UNLESS OTHERWISE INDICATED, ALL SHARE AND PER SHARE INFORMATION HAS BEEN ADJUSTED TO GIVE EFFECT TO A FOUR FOR ONE COMMON STOCK SPLIT EFFECTED IN THE FORM OF A STOCK DIVIDEND EFFECTIVE AS OF SEPTEMBER 10, 1998.

REFERENCES TO THE COMPANY IN THIS PROSPECTUS INCLUDE REFERENCES TO FIRST PROSPERITY BANK WHERE THE CONTEXT REQUIRES.

THE COMPANY

Prosperity Bancshares, Inc. (the "Company") is a bank holding company headquartered in Houston, Texas. The Company derives substantially all of its income from the operation of its wholly-owned bank subsidiary, First Prosperity Bank (the "Bank"), which has 11 full-service banking locations ("Banking Centers") in the greater Houston metropolitan area and six contiguous counties situated south and southwest of Houston. As of June 30, 1998, the Company had total assets of $335.4 million, gross loans of $141.1 million, total deposits of $307.8 million and total shareholders' equity of $26.5 million. The Company's financial performance has been characterized by steady asset growth, consistent core earnings and strong asset quality. The Company has been profitable in every year of its existence.

The Company was formed in 1983 as a vehicle to acquire the former Allied Bank in Edna, and has grown through a combination of internal growth, the acquisition of community banks and the opening of new community banking offices. From 1988 to 1992, as a sound and profitable institution, the Company took advantage of the economic downturn in Texas and acquired the deposits and certain assets of failed banks in West Columbia, El Campo and Cuero and two failed banks in Houston. The Company opened a full-service Banking Center in Victoria in 1993 and the following year established a Banking Center in Bay City. The Company expanded its Bay City presence in 1996 with the acquisition of an additional branch location from Norwest Bank and in 1997 the Company acquired the Angleton 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. As a result of the addition of these branches and internal growth, the Company's assets have increased from $54.2 million at the end of 1987 to $335.4 million as of June 30, 1998 and its deposits have increased from $46.0 million to $307.8 million in that same period. In addition, the Company has executed a definitive agreement to acquire Union State Bank ("Union") in East Bernard, which had $76.9 million in assets and $63.7 million in deposits as of June 30, 1998. The acquisition of Union is expected to close on or before October 1, 1998 and to be immediately accretive to the Company's earnings.

The Company's primary market consists of the communities served by its three locations in the greater Houston metropolitan area and its eight locations in six contiguous counties (Brazoria, Wharton, Matagorda, Jackson, Victoria and DeWitt) neighboring Houston. 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. The Company's market areas outside of Houston 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 branch 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's Board members and executive officers play an important role in the Company's business development efforts by actively participating in a number of civic and public service

3

activities in the local communities served by the Company. The Company has invested heavily in its officers and employees by recruiting talented bankers in its market areas and rewarding excellent performance with stock options and other economic incentives. Each of the Company's Banking Centers is administered by a local President and operated as a separate profit center, with each Banking Center President being held accountable for his Banking Center's performance and compensated accordingly.

The Company offers a variety of traditional loan and deposit products to its customers, which consist primarily of consumers and small and medium-sized businesses. The Company tailors its products to the specific needs of customers in a given market. The Company offers consumers home mortgage loans with adjustable rates, automobile loans, home equity loans, debit cards and cash management services. For businesses, the Company makes available 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. The Company provides all of its customers with a full complement of traditional deposit products.

The Company's strategic plan includes the following goals:

o INCREASE LOAN VOLUME AND DIVERSIFY LOAN PORTFOLIO. The Company seeks to increase its ratio of loans to deposits from the June 30, 1998 level of 42.1% to approximately 65%. Given the Company's high level of low-cost core deposits, increased lending activity is expected to significantly enhance the Company's net income. Historically, the Company has elected to sacrifice some earnings for the relative security of home mortgage loans. While maintaining its conservative approach to lending, the Company plans to emphasize loan products such as home equity loans and loans to finance the construction of commercial owner-occupied real estate, and target professional service firms such as legal and medical practices and their principals in an effort to improve the mix of its loan portfolio.

o MAINTAIN EFFICIENCY RATIO. The Company has always emphasized cost control. The Company has invested significantly in the infrastructure required to centralize many of its critical operations, which management believes can accommodate substantial additional growth and minimize operational costs through certain economies of scale. Since 1993, the Company has acquired two branch locations and established two new offices while improving its efficiency ratio in each consecutive year.

o ENHANCE CROSS-SELLING. The Company trains and incents its employees to cross-sell various products. To assist in this effort, the Company has updated its technology to help its officers and employees identify cross-selling opportunities through a readily accessible Customer Information File. Recent cross-selling efforts have targeted the Company's existing mortgage and home equity loan customers and small and medium-sized businesses for the sale of additional loan and deposit products.

o AUGMENT MARKET SHARE. In recent years, the Company has increased its market share in each of the communities in which it maintains a Banking Center. The Company intends to continue seeking opportunities to expand either by acquiring existing banks or branches of banks or by establishing new branches. All of the Company's acquisitions have been accretive to earnings immediately and have supplied the Company with relatively low-cost deposits which have been used to fund the Company's lending activities.

RISK FACTORS

AN INVESTMENT IN THE COMMON STOCK OFFERED HEREBY INVOLVES CERTAIN RISKS. IN ADDITION TO THE OTHER INFORMATION CONTAINED OR INCORPORATED BY REFERENCE HEREIN, THE FOLLOWING FACTORS SHOULD BE CONSIDERED CAREFULLY IN EVALUATING THE COMPANY BEFORE PURCHASING THE COMMON STOCK OFFERED HEREBY. INFORMATION CONTAINED IN THIS PROSPECTUS CONTAINS "FORWARD-LOOKING STATEMENTS" WHICH CAN BE IDENTIFIED BY THE USE OF FORWARD-LOOKING TERMINOLOGY SUCH AS "BELIEVES," "EXPECTS," "WILL," "SHOULD," "PROJECTED," "CONTEMPLATED" OR "ANTICIPATES" OR THE NEGATIVE THEREOF OR OTHER VARIATIONS THEREON OR COMPARABLE TERMINOLOGY. NO ASSURANCE CAN BE GIVEN THAT THE FUTURE RESULTS COVERED BY THE FORWARD-LOOKING STATEMENTS WILL BE ACHIEVED. THE FOLLOWING FACTORS COULD CAUSE ACTUAL EXPERIENCE TO VARY MATERIALLY FROM THE FUTURE RESULTS COVERED IN SUCH FORWARD-LOOKING STATEMENTS. OTHER FACTORS, SUCH AS THE GENERAL STATE OF THE ECONOMY, COULD ALSO CAUSE ACTUAL EXPERIENCE TO VARY MATERIALLY FROM THE MATTERS COVERED IN SUCH FORWARD-LOOKING STATEMENTS.

RISKS INVOLVED IN ACQUISITIONS

The Company believes that a portion of its growth will come from acquisitions of banks and other financial institutions. Such acquisitions, including the acquisition of Union (the "Union Acquisition"), currently expected to be consummated prior to the consummation of the Offering, involve risks of changes in results of operations or cash flows, unforeseen liabilities relating to the acquired institution or arising out of the acquisition, asset quality problems of the acquired entity and other conditions not within the control of the Company, such as adverse personnel relations, loss of customers because of change of identity, deterioration in local economic conditions and other risks affecting the acquired institution. See "Pending Acquisition." There can be no assurance that any such acquisitions will enhance the Company's business, results of operations, cash flows or financial condition, and such acquisitions may have an adverse effect on the Company's results of operations, particularly during periods in which the acquisitions are being integrated into the Company's operations. Operational areas requiring significant integration include the consolidation of data processing operations, the combination of employee benefit plans, the creation of joint account and lending products, the development of unified marketing plans and other related areas. Successful integration of acquired entities could require significant expenditures by the Company that could negatively impact the Company's results of operations. Completion of the acquisition and integration could divert management's attention from other important issues and impact the Company's operating results. There can be no assurance that the Company will be able to identify other suitable acquisition candidates, that acquisitions will be consummated on acceptable terms or that the Company will be able to successfully integrate the operations of any acquired entity or business. The Company's ability to acquire banks and other financial institutions may depend on its ability to obtain additional debt and equity funding which may not be available on terms as favorable to the Company as currently available and, if equity funding is utilized, an acquisition may be dilutive to shareholders.

EXPOSURE TO LOCAL ECONOMIC CONDITIONS

The Company's success is dependent to a significant extent upon general economic conditions in Texas and to a certain extent, the metropolitan Houston area. The banking industry in Texas and Houston is affected by general economic conditions such as inflation, recession, unemployment and other factors beyond the Company's control. During the mid 1980s, severely depressed oil and gas and real estate prices materially and adversely affected the Texas and Houston economies, causing recession and unemployment in the region and resulting in excess vacancies in the Houston real estate market and elsewhere in the state. Since 1987, the Texas economy has improved in part due to its expansion into industries other than those related to energy. As the Texas and Houston economies have diversified away from the energy industry, however, they have become more susceptible to adverse effects resulting from recession in the national economy. Economic recession over a prolonged period or other economic dislocation in the Texas and Houston area could cause increases in nonperforming assets, thereby causing operating losses, impairing liquidity and eroding capital. There can be no assurance that future adverse changes in the Texas or Houston

8

economies would not have a material adverse effect on the Company's financial condition, results of operations or cash flows.

INTEREST RATE RISK

The Company's earnings depend to a great extent on "rate differentials," which are the differences between interest income that the Company earns on loans and investments and the interest expense paid on deposits and other borrowings. These rates are highly sensitive to many factors which are beyond the Company's control, including general economic conditions and the policies of various government and regulatory authorities. Increases in the discount rate by the Board of Governors of the Federal Reserve System ("Federal Reserve Board") usually lead to rising interest rates, which affect the Company's interest income, interest expense and investment portfolio. Also, certain governmental policies affect the cost of funds. From time to time, maturities of assets and liabilities are not balanced, and a rapid increase or decrease in interest rates could have an adverse effect on the net interest margin and results of operations of the Company. The nature, timing and effect of any future changes in federal monetary and fiscal policies on the Company and its results of operations are not predictable. See "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Financial Condition -- Interest Rate Sensitivity and Liquidity."

COMPETITION

The banking business is highly competitive, and the profitability of the Company depends principally upon the Company's ability to compete in the market areas in which its banking operations are located. 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 non-bank 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. Many of such competitors may have greater financial and other resources than the Company. The Company has been able to compete effectively with other financial institutions by emphasizing customer service, technology and responsive decision-making on 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. Although the Company has been able to compete effectively in the past, no assurances may be given that the Company will continue to be able to compete effectively in the future. Various legislative acts in recent years have led to increased competition among financial institutions. There can be no assurance that the United States Congress or the Texas legislature will not enact legislation that may further increase competitive pressures on the Company. Competition from both financial and non-financial institutions is expected to continue. See "The Company -- Competition."

REGULATION AND SUPERVISION

Bank holding companies and banks operate in a highly regulated environment and are subject to extensive supervision and examination by several federal and state regulatory agencies. The Company is subject to the Bank Holding Company Act of 1956, as amended (the "BHCA"), and to regulation and supervision by the Federal Reserve Board. The Bank, as a Texas state banking association, is subject to regulation and supervision by the Texas Banking Department and, as a result of the insurance of its deposits, by the Federal Deposit Insurance Corporation ("FDIC"). These regulations are intended primarily for the protection of depositors and customers, rather than for the benefit of investors. The Company and the Bank are subject to changes in federal and state laws, as well as changes in regulations and governmental policies, income tax laws and accounting principles. The effects of any potential changes cannot be predicted but could adversely affect the business, operations and cash flows of the Company and the Bank in the future. See "Supervision and Regulation."

The Federal Reserve Board has adopted a policy that requires a bank holding company such as the Company to serve as a source of financial strength to its banking subsidiaries. The Federal Reserve Board has required bank holding companies to contribute cash to their troubled bank subsidiaries based upon this

9

"source of strength" policy, which could have the effect of decreasing funds available for distributions to shareholders. In addition, a bank holding company in certain circumstances could be required to guarantee the capital plan of an undercapitalized banking subsidiary. See "Supervision and Regulation."

DIVIDEND HISTORY AND RESTRICTIONS ON ABILITY TO PAY DIVIDENDS

While the Company currently pays cash dividends on the Common Stock, there is no assurance that the Company will pay dividends on the Common Stock in the future. 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.

The Company's principal source of funds to pay dividends on the shares of Common Stock will be cash dividends that the Company receives from the Bank. The payment of dividends by the Bank to the Company is subject to certain restrictions imposed by federal and state banking laws, regulations and authorities. The federal banking statutes prohibit federally insured banks from making any capital distributions (including a dividend payment) if, after making the distribution, the institution would be "undercapitalized" as defined by statute. In addition, the relevant federal regulatory agencies also have authority to prohibit an insured bank from engaging in an unsafe or unsound practice, as determined by the agency, in conducting an activity. The payment of dividends could be deemed to constitute such an unsafe or unsound practice, depending on the financial condition of the Bank. 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. As of June 30, 1998, an aggregate of approximately $6.2 million was available for payment of dividends by the Bank to the Company under applicable restrictions, without regulatory approval. See "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Financial Condition -- Capital Resources" and "Supervision and Regulation -- The Bank."

DEPENDENCE ON KEY PERSONNEL

The Company and the Bank are dependent on certain key personnel including Tracy T. Rudolph and David Zalman, both of whom are considered to be important to the success of the Company and the Bank. The unexpected loss of Messrs. Rudolph or Zalman or other members of senior management could have an adverse effect on the Company and the Bank. The Company has entered into an employment agreement with each of Messrs. Rudolph and Zalman. See "Management -- Employment Agreements."

CERTAIN CHARTER AND BYLAW PROVISIONS

The Company's Articles of Incorporation and Bylaws contain certain provisions which may delay, discourage or prevent an attempted acquisition or change of control of the Company. These provisions include: (i) a Board of Directors classified into three classes of directors with the directors of each class having staggered, three-year terms, (ii) a provision that any special meeting of shareholders of the Company may be called only by a majority of the Board of Directors, the Chairman of the Board, the President or the holders of at least 50% of the shares entitled to vote on the matter, (iii) 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 (iv) a provision that denies shareholders the right to amend the Bylaws of the Company. The Company's Articles of Incorporation provide for noncumulative voting for directors and authorize the Board of Directors of the Company to issue shares of preferred stock of the Company, $1.00 par value per share, without shareholder approval and upon such terms as the Board of Directors may determine. The issuance of preferred stock, while providing desirable flexibility in connection with possible acquisitions, financings and other corporate purposes, 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

10

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. See "Supervision and Regulation," "Description of Securities of the Company -- Preferred Stock," and "-- Texas Law and Certain Provisions of the Articles of Incorporation and Bylaws."

MANAGEMENT'S OWNERSHIP INTEREST AND POSSIBLE EFFECTS

After the consummation of the Offering, the executive officers and directors of the Company and members of the Executive Committee of the Bank will beneficially own 21.38% of the outstanding shares of Common Stock, and approximately 20.34% of such shares of Common Stock if the Underwriters' over- allotment option is fully exercised. Accordingly, these executive officers and directors will be able to influence, to a significant extent, the outcome of all matters required to be submitted to the Company's shareholders for approval, including decisions relating to the election of directors of the Company, the determination of day-to-day corporate and management policies of the Company and other significant corporate transactions. See "Management," "Principal and Selling Shareholders" and "Description of Securities of the Company."

DILUTION OF COMMON STOCK

Investors purchasing shares of Common Stock in the Offering will incur immediate dilution of approximately % in their investment, in that the tangible book value of the Company after the Offering will be approximately $ compared with an assumed initial public offering price of $ per share (which is the mid-point of the Offering range). See "Dilution."

NO PRIOR TRADING MARKET

Prior to the Offering, there has been no public market for the shares of Common Stock. An application has been filed to have the Common Stock approved for quotation on the Nasdaq/National Market under the symbol "PRSP." The Representatives have advised the Company that they intend to make a market in the Common Stock as long as the volume of trading activity in the Common Stock and certain other market making conditions justify doing so. Nonetheless, there can be no assurance that an active public market will develop or be sustained after the Offering or that if such a market develops, investors in the Common Stock will be able to resell their shares at or above the initial public offering price. Making a market involves maintaining bid and asked quotations for the Common Stock and being available as principal to effect transactions in reasonable quantities at those quoted prices, subject to various securities laws and other regulatory requirements. A public trading market having the desired characteristics of depth, liquidity and orderliness depends upon the presence in the marketplace of willing buyers and sellers of the Common Stock at any given time, which presence is dependent upon the individual decisions of investors over which neither the Company nor any market maker has any control.

DETERMINATION OF MARKET PRICE AND POSSIBLE VOLATILITY OF STOCK PRICE

The initial public offering price of the shares of Common Stock will be determined by negotiations between the Company and the Representatives and will not necessarily bear any relationship to the Company's book value, past operating results, financial condition or other established criteria of value and may not be indicative of the market price of the Common Stock after the Offering. See "Nature of the Trading Market and Market Prices" and "Underwriting" for information relating to the method of determining the initial public offering price. The stock market has from time to time experienced price and volume volatility. These market fluctuations may be unrelated to the operating performance of particular companies whose shares are traded and may adversely affect the market price of the Common Stock. There can be no assurance that the market price of the Common Stock will not decline below the initial public offering price.

SHARES ELIGIBLE FOR FUTURE SALE

The Company will have 4,915,308 shares of Common Stock outstanding after the Offering. The Company, its officers and directors and certain shareholders (who collectively will own 32.71% of the

11

outstanding shares after the consummation of the Offering) have agreed with the Representatives not to offer, sell, contract to sell or otherwise dispose of any of their shares of Common Stock for a period of 180 days after the date of this Prospectus without the permission of the Representatives. The currently outstanding shares of Common Stock which are not subject to such agreement are held by approximately 140 shareholders of record, and all of such shares are "restricted securities" as that term is defined by Rule 144 promulgated under the Securities Act of 1933, as amended (the "Securities Act") and will be eligible for sale in compliance with Rule 144 volume and other requirements. Shares held for at least two years by a person who has not been an "affiliate" of the Company at any time during the 90 days preceding the sale of such shares will be freely tradable in accordance with Rule 144(k) under the Securities Act, without regard to volume and other restrictions of Rule 144. In addition, all of the shares of Common Stock sold in the Offering, other than shares purchased by affiliates of the Company, will generally be freely tradable under the Securities Act. No prediction can be made as to the effect, if any, that future sales of Common Stock or the availability of Common Stock for future sale will have on the market price of the Common Stock prevailing from time to time. Sales of a substantial number of such shares in the future, or the perception that such sales could occur, could adversely affect the market price of the Common Stock. See "Management" and "Principal and Selling Shareholders."

REGULATION OF CONTROL

Individuals, alone or acting in concert with others, seeking to acquire 10% or more of any class of voting securities of the Company must comply with the Change in Bank Control Act, which requires the prior approval of the Federal Reserve Board for any such acquisition. Entities seeking to acquire 5% or more of any class of voting securities of, or otherwise to control, the Company may be required to obtain the prior approval of the Federal Reserve Board under the BHCA. Accordingly, prospective investors need to be aware of and to comply with these requirements, if applicable, in connection with any purchase of shares of the Common Stock offered hereby.

YEAR 2000 ISSUES

Significant uncertainty exists concerning the potential effects associated with "Year 2000" issues. The Company formally initiated a project in November 1997 to ensure that its operational and financial systems will not be adversely affected by Year 2000 software problems. The Company has formed a Year 2000 project team and the Board of Directors and management are supporting all compliance efforts and allocating the resources that management believes are necessary to ensure completion. An inventory of all systems and products that could be affected by the Year 2000 date change has been developed, verified and categorized as to its importance to the Company. The software for the Company's systems is primarily provided through service bureaus and software vendors. The Company is requiring its software providers to demonstrate and represent that the products provided are or will be Year 2000 compliant and has planned a program of testing compliance. In the event that its data processing system does not function properly, the Company is prepared to perform functions manually. The Company believes it is in compliance with regulatory guidelines regarding Year 2000 compliance, including the timetable for achieving compliance. Management does not expect the costs of bringing the Company's systems into Year 2000 compliance will have a material adverse effect on the Company's financial condition, results of operations or liquidity. Nonetheless, the Company's ability to predict the costs associated with Year 2000 compliance is subject to some uncertainties, and the Company may incur unexpected additional expenditures in connection with Year 2000 compliance, which expenditures could be material. In addition, there can be no assurance that the Company's operational and financial systems will not be affected by Year 2000 software problems.

THE COMPANY

GENERAL

The Company was formed in 1983 as a vehicle to acquire the former Allied Bank in Edna, which was chartered in 1949. The Company's headquarters are located at 3040 Post Oak Boulevard in Houston, Texas and its telephone number is
(713) 993-0002. As of June 30, 1998, the Company had approximately 155 shareholders of record.

The Company has grown through a combination of internal growth, the acquisition of community banks and the opening of new community banking offices. Utilizing a low cost of funds and employing stringent cost controls, the Company has been profitable in every 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 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 in 1993 and the following year established a Banking Center in Bay City. The Company expanded its Bay City presence in 1996 with the acquisition of an additional branch location from Norwest Bank and in 1997 the Company acquired the Angleton 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. As a result of the addition of these branches and internal growth, the Company's assets have increased from $54.2 million at the end of 1987 to $335.4 million as of June 30, 1998 and its deposits have increased from $46.0 million to $307.8 million in that same period. In addition, the Company has executed a definitive agreement to acquire Union State Bank ("Union") in East Bernard, which had $76.9 million in assets and $63.7 million in deposits as of June 30, 1998. The Union Acquisition will augment the Company's market share in Wharton County and is expected to be immediately accretive to the Company's earnings. See "Pending Acquisition."

The Company's primary market consists of the communities served by its three locations in the greater Houston metropolitan area and its eight locations in six contiguous counties (Brazoria, Wharton, Matagorda, Jackson, Victoria and DeWitt) located to the south and southwest of Houston. Texas Highway 59 (scheduled to become Interstate Highway 69), which serves as one of the primary trucking routes linking the interior United States and Mexico, runs directly through the center of the Company's market area. The increased traffic along this "NAFTA Highway" has enhanced economic activity in the Company's market area and created opportunities for growth. 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 farming, ranching, petrochemicals, manufacturing, tourism, recreation and professional service firms and their principals. The Company's market areas outside of Houston 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 area and excellent growth opportunities through acquisitions, new branch 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'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 a number of civic and public service activities in the communities served by the Company, such as the Rotary Club, Lion's Club, United Way and Chamber of Commerce. In addition, the Company's Banking Centers in Bay City, Clear Lake, Cuero, Edna and Victoria maintain Community Development Boards, whose function is to solicit new business, develop customer relations and provide valuable community knowledge to their respective Banking Center Presidents.

The Company has invested heavily in its officers and employees by recruiting talented officers in its market areas and providing them with economic incentive in the form of stock options and bonuses based

13

on cross-selling performance. The senior management team has substantial experience in both the Houston markets and the surrounding communities in which the Company has a presence. Each Banking Center location is administered by a local President with knowledge of the community and banking skills which complement the local economy. The Company entrusts its Banking Center Presidents with authority and flexibility with respect to product pricing and decision making within general parameters established by the Company. 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 are accountable for performance in these areas and compensated accordingly. Each Banking Center has its own local telephone number, which enables a customer to be served by a local banker.

BUSINESS

The Company offers a variety of traditional loan and deposit products to its customers, which consist primarily of consumers and small and medium-sized businesses. The Company tailors its products to the specific needs of customers in a given market. The Company maintains approximately 25,000 separate deposit accounts and over 5,000 separate loan accounts. At June 30, 1998, approximately 22.3% of the Company's total deposits were noninterest-bearing demand deposits and for the period ended June 30, 1998, the Company's average cost of funds was 3.11%.

The Company has been an active mortgage lender, with one-to-four family and commercial mortgage loans comprising 60.6% of the Company's total loans as of June 30, 1998. The Company also offers loans for automobiles and other consumer durables, home equity loans, debit cards, personal computer banking and other cash management services and telebanking. By offering certificates of deposit, NOW accounts, savings accounts and overdraft protection at competitive rates, the Company gives its depositors a full range of traditional deposit products. The Company has successfully introduced Banclub, which for a monthly fee provides consumers with a package of benefits including unlimited free checking, personalized checks, credit card protection, free travelers checks, cashier's checks and money orders and certain travel discounts.

The businesses targeted by the Company are primarily those that require loans in the $100,000 to $3.0 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. For its business customers, the Company has developed a specialized checking product called Business 10 Checking which provides discounted fees for checking and normal account analysis.

