Notes to Consolidated Financial Statements

(Table amounts are stated in thousands, except for share and per share amounts)

Note 1 - Significant Accounting Policies

Nature of Operations. Cullen/Frost Bankers, Inc. (Cullen/Frost) is a financial holding company and a bank holding company headquartered in San Antonio, Texas that provides, through its subsidiaries, a broad array of products and services throughout numerous Texas markets. In addition to general commercial and consumer banking, other products and services offered include trust and investment management, investment banking, insurance, brokerage, leasing, asset-based lending, treasury management and item processing.

Basis of Presentation. The consolidated financial statements in this Quarterly Report on Form 10-Q include the accounts of Cullen/Frost and all other entities in which Cullen/Frost has a controlling financial interest (collectively referred to as the “Corporation”). All significant intercompany balances and transactions have been eliminated in consolidation. The accounting and financial reporting policies the Corporation follows conform, in all material respects, to accounting principles generally accepted in the United States and to general practices within the financial services industry.

The consolidated financial statements in this Quarterly Report on Form 10-Q have not been audited by an independent registered public accounting firm, but in the opinion of management, reflect all adjustments necessary for a fair presentation of the Corporation’s financial position and results of operations. All such adjustments were of a normal and recurring nature. The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q adopted by the Securities and Exchange Commission (SEC). Accordingly, the financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements and should be read in conjunction with the Corporation’s consolidated financial statements, and notes thereto, for the year ended December 31, 2008, included in the Corporation’s Annual Report on Form 10-K filed with the SEC on February 3, 2009 (the “2008 Form 10-K”). Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period. The Corporation has evaluated subsequent events for potential recognition and/or disclosure through July 22, 2009, the date the consolidated financial statements included in this Quarterly Report on Form 10-Q were issued.

Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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. Actual results could differ from those estimates. The allowance for possible loan losses, the fair value of stock-based compensation awards, the fair values of financial instruments and the status of contingencies are particularly subject to change.

Cash Flow Reporting. Cash paid for interest totaled $48.7 million and $85.1 million during the six months ended June 30, 2009 and 2008. Cash paid for income taxes totaled $52.1 million and $41.4 million during the six months ended June 30, 2009 and 2008. Significant non-cash transactions included $739 thousand of common stock issued to the Corporation’s 401(k) plan in connection with matching contributions during the six months ended June 30, 2009 and transfers of loans to other real estate owned and foreclosed assets in connection with loan foreclosures of $12.4 million and $6.8 million during the six months ended June 30, 2009 and 2008.

Comprehensive Income. Comprehensive income includes all changes in shareholders’ equity during a period, except those resulting from transactions with shareholders. Besides net income, other components of the Corporation’s comprehensive income include the after tax effect of changes in the net unrealized gain/loss on securities available for sale, changes in the net actuarial gain/loss on defined benefit post-retirement benefit plans and changes in the accumulated gain/loss on effective cash flow hedging instruments. Comprehensive income for the six months ended June 30, 2009 and 2008 is reported in the accompanying consolidated statements of changes in shareholders’ equity. The Corporation had comprehensive income of $6.3 million for the three months ended June 30, 2009 and comprehensive loss of $26.8 million for the three months ended June 30, 2008. Comprehensive income during the three months ended June 30, 2009 included a net after-tax loss of $5.4 million due to an decrease in the net unrealized gain on securities available for sale and $27.0 million due to a change in the accumulated gain/loss on cash flow hedging derivatives. The comprehensive loss during the three months ended June 30, 2008 included a net after-tax loss of $46.1 million due to an increase in the net unrealized loss on securities available for sale and $33.4 million due to a change in the accumulated gain/loss on cash flow hedging derivatives.

Earnings Per Share. Effective January 1, 2009, the Corporation adopted Financial Accounting Standards Board Staff Position (FSP) No. EITF 03-6-1, “Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities.” FSP EITF 03-6-1 provides that unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the

7

computation of earnings per share pursuant to the two-class method. The Corporation has determined that its outstanding non-vested stock awards and deferred stock units are participating securities. Accordingly, effective January 1, 2009, earnings per common share is computed using the two-class method prescribed by SFAS 128, “Earnings Per Share.” All previously reported earnings per common share data has been retrospectively adjusted to conform to the new computation method.

Reclassifications. Certain items in prior financial statements have been reclassified to conform to the current presentation.

Declines in the fair value of held-to-maturity and available-for-sale securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses to the extent the impairment is related to credit losses. The amount of the impairment related to other factors is recognized in other comprehensive income. In estimating other-than-temporary impairment losses, management considers, among other things, (i) the length of time and the extent to which the fair value has been less than cost, (ii) the financial condition and near-term prospects of the issuer, and (iii) the intent and ability of the Corporation to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in cost.

Management has the ability and intent to hold the securities classified as held to maturity in the table above until they mature, at which time the Corporation will receive full value for the securities. Furthermore, as of June 30, 2009, management does not have the intent to sell any of the securities classified as available for sale in the table above and believes that it is more likely than not that the Corporation will not have to sell any such securities before a recovery of cost. The unrealized losses are largely due to increases in market interest rates over the yields available at the time the underlying securities were purchased. The fair value is expected to recover as the bonds approach their maturity date or repricing date or if market yields for such investments decline. Management does not believe any of the securities are impaired due to reasons of credit quality. Accordingly, as of June 30, 2009, management believes the impairments detailed in the table above are temporary and no impairment loss has been realized in the Corporation’s consolidated income statement.

The amortized cost and estimated fair value of securities, excluding trading securities, at June 30, 2009 are presented below by contractual maturity. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations. Mortgage-backed securities and equity securities are shown separately since they are not due at a single maturity date.

Concentrations of Credit. Most of the Corporation’s lending activity occurs within the State of Texas, including the four largest metropolitan areas of Austin, Dallas/Ft. Worth, Houston and San Antonio as well as other markets. The majority of the Corporation’s loan portfolio consists of commercial and industrial and commercial real estate loans. As of June 30, 2009, other than energy, which totaled approximately 10.6%, of total loans, there were no concentrations of loans related to any single industry in excess of 10% of total loans.

Student Loans Held for Sale. Student loans are primarily originated for resale on the secondary market. These loans, which are generally sold on a non-recourse basis, are carried at the lower of cost or market on an aggregate basis. During the second quarter of 2008, the Corporation elected to discontinue the origination of student loans for resale, aside from previously outstanding commitments.

Foreign Loans. The Corporation has U.S. dollar denominated loans and commitments to borrowers in domiciled in Mexico as well as certain non-U.S. dollar denominated loans and commitments to borrowers domiciled in the United States. The outstanding balance of these loans and the unfunded amounts available under these commitments were not significant at June 30, 2009 or December 31, 2008.

Non-Performing/Past Due Loans. Loans are placed on non-accrual status when, in management’s opinion, the borrower may be unable to meet payment obligations, which typically occurs when principal or interest payments are more than 90 days past due. Non-accrual loans totaled $168.8 million at June 30, 2009 and $65.2 million at December 31, 2008. Accruing loans past due more than 90 days totaled $41.1 million at June 30, 2009 and $19.8 million at December 31, 2008.

Impaired Loans. Loans are considered impaired when, based on current information and events, it is probable the Corporation will be unable to collect all amounts due in accordance with the original contractual terms of the loan agreement, including scheduled principal and interest payments. If a loan is impaired, a specific valuation allowance is allocated, if necessary, so that the loan is reported net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Interest payments on impaired loans are typically applied to principal unless collectibility of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Impaired loans, or portions thereof, are charged off when deemed uncollectible.

10

Impaired loans were as follows:

	June 30, 2009		December 31, 2008		June 30, 2008
Balance of impaired loans with no allocated allowance	$	78,750	$	38,095	$	21,176
Balance of impaired loans with an allocated allowance		80,557		20,849		12,722
Total recorded investment in impaired loans	$	159,307	$	58,944	$	33,898
Amount of the allowance allocated to impaired loans	$	22,297	$	8,188	$	6,309

The impaired loans included in the table above were primarily comprised of collateral dependent commercial and commercial real estate loans. The average recorded investment in impaired loans was $132.7 million and $108.1 million for the three and six months ended June 30, 2009 and $28.1 million and $24.5 million for the three and six months ended June 30, 2008. No interest income was recognized on these loans subsequent to their classification as impaired.

Note 4 - Allowance for Possible Loan Losses

The allowance for possible loan losses is a reserve established through a provision for possible loan losses charged to expense, which represents management’s best estimate of probable losses that have been incurred within the existing portfolio of loans. The allowance, in the judgment of management, is necessary to reserve for estimated loan losses and risks inherent in the loan portfolio. The level of the allowance reflects management’s continuing evaluation of industry concentrations, specific credit risks, loan loss experience, current loan portfolio quality, present economic, political and regulatory conditions and unidentified losses inherent in the current loan portfolio, as well as trends in the foregoing. Portions of the allowance may be allocated for specific credits; however, the entire allowance is available for any credit that, in management’s judgment, should be charged off. While management utilizes its best judgment and information available, the ultimate adequacy of the allowance is dependent upon a variety of factors beyond the Corporation’s control, including the performance of the Corporation’s loan portfolio, the economy, changes in interest rates and the view of the regulatory authorities toward loan classifications.

Activity in the allowance for possible loan losses was as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
	2009			2008			2009			2008
Balance at the beginning of the period	$	114,168		$	92,498		$	110,244		$	92,339

Note 5 - Goodwill and Other Intangible Assets

Goodwill. Goodwill totaled $527.2 million at June 30, 2009 and $526.6 million at December 31, 2008. The increase in goodwill was related to purchase accounting adjustments related to the acquisition of a Dallas-based insurance agency on March 1, 2009.

Other Intangible Assets. Other intangible assets totaled $21.8 million at June 30, 2009 including $18.5 million related to core deposits, $2.9 million related to customer relationships and $461 thousand related to non-compete agreements. Other intangible assets totaled $24.3 million at December 31, 2008 including $21.3 million related to core deposits, $2.5 million related to customer relationships and $515 thousand related to non-compete agreements. The changes in intangibles related to customer relationships and non-compete agreements, net of amortization, were related to the aforementioned acquisition.

11

Amortization expense related to intangible assets totaled $1.7 million and $3.5 million during the three and six months ended June 30, 2009 and totaled $2.0 million and $4.0 million during the three and six months ended June 30, 2008. The estimated aggregate future amortization expense for intangible assets remaining as of June 30, 2009 is as follows:

Remainder of 2009	$	2,972

At June 30, 2009 and December 31, 2008, interest-bearing public funds deposits included $155.0 million and $215.9 million in savings and interest checking accounts, $74.5 million and $116.1 million in money market accounts, $5.1 million and $4.1 million in time accounts under $100 thousand and $130.2 million and $60.5 million in time accounts of $100 thousand or more.

Some of the Corporation’s interest-bearing deposits were obtained through brokered transactions and the Corporation’s participation in the Certificate of Deposit Account Registry Service (CDARS). Brokered money market deposits totaled $197.5 million at June 30, 2009 and $49.5 million at December 31, 2008. CDARS deposits totaled $181.3 million at June 30, 2009 and $13.3 million at December 31, 2008. Deposits from foreign sources, primarily Mexico, totaled $722.7 million at June 30, 2009 and $653.4 million at December 31, 2008.

Note 7 - Borrowed Funds

In January 2009, the Corporation borrowed an aggregate of $230 million in three separate variable-rate Federal Home Loan Bank (FHLB) advances (one $30 million advance and two $100 million advances). Each of the advances bear interest at a rate per annum equal to three-month LIBOR for the related interest period plus 0.36%, payable quarterly in January, April, July and October commencing in April 2009. Principal payments on the advances are due upon maturity in January 2019; however, the advances are redeemable at the option of the Corporation at any time. The advances are collateralized by a blanket floating lien on all first mortgage loans, certain pledged securities, the FHLB capital stock owned by the Corporation and any funds on deposit with the FHLB.

The weighted-average rate on the advances was 1.50% at June 30, 2009. Concurrent with the advances, the Corporation entered into three separate interest rate swap transactions that effectively fix the interest rates on the advances at a weighted- average rate of 2.85%. See Note 10 - Derivative Financial Instruments for additional information related to the interest rate swaps.

Note 8 - Commitments and Contingencies

Financial Instruments with Off-Balance-Sheet Risk. In the normal course of business, the Corporation enters into various transactions, which, in accordance with generally accepted accounting principles are not included in its consolidated balance sheets. The Corporation enters into these transactions to meet the financing needs of its customers. These transactions include commitments to extend credit and standby letters of credit, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The Corporation minimizes its exposure to loss under these commitments by subjecting them to credit approval and monitoring procedures.

Commitments to Extend Credit. The Corporation enters into contractual commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Substantially all of the Corporation’s commitments to extend credit are contingent upon customers maintaining specific credit standards at the time of loan funding. Commitments to extend credit totaled $4.3 billion at June 30, 2009 and $4.8 billion at December 31, 2008.

Standby Letters of Credit. Standby letters of credit are written conditional commitments issued by the Corporation to guarantee the performance of a customer to a third party. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Corporation would be required to fund the commitment. The maximum potential amount of future payments the Corporation could be required to make is represented by the contractual amount of the commitment. If the commitment were funded, the Corporation would be entitled to seek recovery from the customer. The Corporation’s policies generally require that standby letter of credit arrangements contain security and debt covenants similar to those contained in loan agreements. Standby letters of credit totaled $261.9 million at June 30, 2009 and $288.4 million at December 31, 2008.

The Corporation considers the fees collected in connection with the issuance of standby letters of credit to be representative of the fair value of its obligation undertaken in issuing the guarantee. In accordance with applicable accounting standards related to guarantees, the Corporation defers fees collected in connection with the issuance of standby letters of credit. The fees are then recognized in income proportionately over the life of the standby letter of credit agreement. The Corporation had deferred standby letter of credit fees totaling $1.4 million at both June 30, 2009 and December 31, 2008, which represents the fair value of the Corporation’s potential obligations under the standby letter of credit guarantees.

