EXHIBIT 4.1

Sixth Supplemental Indenture

                THIS SIXTH SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”) is made as of October 29, 2004, between Boise Cascade Corporation, a Delaware corporation (the “Company”), and U.S. Bank Trust National Association (as successor in interest to Morgan Guaranty Trust Company of New York), as trustee (the “Trustee”). Any term used but not defined herein shall have the corresponding meaning given to it in the Indenture (as defined below).

Recitals of the Company

                The Company and the Trustee have heretofore executed and delivered an Indenture dated as of October 1, 1985, as amended or supplemented (the “Indenture”), pursuant to which the Company has heretofore issued its 6.50% Senior Notes due 2010, in the aggregate principal amount of $300,000,000 and 7.00% Senior Notes due 2013, in the aggregate principal amount of $200,000,000 (collectively, the “Senior Notes” and each a “series” of Senior Notes). The Company desires to amend or eliminate certain provisions of the Indenture as hereinafter set forth.

                Pursuant to its Offer to Purchase and Consent Solicitation, dated October 5, 2004 (the “Offer to Purchase”), the Company commenced a tender offer (as amended from time to time, the “Tender Offer”) for aggregate consideration up to $800,000,000 for its outstanding Senior Notes and for certain amounts of other Company securities and a solicitation of consents (as amended from time to time, the “Solicitation”) from the holders of the Senior Notes to certain amendments to the Indenture (the “Proposed Amendments”).

                Section 902 of the Indenture provides, with certain exceptions, that the Company and the Trustee may amend or supplement the Indenture with the consent of the holders of not less than 66²/₃% in aggregate principal amount of each series of Senior Notes then outstanding.

                The Company has determined that, with the consent of the holders of at least 66²/₃% in aggregate principal amount of each series of Senior Notes outstanding, the amendments set forth in Article I hereof are authorized or permitted by Section 902 of the Indenture. In furtherance thereof, the Company has delivered to the Trustee an Opinion of Counsel to that effect and an Opinion of Counsel and an Officers’ Certificate pursuant to Section 102 of the Indenture to the effect that all conditions precedent provided for in the Indenture to the Trustee’s execution and delivery of this Sixth Supplemental Indenture have been complied with.

                Pursuant to the Tender Offer and Solicitation, the holders of at least 66²/₃% in aggregate principal amount of the 6.50% Senior Notes due 2010 (the “6.50% Senior Notes”) then outstanding have duly consented to the Proposed Amendments, as such Proposed Amendments are described in the Offer to Purchase.

                All acts and things necessary to amend the Indenture and to make this Sixth Supplemental Indenture a valid agreement of the Company and the Trustee, in accordance with its terms, have been done.

                NOW, THEREFORE, the Company hereby covenants and agrees with the Trustee as follows:
