1.		Basis of Presentation
		SciClone was reincorporated in the State of Delaware on July 18, 2003. The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with generally accepted accounting principles consistent with those applied in, and should be read in conjunction with, the audited financial statements for the year ended December 31, 2003 included in the Company’s Form 10-K as filed with the Securities and Exchange Commission. The interim financial information reflects all adjustments, consisting of only normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the results for the interim periods presented. The results of operations for the three months ended March 31, 2004 are not necessarily indicative of results for subsequent interim periods or for the full year. The condensed consolidated balance sheet data at December 31, 2003 is derived from the audited financial statements at that date, but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.
2.		Significant Accounting Policies
		Revenue Recognition
		The Company recognizes revenue from product sales at the time of shipment. There are no significant customer acceptance requirements or post shipment obligations on the part of the Company. Sales to importing agents or distributors are recognized at time of shipment when title to the product is transferred to them, and they do not have contractual rights of return except under limited terms regarding product quality. However, the Company will replace products that have expired or are deemed to be damaged or defective when delivered. Payments by the importing agents and distributors are not contingent upon sale to the end user by the importing agents or distributors.
		Contract revenue for research and development is recorded as earned based on the performance requirements of the contract. Nonrefundable contract fees for which no further performance obligations exist, and there is no continuing involvement by the Company, are recognized on the earlier of when the payments are received or when collection is assured.

6

		Revenue associated with substantive performance milestones is recognized based on the achievement of the milestones, as defined in the respective agreements and provided that (i) the milestone event is substantive and its achievement is not reasonably assured at the inception of the agreement, and (ii) there are no future performance obligations associated with the milestone payment.
		Net Loss Per Share
		Net loss per share is computed using the weighted average number of shares of common stock outstanding. Potentially dilutive common shares from convertible debt, stock options and warrants are excluded, as their effect is antidilutive.
		Accounting For Stock-Based Compensation
		The Company accounts for its stock option and employee stock purchase plans under the provisions of Accounting Principles Board Opinion 25 (“APB 25”) and related Interpretations. Accordingly, the Company does not recognize compensation expense in accounting for its stock option and employee stock purchase plans for awards to employees and directors granted with exercise prices at fair market value.
		Pro forma information regarding net loss and net loss per share is required by Statement of Financial Accounting Standards No. 123 “Accounting for Stock-Based Compensation” (“SFAS 123”) as amended by Statement of Financial Accounting Standards No. 148 “Accounting for Stock-Based Compensation-Transition and Disclosure” (“SFAS 148”) and has been determined as if the Company had accounted for its stock awards under the fair value method of that Statement. The fair value for the options was estimated at the date of grant using a Black-Scholes option pricing model with the following weighted-average assumptions for both the three-month period ended March 31, 2004 and the corresponding period in 2003: risk-free interest rate of 2.20% and 2.00%, respectively; dividend yield of 0%; volatility of 0.93 and 0.95, respectively, and a weighted average expected life of the option of 4.00 years.
		The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility. Because the Company’s employee stock awards have characteristics significantly different from those of traded options, and because changes in subjective input assumptions can materially affect the fair value estimate, in the Company’s opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its employee and director stock options and stock purchases.
		The following table illustrates the Company’s pro forma net loss and net loss per share, had compensation expense for the Company’s option and employee purchase plans been determined based on the fair value at the grant date consistent with the provisions of SFAS 123, as amended by SFAS 148:

The effects of applying SFAS 123 for pro forma disclosures are not likely to be representative of the effects on reported net loss for future years due to the different number of options granted each year.

3.		Comprehensive Loss
		For the three-month periods ended March 31, 2004 and 2003, the Company’s total comprehensive loss amounted to $3,077,000 and $2,883,000 respectively.
4.		Available-For-Sale Securities
		The following is a summary of available-for-sale securities at March 31, 2004 and December 31, 2003:

As of March 31, 2004, the available-for-sale securities are included as follows: $32,867,000 in cash            and cash equivalents, $694,000 in restricted short-term investments and $9,437,000 in other short-term investments. As of December 31, 2003, the available-for-sale securities are included as follows: $38,259,000 in cash and cash equivalents, $695,000 in restricted short-term investments and $9,380,000 in other short-term investments. As of March 31, 2004 and December 31, 2003 all available-for sale securities excluding the short-term municipal securities had maturities of 12 months or less. The short-term municipal securities are auction rate securities which have final maturities of 21-36 years, however, because they are highly rated, highly liquid and their interest rate is reset at auction every 30 days, our interest rate risk associated with these securities is limited due to this interest rate reset mechanism.

Inventories

The following is a summary of inventories at March 31, 2004 and December 31, 2003:

6.

Intangible Assets

The following is a summary of intangible assets:

		Acquired ZADAXIN product rights are being amortized on a straight-line basis beginning in September 1998. Amortization expense for each of the three-month periods ended March 31, 2004 and 2003 was $17,500. For the years ending December 31, 2004 through 2012, annual amortization expense is expected to be $70,000. Based upon the progress in the ZADAXIN clinical trials and the Company’s actual experience of product sales, the Company has assessed that the acquired product rights will be useful to the Company through 2012 when the European patent for the use of ZADAXIN in the treatment of hepatitis C expires. The Company’s policy is to identify and record impairment losses, as circumstances dictate, on intangible product rights when events and circumstances indicate that the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amounts of those assets.
7.		Deferred Revenue
		In January 2002, the Company received $2,685,000 from its European partner, Sigma-Tau under the terms of its collaborative agreement announced in late December 2001. This receipt has been recorded as deferred revenue and is being recognized as contract revenue over the course of the ZADAXIN hepatitis C U.S. clinical program beginning in April 2002 and through the period of sharing the clinical data from this program with Sigma-Tau, the substantive performance requirements under the contract. For the three-month period ended March 31, 2004 and 2003, the Company recognized $134,000 and $224,000, respectively as contract revenue from this agreement.

We undertake no obligation to revise or update publicly any forward-looking statements for any reason.

