                               PROSPECTUS SUMMARY
 
     The following summary does not purport to be complete, and is qualified in
its entirety by reference to the more detailed information and financial
statements (including the notes thereto) appearing elsewhere in this Prospectus.
Unless otherwise indicated, all share and per share information has been
adjusted to give effect to a 30 for 1 common stock split effected in the form of
a stock dividend issued to shareholders of record as of July 17, 1997. Unless
otherwise indicated, all information in this Prospectus assumes that the
Underwriters' over-allotment option is not exercised.
 
                                  THE COMPANY
 
     Prime Bancshares, Inc. (the "Company") is a bank holding company
headquartered in Houston, Texas. The Company derives substantially all of its
revenue and income from the operation of its wholly-owned bank subsidiary, Prime
Bank (the "Bank"), a Texas state bank with 19 full-service banking locations, 11
of which are located in the greater Houston metropolitan area. The Bank also has
six offices located in southeast Texas, one office (and two loan production
offices) located in San Antonio and one office located in Brenham. The Bank was
chartered in 1958. The Company was formed as a holding company for the Bank in
1984. The Company has made a profit in each year of its existence, and the
Company has had six consecutive years of increased net earnings. As of June 30,
1997, the Company had assets of $948.0 million, gross loans of $383.7 million,
total deposits of $878.7 million and total shareholders' equity of $65.3
million. Based on total assets as of June 30, 1997, the Company is the second
largest independent bank holding company headquartered in the Houston
metropolitan area.
 
     In 1988, the Company began to expand beyond its Channelview, Texas origins
and diversify its market area. A severe downturn in the Texas economy in the mid
to late 1980s caused a record number of bank and savings and loan failures,
which made deposits available for assumption through competitive bid processes.
The Company's strong capital base and historical profitability enabled it to
successfully bid for and acquire the deposits and certain assets of seven failed
financial institutions from 1988 to 1991. In 1994, the Company acquired nine new
locations (five of which were subsequently sold) through the acquisition of
deposits and certain assets related to branches of a large federal savings bank.
In 1997, the Company acquired deposits and certain assets related to three
commercial bank branches and acquired by merger Houston-based First Northwestern
Bank, N.A. In addition to adding market diversity, these acquisitions allowed
the Company to enhance its core deposit base and increase its total assets from
$81.2 million at December 31, 1987 to $948.0 million at June 30, 1997.
 
     The Company's business continues to reflect the Company's successful
community banking origins by providing a broad line of financial products and
services to small and medium-sized businesses and consumers. The Company
believes that its "super community" brand of banking, which allows for flexible,
responsive decision making at each branch in its network and focuses on
long-standing relationships with its customers and personalized service, is an
important factor in the success and growth of the Company.
 
     While the Company will continue to seek opportunities to expand its deposit
franchise, its strategic focus has shifted toward increasing its loan to deposit
ratio and further enhancing its profitability. The Company has expanded its
lending activities to include products which provide growth and profitability
such as (i) mortgage loans and indirect loans and (ii) increased commercial
loans. Each of the following lines of business was started several years ago and
has developed into a fast growing and profitable component of the Company's
operations:
 
     - Mortgage Banking. The Company uses its existing branch network to offer a
       complete line of single family residential mortgage products. The Company
       generally retains mortgage loans with shorter terms or variable rates and
       sells into the secondary market longer term fixed rate loans. During the
       six months ended June 30, 1997, the Company originated $20.0 million of
       mortgage loans.
 
     - Indirect Lending. In 1993, the Company initiated a program of purchasing
       indirect loans, which are installment loans primarily originated by
       automobile dealers for the purpose of financing consumer purchases. The
       Company purchases almost exclusively "A"-rated loans from a select list
       of local auto dealers and others after performing its own analysis of the
       loan package. The Company's total amount
 
                                        3
<PAGE>   4
 
of indirect loans at June 30, 1997 was $96.8 million. The Company's delinquency
ratio with respect to indirect loans for the six months ended June 30, 1997 was
 .69%.
 
     - Commercial Banking. In 1993, the Company established a separate
       commercial lending unit as an outgrowth of the Company's historical
       practice of making loans to small and medium-sized businesses from its
       various locations. The unit is staffed with experienced commercial
       lenders who generate commercial loans primarily in the greater Houston
       and San Antonio markets. The commercial loan customers generally have
       between $5.0 and $50.0 million in annual sales and the average loan is
       approximately $300,000.
 
     The Company's overall business strategy is to (i) continue to service its
small to medium-sized owner-operated businesses and consumer customers by
providing individualized, responsive, quality service through its supercommunity
banking network, (ii) continue to increase its loan to deposit ratio and thereby
enrich its earning asset mix, and (iii) augment its existing market share by
looking for additional expansion opportunities in growth areas, particularly in
the Houston and San Antonio markets.

                                  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.
 
EXPOSURE TO LOCAL ECONOMIC CONDITIONS
 
     The Company's success is dependent to a significant extent upon general
economic conditions in Texas and 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 1980's, 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
non-energy related industries. 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
Texas and the 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
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, governmental policies
such as the creation of a tax deduction for individual retirement accounts can
increase savings and 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 -- 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
non-financial 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 local office decision-making; by establishing long-term
customer relationships and
 
                                        7
<PAGE>   8
 
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 nonfinancial 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 and operations 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
"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."
 
RESTRICTIONS ON ABILITY TO PAY DIVIDENDS
 
     While the Company has paid cash dividends on the Common Stock since 1990,
there is no assurance that the Company will pay dividends on the Common Stock 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 Common Stock and
other factors deemed relevant by the Company's Board of Directors. 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. As of June 30, 1997, an aggregate of approximately $21.3 million
was available for payment of dividends by the Bank to the Company under
applicable restrictions, without regulatory approval. See "Supervision and
Regulation -- The Bank."
 
     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
 
                                        8
<PAGE>   9
 
to preserve certain capital adequacy requirements. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Capital
Resources" and "Supervision and Regulation."
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company and the Bank are dependent on certain key personnel including
Fredric M. Saunders and E. J. Guzzo, each of whom is considered to be important
to the success of the Company. The unexpected loss of such personnel or other
members of senior management could have an adverse effect on the Company and the
Bank. The Company has not, however, entered into employment agreements with or
obtained any "key man" insurance for any of the personnel discussed above.
 
POSSIBLE ANTI-TAKEOVER 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 and that any action
required or permitted to be taken by the Company's shareholders may not be
effected by consent in writing, (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 recently enacted 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."
 
CONCENTRATION OF OWNERSHIP
 
     After the consummation of the Offering, the executive officers and
directors of the Company will beneficially own 51.76% of the outstanding shares
of Common Stock, and approximately 48.72% 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 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 63.26% in their investment, in that the
tangible book value of the Company after the Offering will be approximately
$6.43 compared with an assumed initial public offering price of $17.50 per
share. Options to purchase a total of 600,000 shares of Common Stock were
outstanding under the Company's stock option plans at June 30, 1997, of which
174,000 were exercisable at prices ranging from $0.83 to $2.67 per share. If the
shares subject to such options under the Company's stock option plans were
included in the foregoing calculations, further dilution to new shareholders
would be incurred. See "Dilution."
    
 
NO PRIOR TRADING MARKET
 
   
     Prior to the Offering, there has been no public market for the shares of
Common Stock. The Common Stock has been approved for quotation on the
Nasdaq/National Market under the symbol "PBTX." The
    
 
                                        9
<PAGE>   10
 
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 was
determined by negotiations between the Company and the Representatives and does
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 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 of the Underwriters 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 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 was 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. See
"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.
    
 
RESTRICTIONS ON FUTURE SALE OF SHARES
 
     The Company will have 9,239,020 shares of Common Stock outstanding after
the Offering. The Company, its executive officers and directors and certain
shareholders (who collectively will own 51.76% of the outstanding shares of
Common Stock 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 170 shareholders of record, and all of such shares will be
freely tradable in accordance with Rule 144(k) under the Securities Act. In
addition, all of the shares of Common Stock sold in the Offering 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
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 must
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.

                                  THE COMPANY
 
GENERAL
 
     The Company was incorporated as a business corporation under the laws of
the State of Texas in 1984 to serve as a holding company for the Bank, which was
chartered in 1958. Fredric M. Saunders, the Company's Chairman of the Board,
joined the Bank in 1962 as President. Based on total assets at June 30, 1997,
the Company ranks as the second largest independent bank holding company
headquartered in the Houston metropolitan area. The Company's headquarters are
located at 12200 Northwest Freeway, Houston, Texas 77092, and its telephone
number is (713) 209-6000.
 
     From its inception until 1988, the Bank primarily served individuals and
small businesses in and around its original principal location in the town of
Channelview, located in the northeastern part of the Houston metropolitan area.
In the mid to late 1980s, the record number of bank and savings and loan
failures caused by a severe downturn in the Texas economy presented the Company
with an opportunity to expand its branch network in the greater Houston area and
expand geographically to other parts of the state, as well as enhance its core
deposit base. From 1988 to 1991, the Company acquired the deposits and certain
assets of seven failed financial institutions, five of which were located in the
Houston area, with the others located in Brenham and San Antonio. In 1994, the
Company acquired the deposits and certain assets of nine branch locations from
First Heights Bank fsb, five of which were subsequently sold, with the Company
retaining branches in Orange, Beaumont, Nederland and Houston. In early 1997,
the Company purchased from a commercial bank the deposits and certain assets
related to three additional branches in Beaumont, Port Arthur and Port Neches,
and acquired by merger First Northwestern Bank, N.A. in Houston. Since the
beginning of 1996, the Company has also established a new full-service branch in
the Houston Galleria area and two loan production offices in San Antonio. As a
result of this expansion activity, the Company has grown from an organization
with two banking locations and assets of $81.2 million at December 31, 1987 to
its current 19 full-service bank locations and assets of $948.0 million at June
30, 1997.
 
