NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS

SEPTEMBER 30, 2006

(UNAUDITED)

1. BASIS OF PRESENTATION

The interim consolidated financial statements include the accounts of Prosperity Bancshares, Inc. ^®(the “Company”) and its wholly-owned subsidiaries, Prosperity Bank ^®(the “Bank”) and Prosperity Holdings of Delaware, L.L.C. All significant inter-company transactions and balances have been eliminated.

The accompanying unaudited interim consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, the statements reflect all adjustments necessary for a fair presentation of the financial position, results of operations and cash flows of the Company on a consolidated basis, and all such adjustments are of a normal recurring nature. These financial statements and the notes thereto should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2005. Operating results for the nine month period ended September 30, 2006 are not necessarily indicative of the results that may be expected for the year ending December 31, 2006.

2. EARNINGS PER SHARE

The following table illustrates the computation of basic and diluted earnings per share:


	Three Months Ended September 30,				Nine Months Ended September 30,
	2006		2005		2006		2005
	(In thousands, except per share amounts)
Net income available to common shareholders	$	16,364	$	12,471	$	45,123	$	35,233

Weighted average common shares outstanding		32,771		27,546		31,053		26,389
Potential dilutive common shares		411		353		399		312

Weighted average common shares and equivalents outstanding		33,182		27,899		31,452		26,701

Basic earnings per common share	$	0.50	$	0.45	$	1.45	$	1.34

Diluted earnings per common share	$	0.49	$	0.45	$	1.43	$	1.32

Basic earnings per share is computed by dividing net income by the weighted-average number of shares outstanding during the applicable period. Diluted earnings per share is computed using the weighted-average number of shares determined for the basic computation plus the dilutive effect of stock options and non-vested stock granted using the treasury stock method. There were no stock options exercisable at September 30, 2006 and 2005 that would have had an anti-dilutive effect on the above computation.

3. NEW ACCOUNTING STANDARDS

SFAS No. 157, “Fair Value Measurement”. In 2006, the Financial Accounting Standards Board (“FASB”) issued FASB Statement No. 157 (“SFAS 157”). SFAS 157 provides a single definition of fair value, together with a framework for measuring it, and requires additional disclosure about the use of fair value to measure assets and liabilities. SFAS 157 also emphasizes that fair value is a market-based measurement, not an entity-specific measurement, and sets out a fair value hierarchy with the highest priority being quoted prices in active markets. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007. The Company is currently evaluating the impact of the adoption of this accounting standard on its financial statements.

NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS

SEPTEMBER 30, 2006

(UNAUDITED)

In June 2006, the FASB issued FASB Interpretation No. 48 (“FIN 48”) Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109. FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements in accordance with FASB Statement No. 109 (“FAS 109”), Accounting for Income Taxes. FIN 48 clarifies the application of FAS 109 by defining a criterion that an individual tax position must meet for any part of the benefit of that position to be recognized in an enterprise’s financial statements. Additionally, FIN 48 provides guidance on measurement, derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. FIN 48 is effective for fiscal years beginning after December 15, 2006. The Company is currently evaluating the impact of the adoption of this accounting standard on its financial statements.

SFAS No. 123(R), “Share-Based Payment (Revised 2004).” SFAS 123(R) establishes standards for the accounting for transactions in which an entity (i) exchanges its equity instruments for goods or services, or (ii) incurs liabilities in exchange for goods or services that are based on the fair value of the entity’s equity instruments or that may be settled by the issuance of the equity instruments. SFAS 123(R) eliminates the ability to account for stock-based compensation using Accounting Pronouncements Board (“APB”) 25 and requires that such transactions be recognized as compensation cost in the income statement based on their fair values on the date of the grant. SFAS 123(R) applies to new awards, modified awards and to awards cancelled after January 1, 2006. SFAS 123(R) was effective on January 1, 2006 and its adoption did not have a material impact on the Company’s financial statements. The Company had previously adopted SFAS No. 123 on January 1, 2003. The Company recorded $606,000 in stock based compensation expense for the nine months ended September 30, 2006. There was no income tax benefit recorded for the stock-based compensation expense.