Overview

     SciClone Pharmaceuticals, Inc. is a biopharmaceutical company engaged in the development and commercialization of therapeutics to treat life-threatening diseases. We are currently evaluating our lead product, ZADAXIN, in several late stage clinical trials for the treatment of patients with the hepatitis C virus, or HCV, the hepatitis B virus, or HBV, and certain types of cancer. Our primary focus is the successful completion of our two ongoing ZADAXIN phase 3 HCV clinical trials in the United States. We believe the worldwide market for HCV therapies was approximately $3 billion in 2003 and could exceed $8 billion in 2012. If approved by the U.S. Food and Drug Administration (FDA), we expect ZADAXIN to complement other HCV therapies and to expand the HCV market opportunity. In addition to the HCV trials in the United States, we are also evaluating ZADAXIN in a recently completed phase 3 HBV clinical trial in Japan, an ongoing phase 2 malignant melanoma clinical trial in Europe with our exclusive marketing partner for Western Europe, Sigma-Tau, two ongoing phase 2 pilot studies in the United States for the treatment of liver cancer, an ongoing HCV pilot clinical trial in Mexico and an ongoing HBV clinical trial in Taiwan. Our other principal drug development candidate is SCV-07, a potentially orally available therapeutic to treat viral and infectious diseases.

Results of Operations

     Total Revenue

     Product sales were $5,414,000 for the three-month period ended March 31, 2004 and $5,000,000 for the corresponding period in 2003. All product sales in each period were derived from sales of ZADAXIN. The increase was attributable to a higher volume of product sold as prices have remained stable. Sales to customers in China accounted for approximately 88% and 87% of this revenue for the three-month periods ended March 31, 2004 and 2003, respectively.

     For the three-month period ended March 31, 2004, sales to two importing agents in China accounted for approximately 50% and 38% of our product sales respectively. For the three-month period ended March 31, 2003, one importing agent accounted for 87% of our product sales; however, this importing agent accounted for only 38% of our product sales in the three-month period ended March 31, 2004. We rely on six

10

importers to supply substantially all of our product in China, and our sales to any single importing agent can vary substantially from quarter to quarter depending on the size and timing of the orders. As of March 31, 2004, approximately $9,323,000, or 85%, of our accounts receivable were attributable to four customers in China. We perform on-going credit evaluations of our customers’ financial condition, and generally do not require collateral from our customers.

     Contract revenue was $228,000 and $224,000 for the three-month periods ended March 31, 2004 and 2003, respectively. We recognized $134,000 of contract revenue for the three-month period ended March 31, 2004, and all of the contract revenue for the corresponding period in 2003 in connection with the $2,685,000 payment we received from Sigma-Tau in January 2002. This revenue is recognized as contract revenue over the course of the ZADAXIN hepatitis C U.S. clinical program and the period of sharing the clinical data from this program with Sigma-Tau in accordance with the requirements under our contract with Sigma-Tau. We also recognized $94,000 of contract revenue in the three-month period ended March 31, 2004 in connection with a National Institutes of Health grant that we earned in the period.

     Cost of Product Sales and Gross Margin

     Gross margin on sales was 79% for the three-month period ended March 31, 2004, and 80% for the corresponding period in 2003. The decrease in gross margin percentage was primarily the result of temporarily higher product costs in connection with our use of a new manufacturer for ZADAXIN and foreign currency rate fluctuations, as purchases from one of our contract manufacturers are denominated in euros. We expect cost of product sales, and therefore gross margin, to vary from period to period, depending upon the level of ZADAXIN sales, the absorption of product-related fixed costs, and any charges associated with excess or expiring finished product inventory.

     Research and Development

     Research and development expenses were $3,931,000 for the three month-period ended March 31, 2004 and $3,783,000 for the corresponding period in 2003. The increase was primarily to support our ZADAXIN phase 3 clinical trials in the United States. The initiation and continuation of our current clinical development programs has had and will continue to have a significant effect on our research and development expenses. We expect a substantial increase in research and development expenses during the second quarter of 2004 compared to the first quarter of the current year and to the second quarter of 2003. The expected increase is primarily due to an anticipated increase in expenses relating to our phase 3 HCV clinical trials and other increases in research and development expenses. Due to the uncertain nature of the clinical trial process, and enrollment rates in particular, it is not possible to determine the timing of completion or total cost expected to be incurred for each trial. In general, we expect research and development expenses to increase significantly at least over the next two years and to vary substantially from quarter to quarter as we pursue our strategy of initiating additional preclinical and clinical trials and testing, acquiring product rights, and expanding regulatory activities.

     Sales and Marketing

     Sales and marketing expenses were $2,443,000 for the three-month period ended March 31, 2004 and $2,229,000 for the corresponding period in 2003. The increase was related to increased payroll expenses and expenses for advertising and conferences associated with the expansion of our markets for ZADAXIN. We expect sales and marketing expenses to increase in the next several quarters and years as we expand our commercialization and marketing efforts.

11

     General and Administrative

     General and administrative expenses were $1,293,000 for the three-month period ended March 31, 2004 and $1,012,000 for the corresponding period in 2003. The increase was primarily attributable to greater general and administrative activities associated with increased securities regulation requirements. In the near term, we expect general and administrative expenses to vary quarter to quarter as we increase our general and administrative activities and resources to support increased expenditures on preclinical and clinical trials and testing, and regulatory, pre-commercialization and marketing activities.

     Interest and Investment Income and Expense

     Interest and investment income was approximately $116,000 for the three-month period ended March 31, 2004 and $53,000 for the corresponding period in 2003. The increase was primarily the result of larger cash balances earning interest in the 2004 period due to the proceeds we received from our follow-on public offering of common stock during the third quarter of 2003. Interest expense relating to $5,600,000 of convertible notes payable was $84,000 for each of the three-month periods ended March 31, 2004 and 2003.

     Liquidity and Capital Resources

     At March 31, 2004 and December 31, 2003, we had $58,253,000 and $62,975,000, respectively, in cash, cash equivalents and short-term investments. We currently estimate that cash, cash equivalents and short-term investments at December 31, 2004 will be lower than the balance at March 31, 2004. The expected decrease in this balance is attributable to an expected net loss and no plans for a financing during the current fiscal year. The short-term investments consist primarily of highly liquid marketable securities. We have two letters of credit each secured by a certificate of deposit. At March 31, 2004 and December 31, 2003, the letters of credit totaled $694,000, one for $633,000 under our lease agreement, the other for $61,000 to facilitate our value added tax filings in Europe.

     Net cash used in operating activities totaled $4,829,000 and $5,490,000 for the three-month periods ended March 31, 2004 and 2003, respectively. Net cash used in operating activities for the three-month period ended March 31, 2004 was more than the net loss primarily due to a $1,563,000 decrease in accounts payable.

