The incremental shares for the assumed exercise of the outstanding options were determined by
application of the treasury stock method. There were no stock options outstanding during the quarter ended June 30, 2009 or 2008 that would have had an anti-dilutive effect on the above computation.



|3. | NEW ACCOUNTING STANDARDS
|-- | ------------------------

Statements of Financial Accounting
Standards

In May 2009, the FASB issued SFAS No. 165, Subsequent Events, which establishes general standards of
accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. SFAS No. 165 is effective for interim or annual financial period ending after
June 15, 2009. The Company adopted SFAS No.165 as of June 30, 2009 and has included the appropriate disclosures.

In June 2009,
the FASB issued SFAS No. 166, Accounting for Transfers of Financial Assets, which is a revision to SFAS No. 140. It requires more information about transfers of financial assets, including securitization transactions and a
companys continuing exposure to the risks related to the transfer of financial assets. It eliminates the concept of a qualifying special-purpose entity and changes the requirements for derecognizing financial assets. SFAS
No. 166 is effective for first annual reporting period beginning after November 15, 2009. The Company is evaluating SFAS No. 166 but does not expect that it will have a significant impact on its consolidated financial statements.

In June 2009, the FASB issued SFAS No. 167, Amendments to FASB Interpretation
No. 46(R), which is a revision to FIN No. 46(R), Consolidation of Variable Interest Entities.It improves financial reporting by enterprises involved with variable interest entities and changes how a company determines when an
entity that is insufficiently capitalized or is not controlled through voting (or similar rights) should be consolidated. The determination of whether a company is required to consolidate an entity is based on, among other things, an entitys
purpose and design and a companys ability to direct the activities of the entity that most significantly impact the entitys economic performance. SFAS No. 167 is effective for first annual reporting period beginning after
November 15, 2009. The Company is evaluating SFAS No. 167 but does not expect that it will have a significant impact on its consolidated financial statements.

In June 2009, FASB issued SFAS No.168, FASB Accounting Standards Codification TM and the Hierarchy of Generally Accepted Accounting Principlesa replacement of FASB Statement No. 162,which states
that the FASB Accounting Standards CodificationTM (Codification) will become the source of authoritative U.S. generally accepted accounting principles (GAAP) recognized by the FASB to be applied by nongovernmental entities. On the effective date of
this Statement, the Codification will supersede all then-existing non-SEC accounting and reporting standards. All other nongrandfathered non-SEC accounting literature not included in the Codification will become nonauthoritative. SFAS No. 168
is effective for financial statements issued for interim and annual periods ending after September 15, 2009. The Company is currently evaluating the effects of the adoption of SFAS No. 168 and will revise the references within future
financial statements for the Codification.

Statement of Financial Accounting Standards (SFAS) No. 141 (SFAS
141R), Business Combinations (Revised 2007).SFAS 141R replaces SFAS 141, Business Combinations, and applies to all transactions and other events in which one entity obtains control over one or more other
businesses. SFAS 141R requires an acquirer, upon initially obtaining control of another entity, to recognize the assets, liabilities and any non-controlling interest in the acquiree at fair value as of the acquisition date. Contingent
consideration is required to be recognized and measured at fair value on the date of acquisition rather than at a later date when the amount of that consideration may be determinable beyond a reasonable doubt. This fair value approach replaces the
cost-allocation process required under SFAS 141 whereby the cost of an acquisition was allocated to the individual assets acquired and liabilities assumed based on their estimated fair value. SFAS 141R requires acquirers to expense
acquisition-related costs as incurred rather than allocating such costs to the assets acquired and liabilities assumed, as was previously the case under SFAS 141. Under SFAS 141R, the requirements of SFAS 146, Accounting for Costs
Associated with Exit or Disposal Activities, would have to be met in order to accrue for a restructuring plan in purchase accounting. Pre-acquisition contingencies are to be recognized at fair value, unless it is a non-contractual contingency
that is not likely to materialize, in which case, nothing should be recognized in purchase accounting and, instead, that contingency would be subject to the probable and estimable recognition criteria of SFAS 5, Accounting for
Contingencies. SFAS 141R was effective for the Company on January 1, 2009. The adoption of SFAS 141R will have a significant impact on the Companys accounting for business combinations closing on or after January 1, 2009.

