|The supervision and regulation of bank holding companies and their subsidiaries is intended primarily for the protection of depositors, the deposit insurance funds regulated by the FDIC and the banking system as a whole, and not for the protection of shareholders or creditors of bank holding companies. Bank regulatory agencies have broad enforcement power over bank holding companies and banks, including the power to impose substantial fines, operational restrictions and other penalties for violations of laws and regulations. The following description summarizes some of the laws to which the Company and its subsidiaries are subject. References to applicable statutes and regulations are brief summaries and do not claim to be complete. Management believes the Company is in compliance in all material respects with these laws and regulations. Changes in the laws, regulations or policies that impact the Company cannot necessarily be predicted, but they may have a material effect on the business and earnings of the Company.

|Regulatory Restrictions on Dividends -- It is the policy of the Federal Reserve Board that bank holding companies should pay cash dividends on common stock only out of income available over the past year, and only if prospective earnings retention is consistent with the holding company's expected future needs and financial condition. The policy provides that bank holding companies should not maintain a level of cash dividends that undermines the bank holding company's ability to serve as a source of strength to its banking subsidiary. Under Federal Reserve Board policy, a bank holding company is expected to act as a source of financial strength to its banking subsidiary and commit resources to their support.

|Safe and Sound Banking Practices -- Bank holding companies are not permitted to engage in unsafe and unsound banking practices. The Federal Reserve Board's Regulations for example, generally require a holding company to give the Federal Reserve Board prior notice of any redemption or repurchase of its own equity securities, if the consideration to be paid, together with the consideration paid for any repurchases or redemptions in the preceding year, is equal to 10% or more of the company's consolidated net worth. The Federal Reserve Board has broad authority to prohibit activities of bank holding companies and their non-banking subsidiaries which represent unsafe and unsound banking practices or which constitute violations of laws or regulations, and can assess civil money penalties for certain activities conducted on a knowing and reckless basis, if those activities caused a substantial loss to a depository institution.

|Capital Adequacy Requirements -- The Federal Reserve Board has adopted a system using risk-based capital guidelines to evaluate the capital adequacy of bank holding companies. Under the guidelines, specific categories of assets are assigned different risk weights, based generally on the perceived credit risk of the asset. These risk weights are multiplied by corresponding asset balances to determine a "risk-weighted" asset base. In addition to the risk-based capital guidelines, the Federal Reserve Board uses a leverage ratio as an additional tool to evaluate the capital adequacy of bank holding companies. Federal Reserve Board guidelines also provide that banking organizations experiencing internal growth or making acquisitions will be expected to maintain strong capital positions substantially above the minimum supervisory levels, without significant reliance on intangible assets. The leverage ratio is a company's Tier 1 capital divided by three-month average consolidated assets. See Note 17 on page 28 of the 2003 Annual Report, which is incorporated herein by reference for the Company's and Bank's capital ratios.

|Imposition of Liability for Undercapitalized Subsidiaries -- Bank regulators are required to take "prompt corrective action" to resolve problems associated with insured depository institutions whose capital declines below certain levels. In the event an institution becomes "undercapitalized," it must submit a capital restoration plan. The capital restoration plan will not be accepted by the regulators unless each company having control of the undercapitalized institution guarantees the subsidiary's compliance with the capital restoration plan up to a certain specified amount. Any such guarantee from a depository institution's holding company is entitled to a priority of payment in bankruptcy.

|Acquisitions by Bank Holding Companies-- The Bank Holding Company Act requires every bank holding company to obtain the prior approval of the Federal Reserve Board before it may acquire all or substantially all of the assets of any bank, or ownership or control of any voting shares of any bank, if after such acquisition it would own or control, directly or indirectly, more than 5% of the voting shares of such bank. In approving bank acquisitions by bank holding companies, the Federal Reserve Board is required to consider the financial and managerial resources and future prospects of the bank holding company and the banks concerned, the convenience and needs of the communities to be served, and various competitive factors.

|Control Acquisitions --The Change in Bank Control Act prohibits a person or group of persons from acquiring "control" of a bank holding company unless the Federal Reserve Board has been notified and has not objected to the transaction. Under a rebuttable presumption established by the Federal Reserve Board, the acquisition of 10% or more of a class of voting stock of a bank holding company with a class of securities registered under Section 12 of the Exchange Act, would, under the circumstances set forth in the presumption, constitute acquisition of control of the Company. In addition, any entity is required to obtain the approval of the Federal Reserve Board under the Bank Holding Company Act before acquiring 25% (5% in the case of an acquirer that is a bank holding company) or more of the Company's outstanding common stock, or otherwise obtaining control or a "controlling influence" over the Company

|Restrictions on Transactions with Affiliates and Insiders -- Transactions between the holding company and its subsidiaries, including the Bank, are subject to Section 23A of the Federal Reserve Act. In general, Section 23A imposes limits on the amount of such transactions, and also requires certain levels of collateral for loans to affiliated parties. It also limits the amount of advances to third parties which are collateralized by the securities or obligations of the Company or its subsidiaries. Affiliate transactions are also subject to Section 23B of the Federal Reserve Act which generally requires that certain transactions between the holding company and its affiliates be on terms substantially the same, or at least as favorable to the bank, as those prevailing at the time for comparable transactions with or involving other nonaffiliated persons.

