“Per Share Merger Consideration” shall be the amount of the Merger Consideration divided by the total number of shares of PGB Common Stock outstanding immediately prior to the Effective Time (including Appraisal Rights Shares).

(ii)At the Effective Time, each share of PGB Common Stock (except for Appraisal Rights Shares) shall, by virtue of the PGB Merger and without any action on the part of the holder thereof, be cancelled and converted into the right to receive in cash the Per Share Merger Consideration and the holders of certificates formerly representing shares of PGB Common Stock shall cease to have any rights as PGB stockholders. Except as provided above, until such certificates are surrendered for exchange, the certificates of each holder shall, after the Effective Time, represent for all purposes only the right to receive the Per Share Merger Consideration.

(iii)RBB Bancorp shall set aside from the Merger Consideration an amount of cash equal to the Dissenters’ Set Aside. RBB Bancorp shall deliver to the Exchange Agent the remaining cash.

(b)Stock Transfer Books and Exchange. At the Effective Time, the stock transfer books of PGB shall be closed as to holders of PGB Common Stock immediately prior to the Effective Time and no transfer of PGB Common Stock by any such holder shall thereafter be made or recognized on the stock transfer books of PGB as the Resulting Corporation. If, after the Effective Time, certificates are properly presented in accordance with Article III of this Agreement to the Exchange Agent, such certificates shall be canceled and exchanged for a check representing the amount of cash into which the PGB Common Stock represented thereby was converted in the PGB Merger, plus any payment for a fractional share of PGB Common Stock.

(c)Calculations. Within five (5) Business Days after the Calculation Date, PGB shall provide to RBB Bancorp (i) PGB’s unaudited financial statements as of the Calculation Date, (ii) a Certificate of PGB’s chief financial officer as to the accuracy of such financial statements, and confirming that, except as set forth in the Certificate, PGB and the Bank are not aware that such financial statements require any material modifications in order to comply with GAAP or the terms of this Agreement, including regulatory guidelines and requirements with respect to loan and OREO classifications, appraisals and the adequacy of the Bank-ALLL as of such date, and (iii) any additional information reasonably requested by RBB Bancorp. Within five (5) Business Days after receipt by RBB Bancorp of the information described in the previous sentence, RBB Bancorp shall provide PGB with a calculation of the PGB Tangible Book Value, the PGB Transaction Expenses and the components thereof, the Bank-ALLL Adjustment Amount, and the Merger Consideration (“PGB Closing Statement”). RBB Bancorp, RBB, PGB and the Bank shall be allowed to completely review the financial statements and all elements of the PGB Closing Statement without any limitations, including such calculations with respect thereto, the supporting Certificate, and access to any and all supporting books, records, work papers, documents and personnel. All calculations pursuant to this Agreement shall be rounded to the nearest cent.

(d)Dispute Resolution. PGB and the Bank shall have up to five (5) Business Days after receipt of the PGB Closing Statement to review the PGB Closing Statement as calculated by RBB Bancorp. If PGB and the Bank disagree with the PGB Closing Statement, PGB and the Bank shall notify RBB Bancorp in writing, and PGB and the Bank shall provide reasonable detail of the nature of each disputed item on the PGB Closing Statement, including all supporting documentation thereto. The parties shall first use commercially reasonable and good faith efforts to resolve such dispute between themselves and make such revisions to the PGB Closing Statement as necessary to reflect such resolution. If the parties are unable to resolve such dispute within two (2) Business Days, the parties shall submit the dispute to a nationally recognized accounting firm mutually acceptable to RBB Bancorp and PGB (the “Accounting Firm”) for a resolution of any issue that is in dispute, and the resolution of the Accounting Firm shall be binding on all parties. The parties shall each pay one-half (1/2) of the fees and costs of the Accounting Firm and the fees paid to the Accounting Firm by PGB and/or the Bank shall be deducted from the PGB Tangible Book Value. The parties agree that they will, and agree to cause their respective representatives and independent accountants to, cooperate and assist in the preparation of the PGB Closing Statement and in the conduct of the audits and review referred to in this Section 3.03(d) including, without limitation, making available books, records, work papers and personnel as shall be necessary to attempt to resolve the dispute.

