PART I

ITEM 1. BUSINESS

General

Prosperity Bancshares, Inc.®, a Texas
corporation (the Company), was formed in 1983 as a vehicle to acquire the former Allied 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 broad line of financial products and services to small and medium-sized businesses and consumers. As of December 31, 2008, the Bank operated one hundred sixty-eight
(168) full-service banking locations; with fifty-three (53) in the Greater Houston Consolidated Metropolitan Statistical Area (CMSA), twenty-seven (27) in the South Texas area including Corpus Christi and Victoria,
forty-three (43) in the Central Texas area including Austin and Bryan/College Station,, twenty-one (21) 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 Bank intends to consolidate ten (10) of these banking centers, all of which were former Franklin Bank locations, with nearby banking centers in
the first quarter of 2009. 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.

The Companys market consists of the communities served by its banking centers. The diverse nature
of the economies in each local market served by the Company provides the Company with a varied customer base and allows the Company to spread its lending risk throughout a number of different industries including professional service firms and their
principals, manufacturing, tourism, recreation, petrochemicals, farming and ranching. The Companys market areas outside of Houston, Dallas, Corpus Christi and Austin are dominated by either small community banks or branches of large regional
banks. Management believes that the Company, as one of the few mid-sized financial institutions that combines responsive community banking with the sophistication of a regional bank holding company, has a competitive advantage in its market areas
and excellent growth opportunities through acquisitions, new banking center locations and additional business development.

Operating under
a community banking philosophy, the Company seeks to develop broad customer relationships based on service and convenience while maintaining its conservative approach to lending and strong asset quality. The Company has grown through a combination
of internal growth, the acquisition of community banks, branches of banks and the opening of new banking centers. Utilizing a low cost of funds and employing stringent cost controls, the Company has been profitable in every full year of its
existence, including the period of adverse economic conditions in Texas in the late 1980s. From 1988 to 1992, as a sound and profitable institution, the Company took advantage of this economic downturn and acquired the deposits and certain assets of
failed banks in West Columbia, El Campo and Cuero, Texas and two failed banks in Houston, which diversified the Companys franchise and increased its core deposits. The Company opened a full-service banking center in Victoria, Texas in 1993 and
the following year established a banking center in Bay City, Texas. The Company expanded its Bay City presence in 1996 with the acquisition of an additional branch location from Norwest Bank Texas (now Wells Fargo), and in 1997, the Company acquired
the Angleton, Texas branch of Wells Fargo Bank. In 1998, the Company enhanced its West Columbia Banking Center with the purchase of a commercial bank branch located in West Columbia and acquired Union State Bank in East Bernard, Texas.

Recent Market Developments

In recent months, new laws and regulations have been enacted in response to the deterioration in economic conditions, market volatility and related credit and liquidity issues. One such law, the Emergency Economic Stabilization Act of 2008
(EESA) granted the U.S. Treasury the authority to take a range of actions for the purpose of stabilizing and providing liquidity to the U.S. financial markets and included several programs, including the direct purchase by the U.S.
Treasury of equity of healthy financial institutions under the Capital Purchase Program. The Company elected not to participate in the Capital Purchase Program. For additional details about the recent legislative initiatives, please refer to the
section captioned Supervision and RegulationLegislative Initiatives in Part I, Item I of this Annual Report on Form 10-K.

2008 Acquisitions

On January 10, 2008, the Company completed its acquisition of six (6) Houston retail branches from Banco Popular North America. In connection
with the acquisition, the Company assumed approximately $125.0 million in deposits and six (6) banking centers. In the second quarter of 2008, one banking center was closed and consolidated with a nearby Prosperity banking center.

On June 1, 2008, the Company completed its acquisition of 1st Choice Bancorp, Inc and its wholly-owned subsidiary, 1st Choice Bank. 1st Choice
operated two (2) banking offices in Houston, Texas, with one location in South Houston and another in the Heights area. Prosperitys Heights banking center was consolidated with the 1st Choice Heights location, with the resulting banking
center being located in 1st Choices Heights banking office. As of March 31, 2008, 1st Choice had, on a consolidated basis, total assets of $313.9 million, loans of $198.9 million, deposits of $285.1 million and stockholders equity
of $27.5 million. Under the terms of the definitive agreement, Prosperity issued 1,757,752 shares of Prosperity common stock plus approximately $18,758,000 in cash for all outstanding shares of 1st Choice.

On November 7, 2008, the Bank assumed approximately $3.6 billion of deposits and acquired certain assets from the FDIC, acting in its capacity as
receiver for Franklin Bank (the Franklin acquisition or the Franklin Bank acquisition). The FDIC entered into a purchase and assumption agreement with the Bank, which paid a premium of $60.9 million to ensure that all
deposits of Franklin Bank, both insured and uninsured, were transferred to it. Under terms of the purchase and assumption agreement, the Bank acquired certain assets from the FDIC, including approximately $350 million in U.S. Treasury and Agency
Securities and approximately $360 million in performing loans. The remaining net proceeds were predominately invested in mortgage backed securities primarily issued by federal government agencies such as Ginnie Mae, Freddie Mac and Fannie Mae. The
purchase and assumption transaction was accounted for as a business acquisition in accordance with SFAS 141.

The purchase and assumption
agreement also provided the Bank with an option to purchase at fair value any or all of the owned premises of the banking offices of Franklin Bank and to assume the leases of the leased banking offices by providing written notice to the
FDIC within 120 days after November 7, 2008. The Bank intends to purchase twenty-nine (29) of the owned banking offices for an aggregate purchase price of approximately $27.0 million and to assume the leases for six
(6) banking offices. In addition, under the terms of the purchase and assumption agreement, the Bank is required to purchase the furniture, fixtures and equipment at any banking office it purchases
or leases. Accordingly, the Bank intends to purchase approximately $2.0 million in furniture, fixtures and equipment from the FDIC. The Bank expects to complete these purchases in the second quarter of 2009.

While Franklin Bank operated forty-five (45) full service banking offices, the Company expects to continue to operate thirty-five (35) of these
locations upon the completion of the operational integration expected to occur during the first quarter of 2009. The former Franklin Bank locations planned to be closed will be consolidated into nearby Prosperity Bank locations.

Officers and Associates

The Companys directors and officers are important to the Companys success and play a key role in the Companys business development
efforts by actively participating in civic and public service activities in the communities served by the Company.

The Company has
invested heavily in its officers and associates by recruiting talented officers in its market areas and providing them with economic incentive in the form of stock-based compensation and bonuses based on cross-selling performance. The senior
management team has substantial experience in the Houston, Dallas, Austin, Bryan/College Station, East Texas, Corpus Christi and San Antonio markets and the surrounding communities in which the Company has a presence. Each banking center location is
administered by a local president or manager with knowledge of the community and lending expertise in the specific industries found in the community. The Company entrusts its banking center Presidents and Managers with authority and flexibility
within general parameters with respect to product pricing and decision making in order to avoid the bureaucratic structure of larger banks. The Company operates each banking center as a separate profit center, maintaining separate data with respect
to each banking centers 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s local banking centers have no 1-800 telephone numbers. Each banking center has its own listed local business telephone number. Customers are served by a local banker with decision making authority.

As of December 31, 2008, the Company and the Bank had 1,734 full-time equivalent associates, 619 of whom were officers of the Bank. The Company
provides medical and hospitalization insurance to its full-time associates. The Company considers its relations with associates to be excellent. Neither the Company nor the Bank is a party to any collective bargaining agreement.

Banking Activities

The
Company, through the Bank, offers a variety of traditional loan and deposit products to its customers, which consist primarily of consumers and small and medium-sized businesses. The Bank tailors its products to the specific needs of customers in a
given market. At December 31, 2008, the Bank maintained approximately 395,000 separate deposit accounts including certificates of deposit, 42,000 separate loan accounts and 20.9% of the Banks total deposits were noninterest-bearing demand
deposits. For the year ended December 31, 2008, the Companys average cost of funds was 2.08% and the Companys average cost of deposits (excluding all borrowings) was 1.97%.

The Company has been an active real estate lender, with commercial mortgage and 1-4 family residential loans comprising 35.6% and 18.7% of the
Companys total loans as of December 31, 2008, respectively. The Company also offers commercial loans, loans for automobiles and other consumer durables, home equity loans, debit cards, internet banking and other cash management services
and automated telephone banking. By offering certificates of deposit, interest checking accounts, savings accounts and overdraft protection at competitive rates, the Company gives its depositors a full range of traditional deposit products.

##### Table of Contents

The businesses targeted by the Company in its lending efforts are primarily those that require loans in
the $100,000 to $8.0 million range. The Company offers these businesses a broad array of loan products including term loans, lines of credit and loans for working capital, business expansion and the purchase of equipment and machinery, interim
construction loans for builders and owner-occupied commercial real estate loans.

Business Strategies

The Companys main objective is to increase deposits and loans internally, as well as through additional expansion opportunities, while maintaining
efficiency and individualized customer service and maximizing profitability. To achieve this objective, the Company has employed the following strategic goals:

Continue Community Banking Emphasis. The Company intends to continue operating as a community banking organization focused on meeting the specific needs of consumers and small and medium-sized businesses in its
market areas. The Company will continue to provide a high degree of responsiveness combined with a wide variety of banking products and services. The Company staffs its banking centers with experienced bankers with lending expertise in the specific
industries found in the given community, and gives them authority to make certain pricing and credit decisions, avoiding the bureaucratic structure of larger banks.

Expand Market Share Through Internal Growth and a Disciplined Acquisition Strategy. The Company intends to continue seeking opportunities, both inside and outside its existing markets, to expand either by
acquiring existing banks or branches of banks or by establishing new banking centers. All of the Companys acquisitions have been accretive to earnings within 12 months after acquisition date and generally have supplied the Company with
relatively low-cost deposits which have been used to fund the Companys lending and investing activities. However, the Company makes no guarantee that future acquisitions, if any, will be accretive to earnings within any particular time period.
Factors used by the Company to evaluate expansion opportunities include the similarity in management and operating philosophies, whether the acquisition will be accretive to earnings and enhance shareholder value, the ability to achieve economies of
scale to improve the efficiency ratio and the opportunity to enhance the Companys market presence.

Increase Loan Volume and
Diversify Loan Portfolio. While maintaining its conservative approach to lending, the Company has emphasized both new and existing loan products, focusing on growing its commercial mortgage and commercial loan portfolios. During the two-year
period from December 31, 2006 to December 31, 2008, the Companys commercial and industrial loans grew from $281.0 million to $482.5 million, or 71.7%, and represented 12.9% and 13.5% of the total portfolio, respectively. Commercial
mortgages increased from $803.1 million to $1.27 billion, or 57.9%, and represented 36.9% and 35.6% of the total portfolio, respectively, for the same period. In addition, the Company targets professional service firms, including legal and medical
practices, for both loans secured by owner-occupied premises and personal loans to their principals.

Maintain Strong Asset Quality.
The Company continues to maintain the strong asset quality that has been representative of its historical loan portfolio. As the Company diversifies and increases its lending activities and acquires loans in acquisitions, it may face higher risks of
nonpayment and increased risks in the event of economic downturns. The Company intends to continue to employ the strict underwriting guidelines and comprehensive loan review process that have contributed to its low incidence of nonperforming assets
and its minimal charge-offs in relation to its size.

Continue Focus on Efficiency. The Company plans to maintain its 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. For its banking centers, which the Company operates as
independent profit centers, the Company supplies complete support in the areas of loan review, internal audit, compliance and training. Management believes that this centralized infrastructure can accommodate additional growth while enabling the
Company to minimize operational costs through economies of scale.

Enhance Cross-Selling. The Company recognizes that its customer base provides significant
opportunities to cross-sell various products and it seeks to develop broader customer relationships by identifying cross-selling opportunities. The Company uses incentives and friendly competition to encourage cross-selling efforts and increase
cross-selling results among its associates. Officers and associates have access to each customers existing and related account relationships and are better able to inform customers of additional products when customers visit or call the
various banking centers or use their drive-in facilities. In addition, the Company includes product information in monthly statements and other mailings.

Competition

The banking business is highly competitive, and the profitability of the Company
depends principally on its ability to compete in its market areas. The Company competes with other commercial banks, savings banks, savings and loan associations, credit unions, finance companies, mutual funds, insurance companies, brokerage and
investment banking firms, asset-based nonbank lenders and certain other nonfinancial entities, including retail stores which may maintain their own credit programs and certain governmental organizations which may offer more favorable financing than
the Company. The Company believes it has been able to compete effectively with other financial institutions by emphasizing customer service, technology and responsive decision-making with respect to loans, by establishing long-term customer
relationships and building customer loyalty and by providing products and services designed to address the specific needs of its customers.

Supervision and Regulation

The supervision and regulation of bank holding companies and their subsidiaries is intended primarily
for the protection of depositors, the deposit insurance fund of the Federal Deposit Insurance Corporation (FDIC) and the banking system as a whole, and not for the protection of the bank holding company shareholders or creditors. The
banking agencies have broad enforcement power over bank holding companies and banks including the power to impose substantial fines and other penalties for violations of laws and regulations.

The following description summarizes some of the laws to which the Company and the Bank are subject. References in this annual report on Form 10-K to
applicable statutes and regulations are brief summaries thereof, do not purport to be complete, and are qualified in their entirety by reference to such statutes and regulations.

The Company

The Company is a financial holding company pursuant to the Gramm-Leach-Bliley Act
and a bank holding company registered under the Bank Holding Company Act of 1956, as amended (BHCA). Accordingly, the Company is subject to supervision, regulation and examination by the Board of Governors of the Federal Reserve System
(Federal Reserve Board). The Gramm-Leach-Bliley Act, the BHCA and other federal laws subject financial and bank holding companies to particular restrictions on the types of activities in which they may engage, and to a range of
supervisory requirements and activities, including regulatory enforcement actions for violations of laws and regulations.

Regulatory
Restrictions on Dividends; Source of Strength. It is the policy of the Federal Reserve Board that bank holding companies should pay cash dividends on common stock only out of income available over the past year and only if prospective earnings
retention is consistent with the organizations expected future needs and financial condition. The policy provides that bank holding companies should not maintain a level of cash dividends that undermines the bank holding companys ability
to serve as a source of strength to its banking subsidiaries.

Under Federal Reserve Board policy, a bank holding company is expected to
act as a source of financial strength to each of its banking subsidiaries and commit resources to their support. Such support may be required at times when, absent this Federal Reserve Board policy, a holding company may not be inclined to provide
it. As discussed below, a bank holding company, in certain circumstances, could be required to guarantee the capital plan of an undercapitalized banking subsidiary.

##### Table of Contents

In the event of a bank holding companys bankruptcy under Chapter 11 of the U.S. Bankruptcy Code,
the trustee will be deemed to have assumed and is required to cure immediately any deficit under any commitment by the debtor holding company to any of the federal banking agencies to maintain the capital of an insured depository institution. Any
claim for breach of such obligation will generally have priority over most other unsecured claims.

Scope of Permissible Activities.
Under the BHCA, bank holding companies generally may not acquire a direct or indirect interest in or control of more than 5% of the voting shares of any company that is not a bank or bank holding company or from engaging in activities other than
those of banking, managing or controlling banks or furnishing services to or performing services for its subsidiaries, except that it may engage in, directly or indirectly, certain activities that the Federal Reserve Board has determined to be
closely related to banking or managing and controlling banks as to be a proper incident thereto. In approving acquisitions or the addition of activities, the Federal Reserve considers, among other things, whether the acquisition or the additional
activities can reasonably be expected to produce benefits to the public, such as greater convenience, increased competition, or gains in efficiency, that outweigh such possible adverse effects as undue concentration of resources, decreased or unfair
competition, conflicts of interest or unsound banking practices.

Notwithstanding the foregoing, the Gramm-Leach-Bliley Act, effective
March 11, 2000, eliminated the barriers to affiliations among banks, securities firms, insurance companies and other financial service providers and permits bank holding companies to become financial holding companies and thereby affiliate with
securities firms and insurance companies and engage in other activities that are financial in nature. The Gramm-Leach- Bliley Act defines financial in nature to include securities underwriting, dealing and market making; sponsoring
mutual funds and investment companies; insurance underwriting and agency; merchant banking activities; and activities that the Federal Reserve Board has determined to be closely related to banking. No regulatory approval will be required for a
financial holding company to acquire a company, other than a bank or savings association, engaged in activities that are financial in nature or incidental to activities that are financial in nature, as determined by the Federal Reserve Board.

Under the Gramm-Leach-Bliley Act, a bank holding company may become a financial holding company by filing a declaration with the Federal
Reserve Board if each of its subsidiary banks is well capitalized under the Federal Deposit Insurance Corporation Improvement Act prompt-corrective-action provisions, is well managed, and has at least a satisfactory rating under the Community
Reinvestment Act of 1977. The Company became a financial holding company on April 18, 2000.

While the Federal Reserve Board is the
umbrella regulator for financial holding companies and has the power to examine banking organizations engaged in new activities, regulation and supervision of activities which are financial in nature or determined to be incidental to
such financial activities will be handled along functional lines. Accordingly, activities of subsidiaries of a financial holding company will be regulated by the agency or authorities with the most experience regulating that activity as it is
conducted in a financial holding company.

Safe and Sound Banking Practices. Bank holding companies are not permitted to engage in
unsafe and unsound banking practices. The Federal Reserve Boards Regulation Y, for example, generally requires a holding company to give the Federal Reserve Board prior notice of any redemption or repurchase of its own equity securities, if
the consideration to be paid, together with the consideration paid for any repurchases or redemptions in the preceding year, is equal to 10% or more of the companys consolidated net worth. The Federal Reserve Board may oppose the transaction
if it believes that the transaction would constitute an unsafe or unsound practice or would violate any law or regulation. Depending upon the circumstances, the Federal Reserve Board could take the position that paying a dividend would constitute an
unsafe or unsound banking practice.

The Federal Reserve Board has broad authority to prohibit activities of bank holding companies and
their nonbanking subsidiaries which represent unsafe and unsound banking practices or which constitute violations of laws or regulations, and can assess civil money penalties for certain activities conducted on a knowing and

reckless basis, if those activities caused a substantial loss to a depository institution. The penalties can be as high as $1.0 million for each day the
activity continues.

Anti-Tying Restrictions. Bank holding companies and their affiliates are prohibited from tying the provision of
certain services, such as extensions of credit, to other services offered by a holding company or its affiliates.

Capital Adequacy
Requirements. The Federal Reserve Board has adopted a system using risk-based capital guidelines to evaluate the capital adequacy of bank holding companies. Under the guidelines, specific categories of assets are assigned different risk weights,
based generally on the perceived credit risk of the asset. These risk weights are multiplied by corresponding asset balances to determine a risk-weighted asset base. The guidelines require a minimum ratio of total capital to total
tangible risk-weighted assets of 8.0% (of which at least 4.0% is required to consist of Tier 1 capital elements). Total capital is the sum of Tier 1 and Tier 2 capital. As of December 31, 2008, the Companys ratio of Tier 1 capital to
total tangible risk-weighted assets was 10.27% and its ratio of total capital to total tangible risk-weighted assets was 11.17%. Tangible risk-weighted assets are calculated as total risk-weighted assets less intangible assets such as goodwill and
core deposit intangibles.

In addition to the risk-based capital guidelines, the Federal Reserve Board uses a leverage ratio as an
additional tool to evaluate the capital adequacy of bank holding companies. The leverage ratio is a companys Tier 1 capital divided by its average total tangible consolidated assets. Certain highly rated bank holding companies may maintain a
minimum leverage ratio of 3.0%, but other bank holding companies are required to maintain a leverage ratio of 4.0%. As of December 31, 2008, the Companys leverage ratio was 5.68%.

The federal banking agencies risk-based and leverage ratios are minimum supervisory ratios generally applicable to banking organizations that meet
certain specified criteria, assuming that they have the highest regulatory rating. Banking organizations not meeting these criteria are expected to operate with capital positions well above the minimum ratios. The federal bank regulatory agencies
may set capital requirements for a particular banking organization that are higher than the minimum ratios when circumstances warrant. Federal Reserve Board guidelines also provide that banking organizations experiencing internal growth or making
acquisitions will be expected to maintain strong capital positions substantially above the minimum supervisory levels, without significant reliance on intangible assets.