4. GOODWILL AND CORE DEPOSIT INTANGIBLES

Changes in the carrying amount of the Company’s goodwill and core deposit intangibles (CDI) for nine months ended September 30, 2006 were as follows:


	Goodwill		Core Deposit Intangibles
	(In thousands)
Balance as of December 31, 2005	$	261,964	$	22,461
Amortization		—		(3,616	)
Acquisition of SNB Bancshares, Inc.		161,655		5,734
Acquisition of Grapeland Bancshares, Inc.		667		(294	)
Acquisition of First Capital Bankers, Inc.		371		—
Acquisitions prior to December 31, 2004 (deferred taxes)		416		—

Balance as of September 30, 2006	$	425,073	$	24,285

Gross core deposit intangibles outstanding were $34.6 million at September 30, 2006 and $29.2 million at December 31, 2005. Purchase accounting adjustments to prior year acquisitions were made to adjust deferred tax asset and liability balances. Goodwill is recorded on the acquisition date of each entity. The Company may record subsequent adjustments to goodwill for amounts undeterminable at acquisition date, such as deferred taxes, and therefore the goodwill amounts reflected in the table above may change accordingly. The Company initially records the total premium paid on acquisitions as goodwill. After a third party valuation, core deposit intangibles are identified and reclassified from goodwill to core deposit intangibles on the balance sheet. This reclassification had no effect on total assets, liabilities, shareholders’ equity, net income or cash flows. Management performs an annual evaluation of whether any impairment of the goodwill and other intangibles has occurred. If any such impairment is determined, a write down is recorded. As of September 30, 2006, there were no impairments recorded on goodwill.

5. STOCK BASED COMPENSATION

At September 30, 2006, the Company had two stock-based employee compensation plans and four stock option plans assumed in connection with acquisitions under which no additional options will be granted. Prior to 2003, the Company accounted for those plans under the recognition and measurement provisions of APB Opinion No. 25, Accounting for Stock Issued to Employees, and related Interpretations. Effective January 1, 2003, the Company adopted the fair value recognition provisions of SFAS No. 123, Accounting for Stack-Based Compensation, as provided by SFAS No. 148 for stock-based employee compensation. The Company adopted SFAS 123(R) on January 1, 2006. The Company recognized $606,000 and $481,000 in stock-based compensation expense for the nine months ended September 30, 2006 and 2005 and $223,000 and $177,000 in stock-based compensation expense for the three months ended September 30, 2006 and 2005, respectively. There was no income tax benefit recorded for the stock-based compensation expense for the same periods.

Stock options are issued at the current market price on the date of the grant, subject to a pre-determined vesting period with a contractual term of 10 years. Options assumed in connection with acquisitions have contractual terms as established in the original option grant agreements entered into prior to acquisition. The fair value of stock options granted is estimated at the date of grant using the Black-Scholes option-pricing model. Stock-based compensation expense is recognized ratably over the requisite service period for all awards.

The fair value of options was estimated using an option-pricing model with the following weighted average assumptions:


	September 30,
	2006		2005
Expected life in years	4.64		4.63
Risk free interest rate	4.18	%	4.19	%
Volatility	21.29	%	21.40	%
Dividend yield	1.27	%	1.30	%

A summary of changes in outstanding vested and unvested options during the nine months ended September 30, 2006 is set forth below:


	Number of Options		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term	Aggregate Intrinsic Value
	(In thousands)					(In thousands)
Options outstanding, beginning of period	1,169		$	21.58
Options granted (1)	507			16.47

Under the terms of the merger agreement, SNB was merged into the Company and subsequently, SNB’s wholly owned subsidiary, Southern National Bank of Texas, was merged into Prosperity Bank^® (“Prosperity Bank^®” or the “Bank”) . The Company issued 4.448 million shares of its common stock and $93.8 million in cash for all of the issued and outstanding capital stock of SNB. In addition, options to acquire 762,950 shares of SNB common stock were converted into options to acquire 467,578 shares of Company common stock.

