Notes to Quarterly Financial Statements Boise Cascade Office Products
=====================================================================
Corporation
===========

Organization and Basis of Presentation.  Boise Cascade Office Products
Corporation (together with its subsidiaries, the "Company" or "we")
headquartered in Itasca, Illinois, is one of the world's premier business-to-
business distributors of products for the office with operations in Australia,
Belgium, Canada, France, Spain, the United Kingdom, and the United States.  At
December 31, 1999, Boise Cascade Corporation owned approximately 81% of our
outstanding common stock.  These financial statements are unaudited statements
which do not include all Notes to Financial Statements and should be read in
conjunction with our 2000 Form 10-K. The 2000 Form 10K will be available in
March 2000.

Other Operating (Income) Expense.  During the second quarter of 1999, we revised
the amount of a restructuring reserve that we established in the fourth quarter
of 1998 for our U.K. operations.  The restructuring program was less costly than
originally anticipated.  As a result, we recorded an increase to operating
income of approximately $4.0 million ($2.7 million, net of tax benefit or $.04
per share - diluted) in the second quarter of 1999. The increase to income
included a favorable adjustment to "Cost of sales" in the Statements of Income
of about $0.8 million, which resulted from a lower than expected inventory
write-down.  The remaining $3.2 million of income is included in "Other
operating income" in the Statements of Income.

Earnings Per Share.  Unaudited basic earnings per share for the three months and
year ended December 31, 1999 and 1998, were computed by dividing net income by
the weighted average number of shares of common stock outstanding during the
periods.  Unaudited diluted earnings per share for the three months and year
ended December 31, 1999 and 1998, include the weighted average impact of stock
options assumed exercised using the treasury method.

Acquisitions.  In January 1999, we acquired the office supply business of
Wallace Computer Services.  In September 1999, we acquired the office supply
business of Supply West. The annual sales of these acquisitions were
approximately $50 million at the time of announcement.  The results of
operations of acquired businesses are included in our operations subsequent to
the dates of acquisition.

Income Taxes.  The tax provision rate for the twelve months ended December 31,
1999, was 42.7%, compared with a tax provision rate of 44.75% for the same
period in the prior year.