Imposition of Liability for Undercapitalized Subsidiaries. Bank regulators are required to take prompt corrective action to resolve problems associated with insured depository institutions whose
capital declines below certain levels. In the event an institution becomes undercapitalized, it must submit a capital restoration plan. The capital restoration plan will not be accepted by the regulators unless each company having
control of the undercapitalized institution guarantees the subsidiarys compliance with the capital restoration plan up to a certain specified amount. Any such guarantee from a depository institutions holding company is entitled to a
priority of payment in bankruptcy.

The aggregate liability of the holding company of an undercapitalized bank is limited to the lesser of
5% of the institutions assets at the time it became undercapitalized or the amount necessary to cause the institution to be adequately capitalized. The bank regulators have greater power in situations where an institution becomes
significantly or critically undercapitalized or fails to submit a capital restoration plan. For example, a bank holding company controlling such an institution can be required to obtain prior Federal Reserve Board approval of
proposed dividends, or might be required to consent to a consolidation or to divest the troubled institution or other affiliates.

Acquisitions by Bank Holding Companies. The BHCA requires every bank holding company to obtain the prior approval of the Federal Reserve Board before it may acquire all or substantially all of the assets of any bank, or ownership or
control of any voting shares of any bank, if after such acquisition it would own or control, directly or indirectly, more than 5% of the voting shares of such bank. In approving bank acquisitions by bank holding companies, the Federal Reserve Board
is required to consider, among other things, the financial and managerial resources and future prospects of the bank holding company and the banks concerned, the convenience and needs of the communities to be served, and various competitive factors.

##### Table of Contents

Control Acquisitions. The Change in Bank Control Act (CBCA) prohibits a person or
group of persons from acquiring control of a bank holding company unless the Federal Reserve Board has been notified and has not objected to the transaction. Under a rebuttable presumption established by the Federal Reserve Board, the
acquisition of 10% or more of a class of voting stock of a bank holding company with a class of securities registered under Section 12 of the Exchange Act, such as the Company, would, under the circumstances set forth in the presumption,
constitute acquisition of control of the Company.

In addition, the CBCA prohibits any entity from acquiring 25% (5% in the case of an
acquiror that is a bank holding company) or more of a bank holding companys or banks voting securities, or otherwise obtaining control or a controlling influence over a bank holding company or bank without the approval of the Federal
Reserve Board. In most circumstances, an entity that owns 25% or more of the voting securities of a banking organization owns enough of the capital resources to have a controlling influence over such banking organization for purposes of the CBCA. On
September 22, 2008, the Federal Reserve Board issued a policy statement on equity investments in bank holding companies and banks, which allows the Federal Reserve Board to generally be able to conclude that an entitys investment is not
controlling if the entity does not own in excess of 15% of the voting power and 33% of the total equity of the bank holding company or bank. Depending on the nature of the overall investment and the capital structure of the banking
organization, the Federal Reserve Board will permit, based on the policy statement, noncontrolling investments in the form of voting and nonvoting shares that represent in the aggregate (i) less than one-third of the total equity of the banking
organization (and less than one-third of any class of voting securities, assuming conversion of all convertible nonvoting securities held by the entity) and (ii) less than 15% of any class of voting securities of the banking organization.

The Bank

The Bank is a
Texas-chartered banking association, the deposits of which are insured by the Deposit Insurance Fund (DIF) of the FDIC. The Bank is not a member of the Federal Reserve System; therefore, the Bank is subject to supervision and regulation
by the FDIC and the Texas Banking Department. Such supervision and regulation subject the Bank to special restrictions, requirements, potential enforcement actions and periodic examination by the FDIC and the Texas Banking Department. Because the
Federal Reserve Board regulates the bank holding company parent of the Bank, the Federal Reserve Board also has supervisory authority which directly affects the Bank.

Equivalence to National Bank Powers. The Texas Constitution, as amended in 1986, provides that a Texas-chartered bank has the same rights and privileges that are or may be granted to national banks domiciled in
Texas. To the extent that the Texas laws and regulations may have allowed state-chartered banks to engage in a broader range of activities than national banks, the Federal Deposit Insurance Corporation Improvement Act of 1991 (FDICIA)
has operated to limit this authority. FDICIA provides that no state bank or subsidiary thereof may engage as principal in any activity not permitted for national banks, unless the institution complies with applicable capital requirements and the
FDIC determines that the activity poses no significant risk to the insurance fund. In general, statutory restrictions on the activities of banks are aimed at protecting the safety and soundness of depository institutions.

Financial Modernization. Under the Gramm-Leach-Bliley Act, a national bank may establish a financial subsidiary and engage, subject to limitations
on investment, in activities that are financial in nature, other than insurance underwriting as principal, insurance company portfolio investment, real estate development, real estate investment, annuity issuance and merchant banking activities. To
do so, a bank must be well capitalized, well managed and have a Community Reinvestment Act (CRA) rating of satisfactory or better. Subsidiary banks of a financial holding company or national banks with financial subsidiaries must remain
well capitalized and well managed in order to continue to engage in activities that are financial in nature without regulatory actions or restrictions, which could include divestiture of the financial in nature subsidiary or subsidiaries. In
addition, a financial holding company or a bank may not acquire a company that is engaged in activities that are financial in nature unless each of the subsidiary banks of the financial holding company or the bank has a CRA rating of satisfactory of
better.

##### Table of Contents

Although the powers of state chartered banks are not specifically addressed in the Gramm-Leach-Bliley
Act, Texas-chartered banks such as the Bank, will have the same if not greater powers as national banks through the parity provision contained in the Texas Constitution.

Branching. Texas law provides that a Texas-chartered bank can establish a branch anywhere in Texas provided that the branch is approved in advance by the Texas Banking Department. The branch must also be
approved by the FDIC, which considers a number of factors, including financial history, capital adequacy, earnings prospects, character of management, needs of the community and consistency with corporate powers.

Restrictions on Transactions with Affiliates and Insiders. Transactions between the Bank and its nonbanking affiliates, including the Company, are
subject to Section 23A of the Federal Reserve Act. In general, Section 23A imposes limits on the amount of such transactions, and also requires certain levels of collateral for loans to affiliated parties. It also limits the amount of
advances to third parties which are collateralized by the securities or obligations of the Company or its subsidiaries.

Affiliate
transactions are also subject to Section 23B of the Federal Reserve Act which generally requires that certain transactions between the Bank and its affiliates be on terms substantially the same, or at least as favorable to the Bank, as those
prevailing at the time for comparable transactions with or involving other nonaffiliated persons. The Federal Reserve has also issued Regulation W which codifies prior regulations under Sections 23A and 23B of the Federal Reserve Act and
interpretive guidance with respect to affiliate transactions.

The restrictions on loans to directors, executive officers, principal
shareholders and their related interests (collectively referred to herein as insiders) contained in the Federal Reserve Act and Regulation O apply to all insured institutions and their subsidiaries and holding companies. These
restrictions include limits on loans to one borrower and conditions that must be met before such a loan can be made. There is also an aggregate limitation on all loans to insiders and their related interests. These loans cannot exceed the
institutions total unimpaired capital and surplus, and the FDIC may determine that a lesser amount is appropriate. Insiders are subject to enforcement actions for knowingly accepting loans in violation of applicable restrictions.

Restrictions on Distribution of Subsidiary Bank Dividends and Assets. Dividends paid by the Bank have provided a substantial part of the
Companys operating funds and for the foreseeable future it is anticipated that dividends paid by the Bank to the Company will continue to be the Companys principal source of operating funds. Capital adequacy requirements serve to limit
the amount of dividends that may be paid by the Bank. Under federal law, the Bank cannot pay a dividend if, after paying the dividend, the Bank will be undercapitalized. The FDIC may declare a dividend payment to be unsafe and unsound
even though the Bank would continue to meet its capital requirements after the dividend. Because the Company is a legal entity separate and distinct from its subsidiaries, its right to participate in the distribution of assets of any subsidiary upon
the subsidiarys liquidation or reorganization will be subject to the prior claims of the subsidiarys creditors. In the event of a liquidation or other resolution of an insured depository institution, the claims of depositors and other
general or subordinated creditors are entitled to a priority of payment over the claims of holders of any obligation of the institution to its shareholders, including any depository institution holding company (such as the Company) or any
shareholder or creditor thereof.

Examinations. The FDIC periodically examines and evaluates insured banks. Based on such an
evaluation, the FDIC may revalue the assets of the institution and require that it establish specific reserves to compensate for the difference between the FDIC-determined value and the book value of such assets. The Texas Banking Department also
conducts examinations of state banks but may accept the results of a federal examination in lieu of conducting an independent examination. In addition, the FDIC and Texas Banking Department may elect to conduct a joint examination.

Audit Reports. Insured institutions with total assets of $500 million or more must submit annual audit reports prepared by independent auditors to
federal and state regulators. In some instances, the audit report of the



10



---

##### Table of Contents

institutions holding company can be used to satisfy this requirement. Auditors must receive examination reports, supervisory agreements and reports of
enforcement actions. For institutions with total assets of $1 billion or more, financial statements prepared in accordance with generally accepted accounting principles, managements certifications concerning responsibility for the financial
statements, internal controls and compliance with legal requirements designated by the FDIC, and an attestation by the auditor regarding the statements of management relating to the internal controls must be submitted. For institutions with total
assets of more than $3 billion, independent auditors may be required to review quarterly financial statements. FDICIA requires that independent audit committees be formed, consisting of outside directors only. The committees of such institutions
must include members with experience in banking or financial management, must have access to outside counsel, and must not include representatives of large customers.

Capital Adequacy Requirements. The FDIC has adopted regulations establishing minimum requirements for the capital adequacy of insured institutions. The FDIC may establish higher minimum requirements if, for
example, a bank has previously received special attention or has a high susceptibility to interest rate risk.

The FDICs risk-based
capital guidelines generally require state banks to have a minimum ratio of Tier 1 capital to total tangible risk-weighted assets of 4.0% and a ratio of total capital to total tangible risk-weighted assets of 8.0%. The capital categories have the
same definitions for the Bank as for the Company. As of December 31, 2008, the Banks ratio of Tier 1 capital to total tangible risk-weighted assets was 10.00% and its ratio of total capital to total tangible risk-weighted assets was
10.91%.

The FDICs leverage guidelines require state banks to maintain Tier 1 capital of no less than 4.0% of average total tangible
assets, except in the case of certain highly rated banks for which the requirement is 3.0% of average total assets. The Texas Banking Department has issued a policy which generally requires state chartered banks to maintain a leverage ratio (defined
in accordance with federal capital guidelines) of 5.0%. As of December 31, 2008, the Banks ratio of Tier 1 capital to average total assets (leverage ratio) was 5.48%.

Corrective Measures for Capital Deficiencies. The federal banking regulators are required to take prompt corrective action with
respect to capital-deficient institutions. Agency regulations define, for each capital category, the levels at which institutions are well-capitalized, adequately capitalized, under capitalized,
significantly under capitalized and critically under capitalized. A well-capitalized bank has a total risk-based capital ratio of 10.0% or higher; a Tier 1 risk-based capital ratio of 6.0% or higher; a leverage
ratio of 5.0% or higher; and is not subject to any written agreement, order or directive requiring it to maintain a specific capital level for any capital measure. An adequately capitalized bank has a total risk-based capital ratio of
8.0% or higher; a Tier 1 risk-based capital ratio of 4.0% or higher; a leverage ratio of 4.0% or higher (3.0% or higher if the bank was rated a composite 1 in its most recent examination report and is not experiencing significant growth); and does
not meet the criteria for a well capitalized bank. A bank is under capitalized if it fails to meet any one of the ratios required to be adequately capitalized. The Bank is classified as well-capitalized for purposes of the
FDICs prompt corrective action regulations.

In addition to requiring undercapitalized institutions to submit a capital restoration
plan, agency regulations contain broad restrictions on certain activities of undercapitalized institutions including asset growth, acquisitions, branch establishment and expansion into new lines of business. With certain exceptions, an insured
depository institution is prohibited from making capital distributions, including dividends, and is prohibited from paying management fees to control persons if the institution would be undercapitalized after any such distribution or payment.

As an institutions capital decreases, the FDICs enforcement powers become more severe. A significantly undercapitalized
institution is subject to mandated capital raising activities, restrictions on interest rates paid and transactions with affiliates, removal of management and other restrictions. The FDIC has only very limited discretion in dealing with a critically
undercapitalized institution and is virtually required to appoint a receiver or conservator.

##### Table of Contents

Banks with risk-based capital and leverage ratios below the required minimums may also be subject to
certain administrative actions, including the termination of deposit insurance upon notice and hearing, or a temporary suspension of insurance without a hearing in the event the institution has no tangible capital.

Deposit Insurance Assessments. The Bank must pay assessments to the FDIC for deposit insurance protection. The FDIC maintains the DIF by
designating a reserve ratio between a range of 1.15% to 1.50%. If the reserve ratio falls below 1.15%, the FDIC must adopt a restoration plan that provides that the DIF will return to 1.15% generally within 5 years. If the reserve ratio exceeds
1.35%, the FDIC must generally dividend to DIF members half of the amount above the amount necessary to maintain the DIF at 1.35%. The FDIC declares a 50% dividend when the reserve ratio reaches 1.35% and a 100% dividend when the reserve ratio
reaches above 1.50%. The designated reserve ratio is currently set at 1.25%. The FDIC has the discretion to price deposit insurance according to the risk for all insured institutions regardless of the level of the reserve ratio.

The DIF reserve ratio is maintained by assessing depository institutions an insurance premium based upon statutory factors that include the balance of
insured deposits as well as the degree of risk the institution poses to the insurance fund. Under a risk-based assessment system required by the FDICIA, FDIC-insured depository institutions pay quarterly insurance premiums at rates based on their
risk classification. Institutions assigned to higher-risk classifications (that is, institutions that pose a greater risk of loss to their respective deposit insurance funds) pay assessments at higher rates than institutions that pose a lower risk.
An institutions risk classification is assigned based on its capital levels and the level of supervisory concern the institution poses to regulators. An institutions risk assignment includes assignment to Risk Category I, II, III, or IV,
and, within Risk Category I, assignment to an assessment rate or rates.

On January 1, 2009, the FDIC increased the DIF assessment
rates as part of the FDICs DIF restoration plan. As a result, initial base assessment rates currently range from 12 to 14 basis points for Risk Category I institutions, 17 basis points for Risk Category II institutions, 35 basis points for
Risk Category III institutions, and 50 basis points for Risk Category IV institutions. On February 27, 2009, the Board of Directors of the FDIC issued final rules to amend the restoration plan for the DIF, change the risk-based assessment system and
set assessment rates to begin in the second quarter of 2009. Beginning April 1, 2009, total base assessment rates will range from 7 to 24 basis points for Risk Category I institutions, 17 to 43 basis points for Risk Category II institutions, 27 to
58 basis points for Risk Category III institutions, and 40 to 77.5 basis points for Risk Category IV institutions. Institutions with $1 billion or more in assets have its assessment base determined using average daily balances, as opposed to
utilizing quarter-end balances. Institutions with less than $1 billion in assets have the option of continuing to use quarter-end balances to determine their assessment bases. Assessments are paid quarterly by all institutions and are based upon the
assessment base that an institution reports at the end of that quarter. Risk assessments remain in effect for future assessment periods until changed by the FDIC.

Also, on February 27, 2009, the FDIC issued an interim rule for a special assessment of 20 basis points, with the possibility of an additional 10 basis points, to restore the DIF to an acceptable level. Following the
comment period and assuming the interim rule becomes final, the special assessment will be made on June 30, 2009 and will be collected September 30, 2009. This assessment will be in addition to the new assessment rates which become effective April
1, 2009.

Brokered Deposit Restrictions. Adequately capitalized institutions cannot accept, renew or roll over brokered deposits
except with a waiver from the FDIC, and are subject to restrictions on the interest rates that can be paid on any deposits. Undercapitalized institutions may not accept, renew, or roll over brokered deposits.

Cross-Guarantee Provisions. The Financial Institutions Reform, Recovery and Enforcement Act of 1989 (FIRREA) contains a
cross-guarantee provision which generally makes commonly controlled insured depository institutions liable to the FDIC for any losses incurred in connection with the failure of a commonly controlled depository institution.

Community Reinvestment Act. The CRA and the regulations issued thereunder are intended to encourage banks to help meet the credit needs of their
service area, including low and moderate income neighborhoods,

##### Table of Contents

consistent with the safe and sound operations of the banks. These regulations also provide for regulatory assessment of a banks record in meeting the
needs of its service area when considering applications to establish branches, merger applications and applications to acquire the assets and assume the liabilities of another bank. FIRREA requires federal banking agencies to make public a rating of
a banks performance under the CRA. In the case of a bank holding company, the CRA performance record of the banks involved in the transaction are reviewed in connection with the filing of an application to acquire ownership or control of
shares or assets of a bank or to merge with any other bank holding company. An unsatisfactory record can substantially delay or block the transaction.

Consumer Laws and Regulations. In addition to the laws and regulations discussed herein, the Bank is also subject to certain consumer laws and regulations that are designed to protect consumers in transactions
with banks. While the list set forth herein is not exhaustive, these laws and regulations include the Truth in Lending Act, the Truth in Savings Act, the Electronic Funds Transfer Act, the Expedited Funds Availability Act, the Equal Credit
Opportunity Act, and the Fair Housing Act, among others. These laws and regulations mandate certain disclosure requirements and regulate the manner in which financial institutions must deal with customers when taking deposits or making loans to such
customers. The Bank must comply with the applicable provisions of these consumer protection laws and regulations as part of their ongoing customer relations.

Anti-Money Laundering and Anti-Terrorism Legislation. Congress enacted the Bank Secrecy Act of 1970 (BSA) to require financial institutions, including the Company and the Bank, to maintain certain
records and to report certain transactions to prevent such institutions from being used to hide money derived from criminal activity and tax evasion. The BSA establishes, among other things, (1) record keeping requirements to assist government
enforcement agencies in tracing financial transactions and flow of funds; (2) reporting requirements for Suspicious Activity Reports and Currency Transaction Reports to assist government enforcement agencies in detecting patterns of criminal
activity; (3) enforcement provisions authorizing criminal and civil penalties for illegal activities and violations of the BSA and its implementing regulations; and (4) safe harbor provisions that protect financial institutions from civil
liability for their cooperative efforts.

Title III of the Uniting and Strengthening America by Providing Appropriate Tools Required to
Intercept and Obstruct Terrorism Act of 2001 (Patriot Act) enacted in October 2001 amended the BSA and incorporates anti-terrorist financing provisions into the requirements of the BSA and its implementing regulations. Among other
things, the Patriot Act requires all financial institutions, including the Company and the Bank, to institute and maintain a risk-based anti-money laundering compliance program that (i) includes a customer identification program,
(ii) provides for information sharing with law enforcement and between certain financial institutions by means of an exemption from the privacy provisions of the Gramm-Leach-Bliley Act, (iii) prohibits U.S. banks and broker-dealers from
maintaining accounts with foreign shell banks, (iv) establishes due diligence and enhanced due diligence requirements for certain foreign correspondent banking and foreign private banking accounts and (v) imposes additional
record keeping requirements for certain correspondent banking arrangements. The Patriot Act also grants broad authority to the Secretary of the Treasury to take actions to combat money laundering, and federal bank regulators are required to evaluate
the effectiveness of an applicant in combating money laundering in determining whether to approve any application submitted by a financial institution. The Company and the Bank have adopted policies, procedures and controls designed to comply with
the BSA and the Patriot Act.

The Department of the Treasurys Office of Foreign Asset Control (OFAC) administers and
enforces economic and trade sanctions against targeted foreign countries, entities and individuals based on U.S. foreign policy and national security goals. As a result, financial institutions, including the Company and the Bank, must scrutinize
transactions to ensure that they do not represent obligations of, or ownership interests in, entities owned or controlled by sanctioned targets. In addition, the Company and the Bank restrict transactions with certain targeted countries except as
permitted by OFAC.

