(a) Pacific Premier Common Stock. Each share of Pacific Premier Common Stock that is issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding and shall be unchanged by the Merger.

(b) (1) SDTB Common Stock. Subject to Sections 3.02, 3.05, 3.06, 3.07 and 9.05, each share of SDTB Common Stock issued and outstanding immediately prior to the Effective Time shall be converted into, and shall be canceled in exchange for, the right to receive:

Each Election Form shall permit the holder (or in the case of nominee record holders, the beneficial owner through proper instructions and documentation), subject to the conditions set forth in Section 3.01(b)(1), (i) to elect to receive PPBI Common Stock with respect to all of such holder's SDTB Common Stock (a "Stock Election"), (ii) to elect to receive cash with respect to all of such holder's SDTB Common Stock (a "Cash Election"), (iii) to elect to receive cash with respect to some of such holder's shares and shares of PPBI Common Stock with respect to such holder's remaining shares (a "Mixed Election") or (iv) to indicate that such holder makes no such election with respect to such holder's shares of SDTB Common Stock (a "Non-Election").

(c) Effective Election. Any election to receive PPBI Common Stock and/or cash shall have been properly made only if the agent designated by PPBI (who, if different than PPBI's then serving registrar and transfer agent, is reasonably acceptable to SDTB) to act as the exchange agent for purposes of conducting the election procedure and the exchange procedure described in Sections 3.01 and 3.02 (the "Exchange Agent") shall have actually received a properly completed

Election Form by the Election Deadline. Any Election Form may be revoked or changed by the person submitting such Election Form to the Exchange Agent (or any other Person to whom the subject shares of SDTB Common Stock are subsequently transferred) by written notice to the Exchange Agent only if such written notice is actually received by the Exchange Agent at or prior to the Election Deadline. The Exchange Agent shall have reasonable discretion to determine when any election, modification or revocation is received, whether any such election, modification or revocation has been properly made and to disregard immaterial defects in any Election Form, and any good faith decisions of the Exchange Agent regarding such matters shall be binding and conclusive. Neither PPBI nor the Exchange Agent shall be under any obligation to notify any person of any defect in an Election Form.

(d) Allocation. The Exchange Agent shall effect the allocation among holders of SDTB Common Stock of rights to receive PPBI Common Stock and/or cash in the Merger in accordance with the Election Forms as follows:

(i) Minimum Cash Consideration Undersubscribed. If the number of Cash Election Shares times the Per Share Cash Consideration is less than the Minimum Cash Consideration, then:

(1) all Cash Election Shares (subject to Section 3.06 with respect to Dissenting Shares) shall be converted into the right to receive cash;

(2) No-Election Shares shall then be deemed to be Cash Election Shares to the extent necessary to have the total number of Cash Election Shares (including Dissenting Shares) times the Per Share Cash Consideration equal the Minimum Cash Consideration. If less than all of the No-Election Shares need to be treated as Cash Election Shares, then the Exchange Agent shall select which No-Election Shares shall be treated as Cash Election Shares in such manner as the Exchange Agent shall determine, and all remaining No-Election Shares shall thereafter be treated as Stock Election Shares;

(3) if all of the No-Election Shares are treated as Cash Election Shares under the preceding subsection and the total number of Cash Election Shares times the Per Share Cash Consideration is less than the Minimum Cash Consideration, then the Exchange Agent shall convert on a pro rata basis as described below in Section 3.02(e) a sufficient number of Stock Election Shares into Cash Election Shares ("Reallocated Cash Shares") such that the sum of the number of Cash Election Shares plus the number of Reallocated Cash Shares times the Per Share Cash Consideration equals the Minimum Cash Consideration, and all Reallocated Cash Shares will be converted into the right to receive cash; and

(4) the Stock Election Shares which are not Reallocated Cash Shares shall be converted into the right to receive PPBI Common Stock.

(ii) Maximum Cash Consideration Oversubscribed. If the number of Cash Election Shares times the Per Share Cash Consideration is greater than the Maximum Cash Consideration, then:

(1) all Stock Election Shares and all No-Election Shares shall be converted into the right to receive PPBI Common Stock;

(2) the Exchange Agent shall convert on a pro rata basis as described below in Section 3.02(e) a sufficient number of Cash Election Shares (excluding any Dissenting Shares) ("Reallocated Stock Shares") such that the number of remaining Cash Election Shares (including Dissenting Shares) times the Per Share Cash Consideration equals the

Maximum Cash Consideration, and all Reallocated Stock Shares shall be converted into the right to receive PPBI Common Stock; and

(3) the Cash Election Shares (subject to Section 3.06 with respect to Dissenting Shares) which are not Reallocated Stock Shares shall be converted into the right to receive cash.

(iii) Minimum or Maximum Cash Consideration Satisfied. If the number of Cash Election Shares times the Per Share Cash Consideration is equal to the Minimum Cash Consideration or the Maximum Cash Consideration, then subparagraphs (d)(i) and (ii) above shall not apply and all Cash Election Shares (subject to Section 3.06 with respect to Dissenting Shares) shall be converted into the right to receive cash and all No-Election Shares and all Stock Election Shares will be converted into the right to receive PPBI Common Stock.

(e) Pro Rata Reallocations. In the event that the Exchange Agent is required pursuant to Section 3.02(d)(i)(3) to convert some Stock Election Shares into Reallocated Cash Shares, each holder of Stock Election Shares shall be allocated a pro rata portion of the total Reallocated Cash Shares. In the event the Exchange Agent is required pursuant to Section 3.02(d)(ii)(2) to convert some Cash Election Shares into Reallocated Stock Shares, each holder of Cash Election Shares shall be allocated a pro rata portion of the total Reallocated Stock Shares.

(f) Stock Consideration Adjustment. Notwithstanding any other provision of this Agreement, if at the time of the Closing, the aggregate value of the shares of PPBI Common Stock to be exchanged for shares of SDTB Common Stock is less than 45% of the sum of (i) the Aggregate Merger Consideration and (ii) the Option Merger Consideration, then PPBI shall direct the Exchange Agent to convert a minimum number of No-Election Shares and, to the extent necessary a minimum number of Cash Election Shares, into Stock Election Shares so that the aggregate value of the shares of PPBI Common Stock exchanged for shares of SDTB Common Stock constitutes 45% of the aggregate value of the sum of (i) the Aggregate Merger Consideration and (ii) the Option Merger Consideration. For purposes of this Section 3.02(f) only, the value of a share of PPBI Common Stock will be the PPBI Average Share Price.

3.03 Exchange Procedures.

(a) Mailing of Transmittal Material. Provided that SDTB has delivered, or caused to be delivered, to the Exchange Agent all information which is reasonably necessary for the Exchange Agent to perform its obligations as specified herein, the Exchange Agent shall, and PPBI shall cause the Exchange Agent to, mail or deliver to each holder of record of SDTB Common Stock, simultaneous with the mailing or delivery of the Election Form, a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to such Certificate(s) theretofore representing shares of SDTB Common Stock shall pass, only upon proper delivery of such Certificate(s) to the Exchange Agent and which shall have been approved in form by SDTB) advising such holder of the procedure for surrendering to the Exchange Agent such Certificate(s) in exchange for the consideration to which such holder may be entitled pursuant to Section 3.01(b) hereof deliverable in respect thereof pursuant to this Agreement. A letter of transmittal will be properly completed only if accompanied by Certificate or Certificates representing all shares of SDTB Common Stock covered thereby, subject to the provisions of paragraph (d) of this Section 3.03. For those holders of No-Election Shares who have not surrendered a properly completed letter of transmittal and/or Certificates evidencing such No-Election Shares before the Election Deadline, the Exchange Agent shall send such holders another letter of transmittal promptly following the Election Deadline indicating the allocation to such holders' No-Election Shares of rights to receive PPBI Common Stock and/or cash.

(b) PPBI Deliveries. At least one (1) day prior to the Closing, for the benefit of the holders of Certificates, (i) PPBI shall deliver to the Exchange Agent certificates, or at PPBI's option, evidence of shares in book entry form, representing the number of shares of PPBI Common Stock issuable to the holders of SDTB Common Stock as part of the Merger Consideration and (ii) PPBI shall deliver, or cause Pacific Premier to deliver, to the Exchange Agent, the cash portion of the Merger Consideration payable pursuant to this Article III, each to be given to the holders of SDTB Common Stock in exchange for their Certificates as provided in this Article III. The Exchange Agent shall not be entitled to vote or exercise any rights of ownership with respect to the shares of PPBI Common Stock held by it from time to time hereunder, except that it shall receive and hold all dividends or other distributions paid or distributed with respect to such shares for the account of the Persons entitled thereto.

(i) After completion of the allocation referred to in paragraph (d) of Section 3.02 and upon the Closing, each holder of an outstanding Certificate or Certificates who has surrendered such Certificate or Certificates to the Exchange Agent will, upon acceptance thereof by the Exchange Agent, be entitled to evidence of issuance in book entry form, or upon written request of such holder a certificate or certificates representing, the number of whole shares of PPBI Common Stock and/or the amount of cash into which the aggregate number of shares of SDTB Common Stock previously represented by such Certificate or Certificates surrendered shall have been converted pursuant to this Agreement and, if such holder's shares of SDTB Common Stock have been converted into PPBI Common Stock, any other distribution theretofore paid with respect to PPBI Common Stock issuable in the Merger, in each case, without interest. The Exchange Agent shall accept such Certificates upon compliance with such reasonable terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices.

(ii) If a holder of Certificates surrenders such Certificates and a properly executed letter of transmittal to the Exchange Agent at least five (5) Business Days prior to the Closing Date, then PPBI shall use commercially reasonable efforts to cause the Exchange Agent to deliver, within one (1) Business Day following the Closing Date, to such holder of Certificates the Merger Consideration into which the shares of SDTB Common Stock represented by such Certificates have been converted pursuant to Section 3.01(b). If a holder of Certificates surrenders such Certificates and a properly executed letter of transmittal to the Exchange Agent at any time after five (5) Business Days prior to the Closing Date, then PPBI shall use commercially reasonable efforts to cause the Exchange Agent to promptly, but in no event later than five (5) Business Days following receipt of such Certificates and properly executed letter of transmittal, deliver to such holder of Certificates the Merger Consideration into which the shares of SDTB Common Stock represented by such Certificate or Certificates have been converted pursuant to Section 3.01(b).

(iii) Each outstanding Certificate which prior to the Effective Time represented SDTB Common Stock and which is not surrendered to the Exchange Agent in accordance with the procedures provided for herein shall, except as otherwise herein provided, until duly surrendered to the Exchange Agent, be deemed to evidence ownership of the number of shares of PPBI Common Stock and/or the right to receive the amount of cash into which such SDTB Common Stock shall have been converted. After the Effective Time, there shall be no further transfer on the records of SDTB of Certificates representing shares of SDTB Common Stock and, if such Certificates are presented to SDTB for transfer, they shall be cancelled against delivery of certificates for PPBI Common Stock and/or cash as hereinabove provided. No dividends which have been declared will be remitted to any Person entitled to receive shares of PPBI Common Stock under Section 3.02 until such Person surrenders the Certificate

or Certificates representing SDTB Common Stock, at which time such dividends shall be remitted to such Person, without interest.

(d) Lost or Destroyed Certificates; Issuances of PPBI Common Stock in New Names. The Exchange Agent and PPBI, as the case may be, shall not be obligated to deliver cash and a certificate or certificates representing shares of PPBI Common Stock to which a holder of SDTB Common Stock would otherwise be entitled as a result of the Merger until such holder surrenders the Certificate or Certificates representing the shares of SDTB Common Stock for exchange as provided in this Section 3.03, or, in default thereof, an appropriate affidavit of loss and indemnity agreement and/or a bond in an amount as may be reasonably required in each case by PPBI. If any certificates evidencing shares of PPBI Common Stock are to be issued in a name other than that in which the Certificate evidencing SDTB Common Stock surrendered in exchange therefore is registered, it shall be a condition of the issuance thereof that the Certificate so surrendered shall be properly endorsed or accompanied by an executed form of assignment separate from the Certificate and otherwise in proper form for transfer and that the Person requesting such exchange pay to the Exchange Agent any transfer or other Tax required by reason of the issuance of a certificate for shares of PPBI Common Stock in any name other than that of the registered holder of the Certificate surrendered or otherwise establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(e) Unclaimed Merger Consideration. Any portion of the shares of PPBI Common Stock and cash delivered to the Exchange Agent by PPBI pursuant to Section 3.03(b) that remains unclaimed by the shareholders of SDTB for six months after the Effective Time (as well as any proceeds from any investment thereof) shall be delivered by the Exchange Agent to PPBI. Any shareholders of SDTB who have not theretofore complied with Section 3.03(c) shall thereafter look only to PPBI for the consideration deliverable in respect of each share of SDTB Common Stock such shareholder holds as determined pursuant to this Agreement without any interest thereon. If outstanding Certificates for shares of SDTB Common Stock are not surrendered or the payment for them is not claimed prior to the date on which such shares of PPBI Common Stock or cash would otherwise escheat to any governmental unit or agency, the unclaimed items shall, to the extent permitted by abandoned property and any other applicable law, become the property of PPBI (and to the extent not in its possession shall be delivered to it), free and clear of all claims or interest of any Person previously entitled to such property. Neither the Exchange Agent nor any party to this Agreement shall be liable to any holder of stock represented by any Certificate for any consideration paid to a public official pursuant to applicable abandoned property, escheat or similar laws. PPBI and the Exchange Agent shall be entitled to rely upon the stock transfer books of SDTB to establish the identity of those Persons entitled to receive the consideration specified in this Agreement, which books shall be conclusive with respect thereto. In the event of a dispute with respect to ownership of stock represented by any Certificate, PPBI and the Exchange Agent shall be entitled to deposit any consideration represented thereby in escrow with an independent third party and thereafter be relieved with respect to any claims thereto.

3.04 Rights as Shareholders; Stock Transfers. At the Effective Time, holders of SDTB Common Stock shall cease to be, and shall have no rights as, shareholders of SDTB other than to receive the consideration provided under this Article III.

3.05 No Fractional Shares. Notwithstanding any other provision of this Agreement, neither certificates nor scrip for fractional shares of PPBI Common Stock shall be issued in the Merger. Each holder of SDTB Common Stock who otherwise would have been entitled to a fraction of a share of PPBI Common Stock (after taking into account all Certificates delivered by such holder) shall receive in lieu thereof cash (without interest) in an amount determined by multiplying the fractional share interest to which such holder would otherwise be entitled by $13.41, rounded to the nearest whole cent.