(a)Exchange Agent. No later than the Effective Time, RBB Bancorp shall deposit with the Exchange Agent cash in an amount equal to the Merger Consideration (the “Exchange Fund”).

(b)Exchange of Certificates and Cash. Each holder of a certificate formerly representing PGB Common Stock (other than Appraisal Rights Shares) who surrenders or has surrendered such certificate (or customary affidavits and indemnification regarding the loss or destruction of such certificate), together with duly executed transmittal materials, to the Exchange Agent shall, upon acceptance thereof, be entitled to cash into which the shares of PGB Common Stock shall have been converted pursuant hereto. The Exchange Agent shall accept such PGB certificate upon compliance with such reasonable and customary terms and conditions as the Exchange Agent may impose to cause an orderly exchange thereof in accordance with normal

practices. PGB shall be afforded an opportunity to consent to the Exchange Agent agreement and the form of transmittal materials before they are mailed, which consents shall not be unreasonably withheld. RBB Bancorp shall not be obligated to deliver the consideration to which any former holder of PGB Common Stock is entitled as a result of the PGB Merger until such holder surrenders a certificate or certificates representing such shares of PGB Common Stock for exchange as provided herein, or an affidavit of lost stock certificate.

(c)No Liability. Notwithstanding the foregoing, neither the Exchange Agent nor any party hereto shall be liable to any former holder of PGB Common Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

(d)PGB Common Stock. Until surrendered for exchange in accordance with the provisions of this Section 3.04, each certificate previously representing shares of PGB Common Stock (other than Appraisal Rights Shares) shall from and after the Effective Time represent for all purposes only the right to receive the Per Share Merger Consideration, as set forth in this Agreement.

(e)Withholding Rights. RBB Bancorp or the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of PGB Common Stock such amounts as RBB Bancorp or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign tax law. To the extent that amounts are so withheld and paid over to the appropriate taxing authority by RBB Bancorp or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of PGB Common Stock in respect of which such deduction and withholding was made by RBB Bancorp or the Exchange Agent.

(f)Six Month Anniversary. At any time following the six-month anniversary of the Effective Time, RBB Bancorp shall be entitled to require the Exchange Agent to deliver to it any remaining portion of the Exchange Fund not distributed to holders of shares of PGB Common Stock that was deposited with the Exchange Agent at the Effective Time (including any interest received with respect thereto and other income resulting from investments by the Exchange Agent, as directed by RBB Bancorp), and such holders shall be entitled to look only to RBB Bancorp (subject to abandoned property, escheat or other similar laws) with respect to the Merger Consideration, without any interest thereon. Notwithstanding the foregoing, neither RBB Bancorp nor the Exchange Agent shall be liable to any holder of a PGB Stock Certificate entitled to receive the Merger Consideration (or dividends or distributions with respect thereto), or cash from the Exchange Fund in each case delivered to a public official pursuant to any applicable abandoned property, escheat or similar laws.

(g)Lost, Stolen or Destroyed Certificates. In the event any certificate of PGB Common Stock shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such certificate(s) of PGB Common Stock to be lost, stolen or destroyed, and if required by RBB Bancorp or the Exchange Agent, the posting by such Person of a bond in such sum as RBB Bancorp may reasonably direct as indemnity against any claim that may be made against it or the Resulting Corporation with respect to such certificate(s) of PGB Common Stock, RBB Bancorp shall cause the Exchange Agent to issue the Merger Consideration deliverable in respect of the shares of PGB Common Stock represented by such lost, stolen or destroyed certificates of PGB Common Stock.

(a)Any Appraisal Rights Shareholder that shall be entitled to be paid the value of such shareholder’s shares of PGB Common Stock as provided in Section 262 of the DGCL, shall not be entitled to the Per Share Merger Consideration in respect thereof provided for under Section 3.03, unless and until such Appraisal Rights Shareholder shall have failed to perfect or shall have effectively withdrawn or lost such Appraisal Rights Shareholder under Section 262 of the DGCL, and shall be entitled to receive only the payment provided for by DGCL Section 262 with respect to the Appraisal Rights Shares.

(b)If any Appraisal Rights Shareholder shall fail to perfect or shall have effectively withdrawn or lost such right to dissent, each share of PGB Common Stock of such Appraisal Rights Shareholder shall be converted into the right to receive the Per Share Merger Consideration.

