                             ARTICLES OF AGREEMENT

This Agreement is between Stillwater Mining Company ("Company"), its successors
and assigns, and the Paper, Allied Industrial, Chemical and Energy Workers
International Union and its Local 8-001 ("Union"), its successors and assigns.


                                   ARTICLE 1
                                  RECOGNITION

Section 1.  The Company recognizes the Union as the sole and exclusive
bargaining representative for the following Company employees employed by the
Company at the facilities at [insert address], Nye, Montana; and the facilities
at [insert address], Columbus, Montana.  All hourly production and maintenance
employees, including warehouse employees, laboratory technicians and custodians;
but excluding all temporary employees, student summer hires, professional
employees, technical employees, office clerical employees, guards, dispatchers
and supervisors, and those above the rank of supervisor.

Section 2.  The Union's Workers' Committee represents Union interests to the
Company.  The Workers' Committee will be selected by the Union, and consist of
seven (7) members, including the Local Union President who will be Chair.  The
six (6) remaining members will consist of three (3) from the Mine, one (1) from
the Concentrator, one (1) from the Smelter/BMR/Laboratory, and one (1) from
Maintenance/Warehouse.  Alternates may be selected to replace absent Committee
members.

Section 3.  The Local Union President will promptly notify the Company, in
writing, of the names of the Workers' Committee members, the Grievance Committee
members and any selected stewards.  The Company will be notified, in writing, of
any changes to these groups.

Section 4.  The activities of the Union's Workers' Committee will not result in
any disruption of the Company's operations, and employees will not neglect their
duties and responsibilities.

                                  ARTICLE 2
                              NON-DISCRIMINATION

Section 1.  The Company and Union agree that neither will discriminate nor
harass any employee or applicant for employment because of race, creed,
<PAGE>

marital status, color, age, disability, religion, national origin or sex in
violation of any applicable Federal, State or local law.

                                   ARTICLE 3
                                UNION SECURITY

Section 1.  Every employee covered by this Agreement must, for the life of this
Agreement after the grace period described below, satisfy a financial obligation
to the Union as the exclusive bargaining representative.  Under this Agreement,
the financial obligation for union members is an amount equivalent to monthly
dues, and for non-members a fee amount, as determined by the Union, to perform
the duties as exclusive representative under this Agreement.

   This financial obligation is a condition of continued employment and is in
consideration for the cost of representation and collective bargaining and is
not contingent upon present or future membership in the Union.

   The grace period for this Agreement is thirty (30) calendar days following
the completion of the employee's probationary period or by the thirtieth (30th)
calendar day following the effective date of this Agreement, whichever is later.

   Neither the Union, Company, nor any of their officers, agents or members will
intimidate or coerce employees about membership or non-membership in the Union.
If any dispute arises as to whether there has been any violation of this
provision (or whether an employee affected by this Agreement has failed to meet
the financial obligation), the dispute will be submitted directly to arbitration
for determination.

   The Union will indemnify and save the Company harmless against any and all
claims, demands, suits or other forms of liability that will arise out of or by
reason of action taken by the Company in complying with the provisions of this
Article.

Section 2.  For employees in the bargaining unit, the Company agrees to deduct
the Union dues for the month from the wages due each month, providing each
employee from whose check Union dues are to be deducted has on file a signed
payroll deduction authorization.

                                   ARTICLE 4
                               MANAGEMENT RIGHTS

Section 1.  Management retains all the general and traditional rights to manage
the business as well as any rights under law or agreed to by the parties.  These
rights rest exclusively in management who are the sole decision makers regarding
the Company's operations.  The following listing of specific management rights
is not intended to be all-inclusive, but are some of those rights considered to
be general rights of management.  The fact that a particular management right is
not included in the following listing does not
<PAGE>

mean the right does not exist.

Section 2.  The Company has the right to determine the number of employees
required by the Company at any place from time to time, for any and all
operations; to determine the jobs, content of jobs and to modify, combine or end
any job, classification, department or operation; to hire, classify, transfer,
promote, demote and layoff employees; to determine qualifications, evaluate
performance and assign and direct the workforce; to maintain order and
discipline; and to reprimand, suspend, discharge and otherwise discipline for
just cause.

