NOTES TO INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

JUNE 30, 2010

(UNAUDITED)

1. BASIS OF PRESENTATION

The interim condensed 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, LLC. All significant inter-company transactions and balances have been eliminated.

The accompanying unaudited interim condensed 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, 2009. Operating results for the six-month period ended June 30, 2010 are not necessarily indicative of the results that may be expected for the year ending December 31, 2010 or any other period.

2. INCOME PER COMMON SHARE

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


	Three Months Ended June 30,				Six Months Ended June 30,
	2010		2009		2010		2009
	(In thousands, except per share amounts)

Net income available to common shareholders	$	31,746	$	26,510	$	62,744	$	51,988


Weighted average common shares outstanding		46,610		46,105		46,581		46,097
Potential dilutive common shares		244		120		276		49

Weighted average common shares and equivalents outstanding		46,854		46,225		46,857		46,146


Basic earnings per common share	$	0.68	$	0.57	$	1.35	$	1.13

Diluted earnings per common share	$	0.68	$	0.57	$	1.34	$	1.13

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, 2010 or 2009 that would have had an anti-dilutive effect on the above computation.

3. NEW ACCOUNTING STANDARDS

Accounting Standards Updates

Accounting Standards Update (ASU) No. 2009-16, “Transfers and Servicing (Topic 860)—Accounting for Transfers of Financial Assets.” ASU 2009-16 amends prior accounting guidance to enhance reporting about transfers of financial assets, including securitizations, and where companies have continuing exposure to the risks related to transferred financial assets. ASU 2009-16 eliminates the concept of a “qualifying special-purpose entity” and changes the requirements for derecognizing financial assets. ASU 2009-16 also requires additional disclosures about all continuing involvements with transferred financial assets including information about gains and losses resulting from transfers during the period. The provisions of ASU 2009-16 became effective on January 1, 2010 and did not have a significant impact on the Company’s financial statements.

PROSPERITY BANCSHARES, INC. ^® AND SUBSIDIARIES

NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

JUNE 30, 2010

(UNAUDITED)

ASU No. 2009-17, “Consolidations (Topic 810)—Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities.” ASU 2009-17 amends prior guidance to change 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. ASU 2009-17 requires additional disclosures about the reporting entity’s involvement with variable-interest entities and any significant changes in risk exposure due to that involvement as well as its effect on the entity’s financial statements. ASU No. 2010-10, “Consolidations (Topic 810),” deferred the effective date of ASU 2009-17 for a reporting entity’s interests in investment companies. The provisions of ASU 2009-17 became effective on January 1, 2010 and did not have a significant impact on the Company’s financial statements.

ASU No. 2010-06, “Fair Value Measurements and Disclosures (Topic 820)—Improving Disclosures About Fair Value Measurements.” ASU 2010-06 requires expanded disclosures related to fair value measurements including (i) the amounts of significant transfers of assets or liabilities between Levels 1 and 2 of the fair value hierarchy and the reasons for the transfers, (ii) the reasons for transfers of assets or liabilities in or out of Level 3 of the fair value hierarchy, with significant transfers disclosed separately, (iii) the policy for determining when transfers between levels of the fair value hierarchy are recognized and (iv) for recurring fair value measurements of assets and liabilities in Level 3 of the fair value hierarchy, a gross presentation of information about purchases, sales, issuances and settlements. ASU 2010-06 further clarifies that (i) fair value measurement disclosures should be provided for each class of assets and liabilities (rather than major category), which would generally be a subset of assets or liabilities within a line item in the statement of financial position and (ii) a company should provide disclosures about the valuation techniques and inputs used to measure fair value for both recurring and nonrecurring fair value measurements for each class of assets and liabilities included in Levels 2 and 3 of the fair value hierarchy. The disclosures related to the gross presentation of purchases, sales, issuances and settlements of assets and liabilities included in Level 3 of the fair value hierarchy will be required for the Company beginning January 1, 2011. The remaining disclosure requirements and clarifications made by ASU 2010-06 became effective for the Company on January 1, 2010 (see Note 4 —Fair Value), and did not have a significant impact on the Company’s financial statements.

