtail our operations, including our researchimpurity profile, pre-clinical and development activities,clinical trials would be delayed, which could have a material adverse effect on the priority of the development of our product candidates, our business, financial condition and results of operations.
We are dependent upon a sole supplier of our lead compound, PBT-2, and could incur significant costs and delays if we are unable to promptly find a replacement.
We typically rely on a single manufacturer to develop Good Manufacturing Practice (GMP) synthetic processes for our lead compounds. Our lead compound, PBT-2, is manufactured by the Institute of Drug Technology Limited and we relied on Orgasynth Industries to manufacture our PBT-1 compound prior to ceasing its clinical trials for Alzheimer's disease in April 2005. We intend to continue these relationships and this approach with further compounds if it remains financially viable. We have not had any prior manufacturer of our compounds elect to cease its relationship with our company. We may not be able to promptly find a replacement manufacturer, if required, without incurring material additional costs and substantial delays.
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$25,008,597, A$9,885,614 A$4,585,838 and A$5,448,4674,584,838 during the fiscal years ended June 30, 2005, 2004, 2003 and 2002,2003, respectively. As of June 30, 2004,2005, our accumulated deficit was A$25,464,876.50,473,473. We cannot assure you that we willmay not be able to achieve or maintain profitability.

Our success depends upon our ability to protect our intellectual property and our proprietary technology. Our
Any future 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.
·obtain and maintain patents to protect our own products;

·obtain licenses to the patented technologies of third parties;

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

·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 anyAny of the pending or future patent applications filed by us or on our behalf willmay not be approved, or that we willmay not 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 could be required to pay damages, alter our products or processes, obtain licenses or cease certain activities. We cannot be certain that the licensesLicenses required under patents held by third parties wouldmay not 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. 7
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, regardlessWe may have to defend the validity of outcome, could be expensive and time consuming, and adverse determinationsour patents in any such proceedings could prevent us from developing, manufacturingorder to protect or commercializingenforce our products and could haverights against 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 party. Third parties have in the past and may in the future 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. While defending our patents, the scope of the claim may be reduced in breadth and inventorship of the claimed subject matter, and proprietary interests in the claimed subject matter may be altered or reduced. 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.
8

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 Controland Heathcare Products Regulatory Agency, or MHRA, in the United Kingdom and the European Medicines Evaluation Authority.Authority, or EMEA. 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 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 AgencyMHRA 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 willmay not 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 or consultancy 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 willmay not 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 8 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, EMEA, MHRA and other regulatory approvals.
9

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 PBT-2 product candidates.candidate. 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.
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
Our current or future products willmay not achieve market acceptance even if they are approved by the TGA, and the FDA.FDA or any other regulatory authority. The degree of market acceptance of oursuch 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.
·the receipt and timing of regulatory approvals for the uses that we are studying;

·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

·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 9 any assurances that qualifiedQualified personnel willmay not be available in adequate numbers or at a reasonable cost, thatcost. Further, additional financing willmay not be available on acceptable terms, or at all, or thatand our sales staff willmay not 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 willmay not be able to enter into marketing arrangements with any marketing partner or that if such arrangements are established, our marketing partners willmay not 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.
10

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 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 recentfor the PBT-1 clinical trial and extension study and the PBT-2 clinical trials and intend to obtain similar coverage for future clinical trials. We cannot be certain that suchSuch coverage willmay not 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 willWe may not be able to obtain product liability insurance in the event of the commercialization of a 10 product or that it willsuch insurance may not 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
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 Securities
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. TheDuring the last two fiscal years, the market price for our ordinary shares on the Australian Stock Exchange has ranged from as low as A$0.4350.13 to a high of A$2.39 during the last two fiscal years1.18 and the market price of our American Depositary Shares on the NASDAQ Capital Market has ranged from as low as US$2.950.98 to a high of US$12.80 since our listing on the NASDAQ SmallCap Market on September 5, 2002 and until June 30, 2004.10.50. The market price for our ordinary sharessecurities 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 annual report, 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; 11 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.
·the results of pre-clinical testing and clinical trials by us and our competitors;

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

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

·determinations regarding our patent applications, patents and those of others;

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

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

·litigation;

·economic and other external factors; and

·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.
New corporate governance regulations could increase the cost of our operations operations.
As a result of recent corporate governance scandals and the legislative and litigation environment resulting from those scandals, the costs of being a public company in general have increased. The Sarbanes-Oxley Act of 2002 requires changes in some of our corporate governance and securities disclosure or compliance practices. We expect that the on-going implementation of these regulations will further increase our legal compliance costs and will make some activities more time consuming. We are presently evaluating and monitoring regulatory developments and cannot estimate the magnitude of additional costs we may incur as a result of such developments. The implementation of Section 404 of the Sarbanes-Oxley Act of 2002, which governs internal controls and procedures for financial reporting, will require us to expend significant management time and financial resources to comply with the applicable requirements. This and other proposed legislation may increase the fees of our professional advisors and our insurance premiums.
12

Our accounting staff will need to be trained on the application of U.S. GAAP and the Securities and Exchange Commission accounting requirements.
Our management has concluded that our company has insufficient accounting personnel that have sufficient knowledge and experience in U.S. GAAP and the Securities and Exchange Commission accounting requirements. The accounting personnel who prepare our financial statements will need to be trained on the application of U.S. GAAP accounting pronouncements and standardized reconciliation templates will need to be improved to assist in the reconciliation process between A-GAAP and U.S. GAAP. If the accounting personnel who prepare our financial statements are not adequately trained, our disclosure may be deficient and could result in a material misstatement to our annual or interim financial statements.
There is a substantial risk that we are a passive foreign investment company, or PFIC, which will subject our U.S. investors to adverse tax rules.
Holders of our ordinary shares or American Depositary SharesADRs who are U.S. residents face adverse income tax consequences.risks. There is a substantial risk that we will be classified asare a passive foreign investment company, orcommonly referred to as 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 SharesADRs and would likely cause a reduction in the value of such shares.ADRs.  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 assetscash is considered to be an asset, which produceproduces passive income. As a result of our substantial cash position which may increase if a substantial portionand the decline in the value of our outstanding options are exercised, there isstock, we believe that we became a riskPFIC in 2004 under a literal application of the asset test described above, that we will be declared a PFIC inwhich looks solely to the event the price of our ordinary shares declines substantially.market value.  If we were determined to beare classified as a PFIC for U.S. federal income tax purposes, highly complex rules would apply to U.S. holdersowning ordinary shares.ADRs.  Accordingly, you are urged to consult your tax advisors regarding the application of such rules. However, becauseUnited States residents should carefully read “Item 10E. Additional Information - Taxation, United States Federal Income Tax Consequences” for a more complete discussion of the determination of whether we are a PFIC is based upon the compositionU.S. federal income tax risks related to owning and disposing of our income and assets from time to time, this determination can not be made with certainty until the end of the calendar year. 12 ADRs.

We do not anticipate paying dividends on our ordinary shares.
We have never declared or paid cash dividends on our ordinary shares and do not expect to do so in the foreseeable future. The declaration of dividends is subject to the discretion of our Board of Directors and will depend on various factors, including our operating results, financial condition, future prospects and any other factors deemed relevant by our board of directors. You should not rely on an investment in our company if you require dividend income from your investment in our company. The success of your investment will likely depend entirely upon any future appreciation of the market price of our ordinary shares, which is uncertain and unpredictable. There is no guarantee that our ordinary shares will appreciate in value or even maintain the price at which you purchased your ordinary shares.

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. All but twoMost of 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.

Our mission is to develop therapeutic drugs designed to treat the underlying causes of degeneration of the brain and the eye as the aging process progresses, initially focusing on Alzheimer'sAlzheimer’s disease. Other potential applications for our therapies include age-related cataracts, Creutzfeldt-Jakob disease (the human variant of Mad Cow disease), Motor NeuronHuntington’s disease and Parkinson'sParkinson’s disease. Our technology is the outcome of many years of intense research from some of the leading scientists in the world in the area of age-related degenerative diseases.
Since completing our initial public offering and listing process on the ASX on March 28, 2000, we have concentrated our resources toward the pursuit of our diseases targets and in particular the progressdisease targets. Initially we focused on clinical trials of our clinical trial for PBT-1 compound as a successful therapeutic for the treatment of Alzheimer'sAlzheimer’s disease. We commenced our planned phase II human clinical trial for PBT-1 in August 2000 at the Mental Health Research Institute and the Royal Melbourne Hospital. The 36 week trial was completed in January 2002 and in April 2002, Professor Colin Masters, Chairman of our Scientific Advisory Board, reported at the Seventh International Geneva/Springfield Symposium on Advances in Alzheimer Therapy in Geneva that the trial had demonstrated a significant slowing in the rate of progression of cognition (as measured by the ADAS-cog score) in patients with initial ADAS-cog scores of 25-40. Professor Masters presented that this provided encouraging proof of concept for PBT-1 and the (beta)Amyloid theory of Alzheimer's disease. The results were published in the Archives of Neurology in December 2003.2002. All patients from this study were then provided the opportunity to roll into a further 48 week extension study. A complete set32 out of 36 patients completed the initial trial, out of which 27 patients elected to start the extension study and 18 patients completed the full 84-week study. On October 12, 2004, we announced the results from thisof the open label 84-week “Extension Study” of our Phase II clinical trial of PBT-1. On October 18, 2004, we announced plans to pursue a Phase II/III study have yetto examine the effect of PBT-1 in moderate to severe Alzheimer’s disease patients in the second quarter of 2005, to be published however speaking atknown as the eighth International Springfield/Montreal Symposium on AdvancesPLACQUE (Progression Limiting in Alzheimer's disease, Professor Masters was able to report that extended use of PBT-1 appears relatively well tolerated and appears to provide continued effectiveness in slowing the progress of cognitive function associated with Alzheimer's disease. In early August 2003,Alzheimer’s: Clioquinol’s Efficacy) study. On April 11, 2005, we announced that we would not proceed with the PLACQUE study and that we had re-evaluated our further work on the PBT-1 program. As part of our effort to manufacture Good Manufacturing Practice (GMP) grade PBT-1 clinical trial material, we characterized the various impurities that occur in the synthetic process and found unacceptably high levels of a di-iodo-8-hydroxyquinoline impurity that could potentially increase the risk of side-effects and mutagenicity. We considered methods to reduce the levels of the di-iodo impurity, however, we reached the conclusion that attempts to reduce the impurity to safe levels were not likely to be successful in a timely, commercially viable manner and that further development of PBT-1 for the treatment of Alzheimer’s disease was not appropriate. As a result of these events, we proceeded to conduct a strategic review of our pending strategic development programs. 
15

On June 16, 2005, we announced that we had completed a review of our strategic development programs and we reaffirmed our commitment to our lead candidate for the potential treatment of Alzheimer's disease, PBT-2. Unlike PBT-1, PBT-2 has a structure that does not contain iodine and is therefore not capable of forming the di-iodo impurity that has been associated with mutagenicity. PBT-2 was announced as a new lead metal protein attenuating compound, or MPAC, molecule for Alzheimer'sAlzheimer’s disease designated as PBT-2 that had been selected for development.in early August 2003. PBT-2 is the result of rational drug design. It has been built "from“from the ground up"up” to fulfill very specific criteria. It was designed so that it will have no patent ambiguities, be orally bioavailable and cross the blood brain barrier. PBT-2 has beenwas selected from over 300 Prana-developed compounds that had been developed by us at such time and has demonstrated significantly greatersignificant effectiveness in both pre-clinical in-vitroin vitro and in-vivoin vivo testing and has been designed to have an improved safety and efficacy profile compared to PBT-1. In February 2004, Prana waswe were awarded a second research and development START grant of A$1.35 million to take PBT-2 through safety testing and Phase I clinical trials for Alzheimer's disease, PBT-2 is progressing through formaldisease. Formal preclinical toxicology testing for PBT-2 has been completed and is expectedin March 2005, we commenced a series of Phase I clinical trials at a facility associated with the Utrecht University Hospital in Utrecht, the Netherlands. On November 7, 2005, we announced the successful completion of the Phase I trial for PBT-2, a double blind, placebo-controlled single dose escalation study, conducted on 55 healthy, male volunteers between the ages of 18 and 50, which was designed to be readyevaluate the safety, tolerability and pharmacokinetics of PBT-2. Data from the study shows that PBT-2 was well tolerated with little difference in the incidence of adverse events between those receiving PBT-2 and those receiving the placebo. Additionally, the pharmacokinetic analysis demonstrated that the drug exposure increased predictably and in a linear manner, both of which are strong characteristics for human trialinga central nervous system drug. Concurrent findings in earlya pre-clinical mouse model indicate that PBT-2 passes into the brain of mice more extensively than its predecessor, PBT-1. We have also completed three out of four stages of our second Phase I clinical trial, a multi-dose escalation safety clinical trial of PBT-2 in elderly, healthy, male and female volunteers. We anticipate completing the final dosing stage in December 2005. 14 In addition, the preclinical toxicology studies and GMP manufacturing development required for Phase II and Phase III clinical studies of PBT-2 are concurrently underway.
In March 2003, we announced our first major licensing and research collaboration with Schering A.G., or Schering, a major international pharmaceutical company, and Neurosciences Victoria Ltd., or NSV, an organization of the Universities of Melbourne and Monash, established to promote, commercialization of discoveries emanating from Victoria, Australia universities and medical research institutes. Under such collaboration, we appointed NSV to act as our agent for the purpose of receipt of funding from Schering for certain specified research and development projects that we will conduct and to facilitate the licensing of intellectual property arising from such projects to Schering, all under the terms of a separate research and collaboration agreement between Schering and NSV. Among otherThese projects we will concentrate onwere designed to investigate the developmentpossibility of a new Alzheimer's diagnostic. We are seeking to develop the first highly reliableuse of MPACs and similar compounds as diagnostic markers for Alzheimer's disease using brain imaging of specific compoundsAlzheimer’s disease. Although these studies demonstrated brain penetration of particular MPACs, they did not support further exploration of MPACs as markers to measure the debilitating amyloid deposits. Under thediagnostic markers. The parties concluded this collaboration Schering is providing to us fundingas of up to A$2.7 million over the life of the projects, with additional milestone payments and royalties from discoveries. While Schering has focused its Alzheimer's disease development efforts at diagnostics and imaging, this funding will allow discovery research for additional therapeutic and diagnostic targets and technologies. June 30, 2005.

We have also identified and provisionally patentedfiled an international patent application directed to a novel target for an Alzheimer's disease vaccine. The Commonwealth Government of Australia provided us with a A$227,252 Biotechnology Innovation Fund, or BIF grant for the initial proof of concept stage of this research. The research under this BIF grant finished at the end of January 2005 following the completion of project milestones stipulated in the grant, demonstrating that a mouse could generate antibodies that preferentially recognize dimerized βAmyloid. We are currently collaboratingnegotiating a contract with Prima Biomed Ltd., anotheror Prima, an Australian biotechnology company publicly traded Australian biotech company, as well ason the ASX (ASX: PRR), to undertake the characterization and scale-up of prospective antibody candidates that were identified during the initial proof of concept stage for testing in future passive vaccine trials in Alzheimer's disease model mice. We will be utilizing the resources of Prima, the Austin Research Institute, the University of Melbourne and the Mental Health Research Institute to pursue this therapeutic approach. The research is investigating the feasibility of developing a vaccine to prevent the onset or progression of Alzheimer's. The research will assess the ability of the immune system to selectively produce specific antibodies which target the "toxic linked"“toxic linked” forms of beta amyloid (not `normal' beta amyloid) associated with the pathology of theAlzheimer’s disease, as an effective Alzheimer's treatment. The Commonwealth of Australia government has provided a A$227,252 Biotechnology Innovation Fund, or BIF, granttreatment for this work. the disease.
Since inception, we have not been required to invest material amounts for capital expenditures since our development efforts have taken place at research facilities operated by institutions with whom we have relationships. In the three fiscal years ended June 30, 20042005 our capital expenditures have totaled A$272,980.272,757. We have not incurred any material capital expenditures since July 1, 2004. 2005.
B. BUSINESS OVERVIEW Prana'sBusiness Overview
Prana’s Background
Medical science has made a significant number of breakthroughs over the past century. The average life span in western cultures has substantially increased. The diseases associated with aging have, however, yet to be fully understood or effectively treated. It is now believed that a number of age-related diseases may be capable of being treated.
Our platform technology was developed over a period of many years with the financial support of various institutions and from various grants. The majority of these funds were directed at research into Alzheimer's disease, however the outcomes demonstrated by this research have created strong implications for other age-related degenerative disorders where the 15 pathology of the disease is based on the inter-relationship between metals and proteins. Published studies Positive effects of clioquinol (the compound which provided us with our proof-of-concept for metal protein attenuating compound, or MPAC, action in Alzheimer’s disease, or PBT-1) have now been publishedin animal models of Parkinson'sParkinson’s disease have reported positive effects of the lead compound PBT-1 and Huntington’s disease. These findings continue to strengthen the "theory“theory of metal related toxicity"toxicity” in many neurodegenerative diseases and continue to provide evidence supporting our position that MPACs will be a useful therapeutic in a variety of neurodegenerative diseases. There is currently no cure or prevention for Alzheimer's disease nor any successful cure for any of the principal forms of neuron-generatingneurodegenerative diseases which comprise our disease targets.
17

The protein believed to be involved in Alzheimer's disease is (beta)Amyloid.βAmyloid. Very little was known about (beta)AmyloidβAmyloid protein until 1984 when Professors Colin Masters, Konrad Beyreuther and the late Dr. Glenner sequenced the chemistry of the protein which has since become the dominant focus world-wide of Alzheimer'sAlzheimer’s disease research.
In 1987, Drs.Professors. Masters and Beyreuther and Professor Rudolph Tanzi of Harvard Medical School discovered how (beta)AmyloidβAmyloid was produced and in 1994 Professor Ashley Bush of Harvard Medical School discovered that the interaction between metals and (beta)AmyloidβAmyloid is associated with the toxicity seen in Alzheimer'sAlzheimer’s disease, hopefully paving the way for the development of therapeutic drugs to treat the disease.
Our intellectual property has been developed over an extended period through the collaborative efforts of highly regarded scientists and research institutions in this field.
Research Institutions
The intellectual property owned by our company has been developed at several internationally recognized institutional research facilities: o The Massachusetts General Hospital, Genetics and Aging Unit in Boston. Massachusetts General Hospital is the largest teaching hospital for Harvard Medical School; o The University of Melbourne, Department of Pathology; and o The Biomolecular Research Institute in Melbourne.
·The Massachusetts General Hospital, Genetics and Aging Unit in Boston. Massachusetts General Hospital is the largest teaching hospital for Harvard Medical School;
·The University of Melbourne, Department of Pathology;
·The Mental Health Research Institute; and
·The Biomolecular Research Institute in Melbourne.
Work conducted at the first two of these institutions identified an initial preferred compound, clioquinol, codenamed PBT-1, which was used in our phasePhase II human clinical trials. Our research program also aims to find further and potentially more effective preferred compounds for the treatment of Alzheimer'sAlzheimer’s disease as well as for our other major disease targets.indications (such as Parkinson’s disease and Huntington’s disease). These efforts have lead to the development of PBT-2, a small molecular weighed chemical entity that demonstrates a significant improvement over PBT-1 and a portfolio of almost 400 other MPAC molecules. Initially concentrating on the development of novel MPAC within the same chemical class as PBT-1, PBT-2, a low molecular weight chemical entity that demonstrates a significant preclinical improvement over PBT-1, and a portfolio of approximately 400 MPAC molecules in total (approximately 300 of which are of the successful designsame chemical class as PBT-1 and synthesisthe remaining MPACs are of PBT-2 the chemistry towards the synthesis of novel MPACs has now expanded to include multiple other chemical classes. classes).
PlatformTechnology and Research Programs
We regard our intellectual property as a "platform technology"“platform technology” since we believe that it addresses the causes of a broad spectrum of age related diseases based on the interrelationship of metals and proteins. The most advancedTo date, the majority of our research aimedefforts have been directed at our disease targets is itsresearch into potential 16 therapeutics for the treatment of Alzheimer'sAlzheimer’s disease. However,Recent published data together with our initial findings have provided strong indications that the pathology for other certain age-related and degenerative disorders may also be based on the inter-relationship between certain metals and proteins, and we believe that the platform technology may also be applicable for: o Age-related cataracts; o Creutzfeldt-Jakob
18