Section 3.  The Company has the right to create and administer rules, policies
and procedures.  This will include the right to establish or revise attendance,
work, substance abuse, drug and/or alcohol testing, functional testing and
safety rules.  The Company has the right to establish or revise a disciplinary
policy to address violations of these rules.

Section 4.  The Company also has the right to determine the number and types of
facilities and working places; the kinds and locations of machines, tools and
equipment to be used; and the right to schedule production; to maintain
efficiency; to introduce new or improved research methods, materials, processes,
techniques, machinery and equipment, means of processing, distribution and
mining; to set the standards of productivity and the products to be produced; to
determine employees' working schedules, including, but not limited to, the
number of hours and shifts to be worked; to determine when overtime work is
necessary and to assign overtime; to choose customers; to utilize part-time and
temporary employees; to decide where or when training on a particular operation
or job is required, how much training is required and the right to move or
retrain employees;  to determine the amount and form of any incentive and/or
bonus compensation to be paid in addition to wages; to establish, implement,
modify, suspend or terminate any contract or incentive program; to use
independent contractors to perform any work or services.

Section 5.  The Company's failure to exercise any right or function reserved to
it, or the exercise of a management right in a particular way,  will not prevent
the Company from exercising any of its rights in the future or in some other way
not in conflict with this Agreement.  The only restrictions on management rights
are those expressly provided for in this Agreement.

Section 6.  The exercise of these rights alleged to be in conflict with any
other provision of this Agreement will be subject to the grievance and
arbitration procedures.

                                   ARTICLE 5
<PAGE>

                          MANAGEMENT-UNION COMMITTEE

Section 1.  The Company and the Union recognize the benefits of an open forum
where information, mutual concerns, interests, and complaints (not covered by
the grievance and arbitration procedures) affecting the workplace can be freely
discussed, with a view to exploring possible solutions which are acceptable and
beneficial to employees, the Union and the Company.  Without limiting the
opportunity for the Union and the Company to meet informally at the Nye or
Columbus facilities, the parties agree to establish a Management-Union Committee
(MUC).

Section 2.  The Workers' Committee will serve as representatives for the Union
at MUC meetings.  The Company representatives will be comprised of Senior
Management personnel.

Section 3.  MUC meetings will normally be held during regular business hours,
as necessary, on at least a quarterly basis.  Logistics for the meeting will be
mutually agreed upon and coordinated through the Human Resources Department.
Senior Management from the Nye and Columbus facilities will discuss agenda items
with the Local Union President prior to the meeting.  A formal meeting agenda
will be given to all Committee members at least five (5) days prior to the
meeting, whenever possible.

Section 4.  For employees on their regularly scheduled shifts, time spent at
MUC meetings will be considered as time worked and will be paid at an employee's
normal base rate.  The Company will make every reasonable effort to schedule the
MUC members on shift during MUC meetings.

Section 5.  The MUC is limited to joint discussion and consultation, and is not
intended to limit or restrict the rights reserved to the Union or the Company by
this Agreement.  The Committee is not intended to take the place of normal
communication between employees and the Company, or to serve as an alternative
to the grievance and arbitration procedures of this Agreement.

                                   ARTICLE 6
                           GRIEVANCE AND ARBITRATION

Section 1.  Dispute(s) between the Company and its employees may occur.
Employees are encouraged to settle these differences as quickly as possible with
their immediate foreman or supervisor.  If desired, the employee may be
accompanied and assisted by a steward or Grievance Committee member.  A
"grievance" is a dispute as to the interpretation, application, or alleged
violation of any of this Agreement's provisions.
<PAGE>

Section 2.  The Union will establish a Grievance Committee for dealing with
grievances for each of the following departments: Mine, Concentrator,
Maintenance/Warehouse and Smelter/BMR/Laboratory.  The Union will select up to
three (3) employees to serve on the Grievance Committees from each of the above
departments.  The Local Union President will be a member of each of the
Grievance Committees.

