PROSPECTUS SUMMARY

The following summary highlights selected information contained in this prospectus. This summary does not contain all the information you should consider before investing in our securities. Before making an investment decision, you should read the entire prospectus carefully, including the “Risk Factors” section, the financial statements and the notes to the financial statements.

Our Company

OXIS International, Inc. develops technologies and products to research, diagnose, treat and prevent diseases of oxidative stress associated with damage from free radical and reactive oxygen species. We derive our revenues primarily from sales of research diagnostic assays to research laboratories. Our diagnostic products include approximately 30 research assays to measure markers of oxidative stress. We hold the rights to three therapeutic classes of compounds in the area of oxidative stress, and have focused our commercialization programs in clinical cardiovascular markers, including MPO (myeloperoxidase) and GPx (glutathione peroxidase), as well as a potent antioxidant, Ergothioneine, that may be appropriate for sale over-the-counter as a dietary supplement. OXIS has acquired a 51% interest in and has the option to purchase the remaining 49% of BioCheck, Inc.

Oxidative stress is associated with an excess of free radicals, reactive oxygen species and a decrease in antioxidant levels resulting in the development of tissue or organ damage. Oxidative stress can cause tissue injury by triggering cell death or inciting a tissue-damaging inflammatory response. We have invested significant resources to build a substantial patent position on both our antioxidant therapeutic technologies and selected oxidative stress assays.

Our majority-held subsidiary, BioCheck, is a leading producer of clinical diagnostic assays, including high quality enzyme immunoassay research services and immunoassay kits for cardiac and tumor markers, infectious diseases, thyroid function, steroids, and fertility hormones designed to improve the accuracy, efficiency, and cost-effectiveness of in vitro (outside the body) diagnostic testing in clinical laboratories. BioCheck focuses primarily on the immunoassay segment of the clinical diagnostics market. BioCheck offers over 40 clinical diagnostic assays which it manufactures in its 15,000 square foot, U.S. Food and Drug Administration, or FDA, certified Good Manufacturing Practices device-manufacturing facility in Foster City, California.

In 1965, the corporate predecessor of OXIS, Diagnostic Data, Inc. was incorporated in the State of California. Diagnostic Data changed its state of incorporation to Delaware in 1972; and changed its name to DDI Pharmaceuticals, Inc. in 1985. In 1994, DDI Pharmaceuticals merged with International BioClinical, Inc. and Bioxytech S.A. and changed its name to OXIS International, Inc. Our principal executive offices were relocated to 323 Vintage Park Drive, Suite B, Foster City, California 94404 on February 15, 2006. Our telephone number is (650) 212-2568.

Recent Financing

On October 25, 2006, we entered into a securities purchase agreement with four accredited investors. At the closing of this financing, we sold and issued Secured Convertible Debentures and Series A, B, C, D, and E common stock warrants (referred to throughout this prospectus as the “warrants”) to the purchasers, and also entered into a registration rights agreement and a security agreement.
 
3
 
Pursuant to the terms of the securities purchase agreement, we issued debentures in an aggregate principal amount of $1,694,250 to the Purchasers. The debentures were issued with an original issue discount of 20.318%, and resulted in proceeds to us of $1,350,000. The debentures are convertible, at the option of the holders, at any time into shares of common stock at $0.35 per share, as adjusted in accordance with a full ratchet anti-dilution provision (referred to in this prospectus as the “conversion price”). Beginning on the first of the month following the earlier of the effective date of the registration statement to be filed pursuant to the registration rights agreement and February 1, 2007, we will amortize the debentures in equal installments on a monthly basis resulting in a complete repayment by the maturity date (the “Monthly Redemption Amounts”). The Monthly Redemption Amounts can be paid in cash or in shares, subject to certain restrictions. If we choose to make any Monthly Redemption Amount payment in shares of our common stock, the stock will be valued at a price per share that is the lesser of the conversion price then in effect and 85% of the weighted average price for the ten trading days prior to the due date of the Monthly Redemption Amount. For additional details regarding the terms and conditions of the debentures and warrants, see Exhibits 10.2 and 10.3 to our current report on Form 8-K filed with the SEC on October 26, 2006. The above description is qualified in its entirety by reference to the full text of these instruments.
 
The performance of our duties and obligations under the debentures are secured by substantially all of our assets under a security agreement. As additional security to the debenture holders, we have also pledged the shares we hold in our subsidiaries, including 51% of BioCheck, Inc., and all of the shares of capital stock of our wholly-owned subsidiaries, OXIS Therapeutics, Inc. and OXIS Isle of Man Limited. In addition, OXIS Therapeutics, Inc. and OXIS Isle of Man Limited have each provided the debenture holders with a subsidiary guarantee in which these subsidiaries have guaranteed the performance, at the parent level, of our obligations under the debentures. For additional details regarding the terms and conditions of the security agreement, see Exhibit 10.5 to our current report on Form 8-K filed with the SEC on October 26, 2006. The above description is qualified in its entirety by reference to the full text of this agreement.
 
On October 25, 2006 in conjunction with the issuance of the debentures, we also issued (1) five year Series A warrants to purchase an aggregate of 2,420,357 shares of common stock at an initial exercise price of $0.35 per share, (2) one year Series B warrants to purchase 2,420,357 shares of common stock at an initial exercise price of $0.385 per share, (3) two year Series C warrants to purchase an aggregate of 4,840,714 shares of common stock at an initial exercise price of $0.35 per share, (4) six year Series D warrants to purchase 2,420,357 shares of common stock have an initial exercise price of $0.35 per share, which become exercisable on a pro-rata basis only upon the exercise of the Series C warrants, and (5) six year Series E warrants to purchase 2,420,357 shares of common stock with an initial exercise price of $0.385 per share, which similar to the Series D warrants, become exercisable on a pro-rata basis only upon the exercise of the Series C warrants. The debenture holders were issued Series A, B, C, D and E warrants in proportion to the amounts invested by the debenture holders in our debentures. The initial exercise prices for each warrant are adjustable in accordance with a full ratchet anti-dilution provision and upon the occurrence of a stock split or a related event. For purposes of illustrating the effect of the anti-dilution provision, if for instance we offered and issued shares of our common stock in an offering at a price per share below the exercise price of any of the warrants, the exercise price of the applicable warrant would be adjusted to match the lower price per share in the offering, and the number of shares purchasable under the warrant would be adjusted upward, so that the aggregate exercise price would be equal to the aggregate exercise price of the applicable warrant before the anti-dilution adjustment was made. For additional details regarding the terms and conditions of the warrants, see Exhibit 10.3 to our current report on Form 8-K filed with the SEC on October 26, 2006. The above description is qualified in its entirety by reference to the full text of these instruments.

THE OFFERING
 
We are registering shares of our common stock for sale by the selling security holders identified in the section of this prospectus entitled “Selling Security Holders.” The shares included in the table identifying the selling security holders consist of:

·  
4,840,714 shares of common stock underlying the debentures issued in our private placement on October 25, 2006;
 
·  
9,681,429 shares of common stock underlying Series A, Series C and Series D common stock warrants issued in our private placement on October 25, 2006; and
 
·  
4,840,714 shares of common stock underlying Series B and Series E common stock warrants issued in our private placement on October 25, 2006.
 
We are registering a total of 19,362,857 shares of our common stock that may become issuable upon conversion of the debentures and exercise of the warrants by the selling security holders, assuming the full conversion and exercise of these securities for the maximum number of shares issuable. This amount represents approximately 43.5% of our current outstanding stock, based on 44,527,476 shares of common stock outstanding as of December 1, 2006, which excludes: (i) 96,230 shares of Series C preferred stock convertible into 27,800 shares of common stock, which are not being registered for resale; (ii) up to 6,738,789 shares of common stock reserved for issuance to employees, directors and consultants as outstanding stock options or available for issuance under our 2003 Stock Incentive Plan; (iii) warrants to purchase an aggregate of 712,500 shares of common stock at a price of $0.50 per share, which are not being registered for resale, (iv) warrants to purchase an aggregate of 1,127,969 shares of common stock at a price of $1.00 per share, which are not being registered for resale, (v) warrants to purchase an aggregate of 108,000 shares of common stock at a price of $0.39 per share, which are not being registered for resale, (vi) warrants to purchase an aggregate of 1,158,857 shares of common stock at a price of $0.35 per share, which are not being registered for resale, (vii) warrants to purchase an aggregate of 2,416,108 shares of common stock at a price of $0.20 per share, which are not being registered for resale, (viii) warrants to purchase an aggregate of 6,438,685 shares of common stock at a price of $0.66 per share, which were previously registered for resale, and (ix) warrants to purchase an aggregate of 6,438,681 shares of common stock at a price of $1.00 per share, which were previously registered for resale. Upon full conversion of the debentures and exercise of the warrants, assuming no issuance of additional shares by us, and no adjustments to the conversion price of the debentures or the exercise prices of the warrants, we would have a total of 63,890,333 shares of common stock issued and outstanding.
 
USE OF PROCEEDS
 
This prospectus relates to 19,362,857 shares of our common stock, which may be sold from time to time by the selling security holders. We will not receive any part of the proceeds from the sale of common stock by the selling security holders. However, in order for the selling security holders to obtain the common stock underlying the warrants held by them, the selling security holders must either exercise the warrants by paying us a cash exercise price, or exercise the warrants without cash by forfeiting underlying shares.

Up to 14,522,143 shares of common stock are issuable upon exercise of outstanding warrants issued pursuant to the October 25, 2006 private placement. Of these warrants, (i) 9,681,429 have an exercise price of $0.35 per share and (ii) 4,840,714 have an exercise price of $0.385 per share. As of the date of this prospectus, December , 2006, the last sale price of our common stock as quoted on the OTCBB was $0.xx per share. If all such warrants are fully exercised without using any applicable cashless exercise provisions and assuming no anti-dilution adjustment of the applicable exercise prices, we will receive approximately $5,252,175 in cash from the warrant holders. We anticipate that any proceeds received by us from the exercise of the warrants will be used by us for general corporate purposes. There can be no assurance that any warrants will be exercised, or that we will receive any proceeds from the exercise of warrants. If the quoted price of our common stock for the duration of the warrants does not justify exercise of the warrants by their holders, we may not receive any proceeds from the warrants.

SELLING SECURITY HOLDERS
 
This prospectus covers the offer and sale by the selling security holders of up to 4,840,714 shares of our common stock issuable upon conversion of debentures and an additional 14,522,143 shares of Common Stock issuable upon exercise of warrants. The terms of the warrants preclude the holders thereof from exercising such warrants if the exercise would result in the holder and/or its affiliates beneficially owning in excess of either 4.99% or 9.99%, as elected by the holder at the time of purchase of the warrants held by such holder, of our outstanding common stock following the exercise. Each warrant holder can waive this provision with respect to the warrants it holds by providing 61 days’ advance written notice to us.
 
Except as listed below, none of the selling security holders had a material relationship with us within the past three years.
 
We are required to pay the fees and expenses incurred by us incident to the registration of the shares under this registration statement of which this prospectus is a part. We have also agreed to indemnify certain of the selling security holders against losses, claims, damages and liabilities arising out of relating to any misstatements or omissions in this registration statement or prospectus, including liabilities under the Securities Act.
  
In the purchase agreements, each of the selling security holders represented that it had acquired the shares for investment purposes only and with no present intention of distributing those shares, except in compliance with all applicable securities laws. In addition, each of the selling security holders represented that it qualifies as an “accredited investor” as such term is defined in Rule 501 under the Securities Act.
 
The table below sets forth information concerning the resale of the shares of common stock by the selling security holders. We will not receive any proceeds from the resale of common stock issuable pursuant to conversion of the debentures by the selling security holders. We will receive proceeds from the warrants, if exercised. The following table also sets forth the name of each security holder who is offering the resale of shares of common stock for resale under this prospectus, the number of shares of common stock beneficially owned by each selling security holder, the number of shares of common stock that may be sold in this offering and the number of shares of common stock each selling security holder will own after the offering, assuming they sell all of the shares offered. The number and percentage of shares beneficially owned is determined in accordance with Rule 13d-3 of the Securities Exchange Act of 1934, and the information is not necessarily indicative of beneficial ownership for any other purpose. Under such rule, beneficial ownership includes any shares as to which the selling security holder has sole or shared voting power or investment power and also any shares the selling security holder has the right to acquire within 60 days.

settlement of short sales entered into after the date of the initial final prospectus covering the resale of common stock by the selling security holders;
  
·
 
broker-dealers may agree with the selling security holders to sell a specified number of such shares at a stipulated price per share;

The selling security holders may also sell shares under Rule 144 under the Securities Act, if available, rather than under this prospectus.
 
Broker-dealers engaged by the selling security holders may arrange for other broker-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling security holders (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with NASDR Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with NASDR IM-2440.
 
In connection with the sale of the common stock or interests therein, the selling security holders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling security holders may also sell shares of the common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling security holders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The selling security holders and any broker-dealers or agents that are involved in selling the shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each selling security holder has informed us that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the common stock. In no event shall any broker-dealer receive fees, commissions and markups which, in the aggregate, would exceed eight percent (8%).
 
We are required to pay certain fees and expenses incurred by us incident to the registration of the shares. We have agreed to indemnify the selling security holders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.
 
Because selling security holders may be deemed to be “underwriters” within the meaning of the Securities Act, they will be subject to the prospectus delivery requirements of the Securities Act. In addition, any securities covered by this prospectus which qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than under this prospectus. Each selling security holder has advised us that they have not entered into any written or oral agreements, understandings or arrangements with any underwriter or broker-dealer regarding the sale of the resale shares. There is no underwriter or coordinating broker acting in connection with the proposed sale of the resale shares by the selling security holders.
 
We agreed to keep this prospectus effective until the earlier of (i) the date on which the shares have been sold or may be resold by the selling security holders without registration and without regard to any volume limitations by reason of Rule 144(e) under the Securities Act or any other rule of similar effect or (ii) the expiration of twenty-four (24) months following the date on which the SEC initially declared the Registration Statement effective. The resale shares will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.
 
Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale shares may not simultaneously engage in market making activities with respect to the common stock for a period of two business days prior to the commencement of the distribution. In addition, the selling security holders will be subject to applicable provisions of the Exchange Act and its rules and regulations, including Regulation M, which may limit the timing of purchases and sales of shares of the common stock by the selling security holders or any other person. We will make copies of this prospectus available to the selling security holders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale.
 
We will not receive any part of the proceeds from the sale of these shares by any of the selling security holders although we may receive proceeds in the event that some or all of the warrants held by the selling security holders are exercised.
 
The selling security holders are not restricted as to the price or prices at which they may sell the shares of our common stock offered under this prospectus. Also, the selling security holders are not restricted as to the number of shares which may be sold at any one time.
 
There is no assurance that any of selling security holder will sell any or all of the shares described in this prospectus and may transfer, devise or gift these securities by other means not described in this prospectus.

 RISK FACTORS

 This investment involves a high degree of risk. Before you invest you should carefully consider the risks and uncertainties described below. If any of the following risks are realized, our business, operating results and financial condition could be harmed and the value of our stock could go down. This means you could lose all or a part of your investment.

Risks Related to Our Business
 
We operate in a rapidly changing environment that involves a number of risks, some of which are beyond our control. The following discussion highlights some of these risks and others are discussed elsewhere in this prospectus.

We will need to raise additional capital to fund our general and administrative expenses, and if we are unable to raise such capital, we will have to curtail or cease operations.
 
We had cash and cash equivalents of $21,000 at our parent level at September 30, 2006. We cannot access the cash held by our majority-held subsidiary, BioCheck, to pay for our operating expenses at the parent level, since currently BioCheck is not our wholly-owned subsidiary. We obtained debt financing in the amount of $1,350,000 on October 25, 2006 and are seeking additional equity financing to obtain sufficient funds to sustain operations, including our development and commercialization programs and purchase the remaining 49% share of BioCheck that we currently do not own. We have incurred significant obligations in relation to the termination of our former president and chief executive officer. We repaid debt including accrued interest and expenses in the amount of $426,000 to Fagan Capital and $209,000 to our former chief executive officer. If we are unable to raise additional capital in the first quarter of 2007, we may have to curtail or cease operations.  If we raise short term capital by incurring additional debt, we will have to obtain equity financing sufficient to repay such debt and accrued interest. Further, incurring additional debt may make it more difficult for us to successfully consummate future equity financings.

Restrictive provisions of the Securities Purchase Agreement signed with purchasers of debentures and warrants in our recent convertible debt and warrant financing may prohibit us from consummating an equity financing transaction.

Pursuant to the Securities Purchase Agreement entered into with four accredited purchasers on October 25, 2006, we are prohibited from issuing shares of common stock or securities convertible into common stock except pursuant to options issued under its stock option plan and other limited exceptions, until ninety days after the effective date of the registration statement that we are required to file in relation to the securities issued in our October 25, 2006 financing, unless the volume weighted average quoted price of our common stock for each of the twenty days immediately prior to any such issuance of equity securities is higher than $0.40 per share, subject to adjustment for stock splits. Given the recent price range of our common stock between $0.20 and $0.35, unless the price of our common stock increases significantly within the next six to seven months, we will be unable to raise additional funds through an equity financing. Under the Securities Purchase Agreement in our October 25, 2006 financing, the purchasers of the debentures have the right to participate in up to 100% of any future equity financing involving issuance of common stock or securities convertible into or exercisable for common stock that we undertake within one year after the effective date of the registration statement which we are required to file in relation to the securities issued in our October 25, 2006 financing. This provision may make potential investors reluctant to enter into term sheets with us for future equity transactions.

Repayment of recently issued debentures in shares and the exercise of recently issued warrants would cause substantial dilution to our stockholders and would likely to depress our stock price, making it more difficult for us to consummate future equity financings.

In our October 25, 2006 debenture financing with four accredited purchasers, we issued secured convertible debentures in an aggregate principal amount of $1,694,250. We also issued Series A, B, C, D, and E warrants to the purchasers of the debentures, which provide them the right to purchase of an aggregate of approximately 14.5 million shares of our common stock, at initial exercise prices ranging from $0.35 to $0.385 per share, subject to adjustment as provided in the warrants, including a full ratchet anti-dilution provision which will lower the exercise price in the event that we conduct a financing at a price per share below $0.35 or $0.385 per share, respectively. The Series D and E warrants are only exercisable on a pro rata basis, if the Series C warrants are exercised. The debentures were issued with an original issue discount of 20.318%, and resulted in proceeds to us of $1,350,000. The debentures are convertible, at the option of the holders, at any time into shares of common stock at $0.35 per share, as adjusted in accordance with a full ratchet anti-dilution provision (referred to in this prospectus as the “conversion price”). Beginning on the first of the month following the earlier of the effective date of the registration statement to be filed pursuant to the registration rights agreement and February 1, 2007, we will amortize the debentures in equal installments on a monthly basis resulting in a complete repayment by the maturity date (the “Monthly Redemption Amounts”). The Monthly Redemption Amounts can be paid in cash or in shares, subject to certain restrictions. If we choose to make any Monthly Redemption Amount payment in shares of common stock, the price per share is the lesser of the conversion price then in effect and 85% of the weighted average price for the ten trading days prior to the due date of the Monthly Redemption Amount.

Due to the floating conversion price of the debentures that applies when we choose to repay the debentures in shares, we would need to issue approximately ten million shares to the holders of the debentures, assuming that stock prices remain in their recent price range. The number of shares that we may have to issue to the debenture holders could increase significantly if our stock price declines from the current price range. In addition, we would have to issue approximately five million shares if the debenture holders exercise their Series A and B warrants, an additional approximately five million shares would be issued upon exercise of their Series C warrants and finally, an additional approximately five million shares would be issued upon exercise of their Series D and E warrants pro rata subsequent to the exercise of the Series C warrants. The future potential dilution due to exercise of the above warrants could be increased if the full ratchet anti-dilution provision applicable to the exercise price of the warrants is triggered. This future potential dilution would likely depress our stock price, making it difficult for us to consummate a future equity financing.

Restrictions on our ability to repay the debentures in shares rather than in cash may deplete our cash resources and will require future financings to avoid default.

Under the terms of the debentures we issued in October 2006, our right to make monthly redemption payments is conditioned upon several factors. Beginning on the first of the month following the earlier of the effective date of the registration statement to be filed pursuant to the registration rights agreement, and February 1, 2007, we are obligated to amortize the debentures in equal installments on a monthly basis resulting in a complete repayment by the maturity date either in cash or in shares. The monthly redemptions, if made in cash to all debenture holders would equal approximately $85,000 per month. We may not make the monthly redemption in shares if, among other conditions, the issuance of the shares to the debenture holders would cause any debenture holder to beneficially own in excess of either 9.99% or 4.99% of our total outstanding shares at that time (depending on the particular debenture holder, either the 9.99% or the 4.99% threshold applies). One of the debenture holders currently beneficially owns approximately 9% of our total outstanding shares. In addition, we may not make monthly redemption payments to any debenture holder in shares rather than cash if the daily trading volume for our common stock does not exceed 50,000 shares per trading day for a period of twenty trading days prior to any applicable date in question beginning after April 25, 2007. If we must make all or a substantial amount of its monthly redemption payments to the debenture holders in cash rather than shares, its cash reserves will be depleted and it will have to raise substantial additional capital to avoid default of the debentures.

As we have failed to make payments due to BioCheck under our Mutual Services Agreement, BioCheck could exercise its rights under the default provisions of that agreement to terminate the agreement and cease production of many of our research test kit assays.

As mentioned above, on June 23, 2006, we entered into a mutual services agreement with our majority owned subsidiary, BioCheck. Pursuant to the agreement, we agreed to pay BioCheck approximately $103,000 that we owed to BioCheck for services that BioCheck had provided to us during the nine months ended September 30, 2006. As of the date of this prospectus, we have not made that payment. If we receive written notice of breach of the mutual services agreement due to this non-payment, it will have 15 days to cure that breach. If we fail to cure the breach during the cure period, BioCheck would have the right to terminate the agreement. Pursuant to the agreement, BioCheck is manufacturing the bulk of our research assay test kits, assisting in packaging and shipping such research assay test kits to our customers, and undertaking research and development of certain new OXIS research assay test kits. If BioCheck ceases to perform services under the agreement, we will have to turn to third party suppliers for the manufacturing of its research assay test kits, where that is possible, and will likely have to cease research and development of new OXIS research assay test kits. There can be no assurance that possible third party suppliers of research assay test kits will be willing or able to manufacture our research assay test kits at competitive prices or at all, or that we would be able to pay for such services. Disruption or cessation of manufacturing due to the termination of the mutual services agreement would have immediate and deleterious effects on our future revenues.

We will need to raise additional capital in order to complete our acquisition of the outstanding shares of BioCheck that we do not own, which constitutes 49% of BioCheck’s issued and outstanding shares.

On September 19, 2005 we entered into a stock purchase agreement with BioCheck and the stockholders of BioCheck pursuant to which we undertook to purchase up to all of the outstanding shares of common stock of BioCheck for an aggregate purchase price of $6.0 million in cash. On December 6, 2005, pursuant to the terms of the stock purchase agreement with BioCheck, at the initial closing, we purchased an aggregate of fifty-one percent (51%) of the outstanding shares of common stock of BioCheck from each of the stockholders of BioCheck on a pro rata basis, for an aggregate of $3,060,000 in cash. Pursuant to the stock purchase agreement, we will use its reasonable best efforts to consummate a follow-on financing transaction to raise additional capital with which to purchase the remaining outstanding shares of BioCheck in one or more additional closings. The purchase price for any BioCheck shares purchased after the initial closing will be increased by an additional 8% per annum from the date of the initial closing through the date of such purchase. Under the terms of our purchase agreements with BioCheck and its stockholders, BioCheck’s earnings (specifically, its earnings before interest, taxes, depreciation and amortization expenses, or EBITDA), if any, will be used to repurchase the remaining outstanding BioCheck shares at one or more additional closings. There can be no assurance that BioCheck will generate any earnings in the next several years which would be sufficient to purchase additional shares of BioCheck pursuant to the stock purchase agreement. Even if BioCheck generates earnings, there can be no assurance that such earnings would be sufficient to complete our acquisition of the remaining 49% of BioCheck’s outstanding shares.

To avoid an increase in the purchase price of the remaining shares of BioCheck at the rate of 8% per annum, we would need to consummate a financing transaction to complete the acquisition of the remaining 49% of the outstanding shares of BioCheck. The successful completion of our acquisition of BioCheck in this manner is dependent upon obtaining financing on acceptable terms. No assurances can be given that we will be able to complete such a financing sufficient to undertake our acquisition of the outstanding shares of BioCheck on terms favorable to us, or at all. Any financing that we do undertake to finance the acquisition of BioCheck would likely involve dilution of our common stock if it is an equity financing, or will involve the assumption of significant debt by us.

We will need additional financing in order to complete our development and commercialization programs.

As of September 30, 2006, we had an accumulated deficit of approximately $67,301,000. We currently do not have sufficient capital resources to complete the development and commercialization of our antioxidant therapeutic technologies and oxidative stress assays, and no assurances can be given that we will be able to raise such capital in the future on terms favorable to us, or at all. The lack of availability of additional capital could cause us to cease or curtail our operations and/or delay or prevent the development and marketing of our potential products. In addition, we may choose to abandon certain issued United States and international patents that we consider to be of lesser importance to our strategic direction, in an effort to preserve our financial resources.

Our future capital requirements will depend on many factors including the following:
 
·
continued scientific progress in our research and development programs and the commercialization of additional products;
 
·
the cost of our research and development and commercialization activities and arrangements, including sales and marketing;
 
·
the costs associated with the scale-up of manufacturing;
 
·
the success of pre-clinical and clinical trials;
 
·
the establishment of and changes in collaborative relationships;
 
·
the time and costs involved in filing, prosecuting, enforcing and defending patent claims;
 
·
the time and costs required for regulatory approvals;
 
·
the acquisition of additional technologies or businesses;
 
·
technological competition and market developments; and
 
·
the cost of complying with the requirements of the Autorité des Marchés Financiers, or AMF, the French regulatory agency overseeing the Nouveau Marché in France.

We will need to raise additional capital to fund our development and commercialization programs. Our current capital resources are not sufficient to sustain operations and our development program with respect to our Ergothioneine as a nutraceutical supplement. We have granted a licensee exclusive worldwide rights, in certain defined areas of cardiovascular indications, to develop, manufacture and market BXT-51072 and related compounds from our library of such antioxidant compounds. The licensee is responsible for worldwide product development programs with respect to the licensed compounds. Due to the lack of financial resources, we ceased further testing of BXT-51072 but continue to review the possibility of further developing applications for BXT-51072 and related compounds outside of the areas defined in the license. However, further development and commercialization of antioxidant therapeutic technologies, oxidative stress assays or currently unidentified opportunities, or the acquisition of additional technologies or businesses, may require additional capital. The fact that further development and commercialization of a product or technology would require us to raise additional capital, would be an important factor in our decision to engage in such further development or commercialization. No assurances can be given that we will be able to raise such funds in the future on terms favorable to us, or at all.

If we complete our acquisition of BioCheck, our business could be materially and adversely affected if we fail to adequately integrate the operations of the two companies.

If we complete the acquisition of BioCheck as planned, and we do not successfully integrate the operations of the two companies, or if the benefits of the transaction do not meet the expectations of financial or industry analysts, the market price of our common stock may decline. The acquisition could result in the use of significant amounts of cash, dilutive issuances of equity securities, or the incurrence of debt or expenses related to goodwill and other intangible assets, any of which, or all taken together, could materially adversely affect our business, operating results and financial condition.

We may not be able to successfully integrate the BioCheck business into our existing business in a timely and non-disruptive manner, or at all. In addition, the acquisition may result in, among other things, substantial charges associated with acquired in-process research and development, future write-offs of goodwill that is deemed to be impaired, restructuring charges related to consolidation of operations, charges associated with unknown or unforeseen liabilities of acquired businesses and increased general and administrative expenses. Furthermore, the acquisition may not produce revenues, earnings or business synergies that we anticipate.  There can be no assurance that BioCheck will continue to manufacture our research assay test kits if that agreement is terminated.

In addition, in general, acquisitions such as these involve numerous risks, including:
 
·
difficulties in assimilating the operations, technologies, products and personnel of an acquired company;
 
·
risks of entering markets in which we have either no or limited prior experience;
 
·
diversion of management’s attention from other business concerns; and
 
·
potential loss of key employees of an acquired company.

The time, capital management and other resources spent on the acquisition, if it fails to meet our expectations, could cause our business and financial condition to be materially and adversely affected.

Our relocation plan could adversely affect our operations.

As part of our decision to acquire BioCheck, we implemented a relocation and integration plan, including a strategy to reduce our cost structure. In doing so, we significantly reduced our employee workforce from 15 full time employees to six at November 10, 2006, outsourced certain company functions and have taken other steps intended to reduce costs and improve efficiencies.  Our business may continue to be disrupted and adversely affected by this reduction in work force until we employ new personnel to replace certain open positions. We may also experience disruption to our business as a result of our move to new facilities. The payment of severance benefits resulting from employee terminations will cause us to utilize cash. There can be no assurances that we will be able to improve efficiencies and function properly following such reductions.

We may experience disruption or may fail to achieve any benefits in connection with the recent changes in executive management and in board membership.

During the second quarter of 2004, our former Chief Executive Officer retired, and during the third quarter of 2004 our Chief Operating and Financial Officer resigned from his position at our company. As a result, others who had limited experience within our senior management were appointed to serve as acting Chief Executive Officer, acting Chief Operating Officer and acting Chief Financial Officer. On February 28, 2005, the Board appointed Mr. Steven T. Guillen as our President and Chief Executive Officer, and as a member of our board. On January 6, 2006, we hired Michael D. Centron as our Vice President and Chief Financial Officer. On September 15, 2006, Mr. Guillen’s employment as President and Chief Executive Officer was terminated, and Marvin S. Hausman, M.D. was appointed our new President and Chief Executive Officer. On November 15, 2006 Michael Centron, our Vice President and Chief Financial Officer resigned. In addition, during 2004 and early 2005, following the acquisition of a then-majority interest in our company by Axonyx, eight directors resigned from our board resulting in a four-person board. During 2005 we added independent director John E. Repine, M.D., and Gary M. Post joined our board of directors on March 15, 2006, resulting in a six-person board. Timothy C. Rodell, M.D., declined to stand for re-election at the Annual Meeting of Stockholders held on August 1, 2006. All five directors currently serving on the board commenced their service on the board during the period of 2004 through the date hereof.
 
14
 
One impact of such changes has been to delay our sales promotions in the research assay market and in the development of Ergothioneine market opportunities. Further, we narrowed our strategic focus to concentrate resources, including discontinuing our Animal Health Profiling program. In addition, the decreased sales at our parent company level during the third quarter of 2006 are attributable to lower sales volume that was caused, in part, by the disruption arising from relocating our operations from Portland, Oregon to Foster City, California and consolidating our product offerings. There can be no assurances that these changes will not cause further disruptions in, or otherwise adversely affect, our business and results of operations.

If we fail to attract and retain key personnel, our business could suffer.

Our future depends, in part, on our ability to attract and retain key personnel. We may not be able to hire and retain such personnel at compensation levels consistent with our existing compensation and salary structure. We deferred the hiring of senior management personnel in order to allow our newly-engaged full time Chief Executive Officer to select such key personnel. We cannot predict whether we will be successful in finding suitable new candidates for our key management positions. On September 15, 2006, Mr. Guillen’s employment as President and Chief Executive Officer was terminated, and Marvin S. Hausman, M.D. was appointed our new President and Chief Executive Officer. On November 15, 2006, Michael Centron resigned as our Vice President and Chief Financial Officer. Dr. Hausman has assumed the role of chief financial and accounting officer on an interim basis. While we have entered into an employment agreement with Dr. Hausman, he is free to terminate his employment “at will.” Further, we cannot predict whether Dr. Hausman will be successful in his role as our President and Chief Executive Officer, or whether senior management personnel hires will be effective. The loss of services of executive officers or key personnel, any transitional difficulties with our new Chief Executive Officer or the inability to attract qualified personnel could have a material adverse effect on our financial condition and business. As we currently do not have a Chief Financial Officer, it is crucial that we find a qualified individual to fill that role and to oversee and certify the periodic reports we must file with the Securities and Exchange Commission. As we currently have limited cash resources, if any of our key personnel leaves, replacing them will be difficult. We do not have any key employee life insurance policies with respect to any of our executive officers.

