2.1.3 As of the Effective Time, each share of Umpqua capital stock outstanding immediately prior to the Holding Company Merger shall remain outstanding and shall be deemed to be one share of the capital stock of the surviving corporation.

2.1.4 All shares of NBB Common Stock that are “dissenting shares” within the meaning of CGCL § 1300 (“Dissenters’ Shares”) shall not be converted into or represent a right to receive Umpqua Common Stock or Umpqua Common Stock and Cash Consideration unless and until such shares have lost their status as dissenting shares under CGCL § 1300, at which time such shares shall be converted into Umpqua Common Stock or Umpqua Common Stock and Cash Consideration pursuant to Section 2.1.5.

2.1.5 As of the Effective Time, each outstanding share of NBB Common Stock (other than Dissenters’ Shares) shall be converted into the right to receive: (i) the number of shares of Umpqua Common Stock equal to the Exchange Ratio, (ii) cash in lieu of any resulting fractional shares, (iii) any dividend or distribution pursuant to Section 2.3.3, and (iv) in the event Umpqua elects the Cash Fill Option, an amount in cash equal to the Cash Consideration.

Upon surrender for cancellation to the Exchange Agent of one or more Old Certificates, accompanied by a duly executed letter of transmittal in proper form, the Exchange Agent shall deliver to each holder of such surrendered Old Certificates new certificates representing the appropriate number of shares of Umpqua Common Stock (“New Certificates”), together with checks for payment of cash in lieu of fractional shares to be issued in respect

2.3.3 Until Old Certificates have been surrendered and exchanged for New Certificates as herein provided, each outstanding Old Certificate shall be deemed, for all corporate purposes of Umpqua, to represent the number of shares of Umpqua Common Stock into which the shares of NBB Common Stock were exchanged pursuant to Section 2.1.5. All shares of Umpqua Common Stock to be issued pursuant to the Holding Company Merger shall be deemed issued and outstanding as of the Effective Time and whenever a dividend or other distribution is declared by Umpqua in respect of the Umpqua Common Stock, the record date for which is at or after the Effective Time, that declaration shall include dividends or other distributions in respect of all shares issuable pursuant to this Agreement. No dividends or other distributions that are declared on Umpqua Common Stock into which shares of NBB Common Stock have been converted after the Effective Date will be paid to persons otherwise entitled to receive the same until the Old Certificates have been surrendered in exchange for New Certificates in the manner herein provided. In no event shall the persons entitled to receive such dividends or other distributions be entitled to receive interest on such dividends or other distributions. In the event of a transfer of ownership of shares of NBB Common Stock that is not registered in the transfer records of NBB, a New Certificate, together with a check for any cash to be paid upon due surrender of the Old Certificate and any other dividends or distributions in respect thereof, may be issued and/or paid to such a transferee if the Old Certificate formerly representing such shares is presented to the Exchange Agent, accompanied by all documents required by Umpqua and the Exchange Agent to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid or are not applicable.

2.3.4 Any Umpqua Common Stock or cash delivered to the Exchange Agent (together with any interest or dividends thereon) and not issued pursuant to this Section 2.3 at the end of twelve months from the Effective Date shall be returned to Umpqua, in which event the persons entitled thereto shall look only to Umpqua for payment thereof.

2.3.5 Notwithstanding anything to the contrary set forth in this Agreement, if any holder of NBB Common Stock shall be unable to surrender his or her Old Certificates because such certificates have been lost or destroyed, such holder may deliver in lieu thereof a lost stock certificate affidavit and, unless waived, at the sole option of Umpqua or the Exchange Agent, an indemnity bond in customary amount together with a surety, each in a form and substance reasonably satisfactory to Umpqua or the Exchange Agent.

be entitled to receive only the payment provided for by Section 1300 of the CGCL with respect to such Dissenters’ Shares.

