     Employees will take additional earned vacation time consecutively unless
     otherwise mutually agreed to by the employee and the Company.

absence for any reason other than industrial injury or regular S & A coverage,
he/she shall cease to accrue vacation time until he/she returns to work and when
he/she does, the vacation he/she would otherwise have been entitled to for that
year shall be reduced in proportion to the number of days of excused absence in
excess of thirty days. Employees who have less than two (2) weeks vacation
eligibility may, at the convenience of the Company, be requested to work for the
balance of the shutdown when work is available.

When an Employee is asked to work his/her vacation weeks, it shall then be the
Employee's and the Company's mutual decision as to when he/she will take his/her
vacation. In the absence of a mutual agreement, the Employee shall not be
required to work.

VACATION ELIGIBILITY IN EXCESS OF 10 DAYS MAY BE TAKEN ONE DAY AT A TIME. (CAN
BE USED IN LIEU OF SICK DAYS IF EMPLOYEE DESIRES).

day(s) as Vacation.

If an Employee dies without receiving his/her vacation or compensation in lieu
thereof, the amount shall immediately be paid to his/her beneficiary or estate
upon proper proof.

(h)  The eligible accrued, unused vacation balance will be paid out to any
     employee who has been laid off, discharged or resigned

conditions:

     paid to Chart Storage Systems, by the first of each month.

     Failure to make such monthly payment in a given month removes the former

military duty, industrial accident, funerals covered in the Bereavement Clause,
leave of absence (personal, medical or sickness and accident) or illness
absences of two (2) or more consecutive days verifiable to the Personnel

chargeable absences.

In each month, lost time due to leaving the plant early shall be additive and
for each twelve (12) hours of such lost time the Employee shall be charged with
one (1) day's absence for that month.

Excessive Tardiness: For each tardiness occurrence in excess of five (5) in one
(1) month of rolling 12 month period, the offending Employee shall be subject to
the below disciplinary action(s) on a progressive basis:

Violations in absenteeism and tardiness as provided for hereinabove shall
subject the offending Employee to discipline as follows:

     Step 1: Verbal warning in the presence of the Shop Steward.
     Step 2: Written warning with a copy to the Steward.
     Step 3: One (1) week's suspension without pay.

the Employee involved and the Company shall be convened to lay out the
Employee's record and ways and means to correct. No disciplinary action shall be
taken at this meeting. A continued pattern by the Employee in the future of
absenteeism shall subject him/her to disciplinary action. An absence during
which an Employee is admitted as an "inpatient" to a hospital, or under a
doctor's care for a condition which he/she was previously hospitalized, shall
not be counted in the disciplinary process.

The above-mentioned provisions on absenteeism and tardiness shall become

Committee.

                                TRAINING PROGRAM

All new employees will be hired as general helpers, unless skill requirements
and actual qualifications dictate otherwise.

Within two (2) weeks after the probationary period, the foreman and employee
will discuss the employee's job classification preference. (Example: machinist,
welder, welder/fitter, radiographic technician, test technician, etc.) If a need
exists, the employee were to indicate a preference for welding, such employee
would be assigned as a general helper/welder with work assignments in this job
classification whenever possible.

All new employees in the apprentice training program will be reviewed every
three (3) months as to progress of their training. Progress will be evaluated on
the basis of specific job skills developed since the last review. The foreman
will conduct the review as to progress and deficiencies in development of job
skills using input from other trainers. Such employees will be paid increases
per review if progress is satisfactory.

An employee can advance in job classification skill level by on-the-job training
and job-related classroom instruction (example: blueprint reading, math, etc.)

There is no prescribed or minimum time for an employee to advance to a job
classification skill level. if the employee does not obtain the skills to
perform the job classification requirements within a two (2) year period after
probation, such employee will be re-classified as a general helper.

When an employee completes the training for a job classification, such employee
will be paid the rate for that classification provided a need exists for work in
that classification.

Specific criteria for evaluation of progress within a specific job
classification will be developed. Employees will be advised of the basis for
review and progression within a job classification at the start of the training
cycle.

The Company will lay off in accordance with the present agreement dated August
29, 2002, on the basis of job classification. It is the intent of the Company to
retain the most senior employee in the job classification in preference to
retaining a shorter service employee in the general helper classification.

Concerning those individuals who were part of the Bargaining unit on or before
the Contract amendment of April 11, 2001 and employed in "Semi-Skilled"
Manufacturing classifications as set forth in such amendment, the Company will
review each individuals ire to train and work in a "Skilled Manufacturing"
classification. If the individual shows interest in pursuing such training, the
Company will initiate the cross training providing there is a good probability
that these additional skills will be utilized in the foreseeable future.