The success of our business depends upon our ability to successfully develop and commercialize products.

We cannot assure you that our efforts to develop and commercialize a cardiac predictor product, an Ergothioneine nutraceutical product or any other products will be successful. The cost of such development and commercialization efforts can be significant and the likelihood of success of any such programs is difficult to predict. The failure to develop or commercialize such new products could be materially harmful to us and our financial condition.
 
15
 
Our future profitability is uncertain.

We cannot predict our ability to reduce our costs or achieve profitability. We may be required to increase our research and development expenses in order to develop potential new products. As evidenced by the substantial net losses during and the first six months of 2006 and in fiscal year 2005, losses and expenses may increase and fluctuate from quarter to quarter. There can be no assurance that we will ever achieve profitable operations.

We have no biopharmaceutical or clinical diagnostic products available for sale and we may not be able to successfully develop products suitable for commercialization.

All of our biopharmaceutical and clinical diagnostic candidates are at an early stage of development and all of such therapeutic and clinical diagnostic candidates will require expensive and lengthy testing and regulatory clearances. None of our therapeutic or clinical diagnostic candidates have been approved by regulatory authorities. We have no therapeutic or clinical diagnostic products available for sale and we may not have any products commercially available for several years, if at all. There are many reasons we may fail in our efforts to develop our therapeutic and clinical diagnostic candidates, including:
 
·
our therapeutic and clinical diagnostic candidates may be ineffective, toxic or may not receive regulatory clearances,
 
·
our therapeutic and clinical diagnostic candidates may be too expensive to manufacture or market or may not achieve broad market acceptance,
 
·
third parties may hold proprietary rights that may preclude us from developing or marketing our therapeutic and clinical diagnostic candidates, or
 
·
third parties may market equivalent or superior products.

Clinical development is inherently uncertain and expense levels may fluctuate unexpectedly because we cannot accurately predict the timing and level of such expenses.

Our future success may depend in part upon the results of clinical trials undertaken by us or our licensees designed to assess the safety and efficacy of our potential products. We do not have substantial experience in developing and running clinical trials. The completion of clinical trials often depends significantly upon the rate of patient enrollment, and our expense levels will vary depending upon the rate of enrollment. In addition, the length of time necessary to complete clinical trials and submit an application for marketing and manufacturing approvals varies significantly and is difficult to predict. The expenses associated with each phase of development depend upon the design of the trial. The design of each phase of trials depends in part upon results of prior phases, and additional trials may be needed at each phase. As a result, the expense associated with future phases cannot be predicted in advance. Further, if we undertake clinical trials, we may decide to terminate or suspend ongoing trials. Failure to comply with extensive FDA regulations may result in unanticipated delay, suspension or cancellation of a trial or the FDA’s refusal to accept test results. The FDA may also suspend our clinical trials at any time if it concludes that the participants are being exposed to unacceptable risks. As a result of these factors, we cannot predict the actual expenses that we will incur with respect to clinical trials for any of our potential products, and we expect that our expense levels will fluctuate unexpectedly in the future.

Competition in most of our primary current and potential market areas is intense and expected to increase.

The diagnostic, pharmaceutical and nutraceutical industries are highly competitive. The main commercial competition at present in our research assay business is represented by, but not limited to, the following companies: Cayman Chemical Company, Assay Designs and Randox Laboratories Ltd. In addition, our competitors and potential competitors include large pharmaceutical/nutraceutical companies, universities and research institutions. Compared to us, these competitors may have substantially greater capital resources, research and development staffs, facilities, as well as greater expertise manufacturing and making products. In addition, these companies, as well as others, may have or may develop new technologies or use existing technologies that are, or may in the future be, the basis for competitive products. There can be no assurance that we can compete successfully.
 
16
 
In addition, current and potential competitors may make strategic acquisitions or establish cooperative relationships among themselves or with third parties, thereby increasing the ability of their products to address the needs of our current and prospective customers. Accordingly, it is possible that new competitors or alliances among current and new competitors may emerge and rapidly gain significant market share. Such competition could materially adversely affect our ability to commercialize existing technologies or new technologies on terms favorable to us. Further, competitive pressures could require us to reduce the price of our products and technologies, which could materially adversely affect our business, operating results and financial condition. We may not be able to compete successfully against current and future competitors and any failure to do so would have a material adverse effect upon our business, operating results and financial condition.

TorreyPines Therapeutics, Inc. holds significant stockholder voting power, and may be in a position to influence matters affecting us.

TorreyPines Therapeutics, Inc. or TorreyPines, which merged with Axonyx Inc. in October 2006, currently owns approximately 32% of our issued and outstanding stock. In addition, Dr. Marvin Hausman is a member of the board of directors of TorreyPines and is our President and Chief Executive Officer and the chairman of our board of directors. Given these circumstances, TorreyPines may influence our business direction and policies, and, thus, may have the ability to control certain material decisions affecting us. In addition, such concentration of voting power could have the effect of delaying, deterring or preventing a change of control or other business combination that might otherwise be beneficial to our stockholders. Section 203 of the Delaware General Corporation Law prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years unless the transaction meets certain conditions. Section 203 also limits the extent to which an interested stockholder can receive benefits from our assets. These provisions could complicate or prohibit certain transactions (including a financing transaction between us and TorreyPines), or limit the price that other investors might be willing to pay in the future for shares of our common stock.

If we are unable to develop and maintain alliances with collaborative partners, we may have difficulty developing and selling our products and services.

Our ability to realize significant revenues from new products and technologies is dependent upon, among other things, our success in developing business alliances and licensing arrangements with nutraceutical, biopharmaceutical and/or health related companies to develop and market these products. To date, we have had limited success in establishing foundations for such business alliances and licensing arrangements and there can be no assurance that our efforts will result in the development of mature relationships or that any such relationships will be successful. Further, relying on these or other alliances is risky to our future success because:
 
·
our partners may develop products or technologies competitive with our products and technologies;
 
·
our partners may not devote sufficient resources to the development and sale of our products and technologies;
 
·
our collaborations may be unsuccessful; or
 
17
 
·
we may not be able to negotiate future alliances on acceptable terms.

Our revenues and quarterly results have fluctuated historically and may continue to fluctuate, which could cause our stock price to decrease.

Our revenues and operating results may fluctuate due in part to factors that are beyond our control and which we cannot predict. Material shortfalls in revenues will materially adversely affect our results and may cause us to experience losses. In particular, our revenue growth and profitability depend on sales of our research assays and fine chemicals. Factors that could cause sales for these products and other products to fluctuate include:
 
·
an inability to produce products in sufficient quantities and with appropriate quality;
 
·
an inability to obtain sufficient raw materials;
 
·
the loss of or reduction in orders from key customers;
 
·
variable or decreased demand from our customers;
 
·
the receipt of relatively large orders with short lead times;
 
·
our customers’ expectations as to how long it takes us to fill future orders;
 
·
customers’ budgetary constraints and internal acceptance review procedures;
 
·
there may be only a limited number of customers that are willing to purchase our research assays and fine chemicals;
 
·
a long sales cycle that involves substantial human and capital resources; and
 
·
potential downturns in general or in industry specific economic conditions.

Each of these factors has impacted, and may in the future impact, the demand for and availability of our products and our quarterly operating results. For example, due to the unavailability of beef liver as a source for bSOD we were unable to sell any bSOD during 2005 and 2004, as compared to sales of $562,000 in 2003. We do not anticipate this source becoming available again within the foreseeable future and do not anticipate any revenues from sales of this product in the foreseeable future. In addition, a decrease in the demand for our Ergothioneine product resulted in a reduction of sales of Ergothioneine to $18,000 in 2005 and $87,000 in 2004, compared to $333,000 in 2003. We cannot predict with any certainty our future sales of Ergothioneine.

If the sales or development cycles for research assays and fine chemicals lengthen unexpectedly, our revenues may decline or not grow as anticipated and our results from operations may be harmed.

Changes in accounting standards regarding stock option plans could increase our reported losses, cause our stock price to decline and limit the desirability of granting stock options.

In December 2004, the FASB issued SFAS 123R. SFAS 123R replaces SFAS No. 123 and supersedes APB Opinion No. 25. SFAS 123R establishes standards for the accounting for share-based payment transactions in which an entity exchanges its equity instruments for goods or services. It also addresses transactions in which an entity incurs liabilities in exchange for goods or services that are based on the fair value of the entity’s equity instruments or that may be settled by the issuance of those equity instruments. SFAS 123R covers a wide range of share-based compensation arrangements including share options, restricted share plans, performance-based awards, share appreciation rights and employee share purchase plans. SFAS 123R requires a public entity to measure the cost of employee services received in exchange for an award of equity instruments based on the fair value of the award on the grant date (with limited exceptions). That cost will be recognized in the entity’s financial statements over the period during which the employee is required to provide services in exchange for the award. Management implemented SFAS 123R effective January 1, 2006. Expensing such stock options will add to our losses or reduce our profits, if any. In addition, stock options are an important employee recruitment and retention tool, and we may not be able to attract and retain key personnel if we reduce the scope of our employee stock option program.

Our income may suffer if we receive relatively large orders with short lead times, or our manufacturing capacity does not otherwise match our demand.

Because we cannot immediately adapt our production capacity and related cost structures to rapidly changing market conditions, when demand does not meet our expectations, our manufacturing capacity will likely exceed our production requirements. Fixed costs associated with excess manufacturing capacity could adversely affect our income. Similarly, if we receive relatively large orders with short lead times, we may not be able to increase our manufacturing capacity to meet product demand, and, accordingly, we will not be able to fulfill orders in a timely manner. During a market upturn, we may not be able to purchase sufficient supplies to meet increasing product demand. In addition, suppliers may extend lead times, limit supplies or increase prices due to capacity constraints or other factors. These factors could materially and adversely affect our results.

Our success will require that we establish a strong intellectual property position and that we can defend ourselves against intellectual property claims from others.

Maintaining a strong patent position is important to us in order to establish and maintain a competitive advantage. We currently have 81 patents either granted or applied for in 16 countries with expiration dates ranging from 2009 to 2025. Litigation on patent-related matters has been prevalent in our industry and we expect that this will continue. Patent law relating to the scope of claims in the technology fields in which we operate is still evolving and the extent of future protection is highly uncertain, so there can be no assurance that the patent rights we have or may obtain will be valuable. Others may have filed, or may in the future file, patent applications that are similar or identical to ours. To determine the priority of inventions, we may have to participate in interference proceedings declared by the United States Patent and Trademark Office that could result in substantial costs in legal fees and could substantially affect the scope of our patent protection. We cannot assure investors that any such patent applications will not have priority over our patent applications. Further, we may choose to abandon certain issued United States and international patents that we consider to be of lesser importance to our strategic direction, in an effort to preserve our financial resources. Abandonment of patents could substantially affect the scope of our patent protection. In addition, we may in future periods incur substantial costs in litigation to defend against patent suits brought by third parties or if we initiate such suits.
 
19
 
In addition to patent protection, we also rely upon trade secret protection for our confidential and proprietary information. There can be no assurance, however, that such measures will provide adequate protection for our trade secrets or other proprietary information. In addition, there can be no assurance that trade secrets and other proprietary information will not be disclosed, that others will not independently develop substantially equivalent proprietary information and techniques or otherwise gain access to or disclose our trade secrets and other proprietary information. If we cannot obtain, maintain or enforce our intellectual property rights, competitors may seize the opportunity to design and commercialize competing technologies.

We may face challenges from third parties regarding the validity of our patents and proprietary rights, or from third parties asserting that we are infringing their patents or proprietary rights, which could result in litigation that would be costly to defend and could deprive us of valuable rights.

Extensive litigation regarding patents and other intellectual property rights has been common in the biotechnology and pharmaceutical industries. The defense and prosecution of intellectual property suits, United States Patent and Trademark Office interference proceedings, and related legal and administrative proceedings in the United States and internationally involve complex legal and factual questions. As a result, such proceedings are costly and time-consuming to pursue and their outcome is uncertain. Litigation may be necessary to:
 
·
enforce patents that we own or license;
 
·
protect trade secrets or know-how that we own or license; or
 
·
determine the enforceability, scope and validity of the proprietary rights of others.

Our involvement in any litigation, interference or other administrative proceedings could cause us to incur substantial expense and could significantly divert the efforts of our technical and management personnel. An adverse determination may subject us to loss of our proprietary position or to significant liabilities, or require us to seek licenses that may not be available from third parties. An adverse determination in a judicial or administrative proceeding, or a failure to obtain necessary licenses, may restrict or prevent us from manufacturing and selling our products. Costs associated with these arrangements may be substantial and may include ongoing royalties. Furthermore, we may not be able to obtain the necessary licenses on satisfactory terms, if at all. These outcomes could materially harm our business, financial condition and results of operations.

We may be exposed to liability due to product defects.

The risk of product liability claims is inherent in the testing, manufacturing, marketing and sale of our products. We may seek to acquire additional insurance for liability risks. We may not be able to obtain such insurance or general product liability insurance on acceptable terms or in sufficient amounts. A product liability claim or recall could have a serious adverse effect on our business, financial condition and results of operations.

Disclosure controls are no assurance that the objectives of the control system are met.

Although we have an extensive operating history, resources are limited for the development and maintenance of our control environment. We have a very limited number of personnel and therefore segregation of duties can be somewhat limited as to their scope and effectiveness. We believe, however, that we are in reasonable compliance with the best practices given the environment in which we operate. Although existing controls in place are deemed appropriate for the prevention, detection and minimization of fraud, theft and errors, they may result in only limited assurances, at best, that the total objectives of the control system are met. Due to the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, can be detected and/or prevented and as such this is a risk area for investors to consider.

Risks Related to Our Common Stock
 
Our common stock is traded on the OTCBB, our stock price is highly volatile, and you may not be able to sell your shares of our common stock at a price greater than or equal to the price you paid for such shares.

Our shares of common stock are currently traded on the Over the Counter Bulletin Board, or OTCBB. Stocks traded on the OTCBB generally have limited trading volume and exhibit a wide spread between bid and ask quotations. The market price of our common stock is extremely volatile. To demonstrate the volatility of our stock price, during the nine-month period ending on September 30, 2006, the volume of our common stock traded on any given day ranged from 0 to 2,786,900 shares. Moreover, during that period, our common stock traded as low as $0.21 per share and as high as $0.46 per share, a 119% difference. This may impact an investor’s decision to buy or sell our common stock. As of September 30, 2006 there were approximately 5,200 holders of our common stock. Factors affecting our stock price include:
 
·
our financial results;
 
·
fluctuations in our operating results;
 
·
announcements of technological innovations or new commercial health care products or therapeutic products by us or our competitors;
 
·
government regulation;
 
·
developments in patents or other intellectual property rights;
 
·
developments in our relationships with customers and potential customers; and
 
·
general market conditions.

Furthermore, volatility in the stock price of other companies has often led to securities class action litigation against those companies. Any such securities litigation against us could result in substantial costs and divert management’s attention and resources, which could seriously harm our business and financial condition.

Our common stock may be subject to “penny stock” rules which may be detrimental to investors.

Our common stock may be, or may become, subject to the regulations promulgated by the SEC for “penny stock.” SEC regulation relating to penny stock is presently evolving, and the OTCBB may react to such evolving regulation in a way that adversely affects the market liquidity of our common stock. Penny stock currently includes any non-NASDAQ equity security that has a market price of less than $5.00 per share, subject to certain exceptions. The regulations require that prior to any non-exempt buy/sell transaction in a penny stock, a disclosure schedule set forth by the SEC relating to the penny stock market must be delivered to the purchaser of such penny stock. This disclosure must include the amount of commissions payable to both the broker-dealer and the registered representative and current price quotations for the common stock. The regulations also require that monthly statements be sent to holders of penny stock that disclose recent price information for the penny stock and information of the limited market for penny stocks. These requirements may adversely affect the market liquidity of our common stock.
 
21
 
Sales of our common stock may require broker-dealers to make special suitability determinations regarding prospective purchasers.

Our common stock may be, or may become, subject to Rule 15g-1 through 15g-9 under the Exchange Act, which imposes certain sales practice requirements on broker-dealers which sell our common stock to persons other than established customers and “accredited investors” (generally, individuals with a net worth in excess of $1,000,000 or an annual income exceeding $200,000 (or $300,000 together with their spouses)). For transactions covered by this rule, a broker-dealer must make a special suitability determination for the purchaser and have received the purchaser’s written consent to the transaction prior to the sale. Applicability of this rule would adversely affect the ability of broker-dealers to sell our common stock and purchasers of our common stock to sell their shares of such common stock. Accordingly, the market for our common stock may be limited and the value negatively impacted.

We will incur expenses in connection with registration of our shares which may be significant.

We are required to pay fees and expenses incident to the registration with the SEC of the shares issued in the private placement of equity which closed on January 6, 2005 and maintain adequate disclosure in connection with such registration, including updating prospectuses and under certain circumstances, filing amended registration statements. These expenses were $302,000 in 2005, and we may incur significant additional expenses in the future related to maintaining effective registration statements for prior financings and any additional registrations related to future financings. We have also agreed to indemnify such selling security holders against losses, claims, damages and liabilities arising out of relating to any misstatements or omissions in our registration statement and related prospectuses, including liabilities under the Securities Act. In the event such a claim is made in the future, such losses, claims, damages and liabilities arising therefrom could be significant in relation to our revenues.

A large number of additional shares may be sold into the public market in the near future, which may cause the market price of our common stock to decline significantly, even if our business is successful.

Sales of a substantial amount of common stock in the public market, or the perception that these sales may occur, could adversely affect the market price of our common stock. After our October 25, 2006 debenture and warrant financing, and assuming the full conversion of the debentures and full exercise of the Series A, B, C, D and E warrants for the maximum number of shares for which such warrants are exercisable, we would have approximately [63,890,333] shares of common stock outstanding. Upon full issuance of these shares of common stock upon conversion of the debentures and exercise of the warrants, the market price of our common stock could drop significantly if the holders of these shares sell them or are perceived by the market as intending to sell them.
 
A large number of common shares are issuable upon exercise of outstanding common share warrants and upon conversion of our outstanding debentures. The exercise or conversion of these securities could result in the substantial dilution of your investment in terms of your percentage ownership in OXIS as well as the book value of your common shares. The sale of a large amount of common shares received upon exercise of these warrants on the public market to finance the exercise price or to pay associated income taxes, or the perception that such sales could occur, could substantially depress the prevailing market prices for our shares.

As of December 1, 2006, there are outstanding warrants entitling the holders to purchase up to a maximum of 9,681,840 common shares at an exercise price of $0.35 per share. In addition, there are outstanding warrants entitling the holders to purchase up to a maximum of 4,840,740 common shares at an exercise price of $0.385 per share. There are also debentures outstanding which are convertible into a maximum of 4,840,740 common shares at a conversion price per common share of $0.35 per common share. The exercise price for all of the aforesaid warrants may be less than your cost to acquire our common shares. In the event of the exercise and/or conversion of these securities, you could suffer substantial dilution of your investment in terms of your percentage ownership in the company as well as the book value of your common shares. In addition, the holders of the common share purchase warrants may sell common shares in tandem with their exercise of those warrants to finance that exercise, or may resell the shares purchased in order to cover any income tax liabilities that may arise from their exercise of the warrants.
 
22
 
If we fail to maintain the adequacy of our internal controls, our ability to provide accurate financial statements and comply with the requirements of the Sarbanes-Oxley Act of 2002 could be impaired, which could cause our stock price to decrease substantially.

We are continuing to take measures to address and improve our financial reporting and compliance capabilities and we are in the process of instituting changes to satisfy our obligations in connection with being a public company. We plan to obtain additional financial and accounting resources to support and enhance our ability to meet the requirements of being a public company. We will need to continue to improve our financial and managerial controls, reporting systems and procedures, and documentation thereof. If our financial and managerial controls, reporting systems or procedures fail, we may not be able to provide accurate financial statements on a timely basis or comply with the Sarbanes-Oxley Act of 2002 as it applies to us. Any failure of our internal controls or our ability to provide accurate financial statements could cause the trading price of our common stock to decrease substantially.

Our common shares are thinly traded and, if you are a holder of debentures, you may be unable to sell at or near ask prices or at all if you need to convert your debentures into common stock and sell your shares to raise money or otherwise desire to liquidate such shares.

We cannot predict the extent to which an active public market for our common stock will develop or be sustained. Our common shares have historically been sporadically or “thinly-traded” on the “Over-The-Counter Bulletin Board,” meaning that the number of persons interested in purchasing our common shares at or near bid prices at any given time may be relatively small or non-existent. This situation is attributable to a number of factors, including the fact that we are a small company which is relatively unknown to stock analysts, stock brokers, institutional investors and others in the investment community that generate or influence sales volume, and that even if we came to the attention of such persons, they tend to be risk-averse and would be reluctant to follow an unproven company such as ours or purchase or recommend the purchase of our shares until such time as we became more seasoned and viable. As a consequence, there may be periods of several days or more when trading activity in our shares is minimal or non-existent, as compared to a seasoned issuer which has a large and steady volume of trading activity that will generally support continuous sales without an adverse effect on share price. We cannot give you any assurance that a broader or more active public trading market for our common stock will develop or be sustained, or that current trading levels will be sustained.

The market price for our common stock is particularly volatile given our status as a relatively small company with a small and thinly traded “float” and lack of current revenues that could lead to wide fluctuations in our share price. The price at which you convert your debentures into our common stock many be indicative of the price that will prevail in the trading market. You may be unable to sell your common stock at or above your purchase price if at all, which may result in substantial losses to you.

The market for our common shares is characterized by significant price volatility when compared to seasoned issuers, and we expect that our share price will continue to be more volatile than a seasoned issuer for the indefinite future. The volatility in our share price is attributable to a number of factors. First, as noted above, our common shares are sporadically and/or thinly traded. As a consequence of this lack of liquidity, the trading of relatively small quantities of shares by its shareholders may disproportionately influence the price of those shares in either direction. The price for its shares could, for example, decline precipitously in the event that a large number of our common shares are sold on the market without commensurate demand, as compared to a seasoned issuer which could better absorb those sales without adverse impact on its share price. Secondly, an investment in us is a speculative or “risky” investment due to our lack of revenues or profits to date and uncertainty of future market acceptance for current and potential products. As a consequence of this enhanced risk, more risk-adverse investors may, under the fear of losing all or most of their investment in the event of negative news or lack of progress, be more inclined to sell their shares on the market more quickly and at greater discounts than would be the case with the stock of a seasoned issuer.
 
23
 
Investors should be aware that, according to SEC Release No. 34-29093, the market for penny stocks has suffered in recent years from patterns of fraud and abuse. Such patterns include (1) control of the market for the security by one or a few broker-dealers that are often related to the promoter or issuer; (2) manipulation of prices through prearranged matching of purchases and sales and false and misleading press releases; (3) boiler room practices involving high-pressure sales tactics and unrealistic price projections by inexperienced sales persons; (4) excessive and undisclosed bid-ask differential and markups by selling broker-dealers; and (5) the wholesale dumping of the same securities by promoters and broker-dealers after prices have been manipulated to a desired level, along with the resulting inevitable collapse of those prices and with consequent investor losses. Our management is aware of the abuses that have occurred historically in the penny stock market. Although we do not expect to be in a position to dictate the behavior of the market or of broker-dealers who participate in the market, management will strive within the confines of practical limitations to prevent the described patterns from being established with respect to our securities. The occurrence of these patterns or practices could increase the volatility of our share price.

We do not anticipate paying any cash dividends.

We presently do not anticipate that we will pay any dividends on any of our capital stock in the foreseeable future. The payment of dividends, if any, would be contingent upon our revenues and earnings, if any, capital requirements, and general financial condition. The payment of any dividends will be within the discretion of our board of directors. We presently intend to retain all earnings, if any, to implement our business plan; accordingly, we do not anticipate the declaration of any dividends in the foreseeable future.

BUSINESS

Overview

We develop technologies and products to research, diagnose, treat and prevent diseases of oxidative stress associated with damage from free radical and reactive oxygen species. We derive our revenues primarily from sales of research diagnostic assays to research laboratories. Our diagnostic products include approximately 30 research assays to measure markers of oxidative stress. We hold the rights to three therapeutic classes of compounds in the area of oxidative stress, and have focused our commercialization programs in clinical cardiovascular markers, including MPO (myeloperoxidase) and GPx (glutathione peroxidase), as well as a potent antioxidant, Ergothioneine, that may be appropriate for sale over-the-counter as a dietary supplement. We have acquired a 51% interest in and has the option to purchase the remaining 49% of BioCheck, Inc.

Our majority-held subsidiary, BioCheck, Inc. is a leading producer of clinical diagnostic assays, including high quality enzyme immunoassay research services and immunoassay kits for cardiac and tumor markers, infectious diseases, thyroid function, steroids, and fertility hormones designed to improve the accuracy, efficiency, and cost-effectiveness of in vitro (outside the body) diagnostic testing in clinical laboratories. BioCheck focuses primarily on the immunoassay segment of the clinical diagnostics market. BioCheck offers over 40 clinical diagnostic assays manufactured in its 15,000 square-foot, U.S. Food and Drug Administration, or FDA, certified Good Manufacturing Practices device-manufacturing facility in Foster City, California.

We are presenting the business descriptions of the parent company OXIS International, Inc., followed by that of our partial subsidiary, BioCheck, Inc., in separate sections because currently we own a 51% share of BioCheck.

Oxidative stress is associated with an excess of free radicals, reactive oxygen species and a decrease in antioxidant levels resulting in the development of tissue or organ damage. Oxidative stress can cause tissue injury by triggering cell death or inciting a tissue-damaging inflammatory response. We have invested significant resources to build a substantial patent position on both our antioxidant therapeutic technologies and selected oxidative stress assays.

In 1965, the corporate predecessor of OXIS, Diagnostic Data, Inc. was incorporated in the State of California. Diagnostic Data changed its incorporation to the State of Delaware in 1972; and changed its name to DDI Pharmaceuticals, Inc. in 1985. In 1994, DDI Pharmaceuticals merged with International BioClinical, Inc. and Bioxytech S.A. and changed its name to OXIS International, Inc. Our principal executive offices were relocated to 323 Vintage Park Drive, Suite B, Foster City, California 94404 on February 15, 2006. Our phone number is (650) 212-2568.

Our lead therapeutic antioxidant drug candidate, BXT-51072, completed a Phase IIA clinical trial in inflammatory bowel disease in 1999, but due to the lack of financial resources, we ceased further testing of BXT-51072. In September 2004, we entered into an Exclusive Licensing Agreement relating to BXT-51072 and related compounds with HaptoGuard, Inc., which has since been merged into Alteon Inc. Under the agreement, we granted HaptoGuard exclusive worldwide rights, in certain defined areas of cardiovascular indications, to develop, manufacture and market BXT-51072 and related compounds from our library of such antioxidant compounds. Under the license agreement, HaptoGuard is responsible for worldwide product development programs with respect to the licensed compounds.

We intend to pursue development of our MPO, a research assay, for sale either alone or in combination with other assays into the clinical diagnostic market. We are also pursuing development of Ergothioneine for marketing as a nutraceutical supplement.

As discussed above, our therapeutic and nutraceutical product portfolio includes three classes of small molecular weight antioxidant molecules: glutathione peroxidase mimics including BXT-51072, Ergothioneine analogs and lipid soluble antioxidants. We intend to focus on and intensify our efforts to consummate diagnostic, pharmaceutical and nutraceutical relationships and strategic partnerships with larger companies for the purpose of further developing and exploiting our antioxidant molecules. No assurance can be given that our efforts will generate the results anticipated by our management or will in the future be favorable to us.

Marketed Products

We have developed, commercialized and marketed an extensive product line that provides several types of tools for researchers to identify and measure the balance between oxidative, nitrosative, antioxidant and inflammatory biomarkers in biological samples. We offer more than 60 research products for sale, including 25 research diagnostic assay test kits for markers of oxidative and nitrosative stress. We also market antibodies, enzymes and controls for use primarily in research laboratories. The antibodies provide detection of oxidative, nitrosative, antioxidant and inflammatory markers different from those measured by assay test kits. The enzymes have been shown in early in vitro studies and preclinical animal studies to allow manipulation and control of oxidative biomarkers of protein and DNA, nitric oxide, antioxidant enzymes and inflammatory neutrophils. Controls have been shown in controlled in vitro studies and in vivo preclinical studies to allow regulation and monitoring of oxidative biomarkers of lipids, proteins and DNA, and nitrosative and antioxidant biomarkers. In addition, we have marketed the antioxidant Ergothioneine to selected customers in the cosmetics industry.

Research Diagnostic Assays

Our primary research diagnostic assay product line is comprised of approximately 30 assay test kits which measure key markers in free radical biochemistry for oxidative and nitrosative stress. Specifically, these assays measure levels of general and specific antioxidant activity, oxidative alterations to organic lipid, protein and DNA substrates, and pro-oxidant activation of specific white blood cells. Fifteen of our research assays were manufactured at our facility in Portland, Oregon and with the closing of the Portland facility, the manufacturing of our research assays was transferred to BioCheck’s Foster City facility during the first quarter of 2006. As of the date of this prospectus, BioCheck is manufacturing our research assays under a mutual services agreement with us. If BioCheck ceased manufacturing our research assays before we engaged an alternative manufacturer, our business would be adversely affected. Ten other research assays are manufactured by third party suppliers pursuant to private label arrangements.
 
27
 
Our research diagnostic assay test kits utilize either chemical (colorimetric) or immunoenzymatic reactions that can be read using laboratory spectrophotometers and microplate readers, respectively. We believe our assays offer advantages over conventional laboratory methods, including ease of use, speed, specificity and accuracy. Our research diagnostic assays for markers of oxidative stress are generally protected by trade secrets, and to some extent, patents. Five U.S. patents and eight international patents have been issued with respect to these assays. The oxidative stress assays are sold under the registered trademark “BioxytechÒ.” We continue to offer a few proprietary antioxidants and specialty chemicals but our product development focus and support are directed at assays, antibodies and enzymes in the area of oxidative and nitrosative stress. 

Revenues from sales of our research diagnostic assays and Ergothioneine comprised 95% and 81% of total revenues in 2005 and 2004, respectively.

Ergothioneine

Ergothioneine is a naturally occurring, water soluble, antioxidant amino acid molecule found in most animals and plants. It is considered one of the most powerful antioxidants available. Ergothioneine neutralizes hydroxyl free radicals and selectively increases the activity of the special antioxidant enzymes. It increases respiration and oxidation of fat, protects the mitochondria from damage due to environmental ultraviolet radiation and aids in the detoxification of the liver. We have developed a proprietary method for producing synthetically derived L-Ergothioneine in commercial quantities. We hold the patents and patent applications for the protective effect of Ergothioneine on mitochondria, the commercial preparation process and the neuroprotectant methods and compositions of Ergothioneine.

We sell Ergothioneine to selected customers as an anti-aging product in skin care products sold in the cosmetics industry. Sales of Ergothioneine were $18,000 in 2005 and $87,000 in 2004. Sales during 2005 and 2004 were to one customer in the cosmetics industry in connection with such customer’s marketing campaign of a formulation of cosmetics which included, among other things, Ergothioneine. We have not received any indication that additional orders are expected. We can give no assurances that sales of Ergothioneine to this customer or other cosmetics industry customers will resume.

