The deposit accounts of the bank subsidiary of the Company are insured by the FDIC to the legal maximum, such subsidiary has paid all premiums and assessments required by the FDIC and the regulations thereunder and no proceeding for the termination or revocation of such insurance is pending or, to the knowledge of the Company, threatened.

(xxxii) Internal Control Over Financial Reporting. The Company and each of its Subsidiaries maintains “internal controls over financial reporting” (as such term is defined in Rule 13a-15(f) and 15d-15(f) under the 1934 Act) sufficient to provide reasonable assurance that (A) transactions are executed in accordance with management’s general or specific authorizations; (B) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability; (C) access to assets is permitted only in accordance with management’s general or specific authorization; and (D) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. The Company’s internal control over financial reporting has been evaluated by the management of the Company (including the Company’s Chief Executive Officer and Chief Financial Officer) for effectiveness as of the end of the Company’s most recent fiscal year. Except as disclosed in the General Disclosure Package and the Prospectus, since the end of the Company’s most recent audited fiscal year, there has been (I) no material weakness or significant deficiency in the Company’s internal control over financial reporting (whether or not remediated) and (II) no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

(xxxiii) Disclosure Controls and Procedures. The Company and its Subsidiaries employ disclosure controls and procedures (as such term is defined in Rule 13a-15 under the 1934 Act), which (A) are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the 1934 Act is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms and that material information relating to the Company and its Subsidiaries is made known to the Company’s principal executive officer and principal financial officer by others within the Company and its Subsidiaries to allow timely decisions regarding disclosure, and (B) are effective in all material respects to perform the functions for which they were established. Based on the evaluation of the Company’s and each Subsidiary’s disclosure controls and procedures described above, the Company is not aware of (1) any significant deficiency in the design or operation of internal controls which could adversely affect the Company’s ability to record, process, summarize and report financial data or any material weaknesses in internal controls or (2) any fraud, whether or not material, that involves management or other employees who have a significant role in the Company’s internal controls. Since the most recent evaluation of the Company’s disclosure controls and procedures described above, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls.

(xxxiv) Compliance with the Sarbanes-Oxley Act. There is and has been no failure on the part of the Company or any of the Company’s directors or officers, in their capacities as such, to comply in all material respects with any provision of the Sarbanes-Oxley Act and the rules and regulations promulgated in connection therewith, including Section 402 related to loans and Sections 302 and 906 related to certifications.

(xxxviii) No Stabilization or Manipulation. Neither the Company nor any of its Subsidiaries, nor any affiliates of the Company or its Subsidiaries, has taken, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Securities.

(xxxix) No Unauthorized Use of Prospectus. The Company has not distributed and, prior to the later to occur of (i) the Closing Time and (ii) completion of the distribution of the Securities, will not distribute any prospectus (as such term is defined in the 1933 Act and the 1933 Act Regulations) in connection with the offering and sale of the Securities other than the Registration Statement, any preliminary prospectus, the Prospectus or other materials, if any, permitted by the 1933 Act or by the 1933 Act Regulations and approved by the Underwriters.

(A) The Company has entered into the Agreement and Plan of Merger, dated December 9, 2010, by and between the Company and Center (the “Merger Agreement”). In connection with the transactions contemplated by the Merger Agreement (the “Merger”), the Company conducted a “due diligence” review of the business, financial condition, results of operations and business prospects of Center. Based upon the Company’s review, with respect to Center or the Merger, nothing has come to the Company’s attention that caused it to believe that the Registration Statement, the General Disclosure Package or the Prospectus contained an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

(B) The Merger Agreement has been duly authorized, executed and delivered by the Company and constitutes a valid and binding agreement of the Company and is enforceable against the Company in accordance with its terms. As of the date hereof, nothing has come to the Company’s attention that caused it to believe that Center has the right to terminate the Merger Agreement in accordance with its terms. As of the date hereof, nothing has come to the Company’s attention that caused it to believe that (1) the representations and warranties made in the Merger Agreement and related disclosure schedules by Center were not true and correct as of the date of the Merger Agreement and not true and correct on the date hereof (except that representations and warranties that in their terms speak as of some other date were true and correct as of such date), and (2) the covenants and other agreements of Center set forth in the Merger Agreement have been breached, in a manner such that, with respect to either clause (1) or (2) of this sentence, the Company has the right to terminate the Merger Agreement.

