SUMMIT BANCSHARES, INC. AND SUBSIDIARIES FOR THE THREE MONTHS ENDED MARCH 31, 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 three months of 2006, the average cash balance maintained at the Federal Reserve Bank was $3,345,000. Compensating balances held at correspondent banks, to minimize service charges, averaged approximately $24,901,000 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 in
earnings.  Investments not classified as either held-to-maturity or trading are classified as available-for-sale and measured at fair value in the financial statements with unrealized gains and losses reported, net of tax, in a separate component of shareholders equity until realized.

The 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 until the 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 March 31, 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).

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 $82,000, $328,000 and $82,000 for the three months ended March 31, 2006, the year ended December 31, 2005 and the three months ended March 31, 2005, respectively.

The Corporation has available a line of credit with the FHLB of Dallas which allows it to borrow on a collateralized basis at a fixed term.  The borrowings are collateralized by a blanket floating lien on certain real estate loans, the FHLB capital stock owned by the Corporation and any funds on deposit with FHLB.  At March 31, 2006, the Corporation had $50.0 million of borrowings outstanding under the line of credit at a rate of 3.77%, $35.0 million of which matures in 2006 and the remaining $15.0 million of which matures in 2007.  At March 31, 2006, the Corporation had average borrowings under the line of credit of $56.7 million.  For the three months ended March 31, 2005, the Corporation had $60.0 million of borrowings outstanding under the line of credit at a rate of 2.50%, $30.0 million of which matured in 2005.  At December 31, 2005, $55.0 million of borrowings were
outstanding at an average rate of 3.44%.  For the year ended December 31, 2005, the Corporation had average borrowings of $61.8 million.

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 March 31, 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 March 31, 2006 and December 31, 2005 was 7.25% and 6.80%, respectively.  The Deferrable
Debentures, 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 three months ended March 31, 2006, stock-based compensation expense was $44,000.  The following table illustrates the effect on net income and earnings per share if the Corporation had applied the fair value recognition provisions of SFAS 123R to stock based compensation for the three months ended March 31, 2005 (in thousands, except for per share data):

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 $10,369,000 at March 31, 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 March 31, 2006, outstanding documentary and standby letters of credit totaled $8,607,000 and commitments to extend credit totaled $231,880,000.

In addition, the Corporation leases certain office facilities under operating leases.  Rent expense for all operating leases totaled $356,000 and $297,000 for the three months ended March 31, 2006 and 2005, respectively, and $1,305,000 for the year ended December 31, 2005.

NOTE 17 - Stock Option Plans

The Corporation has two Incentive Stock Option Plans, the 1993 Plan and the 1997 Plan, (each, a Plan, and, collectively, the Plans).  No more options may be granted under the 1993 Plan.  The 1997 Plan has reserved 1,200,000 shares (adjusted for two-for-one stock splits in 1997 and 2004) of common stock for grants thereunder.  The Plans provide for the granting to executive management and other key employees of the Corporation and its subsidiaries incentive stock options, as defined under the current tax law.  The options granted under the Plans will be exercisable for ten years from the date of grant and generally vest ratably over a five year period.  Options will be and 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:

|                                               |  | Shares   Under Option Plans           |

Options outstanding at March 31, 2006 have exercise prices between $5.19 to 18.75 per share with a weighted average exercise price of $10.02 and 497,099 shares exercisable.  At March 31, 2006, there remained 501,596 shares reserved for future grants of options under the 1997 Plan.  See Note 12 Stock Based Compensation for information regarding the dilutive impact of these stock options.

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 Plan.  The 2006 Plan 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 certain
adjustments, 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 predecessor Plans.

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 participants deferrals of compensation up to 100% of the employee contributions.

The amount expensed in support of the plan was $188,000 and $146,000 during the first three 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 $125,000 and $72,000 for the first three 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 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):

The incremental shares for the assumed exercise of the outstanding options were determined by application of the treasury stock method.

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):

|                                                                      |  | March 31, |        
|--------------------------------------------------------------------- |  | --------- | -------

|                                                                      |  | 2006      |        
|                                                                      |  |           |        
|Financial   Instruments Whose Contract Amounts Represent Credit Risk: |  |           |        
|Loan Commitments Including Unfunded Lines of   Credit                 |  | $         | 231,880
|Letters of Credit                                                     |  |           | 8,607  

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.

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 is not expected to materially adversely affect the Corporations financial position.

NOTE 23 - Stock Repurchase Plan

On April 19, 2005, the Board of Directors of the Corporation approved a stock repurchase plan (the 2005 Stock Purchase Plan) authorizing management to purchase up to 620,467 shares of the Corporations common stock on behalf of the Corporation over the twelve-month period beginning April 19, 2005 and ending on April 18, 2006, 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 March 31, 2006, 10,000 shares were purchased by the Corporation pursuant to the 2005 Stock Purchase Plan in privately negotiated transactions.  12,378 shares of the Corporations common stock, in the aggregate, were purchased by the Corporation pursuant to the 2005 Stock Purchase Plan from the period beginning April 19, 2005 through April 18, 2006.  No more shares may be purchased pursuant to the 2005 Stock Purchase 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.

