Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On December 8, 2011, California United Bank (the “Company” or “CUB”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Premier Commercial Bancorp (OTCBB:PCBP) and Premier Commercial Bank, N.A. ( collectively “PCB”), pursuant to which, among other things, Premier Commercial Bank will be merged into CUB and Premier Commercial Bancorp will be merged into a newly formed corporation established to become a bank holding company for CUB (“CU Bancorp”), subject to regulatory and shareholder approval (collectively the “Merger Transactions”). In conjunction with the acquisition of PCB, CUB intends to complete a holding company reorganization immediately prior to the Merger Transactions.

Subject to the terms and conditions of the Merger Agreement which has been unanimously approved by the boards of directors of CUB, CU Bancorp and PCB, upon the completion of the merger of Premier Commercial Bancorp into CU Bancorp, each issued and outstanding share of Premier Commercial Bancorp common stock will be converted into approximately one share of CU Bancorp common stock, with cash to be paid in lieu of the issuance of fractional shares of CU Bancorp’s common stock.

CU Bancorp will issue 3,721,442 shares (the “share consideration”) of its common stock to the shareholders of Premier Commercial Bancorp. The number of CU Bancorp shares which will be issued to shareholders of Premier Commercial Bancorp is subject to certain adjustments if the weighted average price of CUB common stock over a 20 business day period ending ten days prior to the effective time of the merger (“Closing Price”) increases or decreases by more than 10%, respectively, from the weighted average of CUB common stock over the 20 business days prior to the announcement (“Announcement Price”) of the transaction (the “adjusted share consideration”). The precise exchange (the “Exchange Ratio”) will be determined by dividing the share consideration or the adjusted share consideration by the number of shares of Premier Commercial Bancorp’s common stock outstanding immediately prior to the effective time of the Merger Transactions. The acquisition is valued at approximately $38.1 million, based on the price of CUB common stock on December 8, 2011.

The receipt of CU Bancorp common stock by shareholders of Premier Commercial Bancorp is expected to be structured as a tax-free exchange.

All Premier Commercial Bancorp outstanding stock options will become fully vested prior to the Merger. At the effective time of the merger, CUB will pay holders of Premier Commercial Bancorp stock options with exercise prices lower than the value of the per share merger consideration (the product of (i) the Exchange Ratio and (ii) the Closing Price), an amount equal to the difference between the exercise price of the options and the per share merger consideration.

The Merger Agreement contains representations, warranties and covenants of CUB and PCB, including, among others, covenants: (i) to conduct their respective businesses in the ordinary course during the period between the execution of the Merger Agreement and consummation of the Merger; and (ii) not to engage in certain kinds of transactions during such period.

CUB and PCB have each also agreed not to (i) solicit proposals relating to alternative business combination transactions or (ii) subject to certain exceptions, enter into discussions or negotiations or provide confidential information in connection with any proposals for alternative business combination transactions.

The consummation of the Merger is subject to various conditions, including but not limited to (i) the receipt of regulatory approvals; (iii) formation of the bank holding company and all requisite regulatory and shareholder approvals; (iii) the requisite approval of CU Bancorp shareholders, CUB shareholders and PCB Shareholders; (iv) absence of any law or order prohibiting the consummation; and (v) no material adverse change to either party. In addition, each party’s obligations to consummate the Merger is subject to certain other conditions, including: (i) subject to the standards set forth in the Merger Agreement, the accuracy of the representations and warranties of the other party; (ii) compliance of the other party with its covenants in all material respects; and (iii) delivery of an opinion of a law firm relating to the U.S. federal income tax code treatment of the CU Bancorp common stock to be received by PCB shareholders in the Merger Transactions.

The boards of directors of CUB, CU Bancorp and Premier Commercial Bancorp have adopted resolutions recommending the approval and adoption of the Merger Agreement by their shareholders and each party has agreed to hold a shareholder meeting to put these matters before their respective shareholders for their consideration.

In connection with entering into the Merger Agreement, directors of PCB entered into a shareholder voting agreement (the “PCB Shareholder Agreement”) with CUB. Pursuant to the Shareholder Agreement, the directors have agreed, among other things, to vote their shares of Premier Commercial Bancorp common stock in favor of the Merger and the Merger Agreement at any Premier Commercial Bancorp shareholder meeting that is held to vote on the Merger Transactions and the Merger Agreement. In addition, the directors have agreed not to transfer, except under limited circumstances, any of their shares of Premier Commercial Bancorp common stock prior to the consummation of the Merger. In addition, the Chairman/CEO and President/Chief Operating Officer, along with all PCB Directors, have agreed to enter into Non Competition and/or Non Solicitation Agreements with CUB for terms varying from two years to one year.

