See "Where You Can Find More Information" on page S-21. OUR BUSINESS Novavax is a fully-integrated specialty pharmaceutical company focused on the research, development and commercialization of products utilizing our proprietary drug delivery and vaccine technologies for large and growing markets, concentrating on the areas of women's health and infectious diseases. On October 9, 2003, the U.S. Food and Drug Administration approved ESTRASORB(TM), our estradiol topical emulsion and the first topical emulsion for estrogen replacement therapy, for for short-term use to reduce moderate to severe vasomotor symptoms - commonly known as "hot flashes" - in menopausal women. We will co-promote ESTRASORB with King in the United States and Puerto Rico under the co-promotion agreement discussed below and expect to launch ESTRASORB in early 2004 utilizing a combined sales force that is estimated to be comprised of approximately 150 individuals at the time of launch. We believe ESTRASORB will be competitively positioned to address the estrogen-only replacement therapy market in the United States, which is estimated to be in excess of $1.5 billion. Our micellar nanoparticle technology involves the use of our patented oil and water emulsions that we believe can be used as vehicles for the topical delivery of a wide variety of drugs and other therapeutic products, including hormones. We believe that our technology represents the first time that ethanol soluble hormones, such as estrogen and testosterone, have been encapsulated and delivered topically. In addition to ESTRASORB(TM), our product candidates using these technologies include ANDROSORB(TM), a topical testosterone emulsion that has completed two Phase I clinical trials; a topical estrogen and testosterone emulsion; a topical progestin emulsion; and a topical estrogen and progestin emulsion. We are utilizing other drug delivery technologies, such as our Novasome(R) and Sterisome(R) technologies, in order to develop other products. Novasomes are used as adjuvants to enhance vaccine effectiveness. Sterisomes are being used for, among other things, subcutaneous injections that can deliver long-acting drug effects. We also conduct research and development on preventative vaccines and proteins for a variety of infectious diseases and immunotherapies. Over the past three years we have entered into a co-promotion agreement with King Pharmaceuticals, Inc. for the promotion and marketing of ESTRASORB and ANDROSORB (if approved) within the United States and Puerto Rico, and we have licensed to King the right to sell these products outside the United States. Our relationship with King has the potential to provide us with broader women's health market coverage for ESTRASORB and ANDROSORB. Under the terms of our co-promotion agreement with King, we will record all of the product sales, returns and allowances, and cost of sales for ESTRASORB and ANDROSORB (if approved) in the United States and Puerto Rico. The resultant gross margin will be shared equally with King and the payment to King will be recorded as a selling and marketing expense on our statement of operations. In addition, under the agreement both parties will also share equally in approved marketing expenses for the products. All direct marketing expenses will be recorded by us, 50% of which will be reimbursed by King. We received licensing fees of $3.0 million and milestone payments totaling $5.0 million from King upon the submission to the FDA and acceptance for review of the ESTRASORB New Drug Application. We have also received from King $20.0 million in December 2000, $10.0 million in September 2001 and $10.0 million in June 2002, in the form of convertible note financings. We currently market, sell and distribute a line of prescription pharmaceuticals through our 65 person sales force that has extensive experience selling to obstetricians, gynecologists, managed care organizations, wholesalers and retail pharmacies throughout the United States. In 2002, these products generated revenues of $12.8 million. We expect to sell ESTRASORB through both our sales force and King's sales force. We intend to manufacture ESTRASORB for commercial sale in our dedicated, state-of-the-art, 24,000 square foot facility in Philadelphia, Pennsylvania. S-3 RECENT DEVELOPMENTS On August 8, 2003, we announced that Nelson M. Sims, a 28-year veteran of Eli Lilly and Company, had been named President and Chief Executive Officer of our company, succeeding Mitchell J. Kelly, who had served as President and Chief Executive Officer since September 2002. Mr. Sims retired from Eli Lilly and Company in 2001 following 28 years of service, during which he held numerous executive management positions, including President of Eli Lilly Canada, Inc., Executive Director Strategic Alliance Management, Vice President Hybritech, Inc. (a Lilly subsidiary) and U.S. Eastern Region Pharmaceutical Sales Director. On September 29, 2003, we announced that we had been awarded a five year, $19.0 million contract from the National Institute of Allergy and Infectious Diseases for the design and development of a new class of human immunodeficiency virus vaccine candidates for preclinical and clinical studies. We will serve as prime contractor, with Emory University, Tulane University and the University of Pittsburgh as sub-contractors, and we expect to receive approximately $14.0 million over the five-year contract term. This contract is the second award in two months that we received for our HIV vaccine development program. In August 2003, we were part of a consortium that received a NIAID project program grant to develop another set of HIV vaccine candidates. We expect to receive approximately $4.0 million over 4 1/2 years for our participation in the grant effort. As noted above, ESTRASORB, our estradiol topical emulsion for estrogen replacement therapy that utilizes a topical formulation developed by the Company, was approved on October 9,, 2003 by the FDA for short-term use to reduce moderate to severe vasomotor systems - commonly known as "hot flashes" - in menopausal women. In an effort to streamline and consolidate operations, we have decided to close our St. Louis, Missouri packaging, warehouse and distribution facility for our current women's health products, in December, 2003. We will transition the operations conducted at this facility to our headquarters in Maryland and to other third-party service providers. We do not expect to incur significant additional costs, or experience any distribution delays, related to this transition. Our principal executive offices are located at 8320 Guilford Road, Columbia, MD 21046. Our telephone number is (301) 854-3900. We are incorporated under the laws of the State of Delaware.

Some of the following risks relate principally to our business and the industry in which we operate. Other risks relate principally to the securities market and ownership of our common stock. If any of the following risks occur, our business, financial condition and/or operating results could be adversely affected. In that case, the trading price of our common stock could decline, and you could lose all or part of your investment. OUR SUCCESS IS HEAVILY DEPENDENT ON MARKET ACCEPTANCE OF ESTRASORB. ESTRASORB was approved by the FDA on October 9, 2003. Even with ESTRASORB's approval by the FDA, there is no guarantee either that we and King Pharmaceuticals, Inc., our marketing partner for ESTRASORB, will be able to successfully commercialize ESTRASORB, or that ESTRASORB will be a commercial success. Many factors could negatively affect our ability to successfully commercialize ESTRASORB, including: - delays in the manufacture and validation of ESTRASORB in commercial quantities; - our inability to timely and effectively promote and sell ESTRASORB with King in the United States and Puerto Rico or by King outside those regions, so that ESTRASORB gains a meaningful share of the estrogen replacement therapy market, which currently is dominated by Premarin(R), an oral estrogen tablet sold by Wyeth, and estrogen patches sold by several companies including Novartis Pharma AG, Berlex Laboratories, Inc. and Forest Pharmaceuticals, Inc.; - our inability to manufacture ESTRASORB at acceptable gross margins; and - our inability to obtain coverage and favorable reimbursement rates for ESTRASORB from insurers and other third party payors. WE WILL FACE SUBSTANTIAL COMPETITION IN CONNECTION WITH THE SALE OF ESTRASORB AND OUR OTHER PRODUCT CANDIDATES. We compete with numerous other companies worldwide that have developed or are developing products that compete or may compete with ESTRASORB and our product candidates. These competitors include both large and small pharmaceutical companies, biotechnology firms, universities and other research institutions. We may not succeed in developing technologies and products that are more effective than those being developed by our competitors. Many large companies currently produce and sell estrogen products for clinical indications identical to those for ESTRASORB. In the oral product segment of the estrogen replacement therapy market, which accounts for approximately 74% of the market according to 2002 IMS Health Incorporated data, Wyeth commits significant resources to the sale and marketing of its product, Premarin(R), in order to maintain its market leadership position. Warner-Chillcot also competes in the branded oral product segment with its product, Estrace(R). In addition, ESTRASORB will compete with products produced and sold by generic manufacturers in the oral product segment of the market, such as Watson Pharmaceutical, Inc.'s generic product, Estropipate(R). In the patch segment of the market, which according to IMS Health accounts for approximately 15% of the estrogen replacement therapy market, several companies market transdermal estrogen patches with which ESTRASORB will compete. For example, Novartis Pharma AG currently markets and sells its Vivelle(R) and Estraderm(R) patches and Berlex Laboratories, Inc. and Forest Pharmaceuticals Inc. co-promote the Climara(R) transdermal patch. Several companies also currently market ethanol-based estrogen gels and ointments outside the United States. For example, Schering Canada sells its estrogen gel, Estrogel(R), in Canada. These and other products sold by our competitors have all achieved some degree of market penetration. ESTRASORB will compete in the United States for market share with these products and we cannot guarantee that, together with King, we will be able to effectively promote ESTRASORB against these competitive products. In order to effectively compete, we will make substantial investments in sales and marketing. Many of these products are sold by companies with greater resources than we S-7 have and there is no assurance that we will be successful in gaining significant market share for ESTRASORB or in earning a return on our investment in ESTRASORB or our other product candidates, if approved. Our technologies and products may be rendered obsolete or noncompetitive as a result of products introduced by competitors. Most of our competitors have substantially greater financial and technical resources, production and marketing capabilities, and related experience than we do. The greater resources, capabilities and experience of our competitors may enable them to develop, manufacture and market their products more successfully and at a lower cost than we can. In addition, many of our competitors have significantly greater experience than we do in conducting preclinical testing and clinical trials of human pharmaceuticals and obtaining regulatory approvals to market such products. Accordingly, our competitors may succeed in obtaining FDA approval for products more rapidly than we will, which may give them an advantage over us in achieving market acceptance of their products. WE ARE UNCERTAIN ABOUT OUR ABILITY TO OBTAIN FUTURE FINANCING. We cannot be certain that we will be able to generate revenues from product sales in the near term or at all sufficient to fund our operations, and we could require additional funds to continue our research and development programs, commence future preclinical and clinical trials, seek regulatory approvals, establish commercial-scale manufacturing capabilities, and market our products. We may seek additional funds through public or private equity or debt financings, collaborative arrangements with pharmaceutical companies, and other sources. We cannot be certain that adequate additional funding will be available to us on acceptable terms, if at all. If we cannot raise the additional funds we may need for our anticipated operations, we may be required to delay significantly, reduce the scope of, or eliminate one or more of, our research or development programs; downsize our selling, marketing, general and administrative infrastructure or programs; or seek alternative measures to avoid insolvency, including arrangements with collaborative partners or others that may require us to relinquish rights to certain of our technologies, product candidates or products. WE HAVE A HISTORY OF LOSSES AND OUR FUTURE PROFITABILITY IS UNCERTAIN. Our expenses have exceeded our revenues since our formation in 1987, and our accumulated deficit at September 30, 2003 was $101.7 million. Our revenues for the last three years were $15.0 