·Age-related cataracts;
·Parkinson’s disease;
·Huntington’s disease;
·other neurodegenerative diseases.
Alzheimer’s Disease. Research is ongoing to increase our understanding of the neuropathology of Alzheimer’s disease. Our research continues to focus on the structure and function of β-amyloid and its precursor, and protein structural studies specifically around the sites of interaction between metals, metal complexes and our MPACs and the significant proteins in Alzheimer’s disease (CJDsuch as APP and b-amyloid. PBT-2 has completed the initial formal preclinical toxicology testing required to support initial human trials and in March 2005, we commenced a series of Phase I clinical trials, at a facility associated with the Utrecht University Hospital in Utrecht, the Netherlands. On November 7, 2005, we announced the successful completion of the first Phase I trial for PBT-2. We have also completed three out of four stages of a second Phase I clinical trial, a multi-dose escalation safety clinical trial of PBT-2 in elderly, healthy, male and female volunteers. We anticipate completing the final dosing stage in December 2005. In addition, the preclinical toxicology studies and GMP manufacturing development required for Phase II and Phase III clinical studies of PBT-2 are concurrently underway. We can give no assurance that the Phase I trial will be completed or Mad Cow disease); o Motor Neuron disease;prove to be successful, or that further trials will be initiated with PBT-2, or if initiated that they will be completed or prove to be successful.
The research and o development projects under our licensing and research collaboration with Schering A.G. and Neurosciences Victoria Ltd. concentrated on the development of a new Alzheimer’s diagnostic. These projects were designed to investigate the possibility of MPACs and similar compounds being used as diagnostic markers for brain imaging of Alzheimer’s disease. Although these studies demonstrated brain penetration of particular MPACs, they did not support further exploration of MPACs as diagnostic markers. The parties concluded this collaboration as of June 30, 2005.
Age-Related Cataracts. Basic research in the area of age related cataracts is being conducted by several independent groups of researchers around the world. Data to date indicate that some age-related cataracts contain the same protein aggregation as that seen in Alzheimer’s disease. Preliminary animal data suggests that the deposition of some proteins in age related cataracts may be related to the inappropriate interaction of metals and amyloid species. At present, we are not undertaking active research in this area, although through the close ties with Professor Masters and the University of Melbourne, we retain the ability and opportunity to investigate the usefulness of its MPAC portfolio in treating and/or preventing age-related cataracts, if and when additional evidence arises to prioritize this opportunity. We can give no assurance that such research will continue or if continuing will be successful.
19

Parkinson's Disease. Parkinson’s disease is another crippling disease of the aging population. It causes a progressive slowing of movement, tremor and the loss of fine motor control. Increasingly, dementia is being recognized as a significant component of Parkinson’s disease. Existing therapies may provide some short term symptomatic relief but do not address the underlying cause of the disease. We believe that our platform technology may affect the aggregation of the proteins concerned and may provide a pathway for reversing the disease. Parkinson’s disease is believed to affect 150 people per 100,000 or 2.5% of persons over the age of 85. It has been reported that approximately four million people suffer from Parkinson’s disease worldwide.
Our Melbourne research team is working on the key protein (alpha-synuclein) that aggregates to form the diagnostic marker of this disease. We believe that the aggregated form of this protein is susceptible to the same therapeutic strategy that is being used for Alzheimer’s disease, and laboratory tests are in progress to confirm this approach. The molecules already developed as part of the Alzheimer’s disease program are being tested and validated as prospective agents for the treatment of Parkinson’s disease, together with agents arising from the current chemistry synthetic program. Experimental animal models are being developed and integrated into the rationale drug design screening regime. During 2005, we entered into a contractual arrangement with the Integrative Neuroscience Facility based at the Howard Florey Institute in Melbourne to assist in the examination of the effect of MPACs administered to the 6-hydroxydopamine (PD) mouse model. Recent published data from groups unrelated to us have demonstrated the usefulness of clioquinol in treating the symptoms of Parkinson’s disease generated in preclinical models of the disease. These results, although yet to be repeated, provide further support to our position that MPACs (clioquinol and others) may provide a useful treatment in Parkinson’s disease patients.
Huntington's Disease. Huntington’s disease is a crippling genetic neurodegenerative disorder of the central nervous system caused by a mutation in a gene which encodes the huntingtin protein. The disease results in progressive deterioration of physical, cognitive and emotional abilities that lead to severe incapacitation and eventually death, generally 15-25 years after the onset of the disease. Huntington's disease primarily affects adults, usually between the ages of 30 and 50.
U.S.-based researchers recently presented the effects of clioquinol in an animal model of Huntington’s disease, showing evidence of improved behavior, motor skills and inhibition of the abnormal form of the huntingtin protein. Based on these findings, we are currently testing our proprietary MPACs in collaboration with researchersbased atthe Veterans Affairs Medical Center and the Department of Neurology, University of California, San Francisco, under a collaborative research agreement.
Clinical Trials Having
In 2000, having demonstrated the effectiveness of PBT-1 in the laboratory, we received official Ethics Committee approval from the Royal Melbourne Hospital, Victoria, Australia, to test PBT-1 in human subjects. Phase II human clinical trials for PBT-1 commenced during August 2000 and were completed in January 2002 and an academic paper outlining the findings was published in the peer reviewed journal Archives of Neurology in December 2003. The clinical trials were conducted principally at our sponsored facilities at the Royal Melbourne Hospital and the Mental Health Research Institute, both based in Melbourne. Prescribed dosages of our preferred compoundclioquinol, or PBT-1 (our prototype MPAC selected to develop proof-of-concept) were administered to 50% of the study candidates, the other 50% received a placebo. The trial, isknown as PBT1-011 AD,was a "double blind trial" so neither the administrating medical personnel nor the patients involved in the trial process were aware of who received PBT-1 and who received the placebo. All subjects were asked to perform various prescribed cognitive tests to determine if the introduction of PBT-1 had a demonstrable effect as compared to those subjects receiving the placebo. On completion of the initial 36 weeks of dosing, all subjects were invited to continue into an extension arm wherestudy, during which they received treatment with PBT-1 for an additional 48 weeks.
20

The trial was performed to contemporary "best practice"“best practice” clinical trial standards. PranaWe contracted Kendle Pty Ltd., or Kendle, to manage the clinical trials, ensuring compliance to the required international standards of Good Clinical Practice as set out by the International Conference on Harmonisation.Harmonization. These protocols provide strict guidelines for the performance of clinical trials in an ethical and scientifically soundacceptable manner, and are mandatory for applications to international regulatory authorities for market access.
The Institutional Ethics Committee overseeing the trial carefully addressed safety concerns as follows: o The dose of clioquinol to be used in the clinical trial is below the dose previously recommended for use as a short term antidiarria agent. All patients commenced on 250 mg per day, increasing to a maximum of 750 mg per day. o The underlying biochemical mechanism associated with clioquinol toxicity is not fully understood. Recent work suggests that clioquinol may alter absorption and/or renal excretion of Vitamin B12. All patients in the study received supplementary Vitamin B12. o The trial protocol required close monitoring of all patients by a safety committee of clinical experts. This committee independently monitored all 17 patient data including laboratory results and neurological test results on a regular basis

In April 2002, Professor Masters reported that the trial achieved its targeted benchmarks and that the two major initial findings of the study were: o The (beta)Amyloid protein, which was a target of the activity of PBT-1, was significantly reduced in the blood of mild to moderate patients in the treatment group compared to an increase in the placebo group; and o The progression of Alzheimer's
·The βAmyloid protein, which was a target of the activity of PBT-1, was significantly reduced in the blood of mild to moderate patients in the treatment group compared to an increase in the placebo group; and
·The progression of Alzheimer’s disease was slowed down in the more severely affected patients in the treatment group compared to the placebo group. The initial findings of the study indicate the rate of cognitive deterioration was slowed in these patients.

Upon completion of the 36 week double blind portion of the PBT1-011AD trial, all of the patients who participated in such trial were offered the opportunity to continue into an extension trial, known as PBT1-011ADEX. Of the 36 patients who commenced the PBT1-011AD trial, 27 continued into the PBT1-011ADEX trial and 18 completed the additional 48 weeks of treatment with clioquinol. In April 2004, a summary of the top-line findings of the 48-week extension study were presented for the first time by Professor Colin Masters at the 8th International Springfield/Montreal Symposium on Advances in Alzheimer'sAlzheimer’s disease. The details of the trial findings haveare available on our website (www.pranabio.com), however the information in our website is not been published as yet.incorporated by reference into this annual report. In April, 2005, we ceased clinical trials of our PBT-1 compound in Alzheimer’s disease. See Item 4.A. "Information on the Company - History and Development of the Company."
In 2003, PBT-2 successfully completed in-house preclinical screening in 2003 and at presentthe initial formal preclinical toxicology screening is being completed. If successful, it is intended that PBT-2 will move intotesting required to support initial human trials. In March 2005, we commenced a series of Phase I clinical trials, at a facility associated with the Utrecht University Hospital in earlyUtrecht, the Netherlands. On November 7, 2005, we announced the successful completion of the first Phase I trial for PBT-2. See Item 4.A. "Information on the Company - History and Development of the Company." We have also completed three out of four stages of a second Phase I multi-dose escalation safety clinical trial of PBT-2 in elderly, healthy, male and female volunteers. We anticipate completing the final dosing stage in December 2005. In addition, the preclinical toxicology studies and GMP manufacturing development required for Phase II and Phase III clinical studies of PBT-2 are concurrently underway. No assurance can be given that PBT-2 will succeed in formal toxicology testing or that such future clinical studies will commence, or if initiated will be completed and prove to be successful, or that we will be able to commercialize drugs based on our (beta)AmyloidβAmyloid theory of Alzheimer's disease. It was reported that approximately 4.5 million persons in the United States suffered from Alzheimer's disease in 2000, more than double the number of persons in the United States who suffered from the disease in 1980. We and our scientific advisory board believe that our technology, if proven successful, will place our company among the leaders in the world in terms of developing a therapeutic means to treat Alzheimer's disease.
Rational Drug Design
Rational drug design employs experiment based, computer-generated models, which target the molecular composition of various substances (in the case of Alzheimer'sAlzheimer’s disease the (beta)AmyloidβAmyloid Protein) and design new chemical entities with the propensity to influence the targeted substances (proteins). and metal-mediated oxyradical formation which leads to neurodegenerative changes.
Our medicinal chemistry program is based at the University of Melbourne. To date, our scientists have developed a pipeline of compounds across multiple chemical classes that target the interaction of specific metals and the (beta)Amyloid Protein. These compoundstarget aggregating proteins such as βAmyloid. Compounds continue to be designed, synthesized and undergo the required early phase preclinical screening test before they are available for human testing.Based on the results of initial screening, our medicinal chemists continue to develop new chemical entities with novel design features. Althoughfeatures and we believe that we have demonstrated "proof of principle" in our phase II trials utilizing PBT-1, we also believe that rational drug design will provide new and specifically designed drugs which will display greater efficacy in disaggregating aggregation-prone proteins 18 such as (beta)Amyloid,βAmyloid, α-synuclein and huntingtin, paving the way for future therapeutics.
A series of in vitro assays have been established to screen compounds developed by our medicinal chemistry group. From early 2002, a program was initiated to undertake preliminary in vivo pharmacology and kinetic studies of the new compounds demonstrating activity in the in vitro screens was established by our medical chemistry group. The Alzheimer’s disease transgenic mouse model that demonstrated efficacy of PBT-1 and animal models for Parkinson’s disease and Huntington’s disease are currently being used by our medical chemical group to evaluate in vivo efficacy and confirm the selection of lead compounds to take to formal pre-clinical studies. Data generated by these in vitro and in vivo screens will also be incorporated into the medicinal chemistry program to further refine development strategies for new compounds.

PBT-2, our current lead MPAC product candidate, was selected from this “rationally designed” pipeline in 2003 and is the first such new and specifically designed compound to move into formal development. In early August 2003, we announced that PBT-2, a new lead MPAC molecule for Alzheimer's disease, had been selected for development. PBT-2 is the result of rational drug design. It has been built "from“from the ground up"up” to fulfill very specific criteria. It was designed so that it will have no patent ambiguities, be orally bioavailable and cross the blood brain barrier. PBT-2 has beenwas selected from over 400 Prana-developed300 compounds that had been developed by us at such time and has demonstrated significantly greatersignificant effectiveness in both pre-clinical in-vitroin vitro and in-vivoin vivo testing and has been designed to have an improved safety and efficacy profile compared to PBT-1. Creutzfeldt-Jakob Disease In 2001, British studies revealedprofile. PBT-2 has completed formal preclinical toxicology testing and in March 2005, we commenced a much greater potential for the spreadseries of fatal brain diseases such as Creutzfeldt-Jakob disease, or CJD, the human variant of Mad Cow disease. In August 2000, the London-based Medical Research Council warned that the disease could be more widespread than previously thought and that healthy appearing animals can be carriers of the disease. Mad Cow disease entered the human food chain in the 1980's leading toPhase I clinical trials at a collapse of the entire beef trade in the United Kingdom at the time. There is currently no cure for this fatal disease. In early 2001, the scientific journal Biochemistry published research results by Prana-sponsored scientist Dr. Roberto Cappai and colleagues confirming the role of metals in the aggregation and neurotoxicity of the abnormal form of the prion protein (PrP), believed to be responsible for the transmissible spongiform encephalopathics. Studies conducted by the University of Melbourne are ongoing to identify compounds that inhibit prion formation based on the PrP metal binding site. At present we are not undertaking specific research into the development of specific MPACs for prion diseases such as CJD, however through our close relationship with Professor Masters and his world-leading independent laboratory at the University of Melbourne, we believe that we have the capability to rapidly move into this field when and if it is deemed appropriate. Age-Related Cataracts Basic research in this area is being conducted by several independent groups of researchers around the world. Preliminary animal data suggests that the deposition of some proteins in age related cataracts may be related to the inappropriate interaction of metals and amyloid species. We are aware of the growing evidence in this area and when adequate information becomes available, will assess the data and determine if further company funds will be invested in this area. Motor Neuron Disease (or Amyotrophic Lateral Sclerosis) Amyotrophic Lateral Sclerosis, or ALS, is a fatal disease, manifested by progressive paralysis over five to ten years. There is currently no effective therapy for this tragic illness. The disease involves degeneration of the nerve cells in the spinal column, which has now been related to mutations of a protein that interacts with metal ions. Studies through other internationally recognized research groups are progressing, and preliminary animal experiments are in progress to identify the role of SOD1 (superoxide dismutase) aggregation in Motor Neuron disease. The mechanisms underlying this disease have 19 not been fully discovered, but the oxidative changesfacility associated with the aggregationUtrecht University Hospital in Utrecht, the Netherlands. On November 7, 2005, we announced the successful completion of critical proteins in the spinal cordfirst Phase I trial for PBT-2. See Item 4.A. "Information on the Company - History and brain stem continue to be atDevelopment of the centerCompany." We have also completed three out of four stages of a world-wide research effort. It is possible thatsecond Phase I multi-dose escalation safety clinical trial of PBT-2 in elderly, healthy, male and female volunteers. We anticipate completing the oxidative changes associated with ALS may be susceptible to treatment with Prana's drug technology. A more specific drug target is expected to emergefinal dosing stage in December 2005. In addition, the near future. Parkinson's Disease Parkinson's disease is another crippling diseasepreclinical toxicology studies and GMP manufacturing development required for Phase II and Phase III clinical studies of the aging population. It causes a progressive slowing of movement, tremor and the loss of fine motor control. Increasingly, dementia is being recognized as a significant component of Parkinson's disease. Existing therapies may provide some short term symptomatic relief but do not address the underlying cause of the disease. We believe that our platform technology may affect the aggregation of the proteins concerned and may provide a pathway for reversing the disease. Parkinson's disease is believed to affect 150 people per 100,000 or 2.5% of persons over the age of 85. It has been reported that approximately four million people suffer from Parkinson's disease worldwide. The Melbourne research team is working on the key protein which aggregates to form the diagnostic marker of this disease. The aggregated form of this protein is susceptible to the same therapeutic strategy that is being used for Alzheimer's disease, and scientists associated with Prana have published results in the peer reviewed journal Neuron in March 2003, indicating that PBT-1 can prevent the neurotoxicity seen in the MPTP mouse model of Parkinson's disease. Experiments to confirm that other Prana MPACs have a similar effect and that these findingsPBT-2 are applicable in human Parkinson's disease are planned but have not been conducted as yet. 20 concurrently underway.

Patent Matters
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. Statutory differences in patentable subject matter may limit the protection we can obtain on some or all of our inventions outside Australia or prevent us from obtaining patent protection outside Australia, either of which could have a material adverse effect on our business, financial condition and results of operations. For example, methods of treating humans are not patentable in many countries outside Australia and the United States. Moreover, since patent applications are not published until at least 18 months from their first filing date and the publication of discoveries in the scientific literature often lags behind actual discoveries, we cannot be certain that we or any of our licensors were the first creator of inventions covered by pending patent applications or that we or our licensors were the first to file patent applications for such inventions. Additionally, the enforceability of a patent is dependent on a number of factors that may vary between jurisdictions. These factors may include the novelty of the invention, the requirement that the invention not be obvious in the light of prior art (including prior use or publication of the invention), the utility of the invention, and the extent to which the patent clearly describes the best method of working the invention.
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. We also cannot be certain that others will not independently develop similar products or processes, duplicate any of the products or processes developed or being developed by us or licensed to us, or design around the patents owned or licensed by us, or that any patents owned or licensed by us will provide us with competitive advantages. Furthermore, we cannot be certain that patents held by third parties will not prevent the commercialization of products incorporating the technology 23 developed by us or licensed to us, or that third parties will not challenge or seek to narrow, invalidate or circumvent any of the issued, pending or future patents owned or licensed by us.
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 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. Such litigation could result in substantial costs and diversion of effort by us. We may have to participate in opposition proceedings before the Australian Patent and Trademark Office or another foreign patent office, or in interference proceedings declared by the United States Patent and Trademark Office, to determine the priority of invention for patent applications filed by competitors. Any such litigation, interference or opposition proceeding, 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.
27

In addition to patent protection, we rely on unpatented trade secrets and know-how and proprietary technological innovation and expertise that are protected in part by confidentiality and invention assignment agreements with our employees, advisors and consultants.

Competition
We believe that we will face competition in differing levels of intensity in all of the areas in which we are conducting research. Our competitors in Australia and elsewhere are numerous and include, among others, 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 obsoleteor non-competitive.Many of these competitors have greater financial, research and screening capabilities, 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.