Lease Commitments. The Corporation leases certain office facilities and office equipment under operating leases. Rent expense for all operating leases totaled $5.2 million and $10.3 million for the three and six months ended June 30, 2009 and $4.7 million and $9.3 million for the three and six months ended June 30, 2008. There has been no significant change in the future minimum lease payments payable by the Corporation since December 31, 2008. See the 2008 Form 10-K for information regarding these commitments.

Litigation. The Corporation is subject to various claims and legal actions that have arisen in the normal course of conducting business. Management does not expect the ultimate disposition of these matters to have a material adverse impact on the Corporation’s financial statements.

Note 9 - Regulatory Matters

Regulatory Capital Requirements. Banks and bank holding companies are subject to various regulatory capital requirements administered by state and federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators about components, risk weighting and other factors.

Quantitative measures established by regulations to ensure capital adequacy require the maintenance of minimum amounts and ratios (set forth in the table below) of total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital to adjusted quarterly average assets (as defined).

Cullen/Frost’s and Frost Bank’s Tier 1 capital consists of shareholders’ equity excluding unrealized gains and losses on securities available for sale, the accumulated gain or loss on effective cash flow hedging derivatives, the net actuarial gain/loss on the Corporation’s defined benefit post-retirement benefit plans, goodwill and other intangible assets. Tier 1 capital for Cullen/Frost also includes $132 million of trust preferred securities issued by unconsolidated subsidiary trusts. Cullen/Frost’s and Frost Bank’s total capital is comprised of Tier 1 capital for each entity plus $60 million of the Corporation’s aggregate $150 million of 6.875% subordinated notes payable (of which the permissible portion decreases 20% per year during the final five years of the term of the notes) and a permissible portion of the allowance for possible loan losses. The Corporation’s aggregate $100 million of 5.75% fixed-to-floating rate subordinated notes are not included in Tier 1 capital but are included in total capital of Cullen/Frost.

13

The Tier 1 and total capital ratios are calculated by dividing the respective capital amounts by risk-weighted assets. Risk-weighted assets are calculated based on regulatory requirements and include total assets, excluding goodwill and other intangible assets, allocated by risk weight category, and certain off-balance-sheet items (primarily loan commitments). The leverage ratio is calculated by dividing Tier 1 capital by adjusted quarterly average total assets, which exclude goodwill and other intangible assets.

Actual and required capital ratios for Cullen/Frost and Frost Bank were as follows:

	Actual				Minimum Required for Capital Adequacy Purposes				Required to be Well Capitalized Under Prompt Corrective Action Regulations
	Capital Amount		Ratio		Capital Amount		Ratio		Capital Amount		Ratio

Cullen/Frost believes that, as of June 30, 2009, its bank subsidiary, Frost Bank, was “well capitalized” based on the ratios presented above.

Cullen/Frost is subject to the regulatory capital requirements administered by the Federal Reserve, while Frost Bank is subject to the regulatory capital requirements administered by the Office of the Comptroller of the Currency and the Federal Deposit Insurance Corporation. Regulatory authorities can initiate certain mandatory actions if Cullen/Frost or Frost Bank fail to meet the minimum capital requirements, which could have a direct material effect on the Corporation’s financial statements. Management believes, as of June 30, 2009, that Cullen/Frost and Frost Bank meet all capital adequacy requirements to which they are subject.

Dividend Restrictions. In the ordinary course of business, Cullen/Frost is dependent upon dividends from Frost Bank to provide funds for the payment of dividends to shareholders and to provide for other cash requirements. Banking regulations may limit the amount of dividends that may be paid. Approval by regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of Frost Bank to fall below specified minimum levels. Approval is also required if dividends declared exceed the net profits for that year combined with the retained net profits for the preceding two years. At June 30, 2009, Frost Bank could pay aggregate dividends of up to $255.4 million to Cullen/Frost without prior regulatory approval.

Trust Preferred Securities. In accordance with the applicable accounting standard related to variable interest entities, the accounts of the Corporation’s wholly owned subsidiary trusts, Cullen/Frost Capital Trust II and Summit Bancshares Statutory Trust I, have not been included in the Corporation’s consolidated financial statements. However, the $132.0 million in trust preferred securities issued by these subsidiary trusts have been included in the Tier 1 capital of Cullen/Frost for regulatory capital purposes pursuant to guidance from the Federal Reserve Board.

Note 10 - Derivative Financial Instruments

The fair value of derivative positions outstanding is included in accrued interest receivable and other assets and accrued interest payable and other liabilities in the accompanying consolidated balance sheets and in the net change in each of these financial statement line items in the accompanying consolidated statements of cash flows.

Interest Rate Derivatives. The Corporation utilizes interest rate swaps, caps and floors to mitigate exposure to interest rate risk and to facilitate the needs of its customers. The Corporation’s objectives for utilizing these derivative instruments is described below:

The Corporation has entered into certain interest rate swap contracts that are matched to specific fixed-rate commercial loans or leases that the Corporation has entered into with its customers. These contracts have been designated as hedging instruments to hedge the risk of changes in the fair value of the underlying commercial loan/lease due to changes in interest rates. The related contracts are structured so that the notional amounts reduce over time to generally match the expected amortization of the underlying loan/lease.

The Corporation has entered into three interest rate swap contracts on variable-rate loans with a total notional amount of $1.2 billion. The interest rate swap contracts were designated as hedging instruments in cash flow hedges with the objective of protecting the overall cash flows from the Corporation’s monthly interest receipts on a rolling portfolio of $1.2 billion of variable-rate loans outstanding throughout the 84-month period beginning in October 2007 and ending in October 2014 from the risk of variability of those cash flows such that the yield on the underlying loans would remain constant. The desired constant yield is 7.559% in the case of the first contract (underlying loan pool totaling $650.0 million carrying an interest rate equal to Prime), 8.059% in the case of the second contract (underlying loan pool totaling $230.0 million carrying an interest rate equal to Prime plus a margin of 50 basis points) and 8.559% in the case of the third contract (underlying loan pool totaling $320.0 million carrying an interest rate equal to Prime plus a margin of 100 basis points). Under the swaps, the Corporation will receive a fixed interest rate of 7.559% and pay a variable interest rate equal to the daily Federal Reserve Statistical Release H-15 Prime Rate (“Prime”), with monthly settlements.

The Corporation has entered into an interest rate swap contract on junior subordinated deferrable interest debentures with a total notional amount of $120.0 million. The interest rate swap contract was designated as a hedging instrument in a cash flow hedge with the objective of protecting the quarterly interest payments on the Corporation’s $120.0 million of junior subordinated deferrable interest debentures issued to Cullen/Frost Capital Trust II throughout the five-year period beginning in December 2008 and ending in December 2013 from the risk of variability of those payments resulting from changes in the three-month LIBOR interest rate. Under the swap, the Corporation will pay a fixed interest rate of 5.47% and receive a variable interest rate of three-month LIBOR plus a margin of 1.55% on a total notional amount of $120.0 million, with quarterly settlements.

During the first quarter of 2009, the Corporation entered into three interest rate swap contracts on FHLB advances with a total notional amount of $230.0 million. The interest rate swap contracts were designated as hedging instruments in cash flow hedges with the objective of protecting the forty quarterly interest payments on each of the Corporation’s variable-rate (three-month LIBOR plus a margin of 0.36%) FHLB advances which, in the aggregate, total $230 million throughout the forty quarterly periods beginning in January 2009 and ending in January 2019 from the risk of variability of those payments resulting from changes in the three-month LIBOR interest rate. Under the swaps, the Corporation will pay a weighted-average fixed interest rate of 2.85% and receive a variable interest rate of three-month LIBOR plus a margin of 0.36% on a total notional amount of $230.0 million, with quarterly settlements

The Corporation has entered into certain interest rate swap, cap and floor contracts that are not designated as hedging instruments. These derivative contracts relate to transactions in which the Corporation enters into an interest rate swap, cap and/or floor with a customer while at the same time entering into an offsetting interest rate swap, cap and/or floor with another financial institution. In connection with each swap transaction, the Corporation agrees to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on a similar notional amount at a fixed interest rate. At the same time, the Corporation agrees to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows the Corporation’s customer to effectively convert a variable rate loan to a fixed rate. Because the Corporation acts as an intermediary for its customer, changes in the fair value of the underlying derivative contracts for the most part offset each other and do not significantly impact the Corporation’s results of operations except in certain situations where there is a significant deterioration in the customer’s credit worthiness.

Commodity Derivatives. The Corporation enters into commodity swaps and option contracts that are not designated as hedging instruments primarily to accommodate the business needs of its customers. Upon the origination of a commodity swap or option contract with a customer, the Corporation simultaneously enters into an offsetting contract with a third party to mitigate the exposure to fluctuations in commodity prices.

The notional amounts and estimated fair values of commodity derivative positions outstanding are presented in the following table. The Corporation obtains dealer quotations to value its commodity derivative positions.

	Notional Units	June 30, 2009				December 31, 2008

Foreign Currency Derivatives. The Corporation enters into foreign currency forward contracts that are not designated as hedging instruments primarily to accommodate the business needs of its customers. Upon the origination of a foreign currency forward contract with a customer, the Corporation simultaneously enters into an offsetting contract with a third party to negate the exposure to fluctuations in foreign currency exchange rates. The Corporation also utilizes foreign currency forward contracts that are not designated as hedging instruments to mitigate the economic effect of fluctuations in foreign currency exchange rates on certain short-term, non-U.S. dollar denominated loans. The notional amounts and fair values of open foreign currency forward contracts were not significant at June 30, 2009 and December 31, 2008.

Gains, Losses and Derivative Cash Flows. For fair value hedges, the changes in the fair value of both the derivative hedging instrument and the hedged item are included in other non-interest income or other non-interest expense. The extent that such changes in fair value do not offset represents hedge ineffectiveness. Net cash flows from interest rate swaps on commercial loans/leases designated as hedging instruments in effective hedges of fair value are included in interest income on loans. For cash flow hedges, the effective portion of the gain or loss due to changes in the fair value of the derivative hedging instrument is included in other comprehensive income, while the ineffective portion (indicated by the excess of the cumulative change in the fair value of the derivative over that which is necessary to offset the cumulative change in expected future cash flows on the hedge transaction) is included in other non-interest income or other non-interest expense. Net cash flows from interest rate swaps on variable-rate loans designated as hedging instruments in effective hedges of cash flows are included in interest income on loans. Net cash flows from the interest rate swap on junior subordinated deferrable interest debentures designated as a hedging instrument in an effective hedge of cash flows are included in interest expense on junior subordinated deferrable interest debentures. Net cash flows from interest rate swaps on FHLB advances designated as hedging instruments in effective hedges of cash flows are included in interest expense on other long-term borrowings. For non-hedging derivative instruments, gains and losses due to changes in fair value and all cash flows are included in other non-interest income and other non-interest expense.

Amounts included in the consolidated statements of income related to interest rate derivatives designated as hedges of fair value were as follows:

	Three Months Ended June 30,						Six Months Ended June 30,

No ineffectiveness related to interest rate derivatives designated as hedges of cash flows was recognized in the consolidated statements of income during the reported periods. The accumulated net after-tax gain related to effective cash flow hedges included in accumulated other comprehensive income totaled $83.6 million at June 30, 2009 and $116.0 million at December 31, 2008.

As stated above, the Corporation enters into non-hedge related derivative positions primarily to accommodate the business needs of its customers. Upon the origination of a derivative contract with a customer, the Corporation simultaneously enters into an offsetting derivative contract with a third party. The Corporation recognizes immediate income based upon the difference in the bid/ask spread of the underlying transactions with its customers and the third party. Because the Corporation acts only as an intermediary for its customer, subsequent changes in the fair value of the underlying derivative contracts for the most part offset each other and do not significantly impact the Corporation’s results of operations except in certain situations where there is a significant deterioration in the customer’s credit worthiness.

Amounts included in the consolidated statements of income related to non-hedging interest rate and commodity derivative instruments were as follows:

Counterparty Credit Risk. Derivative contracts involve the risk of dealing with both bank customers and institutional derivative counterparties and their ability to meet contractual terms. Institutional counterparties must have an investment grade credit rating and be approved by the Corporation’s Asset/Liability Management Committee. The Corporation’s credit exposure on interest rate swaps is limited to the net favorable value and interest payments of all swaps by each counterparty, while the Corporation’s credit exposure on commodity swaps/options is limited to the net favorable value of all swaps/options by each counterparty. Credit exposure may be reduced by the amount of collateral pledged by the counterparty. There are no credit-risk-related contingent features associated with any of the Corporation’s derivative contracts.

18

The Corporation’s credit exposure relating to interest rate swaps and commodity swaps/options with bank customers was approximately $39.2 million at June 30, 2009. This credit exposure is partly mitigated as transactions with customers are generally secured by the collateral, if any, securing the underlying transaction being hedged. The Corporation’s credit exposure, net of collateral pledged, relating to interest rate swaps and commodity swaps/options with upstream financial institution counterparties was approximately $1.6 million at June 30, 2009. Collateral levels for upstream financial institution counterparties are monitored and adjusted as necessary.

The aggregate fair value of securities posted as collateral by the Corporation related to derivative contracts totaled $12.9 million at June 30, 2009. At such date, the Corporation also had $5.8 million in cash collateral on deposit with other financial institution counterparties.