million in 2002, $24.0 million in 2001 and $2.5 million in 2000. For the nine months ended September 30, 2003 and 2002, our revenues were $7.7 million and $12.5 million, respectively. Sales of products that we acquired as a result of our acquisition of Fielding Pharmaceutical Company in 2000 have generated modest revenues, but based on our current business plan these revenues will not be sufficient to offset our expenses in the future. We cannot be certain when or if we will generate substantial revenues from the sale of ESTRASORB. We have received a very limited amount of product-related revenue from research contracts, licenses and agreements to provide vaccine products, services and adjuvant technologies. We cannot be certain that we will be successful in entering into strategic alliances or collaborative arrangements with other companies that will result in other significant revenues to offset our expenses. Our net losses for the last three years were $22.7 million in 2002, $9.7 million in 2001 and $12.2 million in 2000, while they were $14.2 million and $18.4 million for the nine months ended September 30, 2003 and 2002, respectively. Our losses have resulted from research and development expenses, pre-launch sales and marketing expenses in the anticipation of FDA approval for ESTRASORB, protection of our intellectual property, and other general operating expenses. Our annual losses may increase depending on the timing of the launch of ESTRASORB as we expand our manufacturing capacity, sales and marketing capabilities and conduct additional and larger clinical trials for other product candidates. Therefore, we expect our cumulative operating loss to increase until such time, if ever, product sales, licensing fees and royalty payments generate sufficient revenue to fund our continuing operations. We cannot predict when, if ever, we might achieve profitability and cannot be certain that we will be able to sustain profitability, if achieved. We intend to allocate a significant portion of our sales force's time to the product launch of ESTRASORB. Accordingly, the sales of our other women's health products could be adversely affected by the efforts we allocate to the ESTRASORB product launch. The costs of maintaining our own sales force to market our current products and ESTRASORB may in the future exceed product revenues. If we continue to market ESTRASORB or future products directly, significant additional expenditures and management resources may be required to increase the size of our internal sales force. S-8 OUR SALES AND MARKETING PLAN FOR ESTRASORB DEPENDS IN LARGE PART ON THE SUCCESS OF OUR RELATIONSHIP WITH KING. We have entered into a co-promotion agreement with King for the marketing and promotion of ESTRASORB in the United States using our sales and marketing personnel and King's sales and marketing personnel. We have also granted King exclusive rights to promote, market and distribute ESTRASORB outside the United States. In return, we received certain milestone payments. We are entitled to receive additional payments upon the achievement of specified milestones and licensing fees and royalties on future sales. While our co-promotion and licensing agreements with King give us some limited protections with respect to King's marketing and sales efforts and, we believe, create financial incentives for King consistent with our own, we cannot control the amount and timing of the marketing efforts that King devotes to ESTRASORB, or make any assurances that co-promotion efforts by the Company and King of ESTRASORB in the United States, and King's marketing of ESTRASORB outside the United States, will be successful. Our success in marketing other potential future products will also depend in large part on our relationship with King. Our co-promotion agreement with King also provides for the co-promotion with King in the United States of our product candidate ANDROSORB(TM). If this product is approved for marketing by the FDA, King has an exclusive worldwide license, except in the United States, to market this product. Under our co-promotion agreement, King also has the right to co-promote certain future hormone replacement therapy products that we may develop in the field of women's health. In the future, we might enter into other licensing or co-promotion arrangements with King or other third parties for the marketing and sale of other future products. Assuming FDA approval, any revenues we receive from sales of ANDROSORB and other future products will depend in large part on the terms of these agreements and the efforts of King and any other third-party marketing partners. OUR AGREEMENTS WITH KING REDUCE THE LIKELIHOOD THAT WE COULD BE ACQUIRED BY ANOTHER COMPANY. Our co-promotion agreement and license agreement with King for the marketing of ESTRASORB and ANDROSORB contain several provisions that would take effect upon a change of control of the Company. One provision allows King several options in the event of a change in control of Novavax including (i) terminating our right to co-promote King products, (ii) terminating our rights to promote ESTRASORB and ANDROSORB (if approved) and certain other hormone therapies for women, or (iii) requiring Novavax to assign and transfer to King all related rights of ownership for ESTRASORB and ANDROSORB and certain other hormone replacement therapies for women and license to King on an exclusive and perpetual basis all intellectual property rights and know-how with respect to such products. If King chooses to exercise its rights under either clause (ii) or (iii) above, King will pay us royalties on net sales of such products. In addition, King will pay us for the cost of manufacturing, plus a markup consistent with the terms of the license agreement for handling costs. In the event of a change in control, King could also require that we redeem $40.0 million in aggregate principal amount of our outstanding convertible promissory notes that it currently holds, at a redemption price equal to 101% of the outstanding principal and accrued interest. These provisions may have the effect of making us less attractive as an acquisition candidate. WE NEED ADDITIONAL MANUFACTURING CAPABILITY TO COMMERCIALIZE OUR PRODUCTS. We do not have any experience with the large capacity manufacturing required for commercial sale of a product. Although we have had the ability to produce the limited quantities of products needed to support our current research and development programs and clinical trials (including utilizing contract manufacturing organizations), we will need more production capacity for larger, later-stage clinical studies and commercial sales. Our potential products may be too difficult or costly to manufacture on a large scale, to develop into commercially viable products, or to market. We have validated our manufacturing methods for ESTRASORB, which has been produced in 100-kilo size batches. Such validation is required under FDA guidelines, and we received FDA approval of these methods in connection with the approval of ESTRASORB. We currently manufacture ESTRASORB at a facility of Cardinal Health, Inc. in Philadelphia, Pennsylvania. We expect that Cardinal Health will provide packaging services for ESTRASORB that we manufacture in their facility. We have completed the build out of the facility to meet our requirements and have installed manufacturing equipment for commercial production of ESTRASORB. Now that S-9 this new equipment is installed, we need to validate that the ESTRASORB made using this new equipment is identical to that used in our clinical trials. If we are unable to make ESTRASORB on a commercial scale or are delayed in validating the product manufactured with our new equipment, the commercialization of ESTRASORB would be delayed. In the near term, we will be manufacturing ESTRASORB only in the Philadelphia facility. Now that ESTRASORB has been approved by the FDA, we may determine to qualify an additional site or sites for the manufacture of ESTRASORB as our production requirements increase. If we are unable to utilize the Philadelphia facility to manufacture ESTRASORB prior to our qualification of a second site, however, we would not have immediate access to ESTRASORB and would be required to reestablish our validation process at a different facility that would cause us to lose sales of ESTRASORB and would adversely affect our business. We currently utilize third-party contract manufacturers to manufacture our other products. Any contract manufacturer's facility that we may use, including the Cardinal Health facility, must adhere to the FDA's regulations on current good manufacturing practices, which are enforced by the FDA through its facilities inspection program. These facilities are subject to periodic inspection by the FDA. The manufacture of products at these facilities will be subject to strict quality control testing and record-keeping requirements. We may not be able to enter into alternative manufacturing arrangements at commercially acceptable rates, if at all. Moreover, the manufacturers we use may not provide sufficient quantities of product to meet our specifications or our delivery, cost and other requirements. If we decide to manufacture our own products, we will need to acquire additional manufacturing facilities and improve our manufacturing technology. Establishing additional manufacturing facilities will require us to spend substantial funds, hire and retain a significant number of additional personnel and comply with extensive regulations applicable to such facilities in the United States and abroad, including the current good laboratory practices and good manufacturing practices required by the FDA. If we elect or need to manufacture our own products, we risk the possibility that we may not be able to do so in a timely fashion at acceptable quality and prices or in compliance with good laboratory practices and good manufacturing practices. WE HAVE NOT COMPLETED THE DEVELOPMENT OF MANY OF OUR PRODUCTS AND WE MAY NOT SUCCEED IN OBTAINING THE FDA APPROVAL NECESSARY TO SELL ANY ADDITIONAL PRODUCTS. The development, manufacture and marketing of our pharmaceutical products are subject to government regulation in the United States and other countries. In the United States and most foreign countries, we must complete rigorous preclinical testing and extensive human clinical trials that demonstrate the safety and efficacy of a product in order to apply for regulatory approval to market the product. Only a few of our products have been approved for sale, including ESTRASORB. Our product candidate, ANDROSORB, has completed two Phase I human clinical studies. Our other product candidates are in preclinical laboratory or animal studies. Before applying for FDA approval to market any additional product candidates, we must conduct larger-scale Phase II and III human clinical trials that demonstrate the safety and efficacy of our products, including ANDROSORB, to the satisfaction of the FDA or other regulatory authorities. These processes are expensive and can take many years to complete, and we may not be able to demonstrate the safety and efficacy of our products to the satisfaction of the FDA or other regulatory authorities. We may also be required to demonstrate that our proposed products represent an improved form of treatment over existing therapies and we may be unable to do so without conducting further clinical studies. We may fail to obtain regulatory approval for our products on a timely basis. Delays in obtaining regulatory approval can be extremely costly in terms of lost sales opportunities and increased clinical trial costs. The speed with which we complete our clinical trials and our applications for marketing approval will depend on several factors, including the following: - the rate of patient enrollment, which is a function of many factors, including the size of the patient population, the proximity of patients to clinical sites, the eligibility criteria for the study and the nature of the protocol; S-10 - institutional review board approval of the protocol and the informed consent form; - prior regulatory agency review and approval; - analysis of data obtained from preclinical and clinical activities that are susceptible to varying interpretations, which interpretations could delay, limit or prevent regulatory approval; - changes in the policies of regulatory authorities for drug approval during the period of product development; and - the availability of skilled and experienced staff to conduct and monitor clinical studies and to prepare the appropriate regulatory applications. We have limited experience in conducting and managing the preclinical and clinical trials necessary to obtain regulatory marketing approvals. We may not be able to obtain the approvals necessary to conduct clinical studies. Also, the results of our clinical trials may not be consistent with the results obtained in preclinical studies or the results obtained in later phases of clinical trials may not be consistent with those obtained in earlier phases. A number of companies in the specialty pharmaceutical industry have suffered significant setbacks in advanced clinical trials, even after experiencing promising results in early animal and human testing. If regulatory approval of a drug is granted, such approval is likely to limit the indicated