AGREEMENT AND PLAN OF MERGER

THIS AGREEMENT AND PLAN OF MERGER, dated as of April 23, 2025 (this “Agreement”), is by and among Columbia Banking System, Inc., a Washington corporation (“Parent”), Pacific Premier Bancorp, Inc., a Delaware corporation (the “Company”), and Balboa Merger Sub, Inc., a Delaware corporation and a wholly owned Subsidiary of Parent (“Merger Sub”).

RECITALS

A. The Boards of Directors of Parent, the Company and Merger Sub have determined that it is in the best interests of their respective companies and shareholders and stockholders, as applicable, to consummate the strategic business combination transaction provided for in this Agreement and have approved this Agreement.

B. On the terms and subject to the conditions set forth in this Agreement, Merger Sub will merge with and into the Company (the “Merger”), with the Company as the surviving corporation in the Merger (sometimes hereinafter referred to as the “Surviving Corporation”).

C. Immediately following the Merger and as part of a single integrated transaction, the Surviving Corporation will merge with and into Parent (the “Second Step Merger,” and together with the Merger, the “Mergers”), with Parent as the surviving entity in the Second Step Merger (sometimes hereinafter referred to as the “Surviving Entity”).

D. Promptly following the Second Step Merger, Pacific Premier Bank, National Association, a national banking association and wholly owned Subsidiary of the Company (“Pacific Premier Bank”), will merge with and into Umpqua Bank, an Oregon state-chartered commercial bank and wholly owned Subsidiary of Parent (“Umpqua Bank”), with Umpqua Bank as the surviving bank (the “Bank Merger”).

E. The parties intend that the Merger and the Second Step Merger, taken together, shall be treated as a single integrated transaction and shall qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and that this Agreement shall constitute a “plan of reorganization” for purposes of Sections 354 and 361 of the Code.

F. The parties desire to make certain representations, warranties and agreements in connection with the Merger and also to prescribe certain conditions to the Merger.

NOW, THEREFORE, in consideration of the mutual covenants, representations, warranties and agreements contained in this Agreement, and intending to be legally bound hereby, the parties agree as follows:

ARTICLE 1

MERGERS

1.1 The Merger. Subject to the terms and conditions of this Agreement, in accordance with the Delaware General Corporation Law (the “DGCL”), at the Effective Time, Merger Sub shall merge with and into the Company in the Merger. The Company shall be the Surviving Corporation in the Merger as a wholly owned Subsidiary of Parent and shall continue its existence under the Laws of the State of Delaware. As of the Effective Time, the separate corporate existence of Merger Sub shall cease.

1.2 Closing. On the terms and subject to conditions set forth in this Agreement, the closing of the Merger (the “Closing”) shall take place by electronic exchange of documents at 10:00 a.m., Pacific Time, on (a) the earliest to occur of (i) the first (1^st) Business Day of the first (1^st) calendar month that follows the month in which the last to be satisfied or waived of the conditions set forth in Article 7 is satisfied or waived (such date of satisfaction or waiver, the “Last Condition Satisfaction Date”) (other than those conditions that by their nature are to be satisfied or waived at the Closing but subject to the satisfaction or waiver of those conditions) and (ii) the last Business Day of the calendar quarter in which the Last Condition Satisfaction Date occurs or (b) such other date as mutually agreed in writing by the parties (such date on which the Closing actually occurs, the “Closing Date”).

1.3 Effective Time. Subject to the terms and conditions of this Agreement, on or (if agreed by the Company and Parent) before the Closing Date, the parties will execute and cause a certificate of merger (the “Certificate of Merger”) relating to the Merger to be filed with the Secretary of State of the State of Delaware (“Delaware Secretary”) in accordance with the Section 252(c) of the DGCL. The Merger shall become effective at such time as such Certificate of Merger has been filed, or at such other time as may be specified therein. The term “Effective Time” shall be the date and time when the Merger becomes effective in accordance therewith.

1.4 Effects of the Merger. At and after the Effective Time, the Merger shall have the effects set forth in the applicable provisions of the DGCL.

1.5 Conversion of Stock. At the Effective Time, by virtue of the Merger and without any action on the part of the Company, Merger Sub or Parent or the shareholders or stockholders, as applicable, of any of the foregoing:

(a) Company Common Stock. Each share of Company Common Stock, excluding Treasury Shares, issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive 0.9150 of a share of Parent Common Stock (the “Exchange Ratio”), subject to any adjustments pursuant to Section 1.5(e) (the “Merger Consideration”), and subject to the payment of any cash in lieu of fractional shares pursuant to Section 2.2(f). At the Effective Time, all shares of Company Common Stock shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist.

(b) Cancellation of Treasury Shares. Any shares of Company Common Stock owned by the Company as treasury stock or owned, directly or indirectly, by Parent or the Company or any of their respective wholly owned Subsidiaries (other than those held in a

-2-

fiduciary capacity or as a result of debts previously contracted) (“Treasury Shares”), shall automatically be cancelled and retired and shall cease to exist at the Effective Time, and no consideration shall be issued in exchange therefor.

(c) Outstanding Merger Sub Common Stock. Each share of common stock, par value $0.01 per share, of Merger Sub (the “Merger Sub Common Stock”) issued and outstanding immediately prior to the Effective Time shall be converted into one share of common stock, par value $0.01 per share, of the Surviving Corporation, which shall constitute the only shares of capital stock of the Surviving Corporation.

(d) Effect of Conversion. All of the shares of Company Common Stock converted into the right to receive the Merger Consideration pursuant to this Article 1 shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time, and each certificate previously representing any such shares of Company Common Stock (each, a “Certificate”) and each non-certificated share of Company Common Stock evidenced in book-entry form (“Book-Entry Share”) shall thereafter represent only the right to receive the Merger Consideration and/or cash in lieu of fractional shares, into which the shares of Company Common Stock represented by such Certificate or Book-Entry Share have been converted pursuant to this Section 1.5 and Section 2.2(f), as well as any dividends to which holders of Company Common Stock become entitled in accordance with Section 2.2(c).

(e) Adjustments to Exchange Ratio. If, between the date of this Agreement and the Effective Time, the outstanding shares of Parent Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar change in capitalization, or there shall be any extraordinary dividend or distribution, an appropriate and proportionate adjustment shall be made to the Exchange Ratio to give the Company and the holders of Company Common Stock the same economic effect as contemplated by this Agreement prior to such event; provided, that nothing contained in this sentence shall be construed to permit Parent or the Company to take any action with respect to its securities or otherwise that is otherwise prohibited by the terms of this Agreement.

1.6 Treatment of Company Equity Awards.

(a) At the Effective Time, each award in respect of shares of Company Common Stock subject to vesting, repurchase or other lapse restriction granted or assumed under a Company Stock Plan that is outstanding and unvested immediately prior to the Effective Time (a “Company RSA”) shall (i) if granted to a non-employee member of the Board of Directors of the Company (the “Company Board”), be converted into the right to receive shares of Parent Common Stock in accordance with Section 1.5(a), less applicable withholding and (ii) if not granted to an individual described in clause (i), be assumed and converted into a restricted stock award in respect of Parent Common Stock (a “Parent RSA”) with the same terms and conditions as were applicable under such Company RSA immediately prior to the Effective Time (including vesting terms and any change in control and termination of employment protection under the Company Stock Plans and Company RSA award agreements) and relating to a number of shares of Parent Common Stock equal to (A) the number of shares of Company Common Stock subject

-3-

to such Company RSA immediately prior to the Effective Time, multiplied by (B) the Exchange Ratio, with any fractional shares rounded to the nearest whole share of Parent Common Stock. Any dividends that were accrued (but not paid) on such Company RSA immediately prior to the Effective Time shall be paid to the applicable holder (x) in the case of a Company RSA granted to a non-employee member of the Company Board, promptly after the Effective Time and (y) in the case of a Company RSA not granted to a non-employee member of the Company Board, at the time the converted Parent RSA becomes vested in accordance with its terms.