Additionally, directors of CUB entered into a shareholder voting agreement (the “CUB Shareholder Agreement”) with PCB. Pursuant to the Shareholder Agreement, the directors have agreed, among other things, to vote their shares of CUB common stock in favor of the Merger Transactions and the Merger Agreement at any CUB or CU Bancorp shareholder meeting that is held to vote on the Merger Transactions and the Merger Agreement. In addition, the directors have agreed not to transfer, except under limited circumstances, any of their shares of CUB common stock prior to the consummation of the Merger Transactions.

The Merger Agreement provides certain termination rights for both CUB and PCB, and further provides that upon termination of the Merger Agreement under certain circumstances, PCB will be obligated to pay CUB a termination fee of $1,000,000 and CUB will be obligated to pay PCB a termination fee of $500,000.

Subject to the approval of the shareholders of CU Bancorp, CUB and Premier Commercial Bancorp, regulatory approvals and other customary closing conditions, the parties anticipate completing the Merger in the second quarter of 2012.

The foregoing descriptions of the Merger Agreement and Shareholder Agreement are not complete and are qualified in their entirety by reference to the Merger Agreement and Shareholder Agreement, copies of which are filed as Exhibit 2.1 hereto and are hereby incorporated into this report by reference. The Merger Agreement, which has been included to provide investors with information regarding its terms, contains representations and warranties of each of CUB and PCB. The assertions embodied in those representations and warranties were made for purposes of the Merger Agreement and are subject to

qualifications and limitations agreed upon by the respective parties in connection with negotiating the terms of the Merger Agreement. In addition, certain representations and warranties were made as of a specific date, may be subject to a contractual standard of materiality different from what a shareholder might view as material, or may have been used for purposes of allocating risk between the respective parties rather than establishing matters as facts. Investors should not rely on the representations, warranties or covenants or any description thereof as characterizations of the actual state of facts or condition of the CUB or any of its subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in public disclosures by CUB. Investors should read the Merger Agreement and the Shareholder Agreement together with the other information concerning CUB that CUB publicly files in reports and statements with the Federal Deposit Insurance Corporation (the “FDIC”).

In connection with the proposed Merger with Premier Commercial Bancorp, CU Bancorp will file with the Securities and Exchange Commission (the “SEC”) and the California Department of Corporations, a registration statement that will include a joint proxy statement of California United Bank, CU Bancorp and Premier Commercial Bancorp, which also constitutes a prospectus of CU Bancorp and California United Bank. In addition, in connection with the bank holding company reorganization, CU Bancorp and CUB will file with the SEC, the California Department of Corporations and the California Department of Financial Institutions a registration statement that will include a proxy/prospectus of CU Bancorp and CUB. CU Bancorp, California United Bank and Premier Commercial Bancorp will each mail the proxy statement/prospectus to their respective shareholders. Investors and security holders are urged to read the proxy statement/prospectus regarding the proposed transactions when it becomes available, as well as any amendments or supplements to those documents, because it will contain important information.

In addition, certain statements may be contained in our future filings with the FDIC, in press releases and in oral and written statements made by us or with our approval that are not statements of historical fact and constitute forward-looking statements within the meaning of the Act. Examples of forward-looking statements include, but are not limited to: (i) projections of revenues, expenses, income or loss, earnings or loss per share, the payment or nonpayment of dividends, capital structure and other financial items; (ii) statements of our plans, objectives and expectations or those of our management or Boards of Directors, including those relating to products or services; (iii) statements of future economic performance; and (iv) statements of assumptions underlying such statements.

These factors include (1) difficult and adverse conditions in the global and domestic capital and credit markets and the state of California, (2) continued volatility and further deterioration of the capital and credit markets, (3) significant costs or changes in business practices required by new banking laws or regulations, (4) a more adverse than expected decline, a “double dip” recession, or continued weakness in general business and economic conditions, which may affect, among other things, the level of nonperforming assets, charge-offs and provision expense, (5) changes in market rates and prices which may adversely impact the value of financial products, (6) changes in the interest rate environment and market liquidity which may reduce interest margins and impact funding sources, (7) increased competition, (8) changes in the financial performance and/or condition of the Bank’s borrowers, (9) increases in Federal Deposit Insurance Corporation premiums due to market developments and regulatory changes, (10) earthquake, fire, pandemic or other natural disasters, (11) changes in accounting policies or procedures as may be required by the Financial Accounting Standards Board or regulatory agencies, and (12) our success at managing the risks involved in the foregoing.

Forward-looking statements speak only as of the date they are made, and we do not undertake any obligation to update forward-looking statements to reflect circumstances or events that occur after the date the statements are made, or to reflect the occurrence of unanticipated events.

No supplement or amendment to such PC Bancorp Disclosure Schedule shall have any effect for the purpose of determining satisfaction of the conditions set forth in Article IX; provided, however, that the contents of any supplement or amendment shall not otherwise be deemed a breach of a representation or warranty, including for purposes of Section 11.2.2(A), unless such supplement or amendment contains a fact, circumstance or event that individually, or taken together with all other facts, circumstances and events has resulted in or has had, or is reasonably expected to have or result in a Material Adverse Effect.