Raw Material Suppliers

During 2005 we purchased raw materials from several suppliers, of whom the top three comprised 34%, 13% and 12% of our raw materials costs. We believe we could readily find alternative suppliers, or that we could readily market alternative products with adequate raw material supply, if necessary. Accordingly, we believe there is limited risk of over reliance on any supplier.

Marketing

We market products and technologies related to oxidative stress. Oxidative stress occurs as a result of an imbalance between damaging free-radicals and related molecules and their inactivation by antioxidants. Oxidative stress can cause tissue injury by triggering cell death or inciting a tissue-damaging inflammatory response.

During 2005, we continued to market our research diagnostic assay products to professional scientists in academia, industry and government through our OXISResearch catalog. Our marketing program is centered on targeting medical, environmental and various industry audiences interested in oxidative and nitrosative stress. Nitrosative stress occurs when the generation of reactive nitrogen species in a system exceeds the system’s ability to neutralize and eliminate them. Primary vehicles for this marketing program include printed literature, the OXISResearch website and attendance at conferences targeting neuroscience, cancer, cardiac and nutritional researchers.

Our assays for markers of oxidative stress are currently being sold both directly by us and through a network of distributors to researchers primarily in the United States, Europe and the Pacific Rim. We estimate that there are more than 10,000 scientists and clinicians who are working directly in research on free radical biochemistry, and who are potential customers for these research diagnostic assays. We continue to seek to strengthen our international distribution network by adding new distributors around the world. These distributors are primarily focused on sales of research products in the life science market. In 2005, 20 distributors accounted for approximately 53% of our total revenues. Although we have not recruited distributors for Ergothioneine, we intend to establish and implement a plan to do so in the future.

During 2005, approximately 15% of our total revenues were from EMD Biosciences, Inc., a distributor customer located in the United States. We expect revenues from sales to EMD Biosciences, Inc. for fiscal year 2006 to be similar to those in 2005.

Ergothioneine as a Nutraceutical Supplement

We believe that our Ergothioneine compound may be well suited for development as a nutraceutical supplement that can be sold over the counter and we intend to pursue the development of Ergothioneine for use in such markets. We have outsourced the manufacturing of the raw material and we are working to expand this manufacturing capacity. We are currently testing Ergothioneine produced in bulk to ensure that its purity level is acceptable.

Myeloperoxidase Assay/Cardiovascular Predictor Product

Given sufficient capital resources, we intend to pursue development of our myeloperoxidase assay, or MPO, a research assay, which could be utilized either alone or in combination with other assays in the clinical diagnostic market. Currently, biomarkers used for myocardial infarction present significant limitations in predictive quality due to variability of patient population, the range for abnormal test results and other factors. In contrast, blood plasma MPO levels, as measured by our MPO kit using our proprietary monoclonal antibody, appear to be a better predictor of patients at risk for cardiac events before they occur, according to a report in the October 23, 2003 New England Journal of Medicine. Our MPO assay kit was used in that study to evaluate myeloperoxidase levels in 604 hospital emergency room patients with chest pain. A single measurement of plasma myeloperoxidase using our MPO assay kit was able to identify patients at early risk for a heart attack, even when no tissue damage to the heart was evident. Furthermore, the test independently predicted the risk of a major cardiac event following the initial visit to the emergency room.

We have undertaken collaborative research with selected research scientists on the development of a cardiovascular predictor product using our MPO assay combined with other assays currently in-house or under development. We are reassessing this development program in the context of our partial acquisition of BioCheck.

Out-Licensed Technology

Our lead therapeutic drug candidate, BXT-51072, is a low molecular weight oral drug that mimics the antioxidant enzyme glutathione peroxidase. It directly neutralizes hydrogen peroxide and appears to protect cells from peroxide mediated damage. It also inhibits nucleic transcription and prevents the activation of cytokines, adhesion molecules and inflammatory enzymes, which are all mediators of inflammation. We completed a Phase IIA clinical trial in inflammatory bowel disease with BXT-51072 in 1999. This Phase IIA trial was a multi-center, nonrandomized, open-label, two-arm study which assessed the safety, pharmacokinetics, and efficacy of BXT-51072. Due to the lack of financial resources, we ceased further testing of BXT-51072.

In September 2004, we entered into an Exclusive License and Supply Agreement relating to BXT-51072 and related compounds with HaptoGuard, Inc., a New York based biopharmaceutical company which has since been merged into Alteon Inc. Under the agreement, we granted HaptoGuard exclusive worldwide rights, in certain defined areas of cardiovascular indications, to develop, manufacture and market BXT-51072 and related compounds from our library of such antioxidant compounds. Under the license agreement, HaptoGuard is responsible for worldwide product development programs with respect to the licensed compounds. We received an upfront license fee of $450,000, and HaptoGuard is obligated to pay royalties on net sales of certain licensed products, as well as additional fees for the achievement of development milestones in excess of $21 million if all milestones are met and regulatory approvals are granted. There can be no assurances that royalty payments will result or that milestone payments will be realized.

We have the right to terminate the license agreement if HaptoGuard fails to pay us any required payments under the license agreement or if HaptoGuard fails to comply with certain development plan and timeline requirements relating to the development of the licensed compounds. In December 2005, HaptoGuard elected to take a one-time six month extension of their obligation to begin Phase II clinical studies of a licensed product in cardiovascular disease pursuant to the development plan timeline. As provided in the license agreement, HaptoGuard paid a fee of $100,000 for the extension.
 
30
 
On July 20, 2006, we entered into an amendment to the exclusive license and supply agreement originally signed on September 28, 2004 with HaptoGuard. We granted HaptoGuard three-month extensions to fulfill its obligation to begin Phase II clinical trials with a licensed product. HaptoGuard may obtain three such extensions upon payment of $50,000 for each extension. In addition, we agreed to change the timeline for initiation of Phase IIb clinical trials with a licensed product under the license agreement and agreed to allow the same extension arrangement for that milestone. We received a $50,000 payment from HaptoGuard on July 24, 2006 for the first extension ending on September 30, 2006.

HaptoGuard may terminate the agreement by providing us with 180 days’ written notice. Either party may terminate the agreement upon 30 days’ written notice upon certain events relating to the other party’s bankruptcy, insolvency, dissolution, winding up or assignment for the benefit of creditors, or upon the other party’s uncured breach of any material provision of the agreement. Otherwise, the license agreement terminates upon the expiration of the underlying patents relating to the licensed compounds.

These patents can expire earlier if they are abandoned or are not adequately maintained. We cannot assure you that corresponding patents will be issued or that the scope of the coverage claimed in our patent applications will not be significantly reduced prior to any patent being issued.

Competition
 
The diagnostic, pharmaceutical and nutraceutical industries are highly competitive. Competition in most of our primary current and potential market areas is intense and expected to increase. There can be no assurance that we can compete successfully.
 
Presently the main commercial competition in our research assay business is represented by, but not limited to Cayman Chemical Company, Assay Designs and Randox Laboratories, Ltd. In addition, our competitors and potential competitors include large pharmaceutical and nutraceutical companies, universities and research institutions. These competitors may have substantially greater capital resources, research and development staffs, facilities and manufacturing expertise than us. In addition, our competitors may develop new technologies or use existing technologies that may be the basis for competitive products.

Employees

As of December 31, 2005, we had 11 full time employees. On December 1, 2006, we had five full time employees, including one scientist in manufacturing/research and development, one employee in marketing and three employees in administrative and operational support. On December 6, 2005, we initiated a relocation plan to cease our operations in Portland, Oregon and relocate to Foster City, California at premises adjacent to those of BioCheck. We decided to relocate after reviewing and evaluating all aspects of our operations to determine the profitability and viability of continuing in the Portland, Oregon location. As part of the relocation that was effective February 15, 2006, we offered all regular full-time employees who were not relocated to Foster City, California severance benefits under an employee incentive package estimated to cost approximately $119,000.

None of our employees are subject to a collective bargaining agreement. We believe our relationship with our employees is good, and we have never experienced an employee-related work stoppage.


BIOCHECK, INC.

On September 19, 2005, we entered into a stock purchase agreement with BioCheck and its stockholders to purchase all of its common stock for $6.0 million in cash. BioCheck is a leading producer of enzyme immunoassay diagnostic kits for clinical laboratories. On December 6, 2005, we purchased 51% of the shares of BioCheck’s common stock from each of its stockholders on a pro rata basis for $3,060,000 in cash. Pursuant to the stock purchase agreement, we will use our reasonable best efforts to consummate a follow-on financing transaction to raise additional capital with which to purchase the remaining outstanding shares of BioCheck in one or more additional closings.

We are presenting the business summaries of the OXIS parent company and BioCheck separately because we do not currently own 100% of BioCheck. If we successfully acquire the remaining 49% equity interest in BioCheck by OXIS, the combined company plans to leverage its expertise to focus on the growing clinical diagnostic biomarker market and to develop diagnostic assays designed to help physicians provide more timely and accurate diagnoses and treatment plans for their patients.

BioCheck is a leading producer of clinical diagnostic assays, including high quality enzyme immunoassay research services and products offering immunoassay kits designed to improve the accuracy, efficiency, and cost-effectiveness of in vitro (outside the body) diagnostic testing in clinical laboratories. BioCheck’s mission is to develop unique, proprietary immunoassays designed to help physicians provide more timely and accurate diagnoses, prognoses and treatment plans for their patients.

The clinical diagnostics market consists of companies that develop and manufacture a wide array of instruments, immunoassays reagents and data analysis tools. Diagnostic instruments are the key hardware components, such as automated immunoassay analyzers, used in the automatic processing of the diagnostic tests. Reagents are the bioactive test ingredients which, when combined with the biologically derived samples, provide the diagnostic test results. The analysis tools, such as software programs and applications, assist the researchers and clinicians in the interpretation of data collected from high-volume analyzers and reagents.

BioCheck focuses primarily on the immunoassay segment of the clinical diagnostics market. The simplified, basic components of any immunoassay system are: an antigen, an antibody specific to this antigen, and a system to measure the amount of the antigen in a given sample. The commonly used immunoassays share four common components required to produce a high quality immunoassay product: a supply of high-purity antigens, a supply of high quality, specific monoclonal or polyclonal antibodies, a stable detection system, and a precise method for separating the bound detection system at the end of the reaction. The ability to develop, isolate and maintain the antibodies is a critical component of immunoassay technology.
 
The senior management of BioCheck has several decades of combined research and development, clinical and operational experience in the biotechnology and pharmaceutical industries. BioCheck’s management has a core competency and a proven scientific and business development track record in developing and manufacturing high-quality immunoassay products.

Customers of BioCheck consist of small and medium-sized laboratories, and larger volume clinical diagnostics laboratories that outsource or license their reagent assembly to BioCheck under research services agreements. BioCheck’s products are also sold through its global distribution network of third-party distributors and re-sellers.

BioCheck’s clinical immunoassays are applicable to the diagnosis and management of infectious diseases; detection of certain types of cancer, and cardiac, reproductive, and thyroid disorders; and the measurement of the effects of therapeutic drug administration. The testing process is performed in vitro in samples of blood, urine, and other bodily fluids.

Products and Services

Clinical Diagnostics Immunoassay Kits

BioCheck offers its clinical laboratory and in vitro diagnostics customers over 40 clinical diagnostic assays manufactured in its 15,000 square-foot, U.S. Food and Drug Administration, or FDA, certified Good Manufacturing Practices device-manufacturing facility in Foster City, California. Of the 40 total clinical diagnostic assays offered by BioCheck, 17 clinical diagnostic assays have been cleared by the FDA for marketing and sales and a number of its products have FDA certificates to foreign governments and certificates of exportability. BioCheck’s clinical diagnostic kits have been registered in Brazil, China, India, Italy, Taiwan, Turkey, and the United Kingdom, and BioCheck’s distributors deliver its products to countries in Central and South America, Europe, the Middle East, and Asia.
 
34
 
BioCheck’s primary product line consists of enzyme linked immunoassay, or ELISA, kits that are widely used in medical laboratory settings. An ELISA test consists of linking an antibody or antigen to an enzyme in order to detect a match between the antibody and antigen. An ELISA test is used to detect specific antigens in a biological sample and the presence of antibodies attached to specific antigenic sites on proteins or other molecules in a biological sample.

The primary antibody development platform of BioCheck utilizes hybridoma technology. This process creates monoclonal antibodies to precisely measure very low concentrations of proteins in blood and plasma. The ability to express, isolate and maintain high-quality antibodies is a critical component of immunoassay test kit technology. BioCheck uses standard chromatography technology and its proprietary antibody conjugation methods for its antibody purification services and antibody conjugates. We believe that BioCheck’s products and services exceed industry average standards for stability and purity.

Test kits manufactured by BioCheck identify the existence, and in some cases the amount, of a specific molecule, or marker, that is an indicator of a condition or disease state. These test kits are applicable to cardiac markers; tumor markers for liver, ovarian, breast, prostate and gastrointestinal conditions; infectious diseases including pregnancy-related panel screens for toxoplasmosis, rubella, cytomegalovirus, and the herpes virus; thyroid function; steroids including Estradiol, Progesterone, Testosterone, and Estriol; and fertility hormones. 

BioCheck’s revenues from product shipments were $2.7 million in the nine months ended September 30, 2006, $3.5 million in 2005, $3.9 million in 2004, and $3.3 million in 2003.

Research Services

In addition to clinical and research assay products, BioCheck provides various research services to pharmaceutical and diagnostic companies worldwide. Research services consist primarily of highly specialized laboratory testing that enhances the speed, and lowers the clinical risk, of the pharmaceutical development process. The services include custom immunoassay development, antibody purification and conjugation, and immunoassay assembly.

Cardiovascular Markers

Coronary heart disease, or CHD, is the most common form of heart disease caused by a narrowing of the coronary arteries that feed the heart. It is the number one cause of mortality for both men and women in the U.S. Approximately seven million Americans suffer from CHD and more than 500,000 Americans die of heart attacks caused by CHD every year.

The National Heart, Lung, and Blood Institute sponsored a multi-center epidemiologic study in 2003. Increased levels of lipoprotein-associated phospholipase, or Lp-PLA2, in patients followed in this study have been linked to increased risk of CHD. In collaboration with diaDexus, BioCheck has developed and manufactures an FDA cleared clinical diagnostic test for Lp-PLA2 called the PLAC test. While the PLAC test is not a stand-alone test for predicting CHD, it provides supportive evidence when used with clinical evaluation and other tools for patient risk assessment. An elevated PLAC level with an LDL-cholesterol level of less than 130 mg/dL suggests that patients have two to three times the risk of having coronary heart disease when compared with patients having lower PLAC test results. BioCheck manufactures the PLAC test and diaDexus promotes and sells it to the medical community.

BioCheck’s revenues from PLAC test manufacturing and services were approximately $350,000 in the nine months ended September 30, 2006, $340,000 in 2005, $580,000 in 2004, and $470,000 in 2003.

Patents and Trademarks

As of December 31, 2005, BioCheck had filed two patent applications covering research and diagnostic assays to detect molecules and proteins related to tumor angiogenesis and certain cardiac conditions. Angiogenesis is the formation of blood vessels in tumors.

In April 2004, AngioGenex, Inc., or AngioGenex, based in New York City, and BioCheck entered into an agreement to develop cancer diagnostic and prognostic products based on the Id-gene platform technology licensed exclusively to AngioGenex by the Albert Einstein College of Medicine and the Memorial Sloan Kettering Cancer Center. The agreement assigns to BioCheck exclusive rights to develop and market diagnostics based on AngioGenex’s Id technology in return for royalties.

A critical component of the clinical validation of an Id-protein based diagnostic/prognostic product is the development of monoclonal antibodies, or mAbs, to the Id proteins. Id proteins play a significant role in the process of tumor related angiogenesis and other functions related to blood vessel formation. BioCheck has developed rabbit monoclonal anti-Id1, Id2 and Id3 antibodies for Western Blot analyses and immunohistochemistry staining, and ELISA tests for measuring Id1, Id2 and Id3 in cell culture supernatants, and cell and tissue extracts.

AngioGenex and BioCheck have filed joint patent applications for the mAbs to the Id-proteins. Under the joint patent application, BioCheck has the exclusive rights to the diagnostic applications of the Id proteins while AngioGenex owns the rights for the therapeutic drug applications. U.S. Provisional Application Serial No. 60/691,060 was filed on June 16, 2005 related to the Id1 protein, titled “Novel Rabbit Monoclonal Antibodies to Id1”. The patent application related to the Id3 protein, titled “Rabbit Monoclonal Antibody Against Human Id3 Protein” was filed on January 27, 2006.

BioCheck has filed a patent application for a clinical diagnostic related to the troponin protein complex. Certain types of troponin including cardiac troponin I and T are highly sensitive and specific indicators of damage to the heart muscle. Myocardial infarction, or a heart attack, can be differentiated from unstable angina, or pain, by measuring troponin in the blood in patients with chest pain. Patent application serial number 11/116,290 was filed April 28, 2005 titled “Immunoassay for Cardiac Troponin-I in Non-Human Mammalian Species.” John Chen is a co-inventor of the invention that is the subject of this patent application.

Sales and Marketing

BioCheck develops, manufactures and markets high quality immunoassay products and technologies designed to improve the accuracy, efficiency, and cost-effectiveness of in vitro diagnostic testing in clinical laboratories. The company also provides research services to pharmaceutical and diagnostic companies worldwide. These services consist primarily of highly specialized laboratory testing that enhances the speed and lowers the clinical risk of the pharmaceutical development process.

During 2005, BioCheck marketed its products and research services to professional clinicians and researchers primarily through the company’s product catalog, printed materials, website and attendance at key industry tradeshows and conferences. A portion of BioCheck’s 2005 sales volume was also generated through referrals from existing customers. BioCheck’s products are sold directly to customers and through a network of international distributors, who deliver its products to purchasers in North, Central and South America, Europe, the Middle East, and Asia. BioCheck does not plan to establish an in-house sales force to distribute its products.
 
37
 
In 2005, the top twenty direct customers accounted for approximately 67% of BioCheck’s gross sales revenue and no single customer accounted for more than 15% of total gross sales revenue. BioCheck is seeking to identify and secure additional opportunities for research services agreements.

Competition

According to Boston Biomedical Consultants and Morgan Stanley Research Estimates, the worldwide clinical diagnostics market including instruments, immunoassays, rapid diagnostic tests and data analysis tools was approximately $22 billion in sales revenue in 2004 and increased approximately 9% from the previous year. Competition in the clinical diagnostics market is intense and highly fragmented, with the largest competitor, Roche Diagnostics, holding a 16% market share.

BioCheck’s direct competitors are developers and manufacturers of research and clinical diagnostic products and include, but are not limited to, Adaltis Inc., BioSource International, Inc., Diagnostic Products Corporation, Monobind, Inc. and BioClone Australia Pty Ltd.

In order to continue to successfully market BioCheck’s products and services, the company will be required to demonstrate that its immunoassay products meet or exceed the industry standards for quality as measured by high levels of purity, stability, precision of measurement and cost effectiveness. The company’s competitors may succeed in developing or marketing products that are more effective or commercially attractive. The launch of these competitive products may adversely impact the market pricing for BioCheck’s products as some of these competitors have substantially greater financial, technical, research and development resources and more established marketing, sales, distribution and service organizations. 

Raw Material Suppliers

The development and production of BioCheck’s products requires the company to purchase bulk quantities of antibodies, enzymes, microtiter plates and serum from outside vendors. BioCheck does not rely on any single supplier for its raw material purchases.

Research and Development

BioCheck invested $432,000, $726,000 and $839,000 in research and development in the nine months ended September 30, 2006, and the years 2005 and 2004, respectively. As of December 31, 2005, BioCheck employed seven employees in research and development. During 2005, BioCheck’s research staff was primarily used to produce compounds for diagnostic use and optimize methods for binding these compounds to biological reagents such as antibodies. BioCheck employs a proprietary process for antibody conjugation resulting in highly stable products. BioCheck also developed proprietary clinical diagnostics tests that include promising new angiogenesis tumor markers and an aggressive breast cancer marker, which were launched in the fourth quarter of 2006.

Angiogenesis Tumor Markers

In April 2004, BioCheck entered into a development and marketing agreement with AngioGenex for the diagnostic/prognostic applications of Id proteins in angiogenesis, which is the formation of blood vessels. The therapeutic and diagnostic applications of this process were patented by Memorial Sloan-Kettering Cancer Center and Albert Einstein Medical College and licensed to AngioGenex. The diagnostic application was subsequently licensed to BioCheck.

Id genes are expressed at high levels to produce Id proteins in many tissues during human embryonic development, but are generally not expressed, or expressed at very low levels, in adults except in some tumor cell types and tumor blood vessels. Id1, Id2 and Id3 proteins have been closely implicated in tumor-associated angiogenesis. Interfering with the action of the Id proteins may prove to be very effective in preventing the growth and metastases of both early and established tumors. The effectiveness of this approach has been demonstrated in commercially available therapeutic drugs, such as Avastin™, which targets the vascular endothelial growth factor. Such therapeutics have been modestly effective, suggesting the need for research and development to identify more powerful and specific agents for cancer therapy.

BioCheck’s goal is to clinically validate an Id-based diagnostic/prognostic product in collaboration with AngioGenex. During 2005, BioCheck’s research staff continued to work on the clinical validation of potential diagnostic products based on Id proteins related to tumor angiogenesis. Monoclonal antibodies to the Id proteins are required in order to develop highly sensitive ELISA diagnostic and prognostic tests. BioCheck has developed rabbit monoclonal anti-Id1, Id2 and Id3 antibodies that can be used in cell and tissue extracts through commonly utilized detection methods including Western Blot analysis, immunohistochemistry staining and ELISA tests. Western Blot analysis is a method of separating proteins by mass through a gel based process. Immunohistochemistry staining is a process of localizing proteins in cells by tagging their respective antibodies with color producing tags. ELISA tests are used for measuring the amount of Id1, Id2 and Id3 proteins in cell culture supernatants, and cell and tissue extracts.

Aggressive Breast Cancer Marker

In 2005, BioCheck entered into a development and marketing agreement with HMGene, Inc., or HMGene, based in Piscataway, New Jersey for the development and manufacturing of an ELISA test for the HMGA2 gene. The HMGA2 gene has been implicated in aggressive forms of breast cancer. The detection technology for tissue staining and peripheral blood samples related to the HMGA2 gene has been patented by HMGene and licensed to BioCheck for the development of rabbit polyclonal and monoclonal anti-HMGA2 antibodies. These antibodies can be used for Western Blot analyses, immunohistochemistry staining and ELISA assays.

While we believe that these are potentially promising diagnostic products, no assurances can be given that the company will have sufficient funding and resources to continue research, development and commercialization of these technologies.

Employees

As of December 1, 2006, BioCheck employed 25 full-time employees, including 13 technicians in manufacturing, seven scientists and research associates in research and development, two specialists in quality control functions, and three professionals in administrative and operational support.

Facilities

On December 6, 2005 we purchased 51% of BioCheck and initiated a transition plan to consolidate all operations at BioCheck’s manufacturing facility. Consequently, during 2006, we entered into a three-year lease agreement commencing on April 1, 2006 for 4,136 square feet of space immediately adjacent to BioCheck at 323 Vintage Park Drive, Suite B, Foster City, CA 94404. These premises serve to accommodate the relocation and consolidation of our corporate headquarters and operations.

BioCheck occupies approximately 15,000 square feet of administrative, laboratory and manufacturing space located at Vintage Park, 323 Vintage Park Drive, Foster City, CA 94404, pursuant to a lease expiring in December 2008. The facility has been certified according to the U.S. Food and Drug Administration, or FDA, Good Manufacturing Practice standards, which are subject to annual audits by the FDA. In addition, the facility has been certified to meet the highest international manufacturing standard (ISO 13485) generally accepted in Europe and Asia, according to the International Organization for Standardization, or ISO. BioCheck believes that it is in compliance with all other regulatory certifications applicable to its line of business, including Device Manufacturing License for the state of California, Registration of Device Establishment, Certificate of Foreign Government and Certificate of Exportability.

LEGAL PROCEEDINGS

A member of our board of directors, Steven T. Guillen, who was terminated from his position as our President and Chief Executive Officer on September 15, 2006, filed a lawsuit against us and up to 25 unnamed additional defendants. To the date of this prospectus, the complaint has not been served upon us or any other defendant. The complaint alleges breaches of contract relating to Mr. Guillen’s employment agreement and a promissory note that is in default, breach of implied covenant of good faith and fair dealing, wrongful termination and violation of the California Labor Code in relation to the non-payment of back pay. On March 10, 2006, we received $200,000 in exchange for an unsecured promissory note with Mr. Guillen. Interest and principal were due on September 10, 2006 and at September 30, 2006 were in default. On November 2, 2006, we repaid Mr. Guillen the principal and accrued interest due on the promissory note in the amount of $209,000 and back pay with penalties and accrued interest of $96,000. We are in ongoing negotiations with Mr. Guillen’s counsel to settle the lawsuit.

Other than Mr. Guillen, no other director, officer or affiliate of ours, and no owner of record or beneficial owner of more than five percent (5%) of the securities of the Company, or any associate of any such director, officer or security holder is a party adverse to us or any of our subsidiaries or has a material interest adverse to us or any of our subsidiaries in reference to pending litigation.

MANAGEMENT’S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

The following discussion and analysis or plan of operation should be read in conjunction with the financial statements and related notes. This discussion contains forward-looking statements based upon our current expectations and involves risks and uncertainties. Our actual results and the timing of certain events could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including those set forth in “Risks Related to Our Business,” “Business” and elsewhere in this document. See the paragraphs following the heading “Forward-Looking Statements” for additional discussion.

Management’s Discussion and Analysis or Plan of Operation is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States.

Introduction

We incurred net losses of $3.1 million in 2005 and $2.7 million in 2004. BioCheck generated a net profit of $0.2 million in 2005. This amount of profit would not be enough to offset our current losses. Our 2005 net loss includes an expense of $1.5 million for purchased in-process research and development that is not anticipated to reoccur in 2006. We incurred net losses of $1.9 million in the nine months ended September 30, 2006. Our plan is to increase revenues to generate sufficient gross profit in excess of selling, general and administrative, and research and development expenses in order to achieve profitability. However, we can not assure you that we will accomplish this task and there are many factors that may prevent us from reaching our goal of profitability.

On a consolidated basis, we had cash and cash equivalents of $614,000 at December 31, 2005 of which $282,000 was held by BioCheck. The cash held by us of $332,000 at December 31, 2005 was not sufficient to sustain our operations through the first quarter of 2006 without additional financings. During March 2006, we received $200,000 from Steven T. Guillen, our President and Chief Executive Officer in exchange for a promissory note and we entered into a Promissory Note, or Note, with Fagan Capital, Inc., pursuant to which Fagan Capital loaned us $400,000.
 
On a consolidated basis, we had cash and cash equivalents of $677,000 at September 30, 2006, of which $656,000 was held by BioCheck. Since BioCheck has been and is expected to continue to be cash flow positive, management believes that BioCheck’s cash will be sufficient to sustain BioCheck’s operating activities.

We had cash and cash equivalents of $21,000 at our parent level at September 30, 2006. We cannot access the cash held by our majority-held subsidiary, BioCheck, to pay for our parent level operating expenses. We incurred negative operating cash flows of $0.5 million during the nine months ended September 30, 2006 and $2.1 million during 2005, at our parent level. We incurred negative operating cash flows of $0.9 million during the nine months ended September 30, 2006 at our parent level. The current rate of cash usage at our parent level raises substantial doubt about our ability to continue as a going concern, absent any new sources of significant cash flows. In an effort to mitigate this near-term concern, we obtained debt financing in which we received proceeds of $1,350,000 subsequent to September 30, 2006 and we are seeking additional equity financing to obtain sufficient funds to sustain operations and purchase the remaining 49% of BioCheck for approximately $3.0 million. From this debt financing, $635,000 was used to repay existing debt, accrued interest and related legal fees. We plan to increase revenues by introducing new products. However, we cannot provide assurance that we will successfully obtain equity financing, if any, sufficient to finance our goals or that we will increase product related revenues. Our financial statements do not include any adjustments relating to the recoverability and classification of recorded assets, or the amounts and classification of liabilities that might be necessary in the event that we cannot continue in existence.

Overview

OXIS International, Inc. develops technologies and products to research, diagnose, treat and prevent diseases of oxidative stress associated with damage from free radical and reactive oxygen species. We derive our revenues primarily from sales of research diagnostic assays to research laboratories. Our diagnostic products include approximately 30 research assays to measure markers of oxidative stress. We hold the rights to three therapeutic classes of compounds in the area of oxidative stress, and have focused our commercialization programs in clinical cardiovascular markers, including MPO (myeloperoxidase) and GPx (glutathione peroxidase), as well as a potent antioxidant, Ergothioneine, that may be appropriate for sale over-the-counter as a dietary supplement. OXIS has acquired a 51% interest in and has the option to purchase the remaining 49% of BioCheck, Inc., or BioCheck.

Our majority-held subsidiary, BioCheck, Inc. is a leading producer of clinical diagnostic assays, including high quality enzyme immunoassay research services and immunoassay kits for cardiac and tumor markers, infectious diseases, thyroid function, steroids, and fertility hormones designed to improve the accuracy, efficiency, and cost-effectiveness of in vitro (outside the body) diagnostic testing in clinical laboratories. BioCheck focuses primarily on the immunoassay segment of the clinical diagnostics market. BioCheck offers over 40 clinical diagnostic assays manufactured in its 15,000 square-foot, U.S. Food and Drug Administration, or FDA, certified Good Manufacturing Practices device-manufacturing facility in Foster City, California.

Current significant financial and operating events and strategies are summarized as follows:

Relocation of Operations

On December 6, 2005, we initiated a relocation plan to cease our operations in Portland, Oregon and relocate to Foster City, California. We decided to relocate after reviewing and evaluating all aspects of our operations to determine the profitability and viability of continuing in the Portland, Oregon location. During February 2006, we signed a lease agreement for approximately 4,000 square feet of space located immediately adjacent to those of BioCheck and relocated our manufacturing operations to Foster City, California. On February 15, 2006, we ceased operations at the Portland, Oregon facility and most of the Portland, Oregon employees were terminated. In connection with the relocation, we accrued $119,000 during 2005 for employee severances offered to all regular full-time employees who were not relocated to Foster City, California. Of this amount, $103,000 has been paid during the first nine months of 2006, resulting in $16,000 of accrued expenses at September 30, 2006. We expect $8,000 of this amount to be paid during the remainder of 2006 and $8,000 is to be paid during 2007.

Product Development

During the nine months ended September 30, 2006, we expanded our product portfolio of research assay kits for the research markets with the addition of eight new assay products.  Given the availability of sufficient capital resources, we plan to pursue the development of cardiac markers.  We are planning to expand our cardiovascular and inflammatory products through the combination of our myeloperoxidase, or MPO, assay with other in-house assays and new assays in development.  We also believe that our Ergothioneine compound may be well suited for development as a nutraceutical supplement that can be sold over the counter.  We are currently testing Ergothioneine produced in bulk to ensure that its purity level is acceptable. Given the availability of sufficient capital resources and the successful scale-up to a bulk manufacturing process that ensures an acceptable level of purity, we intend to pursue the development of Ergothioneine for use in the over the counter market, however, there can be no assurance as to when or if we will launch Ergotheioneine on a commercial basis as a nutraceutical.  
 
42

BioCheck currently has several products under development for cancer, cardiac/inflammatory and angiogenesis research applications.  A research assay and reagents for the detection of HMGA2, a marker for aggressive breast cancer, are under development.  Myeloperoxidase is an inflammatory protein that has utility as a prognostic marker for cardiac events.  A new myeloperoxidase research assay has been developed that we expect will result in commercial sales in the fourth quarter of 2006.  Id proteins play a central role in cell differentiation, and Id1 and Id3 play a central and critical role in tumor related angiogenesis.  BioCheck has developed research assays and rabbit monoclonal antibodies for the detection of human and mouse Id proteins. We currently expect that the Id protein assays and reagents will be ready for commercial launch by late 2006.

