Item 1.01 Entry into Material Agreement.

On December 3, 2010, the registrant was administratively dissolved by the Oregon Secretary of State for failure to maintain its corporate registration. The Board of Directors determined not to correct the involuntary dissolution, because the registrant does not have sufficient funds to cover the costs of a special meeting of shareholders to approve a voluntary dissolution. On December 7, 2010, the registrant adopted a Plan of Liquidation and a Liquidating Trust Agreement, effective as of December 7, 2010~~, copies of which are attached to this report as Exhibits 10~~.1 ~~and 10.2.~~ Pursuant to the Plan of Liquidation, the Company will complete a full liquidation effective December 28, 2010 (the “Liquidation Date”), at which date all remaining assets of registrant, consisting of approximately $37,500, will be transferred to the Columbia Bancorp Liquidating Trust (the “Trust”). ~~While~~On December 22, 2010, the ~~beneficiaries~~registrant and the Trust entered into an Assignment and Assumption Agreement, a copy of which is attached as Exhibit 10.1 to this report. The Assignment and Assumption Agreement clarifies that, in accordance with the Plan of Liquidation and Liquidating Trust ~~will~~Agreement, the shares of capital stock of registrant will be cancelled as of the Liquidation Date and converted into beneficial interests in the Trust, with the shareholders of registrant, ~~with~~of record as of the Liquidation Date having beneficial interests in the Trust ~~being~~ in proportion to their respective ownership interests in registrant as of the Liquidation Date. On and as of the Liquidation Date, the Trust will assume the liabilities of the registrant and the Trust assets will first be used to pay all outstanding expenses, obligations and other liabilities of the registrant outstanding on the Liquidation Date whether then known or not. Only the remaining assets, if any, after payment of such liabilities would be available for distribution. Such expenses, obligations and liabilities are expected to include, without limitation, expenses of liquidation and any distributions of assets, final tax returns professional fees, claims by known claimants, claims by officers and directors for indemnification under the provisions of the registrant’s articles of incorporation, bylaws, pursuant to contract and Oregon law, and other claims against the registrant not yet known to the Board of Directors,.

The Board of Directors expects that the assets remaining after satisfaction of all such expenses, obligations and liabilities will be insufficient to distribute any funds to shareholders of registrant. Accordingly, shareholders should not expect to receive any liquidating distributions with respect to their shares under the Plan of Liquidation, nor any distributions from the Trust.