2.5 Anti-Dilution Provision. If Umpqua changes or proposes to change the number of shares of Umpqua Common Stock issued and outstanding prior to the Effective Date as a result of a stock split, stock dividend or similar transaction with respect to the outstanding Umpqua Common Stock, or exchanges Umpqua Common Stock for a different number or kind of shares or securities or is involved in any transaction resulting in any of the foregoing, and the record date therefor shall be prior to the Effective Date, the Exchange Ratio shall be proportionately adjusted.

11.1 Procedure for Termination. This Agreement may be terminated before the Effective Date:

(a) By the mutual consent of the Boards of Directors of Umpqua and NBB acknowledged in writing;

(b) By Xxxxxx xx XXX acting through their Boards of Directors upon written notice to the other party, if at the time of such notice the Mergers shall not have become effective by October 1, 2007 (or such later date as shall have been agreed to in writing by Umpqua and NBB acting through their respective Boards of Directors) except to the extent that the failure of the Mergers then to be consummated arises out of or results from the knowing action or inaction of such party, which action or inaction is in violation of its obligations under this Agreement;

(c) By Umpqua, acting through its Board of Directors upon written notice to NBB, if there has been a breach by NBB in its representations, warranties or covenants set forth herein such that Section 8.8 or 8.9 would not be satisfied and which misrepresentation, breach or failure is not cured within thirty (30) days notice to NBB of such misrepresentation, breach or failure; or by NBB, acting through its Board of Directors upon written notice to Umpqua, if there has been a breach by Umpqua in its representations, warranties or covenants set forth herein such that Section 9.7 or 9.8 would not be satisfied and which misrepresentation, breach or failure is not cured within thirty (30) days notice to Umpqua of such misrepresentation, breach or failure;

(d) By NBB, if its Board of Director determines in good faith (after consultation with Xxxxx Xxxxxxx LLP) that such action is required in order for the directors to comply with their respective fiduciary duties under applicable law; or

(e) By NBB, if (1) the Umpqua Measuring Price is less than $26.42, (2) NBB delivers written notice to Umpqua of its intention to terminate this Agreement within two business days following the close of the Umpqua Measuring Period and (3) Umpqua does not elect to pursue a Decline Adjustment or Cash Fill Option as set forth below; provided, however, that, if Umpqua effects a stock dividend, stock split, combination, exchange of shares or similar transaction after the date hereof and prior to the date on which the Umpqua Measuring Price is determined, the provisions of this Section 11.1(e) shall be appropriately adjusted so that such event does not in and of itself trigger a termination right on behalf of NBB.

The following terms have the following meanings:

	(i)		“Umpqua Measuring Period” means the fifteen trading days ending on the fifth business day prior to the Effective Date.

	(ii)		“Umpqua Measuring Price” means the mathematical average of the per share closing prices of Umpqua Common Stock as quoted on the NASDAQ Global Select Market (as reported in The Wall Street Journal or another authoritative source) over the Umpqua Measuring Period.

Except as provided in Sexxxxx 00.0, XXX xhall not be entitled to terminate this Agreement pursuant to this Section 11.1(e) if Umpqua elects, no later than the close of business on the second succeeding Business Day after the later of (i) the close of the Umpqua Measuring Period and (ii) receipt of notice of NBB’s intent to terminate, either to:

(A) adjust the Exchange Ratio (a “Decline Adjustment”) such that the Exchange Ratio (carried to five significant digits) shall equal the quotient of (i) $32.15 divided by (ii) the Umpqua Measuring Price, or

(B) maintain the Exchange Ratio at 1.217 and pay additional consideration to NBB Shareholders (the “Cash Fill Option”) in cash (“Cash Consideration”) per share equal to $32.15 minus the product of (i) 1.217 times (ii) the Umpqua Measuring Price.

