Exchange Rates  In this Annual Report, unless otherwise specified, all dollar amounts are expressed in Canadian Dollars (CDN$).  The Government of Canada permits a floating exchange rate to determine the value of the Canadian Dollar against the U.S. Dollar (US$). Table No. 4 sets forth the exchange rates for the Canadian Dollar at the end of five most recent fiscal years ended June 30, 2007, the average rates for the period and the range of high and low rates for the period.  The data for each month during the most recent six months is also provided. For purposes of this table, the rate of exchange means the noon buying rate in New York City for cable transfers in foreign currencies as certified for customs purposes by the Federal Reserve Bank of New York. The table sets forth the number of US Dollars required under that formula to buy one Canadian Dollar.   For example, where the number 0.8704 is quoted in the upper left hand number in the table, it means that it took on average in February 2006, 87.04 cents US to purchase one Canadian dollar.  For all periods presented, the Canadian dollar has been worth less than one US dollar.    Alda Pharmaceuticals Corp. 2007 20F/A Page 4

The Company has been operating only since November, 2003 and has operating losses of $562,090, $378,301380,026, and $796,301798,028 in the years ended June 30, 2007, 2006 and 2005, respectively. This limited operating history and the varying amount of funds spent on activities such as patenting, trademark protection and product development and testing



leads the Company to believe that period-to-period comparisons of its operating results may not be meaningful and that the results for any particular period should not be relied upon as an indication of future performance. For example, over the last three fiscal years, the revenues generated from the sale of T36® Disinfectant have been relatively consistent. In 2005 revenues were $239,271, decreased by 6.5% in 2006 to $223,586, most likely due to the timing of customer orders. Revenues increased again in 2007 by 15% to $256,243, a level that was 7% higher than 2005. likely die to the timing of customer orders and the introduction of the new T36® Hand Sanitizer. There is more variability in operating expenses which decreased from $642,224 for 2005 to $498,616 in 2006 and increased again to $662,958 in 2007. These decline in costs that were observed in 2006 were due to reductions in consulting fees paid to executives of the Company and to outside consultants, lower investor relations costs and a decline wages and benefits. An impairment loss of $245,000 on intangible assets was claimed during the fiscal year of 2005 due to the revenues of the Company not matching the expectations that were established during the valuation for the  Alda Pharmaceuticals Corp. 2007 20F/A Page 6 
---------------------------------------------------------------------------------------------------------------------------------------------------------    Qualifying Transaction. In connection with the settlement of legal disputes, the Company recognized a net gain of $10,545 and $37,383 in fiscal years 2007 and 2006, respectively, with no such gain in 2005. In the future, the Company is intending to invest varying amounts in continued intellectual property protection, product development, product testing of therapeutic products and clinical trials. All of these discretionary activities depend on the availability of external funds. Since the Company cannot depend on being able to raise funds as needed for its planned activities, the expenditures will match the availability of external funds. Therefore, the levels of these discretionary expenditures are not predictable. Also, the Company has been working on new products that may be introduced to the market but the timing of such product introductions is never certain. As a result, the Company cannot predict its expenditures, revenues or losses with any certainty. However, since an ambitious program of product testing and registrations are planned, it is certain that the any funds that are raised will be invested in these activities and that losses will be incurred for the foreseeable future the magnitude of these losses cannot be perdicte

d. This conclusion is based on the fact that at the beginning of operations, expenses were relatively high due to the costs associated with starting up a new venture, such as the costs of manufacturing product, warehousing, preparing new marketing materials and securing facilities and equipment. After these start-up costs had been absorbed, the cost of goods became stabilized. However, at the end of the 2004 and 2005 fiscal years, there was a significant write-down of the assets purchased in the Qualifying Transaction due to revenues not meeting expectations. In addition, there have been extraordinary legal costs associated with a legal action, described elsewhere, commenced by a competitor, gains on a legal settlement over a trademark dispute and an action launched by the Company against a competitor that resulted in a settlement. These extraordinary events make predictions of future periods difficult. The Company has no significant source of operating cash flow and failure to generate revenues in the future could cause the Company to go out of business. Based upon current plans to introduce T36® Disinfectant into additional markets in Canada and internationally, pursue the patent applications and regulatory approvals for the T36®technology, develop new products, maintain the Companys public listing on the TSX-TSXVenture Exchange and secure a listing in the US, the Company expects to incur operating losses in future periods. These loses will occur because there are continuing expenses associated with the marketing and production of the Companys products, research and development, intellectual property protection, registration of products with regulatory bodies, legal and accounting fees, the maintenance of its public listing and other expenses associated with running an operating business. The Company has a burn rate of approximately $45,000 per month. At this burn rate, the cash on hand of $356,127 as of June 30, 2007 will last approximately eight months and further fund raising will be required to continue operations. Also, the Company may not be successful in generating revenues in the future. Failure to generate revenues could cause the Company to go out of business. If the Company raises further funds through equity issuances, the price of its securities could decrease due to the dilution caused by the sale of additional shares. Additional funds raised by the Company through the issuance of equity or convertible debt securities will cause the Companys current shareholders to experience dilution and possibly lower the trading price of its shares.  Such securities may grant rights, preferences or privileges senior to those of the Companys common shareholders. The Company is not profitable and will not be profitable for the foreseeable future under its current development plan. The Company plans to issue further equity to raise funds as necessary to continue operations and fund its program of research and development, patent protection and regulatory approvals. As a result, an indeterminate amount of dilution of the Companys capital stock will occur. The Company has issued only 32,192,404 shares out of its authorized capital of an unlimited number of common shares, which could be dilutive and negatively affect the share price. Having an unlimited number of authorized but unissued common shares could allow the Companys Directors and Officers to issue a large number of shares without shareholder approval, leading to significant dilution of current shareholders and possible lowering of the share price. The Company could enter into debt obligations and not have the funds to repay these obligations. The Company does not have any contractual restrictions on its ability to incur debt and, accordingly, the Company could incur significant amounts of indebtedness to finance its operations. Any such indebtedness could contain covenants, which would restrict the Companys operations. The Company might not be able to repay indebtedness.  The Company does not plan on entering into any debt obligations in the next twelve months. The Company has a history of generating limited revenues and the continuing failure to generate further revenues could cause the Company to cease operations.  Alda Pharmaceuticals Corp. 2007 20F/A Page 7 
---------------------------------------------------------------------------------------------------------------------------------------------------------    The Company has no history of pre-tax profit and in the previous three years has had annual revenues for each of the years ended June 30 of $256,243 in 2007 $223,586 in 2006 and $239,271 in 2005. The Company sustained operating losses for each of the fiscal years ended June 30, 2007, 2006 and 2005 of $562,090, $380,026, and$798,028$562,090, $378,301 and $796,301

, respectively. The Company has sustained accumulated operating losses in its last audited year of operation in fiscal 2007 of $2,603,791. The continued operation of the Company will be dependent upon its ability to generate operating revenues and to procure additional financing. The Company may not be successful in generating revenues or raising capital in the future. Failure to generate revenues or raise capital could cause the Company to cease operations.  The auditors report to the shareholders, dated October 17, 2007, is expressed in accordance with Canadian reporting standards, which do not require a reference to conditions and events that cast substantial doubt on the Company's ability to continue as a going concern when these are adequately disclosed in the financial statements. In the United States, reporting standards for auditors require the addition of an explanatory paragraph when the financial statements are affected by conditions and events that cast substantial doubt on the Company's ability to continue as a going concern. Had the Companys financial statements been audited by US auditors, the Company may have received a going concern qualification. A going concern qualification, or the existence of a basis for such a qualification, could negatively affect the Companys ability to raise capital. As the Company is a Canadian company, it may be difficult for U.S. shareholders of the Company to effect service on the Company or to realize on judgments obtained in the United States. The Company is a Canadian corporation. A majority of its directors and officers are residents of Canada and a significant part of its assets are, or will be, located outside of the United States. As a result, it may be difficult for shareholders resident in the United States to effect service within the United States upon the Company, directors, officers or experts who are not residents of the United States, or to realize in the United States judgments of courts of the United States predicated upon civil liability of any of the Company, directors or officers under the United States federal securities laws. If a judgment is obtained in the U.S. courts based on civil liability provisions of the U.S. federal securities laws against the Company or its directors or officers, it will be difficult to enforce the judgment in the Canadian courts against the Company and any of the Companys non-U.S. resident executive officers or directors. Accordingly, United States shareholders may be forced to bring actions against the Company and its respective directors and officers under Canadian law and in Canadian courts in order to enforce any claims that they may have against the Company or its directors and officers. Nevertheless, it may be difficult for United States shareholders to bring an original action in the Canadian courts to enforce liabilities based on the U.S. federal securities laws against the Company and any of the Companys non-U.S. resident executive officers or directors. The Companys future performance is dependent on key personnel. The loss of the services of any of the Companys executives or Board of Directors could have a material adverse effect on the Company. The Companys performance is substantially dependent on the performance and continued efforts of the Companys executives and its Board of Directors. Dr. Terrance G. Owen is the President, Chief Executive Officer and a Director. Peter Chen is the Secretary, Chief Financial Office and a Director. Dr. Linda Allison, Dr. Ronald Zokol, Dr. William F. McCoy and Eugene Hodgson are independent Directors. Dr. Allison, Mr. Chen and Mr. Hodgson are members of the Audit Committee. The loss of the services of any of the Companys executives or Board of Directors could have a material adverse effect on the Companys business, results of operations and financial condition. There is no assurance that key personnel can be replaced with people with similar qualifications within a reasonable period of time. The Company currently does not carry any key person insurance on any of the executives or members of the board of directors. There are no contracts in place with any of the employees, officers or directors of the Company. The Company has not declared any dividends since its inception in 2000 and has no present intention of paying any cash dividends on its common shares in the foreseeable future. The Company has not declared any dividends since its inception in 2000, and has no present intention of paying any cash dividends on its common shares in the foreseeable future. The payment by the Company of dividends, if any, in the future, rests in the discretion of the Company's Board of Directors and will depend, among other things, upon the Company's earnings, its capital requirements and financial condition, as well as other relevant factors. The Companys future performance is dependent on key collaborators and a loss of any collaborators could have a material adverse effect on the Company by reducing or eliminating the ability of the Company to manufacture or sell its products.  Alda Pharmaceuticals Corp. 2007 20F/A Page 8 
---------------------------------------------------------------------------------------------------------------------------------------------------------    The Company is dependent on Norwood Packaging Ltd. to manufacture its products to a standard that is accepted by Health Canada



(Exhibit 4.b..). Although other manufacturers have been identified, they do not have the same familiarity as Norwood with the manufacturing of the Companys products. If the Company had to switch manufacturers there would be a start-up period in which sales would be lost and revenues would drop. TheAnAgreementagreement



with Fuzhou Xinmei Biotech Co. Ltd. (Fuzhou), which allowed manufacturing and marketing in Fujian province in China



(Exhibit 4.c.)



 has been transferred to He-Yi She Ye Limited (He-Yi) and expanded to cover marketing in all of China



(Exhibit 4.g.)

.. The relationship with He-Yi is important because registration and manufacturing of T36®Disinfectant in China depends on the successful completion of the required applications by He-Yi and acceptance of the registrations by the Chinese government agencies. At this time, the Company has no other agent working on its behalf in China. If He-Yi were to fail or go out of business, the Company would have to find another agent to represent its interests in China. This would delay the registrations in China and lead to reduced revenue expectations. The loss of  the services of Phigenics, LLC to assist with US product registrations would necessitate finding another collaborator to assist with registrations of the Companys products with the Environmental Protection Agency (EPA) of the US  and with the marketing of the Companys products to the customer base served by Phigenics.

The same is true of Linns Corporation Sdn Bhd. If the arrangement with Linns was terminated, another agent would have to be found for South East Asia. There is no assurance that the patent applications filed for theT36® technology or for other products will be approved, and failure to obtain such approvals could leave the Company with no protection for its intellectual property and reduced sales. Patent protection of the T36® technology is very important to the Companys current and future products because the T36® Disinfectant technology is the basis for its products. Although patents have been allowed in the United States, and in China, there is also no assurance that future patent applications will be successful.  A lack of patent protection would significantly alter the competitive environment and possibly allow competitors to infringe on the technology of the Companys business. Reduced revenues and lack of future products could result from such infringement. There is no assurance that the Company will be able to secure the funds needed for future development, and failure to secure such funds could lead to a lack of opportunities for growth. Many of the Companys products require laboratory testing that could cost as much as $100,000 per product or more to establish toxicity, efficacy and analytical methods. This testing is required in order to obtain required regulatory approvals from Health Canada and the EPA in the US.  A lack of funds would impair the ability of the Company to complete such tests.  A lack of funds would also impair the Companys ability to establish marketing and sales plans once the products have been approved for sale.  If adequate financing is not available when required, the Company may be required to delay, scale back or eliminate various activities and may be unable to continue in operation.  The Company may seek such additional financing through debt or equity offerings, but there can be no assurance that such financing will be available on terms acceptable to the Company or at all.  Any equity offering will result in dilution to the ownership interests of the Companys shareholders and may result in dilution to the value of such interests. There is no assurance that research and development being conducted by the Company to create new products will be successful. The Company is conducting research and development on new products, but the outcomes of research and development are never certain. For example, there is no assurance that any new products will be developed or that any new products that do result will have a competitive advantage or market acceptance, will not be superseded by the new products of competitors, will not infringe on the patents of other companies or that other companies will not develop products that infringe on patents obtained by the Company for its new products. The Company has completed the formulations for new products but still needs to conduct the toxicity and efficacy tests and establish the analytical methods required to obtain regulatory approvals from Health Canada and the EPA and FDA in the US. The Company and the Companys products have limited brand awareness which limits the ability of the Company to gain credibility from prospective customers and to sell its products into new markets. Market knowledge of the Companys name is limited. The Company will need to devote considerable resources to educate new markets about the products the Company offers.  In establishing new markets, the Company will be competing with companies that are potentially already entrenched in such markets or may be better funded than the Company. The ability of the Company to raise brand awareness will depend on its ability to raise the money required to undertake such an intensive marketing effort. As noted elsewhere, there is no assurance that the Company can raise funds required for such an investment in marketing.  Alda Pharmaceuticals Corp. 2007 20F/A Page 9 
---------------------------------------------------------------------------------------------------------------------------------------------------------     The Company has limited sales and marketing experience and can provide no assurance that the Company can keep its current customers or gain new ones. The Company has limited experience in marketing and selling its products.  The Company had two sales and marketing people until February 2, 2007, one with just over two years of experience with the Company and no prior sales experience, and the other with three years experience with the Company and no prior sales experience in pharmaceutical or disinfectant products. With the departure of the more experienced sales and marketing person, the Company has one person in sales and marketing. The Company will have to expend substantial funds to promote and develop its products. The Companys success in this regard will depend on the quality of its products and its ability to develop and implement an effective sales and marketing strategy. Current plans call for the expenditure of $ 235,000 over the next 18 months for marketing activities.  Failure to achieve these objectives will have a material adverse effect on the Company and on its results of operations and financial condition. Conflicts of interest may exist for Directors and Officers which may inhibit their ability to act in the best interests of the Company and its shareholders leading to possible impairment of the Companys ability to achieve its business objectives. The directors and officers of the Company will not be devoting all of their time to the affairs of the Company. The directors and officers of the Company are directors and officers of other companies. The directors and officers of the Company will be required by law to act in the best interests of the Company.  They will have the same obligations to the other companies in respect of which they act as directors and officers.  Discharge by the directors and officers of their obligations to the Company may result in a breach of their obligations to the other companies and, in certain circumstances, this could expose the Company to liability to those companies.  Similarly, discharge by the directors and officers of their obligations to the other companies could result in a breach of their obligation to act in the best interests of the Company.  Such conflicting legal obligations may expose the Company to liability to others and impair its ability to achieve its business objectives. Terrance Owen has been the Secretary of Bi-optic Ventures Inc., a company listed on the TSX-TSX



Venture Exchange, since September, 2002 and a Director of this same company since September, 2006. As a non-management Officer and Director of Bi-Optic Ventures Inc., Terrance Owen spends approximately eightfour



hours per month on the business of Bi-Optic Ventures Inc. since Bi-Optics is operationally inactive while seeking acquisition prospects.



Terrance Owen controls a company, Duft Enterprises Corp., that owns the building in which the Company is located and the Company pays rent to Duft Enterprises Corp. Peter Chen is not a Director or Officer of any other company



nor has Mr. Chen spent any time on other companies or on financial consulting for other companies since the Company completed the Qualifying Transaction in November, 2003. Neither Peter Chen nor Terrance Owen is a Director or Officer of any companies that compete with or provide services that are similar to those of the Company. Management of the Company can, through their stock ownership in the Company, influence all matters requiring approval by the Companys shareholders. Management of the Company as at June 30, 2007, directly



own collectively 1,599,5001,587,500



shares, which was 4.974.93% of the Company's issued and outstanding common shares at that date. These shareholders, if acting together, will be able to significantly influence all matters requiring approval by the Company's shareholders, including the election of directors and the approval of mergers or other business combination transactions. Management may not make decisions that will maximize shareholder value and may make decisions that will contribute to or cause the entrenchment of management. The value and transferability of the Company shares may be adversely impacted by the limited trading market for the Companys common shares. No assurance can be given that a market for the Companys common shares will be quoted on an exchange in the U.S. or on the NASD's Over the Counter Bulletin Board. The Companys common shares may be subject to illiquidity and investors may not be able to sell their shares in a timely manner. The value and transferability of the Company shares may be adversely impacted by the penny stock rules. The sale or transfer of the Company common shares by shareholders in the United States may be subject to the so-called "penny stock rules." Under Rule 15g-9 of the Exchange Act, a broker or dealer may not sell a "penny stock" (as defined in Rule 3a51-1) or effect the purchase of a penny stock by any person unless:  Alda Pharmaceuticals Corp. 2007 20F/A Page 10 
---------------------------------------------------------------------------------------------------------------------------------------------------------    (a)   Such sale or purchase is exempt from Rule 15g-9; (b)   Prior to the transaction the broker or dealer has (1) approved the person's account for transaction in penny stocks in accordance with Rule 15g-9, and (2) received from the person a written agreement to the transaction setting forth the identity and quantity of the penny stock to be purchased; and (c)   The purchaser has been provided an appropriate disclosure statement as to penny stock investment. The SEC adopted regulations generally define a penny stock to be any equity security other than a security excluded from such definition by Rule 3a51-1. Such exemptions include, but are not limited to (1) an equity security issued by an issuer that has (i) net tangible assets of at least $2,000,000, if such issuer has been in continuous operations for at least three years, (ii) net tangible assets of at least $5,000,000, if such issuer has been in continuous operation for less than three years, or (iii) average revenue of at least $6,000,000 for the preceding three years; (2) except for purposes of Section 7(b) of the Exchange Act and Rule 419, any security that has a price of $5.00 or more; and (3) a security that is authorized or approved for authorization upon notice of issuance for quotation on the NASDAQ Stock Market, Inc.'s Automated Quotation System. It is likely that the Companys common shares, assuming a market were to develop in the US, will be subject to the regulations on penny stocks. Consequently, the market liquidity for the common shares may be adversely affected by such regulations limiting the ability of broker/dealers to sell the Companys common shares and the ability of shareholders to sell their securities in the secondary market in the US. Moreover, the Company shares may only be sold or transferred by the Company shareholders in those jurisdictions in the US in which an exemption for such "secondary trading" exists or in which the shares may have been registered. For example, if trading on the OTC Quality Exchange under a Mergent Manual registration, the Companys shares would not be eligible for trading in all 51 states. There is no market for the Companys common shares in the United States. The Company is not listed on any stock exchange in the United States nor is there any guarantee that the Company will be listed on any stock exchange in the United States in the future. As a result, there is no market for the Companys common shares in the United States and there is no guarantee that there will be a market for the Companys common shares in the United States Risks Pertaining to the Industry Registration of products may not occur in a timely manner which could lead to delays in product introductions, reduced revenue expectations and extra costs to conduct further tests to satisfy regulatory agencies. Government agencies, such as the EPA and the Food and Drug Administration (FDA) in the United States and Health Products and Food Branch in Canada, need to provide approvals of the Companys products prior to any sales of these products.  To obtain such approvals, the Company must submit extensive amounts of information on the efficacy, toxicology, carcinogenicity, mutagenecity and other testing of the products that it is trying to register. After all of the information is provided, the agencies can request supplemental information and further testing. Once all of the requirement for documentation is satisfied, the agencies can take up to 24 months or longer to provide approvals for the Company to market its products.  Significant delays could lead to slower revenue growth than anticipated.  In addition, regulatory delays can allow time for competitors to devise strategies to prevent or reduce market penetration.  There is no assurance that government agencies will accept for registration any of the Companys products. There is a risk that the Companys intellectual property infringes upon the rights of other companies, which could lead to reduced revenues, reduced margins due to sanctions against the Company, outright withdrawal or prohibition of products or trademarks  from the market and significant costs for legal defense against infringement claims, re-branding of products and revised marketing materials. The Company is unaware of any infringement claims being made against the Company or its products or processes, except that JohnsonDiversey, Inc. (JDI) took action against the Company for use of the trademark, Viralex, which JDI claimed infringed on their trademark, Virex.  This action was settled by the Company accepting a one-time payment of US$30,000 and agreeing to cease to use the name.  The Company instead now uses the trademark T36® for its products and this trademark is registered in both Canada and the US. The change of name from Viralex to T36®caused some confusion among the customers of the Company and required additional expenditures to be made for new labels, packaging and marketing materials, as well as mailings to advise customers of the change. There was no noticeable effect on overall sales on a quarterly basis beyond normal fluctuations.  Alda Pharmaceuticals Corp. 2007 20F/A Page 11 
---------------------------------------------------------------------------------------------------------------------------------------------------------    There can be no assurances that other third parties will not assert infringement claims in the future or require the Company to obtain a license for the intellectual property rights of such third parties.  There can be no assurance that such a license, if required, will be available on reasonable terms or at all.  If the Company does not obtain such a license, it could encounter delays in the introduction of products or could find that the development, manufacture or sale of products requiring such a license could be prohibited. There is a risk that earlier inventionsmay exist that invalidate the Companys patent applications so that the Company may not be able to sell any infringing products. Since patent applications are maintained in secrecy for a period of time after filing, and since publication of discoveries in the scientific or patent literature often lags behind actual discoveries, the Company cannot be certain that it was the first creator of inventions covered by pending patent applications, or that it was the first to file patent applications for such inventions. The Company might have to participate in interference proceedings in the U.S. Patent and Trademark Office to determine priority of invention, at substantial cost. There can be no assurance that the Companys patents, if issued, would be held valid or enforceable by a court. The Company has patents allowed in the United States and China and patent applications filed in the European Union, Canada, Australia and Singapore. These patent applications seek intellectual property protection for the basic formulation of the T36®Disinfectant and the method for making it. There may be limited ability to defend the patents if and when they are issued, leading to loss of sales that might otherwise be realized if the Company was in a position to defend its patents. Litigation among pharmaceutical companies can be intense and costly.  The Company might not have the financial ability to defend its patents, if issued, against larger industry players.  Litigation may be necessary to enforce patents issued or assigned to the Company, or to determine the scope and validity of a third party's proprietary rights.  Additionally, there can be no assurances that the Company would prevail in any such action.  An adverse outcome in litigation or as part of an interference or other proceeding in a court or patent office could subject the Company to significant liabilities, require disputed rights to be licensed from other parties or require the Company to cease using certain technology or products, any of which could have a material adverse effect on the Companys business. The market for disinfectant products is competitive and well established with a number of large, multinational, widely recognized companies with significant financial and marketing resources selling, and possibly developing, similar products. Competitors are already well established in the market for disinfectant products.  The introduction of a new product into this existing market could be met with aggressive marketing, price cutting and distribution impediments by competitors.  To obtain market share, the Companys business must penetrate a market with established competitors and obtain sufficient recognition to be able to displace the existing disinfectant products.  Substantial funds will have to be spent on marketing and education to achieve these objectives.  Competitors may be developing new technologies and new products that will offer significant improvements over existing products, including those offered by the Company. There can be no assurance that others will not independently develop similar products, duplicate any of the Companys products or, if patents are issued to the Company, design around such patents.  There can be no assurance that a competitor's technology or product would be found to infringe the Companys patents. Key competitors are Germiphene Corporation, Virox Technologies, Inc., JohnsonDiversey Inc., Advanced Sterilization Products and Metrex Research Corporation. All of these companies are well established and sell disinfection products into the same markets served by the Company. The Companys T36® Disinfectant is composed of various chemicals that may pose risks due to flammability and possible health risks. One of the main components of T36® Disinfectant is ethanol, which is flammable



