INTRODUCTION

Prana Biotechnology Limited was 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 causes of degeneration of the brain and the eye as the aging process progresses, initially focusing on Alzheimer’s disease. Other potential applications for our therapies include age-related cataracts, Huntington disease, Creutzfeldt-Jakob disease (the human variant of Mad Cow disease), Motor Neuron disease and Parkinson’s disease. The principal listing of our ordinary shares and listed options to purchase our ordinary shares is on the Australian Stock Exchange. Since September 5, 2002, our American Depository Receipts, or ADRs, have traded on the NASDAQ Capital Market under the symbol “PRAN.” The Bank of New York, acting as depositary, issues our ADRs, each of which evidences an American Depositary Share, which in turn represents ten of our ordinary shares. 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.

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 products, including our current lead product candidate, PBT-2, to market or generate revenues from their commercial application. Our current or any future product candidates, if successfully developed, may 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-2 or develop other pharmaceutical products.
We may not be able to develop our current or any future pharmaceutical product candidates adequately to attract a suitable collaborative partner. The projects initially specified in connection with any such collaboration and any associated funding, may change or discontinue with the changing interests of either the collaborator or us, and any such change may change the budget for the projects under the collaboration. Additionally, our research may not lead to the discovery of additional product candidates, and any of our current and future product candidates may 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.The products we develop may 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 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 products.
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, regardless of its development stage or the investment of time and funds in its development, will continue to be funded or developed.
4

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.after March 2007. 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;
8

 
 ·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 thatand we willmay not 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 ableOur failure to commercialize PBT-2 or any future 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.
5

We may not be able to undertake further clinical trials of PBT-2 and any future product candidate, including one that may emerge from our vaccine program, or to demonstrate the safety and efficacy or superiority of any of these product candidates over existing therapies or other therapies under development, or enter into any collaborative arrangement to commercialize our current or future 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 couldraise additional capital before March 2007 would have a material adverse effect on our company’s ability to continue as a going concern and to achieve its business objectives. Our auditors have included a going concern uncertainty paragraph in their report. The accompanying financial condition and resultsstatements do not include any adjustments relating to the recoverability of operations.the carrying amount of recorded assets or the amount of liabilities that might result should we be unable to continue as a going concern. 
 
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:
 
 ·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.

9

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, larger or largermore complex 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.
 
There is a substantial risk that we may not be able to complete the development of PBT-2 or develop other pharmaceutical products.
We may not be able to progress with the development of our current or any future pharmaceutical product candidates to a stage that will attract a suitable collaborative partner for the development of any current or future pharmaceutical product candidates. The projects initially specified in connection with any such collaboration and any associated funding may change or be discontinued as a result of changing interests of either the collaborator or us, and any such change may change the budget for the projects under the collaboration. Additionally, our research may not lead to the discovery of additional product candidates, and any of our current and future product candidates may 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.The products we develop may 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 payers. We cannot predict if or when 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 products.
We may need to prioritize the allocation of development resources and/or funds towards what we believe to be our most promising product or 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, regardless of its development stage or the investment of time and funds in its development, will continue to be funded or developed.
610


We will not be able to commercialize our PBT-2 therapeutic compound for Alzheimer’s disease or any future 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 PBT-2 product candidate is 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.
We may not be able to undertake further clinical trials of our PBT-2 compound as a therapeutic for Alzheimer’s disease and any future product candidate (including one that may emerge from our vaccine program), or to demonstrate the safety and efficacy or superiority of any of these product candidates over existing therapies or other therapies under development, or enter into any collaborative arrangement to commercialize our current or future product candidates on terms acceptable to us, or at all. For example, in April 2005, we ceased clinical trials of our PBT-1 compound as a treatment for Alzheimer’s disease. 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 have limited manufacturing experience with our product candidates. Delays in manufacturing sufficient quantities of such materials to the required standards for pre-clinical and clinical trials may negatively impact our business and operations.
 
We may not be able to manufacture sufficient quantities of PBT-2 or any futureother development or 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.
 
We may be required to enter into contracting arrangements with third parties to manufacture PBT-2 and any futureother development or product candidates for large-scale, preclinical and/or clinical trials. We may 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 may 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 may 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 expect 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.develop or may develop in the future. 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 material adverse effect on the priority of the development of our product candidates, our business, financial condition and results of operations.
 
11


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.Limited. We intend to continue these relationshipsthis relationship and this approach with further compounds if itthe relationship 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-2. We reported a net losslosses of A$25,008,597, A$9,885,61411,719,309 and A$4,584,83816,094,428 during the fiscal years ended June 30, 2005, 2004,2006 and 2003,2005, respectively. As of June 30, 2005,2006, our accumulated deficit was A$50,473,473.49,235,574. We may notnever be able to achieve or maintain profitability.

Our success depends upon our ability to protect our intellectual property and our proprietary technology.
 
Any future success will depend in large part on whether we can:
 
 ·obtain and maintain patents to protect our own products;products and technologies;

 ·obtain licenses to the patented technologies of third parties;

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

 ·protect our trade secrets, know-how and know-how.other confidential information.

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. Any of the pending or future patent applications filed by us or on our behalf may not be approved, or we may not develop additional proprietary products or processes that are patentable or that we will be able to license any other patentable products or processes.
12

 
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. Licenses required under patents held by third parties may 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, export, 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. We may have to defend the validity of our patents in order to protect or enforce our rights against a 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 and Heathcare ProductsHealthcare products Regulatory Agency, or MHRA, in the United Kingdom, the Medical Products Agency, or MPA, in Sweden and the European Medicines Evaluation Authority,Agency, 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 MHRA 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 may 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.
 
13

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 may 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 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, MHRA, MPA, 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 our PBT-2 product 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.
 
Our current or future products may not achieve market acceptance even if they are approved by the TGA, FDA or any other regulatory authority. The degree of market acceptance of such products will depend on a number of factors, including:
 
 ·the receipt and timing of regulatory approvals for the uses that we are studying;

14

 ·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. Qualified personnel may not be available in adequate numbers or at a reasonable cost. Further, additional financing may not be available on acceptable terms, or at all, and our sales staff may 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 may not be able to enter into marketing arrangements with any marketing partner or if such arrangements are established, our marketing partners may 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 future 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 payorspayers 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.
 
15

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 historically obtained no fault compensation insurance for the PBT-1 clinical trial and extension study and the PBT-2our clinical trials and intend to obtain similar coverage for future clinical trials. Such coverage may 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. We may not be able to obtain product liability insurance in the event of the commercialization of a product or such 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.
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.
11

Risks Relating to Our 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. During the last two fiscal years, the market price for our ordinary shares on the Australian Stock Exchange has ranged from as low as A$0.13 to a high of A$1.180.70 and the market price of our American Depositary Shares on the NASDAQ Capital Market has ranged from as low as US$0.98 to a high of US$10.50.5.05. The market price for our securities 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:
 
 ·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;

16

 ·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.
 
As a result of recentchanges to the laws, regulations and standards relating to accounting, corporate governance scandals and the legislative and litigation environment resulting from those scandals,public disclosure, the costs of being a public company in general have increased.increased in recent years. 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 implementationEffective as of our fiscal year ending June 30, 2008, we will be required to implement Section 404 of the Sarbanes-Oxley Act of 2002, which governs internal controls and procedures for financial reporting,reporting. The compliance with respect to the requirement to provide an auditor’s attestation report on internal control over financial may be subject to additional relief granted by the Securities and Exchange Commission. We expect that we will require usneed to expend significant management time and financial resources to comply with the applicable requirements. This and other enacted and 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.requirements; the failure to adequately train our accounting staff could result in a material misstatement to our annual or interim financial statements.
 
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 CommissionSEC 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-GAAPA-IFRS 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.
 
17

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 ADRs who are U.S. residents face income tax risks. There is a substantial risk that we are a passive foreign investment company, commonly referred to as PFIC. Our treatment as a PFIC could result in a reduction in the after-tax return to the holders of our ADRs and would likely cause a reduction in the value of such 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, cash is considered to be an asset, which produces passive income. As a result of our substantial cash position and the decline in the value of our stock, we believe that we became a PFIC in 2004during the taxable year ended June 30, 2005, and will once again qualify as a PFIC during the taxable year ended June 30, 2006, under a literal application of the asset test described above, which looks solely to the market value.  If we are classified as a PFIC for U.S. federal income tax purposes, highly complex rules would apply to U.S. holdersowning ADRs.  Accordingly, you are urged to consult your tax advisors regarding the application of such rules. United States residents should carefully read “Item 10E. Additional Information - Taxation, United States Federal Income Tax Consequences” for a more complete discussion of the U.S. federal income tax risks related to owning and disposing of our 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.

13

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. Most 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.

18

As a foreign private issuer whose shares are listed on the NASDAQ Capital Market, we may follow certain home country corporate governance practices instead of certain NASDAQ requirements.
As a foreign private issuer whose shares are listed on the NASDAQ Capital Market, we are permitted to follow certain home country corporate governance practices instead of certain requirements of NASDAQ Marketplace Rules. A foreign private issuer that elects to follow a home country practice instead of such requirements, must submit in advance to NASDAQ a written statement from an independent counsel in such issuer’s home country certifying that the issuer’s practices are not prohibited by the home country’s laws. In addition, a foreign private issuer must disclose in its annual reports filed with the Securities and Exchange Commission each such requirement that it does not follow and describe the home country practice followed by the issuer instead of any such requirement. As an Australian company listed on the NASDAQ Capital Market, we may follow home country practice with regard to, among other things, composition of the Board of Directors, director nomination procedures, compensation of officers, and quorum at shareholders meetings.

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’s disease. Other potential applications for our therapies include age-related cataracts, Huntington’s disease and Parkinson’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 disease targets. Initially we focused on clinical trials of our PBT-1 compound as a therapeutic for the treatment of Alzheimer’s disease. We commenceddisease and in early August 2003, our planned phase II human clinical trialPBT-2 compound was announced as a new lead metal protein attenuating compound, or MPAC, molecule 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. disease.
On April 11, 2005, we announced that we would not proceed with the PLACQUEscheduled Phase II/III study of PBT-1 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. On June 30, 2005, our Board of Directors determined that the core intellectual property relating to PBT-1 had been impaired and the carrying value was written-off. As a result of these events, we proceeded to conduct a strategic review of our pending strategic development programs.

On June 16, 2005, we announced that we had completed a review of our strategic development programs and we reaffirmed our commitment to PBT-2, our lead candidate for the potential treatment of Alzheimer's disease, PBT-2. disease. 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.a mutagenic potential. 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 builtdesign, was designed “from the ground up” to fulfill very specific criteria. It was designed so that it willto be orally bioavailable and to cross the blood brain barrier. PBT-2 was selected from over 300several hundred 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'sAlzheimer’s disease. FormalInitial preclinical toxicology testing for PBT-2 has beenwas 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 (absorption, distribution, metabolism, and excretion) 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.development candidate. Concurrent findings in a pre-clinical mouse model indicate that PBT-2 passes into the brain of mice more extensively than its predecessor, PBT-1. We haveIn early 2006, we also successfully completed three out of four stages of oura second Phase I clinical trial, a multi-dose escalation safety clinical trial of PBT-2 in 32 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.
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, establishedvolunteers (45 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 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. These projects were designed to investigate the possibility of the use of MPACs and similar compounds 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, 2005.75 years).

