THIS AGREEMENT AND PLAN OF MERGER, dated as of December 9, 2010 (this “Agreement”), is entered into between NARA BANCORP, INC., a Delaware corporation (“Nara”), and CENTER FINANCIAL CORPORATION, a California corporation (“Center Financial”). Nara and Center Financial are sometimes referred to herein collectively as the “Parties” and individually as a “Party.”

WHEREAS, the boards of directors of Nara and Center Financial have approved, and declared it to be advisable and in the best interests of their respective stockholders to consummate, the business combination transaction provided for herein in which Center Financial would merge with and into Nara (the “Merger”);

WHEREAS, the boards of directors of Nara and Center Financial have each determined that the Merger and the other transactions contemplated hereby are consistent with, and in furtherance of, their respective business strategies and goals;

WHEREAS, Nara and Center Financial desire to make certain representations, warranties, covenants and agreements in connection with the Merger and also to prescribe various conditions to the Merger;

WHEREAS, for federal income tax purposes, it is intended that the Merger shall qualify as a reorganization under the provisions of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and the Parties intend, by executing this Agreement, to adopt a plan of reorganization within the meaning of Treasury Regulation Section 1.368-2(g); and

WHEREAS, the boards of directors of Nara’s wholly owned subsidiary, Nara Bank, a California state chartered banking corporation (“Nara Bank”), and Center Financial’s wholly owned subsidiary, Center Bank, a California state chartered banking corporation (“Center Bank”), have approved, and declared it to be advisable and in the best interests of their respective stockholders, Nara and Center Financial, to consummate, concurrently with or as soon as reasonably practicable after the Merger, a business combination transaction in which Center Bank would merge with and into Nara Bank (the “Bank Merger”).

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth herein, subject to the conditions set forth herein, and intending to be legally bound hereby, the Parties agree as follows:

ARTICLE I

THE MERGER

1.1 Effective Time of the Merger. Upon the terms and subject to the conditions set forth in this Agreement, Nara and Center Financial shall cause the Merger to be consummated by filing a certificate of merger (the “Certificate of Merger”) with the Secretary of State of the State of Delaware, in such form as required by, and executed in accordance with, the relevant provisions of the Delaware General Corporation Law (the “DGCL”), and shall concurrently cause the Certificate of Merger, or any other certificate, agreement or other document specified in the relevant provisions of the California General

Corporation Law (the “CGCL”) to cause the Merger to be effective in California, to be filed with the Secretary of State of the State of California, in such form as required by, and executed in accordance with, the relevant provisions of the CGCL. The Merger shall become effective upon (a) such filing of the Certificate of Merger with the Secretary of State of the State of Delaware or (b) such later date and time as may be specified in the Certificate of Merger (the “Effective Time”).

1.2 Closing. The closing of the Merger (the “Closing”) will take place at 10:00 a.m. on the date (the “Closing Date”) that is the third business day after the satisfaction or waiver of the conditions set forth in Article VI (excluding those conditions that, by their nature, are to be satisfied as of the Closing, but subject to the satisfaction or waiver of those conditions as of the Closing), unless another time or date is agreed to in writing by the Parties. The Closing shall be held at the offices of ▇▇▇▇▇ ▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, unless another place is agreed to in writing by the Parties.

1.3 Effects of the Merger. Nara shall be the Surviving Corporation in the Merger. At the Effective Time, Center Financial shall be merged with and into Nara and the separate existence of Center Financial shall cease. The Merger will have the effects set forth in the DGCL and the CGCL.

1.4 Certificate of Incorporation and By-Laws. The Certificate of Incorporation of Nara as in effect immediately prior to the Effective Time shall be the Certificate of Incorporation of the Surviving Corporation, except that such Certificate of Incorporation shall be amended to provide that, effective as of the Effective Time, the name of the Surviving Corporation shall be changed to a name mutually acceptable to Center Financial and Nara. The By-laws of Nara as in effect immediately prior to the Effective Time, as amended substantially in the form set forth in Exhibit 1.4, shall be the By-laws of the Surviving Corporation.

1.5 Bank Merger. As soon as reasonably practicable after the date hereof, Nara and Center Financial shall cause Nara Bank and Center Bank to enter into a bank merger agreement in substantially the form attached to this Agreement as Exhibit 1.5 (the “Bank Merger Agreement”), providing for the Bank Merger in accordance with Applicable Legal Requirements and the terms of the Bank Merger Agreement concurrently with or as soon as reasonably practicable after consummation of the Merger.

ARTICLE II

EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE

CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

2.1 Effect on Capital Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of Nara, Center Financial or the holder of any of the following securities:

(a) Cancellation of Stock Owned by the Parties. Any shares of Center Financial Common Stock that are issued and outstanding immediately prior to the Effective

Time and are owned by Center Financial or Nara (other than, for the avoidance of doubt, any DPC shares or shares for which Center Financial is the record holder for the benefit of another Person) shall be cancelled and retired and no stock of Nara or other consideration shall be delivered in exchange therefor. Any shares of Nara Common Stock that are issued and outstanding immediately prior to the Effective Time and are owned by Center Financial (other than, for the avoidance of doubt, any DPC shares or shares for which Center Financial is the record holder for the benefit of another Person) shall be cancelled and retired.