No such holder shall be entitled to dividends, voting rights or any other rights in respect of any fractional share.

3.06 Dissenting Shares. Each outstanding share of SDTB Common Stock the holder of which has perfected his right to dissent pursuant to Chapter 13 of the CGCL, including making a demand of SDTB to purchase his shares pursuant to Section 1301 of Chapter 13 of the CGCL and submitting his shares for endorsement pursuant to Section 1302 of Chapter 13 of the CGCL, and has not effectively withdrawn or lost such right as of the Effective Time (the "Dissenting Shares") shall not be converted into or represent a right to receive the Merger Consideration hereunder, and the holder thereof shall be entitled only to such rights as are granted by the CGCL. SDTB shall give PPBI prompt notice upon receipt by SDTB of any such written demands for payment of the fair value of such shares of SDTB Common Stock and of withdrawals of such demands and any other instruments provided pursuant to the CGCL. If any holder of Dissenting Shares shall have effectively withdrawn or lost the right to dissent (through failure to perfect or otherwise), the Dissenting Shares held by such holder shall be converted on a share by share basis into the right to receive the Merger Consideration in accordance with the applicable provisions of this Agreement. Any payments made in respect of Dissenting Shares shall be made by PPBI or the Surviving Bank within the time period set forth in the CGCL.

3.07 Anti-Dilution Provisions. If, between the date hereof and the Effective Time, the shares of PPBI Common Stock shall be changed into a different number or class of shares by reason of any reclassification, recapitalization, split-up, combination, exchange of shares or readjustment, or a stock dividend thereon shall be declared with a record date within said period, the Per Share Stock Consideration shall be adjusted accordingly; provided that an offering or sale of PPBI Common Stock shall not be deemed a reclassification, recapitalization, split-up, combination, exchange of shares or readjustment of the PPBI Common Stock.

3.08 Withholding Rights. PPBI (through the Exchange Agent, if applicable) shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement to any holder of shares of SDTB Common Stock such amounts as PPBI is required under the Code or any state, local or foreign Tax law or regulation thereunder to deduct and withhold with respect to the making of such payment. Any amounts so withheld shall be treated for all purposes of this Agreement as having been paid to the holder of SDTB Common Stock in respect of which such deduction and withholding was made by PPBI.

3.09 SDTB Options.

(i) As soon as practicable after the date hereof, but in no event less than one hundred (100) days prior to the anticipated Closing Date, the SDTB Board shall declare (an "Acceleration Declaration") that each SDTB Option that is then outstanding, but that is not then exercisable, shall become fully vested and exercisable for a period of three (3) months ending immediately before the anticipated Closing Date, in accordance with the SDTB Stock Option Plan, with such vesting and exercise effective on the Closing Date.

(ii) Following such Acceleration Declaration, but in no event less than ninety (90) days prior to the anticipated Closing Date, SDTB shall deliver a written notification to each holder of a SDTB Option, informing him or her of such event.

(iii) At the Closing Date, each SDTB Option, vested or unvested, that remains outstanding shall be cancelled in accordance with the SDTB Stock Option Plan and shall only entitle the holder of such SDTB Option to receive from PPBI, as soon as reasonably practicable after the Effective Time, but in no event later than three (3) days after the Effective Date, a single lump sum cash payment, equal to the product of (A) the number of shares of SDTB Common Stock subject to such SDTB Option immediately prior to the Closing, and (B) the excess, if any, of the Per Share Cash Consideration over the exercise price per share of such SDTB Option (the

"Option Merger Consideration"), less any applicable Taxes required to be withheld with respect to such payment. If the exercise price per share of any such SDTB Option is equal to or greater than the Per Share Cash Consideration, such SDTB Option shall be canceled without any cash payment being made in respect thereof.

(iv) At least thirty (30) days prior to the expected Closing Date, SDTB shall send a request to all holders of all of the then-outstanding SDTB Options requesting that they return a written acknowledgment with regard to the cancellation of his or her SDTB Options and the payment therefor in accordance with the terms of this Agreement. SDTB shall use its reasonable best efforts to obtain the written acknowledgment of each holder of a then-outstanding SDTB Option with regard to the cancellation of such SDTB Option and the payment therefor in accordance with the terms of this Agreement.

(v) Subject to the foregoing in this Section 3.09, the SDTB Stock Option Plan and all SDTB Options issued thereunder shall terminate at the Effective Time.

3.10 Reservation of Shares. Prior to the Closing, the PPBI Board shall reserve for issuance a sufficient number of shares of PPBI Common Stock for the purpose of issuing its shares in exchange for shares of SDTB Common Stock in the Merger.

REPRESENTATIONS AND WARRANTIES

5.01 Disclosure Schedules. On or prior to the date hereof, PPBI has delivered to SDTB a schedule and SDTB has delivered to PPBI a schedule (each respectively, its "Disclosure Schedule") setting forth, among other things, items the disclosure of which is necessary or appropriate either in response to an express disclosure requirement contained in a provision hereof or as an exception to one or more representations or warranties contained in Section 5.03 or 5.04 or to one or more of its covenants contained in Articles IV and VI; provided, however, that the mere inclusion of an item in a Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission by a party that such item represents a material exception or fact, event or circumstance or that, absent such inclusion in the Disclosure Schedule, such item is or would be reasonably likely to result in a Material Adverse Effect.

5.02 Standard. Solely for the purposes of determining whether the conditions set forth in Sections 7.02(a) or 7.03(a), as the case may be, have been satisfied (and without otherwise qualifying any representation or warranty made on the date hereof), no representation or warranty of SDTB on the one hand or PPBI on the other hand contained in Sections 5.03 or 5.04, respectively, other than the representations of SDTB contained in Sections 5.03(b) and 5.03(m)(vi), which shall be true in all respects, shall be deemed untrue or incorrect for purposes of Sections 7.02(a) or 7.03(a), and no party hereto shall be deemed to have breached a representation or warranty for purposes of such Sections, as a consequence of the existence of any fact, event or circumstance unless such fact, circumstance or

event, individually or taken together with all other facts, events or circumstances inconsistent with any representation or warranty contained in Section 5.03 or 5.04, has had or is reasonably likely to have a Material Adverse Effect on the party making such representation or warranty.

5.03 Representations and Warranties of SDTB. Subject to Sections 5.01 and 5.02, SDTB hereby represents and warrants to PPBI:

The deposit accounts of SDTB are insured by the FDIC in the manner and to the maximum extent provided by applicable law, and SDTB has paid all deposit insurance premiums and assessments required by applicable laws and regulations.

The minute books of SDTB previously made available to PPBI contain true, complete and correct records in all material respects of all meetings and other material corporate actions held or taken of its shareholders and Board of Directors (including committees of its Board of Directors) through the date hereof; provided that certain records may have been redacted to the extent disclosure of the same: (i) would, upon the advice of counsel, result in the waiver of the privilege protecting communications between SDTB and any of its counsel, (ii) would violate any written confidentiality agreement or similar agreement or arrangement to which SDTB is a party, (iii) would violate any applicable law or regulation, including confidential supervisory information or privacy of customer information, and/or (iv) is information regarding the Transaction that would unduly prejudice SDTB if such information were disclosed to PPBI ("Redacted Information"). Notwithstanding the preceding sentence, SDTB shall use its reasonable best efforts to provide PPBI with substitute disclosure of Redacted Information.

(b) SDTB Capital Stock.

SDTB has performed, in all material respects, all obligations required to be performed by it under each Material Contract.

(ii) Each Benefit Plan has been established and administered to date in all material respects in accordance with the applicable provisions of ERISA, the Code and applicable law and with the terms and provisions of all documents, contracts or agreements pursuant to which such Benefit Plan is maintained. To SDTB's Knowledge, no act or omission has occurred and no condition exists with respect to any Benefit Plan that would subject PPBI or Pacific Premier to any fine, penalty, Tax or liability of any kind imposed under ERISA, the Code or other applicable law following the Closing. Each Benefit Plan which is an "employee pension benefit plan" within the meaning of Section 3(2) of ERISA (a "Pension Plan") and which is intended to be qualified under Section 401(a) of the Code, has received a favorable determination letter, or advisory or opinion letter, as applicable, from the IRS, and SDTB has no Knowledge of any circumstances likely to result in revocation of any such favorable determination letter, or advisory or opinion letter, as applicable, or the loss of the qualification of such Pension Plan under Section 401(a) of the Code. SDTB has not received any correspondence or written or verbal notice from the IRS, DOL or any other Governmental Authority that questions the qualification of any such Benefit Plan. There is no material pending or, to SDTB's Knowledge, threatened litigation relating to the Benefit Plans. SDTB has not engaged in a transaction with respect to any Benefit Plan that would reasonably be expected to subject SDTB to a tax or penalty imposed by either Section 4975 of the Code or Section 502(i) of ERISA in an amount which would be material. To SDTB's Knowledge, there are no matters (other than filings made in the ordinary course) pending before the IRS, DOL or other Governmental Authority with respect to any Benefit Plan. No Benefit Plan or related trust has been the subject of an audit, investigation or examination by a Governmental Authority.

(iii) SDTB does not maintain or contribute to any Pension Plan or multiemployer plan (as defined in 4001(a)(3) of ERISA) other than those disclosed in Section 5.03(m)(iii) of SDTB's Disclosure Schedule. No liability under Title IV of ERISA has been or is reasonably expected to be incurred by SDTB with respect to any ongoing, frozen or terminated "single-employer plan," within the meaning of Section 4001(a)(15) of ERISA, currently or formerly maintained by it or the single-employer plan of any entity which is considered one employer with SDTB under Section 4001 of ERISA or Section 414 of the Code (an "ERISA Affiliate"). SDTB has not incurred, and does not expect to incur, any withdrawal liability with respect to a multiemployer plan under Title IV of ERISA (regardless of whether based on contributions of an ERISA Affiliate). No notice of a "reportable event," within the meaning of Section 4043 of ERISA for which the 30-day reporting requirement has not been waived, has been required to be filed for any Pension Plan or by any ERISA Affiliate or will be required to be filed in connection with the Transaction. There has been no termination, or partial termination, under Section 411(d)(3) of the Code and the regulations thereunder, of any Pension Plan. All ERISA Affiliates of SDTB are set forth (and designated as an ERISA Affiliate) in Section 5.03(m)(iii) of SDTB's Disclosure Schedule.

(iv) All contributions required to be made under the terms of any Benefit Plan have been timely made or have been reflected in the SDTB Financial Statements. Neither any Pension Plan nor any single-employer plan of an ERISA Affiliate has incurred any "unpaid minimum required contribution" within the meaning of Section 4971(c) of the Code and no multiemployer plan has incurred an "accumulated funding deficiency" (whether or not waived)

within the meaning of Section 4971(c) of the Code. SDTB and any of its ERISA Affiliates have met all applicable minimum funding requirements under Section 412 of the Code and Section 302 of ERISA in respect of each Pension Plan and multiemployer plan. Neither SDTB nor any of its ERISA Affiliates have an outstanding funding waiver. The benefit liability, as defined in Section 4001(a)(16) of ERISA, of any Pension Plans subject to Title IV of ERISA, using the actuarial assumptions that would be used by the PBGC in the event such Pension Plan is terminated, does not exceed the fair market value of the assets of each such plan. The liabilities of each such terminated Pension Plan have been fully discharged in full compliance with applicable laws.

(v) Neither SDTB nor any of its ERISA Affiliates have any obligations for retiree health and life benefits under any Benefit Plan, other than coverage as may be required under Section 4980B of the Code or Part 6 of Title I of ERISA, or under the continuation of coverage provisions of the laws of any state or locality. SDTB may amend or terminate any such Benefit Plan in accordance with and to the extent permitted by its terms at any time without incurring any liability thereunder other than payment of benefits provided for thereunder and expenses associated with accomplishing such amendment or termination. No event or condition exists with respect to a Benefit Plan that could subject SDTB to a material Tax under Section 4980B of the Code.

(vi) Except as set forth in Section 5.03(m)(vi) of SDTB's Disclosure Schedule, SDTB is not a party to any contract that will, as a consequence of the execution of this Agreement, shareholder approval of this Agreement or consummation of the Transaction, either alone or in connection with any other event, (A) entitle any Employees or any current or former director or independent contractor of SDTB to severance pay or any increase in severance pay upon any termination of employment after the date hereof, (B) accelerate the time of payment or vesting or trigger any payment or funding (through a grantor trust or otherwise) of compensation or benefits under, increase the amount payable under, or trigger any other material obligation pursuant to, any of the Benefit Plans, (C) result in any breach or violation of, or a default under, any of the Benefit Plans or (D) result in the payment of any "excess parachute payments" within the meaning of Section 280G of the Code.

(vii) Except as set forth in Section 5.03(m)(vii) of SDTB's Disclosure Schedule, all required reports and descriptions (including but not limited to Form 5500 annual reports and required attachments, Forms 1099-R, summary annual reports, Forms PBGC-1 and summary plan descriptions) have been filed or distributed appropriately with respect to each Benefit Plan. All required Tax filings with respect to each Benefit Plan have been made, and any Taxes due in connection with such filings have been paid.

(viii) SDTB does not have now, nor has had, the obligation to maintain, establish, sponsor, participate in or contribute to any Benefit Plan or other similar arrangement that is subject to any law or applicable custom or rule of any jurisdiction outside of the United States.

(ix) No Benefit Plan is or has been funded by, associated with, or related to a "voluntary employee's beneficiary association" within the meaning of Section 501(c)(9) of the Code, a "welfare benefit fund" within the meaning of Section 419 of the Code, a "qualified asset account" within the meaning of Section 419A of the Code or a "multiple employer welfare arrangement" within the meaning of Section 3(40) of ERISA.

(x) Each Benefit Plan which is a "nonqualified deferred compensation plan" (within the meaning of Section 409A of the Code) has been operated in compliance with Section 409A of the Code.

(xi) No contributions pursuant to a Benefit Plan have been made by SDTB in such amounts that would violate Section 404 of the Code.