Financial Accounting Standards Board Staff Positions and Interpretations

In April 2009, the FASB issued three Final Staff Positions (FSPs) to provide additional guidance and disclosures regarding fair value measurements and
impairments of securities:

FSP FAS 157-4. Determining Fair Value When the Volume and Level of Activity for the Asset or Liability
Have Significantly Decreased and Identifying Transactions That Are Not Orderly, provides guidance for estimating fair value when the volume and level of activity for an asset or liability have significantly decreased. The
Companys adoption of FSP FAS 157-4 did not have a material impact on the Companys consolidated financial statements.

FSP FAS
115-2 and FAS 124-2, Recognition and Presentation of Other-Than-Temporary Impairments,amends the other-than-temporary impairment guidance for debt securities to make the guidance more operational and to improve the presentation and
disclosure of other-than-temporary impairments on debt and equity securities in financial statements. The adoption of FSP FAS 115-2 and FAS 124-2 did not have a material impact on the Companys consolidated financial statements.

FSP FAS 107-1 and APB 28-1, Interim Disclosures about Fair Value of Financial Instruments,
requires disclosure about fair value of financial instruments for interim reporting periods of publicly traded companies as well as in annual financial statements. The expanded disclosure requirements for FSP FAS 107-1 are effective for the
Companys quarterly financial statements for the three months ended June 30, 2009 and are included in Note 4  Fair Value Disclosure.



|4. | FAIR VALUE DISCLOSURES
|-- | ----------------------

Effective January 1, 2008,
the Company adopted SFAS 157, Fair Value Measurements, which defines fair value, addresses aspects of the expanding application of fair value accounting and establishes a consistent framework for measuring fair value. Fair values represent
the estimated price that would be received from selling an asset or paid to transfer a liability, otherwise knows as an exit price.

Fair
Value Hierarchy

SFAS 157 specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are
observable or unobservable. In accordance with SFAS 157, these inputs are summarized in the three broad levels listed below:



| |  |  | Level 1  Quoted prices in active markets for identical assets or liabilities. Level 1 assets include US Treasury securities that are highly liquid and are
actively traded in over-the-counter markets.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 2  Other significant observable inputs (including quoted prices in active markets for similar assets or liabilities) or other inputs that are observable
or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets include US government and agency mortgage-backed debt securities, corporate securities, municipal bonds and CRA funds.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 3  Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level
3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair values requires significant
management judgment or estimation.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In determining the appropriate levels, the Company performs a detailed analysis of
the assets and liabilities that are subject to SFAS 157.

The following table presents fair value measurements on a recurring basis as of
June 30, 2009:



|                                              |  |                        |   |         |   |         |  |       |   |  |   |

|                                              |  |                        |   |         |   |         |  |       |   |  |   |        
|                                              |  |                        |   |

|                                              |  |                        |   |         |   |         |  |       |   |  |   |        

Certain assets and liabilities are measured at fair value on a non-recurring basis; that is, the
instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). These instruments include other real estate owned,
repossessed assets and impaired loans per SFAS 114, Accounting by Creditors for Impairment of a Loanan amendment of FASB Statements No. 5 and 15. For the three months ended June 30, 2009, the Company had additions to impaired
loans of $645,000 and additions to other real estate owned of $8.1 million, which were outstanding June 30, 2009. The remaining financial assets and financial liabilities measured at fair value on a non-recurring basis that were recorded in
2009 and remained outstanding at June 30, 2009 were not significant.

Disclosures of the estimated fair value amounts of financial instruments have been determined by the
Company using available market information and appropriate valuation methodologies. However, considerable judgment is necessarily required in interpreting market data to develop the estimates of fair value. Accordingly, the estimates presented
herein are not necessarily indicative of the amounts the Company could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies could have a material effect on the estimated fair value amounts.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is
practicable to estimate that value:

Cash and Cash EquivalentsFor these short-term instruments, the carrying amount is a
reasonable estimate of fair value.

Federal Funds SoldThe carrying amount is a reasonable estimate of fair value.

SecuritiesFor securities held as investments, fair value equals quoted market price, if available. If a quoted market price is not
available, fair value is estimated using quoted market prices for similar securities.