and, at a concentration of 95%, has a flash point (the minimum temperature at which the liquid produces a sufficient concentration of vapour above it that it forms an ignitable mixture with air) of 17oC. T36®contains 70% ethanol which raises the flash point of T36®Disinfectant to 24oC..The transport ands

S

torage of T36® Disinfectant can



pose a fire hazard



if shipped or stored in sufficient quantities. The Company uses an independent warehousing company to store and ship T36®Disinfectant. The warehouse is fully equipped with fire suppression equipment according to the relevant regulations established by the municipal, provincial and federal governments. T36®Disinfectant is shipped by ground only in cases of 4 bottles holding 4 litres each or 12 bottles holding 0.48 litres. In these quantities, T36®Disinfectant is not classified as a Dangerous Good under Sections 1.15, 1.16 and 1.17 of the Transportation of Dangerous Goods Act administered by Transport Canada. As a result, no special regulations apply to the shipping of T36®Disinfectant by  Alda Pharmaceuticals Corp. 2007 20F/A Page 12 
---------------------------------------------------------------------------------------------------------------------------------------------------------    ground within Canada. There is no guarantee that special shipping regulations will not be applied to shipments of T36® Disinfectant in the future or in other jurisdictions, such as the United States

Two potentially toxiccomponentsof T36® Disinfectant are present in low concentrations compared to their LD50 levels (the amount of the substance that kills 50% of the test population of experimental animals when administered as a single dose).


, o


O

-phenylphenol



(OPP) in pure crystalline formis considered to be a possible carcinogen and eye contact can cause severe irritation or burns with possible eye damage(Concentration in T36® Disinfectant = 2,800 ppm, oral LD50



= 2,480 mg/kg in rats).For some individuals, o-phenylphenol can also irritate the skin. Benzalkonium chloride(BZK), supplied as a 50% solution in water,has been reported to cause allergic reactions and the swelling of the mucosa when used as nose sprays on a continuous, long-term basis by sensitive users(Concentration in T36® Disinfectant = 2,000 ppm, oral LD50 = 300 mg/kg in rats)

..

The Company does not directly handle, store, use or dispose of OPP or BZK in pure form but only in their highly diluted form in T36® Disinfectant. Further, because the denatured alcohol that contains Bitrex to prepare T36® Disinfectant, the consumption of significant amounts of T36® Disinfectant is not possible. Therefore, it is unlikely that anyone can be poisoned or otherwise harmed through the proper use of T36® Disinfectant as instructed by the Company.  Toxicology studies conducted for the company by Product Safety Labs



(PSL), located in Dayton, New Jersey, have demonstratedconfirmed

  

that T36® Disinfectant is not toxichas no harmful effects on animals except as reported below by PSL: · Acute inhalation (rat): LC50 > 2020 mg/m3. Difficulty breathing, irregular respiration, lethargy and discharge from nose and eyes reported. · Acute oral (rat): LD50 > 5000 mg/kg. Lethargy and hunched posture reported. · Acute dermal (rat): LD50 > 2000 mg/kg. No systemic effects observed. · Effects not observed but possible based on individual ingredients may include: ataxia, loss of coordination, drowsiness, intoxication, nausea and vomiting. However, T36® Disinfectantbut itis classified as a moderate eye irritant.Both chemicals, o-phenylphenol and benzalkonium chloride, are present in T36®Disinfectant in relatively low levels but, given the risks described above,Although T36® Disinfectant is not measurably toxic if used as directed,it is possible that regulations against these chemicals may become more restrictive and affect the ability of the Company to market its products in certain jurisdictions without additional warning labels.None of the chemicals present in T36® pose a serious threat to the environment and are biodegradable.


Further,



However,given the attention thatsuch


anychemicals may attract from environmental groups, it is possible that negative publicity about these chemicals could affect the ability of the company to market its products in certain jurisdictions. There are persuasive arguments and credible scientific evidence that is available to support the safety of T36®Disinfectant, but such an educational effort on the part of the Company would require funds to be spent and would affect the profitability of the Company. The Company has a limited number of customers and is dependent on a few key accounts to maintain its current levels of sales. The key customers for which sales account for more than 10% of total revenues are: o Esthetics Plus, Inc.: A distributor to the beauty market with a contract

 (

Exhibit 4.h.) that renews on an annual basis. Either party can terminate the contract on 60 days notice or with 30 days notice for any breach of the contract if the breach is not rectified within the 30 day notice period,The terms of the contract are summarized below in Section 10.C, Material Contracts

. o Sinclair Dental Limited:A distributor to the dental market and a customer of both API and thethe



Company for 6nearly 4



years, o The Stevens Company Limited: A distributor to the scientific and medical markets and a customer of

both API and

the Company for nearly 46 years, and o VWR International

: A distributor to the laboratory market and customer of the

Company for nearly 4 years and o VWR International: A distributor to the laboratory market and customer of API. o Product Distribution Centre: A distributor that is owned by the provincial government of BC, supplies the provinces public sector consumers within BC and a customer of the Company for nearly 4 years. The Company currently sells its T36® Disinfectant through these distributors and is also planning on introducing new products, such as the T36® "Ready to Use" Disinfectant Cleaner, T36® Disinfectant Cleaner CONCENTRATE, and the corresponding wipes through these same distributors. The current sales and the plans to introduce the new products through these distributors would be disrupted if any of these distributors stopped representing the Company. The result would be a reduction in the Companys revenues until new distributors could be found. It is possible that new distributors could not be found and the Company would have to try to sell its products directly to the end users, leading to a significant increase in marketing and sales costs even if the sales levels could be regained.

---------------------------------------------------------------------------------------------------------------------------------------------------------    ITEM 4. INFORMATION ON THE COMPANY 4.A.   History and Development of the Company  Capital Pool Company  The Company was incorporated by registration of its Memorandum and Articles under the BC Companies Act on May 30, 2000 under the name Duft Biotech Capital Ltd. and was classified as a Capital Pool Company (CPC) on the TSX Venture Exchange. Under the policies of the TSX Venture Exchange, the principal business of a CPC is to identify and evaluate opportunities for acquisition. The completion of such an acquisition is referred to as a Qualifying Transaction. A CPC does not carry on any business other than the identification and evaluation of assets or businesses in connection with potential Qualifying Transactions, does not have business operations or assets other than seed capital and has no written or oral agreements for the acquisition of an asset or business at the time of formation. A Qualifying Transaction, pursuant to the policies of the TSX Venture Exchange, is a transaction whereby a capital pool company: (a)   Issues or proposes to issue, in consideration for the acquisition of significant assets or businesses, common shares or securities convertible, exchangeable or exercisable into common shares, which, if fully converted, exchanged or exercised would represent more than 25 percent of its common shares issued and outstanding immediately prior to the issuance; (b)   Enters into an arrangement, amalgamation, merger or reorganization with another issuer with significant assets, whereby the ratio of securities which are distributed to the security holders of the capital pool company and the other issuer results in the security holders of the other issuer acquiring control of the resulting entity; or (c)  Otherwise acquires significant assets other than cash. Qualifying Transaction On November 13, 2003, the Company completed its Qualifying Transaction, which was the acquisition of the assets of API, a private company founded in 1996 and since renamed 513947 BC Ltd. (513947). The transaction was approved by the TSX Venture Exchange as a valid Qualifying Transaction. The Company purchased the assets of API with 3,711,263 shares of the Company valued at 20 cents per share, for a total share value of $742,252.60, plus forgiveness of loans and accrued interest of  $57,747.40 advanced to API by the Company prior to completion of the Qualifying Transaction. The total transaction price of the Qualifying Transaction to the Company was therefore $800,000. The Company purchased only the assets and not the liabilities of API except for the trademark litigation undertaken by JohnsonDiversey Inc. against API. This litigation was subsequently settled and is discussed elsewhere. As a result of the asset purchase, API became the registered owner of the shares of the Company. The Company also acquired the intellectual property and $17,500 worth of inventory from API. The intellectual property consisted of theone

The parties to the Voting Agreement, dated November 13, 2003 and established as a condition of completing the Qualifying Transaction, are API, Allan Shapiro (Shapiro), Michael Wilby (Wilby), the Company, Terrance Owen (Owen), Peter Chen (Chen) and Bruce Schmidt (Schmidt).   Alda Pharmaceuticals Corp. 2007 20F/A Page 14 
---------------------------------------------------------------------------------------------------------------------------------------------------------    Under the terms of the agreement, API, Shapiro and Wilby will vote their shares of the Company in favour of  the number of directors of the Company not to exceed six directors with one director being independent of API and the election of Owen, Chen and Schmidt as directors of the Company provided they have been nominated by the Company for election to the Board of the Company;  Until termination of this Agreement, the Company will nominate Owen, Chen and Schmidt for election to the Board at each Meeting provided each person consents to continuing as a director of The Company, is not then prohibited by law from serving as a director of The Company and that each nomination and election is acceptable to the TSX Venture Exchange and all other applicable securities regulatory authorities.  Subject to restrictions imposed under applicable securities legislation, API, Shapiro or Wilby may sell shares of the Company through a stock exchange. If any of them proposes to sell in excess of 200,000 shares of the Company in an off-market transaction they will require the purchaser to agree to be bound by the terms of the Voting Agreement.  If a take-over bid or other offer is made to shareholders of the Company by an arms-length third party for all or a portion of the shares of The Company, API, Shapiro and Wilby will be free to tender to such bid or offer any shares owned by them and will not be required to comply with the selling restrictions described above.  The Voting Agreement will terminate with respect to Wilby, at the earlier of: · such time as API, Shapiro and Wilby collectively cease to hold, directly or indirectly, less than 10% of the issued voting shares of The Company; · such time as Wilby ceases to hold directly or indirectly, or control at least 5% of the issued voting shares of The Company; and · 5 years from the date of the execution and delivery of this Agreement.  The Voting Agreement will not terminate with respect to API and Shapiro, except with the consent of the TSX Venture Exchange. As of June 30, 2007, the Voting Agreement is no longer in effect for Wilby since his personal shareholdings are below 5% of the issued voting shares of the Company.  On November 1, 2004, the Voting Agreement was amended. The parties to the Amendment are API, Shapiro, Wilby, the Company, Owen, Chen and Schmidt.  The Amendment was entered into because of the name changes undertaken by the Company and API after completion of the Qualifying Transaction and the resignation of Schmidt as a director of the Company. The Amendment also changed references to Owen, Chen and Schmidt to Owen Nominee, Chen Nominee and Schmidt Nominee, respectively, so that, if any one of Owen, Chen or Schmidt does not consent to being nominated as a director of APC, another person acceptable to the TSX Venture Exchange and to the other nominees would become a party to the Voting Agreement. On October 4, 2004, Eugene Hodgson was appointed as a director and became the Schmidt nominee on completion of the Amendment.  Escrow Agreement  Of the 3,711,263 shares issued to API, 90% or 3,340,137 were held in escrow. Under the terms of the Escrow Agreement, there has been a 15% release every 6 months on May 14, 2004, November 14, 2004, May 14, 2005, November 14, 2005 and May 14, 2006 and November 14, 2006. No shares remained in escrow on June 30, 2007.


An Escrow Agreement, dated November 13, 2003, was automatically terminated on November 14, 2006 due to the release of all remaining escrowed securities on that date.  Non-Competition Agreement (Exhibit 4.i.) The parties to the Non-Competition Agreement, dated November 13, 2003 and established as a condition of completing the Qualifying Transaction, are API, Shapiro and the Company.  Under the terms of the Agreement, API and Shapiro agree that neither Shapiro nor API will compete with the Company in any way. In the case of API, the Agreement expired after one year on November 13, 2004. In the case of Shapiro, the Agreement stays in place while Shapiro provides services for the Company in any capacity and for a period of one year after his services for the Company come to an end. Competition, as defined in the Agreement, includes, but is not limited to, the solicitation of customers or the sale of any products or services that are in any way similar to those offered by the Company or inducement of any employees of the Company to leave the Company. Shapiro agrees that any breach of the agreement by him could cause irreparable harm to the Company and that the Company can take any action that it deems necessary to end the breach and be compensated for the breach.

Business Overview  The Company was established in order to develop and commercialize disinfectant products.  The Company has called the disinfectant technology T36® Disinfectant.  T36®Disinfectant is a mixture of ethanol, o-phenylphenol, benzalkonium chloride and other ingredients (including lemon fragrance and water).  All of these component chemicals are bio-degradable. The Company is attempting to patent or secure proprietary protection for the specific combination of these products although the ingredients are all common chemical compounds. During its first five years, Companys primary focus has been on product development. The Companys first product, a surface disinfectant called Viralex and subsequently renamed T36®Disinfectant, was launched in September of 2001. It is being sold primarily to (i) First Responder organizations including ambulance, fire fighters and police forces in Canada, (ii) dental clinics, and (iii) beauty and hair care salons and spas. T36®Disinfectant has been approved by Health Canada for use on any hard, inanimate non-porous surfaces.  This includes, but is not limited to, counter tops, cutting boards, sinks, tubs, walls, floors, windows, mirrors, scissors, nail clippers and other equipment used in beauty salons and spas, dental mirrors and other equipment in dental offices, and equipment used by firefighters, police and paramedics. T36® Disinfectant is also approved by the Canadian Food Inspection Agency (CFIA) for use in restaurants and other facilities where food is prepared.  Alda Pharmaceuticals Corp. 2007 20F/A Page 16 
---------------------------------------------------------------------------------------------------------------------------------------------------------    Efficacy studies Efficacy studies refer to proving a drug's effectiveness (in this case as a disinfectant) in producing a desired result (bactericide, virucide, fungicide or tuberculocide).In studies conducted by independent laboratories in Canada and the United States, T36®Disinfectant has demonstrated efficacy againstmore than 50 differentbacteria, fungi and viruses.The types of surfaces tested were hard, non-porous surfaces unless otherwise noted..These studies included the following: 1. An eEfficacy study,dated February 10, 1997,



wasconducted by British Columbia Research Inc.(University of British Columbia,(Vancouver, Canada) under the supervision of Dr. Ernie Lee, dated February 10, 1997.The


Study concluded that the T36®Disinfectant successfully killed


 organisms tested werefour strains of bacteria (Staphylococcus epidermis, Pseudomonas aeruginosa, Serratia marcescens, and Mycobacterium tuberculosis)one strain of yeast (Candida albicans),spores fromone strain of fungus (Aspergillus fumigatus)and two strains of viruses (Herpes Simplex Virus-1 and Poliovirus-1)in compliance with test standards accepted by Health Canadas Therapeutic Product Directorate..;Twenty five replicates of each organism at low levels, ranging from 38 to 177 cfus/ml (colony forming units/ml) were dried on microscope cover slips and exposed to T36® Disinfectant for varying times. The studies demonstrated that T36® Disinfectant was 100% effective against all five organisms after 10 minutes or longer contact times. At shorter contact times, the kill rate for all 5 organisms ranged from 95.5% to 97.2% after a 1 minute exposure and 98.7 and 99.0% after a 5 minute exposure.. 2. An efficacy study, dated June 6, 1997, wasEfficacy studyconducted by Dr. Richard Stokes of the University of British Columbia in conjunction with the British Columbia Childrens Hospital, dated June 6, 1997.Twenty replicates ofMycobacterium tuberculosisat approximately 107cfus/ml were dried on microscope cover slips and exposed to T36® Disinfectant for varying times. The studies demonstrated that the kill rate was 99.99997% (a reduction of log10 = 6.46) and 99.99998% (a reduction of log10 = 6.59)  after a 10-minute exposure. The requirement for a disinfectant to be designated as Tuberculocidal by Health Canada is a log10reduction of 6.0 or greater

.. 3. Study concluded that the T36®Disinfectant was efficacious as against

Mycobacterium tuberculosis

; 4. Suspension tests for efficacy completed September 17, 1997 against HIV at the St. Pauls Hospitals John Ruedy Immunodeficiency Clinic (Vancouver, Canada) under the supervision of Dr. Brian Conway. Study concluded that the T36®Disinfectant was 100% efficacious on the HIV virus on contact and still had 100% efficacy at dilution of 1:43 (one part T36®to 43 parts water); and 5. Efficacy studies



were conducted by Viromed Biosafety Laboratories of Minneapolis, Minnesota, and



completed on February 23, 2000. The




Study concluded that the T36®Disinfectant successfully killed the test

organisms



tested were Staphylococcus aureus, Pseumomonas aeruginosa, Salmonella choleraesuis, Human Immunodeficiency Virus Type I, Herpes simplex Virus Type 1, Trichophyton mentagrophytesand Poliovirus Type 1, in compliance with test standards accepted by the Environmental Protection Agency (EPA)



of the United States. · For each of the bacteria,Staphylococcus aureus, Pseumomonas aeruginosa, Salmonella choleraesuis, 180 replicates at 6.1 x106 cfu/ml (log10 = 6.79), 1.9 x 106 cfu/ml (log10 = 6.28) and 1.7 x 104 cfu/ml (log10 = 4.23), respectively, were dried on microscope slides and exposed to T36® Disinfectant for 3 minutes. For bothStaphylococcus aureusandPseumomonas aeruginosa, growth was observed on only 1 replicate out of 180. ForSalmonella choleraesuis, none of the 180 replicates showed any growth. These results met the requirement that no more than 1 replicate out of 60 can show growth and T36® Disinfectant was deemed to demonstrate efficacy against all three bacteria. · For Human Immunodeficiency Virus Type I, six replicates at 1.77 x105 cfu/ml (log10 = 5.25), were dried on the bottom of Petri dishes. After being exposed to T36® Disinfectant for 3 minutes, none of the replicates showed any viral activity and T36® Disinfectant was deemed to demonstrate efficacy against HIV. · ForHerpes simplexVirus Type 1, six replicates at 5.6 x106 cfu/ml (log10 = 6.25), were dried on the bottom of Petri dishes, After being exposed to T36® Disinfectant for 3 minutes, none of the replicates showed any viral activity and T36® Disinfectant was deemed to demonstrate efficacy against the Herpes virus. · ForPoliovirusType 1, six replicates at 5.6 x105 cfu/ml (log10 = 5.75), were dried on the bottom of Petri dishes. After being exposed to T36® Disinfectant for 3 minutes, none of the replicates showed any viral activity and T36® Disinfectant was deemed to demonstrate efficacy against the Polio virus. · For the fungus,Trichophyton mentagrophytes,twenty replicates at 4.6 x104 cfu/ml (log10 = 4.66), were dried on microscope slides. After being exposed to T36® Disinfectant for 3 minutes, none of the replicates showed any viral activity and T36® Disinfectant was deemed to demonstrate efficacy againstTrichophyton mentagrophytes.. Efficacy studies refer to proving a drug's effectiveness (in this case as a disinfectant) in producing a desired result (bactericide, virucide, fungicide or tuberculocide). Toxicology is the study of the adverse effects of chemical, physical or biological agents on living organisms and the ecosystem, including the prevention and amelioration of such adverse effects. The types of surfaces tested were hard non-porous surfaces. The above studies demonstrated that T36®Disinfectant was effective in inactivating polio viruses within 3 minutes and tuberculosis mycobacteria within 5 minutes. Polio and tuberculosis are benchmark micro-organisms because they are among the most difficult to kill with disinfectant products. Efficacy against polio and tuberculosis demonstrates a high level of disinfection capability. In order to make a virucidal claim and a tuberculocidal claim, a disinfectant product must demonstrate its ability to destroy the poliomyelitis type 1 virus, andMycobacterium bovis or tuberculosis mycobacteria within a specified time. This is mandated in Canada by the Canadian General  Alda Pharmaceuticals Corp. 2007 20F/A Page 17

The studies conducted at ViroMed Biosafety Laboratories in the U.S., and at British Columbia Research Incorporated (BCRI) in Canada used between 10 and 60 samples each, depending on the organism tested.