PC Bancorp shall use all commercially reasonable efforts to obtain, as soon as practicable, all consents and approvals necessary or desirable for the consummation of the transactions contemplated by this Agreement.

6.10.1 PC Bancorp and PCB shall not, and shall cause their respective officers, directors, employees, investment bankers, financial advisors, attorneys, accountants, consultants, affiliates and other agents (collectively, the “Representatives”) not to, directly or indirectly, (i) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal which constitutes, or could reasonably be expected to lead to, an Acquisition Proposal; (ii) participate in any discussions or negotiations regarding any Acquisition Proposal or furnish, or otherwise afford access, to any Person (other than CUB) any information or data with respect to PC Bancorp or PCB or otherwise relating to an Acquisition Proposal; (iii) release any Person from, waive any provisions of, or fail to enforce any confidentiality agreement or standstill agreement to which PC Bancorp or PCB is a party; or (iv) enter into any agreement, agreement in principle or letter of intent with respect to any Acquisition Proposal or approve or resolve to approve any Acquisition Proposal or any agreement, agreement in principle or letter of intent relating to an Acquisition Proposal. Any violation of the foregoing restrictions by PC Bancorp or PCB or any Representative, whether or not such Representative is so authorized and whether or not such Representative is purporting to act on behalf of PC Bancorp or PCB or otherwise, shall be deemed to be a breach of this Agreement by PC Bancorp and PCB. PC Bancorp and PCB shall, and shall cause each of their respective Representatives to, immediately cease and cause to be terminated any and all existing discussions, negotiations, and communications with any Persons with respect to any existing or potential Acquisition Proposal.

For purposes of this Agreement, “Acquisition Proposal” shall mean any inquiry, offer or proposal (other than an inquiry, offer or proposal from CUB), whether or not in writing, contemplating, relating to, or that could reasonably be expected to lead to, an Acquisition Transaction. For purposes of this Agreement, “Acquisition Transaction” shall mean (A) any transaction or series of transactions involving any merger, consolidation, recapitalization, share exchange, liquidation, dissolution or similar transaction involving PC Bancorp or PCB; (B) any transaction pursuant to which any third party or group acquires or would acquire (whether through sale, lease or other disposition), directly or indirectly, any assets of PC Bancorp or PCB representing, in the aggregate, fifteen percent (15%) or more of the assets of PC Bancorp and PCB on a consolidated basis; (C) any issuance, sale or other disposition of (including by way of merger, consolidation, share exchange or any similar transaction) securities (or options, rights or warrants to purchase or securities convertible into, such securities) representing ten percent

(10%) or more of the votes attached to the outstanding securities of PC Bancorp or PCB; (D) any tender offer or exchange offer that, if consummated, would result in any third party or group beneficially owning ten percent (10%) or more of any class of equity securities of PC Bancorp or PCB; or (E) any transaction which is similar in form, substance or purpose to any of the foregoing transactions, or any combination of the foregoing.

6.10.2 Notwithstanding Section 6.10.1, PC Bancorp may take any of the actions described in clause (ii) of Section 6.10.1 if, but only if: (i) PC Bancorp has received a bona fide unsolicited written Acquisition Proposal that did not result from a breach of this Section 6.10; (ii) PC Bancorp Board determines in good faith, after consultation with, and having considered the advice of, its outside legal counsel and its independent financial advisor, that (A) such Acquisition Proposal constitutes, or is reasonably likely to lead to, a Superior Proposal and (B) the failure to take such actions would be inconsistent with its fiduciary duties to PC Bancorp’s shareholders under applicable law; (iii) PC Bancorp has provided CUB with at least five (5) Business Days’ prior notice of such determination; and (iv) prior to furnishing or affording access to any information or data with respect to PC Bancorp or PCB or otherwise relating to an Acquisition Proposal, PC Bancorp or PCB receives from such Person a confidentiality agreement with terms no less favorable to PC Bancorp or PCB than those contained in the Confidentiality Agreement. PC Bancorp and PCB shall promptly provide to CUB any non-public information regarding PC Bancorp or PCB provided to any other Person that was not previously provided to CUB, such additional information to be provided no later than the date of provision of such information to such other party.

For purposes of this Agreement, “Superior Proposal” shall mean any bona fide written proposal (on its most recently amended or modified terms, if amended or modified) made by a third party to enter into an Acquisition Transaction on terms that PC Bancorp Board determines in its good faith judgment, after consultation with and having considered the advice of outside legal counsel and a financial advisor: (i) would result in a transaction that (A) involves consideration to the holders of the shares of PC Bancorp Common Stock that is more favorable, from a financial point of view, than the consideration to be paid to PC Bancorp’s shareholders pursuant to this Agreement, considering, among other things, the nature of the consideration being offered and any material regulatory approvals or other risks associated with the timing of the proposed transaction beyond or in addition to those specifically contemplated hereby, and which proposal is not conditioned upon obtaining additional financing and (B) is, in light of the other terms of such proposal, more favorable to PC Bancorp’s shareholders than the Merger and the transactions contemplated by this Agreement; and (ii) is reasonably likely to be completed on the terms proposed, in each case taking into account all legal, financial, regulatory and other aspects of the proposal.