Note 11 - Earnings Per Common Share

Earnings per common share is computed using the two-class method prescribed by SFAS 128, “Earnings Per Share.” Basic earnings per common share is computed by dividing net earnings allocated to common stock by the weighted-average number of common shares outstanding during the applicable period, excluding outstanding participating securities. Participating securities include non-vested stock awards and deferred stock units, though no actual shares of common stock related to deferred stock units have been issued. Non-vested stock awards and deferred stock units are considered participating securities because holders of these securities receive non-forfeitable dividends at the same rate as holders of the Corporation’s common stock. Diluted earnings per common share is computed using the weighted-average number of shares determined for the basic earnings per common share computation plus the dilutive effect of stock compensation using the treasury stock method.

The following table presents a reconciliation of the number of shares used in the calculation of basic and diluted earnings per common share.

	Three Months Ended June 30,				Six Months Ended June 30,
	2009		2008		2009		2008
Distributed earnings allocated to common stock	$	25,538	$	24,674	$	50,397	$	48,141
Undistributed earnings allocated to common stock		12,168		27,662		32,113		56,765
Net earnings allocated to common stock	$	37,706	$	52,336	$	82,510	$	104,906
Weighted-average shares outstanding for basic earnings per common share		59,330,716		58,732,666		59,260,030		58,635,340
Dilutive effect of stock compensation		119,114		359,526		78,055		391,485
Weighted-average shares outstanding for diluted earnings per common share		59,449,830		59,092,192		59,338,085		59,026,825

During the second quarter of 2009, the Corporation awarded non-employee directors a total of 7,238 deferred stock units. As of June 30, 2009, 12,688 deferred stock units were outstanding. Upon retirement from the Corporation’s board of directors, non-employee directors will receive one share of the Corporation’s common stock for each deferred stock unit held. The deferred stock units were fully vested upon being awarded and will receive equivalent dividend payments as such dividends are declared on the Corporation’s common stock.

19

During the six months ended June 30, 2009 and 2008, proceeds from stock option exercises totaled $7.9 million and $26.8 million. During the six months ended June 30, 2009, all of the shares issued in connection with stock option exercises were issued from available treasury stock.

Stock-based compensation expense totaled $3.4 million and $6.4 million during the three and six months ended June 30, 2009 and $2.7 million and $5.1 million during the three and six months ended June 30, 2008. Stock-based compensation expense is recognized ratably over the requisite service period for all awards. Unrecognized stock-based compensation expense related to stock options totaled $17.5 million at June 30, 2009, while unrecognized stock-based compensation expense related to non-vested stock awards totaled $5.7 million at June 30, 2009.

Note 13 - Defined Benefit Plans

The components of the combined net periodic benefit cost for the Corporation’s qualified and non-qualified defined benefit pension plans were as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
	2009			2008			2009			2008
Expected return on plan assets, net of expenses	$	(2,281	)	$	(2,310	)	$	(4,563	)	$	(4,620	)
Interest cost on projected benefit obligation		1,993			1,935			3,986			3,871
Net amortization and deferral		1,057			308			2,115			615
Net periodic benefit cost	$	769		$	(67	)	$	1,538		$	(134	)

The Corporation’s non-qualified defined benefit pension plan is not funded. No contributions to the qualified defined benefit pension plan were made during the six months ended June 30, 2009. The Corporation does not expect to make any contributions during the remainder of 2009.

Note 14 - Income Taxes

Income tax expense was as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
	2009			2008			2009			2008
Current income tax expense	$	14,742		$	22,171		$	32,337		$	45,279
Deferred income tax expense (benefit)		(3,021	)		773			(5,202	)		948
Income tax expense as reported	$	11,721		$	22,944		$	27,135		$	46,227
Effective tax rate		23.6	%		30.4	%		24.7	%		30.5	%

Net deferred tax liabilities totaled $47.8 million at June 30, 2009 and $61.3 million at December 31, 2008. No valuation allowance was recorded against deferred tax assets at June 30, 2009 as management believes that it is more likely than not that all of the deferred tax assets will be realized because they were supported by recoverable taxes paid in prior years.

The Corporation files income tax returns in the U.S. federal jurisdiction. The Company is no longer subject to U.S. federal income tax examinations by tax authorities for years before 2005. During the third quarter of 2007, the Internal Revenue Service (“IRS”) completed an examination of the Corporation’s U.S. income tax returns for 2004 and 2005. The adjustments resulting from the examination did not have a significant impact on the Corporation’s financial statements.

Note 15 - Operating Segments

The Corporation is managed under a matrix organizational structure whereby significant lines of business, including Banking and the Financial Management Group (“FMG”), overlap a regional reporting structure. The regions are primarily based upon geographic location and include Austin, Corpus Christi, Dallas, Fort Worth, Houston, Rio Grande Valley, San Antonio and Statewide. The Corporation is primarily managed based on the line of business structure. In that regard, all regions have the same lines of business, which have the same product and service offerings, have similar types and classes of customers and utilize similar service delivery methods. Pricing guidelines for products and services are the same across all regions. The regional reporting structure is primarily a means to scale the lines of business to provide a local, community focus for customer relations and business development.

20

The Corporation has two primary operating segments, Banking and FMG, that are delineated by the products and services that each segment offers. The Banking operating segment includes both commercial and consumer banking services, Frost Insurance Agency and Frost Securities, Inc. Commercial banking services are provided to corporations and other business clients and include a wide array of lending and cash management products. Consumer banking services include direct lending and depository services. Frost Insurance Agency provides insurance brokerage services to individuals and businesses covering corporate and personal property and casualty products, as well as group health and life insurance products. Frost Securities, Inc. provides advisory and private equity services to middle market companies. The FMG operating segment includes fee-based services within private trust, retirement services, and financial management services, including personal wealth management and brokerage services. The third operating segment, Non-Banks, is for the most part the parent holding company, as well as certain other insignificant non-bank subsidiaries of the parent that, for the most part, have little or no activity. The parent company’s principal activities include the direct and indirect ownership of the Corporation’s banking and non-banking subsidiaries and the issuance of debt and equity. Its principal source of revenue is dividends from its subsidiaries.

The accounting policies of each reportable segment are the same as those of the Corporation except for the following items, which impact the Banking and FMG segments: (i) expenses for consolidated back-office operations and general overhead-type expenses such as executive administration, accounting and internal audit are allocated to operating segments based on estimated uses of those services, (ii) income tax expense for the individual segments is calculated essentially at the statutory rate, and (iii) the parent company records the tax expense or benefit necessary to reconcile to the consolidated total.

The Corporation uses a match-funded transfer pricing process to assess operating segment performance. The process helps the Corporation to (i) identify the cost or opportunity value of funds within each business segment, (ii) measure the profitability of a particular business segment by relating appropriate costs to revenues, (iii) evaluate each business segment in a manner consistent with its economic impact on consolidated earnings, and (iv) enhance asset and liability pricing decisions.

Summarized operating results by segment were as follows:

	Banking		FMG		Non-Banks			Consolidated
Revenues from (expenses to) external customers:

Note 16 - Fair Value Measurements

The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Corporation utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. SFAS 157, “Fair Value Measurements,” establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

• Level 1 Inputs - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

21

• Level 2 Inputs - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

• Level 3 Inputs - Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and the Corporation’s creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. The Corporation’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Corporation’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Furthermore, the reported fair value amounts have not been comprehensively revalued since the presentation dates, and therefore, estimates of fair value after the balance sheet date may differ significantly from the amounts presented herein. A more detailed description of the valuation methodologies used for assets and liabilities measured at fair value is set forth in the 2008 Form 10-K.

Financial Assets and Financial Liabilities: The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of June 30, 2009, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value:

	Level 1 Inputs		Level 2 Inputs		Level 3 Inputs		Total Fair Value

The following table reconciles the beginning and ending balances of derivative assets measured at fair value on a recurring basis using significant unobservable (Level 3) inputs during the six months ended June 30, 2009:

Balance, beginning of period	$	—
Transfers into Level 3		333
Net realized gains (losses)		(83	)
Balance, end of period	$	250

Certain financial assets and financial liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Financial assets and liabilities measured at fair value on a non-recurring basis during the six months ended June 30, 2009 include certain impaired loans reported at the fair value of the underlying collateral if repayment is expected solely from the collateral. Collateral values are estimated using Level 2 inputs based on observable market data or Level 3 inputs based on customized discounting criteria. During the six months ended June 30, 2009, certain impaired loans were remeasured and reported at fair value through a specific valuation allowance allocation of the allowance for possible loan losses based upon the fair value of the underlying collateral. Impaired loans with a carrying value of $17.6 million were reduced by specific valuation allowance allocations during the six months ended June 30, 2009 totaling $5.2 million to a total reported fair value of $12.2 million based on collateral valuations utilizing Level 2 valuation inputs. Impaired loans with a carrying value of $26.5 million were reduced by specific valuation allowance allocations during the six months ended June 30, 2009 totaling $5.9 million to a total reported fair value of $20.6 million based on collateral valuations utilizing Level 3 valuation inputs.

22

Non-Financial Assets and Non-Financial Liabilities: Certain non-financial assets measured at fair value on a non-recurring basis include foreclosed assets (upon initial recognition or subsequent impairment), non-financial assets and non-financial liabilities measured at fair value in the second step of a goodwill impairment test, and intangible assets and other non-financial long-lived assets measured at fair value for impairment assessment.

During the six months ended June 30, 2009, certain foreclosed assets, upon initial recognition, were remeasured and reported at fair value through a charge-off to the allowance for possible loan losses based upon the fair value of the foreclosed asset. The fair value of a foreclosed asset, upon initial recognition, is estimated using Level 2 inputs based on observable market data or Level 3 inputs based on customized discounting criteria. Foreclosed assets measured at fair value upon initial recognition totaled $12.4 million (utilizing Level 2 valuation inputs) during the six months ended June 30, 2009. In connection with the measurement and initial recognition of the foregoing foreclosed assets, the Corporation recognized charge-offs of the allowance for possible loan losses totaling $3.5 million. Other than foreclosed assets measured at fair value upon initial recognition, no foreclosed assets were remeasured at fair value during the six months ended June 30, 2009.

SFAS 107, “Disclosures about Fair Value of Financial Instruments,” as amended, requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis. A detailed description of the valuation methodologies used in estimating the fair value of financial instruments is set forth in the 2008 Form 10-K.

The estimated fair values of financial instruments were as follows:

Note 17 - New Accounting Standards

Statements of Financial Accounting Standards

SFAS No. 141, “Business Combinations (Revised 2007).” SFAS 141R replaces SFAS 141, “Business Combinations,” and applies to all transactions and other events in which one entity obtains control over one or more other businesses. SFAS 141R requires an acquirer, upon initially obtaining control of another entity, to recognize the assets, liabilities and any non-controlling interest in the acquiree at fair value as of the acquisition date. Contingent consideration is required to be recognized and measured at fair value on the date of acquisition rather than at a later date when the amount of that consideration may be determinable beyond a reasonable doubt. This fair value approach replaces the cost-allocation process required under SFAS 141 whereby the cost of an acquisition was allocated to the individual assets acquired and liabilities assumed based on their estimated fair value. SFAS 141R requires acquirers to expense acquisition-related costs as incurred rather than allocating such costs to the assets acquired and liabilities assumed, as was previously the case under SFAS 141. Under SFAS 141R, the requirements of SFAS 146, “Accounting for Costs Associated with Exit or Disposal Activities,” would have to be met in order to accrue for a restructuring plan in purchase accounting. Pre-acquisition contingencies are to be recognized at fair value, unless it is a non-contractual contingency that is not likely to materialize, in which case, nothing should be recognized in purchase accounting and, instead, that contingency would be subject to the probable and estimable recognition criteria of SFAS 5, “Accounting for Contingencies.” SFAS 141R is applicable to the Corporation’s accounting for business combinations closing on or after January 1, 2009.

SFAS No. 160, “Noncontrolling Interest in Consolidated Financial Statements, an amendment of ARB Statement No. 51.” SFAS 160 amends Accounting Research Bulletin (ARB) No. 51, “Consolidated Financial Statements,” to establish accounting and reporting standards for the non-controlling interest in a subsidiary and for the deconsolidation of a subsidiary. SFAS 160 clarifies that a non-controlling interest in a subsidiary, which is sometimes referred to as minority interest, is an ownership interest in the consolidated entity that should be reported as a component of equity in the consolidated financial statements. Among other requirements, SFAS 160 requires consolidated net income to be reported at amounts that include the amounts attributable to both the parent and the non-controlling interest. It also requires disclosure, on the face of the consolidated income statement, of the amounts of consolidated net income attributable to the parent and to the non-controlling interest. SFAS 160 became effective for the Corporation on January 1, 2009 and did not have a significant impact on the Corporation’s financial statements.

SFAS No. 161, “Disclosures About Derivative Instruments and Hedging Activities, an Amendment of FASB Statement No. 133.” SFAS 161 amends SFAS 133, “Accounting for Derivative Instruments and Hedging Activities,” to amend and expand the disclosure requirements of SFAS 133 to provide greater transparency about (i) how and why an entity uses derivative instruments, (ii) how derivative instruments and related hedge items are accounted for under SFAS 133 and its related interpretations, and (iii) how derivative instruments and related hedged items affect an entity’s financial position, results of operations and cash flows. To meet those objectives, SFAS 161 requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of gains and losses on derivative instruments and disclosures about credit-risk-related contingent features in derivative agreements. SFAS 161 became effective for the Corporation on January 1, 2009 and the required disclosures are reported in Note 10 - Derivative Financial Instruments.

SFAS No. 165, “Subsequent Events.” SFAS 165 establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or available to be issued. SFAS 165 defines (i) the period after the balance sheet date during which a reporting entity’s management should evaluate events or transactions that may occur for potential recognition or disclosure in the financial statements (ii) the circumstances under which an entity should recognize events or transactions occurring after the balance sheet date in its financial statements, and (iii) the disclosures an entity should make about events or transactions that occurred after the balance sheet date. SFAS 165 became effective for the Corporation’s financial statements for periods ending after June 15, 2009. SFAS 165 did not have a significant impact on the Corporation’s financial statements.