In all casesof the testing described above,a control was utilizedcontrols were used



to validate the testing protocols. A positive test result required complete inactivation of the tested viruses and complete efficacy against the fungi and bacteria as required by the U.S. EPA for disinfectant label claims. The results from BCRI demonstrated efficacy in excess of Log10 4.0 (i.e. 10,000 times reduction in micro-organisms) in compliance of the standards required in Canada. The tuberculocidal studies demonstrated results in excess of Log10 6.0 (1,000,000 times reduction in micro-organisms).

Additional t


Thetoxicology studieslisted belowwere conducted in the United Statesby Product Safety Labs in East Brunswick, New Jersey, USA and completed in November, 1999that demonstrated that T36®Disinfectant is safe to use, as well as non-corrosive and non-caustic.These studies were conducted by Product Safety Labs in labs in East Brunswick, New Jersey, USA and completed in November, 1999. · Acute Oral Toxicity Study in Rats - This test determines the amount of a substance that kills 50% of the test population of experimental animals when administered as a single dose. Five thousand milligrams of T36® Disinfectant per kilogram of bodyweight was administered orally to ten healthy rats. The animals were observed for mortality, signs of gross toxicity, and behavioral changes at least once daily for 14 days. Bodyweights were recorded prior to administration and again on Days 7 and 14. Necropsies were performed on all animals at terminal sacrifice. All animals survived and gained weight during the study. Following administration, most animals exhibited piloerection (erection of the hair), hunched posture and/or were hypoactive. Apart from one female that exhibited reduced fecal volume between Days 0 and 5, all affected animals recovered from the above symptoms. Based on the results of this study, the single dose acute oral LD50 of T36® Disinfectant is greater than 5,000 mg/kg of bodyweight · Primary Skin Irritation Study in Rabbits -  This test determines the potential for a substance to produce irritation after a single topical application. Five-tenths of a milliliter of T36® Disinfectant was applied to the skin of three healthy rabbits for 4 hours. Following exposure, dermal irritation was evaluated and no dermal irritation was noted at any dose site during the study. Based on the results of this study, T36® Disinfectant is classified as non-irritating to the skin. · Primary Eye Irritation Study in Rabbits - This test determines the potential for a substance to produce irritation from a single dose to the eye. One-tenth of a milliliter of T36® Disinfectant was placed into the right eye of six healthy rabbits. The treated eyes of three rabbits were rinsed with physiological saline after instillation. The eyes of the remaining three rabbits were not rinsed. The left eye remained untreated and served as a control. Ocular irritation was evaluated and, based on the results of this study,T36® Disinfectant is classified as moderately irritating to the unrinsed eye and severely irritating to the rinsed eye. · Acute Inhalation Toxicity Study in Rats - This test determines the potential for a substance to produce toxicity from a single exposure via the inhalation route. Ten healthy rats were exposed to T36® Disinfectant vapours in a closed chamber at a concentration 2.02 mg/L for 4 hours. The animals were observed for mortality, signs of gross toxicity, and behavioral changes at least once daily for 14 days thereafter. Bodyweights were recorded prior to exposure and again on Days 7 and 14. All animals survived exposure to the test atmosphere and gained bodyweight over the 14-day observation period. During the exposure, the rats exhibited ocular and nasal discharge, shortness of breath, irregular respiration, shallow respiration, hunched posture and hypoactivity. With the exception of ocular and nasal discharge and shallow respiration, similar clinical signs persisted in all animals upon removal from the exposure chamber. Some animals also developed noisy breathing, reduced fecal volume and/or a prone posture, but all rats recovered from these symptoms by Day 11 and appeared active and healthy for the remainder of the study. Necropsy findings at terminal sacrifice were unremarkable. Based on the results of this study, the single exposure acute inhalation LC50 of T36® Disinfectant is greater than 2.02 mg/L. · Acute Dermal Toxicity Study in Rats - This test determines the health hazards likely to arise from a short-term exposure to a substance from a single topical application to the skin. Two thousand milligrams per kilogram of bodyweight of T36® Disinfectant was applied to the skin of ten healthy rats for 24 hours. The animals were observed for mortality, signs of gross toxicity, and behavioral changes at least once daily for 14 days. Bodyweights were recorded prior to application and again on Days 7 and 14. Necropsies were performed on all animals at terminal sacrifice. All animals survived, gained weight and appeared active and healthy. There were no signs of gross toxicity, adverse pharmacologic effects or abnormal behavior. Gross necropsy findings at terminal sacrifice were unremarkable. Based on the results of this study, the single dose acute dermal LD50 of T36® Disinfectant is greater than 2,000 mg/kg of bodyweight.   Alda Pharmaceuticals Corp. 2007 20F/A Page 18 
---------------------------------------------------------------------------------------------------------------------------------------------------------    · Dermal Sensitization Study in Guinea Pigs - This test determines the potential for a substance to produce sensitization after repeated topical applications. T36® Disinfectant was topically applied to twenty healthy test guinea pigs, once each week for a three week induction period. Twenty-seven days after the first induction dose, a challenge dose of T36® Disinfectant at its highest non-irritating concentration (100%) was applied to a new site on each guinea pig. Ten untreated animals were maintained under the same environmental conditions and treated with T36® Disinfectant at challenge only. Approximately 24 and 48 hours after each induction and challenge dose, the animals were scored for erythema (redness of the skin). Based on the results of this study, T36® Disinfectant is not considered to be a contact sensitizer..   There were no p-values nor statistical significance employed in the studies because such measurements are not required by Health Canada or the EPA and, therefore, are not part of the standard protocols. There were no further requirements for the Company to undertake further studies.  T36®Disinfectants Heath Canada Drug Identification Number (DIN) is 02231344. The Company is also in various stages of development of other products including: 1. "Ready to Use" Disinfectant Cleaner: This product has been recognized by Health Canada as being able to kill bacteria, fungi and viruses on hard surfaces within 10 minutes (compared to the 3 to 5 minute time for T36®Disinfectant).  It has also passed internal company efficacy testing.  This product is intended for use in hospitals, cruise lines, airlines and consumer applications that dont require a disinfectant product that is as fast acting as T36®Disinfectant, but need a more economical  product.

.

  The Health Canada DIN for this product is 02272989 The Company has not determined when manufacturing will be started or when revenues will be realized from this product.



At the present time, there are no plans to conduct further testing or to register the product in any jurisdiction outside of Canada

.. 2. Disinfectant



Cleaner CONCENTRATE: This product has completed testing and is registered with Health Canada (DIN 02278820). For US sales, EPA registration is required at an estimated cost of  $100,000. Completion of the required US registration is dependent on financing. The EPA registration is projected to be completed 2 years after financing is available. International sales are important to the Company and delays in US registration could have a significant effect on future sales and cash flow, as well as allow competition to penetrate this market. It is not known when manufacturing will be started or when revenues will be realized from this product.



At the present time, the Company is considering conducting further testing to satisfy the requirements of the EPA for disinfectant cleaners and applying for registration of the product in the United States. It is not certain when this testing will begin and the decision may be made not to proceed at all if sales in Canada do not seem to warrant the expense of seeking EPA registration

.. 3. Hand Sanitizer:  In February 2006, the Company started marketing of its hand sanitizer product (Health Canada DIN 02247771) through its current distributors to existing customers.  Up to June 30, 2007, there have been sales of approximately $50,000 of this product. No further testing or registrations are planned. 4. T36® Personal Disinfectant, T36® Disinfectant Wipes and "Ready to Use" Disinfectant Cleaner Wipes: These products have been designed for use by general public for cleaning and disinfecting their hands or hard surfaces. Development has been completed and both products are registered with Health Canada (DINs  02231344 and  02272989, respectively). No further testing or registrations are planned and no final product has been manufactured or marketed up to June 2007. It is not known when manufacturing will be started or when revenues will be realized from these products. Delays may cause reductions in anticipated revenue generation. 5. Anti-viral Soap: The Company has developed an anti-viral, anti-bacterial soap.  As at June

his delay could allow competition to penetrate this market, which could reduce the revenue potential for this product. 6. Microbicide Gel: This product has been formulated and now requires testing for efficacy and toxicity. It was developed as a personal lubricant to prevent the transmission of sexually transmitted infections (STIs). The testing required to attain FDA approval of this product would be beyond the financial capabilities of the Company. Therefore, the Company intends to



undertake some initial testing on its own after a suitable delivery system has been identified and the rights to that delivery system acquired. If initial testing is successful, it is most likely that the Company will need to






identify a licensee or joint venture partner working in the area of STI prevention that can undertake thefurther



testing and market development. It is no

---------------------------------------------------------------------------------------------------------------------------------------------------------     7. Topical infection treatment: The body normally hosts a variety of microorganisms, including bacteria and fungi. Some of these are useful to the body. Others may multiply rapidly and form infections. Approximately sixty percent of microbial infections are systemic meaning that the infections are spread throughout the body, leaving 40% of microbial infections that are topical, i.e., occur on the surface of the body. Topical fungal infections include mold-like fungi that cause athlete's foot, jock itch and ringworm, and yeast-like fungi that can cause diaper rash, oral thrush, cutaneous candidiasis and some cases of genital rashes. Bacterial infections, such as Staphylococcus can also infect the skin, particularly if a patient has a preceding skin condition, such as eczema. The Companys T36® formulation can be used to treat such topical infections and anecdotal evidence has shown that it can be used to treat such conditions as athletes foot and toenail infections. This application of the T36® formulation must be tested against such conditions according to the requirements of the FDA, Health Canada and the European Medicines Agency



and the Company intends to conduct such testing as soon as possible. Once the testing is completed, the results must be submitted to these regulatory agencies and be approved for marketing by the company. However,

---------------------------------------------------------------------------------------------------------------------------------------------------------    The Company does not keep separate records of the cost of the development and registration for each product for a number of reasons. First, much of the development had already been done on the products before the Company acquired the assets of API in November, 2003 and API did not keep such records. Second, the Companys expenditures after completing the acquisition of the assets of API have mostly involved registration, intellectual property protection and some testing. These expenses are recorded in separate categories from research and development in the financial statements. Third, the level of expenditures by the Company would be relatively small if they were allocated to individual products and would not be considered to be material if expenditures on each product were considered on their own. Finally, the cost of accounting for such a variety of expenditures on such a number of products is not considered to be financially justified. Limited information has been provided on the estimated time of completion for individual products and for the estimated time of material net cash inflows for a number of reasons. Testing in the US for applications to the FDA or the EPA, in Canada for Health Canada and in Europe for the European Medicines Agency, is dependent on financing to support these tasks. The timing of financing and even the availability of financing is uncertain, which mean that completion dates and the time required to achieve material net cash flows are also uncertain. Even when the financing is available to complete testing and prepare the required submissions to the regulatory bodies, the time taken by the regulatory agencies to review the submissions is unpredictable. Further, the regulatory agencies may identify deficiencies in the submission and request more documentation or possibly even more testing before providing an approval for a product, if such approval is granted at all. Since the timing to secure product registration and market approval is uncertain and delays can lead to the entrenchment of competitors and make the penetration of markets more difficult, even more uncertainty is added to the estimates of time required to time to arrive at material net cash flows. For these reasons, the Company believes that it is more prudent to not project the times or costs of market approval for individual products.  Plan Of Operations Source of Funds for Fiscal 2008 and for Fiscal 2009 The Companys primary source of funds since incorporation has been and continues to be through the issuance of common shares since sales revenues are not yet rising. As of June 30, 2007, the Company had a deficit of $2,603,791.  Use of Funds for Fiscal 2008/2009 For the 18 months ending December 31, 2008 the Company estimates that it will require the following to fund planned operations:  General Office and Administrative Expenses: $   700,000 New Products Research and Development: $   100,000 US securities fees and expenses (related to Form 20F filing): $     30,000 Sales and Marketing: $   235,000 Patenting activities: $     30,000 Regulatory activities (1): $   150,000 New Product Sample Inventory / Production (2): $     20,000 Total: $1,265,000 Less Anticipated Revenue: $   300,000 Additional Funds required: $   965,000 Working Capital (as of June 30, 2007): $   627,730 TOTAL ADDITIONAL FUNDS REQUIRED: $   337,270  (1) Regulatory Activities refers to performance of toxicology, efficacy and other studies required to secure FDA, EPA and other regulatory approvals so that the Company can sell in markets outside of Canada and also refer to securing Health Canada Drug Identification Numbers for Canadian approvals for the Companys new products. (2) New Product Sample Inventory / Production refers to the costs of producing samples for market and consumer testing of those products the Company is developing.  Anticipated Changes to Facilities/Employees Management of the Company anticipates no changes to either its facilities or personnel, including number of employees, in Fiscal 2008. As distribution and sales are done on a wholesale price basis, sales revenue changes do not result in changes in the number of personnel or the Companys facilities. As production is being performed on a contract basis with Norwood Packaging Ltd. (see Exhibit 4.Bb.) changes in product sales do not result in changes to the Companys facilities or personnel.  United States vs. Foreign Sales/Assets All of the Companys assets are located in Canada. All of the Companys sales to date have been in Canada.  Material Effects of Government Regulations At this time, our sales are primarily in Canada and, as a result, government regulations in Canada affect the Company most significantly.  However, the Company hopes to commence sales in the United States, China, Europe and other jurisdictions in the future and, as a result, we have summarized the government regulations in these markets that may affect the Company in the future. The Companys products and future planned products can be categorized either as disinfectant products or therapeutic products, depending on the intended use. A summary is provided on the government regulations for both of these product categories. 1. Canada: In order to market and sell a disinfectant, which is classified as a drug in Canada, the product must be approved by Health Canada, a federal government department responsible for the oversight of drugs and certain other medical products. The Therapeutics Product Directorate (TPD) is the department of Health Canada that issues the DIN (Drug Identification Number) for registered products.  A company can apply for a DIN by submitting the appropriate fee, a draft label and, in most cases, copies of completed efficacy and safety studies to support the claims made on the label. The descriptions of the tests required for Health Canada approval of a disinfectant are described above in the sections entitled Efficacy studies and Toxicology studies..



The TPD generally takes 7-up to



12 months for review and completion prior to the issuance of a DIN. However, if further documentation or studies are required, the time taken to obtain approval for a new product can be longer. T36®Disinfectant has received approval from Health Canada as a disinfectant, disinfectant cleaner, sanitizer and deodorizer. The DIN for T36 Disinfectant is 02231344, which permits its sale in Canada for these applications.  T36®Disinfectant has also been approved in Canada by the Canadian Food Inspection Agency for use in Registered Establishments, which include meat processing plants, restaurants, breweries, wineries and other commercial food processing establishments.  Alda Pharmaceuticals Corp. 2007 20F/A Page 21 
---------------------------------------------------------------------------------------------------------------------------------------------------------    Production facilities that manufacture an approved product must have an Establishment License that verifies its adherence to Good Manufacturing Practices (GMP) as set out by a division of Health Canada.  Norwood Packaging Ltd. (Norwood), which produces the Companys products under contract (see Exhibit 4.Bb.), has an Establishment License. The Companys agreement with Norwood, dated September 29, 2005



(Exhibit 4.b.), requires Norwood to manufacture and store T36®Disinfectant for the Company in exchange for a percentage of sales made by the Company. The percentage paid to Norwood varies with the size of the order and for certain customers. Norwood also has a Right of First Refusal to manufacture other products for the Company under similar terms. The termination provisions of the agreement are standard commercial terms that include uncorrected breaches of the agreement, any form of insolvency on the part of Norwood or the Company, or 90 days written notice by either party. There is no specified expiry date for this agreement. 2. United States:In order to market and sell a disinfectant in the US, the product must be approved by either the US Food & Drug Administration (FDA) or the US Environmental Protection Agency (EPA), depending on the intended use.  Disinfectant products, such as hard surface disinfectants, are regulated by the EPA.The descriptions of the tests required for EPA approval of a disinfectant are described above in the sections entitled Efficacy studies and Toxicology studies

..

Any products with therapeutic claims or intended for use on humans are regulated by the FDA.  It is illegal to market and sell therapeutic products in the United States without an FDA or EPA registration. At some point in the future, the Company intends to undertake the processes in the United States to obtain FDA or EPA registration numbers.

In the United States, T36®Disinfectant must be registered with the Environmental Protection Agency (EPA) as a disinfectant, disinfectant cleaner, sanitizer and deodorizer. The Company entered into an agreement with Phigenics, LLC on July 21, 2005 (see Exhibit 4.A. for details of the Companys contract with Phigenics). Phigenics will provide a contribution in kind of up to $33,000 at a mutually agreeable per diem rate to: (a)   Assist the Company with the registration of T36® Disinfectant with the US Environmental Protection Agency (EPA), (b)  Work with the Company to develop new formulations of T36®Disinfectant, and (c)  Develop sales and distribution channels in the US, For these services, the Company will provide up to US$32,000 for EPA product registration fees, provide Phigenics with a royalty on Net Sales (gross sales less refunds and returns) of  T36®Disinfectant in the US starting 90 days after the Registration is achieved. The royalties will be 7% for the first year until 150% of Phigenics contribution in kind has been repaid and then 5% for the remainder of the first year, 5% for the second year, 4% for the third year, 3%  for the fourth year, 2% for the fifth year and 1% for the sixth and seventh years. In addition, Phigenics will receive a finders fee of 5% of sales to new clients for the first year after the first sale and 3% for the next year. The agreement with Phigenics contains neither a term nor termination provisions.

