Item 1.01 Entry into a Material Definitive Agreement.

               On December 6, 2005, the Board of Directors of Pharmion
          Corporation (the "Company"), upon the recommendation of its
          Compensation Committee, approved the acceleration of the vesting of
          certain "out-of-the-money" unvested incentive and non-qualified stock
          options granted to employees of the Company prior to April 1, 2005
          with option exercise prices equal to or greater than $21.00 per share.
          This acceleration is effective as of December 6, 2005 and represents
          options exercisable for a total of 839,815 shares of the Company's
          common stock, including a total of 275,941 shares of the Company's
          common stock underlying options held by "named executive officers" of
          the Company as identified in the Company's Proxy Statement dated April
          29, 2005. All other terms and conditions applicable to outstanding
          stock option grants remain in effect.

               The Board of Directors made the decision to approve the
          acceleration of the vesting of the affected stock options described
          above primarily to reduce the non-cash compensation expense that would
          have been recorded in future periods, following the effectiveness of
          the Financial Accounting Standards Board's Statement of Financial
          Accounting Standards No. 123 (Revised 2004) ("FAS 123(R)"). FAS 123(R)
          will require the Company to treat its unvested stock options as an
          expense. Pursuant to Securities and Exchange Commission Rule 4-01(a)
          of Regulation S-X, the Company is required to adopt FAS 123(R)
          beginning in the first fiscal quarter of 2006. As a result of the
          acceleration of the vesting of the options described above, the
          Company estimates that it will eliminate approximately $16 million of
          future non-cash compensation expense (before tax) over the period
          during which the stock options would have vested.