PENDING ACQUISITION

OVERVIEW

The Company was formed in 1983 as a vehicle to acquire the former Allied First Bank in Edna, Texas which was chartered in 1949 as The First National Bank of Edna. The Company is a registered financial holding company that derives substantially all of its revenues and income from the operation of its bank subsidiary, Prosperity Bank^®. The Bank provides a wide array of financial products and services to small and medium-sized businesses and consumers. The Bank operates eighty-eight (88) full-service banking locations; with thirty-eight (38) in the Greater Houston Consolidated Metropolitan Statistical Area (“CMSA”), seventeen (17) in fifteen contiguous counties situated south and southwest of Houston and extending into South Texas, five (5) in the Austin, Texas area, fifteen (15) in the Corpus Christi, Texas area, two (2) in East Texas and eleven (11) in the Dallas/Fort Worth, Texas area. The Greater Houston CMSA includes Austin, Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, San Jacinto and Waller counties. The Company’s headquarters are located at Prosperity Bank Plaza, 4295 San Felipe in Houston, Texas and its telephone number is (713) 693-9300. The Company’s website address is www.prosperitybanktx.com. Information contained on the Company’s website is not incorporated by reference into this quarterly report on Form 10-Q and is not part of this or any other report.

The Company generates the majority of its revenues from interest income on loans, service charges on customer accounts and income from investment in securities. The revenues are partially offset by interest expense paid on deposits and other borrowings and non-interest expenses such as administrative and occupancy expenses. Net interest income is the difference between interest income on earning assets such as loans and securities and interest expense on liabilities such as deposits and borrowings which are used to fund those assets. The level of interest rates and the volume and mix of earning assets and interest-bearing liabilities impact net interest income and margin. The Company has recognized increased net interest income primarily due to an increase in the volume of interest-earning assets.

Three principal components of the Company’s growth strategy are internal growth, stringent cost control practices and strategic merger transactions. The Company focuses on continual internal growth. Each banking center is operated as a separate profit center, maintaining separate data with respect to its net interest income, efficiency ratio, deposit growth, loan growth and overall profitability. Banking center presidents and managers are accountable for performance in these areas and compensated accordingly. The Company also focuses on maintaining stringent cost control practices and policies. The Company has invested significantly in the infrastructure required to centralize many of its critical operations, such as data processing and loan application processing. Management believes that this centralized infrastructure can accommodate substantial additional growth while enabling the Company to minimize operational costs through certain economies of scale. The Company also intends to continue to seek expansion opportunities. On March 1, 2005, the Company acquired First Capital Bankers, Inc. (the “First Capital acquisition”) which added an additional twenty seven (27) banking centers, and on December 1, 2005, the Company acquired Grapeland Bancshares, Inc. (the “Grapeland acquisition”) which added two banking centers. On April 1, 2006, the Company acquired SNB which added five banking centers.

Total assets were $4.46 billion at September 30, 2006 compared with $3.59 billion at December 31, 2005, an increase of $869.7 million or 24.3%. Total loans were $2.21 billion at September 30, 2006 compared with $1.54 billion at December 31, 2005, an increase of $672.3 million or 43.6%. Total deposits were $3.59 billion at September 30, 2006 compared with $2.92 billion at December 31, 2005, an increase of $672.8 million, or 23.0%. Shareholders’ equity increased $185.4 million or 39.9%, to $650.2 million at September 30, 2006 compared with $464.7 million at December 31, 2005. These increases were primarily the result of the SNB acquisition in April 2006.