Section 3.  Failure by the Union to transmit a grievance to the next higher step
within the time limit provided will constitute a settlement of that grievance on
the basis of the last answer received.  If the Company's decision at any step of
this procedure is not given within the time limit specified, the grievance will
be upheld for the Union.  The time limits in this Article may be extended by
mutual agreement.  The Company will pay for time spent by union representatives
in grievance meetings that are scheduled during their regular working hours.

Section 4.   If a grievance arises that is not verbally settled with the
immediate supervisor, an earnest effort will be made to settle the grievance in
the following manner:

     Step 1:  Within fifteen (15) days from the time the grievance arose, the
     employee (or steward or Grievance Committee member) will present the
     grievance, in writing, using the standard grievance form, to the immediate
     supervisor, with a copy to the Human Resources Manager and the Local Union
     President.  The employee may be assisted by a member of the Grievance
     Committee or a steward, if so desired.  The supervisor will give a written
     reply within seven (7) days of this meeting.

     Step 2:  Failing satisfactory resolution at Step 1, the matter may be
     presented to the grievant's Department Head, with a copy to the Human
     Resources Manager, within ten (10) days of the immediate supervisor's
     decision.  The Department Head will convene a meeting with the employee, a
     steward or Grievance Committee member, and a Human Resources
     Representative, within ten (10) days of notification from the Union, for
     the purpose of resolving the grievance.  The Department Head will give a
     written reply within seven (7) days of the meeting.

     Step 3:  Failing satisfactory resolution at Step 2, the matter may be
     presented to a Company Vice President, with a copy to the Human Resources
     Manager, within ten (10) days of the Department Head's decision, with a
     request that a meeting be held with a Vice President for the purpose of
     resolving the grievance.  A Vice President will convene a meeting with the
<PAGE>

     Grievance Committee, the Local Union President, the steward who filed the
     grievance, a representative from the Human Resources Department and another
     management representative.  The meeting will be held within fourteen (14)
     days from the time the matter is submitted to a Vice President.  A Vice
     President will render a written decision to the Local Union President
     within ten (10) days of the meeting.

Section 5.  Following Step 3, the parties may refer a grievance to a mediator
acceptable to both parties.  There will be a maximum of three (3) grievances
submitted to binding arbitration per hearing.  The cost of the mediator will be
paid equally by both parties.

Section 6.  If the Union disagrees with the decision rendered by the Vice
President, it may, within thirty (30) days from the date of the decision, refer
the grievance to the Federal Mediation and Conciliation Service.  The parties
will request the Federal Mediation and Conciliation Service to submit a panel of
seven (7) arbitrators.  Each party will have the right to reject one panel of
arbitrators.  The Union will strike the first name and then the parties will
alternately strike a name until one arbitrator is left.  The arbitrator will be
notified of selection by a letter from the parties requesting that the
arbitrator set a time for the hearing.

Section 7.  If any grievance proceeds beyond Step 3, the grieving party must
submit in writing all known evidence bearing on the grievance. This includes,
but is not limited to, a description of the practice or matter giving rise to
the dispute, relevant dates and all witnesses, along with the specific contract
clause that is allegedly being violated. Evidence not disclosed according to
this section cannot be introduced by the grieving party at arbitration. Evidence
that is discovered at a later date may be introduced at hearing if disclosed to
the Company in writing at least five (5) days prior to the arbitration.

Section 8.  In rendering a decision, the arbitrator will be governed and limited
by this Agreement's provisions, applicable law, and the expressed intent of the
parties as described in this Agreement.  The arbitrator will have no power to
add to, subtract from, or modify any of the terms and provisions of this
Agreement, or substitute his judgment for that of the Company.  The arbitrator
will confine his judgment strictly to the facts submitted in the hearing, the
evidence before him, and this Agreement's express terms and provisions.  The
arbitrator's decision will be final and binding upon the parties.