Privacy. In addition to expanding the activities in which banks and bank holding companies may engage, the
Gramm-Leach-Bliley Act also imposed new requirements on financial institutions with respect to customer



13



---

##### Table of Contents

privacy. The Gramm-Leach-Bliley Act generally prohibits disclosure of customer information to non-affiliated third parties unless the customer has been given
the opportunity to object and has not objected to such disclosure. Financial institutions are further required to disclose their privacy policies to customers annually. Financial institutions, however, will be required to comply with state law if it
is more protective of customer privacy than the Gramm-Leach-Bliley Act.

Legislative Initiatives

In light of current conditions and the market outlook for continuing weak economic conditions, regulators have increased their focus on the regulation of
financial institutions. A number of government initiatives designed to respond to the current conditions have been introduced recently and proposals for legislation that could substantially intensify the regulation of financial institutions are
expected to be introduced in Congress and state legislatures. Such initiatives may change banking statutes and the operating environment of the Company and its banking subsidiaries in substantial and unpredictable ways. The Company cannot determine
the ultimate effect that any potential legislation, if enacted, or implementing regulations with respect thereto, would have, upon the financial condition or results of operations of the Company or its subsidiaries. A change in statutes, regulations
or regulatory policies applicable to the Company or any of its subsidiaries could have a material effect on the financial condition, results of operations or business of the Company and its subsidiaries.

U.S. Treasury Capital Purchase Program. On October 3, 2008, the Emergency Economic Stabilization Act of 2008 (EESA) (initially
introduced as the Troubled Asset Relief Program or TARP) was enacted. TARP gave the U.S. Department of the Treasury (U.S. Treasury) authority to deploy up to $700 billion into the financial system with an objective of
improving liquidity in capital markets. On October 14, 2008, the U.S. Treasury announced the Capital Purchase Program (CPP), which provides for direct equity investment of perpetual preferred stock by the U.S. Treasury in qualified
financial institutions. The program is voluntary and requires an institution to comply with a number of restrictions and provisions, including limits on executive compensation, stock redemptions and declaration of dividends. The CPP provides for the
purchase by the U.S. Treasury of perpetual senior preferred stock in an aggregate amount ranging from 1% to 3% of a participants risk-weighted assets. The senior preferred stock will pay cumulative dividends at a rate of 5% per year, until the
fifth anniversary of the U.S. Treasury investment, and at a rate of 9% per year thereafter. The CPP also requires a participant to issue to the U.S. Treasury warrants to purchase common stock equal to 15% of the capital invested by the U.S.
Treasury. The Company elected not to participate in the CPP.

FDIC Temporary Liquidity Guarantee Program. On November 21,
2008, the Board of Directors of the FDIC adopted a final rule relating to the Temporary Liquidity Guarantee Program (TLGP) announced by the FDIC on October 14, 2008 to prevent systemic risk, promote financial stability by preserving
confidence in the banking system and encourage liquidity in order to ease lending to creditworthy businesses and consumers. The TLGP applies to, among others, all U.S. depository institutions insured by the FDIC and all U.S. bank holding companies,
unless they have opted out. The Company and the Bank did not opt out and have chosen to participate in the TLGP. Under the TLGP, specific categories of newly issued senior unsecured debt issued by the Company or the Bank on or before June 30, 2009
would be guaranteed by the FDIC until June 30, 2012. Under the transaction account guarantee component of the TLGP, all non-interest bearing transaction deposit accounts maintained at the Bank are insured in full by the FDIC until December 31, 2009,
regardless of the standard maximum deposit insurance amounts. Coverage under the TLGP is available to eligible financial institutions at a cost of 50 to 100 basis points per annum, depending on the initial maturity of the senior unsecured debt and
10 basis points per annum for deposit insurance coverage on non-interest bearing transaction account deposits on balances above $250,000.

Comprehensive Financial Stability Plan of 2009. On February 10, 2009, U.S. Treasury Secretary Timothy Geithner announced a new comprehensive financial stability plan (Financial Stability Plan), which builds upon existing
programs and earmarks the second $350 billion of unused funds originally authorized under the EESA.

##### Table of Contents

The major elements of the Financial Stability Plan include: (i) a capital assistance program that will
invest in convertible preferred stock of certain qualifying institutions, (ii) a consumer and business lending initiative to fund new consumer loans, small business loans and commercial mortgage asset-backed securities issuances, (iii) a new
public-private investment fund that will leverage public and private capital with public financing to purchase up to $500 billion to $1 trillion of legacy toxic assets from financial institutions, and (iv) assistance for homeowners by
providing up to $75 billion to reduce mortgage payments and interest rates and establishing loan modification guidelines for government and private programs.

Institutions receiving assistance under the Financial Stability Plan going forward will be subject to higher transparency and accountability standards, including restrictions on dividends, acquisitions and executive
compensation and additional disclosure requirements. The Company cannot predict at this time the effect that the Financial Stability Plan may have on its business, financial condition or results of operations.

American Recovery and Reinvestment Act of 2009. On February 17, 2009, the American Recovery and Reinvestment Act of 2009 (ARRA)
was signed into law. The ARRA contains provisions that will affect institutions that received or will receive financial assistance from the U.S. Treasury under the Capital Purchase Program. The Company elected not to participate in the Capital
Purchase Program.

Enforcement Powers of Federal and State Banking Agencies

The federal banking agencies have broad enforcement powers, including the power to terminate deposit insurance, impose substantial fines and other civil
and criminal penalties, and appoint a conservator or receiver. Failure to comply with applicable laws, regulations, and supervisory agreements could subject the Company or the Bank and their subsidiaries, as well as officers, directors, and other
institution-affiliated parties of these organizations, to administrative sanctions and potentially substantial civil money penalties. In addition to the grounds discussed above under The BankCorrective Measures for Capital
Deficiencies, the appropriate federal banking agency may appoint the FDIC as conservator or receiver for a banking institution (or the FDIC may appoint itself, under certain circumstances) if any one or more of a number of circumstances exist,
including, without limitation, the fact that the banking institution is undercapitalized and has no reasonable prospect of becoming adequately capitalized; fails to become adequately capitalized when required to do so; fails to submit a timely and
acceptable capital restoration plan; or materially fails to implement an accepted capital restoration plan. The Texas Department of Banking also has broad enforcement powers over the Bank, including the power to impose orders, remove officers and
directors, impose fines and appoint supervisors and conservators.

Effect on Economic Environment

The policies of regulatory authorities, including the monetary policy of the Federal Reserve Board, have a significant effect on the operating results of
bank holding companies and their subsidiaries. Among the means available to the Federal Reserve Board to affect the money supply are open market operations in U.S. government securities, changes in the discount rate on member bank borrowings, and
changes in reserve requirements against member bank deposits. These means are used in varying combinations to influence overall growth and distribution of bank loans, investments and deposits, and their use may affect interest rates charged on loans
or paid for deposits.

Federal Reserve Board monetary policies have materially affected the operating results of commercial banks in the
past and are expected to continue to do so in the future. The nature of future monetary policies and the effect of such policies on the business and earnings of the Company and its subsidiaries cannot be predicted.

ITEM 1A. RISK FACTORS

An investment in the Companys Common Stock involves risks. The following is a description of the material risks and uncertainties that the Company believes affect its business and an investment in the Common

Stock. Additional risks and uncertainties that the Company is unaware of, or that it currently deems immaterial,



15

##### Table of Contents

also may become important factors that affect the Company and its business. If any of the risks described in this annual report on Form 10-K were to occur,
the Companys financial condition, results of operations and cash flows could be materially and adversely affected. If this were to happen, the value of the Common Stock could decline significantly and you could lose all or part of your
investment.

Risks Associated with the Companys Business

If the Company is not able to continue its historical levels of growth, it may not be able to maintain its historical earnings trends.

To achieve its past levels of growth, the Company has initiated internal growth programs and completed a number of acquisitions. The Company may not be able to sustain its historical rate of growth or may not be able
to grow at all. In addition, the Company may not be able to obtain the financing necessary to fund additional growth and may not be able to find suitable candidates for acquisition. Various factors, such as economic conditions and competition, may
impede or prohibit the opening of new banking centers. Further, the Company may be unable to attract and retain experienced bankers, which could adversely affect its internal growth. If the Company is not able to continue its historical levels of
growth, it may not be able to maintain its historical earnings trends.

If the Company is unable to manage its growth effectively, its operations
could be negatively affected.

Companies that experience rapid growth face various risks and difficulties, including:

In addition, in order to manage its growth and maintain adequate information and reporting systems within its organization, the Company must identify, hire and retain additional qualified employees, particularly in the accounting and
operational areas of its business.

If the Company does not manage its growth effectively, its business, financial condition, results of
operations and future prospects could be negatively affected, and the Company may not be able to continue to implement its business strategy and successfully conduct its operations.

Difficult market conditions and economic trends have adversely affected the banking industry and could adversely affect the Companys business, financial condition, results of operations and
cash flows.

The Company is operating in a challenging and uncertain economic environment, including generally uncertain conditions
nationally and locally in its markets. Financial institutions continue to be affected by declines in the real estate market that have negatively impacted the credit performance of mortgage, construction and commercial real estate loans and resulted
in significant write-downs of assets by many financial institutions. Concerns over the stability of the financial markets and the economy have resulted in decreased lending by financial institutions to their customers and to each other. The Company
retains direct exposure to the residential and commercial real estate markets, and it is affected by these events. Continued declines in real estate values, home sales volumes and financial stress on borrowers as a result of the uncertain economic
environment, including job losses, could have an adverse affect on the Companys borrowers or their customers, which could adversely affect the Companys business, financial condition, results of operations and cash flows.

The Companys ability to assess the creditworthiness of customers and to estimate the losses
inherent in its credit portfolio is made more complex by these difficult market and economic conditions. The Company also expects to face increased regulation and government oversight as a result of these downward trends. This increased government
action may increase the Companys costs and limit its ability to pursue certain business opportunities. In addition, the Company may be required to pay even higher FDIC deposit insurance premiums than the recently increased level, because
financial institution failures resulting from the depressed market conditions and other factors have depleted and may continue to deplete the deposit insurance fund and reduce its ratio of reserves to insured deposits.

A prolonged national economic recession or further deterioration of these conditions in the Companys markets could drive losses beyond that which
is provided for in its allowance for credit losses and result in the following consequences:



| |  |  | increases in loan delinquencies;
| | - |  | --------------------------------



| |  |  | increases in nonperforming assets and foreclosures;
| | - |  | ---------------------------------------------------



| |  |  | decreases in demand for the Companys products and services, which could adversely affect its liquidity position; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | decreases in the value of the collateral securing the Companys loans, especially real estate, which could reduce customers borrowing power.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------

The Company does not believe these difficult conditions are likely to improve in the near future. A worsening of these
conditions would likely exacerbate the adverse effects of these difficult economic conditions on the Company, its customers and the other financial institutions in its market. As a result, the Company may experience increases in foreclosures,
delinquencies and customer bankruptcies, as well as more restricted access to funds.

The U.S. Treasury and the FDIC have initiated
programs to address economic stabilization, yet the efficacy of these programs in stabilizing the economy and the banking system at large are uncertain.

Current levels of market volatility are unprecedented and could adversely impact the Companys results of operations and access to capital.

The capital and credit markets have been experiencing volatility and disruption for more than a year. In recent months, the volatility and disruption has reached unprecedented levels. In some cases, the markets have
produced downward pressure on stock prices and credit capacity for certain issuers without regard to those issuers underlying financial strength. If the current levels of market disruption and volatility continue or worsen, there can be no
assurance that the Company will not experience further adverse effects, which may be material, on its ability to access capital and on its business, financial condition and results of operations.

Liquidity risk could impair the Companys ability to fund operations and jeopardize its financial condition.

Liquidity is essential to the Companys business. An inability to raise funds through deposits, borrowings, the sale of loans and other sources
could have a substantial negative effect on its liquidity. The Companys access to funding sources in amounts adequate to finance its activities or on terms which are acceptable to it could be impaired by factors that affect the Company
specifically or the financial services industry or economy in general. Factors that could detrimentally impact the Companys access to liquidity sources include a decrease in the level of its business activity as a result of a downturn in the
markets in which its loans are concentrated or adverse regulatory action against it. The Companys ability to borrow could also be impaired by factors that are not specific to it, such as a disruption in the financial markets or negative views
and expectations about the prospects for the financial services industry in light of the recent turmoil faced by banking organizations and the continued deterioration in credit markets.

If the Company is unable to identify and acquire other financial institutions and successfully integrate its
acquired businesses, its business and earnings may be negatively affected.

The market for acquisitions remains highly competitive,
and the Company may be unable to find acquisition candidates in the future that fit its acquisition and growth strategy. To the extent that the Company is unable to find suitable acquisition candidates, an important component of its growth strategy
may be lost.

Acquisitions of financial institutions involve operational risks and uncertainties and acquired companies may have unforeseen
liabilities, exposure to asset quality problems, key employee and customer retention problems and other problems that could negatively affect the Companys organization. The Company may not be able to complete future acquisitions and, if
completed, the Company may not be able to successfully integrate the operations, management, products and services of the entities that it acquires and eliminate redundancies. The integration process could result in the loss of key employees or
disruption of the combined entitys ongoing business or inconsistencies in standards, controls, procedures and policies that adversely affect the Companys ability to maintain relationships with customers and employees or achieve the
anticipated benefits of the transaction. The integration process may also require significant time and attention from the Companys management that they would otherwise direct at servicing existing business and developing new business. The
Companys failure to successfully integrate the entities it acquires into its existing operations may increase its operating costs significantly and adversely affect its business and earnings.

The Companys dependence on loans secured by real estate subjects it to risks relating to fluctuations in the real estate market and related interest rates
and legislation that could require additional capital and could adversely affect its financial condition, results of operations and cash flows.

Approximately 81% of the Companys total loans as of December 31, 2008 consisted of loans included in the real estate loan portfolio with 18.7% in construction, 21.7% in residential real estate and 40.4% in
commercial real estate. The real estate collateral in each case provides an alternate source of repayment in the event of default by the borrower and may deteriorate in value during the time the credit is extended. A weakening of the real estate
market in the Companys primary market areas could have an adverse effect on the demand for new loans, the ability of borrowers to repay outstanding loans, the value of real estate and other collateral securing the loans and the value of real
estate owned by the Company. If real estate values decline, it is also more likely that the Company would be required to increase its allowance for credit losses, which could adversely affect its financial condition, results of operations and cash
flows.

As of December 31, 2008, the Company had $666.1 million or 18.7% of total loans in construction and land development loans.
Construction loans are subject to risks during the construction phase that are not present in standard residential real estate and commercial real estate loans. These risks include:



| |  |  | the viability of the contractor;
| | - |  | --------------------------------



| |  |  | the contractors ability to complete the project, to meet deadlines and time schedules and to stay within cost estimates; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | concentrations of such loans with a single contractor and its affiliates.
| | - |  | -------------------------------------------------------------------------

Real estate construction loans also present risks of default in the event of declines in property values or volatility in the real estate market during
the construction phase. If the Company is forced to foreclose on a project prior to completion, it may not be able to recover the entire unpaid portion of the loan, may be required to fund additional amounts to complete a project and may have to
hold the property for an indeterminate amount of time. If any of these risks were to occur, it could adversely affect the Companys financial condition, results of operations and cash flows.

In December 2006, banking regulators issued guidance regarding high concentrations of commercial and real estate construction loans within bank loan
portfolios. The guidance requires institutions that exceed certain



18



---

##### Table of Contents

levels of real estate lending to maintain higher capital ratios than institutions with lower concentrations if they do not have appropriate risk management
policies and practices in place. If there is any deterioration in the Companys commercial mortgage or construction and land development portfolios or if its regulators conclude that the Company has not implemented appropriate risk management
policies and practices, it could adversely affect the Companys business and result in a requirement of increased capital levels, and such capital may not be available at that time.

The Companys business is subject to interest rate risk and fluctuations in interest rates may adversely affect its earnings and capital levels.

The majority of the Companys assets are monetary in nature and, as a result, the Company is subject to significant risk from changes in interest
rates. Changes in interest rates can impact the Companys net interest income as well as the valuation of its assets and liabilities. The Companys earnings and cash flows are significantly dependent on its net interest income. Net
interest income is the difference between the interest income earned on loans, investment securities and other interest-earning assets and the interest expense paid on deposits, borrowings and other interest-bearing liabilities. Therefore, any
change in general market interest rates, such as a change in the monetary policy of the Federal Reserve Board or otherwise, can have a significant effect on the Companys net interest income. The Companys assets and liabilities may react
differently to changes in overall market rates or conditions because there may be mismatches between the repricing or maturity characteristics of the assets and liabilities.

The Companys profitability depends significantly on local economic conditions.

The
Companys success depends primarily on the general economic conditions of the primary markets in Texas in which it operates and where its loans are concentrated. Unlike larger banks that are more geographically diversified, the Company provides
banking and financial services to customers primarily in the greater Houston and Dallas metropolitan areas and in the east, central, north central, south central and southeast areas of Texas. The local economic conditions in these areas have a
significant impact on the Companys commercial, real estate and construction and land development loans, the ability of its borrowers to repay their loans and the value of the collateral securing these loans. In addition, if the population or
income growth in the Companys market areas is slower than projected, income levels, deposits and housing starts could be adversely affected and could result in a reduction of the Companys expansion, growth and profitability. Although
economic conditions in Texas have not deteriorated to the same extent as in other areas, such conditions are declining and are expected to continue to decline. If the Companys market areas experience a downturn or a recession for a prolonged
period of time, the Company would likely experience significant increases in nonperforming loans, which could lead to operating losses, impaired liquidity and eroding capital. A significant decline in general economic conditions, caused by
inflation, recession, acts of terrorism, outbreak of hostilities or other international or domestic calamities, unemployment or other factors could impact these local economic conditions and could negatively affect the Companys financial
condition, results of operations and cash flows.

The Companys allowance for credit losses may not be sufficient to cover actual credit losses,
which could adversely affect its earnings.

As a lender, the Company is exposed to the risk that its loan customers may not repay
their loans according to the terms of these loans and the collateral securing the payment of these loans may be insufficient to fully compensate the Company for the outstanding balance of the loan plus the costs to dispose of the collateral.
Management makes various assumptions and judgments about the collectibility of the Companys loan portfolio, including the diversification by industry of its commercial loan portfolio, the amount of nonperforming assets and related collateral,
the volume, growth and composition of its loan portfolio, the effects on the loan portfolio of current economic indicators and their probable impact on borrowers and the evaluation of its loan portfolio through its internal loan review process and
other relevant factors.



19

##### Table of Contents

The Company maintains an allowance for credit losses in an attempt to cover estimated losses inherent in
its loan portfolio. Additional credit losses will likely occur in the future and may occur at a rate greater than the Company has experienced to date. In determining the size of the allowance, the Company relies on an analysis of its loan portfolio,
its historical loss experience and its evaluation of general economic conditions. Continuing deterioration in economic conditions affecting borrowers, new information regarding existing loans, identification of additional problem loans and other
factors, both within and outside of the Companys control, may require an increase in the allowance for loan losses. If the Companys assumptions prove to be incorrect or if it experiences significant loan losses in future periods, its
current allowance may not be sufficient to cover actual loan losses and adjustments may be necessary to allow for different economic conditions or adverse developments in its loan portfolio. A material addition to the allowance could cause net
income and possibly, capital, to decrease.

In addition, federal and state regulators periodically review the Companys allowance for
credit losses and may require the Company to increase its provision for credit losses or recognize further charge-offs, based on judgments different than those of the Companys management. Any increase in the Companys allowance for credit
losses or charge-offs as required by these regulatory agencies could have a material adverse effect on the Companys operating results, financial condition and cash flows.

The small to medium-sized businesses that the Company lends to may have fewer resources to weather a downturn in the economy, which may impair a borrowers ability to repay a loan to the Company that could
materially harm the Companys operating results.