uses for which it may be marketed. Furthermore, even if a product of ours gains regulatory approval, the product and the manufacturer of the product will be subject to continuing regulatory review. We may be restricted or prohibited from marketing or manufacturing a product, even after obtaining product approval, if previously unknown problems with the product or its manufacture are subsequently discovered. OUR SUCCESS DEPENDS ON OUR ABILITY TO MAINTAIN THE PROPRIETARY NATURE OF OUR TECHNOLOGY. Our success will, in large part, depend on our ability to maintain the proprietary nature of our technology and other trade secrets. To do so, we must prosecute and maintain existing patents, obtain new patents and pursue trade secret protection. We also must operate without infringing the proprietary rights of third parties or letting third parties infringe our rights. We currently have 55 U.S. patents and approximately 150 foreign patents and patent applications covering our technologies. We recently filed eight new patent applications in the United States and worldwide directed towards innovative discoveries made in the field of human Papillomavirus virus-like particles. However, patent issues relating to pharmaceuticals involve complex legal, scientific and factual questions. To date, no consistent policy has emerged regarding the breadth of biotechnology patent claims that are granted by the U. S. Patent and Trademark Office or enforced by the federal courts. Therefore, we do not know whether our patent applications will result in the issuance of patents, or that any patents issued to us will provide us with any competitive advantage. We also cannot be sure that we will develop additional proprietary products that are patentable. Furthermore, there is a risk that others will independently develop or duplicate similar technology or products or circumvent the patents issued to us. There is a risk that third parties may challenge our existing patents or may claim that we are infringing their patents or proprietary rights. We could incur substantial costs in defending patent infringement suits or in filing suits against others to have their patents declared invalid or claim infringement. It is also possible that we may be required to obtain licenses from third parties to avoid infringing third-party patents or other proprietary rights. We cannot be sure that such third-party licenses would be available to us on acceptable terms, if at all. If we are unable to obtain required third-party licenses, we may be delayed in or prohibited from developing, manufacturing or selling products requiring such licenses. Although our patents include claims covering various features of our product candidates, including composition, methods of manufacture and use, our patents do not provide us with complete protection against the development of competing products. For example, our patents do not prohibit third parties from developing and selling products for estrogen replacement therapy that deliver estrogen through a topical emulsion, ointment or similar medium. S-11 Some of our know-how and technology is not patentable. To protect our proprietary rights in unpatentable intellectual property and trade secrets, we require employees, consultants, advisors and collaborators to enter into confidentiality agreements. These agreements may not provide meaningful protection for our trade secrets, know-how or other proprietary information in the event of any unauthorized use or disclosure. HEALTH CARE INSURERS AND OTHER PAYORS MAY NOT PAY FOR OUR PRODUCTS OR MAY IMPOSE LIMITS ON REIMBURSEMENT. Our ability to commercialize ESTRASORB and our future products will depend, in part, on the extent to which reimbursement for such products will be available from third-party payors, such as Medicare, Medicaid, health maintenance organizations, health insurers and other public and private payors. If we succeed in bringing ESTRASORB or other products in the future to market, we cannot be assured that third-party payors will pay for ESTRASORB or such products or will establish and maintain price levels sufficient for realization of an appropriate return on our investment in product development. For example, ESTRASORB will be sold as an outpatient prescription drug. Medicare does not cover the costs of most outpatient prescription drugs. We expect that ESTRASORB will be treated the same as other estrogen replacement therapy products with respect to government and third-party payor reimbursement. However, there can be no assurance that ESTRASORB will receive similar reimbursement treatment. Many health maintenance organizations and other third-party payors use formularies, or lists of drugs for which coverage is provided under a health care benefit plan, to control the costs of prescription drugs. Each payor that maintains a drug formulary makes its own determination as to whether a new drug will be added to the formulary and whether particular drugs in a therapeutic class will have preferred status over other drugs in the same class. This determination often involves an assessment of the clinical appropriateness of the drug and sometimes the cost of the drug in comparison to alternative products. There can be no assurance that ESTRASORB or any of our future products will be added to payors' formularies, that our products will have preferred status to alternative therapies, or that the formulary decisions will be conducted in a timely manner. We may also decide to enter into discount or formulary fee arrangements with payors, which could result in us receiving lower or discounted prices for ESTRASORB or future products. WE MAY HAVE PRODUCT LIABILITY EXPOSURE. The administration of drugs to humans, whether in clinical trials or after marketing clearances are obtained, can result in product liability claims. We maintain product liability insurance coverage in the total amount of $18.0 million for claims arising from the use of our currently marketed products and products in clinical trials prior to FDA approval. Coverage is becoming increasingly expensive, however, and we may not be able to maintain insurance at a reasonable cost. There can be no assurance that we will be able to maintain our existing insurance coverage or obtain coverage for the use of our other products in the future. This insurance coverage and our resources may not be sufficient to satisfy liabilities resulting from product liability claims. A successful claim may prevent us from obtaining adequate product liability insurance in the future on commercially desirable terms, if at all. Even if a claim is not successful, defending such a claim may be time-consuming and expensive, may damage our reputation in the marketplace, and may divert management's attention. WE HAVE MADE LOANS TO CERTAIN OF OUR DIRECTORS, AND HAVE GUARANTEED A BROKERAGE MARGIN LOAN FOR ONE OF THESE DIRECTORS THAT COULD HAVE A NEGATIVE IMPACT ON OUR STOCK PRICE. In 2002, pursuant to our Stock Option Plan, we approved the payment of the exercise price of options by two of our directors through the delivery of full-recourse, interest-bearing promissory notes, in the aggregate principal amount of approximately $1.5 million, secured by a pledge of the underlying shares. In addition, in 2002 we executed a conditional guaranty of a brokerage margin account for a director in the amount of $500,000. Due to heightened sensitivity in the current environment surrounding related party transactions, these transactions could be viewed negatively in the market and our stock price could be negatively affected. S-12 THE PRICE OF OUR COMMON STOCK HAS BEEN, AND MAY CONTINUE TO BE, VOLATILE. Historically, the market price of our common stock has fluctuated over a wide range. In fiscal 2002, our common stock traded in a range from a low of $1.59 to a high of $14.00. Between January 1, 2003 and November 12, 2003, our common stock has traded in a range from a low of $2.52 to a high of $ 8.62. It is likely that the price of our common stock will fluctuate in the future. The market prices of securities of small-capitalization, specialty pharmaceutical companies, including ours, from time to time experience significant price and volume fluctuations unrelated to the operating performance of these companies. In particular, the market price of our common stock may fluctuate significantly due to a variety of factors, including: - governmental agency actions, including the FDA's determination with respect to NDAs for new products; - our ability to obtain financing; and - sales of our products, particularly ESTRASORB. In addition, the occurrence of any of the risks described in this "Risk Factors" section could have a material and adverse impact on the market price of our common stock. OUR SUBSTANTIAL INDEBTEDNESS COULD ADVERSELY AFFECT OUR CASH FLOW AND PREVENT US FROM FULFILLING OUR OBLIGATIONS. We currently have $41.5 million of outstanding indebtedness. Our substantial amount of outstanding indebtedness could have significant consequences. For example, it: - could increase our vulnerability to general adverse economic and industry conditions; - will require us to dedicate a substantial portion of our cash flow from operations to service payments on our indebtedness, reducing the availability of our cash flow to fund future capital expenditures, working capital, execution of our growth strategy, research and development costs and other general corporate requirements; - could limit our flexibility in planning for, or reacting to, changes in our business and the pharmaceutical industry, which may place us at a competitive disadvantage compared with competitors that have less indebtedness; and - could limit our ability to borrow additional funds, even when necessary to maintain adequate liquidity. We may incur additional indebtedness for various reasons, which, if in excess of a certain amount, must be approved by King. Any such additional indebtedness would increase the risks associated with our substantial leverage. OUR INABILITY TO RECRUIT AND RETAIN MEMBERS OF OUR MANAGEMENT TEAM AND KEY PERSONNEL COULD HAVE A MATERIAL ADVERSE EFFECT ON OUR BUSINESS. Our future success will depend in part on our ability to attract and retain highly-skilled employees, particularly those in management, sales, regulatory, manufacturing and technical positions. The loss of services of members of our management team could adversely affect our business and impede or delay achievement of our corporate mission. Furthermore, recruiting and retaining qualified scientific and other key employees will be critical to our success, and competition for such employees in our targeted industry and in our geographic regions is intense. In addition, many of the companies with which we compete for highly qualified personnel have greater financial and other resources than we do. We may be unable to attract and retain key employees on acceptable terms given the level and nature of such competition. S-13 ANTI-TAKEOVER PROVISIONS COULD MAKE A THIRD-PARTY ACQUISITION OF US MORE DIFFICULT. In 2002, we adopted a Shareholder Rights Plan that provided for the issuance of rights to purchase shares of Series D Junior Participating Preferred Stock of our company. Under the plan, we distributed one preferred share purchase right for each outstanding share of our common stock. Each purchase right entitles the holder to purchase from our company one one-thousandth (1/1000th) of a share of Series D Junior Participating Preferred Stock at a price of $40, subject to adjustment. The rights become exercisable, with certain exceptions, 10 business days after any party, without prior approval of our Board of Directors, acquires or announces an offer to acquire beneficial ownership of 15% or more of our common stock. In the event that any party acquires 15% or more of our common stock, we enter into a merger or other business combination, or if a substantial portion of our assets is sold after the time that the rights become exercisable, the holder of a right will receive, upon exercise of the right, shares of the common stock of the surviving or acquiring company, as applicable, having a market value of twice the exercise price of the right. The Shareholder Rights Plan may discourage or prevent certain types of transactions involving an actual or potential change in control of our company, which transactions may be beneficial to our shareholders, by causing substantial dilution to a party that attempts to acquire us on terms not approved by our Board. THIS OFFERING AND FUTURE ISSUANCES OF SHARES OF OUR COMMON STOCK OR OTHER SECURITIES WILL DILUTE SHAREHOLDERS' INTERESTS IN OUR COMPANY AND MAY ADVERSELY AFFECT THE TRADING PRICE OF OUR COMMON STOCK. The number of shares of our common stock issued and sold in this offering is substantial, and will result in dilution of existing stockholders' percentage ownership interest in our company. In addition, there can be no assurance that the funds raised by this offering or revenues from product sales will be adequate to enable us to fund our operations. We may seek additional capital through future offerings of shares of our common stock or other securities, which would cause dilution of existing stockholders' percentage interest in our company. These future offerings could also have a material and adverse effect on the trading price of our common stock.

