You should carefully consider the risks described below and the other information contained in this Prospectus before deciding to invest in shares of our common stock. THE COMPANY MAY NOT HAVE SUFFICIENT CASH FOR ITS CURRENT OPERATIONS AND IF IT IS UNABLE TO RAISE NEW CAPITAL OR GENERATE SUFFICIENT CASH FROM OPERATIONS IT WILL NOT BE ABLE TO FULFILL ITS FINANCIAL OBLIGATIONS. The Company has a working capital deficit, which was approximately $390 thousand at September 30, 2004 and approximately $903 thousand at March 31, 2005. During fiscal year 2005, the Company's cash requirements are expected to include primarily the funding of operating losses, the payment of outstanding accounts payable, the repayment of certain notes payable, the funding of operating capital to grow the Company's drugs of abuse testing products and services, and the continued funding for the development of its ORALscreen(R) product line. The Company is seeking additional capital and plans to raise an additional $8,000,000 during the remainder of Fiscal 2005. However, there can be no assurance that these financings will be achieved. If these financings were achieved, the Company would be able to fund current operations until profitability or cash flow breakeven, but only if its projected sales are achieved. Thereafter it will need additional funds for operations, product expansion and debt repayment. In the event of unforeseen circumstances affecting the economy and/or the Company, this cash flow projection may be proven inaccurate, and the Company will need additional funds for current operations as well as for its outstanding obligations sooner than currently anticipated. The Company can give no assurance that sources of funds will be available to fund its operations and other obligations. If financing is unavailable, it may default on its obligations, curtail operations or cease business altogether. WE HAVE SUSTAINED LOSSES IN THE PAST AND WE EXPECT TO REPORT LOSSES IN THE FUTURE; GOING CONCERN EXPLANATORY PARAGRAPH IN REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM. We have incurred substantial losses that have reduced our stockholder's equity and at times depleted our working capital. We funded our negative cash flows from 1999 to date primarily by the sale of additional equity and the placement of debt. We incurred losses of approximately $4.15 million during fiscal year 2002, $6.46 million during fiscal year 2003, $2.97 million during fiscal year 2004 and $1.82 million during the first half of fiscal year 2005. The losses in fiscal year 2002 were incurred primarily from expenses associated with the marketing of the new drug-testing kits and the development of test kits for diseases. Economic conditions during fiscal year 2003 and 2004 and current economic conditions have imposed significant constraints on capital raising and have caused actual operating revenues to remain at a lower than expected level during fiscal years 2003 and 2004 and the first half of fiscal year 2005. As a result of the Company's recurring losses from operations and working capital deficit, the report of its independent registered public accounting firm relating to the financial statements for fiscal year 2004 contains an explanatory paragraph stating substantial doubt about the Company's ability to continue as a going concern. Such report states that the ultimate outcome of this matter could not be determined as of the date of such report (December 8, 2004, except for Note 17 for which the date is December 17, 2004). PRINCIPAL SUPPLIER RISK Suppliers of two key components are, in each case, the current sole source for the Company. The inability to obtain components will have an adverse effect on the business, revenues and prospects of the Company. Although the Company has an inventory of these components, it may not last sufficiently long while the Company finds a new supplier. There is no assurance that a new supplier will be found for these components on a timely basis, or at all, if the current supplier ceases to sell to the Company. Although some of the parts and components used to manufacture our products are available from multiple sources, we currently purchase most of our components from single sources in an effort to obtain volume discounts. Lack of availability of any of these parts and components could result in production delays, increased costs, or costly redesign of our products. Any loss of availability of an essential system component could result in a material adverse change to our business, financial condition and results of operations. NO ASSURANCE FUTURE CAPITAL WILL BE AVAILABLE TO US; ADDITIONAL CAPITAL WILL DILUTE THE HOLDINGS OF OUR STOCKHOLDERS. If we need additional financing, we cannot give any assurance that it will be available, or if available, that it will be available on terms favorable to our stockholders. If funds are not available to satisfy any of our short-term and long-term operating requirements, we may limit or suspend our operations in the entirety or, under certain circumstances, seek protection from creditors. Our