Regulatory Considerations
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 Therapeutic Goods Administration, or TGA, and by the Federal Drug Authority, or FDA, in the United States, the Medicines Control Agency, or MHRA, in the United Kingdom and the European Medicines Evaluation Authority.Authority, or EMEA. Prior to marketing, any therapeutic product developed must 24 undergo rigorous pre-clinical testing and clinical trials, as well as an extensive regulatory approval process mandated 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 StatesEMEA and the Medicines Control Agency in the United Kingdom.MHRA. Clinical trials are conducted in three sequential phases but the phases may overlap.
Pre-clinical studies involve laboratory evaluation of product characteristics and animal studies to assess the initial efficacy and safety of the product. Clinical trials involve the administration of the investigational product to humans under the supervision of a qualified principal investigator. Phase I clinical trials may be performed in healthy human subjects or, depending on the disease, in patients. The goal of phase I clinical trials is to establish initial data about the safety, tolerance and tolerancepharmacokinetics of the product in humans. In phase II clinical trials, in addition to safety, the efficacy of the product is evaluated in limited patients with the target disease. Phase III trials typically involve additional testing for safety and clinical efficacy in expanded, large-scale, multi-center studies of patients with the target disease.
28

Clinical trials can take many years to complete and require the expenditure of substantial resources. The length of time varies substantially according to the type, complexity, novelty and intended use of the product candidate. Delays in obtaining regulatory approvals could adversely affect the development and commercialization of our pharmaceutical product candidates and could have a material adverse impact on our business, financial condition and results of operations.
We have completed formal preclinical toxicology testing of PBT-2 and in March 2005, we commenced a phase II humanseries of Phase I clinical trials at a facility associated with the Utrecht University Hospital in Utrecht, the Netherlands. On November 7, 2005, we announced the successful completion of the first Phase I trial for PBT-2. See Item 4.A. "Information on the Company - History and Development of the Company." We have also completed three out of four stages of a second Phase I multi-dose escalation safety clinical trial of PBT-1PBT-2 in late 2002elderly, healthy, male and its associated extension studyfemale volunteers. We anticipate completing the final dosing stage in 2003December 2005. In addition, the preclinical toxicology studies and will need to complete furtherGMP manufacturing development required for Phase II and more detailed trials before we will be able to make any application to anyPhase III clinical studies of the governmental authorities. We have completed a detailed in-house review of requirements to progress the development of PBT-1 to enable application to regulatory agencies. Initially the focus is on FDA requirements for registration in the United States. Harmonization of regulatory requirements through the International Conference on Harmonization (ICH) and the Common Technical Document (CTD), will enable the regulatory application for the United States to be utilized for applications in Europe and other countries including Australia, providing some limited country specific requirementsPBT-2 are addressed. A decision on the path forward with PBT-1 will be made based on this assessment, taking account of the potential requirements of future partners and the progress with PBT-2 and other future compounds.concurrently underway. We cannot make any assurances that we will complete the Phase I program for PBT-2 or enter further clinical trials with PBT-1. PBT-2.
We cannot make any assurances that we will be able to enter into a collaborative arrangement with a large pharmaceutical or biotechnology company to commercialize PBT-1.PBT-2. Nor can we make any assurances that once clinical trials are completed by us or a collaborative partner, we will be able to submit as scheduled a marketing approval request to the applicable governmental regulatory authority, or that such request and application will be reviewed and cleared by such governmental authority in a timely manner, or at all. Although we intend to make use of fast-track and abbreviated regulatory approval programs when possible, 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. 25
During the course of clinical trials and toxicology studies, product candidates may exhibit unforeseen and unacceptable drug-related toxicities or side effects. If any unacceptable toxicities or side effects were to occur, we may, or regulatory authorities may require us to, interrupt, limit, delay or abort the development of our potential products. In addition, unacceptable toxicities could ultimately prevent the clearance of our product candidates by the TGA or the FDA for any or all targeted indications. Even after being cleared by the TGA or the FDA, any of our products may later be shown to be unsafe or not to have its purported effect, thereby preventing widespread use or requiring withdrawal from the market. We cannot make any assurances that PBT-1PBT2 or any of our otherfuture product candidatescandidate (including PBT-1) will be safe or effective when administered to patients.
Manufacturing and Raw Materials
We usehave used a third party manufacturer to produce the primary drug product (API) and secondary drug forms for our large-scale, preclinical and clinical supplies of PBT-1 and PBT-2.PBT-2 trials, and we expect that we will use a third party manufacturer for any future product candidates. We have not faced any difficulty in obtaining raw materials for our research and development activities or our clinical studies to date, although recognize that this is a costly, complex and time consuming process. Future supplies of PBT-2 for clinical trials have been commissioned within Australia, while supplies of PBT-1 will most likely be manufactured outside Australia. No assurance can be givenWe cannot make any assurances that we wouldwill be able to replace this suppliermanufacture sufficient quantities of PBT-2 or any future product candidates (including PBT-1) 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 a timely basis, ifour business, financial condition and results of operations. We also cannot make any assurances that we werewill be able to enter into collaborative or contracting arrangements on acceptable terms with third party manufacturers that will meet our requirements for quality, quantity and timeliness.
29

We expect that we will be required to find another sourcedesign and develop new synthetic pathways for most, if not all, of PBT-1 or PBT-2. Government Grants We announced on July 26, 2001the products that we were grantedcurrently intend to develop. We can not predict the success of such efforts, the purity of the products that may be obtained or the nature of the impurities that may result from such efforts. If we are not able to obtain an acceptable purity for any product candidate or an acceptable impurity profile, pre-clinical and clinical trials would be delayed, which could have a START grant frommaterial adverse effect on the priority of the development of our product candidates, our business, financial condition and results of operations.
Government Grants
In May 2003, we announced that the Australian Industry Research and Development Board, or IR&D Board, to expand our core intellectual property for drug treatment of neuro-degenerative diseases. Under the terms of the grant, we received A$1.7 million during the three year period commencing January 1, 2001 for up to 50% of the project costs related to our development of a treatment for Alzheimer's disease. The grant was payable on the achievement of each of six milestones and we received the final payment under the START grant in October 2003. In May 2003, we announced that the IR&D Board approved our application for funding under the BIFBiotechnology Innovation Fund grant forin the amount of A$227,252 for research into the development of an immunotherapy for Alzheimer'sAlzheimer’s disease. The research under this grant was completed in January 2005 following the completion of certain project milestones stipulated in the grant, demonstrating that a mouse could generate antibodies that preferentially recognize dimerized βAmyloid.
In the first quarter of 2004, we were granted a new START grant from the Australian IR&D Board to support further development of PBT-2 and other Alzheimer'sAlzheimer’s disease research. Like the first START grant, theresearch up to an amount of A$1.35 million. The grant is payable, in arrears, on the achievement of pre-specified milestones. We can make no assurances that we can achieve these milestones or receive all of the A$1.35 million made availablesuch amount. The research under this grant was initially to be completed over a two year period and such period was subsequently extended until the end of 2005. As of September 30, 2005, we were entitled to approximately A$1.15 million under thethis grant. Business Plan To date, the majority of our research efforts have been directed at research into the Alzheimer's disease. Our initial findings have provided strong indications that the pathology for other certain age-related and degenerative disorders may also be based on the inter-relationship between certain metals and proteins. These diseases include: 26 o Age-related cataracts o Creutzfeldt-Jakob disease o Motor Neuron disease/Amyotrophic Sclerosis (ALS) o Parkinson's disease We believe that our phase II human clinical trial of PBT-1 has demonstrated proof of principle of our theory of Alzheimer's disease and that rational drug design will provide new and specifically designed drugs which will display greater efficacy in disaggregating aggregation prone proteins such as (beta)-amyloid, paving the way for the development of new therapeutic agents. To that end, we have established a drug discovery and development program at the School of Chemistry, and Department of Pathology at the University of Melbourne and the Mental Health Research Institute of Victoria. Rational Drug Design Our medicinal chemistry program is based at the University of Melbourne. Rational drug design employs computer-generated models, which target the molecular composition of various substances, in the case of Alzheimer's disease the a-amyloid protein, and designs new chemical entities with the propensity to influence the targeted proteins and metal-mediated oxyradical formation which leads to neurodegenerative changes. A series of in vitro assays have been established to screen compounds developed by the medicinal chemistry group. During 2002/03 a program to undertake preliminary in vivo pharmacology and kinetic studies of the new compounds demonstrating activity in the in vitro screens has been established. The transgenic mouse model that demonstrated efficacy of PBT-1 is continuing to be used to evaluate in vivo efficacy and confirm lead compounds to take to formal pre clinical studies. In early August 2003, we announced that PBT-2, a new lead MPAC molecule for Alzheimer's disease, had been selected for development. PBT-2 is the result of rational drug design. It has been built "from the ground up" to fulfill very specific criteria. It was designed so that it will have no patent ambiguities, be orally bioavailable and cross the blood brain barrier. PBT-2 has been selected from over 400 Prana-developed compounds and has demonstrated significantly greater effectiveness in both pre-clinical in-vitro and in-vivo testing and has been designed to have an improved safety and efficacy profile compared to PBT-1. The new drug is expected to enter into Phase I human clinical trials in 2005, following a formal toxicology program. Data generated by in vitro and in vivo screens will also be incorporated into the medicinal chemistry program to further refine development strategies for new compounds.
Commercial Collaboration
In March 2003, we announced thata collaboration with Schering A.G. (FSE:SCH, NYSE:SHR) of Germany willto fund and license research discoveries, on new drug targets, especiallyparticularly in the area of imaging and diagnostics, under project agreements between us and Neurosciences Victoria Ltd. and a separate research and 27 collaboration agreement between Schering A.G. and Neurosciences Victoria Ltd. The parties concluded this collaboration as of June 30, 2005. The commercial arrangements that we entered into in connection with such collaboration are subject to ongoing confidentiality. Under the collaboration, Schering A.G. is providing to us up to A$2.7 million of funding for new discovery research over the life of specified research and development projects that we will conduct, with additional milestone payments and royalties from discoveries. See Item 4A. "Information“Information on the Company - History and Development of the Company."
In August 2003, utilizing the grant we andreceived from the Commonwealth Government of Australia under the BIF, we entered into an agreement with Prima, Biomed, or Prima (ASX code: PRR) formed a collaboration withthrough its collaborative research partner, the Austin Research Institute, and the University of Melbourne to develop the world's first vaccine for Alzheimer's disease. The collaboration will enable Prima Biomed's highly encouraging new Panvax vaccine technology, called DCtag, to be used in conjunctiontogether with our metal protein attenuating compounds (MPAC) to assist the body's immune system to recognize the protein or peptide extracts associated with Alzheimer's disease. DCtag has already been shown to be effective in targeting diseases such as malaria and cancer. In February 2003, Panvax announced the results of animal studies confirming the potential of DCtag technology for the development of vaccines and immunotherapies. The research and development will be conducted by the Austin Research Institute and the University of Melbourne and is supported bythe Mental Health Research Institute, to undertake proof of concept research for our prospective Alzheimer’s disease vaccine target. This collaboration enabled us to access Prima's adjuvant vaccine technology, known as DCtag, in the design of candidate vaccine fragments. Under the terms of our contractual relationship with Prima, we retained all commercial rights to the monoclonal antibodies and Prima and us will be the joint owners of any new intellectual property arising from the collaboration. This proof of concept research was completed in January 2005. We are currently negotiating a Commonwealth government grantcontract with Prima to undertake the characterization and scale-up of A$227,252.prospective antibody candidates that were identified during the initial proof of concept stage for testing in future passive vaccine trials in Alzheimer's disease model mice. We will be utilizing the resources of Prima, the Austin Research Institute, the University of Melbourne and the Mental Health Research Institute to pursue this therapeutic approach. The research will assess the feasibility of developing a vaccine to prevent the onset or progression of Alzheimer's disease. It will also assess the effectivenessability of the technologyprospective antibody candidates to enhancetarget the production“toxic linked” forms of antibodies as an effective Alzheimer's disease treatment. We and Prima will jointly share in the benefit of any intellectual property produced from the collaboration including milestone payments and royalties that may accrue as a consequence of producing a successful vaccine therapy. Research programs Alzheimer's disease. Research is ongoing to increase our understanding of the neuropathology of Alzheimer's disease. In the next 12 months, our research will focus on the structure and function of (beta)-amyloid and its precursor, and protein structural studies specifically around the sites of interaction between metals, metal complexes and our MPACs and the significant proteins in Alzheimer's disease such as APP and (beta)-amyloid. Phase I clinical trials are planned for 2005 in order to advance PBT-2 toward commercialization. Leading clinical institutes in both the United States and Europe are investigating the possibility of clinical trials with PBT-1. Prana is investigating the possibility of partnering with these institutes to optimize the clinical trials they are planning. The possibility of partnering with these institutions or leading the development of PBT-1 through these institutes is under investigation. We can give no assurance that trials will be initiated with either PBT-1 or PBT-2, or if initiated that they will be completed or prove to be successful. The research and development projects under our licensing and research collaboration with Schering A.G. and Neurosciences Victoria Ltd. will concentrate on the development of a new Alzheimer's diagnostic. We are seeking to develop the first highly reliable diagnostic for Alzheimer's disease using brain imaging of specific compounds as markers to measure the debilitatingbeta amyloid deposits. See Item 4A. "Information on the Company - History and Development of the Company." 28 Creutzfeldt-Jakob disease. In early 2001, the scientific journal Biochemistry published research results by our sponsored scientist, Dr. Roberto Cappai, and his colleagues confirming the role of metals in the aggregation and neurotoxicity of the abnormal form of the prion protein (PrP), believed to be responsible for the transmissible spongiform encephalopathies. Age-Related Cataracts. Basic research in this area is continuing with ongoing studies. Data to date indicate that some age-related cataracts contain the same protein aggregation as that seen in Alzheimer's disease. At present Prana is not undertaking active research in this area, although through the close ties with Professor Masters and the University of Melbourne Prana retains the ability and opportunity to investigate the usefulness of its MPAC portfolio in treating and/or preventing Age Related Cataracts, if and when additional evidence arises to prioritise this opportunity. We can give no assurance that such research will continue or if continuing will be successful. Motor Neuron disease/Amyotrophic Lateral Sclerosis. Collaborative studies with other internationally recognized research groups are progressing, and preliminary animal experiments are in progress to identify the role of SOD1 (superoxide dismutase) aggregation in Motor Neuron disease. The mechanisms underlying this disease have not been fully elucidated, but the oxidative changes associated with the aggregationpathology of critical proteins in the spinal cord and brain stem continue to be at the center ofAlzheimer’s disease, as a world-wide research effort. A drug target is expected to emerge in the near future. Parkinson's disease. Our Melbourne research team is working on the key protein (alfa-synuclein) that aggregates to form the diagnostic marker of this disease. We believe that the aggregated form of this protein is susceptible to the samepossible vaccine therapeutic strategy that is being usedapproach for Alzheimer's disease, and laboratory tests are in progress to confirm this approach. Experimental animal models are developed and are being integrated into the rationale drug design screening regime. Further targets for drug development are expected to be available within the next 12 months. The molecules already developed as parttreatment of the Alzheimer's disease program are being used to clarify the rationale drug development strategy required to optimize molecules for Parkinson's disease. This testing is expected to continue through 2005.

C. ORGANIZATIONAL STRUCTURE Organizational Structure
In August 2004, we established two wholly owned subsidiaries, Prana Biotechnology Inc., incorporated in the United States, and Prana Biotechnology UK plc, incorporated in the United Kingdom. Prana Biotechnology Inc. was established in the United States due to the increase in our U.S. operations including the appointment of Mr. Jonas Alsenas, a U.S.-based director, as our Chief Executive Officer, and the increase in U.S. investors in our company. Prana Biotechnology UK plc was established in the United Kingdom to allow us to conduct commercial and clinical operations in the United Kingdom. 29
D. PROPERTY, PLANTS AND EQUIPMENT Property, Plants and Equipment
We own computer equipment, office furniture and lab equipment, the major item being a mass spectrometer that is being used at the University of Melbourne. We are party to a three year property lease signed in May 2004 that provides executive office space at 369 Royal Parade, Parkville, Victoria 3052, Australia, at an initial annual rental of A$105,551, which is increased by 3.5% on a cumulative basis on the May anniversary of the lease.

A.Operating Results
Background

We were incorporated under the laws of the Commonwealth of Australia on November 11, 1997. Our mission is to develop therapeutic drugs designed to treat the underlying cause of degeneration of the brain and the eye as the aging process progresses. The principal listing of our ordinary shares and listed options to purchase our ordinary shares is on the Australian Stock Exchange, or ASX. Since September 5, 2002, our American Depository Receipts, or ADRs, have traded on the NASDAQ Capital Market under the symbol “PRAN.” We have two wholly-owned subsidiaries, Prana Biotechnology Inc. and Prana Biotechnology UK Limited, incorporated in the United States and the United Kingdom, respectively, in August 2004.

Our financial statements appearing in this annual report. report are prepared in Australian dollars and in accordance with generally accepted accounting principles in Australia. In this annual report, all references to “U.S. dollars” or “US$” are to the currency of the United States of America, and all references to “Australian dollars” or “A$” are to the currency of Australia.

All of our revenues are generated in Australian dollars, except for interest earned on foreign currency bank accounts, and the majority of our expenses are incurred in Australian dollars.

Overview

We are a development stage enterprise 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 aging progresses. We have incurred net losses since inception and expect to incur substantial and increasing losses for the next several years as we expand our research and development activities and move our product candidates into later stages of development. All of our product candidates are in early stages of development and we face the risks of failure inherent in developing drugs based on new technologies. The process of carrying out the development of our products to later stages of development may require significant additional research and development expenditures, including pre-clinical testing and clinical trials, as well as for obtaining regulatory approval. To date, we have funded our operations primarily through the sale of equity securities, proceeds from the exercise of options, government grants, licensing and research collaborations and interest income.