ASU No. 2010-20, “Receivables (Topic 830)—Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses.” ASU 2010-20 requires entities to provide disclosures designed to facilitate financial statement users’ evaluation of (i) the nature of credit risk inherent in the entity’s portfolio of financing receivables, (ii) how that risk is analyzed and assessed in arriving at the allowance for credit losses and (iii) the changes and reasons for those changes in the allowance for credit losses. Disclosures must be disaggregated by portfolio segment, the level at which an entity develops and documents a systematic method for determining its allowance for credit losses, and class of financing receivable, which is generally a disaggregation of portfolio segment. The required disclosures include, among other things, a rollforward of the allowance for credit losses as well as information about modified, impaired, non-accrual and past due loans and credit quality indicators. ASU 2010-20 will be effective for the Company’s financial statements as of December 31, 2010, as it relates to disclosures required as of the end of a reporting period. Disclosures that relate to activity during a reporting period will be required for the Company’s financial statements that include periods beginning on or after January 1, 2011.

4. FAIR VALUE

Effective January 1, 2008, the Company adopted FASB ASC Topic 820, Fair Value Measurement and Disclosures. ASC Topic 820, which defines fair value, addresses aspects of the expanding application of fair value accounting and establishes a consistent framework for measuring fair value. Fair value represents the estimated price that would be received from selling an asset or paid to transfer a liability, otherwise known as an “exit price”.

NOTES TO INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

JUNE 30, 2010

(UNAUDITED)

Fair Value Hierarchy

ASC Topic 820 specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. In accordance with ASC Topic 820, 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 U.S. 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. The Company’s Level 2 assets include U.S. 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 ASC Topic 820.

The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of June 30, 2010, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value:


	Level 1		Level 2		Level 3		Total

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 ASC Topic 310, Receivables. For the six months ended June 30, 2010, the Company had additions to impaired loans of $15.9 million and additions to other real estate owned of $19.9 million, of which $4.4 million and $9.3 million were outstanding June 30, 2010, respectively. The remaining financial assets and financial liabilities measured at fair value on a non-recurring basis that were recorded in 2010 and remained outstanding at June 30, 2010 were not significant.

The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. FASB ASC Topic 820 establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs

These fair value disclosures represent the Company’s estimates based on relevant market information and information about the financial instruments. Fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of the various instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in the above methodologies and assumptions could significantly affect the estimates.

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 fixed rate loans and 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 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.

FASB ASC Topic 825, Financial Instruments, requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis. The carrying amount and estimated fair values of the Company’s financial instruments are as follows:


	June 30, 2010
	Carrying Amount		Estimated Fair Value
	(Dollars in thousands)
Financial assets:
Cash and due from banks	$	148,395	$	148,395
Federal funds sold		823		823
Available for sale securities		510,305		510,305

Other borrowings		154,935		156,463
Securities sold under repurchase agreements		93,060		93,060
Junior subordinated debentures		92,265		90,352

Total	$	8,154,189	$	8,173,054

The Company’s off-balance sheet commitments, which total $477.3 million at June 30, 2010, 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 at June 30, 2010. 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.

5. GOODWILL AND CORE DEPOSIT INTANGIBLES

Changes in the carrying amount of the Company’s goodwill and core deposit intangibles (CDI) for the six months ended June 30, 2010 were as follows:


	Goodwill		Core Deposit Intangibles

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 or liabilities. 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, 2010, there were no impairments recorded on goodwill or other intangibles.

Although the Bank completed the U.S. Bank branch acquisition in March 2010 and the First Bank branch acquisition in May 2010, the Company has not yet finalized the allocation of the purchase price for each respective acquisition.