     The Company has developed a super community banking network, with most of
its offices located either in separate communities or portions of urban areas
that function as distinct communities. Lending and investment activities are
funded from a strong core deposit base consisting of approximately 98,000
deposit accounts from approximately 55,000 households. Each of the Company's
offices has a manager with the authority and flexibility to make pricing
decisions within overall ranges developed by the Company as a form of quality
control. The Company believes that its responsiveness to local customers and
ability to adjust deposit rates and price loans at each location gives it a
distinct competitive advantage. Adequate staffing is provided at each location
to ensure that customers needs are well addressed, and employees are committed
to quality service and developing long-term customer relationships. The Company
provides economic incentives to its officers to develop additional business for
the Company and to cross sell additional products and services to existing
customers.
 
     The Company continues to look for additional expansion opportunities,
either through acquisitions of existing financial institutions or by
establishing de novo branches or loan production offices. The Company intends to
consider various strategic acquisitions of banks, banking assets or financial
service entities related to banking in those areas that management believes
would complement and help grow the Company's existing business. The Company is
particularly optimistic about the growth potential in the Houston and San
Antonio market areas and in 1997 acquired First Northwestern Bank, N.A. in
Houston and opened two loan production offices in San Antonio.
 
BUSINESS
 
     In connection with the geographic expansion, market diversification and
deposit acquisitions discussed above, over the past several years the Company
began to seek new lines of business to diversify its asset mix and further
enhance its profitability. While each new line of business reflects the
Company's efforts to enrich its asset mix, each of these lines of business is an
outgrowth of the community banking and small to medium-sized business lending
that the Company has performed so profitably over the years. Reflective of the
 
                                       11
<PAGE>   12
 
Company's conservative philosophy, each of these businesses has been developed
deliberately by the Company and is subject to various quality controls. The
Company's principal lines of business are the following:
 
          Community Banking. The Company has historically extended credit
     through its branch network to owner-operated small to medium-sized
     businesses and to consumers. The Company offers businesses a wide variety
     of lending products including term loans, lines of credit and fixed asset
     loans, including real estate and equipment financing. These loans, most of
     which are 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. As a general practice, the Company takes as
     collateral a lien on any available real estate, equipment or other assets
     and obtains the personal guaranty of the owner or owners of the business.
     Consumer loans made by the Company include automobile loans, recreational
     vehicle loans, boat loans, home improvement loans and personal loans (both
     collateralized and uncollateralized).
 
          Mortgage Banking. The Company uses its existing branch network to
     offer a complete line of single family residential mortgage products. The
     Company generally retains mortgage loans with shorter terms or variable
     rates and sells into the secondary market longer term fixed rate loans. As
     a result, the Company retains approximately half of the mortgage loans that
     it originates. The Company originates mortgage loans only in its market
     areas and services only the loans that it retains. The Company does not buy
     mortgage loans from other sources. The volume of mortgage loans originated
     by the Company has increased from $11.9 million in 1994 to a volume of
     $20.0 million in the first half of 1997.
 
          Indirect Lending. In 1993, the Company initiated a program of
     purchasing indirect loans, which are installment loans with typical
     maturities of three to five years originated primarily by automobile
     dealers for the purpose of financing consumer purchases and sold by the
     dealers to commercial banks and other sources of financing. The Company
     purchases almost exclusively "A"-rated loans primarily from a select list
     of local auto dealers and others after performing its own analysis of the
     loan package. The indirect loan program is staffed by 12 people and managed
     by an officer with over 20 years of experience in this area and a thorough
     knowledge of the reliability of various dealers. The Company also purchases
     some indirect boat and recreational vehicle loans. The program's
     delinquency ratios of 0.69% for the six months ended June 30, 1997 and .95%
     for the year ended December 31, 1996 compare favorably to the industry
     average. Similarly, the Company's net loan charge-off ratio of 0.30% at
     June 30, 1997 is well below the industry average for this type of lending.
     The Company's total amount of indirect loans at June 30, 1997 was $96.8
     million. The Company plans to maintain its current quality controls and
     grow the indirect loan program at a controlled pace. As a matter of
     operating philosophy, the Company is willing to forego the potentially
     higher yield represented by lower grade loans in exchange for the better
     credit quality of the "A"-rated loans.
 
          Commercial Banking. In 1994, the Company established a separate
     commercial lending unit as an outgrowth of the Company's historical
     business of making loans to small and medium-sized businesses from its
     various locations. The commercial lending unit is staffed with experienced
     commercial lenders who generate commercial loans through solicitations of
     potential customers primarily in the greater Houston and San Antonio
     markets. The commercial loan customers generally have between $5.0 million
     and $50.0 million in annual sales, and the average commercial loan is
     approximately $300,000. Most of these loans are secured by real estate and
     are backed by the personal guaranty of the owners of the business. The
     Company makes commercial loans to a wide variety of industries. The Company
     intends to expand this business by adding additional experienced commercial

COMPETITION
 
     The banking business is highly competitive, and the profitability of the
Company depends principally on 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
non-financial 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 local office decision-making; 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, 1997, the Company had 406 full-time employees, 82 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.
 
                                USE OF PROCEEDS
 
   
     The net proceeds to be received by the Company from the Offering (based
upon the initial public offering price of $17.50 per share), after deducting the
underwriting discount and estimated expenses, are estimated to be approximately
$6.3 million, or $7.5 million if the Underwriters' over-allotment option is
fully exercised. The Company intends to use all of such proceeds to redeem all
6,000,000 shares of its Series A 10% Non-Cumulative Preferred Stock ("Series A
Preferred Stock") immediately after completion of the Offering. Pursuant to its
terms, the Series A Preferred Stock will be redeemed for its $6.0 million
liquidation value on or before December 1, 1997. If such net proceeds are not
sufficient to redeem all of the outstanding shares of Series A Preferred Stock,
the Company will use internal funds to redeem the remainder of such shares. The
Company will not receive any of the proceeds from the sale of the shares of
Common Stock being sold by the Selling Shareholders in the Offering.
    
 
     The Series A Preferred Stock was issued in 1994 to provide additional
capital to support the growth resulting from the Company's acquisition of nine
branch locations owned by a large federal savings bank. The Company currently
has adequate capital and desires to eliminate the $600,000 annual dividend on
the Series A Preferred Stock. Officers and directors of the Company and their
affiliated interests own an aggregate of 1,729,000 shares of Series A Preferred
Stock and will receive $1,729,000 in connection with the redemption.
 
     Dividends on the shares of Series A Preferred Stock are payable quarterly
and are calculated based on the $1.00 per share par value of such shares.
Dividends on Series A Preferred Stock are not cumulative, and the Company is
prohibited from paying any cash dividends on its Common Stock unless the Company
also declares and pays a dividend with respect to the Series A Preferred Stock
for the quarter during which such dividend is to be declared and paid with
respect to the Common Stock. Each share of Series A Preferred Stock is entitled
to a liquidation preference of $1.00. The holders of Series A Preferred Stock
have no voting rights. The Series A Preferred Stock may be redeemed, in whole or
in part, at $1.00 per share together with all declared and unpaid dividends per
share.
 
     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 declared dividends on its Common Stock since
1990 and currently pays quarterly dividends aggregating $0.13 per share per
annum, there is no assurance that the Company will continue to pay dividends in
the future. The Company plans to pay a dividend on or about October 1, 1997 to
the holders of record of Common Stock as of September 15, 1997.
 
     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 -- 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 Common
Stock and other factors deemed relevant by the Company's Board of Directors. See
"Supervision and
 
                                       14
<PAGE>   15
 
Regulation" and "Description of Securities of the Company." As of June 30, 1997,
an aggregate of approximately $21.3 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 -- Capital Resources" and "Supervision and
Regulation."
 
                                    DILUTION
 
   
     As of June 30, 1997, the tangible book value of the Common Stock was $6.01
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 sale by the Company of 400,000
shares of Common Stock offered hereby (after deducting 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, 1997 would have been $6.43 per
share. This represents an immediate increase in net tangible book value of $0.42
per share to current shareholders and an immediate dilution of $11.07 per share
to new investors. The following table illustrates this per share dilution.

     The foregoing computations do not take into account the possible exercise
of outstanding stock options granted under the Company's stock option plans or
the possible issuance of up to an additional 325,397 shares of Common Stock to
new investors pursuant to the exercise of an option granted by the Company to
the Representatives solely to cover over-allotments, if any, in connection with
the Offering. See "Underwriting." Options to purchase a total of 600,000 shares
of Common Stock were outstanding under the Company's stock option plans at June
30, 1997, of which 174,000 were exercisable at prices ranging from $0.83 to
$2.67 per share. If the shares subject to such outstanding options under the
Company's stock option plans were included in the foregoing calculations,
further dilution to new shareholders would be incurred.

                 NATURE OF THE TRADING MARKET AND MARKET PRICES
 
     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. 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. See "Risk Factors -- No Prior Trading Market."
 
   
     The initial public offering price of the shares of Common Stock was
determined by negotiations between the Company and the Representatives and does
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 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 of the Underwriters 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 was 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. See
"Underwriting" for information relating to the method of determining the initial
public offering price. The shares of Common Stock have been approved for
quotation on the Nasdaq/National Market under the symbol "PBTX."

recurring adjustments) necessary to present fairly the financial position and
results of operations of the Company as of such dates and for such periods. The
results of operations for the six months ended June 30, 1997, are not
necessarily indicative of the results of operations that may be expected for the
year ended December 31, 1997, or for any future periods.

                 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 earnings. 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, 1997 AND 1996
 
OVERVIEW
 
     The six month period ended June 30, 1997 was marked by strong balance sheet
growth due to the Company's acquisition of approximately $99.2 million in
deposits related to three branch locations acquired from a commercial bank and
the acquisition of First Northwestern Bank, N.A. with approximately $60.5
million in deposits. The Company's earnings growth, however, was affected by the
non-recurring expenses (data processing conversion, severance benefits and other
items) related to those transactions.
 
