| The June 30, 2006 and 2005   financial statements included herein are unaudited; however, such information   reflects all adjustments (consisting solely of normal recurring adjustments),   which are, in the opinion of management of the registrant, necessary to a   fair statement of the results for the interim periods.  The financial statements for the year   ended December 31, 2005 included herein are headed “unaudited.”  These financial statements were reported   as “audited” in our Annual Report on Form 10-K for the year ended December   31, 2005 filed with the Securities and Exchange Commission but are required   to be reflected herein as unaudited because of the absence of an independent   auditor’s report. |

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

SUMMIT BANCSHARES, INC. AND SUBSIDIARIESFOR THE SIX MONTHS ENDED JUNE 30, 2006 AND 2005 (UNAUDITED) AND FOR THE YEAR ENDED DECEMBER 31, 2005 (UNAUDITED)

NOTE 1 - Summary of Significant Accounting and Reporting Policies

          The accounting and reporting policies of Summit Bancshares, Inc. are in accordance with accounting principles generally accepted in the United States of America and the prevailing practices within the banking industry.  A summary of the more significant policies follows:

Basis of Presentation and Principles of Consolidation

          The consolidated financial statements of Summit Bancshares, Inc. (hereinafter, collectively with its subsidiaries, the “Corporation”), include its accounts and its direct and indirect wholly-owned subsidiaries, Summit Delaware Financial Corporation, Summit Bank, National Association (the “Bank”) and SIA Insurance Agency, Inc. (“SIA”).  All significant intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

          The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods.  Actual results could differ materially from those estimates.

Cash and Due From Banks

          The Bank is required to maintain certain noninterest-bearing cash balances at the Federal Reserve Bank based on its level of deposits. During the first six months of 2006, the average cash balance maintained at the Federal Reserve Bank was $2,661,000. Compensating balances held at correspondent banks, to minimize service charges, averaged approximately $24,221,000 during the same period.

Investment Securities

          The Corporation has adopted Statement of Financial Accounting Standards No. 115,*“Accounting for Certain Investments in Debt and Equity Securities”* (“SFAS 115”).  At the date of purchase, the Corporation 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 inearnings.  Investments not classified as either held-to-maturity or trading are classified as available-for-sale and measured at fair value in the financial statements with unrealized gains and losses reported, net of tax, in a separate component of shareholders’ equity until realized.

          The Corporation has the ability and intent to hold to maturity its investment securities classified as held-to-maturity; accordingly, no adjustment has been made for the excess, if any, of amortized cost over market.  In determining the investment category classifications at the time of purchase of securities, management considers its asset/liability strategy, changes in interest rates and prepayment risk, the need to increase capital and other factors.  Under certain circumstances (including the deterioration of the issuer’s creditworthiness, a change in tax law, or statutory or regulatory requirements), the Corporation may change the investment security classification.  In the periods reported for 2006 and 2005, the Corporation held no securities that would have been classified as trading securities.

          All investment securities are adjusted for amortization of premiums and accretion of discounts.  Amortization of premiums and accretion of discounts are recorded to income over the contractual maturity or estimated life of the individual investment on the level yield method.  Gain or loss on sale of investments is based upon the specific identification method and the gain or loss is recorded in non-interest income.  Income earned on the Corporation’s investments in securities issued by state and political subdivisions is not taxable.

Loans and Allowance for Loan Losses

          Loans are stated at the principal amount outstanding less unearned discount, deferred fees and the allowance for loan losses.  Unearned discount on installment loans is recognized as income over the terms of the loans by a method approximating the interest method.  Interest income on all other loans is recognized based upon the principal amounts outstanding, the simple interest method.  Loan origination fee income, net of direct loan origination costs, is deferred and amortized over the life of the related loan.  The accrual of interest on a loan is discontinued when, in the opinion of management, there is doubt about the ability of the borrower to pay interest or principal.  Interest previously earned, but uncollected on such loans, is written off.  After loans are placed on non-accrual all payments received are applied to principal and no interest income is recorded untilthe loan is returned to accrual status or the principal balance has been reduced to zero.

NOTE 1 - Summary of Significant Accounting and Reporting Policies (cont’d.)

          The Corporation has adopted Statement of Financial Accounting Standards No. 114, “Accounting by Creditors for Impairment of a Loan,” as amended by Statement of Financial Accounting Standards No. 118, “Accounting by Creditors for Impairment of a Loan - Income Recognition and Disclosure.”  Under this standard, the allowance for loan losses related to loans that are identified for evaluation in accordance with Statement No. 114 (impaired loans) is based on discounted cash flows using the loan’s initial effective rate or the fair value of the collateral for certain collateral dependent loans.

          The allowance for loan losses is comprised of amounts charged against income in the form of a provision for loan losses for certain loans when it is probable that all amounts due pursuant to the contractual terms of the loan will not be collected.  In these situations, a valuation allowance is recorded when the carrying amount of the loan exceeds the discounted cash flows using the loan’s initial effective interest rate or the fair value of the collateral for certain collateral dependent loans.  Income on impaired loans is recognized based on the collectibility of the principal amount.  Adjustments to the allowance for loan losses will be reported in the period such adjustments become known or are reasonably estimable.

          The amount maintained in the allowance reflects management’s continuing assessment of the potential losses inherent in its loan portfolio based on its evaluation of a number of factors, including the Bank’s loss experience in relation to outstanding loans and the existing level of the allowance, prevailing and prospective economic conditions, and management’s continuing review of the discounted cash flow values of impaired loans and its evaluation of the quality of the loan portfolio.  Loans are charged against the allowance for loan losses when management believes that the collectibility of the principal is unlikely.

          The evaluation of the adequacy of loan collateral is often based upon estimates and appraisals.  Because of changing economic conditions, the valuations determined from such estimates and appraisals may also change.  Accordingly, the Corporation may ultimately incur losses which vary materially from management’s current estimates.  

Premises and Equipment

          Land is carried at cost.  Premises and equipment are stated at cost less accumulated depreciation and amortization.  Depreciation expense is computed on the straight-line method based upon the estimated useful lives of the assets ranging from three to forty years.  Maintenance and repairs are charged to non-interest expense.  Renewals and betterments are added to the asset accounts and depreciated over the periods benefited.  Depreciable assets sold or retired are removed from the asset and related accumulated depreciation accounts and any gain or loss is reflected in the income and expense accounts.

Other Real Estate

          Other real estate is foreclosed property held pending disposition and is valued at the lower of its fair value or the recorded investment in the related loan.  At foreclosure, if the fair value, less estimated costs to sell, of the real estate acquired is less than the Corporation’s recorded investment in the related loan, a write-down is recognized through a charge to the allowance for loan losses.  Any subsequent reduction in value is recognized by a charge to income.  Operating expenses of such properties, net of related income, and gains and losses on their disposition are included in non-interest expense.

Federal Income Taxes

          The Corporation joins with its subsidiaries in filing a consolidated federal income tax return.  The subsidiaries pay to the parent a charge equivalent to their current federal income tax based on the separate taxable income of the subsidiaries.

          The Corporation and the subsidiaries maintain their records for financial reporting and income tax reporting purposes on the accrual basis of accounting.  Deferred income taxes are provided in accordance with Statement of Financial Accounting Standards No. 109, “Accounting for Income Taxes.”  Deferred income taxes are provided for accumulated temporary differences due to basic differences for assets and liabilities for financial reporting and income tax purposes.