recent equity offerings resulted in the dilution of our then existing stockholders. It is possible that future financings may contain terms that could result in similar or more substantial dilution than has already been incurred by our stockholders from the sales of equity with warrants since fiscal year 1998. A SIGNIFICANT NUMBER OF OUR SHARES ARE ELIGIBLE FOR SALE AND THEIR SALE COULD FURTHER DEPRESS THE MARKET PRICE OF OUR STOCK. Sales of substantial amounts of our common stock (including shares issued upon exercise of outstanding options and warrants and shares issued upon conversion of convertible preferred shares) in the public market could depress the market price of our common stock. As of May 10, 2005, we had approximately 157 million shares outstanding and approximately 62 million shares committed or reserved for issuance upon exercise of options and warrants or conversion of convertible preferred shares. RISK OF DELISTING FROM AMEX IF AVITAR FAILS TO REGAIN COMPLIANCE WITH CONTINUED LISTING STANDARDS Avitar does not meet all the continued listing standards of The American Stock Exchange (AMEX) primarily because of its accumulated losses that have reduced shareholders' equity to a deficit. AMEX has accepted Avitar's Compliance Plan and granted an extension to July of 2005. However, Avitar is subject to periodic review by AMEX and its shares could be delisted if Avitar fails to regain compliance with the continued listing standards. WE DEPEND ON THE DRUG OF ABUSE SCREEN SYSTEMS We intend to continue to concentrate our efforts primarily on the development of the ORALscreen(R) drug of abuse detection systems and we will be dependent upon the successful development and marketing of those systems to generate revenues. Acceptance of our systems may be adversely affected by: - costs, - concerns related to accuracy or false positive reports, - a cultural resistance to the use of drug of abuse screening tests, - the effectiveness of competing drug of abuse screening tests. Any failure to achieve greater market acceptance of our systems will have a material adverse effect on our business, financial condition and results of operations. THE SUCCESS OF COMPETITIVE PRODUCTS COULD HAVE AN ADVERSE EFFECT ON OUR BUSINESS. The Drug of Abuse Testing industry is intensely competitive, although at present we have encountered only minimal direct competition in the rapid on-site (as opposed to laboratory) oral fluid drug testing market. The significant competitive factors in the industry include: - price, - convenience, - accuracy, - acceptance of new technologies, - user satisfaction, and - when applicable, government approval. We believe our ORALscreen(R) systems offer several distinct advantages over the use of blood or urine samples, including net cost savings, ease of use and non-invasiveness. However, the success of any competing alternative to the ORALscreen(R) systems for screening for drugs of abuse could have a material adverse effect on our business, financial condition and results of operations. Most of our competitors have substantially greater financial capabilities for product development and marketing than we currently do. These financial capabilities enable our competitors to market their systems in a more effective manner. SUBSTANTIAL REGULATION BY GOVERNMENT AGENCIES. Many of our products are subject to regulation by the Food and Drug Administration (the "FDA") and comparable agencies in various states and foreign countries requiring, among other things, pre-market approval or clearance of new medical or dental devices. In November 2000, the FDA proposed regulations that, although still not in effect, in the future may require a pre-market approval or clearance of our ORALscreen(R) products for sale to employers. In addition, Avitar is subject to inspections by the FDA at all times, and may be subject to inspections by state and foreign agencies. If the FDA believes that its legal requirements have not been fulfilled, it has extensive enforcement powers, including the ability to initiate action to physically seize products and/or to enjoin their manufacture and distribution, to require recalls of certain types of products, and to impose or seek to impose civil or criminal sanctions against individuals or companies. Such submissions and review by the FDA could take several years, after which there could be no assurance that approval would be granted. DEPENDENCE ON INTELLECTUAL PROPERTY; NO ASSURANCE AS TO PROTECTION OF INTELLECTUAL PROPERTY. Our ability to compete effectively with other companies will depend, in part, on our ability to maintain the proprietary nature of our technologies. We intend to rely substantially on unpatented proprietary information and know-how, and there can be no assurance that others will not develop such information and know-how independently or otherwise obtain access to our technology. Similarly, there can be no assurance that our proprietary technology will not infringe patents or other rights owned by others. If we are unable to adequately safeguard and exploit our methods and technologies, our