PRESS RELEASE: Medivation Secures $100 Million Committed Equity Financing Facility

Medivation Secures $100 Million Committed Equity Financing Facility

SAN FRANCISCO, Sept 10, 2007 - Medivation today announced that it has obtained a committed equity line of credit facility under which it may sell up to $100 million of its registered common stock to Azimuth Opportunity, Ltd. over an 18-month period. Medivation is not obligated to utilize any of the $100 million facility and remains free to enter other financing transactions. Medivation did not pay a commitment fee, or issue any warrants, to secure this facility.

Medivation will determine, at its sole discretion, the timing, dollar amount and floor price per share of each draw under this facility, subject to certain conditions. The number and price of shares sold in each draw are determined by a contractual formula designed to approximate fair market value, less a small discount. Any shares sold under this facility will be sold pursuant to a shelf registration statement declared effective by the Securities and Exchange Commission on August 20, 2007.

"As we prepare to begin our global Phase 3 Alzheimer's disease trials next year, this extremely flexible facility is an important addition to our menu of financing options," said Patrick Machado, senior vice president and chief financial officer of Medivation. "It gives us the ability to raise capital quickly and at a competitive cost, and to manage dilution more effectively by issuing shares in multiple tranches at times of our choosing over the next eighteen months. We believe these advantages will be of significant benefit to Medivation and our shareholders as we continue to execute our business plan."

This press release shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any state.