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

Cash and Cash Equivalents

          For the purpose of presentation in the Statements of Cash Flows, cash and cash equivalents include cash on hand, clearings and exchanges, and balances due from correspondent banks.  

Reclassification

          Certain reclassifications have been made to the 2005 financial statements to conform to the 2006 presentation.

NOTE 1 - Summary of Significant Accounting Policies (cont’d.)

Earnings Per Common and Common Equivalent Shares

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

Stock-Based Compensation

          On January 1, 2006, the Corporation changed its accounting policy related to stock-based compensation in connection with the adoption of Statement of Financial Accounting Standards (SFAS) No. 123, “Share-Based Payment (Revised 2004).”  See Note 12 – Stock-Based Compensation for additional information.

Advertising Costs

          Advertising costs are expensed as incurred.

Comprehensive Income

          Comprehensive income includes all changes in shareholders’ equity during a period, except those resulting from investments by and distributions to owners and treasury stock transactions.  Besides net income, the other component of the Corporation’s comprehensive income is the after tax effect of changes in the fair value of securities available-for-sale.  Comprehensive income for the periods ended June 30, 2006 and 2005 and for the year ended December 31, 2005 is reported in Note 26, “Comprehensive Income.”

Audited Financial Statements

          The consolidated balance sheet as of December 31, 2005, and the consolidated statements of income, changes in shareholders’ equity and cash flows for the year ended December 31, 2005 are headed “unaudited” in these financial statements.  These statements were reported as “audited” in our Annual Report of Form 10-K for the year ended December 31, 2005 filed with the Securities and Exchange Commission but are required to be reflected in these statements as unaudited because of the absence of an independent auditor’s report.

NOTE 2 – Acquisition

          On March 21, 2005, the Corporation acquired Dignum Financial Services (“DFS”) for a purchase price of approximately $1.0 million.  DFS was a proprietorship engaged in financial planning and management services.  Of the purchase price $0.5 million is subject to the earnings performance of Summit Financial Partners (formerly DFS), a division of the Bank.

NOTE 6 – Goodwill and Other Intangible Assets

          Goodwill represents the excess of the purchase price over the fair value of net assets acquired in business combinations under the purchase method of accounting.  The Corporation has adopted Financial Accounting Standards Board Statement No. 142 (FAS 142), “Goodwill and Other Intangible Assets.”  FAS 142 eliminates amortization of goodwill associated with business combinations completed after June 30, 2001.  Goodwill is periodically assessed for impairment when events or changes in circumstances indicate that the carrying value of the asset may not be recoverable.  The Corporation bases its evaluation on such impairment factors as the nature of the assets, the future economic benefit of the assets, any historical or future profitability measurements, as well as other external market conditions or factors that may be present.

NOTE 6 – Goodwill and Other Intangible Assets (cont’d.)

          On May 3, 2004, the Corporation completed its merger with ANB Financial Corporation and its wholly-owned subsidiary, Arlington National Bank of Arlington, Texas (“collectively “ANB”).  A premium of $10.7 million was paid in connection with the acquisition of ANB, $2.7 million of which was identified as core deposit intangibles.  The remaining $8.0 million has been recorded as goodwill.  In accordance with FAS 142, the goodwill will not be amortized.  The core deposit intangibles are being amortized using a straight line method over their estimated useful life of 8 years.  Amortization expense on the core deposit intangibles was $164,000, $328,000 and $164,000 for the six months ended June 30, 2006, the year ended December 31, 2005 and the six months ended June 30, 2005, respectively.

NOTE 10 – Note Payable

          On September 15, 2005, the Corporation obtained a line of credit from a bank under which the Corporation may borrow $10,000,000 at a floating rate (three month LIBOR plus margin of 2.00%).  The line of credit is secured by stock of the Bank and matures on September 15, 2006, whereupon, if balances are outstanding, the line converts to a term note having a five year term.  The Corporation will not pay a fee for any unused portion of the line.  As of June 30, 2006, there were no borrowings under this line.  

NOTE 11 - Junior Subordinated Deferrable Debentures

          On May 3, 2004, the Corporation formed SBI Trust and SBI Trust subsequently issued $12.0 million of floating rate (three month LIBOR plus a margin of 2.65%) Capital Securities (the “Trust Capital Securities”).  Concurrent with the issuance of the Trust Capital Securities, SBI Trust issued trust common securities to the Corporation in the aggregate liquidation value of $372,000.  The proceeds of the issuance of the Trust Capital Securities and trust common securities were invested in the Corporation’s Floating Rate Junior Subordinated Deferrable Debentures (the “Deferrable Debentures”), which mature on July 7, 2034 and have a call feature that permits the Corporation to redeem any or all of the securities after July 7, 2009.  The interest rate on the Deferrable Debentures at June 30, 2006 and December 31, 2005 was 7.72% and 6.80%, respectively.  The DeferrableDebentures, which are the only assets of SBI Trust, are subordinated and junior in right of payment to all present and future senior indebtedness (as defined in the Indenture dated May 3, 2004) of the Corporation.

NOTE 12 - Stock -Based Compensation

          Prior to January 1, 2006, the Corporation accounted for stock-based compensation utilizing the intrinsic value method in accordance with the provisions of Accounting Principles Board Opinion No. 25 (APB 25), “Accounting for Stock Issued to Employees” and related Interpretations.  Accordingly no compensation expense was recognized for stock option plans because the exercise prices of stock options equaled or exceeded the market prices of the underlying stock on the dates of the grants.  However, stock-based compensation has been included in pro forma disclosures in the financial statement footnotes in prior periods. 

          Effective January 1, 2006, the Corporation adopted the fair value recognition provisions of SFAS No. 123R, “Share-Based Payment” using a modified version of prospective application.  Under this method, compensation expense will be recorded for all awards granted after the date of adoption and for the unvested portion of previously granted awards that were outstanding as of the beginning of the period of adoption.

          For the six months ended June 30, 2006, stock-based compensation expense was $102,000.

NOTE 15 - Related Party Transactions

          The Bank has made loan transactions in the ordinary course of business with certain of its and the Corporation’s officers, directors and their affiliates. All loans included in such transactions are made on substantially the same terms, including interest rate and collateral, as those prevailing at the time for comparable transactions with other unrelated persons and all such loans are current as to principal and interest payments.  Total loans outstanding to such related parties amounted to approximately $8,108,000 at June 30, 2006 and $9,356,000 at December 31, 2005.

NOTE 16 - Commitments and Contingent Liabilities

          In the normal course of business, there are various outstanding commitments and contingent liabilities, such as guarantees and commitments to extend credit, which are not reflected in the financial statements.  No losses are anticipated as a result of these transactions. Commitments are most frequently extended for real estate, commercial and industrial loans.

          At June 30, 2006, outstanding documentary and standby letters of credit totaled $7,311,000 and commitments to extend credit totaled $230,352,000.

          In addition, the Corporation leases certain office facilities under operating leases.  Rent expense for all operating leases totaled $696,000 and $606,000 for the six months ended June 30, 2006 and 2005, respectively, and $1,305,000 for the year ended December 31, 2005.