(b) Conversion of Center Financial Common Stock. Subject to Section 2.2(e), each share of Center Financial Common Stock issued and outstanding immediately prior to the Effective Time (other than shares to be cancelled in accordance with Section 2.1(a) and dissenting shares as provided in Section 2.1(f)) shall be converted into 0.7804 (the “Exchange Ratio”) fully paid and nonassessable shares of Nara Common Stock. None of such shares of Center Financial Common Stock shall remain outstanding and all of such shares shall automatically be cancelled and retired and shall cease to exist, and each stock certificate previously representing any such shares shall thereafter represent solely the shares of Nara Common Stock into which such Center Financial Common Stock has been converted and the right pursuant to Section 2.2(e) to receive payment of cash in lieu of the issuance of fractional shares, without interest, if applicable. The Parties acknowledge and agree that the Exchange Ratio has been determined based upon (i) the number of shares of Center Financial Common Stock and Center Financial Restricted Shares and Nara Common Stock and Nara’s performance units issued under the Nara Stock Plan (the “Nara Performance Units”) represented and warranted herein by the respective Parties to be issued and outstanding, in each case as of November 30, 2010, as set forth in Section 3.1(b)(i) and Sections 3.2(b)(i) and 3.2(b)(iii), respectively, and (ii) on a diluted basis using the treasury stock method, each issued and outstanding Center Financial Stock Option and Nara Stock Option with an exercise price that was below the closing price of a share of Nara Common Stock and Center Financial Common Stock, respectively, as reported on the NASDAQ website at the close of NASDAQ’s regular session of trading on December 8, 2010, and represented and warranted herein by the respective Parties to be issued and outstanding as of November 30, 2010, as set forth in Sections 3.1(b)(i) and 3.2(b)(i). Other than any increases in outstanding shares of Center Financial Common Stock or Nara Common Stock resulting from the exercise of Center Financial Stock Options and Nara Stock Options issued and outstanding as of the date hereof, if the number of shares of Center Financial Common Stock or Nara Common Stock or the number of Center Financial Restricted Shares or Nara Performance Units that are issued and outstanding shall have increased or decreased as of the Closing, whether as permitted by or in breach of this Agreement, the Parties agree that, without limiting any other right or remedy to which the Parties are entitled at law or in equity, a corresponding adjustment shall be made to the Exchange Ratio such that holders of Center Financial Common Stock and holders of Nara Common Stock shall receive 45% and 55%, respectively, of the outstanding shares of common stock of the Surviving Corporation after the Merger is consummated. The Exchange Ratio, as recalculated, if applicable, shall, for all purposes hereunder, constitute the “Exchange Ratio.”

(c) Conversion of Center Financial Series A Preferred Stock. Each share of Center Financial Series A Preferred Stock issued and outstanding immediately prior to the Effective Time shall be converted into one fully paid and nonassessable share of Nara

Preferred Stock designated as Fixed Rate Cumulative Perpetual Preferred Stock, Series B (the “Nara Series B Preferred Stock”), which series of Nara Preferred Stock shall be authorized by action of the board of directors of Nara (the “Nara Board”) pursuant to the Certificate of Incorporation of Nara as in effect immediately prior to the Effective Time. The Nara Board shall take all necessary action to create the Nara Series B Preferred Stock prior to the Effective Time. The shares of Nara Series B Preferred Stock shall have, in respect of Nara, the same rights, preferences, privileges and voting powers, and limitations and restrictions thereof, as the shares of Center Financial Series A Preferred Stock had in respect of Center Financial immediately prior to the Effective Time. None of such shares of Center Financial Series A Preferred Stock shall remain outstanding and all of such shares shall automatically be cancelled and retired and shall cease to exist, and each stock certificate previously representing any such shares shall thereafter represent solely the shares of Nara Series B Preferred Stock into which such Center Financial Series A Preferred Stock has been converted, without interest.

(d) Stock Options and Other Equity-Based Awards. Unless otherwise agreed by Center Financial after the date hereof:

(i) Assumption of Center Financial Options. Center Financial and Nara shall take all actions necessary (including delivery of any required notices by Center Financial) to provide that, effective as of the Effective Time, without any action on the part of the holders thereof, each outstanding Center Financial Stock Option shall cease to represent the right to acquire shares of Center Financial Common Stock and shall instead be converted automatically into an option to acquire shares of Nara Common Stock as provided below (an “Assumed Option”), and such Assumed Options will be assumed by Nara on substantially the same terms and conditions as were applicable under the corresponding Center Financial Stock Options immediately prior to the Effective Time; provided, however, that after the Effective Time:

(1) each Assumed Option will be exercisable for a number of shares of Nara Common Stock equal to the product of (x) the number of shares of Center Financial Common Stock that would be issuable upon exercise of such Center Financial Stock Option outstanding immediately prior to the Effective Time multiplied by (y) the Exchange Ratio, rounded down to the nearest whole share; and

(2) the per share exercise price for the Nara Common Stock issuable upon exercise of such Assumed Option will be equal to the quotient determined by dividing (x) the per share exercise price for such Center Financial Stock Option outstanding immediately prior to the Effective Time by (y) the Exchange Ratio, rounded up to the nearest whole cent.

Any restriction on the exercisability of such Center Financial Stock Option in effect as of the date hereof will continue in full force and effect, and the term, exercisability, and vesting schedule of such Center Financial Stock Option as in effect on the date hereof will remain unchanged. As soon as reasonably practicable following the Closing Date, the Surviving Corporation will deliver to each Person who holds an Assumed Option a

document evidencing the foregoing assumption of such Center Financial Stock Option by the Surviving Corporation. Center Financial and Nara will cooperate and coordinate with respect to any materials to be submitted to the holders of Center Financial Stock Options in connection with any notice required under this Section 2.1(d)(i).

(ii) Assumption of Center Financial Stock Plan. By virtue of the Merger, and without any action by any holders of equity awards, the Surviving Corporation shall, subject to the foregoing, assume the Center Financial Stock Plan (the “Assumed Plan”), with such assumption to be effective as of the Effective Time. Upon and following the Effective Time, the Surviving Corporation will be able to grant stock awards, to the extent permitted by Applicable Legal Requirements and applicable stock exchange listing regulations, under the terms of the Assumed Plan, to issue the reserved but unissued shares of Center Financial Common Stock under the Assumed Plan and the shares that would otherwise return to the Assumed Plan pursuant to the terms thereof, except that immediately upon the Effective Time, all references to a number of shares of Center Financial Common Stock will be (A) changed to references to Nara Common Stock and (B) converted to a number of shares of Nara Common Stock equal to the product of the number of shares of Center Financial Common Stock stated in the Center Financial Stock Plan multiplied by the Exchange Ratio, rounded down to the nearest whole share. The board of directors of the Surviving Corporation (or a committee thereof) shall, effective as of the Effective Time, become the administrator of the Assumed Plan.