SFAS No. 166, “Accounting for Transfers of Financial Assets, an Amendment of FASB Statement No. 140.” SFAS 166 amends SFAS 140, “Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities,” to enhance reporting about transfers of financial assets, including securitizations, and where companies have continuing exposure to the risks related to transferred financial assets. SFAS 166 eliminates the concept of a “qualifying special-purpose entity” and changes the requirements for derecognizing financial assets. SFAS 166 also requires additional disclosures about all continuing involvements with transferred financial assets including information about gains and losses resulting from transfers during the period. SFAS 166 will be effective January 1, 2010 and is not expected to have a significant impact on the Corporation’s financial statements.

24

SFAS No. 167, “Amendments to FASB Interpretation No. 46(R).” SFAS 167 amends FIN 46 (Revised December 2003), “Consolidation of Variable Interest Entities,” to change how a company determines when an entity that is insufficiently capitalized or is not controlled through voting (or similar rights) should be consolidated. The determination of whether a company is required to consolidate an entity is based on, among other things, an entity’s purpose and design and a company’s ability to direct the activities of the entity that most significantly impact the entity’s economic performance. SFAS 167 requires additional disclosures about the reporting entity’s involvement with variable-interest entities and any significant changes in risk exposure due to that involvement as well as its affect on the entity’s financial statements. SFAS 167 will be effective January 1, 2010 and is not expected to have a significant impact on the Corporation’s financial statements.

SFAS No. 168, “The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles, a Replacement of FASB Statement No. 162.” SFAS 168 replaces SFAS 162, “The Hierarchy of Generally Accepted Accounting Principles” and establishes the FASB Accounting Standards Codification (the “Codification”) as the source of authoritative accounting principles recognized by the FASB to be applied by non-governmental entities in the preparation of financial statements in conformity with generally accepted accounting principles. Rules and interpretive releases of the SEC under authority of federal securities laws are also sources of authoritative guidance for SEC registrants. All guidance contained in the Codification carries an equal level of authority. All non-grandfathered, non-SEC accounting literature not included in the Codification is superseded and deemed non-authoritative. SFAS 168 will be effective for the Corporation’s financial statements for periods ending after September 15, 2009. SFAS 168 is not expected have a significant impact on the Corporation’s financial statements.

Financial Accounting Standards Board Staff Positions and Interpretations

FSP EITF 03-6-1, “Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities.” FSP EITF 03-6-1 provides that unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of earnings per share pursuant to the two-class method. FSP EITF 03-6-1 became effective on January 1, 2009. See Note 1 - Significant Accounting Policies.

FSP SFAS. 132R-1, “Employers’ Disclosures about Postretirement Benefit Plan Assets.” FSP SFAS 132R-1 provides guidance related to an employer’s disclosures about plan assets of defined benefit pension or other post-retirement benefit plans. Under FSP SFAS 132R-1, disclosures should provide users of financial statements with an understanding of how investment allocation decisions are made, the factors that are pertinent to an understanding of investment policies and strategies, the major categories of plan assets, the inputs and valuation techniques used to measure the fair value of plan assets, the effect of fair value measurements using significant unobservable inputs on changes in plan assets for the period and significant concentrations of risk within plan assets. The disclosures required by FSP SFAS 132R-1 will be included in the Corporation’s financial statements beginning with the financial statements for the year-ended December 31, 2009.

FSP SFAS 157-4, “Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly.” FSP SFAS 157-4 affirms that the objective of fair value when the market for an asset is not active is the price that would be received to sell the asset in an orderly transaction, and clarifies and includes additional factors for determining whether there has been a significant decrease in market activity for an asset when the market for that asset is not active. FSP SFAS 157-4 requires an entity to base its conclusion about whether a transaction was not orderly on the weight of the evidence. FSP SFAS 157-4 also amended SFAS 157, “Fair Value Measurements,” to expand certain disclosure requirements. The Corporation adopted the provisions of FSP SFAS 157-4 during the first quarter of 2009. Adoption of FSP SFAS 157-4 did not significantly impact the Corporation’s financial statements.

FSP SFAS 115-2 and SFAS 124-2, “Recognition and Presentation of Other-Than-Temporary Impairments.” FSP SFAS 115-2 and SFAS 124-2 (i) changes existing guidance for determining whether an impairment is other than temporary to debt securities and (ii) replaces the existing requirement that the entity’s management assert it has both the intent and ability to hold an impaired security until recovery with a requirement that management assert: (a) it does not have the intent to sell the security; and (b) it is more likely than not it will not have to sell the security before recovery of its cost basis. Under FSP SFAS 115-2 and SFAS 124-2, declines in the fair value of held-to-maturity and available-for-sale securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses to the extent the impairment is related to credit losses. The amount of the impairment related to other factors is recognized in other comprehensive income. The Corporation adopted the provisions of FSP SFAS 115-2 and SFAS 124-2 during the first quarter of 2009. Adoption of FSP SFAS 115-2 and SFAS 124-2 did not significantly impact the Corporation’s financial statements.

FSP SFAS 107-1 and APB 28-1, “Interim Disclosures about Fair Value of Financial Instruments.” FSP SFAS 107-1 and APB 28-1 amends SFAS 107, “Disclosures about Fair Value of Financial Instruments,” to require an entity to provide disclosures about the fair value of financial instruments in interim financial information and amends Accounting Principles Board (APB) Opinion No. 28, “Interim Financial Reporting,” to require those disclosures in summarized financial information at interim reporting periods. The new interim disclosures required by FSP SFAS 107-1 and APB 28-1 are included in Note 16 - Fair Value Measurements.

25

FSP SFAS 141R-1, “Accounting for Assets Acquired and Liabilities Assumed in a Business Combination That Arise from Contingencies.” FSP SFAS 141R-1 amends the guidance in SFAS 141R to require that assets acquired and liabilities assumed in a business combination that arise from contingencies be recognized at fair value if fair value can be reasonably estimated. If fair value of such an asset or liability cannot be reasonably estimated, the asset or liability would generally be recognized in accordance with SFAS 5, “Accounting for Contingencies,” and FASB Interpretation (FIN) No. 14, “Reasonable Estimation of the Amount of a Loss.” FSP SFAS 141R-1 removes subsequent accounting guidance for assets and liabilities arising from contingencies from SFAS 141R and requires entities to develop a systematic and rational basis for subsequently measuring and accounting for assets and liabilities arising from contingencies. FSP SFAS 141R-1 eliminates the requirement to disclose an estimate of the range of outcomes of recognized contingencies at the acquisition date. For unrecognized contingencies, entities are required to include only the disclosures required by SFAS 5. FSP SFAS 141R-1 also requires that contingent consideration arrangements of an acquiree assumed by the acquirer in a business combination be treated as contingent consideration of the acquirer and should be initially and subsequently measured at fair value in accordance with SFAS 141R. FSP SFAS 141R-1 is effective for assets or liabilities arising from contingencies the Corporation acquires in business combinations occurring after January 1, 2009.

Application of Critical Accounting Policies and Accounting Estimates

The accounting and reporting policies followed by the Corporation conform, in all material respects, to accounting principles generally accepted in the United States and to general practices within the financial services industry. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. While the Corporation bases estimates on historical experience, current information and other factors deemed to be relevant, actual results could differ from those estimates.

The Corporation considers accounting estimates to be critical to reported financial results if (i) the accounting estimate requires management to make assumptions about matters that are highly uncertain and (ii) different estimates that management reasonably could have used for the accounting estimate in the current period, or changes in the accounting estimate that are reasonably likely to occur from period to period, could have a material impact on the Corporation’s financial statements. Accounting policies related to the allowance for possible loan losses are considered to be critical, as these policies involve considerable subjective judgment and estimation by management.

For additional information regarding critical accounting policies, refer to Note 1 - Summary of Significant Accounting Policies in the notes to consolidated financial statements and the sections captioned “Application of Critical Accounting Policies” and “Allowance for Possible Loan Losses” in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in the 2008 Form 10-K. There have been no significant changes in the Corporation’s application of critical accounting policies related to the allowance for possible loan losses since December 31, 2008.

Overview

A discussion of the Corporation’s results of operations is presented below. Certain reclassifications have been made to make prior periods comparable. Taxable-equivalent adjustments are the result of increasing income from tax-free loans and securities by an amount equal to the taxes that would be paid if the income were fully taxable based on a 35% federal income tax rate, thus making tax-exempt asset yields comparable to taxable asset yields. All of the Corporation’s acquisitions during the reported periods were accounted for as purchase transactions, and as such, their related results of operations are included from the date of acquisition.

28

Results of Operations

Net income totaled $37.9 million, or $0.63 diluted per share, for the three months ended June 30, 2009 compared to $52.5 million, or $0.89 diluted per share, for the three months ended June 30, 2008 and $45.0 million, or $0.76 diluted per share, for the three months ended March 31, 2009. Net income totaled $82.8 million, or $1.39 diluted per share, for the six months ended June 30, 2009 compared to $105.3 million, or $1.78 diluted per share, for the six months ended June 30, 2008.

Selected income statement data and other selected data for the comparable periods was as follows:

	Three Months Ended									Six Months Ended
	June 30, 2009			March 31, 2009			June 30, 2008			June 30, 2009			June 30, 2008

Net income decreased $14.7 million, or 28.0%, for the three months ended June 30, 2009 and decreased $22.5 million, or 21.4%, for six months ended June 30, 2009 compared to the same periods in 2008. The decrease during the three months ended June 30, 2009 was primarily the result of a $16.2 million increase in non-interest expense, a $10.3 million increase in the provision for possible loan losses and a $2.6 million decrease in non-interest income partly offset by a $3.1 million increase in net interest income and an $11.2 million decrease in income tax expense. The decrease during the six months ended June 30, 2009 was primarily the result of a $25.7 million increase in non-interest expense, a $15.9 million increase in the provision for possible loan losses and a $2.9 million decrease in non-interest income partly offset by a $2.9 million increase in net interest income and a $19.1 million decrease in income tax expense.

Net income for the second quarter of 2009 decreased $7.1 million, or 15.8%, from the first quarter of 2009. The decrease was primarily the result of a $7.0 million increase in the provision for possible loan losses, a $6.8 million increase in non-interest expense and a $1.9 million decrease in non-interest income partly offset by a $4.8 million increase in net interest income and a $3.7 million decrease in income tax expense

Details of the changes in the various components of net income are further discussed below.

Net Interest Income

Net interest income is the difference between interest income on earning assets, such as loans and securities, and interest expense on liabilities, such as deposits and borrowings, which are used to fund those assets. Net interest income is the Corporation’s largest source of revenue, representing 65.7% of total revenue during the first six months of 2009. Net interest margin is the ratio of taxable-equivalent net interest income to average earning assets for the period. The level of interest rates and the volume and mix of earning assets and interest-bearing liabilities impact net interest income and net interest margin.

The Federal Reserve Board influences the general market rates of interest, including the deposit and loan rates offered by many financial institutions. The Corporation’s loan portfolio is significantly affected by changes in the prime interest rate. The prime interest rate, which is the rate offered on loans to borrowers with strong credit, began 2008 at 7.25% and decreased 200 basis points in the first quarter, 25 basis points in the second quarter and 175 basis points in the fourth quarter to end the

29

year at 3.25%. During the first six months of 2009, the prime interest rate remained at 3.25% for the entire period. The Corporation’s loan portfolio is also impacted, to a lesser extent, by changes in the London Interbank Offered Rate (LIBOR). At June 30, 2008, the one-month and three-month U.S. dollar LIBOR rates were 2.46% and 2.78%, respectively, while at June 30, 2009, the one-month and three-month U.S. dollar LIBOR rates were 0.31% and 0.60%, repectively. The intended federal funds rate, which is the cost of immediately available overnight funds, has moved in a similar manner to the prime interest rate. It began 2008 at 4.25% and decreased 200 basis points in the first quarter, 25 basis points in the second quarter and 175 to 200 basis in the fourth quarter to end the year at zero to 0.25%. During the first six months of 2009, the intended federal funds rate remained at zero to 0.25% for the entire period.

The Corporation’s balance sheet has historically been asset sensitive, meaning that earning assets generally reprice more quickly than interest-bearing liabilities. Therefore, the Corporation’s net interest margin was likely to increase in sustained periods of rising interest rates and decrease in sustained periods of declining interest rates. In an effort to make the Corporation’s balance sheet less sensitive to changes in interest rates, the Corporation entered into various interest rate swaps which effectively convert certain floating rate loans and borrowings into fixed rate instruments for a period of time (see Note 10 - Derivative Financial Instruments). As a result, the Corporation’s balance sheet is more interest-rate neutral and changes in interest rates are expected to have a less significant impact on the Corporation’s net interest margin than would have otherwise been the case. The Corporation is primarily funded by core deposits, with non-interest-bearing demand deposits historically being a significant source of funds. This lower-cost funding base is expected to have a positive impact on the Corporation’s net interest income and net interest margin in a rising interest rate environment. The Corporation currently believes it is reasonably possible the federal funds rate and the prime interest rate will remain at the current, historically-low levels for the foreseeable future; however, there can be no assurance to that effect or as to the magnitude of any change in market interest rates should a change occur, as such changes are dependent upon a variety of factors that are beyond the Corporation’s control. Further analysis of the components of the Corporation’s net interest margin is presented below.

The following table presents the changes in taxable-equivalent net interest income and identifies the changes due to differences in the average volume of earning assets and interest-bearing liabilities and the changes due to changes in the average interest rate on those assets and liabilities. The changes in net interest income due to changes in both average volume and average interest rate have been allocated to the average volume change or average interest rate change in proportion to the absolute amounts of the change in each. The comparisons between the quarters include an additional change factor that shows the effect of the difference in the number of days in each period, as further discussed below.