Upon Umpqua’s election of the Decline Adjustment or the Cash Fill Option, no termination shall have occurred pursuant to this Section 11.1(e) and this Agreement shall remain in effect in accordance with its terms (except as the term Exchange Ratio, as applicable, shall have been so modified), and in the event of a Decline Adjustment any references in this Agreement to “Exchange Ratio” shall thereafter be deemed to refer to the Exchange Ratio, as applicable, as adjusted pursuant to this Section 11.1(e) .

(f) By NBB or Umpqua, acting through its Board of Directors, if any Order permanently restraining, enjoining or otherwise prohibiting consummation of any of the Mergers shall

become final and non-appealable (whether before or after the approval by the shareholders of NBB or Umpqua).

11.2.2 If this Agreement is terminated by NBB or Umpqua pursuant to Section 11.1(g) (provided that no failure of any covenant, condition, representation or warranty on the part of Umpqua or within the reasonable control of NBB shall have proximately caused the failure of NBB shareholders to have approved the principal terms of this Agreement), by Umpqua pursuant to Section 11.1(c) or by NBB pursuant to Section 11.1(d), then NBB agrees to pay to Umpqua its reasonable expenses incurred in entering into and attempting to consummate the transaction up to a maximum of $500,000, to be paid within thirty (30) days after Umpqua’s request; provided, however, if Umpqua has terminated the Agreement as a result of NBB’s willful failure to comply with any material covenant set forth in Section 6, it agrees to pay Umpqua an additional $2,000,000, to be paid within thirty (30) days after Umpqua’s request. If this Agreement is terminated pursuant to Section 11.1(g) or Section 11.1(d), or by Umpqua pursuant to Section 11.1(c) and NBB enters into an Alternative Acquisition Transaction prior to the date that is 12 months from the date of termination and such Alternative Acquisition Transaction had been proposed prior to the date of the NBB shareholder meeting in the case of termination pursuant to Section 11.1(g) or prior to the date of termination in the case of termination pursuant to Section 11.1(c) or 11.1(d); and provided that in any of such events if, at the time of NBB’s shareholder meeting there was no material failure by Umpqua to comply with the covenants set forth in Section 7 and to satisfy the conditions set forth in Sections 9.7 and 9.9, then NBB will, within thirty (30) days after Umpqua’s request, pay Umpqua the sum of $5,000,000 (reduced by any amounts paid or payable pursuant to the first sentence of this paragraph).

This Section 11.2.3 shall be the sole remedy in favor of NBB for termination of this Agreement pursuant to the sections named in the first sentence, and NBB specifically waives the protections of any other legal or equitable remedies that otherwise might be available to NBB.

11.3 Price Protection. Except as provided in Section 11.4, in the event the Umpqua Measuring Price is greater than $33.58 the Exchange Ratio (carried to five significant digits) shall equal the quotient of (i) $40.87 divided by (ii) the Umpqua Measuring Price. If the Exchange Ratio is adjusted pursuant to this Section 11.3, this Agreement shall remain in effect in accordance with its terms (except as the Exchange Ratio shall have been so modified), and any references in this Agreement to “Exchange Ratio” shall thereafter be deemed to refer to the Exchange Ratio as adjusted pursuant to this Section 11.3.

11.4 Participation in Subsequent Transaction. From the date hereof through the Effective Time or the earlier termination of this Agreement, Umpqua shall not enter into any agreement with any unaffiliated third party concerning any purchase or acquisition of Umpqua or Umpqua Bank or substantially all of their respective assets by any unaffiliated third party through any type of corporate reorganization, stock acquisition or exchange, asset purchase or other similar transaction (an “Umpqua Transaction”), unless such Umpqua Transaction expressly provides (i) for the acquisition of NBB by Umpqua or a successor entity on the same terms and conditions as provided for in this Agreement and (ii) that if such Umpqua Transaction is completed before the Effective Time, the shareholders of NBB will be entitled to receive consideration in such transaction as if their shares of NBB had been converted into Umpqua Common Stock at the effective time of such transaction, without giving effect to any adjustment of the Exchange Ratio that would otherwise be required pursuant to Section 11.3 hereof.