Section 9.  The cost of the arbitrator will be paid equally by the parties.

Section 10. The Union and the employees waive their right to pursue any
judicial or administrative remedy against the Company as to any matter subject
<PAGE>

to the procedures established in this Article until such procedures are
exhausted.  Any settlement under the procedures established under this Article,
short of arbitration, will be binding upon the Company, the Union, and the
employees and will preclude any further administrative or judicial relief.

Section 11.  Any employee has the right to have a union representative present
if they are called into a meeting which may result in disciplinary action.

Section 12.  If it is necessary for a steward or Grievance Committee member to
take time off during their regularly scheduled shift to investigate or resolve a
grievance, they will request the permission of their immediate supervisor which
will not be unreasonably withheld.  When a steward or Grievance Committee member
enters an area other than their normal work area, they will inform the
supervisor of that area of their presence and reason for being there.  A steward
or Grievance Committee member will inform their supervisor when returning to
their normal work area.

Section 13.  Grievances dealing with discharges will be moved immediately to
Step 2 of the grievance procedure.

Section 14.  The Union, by not exercising any functions reserved to it or by
exercising any function in a particular way, will not be deemed to have waived
its right to exercise functions as set forth in this Agreement.

                                   ARTICLE 7
                              MEDICAL ARBITRATION

Section 1.  In the event a dispute arises concerning the physical fitness of an
employee to return to work or to continue to work, an attempt to resolve the
dispute by conference or consultation between a licensed physician selected by
the Company and a licensed physician selected by the Union, will first be made.

Section 2.  If no satisfactory conclusion is reached and the Union or the
Company so elects, a Board of three (3) licensed physicians will be selected,
one by the Company, one by the Union, and one by the two so-named, who will
decide the case.  The decision of the Board will be final and binding on both
parties to this Agreement and retroactive to the date the dispute arose.

Section 3.  The Company will bear the expense of the physician of its choice,
and the Union will bear the expense of the physician of its choice.  The expense
of the third physician will be paid by the losing party.  In the event that the
decision of the Board does not result in a clear-cut losing party, the expense
of the third physician will be paid equally by the parties.

                                   ARTICLE 8
                                   SENIORITY

Section 1.  Company seniority will be determined by an employee's date of
original employment with the Company, if there has been no service break.
Company seniority will apply only for purposes of applicable benefit plans and
earned vacation.

Section 2.  Plant seniority will be determined from the employee's date of
original employment with the Company at its facilities covered by this Agreement
or date of employment if there had been a break in service.  An employee's plant
seniority will be lost if the employee:

   A.       Quits.
   B.       Is discharged for just cause.
   C.       Fails to work for any reason for two (2) years, or length of
            service, whichever is less.
   D.       Fails to return to work upon termination of a leave of absence.
   E.       Is promoted to a full-time non-bargaining unit position for a period
            in excess of one (1) year.

Section 3.  Department seniority will be determined by the date on which the
employee begins continuous service in one of the following departments:

   A.       Mine
   B.       Concentrator
   C.       Maintenance
   D.       Warehouse
   E.       Processing (Smelter/BMR/Laboratory)

The employee will lose department seniority in any previous department once
department seniority is established in any other department.

Section 4.  The Company will annually provide the Union with a current seniority
list which will also be posted in the workplace.

Section 5.  If employees are hired on the same day, seniority will be decided
by the flip of a coin.

                                   ARTICLE 9
                              PROBATIONARY PERIOD

Section 1.  All new employees will be considered probationary employees for
<PAGE>

a period of seven hundred eighty (780) hours worked. The probationary period may
be extended by five hundred twenty (520) hours worked, upon mutual agreement of
the Company, the Union and the employee.

Section 2.  Unless Company policies provide otherwise, probationary employees
will not be eligible for any benefits granted to regular employees under this
Agreement.  No terms of this Agreement other than this Article and the
appropriate wage rate will apply to probationary employees.

Section 3.  Employees continued in employment after the end of the probationary
period will become full-time employees and will be credited with continuous
service from the original date of hire.