     Net earnings available to common shareholders for the six months ended June
30, 1997 were $5.1 million, $283,000 or 5.8% more than net earnings for the six
months ended June 30, 1996. Net earnings per common share were $0.56 for the six
months ended June 30, 1997 and $0.53 for the six months ended June 30, 1996. The
increase in net earnings reflected higher net interest income, which was driven
by growth in interest-earning assets, including strong internal loan growth.
Earnings growth was reduced by higher operating expenses, which included
non-recurring expenses of $416,000 related to the acquisitions. Return on
average assets and return on average common equity were 1.22% and 18.44%,
respectively, for the six months ended June 30, 1997 compared to 1.37% and
18.70%, respectively, for the same time period in 1996. Excluding non-recurring
acquisition expenses, net earnings available to common shareholders would have
been $5.4 million for the six months ended June 30, 1997, resulting in an
adjusted return on average assets and return on average common equity of 1.28%
and 19.42%, respectively.
 
     Total assets at June 30, 1997 increased to $948.0 million from $765.4
million at June 30, 1996, an increase of $182.6 million or 23.9%. Deposits rose
to $878.7 million at June 30, 1997 from $700.4 million at June 30, 1996, an
increase of $178.4 million or 25.5%. Acquisitions accounted for approximately
$153.7 million of the growth in deposits and internal growth accounted for $24.7
million of such growth. Total shareholders' equity was $65.3 million at June 30,
1997, representing an increase of $6.9 million or 11.8% over total shareholders'
equity of $58.4 million at June 30, 1996.
 
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, 1997 was $17.3
million compared to $14.6 million for the six months ended June 30, 1996, an
increase of $2.7 million or 18.4%. Net interest income increased as a result of
higher interest-earning assets derived primarily from the acquisitions in the
first quarter of 1997 and loan growth. Average interest-earning assets increased
to $848.5 million for the six months ended June 30, 1997 from $716.7 million for
the six months ended June 30, 1996, an increase of $131.8 million or 18.4%.
Average loans increased to $354.7 million for the six months ended June 30, 1997
from $246.4 million for the six months ended June 30, 1996, an increase of
$108.3 million or 44.0%. Internal loan growth accounted for $77.4 million of
this increase, and acquisitions accounted for the remaining $30.9 million of the
increase. The increase in interest income was partially offset by higher expense
on interest-bearing deposits. Average
 
                                       20
<PAGE>   21
 
interest-bearing deposits increased to $701.4 million for the six months ended
June 30, 1997 from $584.2 million for the six months ended June 30, 1996, an
increase of $117.2 million or 20.1%. This growth was primarily attributable to
the first quarter 1997 acquisitions.
 
     The Company posted net interest margins of 4.12% and 4.11% and net interest
spreads of 3.39% and 3.35% for the periods ended June 30, 1997 and June 30,
1996, respectively. The slight increase in the net interest margin from the
first half of 1996 to the first half of 1997 reflects a 12 basis point increase
in the yield on average interest-earning assets and an 8 basis point increase in
the cost of interest-bearing liabilities. The yield on average interest-earning
assets increased to 7.57% for the six months ended June 30, 1997 from 7.45% for
the six months ended June 30, 1996. The increase in yield on average
interest-earning assets was due primarily to loan growth, but it was reduced by
the investment of a large portion of the acquired funds into lower-yielding
securities. The cost of interest-bearing liabilities increased to 4.18% for the
six months ended June 30, 1997 from 4.10% for the six months ended June 30,
1996. This increase was due mainly to the higher cost of the acquired funds.

     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. No tax
equivalent adjustments were made and all average balances are daily average
balances. Nonaccruing loans have been included in the tables as loans carrying a
zero yield.

  Provision for Loan Losses
 
     The provision for loan losses decreased slightly to $525,000 for the six
months ended June 30, 1997 from $596,000 for the same time period in 1996, a
decrease of $71,000 or 11.9%.
 
  Noninterest Income
 
     Noninterest income is an important source of revenue for financial
institutions in a deregulated environment. The Company's primary source of
noninterest income is service charges on deposit accounts and other banking
service related fees.
 
     Noninterest income for the six months ended June 30, 1997 was $4.3 million,
an increase of $184,000 or 4.5% from $4.1 million for the same period in 1996.

     Service charges on deposit accounts is 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 1997 as compared to the first six months of 1996 resulted mainly
from the acquisitions which occurred in the first quarter of 1997.

  Noninterest Expense
 
     In the six month period ended June 30, 1997, noninterest expenses increased
$2.5 million or 24.0% to $12.7 million from $10.2 million for the period ended
June 30, 1996. The increase reflected the additional expenses resulting from
acquisitions consummated in the first quarter of 1997. The Company anticipates
that cost savings from the consolidation of back office operations of the bank
acquired during the first quarter of 1997 will be fully realized in the third
quarter of 1997. The efficiency ratio, calculated by dividing total noninterest
expenses (excluding securities losses) by net interest income plus noninterest
income was 58.8% for the six months ended June 30, 1997 and 54.6% for the six
months ended June 30, 1996. The increase in the efficiency ratio was partially
due to non-recurring acquisition expenses of $416,000. Excluding the non-
recurring expenses, the Company's efficiency ratio in 1997 would have been
56.8%.

</TABLE>
 
     Employee compensation and benefit expense for the six months ended June 30,
1997 was $8.0 million, an increase of $1.6 million or 24.5% from $6.4 million in
the same period of 1996. The increase was principally due to additional staff
associated with the acquisitions closed in the first quarter, the new Galleria
branch which was opened in the last half of 1996, and additional loan staff
hired. Total full-time equivalent employees at June 30, 1997 increased to 434
from 376 at June 30, 1996.
 
     Non-staff expenses, including non-recurring acquisition expenses of
$375,000, increased to $4.7 million for the six month period ended June 30, 1997
from $3.8 million for the same period in 1996, an increase of $886,000 or 23.2%.
Excluding the non-recurring acquisition expenses, the increase was $511,000 or
13.4%. This increase was largely due to additional expenses associated with the
newly acquired locations. Included in regulatory assessments for the six months
ended June 30, 1997 is a refund of FDIC insurance premiums in the amount of
$169,000 resulting from insured deposit rate adjustments.
 
  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 expense. 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 1997
and 1996. During the six months ended June 30, 1997, income tax expense was $2.9
million compared to $2.7 million for the six months ended June 30, 1996.

  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 "-- Interest
Rate Sensitivity and Liquidity" below.
 
FINANCIAL CONDITION
 
  Loan Portfolio
 
     Loans, net of unearned interest, were $383.7 million at June 30, 1997, an
increase of $116.8 million or 43.7% from $267.0 million at June 30, 1996.
Acquisitions accounted for $40.2 million of this growth, while internally
generated loans accounted for $76.6 million of the increase.

     The primary lending focus of the Company is on small and medium-sized
business and consumer loans. The Company offers a variety of commercial lending
products including term loans, lines of credit and fixed asset loans, including
real estate and equipment financing. 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.
 
     Although its legal lending limit is substantially higher, the Company
generally does not make loans larger than $3.0 million. Loans up to $400,000 are
evaluated and acted upon by an officers' loan committee, which meets twice per
week. Loans above that amount must be approved by the Executive Loan Committee,
which meets weekly.
 
     Generally, the Company's commercial loans are underwritten in the Company's
primary market area 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 and obtains a personal
guaranty. 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 on which structures have already been
completed. Additionally, a portion of the Company's lending activity has
consisted of the origination of
 
                                       25
<PAGE>   26
 
single-family residential mortgage loans collateralized by owner-occupied
properties located in the Company's market areas. The Company offers a variety
of mortgage loan products which generally are amortized over five to 30 years.
 
     Loans collateralized by single-family residential real estate generally
have been originated in amounts of no more than 80% of appraised value or have
mortgage insurance. The Company requires mortgage title insurance and hazard
insurance in the amount of the loan. Of the mortgages originated, the Company
generally retains mortgage loans with short terms or variable rates and sells
longer term fixed-rate loans and loans that do not meet the Company's credit
underwriting standards. As a result, the Company retains approximately half of
the mortgage loans that it originates.
 
     The Company's commercial mortgage loans are secured by first liens on real
estate, typically have fixed interest rates and amortize over a 10 to 15 year
period with balloon payments due at the end of three to five years. 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 checks, 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. 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 automobile loans, recreational
vehicle loans, boat loans, home improvement loans, personal loans
(collateralized and uncollateralized) and deposit account collateralized loans.
The terms of these loans typically range from 12 to 84 months and vary based
upon the nature of collateral and size of loan.
 
     Approximately 64.2% of the Company's consumer loan portfolio as of June 30,
1997, was comprised of indirect loans (representing 25.2% of the Company's total
loan portfolio). These are installment loans, with typical maturities of three
to five years, which are originated mostly by automobile dealers for the purpose
of financing consumer automobile purchases and sold by automobile dealers to
commercial banks and other sources of financing. The Company also purchases some
indirect boat and recreational vehicle loans. The average yield on the Company's
indirect loan portfolio was 8.51% for the first six months of 1997.
 
     The Company's indirect loan programs are administered by a staff specially
trained in evaluating and servicing this particular type of loan. The Company
competes for these loans with a number of other financial and non-financial
institutions, including the captive financial services subsidiaries of
automobile manufacturers, on the basis of interest rate and quality of service.
 
     The Company generally receives credit applications on a daily basis from
one or more of the automobile dealerships and others from which it actively
purchases indirect loans. Upon receipt of a credit application, the Company
undertakes a credit analysis of the prospective purchaser, ordering credit
reports on the borrower which are analyzed by one of the officers specializing
in buying indirect loans. In making credit decisions, such officers evaluate,
among other things, the general credit quality of the applicant, the proposed
income to debt ratio, and residential and employment stability.
 