(b) At the Effective Time, each performance-based restricted stock unit award in respect of shares of Company Common Stock granted under a Company Stock Plan that is outstanding, unvested and unsettled immediately prior to the Effective Time (a “Company PSU”) shall be assumed and converted automatically into a restricted stock unit in respect of Parent Common Stock (an “Adjusted PSU”) relating to the number of shares of Parent Common Stock equal to the product of (i) the number of shares of Company Common Stock subject to such Company PSU immediately prior to the Effective Time that would be earned assuming the achievement of the applicable performance goals as of immediately prior to the Effective Time based on target performance (which amount shall include without limitation or duplication any shares of Company Common Stock issuable in respect of dividend equivalents accrued as of immediately prior to the Effective Time on such number of shares of Company Common Stock), multiplied by (ii) the Exchange Ratio, with any fractional shares rounded to the nearest whole share of Parent Common Stock. Except as specifically provided in this Section 1.6(b), each such Adjusted PSU shall be subject to the same terms and conditions (including vesting terms and any change in control and termination of employment protection under the Company Stock Plans and Company PSU award agreements) as applied to the Company PSU immediately prior to the Effective Time, subject to each holder of a Company PSU, prior to the Effective Time, delivering to the Company a duly executed and properly completed acknowledgement in the form to be agreed between Parent and the Company; provided, that each such Adjusted PSU shall be subject only to service-based vesting through the end of the original performance period under the applicable Company PSU and shall no longer be subject to any performance conditions.

(c) At the Effective Time, each option granted by the Company to purchase shares of Company Common Stock under a Company Stock Plan that is outstanding and unexercised immediately prior to the Effective Time (a “Company Stock Option Award”), whether vested or unvested, shall be cancelled and entitle the holder of such Company Stock Option Award to receive, no later than the second payroll date after the Effective Time, an amount in cash equal to the product (rounded up to the nearest whole cent) of (i) the number of shares of Company Common Stock subject to such Company Stock Option Award immediately prior to the Effective Time, multiplied by (ii) the excess, if any, of (1) the Company Stock Option Award Cashout Price over (2) the exercise price per share of Company Common Stock subject to such Company Stock Option Award immediately prior to the Effective Time, less applicable Taxes required to be withheld with respect to such payment. For the avoidance of doubt, any Company Stock Option Award which has an exercise price per share of Company Common Stock that is greater than or equal to the Company Stock Option Award Cashout Price shall be cancelled at the Effective Time for no consideration or payment, subject to each holder of each such Company Stock Option Award, prior to the Effective Time, delivering to the Company a duly executed and properly completed acknowledgement in the form to be agreed between Parent and the Company.

-4-

(d) Promptly following the Effective Time, Parent shall file a post-effective amendment to the Form S-4 or an effective registration statement on Form S-8 with respect to the Parent Common Stock subject to the applicable adjusted Company Equity Awards, as required under the Securities Act.

(e) At or prior to the Effective Time, the Company, the Company Board or the Compensation Committee of the Company Board, as applicable, shall adopt any resolutions and take any actions that are necessary to effectuate the treatment of the Company Equity Awards consistent with the provisions of this Section 1.6.

(f) For purposes of this Agreement, the following terms shall have the following meanings:

(i) “Company Equity Awards” means the Company RSAs, the Company PSUs and the Company Stock Option Awards.

(ii) “Company Stock Plans” means the Heritage Oaks Bancorp, Inc. 2015 Equity Based Compensation Plan and the Pacific Premier Bancorp, Inc. Amended and Restated 2022 Long-Term Incentive Plan.

(iii) “Company Stock Option Award Cashout Price” means an amount in cash equal to the product of (A) the Exchange Ratio, multiplied by (B) the average of the per share closing price of Parent Common Stock for the consecutive period of five (5) full trading days ending on the day that is five (5) days preceding the Closing Date.

1.7 Certificate of Incorporation and Bylaws. At the Effective Time, the Certificate of Incorporation of Merger Sub, as then in effect, will be the Certificate of Incorporation of the Surviving Corporation, and the Bylaws of Merger Sub, as then in effect, will be the Bylaws of the Surviving Corporation.

1.8 Merger Sub Board Directors and Officers. The directors of Merger Sub in office immediately prior to the Effective Time shall serve as the directors of the Surviving Corporation from and after the Effective Time in accordance with the Bylaws of the Surviving Corporation. The officers of Merger Sub in office immediately prior to the Effective Time shall serve as the officers of the Surviving Corporation from and after the Effective Time in accordance with the Bylaws of the Surviving Corporation. The parties shall take all actions necessary to effect the provisions of this Section 1.8.

1.9 Second Step Merger.

(a) Immediately following the Effective Time, in accordance with the Washington Business Corporation Act (the “WBCA”) and the DGCL, Parent shall cause the Surviving Corporation to be merged with and into Parent in the Second Step Merger, with Parent surviving the Second Step Merger as the Surviving Entity and continuing its existence under the laws of the State of Washington, and the separate corporate existence of the Surviving

Corporation ceasing as of the Second Effective Time. In furtherance of the foregoing, Parent shall cause to be filed with the Secretary of State of the State of Washington (the “Washington Secretary”), in accordance with the WBCA, articles of merger (the “Second Step Articles of Merger”) relating to the Second Step Merger and shall cause to be filed with the Delaware Secretary, in accordance with the DGCL, a certificate of merger relating to the Second Step Merger (the “Second Step Certificate of Merger”). The Second Step Merger shall become effective at such time specified in the Second Step Articles of Merger and the Second Step Certificate of Merger in accordance with the relevant provisions of the WBCA and the DGCL (such time hereinafter referred to as the “Second Effective Time”).

(b) At the Second Effective Time, by virtue of the Second Step Merger and without any action on the part of Parent or the Surviving Corporation, each share of common stock, par value $0.01 per share, of the Surviving Corporation shall be cancelled and shall cease to exist, and no consideration shall be delivered in exchange therefor.

(c) At and after the Second Effective Time, each share of Parent Common Stock issued and outstanding immediately prior to the Second Effective Time shall remain an issued and outstanding share of Parent Common Stock and shall not be affected by the Second Step Merger; it being understood that upon the Second Effective Time, the Parent Common Stock, including the shares issued to former holders of Company Common Stock, shall be the common stock of the Surviving Entity.

(d) At the Second Effective Time, the Restated Articles of Incorporation of Parent (the “Parent Articles”) shall be the Articles of Incorporation of the Surviving Entity until thereafter amended in accordance with applicable Law.

(e) At the Second Effective Time, the Bylaws of Parent (the “Parent Bylaws”) shall be the Bylaws of the Surviving Entity until thereafter amended in accordance with applicable Law.

(f) At the Second Effective Time, the officers and directors of Parent as of immediately following the Effective Time (including, for the avoidance of doubt, with respect to the appointment of the Company Designated Directors to the Parent Board as provided in Section 6.19) shall be the officers and directors of the Surviving Entity.

Each of Parent and the Company shall approve the Bank Merger Agreement and the Bank Merger as the sole shareholder of Umpqua Bank and Pacific Premier Bank, respectively, and Parent and the Company shall execute and cause to be filed applicable articles or certificates of merger and such other documents as are necessary to make the Bank Merger effective promptly following the Second Effective Time. The Bank Merger shall become effective at such time and date as specified in the Bank Merger Agreement in accordance with applicable Law, or at such other time as shall be provided by applicable Law.

ARTICLE 2

DELIVERY OF MERGER CONSIDERATION

2.1 Delivery of Merger Consideration. At or prior to the Effective Time, Parent shall deposit, or cause to be deposited, with an exchange agent selected by Parent and reasonably acceptable to the Company (the “Exchange Agent”), pursuant to an agreement (the “Exchange Agent Agreement”) entered into prior to the Effective Time, (a) shares of Parent Common Stock issuable pursuant to Section 1.5(a), plus (b) to the extent then determinable, any cash payable in lieu of fractional shares pursuant to Section 2.2(f) (such amount in cash and Parent Common Stock, the “Exchange Fund”).