(xii) SDTB has in force sufficient bonding for every fiduciary who is or has been required to be bonded with respect to the Benefit Plans. There does not exist any pending or, to SDTB's Knowledge, threatened legal proceedings (other than routine claims for benefits), arbitrations, administrative or other proceeding with respect to any Benefit Plan or any related trust or other funding medium thereunder or with respect to SDTB as the sponsor or fiduciary thereof, or to SDTB's Knowledge, with respect to any other fiduciary thereof.

(xiii) Section 5.03(m)(xiii) of SDTB's Disclosure Schedule sets forth the following for each individual employed by SDTB to whom it would apply: (A) the maximum amount of all payments and benefits to which such individual is entitled to receive, pursuant to all employment, salary continuation, bonus, change in control, and all other agreements, plans and arrangements of SDTB, in connection with a termination of employment before or following, or otherwise in connection with or contingent upon, the consummation of the Transaction (each such total amount in respect of each such individual, the "Change in Control Benefit"), other than the payment any such individual shall otherwise be entitled to receive as a gross-up payment in respect of any excise Tax imposed on the individual pursuant to Section 4999 of the Code as calculated pursuant to the applicable agreement (each such payment, a "Gross-Up Payment"); (B) the amount of any Gross-Up Payment payable to each such individual; and (C) the maximum aggregate amount of all Change in Control Benefits and Gross-Up Payments.

(n) Labor Matters.

(ii) To SDTB's Knowledge, no officer or director of SDTB or any employee, independent contractor or consultant of SDTB is a party to, or is otherwise bound by, any agreement or arrangement, including any confidentiality, non-competition, or proprietary rights agreement, that could materially and adversely affect the ability of SDTB to conduct its business as currently conducted.

(ii) Since September 30, 2012, no event has occurred or circumstance arisen that, individually or taken together with all other facts, circumstances and events (described in any paragraph of this Section 5.04 or otherwise), is reasonably likely to have a Material Adverse Effect with respect to PPBI.

(h) Legal Proceedings. No litigation, arbitration, claim or other proceeding before any court or governmental agency is pending against PPBI or its Subsidiaries and, to PPBI's Knowledge, no such litigation, arbitration, claim or other proceeding has been threatened and there are no facts which could reasonably give rise to such litigation, arbitration, claim or other proceeding in any such case that, individually or in the aggregate, has or could be reasonably expected to have a Material Adverse Effect with respect to PPBI.

(j) Regulatory Matters.

(i) Since January 1, 2012, PPBI and each of its Subsidiaries has duly filed with the appropriate bank regulatory authorities in substantially correct form the monthly, quarterly and annual reports required to be filed under applicable laws and regulations, and such reports were in all material respects complete and accurate and in compliance with the requirements of applicable laws and regulations. In connection with the most recent examination of PPBI and each of its Subsidiaries by the appropriate regulatory authorities, neither PPBI nor any of its Subsidiaries was required to correct or change any action, procedure or proceeding which PPBI believes in good faith has not now been corrected or changed, other than corrections or changes which, if not made, either individually or in the

PPBI and its Subsidiaries have paid all assessments made or imposed by any Governmental Authority.

(iii) Neither PPBI nor any its Subsidiaries has been advised by, and does not have any Knowledge of facts which would reasonably be expected to give rise to an advisory notice by, any Governmental Authority that such Governmental Authority is contemplating issuing or requesting (or is considering the appropriateness of issuing or requesting) any such order, decree, directive, agreement, memorandum of understanding, commitment letter, supervisory letter or similar submission or any request for the adoption of any policy, procedure or board resolution.

(iv) (A) No Governmental Authority has initiated since December 31, 2010 or has pending any proceeding, enforcement action or, to PPBI's Knowledge, investigation or inquiry into the business, operations, policies, practices or disclosures of PPBI or any of its Subsidiaries (other than normal examinations conducted by a Governmental Authority in the ordinary course of the business of PPBI or the applicable Subsidiary), or, to PPBI's Knowledge, threatened any of the foregoing, and (B) there is no unresolved violation, criticism, comment or exception by any Governmental Authority with respect to any report or statement relating to any examinations or inspections of PPBI or its Subsidiaries, except in each case in subparagraphs (A) and (B), that did not have a Material Adverse Effect.

(v) PPBI and Pacific Premier are "well-capitalized" (as that term is defined at 12 CFR §225.2(r) or the relevant regulation of its primary federal bank regulator) and the rating of Pacific Premier under the CRA is no less than "satisfactory." Neither PPBI nor Pacific Premier has received any notification from a Governmental Authority that their status as "well-capitalized" or "satisfactory" for CRA purposes will change within one year, nor does PPBI have knowledge of any conditions or circumstances that would result in a CRA rating of less than "satisfactory" or material criticism from regulators with respect to discriminatory lending practices.

(vi) PPBI has sufficient capital and liquidity to complete the Merger and fund the cash portion of the Merger Consideration.

(k) Compliance With Laws. Each of PPBI and its Subsidiaries:

(ii) has all permits, licenses, franchises, authorizations, orders and approvals of, and has made all filings, applications and registrations with, all Governmental Authorities that are required in order to permit them to own or lease their properties and to conduct their businesses as presently conducted; all such permits, licenses, certificates of authority, orders and approvals are in full force and effect and, to PPBI's Knowledge, no suspension or cancellation of any of them is threatened; and

(iii) has received no notification or communication from any Governmental Authority (A) asserting that PPBI or any of its Subsidiaries is not in compliance with any of the statutes, regulations or ordinances which such Governmental Authority enforces or (B) threatening to revoke any license, franchise, permit or governmental authorization (nor, to PPBI's Knowledge, do any grounds for any of the foregoing exist).

(l) Ownership of SDTB Common Stock. None of PPBI or any of its Subsidiaries, or to PPBI's Knowledge, any of its other affiliates or associates (as such terms are defined under the Exchange Act), owns beneficially or of record, directly or indirectly, or is a party to any agreement, arrangement or understanding for the purpose of acquiring, holding, voting or disposing of, shares of SDTB Common Stock (other than shares held in a fiduciary capacity that are beneficially owned by third parties or as a result of debts previously contracted).

(m) Financial Ability. PPBI has all funds necessary to consummate the Merger and pay the Merger Consideration to holders of SDTB Common Stock pursuant to Sections 3.01 and 3.03 hereof.

(n) Absence of Certain Changes or Events. Since January 1, 2012, except as specifically contemplated by or as disclosed in this Agreement or otherwise disclosed in PPBI's public filings with the SEC, there has not been any Material Adverse Effect with respect to PPBI or any event or development that is reasonably expect to have, either individually or in the aggregate, a Material Adverse Effect with respect to PPBI.

(o) Disclosure. The representations and warranties contained in this Section 5.04, when considered as a whole, do not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements and information contained in this Section 5.04 not misleading.

shareholders for consummation of the Transaction (including any adjournment or postponement, the "SDTB Meeting"). Except with the prior approval of PPBI, no other matters shall be submitted for the approval of the SDTB shareholders at the SDTB Meeting. Subject to Section 6.02(b), the SDTB Board shall at all times prior to and during such meeting recommend such approval and shall take all reasonable lawful action to solicit such approval by its shareholders and shall not (x) withdraw, modify or qualify in any manner adverse to PPBI such recommendation or (y) take any other action or make any other public statement in connection with the SDTB Meeting inconsistent with such recommendation (collectively, a "Change in Recommendation"), except as and to the extent permitted by Section 6.02(b). Notwithstanding any Change in Recommendation, this Agreement shall be submitted to the shareholders of SDTB at the SDTB Meeting for the purpose of approving the Agreement and any other matters required to be approved by SDTB's shareholders for consummation of the Transaction. In addition to the foregoing, SDTB shall not submit to the vote of its shareholders any Acquisition Proposal other than the Merger.

(i) SDTB shall have complied in all material respects with Section 6.07;

(ii) the SDTB Board, based on advice of its outside counsel, shall have determined in good faith that failure to do so would result in a violation of its fiduciary duties under applicable law; and

(iii) if the SDTB Board intends to effect a Change in Recommendation following an Acquisition Proposal, (A) the SDTB Board shall have concluded in good faith, after giving effect to all of the adjustments which may be offered by PPBI pursuant to clause (C) below, that such Acquisition Proposal constitutes a Superior Proposal, (B) SDTB shall notify PPBI, at least five Business Days in advance, of its intention to effect a Change in Recommendation in response to such Superior Proposal (including the identity of the party making such Acquisition Proposal) and furnish to PPBI a copy of the relevant proposed transaction agreements with the party making such Superior Proposal and all other material documents, and (C) prior to effecting such a Change in Recommendation, SDTB shall, and shall cause its financial and legal advisors to, during the period following SDTB's delivery of the notice referred to in clause (B) above, negotiate with PPBI in good faith for a period of up to five Business Days (to the extent PPBI desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such Acquisition Proposal ceases to constitute a Superior Proposal.

(a) PPBI agrees to prepare a registration statement on Form S-4 or other applicable form (the "Registration Statement") to be filed by PPBI with the SEC in connection with the issuance of the shares of PPBI Common Stock to the SDTB shareholders as part of the Merger Consideration in the Merger (including the proxy statement for the SDTB Meeting and prospectus and other proxy solicitation materials of SDTB constituting a part thereof (the "Proxy Statement") and all related documents). SDTB shall prepare and furnish such information relating to it and its directors, officers and shareholders and SDTB's business and operations as may be reasonably required or otherwise necessary to comply with SEC rules and regulations or SEC staff comments in connection with the Registration Statement, which information may be based on its knowledge of and access to the information required for said documents and advice of counsel with respect to SEC disclosure obligations. PPBI shall provide SDTB and its legal, financial and accounting advisors the opportunity to: (i) review and provide comments upon such Registration Statement a reasonable time prior to its filing and (ii) review and provide comments on all amendments and

supplements to the Registration Statement and all responses to requests for additional information and replies to comments relating to the Registration Statement a reasonable time prior to filing or submission to the SEC. PPBI shall consider in good faith all comments from SDTB and its legal, financial and accounting advisors to the Registration Statement, all amendments and supplements thereto and all responses to requests for additional information, and shall not include any information in the foregoing about SDTB or its officers, directors, business, arrangements, operations or stock that has not been approved by SDTB, which approval shall not be unreasonably withheld, delayed or conditioned. SDTB agrees to cooperate with PPBI and PPBI's counsel and accountants in requesting and obtaining appropriate opinions, consents, analyses and letters from its financial advisor and independent auditor in connection with the Registration Statement and the Proxy Statement.

Each of SDTB and PPBI further agrees that if such party shall become aware prior to the date of effectiveness of the Registration Statement of any information furnished by such party that would cause any of the statements in the Registration Statement or the Proxy Statement to be false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements therein not false or misleading, to promptly inform the other parties thereof and to take the necessary steps to correct the Registration Statement or the Proxy Statement.

(c) PPBI agrees to advise SDTB, promptly after PPBI receives notice thereof, of the time when the Registration Statement has become effective or any supplement or amendment has been filed, of the issuance of any stop order or the suspension of the qualification of PPBI Common Stock for offering or sale in any jurisdiction, of the initiation or, to the extent PPBI is aware thereof, threat of any proceeding for any such purpose, of any request by the SEC for the amendment or supplement of the Registration Statement or for additional information or of any other correspondence from the SEC in connection with the Registration Statement that relates to SDTB or the Transaction. PPBI agrees to promptly provide to SDTB copies of correspondence between PPBI (or any of its representatives and advisors on PPBI's behalf), on the one hand, and the SEC, on the other hand as to relates to the Registration Statement or the Transaction.

(a) SDTB agrees that it shall, and shall direct and use its reasonable best efforts to cause its affiliates, directors, officers, employees, agents and representatives (including, without limitation, any investment banker, financial advisor, attorney, accountant or other representative retained by it) (all of the foregoing, collectively, "Representatives") to, immediately cease any discussions or negotiations with any other parties that may be ongoing with respect to the possibility or consideration of any Acquisition Proposal (as defined below), and will use its reasonable best efforts to enforce any confidentiality or similar agreement relating to any Acquisition Proposal, including by requesting the other party to promptly return or destroy any confidential information previously furnished by or on behalf of SDTB thereunder and by specifically enforcing the terms thereof in a court of competent jurisdiction. From the date of this Agreement through the Effective Time, SDTB shall not, and shall cause its directors, officers or employees or any Representative retained by it not to, directly or indirectly through another Person, (i) solicit, initiate or encourage (including by way of furnishing information or assistance), or take any other action designed to facilitate or that is likely to result in, any inquiries or the making of any proposal or offer that constitutes, or is reasonably likely to lead to, any Acquisition Proposal, (ii) provide any confidential information or data to any Person relating to any Acquisition Proposal, (iii) participate in any discussions or negotiations regarding any Acquisition Proposal, (iv) waive, terminate, modify or fail to enforce any provision of any contractual "standstill" or similar obligations of any Person other than PPBI or its Affiliates, (v) approve or recommend, propose to approve or recommend, or execute or enter into, any letter of intent, agreement in principle, merger agreement, asset purchase agreement or share exchange agreement, option agreement or other similar agreement related to any Acquisition Proposal or propose to do any of

the foregoing, or (vi) make or authorize any statement, recommendation or solicitation in support of any Acquisition Proposal; provided, however, that prior to the date of the SDTB Meeting, if the SDTB Board determines in good faith, after consulting with its outside legal and financial advisors, that the failure to do so would breach, or would reasonably be expected to result in a breach of, the SDTB Board's fiduciary duties under applicable law, SDTB may, in response to a bona fide, written Acquisition Proposal not solicited in violation of this Section 6.07(a) that the SDTB Board determines in good faith constitutes a Superior Proposal (as defined below), subject to providing 48 hour prior written notice of its decision to take such action to PPBI and identifying the Person making the proposal and all the material terms and conditions of such proposal and compliance with Section 6.07(b), (1) furnish information with respect to itself to any Person making such a Superior Proposal pursuant to a customary confidentiality agreement (as determined by SDTB after consultation with its outside counsel) on terms no more favorable to such Person than the terms contained in the Confidentiality Agreement are to PPBI, and (2) participate in discussions or negotiations regarding such a Superior Proposal. For purposes of this Agreement, the term "Acquisition Proposal" means any inquiry, proposal or offer, filing of any regulatory application or notice (whether in draft or final form) or disclosure of an intention to do any of the foregoing from any Person relating to any (w) direct or indirect acquisition or purchase of a business that constitutes 10% or more of the total revenues, net income, assets or deposits of SDTB, (x) direct or indirect acquisition or purchase of any class of Equity Securities representing 10% or more of the voting power of SDTB, (y) tender offer or exchange offer that if consummated would result in any person beneficially owning 10% or more of any class of Equity Securities of SDTB or (z) merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving SDTB, other than the Transaction contemplated by this Agreement. For purposes of this Agreement, the term "Superior Proposal" means any bona fide written proposal made by a third party to acquire, directly or indirectly, including pursuant to a tender offer, exchange offer, merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction, for consideration consisting of cash and/or securities, more than 50% of the combined voting power of the shares of SDTB Common Stock then outstanding or all or substantially all of SDTB's consolidated assets, which the SDTB Board determines in good faith, after taking into account all legal, financial, regulatory and other aspects of the proposal and the person making the proposal (including any break-up fees, expense reimbursement provisions and conditions to consummation), and after taking into account the advice of SDTB's financial advisor (which shall be a nationally recognized investment banking firm) and outside counsel, (i) is more favorable from a financial point of view to its shareholders than the Merger, (ii) is reasonably likely to be consummated on the terms set forth, and (iii) for which financing, to the extent required, is then committed or which, in the good faith judgment of the SDTB Board, is reasonably likely to be obtained by such third party.

