The Articles of Incorporation and Bylaws of APB will be the Articles of Incorporation and Bylaws of Surviving Bank. From and after the Effective Time, the

Surviving Bank shall possess all the rights, powers, privileges and franchises and be subject to all of the obligations, liabilities, restrictions and disabilities of APB and UB Subsidiary.

2.1.2 Subject to the satisfaction or waiver of the conditions set forth in Section 8 and Section 9, the Merger shall become effective upon the occurrence of the filing of the Agreement of Merger with the Secretary of State of the State of California as required under the CGCL, or such later date and time as may be set forth in such filings (the time the Merger becomes effective on the Effective Date being referred to as the "Effective Time").

2.1.3 At and as of the Effective Time, each outstanding share of UB Subsidiary common stock shall be converted into one share of the Surviving Bank with the same rights, powers and privileges as the shares so converted and shall constitute the only outstanding shares of capital stock of the Surviving Bank.

2.1.4 At and as of the Effective Time, automatically by virtue of the Merger and without any action on the part of any Person, (A) each share of APB Common Stock (other than Dissenters' Shares) issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive $10.00 in cash without interest (the "Cash Consideration") and (B) all shares of APB Common Stock that are "dissenting shares" within the meaning of CGCL § 1300 ("Dissenters' Shares") shall be converted into the right to receive payment with respect thereto in accordance with the provisions of the CGCL and shall not be converted into or represent a right to receive Cash Consideration unless and until such shares have lost their status as dissenting shares under CGCL § 1300, at which time each such share shall be converted into the right to receive the Cash Consideration. As of the Effective Time, all such shares of APB Common Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and shall thereafter represent only the right to receive the Cash Consideration to be paid in accordance with Section 2.2.

2.1.5 Following the receipt of all approvals required to effect the Merger and the Second Merger, and proximately prior to the Effective Time, consistent with the APB 2007 Restricted Share Plan, by virtue of the Merger and without any action on the part of any holder of an award of restricted shares of APB Common Stock granted pursuant to the provisions of the APB 2007 Restricted Share Plan (an "APB Restricted Share Award"), each outstanding APB Restricted Share Award shall become fully vested and the associated shares of APB Common stock shall be issued and become outstanding.

2.1.6 Immediately following the Merger, Umpqua shall cause the Surviving Bank to be merged with and into Umpqua, with Umpqua the resulting bank.

2.2 Exchange Procedures.

2.2.1 Prior to the Effective Date, Umpqua shall appoint an exchange agent reasonably acceptable to APB (the "Exchange Agent") for the purpose of exchanging shares of APB Common Stock, whether in certificate or electronic form (other than Dissenters' Shares), for Cash Consideration as required by Section 2.1. Prior to the Effective Date, Umpqua will issue and deliver to the Exchange Agent the Total Cash Consideration.

2.2.2 Promptly after the Effective Time, Umpqua shall cause the Exchange Agent to mail to each holder of record of shares (other than holders of Dissenters' Shares) a notice advising such holders of the effectiveness of the Merger, including appropriate transmittal materials specifying that delivery shall be effected, and risk of loss and title to certificates for shares of APB Common Stock ("APB Certificates") shall pass, only upon delivery of the APB Certificates (or affidavits of loss in lieu thereof, as provided in Section 2.3.5) and instructions for surrendering the APB Certificates (or affidavits of loss in lieu thereof) to the Exchange Agent. Upon surrender for cancellation to the Exchange Agent of one or more APB Certificates, accompanied by a duly executed letter of transmittal in proper form, the Exchange Agent shall deliver to each holder of such surrendered APB Certificates checks for payment of Cash Consideration, less any taxes required to be withheld with respect thereto.

2.2.3 Until APB Certificates have been surrendered and exchanged for Cash Consideration as herein provided, each outstanding APB Certificate shall be deemed, for all corporate purposes of Umpqua, to represent only the amount of Cash Consideration into which the shares of APB Common Stock were exchanged pursuant to Section 2.1.4. In the event of a transfer of ownership of shares of APB Common Stock that is not registered in the transfer records of APB, a check for the Cash Consideration to be paid upon due surrender of the APB Certificate may be paid to such a transferee if the APB 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.