                                  ARTICLE 10
                                 JOB POSTINGS

Section 1.  Whenever the Company determines a vacancy, other than a temporary
vacancy, exists in any biddable job classification, or a new job becomes
available, the Company will post a job posting on the bulletin boards for ten
(10) consecutive days.  Employees desiring to bid on the vacancy will apply in
writing to the Human Resources Department within the allotted ten (10) days.
Laid off employees, who have seniority rights, will be eligible to bid on all
job postings. Upon request, a copy of the job posting and of all bids will be
provided to the Local Union President.

Section 2.  The Company will determine the successful candidate based on
demonstrated performance and skill consistent with the Evaluations Article. When
there are two or more employees of equal skill and performance, the principle of
plant seniority will govern. If no qualified candidate applies or no bid is
received, the job may be filled by the Company from any other source.

Section 3.  Temporary vacancies of less than ninety (90) days may be filled at
the Company's discretion.

Section 4.  If the successful bidder proves unsatisfactory after a thirty (30)
day evaluation period, or chooses not to continue in the new position within the
thirty (30) day evaluation period, the employee will be returned to the position
last held with no loss of seniority.  The Company will then fill the position
with the next most qualified candidate from the original posting.

Section 5.  An employee who is awarded a job posting outside his department
cannot bid for another job for a period of one (1) year.  An employee who is
awarded a job posting within his department cannot bid for another job for a
period of four (4) months.
<PAGE>

                                  ARTICLE 11
                              LAY-OFF AND RECALL

Section 1.  In instances of layoff, recall, or job elimination, the Company,
consistent with the Evaluations Article, will consider employees' demonstrated
performance and skill.  When there are two or more employees of equal
performance and skill, the principle of plant seniority will govern.  Temporary
employees and probationary employees will be laid off prior to employees on the
seniority list, unless the temporary or probationary employees have special
skills not held by regular employees.

Section 2.  An employee has ten (10) days to respond to a recall to work by
certified mail.  The ten (10) days will begin running when the Company makes its
initial attempt to recall.  Unless other arrangements are made, the recalled
employee will have up to fourteen (14) days to return to work after responding
to the Company's offer.  Failure to respond or return to work within the time
limits outlined in this Section will result in a loss of seniority.


Section 3.  The Company will meet with the MUC Committee to discuss any layoffs
or reduction-in-force prior to implementation.  The Company will notify the
Union of any pending layoff or reduction-in-force as far in advance as possible.
If a layoff is less than ninety (90) days in duration, the Company will pay its
portion of the cost of fringe benefits during the layoff.

                                 SEVERANCE PAY

Section 1.  Any full-time employee who loses seniority because of a long-term

at the employee's base rate of pay for each full year of continuous service with
the Company up to a maximum of fifteen (15) weeks of pay.

                                  EVALUATIONS

Section 1.  The job performance of all bargaining unit employees will be
evaluated on an annual basis.  New employees will be evaluated at the conclusion
of their probationary period.  This evaluation will be utilized until the next
annual review occurs.  These evaluations will have two components.  The first
will be based on performance.  The second will be a skills assessment.  The
Company retains the right, with input from the review committee, to
<PAGE>

periodically modify the evaluation process. Changes in the evaluation process
will be announced at least six (6) months before the end of the evaluation
period.

Section 2.  The performance evaluation results will be standardized between
departments (each of which must be ten (10) or more employees).  In other words,
each employee's performance score in the department will be ranked in raw score
order and assigned a percentile rank within the department.  This percentile
rank will be the number that will be used when comparing the performance of
employees from different departments.  Employees who are within ten (10)
percentage points of each other will be considered substantially equal for
performance purposes.

Section 3.  The skills assessment will be standardized in the same manner as
the performance evaluations.  Employees who are within ten (10) percentage
points of each other will be considered substantially equal for skills purposes.