We have also identified
On May 5, 2006 we announced that we received an expert report in respect of the Phase I trials for PBT-2. The expert report was prepared by Dr. Craig Ritchie, psychiatrist and filedDirector of Mental Health Clinical Trials at University College London and a clinical advisor to our company. Dr. Ritchie reported that the two Phase I studies indicate that PBT-2 is generally well tolerated at doses to 800mg, that in both studies there were no differences of clinical significance in overall rates of adverse effects between PBT-2 and the placebo groups and there appears to be no relationship between dose and rate of adverse effects. Of the adverse effects that were seen, the vast majority of these were thought to be unrelated to PBT-2 treatment and of the few that were possibly related, they appeared mild and self limiting. Dr. Craig Ritchie concluded that the Phase I results provide the confidence needed to move forward to formal Phase II testing in people with Alzheimer’s disease. The data from the two studies indicate that after oral administration, in healthy human volunteers, PBT-2 is rapidly absorbed (Tmax < 3hrs), achieves good blood levels (in the micromolar range), is primarily metabolized to PBT-2-glucuronide and is renally cleared. PBT-2 exposure increases with increasing single doses, with relatively little accumulation on repeat dosing. Dosing in the clinical trials did not exceed 800mg. once daily for seven days. The terminal elimination rate (apparent clearance) appeared relatively consistent across all doses tested. PBT-2 appears well tolerated in both male and females and there appears little, if any, age difference in the tolerability or pharmacokinetics (absorption, distribution, metabolism, and excretion) of PBT-2. The most common adverse effects noted were headache, gastrointestinal disturbance and somnolence. Dosing did not appear to reach the maximum tolerated dose for healthy volunteers.
21

On May 11, 2006, we announced our plans to move forward with a Phase IIa clinical trial for PBT-2 in patients with Alzheimer’s disease. The study, to be conducted in several sites in Sweden, will evaluate the safety and tolerability of PBT-2, as well as measures of the drug’s mechanism of action and indicators of potential efficacy in Alzheimer’s disease. The Phase IIa study is a randomized, double-blind, placebo-controlled design, in which Alzheimer’s disease patients will receive three months of either one of two oral doses of PBT-2, or placebo. In addition to examining safety and tolerability, the study will investigate the ability of PBT-2 to affect multiple cerebrospinal fluid, or CSF biomarkers, and blood biomarkers of Alzheimer’s disease during the treatment period. Outcomes will include measures of CSF a-beta and tau levels as well as neurocognitive and behavioral changes. The study is expected to commence enrollment in the fourth quarter of 2006, subject to final regulatory approval, and assuming such start date, results are expected to be reported by the end of 2007.
Our company is the exclusive licensee of an international patent application in the name of the General Hospital Corporation 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 followinghaving achieved the completion of project milestones stipulated in the grant,scientific milestone demonstrating that a mouse could generate antibodies that preferentially recognize dimerized βAmyloid.

The research will assess the ability of the immune system to selectively produce specific antibodies which target the “toxic linked” forms of beta amyloid associated with the pathology of Alzheimer’s disease, as an effective treatment for the disease.research.
 
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, 20052006 our capital expenditures have totaled A$272,757. 240,453. We have not incurred any material capital expenditures since July 1, 2005.2006.
 
B. Business OverviewBUSINESS 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 pathology of the disease is based on the inter-relationship between metals and proteins. 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’s disease and Huntington’s disease. These findings continue to strengthen the “theory of metal related 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 neurodegenerative diseases which comprise our disease targets.
17

The protein believed to be involved in the toxicity associated with Alzheimer's disease is βAmyloid.beta amyloid. Very little was known about βAmyloidbeta-amyloid 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’s disease research.
 
22

In 1987, Professors. Masters and Beyreuther and Professor Rudolph Tanzi of Harvard Medical School discovered how βAmyloidbeta-amyloid was produced and in 1994, Professor Ashley Bush of Harvard Medical School discovered that the interaction between metals and βAmyloidbeta-amyloid is associated with the toxicity seen in Alzheimer’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:
 
 ·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,demonstrated that clioquinol, codenamed PBT-1, which was used in our Phase II human clinical trials. Our research program also aims to find further and potentially more effective preferred compoundshad potential efficacy for the treatment of Alzheimer’s disease as well as for our other major disease indications (such as Parkinson’s disease and Huntington’s disease). Thesedisease. Our research efforts have leadled to the development of a 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 400300 MPAC molecules in total (approximately 300200 of which are of the same chemical class as PBT-1 and the remaining MPACs are of other chemical classes). Our research program aims to find further and potentially more effective preferred compounds for the treatment of Alzheimer’s disease as well as for our other major disease indications (such as Parkinson’s disease and Huntington’s disease).
 
Platform Technology and Research Programs
 
We regard our intellectual property as a “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. To date, the majority of our research efforts have been directed at research into potential therapeutics for the treatment of Alzheimer’s disease. Recent publishedPublished 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:
 
18

 ·Age-related cataracts;
 
 ·Parkinson’s disease;
 
23

 ·Huntington’s disease; and
 
 ·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-amyloidbeta-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 b-amyloid. PBT-2 has completed the initial formal preclinical toxicology testing required to support initial human trials and in March 2005, we commencedbeta-amyloid. For 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 completiondescription 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 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 researchhistory and development projects underof our licensing and research collaboration with Schering A.G. and Neurosciences Victoria Ltd. concentratedlead PBT-2 compound as a therapeutic for the treatment of Alzheimer’s disease see Item 4A. “Information on the developmentCompany - History and 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.Company.”
 
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 indicateindicates 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 150between 11 to 14 people per 100,000 or 2.5% of personsand the incidence increases to 44 people per 100,000 for people aged over the age of 85.50. 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 frommodel of the disease, which concluded with positive results. In addition, groups unrelated to us have demonstratedpublished data that demonstrates the usefulness of clioquinol in treating the symptoms of Parkinson’s disease generated in preclinical modelsthe alternative MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) mouse model of the disease. TheseBased on these positive results although yetwith clioquinol in such two mouse models , we plan to be repeated, provide further supportinvestigate the efficacy of other selected MPACs in these models to our position that MPACs (clioquinol and others) may provide a usefulscreen for possible MPAC candidates as treatment incandidates for Parkinson’s disease patients.disease.
24

 
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 recentlyhave 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 researchers based at the Veterans Affairs Medical Center and the Department of Neurology, University of California, San Francisco, under a collaborative research agreement.
 
Clinical Trials
 
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 clioquinol, 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, known 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 study, during which they received treatment with PBT-1 for an additional 48 weeks.
20

The trial was performed to contemporary “best practice” clinical trial standards. We contracted Kendle Pty Ltd. to manage the clinical trials, ensuring compliance to the required international standards of Good Clinical Practice as set out by the International Conference on Harmonization. These protocols provide strict guidelines for the performance of clinical trials in an ethical and scientifically acceptable 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:
·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.
·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.
·The trial protocol required close monitoring of all patients by a safety committee of clinical experts. This committee independently monitored all 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:
·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.
21

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 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’s disease. The details of the trial findings are available on our website (www.pranabio.com), however the information in our website is not 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 and was selected by us as a development candidate. At such time, we initiated the initial formal preclinical toxicology testing required to support initial human trials.trials, which was successfully completed in early 2005. 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. SeeIn early 2006, we also successfully completed a second Phase I multi-dose escalation safety clinical trial of PBT-2. On May 5, 2006, we announced that we received an expert report in respect of the Phase I trials for PBT-2. The expert report was prepared by Dr. Craig Ritchie, psychiatrist and Director of Mental Health Clinical Trials at University College London and a clinical advisor to our company. Dr. Craig Ritchie concluded that the Phase I results provide the confidence needed to move forward to formal Phase II testing in people with Alzheimer’s disease. On May 11, 2006, we announced our plans to move forward with a Phase IIa clinical trial for PBT-2 in patients with Alzheimer’s disease. The study is expected to commence enrollment in the fourth quarter of 2006, subject to final regulatory approval, and assuming such start date, results are expected to be reported by the end of 2007. For additional details regarding our clinical trials see Item 4.A. "Information“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 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 βAmyloidbeta-amyloid theory of Alzheimer'sAlzheimer’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’s disease the βAmyloid Protein) andbeta-amyloid protein) to allow the design of new chemical entities with the propensity to influence targeted substances and processes. In the case of MPACs, the targeted substances (proteins)believed important are proteins and metals and the process of specific interest is believed to be metal-mediated oxyradical formation which leads to neurodegenerative changes.
 
25

Our medicinal chemistry program is based at laboratories that we lease 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 targetcertain aggregating proteins such as βAmyloid.beta-amyloid. Compounds continue to be designed, synthesized and undergo the required early phase preclinical screening 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 and we believe that rational drug design will provide new and specifically designed drugs which will display efficacy in disaggregating aggregation-prone proteins such as βAmyloid,beta-amyloid, 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 by our medicinal chemistry group to undertake preliminary in vivo pharmacology and kinetic studies of the new compounds demonstrating activity in the in vitro screens was establishedscreens. We perform in vivo modeling for our lead compound candidates for Alzheimer’s disease with transgenic mice expressing a similar phenotype to human Alzheimer’s disease. Similarly, a transgenic mouse carrying a mutated Huntingtin gene is used to model Huntington’s disease and mice treated with neuronal toxins to produce the Parkinson’s phenotype are used to model Parkinson’s disease. Based on the results of these studies, lead compounds are selected by our medicalmedicinal chemistry group. The Alzheimer’s disease transgenic mouse model that demonstrated efficacy of PBT-1 and animal modelsgroup 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 beare incorporated into theour 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. 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 300several hundred compounds that had been developed by us at such timetime. It has been designed to have an improved safety and pharmacokinetic profile 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.testing. PBT-2 has completed formalinitial preclinical toxicology testing 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. SeeIn early 2006, we also successfully completed a second Phase I multi-dose escalation safety clinical trial of PBT-2. On May 5, 2006 we announced that we received an expert report in respect of the Phase I trials for PBT-2. The expertreport was prepared by Dr. Craig Ritchie, psychiatrist and Director of Mental Health Clinical Trials at University College London and a clinical advisor to our company. Dr. Craig Ritchie concluded that the Phase I results provide the confidence needed to move forward to formal Phase II testing in people with Alzheimer’s disease. On May 11, 2006, we announced our plans to move forward with a Phase IIa clinical trial for PBT-2 in patients with Alzheimer’s disease. The study is expected to commence enrollment in the fourth quarter of 2006, subject to final regulatory approval, and assuming such start date, results are expected to be reported by the end of 2007. For additional details regarding our clinical trials see Item 4.A. "Information“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.

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 grant and 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 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, export, 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.

2730

In addition to patent protection, we rely on unpatented trade secrets, and know-how and other confidential information as well as 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 obsolete or 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, the Medical Products Agency, or MPA, in Sweden and the European Medicines Evaluation 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, EMEA and 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 pharmacokinetics 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.