Since completing our initial public offering and listing process on the ASX on March 28, 2000, we have concentrated our resources toward the pursuit of our disease targets. Initially we focused on clinical trials of our PBT-1 compound as a therapeutic for the treatment of Alzheimer’s disease. We commenced our planned phase II human clinical trial for PBT-1 in August 2000 at the Mental Health Research Institute and the Royal Melbourne Hospital. The 36 week trial was completed in January 2002. All patients from this study were then provided the opportunity to roll into a further 48 week extension study. 32 out of 36 patients completed the initial trial, out of which 27 patients elected to start the extension study and 18 patients completed the full 84-week study. On October 12, 2004, we announced the results of the open label 84-week “Extension Study” of our Phase II clinical trial of PBT-1. On October 18, 2004, we announced plans to pursue a Phase II/III study to examine the effect of PBT-1 in moderate to severe Alzheimer’s disease patients in the second quarter of 2005, to be known as the PLACQUE (Progression Limiting in Alzheimer’s: Clioquinol’s Efficacy) study. On April 11, 2005, we announced that we would not proceed with the PLACQUE study and that we had re-evaluated our further work on the PBT-1 program. As part of our effort to manufacture Good Manufacturing Practice (GMP) grade PBT-1 clinical trial material, we characterized the various impurities that occur in the synthetic process and found unacceptably high levels of a di-iodo-8-hydroxyquinoline impurity that could potentially increase the risk of side-effects and mutagenicity. We considered methods to reduce the levels of the di-iodo impurity, however, we reached the conclusion that attempts to reduce the impurity to safe levels were not likely to be successful in a timely, commercially viable manner and that further development of PBT-1 for the treatment of Alzheimer’s disease was not appropriate. As a result of these events, we proceeded to conduct a strategic review of our pending strategic development programs. 
32

On June 16, 2005, we announced that we had completed a review of our strategic development programs and we reaffirmed our commitment to our other lead candidate for the potential treatment of Alzheimer's disease, PBT-2. Unlike PBT-1, PBT-2 has a structure that does not contain iodine and is therefore not capable of forming the di-iodo impurity that has been associated with mutagenicity. PBT-2 was announced as a new lead metal protein attenuating compound, or MPAC, molecule for Alzheimer’s disease in early August 2003. PBT-2 is the result of rational drug design. It has been built “from the ground up” to fulfill very specific criteria. It was designed so that it will be orally bioavailable and cross the blood brain barrier. PBT-2 was selected from over 300 compounds that had been developed by us at such time and has demonstrated significant effectiveness in both pre-clinical in vitro and in vivo testing and has been designed to have an improved safety and efficacy profile compared to PBT-1. In February 2004, we were awarded a second research and development START grant of A$1.35 million to take PBT-2 through safety testing and Phase I clinical trials for Alzheimer's disease. Formal preclinical toxicology testing for PBT-2 has been completed and in March 2005, we commenced a series of Phase I clinical trials at a facility associated with the Utrecht University Hospital in Utrecht, the Netherlands. On November 7, 2005, we announced the successful completion of the first Phase I trial for PBT-2, a double blind, placebo-controlled single dose escalation study, conducted on 55 healthy, male volunteers between the ages of 18 and 50, which was designed to evaluate the safety, tolerability and pharmacokinetics of PBT-2. Data from the study shows that PBT-2 was well tolerated with little difference in the incidence of adverse events between those receiving PBT-2 and those receiving the placebo. Additionally, the pharmacokinetic analysis demonstrated that the drug exposure increased predictably and in a linear manner, both of which are strong characteristics for a central nervous system drug. Concurrent findings in a pre-clinical mouse model indicate that PBT-2 passes into the brain more extensively than its predecessor, PBT-1. We have also completed three out of four stages of a second Phase I multi-dose escalation safety clinical trial of PBT-2 in elderly, healthy, male and female volunteers. We anticipate completing the final dosing stage in December 2005. In addition, the preclinical toxicology studies and GMP manufacturing development required for Phase II and Phase III clinical studies of PBT-2 are concurrently underway.

Recently Issued But Not Yet Adopted Accounting Pronouncements Applicable toTo Us

Australian Pronouncements The revised Australian Accounting Standard AASB 1020, "Income Taxes," is applicable to financial years ended on or after December 31, 2005 (fiscal year 2006 for our company). The key implication of this revised standard is that for our intangible assets that have previously been revalued upwards, we will recognize the equivalent deferred tax liability. When these assets are subsequently depreciated, the additional depreciation will be tax effected and will result in an increased profit after tax compared to the existing standard. We have not yet completed an assessment of the impact of this revised standard on our results of operations or financial position.

On July 3, 2002, the Australian Financial Reporting Council announced that Australia would adopt International Financial Reporting Standards, or IFRS, for financial years beginning on or after January 1, 2005 (fiscal year 2006 for our company).Standards. Our management ishas been assessing 30 the significance of these changes and preparing for their implementation. We are of the opinion that the key differences in our accounting policies which will arise from the adoption of IFRS are: o Our policy is to expense the value of shares issued in lieu of payment for goods or services by valuing them at their cost under the respective contract; however, under IFRS we will be required to expenseprepare consolidated financial statements that comply with Australian equivalents to International Financial Reporting Standards, or IFRS, for reporting periods beginning on or after January 1, 2005. Accordingly, our first half-year report prepared under Australian IFRS will be for the costhalf-year reporting period ending December 31, 2005, and our first annual financial report prepared under Australian IFRS will be for the year ending June 30, 2006.

We have completed a study of such shares basedthe impact of the Australian IFRS as a consolidated entity, including the formulation of the Australian IFRS accounting policies that are intended to be adopted from July 1, 2005. The likely impact of the accounting policy changes on the fair value (i.e., market price)results and financial position of the shares. Additionally, under IFRS we will be requiredconsolidated entity has been determined and disclosed in Note 1(t) (unaudited) to expense the cost of share options issued based on the fair value of the options at the grant date. Currently, we do not recognize compensation cost for option grants. o We currently have intangible assets which were revalued upward by A$14.7 million in 1999, which are being amortized over their useful life of up to 15 years. For the revaluation increment to continue to be recognized under IFRS there must be an active market in which the intangible can be traded. The intangible assets must also be the result of contractual or legal rights or separable from the business. It is anticipated that the intangible assets will not be able to be separately identified and that there will be no active market in which to value the intangible assets. As a result, the revaluation increment may be derecognized from the statement ofconsolidated financial position and the amortization previously taken up may be reversed. statements.

United States Pronouncements In January 2003,

On December 16, 2004, the Financial Accounting Standards Board, or FASB, issued Statement of Financial Accounting Standards (“SFAS”) No. 123 (revised 2004), "Share-Based Payment", or SFAS 123(R), which is a revision of SFAS No. 123, “Accounting for Stock Based Compensation”, or SFAS 123. Generally, the approach in SFAS 123(R) is similar to the approach described in SFAS 123. However, SFAS 123 permitted, but did not require, share-based payments to employees to be recognized based on their fair values while SFAS 123(R) requires all share-based payments to employees to be recognized based on their fair values. SFAS 123(R) also revises, clarifies and expands guidance in several areas, including measuring fair value, classifying an award as equity or as a liability and attributing compensation cost to reporting periods. The new standard will be effective for us commencing July 1, 2005.

As permitted by SFAS 123, we currently account for share-based payments to employees using Accounting Principles Board, or APB, Opinion No. 25, “Accounting for Stock Issued to Employees,” the intrinsic value method. Accordingly, the adoption of the SFAS 123(R) fair value method may have significant impact on our results of operations, although it will have no impact on our overall financial position. The impact of the adoption of SFAS 123(R) cannot be predicted at this time, as it depends on levels of share-based payments for future grant. However, had we adopted SFAS 123(R) in prior periods, the impact of that Standard would have approximated the impact of SFAS 123, as disclosed in Note 25(a) of our financial statements included in this Report.

In December 2004, the FASB Interpretationissued SFAS No. 46, "Consolidation153, "Exchanges of Variable Interest Entities--an InterpretationNonmonetary Assets - an amendment of ARBAPB Opinion No. 51,29," or FIN 46. FIN 46 is applicable immediatelySFAS 153, which amends APB Opinion No. 29, "Accounting for Variable Interest Entities, or VIEs, created after January 31, 2003Nonmonetary Transactions" to eliminate the exception for nonmonetary exchanges of similar productive assets and replaces it with a general exception for exchanges of nonmonetary assets that do not have commercial substance. SFAS 153 is effective for nonmonetary asset exchanges occurring in fiscal periods beginning after June 15, 2005. The new standard will be effective for us oncommencing July 1, 2003 for VIEs created prior to February 1, 2003. FIN 46 addresses consolidation by business enterprises of VIEs that either: (1)2005. At this time, we do not have sufficient equity investment at risk to permitanticipate that the entity to finance its activities without additional subordinated financial support or (2) the equity investors lack an essential characteristic of a controlling financial interest. In December 2003, the FASB published a revision to FIN 46, or FIN 46R, to clarify some of the provisions of FIN 46 and to defer the effective date of implementation for certain entities. Under the guidance of FIN 46R, public companies that have interests in VIEs that are commonly referred to as special purpose entities are required to apply the provisions of FIN 46R for periods ending after December 15, 2003. A public company that does not have any interests in special purpose entities but does have a variable interest in a VIE created before February 1, 2003 must apply the provisions of FIN 46R by the end of the first reporting period ending after March 14, 2004. The adoption of FIN 46 and FIN 46R during the year ended June 30, 2004 did notthis statement will have a material impacteffect on our consolidated financial conditionposition or results of operations.

34

In May 2005, the FASB issued FASB Statement No. 154, “Accounting Changes and Error Corrections: a replacement of APB Opinion No. 20 and FASB Statement No. 3”, or SFAS 154, which requires companies to apply voluntary changes in accounting principles retrospectively whenever it is practicable. SFAS 154 changes the requirements for the accounting for and reporting of a voluntary change in accounting principle as well as the changes required by an accounting pronouncement which does not include specific transition provisions. SFAS 154 will be effective for accounting changes made by us in fiscal years beginning after July 1, 2006. At this time, we do not anticipate that the adoption of SFAS 154 will have a material effect our consolidated financial position or results of operations.

Differences Between Australian Accounting Standards and U.S. Accounting Standards

We prepare our financial statements in accordance with generally accepted accounting principles in Australia, or A-GAAP, which differ in certain significant respects from generally accepted accounting principles in the United States, or U.S. GAAP.

Critical Accounting Policies

We prepare our financial statements in accordance with A-GAAP. As such, we are required to make certain estimates, judgments, and assumptions that management believes are reasonable based upon the information available. These estimates, judgments and assumptions affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the periods presented. The significant accounting policies listed in Note 1 of the financial statements that management believes are the most critical to aid in fully understanding and evaluating our financial condition and results of operations under A-GAAP are discussed below.

Recoverable amount of non-current assets.assets. Each reporting period, our Board of Directors assesses the recoverable amount of all non-current assets.assets to ensure its carrying value does not exceed its recoverable amount. Where the carrying amount of a non-current asset is greater than its recoverable amount, the asset is revalued down to its recoverable amount. The recoverable amount is estimated based on expected net cash flows discounted to their present values using a market-determined, risk-adjusted discounted rate.

On June 30, 2005, following the announcement in April 2005 regarding the cessation of our PBT-1 program, our Board of Directors determined that the core intellectual property relating to PBT-1 had been impaired and the carrying value was written-off.

Intangible assets and patents, research and development expense.expense. Until December 1999, costs associated with the acquisition and development of our core intellectual property were capitalized as intangible assets. After considering an independent valuation of our core intellectual property at December 1999, our Board of Directors revalued the assets upwards by A$14,661,942 to A$16,500,000. The revaluation was recorded in the asset revaluation reserve in equity. Subsequent to the revaluation, all costs associated with the acquisition and development of core intellectual property are charged to patents, research and development expense. On July 1, 2000, our Board of Directors deemed the revalued carrying amount of core intellectual property to be cost for financial reporting purposes. Our

Prior to the announcement in April 2005 regarding the cessation of our PBT-1 program, our core intellectual property is beingwas amortized on a straight-line basis over a period of 15 years, the period in which the future benefits arewere expected to arise. 32 On June 30, 2005, following such announcement, our Board of Directors determined that the core intellectual property relating to PBT-1 had been impaired and the carrying value was written-off.

Revenue recognition.recognition. We recognize revenue to the extent that it is probable that the economic benefits will flow to us and the revenue can be reliably measured. o Interest income is recognized as earned and collectibility is reasonably assured. o Government grants are recorded as income when key milestones set within each agreement are achieved and accepted by all parties to the grant. The agreements provide for payments at different phases based on product development. Milestones are based on the phases of each product development, for example phase 1, phase 2 and phase 3. Revenue is not recognized prior to acceptance that the milestones have been achieved, as collectibility is not assured until this point is reached. Once each milestone is reached and approved, the grantor is obligated to pay and there are no further significant obligations as to that part of the milestone. Grant income for achievement of such milestones is agreed between the parties in legally binding contracts. Revenue for each milestone achieved is fixed up front. The START grant is expected to complete advance toxicology in December 2004, commence Phase 1 clinical trials in March 2005 and conclude Phase 1 trials in August 2005. The BIF grant is expected to confirm proof of principle in January 2005. o Reimbursements of expenses are recognized as revenue when the reimbursement is received and the related expenses have been incurred. o Corporate partner revenues are comprised of amounts received for certain research and development activities under our collaboration with Schering A.G. and Neurosciences Victoria Ltd. Revenues are recognized as earned on a straight line basis over the lives of the respective agreements that we entered into with Neurosciences Victoria Ltd. in connection with the collaboration. The straight line basis is considered appropriate as such agreements do not contain clearly defined milestones. Such agreements are performed on a "best efforts" basis with no guarantee of either technological or commercial success.

Significant Costs and Expenses

Depreciation and amortization expense.expense. Depreciation of property and equipment is provided on a straight-line basis over the estimated useful lives of three to 14 years. AmortizationPrior to the impairment of our core intellectual property isas of June 30, 2005, amortization of our core intellectual property was provided on a straight-line basis over the estimated useful lives of 15 years. See Notes 1(c)1(d) and 1(d)1(e) to the financial statements.

Patents, research and development expenses.expenses. Our patents, research and development expenses consist primarily of compensation and related costs for research and development personnel, expenses for testing facilities and payments under our research agreements. Such costs are charged to operations as incurred. Patents, research and development expenses also include costs associated with the acquisition and development of patents, which have been expensed subsequent to December 1999. See Note 1(d)1(e) to the financial statements.

Legal expenses.expenses. Our legal expenses consist of fees paid to our outside counsel for various legal matters dealt with in the ordinary course of business as well as legal fees associated with patent applications and for the defense of patents. 33

Consulting fee expenses.expenses. Our consulting fee expenses consist primarily of directorsdirectors’ fees and other consultancy fees paid to members of our Scientific Advisory Board. scientists.

Employee benefits expenses.expenses. Employee benefit expenses consist primarily of payments to employees for their services as employees. employees, including our Chief Executive Officer.
37

Foreign exchange loss. Foreign exchange loss includes the net unrealized gain or loss on cash balances held in foreign currencies as well as net realized gains and losses on foreign currency transactions.

Impairment of intangible assets. Each reporting period, our Board of Directors reviews the carrying value of each non-current asset to ensure its carrying value does not exceed its recoverable amount. Where the carrying amount of the asset is greater than its recoverable amount, the asset is revalued down to its recoverable amount and an impairment charge is recorded.

Corporate compliance expenses.expenses. Corporate compliance expenses consist primarily of costs incurred by us to satisfy the requirements under Australian and U.S. listing and accounting standards. Costs include items such as share register fees, listing fees, audit fees and accounting and administration costs attributed to corporate compliance.

Other expenses from ordinary activities.activities. Other expenses from ordinary activities consist primarily of foreign exchange gains / losses, accounting and administrative services, travel, insurance, marketing and overhead expenses.

Results of Operations
Year ended June 30, 2005 compared to year ended June 30, 2004
Revenues from ordinary activities
Revenues from ordinary activities increased to A$2,653,113 for the year ended June 30, 2005 from A$2,321,227 for the year ended June 30, 2004, an increase of A$331,886, or 14.3%. Revenues in the year ended June 30, 2005 consisted of A$892,135 interest income, A$629,692 government grant income, and A$1,125,000 received under the licensing and research collaboration we entered into with Schering A.G. and Neurosciences Victoria Ltd. in March 2003. Revenues in the year ended June 30, 2004 consisted of A$211,327 interest income, A$647,400 government grant income, and A$1,462,500 received under the licensing and research collaboration we entered into with Schering A.G. and Neurosciences Victoria Ltd. in March 2003. The increase in revenues is attributable to a A$680,808 increase in interest income arising from the funds we received in June 2004 in connection with our US$20 million private placement of securities in the United States. This increase was partially offset by a A$337,500 reduction in funding from Schering A.G. and Neurosciences Victoria Ltd, due to the completion of one of the contracts in connection with our collaboration with Schering A.G and Neurosciences Ltd in June 2004. We estimate that our revenues in the 2006 fiscal year will consist of approximately A$700,000 of interest income and A$115,855 of government grant income.

Depreciation and amortization expenses
Depreciation and amortization expenses remained substantially consistent at A$1,165,227 for the year ended June 30, 2005 compared to A$1,195,006 for the year ended June 30, 2004.
38

Each reporting period, our Board of Directors reviews the carrying value of each non-current asset to ensure its carrying value does not exceed its recoverable amount. Where the carrying amount of the asset is greater than its recoverable amount, the asset is revalued down to its recoverable amount. On June 30, 2005, our Board of Directors reviewed the assets and determined to write-off all of the core intellectual property relating to PBT-1 which resulted in a charge of A$10,388,339.
Patents, research and development expenses
Patents, research and development expenses increased to A$7,687,596 for the year ended June 30, 2005 from A$5,232,581 for the year ended June 30, 2004, an increase of A$2,455,015, or 46.9%. The increase in expenses is attributable to an increase in pre-clinical and clinical trial costs, as we accelerated the research of PBT-1 and PBT-2. We expect that our patents, research and development expenses will increase in the 2006 fiscal year to approximately A$8.5 million, primarily due to further clinical trials and introducing new candidates for development.

Legal expenses
Legal expenses decreased to A$1,047,448 for the year ended June 30, 2005 from A$1,650,467 for the year ended June 30, 2004, a decrease of A$603,019, or 36.6%. The decrease in legal expenses was primarily due to the settlement of the dispute with P.N. Gerolymatos S.A. for which a provision of A$971,764 was made in the 2004 fiscal year. As a result of the settlement, our legal fees in respect of the action declined by A$94,938. This reduction was partially offset by the increase in legal fees of A$189,966 associated with Securities and Exchange Commission compliance following the filing of a registration statement in connection with the June 2004 private placement in the United States. In fiscal year 2005, legal fees in respect of employment matters also increased by A$58,027 and our intellectual property expenses increased by A$210,215. We expect that our legal expenses in the 2006 fiscal year will be substantially similar to those for the 2005 fiscal year.

Employee benefits expense
Employee benefits expenses increased to A$2,438,303 for the year ended June 30, 2005 from A$1,060,730 for the year ended June 30, 2004, an increase of A$1,377,573, or 129.9%. The increase in employee benefits expenses was primarily due to the increase in staff from 12 employees at June 30, 2004 to 17 employees at June 30, 2005. The increase in staff in the 2005 fiscal year was due to the acceleration of our research and development for our principal product candidate PBT-2 during such period, and the establishment of our office in the United States. The increase in the number of employees also affected our costs associated with their employment (such as taxes on salaries). Employee benefits expenses also increased in the 2005 fiscal year because Dr. Jonas Alsenas, who served as our Chief Executive Officer from March 2004 to June 2005, was paid for the majority of the 2005 fiscal year unlike the previous fiscal year in which he was compensated only for the last quarter. Mr. Alsenas received compensation of A$696,358 (excluding equity) through June 16, 2005, when he resigned as our Chief Executive Officer and director. We anticipate that employee benefit expenses for the 2006 fiscal year will be approximately A$1,690,000.

Consulting fee expenses
Consulting fee expenses decreased to A$1,607,892 for the year ended June 30, 2005 from A$1,706,809 for the year ended June 30, 2004, a decrease of A$98,917, or 5.8%. The decrease in consulting fees was primarily due to a reduction in consulting fees paid to directors for additional consulting services amounting to A$246,860. The fees paid to our research and development consultants declined by A$27,963 in the 2005 fiscal year. This decrease was partially offset by A$60,000 paid to the Company Secretary. A new consultant was also engaged in the United States to whom we paid A$115,906 in the 2005 fiscal year. We anticipate that consulting fee expenses for the 2006 fiscal year will be substantially similar to those for the 2005 fiscal year.

Corporate compliance expenses
Corporate compliance expenses increased to A$562,123 for the year ended June 30, 2005 from A$419,708 for the year ended June 30, 2004, an increase of A$142,415, or 33.9%. The increase in corporate compliance expenses is attributable to additional Securities and Exchange Commission filing requirements following the filing of the registration statement in connection with the June 2004 private placement in the United States and additional listing fees. We anticipate that corporate compliance expenses for the 2006 fiscal year will be substantially similar to those for the 2005 fiscal year.