     Net cash provided by financing activities totaled $70,000 and $1,948,000 for the three-month periods ended March 31, 2004 and 2003, respectively. Net cash provided by financing activities for the three-month period ended March 31, 2003 primarily consisted of approximately $1,800,000 generated from the issuance of common stock to Sigma-Tau.

     We intend to give priority use of our financial resources to ZADAXIN clinical programs in the United States. We believe our existing capital resources and funds from product sales are sufficient to complete our current U.S. phase 3 clinical trials and, if the trials are successful and we receive FDA approval, to begin commercialization of ZADAXIN in the United States. However, we cannot assure you that such funds will be sufficient, or that sales of ZADAXIN, if approved in the United States, will result in profitable operations. An expansion or significant extension of our clinical development programs may require us to seek additional capital resources. In the event we need to raise additional funds, the unavailability or the inopportune timing of any financing could prevent or delay our long-term product development and commercialization programs, either of which would severely hurt our business. The need, timing and amount of any such financing would depend upon numerous factors, including the level of ZADAXIN sales, the timing and amount of manufacturing costs related to ZADAXIN, the availability of complementary products, technologies and businesses, the initiation and continuation of preclinical and clinical trials and testing, the timing of regulatory approvals, developments in relationships with existing or future collaborative parties and the status of competitive products.

12

Contractual Obligations

     There were no material changes to our contractual obligations in the three-month period ended March 31, 2004.

Off-Balance Sheet Arrangements

     There were no off-balance sheet arrangements in the three-month period ended March 31, 2004.

Risk Factors

     You should carefully consider the risks described below, in addition to the other information in this report on Form 10-Q and our report on Form 10-K for the year ended December 31, 2003, before making an investment decision. Each of these risk factors could adversely affect our business, financial condition, and operating results as well as adversely affect the value of an investment in our common stock.

If we are unable to commercialize ZADAXIN in various markets for multiple indications, particularly in the United States for the treatment of HCV, our business will be harmed.

     Our ability to achieve and sustain operating profitability depends in large part on our ability to commence, execute and complete clinical programs and obtain additional regulatory approvals, for ZADAXIN and other drug candidates, particularly in the United States, Europe and Japan. We are also dependent on our ability to increase ZADAXIN sales in existing markets and launch ZADAXIN in new markets. In particular, our ability to achieve and sustain profitability will depend in large part on our ability to commercialize ZADAXIN for the treatment of HCV in the United States. We cannot assure you that we will achieve significant levels of sales or that we will receive approval for ZADAXIN for the treatment of HCV in the United States or for the treatment of HCV or other indications in other countries. If we are unable to do so, our business will be harmed.

If we do not obtain regulatory approval for ZADAXIN for the intended indications that we are evaluating, our revenues will be limited and we will not become profitable.

     Our ability to execute on our business strategy requires that we obtain regulatory approval for the use of ZADAXIN, particularly for the treatment of HCV in the United States, both HBV and HCV in Japan and both HCV and malignant melanoma in Europe. If our current phase 3 trials in the United States and current and future trials in Europe yield favorable results, we intend to submit applications for marketing approval of ZADAXIN for the treatment of HCV in the United States and through our partner, Sigma-Tau, for the treatment of HCV and malignant melanoma in Europe. Based on the results of our recently completed phase 3 trial in Japan, we intend to submit a regulatory filing for the treatment of HBV in Japan. The regulatory approval processes in the United States, Europe and Japan are demanding and typically require 12 months or more in the United States and 18 months or more in Europe and Japan from the date of submission of a New Drug Application. We have committed significant resources, including capital and time, to develop ZADAXIN, particularly for HCV in the United States, with the goal of obtaining such approvals. If we do not obtain these approvals, we will be unable to achieve any substantial increase in our revenue.

     All new drugs, including our products, which have been developed or are under development, are subject to extensive and rigorous regulation by the FDA and comparable agencies in state and local jurisdictions and in foreign countries. These regulations govern, among other things, the development, testing, manufacturing, labeling, storage, pre-market approval, importation, advertising, promotion, sale and distribution of our products. These regulations may change from time to time and new regulations may be adopted.

13

     Obtaining regulatory approval in developing countries is also time-consuming and expensive. In some countries where we are contemplating marketing and selling ZADAXIN, the regulatory approval process often relies on prior approvals obtained in the United States, Europe or Japan. Without such prior approvals, our ability to obtain regulatory approvals for ZADAXIN in these countries may be delayed or prevented. In addition, to secure these regulatory approvals, we will need, among other things, to demonstrate favorable results from additional clinical trials of ZADAXIN. Even if we are able to complete the clinical trials we have sponsored or are planning in a timely or cost-effective manner, these trials may not fulfill the applicable regulatory approval criteria, in which case we will not be able to obtain regulatory approval in these countries. We cannot assure you that we will ultimately obtain regulatory approvals in our targeted countries in a timely and cost-effective manner or at all. If we fail to obtain the required regulatory approvals to develop, market and sell our products in countries where we currently do not have such rights, our revenues will be limited.

     Satisfaction of government regulations may take several years and the time needed to satisfy them varies substantially based on the type, complexity and novelty of the pharmaceutical product. As a result, government regulation may cause us to delay the introduction of, or prevent us from marketing, our existing or potential products for a considerable period of time and impose costly procedures upon our activities. Even if we obtain regulatory approval for our products, such approval may impose limitations on the indicated uses for which our products may be marketed. Unsatisfactory data resulting from clinical trials may also adversely affect our ability to market and sell ZADAXIN in markets where it is approved for sale.

If the results of our clinical trials are not favorable, we will be unable to obtain regulatory approval for the intended indications we are evaluating.

     To obtain regulatory approvals, we must, among other requirements, complete carefully controlled and well-designed clinical trials demonstrating that a particular drug is safe and effective for the applicable disease. We cannot depend on data from prior trial results to predict or demonstrate that our drug products are safe and efficacious under regulatory guidelines to qualify for commercial sale. We cannot assure you, nor can you rely on our previous clinical trial results to predict, that our ongoing or future clinical trials will yield favorable results. Adverse or inconclusive clinical results would prevent us from filing for regulatory approval of ZADAXIN for the indications that we are evaluating, and our current programs in those areas would fail. In the past, Alpha 1 Biomedical, from which we acquired certain rights to thymosin alpha 1, conducted a phase 3 clinical trial of thymosin alpha 1 as a therapy for HBV that did not produce statistically significant results and Alpha 1 Biomedical did not submit a new drug application to the FDA.

