PART III
NARRATIVE

State below in reasonable detail the reasons why Form 10-K, 11-K, 20-F,
10-Q, N-SAR or the transition report portion thereof could not be filed within
the prescribed time period.

The Company has experienced unexpected delays in finalizing its
accounts as of December 31, 2001, and in preparing its financial
statements for the year then ended due to delays associated with
efforts to quantify the effect of unforeseen recent adverse
developments in workers' compensation claims affecting the Company's
estimates, as of December 31, 2001, for workers' compensation expense.
As a result, the Company is not able to file its Annual Report on Form
10-K in a timely manner without unreasonable effort or expense. The
Company expects to file its Annual Report no later than April 15,
2002.

PART IV
OTHER INFORMATION

(1) Name and telephone number of person to contact in regard to this
notification:

Michael D. Mulholland (503) 220-0988
(Name) (Area Code) (Telephone Number)

(2) Have all other periodic reports required under Section 13 or 15(d) of
the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act
of 1940 during the preceding 12 months or for such shorter period that the
registrant was required to file such report(s) been filed? If the answer is no,
identify report(s). -X- Yes --- No

(3) Is it anticipated that any significant change in results of operations
from the corresponding period for the last fiscal year will be reflected by the
earnings statements to be included in the subject report or portion thereof?
- -X- Yes --- No

If so, attach an explanation of the anticipated change, both narratively
and quantitatively, and, if appropriate, state the reasons why a reasonable
estimate of the results cannot be made.

The Company believes that its 2001 operating results will reflect a
significant decline from its operating results for 2000 due to the
Company's re-evaluation of its December 31, 2001, estimate of workers'
compensation expense. The Company and its outside actuary are
evaluating the full potential financial effect of these developments,
but the Company is not able to make an estimate of appropriate
adjustment to the accrual for workers' compensation expense until it
has completed discussions with its actuary, independent accountants,
and other advisers and afforded its audit committee and independent
accountants an opportunity to review the final determination.