Foreign exchange losses
Foreign exchange losses increased to A$1,362,572 for the year ended June 30, 2005 from A$182,768 for the year ended June 30, 2004, an increase of A$1,179,804, or 645.5%. The increase in foreign exchange losses in the 2005 fiscal year is attributable to the significant increase in foreign currency funds because the funds that we received in connection with our June 2004 private placement in the United States were held in U.S. dollars.

Impairment of intangible assets
Impairment of intangible assets was A$10,388,339 for the year ended June 30, 2005. This was a one-off non-cash expense incurred as a result of the consolidated entity’s decision to impair the core intellectual property carrying value to nil recoverable amount based on expected future discounted cash flows. The impairment occurred following the announcement in April 2005 regarding the cessation of the PBT-1 clinical trial due to toxicity issues and the decision to continue research into PBT-2 as the lead compound. The core intellectual property related primarily to externally acquired patents for PBT-1.

Other expenses from ordinary activities
Other expenses from ordinary activities increased to A$1,402,210 for the year ended June 30, 2005 from A$758,772 for the year ended June 30, 2004, an increase of A$643,438, or 84.8%. The increase in expenses from ordinary activities is primarily due to an increase in office overheads of A$141,863 associated with the establishment of an office in the United States in August 2004 and the travel expenses between the United States and Australia of A$141,863 by the consolidated entity’s U.S. based director and Chief Executive Officer prior to his resignation in June 2005. Other expenses also increased due to the increased cost of insurance associated with clinical trials of A$40,530 and the increase in the cost of directors and officers insurance of A$96,304. We also incurred additional marketing costs of A$212,461 when consultants were engaged in the United States following the June 2004 private placement. Our office occupancy cost in Australia also increased by A$85,682.

Year ended June 30, 2004 compared to year ended June 30, 2003
Revenues from ordinary activities
Revenues from ordinary activities increased to A$2,321,227 for the year ended June 30, 2004 from A$1,816,478 for the year ended June 30, 2003, an increase of A$504,749, or 27.8%. Revenues in the year ended June 30, 2004 consisted of A$211,327 interest income, A$647,400 government grant income, and A$1,462,500 received under the licensing and research collaboration that we entered into with Schering A.G. and Neurosciences Victoria Ltd. in March 2003. Revenues in the year ended June 30, 2003 consisted of A$111,686 interest income, A$967,000 government grant income, A$231,304 reimbursements attributable to an agreement with the Bank of New York (under which 50% of the costs associated with the NASDAQ listing were reimbursed) and A$506,250 under our licensing and research collaboration with Schering A.G. and Neurosciences Victoria Ltd. The increase in revenues is attributable to our collaboration with Schering A.G. and Neurosciences Victoria Ltd. which was in force during the entire 2004 fiscal year, as well as the increase in interest income arising primarily from the funds we received in June 2004 in connection with our US$20 million private placement. We estimate that our revenues in the 2005 fiscal year will consist of A$260,000 interest income, A$920,660 government grant income and A$843,750 under our collaboration with Schering A.G. and Neurosciences Victoria Ltd. Initially, we entered into three agreements in connection with our collaboration with Schering A.G and Neurosciences Victoria Ltd, one of which expired in fiscal year 2004. We are currently renegotiating the remaining two agreements. We expect that our revenues under the agreements being renegotiated in connection with such collaboration will be substantially the same as if the existing two agreements continued in full force and effect, however the new agreements could result in a different level of revenues in fiscal year 2005 than estimated.

Depreciation and amortization expenses
Depreciation and amortization expenses remained substantially consistent at A$1,195,006 for the year ended June 30, 2004 compared to A$1,185,973 for the year ended June 30, 2003. 34

Patents, research and development expenses
Patents, research and development expenses increased to A$5,232,581 for the year ended June 30, 2004 from A$1,861,295 for the year ended June 30, 2003, an increase of A$3,371,286, or 181.1%. The increase in expenses is attributable to expenses of A$1,873,125 incurred in connection with the licensing and research collaboration we entered into with Schering A.G. and Neurosciences Victoria Ltd. and pre-clinical trial fees of A$1,984,181 in connection with the new government START grant that commenced in September 2003. See Item 5C. "Operating“Operating and Financial Review and Prospects - Research and Development, Patents and Licenses". We expect that our patents, research and development expenses will increase in the 2005 fiscal year to approximately A$17,000,000, primarily due to an increase in research expenses for clinical development as PBT-1 may advance into Phase II and III trials and PBT-2 is expected to begin Phase I clinical trials. Licenses.”

Legal expenses
Legal expenses increased to A$1,650,467 for the year ended June 30, 2004 from A$848,660 for the year ended June 30, 2003, an increase of A$801,807, or 94.5%. The increase in legal expenses was primarily due to the settlement of the dispute with P.N. Gerolymatos S.A for which a provision of A$971,764 was made in the 2004 fiscal year.

41

Employee benefits expense
Employee benefits expenses increased to A$1,060,730 for the year ended June 30, 2004 from A$760,980 for the year ended June 30, 2003, an increase of A$299,750, or 39.4%. The increase in employee benefits expenses was primarily due to an increase in staff from six persons to 12 persons. The increase in staff in fiscal 2004 was due to the increase of research and development for our new lead product candidate PBT-2 during such period, in addition to our earlier product PBT-1, and our move towards commercialization.

Consulting fee expenses
Consulting fee expenses increased to A$1,706,809 for the year ended June 30, 2004 from A$567,730 for the year ended June 30, 2003, an increase of A$1,139,079, or 200.6%. The increase in consulting fee expenses was primarily due to a A$777,721 increase in fees paid (in cash, shares and options) to Professor Ashley Bush under his new contract (see Item 5B. "OperatingB. “Operating and Financial Review and Prospects - Liquidity and Capital Resources"Resources”) as well as an increase in directors'directors’ fees. In the 2003 fiscal year we engaged the outside expertise of Mercer Human Resources to determine the appropriate level of compensation for directors. This resulted in an increase in directors'directors’ fees of A$467,746 (consisting of part cash and 249,999 ordinary shares valued at A$120,000) during the year ended June 30, 2004 to bring the directors fees into line with industry standards. These increases are partially offset by a A$106,388decrease in consulting fees paid to other various consultants in the year ended June 30, 2004, primarily due to a decrease in the activities of our scientific advisory boardScientific Advisory Board and scientific commercial optimization group, the latter of which was disbanded in 2003 because it was not providing our company the advice it required, and in the 2003 fiscal year we received services from a number of one-off consultants that were no longer required in fiscal 2004. 35

Corporate compliance expenses

Revenues in the in year ended June 30, 2003 consisted of A$945,250 government research grants, A$111,686 interest income, A$253,054 reimbursements attributable to an agreement with the Bank of New York (whereby 50% of the costs associated with the NASDAQ listing were reimbursed) and A$506,250 received under the licensing and research collaboration we entered into with Schering A.G. and Neurosciences Victoria Ltd. in March 2003. Revenues in year ended June 30, 2002 consisted of A$567,250 from government research grants and A$226,720 of interest income. Depreciation and amortization expenses Depreciation and amortization expenses increased to A$1,185,973 for the year ended June 30, 2003 from A$1,160,595 for the year ended June 30, 2002, an increase of A$25,378 or 2.2%. The increase in expenses is attributable to the depreciation of the equipment purchased during the year ended June 30, 2003. Patents, research and development expenses Patents, research and development expenses decreased to A$1,861,295 for the year ended June 30, 2003 from A$2,498,486 for the year ended June 30, 2002, a decrease of A$637,191, or 26%. The decrease in expenses is attributable to a reduction in our expenditure on phase II human clinical trials of PBT-1 (which concluded in early 2002) and a reduction in the amounts paid to certain of our research partners (including the effect of the appreciating of the Australian dollar on certain of these payments which are contracted in U.S. dollars), as well as the acquisition of additional patents that were charged to expense. Legal expenses Legal expenses decreased to A$848,660 for the year ended June 30, 2003 from A$923,816 for the year ended June 30, 2002, a decrease of A$75,156, or 9%. The decrease in 36 legal expenses was primarily due to a reduction in legal costs associated with patent litigation and in prosecuting patent claims. Employee benefits expense Employee benefits expenses increased to A$760,980 for the year ended June 30, 2003 from A$378,853 for the year ended June 30, 2002, an increase of A$382,127, or 101%. The increase in employee benefits expenses was primarily due to an increase in key employees from four employees as at June 30, 2002 to six employees as at June 30, 2003. Consulting fee expenses Consulting fee expenses decreased to A$567,730 for the year ended June 30, 2003 from A$604,873 for the year ended June 30, 2002, a decrease of A$37,143, or 6%. The decrease in consulting fee expenses was primarily due to an increase in employees, reducing the cost of outside consultants. Corporate compliance expenses Corporate compliance expenses increased to A$395,604 for the year ended June 30, 2003 from A$339,383 for the year ended June 30, 2002, an increase of A$56,221, or 16.6%. The increase in corporate compliance expenses is primarily attributable to the costs related to our listing on the NASDAQ SmallCap Market in September 2002. Other expenses from ordinary activities Other expenses from ordinary activities increased to A$ 781,074 for the year ended June 30, 2003 from A$336,431 for the year ended June 30, 2002, an increase of A$444,643, or 132%. The increase in expenses from ordinary activities is primarily due to the increase in operations, which resulted in increases in rental expense, office overhead costs, marketing expenses (primarily in the United States) and overseas travel expense. Much of this additional expenditure was due to our increasing discussions with potential corporate partners and our listing on the NASDAQ SmallCap Market.

Management believes inflation has not had a material impact on our company'scompany’s operations or financial condition and that our operations are not currently subject to seasonal influences.
B. LIQUIDITY AND CAPITAL RESOURCES Liquidity and Capital Resources

From inception until our initial public offering in March 2000 we financed our operations primarily through borrowings from two of our directors, which were repaid from the proceeds of such offering. Since our initial public offering we have financed our operations primarily through sales of equity securities, 37 proceeds from the exercise of options, government grants, licensing and research collaborations and interest earned on investments.

In March 2003, we completed the conversion of our 7,289,310 outstanding listed options into ordinary shares. As a result of the conversion, we received approximately A$3.5 million in net proceeds, which funds were added to our working capital.

In September 2003, we raised an additional approximately 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 approximately US$20 million before issuance costs (A$($26.4 million net of issuance costs) in a private placement in the United States, 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 4,000,000 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 3,000,000 ADRs at an exercise price of US$8.00 per ADR. Should these warrants be exercised in full, we would raise an additional US$24 million. CashTo date, no warrants have been exercised.

In December 2004, we raised approximately A$4.7 million in net proceeds through the exercise of options to purchase 9,506,666 ordinary shares having an exercise price of A$0.50 per share.

We had A$21,453,304 of cash and cash equivalents totaledat June 30, 2005, compared to A$29,580,398 at June 30, 2004, compared to A$3,463,783 at June 30, 2003. 2004.

The increase in payments from the year ended June 30, 20032004 to the year ended June 30, 2004 consisted primarily2005 was due to the acceleration of the increase in directors' fees, costs associated with the preclinical trials, expenses associated withresearch and development for our collaboration with Schering A.GPBT-1 and Neurosciences Victoria Ltd. and the increase of costs associated with Professor Ashley Bush's new consultancy agreement.PBT-2 product candidates. During the years ended June 30, 2005, 2004 2003 and 2002,2003, our payments to suppliers and employees were offset by government grants of A$532,283, A$909,946 A$836,335 and A$843,714,836,575, respectively, and interest income of A$883,583, A$176,845 A$106,835 and A$242,215,106,835, respectively.

The increasehigher expenditures in the 2004 fiscal year wascompared to other years is primarily the result of fit-out costs associated with the move to our new premises. offices in Parkville, Victoria, Australia in 2004.

Net cash provided by financing activities was A$4,704,757, A$31,781,165 A$3,569,792 and A$580,3453,569,792 during the years ended June 30, 2005, 2004 and 2003, and 2002, respectively. Cash flows from financing activities during the year ended June 30, 2005 reflected the exercise of options into ordinary share capital. Cash flows from financing activities during the year ended June 30, 2004 reflected net proceeds of A$4,675,019 from a private placement in September 2003, net proceeds of A$26,352,147 from a private placement of 38 our ADRs to institutional and professional investors in the United States in June 2004 and net proceeds of A$757,166 from the exercise of our publicly traded options.

Capital expenditures for equipment are being depreciated on a straight-line basis over the estimated useful lives of three to 14 years, with a net balance at June 30, 20042005 of A$180,971.166,214. We currently do not have significant capital spending requirements, but we expect to continue to engage in capital spending consistent with anticipated growth in our operations and personnel.

As of June 30, 2004,2005, our principal commitments consisted of obligations under our agreements with Neurosciences Victoria Ltd. (in connection with our collaboration with Neurosciences Victoria Ltd. and Schering A.G.) and Professor Ashley Bush. In accordance with the terms of our current project agreements with Neurosciences Victoria Ltd. in connection with such collaboration, we are obliged to spend A$759,375 on researchBush and development activities at the University of Melbourne during the nine months ending March 31, 2005, however we are currently renegotiating our contracts with Neurosciences Victoria Ltd. and such amount may change.Mr. Geoffrey Kempler. Under the ten year contract we recently entered into with Professor Ashley Bush in January, 2004, effective as of February 1, 2003, we agreed to pay Professor Bush a consulting fee of US$100,000 per year increasing on the anniversary of the agreement by the U.S. consumer price index. We also agreed to issue to Professor Bush 1,650,000 ordinary shares of(of which 825,000 were issued during the 2004 fiscal year and 825,000 were issued in August 2005) and to grant Professor Bush options to purchase 824,000825,000 ordinary shares at an exercise price $0.50A$0.50 per share of(of which options to purchase 412,000 ordinary shares were granted during the 2004 fiscal year. year and 413,000 were granted in August 2005). On June 15, 2005, we entered into an agreement with Geoffrey Kempler in connection with his appointment as our Chief Executive Officer. Under this contract, we agreed to pay Mr. Kempler A$367,000 per annum plus superannuation, a A$100,000 bonus upon satisfactory completion of a successful Phase I trial for PBT-2 and an additional A$100,000 upon satisfactory completion of a proof of study concept study for PBT-2. Under the agreement with Mr. Kempler, we are required to continue to remunerate him in accordance with its terms until June 1, 2010 if he terminates the contract for good reason or the consolidated entity terminates it without cause.

On July 28, 2004, we and The General Hospital Corporation of Massachusetts settled all outstanding litigation with P.N. Gerolymatos S.A., or P.N.G., regarding the exploitation rights to certain patents relating to pharmaceutical compositions and uses of clioquinol, or PBT-1. Pursuant to the settlement agreement, all patent oppositions in Europe and Australia were withdrawn and the law suits then pending before the U.S. District Court for the District of Columbia and the Court of Athens in Greece have been dismissed. Under the settlement agreement, we and P.N.G. agreed to recognize the rights of each other to develop clioquinol in our respective territories. As a result of the settlement agreement, we now hold the rights to selected uses of clioquinol and pharmaceutical compositions in the United States and selected uses of clioquinol in Japan, while P.N.G. holds certain patent rights on the uses of clioquinol for Europe and other territories. Under the settlement agreement, we issued 1,350,000 of our ordinary shares to P.N.G., which are being held in escrow for 12 months, and made a payment of US$150,000 to P.N.G. Such settlement in the total value of A$971,764 was expensed in fiscal year 2004 (see Note 9 to the financial statements). Under the settlement agreement we also agreed to pay a sales royalty to P.N.G. on sales of PBT-1 in the United States and Japan and we are entitled to receive a percentage of P.N.G.’s income on sales of PBT-1 in the other territories. In April 2005, we announced to the market our decision not to proceed with supporting the initiation of the PLACQUE study evaluating PBT-1.

We also have a commitment under a three year lease for our new principal office that we moved to in June 2004. The total lease commitment over the three year period is A$306,781. Under our agreement with Kendle, a director-related company, we are required to pay A$1,280-A$1,520 per day for their services in connection with the commercialization of our technology. In fiscal year 2004, we paid Aroma Science, a director-related company, on arms length commercial rates, for computer, administration and meeting facilities. This agreement ended following our move to our new premises. We also pay Malvern Administrative Services Pty Ltd. A$15,000 per month under an ongoing agreement for administrative, accounting, company secretarial services and corporate advice.

We believe our existing cash and cash equivalents as well as anticipated cash flow from government grants, a licensing and research collaboration agreementinterest income and potential option exercises will be sufficient to support our current operating plan to December 31, 2005;November 30, 2006; 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; 39 o

·costs and timing of obtaining regulatory approvals;

·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

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

In March 2005, we commenced a series of Phase I clinical trials for our current principal product candidate PBT-2 at a facility associated with the Utrecht University Hospital in Utrecht, the Netherlands. On November 7, 2005, we announced the successful completion of the Phase I trial for PBT-2, a double blind, placebo-controlled single dose escalation study, conducted on 55 healthy, male volunteers between the ages of 18 and 50, which was designed to evaluate the safety, tolerability and pharmacokinetics of PBT-2. Data from the study shows that PBT-2 was well tolerated with little difference in the incidence of adverse events between those receiving PBT-2 and those receiving the placebo. Additionally, the pharmacokinetic analysis demonstrated that the drug exposure increased predictably and in a linear manner, both of which are strong characteristics for a central nervous system drug. Concurrent findings in a pre-clinical mouse model indicate that PBT-2 passes into the brain of mice with more extensively than its predecessor, PBT-1. We have also completed three out of four stages of a second Phase I multi-dose escalation safety clinical trial of PBT-2 in elderly, healthy, male and female volunteers. We anticipate completing the final dosing stage in December 2005. In addition, the preclinical toxicology studies and GMP manufacturing development required for Phase II and Phase III clinical studies of PBT-2 are concurrently underway. We anticipate that expenditures for the Phase I program for PBT-2 will amount to A$700,000, however such expenditures may adjust due to numerous factors. For information on such factors, see Item 5.C. "Operating and Financial Review and Prospects - Research and Development, Patents and Licenses." We expect to fund such expenditures from our working capital.

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 current principal pharmaceutical product candidates;candidate. In addition, we will require additional funds to pursue regulatory clearances, and o the progressdefend our intellectual property rights, establish commercial scale manufacturing facilities, develop marketing and number ofsales 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 programs in development. and development activities, which could have a material adverse effect on our business, financial condition and results of operations.

Conditions in Australia
We are incorporated under the laws of, and our principal offices and research and development facilities are located in, the Commonwealth of Australia. Therefore, we are directly affected by political and economic conditions in Australia.
C. RESEARCH AND DEVELOPMENT, PATENTS AND LICENSES Research and Development, Patents and Licenses
Our primary activity since incorporation in 1997 has been the acquisition and development of patents as well as research and development of our core technology. Research and development expenses amounted to A$7,687,596, A$5,232,581 A$1,717,770 and A$1,827,5361,717,770 during the years ended June 30, 2005, 2004 2003 and 2002,2003, respectively. In addition to these expenses, A$143,525 and A$670,950 was spent in relation to patent costs during the yearsyear ended June 30, 2003 and 2002, respectively.2003. We did not incur any costs classified as patent costs during the yearyears ended June 30, 2005 or 2004. Costs associated with patent applications and defense of patent applications are classified as legal expenses.