Loans Held for InvestmentFor certain
homogeneous categories of loans (such as some residential mortgages and other consumer loans), fair value is estimated by discounting the future cash flows using the risk-free Treasury rate for the applicable maturity, adjusted for servicing and
credit risk. The carrying value of variable rate loans approximates fair value because the loans reprice frequently to current market rates.

DepositsThe fair value of demand deposits, savings accounts and certain money market deposits is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated using
the rates currently offered for deposits of similar remaining maturities.

Junior Subordinated DebenturesThe fair value of the
junior subordinated debentures was calculated using the quoted market prices, if available. If a quoted market prices are not available, fair value is estimated using quoted market prices for similar subordinated debentures.

Other BorrowingsRates currently available to the Company for debt with similar terms and remaining maturities are used to estimate the fair
value of existing debt using a discounted cash flows methodology.

Securities Sold Under Repurchase AgreementsThe fair value
of securities sold under repurchase agreements is the amount payable on demand at the reporting date.

Off-Balance Sheet Financial
InstrumentsThe fair value of commitments to extend credit and standby letters of credit is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreement and the
present creditworthiness of the counterparties.

The Companys off-balance sheet commitments are funded at current market rates at the date
they are drawn upon. It is managements opinion that the fair value of these commitments would approximate their carrying value, if drawn upon.

The fair value estimates presented herein are based on pertinent information available to management as of the dates indicated. Although management is not aware of any factors that would significantly affect the
estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since those dates and, therefore, current estimates of fair value may differ significantly from the amounts presented
herein.

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 real estate valuations, 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 finalizing the valuation, core deposit intangibles are identified and
reclassified from goodwill to core deposit intangibles on the balance sheet. This reclassification has no effect on total assets, liabilities, shareholders equity, net income or cash flows. Management performs an evaluation annually, and more
frequently if a triggering event occurs, 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 June 30, 2009, there were no impairments recorded on
goodwill or other intangibles.

During the six months ended June 30, 2009, the Company completed the valuation of the assets
acquired and liabilities assumed in the Franklin Bank acquisition and allocated $7.3 million to core deposit intangibles and allocated $7.2 million to certificates of deposit. Both amounts had previously been reflected in goodwill as of
December 31, 2008 pending the completed valuations.

Core deposit intangibles are amortized on an accelerated basis over their
estimated lives, which the Company believes is between 8 and 10 years. Gross core deposit intangibles outstanding were $76.7 million and $69.5 million at June 30, 2009 and December 31, 2008, respectively. Net core deposit intangibles
outstanding were $40.3 million and $38.2 million at the same dates, respectively. Amortization expense related to intangible assets totaled $2.5 million for both the three months ended June 30, 2009 and 2008, respectively, and $5.2 million and
$5.0 million for the six months ended June 30, 2009 and 2008, respectively. The increase in amortization expense was primarily due to the core deposit intangibles from the acquisition of Franklin Bank. The estimated aggregate future
amortization expense for intangible assets remaining as of June 30, 2009 is as follows (dollars in thousands):

|6. | STOCK BASED COMPENSATION
|-- | ------------------------

At June 30, 2009, the
Company had three stock-based employee compensation plans adopted by the Company and five stock option plans assumed in connection with acquisitions under which no additional options will be granted. Two of the three plans adopted by the Company
have expired and therefore no additional awards may be issued under the plans. The Company accounts for stock-based employee compensation plans using the fair value-based method of accounting in accordance with Statement of Financial Accounting
Standards No. 123R, Share-Based Payment (Revised 2004) (SFAS 123R).SFAS 123R was effective for companies in 2006, however, the Company had been recognizing compensation expense since January 1, 2003. The Companys
results of operations reflect compensation expense for all employee stock-based compensation, including the unvested portion of stock options granted prior to 2003. 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. The Company recognized $620,000 and
$641,000 in stock-based compensation expense for the six months ended June 30, 2009 and 2008, respectively, and $294,000 and $393,000 in stock-based compensation expense for the three months ended June 30, 2009 and 2008, respectively.
There was approximately $146,000 and $122,000 of income tax benefit recorded for the stock-based compensation expense for the six months ended June 30, 2009 and 2008, respectively, and $66,000 and $87,000 of income tax benefit recorded for the
stock-based compensation expense for the three months ended June 30, 2009 and 2008, respectively.