In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to each Underwriter to purchase up to an additional number of shares of Common Stock set forth opposite its name in Annex A hereto, at the price per share set forth in Schedule B, less an amount per share equal to any dividends or distributions declared by the Company and payable on the Initial Securities but not payable on the Option Securities. The option hereby granted will expire 30 days after the date hereof and may be exercised in whole or in part from time to time only for the purpose of covering over-allotments which may be made in connection with the offering and distribution of the Initial Securities upon notice by the Underwriters to the Company setting forth the number of Option Securities as to which the Underwriters are then exercising the option and the time and date of payment and delivery for such Option Securities. Any such time and date of delivery (a “Date of Delivery”) shall be determined by the Underwriters, but shall not be later than seven full business days after the exercise of said option, nor in any event prior to the Closing Time, as hereinafter defined.

(c) Payment. Payment of the purchase price for, and delivery of certificates for, the Initial Securities shall be made at the offices of Sullivan & Cromwell LLP located at 1888 Century Park East, Suite 2100, Los Angeles, California 90067, or at such other place as shall be agreed upon by the Underwriters and the Company, at 9:00 A.M. (Eastern time) on the third (or fourth, if the pricing occurs after 4:30 P.M.

In addition, in the event that any or all of the Option Securities are purchased by the Underwriters, payment of the purchase price for, and delivery of certificates for, such Option Securities shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by the Underwriters and the Company, on each Date of Delivery as specified in the notice from the Underwriters to the Company.

The Company will promptly effect the filings necessary pursuant to Rule 424(b) in the manner and within the time period required by Rule 424(b) (without reliance on Rule 424(b)(8)) and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus. The Company will make every reasonable effort to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment.

(b) Filing of Amendments. The Company will give the Underwriters notice of its intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 462(b)) or any amendment, supplement or revision to either any preliminary prospectus (including the prospectus included in the Registration Statement at the time it became effective) or to the Prospectus, whether pursuant to the 1933 Act, the 1934 Act or otherwise, will furnish the Underwriters with copies of any such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Underwriters or counsel for the Underwriters shall reasonably object.

(c) Delivery of Registration Statements. The Company has furnished or will deliver to the Underwriters and counsel for the Underwriters, without charge, signed copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein) and signed copies of all consents and certificates of experts, and will also deliver to the Underwriters, without charge, a conformed copy of the Registration Statement as originally filed and of each amendment thereto (without exhibits). The copies of the Registration Statement and each amendment thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(d) Delivery of Prospectuses. The Company has delivered to the Underwriters, without charge, as many copies of each preliminary prospectus as the Underwriters reasonably requested, and the Company hereby consents to the use of such copies for purposes permitted by the 1933 Act. The Company will furnish to the Underwriters, without charge, during the period

when the Prospectus is required to be delivered under the 1933 Act or the 1934 Act, such number of copies of the Prospectus (as amended or supplemented) as the Underwriters may reasonably request. The Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(e) Continued Compliance with Securities Laws. The Company will comply with the 1933 Act and the 1933 Act Regulations and the 1934 Act and the 1934 Act Regulations so as to permit the completion of the distribution of the Securities as contemplated in this Agreement and in the Prospectus. If at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Securities, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Company, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include any untrue statements of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare and file with the Commission, subject to Section 3(b), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request. If at any time following issuance of an Issuer-Represented Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer-Represented Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company has promptly notified or will promptly notify the Underwriters and has promptly amended or will promptly amend or supplement, at its own expense, such Issuer-Represented Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(f) Blue Sky Qualifications. The Company will use commercially reasonable efforts, in cooperation with the Underwriters, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Underwriters may designate and to maintain such qualifications in effect for a period of not less than one year from the later of the effective date of the Registration Statement and any Rule 462(b) Registration Statement; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject. In each jurisdiction in which the Securities have been so qualified, the Company will file such statements and reports as may be required by the laws of such jurisdiction to continue such qualification in effect for a period of not less than one year from the effective date of the Registration Statement and any Rule 462(b) Registration Statement. The Company will also supply the Underwriters with such information as is necessary for the determination of the legality of the Securities for investment under the laws of such jurisdiction as the Underwriters may request.

The Company shall promptly notify the Underwriters of any earnings releases, news or events that may give rise to an extension of the initial restricted period.

