Item
      1.01 Entry into a Material Definitive Agreement
Amendment
      and Restatement of Implementation Guidelines
At
      a
      meeting held on June 8, 2006, the Compensation Committee (the "Committee") of
      the Board of Directors (the "Board") of
Century
      Aluminum Company ("Century") amended and restated the Implementation Guidelines
      (the "Guidelines") for Century's Amended and Restated 1996 Stock Incentive Plan
      (the "Plan"). The Guidelines, which are discretionary, provide guidance for the
      Committee when making awards of performance shares under the Plan. The
      amendments to the Guidelines (i) effect ministerial changes, (ii) add senior
      vice presidents to the classes of employees eligible for awards, and (iii)
      change from one month to 60 trading days the period of time used for determining
      the average closing price for Century's common stock for purposes of setting a
      participant's performance share award levels.
The
      foregoing description is qualified by reference to the full text of the Amended
      and Restated 1996 Stock Incentive Plan Implementation Guidelines, which is
      attached hereto as Exhibit 10.1.
Amendment
      and Restatement of Incentive Compensation Plan
On
      June
      9, 2006, the Board approved the amendment and restatement of Century's Incentive
      Compensation Plan, as recommended by the Committee. Under the Incentive
      Compensation Plan, participants are eligible to receive each year as a
      discretionary bonus, a percentage of their base salary. The amendments approved
      by the Board will (i) expand the classes of employees eligible for awards to
      include senior vice presidents, and (ii) effect other ministerial and conforming
      changes.
The
      foregoing description is qualified by reference to the full text of the Amended
      and Restated Incentive Compensation Plan, which is attached hereto as Exhibit
      10.2.