The Company targets its business development and marketing strategy primarily
to serve the banking and financial services needs of small to medium-sized businesses. These small to medium-sized businesses frequently have smaller market share than their competition, may be more vulnerable to economic downturns, often need
substantial additional capital to expand or compete and may experience significant volatility in operating results. Any one or more of these factors may impair the borrowers ability to repay a loan. In addition, the success of a small to
medium-sized business often depends on the management talents and efforts of one or two persons or a small group of persons, and the death, disability or resignation of one or more of these persons could have a material adverse impact on the
business and its ability to repay a loan. Economic downturns and other events that negatively impact the Companys market areas could cause the Company to incur substantial credit losses that could negatively affect the Companys results
of operations, financial condition and cash flows.

If the goodwill that the Company recorded in connection with a business acquisition becomes
impaired, it could require charges to earnings, which would have a negative impact on the Companys financial condition, results of operations and cash flows.

Goodwill represents the amount of acquisition cost over the fair value of net assets the Company acquired in the purchase of another financial institution. The Company reviews goodwill for impairment at least
annually, or more frequently if events or changes in circumstances indicate the carrying value of the asset might be impaired.

The Company
determines impairment by comparing the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of the reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment
loss is recognized in an amount equal to that excess. Any such adjustments are reflected in the Companys results of operations in the periods in which they become known. At December 31, 2008, the Companys goodwill totaled $874.7 million.
While the Company has not recorded any such impairment charges since it initially recorded the goodwill, there can be no assurance that the Companys future evaluations of goodwill will not result in findings of impairment and related
write-downs, which may have a material adverse effect on its financial condition, results of operations and cash flows.

The Company may need to raise additional capital in the future and such capital may not be available when needed or
at all.

The Company may need to raise additional capital in the future to provide it with sufficient capital resources and
liquidity to meet its commitments and business needs. In addition, the Company may elect to raise additional capital to support its business or to finance acquisitions, if any. The Companys ability to raise additional capital, if needed, will
depend on, among other things, conditions in the capital markets at that time, which are outside of its control, and its financial performance. The ongoing liquidity crisis and the loss of confidence in financial institutions may increase the
Companys cost of funding and limit its access to some of its customary sources of capital, including, but not limited to, inter-bank borrowings, repurchase agreements and borrowings from the discount window of the Federal Reserve.

The Company cannot assure you that such capital will be available to it on acceptable terms or at all. Any occurrence that may limit its access to the
capital markets, such as a decline in the confidence of investors, depositors of the Banks or counterparties participating in the capital markets, may adversely affect the Companys capital costs and its ability to raise capital and, in turn,
its liquidity. An inability to raise additional capital on acceptable terms when needed could have a material adverse effect on the Companys business, financial condition and results of operations.

An interruption in or breach in security of the Companys information systems may result in a loss of customer business and have an adverse affect on the
Companys results of operations, financial condition and cash flows.

The Company relies heavily on communications and
information systems to conduct its business. Any failure, interruption or breach in security of these systems could result in failures or disruptions in the Companys customer relationship management, general ledger, deposits, servicing or loan
origination systems. Although the Company has policies and procedures designed to prevent or minimize the effect of a failure, interruption or breach in security of its communications or information systems, there can be no assurance that any such
failures, interruptions or security breaches will not occur, or if they do occur, that they will be adequately addressed by the Company. The occurrence of any such failures, interruptions or security breaches could result in a loss of customer
business and have a negative effect on the Companys results of operations, financial condition and cash flows.

The business of the Company is
dependent on technology and the Companys inability to invest in technological improvements may adversely affect its results of operations, financial condition and cash flows.

The financial services industry is undergoing rapid technological changes with frequent introductions of new technology-driven products and services. In
addition to better serving customers, the effective use of technology increases efficiency and enables financial institutions to reduce costs. The Companys future success depends in part upon its ability to address the needs of its customers
by using technology to provide products and services that will satisfy customer demands for convenience as well as create additional efficiencies in its operations. Many of the Companys competitors have substantially greater resources to
invest in technological improvements. The Company may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to its customers, which may negatively affect the
Companys results of operations, financial condition and cash flows.

The Company operates in a highly regulated environment and, as a result,
is subject to extensive regulation and supervision; and changes in federal, state and local laws and regulations could adversely affect its financial performance.

The Company and the Bank are subject to extensive regulation, supervision and examination by federal and state banking authorities. Any change in applicable regulations or federal or state legislation could have a
substantial impact on the Company, its subsidiary bank, and their respective operations. Additional legislation



21

##### Table of Contents

and regulations may be enacted or adopted in the future that could significantly affect the Companys powers, authority and operations, or the powers,
authority and operations of the Bank, which could have a material adverse effect on the Companys financial condition and results of operations. Further, regulators have significant discretion and power to prevent or remedy unsafe or unsound
practices or violations of laws by banks and bank holding companies in the performance of their supervisory and enforcement duties. The exercise of this regulatory discretion and power may have a negative impact on the Company.

Risks Associated with the Companys Common Stock

The
Companys corporate organizational documents and the provisions of Texas law to which it is subject may delay or prevent a change in control of the Company that you may favor.

The Companys amended and restated articles of incorporation and amended and restated bylaws contain various provisions which may delay, discourage
or prevent an attempted acquisition or change of control of the Company. These provisions include:



| |  |  | a board of directors classified into three classes of directors with the directors of each class having staggered three-year terms;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------



| |  |  | a provision that any special meeting of the Companys shareholders may be called only by the chairman of the board and chief executive officer, the president,
a majority of the board of directors or the holders of at least 50% of the Companys shares entitled to vote at the meeting;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a provision establishing certain advance notice procedures for nomination of candidates for election as directors and for shareholder proposals to be considered at
an annual or special meeting of shareholders; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a provision that denies shareholders the right to amend the Companys bylaws.
| | - |  | -----------------------------------------------------------------------------

The Companys articles of incorporation provide for noncumulative voting for directors and authorize the board of directors to issue shares of its
preferred stock without shareholder approval and upon such terms as the board of directors may determine. The issuance of the Companys preferred stock could have the effect of making it more difficult for a third party to acquire, or of
discouraging a third party from acquiring, a controlling interest in the Company. In addition, certain provisions of Texas law, including a provision which restricts certain business combinations between a Texas corporation and certain affiliated
shareholders, may delay, discourage or prevent an attempted acquisition or change in control of the Company.

The holders of the Companys
junior subordinated debentures have rights that are senior to those of the Companys shareholders.

As of December 31,
2008, the Company had $92.3 million in junior subordinated debentures outstanding that were issued to the Companys unconsolidated subsidiary trusts. The subsidiary trusts purchased the junior subordinated debentures from the Company using the
proceeds from the sale of trust preferred securities to third party investors. Payments of the principal and interest on the trust preferred securities are conditionally guaranteed by the Company to the extent not paid or made by each trust,
provided the trust has funds available for such obligations.

The junior subordinated debentures are senior to the Companys shares of
Common Stock. As a result, the Company must make interest payments on the junior subordinated debentures (and the related trust preferred securities) before any dividends can be paid on its Common Stock; and, in the event of the Companys
bankruptcy, dissolution or liquidation, the holders of the debentures must be satisfied before any distributions can be made to the holders of the Common Stock. Additionally, the Company has the right to defer periodic distributions on the junior
subordinated debentures (and the related trust preferred securities) for up to five years, during which time the Company would be prohibited from paying dividends on its Common Stock. The Companys ability to pay the future distributions
depends upon the earnings of the Bank and dividends from the Bank to the Company, which may be inadequate to service the obligations.

Dividends

Holders of Common Stock are entitled to receive dividends when, as and if declared by the Companys Board of Directors out of funds legally available therefor. While the Company has declared dividends on its
Common Stock since 1994, and paid quarterly dividends aggregating $0.5125 per share in 2008 and $0.4625 share in 2007, there is no assurance that the Company will continue to pay dividends in the future. Future dividends on the Common Stock will
depend upon the Companys earnings and financial condition, liquidity and capital requirements, the general economic and regulatory climate, the Companys ability to service any equity or debt obligations senior to the Common Stock and
other factors deemed relevant by the board of directors of the Company.

As a holding company, the Company is ultimately dependent upon its
subsidiaries to provide funding for its operating expenses, debt service and dividends. Various banking laws applicable to the Bank limit the payment of dividends and other distributions by the Bank to the Company, and may therefore limit the
Companys ability to pay dividends on its Common Stock. If required payments on the Companys outstanding junior subordinated debentures held by its unconsolidated subsidiary trusts are not made or suspended, the Company will be prohibited
from paying dividends on its Common Stock. Regulatory authorities could impose administratively stricter limitations on the ability of the Bank to pay dividends to the Company if such limits were deemed appropriate to preserve certain capital
adequacy requirements.

The cash dividends declared per share by quarter (and paid on the first business day of the subsequent quarter) for
the Companys last two fiscal years were as follows:



|               |  |      |        |      |   |

Managements Discussion and Analysis of Financial Condition and Results of Operations analyzes the major elements of the Companys balance
sheets and statements of income. This section should be read in conjunction with the Companys consolidated financial statements and accompanying notes and other detailed information appearing elsewhere in this Annual Report on Form 10-K.

For the Years Ended December 31, 2008, 2007 and 2006

Overview

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. Net interest income is
the Companys largest source of revenue. The level of interest rates and the volume and mix of earning assets and interest-bearing liabilities impact net interest income and margin. The Company has recognized increased net interest income due
primarily to an increase in the volume of interest-earning assets.

Three principal
components of the Companys growth strategy are internal growth, stringent cost control practices and strategic merger transactions. The Company focuses on continual internal growth. Each banking center is operated as a separate profit center,
maintaining separate data with respect to its net interest income, efficiency ratio, deposit growth, loan growth and overall profitability. Banking center presidents and managers are accountable for performance in these areas and compensated
accordingly. The Company also focuses on maintaining stringent cost control practices and policies. The Company has invested significantly in the infrastructure required to centralize many of its critical operations, such as data processing and loan
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 April 1, 2006, the Company acquired SNB Bancshares, Inc. (the SNB acquisition) which added five (5) banking centers. At the time of acquisition, SNB had an additional banking office under
construction in Katy, Texas, which became a full-service banking center of the Company upon completion in July 2006. During 2007, forty-one (41) banking centers were acquired in the acquisition of Texas United Bancshares, Inc. (the TXUI
acquisition). The acquisition of The Bank of Navasota, N.A. (the Navasota acquisition) was completed on September 1, 2007 and added one (1) banking center. During 2008, the Company acquired six (6) branches of Banco
Popular North America in January, completed the acquisition of 1stChoice Bancorp, Inc on June 1 which added one (1) banking center and
assumed $3.6 billion in deposits and acquired certain assets from the FDIC acting in its capacity as receiver for Franklin Bank in November which initially added forty-five (45) banking centers, ten (10) of which will be closed and consolidated
with nearby banking centers in the first quarter of 2009.

Net income was $84.5
million, $84.2 million and $61.7 million for the years ended December 31, 2008, 2007 and 2006, respectively, and diluted earnings per share were $1.86, $1.94 and $1.94, respectively, for these same periods. The change in net income during both
2008 and 2007 resulted principally from an increase in net interest income and acquisitions, including the Banco Popular and 1stChoice acquisitions
and the Franklin Bank

acquisition, offset by an increase in write-down on perpetual preferred securities issued by Federal Home Loan Mortgage Corporation (FHLMC or
Freddie Mac) and Federal National Mortgage Association (FNMA or Fannie Mae). Net income growth during 2006 resulted principally from an increase in loan volume and acquisitions, including the SNB acquisition. The Company posted returns
on average assets of 1.20%, 1.38% and 1.44% and returns on average equity of 7.09%, 8.09% and 10.24% for the years ended December 31, 2008, 2007 and 2006, respectively. The Companys efficiency ratio was 46.51% in 2008, 46.19% in 2007 and
45.27% in 2006. 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.

The Company recognized an other-than-temporary
impairment charge of $14.0 million pre-tax ($9.1 million after-tax) for the year ended December 31, 2008 on Freddie Mac and on Fannie Mae government sponsored, investment grade perpetual callable preferred securities. The
other-than-temporary-impairment charge was recorded on six perpetual preferred stock issues classified as available for sale investment securities with a total book value (prior to recognition of the impairment charge) of $14.0 million. The Company
reclassified the unrealized mark-to-market loss on these investment grade securities to an other-than-temporary impairment charge because of the significant decline in the market value of these securities and because management believes it is
unlikely that these securities will recover their original book value within a reasonable amount of time. Both FHLMC and FNMA securities were investment grade at the time of purchase. The Company also recognized an impairment charge of $10.0 million
pre-tax ($6.5 million after tax) on the same securities for the year ended December 31, 2007. Market value decreases on available for sale securities which are not other-than-temporary are recorded as an unrealized mark-to-market loss and
reflected as a reduction to shareholders equity through other comprehensive income. Accordingly, the reclassification of the unrealized after tax loss to an other-than-temporary impairment non-cash charge did not affect shareholders
equity or tangible shareholders equity.

Total assets at December 31, 2008 and 2007 were $9.072 billion and $6.372 billion,
respectively. Total deposits at December 31, 2008 and 2007 were $7.303 billion and $4.966 billion, respectively. Total loans were $3.567 billion at December 31, 2008, an increase of $424.1 million or 13.5% compared with $3.143 billion at
December 31, 2007. At December 31, 2008, the Company had $9.7 million in nonperforming loans and its allowance for credit losses was $37.0 million compared with $5.1 million in nonperforming loans and an allowance for credit losses of
$32.5 million at December 31, 2007. Shareholders equity was $1.255 billion and $1.127 billion at December 31, 2008 and 2007, respectively.

In response to global credit and liquidity issues involving a number of financial institutions, the United States government, particularly the U.S. Treasury and the FDIC, have taken a variety of extraordinary measures
designed to restore confidence in the financial markets and to strengthen financial institutions, including capital injections, guarantees of bank liabilities and the acquisition of illiquid assets from banks.

On October 3, 2008, the Emergency Economic Stabilization Act of 2008 was signed into law, which granted the U.S. Treasury the authority to take a range
of actions for the purpose of stabilizing and providing liquidity to the U.S. financial markets and has proposed several programs, including the direct purchase by the U.S. Treasury of equity of healthy financial institutions under the Capital
Purchase Program. The Company elected not to participate in the Capital Purchase Program. The EESA also temporarily raised the limit on federal deposit insurance coverage provided by the FDIC from $100,000 to $250,000 per depositor. Among other
programs and actions taken by the U.S. regulatory agencies, the FDIC implemented the Temporary Liquidity Guarantee Program to strengthen confidence and encourage liquidity in the banking system. The Company cannot predict at this time the effect
that the recent legislative initiatives may have on its business, financial condition or results of operations. For additional details about the recent legislative initiatives, please refer to the section captioned Supervision and
RegulationLegislative Initiatives in Part I, Item I of this Annual Report on Form 10-K.

2008 Acquisitions

On November 7, 2008, the Bank assumed approximately $3.6 billion of deposits and acquired certain assets from the FDIC, acting in its capacity as
receiver for Franklin Bank. The FDIC entered into a purchase and assumption agreement with the Bank, which paid a premium of $60.9 million to ensure that all deposits of Franklin Bank, both insured and uninsured, were transferred to it. Under terms
of the purchase and assumption agreement, the Bank acquired certain assets from the FDIC, including approximately $350 million in U.S. Treasury and Agency Securities and approximately $360 million in performing loans. The remaining net proceeds were
predominately invested in mortgage backed securities primarily issued by federal government agencies such as Ginnie Mae, Freddie Mac and Fannie Mae. The purchase and assumption transaction was accounted for as a business acquisition in accordance
with SFAS 141.

The purchase and assumption agreement also provided the Bank with an option to purchase at fair value any or all of
the owned premises of the banking offices of Franklin Bank and to assume the leases of the leased banking offices by providing written notice to the FDIC within 120 days after November 7, 2008. The Bank intends to purchase
twenty-nine (29) of the owned banking offices for an aggregate of approximately $27.0 million and to assume the leases for six (6) banking offices. In addition, under the terms of the purchase and assumption agreement the Bank is
required to purchase the furniture, fixtures and equipment at any banking office it purchases or leases. Accordingly, the Bank intends to purchase approximately $2.0 million in furniture, fixtures and equipment from the
FDIC. The Bank expects to complete these purchases in the second quarter of 2009.

While Franklin Bank operated forty-five
(45) full service banking offices, the Company expects to continue to operate no more than thirty-five (35) of these locations upon the completion of the operational integration expected to occur during the first quarter of 2009. The
former Franklin Bank locations planned to be closed will be consolidated into nearby existing banking centers.

On June 1, 2008, the
Company completed its acquisition of 1st Choice Bancorp, Inc and its wholly-owned subsidiary, 1st Choice Bank. 1st Choice operated two (2) banking offices in Houston, Texas, with one location in South Houston and another in the Heights area.
Prosperitys Heights banking center was consolidated with the 1st Choice Heights location, with the resulting banking center being located in 1st Choices Heights banking office. As of March 31, 2008, 1st Choice had, on a consolidated
basis, total assets of $313.9 million, loans of $198.9 million, deposits of $285.1 million and stockholders equity of $27.5 million. Under the terms of the definitive agreement, the Company issued 1,757,752 shares of its Common Stock plus
approximately $18,758,000 in cash for all outstanding shares of 1st Choice.

On January 10, 2008, the Company completed its
acquisition of six (6) Houston retail branches from Banco Popular North America. In connection with the acquisition, the Company assumed approximately $125.0 million in deposits and six (6) banking centers. In the second quarter of 2008,
one banking center was closed and consolidated with a nearby existing banking center.

Critical Accounting Policies

The Companys significant accounting policies are integral to understanding the results reported. The Companys accounting
policies are described in detail in Note 1 to the consolidated financial statements. 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 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 and Intangible AssetsGoodwill and intangible assets that have indefinite useful lives are subject to an impairment test at least annually and more frequently if circumstances indicate their value
may not be recoverable. Goodwill is tested for impairment using a two-step process that begins with an estimation of the fair value of each of the Companys reporting units compared with its carrying value. If the carrying amount exceeds the
fair value of a reporting unit, a second 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 December 31, 2008. While the Company believes no impairment existed at December 31, 2008
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 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. 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 financial condition and near-term prospects of the issuer, as well as the value of any security we may have in the
investment. Often, the information available to conduct these assessments is limited and rapidly changing, making estimates of fair value subject to judgment. If actual information or conditions are different than estimated, the extent of the
impairment of the security may be different than previously estimated, which could have a material effect on the Companys results of operations and financial condition.

Results of Operations

Net Interest Income

The Companys operating results depend primarily on its net interest
income, which is the difference between interest income on interest-earning assets, including securities and loans, and interest expense incurred on interest-bearing liabilities, including deposits and other borrowed funds. Interest rate
fluctuations, as well as changes in the amount and type of earning assets and liabilities, combine to affect 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.

2008 versus 2007. Net interest income before the provision for credit losses for the year ended December 31,
2008 was $227.7 million compared with $200.4 million for the year ended December 31, 2007, an increase of $27.3 million or 13.6%. The improvement in net interest income for 2008 was principally due to a $810.1 million or 16.2% increase in
average interest-earning assets to $5.824 billion at December 31, 2008 compared with $5.014 billion at December 31, 2007. The increase in average interest-earning assets was primarily due to the Franklin Bank transaction. The improvement
in net interest income for 2008 was also partially due to a decrease in the yield on interest-earning assets that was less than the decrease in rates paid on interest-bearing liabilities. The average rate paid on interest-bearing liabilities
decreased 97 basis points from 3.63% for the year ended December 31, 2007 to 2.66% for the year ended December 31, 2008 and the average yield on interest-earning assets decreased 82 basis points from 6.79% at December 31, 2007 to
5.97% at December 31, 2008. At December 31, 2008, period end demand deposits represented an important component of funding and were 20.9% of total period end deposits compared with 23.5% at December 31, 2007.

Net interest margin on a tax equivalent basis, defined as net interest income divided by average interest-earning assets, for 2008 was 3.96%, down 10
basis points from 4.06% for 2007.