(c)PGB shall give RBB Bancorp prompt notice upon receipt by PGB of any written demands by Appraisal Rights Shareholders, withdrawal of such demands, and any other documents received or instruments served relating to Appraisal Rights Shareholders and shall give RBB Bancorp the opportunity to direct all negotiations and proceedings with respect to such demands. PGB shall not voluntarily make any payment with respect to any demands by Appraisal Rights Shareholders and shall not, except with the prior written consent of RBB Bancorp, settle or offer to settle such demands. Each Appraisal Rights Shareholder who becomes entitled to payment for his or her Appraisal Rights shall receive payment therefore from RBB Bancorp, and such Appraisal Rights Shares shall be canceled.

Notwithstanding the foregoing, nothing herein shall prevent the parties hereto from any general advertising or recruitment activities not directed specifically at the employees of the other party hereto.

PGB or the Bank further agree that they shall not, and that they shall direct and use their reasonable best efforts to cause their directors, officers, employees, agents and representatives not to, directly or indirectly, engage in any negotiations concerning, or provide any confidential information or data to, or have any discussions with, any Person relating to an Acquisition Proposal, or otherwise facilitate any effort or attempt to make or implement an Acquisition Proposal; provided, however, that nothing contained in this Agreement shall prevent PGB and the Bank, or the PGB Board or the Bank Board, from (A) complying with its disclosure obligations under federal or state law; (B) providing information in response to a request therefor by a Person

An Acquisition Proposal which is received and considered by PGB or the Bank in compliance with this Section 6.06 and which meets the requirements set forth in (i) and (ii) above of the preceding sentence is herein referred to as a “Superior Proposal.” PGB and the Bank agree that they will immediately cease and cause to be terminated any existing activities, discussions or negotiations with any parties conducted heretofore with respect to any Acquisition Proposals.

In rendering its opinion, RSM US LLP may require and rely upon representations contained in letters from RBB Bancorp, RBB, PGB or the Bank and/or their officers or principal shareholders as are customary for such opinions, and all parties to this agreement shall cooperate by providing the representations required by RSM US LLP.

(b)In the event that (i) a bona fide Acquisition Proposal shall have been made to PGB or the Bank or any of its shareholders or any Person shall have publicly announced an intention (whether or not conditional) to make an Acquisition Proposal with respect to PGB or the Bank (and such Acquisition Proposal or publicly announced intention shall not have been publicly withdrawn without qualification at least (x) 30 calendar days prior to, with respect to any termination pursuant to Section 8.01(c) or Section 8.01(d), the date of termination, or (y) at least 10 Business Days prior to, with respect to a termination pursuant to Section 8.01(f), the date of the Special Meeting); and thereafter this Agreement is terminated by either RBB Bancorp and RBB or PGB and the Bank pursuant to Section 8.01(d), or (ii) this Agreement is terminated (x) by PGB and the Bank pursuant to Section 8.01(g) or (y) by RBB Bancorp and RBB pursuant to Section 8.01(b), (c) or (f), then PGB or the Bank shall promptly, and in any event no later than two Business Days after the date of such

termination (except as provided in Section 8.01(g)(iv)), pay RBB Bancorp a termination fee of $500,000 (the “Termination Fee”), payable by wire transfer of same-day funds.

In addition, for purposes of this Agreement, and subject to proviso (i) of Section 8.02(a), no damages will be payable by RBB Bancorp if it terminates this Agreement for failure to obtain regulatory approval pursuant to Section 7.01(b) or Section 8.01(e).

RBB’s payment shall be the sole and exclusive remedy of PGB and the Bank for damages against RBB and their respective Representatives with respect to the breach of any covenant or agreement giving rise to such payment other than for fraud.