NOTE 17 - Stock Option Plans

          On April 18, 2006, the shareholders of the Corporation approved the 2006 Long-Term Incentive Plan of the Corporation (the “2006 Plan”).  The 2006 Plan replaced the 1997 Stock Option Plan and is intended to enable the Corporation to remain competitive and innovative in its ability to attract, motivate, reward and retain the services of key employees.  The 2006 Plan provides for the granting of stock options, stock appreciation rights, restricted stock, restricted stock units, performance awards, dividend equivalent rights, and other awards which may be paid in cash or stock.  The 2006 Plan is expected to provide flexibility to the Corporation’s compensation methods in order to adapt the compensation of key employees to a changing business environment, after giving due consideration to competitive conditions and the impact of federal tax laws.  Subject to certainadjustments, the number of the Corporation’s shares of common stock that may be issued pursuant to awards under the 2006 Plan is 1,250,000 shares, less the total number of shares of common stock issued pursuant to the 2006 Plan or issuable upon the exercise of awards granted under the 1997 Stock Option Plan. No more options may be granted under the 1993 Stock Option Plan or the 1997 Stock Option Plan of the Corporation, each of which has terminated.  Each award granted under the 1997 Stock Option Plan is now subject to the 2006 Plan.  The stock options granted under the 2006 Plan will generally be exercisable for ten years from the date of grant and generally vest ratably over a five year period.  Options have been granted at prices which will not be less than 100-110% of the fair market value of the underlying common stock at the date of grant.

          The following is a summary of transactions during the periods presented:

See Note 12 “Stock–Based Compensation” for information regarding the dilutive impact ofthese stock options.

NOTE 18 - Employee Benefit Plans

401(k) Plan

          The Corporation implemented a 401(k) plan in December 1997 covering substantially all employees.  The Corporation made no contribution to this plan in 1998 or 1999.  Beginning in 2000, the Corporation made matching contributions, not to exceed 6% of the employee’s annual compensation, to the participants’ deferrals of compensation up to 100% of the employee contributions.

          The amount expensed in support of the plan was $336,000 and $294,000 during the first six months of 2006 and 2005, respectively, and $592,000 for the year 2005.

Supplemental Executive Retirement Plan

          In 2002, the Corporation established a Supplemental Executive Retirement Plan (the “Retirement Plan”) to provide key employees with retirement, death or disability benefits.  For currently employed employees, the Retirement Plan replaces the previous Management Security Plan.  The Retirement Plan is a defined contribution plan and the expense charged to earnings relating to the Retirement Plan was $267,000 and $227,000 for the first six months of 2006 and 2005, respectively, and $458,000 for the year 2005. 

Employment Contracts

          The Chief Executive Officer of the Corporation has entered into a severance agreement with the Corporation providing for salary and fringe benefits in the event of termination for other than cause and under certain changes in control.

Other Post Retirement Benefits

          The Corporation provides certain health care benefits for certain retired employees who bear all costs of these benefits.  These benefits are covered under the Consolidated Omnibus Budget Reconciliation Act.

NOTE 18 - Employee Benefit Plans (cont’d.)

Compensated Absences

          Employees of the Corporation are entitled to paid vacation, paid sick days and other personal days off, depending on job classification, length of service and other factors.  It is impracticable to estimate the amount of compensation for future absences, and accordingly, no liability has been recorded in the accompanying financial statements.  The Corporation’s policy is to recognize the costs of compensated absences when actually paid to employees.

NOTE 19 - Earnings per Share

          The following data shows the amounts used in computing earnings per share (“EPS”) and the weighted average number of shares of dilutive potential common stock (dollars in thousands):

NOTE 20 - Financial Instruments with Off-Balance Sheet Risk

          The Corporation is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers.  These financial instruments include loan commitments, standby letters of credit and documentary letters of credit.  The instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the financial statements.

          The Corporation’s exposure to credit loss in the event of non-performance by the other party of these loan commitments and letters of credit is represented by the contractual amount of those instruments.  The Corporation uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments.

          The total contractual amounts of financial instruments with off-balance sheet risk are as follows (in thousands):

|                                                                  |   | **June 30,** |    |
|-----------------------------------------------------------------------|--------|--------------|---------|
|                                                                  |   |              |    |
|                                                                  |   | **2006**     |    | **2005** |   |
|                                                                  |   |              |    |  |   |
| Financial   Instruments Whose Contract Amounts Represent Credit Risk: |   |         |    |   |   |   |   |
| Loan Commitments Including Unfunded Lines of   Credit                 |   | $            | 230,352 |   | $ | 195,308 |   |
| Letters of Credit                                                     |   |         | 7,311   |   |   | 6,411 |   |

          Loan commitments are agreements to lend to a customer as long as there is no customer violation of any condition established in the contract.  Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee.  Letters of credit are conditional commitments by the Corporation to guarantee the performance of a customer to a third party.  The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

          Since many of the loan commitments and letters of credit may expire without being drawn upon, the total commitment amount does not necessarily represent future cash requirements.  The Corporation evaluates each customer’s credit worthiness on a case-by-case basis.  The amount of collateral obtained, if deemed necessary by the Corporation upon extension of credit, is based on management’s credit evaluation of the counterparty.  Collateral held varies but may include accounts receivable, inventory, property, plant and equipment, owner-occupied real estate and income-producing commercial properties.

NOTE 20 - Financial Instruments with Off-Balance Sheet Risk (cont’d.)

          The Corporation originates real estate, commercial and consumer loans primarily to customers in the Tarrant County area.  Although the Corporation has a diversified loan portfolio, a substantial portion of its customers’ ability to honor their contracts is dependent upon the local economy and the real estate market.

          The Corporation maintains funds on deposit at correspondent banks which at times exceed the federally insured limits.  Management of the Corporation monitors the balance in these accounts and periodically assesses the financial condition of correspondent banks.

NOTE 21 - Concentrations of Credit Risk

          The Bank makes commercial, consumer and real estate loans in its direct market which is defined as Fort Worth and its surrounding area.  The Board of Directors of the Bank monitors concentrations of credit by purpose, collateral and industry at least quarterly.  Certain limitations for concentration are set by the Board of Directors of the Bank.  Additional loans in excess of these limits must have prior approval of the Bank’s directors’ loan committee.  Although the Bank has a diversified loan portfolio, a substantial portion of its debtors’ abilities to honor their contracts is dependent upon the strength of the local and state economy.

NOTE 22 - Litigation

          The Corporation is involved in legal actions arising in the ordinary course of business.  It is the opinion of management, after reviewing such actions with outside legal counsel, that the settlement of these matters will not materially affect the Corporation’s financial position.

NOTE 23 - Stock Repurchase Plan

          On April 18, 2006, the Board of Directors of the Corporation approved a stock purchase plan (the “2006 Stock Purchase Plan”) authorizing management to purchase up to 623,675 shares of the Corporation’s common stock on behalf of the Corporation over the twelve-month period beginning April 19, 2006 and ending on April 18, 2007, including in open market transactions, privately negotiated transactions or other transactions in accordance with all applicable state and federal laws and regulations. In the quarter ended June 30, 2006, 29,200 shares were purchased by the Corporation pursuant to the 2006 Stock Purchase Plan in privately negotiated transactions.