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 $79.3 million and $76.7 million at June 30, 2010 and December 31, 2009, respectively. Net core deposit intangibles outstanding were $33.4 million and $35.4 million at the same dates, respectively. Amortization expense related to intangible assets totaled $2.3 million and $2.5 million for the three months ended June 30, 2010 and 2009, respectively, and $4.6 million and $5.2 million for the six months ended June 30, 2010 and 2009, respectively. The estimated aggregate future amortization expense for intangible assets remaining as of June 30, 2010 is as follows (dollars in thousands):


Remaining 2010	$	4,467

2011		7,806

2012		6,370

2013		4,485

2014		3,331

Thereafter		6,930


Total	$	33,389

6. STOCK BASED COMPENSATION

At June 30, 2010, the Company had three stock-based employee compensation plans and four 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 those plans. The Company accounts for stock-based employee compensation plans using the fair value-based method of accounting in accordance with ASC Topic 718. ASC Topic 718 was effective for companies in 2006; however, the Company has been recognizing compensation expense since January 1, 2003. The Company recognized $1.5 million and $620,000 in stock-based compensation expense for the six months ended June 30, 2010 and 2009, respectively, and $692,000 and $294,000 in stock-based compensation expense for the three months ended June 30, 2010 and 2009, respectively. There was approximately $469,000 and $146,000 of income tax benefit recorded for the stock-based compensation expense for the six months ended June 30, 2010 and 2009, respectively, and $217,000 and $66,000 of income tax benefit recorded for the stock-based compensation expense for the three months ended June 30, 2010 and 2009, 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, 2010, there were 356,905 shares of restricted stock outstanding with a weighted average grant date fair value of $36.50.

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:


	June 30,
	2010		2009
Expected life (years)	5.14		5.10
Risk free interest rate	3.88	%	4.11	%
Volatility	21.21	%	21.19	%
Dividend yield	1.26	%	1.22	%

A summary of changes in outstanding vested and unvested options during the six months ended June 30, 2010 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	856		$	25.88
Options granted	—			—

Options exercisable, end of period	424		$	23.87	3.67	$	4,612

No options were granted during the six months ended June 30, 2010 and a total of 12,500 options at a weighted average exercise price of $29.08 were granted during the six months ended June 30, 2009. The total intrinsic value of the options exercised during the six month periods ended June 30, 2010 and 2009 was $986,000 and $355,000, respectively. The total fair value of shares vested during the six month periods ended June 30, 2010 and 2009 was $124,000 and $113,000, respectively.

There was no tax benefit realized from option exercises of the stock-based compensation arrangements during the six month periods ended June 30, 2010 and 2009.

As of June 30, 2010, there was $11.9 million of total unrecognized compensation expense related to non-vested stock-based compensation arrangements. That cost is expected to be recognized over a weighted average period of 3.1 years.

7. CONTRACTUAL OBLIGATIONS AND OFF-BALANCE SHEET ITEMS

Contractual Obligations

The following table summarizes the Company’s contractual obligations and other commitments to make future payments as of June 30, 2010 (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, 2010 are summarized below. Payments for junior subordinated debentures include interest of $72.6 million that will be paid over the future periods. The future interest payments were calculated using the current rate in effect at June 30, 2010. With respect to floating interest rates, the payments were determined based on the 3-month LIBOR in effect at June 30, 2010. The current principal balance of the junior subordinated debentures at June 30, 2010 was $92.3 million. Payments for FHLB notes payable include interest of $4.6 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, 2010 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:

PASSAGE OF DODD-FRANK ACT

In July 2010, Congress enacted regulatory reform legislation known as the Dodd–Frank Wall Street Reform and Consumer Protection Act (the “Dodd–Frank Act”), which the President signed into law on July 21, 2010. Many aspects of the Dodd–Frank Act are subject to further rulemaking and will take effect over several years, making it difficult to anticipate the overall financial impact to the Company, the Bank or across the industry. This new law broadly affects the financial services industry by implementing changes to the financial regulatory landscape aimed at strengthening the sound operation of the financial services sector, including provisions that, among other things, will:

•

Create a new agency, the Consumer Financial Protection Bureau, responsible for implementing, examining and enforcing compliance with federal consumer financial laws;

•

Apply the same leverage and risk–based capital requirements that apply to insured depository institutions to most bank holding companies, which, among other things, will require the Company to deduct all trust preferred securities issued on or after May 19, 2010 from the Company’s Tier 1 capital (existing trust preferred securities issued prior to May 19, 2010 for all bank holding companies with less than $15.0 billion in total consolidated assets as of December 31, 2009 are exempt from this requirement);