CRITICAL ACCOUNTING POLICIES

The Company’s accounting policies are integral to understanding the financial results reported. Accounting policies are described in detail in Note 1 to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2005. The Company believes that of its significant accounting policies, the following may involve a higher degree of judgment and complexity:

Allowance for Credit Losses—The allowance for credit losses is a reserve established through charges to earnings in the form of a provision for credit losses. Management has established an allowance for credit losses which it believes is adequate for estimated losses in the Company’s loan portfolio. Based on an evaluation of the loan portfolio, management presents a monthly review of the allowance for credit losses to the Bank’s Board of Directors, indicating any change in the allowance since the last review and any recommendations as to adjustments in the allowance. In making its evaluation, management considers factors such as historical loan loss experience, industry diversification of the Company’s commercial loan portfolio, the amount of nonperforming assets and related collateral, the volume, growth and composition of the Company’s loan portfolio, current economic changes that may affect the borrower’s ability to pay and the value of collateral, the evaluation of the Company’s loan portfolio through its internal loan review process and other relevant factors. Portions of the allowance may be allocated for specific credits; however, the entire allowance is available for any credit that, in management’s judgment, should be charged off. Charge-offs occur when loans are deemed to be uncollectible. The allowance for credit losses includes allowance allocations calculated in accordance with Statement of Financial Accounting Standards (SFAS) No. 114, “Accounting by Creditors for Impairment of a Loan,” as amended by SFAS 118, and allowance allocations determined in accordance with SFAS No. 5, “Accounting for Contingencies.”

Goodwill—Goodwill and intangible assets that have indefinite useful lives are subject to an annual impairment test at least annually and more frequently if circumstances indicate their value may not be recoverable. Goodwill is tested for impairment using a two-step process that begins with an estimation of the fair value of each of the Company’s reporting units compared with its carrying value. If the carrying amount exceeds the fair value of a reporting unit, a second step test is completed comparing the implied fair value of the reporting unit’s goodwill to its carrying value to measure the amount of impairment. Intangible assets that are not amortized will be tested for impairment at least annually by comparing the fair values of those assets to their carrying values. Other identifiable intangible assets that are subject to amortization are amortized on an accelerated basis over

the years expected to be benefited, which the Company believes is eight years. These amortizable intangible assets are reviewed for impairment if circumstances indicate their value may not be recoverable based on a comparison of fair value to carrying value. Based on the Company’s annual goodwill impairment test as of September 30, 2006, management does not believe any of its goodwill is impaired as of September 30, 2006. While the Company believes no impairment existed at September 30, 2006 under accounting standards applicable at that date, different conditions or assumptions, or changes in cash flows or profitability, if significantly negative or unfavorable, could have a material adverse effect on the outcome of the Company’s impairment evaluation and financial condition or future results of operations.

Stock-Based Compensation—The Company adopted the provisions of SFAS No. 123R “Share-Based Payment (Revised 2004),” on January 1, 2006 and its adoption did not have a material impact on the Company’s financial statements. The Company had previously adopted SFAS No. 123 on January 1, 2003. Among other things, SFAS No. 123R eliminates the ability to account for stock-based compensation using the intrinsic value based method of accounting and requires that such transactions be recognized as compensation expense in the income statement based on their fair values on the date of the grant. SFAS No. 123R requires that management make assumptions including stock price volatility and employee turnover that are utilized to measure compensation expense. The fair value of stock options granted is estimated at the date of grant using the Black-Scholes option-pricing model. This model requires the input of highly subjective assumptions.

Valuation of Securities – The Company’s available for sale securities portfolio is reported at fair value. When the fair value of a security is below its amortized cost, and depending on the length of time the condition exists and the extent the fair market value is below amortized cost, additional analysis is performed to determine whether an impairment exists. Available for sale and held to maturity securities are analyzed quarterly for possible other-than-temporary impairment. The analysis considers the financial condition and near-term prospects of the issuer, as well as the value of any security we may have in the investment. Often, the information available to conduct these assessments is limited and rapidly changing, making estimates of fair value subject to judgment. If actual information or conditions are different than estimated, the extent of the impairment of the security may be different than previously estimated, which could have a material effect on the Company’s results of operations and financial condition.