     The collection of overdue indirect loans is administered by a staff
specially trained for such purpose. Holders of loans that are 10 days past due
generally receive written notice of such delinquency. When any loan becomes 15
days past due, the collectors establish telephone contact with the borrower. If
the loan remains past due for 30 days, the Company generally sends a demand
letter requiring payment within 10 days before asserting its legal rights. The
Company's collection staff makes all reasonable efforts to work out credit
problems before the accounts are turned over to independent repossession agents.
Repossessed automobiles are sold as soon as possible through a number of means
in order to minimize any potential losses. The Company's ongoing experience with
indirect loan underwriting and collections has contributed to a relatively low
delinquency rate of 0.69% as of June 30, 1997.

  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. Although
nonperforming assets (nonaccrual loans, restructured loans and other real
estate) at June 30, 1997 increased to $1.3 million from $460,000 at June 30,
1996, this increase was primarily attributable to credits and other real estate
acquired in recent acquisitions. However, the Company's ratio of nonperforming
assets to loans and other real estate remained low at 0.33% at June 30, 1997
compared to 0.17% at June 30, 1996.
 
     The Company generally places a loan on nonaccrual status and ceases
accruing interest when loan payment performance is deemed unsatisfactory. All
loans past due 90 days, however, are placed on nonaccrual status, unless the
loan is both well-secured and in the process of collection. Cash payments
received while a loan is classified as nonaccrual are recorded as a reduction of
principal as long as doubt exists as to collection. The Company is sometimes
required to revise a loan's interest rate or repayment terms in a troubled debt
restructuring. The Company had no restructured loans at either June 30, 1997 or
June 30, 1996. The Company's internal loan review department evaluates
additional loans which are potential problem loans as to risk exposure in
determining the adequacy of the allowance for loan losses.
 
     The Company maintains on an ongoing basis updated appraisals on loans
secured by real estate, particularly those categorized as nonperforming loans
and potential problem loans. In instances where updated
 
                                       27
<PAGE>   28
 
appraisals reflect reduced collateral values, 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 loan losses. The
Company records other real estate at fair value at the time of acquisition, less
estimated costs to sell.
 
     The following table presents information regarding nonperforming assets at
June 30, 1997 and June 30, 1996:

     The Company would have recorded additional interest income of approximately
$16,000 in the first six months of 1997 on nonperforming loans if the loans had
been current in accordance with original terms. Interest income recorded on
nonperforming loans for the first six months of 1997 was approximately $13,000.
 
  Allowance for Loan Losses
 
     The allowance for loan losses is a reserve established through charges to
earnings in the form of a provision for loan losses. Management has established
an allowance for loan losses which it believes is adequate for estimated losses
in the Company's loan portfolio. Based on an evaluation of the loan portfolio,
management presents a quarterly review of the allowance for loan 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 loan 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. At June
30, 1997, the Company had $841,000 of such loans, excluding loans on nonaccrual,
which were primarily residential and commercial real estate loans.
 
     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. Although loans classified as substandard do not duplicate loans
classified as doubtful, both substandard and doubtful loans include some loans
that are delinquent at least 30 days or on nonaccrual status. 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 show warning elements
where the present status portrays one or more deficiencies that require
attention in the short term or where pertinent ratios of the loan account 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 as compared with those of a satisfactory
credit. The Company reviews these loans
 
                                       28
<PAGE>   29
 
to assist in assessing the adequacy of the allowance for loan losses. At June
30, 1997, the Company had $640,000 of such loans, which were primarily secured
by residential and commercial real estate.
 
     In order to determine the adequacy of the allowance for loan 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 loan losses to maintain the allowance for loan losses
at an adequate level determined by the foregoing methodology.
 
     For the six months ended June 30, 1997, net loan charge-offs totaled
$338,000 or 0.19% of average loans outstanding for the period, compared to
$183,000 in net loan charge-offs or 0.15% of average loans for the six months
ended June 30, 1996. During the six months ended June 30, 1997, the Company
recorded a provision for loan losses of $525,000 compared to $596,000 for the
six months ended June 30, 1996. At June 30, 1997, the allowance totaled $5.1
million, or 1.33% of total loans resulting in an allowance to nonperforming
loans of 858.99%.
 
     The following table presents, for the periods indicated, an analysis of the
allowance for loan losses and other related data:

     The Company believes that the allowance for loan losses at June 30, 1997 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, 1997.
 
  Securities
 
     The Company uses its securities portfolio primarily as a source of income
and secondarily as a source of liquidity. At June 30, 1997, investment
securities totaled $465.8 million, an increase of $15.9 million from $449.9
million at June 30, 1996. The increase was primarily attributable to the
investment of funds acquired in acquisitions. At June 30, 1997, investment
securities represented 49.1% of total assets compared to 58.8% of total assets
at June 30, 1996. The yield on the investment portfolio for the six months ended
June 30, 1997 was 6.52% compared to a yield of 6.53% for the six months ended
June 30, 1996.

     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. Included in the Company's mortgage-backed
securities at June 30, 1997 were $27.6 million in agency-issued collateral
mortgage obligations and $581,500 in privately-issued collateral mortgage
obligations.
 
     At June 30, 1997, 18.8% of the mortgage-backed securities held by the
Company had final maturities of more than 10 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, 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. Approximately $41.6 million of the Company's
mortgage-backed securities earn interest at floating rates and reprice within
one year, and accordingly are less susceptible to declines in value should
interest rates increase.
 
     In December of 1996, the Company purchased $30.4 million of mortgage-backed
securities classified as held-to-maturity. This transaction, which settled in
January of 1997, was the principal cause of the $30.6 million decline in other
liabilities from December 31, 1996 to June 30, 1997. See "Note M -- Supplemental
Statement of Cash Flow Information" to the Financial Statements.

     Effective January 1, 1994, the Company adopted Statement of Financial
Accounting Standards No. 115, Accounting for Certain Investments in Debt and

                                       31
<PAGE>   32
 
the Company is required to classify debt and equity securities into one of three
categories: held-to-maturity, trading or available-for-sale. At each reporting
date, the appropriateness of the classification is reassessed. Investments in
debt securities are classified as held-to-maturity and measured at amortized
cost in the financial statements only if management has the positive intent and
ability to hold those securities to maturity. Securities that are bought and
held principally for the purpose of selling them in the near term are classified
as trading and measured at fair value in the financial statements with
unrealized gains and losses included in earnings. Investments not classified as
either held to maturity or trading are classified as available-for-sale and
measured at fair value in the financial statements with unrealized gains and
losses reported, net of tax, in a separate component of shareholders' equity
until realized.
 
  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, 1997
were $838.3 million or 20.1% over average total deposits during the same period
in 1996. The Company's total deposits at June 30, 1997, were $878.7 million, up
$178.4 million or 25.5% over total deposits at June 30, 1996.
 
     The Company's lending and investing activities are funded principally by
deposits, approximately 50.3% of which are demand and savings deposits. Average
noninterest-bearing deposits at June 30, 1997 were $136.8 million as compared to
$113.5 million for the first six months of 1996, an increase of $23.4 million or
20.6%. Approximately 16.3% of average deposits for the six months ended June 30,
1997 were noninterest-bearing. The amount of deposits grew due to a combination
of new location acquisitions and the opening of a new branch in the Galleria
area of Houston.
 
     The daily average balances and weighted average rates paid on
interest-bearing deposits for the period ended June 30, 1997 are presented

  Interest Rate Sensitivity and Liquidity
 
     The Company's 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.
 
     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 adversely net interest income, while a positive GAP
would tend to result in an increase in net interest income. During a period of
falling interest rates, a negative GAP would tend to result in an increase in
net interest income, while a positive GAP would tend to affect net interest
income adversely.
 
     The following table sets forth an interest rate sensitivity analysis for
the Company at June 30, 1997:

     Shortcomings are inherent in GAP analysis since certain assets and
liabilities may not move proportionally as interest rates change. Consequently,
in addition to GAP analysis the Company uses a simulation model
 
                                       33
<PAGE>   34
 
and shock analysis to test the interest rate sensitivity of net interest income
and the balance sheet, respectively. Based on the Company's June 30, 1997
simulation analysis, the Company estimates that a 200 basis point rise or
decline in rates over the next twelve month period would have an impact of less
than 3.0% on its net interest income for the same period. The change is
relatively small, despite the Company's liability sensitive GAP position. This
results 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. The Company maintains an Investment Committee that reviews the
Company's interest rate risk position, generally on a monthly basis.
 
     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 been met primarily by financing activities, which consisted
mainly of growth in core deposits, supplemented by earnings through operating
activities. In the Company's investing activities, highly liquid securities have
provided much flexibility as demonstrated in meeting the cash demands of the
branch sale in 1995. Although access to purchased funds from correspondent banks
is available and has been utilized on occasion to take advantage of investment
opportunities, the Company does not generally rely on these external funding
sources.
 
  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.
 
     Bank regulatory authorities in the United States have issued risk-based
capital standards by which all bank holding companies and banks are evaluated in
terms of capital adequacy. The risk-based capital standards issued by the
Federal Reserve Board apply to the Company. These guidelines relate a financial
institution's capital to the risk profile of its assets. The risk-based capital
standards require all financial institutions 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.
 
                                       34
<PAGE>   35
 
     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." The Bank is classified
"well capitalized" for purposes of the FDIC's prompt corrective action
regulations. See "Supervision and Regulation -- The Company" and "-- The Bank."
 
     Shareholders' equity increased from $58.4 million at June 30, 1996 to $65.3
million at June 30, 1997, an increase of $6.9 million or 11.8%. This increase
was primarily the result of net income of $9.5 million, less the payment of
common stock and preferred stock dividends of $1.2 million and $700,000,
respectively, and a decrease in net unrealized gains on available for sale
securities net of taxes of $456,000. The Company had outstanding at June 30,
1997 $6.0 million in liquidation value of Series A Preferred Stock and $1.0
million in liquidation value of Series B Preferred Stock, both of which qualify
as Tier 1 capital.