     We are currently conducting phase 3 clinical trials based on the use of ZADAXIN in combination with pegylated interferon alpha for the treatment of HCV patients who did not previously respond to treatment. We cannot assure you that these phase 3 clinical trials will yield sufficient or adequate data to demonstrate appropriate safety and efficacy under FDA guidelines. Any failure to obtain sufficient or adequate data could delay or prevent us from securing FDA approval.

     Our two phase 3 HCV clinical trials in the United States have been designed to show that the combination of ZADAXIN and pegylated interferon alpha adds a significant clinical benefit when compared to the use of pegylated interferon alpha alone in non-responders. We cannot assure you that the results of this combination therapy will yield the favorable results we expect, or that the independent use of pegylated interferon alpha will not perform better than anticipated, which could reduce the chances that a new drug application, or NDA, will be approved. If the combination therapy of ZADAXIN and pegylated interferon alpha causes significant adverse side effects beyond those caused by pegylated interferon alpha alone, our clinical trials could be delayed, patients may drop out at a greater than anticipated rate, we may be forced to halt the trials or the FDA may reject an NDA due to safety issues. If any of the foregoing occurs, our efforts to

14

market and sell ZADAXIN in the United States will be significantly impaired, our business will suffer and the price of our stock may decline.

     Our phase 3 HBV clinical trial in Japan was designed to demonstrate a clinical benefit measured by an analysis of a combination of safety and efficacy data points. We cannot assure that the results of this study will warrant favorable consideration by the Japanese Ministry of Health and Welfare or result in a marketing registration of ZADAXIN. If additional studies or other data are required for regulatory consideration, our efforts to market and sell ZADAXIN in Japan will be significantly impaired, our business will suffer and the price of our stock may decline.

If we experience delays in patient enrollment in our clinical trials, we may not be able to obtain regulatory approval in accordance with our anticipated timeline.

     Each of our two current phase 3 HCV clinical trials in the United States are designed to enroll 500 patients, one trial treating patients with no liver damage and the other trial treating patients with mild cirrhosis of the liver. The 500 patient enrollment is complete in the first trial, however if we are unable to enroll a sufficient number of patients in the second trial, if such enrollment is delayed or if patient drop out rates in either trial are higher than anticipated, our ability to proceed with our clinical trials and prepare an NDA would be adversely affected. In particular, we are experiencing competition for patients with mild cirrhosis of the liver, from trials sponsored by other commercial drug developers and from a trial sponsored by the National Institutes of Health. Competition for the enrollment of similar patients in other clinical trials or other delays in enrollment may prevent us from enrolling patients quickly enough to meet our current timing expectations for completing our phase 3 trials, which would delay the preparation of an NDA. If we are not able to fully enroll patients for both of these clinical trials or patient drop out rates are higher than anticipated, it could reduce the chances that our NDA will be approved.

We cannot predict the safety profile of the use of ZADAXIN when used in combination with other drugs.

     Many of our trials involve the use of ZADAXIN in combination with other drugs. Some of these drugs are known to cause adverse patient reactions. Even if ZADAXIN does not produce adverse side effects when used alone, we cannot predict how it will work with other drugs, including causing possible adverse side effects not directly attributable to the other drugs that could compromise the safety profile of ZADAXIN when used in certain combination therapies.

Due to the outbreak of SARS in China, sales of ZADAXIN in the second quarter of 2003 were significantly higher than expected and are not indicative of future sales.

     Our sales for the quarter ended June 30, 2003 were more than 200% greater than sales for any quarter in our history as a result of a previously unanticipated increase in sales of ZADAXIN to hospitals in China. This increase was related to the use of immune system enhancers, including ZADAXIN, in connection with the treatment of severe acute respiratory syndrome, or SARS. In future quarters, sales of ZADAXIN for the treatment of SARS could be affected by changes in treatment in China, changes in the rate of infection and the emergence of evidence as to the effectiveness or ineffectiveness of ZADAXIN or of other potential treatments for SARS.

     As a result of the containment of the SARS epidemic, we expect sales in future quarters to be more consistent with sales patterns of the third and fourth quarters of 2003 and the quarter ended March 31, 2004, each of which have significantly lower sales results than those of the second quarter in 2003. We could experience fluctuations in sales in future quarters as a result of similar factors.

15

Our sales of ZADAXIN may fluctuate due to seasonality of product orders and sales in any quarter may not be indicative of future sales.

     Our sales for the quarter ended June 30, 2003 were greatly affected by the demand in China for ZADAXIN in connection with the treatment of SARS. It is not possible to predict at this time if SARS will re-emerge, like influenza, as a seasonal public health problem and what effect, if any, this would have on future sales of ZADAXIN. To the extent that ZADAXIN is purchased in connection with future outbreaks of SARS or other seasonal viral contagions, product sales could become more concentrated in certain quarters of the calendar year. Quarterly sales levels could fluctuate and sales in any quarter may not be indicative of sales in future periods.

Our revenue is dependent on the sale of ZADAXIN in foreign countries, particularly China, and if we experience difficulties in our foreign sales efforts, our financial condition will be harmed.

     Our product revenue in the near term is highly dependent on the sale of ZADAXIN in foreign countries. If we experience difficulties in our foreign sales efforts, our business will suffer and our financial condition will be harmed. Substantially all of our ZADAXIN sales are to customers in China. Sales of ZADAXIN in China may be limited due to the low average personal income, lack of patient cost reimbursement, poorly developed infrastructure and existing and potential competition from other products, including generics. Several local companies have introduced lower priced locally manufactured generic competitive products. If these sales continue, there could be a negative impact on the price and the volume of ZADAXIN sold in China and this would harm our business.

     In addition, our ZADAXIN sales and operations in other parts of Asia, as well as in Latin America and the Middle East, are subject to a number of risks, including difficulties and delays in obtaining registrations, permits, pricing approvals and reimbursement and unexpected changes in regulatory requirements. In addition, we experience other issues with managing foreign sales operations including long payment cycles, difficulties in accounts receivable collection and, especially from significant customers, fluctuations in the timing and amount of orders. Operations in foreign countries also expose us to risks relating to difficulties in enforcing our proprietary rights, currency fluctuations and adverse or deteriorating economic conditions.