STRATEGY

The Company's strategic plan includes the following goals:

INCREASE LOAN VOLUME AND DIVERSIFY LOAN PORTFOLIO. The Company seeks to increase its ratio of loans to deposits from the June 30, 1998 level of 42.1% to approximately 65%. Given the Company's high level of low-cost core deposits, increased lending activity is expected to significantly enhance the Company's net income. Historically, the Company has elected to sacrifice some earnings for the relative security of home mortgage loans. While maintaining its conservative approach to lending, the Company plans to emphasize both new and existing loan products. Among new loan products, the Company has successfully introduced home equity lending, which contributed $4.7 million in new loans during the first half of 1998. The Company has also increased its number of loans to finance the construction of commercial owner-occupied real estate and loans to commercial businesses for accounts receivable financing and other purposes. With the Union Acquisition, the Company's agricultural loans will increase from $8.4 million to $22.2 million on a pro forma basis as of June 30, 1998. The Company is also targeting professional service firms such as legal and medical practices for both loans secured by owner-occupied premises and personal loans to their principals. As an outgrowth of its traditional mortgage lending activity, the Company is making more jumbo mortgage loans, particularly in the Houston area.

MAINTAIN EFFICIENCY RATIO. The Company has always emphasized cost control. The Company has invested significantly in the infrastructure required to centralize many of its critical operations, such as data processing and loan application 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. The Company maintains a "products committee" which provides support in the areas of product development, marketing and pricing. Management believes that this centralized infrastructure can accommodate substantial additional growth while enabling the Company to minimize operational costs through certain economies of scale. Since 1993, the Company has acquired two branch locations and established two new offices while improving its efficiency ratio in each consecutive year.

ENHANCE CROSS-SELLING. The Company has increased its focus on cross-selling opportunities by training employees to identify and maximize cross-selling opportunities. The Company uses bonuses to encourage cross-selling efforts, and fosters friendly competition among the Banking Centers to achieve better cross-selling results. To assist with cross-selling efforts, the Company has updated its technology to help officers and employees identify cross-selling opportunities through a readily accessible Customer Information File which details personal information, existing account relationships and related account relationships. Recent cross-selling efforts by the Company have targeted the Company's existing mortgage and home equity loan customers and small and medium-sized businesses for the sale of additional loan and deposit products.

AUGMENT MARKET SHARE. In recent years, the Company has increased its market share in each of the communities in which it maintains a Banking Center. 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 branches. All of the Company's acquisitions have been accretive to earnings immediately and have supplied the Company with relatively low-cost deposits which have been used to fund the Company's lending activities. 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 image and market presence.

FACILITIES

The Company conducts business at 11 full-service Banking Centers. The following table sets forth specific information on each such location. The Company's headquarters are located at 3040 Post Oak Boulevard, in Houston, Texas. The Company owns all of the buildings in which its Banking Centers are located other than the Post Oak, Meyerland and Victoria Banking Centers.

COMPETITION

The banking business is highly competitive, and the profitability of the Company depends principally on the Company's ability to compete in its markets. 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 non-bank 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 has been able to compete effectively with other financial institutions by emphasizing customer service, technology and responsive decision-making on 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. See "Risk Factors -- Competition."

EMPLOYEES

As of June 30, 1998, the Company had 118 full-time equivalent employees, 50 of whom were officers of the Bank. The Company provides medical and hospitalization insurance to its full-time employees. The Company considers its relations with employees to be excellent. Neither the Company nor the Bank is a party to any collective bargaining agreement.

LEGAL PROCEEDINGS

The Company and the Bank from time to time are parties to or otherwise involved in legal proceedings arising in the normal course of business. Management does not believe that there is any pending or threatened proceeding against the Company or the Bank which, if determined adversely, would have a material effect on the business, results of operations or financial condition of the Company or the Bank.

USE OF PROCEEDS

The net proceeds to be received by the Company from the Offering (based upon an assumed initial public offering price of $ per share), after deducting the underwriting discount and estimated Offering expenses, are estimated to be approximately $ million, or $ million if the Underwriters' over- allotment option is fully exercised. The Company intends to use all of such proceeds for general corporate purposes, including support for anticipated balance sheet growth, future acquisitions and the repayment of $2.0 million of indebtedness (the "Indebtedness") to another commercial bank incurred in connection with the Union Acquisition. The principal amount of the Indebtedness is repayable over a seven year period and bears interest at the federal funds rate plus 2.75%. The Indebtedness is secured by all of the capital stock of the Bank.

Pending the application of the net proceeds, the Company intends to invest such proceeds in short-term, interest-bearing securities, certificates of deposit or guaranteed obligations of the United States of America.

DIVIDEND POLICY

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 paid dividends on its Common Stock since 1994, there is no assurance that dividends will be paid in the future.

For a foreseeable period of time, the principal source of cash revenues to the Company will be dividends paid by the Bank with respect to the Bank's capital stock. There are certain restrictions on the payment of such dividends imposed by federal and state banking laws, regulations and authorities. See "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Financial Condition -- Capital Resources" and "Supervision and Regulation -- The Bank."

In the future, the declaration and payment of dividends on the Common Stock will depend upon the earnings and financial condition of the Company, liquidity and capital requirements, the general economic and regulatory climate, the Company's ability to service any equity or debt obligations senior to the

16

Common Stock and other factors deemed relevant by the Company's Board of Directors. See "Supervision and Regulation" and "Description of Securities of the Company." As of June 30, 1998, an aggregate of approximately $6.2 million was available for payment of dividends by the Bank to the Company under applicable restrictions, without regulatory approval. 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. See "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Financial Condition -- Capital Resources" and "Supervision and Regulation."

DILUTION

As of June 30, 1998, the tangible book value of the Common Stock was $5.22 per share. "Tangible book value per share" represents the amount of total tangible assets less total liabilities divided by the number of shares of Common Stock outstanding. After giving effect to the Union Acquisition, including $ million of goodwill and core deposit intangibles and the sale by the Company of 925,000 shares of Common Stock offered hereby (after deducting the underwriting discount and other estimated offering expenses to be paid by the Company), the pro forma tangible book value of the Company as of June 30, 1998 would have been $ per share. This represents an immediate increase in net tangible book value of $ per share to current shareholders and an immediate dilution of $ per share to new investors. The following table illustrates this per share dilution:

PENDING ACQUISITION

GENERAL. The Company's Board of Directors actively pursues an acquisition strategy designed to increase efficiency, market share and return to shareholders. As part of this strategy, the Company has entered into a definitive agreement to acquire Union, a Texas banking association organized in 1907, pursuant to a statutory merger. Union is a single location community bank whose business includes conventional consumer and commercial products and services, including interest and noninterest-bearing depository accounts and commercial, industrial, consumer, agricultural and real estate lending. At June 30, 1998, Union had total assets of approximately $76.9 million, total deposits of approximately $63.7 million (12.9% of which were noninterest-bearing) and total shareholders' equity of approximately $12.9 million. Union is the only full-service commercial bank in East Bernard and has a stable customer base.

The Union Acquisition will be accretive to the Company's earnings immediately and provide the Company a presence in East Bernard, a community of 1,500 located in northern Wharton County. The acquisition will allow the Company to acquire a larger market share in Wharton County, where the Company's El Campo Banking Center is located. The acquisition of Union will also help the Company improve its loan mix by increasing the Company's agriculture loans as of June 30, 1998 from $8.4 million to $22.2 million on a pro forma basis. Union has a lending philosophy which is similar to that employed by the Company. The Company's significantly higher lending limit is expected to create lending opportunities in the market that Union was unable to take advantage of prior to the acquisition. Similar to its previous acquisitions, the Company believes that the Union Acquisition will enable the Company to achieve certain economies of scale and resultant savings from the operation of Union as an additional Banking Center.

ACQUISITION BY THE COMPANY. On June 5, 1998, the Company entered into an Agreement and Plan of Reorganization (the "Acquisition Agreement") with Union pursuant to which the Company will acquire all of the issued and outstanding shares of Union's common stock (the "Union Common Stock"). The

17

Acquisition Agreement provides that upon consummation of the Union Acquisition, holders of Union Common Stock will receive $17.6 million in cash as consideration in exchange for their shares of Union Common Stock. The source of the Company's funds for the acquisition will be a combination of existing cash ($15.6 million) and borrowed funds ($2.0 million). The Union Acquisition will be accounted for as a purchase transaction.

The obligations of the parties to complete the acquisition of Union are subject to certain conditions, including the conditions that: (i) all approvals of any regulatory authority having jurisdiction have been received and all applicable statutory waiting periods have expired; (ii) the shareholders of Union shall have approved the transactions contemplated under the Acquisition Agreement; and (iii) the holders of not more than 10% of the Union Common Stock shall have exercised their dissenters' rights of appraisal. In addition, the Company is not obligated to complete the acquisition of Union unless certain conditions have been satisfied by Union or waived by the Company, including that: (i) each of the representations and warranties of Union in the Acquisition Agreement shall be true in all material respects and Union shall have performed or complied with all covenants and conditions contained in the Acquisition Agreement; (ii) Union shall not have suffered any material adverse change in its financial condition, business or operations; and (iii) Union shall have used its best efforts to have the directors and officers of Union execute releases generally releasing Union from virtually all claims by such individuals. At or prior to the closing of the Union Acquisition, two executive officers of Union are expected to execute employment agreements which contain two-year non-competition clauses.

The closing date of the Union Acquisition, which management of the Company expects to occur prior to the closing of the Offering, will be selected by mutual agreement of the parties to the Acquisition Agreement following satisfaction or waiver of all conditions to closing. The closing of the Offering is not contingent upon the prior or simultaneous closing of the Union Acquisition. There can be no assurance that the foregoing conditions will be satisfied or waived or that the Union Acquisition will be completed.

NATURE OF THE TRADING MARKET

Prior to the Offering, there has been no public market for the shares of Common Stock and there can be no assurance that an active public market will develop or be sustained after the Offering or that if such a market develops, investors in the Common Stock will be able to resell their shares at or above the initial public offering price. See "Risk Factors -- No Prior Trading Market." The initial public offering price of the shares of Common Stock will be determined by negotiations between the Company and the Representatives and will not necessarily bear any relationship to the Company's book value, past operating results, financial condition or other established criteria of value and may not be indicative of the market price of the Common Stock after the Offering. Among the factors considered in such negotiations are prevailing market and general economic conditions, the market capitalizations, trading histories and stages of development of other traded companies that the Company and the Representatives believe to be comparable to the Company, the results of operations of the Company in recent periods, the current financial position of the Company, estimates of the business potential of the Company and the present state of the Company's development and the availability for sale in the market of a significant number of shares of Common Stock. Additionally, consideration will be given to the general status of the securities market, the market conditions for new issues of securities and the demand for securities of comparable companies at the time the Offering is made. See "Underwriting" for information relating to the method of determining the initial public offering price. Application has been made for quotation of the shares of Common Stock on the Nasdaq/National Market under the symbol "PRSP."

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Management's Discussion and Analysis of Financial Condition and Results of Operations of the Company 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 financial statements and accompanying notes and other detailed information appearing elsewhere in this Prospectus.

FOR THE SIX MONTHS ENDED JUNE 30, 1998 AND 1997

OVERVIEW

The twelve month period ended June 30, 1998 was marked by strong loan growth of $20.3 million or 16.8% which is attributable to one-to-four family residential loans and the Company's entrance into the home equity market. The Company showed positive earnings growth due to the increase in loan volume and the acquisition of deposits and certain assets of a branch of Wells Fargo Bank in Angleton, Texas in the second quarter of 1997 (the "Angleton Acquisition").

Net income for the six months ended June 30, 1998 was $2.1 million, which was $396,000 or 23.8% more than net income for the six months ended June 30, 1997. Diluted earnings per common share were $0.50 for the six months ended June 30, 1998 and $0.46 for the six months ended June 30, 1997. The increase in net income reflected higher net interest income and noninterest income. The increase in net interest income was driven by growth in interest-earning assets, including strong internal loan growth. Annualized return on average assets and return on average common equity were 1.25% and 15.99%, respectively, for the six months ended June 30, 1998 compared with 1.13% and 16.56%, respectively, for the same period in 1997. Return on average assets and return on average equity excluding amortization of goodwill were 1.39% and 17.82%, respectively, for the six months ended June 30, 1998 compared with 1.24% and 18.18%, respectively, for the same period in 1997. The Company's annualized efficiency ratio, calculated by dividing total noninterest expense (excluding securities losses) by net interest income plus noninterest income, was 57.53% for the six months ended June 30, 1998 and 58.83% for the six months ended June 30, 1997. The Company's efficiency ratio excluding amortization of goodwill was 54.36% for the six months ended June 30, 1998 and 56.62% for the six months ended June 30, 1997.

Total assets at June 30, 1998 increased to $335.4 million from $315.1 million at June 30, 1997, an increase of $20.3 million or 6.4%. Deposits rose to $307.8 million at June 30, 1998 from $290.3 million at June 30, 1997, an increase of $17.5 million or 6.0%. This increase was attributable to internal growth and a branch acquisition. Total shareholders' equity was $26.5 million at June 30, 1998, representing an increase of $3.3 million or 14.2% over total shareholders' equity of $23.2 million at June 30, 1997.

RESULTS OF OPERATIONS

NET INTEREST INCOME

Net interest income represents the amount by which interest income on interest-earning assets, including securities and loans, exceeds interest expense incurred on interest-bearing liabilities, including deposits and other borrowed funds. Net interest income is the principal source of the Company's earnings. Interest rate fluctuations, as well as changes in the amount and type of earning assets and liabilities, combine to affect net interest income.

Net interest income for the six months ended June 30, 1998 was $6.2 million compared with $5.2 million for the six months ended June 30, 1997, an increase of $1.0 million or 19.2%. The Company's net interest margin on a tax-equivalent basis was 4.15% and 3.95% and net interest spread was 3.19% and 3.06% for the periods ended June 30, 1998 and June 30, 1997, respectively. Net interest income increased as a result of an increase in interest-earning assets derived primarily from growth in loans and securities. Loans increased to $141.1 million for the six months ended June 30, 1998 from $120.8 million for the six months ended June 30, 1997, an increase of $20.3 million or 16.8%. Home equity loans accounted for a significant portion of this growth.

25

The increase in the net interest margin for the first half of 1998 compared with the first half of 1997 reflects a three basis point increase in the yield on average interest-earning assets and a 10 basis point decrease in the cost of interest-bearing liabilities. The yield on average interest-earning assets increased to 7.15% for the six months ended June 30, 1998 from 7.12% for the six months ended June 30, 1997, due primarily to higher-yielding loans and securities. The cost of interest-bearing liabilities decreased to 3.96% for the six months ended June 30, 1998 from 4.06% for the six months ended June 30, 1997, due mainly to the lower cost of the funds acquired in the Angleton Acquisition.

The following table presents for the periods indicated the total dollar amount of average balances, interest income from average interest-earning assets and the resultant yields, as well as the interest expense on average interest-bearing liabilities, expressed both in dollars and rates. Except as indicated in the footnotes, no tax-equivalent adjustments were made and all average balances are daily average balances.

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

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

(3) In order to make pre-tax income and resultant yields on tax-exempt investments and loans comparable to those on taxable investments and loans, a tax-equivalent adjustment has been computed using a federal income tax rate of 34%.

The following schedule presents the dollar amount of changes in interest income and interest expense for the major components of interest-earning assets and interest-bearing liabilities and distinguishes between the increase related to higher outstanding balances and the volatility of 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 provision for credit losses increased to $144,500 for the six months ended June 30, 1998 from $105,000 for the same time period in 1997, an increase of $39,500 or 37.6%. The Company had no nonperforming assets at June 30, 1998.

NONINTEREST INCOME

Noninterest income is an important source of revenue for financial institutions. The Company's primary source of noninterest income is service charges on deposit accounts. Noninterest income for the six months ended June 30, 1998 was $1.2 million, an increase of $229,000 or 22.7% from $1.0 million for the same period in 1997 resulting largely from increased fees from service charges.

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

Service charges on deposit accounts are the largest component of noninterest income and a significant source of revenue to the Company. The increase in service charges on deposit accounts and total noninterest income for the first six months of 1998 compared with the first six months of 1997 resulted mainly from the increase in the number and volume of accounts resulting from the Angleton Acquisition.

NONINTEREST EXPENSE

In the six month period ended June 30, 1998, noninterest expense increased $588,000 or 16.0% to $4.3 million from $3.7 million for the period ended June 30, 1997. The increase reflected additional expenses resulting from the Angleton Acquisition.

Salaries and employee benefits for the six months ended June 30, 1998 was $2.1 million, an increase of $214,000 or 11.3% from $1.9 million in the same period of 1997. The increase was principally due to additional staff associated with the Angleton Acquisition.

Non-staff expenses increased to $2.1 million for the six month period ended June 30, 1998 from $1.8 million for the same period in 1997, an increase of $374,000 or 21.1%. This increase also was largely due to additional expenses associated with the Angleton Acquisition.

INCOME TAXES

Income tax expense includes the regular federal income tax at the statutory rate plus the income tax component of the Texas franchise tax. The amount of federal income tax expense is influenced by the amount of taxable income, the amount of tax-exempt income, the amount of non-deductible interest expense and the amount of other non-deductible expenses. Taxable income for the income tax component of the Texas franchise tax is the federal pre-tax income, plus certain officers' salaries, less interest income on federal securities. The income tax component of the Texas franchise tax was zero in the first six months of 1998 and 1997. During the six months ended June 30, 1998, income tax expense was $939,000 compared with $756,000 for the six months ended June 30, 1997. The effective tax rate for both the six months ended June 30, 1998 and 1997 was 31.3%.

IMPACT OF INFLATION

The effects of inflation on the local economy and on the Company's operating results have been relatively modest for the past several years. Since substantially all of the Company's assets and liabilities are monetary in nature, such as cash, securities, loans and deposits, their values are less sensitive to the effects of inflation than to changing interest rates, which do not necessarily change in accordance with inflation rates. The Company tries to control the impact of interest rate fluctuations by managing the relationship between its interest rate sensitive assets and liabilities. See "-- Financial Condition -- Interest Rate Sensitivity and Liquidity."

FINANCIAL CONDITION

LOAN PORTFOLIO

Loans, net of unearned interest, were $141.1 million at June 30, 1998, an increase of $20.3 million or 16.8% from $120.8 million at June 30, 1997. The increase was principally due to loans generated under the Company's new home equity loan program and one-to-four family residential loans. The State of Texas passed legislation approving home equity lending effective January 1, 1998. The Company makes home equity loans in amounts up to 80% of the appraised value. At June 30, 1998, home equity loans totaled $4.7 million. In addition to offering competitive mortgage rates, the Company marketed a new 15-year loan product which resulted in an increase in one-to-four family residential loans during the period. Construction and land development loans were $9.4 million at June 30, 1998, an increase of $3.1 million or 49.7% from $6.3 million at June 30, 1997. Growth was primarily due to new home construction in the Houston market.

The lending focus of the Company is on one-to-four family residential, agricultural, small and medium-sized business and consumer loans. The Company offers a variety of commercial lending products including term loans and lines of credit. A broad range of short to medium-term commercial loans, primarily collateralized, are made available 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. The purpose of a particular loan generally determines its structure. All loans in the one-to-four family residential category were originated by the Company.

Loans from $200,000 to $500,000 are evaluated and acted upon by an officers' loan committee, which meets weekly. Loans above that amount must be approved by the Directors Loan Committee, which meets monthly.

Generally, the Company's commercial loans are made in the Company's primary market area and are underwritten on the basis of the borrower's ability to service such 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. Working capital loans are primarily collateralized by short-term assets whereas term loans are primarily collateralized by long-term assets.

In addition to commercial loans secured by real estate, the Company makes commercial mortgage loans to finance the purchase of real property which generally consists of real estate with completed structures. Additionally, a portion of the Company's lending activity has consisted of the origination of one-to-four family residential mortgage loans collateralized by owner-occupied properties located in the

29

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 one-to-four family residential real estate generally have been originated in amounts of no more than 89% of appraised value or have mortgage insurance. The Company requires mortgage title insurance and hazard insurance. The Company's commercial mortgage loans are secured by first liens on real estate, typically have variable interest rates and amortize over a ten to 15 year period. In underwriting commercial mortgage loans, consideration is given to the property's operating history, future operating projections, current and projected occupancy, location and physical condition. The underwriting analysis also includes credit verification, appraisals and a review of the financial condition of the borrower.

The Company makes loans to finance the construction of residential and, to a limited extent, nonresidential properties. Construction loans generally are secured 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. In keeping with the community-oriented nature of its customer base, the Company provides construction and permanent financing for churches located within its market area.

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.

The contractual maturity ranges of the commercial and industrial and construction and land development portfolios and the amount of such loans with predetermined interest rates and floating interest rates in each maturity range as of June 30, 1998 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. 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 has historically had strong asset quality. There were no nonperforming assets (nonaccrual loans, restructured loans and other real estate) at June 30, 1998 compared with $144,000 at June 30, 1997 which consisted of a single one-to-four family property which was sold later in the year at a loss of $8,500. The Company records real estate acquired by foreclosure at the lesser of the outstanding loan balance or the fair value at the time of foreclosure, less estimated costs to sell.

The Company requires appraisals on loans secured 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.

30

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 all loans before attaining nonacccrual status.

The following table presents information regarding nonperforming assets at June 30, 1998 and June 30, 1997:

ALLOWANCE FOR CREDIT LOSSES

The allowance for credit losses is a reserve established through charges to earnings in the form of a provision for credit losses. Management has established an allowance for credit losses which it believes is adequate for estimated losses in the Company's loan portfolio. Based on an evaluation of the loan portfolio, management presents a monthly review of the allowance for credit losses to the Bank's Board of Directors, indicating any change in the allowance since the last review and any recommendations as to adjustments in the allowance. In making its evaluation, management considers the diversification by industry of the Company's commercial loan portfolio, the effect of changes in the local real estate market on collateral values, the results of recent regulatory examinations, the effects on the loan portfolio of current economic indicators and their probable impact on borrowers, the amount of charge-offs for the period, the amount of nonperforming loans and related collateral security, the evaluation of its loan portfolio by the loan review function and the annual examination of the Company's financial statements by its independent auditors. Charge-offs occur when loans are deemed to be uncollectible.

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 internally classified loan list 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. Loans classified as "substandard" are those loans with clear and defined weaknesses such as a highly-leveraged position, unfavorable financial ratios, uncertain repayment sources or poor financial condition, which may jeopardize recoverability of the debt. Loans classified as "doubtful" are those loans which have characteristics similar to substandard accounts but with an increased risk that a loss may occur, or at least a portion of the loan may require a charge-off if liquidated at present. Loans classified as "loss" are those loans which are in the process of being charged off.

In addition to the internally classified loan list and delinquency list of loans, the Company maintains a separate "watch list" which further aids the Company in monitoring loan portfolios. Watch list loans have one or more deficiencies that require attention in the short term or pertinent ratios of the loan account that have weakened to a point where more frequent monitoring is warranted. These loans do not have all of the characteristics of a classified loan (substandard or doubtful) but do show weakened elements compared with those of a satisfactory credit. The Company reviews these loans to assist in assessing the adequacy of the allowance for credit losses.

In order to determine the adequacy of the allowance for credit losses, management considers the risk classification or delinquency status of loans and other factors, such as collateral value, portfolio composition, trends in economic conditions and the financial strength of borrowers. Management establishes specific allowances for loans which management believes require reserves greater than those allocated according to their classification or delinquent status. An unallocated allowance is also established based on

the Company's historical charge-off experience. 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.

For the six months ended June 30, 1998, net charge-offs totaled $47,000 or 0.04% of average loans outstanding for the period, compared with $72,000 in net charge-offs or 0.06% of average loans outstanding for the six months ended June 30, 1997. The majority of the charge-offs were loans acquired in acquisitions. During the six months ended June 30, 1998, the Company recorded a provision for credit losses of $144,500 compared with $105,000 for the six months ended June 30, 1997. At June 30, 1998, the allowance totaled $1.1 million, or 0.79% of total loans.

The Company believes that the allowance for credit losses at June 30, 1998 is adequate to cover losses inherent in the 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 June 30, 1998.

SECURITIES

The Company uses its securities portfolio both as a source of income and as a source of liquidity. At June 30, 1998, investment securities totaled $158.7 million, an increase of $739,000 from $158.0 million at June 30, 1997. At June 30, 1998, investment securities represented 47.3% of total assets, compared with 50.1% of total assets at June 30, 1997. The yield on the investment portfolio for the six months ended June 30, 1998 was 6.09% compared with a yield of 6.06% for the six months ended June 30, 1997.

Mortgage-backed securities are securities which have been developed by pooling a number of real estate mortgages and are principally issued by federal agencies such as the Federal National Mortgage Association and the Federal Home Loan Mortgage Corporation. 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.