2.2.4 Cash delivered to the Exchange Agent (together with any interest thereon) and not issued pursuant to this Section 2.2 at the end of twelve months from the Effective Date shall be returned to Umpqua, subject to California escheatment laws, in which event the persons entitled thereto shall look only to Umpqua for payment thereof.

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

2.3 Dissenters' Shares. Any Dissenting Shareholder who shall be entitled to be paid the fair market value of such shareholder's shares of APB Common Stock, as provided in Section 1300 of the CGCL, shall not be entitled to Cash Consideration in respect thereof unless and until such Dissenting Shareholder shall have failed to perfect or shall have effectively withdrawn or lost such Dissenting Shareholder's right to dissent from the Merger under the CGCL, and shall be entitled to receive only the payment provided for by Section 1300 of the CGCL with respect to such Dissenters' Shares.

3. DISCLOSURE SCHEDULES.

On or prior to the date hereof, APB has delivered to Umpqua a schedule and Umpqua has delivered to APB a schedule (each respectively, its "Disclosure Schedule") setting forth, among other things, items, the disclosure of which are necessary or appropriate either in response to an express

disclosure requirement contained in a provision hereof or as an exception to one or more representations or warranties contained in Section 4 or Section 5 or to one or more of its respective covenants contained in Section 6 or Section 7; provided, however, the mere inclusion of an item in a Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission by a party that such item represents a material exception, fact, event or circumstance, or that such item is reasonably likely to have, or result in, a Material Adverse Effect on the party making the representation. The Disclosure Schedules shall be subject to the confidentiality requirements of the Confidentiality Agreement. All information received by APB from Umpqua pursuant to the terms of this Agreement shall be kept in strictest confidence and will be used only for the purpose of completing the transactions contemplated by this Agreement.

(c) Except as disclosed in Section 4.22(c) of the APB Disclosure Schedule, there are no Contracts, agreements, arrangements, undertakings or commitments maintained or agreed to by either of APB or provision of any Employee Benefit Plan that provide for or could result in the payment to any APB employee or director or former employee or director of any money or other property rights or that would accelerate the vesting or payment of such amounts or rights to any such person as a result of the consummation of transactions contemplated by this Agreement. No such payment or acceleration set forth in Section 4.22(c) of the APB Disclosure Schedule could be characterized as an "excess parachute payment" within the meaning of Code Section 280G.

(d) APB is, and has since inception been, in substantial compliance in all material respects with, and each Employee Benefit Plan is and has been operated substantially in accordance with its provisions and in compliance with the applicable laws, rules and regulations governing such Employee

In particular, but without limitation, each Welfare Benefit Plan is in material compliance with federal law, including without limitation the health care continuation requirements of the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA"). Except as set forth in Section 4.22(f) of the APB Disclosure Schedule, no Employee Benefit Plan provides benefits, including without limitation death or medical benefits (whether or not insured), with respect to current or former employees or directors of APB beyond their retirement or other termination of service, other than (i) coverage mandated by applicable law, (ii) any deferred compensation benefits fully accrued as liabilities on the books of APB or (iii) benefits the full cost of which is borne by the current or former employee or director (or beneficiary thereof).

4.23 Labor and Employment. There is no labor strike, material dispute, slowdown or stoppage pending or, to the Knowledge of APB, threatened against APB, and to the Knowledge of APB there is no activity involving employees of APB or any APB Subsidiary to certify a collective bargaining unit or engage in other organizational activity. Neither APB nor any APB Subsidiary is a party to or is bound by any collective bargaining agreement, contract or other agreement or understanding with a labor union or labor organization, nor is APB or any APB Subsidiary the subject of a proceeding asserting that it or any such APB Subsidiary has committed an unfair labor practice (within the meaning of the National Labor Relations Act) or seeking to compel APB or any APB Subsidiary to bargain with any labor organization as to wages or conditions of employment.

4.24 Allowance for Loan Losses. APB's allowance for loan losses, as established from time to time, equals or exceeds the amount required of APB as determined (i) by internal policies and

procedures of APB for determining the allowance for loan losses; (ii) by applicable FDIC rules and guidance; and (iii) pursuant to GAAP. Except as set forth on Section 4.24 of the APB Disclosure Schedule, since December 31, 2011, APB has not reversed any provision taken for loan losses. APB has properly accounted for all impaired loans in accordance with internal policies of APB and in accordance with SFAS 114 in all material respects. The allowance for loan losses reflected on the APB Financial Statements, as of their respective dates, is adequate in all material respects under the requirements of GAAP to provide for reasonably estimated inherent losses on outstanding loans.