2.2 Exchange Procedures.

(a) As soon as reasonably practicable after the Effective Time, but in any event within five (5) Business Days thereafter, Parent shall cause the Exchange Agent to mail to each holder of record of Certificate(s) or Book-Entry Shares which, immediately prior to the Effective Time, represented outstanding shares of Company Common Stock whose shares were converted into the right to receive the Merger Consideration pursuant to Article 1 (“Exchanged Shares”), along with, in each case, any cash in lieu of fractional shares of Parent Common Stock to be issued or paid in consideration therefor, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to Certificate(s) or Book-Entry Shares shall pass, only upon delivery of Certificate(s) (or affidavits of loss in lieu of such Certificate(s)) or Book-Entry Shares to the Exchange Agent and shall be substantially in such form and have such other provisions as shall be prescribed by the Exchange Agent Agreement (the “Letter of Transmittal”)) and (ii) instructions for use in surrendering Certificate(s) or Book-Entry Shares in exchange for the Merger Consideration, any cash in lieu of fractional shares of Parent Common Stock to be issued or paid in consideration therefor and any dividends or distributions to which such holder is entitled pursuant to Section 2.2(c).

(b) Upon surrender to the Exchange Agent of its Certificate(s) or Book-Entry Share(s) accompanied by a properly completed Letter of Transmittal, a holder of Exchanged Shares will be entitled to receive promptly, after such surrender, (i) the Merger Consideration and any cash in lieu of fractional shares of Parent Common Stock to be issued or paid in consideration therefor in respect of the Exchanged Shares represented by its Certificate(s) or Book-Entry Shares and (ii) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2(c). Until so surrendered, each such Certificate or Book-Entry Share shall represent after the Effective Time, for all purposes, only the right to receive, without interest, the Merger Consideration and any cash in lieu of fractional shares of Parent Common Stock to be issued or paid in consideration therefor upon surrender of such Certificate or Book-Entry Share, in accordance with, and any dividends or distributions to which such holder is entitled pursuant to, this Article 2.

-7-

(c) No dividends or other distributions with respect to Parent Common Stock shall be paid to the holder of any unsurrendered Certificate or Book-Entry Shares with respect to the shares of Parent Common Stock represented thereby, in each case unless and until the surrender of such Certificate or Book-Entry Share in accordance with this Article 2. Following surrender of any such Certificate or Book-Entry Share in accordance with this Article 2, the record holder thereof shall be entitled to receive, without interest, (i) the amount of dividends or other distributions with a record date after the Effective Time theretofore payable with respect to the whole shares of Parent Common Stock represented by such Certificate or Book-Entry Share and paid prior to such surrender date, and/or (ii) at the appropriate payment date, the amount of dividends or other distributions payable with respect to shares of Parent Common Stock represented by such Certificate or Book-Entry Shares with a record date after the Effective Time (but before such surrender date) and with a payment date subsequent to the issuance of the Parent Common Stock issuable with respect to such Certificate or Book-Entry Shares.

(d) In the event of a transfer of ownership of a Certificate or Book-Entry Shares representing Exchanged Shares that are not registered in the stock transfer records of the Company, the shares of Parent Common Stock plus any cash in lieu of fractional shares of Parent Common Stock comprising the Merger Consideration shall be issued or paid in exchange therefor to a Person other than the Person in whose name the Certificate or Book-Entry Shares so surrendered is registered if the Certificate or Book-Entry Shares formerly representing such Exchanged Shares shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment or issuance shall pay any transfer or other similar taxes required by reason of the payment or issuance to a Person other than the registered holder of the Certificate or Book-Entry Shares, or establish to the reasonable satisfaction of the Exchange Agent that the tax has been paid or is not applicable. The Exchange Agent (or, subsequent to the earlier of (x) the one (1)-year anniversary of the Effective Time and (y) the expiration or termination of the Exchange Agent Agreement, Parent) shall be entitled to deduct and withhold from any cash otherwise payable pursuant to this Agreement to any holder of Exchanged Shares such amounts as the Exchange Agent or Parent, as the case may be, is required to deduct and withhold under the Code, or any provision of state, local or foreign Tax Law, with respect to the making of such payment. If, prior to the Closing Date, the Exchange Agent or Parent determines that any such deduction or withholding is so required as of the Effective Time, the Exchange Agent or Parent, as the case may be, shall notify the Company, and the parties shall cooperate in good faith to reduce or eliminate such deduction or withholding. To the extent the amounts are so withheld by the Exchange Agent or Parent, as the case may be, and timely paid over to the appropriate Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Exchanged Shares in respect of whom such deduction and withholding was made by the Exchange Agent or Parent, as the case may be.

(e) After the Effective Time, there shall be no transfers on the stock transfer books of the Company of the shares of Company Common Stock that were issued and outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates or Book-Entry Shares representing any such shares of Company Common Stock are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for the applicable Merger Consideration and any cash in lieu of fractional shares of Parent Common Stock to be issued or paid in consideration therefor in accordance with the procedures set forth in this Article 2.

-8-

(f) Notwithstanding anything to the contrary contained in this Agreement, no fractional shares of Parent Common Stock shall be issued upon the surrender of Certificates or Book-Entry Shares for exchange, no dividend or distribution with respect to Parent Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of Parent. In lieu of the issuance of any such fractional share, Parent shall pay to each former holder of Company Common Stock who otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest cent) determined by multiplying (i) the average of the closing-sale prices of Parent Common Stock on the Nasdaq Global Select Market (“Nasdaq”) as reported by The Wall Street Journal for the consecutive period of five (5) full trading days ending on the day preceding the Closing Date by (ii) the fraction of a share (after taking into account all shares of Company Common Stock held by such holder immediately prior to the Effective Time and rounded to the nearest thousandth when expressed in decimal form) of Parent Common Stock to which such holder would otherwise be entitled to receive pursuant to Section 1.5.

(g) Any portion of the Exchange Fund that remains unclaimed by the stockholders of the Company as of the one (1)-year anniversary of the Effective Time will be paid to the Surviving Entity. In such event, any former holders of Company Common Stock who have not theretofore complied with this Article 2 shall thereafter look only to the Surviving Entity with respect to payment of the shares of Company Common Stock, any cash in lieu of any fractional shares, and any unpaid dividends and distributions on the Parent Common Stock deliverable in respect of each former share of Company Common Stock such holder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of Parent, the Company, the Surviving Entity, the Exchange Agent or any other Person shall be liable to any former holder of shares of Company Common Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar Laws.

(h) In the event that any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if reasonably required by Parent or the Exchange Agent, the posting by such Person of a bond in such amount as Parent may reasonably determine is necessary as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate, the applicable Merger Consideration and any cash in lieu of fractional shares of Parent Common Stock to be issued or paid in consideration therefor in accordance with the procedures set forth in this Article 2 deliverable in respect thereof pursuant to this Agreement.

ARTICLE 3

REPRESENTATIONS AND WARRANTIES OF THE COMPANY

Except (a) as disclosed in the disclosure schedule delivered by the Company to Parent concurrently herewith (the “Company Disclosure Schedule”); provided, that (i) no such item is required to be set forth as an exception to a representation or warranty if its absence would not result in the related representation or warranty being deemed untrue or incorrect, (ii) the mere inclusion of an item in the Company Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission by the Company that such item represents a material exception or fact, event or circumstance or that such item would reasonably

-9-

be expected to result in a Material Adverse Effect, and (iii) any disclosures made with respect to a section of this Article 3 shall be deemed to qualify (1) any other section of this Article 3 specifically referenced or cross-referenced and (2) other sections of this Article 3 to the extent it is reasonably apparent on its face (notwithstanding the absence of a specific cross-reference) from a reading of the disclosure that such disclosure applies to such other sections or (b) as disclosed in any Company SEC Reports filed by the Company after January 1, 2023 and prior to the date hereof (but disregarding risk factor disclosures contained under the heading “Risk Factors,” or disclosures of risks set forth in any “forward-looking statements” disclaimer or any other statements that are similarly nonspecific or cautionary, predictive or forward-looking in nature), the Company hereby represents and warrants to Parent as follows:

3.1 Corporate Organization.

(a) The Company is a corporation duly incorporated, validly existing and in good standing under the Laws of the State of Delaware. The Company has the requisite corporate power and authority to own or lease all of its properties and assets and to carry on its business as it is now being conducted and is duly licensed or qualified to do business in each jurisdiction in which the nature of the business conducted by it, or the character or location of the properties and assets owned or leased by it, makes such licensing or qualification necessary, except where the failure to be so licensed or qualified or to be in good standing would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on the Company. The Company is duly registered as a bank holding company under the Bank Holding Company Act of 1956, as amended (“BHC Act”). As used in this Agreement, the term “Material Adverse Effect” means, with respect to any of the Company, Parent or the Surviving Entity, as the case may be, any effect, change, event, circumstance, condition, occurrence or development that, either individually or in the aggregate, has had or would reasonably be expected to have a material adverse effect on (a) the business, assets, liabilities, properties, financial condition, or results of operations of such party and its Subsidiaries taken as a whole; provided, however, that, with respect to this clause (a), a Material Adverse Effect shall not be deemed to include effects arising out of, relating to or resulting from (A) changes after the date hereof in applicable GAAP or regulatory accounting requirements or interpretations thereof, (B) changes after the date hereof in Laws, rules or regulations of general applicability to companies in the industries in which such party and its Subsidiaries operate or interpretations thereof, (C) changes after the date hereof in global, national or regional political conditions (including the outbreak, continuation or escalation of war or acts of terrorism (whether or not declared) or cyberattacks) or economic or market conditions (including equity, credit and debt markets, as well as changes in interest rates) affecting the financial services industry generally and not specifically relating to such party or its Subsidiaries, (D) changes after the date hereof, resulting from hurricanes, earthquakes, tornados, floods, wildfires or other natural disasters or from any outbreak of any disease, pandemic, epidemic, or other public health event (including any law, directive or guideline issued by a Governmental Entity in response thereto), (E) a decline in the trading price of a party’s common stock or a failure, in and of itself, to meet earnings projections or internal financial forecasts (it being understood that the underlying causes of such decline or failure may be taken into account in determining whether a Material Adverse Effect has occurred, except as otherwise excepted by this proviso), (F) the entry into or announcement of this Agreement or the transactions contemplated hereby or the consummation of the transactions contemplated hereby (including any effect on a party’s relationships with its customers or employees) (it being

-10-

understood that this Clause (F) shall not apply to a breach of any representation or warranty intended to address the announcement, pendency or consummation of the transactions contemplated hereby), (G) the expenses incurred by the Company or Parent in negotiating, documenting, effecting and consummating the transactions contemplated by this Agreement, (H) actions or omissions taken with the prior written consent of the other party or expressly required by this Agreement, or (I) any stockholder or shareholder litigation arising out of, related to, or in connection with this Agreement, the Mergers or the Bank Merger that is brought or threatened against a party or any members of a party’s Board of Directors from and following the date of this Agreement and prior to the Effective Time, except that effects attributable to or resulting from any of the changes, events, conditions or trends described in clauses (A), (B), (C), and (D) shall not be excluded to the extent of any materially disproportionate adverse impact they have on such party and its Subsidiaries, taken as a whole, as compared to other companies in the industry in which such party and its Subsidiaries operate; or (b) the ability of such party to timely consummate the transactions contemplated by this Agreement.

(b) True, complete and correct copies of the Second Amended and Restated Certificate of Incorporation of the Company (the “Company Certificate”), and the Amended and Restated Bylaws of the Company (the “Company Bylaws”), as in effect as of the date of this Agreement, have previously been publicly filed by the Company and made available to Parent. The Company Certificate and Company Bylaws made available to Parent are in full force and effect.

(c) Section 3.1(c) of the Company Disclosure Schedule sets forth a list of all Subsidiaries of the Company (which, for the avoidance of doubt, includes any Subsidiaries of such Subsidiaries), the ownership interest of the Company in each such Subsidiary, as well as the ownership interest of any other Person or Persons in each such Subsidiary, and a description of the business of each Subsidiary (or, in the case of a Subsidiary that the Company considers to be “inactive,” a statement to that effect and a description of the business previously conducted by such Subsidiary). Except as would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on the Company, each Subsidiary of the Company (i) is duly incorporated or duly formed, as applicable to each such Subsidiary, and validly existing and, where such concept is recognized under applicable Law, in good standing under the Laws of its jurisdiction of organization and (ii) has the requisite corporate (or similar) power and authority to own or lease all of its properties and assets and to carry on its business as it is now being conducted and is duly licensed or qualified to do business in each jurisdiction in which the nature of the business conducted by it, or the character or location of the properties and assets owned or leased by it, makes such licensing or qualification necessary. There are no restrictions on the ability of any Subsidiary of the Company to pay dividends or distributions to the Company, except, in the case of a Subsidiary that is a regulated entity, for restrictions on dividends or distributions generally applicable to all similarly regulated entities. As used in this Agreement, the term “Subsidiary” when used with respect to any Person, means any subsidiary of such Person within the meaning ascribed to such term in either Rule 1-02 of Regulation S-X promulgated by the SEC under the Exchange Act or Section 2(d) of the BHC Act. The deposit accounts of each Subsidiary of the Company that is an insured depository institution are insured by the Federal Deposit Insurance Corporation (the “FDIC”) through the Deposit Insurance Fund (as defined in Section 3(y) of the Federal Deposit Insurance Act of 1950) to the fullest extent permitted by Law, all premiums and assessments required to be paid in connection therewith

Each of Parent and the Company shall use its reasonable best efforts to have the Form S-4 declared effective under the Securities Act as promptly as practicable after such filings, and the Company and Parent shall thereafter mail or deliver the Joint Proxy Statement/Prospectus to their respective shareholders or stockholders, as applicable. Parent and the Company shall use their reasonable best efforts to keep the Form S-4 effective for so long as necessary to consummate the transactions contemplated by this Agreement. Parent shall also use its reasonable best efforts to obtain all necessary state securities Law or “blue sky” permits and approvals required to carry out the transactions contemplated by this Agreement, and the Company shall furnish all information concerning the Company and the holders of Company Common Stock as may be reasonably requested in connection with any such action.

(b) The parties shall cooperate with each other and use their reasonable best efforts to (i) promptly prepare and file all necessary documentation, to effect all applications, notices, petitions and filings (and in the case of the applications, notices, petitions and filings in respect of the Requisite Regulatory Approvals, use their reasonable best efforts to make such filings within thirty (30) calendar days of the date of this Agreement), and (ii) obtain as promptly as practicable all permits, consents, approvals and authorizations of all third parties and Governmental Entities that are necessary or advisable to consummate the Mergers, the Bank Merger and the other transactions contemplated by this Agreement, and to comply with the terms and conditions of all such permits, consents, approvals, and authorizations of all such third parties or Governmental Entities. Parent and the Company shall each use, and shall each cause their applicable Subsidiaries to use, reasonable best efforts to obtain each such Requisite Regulatory Approval as promptly as reasonably practicable. The Company and Parent shall have the right to review in advance and, to the extent practicable, each will consult with the other on,

-59-

in each case subject to applicable Laws and Section 9.11, all the non-confidential information relating to the Company or Parent (excluding any confidential financial information relating to individuals), as the case may be, and any of their respective Subsidiaries, that appear in any filing made with, or written materials submitted to, any third party or any Governmental Entity in connection with the transactions contemplated by this Agreement. In exercising the foregoing right, each of the parties shall act reasonably and as promptly as practicable. The parties shall consult with each other with respect to the obtaining of all permits, consents, approvals and authorizations (collectively the “Approvals”) of all third parties and Governmental Entities necessary or advisable to consummate the Mergers, the Bank Merger and the other transactions contemplated by this Agreement and each party will keep the other apprised of the status of matters relating to such Approvals and the completion of the Mergers, the Bank Merger and the other transactions contemplated by this Agreement. Each party shall consult with the other in advance of any material meeting or conference with any Governmental Entity in connection with the Mergers, the Bank Merger and the other transactions contemplated by this Agreement and, to the extent permitted by such Governmental Entity, give the other party and/or its counsel the opportunity to attend and participate in any such meetings and conferences that are substantive in-person or, if pre-scheduled, telephonic or virtual meetings, in each case subject to applicable Law; provided, that each party shall promptly advise the other party with respect to substantive matters that are addressed in any such meeting or conference with any Governmental Entity which the other party does not attend or participate in connection with or affecting the transactions contemplated by this Agreement, to the extent permitted by such Governmental Entity and subject to applicable Law and Section 9.11. As used in this Agreement, “Requisite Regulatory Approvals” means (i) all regulatory consents, registrations, approvals (and the expiration or termination of all statutory waiting periods in respect thereof), permits and authorizations required to be obtained prior to and in order to effect the consummation of the Merger, the Second Step Merger and the Bank Merger by the Company, Parent, Merger Sub or any of their respective Subsidiaries from the Federal Reserve, the FDIC and the DCBS or (ii) as set forth in Sections 3.4 and 4.4 that are necessary to consummate the transactions contemplated by this Agreement (including the Merger, the Second Step Merger and the Bank Merger) or those the failure of which to be obtained would reasonably be expected to have a Material Adverse Effect on the Surviving Entity.