The Company cannot say when, or even if, the proposed submissions to the EPA and the FDA will be completed.  The Company cannot predict the timing of FDA or EPA approval, if such approval can be obtained. FDA product registrations may



require the following tests for each therapeutica topical therapeutic test substance, such as T36®Disinfectant

..


product: · Time kill Evaluation



In these tests, dozens of different species of infectious micro-organisms are exposed to each of the active ingredients of a test substance and the complete test substance formula for periods of time ranging from 15 seconds to 30 minutes to determine the time required for each ingredient of a test substance and the complete test substance formulation to completely kill the selected species. The objectives of the testing are to determine the effective exposure times required for the test substance to be effective and if the individual ingredients have an additive, subtractive or synergistic effect.. · ,

MIC (Minimum Inhibitory Concentration) Evaluation

 

Each ingredient of a test substance, the complete test substance formula and a known antiseptic product are tested against hundreds of micro-organisms. The objectives of the tests are to quantify the minimum concentration that is required for each of the test substances to have a measurable effect on the tested species, compare those results to the known antiseptic product and determine if the individual ingredients have an additive, subtractive or synergistic effect. · In-vitrodermal test  This testing involves in-vitro preparation and contamination of pig skin that has been harvested from carcasses with bacteria to evaluate the methods of application of a test substance and the time of exposure to achieve the best anti-microbial results. The objective of the testing is to determine the methods that would be proposed for subsequent human trials.. · ,

The study evaluates the immediate and persistent antimicrobial properties of a disinfectant when used as a preoperative skin preparation.  A known active control, e.g., 4% chlorhexidine, and a placebo, e.g., sterile saline, are also evaluated.  All treatments are assessed for their potential to cause skin irritation.  One-hundred  subjects are screened in order to obtain at least forty subjects having sufficient number of resident bacterial flora to permit evaluation of the efficacy of the test products. The objective of this test is to further evaluate the efficacy of a test substance when used on humans..  Alda Pharmaceuticals Corp. 2007 20F/A Page 22 
---------------------------------------------------------------------------------------------------------------------------------------------------------     · Pharmacokinetics describes how the body affects a specific drug after administration and examines the extent and rate of Absorption, Distribution, Metabolism and Excretion, commonly referred to as the ADME scheme. Absorption is the process of a substance entering the body. Distribution is the dispersion or dissemination of substances throughout the fluids and tissues of the body. Metabolism is the irreversible transformation of parent compounds into daughter metabolites. Excretion is the elimination of the substances from the body. In rare cases, some drugs irreversibly accumulate in a tissue in the body. The pharmacokinetic properties of drugs may be affected by elements such as the site of administration and the concentration in which the drug is administered. These may affect the absorption rate. The objective of the ADME studies are to determine if the test substance or any of its components are absorbed and if any absorbed components are metabolized into harmful chemicals that may or may not accumulate in the body. · Insult patch test  The objective of this test is to evaluate the effect, if any, of prolonged and repeated exposure of the skin to the test substance. The Induction Phase of this study incorporates the test substance into a series of patches that are applied to the skin of 50 subjects repeatedly for periods of time and then removed. After a rest period, new patches are applied. This process is repeated over a period of time with a number of new patches and after completion of this phase, the reaction of the skin is evaluated. The Challenge Phase takes place some time after application of the final induction patch. Challenge patches are applied to previously untested sites, adjacent to the original induction patch sites. The reaction of the skin is evaluated 24 to 48 hours after application and the subjects are asked to report any delayed reactions which might occur after the final challenge patch reading

These tests would typically require 12-18 months to complete and must be conducted by FDA certified labs. The FDA review and approval of this data can take up to 24 months. Once approved, then human clinical trials (if required) would need to be completed.  These trials are normally conducted in 3 phases, with a detailed protocol for each phase provided to the FDA for approval to proceed. At the end of each phase, the results are analyzed and submitted to the FDA and, if acceptable, the trial continues to the next phase: Phase I Clinical Trials: This is the first stage of testing of a new therapeutic in human subjects, normally with a small group (20-60) of healthy volunteers. The objective is to assess the safety and tolerability of the product as a therapeutic, as well as to determine the effects of various doses of the product.  For externally administered agents, the testing is simpler than for injected or internally administered agents. However, Phase 1 trials can require up to 2 years to complete, including analysis of the collected data, preparation of the Phase I report for submission to the FDA and the time until a response is received. If these results of Phase I are accepted by the FDA, then the clinical trial can proceed to Phase II. Phase II Clinical Trials: This second phase tests the therapeutic on a larger group and evaluates both the required dose (i.e. different quantities of the therapeutic) and efficacy (i.e. how well the therapeutic works for the specified indication). Phase II trials can take up to 3 years. However, some trials can combine Phase I and Phase II, which can reduce the total time required. Phase III Clinical Trials: This third phase of clinical trial depends on the indications for which the therapeutic is being tested. For most agents Phase III trials are a randomized, controlled, multi-center trial with large patient groups (often more than 300), with the objective of  confirming that the therapeutic is as effective or more effective than the current gold standard for the same application. Phase III trials can take up to 5 years or more to complete.  If the results of the Phase III trial are approved by the FDA, then product is approved for marketing for the specific indications that were tested. The three phases of clinical trials can require as long as 5-10 years to complete even for topical products. The total time required is dependant on the nature of the therapeutic, the condition being treated, the design of the protocols, the time to recruit patients and the review process conducted by the FDA. The registration time for products taken internally can take much longer than for topical agents. The costs of a complete clinical trial can be significant, depending on the intended application.  The Company may not conduct any clinical trials itself, but may enter into strategic alliances or licensing agreements with larger companies, which can support the costs of such trials,  Alda Pharmaceuticals Corp. 2007 20F/A Page 23 
---------------------------------------------------------------------------------------------------------------------------------------------------------     1. China: In the Peoples Republic of China (China), the Company must have its products tested for toxicology and efficacy at the Centers for Disease Control (CDC).  The CDC should not be confused with the CDC in Atlanta, Georgia, although both organizations share the same name. The studies required by the CDC include the following tests..  · Kill tests againstStaphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa In a suspension test, the disinfectant must provide a log10 reduction in bacterial population of 5.0 or more within a test time designated by the supplier of the disinfectant. A suspension test involves adding the bacteria to the disinfectant, usually at a ratio of 0.1 to 2 parts bacterial suspension to 9.9 to 8 parts disinfectant, respectively. · Field disinfecting test on general hard surfaces  General bacterial counts are first determined on table surfaces and the window frame surfaces, maintained at 19 to21 oC, by taking sample swabs and culturing the bacteria. The same surfaces are then wiped with the disinfectant and sampled after a test time designated by the supplier of the disinfectant. The disinfectant must provide a average log10 reduction in bacterial population of 2.0 or more in this test. · Metal corrosion test - Metal plates made of  stainless steel, carbon steel, copper and aluminum are immersed continuously for 72 hors in the disinfectant. The corrosion rate, measured in millimeters per annum, is then determined for each metal. · Acute oral toxicity test - Four dosage groups receive 1,000, 2,150, 4,640, and 10,000 mg/kg of disinfectant administered orally with 10 animals in each group and comprised of half females and half males. After exposure to the disinfectant, the general conditions, symptoms of toxicity, and deaths of animals are observed over a period of 2 weeks.  After the tests are finished, all animals are dissected and gross pathological changes of animals are recorded.  Acute toxicities are measured in terms of the LD50, the dose at which 50% of the animals die. · Bone marrow erythrocyte micronucleus test - Rats are given a dose of 500, 2,000, and 5,000 mg/kg of disinfectant by gastric lavage. Each group consists of 5 females and 5 males. Thirty hours later, the rats are given a second dose that is identical to the first. Six hours later, the rats are killed and dissected. Bone marrow from the sternum is removed, smeared on microscope slides, stained and examined for signs of chromosomal mutations. · Skin irritation test - Twenty-four hours before testing, a 3 cm x 3 cm area beside both sides of spinal cords on the backs of three New Zealand rabbits is shaved. On the next day, a testing area of 2.5 cm x 2.5 cm on the shaved skin on the left side is marked and 0.5 ml of disinfectant is smeared evenly on the test area, covered by 2 to 4 layers of gauze the same size as the test area and one layer of cellophane which is a little bigger than testing area for each animal. The test area is directly exposed to the disinfectant in this way for 4 hours. The shaved area on the right side is exposed to saline as a negative control using the same procedure. After the 4 hour exposure, the dressings are removed and shaved areas are washed using warm water to remove any residual saline or disinfectant.  After 1, 24, and 48 hrs the level of skin irritation is observed and recorded.  Upon completion of successful testing at the CDC, products can be registered for sale within China..  In


OnMay 25, 2007,the


anAgreement with Fuzhou Xinmei Biotech Co. Ltd. (Fuzhou), which allowed manufacturing and marketing in Fujian province in China(Exhibit 4.c.)

,was transferred to He-Yi She Ye Limited (He-Yi) and expanded to cover marketing in all of China.(Exhibit 4.g..).On August 31, 2006, He-Yi received its certificate of approval from the Fujian Centre of  Disease Control for T36®Disinfectant after passing all of the required tests. This certificate allowed He-Yi to apply to the Chinese National Centre for Health Inspection and Supervision for approval to manufacture T36®Disinfectant for sale in China and for export. The registration of T36®Disinfectant in China was expanded beyond disinfection of inanimate objects, such as hospital equipment and instruments, to also allow external use on humans, including use as a first-aid antiseptic and hand sanitizer. Approval for the manufacturing of T36®Disinfectant was obtained from the Ministry of Health in The Peoples Republic of China. On April 19, 2007, a manufacturing certificate (Certificate of Approval (Health ID. No. 0109) was granted to He-Yi for a period of four years from April 19, 2007 to April 18, 2011 and is renewable by filing an application for renewal 6 months before the expiry date. · The agreement with He-Yi provides that ALDA will provide He-Yi with all information that ALDA has at its disposal to assist with the registration of ALDAs products in China, He-Yi will be responsible for procuring all necessary government approvals for ALDAS products within 6 months from the time all technical data to support the application is provided by ALDA, quarterly reports on the progress of the approvals will be provided to ALDA by He-Yi, an extension may be requested by He-Yi to procure all necessary government approvals and may not be unreasonably refused by ALDA for recurring periods of 3 months if:  He-Yi is employing its best efforts in obtaining the registration of the ALDA products in China and is providing quarterly reports as required or more time is required by ALDA Pharmaceuticals Corp. to obtain information required by He-Yi,  ALDA Pharmaceuticals Corp. will provide He-Yi with the specifications required for He-Yi to provide a manufacturing facility suitable for the manufacturing of ALDAs products,  · He-Yi will provide a fully equipped manufacturing facility according to the specifications provided by ALDA, to produce the ALDA products subject to He-Yi employing its best efforts to obtain the space, materials and equipment specified by ALDA and He-Yi will have the right to distribute ALDAs products in China subject to ALDAs approval of each distributorship.  The Agreement is effective until April 18, 2011 (the Initial Term).  Upon expiration of the Initial Term, the Agreement may be renewed for additional periods, (the Renewals) provided that ALDA and He-Yi have each met all of their obligations under the Agreement and provided that He-Yi is able to obtain renewals of the Certificate of Approval (Health ID. No. 0109) that has been granted by the Ministry of Health of the Peoples Republic of China and expires on April 18, 2011. Any Renewals will reflect current market conditions in the territory served by He-Yi at the time the Renewals are granted and the time periods of any Renewals will be the same as the corresponding time periods of the renewals of the Certificate.  For the first 3 years after production is started by He-Yi and within 6 months after production is started by He-Yi, ALDA and He-Yi will establish minimum sales levels and, thereafter, after each new distributorship is established.  He-Yi will pay ALDA a royalty, based on the gross revenues received by He-Yi for all of ALDAs products sold in China as follows: · 5% during the first and second year after production is started by He-Yi, · 8% during the third year, · 6% after a doubling of sales over the sales achieved in the second year has occurred. · He-Yi will pay ALDA a 10% royalty based on the gross revenues received by He-Yi for all of ALDAs products sold by He-Yi outside of China. · All royalties will be paid monthly within 30 days after each month end.  ALDA, at ALDAs discretion, will have the right to buy product from He-Yi.  At the request of ALDA and with the authorization of ALDA, He-Yi agrees to direct ship ALDAs products for ALDA, at ALDAs expense, to anywhere in the world.  The Company cannot guarantee that He-Yi will be able to construct a manufacturing facility, that products manufactured by He-Yi will pass the quality control standards established by the Company or the Chinese government, that He-Yi will be able to obtain approvals to market the Companys products in other provinces of China or that He-Yi will be able to sell any of the Companys products at all in China or elsewhere.  2. Malaysia and Other Regions of Asia:

The Company has a 5 year licensing and distribution agreement with Linns Corporation Sdn Bhd (Linns) (see Exhibit 4.F.) with an effective date of August 1, 2004.  The Territory is defined as Brunei, Cambodia, Indonesia, Japan, Laos, Malaysia, Myanmar, Philippines, Singapore, South Korea, Taiwan, Thailand and Vietnam, subject to Linns submitting the required applications required for regulatory approval of T36®Disinfectant in each part of the Territory.  Alda Pharmaceuticals Corp. 2007 20F/A Page 24 
---------------------------------------------------------------------------------------------------------------------------------------------------------    Registration of T36®Disinfectant in Malaysia is being left to the discretion of the Linns because the Company is not knowledgeable about the registration requirements of jurisdictions outside of North America. On the Companys behalf, Linns submitted its T36®Disinfectant to the National Pharmaceutical Control Bureau, Ministry of Health, Malaysia and received approval in January of 2005 to sell T36®Disinfectant as a disinfectant, disinfectant cleaner sanitizer and deodorizer in Malaysia. However, because the T36® Disinfectant could be flammable, the Company needs approval from Malaysias Department of Fire & Rescue before T36®Disinfectant can be stored at Linns warehouse.  This approval has not yet been obtained. Linns is obliged to meet minimum sales levels that are mutually agreed upon by Linns and the Company and to purchase T36®Disinfectant from the Company. Linns has a Right of First Refusal to manufacture T36®Disinfectant for the Territory. If Linns meets the minimum sales obligations, the agreement is renewable for an additional 5 years. The termination provisions of the agreement are standard commercial terms that include uncorrected breaches of the agreement and any form of insolvency on the part of Linns or the Company. Seasonality The only seasonality observed with respect to T36® Disinfectant marketing is that sales slow down in the summer and during the Christmas period due to a general business slowdown as a result of customers being on holidays. Dependency upon Patents/Licenses/Contracts/Processes If the Company is able to further commercialize and increase sales of its T36®products, the Company may be dependent on patent and trademark protection to protect future potential revenues and growth.  Patents The Patent Cooperation Treaty (PCT) is an international patent law treaty established in 1970. It provides a unified procedure for filing patent applications to protect inventions in each of its Contracting States, which includes each jurisdiction specified below. A patent application filed under the PCT is called an international application or PCT application. A single filing of an international application is made with a Receiving Office (RO) in one language. It then results in a search being performed by an International Searching Authority (ISA), accompanied with a written opinion regarding the patentability of the invention which is the subject of the application. Optionally, this is followed by a preliminary examination, performed by an International Preliminary Examining Authority (IPEA). The PCT does not lead to the grant of an "international patent", which does not exist, but rather, national patent examinations that are handled by each relevant national or regional authority. For example, in Canada, the US, China, Australia and Singapore, there are national patent offices whereas, in Europe, the European Patent Office handles the national phase for its member states.  API filed patent application #PCT/CA2002/001284, A wide spectrum disinfectant, on August 20, 2002. All rights to the patent application were transferred from API to the Company on completion of the Qualifying Transaction on November 13, 2003. A summary of subsequent events is presented below. Canada: On February 18, 2005 the Canadian Intellectual Property Office received the PCT patent application and assigned it Patent Application Number 2,495,938. European Union: On March 30, 2005 the PCT application was accepted for national examination by the European Patent Office (EPO) and assigned it Patent Application Number 02754054.1-2113. The countries covered by the European patent application are Austria, Belgium, Bulgaria, Switzerland, Cyprus, the Czech Republic, Germany, Denmark, Estonia, Spain, Finland, France, Great Britain (the UK), Greece, Ireland, Italy, Liechtenstein, Luxembourg, Monaco, Netherlands, Portugal, Sweden, the Slovak Republic and Turkey. On May 18, 2005, the bibliographic data of the above-noted application was published in the European Patent Bulletin, under Publication No. 1530485. The resulting effect of such publication is that any possible infringer is deemed to have knowledge of the patent application without the Company having to formally inform them of this applications existence. On October 18, 2006 the EPO provided the Company with an Office Action requesting further information on the patent application. The Company responded to the questions and received a second Office Action, dated September 5, 2007 from the EPO. This second Office Action requested that the Company provide certain additional information to support the claims that were made in the application. China: On June 25, 2005 the Company was notified that the PCT application was accepted for national examination by the Patent Office of the Peoples Republic or China (Chinese Patent Office) and assigned Patent Application Number 02829642.7. On August 11, 2005, the Chinese Patent Office accepted a Request for Substantive Examination from the Company. The application was published in the Chinese Patent Gazette on October 19, 2005, under Publication No. CN1684711A and entered into Substantive Examination. On February 5, 2006, the Company filed a Voluntary Amendment to the original patent application to correct certain minor errors in the original application. On June 2, 2006, the Chinese Patent Office provided an Office Action which requested certain additional amendments to the patent application. On December 18, 2006, the Company filed its response to the Office Action. The Company was notified by the Chinese Patent Office that the Chinese patent had been allowed, effective June 8, 2007.  Alda Pharmaceuticals Corp. 2007 20F/A Page 25 
---------------------------------------------------------------------------------------------------------------------------------------------------------    United States: On February 18, 2005, the US Patent and Trademark Office (USPTO) received the PCT patent application and assigned it Patent Application Number 10/525,110. The patent application was published by the USPTO on December 22, 2005, under Publication Number US 2005/0282727. On July 27, 2006, the Company received that first Office Action from the USPTO which required clarification or modification of certain claims made in the patent application. The Company was required to respond to the Office Action by October 27, 2006 and did so on October 26, 2006 with amendments to the claims that required clarification or modification. On February 7, 2007 the USPTO provided the Company with a Notice of Allowance for the US patent with all claims made by the Company accepted  by the USPTO. A Notice of Allowance is not a grant of a patent and is subject to withdrawal by the USPTO or on petition by the Company. The Company then filed certain minor, voluntary amendments to the patent application and a second Notice of Allowance, dated June 8, 2007 was provided by the USPTO.   Singapore:On February 18, 2005, the Singapore Patent Office accepted the PCT patent application and assigned it Patent Application Number 200500987-3. Australia: On March 15, 2005 the PCT application was accepted for national examination by the Australian patent office on March 15, 2005 and assigned with Patent Application Number 2002322916. On October 24, 2006, the Australian patent office provided the Company with a Direction to Request Examination. Under Australian Patent law, such examination must be requested within five years of the filing date or within six months of receiving a direction from the Australian Patent Office, whichever is sooner.  The subject matter of all of these pending patents is the composition of T36®Disinfectant which contains five active ingredients, four of which are in relatively low concentrations that act synergistically to disrupt the physical structure of all types of micro-organisms. The pending patents also provide for the method of manufacturing T36®Disinfectant. As of June 30, 2007 none of these patents has yet been finally granted.  The Company cannot estimate when, if at all, the patents will be granted. Trademarks: The Company successfully trademarked T36 in Canada on April 22, 2004 and in the United States on November 2, 2004.  The trademark in the United States is a Principal Register mark. The Principal Register of the US Patent and Trademark Office (USPTO) conveys the important substantive rights that most people associate with federal registration and, as a result, it is the preferred method of federal trademark protection. Probably the most important benefit of placing a mark on the Principal Register is that anybody who later initiates use of the same or a confusingly similar trademark may be presumed by the courts to be a "willful infringer" and therefore liable for damages. The Company also successfully trademarked the Companys logo in Canada on July 16, 2004 and in the United States on January 18, 2005, also as a Principal Register mark. Impairment of intellectual property The Company purchased

, at an estimated cost of $540,000,

 substantially all of the assets and undertakings of API, principally comprised of certain intellectual property rights of API related to T36 Disinfectant developed by API including certain drug identification numbers, trademark and patent applications, inventory, capital assets, the shares of ALDA Institute For Preventative Health Care Inc., a non-competition agreement, and certain contracts. The value placed on these assets was $540,000.In the financial statements, the intangible assets balance represents the carrying amount for the intellectual property and these assets were determined to have an indefinite life. An impairment loss of $179,000 was charged against earnings for fiscal 2004 and an impairment loss of $245,000 was charged against earnings for fiscal 2005. This impairment loss was considered necessary due to sales of the T36®Disinfectant being lower than the $540,000 valuation could support and also because the Company's progress towards securing legal protections for its proprietary product and development of a market for its product were significantly slower than had been anticipated at the time of the purchase of the business assets.  At June 30, 2005, the carrying cost of the intangible assets was written down to the estimated net recoverable amount of $116,000.  Alda Pharmaceuticals Corp. 2007 20F/A Page 26 
---------------------------------------------------------------------------------------------------------------------------------------------------------    The carrying amount of Intangible Assets was determined as follows: Original purchase cost (Note 9) $540,000 Impairment loss in 2004 (179,000) Balance at June 30, 2004 361,000 Impairment loss in 2005 (245,000) Balance at June 30, 2005 116,000 Balance at June 30, 2006 $116,000  Effective July 1, 2006, the Company changed its estimate of the useful life of the intangible assets from an infinite life to a finite of 20 years.  The impact of this change in estimate was to increase amortization by $5,800 for the year ended June 30, 2007. Opening balance as at July 1, 2006 $116,000 Accumulated amortization (   5,800) Balance as at June 30, 2007 $110,200  Sources/Availability of Raw Materials and Production T36®is comprised of ethanol, o-phenyl phenol, benzalkonium chloride and other ingredients, including lemon fragrance and water.  All of these chemical raw materials are commonly produced in industrialized countries by a number of manufacturers and are generally considered safe to transport. However, they have a low value to weight ratio which means it is likely cheaper to source raw materials from local producers than shipping raw materials from other markets. As a result, the Company does not believe that it is vulnerable to raw materials shortages or to loss of access to supply from any one producer. The Company has entered into a production contract with Norwood Packaging Ltd. (see Exhibit 4.Bb) and anticipates entering into production contracts for each area in which the Company would market and sell the T36®Disinfectant or other products. The Company does not have production facilities or anticipate leasing, building or acquiring production facilities. Principal markets and Potential Product Markets At this time, the Companys sales have principally been to: 1. First Responder organizations, including ambulance, fire fighters and police forces in Canada; 2. Dental clinics; and 3. Beauty and hair care salons and spas. There are no reliable market estimates of the size of the disinfectant or disinfectant cleaner market in these segments. The Company hopes to expand its product sales to hospital and related consumers in the future. In addition, the Company hopes to expand its product sales to the United States and China.  However, as detailed in Item 4B Material Effects of Government Regulation, the Companys products must first receive regulatory approval in any new sales jurisdiction and obtaining this approval can be costly and time consuming. There is no available estimate of the size of the Canadian market for disinfectant products or products similar to those of the Company. Also, no estimates are available for the US or overseas markets. Disinfectant Products are a very broad category of products and, where estimates are available of market size, the data appears to include many products dissimilar to those of the Company and often includes consumer products (e.g. widely marketed consumer brand name hand soaps).  As well, particularly in the market niches where the Companys sales have been to date (as described above), there are a number of private company producers of disinfectant products whose sales figures are not publicly available.  No industry trade organization exists which could provide estimates of disinfectant sales, in product categories, for Canada or the United States.  Alda Pharmaceuticals Corp. 2007 20F/A Page 27 
---------------------------------------------------------------------------------------------------------------------------------------------------------    Marketing, Distribution and Sales Channels The Company does not directly market its products to end consumers.  The Companys marketing, distribution and sales model is to market its products to wholesalers of similar products who then market the products to end consumers. The wholesale industry for disinfectants, cleaners, cleaning and hospital supplies and similar consumer products is fragmented into a large number of wholesalers.  As a result, no competitor of the Company exercises significant control over distribution.  However, the Company must convince each new wholesaler that it targets both to carry its products, often in place of other existing products, and also to make the Companys products available to the wholesalers customers. The Companys products and name are not immediately recognizable to end consumers and, as a result, wholesalers have to make some additional effort to generate sales, as compared to the effort associated with a product familiar to end consumers. This difficulty, which all new companies face in marketing their products, is probably the greatest challenge for the Company (i.e. how to get end consumers to recognize and request its products from wholesalers), given the Companys limited budget for incentives or advertising. The Company markets it products to wholesalers through one inside sales and marketing representative, trade shows, lectures to end users and product promotional materials and flyers. The current key accounts are



described below. With one exception, there are no contracts or oral agreements in place. Customers and distributors place orders for products from the Company, the shipper receives instructions from the Company and the shipper sends the products from its warehouse via carriers specified by the Company or the customer. All product shipments are made FOB from the Companys shipper and title passes to the customer upon the Companys or customers carrier taking delivery of the product from the shipper.  The Company may prepay all costs of transportation and insurance and the customer reimburses the Company for such expenses.  The payment terms for products delivered to the customer by the Company are net cash in Canadian currency within 30 days. 1. Esthetics Plus, Inc.