At June 30, 1998, 30.0% of the mortgage-backed securities held by the Company had contractual final maturities of more than ten years with a weighted average life of 3.1 years. However, 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 not be unduly shortened. If interest rates begin to fall, prepayments will increase.

The following table summarizes the contractual maturity of investment securities (including federal funds sold) and their weighted average yields. Available-for-sale securities are not adjusted for unrealized gains or losses.

The Company has adopted Statement of Financial Accounting Standards ("SFAS") No. 115, ACCOUNTING FOR CERTAIN INVESTMENTS IN DEBT AND EQUITY SECURITIES ("SFAS 115"). 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

34

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.

DEPOSITS

The Company offers a variety of deposit accounts having a wide range of interest rates and terms. The Company's deposits consist of demand, savings, money market and time accounts. The Company relies primarily on competitive pricing policies and customer service to attract and retain these deposits. The Company does not have any brokered deposits.

The Company's average total deposits for the six months ended June 30, 1998 were $300.9 million or 12.0% over average total deposits during the same period in 1997. The Company's total deposits at June 30, 1998, were $307.8 million, up $17.6 million or 6.1% over total deposits at June 30, 1997. The increase in deposits is attributable to internal growth.

The Company's lending and investing activities are funded principally by deposits, approximately 61.5% of which are demand and savings deposits. Average noninterest-bearing deposits at June 30, 1998 increased to $65.3 million compared with $53.1 million for the first six months of 1997, an increase of $12.2 million or 23.0% over 1997. Approximately 21.7% of the average deposits were noninterest-bearing for the six months ended June 30, 1998. As a result, the Company had a total cost of deposits of 3.11%.

The daily average balances and weighted average rates paid on interest-bearing deposits for the period ended June 30, 1998 are presented below:

OTHER BORROWINGS

Deposits are the primary source of funds for the Company's lending and investment activities. Occasionally, the Company obtains additional funds from the Federal Home Loan Bank ("FHLB") and correspondent banks. During 1997, the Company entered into an agreement with another commercial bank to borrow up to $8.0 million under a reducing, revolving line of credit (the "Line.") At June 30, 1998, the Company had no borrowings under the Line compared with $865,000 under a previous line of credit at June 30, 1997.

INTEREST RATE SENSITIVITY AND LIQUIDITY

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.

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: (i) an analysis of relationships between interest-earning assets and interest-bearing liabilities; and (ii) an interest rate shock simulation model. The Company has traditionally managed its business to reduce its overall exposure to changes in interest rates.

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.

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.

Shortcomings are inherent in any GAP analysis since certain assets and liabilities may not move proportionally as interest rates change. 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. Based on the Company's June 30, 1998 simulation analysis, the Company estimates that a 200 basis point rise or decline in rates over the next 12 month period would have an impact of less than 6% on its net interest income for the period. The change is relatively small, despite the Company's liability sensitive GAP position. The results are primarily from the behavior of demand, money market and savings deposits. The Company has found that historically interest rates on these deposits change more slowly in a rising rate environment than in a declining rate environment. This assumption is incorporated into the simulation model and is generally not fully reflected in a GAP analysis. The Company maintains an Investment Committee that reviews the Company's interest rate risk position, generally on a quarterly basis.

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. 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 market risk is reviewed on a regular basis. 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. Management realizes certain risks are inherent, and that the goal is to identify and accept the risks.

Liquidity involves the Company's ability to raise funds to support asset growth or reduce assets to meet deposit withdrawals and other payment obligations, to maintain reserve requirements and otherwise to operate the Company on an ongoing basis. During the past three years, the Company's liquidity needs have primarily been met by growth in core deposits, as previously discussed. Although access to purchased funds from correspondent banks is available and has been utilized on occasion to take advantage of investment

37

opportunities, the Company does not generally rely on these external funding sources. The cash and federal funds sold position, supplemented by amortizing investment and loan portfolios, have generally created an adequate liquidity position.

CAPITAL RESOURCES

Capital management consists of providing equity to support both 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 and the Texas Banking Department. 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-adjusted 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 assets ("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% to 5.0%. 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 Federal Deposit Insurance Corporation Improvement Act of 1991 ("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. See "Supervision and Regulation -- The Company" and "-- the Bank."

Shareholders' equity increased from $23.2 million at June 30, 1997 to $26.5 million at June 30, 1998, an increase of $3.3 million or 14.2%. This increase was primarily the result of net income of $4.0 million, less dividends paid on Common Stock of approximately $800,000.

YEAR 2000 COMPLIANCE

The Company formally initiated its Year 2000 project in November 1997 to insure that its operational and financial systems will not be adversely affected by Year 2000 problems. The Company has formed a Year 2000 project team and the Board of Directors and management are supporting all compliance efforts and allocating the necessary resources to ensure completion. An inventory of all systems and products (including both information technology and non-informational technology systems) that could be affected by the Year 2000 date change has been developed, verified and categorized as to its importance to the Company. The software for the Company's systems is provided through service bureaus and software vendors. The Company has contacted all of its third party vendors and software providers and is requiring them to demonstrate and represent that the products provided are or will be Year 2000 compliant and has planned a program of testing compliance. The service bureau has asserted that it is Year 2000 compliant and pursuant to applicable regulatory guidelines the Company is currently testing its system to verify this assertion. The Company has also surveyed its largest dollar deposit and loan customers to determine their readiness for Year 2000.

Management does not expect the costs of bringing the Company's systems into Year 2000 compliance will have a material adverse effect on the Company's financial conditions, results of operations or liquidity. The Company has budgeted $10,000 to address Year 2000 issues. As of June 30, 1998, the Company has not incurred any significant costs in relation to Year 2000. The largest potential risk to the Company concerning Year 2000 is the malfunction of its data processing system. In the event its data processing system does not function properly, the Company is prepared to perform functions manually. The Company believes it is in compliance with regulatory guidelines regarding Year 2000 compliance, including the timetable for achieving compliance.

FOR THE YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995

OVERVIEW

Net income was $3.6 million, $2.7 million and $2.3 million for the years ended December 31, 1997, 1996 and 1995, respectively, and diluted earnings per share were $0.92, $0.76 and $0.66 for these same periods. Earnings growth from 1995 to 1996 and from 1996 to 1997 resulted principally from loan growth and branch acquisitions. The Company posted returns on average assets of 1.17%, 1.05% and 1.03% and returns on average equity of 16.32%, 15.36% and 15.56% for the years ended 1997, 1996 and 1995, respectively. The Company posted returns on average assets excluding amortization of goodwill of 1.30%, 1.15% and 1.13% and returns on average equity excluding amortization of goodwill of 18.17%, 16.82% and 16.96% for the years ended December 31, 1997, 1996 and 1995, respectively. The Company's efficiency ratio was 59.48% in 1997, 61.34% in 1996 and 64.85% in 1995. The Company's efficiency ratio excluding amortization of goodwill was 56.43% in 1997, 58.96% in 1996 and 62.61% in 1995.

Total assets at December 31, 1997, 1996 and 1995 were $320.1 million, $294.0 million and $233.5 million, respectively. Total deposits at December 31, 1997, 1996 and 1995 were $291.5 million, $270.9 million and $214.5 million, respectively, with deposit growth in each period resulting largely from the branch acquisitions in 1996 and 1997. Loans were $120.6 million at December 31, 1997, an increase of $7.2 million or 6.3% from $113.4 million at the end of 1996. Loans were $88.8 million at year end 1995. Shareholders' equity was $24.8 million, $18.8 million and $16.5 million at December 31, 1997, 1996 and 1995, respectively.

RESULTS OF OPERATIONS

NET INTEREST INCOME

1997 VERSUS 1996. Net interest income for 1997 was $10.9 million, compared with $8.9 million for 1996, an increase of $2.0 million or 22.5%. The improvement in net interest income for 1997 was mainly due to an increase in total interest-earning assets, primarily in the loan portfolio. During 1997, the yield on interest-earning assets increased eight basis points from 7.08% in 1996 to 7.16% in 1997 primarily due to an increase in the volume of higher-yielding loans. Total funding costs decreased seven basis points from 4.11% in 1996 to 4.04% in 1997 primarily due to an increase in noninterest-bearing deposits. For 1997, the net interest margin on a tax-equivalent basis increased 11 basis points to 4.02% from 3.91% in 1996.

1996 VERSUS 1995. Net interest income for the Company in 1996 was $8.9 million, an increase of 14.1% over the 1995 level of $7.8 million, due to an increase in the loan portfolio in 1996. For 1996 as a whole, the Company's net interest expense increased eight basis points from 4.03% to 4.11% while asset yields increased two basis points from 7.06% to 7.08%.

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

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

(3) In order to make pre-tax income and resultant yields on tax-exempt investments and loans comparable to those on taxable investments and loans, a tax-equivalent adjustment has been computed using a federal income tax rate of 34%.

The following schedule presents the dollar amount of changes in interest income and interest expense for the major components of interest-earning assets and interest-bearing liabilities and distinguishes between the increase related to higher outstanding balances and the volatility of interest rates. For purposes of this table, changes attributable to both rate and volume which can not be segregated have been allocated to rate.

PROVISION FOR CREDIT LOSSES

The allowance for credit losses at December 31, 1997 was $1.0 million, representing 0.84% of outstanding loans. One year earlier, this ratio was 0.81% of outstanding loans. The provision for credit losses charged against earnings was $190,000 in 1997 compared with $230,000 in 1996. The Company recorded a lower provision in 1997 because it had specific reserves in the amount of $45,000 which were no longer necessary due to the repayment of the related loans. Net loans charged off in 1997 were $97,000 compared with $60,000 in 1996.

During 1996, the Company made provisions totaling $230,000 to the allowance for credit losses, an increase of $55,000 compared with 1995.

NONINTEREST INCOME

For 1997, noninterest income totaled $2.3 million, an increase of $367,000 or 19.3% versus $1.9 million in 1996. The increase was primarily due to the branch acquisitions in Bay City and Angleton and an increase in customer service fees. Noninterest income for 1996 was $1.9 million, a $408,000 or 27.4% increase from 1995 resulting largely from an increase in income from insufficient funds charges and customer service fees.

The Company has adopted Statement of Accounting Standards No. 114, ACCOUNTING FOR CREDITORS FOR IMPAIRMENT OF A LOAN ("SFAS 114"), as amended by
Statement of Accounting Standards No. 118, ACCOUNTING BY CREDITORS FOR
IMPAIRMENT OF A LOAN-INCOME RECOGNITION AND DISCLOSURES. Under SFAS No. 114, as amended, a loan is considered impaired based on current information and events, if it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. The fair value of impaired loans is based on the present value of expected future cash flows discounted at the loan's effective interest rate or the loan's observable market price or based on the fair value of the collateral if the loan is collateral-dependent. The implementation of SFAS Nos. 114 and 118 did not have a material adverse affect on the Company's financial statements.

NONPERFORMING ASSETS

The Company's conservative lending approach, as well as a healthy local economy, has resulted in strong asset quality. The Company had no nonperforming assets as of December 31, 1997, 1996 or 1995.

At December 31, 1997, investment securities of $167.9 million increased $20.3 million from $147.6 million at December 31, 1996, as the Company invested excess deposits from the Angleton Acquisition. At December 31, 1997, investment securities represented 57.6% of total deposits and 52.4% of total assets. Approximately $66.4 million or 40.0% of the Company's investment securities reprice within one year.

Investment securities increased from $117.5 million at December 31, 1995 to $147.6 million at December 31, 1996, largely due to the Bay City branch acquisition.

Bayne, Bouligny and Steelhammer are Class II directors with terms of office expiring on the date of the Company's annual meeting of shareholders in 2000; and Messrs. Rudolph and Zalman are Class III directors with terms of office expiring on the date of the Company's annual meeting of shareholders in 2001. Each officer of the Company is elected by the Board of Directors of the Company and holds office until his successor is duly elected and qualified or until his or her earlier death, resignation or removal.

The Board of Directors has established Audit and Compensation Committees. The Audit Committee reviews the general scope of the audit conducted by the Company's independent auditors and matters

52

relating to the Company's internal control systems. In performing its function, the Audit Committee meets separately with representatives of the Company's independent auditors and with representatives of senior management. The Audit Committee is composed of Messrs. Bayne, Bouligny and Steelhammer, all of whom are outside directors.

The Compensation Committee is responsible for making recommendations to the Board of Directors with respect to the compensation of the Company's executive officers and is responsible for the establishment of policies dealing with various compensation and employee benefit matters. The Compensation Committee also administers the Company's stock option plans and makes recommendations to the Board of Directors as to option grants to Company employees under such plans. The Compensation Committee is comprised of Messrs. Bayne, Bouligny, Herin, Slavik, Stafford and Steelhammer, all of whom are outside directors.

EMPLOYMENT AGREEMENTS

Tracy T. Rudolph and David Zalman have entered into employment agreements with the Company. Each agreement is for a term of three years and automatically renews each year unless terminated in accordance with its terms. The employment agreements provide that if the employee is terminated without cause (including constructive termination) or if a change in control of the Company occurs, the employee shall be entitled to receive from the Company a lump sum payment equal to three years' base salary.

DIRECTOR COMPENSATION

Directors of the Company receive a $1,250 fee for each Board meeting attended and no fees for each committee meeting attended. Directors of the Bank receive a $350 fee for each Board meeting attended and $300 for each committee meeting attended.

STOCK OPTION PLANS

The Company has outstanding options to purchase 320,000 shares of Common Stock issued pursuant to a stock option plan approved by the shareholders in 1995 (the "1995 Plan") for executive officers and directors. Under the 1995 Plan, the options vest ratably over a ten year period beginning on the date of the grant; however, no options may be exercised until the optionee has completed five years of employment with the Company after the date of the grant. The options were granted at an average exercise price of $4.75. Compensation expense was not recognized for the options because the options had an exercise price approximating the fair value of the Common Stock at the time of the grant. No options granted under the 1995 Plan will be exercisable until May 31, 2000. Options to purchase an additional 20,000 shares are available for issuance under the 1995 Plan.

The Company's Board of Directors and shareholders approved a new stock option plan in 1998 (the "1998 Plan") which authorizes the issuance of up to 460,000 shares of Common Stock under both "non-qualified" and "incentive stock" options to employees and "non-qualified" stock options to directors who are not employees. Generally, under the 1998 Plan it is intended that the options will vest 60% at the end of the third year following the date of grant and an additional 20% at the end of each of the two following years; however, an individual option may vest as much as 20% at the end of the first or second year following the date of grant if necessary to maximize the "incentive" tax treatment to the optionee for the particular option being granted. Options under the 1998 Plan generally must be exercised within 10 years following the date of grant or no later than three months after optionee's termination with the Company, if earlier. No options have been granted under the 1998 Plan. The 1998 Plan provides that in the event of a change in control of the Company, all options granted immediately vest and become exercisable.

In October 1995, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 123, ACCOUNTING FOR STOCK-BASED COMPENSATION ("SFAS 123"). This statement established fair value based accounting and reporting standards for all transactions in which a company acquires goods or services by issuing its equity investments, which includes stock-based compensation plans. Under SFAS 123, compensation cost is measured at the grant date based on the value of the award and is recognized over the service period, which is usually the vesting period. Fair value of stock options is determined using an option-pricing model. This statement encourages companies to adopt as prescribed the fair value based method of accounting to recognize compensation expense for employee stock compensation plans. However, it does not require the fair value based method to be adopted but a company must comply with the disclosure requirements set forth in the statement. The Company has continued to apply Accounting Principles Board Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES, ("APB 25") and related Interpretations, and, accordingly, will provide the pro forma disclosures of net income and earnings per share.

OPTIONS GRANTED DURING 1997

The Company did not grant any options to its executive officers during 1997.

BENEFIT PLAN

The Company has established a contributory profit sharing plan (the "Plan") pursuant to Internal Revenue Code Section 401(k) covering substantially all employees. At least one year of service is required to be eligible for employer-matching contributions. Participants may contribute up to 15% of their compensation to the Plan. Each year the Company determines, at its discretion, the amount of matching contributions. Total Plan expense charged to the Company's operations for 1997 and 1996 was approximately $87,000 and $72,000, respectively. The Company has expensed $48,000 for 1998 contributions during the period ended June 30, 1998.

INTERESTS OF MANAGEMENT AND OTHERS IN CERTAIN TRANSACTIONS

Many of the directors, executive officers and principal shareholders of the Company (I.E., those who own 10% or more of the Common Stock) and their associates, which include corporations, partnerships and other organizations in which they are officers or partners or in which they and their immediate families have

54

at least a 5% interest, are customers of the Company. During 1997, the Company made loans in the ordinary course of business to many of the directors, executive officers and principal shareholders of the Company and their associates, all of which were on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with persons unaffiliated with the Company and did not involve more than the normal risk of collectibility or present other unfavorable features. Loans to directors, executive officers and principal shareholders of the Company are subject to limitations contained in the Federal Reserve Act, the principal effect of which is to require that extensions of credit by the Company to executive officers, directors and principal shareholders satisfy the foregoing standards. On June 30, 1998, all of such loans aggregated $3.0 million, which was approximately 0.01% of the Company's Tier 1 capital at such date.

The Company expects to have such transactions or transactions on a similar basis with its directors, executive officers and principal shareholders and their associates in the future.

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 funds of the 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 herein 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 bank holding company registered under the BHCA, and it is subject to supervision, regulation and examination by the Federal Reserve Board. The BHCA and other federal laws subject 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.

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, and any claim for breach of such obligation will generally have priority over most other unsecured claims.

ACTIVITIES "CLOSELY RELATED" TO BANKING. The BHCA prohibits a bank holding company, with certain limited exceptions, from acquiring direct or indirect ownership or control of any voting shares of any company which is not a bank or from engaging in any activities other than those of banking, managing or controlling banks and certain other subsidiaries, or furnishing services to or performing services for its subsidiaries. One principal exception to these prohibitions allows the acquisition of interests in companies whose activities are found by the Federal Reserve Board, by order or regulation, to be so closely related to banking or managing or controlling banks, as to be a proper incident thereto. Some of the activities that have been determined by regulation to be closely related to banking are making or servicing loans, performing certain data processing services, acting as an investment or financial advisor to certain investment trusts and investment companies, and providing securities brokerage services. Other activities approved by the Federal Reserve Board include consumer financial counseling, tax planning and tax preparation, futures and options advisory services, check guaranty services, collection agency and credit bureau services, and personal property appraisals. In approving acquisitions by bank holding companies of companies engaged in banking-related activities, the Federal Reserve Board considers a number of factors, and weighs the expected benefits to the public (such as greater convenience and increased competition or gains in efficiency) against the risks of possible adverse effects (such as undue concentration of resources, decreased or unfair competition, conflicts of interest, or unsound banking practices). The Federal Reserve

57

Board is also empowered to differentiate between activities commenced de novo and activities commenced through acquisition of a going concern.

SECURITIES ACTIVITIES. The Federal Reserve Board has approved applications by bank holding companies to engage, through nonbank subsidiaries, in certain securities-related activities (underwriting of municipal revenue bonds, commercial paper, consumer receivable-related securities and one-to-four family mortgage-backed securities), provided that the affiliates would not be "principally engaged" in such activities for purposes of Section 20 of the Glass-Steagall Act. In limited situations, holding companies may be able to use such subsidiaries to underwrite and deal in corporate debt and equity securities.

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 $1,000,000 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 total risk-based capital ratio 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 June 30, 1998, the Company's ratio of Tier 1 capital to total risk-weighted assets was 14.32% and its ratio of total capital to total risk-weighted assets was 15.08%. See "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Financial Condition -- Capital Resources."

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 consolidated assets. Certain highly-rated bank holding companies may maintain a minimum leverage ratio of 3.0%, but other bank holding companies may be required to maintain a leverage ratio of up to 200 basis points above the regulatory minimum. As of June 30, 1998, the Company's leverage ratio was 6.25%.

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.

58

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 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.

CONTROL ACQUISITIONS. The Change in Bank Control Act 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% of 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, any entity is required to obtain the approval of the Federal Reserve Board under the BHCA before acquiring 25% (5% in the case of an acquiror that is a bank holding company) or more of the outstanding Common Stock of the Company, or otherwise obtaining control or a "controlling influence" over the Company.

THE BANK

The Bank is a Texas-chartered banking association, the deposits of which are insured by the Bank Insurance Fund ("BIF"). 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 subjects 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.

59

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 subsidiaries, 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 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 upon 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.

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 institution's holding company can be used to satisfy this requirement. Auditors must receive examination reports, supervisory agreements and reports of enforcement actions. In addition, 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

60

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 risk-weighted assets of 4.0% and a ratio of total capital to total risk-weighted assets of 8.0%. The capital categories have the same definitions for the Bank as for the Company. As of June 30, 1998, the Bank's ratio of Tier 1 capital to total risk-weighted assets was 14.22% and its ratio of total capital to total risk-weighted assets was 14.99%. See "Management's Discussion and Analysis of Financial Condition and Result of Operation of the Company -- Financial Condition -- Capital Resources."

The FDIC's leverage guidelines require state banks to maintain Tier 1 capital of no less than 5.0% of average total 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 6%. As of June 30, 1998, the Bank's ratio of Tier 1 capital to average total assets (leverage ratio) was 6.21%. See "Management's Discussion and Analysis of Financial Condition and Result of Operation of the Company -- Financial Condition -- Capital Resources."

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.

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.

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 federal deposit insurance protection. The FDIC has adopted a risk-based assessment system as required by FDICIA. Under

61

this system, FDIC-insured depository institutions pay 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 the regulators. In addition, the FDIC can impose special assessments in certain instances.

The FDIC established a process for raising or lowering all rates for insured institutions semi-annually if conditions warrant a change. Under this new system, the FDIC has the flexibility to adjust the assessment rate schedule twice a year without seeking prior public comment, but only within a range of five cents per $100 above or below the premium schedule adopted. Changes in the rate schedule outside the five cent range above or below the current schedule can be made by the FDIC only after a full rulemaking with opportunity for public comment.

On September 30, 1996, President Clinton signed into law an act that contained a comprehensive approach to recapitalizing the SAIF and to assure the payment of the Financing Corporation's ("FICO") bond obligations. Under this new act, banks insured under the BIF are required to pay a portion of the interest due on bonds that were issued by FICO to help shore up the ailing Federal Savings and Loan Insurance Corporation in 1987. The BIF rate must equal one-fifth of the SAIF rate through year-end 1999, or until the insurance funds are merged, whichever occurs first. Thereafter BIF and SAIF payers will be assessed pro rata for the FICO bond obligations. With regard to the assessment for the FICO obligation, the current BIF rate is .0126% of deposits and the SAIF rate is .0630% of deposits.

ENFORCEMENT POWERS. The FDIC and the other 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 its banking subsidiaries, as well as officers, directors and other institution-affiliated parties of these organizations, to administrative sanctions and potentially substantial civil money penalties. 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.

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 such 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 Community Reinvestment Act of 1977 ("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, 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.

62

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.

INSTABILITY OF REGULATORY STRUCTURE

Various legislation, including proposals to overhaul the bank regulatory system, expand the powers of banking institutions and bank holding companies and limit the investments that a depository institution may make with insured funds, is from time to time introduced in Congress. Such legislation 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 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.

EXPANDING ENFORCEMENT AUTHORITY

One of the major additional burdens imposed on the banking industry by FDICIA is the increased ability of banking regulators to monitor the activities of banks and their holding companies. In addition, the Federal Reserve Board and FDIC are possessed of extensive authority to police unsafe or unsound practices and violations of applicable laws and regulations by depository institutions and their holding companies. For example, the FDIC may terminate the deposit insurance of any institution which it determines has engaged in an unsafe or unsound practice. The agencies can also assess civil money penalties, issue cease and desist or removal orders, seek injunctions, and publicly disclose such actions. FDICIA, FIRREA and other laws have expanded the agencies' authority in recent years, and the agencies have not yet fully tested the limits of their powers.

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.

DESCRIPTION OF SECURITIES OF THE COMPANY

AUTHORIZED CAPITAL STOCK

The authorized capital stock of the Company consists of (i) 20,000,000 shares of preferred stock, $1.00 per share par value ("Preferred Stock"), issuable in series, none of which are issued and outstanding and (ii) 50,000,000 shares of Common Stock, $1.00 per share par value, of which 3,993,884 shares were issued and 3,990,308 shares were outstanding as of June 30, 1998. The terms of any new series of preferred stock may be fixed by the Board of Directors of the Company within certain limits set by the Company's Articles of Incorporation.

The following discussion of the terms and provisions of the Company's capital stock is qualified in its entirety by reference to the Company's Articles of Incorporation and Bylaws, copies of which have been filed as exhibits to the Registration Statement of which this Prospectus is a part.