          The Corporation’s ability to purchase shares of the Corporation’s common stock is subject to various banking laws, regulations and policies as well as rules and regulations of the Securities and Exchange Commission.  

NOTE 24 - Subsequent Events 

          On July 2, 2006, the Corporation and Cullen/Frost Bankers, Inc., a Texas corporation (“Cullen/Frost”), entered into an Agreement and Plan of Merger (the “Agreement”) pursuant to which the Corporation will merge with and into Cullen/Frost. Under the terms of the Agreement, the Corporation’s shareholders will have the right, subject to pro-ration, to elect to receive cash, shares of Cullen/Frost common stock or a combination thereof having a value equal to $11.50 plus 0.2933 Cullen/Frost shares. The total consideration consists of approximately $143.4 million in cash and approximately 3.84 million shares of Cullen/Frost common stock (assuming the treasury stock method of accounting for options before giving effect to any exercises of outstanding options). The transaction is subject to customary closing conditions, including the receipt of regulatory approvals andapproval of the shareholders of the Corporation. The merger is currently expected to be completed in the fourth quarter of 2006, although delays could occur. 

          The foregoing summary of the Agreement is not complete and is qualified in its entirety by reference to the complete text of such document, which is filed as Exhibit 2.1 to the Report on Form 8-K filed with the Securities and Exchange Commission on July 3, 2006 and  which is incorporated herein by reference. 

          On July 18, 2006, the Board of Directors of the Corporation approved a quarterly dividend of $.08 per share to be paid on August 15, 2006 to shareholders of record on August 7, 2006.  

NOTE 25 - Fair Values of Financial Instruments

          The following methods and assumptions were used by the Corporation in estimating its fair value disclosures for financial instruments:

|   | *Cash and cash equivalents:*    The carrying amounts reported in the balance sheet for cash and due   from banks and federal funds sold approximate those assets’ fair values.                                                                                                        |
|--------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | *Investment securities (including mortgage backed   securities):*  Fair values for investment securities are   based on quoted market prices, where available.  If quoted market prices are not available, fair values are   based on quoted market prices of comparable instruments. |

NOTE 25 - Fair Values of Financial Instruments (cont’d.)

|   | *Loans:*  For variable rate loans, fair   values are based on carrying values.    The fair values for fixed rate loans such as mortgage loans (e.g.,   one-to-four family residential) and installment loans are estimated using   discounted cash flow analysis.  The   carrying amount of accrued interest receivable approximates its fair value.                                                                                                                                                                                                       |

|   | *Deposit liabilities:*    The fair value disclosed for interest-bearing and noninterest-bearing   demand deposits, passbook savings, and certain types of money market accounts   are, by definition, equal to the amount payable on demand at the reporting   date or their carrying amounts.  Fair   values for fixed rate certificates of deposit are estimated using a   discounted cash flow calculation that applies interest rates currently being   offered on certificates to a schedule of aggregated expected monthly maturities   on time deposits. |

|   | *Short term borrowings:*    The carrying amounts of borrowings under repurchase agreements,   Federal Home Loan Bank advances and Federal Funds Purchased approximate their   fair values.                                                                                                                                                                                                                                                                                                                                                                           |

NOTE 27 – Dividends from Subsidiaries

          The primary source of funds for the Corporation is cash dividends received from the Bank.  The amount of dividends that the Bank may pay in any one year, without the approval of the Comptroller of the Currency, is the sum of the retained net profits for the preceding two years plus its total of the retained net profits for the current year. Under this formula, as defined, as of June 30, 2006, the Bank can legally initiate dividend payments of $16,139,000 for the remainder of 2006.  The Bank is also restricted from paying dividends that would cause the Bank to be under-capitalized.

          Internal dividend policies limit dividends paid by the Bank if its equity capital falls below certain minimum levels as determined by the Bank’s Board of Directors.

Overview

          Our business has been conducted primarily through our wholly-owned subsidiaries, Summit Bank, National Association (the “Bank”) and Summit Delaware Financial Corporation.  The Bank currently operates its branch offices in twelve locations in Tarrant County, Texas.

          Our results of operations are primarily dependent on net interest income, which is the difference between the income earned on our loans and investment portfolios and our cost of funds, consisting of the interest paid on deposits and borrowings.  Results of operations are also affected by our allowance for loan losses, investment activities, loan servicing fees and other fees.  Our non-interest expense principally consists of salary and benefits, occupancy and equipment expense, business development costs, professional fees, data processing expense and other expenses.

          Net income for the second quarter of 2006 was $3,523,000, which represented an increase of $332,000, or 10.4%, compared to $3,191,000 for the second quarter of 2005.  On a weighted average share basis, net income for the second quarter of 2006 was $0.28 per diluted share as compared to $0.25 per diluted share for the second quarter of 2005, an increase of 12.0%.  The increase in net income for the second quarter of 2006 reflected an increase in net interest income (tax equivalent) of $1,981,000, or 18.4%, over the second quarter of 2005.  Net income for the first six months of 2006 was $5,949,000, which represented a decrease of $255,000, or 4.1%, compared to net income of $6,204,000 for the first half of 2005.  On a weighted average share basis, net income for the first six months of 2006 was $0.47 per diluted share, which represented a decrease of 4.1% from $0.49 per diluted sharefor the first half of 2005.  The decrease in earnings for the first half of 2006 compared to the first half of 2005 was primarily due to an increase of $2,650,000 in the provision for loan losses.  The increase in the provision for loan losses reflected a higher level of charge offs and an increase in loan volume.

          Total loans were $842.0 million at June 30, 2006, which represented an increase of $120.8 million, or 16.8%, from the amount reported as of June 30, 2005 and an increase of $67.1 million, or 8.7% over total loans at December 31, 2005.  Total deposits at June 30, 2006 of $905.3 million increased $100.8 million, or 12.5%, from $804.5 million at June 30, 2005 and increased $26.5 million, or 3.0%, from $878.8 million at December 31, 2005.  Compared to the second quarter of 2005, we experienced growth in every category of deposits during the second quarter of 2006.  Shareholders’ equity was $84.3 million at June 30, 2006, an increase of $6.7 million, or 8.6%, compared to shareholders’ equity of $77.6 million at June 30, 2006.  See the Statement of Changes in Shareholders’ Equity for a detail of the changes.

          The following table shows selected performance ratios for the first six months of 2006 and 2005 that management believes to be key indicators of our performance:

|                                                            |   | **Six Months   Ended** |   |
|-----------------------------------------------------------------|--------|------------------------|--------|
|                                                            |   |                        |   |
|                                                            |   | **June 30,   2006**    |   | **June 30,   2005** |   |
|                                                            |   |                        |        |   |  |  |   |
| Annualized   Return on Average Assets (ROAA)                    |   |                   | 1.06   | % |   | 1.25 | % |
| Annualized   Return on Average Shareholders’ Equity (ROAE) |   |                   | 14.39  |   |   | 16.44 |   |
| Shareholders’   Equity to Assets - Average                 |   |                   | 7.39   |   |   | 7.61 |   |
| Dividend   Payout Ratio                                         |   |                   | 33.64  |   |   | 27.95 |   |
| Net   Interest Margin (tax equivalent)                          |   |                   | 4.72   |   |   | 4.52 |   |
| Efficiency   Ratio                                              |   |                   | 56.77  |   |   | 59.37 |   |
| Net   Income Per Share - Diluted                                |   | $                      | 0.47   |   | $ | 0.49 |   |

          The return on average assets ratio is calculated by dividing annualized net income by average total assets for the period.  Our return on average assets ratio was 1.06% for the first six months of 2006 compared with the average return on average assets ratio of 1.34% for the first six months of 2006 for other financial institutions in our peer group.  Our peer group is comprised of six (6) other publicly traded bank holding companies headquartered in Texas with assets ranging from $11.5 billion to $2.7 billion and was selected by our management.  Our return on average assets for the first six months of 2006 was negatively affected by the level of the provision for loan losses.