The Company currently sells its T36® Disinfectant through these distributors and is also planning on introducing its new products, such as the T36® "Ready to Use" Disinfectant Cleaner, T36® Disinfectant Cleaner CONCENTRATE and the corresponding wipes, through these distributors. The current sales and plans to introduce the new products through these distributors would be disrupted if any of these distributors stopped representing the Company. The result would be a reduction in the Companys revenues until new distributors could be found. It is possible that new distributors might not be found and the Company would have to try to sell its products directly to the end users, leading to a significant increase in marketing and sales costs, even if the sales levels could be regained. 4.C.  Organization structure The Company is not part of a group and has only one wholly owned subsidiary, Sirona Therapeutics Corp. (Sirona), formerly the ALDA Institute for Preventative Health Care Inc., a Company incorporated in British Columbia. On January 12, 2005 the Company entered into a license agreement with



Sirona.  Under this agreement, the Company can choose to transfer the rights to certain therapeutic applications of its T36®Disinfectant to Sirona if financing is directed into Sirona rather then into the Company. The Company will retain ownership of the technologies if Sirona undertakes any financing and completes the patenting and registration of any therapeutic products developed and based on the T36®Disinfectant. At the present time, Sirona is an inactive company, but is in a position to become active if Sirona secures investment funding in the future. If such an investment is not made directly into Sirona, it will remain inactive or may undertake unrelated business activities.  Alda Pharmaceuticals Corp. 2007 20F/A Page 28

Property, Plant and Equipment The Company has executive offices at 635 Columbia Street, New Westminster, British Columbia, V3M 1A7 which consist of 1,975 square feet. The Company leases its offices on a month-by-month basis at CDN$ 2,401.98 per month (see Exhibit 4.Dd. for original lease agreement). The Company contracts out its manufacturing and has no present intention of leasing or acquiring manufacturing facilities (see Exhibit 4.Bb. for production contract with Norwood Packaging Ltd.). Item 4A Unresolved Staff Comments No disclosure necessary. ITEM 5.  OPERATING AND FINANCIAL REVIEW AND PROSPECTS This discussion should be read in conjunction with the audited financial statements of the Company and related notes included therein. 5.A.  Operating Results of The Company Overview Over the course of the Companys operating history, the Company has successfully secured the required government and regulatory approvals to market and sell its T36®Disinfectant products in Canada.  This has resulted in sales as described in Results of Operations below and, to date, all of the Companys sales have been in Canada. Canada, however, while it is a developed industrial economy, is not a particularly large market relative to economies such as the United States or China. To achieve profitability and increase sales substantially, the Company must first secure government and regulatory approval of its products in markets outside of Canada or secure registrations for additional products within Canada Although sales in Canada have grown over the Companys operating history, the Company has not yet secured the required government and regulatory approvals for the sales of its products outside of Canada.  Each government or regulatory jurisdiction tends to require efficacy studies or safety studies of differing content or quality.  The regulatory approval process to date has been costly both in terms of working capital and in terms of management time and attention. Results of Operations The Company has been actively marketing its T36®Disinfectant product since the acquisition of API was completed. The Companys sales, over the last three financial years, have been$239,271 in the year ended in June, 2005, $223,586 in the year ended June 30, 2006 and $256,243 in the year ended June 30, 2007.  The unit cost of sales has stabilized as a percentage of sales in the years ended June, 2006 and 2007. However, the Company is still operating overall with a significant loss from operations.  This reflects, to a great extent, the costs associated with trying to register its products for sale in jurisdictions other than Canada and ongoing administrative, management and intellectual property protection costs. To generate a net profit, the Company believes that it must register its products for sale in another major market, such as the United States or China or both, to achieve sales economies or achieve significant sales of its newer products such as the hand sanitizer and disinfectant cleaners. Sales For the year ended June 30, 2007, sales were $256,342 compared to $223,586 for the year ended on June 30, 2006, and $239,271 for the year ended on June 30, 2005. Sales were generated in 2005, 2006 and 2007 from the Companys surface disinfectant, T36® Disinfectant, through its distributors to the first responders, dental and beauty markets.  In 2006, the Company introduced the T36® Hand Sanitizer, which is also being sold through the same distributors.  Alda Pharmaceuticals Corp. 2007 20F/A Page 29 
---------------------------------------------------------------------------------------------------------------------------------------------------------    Some seasonality is observed with sales slowing down in the summer and over the Christmas period. No other factors seem to significantly affect sales on a quarterly basis. No new competitors have appeared in the market nor have any withdrawn from the market. Company Average Monthly Sales for the year ended June 30, 2007 were $ 21,353 compared to $18,632 per month for the year ended June 30, 2006



and $19,939 per month for the year ended June 30, 2005. The 7%



drop in average sales in 2006 compared to 2005 was likely due to the timing of purchases bycustomers and the 15% increase in average



sales per month overin



2007 compared to 2006 was likely



due to the timingof purchases and the



addition of a Hand Sanitizer to the product line. Cost of Sales The cost of sales for the year ended June 30, 2007 was $165,920 compared to $142,379 for the year ended on June 30, 2006, and $150,075 for the year ended on June 30, 2005. Cost of sales includes the direct costs of the inventory sold during the period plus warehousing costs and handling charges. Gross Profit (Loss) In 2007, a gross profit of $90,323 was retained, which was in line with the gross profit of $81,207 in 2006 and $89,196 in 2005. Advertising and Promotion Advertising and promotion costs for the year ended June 30, 2007 were $12,766 compared to $12,169 and $27,685 for the year ended June 30, 2006 and



2005, respectively. Costs in this category were reduced significantly as the Company did not allocate as muchmany resources to



advertising in 2006 and 2007



as in the 2005



fiscal year

s

..  The Company has put new efforts into attracting new customers by providing lectures, sending samples of T36® Disinfectant and literature to potential new customers and distributors



rather than paying for journal advertising. Amortization In 2007, patent costs incurred during the year were capitalized with an amortization period of 20 years resulting in $2,131 in amortization expense being recognized.  In addition, the Company changed its estimate of the useful life of the intangible assets from an infinite life to a finite life of 20 years; as a result of such change, amortization of $5,800 was recognized in the statements of operations and deficit.  Amortization of $8,217 for the year ended June, 2005, $8,281 for the year ended June, 2006 and $8,350 for the year ended June, 2007 were being recognized. Conferences Expenses for conferences were $12,035 for the year ended June, 2005

.. Consulting & Management Services Fees Consulting fees for the year ended June 30, 2007 were $308,600 as compared to $183,218, and $210,561 for the year ended June 30, 2006, and 2005



respectively.  The consulting fees primarily represent remuneration for management services provided to the Company by management services companies controlled by the Companys President, Terrance Owen; its CFO and Peter Chen. The consulting fees were higher for the fiscal year ended June 30, 2007 because




 

of increased product registration activities compared to 2005 and 2006 and




of

$82,000 of



stock-based compensation expenses being recognized in this category2007 from the issuance of 3,530,000 stock options to consultants officers, directors and employees in 2007.compared to 300,000 options granted in 2005 and no options granted in 2006.. Filing Fees Filing fees were $21,544 for the year ended June, 2005, $22,834 for the year ended June, 2006 and $24,570 for the year ended June, 2007 due to the need for the Company to pay the regulatory bodies for such matters as the completion of private placements, the issuance of options, the filing of financial documents and the payment of annual listing fees. Investor Relations Investor relations costs were $90,779 for the year ended June



30, 2005, decreased to



$52,808 for the year ended June 30,

---------------------------------------------------------------------------------------------------------------------------------------------------------    Legal and Accounting Legal and accounting was $57,833 for the year ended June, 2005, $63,178 for the year ended June 30, 2006 and $53,697 for the year ended June 30, 2007. Accounting fees consist primarily of the cost of the year-end audits and for reviewing the quarterly statements. As announced in a news release issued by the Company on September 13, 2007, Berris Mangan resigned as the Companys external auditor due to a decision by Berris Mangan to focus its practice on TSX-listed companies with Canadian reporting responsibilities.  The Company appointed HLB Cinnamon Jang Willoughby, Charted Accountant (CJW) to conduct the year-end audit.   Legal fees included costs for preparing materials for the AGM, closing of a private placement by way of an Offering Memorandum, preparing the agreement between the Company and JohnsonDiversey, Inc. that settled the trademark dispute as announced in a press release dated May 30, 2005 and continuing legal action seeking damages from a competitor as announced in a news release issued by the Company on June 30, 2004. In the 2004 fiscal year, legal costs were incurred for closing the Qualifying Transaction, the Financing associated with the Qualifying Transaction, required regulatory filings and litigation involving a competitor as announced in new releases issued by the Company on May 14, 2004 and June 30, 2005. Office and Miscellaneous Office and Miscellaneous expenses were $30,426 for the year ended June, 2005, $25,450 for the year ended June, 2006 and $24,008 for the year ended June, 2007 due to the need for the Company to undertake sales of its acquired product and to maintain its administrative functions for day-to-day operations.



Office and miscellaneous expenses have steadily declined due to greater efficiency and fewer purchases of office supplies after the initial need to stock up on such supplies. Product Development and Product Registration Costs in these two categories are combined for purposes of this discussion. Costs in this category were $54,293 for the year ended June, 2005 and $18,377 for June 30, 2006.  In 2007, total costs incurred in this category were $42,617 and capitalized under patent application and development costs. Patent costs incurred during the year were capitalized with an amortization period of 20 years rather than expensed.  A new category has been added to the Balance Sheet to reflect this change in accounting practices.  Costs in this category include the fees paid to the regulatory consultants in Canada and the US to pursue the registration of the Companys products in the United Kingdom and the United States. Costs spent on laboratory testing and intellectual property protection are also included in this category. Product registration refers to the registration of the Companys products with Health Canada and to the patenting activities undertaken by the Company. The level of these activities varies from year to year as funds become available from external sources and may not be consisten

t. Rent Rent was $25,265 for the year ended June, 2005, $30,912 for the year ended June, 2006 and $28,371 for the year ended June, 2007. Travel Travel expenses were, $4,512 for the year ended June, 2005, $3,252 for the year ended June, 2006 and $10,259 for the year ended June, 2007

..

The travel expenses were higher in 2007 due to the President & CEO of the Company attending meetings arranged by RAMP in Europe for the purpose of raising funds

..


due to the need for the Company to attend conferences to achieve sales of its products

.. Wages and Benefits Wages and benefits were $97,389 for the year ended June, 2005, $75,903 for the year ended June, 2006 and $116,633 for the year ended June, 2007. Costs in this category include the wages paid for accounting and administrative assistance.  Expenses were higher for the year ended June, 2007 because of the stock-based compensation expense of $62,500



as result of 3,530,000 stock options to consultants officers, directors and employees..

. Loss from Operations The loss from operations was $562,090 as compared to $380,026 for the year end June 30, 2006, and $553,028 for the year ended June 30, 2005. The losses were due, in large part, not due to a loss on sales (see Gross Profit (Loss) above) but to the many costs incurred to establish a basis for further growth of the Company, such as costs associated with patenting the Companys products, costs associated with attempting to secure US and foreign regulatory approval of the Companys products and producing prototypes of products (such as disinfectant wipes, which contain the Companys T36®Disinfectant or similar active ingredients).  The loss for the year ended June 2007 was higher than June, 2007 because of the non-cash stock-based compensation expense of $148,100.  Alda Pharmaceuticals Corp. 2007 20F/A Page 31 
---------------------------------------------------------------------------------------------------------------------------------------------------------    Other Income (Loss) Under this category, the impairment loss on intangible assets and the loss on legal settlement have been described elsewhere. 5.B. Liquidity and capital resources The Company had working capital of approximately $627,730 as of June 30, 2007.  As described

in ITEM 4.B. Plan of Operations




below, the Company believes that it requires $337,270 in additional working capital to complete its planned business activities over the 18 month period ending

with the end of its Fiscal 2008

on December 31, 2008.  Source of Funds for Fiscal 2008 and for Fiscal 2009 The Companys primary source of funds since incorporation has been and continues to be through the issuance of common shares since sales revenues are not yet rising. As of June 30, 2007, the Company had a deficit of $2,603,791

..  Use of Funds for Fiscal 2008/2009 For the 18 months ending December 31, 2008 the Company estimates that it will require the following to fund planned operations

:  General Office and Administrative Expenses: $   700,000 New Products Research and Development: $   100,000 US securities fees and expenses (related to Form 20F filing): $     30,000 Sales and Marketing: $   235,000 Patenting activities: $     30,000 Regulatory activities (1): $   150,000 New Product Sample Inventory / Production (2): $     20,000 Total: $1,265,000 Less Anticipated Revenue: $   300,000 Additional Funds required: $   965,000 Working Capital (as of June 30, 2007): $   627,730 TOTAL ADDITIONAL FUNDS REQUIRED: $   337,270  (1) Regulatory Activities refers to performance of toxicology, efficacy and other studies required to secure FDA, EPA and other regulatory approvals so that the Company can sell in markets outside of Canada and also refer to securing Health Canada Drug Identification Numbers for Canadian approvals for the Companys new products. (2) New Product Sample Inventory / Production refers to the costs of producing samples for market and consumer testing of those products the Company is developing.  It is the intention of management to undertake private placements as needed to secure sufficient working capital to maintain its operational and development plans. For example, the Company closed a brokered private placement of 8,000,000 Units of the Company at a price per share of $0.10 for gross proceeds of $800,000 as announced on June 7, 2007. Management will undertake further such private placements as required. While the Company has (as described above in Results of Operations) experienced sales revenues growth, these revenues are not sufficient, at this time, to enable the Company to expand its activities in seeking regulatory approval in markets outside of Canada or to enable it to develop and market new products. If it is unable to secure additional equity financing, the Company may not be able to continue as an operating business.  The Company is operating at a loss and its sales revenues do not currently cover even its general and administrative expenses. Critical Accounting Policies Please refer to the Notes to the audited financial statements Recent Accounting Pronouncements  1. Stock-based compensation Effective July 1, 2001, the Company adopted the new recommendations of the Canadian Institute of Chartered Accountants Accounting Handbook Section 3870, Stock-based Compensation and Other Stock-based Payments ("CICA 3870").  The new recommendations were applied prospectively to all stock-based payments to employees and non-employees granted on or after July 1, 2001.  Alda Pharmaceuticals Corp. 2007 20F/A Page 32 
---------------------------------------------------------------------------------------------------------------------------------------------------------    Under CICA 3870, prior to July 1, 2003, the Company was not required to record compensation expense for stock-based compensation awards granted to employees, except for employee awards that were direct awards of stock, called for settlement in cash or other assets, or were stock appreciation rights that called for settlement by the issuance of equity instruments.  Consequently the adoption of the standard had no impact on the figures presented other than the pro forma disclosure contained in Note 8(d). During the year ended June 30, 2004, CICA 3870 was amended to require the use of the fair value-based method to account for stock options granted to employees.  In accordance with the revised recommendations, the Company has prospectively applied the fair value-based method to all stock options granted to employees on or after July 1, 2003, whereby compensation cost is measured at fair value at the date of grant and is expensed over the vesting period. 2. Impairment of long-lived assets Effective July 1, 2003, the Company adopted the recommendations of the Canadian Institute of Chartered Accountants Handbook Section 3063, Impairment of long-lived assets.  The new recommendations were applied prospectively to all long-lived assets held for use by the Company after July 1, 2003. 5.C.  Research and development, patents and licenses etc. The Company expects to spend approximately $100,000 on research and development of its products in Fiscal 2008 in total.  Some of these funds will, it is anticipated, by expended in preparing submissions to the FDA and the EPA under the Phigenics, LLC contract (see Exhibit 4.

A


a

..) which provides that Phigenics will seek FDA and EPA approval of the Companys products. Because it is impossible to predict if the EPA or FDA will request further studies or reviews of the Companys products, or what cost such studies or reviews would incur, it is not possible to say if this budget will suffice to allow Phigenics to complete submissions on the Companys behalf. The Company does not presently have the working capital to fund its Research and Development expenditures described above and will need to undertake further financings to secure the funds required.. 5.D.   Trend information There are no markets or other trends, other than as disclosed below, which the Company believes materially affect its business prospects. The Companys existing customers and the general public are becoming more aware of disinfectant products. The continuing spread of antibiotic resistant bacteria is contributing to this awareness and a perception that there is a growing need or demand for products similar to those the Company produces. This has resulted in growth in the market for disinfectant products, in particular consumer products which provide antibacterial soaps and lotions.  No reliable quantification of the growth these product sales have experienced is available and no growth or future growth can be reliably predicted. The Company believes that the demand for its T36®Disinfectant product, or at least for similar products, will increase. 5.E.  Off-balance sheet arrangements The Company does not have any off-balance sheet arrangements. 5.F.  Tabular disclosure of contractual obligations The Company does not have any long-term debt obligations, capital (finance) lease obligations, operating lease obligations, purchase obligations or other long-term liabilities reflected on the Companys balance sheet. 5.G.  Safe Harbor This Annual Report on Form 20-F contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, principally in ITEM #4, Information on the Company and ITEM #5.  These statements may be identified by the use of words like plan, expect, aim, believe, project, anticipate, intend, estimate, will, should, could and similar expressions in connection with any discussion, expectation, or projection of future operating or financial performance, events or trends.

The Company adopted a formal written stock option plan (the "Plan") on December 13, 2005. (A copy of the Companys Stock Option Plan is included with this document as Exhibit 4.Ee.)At every Annual General Meeting of the Company, the Plan is presented to and voted on by the shareholders of the Company. If approved, the terms and conditions of the Plan remain in force for the subsequent year.  Alda Pharmaceuticals Corp. 2007 20F/A Page 38 
---------------------------------------------------------------------------------------------------------------------------------------------------------    Such terms and conditions, including the pricing of the options, expiry and the eligibility of personnel for such stock options; and are described below. The principal purposes of the Companys stock option program are to (a) assist the Company in attracting, retaining, and motivating directors, officers and employees of the Company and, (b) to closely align the personal interests of such directors, officers and employees with the interests of the Company and its shareholders. The Plan provides that stock options may be granted to service providers for the Company.

For stock options to Employees, Consultants or Management Company Employees, the Company must represent that the optionee is a bona fide Employee, Consultant or Management Company Employee as the case may be.  The terms insider Controlled and subsidiary shall have the meanings ascribed thereto in the Securities Act (Ontario) from time to time.  Subject to the foregoing, the board of directors or Committee, as applicable, shall have full and final authority to determine the persons who are to be granted options under the Plan and the number of shares subject to each option. The Plan shall be administered by the board of directors of the Company or a committee established by the board of directors for that purpose.  Subject to approval of the granting of options by the board of directors or Committee, as applicable, the Company shall grant options under the Plan. The Plan provides that the aggregate number of shares of the Company, which may be issued and sold under the Plan, will not exceed 10% of the issued shares of the Company.  The Company shall not, upon the exercise of any option, be required to issue or deliver any shares prior to (a) the admission of such shares to listing on any stock exchange on which the Companys shares may them be listed, and (b) the completion of such registration or other qualification of such shares under any law, rules or regulation as the Company shall determine to be necessary or advisable.  If any shares cannot be issued to any optionee for whatever reason, the obligation of the Company to issue such shares shall terminate and any option exercise price paid to the Company shall be returned to the optionee. If a stock option expires or otherwise terminates for any reason without having been exercised in full, the number of common shares reserved for issuance under that expired or terminated stock option shall again be available for the purposes of the Plan.  Any stock option outstanding when the Plan is terminated will remain in effect until it is exercised or it expires.  The Plan provides that it is solely within the discretion of the Board to determine who should receive stock options and in what amounts, subject to the following conditions: (a) Options will be non-assignable and non-transferable except that they will be exercisable by the personal representative of the option holder in the event of the option holders death; (b) Options may be exercisable for a maximum of five years from grant date; (c) Options to acquire no more than 5% of the issued shares of the Company may be granted to any one individual in any 12-month period; (d) Options to acquire no more than 2% of the issued shares of the Company may be granted to any one consultant in any 12-month period; (e) Options to acquire no more than an aggregate of 2% of the issued shares of  the Company may be granted to an employee conducting investor relations activities (as defined in TSX Venture Exchange Policy 1.1), in any 12 month period; (f) Options to acquire no more than 10% of the issued shares of the Company may be granted to any insiders in any 12-month period;  Alda Pharmaceuticals Corp. 2007 20F/A Page 39 
---------------------------------------------------------------------------------------------------------------------------------------------------------    (g) Options held by an option holder who is a director, employee, consultant or management company employee must expire within 90 days after the option holder ceases to be a director, employee, consultant or management company employee; (h) Options held by an option holder who is engaged in investor relations activities must expire within 30 days after the option holder ceases to be employed by the Company to provide investor relations activities; and (i) In the event of an option holders death, the option holders personal representative may exercise any portion of the option holders vested outstanding options for a period of one year following the option holders death. The Plan provides that other terms and conditions may be attached to a particular stock option, such terms and conditions to be referred to in a schedule attached to the option certificate.  Stock options granted to directors, senior officers, employees or consultants will vest when granted unless otherwise determined by the Board on a case by case basis, other than stock options granted to consultants performing investor relations activities, which will vest in stages over 12 months with no more than one-fourth of the options vesting in any three month period. The price at which an option holder may purchase a common share upon the exercise of a stock option will be as set forth in the option certificate issued in respect of such option and in any event will not be less than the discounted market price of the Companys common shares as of the date of the grant of the stock option (the Award Date).  The market price of the Companys common shares for a particular Award Date will typically be the closing trading price of the Companys common shares on the day immediately preceding the Award Date, or otherwise in accordance with the terms of the Plan.  Where there is no such closing price or trade on the prior trading day market price shall mean the average of the most recent bid and ask of the shares of the Company on any stock exchange on which the shares are listed or dealing network on which the shares of the Company trade. In no case will a stock option be exercisable at a price less than the minimum prescribed by each of the organized trading facilities or the applicable regulatory authorities that would apply to the award of the stock option in question. Common shares will not be issued pursuant to stock options granted under the Plan until they have been fully paid for by the option holder.  The Company will not provide financial assistance or loans to option holders to assist them in exercising their stock options.

