NOW, THEREFORE, in consideration of the promises and of the representations, warranties and covenants, agreements and conditions contained herein and in the Reorganization Agreement, the parties hereto agree as follows:

1

AGREEMENT

1.                                      AGREEMENTS OF SHAREHOLDER

1.1.                            Agreement to Vote.  At any meeting of shareholders of First Business Bank and/or FB Bancorp to approve the Stock Purchase, the Merger, the Reorganization Agreement and the transactions contemplated thereby, Shareholder shall vote or cause to be voted all shares of: (i) common stock of FB Bancorp, no par value per share (“FB Bancorp Stock”) and (ii) common stock of First Business Bank, $5.00 par value per share (“First Business Bank Common Stock” and together with FB Bancorp Stock, “FBB Stock”), owned by Shareholder and any other shares of FBB Stock hereafter acquired by Shareholder in favor of, and to approve, the principal terms of the Stock Purchase, Bank Holding Company Formation, Merger and any other matter contemplated by the Reorganization Agreement which requires the approval of the shareholders of First Business Bank and/or FB Bancorp.

1.2.                            Restrictions on Dispositions.  Shareholder agrees that, except with the prior written consent of 1st Pacific Bancorp, which may be withheld in its sole and absolute discretion, Shareholder will not pledge nor otherwise encumber, sell, assign or otherwise dispose of any shares of FBB Stock currently owned or acquired by Shareholder after the date of this Agreement.

1.3.                            Cooperation.  Shareholder agrees to cooperate fully with 1st Pacific in connection with the Bank Holding Company Formation and the Stock Purchase, including providing all information reasonably requested by the regulatory authorities on a timely basis in connection with Shareholder’s applications for approval as the controlling shareholder of the Surviving Bank Holding Company.

1.4.                            Covenant to Elect Former 1st Pacific Directors.  Pursuant to Section 2.4 of the Reorganization Agreement, two board members of 1st Pacific Bancorp immediately prior to the effective time of the Merger (“1st Pacific Directors”) will be invited to join the board of directors of Surviving Corporation, which shall become the directors of Surviving Bank Holding Company.  Shareholder agrees to vote, or cause to be voted, all shares of FBB Stock owned by Shareholder and any other shares of FBB Stock hereafter acquired by Shareholder, from time to time and at all times, in whatever manner as shall be necessary to ensure that at each annual or special meeting of shareholders at which an election of directors is held or pursuant to any written consent of the shareholders, the 1st Pacific Directors shall be elected to the board of directors of Surviving Corporation and Surviving Bank Holding Company; provided however, that such obligation shall only apply if the 1st Pacific Directors are nominated for re-election by the Surviving Corporation’s board of directors and they consent to serve; and provided further, that such obligation shall terminate upon the expiration of the Earn Out Period (as defined in the Reorganization Agreement).

1.5.                            Reasonable Restrictions.  Shareholder agrees to accept all reasonable regulatory restrictions imposed by any Federal or state banking regulator including, but not limited to, the Office of the Comptroller of the Currency, the Federal Deposit Insurance Corporation, the Board of Governors of the Federal Reserve System and the California Department of Financial Institutions, which regulates 1st Pacific Bank or First Business Bank, or any of their respective holding companies or subsidiaries, as the case may be, in connection with the Stock Purchase and the Holding Company Formation; provided, however, Shareholder shall not be obligated to

2

consummate the Stock Purchase or the Bank Holding Company Formation to the extent that Shareholder reasonably determines, in good faith, that any one or more restrictions, individually or when aggregated, as in effect or to be in effect as of the closing of the Bank Holding Company Merger, with respect to Shareholder would be material and adverse to Shareholder’s financial condition or business plans, it being understood and agreed that any regulatory requirement to increase Shareholder’s financial commitment to the consummation of the Bank Holding Company Formation and Stock Purchase beyond fifteen million dollars ($15,000,000) shall be deemed material and adverse to Shareholder.

1.6.                            General Conduct.  During the period from the date of this Agreement to the Effective Time (as defined in the Reorganization Agreement), except with the written consent of 1st Pacific Bancorp and 1st Pacific Bank, which may be withheld in their sole and absolute discretion, Shareholder will not voluntarily take any action that would: (i) adversely affect the ability of Shareholder, First Business Bank or FB Bancorp to obtain the Regulatory Approvals (as defined in the Reorganization Agreement) or materially increase the period of time necessary to obtain such approvals; (ii) adversely affect his ability to perform his covenants and agreements under this Agreement; (iii) result in the representations and warranties contained in Article V of the Reorganization Agreement not being true and correct on the date of this Agreement or at any future date on or prior to the Closing Date (as defined in the Reorganization Agreement) or in any of the conditions set forth in Article IX of the Reorganization Agreement not being satisfied; or (iv) cause or allow (to the extent of Shareholder’s power and authority as a shareholder) First Business Bank or FB Bancorp to take any action that would result in the representations and warranties contained in Article V of the Reorganization Agreement not being true and correct on the date of this Agreement or at any future date on or prior to the Closing Date (as defined in the Reorganization Agreement) or in any of the conditions set forth in Article IX of the Reorganization Agreement not being satisfied.