(c) Each of Parent and the Company shall, upon request, furnish to the other all information concerning itself, its Subsidiaries, directors, officers and shareholders or stockholders, as applicable, and such other matters as may be reasonably necessary or advisable in connection with the Joint Proxy Statement/Prospectus, the Form S-4 or any other statement, filing, notice or application made by or on behalf of Parent, the Company or any of their respective Subsidiaries to any Governmental Entity in connection with the Merger, the Second Step Merger, the Bank Merger and the other transactions contemplated by this Agreement.

(d) In furtherance and not in limitation of the foregoing, each party shall use its reasonable best efforts to respond to any request for information, resolve any objection that may be asserted by any Governmental Entity with respect to this Agreement or the transactions contemplated hereby, and avoid the entry of, or have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that would restraint, prevent or delay the Closing. Notwithstanding the foregoing, nothing contained in this Agreement shall be deemed to require Parent and the Company or any of their respective

-60-

Subsidiaries, and neither Parent and the Company nor any of their respective Subsidiaries shall be permitted (without the written consent of the other party), to take any action, or commit to take any action, or agree to any condition or restriction, in connection with obtaining the foregoing permits, consents, approvals and authorizations of Governmental Entities or Regulatory Agencies that would reasonably be expected to have a Material Adverse Effect on the Surviving Entity and its Subsidiaries, taken as a whole, after giving effect to the Mergers and the Bank Merger (a “Materially Burdensome Regulatory Condition”).

(e) Each of Parent and the Company shall promptly advise the other upon receiving any communication from any Governmental Entity the consent or approval of which is required for consummation of the Merger, the Second Step Merger, the Bank Merger and the other transactions contemplated by this Agreement that causes such party to believe that there is a reasonable likelihood that any Requisite Regulatory Approval will not be obtained or that the receipt of any such approval may be materially delayed.

6.2 Reasonable Best Efforts. Subject to the terms and conditions of this Agreement, each of the Company and Parent agrees to cooperate with the other and use its, and cause its Subsidiaries to use their, reasonable best efforts in good faith to take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary, proper or desirable, or advisable on its part under this Agreement or under applicable Laws to consummate and make effective the Mergers, the Bank Merger and the other transactions contemplated hereby as promptly as practicable, including the satisfaction of the conditions set forth in Article 7 hereof.

6.3 Access to Information.

(a) Upon reasonable notice and subject to applicable Laws, for the purposes of preparing for the Mergers, the Bank Merger and the other matters contemplated by this Agreement, the Company shall, and shall cause each of its Subsidiaries to, afford to the officers, employees, accountants, counsel, advisors, agents and other Representatives of Parent, reasonable access, during normal business hours during the period prior to the earlier of the Effective Time or the termination of this Agreement in accordance with its terms, to all its properties, books, contracts, commitments, personnel and records, and the Company and its Subsidiaries and, during such period, the Company shall, and shall cause its Subsidiaries to, make available to Parent (i) a copy of each report, schedule, registration statement and other document filed or received by it during such period pursuant to the requirements of federal securities Laws or federal or state banking Laws (other than reports or documents that the Company is not permitted to disclose under applicable Law), (ii) all other information concerning its business, properties and personnel as Parent may reasonably request and (iii) access to the necessary information (including the Company’s own good faith estimates as available and third-party reports, if any, commissioned by the Company at Parent’s request) in order to prepare a good faith estimate of the potential impact of Sections 280G and 4999 of the Code with respect to amounts potentially payable to senior executives of the Company in connection with the consummation of the transactions contemplated by this Agreement; provided, that any investigation or request pursuant to this Section 6.3(a) shall not interfere unreasonably with normal operations of the Company and its Subsidiaries. Upon the reasonable request of the Company, Parent shall furnish such reasonable information about it and its business as is reasonably relevant to the Company and its stockholders. Neither the Company

-61-

nor Parent, nor any of their respective Subsidiaries, shall be required to provide access to or to disclose information to the extent such access or disclosure would violate or prejudice the rights of such party’s or its Subsidiaries’ customers, jeopardize the attorney-client privilege of such party or its Subsidiaries (after giving due consideration to the existence of any common interest, joint defense or similar agreement between the parties) or contravene any Law or binding agreement entered into prior to the date of this Agreement. The parties shall make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply. In addition to the foregoing, (i) the Company shall use reasonable best efforts to provide Parent with at least two (2) Business Days’ notice of its intent to enter into any Company Loan equal to or greater than $10,000,000 and (ii) the Company shall use reasonable best efforts to provide Parent on a monthly basis with a listing of all new and renewed Company Loans and loan modifications, payoffs of Company Loans and purchases of Company Loans in the preceding month.

(b) All nonpublic information and materials provided pursuant to this Agreement shall be subject to the provisions of the Confidentiality Agreement entered into between Parent and the Company dated as of February 11, 2025 (the “Confidentiality Agreement”).

(c) No investigation by a party hereto or its representatives shall affect or be deemed to modify or waive any representations, warranties or covenants of the other party set forth in this Agreement and nothing contained in this Agreement shall give either party, directly or indirectly, the right to control or direct the operations of the other party prior to the Effective Time.

6.4 Shareholder Approval and Stockholder Approval. Parent and the Company shall call the Parent Special Meeting and the Company Special Meeting, respectively, to be held as soon as reasonably practicable after the Form S-4 is declared effective, and in any event within sixty (60) calendar days after the Form S-4 is declared effective, for the purpose of obtaining (a) the Parent Shareholder Approval and the Company Stockholder Approval required in connection with this Agreement and the Merger and (b) if so desired and mutually agreed, a vote upon other matters of the type customarily brought before a meeting of shareholders or stockholders, as applicable, in connection with the approval of a merger agreement or the transactions contemplated thereby, and each of Parent and the Company shall use its reasonable best efforts to cause such meetings to occur as soon as reasonably practicable and on the same date. Each of Parent and the Company and their respective boards of directors shall use its reasonable best efforts to obtain from the shareholders or stockholders, as applicable, of Parent and the Company, as applicable, the Parent Shareholder Approval and the Company Stockholder Approval, as applicable, including by communicating to the respective shareholders or stockholders, as applicable, of Parent and the Company its recommendation (and including such recommendation in the Joint Proxy Statement/Prospectus) that the stockholders of the Company approve this Agreement, in the case of the Company Board, or approve the Parent Share Issuance, in the case of the Parent Board (the “Company Board Recommendation” and the “Parent Board Recommendation,” respectively). Each of Parent and the Company and their respective boards of directors shall not (i) withhold, withdraw, modify or qualify in a manner adverse to the other party the Parent Board Recommendation, in the case of Parent, or the Company Board Recommendation, in the case of the Company, (ii) fail to make the Parent