(k) Reporting Requirements. The Company, during the period when the Prospectus is required to be delivered under the 1933 Act or the 1934 Act, will file all documents required to be filed with the Commission pursuant to the 1934 Act within the time periods required by the 1934 Act and the 1934 Act Regulations.

(m) Permitted Free Writing Prospectus. The Company represents and agrees that, unless it obtains the prior consent of the Underwriters, it has not made and will not make any offer relating to the Securities that would constitute an “issuer free writing prospectus,” as defined in Rule 433, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Underwriters is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated or agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 applicable to any Permitted Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping.

At the request of the Underwriters, the Company will direct the transfer agent to place a stop transfer restriction upon such securities for such period of time. Should the Company release, or seek to release, from such restrictions any of the Reserved Securities, the Company agrees to reimburse the Underwriters for any reasonable expenses (including, without limitation, legal expenses) they incur in connection with such release.

(a) Indemnification of Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, its affiliates (as such term is defined in rule 501(b) under the 1933 Act) (“Affiliates”), its selling agents, and each person, if any, who controls such Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the Rule 430B Information, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus, any Issuer-Represented Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Underwriters), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by the Underwriters expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430B Information, or any preliminary prospectus, any Issuer-Represented Free Writing Prospectus, or the Prospectus (or any amendment or supplement thereto); provided that the parties acknowledge and agree that the only written information that the Underwriters have furnished to the Company specifically for inclusion in the Registration Statement, preliminary prospectus and Prospectus (or any amendment or supplement thereto) are the concession and reallowance figures appearing in the Prospectus in the section entitled “Underwriting” and the information contained under the captions “Underwriting – Price stabilization and short positions” (the “Underwriters’ Information”).

(b) Indemnification of Company, Directors and Officers. Each Underwriter agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Rule 430B Information, or any preliminary prospectus, or any Issuer-Represented Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriters’ Information.

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by the Underwriters, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any

one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement Without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) or settlement of any claim in connection with any violation referred to in Section 6(e) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

(e) Indemnification for Reserved Securities. In connection with the offer and sale of the Reserved Securities, the Company agrees to indemnify and hold harmless the Underwriters, their Affiliates and selling agents and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act, from and against any and all loss, liability, claim, damage and expense (including, without limitation, any legal or other expenses reasonably incurred in connection with defending, investigating or settling any such action or claim), as incurred, (i) arising out of the violation of any applicable laws or regulations of foreign jurisdictions where Reserved Securities have been offered; (ii) arising out of any untrue statement or alleged untrue statement of a material fact contained in any prospectus wrapper or other material prepared by or with the consent of the Company for distribution to Invitees in connection with the offering of the Reserved Securities or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; (iii) caused by the failure of any Invitee to pay for and accept delivery of Reserved Securities which have been orally confirmed for purchase by any Invitee by 9:00 a.m. Eastern Time on the first business day after the date of the Agreement; or (iv) related to, or arising out of or in connection with, the offering of the Reserved Securities.

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other

hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions, or in connection with any violation of the nature referred to in Section 6(e) hereof, which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, on the one hand, and the total underwriting discount and commissions received by the Underwriters, on the other hand, in each case as set forth on the cover of the Prospectus.

The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission, or any violation of the nature referred to in Section 6(e) hereof.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, the Underwriters shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by them and distributed to the public were offered to the public exceeds the amount of any damages which the Underwriters have otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and such Underwriter’s Affiliates and selling agents shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company.

SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any (i) investigation made by or on behalf of either Underwriter or its Affiliates or selling agents, any person controlling such Underwriter, its officers or directors, or by or on behalf of the Company, and (ii) delivery of and payment for the Securities.

(a) Termination; General. The Underwriters may terminate this Agreement, by notice to the Company, at any time at or prior to Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the preliminary prospectus, the General Disclosure Package or the Prospectus, any material adverse change, or any development involving a prospective material adverse change, in the condition, financial or otherwise, or in the earnings or business affairs of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if, since the time of execution of this Agreement, there has occurred any material adverse change in the financial markets in the United States, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, including without limitation as a result of terrorist activities, in each case the effect of which is such as to make it, in the judgment of the Underwriters, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or Nasdaq, or if trading generally on the American Stock Exchange or the New York Stock Exchange or on Nasdaq has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, FINRA or any other governmental authority, or (iv) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (v) if a banking moratorium has been declared by either Federal, New York, California or Delaware authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 6, 7 and 8 shall survive such termination and remain in full force and effect.