(iii) Center Financial Restricted Shares. At the Effective Time, each Center Financial Restricted Share then outstanding shall be assumed by Nara. Subject to, and in accordance with, the terms of the Center Financial Stock Plan and any applicable award or other agreement, each award of Center Financial Restricted Shares then outstanding shall be converted into the number of shares of Nara Common Stock equal to the number of shares of Center Financial Common Stock subject to the Center Financial Restricted Share immediately prior to the Effective Time multiplied by the Exchange Ratio (rounded down to the nearest whole share of Nara Common Stock) (the “Assumed Restricted Shares”). Except as specifically provided in the preceding sentence, following the Effective Time, each Assumed Restricted Shares shall otherwise be subject to the same restrictions, terms and conditions as were applicable to such shares immediately prior to the Effective Time. Center Financial and Nara shall take all steps necessary to cause the foregoing provisions of this Section 2.1(d)(iii) to occur, including but not limited to delivering all required notices. Center Financial and Nara will cooperate and coordinate with respect to any materials to be submitted to the holders of Center Financial Restricted Shares in connection with any notice required under this Section 2.1(d)(iii).

(iv) Violation of Applicable Legal Requirements. No provision of Sections 2.1(d)(i), (ii) or (iii) shall be implemented with respect to an individual if such implementation would violate Applicable Legal Requirements, including those applicable to the Troubled Asset Relief Program.

(e) Warrant. The Warrant issued on December 12, 2008 to the United States Department of the Treasury in connection with the issuance of the Center Financial Series A Preferred Stock (the “Center Financial TARP Warrant”) shall, by virtue of the Merger and without any action on the part of any Person, cease to be a warrant to purchase Center Financial Common Stock and will become, automatically in accordance with its terms, a warrant to purchase Nara Common Stock, and, by virtue of the Merger and without any action on the part of any Person, Nara will assume such warrant subject to its terms; provided, however, that after the Effective Time:

(i) the number of shares of Nara Common Stock purchasable upon exercise of the Center Financial TARP Warrant will equal the product of (x) the number of shares of Center Financial Common Stock that were purchasable pursuant to the Center Financial TARP Warrant immediately before the Effective Time and (y) the Exchange Ratio, rounded to the nearest one-hundredth (1/100th) of a share; and

(ii) the per share exercise price for the Center Financial TARP Warrant will equal the quotient of (x) the per share exercise price of the Center Financial TARP Warrant in effect immediately before the Effective Time and (y) the Exchange Ratio, rounded to the nearest one-tenth (1/10th) of a cent.

(f) Dissenters’ Rights. Notwithstanding anything in this Agreement to the contrary, shares of Center Financial Stock that have not been voted in favor of approving the principal terms of the Merger and with respect to which dissenters’ rights shall have been properly demanded and may properly be exercised in accordance with the CGCL shall not be converted as set forth in Section 2.1(b) at or after the Effective Time unless and until the holder of such shares withdraws such holder’s demand for appraisal in accordance with Applicable Legal Requirements or becomes ineligible for such appraisal, at which time such shares shall be converted as set forth in Section 2.1(b), without interest. Center Financial shall give Nara (i) prompt notice of any written demands for appraisal, withdrawals of demands for appraisal and any other instruments in respect thereof received by Center Financial prior to the Effective Time and (ii) the opportunity to participate in all negotiations and proceedings with respect to demands for appraisal. Without the prior written consent of Nara, Center Financial shall not make any payment with respect to any demands for appraisal and shall not settle or offer to settle any such demands.

(g) Nara Capital Stock. Each share of Nara Common Stock and each share of Nara Preferred Stock shall remain outstanding without change following the Effective Time as shares of the Surviving Corporation, except as provided in Section 2.1(a).

2.2 Exchange of Certificates.

(a) Exchange Agent. As of the Effective Time, Nara shall deposit or make available to a bank or trust company designated by Nara and reasonably acceptable to Center Financial (the “Exchange Agent”), for the benefit of the holders of Center Financial Common Stock for exchange in accordance with this Article II, (i) certificates or, at the option of Nara, evidence of shares in book entry form (collectively “Nara Certificates”) representing the shares

of Nara Common Stock issuable pursuant to Section 2.1 in exchange for such shares of Center Financial Common Stock and (ii) sufficient cash to pay cash in lieu of fractional shares in accordance with Section 2.2(e).

(b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, the Exchange Agent shall mail to each holder of shares of Center Financial Common Stock of record immediately prior to the Effective Time whose shares were converted into shares of Nara Common Stock pursuant to Section 2.1 (i) a letter of transmittal (which shall specify that, with respect to Center Financial Certificates, delivery shall be effected and risk of loss and title to the Center Financial Certificates shall pass, only upon delivery of the Center Financial Certificates and such letter of transmittal to the Exchange Agent, and which shall be in such form and have such other provisions as Nara and Center Financial may reasonably specify) and (ii) instructions for use in effecting the surrender of the Center Financial Certificates or Center Financial Common Stock held in book entry form, as applicable, in exchange for Nara Certificates representing the number of whole shares of Nara Common Stock into which such Center Financial Common Stock has been so converted. Upon surrender of a Center Financial Certificate for cancellation to the Exchange Agent together with such letter of transmittal or submission of a letter of transmittal in respect of shares of Center Financial Common Stock in book entry form, as applicable, duly executed, and such other documents as the Exchange Agent may reasonably require, the holder of such Center Financial Common Stock shall be entitled to receive in exchange therefor a Nara Certificate representing that number of whole shares of Nara Common Stock, which such holder has the right to receive in respect of the Center Financial Common Stock surrendered pursuant to the provisions of this Article II (after taking into account all shares of Center Financial Common Stock then held by such holder), and the Center Financial Common Stock so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of Center Financial Common Stock which is not registered in the transfer records of Center Financial, a Nara Certificate representing the proper number of shares of Nara Common Stock may be issued to a transferee if a duly executed letter of transmittal accompanied, in the case of Center Financial Common Stock in certificated form, by the relevant Center Financial Certificate representing such Center Financial Common Stock, is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. Until surrendered as contemplated by this Section 2.2, each Center Financial Certificate and each book entry in respect of Common Stock in book entry form shall be deemed at any time after the Effective Time to represent only the Nara Common Stock into which such shares of Center Financial Common Stock have been converted as provided in this Article II and the right to receive upon such surrender cash in lieu of any fractional shares of Nara Common Stock, if applicable, as contemplated by this Section 2.2.