ability to compete with other companies, a majority of which have greater financial, technological, human and other resources than the Company, our business would be materially adversely affected. RISK OF PRODUCT LIABILITY; LIMITED INSURANCE COVERAGE. The testing, marketing and sale of medical and dental products entails a risk of product liability claims by consumers and others. Avitar has maintained product liability insurance coverage and currently has such insurance in the amount of up to $5,000,000. This insurance will not cover liabilities caused by events occurring after such policy is terminated or claims made after 60 days following termination of the policy or in respect of events excluded from coverage. In the event of a successful suit against Avitar, lack or insufficiency of insurance coverage would have a material adverse effect on Avitar. Further, certain distributors of medical and dental products require minimum product liability insurance coverage as a condition precedent to purchasing or accepting products for distribution. Failure to satisfy such insurance requirements could impede the ability of Avitar to achieve broad distribution of its products, which would have a material adverse effect on Avitar. WE ARE DEPENDENT ON OUR MANAGEMENT AND KEY PERSONNEL TO SUCCEED. Our principal executive officers and key personnel have extensive knowledge of and experience with our products, the research and development efforts needed to improve them and the development of marketing and sales programs to increase their market penetration. The loss of the services of any of our executive officers or other key personnel, or our failure to attract and retain other skilled and experienced personnel, could have a material adverse effect on our ability to manufacture, sell and market our products. Such events would probably have a negative impact on our business and financial condition. BARRIERS TO TAKEOVER The Company is governed by the provisions of Section 203 of the Delaware General Corporation Law, an anti-takeover law. In general, the law prohibits a public Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. "Business combination" is defined to include mergers, asset sales and certain other transactions resulting in a financial benefit to the stockholders. An "interested stockholder" is defined as a person who, together with affiliates and associates, owns (or within the prior three years, did own) 15% or more of a corporation's voting stock. As a result of the application of Section 203, potential acquirers of the Company may be discouraged from attempting to effect an acquisition transaction with the Company, thereby possibly depriving holders of the Company's securities of certain opportunities to sell or otherwise dispose of such securities at above market prices pursuant to such transactions. In addition, in the event of certain changes of control of the Company (as defined in the Company's Equity Plan) outstanding options granted pursuant to the Company's Equity Plan will become immediately exercisable in full. Such acceleration of exercisability may also discourage potential acquirers of the Company. THE MARKET PRICE OF OUR STOCK HAS HISTORICALLY BEEN VOLATILE. The volatility of our common stock imposes a greater risk of capital losses on stockholders as compared to less volatile stocks. In addition, such volatility makes it difficult to ascribe a stable valuation to a stockholder's holdings of our common stock. Factors such as announcements of technological innovations, changes in marketing, product pricing and sales strategies or new products by our competitors, changes in domestic or foreign governmental regulations or regulatory approval processes, developments or disputes relating to patent or proprietary rights and public concern as to the reliability of the OralScreen systems or drug tests in general may have a significant impact on the market price of our common stock. Moreover, the possibility exists that the stock market (and in particular the securities of technology companies such as ours) could experience extreme price and volume fluctuations unrelated to operating performance.

Description of Relationship of Cornell Capital Partners, L.P. with Avitar The following information concerns (i) each selling shareholder's relationship to Avitar and (ii) how each selling shareholder acquired the shares to be sold in this offering. None of the selling shareholders have held a position or office, or had any other material relationship, with the Company, except as follows: SHARES ACQUIRED IN FINANCING TRANSACTIONS WITH AVITAR - - CORNELL CAPITAL PARTNERS, LP. Cornell Capital Partners, LP is the investor under the Securities Purchase Agreement and a holder of the Series E Convertible Preferred Stock and related Warrants. Yorkville Advisors, LLC is the general partner of Cornell Capital Partners. As general partner, Yorkville Advisors, LLC controls and makes all investment decisions for Cornell Capital Partners. Mark Angelo, the managing member of Yorkville Advisors, makes the investment decisions