2831

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 formalthe initial preclinical toxicology testing of PBT-2 that is required to move a compound into 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. SeeIn early 2006, we also successfully completed a second Phase I multi-dose escalation safety clinical trial of PBT-2. On May 5, 2006, we announced that we received an expert report in respect of the Phase I trials for PBT-2. The expert report was prepared by Dr. Craig Ritchie, psychiatrist and Director of Mental Health Clinical Trials at University College London and a clinical advisor to our company. Dr. Craig Ritchie concluded that the Phase I results provide the confidence needed to move forward to formal Phase II testing in people with Alzheimer’s disease. On May 11, 2006, we announced our plans to move forward with a Phase IIa clinical trial for PBT-2 in patients with Alzheimer’s disease. The study is expected to commence enrollment in the fourth quarter of 2006, subject to final regulatory approval, and assuming such start date, results are expected to be reported by the end of 2007. For additional details regarding our clinical trials see Item 4.A. "Information“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. We cannot make any assurances that we will complete the Phase I program for PBT-2 or enter further clinical trials with 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-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.
 
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 PBT2PBT-2 or any futureother development or product candidate (including PBT-1) will be safe or effective when administered to patients.
32

 
Manufacturing and Raw Materials
 
We have used a third party manufacturer to produce the primary drug product (API) and secondary drug forms for our large-scale, preclinical and clinical PBT-1 and PBT-2 trials, and we expect that we will use a third party manufacturer for any future product candidates. WeDespite some difficulties in obtaining PBT-1 raw material with an appropriate impurity profile, we have not faced any difficulty in obtaining PBT-2 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. We cannot make any assurances that we will be able to manufacture sufficient quantities of PBT-2 or any futureother development or product candidates (including PBT-1)candidate in a cost-effective or timely manner. Any delays in production would delay our pre-clinical and human clinical trials, which could have a material adverse effect on our business, financial condition and results of operations. We also cannot make any assurances that we will 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 design and develop new synthetic pathways for most, if not all, of the products that we currently intend to develop.develop or may develop in the future. 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 material 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, approved our application for funding under the Biotechnology Innovation Fund (BIF) grant in the amount of A$227,252 for research into the development of an immunotherapy for Alzheimer’s disease. The research under this grant was completed infinished at the end of January 2005 followinghaving achieved the completion of certain project milestones stipulated in the grant,scientific milestone demonstrating that a mouse could generate antibodies that preferentially recognize dimerized βAmyloid. ‘toxic linked’ forms of beta-amyloid and not the endogenous monomeric form of beta amyloid.
 
In the first quarter of 2004, we were granted a START grant from the IR&D Board to support further development of PBT-2 and other Alzheimer’s disease research up to an amount of A$1.35 million. The grant iswas 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 such 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. AsThis grant was completed in December 2005 and we have received the entire amount of September 30, 2005, we were entitled to approximately A$1.15 million under this grant.

Commercial Collaboration
In March 2003, we announced a collaboration with Schering A.G. (FSE:SCH, NYSE:SHR) of Germany to fund and license research discoveries, particularly in the area of imaging and diagnostics, under project agreements between us and Neurosciences Victoria Ltd. and a separate research and 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. See Item 4A. “Information on the Company - History and Development of the Company.”
 
In August 2003, utilizing the grant we received from the Commonwealth Government of Australia under the BIF, we entered into an agreement with Prima Biotechnology Limited, or Prima, through its collaborative research partner, the AustinMacfarlane Burnet Institute for Medical Research and Public Health, known as the Burnet Research Institute at Austin, together with the University of Melbourne and the 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'sPrima’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 commercialintellectual property rights to theour monoclonal antibodies and Prima and us will be the joint owners of any new intellectual property arising fromthat were used for the collaboration.

A. Operating ResultsOPERATING 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 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 commenceddisease and in early August 2003, our planned phase II human clinical trialPBT-2 compound was announced as a new lead metal protein attenuating compound, or MPAC, molecule 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. disease.
On April 11, 2005, we announced that we would not proceed with the PLACQUEscheduled Phase II/III study of PBT-1 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.mutagenic potential. 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. On June 30, 2005, our Board of Directors determined that the core intellectual property relating to PBT-1 had been impaired and the carrying value was written-off.
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 andWe completed two Phase I clinical trials for Alzheimer's disease. Formal preclinical toxicology testing forstudies of PBT-2 has been completed(for details see Item 4A. “Information on the Company - History and in March 2005, we commenced a seriesDevelopment of Phase I clinical trials at a facility associated with the Utrecht University Hospital in Utrecht, the Netherlands. On November 7, 2005,Company”) and on May 11, 2006, we announced the successful completion of the firstour plans to move forward with a Phase IIIa clinical trial for PBT-2 a double blind, placebo-controlled single dose escalationin patients with Alzheimer’s disease. The study, to be conducted on 55 healthy, male volunteers between the ages of 18 and 50, which was designed toin several sites in Sweden, will evaluate the safety and tolerability of PBT-2, as well as measures of the drug’s mechanism of action and pharmacokineticsindicators of PBT-2.

Additionally, the pharmacokinetic analysis demonstrated that the drug exposure increased predictably and in a linear manner, bothend 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.2007.

Recently Issued But Not Yet Adopted Accounting Pronouncements Applicable To Us

Australian Pronouncements

On July 3, 2002, the Australian Financial Reporting Council announced that Australia would adopt International Financial Reporting Standards. Our management has been assessing the significance of these changes and preparing for their implementation. We will beStandards, or IFRS, under which we are required to prepare consolidated financial statements that comply with the Australian equivalents to International Financial Reporting Standards,IFRS, or IFRS,A-IFRS, for reporting periods beginning on or after January 1, 2005. Accordingly, our first half-year reportannual consolidated financial statements prepared under Australian IFRS will beA-IFRS are for the half-year reporting period ending December 31, 2005, and our firstfiscal year ended June 30, 2006 included in this annual financial report prepared under Australian IFRS will bereport. Comparative figures for the fiscal year endingended June 30, 2006.2005 have been adjusted to reflect such change in accounting policies.

We have completed a studyIn applying A-IFRS, we relied on an exception to such accounting standards with respect to the valuation of options issued to employees and directors. Under AASB Standard No. 2, the fair value of share options issued to employees and directors is determined at grant date and expensed over the expected vesting period of the options.  Upon transition to A-IFRS, we elected not to retrospectively recognize share based payments that were granted before November 7, 2002 and share based payments granted after November 7, 2002 that vested before January 1, 2005.  As a result of this election, we did not apply a Black Scholes or Barrier Pricing Model to the affected equity.  Had we elected to retrospectively recognize the value of this equity, the issued capital, share based payments reserve and the accumulated deficit would have increased.  This would not have had any effect on the overall total equity of our company.

The likely impact of the accounting policy changesA-IFRS on theour results and financial position of the consolidated entity has been determined and disclosedare described in Note 1(t) (unaudited)1(s) to theour consolidated financial statements.

United States Pronouncements

On December 16, 2004, the Financial Accounting Standards Board, or FASB, issued Statement of Financial Accounting Standards, (“SFAS”) No.or SFAS 123 (revised 2004), "Share-Based Payment",“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, while 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.values on the date of grant. 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
We adopted the modified prospective method of SFAS 123(R) effective for us commencing July 1, 2005.2005 in which compensation cost is recognized beginning with the effective date (a) based on the requirements of SFAS 123(R) for all share-based payments granted after the effective date and (b) based on the requirements of SFAS 123 for all awards granted to employees prior to the effective date of SFAS 123(R) that remain unvested on the effective date.

AsPrior to July 1, 2005, as permitted by SFAS 123, we currently accountaccounted 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.method, or APB No. 25. 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, hadHad we adopted SFAS 123(R) in prior periods, the impact of that StandardSFAS 123(R) would have approximated the impactincreased our loss by $A1,708,925. As a result of adopting SFAS 123, as disclosed in Note 25(a) of our financial statements included in this Report.

In December 2004, the FASB issued SFAS No. 153, "Exchanges of Nonmonetary Assets - an amendment of APB Opinion No. 29," or 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 asset exchanges occurring in fiscal periods beginning after June 15, 2005. The new standard will be effective for us commencing123(R) on July 1, 2005. At this time,2005, our U.S. GAAP loss before income taxes and net loss for the year ended June 30, 2006 was A$76,469 higher than if we do not anticipate that the adoption of this statement will have a material effect on our consolidated financial position or results of operations.had continued to account for share-based compensation to employees and directors under APB No. 25.

34

In May 2005, the FASB issued FASB StatementSFAS No. 154 “Accounting Changes and Error Corrections:Corrections,” or SFAS 154, a replacement of APB Opinion No. 20 “Accounting Changes and FASB StatementSFAS No. 3”, or SFAS 154, which requires companies3 “Reporting Accounting Changes in Interim Financial Statements,” effective for fiscal years beginning after December 15, 2005, and was required to apply voluntary changes in accounting principles retrospectively whenever it is practicable.be adopted by our company as of fiscal year beginning June 30, 2006. 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 anticipateour management reasonably believes that the adoption of SFAS 154 will not have a material effect on our consolidated financial position or results of operations.


37

In July 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes,” FIN 48, as an interpretation of SFAS 109. FIN 48 clarifies the accounting for uncertainty in income taxes recognized by prescribing a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 also provides guidance on de-recognition of tax benefits previously recognized and additional disclosures for unrecognized tax benefits, interest and penalties. The evaluation of a tax position in accordance with FIN 48 begins with a determination as to whether it is more likely than not that a tax position will be sustained upon examination based on the technical merits of the position. A tax position that meets the more-likely-than-not recognition threshold is then measured at the largest amount of benefit that is greater than fifty-percent likely of being realized upon ultimate settlement for recognition in the financial statements. FIN 48 is effective no later than fiscal years beginning after December 15, 2006, and is required to be adopted by our company on July 1, 2007. We are currently assessing the impact of the adoption of FIN 48.
In September 2006, the SEC issued Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements when Qualifying Misstatements in Current Year Financial Statements,” or SAB 108, which provides interpretive guidance on the consideration of the effects of prior year misstatements in quantifying current year misstatements for the purpose of a materiality assessment. SAB 108 is effective for companies with fiscal years ending after November 15, 2006 and is required to be adopted by our company as of our fiscal year ended June 30, 2007. However, early application is encouraged in any report for an interim period of the first fiscal year ending after November 15, 2006, filed after the publication of this guidance. We are currently assessing the impact of the adoption of SAB 108.
In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements,” or SFAS 157. SFAS 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS 157 applies under other accounting pronouncements that require or permit fair value measurements, the FASB having previously concluded in those accounting pronouncements that fair value is the relevant measurement attribute. Accordingly, SFAS 157 does not require any new fair value measurements. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. SFAS 157 is required to be adopted by our company on July 1, 2008. We are currently assessing the impact of the adoption of SFAS 157.

Critical Accounting Policies

We prepare our financial statements in accordance with A-GAAP.A-IFRS. 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 ofto the consolidated 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-GAAPA-IFRS are discussed below.

Recoverable amount of non-current assets. Each reporting period, our Board of Directors assesses the recoverable amount of all non-current 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 recoverableRecoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated based on expected netfuture cash flows are discounted to their present valuesvalue using a market-determined, risk-adjusted discounted rate.pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.