	Second Quarter 2009 vs. Second Quarter 2008			Second Quarter 2009 vs. First Quarter 2009			First Six Months 2009 vs. First Six Months 2008
Due to changes in average volumes	$	20,262		$	6,696		$	21,271
Due to changes in average interest rates		(12,160	)		(1,690	)		(8,715	)
Due to difference in the number days in each of the comparable periods		—			1,586			(1,489	)
Total change	$	8,102		$	6,592		$	11,067

Taxable-equivalent net interest income for the three months ended June 30, 2009 increased $8.1 million, or 5.9%, compared to the same period in 2008. The increase primarily resulted from an increase in the average volume of interest-earning assets partly offset by a decrease in the net interest margin. The average volume of interest-earning assets for the three months ended June 30, 2009 increased $1.9 billion compared to the same period in 2008. Over the same time frame, the net interest margin decreased 40 basis points from 4.68% in 2008 to 4.28% in 2009.

Taxable-equivalent net interest income for the six months ended June 30, 2009 increased $11.1 million, or 4.1%, compared to the same period in 2008. The increase primarily resulted from an increase in the average volume of interest-earning assets partly offset by a decrease in the net interest margin and the effect of a decrease in the number of days in the first six months of 2009 due to a leap year in 2008. The average volume of interest-earning assets for the first six months of 2009 increased $1.6 billion compared to the same period in 2008. Over the same time frame, the net interest margin decreased 37 basis points from 4.67% in 2008 to 4.30% in 2009. Taxable-equivalent net interest income for the first six months of 2009 included 181 days compared to 182 days for the first six months of 2008. The additional day added approximately $1.5 million to taxable-equivalent net interest income during the first six months of 2008. Excluding the impact of the additional day during the first six months of 2008 results in an effective increase in taxable-equivalent net interest income of approximately $12.6 million during the first six months of 2009 compared to the same period in 2008. This effective increase was the result of the aforementioned increase in the average volume of interest-earning assets. The net interest margin decreased during the first six months of 2009 compared to the same period in 2008 in part due to the decrease in market interest rates discussed above. The net interest margin was also partly impacted by an increase in the proportion of average interest-earning assets

30

invested in lower yielding interest-bearing deposits during 2009 compared to 2008. The average yield on interest-earning assets decreased 103 basis points from 6.06% during the first six months of 2008 to 5.03% during the first six months of 2009, while the average cost of funds decreased 92 basis points from 1.97% during the first six months of 2008 to 1.05% during the first six months of 2009. The effect of lower average market interest rates on the average yield on average interest-earning assets was partly limited by the aforementioned interest rate swaps on variable-rate loans.

Taxable-equivalent net interest income for the second quarter of 2009 increased $6.6 million, or 4.8%, from the first quarter of 2009. The increase primarily resulted from an increase in the average volume of interest-earning assets partly offset by a decrease in the net interest margin. The average volume of interest-earning assets for the second quarter of 2009 increased $690.2 million compared to the first quarter of 2009. The net interest margin decreased 5 basis points from 4.33% in the first quarter of 2009 to 4.28% in the second quarter of 2009. The decrease in the net interest margin was partly due to an increase in the proportion of average interest-earning assets invested in lower yielding interest-bearing deposits during the second quarter. Taxable-equivalent net interest income for the second quarter of 2009 was also impacted by an increase in the number of days compared to the first quarter of 2009. Taxable-equivalent net interest income for the first quarter of 2009 included 90 days compared to 91 days for the second quarter of 2009. The additional day added approximately $1.6 million to taxable-equivalent net interest income during the second quarter of 2009. Excluding the impact of the additional day during the second quarter of 2009 results in an effective increase in taxable-equivalent net interest income of approximately $5.0 million during the second quarter of 2009 which was primarily related to the aforementioned increase in average interest-earning assets and the offsetting effect of the decrease in the net interest margin.

The average yield on interest-earning assets totaled 5.03% during the six months ended June 30, 2009 compared to 6.06% during the six months ended June 30, 2008. The average yield on interest-earning assets is primarily impacted by changes in market interest rates as well as changes in the volume and relative mix of interest-earning assets. As stated above, market interest rates decreased to historically low levels during 2008 and remained at those levels during the first six months of 2009. The average volume of loans increased $743.8 million during the six months ended June 30, 2009 compared to the same period in 2008. Loans made up approximately 66.2% of average interest-earning assets during the first six months of 2009 compared to 69.1% during the first six months of 2008. The average yield on loans was 5.05% during the six months ended June 30, 2009 compared to 6.43% during the six months ended June 30, 2008. The average volume of securities increased $599.4 million during the six months ended June 30, 2009 compared to the same period in 2008. Securities made up approximately 30.1% of average interest-earning assets during the six months ended June 30, 2009 compared to 29.1% during the six months ended June 30, 2008. The average yield on securities was 5.57% during the six months ended June 30, 2009 compared to 5.36% during the six months ended June 30, 2008. The increase in the average yield on securities during the first six months ended June 30, 2009 compared to the same period in 2008 resulted as the Corporation had a larger proportion of securities invested in higher-yielding, tax-exempt municipal securities. Average federal funds sold, resell agreements and interest-bearing deposits during the six months ended June 30, 2009 increased $284.7 million compared to the same period a year ago. Federal funds sold, resell agreements and interest-bearing deposits made up approximately 3.7% of average interest-earning assets during the six months ended June 30, 2009 compared to 1.8% during the same period in 2008. The combined average yield on federal funds sold, resell agreements and interest-bearing deposits was 0.29% during the six months ended June 30, 2009 compared to 2.91% during the same period a year ago.

Average deposits increased $1.4 billion during the first six months of 2009 compared to the same period in 2008. Average interest-bearing deposits for the first six months of 2009 increased $886.8 million compared to the same period in 2008. The ratio of average interest-bearing deposits to total average deposits was 65.7% during the first six months of 2009 compared to 66.1% during the same period in 2008. The average cost of interest-bearing deposits and total deposits was 0.81% and 0.54% during the first six months of 2009 compared to 1.76% and 1.16% during the first six months of 2008. The decrease in the average cost of interest-bearing deposits was primarily the result of decreases in interest rates offered on deposit products due to decreases in average market interest rates.

The Corporation’s net interest spread, which represents the difference between the average rate earned on earning assets and the average rate paid on interest-bearing liabilities, was 3.98% during the first six months of 2009 compared to 4.09% during the first six months of 2008. The net interest spread, as well as the net interest margin, will be impacted by future changes in short-term and long-term interest rate levels, as well as the impact from the competitive environment. A discussion of the effects of changing interest rates on net interest income is set forth in Item 3. Quantitative and Qualitative Disclosures About Market Risk included elsewhere in this report.

The Corporation’s hedging policies permit the use of various derivative financial instruments, including interest rate swaps, swaptions, caps and floors, to manage exposure to changes in interest rates. Details of the Corporation’s derivatives and hedging activities are set forth in Note 10 - Derivative Financial Instruments in the accompanying notes to consolidated financial statements included elsewhere in this report. Information regarding the impact of fluctuations in interest rates on the Corporation’s derivative financial instruments is set forth in Item 3. Quantitative and Qualitative Disclosures About Market Risk included elsewhere in this report.

Provision for Possible Loan Losses

The provision for possible loan losses is determined by management as the amount to be added to the allowance for possible loan losses after net charge-offs have been deducted to bring the allowance to a level which, in management’s best estimate, is necessary to absorb probable losses within the existing loan portfolio. The provision for possible loan losses totaled $16.6 million and $26.2 million for the three and six months ended June 30, 2009 compared to $6.3 million and $10.3 million for the three and six months ended June 30, 2008. See the section captioned “Allowance for Possible Loan Losses” elsewhere in this discussion for further analysis of the provision for possible loan losses.

Non-Interest Income

The components of non-interest income were as follows:

	Three Months Ended							Six Months Ended
	June 30, 2009		March 31, 2009		June 30, 2008			June 30, 2009		June 30, 2008
Trust fees	$	16,875	$	15,969	$	19,040		$	32,844	$	37,322
Service charges on deposit accounts		25,152		24,910		21,634			50,062		41,227
Insurance commissions and fees		7,106		10,751		7,015			17,857		18,173
Other charges, commissions and fees		6,288		6,762		9,496			13,050		16,427
Net gain (loss) on securities transactions		49		—		(56	)		49		(104	)
Other		12,536		11,472		13,452			24,008		27,764
Total	$	68,006	$	69,864	$	70,581		$	137,870	$	140,809

Total non-interest income for the three and six months ended June 30, 2009 decreased $2.6 million, or 3.6%, and $2.9 million, or 2.1%, compared to the same periods in 2008. Total non-interest income for the second quarter of 2009 decreased $1.9 million, or 2.7%, compared to the first quarter of 2009. Changes in the components of non-interest income are discussed below.

Trust Fees. Trust fee income for the three and six months ended June 30, 2009 decreased $2.2 million, or 11.4%, and $4.5 million, or 12.0%, compared to the same periods in 2008. Investment fees are the most significant component of trust fees, making up approximately 70% and 69% of total trust fees for the first six months of 2009 and 2008, respectively. Investment and other custodial account fees are generally based on the market value of assets within a trust account. Volatility in the equity and bond markets impacts the market value of trust assets and the related investment fees.

The decrease in trust fee income during the three months ended June 30, 2009 compared to the same period in 2008 was primarily the result of decreases in oil and gas trust management fees (down $969 thousand) and investment fees (down $928 thousand). The decrease in trust fee income during the six months ended June 30, 2009 compared to the same period in 2008 was primarily the result of decreases in investment fees (down $2.5 million), oil and gas trust management fees (down $1.5 million) and custody fees (down $406 thousand). The decreases in oil and gas trust management fees were primarily due to a decreases in oil and natural gas prices, which impacted the amount of royalties received. The decrease in investment and custody fees was primarily due to the general decline in the market values of assets in trust accounts on which these fees are generally based. Equity valuations during the first six months of 2009 have been significantly lower on average compared to the first six months of 2008. Nonetheless, the Corporation has been successful with business development activities and customer retention, which has helped dampen the effect of the recent market correction in equity valuations.

Trust fee income for the second quarter of 2009 increased $906 thousand, or 5.7%, compared to the first quarter of 2009. The increase was primarily the result of increases in investment fees (up $797 thousand) and tax fees (up $595 thousand). These increases were partially offset by decreases in oil and gas fees (down $233 thousand) and securities lending income (down $205 thousand).

At June 30, 2009, trust assets, including both managed assets and custody assets, were primarily composed of fixed income securities (44.5% of trust assets), equity securities (35.5% of trust assets) and cash equivalents (13.1% of trust assets). The estimated fair value of trust assets was $21.7 billion (including managed assets of $9.5 billion and custody assets of $12.2 billion) at June 30, 2009, compared to $21.7 billion (including managed assets of $9.9 billion and custody assets of $11.8 billion) at December 31, 2008 and $23.9 billion (including managed assets of $10.4 billion and custody assets of $13.5 billion) at June 30, 2008.

Service Charges on Deposit Accounts. Service charges on deposit accounts for the three and six months ended June 30, 2009 increased $3.5 million, or 16.3%, and $8.8 million, or 21.4%, compared to the same periods in 2008. The increases

32

were primarily related to service charges on commercial accounts, which increased $3.0 million and $8.2 million during the three and six months ended June 30, 2009, respectively, compared to the same periods in 2008. The increase in service charges on commercial accounts was primarily related to increased treasury management fees. The increased treasury management fees resulted primarily from a lower earnings credit rate. The earnings credit rate is the value given to deposits maintained by treasury management customers. Because average market interest rates were lower during the first six months of 2009 compared to the first six months of 2008, deposit balances have become less valuable and are yielding a lower earnings credit rate. As a result, customers are paying for more of their services through fees rather than with earning credits applied to their deposit balances.

Service charges on deposit accounts for the second quarter of 2009 increased $242 thousand, or 1.0%, compared to the first quarter of 2009. The increase was primarily due to an increase in overdraft/insufficient funds charges on consumer accounts (up $903 thousand) partly offset by a decrease in service charges on commercial accounts (down $789 thousand).

Insurance Commissions and Fees. Insurance commissions and fees for the three months ended June 30, 2009 did not significantly fluctuate compared to the same period in 2008. Insurance commissions and fees for the six months ended June 30, 2009 decreased $316 thousand, or 1.7%, compared to the same period in 2008. The decrease for the six month period is related to a decrease in commission income (down $349 thousand). This decrease was limited in part by the impact of new commission revenues from agency acquisitions in the second and third quarters of 2008 and the first quarter of 2009.

Insurance commissions and fees include contingent commissions totaling $220 thousand and $3.5 million during the three and six months ended June 30, 2009 and $206 thousand and $3.5 million during the three and six months ended June 30, 2008. Contingent commissions primarily consist of amounts received from various property and casualty insurance carriers related to the loss performance of insurance policies previously placed. Such commissions are seasonal in nature and are generally received during the first quarter of each year. These commissions totaled $2.8 million and $3.0 million during the six months ended June 30, 2009 and 2008. Contingent commissions also include amounts received from various benefit plan insurance companies related to the volume of business generated and/or the subsequent retention of such business. These commissions totaled $209 thousand and $740 thousand during the three and six months ended June 30, 2009 and $206 thousand and $491 thousand during the three and six months ended June 30, 2008.

Insurance commissions and fees for the second quarter of 2009 decreased $3.6 million, or 33.9%, compared to the first quarter of 2009. The decrease was primarily due to the seasonal decrease in contingent commissions (down $3.1 million) received from various insurance carriers related to the performance of insurance policies previously placed. Commission income for the second quarter of 2009 decreased $536 thousand compared to the first quarter of 2009 primarily due to normal variation in the timing of renewals and in the market demand for insurance products.