          The return on average shareholders’ equity ratio is calculated by dividing annualized net income by average shareholders’ equity for the period.  Our return on average shareholders’ equity ratio was 14.39% in the first six months of 2006 compared with the average return on average shareholders’ equity ratio of 13.75% for the same period for the other financial institutions in our peer group.  

          The shareholders’ equity to assets ratio is calculated by dividing average shareholders’ equity by average total assets for the period.  Our shareholders’ equity to assets ratio was 7.39% in the first six months of 2006 compared with the average shareholders’ equity to asset ratio of 9.72% for the first six months of 2006 of the other financial institutions in our peer group.   

          The dividend payout ratio is determined by dividing the total dividends paid by net income for the period.  For the first six months of 2006, our dividend payout ratio resulted in a yield-to-market price return that compared favorably to our peer group.

          Net interest margin is calculated by dividing annualized net interest income on a tax equivalent basis by average total earning assets.  Management believes our net interest margin of 4.72% in the first six months of 2006 compares favorably to the net interest margin ratio of other financial institutions in our peer group, which averaged 4.21% in the first six months of 2006.

          The efficiency ratio is calculated by dividing non-interest expenses by the sum of total non-interest income and tax equivalent interest income for the period.  The efficiency ratio provides a measure of the extent to which our revenues are absorbed by our non-interest expenses.  Management believes our efficiency ratio of 56.77% in the first six months of 2006 compares favorably to the average efficiency ratio of other financial institutions in our peer group, which was 56.66% in the first six months of 2006.

Net Interest Income

          The net interest margin was 4.76% for the second quarter of 2006, which represented an increase of 19 basis points from the second quarter of 2005.  This increase in net interest margin reflected a 97 basis point increase in yield on earning assets from the second quarter of 2005 to the second quarter of 2006, which was partially offset by a 103 basis point increase in rates paid on interest-bearing liabilities from the second quarter of 2005 to the second quarter of 2006.  The increase in the net interest margin also reflected the impact of our non-interest bearing funding sources, primarily demand deposits and shareholders’ equity.  Average demand deposits were $258.1 million in the second quarter of 2006, an increase of $19.0 million, or 7.9%, over the second quarter of 2005.

          Net interest income (tax equivalent) for the second quarter of 2006 was $12,741,000, which represented an increase of $1,981,000, or 18.4%, compared to the second quarter of 2005.  In the second quarter of 2006, tax equivalent interest income increased $4,564,000, or 31.7%, while interest expense increased $2,583,000, or 70.7%, compared to the second quarter of 2005.  The  increase in net interest income resulted from a 13.6% growth in average earning assets for the second quarter of 2006 compared to the second quarter of 2005, along with a 200 basis point increase in market interest rates (as measured by the prime rate as published in the *Wall Street Journal)* from June 2005 through June 2006.

          The net interest margin was 4.72% for the six months ended June 30, 2006 which represented a 20 basis point increase over the net interest margin of 4.52% for the six months ended June 30, 2005.  The increase in net interest margin reflected a 98 basis point increase in yield on earning assets from the first six months of 2005 to the first half of 2006, which was partially offset by a 103 basis point increase in rates paid on interest-bearing liabilities from the first six months of 2005 to the first half of 2006.  The increase in net interest margin also reflected an increase in the volume of loans, up $96.7 million, or 13.5%, over the first six months of 2005 and increases in non-interest bearing funding sources, such as demand deposits and shareholders’ equity.   Average demand deposits were $254.6 million in the first half of 2006, an increase of $22.2 million, or 9.6%,over the first half of 2005.

          Net interest income (tax equivalent) for the first six months of 2006 was $24,847,000, which represented an increase of $3,818,000, or 18.2%, compared to the first six months of 2005.  In the first half of 2006, tax equivalent interest income increased $8,777,000, or 31.5%, while interest expense increased $4,959,000, or 73.0% compared to the first half of 2005.  The increase in net interest income reflected a 13.0% increase in average earning assets for the first six months of 2006 compared to the first six months of 2005 and the higher interest rate environment. 

          In the event that our average loans continue to increase and we are unable to fund such growth solely through the generation of additional deposits, we may be required to obtain additional funding from secondary sources, such as the Federal Home Loan Bank, Federal Funds purchased, or brokered deposits, which could have a negative impact on our net interest margin.  Therefore, we may experience a slower growth in our net interest margin during the remainder of 2006 as a result of any such borrowings, but should benefit as our investment portfolio and maturing fixed rate loans reprice at higher rates.  Because of the composition of our balance sheet and our emphasis on commercial lending, we are market interest rate sensitive and expect to benefit from any market interest rate increases, assuming that interest rates on deposits and borrowings do not increase significantly faster than interestrates on earning assets.

          The table below analyzes the increase in net interest income on a fully tax equivalent basis for the three month periods ended June 30, 2006 and 2005.  Non-accruing loans have been included in assets for these computations, thereby reducing yields on total loans.  For purposes of this table, changes attributable to both rate and volume which cannot be segregated have been allocated to rate.

Non-Interest Income

          The major component of non-interest income is various charges and fees that we earn on deposit accounts and related services.  The following table reflects the changes in non-interest income during the periods presented (dollars in thousands):

          Non-interest income was $2.2 million for the second quarter of 2006, an increase of $161,000, or 7.9%, over the second quarter of 2005.  Non-interest income was $4.1 million for the six months ended June 30, 2006, an increase of $154,000, or 3.9%, over the second half of 2005.

          Service charges on deposit accounts were relatively flat for the quarter and six month periods ended June 30, 2006 compared to same periods in the prior year.  Reductions in the fees earned on commercial accounts that are on account analysis were somewhat offset by increases in insufficient funds charges. The decrease in account analysis income reflects the impact of the higher interest rate environment on earnings credits for commercial deposit account balances.

          The non-recurring income for the first six months of 2005 resulted from an extraordinary payment from PULSE EFT as a participant in that ATM network.              

          The increase in other non-interest income in the second quarter and first half of 2006, as compared to the same periods last year, is largely due to increases in investment services fees, mortgage loan origination fees, debit card income and insurance commissions.    

Non-interest Expense

          Non-interest expense includes all expenses other than interest expense, the provision for loan losses and income tax expense.  The following table summarizes the changes in non-interest expense during the periods presented (dollars in thousands):

          Total non-interest expense increased 9.6% in the second quarter of 2006 over the second quarter of 2005.  As a percent of average assets, non-interest expense was 2.92% in the second quarter of 2006 (annualized) compared with 3.01% in the same period last year.  Total non-interest expense for the first six months of 2006 was 10.9% higher than the first half of last year.  As a percent of average assets, non-interest expense was 2.94% of average assets (annualized) for the six months ended June 30, 2006, compared with 2.99% in the first half of 2005. 