(c) Distributions with Respect to Unexchanged Shares. No dividends or other distributions declared or made with respect to Nara Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Center Financial Common Stock with respect to the shares of Nara Common Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder of unsurrendered Center Financial Common Stock pursuant to Section 2.2(e), until the holder

of such Center Financial Common Stock shall have complied with the exchange procedures set forth in Section 2.2(b). Subject to the effect of Applicable Legal Requirements, following the surrender of any such Center Financial Common Stock, there shall be paid to the holder of whole shares of Nara Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender the amount of any cash payable with respect to a fractional share of Nara Common Stock to which such holder is entitled pursuant to Section 2.2(e), if applicable, and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid (but withheld pursuant to the immediately preceding sentence) with respect to such whole shares of Nara Common Stock, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such whole shares of Nara Common Stock.

(d) No Further Ownership Rights. All shares of Nara Common Stock issued upon conversion of shares of Center Financial Common Stock in accordance with the terms hereof (in each case, including any cash paid pursuant to Section 2.2(c) or 2.2(e)) and all shares of Nara Series B Preferred Stock issued upon conversion of shares of Center Financial Series A Preferred Stock in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Center Financial Common Stock or Center Financial Series A Preferred Stock, respectively; subject, however, to the Surviving Corporation’s obligation to pay any dividends or make any other distributions with a record date prior to the Effective Time which may have been declared or made by Center Financial on such shares of Center Financial Series A Preferred Stock in accordance with the terms of this Agreement on or prior to the Effective Time and which remain unpaid at the Effective Time, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Center Financial Common Stock or Center Financial Series A Preferred Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Center Financial Certificate or letter of transmittal in respect of shares of Center Financial Common Stock in book entry form, as applicable, is presented to the Surviving Corporation for any reason, the Center Financial Common Stock represented thereby or referred to therein shall be cancelled and exchanged as provided in this Article II.

(e) No Fractional Shares. No certificates or scrip representing fractional shares of Nara Common Stock shall be issued upon the surrender for exchange of Center Financial Common Stock, and such fractional share interests will not entitle the owner thereof to vote or to any rights of a stockholder of the Surviving Corporation. In lieu thereof, upon surrender of the applicable Center Financial Common Stock by submission of a letter of transmittal to the Exchange Agent accompanied, in the case of Center Financial Common Stock in certificated form, by the applicable Center Financial Certificates, the Exchange Agent shall pay each holder of such Center Financial Common Stock an amount in cash equal to the product obtained by multiplying (i) the fractional share interest to which such holder (after taking into account all shares of Center Financial Common Stock held at the Effective Time by such holder) would otherwise be entitled by (ii) the closing price on NASDAQ, as reported on the NASDAQ website at the close of NASDAQ’s regular session of trading, for a share of Nara Common Stock on the last trading day immediately preceding the Effective Time.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the stockholders of Center Financial for six months after the Effective Time shall be delivered to the Surviving Corporation, upon demand, and any holders of Center Financial Common Stock who have not theretofore complied with this Article II shall thereafter look only to the Surviving Corporation for payment of their claim for Nara Common Stock, any cash in lieu of fractional shares of Nara Common Stock and any dividends or distributions with respect to Nara Common Stock.

(g) No Liability. None of Nara, Center Financial or the Surviving Corporation shall be liable to any holder of shares of Center Financial Common Stock or to any holder of shares of Center Financial Series A Preferred Stock for shares of Nara Common Stock or Nara Series B Preferred Stock, as applicable, or dividends or distributions with respect thereto or cash from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

(h) Withholding. Nara shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Center Financial Common Stock or to any holder of shares of Center Financial Series A Preferred Stock such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code and the rules and regulations promulgated thereunder, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld by Nara, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Center Financial Common Stock or Center Financial Series A Preferred Stock, as applicable, in respect of which such deduction and withholding was made by Nara.

(i) Center Financial Series A Preferred Stock. The Parties shall contact the holder of the Center Financial Series A Preferred Stock prior to the Closing Date to make arrangements reasonably acceptable to such holder for the exchange of such holder’s shares of such stock after the Effective Time.

2.3 Reservation of Right to Revise Structure. Prior to the Effective Time, the Parties shall have the right to change the method of effecting the Merger and/or the Bank Merger to an alternative structure mutually agreed by the Parties, including by re-structuring the transactions contemplated hereby and under the Bank Merger Agreement to provide for the merger of Nara with and into Center Financial, with Center Financial being the surviving corporation, the merger of Nara Bank with and into Center Bank, with Center Bank being the surviving bank, or both; provided, however, that any actions taken pursuant to this Section 2.3 shall not (a) alter or change the kind or amount of consideration to be issued to or retained by holders of Center Financial Common Stock, Center Financial Series A Preferred Stock, Nara Common Stock or Nara Series B Preferred Stock, as compared with what they would otherwise receive or retain pursuant to this Agreement, and holders of Center Financial Common Stock and holders of Nara Common Stock shall receive 45% and 55%, respectively, of the outstanding shares of common stock of the Surviving Corporation after the Merger is consummated, (b) adversely affect the tax consequences of the transaction to any such holder, (c) materially delay receipt of any Requisite Regulatory Approval, or (d) otherwise cause any closing condition not to be capable of being fulfilled (unless duly waived by the Party entitled to

the benefits thereof). If the Parties mutually agree to change the structure of the Merger and/or Bank Merger, the Parties shall execute an appropriate amendment to this Agreement and/or the Bank Merger Agreement, as applicable, in order to reflect the change in structure; provided, however, that any such amendment shall not otherwise substantially affect the economic and other rights and obligations of the Parties or their respective shareholders.

least five business days prior to each meeting of the board of directors of a Target Party, at which such board of directors will consider and determine whether any such offer constitutes a Superior Proposal, the Target Party provides the other Party with a written notice specifying the date and time of such meeting, the reasons for holding such meeting, the terms and conditions of the offer that is the basis of the potential action by the board of directors of the Target Party (including a copy of any draft definitive agreement reflecting the offer) and the identity of the Person making the offer (it being agreed that any change to the terms and conditions of such offer shall require a new notice and five business day period); (E) such board of directors determines in good faith, after obtaining and taking into account the advice of a financial advisor of nationally recognized reputation and its outside legal counsel, that such offer constitutes a Superior Proposal; (F) such board of directors does not effect, or cause the Target Party to effect, a Change in Recommendation at any time within five business days after the other Party receives written notice from the Target Party confirming that such board of directors has determined that such offer is a Superior Proposal and intends to effect a Change in Recommendation; (G) during such five business day period, if requested by such other Party, the Target Party engages in good faith negotiations with such other Party to amend this Agreement in such a manner that the offer that was determined to constitute a Superior Proposal no longer constitutes a Superior Proposal; (H) at the end of such five business day period, such offer has not been withdrawn and continues to constitute a Superior Proposal (taking into account any changes to the terms of this Agreement proposed by the other Party as a result of the negotiations required by clause (G) or otherwise); and (I) the board of directors of the Target Party reasonably determines in good faith, after obtaining and taking into account the advice of its outside legal counsel that, in light of such Superior Proposal, a Change in Recommendation is required in order for such board of directors to comply with its fiduciary duties to its stockholders under the Applicable Legal Requirements; or