     We do not have product sales in the United States with which to offset any decrease in our revenue from ZADAXIN sales in Asia, Latin America and the Middle East. In addition, some countries in these regions, including China, regulate pharmaceutical prices and pharmaceutical importation. These regulations may reduce prices for ZADAXIN to levels significantly below those that would prevail in an unregulated market, limit the volume of product which may be imported and sold or place high import duties on the product, any of which may limit the growth of our revenues or cause them to decline.

Because of China’s tiered method of importing and distributing finished pharmaceutical products, our quarterly results may vary substantially from one period to the next.

     China uses a tiered method to import and distribute finished pharmaceutical products. At each port of entry, and prior to moving the product forward to the distributors, government-licensed importing agents must process and evaluate each shipment to determine whether such shipment satisfies China’s quality assurance requirements. In order to efficiently manage this process, the importing agents typically place large, and therefore relatively few, orders within any six month period. Therefore, our sales to an importing agent can vary substantially from quarter to quarter depending on the size and timing of the orders, which has in the past and may in the future cause our quarterly results to fluctuate. We rely on six importers to supply substantially all of our product in China. Because we use a small number of importing agents in China, our

16

receivables from any one importing agent are material, and if we were unable to collect receivables from any importer, our business and cash-flow would be adversely affected.

If we fail to protect our products, technologies and trade secrets, we may not be able to successfully use, manufacture, market or sell our products, or we may fail to advance or maintain our competitive position.

     Our success depends significantly on our ability to obtain and maintain meaningful patent protection for our products and technologies and to preserve our trade secrets. Our pending patent applications may not result in the issuance of patents in the future. Our patents or patent applications may not have priority over others’ applications. Our existing patents and additional patents that may be issued, if any, may not provide a competitive advantage to us or may be invalidated or circumvented by our competitors. Others may independently develop similar products or design around patents issued or licensed to us. Patents issued to, or patent applications filed by, other companies could harm our ability to use, manufacture, market or sell our products or maintain our competitive position with respect to our products. Although many of our patents relating to ZADAXIN have expired, including composition of matter patents, we have rights to other patents and patent applications relating to ZADAXIN and ZADAXIN analogues, including method of use patents with respect to the use of ZADAXIN for certain indications. If other parties develop generic forms of ZADAXIN for other indications, including conducting clinical trials for such indications, our patents and other rights might not be sufficient to prohibit them from marketing and selling such generic forms of ZADAXIN. If other parties develop analogues or derivatives of ZADAXIN, our patents and other rights might not be sufficient to prohibit them from marketing these analogues or derivatives.

     Pharmaceutical products are either not patentable or have only recently become patentable in some of the countries in which we market or may market ZADAXIN. Past enforcement of intellectual property rights in many of these countries, including China in particular, has been limited or non-existent. Future enforcement of patents and proprietary rights in many other countries will likely be problematic or unpredictable. We are aware that other companies are marketing generic thymosin alpha 1 in China, possibly in violation of our trademark or other rights, and we expect such violations of our rights to continue. Moreover, the issuance of a patent in one country does not assure the issuance of a similar patent in another country. Claim interpretation and infringement laws vary by nation, so the extent of any patent protection is uncertain and may vary in different jurisdictions.

If we are involved in intellectual property claims and litigation, the proceedings may divert our resources and subject us to significant liability for damages, substantial litigation expense and the loss of our proprietary rights.

     Our commercial success depends in part on us not infringing valid, enforceable patents or proprietary rights of third parties, and not breaching any licenses that may relate to our technologies and products. We are aware of a third-party patent that may relate to our products and may cover a method of action used by ZADAXIN. We cannot assure you that our mechanism of action does not infringe on their claim. In addition, we may not be aware of all patents or patent applications that may impact our ability to make, use or sell any of our potential products. For example, U.S. patent applications may be kept confidential for up to 18 months while pending in the Patent and Trademark Office, and patent applications filed in foreign countries are often first published six months or more after filing. It is possible that we may unintentionally infringe these patents or other patents or proprietary rights of third parties. We may in the future receive notices claiming infringement from third parties as well as invitations to take licenses under third-party patents. Any legal action against us or our collaborative partners claiming damages and seeking to enjoin commercial activities relating to our products and processes affected by third-party rights may require us or our collaborative partners to obtain licenses in order to continue to manufacture or market the affected products and processes. Our efforts to defend against any of these claims, regardless of merit, would require us to devote resources and attention that could have been directed to our operations and growth plans. In addition, these actions may

17

subject us to potential liability for damages. We or our collaborative partners may not prevail in a patent action and any license required under a patent may not be made available on commercially acceptable terms, or at all. Any conflicts resulting from the patent rights of others could significantly reduce the coverage of our patents and limit our ability to obtain meaningful patent protection.

     If other companies obtain patents with conflicting claims, we may be required to obtain licenses to those patents or develop or obtain alternative technology to manufacture or market the affected products and processes. We may not be able to obtain any such licenses on acceptable terms or at all. Any failure to obtain such licenses could delay or prevent us from pursuing the development or commercialization of our potential products. Our efforts to defend against any of these claims would require us to devote resources and attention that could have been directed to our operations and growth plans.

     We may need to initiate litigation, which could be time-consuming and expensive, to enforce our proprietary rights or to determine the scope and validity of others’ rights. If litigation results, a court may find our patents or those of our licensors invalid or may find that we have infringed on a competitor’s rights. If any of our competitors have filed patent applications in the United States which claim technology we also have invented, the Patent and Trademark Office may require us to participate in expensive interference proceedings to determine who has the right to a patent for the technology. These actions may subject us to potential liability for damages. We or our collaborative partners may not prevail in a patent action and any license required under a patent may not be made available on commercially acceptable terms, or at all.

We rely on third parties to supply our clinical trial and commercial products. Deficiencies in their work could delay or harm one or more important areas of our business including our sales, clinical trials or the regulatory approval process.

