September 16, 2009 indicating that the Company failed to comply with the minimum bid price

the Company s common stock had to remain at or above $1.00 per share for a minimum of 10
consecutive business days prior to the market close on March 15, 2010. The Company
did not regain compliance with the $1.00 minimum bid price requirement by such time, which resulted
in the issuance of the Staff Determination

Edwards is in full compliance with Nasdaq s listing rules. The reverse stock split is subject to

About Marshall Edwards, Inc.
Marshall Edwards, Inc. is a specialist oncology company focused on the clinical development of
novel anti-cancer therapeutics. These derive from a flavonoid technology platform, which has
generated a number of novel compounds characterized by broad ranging activity against a range of
cancer cell types with few side effects. The combination of anti-tumor cell activity and low
toxicity is believed to be a result of the ability of these compounds to target an enzyme present
in the cell membrane of cancer cells, thereby inhibiting the production of pro-survival proteins
within the cell. Marshall Edwards has licensed rights from Novogen Limited (ASX: NRT NASDAQ: NVGN)
to bring four oncology drugs phenoxodiol, triphendiol
NV-143 and NV-128 to market globally.
Marshall Edwards is majority owned by Novogen, an Australian biotechnology
company that is specializing in the development of therapeutics based on a flavonoid technology
platform. Novogen is developing a range of therapeutics across the fields of oncology,
cardiovascular disease and inflammatory diseases. More information on phenoxodiol and on the
Novogen group of companies can be found at www.marshalledwardsinc.com and www.novogen.com.