6.10.3 PC Bancorp shall promptly (and in any event within twenty-four (24) hours) notify CUB in writing if any proposals or offers are received by, any information is requested from, or any negotiations or discussions are sought to be initiated or continued with, PC Bancorp or any PC Bancorp Representatives, in each case in connection with any Acquisition Proposal, and such notice shall indicate the name of the Person initiating such discussions or negotiations or making such proposal, offer or information request and the material terms and conditions of any proposals or offers (and, in the case of written materials relating to such proposal, offer, information request, negotiations or discussion, providing copies of such materials (including

e-mails or other electronic communications) unless: (i) such materials constitute confidential information of the party making such offer or proposal under an effective confidentiality agreement; (ii) disclosure of such materials jeopardizes the attorney-client privilege; or (iii) disclosure of such materials contravenes any law, rule, regulation, order, judgment or decree. PC Bancorp and PCB agree that they shall keep CUB informed, on a current basis, of the status and terms of any such proposal, offer, information request, negotiations or discussions (including any amendments or modifications to such proposal, offer or request).

6.10.4 Subject to Section 6.10.5, neither the PC Bancorp Board nor any committee thereof shall: (i) withdraw, qualify or modify, or propose to withdraw, qualify or modify, in a manner adverse to CUB in connection with the transactions contemplated by this Agreement (including the Merger), the PC Bancorp Recommendation (as defined in Section 8.2), or make any statement, filing or release, in connection with PC Bancorp Shareholders Meeting or otherwise, inconsistent with the PC Bancorp Recommendation (it being understood that taking a neutral position or no position with respect to an Acquisition Proposal shall be considered an adverse modification of the PC Bancorp Recommendation); (ii) approve or recommend, or propose to approve or recommend, any Acquisition Proposal; or (iii) enter into (or cause PC Bancorp or PCB to enter into) any letter of intent, agreement in principle, acquisition agreement or other agreement (A) related to any Acquisition Transaction (other than a confidentiality agreement entered into in accordance with the provisions of Section 6.10.2 or (B) requiring PC Bancorp or PCB to abandon, terminate or fail to consummate the Merger or any other transaction contemplated by this Agreement.

6.10.5 Notwithstanding Section 6.10.4, prior to the date of the PC Bancorp Shareholders Meeting, the PC Bancorp Board may approve or recommend to the shareholders of PC Bancorp a Superior Proposal and withdraw, qualify or modify the PC Bancorp Recommendation in connection therewith (a “PC Bancorp Subsequent Determination”) after the fourth (4th) Business Day following CUB’s receipt of a notice (the “Notice of Superior Proposal”) from PC Bancorp advising CUB that the PC Bancorp Board has decided that a bona fide unsolicited written Acquisition Proposal that it received (that did not result from a breach of this Section 6.10) constitutes a Superior Proposal (it being understood that PC Bancorp shall be required to deliver a new Notice of Superior Proposal in respect of any revised Superior Proposal from such third party or its Affiliates that PC Bancorp proposes to accept) if, but only if, (i) the PC Bancorp Board has reasonably determined in good faith, after consultation with and having considered the advice of outside legal counsel and a financial advisor, that the failure to take such actions would be inconsistent with its fiduciary duties to PC Bancorp’s shareholders under applicable law, (ii) during the four (4) Business Day period after receipt of the Notice of Superior Proposal by CUB, PC Bancorp and the PC Bancorp Board shall have cooperated and negotiated in good faith with CUB to make such adjustments, modifications or amendments to the terms and conditions of this Agreement as would enable PC Bancorp to proceed with the PC Bancorp Recommendation without a PC Bancorp Subsequent Determination; provided, however, that CUB shall not have any obligation to propose any adjustments, modifications or amendments to the terms and conditions of this Agreement, and (iii) at the end of such four (4) Business Day period, after taking into account any such adjusted, modified or amended terms as may have been proposed by CUB since its receipt of such Notice of Superior Proposal, PC Bancorp Board has again in good faith made the determination (A) in clause (i) of this Section 6.10.5 and (B) that such Acquisition Proposal constitutes a Superior Proposal.

Notwithstanding the foregoing, the changing, qualifying or modifying of the PC Bancorp Recommendation or the making of a PC Bancorp Subsequent Determination by the PC Bancorp Board shall not change the approval of the PC Bancorp Board for purposes of causing any Takeover Laws to be inapplicable to this Agreement and the Voting Agreements and the transactions contemplated hereby and thereby, including the Merger.

