               NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS

                                  (UNAUDITED)

1.  BASIS OF PRESENTATION

     The interim consolidated financial statements include the accounts of
Prosperity Bancshares, Inc.(SM) (the "Company") and its wholly-owned
subsidiaries, Prosperity Bank(SM) (the "Bank") and Prosperity Holdings, Inc.
These financial statements give retroactive effect to the merger of Commercial
Bancshares, Inc., a Texas corporation ("Commercial") with and into the Company
which was effective on February 23, 2001 and accounted for as a pooling of
interests.  All significant inter-company transactions and balances have been
eliminated.

     The accompanying unaudited interim consolidated financial statements have
been prepared in accordance with generally accepted accounting principles for
interim financial information and with the rules and regulations of the
Securities and Exchange Commission. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, the statements
reflect all adjustments necessary for a fair presentation of the financial
position, results of operations and cash flows of the Company on a consolidated
basis, and all such adjustments are of a normal recurring nature. These
financial statements and the notes thereto should be read in conjunction with
the Company's Annual Report on Form 10-K for the year ended December 31, 2000
and the Company's Current Report on Form 8-K, as amended, dated February 23,
2001. Operating results for the nine month period ended September 30, 2001 are
not necessarily indicative of the results that may be expected for the year
ending December 31, 2001.

               PROSPERITY BANCSHARES, INC.(SM) AND SUBSIDIARIES
        NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)
                               SEPTEMBER 30, 2001
                                  (UNAUDITED)

3.  RECENT ACCOUNTING STANDARDS

     In July 2001, the Financial Accounting Standards Board has issued Statement
of Financial Accounting Standards No. 142 (SFAS 142), "Goodwill and Other
Intangible Assets," which addresses the accounting for goodwill and other
intangible assets. SFAS 142 specifies that, among other things, intangible
assets with an indefinite useful life and goodwill will no longer be amortized.
The standard requires goodwill to be periodically tested for impairment and
written down to fair value if considered impaired. The provisions of SFAS 142
are effective for fiscal years beginning after December 15, 2001, and are
effective for interim periods in the initial year of adoption. The Company is
currently assessing the financial statement impact of the adoption of SFAS 142.

     In June 2001, the Financial Accounting Standards Board approved for
issuance Statement of Financial Accounting Standards No. 141 (SFAS 141),
"Business Combinations". This statement eliminates the pooling method of
accounting for business combinations initiated after June 30, 2001. The Company
does not believe that the adoption SFAS 141 will have a material effect on its
financial statements.

      SFAS No. 133, "Accounting for Derivative Instruments and for Hedging
Activities," establishes accounting and reporting standards for derivative
instruments and requires that an entity recognize all derivatives as either
assets or liabilities in the balance sheet and measure those instruments at fair
value. The implementation of this pronouncement on January 1, 2001 did not have
a material effect on the Company's financial statements.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
                                 OF OPERATIONS

         SPECIAL CAUTIONARY NOTICE REGARDING FORWARD-LOOKING STATEMENTS

      Statements and financial discussion and analysis contained in the
Form 10-Q that are not historical facts are forward-looking statements made
pursuant to the safe harbor provisions of the Private Securities Litigation
Reform Act of 1995. Forward-looking statements are based on assumptions and
involve a number of risks and uncertainties, many of which are beyond the
Company's control. The important factors that could cause actual results to
differ materially from the forward-looking statements include, without
limitation:

 .  changes in interest rates and market prices, which could reduce the
   Company's net interest margins, asset valuations and expense expectations;

 .  changes in the levels of loan prepayments and the resulting effects on the
   value of the Company's loan portfolio;

 .  changes in local economic and business conditions which adversely affect the
   Company's customers and their ability to transact profitable business with
   the company, including the ability of the Company's borrowers to repay their
   loans according to their terms or a change in the value of the related
   collateral.