PREFERRED STOCK

The Company is authorized to issue 20,000,000 shares of Preferred Stock. The Preferred Stock (or other securities convertible in whole or in part into Preferred Stock) is available for issuance from time to time for various purposes as determined by the Company's Board of Directors, including, without limitation, making future acquisitions, raising additional equity capital and financing. Subject to certain limits set by the Company's Articles of Incorporation, the Preferred Stock (or such convertible securities) may be issued on such terms and conditions, and at such times and in such situations, as the Board of Directors in its sole discretion determines to be appropriate, without any further approval or action by the shareholders (unless otherwise required by laws, rules, regulations or agreements applicable to the Company).

Moreover, except as otherwise limited by the Articles of Incorporation or applicable laws, rules or regulations, the Board of Directors has the sole authority to determine the relative rights and preferences of the Preferred Stock and any series thereof without shareholder approval. The Company's Articles of Incorporation require all shares of Preferred Stock to be identical, except as to the following characteristics, which may vary between different series of Preferred Stock:

(i) dividend rate, preference of dividend with respect to any other class or series of stock, and cumulativity, non-cumulativity or partial cumulativity of dividends;

(ii) redemption price and terms, including, to the extent permitted by law, the manner in which shares are to be chosen for redemption if less than all the shares of a series are to be redeemed;

(iii) sinking fund provisions for the redemption or purchase of shares;

(iv) the amount payable upon shares in the event of voluntary or involuntary liquidation;

(v) the terms and conditions on which shares may be converted, if the shares of any series are issued with the privilege of conversion;

(vi) voting rights; and

(vii) such other powers, preferences and rights as the Board of Directors shall determine.

The Board of Directors does not intend to seek shareholder approval prior to any issuance of Preferred Stock or any series thereof, unless otherwise required by law. Under the Texas Business Corporation Act ("TBCA"), shareholder approval prior to the issuance of shares of Common Stock or Preferred Stock is required in connection with certain mergers. Frequently, opportunities arise that require prompt action, such as the possible acquisition of a property or business or the private sale of securities, and it is the belief of the Board of Directors that the delay necessary for shareholder approval of a specific issuance could be to the detriment of the Company and its shareholders. The Board of Directors does not intend to issue any shares of Common Stock or Preferred Stock except on terms which the Board of Directors deems to be in the best interests of the Company and its then existing shareholders.

64

Although the Preferred Stock could be deemed to have an anti-takeover effect, the Board of Directors is not aware of any takeover efforts. If a hostile takeover situation should arise, shares of Preferred Stock could be issued to purchasers sympathetic with the Company's management or others in such a way as to render more difficult or to discourage a merger, tender offer, proxy contest, the assumption of control by a holder of a large block of the Company's securities or the removal of incumbent management.

The effects of the issuance of the Preferred Stock on the holders of Common Stock could include, among other things, (i) reduction of the amount otherwise available for payments of dividends on Common Stock if dividends are payable on the series of Preferred Stock; (ii) restrictions on dividends on Common Stock if dividends on the series of Preferred Stock are in arrears; (iii) dilution of the voting power of Common Stock if the series of Preferred Stock has voting rights, including a possible "veto" power if the series of Preferred Stock has class voting rights; (iv) dilution of the equity interest of holders of Common Stock if the series of Preferred Stock is convertible, and is converted, into Common Stock; and (v) restrictions on the rights of holders of Common Stock to share in the Company's assets upon liquidation until satisfaction of any liquidation preference granted to the holders of the series of Preferred Stock. Holders of Common Stock have no preemptive rights to purchase or otherwise acquire any Preferred Stock that may be issued.

COMMON STOCK

The holders of the Common Stock are entitled to one vote for each share of Common Stock owned. Except as expressly provided by law and except for any voting rights which may be conferred by the Board of Directors on any shares of Preferred Stock issued, all voting power is in the Common Stock. Holders of Common Stock may not cumulate their votes for the election of directors. Holders of Common Stock do not have preemptive rights to acquire any additional, unissued or treasury shares of the Company, or securities of the Company convertible into or carrying a right to subscribe for or acquire shares of the Company.

Holders of Common Stock will be entitled to receive dividends out of funds legally available therefor, if and when properly declared by the Board of Directors. See "Risk Factors -- Dividend History and Restrictions on Ability to Pay Dividends" and "Supervision and Regulation."

On the liquidation of the Company, the holders of Common Stock are entitled to share pro rata in any distribution of the assets of the Company, after the holders of shares of Preferred Stock have received the liquidation preference of their shares plus any cumulated but unpaid dividends (whether or not earned or declared), if any, and after all other indebtedness of the Company has been retired.

TEXAS LAW AND CERTAIN PROVISIONS OF THE ARTICLES OF INCORPORATION AND BYLAWS

Certain provisions of Texas law, the Company's Articles of Incorporation and the Company's Bylaws could make more difficult the acquisition of the Company by means of a tender offer, a proxy contest or otherwise and the removal of incumbent officers and directors. These provisions are intended to discourage certain types of coercive takeover practices and inadequate takeover bids and to encourage persons seeking to acquire control of the Company to negotiate first with the Company.

The Company is subject to the provisions of the Texas Business Combination Law (Articles 13.01 through 13.08 of the TBCA), which provides that a Texas corporation such as the Company may not engage in certain business combinations, including mergers, consolidations and asset sales, with a person, or an affiliate or associate of such person, who is an "Affiliated Shareholder" (generally defined as the holder of 20% or more of the corporation's voting shares) for a period of three years from the date such person became an Affiliated Shareholder unless: (i) the business combination or purchase or acquisition of shares made by the Affiliated Shareholder was approved by the board of directors of the corporation before the Affiliated Shareholder became an Affiliated Shareholder or (ii) the business combination was approved by the affirmative vote of the holders of at least two-thirds of the outstanding voting shares of the corporation not beneficially owned by the Affiliated Shareholder, at a meeting of shareholders called for that purpose (and not by written consent), not less than six months after the Affiliated Shareholder became an Affiliated Shareholder. The Texas Business Combination Law is not applicable to:
(i) the business combination of a

65

corporation: (a) where the corporation's original charter or bylaws contain a provision expressly electing not to be governed by the Texas Business Combination Law, (b) that adopted an amendment to its charter or bylaws before December 31, 1997, expressly electing not to be governed by the Texas Business Combination Law, or (c) that adopts an amendment to its charter or bylaws after December 31, 1997, by the affirmative vote of the holders, other than Affiliated Shareholders, of at least two-thirds of the outstanding voting shares of the corporation, expressly electing not to be governed by the Texas Business Combination Law; (ii) a business combination of a corporation with an Affiliated Shareholder that became an Affiliated Shareholder inadvertently, if the Affiliated Shareholder: (a) as soon as practicable divests itself of enough shares to no longer be an Affiliated Shareholder and (b) would not at any time within the three year period preceding the announcement of the business combination have been an Affiliated Shareholder but for the inadvertent acquisition; (iii) a business combination with an Affiliated Shareholder that was the beneficial owner of 20% or more of the outstanding voting shares of the corporation on December 31, 1996, and continuously until the announcement date of the business combination; (iv) a business combination with an Affiliated Shareholder who became an Affiliated Shareholder through a transfer of shares of the corporation by will or intestate succession and continuously was such an Affiliated Shareholder until the announcement date of the business combination; and (v) a business combination of a corporation with a wholly owned subsidiary if the subsidiary is not an affiliate or associate of the Affiliated Shareholder other than by reason of the Affiliated Shareholder's beneficial ownership of the voting shares of the corporation. Neither the Articles of Incorporation nor the Bylaws of the Company contain any provision expressly providing that the Company will not be subject to the Texas Business Combination Law. The Texas Business Combination Law may have the effect of inhibiting a non-negotiated merger or other business combination involving the Company, even if such event would be beneficial to the Company's shareholders.

The following discussion is a summary of certain material provisions of the Company's Articles of Incorporation and the Company's Bylaws, copies of which are filed as exhibits to the Registration Statement of which this Prospectus is a part.

CLASSIFIED BOARD OF DIRECTORS. Under the Company's Bylaws, the Board of Directors is classified into three classes, with the directors being elected for staggered, three-year terms. The classification of the Company's Board of Directors will have the effect of making it more difficult to change the composition of the Board of Directors, because at least two annual meetings of the shareholders would be required to change the control of the Board of Directors rather than one. In addition, the Bylaws provide that directors may be removed by the shareholders only for cause and that vacancies on the Board of Directors may be filled by the remaining directors.

ADVANCE NOTICE OF SHAREHOLDER PROPOSALS AND NOMINATIONS. The Company's Bylaws establish an advance notice procedure for shareholders to make nominations of candidates for election as directors or bring other business before any meeting of shareholders of the Company (the "Shareholder Notice Procedure"). The Shareholder Notice Procedure provides that only persons who are nominated by, or at the direction of, the Board, or by a shareholder who has given timely written notice to the Secretary of the Company prior to the meeting at which directors are to be elected, will be eligible for election as directors of the Company and that, at a shareholders' meeting, only such business may be conducted as has been brought before the meeting by, or at the direction of, the Board of Directors or by a shareholder who has given timely written notice to the Secretary of the Company of such shareholder's intention to bring such business before such meeting.

Under the Shareholder Notice Procedure, for notice of shareholder nominations or other business to be made at a shareholders' meeting to be timely, such notice must be received by the Company not less than 60 days prior to the meeting.

A shareholder's notice to the Company proposing to nominate a person for election as a director or proposing other business must contain certain information specified in the Bylaws, including the identity and address of the nominating shareholder, a representation that the shareholder is a record holder of stock of the Company entitled to vote at the meeting and information regarding each proposed nominee or each

66

proposed matter of business that would be required under the federal securities laws to be included in a proxy statement soliciting proxies for the proposed nominee or the proposed matter of business.

The Shareholder Notice Procedure may have the effect of precluding a contest for the election of directors or the consideration of shareholder proposals if the proper procedures are not followed, and of discouraging or deterring a third party from conducting a solicitation of proxies to elect its own slate of directors or to approve its own proposal, without regard to whether consideration of such nominees or proposals might be harmful or beneficial to the Company and its shareholders.

SPECIAL MEETINGS OF SHAREHOLDERS. The Articles of Incorporation provide that special meetings of shareholders can be called by shareholders only at the request of the holders of not less than one-half of the outstanding shares of stock entitled to vote at the meeting.

REDUCED SHAREHOLDER VOTE REQUIRED FOR CERTAIN ACTIONS. The Company's Articles of Incorporation provide that, notwithstanding any provision of the TBCA that would require approval of more than a majority of the shares entitled to vote on such matter and present or represented by proxy at the meeting, the vote or approval of a majority of the shares of the Company's stock entitled to vote on such matter will be sufficient to approve such matter. This provision reduces the required shareholder approval level for certain actions such as a merger, a consolidation, a share exchange, certain sales of substantially all of the Company's assets, a dissolution or an amendment to the Company's Articles of Incorporation, each of which would otherwise require two-thirds shareholder approval under Texas law.

NO ACTION BY WRITTEN CONSENT WITHOUT UNANIMOUS WRITTEN CONSENT. Under the TBCA, no action required or permitted to be taken at an annual or special meeting of shareholders may be taken by written consent in lieu of a meeting of shareholders without the unanimous written consent of all shareholders unless the articles of incorporation specifically allow action by less than unanimous consent. The Company's Articles of Incorporation do not contain such a provision.

AMENDMENT OF BYLAWS. The Company's Bylaws provide that the Bylaws may be amended only by the Board of Directors. Shareholders do not have the power to amend the Company Bylaws.

67

UNDERWRITING

Subject to the terms and conditions of the Purchase Agreement among the Company, the Selling Shareholders and the Representatives on behalf of the Underwriters, the Underwriters have agreed severally to purchase from the Company and the Selling Shareholders the following respective number of shares of Common Stock at the initial public offering price less the underwriting discounts and commissions set forth on the cover page of this Prospectus.

                NAME                    NO. OF SHARES
-------------------------------------   --------------
Keefe, Bruyette & Woods, Inc.........
Hoefer & Arnett, Incorporated........

                                        --------------
     Total...........................
                                        ==============

The Purchase Agreement provides that the obligations of the Underwriters are subject to certain conditions precedent and that the Underwriters will purchase all such shares of the Common Stock if any of such shares are purchased. The Underwriters are obligated to take and pay for all of the shares of Common Stock offered hereby (other than those covered by the over-allotment option described below) if any are taken.

The Company has been advised by the Representatives that the Underwriters propose to offer to such shares of Common Stock to the public at the public offering price set forth on the cover page of this Prospectus and to certain dealers at such price less a concession not in excess of $ per share. The Underwriters may allow, and such dealers may re-allow, a concession not in excess of $ per share to certain other dealers. After the initial public offering, the offering price and other selling terms may be changed by the Underwriters.

Pursuant to the Purchase Agreement, the Company has granted to the Underwriters an option, exercisable not later than 30 days after the date of this Prospectus, to purchase up to 251,667 additional shares of Common Stock at the public offering price, less the underwriting discounts and commissions set forth on the cover page of this Prospectus, solely to cover over-allotments. To the extent that the Underwriters exercise such option, the Underwriters will become obligated, subject to certain conditions, to purchase approximately the same percentage of such additional shares as the number set forth next to such Underwriter's name in the preceding table bears to the total number of shares in such table, and the Company will be obligated, pursuant to the option, to sell such shares to the Underwriters.

The Company, each of its directors and executive officers, each of the Selling Shareholders and certain other shareholders of the Company have agreed not to sell or otherwise dispose of any shares of Common Stock for a period of 180 days after the date of this Prospectus without the prior written consent of the Representatives. See "Risk Factors -- Shares Eligible for Future Sale."

The Company and the Selling Shareholders have agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act.

Until the distribution of the Common Stock is completed, rules of the Commission (as defined herein) may limit the ability of the Underwriters and certain selling group members to bid for and purchase the Common Stock. As an exception to these rules, the Underwriters are permitted to engage in certain transactions that stabilize the price of the Common Stock. Such transactions consist of bids or purchases for the purpose of pegging, fixing or maintaining the price of the Common Stock.

If the Underwriters create a short position in the Common Stock in connection with the Offering, i.e., if they sell a greater aggregate number of shares of Common Stock than is set forth on the cover page of this Prospectus, the Underwriters may reduce the short position by purchasing shares of Common Stock in the

68

open market. The Underwriters may also elect to reduce any short position by exercising all or part of the over-allotment option described above.

The Underwriters may also impose a penalty bid on certain selling group members. This means that if the Underwriters purchase Common Stock in the open market to reduce the selling group members' short position or to stabilize the price of the Common Stock, they may reclaim the amount of the selling concession from the selling group members who sold those shares of Common Stock as part of the Offering.

In general, purchases of a security for the purpose of stabilization or to reduce a short position could cause the price of the security to be higher than it might be in the absence of such purchases. The imposition of a penalty bid might also have an effect on the price of a security to the extent that it were to discourage resales of the security.

Neither the Company nor the Representatives make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Common Stock. In addition, neither the Company nor the Representatives make any representation that the Underwriters will engage in such transactions or that such transactions, once commenced, will not be discontinued without notice.

The Underwriters and dealers may engage in passive market making transactions in the shares of Common Stock in accordance with Rule 103 of Regulation M promulgated by the Commission. In general, a passive market maker may not bid for, or purchase, shares of Common Stock at a price that exceeds the highest independent bid. In addition, the net daily purchases made by any passive market maker generally may not exceed 30% of its average daily trading volume in the Common Stock during a specified two month prior period, or 200 shares, whichever is greater. A passive market maker must identify passive market making bids as such on the Nasdaq electronic inter-dealer reporting system. Passive market making may stabilize or maintain the market price of the Common Stock above independent market levels. Underwriters and dealers are not required to engage in passive market making and may end passive market making activities at any time.

Prior to the Offering, there has been no public market for the Common Stock. Consequently, the initial public offering price for the Common Stock has been determined by negotiations between the Company and the Representatives. Among the factors considered in such negotiations were prevailing market and general economic conditions, the market capitalizations, trading histories and stages of development of other traded companies that the Company and the Representatives believed to be comparable to the Company, the results of operations of the Company in recent periods, the current financial position of the Company, estimates of the business potential of the Company and the present state of the Company's development and the availability for sale in the market of a significant number of shares of Common Stock. Additionally, consideration has been given to the general status of the securities market, the market conditions for new issues of securities and the demand for securities of comparable companies at the time the Offering was made.

Application has been made for quotation of the Common Stock on the Nasdaq/National Market.

LEGAL MATTERS

The validity of the shares of Common Stock to be issued by the Company will be passed upon by Bracewell & Patterson, L.L.P., Houston, Texas. Certain legal matters with respect to the Common Stock offered hereby will be passed upon for the Underwriters by Skadden, Arps, Slate, Meagher & Flom LLP, New York, New York.

INDEPENDENT AUDITORS' REPORT

To the Shareholders and Board of Directors of Prosperity Bancshares, Inc. and Subsidiaries:

We have audited the accompanying consolidated balance sheets of Prosperity Bancshares, Inc. and subsidiaries (collectively, the "Company") as of December 31, 1997 and 1996, and the related consolidated statements of income, shareholders' equity and cash flows for each of the three years in the period ended December 31, 1997. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing standards. 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 as of December 31, 1997 and 1996, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 1997 in conformity with generally accepted accounting principles.

PROSPERITY BANCSHARES, INC. AND SUBSIDIARY

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, Inc. ("Holdings") and First Prosperity Bank (the "Bank") (collectively referred to as the "Company") provide retail and commercial banking services.

The Bank operates eleven branch banking offices in South Central Texas, with three locations in Houston and eight locations south, southeast and southwest of Houston in Angleton, Bay City, Cuero, Edna, El Campo, West Columbia and Victoria.

PRINCIPLES OF CONSOLIDATION -- The consolidated financial statements include the accounts of Bancshares and its wholly owned subsidiaries. All significant intercompany transactions have been eliminated in consolidation. The accounting and reporting policies of the Company conform to generally accepted accounting principles ("GAAP") and the prevailing practices within the banking industry. A summary of significant accounting and reporting policies is as follows:

INTERIM FINANCIAL INFORMATION -- Financial information as of June 30, 1998 and for the six months ended June 30, 1998 and 1997 is unaudited. Such information includes all adjustments (consisting of only normal recurring adjustments), that are necessary in the opinion of management, for a fair statement of the financial information in the interim periods. The results from operations for the periods ended June 30, 1998 is not necessarily indicative of the results for the full fiscal year.

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 those estimates.

SECURITIES -- Investment 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 investments until their estimated maturities. Under certain circumstances (including the deterioration of the issuer's creditworthiness or a change in tax law or statutory or regulatory requirements), securities may be sold or transferred to another portfolio.

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 -- 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 "sum of the digits" method which records interest in proportion to the declining outstanding balances of the loans; for single payment loans, such income is recognized using the straight-line method.

PROSPERITY BANCSHARES, INC. AND SUBSIDIARY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Effective January 1, 1995, the Company adopted 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." SFAS No. 114 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. Prior to the adoption of SFAS No. 114, the Company's methodology for determining the adequacy of the allowance for credit losses did not incorporate the concept of the time value of money and the expected future interest cash flow.

As permitted by SFAS No. 118, interest revenue received on impaired loans continues to be either applied against principal or realized as interest revenue, according to management's judgment as to the collectibility of principal. Adoption of these pronouncements, SFAS Nos. 114 and 118, had no impact on the Company's consolidated financial statements including the level of the allowance for credit losses.

OTHER REAL ESTATE -- Real estate properties acquired through, or in lieu of, loan foreclosure are to be sold and are initially recorded at the lesser of the outstanding loan balance or the fair value at the date of foreclosure establishing a new cost basis. After foreclosure, valuations are periodically performed by management and the real estate is carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in the net gain/loss and carrying costs of other real estate.

NONREFUNDABLE FEES AND COSTS ASSOCIATED WITH LENDING ACTIVITIES -- Loan origination fees are recognized over the life of the related loan as an adjustment to yield using the interest method.

Generally, loan commitment fees 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 LOANS 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. Generally, 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

F-9

PROSPERITY BANCSHARES, INC. AND SUBSIDIARY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

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 in the existing 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.

Management's judgment as to the level of losses on existing loans involves the consideration of current and anticipated economic conditions and their potential effects on specific borrowers; an evaluation of the existing relationships among loans, probable credit losses and the present level of the allowance; results of examinations of the loan portfolio by regulatory agencies; and management's internal review of the loan portfolio. In determining the collectibility of certain loans, management also considers the fair value of any underlying collateral. The amounts ultimately realized may differ from the carrying value of these assets because of economic, operating or other conditions beyond the Company's control.

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.

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 thirty years.

AMORTIZATION OF GOODWILL -- Goodwill is amortized using the straight-line method over a period of 15 to 25 years. Goodwill is periodically assessed for impairment.

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 bases.

Realization of net deferred tax assets is dependent on generating sufficient future taxable income. Although realization is not assured, management believes it is more likely than not that all of the net deferred tax assets will be realized. The amount of the net deferred tax asset considered realizable, however, could be reduced in the short term if estimates of future taxable income are reduced.

STOCK-BASED COMPENSATION -- The Company accounts for its employee stock options using the intrinsic value-based method and makes pro forma disclosures of net income and earnings per share using the fair value-based method (see Note 14).

STATEMENTS OF CASH FLOWS -- 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.

RECLASSIFICATIONS -- Certain reclassifications have been made to 1997, 1996 and 1995 balances to conform to the current year presentation. All reclassifications have been applied consistently for the periods presented.

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

F-10

PROSPERITY BANCSHARES, INC. AND SUBSIDIARY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

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 following table illustrates the computation of basic and diluted earnings per share after effect of stock split (Note 22):

RECENTLY ISSUED ACCOUNTING STANDARDS -- Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging Activities" establishes accounting and reporting standards for derivative instruments and requires that an entity recognize all derivatives as either assets or liabilities in the balance sheet and measure those instruments at fair value. This statement is effective for periods beginning after June 15, 1999. Management believes the implementation of this pronouncement will not have a material effect on the Company's financial statements.

SFAS No. 131, "Disclosures about Segments of an Enterprise and Related Information" establishes new standards for public companies to report information about their operating segments, products and services, geographic areas and major customers. The statement is effective for financial statements issued for periods beginning after December 15, 1997. Management has not yet determined what its reporting segments will be under SFAS No. 131.

2. ACQUISITION OF BRANCHES

ANGLETON BRANCH -- During March 1997, the Company entered into a purchase and assumption agreement with another bank to purchase certain assets and to assume certain deposit accounts and related accrued interest payable of a branch located in Angleton, Texas. Effective June 20, 1997, the Company purchased approximately $723,000 in real property and fixed assets and assumed deposits, including unpaid accrued interest, totaling approximately $29,370,000.

In connection with the purchase, the Company paid a cash premium of approximately $1,990,000. This premium was recorded as goodwill and will be amortized on a straight-line basis over 15 years. The acquisition was partially financed with proceeds from the common stock issuance (see Note 17).

PROSPERITY BANCSHARES, INC. AND SUBSIDIARY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

As discussed in Note 1, the Bank adopted SFAS No. 114 and 118 effective January 1, 1995. Adoption of these statements had no impact on the Company's financial statements including the level of the allowance for credit losses. Instead, it resulted only in a reallocation of the existing allowance for credit losses.

At June 30, 1998 (unaudited) and December 31, 1997 and 1996, there was no recorded investment in impaired loans under SFAS No. 114, "Accounting by Creditors for Impairment of a Loan." At December 31, 1995, the recorded investment in impaired loans under SFAS No. 114 was approximately $23,000 and required an allowance for credit losses of approximately $5,000. The average recorded investment in impaired loans for the year ended December 31, 1995 was approximately $19,000. The Company recognized interest revenue on these impaired loans of approximately $3,000 in 1995.

As of June 30, 1998 (unaudited) and December 31, 1997 and 1996, loans outstanding to directors, officers and their affiliates were approximately $3,036,000, $2,432,000 and $3,210,000, respectively. In the opinion of management, all transactions entered into between the Company and such related parties have been, and are, in the ordinary course of business, made on the same terms and conditions as similar transactions with unaffiliated persons.

An analysis of activity with respect to these related-party loans is as follows:

Interest expense for certificates of deposit in excess of $100,000 was approximately $593,000, $1,264,000, $1,291,000, and $1,247,000 for the periods ended June 30, 1998 (unaudited), December 31, 1997, 1996, and 1995, respectively.

The Company has no brokered deposits and there are no major concentrations of deposits.