          The “efficiency ratio” (non-interest expenses divided by total non-interest income plus net interest income) was 55.46% for the second quarter of 2006 compared to 59.07% for the second quarter of 2005.  

          The increases in salaries and benefits during the second quarter of 2006 and the first six months of 2006 compared to the same periods in 2005 were due to salary merit increases, increases in the cost of employee benefit programs, expenses associated with Summit Financial Partners and the recognition of expense related to employee stock options.  Effective January 1, 2006, the Corporation adopted the fair value recognition provisions of SFAS No. 123R, “Share-Based Payment” using a modified version of prospective application.  Under this method, compensation expense will be recorded for all awards granted after the date of adoption and for the unvested portion of previously granted awards that were outstanding as of the beginning of the period of adoption.  For the three month and six month periods ended June 30, 2006, stock-based compensation expense was $58,000 and $102,000,respectively.  For periods prior to January 1, 2006, stock based compensation has been included in pro forma disclosures in the financial statement footnotes.

          The higher levels of occupancy expense for the second quarter and first half of 2006 compared to the same periods of 2005 year were due to several factors, including increases in rent expense, utilities and ad valorem taxes.  Also contributing to the increase in occupancy expense was the loss of tenant rents at a bank-owned facility beginning in September 2005.

          The increases in insurance expense during the second quarter and first half of 2006 were largely attributable to higher costs of blanket bond and directors and officers liability policies.  

          The increases in data and item processing expense during the second quarter and first half of 2006 were largely attributable to higher costs related to the Corporation’s internet banking product. 

Allowance for Loan Losses and Non-Performing Assets

          The allowance for loan losses was $9,958,000, or 1.18% of total loans, as of June 30, 2006 compared to $10,798,000, or 1.50% of total loans, as of June 30, 2005.   The provision for loan losses was $3,100,000 for the first six of 2006 compared with $450,000 for the same period last year.  For the six months ended June 30, 2006 and 2005, net charge-offs (recoveries) were  0.05% and (0.02)% of average loans, respectively, not annualized. 

          Transactions in the provision for loan losses are summarized as follows (in thousands):

          The increase in the provision for loan losses for the quarter and six month period ended June 30, 2006 reflected an increase in charge offs, a higher level of non-accrual loans and the increase in loan volume.  Net loan charge offs were $4.2 million for the second quarter of 2006 compared with net recoveries of $54,000 for the same period last year.  Non-accrual loans were $6.1 million at June 30, 2006, an increase of $2.7 million, or 79.7%, from June 30, 2005, and an increase of $3.1 million, or 101.9%, from December 31, 2005.

          We reported in a filing on Form 8-K in February 2006 that our largest classified borrower had experienced further deterioration in its financial condition and had requested a standstill agreement until June 30, 2006.  All loans to this borrower were placed on non-accrual status in February 2006 with an agreement, subject to an infusion of a specified amount of capital and certain other conditions, to defer all payments of principal and interest from this borrower until June 30, 2006.  Also in February 2006, an outside investor contributed to the borrower the specified amount of additional capital in the form of debt subordinated to the Corporation’s loans.

Subsequent to placing the loans to this borrower on non-accrual, the outstanding principal balance was reduced to $6.9 million prior to any charge offs as of June 30, 2006.  Based on our evaluation of collateral value, the borrower’s financial prospects and other considerations, we recorded a charge off of $4.3 million on these credits as of June 30, 2006. Our exposure on these credits was thereby reduced to approximately $2.6 million.  Several options to repay this debt are being explored by the borrower and the Corporation.  In March 2006, we placed loans to a second borrower on non-accrual based on deterioration in that borrower’s financial condition.  The loans to the second borrower had a combined balance of approximately $2.1 million as of June 30, 2006.  The borrower is in the process of selling assets to reduce the debt.   The Corporation’s management intends to continue tomonitor these credits very closely.

          As of June 30, 2006, the allowance for loan losses as a percentage of non-accrual loans was 164.4% compared with 373.6% as of December 31, 2005.  Total non-performing assets as a percentage of loans and foreclosed assets was 0.72% at June 30, 2006 compared with 0.39% as of December 31, 2005.

          Loans are graded on a system similar to that used by the banking industry regulators.  The first level of criticized loans is “Other Assets Especially Mentioned” (OAEM).  These loans are fundamentally sound but have potential weaknesses which may, if not corrected, weaken the asset or inadequately protect the bank’s credit position at some future date.  The second level is “Substandard,” which are loans inadequately protected by current sound net worth, paying capacity or pledged collateral of the borrower.  The last level of criticized loans, before they are charged-off, is “Doubtful.”  Doubtful loans are considered to have inherent weaknesses because collection or liquidation in full is highly questionable.  In addition to the above grading system, the Corporation maintains a separate “watch list” which further aids theCorporation in monitoring loan quality.  Watch list loans show warning elements where the present status portrays one or more deficiencies that require attention in the short run or where pertinent ratios of the account have weakened to a point where more frequent monitoring is warranted.  The Corporation remains diligent in its efforts to identify any loan that might reflect weakness of the borrower as soon as possible.  Management is not aware of any potential loan problems that have not been disclosed to which serious doubt exists as to the ability of the borrower to substantially comply with the present repayment terms.

          Totalcriticized loans were $31.6 million at June 30, 2006, a decrease of $3.5 millionand $4.0 million from the levels of December 31, 2005 and June 30, 2005,respectively.   The loan charge-off previously discussed materiallycontributed to the decrease in criticized loans.

Criticized loans as a percentage of total loans were 3.8%, 4.5% and 4.9% as of June 30, 2006, December 31, 2005 and June 30, 2005, respectively. 

Interest Rate Sensitivity

          Interest rate sensitivity is the relationship between changes in market interest rates and net interest income due to the repricing characteristics of assets and liabilities.

          The following table, commonly referred to as a “static GAP report”, indicates the interest rate sensitivity position at June 30, 2006 and may not be reflective of positions in subsequent periods (dollars in thousands):

          The preceding static GAP report reflects a cumulative liability sensitive position during the one year horizon.  An inherent weakness of this report is that it ignores the relative volatility any one category may have in relation to other categories or market rates in general.  For instance, the rate paid on NOW accounts typically moves slower than the three month T-Bill.  Management attempts to capture this relative volatility by utilizing a simulation model with a “beta factor” adjustment which estimates the volatility of rate sensitive assets and/or liabilities in relation to other market rates.

          Beta factors are an estimation of the long term, multiple interest rate environment relation between an individual account and market rates in general.  For instance, NOW, savings and money market accounts, which are repriceable within 30 days, will have considerably lower beta factors than variable rate loans and most investment categories.  Taking this into consideration, it is quite possible for a bank with a negative cumulative GAP to total asset ratio to have a positive “beta adjusted” GAP risk position.  As a result of applying the beta factors established by management to the earning assets and interest bearing liabilities in the static gap report via a simulation model, the negative cumulative GAP to total assets ratio at one year of (13.27%) was reversed to a positive 16.99%  “beta adjusted” GAP position.  Management feels that the “betaadjusted” GAP risk technique more accurately reflects the Corporation’s GAP position.