              FOR THE YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994
 
OVERVIEW
 
     The Company engaged in several transactions in 1994, 1995 and 1996 which
had a significant impact on the Company's performance in each of those years. In
October 1994, the Company acquired $338.9 million in deposits in connection with
its acquisition of nine branch locations owned by a large federal savings bank.
In the last half of 1995, the Company sold five of those branches (including
$77.4 million in deposits) and recorded a $2.4 million gain on the branch sales.
In 1996, the Company paid a one-time FDIC assessment of $1.8 million with
respect to the Company's deposits insured by the Savings Association Insurance
Fund ("SAIF") of the FDIC.
 
     Net earnings available to common shareholders were $8.5 million, $8.4
million and $7.6 million for the years ended December 31, 1996, 1995 and 1994,
respectively, and net earnings per common share were $0.92, $0.89 and $0.79 for
these same periods. Earnings growth from 1995 to 1996 resulted principally from
strong internal loan growth and a higher net interest margin. The increase in
earnings from 1994 to 1995 was due primarily to higher interest-earning assets,
resulting mainly from the 1994 branch acquisitions, and the gain on the sale of
the branches. The Company posted returns on average assets of 1.21%, 1.09% and
1.32% and returns on average common equity of 16.13%, 18.98% and 19.49% for the
years ended 1996, 1995 and 1994, respectively. Without the one-time FDIC
assessment in 1996, the Company's return on average assets and return on average
common equity, respectively, would have been 1.36% and 18.36%.
 
     Total assets at December 31, 1996, 1995 and 1994 were $801.5 million,
$758.3 million and $863.5 million, respectively. Total deposits at December 31,
1996, 1995 and 1994 were $695.2 million, $694.2 million and $813.8 million,
respectively. The Company retained a major portion of the deposits acquired
during 1994 while repricing maturing deposits into a lower rate structure. The
result was an improved net interest margin and steady deposit levels from 1995
to 1996. Loans were $311.3 million at December 31, 1996, an increase of $81.1
million or 35.2% from $230.2 million at the end of 1995. Loans were $197.9
million at year end 1994. Common shareholders' equity was $55.0 million, $51.3
million and $40.8 million at December 31, 1996, 1995 and 1994, respectively.
Changes in common shareholders' equity reflect fluctuations in the net
unrealized appreciation on available-for-sale securities, net of tax in the
amounts of a $3.2 million decrease in 1996 and a $4.7 million increase in 1995.
 
RESULTS OF OPERATIONS
 
  Net Interest Income
 
     1996 versus 1995. Net interest income totaled $30.1 million in 1996
compared to $28.2 million in 1995, an increase of $1.9 million or 6.8%. The
increase resulted mainly from lower interest expense on deposits and higher
interest income on loans. Interest expense decreased $3.4 million and was only
partially offset by a decline of $1.5 million in total interest income. This
resulted in net interest margins of 4.20% and 3.62% and net interest spreads of
3.44% and 2.98% for 1996 and 1995, respectively.
 
     The decline in interest expense from 1995 to 1996 was due primarily to
lower average interest-bearing deposits of $580.8 million in 1996 versus $659.0
million in 1995. The decline in average interest-bearing deposits, which
included the sale of branches in the last half of 1995, was comprised of $61.2
million or 78.3% in certificates of deposit, and the remainder was primarily in
savings accounts. Accordingly, the cost of average interest-bearing deposits
declined to 4.08% in 1996 from 4.12% in 1995. Interest income on loans increased
to $24.7 million in 1996 from $19.4 million in 1995. The increase was driven by
growth in the average loan portfolio of $54.2 million or 25.4% and an increase
in the yield on average loans to 9.22% in 1996 from 9.07% in 1995. Meanwhile,
the average securities portfolio declined $101.0 million, and its yield rose 15
basis points.
 
     1995 versus 1994. Net interest income increased $4.6 million in 1995 from
$23.6 million in 1994, primarily due to growth in interest income of $17.2
million. This increase was partially offset by an increase in interest expense
of $12.6 million. This resulted in net interest margins of 3.62% and 4.25% and
net interest spreads of 2.98% and 3.65% for 1995 and 1994, respectively.
 
                                       36
<PAGE>   37
 
     The increase in interest income was driven by growth in average
interest-earning assets of $223.1 million or 40.1% due mostly to the branch
acquisitions which occurred in late 1994. Growth in interest-earning assets
included average loan growth of $71.4 million or 50.3% and growth in average
securities of $139.3 million or 34.7%. Also, the yield on average
interest-earning assets increased 24 basis points from 1994 to 1995. The yield
on average loans declined to 9.07% in 1995 from 9.73% in 1994, but the yield on
average securities increased to 6.38% in 1995 from 5.92% in 1994. The decline in
the loan yield was due primarily to higher amortization in 1994 of the purchase
discount associated with loans purchased in a previous acquisition. The increase
in the securities yield resulted mainly from higher-yielding U.S. Treasury
securities. The increase in interest expense was due both to an increase in
average interest-bearing deposits of $205.9 million and to an increase in their
cost of 91 basis points. Both occurrences resulted primarily from the branch
acquisitions.

     The following table presents for the periods indicated the total dollar
amount of 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. No tax equivalent adjustments were made and
all average balances are yearly average balances. Nonaccruing loans have been
included in the tables as loans carrying a zero yield.

     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
be segregated have been allocated.

  Provision for Loan Losses
 
     The 1996 provision for loan losses declined slightly to $1.2 million from
$1.5 million in 1995, a decrease of $264,000 or 17.5%. The reduced provision in
1996 reflected improved asset quality as net charge-offs of loans continued at
relatively low levels totaling $470,000 or 0.18% of average loans, compared to
$491,000 or 0.23% of average loans in 1995. The provision for the year 1995
increased by $930,000 or 160.3% from the year ended 1994 due to loan growth and
a higher amount of charged-off loans in 1995 compared to 1994.
 
  Noninterest Income
 
     Noninterest income for the year ended December 31, 1996 was $8.3 million,
down from $10.3 million in 1995, and noninterest income in 1994 was $7.2
million. The year ended December 31, 1995 included a gain of $2.4 million on the
sale of five branches. Excluding this gain, noninterest income was $399,000
greater in 1996 than in 1995 and $685,000 greater in 1995 than in 1994. This
results in annual percentage increases of 5.1% and 9.5% for 1996 and 1995,
respectively. The following table presents for the periods indicated the major
categories of noninterest income:

     After excluding the gain from the sale of branches in 1995, the increase in
noninterest income from 1995 to 1996 resulted mainly from service charges on
deposit accounts. Service charges on deposit accounts increased $213,000 from
1995 to 1996 in conjunction with new product pricing which was implemented in
the first quarter of 1996. Additionally, the Company's increased emphasis on fee
based services resulted in greater income from retail services, mortgage
banking, and investment services. The increase from 1994 to 1995 was due mainly
to deposit growth from the 1994 branch acquisition, increased investment
services income and implementation of a securities lending program.
 
  Noninterest Expense
 
     For the years ended 1996, 1995 and 1994, noninterest expenses totaled $23.1
million, $23.1 million and $18.3 million, respectively. The slight decline in
1996 reflects several major offsetting factors: a $1.8 million FDIC assessment
on SAIF deposits which was offset by lower overall fees on FDIC insured deposits
and the effect of the sale of five branches in the last half of 1995. The
increase in 1995 of $4.8 million or 26.0% was primarily due to higher employee
compensation and benefits, reflecting the additional staff acquired in the late
1994 branch acquisition. The Company's efficiency ratios were 60.09% in 1996,
59.99% in 1995 and 59.07% in 1994. The efficiency ratio was constant over this
period, reflecting the Company's continued efforts to control operating
expenses. The following table presents for the periods indicated the major
categories of noninterest expense:

     Employee compensation and benefit expense for the year ended December 31,
1996 was $13.1 million, an increase of $183,000 or 1.4% from $12.9 million for
1995. Employee compensation and benefit expense for the year 1995 was up $3.1
million or 31.2% from 1994. The increase in 1995 was primarily due to increased
staff acquired in the branch acquisitions during late 1994. The increase in 1996
resulted mainly from additions to the loan staff but was mitigated by the branch
sales which occurred in the last half of 1995. Total full-time equivalent
employees at December 31, 1996, 1995 and 1994 were 386, 372 and 385,
respectively.
 
     Non-staff expenses were $10.0 million in 1996, a decline of $237,000 from
$10.2 million in 1995. The decline in 1996 occurred in spite of the $1.8 million
special assessment from the FDIC on SAIF deposits and was due to reduced expense
levels resulting from the branch sales, which occurred in the last half of 1995,
as well as lower FDIC fees on all deposits. The 1995 level increased $1.7
million or 19.9% from 1994 non-staff expenses of $8.5 million. The increase in
1995 reflected the effect of the branch acquisitions in late 1994.
 
  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
 
                                       40
<PAGE>   41
 
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 from federal
securities. The income tax component of the Texas franchise tax was zero in
1996, 1995 and 1994. In 1996, income tax expense was $4.8 million, approximately
the same as 1995. The 1995 amount was $787,000 higher than the 1994 amount of
$4.0 million, or 19.4%. The effective tax rates in 1996, 1995 and 1994,
respectively, were 34.03%, 34.41% and 34.03%.
 
FINANCIAL CONDITION
 
  Loan Portfolio
 
     Total loans increased by $81.1 million or 35.2% to $311.3 million at
December 31, 1996, from $230.2 million at December 31, 1995. During 1995, total
loans increased by $32.3 million or 16.3% from $197.9 million at December 31,
1994. The growth in loans reflected the improving local economy and the
Company's investment in loan production capacity.
 