S-15 USE OF PROCEEDS Our net proceeds, after deducting underwriting discounts and commissions and other offering expenses, from the sale of 4.5 million shares of common stock in this offering will be approximately $25.8 million. We will retain broad discretion over the use of the net proceeds from the sale of our common stock. We currently intend to use the net proceeds from this offering for general corporate purposes, including but not limited to: - the commercial launch, marketing, selling, manufacturing and other expenses related to ESTRASORB; - our internal research and development programs, such as preclinical and clinical testing and studies of our product candidates and the development of new technologies; - general working capital; and - possible future acquisitions of complementary businesses, product lines or technologies, although we are not currently engaged in negotiations with respect to any such acquisitions. We have not determined the amounts we plan to spend on any of the areas listed above or the timing of these expenditures, which may vary significantly depending on various factors such as our research and development results, regulatory approvals, competition, marketing and sales, and the market acceptance of any products introduced by us. As a result, our management will have broad discretion to allocate the net proceeds from this offering. Pending application of the net proceeds as described above, we intend to invest these net proceeds in short-term, interest-bearing, investment-grade securities.

We currently anticipate that we will retain all of our earnings for use in the development of our business and do not anticipate paying any cash dividends in the foreseeable future. S-18 UNDERWRITING We are offering the shares described in this prospectus supplement through C.E. Unterberg, Towbin, which we refer to as the "underwriter," with which we have entered an underwriting agreement. Subject to the terms and conditions of the underwriting agreement, we have agreed to sell to the underwriter, and the underwriter has agreed to purchase from us, 4,500,000 shares of our common stock. Subject to the conditions set forth in the underwriting agreement, the underwriter is obligated to purchase all of the shares of common stock offered by this prospectus supplement. The underwriter will initially offer the shares of our common stock to the public at the price specified on the cover page of this prospectus supplement. These sales may include sales to affiliates of the underwriter, including investment funds managed by the underwriter. If all the shares of our common stock offered by this prospectus supplement are not sold at the public offering price, the underwriter may change the public offering price and other selling terms. The shares are offered subject to a number of conditions, including: - receipt and acceptance of the shares by the underwriter; and - the underwriter's right to reject orders in whole and in part. Our common stock is listed on the Nasdaq National Market under the symbol "NVAX." In compliance with guidelines of the National Association of Securities Dealers, Inc., the maximum compensation to the underwriter or dealers in connection with the sale of our common stock pursuant to this prospectus supplement and the accompanying prospectus will not exceed 8% of the aggregate total offering price of the common stock as set forth on the cover page of this prospectus supplement. The maximum compensation paid to the underwriter in connection with this offering will be less than 8%. The underwriting agreement provides that we will indemnify the underwriter against civil liabilities specified in the agreement, including under the Securities Act of 1933, as amended (the "Securities Act") and for breaches of our representations and warranties contained in the underwriting agreement. If we are unable to provide indemnification, we will be required to contribute to payments that the underwriter may be required to make relating to those liabilities. COMMISSIONS AND DISCOUNTS The following table shows, on a per share and total basis, the public offering price, underwriting discounts and commissions to be paid to the underwriter and proceeds before expenses to us. PER SHARE TOTAL --------- ----- Public offering price $6.150 $27,675,000 Underwriting discounts and commissions $0.369 $ 1,660,500 Proceeds, before expenses, to Novavax $5.781 $26,014,500 We estimate that the expenses of this offering, not including the underwriting discounts and commissions, will be approximately $185,000. These expenses are payable by us. NO SALES OF SIMILAR SECURITIES We have agreed that, for a period of 30 days after the date of the underwriting agreement, we will not, without the underwriter's prior written consent, offer, sell, contract to sell, pledge, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of our common stock or any securities S-19 convertible into or exercisable or exchangeable for shares of our common stock or publicly announce an intention to effect any such transaction, except for the shares offered in this offering, shares issuable pursuant to an employee stock option plan, and shares issuable upon the exercise of outstanding options and warrants or the conversion of convertible securities that are outstanding on the date of the underwriting agreement. STABILIZATION ACTIVITIES In connection with and in order to facilitate this offering, the underwriter may engage in activities that stabilize, maintain or otherwise affect the price of the shares of our common stock, including: - stabilizing transactions; - short sales; and - purchases to cover positions created by short sales. Stabilizing transactions consist of bids or purchases made for the purpose of preventing or retarding a decline in the market price of the shares of our common stock while this offering is in progress. Stabilizing transactions may include making short sales of the shares of our common stock, which involves the sale by the underwriter of a greater number of shares of our common stock than it is required to purchase in this offering. The underwriter may close out a short position by purchasing shares of our common stock in the open market. Similar to other purchase transactions, the underwriter's purchases to cover short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of the shares of our common stock may be higher than the price that otherwise might exist in the open market. If the underwriter commences these activities, it may discontinue them at any time. The underwriter may carry out these transactions on the Nasdaq Stock Market, in the over-the-counter market or otherwise. Neither we nor the underwriter make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, neither we nor the underwriter make any representation that the underwriter will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

For a more complete understanding of this offering, you should read this entire document carefully before deciding to invest in our common stock, including the "Risk Factors" section below, and those additional documents to which we refer you. See "Where You Can Find More Information" on page 22. OUR BUSINESS Novavax is a fully-integrated specialty pharmaceutical company focused on the research, development and commercialization of products utilizing our proprietary drug delivery and vaccine technologies for large and growing markets, concentrating on the areas of women's health and infectious diseases. Our lead product candidate, ESTRASORB(TM), is the first topical emulsion for estrogen replacement therapy for which a New Drug Application has been accepted for review by the Food and Drug Administration. The NDA for ESTRASORB was submitted in June 2001 and was accepted for review in August 2001. In April 2002, we were informed by the FDA that the agency had completed its review of the NDA for ESTRASORB. At that time, the agency did not raise any issues regarding the efficacy or safety of ESTRASORB, but did request additional information with respect to the Chemistry, Manufacturing and Controls section of the filing. We determined that the most advantageous approach to resolving the outstanding CMC questions was to voluntarily withdraw the NDA and resubmit it once all of the responses to the CMC questions had been prepared. In September 2002, we re-submitted the NDA, which was accepted for review by the FDA in November 2002. In June 2003, the agency informed us that it would need additional time for a full review of our Estradiol Partner Transfer Study Report submitted in May of this year. Under the Prescription Drug User Fee Act the statutory minimum extension time is 90 days, which thus results in a new goal date for a decision on the approvability of ESTRASORB of no later than October 10, 2003. We are seeking FDA approval of ESTRASORB for the reduction of hot flushes in menopausal women and, if approved, we believe ESTRASORB will be competitively positioned to address the estimated $1.8 billion estrogen replacement therapy market in the United States. Our micellar nanoparticle technology involves the use of our patented oil and water emulsions that we believe can be used as vehicles for the topical delivery of a wide variety of drugs and other therapeutic products, including hormones. We believe that our technology represents the first time that ethanol soluble hormones, such as estrogen and testosterone, have been encapsulated and delivered topically. In addition to ESTRASORB, our product candidates using these technologies include ANDROSORB(TM), a topical testosterone emulsion that has completed two Phase I clinical trials; TESTESTRASORB(TM), a topical estrogen and testosterone emulsion; PROGESTSORB(TM) NE, a topical progestin emulsion; and PROESTRASORB(TM), a topical estrogen and progestin emulsion. Other drug delivery technologies, such as our Novasome(R) and Sterisome(R) technologies, are being utilized to develop other products. Novasomes are used as adjuvants to enhance vaccine effectiveness. Sterisomes are being used for, among other things, subcutaneous injections that can deliver long-acting drug effects. We also conduct research and development on preventative vaccines and proteins for a variety of infectious diseases and immunotherapies. Over the past three years we have entered into a co-promotion agreement with King Pharmaceuticals, Inc. for the promotion and marketing of ESTRASORB and ANDROSORB within the United States and Puerto Rico, and we have licensed to King the right to sell these products outside the United States. Our relationship with King has the potential to provide us with broader women's health market coverage for ESTRASORB and ANDROSORB. Under the terms of our co-promotion agreement with King, we will record all of the product sales, returns and allowances, and cost of sales for ESTRASORB and ANDROSORB in the United States and Puerto Rico. The resultant gross margin will be shared equally with King and the payment to King will be recorded as a selling and marketing expense on our statement of operations. In addition, following product approval by the FDA, both parties will share equally in approved marketing expenses for the products. All direct marketing expenses will be recorded by us, for which King will reimburse us fifty percent. We received licensing fees of $3.0 million and milestone payments totaling $5.0 million from King upon the submission to the FDA and acceptance for review of the ESTRASORB NDA. We have also received from King $20.0 million in December 2000, $10.0 million in September 2001 and $10.0 million in June 2002, in the form of convertible note financings. -3- We currently market, sell and distribute a line of prescription pharmaceuticals through our 64 person sales force that has extensive experience selling to obstetricians, gynecologists, managed care organizations, wholesalers and retail pharmacies throughout the United States. In 2002, these products generated revenues of $12.8 million. If we receive marketing approval from the FDA, we expect to sell ESTRASORB through both our sales force and King's sales force. We intend to manufacture ESTRASORB for commercial sale in our dedicated, state-of-the-art, 24,000 square foot facility in Philadelphia, Pennsylvania, which was substantially completed in December 2002. Our principal executive offices are located at 8320 Guilford Road, Columbia, MD 21046. Our telephone number is (301) 854-3900. We are incorporated under the laws of the State of Delaware. -4- SUMMARY CONSOLIDATED FINANCIAL DATA The historical consolidated financial data presented below as of and for each of the periods ended December 31, 2002, 2001 and 2000 were derived from our audited consolidated financial statements.

