In regards to your questions, I contacted Tim Clark at Unisource here in
Minneapolis and he gave me the following answers to the questions posed in
your email.

First: On the average, a 40-inch diameter roll of paper 17.5 inches wide
weighs 640lbs whether it is 50-lb, 60-lb or 70lb basis weight paper that has
a smooth finish and is uncoated.

Second: With this type of paper, a 50-lb basis weight roll contains 27,000
lineal feet of paper, 25,000 lineal feet if it is a vellum paper. A 60-lb
basis weight roll of paper contains 23,000 lineal feet of paper, 19,200
lineal feet if it is a vellum paper. A 70-lb basis weight roll of paper
contains 19,800 lineal feet of paper, 17,900 lineal feet if it is a vellum
paper.

Third: 50-lb basis weight paper (17.5 x 22 3/4 inches) weighs 40.5 lbs per
1000 cutoffs (17 x 22 inch pages). 60-lb basis weight paper of this size
weighs 48.6 lbs per 1000 cutoffs. 70-lb basis weight paper of this size
weighs 56.7 lbs per 1000 cutoffs.

Therefore, in a PERFECT WORLD, a 40-inch roll of 50-lb paper would yeild
15,800 sheets (pages). A 40-inch roll of 60-lb paper would yeild 13,160
sheets and a 40-inch roll of 70-lb paper would yeild 11,290 sheets. These
numbers must be tempered with the uncertainty associated with waste and
spoilage and the variance in paper roll diameter.

As to the question regarding the difference in price between 100%
post-consumer and 40% post-consumer, Tim could not answer the question
because it was not specific enough as to what kind of paper they are looking
for in addition to the post-consumer fiber content.

Tim Clark's phone number at Unisource is (612) 228-1234.