6.10.6 Nothing contained in this Section 6.10 shall prohibit PC Bancorp or the PC Bancorp Board from complying with PC Bancorp’s obligations required under Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act; provided, however, that any such disclosure relating to an Acquisition Proposal shall be deemed a change in the PC Bancorp Recommendation unless PC Bancorp Board reaffirms the PC Bancorp Recommendation in such disclosure.

6.11.1 PC Bancorp and PCB agree to consult with CUB with respect to its loan, litigation and real estate valuation policies and practices (including loan classifications and levels of reserves). PCB and PC Bancorp shall also consult with CUB with respect to the character, amount and timing of restructuring charges to be taken by each of them in connection with the transactions contemplated hereby and shall take such charges as CUB shall reasonably request and which are not inconsistent with GAAP, provided that no such actions need be effected until CUB shall have irrevocably certified to PC Bancorp that all conditions set forth in Article IX to the obligation of CUB to consummate the transactions contemplated hereby (other than the delivery of certificates or opinions) have been satisfied or, where legally permissible, waived.

6.11.2 Establishment of Accruals. PC Bancorp and PCB shall establish accruals for all severance benefits for terminated employees. If requested by CU Bancorp or CUB, on the second Business Day immediately prior to the Effective Time, PC Bancorp or PCB shall, consistent with GAAP, establish such additional accruals and reserves as may be necessary to conform its accounting and credit loss reserve practices and methods to those of CUB (as such practices and methods are to be applied to PC Bancorp or PCB from and after the Effective Time) and reflect CUB’s plans with respect to the conduct of PC Bancorp’s and PCB’s business following the Merger and to provide for the costs and expenses relating to the consummation by PC Bancorp and PCB of the transactions contemplated by this Agreement. The establishment of such accruals and reserves shall not, in and of itself, constitute a breach of any representation or warranty of PC Bancorp or PCB contained in the Agreement or constitute a Material Adverse Effect on the business (present or future), operations, or financial condition of PC Bancorp or PCB.

6.11.3 Transaction Expenses. Based upon the final bills or estimates of such final bills, PC Bancorp and PCB shall have paid all severance benefits under any PC Bancorp Employment Agreements that will terminate as a result of the transactions contemplated herein, other than severance benefits required to be deferred for a period not to exceed 6 months from termination in order to comply with Section 409A of the Code, and all fees and expenses of all attorneys, accountants and investment bankers of PC Bancorp and PCB (“Advisors”) for services rendered solely in connection with the transactions contemplated by this Agreement, including the fee to (collectively, the “PC Bancorp Transaction Expenses”) in full prior to the

PC Bancorp and PCB shall cooperate with CUB requests to obtain additional or updated appraisals on property securing loans of PC Bancorp and/or PCB during the period following receipt of all shareholder approvals of the transactions contemplated herein and the Effective Time.

PC Bancorp and PCB shall permit no more than two representatives of CUB who are subject to the Confidentiality Agreement to attend any meeting of the Board of Directors of PC Bancorp and/or PCB or the Executive and Loan Committees thereof as an observer (the “Observer”), provided that neither PC Bancorp nor PCB shall be required to permit the Observer to remain present during any confidential discussion of this Agreement, and the transactions contemplated hereby, any discussion necessary to maintain attorney/client privilege, or any third party proposal to acquire control of PC Bancorp or PCB or during any other matter that the respective Board of Directors has reasonably determined to be confidential with respect to CUB’s participation.

Subject to the terms and conditions herein provided, PC Bancorp and PCB agree to cooperate fully with CU Bancorp and CUB to consummate and make effective the Bank Holding Company Merger and the Bank Merger, as contemplated herein and in the Bank Holding Company Merger Agreement and the Bank Merger Agreement, attached hereto as Exhibit “C” and Exhibit “D,” respectively.

No supplement or amendment to such CUB Disclosure Schedule shall have any effect for the purpose of determining satisfaction of the conditions set forth in Article IX.

CUB and CU Bancorp shall use all commercially reasonable efforts to obtain as soon as practicable all consents and approvals necessary or desirable for the consummation of the transactions contemplated by this Agreement.

In the event that CUB or CU Bancorp determines that a condition to its obligation to complete the Merger cannot be fulfilled and that it will not waive that condition, it will promptly notify PC Bancorp and PCB.

cause their respective Representatives not to, directly or indirectly, (i) initiate, solicit, induce or knowingly encourage, or take any action to facilitate the making of, any inquiry, offer or proposal, whether or not in writing, contemplating, relating to, or that could reasonably be expected to lead to (A) any transaction or series of transactions involving any merger, consolidation, share exchange or similar transaction where CUB and/or CU Bancorp is not the surviving entity; or (B) any transaction or series of transactions facilitated by the FDIC or any transaction involving the FDIC, as receiver for a party thereto. Any violation of the foregoing restrictions by CU Bancorp or CUB or any Representative, whether or not such Representative is so authorized and whether or not such Representative is purporting to act on behalf of CU Bancorp or CUB or otherwise, shall be deemed to be a breach of this Agreement by CU Bancorp and CUB.