Other Charges, Commissions and Fees. Other charges, commissions and fees for the three and six months ended June 30, 2009 decreased $3.2 million, or 33.8%, and $3.4 million, or 20.6%, compared to the same periods in 2008. The decrease during the three months ended June 30, 2009 was primarily due to a decrease in investment banking fees related to corporate advisory services (down $1.4 million) and decreases in commission income related to the sale of money market accounts (down $698 thousand), annuities (down $437 thousand) and mutual funds (down $351 thousand), as well as decreases in various other categories of service charges. Investment banking fees related to corporate advisory services are transaction based and can vary significantly from quarter to quarter. The decrease in other charges, commissions and fees during the six months ended June 30, 2009 was primarily due to a decrease in investment banking fees related to corporate advisory services (down $1.6 million) and decreases in commission income related to the sale of money market accounts (down $1.0 million), mutual funds (down $760 thousand) and annuities (down $566 thousand), as well as decreases in various other categories of service charges. These decreases were partly offset by an increase in mutual fund management fees related to Frost Investment Advisors, LLC, a newly formed registered investment advisor subsidiary of the Corporation (up $602 thousand), loan processing fees (up $411 thousand) and letter of credit fees (up $259 thousand).

Other charges, commissions and fees for the second quarter of 2009 decreased $474 thousand, or 7.0%, compared to the first quarter of 2009. The decrease was primarily due to decreases in commission income related to the sale of money market accounts (down $344 thousand) and annuities (down $254 thousand).

Net Gain/Loss on Securities Transactions. The Corporation sold available-for-sale securities with an amortized cost totaling $9.9 million during the six months ended June 30, 2009. The Corporation realized a net gain of $49 thousand on those sales. The Corporation sold available-for-sale securities with an amortized cost totaling $856.3 million during the six months ended June 30, 2008. The Corporation realized a net loss of $104 thousand on those sales. A large part of the securities sales during 2008 were related to a restructuring of the Corporation’s securities portfolio to help improve net interest income in light of actions taken by the Federal Reserve that resulted in 200 basis point declines in both the federal funds rate and the prime rate. The proceeds from the sales were reinvested in longer-term securities with higher yields. Other securities sales in 2008 were primarily related to liquidity management purposes in support of loan growth.

33

Other Non-Interest Income. Other non-interest income decreased $916 thousand, or 6.8%, for the three months ended June 30, 2009 compared to the same period in 2008. Contributing to the decrease were decreases in gains on the sale of student loans (down $971 thousand), earnings on cashier check balances (down $538 thousand) and mineral interest income (down $219 thousand). These decreases were partly offset by an increase in income from check card usage (up $326 thousand) and sundry income from various miscellaneous items (up $285 thousand). During the second quarter of 2008, the Corporation elected to discontinue the origination of student loans for resale, aside from previously outstanding commitments. Sales of student loans during 2009 have been limited as the Corporation’s student loan servicer has not been able to obtain the necessary funding required to purchase the loans. Earnings on cashier check balances decreased as the Corporation began maintaining cashiers check balances in-house during the second quarter of 2008. While the Corporation no longer receives third-party fees on cashier check balances, maintaining such balances in-house provides investable funds from which the Corporation derives interest income. Mineral interest income is related to bonus, rental and shut-in payments and oil and gas royalties received from severed mineral interests on property owned by Main Plaza Corporation, a wholly owned non-banking subsidiary of the Corporation.

Other non-interest income decreased $3.8 million, or 13.5%, for the six months ended June 30, 2009 compared to the same period in 2008. Contributing to the decrease were decreases in gains on the sale of student loans (down $1.7 million), earnings on cashier check balances (down $1.3 million), sundry income from various miscellaneous items (down $804 thousand) and income from securities trading and customer derivative activities (down $427 thousand). These decreases were partly offset by an increase in income from check card usage (up $726 thousand). During the first quarter of 2008, sundry income from various miscellaneous items included $1.9 million related to the partial redemption of shares received from the VISA, Inc. initial public offering resulting from the Corporation’s membership interest in VISA USA. A portion of the shares allocated to the Corporation in the initial public offering were withheld to cover the costs and liabilities associated with certain litigation for which the Corporation, based on its prior proportionate membership interest in VISA USA, was obligated to indemnify VISA under its indemnification agreement with VISA USA. Since a portion of the shares allocated to the Corporation in the initial public offering were withheld, the Corporation was not required to make any cash payments related to the indemnification agreement. As such, the indemnification accrual related to certain pending litigation was reversed during the first quarter of 2008 and included in the aforementioned $1.9 million of income.

Other non-interest income for the second quarter of 2009 increased $1.1 million or 9.3%, compared to the first quarter of 2009. Contributing to the increase were increases in income from securities trading and customer derivative activities (up $536 thousand), income from check card usage (up $242 thousand) and mineral interest income (up $234 thousand). The increase in securities trading and customer derivative activities was primarily related to customer interest-rate swap transaction fees.

Non-Interest Expense

The components of non-interest expense were as follows:

	Three Months Ended						Six Months Ended
	June 30, 2009		March 31, 2009		June 30, 2008		June 30, 2009		June 30, 2008

Total	$	136,289	$	129,499	$	120,090	$	265,788	$	240,130

Total non-interest expense for the three and six months ended June 30, 2009 increased $16.2 million, or 13.5%, and $25.7 million, or 10.7%, compared to the same periods in 2008. Total non-interest expense for the second quarter of 2009 increased $6.8 million, or 5.2%, compared to the first quarter of 2009. Changes in the components of non-interest expense are discussed below.

Salaries and Wages. Salaries and wages for the three and six months ended June 30, 2009 increased $2.0 million, or 3.7%, and $3.6 million, or 3.3%, compared to the same periods in 2008. The increases were primarily related to normal annual merit increases, increases in headcount, decreases in cost deferrals related to lending activity and an increase in stock-based compensation expense. The increases in these items were partly offset by a decrease in incentive compensation expense (down $2.2 million and $4.3 million for the three and six months ended June 30, 2009, respectively). Salaries and wages expense for the second quarter of 2009 did not significantly fluctuate compared to the first quarter of 2009.

34

Employee Benefits. Employee benefits expense for the three and six months ended June 30, 2009 increased $1.9 million, or 15.7%, and $3.0 million, or 11.5%, compared to the same periods in 2008. The increase during the three months ended June 30, 2009 was primarily related to increases in expenses related to the Corporation’s defined benefit retirement and restoration plans (up $837 thousand), expenses related to the Corporation’s 401(k) and profit sharing plans (up $536 thousand), payroll taxes (up $211 thousand) and an increase in medical insurance expense (up $172 thousand). The increase during the six months ended June 30, 2009 was primarily related to increases in expenses related to the Corporation’s defined benefit retirement and restoration plans (up $1.7 million), expenses related to the Corporation’s 401(k) and profit sharing plans (up $650 thousand), medical insurance expense (up $365 thousand) and payroll taxes (up $187 thousand).

Employee benefits expense for the second quarter of 2009 decreased $1.5 million, or 9.6%, compared to the first quarter of 2009 primarily due to decreases in payroll taxes (down $1.2 million) and expenses related to the Corporation’s 401(k) and profit sharing plan expenses (down $164 thousand). The Corporation generally experiences higher payroll taxes and 401(k) plan contribution matching expense during the first quarter of each year due to the increased payroll related to annual incentive compensation payments.

The Corporation’s defined benefit retirement and restoration plans were frozen effective as of December 31, 2001 and were replaced by a profit sharing plan. Management believes these actions reduce the volatility in retirement plan expense. However, the Corporation still has funding obligations related to the defined benefit and restoration plans and could recognize retirement expense related to these plans in future years, which would be dependent on the return earned on plan assets, the level of interest rates and employee turnover. The aforementioned increases in expenses related to the Corporation’s defined benefit retirement plan during the three and six months ended June 30, 2009 were partly the result of a weaker return on plan assets during 2008.

Net Occupancy. Net occupancy expense for the three and six months ended June 30, 2009 increased $773 thousand, or 7.7%, and $1.8 million, or 9.2%, compared to the same periods in 2008. The increase during the three months ended June 30, 2009 was primarily related to an increase in lease expense (up $452 thousand), repairs (up $129 thousand) and depreciation on leasehold improvements (up $113 thousand) offset by a decrease in building maintenance (down $111 thousand). The increase during the six months ended June 30, 2009 was primarily due to an increase in lease expense (up $920 thousand) and depreciation on leasehold improvements (up $224 thousand) as well as increases in various other categories of net occupancy expense. The increases in these items were partly related to the additional costs associated with new branch locations. Net occupancy expense for the second quarter of 2009 did not significantly fluctuate compared to the first quarter of 2009.

Furniture and Equipment. Furniture and equipment expense for the three and six months ended June 30, 2009 increased $1.5 million, or 16.1%, and $2.9 million, or 16.0%, compared to the same periods in 2008. The increase during the three months ended June 30, 2009 was primarily related to increases in software amortization expense (up $636 thousand), software maintenance expense (up $432 thousand) and depreciation expense related to furniture and fixtures (up $344 thousand). The increase during the six months ended June 30, 2009 was primarily related to increases in software amortization expense (up $1.2 million), software maintenance expense (up $960 thousand) and depreciation expense related to furniture and fixtures (up $620 thousand). The increases in software amortization and software maintenance expense were primarily related to certain applications related to data management, internet banking, treasury management and teller/retail delivery systems. The increases in depreciation expense related to furniture and fixtures were partly related to new branch locations. Furniture and equipment expense for the second quarter of 2009 increased $299 thousand, or 2.9%, compared to the first quarter of 2009 primarily due to increases in software amortization expense (up $168 thousand) and depreciation expense related to furniture and fixtures (up $116 thousand).

Deposit Insurance. Deposit insurance expense for the three and six months ended June 30, 2009 increased $11.0 million and $15.1 million compared to the same periods in 2008. Deposit insurance expense during the second quarter of 2009 increased $7.3 million compared to the first quarter of 2009. The increases in deposit insurance expense were due to increases in the fee assessment rates during 2009 and a special assessment applied to all insured institutions as of June 30, 2009. With regard to the increase in fee assessment rates, the FDIC finalized a rule in December 2008 that raised the then current assessment rates uniformly by 7 basis points for the first quarter of 2009 assessment. The new rule resulted in annualized assessment rates for Risk Category 1 institutions ranging from 12 to 14 basis points. In February 2009, the FDIC issued final rules to amend the deposit insurance fund restoration plan, change the risk-based assessment system and set assessment rates for Risk Category 1 institutions beginning in the second quarter of 2009. The new initial base assessment rates for Risk Category 1 institutions range from 12 to 16 basis points, on an annualized basis, and from 7 to 24 basis points after the effect of potential base-rate adjustments, in each case depending upon various factors. The increase in deposit insurance expense during the six months ended June 30, 2009 compared to the same period a year ago was also partly related to the Corporation’s utilization of available credits to offset assessments during the first six months of 2008. The increases were also partly related to the additional 10 basis point assessment paid on covered transaction accounts exceeding $250 thousand under the Temporary Liquidity Guaranty Program.

35

In May 2009, the FDIC issued a final rule which levied a special assessment applicable to all insured depository institutions totaling 5 basis points of each institution’s total assets less Tier 1 capital as of June 30, 2009, not to exceed 10 basis points of domestic deposits. The special assessment is part of the FDIC’s efforts to rebuild the Deposit Insurance Fund (“DIF”). Deposit insurance expense during the three and six months ended June 30, 2009 included a $7.3 million accrual related to the special assessment. The final rule also allows the FDIC to impose additional special assessments of 5 basis points for the third and fourth quarters of 2009, if the FDIC estimates that the DIF reserve ratio will fall to a level that would adversely affect public confidence in federal deposit insurance or to a level that would be close to or below zero. Any additional special assessment would also be capped at 10 basis points of domestic deposits. The Corporation cannot provide any assurance as to the ultimate amount or timing of any such special assessments, should such special assessments occur, as such special assessments depend upon a variety of factors which are beyond the Corporation’s control.

Intangible Amortization. Intangible amortization is primarily related to core deposit intangibles and, to a lesser extent, intangibles related to customer relationships and non-compete agreements. Intangible amortization for the three and six months ended June 30, 2009 decreased $236 thousand, or 12.1% and $501 thousand, or 12.5% compared to the same periods in 2008. The decreases in amortization expense are primarily the result of the completion of amortization of certain intangible assets, as well as a reduction in the annual amortization rate of certain intangible assets as the Corporation uses an accelerated amortization approach which results in higher amortization rates during the earlier years of the useful lives of intangible assets.

Other Non-Interest Expense. Other non-interest expense for the three and six months ended June 30, 2009 decreased $703 thousand, or 2.2%, and $282 thousand, or 0.5%, compared to the same periods in 2008. Significant components of the decrease during the three months ended June 30, 2009 included sundry expense from various miscellaneous items (down $1.5 million), travel expense (down $375 thousand) and meals and entertainment expense (down $371 thousand). Sundry expense from various miscellaneous items during the second quarter of 2008 included $1.1 million related to a settlement, release and license agreement associated with certain patent infringement claims. The decreases in the aforementioned items were partly offset by increases in advertising/promotions expenses (up $683 thousand) and property tax expense on foreclosed assets (up $573 thousand).

Significant components of the decrease during the six months ended June 30, 2009 included decreases in sundry expense from various miscellaneous items (down $1.7 million), correspondent bank service charge expense (down $513 thousand), travel expense (down $409 thousand) and meals and entertainment expense (down $396 thousand). As mentioned above, sundry expense from various miscellaneous items for 2008 included $1.1 million related to a settlement of certain patent infringement claims. The decreases in the aforementioned items were partially offset by increases in property tax expense on foreclosed assets (up $1.1 million), and increases in advertising/promotions expenses (up $627 thousand) and sub-advisor investment management fees related to Frost Investment Advisors, LLC, which began operations during the second quarter of 2008 (up $518 thousand) and decreases in cost deferrals related to lending activity (down $600 thousand).