(b) In addition to the obligations of SDTB set forth in Section 6.07(a), SDTB shall promptly (within 24 hours) advise PPBI orally and in writing of its receipt of any Acquisition Proposal (or any inquiry which could reasonably be expected to lead to an Acquisition Proposal) and keep PPBI informed, on a current basis, of the continuing status thereof, including the terms and conditions thereof and any changes thereto, and shall contemporaneously provide to PPBI all materials provided to or made available to any third party pursuant to this Section 6.07 which were not previously provided to PPBI.

(c) SDTB agrees that any violation of the restrictions set forth in this Section 6.07 by any Representative of SDTB shall be deemed a breach of this Section 6.07 by SDTB.

(d) The parties hereto agree that irreparable damage would occur in the event any of the restrictions set forth in Section 6.07(a) were violated by SDTB or any Representative of SDTB. It is accordingly agreed that PPBI shall be entitled to an injunction or injunctions to prevent

breaches of Section 6.07 and to enforce specifically the terms and provisions thereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which PPBI is entitled at law or in equity. In the event attorneys' fees or other costs are incurred to secure performance of any of the obligations herein provided for, or to establish damages for the breach thereof, or to obtain any other appropriate relief, whether by way of prosecution or defense, PPBI shall be entitled to recover reasonable attorneys' fees and costs incurred therein.

(e) Nothing contained in this Section 6.07 shall prevent SDTB or the SDTB Board from (i) taking the actions provided in Section 6.02(b) of this Agreement, (ii) responding to an unsolicited bone fide Acquisition Proposal for the sole purpose of clarifying the terms and conditions of the Acquisition Proposal, (iii) informing any Person who submits an unsolicited bone fide Acquisition Proposal of SDTB's obligations pursuant to this Section 6.07 or (iv) with the advice of outside counsel, complying with its disclosure obligations under federal or state law in connection with a Change in Recommendation that occurs pursuant to Section 6.02(b).

6.08 Certain Policies. Prior to the Effective Date, upon the request of PPBI, SDTB shall, consistent with GAAP and applicable banking laws and regulations, use its reasonable best efforts to modify or change its Loan, OREO, accrual, reserve, Tax, litigation and real estate valuation policies and practices (including loan classifications and levels of reserves) so as to be applied on a basis that is consistent with that of PPBI; provided, however, that no such modifications or changes need be made prior to the satisfaction of the conditions set forth in Section 7.01(b); and further provided that in any event, no such modification or change made by SDTB pursuant to this Section 6.08 shall constitute or be deemed to be a breach, violation of or failure to satisfy any representation, warranty, covenant, agreement, condition or other provision of this Agreement or otherwise be considered in determining whether any such breach, violation or failure to satisfy shall have occurred. The recording of any such adjustments shall not be deemed to imply any misstatement of previously furnished financial statements or information and shall not be construed as concurrence of SDTB or its management with any such adjustments.

6.09 Nasdaq Listing. PPBI shall, as promptly as practicable, file all documents, take all actions reasonably necessary and otherwise use its reasonable best efforts to list, prior to the Effective Date, on the Nasdaq the shares of PPBI Common Stock to be issued to the SDTB shareholders as part of the Merger Consideration in connection with the Merger.

6.10 Indemnification.

(a) From and after the Effective Time through the sixth anniversary of the Effective Time, PPBI (the "Indemnifying Party") shall indemnify and hold harmless each present and former director, officer and employee of SDTB, determined as of the Effective Time, and each of their heirs and estates (the "Indemnified Parties") against any costs or expenses (including reasonable attorneys' fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of matters existing or occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, arising in whole or in part out of or pertaining to the fact that he or she was a director, officer, employee, fiduciary or agent of SDTB or is or was serving at the request of SDTB as a director, officer, employee, fiduciary or agent of another corporation, partnership, joint venture, trust or other enterprise, including, without limitation, matters related to the negotiation, execution and performance of this Agreement or consummation of the Transaction, to the fullest extent which such Indemnified Parties would be entitled under the SDTB Articles and the SDTB Bylaws or any agreement, arrangement or understanding which has been set forth in Section 6.10 of SDTB's Disclosure Schedule, in each case as in effect on the date hereof.

(b) Any Indemnified Party wishing to claim indemnification under this Section 6.10, upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify the Indemnifying Party, but the failure to so notify shall not relieve the Indemnifying Party of any liability it may have to such Indemnified Party if such failure does not actually prejudice the Indemnifying Party. In the event of any such claim, action, suit, proceeding or investigation (whether arising before or after the Effective Time), (i) the Indemnifying Party shall have the right to assume the defense thereof and the Indemnifying Party shall not be liable to such Indemnified Parties for any legal expenses of other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense thereof, except that if the Indemnifying Party elects not to assume such defense or counsel for the Indemnified Parties advises that there are issues which raise conflicts of interest between the Indemnifying Party and the Indemnified Parties that make joint representation inappropriate, the Indemnified Parties may retain counsel which is reasonably satisfactory to the Indemnifying Party, and the Indemnifying Party shall pay, promptly as statements therefor are received, the reasonable fees and expenses of such counsel for the Indemnified Parties (which may not exceed one firm in any jurisdiction unless the Indemnified Parties have conflicts of interest), (ii) the Indemnified Parties will cooperate in the defense of any such matter, (iii) the Indemnifying Party shall not be liable for any settlement effected without its prior written consent, which shall not be unreasonably withheld, and (iv) the Indemnifying Party shall have no obligation hereunder in the event that a federal or state banking agency or a court of competent jurisdiction shall determine that indemnification of an Indemnified Party in the manner contemplated hereby is prohibited by applicable laws and regulations.

(c) PPBI shall permit SDTB to obtain, and thereafter shall maintain, "tail" liability insurance, which shall provide for a period of three (3) years after the Effective Time, to persons who are currently covered by SDTB's existing directors' and officers' liability insurance policy, at least the same coverage and amounts, and contain terms and conditions no less advantageous, as that coverage currently provided by SDTB, including all additional liability coverage that serves to provide coverage to or reimburse SDTB's present and former directors and/or officers; provided, however, that if the cost of such insurance is in excess of 200% of the annual premiums paid by SDTB as of the date hereof for SDTB's current directors' and officers' liability insurance ("Maximum Insurance Amount"), SDTB, at its discretion, shall either obtain (i) such insurance, with the excess cost and expense above the Maximum Insurance Amount being considered a Deal Expense as set forth in Section 9.05, or (ii) the most advantageous coverage obtainable for an annual premium equal to the Maximum Insurance Amount.

(d) If PPBI or any of its successors or assigns shall consolidate with or merge into any other entity and shall not be the continuing or surviving entity of such consolidation or merger or shall transfer all or substantially all of its assets to any other entity, then and in each case, proper provision shall be made so that the successors and assigns of PPBI shall assume the obligations set forth in this Section 6.10.

6.11 Benefit Plans.

(a) As soon as administratively practicable after the Effective Time, PPBI shall take all reasonable action so that employees of SDTB shall be entitled to participate in each employee benefit plan, program or arrangement of PPBI and Pacific Premier of general applicability (the "PPBI Benefit Plans") to the same extent as similarly-situated employees of PPBI and its Subsidiaries (it being understood that inclusion of the employees of SDTB in the PPBI Benefit Plans may occur at different times with respect to different plans), provided that coverage shall be continued under the corresponding Benefit Plans of SDTB until such employees are permitted to participate in the PPBI Benefit Plans and provided further, however, that nothing contained herein shall require PPBI or any of its Subsidiaries to make any grants to any former employee of SDTB under any discretionary equity compensation plan of PPBI. PPBI shall cause each PPBI Benefit

Plan in which employees of SDTB are eligible to participate to recognize, for purposes of determining eligibility to participate in, the vesting of benefits and for all other purposes (but not for accrual of pension benefits) under the PPBI Benefit Plans, the service of such employees with SDTB to the same extent as such service was credited for such purpose by SDTB, provided, however, that such service shall not be recognized to the extent that such recognition would result in a duplication of benefits. Nothing herein shall limit the ability of PPBI to amend or terminate any of SDTB's Benefit Plans in accordance with their terms at any time.

(b) At and following the Effective Time, PPBI shall honor, and the Surviving Bank shall continue to be obligated to perform, in accordance with their terms, all benefit obligations to, and contractual rights of, current and former employees of SDTB and current and former directors of SDTB existing as of the Effective Date, as well as all bonus deferred compensation or other existing plans and policies of SDTB to the extent that each of the foregoing are Previously Disclosed. The severance or termination payments which are payable pursuant to such agreements, plans or policies of SDTB (which have been quantified in reasonable detail) have been Previously Disclosed. Each current or former SDTB director or executive officer that will receive payments pursuant to any SDTB deferred compensation plan, supplemental employee retirement plan or other deferred compensation arrangement as of and/or after the Effective Time shall enter into a release agreement with PPBI no later than the Effective Time that provides for such SDTB director or executive officer to confirm and agree to the payments that he or she is entitled to receive under such plan (which payments shall be specifically set forth in such release agreement) as of and/or after the Effective Time; provided that such release agreement, and the director's or executive's execution thereof, shall not change the time and form of payment due under the plan or arrangement in a manner that would violate Code Section 409A.

(c) At such time as employees of SDTB become eligible to participate in a medical, dental or health plan of PPBI or its Subsidiaries, PPBI shall cause each such plan to (i) waive any preexisting condition limitations to the extent such conditions covered under the applicable medical, health or dental plans of PPBI, (ii) provide full credit under such plans for any deductibles, co-payment and out-of-pocket expenses incurred by the employees and their beneficiaries during the portion of the calendar year prior to such participation and (iii) waive any waiting period limitation or evidence of insurability requirement which would otherwise be applicable to such employee on or after the Effective Time to the extent such employee had satisfied any similar limitation or requirement under an analogous Plan prior to the Effective Time.

(d) Those employees of SDTB who are not offered employment by PPBI or its Subsidiaries following the Effective Time, who are not a party to an employment agreement or otherwise entitled to an existing severance package and who sign and deliver a termination and release agreement (which will be negotiated between PPBI and SDTB) within 30 days of the Effective Time shall be entitled to receive a single lump sum payment of severance equal to two weeks of salary for each year of service (with a prorated amount of payment for partial years), up to a maximum of 13 weeks. Such payments will be made by PPBI on the date the termination and release agreement that is executed by an employee becomes effective, which date shall be in the sole discretion of PPBI. If SDTB also has a severance pay plan, then any amounts paid pursuant to that plan shall reduce the amount that the employee will receive under this Section 6.11(d) and in no event shall there be any duplication of severance pay. Nothing contained in this Section 6.11(d) hereof shall be construed or interpreted to limit or modify in any way PPBI's or its Subsidiaries at will employment policy or provide any third party beneficiary rights to employees of SDTB. In no event shall severance pay be taken into account in determining the amount of any other benefit (including but not limited to, an individual's benefit under any retirement plan or policy). If, by reason of the controlling plan document, controlling law or otherwise, severance pay is taken into account in determining any other benefit, the severance pay otherwise payable shall be reduced by the present value of the additional benefit determined under other benefit plans attributable to the severance pay period.

(e) Each of SDTB, PPBI and Pacific Premier acknowledges and agrees that all provisions contained within this Section 6.11 with respect to Employees are included for the sole benefit of SDTB and PPBI and shall not create any right (i) in any other Person, including, Benefit Plans or any beneficiary thereof or (ii) to continued employment with SDTB, PPBI or any of its Subsidiaries.

6.12 Employment and Non-Competition Agreements. As of the date of this Agreement, (a) ▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇ has entered into an employment agreement ("Employment Agreement") with Pacific Premier, which shall be effective as of the Closing Date and with the terms and in the form which is set forth in Annex D hereto (and such Employment Agreement shall supersede and replace ▇▇. ▇▇▇▇▇▇▇'▇ current employment agreement with SDTB, which shall be cancelled and have no further force and effect) and (b) ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇ has entered into a confidentiality, noncompetition and non-solicitation agreement ("Noncompetition Agreement") with Pacific Premier, which shall be effective as of the Closing Date and with the terms and in the form which is set forth in Annex E hereto.

6.13 Notification of Certain Matters. Each of SDTB, PPBI and Pacific Premier shall 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.

6.14 Estoppel Letters. SDTB shall use its commercially reasonable efforts to obtain and deliver to PPBI at the Closing with respect to the real estate leased by SDTB, an estoppel letter dated as of the Closing in substantially the form of Annex C from its lessor.

6.15 Antitakeover Statutes. Each of PPBI and SDTB and their respective Boards of Directors shall, if any state antitakeover statute or similar statute becomes applicable to this Agreement and the Transaction, take all action reasonably necessary to ensure that the Transaction may be consummated as promptly as practicable on the terms contemplated hereby and otherwise to minimize the effect of such statute or regulation on this Agreement and the Transaction.

(a) Mutual Consent. By the mutual consent in writing of PPBI, Pacific Premier and SDTB.