From the date hereof and for any period that the Undersigned is employed by or provides service for PCB, CUB or the Surviving Bank, the Undersigned, upon the reasonable request of PCB, CUB or the Surviving Bank, agrees to use his or her best efforts to retain the business of the Surviving Bank and promote the acquisition of new business by the Surviving Bank.

(b) Non-Solicitation of Officers or Employees. From the date hereof and for the period ending on the later of: (i) two years from and after the Effective Date or, (ii) two year from and after the date on which the Undersigned is no longer a Director or employee of CUB or the Surviving Bank, the Undersigned shall not, directly or indirectly, without the prior written consent of CUB or the Surviving Bank, on behalf of any Financial Institution, solicit or aid in the solicitation of any officer or employee or induce or attempt to induce any officer or employee of PCB, CUB and/or the Surviving Bank to terminate such Person’s relationships with PCB, CUB and/or the Surviving Bank.

The covenants of the Undersigned set forth in this Agreement shall be construed as independent of any other agreement or arrangement between the Undersigned, on the one hand, and CUB and the Surviving Bank on the other, and the existence of any claim or cause of action by the Undersigned against PCB, CUB and/or the Surviving Bank or any of their respective subsidiaries shall not constitute a defense to the enforcement of such covenants against the Undersigned.

4.1 Amendments. To the fullest extent permitted by law, this Agreement may be amended by agreement in writing of the parties hereto at any time.

4.2 Integration. This Agreement constitutes the entire agreement between the parties pertaining to the subject matter hereof and (except for other documents to be executed pursuant to the Merger Agreement) supersedes all prior agreements and understanding of the parties in connection therewith.

(a) This Agreement shall terminate automatically without further action in the event that the Merger Agreement is terminated prior to the Effective Time in accordance with its terms.

(b) Unless sooner terminated under subsection (a) of this Section 4.3, the obligations of the Undersigned under this Agreement shall terminate only on the mutual agreement of the Undersigned and CUB or the Surviving Bank.

4.4 Specific Performance. Undersigned acknowledges and agrees that irreparable injury will result to CUB and/or the Surviving Bank in the event of a breach of any of the provisions of this Agreement and that CUB and/or the Surviving Bank will have no adequate remedy at law with respect thereto. Accordingly, in the event of a material breach of this Agreement, and in addition to any other legal or equitable remedy CUB and/or the Surviving Bank may have, CUB and/or the Surviving Bank shall be entitled to the entry of a preliminary injunction and a permanent injunction (including, without limitation, specific performance) by a court of competent jurisdiction, to restrain the violation or breach thereof by Undersigned or any affiliates, agents or any other Persons acting for or with Undersigned in any capacity whatsoever,

and Undersigned submits to the jurisdiction of such court in any such action. In addition, after discussing the matter with Undersigned, CUB and/or the Surviving Bank shall have the right to inform any third party that CUB and/or the Surviving Bank reasonably believes to be, or to be contemplating, participating with Undersigned or receiving from Undersigned assistance in violation of this Agreement, of the terms of this Agreement and of the rights of CUB and/or the Surviving Bank hereunder, and that participation by any such Persons with Undersigned in activities in violation of Undersigned’s agreement with CUB and/or the Surviving Bank set forth in this Agreement may give rise to claims by CUB and/or the Surviving Bank against such third party.

4.5 Severability and Related Matters. If any provision of this Agreement shall be held by a court of competent jurisdiction to be unreasonable as to duration, activity or subject, it shall be deemed to extend only over the maximum duration, range of activities or subjects as to which such provision shall be valid and enforceable under applicable law. If any provisions shall, for any reason, be held by a court of competent jurisdiction to be invalid, illegal or unenforceable, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement, but this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein.

All waivers shall be in writing and signed by the party to be bound.

4.8 Assignment. This Agreement may be assignable by CUB only in connection with a sale of all or substantially all of their assets or a merger or reorganization in which they are not the surviving corporations. Any attempted assignment in violation of this prohibition shall be null and void.

4.9 Binding Effect; Benefit to Successors. This Agreement shall be binding upon the Undersigned and upon the Undersigned’s successor and representatives and shall inure to the benefit of CUB, the Surviving Bank and their respective successors, representatives and assigns.

CALIFORNIA UNITED BANK AND PREMIER COMMERCIAL BANCORP ANNOUNCE EXECUTION OF A DEFINITIVE AGREEMENT OF MERGER

Encino, CA. December 9, 2011 – The Boards of Directors of San Fernando Valley headquartered California United Bank (OTCBB:CUNB) and Orange County based Premier Commercial Bancorp (OTCBB: PCBP) announced today that the companies entered into a merger agreement providing for California United Bank or a holding company to be formed for California United Bank (“CU Bancorp”), to acquire Premier Commercial Bancorp and its subsidiary Premier Commercial Bank.

