PENSION PLANS

         On December 31, 1993, the Company froze its Defined Benefit Pension
Plan (the "Pension Plan"), which was replaced as of January 1, 1994, by the
Company's DC Plan. The Pension Plan was maintained for the benefit of employees,
except those covered by a collective bargaining agreement. Benefits under the
Pension Plan ceased to accrue after December 31, 1993.

         Annual benefits at age 65 for Messrs. Simko, Davis and Cougher under
the Pension Plan are frozen at $36,186, $33,500 and $15,901, respectively. The
years of credited service at December 31, 1993, for Mr. Simko, Mr. Davis and Mr.
Cougher were nine, ten and nine years, respectively. Employees who are age 55
and who have fifteen or more years of employment with the Company are eligible
for early retirement, and will receive approximately 75% of the accrued benefits
they would have received at age 65.

COMPENSATION OF DIRECTORS

         Directors who are not employees receive an annual retainer of $25,000
and $1,250 per day for each board and committee meeting attended. Directors who
so elect are covered by the Sunshine Mining Health Insurance Plan. During 1999,
directors received compensation as follows in cash and/or health benefits:
Messrs. Andersen $28,750, Babbitt $35,307, Elvin $28,750, Jackson $31,634,
Shaffer $28,750 and Smith $35,307.

EMPLOYMENT CONTRACTS

         Effective January 1, 1994, each of Messrs. Simko, Davis and Cougher
entered into written employment agreements (the "Employment Agreements") with
the Company for a term of three years. In December 1995, the Employment
Agreements for Messrs. Simko, Davis and Cougher were amended to extend the term
to December 31, 1999 and again in September 1998 to extend the term to December
31, 2002.

         In the event of the disability or death, the Employment Agreements
provide for the continued payment of the base compensation for the remaining
term, subject to reduction for disability payments separately provided by the
Company. The employees receive such annual incentive compensation based on the
performance of the Company or other criteria as may be awarded in the discretion
of the Board of Directors, and participate in any employee benefit, welfare,
deferred compensation, stock option plan, or any other plan or arrangement of
the Company now or hereafter adopted for the benefit of officers or employees
generally. In addition, Mr. Simko's agreement provides that he is deemed to have
qualified for early retirement under the Company's Pension Plan notwithstanding
that at the expiration of the agreement he shall have less than 15 years of
service with the Company.

         If within three years of a "change of control" of the Company,
employment of Messrs. Simko, Davis or Cougher is voluntarily or involuntarily
terminated, he is entitled to receive in a single payment an amount equal to two
times his base salary. In addition, he would continue to be paid the full amount
of compensation to which he would otherwise be entitled for the remaining term
of his employment agreement. All benefits under any employee benefit plan would
immediately vest and continue for the balance of the term of his agreement.

         The total amount of compensation (not including compensation for the
remainder of the term of the agreements) based on current base salaries which
would be required to be paid to each individual if his employment was terminated
upon a "change of control" of the Company would be $700,000, $480,000 and
$280,000 to Messrs. Simko, Davis and Cougher, respectively. Payments required
upon a "change of control" of the Company may be considered to have certain
anti-takeover effects in that they would make an acquisition of the Company more
costly.

         Pursuant to the Employment Agreements, the Company will indemnify each
employee in the event that he is made, or threatened to be made, a party to any
action or proceeding, including any action by or in the right of the Company by
reason of the provision of services by him to the Company. Claims or
controversies arising under the Employment Agreements will be resolved through
arbitration, and all resulting legal and accounting fees and other expenses will
be paid by the Company.