•

Require the Company to be well–capitalized and well–managed in order to acquire banks located outside its home state;

•

Broaden the base for FDIC insurance assessments from the amount of insured deposits to average total consolidated assets less average tangible equity during the assessment period, which generally is expected to result in an increase in the level of assessments;

•

Permanently increase FDIC deposit insurance to $250,000 and provide unlimited FDIC deposit insurance beginning December 31, 2010 until January 1, 2013 for noninterest bearing demand transaction accounts at all insured depository institutions;

•

Amend the Electronic Fund Transfer Act to, among other things, give the Federal Reserve the authority to establish rules regarding interchange fees charged for electronic debit transactions by payment card issuers having assets over $10 billion and to enforce a new statutory requirement that such fees be reasonable and proportional to the actual cost of a transaction to the issuer;

•

Permit the Bank to engage in de novo interstate branching if the laws of the state where the new branch is to be established would permit the establishment of the branch if the Bank were chartered by such state;

•

Implement corporate governance revisions, including with regard to executive compensation and proxy access by shareholders, that apply to all public companies, not just financial institutions; and

•

Repeal the federal prohibitions on the payment of interest on demand deposits, thereby permitting depository institutions to pay interest on business transaction and other accounts.

The Company’s management is actively reviewing the provisions of the Dodd–Frank Act and assessing its probable impact on the business, financial condition, and results of operations of the Company and the Bank. Provisions in the legislation that affect deposit insurance assessments, payment of interest on demand deposits and interchange fees could increase the costs associated with deposits as well as place limitations on certain revenues those deposits may generate. Provisions in the legislation that revoke the Tier 1 capital treatment of newly issued trust preferred securities could require the Company to seek other sources of capital in the future.

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, 2010, the Bank operated one hundred seventy-five (175) full-service banking locations; with sixty (60) in the Houston area, twenty (20) in the South Texas area including Corpus Christi and Victoria, thirty-three (33) in the Central Texas, ten (10) in the Bryan/College Station area, twenty-one (21) in East Texas and thirty-one (31) in the Dallas/Fort Worth, Texas area. 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 continuous 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 March 26, 2010, the Company purchased three (3) retail branches of U.S. Bank. The three banking centers acquired by the Company were the Texas locations U.S. Bank acquired from the FDIC on October 30, 2009 when U.S. Bank acquired the nine (9) subsidiary banks of FBOP Corporation. On April 30, 2010, the Company purchased nineteen (19) Texas retail branches of First Bank, and subsequently consolidated four of these branches into nearby existing Company banking centers.

Total assets were $9.61 billion at June 30, 2010 compared with $8.85 billion at December 31, 2009, an increase of $758.4 million or 8.6%. Total loans were $3.42 billion at June 30, 2010 compared with $3.38 billion at December 31, 2009, an increase of $48.3 million or 1.4%. Total deposits were $7.81 billion at June 30, 2010 compared with $7.26 billion December 31, 2009, an increase of $555.4 million or 7.7%. The increase in total assets, loans and deposits is primarily due to the acquisition of the U.S. Bank and First Bank branches. Shareholders’ equity increased $52.9 million or 3.9%, to $1.40 billion at June 30, 2010 compared with $1.35 billion at December 31, 2009.

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, 2009. 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 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 conditions 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 FASB ASC Topic 310, “Receivables,” and allowance allocations determined in accordance with FASB ASC Topic 450, “Contingencies.”

Goodwill and Intangible Assets—Goodwill and intangible assets that have indefinite useful lives are subject to an impairment test at least annually, or more often, if events or circumstances indicate that it is more likely than not that the fair value of Prosperity Bank, the Company’s only reporting unit with assigned goodwill, is below the carrying value of its equity. Goodwill is tested for impairment using a two-step process that begins with an estimation of the fair value of the Company’s reporting unit compared with its carrying value. If the carrying amount exceeds the fair value of the 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. The Company had no intangible assets with indefinite useful lives at June 30, 2010. 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, 2009, management does not believe any of its goodwill is impaired as of June 30, 2010 because the fair value of the Company’s equity exceeded its carrying value. While the Company believes no impairment existed at June 30, 2010 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 FASB ASC Topic 718, Stock Compensation. ASC 718 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. ASC 718 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.