Our patents, research and development expenses consist primarily of compensation and related costs for research and development personnel, expenses for testing facilities and payments under our research agreements. Such costs are charged to operations as incurred. Research and development expenses also include costs associated with the acquisition and development of patents subsequent to December 1999. We do not maintain accounting systems to accurately track research and development costs on an individual project basis because a significant portion of our historic research and development expenses benefited our two major research and development projects, and therefore were not tracked individually by project; rather, we tracked these costs by the type of costs incurred. Such costs are charged to operations as incurred. See Note 1(d)1(e) to the financial statements.

The development of a clinical compound includes a number of steps and phases, including pre-clinical and clinical testing. Despite best efforts to plan and manage research and development, the actual timing and cost for completion of each step involved in the development of a clinical compound depends on many factors. The decision to proceed to the next step of a multi-stage development program is based on the outcome of multiple variables of any current stage and previous stages (including tolerability, specific toxicities, overall safety, pharmacokinetics and efficacy) and may be influenced by outside factors (including the competitive commercial environment and regulatory environment).  Government or regulatory authorities, clinicians and other experts may, following their review of the results of a previous step, require that an initial development program be included orrevised in order to strengthen the safety, efficacy and/or commercial understanding and potential of the compound, which could result in changes in the cost, duration, prioritization and even outcome of a development program.  Furthermore, the required duration of treatment in clinical trials has an impact on the duration of a development program for a therapeutic agent and can vary considerably, from less than a month (for example, antibiotics) to several years (for example, treatments requiring long-term outcome measures).  An appropriate duration of treatment in clinical trials with our MPACs is yet to be confirmed and will depend on future clinical results, as well as discussions with regulatory authorities.  Once the duration of such treatment has been determined, the question whether the development stages must be undertaken sequentially or may be undertaken in parallel can be addressed.  Due to the numerous variables and the uncertain nature of the development of a clinical compound, we are not able to reasonably estimate the nature, timing and costs of the future expenditures necessary to complete our research and development projects, the anticipated completion dates of each project, and when material net cash flows from our research and development programs will commence.

In March 2003, we announced our first major licensing and research collaboration with Schering A.G., a major international pharmaceutical company, and Neurosciences Victoria Ltd..Ltd. Under suchthis collaboration, we, through our contractor the University of Melbourne, undertook specific research and development projects, and Schering A.G. is providing to us funding offunded up to A$2.7 million of our research and development costs over the life of specified researchthe projects and development projects that we will conduct, withagreed to pay additional milestone payments and royalties from discoveries. Despite the arrangement between the parties, the early results of the research and development did not support the continuation of the collaboration past June 30, 2005. As a result, the parties concluded this collaboration as of June 30, 2005. See Item 4A., "Information “Information on the Company - History and Development of the Company."

We have also identified and provisionally patentedfiled an international patent application directed to a novel target for an Alzheimer's disease vaccine. The Commonwealth Government of Australia provided us with a A$227,252 BIF grant for the initial proof of concept stage of this research. The research under this BIF grant finished at the end of January 2005 following the completion of certain project milestones stipulated in the grant, demonstrating that a mouse could generate antibodies that preferentially recognize dimerized βAmyloid. We are collaboratingcurrently negotiating a contractual agreement with Prima Biomed Ltd., a publicly traded Australian biotech company,to undertake the characterization and usescale-up of prospective antibody candidates that were identified during the initial proof of concept stage for testing in future passive vaccine trials in Alzheimer's disease model mice. We will be utilizing the resources of Prima, the Austin Research institute,Institute, the University of Melbourne and the Mental Health Research Institute to pursue this therapeutic approach. The research is investigating the feasibility of developing a vaccine to prevent the onset or progression of Alzheimer's. The research is assessingwill assess the ability of the immune system to selectively produce specific antibodies which target the "toxic linked"“toxic linked” forms of beta amyloid (not `normal' beta amyloid) associated with the pathology of theAlzheimer’s disease, as an effective Alzheimer's treatment. The Commonwealth of Australia government has provided a A$227,252 BIF granttreatment for this work. the disease.
We announced on July 26, 2001 that we were granted a START grant from the Australian IR&D Board in the amount of A$1.74 million to expand our core intellectual property for drug treatment of neuro-degenerative diseases. Under the terms of the grant we received A$1.71.4 million during the three year period commencing January 1, 2001, for up to 50% of the project 40 costs related to our development of a treatment for Alzheimer'sAlzheimer’s disease. The grant was payable on the achievement of each of six milestones and we received the final payment under the START grant in October 2003.

We announced on February 18, 2004 that we were granted a second START grant from the Australian IR&D Board in the amount of A$1.35 million to take our second generation drug candidate for Alzheimer’s disease, PBT-2, through safety testing and Phase I clinical trials. Under the terms of the grant we are to receive A$1.35 million during the two-year period commencing September 1, 2003, for up to 50% of the project costs related to the toxicology testing program and early human trials. The second START grant completed advance toxicology in December 2004, commenced Phase I clinical trials in March 2005 and is expected to conclude the Phase I trials in December 2005. At June 30, 2005, we had claimed A$1.07 million under this grant. The quarterly report for the period ending September 2005 is yet to be filed.

On May 7, 1999, we entered into a patent assignment and license agreement with the University of Melbourne. The agreement provided for the assignment of various patents and patent rights to us. In consideration of the assignment of the patents, we were required to make certain payments to the University of Melbourne and to pay a royalty of 1.5% on the net price of products sold utilizing such patents. In addition we must also pay the lesser of 1.5% of the net invoice price of products sold or 10% of royalties received from any license or sub-licensee we appoint to utilize the patents.

Under the terms of a research funding and intellectual property assignment agreement dated December 1, 2000 between us and the University of Melbourne, we arewere required to pay the University for research projects an agreed minimum of A$297,000 (inclusive of goods and services tax), each year for a period of three years from December 1, 2000. Since the natural expiration of suchthis agreement, the parties have continued to conduct research and perform all other acts and obligations in accordance with the terms and conditions of the agreement as if it had remained in full force and effect, and in addition have incorporated into such agreement the projects under the agreements we entered into with Neurosciences Victoria Ltd. in March 2003 (see Item 4A. "Information on the Company - History and Development of the Company"). We are currently negotiating the renewal of oura second research funding and intellectual property assignment agreement, withwhich is deemed to have commenced from the natural expiry of the previous agreement and expires in December 2006. The agreement provides for an annual determination of the research budget. During the period from July 2004 to June 2005, we provided A$600,000 (exclusive of goods and service tax) to the University of Melbourne. We also provided the University of Melbourne (see Item 10C. "Additional Information - Material Contracts"). Although we have every intention of continuingan additional A$1,012,500 during the 2005 fiscal year in research funding in connection with our relationshiplicensing and research collaboration with the University of MelbourneSchering A.G. and Mental Health Research Institute ofNeurosciences Victoria to support our drug screening program, we cannot give any assurance that this can be or will be undertaken.

Under NASDAQ rulesMarketplace Rules promulgated pursuant to the Sarbanes-Oxley Act of 2002, byas of July 31, 2005, a majority of our Board of Directors must qualify as independent directors within the meaning of the NASDAQ Marketplace Rules and we will be required toour audit committee must have at least three members and be comprised only of independent directors, each of whom satisfies the respective “independence” requirements of NASDAQ and the Securities and Exchange Commission. However, under a recent amendment to the NASDAQ Marketplace Rules, foreign private issuers, such as our company, may follow certain home country corporate governance practices without the need to seek individual exemptions from NASDAQ. Instead, a foreign private issuer must provide NASDAQ with a letter from outside counsel in its home country certifying that to the extent that the issuer's corporate governance practices is not in accordance with NASDAQ Marketplace Rules, it follows home country law and practice. On March 30, 2005, we provided NASDAQ with a notice of non-compliance with respect to the NASDAQ requirement to maintain a majority of independent directors, as defined under the NASDAQ Marketplace Rules, and the requirement that audit committee members meet the independence standard of NASDAQ. Instead, we follow Australian law and practice which does not require a company to appoint a certain number of independent directors to its board of directors or audit committee. However, under the ASX Best Practice Guide, the ASX recommends, but does not require, that a ASX-listed company have a majority of independent directors on its board of directors and that the audit committee be comprised of independent directors, within the meaning of the rules of the ASX. We currently comply with the foregoing recommendations of the ASX Best Practice Guidance. In addition, in accordance with the rules of the Securities and Exchange Commission, we have the mandated three independent directors, as defined by such rules, on our Audit Committee. Mr.See below in this Item 6C. "Directors, Senior Management and Employees - Board Practices - NASDAQ Marketplace Rules and Home Country Practices."

Our Board of Directors has determined that each of Messrs. Brian Meltzer, is the only director that currentlyGeorge Mihaly and Peter Marks qualifies as an independent director under the ASX, NASDAQ Stock Market and Securities and Exchange Commission requirements.

The agreement also provides us with the non-exclusive right to use materials, substances and information that were used by GHC in research sponsored by us. In consideration of the license, we are required to pay GHC royalties of 1.5% of the net sales price of products sold utilizing patents exclusively licensed to us. We are also required to pay certain advance milestone payments, to be reduced from the royalties. In addition to the royalties we are obligated to pay GHC 1.5% of any and all non-royalty payments, including license fees received from our affiliates. Each party to the agreement may terminate the agreement if the other party defaults in its materials obligations and does not remedy the default within sixty days after notice is given. GHC can terminate the licenses and rights granted to us under the agreement in any country in the event that after the first commercial sale in that country there will be a continuous one year period in which no products are sold. On March 15, 2004, the exclusive license was amended so that we are required to pay GHC the royalties payable to it for any future exploitation of rights to certain U.S. patents relating to PBT-1 regardless of the inventorship determination, as required under the settlement agreement among us, P.N.G. and GHC.

Under this collaboration, we, through our contractor the University of Melbourne, undertook specific research and A$537,327, respectively. In March 2003, we announced our first major licensingdevelopment projects, and research collaboration with Schering A.G., a major international pharmaceutical company, and Neurosciences Victoria Ltd. Under such collaboration, Schering A.G. is providing to us funding of funded up to A$2.7 million of our research and development costs over the life of specified researchthe projects and development projects that we will conduct, withagreed to pay additional milestone payments and royalties from discoveries. Despite the arrangement between the parties, the early results of the research and development did not support the continuation of the collaboration past June 30, 2005. As a result, the parties concluded this collaboration as of June 30, 2005. See Item 4A. "Information, “Information on the Company - History and Development of the Company."

We entered into a consulting agreement dated January 17, 2000 with Professor Ashley Bush for the provision of research and development services relating to inventions and treatments for diseases caused by metal-mediated oxidative stress, which expired in January 2003. On January 8, , 2004, we entered into a new consulting agreement with Professor Bush, , under which Professor Bush agreed to provide us with consulting services for a period of ten years. In consideration of his services, we agreed to pay Professor Bush an annual consulting fee of US$100,000, to issue to Professor Bush 1,650,000 ordinary shares of(of which 825,000 ordinary shares were issued during the 2004 fiscal year and 825,000 ordinary shares were issued during the 2006 fiscal year), and to grant Professor Bush options to purchase 824,000825,000 ordinary shares at an exercise price $0.50A$0.50 per share of(of which options to purchase 412,00 ordinary shares were granted during the 2004 fiscal year. 59 year and 413,000 options were granted during the 2006 fiscal year).

Under the settlement agreement, we agreed to pay a sales royalty to P.N.GP.N.G. on the sales of PBT-1 in the United States and Japan, and we are entitled to receive a percentage of P.N.G.'s’s income on sales of PBT-1 in the other territories. See Item 8A., "Financial “Financial Information - Financial Statements and Other Financial Information - Legal Proceedings."
D. EXCHANGE CONTROLS Exchange Controls
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, in certain circumstances 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.Treasurer. 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 outstandingthe shares (or elsein any company having total assets of A$50 million or more. In addition, a foreign person may not acquire shares in a company having total assets of A$50 million or more if, as a result of that acquisition, the total holdings of all foreign persons and their associates will exceed 40% in aggregate without the approval of the Australian Treasurer. If the necessary approvals are not obtained, the Treasurer may make an order requiring the acquirer to dispose of thosethe shares it has acquired 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. At present, we do not have total assets of A$50 million.

73

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;50,000,000; or (ii) any direct or indirect ownership interest in Australian residential real estate. 60

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'snon-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.
E. TAXATION Taxation
Australian Tax Consequences

In this section we discuss the material Australian tax considerations that apply to non-Australian tax residents with respect to the acquisition, ownership and disposal by the absolute beneficial owners of ADSs, which are evidenced by ADRs. This discussion is based upon existing Australian tax law as of the date of this annual report, which is subject to change, possibly retrospectively. This discussion does not address all aspects of Australian income tax law which may be important to particular investors in light of their individual investment circumstances, such as ADSs or shares held by investors subject to special tax rules (for example, financial institutions, insurance companies or tax exempt organizations). In addition, this summary does not discuss any foreign or state tax considerations, other than stamp duty. Prospective investors are urged to consult their tax advisors regarding the Australian and foreign income and other tax considerations of the purchase, ownership and disposition of the ADSs or shares.
Nature of ADRs for Australian Taxation Purposes
ADSs held by a U.S. holder will be treated for Australian taxation purposes as held under a `bare trust'‘bare trust’ for such holder. Consequently, the underlying ordinary shares will be regarded as owned by the ADS holder for Australian income tax and capital gains tax purposes. Dividends paid on the underlying ordinary shares will also be treated as dividends paid to the ADS holder, as the person beneficially entitled to those dividends. Therefore, in the following analysis we discuss the tax consequences to non-Australian resident holders of ordinary shares which, for Australian taxation purposes, will be the same as to U.S. holders of ADSs. 
74

Taxation of Dividends
Australia operates a dividend imputation system under which dividends may be declared to be `franked'‘franked’ to the extent of tax paid on company profits. Fully franked dividends are not subject to dividend withholding tax. Dividends payable by our company to non-Australian resident stockholders will be subject to dividend withholding tax, to the extent the dividends are unfranked. Dividend withholding tax will be imposed at 30%, unless a stockholder is a resident of a country with which Australia has a double taxation agreement. Under the provisions of the 61 current Double Taxation Convention between Australia and the United States, the Australian tax withheld on unfranked dividends paid by us to which a resident of the United States is beneficially entitled is generally limited to 15% if the U.S. resident holds less than 10% of the voting rights of our company, unless the shares are effectively connected to a permanent establishment or fixed base in Australia through which the stockholder carries on business or provides independent personal services, respectively. Where the U.S. resident holds 10% or more of the voting rights of our company, the withholding tax rate is reduced to 5%.
Tax on Sales or other Dispositions of Shares - Capital Gains Tax
Non-Australian resident stockholders will not be subject to Australian capital gains tax on the gain made on a sale or other disposal of our shares, unless they, together with associates, hold 10% or more of our issued capital at any time during the five years before the disposal of the shares. 
If a non-Australian resident stockholder did own a 10% or more interest, that stockholder would be subject to Australian capital gains tax to the same extent as Australian resident stockholders. The Australian Taxation Office maintains the view that the Double Taxation Convention between the United States and Australia does not limit Australian capital gains tax. Australian capital gains tax applies to net capital gains at a taxpayer'staxpayer’s marginal tax rate but for certain stockholders a discount of the capital gain may apply if the shares have been held for 12 months or more. For individuals, this discount is 50%. Net capital gains are calculated after reduction for capital losses, which may only be offset against capital gains. 
Tax on Sales or other Dispositions of Shares - Stockholders Holding Shares on Revenue Account
Some non-Australian resident stockholders may hold shares on revenue rather than on capital account, for example, share traders. These stockholders may have the gains made on the sale or other disposal of the shares included in their assessable income under the ordinary income provisions of the income tax law, if the gains are sourced in Australia.
Non-Australian resident stockholders assessable under these ordinary income provisions in respect of gains made on shares held on revenue account would be assessed for such gains at the Australian tax rates for non-Australian residents, which start at a marginal rate of 29%. Some relief from the Australian income tax may be available to such non-Australian resident stockholders under the Double Taxation Convention between the United States and Australia, for example, because the stockholder does not have a permanent establishment in Australia.
75

To the extent an amount would be included in a non-Australian resident stockholder'sstockholder’s assessable income under both the capital gains tax provisions and the ordinary income provisions, the capital gain amount would generally be reduced, so that the stockholder would not be subject to double tax on any part of the income gain or capital gain.
Dual Residency
If a stockholder were a resident of both Australia and the United States under those countries'countries’ domestic taxation laws, that stockholder may be subject to tax as an Australian resident. If, however, the stockholder is determined to be a U.S. resident for the purposes of the 62 Double Taxation Convention between the United States and Australia, the Australian tax would be subject to limitation by the Double Taxation Convention. Stockholders should obtain specialist taxation advice in these circumstances.
Stamp Duty
Any transfer of shares through trading on the Australian Stock Exchange, whether by Australian residents or foreign residents are not subject to stamp duty within Australia.
Australian Death Duty
Australia does not have estate or death duties. No capital gains tax liability is realized upon the inheritance of a deceased person'sperson’s shares. The disposal of inherited shares by beneficiaries, may, however, give rise to a capital gains tax liability.
Goods and Services Tax
The issue or transfer of shares will not incur Australian goods and services tax and does not require a stockholder to register for Australian goods and services tax purposes.