On June 30, 2005, following theour 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. 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.

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

Revenue 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. To date, our revenue has consisted of interest income, which is recognized as earned when collectibility is reasonably assured.

·Interest income is recognized as earned when collectibility is reasonably assured.
Other income recognition. We recognize other income to the extent that it is probable that the economic benefits will flow to us and the other income can be reliably measured.

 ·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. RevenueOther income 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. RevenueOther income for each milestone achieved is fixed at the initiation of the program.

36

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

 ·Corporate partner revenues areincome is comprised of amounts received for certain research and development activities under our collaboration with Schering A.G. and Neurosciences Victoria Ltd. Revenues areSuch income is 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.

Share-based payments. Equity-settled share-based payments granted after November 7, 2002 that were unvested as of January 1, 2005 are measured at fair value at the date of grant. Fair value is measured by use of the Black-Scholes model (for options without market conditions) or the Barrier Pricing model (for options with market conditions). The expected life used in the model has been adjusted, based on management’s best estimate, for the effects of non-transferability, exercise restrictions, and behavioural considerations. The date used to value share-based payments for non-employees may be different to the grant date used to value employee share-based payments where service conditions apply. The fair value of the equity-settled share-based payments is expensed on a straight-line basis over the vesting period for each tranche of equity, based on our estimate of shares that will eventually vest.

Revenues from ordinary activities increaseddecreased to A$2,653,113762,023 for the year ended June 30, 2006 from A$892,135 for the year ended June 30, 2005, froma decrease of A$2,321,227130,112, or 14.6%. Revenues consisted of A$762,023 and A$892,135 in interest income in the years ended June 30, 2006 and 2005 respectively. The decrease in revenues in the 2006 fiscal year was attributable to lower interest income as a result of a reduction in cash and cash equivalents.
Other Income
Other income decreased to A$288,263 for the year ended June 30, 2004, an increase2006 from A$1,760,978 for the year ended June 30, 2005, a decrease of A$331,886,1,472,715, or 14.3%83.6%.

Other income 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. RevenuesThe decrease in other income in the 2006 fiscal 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 iswas 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,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.2005.

DepreciationResearch and amortizationdevelopment expenses (including research and development expenses paid to related parties) remained substantially consistent at A$1,165,2277,613,045 for the year ended June 30, 2006 from A$7,687,596 for the year ended June 30, 2005. Research and development expenses in the year ended June 30, 2005 consisted of expenses related to clinical trials for our PBT-1 compound as a treatment for Alzheimer’s disease that ceased in April 2005 and A$911,250 of expenses associated with our licensing and research collaboration with Schering A.G. and Neurosciences Victoria Ltd. that was concluded in June 2005. Research and development expenses in the year ended June 30, 2006 consisted of expenses associated with two clinical trials for our PBT-2 lead compound and the pre-clinical programs for our other compounds. In fiscal year 2007, our research and development will be primarily directed at PBT-2, including the Phase IIa clinical trial for PBT-2. In addition, further expenditure is expected in developing our other potential lead compounds at a pre-clinical level.

Personnel expenses
Personnel expenses decreased to A$3,418,008 for the year ended June 30, 2006 from A$5,750,929 for the year ended June 30, 2005, compareda decrease of A$2,332,921, or 40.6%. The decrease in personnel expenses in the 2006 fiscal year was primarily due to the closure of our U.S. office in August 2005 and a reduction in staff in the United States and Australia. Personnel expenses in the 2005 fiscal year include A$1,195,0062,211,792 in cash and equity payments (including the expensing of options grants) made to Dr. Jon Alsenas, our former U.S. based director and Chief Executive Officer, and A$449,800 in equity issued to a consultant. The decrease in personnel expenses in the 2006 fiscal year was offset in-part by employee salary increases and the grant of options to directors and employees at the beginning of the 2006 calendar year. Only a portion of the total fair value of such options granted to our directors and employees was recognized as personnel expenses for the fiscal year ended June 30, 2006 and a further A$924,782 will be recognized in future fiscal years.
Intellectual property expenses
Intellectual property expenses decreased to A$466,426 for the year ended June 30, 2004.

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 of2006 from A$10,388,339.
Patents, research and development expenses
Patents, research and development expenses increased to A$7,687,596729,583 for the year ended June 30, 2005, froma decrease of A$5,232,581263,157, or 36.1%. The decrease in intellectual property expenses in the 2006 fiscal year was primarily due to our company handling more of the work associated with patent applications in-house in the 2006 fiscal year, while we engaged more external consultants in the 2005 fiscal year. In addition, in the 2005 fiscal year a new patent application was filed at a cost of approximately A$100,000.
Audit fees
Audit fees remained substantially consistent at A$205,815 for the year ended June 30, 2004, an increase of2006 from 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$1,047,448202,032 for the year ended June 30, 2005, froman increase of A$1,650,4673,783, or 1.9%.
Travel expenses
Travel expenses decreased to A$212,184 for the year ended June 30, 2004, a decrease of2006 from 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$2,438,303432,316 for the year ended June 30, 2005, froma decrease of A$1,060,730220,132, or 50.1%. The decrease in travel expenses in the 2006 fiscal year was due, in part, to the cessation of travel between the United States and Australia of Dr. Jon Alsenas, our former U.S. based director and Chief Executive Officer, following his resignation in June 2005, which expenses amounted to A$141,683 in the 2005 fiscal year.
Marketing expenses
Marketing expenses decreased to A$134,750 for the year ended June 30, 2004, an increase of2006 from 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$1,607,892442,920 for the year ended June 30, 2005, froma decrease of A$1,706,809308,170, or 69.6%. The decrease in marketing expenses in the 2006 fiscal year was primarily due to the cessation of services provided to our U.S. subsidiary by a public relations and marketing consultant following the closure of our U.S. office in August 2005.

43

Depreciation expenses
Depreciation expenses increased to A$118,196 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 amounting2006 compared 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$562,12365,223 for the year ended June 30, 2005, froman increase of A$419,70852,973, or 81.2%. The increase in depreciation expenses in the 2006 fiscal year is the result of the acceleration of leasehold improvement depreciation in line with the life of the lease agreement.
Amortization expenses
We recorded amortization expenses relating to PBT-1 core intellectual property of A$83,200 for the year ended June 30, 2004, an increase2005. As a result of the impairment of the carrying value of our core intellectual property relating to PBT-1 to nil recoverable amount on June 30, 2005, we did not incur any amortization expenses relating to our intellectual property in the 2006 fiscal year.
Other expenses
Other expenses (including other expenses paid to related parties) decreased to A$142,415,824,625 for the year ended June 30, 2006 from A$1,204,930 for the year ended June 30, 2005, a decrease of A$380,305, or 33.9%46.1%. The increasedecrease in corporate complianceother 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 similaris primarily due to those forreduced expenditures following the 2005 fiscal year.closure of our U.S. office in August 2005.

Impairment of intangible assets
 
Impairment of intangible assets was A$10,388,339786,240 for the year ended June 30, 2005. This was a one-off non-cash expense incurred as a result of the consolidated entity’sour 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.

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.

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’ 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 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.

We are a development stage company and have had no sales income to date, and as of June 30, 20052006 our accumulated deficit totaled A$50,473,473.49,235,574. From inception until our initial public offering in March 2000 we financed our operations primarily through borrowings from two of our then 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, 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 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 ($26.4 million net of issuance costs) in a private placement in the United States, which amount 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.million (approximately A$32 million). To 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.

Under the ten year contract we 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, as a bonus package, to issue to Professor Bush 1,650,000 ordinary shares (of which 825,000 ordinary shares were issued during the 2004 fiscal year and 825,000 ordinary shares were issued in August 2005)during the 2006 fiscal year) and to grant Professor Bushto him options to purchase 825,000 ordinary shares at an exercise price of A$0.50 per share (of which options to purchase 412,000 ordinary shares were granted during the 2004 fiscal year and options to purchase 413,000 ordinary shares were granted during the 2006 fiscal year).

In addition, subject to the achievement of certain milestones, Professor Bush, is entitled to purchase up to 5,000,000 additional ordinary shares at a price per share that is 10% below the mean market price of our ordinary shares during the 30-day period prior to their purchase. Once a milestone has been achieved, up to 2,500 ordinary shares out of the total tranche of ordinary share to which he becomes entitled may be purchased each six months after such achievement. The first milestone has been achieved (the publication of results of a Phase II trial) and as such, Professor Bush is now entitled to purchase up to 1,250,000 ordinary shares in accordance with the foregoing terms. The ordinary shares issued and options granted to Professor Bush under the agreement are subject to certain resale restrictions.

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 beenwere 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, whileand P.N.G. holds certain patent rights on the uses of clioquinol for Europe and other territories.

P.N.G. is also entitled to receive 2% of our worldwide income from PBT-2.

We also have aOur remaining commitment under a three year lease for our principal office that we moved toexpires in June 2004. The total lease commitment over the three year period2007 is A$306,781.92,726.

We believe our existing cash and cash equivalents as well as anticipated cash flow from government grants, interest income and potential option exercises will be sufficient to support our current operating plan to 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:

·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 (absorption, distribution, metabolism, and excretion) 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.tolerated. 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.development candidate. 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 haveIn early 2006, we also successfully completed three out of four stages of a second Phase I multi-dose escalation safety clinical trial of PBT-2 in 32 elderly, healthy, male and female volunteers. We anticipate completingvolunteers (45 to 75 years). On May 5, 2006, we announced that we received an expert report in respect of the final dosing stage in December 2005. In addition,Phase I trials for PBT-2. The expert report was prepared by Dr. Craig Ritchie, psychiatrist and Director of Mental Health Clinical Trials at University College London and a clinical advisor to our company. Dr. Craig Ritchie concluded that the preclinical toxicology studies and GMP manufacturing development required forPhase I results provide the confidence needed to move forward to formal Phase II testing in people with Alzheimer’s disease. For additional details regarding our clinical trials see Item 4.A. “Information on the Company - History and Phase III clinical studiesDevelopment of PBT-2 are concurrently underway.the Company.” We anticipate that expenditures for the Phase III program for PBT-2 will amount to A$700,000,5,501,000 however such expenditures may adjustchange due to numerous factors. For information on such factors, see Item 5.C. "Operating“Operating and Financial Review and Prospects - Research and Development, Patents and Licenses." We expect to fund such expenditures from our working capital.

We believe our existing cash and cash equivalents as well as anticipated cash flow from government grants, interest income and potential option exercises will be sufficient to support our current operating plan to March 31, 2007; 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:
·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.
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 candidate. In addition, we will require additional funds to pursue regulatory clearances, and defend our intellectual property rights, establish commercial scale manufacturing facilities, develop marketing and sales capabilities and fund operating expenses. We intend to seek such additional funding through public or private financings and/or through strategic alliances or other arrangements with corporate partners. We cannot, however, be certain that such additional financing will be available from any sources on acceptable terms, or at all, or that we will be able to establish new strategic alliances or other arrangements with corporate partners on acceptable terms, or at all. Any shortfall in funding could result in our having to curtail our operations, including our research and development activities, which could have a material adverse effect on our business, financial condition and results of operations.