The acquisition is valued at approximately $38.1 million, with the consideration being paid in the form of common stock of a bank holding company to be established, subject to regulatory and shareholder approval, for California United Bank. At September 30, 2011, California United Bank had total assets of $791.7 million, total deposits of $671.9 million, total loans of $465.1 million and eight offices; Premier Commercial Bancorp had assets of $450 million, total deposits of $386 million, net loans of $307 million and two offices. Upon completion of the transaction, California United Bank will have over $1.2 billion in assets, over $1 billion in deposits and over $772 million in loans. The transaction is expected to be immediately accretive to the combined entity’s earnings per share, excluding one-time transaction expenses. This is the second merger transaction by six year old California United Bank which acquired California Oaks State Bank in December 2010.

California United Bank intends to continue to operate both of Premier Commercial Bank’s branches in Anaheim and Newport Beach/Irvine as full-service branches. The California United Bank Orange County Loan Production Office will be combined with the Premier Commercial Bank Newport Beach/Irvine branch. At close, California United Bank will operate eight full-service branches; located in the San Fernando Valley, Santa Clarita Valley, Los Angeles, the South Bay, Conejo Valley, Simi Valley, Anaheim and Newport Beach/Irvine; and one commercial lending office located in Glendale/San Gabriel Valley.

The merger has been approved by the Boards of Directors of all parties. The transaction is subject to approval by bank regulatory authorities and the shareholders of California United Bank, CU Bancorp and Premier Commercial Bancorp, as well as other customary conditions. The bank holding company formation for CU Bancorp is also subject to approval by bank regulatory authorities and the shareholders of California United Bank. The transaction is expected to close in the second quarter of 2012.

“The combination of CUNB and PCBP will create a strong banking presence in the Southern California Market, allowing us to reach additional clients and provide additional products, including SBA lending,” said David Rainer, President and Chief Executive Officer of California United Bank. “We have always believed that Orange County presents significant opportunities for our middle-market focused business lending. We are pleased that PCBP Chairman and

CEO Kenneth Cosgrove and Board member Robert Matranga will be joining our Board of Directors and assisting us as we partner with Premier Commercial Bank and its talented staff. We believe the strategic opportunities of this transaction are extremely attractive. The combination is expected to create one of the largest independent banks headquartered in Southern California and presents significant prospects for our communities, employees and shareholders. The merger with PCBP, which includes two full-service branches in Orange County, is a logical step in our strategy to achieve critical mass by expanding in local and adjacent markets with attractive demographics and to continue to build franchise value for our new and current shareholders.”

“Premier Commercial Bank has a history of strong credit quality and a tradition of relationship banking which will combine well with California United Bank’s commitment to these same values,” concluded Rainer.

“We believe this is a considerable opportunity for our customers and employees and offers our shareholders not only an excellent value but provides them with the ability to participate in the long-term growth opportunity of our combined franchise,” commented Kenneth Cosgrove, Chairman and Chief Executive Officer of Premier Commercial Bancorp and Premier Commercial Bank, N.A. “The capabilities of a larger institution will enable us to better penetrate our markets and expand our menu of services. California United Bank has built a strong franchise and we look forward to being a part of its future. I am pleased to be continuing on the Board of Directors of the combined company after the merger.”

The merger will be immediately preceded by the formation of CU Bancorp as a bank holding company for California United Bank. Premier Commercial Bank will be merged with and into California United Bank, with California United Bank and its California state banking charter surviving.

Premier Commercial Bancorp shareholders will receive 3,721,442 shares of CU Bancorp Stock which approximates a one for one exchange of shares. The value of California United Bank stock as of December 8, 2011 was $10.25 per share. Adjustment of the number of shares will occur upon certain changes in the market value of California United Bank stock. The receipt of CU Bancorp stock by shareholders of Premier Commercial Bancorp is expected to be structured as a tax-free exchange.

Both banks have been active in their communities with philanthropic activities. Among the charities they support are: The Boys and Girls Club of the West Valley, Casa Pacifica, Carousel Ranch, St. Joseph Hospital Foundation, Semper Fi Fund, Boys and Girls Club of Stanton and the Cystic Fibrosis Foundation. Both banks have received the coveted “Outstanding” rating from their bank regulators for performance under the Community Reinvestment Act (CRA).

No Shareholder shall commit or agree to take any action inconsistent with the foregoing.

(d) Notwithstanding the foregoing, nothing in this Agreement shall limit or restrict and Shareholder from (i) acting in his or her capacity as a director or officer of CUNB or CUB, to the extent applicable, it being understood that this Agreement shall apply to each Shareholder solely in his or her capacity as a shareholder of CUNB or CUB, or (ii) voting in his or her sole discretion on any matter other than those matters referred to in Sections 2(a) or 2(b).