(b) Breach. Provided that the terminating party is not then in material breach of any representation, warranty, covenant or agreement contained herein, by PPBI and Pacific Premier on the one hand or SDTB on the other hand, in the event of a breach by the other party or parties of any representation, warranty, covenant or agreement contained herein, which breach (i) cannot be or has not been cured within 30 days after the giving of written notice to the breaching party or parties of such breach and (ii) would entitle the non-breaching party or parties not to consummate

the Transaction contemplated hereby under Section 7.02(a) or (b) or 7.03(a) or (b), as the case may be.

(c) Delay. Except to the extent that the failure of the Merger then to be consummated by such date shall be due to (i) the failure of the party seeking to terminate pursuant to this Section 8.01(c) to perform or observe the covenants and agreements of such party or parties set forth in this Agreement or (ii) the failure of any of the Shareholders (if SDTB is the party seeking to terminate) to perform or observe their respective covenants and agreements under the relevant Shareholder Agreement, by PPBI and Pacific Premier on the one hand or SDTB on the other hand, in the event that the Merger is not consummated by September 30, 2013.

(d) No Regulatory Approval. By PPBI and Pacific Premier on the one hand or SDTB on the other hand in the event the approval of any Governmental Authority required for consummation of the Merger and the other transactions contemplated by this Agreement shall have been denied by final nonappealable action of such Governmental Authority or an application therefor shall have been permanently withdrawn at the request of a Governmental Authority, provided, however, that no party or parties shall have the right to terminate this Agreement pursuant to this Section 8.01(d) if such denial shall be due to the failure of the party or parties seeking to terminate this Agreement to perform or observe the covenants of such party or parties set forth herein.

(e) No SDTB Shareholder Approval. By PPBI and Pacific Premier on the one hand or SDTB on the other hand, if the approval of the shareholders of SDTB contemplated by this Agreement shall not have been obtained by reason of the failure to obtain the required vote at the SDTB Meeting or at any adjournment or postponement thereof.

(g) Certain Tender or Exchange Offers.

8.02 Effect of Termination and Abandonment.

(a) In the event of termination of this Agreement and the abandonment of the Merger pursuant to this Article VIII, no party to this Agreement shall have any liability or further obligation to any other party hereunder except that (i) this Section 8.02, Section 6.06(c) and Article IX shall survive any termination of this Agreement and (ii) notwithstanding anything to the contrary, neither PPBI nor SDTB shall be relieved or released from any liabilities or damages arising out of its fraud or willful breach of any provision of this Agreement.

(b) The parties hereto agree that SDTB shall pay PPBI the sum of $1.75 million (the "Termination Fee") if this Agreement is terminated as follows, it being understood that in no event shall SDTB be required to pay the Termination Fee on more than one occasion:

(i) if this Agreement is terminated by PPBI pursuant to Section 8.01(f) or (g), SDTB shall pay the entire Termination Fee to PPBI on the second Business Day following the termination of this Agreement; or

(ii) if this Agreement is terminated by (A) PPBI pursuant to Section 8.01(b), (B) by either PPBI or SDTB pursuant to Section 8.01(c) and at the time of such termination no vote of the SDTB shareholders contemplated by this Agreement at the SDTB Meeting shall have occurred, or (C) by either PPBI or SDTB pursuant to Section 8.01(e), and in the case of any termination pursuant to clause (A), (B) or (C), an Acquisition Proposal shall have been publicly announced or otherwise communicated or made known to the senior management of SDTB or the SDTB Board (or any Person shall have publicly announced, communicated or made known an intention, whether or not conditional, to make an Acquisition Proposal, or reiterated a previously expressed plan or intention to make an Acquisition Proposal) at any time after the date of this Agreement and prior to the taking of the vote of the shareholders of SDTB contemplated by this Agreement at the SDTB Meeting, in the case of clause (C), or the date of termination, in the case of clause (A) or (B), then (1) if within 12 months after such termination SDTB enters into an agreement with respect to a Control Transaction, then SDTB shall pay to PPBI an amount equal to $1.0 million on the date of execution of such agreement and upon consummation of any such Control Transaction at any time thereafter, SDTB shall pay to PPBI the remainder of the Termination Fee on the date of such consummation and (2) if a Control Transaction is consummated otherwise than pursuant to an agreement with SDTB within 15 months after such termination, then SDTB shall pay to PPBI the Termination Fee (less any amount previously paid by SDTB pursuant to clause (1) above) on the date of such consummation of such Control Transaction. As used in this Section 8.02(b), a "Control Transaction" means (i) the acquisition by any Person whether by purchase, merger, consolidation, sale, transfer or otherwise, in one transaction or any series of transactions, of a majority of the voting power of the outstanding securities of SDTB or a majority of the assets of SDTB, (ii) any issuance of securities resulting in the ownership by any Person of more than 50% of the voting power of SDTB or by any Person other than SDTB of more than 50% of the voting power of SDTB or (iii) any merger, consolidation or other business combination transaction involving SDTB as a result of which the shareholders of SDTB cease to own, in the aggregate, at least 50% of the total voting power of the entity surviving or resulting from such transaction.

Any amount that becomes payable pursuant to this Section 8.02(b) shall be paid by wire transfer of immediately available funds to an account designated by PPBI. To the extent fully paid in accordance with this Section 8.02, the payment of a Termination Fee shall be the sole and exclusive remedy of PPBI, Pacific Premier and each of their affiliates and representatives for damages against SDTB with respect to or arising out of this Agreement or the Transaction contemplated thereby.

(c) SDTB and PPBI agree that the agreement contained in paragraph (b) above is an integral part of the transactions contemplated by this Agreement, that without such agreement PPBI would not have entered into this Agreement, and that such amounts do not constitute a penalty or liquidated damages in the event of a breach of this Agreement by SDTB. If SDTB fails to pay PPBI the amounts due under paragraph (b) above within the time periods specified in such paragraph (b), SDTB shall pay the costs and expenses (including reasonable legal fees and expenses) incurred by PPBI in connection with any action, including the filing of any lawsuit, taken to collect payment of such amounts, provided PPBI prevails on the merits, together with interest on the amount of any such unpaid amounts at the prime lending rate prevailing during such period as published in The Wall Street Journal, calculated on a daily basis from the date such amounts were required to be paid until the date of actual payment.

ARTICLE IX

MISCELLANEOUS

9.01 Survival. No representations, warranties, agreements and covenants contained in this Agreement shall survive the Effective Time (other than agreements or covenants contained herein that by their express terms are to be performed after the Effective Time) or the termination of this Agreement if this Agreement is terminated prior to the Effective Time (other than Sections 6.06(c), 8.02 and this Article IX, which shall survive any such termination). Notwithstanding anything in the foregoing to the contrary, no representations, warranties, agreements and covenants contained in this Agreement shall be deemed to be terminated or extinguished so as to deprive a party hereto or any of its affiliates of any defense at law or in equity which otherwise would be available against the claims of any Person, including without limitation any shareholder or former shareholder.

9.02 Waiver; Amendment. Prior to the Effective Time, any provision of this Agreement may be (i) waived, by the party benefited by the provision 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, except that after the approval of the principal terms of this Agreement by the SDTB shareholders, no amendment shall be made which by law requires further approval by the shareholders of SDTB without obtaining such approval. For purposes of clarification, an amendment of any date in Section 8.01(c) shall not require further approval by any shareholders and if such amendment were deemed by law to require further approval by the shareholders of SDTB, the approval of the principal terms of this Agreement by the SDTB shareholders will be deemed to have granted SDTB the authority to amend such dates without such further approval.

9.03 Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed to constitute an original.

9.04 Governing Law. This Agreement shall be governed by, and interpreted in accordance with, the laws of the State of Delaware applicable to contracts made and to be performed entirely within such State.

9.05 Expenses. Each party hereto will bear all expenses incurred by it in connection with this Agreement and the transactions contemplated hereby (the "Deal Expenses"), provided that SDTB's Deal Expenses, which shall include the items set forth in Section 9.05 of SDTB's Disclosure Schedule, on an after Tax equivalent basis, shall not exceed $3,000,000, provided that if they do and subject to the next sentence, such will not be deemed a breach of this Agreement, and PPBI shall pay at Closing SDTB's Deal Expenses not paid prior to Closing, including expenses relating to legal, accounting and advisory (including the fee payable to Keefe, Bruyette, & ▇▇▇▇▇, Inc.). To the extent that SDTB's aggregate Deal Expenses (whether paid by SDTB prior to Closing or by PPBI at Closing), on an after Tax equivalent basis, exceed $3,000,000, any excess shall reduce the Per Share Cash Consideration by the quotient of (i) such excess divided by (ii) the total number of shares of issued and outstanding SDTB Common Stock. For purposes of this Agreement, "Deal Expenses" shall not include any costs or expenses incurred or accrued by SDTB in connection with or arising out of: (i) any litigation, arbitration, claim or other proceeding before any court or Governmental Authority that is brought against SDTB by a third-party and arising out of or in connection with this Agreement or the Transaction; (ii) any retention payments made or to be made to employees of SDTB; (iii) the acceleration of SDTB Stock Options; and/or (iv) obtaining the insurance policy as provided in Section 6.10(c), except for the costs and expenses for such policy in excess of the Maximum Insurance Amount, which excess amount shall be considered part of and included in "Deal Expenses."

Except for the Indemnified Parties' right to enforce PPBI's obligation under Section 6.10, which are expressly intended to be for the irrevocable benefit of, and shall be enforceable by, each Indemnified Party and his or her heirs and representatives, nothing in this Agreement, expressed or implied, is intended to confer upon any Person, other than the parties hereto or their respective successors, any rights, remedies, obligations or liabilities under or by reason of this Agreement.

9.08 Severability. Except to the extent that application of this Section 9.08 would have a Material Adverse Effect on SDTB or PPBI, 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. In all such

cases, the parties shall use their reasonable best efforts to substitute a valid, legal and enforceable provision which, insofar as practicable, implements the original purposes and intents of this Agreement.

9.09 Enforcement of the Agreement. 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. 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. In the event attorneys' fees or other costs are incurred to secure performance of any of the obligations herein provided for, or to establish damages for the breach thereof, or to obtain any other appropriate relief, whether by way of prosecution or defense, the prevailing party shall be entitled to recover reasonable attorneys' fees and costs incurred therein.

9.10 Interpretation. When a reference is made in this Agreement to Sections, Exhibits or Schedules, such reference shall be to a Section of, or Exhibit or Schedule to, this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and are not part of this Agreement. Whenever the words "include," "includes" or "including" are used in this Agreement, they shall be deemed to be followed by the words "without limitation." Whenever the words "as of the date hereof" are used in this Agreement, they shall be deemed to mean the day and year first above written.

9.11 Assignment. No party may assign either this Agreement or any of its rights, interests or obligations hereunder without the prior written approval of the other parties.

WHEREAS, Shareholder owns the shares of SDTB Common Stock identified on Exhibit I hereto (such shares, together with all shares of SDTB Common Stock subsequently acquired by Shareholder during the term of this Agreement, being referred to as the "Shares"); and

WHEREAS, in order to induce PPBI and Pacific Premier to enter into the Merger Agreement, Shareholder, solely in such Shareholder's capacity as a shareholder of SDTB and not in any other capacity, has agreed to enter into and perform this Agreement.

NOW, THEREFORE, for good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto agree as follows:

1. Agreement to Vote Shares. Shareholder agrees while this Agreement is in effect, that at any meeting of the shareholders of SDTB, or in connection with any written consent of the shareholders of SDTB, Shareholder shall:

(a) appear at each such meeting or otherwise cause the Shares to be counted as present thereat for purposes of calculating a quorum; and

(b) vote (or cause to be voted), in person or by proxy, or deliver a written consent (or cause a consent to be delivered) covering, all the Shares (whether acquired heretofore or hereafter) that are beneficially owned by Shareholder or as to which Shareholder has, directly or indirectly, the right to vote or direct the voting, (x) in favor of adoption and approval of the Merger, the Merger Agreement and the transactions contemplated thereby; (y) against any action or agreement that would reasonably be expected to result in a breach of any covenant, representation or warranty or any other obligation or agreement of SDTB contained in the Merger Agreement or of Shareholder contained in this Agreement; and (z) against any Acquisition Proposal or any other action, agreement or transaction that is intended, or would reasonably be expected, to materially impede, interfere or be inconsistent with, delay, postpone, discourage or materially and adversely affect consummation of the Merger or the performance by Shareholder of his, her or its obligations under this Agreement.

2. Transfer of Shares.

(a) Prohibition on Transfers of Shares; Other Actions. Shareholder hereby agrees that while this Agreement is in effect, Shareholder shall not, (i) sell, transfer, pledge, encumber, distribute by gift or donation, or otherwise dispose of any of the Shares (or any securities convertible into or exercisable or exchangeable for Shares) or any interest therein, whether by actual disposition, physical settlement or effective economic disposition through hedging transactions, derivative instruments or other means, (ii) enter into any agreement, arrangement or understanding with any

A-1

Person, or take any other action, that violates or conflicts with or could reasonably be expected to violate or conflict with Shareholder's representations, warranties, covenants and obligations under this Agreement, or (iii) take any other action that could reasonably be expected to impair or otherwise adversely affect, in any material respect, Shareholder's power, authority and ability to comply with and perform his, her or its covenants and obligations under this Agreement. Notwithstanding anything herein to the contrary, nothing herein shall prohibit Shareholder from taking any action contemplated by Section 3.09 of the Merger Agreement with respect to any SDTB Option, from exercising any SDTB Option, or from surrendering to SDTB of shares of SDTB Common Stock to pay the exercise price of any SDTB Option(s) or to satisfy SDTB's withholding obligations with respect to any taxes resulting from such exercise; provided however any shares of SDTB Common Stock received by Shareholders upon exercise of a SDTB Option shall at the time of issuance become subject to this Agreement.

(b) Transfer of Voting Rights. Shareholder hereby agrees that Shareholder shall not deposit any Shares in a voting trust, grant any proxy or enter into any voting agreement or similar agreement or arrangement with respect to any of the Shares.

(a) Capacity. Shareholder has all requisite capacity and authority to enter into and perform his, her or its obligations under this Agreement.

(b) Binding Agreement. This Agreement has been duly executed and delivered by Shareholder and constitutes the valid and legally binding obligation of Shareholder, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles.