-62-

Board Recommendation, in the case of Parent, or the Company Board Recommendation, in the case of the Company, in the Joint Proxy Statement/Prospectus, (iii) adopt, approve, recommend or endorse an Acquisition Proposal or publicly announce an intention to adopt, approve, recommend or endorse an Acquisition Proposal, (iv) fail to publicly and without qualification (A) recommend against any Acquisition Proposal or (B) reaffirm the Parent Board Recommendation, in the case of Parent, or the Company Board Recommendation, in the case of the Company, in each case within ten (10) Business Days (or such fewer number of days as remains prior to the Parent Special Meeting or the Company Special Meeting, as applicable) after an Acquisition Proposal is made public or any request by the other party to do so, or (v) publicly propose to do any of the foregoing (any of the foregoing, a “Recommendation Change”). However, subject to Section 8.1 and Section 8.2, if the Parent Board or the Company Board, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that it would more likely than not result in a violation of its fiduciary duties under applicable Law to make or continue to make the Parent Board Recommendation or the Company Board Recommendation, as applicable, such board of directors may, in the case of Parent, prior to the receipt of the Parent Shareholder Approval, and in the case of the Company, prior to the receipt of the Company Stockholder Approval, submit this Agreement to its stockholders without recommendation (although the resolutions approving this Agreement as of the date hereof may not be rescinded or amended), in which event such board of directors may communicate the basis for its lack of a recommendation to its stockholders in the Joint Proxy Statement/Prospectus or an appropriate amendment or supplement thereto to the extent required by Law; provided, that such board of directors may not take any actions under this sentence unless it (A) gives the other party at least four (4) Business Days’ prior written notice of its intention to take such action and a reasonable description of the event or circumstances giving rise to its determination to take such action (including, in the event such action is taken in response to an Acquisition Proposal, the latest material terms and conditions of, and the identity of the third party making, any such Acquisition Proposal, or any amendment or modification thereof, or describe in reasonable detail such other event or circumstances) and (B) at the end of such notice period, takes into account any amendment or modification to this Agreement proposed by the other party and, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that it would nevertheless more likely than not result in a violation of its fiduciary duties under applicable Law to make or continue to make the Parent Board Recommendation or the Company Board Recommendation, as the case may be. Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of this Section 6.4 and will require a new notice period as referred to in this Section 6.4. Parent or the Company shall adjourn or postpone the Parent Special Meeting or the Company Special Meeting, as the case may be, if, as of the time for which such meeting is originally scheduled there are insufficient shares of Parent Common Stock or Company Common Stock, as the case may be, represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting, or if on the date of such meeting Parent or the Company, as applicable, has not received proxies representing a sufficient number of shares necessary to obtain the Parent Shareholder Approval or the Company Stockholder Approval. Notwithstanding anything to the contrary herein, unless this Agreement has been terminated in accordance with its terms, (x) the Parent Special Meeting shall be convened and the Parent Share Issuance shall be submitted to the shareholders of Parent at the Parent Special Meeting and (y) the Company Special Meeting shall be convened and this Agreement shall be submitted to the stockholders of the Company at the Company Special Meeting, and nothing contained herein shall be deemed to relieve either Parent or the Company of such obligation.

6.5 Nasdaq Listing. Prior to the Closing Date, Parent shall file with Nasdaq any required notices or forms with respect to the shares of Parent Common Stock to be issued in the Merger in accordance with Nasdaq’s rules.

6.6 Employee Matters.

(a) During the period commencing at the Effective Time and ending on the date that is twelve (12) months following the Effective Time, the Surviving Entity shall, or shall cause each of its Subsidiaries to, provide each employee who is actively employed by the Company or any of its Subsidiaries on the Closing Date (each, a “Continuing Employee”) while employed by Parent or any of its Subsidiaries following the Effective Time with: (i) base salary or wages, as applicable, no less favorable than the base salary or wages provided to such Continuing Employee immediately prior to the Effective Time; (ii) annual cash bonus opportunities no less favorable than annual cash bonus opportunities provided by Parent to similarly-situated employees of Parent; and (iii) pension and welfare benefits (excluding defined benefit, equity and long-term incentive compensation) which, in the aggregate, are no less favorable than employee benefits provided by Parent to similarly situated employees of Parent; provided, however, that until such time as Parent shall cause Continuing Employees to participate in the Parent Benefit Plans, a Continuing Employee’s continued participation in the Company Benefit Plans shall be deemed to satisfy the foregoing clause (iii) of this sentence (it being understood that participation in Parent Benefit Plans may commence at different times with respect to each Company Benefit Plan). The parties hereby acknowledge and agree to the terms and conditions of, and from and after the Closing Parent shall assume and honor the obligations of, the retention and severance arrangements set forth in Section 6.6(a) of the Company Disclosure Schedule.

(b) Upon Continuing Employees’ enrollment in Parent Benefit Plans, such Continuing Employees will, consistent with the provisions of Section 6.6(a) above, become participants in all Parent Benefit Plans on the same terms and conditions as similarly situated employees of Parent. Without limiting the generality of the foregoing, prior service credit for each Continuing Employee’s service with the Company and its Subsidiaries (and their respective predecessors), except as expressly provided otherwise herein, shall be given by Parent with respect to all Parent Benefit Plans to the extent that such crediting of service does not result in duplication of benefits, but not for accrual of benefits under any defined benefit pension plan. If any Continuing Employee becomes eligible to participate in any Parent Benefit Plan that provides medical, vision, prescription drug, hospitalization or dental benefits, Parent shall use commercially reasonable best efforts to (a) cause any pre-existing condition limitations or eligibility waiting periods under such Parent Benefit Plan to be waived with respect to such Continuing Employee and his or her covered dependents to the extent such limitation or waiting period would have been waived or satisfied under the Company Benefit Plan in which such Continuing Employee participated, and (b) recognize for purposes of annual deductible, co-pay and out-of-pocket limits under such Parent Benefit Plan, deductible, co-pays and out-of-pocket expenses incurred by such Continuing Employee and his or her covered dependents under any Company Benefit Plan during the plan year in which they commence participation in such Parent Benefit Plan.

(c) If requested in writing by Parent at least thirty (30) calendar days prior to the Effective Time, the Company shall take (or cause to be taken) all actions reasonably determined by Parent to be necessary or appropriate to terminate, effective not later than the day immediately prior to the Effective Time, any Company Benefit Plans that contain a cash or deferred arrangement intended to qualify under Section 401(k) of the Code. In the event that Parent requests that such plan(s) be terminated, the Company shall provide Parent with evidence that such plan(s) has been terminated (the form and substance of which shall be subject to review and approval by Parent, approval of which shall not be unreasonably withheld, conditioned or delayed) not later than the day immediately preceding the Effective Time. Effective as of the Effective Time, Parent shall have in effect a defined contribution plan that is qualified under Section 401(a) of the Code, which plan shall accept the transfer of account balances (including promissory notes evidencing all outstanding loans) of each participant in the Company Benefit Plans terminated under this Section 6.6(c).

(d) The parties shall take the actions set forth on Section 6.6(d) of the Company Disclosure Schedule.

(e) From the date hereof until the earlier of the Effective Time or the termination of this Agreement, the Company and its Subsidiaries shall not make any written communications to any of their employees regarding compensation, benefits or other employment-related matters affected by the transactions contemplated by this Agreement that are inconsistent with any talking points agreed to by the Company and Parent unless the Company or such Subsidiary first consults with Parent and reflects any reasonable comments received from Parent.

(f) Nothing contained in this Agreement shall, or is intended to, (i) be treated as an amendment or modification of any particular Company Benefit Plan or Parent Benefit Plan, (ii) alter or limit the ability of Parent, the Company or any of their respective Affiliates to amend, modify or terminate any Company Benefit Plan or Parent Benefit Plan after the Effective Time, (iii) alter or limit the ability of Parent, the Company or any of their respective Affiliates to terminate the employment of any Continuing Employee after the Effective Time, or (iv) create any third-party beneficiary rights in any employee of the Company or any of its Subsidiaries, any beneficiary or dependent thereof, or any collective bargaining representative thereof, with respect to the compensation, terms and conditions of employment and/or benefits that may be provided to any Continuing Employee by Parent, the Company or any of their respective Affiliates or under any Parent Benefit Plan.

(g) Following the Second Effective Time, Parent shall cause the Surviving Entity and the Subsidiaries of the Surviving Entity to satisfy their obligations under this Section 6.6.

-65-

6.7 Indemnification; Directors’ and Officers’ Insurance.

(a) From and after the Effective Time, the Surviving Entity shall indemnify and hold harmless each present and former director, officer and employee of the Company and its Subsidiaries (in each case, when acting in such capacity) (collectively, the “Indemnified Parties”) against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, damages or liabilities incurred in connection with any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, whether arising before or after the Effective Time, arising out of actions or omissions occurring at or prior to the Effective Time, including the transactions contemplated by this Agreement, to the extent they are indemnified by the Company or its Subsidiaries on the date hereof, and the Surviving Entity shall also advance expenses as incurred, in each case, to the fullest extent permitted under applicable Law; provided, that in the case of advancement of expenses, the Indemnified Party to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such Indemnified Party is not entitled to indemnification. The Surviving Entity shall reasonably cooperate with the Indemnified Parties in the defense of any such claim, action, suit, proceeding or investigation.