Total other non-interest expense for the second quarter of 2009 increased $781 thousand, or 2.6%, compared to the first quarter of 2009. Significant components of the increase included increases in advertising/promotions expense (up $957 thousand) and outside director stock compensation expense (up $330 thousand) partly offset by a decreases in outside computer services expense (down $305 thousand) and losses on sale of foreclosed assets (down $249 thousand). The increase in advertising/promotions expense was primarily related to a concentrated advertising campaign that began in the second quarter. The increase in outside director compensation expense was related to a regular, annual director award of deferred stock units.

Results of Segment Operations

The Corporation’s operations are managed along two operating segments: Banking and the Financial Management Group (FMG). A description of each business and the methodologies used to measure financial performance is described in Note 15 - Operating Segments in the accompanying notes to consolidated financial statements included elsewhere in this report. Net income (loss) by operating segment is presented below:

	Three Months Ended									Six Months Ended

Banking

Net income for the three and six months ended June 30, 2009 decreased $9.6 million, or 20.2%, and $14.1 million, or 14.5%, compared to the same periods in 2008. The decrease during the three months ended June 30, 2009 was primarily the result of a $15.5 million increase in non-interest expense and a $10.3 million increase in the provision for possible loan losses partly offset by an $8.7 million decrease in income tax expense, a $6.1 million increase in net interest income and a $1.4 million increase in non-interest income. The decrease during the six months ended June 30, 2009 was primarily the result of a $24.3 million increase in non-interest expense and a $15.9 million increase in the provision for possible loan losses partly offset by a $14.6 million decrease in income tax expense, a $7.7 million increase in net interest income and a $3.8 million increase in non-interest income.

Net interest income for the three and six months ended June 30, 2009 increased $6.1 million, or 4.7%, and $7.7 million, or 3.0%, compared to the same periods in 2008. The increases were for the most part the result of increases in the average volume of earning assets partly offset by decreases the net interest margin. The increase for the six months ended June 30, 2009 was partly impacted by a decrease in the number of days during the period in 2009 due to leap year in 2008. See the analysis of net interest income included in the section captioned “Net Interest Income” included elsewhere in this discussion.

The provision for possible loan losses for the three and six months ended June 30, 2009 totaled $16.6 million and $26.2 million compared to $6.3 million and $10.3 million for the same periods in 2008. See the analysis of the provision for possible loan losses included in the section captioned “Allowance for Possible Loan Losses” included elsewhere in this discussion.

Non-interest income for the three and six months ended June 30, 2009 increased $1.4 million, or 3.1%, and $3.8 million, or 4.1%, compared to the same periods in 2008. The increases were primarily due to increases in service charges on deposits partly offset by decreases in other charges, commissions and fees and other non-interest income. The increases in service charges on deposit accounts were primarily related to increased treasury management fees on commercial accounts. The decreases in other charges, commissions and fees were primarily related to decreases in investment banking fees related to corporate advisory services and commission income related to the sale of money market accounts, annuities and mutual funds. See further analysis of these categories of non-interest income included in the section captioned “Non-Interest Income” included elsewhere in this discussion.

Non-interest expense for the three months and six ended June 30, 2009 increased $15.5 million, or 15.7%, and $24.3 million, or 12.3%, compared to the same periods in 2008. The increases were primarily due to increases in deposit insurance expense due to increases in the fee assessment rates during 2009 and a special assessment applied to all insured depository institutions as of June 30, 2009. The increases in non-interest expense during the three and six months ended June 30, 2009 compared to the same periods in 2008 were also partly due to increases in salaries and wages, employee benefits, furniture and equipment expense and net occupancy partly offset by decreases in other non-interest expense and intangible amortization. See the analysis of these items included in the section captioned “Non-Interest Expense” included elsewhere in this discussion.

Frost Insurance Agency, which is included in the Banking operating segment, had gross commission revenues of $7.1 million and $18.0 million during the three and six months ended June 30, 2009 and $7.0 million and $18.3 million during the three and six months ended June 30, 2008. Insurance commission revenues increased $92 thousand, or 1.4%, and decreased $316 thousand, or 1.7%, during the three months and six months ended June 30, 2009, respectively, compared to the same periods in 2008. See the analysis of insurance commissions and fees included in the section captioned “Non-Interest Income” included elsewhere in this discussion.

Financial Management Group (FMG)

Net income for the three and six months ended June 30, 2009 decreased $4.7 million, or 66.2%, and $8.7 million, or 65.4%, compared to the same periods in 2008. The decrease during the three months ended June 30, 2009 was primarily due to a $3.8 million decrease in non-interest income, a $2.7 million decrease in net interest income and a $657 thousand increase in non-interest expense partly offset by a $2.5 million decrease in income tax expense. The decrease during the six months ended June 30, 2009 was primarily due to a $6.9 million decrease in non-interest income, a $4.9 million decrease in net interest income and a $1.6 million increase in non-interest expense partly offset by a $4.7 million decrease in income tax expense.

Net interest income for the three and six months ended June 30, 2009 decreased $2.7 million, or 50.7%, and $4.9 million, or 44.8%, compared to the same periods in 2008. The decrease in net interest income during the six months ended June 30, 2008 was due to a decrease in the average volume of funds provided due to a decrease in the average volume of FMGs repurchase agreements combined with a decrease in the funds transfer price received for providing those funds.

Non-interest income for the three and six months ended June 30, 2009 decreased $3.8 million, or 15.5%, and $6.9 million, or 14.3%, compared to the same periods in 2008. The decreases during the three and six months ended June 30, 2009 were primarily due to decreases in trust fees (down $2.3 million and $4.7 million, respectively) and other charges, commissions and fees (down $1.6 million and $2.0 million, respectively).

Trust fee income is the most significant income component for FMG. Investment fees are the most significant component of trust fees, making up approximately 70% and 69% of total trust fees for the first six months of 2009 and 2008, respectively. Investment and other custodial account fees are generally based on the market value of assets within a trust account. Volatility in the equity and bond markets impacts the market value of trust assets and the related investment fees. The decreases in trust fee income during the three and six months ended June 30, 2009 compared to the same periods in 2008 were primarily the result of decreases in investment fees, oil and gas trust management fees and custody fees. See the analysis of trust fees included in the section captioned “Non-Interest Income” included elsewhere in this discussion.

The decreases in other charges, commissions and fees during the three and six months ended June 30, 2009 compared to the same periods in 2008 were primarily due to decreases in commission income related to the sale of money market accounts, annuities and mutual funds and decreases in brokerage commissions partly offset by increases in mutual fund management fees related to Frost Investment Advisors, LLC, a newly formed registered investment advisor subsidiary of the Corporation.

Non-interest expense for the three and six months ended June 30, 2009 increased $657 thousand, or 3.4%, and $1.6 million, or 4.2%, compared to the same periods in 2008. The increase during the three months ended June 30, 2009 was primarily due to increases in salaries and wages and employee benefits (up $692 thousand on a combined basis). The increase during the six months ended June 30, 2009 was primarily due to an increase in salaries and wages and employee benefits (up $1.0 million on a combined basis) and other non-interest expense (up $386 thousand). The increase in salaries and wages and employee benefits was primarily the result of normal, annual merit increases, increases in incentive and stock-based compensation expense and expenses related to employee benefit plans. The increase in other non-interest expense was primarily due to sub-advisor costs for Frost Investment Advisors, LLC.

Non-Banks

The net loss for the Non-Banks operating segment increased $335 thousand and decreased $261 thousand for the three and six months ended June 30, 2009, respectively, compared to the same periods in 2008. Fluctuations in various categories of income and expense were not significant.

Income Taxes

The Corporation recognized income tax expense of $11.7 million and $27.1 million, for an effective tax rate of 23.6% and 24.7% for the three and six months ended June 30, 2009 compared to $22.9 million and $46.2 million, for an effective tax rate of 30.4% and 30.5% for the three and six months ended June 30, 2008. The effective income tax rates differed from the U.S. statutory rate of 35% during the comparable periods primarily due to the effect of tax-exempt income from loans, securities and life insurance policies. The decrease in the effective tax rate during 2009 was primarily the result of an increase in holdings of tax-exempt municipal securities.

38

Average Balance Sheet

Average assets totaled $15.2 billion for the six months ended June 30, 2009 representing an increase of $1.7 billion, or 13.0%, compared to average assets for the same period in 2008. The increase was primarily reflected in interest-earning assets, which increased $1.6 billion, or 14.0%, during the first six months of 2009 compared to the same period in 2008. The increase was primarily due to a $743.8 million, or 9.2%, increase in average loans, a $599.4 million increase in average securities and a $281.7 million increase in average interest-bearing deposits and federal funds sold and resale agreements. The growth in average interest-earning assets was primarily funded by an increase in deposits. Total deposits averaged $11.8 billion for the first six months of 2009, increasing $1.4 billion, or 13.6%, compared to the same period in 2008. Average interest-bearing accounts decreased from 66.1% of average total deposits in 2008 to 65.7% of average total deposits in 2009.

Loans

Loans were as follows as of the dates indicated:

	June 30, 2009			Percent of Total		March 31, 2009			December 31, 2008			June 30, 2008

Total loans	$	8,643,693		100.0	%	$	8,778,662		$	8,844,082		$	8,353,501

Loans decreased $200.4 million, or 2.3%, compared to December 31, 2008. The majority of the Corporation’s loan portfolio is comprised of commercial and industrial loans and real estate loans. Commercial and industrial loans made up 47.5% and 48.0% of total loans at June 30, 2009 and December 31, 2008, respectively while real estate loans made up 47.8% and 47.5% of total loans, respectively, at those dates. Real estate loans include both commercial and consumer balances.

Commercial and industrial loans decreased $136.1 million, or 3.2%, from December 31, 2008 to June 30, 2009. The Corporation’s commercial and industrial loans are a diverse group of loans to small, medium and large businesses. The purpose of these loans varies from supporting seasonal working capital needs to term financing of equipment. While some short-term loans may be made on an unsecured basis, most are secured by the assets being financed with collateral margins that are consistent with the Corporation’s loan policy guidelines. The commercial and industrial loan portfolio also includes the commercial lease and asset-based lending portfolios as well as purchased shared national credits (“SNC”s), which are discussed in more detail below.

Purchased shared national credits are participations purchased from upstream financial organizations and tend to be larger in size than the Corporation’s originated portfolio. The Corporation’s purchased SNC portfolio totaled $518.6 million at June 30, 2009, decreasing $15.5 million, or 2.9%, from $534.1 million at December 31, 2008. At June 30, 2009, 63.8% of

39

outstanding purchased SNCs was related to the energy industry. The remaining purchased SNCs were diversified throughout various other industries, with no other single industry exceeding 10% of the total purchased SNC portfolio. Additionally, almost all of the outstanding balance of purchased SNCs was included in the commercial and industrial portfolio, with the remainder included in the real estate categories. SNC participations are originated in the normal course of business to meet the needs of the Corporation’s customers. As a matter of policy, the Corporation generally only participates in SNCs for companies headquartered in or which have significant operations within the Corporation’s market areas. In addition, the Corporation must have direct access to the company’s management, and either an existing banking relationship or the expectation of broadening the relationship with other banking products and services within the following 12 to 24 months. SNCs are reviewed at least quarterly for credit quality and business development successes.

Real estate loans decreased $67.4 million, or 1.6%, during the first six months of 2009. Real estate loans include both commercial and consumer balances. Commercial real estate loans totaled $3.3 billion at June 30, 2009 and represented 79.3% of total real estate loans. The majority of this portfolio consists of commercial real estate mortgages, which includes both permanent and intermediate term loans. The Corporation’s primary focus for its commercial real estate portfolio has been growth in loans secured by owner-occupied properties. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Consequently, these loans must undergo the analysis and underwriting process of a commercial and industrial loan, as well as that of a real estate loan. At June 30, 2009, approximately 59% of the outstanding principal balance of the Corporation’s commercial real estate loans were secured by owner-occupied properties.

The consumer loan portfolio, including all consumer real estate, increased $6.7 million, or 0.5%, from December 31, 2008. As the following table illustrates as of the dates indicated, the consumer loan portfolio has five distinct segments, including consumer real estate, consumer non-real estate, student loans held for sale, indirect consumer loans and 1-4 family residential mortgages.

	June 30, 2009		March 31, 2009		December 31, 2008		June 30, 2008
Consumer real estate:
Construction	$	47,523	$	53,472	$	55,947	$	67,059
Land		1,605		1,664		1,716		1,978
Home equity loans		303,465		312,959		320,220		303,507
Home equity lines of credit		154,776		141,151		122,608		101,174
Other consumer real estate		274,812		266,469		265,146		243,109
Total consumer real estate		782,181		775,715		765,637		716,827
Consumer non-real estate		349,216		343,164		348,455		326,431
Student loans held for sale		27,086		28,979		28,889		32,125
Indirect		951		1,065		1,186		1,550
1-4 family residential mortgages		70,838		80,374		79,446		87,862
Total consumer loans	$	1,230,272	$	1,229,297	$	1,223,613	$	1,164,795

The consumer non-real estate loan portfolio primarily consists of automobile loans, unsecured revolving credit products, personal loans secured by cash and cash equivalents and other similar types of credit facilities. The Corporation no longer originates 1-4 family mortgage loans and indirect consumer loans. Additionally, during the second quarter of 2008, the Corporation elected to discontinue the origination of student loans for resale, aside from previously outstanding commitments. Student loans were primarily originated for resale on the secondary market and classified as held for sale.