10. NOTE PAYABLE AND OTHER BORROWINGS

NOTE PAYABLE -- During December 1997, Bancshares entered into an agreement with a bank to borrow up to $8,000,000 under a reducing, revolving line of credit (the "Line"). The purpose of the Line is to provide funding for potential acquisitions in the future. The maximum amount available under the Line is reduced by $1,142,857 each year beginning December 1998 with all amounts due and payable on December 31, 2004. The Line bears interest, payable quarterly, at the Federal Funds Rate plus 2.75%. The Line is collateralized by 100% of the issued and outstanding common shares of Holdings and the Bank. At June 30, 1998 (unaudited) and December 31, 1997, Bancshares had no outstanding borrowings under the Line. During 1997, Bancshares paid off the outstanding balance under a similar agreement (the "Old Line") with a bank. At December 31, 1996, borrowings under the Old Line totaled $3,266,666.

OTHER BORROWINGS -- At December 31, 1997, Federal Home Loan Bank ("FHLB") advances totaled $2,800,000 with a floating interest rate of 6.9%. There were no advances at June 30, 1998 (unaudited) or

F-16

PROSPERITY BANCSHARES, INC. AND SUBSIDIARY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

December 31, 1996. The FHLB line of credit agreement matures May 14, 1999. The advances under the FHLB line of credit are secured by a blanket pledge of the Bank's one-to-four family mortgages.

11. 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.

12. 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 and to reduce its own exposure to fluctuations in interest rates. These financial instruments include commitments to extend credit and standby letters of credit. These instruments 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.

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 those 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 various financial instruments entered into by the Company:

                                                                DECEMBER 31,
                                          JUNE 30,     ------------------------------

                                        ------------   --------------  --------------
                                        (UNAUDITED)
Financial instruments whose contract
  amounts represent credit risk:
     Commitments to extend credit....   $ 10,348,000   $   11,856,158  $   11,660,000
     Standby letters of credit.......        279,000          315,200          45,000

At June 30, 1998 (unaudited), approximately $3,900,000 of commitments to extend credit have fixed rates ranging from 6.60% to 11.50%. 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 requirements.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

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. STOCK INCENTIVE PROGRAM

During 1995 the Company's Board of Directors approved a stock option plan (the "Plan") for executive officers and key employees to purchase common stock of Bancshares. On May 31, 1995, the Company granted 260,000 options, after stock split, (see Note 22) which vest over a ten-year period beginning on the date of grant. Fifty percent of the options vest after the five year period and ten percent vest in each year thereafter. The options may not be exercised until the optionee has completed five years of employment after the date of grant. The options were granted at an average exercise price of $4.40 (after stock split). Compensation expense was not recognized for the stock options because the options had an

There were no options granted, exercised, forfeited, or expired during 1997 and 1996. At June 30, 1998 (unaudited) and December 31, 1997 and 1996, there were no options that were exercisable under the Plan. On February 10, 1998, the Company granted 60,000 options under the Plan. The options were granted at an exercise price of $6.25. Compensation expense was not recorded for the stock options because the exercise price approximated the fair value of common stock at the date of grant.

The weighted-average grant date fair value of the stock options granted in 1995 was $.39. The weighted-average remaining contractual life of options outstanding at December 31, 1997 was 7.42 years. The fair value of each stock option was estimated using an option-pricing model with the following assumptions used: risk-free interest rate of 6.49%; dividend yield of 4.54%; and an expected life of 6.5 years.

If compensation expense had been recorded based on the fair value at the grant date for awards consistent with SFAS No. 123, the Company's net income would have been $2,052,660, $3,555,480, $2,704,040 and $2,317,522 and earnings per share would have been $.53, $.94, $.77 and $.66 for the six months ended June 30, 1998 (unaudited) and the years ended December 31, 1997, 1996 and 1995, respectively.

15. PROFIT SHARING PLAN

The Company has adopted a profit sharing plan pursuant to Section 401(k) of the Internal Revenue Code whereby participants may contribute up to 15% of their compensation. Matching contributions are made at the discretion of the Company. Such matching contributions were approximately $48,000, $38,000, $87,000, $72,000 and $56,000 for the six months ended June 30, 1998 (unaudited) and 1997 (unaudited) and the years ended December 31, 1997, 1996, and 1995, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

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 $191,000 for the year ended December 31, 1997 and $180,000 for the years ended December 31, 1996 and 1995.

LITIGATION -- Various lawsuits are pending against the Company. Management, after reviewing these lawsuits with outside counsel, considers that the aggregate liabilities, if any, will not be material to the consolidated financial statements.

17. SHAREHOLDERS' EQUITY

During 1997, the Company sold 480,000 shares of common stock at $6.25 per share, after stock split, (see Note 22), which approximated the book value of the Company at the time of the sale. Proceeds to the Company totaling $3,000,000 were used to fund the acquisition of a branch (see Note 2) and to repay borrowings under a line of credit arrangement with a bank (Note 10).

Dividends paid by Bancshares and the Bank are subject to restrictions by certain regulatory agencies. There was an aggregate of approximately $7,300,000 and $4,835,000 available for payment of dividends by Bancshares and by the Bank to Bancshares, respectively, at December 31, 1997 under these restrictions. Dividends paid by Bancshares during the years ended December 31, 1997 and 1996 were $574,536 and $351,388, respectively. Dividends paid by the Bank to Bancshares during the years ended December 31, 1997 and 1996 were $2,922,150 and $661,000, respectively.

18. 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 judgments 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. Management believes, as of June 30, 1998 and December 31, 1997, that the Company and the Bank met all capital adequacy requirements to which they are subject.

At December 31, 1997, the most recent notification from the State of Texas Department of Banking 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.

19. DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INFORMATION

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.

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.

LOAN RECEIVABLES -- 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.

DEPOSIT LIABILITIES -- 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.

LONG-TERM DEBT AND 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.

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 estimated fair values of the Company's financial instruments are as follows (in thousands):

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

The differences in fair value and carrying value of commitments to extend credit and standby letters of credit were not material at December 31, 1997 and 1996.

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.

20. COMPREHENSIVE INCOME

SFAS No. 130, "Reporting Comprehensive Income" requires that all components of comprehensive income and total comprehensive income be reported on one of the following: (1) the statement of income, (2) the statement of stockholders' equity, or (3) a separate statement of comprehensive income. Comprehensive income is comprised of net income and all changes to stockholders' equity, except those due to investments by owners (changes in paid-in capital) and distributions to owners (dividends). The Company adopted this statement effective January 1, 1998 and has elected to report comprehensive income in the consolidated statements of stockholders' equity.

Other comprehensive income consists of unrealized gains and losses on available for sale securities. For the six months ended June 30, 1998, the change in net unrealized loss on available for sale securities is reported in the consolidated statement of stockholders' equity.

22. PENDING ACQUISITION

During November 1997, the Company entered into a purchase and assumption agreement with another bank to purchase certain assets and to assume certain deposit accounts and related accrued interest payable of a branch located in West Columbia, Texas. This transaction, which has met regulatory approval, is expected to be completed on or about February 27, 1998. At that time, the Company expects to purchase loans totaling approximately $120,000 and assume deposit liabilities of approximately $7,500,000. The Company expects to pay a cash premium totaling approximately $250,000 for the transaction.

23. SUBSEQUENT EVENTS

On September 10, 1998, the Company effected a four for one common stock split in the form of a common stock dividend (the "Stock Split"). All share and per share information for common stock has been restated to reflect the Stock Split. In September 1998, the Company increased the number of authorized shares of common stock from 1,000,000 to 50,000,000 and authorized 20,000,000 shares of preferred stock with a par value of $1.

In June 1998, the Company entered into a merger agreement with a bank located in East Bernard, Texas. This transaction, which has met regulatory approval, is expected to be completed on or about October 1, 1998.

On February 10, 1998, the Company granted 60,000 options under the 1995 stock option plan. The options were granted at an exercise price of $6.25. Compensation expense was not recorded for the stock options because the exercise price approximated the fair value of common stock at the date of the grant.

In 1998, the Company approved a new stock option plan which authorizes the issuance of up to 460,000 shares of common stock.

INDEPENDENT AUDITOR'S REPORT

To the Board of Directors
Union State Bank
East Bernard, Texas

We have audited the accompanying statements of condition of Union State Bank as of December 31, 1997 and 1996, and the related statements of income, changes in shareholders' equity and cash flows for the years then ended. 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 generally accepted auditing standards. 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, the financial statements referred to above present fairly, in all material respects, the financial position of Union State Bank at December 31, 1997 and 1996, and the results of its operations and its cash flows for the years then ended in conformity with generally accepted accounting principles.

UNION STATE BANK
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 1997 AND 1996

NOTE A SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES

The accounting and reporting policies of Union State Bank are in accordance with generally accepted accounting principles and the prevailing practices within the banking industry. A summary of significant accounting policies is as follows:

ESTIMATES -- The preparation of financial statements in conformity with generally accepted accounting principles 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 those estimates.

Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for possible credit losses on loans, the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans and in the determination of investment security estimated market values. In connection with the determination of the allowances for possible losses on loans and foreclosed real estate, management obtains independent appraisals for significant properties. The estimated market value of investment securities is determined by a third party investment company.

While management uses available information to recognize losses on loans and foreclosed real estate, further reductions in the carrying amounts of loans and foreclosed assets may be necessary based on changes in local economic conditions. In addition, regulatory agencies, as an integral part of their examination process, periodically review the estimated losses on loans and foreclosed real estate. Such agencies may require the Bank to recognize additional losses based on their judgments about information available to them at the time of their examination. Because of these factors, it is reasonably possible that the estimated losses on loans and foreclosed real estates may change materially in the near term. However, the amount of the change that is reasonably possible cannot be estimated.

INTERIM FINANCIAL INFORMATION -- Financial information as of and for the six months ended June 30, 1998 and 1997 is unaudited. Such information includes all adjustments (consisting of only normal recurring adjustments), that are necessary in the opinion of management, for a fair statement of the financial information in the interim periods. The results from operations for the periods ended June 30, 1998 is not necessarily indicative of the results for the full fiscal year.

TRADING SECURITIES -- Securities that are held for short-term resale are classified as trading account securities and recorded at their fair values. Realized and unrealized gains and losses on trading account securities are included in other income. At December 31, 1997 and 1996, the Bank did not classify any of its securities as trading securities.

SECURITIES HELD TO MATURITY -- Government, Federal agency, and corporate debt securities that management has the positive intent and ability to hold to maturity are reported at cost, adjusted for amortization of premiums and the accretion of discounts that are recognized in interest income using methods approximating the interest method over the period to maturity. Mortgage backed securities represent participating interests in pools of long-term first mortgage loans originated and serviced by issuers of the securities. Mortgage backed securities are carried at unpaid principal balances, adjusted for unamortized premiums and unearned discounts. Premiums and discounts are amortized using methods approximating the interest method over the remaining period to contractual maturity, adjusted for anticipated prepayments.

SECURITIES AVAILABLE FOR SALE -- Available for sale securities consist of investment securities not classified as trading securities nor as held to maturity securities. Unrealized holding gains and losses, net of tax, on available for sale securities are reported as a net amount in a separate component of shareholders'

F-36

UNION STATE BANK
NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

equity until realized. Gains and losses on the sale of available for sale securities are determined using the specific identification method. The amortization of premiums and the accretion of discounts are recognized in interest income using methods approximating the interest method over the period of maturity.

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

CONCENTRATIONS OF CREDIT -- Substantially all of the Bank's loans, commitments and letters of credit have been granted to customers in the Bank's market area. Generally, such customers are depositors of the Bank. The concentrations of credit by type of loan are set forth in Note C. It is the Bank's policy to not extend credit to any single borrower or group of related borrowers in excess of the Bank's legal lending limit.

INTEREST RATE RISK -- The Bank is principally engaged in providing short-term commercial loans with interest rates that fluctuate with various market indices and intermediate-term, fixed rate real estate loans. These loans are primarily funded through short-term demand deposits and longer-term certificates of deposit with fixed rates.

LOANS -- Loans are stated at the principal amount outstanding, net of unearned discount. Unearned discount relates principally to consumer installment loans. The related interest income for multi-payment loans is recognized as interest in proportion to the declining outstanding balances of the loans; for single payment loans such income is recognized under the straight-line method. Both methods approximate the interest method.

NON-PERFORMING LOANS AND PAST DUE LOANS -- Included in the non-performing 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 or identified as impaired, interest accrued and uncollected during the current year prior to the judgment of uncollectibility, is charged to operations. Interest accrued during prior periods is charged to allowance for possible credit losses. Generally, 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.

Renegotiated 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 POSSIBLE CREDIT LOSSES -- The allowance for possible credit losses is a valuation allowance available for losses incurred on loans and other commitments to extend credit. All losses are charged to the allowance for possible credit losses when the loss actually occurs or when a determination is made that a loss is likely to occur. Recoveries are credited to the allowance at the time of recovery.

Throughout the year, management estimates the likely level of losses to determine whether the allowance for possible credit losses is adequate to absorb anticipated losses in the existing portfolio. Based on these estimates, an amount is charged to the provision for possible credit losses and credited to the

F-37

UNION STATE BANK
NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

allowance for possible credit losses in order to adjust the allowance to a level determined to be adequate to absorb losses.

Management's judgment as to the level of losses on existing loans involves the consideration of current and anticipated economic conditions and their potential effects on specific borrowers; an evaluation of the existing relationships among loans, potential loan losses, and the present level of the allowance; results of examinations of the loan portfolio by regulatory agencies; results of examinations of the loan portfolio by an external consultant; and management's internal review of the loan portfolio. In determining the collectibility of certain loans, management also considers the fair value of any underlying collateral. The amounts ultimately realized may differ from the carrying value of these assets because of economic, operating or other conditions beyond the Bank's control.

It should be understood that estimates of credit losses involve judgment. While it is possible that in particular periods the Bank may sustain losses which are substantial relative to the allowance for credit losses, it is the judgment of management that the allowances for credit losses reflected in the statements of condition are adequate to absorb losses which may exist in the current loan portfolio.

BANK PREMISES AND EQUIPMENT -- Bank Premises and equipment are carried at cost less accumulated depreciation and amortization. Depreciation expense is computed principally on a tax method which approximates the straight-line method over the estimated useful lives of the assets.

REAL ESTATE ACQUIRED BY FORECLOSURE -- Real estate acquired by foreclosure is recorded at the fair value of the property less any selling costs, as applicable, at the time of foreclosure. Subsequent to foreclosure, real estate is carried at the lower of its new cost basis or fair value, less estimated costs to sell. Any adjustments to reflect declines in value below the recorded amounts are recognized and are charged to income in the period such determination is assessed. Required developmental costs associated with foreclosed property under construction are capitalized and considered in determining the fair value of the property.

Operating expenses of such properties, net of related income, and gains and losses on their disposition are included in other non-interest expense.

INCOME TAXES -- Under SFAS No. 109, the Bank uses the balance sheet approach for recording deferred taxes. The balance sheet approach accounts for deferred income taxes by applying statutory tax rates in effect at the balance sheet date to differences between the book basis and the tax basis of assets and liabilities. The resulting deferred tax assets and liabilities are adjusted to reflect changes in tax law or rates.

STATEMENTS OF CASH FLOWS -- For purposes of reporting cash flows, cash and cash equivalents include cash and due from banks and federal funds sold. Generally, federal funds are sold for one-day periods.

NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

In the ordinary course of business, the Bank has and expects to continue to have transactions, including borrowings, with its officers, directors, principal stockholders, and their affiliates. In the opinion of management, such transactions were on substantially the same terms, including interest rates and collateral, as those prevailing at the time of comparable transactions with other persons and did not involve more than a normal risk of collectibility or present any other unfavorable features to the Bank. Loans to such borrowers are summarized as follows:

                                       ============  ============

Interest expense for certificates of deposit in excess of $100,000 amounted to approximately $476,281 and $477,270 for the years ended December 31, 1997 and 1996, respectively. The bank has no brokered deposits and there are no major concentrations of deposits.

NOTE J FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK

The Bank is party to various financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the statements of condition. The contract or notional amounts of those instruments reflect the extent of the involvement the Bank has in particular classes of financial instruments. The Bank'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 those instruments. The Bank 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 various financial instruments whose contract amounts represent credit risk:

                                              1997          1996
                                          ------------  ------------
Commitments to extend credit............  $  7,792,741  $  6,416,767
Standby letters of credit...............  $     16,800  $     67,700

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 requirements.

The Bank evaluates each customer's credit worthiness on a case-by-case basis. The amount of collateral obtained, if considered necessary by the Bank upon extension of credit, is based on management's credit evaluation of the customer.

Standby letters of credit are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to its customers.

NOTE K EMPLOYEE BENEFITS

The Bank has a defined contribution savings plan in effect for substantially all full-time employees. An employee must contribute at least four percent of base pay to participate, which is then matched by the Bank. The Board of Directors may also make discretionary contributions each year. Benefit expenses amounted to $27,413 and $28,519 in 1997 and 1996, respectively.

                                          ==========  ==========

The provision for federal income taxes differs from the amount computed by applying the federal income tax statutory rate on earnings as follows:

                                              1997         1996

                                          ============  ==========

Deferred income taxes result primarily from temporary differences relating to the loan loss reserve and the recognition of unrealized investment losses on securities available for sale.

NOTE M STATEMENTS OF CASH FLOWS

Interest payments of $2,484,413 and $2,531,832 were made during 1997 and 1996, respectively. Federal income tax payments of $406,708 and $358,769 were made during 1997 and 1996, respectively.

NOTE N REGULATORY MATTERS

The Bank is subject to various regulatory capital requirements. Failure to meet the minimum regulatory capital requirements can initiate certain mandatory, and possible additional discretionary actions by regulators, that if undertaken, could have a direct material affect on the Bank's financial statements. Under the regulatory capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines involving quantitative measures of the Bank's assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Bank's capital amounts and classification under the prompt corrective action guidelines are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios of total risk-based capital and Tier I capital to risk-weighted assets (as defined in the regulations), and Tier I capital to adjusted total assets (as defined). Management believes, as of December 31, 1997 and 1996, that the Bank meets all the capital adequacy requirements to which it is subject.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

The Registrant's Articles of Incorporation and Bylaws require the Registrant to indemnify officers and directors of the Registrant to the fullest extent permitted by Article 2.02-1 of the Business Corporation Act of the State of Texas (the "TBCA"). The Articles of Incorporation and Bylaws of the Registrant are filed as Exhibit 3.1 and 3.2 to the Registration Statement. Generally, Article 2.02-1 of the TBCA permits a corporation to indemnify a person who was, is, or is threatened to be made a named defendant or respondent in a proceeding because the person was or is a director or officer if it is determined that such person (i) conducted himself in good faith, (ii) reasonably believed (a) in the case of conduct in his official capacity as a director or officer of the corporation, that his conduct was in the corporation's best interests, and/or (b) in other cases, that his conduct was at least not opposed to the corporation's best interests, and (iii) in the case of any criminal proceeding, had no reasonable cause to believe that his conduct was unlawful. In addition, the TBCA requires a corporation to indemnify a director or officer for any action that such director or officer is wholly successfully in defending on the merits.

The Registrant's Articles of Incorporation provide that a director of the Registrant will not be liable to the corporation for monetary damages for an act or omission in the director's capacity as a director, except to the extent not permitted by law. Texas law does not permit exculpation of liability in the case of (i) a breach of the director's duty of loyalty to the corporation or its shareholders, (ii) an act or omission not in good faith that involves intentional misconduct or a knowing violation of the law, (iii) a transaction from which a director received an improper benefit, whether or not the benefit resulted from an action taken within the scope of the director's office, (iv) an act or omission for which the liability of the director is expressly provided by statute, or (v) an act related to an unlawful stock repurchase or dividend.

Pursuant to the Purchase Agreement, a form of which is filed as Exhibit 1.1 to this Registration Statement, the Underwriters have agreed to indemnify the directors, officers and controlling persons of the Registrant against certain civil liabilities that may be incurred in connection with this Offering, including certain liabilities under the Securities Act.

The Registrant may provide liability insurance for each director and officer for certain losses arising from claims or changes made against them while acting in their capabilities as directors or officers of Registrant, whether or not Registrant would have the power to indemnify such person against such liability, as permitted by law.

(B) FINANCIAL STATEMENT SCHEDULES

None.

All other schedules for which provision is made in Regulation S-X of the Commission are not required under the related instructions or are inapplicable and, therefore, have been omitted.

ITEM 17. UNDERTAKINGS

(a) The undersigned Registrant hereby undertakes to provide the Underwriters at the closing specified in the underwriting agreement certificates in such denominations and registered in such names as required by the Underwriters to permit prompt delivery to each purchaser.

(b) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer, or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling

II-2


person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(c) The undersigned Registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this Registration Statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

The aggregate number of all classes of stock which the Corporation has authority to issue is 70,000,000 shares divided into (A) one class of 50,000,000 shares of Common Stock with a par value of $1.00 per share, and (B) one class of 20,000,000 shares of Preferred Stock with a par value of $1.00 per share, which may be divided into and issued in series as set forth in this Article Four.

Section 4.2 AUTHORIZATION OF DIRECTORS TO DETERMINE CERTAIN RIGHTS OF PREFERRED STOCK. The shares of Preferred Stock may be divided into and issued in series. The Board of Directors shall have the authority to establish series of unissued shares of Preferred Stock by fixing and determining the relative rights and preferences of the shares of any series so established, and to increase or decrease the number of shares within each such series; provided, however, that the Board of Directors may not decrease the number of shares within a series of Preferred Stock to less than the number of shares within such series that are then issued. The Preferred Stock of each such series shall have such designations, preferences, limitations, or relative rights, including voting rights, as shall be set forth in the resolution or resolutions establishing such series adopted by the Board of Directors, including, but without limiting the generality of the foregoing, the following:

(A) The distinctive designation of, and the number of shares of Preferred Stock that shall constitute, such series, which number (except where otherwise provided by the Board of Directors in the resolution establishing such series) may be increased or decreased


(but not below the number of shares of such series then outstanding) from time to time by like action of the Board of Directors;

(B) The rights in respect of dividends, if any, of such series of Preferred Stock, the extent of the preference or relation, if any, of such dividends to the dividends payable on any other class or classes or any other series of the same or other class or classes of capital stock of the Corporation and whether such dividends shall be cumulative or noncumulative;

(C) The right, if any, of the holders of such series of Preferred Stock to convert the same into, or exchange the same for, shares of any other class or classes or of any other series of the same or any other class or classes of capital stock, obligations, indebtedness, rights to purchase securities or other securities of the Corporation or other entities, domestic or foreign, or for other property or for any combination of the foregoing, and the terms and conditions of such conversion or exchange;

(D) Whether or not shares of such series of Preferred Stock shall be subject to redemption, and the redemption price or prices and the time or times at which, and the terms and conditions on which, shares of such series of Preferred Stock may be redeemed;

(E) The rights, if any, of the holders of such series of Preferred Stock upon the voluntary or involuntary liquidation, dissolution or winding-up of the Corporation or in the event of any merger or consolidation of or sale of assets by the Corporation;

(F) The terms of any sinking fund or redemption or repurchase or purchase account, if any, to be provided for shares of such series of Preferred Stock;

(G) The voting powers, if any, of the holders of any series of Preferred Stock generally or with respect to any particular matter, which may be less than, equal to or greater than one vote per share, and which may, without limiting the generality of the foregoing, include the right, voting as a series of Preferred Stock as a class, to elect one or more directors of the Corporation generally or under such specific circumstances and on such conditions, as shall be provided in the resolution or resolutions of the Board of Directors adopted pursuant hereto, including, without limitation, in the event there shall have been a default in the payment of dividends on or redemption of any one or more series of Preferred Stock; and

(H) Such other powers, preferences and relative, participating, optional and other special rights, and the qualifications, limitations and restrictions thereof, as the Board of Directors shall determine.

Section 4.3. PREFERENCES, LIMITATIONS AND RELATIVE RIGHTS OF ALL CLASSES OF CAPITAL STOCK.

(A) GENERAL. All shares of Common Stock shall have rights identical to those of all other such shares. Except as they may vary among series established pursuant to

-2-

Section 4.2 of this Article Four, all shares of Preferred Stock shall have preferences, limitations, and relative rights identical to those of all other such shares.

(B) LIQUIDATION PREFERENCE. In the event of dissolution, liquidation, or winding up of the Corporation (whether voluntary or involuntary), after payment or provision for payment of debts but before any distribution to the holders of Common Stock, the holders of each series of Preferred Stock then outstanding shall be entitled to receive the amount fixed by the Board of Directors pursuant to Section 4.2 of this Article Four and no more. All remaining assets shall be distributed pro rata among the holders of Common Stock. If the assets distributable among the holders of Preferred Stock are insufficient to permit full payment to them, the entire assets shall be distributed among the holders of the Preferred Stock in proportion to their respective liquidation preferences unless otherwise provided by the Board of Directors pursuant to Section 4.2 of this Article Four. Neither the consolida tion, merger, or reorganization of the Corporation with any other corporation or corporations, nor the sale of all or substantially all the assets of the Corporation, nor the purchase or redemption by the Corporation of any of its outstanding shares shall be deemed to be a dissolution, liquidation, or winding up within the meaning of this paragraph.