     At December 31, 1996, total loans represented 44.8% of deposits and 38.8%
of total assets. Total loans as a percentage of deposits were 33.2% at December

     Effective January 1, 1995, the Company adopted SFAS No. 114, Accounting for
Creditors for Impairment of a Loan, as amended by SFAS No. 118, Accounting by
Creditors for Impairment of a Loan-
 
                                       41

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 measurement 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 No. 114 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, have resulted in strong asset quality. Nonperforming assets at December
31, 1996 were $288,000 compared to $1.6 million at December 31, 1995 and $1.5
million at December 31, 1994. This resulted in ratios of nonperforming assets to
total loans plus other real estate of 0.09%, 0.71% and 0.73% for the years ended
1996, 1995 and 1994, respectively.
 
     The following table presents information regarding nonperforming assets at

     At December 31, 1996, securities totaled $440.6 million, a decrease of
$33.3 million from $473.9 million at December 31, 1995. The decrease occurred
primarily in U.S. Government securities and reflected the Company's use of funds
from maturities to fund loans. During 1995, securities decreased $131.2 million
from $605.1 million at December 31, 1994, reflecting the decline in deposits
which resulted from the branch sales during 1995 and the repricing of deposits
acquired in 1994 into a lower rate structure. During 1995, the Company
transferred from held-to-maturity to available-for-sale accounts securities with
an amortized cost of $339.8 million and net unrealized gains of $6.2 million at
the date of transfer. The transfer was made in light of pending branch sales in
order to maintain the Company's interest rate risk position.

  Deposits
 
     Average total deposits during 1996 decreased to $695.7 million from $772.8
million in 1995, a decrease of $77.1 million or 10.0%. The decrease resulted
primarily from the sales of five branch locations with approximately $77.4
million in deposits and the continued repricing of maturing deposits acquired in
the branch acquisitions of 1994 into a lower rate structure. Approximately 79.3%
of the decline occurred in certificates of deposit which lowered the cost of
deposits to 3.40% in 1996 from 3.51% in 1995 and increased

the ratio of average demand deposits to average total deposits to 32.5% in 1996
from 29.3% in 1995. Average deposits in 1995 rose to $772.8 million from $550.6
million in 1994, an increase of $222.2 million or 40.4%. The increase resulted
primarily from the branch acquisitions which occurred in late 1994. The
Company's ratios of average noninterest-bearing demand deposits to average total
deposits for years ended December 31, 1996, 1995 and 1994 were 16.5%, 14.7% and
17.7%, respectively.

  Capital Resources
 
     Shareholders' equity increased to $62.0 million at December 31, 1996 from
$58.3 million at December 31, 1995, an increase of $3.6 million or 6.2%. This
increase was primarily the result of net income of $9.2 million offset by a
decline in the net unrealized appreciation on available-for-sale securities of
$3.2 million and dividends paid of $1.9 million. During 1995, shareholders'
equity increased by $11.5 million or 24.5%, from $46.8 million at December 31,
1994. In addition to net income, the increase reflected a change of $4.7 million
in unrealized appreciation on available-for-sale securities.

STOCK OPTION PLANS
 
     The Company has outstanding options to purchase 600,000 shares of Common
Stock issued pursuant to incentive stock option plans approved by shareholders
in 1984 (the "1984 Plan") and 1993 (the "1993 Plan.") Under the 1984 Plan, 10%
of the options granted vest immediately following the date of grant and an
additional 10% each year thereafter. Options granted under the 1984 Plan
generally must be exercised within 10 years following the date of grant or no
later than three months after termination of the optionee's employment, if
earlier. Under the 1993 Plan, 20% of the options granted vest at the end of the
first year following the date of grant and an additional 20% each year
thereafter. Options granted under the 1993 Plan generally must be exercised
within 10 years following the date of grant or no later than three months after
termination of the optionee's employment, if earlier.
 
     The Company's Board of Directors and shareholders approved a new stock
option plan in 1997 (the "1997 Plan") which authorizes the issuance of up to
1,000,000 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 1997 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 1997 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 1997 Plan.
 
     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-
 
                                       51
<PAGE>   52
 
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 in 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.
 
OPTION GRANTS DURING 1996

BENEFIT PLAN
 
     The Company has established a contributory profit sharing plan pursuant to
Internal Revenue Code Section 401(k) covering substantially all employees (the
"Plan"). The Bank is the Plan administrator and has hired Smith Barney, Inc. to
serve as the trustee and investment advisor. Each year the Company determines,
in its discretion, the amount of matching contributions. The Company has elected
to match 25% of employee contributions not to exceed 6% of the employee's annual
compensation. As an additional incentive to employees, the Plan does not have a
vesting schedule, and thus all employees are 100% vested from the moment of
contribution. Total Plan expenses charged to the Company's operations for 1996,
1995 and 1994 were approximately $97,000, $96,000 and $68,000 respectively. The
Company has budgeted $108,000 for 1997 contributions.
 
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 at least a 5% interest, are customers of the Company. During 1996
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,
 
                                       52
<PAGE>   53
 
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, 1997, all of such loans aggregated $2.6 million, which was approximately
4.3% 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.
 
     The Company leases space for its Houston Atrium 10 branch pursuant to a
lease agreement with Atrium 10 Tower, L.P., in which Stuart D. Saunders is an
11.5% limited partner and Meredith Saunders Mason, the daughter of Fredric M.
Saunders, is also an 11.5% limited partner. The lease agreement was entered into
on an arm's length basis on substantially the same terms as those prevailing at
the time for comparable transactions with unrelated persons.
 
                             PRINCIPAL SHAREHOLDERS
 
     The following table sets forth certain information regarding the beneficial
ownership of the Company's Common Stock as of August 31, 1997, and as adjusted

                           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
 
                                       55
<PAGE>   56
 
banking practices). The Federal Reserve 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, 1997, the Company's ratio of Tier 1 capital to total
risk-weighted assets was 13.74% and its ratio of total capital to total
risk-weighted assets was 14.92%. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- 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, 1997, the Company's leverage ratio
was 6.31%.
 
     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.
 
                                       56
<PAGE>   57
 
     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 company 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") and the SAIF of the FDIC. The
Bank is not a member of the Federal Reserve System; therefore, the Bank is
subject to supervision and regulation by the FDIC and the Texas Banking
Department. Such supervision and regulation 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, 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.
 
                                       57
<PAGE>   58
 
     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 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
 
                                       58
<PAGE>   59
 
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% and a
ratio of total capital to total risk-weighted assets of 8%. The capital
categories have the same definitions for the Bank as for the Company. As of June
30, 1997, the Bank's ratio of Tier 1 capital to total risk-weighted assets was
13.66% and its ratio of total capital to total risk-weighted assets was 14.85%.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operation of the Company -- Capital Resources."
 
     The FDIC's leverage guidelines require state banks to maintain Tier 1
capital of no less than 5% of average total assets, except in the case of
certain highly rated banks for which the requirement is 3% 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, 1997, the
Bank's ratio of Tier 1 capital to average total assets (leverage ratio) was
6.27%. See "Management's Discussion and Analysis of Financial Condition and
Results of Operation of the Company -- 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% or higher; a Tier 1 risk based capital ratio of 6% or
higher; a leverage ratio of 5% 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% or higher; a Tier 1 risk based capital ratio of 4% or
higher; a leverage ratio of 4% or higher (3% or higher if the bank was rated a
CAMEL 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 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
 
                                       59
<PAGE>   60
 
concern the institution poses to the regulators. In addition, the FDIC can
impose special assessments in certain instances.
 
     After the one-time SAIF assessment in 1996, the assessment rate disparity
between BIF and SAIF members was eliminated. The current range of BIF and SAIF
assessments is between 0% and .27% of deposits. Institutions which qualify for
the 0% assessment category such as the Bank do, however, still have to pay the
$1,000 minimum semi-annual assessment required by federal statute.
 
     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. The Texas
Banking Department also has broad enforcement powers over the Bank, including
the power to impose orders, remove officers and directors, impose fines and
appoint supervisors and conservators.
 
     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
 
                                       60
<PAGE>   61
 
an application to acquire ownership or control of shares or assets of a bank or
to merge with any other bank holding company. An unsatisfactory record can
substantially delay or block the transaction.
 
     Consumer Laws and Regulations. In addition to the laws and regulations
discussed herein, the Bank is also subject to certain consumer laws and
regulations that are designed to protect consumers in transactions with banks.
While the list set forth herein is not exhaustive, these laws and regulations
include the Truth in Lending Act, the Truth in Savings Act, the Electronic Funds
Transfer Act, the Expedited Funds Availability Act, the Equal Credit Opportunity
Act, and the Fair Housing Act, among others. These laws and regulations mandate
certain disclosure requirements and regulate the manner in which financial
institutions must deal with customers when taking deposits or making loans to
such customers. The Bank must comply with the applicable provisions of these
consumer protection laws and regulations as part of their ongoing customer
relations.
 
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) 15,000,000
shares of preferred stock, $1.00 per share par value ("Preferred Stock"),
issuable in series, 6,000,000 shares of which are designated Series A Preferred
Stock, all of which are issued and outstanding and 1,250,000 shares of which are
designated Series B 10% Non-Cumulative Preferred Stock ("Series B Preferred
Stock"), 1,000,000 of which shares are outstanding and (ii) 50,000,000 shares of
Common Stock, $.25 per share par value, of which 12,010,980 shares were issued
and 8,839,020 shares were outstanding as of June 30, 1997. 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. As of June
30, 1997, an additional 600,000 shares of Common Stock were issuable upon
exercise of the Company's outstanding employee and director incentive stock
options.
 