RESULTS OF OPERATIONS

Net income available to common shareholders was $16.4 million ($0.49 per common share on a diluted basis) for the quarter ended September 30, 2006 compared with $12.5 million ($0.45 per common share on a diluted basis) for the quarter ended September 30, 2005, an increase in net income of $3.9 million, or 31.2%. The Company posted returns on average common equity of 10.17% and 11.28%, returns on average assets of 1.46% and 1.43% and efficiency ratios of 44.31% and 48.84% for the quarters ended September 30, 2006 and 2005, respectively. The efficiency ratio is calculated by dividing total non-interest expense (excluding credit loss provisions) by net interest income plus non-interest income (excluding net gains and losses on the sale of securities and on the sale assets). Additionally, taxes are not part of this calculation.

For the nine months ended September 30, 2006, net income available to common shareholders was $45.1 million ($1.43 per common share on a diluted basis) compared with $35.2 million ($1.32 per common share on a diluted basis) for the same period in 2005, an increase in net income of $9.9 million or 28.1%. The Company posted returns on average common equity of 10.32% and 11.73%, returns on average assets of 1.43% and 1.42% and efficiency ratios of 46.08% and 49.54% for the nine months ended September 30, 2006 and 2005, respectively.

Net Interest Income

Net interest income on a tax equivalent basis was $36.5 million for the quarter ended September 30, 2006 compared with $29.3 million for the quarter ended September 30, 2005, an increase of $7.2 million, or 24.6%. Net interest income increased as a result of an increase in average interest-earning assets to $3.83 billion for the quarter ended September 30, 2006 compared with $3.05 billion for the quarter ended September 30, 2005, an increase of $783.1 million, or 25.7%. The increase in average interest-earning assets is primarily attributable to increases in average loans and securities in the quarter ended September 30, 2006 compared to the quarter ended September 30, 2005 resulting from the SNB acquisition.

The net interest margin on a tax equivalent basis decreased to 3.77% for the quarter ended September 30, 2006 compared with 3.81% for the quarter ended September 30, 2005. The average rate paid on interest-bearing liabilities increased 119 basis points from 2.28% for the quarter ended September 30, 2005 compared with 3.47% for the quarter ended September 30, 2006, while the average yield on earning assets increased 88 basis points from 5.55% for the quarter ended September 30, 2005 compared with 6.43% for the quarter ended September 30, 2006. Average interest-bearing liabilities increased $593.9 million and average interest-earning assets increased $783.1 million for the same periods.

Net interest income on a tax equivalent basis increased $20.2 million, or 24.3%, to $103.1 million for the nine months ended September 30, 2006 compared with $82.9 million for the same period in 2005. This increase is mainly attributable to higher average interest-earning assets resulting from an increase in average loans and securities. The net interest margin on a tax equivalent basis for the nine months ended September 30, 2006 remained flat at 3.81% when compared to the same period in 2005. The average rate paid on interest-bearing liabilities increased 109 basis points from 2.09% for the nine months ended September 30, 2005 compared with 3.18% for the same period in 2006 and the average yield on earning assets increased 81 basis points from 5.42% for the nine months ended September 30, 2005 compared with 6.23% for the nine months ended September 30, 2006.

The Company’s net interest income is affected by changes in the amount and mix of interest-earning assets and interest-bearing liabilities, referred to as a “volume change.” It is also affected by changes in yields earned on interest-earning assets and rates paid on interest-bearing deposits and other borrowed funds, referred to as a “rate change.”

The following tables set forth, for each category of interest-earning assets and interest-bearing liabilities, the average amounts outstanding, the interest earned or paid on such amounts, and the average rate earned or paid for the quarters ended September 30, 2006 and 2005 and the nine months ended September 30, 2006 and 2005. The tables also set forth the average rate paid on total interest-bearing liabilities, and the net interest margin on average total interest-earning assets for the same periods. Except as indicated in the footnotes, no tax-equivalent adjustments were made and all average balances are daily average balances. Any nonaccruing loans have been included in the table as loans carrying a zero yield.

(1)	Yield is based on amortized cost and does not include any component of unrealized gains or losses.

(2)	The net interest margin is equal to net interest income divided by average interest-earning assets.

