ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

Vesting of Performance Shares

      At a meeting held on March 21, 2005, the Compensation Committee of the
Board of Directors of Century Aluminum Company (the "Company") determined
vesting levels for performance shares previously awarded to eligible employees
under the Company's 1996 Stock Incentive Plan (the "1996 Plan") for the 2002 -
2004 performance period. Eligible employees include the following individuals,
each of whom who will be designated a Named Executive Officer in the Company's
2005 proxy statement (collectively, the "Named Executive Officers"): Craig A.
Davis, Chairman and Chief Executive Officer; Jack E. Gates, Executive Vice
President and Chief Operating Officer; Gerald J. Kitchen, Executive Vice
President, General Counsel, Chief Administrative Officer and Secretary; David W.
Beckley, Executive Vice President and Chief Financial Officer; and Daniel J.
Krofcheck, Vice President and Treasurer. Performance shares are awarded by the
Compensation Committee in accordance with established guidelines and represent
shares of the Company's common stock that, upon vesting, are issued to the award
recipient. In determining vesting levels, the Committee considered the extent to
which the Company achieved strategic, operating and financial targets
established by the Committee in 2002 for the 2002 - 2004 performance period.
Based on this assessment, the Committee set vesting at 65%, resulting in
performance share payouts for the Named Executive Officers in the following
amounts: Mr. Davis, 38,291 shares; Mr. Gates, 6,176 shares; Mr. Kitchen, 10,131
shares; Mr. Beckley, 10,023 shares; and Mr. Krofcheck, 5,166 shares.

2004 Cash Bonuses for Named Executive Officers

      Previously, the Compensation Committee approved cash bonuses for
executive officers under the Company's incentive compensation plan for the
year ended December 31, 2004 on the basis of the Company's performance and
the Compensation Committee's subjective evaluation of individual
performance.  The cash bonuses awarded to the Named Executive Officers for
2004 were as follows:  Mr. Davis, $ 1,810,000; Mr. Gates, $511,250; Mr.
Kitchen, $497,775; Mr. Beckley, $431,200; and Mr. Krofcheck, $341,700.

Board of Director Fees

   On March 21, 2005, the Compensation Committee determined the compensation to
be paid to each non-employee director for his service as a director of the
Company for the year ended December 31, 2005. For 2005, non-employee directors
will receive an annual retainer of $25,000 for their services, except for the
Chairman of the Audit Committee, who will receive an additional $5,000 for
serving in that capacity. In addition, each non-employee director will receive a
fee of $2,000 for each Board or Board Committee meeting attended, except for the
Chairman of the Audit Committee, who will receive $3,000 per Audit Committee
meeting attended. All directors will be reimbursed for their travel and other
expenses incurred in attending Board and Board Committee meetings. Under the
Company's Non-Employee Directors Stock Option Plan, each non-employee director
continuing in office after the annual meeting of stockholders will also receive
options to purchase 3,000 shares of the Company's common stock at an exercise
price equal to the market price of such shares on the date of the grant.


                                       2

Amendment to Employment Agreement for David W. Beckley

      On March 21, 2005, the Compensation Committee approved an amendment to the
employment agreement for David W. Beckley, Executive Vice President and Chief
Financial Officer of the Company. Under the amendment, Mr. Beckley will continue
to serve as Executive Vice President and Chief Financial Officer until his
retirement on December 31, 2005 and will be available to act as a consultant to
the Company thereafter. The amendment provides that Mr. Beckley will be paid a
special bonus in early 2006 equal to 50% of his base pay at the time of his
retirement.

      ITEM 5.02 DEPARTURE OF DIRECTORS OR PRINCIPAL OFFICERS; ELECTION OF
DIRECTORS; APPOINTMENT OF PRINCIPAL OFFICERS

      (b) David W. Beckley has informed the Company that he plans to retire as
Executive Vice President and Chief Financial Officer of the Company on December
31, 2005. Mr. Beckley has agreed to be available to act as a consultant to the
Company following his retirement.