(C) REDEMPTION.

(1) RIGHT; METHOD. All or any part of any one or more series of Preferred Stock may be redeemed at any time or times at the option of the Corporation, by resolution of the Board of Directors, in accordance with the terms and conditions of this Article Four and those fixed by the Board of Directors pursuant to Section 4.2 of this Article Four. The Corporation may redeem shares of any one or more series without redeeming shares of any other series. If less than all the shares of any series are to be redeemed, the shares of the series to be redeemed shall be selected ratably or by lot or by any other equitable method determined by the Board of Directors.

(2) NOTICE. Notice shall be given to the holders of shares to be redeemed, either personally or by mail, not less than twenty nor more than fifty days before the date fixed for redemption.

(3) PAYMENT. Holders of redeemed shares shall be paid in cash the amount fixed by the Board of Directors pursuant to Section 4.2 of this Article Four.

(4) PROVISION FOR PAYMENT. On or before the date fixed for redemption, the Corporation may provide for payment of a sum sufficient to redeem the shares called for redemption either (a) by setting aside the sum, separate from its other funds, in trust for the benefit of the holders of the shares to be redeemed, or (b) by depositing such sum in a bank or trust company (either one in Texas having capital and surplus of at least $10,000,000 according to its latest statement of condition, or one anywhere in the United States duly appointed and acting as transfer agent of the Corporation) as a trust fund, with irrevocable instructions and authority to the bank or trust company to give or complete the notice of

-3-

redemption and to pay to the holders of the shares to be redeemed, on or after the date fixed for redemption, the redemption price on surrender of their respective share certificates. The holders of shares to be redeemed may be evidenced by a list certified by the Corporation (by its president or a vice president and by its secretary or an assistant secretary) or by its transfer agent. If the Corporation so provides for payment, then from and after the date fixed for redemption (a) the shares shall be deemed to be redeemed, (b) dividends thereon shall cease to accrue, (c) such setting aside or deposit shall be deemed to constitute full payment for the shares, (d) the shares shall no longer be deemed to be outstanding, (e) the holders thereof shall cease to be shareholders with respect to such shares, and (f) the holders shall have no rights with respect thereto except the right to receive (without interest) their proportionate shares of the funds so set aside or deposited upon surrender of their respective certificates, and any right to convert such shares which may exist. Any interest accrued on funds so set aside or deposited shall belong to the Corporation. If the holders of the shares do not, within six years after such deposit, claim any amount so deposited for redemption thereof, the bank or trust company shall upon demand pay over to the Corporation the balance of the funds so deposited, and the bank or trust company shall thereupon be relieved of all responsibility to such holders.

(5) STATUS OF REDEEMED SHARES. Shares of Preferred Stock which are redeemed shall be canceled and shall be restored to the status of authorized but unissued shares.

(D) PURCHASE. Except as fixed by the Board of Directors pursuant to
Section 4.2 of this Article Four or as otherwise expressly provided by law, nothing herein shall limit the right of the Corporation to purchase any of its outstanding shares in accordance with law, by public or private transaction.

ARTICLE 5.

The Corporation will not commence business until it has received for the issuance of its shares consideration of the value of at least $1,000.00, consisting of money, labor done or property actually received.

ARTICLE 6.

Without necessity for action by its shareholders, the Corporation may purchase, directly or indirectly, its own shares to the extent of the aggregate of unrestricted capital surplus available therefor and unrestricted reduction surplus available therefor.

ARTICLE 7.

No contract or other transaction between the Corporation and one or more of its directors, officers or securityholders or between the Corporation and another corporation, partnership, joint venture, trust or other enterprise of which one or more of the Corporation's directors, officers or

-4-

securityholders are members, officers, securityholders, directors or employees or in which they are otherwise interested, directly or indirectly, shall be invalid solely because of such relationship, or solely because such director, officer or securityholder is present at or participates in the meeting of the Board of Directors or committee thereof which authorizes the contract or other transaction, or solely because his or their votes are counted for such purpose, if: (a) the material facts as to his relationship or interest and as to the contract or other transaction are known or disclosed to the Board of Directors or committee thereof, and such board or committee in good faith authorizes the contract or other transaction by the affirmative votes of a majority of the disinterested directors even though the disinterested directors be less than a quorum; or (b) the material facts as to his relationship or interest and as to the contract or other transaction are known or disclosed to the shareholders entitled to vote thereon, and the contract or other transaction is specifically approved in good faith by vote of the shareholders; or (c) the contract or other transaction is fair as to the Corporation as of the time it is authorized, approved or ratified by the Board of Directors, a committee thereof, or the shareholders.

ARTICLE 8.

Section 8.1 INDEMNIFICATION. As permitted by Section G of Article 2.02-1 of the Texas Business Corporation Act or any successor statute (the "Indemnification Article"), the Corporation hereby:

(A) makes mandatory the indemnification permitted under Section B of the Indemnification Article as contemplated by Section G thereof;

(B) makes mandatory its payment or reimbursement of the reasonable expenses incurred by a former or present director who was, is, or is threatened to be made a named defendant or respondent in a proceeding upon such director's compliance with the requirements of Section K of the Indemnification Article; and

(C) extends the mandatory indemnification referred to in Section 8.1(a) above and the mandatory payment or reimbursement of expenses referred to in Section 8.1(b) above (i) to all former or present officers of the Corporation and (ii) to all persons who are or were serving at the request of the Corporation as a director, officer, partner or trustee of another foreign or domestic corporation, partnership, joint venture, trust or employee benefit plan, to the same extent that the Corporation is obligated to indemnify and pay or reimburse expenses to directors.

Section 8.2 NONEXCLUSIVITY. The indemnification provided by this Article shall not be deemed exclusive of any other rights to which the person indemnified may be entitled under any bylaw, agreement, authorization of shareholders or disinterested directors or otherwise, both as to action in such person's official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director, officer, employee or agent and shall enure to the benefit of such person's heirs and legal representatives.

-5-

Section 8.3 INSURANCE. The Corporation shall have power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee, or agent of the Corporation or who is or was serving at the request of the Corporation as a director, officer, partner, venturer, proprietor, trustee, employee, agent or similar functionary of another business, foreign, domestic or non-profit corporation, partnership, joint venture, sole proprietorship, trust or other enterprise or employee benefit plan, against any liability asserted against such person and incurred by such person in such a capacity or arising out of such person's status as such a person, whether or not the Corporation would have the power to indemnify such person against that liability under the provisions of this Article or the Texas Business Corporation Act.

Section 8.4 WITNESSES. Notwithstanding any other provision of this Article, the Corporation shall pay or reimburse expenses incurred by any director, officer, employee or agent in connection with such person's appearance as a witness or other participation in a proceeding at a time when such person is not a named defendant or respondent in such proceeding.

ARTICLE 9.

In performing his duties, a director of the Corporation shall be entitled to rely on information, opinions, reports or statements, including financial statements and other financial data, in each case prepared or presented by: (a) one or more officers or employees of the Corporation whom the director reasonably believes to be reliable and competent in the matters presented, (b) counsel, public accountants or other persons as to matters which the director reasonably believes to be within such person's professional or expert competence, or (c) a committee of the Board of Directors upon which he does not serve, duly designed in accordance with a provision of the by-laws, as to matters within its designated authority, which committee the director deems to merit confidence, but he shall not be considered to be acting in good faith if he has knowledge concerning the matter in question that would cause such reliance to be unwarranted.

SECTION 1.1. REGISTERED OFFICE. The registered office of the Corporation required by the State of Texas to be maintained in the State of Texas shall be the registered office named in the Articles of Incorporation of the Corporation, or such other office as may be designated from time to time by the Board of Directors in the manner provided by law.

SECTION 1.2. OTHER OFFICES. The Corporation may also have offices at such other places both within and without the State of Texas as the Board of Directors may from time to time determine or the business of the Corporation may require.

Article 2
SHAREHOLDERS

SECTION 2.1. PLACE OF MEETINGS. All meetings of the shareholders shall be held at the principal office of the Corporation, or at such other place within or without the State of Texas as shall be specified or fixed in the notices or waivers of notice thereof.

SECTION 2.2. QUORUM; ADJOURNMENT OF MEETINGS. Unless otherwise required by law or provided in the Articles of Incorporation of the Corporation or these Bylaws, the holders of a majority of the stock issued and outstanding and entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum at any meeting of shareholders for the transaction of business. The shareholders present at a duly organized meeting may continue to transact business until adjournment, notwithstanding the withdrawal of enough shareholders to leave less than a quorum.

Notwithstanding the other provisions of the Articles of Incorporation of the Corporation or these Bylaws, the chairman of the meeting or the holders of a majority of the issued and outstanding stock, present in person or represented by proxy and entitled to vote thereat, at any meeting of shareholders, whether or not a quorum is present, shall have the power to adjourn such meeting from time to time, without any notice other than announcement at the meeting of the time and place of the


holding of the adjourned meeting. If the adjournment is for more than thirty
(30) days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each shareholder of record entitled to vote at such meeting. At such adjourned meeting at which a quorum shall be present or represented any business may be transacted which might have been transacted at the meeting as originally called.

SECTION 2.3. ANNUAL MEETINGS. An annual meeting of the shareholders, for the election of directors to succeed those whose terms expire and for the transaction of such other business as may properly come before the meeting, shall be held at such place (within or without the State of Texas), on such date, and at such time as the Board of Directors shall fix and set forth in the notice of the meeting, which date shall be within thirteen (13) months subsequent to the last annual meeting of shareholders.

SECTION 2.4. SPECIAL MEETINGS. Unless otherwise provided in the Articles of Incorporation of the Corporation, special meetings of the shareholders for any purpose or purposes may be called at any time by the Chairman of the Board, by the President, by a majority of the Board of Directors, or by a majority of the executive committee (if any) or by the holders of 50% of the outstanding shares of the Company entitled to vote at the proposed special meeting, at such time and at such place as may be stated in the notice of the meeting. Business transacted at a special meeting shall be confined to the purpose(s) stated in the notice of such meeting.

SECTION 2.5. RECORD DATE. For the purpose of determining shareholders entitled to notice of or to vote at any meeting of shareholders, or any adjournment thereof, or entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board of Directors of the Corporation may fix a date as the record date for any such determination of shareholders, which record date shall not precede the date on which the resolutions fixing the record date are adopted and which record date shall not be more than sixty (60) days nor less than ten (10) days before the date of such meeting of shareholders, nor more than sixty (60) days prior to any other action to which such record date relates.

If the Board of Directors does not fix a record date for any meeting of the shareholders, the record date for determining shareholders entitled to notice of or to vote at such meeting shall be at the close of business on the day next preceding the day on which notice is given, or, if in accordance with Article 7, Section 7.3 of these Bylaws notice is waived, at the close of business on the day next preceding the day on which the meeting is held. The record date for determining shareholders for any other purpose (other than the consenting to corporate action in writing without a meeting) shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto. A determination of shareholders of record entitled to notice of or to vote at a meeting of

-2-

shareholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting.

For the purpose of determining the shareholders entitled to consent to corporate action in writing without a meeting, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which date shall not be more than ten (10) days after the date upon which the resolution fixing the record date is adopted by the Board of Directors. If the Board of Directors does not fix the record date, the record date for determining shareholders entitled to consent to corporate action in writing without a meeting, when no prior action by the Board of Directors is necessary, shall be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation at its registered office in the State of Texas or at its principal place of business. If the Board of Directors does not fix the record date, and prior action by the Board of Directors is necessary, the record date for determining shareholders entitled to consent to corporate action in writing without a meeting shall be at the close of business on the day on which the Board of Directors adopts the resolution taking such prior action.

SECTION 2.6. NOTICE OF MEETINGS. Written notice of the place, date and hour of all meetings, and, in case of a special meeting, the purpose or purposes for which the meeting is called, shall be given by or at the direction of the Board of Directors or the other person(s) calling the meeting to each shareholder entitled to vote thereat not less than ten (10) nor more than sixty
(60) days before the date of the meeting. Such notice may be delivered either personally or by mail. If mailed, notice is given when deposited in the United States mail, postage prepaid, directed to the shareholder at such shareholder's address as it appears on the records of the Corporation.

SECTION 2.7. SHAREHOLDER LIST. A complete list of shareholders entitled to vote at any meeting of shareholders, arranged in alphabetical order for each class of stock and showing the address of each such shareholder and the number of shares registered in the name of such shareholder, shall be open to the examination of any shareholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten (10) days prior to the meeting, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting, or, if not so specified, at the place where the meeting is to be held. The shareholder list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any shareholder who is present.

SECTION 2.8. PROXIES. Each shareholder entitled to vote at a meeting of shareholders or to express consent or dissent to a corporate action in writing without a meeting may authorize another person or persons to act for him by proxy. Proxies for use at any meeting of shareholders shall be filed with the Secretary, or such other officer as the Board of Directors may from time to time

-3-

determine by resolution, before or at the time of the meeting. All proxies shall be received and taken charge of and all ballots shall be received and canvassed by the secretary of the meeting, who shall decide all questions touching upon the qualification of voters, the validity of the proxies, and the acceptance or rejection of votes, unless an inspector or inspectors shall have been appointed by the chairman of the meeting, in which event such inspector or inspectors shall decide all such questions.

No proxy shall be valid after eleven (11) months from its date, unless the proxy provides for a longer period. Each proxy shall be revocable unless expressly provided therein to be irrevocable and coupled with an interest sufficient in law to support an irrevocable power.

Should a proxy designate two or more persons to act as proxies, unless such instrument shall provide the contrary, a majority of such persons present at any meeting at which their powers thereunder are to be exercised shall have and may exercise all the powers of voting or giving consents thereby conferred, or if only one be present, then such powers may be exercised by that one; or, if an even number attend and a majority do not agree on any particular issue, each proxy so attending shall be entitled to exercise such powers in respect of such portion of the shares as is equal to the reciprocal of the fraction equal to the number of proxies representing such shares divided by the total number of shares represented by such proxies.

SECTION 2.9. VOTING; ELECTION; INSPECTORS. Unless otherwise required by law or provided in the Articles of Incorporation of the Corporation, each shareholder shall on each matter submitted to a vote at a meeting of shareholders have one vote for each share of the stock entitled to vote which is registered in his name on the record date for the meeting. For the purposes hereof, each election to fill a directorship shall constitute a separate matter. Shares registered in the name of another corporation, domestic or foreign, may be voted by such officer, agent or proxy as the bylaws (or comparable body) of such corporation may determine. Shares registered in the name of a deceased person may be voted by the executor or administrator of such person's estate, either in person or by proxy.

All voting, except as required by the Articles of Incorporation of the Corporation or where otherwise required by law, may be by a voice vote; provided, however, upon request of the chairman of the meeting or upon demand therefor by shareholders holding a majority of the issued and outstanding stock present in person or by proxy at any meeting a stock vote shall be taken. Every stock vote shall be taken by written ballots, each of which shall state the name of the shareholder or proxy voting and such other information as may be required under the procedure established for the meeting. All elections of directors shall be by written ballots, unless otherwise provided in the Articles of Incorporation of the Corporation.

-4-

At any meeting at which a vote is taken by written ballots, the chairman of the meeting may appoint one or more inspectors, each of whom shall subscribe an oath or affirmation to execute faithfully the duties of inspector at such meeting with strict impartiality and according to the best of such inspector's ability. Such inspector shall receive the written ballots, count the votes, and make and sign a certificate of the result thereof. The chairman of the meeting may appoint any person to serve as inspector, except no candidate for the office of director shall be appointed as an inspector.

Unless otherwise provided in the Articles of Incorporation of the Corporation, cumulative voting for the election of directors shall be prohibited.

SECTION 2.10. CONDUCT OF MEETINGS. The meetings of the shareholders shall be presided over by the Chairman of the Board, or, if the Chairman of the Board is not present, by the President, or, if the President is not present, by any Vice President, or if no Vice President is present, by a chairman elected at the meeting. The Secretary of the Corporation, if present, shall act as secretary of such meetings, or, if the Secretary is not present, an Assistant Secretary shall so act; if neither the Secretary or an Assistant Secretary is present, then a secretary shall be appointed by the chairman of the meeting.

The chairman of any meeting of shareholders shall determine the order of business and the procedure at the meeting, including such regulation of the manner of voting and the conduct of discussion as seem to the chairman in order.

SECTION 2.11. NOTIFICATIONS OF NOMINATIONS AND PROPOSED BUSINESS. Subject to the rights of holders of any class of capital stock of the Corporation (other than the common stock), nominations for the election of directors and proposals for business to be brought before any shareholder meeting may be made by the Board of Directors or by any shareholder entitled to vote in the election of directors generally. However, any such shareholder may nominate one or more persons for election as directors at a meeting or propose business to be brought before a meeting, or both, only if such shareholder has given timely notice in proper written form of his intent to make such nomination or nominations or to propose such business. To be timely, a shareholder's notice must be delivered to or mailed and received by the Secretary of the Corporation not later than sixty
(60) days prior to such meeting. To be in proper written form, a shareholder's notice to the Secretary shall set forth:

(i) the name and address of the shareholder who intends to make the nominations or propose the business and, in the case of nominations for the election of directors, of the person or persons to be nominated;

-5-

(ii) a representation that the shareholder is a holder of record of stock of the Corporation entitled to vote at such meeting and, if applicable, intends to appear in person or by proxy at the meeting to nominate the person or persons specified in the notice or propose the business specified in the notice;

(iii) if applicable, a description of all arrangements or understandings between the shareholder and each nominee and any other person or persons (naming such person or persons) pursuant to which the nomination or nominations are to be made by the shareholder;

(iv) such other information regarding each nominee or each matter of business to be proposed by such shareholder as would be required to be included in a proxy statement filed pursuant to the proxy rules of the Securities and Exchange Commission had the nominee been nominated or the matter been proposed by the Board of Directors; and

(v) if applicable, the consent of each nominee to serve as director of the Corporation if so elected.

A nomination of any person or proposal of any business not made in compliance with the foregoing procedures shall not be eligible to be voted upon by the shareholders at the meeting.

SECTION 2.12.TREASURY STOCK. The Corporation shall not vote, directly or indirectly, shares of its own stock owned by it and such shares shall not be counted for quorum purposes. Nothing in this Section 2.11 shall be construed as limiting the right of the Corporation to vote stock, including but not limited to its own stock, held by it in a fiduciary capacity.

Article 3
BOARD OF DIRECTORS

SECTION 3.1.POWER; NUMBER; TERM OF OFFICE. The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors, and, subject to the restrictions imposed by law or the Articles of Incorporation of the Corporation, the Board of Directors may exercise all the powers of the Corporation.

The number of directors which shall constitute the whole Board of Directors shall be determined from time to time by the Board of Directors (provided that no decrease in the number of directors which would have the effect of shortening the term of an incumbent director may be made by the Board of Directors). If the Board of Directors makes no such determination, the number of directors shall be three. Each director shall hold office for the term for which such director is

-6-

elected, and until such director's successor shall have been elected and qualified or until such director's earlier death, resignation or removal.

Unless otherwise provided in the Articles of Incorporation of the Corporation, directors need not be shareholders nor residents of the State of Texas.

SECTION 3.2.CLASSIFIED BOARD. The directors of the Corporation shall be divided into three classes, with respect to the time that they severally hold office, as nearly equal in number as possible, with the initial term of office of the first class of directors (the "Class I Directors") to expire at the 1999 annual meeting of holders of capital stock of the Corporation, the initial term of office of the second class of directors (the "Class II Directors") to expire at the 2000 annual meeting of holders of capital stock of the Corporation and the initial term of office of the third class of directors (the "Class III Directors") to expire at the 2001 annual meeting of holders of capital stock of the Corporation. Directors elected to succeed those directors whose terms have thereupon expired shall be elected for a term of office to expire at the third succeeding annual meeting of holders of capital stock of the Corporation after their election. If the number of directors is changed, any increase or decrease shall be apportioned among the classes so as to maintain or attain, if possible, the equality of the number of directors in each class, but in no case will a decrease in the number of directors shorten the term of any incumbent director. If such equality is not possible, the increase or decrease shall be apportioned among the classes in such a way that the difference in the number of directors in any two classes shall not exceed one.

SECTION 3.3.QUORUM; VOTING. Unless otherwise provided in the Articles of Incorporation of the Corporation, a majority of the number of directors fixed in accordance with Section 3.1 shall constitute a quorum for the transaction of business of the Board of Directors and the vote of a majority of the directors present at a meeting at which a quorum is present shall be the act of the Board of Directors.

SECTION 3.4.PLACE OF MEETINGS; ORDER OF BUSINESS. The directors may hold their meetings and may have an office and keep the books of the Corporation, except as otherwise provided by law, in such place or places, within or without the State of Texas, as the Board of Directors may from time to time determine. At all meetings of the Board of Directors business shall be transacted in such order as shall from time to time be determined by the Chairman of the Board, or in the Chairman of the Board's absence by the President, or in the President's absence by the Vice President, or by the Board of Directors.

SECTION 3.5.FIRST MEETING. Each newly elected Board of Directors may hold its first meeting for the purpose of organization and the transaction of business, if a quorum is present, immediately after and at the same place as the annual meeting of the shareholders. Notice of such

-7-

meeting shall not be required. At the first meeting of the Board of Directors in each year at which a quorum shall be present, held after the annual meeting of shareholders, the Board of Directors shall elect the officers of the Corporation.

SECTION 3.6.REGULAR MEETINGS. Regular meetings of the Board of Directors shall be held at such times and places as shall be designated from time to time by the Chairman of the Board, or in the absence of the Chairman of the Board, by the President, or in the President's absence, by the Vice President, or in the absence of the Vice President, by another officer of the Corporation. Notice of such regular meetings shall not be required.

SECTION 3.7.SPECIAL MEETINGS. Special meetings of the Board of Directors may be called by the Chairman of the Board, the President or, on the written request of any director, by the Secretary, in each case on at least twenty-four
(24) hours personal, written, telegraphic, cable or wireless notice to each director. Such notice, or any waiver thereof pursuant to Article 7, Section 7.3 hereof, need not state the purpose or purposes of such meeting, except as may otherwise be required by law or provided for in the Articles of Incorporation of the Corporation or these Bylaws. Meetings may be held at any time without notice if all the directors are present or if those not present waive notice of the meeting in writing.

SECTION 3.8.REMOVAL. Any director or the entire Board of Directors may be removed, but only for cause, by the holders of a majority of the shares then entitled to vote at an election of directors.

SECTION 3.9.VACANCIES; INCREASES IN THE NUMBER OF DIRECTORS. Unless otherwise provided in the Articles of Incorporation of the Corporation, vacancies existing on the Board of Directors for any reason may be filled by the affirmative vote of a majority of the directors then in office, although less than a quorum, or by a sole remaining director; and any director so chosen shall hold office until the next annual meeting held for the election of directors of the class of directors to which such director has been appointed and until such director's successor shall have been elected and qualified, or until such director's earlier death, resignation or removal.

SECTION 3.10.COMPENSATION. Directors and members of standing committees may receive such compensation as the Board of Directors from time to time shall determine to be appropriate, and shall be reimbursed for all reasonable expenses incurred in attending and returning from meetings of the Board of Directors.

SECTION 3.11.ACTION WITHOUT A MEETING; TELEPHONE CONFERENCE MEETING. Unless otherwise restricted by the Articles of Incorporation of the Corporation, any action required or permitted to be taken at any meeting of the Board of Directors or any committee designated by the Board of

-8-

Directors may be taken without a meeting if all members of the Board of Directors or committee, as the case may be, consent thereto in writing, and the writing or writings are filed with the minutes of proceedings of the Board of Directors or committee. Such consent shall have the same force and effect as a unanimous vote at a meeting, and may be stated as such in any document or instrument filed with the Secretary of State of the State of Texas.

Unless otherwise restricted by the Articles of Incorporation of the Corporation, subject to the requirement for notice of meetings, members of the Board of Directors, or members of any committee designated by the Board of Directors, may participate in a meeting of such Board of Directors or committee, as the case may be, by means of a conference telephone connection or similar communications equipment by means of which all persons participating in the meeting can hear each other, and participation in such a meeting shall constitute presence in person at such meeting, except where a person participates in the meeting for the express purpose of objecting to the transaction of any business on the ground that the meeting is not lawfully called or convened.