(c) Non-Contravention. The execution and delivery of this Agreement by Shareholder does not, and the performance by Shareholder of his, her or its obligations hereunder and the consummation by Shareholder of the transactions contemplated hereby will not, violate or conflict with, or constitute a default under, any agreement, instrument, contract or other obligation or any order, arbitration award, judgment or decree to which Shareholder is a party or by which Shareholder is bound, or any statute, rule or regulation to which Shareholder is subject or, in the event that Shareholder is a corporation, partnership, trust or other entity, any charter, bylaw or other organizational document of Shareholder.

(d) Ownership. Shareholder's Shares are, and through the term of this Agreement will be, owned beneficially and of record solely by Shareholder, except as otherwise disclosed on Exhibit I hereto.

A-2

including the passage of time within 60 days, the satisfaction of any conditions, the occurrence of any event or any combination of the foregoing).

(e) Consents and Approvals. The execution and delivery of this Agreement by Shareholder does not, and the performance by Shareholder of his, her or its obligations under this Agreement and the consummation by him, her or it of the transactions contemplated hereby will not, require Shareholder to obtain any consent, approval, authorization or permit of, or to make any filing with or notification to, any Governmental Authority.

(f) Absence of Litigation. There is no suit, action, investigation or proceeding pending or, to the knowledge of Shareholder, threatened against or affecting Shareholder or any of his, her or its affiliates before or by any Governmental Authority that could reasonably be expected to materially impair the ability of Shareholder to perform his, her or its obligations hereunder or to consummate the transactions contemplated hereby on a timely basis.

4. No Solicitation. Shareholder hereby agrees that during the term of this Agreement he, she or it shall not, and shall not knowingly permit any investment banker, financial advisor, attorney, accountant or other representative retained by him, her or it to, directly or indirectly, (a) take any of the actions specified in clauses (i)-(vi) of Section 6.07(a) of the Merger Agreement, (b) agree to release, or release, any Person from any obligation under any existing standstill agreement or arrangement relating to SDTB, or (c) participate in, directly or indirectly, a "solicitation" of "proxies" (as such terms are used in the rules of the SEC) or powers of attorney or similar rights to vote, or seek to advise or influence any Person with respect to the voting of, any shares of SDTB Common Stock in connection with any vote or other action on any matter of a type described in Section 1(b), other than to recommend that shareholders of SDTB vote in favor of the adoption and approval of the Merger Agreement and the Merger and as otherwise expressly permitted by this Agreement. Shareholder agrees immediately to cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any Persons other than PPBI with respect to any possible Acquisition Proposal and will take all necessary steps to inform any investment banker, financial advisor, attorney, accountant or other representative retained by him, her or it of the obligations undertaken by Shareholder pursuant to this Section 4. Nothing contained in this Section 4 shall prevent a Shareholder who is an officer or a member of the SDTB Board from discharging his or her fiduciary duties solely in his or her capacity as such an officer or director.

5. Notice of Acquisitions; Proposals Regarding Prohibited Transactions. Shareholder hereby agrees to notify PPBI promptly (and in any event within two (2) Business Days) in writing of the number of any additional shares of SDTB Common Stock or other securities of SDTB of which Shareholder acquires beneficial or record ownership on or after the date hereof. Shareholder will comply with the provisions of Section 6.07(b) of the Merger Agreement as if he, she or it were SDTB.

6. Non-Solicitation.

(a) The Shareholder agrees that for a period of two (2) years following the Closing Date, the Shareholder will not, directly or indirectly, either as principal, manager, agent, consultant, advisor, independent contractor, officer, stockholder, partner, investor, lender or employee or in any other similar capacity:

(i) solicit (other than general solicitations through newspapers or other media of general circulation not targeted at such employees) any employees of SDTB prior to the Closing ("SDTB Employees"); or

(ii) (A) induce, persuade, encourage or influence or attempt to induce, persuade, encourage or influence any Person having a business relationship with PPBI, Pacific Premier or any of their Affiliates, to discontinue, reduce or restrict such relationship or (B) solicit or target the deposits, loans or other products and services from or to Persons who were

A-3

depositors, borrowers or customers of SDTB on the date of this Agreement, and/or as of the Closing Date, whether by personal contact, by telephone, by facsimile, by mail or other form of solicitation or communication, or in any other way except for general solicitations that are directed to the general public and not directed specifically to Persons who were depositors, borrowers or customers of SDTB on the date of this Agreement, or as of the Closing Date.

(b) The Shareholder acknowledges and agrees that the business conducted by SDTB is highly competitive and that the covenants made by the Shareholder in this Section 6 are made as a necessary inducement for PPBI and Pacific Premier to enter into the Merger Agreement and to consummate the transactions contemplated thereby. It is the desire and intent of the parties to this Agreement that the provisions of this Section 6 shall be enforced to the fullest extent permissible under the Laws and public policies of each jurisdiction in which enforcement is sought. It is expressly understood and agreed that although the Shareholder and PPBI each consider the restrictions contained in this Section 6 to be reasonable, if a final determination is made by a court of competent jurisdiction or an arbitrator that the time or territory or any other restriction contained in this Section 6 is unenforceable against any party, the provisions of this Section 6 shall be deemed amended to apply as to such maximum time and territory and to such maximum extent as such court may judicially determine or indicate to be enforceable.

(c) The Shareholder acknowledges and agrees that the provisions of this Agreement are necessary to protect PPBI's legitimate business interests and to protect the value of PPBI's acquisition of SDTB. The Shareholder warrants that these provisions will not unreasonably interfere with his or her ability to earn a living or to pursue his or her occupation and the Shareholder has the means to support himself or herself and his or her dependents and the provisions of this Section 6 will not impair such ability in any manner whatsoever.

(d) The Shareholder will not, at any time during the two-year period referred to in Subsection 6(a) of this Agreement, disparage PPBI, Pacific Premier or any of its Affiliates, or the business conducted by PPBI and Pacific Premier or any of their Affiliates, or any stockholder, member, director, manager, officer, employee or agent of PPBI, Pacific Premier or any of their Affiliates.

7. Specific Performance and Remedies. Shareholder acknowledges that it will be impossible to measure in money the damage to PPBI if Shareholder fails to comply with the obligations imposed by this Agreement and that, in the event of any such failure, PPBI will not have an adequate remedy at law. Accordingly, Shareholder agrees that injunctive relief or other equitable remedy, in addition to remedies at law or in damages, is the appropriate remedy for any such failure and will not oppose the granting of such relief on the basis that PPBI may have an adequate remedy at law. Shareholder agrees that Shareholder will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with PPBI's seeking or obtaining such equitable relief.

8. Term of Agreement; Termination.

(a) The term of this Agreement shall commence on the date hereof.

(b) This Agreement shall terminate upon the earlier to occur of (i) the date, if any, of termination of the Merger Agreement in accordance with its terms, or (ii) the Effective Time of the Merger. Upon such termination, no party shall have any further obligations or liabilities hereunder; provided, however, such termination shall not relieve any party from liability for any willful breach of this Agreement prior to such termination.

9. Stop Transfer Order. In furtherance of this Agreement, Shareholder hereby authorizes and instructs SDTB to enter a stop transfer order with respect to all of Shareholder's Shares for the period from the date hereof through the date this Agreement is terminated in accordance with Section 8. SDTB agrees that it shall comply with such stop transfer instructions.

For purposes hereof, the term Confidential and Proprietary Information shall not include any information or material (i) that is known to the general public other than due to a breach of this Agreement by the Executive or (ii) was disclosed to the Executive by a person who the Executive did not reasonably believe was bound to a confidentiality or similar agreement with the Bank.

Such a reduction in Executive's Base Salary shall be deemed a material reduction in Executive's compensation; or
(iii): Without the Executive's express written consent, the Bank requires the Executive to be based at a location more than 50 miles from San Diego, California (which requirement shall be deemed to be a material change in the geographic location at which the Executive must perform services for the Bank), except for required travel on business of the Bank to an extent substantially consistent with the Executive's present business travel obligations.

(k) IRS. IRS shall mean the Internal Revenue Service.

(l) Notice of Termination. Any termination of the Executive's employment by the Bank or the Executive shall be communicated by written "Notice of Termination" to the other party or parties hereto.

2. Term of Agreement.

(a) Effective only on the Closing Date and as provided in Section 22, the Bank hereby employs the Executive as Senior Vice President—Regional Manager of the Bank, and the Executive hereby accepts said employment and agrees to render such services to the Bank, on the terms and conditions set forth in this Agreement. The term of this Agreement shall be for a term of the earlier to occur of (i) three years, commencing on the Closing Date, unless such term is extended as provided in this Section 2 or (ii) the termination of Executive's employment with the Bank as provided in Section 5. Annually, not less than ninety (90) days prior to the anniversary of the date first above written, the Board of Directors of the Bank or a duly authorized committee thereof shall consider whether to extend the term of this Agreement. If either the Bank or the Executive gives written notice to the other party of such party's election not to extend the term, with such notice to be given not less than ninety (90) days prior to any such anniversary date, then this Agreement shall terminate at the conclusion of its remaining term. Otherwise, this Agreement shall be automatically extended for an additional one-year.

(b) While employed by the Bank, the Executive shall (i) perform such services for the Bank as may be consistent with the Executive's titles and such services which are from time to time assigned to the Executive by the Bank's Board of Directors and (ii) devote the Executive's entire business time, attention, skill and energy exclusively to the business of the Bank. While employed by the Bank, the Executive shall not engage or prepare to engage in any other business activity, whether or not such business activity is pursued for gain, profit or other economic or financial advantage; provided, however, that the Executive may engage in appropriate civic, charitable or religious activities and devote a reasonable amount of time to private investments or boards or other activities provided that such activities do not interfere or conflict with the Executive's responsibilities and are not or not likely to be contrary to the Bank's interests.

3. Compensation and Benefits.

(a) The Bank shall compensate and pay the Executive for services during the term of this Agreement at a base salary of $200,000 per year ("Base Salary"), which may be increased from time to time in such amounts as may be determined by the Board of Directors of the Bank. The Executive's Base Salary shall be paid in periodic installments (not less than monthly) in accordance with the general payroll practices of the Bank, as in effect from time-to-time.

(b) During the term of this Agreement, the Executive shall be entitled to participate in and receive the benefits of any pension or other retirement benefit plan, profit sharing, stock option, employee stock ownership, or other plans, benefits and privileges given to employees and executives of the Bank, to the extent commensurate with the Executive's then duties and responsibilities as fixed by the Board of Directors or the President of the Bank.

(c) During the term of this Agreement, the Executive shall be entitled to receive all benefits and conditions of employment generally available to other executives of the Bank, including, without limitation, sick leave, disability, accident, life, hospitalization, medical and dental insurance, paid holidays, and participation in any pension, profit sharing or other retirement plan pursuant to the terms of said plans.

(d) During the term of this Agreement, the Executive shall accrue paid vacation at the rate of eighteen days per year and paid sick leave at the rate of two hours per pay period, unless extended for years of service as governed by the Bank's Employee Handbook. Except as stated herein, other terms and conditions of the Executive's vacation and sick pay shall be governed by the Bank's Employee Handbook, as amended from time-to-time.

D-4

(e) The Executive shall be eligible to participate in the Bank's then existing discretionary incentive and/or bonus plans. The Executive must be an employee at the time of payment in order to be eligible to receive an incentive and/or bonus payment.

(f) During the term of this Agreement, the Bank shall provide the Executive with an automobile allowance in the amount of five hundred dollars ($500) per month for the costs of an automobile to be used by the Executive in the performance of his duties on behalf of the Bank as provided in this Agreement.

4. Expenses. Upon becoming employed by the Bank pursuant to Section 2(a), the Bank shall reimburse the Executive or otherwise provide for or pay for all reasonable expenses incurred by the Executive in furtherance of or in connection with the business of the Bank, including, but not by way of limitation, traveling expenses, subject to such reasonable documentation and other limitations as may be established by the Board of Directors of the Bank. If such expenses are paid in the first instance by the Executive, the Bank shall reimburse the Executive therefor.

5. Termination.

(a) The Bank shall have the right, at any time upon prior Notice of Termination, to terminate the Executive's employment hereunder for any reason, including, without limitation, termination for Cause or Disability, and the Executive shall have the right, upon prior Notice of Termination, to terminate Executive's employment hereunder for any reason. Notwithstanding the foregoing, from the period after the Closing Date and until November 1, 2013, the Bank shall give the Executive not less than one hundred twenty (120) days' prior Notice of Termination for any termination other than for Cause or death.

(b) In the event that (i) the Executive's employment is terminated by the Company for Cause or (ii) the Executive terminates his employment hereunder other than for Disability or Good Reason, the Executive shall have no right pursuant to this Agreement to compensation or other benefits for any period after the applicable Date of Termination other than for Base Salary accrued through the Date of Termination.

(c) In the event that the Executive's employment is terminated as a result of Disability or death after the Closing Date and during the term of this Agreement, the Executive or the Executive's estate (as the case may be) shall receive the Executive's existing Base Salary as in effect as of the Date of Termination or death, multiplied by one (1) year. Payment pursuant to this Subsection (c) shall be paid to the Executive or the Executive's estate (as the case may be) within sixty (60) days after the Date of Termination or death.

(d) In the event that the Executive's employment is terminated (i) by the Bank for other than Cause, Disability, or the Executive's death and such termination occurs within two (2) years following a Change of Control or (ii) by the Executive (a) due to a material breach of this Agreement by the Bank, or (b) for Good Reason, then the Bank shall, subject to Section 6 hereof, if applicable, provide the benefits described in subparagraphs (A) and (C) of this Section 5(d). Such a termination shall be deemed an involuntary termination if the breach or Good Reason basis for termination has not been cured within thirty (30) business days after a written notice of non-compliance has been given by the Executive to the Bank, such written notice has been given no more than ninety (90) days after the initial occurrence of the breach or the Good Reason basis for termination, and the termination occurs within two (2) years following the initial occurrence of the breach or the Good Reason basis for termination.

In the event that the Executive's employment is terminated by the Bank for other than Cause, Disability, or the Executive's death and such termination does not occur in conjunction with a Change in Control or two (2) years after a Change of Control, then the Bank shall,

D-5

subject to Section 6 hereof, if applicable, provide the benefits described in subparagraphs (B) and (C) of this Section 5(d). Such a termination shall be deemed an involuntary termination.