Section 4.  Job restructuring, assignments, layoffs, eliminations, recall, and
other changes materially affecting employment will initially be based on the
employee's performance and skill level demonstrated in the employee's last
evaluation.  In each instance where performance and skill are a factor in the
Company's decision, the Company will articulate a minimum skill level needed for
consideration.  Employees who have the requisite skill level will initially be
compared on the basis of their job performance.  If their performance is
substantially equal, their skill levels will be compared.  If the skill level is
also substantially equal, plant seniority will be the deciding factor.  If, at
any step of this comparison process, the employees are not substantially equal,
the employee with the superior performance or skill level will be given
preference.

Section 5.  When the evaluation process is completed for an entire department,
employees will be provided with a copy of their individual performance
evaluation and skills assessment.  Employees who have questions about their
evaluations should initially discuss them with the individual who completed the
evaluation.  If this discussion does not resolve the matter, a request to meet
with the review committee may be filed.  This request must be made within
fifteen (15) days of receipt of the evaluation and specifically state with what
parts of the performance evaluation or skills assessment the employee disagrees.
The review committee is the only avenue available to challenge performance
evaluations and skill assessments, as they are not subject to the grievance and
arbitration procedures of this Agreement.

Section 6.  The review committee will meet with the employee and other involved
parties to determine whether either the performance evaluation or skills
assessment should be revised.  The decision to revise the evaluation or skills
assessment must be agreed upon by a majority of the review committee
<PAGE>

members hearing the matter. The decision of the review committee will be final
and binding on both the Company and the employee.

Section 7.  The Company and the Union will each designate five (5) individuals
who may act as review committee members.  When an employee requests to meet with
the committee, each party will select two (2) members from their respective
groups, who are not within the employee's department, to review the performance
evaluation and skills assessment.  At the review committee's request, the Vice
President of Operations will sit as a fifth member of the committee.

Section 2.  Changes in working schedules (other than temporary incidental
changes) will be discussed with the MUC prior to implementation.

Section 3.  An employee who is called back for immediate work after leaving
Company property or who is called for immediate work outside their scheduled
working hours, and actually begins working, will be paid time and one-half (1
1/2) for work actually performed or a minimum of four (4) hours at the straight-
time rate, whichever is greater.  Employees will be compensated for call out
travel at the current Company mileage rate, up to a maximum of fifty (50) miles
each way.

Section 4.  If an employee's regularly scheduled shift is canceled less than
ninety (90) minutes before it is scheduled to begin, the employee will either
work a minimum of four (4) hours or be paid four (4) hours at his regular hourly
rate in lieu of work.

Section 5.  Upon prior approval of the supervisors involved, employees may
mutually agree to exchange shifts or days off provided the exchange does not
cause any disruption or increased cost to the Company, and that the exchange
does not cause the employee to be on duty more than sixteen (16) hours in any
twenty-four (24) hour period.

Section 6.  The Company agrees that overtime will be distributed as uniformly
and equally as possible and practical within each classification.  Employees
will not be forced to work overtime as long as there are employees in their
classification who are qualified and willing to work such overtime.  If no
qualified employees volunteer to accept requested overtime, the Company will
assign
<PAGE>

the overtime to a qualified employee, based on reverse order of department
seniority. Employees who decline offered overtime will be charged for the
overtime offered as if it has been worked for the purpose of overtime
allocation.

Section 7.  Any employee who has worked sixteen (16) consecutive hours will be
compensated at double (2) time for all hours worked over sixteen (16).  Any
employee who has worked sixteen (16) or more hours will be allowed a rest period
of at least eight (8) hours with no loss of overtime pay.

Section 8.  Pyramiding of overtime is prohibited.

Section 9.  For the purpose of computing weekly overtime the following will be
considered as time worked: holidays, jury/witness service, union business
involving contract administration or negotiations for the purpose of renewing
this Agreement, which fall on an employee's regularly scheduled work day; or
meetings, training and conferences required by the Company.  These hours will
not exceed the number of hours in the employee's normal work day.

Section 10. Except for the first shift worked for each work rotation, an
employee will be given twenty-four (24) hours notice of a change in shift.

