KAISER FEDERAL FINANCIAL GROUP, INC. TO COMMENCE STOCK

OFFERING

Covina, California, September 29, 2010 —K-Fed Bancorp (the “Company”) (NASDAQ: KFED), announced today that Kaiser Federal Financial Group, Inc., a Maryland corporation (“Kaiser Federal Financial Group”), the proposed holding company for Kaiser Federal Bank, and K-Fed Mutual Holding Company have received conditional regulatory approval from the Office of Thrift Supervision to commence Kaiser Federal Financial Group’s stock offering in connection with K-Fed Mutual Holding Company’s proposed second-step conversion. The Company also announced today that the registration statement relating to the sale of common stock of Kaiser Federal Financial Group has been declared effective by the Securities and Exchange Commission (the “SEC”).

Kaiser Federal Financial Group is offering for sale the 66.7% ownership interest in the Company currently owned by K-Fed Mutual Holding Company, which is equivalent to between $63.8 million and $86.3 million, or between 6,375,000 and 8,625,000 shares of common stock at $10.00 per share. Kaiser Federal Financial Group may increase the number of shares that it sells in the offering, without notice to persons who have subscribed for shares, by up to 15%, to $99.2 million or 9,918,750 shares at $10.00 per share, as a result of market demand or changes in the financial markets. The number of shares to be sold in the offering is based on an independent appraisal of the estimated pro forma market value of Kaiser Federal Financial Group as of August 6, 2010.

At the conclusion of the conversion and offering, the existing shares of common stock held by the public stockholders of the Company will be exchanged for between 0.7194 and 0.9733 shares of Kaiser Federal Financial Group, subject to a 15% increase to 1.1193 shares, based on the independent appraisal. The exchange ratio ranges could change as a result of regulatory review or due to updates to the independent appraisal, reflecting, among other things, changes in market conditions before or during the offering.

The completion of the conversion and offering is subject to, among other things, selling a minimum of 6,375,000 shares in the offering, the receipt of all necessary final regulatory approvals, the receipt of the approval of the members of K-Fed Mutual Holding Company (depositors of record of Kaiser Federal Bank) as of September 24, 2010, and the receipt of the approval of the stockholders of record of the Company as of September 24, 2010.

After the completion of the conversion and offering, Kaiser Federal Financial Group will be 100% owned by public stockholders, and the Company and K-Fed Mutual Holding Company will each cease to exist.

On or about October 8, 2010, offering materials will be mailed to Kaiser Federal Bank depositors eligible to purchase shares in the subscription offering, and proxy solicitation materials will be mailed to depositors and stockholders. Shares of common stock not sold in the subscription offering will be available in a community offering with a preference given first to the residents of Los Angeles, Orange, San Bernardino, Riverside and Santa Clara Counties, California and then to stockholders of the Company as of September 24, 2010. The subscription and community offerings are expected to expire at 2:00 p.m., Pacific Time, on October 29, 2010. Shares not sold in the subscription and community offerings are expected to be sold in a syndicated community offering. Keefe, Bruyette & Woods, Inc. is assisting Kaiser Federal Financial Group in selling its common stock in the subscription and community offerings on a best efforts basis. In the syndicated community offering, Keefe, Bruyette & Woods, Inc. will serve as sole book-running manager and Sterne, Agee & Leach, Inc. will serve as co-manager.

This press release contains certain forward-looking statements about the conversion and reorganization within the meaning of the Private Securities Litigation Reform Act of 1995.

They often include words such as “believe,” “expect,” “anticipate,” “estimate,” and “intend” or future or conditional verbs such as “will,” “would,” “should,” “could,” or “may.” Forward-looking statements, by their nature, are subject to risks and uncertainties. Certain factors that could cause actual results to differ materially from expected results include delays in consummation of the transactions contemplated by the Plan of Conversion and Reorganization; difficulties in selling the conversion stock or in selling the conversion stock within the expected time frame or offering range; increased competitive pressures; changes in the interest rate environment; demand for loans in the Company’s market area; adverse changes in general economic conditions, either nationally or in the Company’s market areas; adverse changes within the securities markets; legislative and regulatory changes that could adversely affect the business in which the Company and its subsidiaries are engaged; the future earnings and capital levels of Kaiser Federal Bank, which would affect the ability of Kaiser Federal Financial Group to pay dividends in accordance with its dividend policies; and other risks detailed from time to time in the Company’s SEC reports. Actual strategies and results in future periods may differ materially from those currently expected. These forward-looking statements represent the Company's judgment as of the date of this release. The Company disclaims, however, any intent or obligation to update these forward-looking statements.