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.  The Corporation anticipates purchasing shares of the Corporations common stock pursuant to the 2006 Stock Purchase Plan as conditions warrant.

NOTE 24 - Subsequent Events

On April 18, 2006, the Board of Directors of the Corporation approved a quarterly dividend of $.08 per share to be paid on May 15, 2006 to shareholders of record on April 28, 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.

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 Plan.  The 2006 Plan 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 certain adjustments, 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 predecessor Plans.

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.                                                                                                                                                                                                                                                                            
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| |                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
| | 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 March 31, 2006, the Bank
can legally initiate dividend payments of $13,599,000 for the remainder of
2006.  The Bank is also restricted from paying dividends that would

Item 2 - Managements Discussion and Analysis of Financial Condition and Results of Operations

The following
discussion should be read in conjunction with the consolidated financial
statements, accompanying notes and selected financial data appearing elsewhere
in this Quarterly Report on Form 10-Q and in our most recent Annual Report on
Form 10-K and may contain certain forward-looking statements that are based on
current management expectations.  Generally, verbs in the future tense and
the words believe, expect, anticipate,
estimate, intends, opinion,
potential and similar expressions identify forward-looking
statements.  Examples of this forward-looking information can be found in,
but are not limited to, the expected effects of accounting pronouncements and
government regulation applicable to our operations, the discussion of allowance
for loan losses, and quantitative and qualitative disclosure about market
risk.  Our actual results could differ materially from the forward-looking
statements and management expectations.  Further information concerning our
business, including additional risk factors and uncertainties that could cause
actual results to differ materially from the forward-looking statements
contained in this Quarterly Report on Form 10-Q, are set forth below under the
heading Risk Factors.  These risk factors and uncertainties
should be considered in evaluating forward-looking statements and undue reliance
should not be placed on such statements.  The forward-looking statements
contained herein speak only as of the date of this Quarterly Report on Form 10-Q
and, except as may be required by applicable law and regulation, we do not
undertake, and specifically disclaim any obligation to, publicly update or
revise such statements to reflect events or circumstances after the date of such
statements or to reflect the occurrence of anticipated or unanticipated
events.  Except as the context otherwise requires, references herein to
the Corporation, we, or our refer to the
business of Summit Bancshares, Inc. and its consolidated
subsidiaries.

Overview

Our business has been conducted primarily through our wholly-owned subsidiaries, Summit Bank, National Association (the Bank), Summit Delaware Financial Corporation and SIA Insurance Agency, Inc. (SIA).  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
first quarter of 2006 decreased $587,000, or 19.5%, to $2,426,000 from
$3,013,000 recorded for the first quarter of 2005.  On a weighted average
share basis, net income for the first quarter of 2006 was $0.19 per diluted
share as compared to $0.24 per diluted share for the first quarter of 2005, a
decrease of 20.8%.  The decrease in earnings during the first quarter of
2006 from the first three months of 2005 was primarily due to an increase of
$1,775,000 in the provision for loan losses.  The increase in the provision
for loan losses reflected a higher level of loans on nonaccrual status. 
Nonaccrual loans were $11,164,000 as of March 31, 2006, an increase of
$7,870,000 from the amount reported as of March 31, 2005 and an increase of
$8,164,000 from the amount reported as of December 31, 2005.

Total loans at March 31, 2006 were $808.6 million, which represented an increase of $91.9 million, or 12.8%, over total loans at March 31, 2005 and an increase of $33.7 million, or 4.4% over total loans at December 31, 2005.  Total deposits at March 31, 2006 of $889.9 million increased $92.3 million, or 11.6%, from $797.6 million at March 31, 2005 and increased $11.1 million, or 1.3%, from $878.8 million at December 31, 2005.  Compared to the first quarter of 2005, we experienced growth in every category of deposits during the first quarter of 2006, except for savings accounts.  Shareholders equity was $82.3 million at March 31, 2006, an increase of $7.9 million, or 10.6%, compared to shareholders equity of $74.4 million at March 31, 2005.   See the Statement of Changes in Shareholders Equity on page 5 for a detail of the changes.