United States Federal Income Tax Consequences

The following is a summary of certain material U.S. federal income tax consequences that generally would apply to U.S. Holders who hold ADRs as capital assets. This summary is based on the United States Internal Revenue Code of 1986, as amended, or the Code, Treasury regulations promulgated thereunder, judicial and administrative interpretations thereof, the bilateral taxation convention between Australia and the United States, or the Tax Treaty, all as in effect on the date hereof and all of which are subject to change either prospectively or retroactively. This summary does not address all tax considerations that may be relevant with respect to an investment in ADRs. This summary does not discuss all the tax consequences that may be relevant to a U.S. Holder in light of such holder'sholder’s particular circumstances or to U.S. Holders subject to special rules, including broker-dealers, financial institutions, certain insurance companies, investors liable for alternative minimum tax, tax-exempt organizations, regulated investment companies, non-resident aliens of the United States or taxpayers whose functional currency is not the U.S. dollar, persons who hold the ADRs through partnerships or other pass-through entities, persons who acquired their ADRs through the exercise or cancellation of any employee stock options or otherwise as compensation for their services, investors that actually or constructively own 10% or more of our voting shares, and investors holding ADRs as part of a straddle or appreciated financial position or as part of a hedging or conversion transaction.
76

If a partnership or an entity treated as a partnership for U.S. federal income tax purposes owns ADRs, the U.S. federal income tax treatment of a partner in such a partnership will generally depend upon the status of the partner and the activities of the partnership. A partnership that owns ADRs and the partners in such partnership should consult their tax advisors about the U.S. federal income tax consequences of holding and disposing of ADRs.
This summary does not address the effect of any U.S. federal taxation other than U.S. federal income taxation. In addition, this summary does not include any discussion of state, local or foreign taxation. You are urged to consult your tax advisors regarding the foreign and U.S. federal, state and local tax considerations of an investment in ADRs. 63
For purposes of this summary, the term "U.S. Holder"“U.S. Holder” means an individual who is a citizen or, for U.S. federal income tax purposes, a resident of the United States, a corporation or other entity taxable as a corporation created or organized in or under the laws of the United States or any political subdivision thereof, an estate whose income is subject to U.S. federal income tax regardless of its source, or a trust if (a) a court within the United States is able to exercise primary supervision over administration of the trust, and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) it has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.
Taxation of Dividends
For U.S. federal income tax purposes, U.S. Holders of ADRs will be treated as owning the underlying ordinary shares, or ADSs, represented by the ADRs held by them. TheSubject to the passive foreign investment company rules discussed below, the gross amount of any distributions received with respect to the underlying ordinary shares represented by the ADRs, including the amount of any Australian taxes withheld there from, will constitute dividends for U.S. federal income tax purposes, to the extent of our current and accumulated earnings and profits as determined for U.S. federal income tax principles. You will be required to include this amount of dividends in gross income as ordinary income (see "Tax Law Applicable to Dividends and Long-Term Capital Gain" below).income. Distributions in excess of our earnings and profits will be treated as a non-taxable return of capital to the extent of your tax basis in the ADRs, and any amount in excess of your tax basis will be treated as gain from the sale of ADRs. See "Disposition“Disposition of ADRs"ADRs” below for the discussion on the taxation of capital gains. Dividends will not qualify for the dividends-received deduction generally available to corporations under Section 243 of the Code.
Dividends that we pay in A$, including the amount of any Australian taxes withheld there from, will be included in your income in a U.S. dollar amount calculated by reference to the exchange rate in effect on the day such dividends are received. A U.S. Holder who receives payment in A$ and converts A$ into U.S. dollars at an exchange rate other than the rate in effect on such day may have a foreign currency exchange gain or loss that would be treated as ordinary income or loss. U.S. Holders should consult their own tax advisors concerning the U.S. tax consequences of acquiring, holding and disposing of our ADRs. Any
77

Subject to complex limitations, any Australian withholding tax imposed on such dividends will be a foreign income tax eligible for credit against a U.S. Holder'sHolder’s U.S. federal income tax liability subject to certain limitations set out in the Code (or, alternatively, for deduction against income in determining such tax liability). The limitations set out in the Code include computational rules under which foreign tax credits allowable with respect to specific classes of income cannot exceed the U.S. federal income taxes otherwise payable with respect to each such class of income (see "Tax Law Applicable to Dividends and Long-Term Capital Gain" below).income. Dividends generally will be treated as foreign-source passive income or financial services income for U.S. foreign tax credit purposes. Foreign income taxes exceedingU.S. Holders should note that recently enacted legislation eliminates the credit limitation for the year of payment or accrual may be carried back for two“financial services income” category with respect to taxable years and forward for five taxable years in order to reduce U.S. federal income taxes, subject to the credit limitation applicable in each of such years. Other restrictions onbeginning after December 31, 2006. Under this legislation, the foreign tax credit include a prohibition on the use of the creditlimitation categories will be limited to reduce liability for the U.S. individual“passive category income” and corporation alternative minimum taxes by more than 90%.“general category income.” A U.S. Holder will be denied a foreign tax credit with respect to Australian income tax withheld 64 from dividends received with respect to the underlying ordinary shares represented by the ADRs to the extent such U.S. Holder has not held the ADRs for at least 16 days of the 30-day period beginning on the date which is 15 days before the ex-dividend date or to the extent such U.S. Holder is under an obligation to make related payments with respect to substantially similar or related property. Any days during which a U.S. Holder has substantially diminished its risk of loss on the ADRs are not counted toward meeting the 16-day holding period required by the statute. The rules relating to the determination of the foreign tax credit are complex, and you should consult with your personal tax advisors to determine whether and to what extent you would be entitled to this credit.
Subject to certain limitations, “qualified dividend income” received by a noncorporate U.S. Holder in tax years beginning on or before December 31, 2008 will be subject to tax at a reduced maximum tax rate of 15 percent. Distributions taxable as dividends paid on the underlying shares represented by the ADRs should qualify for the 15 percent rate provided that either: (i) we are entitled to benefits under the income tax treaty between the Tax Treaty or (ii) the ADRs are readily tradable on an established securities market in the United States and certain other requirements are met. We believe that we are entitled to benefits under the Tax Treaty and that the ADRs currently are readily tradable on an established securities market in the United States. However, no assurance can be given that the ADRs will remain readily tradable. The rate reduction does not apply unless certain holding period requirements are satisfied. With respect to the ADRs, the U.S. Holder must have held such ADRs for at least 61 days during the 121-day period beginning 60 days before the ex-dividend date. The rate reduction also does not apply to dividends received from passive foreign investment companies, see discussion below, or in respect of certain hedged positions or in certain other situations. The legislation enacting the reduced tax rate contains special rules for computing the foreign tax credit limitation of a taxpayer who receives dividends subject to the reduced tax rate. U.S. Holders of ADRs should consult their own tax advisors regarding the effect of these rules in their particular circumstances.
Disposition of ADRs
If you sell or otherwise dispose of ADRs, you will recognize gain or loss for U.S. federal income tax purposes in an amount equal to the difference between the amount realized on the sale or other disposition and your adjusted tax basis in the ADRs. Subject to the discussionpassive foreign investment company rules discussed below, under the heading "Passive Foreign Investment Companies," such gain or loss generally will be capital gain or loss and will be long-term capital gain or loss if you have held the ADRs for more than one year at the time of the sale or other disposition. In general, any gain that you recognize on the sale or other disposition of ADRs will be U.S.-source for purposes of the foreign tax credit limitation; losses will generally be allocated against U.S. source income. Deduction of capital losses is subject to certain limitations under the Code.
78

In the case of a cash basis U.S. Holder who receives A$ in connection with the sale or disposition of ADRs, the amount realized will be based on the U.S. dollar value of the A$ received with respect to the ADRs as determined on the settlement date of such exchange. A U.S. Holder who receives payment in A$ and converts A$ into U.S. dollars at a conversion rate other than the rate in effect on the settlement date may have a foreign currency exchange gain or loss that would be treated as ordinary income or loss.
An accrual basis U.S. Holder may elect the same treatment required of cash basis taxpayers with respect to a sale or disposition of ADRs, provided that the election is applied consistently from year to year. Such election may not be changed without the consent of the Internal Revenue Service, or the IRS. In the event that an accrual basis U.S. Holder does not elect to be treated as a cash basis taxpayer (pursuant to the Treasury regulations applicable to foreign currency transactions), such U.S. Holder may have a foreign currency gain or loss for U.S. federal income tax purposes because of differences between the U.S. dollar value of the currency received prevailing on the trade date and the settlement date. Any such currency gain or loss would be treated as ordinary income or loss and would be in addition to gain or loss, if any, recognized by such U.S. Holder on the sale or disposition of such ADRs. Tax Law Applicable to Dividends and Long-Term Capital Gain Dividends received by noncorporate U.S. Holders from certain
Passive Foreign Investment Companies
There is a substantial risk that we are a passive foreign corporations, and long-term capital gain realized by noncorporate U.S. Holders, generally are subject toinvestment company, or PFIC, for U.S. federal income tax atpurposes. Our treatment as a reduced maximum tax rate of 15 percent through December 31, 2008. Dividends received with respect to the underlying ordinary shares represented by the ADRs should qualify for the 15 percent rate. The ratePFIC could result in a reduction does not apply to dividends received 65 from "foreign investment companies," "foreign personal holding company" or "passive foreign investment companies" (see below), or in respect of certain short-term or hedged positions in the ordinary shares or in certain other situations. There are special rules for computing the foreign tax credit limitation of a taxpayer who receives dividends subjectafter-tax return to the rate reduction. U.S. Holders of our ADRs should consult their own tax advisors regardingand may cause a reduction in the implicationsvalue of these rules in light of their particular circumstances. Passive Foreign Investment Companies such securities.
For U.S. federal income tax purposes, we will be consideredclassified as a passive foreign investment company, or PFIC for any taxable year in which either (i) 75 percent75% or more of our gross income is passive income, or (ii) at least 50 percent50% 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, cash is considered to be an asset which produces passive income. Passive income generally includes dividends, interest, royalties, rents, annuities and the excess of gains over losses from the disposition of assets which produce passive income. If we were determined to beAs a PFIC for U.S. federal income tax purposes, highly complex rules would apply to U.S. Holders owning ADRs. Accordingly, you are urged to consult your tax advisors regardingresult of our substantial cash position and the applicationdecline in the value of such rules. Based on our current and projected income, assets and activities,stock, we believe that we are not currently a PFIC nor do we expect to becomebecame a PFIC in 2004 under a literal application of the foreseeable future. However, because the determination of whetherasset test that looks solely to market value.

If we are a PFIC, is based upon the composition of our income and assets from time to time, there can be no assurances that wedividends will not become a PFIC for any future taxable year. If we are treated as a PFIC for any taxable year, then, unless you elect either to treat your investment in ADRs as an investment in a "qualified electing fund", OR a "QEF election", or to "mark-to-market" your ADRs, as described below, dividends would not qualify for the reduced maximum tax rate, discussed above, and: oand, unless you timely elect to “mark-to-market” your ADRs, as described below:

·you will be required to allocate income recognized upon receiving certain dividends or gain recognized upon the disposition of ADRs ratably over the holding period for such ADRs,

79

·the amount allocated to each year during which we are considered a PFIC other than the year of the dividend payment or disposition would be subject to tax at the highest individual or corporate tax rate, as the case may be, in effect for that year and an interest charge would be imposed with respect to the resulting tax liability allocated to each such year,

·the amount allocated to the current taxable year and any taxable year before we became a PFIC would be taxable as ordinary income in the current year, and

·you will be required to make an annual return on IRS Form 8621 regarding distributions received with respect to ADRs and any gain realized on your ADRs.

The PFIC provisions discussed above apply to U.S. persons who directly or indirectly hold stock in a PFIC. Both direct and indirect shareholders of PFICs are subject to the rules described above. Generally, a U.S. person is considered an indirect shareholder of a PFIC if it is:

·A direct or indirect owner of a pass-through entity, including a trust or estate, that is a direct or indirect shareholder of a PFIC,

·A shareholder of a PFIC that is a shareholder of another PFIC, or

·A 50%-or-more shareholder of a foreign corporation that is not a PFIC and that directly or indirectly owns stock of a PFIC.

An indirect shareholder may be taxed on a distribution paid to the direct owner of the PFIC and on a disposition of the stock indirectly owned. Indirect shareholders are strongly urged to consult their tax advisors regarding the application of these rules.

If we cease to be a PFIC in a future year, a U.S. Holder may avoid the continued application of the tax treatment described above by electing to be treated as if it sold its ADRs on the last day of the last taxable year in which we were a PFIC. Any gain would be recognized and subject to tax under the rules described above. Loss would not be not recognized. A U.S. Holder’s basis in its ADRs would be increased by the amount of gain, if any, recognized on the sale. A U.S. Holder would be required to allocate income recognized upon receiving certain dividends or gain recognized upon the disposition of ADRs ratably over thetreat its holding period for suchits ADRs oas beginning on the amount allocated to eachday following the last day of the last taxable year duringin which we were a PFIC.

If the ADRs are considered a PFIC other than the year of the dividend payment or disposition would be subject“marketable stock” and if you elect to tax at the highest individual or corporate tax rate, as the case may be, in effect for that year and an interest charge would be imposed with respect to the resulting tax liability allocated to each such year, o the amount allocated to the current taxable year and any taxable year before we became a PFIC, would be taxable as ordinary income in the current year, and o you would be required to make an annual return on IRS Form 8621 regarding distributions received with respect to the underlying ordinary shares represented by the ADRs and any gain realized on your ADRs. 66 If you make either a timely QEF election or a timely mark-to-market election in respect of“mark-to-market” your ADRs, you would not be subject to the rules described above. If you make a timely QEF election, you would be required to include in your income for each taxable year your pro rata share of our ordinary earnings as ordinary income and your pro rata share of our net capital gain as long-term capital gain, whether or not such amounts are actually distributed to you. You would not be eligible to make a QEF election unless we comply with certain applicable information reporting requirements. Alternatively, if the ADRs are considered "marketable stock" and if you elect to "mark-to-market" your ADRs,Instead, you will generally include in income any excess of the fair market value of the ADRs at the close of each tax year over your adjusted basis in the ADRs. If the fair market value of the ADRs had depreciated below your adjusted basis at the close of the tax year, you may generally deduct the excess of the adjusted basis of the ADRs over its fair market value at that time. However, such deductions generally would be limited to the net mark-to-market gains, if any, that you included in income with respect to such ADRs in prior years. Income recognized and deductions allowed under the mark-to-market provisions, as well as any gain or loss (to the extent of net mark-to-market gains) on the disposition of ADRs with respect to which the mark-to-market election is made, is treated as ordinary income or loss. Loss on a disposition, to the extent in excess of net mark-to-market gains, would be treated as capital loss. Our ADRs should be considered “marketable stock” if they traded at least 15 days during each calendar quarter of the relevant calendar year in more than de minimis quantities.

80

A U.S. Holder of ADRs will not be able to avoid the tax consequences described above by electing to treat us as a qualified electing fund, or QEF, because we do not intend to prepare the information that U.S. Holders would need to make a QEF election.

Backup Withholding and Information Reporting
Payments in respect of ADRs may be subject to information reporting to the U.S. Internal Revenue Service and to U.S. backup withholding tax at a rate equal to the fourth lowest income tax rate applicable to individuals (which, under current law, is 28%). Backup withholding will not apply, however, if you (i) are a corporation or come within certain exempt categories, and demonstrate the fact when so required, or (ii) furnish a correct taxpayer identification number and make any other required certification.
Backup withholding is not an additional tax. Amounts withheld under the backup withholding rules may be credited against a U.S. Holder'sHolder’s U.S. tax liability, and a U.S. Holder may obtain a refund of any excess amounts withheld under the backup withholding rules by filing the appropriate claim for refund with the IRS.
Any U.S. holder who holds 10% or more in vote or value of our ordinary shares will be subject to certain additional U.S. information reporting requirements.
U.S. Gift and Estate Tax
An individual U.S. Holder of ADRs will be subject to U.S. gift and estate taxes with respect to ADRs in the same manner and to the same extent as with respect to other types of personal property.

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKS

We invest our excess cash in interest-bearing accounts and time deposits with government-insured institutions. Certain of our cash equivalents are subject to interest rate risk. Due to the short duration and conservative nature of these instruments, we do not believe that we have a material exposure to interest rate risk. Our major market risk is changes in foreign exchange rates as we have approximately A$26.77.3 million in time deposits held in U.S. dollars as of June 30, 2004.2005. A hypothetical 10% adverse movement in end-of-period exchange rates would reduce the cash balance by approximately A$2.70.7 million.

82

We are currently reviewinghave engaged an external consultant to assist us to manage our cash balances in order to reduce foreign currency exchange risk. We do not currently utilize derivative financial instruments or other financial instruments subject to market risk.

We conduct our activities almost exclusively in Australia. However, we are required to make certain payments in U.S. dollars and other currencies. A hypothetical 10% adverse movement in end-of-period exchange rates would notcould have a material impact on future earnings. our operating results. At 30 June 2005, we had US$12,191 and EUR$314,407 in payables. A hypothetical 10% adverse movement in the US and EUR exchange rates could increase the cost of these payables by A$51,419.

Our management, including our chief executive officer and chief financial officer are responsible for establishing and maintaining our disclosure controls and procedures (within the meaning of Rule 13a-15(e) of the effectivenessSecurities Exchange Act of 1934). We have established and maintain disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed by our company in reports that we file or submit under the designU.S. Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and operationreported within the time periods specified in the Securities and Exchange Commission’s rules and forms and that such information was made known to them by others within the company, as appropriate to allow timely decisions regarding required disclosure.
We evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13(a)-14under the supervision of the Securities Exchange Act of 1934. Based upon that evaluation, our management, including our chief executive officer and chief financial officer as of the end of the period covered by this annual report on Form 20-F. Based upon that evaluation, our chief executive officer and chief financial officer have concluded that, as of such date, our company's disclosure controls and procedures are effectivewere ineffective in timely alerting them to material information relating to us requiredthat we had insufficient accounting personnel that have sufficient knowledge and experience in U.S. GAAP and the Securities and Exchange Commission accounting requirements. The accounting personnel who prepare our financial statements will need to be includedtrained on the application of U.S. GAAP accounting pronouncements and standardized reconciliation templates will need to be improved to assist in the our periodic SEC filings.

Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the objectivesdegree of compliance with the system are met. In addition, the design of any control system is based in part upon certain assumptions about the likelihood of future events. Because of these and other inherent limitations of control systems, there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. policies or procedures may deteriorate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
DELOITTE TOUCHE TOHMATSU

To theThe Board of Directors and StockholdersShareholders of Prana Biotechnology Limited

We have audited the accompanying consolidated statements of financial position of Prana Biotechnology Limited and subsidiaries (a development stage enterprise)company) (the "Company"“Company”) as of June 30, June2005 and 2004 and 2003, and the related consolidated statements of financial performance, cash flows and changes in stockholders' equity and cash flows for each of the three years in the period ended June 30, June 20042005, and for the period from November 11, November 1997 (date of inception) to June 30, June 2004.2005. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includesstatements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, suchthe consolidated financial statements present fairly, in all material respects, the financial position of Prana Biotechnology Limited and subsidiaries as of June 30, June2005 and 2004, and 2003, and the results of itstheir operations and itstheir cash flows for each of the three years in the period ended June 30, June 20042005, and for the period from November 11, November 1997 (date of inception) to June 30, June 2004,2005, in conformity with accounting principles generally accepted in Australia.

Accounting principles generally accepted in Australia differvary in certain significant respects from accounting principles generally accepted in the United States of America. The application of the latter would have affected the determination of net loss for each of the three years in the period ended 30 June 2004 and the determination of total equity as of 30 June 2004 and 2003,Information relating to the extent summarizednature and effect of such differences is presented in Note 25 to the consolidated financial statements. /s/

(a)
Principles of consolidation

The consolidated financial statements are prepared by combining the financial statements of all the entities that comprise the consolidated entity, being the Company (the parent entity) and cash equivalents its controlled entities as defined in Accounting Standard AASB 1024: Consolidated Accounts. The companies comprising the consolidated entity are disclosed above. Consistent accounting policies are employed in the preparation and presentation of the consolidated financial statements.

The consolidated financial statements include the information and results of each controlled entity from the date on which the Company obtains control and until such time as the Company ceases to control such entity.

In preparing the consolidated financial statements, all intercompany balances and transactions, and unrealized profits arising within the consolidated entity are eliminated in full.

(b)
Cash and cash equivalents

For the purposes of the Statement of Cash Flows, cash includes cash on hand and in banks and money market investments readily convertible to cash. (b) Recoverable amount of non-current assets

(c)
Recoverable amount of non-current assets

Each reporting period, the directors assess the recoverable amount of all non-current assets. Where the carrying amount of a non-current asset is greater than its recoverable amount, the asset is revalued down to its recoverable amount. The recoverable amount is estimated based on expected net cash flows discounted to their present values using a market-determined, risk-adjusted discounted rate. (c) Equipment Equipment

(d)
Property and equipment

Property and equipment consists of computer, laboratory equipment, computer equipment, furniture and costs associated withfittings and leasehold improvements attributable to the fitout of ourCompany’s premises at Parkville, Victoria, Australia and is recorded at cost. Depreciation is provided on a straight-line basis over the estimated useful lives of three to 14 years. (d) Intangible assets and research and development expense

(e)
Intangible assets and patents, research and development expense

Until December 1999, costs associated with the acquisition and development of the Company'sconsolidated entity’s core intellectual property were capitalized as intangible assets. After considering an independent valuation of the Company'sconsolidated entity’s core intellectual property at December 1999, the directors revalued the assets upwards by $14,661,942A$14,661,942 to $16,500,000.A$16,500,000. The revaluation was recorded in the asset revaluation reserve in equity. Subsequent to the revaluation, all costs associated with the acquisition and development of core intellectual property are charged to patents, research and development expense.