(3)	In order to make pretax income and resultant yields on tax-exempt investments and loans comparable to those on taxable investments and loans, a tax-equivalent adjustment has been computed using a federal income tax rate of 35%.

(4)	Annualized. Average yield and average rate are calculated on an actual/365 day basis except for the average yield on securities which is calculated on a 30/360 day basis.

The following tables present the dollar amount of changes in interest income and interest expense for the major components of interest-earning assets and interest-bearing liabilities and distinguish between the increase (decrease) related to outstanding balances and the volatility of interest rates. For purposes of these tables, changes attributable to both rate and volume which cannot be segregated have been allocated to rate.

Provision for Credit Losses

Management actively monitors the Company’s asset quality and provides specific loss provisions when necessary. Provisions for credit losses are charged to income to bring the total allowance for credit losses to a level deemed appropriate by management of the Company based on such factors as historical credit loss experience, industry diversification of the commercial loan portfolio, the amount of nonperforming loans and related collateral, the volume growth and composition of the loan portfolio, current economic conditions that may affect the borrower’s ability to pay and the value of collateral, the evaluation of the loan portfolio through the internal loan review function and other relevant factors.

Loans are charged-off against the allowance for credit losses when appropriate. Although management believes it uses the best information available to make determinations with respect to the provision for credit losses, future adjustments may be necessary if economic conditions differ from the assumptions used in making the initial determinations.

The Company made a $120,000 provision for credit losses for the quarter ended September 30, 2006 and 2005. The Company made a $360,000 provision for credit losses for the nine months ended September 30, 2006 and 2005. The ratio of the allowance for credit losses to end of period nonperforming loans was 2,038.3% for the nine months ended September 30, 2006 compared with 1,505.1% for the year ended December 31, 2005. The ratio of allowance for credit losses to total loans was 1.09% at September 30, 2006 compared with 1.12% at December 31, 2005. For the quarter ended September 30, 2006, net charge-offs were $307,000 compared with net charge-offs of $89,000 for the quarter ended September 30, 2005. Net charge-offs were $524,000 for the nine months ended September 30, 2006 compared with $98,000 for the nine months ended September 30, 2005.

Noninterest Income

The Company’s primary sources of noninterest income are service charges on deposit accounts, which include insufficient funds charges and other banking-related service fees. Noninterest income does not include loan origination fees which are recognized over the life of the related loan as an adjustment to yield using the interest method. Banking-related service fees include check cashing fees, official check fees, safe deposit box rent and currency handling fees. Noninterest income totaled $8.9 million for the three months ended September 30, 2006 compared with $8.1 million for the same period in 2005, an increase of $826,000, or 10.2%. Noninterest income increased $3.2 million, or 14.4%, to $25.7 million for the nine months ended September 30, 2006 compared with $22.5 million for the same period in 2005. The increases during both periods were primarily due to an increase in insufficient funds charges and customer service charges which mainly resulted from an increase in the number of accounts due to the SNB acquisition and the acquisition of Grapeland Bancshares, Inc. in December 2005. At September 30, 2006, the two acquisitions added approximately 14,800 deposit accounts and over 4,400 debit cards.

The following table presents, for the periods indicated, the major categories of noninterest income:

Noninterest Expense

Noninterest expense totaled $19.8 million for the quarter ended September 30, 2006 compared with $18.1 million for the quarter ended September 30, 2005, an increase of $1.8 million, or 9.7%. This increase occurred primarily in salaries and employee benefits, core deposit intangibles amortization and occupancy and equipment expense. Noninterest expense totaled $58.5 million for the nine months ended September 30, 2006 compared with $51.7 million for the nine months ended September 30, 2005, an increase of $6.8 million, or 13.1%. The increases during both periods were primarily due to the SNB and Grapeland acquisitions. The following table presents, for the periods indicated, the major categories of noninterest expense:


	Three Months Ended September 30,				Nine Months Ended September 30,
	2006		2005		2006		2005

(1)	Includes stock based compensation expense of $223 and $177 for the three months ended September 30, 2006 and 2005, respectively, and $606 and $481 for the nine months ended September 30, 2006 and 2005, respectively.

