The purpose of the Acquisition was the sale of Boise Cascade’s paper, packaging and newsprint and transportation businesses as well as most of its headquarter operations.  In connection with the Acquisition, BCH received the Shares, as well as cash and a promissory note.

                                                Investor Rights Agreement.  In connection with the Acquisition, the Company, BCH and certain other stockholders of the Company entered into an investor rights agreement. The investor rights agreement provides that BCH will have the right to designate a number of directors to the Company’s board proportional to the voting power represented by the shares of the Company’s Common Stock that BCH owns until such time as BCH owns less than 5% of the voting power of all of the outstanding Common Stock of the Company. Holders of more than 5% of the Common Stock will have certain information and inspection rights. Additionally, the investor rights agreement sets forth affirmative and negative covenants to which the Company will be subject to as long as BCH owns 33% of the Common Stock issued to it as of the closing date of the Acquisition. The negative covenants restrict the Company and/or its subsidiaries from conducting certain activities or taking certain actions without the affirmative written consent of holders of the majority of the shares acquired by BCH, including, without limitation, making distributions on its equity securities, redemptions, purchases or acquisitions of its equity securities, issuances or sales of equity securities, securities exchangeable or convertible for equity securities, debt or convertible or exchangeable debt securities, loans, advances or guarantees, mergers and

acquisitions, asset sales, liquidations, recapitalizations, non-ordinary business activities, changes of organizational documents, change of arrangements with its officers, directors, employees and other related persons, incurrence of indebtedness for borrowed money or capital leases above specified thresholds and a sale of the Company.  Pursuant to the affirmative covenants, unless the holders of a majority of the shares acquired by BCH have otherwise consented in writing, the Company and each of its subsidiaries is required to perform certain activities, including, without limitation, preservation of its corporate existence and material licenses, authorizations and permits necessary to the conduct of its business, maintenance of its material properties, discharge of certain statutory liens, performance under material contracts, compliance with applicable laws and regulations, preservation of adequate insurance coverage, and maintenance of proper books of record and account.

                                                In addition, the investor rights agreement sets forth additional affirmative covenants to which the Company and its subsidiaries will be subject during any period(s) in which BCH and/or any person or entity affiliated with BCH is required to consolidate the results of operations and financial position of the Company and/or any of its subsidiaries or to account for its investment in the Company under the equity method of accounting (determined in accordance with GAAP and consistent with the Commission’s reporting requirements), including, without limitation, maintaining disclosure controls and procedures and internal control over financial reporting as defined in Exchange Act Rule 13a-15, maintaining the same fiscal year and monthly and quarterly accounting periods as BCH, delivering periodic financial statements and other financial information such that BCH can properly satisfy its reporting obligations under the Exchange Act and applicable law, allowing BCH prior review of Company filings with the Commission and cooperating fully with BCH in the preparation of any of its public reports and filings with the Commission.

                                                The investor rights agreement also provides for certain registration rights with respect to shares held by the stockholders that are party to the investor rights agreement. Holders of at least a majority of the shares acquired by BCH will have the right to demand registration under the Securities Act of all or any portion of their registrable securities subject to certain limitations. Holders of these shares may demand five long-form registrations and an unlimited number of short-form registrations. Additionally, whenever the Company proposes to register any of its securities under the Securities Act and the registration form to be used may be used for the registration of registrable securities, holders of a majority of the shares acquired by BCH may request the inclusion of its registrable securities in such registration.

Item 6.                                   Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

The description of the investor rights agreement described in Item 4 of this Schedule 13D is hereby incorporated by reference.

Contingent Value Rights Agreements.  On or about February 1, 2008, Boise Cascade entered into contingent value rights agreements (the “Agreements”) by and among certain investors (the “Investors”) in the Company, Terrapin Partners Venture Partnership (“Terrapin”) and the Company.  Under the Agreements, the Investors received from Terrapin and Boise Cascade (the “Grantors”) certain contingent value rights (“CVRs”) to receive payments in cash, shares of the Company’s common stock or a combination of cash and shares.  In exchange for the CVR, each Investor caused its shares to be voted in favor of each proposal set forth in the Company’s Definitive Proxy Statement filed with the Commission on January 23, 2008, as amended, and agreed not exercise any conversion rights in respect of such shares and to revoke any such exercise previously made.

The Grantors gave the Investors CVRs equal to the number of shares held by each Investor or the number of shares such Investor had the right to vote at the special meeting of stockholders of the Company held on February 5, 2008.  In order to receive a settlement of the CVRs, (i) the Common Stock’s Anniversary Price (defined as the arithmetical average of the volume weighted average trading price of the Common Stock as reported by Bloomberg Professional Service for the period beginning 9:30 a.m., New York City time and ending at 4:00 p.m., New York City time for the 30 trading days prior to February 5, 2009) must be less than $10.50 and (ii) the Investor must have given written notice to the Grantors requesting payment of the CVRs between February 6, 2009 and February 15, 2009.  Subject to certain adjustments set forth in the Agreements, the Grantors will pay or transfer to each Investor the amount (the “CVR Payment”) per CVR by which the Anniversary Price is less than $10.50, up to a maximum of $1.00.

 The CVR Payment, if any, will be paid by each Grantor, in its sole discretion, in cash, shares, or a combination of cash and shares.  The Grantors will be jointly and severally liable to the Investor for the CVR Payment, but as between the Grantors, each Grantor will be individually liable for 50% of the CVR Payment.  The CVRs and the obligations thereunder will automatically terminate if prior to February 5, 2009, the closing price of the shares, as reported on Bloomberg Professional Service, is $10.50 or greater for (a) any 20 days of any period of 30 consecutive trading days or (b) 10 consecutive trading days.  Boise Cascade’s maximum liability under the Agreements is expected to be approximately $10,000,000 ($20,000,000 if Terrapin fails to meet its obligations).

A form of the contingent value rights Agreement is attached hereto as Exhibit C.