 .  increased competition for deposits and loans adversely affecting rates and
   terms;

 .  the timing, impact and other uncertainties of future acquisitions, including
   the Company's ability to identify suitable future acquisition candidates, the
   success or failure in the integration of their operations, and the ability to
   enter new markets successfully and capitalize on growth opportunities;

 .  increased credit risk in the Company's assets and increased operating risk
   caused by a material change in commercial, consumer and/or real estate loans
   as a percentage of the total loan portfolio;

 .  the failure of assumptions underlying the establishment of and provisions
   made to the allowance for credit losses;

 .  changes in the availability of funds resulting in increased costs or reduced
   liquidity;

                                       8


 .  increased asset levels and changes in the composition of assets and the
   resulting impact on the Company's capital levels and regulatory capital
   ratios;

 .  the Company's ability to acquire, operate and maintain cost effective and
   efficient systems without incurring unexpectedly difficult or expensive but
   necessary technological changes;

 .  the loss of senior management or operating personnel and the potential
   inability to hire qualified personnel at reasonable compensation levels; and

 .  changes in statutes and government regulations or their interpretations
   applicable to bank holding companies and the Company's present and future
   banking and other subsidiaries, including changes in tax requirements and tax
   rates.

  The Company undertakes no obligation to publicly update or otherwise revise
any forward-looking statements, whether as a result of new information, future
events or otherwise, unless the securities laws require the Company to do so.

ISSUANCE OF PREFERRED SECURITIES OF PROSPERITY STATUTORY TRUST II

     In July 2001, the Company formed Prosperity Statutory Trust II ("Trust II")
and on July 31, 2001, Trust II issued 15,000 Floating Rate Capital Securities
(the "Capital Securities") with an aggregate liquidation value of $15,000,000 to
a third party.  Concurrent with the issuance of the Capital Securities, Trust II
issued trust common securities to the Company in the aggregate liquidation value
of $464,000.  The proceeds of the issuance of the Capital Securities and trust
common securities were invested in the Company's Floating Rate Junior
Subordinated Deferrable Interest Debentures (the "Junior Subordinated
Debentures").  The Junior Subordinated Debentures will mature on July 31, 2031,
which date may be shortened to a date not earlier than July 31, 2006, if certain
conditions are met (including the Company having received prior approval of the
Federal Reserve and any other required regulatory approvals). These Junior
Subordinated Debentures, which are the only assets of Trust II, are subordinate
and junior in right of payment to all present and future senior indebtedness (as
defined in the Indenture dated July 31, 2001) of the Company.  The Junior
Subordinated Debentures will accrue interest at a floating rate equal to 3-month
LIBOR plus 3.58%, not to exceed 12.50%, payable quarterly.  The annual interest
rate on the Debentures for the period from July 31, 2001 through October 30,
2001 is equal to 7.29%.  The quarterly distributions on the Capital Securities
will be paid at the same rate that interest is paid on the Junior Subordinated
Debentures.

     The Company has fully and unconditionally guaranteed the Trust II's
obligations under the Capital Securities.  Trust II must redeem the Capital
Securities when the Junior Subordinated Debentures are paid at maturity or upon
any earlier prepayment of the Junior Subordinated Debentures. The Junior
Subordinated Debentures may be prepaid if certain events occur, including a
change in the tax status or regulatory capital treatment of the Capital
Securities or a change in existing laws that requires Trust II to register as an
investment company.

     For financial reporting purposes, Trust II is treated as a subsidiary of
the Company and consolidated in the corporate financial statements.  The Capital
Securities are treated as Tier 1 capital by the Federal Reserve.  The treatment
of the Capital Securities as Tier 1 capital, in addition to the ability to
deduct the expense of the Junior Subordinated Debentures for federal income tax
purposes, provided the Company with a cost-effective method of raising capital.
The Company received net proceeds of $15.0 million, which will be used for the
general corporate purposes of the Company and the Bank, including supporting
continued expansion activities in the Houston metropolitan area and surrounding
counties through the establishment and/or acquisition of additional Banking
Centers and possible acquisitions.

OVERVIEW

     The Company is a registered financial holding company that derives
substantially all of its revenues and income from the operation of Prosperity
Bank(SM) (the "Bank").  The Bank, which changed its name from First Prosperity
Bank(SM) on May 1, 2001, is a full-service bank that provides a broad line of
financial products and services to small and medium-sized businesses and
consumers through 29 full-service banking locations in the greater Houston
metropolitan area and thirteen contiguous counties situated south and southwest
of Houston and extending into South Texas.