2007 versus 2006. Net interest income before the provision for credit losses for the year ended
December 31, 2007 was $200.4 million compared with $138.1 million for the year ended December 31, 2006, an increase of $62.3 million or 45.1%. The improvement in net interest income for 2007 was principally due to a $1.332 billion or 36.2%
increase in average interest-earning assets to $5.014 billion at December 31, 2007 compared with $3.682 billion at December 31 2006. The increase in average interest-earning assets was primarily due to the TXUI acquisition. The improvement
in net interest income for 2007 was also partially due to an increase in the yield on interest-earning assets. The average rate paid on interest-bearing liabilities increased 37 basis points from 3.26% for the year ended December 31, 2006 to
3.63% for the year ended December 31, 2007 and average yield on interest-earning assets increased 50 basis points from 6.29% at December 31, 2006 to 6.79% at December 31, 2007. At December 31, 2007, period end demand deposits
represented an important component of funding and were 23.5% of total period end deposits compared with 22.4% at December 31, 2006.

Net interest margin on a tax equivalent basis for 2007 was 4.06%, up 26 basis points from 3.80% for 2006.

##### Table of Contents

The following table presents information regarding the dollar amount of changes in interest income and
interest expense for the periods indicated for each major component of interest-earning assets and interest-bearing liabilities and distinguishes between the changes attributable to changes in volume and changes in interest rates. For purposes of
this table, changes attributable to both rate and volume which cannot be segregated have been allocated to rate.

Provision for Credit Losses

The Companys provision for credit losses is established through charges to income in the form of the provision in order to bring the Companys allowance for credit losses to a level deemed appropriate by
management based on the factors discussed under Financial ConditionAllowance for Credit Losses. The allowance for credit losses at December 31, 2008 was $37.0 million, representing 1.04% of outstanding loans as of such date.
The provision for credit losses for the year ended December 31, 2008 was $9.9 million compared with $760,000 for the year ended December 31, 2007. Net charge-offs for the year ended December 31, 2008 were $7.6 million compared with
$5.6 million in net charge-offs for the year ended December 31, 2007. The increased charge-offs were mainly due to the loans acquired in the TXUI acquisition. The provision for credit losses for the year ended December 31, 2007 was
$760,000 compared with $504,000 for the year ended December 31, 2006. Net charge-offs for the year ended December 31, 2006 were $771,000.

Noninterest Income

The Companys primary sources of recurring 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. For the year ended December 31, 2008, noninterest income totaled $52.4 million, a decrease of $553,000 or 1.0%

compared with $52.9 million in 2007. The decrease was primarily due to a decrease in gains on held for sale loans and an increase in loss on sale of other
real estate, offset by an increase in insufficient funds charges and customer service charges which resulted from an increase in the number of accounts due to the acquisition of six (6) branches of Banco Popular and the 1stChoice and Franklin Bank acquisitions in 2008. As of December 31, 2008, the three transactions added approximately 129,000 deposit accounts including
certificates of deposits and over 45,000 debit cards. Noninterest income for 2007 was $52.9 million, an increase of $18.9 million or 55.7% compared with $34.0 million in 2006, resulting largely from an increase in service charges due to the
additional deposit accounts from the TXUI acquisition completed in January 2007 and the Bank of Navasota acquisition in September 2007.

Trust and investment income decreased $809,000 to $393,000 for the year ended December 31, 2008 compared with $1.2 million for the year ended December 31, 2007. The decrease was primarily due to the dissolution of the trust and
investment department acquired in February 2007 in conjunction with the TXUI acquisition.

Gain on sale of held for sale loans decreased
$1.1 million from $1.3 million for the year ended December 31, 2007 to $229,000 for the year ended December 31, 2008. During 2007, loans were originated for the purpose of sale into the secondary market in connection with mortgage banking
activities acquired in the TXUI acquisition. The Company ceased to originate any new loans for sale into the secondary market in 2008 and does not intend to continue to originate loans for sale in the future.

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

Noninterest Expense

For the year ended December 31, 2008, noninterest expense totaled $143.8 million, an increase of $17.0 million or 13.4% compared
with $126.8 million for the same period in 2007. This increase was principally due to increases in salaries and employee benefits, net occupancy and the increase in impairment write-down on Fannie Mae and Freddie Mac preferred stock discussed
further under Securities. For the year ended December 31, 2007, noninterest expense totaled $126.8 million, an increase of $49.2 million or 63.3% compared with $77.7 million for the same period in 2006. The increase was
primarily attributable to increases in salaries

Salaries and Employee Benefits. Salaries and employee benefits increased $6.9 million to $70.8 million at December 31, 2008 compared with
$63.9 million at December 31, 2007 primarily due to staff added with the Franklin Bank acquisition in November 2008. The number of associates employed by the Company increased from 1,359 at December 31, 2007 to 1,734 at December 31,
2008. Salaries and employee benefits increased $22.6 million from $41.3 million at December 31, 2006 to $63.9 million at December 31, 2007 primarily due to staff added with the TXUI acquisition. The number of associates employed by the
Company increased from 908 at December 31, 2006 to 1,359 at December 31, 2007. Total noninterest expense for the year ended December 31, 2008 includes $1.5 million in stock-based compensation expense compared with $2.0 million and
$850,000 recorded for the years ended December 31, 2007 and 2006, respectively.

Net Occupancy and Depreciation Expenses. Net
occupancy expense increased $1.9 million or 18.4% to $12.5 million for the year ended December 31, 2008 compared with $10.5 million for the year ended December 31, 2007. The increase was primarily attributable to the additional
banking centers acquired in 2008. Depreciation expense increased $55,000 to $7.7 million for the year ended December 31, 2008 compared with $7.6 million for the same period in 2007. Net occupancy expense increased $2.7 million or 33.6% to $10.5
million for the year ended December 31, 2007 compared with $7.9 million for the year ended December 31, 2006. Depreciation expense increased $2.6 million to $7.6 million compared with $5.0 million for the same periods. These increases
were primarily attributable to the additional acquisitions in 2006 and 2007 which added forty-two (42) banking centers.

Communications Expense. Communications expense includes telephone, data circuits, postage and courier expenses. Communications expense increased $231,000 or 3.6% from $6.4 million for the year ended December 31, 2007 to $6.6
million for the year ended December 31, 2008. The increase was primarily associated with the 2008 acquisitions including the Franklin Bank acquisition. Communications expense increased $2.0 million or 46.4% from $4.3 million for the year ended
December 31, 2006 to $6.4 million for the year ended December 31, 2007. The increase was primarily associated with the TXUI acquisition.

Core Deposit Intangibles Amortization. Core deposit intangibles (CDI) amortization
decreased $120,000 or 1.2% from $9.9 million for the year December 31, 2007 to $9.8 million for the year ended December 31, 2008. Although the Bank completed the Franklin acquisition in November 2008, the Company has not yet determined the
allocation of the purchase price to CDI with respect to the Franklin Bank deposits assumed and accordingly no amortization expense was recorded in 2008. The Company expects the completion of the allocation to result in an increase in CDI and a
corresponding increase in amortization expense in future periods. Core deposit intangibles amortization increased $5.0 million or 103.7% from $4.9 million for the year ended December 31, 2006 to $9.9 million for the year ended December 31,
2007. The increase was associated with the addition of $31.0 million in core deposit intangible assets related to the TXUI acquisition and $2.0 million in core deposit intangibles related to the Navasota acquisition. Core deposit intangibles are
being amortized on an accelerated basis over an estimated life of eight to ten years.

Other Noninterest Expense.Other operating
expenses increased $1.7 million or 15.8% from $10.5 million at December 31, 2007 to $12.1 million for the year ended December 31, 2008. The increase was primarily attributable to the additional general expenses incurred due to the Franklin
Bank acquisition. Other operating expenses increased $2.8 million or 36.8% from $7.7 million at December 31, 2006 to $10.5 million for the year ended December 31, 2007. The increase was primarily attributable to the additional general
expenses incurred due to the TXUI acquisition.

Efficiency Ratio. The efficiency ratio is a supplemental financial measure utilized
in managements internal evaluation of the Company and is not defined under generally accepted accounting principles. The efficiency ratio is calculated by dividing total noninterest expense, excluding credit loss provisions and impairment
write-down on available for sale securities, by net interest income plus noninterest income, excluding net gains and losses on the sale of securities and on the sale of assets. Taxes are not part of this calculation. An increase in the efficiency
ratio indicates that more resources are being utilized to generate the same volume of income, while a decrease would indicate a more efficient allocation of resources. The Companys efficiency ratio was 46.51% at December 31, 2008, an
increase from 46.19% at December 31, 2007. The Companys efficiency ratio was 45.27% at December 31, 2006.

Income Taxes

The amount of federal income tax expense is influenced by the amount of taxable income, the amount of tax-exempt income, the amount of nondeductible
interest expense and the amount of other nondeductible expenses. For the year ended December 31, 2008, income tax expense was $41.9 million compared with $41.6 million for the year ended December 31, 2007 and $32.2 million for the
year ended December 31, 2006. The increases were primarily attributable to higher pretax net earnings which resulted from an increase in net interest income for the year ended December 31, 2008 compared with the same period in 2007 and
2006. The effective tax rate for the years ended December 31, 2008, 2007 and 2006 was 33.2%, 33.1% and 34.3%, respectively. The effective income tax rates differed from the U.S. statutory rate of 35% during the comparable periods primarily due
to the effect of tax-exempt income from loans and securities.

Impact of Inflation

The Companys consolidated financial statements and related notes included in this annual report on Form 10-K have been prepared in accordance
with generally accepted accounting principles. These require the measurement of financial position and operating results in terms of historical dollars, without considering changes in the relative purchasing power of money over time due to
inflation.

Unlike many industrial companies, substantially all of the Companys assets and liabilities are monetary in nature. As a
result, interest rates have a more significant impact on the Companys performance than the effects of general levels of inflation. Interest rates may not necessarily move in the same direction or in the same magnitude as the prices of goods
and services. However, other expenses do reflect general levels of inflation.

Loan Portfolio

At December 31, 2008,
total loans were $3.567 billion, an increase of $424.1 million or 13.5% compared with $3.143 billion at December 31, 2007. The growth in loans was primarily attributable to the Franklin Bank acquisition, 1stChoice acquisition and the acquisition of six (6) branches of Banco Popular. At December 31, 2008, total loans at the banking centers acquired in 2008, including the
former Franklin Bank banking centers, totaled $528.2 million. At December 31, 2008, total loans were 48.8% of deposits and 39.3% of total assets. At December 31, 2007, total loans were 63.3% of deposits and 49.3% of total assets. Loans
increased 44.4% during 2007 from $2.177 billion at December 31, 2006 to $3.143 billion at December 31, 2007. The growth in loans was primarily attributable to internal growth and the TXUI acquisition.

The Company is focused on
growing its commercial and industrial and commercial mortgage loan portfolios. The Companys commercial and industrial loans grew from $436.3 million at December 31, 2007 to $482.5 million at December 31, 2008, an increase of $46.1
million or 10.6%. The Companys commercial mortgages grew from $1.075 billion at December 31, 2007 to $1.268 billion at December 31, 2008, an increase of $193.1 million or 18.0%. The Company offers a variety of commercial lending
products including term loans and lines of credit. The Company offers a broad range of short to medium-term commercial loans, primarily collateralized, to businesses for working capital (including inventory and receivables), business expansion
(including acquisitions of real estate and improvements) and the purchase of equipment and machinery. Historically, the Company has originated loans for its own account and has not securitized its loans. The purpose of a particular loan generally
determines its structure. All loans in the 1-4 family residential category were originated by the Company.

All loans over $500,000 and
below $2.5 million are evaluated and acted upon on a daily basis by two of the six company-wide loan concurrence officers. All loans above $2.5 million are evaluated and acted upon by an officers loan committee which meets weekly. In addition
to the officers loan committee evaluation, loans from $15.0 million to $25.0 million are evaluated and acted upon by the directors loan committee which consists of three directors of the Bank and meets as necessary. Loans over $25.0
million are evaluated and acted upon by the Banks board of directors either at a regularly scheduled monthly board meeting or by teleconference or written consent.

Commercial and Industrial Loans. In nearly all cases, the Companys commercial loans are made
in the Companys market areas and are underwritten on the basis of the borrowers ability to service the debt from income. As a general practice, the Company takes as collateral a lien on any available real estate, equipment or other
assets owned by the borrower and obtains a personal guaranty of the borrower or principal. Working capital loans are primarily collateralized by short-term assets whereas term loans are primarily collateralized by long-term assets. In general,
commercial loans involve more credit risk than residential mortgage loans and commercial mortgage loans and, therefore, usually yield a higher return. The increased risk in commercial loans is due to the type of collateral securing these loans. The
increased risk also derives from the expectation that commercial loans generally will be serviced principally from the operations of the business, and those operations may not be successful. Historical trends have shown these types of loans to have
higher delinquencies than mortgage loans. As a result of these additional complexities, variables and risks, commercial loans require more thorough underwriting and servicing than other types of loans.

Commercial Mortgages. The Company makes commercial mortgage loans collateralized by real estate to finance the purchase of real estate. The
Companys commercial mortgage loans are collateralized by first liens on real estate, typically have variable interest rates and amortize over a ten to 15 year period. Payments on loans secured by such properties are often dependent on the
successful operation or management of the properties. Accordingly, repayment of these loans may be subject to adverse conditions in the real estate market or the economy to a greater extent than other types of loans. The Company seeks to minimize
these risks in a variety of ways, including giving careful consideration to the propertys operating history, future operating projections, current and projected occupancy, location and physical condition in connection with underwriting these
loans. The underwriting analysis also includes credit verification, appraisals and a review of the financial condition of the borrower.

1-4 Family Residential Loans. The Companys lending activities also includes the origination of 1-4 family residential mortgage loans collateralized by owner-occupied residential properties located in the Companys market
areas. The Company offers a variety of mortgage loan products which generally are amortized over five to 25 years. Loans collateralized by 1-4 family residential real estate generally have been originated in amounts of no more than 90% of appraised
value or have mortgage insurance. The Company requires mortgage title insurance and hazard insurance. Other than with respect to mortgage banking activities acquired in the TXUI acquisition, the Company has elected to keep all 1-4 family residential
loans for its own account rather than selling such loans into the secondary market. By doing so, the Company is able to realize a higher yield on these loans; however, the Company also incurs interest rate risk as well as the risks associated with
nonpayments on such loans.

Construction and Land Development Loans. The Company makes loans to finance the construction of
residential and, to a limited extent, nonresidential properties. Construction loans generally are collateralized by first liens on real estate and have floating interest rates. The Company conducts periodic inspections, either directly or through an
agent, prior to approval of periodic draws on these loans. Underwriting guidelines similar to those described above are also used in the Companys construction lending activities. Construction loans involve additional risks attributable to the
fact that loan funds are advanced upon the security of a project under construction, and the project is of uncertain value prior to its completion. Because of uncertainties inherent in estimating construction costs, the market value of the completed
project and the effects of governmental regulation on real property, it can be difficult to accurately evaluate the total funds required to complete a project and the related loan to value ratio. As a result of these uncertainties, construction
lending often involves the disbursement of substantial funds with repayment dependent, in part, on the success of the ultimate project rather than the ability of a borrower or guarantor to repay the loan. If the Company is forced to foreclose on a
project prior to completion, there is no assurance that the Company will be able to recover all of the unpaid portion of the loan. In addition, the Company may be required to fund additional amounts to complete a project and may have to hold the
property for an indeterminate period of time. While the Company has underwriting procedures designed to identify what it believes to be acceptable levels of risks in construction lending, no assurance can be given that these procedures will prevent
losses from the risks described above.

Agriculture Loans. The Company provides agriculture loans for short-term crop production,
including rice, cotton, milo and corn, farm equipment financing and agriculture real estate financing. The Company evaluates agriculture borrowers primarily based on their historical profitability, level of experience in their particular agriculture
industry, overall financial capacity and the availability of secondary collateral to withstand economic and natural variations common to the industry. Because agriculture loans present a higher level of risk associated with events caused by nature,
the Company routinely makes on-site visits and inspections in order to identify and monitor such risks.

Consumer Loans. Consumer
loans made by the Company include direct A-credit automobile loans, recreational vehicle loans, boat loans, home improvement loans, home equity loans, personal loans (collateralized and uncollateralized) and deposit account
collateralized loans. The terms of these loans typically range from 12 to 120 months and vary based upon the nature of collateral and size of loan. Generally, consumer loans entail greater risk than do real estate secured loans, particularly in the
case of consumer loans that are unsecured or collateralized by rapidly depreciating assets such as automobiles. In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment for the
outstanding loan balance. The remaining deficiency often does not warrant further substantial collection efforts against the borrower beyond obtaining a deficiency judgment. In addition, consumer loan collections are dependent on the borrowers
continuing financial stability, and thus are more likely to be adversely affected by job loss, divorce, illness or personal bankruptcy. Furthermore, the application of various federal and state laws may limit the amount which can be recovered on
such loans.

The contractual maturity ranges of the 1-4 family residential, home equity, commercial and industrial, commercial mortgage,
construction and land development and agriculture portfolios and the amount of such loans with predetermined interest rates and floating rates in each maturity range as of December 31, 2008 are summarized in the following table:

Nonperforming Assets

The Company has several procedures in place to assist it in maintaining the overall quality of its loan portfolio. The Company has established underwriting guidelines to be followed by its officers and the Company
also monitors its delinquency levels for any negative or adverse trends. There can be no assurance, however, that the Companys loan portfolio will not become subject to increasing pressures from deteriorating borrower credit due to general
economic conditions.

The Company generally places a loan on nonaccrual status and ceases accruing interest when the payment of principal
or interest is delinquent for 90 days, or earlier in some cases, unless the loan is in the process of

collection and the underlying collateral fully supports the carrying value of the loan. The Company generally charges off such loans before attaining
nonaccrual status.

The Company requires appraisals on loans collateralized by real estate. With respect to potential problem loans, an
evaluation of the borrowers overall financial condition is made to determine the need, if any, for possible writedowns or appropriate additions to the allowance for credit losses.

The Companys conservative lending approach has resulted in strong asset quality. The Company had $14.4 million in nonperforming assets at
December 31, 2008 compared with $15.4 million at December 31, 2007 and $1.1 million at December 31, 2006. The nonperforming assets at December 31, 2008 consisted of ninety-eight (98) separate credits or ORE properties, of
which forty-five (45) credits were related to loans acquired in the Companys 2008 and 2007 acquisitions. If interest on nonaccrual loans had been accrued under the original loan terms, approximately $121,000, $47,000 and $30,000 would
have been recorded as income for the years ended December 31, 2008, 2007 and 2006, respectively.

The following table presents

The allowance for credit losses is a valuation 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
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.
Charge-offs occur when loans are deemed to be uncollectible.

The Company considers risk elements attributable to particular loan types or
categories in assessing the quality of individual loans. Some of the risk elements include:



| |  |  | for 1-4 family residential mortgage loans, the borrowers ability to repay the loan, including a consideration of the debt to income ratio and employment and
income stability, the loan to value ratio, and the age, condition and marketability of collateral;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | for commercial mortgage loans and multifamily residential loans, the debt service coverage ratio (income from the property in excess of operating expenses compared
to loan payment requirements),
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | operating results of the owner in the case of owner-occupied properties, the loan to value ratio, the age and condition of the collateral and the volatility
of income, property value and future operating results typical of properties of that type;
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | for agricultural real estate loans, the experience and financial capability of the borrower, projected debt service coverage of the operations of the borrower and
loan to value ratio;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | for construction and land development loans, the perceived feasibility of the project including the ability to sell developed lots or improvements constructed for
resale or ability to lease property constructed for lease, the quality and nature of contracts for presale or preleasing, if any, experience and ability of the developer and loan to value ratio;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | for commercial and industrial loans, the operating results of the commercial, industrial or professional enterprise, the borrowers business, professional and
financial ability and expertise, the specific risks and volatility of income and operating results typical for businesses in that category and the value, nature and marketability of collateral; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | for non-real estate agricultural loans, the operating results, experience and financial capability of the borrower, historical and expected market conditions and
the value, nature and marketability of collateral.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, for each category, the Company considers secondary
sources of income and the financial strength and credit history of the borrower and any guarantors.