..   8.A.7.  Legal/Arbitration Proceedings The Directors and the management of the Company do not know of any material, active or pending, legal proceedings against them; nor is the Company involved as a plaintiff in any material proceeding or pending litigation, other than as described below: On May 14, 2004, the Company announced that certain documents which had been published and disseminated by CIBRON Corporation, a company which had been retained by the Company as a   manufacturers representative, together with presentation materials presented at a conference by a consultant to the Company contained certain comparisons and information with respect to the safety and efficacy of products manufactured and sold by Virox Technologies Inc. that were untrue, and potentially misleading in the context in which they were presented. On June 14, 2004, the Company received a release from Virox Technologies, Inc. and paid an amount of $10,000 to settle a legal claim made by Virox Technologies, Inc. Subsequently On June 18, 2004, the management of the Company discovered that Virox had posted damaging, misleading, libelous and possibly fraudulent statements on Viroxs website about the Company. The Company also suspected that Virox had infringed on the Companys trademark and copyright. The Company filed an action (No. S043563) for defamation in the Vancouver Court Registry of the Province of British Columbia on June 25, 2004., naming the defendants as Virox Technologies Inc. and one of its principals, Randy Pilon. This claim was settled effective July 12, 2006, by an agreement under which the Company received an amount of $15,000 from the competitor. The proceeds of the settlement, net of associated legal costs in the amount of $4,455, have been recognized in the Statement of Operations and Deficit for the period ended June 30, 2007.  ..


No trial date has been set for this action as of yet.  The Company has filed an offer for settlement for Cdn $10,000 plus costs which is outstanding. Prior to the completion of the Qualifying Transaction, a company, JohnsonDiversey Inc., opposed a trademark application made in Canada by API and commenced legal proceedings during 2003 claiming damages in respect to alleged infringement of trademark. API had filed a Statement of Defence prior to the completion of the Qualifying Transaction. The Statement of Claim was subsequently amended to add the Company as a defendant in the action. On May 23, 2005, the Company entered into a settlement agreement with that company, whereby the Company agreed to terminate the use, and application for registration of, the trademark "Viralex". The Company must discontinue the use of that trademark in advertising and other promotional disclosures, liquidate its inventory of goods bearing the trademark "Viralex", and rename the Viralex product within twelve months from the date of the agreement, in consideration for payment of $30,000 (US). These funds were held in escrow by the Company's lawyer until the Company issued a press release regarding the settlement of the trademark dispute, and withdrew its application for the "Viralex" trademark, which occurred on May 30, 2005. The proceeds of the settlement, net of associated costs, as well as the costs associated with establishment of a new trademark, are recognized for accounting purposes in the 2006 year, when the Company's obligations under the settlement agreement are fulfilled. The Company has since renamed its lead product and it is now referred to as T36® Disinfectant The Directors and the management of the Company know of no active or pending proceedings against anyone that might materially adversely affect an interest of the Company.  8.B.

the Company

sinitial registration statement on Form 20-F.  The following is a summary of certain  provisions of the Company's  Notice of Articles and Articles and certain provisions of the British Columbia Business Corporations Act (the BCA), applicable to the Company: Objects and Purposes The Articles do not specify objects or purposes.  Under both the BCA, a British Columbia corporation generally has all the legal powers of a natural person.  British Columbia corporations may not undertake certain limited business activities such as operating as a trust company or railroad without alterations to its form of articles and specific government consent. Share Capital The authorized capital of the Company consists of an unlimited number of common shares without par value.  All of the common shares must be fully paid and are not subject to any future call or assessment.  All of the common shares of the Company rank equally as to voting rights, participation in a distribution of the assets of the Company on a liquidation, dissolution or winding-up of the Company and the entitlement to dividends.  The holders of the common shares are entitled to receive notice of all shareholder meetings and to attend and vote at such meetings.  Shareholders are not entitled to cumulative voting.  Each common share carries with it the right to one vote.  The common shares do not have preemptive or conversion rights.  In addition, there are no sinking fund or redemption provisions applicable to the common shares or any provisions discriminating against any existing or prospective holders of such securities as a result of a shareholder owning a substantial number of shares. Share Certificates Under the Articles, a shareholder is entitled to a share certificate representing the number of shares of the Company held or a written acknowledgement of the shareholders right to obtain such a share certificate.

.. Dividends Dividends may be declared by the Board out of available assets and are paid rateably to holders of common shares.  No dividend may be paid if ALDA


the Company is, or would thereby become, insolvent.  Alda Pharmaceuticals Corp. 2007 20F/A Page 48 
---------------------------------------------------------------------------------------------------------------------------------------------------------    Voting Rights Each ALDAof the Companyscommon share is entitled to one vote on matters to which common shares ordinarily vote including the annual election of directors, appointment of auditors and approval of corporate changes.  There are no cumulative voting rights applicable to ALDAthe Company. Borrowing Powers The Company, if authorized by the directors, may: (a) borrow money in the manner and amount, on the security, from the sources and on the terms and conditions that they consider appropriate; (b) issue bonds, debentures and other debt obligations either outright or as security for any liability or obligation of the Company or any other person and at such discounts or premiums and on such other terms as they consider appropriate; (c) guarantee the repayment of money by any other person or the performance of any obligation of any other person; and (d)mortgage, charge, whether by way of specific or floating charge, grant a security interest in, or give other security on, the whole or any part of the present and future assets and undertaking of the Company. Indemnity Provisions Under the Articles and the BCA, the Company is now permitted (and is, in some circumstances, required) to indemnify a past or present director or officer of the Company or an associated corporation without obtaining prior court approval in respect of an eligible proceeding. An eligible proceeding includes any legal proceeding relating to the activities of the individual as a director or officer of the Company. However, under the BCA, the Company will be prohibited from paying an indemnity if: (a) the party did not act honestly and in good faith with a view to the best interests of the Company; (b) the proceeding was not a civil proceeding and the party did not have reasonable grounds for believing that his or her conduct was lawful; and (c) the proceeding is brought against the party by the Company or an associated corporation. Directors  Number and Qualification ALDA


The Company

sArticles do not specify a maximum number of directors.  The minimum under British Columbia law for a public company is three.  The number of directors shall be the number of directors fixed by the directors annually or the number that are actually elected at a general shareholders meeting under the Existing Articles. The number of directors is determined, annually, by shareholders at the annual shareholders meeting and all directors are elected at that time. Under the Articles the directors are entitled between successive annual general meetings to appoint one or more additional directors but not more than one-third of the number of directors fixed at a shareholders or actually elected at the preceding annual shareholders meeting.  Directors automatically retire at the commencement of each annual meeting but may be re-elected thereat. Directors must be of the age of majority (18), and meet eligibility criteria including being mentally competent, not an un-discharged bankrupt, no fraud related convictions in the previous five years. There are residency requirements and there is no mandatory retirement age either under the Articles or under the BCA.  Directors need not own any shares of ALDAthe Company in order to qualify as directors. Directors - Powers and Limitations Directors must manage or supervise the management of the business and affairs of the Company and have the authority to exercise all such powers which are not required to be exercised by the shareholders as governed by the BCA.  Directors may, by resolution, create and appoint an executive committee consisting of the director or directors that they deem appropriate.  This executive committee has, during the intervals between meetings of the Board, all of the directors powers, except the power to fill vacancies in the Board, the power to remove a Director, the power to change the membership of, or fill vacancies in, any committee of the Board and any such other powers as may be set out in the resolution or any subsequent directors resolution.  Directors may also by resolution appoint one or more committees other than the executive committee.  These committees may be delegated any of the directors powers except the power to fill vacancies on the board of directors, the power to remove a director, the power to change the membership or fill vacancies on any committee of the directors, and the power to appoint or remove officers appointed by the directors.  Alda Pharmaceuticals Corp. 2007 20F/A Page 49 
---------------------------------------------------------------------------------------------------------------------------------------------------------    Under the BCA, directors are obligated to abstain from voting on matters in which they may be financially interested after disclosing in writing such interest.  Directors compensation is not a matter on which they must abstain.  Directors borrowing powers are not generally restricted where the borrowing is in ALDAthe Companys best interests, but the directors may not authorize ALDAthe Companyto provide financial assistance for any reason where ALDAthe Company is insolvent or the providing of the guarantee would render it insolvent. Amendment of Articles and Notice of Articles; Special Transactions The Articles provide that the general authority required to amend all provisions of the Companys Articles and the Notice of Articles relating to the authorized share structure is a resolution of the directors and the attachment of special rights and restrictions thereto, including any changes therein, an ordinary resolution.  If the amendment prejudices or interferes with the rights or special rights attached to any class of issued shares, by the provisions of the BCA, the consent of the holders of that class of shares by a special separate resolution is also required. Certain corporate changes or proposed transactions including amalgamation with another company, sale of substantially all of ALDAthe Companys assets, re-domiciling out of the jurisdiction of British Columbia, creation of new classes of shares not only require the consent of the holders of common shares by a special separate resolution but generally also give rise to a dissent right which is the right to be paid the fair value of the stockholders shares in cash if the required special resolution is actually passed and ALDAthe Company elects to proceed with the matter notwithstanding receipt of dissent notices.  A notice of a shareholders meeting at which such a change or proposed transaction is intended to be considered must include a prominent notice of the dissent right.  Dissent provisions are governed by the BCA and not by the Articles of ALDAthe Company. Under the Articles, a special separate resolution requires a majority of three-quarters of the votes cast. Shareholders Meetings In addition to reflecting the present notice and other provisions of the BCA relating to shareholders meetings, the Articles provide that shareholders meetings may be held at such place as is determined by the directors.  Shareholders meetings are governed by the Articles of ALDAthe Company but many important protections and procedures are contained within the BCA and the Securities Act (British Columbia) and the Securities Act (Alberta) and the respective regulations and rules thereto and the policy statements, notices and blanket orders of the respective commissions of each of British Columbia and Alberta, together with the national policy statements, and national instruments applied by the such commissions (collectively, Applicable Canadian Securities Law).  The Articles provide that ALDAthe Company will hold an annual shareholders meeting, will provide at least 21 days notice and will provide for certain procedural matters and rules of order with respect to conduct of the meeting.  The BCA and Applicable Canadian Securities Law superimpose requirements that generally provide that shareholders meetings require not less than a 60 day notice period from initial public notice and that ALDAthe Companymakes a thorough advanced search of intermediary and brokerage registered shareholdings to facilitate communication with beneficial shareholders so that meeting proxy and information materials can be sent via the brokerages to unregistered but beneficial shareholders.  The form and content of information circulars and proxies and like matters are governed by Applicable Canadian Securities Law and includes the specifies relating to disclosure requirements for the proxy materials and various corporate actions, background information on the nominees for election for director, executive compensation paid in the previous year and full details of any unusual matters or related party transactions.  ALDAThe Companymust hold an annual shareholders meeting open to all shareholders for personal attendance or by proxy at each shareholders determination.  The meeting must be held within 13 months of the previous annual shareholders meeting and must present audited statements which are dated no more than six months prior to such meeting. Change in Control ALDA


The Companyhas not implemented any shareholders rights or other poison pill protection against possible take-overs.ALDA


the Companydoes not have any agreements which are triggered by a take-over or other change of control.  There are no provisions in its articles triggered by or affected by a change in outstanding shares which gives rise to a change in control.  There are no provisions inALDA


the Company

s material agreements giving special rights to any person on a change in control.  Alda Pharmaceuticals Corp. 2007 20F/A Page 50 
---------------------------------------------------------------------------------------------------------------------------------------------------------    Insider Share Ownership Reporting The Articles of

ALDA


the Company

 do not require disclosure of share ownership.  Share ownership of director nominees must be reported annually in proxy materials sent to ALDAthe Companys shareholders.  There are no requirements under the BCA to report ownership of shares of ALDAthe Company but Applicable Canadian Securities Law requires disclosure of trading by insiders (generally officers, directors and holders of 10% of voting shares) within 10 days of the trade.  Controlling shareholders (generally those in excess of 20% of outstanding shares) must provide seven days advance notice of share sales. Applicable Canadian Securities Law Applicable Canadian Securities Law governs matters typically pertaining to public companies such as continuous quarterly financial reporting, immediate disclosure of material changes, insider trade reporting, take-over protections to ensure fair and equal treatment of all shareholders, exemption and resale rules pertaining to non-prospectus securities issuances as well as civil liability for certain misrepresentations, disciplinary, appeal and discretionary ruling matters.  All ALDAof the Companys shareholders regardless of residence have equal rights under this legislation



except as provided for in the Voting Agreement (Exhibit 3.a.). 10.C.  Material Contracts    Linns (Exhibit 4.f.)

The Company is no longer pursuing any registrations either directly or through agents, except in China through He-Yi , as noted below and in Exhibit 4.g. Esthetics Plus (Exhibit 4.h.)

The Company appointed EP as its exclusive distributor to the beauty industry throughout all the provinces and territories within Canada except for the province of British Columbia, in which the distributorship is non-exclusive (the Territory). The initial term is three years. Thereafter, the Agreement is automatically renewed on each anniversary date for another year unless either party provides the other with written notice, not later than one hundred twenty (120) days prior to the expiration of the term still in effect, of its desire to end the Agreement upon the expiration of the term.

Fuzhou:

In May 25, 2007, the Agreement with Fuzhou Xinmei Biotech Co. Ltd. (Fuzhou), which allowed manufacturing and marketing in Fujian province in China, was transferred to He-Yi She Ye Limited (He-Yi) and expanded to cover marketing in all of China. On August 31, 2006, He-Yi received its certificate of  approval from the Fujian Centre of  Disease Control for T36® Disinfectant after passing all of the required tests. This certificate allowed He-Yi to apply to the Chinese National Centre for Health Inspection and Supervision for approval to manufacture T36® Disinfectant for sale in China and for export. The registration of T36® Disinfectant in China was expanded beyond disinfection of inanimate objects, such as hospital equipment and instruments, to also allow external use on humans, including use as a first-aid antiseptic and hand sanitizer. Approval for the manufacturing of T36® Disinfectant was obtained from  the Ministry of Health in The Peoples Republic of China. On April 19, 2007, a manufacturing certificate (Certificate of Approval (Health ID. No. 0109) was granted to He-Yi for a period of four years from April 19, 2007 to April 18, 2011 and is renewable by filing an application for renewal 6 months before the expiry date. The agreement with He-Yi provides that, ALDA will provide He-Yi with all information that ALDA has at its disposal to assist with the registration of ALDAs products in China, He-Yi will be responsible for procuring all necessary government approvals for ALDAs products within 6 months from the time all technical data to support the application is provided by ALDA, quarterly reports on the progress of the approvals will be provided to ALDA by He-Yi, an extension may be requested by He-Yi to procure all necessary government approvals and may not be unreasonably refused by ALDA for recurring periods of 3 months if: He-Yi is employing its best efforts in obtaining the registration of the ALDA products in China and is providing quarterly reports as required or more time is required by ALDA Pharmaceuticals Corp. to obtain information required by He-Yi. ALDA Pharmaceuticals Corp. will provide He-Yi with the specifications required for He-Yi to provide a manufacturing facility suitable for the manufacturing of ALDAs products. He-Yi will provide a fully equipped manufacturing facility according to the specifications provided by ALDA, to produce the ALDA products subject to He-Yi employing its best efforts to obtain the space, materials and equipment specified by ALDA and He-Yi will have the right to distribute ALDAs products in China subject to ALDAs approval of each distributorship. The Agreement is effective until April 18, 2011 (the Initial Term).  Upon expiration of the Initial Term, the Agreement may be renewed for additional periods, (the Renewals) provided that ALDA and He-Yi have each met all of their obligations under the Agreement and provided that He-Yi is able to obtain renewals of the Certificate of Approval (Health ID. No. 0109) that has been granted by the Ministry of Health of the Peoples Republic of China and expires on April 18, 2011. Any Renewals will reflect current market conditions in the territory served by He-Yi at the time the Renewals are granted and the time periods of any Renewals will be the same as the corresponding time periods of the renewals of the Certificate. For the first 3 years after production is started by He-Yi and within 6 months after production is started by He-Yi, ALDA and He-Yi will establish minimum sales levels and, thereafter, after each new distributorship is established. He-Yi will pay ALDA a royalty, based on the gross revenues received by He-Yi for all of ALDAs products sold in China as follows: · 5% during the first and second year after production is started by He-Yi, · 8% during the third year, · 6% after a doubling of sales over the sales achieved in the second year has occurred. · He-Yi will pay ALDA a 10% royalty based on the gross revenues received by He-Yi for all of ALDAs products sold by He-Yi outside of China. · All royalties will be paid monthly within 30 days after each month end.

Alda Pharmaceuticals Corp. 2007 20F/A Page 52 
---------------------------------------------------------------------------------------------------------------------------------------------------------    He-Yi (Exhibit 4.g.) On May 25, 2007, the Agreement with Fuzhou Xinmei Biotech Co. Ltd. (Fuzhou), which allowed manufacturing and marketing in Fujian province in China (Exhibit 4.c.), was transferred to He-Yi She Ye Limited (He-Yi) and expanded to cover marketing in all of China (Exhibit 4.g.).  The agreement with He-Yi provides that: · the Company will: · provide He-Yi with all information that ALDA has at its disposal to assist with the registration of the Companys products in China, · provide He-Yi with the specifications required for He-Yi to provide a manufacturing facility. · He-Yi will: · procure all necessary government approvals for the Companys products, · provide quarterly reports on the progress of the approvals to the Company with extensions to be granted by the Company if He-Yi is employing its best efforts to achieve registrations · provide a manufacturing facility according to the specifications provided by the Company · distribute the Companys products in China, subject to the Companys approval of each distributorship and · sell its products to the Company as requested by the Company and · ship products to customers of the Company located in other countries.