                                       9


     On February 23, 2001, the Company and Commercial completed a merger whereby
Commercial was merged with and into the Company (the "Merger").   In connection
with the Merger, Heritage Bank, Commercial's wholly owned subsidiary, was merged
with and into the Bank.  Heritage Bank had 12 full-service banking locations in
the Houston metropolitan area and in three adjacent counties, including Houston-
Bellaire, Cleveland, Cypress, Fairfield, Houston-Downtown, Houston-Medical
Center, Houston-River Oaks, Houston-Tanglewood/Memorial, Houston-Waugh Drive,
Liberty, Magnolia and Wharton. In connection with the Merger, the Company
incurred approximately $2.4 million in pretax merger-related expenses and other
charges (the "Special Charge").  The transaction was accounted for as a pooling
interests and therefore the historical financial data of the Company has been
restated to include the accounts and operations of Commercial for all periods
prior to the effective time of the Merger.

     Total assets were $1.23 billion at September 30, 2001 compared with $1.15
billion at December 31, 2000.  Total loans increased to $419.6 million at
September 30, 2001 from $411.2 million at December 31, 2000, an increase of
$8.4 million, or 2.0%.  Total deposits were $1.09 billion at September 30, 2001
compared with  $1.03 billion at December 31, 2000, a increase of $58.1 million,
or 5.6%.  Shareholders' equity increased $8.7 million or 10.8%, to $89.0 million
at September 30, 2001 compared with $80.3 million at December 31, 2000.

Results of Operations Excluding Merger-Related Expenses

     If the Company had not incurred the Special Charge of $2.4 million in
connection with the Merger, net income for the nine months ended September 30,
2001 would have been $10.5 million ($1.28 per common share on a diluted basis)
compared with $8.0 million ($0.97 per common share on a diluted basis) for the
nine months ended September 30, 2000, an increase in net income of $2.6 million,
or 32.1%. The Company would have posted a return on average common equity of
16.82%, a return on average assets of 1.20% and an efficiency ratio of 56.36%
for the nine months ended September 30, 2001.

Results of Operations as Reported

     Net income available to common shareholders was $3.7 million  ($0.45 per
common share on a diluted basis) for the quarter ended September 30, 2001
compared with $2.7 million ($0.33 per common share on a diluted basis) for the
quarter ended September 30, 2000, an increase in net income of  $1.0 million, or
37.0%.  The Company posted returns on average common equity of 17.34% and
14.82%, returns on average assets of 1.25% and 1.07% and efficiency ratios of
55.07% and 61.54% for the quarters ended September 30, 2001 and 2000,
respectively.

     Net income available to common shareholders for the nine months ended
September 30, 2001 was $9.0 million ($1.09 per common share on a diluted basis)
compared with $8.0 million ($0.97 per common share on a diluted basis) for the
same period in 2000, an increase in net income of $986,000 or 12.4%. The Company
posted returns on average common equity of 14.30% and 14.98%, returns on average
assets of 1.02% and 1.04% and efficiency ratios of 63.38% and 61.83% for the
nine months ended September 30, 2001 and 2000, respectively.

RESULTS OF OPERATIONS

Net Interest Income

     Net interest income was $10.3 million for the quarter ended September 30,
2001 compared with $8.6 million for the quarter ended September 30, 2000, an
increase of $1.6 million, or 18.9%. Net interest income increased primarily due
to an increase in the amount of interest earning assets and a decrease in the
average rate paid on interest-bearing liabilities. As a result, the net interest
margin on a tax-equivalent basis increased to 3.84% from 3.79% for the same
periods. Average interest-earning assets increased to $1.12 billion for the
quarter ended September 30, 2001 compared with $944.0 million for the quarter
ended September 30, 2000, an increase of $178.0 million, or 18.9%. The average
rate on interest bearing liabilities decreased 78 basis points to 3.94% for the
three months ended September 30, 2001 compared with 4.72% for the same period in
2000. The Company's average rate on interest-bearing liabilities decreased due
to the cuts in the discount rate by the Federal Reserve during 2001.

     Net interest income increased $3.6 million, or 14.0%, to $29.3 million for
the nine months ended September 30, 2001 compared with $25.7 million for the
same period in 2000. This increase is mainly attributable to higher average
interest-earning assets resulting from purchases of investment securities and
increased loan originations. Average interest-earning assets increased to $1.10
billion for the nine months ended September 30, 2001 compared with $939.3
million for the nine months ended September 30, 2000, an increase of $157.1
million, or 16.7%. The net interest margin on a tax-equivalent basis decreased
to 3.74% compared with 3.78% for the same periods. This decrease is attributable

                                       10


to a 25 basis point decrease in the yield on total average interest-earning
assets for the nine months ended September 30, 2001 partially offset by a 21
basis point decrease in rate paid on total average interest-bearing liabilities
for the same period.