Our failure to raise additional capital before March 2007 would have a material adverse effect on our company’s ability to continue as a going concern and to achieve its business objectives. Our auditors have included a going concern uncertainty paragraph in their report. The accompanying financial statements do not include any adjustments relating to the recoverability of the carrying amount of recorded assets or the amount of liabilities that might result should we be unable to continue as a going concern.

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 LicensesRESEARCH 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$5,232,5817,613,045 and A$1,717,7707,687,596 during the years ended June 30, 2006 and 2005, 2004 and 2003, respectively. In addition to these expenses, A$143,525 was spent in relation to patent costs during the year ended June 30, 2003. We did not incur any costs classified as patent costs during the years ended June 30, 2005 or 2004. Costs associated with patent applications and defense of patent applications are classified as legal expenses.intellectual property expenses and amounted to A$466,426 and A$729,583 during the years ended June 30, 2006 and 2005, respectively.

46

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 and/or clinical agreements. 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(e)4 to the consolidated 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 or revised 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. Under this collaboration, we, through our contractor the University of Melbourne, undertook specific research and development projects, and Schering A.G. funded up toapproximately A$2.7 million of our research and development costs over the life of thesuch projects and agreed to pay additional milestone payments and royalties from discoveries.discoveries resulting from such projects. 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 on the Company - History and Development of the Company.”

We announced on July 26,In 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$1.4 million during theover three year period commencing January 1, 2001,years 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.

We announced onIn 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. The research under this grant was initially to be completed over a two year period until September 1, 2005 and such period was subsequently extended until December 2005. Under the terms of the grant, we are to receivereceived A$1.35 million duringover the two-year period commencing September 1, 2003,term of the grant for up to 50% of the project costs related to the toxicology testing program and early human trials.

Introduction
 
Our Board of Directors is elected by and accountable to our shareholders. Our Board of Directors’ responsibilities are divided into operating activities, financial and capital markets activities and scientific activities. The Chairman of our Board of Directors, currently Mr. Geoffrey Kempler, is responsible for the management of the Board of Directors and its functions.
 
Non-Executive and Independent Directors

Our Board of Directors currently has five directors, of which three are non-executive directors under Australian law.

In addition, in general, under NASDAQ Marketplace Rules promulgated pursuant to the Sarbanes-Oxley Act of 2002, as 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 our 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. 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, George Mihaly and Peter Marks qualifies as an independent director under the ASX, NASDAQ Stock Market and Securities and Exchange Commission requirements.

Stock Option Plans
 
Employee and Consultants Option Plan 2000
 
In November 2000, we adopted our Employee and Consultants Option Plan 2000, or the 2000 Plan. The 2000 Plan is designed to reward executives, employees and consultants for their contributions to our company and to provide a method of retaining key personnel for the growth and development of our intellectual property rights. Under the 2000 Plan, the number of ordinary shares issuable upon exercise of options granted under the 2000 Plan from time to time, that have not expired and have not been exercised, may not exceed 3,000,000. Options granted under the 2000 Plan were exercisable (irrespective of the date of grant) at any time from 12 months after the date of grant until June 30, 2005, at an exercise price of A$0.50 per share. The options cannot be transferred and will not be quoted on the ASX.
 
During the 2005 fiscal year, no options were granted or exercised under the 2000 Plan. On June 30, 2005, all outstanding options granted under the 2000 Plan expired. Weexpired and we do not intend to grant any further options under the 2000 Plan.

Under the terms of a research funding and intellectual property assignment agreement dated December 1, 2000, between us andprovide the University of Melbourne we were requiredcertain funding for the research projects. We have provided or will provide to pay the University of Melbourne for research projectsfunding in 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 expiration of this agreement, the parties have entered into a second research funding and intellectual property assignment agreement, which is deemedamount equal 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) during each of the years December 2004 to November 2005 and December 2005 to November 2006.

On February 8, 2000, we entered into ana patent assignment agreement for the assignment of patents and intellectual property licensing with BRI. The agreement provides for the assignment of various patent applications and patent rights from BRI to us. In consideration of the assignment of the patents, we are required to pay BRI a royalty of 1.5% on the net invoiced 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 licensee or sub-licensee we appoint to utilize such patents, or a minimum of A$2,000 a year. If the patent rights are assigned before a total of A$20,000 has been paid as royalties, the difference between the royalties paid and A$20,000 must be paid to BRI.

On January 1, 2001, we entered into a license agreement with GHC, whereby we obtained an exclusive license with respect to certain patents that permits us to sublicense the patent rights to others. 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.

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. Under this collaboration, we, through our contractor the University of Melbourne, undertook specific research and development projects, and Schering A.G. funded approximately A$2.7 million of our research and development costs over the life of such projects and agreed to pay additional milestone payments and royalties from discoveries resulting from such projects. 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 on the Company - History and Development of the Company.”

See Item 8A. “Financial Information - Financial Statements and Other Financial Information - Legal Proceedings.”
 
D. Exchange ControlsEXCHANGE 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. These limitations are set forth in the Australian Foreign Acquisitions and Takeovers Act, or the Takeovers Act.

76

Under the Takeovers Act, as currently in effect, any foreign person, together with associates, is prohibited from acquiring 15% or more of the shares in 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 the shares it has acquired within a specified period of 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$50,000,000; or (ii) any direct or indirect ownership interest in Australian residential real estate.

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

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

Australian law requires the transfer of shares in our company to be made in writing. No stamp duty will be payable in Australia on the transfer of ADRs.
 
E. TaxationTAXATION
The following is a discussion of Australian and United States tax consequences material to our shareholders. To the extent that the discussion is based on tax legislation which has not been subject to judicial or administrative interpretation, the views expressed in the discussion might not be accepted by the tax authorities in question or by court. The discussion is not intended, and should not be construed, as legal or professional tax advice and does not exhaust all possible tax considerations.
77

 
Holders of our ADSs should consult their own tax advisors as to the United States, Australian Tax Consequencesor other tax consequences of the purchase, ownership and disposition of ADSs, including, in particular, the effect of any foreign, state or local taxes.

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 byof the absolute beneficial ownersownership 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 ADRsADSs for Australian Taxation Purposes
 
Holders of our ADSs held by a U.S. holder will beare treated for Australian taxation purposes as held under a ‘bare trust’ for such holder. Consequently,the owners of the underlying ordinary shares will be regarded as owned by the ADS holder for Australian income tax and capital gains tax purposes. DividendsTherefore, dividends paid on the underlying ordinary shares will also be treated for Australian tax purposes as dividendsif they were paid directly to the ADS holder,owners of ADSs, and the disposal of ADSs will be treated for Australian tax purposes as the person beneficially entitled to those dividends. Therefore, indisposal of the underlying ordinary shares. In the following analysis we discuss the application of the Australian income tax consequencesand capital gains tax rules 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’ to the extent of tax paid on company profits. Fully franked dividends are not subject to dividend withholding tax. Dividends payable by our companythat are not franked or are partly franked and are paid to non-Australian resident stockholders will beare subject to dividend withholding tax, but only to the extent the dividends are unfranked. Dividendnot franked.
Dividends paid to a non-resident stockholder are subject to withholding tax will be imposed at 30%, unless athe stockholder is a resident of a country with which Australia has a double taxation agreement. UnderIn accordance with the provisions of the current Double Taxation Convention between Australia and the United States, the maximum rate of 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, where the U.S. resident holds less than 10% of the voting rights ofin our company, unlessor 5% where the sharesUS resident holds 10% or more of the voting rights in our company. The Double Taxation Convention between Australia and the United States does not apply to limit the rate tax on dividends where the ADSs are effectively connected to a permanent establishment or a fixed base carried on by the owner of the ADSs 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%.
78

 
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. 
 
Under a proposed amendment to Australian tax law that is currently before Federal Parliament, if enacted, the exemption for non-resident stockholders would be extended. If aenacted in the current draft form, non-Australian resident stockholder did own a 10% or more interest, that stockholder wouldstockholders will not be subject to Australian capital gains tax on the capital gain made on a disposal of our shares, unless they, together with associates, hold 10% or more of our issued capital, tested either at the time of disposal or over any continuous 12 month period in the 24 months prior to disposal, and the same extent asvalue of our shares at the time of disposal are wholly or principally attributable to Australian resident stockholders. real property assets.
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.tax on U.S. residents. Australian capital gains tax applies to net capital gains at a taxpayer’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’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.
79

 
Dual Residency
 
If a stockholder were a resident of both Australia and the United States under those 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 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’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 ConsequencesUNITED 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 (as defined below) 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, and 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’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.
 
7680

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.
 
For purposes of this summary, the term “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. Subject 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. 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 of 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.
 
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’s U.S. federal income tax liability (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. Dividends generally will be treated as foreign-source passive income or financial services income for U.S. foreign tax credit purposes. U.S. Holders should note that recently enacted legislation eliminates the “financial services income” category with respect to taxable years beginning after December 31, 2006. Under this legislation, the foreign tax credit limitation categories will be limited to “passive category income” and “general category income.” A U.S. Holder will be denied a foreign tax credit with respect to Australian income tax withheld 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-day31-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.
 
81

Subject to certain limitations, “qualified dividend income” received by a noncorporate U.S. Holder in tax years beginning on or before December 31, 20082010 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 passive foreign investment company rules discussed below, 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.
 
7882

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.
 
Passive Foreign Investment Companies
 
There is a substantial risk that we are a passive foreign investment company, or PFIC, for U.S. federal income tax purposes. Our treatment as a PFIC could result in a reduction in the after-tax return to the U.S. Holders of our ADRs and may cause a reduction in the value of such securities.
 
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, 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. As a result of our substantial cash position and the decline in the value of our stock, we believe that we became a PFIC in 2004during the taxable year ended June 30, 2005, and will once again qualify as a PFIC for the taxable year ended June 30, 2006, under a literal application of the asset test that looks solely to market value.

If we are a PFIC, dividends will not qualify for the reduced maximum tax rate, discussed above, and, 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 theyour holding period for such ADRs,

7983


 ·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 treat its holding period for its ADRs as beginning on the day following the last day of the last taxable year in which we were a PFIC.

If the ADRs are considered “marketable stock” and if you elect to “mark-to-market” your ADRs, you would not be subject to the rules described above. 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,loss (except that loss is treated as capital loss to the extent in excess ofthe loss exceeds the net mark-to-market gains, wouldif any, that a U.S. Holder included in income with respect to such ordinary shares in prior years). However, gain or loss from the disposition of ordinary shares (as to which a “mark-to-market” election was made) in a year in which we are no longer a PFIC, will be treated as capital gain or 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.

8084

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’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.banks in Australia. Our management believes that the financial institutions that hold our investments are financially sound and accordingly, minimal credit risk exists with respect to these investments. 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$7.35,943,335 million in time deposits held in U.S. dollars as of June 30, 2005.2006. A hypothetical 10% adverse movement in end-of-period exchange rates would reduce the cash balance by approximately A$0.7 million.594,334.

8286

We have engaged an external consultant to assist us to optimize our interest returns and manage our foreign 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 could have a material impact on our operating results. At June 30, June 2005,2006, we had US$12,191253,213 and EUR$314,407168,428 in payables. A hypothetical 10% adverse movement in the USU.S. and EUR exchange rates could increase the cost of these payables by A$51,419.63,656.