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

|                                                           |  | Three   Months Ended |

|                                                           |  | March 31,   2006     |      
|                                                           |  |                      |      
|Annualized Return on   Average Assets (ROAA)               |  |                      | 0.88 
|Annualized Return on   Average Shareholders Equity (ROAE) |  |                      | 11.91
|Shareholders Equity to Assets   - Average                 |  |                      | 7.40 
|Dividend Payout Ratio                                      |  |                      | 41.06
|Net Interest Margin (tax   equivalent)                     |  |                      | 4.68 
|Efficiency Ratio                                           |  |                      | 58.20
|Net Income Per Share -   Diluted                           |  | $                    | 0.19 

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 0.88% for the first quarter of 2006 compared with the average return on average assets ratio of 1.45% for the first quarter 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 form $11.3 billion to $2.7 billion and was selected by our management.  Our return on average assets for the first quarter 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 11.91% in the first quarter of 2006 compared with the average return on average shareholders equity ratio of 15.27% for the same period for the other financial institutions in our peer group.  Our return on average shareholders equity for the first quarter of 2006 was also negatively affected by the loan loss provision recorded in the first quarter.

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 7.40% in the first quarter of 2006 compared with the average shareholders equity to asset ratio of 9.49% for the first quarter 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 quarter 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 4.68% in the first quarter of 2006 compares favorably to the net interest margin ratio of other financial institutions in our peer group, which averaged 4.19% in the first quarter 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 58.20% in the first quarter of 2006 compares favorably to the average efficiency ratio of other financial institutions in our peer group, which was 56.80% in the first quarter of 2006.

|(1)     Loan   interest income includes fees and loan volumes include loans on   non-accrual.  The loan fees include   loan origination fees which are considered adjustments to interest income.  These fees aggregated $489,000 and   $390,000 at March 31, 2006 and 2005, respectively.  Related loan origination costs are not separately allocated to   loans, but are charged to non-interest expense.  For the purpose of calculating loan yields, average loan   balances include non-accrual loans with no related interest income.
|(2)     Presented   on tax equivalent basis using a federal income tax rate of 35% for 2006 and   34% for 2005.                                                                                                                                                                                                                                                                                                                                                                                                                             

The net interest margin was 4.68% for the first quarter of 2006, which represented an increase of 21 basis points from the first quarter of 2005.  This increase in net interest margin reflected a 99 basis point increase in yield on earning assets from the first quarter of 2005 to the first quarter of 2006, which was partially offset by a 103 basis point increase in rates paid on interest-bearing liabilities from the first quarter of 2005 to the first 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, in the  higher interest rate environment in the first quarter of 2006.

In the event that
our average loans continue to grow during 2006 and we are unable to fund such
growth solely through the generation of additional deposits, we may be required
to obtain 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 net interest margin during the remainder of 2006 as a result of any
such borrowings, but will 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 interest rates on earning assets.

Net Interest Income

Net interest income (tax equivalent) for the first quarter of 2006 was $12,106,000, which represented an increase of $1,837,000, or 17.9%, compared to the first quarter of 2005.  In the first quarter of 2006, tax equivalent interest income increased $4,213,000, or 31.4%, while interest expense increased $2,376,000, or 75.7%, compared to the first quarter of 2005.  The  increase in net interest income resulted from a 12.4% growth in average earning assets for the first quarter of 2006 compared to the first 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 March 2005 through March 2006.

The table below analyzes the increase in net interest income on a fully tax equivalent basis for the three month periods ended March 31, 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

Non-interest income for the first quarter of 2006 was $1,873,000, which represented a decrease of $7,000, or 0.4%, from  the first quarter of 2005.  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):

|Total   Non-interest Income           |  | $                                | 1,873

The decrease in service charges on deposit accounts during the first quarter of 2006 was largely the result of a reduction in fees earned on commercial accounts that are on account analysis.  The decrease reflects the impact of the higher interest rate environment on earnings credits for commercial deposit account balances.

The non-recurring income for the first three 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 first quarter of 2006, as compared to the same period last year, is primarily due to increases in investment service fees and insurance commissions.  Investment service fees were $236,000 for the first quarter of 2006 compared with $107,000 for the first quarter of 2005.  The increase in investment services fees is attributable to the operation of Summit Financial Partners, our financial planning and asset management division.  Insurance commissions through SIA were $59,000 for the first quarter, up from $25,000 for the comparable period last year.

Non-interest Expense

Non-interest expenses include 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 12.2% in the first quarter of 2006 over the first quarter of 2005, reflecting increases primarily in salaries and benefits, occupancy,  business development expenses, and insurance expense.  As a percent of average assets, non-interest expenses were 2.95% in the first quarter of 2006 (annualized) and 2.96% for the same period of 2005.

The efficiency ratio (non-interest expenses divided by total non-interest income plus net interest income) was 58.20% for the first quarter of 2006 compared to 59.69% for the first quarter of 2005.

The increase in
salaries and benefits during the first quarter of 2006 compared to the prior
year period was 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 months ended March 31, 2006,
stock-based compensation expense was $44,000.  For periods prior to January
1, 2006, stock based compensation has been included in pro forma disclosures in the financial statement footnotes.