Loans and Warrants

On December 6, 2005, we entered into a non-revolving one-year loan agreement with KeyBank, N.A., or KeyBank, and received funds of $3,060,000 to purchase 51% of BioCheck’s common stock. As security for our repayment obligations, we granted a security interest to KeyBank in our $3,060,000 certificate of deposit at KeyBank. This loan was repaid during February 2006 and a new one-year loan agreement for $3,060,000 was entered into with Bridge Bank. As part of the loan arrangement with Bridge Bank, we granted a security interest in a $3,060,000 certificate of deposit moved from KeyBank to Bridge Bank. The loan bears interest at 3.0% and the certificate of deposit bears interest at 1.0%.

On March 10, 2006, we received $200,000 in exchange for an unsecured promissory note with Steven T. Guillen, our president and chief executive officer at that time. The related party note bears interest at 7.0%. Interest and principal were due on September 10, 2006. Mr. Guillen’s employment was terminated on September 15, 2006. We were in default on this note at September 30, 2006. Subsequent to September 30, 2006, Mr. Guillen has sued the Company for payment of interest and principal due under the note. On November 2, 2006, the Company paid to Mr. Guillen amounts owing under the note.

On March 31, 2006, we issued a $400,000 unsecured promissory note to Fagan Capital, Inc., or Fagan Capital. Interest accrues at an annual rate of 8.0% and interest and principal were due on June 2, 2006. On July 26, 2006, Fagan Capital extended the maturity date of the promissory note to June 1, 2007 and we issued to Fagan Capital a warrant to purchase 1,158,857 shares of common stock at an initial exercise price of $0.35 per share. On October 25, 2006, the Company prepaid the principal, accrued interest and legal fees due pursuant to the Renewal Note in the amount of $426,000 and the Company undertook to finalize a registration rights agreement covering the shares underlying the common stock purchase warrant within 7 days of the prepayment of the Renewal Note. See Notes 3 and 7 to the unaudited consolidated financial statements for the nine months ended September 30, 2006, included in this prospectus. The purpose of these loans was to provide us with short term financing as we sought longer term financing.

Debt Financing

On October 25, 2006, we entered into a Securities Purchase Agreement, or Purchase Agreement, with four accredited investors, or the Purchasers. In conjunction with the signing of the Purchase Agreement, we issued Secured Convertible debentures, or debentures, and Series A, B, C, D, and E common stock warrants, and we also provided the investors with registration rights under a registration rights agreement, and a security interest in our assets under a security agreement to secure the performance of our obligations under the debentures.
 
43
 
Pursuant to the terms of the Purchase Agreement, we issued the debentures in an aggregate principal amount of $1,694,250 to the Purchasers. The debentures were issued with an original issue discount of 20.318%, and resulted in proceeds to us of $1,350,000. The debentures are convertible, at the option of the holders, at any time into shares of common stock at $0.35 per share, as adjusted in accordance with a full ratchet anti-dilution provision (referred to in this prospectus as the “conversion price”). Beginning on the first of the month following the earlier of the effective date of the registration statement to be filed pursuant to the registration rights agreement and February 1, 2007, we will amortize the debentures in equal installments on a monthly basis resulting in a complete repayment by the maturity date (the “Monthly Redemption Amounts”). The Monthly Redemption Amounts can be paid in cash or in shares, subject to certain restrictions. If we choose to make any Monthly Redemption Amount payment in shares of common stock, the price per share is the lesser of the conversion price then in effect and 85% of the weighted average price for the ten trading days prior to the due date of the Monthly Redemption Amount.
 
The performance of our duties and obligations under the debentures are secured by substantially all of our assets under a security agreement. As additional security to the debenture holders, we have also pledged the shares we hold in our subsidiaries, including 51% of BioCheck, Inc., and all of the shares of capital stock of our wholly-owned subsidiaries, OXIS Therapeutics, Inc. and OXIS Isle of Man Limited. In addition, OXIS Therapeutics, Inc. and OXIS Isle of Man Limited, have each entered into a subsidiary guarantee under which these subsidiaries have guaranteed the performance, at the parent level, of our obligations under the debentures.
 
Under the debentures, we agreed that we will not incur additional indebtedness for borrowed money, other than our current Bridge Bank Promissory Note. We also covenant that we will not pledge, grant or convey any new liens on its assets. The obligation to pay all unpaid principal will be accelerated upon an event of default, including upon failure to perform its obligations under the Debenture covenants, failure to make required payments, default on any of the Transaction Documents or any other material agreement, lease, document or instrument to which we are obligated, the bankruptcy of OXIS or related events. The Purchasers have a right of first refusal to participate in up to 100% of any future financing undertaken by us until the later of the date that the debentures are no longer outstanding and the one year anniversary of the effective date of the registration statement. We are restricted from issuing shares of common stock or instruments convertible into common stock for 90 days after the effective date of the registration statement with certain exceptions. We are also prohibited from effecting any subsequent financing involving a variable rate transaction until such time as no Purchaser holds any of the debentures. In addition, until such time as any Purchaser holds any of the securities issued in the Debenture transaction, if we issue or sell any common stock or instruments convertible into common stock which a Purchaser reasonably believes is on terms more favorable to such investors than the terms pursuant to the Transaction Documents, we are obligated to amend the terms of the Transaction Documents to such Purchaser the benefit of such better terms. We may prepay the entire outstanding principal amount of the debentures, plus accrued interest and other amounts payable, at our option at any time without penalty, provided that a registration statement is available for the resale of shares underlying the debentures and warrants, as more fully described in the debentures. The purpose of this Debenture transaction is to provide us with intermediate term financing as we seek longer term financing.
 
On October 25, 2006 in conjunction with the signing of the Purchase Agreement, we issued to the Purchasers five year Series A warrants to purchase an aggregate of 2,420,357 shares of common stock at an initial exercise price of $0.35 per share, one year Series B warrants to purchase 2,420,357 shares of common stock at an initial exercise price of $0.385 per share, and two year Series C warrants to purchase an aggregate of 4,840,714 shares of common stock at an initial exercise price of $0.35 per share. In addition, we issued to the Purchasers Series D and E warrants which become exercisable on a pro-rata basis only upon the exercise of the Series C warrants. The six year Series D warrants to purchase 2,420,357 shares of common stock have an initial exercise price of $0.35 per share. The six year Series E warrants to purchase 2,420,357 shares of common stock have an initial exercise price of $0.385 per share. The initial exercise prices for each warrant are adjustable pursuant to a full ratchet anti-dilution provision and upon the occurrence of a stock split or a related event.
 
44
 
Pursuant to the registration rights agreement, we must file a registration statement covering the public resale of the shares underlying the Series A, B, C, D and E warrants and the debentures within 45 days of the closing of the transaction and cause the registration to be declared effective within 120 days of the closing date. Cash liquidated damages equal to 2% of the face value of the debentures per month are payable to the purchasers for any failure to timely file or obtain an effective registration statement.
 
Under the security agreement, we agreed to grant to each of the investors a security interest in substantially all of our assets. We also agreed to pledge our respective ownership interests in our wholly-owned subsidiaries, OXIS Therapeutics, OXIS Isle of Man, and our partial subsidiary, BioCheck, Inc. OXIS Therapeutics and OXIS Isle of Man also provided a subsidiary guarantee to the Purchasers in connection with the transaction.
 
Stockholder Approval

On August 1, 2006, at the OXIS 2006 Annual Meeting of Stockholders, the five nominated directors were re-elected, the proposal to amend the Company’s Certificate of Incorporation to increase the number of authorized shares of common stock from 95,000,000 to 150,000,000 was approved, and the proposal to increase the number of shares reserved for issuance under the OXIS 2003 Stock Incentive Plan from 3,600,000 shares to 5,600,000 shares was also approved by the stockholders.

License Agreement Extension

On July 20, 2006, we entered into an amendment to the exclusive license and supply agreement originally signed on September 28, 2004 with HaptoGuard, Inc., which has since been merged into Alteon Inc. We granted HaptoGuard three-month extensions to fulfill its obligation to begin Phase II clinical trials with a licensed product. HaptoGuard may obtain three such extensions upon payment of $50,000 for each extension. In addition, we agreed to change the timeline for initiation of Phase IIb clinical trials with a licensed product under the license agreement and agreed to allow the same extension arrangement for that milestone. We received a $50,000 payment from HaptoGuard on July 24, 2006 for the first extension ending on September 30, 2006.

Agreements with Ambient Advisors LLC

On May 12, 2006, we entered into an engagement letter with Ambient Advisors LLC, or Ambient Advisors. Gary M. Post, a member of the board of directors, is the manager of Ambient Advisors. Ambient Advisors provided certain services pertaining to strategic planning, investor communications and financing strategies and other projects at the request of our chief executive officer for a one year period in return for monthly compensation of $5,000. We granted Ambient Advisors a ten year warrant to purchase 108,000 shares of OXIS common stock at an exercise price of $0.39 per share, with 9,000 shares becoming exercisable each month over the term of the agreement. On October 12, 2006, we mutually agreed with Gary M. Post to terminate the engagement letter with Ambient Advisors LLC, effective October 15, 2006, replace it with a new consulting agreement and accelerate the vesting of the warrant to be fully vested effective October 15, 2006.

On November 6, 2006, we entered into an advisory agreement with Ambient Advisors that commenced retroactively at October 15, 2006, or the Commencement Date. Ambient Advisors will provide certain services pertaining to strategic planning, financial planning and budgeting, investor relations, corporate finance and such additional roles and responsibilities as requested for a three year period from the Commencement Date, after this period on a year-to-year basis. Ambient Advisors will receive annual compensation in the amount of $83,333, payable quarterly in advance in cash, common stock based on a price equal to 85% of average of the five closing prices for the five trading days prior to the date that the issuance is authorized by the board of directors, or in ten year warrants equal to that number of warrants equal to 1.5 times the number of shares that would otherwise be received. For the initial quarterly payment, Ambient Advisors received a ten year warrant to purchase 173,608 shares of common stock with an exercise price of $0.20 per share, vesting immediately. As part of the compensation, we granted Ambient Advisors a ten year common stock purchase warrant to purchase 550,000 shares of OXIS common stock at an exercise price of $0.20 per share, vesting as follows: (i) 275,000 warrant shares vesting in four equal quarterly installments commencing on January 15, 2007 and every three months thereafter and (ii) and the remaining 275,000 warrant shares vesting in eight quarterly installments over two years. Additionally, OXIS granted Ambient Advisors, as a sign on bonus, a non-qualified option to purchase 333,333 shares at exercise price of $0.20 per share, with vesting in six equal installments, commencing on November 14, 2006, through the 180th day after the Commencement Date. During the three year term of the agreement, Ambient Advisors will receive an annual bonus based upon the attainment of agreed upon goals and milestones as determined by the board of directors and its compensation committee. During the remainder of calendar year 2006, Ambient Advisors’ bonus will be pro rated on an annual bonus rate in the range of 25% to 50% of the advisory fee, and the bonus for subsequent years of the term of the agreement will be in a similar target range. The bonuses payable hereunder will be paid in cash, although at Ambient Advisors’ sole option, they may be paid in stock (or in the form of ten year warrants with cashless exercise provisions, with 1.5 times the number of warrant shares to be issued in lieu of the number of shares of common stock), based upon the average of the closing bid and asked prices for the 5 trading days immediately prior to the awarding to Ambient Advisor of the bonus for a particular year.

Appointment of New President and Chief Executive Officer

On September 15, 2006, our board of directors appointed Marvin S. Hausman, M.D. as President and Chief Executive Officer of OXIS. Dr. Hausman remains the Chairman of the board of directors.

On October 12, 2006, we mutually agreed with Marvin S. Hausman, M.D. to terminate the consulting agreement with NW Medical Research Partners, of which Dr. Hausman is the sole member and manager, effective October 15, 2006. Under the consulting agreement dated October 1, 2005, Dr. Hausman provided certain services pertaining to licensing of intellectual property, development of potential products, financing activities and other issues at the request of our Chief Executive Officer. In conjunction with the termination of the consulting agreement, the board of directors approved the issuance of 330,769 shares of restricted common stock to Dr. Hausman in lieu of cash payment of $67,000 in fees and expenses due under the consulting agreement to the date of termination.

On November 6, 2006, we entered into an employment agreement with Dr. Hausman that commenced retroactively at October 15, 2006. Dr. Hausman will serve as our President and Chief Executive Officer for a three year period from the commencement date of October 15, 2006, and after this period on a year-to-year basis. Dr. Hausman will receive annual compensation in the amount of $250,000, payable quarterly in advance in cash, common stock based on a price equal to 85% of average of the five closing prices for the five trading days prior to the date that the issuance is authorized by the board of directors, or in ten year warrants equal to that number of warrants equal to 1.5 times the number of shares that would otherwise be received. For the initial quarterly payment, Dr. Hausman was issued 347,222 restricted shares of common stock. During the three year term of the agreement, Dr. Hausman will receive an annual bonus based upon the attainment of agreed upon goals and milestones as determined by the board of directors and its compensation committee.

Once we have completed a qualifying financing, the office expense allowance will be paid in cash in advance, commencing for the quarter next following the quarter in which the Qualifying Financing occurred. Additionally, Dr. Hausman will receive family health and dental insurance benefits and short-term and long-term disability policies.

Consulting Agreement with John E. Repine, M.D.

On November 6, 2006, we entered into an consulting agreement with John E. Repine, M.D. that commenced retroactively at October 15, 2006.

Dr. Repine will advise us concerning matters of antioxidant and inflammation research and potential acquisitions (including products/compounds/intellectual property, companies), product research and development, and the development and establishment of reference labs for oxidative stress and inflammatory reactions for a three year period from the commencement date of October 15, 2006, and after this period on a year-to-year basis. Dr. Repine will receive annual compensation in the amount of $36,000, payable quarterly in advance in cash, common stock based on a price equal to 85% of average of the five closing prices for the five trading days prior to the date that the issuance is authorized by the board of directors, or in ten year warrants equal to that number of warrants equal to 1.5 times the number of shares that would otherwise be received. For the initial quarterly payment, Dr. Repine received 50,000 restricted shares of common stock. As part of the compensation under the consulting agreement, OXIS granted Dr. Repine a ten year stock option to purchase 200,000 shares of OXIS common stock at an exercise price of $0.20 per share, vesting as follows: (i) 100,000 option shares vesting in four equal quarterly installments commencing on January 15, 2007 and every three months thereafter and (ii) and the remaining 100,000 option shares vesting in eight quarterly installments over two years. Additionally, we granted Dr. Repine, as a sign on bonus, a non-qualified option to purchase 200,000 shares at exercise price of $0.20 per share, with vesting in six equal installments, commencing on November 14, 2006, through the 180th day after the Commencement Date. During the term of the consulting agreement, Dr. Repine is eligible to receive annual and special bonuses based upon the attainment of agreed upon goals and milestones as determined by our Chief Executive Officer. Each bonus payable will be paid in cash, although at Dr. Repine’s sole option, such bonus may be paid in stock (or in the form of ten year warrants with cashless exercise provisions, with 1.5 times the number of warrant shares to be issued in lieu of the number of shares of common stock), based upon the average of the closing bid and asked prices for the 5 trading days immediately prior to the awarding to Dr. Repine of the particular bonus.

Loan Repayment

On June 1, 2004, we received $1,200,000 in exchange for a note and entered into a loan agreement with our majority stockholder, Axonyx, Inc. We repaid the note on January 6, 2005.

Common Stock Issuance

On December 30, 2004, we sold 12,264,158 shares of common stock and issued warrants to purchase 12,877,366 shares of common stock for $6,500,000 in a private placement with net proceeds of $5,818,000 received in December 2004 and January 2005 after expenses and the cost of the related registration statement. The warrants were issued for the purchase of 6,438,685 shares of common stock at an exercise price of $0.66 per share and 6,438,681 shares of common stock at an exercise price of $1.00 per share.

Acquisition of BioCheck

On September 19, 2005, we entered into a stock purchase agreement with BioCheck and its stockholders to purchase all of its common stock for $6.0 million in cash. BioCheck is a leading producer of enzyme immunoassay diagnostic kits for clinical laboratories. On December 6, 2005, we purchased 51% of the shares of BioCheck’s common stock from each of its stockholders on a pro rata basis for $3,060,000 in cash. This acquisition was accounted for by the purchase method of accounting according to Statement of Financial Accounting Standards No. 141, “Business Combinations.” The consolidated statements of operations include the results of operations of BioCheck from December 6, 2005, the date of acquisition, and the consolidated balance sheets include the assets and liabilities of BioCheck at December 31, 2005 and September 30, 2006. The purchase price of $3,337,000 was based on cash paid to BioCheck’s stockholders of $3,060,000, legal expense of $155,000 and a finder’s fee of $122,000. Pursuant to the stock purchase agreement, OXIS will use its reasonable best efforts to consummate a follow-on financing transaction to raise additional capital with which to purchase the remaining outstanding shares of BioCheck in one or more additional closings.

We have previously disclosed on a Report on Form 8-K filed with the SEC the allocation of acquisition costs and pro forma financials statements related to the acquisition of BioCheck that were based on the information available at that date. The disclosures contained within this prospectus have been presented with the information and using estimates currently available. We may obtain additional independent valuations of BioCheck’s assets related to the acquisition of the remaining 49% of BioCheck and additional acquisition costs may be incurred. Such information and costs may affect the disclosures as presented herein. See Note 2 of the audited consolidated financial statements for the year ended December 31, 2005 for the allocation of the purchase price and other information related to the BioCheck acquisition.

Mutual Services Agreement with BioCheck

On June 23, 2006, we entered into a mutual services agreement with BioCheck. Each of OXIS and BioCheck will provide certain services to the other corporation to be charged monthly at an hourly rate with an overhead surcharge. The services that BioCheck will provide include manufacturing the bulk of our research assay test kits, assisting in packaging and shipping such research assay test kits to our customers, and undertaking research and development of certain new OXIS research assay test kits on a case-by-case basis to be agreed upon between the parties. We will provide services to BioCheck, including marketing and sales, website management and materials requirement and control systems.

The agreement terminates on December 6, 2009, or earlier upon mutual consent of the parties, upon 90 day prior written notice by either party, by either party if a monthly billing is unpaid after 60 days if a 15 day notice and opportunity to cure has been provided, or upon a material breach of the Agreement after 30 days’ notice and opportunity to cure the breach. We owe BioCheck approximately $73,000 for services that BioCheck had provided to us prior to the signing of the Agreement, on or before June 30, 2006. We have not made that payment as of the date of this prospectus. If we receive written notice of breach of the agreement due to this non-payment, it will have 15 days to cure that breach. If we fails to cure the breach during the cure period, BioCheck would have the right to terminate the agreement.

Results of Operations

We expect revenues and expenses to increase substantially as described below from 2005 to 2006 with the consolidation of all of BioCheck’s results of operations for the nine months ended September 30, 2006. BioCheck’s revenues and expenses are not included in the results of operations for the nine months ended September 30, 2005 because they were incurred before the December 6, 2005 date of acquisition. Our projections for 2006 are based upon our expectations that BioCheck will incur similar revenues and costs in 2006 as it incurred in 2005. We can give no assurances that we will be able to successfully merge manufacturing operations without adversely affecting revenues and costs, increase revenues, develop new products, finance our expansion plans and purchase the remaining 49% of the BioCheck common stock we do not own.

The increase in product revenues was primarily attributed to increased sales volume and was comprised of a $272,000 increase in sales to customers within North America and $275,000 of revenues from the operations of BioCheck since December 6, 2005, the date of our acquisition of 51% of BioCheck’s common stock, that was partially offset by a $64,000 decrease in sales to customers outside of North America. We expect revenues, excluding license revenues, to increase by approximately $4.0 million from 2005 to 2006 with the consolidation of BioCheck’s revenues in 2006 over the entire year. 

License revenues are attributed to an exclusive license agreement with HaptoGuard during the third quarter of 2004 and an extension of the license agreement during the fourth quarter of 2005. See Note 12 to the audited consolidated financial statements for the year ended December 31, 2005 included in this prospectus. We are unable to predict when we will receive additional license revenues, if any, because such revenues are dependent upon HaptoGuard successfully receiving regulatory approval and marketing the licensed product.

For the three months ended September 30, the increase in revenues was primarily attributable to the consolidation of $1,128,000 of revenues from BioCheck and $50,000 license fee payment from HaptoGuard that was partially offset by a $198,000 decrease in sales from the OXIS parent company. For the nine months ended September 30, the increase in revenues was primarily attributable to the consolidation of $3,204,000 of revenues from BioCheck and $50,000 license fee payment from HaptoGuard that was partially offset by a $591,000 decrease in sales from the OXIS parent company. The decrease in OXIS parent company sales is attributable to lower sales volume that was caused, in part, by the interruption arising from moving operations from Portland, Oregon to Foster City, California and consolidating our product offerings. We expect fourth quarter 2006 product revenues to increase modestly from the third quarter as we introduce new products such as our improved MPO. We intend to develop new diagnostic test kits and evaluate our product offerings, pricing and distribution network with the plan of increasing sales volume.

The increase in cost of product revenues is attributed to $136,000 of costs from the operations of BioCheck since December 6, 2005, the date of our acquisition of 51% of BioCheck’s common stock. Product costs, other than those for BioCheck, essentially remained the same as our manufacturing facility and personnel were more efficiently utilized in 2005 than in 2004 which offset increased material costs. We expect product costs to increase by approximately $2.0 million from 2005 to 2006 with the consolidation of BioCheck’s cost of product revenues in 2006 over the entire year. Product costs may increase by more than $2.0 million if we successfully increase revenues by an amount greater than the revenues recorded by each individual company in 2005.

Gross profit of $1,152,000 in 2005 was essentially the same as the gross profit of $1,148,000 in 2004 because the additional profits from increased product sales and higher gross profit margins were offset by a $350,000 decrease in license revenues. Excluding license fee revenues, gross profit as a percentage of product revenues increased from 36% in 2004 to 44% in 2005 primarily due to increased sales from 2004 to 2005 with a smaller corresponding increase in costs and higher gross profit margins for BioCheck’s clinical products. With the addition of BioCheck’s revenues in 2006 of $4.0 million that are expected to be approximately 170% of 2005 revenues, gross profit as a percentage of product revenues is expected to increase towards 50% as experienced by BioCheck in 2005.

For the three months ended September 30, 2006, the increase in cost of product revenues is attributable to the consolidation of $512,000 of costs from the operations of BioCheck that were partially offset by decreased labor and related costs including contract labor of $86,000 and facility and related costs of $41,000. For the nine months ended September 30, 2006, the increase in cost of product revenues is attributable to the consolidation of $1,620,000 of costs from the operations of BioCheck that were partially offset by decreased labor and related costs of $115,000 and facility and related costs of $52,000. We expect fourth quarter 2006 product costs to increase proportionally with any increases in revenues.
 
51

Gross profit of $787,000 for the three months ended September 30, 2006 was higher than the gross profit of $199,000 in the comparable period of 2005 because of the additional profits from product sales from BioCheck. Gross profit as a percentage of revenues was 52% in the three months ended September 30, 2006, as compared to 37% in the three months ended September 30, 2005. Gross profit of $2,007,000 for the nine months ended September 30, 2006 was higher than the gross profit of $812,000 in the comparable period of 2005 because of the additional profits from product sales from BioCheck. Gross profit as a percentage of revenues was 46% in the nine months ended September 30, 2006, as compared to 47% in the nine months ended September 30, 2005.

The increase in research and development expenses from 2004 to 2005 is primarily attributed to increased patent amortization expense of $49,000, write-off of abandoned patents of $105,000 and $49,000 of costs from the operations of BioCheck since December 6, 2005, the date of our acquisition of 51% of BioCheck’s common stock. We expect to spend approximately $750,000 on research and development in 2006 primarily at BioCheck. However, the actual amount of research and development expenses will fluctuate with the availability of funding.

For the three months ended September 30, 2006, the increase in research and development expenses is primarily attributable to the consolidation of $131,000 of costs from the operations of BioCheck and increased patent amortization expense of $23,000. The increase was partially offset by decreased salary and benefits costs of $8,000. For the nine months ended September 30, 2006, the increase in research and development expenses is primarily attributable to the consolidation of $432,000 of costs from the operations of BioCheck and increased patent amortization expense of $63,000. The increase was partially offset by decreased salary and benefits costs of $50,000 and direct project expenses of $23,000. We expect fourth quarter 2006 research and development costs to be approximately the same as the third quarter. However, the actual amount of research and development expenses will fluctuate with the availability of funding.

From 2004 to 2005, selling, general and administrative expenses increased approximately $150,000 for accounting and legal activities, $150,000 for marketing consultants, $90,000 for administrative consultants, $70,000 for advertising and promotional literature and $80,000 of costs from the operations of BioCheck since December 6, 2005, the date of our acquisition of 51% of BioCheck’s common stock. These increased costs were partially offset by approximately $40,000 of decreased insurance costs and other cost decreases. We expect selling, general and administrative expenses to increase by approximately $0.8 million from 2005 to 2006 with the consolidation of BioCheck’s selling, general and administrative expenses in 2006 over the entire year. In addition, we plan to implement a marketing campaign to increase revenues. The amount spent on this campaign will depend on the availability of funds.

For the three months ended September 30, 2006, the increase in selling, general and administrative expenses is primarily attributed to the consolidation of costs from the operations of BioCheck of $197,000, severance charges of $261,000 related to the termination of employment of our president and chief executive officer, and increased costs for accounting, legal, stockholder communication and investor relations activities of $20,000; and non-cash compensation of $69,000 which, effective January 1, 2006, is required for employees to be included in expenses by SFAS 123R. The increase was partially offset by decreased costs for labor and related costs including contract labor and associated transportation costs of $28,000. For the nine months ended September 30, 2006, the increase in selling, general and administrative expenses is primarily attributed to the consolidation of costs from the operations of BioCheck of $605,000, severance charges of $261,000 and increased costs for accounting, legal, stockholder communication and investor relations activities of $121,000; labor and related costs including contract labor and associated transportation costs of $74,000; and non-cash compensation of $249,000. We expect fourth quarter 2006 selling, general and administrative expenses to be approximately the same as the third quarter.

Purchased in-process research and development

In connection with our acquisition of 51% of the outstanding shares of BioCheck on December 6, 2005, $1.5 million of purchased in-process research and development was identified as an intangible asset. The applicable research projects were subsequently deemed not to have future uses or markets. As such, this identified intangible asset was expensed in 2005 at the date of acquisition.

Foreign legal proceedings

Foreign legal proceedings during 2004 of $183,000 were related to proceedings of the Autorité des Marchés Financiers, or AMF, and were comprised of legal expenses of $121,000 and fines imposed by the AMF of $62,000 as described in Note 8 to the audited consolidated financial statements for the year ended December 31, 2005 included in this prospectus. We did not incur such expenses in 2005 and do not expect such expenses in 2006.

53
 
Restructuring charges

Restructuring charges during 2004 of $605,000 related to the Axonyx change of control are comprised of legal fees of $196,000, management consulting fees of $34,000, travel expense of $8,000, executive search costs of $22,000 and severance expenses of $345,000. Related to our relocation of operations from Portland, Oregon to Foster City, California, we recorded severance benefits of $119,000 in 2005 that were included in selling, general and administrative expenses, and we expect to incur relocation expenses of approximately $100,000 in 2006.

Financing Fees

In connection with the $570,000 convertible loan financing on January 14, 2004 and the conversion of it into common stock on December 30, 2004, we paid finders’ fees and professional fees of approximately $84,000 and we incurred non-cash financing charges of $411,000 related to the conversion feature of the notes, $159,000 related to initial warrants issued with the notes and $202,000 related to the incentive warrants issued upon conversion of the notes into common stock during 2004.

Interest Income

Interest income was $110,000 in 2005, primarily due to cash available for investment activities obtained in the $6,500,000 equity financing received during December 2004 and January 2005. The decrease in interest income from $74,000 for the nine months ended September 30, 2005 to $45,000 in the same period in 2006 is primarily due to reduced cash available for investment activities obtained in the $6,500,000 equity financing received during December 2004 and January 2005.

Other Income

Other income is related to the sale of surplus equipment.

Interest Expense

Interest expense of $146,000 in the nine months ended September 30, 2006 was primarily due to the loan with KeyBank that was transferred to Bridge Bank incurred in connection with the BioCheck acquisition, the addition of new debt of $600,000 in March 2006 and non-cash financing expense of $45,000 related to the renewal of a note with Fagan Capital. We expect interest expense for the fourth quarter to increase significantly from the third quarter of 2006 with additional debt financing obtained during October 2006. See Notes 3 and 7 to the unaudited consolidated financial statements for the nine months ended September 30, 2006 included in this prospectus.
 
Liquidity and Capital Resources 

On a consolidated basis, we had cash and cash equivalents of $614,000 at December 31, 2005 of which $282,000 was held by BioCheck. We held $332,000 in cash at December 31, 2005, which was not sufficient to sustain our operations through the first quarter of 2006 without additional financings. During March 2006, we received $200,000 from Steven T. Guillen, our resident and chief executive officer at that time, and $400,000 from Fagan Capital, each in exchange for a promissory note.

On a consolidated basis, we had cash and cash equivalents of $677,000 at September 30, 2006 of which $656,000 was held by BioCheck. Since BioCheck has been and is expected to continue to be cash flow positive, management believes that its cash will be sufficient to sustain its operating activities.
 
54

We held $21,000 in cash at our parent level at September 30, 2006. We cannot access the cash held by our majority-held subsidiary, BioCheck, to pay for our parent level operating expenses. We have incurred negative operating cash flows of $0.5 million during the nine months ended September 30, 2006. At our parent level we incurred negative operating cash flows of $0.9 million during the first nine months of 2006. Our cash may not be sufficient to sustain our operations through the first quarter of 2007 without additional financings. We obtained debt financing in which we received proceeds of $1,350,000 subsequent to September 30, 2006 and are seeking equity financing to obtain sufficient funds to sustain operations and purchase the remaining 49% of BioCheck for approximately $3.0 million. From the aforementioned debt financing, $635,000 was used to repay existing debt, accrued interest and related legal fees. We plan to increase revenues by introducing new products. However, we cannot assure you that we will successfully obtain equity financing, if any, sufficient to finance our goals or that we will increase product related revenues as such events are subject to factors beyond our control. If we are unable to raise additional capital in 2007, we will have to curtail or cease operations.

The increase in cash paid to employees is primarily attributed to cash paid by BioCheck for payroll and benefits since December 6, 2005, the date of our acquisition of 51% of BioCheck’s common stock.

The increase in cash paid to suppliers is primarily attributed to increases in selling, general and administrative expenses of approximately $150,000 for accounting and legal activities, $150,000 for marketing consultants, $90,000 for administrative consultants and $70,000 for advertising and promotional literature. In addition, $583,000 of 2004 expenses recorded as liabilities at December 31, 2004 were paid in 2005 and cash expenditures for inventory increased by $108,000.

The increase in cash received from customers is attributed to the $133,000 increase in revenues reduced by the change in accounts receivable.

Interest received increased in 2005 primarily due to cash available for investment activities obtained in the $6,500,000 equity financing received during December 2004 and January 2005.

The increase in cash paid to employees is primarily attributed to $1.0 million of cash paid by BioCheck for payroll and benefits. Cash paid to suppliers is increased by approximately $1.6 million due to BioCheck that was offset by 2004 expenses recorded as liabilities at December 31, 2004 that were paid in the first quarter of 2005 of approximately $0.5 million and an increase in accounts payable and accrued expense in the first nine months of 2006 of approximately $0.5 million. The increase in cash received from customers is attributed to increased revenues of $2.7 million. Interest paid increased primarily due to increased debt entered into during December 2005 of $3,060,000.

