remain static over the 3 year period. One supervisor will be used at an annual salary of $38,000. Salary

material costs will be at a rate of $0.20 per square metre occupied. Fixed costs of $7,200 per year will also
be charged to Pender by the contractor.

A rate of $1.40 per square metre occupied will be charged. In addition a part time supervisor will be
required at an annual cost of $24,000 plus benefits at 15%. Fixed costs of $4,600 per year will be charged to
Pender by Company B. No increases are forecast through the three year period.