on behalf of and controls Yorkville Advisors. Cornell Capital Partners acquired all shares being registered in this offering in financing transactions with Avitar. Those transactions are explained below: - - SECURITIES PURCHASE AGREEMENT. On April 19, 2005, we entered into a Securities Purchase Agreement with Cornell Capital Partners. Pursuant to the Securities Purchase Agreement, we issued $750,000 of the Company's Series E Convertible Preferred Stock and Warrants to purchase 75,000 shares of the Company's common stock in exchange for gross proceeds of $750,000, of which $375,000 was paid in the first closing and a second tranche of $375,000 was paid on May 9, 2005. The $750,000 Series E Convertible Preferred Stock are convertible into common stock at the lesser of $0.08 per share or 80% of the average of the three (3) lowest closing bid prices for the ten (10) trading days immediately prior to the notice of conversion, subject to adjustments and limitations, and the Warrants are exercisable at $0.084 per share. The Series E Convertible Preferred Stock has a potential two-year term accruing dividends at 5% per year until automatic conversion on its second anniversary date, April 19, 2007. If Cornell Capital Partners chooses to have interest be payable in common stock of the Company, rather than cash, this could have a further dilutive impact on our stockholders and could cause our stock price to decline. At maturity, the Series E Convertible Preferred Stock will automatically convert into shares of common stock at the then market conversion price. We are registering 11,718,750 shares of common stock under this prospectus based on current market conversion prices under the Series E Convertible Preferred Stock and 2,034,375 Additional Conversion Shares for possible reductions of future market conversion prices and 1,171,875 Dividend Shares that may be issued in lieu of cash for accrued dividends. On April 19, 2005, prior to entering into the Securities Purchase Agreement referred to above, the parties entered into a Termination Agreement terminating a Standby Equity Distribution Agreement ("SEDA") and related agreements made as of February 1, 2005. If Cornell Capital Partners does not enter into a SEDA on identical terms within 90 days after all amounts payable under the Securities Purchase Agreement are satisfied, Cornell Capital Partners agreed to return to Avitar all fees received pursuant to the February 2005 SEDA. There are certain risks related to sales by Cornell Capital Partners, L.P. ("Cornell") including: > The shares will be issued based on a discount to market prices. As a result, the lower the stock price around the time Cornell is issued shares, the greater chance that Cornell receives more shares. This could result in substantial dilution to the interests of other holders of common stock. > To the extent Cornell sells its common stock, the common stock price may decrease due to the additional shares in the market. This could allow Cornell to sell greater amounts of common stock, the sales of which would further depress the stock price. > The significant downward pressure on the price of the common stock as Cornell sells material amounts of common stock could encourage short sales by third parties. This could place further downward pressure on the price of the common stock. PLAN OF DISTRIBUTION We are registering the common stock, including the common stock underlying the warrants and the shares of preferred stock on behalf of the selling stockholders. The common stock may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market prices, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected at various times in one or more of the following transactions, or in other kinds of transactions: - transactions on The American Stock Exchange or on any national securities exchange or U.S. inter-dealer system of a registered national securities association on which the common stock may be listed or quoted at the time of sale; - in the over-the-counter market; - in private transactions and transactions otherwise than on these exchanges or systems or in the over-the-counter market; - in connection with short sales of the shares; - by pledge to secure or in payment of debt and other obligations; - through the writing of options, whether the options are listed on an options exchange or otherwise; - in connection with the writing of non-traded and exchange-traded call options, in hedge transactions and in settlement of other transactions in standardized or over-the-counter options; or - through a combination of any of the above transactions. The selling stockholders and their successors, including their transferees, pledgees or donees or their successors, may sell the common stock directly to the purchasers or through underwriters, broker-dealers or agents, who may receive compensation in the form of discounts, concessions or commissions from the selling stockholders or the purchasers. These discounts, concessions or commissions as to any particular underwriter, broker-dealer or agent may be in excess of those customary