Cash used in investing activities

During 2005 we spent $3.2 million on the acquisition of 51% of BioCheck’s common stock and $3.1 million on a restricted certificate of deposit at KeyBank, which was used as collateral under the loan agreement with KeyBank. Capital expenditures were $33,000 and $47,000 in 2005, and 2004 respectively. We had no commitments for capital expenditure at December 31, 2005. We anticipate that in 2006 the BioCheck manufacturing facility in Foster City, California will require expenditures to support our business objective. We spent $172,000 and $262,000 to file patents in 2005 and 2004, respectively.

During the first quarter of 2006 we transferred our $3,060,000 restricted certificate of deposit from KeyBank to Bridge Bank. Capital expenditures during the nine months ended 2006 were primarily for equipment and leasehold improvements at our new Foster City, California location. We had no commitments for capital expenditures at September 30, 2006. We paid $42,000 and $171,000 for patent filings that were capitalized during the nine months ended 2006 and 2005, respectively.

Net cash provided by financing activities

On October 25, 2006, we completed a private placement of debentures and warrants under a securities purchase agreement with four accredited investors. In this financing we issued secured convertible debentures in an aggregate principal amount of $1,694,250 (referred to in this prospectus as the “debentures”), and Series A, B, C, D, and E common stock warrants (referred to in this prospectus as the “warrants”). We also provided the investors registration rights under a registration rights agreement, and a security interest in our assets under a security agreement to secure performance of our duties and obligations under the debentures. Under the warrants, the investors have the right to purchase an aggregate of approximately 14.5 million shares of our common stock, at initial exercise prices ranging from $0.35 to $0.385 per share, and these exercise prices are adjustable according to a full ratchet anti-dilution provision, i.e., the exercise price may be adjusted downward in the event that we conduct a financing at a price per share below $0.35 or $0.385 per share, respectively. The Series D and E warrants are only exercisable pro rata subsequent to the exercise of the Series C warrants. The debentures were issued with an original issue discount of 20.318%, and resulted in proceeds to us of $1,350,000. The debentures are convertible, at the option of the holders, at any time into shares of common stock at $0.35 per share, as adjusted in accordance with a full ratchet anti-dilution provision (referred to in this prospectus as the “conversion price”). Beginning on the first of the month following the earlier of the effective date of the registration statement to be filed pursuant to the registration rights agreement and February 1, 2007, we will amortize the debentures in equal installments on a monthly basis resulting in a complete repayment by the maturity date (the “Monthly Redemption Amounts”). The Monthly Redemption Amounts can be paid in cash or in shares, subject to certain restrictions. If we choose to make any Monthly Redemption Amount payment in shares of common stock, the price per share is the lesser of the conversion price then in effect and 85% of the weighted average price for the ten trading days prior to the due date of the Monthly Redemption Amount. For additional details regarding the terms and conditions of the debentures and warrants, see Exhibits 10.2 and 10.3 to our current report on Form 8-K filed with the SEC on October 26, 2006. The above description is qualified in its entirety by reference to the full text of these instruments.

On March 31, 2006, we issued a $400,000 unsecured promissory note to Fagan Capital. Interest accrues at an annual rate of 8.0% and interest and principal were due on June 2, 2006. On July 26, 2006, Fagan Capital extended the maturity date of the promissory note to June 1, 2007 and we issued to Fagan Capital a warrant to purchase 1,158,857 shares of common stock at an initial exercise price of $0.35 per share. On October 25, 2006, we prepaid the principal, accrued interest and legal fees due in the amount of $426,000. See Note 7 to the unaudited consolidated financial statements included in this prospectus. The purpose of this loan was to provide us with short term financing as we sought longer term financing.

On March 10, 2006, we received $200,000 in exchange for an unsecured promissory note with Steven T. Guillen, our president and chief executive officer at that time. The related party note bears interest at 7.0%. Interest and principal were due on September 10, 2006. Mr. Guillen’s employment was terminated on September 15, 2006. We were in default on this note at September 30, 2006. Subsequent to September 30, 2006, Mr. Guillen sued the Company for payment of interest and principal due under the note. On November 2, 2006, we repaid the principal and accrued interest due on the promissory note with Mr. Guillen in the amount of $209,000.

On December 2, 2005, we entered into non-revolving one-year loan agreement with KeyBank in the amount of $3,060,000, for the purpose of completing the initial closing of the BioCheck acquisition. This loan was repaid during February 2006 and a new one-year loan agreement for $3,060,000 was entered into at Bridge Bank. Steven T. Guillen, our -president and chief executive officer at that time, purchased 600,000 shares of common stock for $240,000, pursuant to the terms of an employment agreement on February 28, 2005.

On June 1, 2004, we received $1,200,000 in exchange for a note and entered into a loan agreement with our majority stockholder at the time, Axonyx, Inc. We repaid the note on January 6, 2005. In a $6,500,000 private placement of our common stock on December 30, 2004, we received net proceeds of $5,818,000 in exchange for 12,264,158 shares of common stock which were issuable at December 31, 2004.

The cash held by us of $332,000 at December 31, 2005 was not sufficient to sustain its operations through the first quarter of 2006 without additional financings. During March 2006, we received $200,000 from Steven T. Guillen, our -president and chief executive officer at that time, and $400,000 from Fagan Capital, each in exchange for a promissory note.

We had cash and cash equivalents of $21,000 at the parent level at September 30, 2006. We cannot access the cash held by its majority-held subsidiary, BioCheck, to pay for our operating expenses at the parent level. In an effort to mitigate this near-term concern, we obtained debt financing in which we received proceeds of $1,350,000 subsequent to September 30, 2006 and are seeking equity financings to obtain sufficient funds to sustain operations and purchase the remaining 49% of BioCheck for approximately $3.0 million. From the aforementioned debt financing, $635,000 was used to repay existing debt, accrued interest and related legal fees. However, we cannot assure you that we will successfully obtain equity financing.

Commitments and Contingencies

Our partial subsidiary, BioCheck, leases facilities under operating leases in Foster City, California that expire in December 2008. During 2004, BioCheck entered into a sublease of an unused Foster City, California facility to the end of the lease term in 2008 that reduced our operating lease commitments. Net minimum lease payments to which we are committed under these leases at December 31, 2005 are $227,000 in 2006, $201,000 in 2007 and $208,000 in 2008. In addition, we entered into an operating lease for 4,136 square feet of space adjacent to space occupied by our BioCheck subsidiary in Foster City, California starting on April 1, 2006 and ending on March 31, 2009. The annual base rent under the lease agreement begins at $62,000 per year and increases incrementally to $66,000 by the end of the lease term.

We estimate that our cost of relocating operations from Portland, Oregon to Foster City, California was approximately $100,000. In addition to these expenses, and as part of the relocation of operations, we offered all affected regular full-time employees whose employment was terminated severance benefits estimated in total to be $119,000.

At December 31, 2005, we had a commitment to purchase Ergothioneine manufactured by Cambridge Major Labs for $179,000 and we have a contract with them to purchase additional Ergothioneine as needed.

On September 19, 2005, we entered into a stock purchase agreement with BioCheck and its stockholders to purchase all of its common stock for $6.0 million in cash. On December 6, 2005, we purchased 51% of the common stock of BioCheck. Pursuant to the stock purchase agreement, we will use our reasonable best efforts to consummate a follow-on financing transaction to raise additional capital with which to purchase the remaining outstanding shares of BioCheck in one or more additional closings. The purchase price will be increased by an additional 8% per annum from December 6, 2005. If we have not purchased all of the outstanding shares of BioCheck within twelve months of December 6, 2005, the earnings before interest, taxes, depreciation and amortization expenses, if any, of BioCheck, will be used to repurchase the remaining outstanding BioCheck shares at one or more additional closings.

As described above, on October 25, 2006 we completed a convertible debenture and warrant financing under a securities purchase agreement with accredited investors. In this financing, we issued secured convertible debentures in an aggregate principal amount of $1,694,250. We also provided the investors registration rights under a registration rights agreement, and a security interest in our assets under a security agreement to secure to secure the performance of our duties and obligations under the debentures. The debentures were issued with an original issue discount of 20.318%, and resulted in proceeds to us of $1,350,000. The debentures are convertible, at the option of the holders, at any time into shares of common stock at $0.35 per share, as adjusted in accordance with a full ratchet anti-dilution provision (referred to in this prospectus as the “conversion price”). Beginning on the first of the month following the earlier of the effective date of the registration statement to be filed pursuant to the registration rights agreement and February 1, 2007, we will amortize the debentures in equal installments on a monthly basis resulting in a complete repayment by the maturity date (the “Monthly Redemption Amounts”). The Monthly Redemption Amounts can be paid in cash or in shares, subject to certain restrictions. If we choose to make any Monthly Redemption Amount payment in shares of common stock, the price per share is the lesser of the conversion price then in effect and 85% of the weighted average price for the ten trading days prior to the due date of the Monthly Redemption Amount.

The performance of our duties and obligations under the debentures are secured by substantially all of our assets under a security agreement. As additional security to the debenture holders, we have also pledged the shares we hold in our subsidiaries, including 51% of BioCheck, Inc., and all of the shares of capital stock of our wholly-owned subsidiaries, OXIS Therapeutics, Inc. and OXIS Isle of Man Limited. In addition, OXIS Therapeutics, Inc. and OXIS Isle of Man Limited, have each entered into a subsidiary guarantee under which these subsidiaries have guaranteed the performance, at the parent level, of our obligations under the debentures.

Critical Accounting Policies

Our accounting policies are explained in Note 1 to the audited consolidated financial statements for the year ended December 31, 2005 and Note 1 to the unaudited consolidated financial statements for the nine months ended September 30, 2006 included in this prospectus. We consider the following accounting policies to be critical given they involve estimates and judgments made by management and are important for our investors’ understanding of our operating results and financial condition.

Basis of Consolidation

The consolidated financial statements contained in this prospectus include the accounts of OXIS International, Inc. and its subsidiaries. All intercompany balances and transactions have been eliminated. On December 6, 2005, we purchased 51% of the common stock of BioCheck. This acquisition was accounted for by the purchase method of accounting according to Statement of Financial Accounting Standards, or SFAS, No. 141, “Business Combinations.” The consolidated statements of operations include the results of operations of BioCheck from December 6, 2005, the date of acquisition, and the consolidated balance sheets include the assets and liabilities of BioCheck at December 31. 2005 and September 30, 2006.

Revenue Recognition

We manufacture, or have manufactured on a contract basis, research and diagnostic assays and fine chemicals, which are our primary products sold to customers. Revenue from the sale of our products, including shipping fees, is recognized when title to the products is transferred to the customer which usually occurs upon shipment or delivery, depending upon the terms of the sales order and when collectibility is reasonably assured. Revenue from sales to distributors of our products is recognized, net of allowances, upon delivery of product to the distributors. According to the terms of individual distributor contracts, a distributor may return product up to a maximum amount and under certain conditions contained in its contract. Allowances are calculated based upon historical data, current economic conditions and the underlying contractual terms. Our mix of product sales are substantially at risk to market conditions and demand, which may change at anytime.
 
59

We recognize license fee revenue for licenses to our intellectual property when earned under the terms of the agreements. Generally, revenue is recognized upon transfer of the license unless we have continuing obligations for which fair value cannot be established, in which case the revenue is recognized over the period of the obligation. We consider all arrangements with payment terms extending beyond 12 months not to be fixed or determinable. In certain licensing arrangements there is provision for a variable fee as well as a non-refundable minimum amount. In such arrangements, the amount of the non-refundable minimum guarantee is recognized upon transfer of the license and collectibility is reasonably assured or over the period of the obligation, as applicable, and the amount of the variable fee is recognized as revenue when it is fixed and determinable. We recognize royalty revenue based on reported sales by third party licensees of products containing our materials, software and intellectual property. Non-refundable royalties, for which there are no further performance obligations, are recognized when due under the terms of the agreements.

Inventories

Inventories are stated at the lower of cost to purchase and/or manufacture the inventory or the current estimated market value of the inventory. We regularly review our inventory quantities on hand and record a provision for excess and obsolete inventory based primarily on our estimated forecast of product demand and/or our ability to sell the products and production requirements. Demand for our products can fluctuate significantly. Factors which could affect demand for our products include unanticipated changes in consumer preferences, general market conditions or other factors, which may result in cancellations of advance orders or a reduction in the rate of reorders placed by customers and/or continued weakening of economic conditions. Additionally, our estimates of future product demand may be inaccurate, which could result in an understated or overstated provision required for excess and obsolete inventory. Our estimates are based upon our understanding of historical relationships which can change at anytime.

Long-Lived Assets

Our long-lived assets include property, plant and equipment, capitalized costs of filing patent applications and goodwill and other assets. See Notes 1, 4, 5 and 6 to the audited consolidated financial statements for the year ended December 31, 2005 included in this prospectus for more detail regarding our long-lived assets. We evaluate our long-lived assets for impairment in accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Estimates of future cash flows and timing of events for evaluating long-lived assets for impairment are based upon management’s judgment. If any of our intangible or long-lived assets are considered to be impaired, the amount of impairment to be recognized is the excess of the carrying amount of the assets over its fair value. The net carrying values of long-lived assets at December 31, 2005, subject to possible impairment charges in the future, are presented by location in the following table below:

Applicable long-lived assets are amortized or depreciated over the shorter of their estimated useful lives, the estimated period that the assets will generate revenue, or the statutory or contractual term in the case of patents. Estimates of useful lives and periods of expected revenue generation are reviewed periodically for appropriateness and are based upon management’s judgment. Goodwill and other assets are not amortized.
 
60

Certain Expenses and Liabilities

On an ongoing basis, management evaluates its estimates related to certain expenses and accrued liabilities. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions.
Share-Based Compensation

In December 2004, the FASB issued SFAS 123R, which replaces FASB Statement No. 123, “Accounting for Stock-Based Compensation”, and supersedes APB Opinion No. 25, “Accounting for Stock Issued to Employees,” or APB Opinion No. 25. SFAS 123R establishes standards for the accounting for share-based payment transactions in which an entity exchanges its equity instruments for goods or services. It also addresses transactions in which an entity incurs liabilities in exchange for goods or services that are based on the fair value of the entity’s equity instruments or that may be settled by the issuance of those equity instruments. SFAS 123R covers a wide range of share-based compensation arrangements including share options, restricted share plans, performance-based awards, share appreciation rights and employee share purchase plans. SFAS 123R requires a public entity to measure the cost of employee services received in exchange for an award of equity instruments based on the fair value of the award on the grant date (with limited exceptions). That cost will be recognized in the entity’s financial statements over the period during which the employee is required to provide services in exchange for the award. Management implemented SFAS 123R effective January 1, 2006. Methodologies used for calculations such as the Black-Scholes option-pricing models and variables such as volatility and expected life are based upon management’s judgment. Such methodologies and variables are reviewed and updated periodically for appropriateness and affect the amount of recorded charges. See Note 1 to the unaudited consolidated financial statements for the six months ended June 30, 2006 included in this prospectus for more information on the amounts, methodologies and variables related to non-cash share-based compensation charges.

Inflation 

We believe that inflation has not had a material adverse impact on our business or operating results during the periods presented.

Off-balance Sheet Arrangements

We have no off-balance sheet arrangements.

Changes or Disagreements with Accountants

There were no changes in, or disagreements with, our independent registered public accounting firm during 2004 or 2005.

Audit Committee and Audit Committee Financial Expert
 
We are not a “listed company” under SEC rules and are therefore not required to have an audit committee comprised of independent directors. We do, however, have an audit committee consisting of three members of our board of directors, including S. Colin Neill, John E. Repine, M.D., and Gary M. Post. The board of directors has determined that S. Colin Neill, the Chairman of our Audit Committee, qualifies as an “audit committee financial expert” as defined by the rules of the Securities and Exchange Commission. In addition, the board of directors has determined that each of the members of the audit committee is able to read and understand fundamental financial statements and has substantial business experience that results in that member's financial sophistication. Accordingly, the board of directors believes that each member of the audit committee has sufficient knowledge and experience necessary to fulfill such member’s duties and obligations as an audit committee member.

In-the-money options represents unexercised options having a per share exercise price below $0.205, the closing price of our common stock at December 29, 2006. The value of unexercised in-the-money options equals the number of in-the-money options multiplied by the excess of $0.205 over the per-share exercise prices of the options. The value of unexercised in-the-money options at December 31, 2006, may never be realized by the option holders.
 
Director Compensation
 
We pay an annual fee of $4,000 to each non-employee director and an additional $1,000 to non-employee directors for serving as committee chair. During 2006, while we did not make payments under this policy, such expenses were accrued. We do not pay meeting fees but directors are reimbursed for their expenses incurred in attending meetings. Employee directors receive no other compensation as directors.
 
Under our 2003 Stock Incentive Plan, non-employee directors are automatically awarded options to purchase 30,000 shares of common stock upon becoming directors and automatically awarded options to purchase 5,000 shares of common stock annually after this date.

Employment Agreements
 
On February 28, 2005, we entered into a Letter Agreement, effective as of February 28, 2005, with Steven T. Guillen. The terms of the Letter Agreement included, but were not limited to, the following:
 
·  
Mr. Guillen would serve as our President and Chief Executive Officer;
 
·  
Mr. Guillen’s initial annual base salary was fixed at $250,000, subject to annual salary and performance reviews and potential salary increases at the sole discretion of the Board;
 
·  
Mr. Guillen was eligible for a performance-based bonus determined at the discretion of the Board, the range of which was expected to be between 25% and 50% of Mr. Guillen’s annual base salary, depending upon the attainment of certain goals to be mutually agreed upon between Mr. Guillen and the Board;
 
·  
Mr. Guillen received irrevocable stock option grants in the aggregate amount of 600,000 shares of our common stock under our 2003 Stock Incentive Plan, and pursuant to a standalone grant outside of the plan;
 
·  
Mr. Guillen’s options would have an exercise price of $0.40 per share;
 
·  
Mr. Guillen would be entitled to full vesting of the then-unvested shares subject to the irrevocable stock option grants upon a “Change of Control” to include, in general, a merger, consolidation, or reorganization of the company, a sale of substantially all of our assets, a corporate transaction resulting in a change of control of our company, a change control of our board of directors, or upon Mr. Guillen’s termination of his employment with our company for “Good Reason” (as the above terms are defined in the Letter Agreement) (referred to as the “Acceleration Events”);
 
68
 
·  
Mr. Guillen would purchase 600,000 fully-vested shares of our common stock, at the then-current market price of $0.40 per share from the pool of shares reserved in our 2003 Stock Incentive Plan;
 
·  
Mr. Guillen would become a member of our board of directors; and
 
·  
As further described and qualified in the Letter Agreement, Mr. Guillen was entitled to receive certain severance benefits, including payments equal to one month of his base salary for a period of 12 months, in the event that: (i) we terminated his employment without “cause” (as defined in the Letter Agreement), (ii) within twelve months after a Change of Control, Mr. Guillen terminated his employment with “good reason” (as defined in the Letter Agreement) or (iii) Mr. Guillen’s employment terminated as a result of his death or disability (each a “Severance Termination”).
 
On September 15, 2006, Mr. Guillen’s employment as President and Chief Executive Officer was terminated by the board of directors.

On January 6, 2006 we signed a Letter Agreement with Michael D. Centron outlining the basic terms of his employment with us as Vice President and Chief Financial Officer. On the same day our board of directors ratified the Letter Agreement and granted stock options to Mr. Centron pursuant to the terms of the Letter Agreement. Under the terms of the Letter Agreement:
 
·  
Mr. Centron was entitled to a base salary of $150,000 per year with eligibility for a twenty percent performance based annual bonus;
 
·  
Mr. Centron was granted a ten year incentive stock option to purchase 150,000 shares of our common stock at an exercise price of $0.30 per share, to be vested as follows: 25% vest immediately, 25% vest on January 6, 2007, 25% vest on January 6, 2008 and 25% vest on January 6, 2009.
 
·  
Mr. Centron was entitled to receive certain severance payments and benefits in the event that we terminated his employment without “cause”, as defined in the Letter Agreement, if Mr. Centron terminated his employment with “good reason”, as defined in the Letter Agreement, within twelve months after a change of control (as defined in our 2003 Incentive Stock Plan), or in the event that Mr. Centron’s employment terminated as a result of his death or disability (any of the above referred to as a “Severance Termination”).
 
·  
In the event of a Severance Termination, Mr. Centron would have received a payment equal to three months of his then effective base salary. In addition, the exercise period for any options vested as of the termination date would have been extended until the later of January 6, 2011 or the third anniversary of the termination date, provided however that no exercise of options would have been allowed after the expiration of their term.

Mr. Centron resigned as an officer and employee effective November 15, 2006.

On November 6, 2006, we entered into an employment agreement with Dr. Hausman that commenced retroactively at October 15, 2006, referred to as the commencement date. Under the terms of our agreement:
 
·  
Dr. Hausman will serve as our President and Chief Executive Officer for a three year term from the commencement date of his employment, and after this period, on a year-to-year basis;
 
 
69
 
 
·  
Dr. Hausman will receive annual compensation in the amount of $250,000, payable quarterly in advance in cash, common stock based on a price equal to 85% of average of the five closing prices for the five trading days prior to the date that the issuance is authorized by the board of directors, or in ten year warrants equal to that number of warrants equal to 1.5 times the number of shares that would otherwise be received;
 
·  
For the initial quarterly payment, Dr. Hausman was issued 347,222 restricted shares of common stock;
 
·  
During the three year term of the agreement, Dr. Hausman will receive an annual bonus based upon the attainment of agreed upon goals and milestones as determined by the board of directors and its compensation committee;
 
·  
During the remainder of calendar year 2006, Dr. Hausman’s bonus will be pro rated on an annual bonus rate in the range of 25% to 50% of his base salary, and the bonus for subsequent years of the term of the agreement will be in a similar target range;
 
·  
The bonuses payable will be paid in cash, although at Dr. Hausman’s sole option, they may be paid in stock (or in the form of ten year warrants with cashless exercise provisions, with 1.5 times the number of warrant shares to be issued in lieu of the number of shares of common stock), based upon the average of the closing bid and asked prices for the 5 trading days immediately prior to the awarding to Dr. Hausman of the bonus for a particular year;
 
·  
Once we have raised at least $2.5 million in one or more financings (equity, debt or convertible debt, in addition to the financing closed on October 25, 2006) or in a strategic transaction, Dr. Hausman may elect, at any time, in lieu of receiving a quarterly issuance of stock (or warrants in lieu thereof), to receive his base salary in cash, payable monthly on our regular pay cycle for professional employees;
 
·  
As part of his compensation, we granted Dr. Hausman a ten year a non-qualified option to purchase 495,000 shares of our common stock at an exercise price of $0.20 per share, vesting as follows: (i) 247,500 option shares vesting in four equal quarterly installments commencing on January 15, 2007 and every three months thereafter and (ii) and the remaining 247,500 option shares vesting in eight quarterly installments over two years;
 
·  
Additionally, we granted Dr. Hausman, as a sign on bonus, 500,000 restricted shares of common stock and a ten year common stock purchase warrant to purchase 1,505,000 shares at an exercise price of $0.20 per share, with vesting in six equal installments, commencing on November 14, 2006, through the 180th day after the Commencement Date;
 
·  
We are providing Dr. Hausman with an annual office expense allowance of $50,000, for the costs of maintaining an office in the Stevenson, Washington area, payable quarterly in advance in the form of common stock, at a price equal to 85% of the market price;
 
·  
For the first installment, representing $12,500 of the above office expense allowance, Dr. Hausman was issued 69,444 restricted shares of common stock;
 
·  
Once we have completed a qualifying financing, the above office expense allowance will be paid in cash in advance, commencing for the quarter next following the quarter in which the Qualifying Financing occurred.
 
·  
Additionally, Dr. Hausman will receive family health and dental insurance benefits and short-term and long-term disability policies;
 
·  
Upon termination for cause, all compensation due to Dr. Hausman under the agreement will cease, other than a right to participate in continued group health insurance for a certain period of time (this applies to all terminations, except if Dr, Hausman terminates without good reason) and any unexercised portions of his stock options shall expire upon such termination;
 
 
70
 
 
·

On October 12, 2006, we mutually agreed with Marvin S.

Under the consulting agreement dated October 1, 2005, Dr. Hausman provided certain services pertaining to licensing of intellectual property, development of potential products, financing activities and other issues. In conjunction with the termination of the consulting agreement, the board of directors approved the issuance of 330,769 shares of restricted common stock to Dr. Hausman in lieu of cash payment of $67,000 in fees and expenses due under the consulting agreement to the date of termination.

Engagement Letter and Advisory Agreement with Director

On May 12, 2006, we entered into an engagement letter with Ambient Advisors LLC. Gary M. Post, a member of our board of directors, is the manager of Ambient Advisors. Ambient Advisors provided certain services pertaining to strategic planning, investor communications and financing strategies and other projects at the request of our chief executive officer for a one year period in return for monthly compensation of $5,000. We granted Ambient Advisors a ten year warrant to purchase 108,000 shares of our common stock at an exercise price of $0.39 per share, with 9,000 shares becoming exercisable each month over the term of the agreement. On October 12, 2006, we mutually agreed with Gary M. Post to terminate the engagement letter with Ambient Advisors LLC, effective October 15, 2006, replace it with a new consulting agreement and accelerate the vesting of the warrant to be fully vested effective October 15, 2006.

On November 6, 2006, we entered into an advisory agreement with Ambient Advisors that commenced retroactively at October 15, 2006. Ambient Advisors will provide certain services pertaining to strategic planning, financial planning and budgeting, investor relations, corporate finance and such additional roles and responsibilities as requested for a three year period beginning from October 15, 2006, and after this date on a year-to-year basis. Ambient Advisors will receive annual compensation in the amount of $83,333, payable quarterly in advance in cash, common stock based on a price equal to 85% of average of the five closing prices for the five trading days prior to the date that the issuance is authorized by the board of directors, or in ten year warrants equal to that number of warrants equal to 1.5 times the number of shares that would otherwise be received. For the initial quarterly payment, Ambient Advisors received a ten year warrant to purchase 173,608 shares of common stock with an exercise price of $0.20 per share, vesting immediately. As part of the compensation, we granted Ambient Advisors a ten year common stock purchase warrant to purchase 550,000 shares of our common stock at an exercise price of $0.20 per share, vesting as follows: (i) 275,000 warrant shares vesting in four equal quarterly installments commencing on January 15, 2007 and every three months thereafter and (ii) and the remaining 275,000 warrant shares vesting in eight quarterly installments over two years.

During the three year term of the agreement, Ambient Advisors will receive an annual bonus based upon the attainment of agreed upon goals and milestones as determined by our board of directors or compensation committee. During the remainder of calendar year 2006, Ambient Advisors’ bonus will be pro rated on an annual bonus rate in the range of 25% to 50% of the advisory fee, and the bonus for subsequent years of the term of the agreement will be in a similar target range. The bonuses payable under our agreement with Ambient Advisors will be paid in cash, although at Ambient Advisors’ sole option, they may elect to receive compensation in stock (or in the form of ten year warrants with cashless exercise provisions, with 1.5 times the number of warrant shares to be issued in lieu of the number of shares of common stock), based upon the average of the closing bid and asked prices for the 5 trading days immediately prior to the awarding to Ambient Advisors of the bonus for a particular year.

If we terminate our agreement with Ambient Advisors without cause after the six month anniversary of November 6, 2006, Ambient Advisors shall receive an amount equal to twelve months of the advisory fee in a lump sum payment and all outstanding stock options shall become fully vested and the warrants vested as of the date of termination and the stock options shall remain exercisable through their respective expiration dates. If we terminate our agreement with Ambient Advisors without cause prior the six month anniversary of November 6, 2006, Ambient Advisors will be paid any expenses due to it and all vested stock options and warrants shall remain exercisable through their respective expiration dates. If we terminate Ambient Advisors for cause, Ambient Advisors will not be entitled to any further payments of its advisory fee, and any unexercised stock options will expire. If Ambient Advisors resigns for whatever reason, or if Gary M. Post dies or becomes disabled, Ambient Advisors will not be entitled to any further payments of the advisory fee under our agreement, all unvested stock options and warrants will expire, and all vested stock options and warrants will remain exercisable until their respective expiration dates.

Holders of shares of our common stock are entitled to one vote for each share on all matters to be voted on by the stockholders. Holders of shares of our common stock have no cumulative voting rights. Holders of shares of our common stock are entitled to share ratably in dividends, if any, as may be declared, from time to time by our board of directors in its discretion, from funds legally available for any such dividends. In the event of a liquidation, dissolution or winding up of our company, the holders of shares of its common stock are entitled to their pro rata share of all assets.

Preferred Stock

Our preferred stock may be divided into such number of series as our board of directors may determine. Our board of directors is authorized to determine and alter the rights, preferences, privileges and restrictions granted to and imposed upon any wholly unissued series of preferred stock, and to fix the number of shares of any series of preferred stock and the designation of any such series of preferred stock. As long as they stay within the limits and restrictions of any prior resolution or resolutions originally fixing the number of shares constituting any series of preferred stock, our board of directors may increase or decrease (but not below the number of shares of such series outstanding at that time) the number of shares of any series subsequent to the issue of shares of that series.
 
As of the date of this prospectus 96,230 shares of Series C Preferred Stock are outstanding. Each issued and outstanding share of our Series C Preferred Stock is fully paid and non-assessable.
 
Conversion Rights
 
Each share of Series C Preferred Stock was initially convertible into one share of our common stock. On October 21, 1998, however, we effected a 1-for-5 reverse stock split of our shares of common stock. While the reverse stock split did not affect the number of shares of Series C Preferred Stock outstanding, it did affect the conversion ratio for such shares. As a result of the reverse stock split, each share of Series C Preferred Stock is currently convertible into 0.2889 shares of our common stock. The conversion ratio is based on the average closing bid price of the common stock for the fifteen consecutive trading days ending on the date immediately preceding the date notice of conversion is given, but cannot be less than .20 nor more than .2889 common shares for each Series C Preferred share. The conversion ratio may be adjusted under certain circumstances such as stock splits or stock dividends.

80
 

We have a right to convert shares of Series C Preferred into shares of common stock automatically if at any time the average closing bid price of our common stock for 15 consecutive trading days is equal to or greater than $2.60.

Voting Rights
 
Shares of Series C Preferred Stock generally vote with shares of common stock, and have a number of votes equal to the number of shares of common stock into which they could convert. As such, on most matters shares of Series C Preferred Stock have 1/5th of a vote per share.
 
Holders of a majority of the outstanding shares of Series C Preferred Stock voting separately as a separate class, must consent prior to us taking any action which alters or changes any of the rights, privileges or preferences of the Series C Preferred Stock, including without limitation increasing or decreasing the aggregate number of authorized shares of such series other than an increase incident to a stock split.
 
If we propose to merge or consolidate with or into another corporation, or sell, lease or convey all or substantially all of its assets, we are required to send to holders of Series C Preferred Stock notice of the proposal at least twenty (20) days prior to taking such action.
 
Liquidation Preference
 
Shares of Series C Preferred Stock participate on an equal basis with the holders of the common stock (as if the Series C Preferred Stock had converted into common stock) in any distribution of any of the assets or surplus funds of our company.
 
Convertible Debentures
 
On October 25, 2006, we issued we issued convertible debentures with an aggregate principal amount of $1,694,250 to the Purchasers. The debentures were issued with an original issue discount of 20.318%, and resulted in proceeds to us of $1,350,000. The debentures are convertible, at the option of the holders, at any time into shares of common stock at $0.35 per share, as adjusted in accordance with a full ratchet anti-dilution provision (referred to in this prospectus as the “conversion price”). Beginning on the first of the month following the earlier of the effective date of the registration statement to be filed pursuant to the registration rights agreement and February 1, 2007, we will amortize the debentures in equal installments on a monthly basis resulting in a complete repayment by the maturity date (the “Monthly Redemption Amounts”). The Monthly Redemption Amounts can be paid in cash or in shares, subject to certain restrictions. If we choose to make any Monthly Redemption Amount payment in shares of common stock, the price per share is the lesser of the conversion price then in effect and 85% of the weighted average price for the ten trading days prior to the due date of the Monthly Redemption Amount.
 