ITEM 15.CONTROLS AND PROCEDURES

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 Securities 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 U.S. Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported 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.
87

 
We evaluated the effectiveness of our disclosure controls and procedures under the supervision of 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 disclosure controls and procedures were ineffective in that 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 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-GAAPA-IFRS and U.S. GAAP.
 
83

All internal control systems no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective may not prevent or detect misstatements and can provide only reasonable assurance with respect to financial statement preparation and presentation. 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 degree of compliance with the policies or procedures may deteriorate.

[LETTERHEAD OF DELOITTE TOUCHE TOHMATSU]
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
DELOITTE TOUCHE TOHMATSU

To The Board of Directors and Shareholders of Prana Biotechnology Limited

We have audited the accompanying consolidated statements of financial positionbalance sheets of Prana Biotechnology Limited (a company incorporated in Victoria, Australia) and subsidiaries (a development stage company) (the “Company”) as of June 30, 20052006 and 20042005 and the related consolidated statements of financial performance,operations,  stockholders' equity, and cash flows and changes in stockholders' equity for each of the threetwo years in the period ended June 30, 2005, and for the period from November 11, 1997 (date of inception) to June 30, 2005.2006. 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, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of Prana Biotechnology Limited and subsidiaries as of June 30, 20052006 and 2004,2005, and the results of their operations and their cash flows for each of the threetwo years in the period ended June 30, 2005, and for the period from November 11, 1997 (date of inception) to June 30, 2005,2006, in conformity with accounting principles generally accepted in Australia.the Australian Equivalents to International Financial Reporting Standards.

Accounting principles generally accepted in AustraliaThe Australian Equivalents to International Financial Reporting Standards vary in certain significant respects from accounting principles generally accepted in the United States of America. Information relating to the nature and effect of such differences is presented in Note 2526 to the consolidated financial statements.

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company's recurring losses from operations and negative cash flows from operations raise substantial doubt about its ability to continue as a going concern. Management's plans concerning these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

On March 28, 2000, the Company completed its initial public offering in Australia and listed on the Australian Stock Exchange (“ASX”). In September 2002, the Company’s shares were approved for listing on the NASDAQ Capital Market (symbol: PRAN).

Financial Reporting Framework

The financial report is a general purpose financial report, which has been prepared in accordance with the requirements of the Corporations Act 2001, Accounting Standards and Urgent Issues Group Consensus ViewsInterpretations, and complies with other requirements of the law. Accounting Standards include Australian equivalents to International Financial Reporting Standards (‘A-IFRS’). Compliance with A-IFRS ensure that the consolidated financial statements and notes of the consolidated entity comply with International Financial Reporting Standards (‘IFRS’).

The financial report has been prepared on the basis of historical cost and except where stated, does not take into account changing money values or current valuations of non-current assets.cost. Cost is based on the fair values of the consideration given in exchange for assets.

In the application of A-IFRS management is required to make judgments, estimates and assumptions about carrying values of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and various other factors that are believed to be reasonable under the circumstance, the results of which form the basis of making the judgments. Actual results may differ from these estimates. The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised if the revision affects only that period, or in the period of the revision and future periods if the revision affects both current and future periods.

Judgments made by management in the application of A-IFRS that have significant effects on the financial statements and estimates with a significant risk of material adjustments in the next year are disclosed, where applicable, in the relevant notes to the financial statements.

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

The consolidated entity changed its accounting policies on July 1, 2005 to comply with A-IFRS. The transition to A-IFRS is accounted for in accordance with Accounting Standard AASB 1: First-time Adoption of Australian Equivalents to International Financial Reporting Standards, with July 1, 2004 as the date of transition. An explanation of how the transition from superseded policies to A-IFRS has affected the consolidated entity's financial position, financial performance and cash flows is discussed in Note 1(s).

The accounting policies set out below have been applied in preparing the financial statements for the year ended June 30, 2006, the comparative information presented in these financial statements for the year ended June 30, 2005, and in the preparation of the opening A-IFRS balance sheet at July 1, 2004 (as disclosed in Note 1(s)), the consolidated entity's date of transition.

Going Concern Basis

The consolidated entity is a development stage medical biotechnology company and as such expects to be utilizing cash until its research activities have become marketable. As at 30 June 2006, the consolidated entity have accumulated losses of $49,235,574, and have incurred negative cash flows from operations of $11,651,215, in the current year. The consolidated entity have also experienced a reduction from its cash position of $21,453,304 as at 30 June 2005 to $10,013,778 as at 30 June 2006.

Although the consolidated entity do not have sufficient cash resources to fund their current level of activities for at least the next 12 months, and there are uncertainties as to the exact timing and form of additional fund raising, the directors believe that there is a reasonable expectation that they can raise additional cash resources and or reduce operating costs during the 2007 fiscal year. These financial statements have, therefore, been prepared on a going concern basis which contemplates the continuity of normal business activities and the realization of assets and settlement of liabilities in the ordinary course of business.
F-6

PRANA BIOTECHNOLOGY LIMITED
(A Development Stage Enterprise)
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - in Australian dollars (unless otherwise noted)
The directors believe that the going concern basis of preparation is appropriate given the following reasons:

·The most recently prepared cash flow forecasts prepared by management and reviewed by the directors indicate that the consolidated entity will have sufficient cash to meet their current operating requirements until at least March 2007, being the expected signing date of the Director’s Declaration for the half-year ending 31 December 2006.
·Since inception, the consolidated entity have been able to raise funds to advance their research processes. To date, the consolidated entity have raised in excess of $55 million in equity and are presently in discussions with various potential institutional investors as well as corporate partners in relation to potential partnering and licensing opportunities. These potential relationships would further enable the consolidated entity to continue their current business objectives.
·In the event that additional funding is not obtained, the consolidated entity may have to significantly reduce their expenditure on research and development programs and other costs.

Having carefully assessed the uncertainties relating to the likelihood of securing additional funding and the consolidated entity’s ability to effectively manage their expenditures, the directors believe that the consolidated entity will continue to operate as going concerns for the foreseeable future and therefore that it is appropriate to prepare the financial statements on a going concern basis.

Notwithstanding the above, there is significant uncertainty whether the consolidated entity can continue as going concerns. If the consolidated entity are unable to continue as going concerns they may be required to realize their assets and extinguish their liabilities other than in the normal course of business and at amounts different to those stated in the financial statements.

No adjustments have been made to the financial report relating to the recoverability and classification of the asset carrying amounts or the classification of liabilities that might be necessary should the consolidated entity not continue as going concerns.

Development Stage - Risks and uncertainties

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

1.BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

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

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

Significant Accounting Policies

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

The following significant accounting policies have been adopted in the preparation and presentation of the financial report:

1BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)report.

(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 its controlled entitiessubsidiaries as defined in Accounting Standard AASB 1024:127: Consolidated Accountsand Separate Financial Statements. 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 profitsprofits/losses arising within the consolidated entity are eliminated in full.

(b)
Cash and cash equivalentsIncome Tax

ForCurrent tax
Current tax is calculated by reference to the purposesamount of income taxes payable or recoverable in respect of the Statementtaxable profit or loss for the period. It is calculated using tax rates and tax laws that have been enacted or substantively enacted by reporting date. Current tax for current and prior periods is recognized as a liability (or asset) to the extent that it is unpaid (or refundable).

Deferred tax
Deferred tax is accounted for using the comprehensive balance sheet liability method in respect of Cash Flows, cash includes cashtemporary differences arising from differences between the carrying amount of assets and liabilities in the financial statements and the corresponding tax base of those items.

In principle, deferred tax liabilities are recognized for all taxable temporary differences. Deferred tax assets are recognized to the extent that it is probable that sufficient taxable amounts will be available against which deductible temporary differences or unused tax losses and tax offsets can be utilized. However, deferred tax assets and liabilities are not recognized if the temporary differences giving rise to them arise from the initial recognition of assets and liabilities (other than as a result of a business combination) which affects neither taxable income nor accounting profit or loss.

Deferred tax liabilities are recognized for taxable temporary differences arising on handinvestments in subsidiaries except where the consolidated entity is able to control the reversal of the temporary differences and it is probable that the temporary differences will not reverse in banksthe foreseeable future. Deferred tax assets arising from deductible temporary differences associated with these investments are only recognized to the extent that it is probable that there will be sufficient taxable profits against which to utilize the benefits of the temporary differences and money market investments readily convertiblethey are expected to cash.reverse in the foreseeable future.

PRANA BIOTECHNOLOGY LIMITED
(A Development Stage Enterprise)
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - in Australian dollars (unless otherwise noted)
1.BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period(s) when the asset and liability giving rise to them are realized or settled, based on tax rates (and tax laws) that have been enacted or substantively enacted by reporting date. The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow from the manner in which the consolidated entity expects, at the reporting date, to recover or settle the carrying amount of its assets and liabilities.

Deferred tax assets and liabilities are offset when they relate to income taxes levied by the same taxation authority and the Company/consolidated entity intends to settle its current tax assets and liabilities on a net basis.

Current and deferred tax for the period
Current and deferred tax is recognized as an expense or income in the statement of operations, except when it relates to items credited or debited directly to equity, in which case the deferred tax is also recognized directly in equity, or where it arises from the initial accounting for a business combination, in which case it is taken into account in the determination of goodwill.

The consolidated entity has significant unused tax losses and as such a significant deferred tax asset; however, the deferred tax asset has not been recognized, as it is not probable that future taxable profit will be available against which the unused losses and unused tax credits can be utilized, given the nature of the consolidated entity’s business (research and development) and its history of losses.

(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.

(d)
Property and equipment

Property and equipment is measured on the cost basis less accumulated depreciation and impairment and consists of laboratory equipment, computer equipment, furniture and fittings and leasehold improvements attributable to the Company’sPrana’s premises at Parkville, Victoria, Australia andAustralia. Cost includes expenditure that is recorded at cost. directly attributable to the acquisition of the item.

Depreciation
Depreciation is provided on a straight-linestraight line basis so as to write off the net cost or other revalued amount of each asset over theits expected useful life.

The following estimated useful lives, ofranging from three to 14 years.
years, are used in the calculation of depreciation:

Laboratory equipmentFurniture and fittings10%-33%5-33%
Computer equipment33%
Furniture and fittingsLaboratory equipment7.5%-33%
Leasehold improvements7.5%10-33%
 
(e)
Intangible assets and patents, research and development expense
Leasehold improvements are depreciated over the shorter of the lease term and useful life.

Until December 1999, costs associated with the acquisitionThe depreciation method, residual values and development of the consolidated entity’s core intellectual property were capitalized as intangible assets. After considering an independent valuation of the consolidated entity’s core intellectual propertyuseful lives are reviewed, and adjusted if appropriate, at December 1999, the 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.

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 financialeach annual reporting purposes.

Core intellectual property was 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 reviewed the carrying value of core intellectual property to ensure its carrying value did not exceed its recoverable amount.

(f)
Payables

Liabilities for trade creditors and other amounts are carried at cost, which is the fair value of the consideration to be paid in the future for goods and services received, whether or not billed to the consolidated entity.