The Company follows a loan review
program to evaluate the credit risk in the loan portfolio. Through the loan review process, the Company maintains an internal list of impaired loans which, along with the delinquency list of loans, helps management assess the overall quality of the
loan portfolio and the adequacy of the allowance for credit losses. For each impaired loan, the Company allocates a specific loan loss reserve primarily based on the value of the collateral securing the impaired loan in accordance with Statement of
Financial Accounting Standards (SFAS) No. 114, Accounting by Creditors for Impairment of a Loan, as amended.

Federal and state bank regulators also require that a bank maintain an allowance that is sufficient to absorb an estimated amount of unidentified potential losses to the portfolio based on managements perception of economic
conditions, loan portfolio growth, historical charge-off experience and exposure concentrations. This unallocated allowance is also established based on the Companys historical charge-off experience and existing general economic and business
conditions affecting the key lending areas of the Company, credit quality trends, collateral values, loan volume, concentrations and seasoning of the loan portfolio and factors associated with the Companys acquisitions. The Company then
charges to operations a provision for credit losses to maintain the allowance for credit losses at an adequate level determined by the foregoing methodology.

At December 31, 2008, the allowance for credit losses totaled $37.0 million, or 1.04% of total loans. At December 31, 2007, the allowance aggregated $32.5 million or 1.04% of total loans and at
December 31, 2006, the allowance was $24.0 million or 1.10% of total loans.

|(1) | In 2006, the Company revised its allowance methodology to provide for more specific allocation of its reserves. The revised methodology did not have a material impact on the
Companys determination of the overall allowance for credit losses.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Company believes that the allowance for credit
losses at December 31, 2008 is adequate to cover losses inherent in the loan portfolio as of such date. There can be no assurance, however, that the Company will not sustain losses in future periods, which could be substantial in relation to
the size of the allowance at December 31, 2008.

Securities

The Company uses its securities portfolio as a source of income, as a source of liquidity for cash requirements and to manage interest rate risk. At December 31, 2008, the carrying amount of investment securities
totaled $4.160 billion, an increase of $2.30 billion or 124.0% compared with $1.858 billion at December 31, 2007. The increase in securities was primarily due to the purchase of new securities with the funds acquired in the Franklin Bank
acquisition. Securities increased to $1.858 billion at December 31, 2007 from $1.590 billion at December 31, 2006, an increase of $267.3 million or 16.8%. At December 31, 2008, securities represented 45.9% of total assets compared
with 29.1% of total assets at December 31, 2007.

##### Table of Contents

At the date of purchase, the Company is required to classify debt and equity securities into one of three
categories: held-to-maturity, trading or available-for-sale. At each reporting date, the appropriateness of the classification is reassessed. Investments in debt securities are classified as held-to-maturity and measured at amortized cost in the
financial statements only if management has the positive intent and ability to hold those securities to maturity. Securities that are bought and held principally for the purpose of selling them in the near term are classified as trading and measured
at fair value in the financial statements with unrealized gains and losses included in earnings. Investments not classified as either held-to-maturity or trading are classified as available-for-sale and measured at fair value in the financial
statements with unrealized gains and losses reported, net of tax, in a separate component of shareholders equity until realized.

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):

The following table summarizes the contractual maturity of securities and their weighted average
yields as of December 31, 2008. The contractual maturity of a mortgage-backed security is the date at which the last underlying mortgage matures. Available-for-sale securities are shown at fair value and held-to-maturity securities are shown at
amortized cost. Other securities are included in the corporate debt securities category. For purposes of the table below, tax-exempt states and political subdivisions are calculated on a tax equivalent basis. The QZAB bond is not calculated on a tax
equivalent basis and it generates a tax credit of 7.18%, which is included in gross income.

##### Table of Contents

The contractual maturity of mortgage-backed securities and collateralized mortgage obligations is not a
reliable indicator of their expected life because borrowers have the right to prepay their obligations at any time. Mortgage-backed securities monthly pay downs cause the average lives of the securities to be much different than their stated lives.
The weighted average life of the Companys complete portfolio is 2.9 years with an effective duration of 3.0 years at December 31, 2008.

At December 31, 2008 and 2007, the Company did not own securities of any one issuer (other than the U.S. government and its agencies) for which aggregate adjusted cost exceeded 10% of the consolidated shareholders equity at such
respective dates.

The average yield of the securities portfolio was 4.90% in 2008 compared with 4.84% in 2007 and 4.51% in 2006. The 6
basis point increase in 2008 was primarily due to the Company reinvesting funds at higher rates in 2008 compared to 2007. The overall growth in the securities portfolio over the comparable periods was primarily funded by deposit growth and
securities acquired in acquisitions.

The following table summarizes the carrying value by classification of securities as of the dates
shown:

As part of its regular quarterly review for impairment of marketable securities, the Company
recognized an other-than-temporary impairment charge of $14.0 million pre-tax on Fannie Mae and Freddie Mac government sponsored, investment grade perpetual callable preferred securities during the year ended December 31, 2008 and $10.0 million
during the year ended December 31, 2007. The other-than-temporary impairment charges were

recorded on six perpetual preferred stock issues classified as available-for-sale investment securities, which are included in the tables above as 70%
non-taxable preferred stock, with a total book value of $24.0 million prior to recognition of the initial 2007 impairment charge and no book value after the 2008 impairment charge. The Company reclassified the unrealized mark-to-market loss on these
investment grade securities to an other-than-temporary impairment charge because of the recent significant decline in the market value of these securities and because management believes it is unlikely that these securities will recover their
original book value within a reasonable amount of time. Both Fannie Mae and Freddie Mac securities were investment grade at the time of purchase.

Management believes that the gross unrealized losses in the Companys securities portfolio at December 31, 2008 were primarily due to interest rate increases. Because the decline in market value of such securities was primarily
attributable to changes in interest rates and not credit quality, and because the Company has the ability and intent to hold such securities until a recovery of fair value, which may be at maturity, the Company does not consider such securities to
be other-than-temporarily impaired at December 31, 2008.

Mortgage-backed securities are securities that have been developed by
pooling a number of real estate mortgages and which are principally issued by federal agencies such as Government National Mortgage Association (Ginnie Mae), Fannie Mae and Freddie Mac. These securities are deemed to have high credit ratings, and
minimum regular monthly cash flows of principal and interest are guaranteed by the issuing agencies.

Unlike U.S. Treasury and U.S.
government agency securities, which have a lump sum payment at maturity, mortgage-backed securities provide cash flows from regular principal and interest payments and principal prepayments throughout the lives of the securities. Mortgage-backed
securities which are purchased at a premium will generally suffer decreasing net yields as interest rates drop because home owners tend to refinance their mortgages. Thus, the premium paid must be amortized over a shorter period. Therefore, these
securities purchased at a discount will obtain higher net yields in a decreasing interest rate environment. As interest rates rise, the opposite will generally be true. During a period of increasing interest rates, fixed rate mortgage-backed
securities do not tend to experience heavy prepayments of principal and consequently, the average life of this security will be lengthened. If interest rates begin to fall, prepayments will increase, thereby shortening the estimated life of this
security. At December 31, 2008, 68.8% of the mortgage-backed securities held by the Company had contractual final maturities of more than ten years with a weighted average life of 3.34 years.

Collateralized mortgage obligations (CMOs) are bonds that are backed by pools of mortgages. The pools can be Ginnie Mae, Fannie Mae or
Freddie Mac pools or they can be private-label pools. CMOs are designed so that the mortgage collateral will generate a cash flow sufficient to provide for the timely repayment of the bonds. The mortgage collateral pool can be structured to
accommodate various desired bond repayment schedules, provided that the collateral cash flow is adequate to meet scheduled bond payments. This is accomplished by dividing the bonds into classes to which payments on the underlying mortgage pools are
allocated in different order. The bonds cash flow, for example, can be dedicated to one class of bondholders at a time, thereby increasing call protection to bondholders. In private-label CMOs, losses on underlying mortgages are directed to
the most junior of all classes and then to the classes above in order of increasing seniority, which means that the senior classes have enough credit protection to be given the highest credit rating by the rating agencies.

Deposits

The Companys lending and investing
activities are primarily funded by deposits. The Company offers a variety of deposit accounts having a wide range of interest rates and terms including demand, savings, money market and time accounts. The Company relies primarily on competitive

respectively, in junior subordinated debentures issued to the Companys unconsolidated subsidiary trusts. The decrease of $20.6 million was due to the Companys redemption of $10.3 million in junior subordinated debentures issued to each

investing the proceeds in the Companys junior subordinated debentures. The preferred trust securities of each trust represent preferred beneficial interests in the assets of the respective trusts and are subject to mandatory redemption upon
payment of the junior subordinated debentures held by the trust. The common securities of each trust are wholly owned by the Company. Each trusts ability to pay amounts due on the trust preferred securities is solely dependent upon the Company
making payment on the related junior subordinated debentures. The debentures, which are the only assets of each trust, are subordinate and junior in right of payment to all of the Companys present and future senior indebtedness. The Company
has fully and unconditionally guaranteed each trusts obligations under the trust securities issued by such trust to the extent not paid or made by each trust, provided such trust has funds available for such obligations.

Under the provisions of each issue of the debentures, the Company has the right to defer payment of interest on the debentures at any time, or from time
to time, for periods not exceeding five years. If interest payments on either issue of the debentures are deferred, the distributions on the applicable trust preferred securities and common securities will also be deferred.

Interest Rate Sensitivity and Market Risk

The
Companys asset liability and funds management policy provides management with the necessary guidelines for effective funds management, and the Company has established a measurement system for monitoring its net interest rate sensitivity
position. The Company manages its sensitivity position within established guidelines.

As a financial institution, the Companys
primary component of market risk is interest rate volatility. Fluctuations in interest rates will ultimately impact both the level of income and expense recorded on most of the Companys assets and liabilities, and the market value of all
interest-earning assets and interest-bearing liabilities, other than those which have a short term to maturity. Interest rate risk is the potential of economic losses due to future interest rate changes. These economic losses can be reflected as a
loss of future net interest income and/or a loss of current fair market values. The objective is to measure the effect on net interest income and to adjust the balance sheet to minimize the inherent risk while at the same time maximizing income.

The Company manages its exposure to interest rates by structuring its balance sheet in the ordinary course of business. The Company does
not enter into instruments such as leveraged derivatives, interest rate swaps, financial options, financial future contracts or forward delivery contracts for the purpose of reducing interest rate risk. Based upon the nature of the Companys
operations, the Company is not subject to foreign exchange or commodity price risk. The Company does not own any trading assets.

The
Companys exposure to interest rate risk is managed by the Asset Liability Committee (ALCO), which is composed of senior officers of the Company, in accordance with policies approved by the Companys Board of Directors. The
ALCO formulates strategies based on appropriate levels of interest rate risk. In determining the appropriate level of interest rate risk, the ALCO considers the impact on earnings and capital of the current outlook on interest rates, potential
changes in interest rates, regional economies, liquidity, business strategies and other factors. The ALCO meets regularly to review, among other things, the sensitivity of assets and liabilities to interest rate changes, the book and market values
of assets and liabilities, unrealized gains and losses, purchase and sale activities, commitments to originate loans and the maturities of investments and borrowings. Additionally, the ALCO reviews liquidity, cash flow flexibility, maturities of
deposits and consumer

and commercial deposit activity. Management uses two methodologies to manage interest rate risk: (1) an analysis of relationships between
interest-earning assets and interest-bearing liabilities; and (2) an interest rate shock simulation model. The Company has traditionally managed its business to reduce its overall exposure to changes in interest rates.

An interest rate sensitive asset or liability is one that, within a defined time period, either matures or experiences an interest rate change in line
with general market interest rates. The management of interest rate risk is performed by analyzing the maturity and repricing relationships between interest-earning assets and interest-bearing liabilities at specific points in time (GAP)
and by analyzing the effects of interest rate changes on net interest income over specific periods of time by projecting the performance of the mix of assets and liabilities in varied interest rate environments. Interest rate sensitivity reflects
the potential effect on net interest income of a movement in interest rates. A company is considered to be asset sensitive, or having a positive GAP, when the amount of its interest-earning assets maturing or repricing within a given period exceeds
the amount of its interest-bearing liabilities also maturing or repricing within that time period. Conversely, a company is considered to be liability sensitive, or having a negative GAP, when the amount of its interest-bearing liabilities maturing
or repricing within a given period exceeds the amount of its interest-earning assets also maturing or repricing within that time period. During a period of rising interest rates, a negative GAP would tend to affect net interest income adversely,
while a positive GAP would tend to result in an increase in net interest income. During a period of falling interest rates, a negative GAP would tend to result in an increase in net interest income, while a positive GAP would tend to affect net
interest income adversely.

The following table sets forth the Companys interest rate sensitivity analysis at December 31, 2008:

While the GAP position is a useful tool in measuring interest rate risk and contributes toward
effective asset and liability management, it is difficult to predict the effect of changing interest rates solely on that measure, without accounting for alterations in the maturity or repricing characteristics of the balance sheet that occur during
changes in market interest rates. For example, the GAP position reflects only the prepayment assumptions pertaining to the current rate environment. Assets tend to prepay more rapidly during periods of declining interest rates than during periods of
rising interest rates. Because of this and other risk factors not contemplated by the

GAP position, an institution could have a matched GAP position in the current rate environment and still have its net interest income exposed to increased
rate risk. Additionally, the Company had $1.523 billion in noninterest-bearing deposits at December 31, 2008 that are not reflected in the table above and are not directly impacted by interest rate changes.

The assumptions used are inherently uncertain and, as a result, the model cannot precisely measure future net interest income or precisely predict the
impact of fluctuations in market interest rates on net interest income. Actual results will differ from the models simulated results due to timing, magnitude and frequency of interest rate changes as well as changes in market conditions and
the application and timing of various management strategies.

In addition to GAP analysis, the Company uses an interest rate risk
simulation model and shock analysis to test the interest rate sensitivity of net interest income and the balance sheet, respectively. Contractual maturities and repricing opportunities of loans are incorporated in the model as are prepayment
assumptions, maturity data and call options within the investment portfolio. Assumptions based on past experience are incorporated into the model for nonmaturity deposit accounts. The assumptions used are inherently uncertain and, as a result, the
model cannot precisely measure future net interest income or precisely predict the impact of fluctuations in market interest rates on net interest income. Actual results will differ from the models simulated results due to timing, magnitude
and frequency of interest rate changes as well as changes in market conditions and the application and timing of various management strategies.

The Companys simulation analysis as of December 31, 2008 estimates a percentage of change in these metrics from the stable rate base scenario versus alternative scenarios of rising and falling market interest rates by
instantaneously shocking a static balance sheet. The following table summarizes the simulated change in net interest income over a 12-month horizon in the event of an immediate and sustained change in interest rates:

The results are primarily due to behavior of demand, money market and savings deposits during such
rate fluctuations. The Company has found that historically, interest rates on these deposits change more slowly than changes in the discount and federal funds rates. This assumption is incorporated into the simulation model and is generally not
fully reflected in a GAP analysis.

Liquidity

Liquidity involves the Companys ability to raise funds to support asset growth and acquisitions 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 and manage unexpected events. During the two years ended December 31, 2008, the Companys liquidity needs have primarily been met by growth in core deposits, security and loan maturities and amortizing investment and
loan portfolios. Although access to purchased funds from correspondent banks and over-night advances from Federal Home Loan Bank-Dallas 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 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. The Company is focused on increasing loans with average loans growing 5.1% for the year ended December 31, 2008 compared with the year ended December 31, 2007. The
increase in loans has primarily been funded by an increase in deposits through acquisitions and internal growth. The Company invests excess deposits in government backed securities until the funds are needed to fund loan growth. The Companys
securities portfolio has a weighted average life of 2.9 years and an effective duration of 3.0 years at December 31, 2008.

As of December
31, 2008, the Company had outstanding $685.7 million in commitments to extend credit and $28.3 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.

As
of December 31, 2008, the Company had cash and cash equivalents of $228.6 million compared with $371.1 million at December 31, 2007. The decrease was mainly due to a decrease in federal funds sold of $176.5 million and an increase in cash and due
from banks of $38.4 million due to the Franklin acquisition.

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 expiring by period as of December 31, 2008 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:

Standby Letters of Credit.Standby letters of credit are written conditional commitments
issued by the Company to guarantee the performance of a customer to a third party. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment.
The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount of the commitment. If the commitment is funded, the Company would be entitled to seek recovery from the customer. The
Companys policies generally require that standby letter of credit arrangements contain security and debt covenants similar to those contained in loan agreements.

Commitments to Extend Credit.The Company enters into contractual commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes.
Substantially all of the Companys commitments to extend credit are contingent upon customers maintaining specific credit standards at the time of loan funding. The Company minimizes its exposure to loss under these

commitments by subjecting them to credit approval and monitoring procedures. Management assesses the credit risk associated with certain commitments to
extend credit in determining the level of the allowance for credit losses.

Capital Resources

Capital management consists of providing equity to support the Companys current and future operations. The Company is subject to capital adequacy
requirements imposed by the Federal Reserve Board and the Bank is subject to capital adequacy requirements imposed by the FDIC. Both the Federal Reserve Board and the FDIC have adopted risk-based capital requirements for assessing bank holding
company and bank capital adequacy. These standards define capital and establish minimum capital requirements in relation to assets and off-balance sheet exposure, adjusted for credit risk. The risk-based capital standards currently in effect are
designed to make regulatory capital requirements more sensitive to differences in risk profiles among bank holding companies and banks, to account for off-balance sheet exposure and to minimize disincentives for holding liquid assets. Assets and
off-balance sheet items are assigned to broad risk categories, each with appropriate relative risk weights. The resulting capital ratios represent capital as a percentage of total risk-weighted assets and off-balance sheet items.

The risk-based capital standards issued by the Federal Reserve Board require all bank holding companies to have Tier 1 capital of at least
4.0% and total risk-based capital (Tier 1 and Tier 2) of at least 8.0% of total risk-weighted tangible assets. Tier 1 capital generally includes common shareholders equity and qualifying perpetual preferred stock
together with related surpluses and retained earnings, less deductions for goodwill and various other intangibles. Tier 2 capital may consist of a limited amount of intermediate-term preferred stock, a limited amount of term subordinated
debt, certain hybrid capital instruments and other debt securities, perpetual preferred stock not qualifying as Tier 1 capital, and a limited amount of the general valuation allowance for loan losses. The sum of Tier 1 capital and Tier 2 capital is
total risk-based capital.

The Federal Reserve Board has also adopted guidelines which supplement the risk-based capital
guidelines with a minimum ratio of Tier 1 capital to average total consolidated tangible assets, or leverage ratio, of 3.0% for institutions with well diversified risk, including no undue interest rate exposure; excellent asset quality;
high liquidity; good earnings; and that are generally considered to be strong banking organizations, rated composite 1 under applicable federal guidelines, and that are not experiencing or anticipating significant growth. Other banking organizations
are required to maintain a leverage ratio of at least 4.0%. These rules further provide that banking organizations experiencing internal growth or making acquisitions will be expected to maintain capital positions substantially above the minimum
supervisory levels and comparable to peer group averages, without significant reliance on intangible assets.

Pursuant to FDICIA, each
federal banking agency revised its risk-based capital standards to ensure that those standards take adequate account of interest rate risk, concentration of credit risk and the risks of nontraditional activities, as well as reflect the actual
performance and expected risk of loss on multifamily mortgages. The Bank is subject to capital adequacy guidelines of the FDIC that are substantially similar to the Federal Reserve Boards guidelines. Also pursuant to FDICIA, the FDIC has
promulgated regulations setting the levels at which an insured institution such as the Bank would be considered well-capitalized, adequately capitalized, undercapitalized, significantly
undercapitalized and critically undercapitalized. Under the FDICs regulations, the Bank is classified well-capitalized for purposes of prompt corrective action.