     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 15,000,000 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 Company has issued and outstanding 6,000,000 shares of Series A
Preferred Stock and 1,000,000 shares of Series B Preferred Stock (the Series A
Preferred Stock and Series B Preferred Stock being sometimes collectively
referred to as the "Outstanding Preferred Stock"). Dividends on both Series A
and B Preferred Stock aggregate 10% of par value per annum, payable quarterly.
Dividends with respect to the Outstanding Preferred Stock are not cumulative.
Accordingly, the Board of Directors of the Company has no
 
                                       62
<PAGE>   63
 
obligation to declare and pay dividends with respect to the Outstanding
Preferred Stock except as expressly provided in the Articles of Incorporation or
as provided by law. Pursuant to the terms of each of the Series A Preferred
Stock and the Series B Preferred Stock, however, the Company may not declare or
pay a dividend with respect to the Common Stock unless the Company also declares
and pays a dividend with respect to the Series A and B Preferred Stock for the
quarter during which such dividend is to be declared or paid with respect to the
Common Stock. The Outstanding Preferred Stock has no voting rights. The Series A
Preferred Stock is redeemable at any time at the option of the Company at the
$1.00 liquidation value of the shares plus all declared but unpaid dividends
thereon to the date fixed for redemption. The Series B Preferred Stock is
redeemable at any time after January 1, 1998 at the option of the Company at the
$1.00 liquidation value of the shares plus all declared but unpaid dividends
thereon, except that the per share redemption price (exclusive of declared and
unpaid dividends) for shares redeemed after January 1, 1998 but on or before
January 1, 1999 is $1.02, and the per share redemption price for shares redeemed
after January 1, 1999 but on or before January 1, 2000 is $1.01. In the event of
the liquidation, dissolution or winding up of the affairs of the Company, prior
to any distribution or payment to the holders of Common Stock or any other class
of stock of the Company ranking junior to the Outstanding Preferred Stock,
holders of the Outstanding Preferred Stock shall be entitled to be paid in full
the $1.00 liquidation value of the shares plus all declared but unpaid dividends
thereon to the date of payment. The Company plans to redeem the Series A
Preferred Stock after the closing of the Offering.
 
     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.
 
     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.
 
                                       63
<PAGE>   64
 
     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. However, the Board of Directors may not declare or pay cash dividends
on Common Stock, and no Common Stock may be purchased by the Company, unless
full dividends have been declared and paid on outstanding Preferred Stock for
the current dividend period and, with respect to any outstanding cumulative
preferred stock, all past dividend periods. See "Risk Factors -- 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 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 adopts 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.
 
                                       64
<PAGE>   65
 
     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 an annual 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 an annual 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 an annual meeting to be timely, such
notice must be received by the Company not less than 70 days prior to the first
anniversary of the previous year's annual meeting (or if the date of the annual
meeting is advanced by more than 20 days not later than the tenth day after
public announcement of the date of such meeting is first made). Notwithstanding
the foregoing, in the event that the number of directors to be elected is
increased and there is no public announcement naming all of the nominees for
director or specifying the size of the increased Board made by the Company at
least 80 days prior to the first anniversary of the preceding year's annual
meeting, a shareholder's notice will be timely, but only with respect to
nominees for any new positions created by such increase, if it is received by
the Company not later than the 10th day after such public announcement is first
made by the Company. The Bylaws further provide that, for notice of a
shareholder nomination to be made at a special meeting at which directors are to
be elected to be timely, such notice must be received by the Company not later
than the tenth day after public announcement of the date of such meeting is
first made.
 
     Under the Shareholder Notice Procedure, 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, the class and
number of shares of stock of the Company owned by such shareholder, information
regarding the proposed nominee that would be required under the federal
securities laws to be included in a proxy statement soliciting proxies for the
proposed nominee and, with respect to business other than a nomination, a brief
description of the business the shareholder proposes to bring before the
meeting, the reasons for conducting such business at such meeting and any
material interest of such shareholder in the business so proposed.
 
     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.
 
                                       65
<PAGE>   66
 
     Reduced Shareholder Vote Required for Certain Actions. The Company's
Articles of Incorporation provide that, notwithstanding any provision of the
Texas Business Corporation Act 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. 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.
 
     Amendment of Bylaws. The Company's Articles of Incorporation and 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.
 
                                  UNDERWRITING
 
     Subject to the terms and conditions of the Purchase Agreement among the

     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 of the Underwriters
that the Underwriters propose to offer 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 $0.74 per
share. The Underwriters may allow, and such dealers may re-allow, a concession
not in excess of $0.10 per share to certain other dealers. After the initial
public offering, the offering price and other selling terms may be changed by
the Representatives of the Underwriters.
    
 
     Pursuant to the Purchase Agreement, the Company and certain of the Selling
Shareholders have granted to the Underwriters an option, exercisable not later
than 30 days after the date of this Prospectus, to purchase up to 325,397
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, each Underwriter 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 and
each such Selling Shareholder granting such option 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 of the Underwriters, except that the Company may issue shares of
Common Stock upon the exercise of currently outstanding options. See "Risk
Factors -- Restrictions on Future Sale of Shares."
 
     The Representatives of the Underwriters have advised the Company that the
Underwriters do not intend to confirm sales to any account over which they
exercise discretionary authority.
 
     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 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 was
determined by negotiations between the Company and the Representatives of the
Underwriters. 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 of the Underwriters 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 was given to the general status of the securities
market, the
    
 
                                       67
<PAGE>   68
 
market conditions for new issues of securities and the demand for securities of
comparable companies at the time the Offering was made.
 
   
     The Common Stock has been approved for quotation on the Nasdaq/National
Market.

     The validity of the shares of Common Stock to be issued by the Company will

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
The Board of Directors and Shareholders
Prime Bancshares, Inc.
 
     We have audited the accompanying consolidated balance sheets of Prime
Bancshares, Inc. and Subsidiaries as of December 31, 1996 and 1995, and the
related consolidated statements of earnings, shareholders' equity and cash flows
for each of the three years in the period ended December 31, 1996. 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, the financial statements referred to above present fairly,
in all material respects, the financial position of Prime Bancshares, Inc. and
Subsidiaries as of December 31, 1996 and 1995, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1996 in conformity with generally accepted accounting principles.
 
     Effective January 1, 1994, Prime Bancshares, Inc. and Subsidiaries adopted
Statement of Accounting Standards No. 115, Accounting for Certain Investments in
Debt and Equity Securities.

NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     A summary of the significant accounting policies applied in the preparation
of the accompanying financial statements follow.
 
1. GENERAL
 
     The Bank operates nineteen branches in Southeast and Central Texas. The
Bank's primary sources of revenue are derived from investing in various United
States Treasury and Agency securities and granting loans primarily to customers
in Southeast and Central Texas. Although the Bank has a diversified loan
portfolio, a substantial portion of its debtors' ability to honor their
contracts is dependent on the economies in those areas.
 
2. PRINCIPLES OF CONSOLIDATION AND INVESTMENT IN SUBSIDIARIES
 
     The consolidated financial statements include the accounts of the Parent
and its wholly-owned subsidiaries, IBID, Inc. (IBID) and Prime Bank (the Bank)
(collectively referred to as the Company). All significant intercompany
transactions and balances have been eliminated in the consolidated report of the
Company.
 
3. CASH AND CASH EQUIVALENTS
 
     The Company considers all highly liquid debt instruments purchased with a
maturity of three months or less to be cash equivalents.
 
4. SECURITIES
 
     Effective January 1, 1994, the Bank adopted Statement of Financial
Accounting Standards (SFAS) No. 115, Accounting for Certain Investments in Debt
and Equity Securities (Statement 115). At the date of purchase, the Bank is
required to classify debt and equity securities into one of three categories:
held-to-maturity, trading or available-for-sale. At each reporting date, the
appropriateness of the classification is reassessed. Investments in debt
securities are classified as held-to-maturity and measured at amortized cost in
the financial statements only if management has the positive intent and ability
to hold those securities to maturity. Securities that are bought and held
principally for the purpose of selling them in the near term are classified as
trading and measured at fair value in the financial statements with unrealized
gains and losses included in earnings. Investments not classified as either
held-to-maturity or trading are classified as available-for-sale and measured at
fair value in the financial statements with unrealized gains and losses
reported, net of tax, in a separate component of shareholders' equity until
realized.
 
     Gains and losses on the sale of securities are determined using the
specific-identification method.
 
     Declines in the fair value of individual held-to-maturity and
available-for-sale securities below their carrying value 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.
 
     Premiums and discounts are recognized in interest income using the interest
method over the period to maturity.
 
     Government notes and mortgage-backed securities for which the Bank has the
positive intent and ability to hold to maturity are reported at cost, adjusted
for premiums and discounts that are recognized in interest income using the
interest method over the period to maturity.

NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
5. LOANS
 
     Loans are reported at the principal amount outstanding, net of charge-offs,
unearned discounts, purchase discounts and an allowance for loan losses.
Unearned discounts on installment loans are recognized using a method which
approximates a level yield over the term of the loans. Interest on other loans
is calculated using the simple interest method on the daily balance of the
principal amount outstanding.
 
     Effective January 1, 1995, the Company has adopted SFAS No. 114, Accounting
for Creditors for Impairment of a Loan, as amended by SFAS No. 118. Under SFAS
114, as amended, a loan is identified as impaired when it is probable that
interest and principal will not be collected according to the contractual terms
of the loan agreement. The accrual of interest on impaired loans is discontinued
when, in management's opinion, the borrower may be unable to meet payments as
they become due. All loans past due 90 days are placed on nonaccrual status
unless the loan is both well-secured and in the process of collection. When
interest accrual is discontinued, all unpaid accrued interest is reversed.
Interest income is subsequently recognized only to the extent cash payments are
received. Loans are not again placed on accrual status until payments are
brought current and, in management's judgment, the loan will continue to pay as
agreed.
 
6. ALLOWANCE FOR LOAN LOSSES
 
     The allowance for loan losses is established through a provision for credit
losses charged to expense. Loans are charged against the allowance for loan
losses when management believes that collectibility of the principal is
unlikely.
 