(ii) if: (A) a material development or change in circumstances occurs (that is not an Acquisition Proposal) or arises after the date of this Agreement that was neither known to Center Financial or Nara or any of their respective executive officers, directors, advisors and representatives nor reasonably foreseeable by Center Financial or Nara or any of their respective executive officers, directors, advisors and representatives as of the date of this Agreement (such material development or change in such circumstances being referred to herein as an “Intervening Event”); (B) at least five business days prior to each meeting of the Center Financial Board or the Nara Board at which such board of directors intends to consider whether such Intervening Event requires such board of directors to effect or cause Center Financial (in the case of the Center Financial Board) or Nara (in the case of the Nara Board) to effect, a Change in Recommendation, the Party whose board of directors is to meet for such purpose provides the other Party with a written notice specifying the date and time of such meeting and the reasons for holding such meeting, including a reasonably detailed explanation of the Intervening Event (it being agreed that any material change in such Intervening Event shall require a new notice and five business day period); (C) during such five business day period, if requested by the Party so notified, the Party whose board of directors is to meet for such purpose engages in good faith negotiations with the Party so notified to amend this Agreement in a manner that obviates the need to effect or cause

a Change in Recommendation as a result of such Intervening Event; and (D) the board of directors that is considering whether to effect a Change in Recommendation reasonably determines in good faith, after obtaining and taking into account the advice of outside legal counsel, that, in light of such Intervening Event, a Change in Recommendation is required in order for such board of directors to comply with its fiduciary duties to its stockholders under Applicable Legal Requirements.

5.2 Access to Information.

(a) Upon reasonable notice, Center Financial and Nara shall each (and shall cause each of their respective Subsidiaries to) afford to the representatives of the other, access, during normal business hours during the period prior to the Effective Time, to all its properties, books, contracts and records and, during such period, each of Center Financial and Nara shall (and shall cause each of their respective Subsidiaries to) make available to the other (i) a copy of each report, schedule, registration statement and other document filed or received by it during such period pursuant to the requirements of federal or state securities laws, federal or state banking laws or the rules and regulations of self regulatory organizations (other than reports or documents which such Party is not permitted to disclose under Applicable Legal Requirements) and (ii) all other information concerning its business, properties and personnel as such other Party may reasonably request. Neither Party nor any of its Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or prejudice the rights of its customers, jeopardize the attorney-client privilege of the institution in possession or control of such information or contravene any law, rule, regulation, order, judgment, decree or binding agreement entered into prior to the date of this Agreement. The Parties will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

(b) The Parties will hold any such information which is nonpublic in confidence to the extent required by, and in accordance with, the provisions of the letter dated as of October 8, 2010, among Center Financial Bank, Center Financial, Nara Bank and Nara (the “Confidentiality Agreement”), which Confidentiality Agreement will remain in full force and effect.

(c) No such investigation by either Nara or Center Financial shall affect the representations and warranties of the other.

5.3 Reasonable Best Efforts.

(a) Each of Center Financial and Nara shall, and shall cause its Subsidiaries to, use all reasonable best efforts (i) to take, or cause to be taken, all actions necessary to comply promptly with all Applicable Legal Requirements which may be imposed on such Party or its Subsidiaries with respect to the Merger and to consummate the Merger, the Bank Merger and the other transactions contemplated by this Agreement as promptly as practicable, and (ii) to obtain (and to cooperate with the other Party to obtain) any consent, authorization, order or approval of, or any exemption by, any Governmental Entity and/or any other public or private third party which is required to be obtained or made by such

Party or any of its Subsidiaries pursuant to Applicable Legal Requirements or any contract or other obligation in connection with the Merger and the transactions contemplated by this Agreement; provided, however, that a Party shall not be obligated to take any action pursuant to the foregoing if the taking of such action or such compliance or the obtaining of such consent, authorization, order, approval or exemption will result in a condition or restriction on such Party or on the Surviving Corporation having an effect of the type referred to in Section 6.1(f). In furtherance and not in limitation of the Parties’ obligations under this Section 5.3, each of the Parties further agrees as follows:

(i) As soon as practicable after the date hereof, each of Center Financial and Nara shall, and shall cause its Subsidiaries to, use all reasonable best efforts to prepare all necessary documentation and effect all necessary filings in order to obtain the Requisite Regulatory Approvals.

Center Financial and Nara shall have the right to review in advance all filings made in connection with the transactions contemplated by this Agreement with any Governmental Entity (other than with regard to information reasonably considered confidential by the providing Party).

In furtherance of the foregoing, Center Financial and Nara shall provide each other reasonable advance notice of any such hearing, proceeding, meeting, conference or similar event.

(b) Nara agrees to execute and deliver, or cause to be executed and delivered by or on behalf of the Surviving Corporation, at or prior to the Effective Time, supplemental indentures and other instruments required for the due assumption of Center Financial’s outstanding debt, guarantees and other securities to the extent required by the terms of such debt, guarantees and securities and the instruments and agreements relating thereto, including under the Indenture dated as of December 30, 2003 between ▇▇▇▇▇ Fargo Bank, National Association, as trustee, and Center Financial, relating to the issuance by Center Financial of its Junior Subordinated Debt Securities due January 7, 2034.

(c) Each of Center Financial and Nara and their respective boards of directors shall, if any state takeover statute or similar statute becomes applicable to this Agreement, the Merger or any other transactions contemplated hereby, use all reasonable best efforts to ensure that the Merger and the other transactions contemplated by this Agreement 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, the Merger and the other transactions contemplated hereby.

