      employment and severance protection agreements with Robert R. Nielsen, who
      succeeded Gerald J. Kitchen as Executive Vice President, General Counsel and
      Secretary of the Company effective May 1, 2006. Under the terms of his
      employment agreement, Mr. Nielsen will receive a base salary of $350,000 per
      annum and will be eligible to receive an annual performance-based cash bonus
      under the Company's incentive compensation plan of up to 100% of his base
      salary, subject to the discretion of the Compensation Committee. Mr. Nielsen's
      annual cash bonus for 2006 will be no less than $122,500. The agreement provides
      that Mr. Nielsen will receive options to purchase 25,000 shares of the Company's
      common stock and a one-time grant of 15,000 time vested performance shares.
      The
      options will vest over a period of two years, with one-third vesting on each
      of
      his employment date, the one year anniversary of his employment date and the
      two
      year anniversary of his employment date, and will be exercisable at an exercise
      price equal to the price of Century&#8217;s common stock on the last trading day
      immediately preceding his employment date. The shares of restricted stock will
      vest one-third each on the one, two and three year anniversaries of his
      employment date. Mr. Nielsen will also be eligible to participate in certain
      of
      Century&#8217;s incentive compensation and benefit plans, including our Amended and
      Restated 1996 Stock Incentive Plan, which provides for the award of options

      provides select senior executives with supplemental benefits in addition to

Item
      1.01. Entry into a Material Definitive Agreement
Effective
      May 1, 2006, Century Aluminum Company ("Century", "we" or "us") entered into
      employment and severance protection agreements with Robert R. Nielsen, who
      succeeded Gerald J. Kitchen as Executive Vice President, General Counsel and
      Secretary of the Company effective May 1, 2006. Under the terms of his
      employment agreement, Mr. Nielsen will receive a base salary of $350,000 per
      annum and will be eligible to receive an annual performance-based cash bonus
      under the Company's incentive compensation plan of up to 100% of his base
      salary, subject to the discretion of the Compensation Committee. Mr. Nielsen's
      annual cash bonus for 2006 will be no less than $122,500. The agreement provides
      that Mr. Nielsen will receive options to purchase 25,000 shares of the Company's
      common stock and a one-time grant of 15,000 time vested performance shares.
      The
      options will vest over a period of two years, with one-third vesting on each
      of
      his employment date, the one year anniversary of his employment date and the
      two
      year anniversary of his employment date, and will be exercisable at an exercise
      price equal to the price of Century's common stock on the last trading day
      immediately preceding his employment date. The shares of restricted stock will
      vest one-third each on the one, two and three year anniversaries of his
      employment date. Mr. Nielsen will also be eligible to participate in certain
      of
      Century's incentive compensation and benefit plans, including our Amended and
      Restated 1996 Stock Incentive Plan, which provides for the award of options
      and
      performance shares, and the Supplemental Retirement Income Benefit Plan, which
      provides select senior executives with supplemental benefits in addition to
      the
      benefits they are entitled to receive under our qualified retirement
      plans.
Under
      Mr.
      Nielsen's severance protection agreement, if Mr. Nielsen's employment is
      terminated within 36 months following a change in control of Century either:
      (i)
      by Century for any reason other than cause or disability, or (ii) by Mr. Nielsen
      for good reason, he will receive a lump sum payment equal to three times the
      aggregate of the highest base salary and the highest bonus received by Mr.
      Nielsen in any of the most recent five years. Also, upon a change in control,
      the exercisability of stock options and the vesting of performance shares held
      by Mr. Nielsen will be accelerated. The agreement also provides for additional
      payments to fully offset any excise taxes payable by Mr. Nielsen as a result
      of
      the payments and benefits provided for under the agreement.
The
      foregoing descriptions of the material terms of Mr. Nielsen's employment and
      severance protection agreements are qualified by reference to the full text
      of
      such agreements, which are attached hereto as Exhibits 10.1 and Exhibit 10.2,
      respectively.
On
      April
      29, 2006 our Compensation Committee approved a base salary of $325,000 for
      Mr.
      Gerald J. Kitchen, our former Executive Vice President, General Counsel, Chief
      Administrative Officer and Secretary. The new base salary is effective as of
      January 1, 2006. In addition, our Compensation Committee approved a cash bonus
      of $100,000 under Century's incentive compensation plan, for the portion of 2006
      Mr. Kitchen was our employee.