Capital

          At June 30, 2006, shareholders’ equity totaled $84.3 million, an increase of $2.9 million, or 3.6%, compared to December 31, 2005, and an increase of $6.7 million, or 8.6%, compared to June 30, 2005.  This increase reflects the increase in retained earnings which was partially offset by the payment of dividends, the increase in the unrealized loss on available-for-sale investment securities and the impact of the purchase of treasury stock.  The unrealized loss, net of tax benefit, on available-for-sale investment securities increased $1.7 million in the six months ended June 30, 2006.

          On April 18, 2006, the Board of Directors of the Corporation approved a stock purchase plan (the “2006 Stock Purchase Plan”) authorizing management to purchase up to 623,675 shares of the Corporation’s common stock on behalf of the Corporation over the twelve-month period beginning April 19, 2006 and ending on April 18, 2007, including in open market transactions, privately negotiated transactions or other transactions in accordance with all applicable state and federal laws and regulations.  In the quarter ended June 30, 2006, 29,200 shares were purchased by the Corporation pursuant to the 2006 Stock Purchase Plan in privately negotiated transactions.  

          The Corporation’s ability to purchase shares of the Corporation’s common stock is subject to various banking laws, regulations and policies as well as rules and regulations of the Securities and Exchange Commission.  

          We and the Bank are subject to capital adequacy guidelines established by the Federal Reserve Board and other regulatory authorities.  The table below illustrates the Bank’s and our compliance with the capital adequacy guidelines as of June 30, 2006 and 2005 (dollars in thousands):

          As of June 30, 2006, the Bank exceeded the risk-based capital and leverage requirements set by regulatory authorities and satisfied the criteria for classification as a “well capitalized” institution under the rules of the Federal Deposit Insurance Corporation Improvement Act of 1991.

Liquidity

          Our primary “internal” sources of liquidity consist of the federal funds that we sell and our portfolio of marketable investment securities, particularly those with shorter maturities.  Federal funds sold and investment securities maturing within 90 days represented $14.0 million, or 1.20%, of total assets as of June 30, 2006.  Additionally, our ability to sell loan participations, purchase federal funds and obtain advances from the Federal Home Loan Bank serve as secondary sources of liquidity.  The Bank has approved federal funds lines at other banks.

          Our liquidity is enhanced by the fact that 85.5% of our total deposits at June 30, 2006 were “core” deposits.   Core deposits are defined as total deposits less public funds, brokered deposits and certificates of deposit greater than $100,000.   Core deposits are generally more stable (i.e., less likely to be withdrawn) than other deposits.  Additionally interest-bearing core deposits may have lower interest rates than other interest-bearing deposits.  Our loan to deposit ratio averaged 92.6% for the six month period ended June 30, 2006.

          In the event that our average loans continue to grow during 2006 and we are unable to fund any such growth solely through the generation of additional deposits, we may be required to obtain funding from secondary sources, including purchasing federal funds, obtaining advances from the Federal Home Loan Bank or other secondary sources.  In such an event, our business, results of operations and financial condition could be negatively impacted.  

          Our income, which provides funds for the payment of dividends to our shareholders and for other corporate purposes, is derived from our investment in the Bank.

          On May 3, 2004, the Corporation formed SBI Trust and SBI Trust subsequently issued $12.0 million of floating rate (three month LIBOR plus a margin of 2.65%) Capital Securities (the “Trust Capital Securities”).  Concurrent with the issuance of the Trust Capital Securities, SBI Trust issued trust common securities to the Corporation in the aggregate liquidation value of $372,000.  The proceeds of the issuance of the Trust Capital Securities and trust common securities were invested in the Corporation’s Floating Rate Junior Subordinated Deferrable Debentures (the “Deferrable Debentures”), which mature on July 7, 2034 and have a call feature that permits the Corporation to redeem any or all of the securities after July 7, 2009.  The interest rate on the Deferrable Debentures at June 30, 2006 was 7.72%.  The Deferrable Debentures, which are the only asset of SBITrust, are subordinated and junior in right of payment to all present and future senior indebtedness (as defined in the Indenture dated May 3, 2004) of the Corporation.

32

          On September 15, 2005, we obtained a line of credit from a bank under which we may borrow $10,000,000 at a floating rate (three month LIBOR plus a margin of 2.00%).  The line of credit is secured by stock of the Bank and matures on September 15, 2006, whereupon, if balances are outstanding, the line converts to a term note having a five year term.  The Corporation will not pay a fee for any unused portion of this line.  At June 30, 2006, there were no amounts outstanding under the line.   The purpose of the line is to provide an additional liquidity source.

Off-Balance-Sheet Arrangements, Commitments, Guarantees and Contractual Obligations

          Except as set forth herein, during the six months ended June 30, 2006, there have been no material changes outside the ordinary course of the Corporation’s business in the contractual obligations specified in “Item 7: Management’s Discussion and Analysis of Financial Condition and Results of Operations – Off-Balance-Sheet Arrangements, Commitments, Guarantees and Contractual Obligations” in our Annual Report on Form 10-K for the year ended December 31, 2005.

          At June 30, 2006, outstanding documentary and standby letters of credit totaled $7,311,000 and commitments to extend credit totaled $230,352,000.  Documentary and standby letters of credit and commitments to extend credit totaled $6,637,000 and $227,031,000 at December 31, 2005.  The increase in commitments to extend credit reflects the continued demand for credit facilities in our market.

Related Party Transactions

          The Bank has made loan transactions in the ordinary course of business with certain of its and the Corporation’s officers, directors and their affiliates. All loans included in such transactions are made on substantially the same terms, including interest rate and collateral, as those prevailing at the time for comparable transactions with other unrelated persons and all such loans are current as to principal and interest payments.  Total loans outstanding to such related parties amounted to approximately $8,108,000 at June 30, 2006 and $9,356,000 at December 31, 2005.

Subsequent Events

          On July 2, 2006, the Corporation and Cullen/Frost Bankers, Inc., a Texas corporation (“Cullen/Frost”), entered into an Agreement and Plan of Merger (the “Agreement”) pursuant to which the Corporation will merge with and into Cullen/Frost. Under the terms of the Agreement, the Corporation’s shareholders will have the right, subject to pro-ration, to elect to receive cash, shares of Cullen/Frost common stock or a combination thereof having a value equal to $11.50 plus 0.2933 Cullen/Frost shares. The total consideration consists of approximately $143.4 million in cash and approximately 3.84 million shares of Cullen/Frost common stock (assuming the treasury stock method of accounting for options before giving effect to any exercises of outstanding options). The transaction is subject to customary closing conditions, including the receipt of regulatory approvals andapproval of the shareholders of the Corporation. The merger is currently expected to be completed in the fourth quarter of 2006, although delays could occur. 

          The foregoing summary of the Agreement is not complete and is qualified in its entirety by reference to the complete text of such document, which is filed as Exhibit 2.1 to the Report on Form 8-K filed with the Securities and Exchange Commission on July 3, 2006 and  which is incorporated herein by reference. 

          On July 18, 2006, the Board of Directors of the Corporation approved a quarterly dividend of $.08 per share to be paid on August 15, 2006 to shareholders of record on August 7, 2006.  

