Marshall Edwards, Inc. Joins Russell 3000® Index

NEW CANAAN, CT--(Marketwire - June 26, 2008) - Marshall Edwards, Inc. (NASDAQ: MSHL), a clinical-stage biotechnology company developing a new class of oncology drugs known as "multi-signal transduction regulators," today announced that it is soon to be included in the Russell 3000® Index, according to a preliminary list of additions recently posted on www.russell.com. Marshall Edwards, Inc.'s addition to the broad market Russell 3000® Index, which remains in place for one year, means automatic inclusion in the Russell 2000® Index. The 2008 reconstitution of the Russell indexes will take place after the market closes on June 27, 2008.

"With our lead drug candidate phenoxodiol in a pivotal phase III trial for recurrent ovarian cancer, the Russell 3000® Index has recognized our potential," said Christopher Naughton, President and Chief Executive Officer. "Marshall Edwards, Inc.'s inclusion in the Russell 3000® Index offers us visibility to more investors."

The Russell 3000® Index measures the performance of the largest 3,000 U.S. companies based on total market capitalization, representing approximately 98% of the investable U.S. equity market according to Russell Investments. The Russell 2000® Index is a subset of the Russell 3000® Index representing approximately 10% of the total Market capitalization of that index and includes approximately 2,000 of the smallest securities based on a combination of their market capitalization and current index membership in the Russell 3000® Index.

About phenoxodiol:

Phenoxodiol is being developed as a chemosensitizing agent in combination with platinum drugs for late stage, chemoresistant ovarian cancer and as a monotherapy for prostate and cervical cancers. It has a unique mechanism of action, binding to cancer cells via a cell membrane oxidase, causing major downstream disturbances in expression of proteins necessary for cancer cell survival and responsible for the development of drug resistance.

In cancer cells, phenoxodiol appears to selectively inhibit the regulator known as S-1-P (sphingosine-1-phosphate) that is overexpressed in cancer cells. In response to phenoxodiol, the S-1-P content in cancer cells is decreased, with a consequent decrease in expression of the pro-survival proteins XIAP and FLIP, rendering those cells more sensitive to chemotherapy. Indeed, in laboratory studies, it has been demonstrated that drug-resistant ovarian cancer cells pre-treated with phenoxodiol were killed with lower doses of chemotherapy drugs.

Importantly, phenoxodiol has been shown not to adversely affect normal cells in animal and laboratory testing.

Phenoxodiol is being investigated as a therapy for late-stage, chemoresistant ovarian, prostate and cervical cancers. Phenoxodiol has received Fast Track status from the FDA to facilitate its development as a therapy for recurrent ovarian and prostate cancers.

Phenoxodiol is an investigational drug and, as such, is not commercially available. Under U.S. law, a new drug cannot be marketed until it has been investigated in clinical trials and approved by FDA as being safe and effective for the intended use.

Phenoxodiol is the first of a family of compounds in the Marshall Edwards, Inc. drug pipeline of flavonoid derivatives.

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, Inc. has licensed rights from Novogen Limited (ASX: NRT) (NASDAQ: NVGN) to bring three oncology drugs -- phenoxodiol, triphendiol and NV-143 -- to market globally. The Company's lead investigational drug, phenoxodiol, is in a Phase III multinational multi-centered clinical trial for patients with recurrent ovarian cancer. More information on the trial can be found at http://www.OVATUREtrial.com.

Marshall Edwards, Inc. is majority owned by Novogen Limited (ASX: NRT) (NASDAQ: NVGN), 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.