Some of the following risks relate principally to our business and the industry in which we operate. Other risks relate principally to the securities market and ownership of our common stock. If any of the following risks occur, our business, financial condition and/or operating results could be adversely affected. In that case, the trading price of our common stock could decline, and you could lose all or part of your investment. OUR SUCCESS IS HEAVILY DEPENDENT ON FDA APPROVAL AND MARKET ACCEPTANCE OF ESTRASORB. Our New Drug Application for ESTRASORB was accepted for review by the FDA in November 2002. There is no guarantee that the FDA will approve our application and allow us to begin selling ESTRASORB in the United States. If we do not receive FDA approval of our application, our inability to sell ESTRASORB in the United States would have a significant negative effect on our business and results of operations. Even if ESTRASORB is approved by the FDA, there is no guarantee that we and King Pharmaceuticals, Inc., our marketing partner for ESTRASORB, will be able to successfully commercialize ESTRASORB. Many factors could negatively affect our ability to successfully commercialize ESTRASORB, including: - a failure or delay in ESTRASORB gaining a meaningful share of the estrogen replacement therapy market, which currently is dominated by Premarin(R), an oral estrogen tablet sold by Wyeth, and estrogen patches sold by several companies including Novartis Pharma AG, Berlex Laboratories, Inc. and Forest Pharmaceuticals, Inc.; - our inability to effectively promote and sell ESTRASORB with King in the United States, or King's inability to do so in the rest of the world; - delays in the manufacture of ESTRASORB in commercial quantities; and - the inability to obtain coverage and favorable reimbursement rates for ESTRASORB from insurers and other third party payors. WE WILL FACE SUBSTANTIAL COMPETITION IN CONNECTION WITH THE SALE OF ESTRASORB AND OUR OTHER PRODUCT CANDIDATES. We compete with numerous other companies worldwide that have developed or are developing products that compete or may compete with our product candidates. These competitors include both large and small pharmaceutical companies, biotechnology firms, universities and other research institutions. We may not succeed in developing technologies and products that are more effective than those being developed by our competitors. Many large companies currently produce and sell estrogen products for clinical indications identical to those that we seek for ESTRASORB. In the oral product segment of the estrogen replacement therapy market, which accounts for approximately 74% of the market according to 2002 IMS Health Incorporated data, Wyeth commits significant resources to the sale and marketing of its product, Premarin(R), in order to maintain its market leadership position. Warner-Chillcot also competes in the branded oral product segment with its product, Estrace(R). In addition, ESTRASORB will compete with products produced and sold by generic manufacturers in the oral product segment of the market, such as Watson Pharmaceutical, Inc.'s generic product, Estropipate(R). In the patch segment of the market, which according to IMS Health accounts for approximately 15% of the estrogen replacement therapy market, several companies market transdermal estrogen patches with which ESTRASORB will compete, if approved. For example, Novartis Pharma AG currently markets and sells its Vivelle(R) and Estraderm(R) patches and Berlex Laboratories, Inc. and Forest Pharmaceuticals Inc. co-promote the Climara(R) transdermal patch. Several companies also currently market ethanol-based estrogen gels and ointments outside the United States. For example, Schering Canada sells its estrogen gel, Estrogel(R), in Canada. These and other products sold by our competitors have all been approved for sale and have achieved some degree of market penetration. If ESTRASORB is approved for sale in the Untied States, it will compete for market share with these products and we cannot guarantee that, together with King, we will be able to effectively promote ESTRASORB against these competitive products. In order to -6- effectively compete, we may make substantial investments in sales and marketing. Many of these products are sold by companies with greater resources than we have and there is no assurance that we will be successful in gaining significant market share for ESTRASORB or in earning a return on that investment. Our technologies and products may be rendered obsolete or noncompetitive as a result of products introduced by competitors. Most of our competitors have substantially greater financial and technical resources, production and marketing capabilities, and related experience than we do. The greater resources, capabilities and experience of our competitors may enable them to develop, manufacture and market their products more successfully and at a lower cost than we can. In addition, many of our competitors have significantly greater experience than we do in conducting preclinical testing and clinical trials of human pharmaceuticals and obtaining regulatory approvals to market such products. Accordingly, our competitors may succeed in obtaining FDA approval for products more rapidly than we will, which may give them an advantage over us in achieving market acceptance of their products. WE WOULD NEED ADDITIONAL CAPITAL TO GROW AND OPERATE OUR BUSINESS IN THE EVENT WE WERE UNABLE TO RAISE CAPITAL IN THIS OFFERING, AND WE ARE UNCERTAIN ABOUT OBTAINING FUTURE FINANCING. We estimate that our existing cash resources will be sufficient to finance our operations at current and projected levels of development and general corporate activity for the next 5 to 7 months. We cannot be certain that we will be able to generate revenues from product sales in the near term or at all sufficient to fund our operations. If w were unable to raise capital in this offering, we would require additional funds to continue our research and development, commence future preclinical and clinical trials, seek regulatory approvals, establish commercial-scale manufacturing capabilities, and market our products. We may seek additional funds through public or private equity or debt financings, collaborative arrangements with pharmaceutical companies and other sources. We cannot be certain that adequate additional funding will be available to us on acceptable terms, if at all. If we cannot raise the additional funds we may need to continue our current and anticipated operations, we may be required to delay significantly, reduce the scope of, or eliminate one or more of, our research or development programs. If that is the case, we will seek other alternatives to avoid insolvency, including arrangements with collaborative partners or others that may require us to relinquish rights to certain of our technologies, product candidates or products. WE HAVE A HISTORY OF LOSSES AND OUR FUTURE PROFITABILITY IS UNCERTAIN. Our expenses have exceeded our revenues since our formation in 1987, and our accumulated deficit at June 30, 2003 was $98.4 million. Our revenues for the last three years were $15.0 million in 2002, $24.0 million in 2001 and $2.5 million in 2000. For the six months ended June 30, 2003 and 2002, our revenues were $3.5 million and $10.2 million, respectively. Sales of products that we acquired as a result of our acquisition of Fielding Pharmaceutical Company in 2000 have generated modest revenues, but based on our current business plan these revenues will not be sufficient to offset our expenses in the future. We cannot be certain when or if we will generate substantial revenues from the sale of ESTRASORB. We have received a very limited amount of product-related revenue from research contracts, licenses and agreements to provide vaccine products, services and adjuvant technologies. We cannot be certain that we will be successful in entering into strategic alliances or collaborative arrangements with other companies that will result in other significant revenues to offset our expenses. Our net losses for the last three years were $22.7 million in 2002, $9.7 million in 2001 and $12.1 million in 2000, while they were $10.8 million and $11.5 million for the six months ended June 30, 2003 and 2002, respectively. Our losses have resulted from research and development expenses, pre-launch sales and marketing expenses in the anticipation of FDA approval for ESTRASORB, protection of our intellectual property, and other general operating expenses. Our annual losses may increase depending on the timing of the FDA approval and launch of ESTRASORB as we expand our manufacturing capacity, sales and marketing capabilities and conduct additional and larger clinical trials for other product candidates. Therefore, we expect our cumulative operating loss to increase until such time, if ever, as product sales, licensing fees and royalty payments generate sufficient revenue to fund our continuing operations. We cannot predict when, if ever, we might achieve profitability and cannot be certain that we will be able to sustain profitability, if achieved. We intend to allocate a significant portion of our sales force's time to the product launch of ESTRASORB, if and when it is approved by the FDA. Accordingly, the sales of our other women's health products could be adversely affected by the efforts we allocate to the ESTRASORB product launch. The costs of maintaining our own -7- sales force to market our current products and ESTRASORB, if approved, may in the future exceed product revenues. If we continue to market ESTRASORB or future products directly, significant additional expenditures and management resources may be required to increase the size of our internal sales force. OUR SALES AND MARKETING PLAN FOR ESTRASORB DEPENDS IN LARGE PART ON THE SUCCESS OF OUR RELATIONSHIP WITH KING. We have entered into a co-promotion agreement with King for the marketing and promotion of ESTRASORB in the United States using our sales and marketing personnel and King's sales and marketing personnel. We have also granted King exclusive rights to promote, market and distribute ESTRASORB outside the United States. In return, we received certain milestone payments and the agreement to pay potential future milestone payments and licensing fees and royalties on future sales. While our agreements with King give us some limited protections with respect to King's marketing and sales efforts and, we believe, create financial incentives for King consistent with our own, we cannot control the amount and timing of marketing efforts that King devotes to ESTRASORB or make any assurances that our and King's co-promotion of ESTRASORB in the United States and King's marketing of ESTRASORB in the rest of the world will be successful. Our success in marketing other potential future products will also depend in large part on our relationship with King. Our co-promotion agreement with King also provides for co-promotion in the United States with King of our product candidate ANDROSORB(TM). If this product is approved for marketing by the FDA, King has an exclusive worldwide license, except in the United States, to market this future product. Under our co-promotion agreement, King has the right to co-promote certain future hormone replacement therapy products in the field of women's health. In the future, we might enter into other licensing or co-promotion arrangements with King or other third parties for the marketing and sale of other future products. Any revenues we receive from sales of ANDROSORB and other future products will depend in large part on the terms of these agreements and the efforts of King and any other third-party marketing partners. OUR AGREEMENTS WITH KING REDUCE THE LIKELIHOOD THAT WE COULD BE ACQUIRED BY ANOTHER COMPANY. Our co-promotion agreement and license agreement with King for the marketing of ESTRASORB and ANDROSORB contain several provisions that would take effect upon a change of control of the Company. One provision allows King several options in the event of a change in control of Novavax including (i) terminating our right to co-promote King products, (ii) terminating our rights to promote ESTRASORB and ANDROSORB and certain other hormone therapies for women, or (iii) requiring Novavax to assign and transfer to King all related rights of ownership for ESTRASORB and ANDROSORB and certain other hormone replacement therapies for women and license to King on an exclusive and perpetual basis all intellectual property rights and know-how. If King chooses to exercise its rights under either clause (ii) or (iii) above, King will pay us royalties on net sales of the products. In addition, King will pay us for the cost of manufacturing, plus a markup consistent with the terms of the license agreement for the handling costs. King could also require that we redeem the outstanding promissory notes, currently in the amount of $40.0 million, at 101% of the outstanding principal and accrued interest. These provisions may have the effect of making us less attractive as an acquisition candidate. WE NEED ADDITIONAL MANUFACTURING CAPABILITY TO COMMERCIALIZE OUR PRODUCTS. We do not have any experience with the large capacity manufacturing required for commercial sale of a product. Although we have had the ability to produce the limited quantities of products needed to support our current research and development program and clinical trials (including utilizing contract