Total shareholders equity increased to $1.255 billion at December 31, 2008 compared
with $1.127 billion at December 31, 2007, an increase of $127.7 million or 11.3%. This increase was primarily the result of net income of $84.5 million and $56.1 million in Common Stock issued in connection with the 1stChoice acquisition, partially offset by dividends paid on the Common Stock of $23.4 million. During 2007, shareholders equity increased by $463.0
million or 69.7% compared with $664.4 million at December 31, 2006, primarily due to net income of $84.2 million and $389.4 million in Common Stock issued in connection with the TXUI and Navasota acquisitions, partially offset by dividends paid
on the Common Stock of $20.3 million.

The trust preferred securities issued by the Companys subsidiary trusts are currently included in the Companys Tier 1 capital for regulatory purposes. On March 1, 2005, the Federal Reserve Board
adopted final rules that continue to allow trust preferred securities to be included in Tier 1 capital, subject to stricter quantitative and qualitative limits. Currently, trust preferred securities and qualifying perpetual preferred stock are
limited in the aggregate to no more than 25% of a bank holding companys core capital elements. The new rule amends the existing limit by providing that restricted core capital elements (including trust preferred securities and qualifying
perpetual preferred stock) can be no more than 25% of core capital, net of goodwill and associated deferred tax liability. Because the 25% limit currently is calculated without deducting goodwill, the final rule reduces the amount of trust preferred
securities that the Company can include in Tier 1 capital. The amount of such excess trust preferred securities are includable in Tier 2 capital. The new quantitative limits will be fully effective March 31, 2009.

Assuming these final rules were effective at December 31, 2008, all trust preferred securities would count as Tier 1 capital. If applicable, the
excess amount of trust preferred securities may be included in Tier 2 capital. Assuming these final rules were effective at December 31, 2008, the Companys consolidated capital ratios would have been unchanged.

Each of the trusts issuing the trust preferred securities holds junior subordinated debentures the Company issued with a 30-year maturity. The final
rules provide that in the last five years before the junior subordinated debentures mature, the associated trust preferred securities will be excluded from Tier 1 capital and included in Tier 2 capital. In addition, the trust preferred securities
during this five-year period would be amortized out of Tier 2 capital by one-fifth each year and excluded from Tier 2 capital completely during the year prior to maturity of the debentures.

Officer concluded that the Companys disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the Exchange Act)) 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 defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended December 31, 2008, that have materially affected, or are reasonably likely to materially affect, the
Companys internal control over financial reporting.

MANAGEMENTS REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting. The Companys
internal control over financial reporting is a process designed under the supervision of the Companys Chief Executive Officer and Chief Financial Officer to provide reasonable assurance regarding the reliability of financial reporting and the
preparation of the Companys financial statements for external purposes in accordance with generally accepted accounting principles.

As of December 31, 2008, management assessed the effectiveness of the Companys internal control over financial reporting based on the criteria for effective internal control over financial reporting established in Internal
ControlIntegrated Framework, issued by the Committee of Sponsoring Organizations (COSO) of the Treadway Commission. This assessment included controls over the preparation of the schedules equivalent to the basic financial
statements in accordance with the instructions for the Consolidated Financial Statements for Bank Holding Companies (Form FR Y-9C) to meet the reporting requirements of Section 112 of the Federal Deposit Insurance Corporation Improvement Act.

The Company assumed deposits and acquired certain assets from the FDIC, in its capacity as receiver of Franklin Bank, on November 7, 2008.
Such balances constituted approximately 22% of total assets and 27% of total deposits of the consolidated financial statement amounts as of December 31, 2008. As permitted by the Securities and Exchange Commission, management excluded the assumed
deposits and liabilities and acquired assets from its assessment of the effectiveness of the Companys internal control over financial reporting as of December 31, 2008. Based on the assessment, which excluded the Franklin acquisition, as
described above, management determined that the Company maintained effective internal control over financial reporting as of December 31, 2008.

Deloitte & Touche LLP the independent registered public accounting firm that audited the consolidated financial statements of the Company included in this Annual Report on Form 10-K, has issued an attestation
report on the Companys internal control over financial reporting as of December 31, 2008. The report is included in this Item under the heading Report of Independent Registered Public Accounting Firm.

Compliance with Designated Laws and Regulations

Management is also responsible for ensuring compliance with the federal laws and regulations concerning loans to insiders and the federal and state laws and regulations concerning dividend restrictions, both of which
are designated by the Federal Deposit Insurance Corporation (FDIC) as safety and soundness laws and regulations.

Management assessed its
compliance with the designated safety and soundness laws and regulations and has maintained records of its determinations and assessments as required by the FDIC. Based on this assessment, management believes that the Company has complied, in all
material respects, with the designated safety and soundness laws and regulations for the year ended December 31, 2008.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Prosperity Bancshares, Inc.

Houston, Texas

We have audited the internal control over financial reporting of Prosperity Bancshares, Inc.
and subsidiaries (the Bank) as of December 31, 2008, based on criteria established in Internal ControlIntegrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission. Because
managements assessment and our audit were conducted to meet the reporting requirements of Section 112 of the Federal Deposit Insurance Corporation Improvement Act (FDICIA), managements assessment and our audit of the Banks
internal control over financial reporting included controls over the preparation of the schedules equivalent to the basic financial statements in accordance with the instructions for the Consolidated Financial Statements for Bank Holding Companies
(Form FR Y-9C). As described in Managements Report on Internal Control over Financial Reporting, management excluded from its assessment the internal control over financial reporting related to the assumption of deposits and acquisition of
certain assets from the FDIC, in its capacity as receiver of Franklin Bank, on November 7, 2008. Such balances constituted approximately 22% of total assets and 27% of total deposits of the consolidated financial statement amounts as of December 31,
2008. Accordingly, our audit did not include the internal control over financial reporting related to the assumed deposits and the acquired assets. The Banks management is responsible for maintaining effective internal control over financial
reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Managements Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on
the Banks internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of
the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material
respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the
assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a process designed by, or under the supervision of, the companys principal executive
and principal financial officers, or persons performing similar functions, and effected by the companys board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and
the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies and procedures that (1) pertain to the
maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation
of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and
(3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override
of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to
the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Bank maintained, in all material respects, effective internal control over financial reporting as of December 31, 2008, based on the criteria established inInternal ControlIntegrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

Prosperity Bancshares, Inc.

Houston, Texas

We have audited the accompanying consolidated balance sheets of Prosperity Bancshares Inc. and subsidiaries (the Bank) as of December 31, 2008 and 2007, and the related consolidated statements of income, changes in
shareholders equity, and cash flows for each of the three years in the period ended December 31, 2008. These financial statements are the responsibility of the Banks management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial
statements present fairly, in all material respects, the financial position of Prosperity Bancshares, Inc. and subsidiaries at December 31, 2008 and 2007, and the results of their operations and their cash flows for each of the three years in
the period ended December 31, 2008, in conformity with accounting principles generally accepted in the United States of America.

We
have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Banks internal control over financial reporting as of December 31, 2008, based on the criteria established in
Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 2, 2009 expressed an unqualified opinion on the Banks internal control over
financial reporting.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES

Nature of OperationsProsperity Bancshares, Inc.® (Bancshares) and its subsidiaries, Prosperity Holdings of Delaware, LLC (Holdings) and Prosperity Bank® (the Bank, and
together with Bancshares and Holdings, collectively referred to as the Company) provide retail and commercial banking services. The Company operates its business as one domestic segment.

The Bank operates one hundred sixty-eight (168) full-service banking locations; with fifty-three (53) in the Greater Houston Consolidated
Metropolitan Statistical Area (CMSA), twenty-seven (27) in the South Texas area including Corpus Christi and Victoria, forty-three (43) in the Central Texas area including Austin and Bryan/College Station, twenty-one
(21) in East Texas and twenty-four (24) in the Dallas/Fort Worth, Texas area.

Principles of ConsolidationThe
consolidated financial statements include the accounts of Bancshares and its wholly owned subsidiaries. All intercompany transactions have been eliminated in consolidation. The accounting and reporting policies of the Company conform to accounting
principles generally accepted in the United States of America (GAAP) and the prevailing practices within the banking industry. A summary of significant accounting and reporting policies is as follows:

Use of EstimatesThe preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could
differ from these estimates.

SecuritiesSecurities held to maturity are carried at cost, adjusted for the amortization of
premiums and the accretion of discounts. Management has the positive intent and the Company has the ability to hold these assets as long-term securities until their estimated maturities.

Securities available for sale are carried at fair value. Unrealized gains and losses are excluded from earnings and reported, net of tax, as a separate
component of shareholders equity until realized. Securities within the available for sale portfolio may be used as part of the Companys asset/liability strategy and may be sold in response to changes in interest risk, prepayment risk or
other similar economic factors.

Declines in the fair value of individual held to maturity and available for sale securities below their
cost that are other than temporary would result in write-downs of the individual securities to their fair value. The related write-downs would be included in earnings as realized losses.

Premiums and discounts are amortized and accreted to operations using the level-yield method of accounting, adjusted for prepayments as applicable. The
specific identification method of accounting is used to compute gains or losses on the sales of these assets. Interest earned on these assets is included in interest income.

Loans Held for InvestmentLoans are stated at the principal amount outstanding, net of unearned discount and fees. Unearned discount relates
principally to consumer installment loans. The related interest income for multipayment loans is recognized principally by the simple interest method; for single payment loans, such income is recognized using the straight-line method.

Nonrefundable Fees and Costs Associated with Lending ActivitiesLoan origination fees in excess of the associated costs are recognized over
the life of the related loan as an adjustment to yield using the interest method.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



Loan commitment fees and loan origination costs are deferred, except for certain retrospectively
determined fees, and recognized as an adjustment of yield by the interest method over the related loan life or, if the commitment expires unexercised, recognized in income upon expiration of the commitment.

Nonperforming and Past Due LoansIncluded in the nonperforming loan category are loans which have been categorized by management as
nonaccrual because collection of interest is doubtful and loans which have been restructured to provide a reduction in the interest rate or a deferral of interest or principal payments. When the payment of principal or interest on a loan is
delinquent for 90 days, or earlier in some cases, the loan is placed on nonaccrual status unless the loan is in the process of collection and the underlying collateral fully supports the carrying value of the loan. If the decision is made to
continue accruing interest on the loan, periodic reviews are made to confirm the accruing status of the loan. When a loan is placed on nonaccrual status, interest accrued during the current year prior to the judgment of uncollectibility is charged
to operations. Interest accrued during prior periods is charged to allowance for credit losses. Any payments received on nonaccrual loans are applied first to outstanding loan amounts and next to the recovery of charged-off loan amounts. Any excess
is treated as recovery of lost interest.

Restructured loans are those loans on which concessions in terms have been granted because of a
borrowers financial difficulty. Interest is generally accrued on such loans in accordance with the new terms.

Allowance for
Credit LossesThe allowance for credit losses is a valuation allowance available for losses incurred on loans. All losses are charged to the allowance when the loss actually occurs or when a determination is made that such a loss is
probable. Recoveries are credited to the allowance at the time of recovery.

Throughout the year, management estimates the probable level
of losses to determine whether the allowance for credit losses is adequate to absorb losses inherent in the loan portfolio. Based on these estimates, an amount is charged to the provision for credit losses and credited to the allowance for credit
losses in order to adjust the allowance to a level determined to be adequate to absorb losses.

In making its evaluation of the adequacy of
the allowance for credit losses, 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.

Estimates of credit losses involve an exercise of judgment. While it is possible that in the
short term the Company may sustain losses which are substantial in relation to the allowance for credit losses, it is the judgment of management that the allowance for credit losses reflected in the consolidated balance sheets is adequate to absorb
probable losses that exist in the current loan portfolio.

Statement of Financial Accounting Standards (SFAS) No. 114,
Accounting by Creditors for Impairment of a Loan, as amended by SFAS No. 118, Accounting by Creditors for Impairment of a LoanIncome Recognition and Disclosure applies to all impaired loans, with the exception of groups of
smaller-balance homogeneous loans that are collectively evaluated for impairment. A loan is defined as impaired by SFAS No. 114 if, based on current information and events, it is probable that a creditor will be unable to collect all amounts
due, both interest and principal, according to the contractual terms of the loan agreement. Specifically, SFAS No. 114 requires that the allowance for credit losses related to impaired loans be determined based on the difference of carrying
value of loans and the present value of expected cash flows discounted at the loans effective interest rate or, as a practical expedient, the loans observable market price or the fair value of the collateral if the loan is

collateral dependent. At December 31, 2008, the Company had $2.1 million in nonaccrual loans, $7.6 million in 90 days or more past due loans and no
restructured loans. At December 31, 2007, the Company had $1.0 million in nonaccrual loans, $4.1 million in 90 days or more past due loans and no restructured loans.

Interest revenue received on impaired loans is either applied against principal or realized as interest revenue, according to managements judgment as to the collectibility of principal.

Premises and EquipmentPremises and equipment are carried at cost less accumulated depreciation. Depreciation expense is computed principally
using the straight-line method over the estimated useful lives of the assets which range from three to 30 years. Leasehold improvements are amortized using the straight-line method over the periods of the leases or the estimated useful lives,
whichever is shorter.

GoodwillGoodwill is annually assessed for impairment or when events or changes in circumstances
indicate that the carrying amount of the asset may not be recoverable. The Company bases its evaluation on such impairment factors as the nature of the assets, the future economic benefit of the assets, any historical or future profitability
measurements, as well as other external market conditions or factors that may be present.

Amortization of Core Deposit
IntangiblesCore deposit intangibles are amortized using an accelerated amortization method over an 8 to 10 year period.

Income TaxesBancshares files a consolidated federal income tax return. The Bank computes federal income taxes as if it filed a separate return and remits to, or is reimbursed by, Bancshares based on the portion of taxes
currently due or refundable.

Deferred tax assets and liabilities are recognized for the estimated tax consequences attributable to
differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis.

Stock-Based Compensation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. This model requires the input of subjective assumptions (see note 15).

Cash and Cash EquivalentsFor purposes of reporting cash flows, cash and cash equivalents include cash and due from banks as well as federal
funds sold that mature in three days or less.

Earnings Per ShareSFAS No. 128, Earnings Per Share, requires
presentation of basic and diluted earnings per share. Basic earnings per share has been computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding for the reporting period. Diluted
earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. Net income per common share for all periods presented has been calculated in
accordance with SFAS 128. Outstanding stock options issued by the Company represent the only dilutive effect reflected in diluted weighted average shares.

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 exercisable at December 31, 2008, 2007 and 2006 that would have had an anti-dilutive effect on the above computation.

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 is effective for the Company beginning 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.

SFAS No. 157, Fair Value Measurements.SFAS 157 defines fair value, establishes a framework for measuring fair value in
generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS 157 was effective for the Company on January 1, 2008 and its adoption did not have a significant impact on the Companys financial
statements. The implementation of SFAS 157 resulted in expanded disclosures about assets and liabilities measured at fair value as discussed in Note 8.

SFAS No. 159, The Fair Value Option for Financial Assets and Financial
LiabilitiesIncluding an amendment of FASB Statement No. 115.SFAS 159 permits entities to choose to measure eligible items at fair value at specified election dates. Unrealized gains and losses on items for which the fair
value option has been elected are reported in earnings at each subsequent reporting date. The fair value option (i) may be applied instrument by instrument, with certain exceptions, (ii) is irrevocable (unless a new election date occurs)
and (iii) is applied only to entire instruments and not to portions of instruments. The Company adopted SFAS No. 159 effective January 1, 2008. The Company elected not to measure any eligible items using the fair value option in
accordance with SFAS 159. Accordingly, SFAS 159 did not have any impact on the Companys financial statements.

SFAS No. 160, Noncontrolling Interest in Consolidated Financial Statements, an amendment of ARB Statement No. 51.SFAS 160 amends Accounting Research Bulletin (ARB) No. 51, Consolidated
Financial Statements, to establish accounting and reporting standards for the non-controlling interest in a subsidiary and for the deconsolidation of a subsidiary. SFAS 160 clarifies that a non-controlling interest in a subsidiary, which
is sometimes referred to as minority interest, is an ownership interest in the consolidated entity that should be reported as a component of equity in the consolidated financial statements. Among other requirements, SFAS 160 requires
consolidated net income to be reported at amounts that include the amounts attributable to both the parent and the non-controlling interest. It also requires disclosure, on the face of the consolidated income statement, of the amounts of
consolidated net income attributable to the parent and to the non-controlling interest. SFAS 160 was effective for the Company on January 1, 2009 and did not have a significant impact on the Companys financial statements.

Financial Accounting Standards Board Staff Positions and Interpretations

FASB Staff Position (FSP) No. 157-2.FSP 157-2 delays the effective date of SFAS 157,Fair Value Measurements, for nonfinancial assets and nonfinancial liabilities, except for items that are
recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). The delay is intended to allow the FASB and constituents additional time to consider the effect of various implementation issues that have
arisen, or that may arise, from the application of SFAS 157. This FSP defers the effective date of SFAS 157 to fiscal years beginning after November 15, 2008, and interim periods within those fiscal years for items within the scope of this FSP.
FSP 157-2 was effective for the Company on January 1, 2009 and did not have a significant impact on the Companys financial statements.

FASB Staff Position No. 157-3. On October 10, 2008, the FASB issued FASB Staff Position 157- 3 (FSP 157-3) Determining the Fair Value of a Financial Asset When the Market for That Asset Is Not Active. FSP
157-3 applies to financial assets within the scope of SFAS 157. FSP 157-3 clarifies the application of SFAS 157 in a market that is not active and provides an example to illustrate key considerations in determining the fair value of a financial
asset when the market for that financial asset is not active. In situations in which there is little, if any, market activity for an asset at the measurement date, the fair value measurement objective remains the same, that is, the price that would
be received by the holder of the financial asset in an orderly transaction (an exit price notion) that is not a forced liquidation or distressed sale at the measurement date. Additionally, in determining fair value for a financial asset, the use of
a reporting entitys own assumptions about future cash flows and appropriately risk-adjusted discount rates is acceptable when relevant observable inputs are not available. Broker (or pricing service) quotes may be an appropriate input when
measuring fair value, but they are not necessarily determinative if an active market does not exist for the financial asset. FSP 157-3 was effective for the Company on September 30, 2008 and did not have a significant impact on the
Companys financial statements.

Emerging Issues Task Force Issues

In January 2009, the FASB issued FSP EITF 99-20-1 (EITF 99-20-1), Amendments to the Impairment Guidance of EITF Issue No. 99-20,which
revises the other-than-temporary-impairment (OTTI) guidance on beneficial interests in securitized financial assets that are within the scope of EITF Issue 99-20, Recognition of Interest Income and Impairment on Purchased Beneficial
Interests and Beneficial Interests That Continue to Be Held by a Transferor in Securitized Financial Assets. EITF 99-20-1 amends Issue 99-20 to more closely align its OTTI guidance with paragraph 16 of FASB Statement No. 115, Accounting for
Certain Investments in Debt and Equity Securities,by (1) removing the notion of a market participant and (2) inserting a probable concept related to the estimation of a beneficial interests cash flows. EITF 99-20-1
is effective prospectively for interim and annual periods ending after December 15, 2008. Retrospective application of this FSP is prohibited. The adoption of this guidance did not have a material effect on the Companys financial condition,
results of operations or cash flows.

Emerging Issues Task Force (EITF) Issue No. 06-4, Accounting for Deferred
Compensation and Postretirement Benefit Aspects of Endorsement Split Dollar Life Insurance Arrangements.EITF 06-4 requires the recognition of a liability and related compensation expense for endorsement split-dollar life insurance
policies that provide a benefit to an employee that extends to post-retirement periods. Under EITF 06-4, life insurance policies purchased for the purpose of providing such benefits do not effectively settle an entitys obligation to the
employee. Accordingly, the entity must recognize a liability and related compensation expense during the employees active service period based on the future cost of insurance to be incurred during the employees retirement. If the entity
has agreed to provide the employee with a death benefit, then the liability for the future death benefit should be recognized by following the guidance in SFAS 106, Employers Accounting for Postretirement Benefits Other Than
Pensions. The Company adopted EITF 06-4 effective as of January 1, 2008 as a change in accounting principle through a cumulative-effect adjustment to retained earnings. The amount of the adjustment reduced retained earnings by $2.2
million.

