Impact on Our Results of Operations - page 4 2. Your discussion of net income adjusted to exclude impairment losses in 2004 and prepayment penalties in 2003 is inappropriate.

Please supplementally address the following with regards to your impairment analysis: * How you considered the terms of the individual securities; * Which specific authoritative accounting literature you applied; and * How you determined that the additional declines in fair value as of September 30, 2004 did not constitute other than temporary impairments that would warrant taking a further impairment charge at that time. Recent Developments - page 29 4. Please revise your introductory paragraph to clarify that the information at September 30, 2004 and for the three and nine months ended September 30, 2004 and 2003 is derived from unaudited financial statements.

Provision for Loan Losses - page 72 9. Refer to prior comment 36. Your disclosure states that the recovery in 2003 related to one non-residential loan that had been charged-off by Success Bancshares prior to the acquisition. Please tell us if the $275,000 of non-residential real estate loans recovered in 2002 also related to one loan and if there is any relation to the loan recovered in 2003. 10. Please tell us how you determined these recoveries should be recorded as a credit to the allowance for loan losses rather than as a reduction of goodwill.

Please revise the language to clarify that the opinion is based upon the "more likely than not" analysis, rather than an assumption. Consolidated Financial Statements Note 1 - Summary of Significant Accounting Policies Allowance for Loan Losses - page F-9 12. Refer to prior comments 37 and 44.