5.4 Acquisition Proposals.

(a) Each of Nara and Center Financial agrees that neither it nor any of its Subsidiaries nor any of the officers and directors of it or its Subsidiaries shall, and that it shall use its reasonable best efforts to cause its and its Subsidiaries’ employees, agents and representatives (including any investment banker, attorney or accountant retained by it or any of its Subsidiaries) not to, directly or indirectly, (i) initiate, solicit, encourage or knowingly facilitate any inquiries or the making of any proposal or offer with respect to, or a transaction to effect, a merger, reorganization, share exchange, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving it or any of its Subsidiaries or any purchase or sale of 20% or more of the consolidated assets (including stock of its Subsidiaries) of it and its Subsidiaries, taken as a whole, or any purchase or sale of, or tender or exchange offer for, its voting securities that, if consummated, would result in any Person (or the stockholders of such Person) beneficially owning securities representing 20% or more of the total voting power of it (or of the surviving parent entity in such transaction) or of any of its Subsidiaries (any such proposal, offer or transaction (other than a proposal or offer made by the other Party or an affiliate thereof) being hereinafter referred to as an “Acquisition Proposal”), (ii) have any discussions with or provide any confidential information or data to any Person relating to an Acquisition Proposal, or engage in any negotiations concerning an Acquisition Proposal, or knowingly facilitate any effort or attempt to make or implement an Acquisition Proposal, or (iii) approve or recommend, or propose to approve or recommend, or execute or enter into, any letter of intent, agreement in principle, merger agreement, asset purchase or share exchange agreement, option agreement or other similar agreement related to any Acquisition Proposal or propose or agree to do any of the foregoing.

(b) (i) Notwithstanding the foregoing, the board of directors of each Party shall be permitted, prior to its respective meeting of stockholders to be held pursuant to Section 5.1, and subject to material compliance by such Party with the other terms of this Section 5.4 and to such Party first entering into a confidentiality agreement with the Person making the

Acquisition Proposal described below having provisions that are no less favorable to such Party than those contained in the Confidentiality Agreement, to engage in discussions and negotiations with, or provide any nonpublic information or data to, any Person in response to an unsolicited bona fide written Acquisition Proposal by such Person first made after the date of this Agreement which such Party’s board of directors concludes in good faith constitutes or is reasonably likely to result in a Superior Proposal.

(ii) Each Party shall notify the other Party promptly (but in no event later than 24 hours) after receipt of any Acquisition Proposal, or any request for nonpublic information relating to such Party or any of its Subsidiaries by any Person that informs such Party or any of its Subsidiaries that it is considering making, or has made, an Acquisition Proposal, or any inquiry from any Person seeking to have discussions or negotiations with such Party relating to a possible Acquisition Proposal. Such notice shall be made orally and confirmed in writing, and shall indicate the identity of the Person making the Acquisition Proposal, inquiry or request and the material terms and conditions of any inquiries, proposals or offers (including a copy thereof if in writing and any related documentation or correspondence). Each Party shall also promptly, and in any event within 24 hours, notify the other Party, orally and in writing, if it enters into discussions or negotiations concerning any Acquisition Proposal or provides nonpublic information or data to any Person in accordance with this Section 5.4(b) (and shall promptly provide to the other Party copies of all material nonpublic information so provided not previously provided to the other Party) and shall keep the other Party promptly and fully informed of the status and terms of any such proposals, offers, discussions or negotiations on a current basis, including by providing within 24 hours of receipt a copy of all material documentation or correspondence relating thereto (including copies of all changes in any terms).

(iii) Nothing contained in this Section 5.4 shall prohibit either Party or its Subsidiaries from taking and disclosing to its stockholders a position required by Rule 14e-2(a) or Rule 14d-9 promulgated under the Exchange Act; provided, however, that compliance with such rules shall not in any way limit or modify the effect that any action taken pursuant to such rules has under any other provision of this Agreement, including Section 7.1(d) or 7.1(e), as applicable.

(c) Each of Nara and Center Financial agrees that (i) it will and will cause its Subsidiaries, and its and their officers, directors, agents, representatives and advisors to, cease immediately and terminate any and all existing activities, discussions or negotiations with any third parties conducted heretofore with respect to any Acquisition Proposal, and will promptly request each Person, if any, that has heretofore executed a confidentiality agreement with such Party in connection with the consideration of any Acquisition Proposal, to return or destroy all confidential information or data heretofore furnished to such Person, (ii) it shall enforce (and not release any third party from or waive) any provisions of, any confidentiality, standstill or similar agreement to which it or any of its Subsidiaries is a party with respect to any Acquisition Proposal and (iii) it will not take any action to render inapplicable or to exempt any Person from Section 203 of the DGCL or any other antitakeover legislation. Each of Nara and Center Financial agrees that it will use reasonable best efforts to inform its and its Subsidiaries’

respective directors, executive officers, key employees, agents and representatives of the obligations undertaken in this Section 5.4.

(d) Nothing in this Section 5.4 shall (i) permit either Party to terminate this Agreement or (ii) affect any other obligation of the Parties under this Agreement. Neither Party shall submit to the vote of its stockholders any Acquisition Proposal other than the Merger.

(e) Any disclosure (other than a “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act) made pursuant to Section 5.4(b)(iii) shall be deemed to be a Change in Recommendation by Center Financial or Nara, as the case may be, unless the board of directors of the Party making such disclosure expressly reaffirms its Board Recommendation to its stockholders in favor of the approval of the principal terms of the Merger or the adoption of this Agreement, as applicable.

(f) The provisions of this Section 5.4 shall be deemed, as between the Parties, to apply to each Party, its Subsidiaries and its and its Subsidiaries’ directors and employees, agents and representatives to the same extent as such provisions apply to the respective Parties, and each Party shall be responsible for any breach of such provisions by any of its or its Subsidiaries’ directors, employees, agents or representatives.

5.5 Stock Exchange Listing. Nara shall use all reasonable efforts to cause the shares of Nara Common Stock to be issued in the Merger to be approved for listing on NASDAQ, subject to official notice of issuance, prior to the Closing Date.