The Company has granted shares of
common stock (restricted stock) to certain directors and associates under the Companys 2004 Stock Incentive Plan. The awardee is not entitled to the shares until they vest, which is generally over a 1 to 5 year period, but the
awardee is entitled to receive dividends on and vote the shares prior to vesting. The shares granted do not have a cost to the awardee and the only requirement of vesting is continued service to the Company. Compensation cost related to restricted
stock is calculated based on the market price of the shares at the date of grant. If the awardee leaves the Company before the shares vest, the unvested shares are forfeited. As of June 30, 2009, there were 58,656 shares of restricted stock
outstanding with a weighted average grant date fair value of $32.20.

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:

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 June 30, 2009 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:

|8. | SUBSEQUENT EVENTS
|-- | -----------------

The Company adopted SFAS 165 on
June 15, 2009 which requires management to evaluate, as of each reporting period, events or transactions that occur after the balance sheet date through the date that the financial statements are issued or are available to be issued. It does
not change the recognition and disclosure requirements in AU Section 560 for Type I and Type II subsequent events; however, SFAS 165 refers to them as recognized (Type I) and nonrecognized subsequent events (Type II). The Company must consider
supplementing historical financial statements with the pro forma impact of nonrecognized subsequent events if the event is so significant that disclosure of the event could be best made through the use of pro forma financial data. Statement 165 is
effective prospectively for interim or annual financial periods ending after June 15, 2009. The adoption of this pronouncement did not have a significant impact on the Companys financial statements. The Company evaluated all events and
transactions that occurred after the balance sheet date through August 10, 2009 and determined no reportable subsequent events existed.

financial statements and accompanying notes and other detailed information appearing in the Companys Annual Report on Form 10-K for the year ended December 31, 2008.

OVERVIEW

The Company, a Texas corporation, 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® (Prosperity Bank® or the Bank). The Bank provides a wide array of financial products and services to small and medium-sized businesses and consumers. As of
June 30, 2009, the Bank operated one hundred fifty-eight (158) full-service banking locations; with fifty-one (51) in the Greater Houston Consolidated Metropolitan Statistical Area (CMSA), twenty-seven (27) in the
South Texas area including Corpus Christi and Victoria, thirty-six (36) in the Central Texas area including Austin and Bryan/College Station,, twenty (20) in East Texas and twenty-four (24) 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 (281) 269-7199. 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 noninterest 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.

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 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 January 10, 2008, the Company purchased six (6) branches of Banco Popular North America. On June 1, 2008 the Company purchased 1stChoice Bancorp, Inc. (the 1stChoice acquisition) which added one (1) banking center after consolidation. On November 7, 2008, the Bank assumed
approximately $3.6 billion of deposits and acquired certain assets from the Federal Deposit Insurance Corporation (FDIC), acting in its capacity as

##### Table of Contents

receiver for Franklin Bank (the Franklin acquisition or the Franklin Bank acquisition). The transaction added thirty-three
(33) banking centers after consolidations with existing Prosperity Bank locations.

Total assets were $8.84 billion at June 30,
2009 compared with $9.07 billion at December 31, 2008, a decrease of $233.8 million or 2.6%. Total loans were $3.45 billion at June 30, 2009 compared with $3.57 billion at December 31, 2008, a decrease of $115.7 million or 3.2%. Total
deposits were $7.26 billion at June 30, 2009 compared with $7.30 billion December 31, 2008, a decrease of $45.4 million or 0.6%. Shareholders equity increased $43.6 million or 3.5%, to $1.30 billion at June 30, 2009 compared
with $1.26 billion at December 31, 2008.

