Naturally, you agree that all information concerning the Company's business will be treated as confidential.

BONUS I plan to install a Performance Bonus Plan at Apex covering the Calendar Year 1998 to be paid out according to the provisions of the Performance Bonus Plan when it is adopted which will undoubtedly occur after 1998. Mr. Gregory G. Marlier September 26, 1996 Page 3 3. BENEFITS Quite obviously a mining junior does not compete with a major mining company in terms of providing a complete comprehensive and top of the line benefit plan. However, I plan to install an appropriate personnel benefit plan for Apex's U.S. based executives at the earliest possible time. In that regard, as you may know, I recently commissioned Anderson & Schwab to conduct a compensation and benefit survey comprising juniors, intermediate and senior mining companies. I then asked A&S to recommend what they considered to be relevant competitive benefit plans that would be suitable for Apex. These plans, which are discussed below represent our present thinking on benefits that we plan to adopt for Apex. Although these plans are likely to be adopted, they have not yet been finalized. Apex' intent with regard to each benefit plan is as follows: Title of Plan Likely Apex Plan ------------- ---------------- Medical Plan HMO or PPO. If PPO: 80/20 coverage, deductible $200 per person, $400 per family, annual maximum $1,000 per person, $2,000 per family, $1,000,000 lifetime maximum. Dental Plan Either a plan with a $150 family deductible and $1,250 maximum annual benefit or a Dental HMO. Vision Plan None, but a Medical Reimbursement Account is contemplated, funded by the Company, that can be used for certain health care expenditures such as vision. Short-Term Disability 6 months full pay based on service. Mr. Gregory G. Marlier September 26, 1996 Page 4 Long-Term Disability 66% of pay up to $12K per month. Survivor Benefit Plan Probably won't have one Life Insurance Plan 2 x salary at $500K maximum AD&D Insurance Plan 2 x salary at $500K maximum Travel Accident Insurance Plan Covered by life insurance and AD&D insurance Savings Plan 401K plan or equivalent savings plan with company matching 50% of individual's contribution up to 6% of individual's salary up to a federally mandated cap, which is currently $150K. Increase in Apex's contributions to be considered when company is in production and has a positive cash flow. Pension Plan Some form of pension to be considered in the long-term future. Should you accept this offer of employment, it is our intent to work with you regarding your being covered under these plans in a timely way. This work will be done by A&S' Dick Hinkel, who is a career long human resources specialist whose prior assignment (for fifteen years) was as Vice President, Human Resources, for Homestake Mining. Dick took the lead in doing the compensation and benefits survey described above. 4. STOCK OPTIONS You will be eligible for participation in the Company's stock option plan. Thus, we will provide you with options on approximately $225,000 of stock of Apex Silver Mines Limited. The price of Apex's stock is based on the value of the company (US $160 million) as was determined by the recent successful completion of our private placement. . You will vest in these options over a four year period at 25 percent per year. Mr. Gregory G. Marlier September 26, 1996 Page 5 . You will be eligible to vest 25% immediately upon joining the Company, at which time you will be subject to the same shareholders' agreement entered into by all Apex's shareholders. V. OTHER 1. VACATION Four weeks vacation per year. 2. REIMBURSABLE EXPENSES . You will be reimbursed in accordance with company policy and guidelines for all reasonable expenses incurred in connection with travel on company business. .

As to class of travel, domestic travel will be coach and all international travel will be business class. . Frequent flyer miles will be the property of the user. 3. YOUR PAY Upon joining, and until Apex establishes a Denver office, you will be paid by wire to your bank account. 4. COMPANY OFFICE The company will establish a Denver office but it will take a while to do so. Until then the company will require that you work out of your home when you are in Denver. This, of course, means that if it will take a month or even longer before an office is established, that the company would expect you to put in a separate business telephone line and a fax machine for which they would reimburse you fully for both installation and use. If you find for this interim period your home to be an unacceptable place to work, then the company will arrange some type of interim office arrangements. Mr. Gregory G. Marlier September 26, 1996 Page 6 VI. SEVERANCE AGREEMENT In the event the Company should desire to terminate your employment, except for cause, within three years after your employment starting date, you will be entitled to severance pay for a twelve-month period at your existing salary, as well as a continuation of your benefits. Upon such an occurrence, bonus awards and stock options will be suspended. You agree that in the event you leave Apex that for a period of two years you will not join any company whose primary business is the acquisition and development of silver mines. * * * * I have enjoyed getting acquainted with you over the last several months. As a result of getting to know you, I believe that you can make a major contribution to our business and that you will find the work interesting and challenging.