5.6 Employee Benefit Plans and Employee Matters.

(a) Nara and Center Financial agree that, except as otherwise provided herein (including as set forth in Section 5.6(a) of the Center Financial Disclosure Schedule) and unless otherwise mutually determined, the Nara Benefit Plans and Center Financial Benefit Plans in effect at the date of this Agreement shall remain in effect after the Effective Time with respect to employees covered by such plans at the Effective Time, and the Surviving Corporation shall as promptly as practical formulate Benefit Plans for the Surviving Corporation and its Subsidiaries, with respect both to employees who were covered by the Nara Benefit Plans and Center Financial Benefit Plans at the Effective Time and employees who were not covered by such plans at the Effective Time, that provide benefits for services on a basis that does not discriminate between employees who were covered by the Nara Benefit Plans and employees who were covered by the Center Financial Benefit Plans. Center Financial shall adopt such amendments to the Center Financial Benefit Plans as requested by Nara to implement the foregoing and to avoid the duplication of benefits. Notwithstanding any other provision of this Agreement, if requested by Nara, Center Financial shall terminate the Center Financial Severance Program (Revised August 12, 2009) and any other plans, policies, programs or arrangements providing severance benefits, such termination to be effective prior to the Effective Date.

(b) Center Financial and Nara further agree that, to the extent that employees of Center Financial and its Subsidiaries or Nara and its Subsidiaries are covered by Benefit Plans of the Surviving Corporation, the Surviving Corporation shall: (i) provide employees of Center

Financial and its Subsidiaries and employees of Nara and its Subsidiaries credit for all years of service with Center Financial or any of its Subsidiaries and their predecessors, or Nara and any of its Subsidiaries and their predecessors, as applicable, prior to the Effective Time for the purpose of eligibility and vesting, (ii) cause any and all pre-existing condition limitations (to the extent such limitations did not apply to a pre-existing condition under comparable Benefit Plans applicable to the individual immediately prior to the Closing Date) and eligibility waiting periods under group health plans of the Surviving Corporation to be waived with respect to employees of Center Financial and its Subsidiaries and Nara and its Subsidiaries who remain as employees of the Surviving Corporation or its Subsidiaries (and their eligible dependents) and (iii) cause to be credited, for purposes of the Surviving Corporation’s health plans, any deductibles or out-of-pocket expenses incurred by employees of Center Financial and its Subsidiaries and Nara and its Subsidiaries and their beneficiaries and dependents during the portion of the calendar year prior to their participation in the Surviving Corporation’s health plans with the objective that there be no double counting during the year in which the Closing Date occurs of such deductibles or out-of-pocket expenses. Notwithstanding the preceding sentence, to the extent that the Surviving Corporation reasonably determines that legal, administrative, or other impediments make compliance with the preceding sentence not reasonably practicable or that such compliance would result in the duplication of benefits, the Surviving Corporation shall have no obligations or liabilities with respect to the requirements of the preceding sentence. Center Financial and Nara hereby further agree that, except as otherwise specified in this Agreement, the Surviving Corporation shall honor, or cause to be honored, in accordance with their terms, all vested or accrued benefit obligations to, and contractual rights of, current and former employees of Center Financial and its Subsidiaries and Nara and its Subsidiaries. Without limiting the generality of the foregoing, Nara shall recognize and honor all unused sick leave and unused vacation accrued by the employees of Center Financial and its Subsidiaries as of the Effective Time notwithstanding any limitations on sick leave accruals or carry-overs or vacation accruals applicable under Nara’s sick leave or vacation accrual policies.

5.7 Center Financial Stock Option and Center Financial Restricted Shares.

(a) Center Financial shall deliver to Nara the Section 16 Information reasonably in advance of the Effective Time, and the Nara Board, or a committee of Non-Employee Directors thereof (as such term is defined for purposes of Rule 16b-3(d) under the Exchange Act), shall reasonably promptly thereafter and in any event prior to the Effective Time adopt a resolution providing that the receipt by the Center Financial Insiders of Nara Common Stock in exchange for shares of Center Financial Common Stock (including Center Financial Restricted Shares), and of options to purchase Nara Common Stock upon conversion of Center Financial Stock Options, in each case pursuant to the transactions contemplated hereby and to the extent such securities are listed in the Section 16 Information provided by Center Financial to Nara prior to the Effective Time, are intended to be exempt from liability pursuant to Section 16(b) under the Exchange Act such that any such receipt shall be so exempt.

(b) Nara agrees to file with the SEC, no later than 30 days after the Closing Date, a registration statement on Form S-8 (or any successor form) relating to the Nara Common Stock issuable with respect to the Assumed Options and the Assumed Restricted Shares and shall use commercially reasonable efforts to maintain the

effectiveness of such registration statement thereafter for so long as any of Assumed Option or Assumed Restricted Shares remain outstanding.

5.8 Fees and Expenses. Whether or not the Merger is consummated, all costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the Party incurring such expense, except as otherwise provided in Section 7.2 hereof and except that (a) if the Merger is consummated, the Surviving Corporation shall pay, or cause to be paid, any and all property or transfer taxes imposed on either Party in connection with the Merger, and (b) the filing fees and printing and mailing expenses incurred in connection with filing, printing and mailing the Joint Proxy Statement/Prospectus and the Form S-4 shall be shared equally by Nara and Center Financial.

5.9 Governance; Name Change.

(a) Prior to the Effective Time, Nara shall use its reasonable best efforts to adopt the amendment to the By-laws of Nara substantially in the form set forth in Exhibit 1.4 and to effect the requirements and adopt the resolutions referenced therein. On or prior to the Effective Time, Nara shall cause the number of directors that will comprise the board of directors of the Surviving Corporation at the Effective Time to be 14. Of the members of the initial board of directors of the Surviving Corporation at the Effective Time, seven shall be current members of the Nara Board as designated by Nara prior the Effective Time, and seven shall be current members of the Center Financial Board as designated by Center Financial prior to the Effective Time. No other directors or employees of Nara or Center Financial shall be designated to serve on the board of directors of the Surviving Corporation at the Effective Time.