(A) Pay to the Executive a cash severance amount equal to the sum of the Base Salary plus Executive's incentive bonus for the previous year as in effect immediately prior to the Date of Termination, less taxes and other required withholding ("Severance Pay"). Such Severance Pay shall be paid in a lump sum on the first business day of the month following the Date of Termination. Notwithstanding the foregoing, no such Severance Pay will be paid to the Executive unless the Executive has undergone a Separation from Service.

(B) Pay to the Executive a cash severance amount equal to the Base Salary as in effect immediately prior to the Date of Termination, less taxes and other required withholdings ("Severance Pay"). Such Severance Pay shall be paid in a lump sum on the first business day of the month following the Date of Termination. Notwithstanding the foregoing, no such Severance Pay will be paid to Executive unless the Executive has undergone a Separation from Service.

(C) Maintain and provide for a period ending at the earlier of (i) the first anniversary of the Date of Termination or (ii) the date of the Executive's full-time employment by another employer, at no cost to the Executive, the Executive's continued participation in all group insurance, life insurance, health and accident, disability and other employee benefit plans, programs and arrangements in which the Executive was entitled to participate immediately prior to the Date of Termination (other than any stock option or other stock compensation plans or bonus plans of the Company or the Bank), provided that in the event that Executive's participation in any such plan, program or arrangement is barred, the Bank shall arrange to provide the Executive with benefits substantially similar to those the Executive was entitled to receive under such plans, programs and arrangements prior to the Date of Termination.

(e) In receiving any payments pursuant to Sections 5(c) and 5(d), the Executive shall not be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive hereunder, and such amounts shall not be reduced or terminated whether or not the Executive obtains other employment.

(f) Notwithstanding any provision of this Agreement to the contrary, if the Executive is a Specified Employee on the Date of Termination and, as a result thereof, Section 409A of the Code and the rules promulgated thereunder would so require, payments pursuant to Subsection (d) of this Section 5 may not commence earlier than six (6) months after the Date of Termination. Therefore, in the event this Subsection (f) is applicable, the payment required pursuant to Subsection (d) of this Section 5 shall be paid in a lump sum on the first day of the seventh month following the Date of Termination.

(g) In addition to the provisions of Sections 5(b) through 5(e), Executive or Executive's estate, as applicable, shall be entitled to Executive's Base Salary and vacation accrued through the Date of Termination or death, payable in accordance with California law, and reimbursement of all expenses pursuant to the provisions of Section 4.

6. Limitation of Benefits under Certain Circumstances. If the payments and benefits pursuant to Section 5 hereof, either alone or together with other payments and benefits which the Executive has the right to receive from the Bank, would constitute a "parachute payment" under Section 280G of the Code, the payments and benefits payable by the Bank pursuant to Section 5 hereof shall be reduced, in the manner determined by the Executive, by the amount, if any, which is the minimum necessary to result in no portion of the payments and benefits payable by the

D-6

Bank under Section 5 being non-deductible to the Bank pursuant to Section 280G of the Code and subject to the excise tax imposed under Section 4999 of the Code. The determination of any reduction in the payments and benefits to be made pursuant to Section 5 shall be based upon the opinion of independent counsel selected by the Bank's independent public accountants and paid by the Bank. Such counsel shall be reasonably acceptable to the Bank and the Executive; shall promptly prepare the foregoing opinion, but in no event later than thirty (30) days from the Date of Termination; and may use such actuaries as such counsel deems necessary or advisable for the purpose. Nothing contained herein shall result in a reduction of any payments or benefits to which the Executive may be entitled upon termination of employment under any circumstances other than as specified in this Section 6, or a reduction in the payments and benefits specified in Section 5 below zero.

7. Restrictions Respecting Confidential Information, Non-Competition and Non-Solicitation.

(a) The Executive acknowledges and agrees that by virtue of the Executive's position and involvement with the business and affairs of the Bank, the Executive will develop substantial expertise and knowledge with respect to all aspects of the Company's and the Bank's business, affairs and operations and will have access to all significant aspects of the business and operations of the Company and the Bank and to Confidential and Proprietary Information.

(b) The Executive hereby covenants and agrees that, during the term of employment as provided in Section 2(a) and thereafter, unless otherwise authorized by the Bank in writing, the Executive shall not, directly or indirectly, under any circumstance: (i) disclose to any other person or entity (other than in the regular course of business of the Bank) any Confidential and Proprietary Information, other than pursuant to applicable law, regulation or subpoena or with the prior written consent of the Bank; (ii) act or fail to act so as to impair the confidential or proprietary nature of any Confidential and Proprietary Information; (iii) use any Confidential and Proprietary Information other than for the sole and exclusive benefit of the Bank; or (iv) offer or agree to, or cause or assist in the inception or continuation of, any such disclosure, impairment or use of any Confidential and Proprietary Information. Following the term of employment, the Executive shall either return all documents, records and other items containing any Confidential and Proprietary Information to the Bank (regardless of the medium in which maintained or stored) or provide certification to the Bank as to their destruction.

(c) The Executive agrees that during the Executive's employment with the Bank and for a period of one (1) year after the Date of Termination (the "Covered Period"), the Executive will not, directly or indirectly, either as principal, manager, agent, consultant, advisor, independent contractor, officer, stockholder, partner, investor, lender or employee or in any other similar capacity:

(i) establish, acquire, engage in, operate, manage, own, advise, control or in any way participate, be employed by or otherwise engage in any Competitive Business (as defined below) or have any financial interest (including, without limitation, any interest in the voting or nonvoting equity or debt securities, partnership interests or similar securities, or warrants or options thereon) in any person or entity that engages in any Competitive Business, provided that the Executive may acquire less than 5% of the equity of any Competitive Business so long as such acquisition is and remains solely for investment purposes; or

(ii) (A) solicit (other than general solicitations through newspapers or other media of general circulation not targeted at such employees) any employees of the Bank and its Affiliates who are then still employees ("Covered Employees"); or

D-7

(iii) (A) induce, persuade, encourage or influence or attempt to induce, persuade, encourage or influence any person or entity having a business relationship with the Bank or any of its Affiliates, to discontinue, reduce or restrict such relationship or (B) solicit or target the deposits, loans or other banking products and services from or to persons or entities who were depositors, borrowers or customers of the Bank or its Affiliates on the Date of Termination, whether by personal contact, by telephone, by facsimile, by mail or other form of solicitation or communication, or in any other way, except for general solicitations that are directed to the general public and not directed specifically to persons or entities who were depositors, borrowers or customers of the Bank or its Affiliates as of the Date of Termination.

For purposes of this Agreement, the term "Competitive Business" shall mean the business or operations of a bank, credit union, industrial bank, any other financial institution, bank holding company or savings and loan holding company operating within San Diego County, California.

(d) The Executive acknowledges that as a result of the Executive's employment with the Bank, the Executive has held and will continue to hold a position of the highest trust in which the Executive comes to know the Bank's employees, its customers and its Confidential and Proprietary Information. The Executive agrees that the provisions of Section 7(c) are necessary to protect the Bank's legitimate business interests. The Executive warrants that these provisions will not unreasonably interfere with the Executive's ability to earn a living or to pursue the Executive's occupation after the Executive's employment ends for any reason.

(e) It is the desire and intent of the parties to this Agreement that the provisions of this Section 7 shall be enforced to the fullest extent permissible under the laws and public policies of each jurisdiction in which enforcement is sought. It is expressly understood and agreed that although the Executive and the Bank each consider the restrictions contained in this Section 7 to be reasonable, if a final determination is made by a court of competent jurisdiction or an arbitrator that the time or territory or any other restriction contained in this Section 7 is unenforceable against any party, the provisions of this Section 7 shall be deemed amended to apply as to such maximum time and territory and to such maximum extent as such court may judicially determine or indicate to be enforceable. The parties agree that nothing in this Agreement shall be construed to limit or negate the common law of torts, confidentiality, trade secrets, fiduciary duty and obligations where such laws provide the Bank with any broader, further or other remedy or protection than those provided herein.

(f) Because the breach of any of the provisions of this Section 7 will result in immediate and irreparable injury to the Bank for which the Bank will not have an adequate remedy at law, the Bank shall be entitled, in addition to all other rights and remedies, to seek a degree of specific performance of the restrictive covenants contained in this Section 7 and to a temporary and permanent injunction enjoining such breach, without posting bond or furnishing similar security.

8. Cooperation in Legal Proceedings. After the Date of Termination, the Executive agrees to reasonably cooperate with the Bank and any of its Affiliates in the defense or prosecution of any claims or actions that may be brought against or on behalf of the Bank or its Affiliates, which relate to events or occurrences that transpired while the Executive was employed by the Bank. The Executive's reasonable cooperation in connection with such claims or actions shall include, but not be limited to, being available to meet with counsel to prepare for discovery or trial and to act as a witness on behalf of the Bank or any of its Affiliates. The Executive also agrees to reasonably cooperate with the Bank and any of its Affiliates in connection with any investigation or review of any federal, state, or local regulatory authority as any such investigation or review relates to any

D-8

acts or omissions that transpired while the Executive was employed by the Bank. The Executive understands that in any legal action, investigation, or review covered by this Section 8 that the Bank expects the Executive to provide only accurate and truthful information or testimony. The Bank will pay expenses necessarily and reasonably incurred by the Executive in complying with this Section 8.

9. Work Product. The Executive acknowledges that all inventions, innovations, improvements, developments, methods, designs, analyses, drawings, reports and all similar or related information (whether or not patentable) which relate to the Bank or its Affiliates, research and development or existing or future products or services and which are conceived, developed or made by the Executive while employed by the Bank and its Affiliates ("Work Product") belong to the Bank or such Affiliates (as applicable). The Executive shall promptly disclose such Work Product to the Board of Directors of the Bank and perform all actions reasonably requested by the Board of Directors of the Bank (whether during or after the Executive's employment with the Bank) to establish and confirm such ownership (including, without limitation, executing assignments, consents, powers of attorney and other instruments).

10. Return of Property. On and after the Date of Termination for any reason, or at any time during the Executive's employment, on the request or direction of the Company or the Bank, the Executive will immediately deliver to the Bank any or all equipment, property, material, Confidential and Proprietary Information, Work Product or copies thereof which are owned by the Bank, the Company or their respective Affiliates and are in the Executive's possession or control. This includes documents or other information prepared by the Executive, on the Executive's behalf or provided to the Executive in connection with the Executive's duties while employed by the Bank, regardless of the form in which such document or information are maintained or stored, including computer, typed, written, electronic, audio, video, micro-fiche, imaged, drawn or any other means of recording or storing documents or other information. The Executive hereby warrants that the Executive will not retain in any form such documents, Confidential and Proprietary Information, Work Product or other information or copies thereof. The Executive may retain a copy of this Agreement and any other document or information describing any rights the Executive may have after the termination of the Executive's employment.

11. Dispute Resolution. The Executive and the Bank agree that arbitration in accordance with the Federal Arbitration Act and the Dispute Resolution Procedures set forth in Attachment A to this Agreement shall be the exclusive means for final resolution of any dispute between the parties arising out of or relating to the Executive's employment or this Agreement, except (1) for workers' compensation and unemployment claims; (2) when injunctive relief is necessary to preserve the status quo or to prevent irreparable injury; and (3) any claims arising from or relating to Section 7 of this Agreement. Injunctive relief may be sought only from any court of competent jurisdiction located in Orange County, California and the Executive consents to venue and personal jurisdiction in any such court. The parties hereto agree that the arbitration provided for hereunder shall be conducted by the Judicial Arbitration and Mediation Services, Inc. ("JAMS"), presently located in Orange County, California. In the event JAMS is unable or unwilling to conduct the arbitration provided for under the terms of this Section 11, or has discontinued its business, the parties agree that the American Arbitration Association, presently located in Orange County, California, shall conduct the binding arbitration referred to in this Section 11. If any part of this Agreement is held by an arbitrator or court of competent jurisdiction to be void or unenforceable, the remaining provisions shall continue with full force and effect. If this Agreement shall be determined by any court or an arbitrator to be unenforceable because of its duration, or the scope of activities, information or geographic area covered, the parties agree that this Agreement shall be interpreted to extend to the maximum period of time or range of activities, information or geographic area that would be enforceable.

D-9

12. Withholding. All payments required to be made by the Bank hereunder to the Executive shall be subject to the withholding of such amounts, if any, relating to tax and other payroll deductions as the Bank may reasonably determine should be withheld pursuant to any applicable law or regulation.

13. Assignability. The Bank may assign this Agreement and its rights and obligations hereunder in whole, but not in part, from and after the Closing Date to any corporation or other entity with or into which the Bank may hereafter merge or consolidate or to which the Bank may transfer all or substantially all of its assets, if in any such case said corporation or other entity shall by operation of law or expressly in writing assume all obligations of the Bank hereunder as fully as if it had been originally made a party hereto, but may not otherwise assign this Agreement or its rights and obligations hereunder. The benefits provided under this Agreement shall inure to the benefit of and be enforceable by the Executive's personal or legal representatives, executors, administrators, successors, heirs, devisees and legatees. If the Executive shall die while any amounts would be payable to Executive hereunder had the Executive continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to such person or persons appointed in writing by the Executive to receive such amounts, or, if no person is so appointed, to the Executive's estate. Except as otherwise provided in this Section 13, the Executive may not assign or transfer this Agreement or any rights or obligations hereunder.

14. Notice. For the purposes of this Agreement, notices and all other communications provided for in this Agreement shall be in writing and shall be deemed to have been duly given when delivered or mailed by certified or registered mail, return receipt requested, postage prepaid, addressed to the respective addresses set forth on the signature page hereto. Any notice, request, demand or other communication delivered or sent in the manner aforesaid shall be deemed given or made (as the case may be) upon the earliest of (a) the date it is actually received, (b) the business day after the day on which it is delivered by hand, (c) the business day after the day on which it is properly delivered to Federal Express (or a comparable overnight delivery service), or (d) the third business day after the day on which it is deposited in the United States mail. The Bank or the Executive may change their respective addresses by notifying the other party of the new addresses in any manner permitted by this Section 14.

15. Amendment; Waiver. No provisions of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing and signed by the Executive and such officer or officers as may be specifically designated by the Board of Directors of the Bank to sign on its behalf. No waiver by any party hereto at any time of any breach by any other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time.

16. Governing Law. The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the United States where applicable and otherwise by the substantive laws of the State of California, without regard to any conflicts of laws provisions thereof.