The performance of our duties and obligations under the debentures are secured by substantially all of our assets under a security agreement. As additional security to the debenture holders, we have also pledged the shares we hold in our subsidiaries, including 51% of BioCheck, Inc., and all of the shares of capital stock of our wholly-owned subsidiaries, OXIS Therapeutics, Inc. and OXIS Isle of Man Limited. In addition, OXIS Therapeutics, Inc. and OXIS Isle of Man Limited, have each entered into a subsidiary guarantee under which these subsidiaries have guaranteed the performance, at the parent level, of our obligations under the debentures.
 
81
 
 
Warrants
 
On October 25, 2006 in conjunction with the issuance of the debentures, we also issued (1) five year Series A warrants to purchase an aggregate of 2,420,357 shares of common stock at an initial exercise price of $0.35 per share, (2) one year Series B warrants to purchase 2,420,357 shares of common stock at an initial exercise price of $0.385 per share, (3) two year Series C warrants to purchase an aggregate of 4,840,714 shares of common stock at an initial exercise price of $0.35 per share, (4) six year Series D warrants to purchase 2,420,357 shares of common stock have an initial exercise price of $0.35 per share, which become exercisable on a pro-rata basis only upon the exercise of the Series C warrants, and (5) six year Series E warrants to purchase 2,420,357 shares of common stock with an initial exercise price of $0.385 per share, which similar to the Series D warrants, become exercisable on a pro-rata basis only upon the exercise of the Series C warrants. The initial exercise prices for each warrant are adjustable pursuant to a full ratchet anti-dilution provision and upon the occurrence of a stock split or a related event.
 
Registration Rights

We have agreed to file a registration statement to register the common stock underlying the debentures and warrants described above on or before December 9, 2006, and cause the registration statement to become effective on or before February 22, 2007. We will be obligated to pay the investors a monthly penalty of 2% (up to a maximum of 36%) of the offering amount if we fail to meet the foregoing registration deadlines, until the registration statement becomes effective. For additional details regarding the terms and conditions of the registration rights agreement, see Exhibit 10.4 to our current report on Form 8-K filed with the SEC on October 26, 2006. The above description is qualified in its entirety by reference to the full text of this agreement.

Registration of these shares of common stock upon exercise of these registration rights would result in the holders being able to trade these shares without restriction under the Securities Act once the applicable registration statement is declared effective. We have agreed to pay all registration expenses related to the registration of these shares of common stock. All registration rights terminate, as to any individual holder, when the holder can sell all of the holder’s shares pursuant to Rule 144(k) under the Securities Act.
 
Anti-Takeover Provisions and Delaware Law
 
Certificate of Incorporation and Bylaws
 
Some provisions of Delaware law and our certificate of incorporation and bylaws contain provisions that could make the following transactions more difficult:
 
 
 
·
 
 
 
acquisition of us by means of a tender offer;
 
 
 
·
 
 
 
acquisition of us by means of a proxy contest or otherwise; or
 
  
 
·
 
 
 
removal of our incumbent officers and directors.
 
These provisions, summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids and to promote stability in our management. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors.
 
 
 
 
 · 
 
 
 
Undesignated Preferred Stock.    The ability to authorize undesignated preferred stock makes it possible for our board of directors to issue one or more series of preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of us. These and other provisions may have the effect of deterring hostile takeovers or delaying changes in control or management of our company.
 
82
 

 
  
 
 · 
 
 
 
Stockholder Meetings.    Our charter documents provide that a special meeting of stockholders may be called only by the chairman of the board, by our president, or by a resolution adopted by a majority of our board of directors.
 
  
 
 · 
 
 
 
Requirements for Advance Notification of Stockholder Nominations and Proposals.    Our bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors or a committee of the board of directors.
 
  
 
 · 
 
 
 
No Stockholder Action by Written Consent.    Under our certificate of incorporation, our stockholders may not act by written consent without a meeting.
 
  
 
 · 
 
 
 
Board of Directors.    Our certificate of incorporation and bylaws provide that, subject to any rights of holders of preferred stock to elect additional directors under specified circumstances, the number of directors will be fixed from time to time exclusively by resolution by the board of directors. In addition, subject to any rights of holders of preferred stock, newly created directorships resulting from any increase in the number of directors and any vacancies on the board of directors resulting from death, resignation, disqualification, removal or other cause will be filled by the affirmative vote of a majority of the remaining directors then in office, even if less than a quorum, and not by the stockholders. No decrease in the number of directors constituting the board of directors will shorten the term of any incumbent director. Subject to the rights of holders of preferred stock, generally any director may be removed from office by the affirmative vote of the holders of at least a majority of our outstanding common stock.
 
  
 
 · 
 
 
 
Supermajority Approval of Certain Corporate Actions.    Under our certificate of incorporation, the affirmative vote of two-thirds of our outstanding stock is required for us to take the following actions: (a) to approve the lease, sale, exchange or transfer or other disposition of all or substantially all of our assets or business to a related company or its affiliate; to consolidate or merge with a related company or its affiliate; or to acquire substantially all of the assets of a corporation, or the securities representing such assets, in which we are the acquiring corporation and our voting shares are issued or transferred to a related company or its affiliate, or to stockholders of a related company, its affiliate or an associated person; (b) to approve any agreement providing for any action in (a), or (c) to amend our certificate of incorporation to change the provisions of the section that requires supermajority approval of such actions. For purposes of this section, “related company” is defined as any person or entity which together with affiliates or associated persons, owns 10% of our outstanding shares. In addition, with respect to any such transaction, our stockholders will be entitled to dissenting stockholder rights under Section 262 of the Delaware General Corporation Law or as provided for in our certificate of incorporation.
 
 
 
 · 
 
 
 
No Cumulative Voting. Our certificate of incorporation and bylaws do not provide for cumulative voting in the election of directors. Cumulative voting provides for a minority stockholder to vote a portion or all of its shares for one or more candidates for seats on the board of directors. Without cumulative voting, a minority stockholder will not be able to gain as many seats on our board of directors based on the number of shares of our stock that such stockholder holds than if cumulative voting were permitted and makes it more difficult for a minority stockholder to gain a seat on our board of directors to influence the board of directors’ decision regarding a takeover.
 
83
 
Delaware Anti-Takeover Statute
 
We are subject to Section 203 of the Delaware General Corporation Law. This law prohibits a publicly-held Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an interested stockholder unless:
 
 
 
 · 
 
 
 
prior to the date of the transaction, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;
 
  
 
 · 
 
 
 
upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding those shares owned by persons who are directors and also officers and by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or
 
  
 
 · 
 
 
 
on or subsequent to the date of the transaction, the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least two-thirds of the outstanding voting stock which is not owned by the interested stockholder.
 
Section 203 defines “business combination” to include:
 
  
 
 · 
 
 
 
any merger or consolidation involving the corporation and the interested stockholder;
 
  
 
 · 
 
 
 
any sale, transfer, pledge or other disposition of 10% or more of our assets involving the interested stockholder;
 
  
 
 · 
 
 
 
in general, any transaction that results in the issuance or transfer by us of any of our stock to the interested stockholder;
 
 
 
 · 
 
 
 
in general, any transaction that has the effect of increasing the proportionate share of our stock of any class or series to be owned by the interested stockholder; or
 
  
 
 · 
 
 
 
the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.
 
In general, Section 203 defines an “interested stockholder” as an entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by the entity or person. Upon its acquisition of our common stock in 2004, Axonyx and its affiliates (including certain of the members of our board of directors) became “interested stockholders” pursuant to Section 203.

INDEMNIFICATION FOR SECURITIES ACT LIABILITIES
 
The Delaware General Corporate Law and the terms of indemnity agreements entered into by us provide for indemnification of our directors and certain officers for liabilities and expenses that they may incur in such capacities. In general, our directors and certain officers are indemnified with respect to actions taken in good faith and in a manner such person believed to be in our best interests, and with respect to any criminal action or proceedings, actions that such person has no reasonable cause to believe were unlawful. Furthermore, the personal liability of our directors is limited as provided in our Certificate of Incorporation.

84
 

We maintain directors and officers liability insurance with an aggregate coverage limit of $4,000,000.
 
Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended (the “Securities Act”) may be permitted to directors, officers or persons controlling us pursuant to the foregoing provisions, we have been advised that in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Act and is therefore unenforceable.

The validity of the shares of common stock being offered was passed upon for us by Richardson & Patel LLP, Los Angeles, California.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors
OXIS International, Inc.
Foster City, California

We have audited the accompanying consolidated balance sheets of OXIS International, Inc. and subsidiaries as of December 31, 2005 and 2004 and the related consolidated statements of operations, stockholders’ equity and cash flows for the years then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the 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. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of OXIS International, Inc., and subsidiaries as of December 31, 2005 and 2004 and the results of its operations, stockholders’ equity and its cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company’s significant and ongoing operating losses raise substantial doubt about its ability to continue as a going concern. Management’s plans regarding the resolution of this issue are also discussed in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 2005 AND 2004


1. The Company and Summary of Significant Accounting Policies

OXIS International, Inc. and its subsidiaries (collectively, “OXIS” or the “Company”) is a clinical diagnostics company engaged in the development of clinical and research assays, diagnostics, nutraceutical and therapeutic products, which include new technologies applicable to conditions and diseases associated with oxidative stress. OXIS derives its revenues primarily from sales of research diagnostic assays to research laboratories during 2005. The Company’s diagnostic products include twenty-five research assays to measure markers of oxidative stress.

In 1965, the corporate predecessor of OXIS, Diagnostic Data, Inc. was incorporated in the State of California. Diagnostic Data changed its incorporation to the State of Delaware in 1972; and changed its name to DDI Pharmaceuticals, Inc. in 1985. In 1994, DDI Pharmaceuticals merged with International BioClinical, Inc. and Bioxytech S.A. and changed its name to OXIS International, Inc. The Company’s principal executive offices were relocated to Foster City, California from Portland, Oregon on February 15, 2006.

On September 19, 2005, the Company entered into a stock purchase agreement with BioCheck, Inc. (“BioCheck”) and certain stockholders of BioCheck to purchase all of the common stock of BioCheck for $6.0 million in cash. On December 6, 2005, the Company purchased 51% of the common stock of BioCheck from each of the stockholders of BioCheck on a pro rata basis, for $3,060,000 in cash. The consolidated statement of operations for the year ended December 31, 2005 includes the results of operations of BioCheck from December 6, 2005, the date of acquisition, and the consolidated balance sheet at December 31, 2005 includes the assets and liabilities of BioCheck. With the BioCheck acquisition, the Company anticipates that over fifty percent of its revenues will be derived from sales of clinical diagnostic assays in 2006.

The Company incurred net losses of $3.1 million in 2005 and $2.7 million in 2004. BioCheck generated a profit of $0.2 million in 2005. This amount of profit would not be enough to offset the Company’s current losses. The 2005 loss includes an expense of $1.5 million for purchased in-process research and development that will not reoccur in 2006. However, the Company is seeking debt financing that may have related warrants. Such a financing may result in large non-cash financing charges that could delay profitability. The Company’s plan is to increase revenues to generate sufficient gross profit in excess of selling, general and administrative, and research and development expenses in order to achieve profitability. However, the Company can not assure you that it will accomplish this task and there are many factors that may prevent the Company from reaching its goal of profitability.

As shown in the accompanying financial statements, the Company has incurred an accumulated deficit of $65,379,000 through December 31, 2005. On a consolidated basis, the Company had cash and cash equivalents of $614,000 at December 31, 2005 of which $282,000 was held by BioCheck. Since BioCheck has been and is expected to continue to be cash flow positive, management believes that its cash will be sufficient to sustain its operating activities. The cash held by the OXIS parent company of $332,000 at December 31, 2005 is not sufficient to sustain its operations through the first quarter of 2006 without additional financings. During March 2006, the Company received $200,000 from its president and chief executive officer in exchange for a promissory note. An estimated $1.0 million is believed necessary to continue operations through the next fiscal year and approximately $3.0 million is required to purchase the remaining 49% of BioCheck. The Company is seeking additional loan and equity financings to obtain sufficient funds to sustain operations, implement its marketing campaign and purchase the remaining 49% of BioCheck. The Company plans to increase revenues by its marketing campaign and the introduction of new products. However, we cannot assure you that we will successfully obtain debt or equity financing, if any, sufficient to finance our goals or that we will increase product related revenues as such events are subject to factors beyond our control. The financial statements do not include any adjustments relating to the recoverability and classification of recorded assets, or the amounts and classification of liabilities that might be necessary in the event the Company cannot continue in existence.

YEARS ENDED DECEMBER 31, 2005 AND 2004
 
Basis of Consolidation and Comprehensive Income

The accompanying consolidated financial statements include the accounts of OXIS International, Inc. and its subsidiaries. All intercompany balances and transactions have been eliminated. The Company’s financial statements are prepared using the accrual method of accounting. On December 6, 2005, the Company purchased 51% of the common stock of BioCheck. The consolidated statement of operations for the year ended December 31, 2005 includes the results of operations of BioCheck from December 6, 2005, the date of acquisition, and the consolidated balance sheet at December 31, 2005 includes the assets and liabilities of BioCheck. The foreign subsidiaries’ assets and liabilities are translated at the exchange rates at the end of the year, and their statements of operations are translated at the average exchange rates during each year. Gains and losses resulting from foreign currency translation are recorded as other comprehensive income or loss and accumulated as a separate component of stockholders’ equity. There were no items of other comprehensive income or loss in 2005 and, therefore, comprehensive loss is the same as net loss for 2005.

Segment Reporting

The Company currently manages its business on the basis of one reportable segment. The Company’s management uses consolidated results of the Company’s operations to make decisions affecting product development, manufacturing, and marketing. The Company determines and discloses its segments in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 131, “Disclosures about Segments of an Enterprise and Related Information” (hereinafter “SFAS No. 131”) which uses a “management” approach for determining segments. The management approach designates the internal organization that is used by management for making operating decisions and assessing performance as the source of the Company’s reportable segments. SFAS No. 131 also requires disclosures about products or services, geographic areas, and major customers (see Note 13). The Company’s management reporting structure provided for two segments prior to 2004 and the first quarter of 2004 and accordingly, separate segment information was presented.

Use of Estimates

The financial statements and notes are representations of the Company’s management, which is responsible for their integrity and objectivity. These accounting policies conform to accounting principles generally accepted in the United States of America, and have been consistently applied in the preparation of the financial statements. The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities revenues and expenses and disclosures of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents.

Concentrations of Credit Risk

Revenues from sales to one of the Company’s distributors located outside of the United States were 15% and 11% of total revenues during 2005 and 2004, respectively. Approximately 38% of the Company’s revenues were attributed to seven customers in 2005 and 40% of the Company’s sales revenues were attributed to six customers in 2004. In addition, the Company signed an exclusive license agreement during the third quarter of 2004, resulting in revenues of $450,000, or 19% of total revenues for 2004 (see Note 12).

F-8
 

OXIS INTERNATIONAL, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
YEARS ENDED DECEMBER 31, 2005 AND 2004
 
The Company’s cash and cash equivalents, marketable securities and accounts receivable are monitored for exposure to concentrations of credit risk. Cash equivalents and marketable securities consist of high quality credit instruments and management regularly monitors their composition and maturities. The Company maintains cash in money market accounts and a bank certificate of deposit. Management monitors the amount of credit exposure related to accounts receivable on an ongoing basis and generally requires no collateral from customers. The Company maintains allowances for estimated probable losses, when applicable.

Derivative instruments

In February 2006, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 155, “Accounting for Certain Hybrid Financial Instruments, an Amendment of FASB Standards No. 133 and 140” ( “SFAS No. 155”). This statement established the accounting for certain derivatives embedded in other instruments. It simplifies accounting for certain hybrid financial instruments by permitting fair value remeasurement for any hybrid instrument that contains an embedded derivative that otherwise would require bifurcation under SFAS No. 133 as well as eliminating a restriction on the passive derivative instruments that a qualifying special-purpose entity (“SPE”) may hold SFAS No. 140 “Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities” (“SFAS No. 140”). This statement allows a public entity to irrevocably elect to initially and subsequently measure a hybrid instrument that would be required to be separated into a host contract and derivative in its entirety at fair value (with changes in fair value recognized in earnings) so long as that instrument is not designated as a hedging instrument pursuant to the statement. SFAS No. 140 previously prohibited a qualifying special-purpose entity from holding a derivative financial instrument that pertains to a beneficial interest other than another derivative financial instrument. This statement is effective for fiscal years beginning after September 15, 2006, with early adoption permitted as of the beginning of an entity’s fiscal year. Management believes the adoption of this statement will have no impact on the Company’s financial condition or results of operations.

 
If certain conditions are met, a derivative may be specifically designated as a hedge, the objective of which is to match the timing of gain or loss recognition on the hedging derivative with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk or the earnings effect of the hedged forecasted transaction. For a derivative not designated as a hedging instrument, the gain or loss is recognized in income in the period of change. The Company has not entered into derivatives contracts to hedge existing risks or for speculative purposes. During 2005 and 2004, the Company has not engaged in any transactions that would be considered derivative instruments.

Fair value of Financial Instruments

The carrying amount of cash and cash equivalents, restricted cash, accounts receivable, inventory, accounts payable and accrued expenses approximate fair value because of the short-term nature of these instruments. The fair value of debt is based upon current interest rates for debt instruments with comparable maturities and characteristics and approximates the carrying amount.

Accounts receivable

The Company carries its accounts receivable at cost less an allowance for doubtful accounts. On a periodic basis, the Company evaluates its accounts receivable and establishes an allowance for doubtful accounts, based on a history of past write-offs and collections and current credit conditions. The following table summarizes the activity for the Company’s allowance for doubtful accounts:

Inventories

Inventories are stated at the lower of cost or market. Cost has been determined by using the first-in, first-out method. The Company periodically reviews its reserves for slow moving and obsolete inventory and believes that such reserves are adequate at December 31, 2005 and 2004.

In November 2004, the FASB issued SFAS No. 151, “Inventory Costs— an amendment of ARB No. 43, Chapter 4”. This statement amends the guidance in ARB No. 43, Chapter 4, “Inventory Pricing,” to clarify the accounting for abnormal amounts of idle facility expense, freight, handling costs, and wasted material (spoilage). Paragraph 5 of ARB 43, Chapter 4, previously stated that “. . . under some circumstances, items such as idle facility expense, excessive spoilage, double freight, and rehandling costs may be so abnormal as to require treatment as current period charges. . . .” This statement requires that those items be recognized as current-period charges regardless of whether they meet the criterion of “so abnormal.” In addition, this statement requires that allocation of fixed production overheads to the costs of conversion be based on the normal capacity of the production facilities. This statement is effective for inventory costs incurred during fiscal years beginning after June 15, 2005. Management does not believe the adoption of this statement will have any immediate material impact on the Company.

Restricted Cash

The Company invested $3,060,000 of cash into a 30-day certificate of deposit at KeyBank, N.A. (“KeyBank”) and entered into $3,060,000 non-revolving one-year loan agreement with KeyBank on December 2, 2005 for the purpose of completing the initial closing of the BioCheck acquisition. The Company granted a security interest in its $3,060,000 certificate of deposit to KeyBank under the loan agreement. Consequently, the certificate of deposit is classified as restricted cash on the consolidated balance sheet at December 31, 2005 as the cash is restricted as to use.
 
Property, Plant and Equipment

Property, plant and equipment is stated at cost. Depreciation is computed on a straight-line basis over the estimated useful lives of the assets, which are 3 to 10 years for machinery and equipment, the shorter of the lease term or estimated economic life for leasehold improvements. For the Company’s BioCheck subsidiary, depreciation has been computed on a double-declining basis over the estimated useful lives of the assets, which generally has been 7 years for machinery and equipment, and 39 years for leasehold improvements. BioCheck will conform to the Company’s straight-line depreciation method for assets purchased after 2005.

Patents

Acquired patents are capitalized at their acquisition cost or fair value. The legal costs, patent registration fees and models and drawings required for filing patent applications are capitalized if they relate to commercially viable technologies. Commercially viable technologies are those technologies that are projected to generate future positive cash flows in the near term. Legal costs associated with patent applications that are not determined to be commercially viable are expensed as incurred. All research and development costs incurred in developing the patentable idea are expensed as incurred. Legal fees from the costs incurred in successful defense to the extent of an evident increase in the value of the patents are capitalized.

OXIS INTERNATIONAL, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
YEARS ENDED DECEMBER 31, 2005 AND 2004

Capitalized cost for pending patents are amortized on a straight-line basis over the remaining twenty year legal life of each patent after the costs have been incurred. Once each patent is issued, capitalized costs are amortized on a straight-line basis over the shorter of the patent’s remaining statutory life, estimated economic life or ten years.

Goodwill

In connection with the acquisition of BioCheck (see Note 2), the Company recorded goodwill equal to the excess of the fair value of the consideration given over the estimated fair value of the assets and liabilities received. The goodwill was primarily attributed to the reputation of the principals and the cGMP/ISO 9000 compliant manufacturing facilities in Foster City, California.

Impairment of Long Lived Assets

The Company’s long-lived assets include capitalized patents, goodwill, property and equipment related to the Company’s manufacturing facilities in California and Oregon. The Company evaluates its long-lived assets for impairment in accordance with SFAS (“SFAS”) No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. If any of the Company’s long-lived assets are considered to be impaired, the amount of impairment to be recognized is equal to the excess of the carrying amount of the assets over the fair value of the assets (see Notes 4, 5 and 6).

Financial Accounting Standards No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (“SFAS No. 144”) establishes a single accounting model for long-lived assets to be disposed of by sale, including discontinued operations. SFAS No. 144 requires that these long-lived assets be measured at the lower of carrying amount or fair value less cost to sell, whether reported in continuing operations or discontinued operations. The Company relocated manufacturing and administrative functions from Portland, Oregon to Foster City, California during the first quarter of 2006 and closed the Portland, Oregon facility. Certain assets will be disposed of or sold during 2006. Since the Company has not yet determined those individual assets for sale or disposition at December 31, 2005, no assets have been reclassified to property, plant and equipment held for sale and disposition. The Company believes that no adjustments are needed to the carrying value of these assets at December 31, 2005 and 2004.

In connection with the acquisition of BioCheck (see Note 2), the Company recorded goodwill equal to the excess of the fair value of the consideration given over the estimated fair value of the assets and liabilities received. The Company adopted SFAS No. 142, “Goodwill and Other Intangible Assets” (“SFAS No. 142”) that discontinued the amortization of goodwill and requires the testing of goodwill for impairment annually, or sooner, if indicators of potential impairment exist, based upon a fair value approach. In accordance with SFAS No. 142, OXIS performed an impairment test of goodwill as of December 6, 2005 and found no evidence of impairment. The Company evaluated several factors to determine the fair value of the BioCheck business including projected cash flows from product sales and cash receipts expected from those sales.

Revenue Recognition

The Company manufactures, or has manufactured on a contract basis, research and diagnostic assays and fine chemicals, which are its primary products sold to customers. Revenue from the sale of the Company’s products, including shipping fees, if any, is recognized when title to the products is transferred to the customer which usually occurs upon shipment or delivery, depending upon the terms of the sales order and when collectibility is reasonably assured. Revenue from sales to distributors of the Company’s products is recognized, net of allowances, upon delivery of product to the distributors. According to the terms of individual distributor contracts, a distributor may return product up to a maximum amount and under certain conditions contained in its contract. Allowances are calculated based upon historical data, current economic conditions and the underlying contractual terms.

F-11
 

OXIS INTERNATIONAL, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
YEARS ENDED DECEMBER 31, 2005 AND 2004

The Company recognizes license fee revenue for licenses to its intellectual property when earned under the terms of the agreements. Generally, revenue is recognized upon transfer of the license unless the Company has continuing obligations for which fair value cannot be established, in which case the revenue is recognized over the period of the obligation. The Company considers all arrangements with payment terms extending beyond twelve months not to be fixed or determinable. In certain licensing arrangements there is provision for a variable fee as well as a non-refundable minimum amount. In such arrangements, the amount of the non-refundable minimum guarantee is recognized upon transfer of the license and collectibility is reasonably assured or over the period of the obligation, as applicable, and the amount of the variable fee is recognized as revenue when it is fixed and determinable. The Company recognizes royalty revenue based on reported sales by third party licensees of products containing its materials, software and intellectual property. Non-refundable royalties, for which there are no further performance obligations, are recognized when due under the terms of the agreements.

Research and Development

Research and development costs are expensed as incurred and reported as research and development expense.

Advertising and promotional fees

Advertising expenses consist primarily of costs incurred in the design, development, and printing of Company literature and marketing materials. The Company expenses all advertising expenditures as incurred. The Company’s advertising expenses were $51,000 and $1,000 for the years ended December 31, 2005 and 2004, respectively.

Stock-Based Compensation

The Company has historically accounted for stock options granted to employees and directors and other stock-based employee compensation plans using the intrinsic value method of accounting in accordance with Accounting Principles Board Opinion No. 25 (“APB 25”), “Accounting for Stock Issued to Employees” and related interpretations. As such, the Company recognized compensation expense for stock options only if the quoted market value of the Company’s common stock exceeded the exercise price of the option on the grant date. Any compensation expense realized using this intrinsic value method is being amortized over the vesting period of the option.

In December 2004, the FASB issued a revision to SFAS No. 123 (revised 2004), “Share-Based Payments” ( “SFAS No. 123R”). This statement replaces SFAS No. 123, “Accounting for Stock-Based Compensation” (“SFAS 123”), and supersedes APB Opinion No. 25, “Accounting for Stock Issued to Employees”. SFAS No. 123R establishes standards for the accounting for share-based payment transactions in which an entity exchanges its equity instruments for goods or services. It also addresses transactions in which an entity incurs liabilities in exchange for goods or services that are based on the fair value of the entity’s equity instruments or that may be settled by the issuance of those equity instruments. This statement covers a wide range of share-based compensation arrangements including share options, restricted share plans, performance-based award, share appreciation rights and employee share purchase plans. SFAS No. 123R requires a public entity to measure the cost of employee services received in exchange for an award of equity instruments based on the fair value of the award on the grant date ( with limited exceptions). That cost will be recognized in the entity’s financial statements over the period during which the employee is required to provide services in exchange for the award. Management is evaluating the effects of SFAS 123R and believes its implementation effect on the Company’s financial statements will be similar as disclosed below. The following table presents the effect on net loss and net loss per share if the Company had applied the fair value recognition provisions of SFAS 123 to stock-based awards to employees:

The fair values of employee stock options are estimated for the calculation of the pro forma adjustments in the above table at the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions during 2005 and 2004: expected volatility of 170% and 73%, respectively; average risk-free interest rate of 4.22% and 4.25%, respectively; initial expected life of six years and ten years, respectively; and no expected dividend yield and amortized over the vesting period of typically one to four years.

Stock options issued to non-employees as consideration for services provided to the Company have been accounted for under the fair value method in accordance with SFAS 123 and Emerging Issues Task Force No. 96-18, “Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services,” which requires that compensation expense be recognized for all such options.
 
Income Taxes

The Company accounts for income taxes using the asset and liability approach whereby deferred income tax assets and liabilities are recognized for the estimated future tax effects, based on current enacted tax laws, of temporary differences between financial and tax reporting for current and prior periods. Deferred tax assets are reduced, if necessary, by a valuation allowance if the corresponding future tax benefits may not be realized (see Note 11).

Net Loss Per Share

Basic net loss per share is computed by dividing the net loss for the period by the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing the net loss for the period by the weighted average number of common shares outstanding during the period, plus the potential dilutive effect of common shares issuable upon exercise or conversion of outstanding stock options and warrants during the period. The weighted average number of potentially dilutive common shares are 1,217,435 in 2005 and 1,981,598 in 2004. These shares were excluded from diluted loss per share because of their anti-dilutive effect.

Recent Accounting Pronouncements

In March 2006, the FASB issued SFAS No. 156, “Accounting for Servicing of Financial Assets—an amendment of FASB Statement No. 140.” This statement requires an entity to recognize a servicing asset or servicing liability each time it undertakes an obligation to service a financial asset by entering into a servicing contract in any of the following situations: a transfer of the servicer’s financial assets that meets the requirements for sale accounting; a transfer of the servicer’s financial assets to a qualifying special-purpose entity in a guaranteed mortgage securitization in which the transferor retains all of the resulting securities and classifies them as either available-for-sale securities or trading securities; or an acquisition or assumption of an obligation to service a financial asset that does not relate to financial assets of the servicer or its consolidated affiliates. The statement also requires all separately recognized servicing assets and servicing liabilities to be initially measured at fair value, if practicable and permits an entity to choose either the amortization or fair value method for subsequent measurement of each class of servicing assets and liabilities. The statement further permits, at its initial adoption, a one-time reclassification of available for sale securities to trading securities by entities with recognized servicing rights, without calling into question the treatment of other available for sale securities under Statement 115, provided that the available for sale securities are identified in some manner as offsetting the entity’s exposure to changes in fair value of servicing assets or servicing liabilities that a servicer elects to subsequently measure at fair value and requires separate presentation of servicing assets and servicing liabilities subsequently measured at fair value in the statement of financial position and additional disclosures for all separately recognized servicing assets and servicing liabilities. This statement is effective for fiscal years beginning after September 15, 2006, with early adoption permitted as of the beginning of an entity’s fiscal year. Management believes the adoption of this statement will have no impact on the Company’s financial condition or results of operations.

In May 2005, the FASB issued SFAS No. 154, “Accounting Changes and Error Corrections,” (hereinafter “SFAS No. 154”) which replaces Accounting Principles Board Opinion No. 20, “Accounting Changes”, and SFAS No. 3, “Reporting Accounting Changes in Interim Financial Statements - An Amendment of APB Opinion No. 28”. SFAS No. 154 provides guidance on accounting for and reporting changes in accounting principle and error corrections. SFAS No. 154 requires that changes in accounting principle be applied retrospectively to prior period financial statements and is effective for fiscal years beginning after December 15, 2005. The Company does not expect SFAS No. 154 to have a material impact on its consolidated financial position, results of operations, or cash flows.

In December 2004, the FASB issued SFAS No. 153. This statement addresses the measurement of exchanges of nonmonetary assets. The guidance in APB Opinion No. 29, “Accounting for Nonmonetary Transactions,” is based on the principle that exchanges of nonmonetary assets should be measured based on the fair value of the assets exchanged. The guidance in that opinion, however, included certain exceptions to that principle. This statement amends Opinion 29 to eliminate the exception for nonmonetary exchanges of similar productive assets and replaces it with a general exception for exchanges of nonmonetary assets that do not have commercial substance. A nonmonetary exchange has commercial substance if the future cash flows of the entity are expected to change significantly as a result of the exchange. This statement is effective for financial statements for fiscal years beginning after June 15, 2005. Earlier application is permitted for nonmonetary asset exchanges incurred during fiscal years beginning after the date of this statement is issued. Management believes the adoption of this statement will have no impact on the financial statements of the Company.

In December 2004, the FASB issued SFAS No. 152, which amends FASB statement No. 66, “Accounting for Sales of Real Estate,” to reference the financial accounting and reporting guidance for real estate time-sharing transactions that is provided in AICPA Statement of Position (SOP) 04-2, “Accounting for Real Estate Time-Sharing Transactions.” This statement also amends FASB Statement No. 67, “Accounting for Costs and Initial Rental Operations of Real Estate Projects,” to state that the guidance for (a) incidental operations and (b) costs incurred to sell real estate projects does not apply to real estate time-sharing transactions. The accounting for those operations and costs is subject to the guidance in SOP 04-2. This statement is effective for financial statements for fiscal years beginning after June 15, 2005. Management believes the adoption of this statement will have no impact on the financial statements of the Company.