Linns:

The Company has a 5 year licensing and distribution agreement with Linns Corporation Sdn Bhd (Linns) (see Exhibit 4.F.) with an effective date of August 1, 2004.  The Territory is defined as Brunei, Cambodia, Indonesia, Japan, Laos, Malaysia, Myanmar, Philippines, Singapore, South Korea, Taiwan, Thailand, Vietnam, subject to Linns submitting the required applications required for regulatory approval of T36®Disinfectant in each part of the Territory. Registration of T36®Disinfectant in Malaysia is being left to the discretion of the Linns because the Company is not knowledgeable about the registration requirements of jurisdictions outside of North America. On the Companys behalf, Linns submitted its T36®Disinfectant to the National Pharmaceutical Control Bureau, Ministry of Health, Malaysia and received approval in January of 2005 to sell T36®Disinfectant as a disinfectant, disinfectant cleaner sanitizer and deodorizer in Malaysia. However, because the T36 Disinfectant could be flammable, the Company needs approval from Malaysias Department of Fire & Rescue before T36®Disinfectant can be stored at Linns warehouse.  This approval has not yet been obtained. Linns is obliged to meet minimum sales levels that are mutually agreed upon by Linns and the Company and to purchase T36®Disinfectant from the Company. Linns has a Right of First Refusal to manufacture T36®Disinfectant for the Territory. If Linns meets the minimum sales obligations, the agreement is renewable for an additional 5 years. The termination provisions of the agreement are standard commercial terms that include uncorrected breaches of the agreement and any form of insolvency on the part of Linns or the Company. 10.D.  Exchange Controls Canada has no system of exchange controls.  There are no Canadian restrictions on the repatriation of capital or earnings of a Canadian public company to non-resident investors.  There are no laws in Canada or exchange restrictions affecting the remittance of dividends, profits, interest, royalties and other payments to non-resident holders of the Companys securities, except as discussed in ITEM 10, Taxation" below. Restrictions on Share Ownership by Non-Canadians:  There are no limitations under the laws of Canada or in the organizing documents of the Company on the right of foreigners to hold or vote securities of the Company, except that the Investment Canada Act may require review and approval by the Minister of Industry (Canada) of certain acquisitions of "control" of the Company by a "non-Canadian". The threshold for acquisitions of control is generally defined as being one-third or more of the voting shares of the Company. "Non-Canadian" generally means an individual who is not a Canadian citizen, or a corporation, partnership, trust or joint venture that is ultimately controlled by non-Canadians.  If a non-Canadian (for example, a US resident acquirer) were to acquire such a control position, they would not be required to do any filings or provide any notices to the Ministry of Industry (Canada) unless notified first by that Ministry that their acquisition of control was under review. Canada has, as does the United States, competition laws designed to promote competition in industry and markets.  The Competition Act (Canada) provides Canadas federal government with the power to review or prevent business transactions, such as acquiring a controlling interest in a company similar to the Company , if it is found that the acquisition of control would reduce competition in a given market or industry.  Since the market that the Company competes in is extremely competitive, no single company, including the Company, seems to have significant market power. Acquisition of the Company, therefore, would not lead to reduced competition.  Alda Pharmaceuticals Corp. 2007 20F/A Page 53 
---------------------------------------------------------------------------------------------------------------------------------------------------------    10.E.  Taxation  Canadian Federal Income Tax Considerations: The following is a brief summary of some of the principal Canadian federal income tax consequences to a holder of common shares of the Company (a "U.S. Holder") who deals at arm's length with the Company, holds the shares as capital property and who, for the purposes of the Income Tax Act (Canada) (the "Act") and the Canada  United States Income Tax Convention (the "Treaty"), is at all relevant times resident in the United States, is not and is not deemed to be resident in Canada and does not use or hold and is not deemed to use or hold the shares in carrying on a business in Canada.  Special rules, which are not discussed below, may apply to a U.S. Holder that is an insurer that carries on business in Canada and elsewhere. Under the Act and the Treaty, a U.S. Holder of common shares will generally be subject to a 5% withholding tax on dividends paid or credited or deemed by the Act to have been paid or credited on such shares.  The withholding tax rate is 5% where the U.S. Holder is a corporation that beneficially owns at least 10% of the voting shares of the Company and the dividends may be exempt from such withholding in the case of some U.S. Holders such as qualifying pension funds and charities. In general, a U.S. Holder will not be subject to Canadian income tax on capital gains arising on the disposition of shares of the Company unless (i) at any time in the five-year period immediately preceding the disposition, 25% or more of the shares of any class or series of the capital stock of the Company was owned by (or was under option of or subject to an interest of) the U.S. holder or persons with whom the U.S. holder did not deal at arm's length, and (ii) the value of the common shares of the Company at the time of the disposition derives principally from real property (as defined in the Treaty) situated in Canada. For this purpose, the Treaty defines real property situated in Canada to include rights to explore for or exploit mineral deposits and other natural resources situated in Canada, rights to amounts computed by reference to the amount or value of production from such resources, certain other rights in respect of natural resources situated in Canada and shares of a corporation the value of whose shares is derived principally from real property situated in Canada. The US Internal Revenue Code provides special anti-deferral rules regarding certain distributions received by US persons with respect to, and sales and other dispositions (including pledges) of stock of, a passive foreign investment company. A foreign corporation, such as the Company, will be treated as a passive foreign investment company if 75% or more of its gross income is passive income for a taxable year or if the average percentage of its assets (by value) that produce, or are held for the production of, passive income is at least 50% for a taxable year. The Company believes that it was not a passive foreign investment company for the taxable year ended December 31, 2007 and, furthermore, expects to conduct its affairs in such a manner so that it will not meet the criteria to be considered passive foreign investment company in the foreseeable future. Dividends: A Holder will be subject to Canadian withholding tax ("Part XIII Tax") equal to 25%, or such lower rate as may be available under an applicable tax treaty, of the gross amount of any dividend paid or deemed to be paid on common shares.  Under the Canada-U.S. Income Tax Convention (1980) as amended by the Protocols signed on 6/14/1983, 3/28/1984, 3/17/1995, and 7/29/1997 (the "Treaty"), the rate of Part XIII Tax applicable to a dividend on common shares paid to a Holder who is a resident of the United States and who is the beneficial owner of the dividend, is 5%.  If the Holder is a company that owns at least 10% of the voting stock of the Company paying the dividend, and, in all other cases, the tax rate is 15% of the gross amount of the dividend.  The Company will be required to withhold the applicable amount of Part XIII Tax from each dividend so paid and remit the withheld amount directly to the Receiver General for Canada for the account of the Holder. Disposition of Common Shares: A Holder who disposes of a common share, including by deemed disposition on death, will not normally be subject to Canadian tax on any capital gain (or capital loss) thereby realized unless the common share constituted "taxable Canadian property" as defined by the Tax Act.  Generally, a common share of a public corporation will not constitute taxable Canadian property of a Holder if the share is listed on a prescribed stock exchange unless the Holder or persons with whom the Holder did not deal at arm's length alone or together held or held options to acquire, at any time within the five years preceding the disposition, 25% or more of the shares of any class of the capital stock of the Company.  The Canadian Venture Exchange is a prescribed stock exchange under the Tax Act.  A Holder who is a resident of the United States and realizes a capital gain on a disposition of a common share that was taxable Canadian property will nevertheless, by virtue of the Treaty, generally be exempt from Canadian tax thereon unless:  Alda Pharmaceuticals Corp. 2007 20F/A Page 54 
---------------------------------------------------------------------------------------------------------------------------------------------------------     (a) More than 50% of the value of the common shares is derived from, or from an interest in, Canadian real  estate, including Canadian mineral resource properties, (b) The common share formed part of the business property of a permanent establishment that the Holder has or had in Canada within the 12 month period preceding the disposition, or (c) The Holder is an individual who (i) was a resident of Canada at any time during the 10 years immediately preceding the disposition, and for a total of 120 months during any period of 20 consecutive years, preceding the disposition, and (ii) owned the common share when he ceased to be resident in Canada. A Holder who is subject to Canadian tax in respect of a capital gain realized on a disposition of a common share must include three quarters of the capital gain (taxable capital gain) in computing the Holder's taxable income earned in Canada.  The Holder may, subject to certain limitations, deduct three-quarters of any capital loss (allowable capital loss) arising on a disposition of taxable Canadian property from taxable capital gains realized in the year of disposition in respect to taxable Canadian property and, to the extent not so deductible, from such taxable capital gains realized in any of the three preceding years or any subsequent year. United States Taxation: For federal income tax purposes, an individual who is a citizen or resident of the United States or a domestic corporation ("U.S. Taxpayer") will recognize a gain or loss on the sale of the Company's common shares equal to the difference between the proceeds from such sale and the adjusted tax basis of the common shares.  The gain or loss will be a capital gain or capital loss if the Company's common shares are a capital asset in U.S. Taxpayer's hands. For federal income tax purposes, a U.S. Taxpayer will be required to include in gross income dividends received on the Company's common shares.  A U.S. Taxpayer who pays Canadian tax on a dividend on common shares will be entitled, subject to certain limitations, to a credit (or alternatively, a deduction) against federal income tax liability.  A domestic corporation that owns at least 10% of the voting shares should consult its tax advisor as to applicability of the deemed paid foreign tax credit with respect to dividends paid on the Company's common shares. Under a number of circumstances, United States Investor acquiring shares of the Company may be required to file an information return with the Internal Revenue Service Center where they are required to file their tax returns with a duplicate copy to the Internal Revenue Service Center, Philadelphia, PA 19255.  In particular, any United States Investor who becomes the owner, directly or indirectly, of 10% or more of the shares of the Company will be required to file such a return.  Other filing requirements may apply, and United States Investors should consult their own tax advisors concerning these requirements. The US Internal Revenue Code provides special anti-deferral rules regarding certain distributions received by US persons with respect to, and sales and other dispositions (including pledges) of stock of, a passive foreign investment company.  A foreign corporation, such as the Company, will be treated as a passive foreign investment company if 75% or more of its gross income is passive income for a taxable year or if the average percentage of its assets (by value) that produce, or are held for the production of, passive income is at least 50% for a taxable year.  The Company believes that it was not a passive foreign investment company for the taxable year ended December 31, 2007 and, furthermore, expects to conduct its affairs in such a manner so that it will not meet the criteria to be considered passive foreign investment company in the foreseeable future.  10.F.  Dividends and Paying Agents The Company has not declared any dividends on its common shares for the last five years and does not anticipate that it will do so in the foreseeable future.  The present policy of the Company is to retain future earnings for use in its operations and the expansion of its business. Notwithstanding the aforementioned: the Company is unaware of any dividend restrictions; has no specific procedure for the setting of the date of dividend entitlement; but might expect to set a record date for stock ownership to determine entitlement; has no specific procedures for non-resident holders to claim dividends, but might expect to mail their dividends in the same manner as resident holders.  The Company has not nominated any financial institutions to be the potential paying agents for dividends in the United States.   Alda Pharmaceuticals Corp. 2007 20F/A Page 55

CONTROLS AND PROCEDURES The Company carried out an evaluation, under the supervision and with the participation of the Companys management, including the Companys President, of the effectiveness of the design and operation of the Companys disclosure controls and procedures (as defined in the Exchange Act Rule 13a-15(e)) as of the end of the period covered by this report.  Based upon that evaluation, the President concluded that the Companys disclosure controls and procedures are effective in timely alerting them to material information relating to the Company required to be included in the Companys periodic SEC filings, and that information is recorded, processed, summarized and reported as and when required. There was no significant change in the Companys internal control over financial reporting that occurred during the Companys most recently completed fiscal year ended June 30, 2007 that has materially affected, or is reasonably likely to materially affect, the Companys internal control over financial reporting.  Nor were there any significant deficiencies or material weaknesses in the Company's internal controls requiring corrective actions. ITEM 16.  RESERVED  ITEM 16A. AUDIT COMMITTEE FINANCIAL EXPERT

CODE OF ETHICS The company has not adopted a formal code of ethics because, as a TSX Venture Exchange issuer, the Company is only required have an audit committee. The audit committee is composed of a majority of independent members as discussed above under the heading Item 16.B. Audit Committee Financial Experts. In lieu of a code of ethics, the company has adopted the following methodology with respect to corporate governance. The management of ALDA is responsible for establishing and maintaining disclosure controls and procedures for information relating to the Company, including its consolidated subsidiaries. The Companys management is also responsible for establishing and maintaining adequate internal control over financial reporting. ALDAs Board of Directors facilitates its exercise of independent supervision over management by ensuring that the Board is composed of a majority of independent directors.  The Board, at present, is composed of six directors, all of which are considered to be independent except for Mr. Owen and Mr. Chen who are also senior officers.  In determining whether a director is independent, the Board considers, for example, whether the director has a relationship, which could, or could be perceived to, interfere with the director's ability to objectively assess the performance of management. The Board monitors the ethical conduct of ALDA and its management and ensures that it complies with applicable legal and regulatory requirements, such as those of relevant securities commissions and stock exchanges.  The Board has found that the fiduciary duties placed on individual directors by the Companys governing corporate legislation and the common law, as well as the restrictions placed by applicable corporate legislation on the individual directors participation in decisions of the Board in which the director has an interest, have been sufficient to ensure that the Board operates independently of management and in the best interests of the Company. The Board is specifically responsible for approving long-term strategic plans and annual operating plans and budgets recommended by management.  Board consideration and approval is also required for all material contracts, business transactions and all debt and equity financing proposals.  The independent directors on the Board are also responsible for approving senior executive compensation and retirement plans. The Board delegates to management, through the offices of President and Chief Executive Officer and Chief Financial Officer, responsibility for meeting defined corporate objectives, implementing approved strategic and operating plans, carrying on the Companys business in the ordinary course, managing the Companys cash flow, evaluating new business opportunities, recruiting staff and complying with applicable regulatory requirements.  The Board also looks to management to furnish recommendations respecting corporate objectives, long-term strategic plans and annual operating plans. Given the relatively static composition of the Board of Directors and the Companys management over the last several years, the Board has not appointed a corporate governance committee and these functions are currently performed by the Board as a whole.

A Partnership of Incorporated Professionals  AUDITORS' REPORT  To the Shareholders of Alda Pharmaceuticals Corp.:  We have audited the consolidated balance sheets of Alda Pharmaceuticals Corp. as at June 30, 2007 and the consolidated statements of operations and deficit, and cash flows for the year then ended.  These consolidated financial statements are the responsibility of the company's management.  Our responsibility is to express an opinion on these consolidated financial statements based on our audit.  We conducted our audit in accordance with Canadian generally accepted auditing standards and with the standards of the Public Company Accounting Oversight Board (''PCAOB'') (United States).  Those standards require that we plan and perform an audit to obtain reasonable assurance whether the consolidated financial statements are free of material misstatement.  An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements.  An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.  In our opinion, these consolidated financial statements present fairly, in all material respects, the financial position of the company as at June 30, 2007 and the results of its operations and its cash flows for the years then ended in accordance with Canadian generally accepted accounting principles.  The consolidated balance sheet as at June 30, 2006, the consolidated statement of operations and deficit, and cash flows for the years ended June 30, 2006 and 2005 were audited by predecessor auditors who expressed an opinion without reservation on these statements in their report dated September 15, 2006.  Comments by Auditors for U.S. Readers on Canada - United States Reporting Differences  United States reporting standards of the Public Company Accounting Oversight Board (United States) for auditors require the addition of an explanatory paragraph (following the opinion paragraph) when the financial statements are affect by conditions and events that cast substantial doubt on the Company's ability to continue as a going concern, such as those described in Note 1 to the financial statements.  Our report to the shareholders dated October 17, 2007 is expressed in accordance with Canadian reporting standards which do not permit reference to such conditions and events in the auditors' report when these are adequately disclosed in the financial statements.

---------------------------------------------------------------------------------------------------------------------------------------------------------    ALDAPHARMACEUTICALS CORP. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS FOR THE YEARS ENDED JUNE 30, 2007AND 2006   1. BASIS OF PRESENTATION  These consolidated financial statements include the accounts of ALDA Pharmaceuticals Corp. (the Company) and its wholly-owned subsidiary, Sirona Therapeutics Corp. (Sirona).  The name of the subsidiary was changed on January 10, 2006 from ALDA Institute For Preventative Health Care Inc.  Sirona is an inactive company, the shares of which were acquired pursuant to an asset purchase agreement.  These financial statements have been prepared on a going concern basis, which assumes the realization of assets and settlement of liabilities in the normal course of the business. The Company has yet to achieve a level of revenues adequate to achieve profitability. The application of the going concern assumption is dependent on the ability of the Company to secure sufficient financing, and to develop profitable operations.  Management of the Company believes that it will succeed in meeting those objectives, allowing the continued operation of the company.  20072006Deficit$    2,603,791$    2,041,701Working capital627,73033,169   2. DESCRIPTION OF OPERATIONS  The Company was incorporated under the Company Act of British Columbia on May 30, 2000 and was classified as a Capital Pool Company as defined by the policies of the TSX Venture Exchange (the Exchange).  The Company completed its required Qualifying Transaction on November 13, 2003.   As a result of the Company completing the Qualifying Transaction, it ceased to be a Capital Pool Company, and its shares resumed trading on the Exchange effective November 19, 2003.  The Companys main business activity is the development, production and marketing of infection control agent products, principally a product marketed as T36® Disinfectant.  Effective November 26, 2003, the name of the Company was changed from Duft Biotech Capital Ltd. to ALDA Pharmaceuticals Corp.   3. SIGNIFICANT ACCOUNTING POLICIES  a) Cash and equivalents  Cash and equivalents include cash and highly liquid market instruments with original terms to maturity of less than ninety days at the time of acquisition.  b) Accounts receivable  Accounts receivable is presented net of allowance for doubtful accounts.  The allowance for doubtful accounts reflects estimates of probable losses in accounts receivable.  The allowance is determined based on balances outstanding for over 90 days from the invoice date, historical experience and other current information.  The Company extends credit to customers and distributors; credit checks are required for all new distributors.  Alda Pharmaceuticals Corp. 2007 20F/A Page 67

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS FOR THE YEARS ENDED JUNE 30, 2007AND 2006  3. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  c) Inventory  Inventory of the Companys finished goods and related raw materials is reported at the lesser of cost and estimated net realizable value, and is determined using the first in, first out cost flow assumption.  d) Furniture and equipment  Furniture and equipment are recorded at cost and are amortized using the following annual rates:  Furniture and fixtures 20% Straight line Computer equipment 30% Straight line  e) Impairment of long-lived assets  The Company reviews for the impairment of long-lived assets, including furniture and equipment, whenever changes in circumstances indicate that the carrying amount of an asset may not be recoverable from expected future cash flows.  The assessment of recoverability is made based on projected undiscounted future net cash flows that are directly associated with the assets use and eventual disposition.  The amount of the impairment, if any, is measured as the difference between the carrying value and the fair value of the impaired assets and is presented as an impairment loss in the current period.  f) Patent Application and Development Costs  Patent application and development costs include all expenditures attributable to efforts by the Company to develop, and bring to commercial production a new product as well as to acquire legal protections for its proprietary products, such as trademarks and patents.  Such amounts are charged as an expense in the period incurred except in circumstances where the market and technical feasibility of the product have been established, recovery of these costs can reasonably be regarded as assured, and future values can be realized, in which case such costs are capitalized.  In the latter case, patent application and development costs are amortized on a systematic basis over the patent life of 20 years.  g) Intangible assets  The carrying value of intangible assets which are determined to have a finite useful life are amortized on a systematic basis over the useful life of 20 years.  Intangible assets are subject to an impairment test on an annual basis, based on a comparison of the fair value of the intangible asset to its carrying value.  The carrying value is adjusted for impairment as necessary and any excess of the carrying amount over the fair value of the intangible asset is charged to earnings in the period occurred.  h) Revenue recognition  The revenue of the Company is primarily derived from the sale of the Companys T36® product.  Revenue is recognized at the time of shipment, and invoicing, provided that collection of the amount billed to the customer is reasonably assured.  Revenue is recognized net of any expected sales return.  Credit will be granted to customer for damaged goods.  Alda Pharmaceuticals Corp. 2007 20F/A Page 68 
---------------------------------------------------------------------------------------------------------------------------------------------------------    ALDAPHARMACEUTICALS CORP. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS FOR THE YEARS ENDED JUNE 30, 2007AND 2006  3. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)  i) Income taxes  Income taxes are recorded using the asset and liability method whereby future tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.  Future tax assets and liabilities are measured using enacted or substantively enacted tax rates expected to apply when the asset is realized or the liability settled.  The effect on future tax assets and liabilities of a change in tax rates is recognized in income in the year that substantive enactment or enactment occurs.  To the extent that the Company does not consider it more likely than not that a future tax asset or portion thereof will be recovered, it produces a valuation allowance  j) Stock-based compensation  The fair value of stock options granted is determined using the Black-Scholes option pricing model and recorded as stock-based compensation expense over the vesting period of the stock options.  k) Warrants  Proceeds from issuances by the Company of units consisting of shares and warrants are allocated based on the fair value method, whereby the fair value of warrants is determined using the Black-Scholes option pricing model and recorded as contributed surplus.  The difference between the fair value of the warrants and proceeds received is allocated to share capital.  l) Basis and diluted loss per share  Loss per share is calculated based on the weighted average number of common shares outstanding during the reported period.  Basic loss per share is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding in the year.  The Company uses the treasury stock method to compute the dilutive effect of options, warrants and similar instruments.  Under this method, the dilutive effect on loss per share is recognized on the use of the proceeds that could be obtained upon exercise of options, warrants and similar instruments.  It assumes that the proceeds would be used to purchase common shares at the average market price during the year.  For the years  m) Measurement Uncertainty  The preparation of these consolidated financial statements in accordance with Canadian generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and the reported amount of revenues and expenses during the period.  Areas requiring significant management estimates include valuation of intangible assets, estimated useful life of intangible assets, estimate useful life of patent application and development costs, stock based compensation expense, and valuation of share purchase warrants.  Actual results could differ from these estimates.  n) Financial instruments  The Companys financial instruments consist of cash and equivalents, accounts receivable, subscriptions receivable, accounts payable and accrued liabilities.  The fair value of these instruments approximates the carrying amounts due to the immediate or short-term maturity of these financial instruments.  It is managements option that the Company is not exposed to significant interest, currency, or credit risk arising from these financial instruments.   Alda Pharmaceuticals Corp. 2007 20F/A Page 69

INTANGIBLE ASSETS  The intangible assets balance represents the carrying amount of certain intellectual property acquired in its Qualifying Transactions.  The opening balance of Intangibles as at July 1, 2006 was determined as follows:  Original Purchase Cost$  540,000Less:Impairment Loss in 2004$   (179,000)Impairment Loss in 2005(245,000)Impairment Loss in 2006-(424,000)Balance as at June 30, 2006$  116,000  At June 30, 2005, the carrying cost of the intangible assets was written down to the estimated net recoverable amount, and an impairment loss of $245,000 was charged against earnings for the 2005 year.  Effective July 1, 2006, the Company changed its estimate of the useful life of the intangible assets from an infinite life to a finite life of 20 years.  The impact of this change in estimate was to increase amortization by $5,800 for the year ended June 30, 2007.