The increase of
$206,000 in occupancy expense for the first quarter of 2006 compared to the same
period of the prior year was 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.

Business development
expenses increased $32,000 in the first quarter of 2006. Contributing to the
increase were higher levels of public relations expenditures and customer
expenses.

Insurance expense was $34,000 higher in the first quarter of 2006. The increase is largely
attributable to higher costs of blanket bond and directors and officers
liability policies.

Legal and professional expenses decreased $93,000 in the first quarter of 2006 compared to the first quarter of 2005 due to lower levels of legal fees and expenses incurred in relation to compliance with the Sarbanes-Oxley Act of 2002 and other corporate governance initiatives.

Allowance for Loan Losses and Non-Performing Assets

The allowance for loan losses was $13,092,000, or 1.62% of total loans, as of March 31, 2006 compared to $10,519,000, or 1.47% of total loans, as of March 31, 2005.   The provision for loan losses was $2,000,000 for the first quarter of 2006 compared with $225,000 for the same period last year.  For the three months ended March 31, 2006 and 2005, net charge-offs (recoveries) were  0.01% and (0.02)% of 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 reflected an increase in non-accrual loans from $3,000,000 at December 31, 2005 to $11,164,000 at March 31, 2006.  We reported in a filing on Form 8-K in February that our largest classified borrower had experienced further deterioration in its financial condition and had requested a deferral of future principal and interest payments until such time as the borrowers financial condition could be restructured, the borrower or certain of its assets sold or other arrangements for payment can be made.  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.  As of March 31, 2006, our exposure on these credits was approximately $7.5 million.  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 $2.2 million as of March 31, 2006.  The ultimate loss, if any, on these two credits cannot be determined at this time, but management thought that it would be prudent to record the additional provision for loan losses.  The Corporations management will continue to monitor these credits very closely.

As of March 31, 2006, the allowance for loan losses as a percentage of non-accrual loans was 117.3% compared with 373.7% as of December 31, 2005.  Total non-performing assets as a percentage of loans and foreclosed assets was 1.43% at March 31, 2006 compared with 0.39% as of December 31, 2005.

As of March 31, 2006, non-accrual loans were comprised of $10,818,000 in commercial loans, $307,000 in real estate mortgage loans and $39,000 in consumer loans.

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 the Corporation
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 exist as to
the ability of the borrower to substantially comply with the present repayment
terms.

Total criticized
loans were $30.7 million at March 31, 2006, a decrease of $4.4 million and $7.4
million from the levels of December 31, 2005, and March 31, 2005, respectively.
Criticized loans as a percentage of total loans were 3.80%, 4.54% and 5.32%
as of March 31, 2006, December 31, 2005, and March 31, 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 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 (10.30%) was reversed to a positive 24.59%  beta adjusted GAP position.  Management feels that the beta
adjusted GAP risk technique more accurately reflects the Corporations GAP position.

Capital

At March 31, 2006,
shareholders equity totaled $82.3 million, an increase of $1.0 million, or
1.2%, compared to December 31, 2005, and an increase of $7.9 million, or 10.6%,
compared to March 31, 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 on
available-for-sale investment securities increased $600 thousand in the three
months ended March 31, 2006.

As of March 31, 2006, the Bank exceeded our 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 $11.0 million, or 1.0%, of total assets as of March 31, 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 86.4% of our total deposits at March 31, 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 92.3% for the three month period ended March 31, 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 March 31, 2006 was 7.25%.  The Deferrable Debentures, which are the only asset of SBI
Trust, are subordinated and junior in right of payment to all present and future senior indebtedness (as defined in the Indenture date May 3, 2004) of the Corporation.

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 March 31, 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 three months ended March 31, 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 March 31, 2006, outstanding documentary and standby letters of credit totaled $8,607,000 and commitments to extend credit totaled $231,880,000.  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 $10,369,000 at March 31, 2006 and $9,356,000 at December 31, 2005.

Subsequent Events

On April 18, 2006, the Board of Directors of the Corporation approved a quarterly dividend of $.08 per share to be paid on May 15, 2006 to shareholders of record on April 28, 2006.

On April 18, 2006, the Board of Directors of the Corporation approved 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, including in open market transactions, privately negotiated transactions or other transactions in accordance with all applicable state and federal laws and regulations.

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 Plan.  The 2006 Plan 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 certain adjustments, 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 predecessor Plans.  As of March 31, 2006, stock option awards
for 566,059 shares of common stock were outstanding.

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 captions
Loan and Allowance for Loan Losses in Note 1 (Summary of
Significant Accounting Policies) to the Financial Statements.

31



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.  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 $44,000 in total stock-based
compensation expense during the first quarter 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 March 31, 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 March 31, 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 March 31, 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 March 31, 2006 that have materially affected, or are reasonably likely to materially affect, the Corporations internal control over financial reporting.