SECTION 3.12.APPROVAL OR RATIFICATION OF ACTS OR CONTRACTS BY SHAREHOLDERS. The Board of Directors in its discretion may submit any act or contract for approval or ratification at any annual meeting of the shareholders, or at any special meeting of the shareholders called for the purpose of considering any such act or contract, and any act or contract that shall be approved or be ratified by the vote of the shareholders holding a majority of the issued and outstanding shares of stock of the Corporation entitled to vote and present in person or by proxy at such meeting (provided that a quorum is present) shall be as valid and as binding upon the Corporation and upon all the shareholders as if it has been approved or ratified by every shareholder of the Corporation. In addition, any such act or contract may be approved or ratified by the written consent of shareholders holding a majority of the issued and outstanding shares of capital stock of the Corporation entitled to vote, and such consent shall be as valid and binding upon the Corporation and upon all the shareholders as if it had been approved or ratified by every shareholder of the Corporation.

Article 4
COMMITTEES

SECTION 6.1.CERTIFICATES OF STOCK. The certificates for shares of the capital stock of the Corporation shall be in such form, not inconsistent with that required by law and the Articles of Incorporation of the Corporation, as shall be approved by the Board of Directors. Every holder of stock represented by certificates shall be entitled to have a certificate signed by or in the name of the Corporation by the Chairman of the Board, the President or a Vice President and the Secretary or an Assistant Secretary or the Treasurer or an Assistant Treasurer of the Corporation representing the number of shares (and, if the stock of the Corporation shall be divided into classes or series, certifying the class and series of such shares) owned by such shareholder which are registered in certified form; provided, however, that any of or all the signatures on the certificate may be facsimile. The stock record books and the blank stock certificate books shall be kept by the Secretary or at the office of such transfer agent or transfer agents as the Board of Directors may from time to time determine. In case any officer, transfer agent or registrar who shall have signed or whose facsimile signature or signatures shall have been placed upon any such certificate or certificates shall have ceased to be such officer, transfer agent or registrar before such certificate is issued by the Corporation, such certificate may nevertheless be issued by the Corporation with the same effect as if such person were such officer, transfer agent or registrar at the date of issue. The stock certificates shall be consecutively numbered and shall be entered in the books of the Corporation as they are issued and shall exhibit the holder's name and number of shares.

SECTION 6.2.TRANSFER OF SHARES. The shares of stock of the Corporation shall be transferable only on the books of the Corporation by the holders thereof in person or by their duly authorized attorneys or legal representatives upon surrender and cancellation of certificates for a like number of shares. Upon surrender to the Corporation or a transfer agent of the Corporation of a certificate for shares duly endorsed or accompanied by proper evidence of succession, assignment or authority to transfer, it shall be the duty of the Corporation to issue a new certificate to the person entitled thereto, cancel the old certificate and record the transaction upon its books.

SECTION 6.3.OWNERSHIP OF SHARES. The Corporation shall be entitled to treat the holder of record of any share or shares of capital stock of the Corporation as the holder in fact thereof and, accordingly, shall not be bound to recognize any equitable or other claim to or interest in such share or shares on the part of any other person, whether or not it shall have express or other notice thereof, except as otherwise provided by the laws of the State of Texas.

Duplicates of the seal may be kept for use by any Assistant Secretary.

SECTION 7.3.NOTICE AND WAIVER OF NOTICE.

Whenever notice is required to be given by law, the Articles of Incorporation of the Corporation or under any of the provisions of these Bylaws, a written waiver thereof, signed by the person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to notice. Attendance of a person, including without limitation a director, at a meeting shall constitute a waiver of notice of such meeting, except when the person attends a meeting for the

-14-

express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the shareholders, directors, or members of a committee of directors need be specified in any written waiver of notice unless so required by the Articles of Incorporation of the Corporation or these Bylaws.

SECTION 7.4.FACSIMILE SIGNATURES. In addition to the provisions for the use of facsimile signatures elsewhere specifically authorized in these Bylaws, facsimile signatures of any officer or officers of the Corporation may be used whenever and as authorized by the Board of Directors.

EXHIBIT 10.1

PROSPERITY BANCSHARES, INC.
STOCK OPTION PLAN

SECTION 1. PURPOSE OF THE PLAN. The purpose of the Prosperity Bancshares, Inc. Stock Option Plan, ("Plan") is to encourage ownership of common stock, $1.00 par value ("Common Stock"), of Prosperity Bancshares, Inc., a Texas corporation (the "Company"), by the executive officers and key employees of the Company and its Affiliates (as defined below) and to provide increased incentive for such officers and employees to render services and to exert maximum effort for the success of the Company's business. In addition, the Company expects that the Plan will further strengthen the identification of the executive officers and key employees with the stockholders. Certain options to be granted under this Plan are intended to qualify as Incentive Stock Options ("ISOs") pursuant to Section 422 of the Internal Revenue Code of 1986, as amended ("Code"), while other options granted under this Plan will be nonqualified options which are not intended to qualify as ISOs ("Nonqualified Options"), either or both as provided in the agreements evidencing the options as provided in Section 6 hereof. As used in this Plan, the term "Affiliates" means any "parent corporation" of the Company and any "subsidiary corporation" of the Company within the meaning of Code Sections 424(e) and (f), respectively.

SECTION 2. ADMINISTRATION OF THE PLAN.

(a) COMPOSITION OF THE ADMINISTRATION COMMITTEE. The Plan shall be administered by the Board of Directors of the Company (the "Board") or any committee appointed by the Board to administer the Plan. The Board in its capacity as the administrator of the Plan or any committee appointed by the Board to administer the Plan shall both be referred to herein as the "Committee".

(b) COMMITTEE ACTION. The Committee shall hold its meetings at such times and places as it may determine. A majority of its members shall constitute a quorum, and all determinations of the Committee shall be made by not less than a majority of its members. Any decision or determination reduced to writing and signed by a majority of the members shall be fully as effective as if it had been made by a majority vote of its members at a meeting duly called and held. The Committee may designate the Secretary of the Company or other Company employees to assist the Committee in the administration of the Plan, and may grant authority to such persons to execute award agreements or other documents on behalf of the Committee and the Company. Any duly constituted committee of the Board satisfying the qualifications of this Section 2 may be appointed as the Committee.

(c) COMMITTEE EXPENSES. All expenses and liabilities incurred by the Committee in the administration of the Plan shall be borne by the Company. The Committee may employ attorneys, consultants, accountants or other persons.

SECTION 3. STOCK RESERVED FOR THE PLAN. Subject to adjustment as provided in Section 6 hereof, the aggregate number of shares of Common Stock that may be optioned under the Plan is 85,000. The shares subject to the Plan shall consist of authorized but unissued shares of Common


Stock and such number of shares shall be and is hereby reserved for sale for such purpose. Any of such shares which may remain unsold and which are not subject to outstanding options at the termination of the Plan shall cease to be reserved for the purpose of the Plan, but until termination of the Plan or the termination of the last of the options granted under the Plan, whichever last occurs, the Company shall at all times reserve a sufficient number of shares to meet the requirements of the Plan. Should any option expire or be cancelled prior to its exercise in full, the shares theretofore subject to such option may again be made subject to an option under the Plan.

SECTION 4. ELIGIBILITY. The persons eligible to participate in the Plan as a recipient of options ("Optionee") shall include only executive officers and key employees of the Company or its Affiliates at the time the option is granted. An executive officer or key employee who has been granted an option hereunder may be granted an additional option or options, if the Committee shall so determine.

SECTION 5. GRANT OF OPTIONS.

(a) COMMITTEE DISCRETION. The Committee shall have sole and absolute discretionary authority (i) to determine, authorize, and designate those persons pursuant to this Plan who are to receive options under the Plan,
(ii) to determine the number of shares of Common Stock to be covered by such options and the terms thereof, and (iii) to determine the type of option granted: ISO, Nonqualified Option or a combination of ISO and Nonqualified Options. The Committee shall thereupon grant options in accordance with such determinations as evidenced by a written option agreement. Subject to the express provisions of the Plan, the Committee shall have discretionary authority to prescribe, amend and rescind rules and regulations relating to the Plan, to interpret the Plan, to prescribe the terms of the option agreements (which need not be identical), to amend the terms of the option agreements (provided that no amendment shall impair the rights of an Optionee, without the Optionee's consent) and to make all other determinations deemed necessary or advisable for the administration of the Plan.

(b) STOCKHOLDER APPROVAL. The Plan shall be approved by the holders of a majority of the outstanding shares of Common Stock.

(c) LIMITATION ON INCENTIVE STOCK OPTIONS. The aggregate fair market value (determined in accordance with Section 6(b) of this Plan at the time the option is granted) of the Common Stock with respect to which ISOs may be exercisable for the first time by any Optionee during any calendar year under all such plans of the Company and its Affiliates shall not exceed $100,000.

SECTION 6. TERMS AND CONDITIONS. Each option granted under the Plan shall be evidenced by an agreement, in a form approved by the Committee, which shall be subject to the following express terms and conditions and to such other terms and conditions as the Committee may deem appropriate.

-2-

(a) OPTION PERIOD. The Committee shall promptly notify the Optionee of the option grant and a written agreement shall promptly be executed and delivered by and on behalf of the Company and the Optionee, provided that the option grant shall expire if a written agreement is not signed by said Optionee (or his agent or attorney) and returned to the Company within 60 days from date of receipt by the Optionee of such agreement. The date of grant shall be the date the option is actually granted by the Committee, even though the written agreement may be executed and delivered by the Company and the Optionee after that date. Each option agreement shall specify the period for which the option thereunder is granted (which in no event shall exceed ten years from the date of grant) and shall provide that the option shall expire at the end of such period. If the original term of an option is less than ten years from the date of grant, the option may be amended prior to its expiration, with the approval of the Committee and the Optionee, to extend the term so that the term as amended is not more than ten years from the date of grant. However, in the case of an ISO granted to an individual who, at the time of grant, owns stock possessing more than 10 percent of the total combined voting power of all classes of stock of the Company or its Affiliate ("Ten Percent Stockholder"), such period shall not exceed five years from the date of grant.

(b) OPTION PRICE. The purchase price of each share of Common Stock subject to a Nonqualified Option under this Plan shall be the "Book Value" of a share of Common Stock as of a date to be determined by the Committee. "Book Value" shall mean the total net worth of the Company (i.e., stockholders equity) divided by the number of shares outstanding. The purchase price of each share of Common Stock subject to an ISO shall be determined by the Committee at the time the option is granted and shall not be less than 100% of the fair market value of a share of Common Stock on the date the option is granted, as determined by the Committee. In the case of ISOs granted to a Ten Percent Stockholder, the exercise price shall not be less than 110% of the fair market value of a share of Common Stock on the date the option is granted.

For all purposes under this Plan, the determination of the fair market value of a share of Common Stock on a particular date shall be made by the Committee in such manner as it deems appropriate.

(c) EXERCISE PERIOD. The Committee may provide in the option agreement that an option may be exercised in whole, immediately, or is to be exercisable in increments. However, no portion of any option may be exercisable by an Optionee prior to the approval of this Plan by the shareholders of the Company.

(d) PROCEDURE FOR EXERCISE. Options shall be exercised by the delivery of written notice to the Secretary of the Company setting forth the number of shares with respect to which the option is being exercised. Such notice shall be accompanied by cash or cashier's check, bank draft, postal or express money order payable to the order of the Company, or Common Stock theretofore owned by such Optionee (or any combination of cash and Common Stock). Notice may also be delivered by fax or telecopy provided that the

-3-

purchase price of such shares is delivered to the Company via wire transfer on the same day the fax is received by the Company. The notice shall specify the address to which the certificates for such shares are to be mailed. An Optionee shall be deemed to be a stockholder with respect to shares covered by an option on the date the Company receives such written notice and such option payment. As promptly as practicable after receipt of such written notification and payment, the Company shall deliver to the Optionee certificates for the number of shares with respect to which such option has been so exercised, issued in the Optionee's name or such other name as Optionee directs; provided, however, that such delivery shall be deemed effected for all purposes when a stock transfer agent of the Company shall have deposited such certificates in the United States mail, addressed to the Optionee at the address specified pursuant to this Section 6(d).

(e) TERMINATION OF EMPLOYMENT. If an Optionee to whom an option is granted ceases to be employed by the Company for any reason other than death or disability, any option which is exercisable on the date of such termination of employment may be exercised during a period beginning on such date and ending at the time set forth in the option agreement; provided, however, that if an Optionee's employment is terminated because of the Optionee's theft or embezzlement from the Company, disclosure of trade secrets of the Company or the commission of a willful, felonious act while in the employment of the Company (such reasons shall hereinafter be collectively referred to as "for cause"), then any option or unexercised portion thereof granted to said Optionee shall expire upon such termination of employment. Notwithstanding the foregoing, no ISO may be exercised later than three months after an employee's termination of employment for any reason other than death or disability.

(f) DISABILITY OR DEATH OF OPTIONEE. In the event the Optionee dies or is determined under this Plan to be disabled while the Optionee is employed by the Company, the options previously granted to the Optionee may be exercised (whether or not exercisable on the date of death or the determination of disability) at any time and from time to time, within a period beginning on the date of such determination of disability or death and ending at the time set forth in the option agreement, by the Optionee, the guardian of the Optionee's estate, the executor or administrator of the Optionee's estate or by the person or persons to whom the Optionee's rights under the option shall pass by will or the laws of descent and distribution, but in no event may the option be exercised after its expiration under the terms of the option agreement. Notwithstanding the foregoing, no ISO may be exercised later than one year after the determination of disability or death. An Optionee shall be deemed to be disabled if, in the opinion of a physician selected by the Committee, the Optionee is incapable of performing services for the Company of the kind the Optionee was performing at the time the disability occurred by reason of any medically determinable physical or mental impairment which can be expected to result in death or to be of long, continued and indefinite duration. The date of determination of disability for purposes hereof shall be the date of such determination by such physician.

-4-

(g) ASSIGNABILITY. An option shall not be assignable or otherwise transferable except by will or by the laws of descent and distribution or the rules thereunder. During the lifetime of an Optionee, an option shall be exercisable only by him.

(h) INCENTIVE STOCK OPTIONS. Each option agreement may contain such terms and provisions as the Committee may determine to be necessary or desirable in order to qualify under the Code an option designated as an incentive stock option.

(i) NO RIGHTS AS STOCKHOLDER. No Optionee shall have any rights as a stockholder with respect to shares covered by an option until the option is exercised by the written notice and accompanied by payment as provided in clause (d) above.

(j) EXTRAORDINARY CORPORATE TRANSACTIONS. The existence of outstanding options shall not affect in any way the right or power of the Company or its shareholders to make or authorize any or all adjustments, recapitalizations, reorganizations, exchanges, or other changes in the Company's capital structure or its business, or any merger or consolidation of the Company, or any issuance of Common Stock or other securities or subscription rights thereto, or any issuance of bonds, debentures, preferred or prior preference stock ahead of or affecting the Common Stock or the rights thereof, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise. If the Company recapitalizes or otherwise changes its capital structure, or merges, consolidates, sells all of its assets or dissolves (each of the foregoing a "Fundamental Change"), then thereafter upon any exercise of an option theretofore granted the Optionee shall be entitled to purchase under such option, in lieu of the number of shares of Common Stock as to which option shall then be exercisable, the number and class of shares of stock and securities to which the Optionee would have been entitled pursuant to the terms of the Fundamental Change if, immediately prior to such Fundamental Change, the Optionee had been the holder of record of the number of shares of Common Stock as to which such option is then exercisable. If (i) the Company shall not be the surviving entity in any merger or consolidation (or survives only as a subsidiary of another entity), (ii) the Company sells all or substantially all of its assets to any other person or entity (other than a wholly-owned subsidiary), (iii) any person or entity (including a "group" as contemplated by Section 13(d)(3) of the Exchange Act) acquires or gains ownership or control of (including, without limitation, power to vote) more than 50% of the outstanding shares of Common Stock, (iv) the Company is to be dissolved and liquidated, or (v) as a result of or in connection with a contested election of directors, the persons who were directors of the Company before such election shall cease to constitute a majority of the Board (each such event in clauses
(i) through (v) above is referred to herein as a "Corporate Change"), all of an Optionee's options shall immediately become fully vested and exercisable.

(k) CHANGES IN CAPITAL STRUCTURE. If the outstanding shares of Common Stock or other securities of the Company, or both, for which the option is then exercisable shall at any time be changed or exchanged by declaration of a stock dividend, stock split, combination

-5-

of shares or recapitalization, the number and kind of shares of Common Stock or other securities which are subject to this Plan or subject to any options theretofore granted, and the exercise prices, shall be appropriately and equitably adjusted so as to maintain the proportionate number of shares or other securities without changing the aggregate exercise price.

(l) ACCELERATION OF OPTIONS. Except as hereinbefore expressly provided, (i) the issuance by the Company of shares of stock of any class of securities convertible into shares of stock of any class, for cash, property, labor or services, upon direct sale, upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or obligations of the Company convertible into such shares or other securities, (ii) the payment of a dividend in property other than Common Stock, or (iii) the occurrence of any similar transaction, and in any case whether or not for fair value, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number of shares of Common Stock subject to options theretofore granted or the purchase price per share, unless the Committee shall determine in its sole discretion that an adjustment is necessary to provide equitable treatment to Optionee. Notwithstanding anything to the contrary contained in this Plan, the Committee may in its sole discretion accelerate the time at which any option may be exercised, including, but not limited to, upon the occurrence of the events specified in this Section 6.

SECTION 7. AMENDMENTS OR TERMINATION. The Board may amend, alter or discontinue the Plan, but no amendment or alteration shall be made which would impair the rights of any Optionee, without his consent, under any option theretofore granted, or which, without the approval of the stockholders, would:

The Committee may, with the consent of the person entitled to exercise any outstanding option, amend such option, including reducing the exercise price of any option to not less than the fair market value of the Common Stock at the time of the amendment and extending the term thereof.

SECTION 12. NO RIGHT TO COMPANY EMPLOYMENT. Optionees shall be considered to be in the employment of the Company as long as they remain employees of the Company or an Affiliate.

To the extent that an Award lapses or the rights of its Holder terminate, any shares of Stock subject to such Award shall again be available for the grant of an Award. Separate stock certificates shall be issued by the Company for those shares acquired pursuant the exercise of an Incentive Stock Option and for those shares acquired pursuant to the exercise of a Nonqualified Stock Option.

VI. ELIGIBILITY

Awards may be granted to employees of the Company, directors of the Company or other individuals whose contributions to the welfare of the Company are of importance. An Award may be granted on more than one occasion to the same person, and, subject to the limitations set forth in the Plan, such Award may include an Incentive Stock Option or a Nonqualified Stock Option, a Stock Appreciation Right, a Restricted Stock Award, a Performance Award, a Phantom Stock Award or any combination thereof.

(b) LIMITATIONS ON EXERCISE OF OPTION. An Option shall be exercisable in whole or in such installments and at such times as determined by the Committee.

To the extent that the aggregate Fair Market Value (determined at the time the respective Incentive Stock Option is granted) of Stock with respect to which Incentive Stock Options are exercisable for the first time by an individual during any calendar year under all incentive stock option plans of the Company and its parent and subsidiary corporations exceeds $100,000, such Incentive Stock Options shall be treated as Nonqualified Stock Options as determined by the Committee. The Committee shall determine, in accordance with applicable provisions of the Code, Treasury Regulations and other administrative pronouncements, which of an optionee's Incentive Stock Options will not constitute Incentive Stock Options because of such limitation and shall notify the optionee of such determination as soon as practicable after such determination. No Incentive Stock Option shall be granted to an individual if, at the time the Option is granted, such individual owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or of its parent or subsidiary corporation, within the meaning of section 422(b)(6) of the Code, unless (i) at the time such Option is granted the option price is at least 110% of the Fair Market Value of the Stock subject to the Option and (ii) such Option by its terms is not exercisable after the expiration of five years from the date of grant.

(d) OPTION AGREEMENT. Each Option shall be evidenced by an Option Agreement in such form and containing such provisions not inconsistent with the provisions of the Plan as the Committee from time to time shall approve, including, without limitation, provisions to qualify an Incentive Stock Option under section 422 of the Code. An Option Agreement may provide for the payment of the option price, in whole or in part, by the delivery of a number of shares of Stock (plus

-6-

cash if necessary) having a Fair Market Value equal to such option price. Each Option Agreement shall provide that the Option may not be exercised earlier than six months from the date of grant and shall specify the effect of termination of employment on the exercisability of the Option. Moreover, an Option Agreement may provide for a "cashless exercise" of the Option by establishing procedures whereby the Holder, by a properly-executed written notice, directs (i) an immediate market sale or margin loan respecting all or a part of the shares of Stock to which he is entitled upon exercise pursuant to an extension of credit by the Company to the Holder of the option price, (ii) the delivery of the shares of Stock from the Company directly to a brokerage firm and (iii) the delivery of the option price from the sale or margin loan proceeds from the brokerage firm directly to the Company. Such Option Agreement may also include, without limitation, provisions relating to (i) vesting of Options, subject to the provisions hereof accelerating such vesting on a Change of Control, (ii) tax matters (including provisions (y) permitting the delivery of additional shares of Stock or the withholding of shares of Stock from those acquired upon exercise to satisfy federal or state income tax withholding requirements and (z) dealing with any other applicable employee wage withholding requirements), and (iii) any other matters not inconsistent with the terms and provisions of this Plan that the Committee shall in its sole discretion determine. The terms and conditions of the respective Option Agreements need not be identical.

(e) OPTION PRICE AND PAYMENT. The price at which a share of Stock may be purchased upon exercise of an Option shall be determined by the Committee, but
(i) such purchase price shall not be less than the Fair Market Value of Stock subject to an Incentive Stock Option on the date the Incentive Stock Option is granted and (ii) such purchase price shall be subject to adjustment as provided in Paragraph XII. The Option or portion thereof may be exercised by delivery of an irrevocable notice of exercise to the Company. The purchase price of the Option or portion thereof shall be paid in full in the manner prescribed by the Committee.

(f) SHAREHOLDER RIGHTS AND PRIVILEGES. The Holder shall be entitled to all the privileges and rights of a shareholder only with respect to such shares of Stock as have been purchased under the Option and for which certificates of stock have been registered in the Holder's name.

(g) OPTIONS AND RIGHTS IN SUBSTITUTION FOR STOCK OPTIONS GRANTED BY OTHER CORPORATIONS. Options and Stock Appreciation Rights may be granted under the Plan from time to time in substitution for stock options held by individuals employed by corporations who become employees as a result of a merger or consolidation of the employing corporation with the Company or any subsidiary, or the acquisition by the Company or a subsidiary of the assets of the employing corporation, or the acquisition by the Company or a subsidiary of stock of the employing corporation with the result that such employing corporation becomes a subsidiary.

VIII. STOCK APPRECIATION RIGHTS

(a) STOCK APPRECIATION RIGHTS. A Stock Appreciation Right is the right to receive an amount equal to the Spread with respect to a share of Stock upon the exercise of such Stock Appreciation Right. Stock Appreciation Rights may be granted in connection with the grant of an Option, in which case the Option Agreement will provide that exercise of Stock Appreciation Rights will result in the surrender of the right to purchase the shares under the Option as to which the Stock Appreciation Rights were exercised. Alternatively, Stock Appreciation Rights may be granted independently of Options in which case each Award of Stock Appreciation Rights shall be evidenced by a Stock Appreciation Rights Agreement which shall contain such terms and conditions as may be approved by the Committee. The Spread with respect to a Stock Appreciation Right may be payable either in cash, shares of Stock with a Fair Market Value equal to the Spread or in a combination of cash and shares of Stock. With respect to Stock Appreciation Rights that are subject to Section 16 of the 1934 Act, however, the Committee shall, except as provided in Paragraph XII(c), retain sole discretion (i) to determine the form in which payment of the Stock Appreciation Right will be made (I.E., cash, securities or any combination thereof) or (ii) to approve an election by a Holder to receive cash in full or partial settlement of Stock Appreciation Rights. Each Stock Appreciation Rights Agreement shall provide that the Stock Appreciation Rights may not be exercised earlier than six months from the date of grant and shall specify the effect of termination of employment on the exercisability of the Stock Appreciation Rights.

(b) OTHER TERMS AND CONDITIONS. At the time of such Award, the Committee, may in its sole discretion, prescribe additional terms, conditions or restrictions relating to Stock Appreciation Rights, including, but not limited to rules pertaining to termination of employment (by retirement, disability, death or otherwise) of a Holder prior to the expiration of such Stock Appreciation Rights. Such additional terms, conditions or restrictions shall be set forth in the Stock Appreciation Rights Agreement made in conjunction with the Award. Such Stock Appreciation Rights Agreements may also include, without limitation, provisions relating to (i) vesting of Awards, subject to the provisions hereof accelerating vesting on a Change of Control,(ii) tax matters (including provisions covering applicable wage withholding requirements), and
(iii) any other matters not inconsistent with the terms and provisions of this Plan, that the Committee shall in its sole discretion determine. The terms and conditions of the respective Stock Appreciation Rights Agreements need not be identical.