GAIN ON LEGAL SETTLEMENT  (i) A company opposing a trademark application made in Canada by ALDA commenced legal proceedings during the 2003 year claiming damages in respect to alleged infringement of trademark.  ALDA had filed a Statement of Defence.  The Statement of Claim was subsequently amended to add the Company as a defendant in the action.  On May 23, 2005, the Company entered into a Settlement agreement with that company, whereby the Company agreed to terminate the use, and application for registration of, the trademark Viralex. The Company must discontinue the use of that trademark in advertising and other promotional disclosures, liquidate its inventory of goods bearing the trademark Viralex, and rename the Viralex product within twelve months from the date of the agreement, in consideration for payment of $30,000 (US). These funds were held in escrow by the Companys lawyer until the Company issued a press release regarding the settlement of the trademark dispute, and withdrew its application for the Viralex trademark, which occurred during the period ended September 30, 2005.  (ii) On August 2, 2005, the Company received the proceeds from the Companys lawyer regarding the settlement of the trademark dispute. The proceeds of the settlement for a total amount of $37,383 ($30,000 (US)) have been recorded in the Statement of Operations and Deficit as Gain on legal settlement for the period ended September 30, 2005.  During the 2005 year, the Company commenced legal action against the competitor described above with respect to certain alleged defamatory statements made by the competitor.  This claim was settled effective July 12, 2006, by an agreement under which the Company is to receive an amount of $15,000 from the competitor.  The proceeds of the settlement, net of associated legal costs in the amount of $4,455, have been recognized in the Statement of Operations and Deficit for the period ended June 30, 2007.  9. MAJOR CUSTOMERS  For the year ended June 30, 2007, revenue from each of four customers exceeded 10% of total revenue (2006: four customers; 2005: five customers).

UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES  These financial statements have been prepared in accordance with Canadian generally accepted accounting principles in Canada (Canadian GAAP) which are substantially the same as principles applicable in the United States (US GAAP) and practices prescribed by the United States Securities and Exchange Commission (SEC), except for the following:  a) Comprehensive income:  Statement of Financial Accounting Standards No. 130 requires the reporting of Comprehensive Income.  Comprehensive income includes net income plus other comprehensive income.  Other comprehensive income includes all changes in equity of a company during the period arising from non-owner sources.  The Company did not have any other comprehensive income during the years ended June 30, 2007 and 2006.  b) Product development costs:  Under Canadian GAAP, product development costs are charged as an expense in the period incurred except in circumstances where the market and feasibility of the product have been established, and recovery of development costs can reasonably be regarded as assured, in which case such costs are capitalized.  US GAAP requires that these expenditures be expense in the year incurred.  The Company has not capitalized any product development costs during the years ended June 30, 2007 and 2006.  c) Recent United States Accounting Pronouncements:  Selected recent pronouncements issued by the Financial Accounting Standards Board (FASB) are summarized below.  None of these changes are expected to have a material impact on the financial statements of the Company.  Alda Pharmaceuticals Corp. 2007 20F/A Page 79 
---------------------------------------------------------------------------------------------------------------------------------------------------------    ALDAPHARMACEUTICALS CORP. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS FOR THE YEARS ENDED JUNE 30, 2007 AND 2006   16. UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES (CONTINUED)  c) Recent United States Accounting Pronouncements  (i) In December of 2004, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 123 (revised 2004) (Share-Based Payments) (SFAS 123R).  SFAS 123R is a revision of SFAS 123, and supersedes APB 25.  SFAS 123R requires that the fair value of employees awards of share-based payments which are issued, modified, repurchased or cancelled after the implementation date, is to be measured as of the date the award is issued, modified, repurchased or cancelled and the resulting cost recognized in the statement of earnings over the service period.  SFAS 123R will be effective for the Companys year ended June 30, 2007.  (ii) The Fair Value Option for Financial Assets and Financial Liabilities  In February 2007, the Financial Accounting Standards Board (FASB) issued SFAS No. 159, The Fair Value Option for Financial Assets and Financial Liabilities  Including an Amendment of FASB Statement No. 115.  This statement permits entities to choose to measure many financial instruments and certain other items at fair value.  Most of the provisions of SFAS No. 159 apply only to entities that elect the fair value option.  However, the amendment to SFAS No. 115 Accounting for Certain Investments in Debt and Equity Securities applies to all entities with available-for-sale and trading securities.  SFAS No. 159 is effective as of the beginning of an entitys first fiscal year that begins after November 15, 2007.  Early adoption is permitted as of the beginning of a fiscal year that begins on or before November 15, 2007, provided the entity also elects to apply the provision of SFAS No. 157, Fair Value Measurements.  (iii) Fair Value Measurements  In September 2006, the Financial Accounting Standards Board (FASB) issued SFAS No. 157, Fair Value Measurements.  The objective of SFAS No. 157 is to increase consistency and comparability in fair value measurements and to expand disclosures about fair value measurements.  SFAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements.  SFAS No. 157 applies under other accounting pronouncements that require or permit fair value measurements and does not require any new fair value measurements.  The provisions of SFAS No. 157 are effective for fair value measurements made in fiscal years beginning after November 15, 2007.  (iv) Accounting for Uncertainty in Income taxes  In June 2006, the Financial Accounting Standards Board (FASB) issued Interpretation No. 48 (FIN 48).  FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprises financial statements in accordance with FASB Statement No. 109 Accounting for Income Taxes (SFAS 109).  The interpretation prescribes a recognition threshold and measurement attribute to the financial statement recognition and measurement of tax position taken or expected to be taken in a tax return.  FIN 48 also provides accounting guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.  FIN 48 is effective for fiscal years beginning after December 15, 2006.  We will adopt the provisions of FIN 48 on July 1, 2007.  17.

MANAGEMENT DISCUSSION AND ANALYSIS (MD&A) FOR THE YEAR ENDED JUNE 30, 2007  1.1 Date  This Management Discussion and Analysis (MD&A) is dated October 26, 2007 and should be read in conjunction with the consolidated financial statements of ALDA Pharmaceuticals Corp. (ALDA or the Company) for the financial year ended June 30, 2007. All financial information is expressed in Canadian dollars and is prepared in accordance with Canadian generally accepted accounting principles (GAAP).  1.2 Overall Performance  On November 13, 2003, ALDA Pharmaceuticals Corp., formerly Duft Biotech Capital Ltd., completed the acquisition of the assets of 513947 BC Ltd. formerly ALDA Pharmaceuticals Inc. (the Qualifying Transaction) and a $1.2 Million financing arranged by Canaccord Capital Corporation (the Financing).ALDA trades on the TSX Venture Exchange in Vancouver, Canada under the symbol APH.  ALDA has developed a patent-pending infection control formulation, referred to as T36®, which is incorporated into therapeutic applications such as treatments for topical and vulvovaginitis infections, hand hygiene products, a skin antiseptic for clinical and consumer use and a first-aid ointment. Studies have been performed on the T36® formulation which demonstrates its ability to kill all types of infectious micro-organisms within 3 minutes and tuberculosis within 5 minutes. Toxicology studies on animals have also demonstrated that the T36® formulation is not toxic.  There is competition in all of the therapeutic markets that the company has targeted. However, the T36® formulation is not expensive to manufacture and can be used in a broad variety of infection-control products. Toxicology and efficacy studies have already demonstrated that the T36® formulation is not toxic and is effective at killing all bacteria, viruses and fungi. The intended applications are topical, except for the vulvovaginitis treatment, so that registration is expected be faster and less expensive than for drugs that are taken internally. Rather than disrupting metabolic pathways, the T36® formulation consists of four anti-microbial ingredients in relatively low concentrations that act synergistically to disrupt the physical structure of the infectious agents. This approach prevents microbial resistance from developing. None of the active ingredients are known to have any significant side effects on humans.  ALDA has started studies that will satisfy the registration requirements of Health Canada, the US Food and Drug Administration (FDA) and the European Medicines Agency (EMeA) for the targeted applications. In other parts of the world, FDA or EMeA testing is generally accepted for registration applications. If the company decides to register the products in China, it is likely that the testing will have to be repeated in China unless there is harmonization of the requirements in the meantime.  The overall strategy for the T36® products is to first secure registration as prescription products so that marketing and sales can be focused on pharmaceutical distributors that serve physicians. As efficacy and safety of the products are established, registration as over-the-counter (OTC) products will be sought. Once OTC status is secured, the sales and marketing focus will shift to distributors that serve pharmacies.  To complete this plan, the company will need to raise money in the public markets. This will increase the number of shares outstanding and will lead to further dilution of existing shareholders.  Market knowledge of the ALDA name is limited.  ALDA will need to devote considerable resources to educate new markets about the products the Company offers.  In establishing new markets, the Company will be competing with companies that are potentially already entrenched in such markets or that may be better funded than the Company.  ALDA also faces significant costs and risks associated with the protection and exploitation of its intellectual property, given that the patents have not yet been granted to the Company.  Competitors with significantly more resources may have an advantage over the Company in terms of the establishment, protection and exploitation of patents and other intellectual property.  All of these factors are material to the Company and its business.  Alda Pharmaceuticals Corp. 2007 20F/A Page 82

The improvement of the Companys cash position compared to June 30, 2006 was primarily attributed to funds received from a private placement arranged by the Company prior to June 30, 2007. For the same reasons, current assets increased by $609,325 from $92,673 to $701,998.  Patent application and development costs incurred during the 2007 year were capitalized with a useful life of 20 years.

Legal and accounting fees (continued) As announced in a news release issued by the company on September 13, 2007, Berris Mangan resigned as the Companys auditor due to a decision by Berris Mangan to focus its practice on TSX-listed companies with Canadian reporting responsibilities. The Company confirmed that there are no reportable events (as such term is defined in National Instrument 51-102 of the Canadian Securities Administrators) and appointed HLB Cinnamon Jang Willoughby, Chartered Accountants (CJW) as the interim auditor to conduct the year-end audit.  Product Registration and Development Costs Total costs incurred in this category for the year ended June 30, 2007 was $42,617 and capitalized under patent application and development costs.

---------------------------------------------------------------------------------------------------------------------------------------------------------    ALDA PHARMACEUTICALS CORP. MANAGEMENT DISCUSSION AND ANALYSIS (MD&A) FOR THE YEAR ENDED JUNE 30, 2007  1.4 Results of Operations (continued)  Loss from operations The loss from operations was $562,090 for the year ended June 30, 2007 (2006: $380,026).  Losses for the year ended June 30, 2007 were greater than for previous years due to non-cash stock options granted to certain officers, consultants, directors and an employee during the year.  The amortization expense increased to $16,281, an increase of 97% compared to previous years.  Such increase was mainly due to the amortization of intangible assets and the capitalized patent application costs.   A number of initiatives were taken during the year to promote further growth of the company, including private placements, expanding the patent portfolio of the company, seeking expert advice on product registrations undertaking laboratory tests of T36® Disinfectant, preparing marketing materials, evaluating new manufacturing facilities, and seeking out new distributors and customers.  Comparing to the 2006 fiscal year, sales of T36® Disinfectant for the 2007 fiscal year increased by 14%, while expenses increased by approximately 33%.  Loss from operations (continued) Management continues to work towards the launch of new products, including T36® Personal Disinfectant, T36® Hand Sanitizer and the therapeutic products. The pursuit of the new therapeutics products requires the Company to invest continuously in product development, clinical trials, product registrations and intellectual property protection.  As a result, further losses will be anticipated in the subsequent periods. Management continues to work towards the launch of new products, including T36® Personal Disinfectant, T36® Hand Sanitizer and the therapeutic products. The pursuit of the new therapeutics products requires the Company to invest continuously in product development, clinical trials, product registrations and intellectual property protection.  As a result, further losses will be anticipated in the subsequent periods.  Other income (Loss) Interest income earned from the deposits for the year ended June 30, 2007 was zero (2006: $1,725).  The intangible asset originally estimated at $540,000 was written down to $116,000 in the 2005 fiscal year due to the devaluation of the assets purchased by the Company for its Qualifying Transaction.  Because the management of the Company anticipated that the net recoverable amount of the intangible asset exceeded the carrying value, no further impairment loss was recognized for the 2006 year.  The anticipated net recoverable amount was calculated based on the undiscounted future cash flows.  During 2007 fiscal year, the carrying value of intangible asset was determined to have an estimated finite life of 20 years.  During the 2005 fiscal year, the Company entered into a settlement agreement with a claimant, whereby the Company agreed to terminate the use, and application for registration of, the trademark Viralex. The settlement agreement required the Company to liquidate its inventory of goods bearing the trademark within twelve months from the date of the agreement in all advertising and other promotional means. In connection with the settlement of the trademark depute, a gain of $37,383 ($30,000 US), previously held by the Companys lawyer, was recognized the Company and reported in the Statement of Operations and Deficit as a gain on legal settlement for the 2006 year.  During the 2005 year, the Company commenced legal action against the competitor described above with respect to certain alleged defamatory statements made by the competitor.  This claim was settled effective July 12, 2006, by an agreement under which the Company is to receive an amount of $15,000 from the competitor.  The proceeds of the settlement, net of associated legal costs in the amount of $4,455, have been recognized in the Statement of Operations and Deficit for the period ended June 30, 2007.

---------------------------------------------------------------------------------------------------------------------------------------------------------    ALDA PHARMACEUTICALS CORP. MANAGEMENT DISCUSSION AND ANALYSIS (MD&A) FOR THE YEAR ENDED JUNE 30, 2007   1.4 Results of Operations (continued)  Loss for the year The loss for the year ended June 30, 2007 was $562,090 (2006: $378,301).  The increases in losses for 2007 were mainly due to higher levels of non-cash stock-based compensation to consultants, directors, officer and an employee while losses for 2006 were offset by a gain of a legal settlement in connection with the settlement of the trademark depute.  Use of proceeds  The net proceeds received from the closing of recent private placements will be used for working capital including such activities as starting initial clinical trails of the T36® formulation in therapeutic products, registering T36® products in major markets, seeking expert advice on product regulatory issues, re-branding and advertising current and new lines of products and seeking possible registration of ALDAs securities in foreign jurisdictions.  1.5 Summary of Quarterly Results. Quarter endedJun/07Mar/06Dec/06Sep/06Jun/06Mar/06Dec/05Sep/05Revenue61,43372,87964,35657,57558,72447,69460,28556,883Net loss302,34584,83178,32496,59167,371118,084137,21355,633Loss/share0.000.000.000.000.000.010.010.00Total assets854,166176,316175,743208,281216,8722207,800319,192237,141  The revenues generated from the sale of T36® Disinfectant have been relatively consistent while a reduction in operating expenses has been realized. Resources spent in patenting, research and development, and product registrations have been capitalized with an amortization period of 20 years. The greater loss recognized in 2007 fiscal year was mainly due the non-cash stock options granted to certain officers, directors, consultants and an employee and increased consulting fees and wages.  No further impairment loss was recognized from the intangible assets as the intangible assets were determined to have a definite life of 20 years commencing July 1, 2006.   Prior to July 1, 2006, the intangible assets deemed to have an indefinite life subject to annual test of impairment.  $245,000 impairment loss on intangible assets was incurred for the fiscal year 2005 which reduced the carrying value of the intangible assets to $116,000. No further impairment loss was recognized for the fiscal year 2006.  In connection with the settlement of legal disputes, the Company recognized a net gain of $10,545 and $37,383 in fiscal years 2007 and 2006, respectively.  Total assets were increased over the quarters as a result of receiving external funding from the private placements. All resources will be used in marketing, product development, intellectual property protection and the other requirements of an operating company that is introducing a new technology and products to the market  1.6 Liquidity  Although the company generates revenues from the sale of its lead product, T36®Disinfectant, sales are still occurring only in Canada. Approvals have been obtained for T36®Disinfectant in the European Union and China and the Company will be pursuing opportunities in these markets. The company has also established a plan for the development, testing, registration and marketing of therapeutic applications of the T36® formulation The Company will need to undertake further financings in order pursue these plans and these financings will lead to the dilution of current shareholders of the Company.

---------------------------------------------------------------------------------------------------------------------------------------------------------     ALDA PHARMACEUTICALS CORP. MANAGEMENT DISCUSSION AND ANALYSIS (MD&A) FOR THE YEAR ENDED JUNE 30, 2007  1.7 Capital resources  On September 13, 2006, the Company raised net proceeds of $71,500 by selling a total of 1,430,000 Units of the Companys at price of $0.05 per Unit. Each Unit consisted of one common share of the Company and one warrant that entitled the holder to purchase one additional common share at a price of $0.10 per share for a period of 12 months following the closing date.  The estimated fair value of warrants being $20,020 was allocated to contributed surplus for warrants. On June 7, 2007, the Company completed a private placement of 8,000,000 Units at a price of $0.10 per unit for net proceeds of $793,820.  Each Unit consist of one common share and one warrant that entitles the holder to purchase one additional common share at a exercise price of $0.20 per share until June 7, 2008 and, thereafter at a price of $0.30 per share until June 7, 2009.  The estimated fair value of warrants being $384,000 was allocated to contributed surplus for warrants. The net proceeds will be used for general working capital. As of June 30, 2007, the Company received funds of $196,200 from the exercise of 1,062,000 warrants and 900,000 options at an exercise price of $0.10.  Option values of $18,000 previously recorded in contributed surplus for options were credited to share capital.  Warrant values of $13,806 previously recorded in contributed surplus for warrants were credited to share capital. At June 30, 2007, the Company had 32,192,404 outstanding common shares. 4,240,500 warrants expired without being exercised.  Subsequent to the closing of two private placements, the Company has a total of 12,364,000 outstanding warrants exercisable at an exercise price range of $0.10 to $0.20 before the date of expiration. During the period, the Company received an approval from TSX to extend 3,916,000 warrants granted pursuant to private placement by a year to December 21, 2007 at the same exercise price of $0.10 per share.  The outstanding stock options as at June 30, 2007 were 2,480,000 with a weighted average exercise of $0.11 per options. There is no guarantee that the Company will derive any proceeds from the exercise of outstanding warrants and there is no assurance that additional funding will be available to the Company to fulfill its business objectives.  There can be no assurance that the Company will be able to obtain adequate financing in the future or that the terms of such financing will be favourable.  Many of the Company products still require further development and laboratory testing in order to obtain required regulatory approvals.  A lack of funds will impair the ability of the Company to complete such tests.  A lack of funds will also impair the Companys ability to establish marketing and sales plans once the products have been approved for sale.  If adequate financing is not available when required, the Company may be required to delay, scale back or eliminate various activities and may be unable to continue in operation.  ALDA may seek such additional financing through debt or equity offerings, but there can be no assurance that such financing will be available on terms acceptable to the Company or at all.  Any equity offering will result in dilution to the ownership interests of the Companys shareholders and may result in dilution to the value of such interests.  1.8 Off-Balance Sheet Arrangements  The company is not aware of any off-balance sheet transactions requiring disclosure. 1.9 Transactions with Related Parties  a) During the 2007 year, the Company incurred consulting fees of $120,000 (2006: $120,000) to companies controlled by directors of the Company.  b) During the 2007 year, the Company incurred premises rent of $28,371 (2006: $30,912) to a company controlled by a director of the Company.  e) During the 2007 year, the Company incurred consulting fees of $60,000 (2006: $60,000) to a major shareholder of ALDA.  f) Included in $293,600 Subscriptions receivable are $105,000 owing by directors of the Company.  These transactions were measured at the exchange amount, which is the amount of consideration established and agreed to by the related parties.  Alda Pharmaceuticals Corp. 2007 20F/A Page 87

MANAGEMENT DISCUSSION AND ANALYSIS (MD&A) FOR THE YEAR ENDED JUNE 30, 2007  1.10 Fourth Quarter, 2007  During the fourth quarter ended June 30, 2007, there were no extraordinary events that affected the Company. Sales for the quarter were close to the average sales recorded per quarter for the last two years. A private placement for $800,000 was completed on June 7, 2007. There were no significant year-end adjustments except that certain comparative figures for the 2006 have been reclassified to conform to the presentation adopted for the 2007 year.  1.11 Proposed transactions  The company is not aware of any proposed transactions requiring disclosure.  1.12 Critical Accounting Estimates  The company is a venture issuer and is not required to provide critical accounting estimates.  1.13 Changes in Accounting Policies Including Initial Adoption  Effective July 1, 2001, the Company adopted the new recommendations of the Canadian Institute of Chartered Accountants Accounting Handbook Section 3870, Stock-based Compensation and Other Stock-based Payments ("CICA 3870"). During the year ended June 30, 2004, CICA 3870 was amended to require the use of the fair value-based method to account for stock options granted to employees. In accordance with the revised recommendations, the Company has prospectively applied the fair value-based method to all stock options granted to employees on or after July 1, 2003, whereby compensation cost is measured at fair value at the date of grant and is expensed over the vesting period.  Effective July 1, 2003, the Company adopted the recommendations of the Canadian Institute of Chartered Accountants Handbook, Section 3063, Impairment of long-lived assets ("CICA 3063"). The new recommendations were applied prospectively to all long-lived assets held for use by the Company after July 1, 2003.  The financial statements include a note providing reconciliation to United States Generally Accepted Accounting Standards (GAAS).  Patent application and development costs include all expenditures attributable to efforts by the Company to develop, and bring to commercial production a new product as well as to acquire legal protections for its proprietary products, such as trademarks and patents.  Such amounts are charged as an expense in the period incurred except in circumstances where the market and technical feasibility of the product have been established, and recovery of patent application and development costs can reasonably be regarded as assured and future values can be realized, in which case such costs are capitalized.  In the latter case, patent application and development costs are amortized on a systematic basis over the patent life of 20 years.  The carrying amount of intangible assets which are determined to have a finite useful life are amortized on a systematic basis over the useful life of 20 years.

(d) Internal Control Over Financial Reporting  The Companys management is responsible for establishing and maintaining adequate internal control over financial reporting.  Management has considered the effectiveness of design of the Companys internal controls and procedures over financial reporting and has noted several weaknesses in internal controls over financial reporting such as a lack of segregation of duties because of limited staff members. Management intends to initiate steps to remedy the noted shortcomings over the next fiscal year by carrying out a management assessment of the weakness with a view to improving areas where weaknesses exist and implementing procedures aimed at minimizing the risk of material error in its financial reporting.