Other-Than-Temporarily Impaired 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 (i) the length of time and the extent to which the fair value has been less than cost, (ii) the financial condition and near-term prospects of the issuer, (iii) whether the market decline was affected by macroeconomic conditions, and (iv) 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. 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 $31.7 million ($0.68 per common share on a diluted basis) for the quarter ended June 30, 2010 compared with $26.5 million ($0.57 per common share on a diluted basis) for the quarter ended June 30, 2009, an increase in net income of $5.2 million or 19.8%. The Company posted returns on average common equity of 9.12% and 8.18%, returns on average assets of 1.34% and 1.20% and efficiency ratios of 46.04% and 48.98% for the quarters ended June 30, 2010 and 2009, 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). Additionally, taxes are not part of this calculation.

For the six months ended June 30, 2010, net income available to common shareholders was $62.7 million ($1.34 per common share on a diluted basis) compared with $52.0 million ($1.13 per common share on a diluted basis) for the same period in 2009, an increase in net income of $10.8 million or 20.7%. The Company posted returns on average common equity of 9.05% and 8.12%, returns on average assets of 1.36% and 1.17% and efficiency ratios of 44.93% and 49.22% for the six months ended June 30, 2010 and 2009, 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 $80.6 million for the quarter ended June 30, 2010 compared with $75.5 million for the quarter ended June 30, 2009, an increase of $5.1 million, or 6.7%. Net interest income increased as a result of an increase in average interest-earning assets to $8.16 billion for the quarter ended June 30, 2010 compared with $7.56 billion for the quarter ended June 30, 2009, an increase of $595.8 million, or 7.9%. The increase in average earning assets was primarily attributable to increases in average securities primarily resulting from the investment of funds received in the purchase of the U.S. Bank and First Bank branches. The increase is net interest income was also due to decreased interest expense resulting from lower deposit pricing.

The net interest margin on a tax equivalent basis decreased to 4.00% for the quarter ended June 30, 2010 compared with 4.04% for the quarter ended June 30, 2009. The average rate paid on interest-bearing liabilities decreased 66 basis points from 1.83% for the quarter ended June 30, 2009 to 1.17% for the quarter ended June 30, 2010. The average yield on earning assets decreased 56 basis points from 5.45% for the quarter ended June 30, 2009 to 4.89% for the quarter ended June 30, 2010. The volume of interest-bearing liabilities increased $489.0 million and the volume of interest-earning assets increased $555.8 million for the same periods.

Net interest income before the provision for credit losses increased $8.8 million, or 5.9%, to $158.4 million for the six months ended June 30, 2010 compared with $149.6 million for the same period in 2009. This increase was mainly attributable to higher average interest-earning assets resulting from an increase in average securities primarily due to the investment of funds received in the U.S. Bank and First Bank branch purchases. The net interest margin on a tax equivalent basis increased to 4.09% compared with 4.01% for the same periods principally due to a 76 basis point decrease in the average rate paid on interest-bearing liabilities from 1.97% for the six months ended June 30, 2009 to 1.21% for the six months ended June 30, 2010 and a 51 basis point decrease in the average yield on earning assets from 5.53% for the six months ended June 30, 2009 to 5.02% for the six months ended June 30, 2010.

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 three and the six month periods ended June 30, 2010 and 2009. 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.

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 $3.3 million provision for credit losses for the quarter ended June 30, 2010 and a $6.9 million provision for the quarter ended June 30, 2009. Net charge-offs were $2.4 million for the quarter ended June 30, 2010 compared with net charge-offs of $3.5 million for the quarter ended June 30, 2009. The Company made a $7.7 million provision for credit losses for the six months ended June 30, 2010 and a $13.0 million provision for the six months ended June 30, 2009. Net charge-offs were $6.8 million for the six months ended June 30, 2010 compared with $7.4 million for the six months ended June 30, 2009.

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 $13.3 million for the three months ended June 30, 2010 compared with $15.1 million for the same period in 2009, a decrease of $1.8 million, or 12.1%. Noninterest income decreased $3.9 million, or 12.9%, to $26.3 million for the six months ended June 30, 2010 compared with $30.2 million for the same period in 2009. Both decreases were primarily due to an increase in losses on sale of ORE and a decrease in insufficient funds charges.