|Insider loans --Restrictions on loans to directors, executive officers, principal shareholders and their related interests ("insiders") contained in the Federal Reserve Act and Regulation O apply to the Bank, its subsidiaries and the Company. These restrictions include limits on loans to one borrower and conditions that must be met before such a loan can be made. There is also an aggregate limitation on all loans to insiders and their related interests. These loans cannot exceed the institution's total unimpaired capital and surplus, and the FDIC may determine that a lesser amount is appropriate. Insiders are subject to enforcement actions for knowingly accepting loans in violation of applicable restrictions.

|Restrictions on Distribution of Subsidiary Bank Dividends and Assets-- Dividends paid by the Bank have been the Company's primary source of operating funds and are expected to be for the foreseeable future. Capital adequacy requirements serve to limit the amount of dividends that may be paid by the Bank. Under federal law, the Bank cannot pay a dividend if, after paying the dividend, it will be "undercapitalized." The FDIC may declare a dividend payment to be unsafe and unsound even though the Bank would continue to meet its capital requirements after the dividend. Because the Company is a legal entity separate and distinct from the Bank, the Company's right to participate in the distribution of assets of the Bank in

|The FDIC Improvement Act of 1991 (FDICIA)- The Bank, with total assets of more than $500 million must submit annual audit reports prepared by independent auditors to federal and state regulators. As allowed by regulations, the audit report of the Company is used to satisfy this requirement. Auditors must receive examination reports, supervisory agreements and reports of enforcement actions. In addition, financial statements prepared in accordance with generally accepted accounting principles, management's certifications concerning responsibility for the financial statements, internal controls and compliance with legal requirements designated by the FDIC, and an attestation by the auditor regarding the statements of management relating to the internal controls must be submitted. FDICIA also requires that independent audit committees be formed, consisting of outside directors only. The committees of institutions with assets of more than $3 billion must include members with experience in banking or financial management, must have access to outside counsel and must not include representatives of large customers.

|Community Reinvestment Act -- The Community Reinvestment Act of 1977 ("CRA") and attendant regulations are intended to encourage banks to help meet the credit needs of their service area, including low-and moderate-income neighborhoods, consistent with the safe and sound operations of the banks. These regulations also provide for regulatory assessment of a bank's record in meeting the needs of its service area when considering applications regarding establishing branches, mergers or other bank or branch acquisitions. Federal banking agencies make public a bank's performance rating under the CRA. In the case of a bank holding company, the CRA performance record of the bank(s) involved in the transaction are reviewed in connection with the filing of an application to acquire ownership or control of shares or assets of a bank or to merge with any other bank holding company.

|The Currency and Foreign Transactions Reporting Act, also known as the Bank Secrecy Act (BSA), and its implementing regulation, 31 CFR 103, is a tool the U.S. government uses to fight drug trafficking, money laundering, and other crimes. Congress enacted the BSA to prevent banks and other financial service providers from being used as intermediaries for, or to hide the transfer or deposit of money derived from, criminal activity. The Office of the Comptroller of the Currency (OCC) monitors national bank compliance with the BSA and 31 CFR 103.

|Since its passage, Congress has amended the BSA a number of times to enhance law enforcement effectiveness. The Anti-Drug Abuse Act of 1986, which included the Money Laundering Control Act of 1986 (MLCA), strengthened the government's ability to fight money laundering by making it a criminal activity. The Money Laundering Suppression Act of 1994 (Title IV of the Riegle-Neal Community Development and Regulatory Improvement Act of 1994) required regulators to develop enhanced examination procedures and increase examiner training to improve the identification of money laundering schemes in financial institutions.

|Today more than 170 crimes are listed in the federal money laundering statutes. They range from drug trafficking, gunrunning, murder for hire, fraud, acts of terrorism, and the illegal use of a wetlands. The list also includes certain foreign crimes. Therefore, a financial institution must educate its employees, understand its customers and their businesses, and have systems and procedures in place to distinguish routine transactions from ones that rise to the level of suspicious activity. The reporting and record keeping requirements of the BSA regulations create a paper trail for law enforcement to investigate money laundering schemes and other illegal activities. This paper trail operates to deter illegal activity and provides a means to trace movements of money through the financial system.