manufacturing organizations), we will need more production capacity for larger, later-stage clinical studies and commercial sales. Our potential products may be too difficult or costly to manufacture on a large scale, to develop into commercially viable products or to market. We have validated our manufacturing methods for ESTRASORB, which has been produced in 100-kilo size batches. Such validation is required under FDA guidelines, and we have received preliminary FDA approval of these methods. We currently manufacture ESTRASORB at a facility of Cardinal Health, Inc. in Philadelphia, Pennsylvania. In February 2002, we entered into an agreement with Cardinal Health to lease approximately 24,000 square feet of space within their facility. Under the terms of this agreement, Cardinal Health will also provide -8- packaging services for the product we manufacture in their facility. We have substantially completed the build out of the facility to meet our requirements and have installed manufacturing equipment at this facility with the capacity required for commercial production of ESTRASORB. Now that this new equipment is installed, we need to validate that the ESTRASORB made using this new equipment is identical to that used in our clinical trials. If we are unable to make ESTRASORB on a commercial scale or are delayed in validating the product manufactured with our new equipment, the commercialization of ESTRASORB would be delayed. In the near term, we will be manufacturing ESTRASORB only in the Philadelphia facility. If ESTRASORB is approved by the FDA, we plan to qualify at least one additional site for the manufacture of ESTRASORB. If we are unable to utilize the Philadelphia facility to manufacture ESTRASORB prior to our qualification of a second site, however, we would not have immediate access to ESTRASORB and would be required to reestablish our validation process at a different facility that would cause us to lose sales of ESTRASORB and would adversely affect our business. We currently utilize third party contract manufacturers to manufacture our other products. Any contract manufacturer's facility that we may use, including the Cardinal Health facility, must adhere to the FDA's regulations on current good manufacturing practices, which are enforced by the FDA through its facilities inspection program. These facilities are subject to periodic inspection by the FDA. The manufacture of products at these facilities will be subject to strict quality control testing and record-keeping requirements. We may not be able to enter into alternative manufacturing arrangements at commercially acceptable rates, if at all. Moreover, the manufacturers we use may not provide sufficient quantities of product to meet our specifications or our delivery, cost and other requirements. If we decide to manufacture our own products, we will need to acquire additional manufacturing facilities and to improve our manufacturing technology. Establishing additional manufacturing facilities will require us to spend substantial funds, hire and retain a significant number of additional personnel and comply with extensive regulations applicable to such facilities here and abroad, including the current good laboratory practices and good manufacturing practices required by the FDA. If we elect to or need to manufacture our own products, we risk the possibility that we may not be able to do so in a timely fashion at acceptable quality and prices or in compliance with good laboratory practices and good manufacturing practices. WE HAVE NOT COMPLETED THE DEVELOPMENT OF MANY OF OUR PRODUCTS AND WE MAY NOT SUCCEED IN OBTAINING THE FDA APPROVAL NECESSARY TO SELL ANY ADDITIONAL PRODUCTS. The development, manufacture and marketing of our pharmaceutical products are subject to government regulation in the United States and other countries. In the United States and most foreign countries, we must complete rigorous preclinical testing and extensive human clinical trials that demonstrate the safety and efficacy of a product in order to apply for regulatory approval to market the product. Only a few of our products have been approved for sale and our application to sell ESTRASORB in the United States is currently being reviewed by the FDA. Our product candidate, ANDROSORB, has completed two Phase I human clinical studies. Our other product candidates are in preclinical laboratory or animal studies. Before applying for FDA approval to market any additional product candidates, we must conduct larger-scale Phase II and III human clinical trials that demonstrate the safety and efficacy of our products to the satisfaction of the FDA or other regulatory authorities. These processes are expensive and can take many years to complete. We may not be able to demonstrate the safety and efficacy of our products to the satisfaction of the FDA or other regulatory authorities. We may also be required to demonstrate that our proposed products represent an improved form of treatment over existing therapies and we may be unable to do so without conducting further clinical studies. We may fail to obtain regulatory approval for our products on a timely basis. Delays in obtaining regulatory approval can be extremely costly in terms of lost sales opportunities and increased clinical trial costs. The speed with which we complete our clinical trials and our applications for marketing approval will depend on several factors, including the following: - the rate of patient enrollment, which is a function of many factors, including the size of the patient population, the proximity of patients to clinical sites, the eligibility criteria for the study and the nature of the protocol; -9- - institutional review board approval of the protocol and the informed consent form; - prior regulatory agency review and approval; - analysis of data obtained from preclinical and clinical activities that are susceptible to varying interpretations, which interpretations could delay, limit or prevent regulatory approval; - changes in the policies of regulatory authorities for drug approval during the period of product development; and - the availability of skilled and experienced staff to conduct and monitor clinical studies and to prepare the appropriate regulatory applications. We have limited experience in conducting and managing the preclinical and clinical trials necessary to obtain regulatory marketing approvals. We may not be able to obtain the approvals necessary to conduct clinical studies. Also, the results of our clinical trials may not be consistent with the results obtained in preclinical studies or the results obtained in later phases of clinical trials may not be consistent with those obtained in earlier phases. A number of companies in the specialty pharmaceutical industry have suffered significant setbacks in advanced clinical trials, even after experiencing promising results in early animal and human testing. If regulatory approval of a drug is granted, such approval is likely to limit the indicated uses for which it may be marketed. Furthermore, even if a product of ours gains regulatory approval, the product and the manufacturer of the product will be subject to continuing regulatory review. We may be restricted or prohibited from marketing or manufacturing a product, even after obtaining product approval, if previously unknown problems with the product or its manufacture are subsequently discovered. OUR SUCCESS DEPENDS ON OUR ABILITY TO MAINTAIN THE PROPRIETARY NATURE OF OUR TECHNOLOGY. Our success will, in large part, depend on our ability to maintain the proprietary nature of our technology and other trade secrets. To do so, we must prosecute and maintain existing patents, obtain new patents and pursue trade secret protection. We also must operate without infringing the proprietary rights of third parties or letting third parties infringe our rights. We currently have 55 U.S. patents and approximately 150 foreign patents and patent applications covering our technologies. We recently filed eight new patent applications in the US and worldwide directed towards innovative discoveries made in the field of human Papillomavirus virus-like particles. However, patent issues relating to pharmaceuticals involve complex legal, scientific and factual questions. To date, no consistent policy has emerged regarding the breadth of biotechnology patent claims that are granted by the United States Patent and Trademark Office or enforced by the federal courts. Therefore, we do not know whether our applications will result in the issuance of patents, or that any patents issued to us will provide us with any competitive advantage. We also cannot be sure that we will develop additional proprietary products that are patentable. Furthermore, there is a risk that others will independently develop or duplicate similar technology or products or circumvent the patents issued to us. There is a risk that third parties may challenge our existing patents or may claim that we are infringing their patents or proprietary rights. We could incur substantial costs in defending patent infringement suits or in filing suits against others to have their patents declared invalid or claim infringement. It is also possible that we may be required to obtain licenses from third parties to avoid infringing third-party patents or other proprietary rights. We cannot be sure that such third-party licenses would be available to us on acceptable terms, if at all. If we are unable to obtain required third-party licenses, we may be delayed in or prohibited from developing, manufacturing or selling products requiring such licenses. Although our patents include claims covering various features of our product candidates, including composition, methods of manufacture and use, our patents do not provide us with complete protection against the development of competing products. For example, our patents do not prohibit third parties from developing and selling products for estrogen replacement therapy that deliver estrogen through a topical emulsion, ointment or similar medium. -10- Some of our know-how and technology is not patentable. To protect our proprietary rights in unpatentable intellectual property and trade secrets, we require employees, consultants, advisors and collaborators to enter into confidentiality agreements. These agreements may not provide meaningful protection for our trade secrets, know-how or other proprietary information in the event of any unauthorized use or disclosure. HEALTH CARE INSURERS AND OTHER PAYORS MAY NOT PAY FOR OUR PRODUCTS OR MAY IMPOSE LIMITS ON REIMBURSEMENT. Our ability to commercialize ESTRASORB and our future products will depend, in part, on the extent to which reimbursement for such products will be available from third-party payors, such as Medicare, Medicaid, health maintenance organizations, health insurers and other public and private payors. If we succeed in bringing ESTRASORB or other products in the future to market, we cannot be assured that third-party payors will pay for ESTRASORB or will establish and maintain price levels sufficient for realization of an appropriate return on our investment in product development. For example, ESTRASORB, if approved for commercial sale in the United States, would be sold as an outpatient prescription drug. Medicare does not cover the costs of most outpatient prescription drugs. We expect that ESTRASORB will be treated the same as other estrogen replacement therapy products with respect to government and third-party payor reimbursement. However, we cannot be assured that ESTRASORB will receive similar reimbursement treatment. Many health maintenance organizations and other third-party payors use formularies, or lists of drugs for which coverage is provided under a health care benefit plan, to control the costs of prescription drugs. Each payor that maintains a drug formulary makes its own determination as to whether a new drug will be added to the formulary and whether particular drugs in a therapeutic class will have preferred status over other drugs in the same class. This determination often involves an assessment of the clinical appropriateness of the drug and sometimes the cost of the drug in comparison to alternative products. We cannot be assured that ESTRASORB or any of our future products will be added to payors' formularies, that our products will have preferred status to alternative therapies, or that the formulary decisions will be conducted in a timely manner. We may also decide to enter into discount or formulary fee arrangements with payors, which could result in us receiving lower or discounted prices for ESTRASORB or future products. WE MAY HAVE PRODUCT LIABILITY EXPOSURE. The administration of drugs to humans, whether in clinical trials or after marketing clearances are obtained, can result in product liability claims. We maintain product liability insurance coverage in the total amount of $18.0 million for claims arising from the use of our currently marketed products and products in clinical trials prior to FDA approval. Coverage is becoming increasingly expensive, however, and we may not be able to maintain insurance at a reasonable cost. We cannot be assured that we will be able to maintain our existing insurance coverage or obtain coverage for the use of our other products in the future. This insurance coverage and our resources may not be sufficient to satisfy liabilities resulting from product liability claims. A successful claim may prevent us from