The net loss on sale of ORE was $1.7 million for the three months ended June 30, 2010 compared with a net gain of $415,000 for the three months ended June 30, 2009. The net loss on sale of ORE was $2.0 million for the six months ended June 30, 2010 compared with a net gain of $437,000 for the same period in 2009.

Other noninterest income increased $23,000 or 4.8% to $502,000 for the three months ended June 30, 2010 compared with $479,000 for the same period in 2009. Other noninterest income decreased $687,000 or 38.7% to $1.1 million for the six months ended June 30, 2010 compared with $1.8 million for the same period in 2009. The decrease 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:

Total noninterest income	$	13,296		$	15,133	$	26,274		$	30,150

Noninterest Expense

Noninterest expense totaled $43.0 million for the quarter ended June 30, 2010 compared with $44.3 million for the quarter ended June 30, 2009, a decrease of $1.3 million or 2.8%. Noninterest expense totaled $82.8 million for the six months ended June 30, 2010 compared with $88.3 million for the six months ended June 30, 2009, a decrease of $5.5 million or 6.3%. Both decreases occurred primarily in reduced regulatory assessments and FDIC insurance. The following table presents, for the periods indicated, the major categories of noninterest expense:

(1)	Includes stock based compensation expense of $692,000 and $294,000 for the three months ended June 30, 2010 and 2009, respectively, and $1.5 million and $620,000 for the six months ended June 30, 2010 and 2009, respectively.

Salaries and employee benefit expenses were $22.4 million for the quarter ended June 30, 2010 compared with $20.5 million for the quarter ended June 30, 2009, an increase of $1.9 million, or 9.5%. The increase was principally due to the new associates hired in connection with the U.S. Bank and First Bank branch acquisitions. For the six months ended June 30, 2010, salaries and employee benefit expenses were $43.5 million, an increase of $401,000 or 0.9% compared with $43.1 million for the six months ended June 30, 2009. The number of full-time equivalent (FTE) associates employed by the Company was 1,753 at June 30, 2010, 1,651 at March 31, 2010 and 1,634 at June 30, 2009.

Regulatory assessments and FDIC insurance decreased $3.0 million, or 51.5%, to $2.8 million for the quarter ended June 30, 2010 compared with $5.8 million during the same period in 2009. Regulatory assessments and FDIC insurance decreased $3.3 million, or 38.2%, to $5.4 million for the six months ended June 30, 2010 compared with $8.8 million during the same period in 2009. The decreases in both periods were due to the special assessment of 5 basis points on total assets minus total Tier 1 capital imposed by the FDIC as of June 30, 2009. The special assessment was paid on September 30, 2009.

Income Taxes

Income tax expense increased $2.9 million or 22.3% to $15.8 million for the quarter ended June 30, 2010 compared with $12.9 million for the same period in 2009. For the six months ended June 30, 2010, income tax expense totaled $31.4 million, an increase of $5.0 million or 19.0% compared with $26.4 million for the same period in 2009. The increase was primarily attributable to higher pretax net earnings for the three and six months ended June 30, 2010 compared with the same respective periods in 2009. The effective tax rate for the three months ended June 30, 2010 and 2009 was 33.3% and 32.8%, respectively. The effective tax rate for the six months ended June 30, 2010 and 2009 was 33.4% and 33.7%, 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 June 30, 2010, the allowance for credit losses amounted to $52.7 million or 1.54% of total loans compared with $51.9 million or 1.54% of total loans at December 31, 2009.

Set forth below is an analysis of the allowance for credit losses for the six months ended June 30, 2010 and the year ended December 31, 2009:

Securities

The carrying cost of securities totaled $4.82 billion at June 30, 2010 compared with $4.12 billion at December 31, 2009, an increase of $699.6 million or 17.0%. At June 30, 2010, securities represented 50.1% of total assets compared with 46.5% of total assets at December 31, 2009.