SECTION 10. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

(xviii) The execution, delivery and performance of the Underwriting Agreement and the consummation of the transactions contemplated in the Underwriting Agreement, in the Merger Agreement and in the Registration Statement (including the issuance and sale of the Securities and the use of the proceeds from the sale of the Securities as described in the Prospectus under the caption “Use Of Proceeds”) and compliance by the Company with its obligations under the Underwriting Agreement and under the Merger Agreement do not and will not, whether with or without the giving of notice or lapse of time or both, conflict with or constitute a breach of, or default or Repayment Event under or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any Subsidiary pursuant to any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or any other agreement or instrument, known to us, to which the Company or any Subsidiary is a party or by which it or any of them may be bound, or to which any of the property or assets of the Company or any Subsidiary is subject (except for such conflicts, breaches or defaults or liens, charges or encumbrances that would not, individually or in the aggregate, have a Material Adverse Effect), nor will such action result in any violation of the provisions of the charter or by-laws of the Company or any Subsidiary, or any applicable law, statute, rule, regulation, judgment, order, writ or decree, known to us, of any Governmental Entity having jurisdiction over the Company or any Subsidiary or any of their respective properties, assets or operations.

(xix) The Company is not an “investment company” or an entity “controlled” by an “investment company,” as such terms are defined in the 1940 Act.

In rendering such opinion, such counsel may rely, as to matters of fact (but not as to legal conclusions), to the extent they deem proper, on certificates of responsible officers of the Company and public officials.

Nothing has come to our attention that causes us to believe that the Registration Statement or any amendment thereto, including the Rule 430B Information, except for financial statements and schedules and other financial data included or incorporated by reference therein or omitted therefrom, as to which we make no statement, at the time such Registration Statement or any such amendment became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or that the Prospectus or any amendment or supplement thereto (except for financial statements and schedules and other financial data included or incorporated by reference therein or omitted therefrom, as to which we make no statement), at the time the Prospectus was issued, at the time any such amended or supplemented prospectus was issued or at the Closing Time, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

Nothing has come to our attention that causes us to believe that the documents specified in the General Disclosure Package, except for financial statements and schedules and other financial data included or incorporated by reference therein or omitted therefrom, as to which we make no statement, as of the Applicable Time and as of the Closing Date, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

FORM OF OPINION OF COMPANY’S CORPORATE COUNSEL TO BE DELIVERED PURSUANT TO SECTION 5(c)

(ii) The shares of issued and outstanding capital stock of the Company have been duly authorized and validly issued and are fully paid and non-assessable.

(iii) Except as otherwise disclosed in the Prospectus, all of the issued and outstanding capital stock of each Subsidiary has been duly authorized and validly issued, is fully paid and non-assessable and, to the best of my knowledge, is owned by the Company, directly or through subsidiaries, free and clear of any security interest, mortgage, pledge, lien, encumbrance, claim or equity; none of the outstanding shares of capital stock of any Subsidiary was issued in violation of the preemptive or similar rights of any securityholder of such Subsidiary.

(iv) To the best of my knowledge, neither the Company nor the Bank is in violation of its charter or by-laws and no default by the Company or the Bank exists in the due performance or observance of any material obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, loan agreement, note, lease or other agreement or instrument that is described or referred to in the Registration Statement or the Prospectus or filed or incorporated by reference as an exhibit to the Registration Statement.

In rendering such opinion, such counsel may rely, as to matters of fact (but not as to legal conclusions), to the extent such counsel deems proper, on certificates of responsible officers of the Company and public officials.