obtaining adequate product liability insurance in the future on commercially desirable terms, if at all. Even if a claim is not successful, defending such a claim may be time-consuming and expensive and may damage our reputation in the marketplace. WE HAVE MADE LOANS TO CERTAIN OF OUR DIRECTORS, AND HAVE GUARANTEED A BROKERAGE MARGIN LOAN FOR ONE OF THESE DIRECTORS THAT COULD HAVE A NEGATIVE IMPACT ON OUR STOCK PRICE. In 2002, pursuant to our Stock Option Plan, we approved the payment of the exercise price of options by two directors through the delivery of full recourse interest bearing promissory notes, in the aggregate amount of approximately $1.5 million, secured by a pledge of the underlying shares. In addition, in 2002 we executed a conditional guaranty of a brokerage margin account for a director in the amount of $500,000. Due to heightened sensitivity in the current environment surrounding related party transactions, these transactions could be viewed negatively in the market and our stock price could be negatively affected. -11- THE PRICE OF OUR COMMON STOCK HAS BEEN, AND MAY CONTINUE TO BE, VOLATILE. Historically, the market price of our common stock has fluctuated over a wide range. In fiscal 2002, our common stock traded in a range from a low of $1.59 to a high of $14.00. In fiscal 2003, our common stock has traded in a range from a low of $2.52 to a high of $6.87 as of August 8, 2003. It is likely that the price of our common stock will fluctuate in the future. The market prices of securities of small capitalization specialty pharmaceutical companies, including ours, from time to time experience significant price and volume fluctuations unrelated to the operating performance of particular companies. In particular, over the next year, the market price of our common stock may fluctuate significantly due to a variety of factors, including: - governmental agency actions, including the FDA's determination with respect to our pending NDA for ESTRASORB; - our ability to obtain financing; and - sales of our products, particularly ESTRASORB, if it is approved for sale. In addition, the occurrence of any of the risks described in this "Risk Factors" section could have a dramatic and adverse impact on the market price of our common stock. OUR SUBSTANTIAL DEBT COULD ADVERSELY AFFECT OUR CASH FLOW AND PREVENT US FROM FULFILLING OUR OBLIGATIONS. We currently have $41.6 million of outstanding debt. Our substantial amount of debt could have important consequences to you. For example, it: - could increase our vulnerability to general adverse economic and industry conditions; - will require us to dedicate a substantial portion of our cash flow from operations to service payments on our debt, reducing the availability of our cash flow to fund future capital expenditures, working capital, execution of our growth strategy, research and development costs and other general corporate requirements; - could limit our flexibility in planning for, or reacting to, changes in our business and the pharmaceutical industry, which may place us at a competitive disadvantage compared with competitors that have less debt; and - could limit our ability to borrow additional funds, even when necessary to maintain adequate liquidity. We may incur additional debt for various reasons, which, if over a certain amount, must be approved by King. Any such additional debt could be senior to the common stock being offered in this offering and would increase the risks associated with our substantial leverage. OUR INABILITY TO RECRUIT AND RETAIN MEMBERS OF OUR MANAGEMENT TEAM AND KEY PERSONNEL COULD HAVE A MATERIAL ADVERSE EFFECT ON OUR BUSINESS. Our future success will depend in part on our ability to attract and retain highly skilled employees, particularly those in management, sales, regulatory, manufacturing and technical positions. The loss of services of members of our management team could adversely affect our business and impede or delay achievement of our corporate mission. Furthermore, recruiting and retaining qualified scientific and other key employees will be critical to our success, and competition for such employees in our targeted industry and in our geographic regions is intense. In addition, many of the companies with which we compete for highly qualified personnel have greater financial and other resources than we do. We may be unable to attract and retain key employees on acceptable terms given the level and nature of such competition. -12- ANTI-TAKEOVER PROVISIONS COULD MAKE A THIRD-PARTY ACQUISITION OF US MORE DIFFICULT. In 2002, we adopted a Shareholder Rights Plan that provided for the issuance of rights to purchase shares of Series D Junior Participating Preferred Stock of the Company. Under the plan, we distributed one preferred share purchase right for each outstanding share of common stock. Each purchase right entitles the holder to purchase from the Company one one-thousandth (1/1000th) of a preferred share at a price of $40 per one one-thousandth (1/1,000th) of a share, subject to adjustment. The rights become exercisable, with certain exceptions, ten business days after any party, without prior approval of our Board of Directors, acquires or announces an offer to acquire beneficial ownership of 15% or more of the Company's common stock. In the event that any party acquires 15% or more of the Company's common stock, the Company enters into a merger or other business combination, or if a substantial portion of the Company's assets is sold after the time that the rights become exercisable, the rights provide that the holder will receive, upon exercise, shares of the common stock of the surviving or acquiring company, as applicable, having a market value of twice the exercise price of the right. The Shareholder Rights Plan may discourage or prevent certain types of transactions involving an actual or potential change in control, which transactions may be beneficial to our shareholders, by causing substantial dilution to a party that attempts to acquire us on terms not approved by our Board. -13- ABOUT THIS PROSPECTUS This prospectus is part of a "shelf" registration statement that we filed with the Securities and Exchange Commission (the "SEC"). By using a shelf registration statement, we may, from time to time, sell shares of our common stock in one or more offerings with a maximum aggregate offering price of $50,000,000. Each time we sell any of our common stock, we will provide a prospectus supplement that will contain specific information about the offering. This prospectus and the prospectus supplements provide you with a general description of the company and our common stock; for further information about our business and our securities, you should refer to the registration statement, the reports incorporated by reference in this prospectus, and its exhibits. The exhibits to our registration statement contain the full text of certain contracts and other important documents we have summarized in this prospectus. Since these summaries may not contain all the information that you may find important in deciding whether to purchase the securities we may offer, you should review the full text of these documents. The registration statement can be obtained from the SEC as indicated under the heading "Where You Can Find More Information." You should rely only on the information contained or incorporated by reference in this prospectus and the prospectus supplement. We have not authorized anyone to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. We will not make an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing in this prospectus, as well as information we previously filed with the SEC and incorporated by reference in this prospectus, is accurate only as of the date on the front cover of this prospectus. Our business, financial condition, results of operations and prospects may have changed since that date. -14- SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS We caution you that this prospectus contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements are based on management's beliefs and assumptions and on information currently available to management, and use words such as "expect," "anticipate," "intend," "plan," "believe," "estimate," "may," "could," "possible," "forecast," or similar words and expressions. Forward-looking statements include information concerning possible or assumed future results of operations, future product development and related clinical trials and statements regarding future research and development. Forward-looking statements are only predictions, and necessarily involve risks and uncertainties and other factors that may cause the actual results, performance or achievements of Novavax, or industry results, to be materially different from those anticipated in the forward-looking statements. These risks and uncertainties are discussed in the "Risk Factors" section and elsewhere in this prospectus. -15- USE OF PROCEEDS Except as otherwise described in an applicable prospectus supplement, we currently intend to use the net proceeds from this offering for general corporate purposes, including but not limited to: - our internal research and development programs, such as preclinical and clinical testing and studies of our product candidates and the development of new technologies, - pre-launch, marketing, and other expenses related to product candidate ESTRASORB, if approved by the FDA, - general working capital, and - possible future acquisitions of complementary businesses, product lines or technologies, although no such transactions are currently under negotiation. We have not determined the amounts we plan to spend on any of the areas listed above or the timing of these expenditures, which may vary significantly depending on various factors such as our research and development results, regulatory approvals, competition, marketing and sales, and the market acceptance of any products introduced by us. As a result, our management will have broad discretion to allocate the net proceeds from this offering. Pending application of the net proceeds as described above, we intend to invest the net proceeds of this offering in short-term, interest-bearing, investment-grade securities. -16- PLAN OF DISTRIBUTION We may sell the securities being offered hereby from time to time in one or more of the following ways: - through one or more underwriters, - through dealers, who may act as agents or principal (including a block trade in which a broker or dealer so engaged will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction), - directly to one or more purchasers, - through agents, - in privately negotiated transactions, and - in any combination of these methods of sale. We will set forth in a prospectus supplement the terms of the offering of securities, including: - the name or names of any agents, underwriters or dealers, - the purchase price of the common stock being offered and the proceeds we will receive from the sale, - any underwriting discounts and commissions or agency fees and other items constituting underwriters' or agents' compensation, - any over-allotment options under which underwriters may purchase additional securities from us, and - any discounts or concessions allowed or reallowed or paid to dealers. The distribution of the common stock may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, at market prices prevailing at the time of sale, at prices related to the prevailing market prices, or at negotiated prices. Underwriters, dealers and agents that participate in the distribution of the common stock may be underwriters as defined in the Securities Act of 1933, as amended (the "Securities Act") and any discounts or commissions they receive from us and any profit on their resale of the common stock may be treated as underwriting discounts and commissions under the Securities Act. We will identify in the applicable prospectus supplement any underwriters, dealers or agents and will describe their compensation. We may have agreements with underwriters, dealers and agents to indemnify them against specified civil liabilities, including liabilities under the Securities Act. Underwriters, dealers and agents may engage in transactions with or perform services for us in the ordinary course of their businesses. We have not entered into any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of their securities. As of the date of this prospectus, there are no special selling arrangements between any broker-dealer or other person and the Company. No period of time has been fixed within which the shares will be offered or sold. If required under applicable state securities laws, we will sell the common stock only through registered or licensed brokers or dealers. In addition, in some states, we may not sell shares of common stock unless they have been registered or qualified for sale in the applicable state or unless we have complied with an exemption from any registration or qualification requirements. -17- AGENTS We may designate agents who agree to solicit purchases for the period of their appointment or to sell common stock on a continuing basis. Unless the prospectus supplement provides otherwise, agents will act on a best efforts basis for the period of their appointment. Agents may receive compensation in the form of commissions, discounts or concessions from us. Agents may also receive compensation from the purchasers of the common stock for whom they sell as principals. Each