The following table summarizes the amortized cost of securities as of the dates shown (available for sale securities are not adjusted for unrealized gains or losses):


	June 30, 2010		December 31, 2009

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 FASB ASC Topic 320, Investments—Debt and Equity Securities. 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 ASC Topic 325, Investments-Other. The Company currently does not own any securities that are accounted for under ASC Topic 325.

In determining OTTI under ASC Topic 320, management considers many factors, including: (i) the length of time and the extent to which the fair value has been less than cost, (ii) the financial condition and near-term prospects of the issuer, (iii) whether the market decline was affected by macroeconomic conditions, and (iv) 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 OTTI 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 ASC Topic 325 that is specific to purchased beneficial interests that, on the purchase date, were rated below AA. Under the ASC Topic 325 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 applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings shall become the new amortized cost basis of the investment.

Management does not intend to sell any debt securities or more likely than not will not be required to sell any debt securities before their anticipated recovery, at which time the Company will receive full value for the securities. Furthermore, management has the intent to hold the securities classified as available for sale that were in a loss position as of June 30, 2010 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, 2010, 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, 2010:

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. FHLB advances are considered short-term, overnight borrowings. At June 30, 2010, the Company had $140.0 million in FHLB advances and $14.9 million in FHLB long-term notes payable compared with no FHLB advances and $26.1 million in FHLB long-term notes payable at December 31, 2009. FHLB advances are available to the Company under a security and pledge agreement. At June 30, 2010, the Company had total funds of $3.10 billion available under this agreement of which $154.9 million was outstanding. The weighted average interest rate paid on the FHLB notes payable at period end was 5.2%. The maturity dates on the FHLB notes payable range from the years 2011 to 2028 and have interest rates ranging from 3.55% to 6.10%. The highest outstanding balance of FHLB advances during the six months ended June 30, 2010 was $218.0 million compared with $231.0 million for the year ended December 31, 2009. The average rate paid on FHLB advances for the six months ended June 30, 2010 was 0.13%.

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, 2010, the Company had outstanding $462.3 million in commitments to extend credit and $15.1 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, 2010, the Company had cash and cash equivalents of $149.2 million compared with $195.3 million at December 31, 2009, a decrease of $46.1 million. The decrease was primarily due to a decrease in deposits of $312.4 million, purchases of securities of $2.32 billion, premiums paid for acquisitions of $40.0 million and purchases of premises and equipment of $11.5 million, partially offset by proceeds from the maturities and repayments of securities of $1.62 billion, a decrease in loans of $52.7 million, net earnings of $62.7 million, proceeds from the sale of bank premises, equipment and ORE of $21.2 million, net proceeds from short-term debt of $140.0 million, an increase in securities sold under repurchase agreements of $16.7 million and cash received from acquisitions of $724.5 million.

Capital Resources

Total shareholders’ equity was $1.40 billion at June 30, 2010 compared with $1.35 billion at December 31, 2009, an increase of $52.9 million or 3.9%. The increase was due primarily to net earnings of $62.7 million and an increase in unrealized gain on available for sale securities of $1.4 million, partially offset by dividends paid of $14.4 million for the six months ended June 30, 2010.

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 1 risk-based capital and Tier 1 to average assets (leverage) ratios as of June 30, 2010:


Consolidated Capital Ratios:
Total capital (to risk weighted assets)	13.56	%
Tier 1 capital (to risk weighted assets)	12.31	%
Tier 1 capital (to average assets)	6.10	%

As of June 30, 2010, the Bank’s risk-based capital ratios were above the levels required for the Bank to be designated as “well capitalized” by the FDIC. To be designated as “well capitalized”, the minimum ratio requirements for the Bank’s total risk-based capital, Tier 1 risk-based capital, and Tier 1 to average assets (leverage) capital ratios must be 10.0%, 6.0% and 5.0%, respectively. The following table sets forth the Bank’s total risk-based capital, Tier 1 risk-based capital and Tier 1 to average assets (leverage) ratios as of June 30, 2010:


Capital Ratios (Bank Only):
Total capital (to risk weighted assets)	13.30	%
Tier 1 capital (to risk weighted assets)	12.06	%
Tier 1 capital (to average assets)	5.97	%

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 1, 2010 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, 2010 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