Reclassifications

Certain 2004 amounts have been reclassified to conform to the 2005 presentation. This reclassification has resulted in no changes to the Company’s accumulated deficit or net losses presented.

2. Acquisition of BioCheck

On September 19, 2005, the Company entered into a stock purchase agreement with BioCheck and certain stockholders of BioCheck to purchase all of the common stock of BioCheck for $6.0 million in cash. BioCheck was a privately held California corporation engaged in the development of immunoassays, with a number of clinical diagnostic tests that have been approved by the United States Food and Drug Administration. On December 6, 2005, the Company purchased 51% of the common stock of BioCheck from each of the stockholders of BioCheck on a pro rata basis, for $3,060,000 in cash. This acquisition was accounted for by the purchase method of accounting according to SFAS No. 141, “Business Combinations.”

Pursuant to the stock purchase agreement, OXIS will use its reasonable best efforts to consummate a follow-on financing transaction to raise additional capital with which to purchase the remaining outstanding shares of BioCheck in one or more additional closings. The purchase price for any BioCheck shares purchased after the initial closing will be increased by an additional 8% per annum from December 6, 2005. If OXIS has not purchased all of the outstanding shares of BioCheck within twelve months of December 6, 2005, the earnings before interest, taxes, depreciation and amortization expenses, if any, of BioCheck, will be used to repurchase the remaining outstanding BioCheck shares at one or more additional closings. The purchase of the remaining outstanding shares of BioCheck acquisition will be accounted for the same as the initial purchase of 51% of BioCheck using the purchase method of accounting according to SFAS No. 141. The additional purchase price will be allocated over the purchased assets of BioCheck and the consolidated statement of operations will continue to include the results of operations of BioCheck reduced by the minority interest, if any, in BioCheck. The Company may obtain additional independent valuations of BioCheck’s assets related to the acquisition of the remaining 49% of BioCheck and additional acquisition costs may be incurred. Such information and costs may affect the disclosures as presented herein.

The primary reasons for the acquisition was BioCheck’s products under development, cGMP/ISO 9000 facilities and sales volume in growing markets. In addition, BioCheck’s management has a core competency and a proven scientific and business development track record in developing and manufacturing of high-quality immunoassay products. Senior management has several decades of combined research and development, clinical and operational experience in the biotechnology and pharmaceutical industries.

The purchase price of $3,337,000 was based on cash paid to BioCheck’s stockholders of $3,060,000, legal expense of $155,000 and a finder’s fee of $122,000. The consolidated statement of operations for the year ended December 31, 2005 includes the results of operations of BioCheck from December 6, 2005, the date of acquisition.

The allocation of the cost of the acquisition at December 6, 2005 is as follows:

Purchased in-process research and development was expensed at the date of acquisition and presented on the statement of operations as purchased in-process research and development. It represents the value of purchased in-process research and development projects that had not reached technological feasibility at the date of acquisition. These projects relate to the development of specific immunoassays including the Id-protein based diagnostic/prognostic product and HMGA2 gene breast cancer marker. This technology can only be used for detection of the target protein. No alternative future uses or markets were identified for these projects because of the applicability to specific disease markers.

Patents were capitalized and will be amortized according to the Company’s patent amortization policy over 20 years for pending patents from the date of filing and 10 years after the patents are issued.

The goodwill was attributed to the reputation of the principals and the cGMP/ISO 9000 compliant manufacturing facility in Foster City, California. Goodwill is expected to be deductible for tax purposes. Such amounts were tested for impairment on the date of acquisition resulting in no impairment charge and will be tested at least annually thereafter.

The Company relocated its manufacturing and administrative functions from Portland, Oregon to Foster City, California during the first quarter of 2006 and closed its Portland, Oregon facility. Certain assets will be disposed of or sold during 2006. Since the Company has not yet determined those individual assets that will be sold or disposed of at December 31, 2005, no assets have been reclassified to property, plant and equipment held for sale and disposition. The Company believes that no adjustments are needed to the carrying value of these assets at December 31, 2005. Depreciation expense was $28,000 and $21,000 during 2005 and 2004, respectively.

Periodically, the Company reviews its patent portfolio and has determined that certain patent applications no longer possessed commercial viability or were abandoned since they were inconsistent with the Company’s business development strategy. As a result, research and development expense included charges of $105,000 in 2005 for the write-off of capitalized patent costs. Research and development expense includes patent amortization charges of $126,000 and $77,000 in 2005 and 2004, respectively.

In connection with the acquisition of BioCheck (see Note 2), the Company recorded goodwill equal to the excess of the fair value of the consideration given over the estimated fair value of the assets and liabilities received. The goodwill was primarily attributed to the reputation of BioCheck’s CEO and the cGMP/ISO 9000 compliant manufacturing facilities in Foster City, California. Strategic investments are investments by BioCheck in two private start-up companies. One of those companies has not yet commenced operations. The Company is aware of private sales in the other company’s stock that exceeded the per share purchase price of its investment. Lease deposits are cash deposits held as security for facility leases in Foster City, California.

On December 2, 2005, the Company entered into non-revolving one-year loan agreement with KeyBank, N.A. (“KeyBank”) in the amount of $3,060,000, for the purpose of completing the initial closing of the BioCheck acquisition. The Company has granted a security interest in its $3,060,000 certificate of deposit at KeyBank under the loan agreement. The loan bears interest at an annual rate that is 2.0% greater than the interest rate on the certificate of deposit. This loan was repaid during February 2006 and a new loan agreement similar in terms to this loan and a certificate of deposit were entered into at Bridge Bank.

 
On June 1, 2004, the Company received $1,200,000 in exchange for a note (the “Note”) and entered into a loan agreement with its majority stockholder, Axonyx, Inc. The Note, with interest at 7%, was secured by the Company’s intellectual property and became immediately due and payable upon the Company’s completion of a private placement of 12,264,158 shares of its common stock for $6,500,000. The Company paid to Axonyx the full amount of the note and accrued interest on January 6, 2005.

The Company originally issued a promissory note payable for $160,000 on April 9, 1997 to Finovelec, a French société anonyme that was subsequently transferred to Equitis Entreprise, a French société par actions simplifiée (“Equitis”). The unsecured note payable bore interest at 8%, was due in May 1997 and was, therefore, delinquent. On May 23, 2005, Equitis converted the note and accrued interest of $84,000 into 459,355 shares of common stock.

The Company received $570,000 in loans and issued 12 month promissory notes convertible into 1,425,000 shares of the Company’s common stock on January 14, 2004. The Company also issued five-year warrants to the lenders to purchase 712,500 shares of common stock at an exercise price of $0.50 per share. The Company received notice on December 30, 2004, that all lenders had irrevocably converted their promissory notes and accrued interest of $39,000 into common stock. As a result, the Company issued 1,520,932 shares of common stock to the note holders. As an incentive for the lenders to convert their notes to common stock, the Company issued additional five-year warrants to purchase 760,469 shares of common stock at an exercise price of $1.00 per share. During 2004, financing fees included non-cash financing charges of $411,000 related to the conversion feature of the notes, $159,000 related to the initial warrants and $202,000 related to the incentive warrants. The fair values of the conversion feature of the notes and warrants were determined using the Black-Scholes pricing model.

The Company leases a facility under an operating lease in Portland, Oregon and incurred facility rental expenses of $138,000 and $134,000 during 2005 and 2004, respectively. The Company’s subsidiary, BioCheck, leases facilities under operating leases in Foster City, California included in the table above. During 2004, BioCheck entered into a sublease of an unused Foster City, California facility to the end of the lease term in 2008 that reduced the Company’s operating lease commitments.

The Company has agreements with various consultants who provide operating, administrative and marketing services to the Company. Generally these agreements may be terminated by the Company within 30 days. Non-cancelable minimum payments related to these agreements were $69,000 at December 31, 2005.

At December 31, 2005, the Company has a commitment to purchase Ergothioneine manufactured by Cambridge Major Labs for $179,000 and has a contract with them to purchase additional Ergothioneine as needed.

On December 6, 2005, the Company committed itself to a plan to cease operations in Portland, Oregon and relocate operations to Foster City, California. As part of the relocation of operations, the Company offered all affected regular full-time employees whose employment was terminated severance benefits estimated in total to be $119,000 that were included in accrued expenses at December 31, 2005. The Company estimates that relocating operations from Portland, Oregon to Foster City, California will cost approximately $100,000. No amounts have been accrued in 2005 related to relocating operations.

On September 19, 2005, the Company entered into a stock purchase agreement with BioCheck, and its stockholders to purchase all of its common stock for $6.0 million in cash. On December 6, 2005, the Company purchased 51% of the common stock of BioCheck. Pursuant to the stock purchase agreement, the Company will use its reasonable best efforts to consummate a follow-on financing transaction to raise additional capital with which to purchase the remaining outstanding shares of BioCheck in one or more additional closings. The purchase price will be increased by an additional 8% per annum from December 6, 2005. If the Company has not purchased all of the outstanding shares of BioCheck within twelve months of December 6, 2005, the earnings before interest, taxes, depreciation and amortization expenses, if any, of BioCheck, will be used to repurchase the remaining outstanding BioCheck shares at one or more additional closings.

In 1995, the Company consummated the acquisition of Therox Pharmaceuticals, Inc. (“Therox”) wherein Therox was merged with and into a wholly owned subsidiary of the Company. In addition to the issuance of its common stock to Therox stockholders, the Company agreed to make payments of up to $2,000,000 to the Therox stockholders based on the successful commercialization of Therox technologies. As of December 31, 2005, no additional payments have been made. The Company has not recorded a liability associated with this agreement because the Company does not believe that it has successfully commercialized any of the acquired Therox technologies.

In 1997, the Company completed an offering of its common stock to European investors, and listed the resulting shares on the Nouveau Marché in France. The Company was notified that a Paris lower court (Tribunal de grande instance de Paris) on November 12, 2003, issued an order (the “Order”) requiring the Company to file its 2002 Document de Reference (“2002 Reference Document”) as required under French law and the regulations of the Autorité des Marchés Financiers (the “AMF”), the French regulatory agency overseeing the Nouveau Marché, within eight days of the court’s Order (“filing deadline”) and if the Company has not filed with the AMF its 2002 Reference Document by the filing deadline, to pay a fine of 1,500 Euros for each day until it files its 2002 Reference Document with the AMF. Following the issuance of the Order, the Company filed its 2002 Reference Document with the AMF and received written confirmation that its 2002 Reference Document has been registered and appealed the Order to the extent that it imposed fines on the Company. The Company has since dismissed its appeal of the Order, and during the first quarter of 2004 paid approximately $11,600 in settlement of any obligation to pay fines under the Order.

The AMF also engaged in a separate investigation relating to the Company’s failing to file financial and other disclosure information as required under French law from 1999 through 2002 (the “Investigation”). At a hearing before the Disciplinary Commission of the AMF on June 17, 2004 the Disciplinary Commission considered a report of the AMF investigator recommending that the Disciplinary Commission impose a fine of not less than 100,000 Euros. Following the hearing, the Disciplinary Commission ordered the Company to pay a fine of 50,000 Euros (approximately $62,000) with respect to the Company’s failure to file financial and other disclosure information as required under French law from 1999 through 2002. The Company did not appeal this order and the fine has been paid. During 2004, the Company recorded expenses of approximately $183,000 related to the defense and settlement of this investigation, including foreign legal expenses of $121,000 and fines imposed by the AMF of $62,000. These charges were recorded as foreign legal proceedings in the consolidated statement of operations for 2004.

The Company and its subsidiaries are also parties to various other claims in the ordinary course of business. The Company does not believe that there will be any material impact on the Company’s financial position, results of operations or cash flows as a result of these claims.

9. Stockholders’ Equity  

Common Stock

Each share of common stock is entitled to one vote at the Company’s annual meeting of stockholders.

The Company’s president and chief executive officer purchased 600,000 shares of common stock for $240,000, pursuant to the terms of an employment agreement on February 28, 2005 at the closing price of the Company’s common stock on that date. During April 2005, 459,355 shares of common stock were issued to a note holder for cancellation of a note payable and accrued interest. During the third quarter of 2005, 85,678 shares of common stock were issued for the conversion and cancellation of all 428,389 outstanding shares of Series B preferred stock.

In a private placement of the Company’s common stock on December 30, 2004, the Company received $4,250,000 in cash and a receivable of $2,250,000 in exchange for 12,264,158 shares of common stock and warrants to purchase 12,877,366 shares of common stock which were issuable at December 31, 2004. After expenses of $380,000 in 2004 and additional expenses of $302,000 in 2005 for the related registration statement, net proceeds were $5,818,000. The common stock was subsequently issued at $0.53 per share and the receivable was collected during January 2005. The warrants were issued for the purchase of 6,438,685 shares of common stock at an exercise price of $0.66 per share and 6,438,681 shares of common stock at an exercise price of $1.00 per share. Pursuant to a registration rights agreement entered into in relation to the private placement, OXIS filed a registration statement on Form SB-2 covering the shares of common stock and the shares underlying the warrants issued in the private placement (the “Registrable Securities”). Amendment No. 2 to the registration statement on Form SB-2 was declared effective on May 27, 2005. OXIS undertook to use its commercially reasonable best efforts to keep the registration statement continuously effective until the earlier of the date when all the Registrable Securities covered by the registration statement have been sold or may be sold without volume restrictions pursuant to Rule 144(k) or May 27, 2007. Until May 27, 2007, OXIS is obligated to pay each holder of the Registrable Securities cash liquidated damages, equal to 1.5% of the aggregate purchase price paid by such holder for any Registrable Securities then held by such holder if the registration statement covering the Registrable Securities ceases to remain continuously effective for either any period of 15 consecutive calendar days or an aggregate of 20 calendar days during any 12 month period. Such liquidated damages are also payable on the monthly anniversary of either previously mentioned violation if the registration statement is not effective during the period from the date of the violation to the date of its monthly anniversary.

On December 30, 2004, promissory notes in the amount of $570,000 and accrued interest were converted into 1,520,932 shares of common stock. Additional warrants were also issued as described below and in note 7.

The Company accounts for the registration rights agreements as separate freestanding instruments and accounts for the liquidated damages provisions as a derivative liability subject to SFAS No. 133. The estimated fair value of the derivative liability is based on estimates of the probability and costs of cash penalties expected to be incurred and such estimates are revalued at each balance sheet date with changes in value recorded in other income. As of December 31, 2005 and 2004 the Company has estimated the fair values of these derivative liabilities to be nominal and accordingly no liability has been recorded. There were no changes to the estimated fair value during the years ended December 31, 2005 and 2004.

Preferred Stock

During the third quarter of 2005, 85,678 shares of common stock were issued for the conversion and cancellation of all 428,389 outstanding shares of Series B preferred stock that were valued at $4,000. The Series B preferred stock had certain preferential rights with respect to liquidation and dividends. Holders of Series B preferred stock were entitled to noncumulative annual dividends at the rate of $0.115 per share if and when declared by the Company’s board of directors. No dividends to Series B preferred stockholders were issued or unpaid during 2005.

The 96,230 shares of Series C preferred stock are convertible into 27,800 shares of the Company’s common stock at the option of the holders at any time. The conversion ratio is based on the average closing bid price of the common stock for the fifteen consecutive trading days ending on the date immediately preceding the date notice of conversion is given, but cannot be less than .20 or more than .2889 common shares for each Series C preferred share. The conversion ratio may be adjusted under certain circumstances such as stock splits or stock dividends. The Company has the right to automatically convert the Series C preferred stock into common stock if the Company lists its shares of common stock on the Nasdaq National Market and the average closing bid price of the Company’s common stock on the Nasdaq National Market for 15 consecutive trading days exceeds $13.00. Each share of Series C preferred stock is entitled to the number of votes equal to .26 divided by the average closing bid price of the Company’s common stock during the fifteen consecutive trading days immediately prior to the date such shares of Series C preferred stock were purchased. In the event of liquidation, the holders of the Series C preferred stock shall participate on an equal basis with the holders of the common stock (as if the Series C preferred stock had converted into common stock) in any distribution of any of the assets or surplus funds of the Company. The holders of Series C preferred stock are entitled to noncumulative dividends if and when declared by the Company’s board of directors. No dividends to Series C preferred stockholders were issued or unpaid during 2005 and 2004.

The exercise prices per share for options granted were $0.37 in 2005 and ranged from $0.41 to $0.59 in 2004. The options have a 10-year life and vest over periods ranging from one to three years. The fair value of each option was estimated on the date of grant and revalued during the vesting period using the Black-Scholes option-pricing model with the following weighted-average assumptions during 2005 and 2004: expected volatility of 170% and 73%, respectively; average risk-free interest rate of 4.54% and 4.25%; initial expected life of ten years; and no expected dividend yield. Stock compensation expense of $20,000 and $44,000 was recorded in 2005 and 2004, respectively.

In 2004 the Company issued 66,666 shares of common stock valued at fair value of $46,000 to a non-employee consultant in exchange for advisor services.

11. Income Taxes

OXIS and BioCheck will file separate federal and state tax returns for 2005 and will continue to file separate tax returns until OXIS purchases 80% or more of BioCheck. Deferred tax assets and liabilities as contained on the consolidated balance sheet at December 31, 2005 are attributed solely to BioCheck.

Deferred Taxes

Deferred taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, and operating losses and tax credit carryforwards. The significant components of net deferred income tax assets for OXIS excluding BioCheck are:

The prospective tax benefits of the net operating losses of $15,410,000 which existed at the date of acquisition (September 7, 1994) of the French subsidiary will be recorded as a reduction of income tax expense when and if realized. Due to the closure of the French subsidiary’s operations in early 1999, it is unlikely that the Company will ever realize any benefit from the French subsidiary’s operating loss carryforwards.

The prospective tax benefits of the net operating losses of $1,032,000 which existed at the date of acquisition (December 31, 1997) of Innovative Medical Systems Corp. will be recorded as a reduction of the net unamortized balance of property, plant and equipment and intangible assets of $465,000 when and if realized.

SFAS No. 109 requires that the tax benefit of net operating losses, temporary differences and credit carryforwards be recorded as an asset to the extent that management assesses that realization is “more likely than not.” Realization of the future tax benefits is dependent on the Company’s ability to generate sufficient taxable income within the carryforward period. Because of the Company’s history of operating losses, management has provided a valuation allowance equal to its net deferred tax assets. The change in deferred tax assets and the related valuation allowance at December 31, 2005 was $784,000 and primarily related to the net increase in net operating losses and decrease in capitalized research and development expense.

Tax Carryforward

At December 31, 2005, the Company had net operating loss carryforwards of approximately $16,855,000 to reduce United States federal taxable income in future years, and research and development tax credit carryforwards of $411,000 to reduce United States federal taxes in future years. These carryforwards expire as follows:

During 2002, the Company issued preferred stock with voting rights, which would be regarded as a control change under the Internal Revenue Code (IRC). Under IRC Section 382, a control change will limit the utilization of the net operating losses. The Company has not determined the effects of any limitations on the value of net operating losses or any tax credits outstanding prior to the control change. In addition, any future control change may further limit the extent to which the net operating loss carryforwards can be used to offset future taxable income.

12. License Agreement

On September 28, 2004, the Company and HaptoGuard Inc. (“HaptoGuard”) entered into a license agreement relating to the Company’s proprietary compound BXT 51072 and related compounds.   Under the agreement, HaptoGuard has exclusive worldwide rights to develop, manufacture and market BXT-51072 and related compounds from the Company’s library of such antioxidant compounds.  Further, HaptoGuard is responsible for worldwide product development programs with respect to licensed compounds.  HaptoGuard has paid the Company an upfront license fee of $450,000. The agreement provides that HaptoGuard must pay royalties to the Company, as well as additional fees for the achievement of development milestones in excess of $21 million if all milestones are met and regulatory approvals are granted.  The material milestones under the agreement which would generate future payments are as follows: upon initiation of Phase III clinical trials of the products; upon grant by the Food and Drug Administration (FDA) of marketing approval of the products; upon grant by the European Agency for the Evaluation of Medicinal Products (EMEA) for marketing approval of the products; and upon grant of marketing approval of the products for each additional regulatory territory. The royalties paid by the licensee will begin upon the first commercial sale of the licensed products and will vary based upon formulations. The Company has the right to terminate the agreement if the licensee fails to pay the Company any required payments under the agreement or if the licensee fails to comply with certain plan and timeline requirements relating to the development of the licensed compounds and such failure continues for 30 days after the Company has given notice to the licensee of such failure. Either party may terminate the agreement upon 30 days’ written notice upon certain events relating to the other party’s bankruptcy, insolvency, dissolution, winding up or assignment for the benefit of creditors, or upon the other party’s uncured breach of any material provision of the agreement. Otherwise, the agreement terminates when the Company’s underlying patents related to the licensed compounds expire.

During December 2005, the Company granted HaptoGuard a six-month extension to begin Phase II, as defined in the original license agreement in exchange for $100,000.

16. Subsequent Events

On December 6, 2005, the Company committed itself to a plan to cease operations in Portland, Oregon and relocate operations to Foster City, California (the “Relocation”). The Company decided to effect the Relocation after reviewing and evaluating all aspects of the Company’s operations to determine the profitability and viability of continuing in the Portland, Oregon location. During the first quarter of 2006, operations were relocated to California and on February 15, 2006 the Portland, Oregon facility was closed with the termination of employment of all Portland based employees who did not relocate to California. The Company’s subsidiary, BioCheck, has commenced manufacturing and shipping of the Company’s products.

As part of the Relocation, the Company offered all regular full-time employees who were not relocated to Foster City, California benefits under an employee severance package. The Company estimates that the Relocation will cost approximately $100,000 for relocating operations and $119,000 for employee severance benefits. The Company accrued $119,000 in 2005 for employee severance benefit payments, of which $111,000 is expected to be paid during 2006 and $8,000 is expected to be paid during 2007. The Company accrues for these benefits in the period when benefits are communicated to the terminated employees. Typically, terminated employees are not required to provide continued service to receive termination benefits. In general, the Company uses a formula based on the number of years of service to calculate the termination benefits to be provided to affected employees. No amounts have been accrued in 2005 related to relocating operations.

Related to the Relocation, the Company signed a lease agreement (the “Lease Agreement”) with Westcore Peninsula Vintage LLC Company (“Landlord”). Under the terms of the Lease Agreement, the Company has the right to occupy 4,136 square feet of space adjacent to space occupied by its BioCheck subsidiary in Foster City, California. The Lease Agreement starts on April 1, 2006 and ends on March 31, 2009.

The Company’s $3,060,000 loan with KeyBank was repaid during February 2006 and a new one-year loan agreement was entered into at Bridge Bank. The Company has granted a security interest in its $3,060,000 certificate of deposit moved from KeyBank to Bridge Bank. The loan bears interest at 3.0% and the certificate of deposit bears interest at 1.0%.

On March 10, 2006, the Company received $200,000 in exchange for a note with the Company’s president and chief executive officer. The note bears interest at 7%. Interest and principal are due on September 10, 2006 or, at the option of the holder, the date the Company receives net proceeds in the amount of $500,000 or more from a debt or equity financing. In addition, if, at any time on or before the maturity date, the Company enters into an agreement to incur debt, the holder has the right to rollover this note into such debt arrangement, on the same terms and conditions offered to such future lenders. The purpose of this loan was to provide the corporation with short term financing as it seeks longer term financing.

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
September 30, 2006

1. The Company and Summary of Significant Accounting Policies

OXIS International, Inc. with its subsidiaries (collectively, “OXIS” or the “Company”) is a clinical diagnostics company engaged in the development of clinical and research assays, diagnostics, nutraceutical and therapeutic products, which include new technologies applicable to conditions and diseases associated with oxidative stress. OXIS derives its revenues primarily from sales of research diagnostic assays to research laboratories. The Company’s diagnostic products include five cardiac marker assays and 25 research assays to measure markers of oxidative and nitrosative stress.

In 1965, the corporate predecessor of OXIS, Diagnostic Data, Inc., was incorporated in the State of California. Diagnostic Data changed its incorporation to the State of Delaware in 1972 and changed its name to DDI Pharmaceuticals, Inc. in 1985. In 1994, DDI Pharmaceuticals merged with International BioClinical, Inc. and Bioxytech S.A. and changed its name to OXIS International, Inc. The Company’s principal executive offices were relocated to Foster City, California from Portland, Oregon on February 15, 2006.

On September 19, 2005, the Company entered into a stock purchase agreement with BioCheck, Inc. (“BioCheck”) and certain stockholders of BioCheck to purchase all of the common stock of BioCheck for $6.0 million in cash. On December 6, 2005, the Company purchased 51% of the common stock of BioCheck from each of the stockholders of BioCheck on a pro rata basis, for $3,060,000 in cash. BioCheck’s products include over 40 clinical diagnostic assays. The consolidated statements of operations for the three and nine months ended September 30, 2006 include the results of operations of BioCheck and the consolidated balance sheets at December 31, 2005 and September 30, 2006 include the assets and liabilities of BioCheck.

The Company incurred net losses of $1.9 million in the nine months ended September 30, 2006 and $3.1 million in 2005. The Company began expensing stock options effective January 1, 2006 in accordance with the Statement of Financial Accounting Standards No. 123 (revised 2004), “Share-Based Payments” (“SFAS 123R”). The Company extended the terms of existing debt during the third quarter of 2006 and obtained additional debt financings subsequent to September 30, 2006 that included the issuance of warrants. Non-cash financing charges resulting from such financings and the additional non-cash charges related to stock options may delay profitability. The Company’s plan is to increase revenues to generate sufficient gross profit in excess of selling, general and administrative, and research and development expenses in order to achieve profitability. However, the Company cannot provide assurances that it will accomplish this task and there are many factors that may prevent the Company from reaching its goal of profitability.

On a consolidated basis, the Company had cash and cash equivalents of $677,000 at September 30, 2006, of which $656,000 was held by BioCheck. Since BioCheck has been and is expected to continue to be cash flow positive, management believes that its cash will be sufficient to sustain its operating activities.

OXIS INTERNATIONAL, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
September 30, 2006

The OXIS parent company had cash and cash equivalents of $21,000 at September 30, 2006. OXIS cannot access the cash held by its majority-held subsidiary, BioCheck, to pay for the corporate purposes of the OXIS parent company. The Company incurred negative operating cash flows of $0.5 million during the nine months ended September 30, 2006 and $2.1 million during 2005. The OXIS parent company incurred negative operating cash flows of $0.9 million during the nine months ended September 30, 2006. The current rate of cash usage raises substantial doubt about the OXIS parent Company’s ability to continue as a going concern, absent any new sources of significant cash flows. In an effort to mitigate this near-term concern, the Company obtained debt financing in which it received proceeds of $1,350,000 subsequent to September 30, 2006 and is seeking equity financings to obtain sufficient funds to sustain operations and purchase the remaining 49% of BioCheck for approximately $3.0 million. From the aforementioned debt financing, $635,000 was used to repay existing debt, accrued interest and related legal fees. The Company plans to increase revenues by introducing new products. However, the Company cannot provide assurances that it will successfully obtain equity financing, if any, sufficient to finance its goals or that the Company will increase product related revenues. The financial statements do not include any adjustments relating to the recoverability and classification of recorded assets, or the amounts and classification of liabilities that might be necessary in the event the Company cannot continue in existence.

Basis of Presentation

The consolidated financial statements have been prepared by the Company in accordance with the rules and regulations of the Securities and Exchange Commission regarding interim financial information. Accordingly, these financial statements and notes thereto do not include certain disclosures normally associated with financial statements prepared in accordance with accounting principles generally accepted in the United States of America. This interim financial information should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the year ended December 31, 2005 included in the Company’s Annual Report on Form 10-KSB.

The consolidated financial statements include the accounts of OXIS International, Inc. and its subsidiaries. All intercompany balances and transactions have been eliminated. On December 6, 2005, the Company purchased 51% of the common stock of BioCheck. The consolidated statements of operations for the three and nine months ended September 30, 2006 include the results of operations of BioCheck and the consolidated balance sheets include the assets and liabilities of BioCheck at September 30, 2006 and December 31, 2005. BioCheck’s revenues and expenses are not included in the consolidated statements of operations for the three and nine months ended September 30, 2005 because those results of operations were incurred before the December 6, 2005 date of acquisition. In the opinion of the Company’s management, the consolidated financial statements include all adjustments (consisting of only normal recurring adjustments) and disclosures considered necessary for a fair presentation of the results of the interim periods presented. This interim financial information is not necessarily indicative of the results of any future interim periods or for the Company’s full year ending December 31, 2006.

Segment Reporting

The Company operates in one reportable segment.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
September 30, 2006

Restricted Cash

The Company invested $3,060,000 of cash into a 30-day certificate of deposit at KeyBank, N.A. (“KeyBank”) and entered into a $3,060,000 non-revolving one-year loan agreement with KeyBank on December 2, 2005 for the purpose of completing the initial closing of the BioCheck acquisition. The Company granted a security interest in its $3,060,000 certificate of deposit to KeyBank under the loan agreement. The $3,060,000 loan with KeyBank was repaid during February 2006 and a new one-year loan agreement for $3,060,000 was entered into at Bridge Bank, N.A. (“Bridge Bank”). As part of the loan arrangement with Bridge Bank, the Company granted a security interest in a $3,060,000 certificate of deposit transferred from KeyBank to Bridge Bank. The certificate of deposit bears interest at 1.0%. Consequently, these certificates of deposit were classified as restricted cash on the consolidated balance sheets at September 30, 2006 and December 31, 2005 as the cash is restricted as to use.

Share-Based Compensation

The Company has historically accounted for stock options granted to employees and directors and other share-based employee compensation plans using the intrinsic value method of accounting in accordance with Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB 25”) and related interpretations. As such, the Company recognized compensation expense for stock options only if the quoted market value of the Company’s common stock exceeded the exercise price of the option on the grant date. Any compensation expense realized using this intrinsic value method is being amortized over the vesting period of the option.

In December 2004, the Financial Accounting Standards Board (“FASB”) issued SFAS 123R, which requires a public entity to measure the cost of employee services received in exchange for an award of equity instruments based on the fair value of the award on the grant date (with limited exceptions). That cost will be recognized in the entity’s financial statements over the period during which the employee is required to provide services in exchange for the award.

Management implemented SFAS 123R effective January 1, 2006, using the modified prospective application method. Under the modified prospective application method, SFAS 123R applies to new awards and to awards modified, repurchased or cancelled after January 1, 2006. Additionally, compensation costs for the portion of awards for which the requisite service has not been rendered that are outstanding as of January 1, 2006 are recognized as the requisite service is rendered on or after January 1, 2006. The compensation cost for that portion of awards is based on the grant-date fair value of those awards as calculated for proforma disclosures under Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based Compensation” (“SFAS 123”). The compensation cost for awards issued prior to January 1, 2006 attributed to services performed in years after January 1, 2006 uses the attribution method applied prior to January 1, 2006 according to SFAS 123, except that the method of recognizing forfeitures only as they occur was not continued.

OXIS INTERNATIONAL, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
September 30, 2006

The recognition of share-based employee compensation costs during 2006 had no related tax effect since the Company provides a valuation allowance equal to its net deferred tax assets. The adoption of SFAS 123R had no effect on cash flow from operations, cash flow from financing activities and basic and diluted earnings per share. The effect of adoption of SFAS 123R on the results of operations for the nine months ended September 30, 2006 was:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
September 30, 2006

The Company undertook a comprehensive study of options issued from 1994 through 2001 to determine historical patterns of options being exercised and forfeited. The results of this study were used as a source to estimate expected life and forfeiture rates. The new estimated life of 4.45 years was applied only to determine the fair value of awards issued after January 1, 2006. The estimated forfeiture rate of 40% was applied to all awards that vested after January 1, 2006, including awards issued prior to that date, to determine awards expected to be exercised.