(c) EXERCISE PRICE. The exercise price of each Stock Appreciation Right shall be determined by the Committee, but such exercise price (i) shall not be less than the Fair Market Value of a share of Stock on the date the Stock Appreciation Right is granted (or such greater exercise price as may be required if such Stock Appreciation Right is granted in connection with an Incentive Stock Option that must have an exercise price equal to 110% of the Fair Market Value of the Stock on the

-8-

date of grant pursuant to Paragraph VII(c)), and (ii) shall be subject to adjustment as provided in Paragraph XII.

(d) EXERCISE PERIOD. The term of each Stock Appreciation Right shall be as specified by the Committee at the date of grant.

The Forfeiture Restrictions applicable to a particular Restricted Stock Award shall not be changed except as permitted by Paragraph IX(b) or Paragraph XII.

(b) OTHER TERMS AND CONDITIONS. Stock awarded pursuant to a Restricted Stock Award shall be represented by a stock certificate registered in the name of the Holder of such Restricted Stock Award.

The terms and provisions of the respective agreements need not be identical.

XII. RECAPITALIZATION OR REORGANIZATION

(a) The shares with respect to which Awards may be granted are shares of Stock as presently constituted, but if, and whenever, prior to the expiration of an Award theretofore granted, the Company shall effect a subdivision or consolidation by the Company, the number of shares of Stock with respect to which such Award may thereafter be exercised or satisfied, as applicable, (i) in the event of an increase in the number of outstanding shares shall be proportionately increased, and the purchase price per share shall be proportionately reduced, and (ii) in the event of a reduction in the number of outstanding shares shall be proportionately reduced, and the purchase price per share shall be proportionately increased.

(b) If the Company recapitalizes or otherwise changes its capital structure, thereafter upon any exercise or satisfaction, as applicable, of an Award theretofore granted the Holder shall be

-12-

entitled to (or entitled to purchase, if applicable) under such Award, in lieu of the number of shares of Stock then covered by such Award, the number and class of shares of stock and securities to which the Holder would have been entitled pursuant to the terms of the recapitalization if, immediately prior to such recapitalization, the Holder had been the holder of record of the number of shares of Stock then covered by such Award.

(c) In the event of a Change of Control, all outstanding Awards shall immediately vest and become exercisable or satisfiable, as applicable. The Committee, in its discretion, may determine that upon the occurrence of a Change of Control, each Award other than an Option outstanding hereunder shall terminate within a specified number of days after notice to the Holder, and such Holder shall receive, with respect to each share of Stock subject to such Award, cash in an amount equal to the excess, if any, of the Change of Control Value. Further, in the event of a Change of Control, the Committee, in its discretion shall act to effect one or more of the following alternatives with respect to outstanding Options, which may vary among individual Holders and which may vary among Options held by any individual Holder: (i) determine a limited period of time on or before a specified date (before or after such Change of Control) after which specified date all unexercised Options and all rights of Holders thereunder shall terminate, (2) require the mandatory surrender to the Company by selected Holders of some or all of the outstanding Options held by such Holders (irrespective of whether such Options are then exercisable under the provisions of the Plan) as of a date, before or after such Change of Control, specified by the Committee, in which event the Committee shall thereupon cancel such Options and the Company shall pay to each Holder an amount of cash per share equal to the excess, if any, of the Change of Control Value of the shares subject to such Option over the exercise price(s) under such Options for such shares, (3) make such adjustments to Options then outstanding as the Committee deems appropriate to reflect such Change of Control (provided, however, that the Committee may determine in its sole discretion that no adjustment is necessary to Options then outstanding) or (4) provide that thereafter upon any exercise of an Option theretofore granted the Holder shall be entitled to purchase under such Option, in lieu of the number of shares of Stock then covered by such Option the number and class of shares of stock or other securities or property (including, without limitation, cash) to which the Holder would have been entitled pursuant to the terms of the agreement of merger, consolidation or sale of assets and dissolution if, immediately prior to such merger, consolidation or sale of assets and dissolution the Holder has been the holder of record of the number of shares of Stock then covered by such Option. The provisions contained in this paragraph shall be inapplicable to an Award granted within six (6) months before the occurrence of a Change of Control if the Holder of such Award is subject to the reporting requirements of Section 16(a) of the 1934 Act. The provisions contained in this paragraph shall not terminate any rights of the Holder to further payments pursuant to any other agreement with the Company following a Change of Control.

-13-

(d) In the event of changes in the outstanding Stock by reason of recapitalization, reorganizations, mergers, consolidations, combinations, exchanges or other relevant changes in capitalization occurring after the date of the grant of any Award and not otherwise provided for by this Paragraph XII, any outstanding Awards and any agreements evidencing such Awards shall be subject to adjustment by the Committee at its discretion as to the number and price of shares of Stock or other consideration subject to such Awards. In the event of any such change in the outstanding Stock, the aggregate number of shares available under the Plan may be appropriately adjusted by the Committee, whose determination shall be conclusive.

(e) The existence of the Plan and the Awards granted hereunder shall not affect in any way the right or power of the Board or the shareholders of the Company to make or authorize any adjustment, recapitalization, reorganization or other change in the Company's capital structure or its business, any merger or consolidation of the Company, any issue of debt or equity securities ahead of or affecting Stock or the rights thereof, the dissolution or liquidation of the Company or any sale, lease, exchange or other disposition of all or any part of its assets or business or any other corporate act or proceeding.

(f) Any adjustment provided for in Subparagraphs (a), (b), (c) or (d) above shall be subject to any required shareholder action.

(g) Except as hereinbefore expressly provided, the issuance by the Company of shares of stock of any class or securities convertible into shares of stock of any class, for cash, property, labor or services, upon direct sale, upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares of obligations of the Company convertible into such shares or other securities, and in any case whether or not for fair value, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number of shares of Stock subject to Awards theretofore granted or the purchase price per share, if applicable.

XIII. AMENDMENT AND TERMINATION OF THE PLAN

The Board in its discretion may terminate the Plan at any time with respect to any shares for which Awards have not theretofore been granted. The Board shall have the right to alter or amend the Plan or any part thereof from time to time; provided that no change in any Award theretofore granted may be made which would impair the rights of the Holder without the consent of the Holder (unless such change is required in order to cause the benefits under the Plan to qualify as performance-based compensation within the meaning of section 162(m) of the Code and applicable interpretive authority thereunder), and provided, further, that the Board may not, without approval of the shareholders, amend the Plan:

-14-

(a) to increase the maximum number of shares which may be issued on exercise or surrender of an Award, except as provided in Paragraph XII;

(b) to change the Option price;

(c) to change the employees, directors or other individuals eligible to receive Awards or materially increase the benefits accruing to employees under the Plan;

(d) to extend the maximum period during which Awards may be granted under the Plan;

(e) to modify materially the requirements as to eligibility for participation in the Plan; or

(f) to decrease any authority granted to the Committee hereunder in contravention of Rule 16b-3.

XIV. MISCELLANEOUS

(a) NO RIGHT TO AN AWARD. Neither the adoption of the Plan by the Company nor any action of the Board or the Committee shall be deemed to give an employee, director or any other individual any right to be granted an Award to purchase Stock, a right to a Stock Appreciation Right, a Restricted Stock Award, a Performance Award or a Phantom Stock Award or any of the rights hereunder except as may be evidenced by an Award or by an Option Agreement, Stock Appreciation Rights Agreement, Restricted Stock Agreement, Performance Award Agreement or Phantom Stock Award Agreement on behalf of the Company, and then only to the extent and on the terms and conditions expressly set forth therein. The Plan shall be unfunded. The Company shall not be required to establish any special or separate fund or to make any other segregation of funds or assets to assure the payment of any Award.

(b) NO EMPLOYMENT RIGHTS CONFERRED. Nothing contained in the Plan shall
(i) confer upon any employee, director or any other individual any right with respect to continuation of employment with the Company or any subsidiary or (ii) interfere in any way with the right of the Company or any subsidiary to terminate his or her employment at any time.

(c) OTHER LAWS; WITHHOLDING. The Company shall not be obligated to issue any Stock pursuant to any Award granted under the Plan at any time when the shares covered by such Award have not been registered under the Securities Act of 1933, as amended, and such other state and federal laws, rules or regulations as the Company or the Committee deems applicable and, in the opinion of legal counsel for the Company, there is no exemption from the registration requirements

-15-

of such laws, rules or regulations available for the issuance and sale of such shares. No fractional shares of Stock shall be delivered, nor shall any cash in lieu of fractional shares be paid. The Company shall have the right to deduct in connection with all Awards any taxes required by law to be withheld and to require any payments required to enable it to satisfy its withholding obligations.

(d) NO RESTRICTION ON CORPORATE ACTION. Nothing contained in the Plan shall be construed to prevent the Company or any subsidiary from taking any corporate action which is deemed by the Company or such subsidiary to be appropriate or in its best interest, whether or not such action would have an adverse effect on the Plan or any Award made under the Plan. No employee, director, beneficiary or other person shall have any claim against the Company or any subsidiary as a result of any such action.

(e) RESTRICTIONS ON TRANSFER. An Award shall not be transferable otherwise than by will or the laws of descent and distribution or pursuant to a "qualified domestic relations order" as defined by the Code or Title I of the Employee Retirement Income Security Act of 1974, as amended, or the rules thereunder, and shall be exercisable during the Holder's lifetime only by such Holder or the Holder's guardian or legal representative.

(f) RULE 16B-3. It is intended that the Plan and any grant of an Award made to a person subject to Section 16 of the 1934 Act meet all of the requirements of Rule 16b-3. If any provision of the Plan or any such Award would disqualify the Plan or such Award under, or would otherwise not comply with, Rule 16b-3, such provision or Award shall be construed or deemed amended to conform to Rule 16b-3.

(g) SECTION 162(M). If the Plan is subject to 162(m) of the Code, it is intended that the Plan comply fully with and meet all the requirements of
Section 162(m) of the Code so that Options and Stock Appreciation Rights granted hereunder and, if determined by the Committee, Restricted Stock Awards, shall constitute "performance-based" compensation within the meaning of such section. If any provision of the Plan would disqualify the Plan or would not otherwise permit the Plan to comply with Section 162(m) as so intended, such provision shall be construed or deemed amended to conform to the requirements or provisions of Section 162(m); provided that no such construction or amendment shall have an adverse effect on the economic value to a Holder of any Award previously granted hereunder.

(h) GOVERNING LAW. This Plan shall be construed in accordance with the laws of the State of Texas.

This Agreement provides for (i) the merger of New Bank with and into Union with Union as the survivor (the "Initial Merger"), all pursuant to this Agreement and a Plan of Merger by and between New Bank and Union, a copy of which is attached hereto as Exhibit "A" and all of the terms of which are incorporated by reference for all purposes and, immediately thereafter, (ii) the merger of New Bank with and into FPB with FPB as the survivor (the "Final Merger"), all pursuant to this Agreement and a Plan of Merger by and between Union and FPB, a copy of which is attached hereto as Exhibit "B" and all of the terms of which are incorporated by reference for all purposes. The Initial Merger and the Final Merger shall sometimes be referred to collectively as the "Mergers." In connection with the Initial Merger, Bancshares will acquire all of the issued and outstanding shares of common stock, $10.00 par value, of Union ("Union Common Stock") for an aggregate consideration as set forth in this Agreement.

All rights of creditors and other obligees and all liens on property of either the First Surviving Bank or FPB shall be preserved unimpaired subsequent to the Mergers.

Section 1.9. MERGER CONSIDERATION. Shares of Union Common Stock issued and outstanding immediately prior to the Effective Time, other than Dissenting Shares (as defined in Section 1.11 of the Agreement), shall, by virtue of the Initial Merger and without any action on the part of the holder thereof, be converted into and represent the right to receive aggregate consideration in the form of cash equal to $17,600,000.00, as subject to adjustment pursuant to this Agreement (the "Merger Consideration"), or approximately $251.43 for each of the 70,000 shares of Union Common Stock issued and outstanding at the Effective Time, payable to the holders of record such shares of Union Common Stock, without interest thereon, upon surrender of the certificate representing such shares.

Section 1.10. ADJUSTMENT TO MERGER CONSIDERATION. In the event the Closing
(as defined in Section 6.1) does not occur on or before one hundred fifty (150)
calendar days from the date this Agreement is executed and Union's failure to fulfill any material obligation under this Agreement has not been the cause of, or resulted in, the failure of the Mergers to become effective on or before such date, then the Merger Consideration will increase by $2,612.00 per day for each day between the end of such one hundred fifty (150) day period and the Closing Date (as defined in Section 6.2).

Section 1.11. DISSENTING SHARES. Each share of Union Common Stock issued and outstanding immediately prior to the Effective Time, the holder of which has not voted in favor of the Mergers and who has delivered a written demand for payment of the fair value of such shares within the time and in the manner provided in Article 5.12 of the Texas Business Corporation Act ("TBCA"), is referred to herein as a "Dissenting Share." Dissenting Shares shall not be converted into or represent the right to receive the Merger Consideration pursuant to Section 1.9 of this Agreement unless and until such holder shall have failed to perfect or shall have effectively withdrawn or lost his right to appraisal and payment under the TBCA. If any such holder shall have so failed to perfect or shall have effectively withdrawn or lost such right, such holder's Dissenting Shares shall thereupon be deemed to have been converted into and to have become exchangeable for, at the Effective Time, the right to receive the Merger Consideration without any interest thereon. As set forth in Section 8.5 of this Agreement, if the holders of more than 10% of the Union Common Stock shall have exercised their dissenters' rights, Bancshares shall have no obligation to consummate the Mergers.

Section 1.12. EXCHANGE OF SHARES.

(a) Bancshares shall deposit or cause to be deposited in trust with FPB (the "Exchange Agent") prior to the Effective Time cash in an aggregate amount sufficient to make the cash payments pursuant to Section 1.9 hereof and to make the appropriate cash payments, if any, to holders of Dissenting Shares pursuant to Section 1.11 hereof (such amounts being hereinafter referred to as the "Exchange Fund"). The Exchange Agent shall promptly make the payments of the Merger Consideration out of the Exchange Fund upon surrender of such shares. Payments to holders of Dissenting Shares shall be made as required by the TBCA. The Exchange Fund shall not be used for any other purpose, except as provided in this Agreement.

(b) At least 20 days prior to the Effective Time, the Exchange Agent shall mail to each record holder of an outstanding certificate or certificates which represent shares of Union Common Stock (the "Certificates"), a form letter of transmittal which will specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent and contain instructions for use in effecting the surrender of the Certificates for payment therefor. At and after the Closing (as defined herein) and upon surrender to the Exchange Agent of a Certificate, together with such letter of transmittal duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor the amount of cash provided in Section 1.9 hereof in the manner described herein, and such Certificate shall forthwith be canceled. Payment will be made at Closing for shares of Union Common Stock if Certificates and a properly completed letter of transmittal with respect to such shares are received by the Exchange Agent at least five days prior to Closing. Payment will be made for all other shares of Union Common Stock within five days after the Exchange Agent's receipt of the Certificates and

-5-

a properly completed letter of transmittal. No interest will be paid or accrued on the cash payable upon surrender of the Certificates. If payment of cash is to be made to a person other than the person in whose name the Certificate surrendered is registered, it shall be a condition of payment that the Certificate so surrendered shall be properly endorsed or otherwise in proper form for transfer and that the person requesting such payment shall pay any transfer or other taxes required by reason of the payment to a person other than the registered holder of the Certificate surrendered or established to the satisfaction of Bancshares that such tax has been paid or is not applicable. Until surrendered in accordance with the provisions of this Section 1.12, each Certificate (other than Certificates representing Dissenting Shares) shall represent for all purposes the right to receive the Merger Consideration without any interest thereon.

(c) After the Effective Time, the stock transfer ledger of Union shall be closed and there shall be no transfers on the stock transfer books of Union of the shares of Union Common Stock which were outstanding immediately prior to such time of filing. If, after the Effective Time, Certificates are presented to Bancshares, they shall be promptly presented to the Exchange Agent and exchanged as provided in this Section 1.12.

(d) Any portion of the Exchange Fund (including the proceeds of any investments thereof) that remains unclaimed by the shareholders of Union for six months after the Effective Time shall be paid to Bancshares, and the holders of shares of Union Common Stock not theretofore presented to the Exchange Agent shall look to Bancshares only, and not the Exchange Agent, for the payment of any Merger Consideration in respect of such shares.

Section 1.13. RATIFICATION BY SHAREHOLDERS. This Agreement shall be submitted to the shareholders of Union in accordance with applicable provisions of law and the respective Articles of Association and Bylaws of Union. Union and Bancshares shall proceed expeditiously and cooperate fully in the procurement of any other consents and approvals and the taking of any other actions in satisfaction of all other requirements prescribed by law or otherwise necessary for consummation of the Mergers on the terms herein provided, including, without limitation, the preparation and submission of all necessary filings, requests for waivers and certificates with the Board of Governors of the Federal Reserve System ("Federal Reserve Board"), the Federal Deposit Insurance Corporation ("FDIC") and the Banking Department.

Section 2.15. ALLOWANCE FOR CREDIT LOSSES. The allowance for credit losses of Union has been calculated in accordance with generally accepted accounting principles as applied to banking institutions and in accordance with all applicable rules and regulations. To the knowledge of Union, the allowance for credit losses shown on Union's Call Report of March 31, 1998 is substantially adequate in all material respects to provide for all losses, net of recoveries relating to loans previously charged off, on loans outstanding as of March 31, 1998. At the Effective Time, no material facts relevant to the adequacy of the allowance for credit losses as of that date shall have been withheld from Bancshares. Except as disclosed in writing to Bancshares by Union on or before the date of the Agreement, there are no loans of Union that have been classified by bank examiners on Union's most recent examination report as "Other Assets Especially Mentioned," "Substandard," "Doubtful" or "Loss."

Section 2.16. EMPLOYMENT RELATIONS. The relations of Union with its employees are satisfactory, and Union has not received any notice of any controversies with, or organizational efforts or other pending actions by, representatives of its employees. Union has materially complied with all laws relating to the employment of labor with respect to its employees, including any provisions thereof relating to wages, hours, collective bargaining and the payment of workman's compensation insurance and social security and similar taxes, and, except as disclosed in Schedule 2.16 hereto, no person has asserted that Union is liable for any arrearages of wages, workman's compensation insurance premiums or any taxes or penalties for failure to comply with any of the foregoing.

Section 2.17. ERISA. The employee pension benefits plans and welfare benefit plans (referred to collectively herein as the "Plans") in effect at Union (all of which are included in Schedule 2.10 hereto) have all been operated in all material respects in compliance with ERISA since ERISA became applicable with respect thereto. None of the Plans nor any of their respective related trusts have been terminated (except the termination of any Plan which is in compliance with the requirements of ERISA and which will not result in any additional liability to Union), and there has been no "reportable event," as that term is defined in Section 4043 of ERISA, required to be reported since the effective date of ERISA which has not been reported, and none of such Plans nor their respective related trusts have incurred any "accumulated funding deficiency," as such term is defined in Section 302 of ERISA (whether or not waived), since the effective date of ERISA. The Plans are the only employee pension benefit plans covering employees of Union. Union will not have any material liabilities with respect to employee pension benefits, whether vested or unvested as of the Closing, for any of its employees other than under the Plans, and as of the date hereof the actuarial present value of Plan assets of each Plan is not less (and as of

-13-

the Closing of the Merger such present value will not be less) than the present value of all benefits payable or to be payable thereunder.

Section 2.18. DEFERRED COMPENSATION ARRANGEMENTS. The schedule attached as Schedule 2.18 contains a full description of all deferred compensation arrangements of Union, if any, including the terms under which the cash value of any life insurance purchased in connection with any such arrangement can be realized.

Section 2.19. LIST OF LOANS. Schedule 2.19 to this Agreement sets forth a true and complete list, as of March 31, 1998, of all loans (individually, a "Loan" and collectively, the "Loans") of Union, showing for each such Loan the outstanding principal balance due, before reduction for any discount. All currently outstanding Loans, including any current extensions of any Loan, were solicited, originated and currently exist in material compliance with all applicable requirements of federal and state law and regulations promulgated thereunder. To the knowledge of Union, the Loans are adequately documented and each note evidencing a Loan or credit agreement or security instrument related to a Loan constitutes a valid and binding obligation of the obligor thereunder, enforceable in accordance with the terms thereof, except where the failure thereof, individually or in the aggregate, would not have a material adverse effect on the condition (financial or otherwise), operations or prospects of Union. There are no oral modifications or amendments or additional agreements related to the Loans that are not reflected in Union's records, and no claim of defense as to the enforcement of any Loan has been asserted, and Union is not aware of any acts or omissions that would give rise to any claim or right of rescission, set off, counterclaim or defense, except where such claim would not have, either individually or in the aggregate, a material adverse effect on the condition (financial or otherwise), operations or prospects of Union.

Section 2.20. ABSENCE OF CHANGES. Since December 31, 1997, except as disclosed in Schedule 2.20 to this Agreement, there has not been any material adverse change in the financial condition, business or operations of Union; provided, however, that a material adverse change will not include a change with respect to, or effect on, Union resulting from a change in law, rule, regulations or GAAP or from any other matter affecting federally-insured depository institutions generally (including without limitation, their holding companies), including, without limitation, changes in general economic conditions and changes in prevailing interest or deposit rates; provided, any such change does not impact Union more adversely than other similarly situated financial institution. Since December 31, 1997, the business of Union has been conducted only in the ordinary course consistent with prior practices.

Union has a rating of "satisfactory" as of its most recent CRA compliance examination and knows of no reason why it would not receive a rating of "satisfactory" or better pursuant to its next CRA compliance examination or why the FDIC or any other governmental entity may seek to restrain, delay or prohibit the transactions contemplated hereby as a result of any act or omission of Union under the CRA.

Section 2.24. FAIR HOUSING ACT, HOME MORTGAGE DISCLOSURE ACT AND EQUAL CREDIT OPPORTUNITY ACT. Union is in material compliance with the Fair Housing Act (42 U.S.C. ss. 3601 ET SEQ.), the Home Mortgage Disclosure Act (12 U.S.C. ss. 2801 ET SEQ. and the Equal Credit Opportunity Act (15 U.S.C. ss. 1691 ET SEQ.) and all regulations promulgated thereunder.

Bancshares shall have fifteen days from the receipt of such notice to cure the alleged breach or inaccuracy, subject to the approval of Union (which approval shall not be unreasonably delayed or withheld).

(c) This Agreement may be terminated any time prior to the Effective Time by action of the Board of Directors of Bancshares if (i) Union shall fail to comply in

-25-

any material respect with any of its covenants or agreements contained in this Agreement, or if any of the representations or warranties of Union contained herein shall be inaccurate in any material respect, (ii) there shall have been any change after December 31, 1997, in the assets, properties, business or financial condition of Union which individually or in the aggregate have materially and adversely affected the financial condition, results of operation or business of Union, or (iii) the Board of Directors of Bancshares reasonably concludes, after consulting with counsel, that Bancshares will be unable to obtain any regulatory approval required in order to consummate the Mergers or any such approval is accompanied by terms or conditions unacceptable to Bancshares; provided, however, that a Federal Reserve Board requirement of a 5% leverage ratio, 6% Tier 1 capital to risk weighted assets ratio and 10% total capital to risk weighted assets ratio will not be deemed an unacceptable condition to Bancshares. In the event the Board of Directors of Bancshares desires to terminate this Agreement because of an alleged breach, inaccuracy or change as provided in (i) or (ii) above, the Board of Directors must notify Union in writing of its intent to terminate stating the cause therefor. Union shall have fifteen days from the receipt of such notice to cure the alleged breach, inaccuracy or change, subject to the approval of Bancshares (which approval shall not be unreasonably delayed or withheld).

(d) This Agreement may be terminated at any time prior to the Effective Time with the mutual written consent of Bancshares and Union and the approval of such action by their respective Boards of Directors.

(e) The execution and delivery of the Agreement and the consummation of the transactions contemplated thereby will not, to the best knowledge of counsel to Union, violate any provision of, or constitute a default under, any law, or any order, writ, injunction or decree of any court or other governmental agency, or any material contract, agreement or instrument to which Union is a party or by which it is bound or constitute an event which with the lapse of time or action by a third party could result in any default under any of the foregoing or result in the creation of any lien, charge or encumbrance upon the assets or properties of Union or upon the Union Common Stock.

Such opinion shall also cover such other matters incident to the transactions contemplated by the Agreement as Bancshares may reasonably request.

-56-