Critical Accounting Policies

          Our accounting policies are fundamental to understanding management’s discussion and analysis of results of operations and financial condition.  We have identified our policy with respect to allowance for loan losses as critical because it requires management to make particularly difficult, subjective or complex judgments about matters that are inherently uncertain and because of the likelihood that materially different amounts would be reported under different conditions or using different assumptions.   We, in consultation with our Audit Committee of the Board of Directors, have reviewed and approved this critical accounting policy, which is further described under the caption “Loan and Allowance for Loan Losses” in Note 1 (“Summary of Significant Accounting Policies”) to the Financial Statements.

          These evaluations are inherently subjective because, even though they are based on objective data, it is management’s interpretation of that data that determines the amount of the appropriate allowance.  Therefore, from time to time (but at least quarterly), management reviews the actual performance and write-off history of the loan portfolio and compares that to previously determined allowance coverage percentages.  In this manner, management evaluates the impact the previously mentioned variables may have had on the loan portfolio to determine which changes, if any, should be made to the assumptions and analyses.  Recent analysis has indicated that projections of estimated losses inherent in the loan portfolio have approximated actual write-off experience during the current economic environment.  

          Actual results could differ materially from estimates as a result of changes in economic or market conditions and other factors.  Changes in our evaluations and the assumptions underlying these evaluations could result in a material change in the allowance.

33

While we believe that the allowance for loan losses has been established and maintained at levels adequate to reflect the risks inherent in the loan portfolio, future increases may be necessary if economic or market conditions and other factors differ substantially from the conditions that existed at the time of the initial determination.

          The Corporation adopted FAS No. 123R, “Share-Based Payments,” effective January 1, 2006, utilizing the “modified prospective” method as described in the standard. Under the “modified prospective” method, compensation cost is recognized for all share-based payments granted after the effective date and for all unvested awards granted prior to the effective date. Prior to adoption, the Corporation accounted for stock-based compensation under the recognition and measurement principles of Accounting  Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees,” and related interpretations. The Corporation recognized $102,000 in total stock-based compensation expense during the first half of 2006. 

          There have been no significant changes in critical accounting policies or management estimates since the year ended December 31, 2005 other than the adoption of FAS No. 123R as described above. A comprehensive discussion of the Company’s critical accounting policies and management estimates is included in Management’s Discussion and Analysis of Financial Condition and Results of Operations in the Company’s Annual Report on Form 10-K for the year ended December 31, 2005. 

Item 3 – Quantitative and Qualitative Disclosure about Market Risk

          There were no material changes in market risks faced by the Corporation from December 31, 2005 to June 30, 2006.  For more information regarding quantitative and qualitative disclosures about market risk, please refer to the Corporation’s Annual Report on Form 10-K as of and for the year ended December 31, 2005, and in particular, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Interest Rate Sensitivity and Liquidity.”

Item 4 – Controls and Procedures

          The Corporation’s management, including the Corporation’s principal executive officer and principal financial officer, has evaluated the effectiveness of the Corporation’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of the end of the Corporation’s fiscal quarter ended June 30, 2006.  Based on that evaluation, the Corporation’s principal executive officer and principal financial officer have concluded that the Corporation’s disclosure controls and procedures were effective as of the end of the Corporation’s fiscal quarter ended June 30, 2006.

          There were no changes in the Corporation’s internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Rule 13a-15 or Rule 15d-15 under the Exchange Act that occurred during the Corporation’s fiscal quarter ended June 30, 2006 that have materially affected, or are reasonably likely to materially affect, the Corporation’s internal control over financial reporting.

**Risks Associated with our Pending Merger with Cullen/Frost Bancshares, Inc. (‘Cullen/Frost”)**

Failure to complete the pending merger with Cullen/Frost could materially and adversely affect our stock price and our results of operations. 

          On July 2, 2006, we entered into an Agreement and Plan of Merger with Cullen/Frost whereby we would merge with and into Cullen/Frost. Completion of the merger is subject to certain conditions, including approval by our holders of common stock, regulatory approvals, and various other closing conditions. We cannot assure you that these conditions will be met or waived, that the necessary approvals will be obtained or that we will be able to successfully consummate the merger as currently contemplated under the merger agreement or at all. If the merger is not completed:

| • | we   may experience a negative reaction to the termination of the merger from our   customers, employees or affiliates which may adversely impact our future   results of operations as a stand-alone entity.    |

          The occurrence of any of these events individually or in combination could have a material adverse effect on our financial condition, results of operations and our stock price. In addition, if the merger agreement is terminated and our board of directors seeks another merger or business combination, we may not be able to find a party willing to pay a price equal to or more attractive than the price Cullen/Frost has agreed to pay. 

**Fluctuations in market prices of Cullen/Frost common stock will affect the value that our shareholders receive for their shares of our common stock.**

          Upon completion of the merger, shares of our common stock (other than any dissenting shares) will be converted into shares of Cullen/Frost common stock and cash. While the merger consideration has been generally structured to provide that our shareholders will receive, for each of their shares of common stock , 0.2933 shares of Cullen/Frost common stock and $11.50 in cash, in the event the average share price of Cullen/Frost common stock during the 15 consecutive trading days ending on and including the date of receipt of the last requisite regulatory approval falls below $45.95, Cullen/Frost has the discretion, but not the obligation, to increase either the exchange ratio with respect to the number of shares of Cullen/Frost common stock that our shareholders will receive, the per share cash consideration or a combination of both. Because the price of Cullen/Frost common stock will fluctuate prior to themerger, Cullen/Frost cannot assure our shareholders of the market value or number of the shares of Cullen/Frost common stock or of the amount of cash that they will receive in the merger. 

          The price of Cullen/Frost common stock may vary from its price on the date the proxy statement/prospectus is sent to our shareholders, the date of our special meeting of shareholders and the date for determining the average trading price discussed elsewhere. Stock price fluctuations may result from a variety of factors, some of which are beyond the control of Cullen/Frost, including, among other things, changes in Cullen/Frost’s businesses, operations and prospects, regulatory considerations and general market and economic conditions. Because the date the merger is to be completed will be later than the date of the special meeting, the price of the Cullen/Frost common stock on the date of the special meeting may not be indicative of its price on the date the merger is to be completed. 

**If the price of Cullen/Frost common stock falls and the decrease exceeds certain pre-agreed levels, and if Cullen/Frost does not elect to alter the exchange ratio to provide more shares and/or alter the amount of the per share cash consideration to provide more cash, we have the right to terminate the merger agreement and the merger will not occur.**

**Cullen/Frost may have difficulty combining our operations with its own operations or realizing the anticipated benefits of the merger.**

          Because the markets and industries in which we and Cullen/Frost operate are highly competitive, and due to the inherent uncertainties associated with the integration of acquired companies, Cullen/Frost may not be able to integrate our operations without encountering difficulties, including, without limitation, the loss of key employees and customers, the disruption of their respective ongoing businesses and possible inconsistencies in standards, controls and procedures. We expect the merger to result in certain benefits for the combined company, such as cost savings and other financial and operational benefits. We cannot assure you, however, when, if ever, or to the extent to which the combined company will be able to realize these benefits. Difficulties associated with integrating the two companies could have a material adverse effect on the combined company and the market price of the Cullen/Frostcommon stock.

          There have been no other material changes from the risk factors previously disclosed in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2005 in response to Item 1A. to Part I of Form 10-K.