The Patriot Act contains sweeping anti-money laundering and financial transparency laws and requires various regulations, including standards for verifying customer identification at account opening, and rules to promote cooperation among financial institutions, regulators and law enforcement entities in identifying parties that may be involved in terrorism or money laundering.

|Financial Services Modernization Legislation. In November 1999, the GLB Act of 1999 was enacted. The GLB repeals provisions of the Glass-Steagall Act which restricted the affiliation of Federal Reserve member banks with firms "engaged principally" in specified securities activities, and which restricted officer, director, or employee interlocks between a member bank and any company or person "primarily engaged" in specified securities activities.  In addition, the GLB Act contains provisions that expressly preempt any state law restricting the establishment of financial affiliations, primarily related
to insurance. The general effect of the law is to establish a comprehensive framework to permit affiliations among commercial banks, insurance companies, securities firms, and other financial service providers by revising and expanding the Bank Holding Company Act framework to permit a holding company to engage in a full range of financial activities through a new entity known as a "financial holding company." "Financial activities" is broadly defined to include not only banking, insurance and securities activities, but also merchant banking and additional activities that the Federal Reserve Board, in consultation with the Secretary of the Treasury, determines to be financial in nature, incidental to such financial activities, or complementary activities that do not pose a substantial risk to the safety and soundness of depository institutions or the financial system.  The GLB Act also permits national banks to engage in expanded activities through the formation of financial subsidiaries. A national bank may have a subsidiary engaged in any activity authorized for national banks directly or any financial activity, except for insurance underwriting, insurance investments, real estate investment or development, or merchant banking, which may only be conducted through a subsidiary of a financial holding company. Financial activities include all activities permitted under new sections of the Bank Holding Company Act or permitted by regulation.

|Fair and Accurate Credit Transactions ("FACT")The FACT Act includes many provisions concerning national credit reporting standards, and permits consumers, including the customers of the Company, to opt out of information sharing among affiliated companies for marketing purposes. The FACT Act also requires financial institutions, including banks, to notify their customers if they report negative information about them to credit bureaus or if the credit that is granted to them is on less favorable terms than are generally available. Banks also must comply with guidelines to be established by their federal banking regulators to help detect identity theft.

|Sarbanes-Oxley Act. On July 30, 2002. The stated goals of the SOA are to increase corporate responsibility, to provide for enhanced penalties for accounting and auditing improprieties at publicly traded companies and to protect investors by improving the accuracy and reliability of corporate disclosures pursuant to the securities laws. The SOA includes very specific additional disclosure requirements and new corporate governance rules, requires the SEC and securities exchanges to adopt extensive additional disclosure, corporate governance and other related rules and mandates further studies of certain issues by the SEC and the Comptroller General. The SOA represents significant federal involvement in matters traditionally left to state regulatory systems, such as the regulation of the accounting profession, and to state corporate law, such as the relationship between a board of directors and management and between a board of directors and its committees. The SOA addresses, among other matters, audit committees; certification of financial statements by the chief executive officer and chief financial officer; the forfeiture of bonuses or other incentive-based compensation and profits from the sale of an issuer's securities by directors and senior officers in the twelve month period following initial publication of any financial statements that later require restatement; a prohibition on insider trading during pension plan black out periods; disclosure of off-balance sheet transactions; a prohibition on certain loans to directors and officers; expedited filing requirements for Forms 4; disclosure of a code of ethics and filing a Form 8-K for a change or waiver of such code; "real time" filing of periodic reports; the formation of a public accounting oversight board; auditor independence; and various increased criminal penalties for violations of securities laws. The SEC has enacted rules to implement various provisions of SOA. The federal banking regulators have adopted generally similar requirements concerning the certification of financial statements.

|Method of Accounting.

|Minimum Tax.The Internal Revenue Code of 1986 imposes an alternative minimum tax ("AMT") at a rate of 20% on a base of regular taxable income plus certain tax preferences ("alternative minimum taxable income" or "AMTI"). The AMT is payable to the extent such AMTI is in excess of an exemption amount. Net operating losses can offset no more than 90% of AMTI. Certain payments of alternative minimum tax may be used as credits against regular tax liabilities in future years. The Company is subject to the AMT but has no such amounts available as credits for carryover.

|The SEC defines "critical accounting policy" as, "most important to the portrayal of the company's financial condition and results, and it requires management's most difficult, subjective, or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain."  Management considers the "Allowance for Loan Losses" as the Company's critical accounting policy.

|The Company's Chief Executive Officer and Chief Financial Officer have concluded, based on their evaluation as of December 31, 2004, that the Company's disclosure controls and procedures (as defined in Securities Exchange Act Rules 13a-14(c) and 15d-14(c)) are effective to ensure that information required to be disclosed in the reports that the Company files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission's rules and forms. There have been no changes in the Company's internal control over financial reporting that occurred during the fourth quarter of 2004, that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.