     We rely on third parties, who are subject to regulatory oversight, to supply our clinical and commercial products. Typically we have at any time only one supplier for each phase of manufacturing of our product. If unanticipated deficiencies in these suppliers occur, we could experience delays in our ability to assemble a timely and acceptable NDA. If sales of ZADAXIN were to increase dramatically, our third-party suppliers may not be able to supply ZADAXIN quickly enough, which could limit our ability to satisfy increased demand or could adversely affect the ability of these suppliers to provide products for our clinical trials. Not all of the ZADAXIN planned to be used in our HCV clinical trials has been manufactured and received. Roche is our exclusive supplier of pegylated interferon alpha for our current U.S. clinical trials, and we have not received all the pegylated interferon to be used in the clinical trials. Roche’s agreement with us to provide our supply of pegylated interferon alpha can be terminated by them without cause on 30-days’ notice, in which case we would need to purchase their product for use in the clinical trials. Any delay in receiving, or a recall of, pegylated interferon alpha or ZADAXIN, including by reason of Roche’s termination of its supply arrangement with us, could delay the clinical trials or detract from the integrity of the trial data. If any of the foregoing occurs, our ability to complete our clinical trials in the United States and to market and sell ZADAXIN worldwide will be delayed or impaired, our business will suffer and the price of our stock may decline. We have been in the process of qualifying a new manufacturer of ZADAXIN and if we encounter problems with this process of validation, our sales or our clinical trials could be adversely affected.

If we are not able to establish and maintain adequate manufacturing relationships, the development and sale of our products could be impaired.

     To be successful, our products must be manufactured in commercial quantities, in compliance with stringent regulatory requirements and at an acceptable cost. Typically we have at any time only one supplier for each phase of manufacturing of our product. Manufacturing interruptions or failure to comply with regulatory requirements could significantly delay clinical development of potential products and reduce third-party or clinical researcher interest and support of proposed trials. These interruptions or failures could also

18

impede commercialization of our products, including sales of ZADAXIN in approved markets, and impair our competitive position. Any of these developments would harm our business.

     We are in the process of changing suppliers for ZADAXIN and such changes require qualification of the new suppliers with regulatory agencies, quality assurance and other steps which could cause delays or interruptions of supply. If we do not obtain the required regulatory approvals for a manufacturing change in a timely fashion, especially in China, our sales may be interrupted until the manufacturing change is approved. Although we are increasing inventories to prepare to manage any such occurrences, we may still experience interruptions in supply which could adversely affect our results.

     In some countries, a manufacturing change may require additional regulatory approvals which may delay ZADAXIN marketing approvals in new markets.

     In addition, manufacturing, supply and quality control problems may arise as we, either alone or with subcontractors, attempt to scale-up our manufacturing procedures. We may not be able to scale-up in a timely manner or at a commercially reasonable cost, either of which could cause delays or pose a threat to the ultimate commercialization of our products and harm our business.

We may not be able to successfully develop or commercialize our products.

     While we have limited sales of ZADAXIN in certain markets, we do not yet have regulatory approval for ZADAXIN for our principal target markets, and, in this respect, ZADAXIN is still being developed. Our other potential products are in earlier stages of development than ZADAXIN. To fully develop our products, we will need to commit substantial resources to extensive research, development, pre-clinical testing, clinical trials, manufacturing scale-up and regulatory approval prior to being ready for sale. We cannot assure that our efforts will produce commercially viable products. We face significant technological risks inherent in developing these products. We may also abandon some or all of our proposed products before they become commercially viable. If any of our products, even if developed and approved, cannot be successfully commercialized in a timely manner, our business will be harmed and the price of our stock may decline.

     We have not yet sold any product other than ZADAXIN and our sales have been primarily in a single country, China. Our future revenue growth depends on increased market acceptance and commercialization of ZADAXIN in additional countries, particularly in the United States, Europe and Japan. If we fail to successfully market ZADAXIN, or if we cannot commercialize this drug in the United States and other additional markets, our revenue and operating results will suffer. If unexpected and serious adverse events are reported, or if expected efficacy results are not achieved, it would have a material adverse effect on our business. Our future revenue will also depend in part on our ability to develop other commercially viable and accepted products. Market acceptance of our products will depend on many factors, including our ability to convince prospective customers to use our products as an alternative to other treatments and therapies and to convince prospective strategic partners to market our products effectively and to manufacture our products in sufficient quantities with acceptable quality and at an acceptable cost. In addition, doctors must opt to use treatments involving our products. If doctors elect to use a different course of treatment, demand for our drug products would be reduced. Failure to do any of the above will hurt our operations.

We rely on third-party clinical investigators to conduct our clinical trials and, as a result, we may encounter delays outside our control.

     We have limited experience in conducting and managing clinical trials and we rely, in part, on third parties, particularly clinical research organizations and our development partners, to assist us in managing

19

and monitoring clinical trials. Our reliance on these third parties may result in delays in completing, or failure to complete, these clinical trials if third parties fail to fulfill their obligations to us.

We may need to obtain additional capital to support our long-term product development and commercialization programs.

     We believe our existing resources will be sufficient to complete our current U.S. phase 3 clinical trials and, if the trials are successful and we receive FDA approval, to begin commercialization of ZADAXIN in the United States. However, we cannot assure that such funds will be sufficient, or that sales of ZADAXIN, if approved in the United States, will result in profitable operations. In addition, we may need additional funds in the future to support future growth and achieve profitability. If we need to raise additional funds in the future and such funds are not available on reasonable terms, if at all, our commercialization efforts may be impeded, our revenues may be limited and our operating results may suffer.

We have a history of operating losses and an accumulated deficit. We expect to continue to incur losses in the near term and may never achieve profitability.

     We have experienced significant operating losses since our inception, and as of March 31, 2004, we had an accumulated deficit of approximately $141 million. We expect our operating expenses to increase over the next several years as we plan to dedicate substantially all of our resources to expanding our development, testing and marketing capabilities, particularly in the United States, and these losses may increase if we cannot increase or sustain revenue. As a result, we may never achieve profitability.

We have limited sales, marketing and distribution capabilities, which may adversely affect our ability to successfully commercialize our products.

     We currently have limited sales, marketing and distribution capabilities, and we anticipate that we may be relying on third-party collaborators to sell, market and distribute our products for the foreseeable future. If our arrangements with these third parties are not successful, or if we are unable to enter into additional third-party arrangements, we may need to substantially expand our sales, marketing and distribution force. Our efforts to expand may not succeed, or we may lack sufficient resources to expand in a timely manner, either of which will harm our operating results. Moreover, if we are able to further expand our sales, marketing and distribution capabilities, we will begin competing with other companies that have experienced and well-funded operations. If we cannot successfully compete with these larger companies, our revenues may not grow and our business may suffer.