The undersigned, a shareholder and an executive officer and/or director of [Nara Bancorp, Inc., a Delaware corporation (the “Company”)][Center Financial Corporation, a California corporation (“Center”), and an anticipated executive officer and/or director of Nara Bancorp, Inc., a Delaware corporation (the “Company”), after the consummation of the merger between the Company and Center], understands that Keefe, Bruyette & Woods, Inc. and D.A. Davidson & Co. (the “Underwriters”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with the Company providing for the public offering of shares (the “Securities”) of the Company’s common stock, $0.001 par value per share (the “Common Stock”). In recognition of the benefit that such an offering will confer upon the undersigned as [a][an anticipated] shareholder and an executive officer and/or director of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned agrees with each underwriter to be named in the Underwriting Agreement that, during a period of 90 days from the date of the Underwriting Agreement, the undersigned will not, without the prior written consent of the Underwriters, directly or indirectly, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, or otherwise dispose of or transfer any shares of the Company’s Common Stock or any securities convertible into or exchangeable or exercisable for Common Stock, whether now owned or hereafter acquired by the undersigned or with respect to which the undersigned has or hereafter acquires the power of disposition, or file any registration statement under the Securities Act of 1933, as amended, with respect to any of the foregoing or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Common Stock, whether any such swap or transaction is to be settled by delivery of Common Stock or other securities, in cash or otherwise. In the event that either (i) during the period that begins on the date that is 15 calendar days plus three (3) business days before the last day of the 90-day restricted period and ends on the last day of the 90-day restricted period, the Company issues an earnings release or material news or a material event relating to the Company occurs, or (ii) prior to the expiration of the 90-day restricted period, the

Company announces that it will release earnings results during the 16-day period beginning on the last day of the 90-day restricted period, the restrictions set forth herein will continue to apply until the expiration of the date that is 15 calendar days plus three (3) business days after the date on which the earnings release is issued or the material news or event related to the Company occurs. The Company shall promptly notify the Underwriters of any earnings releases, news or events that may give rise to an extension of the initial restricted period.

Notwithstanding the foregoing, the undersigned may transfer the undersigned’s shares of Common Stock (i) as a bona fide gift or gifts, provided that the donee or donees agree to be bound in writing by the restrictions set forth herein, (ii) to any trust or family limited partnership for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust or general partner of the family limited partnership, as the case may be, agrees to be bound by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, (iii) pledged in a bona fide transaction outstanding as of the date hereof to a lender to the undersigned, as disclosed in writing to the Underwriters, (iv) pursuant to the exercise by the undersigned of stock options that have been granted by the Company prior to, and are outstanding as of, the date of the Underwriting Agreement, where the Common Stock received upon any such exercise is held by the undersigned, individually or as fiduciary, in accordance with the terms of this Lock-Up Agreement, or (v) with the prior written consent of the Underwriters.1 For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.

The undersigned now has and, except as contemplated by clauses (i) through (v) above, for the duration of the Lock-Up Agreement will have good and marketable title to the undersigned’s shares of Common Stock, free and clear of all liens, encumbrances, and claims whatsoever, except with respect to any liens, encumbrances and claims that were in existence on the date hereof. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s common stock, except in compliance with this Lock-Up Agreement. In furtherance of the foregoing, the Company and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Agreement.

The undersigned represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Agreement. The undersigned agrees that the provisions of this Lock-Up Agreement shall be binding also upon the successors, assigns, heirs and personal representatives of the undersigned.

The undersigned understands that, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Stock to be sold thereunder, the undersigned shall be released from all obligations under this Lock-up Agreement.

This Lock-up Agreement shall be governed by and construed in accordance with the laws of the State of New York.


Very truly yours,

Richard S. Cupp, the Chief Executive Officer of Center Financial Corporation, a California corporation (“Center”), and Douglas J. Goddard, the Interim Chief Financial Officer of Center, pursuant to Section 5(f) of the underwriting agreement, dated October , 2011 (the “Underwriting Agreement”), between Nara Bancorp, Inc. (“Nara”) and Keefe, Bruyette & Woods, Inc. and D.A. Davidson & Co., do hereby certify as follows:

1. The historical information relating to Center included, incorporated or deemed to be incorporated by reference into the Registration Statement, the General Disclosure Package or the Prospectus, as the case may be, (i) at the earlier of the time the Prospectus was first used and the date and time of the first contract of sale of the Securities and (ii) at the date hereof, did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

2. KPMG LLP, the accounting firm that certified certain financial statements of Center incorporated by reference into the Registration Statement, the General Disclosure Package and the Prospectus, is an independent registered public accounting firm as required by the 1933 Act and the 1933 Act Regulations and Grant Thornton LLP, the accounting firm that certified certain other financial statements of Center included in the Registration Statement and the Prospectus, was, during the period of its engagement as auditors for Center, an independent registered public accounting firm as required by the 1933 Act and the 1933 Act Regulations.