5.10 Indemnification; Directors’ and Officers’ Insurance.

(a) From and after the Effective Time, the Surviving Corporation shall, to the fullest extent permitted by Applicable Legal Requirements, indemnify, defend and hold harmless, and provide advancement of expenses to, each person who is now, or has been at any time prior to the date hereof or who becomes prior to the Effective Time, an officer, director or employee of Center Financial or any of its Subsidiaries (the “Indemnified Parties”) against all losses, claims, damages, costs, expenses, liabilities or judgments or amounts that are paid in settlement of or in connection with any claim, action, suit,

proceeding or investigation based in whole or in part on or arising in whole or in part out of the fact that such person is or was a director, officer or employee of Center Financial or any Subsidiary of Center Financial, and pertaining to any matter existing or occurring, or any acts or omissions occurring, at or prior to the Effective Time, whether asserted or claimed prior to, or at or after, the Effective Time (including matters, acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby) (“Indemnified Liabilities”) to the same extent such persons are indemnified or have the right to advancement of expenses as of the date of this Agreement by Center Financial pursuant to Center Financial’s Articles of Incorporation, By-laws and indemnification agreements, if any, in existence on the date hereof with any directors, officers and employees of Center Financial and its Subsidiaries.

(b) For a period of six years after the Effective Time, the Surviving Corporation shall cause to be maintained in effect the current policies of directors’ and officers’ liability insurance maintained by Center Financial (provided that the Surviving Corporation may substitute therefor policies with a substantially comparable insurer of at least the same coverage and amounts containing terms and conditions which are no less advantageous to the insured) with respect to claims arising from facts or events which occurred at or before the Effective Time; provided, however, that the Surviving Corporation shall not be obligated to make annual premium payments for such insurance to the extent such premiums exceed 250% of the premiums paid as of the date hereof by Center Financial for such insurance (“Center Financial’s Current Premium”), and if such premiums for such insurance would at any time exceed 250% of Center Financial’s Current Premium, then the Surviving Corporation shall cause to be maintained policies of insurance which, in the Surviving Corporation’s good faith determination, provide the maximum coverage available at an annual premium equal to 250% of Center Financial’s Current Premium. In lieu of the foregoing, Center Financial, in consultation with, but only upon the consent of Nara, may obtain on or prior to the Effective Time a six-year “tail” policy or “extended discovery period” under Center Financial’s existing directors and officers insurance policy providing equivalent coverage to that described in the preceding sentence if and to the extent that the same may be obtained for an amount that does not exceed Center Financial’s Current Premium.

(c) The Surviving Corporation shall pay (as incurred) all expenses, including reasonable fees and expenses of counsel, that an Indemnified Party may incur in enforcing the indemnity and other obligations provided for in this Section 5.10.

(d) If the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, to the extent necessary, proper provision shall be made so that the successors and assigns of the Surviving Corporation, as the case may be, shall assume the obligations set forth in this Section 5.10.

(e) The provisions of this Section 5.10 (i) are intended to be for the benefit of, and shall be enforceable by, each Indemnified Party, his or her heirs and representatives and (ii)

are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such Person may have by contract or otherwise.

5.11 Public Announcements. Nara and Center Financial shall use reasonable best efforts (a) to develop a joint communications plan, (b) to ensure that all press releases and other public statements with respect to the transactions contemplated hereby shall be consistent with such joint communications plan, and (c) except in respect of any announcement required by Applicable Legal Requirements or by obligations pursuant to any listing agreement with or rules of any securities exchange, to consult with each other before issuing any press release or, to the extent practical, otherwise making any public statement with respect to this Agreement or the transactions contemplated hereby. In addition to the foregoing, except to the extent disclosed in or consistent with the Joint Proxy Statement/Prospectus in accordance with the provisions of Section 5.1 or as otherwise permitted under Section 4.4, no Party shall issue any press release or otherwise make any public statement or disclosure concerning the other Party or the other Party’s business, financial condition or results of operations without the consent of such other Party, which consent shall not be unreasonably withheld or delayed. Each Party shall provide the other Party with its stockholder lists and allow and facilitate the other Party’s contact with its stockholders and prospective investors and following a Change in Recommendation by Center Financial or Nara, as the case may be, such contacts may be made without regard to the above limitations of this Section 5.11.

5.12 Tax Matters. (a) Center Financial and Nara each shall not, and shall not permit any of their Subsidiaries to, take or cause to be taken any action, whether before or after the Effective Time, which would reasonably be expected to disqualify the Merger as a reorganization within the meaning of Section 368(a) of the Code and (b) Center Financial and Nara each agree to file all tax returns consistent with the treatment of the Merger as a “reorganization” within the meaning of Section 368(a) of the Code.

5.13 Additional Agreements. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full title to all properties, assets, rights, approvals, immunities and franchises of either of the Constituent Corporations, the proper officers and directors of each Party shall take all such necessary action.

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 and, unless the effect of such invalidity or unenforceability would prevent the Parties from realizing the major portion of the economic benefits of the Merger that they currently anticipate obtaining therefrom, shall not render invalid or unenforceable the remaining terms and provisions of this Agreement or affect 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.

8.9 Assignment. Neither this Agreement nor any of the rights, interests or obligations of the Parties hereunder shall be assigned by either of the Parties (whether by operation of law or otherwise) without the prior written consent of the other Party, and any attempt to make any such assignment without such consent shall be null and void. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and permitted assigns.

8.10 Submission to Jurisdiction. Each Party irrevocably submits to the jurisdiction of the state and federal courts located in the State of Delaware, for the purposes of any suit, action or other proceeding arising out of this Agreement or any transaction contemplated hereby. Each Party agrees to commence any action, suit or proceeding relating hereto in such courts. Each Party irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby in such courts, and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

The consent to jurisdiction set forth in this Section 8.10 shall not constitute a

general consent to service of process in the State of Delaware and shall have no effect for any purpose except as provided in this Section 8.10. The Parties agree that a final judgment in any such suit, action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

8.11 Enforcement. The Parties 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 on a timely basis or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to an injunction or other equitable relief, without the necessity of proving actual monetary loss or posting any bond or other security, to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in any court identified in Section 8.10, this being in addition to any other remedy to which they are entitled at law or in equity.

For the avoidance of doubt, in the event that Mr. Ki Suh Park or ▇▇. ▇▇▇▇▇ ▇▇▇ ▇▇▇ ceases to serve as a Director of the Corporation for any reason during the Integration Period, their respective successors as Directors of the Corporation shall be determined in accordance with Article II, Section 9.5.