(b) For a period of six (6) years following the Effective Time, the Surviving Entity will provide and cause to be maintained director’s and officer’s liability insurance (“D&O Insurance”) with respect to claims against the present and former officers and directors of the Company or any of its Subsidiaries (determined as of the Effective Time) arising from facts or events occurring at or before the Effective Time (including the transactions contemplated by this Agreement and the approval thereof), which insurance will contain at least the same coverage and amounts, and contain terms and conditions no less advantageous to the Indemnified Party as that coverage currently provided by the Company; provided, however, that in no event shall the Parent or Surviving Entity be required to expend, on an annual basis, an amount in excess of 300% of the aggregate annual premium paid as of the date hereof by the Company for any such insurance (the “Premium Cap”); provided, further, that if such premiums for such insurance would at any time exceed the Premium Cap, Parent or the Surviving Entity shall obtain and cause to be maintained policies of insurance that provide, in the Surviving Entity’s good faith determination, the maximum coverage available at an annual premium equal to the Premium Cap. In lieu of the foregoing, Parent or the Company, in consultation with, but only upon the consent of Parent, may (and at the request of Parent, the Company shall use its reasonable best efforts to) obtain at or prior to the Effective Time a six (6)-year “tail” policy providing equivalent coverage to that described in the preceding sentence if and to the extent that the same may be obtained for an amount that, in the aggregate, does not exceed the Premium Cap, and if such “tail” policy has been obtained prior to the Effective Time, Parent shall cause such policy to be maintained in full force and effect for its full term.

(c) The provisions of this Section 6.7 shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, each Indemnified Party and his or her heirs and representatives. If the Surviving Entity or any of its successors or assigns (i) consolidates with or merges into any other person and is not the continuing or surviving entity of such consolidation or merger, or (ii) transfers all or substantially all of its assets or deposits to any other person or engages in any similar transaction, then in each such case, the Surviving Entity will cause proper provision to be made so that the successors and assigns of the Surviving Corporation will expressly assume the obligations set forth in this Section 6.7.

-66-

6.8 Exemption from Liability Under Rule 16(b)-3. Parent and the Company agree that, in order to most effectively compensate and retain Company Insiders, both prior to and after the Effective Time, it is desirable that Company Insiders not be subject to a risk of liability under Section 16(b) of the Exchange Act to the fullest extent permitted by applicable Law in connection with the conversion of shares of Company Common Stock and Company Equity Awards into Parent Common Stock or Parent Equity Awards, as applicable, in connection with the Merger, and for that compensatory and retentive purpose agree to the provisions of this Section 6.8, the Company shall deliver to Parent in a reasonably timely fashion prior to the Effective Time accurate information regarding those officers and directors of the Company subject to the reporting requirements of Section 16(a) of the Exchange Act (the “Company Insiders”), and the Board of Directors of Parent and of the Company, or a committee of non-employee directors thereof (as such term is defined for purposes of Rule 16b-3(d) under the Exchange Act), shall reasonably promptly thereafter, and in any event prior to the Effective Time, take all such steps as may be required to cause (in the case of the Company) any dispositions of Company Common Stock or Company Equity Awards by the Company Insiders, and (in the case of Parent) any acquisitions of Parent Common Stock or Parent Equity Awards by any Company Insiders who, immediately following the Merger, will be officers or directors of the Surviving Entity subject to the reporting requirements of Section 16(a) of the Exchange Act, in each case pursuant to the transactions contemplated by this Agreement, to be exempt from liability pursuant to Rule 16b-3 under the Exchange Act to the fullest extent permitted by applicable Law.

6.9 Acquisition Proposals.

(a) Each party agrees that it will not, will cause each of its Subsidiaries not to, and will use its reasonable best efforts to cause its and their respective officers, directors, employees, agents, advisors and representatives (collectively, “Representatives”) not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate inquiries or proposals with respect to any Acquisition Proposal, (ii) engage or participate in any negotiations with any person concerning any Acquisition Proposal, (iii) provide any confidential or nonpublic information or data to, or have or participate in any discussions with, any person relating to any Acquisition Proposal (except to notify a person that has made or, to the knowledge of such party, is making any inquiries with respect to, or is considering making, an Acquisition Proposal, of the existence of the provisions of this Section 6.9) or (iv) unless this Agreement has been terminated in accordance with its terms, approve or enter into any term sheet, letter of intent, commitment, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other similar agreement (whether written or oral, binding or nonbinding) (other than a confidentiality agreement referred to and entered into in accordance with this Section 6.9) in connection with or relating to any Acquisition Proposal. Notwithstanding the foregoing, in the event that after the date of this Agreement and prior to the receipt of the Parent Shareholder Approval, in the case of Parent, or the Company Stockholder Approval, in the case of the Company, a party receives an unsolicited bona fide written Acquisition Proposal, such party may, and may permit its Subsidiaries and its and its Subsidiaries’ Representatives to, furnish or cause to be furnished confidential or nonpublic information or data and participate in such

-67-

negotiations or discussions with the person making the Acquisition Proposal if the board of directors of such party concludes in good faith (after receiving the advice of its outside counsel, and with respect to financial matters, its financial advisors) that failure to take such actions would be more likely than not to result in a violation of its fiduciary duties under applicable Law; provided, that prior to furnishing any confidential or nonpublic information permitted to be provided pursuant to this sentence, such party shall have entered into a confidentiality agreement with the person making such Acquisition Proposal on terms no less favorable to it than the Confidentiality Agreement, which confidentiality agreement shall not provide such person with any exclusive right to negotiate with such party. Each party will, and will cause its Subsidiaries and Representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any person other than the other party with respect to any Acquisition Proposal. Each party will promptly (within twenty-four (24) hours) advise the other party following receipt of any Acquisition Proposal or any inquiry which would reasonably be expected to lead to an Acquisition Proposal, and the substance thereof (including the terms and conditions of and the identity of the person making such inquiry or Acquisition Proposal), will provide the other party with an unredacted copy of any such Acquisition Proposal and any draft agreements, proposals or other materials received from or on behalf of the person making such inquiry or Acquisition Proposal in connection with such inquiry or Acquisition Proposal, and will keep the other party apprised of any related developments, discussions and negotiations on a current basis, including any amendments to or revisions of the terms of such inquiry or Acquisition Proposal. Each party shall use its reasonable best efforts to enforce any existing confidentiality or standstill agreements to which it or any of its Subsidiaries is a party in accordance with the terms thereof. As used in this Agreement, “Acquisition Proposal” means, with respect to a party, other than the transactions contemplated by this Agreement, any offer, proposal or inquiry relating to, or any third-party indication of interest in, (i) any acquisition or purchase, direct or indirect, of 25% or more of the consolidated assets of such party and its Subsidiaries or 25% or more of any class of equity or voting securities of such party or its Subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of such party, (ii) any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in such third party beneficially owning 25% or more of any class of equity or voting securities of such party or its Subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of such party, or (iii) a merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving the Company or its Subsidiaries whose assets, individually or in the aggregate, constitute 25% or more of the consolidated assets of such party.

(b) Nothing contained in this Agreement shall prevent a party or its board of directors from complying with Rules 14d-9 and 14e-2 under the Exchange Act with respect to an Acquisition Proposal; provided, that such rules will in no way eliminate or modify the effect that any action pursuant to such rules would otherwise have under this Agreement.

6.10 Takeover Laws. No party will take any action that would cause the transactions contemplated by this Agreement to be subject to requirements imposed by any Takeover Law and each of them will take all necessary steps within its control to exempt (or ensure the continued exemption of) the transactions contemplated by this Agreement from, or if necessary challenge the validity or applicability of, any applicable Takeover Law, as now or hereafter in

-68-

effect. If any Takeover Laws become applicable to this Agreement or the transactions contemplated hereby or thereby, including the Merger, the parties shall take all reasonable action necessary to ensure that the transactions contemplated by this Agreement, including the Merger, may be consummated as promptly as practicable on the terms contemplated hereby and otherwise to minimize the effect of such Takeover Law on this Agreement or the transactions contemplated hereby, including the Merger.