4.25 Repurchase Agreements. With respect to all agreements pursuant to which APB has purchased securities subject to an agreement to resell, if any, APB has a valid, perfected first lien or security interest in or evidence of ownership in book entry form of the government securities or other collateral securing the repurchase agreement, and the value of such collateral equals or exceeds the amount of the debt secured thereby.

4.27 Interests of Directors and Others. No officer or director of APB has any material interest in any assets or property (whether real or personal, tangible or intangible), of or used in the business of APB other than as an owner of outstanding securities or deposit accounts of APB, or as borrowers under loans fully performing in accordance with their terms, which terms are no more favorable than those available to unaffiliated parties made at or about the same time.

4.28 Fairness Opinion; Brokers and Finders. APB has received the opinion of its financial advisor, ▇▇▇▇▇, ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇, to the effect that, as of the date hereof, the Cash Consideration to be received by the holders of APB Common Stock in the Merger is fair to such holders from a financial point of view. A true and complete copy of such written opinion will be delivered to Umpqua as soon as possible. Except for the fees and related costs payable to ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇, pursuant to an engagement letter dated January 24, 2012, a true and correct copy of which has been provided to Umpqua, no action has been taken by APB that would give rise to any valid claim against any party hereto for a brokerage commission, finder's fee or other like payment with respect to the transactions contemplated by this Agreement.

4.29 Bank Secrecy Act; Anti-Money Laundering and OFAC and Customer Information; Patriot Act; Transactions with Affiliates. APB is not aware of, has not been advised of, and has no reason to believe that any facts or circumstances exist, which would cause APB to be deemed (i) to be operating in violation in any material respect of the Bank Secrecy Act, the Patriot Act, any order issued with respect to anti-money laundering by the U.S. Department of the Treasury's Office of Foreign Assets Control, or any other applicable anti-money laundering statute, rule or regulation; or (ii) not to be in satisfactory compliance in any material respect with the applicable privacy and customer information requirements contained in any federal and state privacy laws and regulations, including, without limitation, in Title V of the ▇▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Act of 1999 and the regulations promulgated thereunder, as well as the provisions of the information security program adopted by APB pursuant to 12 C.F.R. Part 364. APB is not aware of any facts or circumstances that would cause it to believe that any non-public customer information has been disclosed to or accessed by an unauthorized third party in a manner that would cause APB or any APB Subsidiary to undertake any material remedial action. The APB Board has adopted and implemented an anti-money laundering program that contains adequate and appropriate customer identification verification procedures that comply with Section 326 of the Patriot Act and such anti-money laundering program meets the requirements in all material respects of Section 352 of the Patriot Act and the regulations thereunder, and APB has complied in all material respects with any requirements to file reports and other necessary documents as required by the Patriot Act and the regulations thereunder. APB, in all material respects, has timely and accurately filed all currency

transaction reports required by the Bank Secrecy Act. APB has no covered transactions with affiliates within the meaning of Sections 23A and 23B of the Federal Reserve Act.

4.30 Risk Management Instruments. All material interest rate swaps, caps, floors, option agreements, futures and forward contracts and other similar risk management arrangements, whether entered into for APB's own account, or for the account of one or more of APB's customers (all of which are listed on Section 4.30 of the APB Disclosure Schedule), were entered into (i) in accordance with prudent business practices and all applicable laws, rules, regulations and regulatory policies and (ii) with counterparties believed to be financially responsible at the time; and each of them constitutes the valid and legally binding obligation of APB, enforceable in accordance with its terms (except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and similar laws of general applicability relating to or affecting creditors' rights or by general equity principles), and is in full force and effect. Neither APB nor, to APB's Knowledge, any other party thereto, is in breach of any of its obligations under any such agreement or arrangement.

Date:

(a) By the mutual written consent of Umpqua and APB;

(b) By either party if its Board of Directors so determines by vote of a majority of the members of its entire Board of Directors, upon written notice to the other party, if at the time of such notice the Merger shall not have become effective by November 30, 2012 (or such later date as shall have been agreed to in writing by Umpqua and APB) except to the extent that the failure of the Merger to be consummated arises out of or results from the knowing action or inaction of the party seeking to terminate, which action or inaction is in violation of its obligations under this Agreement;