particular agent will receive compensation in amounts negotiated in connection with the sale, which might be in excess of customary commissions. UNDERWRITERS If we use underwriters for a sale of common stock, the underwriters will acquire the common stock for their own account. The underwriters may resell the common stock in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the common stock will be subject to the conditions set forth in the applicable underwriting agreement. Unless the prospectus supplement provides otherwise, underwriters will be obligated to purchase all of the shares of common stock offered by the prospectus supplement. We may change from time to time any initial public offering price and any discounts or concessions the underwriters allow or reallow or pay to dealers. We may use underwriters with whom we have a material relationship, and we may offer the securities to the public through an underwriting syndicate or through a single underwriter. We will describe in the prospectus supplement naming the underwriter the nature of any such relationship and underwriting arrangement. DEALERS We also may sell securities to a dealer as principal. If we sell our common stock to a dealer as a principal, then the dealer may resell those shares to the public at varying prices to be determined by such dealer at the time of resale. The name of the dealer and the terms of the transactions will be set forth in the applicable prospectus supplement. DIRECT SALES AND INSTITUTIONAL PURCHASES We may also sell common stock directly to one or more purchasers, in which case underwriters or agents would not be involved in the transaction. Further, we may authorize agents, underwriters or dealers to solicit offers by certain types of institutional investors to purchase common stock from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. We will describe the conditions to these contracts and the commissions we must pay for solicitation of these contracts in the prospectus supplement. STABILIZATION ACTIVITIES Any underwriter may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in accordance with Regulation M under the Exchange Act of 1934, as amended (the "Exchange Act"). Overallotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve purchases of the common stock in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the common stock originally sold by the dealer are purchased in a covering transaction to cover short positions. Those activities may cause the price of the common stock to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time. These transactions may be effected on the Nasdaq Stock Market or otherwise. -18- PASSIVE MARKET MAKING Any underwriters who are qualified market markers on the Nasdaq National Market may engage in passive market making transactions in the common stock on the Nasdaq National Market in accordance with Rule 103 of Regulation M, during the business day prior to the pricing of the offering, before the commencement of offers or sales of the common stock. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker's bid, however, the passive market maker's bid must then be lowered when certain purchase limits are exceeded. COSTS We will bear all costs, expenses and fees in connection with the registration of the common stock, as well as the expense of all commissions and discounts, if any, attributable to the sales of the common stock by us. -19- DESCRIPTION OF OUR CAPITAL STOCK Our authorized capital stock consists of: (i) 50,000,000 shares of common stock, par value $.01 per share, of which 30,142,300 shares were outstanding as of August 8, 2003, and (ii) 2,000,000 shares of preferred stock, par value $.01 per share, none of which are outstanding. Our common stock is traded on the Nasdaq National Market under the symbol NVAX. On August 8, 2003, the closing price of our common stock as reported on the Nasdaq National Market was $5.66 per share. COMMON STOCK Holders of common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders and do not have cumulative voting rights. Accordingly, holders of a majority of the shares of our common stock entitled to vote in any election of directors may elect all of the directors standing for election. Holders of our common stock are entitled to receive ratably such dividends, if any, as may be declared by the Board of Directors out of funds legally available therefor, subject to any preferential dividend rights of any outstanding preferred stock. Upon the liquidation, dissolution or winding up of our Company, the holders of our common stock are entitled to receive ratably the net assets of our Company available after the payment of all debts and liabilities and subject to the prior rights of any outstanding preferred stock. Shares of our common stock are, and the shares being distributed in this offering will be, when issued, fully paid and nonassessable. The rights, preferences and privileges of holders of our common stock are subject, and may be adversely affected by, the rights of holders of shares of any series of preferred stock which we may designate and issue in the future. PREFERRED STOCK The Board of Directors may, without further action by the stockholders of our Company, issue preferred stock in one or more series and fix the rights and preferences thereof, including the dividend rights, dividend rates, conversion rights, voting rights, pre-emptive rights, terms of redemption (including sinking fund provisions), redemption prices and liquidation preferences. Our Amended and Restated Certificate of Incorporation grants the Board of Directors authority to issue preferred stock and to determine its rights and preferences without the need for further stockholder approval to eliminate delays associated with a stockholder vote on specific issuances. The issue of preferred stock, while providing desirable flexibility in connection with possible financings, could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from acquiring, a majority of the outstanding voting stock of our Company. We have no present plans to issue any shares of preferred stock. OPTIONS AND WARRANTS The Novavax 1995 Stock Option Plan (the "Plan") was adopted by the Board of Directors and approved by the stockholders in September, 1995 and will terminate in 2005. The Plan was amended by resolution of the Board of Directors adopted in March 1998 and approved by the stockholders in May 1998 to increase the number of shares as to which options may be granted from 4,000,000 to 4,400,000. The Plan was again amended by resolution of the Board of Directors adopted in March 2000 and approved by the stockholders in May 2000 to increase the number of shares as to which options may be granted from 4,400,000 to 6,000,000. The Plan was again amended by resolution of the Board of Directors adopted in March 2002 and approved by the stockholders in May 2002 to increase the number of shares as to which options may be granted from 6,000,000 to 8,000,000. Most recently, the Plan was amended by resolution of the Board of Directors adopted in March 2003 and approved by the stockholders in May 2003 to increase the number of shares as to which options may be granted from 8,000,000 to 9,000,000. Options granted under the Plan may be either incentive stock options within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended, or options that do not meet the requirements for incentive stock option treatment, to officers, directors, employees and consultants or advisors to our Company and any present or future subsidiary to purchase a maximum of 9,000,000 shares of our common stock. As of August 8, 2003, under both this plan and a prior stock option plan for directors, there were outstanding options to purchase 4,684,908 shares of our common stock at an average exercise price of $5.46 per share. There were 1,819,009 shares available for future grant as of August 8, 2003. -20- In addition, we have granted warrants to consultants. At August 8, 2003, there were outstanding warrants to purchase 70,000 shares of our common stock at an exercise price of $6.00 per share. CONVERTIBLE NOTES We have issued four convertible notes to King Pharmaceuticals, Inc. that are currently convertible into an aggregate of 5,075,241 shares of our common stock. The conversion price of each of the notes represents an 18% premium to the 20 day trading average preceding the agreed-upon lock-in dates prior to the issuance of each of the notes. The notes carry a 4% coupon payable semi-annually in cash and stock. The notes allow the Company the option, under certain circumstances, to pay up to 50% of the interest due in our common stock. We can require King to convert the notes into our common stock at any time from January 1, 2002 through December 31, 2004 if the closing price of our common stock exceeds 180% of the conversion price then in effect for at least 30 trading days in any period of 45 consecutive trading days. After December 31, 2004, we can redeem the notes at 102%, 101% and 100% of face value during the years ended December 31, 2005, 2006 and 2007, respectively. SHAREHOLDER RIGHTS PLAN We have adopted a Shareholder Rights Plan pursuant to which the Board of Directors declared a dividend distribution of one preferred stock purchase right for each outstanding share of common stock. Each right, once exercisable, entitles the holder to purchase from us one one-thousandth (1/1,000th) of a share of Series D Junior Participating Preferred Stock (the "Preferred Stock"), at a price of $40.00, subject to certain adjustments. The rights, unless earlier redeemed by the Board, become exercisable upon the close of business on the day which is the earlier of (i) the tenth business day following a public announcement that a person or group of affiliated or associated persons (with certain exceptions) has acquired beneficial ownership of 15% or more of the outstanding voting stock of the Company, and (ii) the tenth business day after the date of the commencement by any person of a tender or exchange offer, the consummation of which would result in such person or group of affiliated or associated persons becoming an "acquiring person" as defined in the rights plan. The rights expire at the close of business on August 7, 2012, unless earlier redeemed or exchanged by us as described below. Unless the rights are earlier redeemed, in the event that a person or group becomes an "acquiring person," the rights plan provides that proper provisions will be made so that each holder of record of a right (other than rights beneficially owned by an acquiring person and certain of its affiliates, associates and transferees) will thereafter have the right to receive, upon payment of the exercise price, that number of shares of the Preferred Stock having a fair market value determined in accordance with the rights plan at the time of the transaction equal to approximately two times the exercise price (such value to be determined with reference to the fair market value of our common stock as provided in the rights plan). In addition, unless the rights are earlier redeemed or exchanged, in the event that, after the time that a person or group becomes an acquiring person, we were to be acquired in a merger or other business combination (in which any shares of common stock are changed into or exchanged for other securities or assets) or more than 50% of the assets or earning power of the Company and its subsidiaries (taken as a whole) were to be sold or transferred in one or a series of related transactions, the rights plan provides that proper provision will be made so that each holder of record of a right (other than rights beneficially owned by an acquiring person and certain of its affiliates, associates and transferees) will have the right to receive, upon payment of the exercise price, that number of shares of common stock of the acquiring company having a fair market value at the time of such transaction determined in accordance with the rights plan equal to approximately two times the exercise price. At any time after any person or group becomes an acquiring person and prior to the acquisition by such person or group of 50% or more of the outstanding voting stock, the Board may exchange the rights, in whole or in part, for that number of shares of the Preferred Stock having a fair market value on the date such person or group became an acquiring person equal to the excess of (i) the fair market value of Preferred Stock issuable upon the exercise of the rights over (ii) the exercise price of the rights, in each case subject to anti-dilution adjustments. -21- At any time prior to the close of business on the tenth business day after there has been a public announcement that a person has become an acquiring person or such earlier date as a majority of the Board shall become aware of the existence of an acquiring person, we may redeem the rights in whole, but not in part, at a price of $.001 per right. Immediately upon the effective time of such Board action, the right to exercise the rights will terminate and the only right of the holders will be to receive the redemption price. For as long as the rights are then redeemable, we may, except with respect to the redemption price, amend the rights in any manner, including extending the time period in which the rights may be redeemed. At any time when the rights are not then redeemable, we may amend the rights in any manner that does not materially adversely affect the interests of holders of the rights as such.
