     WHEREAS, the parties intend that the transactions contemplated hereby will permit the expansion of the Company’s business, the enhancement of the capital base on which the Company can conduct business, and an appropriate allocation among the parties of the anticipated gains from such expansion of the business and the risks associated with such expansion efforts; and

     WHEREAS, the parties agree that a portion of the payment to Simonich for the Purchased Shares shall be determined based on future performance of the Company (the “Earn-Out Payments”), to be determined and to be paid in accordance with the provisions set forth herein; and

     WHEREAS BOCH has agreed to acquire the Purchased Shares, and to place $800,000 in a restricted cash account of the Company on the terms, and subject to the conditions, set forth herein;

     NOW, THEREFORE, in consideration of the foregoing premises and the mutual covenants and conditions set forth in this Agreement, the parties agree as follows:

     In addition to its performance of its other obligations under this Agreement, BOCH shall make the following payments to Simonich as consideration for the Purchased Shares:

     a. $1,500,000 in cash, payable at the Closing (the “Closing Payment”); and

     b. the Earn-Out Payments, payable pursuant to the terms of the Earn-Out Agreement (the “Earn-Out Agreement”) which is attached as Exhibit 1.2(b) hereto and which is hereby incorporated by reference.

At the Closing, Simonich and the Company have the obligation to deliver to

BOCH stock certificates representing the Purchased Shares. BOCH shall provide the Closing Payment to Simonich as of the Closing by certified or bank check(s) or by wire transfer(s) of immediately available funds to an account designated by Simonich.

          1.4 Additional Agreements and Conditions.

     (a) For so long as BOCH owns the Purchased Shares, Company shall declare and pay dividends to BOCH equal to 51% of the annual after-tax profits of Company. The dividends shall be payable with respect to each calendar quarter as follows: For each calendar quarter of the year, Company shall calculate the after-tax profit for such quarter, and shall pay 90% of the dividends payable to BOCH so calculated to BOCH within 45 days of the end of such quarter. With respect to the fourth quarter, Company shall also pay to BOCH any difference between the amount paid in prior quarters and the full amount of the required dividend; provided, however, that the aggregate amount paid in the prior three quarters, plus any payment respecting the fourth quarter, shall not exceed the dividend amount calculated for the entire year.

     (b) Company shall be managed by Simonich, who shall serve as President, subject to supervision by the Company’s Board of Directors. In consideration of the transactions contemplated hereby, Simonich shall enter into the Executive Employment Agreement (“Executive Employment Agreement”) with the Company in the form attached hereto as Exhibit 1.4(b), which is incorporated herein by reference.

     (c) The Board of Directors shall consist of seven (7) directors, one of whom shall be Simonich, three (3) of whom shall be nominated by BOCH in its sole discretion, and three (3) of whom shall be nominated by Simonich in his sole discretion. In addition, the Board shall create a Compensation Committee consisting of three (3) directors, of whom two (2) shall be the BOCH director designees. The voting agreement provisions of Section 6.5 are intended to effectuate this agreement. Unless approved by the Compensation Committee as so constituted, the Board of Directors will not materially change the compensation payable (in the form of salary, bonus, perquisites, benefits, or otherwise) to Simonich or other key executives, nor shall the Board of Directors adopt an annual budget that would cause the Company’s expenses, as a percentage of projected revenues and income, to vary materially from the Company’s historic expense rates.

     (d) At the Closing, the Company shall repay existing debt of Company to Redding Bank of Commerce (the “existing debt”), consisting of the principal amount of $1,000,000 and any interest or other charges thereon.

     (e) At the Closing, BOCH shall make a contribution to capital of $800,000 to the Company (the “Capital Contribution”). The cash representing the Capital Contribution shall be placed into a restricted account at Redding Bank of Commerce and Company shall not have the right to withdraw or encumber the restricted account without the express written permission of BOCH. Interest on the restricted account shall accrue to the Company. The value of the Capital Contribution shall be excluded from the book value of the Company for purposes of Section 6 herein, and upon any dissolution of the Company or purchase of the Purchased Shares by Simonich, the Capital Contribution shall be returned to BOCH prior to the Company making any other distributions.

     (f) Following the Closing, BOCH shall be entitled to acquire, at its own expense, a Key Man life insurance policy on Simonich.

     (g) At the Closing, the Company shall enter into additional employment agreements with key executives of the Company as identified by Simonich to BOCH. Such employment agreements shall not provide such additional executives with benefits superior to those contained in the Executive Employment Agreement.

     (h) Simonich shall indemnify the Company and BOCH, as applicable, for any losses arising from any independent contractor agreements or loan loss buyback agreements existing prior to the date of the Closing or those lease agreements specified on Schedule 1.4(h), and such indemnity shall be a separate remedy from any other remedy set forth herein. Payments made by Simonich to indemnify either the Company or BOCH shall be made first from any dividends otherwise payable to Simonich, and then by offset against any Earn-Out Payments otherwise payable to Simonich, and from no other sources.

     2. Representations, Warranties and Agreements of Simonich and the Company.