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, 2008. 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 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 inherent in the Companys loan portfolio. Based on an evaluation of the loan portfolio, management presents a quarterly 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 at least an annual impairment test 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 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 between eight and ten 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, 2008, management
does not believe any of its goodwill is impaired as of June 30, 2009. While the Company believes no impairment existed at June 30, 2009 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 accounts for stock-based employee compensation plans using the fair value-based method of
accounting in accordance with SFAS No. 123R, Share-Based Payment (Revised 2004) (SFAS 123R).SFAS 123R was effective for companies in 2006, however, the Company had been recognizing compensation expense since January 1,
2003. The Companys results of operations reflect compensation expense for all employee stock-based compensation, including the unvested portion of stock options granted prior to 2003. 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 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 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



19

##### Table of Contents

financial condition and near-term prospects of the issuer, as well as the value of any security the Company 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 $26.5 million ($0.57 per common share on a diluted basis)
for the quarter ended June 30, 2009 compared with $23.4 million ($0.52 per common share on a diluted basis) for the quarter ended June 30, 2008, an increase in net income of $3.1 million or 13.1%. The Company posted returns on average
common equity of 8.18% and 7.96%, returns on average assets of 1.20% and 1.43% and efficiency ratios of 48.98% and 46.50% for the quarters ended June 30, 2009 and 2008, respectively. The efficiency ratio is calculated by dividing total
noninterest expense (excluding credit loss provisions) by net interest income plus noninterest income (excluding net gains and losses on the sale of securities and assets and impairment write-down on securities). Additionally, taxes are not part of
this calculation.

For the six months ended June 30, 2009, net income available to common shareholders was $52.0 million ($1.13 per
common share on a diluted basis) compared with $46.4 million ($1.04 per common share on a diluted basis) for the same period in 2008, an increase in net income of $5.6 million or 12.1%. The Company posted returns on average common equity of 8.12%
and 7.99%, returns on average assets of 1.17% and 1.43% and efficiency ratios of 49.22% and 45.78% for the six months ended June 30, 2009 and 2008, respectively.

Net Interest Income

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.

Net interest income before the provision for credit losses was $75.5 million for the
quarter ended June 30, 2009 compared with $54.0 million for the quarter ended June 30, 2008, an increase of $21.6 million, or 39.9%. Net interest income increased as a result of an increase in average interest-earning assets to $7.56
billion for the quarter ended June 30, 2009 compared with $5.37 billion for the quarter ended June 30, 2008, an increase of $2.19 billion, or 40.8%. The increase in average earning assets was primarily attributable to increases in average
securities primarily attributable to the Franklin Bank acquisition.

The net interest margin on a tax equivalent basis decreased to 4.04%
for the quarter ended June 30, 2009 compared with 4.10% for the quarter ended June 30, 2008. The average rate paid on interest-bearing liabilities decreased 93 basis points from 2.76% for the quarter ended June 30, 2008 compared with
1.83% for the quarter ended June 30, 2009. The average yield on earning assets decreased 69 basis points from 6.14% for the quarter ended June 30, 2008 compared with 5.45% for the quarter ended June 30, 2009. The volume of
interest-bearing liabilities increased $1.87 billion and the volume of interest-earning assets increased $2.19 billion for the same periods.

Net interest income before the provision for credit losses increased $43.6 million, or 41.2%, to $149.6 million for the six months ended June 30, 2009 compared with $106.0 million for the same period in 2008. This increase was mainly
attributable to higher average interest-earning assets resulting from an increase in average loans and securities due to the Franklin Bank acquisition. The net interest margin on a tax equivalent basis decreased to 4.01% compared with 4.07% for the
same periods principally due to a 102 basis point decrease in the average rate paid on interest-bearing liabilities from 2.99% for the six months ended June 30, 2008 compared with 1.97% for the six months ended June 30, 2009 and a 77 basis
point decrease in the average yield on earning assets from 6.30% for the six months ended June 30, 2008 compared with 5.53% for the six months ended June 30, 2009.

##### Table of Contents

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 distinguishes between the increase (decrease) related to changes in outstanding balances and the volatility of interest rates. For purposes of these tables, changes
attributable to both rate and volume that 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 Companys 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 process 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 $6.9 million provision for credit losses for the quarter ended June 30, 2009 and a $1.0 million provision for the quarter
ended June 30, 2008. The increase was due to an increase in net charge-offs to $3.5 million for the quarter ended June 30, 2009 compared with net charge-offs of $1.2 million for the quarter ended June 30, 2008. The Company made a
$13.0 million provision for credit losses for the six months ended June 30, 2009 and a $2.2 million provision for the six months ended June 30, 2008. The increase was due to an increase in net charge-offs to $7.4 million for the six months
ended June 30, 2009 compared with $2.8 million for the six months ended June 30, 2008.