Non-Performing Assets

Non-performing assets include non-accrual loans and foreclosed assets. Non-performing assets at June 30, 2009 increased $112.2 million from December 31, 2008. In general, the increasing trend in non-performing assets is reflective of the current weak economic conditions. The increase in non-accrual commercial loans was partly related to the addition of six credit relationships with an aggregate total of $66.6 million. The increase in non-accrual real estate loans was primarily related to land development and 1-4 family residential construction credit relationships. Generally, loans are placed on non-accrual status if principal or interest payments become 90 days past due and/or management deems the collectibility of the principal and/or interest to be in question, as well as when required by regulatory requirements. Once interest accruals are discontinued, accrued but uncollected interest is charged to current year operations. Subsequent receipts on non-accrual loans are recorded as a reduction of principal, and interest income is recorded only after principal recovery is reasonably assured.

Foreclosed assets represent property acquired as the result of borrower defaults on loans. Foreclosed assets are recorded at estimated fair value, less estimated selling costs, at the time of foreclosure. Write-downs occurring at foreclosure are charged against the allowance for possible loan losses. On an ongoing basis, properties are appraised as required by market indications and applicable regulations. Write-downs are provided for subsequent declines in value and are included in other non-interest expense along with other expenses related to maintaining the properties.

Potential problem loans consist of loans that are performing in accordance with contractual terms but for which management has concerns about the ability of an obligor to continue to comply with repayment terms because of the obligor’s potential operating or financial difficulties. Management monitors these loans closely and reviews their performance on a regular basis. At June 30, 2009 and December 31, 2008, the Corporation had $27.7 million and $50.2 million in loans of this type which are not included in either of the non-accrual or 90 days past due loan categories. At June 30, 2009, potential problem loans consisted of eight credit relationships. Of the total outstanding balance at June 30, 2009, 36.3% related to a customer in the credit collections industry, 26.0% related to four customers in the real estate lot development/single-family residential construction industry and 25.2% related to a customer in the energy industry. Weakness in these companies’ operating performance has caused the Corporation to heighten the attention given to these credits.

The after-tax impact (assuming a 35% marginal tax rate) of lost interest from non-performing loans was approximately $942 thousand and $1.6 million for the three and six months ended June 30, 2009, compared to $321 thousand and $606 thousand for the same periods in 2008.

The allowance for possible loan losses is a reserve established through a provision for possible loan losses charged to expense, which represents management’s best estimate of probable losses that have been incurred within the existing portfolio of loans. The allowance, in the judgment of management, is necessary to reserve for estimated loan losses and risks inherent in the loan portfolio. The Corporation’s allowance for possible loan loss methodology is based on guidance provided in SEC Staff Accounting Bulletin No. 102, “Selected Loan Loss Allowance Methodology and Documentation Issues” and includes allowance allocations calculated in accordance with SFAS No. 114, “Accounting by Creditors for Impairment of a Loan,” as amended by SFAS 118, and allowance allocations calculated in accordance with SFAS No. 5, “Accounting for Contingencies.” Accordingly, the methodology is based on historical loss experience by type of credit and internal risk grade, specific homogeneous risk pools, and specific loss allocations, with adjustments for current events and conditions. The Corporation’s process for determining the appropriate level of the allowance for possible loan losses is designed to account for credit deterioration as it occurs. The provision for possible loan losses reflects loan quality trends, including the levels of and trends related to non-accrual loans, past due loans, potential problem loans, criticized loans and net charge-offs or recoveries, among other factors. The provision for possible loan losses also reflects the totality of actions taken on all loans for a particular period. In other words, the amount of the provision reflects not only the necessary increases in the allowance for possible loan losses related to newly identified criticized loans, but it also reflects actions taken related to other loans including, among other things, any necessary increases or decreases in required allowances for specific loans or loan pools.

The provision for possible loan losses totaled $16.6 million and $26.2 million during the three and six months ended June 30, 2009, compared to $6.3 million and $10.3 million during the three and six months ended June 30, 2008. The increases in the provision for possible loan losses were partly due to higher levels of net charge-offs and an increase in classified loans related to the weaker economic conditions. The weak economic conditions have particularly affected the performance of many of the Corporation’s land development and 1-4 family residential construction credit relationships. Net charge-offs during the three and six months ended June 30, 2009 increased $4.0 million and $5.8 million compared to the same periods in 2008. As a percentage of average loans, net charge-offs increased 17 basis points and 12 basis points during the three and six month ended June 30, 2009 compared to the same periods in 2008. The increase in net charge-offs is reflective of the increase in classified assets related to the deterioration of economic conditions. The ratio of the allowance for possible loan losses to total loans increased 17 basis points from 1.25% at December 31, 2008 to 1.42% at June 30, 2009,

42

primarily to compensate for the increase in classified assets. Management believes the level of the allowance for possible loan losses continues to remain adequate. Should any of the factors considered by management in evaluating the adequacy of the allowance for possible loan losses change, the Corporation’s estimate of probable loan losses could also change, which could affect the level of future provisions for possible loan losses.

Capital and Liquidity

Capital. At June 30, 2009, shareholders’ equity totaled $1.8 billion compared to $1.8 billion at December 31, 2008 and $1.5 billion at June 30, 2008. In addition to net income of $82.8 million, other significant changes in shareholders’ equity during the first six months of 2009 included $50.6 million of dividends paid, $7.9 million in proceeds from stock option exercises and the related tax benefits of $606 thousand and $6.4 million related to stock-based compensation. Additionally, the Corporation issued/sold $1.6 million in common stock held in treasury to the Corporation’s 401(k) plan. During the second quarter of 2009, the Corporation began to issue shares of the Corporation’s common stock directly to the Corporation’s 401(k) plan in connection with matching contributions. Additionally, the 401(k) plan began to purchase shares of the Corporation’s common stock directly from the Corporation utilizing proceeds from dividends that plan participants elected to reinvest in the Corporation’s common stock. Previously, the Corporation contributed the matching contributions in cash, which, along with the proceeds from dividends on the Corporation’s common stock, were then utilized to purchase shares of the Corporation’s common stock on the open market.

The accumulated other comprehensive income/loss component of shareholders’ equity totaled a net, after-tax, unrealized gain of $122.0 million at June 30, 2009 compared to a net, after-tax, unrealized gain of $137.3 million at December 31, 2008. This fluctuation was primarily related to the after-tax effect of a change in the accumulated net gain/loss on effective cash flow hedges offset by the after-tax effect of a change in the unrealized gain/loss on securities available for sale during the first six months of 2009. Under regulatory requirements, amounts reported as accumulated other comprehensive income/loss related to securities available for sale, effective cash flow hedges and defined benefit post-retirement benefit plans do not increase or reduce regulatory capital and are not included in the calculation of risk-based capital and leverage ratios. Regulatory agencies for banks and bank holding companies utilize capital guidelines designed to measure Tier 1 and total capital and take into consideration the risk inherent in both on-balance sheet and off-balance sheet items. See Note 9 - Regulatory Matters in the accompanying notes to consolidated financial statements included elsewhere in this report.

The Corporation paid quarterly dividends of $0.42 and $0.43 per common share during the first and second quarters of 2009 and quarterly dividends of $0.40 and $0.42 per common share during the first and second quarters of 2008. This equates to a dividend payout ratio of 55.5% and 67.7% during the first and second quarters of 2009 and 44.6% and 47.1% during the first and second quarters of 2008.

From time to time, the Corporation’s board of directors has authorized stock repurchase plans. Stock repurchase plans allow the Corporation to proactively manage its capital position and return excess capital to shareholders. Shares purchased under such plans also provide the Corporation with shares of common stock necessary to satisfy obligations related to stock compensation awards. Under the most recent plan, which was approved on April 26, 2007, the Corporation was authorized to repurchase up to 2.5 million shares of its common stock from time to time over a two-year period in the open market or through private transactions. Under the plan, 404 thousand shares approved for repurchase were repurchased during the first quarter of 2008 at a total cost of $21.9 million. See Part II, Item 2 - Unregistered Sales of Equity Securities and Use of Proceeds, included elsewhere in this report, for details of stock repurchases during the quarter.

Liquidity. Liquidity measures the ability to meet current and future cash flow needs as they become due. The liquidity of a financial institution reflects its ability to meet loan requests, to accommodate possible outflows in deposits and to take advantage of interest rate market opportunities. The ability of a financial institution to meet its current financial obligations is a function of its balance sheet structure, its ability to liquidate assets, and its access to alternative sources of funds. The Corporation seeks to ensure its funding needs are met by maintaining a level of liquid funds through asset/liability management.

Asset liquidity is provided by liquid assets which are readily marketable or pledgeable or which will mature in the near future. Liquid assets include cash, interest-bearing deposits in banks, securities available for sale, maturities and cash flow from securities held to maturity, and federal funds sold and resell agreements.

Liability liquidity is provided by access to funding sources which include core deposits and correspondent banks in the Corporation’s natural trade area that maintain accounts with and sell federal funds to Frost Bank, as well as federal funds purchased and repurchase agreements from upstream banks and deposits obtained through financial intermediaries.

Since Cullen/Frost is a holding company and does not conduct operations, its primary sources of liquidity are dividends up-streamed from Frost Bank and borrowings from outside sources. Banking regulations may limit the amount of dividends that

43

may be paid by the Corporation’s bank subsidiary. See Note 9 - Regulatory Matters in the accompanying notes to consolidated financial statements included elsewhere in this report regarding such dividends. At June 30, 2009, Cullen/Frost had liquid assets, including unrestricted cash and securities purchased under resell agreements, totaling $68.0 million.

The liquidity position of the Corporation is continuously monitored and adjustments are made to the balance between sources and uses of funds as deemed appropriate. Management is not aware of any events that are reasonably likely to have a material adverse effect on the Corporation’s liquidity, capital resources or operations. In addition, management is not aware of any regulatory recommendations regarding liquidity, which if implemented, would have a material adverse effect on the Corporation.

The Corporation’s operating objectives include expansion, diversification within its markets, growth of its fee-based income, and growth internally and through acquisitions of financial institutions, branches and financial services businesses. The Corporation seeks merger or acquisition partners that are culturally similar and have experienced management and possess either significant market presence or have potential for improved profitability through financial management, economies of scale and expanded services. The Corporation regularly evaluates merger and acquisition opportunities and conducts due diligence activities related to possible transactions with other financial institutions and financial services companies. As a result, merger or acquisition discussions and, in some cases, negotiations may take place and future mergers or acquisitions involving cash, debt or equity securities may occur. Acquisitions typically involve the payment of a premium over book and market values, and, therefore, some dilution of the Corporation’s tangible book value and net income per common share may occur in connection with any future transaction.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The disclosures set forth in this item are qualified by the section captioned “Forward-Looking Statements and Factors that Could Affect Future Results” included in Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations of this report and other cautionary statements set forth elsewhere in this report.

Refer to the discussion of market risks included in Item 7A. Quantitative and Qualitative Disclosures About Market Risk in the 2008 Form 10-K. There has been no significant change in the types of market risks faced by the Corporation since December 31, 2008.

The Corporation utilizes an earnings simulation model as the primary quantitative tool in measuring the amount of interest rate risk associated with changing market rates. The model quantifies the effects of various interest rate scenarios on projected net interest income and net income over the next 12 months. The model measures the impact on net interest income relative to a base case scenario of hypothetical fluctuations in interest rates over the next 12 months. These simulations incorporate assumptions regarding balance sheet growth and mix, pricing and the repricing and maturity characteristics of the existing and projected balance sheet. The impact of interest rate derivatives, such as interest rate swaps, caps and floors, is also included in the model. Other interest rate-related risks such as prepayment, basis and option risk are also considered.

As of June 30, 2009, the model simulations projected that 100 and 200 basis point increases in interest rates would result in positive variances in net interest income of 1.0% and 2.0%, respectively, relative to the base case over the next 12 months, while a decrease in interest rates of 25 basis points would result in a negative variance in net interest income of 1.2% relative to the base case over the next 12 months. The likelihood of a decrease in interest rates beyond 25 basis points as of June 30, 2009 was considered remote given current interest rate levels. As of June 30, 2008, the model simulations projected that 100 and 200 basis point increases in interest rates would not result in any significant variance in net interest income relative to the base case over the next 12 months, while a decrease in interest rates of 100 basis points would result in a negative variance in net interest income of 0.7% relative to the base case over the next 12 months. The likelihood of a 200 basis point decrease in interest rates as of June 30, 2008 was considered to be remote given current interest rate levels.

During the fourth quarter of 2007, the Corporation entered into certain interest rate swap contracts that were designated as hedging instruments in cash flow hedges that effectively fixed the interest rates on $1.2 billion of variable-rate loans. These actions resulted in a decrease in the Corporation’s sensitivity to changes in interest rates during 2008. See Note 17 - Derivative Financial Instruments in the 2008 Form 10-K. The Corporation’s increased sensitivity to increases in interest rates during 2009 was primarily the result of growth in loans which diluted the neutralizing effect of the interest rate swaps. The Corporation’s increased sensitivity to decreases in interest rates during 2009 is primarily the result of projected pre-payments of mortgage-backed securities, which would then be reinvested at lower yields.

As of June 30, 2009, the effect of a 200 basis point increase in interest rates on the Corporation’s derivative holdings would result in a 2.2% negative variance in net interest income. The effect of a 25 basis point decrease in interest rates on the Corporation’s derivative holdings would result in a 0.6% positive variance in net interest income.

The effects of hypothetical fluctuations in interest rates on the Corporation’s securities classified as “trading” under SFAS 115, “Accounting for Certain Investments in Debt and Equity Securities,” are not significant, and, as such, separate quantitative disclosure is not presented.

Item 4. Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, an evaluation was carried out by the Corporation’s management, with the participation of its Chief Executive Officer and Chief Financial Officer, of the effectiveness of the Corporation’s disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures were effective as of the end of the period covered by this report. No change in the Corporation’s internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) occurred during the last fiscal quarter that materially affected, or is reasonably likely to materially affect, the Corporation’s internal control over financial reporting.
