On
      June
      28, 2006, the Board of Directors (the "Board") of Cougar Biotechnology, Inc.
      (the "Company") approved and adopted a non-employee director compensation
      program. Pursuant to the compensation program, effective June 28, 2006,
      non-employee directors are entitled to receive $2,500 for each meeting of the
      Board attended in person, and $500 for each meeting attended telephonically.
      Additionally, each non-employee director is entitled to receive an option grant
      to purchase 30,000 shares of the Company's common stock at an exercise price
      equal to the fair market value of the Company's common stock on the date of
      grant, such options to vest in equal parts annually over three years.
Pursuant

      each

      market value of the Company's common stock on the date of the grant, as
      determined by the Board in its good faith discretion. The options were issued
      under the Company's 2003 Stock Option Plan (the "Plan"). Such options, as
      amended, shall vest in three equal annual installments commencing on June

      Development, and Charles Eyler, the Company's Vice President of Finance. Each of

      Scientific Advisory Board. The option vests in equal annual installments over
      three years commencing on September 6, 2007.
