The Non-Employee Directors' Share Plan provides for the automatic grant of (i) a fully vested and exercisable option to purchase a number of ordinary shares equal to $50,000 divided by the closing price of the ordinary shares on the American Stock Exchange on the date of the grant to each non-employee director at the effective date of his or her initial election to the board of

8



directors, (ii) a fully vested and exercisable option to purchase the number of ordinary shares equal to $50,000 divided by the closing price of the ordinary shares on the American Stock Exchange on the date of the grant at the close of business of each annual meeting of the shareholders, and (iii) at the close of business of each meeting of the board of directors, a fully vested and exercisable option valued at $3,000 calculated using the Black-Scholes option-pricing model to purchase ordinary shares with an exercise price equal to the closing price of the ordinary shares on the American Stock Exchange on such date, without regard to whether the non-employee director attends the meeting. During 2004, pursuant to the Non-Employee Directors' Share Plan, non-employee directors received as standard compensation the following options to purchase our ordinary shares:

Date of 2004 Grant

  Number
of Shares

  Exercise Price
January 23   411   $ 21.41
February 27   400   $ 21.83
March 11   406   $ 21.50
May 27   3,251   $ 18.65
September 30   466   $ 21.70
October 7   472   $ 21.00
December 9   595   $ 16.68

        In addition, non-employee directors are paid $600 for attendance at board meetings and $500 for attendance at board committee meetings. We also reimburse our directors for all reasonable out-of-pocket costs incurred by them in connection with their services to us.

        Mr. Hansard performs consulting services for Moore Capital Management, LLC. One or more investment portfolios managed by Moore Capital or its affiliates are shareholders of Apex Silver. For these consulting services and for time spent attending meetings of our board of directors, Moore Capital compensates Kingsfort Ltd., of which Mr. Hansard is an employee, 45,000 Great British Pounds per annum, and directly compensates Mr. Hansard 20,000 Great British Pounds per annum. Amounts paid by Moore Capital directly or indirectly to Mr. Hansard for attending our board meetings totaled approximately $121,000 for 2004. Mr. Hansard may assign to Moore Capital's clients, who are shareholders of Apex Silver, ordinary shares he receives on the exercise of options granted to him as director compensation.

Employment Agreements and Change-in-Control Arrangements

        At the time we offered employment to Messrs. Hulley, Clevenger, Edwards and Lettes, we provided each executive officer with a letter indicating the terms of his employment with Apex Silver. All executives are employed on an at-will basis and may be terminated at any time. Under the terms of their offer letters, Messrs. Hulley, Clevenger, Edwards and Lettes each have agreed not to join a company whose primary business is the acquisition and development of silver mines for two years after termination of employment with us.

        We have also entered into change of control agreements with Messrs. Hulley, Clevenger, Edwards and Lettes. The agreements become effective upon a change of control as defined in the agreements. If we terminate an executive other than for cause, disability or death or the executive terminates his employment for good reason (as such terms are defined in the agreements), the executive will become entitled to a specific severance payment equal to three times, for Messrs. Hulley, Clevenger and Edwards, and two times, for Mr. Lettes, the sum of the executive's base salary plus 100 percent of the executive's target bonus amount (as defined in our incentive bonus plan) multiplied by the executive's annual base salary. The agreements provide that if any payments under the agreements would cause us to have paid an "excess parachute payment" as defined in Section 280G(b)(1) of the Internal Revenue Code, the payment will be reduced to the highest amount that will not cause us to have paid an excess

9



parachute payment. In addition, if we terminate the executive other than for cause, disability or death or the executive terminates his employment for good reason, the executive shall be entitled, for a 36 month period for Messrs. Hulley, Clevenger and Edwards, and for a 24 month period for Mr. Lettes, to certain life, disability, accident, medical and dental insurance benefits.

        We have adopted a severance plan which provides benefits to employees who cease to be employed by us due to involuntary termination without cause. As defined in the plan, involuntary termination without cause includes job elimination or consolidation, closure of a work site, reorganization or merger or reduction in work force, and does not include disability, retirement or voluntary resignation. Messrs. Hulley, Clevenger, Edwards and Lettes are eligible to participate in the plan. Under the plan, unless otherwise agreed as described below, each executive would receive severance pay based on his years of continuous employment, with a minimum of 16 weeks of pay and a maximum of 52 weeks of pay, plus medical, dental, life insurance, outplacement and other benefits. If upon termination of an executive's employment he receives benefits under his change of control agreement, he would not receive benefits under the severance plan.

        Our 2004 Equity Incentive Plan, pursuant to which Messrs. Hulley, Clevenger, Edwards and Lettes hold options, provides that in the event of a change in control (as defined in the 2004 Equity Incentive Plan), all unvested options become exercisable in full.

Compensation Committee Interlocks and Insider Participation

        Neither Mr. Conger nor Mr. Soros, the members of the Compensation Committee in 2004, has ever been an officer or employee of Apex Silver or its subsidiaries. All relationships between these directors and Apex Silver and its subsidiaries required to be disclosed have been disclosed elsewhere in this annual report on Form 10-K, as amended.