In accordance with Australian Accounting Standard AASB 1041: Revaluation of Non-Current Assets (“AASB 1041”), on July 1, 2000 the directors deemed the revalued carrying amount of core intellectual property to be cost for financial reporting purposes.

Core intellectual property is being amortisedwas amortized on a straight-line basis over a period of 15 years, being the period in which the future benefits are expected to arise. The directors regularly reviewreviewed the carrying value of core intellectual property to ensure its carrying value doesdid not exceed its recoverable amount. In accordance with

(h)
Revenue recognition

Revenue is recognized to the extent that it is probable that the economic benefits will flow to the entity and the revenue can be reliably measured.

Interest

Interest income is recognized as earned andwhen collectibility is reasonably assured.

Government grants

Government grants are recorded as income when key milestones set within each agreement are achieved and accepted by all parties to the grant. The agreements comprise different phases based on product development. Milestones are based on the phases of each product development, for example Phase 1, Phase 2 and Phase 3. Revenue is not recognized prior to acceptance that the milestones have been achieved, as collectibility is not assured until this point is reached. Once each milestone is reached and approved, the grantor is obligated to pay and there are no further significant obligations as to that part of the milestone. Grant income for achievement of such milestones is agreed between the parties in legally binding contracts. Revenue for each milestone achieved is fixed up front.

Reimbursements

Reimbursements of expenses are recognized as revenue when the reimbursement is received and the related expenses have been incurred.

Corporate partner revenues

Corporate partner revenues are comprised of amounts earned under agreements with Schering A.G. and Neuroscience Victoria Ltd. for certain research and development activities. Revenues are recognized as earned on a straight line basis over the lives of the relevant agreements. The straight line basis is considered appropriate as the agreements do not contain clearly defined milestones. Such agreements are performed on a "best efforts" basis with no guarantee of either technological or commercial success. (h) Income tax

(i)
Income tax

Tax-effect accounting is applied using the liability method whereby income tax is regarded as an expense and is calculated on the accounting profit after allowing for permanent differences. To the extent timing differences occur between the time items are recognized in the financial statements and when items are taken into account in determining taxable income, the net related taxation benefit or liability, calculated at current rates, is disclosed as a future income tax benefit or a provision for deferred income tax. The net future income tax benefit relating to tax losses is not carried forward as an asset unless the benefit is virtually certain of being realized. The future income tax benefit relating to timing differences is not carried forward as an asset unless its realization is assured beyond reasonable doubt.

Where assets are revalued, no provision for potential capital gains tax has been made. F-9 PRANA BIOTECHNOLOGY LIMITED (A Development Stage Enterprise) 1 BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES continued (i) Employee entitlements

Employee entitlements

Provision is made for employee entitlement benefits accumulated as a result of employees rendering services up to the reporting date. These benefits include wages and salaries, annual leave and long service leave.

Employee entitlements expenses and revenues arising in respect of the following categories: o

·Wages and salaries, non-monetary benefits, annual leave, long service leave, sick leave and other leave entitlements; and o Other types of employee entitlements; and

(k)
Loss per share

Basic loss per share is determined by dividing the loss from ordinary activities after income tax by the weighted average number of ordinary shares outstanding during the period. The computation of diluted loss per share is similar to basic loss per share, except that it assumes the potentially dilutive securities, such as share options and warrants, were converted to shares as of the beginning of the period. For all periods presented, diluted loss per share is equivalent to basic loss per share as the potentially dilutive securities are excluded from the computation of diluted loss per share because the effect is anti-dilutive. See Note 18. (k) Financial instruments issued by the Company

Financial instruments issued by the consolidated entity

Debt and equity instruments - ---------------------------

Debt and equity instruments are classified as either liabilities or as equity in accordance with the substance of the contractual arrangement.

Transaction costs on the issue of equity instruments - ----------------------------------------------------

Transaction costs arising on the issue of equity instruments are recognized directly in equity as a reduction of the proceeds of the equity instruments to which the costs relate. Transaction costs are the costs that are incurred directly in connection with the issue of those equity instruments and which would not have been incurred had those instruments not been issued.

(r)
Leased assets

A finance lease is one which effectively transfers from the lessor to the lessee substantially all the risks and benefits incidental to ownership of the leased property. Leased assets classified as finance leases are recognized as assets. The amount initially brought to account is the present value of minimum lease payments. Finance leased assets are amortized on a straight line basis over the estimated useful life of the asset. Finance lease payments are allocated between interest expense and reduction of lease liability over the term of the lease. The interest expense is determined by applying the interest rate implicit in the lease to the outstanding lease liability at the beginning of each lease payment period.

Operating lease payments are recognized as an expense on a basis which reflects the pattern in which economic benefits from the leased asset are consumed.

(s)
Provisions

Provisions are recognized when the consolidated entity has a present obligation, the future sacrifice of economic benefits is probable, and the amount of the provision can be measured reliably.

When some or all of the economic benefits required to settle a provision are expected to be recovered from a third party, the receivable is recognized as an asset if it is probable that recovery will be received and the amount of the receivable can be measured reliably.

The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at reporting date, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows.

(t)
Adoption of Australian Equivalents to International Financial Reporting Standards (Unaudited)

The consolidated entity will be required to prepare financial statements that comply with Australian equivalents to International Financial Reporting Standards (“A-IFRS”) for reporting periods beginning on or after January 1, 2005. Accordingly, the consolidated entity’s first half-year report prepared under A-IFRS will be for the half-year reporting period ending December 31, 2005, and its first annual financial report prepared under A-IFRS will be for the year ending June 30, 2006.

The consolidated entity has completed an A-IFRS impact study, including the formulation of the A-IFRS accounting polices that are intended to be adopted from July 1, 2005. The likely impact of the accounting policy changes on the results and financial position of the consolidated entity has been determined.

The following Pro Forma Consolidated Statements of Financial Performance and Financial Position outline the impact on the current year result and financial position of the consolidated entity had the financial statements been prepared using A-IFRS, based on the directors’ accounting policy decisions current at the date of this financial report. Users of the financial reports should note that further developments in A-IFRS (for example, the release of further pronouncements by the Australian Accounting Standards Board and the Urgent Issues Group), if any, may result in changes to the accounting policy decisions made by the directors to date, and, consequently, the likely impacts outlined in the following pro forma financial statements.

The directors may, at any time until the completion of the consolidated entity’s first A-IFRS compliant financial report, elect to revisit and, where considered necessary, revise the accounting policies applied in preparing the pro forma financial statements.

(t) Adoption of accounting data for future comparative purposes at the beginning of the next financial year. Australian Equivalents to International Financial Reporting Standards (Unaudited) (continued)

The Company's management is assessing the significance of these changes and preparing for their implementation. The Company will seek to keep stakeholders informed asfollowing explanatory notes relate to the impactunaudited pro forma consolidated financial statements above and describe the differences between the accounting polices under A-IFRS and the current treatment of these new standards as they are finalized. The directors are ofthose items under Australian Generally Accepted Accounting Principles (“A-GAAP”).

A. Share-based Payments
Under A-GAAP, the opinion that the key differences in the Company's accounting policies which will arise from the adoption of IFRS are: Share-based Payments - The Company currently has the policy of expensing shares issued in lieu of paymentconsolidated entity does not recognize an expense for goodsshare-based compensation granted to employees or services by valuing them at their cost under the contract; however, under IFRS the Company will be required to expense the cost of such shares based on the fair value (i.e., market price) of the shares. Additionally, under IFRS the Company will be required to expense the cost of share options based ondirectors. Under A-IFRS, the fair value of theshare options issued to employees and directors is determined at the grant date. Currently,date and expensed over the Company doesexpected vesting period of the options. As permitted under A-IFRS first time adoption, the consolidated entity will not retrospectively recognize compensation cost for option grants. Intellectual Property - The Company currently has intangible assets which wereshare-based payments that have vested before January 1, 2005.

For the year ended June 30, 2005, under A-IFRS, contributed equity will increase by A$1,704,734 and an additional employee benefits expense of the same amount will be recognized in profit and loss in relation to the options issued during the year.

B. Intangible Assets
Under A-GAAP, the consolidated entity revalued upward by $14,661,942the core intellectual property to fair value in December 1999. ForUnder A-IFRS, the revaluation increment to continue to be recognized under IFRSis permissible only if there must beis an active market in whichfor the intangible can be traded. Theasset. As a consequence, upon transition to A-IFRS at July 1, 2004, intangible assets must also bewill decrease by A$10,208,582 with an associated decrease in the asset revaluation reserve of A$14,661,942 and accumulated losses of A$4,453,360 at that date.

Under A-IFRS, internally generated intangible assets from expenditure on research activities are not recognizable. As a consequence, upon transition to A-IFRS at July 1, 2004, intangible assets will decrease by A$410,321 with a corresponding increase in accumulated deficit at that date.

As a result of contractual or legal rights or separable from the business. It is anticipated thatabove transition adjustments, the carrying value of the intangible assets at 1 July 2004 was A$869,440.

The impact of the above transition adjustment to A-IFRS for the year ended June 30, 2005 is that the amortization expense will not be able to be separately identified and that there will be no active market in which to value the intangible assets. As a result, the revaluation increment may be derecognized from the Statement of Financial Positiondecrease by A$1,016,804 and the amortization previously taken up may be reversed. F-11 impairment of intangible assets will decrease by A$9,602,099. In addition, the asset revaluation reserve as at June 30, 2005 will decrease by A$14,661,942.

C. Financial Instruments
The directors have elected not to apply the first-time adoption exemption available to Prana to defer the date of transition of AASB 132: Financial Instruments: Disclosure and Presentation and AASB 139: Financial Instruments: Recognition and Measurement' to July 1,2005. This has nil effect on the consolidated financial statements.

Options issued to consultants On 6 January 2000,for services rendered

As disclosed in Note 11(c), the Company issued 400,000600,000, 1,444,500 and 405,000 share options as an incentive forto outside consultants.consultants during the years ended June 30, 2005, 2004 and 2003, respectively. Under A-GAAP, nothe Company recognized compensation expense based on the directors’ valuation of the options issued during the year ended June 30, 2005. No compensation cost has been recognisedwas recognized in respect of the share options issued by the Company.Company during the years ended June 30, 2004 and 2003 under A-GAAP. Under US GAAP, the options issued to the outside consultants are accounted for under Statements of Financial Accounting Standards ("SFAS"(“SFAS”) No. 123: Accounting for Stock-BasedStock Based Compensation ("(“SFAS 123"123”) and Emerging Issues Task Force Issue No. 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"96-18”). Under SFAS 123 and EITF 96-18, compensation cost is calculated based on the fair value of options on the date at which the counterparty's performance is complete. The fair value of the options was estimated on the date of grant using the Black-Scholes model with the following weighted average assumptions: o risk-free interest rate of 5.6%; o no dividends; o expected volatility of 21%; and o expected life of four years. The compensation cost is charged to earnings over the period from the date of grant (6 January 2000) to the date the consultants' performance was complete (28 March 2002) and adjusted at each statement of financial position date (up to 28 March 2002) for changes in the fair value of the options. Options issued to consultants for services rendered The Company issued 1,444,500, 405,000 and 400,000 share options to outside consultants during the years ended 30 June 2004, 2003 and 2002, respectively. Certain options were issued under the Employee and Consultants Option Plan 2000 as a reward for services rendered and the remaining options were issued in consideration for services rendered to the Company. Under A-GAAP, no compensation cost has been recognised in respect of the share options issued by the Company. Under US GAAP, the options issued to the outside consultants are accounted for under SFAS 123 and 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 5.50% for 2004, 4.47% for 2003 and 5.48% for 2002; o no dividends; o expected volatility of 82% for 2004, 48% for 2003 and 25% for 2002; and o expected life of two years for 2004, two years for 2003 and three years for 2002.
·risk-free interest rate of 4.9% for 2005, 5.5% for 2004 and 4.5% for 2003;
·no dividends;
·expected volatility of 62% for 2005, 82% for 2004 and 48% for 2003; and
·expected life of two years for 2005, 2004, and 2003.

The compensation cost is charged to operations ratably over the vesting period. The resulting difference between the A-GAAP compensation expense (if any) and the US GAAP compensation expense is recognized in the reconciliation.

Options issued to directors and employees for services rendered

As disclosed in Note 11(c), the Company issued 2,480,000, 264,667 and 158,274 share options to employees under the Employeedirectors and Consultants Option Plan 2000 as a reward for services rendered to the Companyemployees during the years ended June 30, June2005, 2004 and 2003, respectively. Under A-GAAP, no compensation cost has been recognisedrecognized 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 directors and employees in accordance with Accounting Principles Board (“APB”) Opinion No. 25: Accounting for Stock Issued to Employees and related interpretations ("(“APB 25"25”). Under APB 25, compensation cost is recognisedrecognized to the extent that the quoted market price of the stock exceeds the exercise price of the options at the grantmeasurement date, and is charged to earnings ratably over the vesting period. F-31 For options that vest upon the achievement of a target stock price, compensation expense is recognized when the target is achieved.

Had compensation cost related to the issuance of options to directors and employees been recorded at fair value on the date of grant in accordance with SFAS 123, the consolidated entity’s net loss and loss per share amounts (calculated in accordance with US GAAP) would have been reduced to the pro forma amounts indicated below:

Such costs are amortisedwere amortized on a straight-line basis over the estimated useful liveslife of 15 years. In December 1999, the directors revalued the intangible assets upwards by $14,661,942A$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

Under US GAAP, purposes, the Company capitalises costs associated with the acquisition of patents and other core intellectual property are capitalised while costs associated with the development of core intellectual property are expensed as incurred. Upward revaluations of intangible assets are not allowed (except in connection with a purchase business combination). Accordingly, the amortization expense attributable to the costs capitalized under A-GAAP but expensed under US GAAP as well as the amortization expense attributable to the upward asset revaluation is reversed in the accompanying reconciliation.

As a result of the cancellation of a clinical study for the compound PBT-1 in April 2005 due to toxicity issues, the consolidated entity reviewed the carrying value of the core intellectual property and resolved to impair the value to A$nil as of June 30, 2005 based on estimated future discounted cash flows.

Such costs are amortisedapplications deemed to be recoverable from the future development of products were capitalised and amortized on a straight-line basis over the estimated useful liveslife of 15 years. Such capitalised costs are tested for recoverability whenever events or circumstances indicate that the carrying amount of the costs may not be recoverable. All other costs associated with patents and other core intellectual property arewere expensed as incurred. Upward revaluations of intangible assets are not allowed underEffective January 1, 2005, the Company changed its US GAAP (exceptaccounting policy and expenses all patent costs as incurred.

The weighted average grant date fair value of the options issued to directors under the 2004 Employees, Directors and Consultants Share and Option Plan during the year ended June 30, 2005 and options issued to employees under the Employee and Consultants Option Plan 2000 during the years ended June 30, 2004 and 2003 is A$0.44, A$0.44 and A$0.43, respectively. The fair value was estimated at the date of the grant using the Black-Scholes option pricing model for options without market conditions and the Barrier option pricing model was used for options with market conditions, with the following weighted average assumptions:

·risk-free interest rate of 5.2% for 2005, 4.9% for 2004 and 4.3% for 2003;
·no dividends;
·expected volatility of 65.7% for 2005, 74.3% for 2004 and 82.0% for 2003; and
·expected life of five years for 2005 and two years for 2004 and 2003.

The following table summarizes the activity of share options issued to directors under the 2004 ADS Option Plan during the year ended June 30, 2005. Each option is exercisable for one ADR which equals ten shares. The 2004 ADS Option Plan was adopted on November 17, 2004 and therefore no options were issued under the plan in prior years.

(c)All 1,212,000 options outstanding as of June 30, 2005, have an exercise price of A$0.50 with an average remaining contractual life of two years.

The weighted average grant date fair value of options issued to consultants during the years ended June 30, 2005, 2004 and 2003 is A$0.27, A$0.30 and A$0.19, respectively. Refer to Note 25(a), Options issued to consultants for services rendered for the assumptions used to estimate the grant date fair value.

As previously disclosed, the Company issued 55,000 share options to underwriters on March 1, 2003 which were immediately exercised on the same day. Because the options were exercisable only on the date of grant, the Company estimated the grant date fair value of A$0.48 based on the intrinsic value of the options.

Refer to Notes 11(b) and 11(d) for information regarding shares and warrants granted to consultants and directors during the years ended June 30, 2005, 2004 and 2003

Income tax

The consolidated entity has adopted SFAS No. 109: Accounting for Income Taxes (“SFAS 109”) for US GAAP purposes. SFAS 109 requires a “liability approach” to accounting for income taxes, which as it applies to the consolidated entity, is very similar to that adopted under A-GAAP.

Under A-GAAP, the deferred tax asset in respect of income tax losses carried forward disclosed in Note 4 is not recognized unless the benefit is virtually certain of realisation. Under US GAAP, the benefit is not recognized unless realisation is more likely than not.

25RECONCILIATION TO US GAAP (continued)

Recently issued but not yet adopted accounting pronouncements

In December 2004, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 123 (revised 2004): Share-Based Payments (“SFAS 123R”). This statement eliminates the option to apply the intrinsic value measurement provisions of APB 25 to stock compensation awards issued to directors and employees. Rather, SFAS 123R requires companies to measure the cost of director and employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost will be recognized over the period during which the director or employee is required to provide services in exchange for the award -- the requisite service period (usually the vesting period). SFAS 123R applies to all awards granted after the required effective date (July 1, 2005 for Prana) and to awards modified, repurchased, or cancelled after that date. 

As permitted by SFAS 123, the consolidated entity currently accounts for share-based payments to directors and employees using APB 25, the intrinsic value method. Accordingly, the adoption of the SFAS 123R fair value method may have a significant impact on the consolidated entity’s results of operations, although it will have no impact on its overall financial position. The full impact of the adoption of SFAS 123R cannot be predicted at this time, as it depends on levels of share-based payments for future grants. However, had the consolidated entity adopted SFAS 123R in prior periods, the impact of that standard would have approximated the impact of SFAS 123, as disclosed in Note 25(a), Share-based compensation -Options issued to directors and employees for services rendered.

In December 2004, the FASB issued SFAS No. 153: Exchanges of Nonmonetary Assets - an amendment of APB Opinion No. 29 (“SFAS 153”), which amends APB Opinion No. 29: Accounting for Nonmonetary Transactions to eliminate the exception for nonmonetary exchanges of similar productive assets and replaces it with a general exception for exchanges of nonmonetary assets that do not have commercial substance. SFAS 153 is effective for nonmonetary assets exchanges occurring in fiscal periods beginning after June 15, 2005 (fiscal 2006 for Prana).  At this time, management reasonably believes that the adoption of SFAS 153 will not have a material effect on the consolidated entity’s financial position or results of operations.

In May 2005, the FASB issued SFAS No. 154: Accounting Changes and Error Corrections (“ SFAS 154”), a replacement of APB Opinion No. 20: Accounting Changes and SFAS No. 3: Reporting Accounting Changes in Interim Financial Statements, effective for fiscal years beginning after December 15, 2005 (fiscal 2007 for Prana). SFAS 154 changes the requirements for the accounting for and reporting of a voluntary change in accounting principle as well as the changes required by an accounting pronouncement which does not include specific transition provisions. At this time management reasonably believes that the adoption of SFAS 154 will not have a material effect on the consolidated entity’s financial position or results of operations.