Noninterest Income

The Companys primary sources of noninterest income are service charges on deposit accounts and other banking service related
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 $15.1 million for the three months ended June 30, 2009 compared with $13.1 million for the same period in 2008, an increase of $2.1 million, or 15.8%. Noninterest
income increased $4.4 million, or 17.1%, to $30.1 million for the six months ended June 30, 2009 compared with $25.7 million for the same period in 2008. Both increases were primarily due to an increase in insufficient funds charges and
customer service charges which resulted from an increase in the number of accounts due to the Franklin and 1stChoice acquisitions. As of June 30, 2009, approximately 108,000 deposit accounts were attributed to these two acquisitions.

The net gain on sale of ORE was $415,000 for the three months ended June 30, 2009 compared with a net loss of $478,000 for the three months ended June 30, 2008. The net gain on sale of ORE was $437,000 for
the six months ended June 30, 2009 compared with a net loss of $439,000 for the same period in 2008.

Other noninterest income
decreased $72,000 or 13.1% to $479,000 for the three months ended June 30, 2009 compared with $551,000 for the same period in 2008. Other noninterest income increased $591,000 or 49.9% to $1.8 million for the six months ended June 30, 2009
compared with $1.2 million for the same period in 2008. The increase was primarily due to loan servicing income paid by the FDIC related to loans of Franklin Bank that the Bank serviced on behalf of the FDIC but did not purchase. The loan servicing
agreement ended in April 2009.

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

million for the quarter ended June 30, 2009 compared with $16.8 million for the quarter ended June 30, 2008, an increase of $3.7 million, or 22.3%. The increase was principally due to annual employee pay increases and the Franklin Bank and
1stChoice acquisitions. For the six months ended June 30, 2009, salaries and
employee benefit expenses were $43.1 million, an increase of $10.3 million or 31.2% compared with $32.9 million for the six months ended June 30, 2008. The increase was principally due to annual employee pay increases and the Franklin Bank and

1,502.9%, to $8.8 million for the six months ended June 30, 2009 compared with $546,000 during the same period in 2008. The increase was due to higher rates charged by the FDIC for deposit insurance and an increase in deposits due to the
Franklin acquisition. In addition to the increase in the regular FDIC assessment rates, the FDIC imposed an emergency special assessment of 5 basis points on total assets minus total Tier 1 capital as of June 30, 2009. The special
assessment will be payable on September 30, 2009.

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 June 30, 2009, the allowance for credit losses amounted to $42.6 million or 1.23% of total loans compared with $37.0 million or 1.04% of total loans at December 31, 2008.

Set forth below is an analysis of the allowance for credit losses for the six months ended June 30, 2009 and the year ended December 31, 2008:

Management evaluates securities for other-than-temporary impairment (OTTI) at least on
a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. The investment securities portfolio is evaluated for OTTI by segregating the portfolio into two general segments and applying the appropriate OTTI
model. Investment securities classified as available for sale or held-to-maturity are generally evaluated for OTTI under Statement of Financial Accounting Standards (SFAS) No. 115, Accounting for Certain Investments in Debt and
Equity Securities. However, certain purchased beneficial interests, including non-agency mortgage-backed securities, asset-backed securities, and collateralized debt obligations, that had credit ratings at the time of purchase of below AA are
evaluated using the model outlined in EITF Issue No. 99-20, Recognition of Interest Income and Impairment on Purchased Beneficial Interests and Beneficial Interests that Continue to be Held by a Transfer in Securitized Financial Assets.The Company currently does not own any securities that are accounted for under EITF 99-20.

In determining OTTI under the SFAS
No. 115 model, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether
the market decline was affected by macroeconomic conditions, and (4) whether the entity has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The assessment
of whether an other-than-temporary decline exists involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time. If applicable, the second segment of the portfolio uses the OTTI
guidance provided by EITF 99-20 that is specific to purchased beneficial interests that, on the purchase date, were rated below AA. Under the EITF 99-20 model, the Company compares the present value of the remaining cash flows as estimated at the
preceding evaluation date to the current expected remaining cash flows. An OTTI is deemed to have occurred if there has been an adverse change in the remaining expected future cash flows.