Section 11. Employees who work a shift beginning after 12:00 (noon) will be
paid a shift differential of fifty cents ($.50) per hour.

                           CLASSIFICATION AND WAGES

Section 1.  The classifications and rates of pay are attached to this Agreement
and will continue in effect for the duration of this Agreement.

Section 2.  Employees temporarily assigned to work in a classification other
than their current classification will continue to be paid the rate of pay for
their current classification.

Section 3.  Management personnel may perform bargaining unit work when training,
investigating, testing, and in emergencies, or situations in which no qualified
bargaining unit employee is available to do the job required.

Section 4.  If a full-time employee is demoted, through no fault of their own,
from their regular classification, the employee will receive the higher rate of
pay for a period one (1) week for each full year of service at the previous
classification, at the time assigned to the lower classification.  There will be
no pyramiding of rate retention under this Article.

                               SAFETY AND HEALTH

Section 1.  The Company and the Union believe an effective safety and health
program is essential for employee morale and well-being, as well as the long-
term viability of the Company.  Accordingly, the Company recognizes its
obligation to prevent, correct and eliminate all unhealthy and unsafe working
conditions and practices.  Employees are also expected to recognize, address and
report unhealthy or unsafe working conditions.  Further, employees will follow
all Company safety and health rules and procedures and comply with applicable
State and Federal regulations.

Section 2.  The Company will recognize one (1) Safety and Health Committee for
the Nye facilities and one (1) Safety and Health Committee for the Columbus
facilities.  The respective Safety and Health Committees will consist of
representatives elected annually by members of each work group at each location.
These Committees will meet monthly to discuss safety and health issues,
recommend corrective actions, and communicate safety and health information back
to employees.

Section 3.  There will be a Joint Safety and Health Review Committee ("JSHRC")
at each location where a Safety and Health Committee exists.  It will be
composed of four (4) members of the Safety and Health Committee and will meet at
least quarterly.  There will be equal representation of Company appointees and
Union appointees on the JSHRC.  Time spent in JSHRC meetings and approved
activities will be considered as time worked.  All matters considered and
handled by the JSHRC will be reduced to writing, and the joint minutes will be
maintained and communicated at the monthly Safety and Health Committee meetings.

Section 4.  The Company will conduct occupational health and medical monitoring
to measure exposures in the workplace as appropriate, or upon the recommendation
of the JSHRC.  Results will be distributed to the appropriate Safety and Health
Committees and the Local Union President, to the extent that employee
confidentiality is not compromised.

Section 5.  The Company will pay for required medical examinations and the
results will be kept in the employee's confidential medical file.  Upon request,
a copy of these records will be provided to the affected employee.

Section 6.  Personal protective equipment required by statute or for special

allow employees to purchase subsequent or additional personal protective
equipment through the warehouse at Company cost. Employees whose personal
protective equipment is damaged or destroyed through abnormal conditions, not

through the warehouse at Company expense.

Section 7.  Prescription safety glasses will be provided at a rate of one (1)
pair per year.  Replacement non-prescription safety glasses will be available.

be considered as time worked.  The cost of Company approved training will be
paid by the Company and expenses reimbursed based on current Company policy.

Section 9.  No employee will perform unsafe work or be required to perform
unsafe work.  Employees performing unsafe work or unsafe practices will be
subject to disciplinary action, up to and including discharge.  Refusal to
perform unsafe work will not warrant or justify any present or future
disciplinary action.

receive pay at the rate of time and one-half (1  1/2) plus holiday pay for all
hours worked.  Each full-time employee not required to work on these holidays
will receive eight (8) hours pay for such holidays at their regular rate of pay.
Employees scheduled to work on a holiday who fail to report to work will not
receive holiday pay.

Section 3.  When a Saturday or Sunday holiday is observed on a weekday, the
holiday pay will apply on that weekday.  Employees scheduled to work seven (7)
days per week rotating shift, will be paid holiday pay on the calendar day on
which the holiday occurs.  The actual holiday schedule will be posted each year,
as soon as practical.