Each of PGB and the Bank, and RBB Bancorp and RBB, acknowledge that the agreement contained in Section 8.02(b) is an integral part of the transactions contemplated by this Agreement and that without the agreement, RBB Bancorp, RBB, PGB and the Bank would not enter into this Agreement; accordingly, if PGB or the Bank fails to pay the Termination Fee pursuant to Section 8.02(b), and RBB Bancorp and RBB commence a suit in order to obtain payment of the Termination Fee and that results in a judgment against PGB or the Bank for the Termination Fee, then PGB or the Bank shall pay to RBB Bancorp and RBB their costs and expenses (including attorneys’ fees and expenses) in connection with such suit, together with interest on the amount of such fee at the publicly announced prime rate of interest published in The Wall Street Journal on the date such payment was required to be made from the date such payment was required to be made through the date of payment, provided, however, that if RBB Bancorp and RBB commence a suit in which they fail to obtain a judgment against PBG or the Bank for the Termination Fee, then RBB Bancorp or RBB Bank shall pay to PGB and the Bank the costs and expenses incurred by PGB and the Bank (including attorneys’ fees and expenses) in connection with such suit, together with interest on the amount of such fee at the publicly announced prime rate of interest published in The Wall Street Journal on the date such payment was required to be made from the date such payment was required to be made through the date of payment.

The representations, warranties, agreements and covenants contained in this Agreement shall not survive the Effective Time (other than Sections 6.05, 6.09, 6.10, 6.11, 6.15, 6.18, and this Article IX, which shall survive the Effective Time indefinitely unless otherwise specifically provided therein) or the termination of this Agreement if this Agreement is terminated prior to the Effective Time. This Article IX and the covenants contained in Section 8.02 (Effect of Termination and Abandonment) shall survive the termination of this Agreement. All other representations, warranties, covenants and agreements in this Agreement shall not survive the consummation of the PGB Merger or the termination of this Agreement if this Agreement is terminated prior to the Effective Time.

Prior to the Effective Time and subject to applicable provisions of the DGCL, any provision of this Agreement may be (i) waived in whole or in part by the party benefited by the provision or by all parties or (ii) amended or modified at any time, by an agreement in writing among the parties hereto executed in the same manner as this Agreement.

This Agreement may be executed in one or more counterparts, each of which shall be deemed to constitute an original but all of which together shall constitute one and the same instrument. Facsimiles containing original signatures shall be deemed for all purposes to be originally signed copies of documents which are the subject of such facsimiles.

This Agreement shall be governed by, and interpreted in accordance with, the laws of the State of California (however, not to the exclusion of any applicable Federal law), without regard to California statutes or judicial decisions regarding choice of law questions. The parties hereby irrevocably submit to the jurisdiction of the courts of the State of California and the federal courts of the United States of America located in the Southern District of the State of California solely in respect of the interpretation and enforcement of the provisions of this Agreement and of the documents referred to in this Agreement, and in respect of the transactions contemplated herein and therein, and hereby waive, and agree to assert, as a defense in any action, suit or proceeding for the interpretation or enforcement hereof or of any such documents, that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in said courts or that the venue thereof may not be appropriate or that this Agreement or any such document may not be enforced in or by such courts, and the parties hereto irrevocably agree that all claims with respect to such action or proceeding shall be heard and determined in such California state or federal court. The parties hereby consent to and grant any such court jurisdiction over the person of such parties and over the subject matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 9.06 or in such other manner as may be permitted by law, shall be valid and sufficient service thereof.

Each party hereto will bear all expenses incurred by it in connection with this Agreement and the transactions contemplated hereby except as otherwise specifically provided. RBB shall bear all costs associated with obtaining all Regulatory Approvals.

All notices, requests and other communications hereunder to a party shall be in writing and shall be deemed given if personally delivered, by electronic mail (with confirmation) or mailed by registered or certified mail (return receipt requested) to such party at its address set forth below or such other address as such party may specify by notice to the parties hereto.

This Agreement, the Disclosure Schedules attached hereto and incorporated herein, and the exhibits to the Agreement represent the entire understanding of the parties hereto and thereto with reference to the transactions contemplated hereby and thereby and this Agreement, the Disclosure Schedules attached hereto and incorporated herein, and the exhibits to the Agreement, supersede any and all other oral or written agreements heretofore made.

No provision of this Agreement shall be construed to require PGB, the Bank, RBB Bancorp RBB or any Subsidiaries, affiliates or directors of any of them to take any action or omit to take any action which action or omission would violate applicable law (whether statutory or common law), rule or regulation.

Except to the extent that application of this Section 9.09 would have a Material Adverse Effect on PGB and the Bank, or RBB Bancorp and RBB, any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable.

The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. Except as provided in Section 8.02(a), it is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity.
