This Stock Purchase Agreement is made as of August 6, 2008, by and between Center Bank, a California banking corporation (“Center Bank”); Center Financial Corporation, a California corporation which owns 100% of the issued and outstanding shares of Center Bank (“CFC”); and Korea Export Insurance Corporation, a Korean corporation established by the Government of Korea (“KEIC”), with reference to the following:

RECITALS

WHEREAS, Center Bank and KEIC have entered into a Settlement Agreement of even date herewith (the “Settlement Agreement”), pursuant to which, among other things, Center Bank has agreed to deliver to KEIC shares of the authorized but unissued common stock of CFC, as set forth herein;

WHEREAS, the parties hereto desire to provide for the issuance and sale of such shares by CFC to KEIC in accordance with the terms hereof;

NOW, THEREFORE, the parties agree as follows:

1. On August 21, 2008, at 10:00 A.M. Pacific Time, or on such other date and time as the parties hereto shall mutually agree (the “Closing Date”), for good and valuable consideration, the receipt of which is hereby acknowledged, CFC shall issue and sell to KEIC, 415,369 shares of its authorized but unissued common stock (the “Settlement Shares”). The closing of the issuance and sale of the Settlement Shares (the “Closing”) will take place at the offices of Center Bank at 3435 Wilshire Boulevard, Suite 700, Los Angeles, California 90010. At the Closing CFC will deliver to KEIC a certificate or certificates representing all of the Settlement Shares registered in the name “Korea Export Insurance Corporation.”

2. KEIC acknowledges that the Settlement Shares are not being and will not be registered under the Securities Act of 1933, as amended (the “Securities Act”), or under the securities laws of any state or other jurisdiction; that the Settlement Shares are being offered and will be sold in reliance on exemptions from the registration requirements thereof, which reliance is predicated in part on the acknowledgements, agreements and representations of KEIC in this Agreement; and that CFC does not contemplate filing and is not legally required to effect any such registration. KEIC further acknowledges that the Settlement Shares must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available; and KEIC represents that it is familiar with Rule 144 promulgated under the Securities Act (“Rule 144”) and understands the resale limitations imposed thereby and under the Securities Act. CFC covenants and agrees that upon receipt of notice of a sale of the Settlement Shares to be made by KEIC in compliance with Rule 144, and receipt of all documentation which CFC’s counsel deems reasonably necessary to evidence compliance with Rule 144, it will promptly provide, or cause to be provided, an opinion of counsel to its transfer agent, with respect to such proposed sale.

3. KEIC acknowledges that it heretofore has received, or CFC or Center Bank has given KEIC access to, or advised KEIC how to access, all such information concerning CFC or Center Bank as KEIC deems necessary or appropriate to enable it to evaluate the business and financial merits and risks inherent in an investment in the Settlement Shares, including, but not limited to, the documents set forth in Schedule A annexed hereto. KEIC represents that it has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of an investment in the Settlement Shares, and that it is able to bear the risks of such investment. KEIC acknowledges that investment in the Settlement Shares involves substantial risks. KEIC represents that it is able to hold the Settlement Shares for an indefinite period of time; that it has adequate means, other than the Settlement Shares, of providing for its current and foreseeable needs; that it has no foreseeable need to sell or otherwise dispose of the Settlement Shares; and that it has sufficient net worth to sustain a loss of its entire investment in the Settlement Shares in the event such loss should occur.

4. KEIC represents that it is entering into this Agreement and is acquiring the Settlement Shares solely for its account; that the Shares are being acquired for investment and not with a view to, or for sale in connection with, any distribution thereof; and that it has no present intention of selling or distributing any of the Settlement Shares. KEIC agrees that it will not sell, distribute, transfer, pledge, hypothecate or otherwise dispose of any of the Settlement Shares in such a manner as will violate the Securities Act or any applicable rules or regulations thereunder or any other federal securities laws, any federal banking laws or the securities or banking laws of any state or other jurisdiction.

(vi) With respect to any proposed offer and sale of 50,000 or more shares of the common stock of CFC in any offer and sale other than a registered public offering or a sale pursuant to Rule 144 (a “Block Sale”), KEIC will give CFC prior written notice of such proposed Block Sale, which notice shall include the proposed sale date, the name of the buyer(s), the number of shares of common stock of CFC proposed to be sold by KEIC, the purchase price of such shares and any other material terms with respect to the proposed Block Sale.

3

CFC; provided, however, that if KEIC in good faith determines that voting the KEIC Shares in accordance with the recommendation of the CFC Board of Directors would endanger or impair any significant proprietary interest of KEIC, then KEIC may notify CFC of its determination not to vote the KEIC shares in accordance with the CFC Board recommendation (“Impairment Determination”). Such notice of Impairment Determination shall indicate the nature and amount of any proprietary interest of KEIC that may be impaired by the CFC Board recommendation and such notice must be given by KEIC to CFC within 10 days following KEIC’s receipt of the notice of meeting, or within 10 days from the date of receipt by KEIC of the request for written consent or other approval.

7. KEIC acknowledges and agrees that the certificate(s) representing the KEIC Shares may bear a restrictive legend in substantially the following form:

10. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction.