Payables to related parties are carried at the principal amount.

(g)
Share capital

Ordinary share capital is recognized at the fair value of the consideration received by the consolidated entity, as determined by the directors.

(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 when 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.

1BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

(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.

(j)
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:

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

are charged against profits on a net basis in their respective categories.

The value of the options issued under the Employee and Consultants Option Plans described in Note 15(b) are not being charged as an expense when they have been issued to an employee or director.

(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.

(l)
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.

Interest and dividends

Interest and dividends are classified as expenses or as distributions of profit consistent with the Statements of Financial Position classification of the related debt or equity instruments or component parts of compound instruments.

(m)
Goods and services tax

Revenues, expenses and assets are recognized net of the amount of goods and services tax (GST), except:

i.Where the amount of GST incurred is not recoverable from the taxation authority, it is recognized as part of the cost of acquisition of an asset or as part of an item of expense; or
ii.
For receivables and payables which are recognized inclusive of GST.

The gross amount of GST recoverable from, or payable to, the taxation authority is included as part of receivables or payables.

Cash flows attributable to GST are included in the Statements of Cash Flows on a gross basis. The GST component of cash flows arising from investing and financing activities which is recoverable from, or payable to, the taxation authority is classified as operating cash flows.

(n)
Receivables

Trade receivables and other receivables are recorded at amounts due less any provision for doubtful debts.

(o)
Foreign currency

Foreign currency transactions
All foreign currency transactions during the financial year are brought to account using the exchange rate in effect at the date of the transaction. Accounts payable and receivable balances at reporting date are translated at the exchange rate in effect at that date. Exchange rate differences are recognized in net profit and loss in the period in which they arise.

Foreign operations
Financial statements of integrated foreign operations are translated at reporting date using the temporal method with exchange differences being taken to net profit or loss for the period.

Leased assetsAssets
Leased assets classified as finance leases are recognized as assets. The amount initially brought to account is the present value of minimum lease payments.

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 straight-line basis which reflectsover the lease term, except where another systematic basis is more representative of the time pattern in which economic benefits from the leased assetassets are consumed.

(s)(e)
Financial Instruments - Loans and Receivables
Trade receivables, loans, and other receivables are recorded at amortized cost less impairment.

(f)
Impairment of Assets
At each reporting date, the consolidated entity reviews the carrying amounts of its tangible and intangible assets to determine whether there is any indication that those assets have been impaired. If any such indication exists, the recoverable amount of the asset is estimated to determine the extent of the impairment loss (if any).

Where the asset does not generate cash flows that are independent from other assets, the consolidated entity estimates the recoverable amount of the cash-generating unit to which the asset belongs.

Intangible assets not yet available for use are tested for impairment annually and whenever there is an indication that the asset may be impaired.

Recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.

If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than its carrying amount, the carrying amount of the asset (or cash-generating unit) is reduced to its recoverable amount. An impairment loss is recognized in profit or loss immediately.

Where an impairment loss subsequently reverses, the carrying amount of the asset (or cash-generating unit) is increased to the revised estimate of its recoverable amount, but only to the extent that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset (or cash-generating unit) in prior years. A reversal of an impairment loss is recognized in profit or loss immediately.

(g)
Intangibles - Research and Development
Expenditure during the research phase of a project is recognized as an expense when incurred. Where no internally generated intangible assets can be recognized, development expenditure is recognized as an expense in the period as incurred. Development costs are capitalized if and only if, all of the following are demonstrated:
• the technical feasibility of completing the intangible asset so that it will be available for use or sale;
• the intention to complete the intangible asset and use or sell it;
• the ability to use or sell the intangible asset;
• how the intangible asset will generate probable future economic benefits;
• the availability of adequate technical, financial and other resources to complete the development and to use or sell the intangible asset; and
• the ability to measure reliably the expenditure attributable to the intangible asset during its development.

Internally-generated intangible assets (capitalized development costs,) are stated at cost less accumulated amortization and impairment, and are amortized on a straight-line basis over their useful lives over a maximum of five years.

At June 30, 2006 and 2005, Prana had no capitalized research and development costs.

Foreign Currency Transactions and Balances
Foreign currency transactions
All foreign currency transactions during the financial year are brought to account using the exchange rate in effect at the date of the transaction. Foreign currency monetary items at reporting date are translated at the exchange rate existing at reporting date. Non-monetary assets and liabilities carried at fair value that are denominated in foreign currencies are translated at the rates prevailing at the date when the fair value was determined.

Exchange differences are recognized in profit or loss in the period in which they arise except for exchange differences on monetary items receivable from or payable to a foreign operation for which settlement is neither planned or likely to occur, which form part of the net investment in a foreign operation, are recognized in the foreign currency translation reserve and recognized in profit or loss on disposal of the net investment.

Foreign operations
On consolidation, the assets and liabilities of the consolidated entity’s overseas operations are translated at exchange rates prevailing at the reporting date. Income and expense items are translated at the average exchange rates for the period unless exchange rates fluctuate significantly. Exchange differences arising, if any, are recognized in the foreign currency translation reserve, and recognized in profit or loss on disposal of the foreign operations.

(i)
Employee Benefits
Provision is made for the consolidated entity's liability for employee benefits arising from services rendered by employees to reporting date. Employee benefits that are expected to be settled within one year have been measured at the amounts expected to be paid when the liability is settled, plus related on-costs. Employee benefits payable later than one year have been measured at the present value of the estimated future cash outflows to be made for those benefits.

(j)
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.

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 virtually certain that recovery will be received and the amount of the receivable can be measured reliably.

(t)(k)
Cash and cash equivalents
Cash and cash equivalents includes cash on hand, deposits held at call with banks, other short-term highly liquid investments with original maturities of three months or less.

(l)
Revenue
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. Revenue is made up of interest income which is recognized as earned when collectibility is reasonably assured.

Trade payables and other payables are recognized when the consolidated entity becomes obliged to make future payments resulting from the purchase of goods or services.

(p)
Share-based payments
Equity-settled share-based payments granted after November 7, 2002 that were unvested as of January 1, 2005 are measured at fair value at the date of grant. Fair value is measured by use of the Black- Scholes model (for options without market conditions) or the Barrier Pricing model (for options with market conditions). The expected life used in the model has been adjusted, based on management’s best estimate, for the effects of non-transferability, exercise restrictions, and behavioral considerations. The date used to value share-based payments for non-employees may be different to the grant date used to value employee share-based payments where service conditions apply.

The fair value of the equity-settled share-based payments is expensed on a straight-line basis over the vesting period for each tranche of equity, based on the consolidated entity’s estimate of shares that will eventually vest.

(q)
Loss per share
Basic loss per share is determined by dividing the net loss after income tax expense by the weighted average number of ordinary shares outstanding during the financial 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.

(r)
Goods and Services Tax (GST)
Revenues, expenses and assets are recognized net of the amount of GST, except where the amount of GST incurred is not recoverable from the taxation authority. In these circumstances the GST is recognized as part of the cost of acquisition of the asset or as part of an item of expense. Receivables and payables in the balance sheet are shown inclusive of GST.

The net amount of GST recoverable from, or payable to, the taxation authority is included as part of receivables or payables.

Cash flows are included in the statement of cash flows on a gross basis. The GST component of cash flows arising from investing and financing activities which is recoverable from, or payable to, the taxation authority is classified as operating cash flows.

The following Pro Forma Consolidated Statementsentity's balance sheet and statement 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 outlinedoperations is set out in the following pro forma financial statements.tables and notes that accompany the tables.

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.

1BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)
(t) Adoption of Australian EquivalentsExplanatory Notes to Internationalthe Financial Reporting Standards (Unaudited) (continued)Statements

The following explanatory notes relate to the unaudited pro forma consolidated financial statements above and describe the differences between the accounting policespolicies under A-IFRS and the currentprevious treatment of those items under Australian Generally Accepted Accounting Principles (“A-GAAP”).the Superseded Policies.

A.(a) Share-based Payments
Under A-GAAP,the Superseded Policies, the consolidated entity doesdid not recognize an expense for share-based compensation granted to employees orand directors. Under A-IFRS, the fair value of share options issuedgranted to employees and directors is determined at the grant date and expensed over the expected vesting period of the options. As permitted under A-IFRS first time adoption, the consolidated entity willdid not retrospectively recognize share-based payments that havewere granted before November 7, 2002 and share based payments granted after November 7, 2002 that vested before January 1, 2005.

For the financial year ended June 30, 2005, under A-IFRS contributed equity will increasereserves increased by A$1,704,734 and an additional employee benefitspersonnel expense of the same amount will bewas recognized in profit and lossthe statement of operations in relation to the options issued during the year.

B.Under A-IFRS, a share based payment reserve arises on the grant of share options and warrants. Previously these amounts were allocated to issued capital. At June 30, 2005, a further A$743,262 previously included in issued capital was moved into the share based payments reserve under A-IFRS.

1.BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)
(b) Intangible Assets
Under A-GAAP,the Superseded Policies, the consolidated entity revalued the core intellectual propertyacquired research and development costs to fair value in December 1999. Under A-IFRS the revaluation is permissible only if there is an active market for the asset. As a consequence, upon transition to A-IFRS aton July 1, 2004, intangible assets will decreasedecreased by A$10,208,582 (net of accumulated amortization) 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.4,453,360.

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 decreasedecreased by A$410,321 (net of accumulated amortization) with a corresponding increase in accumulated deficit at that date.losses.

As a result of the above transition adjustments, the carrying value of the intangible assets at July 1, July 2004 was A$AS$869,440.

Under AASB 1 Prana has not elected to take the option to fair value the intangible assets at July 1, 2004.

The impact of the above transition adjustmentadjustments to A-IFRS for the financial year ended June 30, 2005, is that the amortization expense will decreasedecreased by A$1,016,804 and the impairment of intangible assets will decrease by A$9,602,099.9,602,099, which reverses a portion of the impairment recorded under Superseded Policies given that a portion of the asset was already derecognized under A-IFRS. In addition, the asset revaluation reserve as at June 30, 2005 will decreasedecreased by A$14,661,942.

C.(c) Financial Instruments
The directors have elected not to apply the first-time adoption exemption available to Pranathe consolidated entity to defer the date of transition of AASB 132:132 Financial Instruments: Disclosure and Presentationand AASB 139:139 Financial Instruments: Recognition and Measurement'Measurement to July 1,2005. This hasstandard had nil effect on the financial statements of the consolidated financial statements.entity.

(e) Revenue
Under the Superseded Policies, the consolidated entity recorded as revenue all of Contributed Equity as at July 1, 2004
There were no adjustments to the Contributed Equityconsolidated entity’s inflows. Under A-IFRS, the consolidated entity’s revenue represents interest income, with the remaining inflows of the consolidated entity at July 1,2004. Contributed Equity under A-GAAP(being government grants and corporate partner revenues) classified as other income. At June 30, 2005, this reduced revenue by A$1,760,978 and increased other income by the same amount.

(f) Effect of A-IFRS on the Cash Flow Statement
There are no material differences between the Cash Flow Statement presented under A-IFRS at July 1,2004 was A$49,505,493.and the Cash Flow Statement presented under the Superseded Policies for the year ended June 30, 2005.