in the types of transactions involved. In addition, any securities covered by this prospectus that qualify for sale pursuant to Rule 144 under the Securities Act may be sold pursuant to Rule 144 rather than pursuant to this prospectus. We entered into registration rights agreements for the benefit of the selling stockholders to register the common stock under applicable federal and state securities laws. The registration rights agreements provide for cross-indemnification of the selling stockholders and us and our respective directors, officers and controlling persons against specific liabilities in connection with the offer and sale of the common stock, including liabilities under the Securities Act. We will pay substantially all of the expenses incurred by the selling stockholders incident to the registration of the offering and sale of the common stock. The selling stockholders and any other persons participating in the sale or distribution of the shares will be subject to applicable provisions of the Exchange Act and the rules and regulations under such act, including, without limitation, Regulation M. These provisions may restrict certain activities of, and limit the timing of purchase and sales of any of the shares by, the selling stockholders or any other such person. Furthermore, under Regulation M, persons engaged in a distribution of securities are prohibited from simultaneously engaging in market making and certain other activities with respect to such securities for a specified period of time prior to the commencement of such distributions, subject to specified exceptions or exemptions. All of these limitations may affect the marketability of the shares. EXPERTS The financial statements incorporated by reference in this Registration Statement have been audited by BDO Seidman, LLP, an independent registered public accounting firm, to the extent and for the periods set forth in their report (which contains an explanatory paragraph regarding the Company's ablility to continue as a going concern) incorporated herein by reference, and are incorporated herein in reliance upon such report given upon the authority of said firm as experts in auditing and accounting. LEGAL MATTERS Certain legal matters with respect to the validity of the common stock will be passed upon for Avitar by Dolgenos Newman & Cronin LLP, New York, New York. STATEMENT OF INDEMNIFICATION The Company's Certificate of Incorporation, as amended, provides that a director will not be personally liable to the Company or its stockholders for monetary damages for the breach of his or her fiduciary duty of care as a director, including breaches that constitute gross negligence. By its terms and in accordance with the Delaware General Corporation Law ("DGCL"), however, this provision does not eliminate or limit the liability of a director of the Company (i) for breach of the director's duty of loyalty to the Company or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL (relating to unlawful payments of dividends or unlawful stock repurchases or redemptions) or (iv) for any improper benefit. This provision offers persons who serve on our board of directors protection against awards of monetary damages resulting from breaches of their duty of care (except as indicated above). As a result of this provision, our ability or our stockholder's ability to successfully prosecute an action against a director for a breach of his duty of care is limited. However, the provision does not affect the availability of equitable remedies such as an injunction or rescission based upon a director's breach of his duty of care. The SEC has taken the position that the provision will have no effect on claims arising under federal securities laws. Section 145 of the Delaware law grants corporations the right to indemnify their directors, officers, employees and agents in accordance with the provisions therein set forth. Our By-laws provide that we shall, subject to limited exceptions, indemnify our directors and executive officers to the fullest extent not prohibited by the Delaware law. Our By-laws provide further that we shall have the power to indemnify our other officers, employees and other agents as set forth in the Delaware law. Such indemnification rights include reimbursement for expenses incurred by such director, executive officer, other officer, employee or agent in advance of the final disposition of such proceeding in accordance with the applicable provisions of the Delaware law. We have entered into agreements with certain of our directors and officers pursuant to which we have agreed to indemnify such directors and officers to the fullest extent permitted under applicable law. In addition, we have purchased insurance containing customary terms and conditions as permitted by law on behalf of our directors and officers, which may cover liabilities under the Securities Act. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers and controlling persons pursuant to these provisions, or otherwise, Avitar has been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.