Section 4.  An employee absent on either the scheduled workday before or after
the holiday will not receive pay if the absence is not approved by the Company.
An employee who is receiving disability benefits on both the scheduled workday
before and after the holiday will not receive pay for the holiday.

Section 5.  Employees will be entitled to one (1) personal holiday which may be
taken after the employee has completed their probationary period, provided at
least one (1) week's notice is given to the Company.  Scheduled annual vacation
will take precedence over the scheduling of personal holidays.

     In the case where more than one employee per crew requests to take a
personal holiday on the same day, department seniority will govern if the
personal holiday had been scheduled between January 1 and March 31 of any year.
Personal holidays will be allocated on a first come, first serve basis if
scheduled after April 1 of any year. Personal holidays will be allocated and
granted based on operational needs and the wishes of the employee. No more than
one (1) person per crew will be allowed off on personal holiday on any
particular day, except at Company discretion.

immediately after a holiday, the employee will be paid according to this
Article, provided that the employee works the last scheduled shift prior to and
the next scheduled shift after the holiday and the personal holiday.

     If the personal holiday is not scheduled to be taken in the calendar year,
the employee will be paid for eight (8) hours for the personal holiday at their
base rate.  Personal holidays may not be banked or carried over into the next
year.

   10 or more                            160 hours

Section 2.  At the beginning of the calendar year, each full-time employee who
has completed one year of continuous service will be credited with vacation
based on length of service.  Employees who have less than one year of service,
but have completed their probationary period, will be credited with a pro rata
amount of vacation on January 1.  Employees must use a minimum of eighty (80)
hours of their vacation leave annually.

Section 3.  At the beginning of each calendar year, full-time employees who have
completed fourteen (14) or more years of continuous service will receive a one
thousand dollar ($1,000) bonus.

Section 4.  Employees may choose to receive pay in lieu of time off for vacation
in excess of eighty (80) hours.  Pay in lieu of time off will also be provided
when the Company requests an employee to forego his vacation.  If, due to an
extreme situation, the Company requires an employee to work during a previously
scheduled vacation, the Company will make the employee whole for any verifiable,
non-refundable expenses incurred by the employee.  Vacation cannot be carried
over into the next calendar year without the Company's approval.  Vacation must
be taken in full-shift increments, unless shift scheduling dictates otherwise.

Section 5.  Vacation schedules will be posted or circulated among employees
during the first two (2) weeks of January of each year for employees to indicate
their vacation preference.  Vacation request forms will be utilized, with a copy
of the approved form returned to the employee.  Vacation will be scheduled to
meet the preference of employees whenever possible.  In case of conflict over
any vacation period, vacation will be granted in order of department seniority.
Where an employee elects to split vacation, that employee's seniority rights
will prevail only for the first choice until all other employees in the vacation
unit have had their first choice.  It is understood that the Company retains the
right to schedule vacations as operational conditions dictate.  However, no
employee will be forced to take vacation which has already been approved at a
time undesirable to the employee. Vacation requests must be pre-authorized by
the supervisor at least one (1) week in advance.

Section 6.  Holidays falling during an employee's vacation will be
<PAGE>

compensated for by holiday pay or by a one-day extension of the vacation, as the

must be made by the Union to the Company not less than fourteen (14) days before
the leave.

Section 2.  Upon thirty (30) days written notice from the Union, a long-term
unpaid leave of absence to perform work for the Union will be granted for one
(1) employee for up to one (1) year.  The employee may elect to return to the
employee's previous classification with a thirty (30) day written notice for
reinstatement from the Union to the Company.  The employee will hold and
accumulate seniority and continuous service for all purposes during the leave.
Upon request, the employee will be allowed to continue in the Company Group
Health Plan, and any Disability Plans, by paying the full cost of the benefits
during the leave.  Reinstatement will be granted if the employee is physically
able to return to the previously held classification, as determined by a Company
paid physical examination.  If the employee is physically unable to return to
the previously held classification, the employee will be allowed to return to a
job the employee is qualified to perform, if such job exists.
