          NOVAVAX, INC. SUBMITS NEW DRUG APPLICATION FOR ESTRASORB(TM),
            A NOVEL TRANSDERMAL, TOPICAL ESTROGEN REPLACEMENT THERAPY

                  JOHN SPEARS STEPS DOWN AS PRESIDENT AND CEO,
              COMPANY INITIATES EXECUTIVE SEARCH FOR A REPLACEMENT


COLUMBIA, MD, SEPTEMBER 9, 2002 - NOVAVAX, INC. (NASDAQ: NVAX) today announced
that on September 9, 2002 the Company submitted a New Drug Application (NDA)
with the U.S. Food and Drug Administration (FDA) for ESTRASORB(TM).
ESTRASORB(TM), an estradiol topical emulsion, is an estrogen-only lotion-like
formulation being developed for short-term use in the reduction of vasomotor
symptoms, such as hot flushes, in menopausal women. The submission comes less
than five months after the FDA requested additional information with respect to
the Chemistry Manufacturing and Controls (CMC) section of the Company's initial
NDA filing.

"Since voluntarily withdrawing our initial NDA in April 2002, we have worked
diligently to generate and compile the information necessary to finalize this
submission," commented Dr. Denis O'Donnell, Chairman of the Board of Directors
of Novavax, Inc. "Additional laboratory work included validating a stability
indicating method and performing content uniformity testing. We are pleased to
have been able to complete this work in a timely manner and we believe the
submission should satisfactorily answer the FDA's CMC questions. It is important
to note that during the initial review process the review division communicated
no concerns regarding the efficacy or safety of ESTRASORB(TM). This makes us
hopeful that the enhanced submission will ultimately lead to a favorable review
by the FDA."

Dr. O'Donnell added, "While recently publicized studies have questioned the
long-term administration of hormone replacement therapy (HRT) products, we
continue to believe ESTRASORB(TM), which contains estrogen alone, may offer
significant potential, particularly given our novel topical delivery mechanism
and recommended short-term therapy. In particular, ESTRASORB(TM) differs from
the products used in the National Institutes of Health (NIH) Women Health
Initiative study in the following ways: (1) ESTRASORB(TM) utilizes a proprietary
transdermal delivery system, as opposed to oral administration; (2)
ESTRASORB(TM) contains a synthetic estrogen that is identical to the estrogen
women produce naturally, as opposed to conjugated equine estrogens combined with
a synthetic progestin; and (3) ESTRASORB(TM) is being evaluated for short-term
use for the relief of vasomotor symptoms associated with menopause, as opposed
to the long-term administration of HRT products in the NIH study."

Novavax and King Pharmaceuticals, Inc. have a co-promotion agreement for
ESTRASORB(TM) in the U.S. and Puerto Rico, while King has exclusive marketing
rights for ESTRASORB(TM) outside the U.S.

MANAGEMENT CHANGES
Separately, Novavax announced that John Spears has stepped down from the
positions of President, CEO and Director of the Company. Working closely with
the other members of the Executive Committee of the Board of Directors, which
includes Dr. O'Donnell, Gary C. Evans and Michael A. McManus, Mitchell J. Kelly
will serve as President and CEO on an interim basis until an executive search is
completed for a new CEO. Mr. Kelly previously served in those positions from
September 1998 until May 1999 and is the CEO of Anaconda Capital Management,
L.L.C. (ACM), an affiliate of which owns 9.1% of the outstanding common shares
of Novavax.

"Novavax is very grateful for John Spears' nearly three and one-half years of
service to the company. We are particularly thankful for the excellent work he
performed in leading the re-submission of the NDA for ESTRASORB(TM)," said Dr.
O'Donnell. "We are very hopeful that the Company has effectively answered the
FDA's prior CMC questions with regard to ESTRASORB(TM) and we are even more
excited about the potential for ESTRASORB(TM) in the HRT arena."

In addition, Novavax announced that James Mirto has resigned as Senior Vice
President and Chief Operating Officer. The Company does not anticipate, in the
near term, that it will seek a new COO.