SEC Staff Accounting Bulletins

SAB No. 109, Written Loan Commitments Recorded at Fair Value Through Earnings.SAB No. 109 supersedes SAB 105, Application of Accounting Principles to Loan Commitments, and indicates
that the expected net future cash flows related to the associated servicing of the loan should be included in the measurement of all written loan commitments that are accounted for at fair value through earnings. The guidance in SAB 109 is
applied on a prospective basis to derivative loan commitments issued or modified in fiscal quarters beginning after December 15, 2007. The adoption of SAB 109 did not significantly impact the Companys financial statements.

2. ACQUISITIONS

Acquisitions are an
integral part of the Companys growth strategy. All acquisitions were accounted for using the purchase method of accounting. Accordingly, the assets and liabilities of the acquired entities were recorded at their fair values at the acquisition
date. The excess of the purchase price over the estimated fair value of the net assets for each acquisition was recorded as goodwill, none of which was deductible for tax purposes. The identified core deposit intangibles for each acquisition are
being amortized using an accelerated amortization method over an 8 to 10 year life. The results of operations for each acquisition have been included in the Companys consolidated financial results beginning on the respective acquisition date.
The following acquisitions were completed on the dates indicated:

On January 10, 2008, the Company completed its acquisition of six
(6) Houston retail branches from Banco Popular North America. In connection with the acquisition, the Company assumed approximately $125.0 million

in deposits and six (6) banking centers. In the second quarter of 2008, one banking center was closed and consolidated with a nearby Prosperity banking
center. The Company paid a premium of $13.0 million or 10.1% to assume the deposits of Banco Popular.

In connection with the purchase, the
Company recorded a premium of $14.4 million, of which $1.3 million was identified as core deposit intangibles. The remaining $13.1 million of the premium was recorded as goodwill.

On June 1, 2008, the Company completed its acquisition of 1st Choice Bancorp, Inc and its wholly-owned subsidiary, 1st Choice Bank. 1st Choice
operated two (2) banking offices in Houston, Texas, with one location in South Houston and another in the Heights area. Prosperitys Heights banking center was consolidated with the 1st Choice Heights location, with the resulting banking
center being located in 1st Choices Heights banking office. As of March 31, 2008, 1st Choice had, on a consolidated basis, total assets of $313.9 million, loans of $198.9 million, deposits of $285.1 million and stockholders equity
of $27.5 million. Under the terms of the definitive agreement, Prosperity issued 1,757,752 shares of Prosperity common stock plus approximately $18,758,000 in cash for all outstanding shares of 1st Choice.

In connection with the purchase, the Company recorded a premium of $51.1 million, of which $637,000 was identified as core deposit intangibles. The
remaining $50.5 million of the premium was recorded as goodwill.

On November 7, 2008, the Bank assumed approximately $3.6 billion of
deposits and acquired certain assets from the FDIC, acting in its capacity as receiver for Franklin Bank (the Franklin acquisition or the Franklin Bank acquisition). The FDIC entered into a purchase and assumption agreement
with the Bank, which paid a premium of $60.9 million to ensure that all deposits of Franklin Bank, both insured and uninsured, were transferred to it. Under terms of the purchase and assumption agreement, the Bank acquired certain assets from the
FDIC, including approximately $350 million in U.S. Treasury and Agency Securities and approximately $360 million in performing loans. The remaining net proceeds were predominately invested in mortgage backed securities primarily issued by federal
government agencies such as Ginnie Mae, Freddie Mac and Fannie Mae. The purchase and assumption transaction was accounted for as a business acquisition in accordance with SFAS 141.

The purchase and assumption agreement also provided the Bank with an option to purchase at fair value any or all of the owned premises of the
banking offices of Franklin Bank and to assume the leases of the leased banking offices by providing written notice to the FDIC within 120 days after November 7, 2008. The Bank intends to purchase twenty-nine (29) of the
owned banking offices for an aggregate of approximately $27.0 million and to assume the leases for six (6) banking offices. In addition, under the terms of the purchase and assumption agreement the Bank is required to purchase the
furniture, fixtures and equipment at any banking office it purchases or leases. Accordingly, the Bank intends to purchase approximately $2.0 million in furniture, fixtures and equipment from the FDIC. The Bank expects
to complete these purchases in the second quarter of 2009.

While Franklin Bank operated forty-five (45) full service banking offices,
the Company expects to continue to operate no more than thirty-five (35) of these locations upon the completion of the operational integration expected to occur during the first quarter of 2009. The former Franklin Bank locations planned to be
closed will be consolidated into nearby Prosperity Bank locations.

In connection with the purchase, the Company recorded a premium of $60.9 million. The allocation of
the purchase price to Franklin Banks assets and liabilities has not been completed as of December 31, 2008. The Company expects to allocate a portion of the premium to Franklin Banks loans, certificates of deposits and core deposit
intangibles. These allocations will be adjusted as information is finalized about the fair value of assets acquired and liabilities assumed.

had an additional banking office under construction in Katy, Texas, which became a full-service banking center of the Company upon completion in July 2006. As of December 31, 2005, SNB had, on a consolidated basis, total assets of $1.025
billion, loans (including loans held for sale) of $652.8 million, deposits of $892.0 million and shareholders equity of $82.5 million.

The table below summarizes select pro forma data for the combined company for the periods indicated assuming the SNB acquisition was effective on January 1 of 2006.

The pro forma results are not necessarily indicative of what actually would have occurred if the
SNB acquisition had occurred on January 1 of each indicated period, or of any future consolidated results.

In connection with the
purchase, the Company recorded a premium of $166.7 million, of which $5.7 million was identified as core deposit intangibles. The remaining $161.0 million of the premium was recorded as goodwill.

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 December 31, 2008, there was no impairment recorded on goodwill.

Core deposit intangibles (CDI) 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 $69.5 million and $67.6 million at December 31, 2008 and December 31, 2007,
respectively. Net core deposit intangibles outstanding were $38.2 million and $46.1 million at the same dates, respectively. Amortization expense related to intangible assets totaled $9.8 million and $9.9 million for the years ended
December 31, 2008 and 2007, respectively. The changes are primarily due to the core deposit intangibles from the 1stChoice and Banco Popular
branch acquisitions and amortization. Although the Bank completed the Franklin acquisition in November 2008, the Company has not yet determined the allocation of the purchase price to CDI with respect to the Franklin Bank deposits assumed and
accordingly no amortization expense was recorded in 2008. The Company expects the completion of the allocation to result in an increase in CDI and a corresponding increase in amortization expense in future periods.

The estimated aggregate future amortization expense for intangible assets remaining as of December 31, 2008 is as follows (dollars in thousands):



|           |  |   |       
|---------- |  | - | ------
|2009       |  | $ | 8,738

4. CASH AND DUE FROM BANKS

The Bank is required by the Federal Reserve Bank of Dallas to maintain average reserve balances. Cash and due from banks in the consolidated balance sheets includes amounts so restricted of $71.3 million
and $25.6 million at December 31, 2008 and 2007, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



In estimating other-than-temporary impairment losses, management considers, among other things,
(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 and (iii) the intent and ability of the Company to retain its investment in the
issuer for a period of time sufficient to allow for any anticipated recovery in fair value.

As part of its regular quarterly review for
impairment of marketable securities, the Company recognized an other-than-temporary impairment charge of $14.0 million pre-tax and $10.0 million pre-tax on Federal Home Loan Mortgage Corporation (FHLMC or Freddie Mac) and on Federal
National Mortgage Association (FNMA or Fannie Mae) government sponsored, investment grade perpetual callable preferred securities as of December 31, 2008 and 2007, respectively. The other-than-temporary-impairment charges were
recorded on six perpetual preferred stock issues classified as available for sale investment securities with a total book value (prior to recognition of the impairment charges) of $24.0 million. The Company decided to reclassify the unrealized
mark-to-market loss on these investment grade securities to an other-than-temporary impairment charge because of the significant decline in the market value of these securities and because management believes it is unlikely that these securities
will recover their original book value within a reasonable amount of time. Both FHLMC and FNMA securities were investment grade at the time of purchase. Market value decreases on available for sale securities are recorded as an unrealized
mark-to-market loss and reflected as a reduction to shareholders equity through other comprehensive income. Accordingly, the reclassification of the unrealized after tax loss to an other-than-temporary impairment non-cash charge did not affect
shareholders equity, or tangible shareholders equity.

Management has the ability and intent to hold its securities until they
mature, at which time the Company will receive full value for the securities. The gross 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 investments approach their maturity date or repricing date or if market yields for such investments decline. Management does not believe any of the securities in an unrealized loss position at December 31,
2008 are impaired due to reasons of credit quality. Accordingly, as of December 31, 2008, management believes the impairments detailed in the table above are temporary and no impairment loss has been realized in the Companys consolidated
statements of income other than discussed above.

8. FAIR VALUE

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. In accordance with the FASB Staff
Position 157-2, Effective Date of SFAS No. 157, the Company has not applied the provisions of this statement to non-financial assets and liabilities such as other real estate owned and repossessed assets.

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 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. 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 SFAS 157.

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 twelve months ended December 31, 2008, the Company had additions to
impaired loans of $12.3 million, which were outstanding December 31, 2008. Remaining financial assets and financial liabilities measured at fair value on a non-recurring basis which were recorded in 2008 and remained outstanding at
December 31, 2008 were not significant.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



Interest expense for certificates of deposit in excess of $100,000 was $37.5 million, $36.4 million
and $24.1 million, for the years ended December 31, 2008, 2007 and 2006, respectively.

The Company has no brokered deposits and there
are no major concentrations of deposits with any one depositor.

11. 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 December 31, 2008, the Company had $229.4 million in FHLB borrowings, of which $29.4 million consisted of long-term
FHLB notes payable and $200.0 million consisted of short-term advances compared with $31.5 million in FHLB borrowings at December 31, 2007, all of which consisted of long-term FHLB notes payable. The weighted average interest rate paid on the
FHLB notes payable at period end was 5.3%. The maturity dates on the FHLB notes payable range from the years 2009 to 2028 and have interest rates ranging from 3.08% to 6.12%. The highest outstanding balance of FHLB advances during 2008 was $280.0
million compared with $240.0 million during 2007. The Company had no federal funds purchased at December 31, 2008 or 2007.

At
December 31, 2008, the Company had $96.0 million in over-night securities sold under repurchase agreements compared with $84.6 million at December 31, 2007, an increase of $11.4 million or 13.5%.

The following table presents the Companys borrowings at December 31, 2008 and December 31, 2007:



|                                            |  |                        |         |              |   |

12. INTEREST RATE RISK

The Company is principally engaged in providing real estate, consumer and commercial loans, with interest rates that are both fixed and variable. These loans are primarily funded through short-term demand deposits and
longer-term certificates of deposit with variable and fixed rates. The fixed real estate loans are more sensitive to interest rate risk because of their fixed rates and longer maturities.

13. FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK

In the normal course of business, the Company is a party to various financial instruments with off-balance-sheet risk to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby
letters of credit, which involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The contract or notional amounts of these instruments reflect the extent of the
Companys involvement in particular classes of financial instruments.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



The Companys exposure to credit loss in the event of nonperformance by the other party to the
financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of these instruments. The Company uses the same credit policies in making these commitments and conditional obligations as
it does for on-balance-sheet instruments.

The following is a summary of the contract or notional amount of the various financial
instruments entered into by the Company:



|                             |  |                        |         |      |   |        
|---------------------------- |  | ---------------------- | ------- | ---- | - | -------
|                             |  | December 31,          
|                             |  | 2008                   |         | 2007
|                             |  | (Dollars in thousands)
|Commitments to extend credit |  | $                      | 685,679 |      | $ | 681,052
|Standby letters of credit    |  |                        | 28,267  |      |   | 16,112 

Commitments to extend credit are agreements to lend to a customer as long as there is no violation
of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being fully drawn upon, the
total commitment amounts disclosed above do not necessarily represent future cash funding requirements. At December 31, 2008, $107.2 million of commitments to extend credit have fixed rates ranging from 3.10% to 18.00%.

Standby letters of credit are written conditional commitments issued by the Company to guarantee the performance of a customer to a third party. In the
event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is
represented by the contractual amount of the commitment. If the commitment is funded, the Company would be entitled to seek recovery from the customer. The Companys policies generally require that standby letter of credit arrangements contain
security and debt covenants similar to those contained in loan agreements.

The Company evaluates customer creditworthiness on a
case-by-case basis. The amount of collateral obtained, if considered necessary by the Company upon extension of credit, is based on managements credit evaluation of the customer.

14. INCOME TAXES

The components of the provision for federal income taxes are as follows:



|          |  |                         |        |      |   |        |  |   |

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable
income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based
upon the level of historical taxable income and estimates of future taxable income over the periods for which the deferred tax assets are deductible, management believes it is more likely than not the Company will realize the benefits of these
deductible differences at December 31, 2008. The change in the Companys deferred tax assets and liabilities include purchase accounting adjustments.

The Company adopted FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement 109 on January 1, 2007. FASB Interpretation No. 48
prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Benefits from tax positions should be recognized in the financial
statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the
more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not
recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be
derecognized in the first subsequent financial reporting period in which that threshold is no longer met. FASB Interpretation No. 48 also provides guidance on the accounting for and disclosure of unrecognized tax benefits, interest and penalties.
The Companys policy for recording interest and penalties associated with audits is to record such items as a component of income before taxes. Penalties are recorded in other (gains) losses and interest paid or received is recorded in interest
expense or interest income, respectively, in the consolidated statement of income. The Company has identified its federal tax return and its state tax return in Texas as major tax jurisdictions, as defined. The only periods subject to
examination for the Companys federal return are the 2005 through 2007 tax years.

15. STOCK INCENTIVE PROGRAMS

At December 31, 2008, 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. Prior to 2003, the Company accounted for those plans under the recognition and measurement provisions of APB Opinion No. 25, Accounting for Stock Issued to Employees, and
related Interpretations. Effective January 1, 2003, the Company prospectively adopted the fair value recognition provisions of SFAS No. 123, Accounting for Stack-Based Compensation, as provided by SFAS No. 148 for stock-based
employee compensation. The Company adopted SFAS 123(R) on January 1, 2006. The Company recognized $1.5 million and $2.0 million in stock-based compensation expense for the years ended December 31, 2008 and 2007, respectively. There
was approximately $334,000 and $409,000 of income tax benefit recorded for the stock-based compensation expense for the same periods.

During 1995, the Companys Board of Directors approved a stock option plan (the 1995 Plan) for executive officers and key associates to purchase common stock of Bancshares. A total of 675,000 options have been granted under
the 1995 Plan as of December 31, 2008. The maximum number of shares reserved for issuance pursuant to options granted under the 1995 Plan was 680,000 (after two-for-one and four-for-one stock splits). Options to acquire a total of 15,000 shares
of Common Stock of Bancshares were outstanding at December 31, 2008, of which none were exercisable. The 1995 Plan expired on July 31, 2005 and therefore no additional options may be issued from the 1995 Plan.

On January 31, 2007, the Company acquired Texas United Bancshares, Inc. The options to purchase
shares of Texas United Bancshares, Inc. common stock outstanding at the effective time of the transaction were converted into options to purchase a total of 179,956 shares of Bancshares Common Stock at exercise prices ranging from $5.00 to $20.16
per share. The converted options are governed by the original plan under which they were issued. Options to purchase a total of 19,300 shares of Common Stock of Bancshares were outstanding at December 31, 2008.

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:

17. PROFIT SHARING PLAN

The Company has adopted a profit sharing plan pursuant to Section 401(k) of the Internal Revenue Code whereby the participants may contribute a percentage of their compensation as
permitted under the Code. Matching contributions are made at the discretion of the Company. Presently, the Company matches 50% of an employees contributions, up to 15% of such employees compensation,
not to exceed the maximum allowable pursuant to the Internal Revenue Code and excluding catch-up contributions. Such matching contributions were approximately $1.7 million, $1.6 million and $1.0 million for the years ended
December 31, 2008, 2007 and 2006, respectively.

18. COMMITMENTS AND CONTINGENCIES

LeasesThe following table presents a summary of non-cancelable future operating lease commitments as of December 31, 2008 (dollars in
thousands):



|           |  |   |       
|---------- |  | - | ------
|2009       |  | $ | 3,732 
|2010       |  |   | 3,011 
|2011       |  |   | 2,172

|Thereafter |  |   | 2,198 
|           |  |   |       
|Total(1)   |  | $ | 13,732
|           |  |   |       



|(1) | With respect to Franklin Bank, the table above only presents future operating lease commitments on the six (6) leased locations the Bank intends to assume.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------

It is expected that in the normal course of business, expiring leases will be renewed or replaced by leases on other property or equipment.

Rent expense under all noncancelable operating lease obligations aggregated approximately $4.7 million for the year ended
December 31, 2008, $3.9 million for the year ended December 31, 2007 and $3.4 million for the year ended December 31, 2006.

LitigationThe Company has been named as a defendant in various legal actions arising in the normal course of business. In the opinion of management, after reviewing such claims with outside counsel, resolution of such matters will not
have a materially adverse impact on the consolidated financial statements.

19. REGULATORY MATTERS

The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Any institution that fails
to meet its minimum capital requirements is subject to actions by regulators that could have a direct material effect on the Companys and the Banks financial statements. Under the capital adequacy guidelines and the regulatory framework
for prompt corrective action, the Bank must meet specific capital guidelines based on the Banks assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The Companys and the Banks
capital amounts and the Banks classification under the regulatory framework for prompt corrective action are also subject to qualitative judgements by the regulators about the components, risk weightings and other factors.

To meet the capital adequacy requirements, the Company and the Bank must maintain minimum capital amounts and ratios as defined in the regulations. As of
December 31, 2008, the Company and the Bank met all capital adequacy requirements to which they are subject.

At December 31,
2008, the most recent notification from the FDIC categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized the Bank must maintain minimum total risk-based,
Tier I risk-based and Tier I leverage ratios as set forth in the table. There have been no conditions or events since that notification which management believes have changed the Banks category.

20. DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

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.

Interest-Bearing Deposits in Financial Institutions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.

Federal Home Loan Bank Notes
Payable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.

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.

21. JUNIOR SUBORDINATED DEBENTURES

At December 31, 2008 and 2007, the Company had outstanding $92.3 million and $112.9 million, respectively, in junior subordinated debentures issued to the Companys unconsolidated subsidiary trusts. The decrease of $20.6 million
was due to the Companys redemption of $10.3 million in junior subordinated debentures issued to each of SNB Statutory Trust II and SNB Capital Trust III on June 26, 2008 and April 7, 2008, respectively. Each issue of debentures
redeemed bore interest at a floating rate of 3- month LIBOR + 3.15%. The trusts in turn redeemed in full the trust preferred securities and common securities they issued.

Each of the trusts is a capital or statutory business trust organized for the sole purpose of issuing trust securities and
investing the proceeds in the Companys junior subordinated debentures. The preferred trust securities of each trust represent preferred beneficial interests in the assets of the respective trusts and are subject to mandatory redemption upon
payment of the junior subordinated debentures held by the trust. The common securities of each trust are wholly-owned by the Company. Each trusts ability to pay amounts due on the trust preferred securities is solely dependent upon the Company
making payment on the related junior subordinated debentures. The debentures, which are the only assets of each trust, are subordinate and junior in right of payment to all of the Companys present and future senior indebtedness. The Company
has fully and unconditionally guaranteed each trusts obligations under the trust securities issued by such trust to the extent not paid or made by each trust, provided such trust has funds available for such obligations.

Under the provisions of each issue of the debentures, the Company has the right to defer payment of interest on the debentures at any time, or from time
to time, for periods not exceeding five years. If interest payments on either issue of the debentures are deferred, the distributions on the applicable trust preferred securities and common securities will also be deferred.