6.11 Notification of Certain Matters. The Company and Parent will give prompt notice to the other of any fact, event or circumstance known to it that (a) is reasonably likely, individually or taken together with all other facts, events and circumstances known to it, to result in any Material Adverse Effect with respect to it or (b) would cause or constitute a material breach of any of its representations, warranties, covenants or agreements contained herein that reasonably could be expected to give rise, individually or in the aggregate, to a failure of a condition in Article 7; provided, that any failure to give notice in accordance with the foregoing with respect to any breach shall not be deemed to constitute a violation of this Section 6.11 or the failure of any condition set forth in Section 7.2 or 7.3 to be satisfied, or otherwise constitute a breach of this Agreement by the party failing to give such notice, in each case unless the underlying breach would independently result in a failure of the conditions set forth in Section 7.2 or 7.3 to be satisfied.

6.12 Litigation. Each party shall give the other party prompt notice in writing of any shareholder or stockholder (as applicable) litigation against such party or its directors or officers relating to the transactions contemplated by this Agreement, and the Company shall give Parent the opportunity to participate (at Parent’s expense) in the defense or settlement of any such litigation. Each party shall give the other a reasonable opportunity to review and comment on all filings or responses to be made by such party in connection with any such litigation, and will in good faith take such comments into account. The Company shall not agree to settle any such litigation without Parent’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed; provided, that Parent shall not be obligated to consent to any settlement which does not include a full release of Parent and its Affiliates or which imposes an injunction or other equitable relief after the Effective Time upon the Surviving Entity or any of its Affiliates.

6.13 Treatment of Company Debt. Upon the Second Effective Time (or at the effective time of the Bank Merger for any debt of Pacific Premier Bank), Parent, or Umpqua Bank, as applicable, shall assume the due and punctual performance and observance of the covenants and other obligations to be performed by the Company or Pacific Premier Bank, as applicable, under the definitive documents governing the then-outstanding indebtedness and other instruments related thereto set forth on Section 6.13 of the Company Disclosure Schedule, including the due and punctual payment of the principal of (and premium, if any) and interest thereon, to the extent required and permitted thereby. In connection therewith, (a) Parent shall, and shall cause Umpqua Bank to, cooperate and use reasonable best efforts to execute and deliver any supplemental indentures, if applicable, and (b) the Company shall, and shall cause Pacific Premier Bank to, cooperate and use reasonable best efforts to execute and deliver any supplemental indentures, officer’s certificates or other documents and to provide any opinions of counsel to the trustee thereof, in each case, required to make such assumption effective as of the Second Effective Time, or the effective time of the Bank Merger, as applicable.

ARTICLE 8

TERMINATION AND AMENDMENT

8.1 Termination. This Agreement may be terminated at any time prior to the Effective Time, whether before or after receipt of the Parent Shareholder Approval or the Company Stockholder Approval:

(a) by mutual written consent of Parent and the Company;

-74-

(b) by either Parent or the Company if any Governmental Entity that must grant a Requisite Regulatory Approval has denied approval of the Mergers or the Bank Merger and such denial has become final and nonappealable or any Governmental Entity of competent jurisdiction shall have issued a final and nonappealable order, injunction, decree or other legal restraint or prohibition permanently enjoining or otherwise prohibiting or making illegal the consummation of the Mergers or the Bank Merger, unless the failure to obtain a Requisite Regulatory Approval shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the obligations, covenants and agreements of such party set forth herein;

(c) by either Parent or the Company if the Merger shall not have been consummated on or before April 23, 2026 (the “Termination Date”), unless the failure of the Closing to occur by the Termination Date shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the obligations, covenants and agreements of such party set forth herein; provided, however, that if the conditions to the Closing set forth in Section 7.1(b) or Section 7.1(d) (to the extent related to a Requisite Regulatory Approval) have not been satisfied or waived on or prior to such date but all other conditions to Closing set forth in Article 7 have been satisfied or waived (other than those conditions that by their nature can only be satisfied or waived at the Closing (so long as such conditions are reasonably capable of being satisfied)), the Termination Date will be automatically extended to July 23, 2026, and such date, as so extended, shall be the “Termination Date”;

(e) Each of Parent and the Company acknowledges that the agreements contained in this Section 8.2 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the other party would not enter into this Agreement; accordingly, if Parent or the Company, as the case may be, fails promptly to pay the amount due pursuant to this Section 8.2, and, in order to obtain such payment, the other party commences a suit which results in a judgment against the non-paying party for the Termination Fee or any portion thereof, such non-paying party shall pay the costs and expenses of the other party (including attorneys’ fees and expenses) in connection with such suit. In addition, if Parent or the Company, as the case may be, fails to pay the amounts payable pursuant to this Section 8.2, then such party shall pay interest on such overdue amounts (for the period commencing as of the date that such overdue amount was originally required to be paid and ending on the date that such overdue amount is actually paid in full) at a rate per annum equal to the “prime rate” published in The Wall Street Journal on the date on which such payment was required to be made for the period commencing as of the date that such overdue amount was originally required to be paid and ending on the date that such overdue amount is actually paid in full.

8.3 Fees and Expenses. All fees and expenses incurred in connection with the Mergers, this Agreement, and the transactions contemplated by this Agreement (including costs and expenses of printing and mailing the Joint Proxy Statement/Prospectus) shall be paid by the party incurring such fees or expenses, whether or not the Merger is consummated, except as otherwise provided in Section 8.2; provided, that the costs and expenses of printing and mailing the Joint Proxy Statement/Prospectus and all filing and other fees paid to the SEC or any other Governmental Entity in connection with the Merger shall be borne equally by Parent and the Company.

-77-

8.4 Amendment. This Agreement may be amended by the parties, by action taken or authorized by their respective Boards of Directors, at any time before or after approval of the matters presented in connection with the Merger by the shareholders or stockholders, as applicable, of the Company or Parent; provided, however, that after the receipt of the Parent Shareholder Approval or the Company Stockholder Approval, there may not be, without further approval of such shareholders or stockholders, as applicable, any amendment of this Agreement that requires further approval of such shareholders or stockholders, as applicable, under applicable Law. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties.

8.5 Extension; Waiver. At any time prior to the Effective Time, the parties, by action taken or authorized by their respective Boards of Directors, may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of the other party, (b) waive any inaccuracies in the representations and warranties contained in this Agreement or (c) waive compliance with any of the agreements or conditions contained in this Agreement. Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

Thereafter, each of the parties agrees that no public release or announcement or statement concerning this Agreement or the transactions contemplated hereby shall be issued by any party without the prior written consent of the other party (which consent shall not be unreasonably withheld, conditioned or delayed), except (a) as required by applicable Law or the rules or regulations of any applicable Governmental Entity or stock exchange to which the relevant party is subject, in which case the party required to make the release or announcement shall consult with the other party about, and allow the other party reasonable time to comment on, such release or announcement in advance of such issuance or (b) for such releases, announcements or statements that are consistent with other such releases, announcement or statements made after the date of this Agreement in compliance with this Section 9.8.

Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto in accordance herewith without notice or liability to any other person. In some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties hereto. Consequently, persons other than the parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

It is accordingly agreed that the parties shall be entitled to specific performance of the terms hereof including an injunction or injunctions to prevent breaches or threatened breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof (including the parties’ obligation to consummate the Mergers), this being in addition to any other remedies to which they are entitled at Law or equity. Each of the parties hereby further waives (a) any defense in any action for specific performance that a remedy at law would be adequate and (b) any requirement under any law to post security or a bond as a prerequisite to obtaining equitable relief.

9.11 Confidential Supervisory Information. Notwithstanding any other provision of this Agreement, no disclosure, representation or warranty shall be made (or other action taken) pursuant to this Agreement that would involve the disclosure of confidential supervisory information (including confidential supervisory information as defined or identified in 12 C.F.R. § 261.2(b) and 12 C.F.R. § 309.5(g)(8)) of a Governmental Entity by any party to this Agreement to the extent prohibited by applicable Law. To the extent legally permissible, appropriate substitute disclosures or actions shall be made or taken under circumstances in which the limitations of the preceding sentence apply.