  The Company's net interest income is affected by changes in the amount and mix
of interest-earning assets and interest-bearing liabilities, referred to as a
"volume change."  It is also affected by changes in yields earned on interest-
earning assets and rates paid on interest-bearing deposits and other borrowed
funds, referred to as a "rate change."

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

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

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

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

(3)  In order to make pretax income and resultant yields on tax-exempt
     investments and loans comparable to those on taxable investments and loans,
     a tax-equivalent adjustment has been computed using a federal income tax
     rate of 35% and 34% for the nine months ended September 30, 2001 and

Provision for Credit Losses

     Management actively monitors the Company's asset quality and provides
specific loss provisions when necessary.  Loans are charged-off against the
provision for credit losses when appropriate.  Although management believes it
uses the best information available to make determinations with respect to the
provision for credit losses, future adjustments may be necessary if economic
conditions differ from the assumptions used in making the initial
determinations.  As of September 30, 2001, the allowance for credit losses
amounted to $5.5 million, or 1.32% of total loans compared with $5.5 million, or
1.34% of total loans at December 31, 2000.

                                       14


     Provisions for credit losses are charged to income to bring the total
allowance for credit losses to a level deemed appropriate by management of the
Company based on such factors as historical loan loss experience, industry
diversification of the commercial loan portfolio, the amount of nonperforming
loans and related collateral, the volume growth and composition of the loan
portfolio, current economic conditions that may affect the borrower's ability to
pay and the value of collateral, the evaluation of the loan portfolio through
the internal loan review function and other relevant factors.

     The Company made a $50,000 provision for credit losses for the three months
ended September 30, 2001, a decrease from the provision of $75,000 for the same
period in 2000. This was the only provision made for the nine months ended
September 30, 2001, a decrease from the provision of $225,000 for the
corresponding period in 2000.

Noninterest Income

     The Company's primary sources of noninterest income are service charges on
deposit accounts and other banking service related fees.  The following table

due to the one-time merger related charges associated with the Merger with
Commercial and an increase in minority interest trust preferred securities
expense related to the issuance of additional trust preferred securities in July
2001.  See "Issuance of Preferred Securities of Prosperity Statutory Trust II"
for a more detailed description of the issuance.

Nonperforming Assets

     The Company had $539,000 in nonperforming assets at September 30, 2001
compared with $1.3 million in nonperforming assets at December 31, 2000, a
decrease of $796,000 or 59.6%. The decrease was principally due to the sale of
other real estate and a decrease in accruing loans 90 or more days past due. Of
the $539,000 in nonperforming loans, $411,000 is attributed to one nonaccrual
loan. The Company generally places a loan on nonaccrual status and ceases
accruing interest when the payment of principal or interest is delinquent for 90
days, or earlier in some cases, unless the loan is in the process of collection
and the underlying collateral fully supports the carrying value of the loan. The
Company generally charges off all loans before attaining nonaccrual status.

      The following table presents information regarding nonperforming assets as
of the dates indicated:

Allowance for Credit Losses

   Management actively monitors the Company's asset quality and provides
specific loss allowances when necessary.  Loans are charged-off against the
allowance for credit losses when appropriate.  Although management believes it
uses the best information available to make determinations with respect to the
allowance for credit losses, future adjustments may be necessary if economic
conditions differ from the assumptions used in making the initial
determinations.  As of September 30, 2001, the allowance for credit losses
amounted to $5.5 million, or 1.32% of total loans compared with $5.5 million, or
1.34% of total loans at December 31, 2000.

                                       17

Securities

     Securities totaled $725.0 million at September 30, 2001 compared with
$587.0 million at December 31, 2000, an increase of $138.1 million or 23.5%. The
increase is primarily attributable to an increase in deposits as the Company
used the excess liquidity to purchase securities. At September 30, 2001,
securities represented 58.9% of total assets compared with 51.2% of total assets
at December 31, 2000.

Premises and Equipment

     Premises and equipment, net of accumulated depreciation, totaled $14.9
million at September 30, 2001 and $14.5 million at December 31, 2000.