Salaries and employee benefit expenses were $10.3 million for the quarter ended September 30, 2006 compared with $9.7 million for the quarter ended September 30, 2005, an increase of $615,000, or 6.4%. For the nine months ended September 30, 2006, salaries and employee benefit expenses were $31.2 million, an increase of $3.5 million or 12.6% compared with $27.7 million for the nine months ended September 30, 2005. The increases during both periods were principally due to additional staff associated with the SNB acquisition and routine annual salary increases. The number of full-time equivalent (FTE) associates employed by the Company increased from 857 at September 30, 2005 to 914 at September 30, 2006.

Non-staff expenses increased $1.1 million, or 13.6%, to $9.6 million for the quarter ended September 30, 2006 compared with $8.4 million during the same period in 2005. Non-staff expenses increased $3.3 million, or 13.6%, to $27.3 million for the nine months ended September 30, 2006 compared to $24.0 million during the same period in 2005. The increases during both periods were principally due to additional expenses associated with SNB and Grapeland acquisitions, increases in core deposit intangibles amortization related to the 2005 and 2006 acquisitions and increases in occupancy and equipment expense due to the additional banking centers acquired in 2005 and 2006.

Income Taxes

Income tax expense increased $2.2 million or 35.0% to $8.6 million for the quarter ended September 30, 2006 compared with $6.4 million for the same period in 2005. For the nine months ended September 30, 2006, income tax expense totaled $23.5 million, an increase of $6.4 million or 37.8% compared with $17.1 million for the same period in 2005. Both increases were primarily attributable to higher pretax net earnings for the quarter and nine months ended September 30, 2006 when compared to the same respective periods in 2005. The effective tax rates for the three months ended September 30, 2006 and 2005 and the nine months ended September 30, 2006 and 2005 were 34.4%, 33.7%, 34.3% and 32.6%, respectively.

Allowance for Credit Losses

Management actively monitors the Company’s asset quality and provides specific loss allowances when necessary. Loans are charged-off against the allowance for credit losses when appropriate. Although management believes it uses the best information available to make determinations with respect to the allowance for credit losses, future adjustments may be necessary if economic conditions differ from the assumptions used in making the initial determinations. As of September 30, 2006, the allowance for credit losses amounted to $24.1 million, or 1.09% of total loans, compared with $17.2 million, or 1.12% of total loans at December 31, 2005.

Other Borrowings

The Company utilizes borrowings to supplement deposits to fund its lending and investment activities. Borrowings consist of funds from the Federal Home Loan Bank (“FHLB”) and correspondent banks and can be short-term advances or long-term notes payable. At September 30, 2006, the Company had $31.5 million in FHLB borrowings of which all consisted of long-term FHLB notes payable compared with $55.4 million in FHLB borrowings at December 31, 2005, which consisted of $38.4 million in long-term FHLB notes payable and $17.0 million in FHLB advances. The maturity dates on the FHLB notes payable range from the years 2006 to 2028 and have interest rates ranging from 2.79% to 6.48%. The highest outstanding balance of FHLB advances during the nine months ended September 30, 2006 was $116.0 million compared with $39.0 million during the year ended December 31, 2005. The Company had no federal funds purchased at September 30, 2006 or December 31, 2005.

Junior Subordinated Debentures

At September 30, 2006 and December 31, 2005, the Company had outstanding $100.5 million and $75.8 million, respectively, in junior subordinated debentures issued to the Company’s subsidiary trusts. The increase of $24.7 million was due to the Company’s assumption of $30.9 million in junior subordinated debentures issued by SNB to its three subsidiary trusts, partially offset by the redemption of $6.2 million junior subordinated debentures held by Paradigm Capital Trust II on February 28, 2006.