The Company issued options to purchase 120,000 shares of the Company’s common stock to employees and directors during the three months ended September 30, 2006. The Company issued no options to employees and directors during the three months ended September 30, 2005. The Company issued options to purchase 400,000 and 615,000 shares of the Company’s common stock to employees and directors during the nine months ended September 30, 2006 and 2005, respectively. The fair values of employee stock options are estimated for the calculation of employee compensation expense in 2006 and the pro forma adjustments in 2005 in the above table at the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions during 2006 and 2005: expected volatility of 90% and 170%, respectively; average risk-free interest rate of 4.59% and 4.00%, respectively; initial expected life of 4.45 years and 6 years, respectively; no expected dividend yield; and amortization over the vesting period of typically one to four years.

Stock options issued to non-employees as consideration for services provided to the Company have been accounted for under the fair value method in accordance with SFAS 123 and Emerging Issues Task Force No. 96-18, “Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services,” which requires that compensation expense be recognized for all such options. The Company issued options to purchase 50,000 shares of the Company’s common stock to non-employees and a warrant to purchase 108,000 shares of the Company’s common stock to a director under a consulting agreement during the nine months ended September 30, 2006. The Company issued no options to non-employees during the nine months ended September 30, 2005.

Net Loss Per Share

Basic net loss per share is computed by dividing the net loss for the period by the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing the net loss for the period by the weighted average number of common shares outstanding during the period, plus the potential dilutive effect of common shares issuable upon exercise or conversion of outstanding stock options and warrants during the period. The weighted average number of potentially dilutive common shares were 318,940 and 769,558 for the three months ended September 30, 2006 and 2005, respectively, and 611,497 and 869,352 for the nine months ended September 30, 2006 and 2005, respectively. These shares were excluded from net diluted loss per share because of their anti-dilutive effect.

Recent Accounting Pronouncements

In February 2006, the FASB issued Statement of Financial Accounting Standards No. 155, “Accounting for Certain Hybrid Financial Instruments, an Amendment of FASB Standards No. 133 and 140” (“SFAS No. 155”). SFAS No. 155 established the accounting for certain derivatives embedded in other instruments. It simplifies accounting for certain hybrid financial instruments by permitting fair value remeasurement for any hybrid instrument that contains an embedded derivative that otherwise would require bifurcation under Statement of Financial Accounting Standards No. 133 “Accounting for Derivative Instruments and Hedging Activities” as well as eliminating a restriction on the passive derivative instruments that a qualifying special-purpose entity (“SPE”) may hold under Statement of Financial Accounting Standards No. 140 “Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities” (“SFAS No. 140”). SFAS No. 155 allows a public entity to irrevocably elect to initially and subsequently measure a hybrid instrument that would be required to be separated into a host contract and derivative in its entirety at fair value (with changes in fair value recognized in earnings) so long as that instrument is not designated as a hedging instrument pursuant to the statement. SFAS No. 140 previously prohibited a qualifying special-purpose entity from holding a derivative financial instrument that pertains to a beneficial interest other than another derivative financial instrument. SFAS No. 155 is effective for fiscal years beginning after September 15, 2006, with early adoption permitted as of the beginning of an entity’s fiscal year. Management believes the adoption of SFAS No. 155 will have no impact on the Company’s financial condition or results of operations.

In March 2006, the FASB issued Statement of Financial Accounting Standards No. 156, “Accounting for Servicing of Financial Assets—an amendment of FASB Statement No. 140” (“SFAS No. 156”). SFAS No. 156 requires an entity to recognize a servicing asset or servicing liability each time it undertakes an obligation to service a financial asset by entering into a servicing contract in any of the following situations: a transfer of the servicer’s financial assets that meets the requirements for sale accounting; a transfer of the servicer’s financial assets to a qualifying special-purpose entity in a guaranteed mortgage securitization in which the transferor retains all of the resulting securities and classifies them as either available-for-sale securities or trading securities; or an acquisition or assumption of an obligation to service a financial asset that does not relate to financial assets of the servicer or its consolidated affiliates. SFAS No. 156 also requires all separately recognized servicing assets and servicing liabilities to be initially measured at fair value, if practicable and permits an entity to choose either the amortization or fair value method for subsequent measurement of each class of servicing assets and liabilities. SFAS No. 156 further permits, at its initial adoption, a one-time reclassification of available for sale securities to trading securities by entities with recognized servicing rights, without calling into question the treatment of other available for sale securities under Statement of Financial Accounting Standards No. 115, “Accounting for Certain Investments in Debt and Equity Securities”, provided that the available for sale securities are identified in some manner as offsetting the entity’s exposure to changes in fair value of servicing assets or servicing liabilities that a servicer elects to subsequently measure at fair value and requires separate presentation of servicing assets and servicing liabilities subsequently measured at fair value in the statement of financial position and additional disclosures for all separately recognized servicing assets and servicing liabilities. SFAS No. 156 is effective for fiscal years beginning after September 15, 2006, with early adoption permitted as of the beginning of an entity’s fiscal year. Management believes the adoption of SFAS No. 156 will have no impact on the Company’s financial condition or results of operations.

In June 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement No. 109” (“FIN 48”), which prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. FIN 48 also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. FIN 48 is effective for fiscal years beginning after December 15, 2006. The Company does not expect the adoption of FIN 48 to have a material impact on its financial reporting, and the Company is currently evaluating the impact, if any, the adoption of FIN 48 will have on its disclosure requirements.

In September 2006, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (“SFAS No. 157”) which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles (“GAAP”), and expands disclosures about fair value measurements. Where applicable, SFAS No. 157 simplifies and codifies related guidance within GAAP and does not require any new fair value measurements. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. Earlier adoption is encouraged. The Company does not expect the adoption of SFAS No. 157 to have a significant effect on its financial position or results of operation.

2. Acquisition of BioCheck

On September 19, 2005, the Company entered into a stock purchase agreement with BioCheck and certain stockholders of BioCheck to purchase all of the common stock of BioCheck for $6.0 million in cash. BioCheck is a privately held California corporation engaged in the development of immunoassays, with a number of clinical diagnostic tests that have been approved by the United States Food and Drug Administration. On December 6, 2005, the Company purchased 51% of the common stock of BioCheck from each of the stockholders of BioCheck on a pro rata basis, for $3,060,000 in cash. This acquisition was accounted for by the purchase method of accounting according to Statement of Financial Accounting Standards No. 141, “Business Combinations,” (“SFAS No. 141”).

Pursuant to the stock purchase agreement, OXIS will use its reasonable best efforts to consummate a follow-on financing transaction to raise additional capital with which to purchase the remaining outstanding shares of BioCheck in one or more additional closings. The purchase price for any BioCheck shares purchased after the initial closing will be increased by an additional 8% per annum from December 6, 2005. If OXIS has not purchased all of the outstanding shares of BioCheck within twelve months of December 6, 2005, the earnings before interest, taxes, depreciation and amortization expenses, if any, of BioCheck, will be used to repurchase the remaining outstanding BioCheck shares at one or more additional closings. The purchase of the remaining outstanding shares of BioCheck will be accounted for the same as the initial purchase of 51% of BioCheck using the purchase method of accounting according to SFAS No. 141. The additional purchase price will be allocated over the purchased assets of BioCheck and the consolidated statements of operations will continue to include the results of operations of BioCheck reduced by the minority interest, if any, in BioCheck. The Company may obtain additional independent valuations of BioCheck’s assets related to the acquisition of the remaining 49% of BioCheck and additional acquisition costs may be incurred. Such information and costs may affect the disclosures as presented herein.

         On June 23, 2006, OXIS entered into a mutual services agreement with BioCheck. Both OXIS and BioCheck will provide certain services to the other corporation to be charged monthly at an hourly rate with an overhead surcharge. The services that BioCheck will provide include manufacturing the bulk of OXIS’ research assay test kits, assisting in packaging and shipping such research assay test kits to OXIS customers, and undertaking research and development of certain new OXIS research assay test kits on a case-by-case basis to be agreed upon between the parties. OXIS will provide services to BioCheck, including marketing and sales, website management and materials requirement and control systems.

The agreement terminates on December 6, 2009, or earlier upon mutual consent of the parties, upon 90 day prior written notice by either party, by either party if a monthly billing is unpaid after 60 days if a 15 day notice and opportunity to cure has been provided, or upon a material breach of the agreement after 30 days’ notice and opportunity to cure the breach. As of September 30, 2006, OXIS owed BioCheck approximately $103,000 for services rendered under the agreement. OXIS has not made that payment. If OXIS receives written notice of breach of the agreement due to this non-payment, it will have 15 days to cure that breach. If OXIS fails to cure the breach during the cure period, BioCheck would have the right to terminate the agreement.

On March 10, 2006, the Company received $200,000 in exchange for an unsecured promissory note with Steven T. Guillen, the Company’s president and chief executive officer at that time. The related party note bears interest at 7.0%. Interest and principal were due on September 10, 2006. Mr. Guillen’s employment with the Company was terminated on September 15, 2006. The Company was in default on this note at September 30, 2006. Subsequent to September 30, 2006, Mr. Guillen sued the Company for payment of interest and principal due under the note. On November 2, 2006, the Company repaid Mr. Guillen the principal and accrued interest due on the promissory note in the amount of $209,000. The purpose of this loan was to provide the Company with short term financing as it sought longer term financing.

On March 31, 2006, the Company issued a $400,000 unsecured promissory note to Fagan Capital, Inc. (“Fagan Capital”). Interest accrued at an annual rate of 8.0% and interest and principal were initially due on June 2, 2006. The purpose of this loan was to provide the Company with short term financing as it sought longer term financing. On July 26, 2006, Fagan Capital extended the maturity date of the promissory note by entering into a renewal and modification promissory note (“Renewal Note”). The Renewal Note had a principal amount of $406,000, comprised of the principal amount of the original promissory note plus accrued interest of $6,000. The effective date of the Renewal Note was June 2, 2006. On October 25, 2006, the Company paid to Fagan Capital amounts owing under the Renewal Note as described in Note 7.

In conjunction with the issuance of the Renewal Note, on July 26, 2006 the Company issued to Fagan Capital a common stock purchase warrant to purchase 1,158,857 shares of common stock at an initial exercise price of $0.35 per share. The exercise price is adjustable pursuant to certain anti-dilution provisions and upon the occurrence of a stock split. The common stock purchase warrant expires on June 1, 2014. On October 23, 2006, the parties signed a registration rights agreement covering the shares underlying the common stock purchase warrant. This warrant was valued using the Black-Scholes option-pricing model and the proceeds of $406,000 were allocated to the warrant and note based on their relative fair values. This resulted in the note being recorded as a liability at a discounted value of $240,000 and the warrant being record as equity under additional paid-in capital at a value of $166,000. The discounted note will accrete to its maturity value over the life of the loan. This resulted in a non-cash interest expense of $45,000 during the quarter ended September 30, 2006. With the payment of this note from the proceeds of the Company’s October 25, 2006 financing, the remaining discount of $121,000 will be accelerated and recorded as interest expense during October 2006.

4. Supplemental Cash Flow Disclosures

The Company recognized non-cash compensation expense of $58,000 and $8,000 related to the issuance and vesting of stock options issued to consultants in the nine months ended September 30, 2006 and 2005, respectively. The Company recognized non-cash compensation expense of $191,000 related to the issuance and vesting of stock options issued to employees in the nine months ended September 30, 2006. No employee non-cash compensation expense was recognized in the nine months ended September 30, 2005 prior to the implementation of SFAS 123R. Cash interest paid was $88,000 and $11,000 in the nine months ended September 30, 2006 and 2005, respectively. Interest expense attributed to the accretion of interest on discounted note payable was $45,000 in the three and nine months ended September 30, 2006.

5. Relocation of Operations
 
On December 6, 2005, the Company committed itself to a plan to cease operations in Portland, Oregon and relocate operations to Foster City, California (the “Relocation”). The Company decided to effect the Relocation after reviewing and evaluating all aspects of the Company’s operations to determine the profitability and viability of continuing in the Portland, Oregon location. During the first quarter of 2006, operations were relocated to California and on February 15, 2006 the Portland, Oregon facility was closed with the termination of employment of all Portland based employees who did not relocate to California. The Company’s subsidiary, BioCheck, has commenced shipping of the Company’s products and is manufacturing all of its research assay kit products not manufactured by third party suppliers.

In connection with the Relocation, the Company accrued $119,000 during 2005 for employee severances offered to all regular full-time employees who were not relocated to Foster City, California. Of this amount, $103,000 has been paid during the first nine months of 2006, resulting in $16,000 of accrued expenses at September 30, 2006. The Company expects $8,000 of this amount to be paid during the remainder of 2006 and $8,000 is to be paid during 2007. The Company accrues for these benefits in the period when benefits are communicated to the terminated employees. Typically, terminated employees are not required to provide continued service to receive termination benefits. In general, the Company uses a formula based on the number of years of service to calculate the termination benefits to be provided to affected employees.

In connection with the Relocation, the Company signed a lease agreement to occupy 4,136 square feet of space adjacent to space occupied by its BioCheck subsidiary in Foster City, California. The lease commenced on April 1, 2006 at an annual base rent of $62,000 per year that increases incrementally to $66,000 by the end of the lease term on March 31, 2009. In addition to the base rent, the Company will be responsible for its proportionate share of the building’s operating expenses and real estate taxes. The Company has a renewal option to extend the lease for one three-year period at the prevailing market rental value for rentable property in the same area.

6. Related Party Transactions

BioCheck and EverNew Biotech, Inc., a California corporation (“EverNew”), entered into a services agreement dated December 6, 2005 (the “Services Agreement”). The holders of the shares of capital stock of EverNew are substantially the same set of individuals and entities who held BioCheck’s common stock immediately prior to the initial closing of OXIS’ acquisition of BioCheck, including Dr. John Chen, President of BioCheck, as a significant stockholder. EverNew is an emerging point-of-care diagnostics company, with a number of products in development. EverNew renders certain services to BioCheck, including assay research and development work, and BioCheck renders certain administrative services to EverNew. In consideration of services provided by EverNew, BioCheck agreed to pay to EverNew $12,000 per month, provided, however, if the sum of EverNew’s gross revenues for a consecutive three month period during the term of the Services Agreement equals or exceeds $100,000, then BioCheck shall no longer be obligated to pay EverNew any amounts for the remainder of the term of the Services Agreement. Further, in such event, EverNew shall pay BioCheck an amount equal to the EverNew Service Cost per month for the remainder of the term of the Services Agreement, and the EverNew Service Cost for such month shall be reduced by the amount of the BioCheck compensation paid to BioCheck for such month under the Services Agreement. As used in the Services Agreement, EverNew Service Cost means the cost of all BioCheck services provided by BioCheck each month under the Services Agreement, as incurred and determined in good faith by BioCheck. Amounts due to EverNew from BioCheck are $129,000 and $194,000 at September 30, 2006 and December 31, 2005, respectively.

Pursuant to the employment agreement, Dr. Hausman will serve as the President and Chief Executive Officer of OXIS for a three year period from the Commencement Date, thereafter on a one year basis. Dr. Hausman will receive annual compensation in the amount of $250,000, payable quarterly in advance in cash, common stock based on a price equal to 85% of average of the five closing prices for the five trading days prior to the date that the issuance is authorized by the Board of Directors, or in ten year warrants equal to that number of warrants equal to 1.5 times the number of shares that would otherwise be received. For the initial quarterly payment, Dr. Hausman was issued 347,222 restricted shares of common stock. During the three year term of the agreement, Dr. Hausman shall receive an annual bonus based upon the attainment of agreed upon goals and milestones as determined by the Board of Directors and its Compensation Committee. During the remainder of calendar year 2006, Dr. Hausman’s bonus shall be pro rated on an annual bonus rate in the range of 25% to 50% of his base salary, and the bonus for subsequent years of the term of the agreement shall be in a similar target range. The bonuses payable hereunder shall be paid in cash, although at Dr. Hausman’s sole option, they may be paid in stock (or in the form of ten year warrants with cashless exercise provisions, with 1.5 times the number of warrant shares to be issued in lieu of the number of shares of common stock), based upon the average of the closing bid and asked prices for the 5 trading days immediately prior to the awarding to Dr. Hausman of the bonus for a particular year. Once OXIS has raised at least $2.5 million in one or more financings (equity, debt or convertible debt, in addition to the financing closed on October 25, 2006) or in a strategic transaction (in each case, a Qualifying Financing), Dr. Hausman may elect, at any time, in lieu of receiving a quarterly issuance of stock (or warrants in lieu thereof), to receive his base salary in cash, payable monthly on OXIS’s regular pay cycle for professional employees. As part of the compensation under the employment agreement, OXIS granted Dr. Hausman a ten year a non-qualified option to purchase 495,000 shares of OXIS common stock at an exercise price of $0.20 per share, vesting as follows: (i) 247,500 option shares vesting in four equal quarterly installments commencing on January 15, 2007 and every three months thereafter and (ii) and the remaining 247,500 option shares vesting in eight quarterly installments over two years (the “Initial Option Grant”). Additionally, OXIS granted Dr. Hausman, as a sign on bonus, 500,000 restricted shares of common stock and a ten year common stock purchase warrant to purchase 1,505,000 shares at an exercise price of $0.20 per share, with vesting in six equal installments, commencing on November 14, 2006, through the 180th day after the Commencement Date. OXIS shall provide Dr. Hausman with an annual office expense allowance of $50,000, for the costs of maintaining an office in the Stevenson, Washington area. The office expense allowance shall be payable quarterly in advance in the form of common stock, at a price equal to 85% of the Market Price. For the first installment, representing $12,500 of the office expense allowance, Dr. Hausman was issued 69,444 restricted shares of common stock. Hereafter, the office allowance expense will be paid promptly after the determination of the Market Price on the dates that are three months, six months and nine months from the date hereof, and quarterly thereafter for the duration of the term of the agreement. Notwithstanding the foregoing, once OXIS has completed a Qualifying Financing, the office expense allowance will be paid in cash in advance, commencing for the quarter next following the quarter in which the Qualifying Financing occurred. Additionally, Dr. Hausman shall receive family health and dental insurance benefits and short-term and long-term disability policies.

On October 25, 2006, OXIS entered into a securities purchase agreement (“Purchase Agreement”) with four accredited investors (the “Purchasers”). In conjunction with the signing of the Purchase Agreement, OXIS issued secured convertible debentures (“Debentures”) and Series A, B, C, D, and E common stock warrants (“Warrants”) to the Purchasers, and the parties also entered into a registration rights agreement and a security agreement (collectively, the “Transaction Documents”).
 
 
Pursuant to the terms of the Purchase Agreement, OXIS issued the Debentures in an aggregate principal amount of $1,694,250 to the Purchasers. The Debentures are subject to an original issue discount of 20.318% resulting in proceeds to OXIS of $1,350,000 from the transaction. The Debentures mature on October 25, 2008, but may be prepaid by OXIS at any time provided that the common stock issuable upon conversion and exercise of the Warrants is covered by an effective registration statement. The Debentures are convertible, at the option of the Purchasers, at any time, into shares of common stock at $0.35 per share, as adjusted pursuant to a full ratchet anti-dilution provision (the “Conversion Price”). Beginning on the first of the month following the earlier of the effective date of the registration statement to be filed pursuant to the registration rights agreement and February 1, 2007, OXIS shall amortize the Debentures in equal installments on a monthly basis resulting in a complete repayment by the maturity date (the “Monthly Redemption Amounts”). The Monthly Redemption Amounts can be paid in cash or in shares, subject to certain restrictions. If OXIS chooses to make any Monthly Redemption Amount payment in shares of common stock, the price per share is the lesser of the Conversion Price then in effect and 85% of the weighted average price for the 10 trading days prior to the due date of the Monthly Redemption Amount.

Pursuant to the Debentures, OXIS covenants that it will not incur additional indebtedness for borrowed money, other than its current Bridge Bank promissory note. OXIS also covenants that it will not pledge, grant or convey any new liens on its assets. The obligation to pay all unpaid principal will be accelerated upon an event of default, including upon failure to perform its obligations under the Debenture covenants, failure to make required payments, default on any of the Transaction Documents or any other material agreement, lease, document or instrument to which OXIS is obligated, the bankruptcy of OXIS or related events. The Purchasers have a right of first refusal to participate in up to 100% of any future financing undertaken by OXIS until the later of the date that the Debentures are no longer outstanding and the one year anniversary of the effective date of the registration statement. OXIS is restricted from issuing shares of common stock or instruments convertible into common stock for 90 days after the effective date of the registration statement with certain exceptions. OXIS is also prohibited from effecting any subsequent financing involving a variable rate transaction until such time as no Purchaser holds any of the Debentures. In addition, until such time as any Purchaser holds any of the securities issued in the Debenture transaction, if OXIS issues or sells any common stock or instruments convertible into common stock which a Purchaser reasonably believes is on terms more favorable to such investors than the terms pursuant to the Transaction Documents, OXIS is obligated to amend the terms of the Transaction Documents to such Purchaser the benefit of such better terms. OXIS may prepay the entire outstanding principal amount of the Debentures, plus accrued interest and other amounts payable, at its option at any time without penalty, provided that a registration statement is available for the resale of shares underlying the Debentures and Warrants, as more fully described in the Debentures. The purpose of this Debenture transaction is to provide the corporation with intermediate term financing as it seeks longer term financing.
 
On October 25, 2006, in conjunction with the signing of the Purchase Agreement, OXIS issued to the Purchasers five year Series A Warrants to purchase an aggregate of 2,420,357 shares of common stock at an initial exercise price of $0.35 per share, one year Series B Warrants to purchase 2,420,357 shares of common stock at an initial exercise price of $0.385 per share, and two year Series C Warrants to purchase an aggregate of 4,840,714 shares of common stock at an initial exercise price of $0.35 per share. In addition, OXIS issued to the Purchasers Series D and E Warrants which become exercisable on a pro-rata basis only upon the exercise of the Series C Warrants. The six year Series D Warrants to purchase 2,420,357 shares of common stock have an initial exercise price of $0.35 per share. The six year Series E Warrants to purchase 2,420,357 shares of common stock have an initial exercise price of $0.385 per share. The initial exercise prices for each warrant are adjustable pursuant to a full ratchet anti-dilution provision and upon the occurrence of a stock split or a related event.
 
Pursuant to the registration rights agreement, OXIS must file a registration statement covering the public resale of the shares underlying the Series A, B, C, D and E Warrants and the Debentures within 45 days of the closing of the transaction and cause the registration to be declared effective within 120 days of the closing date. Cash liquidated damages equal to 2% of the face value of the Debentures per month are payable to the purchasers for any failure to timely file or obtain an effective registration statement.
 
Pursuant to the Security Agreement, OXIS agreed to grant the purchasers, pari passu, a security interest in substantially all of the Company’s assets. OXIS also agreed to pledge its respective ownership interests in its wholly-owned subsidiaries, OXIS Therapeutics, OXIS Isle of Man, and its partial subsidiary, BioCheck, Inc. OXIS Therapeutics and OXIS Isle of Man also provided a subsidiary guarantee to the Purchasers in connection with the transaction.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
September 30, 2006
On September 15, 2006, Steven T. Guillen’s employment as the Company’s President and Chief Executive Officer was terminated. Mr. Guillen remains a member of the board of directors. Pursuant to the employment agreement with Mr. Guillen and in connection with his termination, the Company accrued $261,000 at September 30, 2006 for severance obligations including continued coverage under the Company’s health plan. The Company expects $76,000 of this amount to be paid during the remainder of 2006 and $185,000 is to be paid during 2007 contingent upon Mr. Guillen’s execution of a waiver and release of all claims against the Company. In addition, the Company accrued back salary of approximately $75,000 at September 30, 2006 owed to Mr. Guillen. On October 16, 2006, Mr. Guillen filed a lawsuit against the Company and up to 25 unnamed additional defendants. The complaint alleges breaches of contract relating to Mr. Guillen’s employment agreement and a promissory note that is in default, breach of implied covenant of good faith and fair dealing, wrongful termination and violation of the California Labor Code in relation to the non-payment of back pay. On March 10, 2006, we received $200,000 in exchange for an unsecured promissory note with Mr. Guillen. Interest and principal were due on September 10, 2006 and at September 30, 2006 were in default. On November 2, 2006, the Company repaid Mr. Guillen the principal and accrued interest due on the promissory note in the amount of $209,000 and back pay with penalties and accrued interest of $96,000. We are in ongoing negotiations with Mr. Guillen’s counsel to settle the lawsuit. To the date of this prospectus, the complaint has not been served upon OXIS or any other defendant.

The Company issued a $400,000 unsecured promissory note to Fagan Capital on March 31, 2006 and a modification and renewal note on July 26, 2006 as described in Note 3. In conjunction with the issuance of the renewal note, the Company issued to Fagan Capital a common stock purchase warrant. On October 25, 2006, the Company prepaid the principal, accrued interest and legal fees due pursuant to the renewal note in the amount of $426,000.

PART II
 
INFORMATION NOT REQUIRED IN PROSPECTUS
 
Indemnification of Directors and Officers
 
As permitted by Delaware law, our certificate of incorporation provides that we will indemnify our directors and officers against expenses and liabilities they incur to defend, settle, or satisfy any civil, criminal, administrative or investigative proceeding brought against them on account of their being or having served as our directors or officers to the fullest extent permitted by Delaware law. Further, we have entered into an indemnification agreement with each of our directors providing, among other things, for indemnification and advancement of certain litigation-related expenses.
 
We maintain directors and officers liability insurance with an aggregate coverage limit of $4,000,000. Our directors and officers may also be covered by directors and officers liability insurance coverage of Axonyx, the aggregate coverage limits of which are $25,000,000, for period during which our directors and officers meet the definition of insureds under such policy.
 
Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be permitted to directors, officers or persons controlling our company pursuant to the foregoing provisions, we have been informed that in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Warrant Exercise and Issuance of New Warrants

During July 2003, our board of directors offered all holders of warrants a reduced exercise price for a limited period of time. The exercise price for these warrants was reduced to $0.20 per shares, and maturity date for 598,449 warrants issued in 1998 was extended to August 11, 2003. The exercise price for these warrants was previously $1.00 per share. All warrants issued prior to July 1998 had lapsed and were not affected by this board action. The decrease of exercise price did not result in any change to the outstanding value of the warrants. Pursuant to the offered reduced exercise price, a total of 1,133,000 warrants were exercised at an aggregate purchase price of $226,600. As part of the offer, with each share of stock issued one new warrant was issued having a $1.00 exercise price and exercisable for two years.

Bridge Loan Transaction

On January 14, 2004, we completed a private placement of securities, pursuant to which (i) certain bridge loan investors (referred to as “note holders”) paid to us $570,000 in the aggregate, (ii) we issued promissory notes due on the first anniversary date of issuance or immediately on an acquisition, bearing 7% interest per annum, to the investors in principal amount of $570,000 in the aggregate, which promissory notes are convertible in due course into our common stock at a rate of one share for each $0.40 of principal and interest outstanding, or in the “event of default” under these promissory notes by us, into our common stock at a rate of one share for each $0.15 of principal and interest outstanding, and (iii) we issued warrants to the investors, exercisable for up to 712,500 shares of our common stock at an exercise price of $0.50 per share.
 
On December 30, 2004, we received notices from each of the promissory note holders electing under the terms of such promissory notes to convert all debt under the promissory notes plus related accrued interest into an aggregate of 1,520,932 shares of our common stock. In connection with the promissory note holders to election to convert such debt, we agreed to issue to the promissory note holders warrants exercisable for a period of five years for the purchase of up to an aggregate of 760,469 shares of our common stock at an exercise price of $1.00 per share.
 
The private placement of the securities to promissory note holders was exempt from registration under the Securities Act, pursuant to Section 4(2) thereof, and Rule 506 promulgated by the SEC under the Securities Act.
 
Private Placement Transaction
 
On December 30, 2004, we entered into definitive agreements with investors relating to the private placement of $6.5 million of its securities through the sale of 12,264,158 shares of its common stock at $0.53 per share. This private placement transaction was closed on January 6, 2005. The transaction resulted in the issuance on or about January 10, 2005 of 12,264,158 shares of our common stock for which we received gross proceeds of $0.53 per share. In addition, on January 6, 2005, we issued to the purchasers in the private placement transaction warrants to purchase an additional 12,264,158 shares of our common stock, 50% at an exercise price of $0.66 per share and 50% at an exercise price of $1.00 per share.
 
Upon the closing of the private placement transaction, as partial consideration for services rendered as the placement agent for the private placement transaction, we issued to Rodman & Renshaw, LLC a warrant to purchase 306,604 shares of our common stock at an exercise price of $0.66 per share and a warrant to purchase 306,604 shares of our common stock at an exercise price of $1.00 per share.
 
The offer, sale and issuance of securities to the purchasers in the private placement was exempt from registration under the Securities Act, pursuant to Section 4(2) thereof, and Rule 506 promulgated by the SEC under the Securities Act.

Conversion of $160,000 in Principal Debt into Common Stock
 
On May 23, 2005, we entered into a conversion agreement with Equitis Entreprise, a French société par actions simplifiée (“Equitis”), under which Equitis converted a promissory note originally issued by us on April 9, 1997 to Finovelec, a French société anonyme and subsequently transferred to Equitis, representing $243,458.63 in aggregate debt, at a conversion price of $0.53 per share of our common stock, into an aggregate of 459,355 shares of our common stock. The amount owed by us under this promissory note consisted of $160,000 in principal debt, $4,800 in loan origination fees and $78,658.63 in accrued and unpaid interest at 8% per annum for the period of April 1, 1999 through May 23, 2005. The issuance of 459,355 shares of our common stock to Equitis is exempt from registration under the Securities Act, pursuant to Section 4(2) thereof, and Regulation D promulgated by the SEC thereunder.

Conversion of Series B Preferred Stock into Common Stock

During the third quarter of 2005, 428,389 outstanding shares of Series B preferred stock were converted into 85,678 shares of common stock. The Series B preferred stock had certain preferential rights with respect to liquidation and dividends. Holders of Series B preferred stock were entitled to noncumulative annual dividends at the rate of $0.115 per share if and when declared by our board of directors. No dividends to Series B preferred stockholders were issued or unpaid during 2005. The private placement was exempt from registration under Section 4(2) of the Securities Act of 1933.

Convertible Debenture and Warrant Financing

On October 25, 2006, we issued convertible debentures to investors in an aggregate principal amount of $1,694,250. The debentures were issued with an original issue discount of 20.318% resulting in proceeds to us of $1,350,000 from the transaction. Also, in connection with this financing, we issued Series A, B, C, D and E warrants to investors for the purchase of an aggregate of approximately 14.5 million shares of our common stock, at an initial exercise price of $0.35 per share, subject to adjustment as provided therein. Reference is made to the disclosures in Part I in the section above entitled “Recent Financing,” and to the current report on Form 8-K filed with the SEC on October 26, 2006.

These securities were offered to accredited investors in reliance on an exemption from the registration requirements of the Securities Act of 1933 (the “Securities Act”) under Regulation D. The offering has not been registered under the Securities Act or any state securities of “blue sky” laws, and the securities may not be offered or sold absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state securities laws.

UNDERTAKINGS
 
The undersigned registrant hereby undertakes to:
 
File, during any period in which offers or sales are being made, a post-effective amendment to this registration statement to:
 
1.  
Include any prospectus required by Section 10(a)(3) of the Securities Act;
 
2.  
Reflect in the prospectus any facts or events which, individually or together, represent a fundamental change in the information in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of the securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) under the Securities Act if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement, and
 
3.  
Include any additional or changed material information on the plan of distribution.

For determining liability under the Securities Act, treat each post-effective amendment as a new registration statement of the securities offered, and the offering of the securities at that time to be the initial bona fide offering.
 
File a post-effective amendment to remove from registration any of the securities that remain unsold at the end of the offering.
 
Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.
 
In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
