                               PROSPECTUS SUMMARY

        This summary highlights selected information contained elsewhere or
incorporated by reference in this prospectus, and may not contain all of the
information that is important to you. 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

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.

                                  RISK FACTORS

        You should carefully read the following risk factors in addition to the
remainder of this prospectus before purchasing any shares of our common stock.
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.

               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.

                                 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.

                              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.

Item 15. Indemnification of Directors and Officers.

        Section 145 of the Delaware General Corporation Law provides that a
corporation has the power to indemnify a director, officer, employee or agent of
the corporation and certain other persons serving at the request of the
corporation in related capacities against amounts paid and expenses incurred in
connection with an action or proceeding to which he or she is or is threatened
to be made a party by reason of such position, if such person shall have acted
in good faith and in a manner he or she reasonably believed to be in or not
opposed to the best interests of the corporation, and, in any criminal
proceeding, if such person had no reasonable cause to believe his or her conduct
was unlawful, provided that, in the case of actions brought by or in the right
of the corporation, no indemnification shall be made with respect to any matter
as to which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the adjudicating court determines that such
indemnification is proper under the circumstances.

        Article NINTH of Novavax's Amended and Restated Certificate of
Incorporation provides that a director or officer of the registrant (a) shall be
indemnified by the registrant against all expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement incurred in connection with any
threatened, pending or completed action, suit or other legal proceeding (other
than an action by or in the right of the registrant) to which he or she was or
is a party of is threatened to be made a party by virtue of his or her position
as a director or officer of the registrant if he or she acted in good faith and
in a manner he or she reasonably believed to be in, or not opposed to, the best
interests of the registrant, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful, and (b)
shall be indemnified by the registrant against all expenses (including
attorneys' fees) and amounts paid in settlement incurred in connection with any
threatened, pending or completed action or suit by or in the right of the
registrant to procure a judgment in the registrant's favor to which he or she
was or is a party of is threatened to be made a party by virtue of his or her
position as a director or officer of the registrant if he or she acted in good
faith and in a manner he or she reasonably believed to be in, or not opposed to,
the best interests of the registrant, except that no indemnification shall be
made with respect to any matter as to which such person shall have been adjudged
to be liable to the registrant, unless and only to the extent that the Delaware
Chancery Court determines that, despite such adjudication but in view of all of
the circumstances, he or she is entitled to indemnification of such expenses.
Notwithstanding the foregoing, to the extent that a director or officer has been
successful, on the merits or otherwise, including, without limitation, the
dismissal of an action without prejudice, he or she is required to be
indemnified by the registrant against all expenses (including attorneys' fees)
incurred in connection therewith. Expenses shall be advanced to a director or
officer at his or her request, provided that he or she undertakes to repay the
amount advanced if it is ultimately determined that he or she is not entitled to
indemnification for such expenses.

        Indemnification is required to be made unless the registrant determines
that the applicable standard of conduct required for indemnification has not
been met. In the event of a determination by the registrant that the director or
officer did not meet the applicable standard of conduct required for
indemnification, or if the registrant fails to make an indemnification payment
within 60 days after such payment is claimed by such person, such person is
permitted to petition the court to make an independent determination as to
whether such person is entitled to indemnification.





As a condition precedent to the right of indemnification, the director or
officer must give the registrant notice of the action for which indemnity is
sought and the registrant has the right to participate in such action or assume
the defense thereof.

        Article NINTH of Novavax's Amended and Restated Certificate of
Incorporation further provides that the indemnification provided therein is not
exclusive, and provides that in the event that the Delaware General Corporation
Law is amended to expand the indemnification permitted to directors or officers
the registrant must indemnify those persons to the fullest extent permitted by
such law as so amended. The registrant is also permitted to maintain insurance
to protect itself and any director, officer, employee or agent against any
expense, liability or loss incurred by him or her in any such capacity, or
arising out of his or her status as such, whether or not the registrant would
have the power to indemnify such person against such expense, liability or loss
under the Delaware General Corporation Law.

        The Company maintains insurance under which the insurers will reimburse
the registrant for amounts that it has paid to its directors and officers as
indemnification for claims against such persons in their official capacities.
The insurance also covers such persons as to amounts paid by them as a result of
claims against them in their official capacities that are not reimbursed by the
registrant. The insurance is subject to certain limitations and exclusions.

        Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers or persons controlling the
registrant pursuant to the foregoing provisions, or otherwise, the Company has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is therefore unenforceable.

Item 17. Undertakings.

        The undersigned registrant hereby undertakes:

        (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

                (i) To include any prospectus required by section 10(a)(3) of
        the Securities Act of 1933;

                (ii) To reflect in the prospectus any facts or events arising
        after the effective date of the registration statement (or the most
        recent post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information in the
        registration statement. Notwithstanding the foregoing, any increase or
        decrease in volume of securities offered (if the total dollar value of
        securities offered would not exceed that which was registered) and any
        deviation from the low or high end of the estimated maximum offering
        range may be reflected in the form of prospectus filed with the
        Commission pursuant to Rule 424(b) if, in the aggregate, the changes in
        volume and price represent no more than a 20% change in the maximum
        aggregate offering price set forth in the "Calculation of Registration
        Fee" table in the effective registration statement; and

                (iii) To include any material information with respect to the
        plan of distribution not previously disclosed in the registration
        statement or any material change to such information in the registration
        statement;

provided, however, that paragraphs (i) and (ii) above do not apply if the
registration statement is on Form S-3 or Form S-8, and the information required
to be included in a post-effective amendment by those paragraphs is contained in
periodic reports filed with or furnished to the Commission by the registrant
pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934
that are incorporated by reference in the registration statement.

        (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

        (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

        The undersigned registrant hereby further undertakes that, for purposes
of determining any liability under the Securities Act of 1933, each filing of
the registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

        Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
of 1933, as amended, and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question of whether such
indemnification by it is against public policy as expressed in said act and will
be governed by the final adjudication of such issue.





                                   SIGNATURES


        Pursuant to the requirements of the Securities Act of 1933, the
registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-3 and has duly caused this
Post-Effective Amendment No. 1 to Registration Statement to be signed on its
behalf by the undersigned, thereunto duly authorized, in the City of Columbia,
State of Maryland on November 12, 2003.