Share-based compensation

As described in Note 1(s), Prana adopted AASB 2: OptionsShare-Based Payment. In accordance with the transitional provisions of AASB 2, the Standard has been applied retrospectively to all share-based payments granted / issued to consultants for services renderedafter November 7, 2002 and that were not yet vested as of January 1, 2005.

As disclosed in Note 11(c), the Company issued 600,000, 1,444,500 and 405,000 share options to outside consultants during the years endedThrough June 30, 2005, 2004 and 2003, respectively. Under A-GAAP, the Company recognized compensation expense based on the directors’ valuation of the options issued during the year ended June 30, 2005. No compensation cost was recognized in respect of the options issued by the Company during the years ended June 30, 2004 and 2003 under A-GAAP. Under US GAAP, the options issued to the outside consultants arePrana accounted for options granted to employees and directors under Statements of Financial Accounting Standards (“SFAS”) No. 123: Accounting for Stock Based Compensation (“SFAS 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”). 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,U.S. GAAP using the Black-Scholes model with the following weighted average assumptions:
·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 directors and employees during the years ended June 30, 2005, 2004 and 2003, respectively. Under A-GAAP, no compensation cost has been recognized 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 employeesintrinsic value method in accordance with Accounting Principles Board (“APB”) Opinion No. 25: Accounting for Stock Issued to Employees (“APB 25”) and related interpretations (“APB 25”).to measure employee stock compensation. Under APB 25, compensation cost isexpense was recognized to the extent that the quoted market price of the stock exceedsexceeded the exercise price of the options at the measurement date, and iswas charged to earnings ratably over the vesting period. For options that vest upon the achievement of a target stock price, compensation expense iswas recognized when the target is achieved.

Under A-GAAP, noSFAS 123 and EITF 96-18, compensation cost was recognized in respect of the share options issued by the Company. Under US GAAP, the options issued to the underwriters were accounted for under SFAS 123. Accordingly, the consolidated entity has calculated compensation cost based on the estimated fair value of the options measured on March 1, 2003. Because the options are exercisable only on the date of grant, the Company estimatedservices were completed by the fair value of the options based on the intrinsic value of the options.respective consultants.

SharesThrough June 30, 2005, Prana also accounted for shares issued to consultants and directors for services rendered

As disclosedunder U.S. GAAP in Note 11(b), the Company issued 228,215, 1,119,225 and 146,969 shares to outside consultants in consideration for services rendered to the Company during the years ended June 30, 2005, 2004 and 2003, respectively. The Company also issued 249,999 shares to directors in consideration for services rendered to the Company during each of the years ended June 30, 2005 and 2004. Under A-GAAP, the consolidated entity recognized compensation expense based on the directors’ valuation of the services rendered or shares issued. Under US GAAP, the shares issued to the outside consultants and directors are accounted for underaccordance with SFAS 123 and EITF 96-18. Accordingly, compensation expense iscost was based on the quoted market price of the shares measured on the date the services were completed.

Effective July 1, 2005, for U.S. GAAP purposes Prana adopted SFAS No. 123(R), Share-Based Payment (“SFAS 123R”) which replaces SFAS 123 and supersedes APB 25. Under the modified prospective method of SFAS 123R, Prana applies SFAS 123R for equity-based compensation awards (or portion thereof): (i) granted on or after July 1, 2005; (ii) modified on or after July 1, 2005; and (iii) not yet vested as of July 1, 2005. Such equity-based compensation awards are measured based on the fair value using the Black-Scholes model (for options without market conditions) or Barrier Pricing model (for options with market conditions). The resulting difference between the A-GAAP compensation expense and the US GAAP compensation expense is recognized as an expense in the accompanying reconciliation.

b.
Intangible assets - Core intellectual property

Under A-GAAP, the consolidated entity capitalised costs associated with the acquisition and developmentstatement of core intellectual property until December 1999. Such costs were amortized on a straight-line basisoperations over the estimated useful life of 15 years. In December 1999, the directors revalued the intangible assets upwards by A$14,661,942 and recorded the revaluation in the asset revaluation reserve in equity. The increased asset value resulted in additional amortisation forrequisite service period. Prior 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.

Under US GAAP, costs associated with the acquisition of core intellectual property are capitalised while costs associated with the development of core intellectual property are expensed as incurred. Upward revaluations of intangible assets arehave 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.been restated.

As a result of the cancellation of a clinical studyadopting SFAS 123R on July 1, 2005, Prana’s U.S. GAAP loss before income taxes and net loss for the compound PBT-1year ended June 30, 2006 was A$76,469 higher than if Prana had continued to account for share-based compensation to employees and directors under APB 25. The impact of adopting SFAS 123R did not have a material impact on basic and diluted loss per share, cash flows from operating activities and cash flows from financing activities for the year ended June 30, 2006.

Total U.S. GAAP share-based compensation costs charged to the statement of operations was A$1,046,159 and A$444,075 for the years ended June 30, 2006 and 2005, respectively. No income tax benefits were recognized and no compensation cost was capitalized as part of property and equipment during the periods presented.
The retrospective transition provision of AASB 2 and the modified prospective transition provision of SFAS 123R give rise to GAAP differences in April 2005 dueshare−based compensation for the ended June 30, 2005. There are no U.S. GAAP reconciling items attributable to toxicity issues,share−based compensation for the consolidated entity reviewedyear ended June 30, 2006 as the carrying valueimpact on compensation cost resulting from differences in the standards, such as the determination of the core intellectual property and resolvedmeasurement date for share−based payments made to impair the value to A$nil as of June 30, 2005 based on estimated future discounted cash flows.

Intangible assets - Capitalised patent costs

Under A-GAAP, allA-IFRS, patent costs associated withare recognized at cost less accumulated amortization and impairment, provided the acquisition and development of patents incurred subsequent tocosts meet the December 1999 revaluation of core intellectual propertycriteria for recognition as an intangible asset (see paragraph (b) above)Note 2(g)). Patent costs that do not meet the criteria for recognition as an intangible asset are expensed as incurred. At June 30, 2006 and 2005, Prana had no capitalized patent costs under A-IFRS.

For USU.S. GAAP purposes, up until December 31, 2004, all costs associated with the acquisition of patents, legal costs incurred in connection with successful patent defencesdefenses and costs associated with successful patent applications deemed to be recoverable from the future development of products were capitalisedcapitalized and amortized on a straight-linestraight−line basis over the estimated useful life of 15 years. Such capitalisedcapitalized 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 were expensed as incurred. Effective January 1, 2005, the CompanyPrana changed its USU.S. GAAP accounting policy and expenses all patent costs as incurred.

As a result of the cancellation of a clinical study for the PBT−1 compound PBT-1 in April 2005 due to toxicity issues, the consolidated entity reviewed the carrying value of the USU.S. GAAP capitalisedcapitalized patent costs and resolved to impair the capitalisedcapitalized costs to the fair value of A$nil based on estimated future discounted cash flows. The resulting impairment expense has been recognized

For the year ended June 30, 2006, there are no GAAP differences in respect to intangible assets. In the accompanying reconciliation.future, GAAP differences may arise to the extent that development costs meet the criteria for capitalization under A-IFRS (as development costs are expensed as incurred under U.S. GAAP).

d.c.
Deferred tax effect of US GAAP adjustments

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

Statement of cash flows

The presentation of the Statements of Cash Flows in accordance with A-GAAP differs from that required in accordance with SFAS No. 95: Statement of Cash Flows (“SFAS 95”) under US GAAP. Under A-GAAP, cash held in term deposits with original maturities of less than one year is classified as cash. Under US GAAP, term deposits with original maturities greater than 90 days do not qualify as cash or cash equivalents; rather, such term deposits are classified as current investments. Accordingly, the net change in term deposits with original maturities greater than 90 days is classified as a component of cash flows from investing activities for US GAAP purposes.

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, 20042006 and 20032005 is A$0.44,0.18 and 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 5.3% for 2006 and 5.2% for 2005, 4.9% for 2004 and 4.3% for 2003;2005;
 ·no dividends;
 ·expected volatility of 117.2% for 2006 and 65.7% for 2005, 74.3% for 2004 and 82.0% for 2003;2005; and
 ·expected life of four years for 2006 and five years for 2005 and two years for 2004 and 2003.2005.

Risk−free interest rate - This is the government bond rate (having a term that most closely resembles the expected life of the option) in effect at the grant date. The Australian government bond rate has been used for options which convert to full paid ordinary shares and the U.S. government bond rate has been used for options which convert to ADRs.

Dividend yield - Prana has never declared or paid dividends on its common stock and does not anticipate paying any dividends in the foreseeable future.

Expected volatility - Prana estimates expected volatility based on historical volatility over the estimated life of the option and other factors.

Expected life - This is the period of time that the options granted are expected to remain outstanding. This estimate is based primarily on historical trend of option holders to exercise their option near the date of expiry. As a result the expected life is considered to equal the period from grant date to expiry date.

The following table summarizes the activity of share options issued to directors under the 2004 ADS Option Plan (adopted on November 17, 2004) during the yearyears ended June 30, 2006 and 2005.

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.A-IFRS.

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)years.

Recently issued but not yet adopted accounting pronouncements

In December 2004,May 2005, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 123 (revised 2004):154: 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.

In July 2006, the FASB issued Interpretation No. 48, Accounting for Uncertainty in Income Taxes” (“FIN 48”) as an interpretation of SFAS 109. This Interpretation clarifies the accounting for uncertainty in income taxes recognized by prescribing a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. This Interpretation also provides guidance on de-recognition of tax benefits previously recognized and additional disclosures for unrecognized tax benefits, interest and penalties. The evaluation of a tax position in accordance with this Interpretation begins with a determination as to whether it is more likely than not that a tax position will be sustained upon examination based on the technical merits of the position. A tax position that meets the more-likely-than-not recognition threshold is then measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement for recognition in the financial statements. FIN 48 is effective no later than fiscal years beginning after December 15, 2006, and is required to be adopted by the consolidated entity on July 1, 2007. The consolidated entity is currently assessing the impact of the adoption of FIN 48.

26.RECONCILIATION TO US GAAP (continued)

In September 2006, the Securities and Exchange Commission (the “SEC”) issued Staff Accounting Bulletin No. 108, Considering the Effects of Prior Year Misstatements when Qualifying Misstatements in Current Year Financial Statements (“SAB 108”) which provides interpretive guidance on the consideration of the effects of prior year misstatements in quantifying current year misstatements for the purpose of a materiality assessment. SAB 108 is effective for companies with fiscal years ending after November 15, 2006 and is required to be adopted by the Company in fiscal 2007. However, early application is encouraged in any report for an interim period of the first fiscal year ending after November 15, 2006, filed after the publication of this guidance. The consolidated entity is currently assessing the impact of the adoption of SAB 108.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements (“SFAS 157”).. SFAS 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. This Statement applies under other accounting pronouncements that require or permit fair value measurements, the FASB having previously concluded in those accounting pronouncements that fair value is the relevant measurement attribute. Accordingly, this Statement does not require any new fair value measurements. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. This Statement is required to be adopted by the consolidated entity on July 1, 2008. The consolidated entity is currently assessing the impact of the adoption of this Statement.