When OTTI occurs under either model, the amount of the OTTI recognized in earnings depends on whether an entity intends to sell the security or more
likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss. If an entity intends to sell or more likely than not will be required to sell the security before recovery of its
amortized cost basis less any current-period credit loss, the OTTI shall be recognized in earnings equal to the entire difference between the investments amortized cost basis and its fair value at the balance sheet date. If an entity does not
intend to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis less any current-period loss, the OTTI shall be separated into the amount representing
the credit loss and the amount related to all other factors. The amount of the total OTTI related to the credit loss is determined based on the present value of cash flows expected to be collected and is recognized in earnings. The amount of the
total OTTI related to other factors shall be recognized in other comprehensive income, net of

Management believes they do not intend to sell the debt security or more likely than not will be required to sell the debt security before
its anticipated recovery, at which time the Company will receive full value for the securities. Furthermore, management has the ability and intent to hold the securities classified as available for sale that were in a loss position as of
June 30, 2009 for a period of time sufficient for an entire recovery of the cost basis of the securities. The unrealized losses are largely due to increases in market interest rates over the yields available at the time the underlying
securities were purchased. The fair value is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline. Management does not believe any of the securities are impaired due to
reasons of credit quality. Accordingly, as of June 30, 2009, management believes any impairment in the Companys securities are temporary and no impairment loss has been realized in the Companys consolidated income statement.

The following tables present the amortized cost and fair value of securities classified as available for sale at June 30, 2009:

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 largest source of funds is deposits and its largest use of funds is loans. The Company does not expect a change in the source or use of its funds in the future. 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, has generally created an adequate liquidity position.

As of June 30, 2009, the Company had outstanding $543.7 million in
commitments to extend credit and $16.2 million in commitments associated with outstanding standby letters of credit. Since commitments associated with letters of credit and

commitments to extend credit may expire unused, the total outstanding may not necessarily reflect the actual future cash funding requirements.

The Company has no exposure to future cash requirements associated with known uncertainties or capital expenditures of a material nature.

Asset liquidity is provided by cash and assets which are readily marketable or which will mature in the near future. As of June 30, 2009, the
Company had cash and cash equivalents of $271.3 million compared with $228.6 million at December 31, 2008, an increase of $42.7 million. The increase was primarily due to net repayments of other borrowings of $200.0 million, a decrease in
deposits of $51.8 million, purchases of securities of $953.0 million, purchases of premises and equipment of $31.1 million and a decrease in other liabilities of $30.4 million, partially offset by proceeds from the maturities and repayments of
securities of $1.14 billion, a decrease in loans of $91.2 million, net earnings of $52.0 million, proceeds from the sale of bank premises, equipment and ORE of $12.9 million and a decrease in other assets of $10.7 million.

Contractual Obligations

The following table
summarizes the Companys contractual obligations and other commitments to make future payments as of June 30, 2009 (other than deposit obligations). The payments do not include pre-payment options that may be available to the Company. 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 June 30, 2009 are summarized below. Payments for junior subordinated
debentures include interest of $82.3 million that will be paid over the future periods. The future interest payments were calculated using the current rate in effect at June 30, 2009. With respect to floating interest rates, the payments were
determined based on the 3-month LIBOR in effect at June 30, 2009. The current principal balance of the junior subordinated debentures at June 30, 2009 was $92.3 million. Payments for FHLB notes payable include interest of $5.8 million that
will be paid over the future periods. 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 June 30, 2009 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:

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. As of June 30, 2009, the Companys Tier 1 risk-based capital,
total risk-based capital and leverage capital ratios were 11.24%, 12.28% and 5.81%, respectively. As of June 30, 2009, the Banks risk-based capital ratios were above the levels required for the Bank to be designated as well
capitalized by the FDIC, with Tier-1 risk-based capital, total risk-based capital and leverage capital ratios of 10.97%, 12.02% and 5.66%, respectively.

on balances above $250,000 through December 31, 2013. The Company and the Bank elected to not participate in the U.S. Department of Treasury Capital Purchase Program, which is a part of the Troubled Asset Relief Program.



|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 2, 2009 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, as amended (the Exchange Act))
were effective as of the end of the period covered by this report.

Changes in internal control over financial reporting. There were
no changes in the Companys internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended June 30, 2009 that have materially affected, or are
reasonably likely to materially affect, the Companys internal control over financial reporting.