     The allowance is an amount that management believes will be adequate to
absorb losses inherent in existing loans and commitments to extend credit, based
on evaluations of the collectibility and prior loss experience of loans and
commitments to extend credit. The evaluations take into consideration such
factors as changes in the nature and volume of the portfolio, overall portfolio
quality, loan concentrations, specific problem loans and current and anticipated
economic conditions that may affect the borrower's ability to pay.
 
7. BANK PREMISES AND EQUIPMENT
 
     Premises and equipment are stated at cost, less accumulated depreciation.
Depreciation is provided on the straight-line basis over the estimated useful
life of each type of asset.
 
8. OTHER REAL ESTATE
 
     Real estate acquired is recorded at fair value at the date of foreclosure
or acquisition, 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. Operating expenses of such
properties, net of related income, and gains and losses on their disposition are
included in other expenses.
 
9. INCOME TAXES
 
     The Company files a consolidated Federal income tax return. By agreement
with the Parent, the Bank records a provision or benefit for Federal income
taxes on the same basis as if it filed a separate Federal income tax return. The
asset and liability method of accounting is used for income taxes where deferred
tax assets and liabilities are recognized for the future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases. When management
determines that it is more likely than not that a deferred tax asset will not be
realized, a valuation

                             (DOLLARS IN THOUSANDS)
 
NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
allowance must be established. Deferred tax assets and liabilities are measured
using enacted tax rates expected to apply to taxable income in the years in
which those temporary differences are expected to be recovered or settled. The
effect on deferred tax assets and liabilities of a change in tax rates is
recognized in income in the period that includes the enactment date.
 
10. EARNINGS PER COMMON AND COMMON EQUIVALENT SHARE
 
     Earnings per common and common equivalent share is calculated by dividing
net income available for common shareholders by the weighted average number of
common shares and common share equivalents. Stock options are regarded as common
share equivalents and are therefore considered in earnings per share
calculations, if dilutive. Options granted within one year of the initial public
offering (IPO) have been treated as outstanding for all periods as a component
of weighted average common share equivalents. The number of common share
equivalents is determined using the treasury stock method.
 
11. OFF-BALANCE SHEET FINANCIAL INSTRUMENTS
 
     In the ordinary course of business, the Bank enters into off-balance-sheet
financial instruments consisting of commitments to extend credit, commercial
letters of credit and standby letters of credit. Such financial instruments are
recorded in the financial statements when they are funded or related fees are
incurred or received.
 
12. USE OF ESTIMATES
 
     In preparing the financial statements in conformity with generally accepted
accounting principles, management is required to make estimates and assumptions
that affect the reported amounts of assets and liabilities and the disclosure of
contingent assets and liabilities at the date of the financial statements and
revenues and expenses during the reporting period. Actual results could differ
from those estimates.
 
13. RECLASSIFICATIONS
 
     Certain reclassifications have been made to conform to the 1996
presentation.
 
14. INTERIM FINANCIAL INFORMATION
 
     Financial information as of June 30, 1997 and for the six months ended June
30, 1997 and June 30, 1996, included herein, is unaudited. Such information
includes all adjustments (consisting only of normal recurring adjustments),
which are, in the opinion of management, necessary for a fair statement of the
financial information in the interim periods. The results of operations for the
six months ended June 30, 1997 and June 30, 1996 are not necessarily indicative
of the results for the full fiscal year.

NOTE J -- COMMITMENTS AND CONTINGENCIES
 
     In the normal course of business, the Bank is party to financial
instruments with off-balance sheet risk to meet the financing needs of its
customers. These financial instruments include commitments to extend credit and
standby letters of credit. Those instruments involve, to varying degrees,
elements of credit risk in excess of the amount recognized in the balance sheet.
 
     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 notional amount of
those instruments. Commitments under outstanding standby letters of credit
totaled $1,111, $735 and $344 at June 30, 1997, December 31, 1996 and December
31, 1995. Commitments to extend credit totaled $41,584, $36,159 and $13,973 at
June 30, 1997, December 31, 1996 and December 31, 1995. The Bank does not
anticipate any material losses as a result of these commitments.
 
     Commitments to extend credit are agreements to lend to a customer as long
as there is no violation to any condition established in the contract and have
fixed expiration dates or other termination clauses. Some of the commitments are
expected to expire without being drawn upon, so that the total commitment
amounts do not necessarily represent future cash requirements. The Bank
evaluates each customer's credit worthiness on a case-by-case basis. The
extension of credit, is based on management's credit evaluation of the
counter-party. Collateral held varies but may include accounts receivable,
inventory, property, plant, and equipment and income-producing commercial
properties.
 
     Standby letters of credit and financial guarantees written are conditional
commitments issued by the Bank to guarantee the performance of a customer to a
third party. The credit risk involved and collateral required in issuing letters
of credit are essentially the same as those involved in extending loan
facilities to customers.
 
     The Bank is involved in certain claims and lawsuits occurring in the normal
course of business. Management, after consultation with outside legal counsel,
does not believe that the outcome of these actions would have a material impact
on the financial statements of the Company or the Bank.
 
     The Bank leases certain premises and equipment under cancelable and
noncancelable lease arrangements. Total rentals charged to operating expenses
were $135, $187 and $192 in the period ended June 30, 1997, December 31, 1996
and December 31, 1995. Future lease commitments under noncancelable leases are
not material.

     The Company has incentive stock option plans, and at December 31, 1996,
600,000 shares of common stock were reserved for these plans. The exercise price
of each option is equal to the market price of the Company's stock on the date
of grant. The maximum term is 10 years and the shares vest 10% to 20% per year.
The Company applies Accounting Principles Board Opinion 25 and related
Interpretations in accounting for its plans. The effect on net income of
recording compensation cost for the Company's plan, based on the fair value at
the grant date for awards under this plan, consistent with method SFAS No. 123,
Accounting for Stock-Based Compensation, is not significant. Following is a

effect on the Company's and the Bank's financial statements. Under capital
adequacy guidelines and the regulatory framework for prompt corrective action,
the Company and the Bank must meet specific capital
guidelines that involve quantitative measures of the Company's and 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 classifications 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 Company and the Bank to maintain minimum amounts and ratios (set
forth in the table below) of total and Tier I capital (as defined in the
regulations) to risk-weighted assets (as defined), and of Tier I capital (as
defined) to average assets (as defined). Management believes, as of December 31,
1996, that the Company and the Bank meet all capital adequacy requirements to
which they are subject.
 
     The most recent notification from the Federal Deposit Insurance Corporation
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 are no conditions or events since that
notification that management believes have changed the institution's category.
The Company's and the Bank's actual capital amounts and ratios are also
presented in the table.

several branches of First Heights Bank at a premium of $1,212. During 1995, the
Bank sold the assets and liabilities of five branches resulting in a gain of
$2,445.

liabilities assumed, and the excess of cost over the fair value of the net
assets acquired of $3,380, is being amortized over fifteen years using a
straight-line method.

NOTE N -- FAIR VALUES OF FINANCIAL INSTRUMENTS
 
     The fair values of financial instruments are based on management's
estimates and does not purport to represent the aggregate net fair value of the
Company. Further, the fair value estimates are based on various assumptions,
methodologies and subjective considerations, which vary widely among different
financial institutions and which are subject to change.
 
     The following methods and assumptions were used by the Bank in estimating
financial instrument fair values:
 
     - CASH AND CASH EQUIVALENTS, FEDERAL FUNDS PURCHASED AND REPURCHASE
       AGREEMENTS
 
       The balance sheet carrying amount approximates fair value.
 
     - SECURITIES TO BE HELD-TO-MATURITY AND SECURITIES AVAILABLE-FOR-SALE
 
       Fair values for investment securities are based on quoted market prices
       or quotations received from securities dealers. If quoted market prices
       are not available, fair value estimates may be based on quoted market
       prices of similar instruments, adjusted for differences between the
       quoted instruments and the instruments being valued.
 
     - LOANS
 
       Fair values of loans are estimated for segregated groupings of loans with
       similar financial characteristics. Loans are segregated by type such as
       commercial, real estate and consumer loans. Each of these categories is
       further subdivided into fixed and adjustable rate loans and performing
       and nonperforming

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
(INFORMATION AS OF AND FOR THE SIX MONTHS ENDED JUNE 30, 1997 AND JUNE 30, 1996

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
 
NOTE N -- FAIR VALUES OF FINANCIAL INSTRUMENTS -- (CONTINUED)
       loans. The fair value of performing loans is calculated by discounting
       scheduled cash flows through the estimated maturity using estimated
       market discount rates that reflect the credit and interest rate risk
       inherent in the various types of loans. The fair value of nonperforming
       loans is estimated at the value of the underlying collateral.
 
     - DEPOSITS
 
       The fair value of demand deposits, such as non-interest bearing demand
       deposits and interest-bearing transaction accounts such as savings, NOW
       and money market accounts are equal to the amount payable on demand as of
       December 31, 1996 and 1995 (i.e. their carrying amounts).
 
       The fair value of demand deposits is defined as the amount payable, and
       prohibits adjustment for any value derived from the expected retention of
       such deposits for a period of time. That value, commonly referred to as
       the core deposit base intangible, is neither included in the following
       fair value amounts nor recorded as an intangible asset in the balance
       sheet.
 
       The fair value of certificates of deposit is based on the discounted
       value of contractual cash flows. The discount rate used represents rates
       currently offered for deposits of similar remaining maturities. The
       carrying amount of accrued interest payable approximates its fair value.
 
     - OFF-BALANCE-SHEET INSTRUMENTS
 
      Estimated fair values for the Bank's off-balance-sheet instruments are
      based on fees, net of related expenses, currently charged to enter into
      similar agreements, considering the remaining terms of the agreements and
      the counterparties' credit standing.
 
     The following table presents the carrying amounts and fair values of the
Bank's financial instruments at December 31, 1996 and 1995. The fair value of
financial instruments is defined as the amount at which the instrument could be
exchanged in a current transaction between willing parties, other than in a
forced or liquidation sale.