17. Nature of Obligations. Nothing contained herein shall create or require the Bank to create a trust of any kind to fund any benefits which may be payable hereunder, and to the extent that the Executive acquires a right to receive benefits from the Bank hereunder, such right shall be no greater than the right of any unsecured general creditor of the Bank.

18. Headings. The section headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

A.: The party claiming to be aggrieved ("Claimant") shall furnish to the other a written statement of the grievance, all Persons whose testimony would support the grievance, and the relief requested or proposed. The written statements must be delivered to the other party within the time limits for bringing an administrative or court action based on that claim.
B.: If the other party does not agree to furnish the relief requested or proposed, or otherwise does not satisfy the demand of the Claimant within 30 days and the Claimant wishes to pursue the issue, the Claimant shall give notice to the other of the Claimant's demand that the dispute be submitted to non-binding mediation before a mediator jointly selected by the parties or the parties cannot agree on a mediator selected from a list provided by JAMS. Such mediation should occur within 90 days of the demand for mediation.

The arbitration will be conducted consistent with JAMS' rules governing employment disputes ("Rules") that are in effect at the time of the arbitration. If there is any conflict between those Rules and the Procedures, the Procedures will govern. The arbitrator shall have authority to decide whether the conduct complained of under Section A above violates the legal rights of the parties. In any such arbitration proceeding, any hearing must be supported by written findings of fact and conclusions of law. The arbitrator's findings of fact must be supported by substantial evidence on the record as a whole, and the conclusions of law and any remedy must be provided for by and consistent with the laws of California and federal law. The arbitrator shall have no authority to add to, modify, change or disregard any lawful term of the Agreement. The Bank will pay the arbitrator's fee. Any award that may result from such arbitration may be confirmed into a judgment from a court and enforced in accordance with applicable law.

ANNEX E

CONFIDENTIALITY, NON-COMPETITION AND NON-SOLICITATION AGREEMENT

THIS CONFIDENTIALITY, NON-COMPETITION AND NON-SOLICITATION AGREEMENT ("Agreement") dated March 5, 2013 by and between ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇ ("Shareholder") and Pacific Premier Bank (the "Bank").

W I T N E S S E T H

WHEREAS, the Shareholder is currently employed by San Diego Trust Bank ("SDTB") as its President and Chief Executive Officer and is a shareholder of SDTB;

WHEREAS, the Bank, Pacific Premier Bancorp, Inc., a Delaware corporation and bank holding company for the Bank (the "Company"), and SDTB entered into an Agreement and Plan of Reorganization, dated March 5, 2013 (the "Merger Agreement"), which provides for the Company's acquisition of SDTB, including the goodwill associated with SDTB's business;

WHEREAS, as a result of his employment with, and participation in the affairs of, SDTB as its principal executive officer, Shareholder has acquired significant knowledge and proprietary and confidential trade information regarding SDTB and its business affairs and strategies;

WHEREAS, as a result of his involvement in transactions contemplated by the Merger Agreement on behalf of SDTB, Shareholder has acquired significant knowledge and proprietary and confidential trade information regarding the Company and the Bank and their business affairs and strategies;

WHEREAS, as a shareholder of SDTB, Shareholder will materially benefit from the acquisition of SDTB by the Company pursuant to the terms of the Merger Agreement, and desires that the transactions contemplated by the Merger Agreement be consummated; and

WHEREAS, Shareholder's execution of and continued compliance with this Agreement, and the protection and maintenance of SDTB's goodwill that is served thereby, are a material inducement for the Company and the Bank to enter into the Merger Agreement and are a condition precedent for the Company and the Bank to consummate the transactions contemplated by the Merger Agreement.

NOW, THEREFORE, in consideration of the mutual covenants herein set forth, Shareholder and the Bank do agree to the following terms:

1. Definitions. The following words and terms shall have the meanings set forth below for the purposes of this Agreement:

(a) Affiliate. Affiliate of any person or entity means any stockholder, person, or entity controlling, controlled by, or under common control with such person or entity, or any director, officer or key executive of such entity or any of their respective relatives. For purposes of this definition, "control," when used with respect to any person or entity, means the power to direct the management and policies of such person or entity, directly or indirectly, whether through ownership of voting securities, by contracting or otherwise; and the terms "controlling" and "controlled" have meanings that correspond to the foregoing.

(b) Confidential and Proprietary Information. "Confidential and Proprietary Information" shall mean any and all (i) confidential or proprietary information or material not in the public domain about or relating to the business, operations, assets or financial condition of SDTB, the Company, the Bank or any Affiliate of any of the foregoing (collectively, a "Covered Party") or any Covered Party's trade secrets; and (ii) information, documentation or material not in the public domain by virtue of any action by or on the part of Shareholder, the knowledge of which gives or may give a Covered Party an advantage over any person not possessing such information. For purposes hereof, the term "Confidential and Proprietary

E-1

Information" shall not include any information or material (i) that is known to the general public other than as a result of Shareholder's breach of this Agreement or (ii) that was disclosed to Shareholder by a person who Shareholder did not reasonably believe was bound to a confidentiality or similar agreement with a Covered Party.

(c) Closing Date. "Closing Date" shall mean the "Closing Date" as defined in the Merger Agreement.

2. Restrictions Respecting Confidential Information, Non-Competition and Non-Solicitation.

(a) Shareholder covenants and agrees that, unless otherwise authorized by the Bank in writing, Shareholder shall not, directly or indirectly, under any circumstance: (i) disclose to any other person or entity any Confidential and Proprietary Information, other than pursuant to applicable law, regulation or subpoena or with the prior written consent of the Bank; (ii) act or fail to act so as to impair the confidential or proprietary nature of any Confidential and Proprietary Information; (iii) use any Confidential and Proprietary Information other than for the sole and exclusive benefit of the Bank; or (iv) offer or agree to, or cause or assist in the inception or continuation of, any such disclosure, impairment or use of any Confidential and Proprietary Information. Promptly following the Closing Date, Shareholder shall either deliver to the Bank all documents, records and other items containing any Confidential and Proprietary Information (regardless of the medium in which maintained or stored) in his possession or provide certification to the Bank as to their destruction.

(b) In consideration of the amount payable to Shareholder pursuant to Section 3, Shareholder agrees that for a period of three (3) years beginning with the Closing Date (the "Covered Period"), Shareholder will not, directly or indirectly, either as principal, manager, agent, consultant, advisor, independent contractor, officer, stockholder, partner, investor, lender or employee or in any other similar capacity:

(i) establish, acquire, engage in, operate, manage, own, advise, control or in any way participate, be employed by or otherwise engage in any Competitive Business or have any financial interest (including, without limitation, any interest in the voting or nonvoting equity or debt securities, partnership interests or similar securities, or warrants or options thereon) in any person or entity that engages in any Competitive Business, provided that Shareholder may acquire less than 5% of the equity of any Competitive Business so long as such acquisition is and remains solely for investment purposes; or

(ii) solicit (other than general solicitations through newspapers or other media of general circulation not targeted at such employees) any employees of the Bank and its Affiliates who are then still employees ("Covered Employees"); or

(iii) (A) induce, persuade, encourage or influence or attempt to induce, persuade, encourage or influence any person or entity having a business relationship with the Bank or any of its Affiliates, to discontinue, reduce or restrict such relationship or (B) solicit or target the deposits, loans or other banking products and services from or to persons or entities who were depositors, borrowers or customers of the Bank or its Affiliates as of the Closing Date, whether by personal contact, by telephone, by facsimile, by mail or other form of solicitation or communication, or in any other way, except for general solicitations that are directed to the general public and not directed specifically to persons or entities who were depositors, borrowers or customers of the Bank or its Affiliates as of the Closing Date.

For purposes of this Agreement, the term "Competitive Business" shall mean the business or operations of a bank, credit union or industrial bank operating within San Diego County, California.

E-2

(c) Shareholder agrees that the provisions of Section 2(b) are necessary to protect the Bank's legitimate business interests. Shareholder warrants that these provisions will not unreasonably interfere with Shareholder's ability to earn a living or to pursue Shareholder's occupation. Shareholder agrees to promptly notify the Bank of the name and address of any person or entity to which Shareholder provides services during the Covered Period and authorizes the Bank, after consultation with Shareholder as to the form and content of any such notice, to notify that entity of Shareholder's obligations under this Agreement.

(d) It is the desire and intent of the parties to this Agreement that the provisions of this Section 2 shall be enforced to the fullest extent permissible under the laws and public policies of each jurisdiction in which enforcement is sought. It is expressly understood and agreed that although Shareholder and the Bank each consider the restrictions contained in this Section 2 to be reasonable, if a final determination is made by a court of competent jurisdiction or an arbitrator that the time or territory or any other restriction contained in this Section 2 is unenforceable against any party, the provisions of this Section 2 shall be deemed amended to apply as to such maximum time and territory and to such maximum extent as such court may judicially determine or indicate to be enforceable.

(e) The parties to this Agreement agree that nothing in this Agreement shall be construed to limit or negate the common law of torts, confidentiality, trade secrets, fiduciary duty and obligations where such laws provide the Bank with any broader, further or other remedy or protection than those provided herein.

(f) Because the breach of any of the provisions of this Section 2 will result in immediate and irreparable injury to the Bank for which the Bank will not have an adequate remedy at law, the Bank shall be entitled, in addition to all other rights and remedies, to seek a decree of specific performance of the restrictive covenants contained in this Section 2 and to a temporary and permanent injunction enjoining such breach, without posting bond or furnishing similar security.

3. Consideration. In consideration of the restrictive covenants provided for in Section 2 above, the Bank shall pay to Shareholder a fee, which fee shall be paid in three (3) equal annual installments of $375,000, with the first installment payable on the Closing Date and the remaining two (2) installments payable on the first and second anniversaries of the Closing Date.

4. Shareholder Representations. Shareholder represents, stipulates and acknowledges that (a) Shareholder's experience and capabilities are such that the provisions herein contained will not prevent Shareholder from earning a livelihood, (b) the execution of this Agreement was a material inducement to the Company and the Bank to enter into the Merger Agreement for which Shareholder will receive a substantial financial benefit, (c) it would impair the goodwill acquired by the Company and reduce the value of SDTB obtained by the Company through the transactions contemplated by the Merger Agreement, if Shareholder were to use his ability and knowledge in competition with the Company and/or the Bank, or to otherwise breach the obligations contained herein and (d) the foregoing restrictions on competition are fair and reasonable in the type of prohibited activity and both geographic and temporal scope.

5. Cooperation in Legal Proceedings. Shareholder agrees to reasonably cooperate with the Bank and any of its Affiliates in the defense or prosecution of any claims or actions that may be brought against or on behalf of the Bank or its Affiliates, which relate to events or occurrences that transpired while Shareholder was providing services to SDTB. Shareholder's reasonable cooperation in connection with such claims or actions shall include, but not be limited to, being available to meet with counsel to prepare for discovery or trial and to act as a witness on behalf of the Bank or any of its Affiliates. Shareholder also agrees to reasonably cooperate with the Bank and any of its Affiliates in connection with any investigation or review of any federal, state, or

E-3

local regulatory authority as any such investigation or review relates to any acts or omissions that transpired while Shareholder was providing services to SDTB. Shareholder understands that in any legal action, investigation, or review covered by this Section 5 that the Bank expects Shareholder to provide only accurate and truthful information or testimony. The Bank will pay expenses necessarily and reasonably incurred by Shareholder in complying with this Section, provided that no right to the expenses (whether as a reimbursement or in-kind benefit) shall be subject to liquidation or exchange for another benefit. Reimbursement shall be made promptly after such expenses are incurred (provided adequate proof has been provided in compliance with applicable Bank policies).

6. Assignability. The Bank may assign this Agreement and its rights and obligations hereunder in whole, but not in part, to any corporation, bank, or other entity with or into which the Bank may hereafter merge or consolidate or to which the Bank may transfer all or substantially all of its assets, if in any such case said corporation, bank or other entity shall by operation of law or expressly in writing assume all obligations of the Bank hereunder as fully as if it had been originally made a party hereto, but may not otherwise assign this Agreement or its rights and obligations hereunder. If Shareholder should die while any amounts would be payable to Shareholder hereunder had Shareholder continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to such person or persons appointed in writing by Shareholder to receive such amounts, or, if no person is so appointed, to Shareholder's estate. Except as otherwise provided in this Section 6, Shareholder may not assign or transfer this Agreement or any rights or obligations hereunder.

7. Notice. For the purposes of this Agreement, notices and all other communications provided for in this Agreement shall be in writing and shall be deemed to have been duly given when delivered or mailed by certified or registered mail, return receipt requested, postage prepaid, addressed to the respective addresses set forth on the signature page hereto. Any notice, request, demand or other communication delivered or sent in the manner aforesaid shall be deemed given or made (as the case may be) upon the earliest of (a) the date it is actually received, (b) the business day after the day on which it is delivered by hand, (c) the business day after the day on which it is properly delivered to Federal Express (or a comparable overnight delivery service), or (d) the third business day after the day on which it is deposited in the United States mail. The Bank or Shareholder may change its address by notifying the other party of the new address in any manner permitted by this Section 7.

8. Amendment; Waiver. No provisions of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing and signed by Shareholder and such officer or officers as may be specifically designated by the Board of Directors of the Bank to sign on its behalf. No waiver by any party hereto at any time of any breach by any other party hereto of, or compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time.

9. Governing Law and Forum. The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the United States where applicable and otherwise by the substantive laws of the State of California.

10. Nature of Obligations. Nothing contained herein shall create or require the Bank to create a trust of any kind to fund any benefits which may be payable hereunder, and to the extent that Shareholder acquires a right to receive benefits from the Bank hereunder, such right shall be no greater than the right of any unsecured general creditor of the Bank.

11. Headings. The section headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

E-4

12. Validity. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provisions of this Agreement, which shall remain in full force and effect.

13. Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument.

14. Effectiveness. This Agreement shall become effective as of the Closing Date of the transactions contemplated under the Merger Agreement, but shall have no force or effect unless and until the Effective Time (as defined in the Merger Agreement) occurs. This Agreement shall terminate and be of no force and effect if the Merger Agreement is terminated.

15. Entire Agreement. This Agreement embodies the entire agreement between the Bank and Shareholder with respect to the matters agreed to herein. All prior agreements between the Bank and Shareholder with respect to the matters agreed to herein are hereby superseded and shall have no force or effect.