3. The financial statements of Center included, incorporated or deemed to be incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus, together with the related notes, present fairly the financial position of Center and its consolidated subsidiaries at the dates indicated and the statement of operations, stockholders’ equity and cash flows of Center and its consolidated subsidiaries for the periods specified. Such financial statements have been prepared in conformity with GAAP applied on a consistent basis throughout the periods involved. The portions of the selected financial data and the portions of the summary historical financial information, in each case, related to the Center financial statements, included, incorporated or deemed to be incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus present fairly the information shown therein and have been compiled on a basis consistent in all material respects with that of the audited financial statements of Center included, incorporated or deemed to be incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus and the books and records of Center.

4. Since the respective dates as of which information is included, incorporated or deemed incorporated by reference in the Registration Statement, the General Disclosure Package or the Prospectus, except as otherwise stated in the Registration Statement, the General Disclosure Package and the Prospectus, (A) there has been no “Material Adverse Effect” as to Center (as defined in the Merger Agreement) (a “Center Material Adverse Effect”), (B) there

have been no transactions entered into by Center or any of its subsidiaries, other than those in the ordinary course of business or permitted by the Merger Agreement, which are material with respect to Center and its subsidiaries considered as one enterprise, and (C) there has been no dividend or distribution of any kind declared, paid or made by Center on any class of its capital stock, except for dividends on Center’s Series A Fixed Rate Perpetual Preferred Stock.

5. The Merger Agreement has been duly authorized, executed and delivered by Center and constitutes a valid and binding agreement of Center and is enforceable against Center in accordance with its terms. Except as disclosed in the Disclosure Letter delivered by Center pursuant to the Merger Agreement (the “Center Disclosure Letter”), neither Center nor any of its subsidiaries is (a) in violation of its charter or by-laws or (b) in default in the performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or other agreement or instrument to which Center or any of its subsidiaries is a party or by which it or any of them may be bound, or to which any of the property or assets of Center or any subsidiary is subject (collectively, “Agreements and Instruments”) except in the case of clause (b) for such defaults that would not, individually or in the aggregate, result in a Center Material Adverse Effect; and the execution, delivery and performance of the Merger Agreement and the consummation of the transactions contemplated therein and compliance by Center with its obligations thereunder do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined below) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of Center or any subsidiary pursuant to, the Agreements and Instruments (except for such as have been obtained and for such conflicts, breaches or defaults or liens, charges or encumbrances that would not, individually or in the aggregate, result in a Center Material Adverse Effect), nor will such action result in any violation of the provisions of the charter or by-laws of Center or any subsidiary or any applicable law, statute, rule, regulation, judgment, order, writ or decree of any Government Entity having jurisdiction over Center or any subsidiary or any of their assets, properties or operations. As used herein, a “Repayment Event” means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by Center or any Subsidiary.

6. Except for the Memorandum of Understanding, effective as of December 9, 2009, between the Federal Reserve Bank of San Francisco and Center, (a) neither Center nor any of its subsidiaries is a party to or subject to any order, decree, agreement, memorandum of understanding or similar agreement with, or a commitment letter, supervisory letter or similar submission to, any governmental entity charged with the supervision or regulation of depository institutions or engaged in the insurance of deposits (including the DFI) or the supervision or regulation of it or any of its subsidiaries and (b) neither Center nor any of its subsidiaries has been advised by any such governmental entity that such governmental entity is contemplating issuing or requesting (or is considering the appropriateness of issuing or requesting) any order, decree, agreement, memorandum of understanding, commitment letter, supervisory letter or similar submission.

7. There is no action, suit, proceeding, inquiry or investigation before or brought by any court or governmental agency or body, domestic or foreign, now pending, or, to the knowledge of Center, threatened, against or affecting Center or any subsidiary, which would, individually or in the aggregate, result in a Center Material Adverse Effect, or which would materially and adversely affect the properties or assets thereof or the consummation of the transactions contemplated in the Underwriting Agreement or the Merger Agreement or the performance by Center of its obligations under the Merger Agreement.

Capitalized terms used and not defined herein shall have the meanings ascribed to such terms in the Underwriting Agreement.

In Witness Whereof, the undersigned have executed this certificate as of the date first written above.