Commercialization of some of our products depends on collaborations with others. If our collaborators are not successful, or if we are unable to find future collaborators, we may not be able to properly develop and commercialize our products.

     We depend in part on our distributors and business partners to develop and/or promote our drugs, and if they are not successful in their efforts or fail to do so, our business will suffer. For example, Sigma-Tau is responsible for the development and marketing of ZADAXIN in Europe. We generally do not have control over the amount and timing of resources that our business partners devote to ZADAXIN, and they have not always performed as or when expected. If they do not perform their obligations as we expect, particularly obligations regarding clinical trials, our development expenses would increase and the development and/or sale of our products could be limited or delayed, which could hurt our business and cause our stock price to decline. In addition, our relationships with these companies may not be successful. Disputes may arise with our collaborators, including disputes over ownership rights to intellectual property, know-how or technologies

20

developed with our collaborators. We may not be able to negotiate similar additional arrangements in the future to develop and commercialize ZADAXIN or other products.

We may lose market share or otherwise fail to compete effectively in the intensely competitive biopharmaceutical industry.

     Competition in the biopharmaceutical industry is intense, and we expect that competition will increase. Our success depends on our ability to compete in this industry, but we cannot assure you that we will be able to successfully compete with our competitors. Increased competitive pressure could lead to intensified price-based competition resulting in lower prices and margins, which would hurt our operating results.

     We are focused on developing ZADAXIN as a treatment for HCV and HBV and certain cancers. Several large biopharmaceutical companies have substantial commitments to interferon alpha, an approved drug for treating HBV and HCV, and to lamivudine and adefovir, approved drugs to treat HBV. We cannot assure you that we will compete successfully against our competitors or that our competitors, or potential competitors, will not develop drugs or other treatments for HCV, HBV, cancer and other diseases that will be superior to ours.

If third-party reimbursement is not available or patients cannot otherwise pay for ZADAXIN, we may not be able to successfully market ZADAXIN.

     Significant uncertainty exists as to the reimbursement status of new therapeutic products, such as ZADAXIN. We cannot assure you that third-party insurance coverage and reimbursement will be available for therapeutic products we might develop. The failure to obtain third-party reimbursement for our products, particularly in the United States, Europe and Japan, would harm our business. Further, we cannot assure you that additional limitations will not be imposed in the future in the United States on drug coverage and reimbursement due to proposed health care reforms. In many emerging markets where we have marketing rights to ZADAXIN, but where government resources and per capita income may be so low that our products will be prohibitively expensive, we may not be able to market our products on economically favorable terms, if at all.

     Efforts by governmental and third-party payors to contain or reduce health care costs or the announcement of legislative proposals or reforms to implement government controls could cause us to reduce the prices at which we market our drugs, which will reduce our gross margins and may harm our business.

If we lose key personnel or are unable to attract and retain additional, highly skilled personnel required for the expansion of our activities, our business will suffer.

     We are highly dependent upon our ability to attract and retain qualified personnel because of the specialized, scientific and worldwide nature of our business. There is intense competition for qualified management, scientific and technical personnel in the pharmaceutical industry, and we may not be able to attract and retain the qualified personnel we need to grow and develop our business globally. In addition, we assign numerous key responsibilities to a limited number of individuals, and we would experience difficulty in finding immediate replacements for any of them. If we were unable to attract and retain qualified personnel as needed or promptly replace those employees who are critical to our product development and commercialization, the development and commercialization of our products would be adversely affected. At this time, we do not maintain “key person” life insurance on any of our key personnel.

We may be subject to product liability lawsuits, and our insurance may be inadequate to cover damages.

21

     Clinical trials or marketing of any of our current and potential products may expose us to liability claims from the use of these products. We currently carry product liability insurance. However, we cannot be certain that we will be able to maintain insurance on acceptable terms, if at all, for clinical and commercial activities or that the insurance would be sufficient to cover any potential product liability claim or recall. If we fail to have sufficient coverage, our business, results of operations and cash flows could be adversely affected.

We depend on international sales, and global conditions could negatively affect our operating results.

     A large majority of our sales are in China. Heightened tensions resulting from the current geopolitical conditions in the Middle East, North Korea and elsewhere could worsen, causing disruptions in foreign trade, which would harm our sales. In particular, our commercial product is manufactured in Europe and distributed by us from our operations in Hong Kong. Any disruption of our supply and distribution activities due to geopolitical conditions could decrease our sales and harm our operating results.

If we are unable to comply with environmental and other laws and regulations, our business may be harmed.

     We are subject to various federal, state and local laws, regulations and recommendations relating to the use, manufacture, storage, handling and disposal of hazardous materials and waste products (including radioactive compounds and infectious disease agents), as well as safe working conditions, laboratory and manufacturing practices and the experimental use of animals. The extent of government regulation that might result from future legislation or administrative action in these areas cannot be accurately predicted.

     We do not currently maintain hazardous materials at our facilities. While we outsource our research and development programs involving the controlled use of biohazardous materials, if in the future we conduct these programs ourselves, we might be required to incur significant cost to comply with the environmental laws and regulations. Further, in the event of an accident, we would be liable for any damages that result, and the liability could exceed our resources.

Our stock price may be volatile, and an investment in our stock could suffer a decline in value.

     The market price of our common stock has experienced, and may continue to experience, substantial volatility due to many factors, some of which we have no control over, including:

•

progress and results of clinical trials involving ZADAXIN;

•

progress of ZADAXIN through the regulatory process, especially regulatory actions in the United States, Europe and Japan;

•

timing and achievement of milestones;

•

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

•

government regulatory action affecting our drug products or our competitors’ drug products in both the United States and foreign countries;

•

developments or disputes concerning patent or proprietary rights;

•

changes in company assessments or financial estimates by securities analysts;

22

•

actual or anticipated fluctuations in our quarterly operating results;

•

general stock market conditions and fluctuations for the emerging growth and biopharmaceutical market sectors;

•

economic conditions in the United States or abroad; and

•

broad financial market fluctuations in the United States, Europe or Asia.

     In the past, following periods of large price declines in the public market price of a company’s securities, securities class action litigation has often been initiated against that company. Litigation of this type could result in substantial costs and diversion of our attention and resources, which would hurt our business. Any adverse determination in litigation could also subject us to significant liabilities.