Deposits

     Total deposits were $1.09 billion at September 30, 2001 compared with $1.03
billion at December 31, 2000, an increase of $58.1 million. At September 30,
2001, noninterest-bearing deposits accounted for 16.7% of total deposits
compared with 18.2% of total deposits at December 31, 2000.  Interest-bearing
deposits totaled $909.3 million, or 83.3%, of total deposits at September 30,
2001 compared with $845.6 million, or 81.8%, of total deposits at December 31,
2000.

Other Borrowings

     The Company had no notes payable and $13.5 million in Federal Home Loan
Bank ("FHLB") advances at September 30, 2001, compared with no notes payable and
$13.9 million in FHLB advances at December 31, 2000.  The FHLB advances are
secured by a blanket lien on the Bank's first mortgage loans against one-to-four
family residential properties.  The maturity dates range from the years 2004 to
2018 and have interest rates ranging from

                                       18


5.95% to 6.48%. In addition, the Company had no federal funds purchased on
September 30, 2001 or December 31, 2000.

Trust Preferred Securities

     In July 2001, the Company formed Trust II and on July 31, 2001, Trust II
issued 15,000 Floating Rate Capital Securities with an aggregate liquidation
value of $15.0 million to a third party. The proceeds of the issuance were
invested in the Company's Floating Rate Junior Subordinated Debentures which
mature on July 31, 2031, which date may be shortened to a date not earlier than
July 31, 2006, if certain conditions are met. For a more detailed description of
the issuance, see "Issuance of Preferred Securities of Prosperity Statutory
Trust II."

     As a result of the issuance by Trust II, the Company's subsidiary trusts
had outstanding $27.0 million in trust preferred securities at September 30,
2001 compared with the $12.0 million of trust preferred securities issued by
Prosperity Capital Trust I ("Trust I") outstanding at December 30, 2000. The
Company's 9.60% junior subordinated debentures issued to Trust I mature on
November 17, 2029, which date may be shortened to a date not earlier than
November 17, 2004, if certain conditions are met.

Liquidity

     Effective management of balance sheet liquidity is necessary to fund growth
in earning assets and to pay liability maturities, depository customers'
withdrawal requirements and shareholders' dividends.  The Company has numerous
sources of liquidity including a significant portfolio of shorter-term assets,
marketable investment securities (excluding those presently classified as "held-
to-maturity"), increases in customers' deposits, and access to borrowing
arrangements.  Available borrowing arrangements maintained by the Company
include federal funds lines with other commercial banks and an advancement
arrangement with the FHLB.

     Asset liquidity is provided by cash and assets which are readily marketable
or which will mature in the near future.  As of September 30, 2001, the Company
had cash and cash equivalents of $41.0 million, down from $99.2 million at
December 31, 2000.  The decline was due primarily to a decrease in federal funds
sold of $49.9 million.

Capital Resources

  Total shareholders' equity was $89.0 million at September 30, 2001 compared
with $80.3 million at December 31, 2000, an increase of $8.7 million, or 10.8%.
The increase was primarily due to net earnings of $9.0 million and a net change
in unrealized gain on available for sale securities of $3.1 million, offset by
cash dividends paid of $2.4 million, cash paid to dissenting shareholders in
connection with the issuance of common stock in exchange for common stock of
Commercial of $668,000 and trust preferred issuance costs of $476,000.

  Both the Board of Governors of the Federal Reserve System, with respect to the
Company, and the Federal Deposit Insurance Corporation ("FDIC"), with respect to
the Bank, have established certain minimum risk-based capital standards that
apply to bank holding companies and federally insured banks.  As of September
30, 2001, the Company's  Tier 1 capital, total risk-based capital and leverage
capital ratios were 17.53%, 18.61% and 7.62%, respectively.  As of September 30,
2001, the Bank's risk-based capital ratios were above the levels required for
the Bank to be designated as "well capitalized" by the FDIC, with Tier-1
capital, total risk-based capital and leverage capital ratios of 14.73%, 15.82%
and 6.40%, respectively.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

  The Company manages market risk, which for the Company is primarily interest
rate risk, through its Asset Liability Committee which is composed of senior
officers of the Company, in accordance with policies approved by the Company's
Board of Directors.

  The Company uses simulation analysis to examine the potential effects of
market changes on net interest income and market value.  It considers
macroeconomic variables, Company strategy, liquidity and other factors as it
quantifies market risk.  There have been no material changes of this nature
since December 31, 2000.  See the Company's Annual Report on Form 10-K, Item 7
"Management's Discussion and Analysis and Results of Operations-Interest Rate
Sensitivity and Liquidity".