A summary of pertinent information related to the Company’s eight issues of junior subordinated debentures outstanding at September 30, 2006 is set forth in the table below:

Liquidity

Liquidity involves the Company’s ability to raise funds to support asset growth or reduce assets to meet deposit withdrawals and other payment obligations, to maintain reserve requirements and otherwise to operate the Company on an ongoing basis. The Company’s liquidity needs have primarily been met by growth in core deposits and the issuance of junior subordinated debentures. Although access to purchased funds from correspondent banks is available and has been utilized on occasion to take advantage of investment opportunities, the Company does not generally rely on these external funding sources. The cash and federal funds sold position, supplemented by amortizing investment and loan portfolios, have generally created an adequate liquidity position.

Asset liquidity is provided by cash and assets which are readily marketable or which will mature in the near future. As of September 30, 2006, the Company had cash and cash equivalents of $116.2 million compared with $97.4 million at December 31, 2005.

Contractual Obligations

The following table summarizes the Company’s contractual obligations and other commitments to make future payments as of September 30, 2006 (other than deposit obligations). The Company’s future cash payments associated with its contractual obligations pursuant to its junior subordinated debentures, FHLB notes payable and operating leases as of September 30, 2006 are summarized below. Payments for FHLB notes payable do not include interest of $7.0 million that will be paid over the future periods presented. Payments related to leases are based on actual payments specified in underlying contracts.

Off-Balance Sheet Items

In the normal course of business, the Company enters into various transactions, which, in accordance with accounting principles generally accepted in the United States, are not included in its consolidated balance sheets. The Company enters into these transactions to meet the financing needs of its customers. These transactions include commitments to extend credit and standby letters of credit, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in the consolidated balance sheets.

The Company’s commitments associated with outstanding standby letters of credit and commitments to extend credit as of September 30, 2006 are summarized below. Since commitments associated with letters of credit and commitments to extend credit may expire unused, the amounts shown do not necessarily reflect the actual future cash funding requirements.


	Remaining Fiscal 2006		Fiscal 2007-2008		Fiscal 2009-2010		Thereafter		Total
	(Dollars in thousands)

Capital Resources

Total shareholders’ equity was $650.2 million at September 30, 2006 compared with $464.7 million at December 31, 2005, an increase of $185.4 million, or 39.9%. The increase was due primarily to net earnings of $45.1 million, common stock issued in connection with the SNB acquisition of $141.4 million and common stock issued in connection with the exercise of stock options and restricted stock of $7.8 million, partially offset by dividends paid of $9.3 million for the nine months ended September 30, 2006.

Both the Board of Governors of the Federal Reserve System with respect to the Company, and the Federal Deposit Insurance Corporation (“FDIC”) with respect to the Bank, have established certain minimum risk-based capital standards that apply to bank holding companies and federally insured banks. The following table sets forth the Company’s total risk-based capital, Tier I risk-based capital, and Tier I to average assets (leverage) ratios as of September 30, 2006:


Consolidated Risk Based Capital Ratios:
Total capital (to risk weighted assets)	14.16	%
Tier I capital (to risk weighted assets)	13.11	%
Tier I capital (to average assets)	7.44	%

As of September 30, 2006, the Bank’s risk-based capital ratios were above the levels required for the Bank to be designated as “well capitalized” by the FDIC. The following table sets forth the Bank’s total risk-based capital, Tier I risk-based capital, and Tier I to average assets (leverage) capital ratios as of September 30, 2006:

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company manages market risk, which for the Company is primarily interest rate risk, through its Asset Liability Committee which is composed of senior officers of the Company, in accordance with policies approved by the Company’s Board of Directors.

The Company uses simulation analysis to examine the potential effects of market changes on net interest income and market value. The Company considers macroeconomic variables, Company strategy, liquidity and other factors as it quantifies market risk. See the Company’s Annual Report on Form 10-K, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations-Interest Rate Sensitivity and Liquidity” which was filed on March 15, 2006 for further discussion.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures. As of the end of the period covered by this report, the Company carried out an evaluation, under the supervision and with the participation of its management, including its Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of its disclosure controls and procedures. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management was required to apply judgment in evaluating its controls and procedures. Based on this evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)) are effective.

Changes in internal control over financial reporting.