3. Representations, Warranties and Covenants of Shareholder. Each Shareholder hereby represents, warrants and covenants to PCBP and PCB as follows:

(b) Until the Expiration Date, each Shareholder, in the Shareholder’s capacity as a shareholder of CUNB or CUB, will not (and will use such Shareholder’s reasonable best efforts to cause its affiliates, officers, directors and employees and any investment banker, attorney, accountant or other agent retained by such Shareholder or CUNB or CUB, not to): (i) initiate or solicit, directly or indirectly, any proposal, plan or offer to acquire all or any material part of the business or properties or capital stock of CUNB or CUB, whether by merger, purchase of assets, tender offer or otherwise, or to liquidate CUNB or CUB or otherwise distribute to the shareholders of CUNB or CUB all or any substantial part of the business, properties or capital stock of CUNB or CUB (each, an “Acquisition Proposal”); (ii) initiate, directly or indirectly, any contact with any person in an effort to or with a view towards soliciting any Acquisition Proposal; (iii) furnish information concerning CUNB or CUB’s business, properties or assets to any corporation, partnership, person or other entity or group (other than PCB or PCBP, or any affiliate, associate, agent or representative of PCBP or PCB) under any

circumstances that could reasonably be expected to relate to an actual or potential Acquisition Proposal; (iv) negotiate or enter into discussions or an agreement, directly or indirectly, with any entity or group with respect to any potential Acquisition Proposal; or (v) either alone or together with any other shareholder of CUNB or CUB, request that a special meeting of the shareholders of CUNB or CUB be held to consider and vote on any Acquisition Proposal. In the event any Shareholder, in such Shareholder’s capacity as a shareholder of CUNB or CUB, shall receive or become aware of any Acquisition Proposal subsequent to the date hereof, such Shareholder shall promptly inform PCB or PCBP as to any such matter and the details thereof to the extent possible without breaching any other agreement to which such Shareholder is a party.

(c) Each Shareholder understands and agrees that if any Shareholder attempts to vote or provide any other person with the authority to vote any of the Shares held by such Shareholder as of the record date for any meeting at which such Shares are to be voted other than in compliance with this Agreement, CUNB or CUB shall not, and such Shareholder hereby unconditionally and irrevocably instructs CUNB or CUB to not, record such vote unless and until such Shareholder shall have complied with the terms of this Agreement.

5. No Limitation on Discretion as Director. If a Shareholder is a natural person and is a member of CUNB or CUB’s Board, then this Agreement will apply to the exercise by such Shareholder in his or her individual capacity as to rights attaching to the ownership of the Shares, and nothing herein shall be deemed to apply to, or to limit in any manner, the discretion of such Shareholder with respect to any action which may be taken or omitted by him or her, acting in his or her fiduciary capacity as member of such Board.

6. Additional Documents. Each Shareholder hereby covenants and agrees to execute and deliver any additional documents necessary or desirable, in the reasonable opinion of PCB or PCBP, to carry out the purpose and intent of this Agreement. At PCB or PCBP’s request each Shareholder and his spouse or other joint holder of the Shares will execute an irrevocable proxy providing PCB or PCBP with the ability and right to vote the Shareholder’s Shares at any meeting of the shareholders of CUNB or CUB or in connection with any solicitation of shareholder votes by CUNB or CUB by written consent.

7. Consent and Waiver. Each Shareholder hereby consents to and approves the actions taken by the board of directors of CUNB or CUB in approving the Merger and adopting the Merger Agreement and gives any consents or waivers that are reasonably required for the consummation of the Merger under the terms of any agreement to which such Shareholder is a party; provided, however, that such Shareholder shall not be required by this Section 6 to give any consent or waiver in his or her capacity as a director or officer of CUNB or CUB.

8. Termination. This Agreement and the proxy granted in connection herewith shall terminate and shall have no further force or effect as of the Expiration Date.

10. Obligations Attach to Shares; Survival; Acquisition of Additional Shares of Capital Stock of CUNB or CUB. Each Shareholder agrees that this Agreement and the obligations hereunder shall attach to such Shareholder’s Shares and shall be binding upon any person to which or whom legal or beneficial ownership of such Shares shall pass, whether by operation of law or otherwise, including such Shareholder’s heirs, guardians, administrators or successors, and that the transfer agent for the Shares shall be instructed not to record any transfer in violation of the terms of the Agreement. All authority herein conferred by a Shareholder shall survive the death or incapacity of such Shareholder and any obligation of a Shareholder hereunder shall be binding upon the heirs, guardians, administrators, personal representatives, successors and assigns of a Shareholder. In the event of any stock split, stock dividend, merger, reorganization, recapitalization or other change in the capital structure of CUNB or CUB affecting the Shares, or the acquisition of additional shares of capital stock of CUNB or CUB by any Shareholder, the number of shares of capital stock of CUNB or CUB listed under the heading “Total Number of Shares of CUNB or CUB Capital Stock Subject to this Agreement” shall be adjusted appropriately and this Agreement and the obligations hereunder shall attach to any additional shares of capital stock of CUNB or CUB issued to or acquired by such Shareholder.

(b) Binding Effect and Assignment.