Substantial sales of our stock or the exercise or conversion of options or convertible securities may impact the market price of our common stock.

     As of March 31, 2004, stock options to purchase 5,894,021 shares of common stock were outstanding, of which options to purchase 4,078,297 shares were exercisable. Also outstanding as of the same date were warrants exercisable for 904,760 shares of common stock at $7.00 per share and two notes convertible into a total of 684,140 shares of common stock. The note holder has the right to purchase up to $8.3 million of additional convertible notes due on or before March 2006, which, if fully issued, will be convertible into 684,140 shares of our common stock. Upon exercise of options or warrants, or conversion of the notes, these issued shares of common stock will be freely tradable.

     Future sales of substantial amounts of our common stock could adversely affect the market price of our common stock. Similarly, if we raise additional funds through the issuance of common stock or securities convertible into or exercisable for common stock, the percentage ownership of our stockholders will be reduced and the price of our common stock may fall.

Sales of our common stock by officers and directors could affect our stock price.

     Our Board of Directors has approved an amendment to our trading policy that permits officers and directors to enter into trading plans that comply with the requirements of Rule 10b5-1 of the Securities and Exchange Act of 1934. Rule 10b5-1 allows corporate officers and directors to adopt written, pre-arranged stock trading plans when they do not have material, non-public information. Using these plans, officers and directors can gradually diversify their investment portfolios, can spread stock trades out over an extended period of time to reduce any market impact and can avoid concerns about initiating stock transactions at a time when they might be in possession of material, non-public information. As of April 28, 2004, only one director has adopted such a plan, with sales commencing no earlier than May 2004, and other directors or officers may do so in the future. In general our officers and directors have rarely sold stock in the Company, though they have held options or stock for many years. We expect future sales by officers and directors either under 10b5-1 plans or otherwise as result of personal financial planning. We do not believe the volume of such sales would affect our trading price, however, the market could react negatively to sales by our officers and directors, affecting the trading price of our stock.

If our officers, directors and largest stockholders elect to act together, they may be able to control our management and operations, acting in their best interests and not necessarily those of other stockholders.

     As of March 31, 2004 our directors and officers owned or had the right to acquire approximately 7.7% of the outstanding shares of our common stock. Our two largest stockholders, Sigma-Tau (and its

23

affiliates) and Randal J. Kirk, owned in the aggregate approximately 12.9% of the outstanding shares of our capital stock. As a result, due to their concentration of stock ownership, our directors, officers and largest stockholders, if they act together, may be able to influence our management and operation and may be able to affect or influence all matters requiring a stockholder vote, including the election of all directors and the amendment of charter documents or the approval of a merger, sale of assets or other major corporate transactions.

     Although they are independent of each other and not part of a group, in 2003 we obtained the support of Sigma-Tau and Mr. Kirk for our proposal to the stockholders to reincorporate in Delaware, and without that support we would not have been able to obtain the required stockholder approval for that matter.

Anti-takeover provisions in our charter documents and under Delaware law may make an acquisition of us, which may be beneficial to our stockholders, more difficult.

     Certain anti-takeover provisions of Delaware law and our charter documents as currently in effect may make a change in control of our company more difficult, even if a change in control would be beneficial to the stockholders. Prior to our recent reincorporation in Delaware, we had a stockholder rights plan, also commonly known as a “poison pill,” which we terminated in connection with the reincorporation. We currently do not intend to adopt a stockholder rights plan. However, our charter documents do contain certain anti-takeover provisions, including provisions in our certificate of incorporation providing that stockholders may not cumulate votes, stockholders’ meetings may be called by stockholders only if they hold 25% or more of our common stock and provisions in our bylaws providing that the stockholders may not take action by written consent. Additionally, our board of directors has the authority to issue 10 million shares of preferred stock and to determine the terms of those shares of stock without any further action by the stockholders. The rights of holders of our common stock are subject to the rights of the holders of any preferred stock that may be issued. The issuance of preferred stock could make it more difficult for a third-party to acquire a majority of our outstanding voting stock. Delaware law also prohibits corporations from engaging in a business combination with any holders of 15% or more of their capital stock until the holder has held the stock for three years unless, among other possibilities, the board of directors approves the transaction. Our board of directors may use these provisions to prevent changes in the management and control of our company. Also, under applicable Delaware law, our board of directors may adopt additional anti-takeover measures in the future.

We may be subject to currency exchange rate fluctuations, which could adversely affect our financial performance.

     Substantially all of our product sales are denominated in U.S. dollars. Fluctuation in the U.S. dollar exchange rate with local currency directly affects the customer’s cost for our product. In particular, a stronger U.S. dollar vis-à-vis the local currency would tend to have an adverse effect on sales and potentially on collection of accounts receivable. To date, this exposure to currency exchange rate fluctuations has been minimal because the Chinese currency has been pegged to the U.S. dollar. However, the fixed nature of the Chinese currency in relation to the U.S. dollar may not continue in the future and, consequently, our foreign operations may expose us to greater risk of currency exchange rate fluctuations in the future. In addition, we are subject to currency exchange rate fluctuations as a result of expenses incurred by our foreign operations. In particular, one of our supply arrangements under which we purchase finished products is denominated in euros. Consequently, changes in exchange rates could unpredictably and adversely affect our operating results and could result in exchange losses. To date, we have not hedged against the risks associated with fluctuations in exchange rates and, therefore, exchange rate fluctuations could have a material adverse impact on our operating results and stock price.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

     The primary objective of our investment activities is to preserve principal while at the same time maximizing yields without significantly increasing risk. To achieve this objective, we invest solely in U.S. Treasury or U.S. government agency notes. Our investments in these notes are subject to interest rate risk. To minimize the exposure due to an adverse shift in interest rates, we invest in short-term notes and maintain an average maturity of less than one year. A hypothetical 60 basis point increase in interest rates would result in an approximate $193,525 decrease (0.6%) in fair value of our available-for-sale securities. This potential change is based on sensitivity analyses performed on our financial position at March 31, 2004. Actual results may differ materially.

     Substantially all our sales and most of our manufacturing costs to date have been in U.S. dollars. Our purchases from one of our contract manufacturers are denominated in euros and this exposes us to foreign currency rate fluctuations.

Item 4. Controls and Procedures

     Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we evaluated the effectiveness of our disclosure controls and procedures, as such term is defined in Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this quarterly report.
