   without limitation, shares that could be issued pursuant to the exercise of
   stock options, warrants, or other such other security that, upon its
   exercise, could cause the issuance of shares of NWB common stock) and that
   NWB has made a good faith effort to obtain such shareholder's signature to
   this Voting Agreement.

2. VOTING AND OTHER MATTERS. Each Director/Officer and Principal Shareholder
   will vote or cause to be voted all shares of NWB's common stock that he

   refrain from any actions or omissions inconsistent with the foregoing, except
   as otherwise required by law, including, without limitation, the Directors'
   fiduciary duties to NWB and its shareholders.

3. NO TRANSFER. Until the earlier of the consummation of the Transaction or the
   termination of the Merger Agreement, each Director/Officer and Principal
   Shareholder will not sell, permit a lien or other encumbrance to be created

   with the NWB shareholders' meeting at which the Transaction is presented for
   shareholder approval) any Shares, unless all other parties to any such sale
   or other transaction enter into an agreement in form and substance

4. INDIVIDUAL OBLIGATIONS. The obligations of each Director/Officer and
   Principal Shareholder under this Voting Agreement are several and not joint.

5. MISCELLANEOUS.

   a. Severability. If any provision of this Voting Agreement or the application
      of such provision to any person or circumstances will be held invalid or
      unenforceable by a court of competent jurisdiction, such provision or
      application will be unenforceable only to the extent of such invalidity or
      unenforceability, and the remainder of the provision held invalid or
      unenforceable and the application of such provision to persons or
      circumstances, other than the party as to which it is held invalid, and
      the remainder of this Voting Agreement, will not be affected.

   b. Counterparts. This Voting Agreement may be executed in one or more
      counterparts, including facsimile counterparts, each of which will be
      deemed an original, but all of which taken together will constitute one
      and the same document.

   c. Governing Law; Venue. This Voting Agreement will be deemed a contract made
      under, and for all purposes will be construed in accordance with, the laws
      of the State of Oregon.

      relief and/or specific performance, as well as any other legal or
      equitable remedies PCBK may be entitled to.

                            NON-COMPETITION AGREEMENT

         This Non-Competition Agreement ("NON-COMPETITION AGREEMENT"), dated as
of August 17, 2005, is made by and among Pacific Continental Corporation, an
Oregon corporation ("PCBK"); Pacific Continental Bank, an Oregon state-chartered
bank ("PCB"); NWB Financial Corporation, a Washington corporation ("NWB");
Northwest Business Bank, a Washington state-chartered bank (the "BANK"); and the
undersigned director of NWB and/or the Bank (the "DIRECTOR").

                                    RECITALS

A. PCBK, PCB, NWB and the Bank have entered into a Plan and Agreement of Merger
   (the "MERGER AGREEMENT") dated as of the date hereof, pursuant to which NWB
   will merge with and into PCBK, and the Bank will merge with and into PCB
   (collectively such mergers are referred to as the "TRANSACTION").

B. The parties to this Non-Competition Agreement believe that the future success
   and profitability of PCBK and PCB following the Transaction (collectively,
   the "COMBINED ENTITY") require that the Director, upon the closing of the
   Transaction, not be affiliated in any substantial way with a Competing
   Business (as defined herein) for a reasonable period of time after closing of
   the Transaction.

                                    AGREEMENT

         In consideration of, and conditioned upon, the parties' performance
under the Merger Agreement, the Director agrees as follows:

1. DEFINITIONS. Capitalized terms not defined in this Non-Competition Agreement
   have the meaning assigned to those terms in the Merger Agreement. The
   following definitions also apply to this Non-Competition Agreement:

   a. Competing Business. "COMPETING BUSINESS" means any financial institution
      whose deposits are insured by the Federal Deposit Insurance Corporation
      (including without limitation, any start-up or other such financial
      institution in formation) or holding company thereof that competes or will
      compete within the Covered Area with the Combined Entity or any of its
      subsidiaries or affiliates.

   b. Covered Area. "COVERED AREA" means the geographical area of King County,
      Washington.

   c. Term. "TERM" means the period of time beginning on the Effective Date and
      ending eighteen months (18) months after the Effective Date.

2. PARTICIPATION IN COMPETING BUSINESS. Except as provided in Sections 5 or 6,
   during the Term, the Director may not become involved with a Competing
   Business or serve, directly or indirectly, a Competing Business in any
   manner, including without limitation,

<PAGE>

   (a) as a shareholder, member, partner, director, officer, manager, investor,
   organizer, founder, employee, consultant, agent, or representative, or (b)
   during the organization and pre-opening phases in the formation of a
   Competing Business.

3. NO SOLICITATION. During the Term, the Director may not, directly or
   indirectly, solicit or attempt to solicit or otherwise facilitate the
   solicitation of (a) any employees of the Combined Entity or any of its
   subsidiaries or affiliates to participate, as an employee or otherwise, in
   any manner in a Competing Business, or (b) any customers of the Combined
   Entity or its subsidiaries or affiliates to transfer their business to a
   Competing Business. Solicitation prohibited under this section includes
   solicitation by any means, including, without limitation, meetings, letters
   or other mailings, electronic communications of any kind, and internet
   communications.

4. CONFIDENTIAL INFORMATION. During and after the Term, the Director will not
   disclose any confidential information of NWB, the Bank, the Combined Entity
   or its subsidiaries or affiliates obtained by the Director while serving as a
   director of NWB, the Bank or the Combined Entity except in accordance with a
   judicial or other governmental order.

5. OUTSIDE COVERED AREA. Nothing in this Non-Competition Agreement prevents the
   Director from becoming involved, as a shareholder, member, partner, director,
   officer, manager, investor, organizer, founder, employee, consultant, agent,
   representative, or otherwise, with a Competing Business that has no
   operations in the Covered Area.

6. PERMITTED INVESTMENTS. Nothing in this Non-Competition Agreement prevents the
   Director from owning 5% or less of any class of security of a Competing
   Business. To the extent the Director owns more than 5% of any class of
   security of a Competing Business as of the date hereof, such ownership shall
   not violate Section 2 if (a) the Director has disclosed such ownership on a
   schedule attached to this Non-Competition Agreement, and (b) the Director
   does not acquire additional shares of such Competing Business during the Term
   (other than pursuant to stock splits or stock dividends).

7. REMEDIES. Any breach of this Non-Competition Agreement by the Director will
   entitle the Combined Entity, together with its successors and assigns, to
   injunctive relief and/or specific performance, as well as to any other legal
   or equitable remedies to which they may be entitled.

8. GOVERNING LAW AND ENFORCEABILITY. This Non-Competition Agreement is governed
   by, and will be interpreted in accordance with, the laws of the State of
   Oregon. If any court determines that the restrictions set forth in this
   Non-Competition Agreement are unenforceable, then the parties request such
   court to reform these provisions to the maximum restrictions, term, scope or
   geographical area that such court finds enforceable.

9. COUNTERPARTS. The parties may execute this Non-Competition Agreement in one
   or more counterparts, including facsimile counterparts. All the counterparts
   will be construed together and will constitute one Agreement.

                                       2
<PAGE>

10. TERMINATION. If the Merger Agreement is terminated for any reason, this
    Agreement shall be null and void and of no effect.
