These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the assets available for benefits of the Plan at December 31, 2003 and 2002, and the changes in its assets available for benefits for the year ended December 31, 2003, in conformity with U.S. generally accepted accounting principles. Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental Schedule of Assets (Held at End of Year) as of December 31, 2003, is presented for the purpose of additional analysis and is not a required part of the financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in our audits of the financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole. /s/ Ernst & Young Detroit, Michigan June 25, 2004 1 Citizens Banking Corporation Amended And Restated Section 401(k) Plan Statements of Assets Available for Benefits DECEMBER 31 2003 2002 ------------ ------------ ASSETS Investments, at fair value: Common stock: Citizens Banking Corporation $ 43,051,504 $ 34,788,747 Mutual funds 83,033,699 66,894,718 Money market account 7,631,595 8,901,205 Loans to participants 3,151,548 3,358,984 ------------ ------------ Assets available for benefits $136,868,346 $113,943,654 ============ ============ See accompanying notes. 2 Citizens Banking Corporation Amended and Restated Section 401(k) Plan Statement of Changes in Assets Available for Benefits Year ended December 31, 2003 ADDITIONS Investments income: Dividends: Citizens Banking Corporation $ 1,551,776 Other 1,159,121 Interest income 195,486 ------------ Total investment income 2,906,383 Contributions: Employer 3,033,801 Employee 6,257,940 ------------ 9,291,741 DEDUCTIONS Benefit payments to participants 15,333,106 Management fees 63,109 ------------ 15,396,215 Net realized and unrealized appreciation in fair value of investments (Note 3) 26,122,783 ------------ Net increase 22,924,692 Assets available for benefits at beginning of year 113,943,654 ------------ Assets available for benefits at end of year $136,868,346 ============ See accompanying notes. 3 Citizens Banking Corporation Amended and Restated Section 401(k) Plan Notes to Financial Statements December 31, 2003 and 2002 1. DESCRIPTION OF THE PLAN The following description provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. The Citizens Banking Corporation Amended and Restated Section 401(k) Plan (the Plan) is a defined contribution plan which includes a 401(k) salary deferral feature. The Plan covers substantially all employees of Citizens Banking Corporation (the Corporation) and its banking subsidiaries. Effective January 2001, the plan was amended to reduce the hours of required service to become eligible. Salaried employees are eligible for the Plan on the first business day of the calendar quarter coincident with or following their date of hire. Additionally, hourly employees are eligible for the Plan on the first business day of the month coincident with or next following the completion of ninety consecutive days of employment with the Corporation in which the employee is credited with at least 180 hours of credited service. If an hourly employee fails to be credited with at least 180 hours of credited service in the first ninety days of employment, he shall commence participation in the Plan on the first day of the month following any calendar quarter in which he is credited with at least 180 hours of credited service. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA). In 2003 and 2002, participants were able to contribute up to 50% of their annual salary, not to exceed the annual IRS limitation of the current year ($12,000 and $11,000 for 2003 and 2002, respectively). On an after-tax basis employees may contribute up to 10% of their compensation. The Corporation will match the participant's pre-tax contribution up to 6% of the participant's compensation (includes regular base salary or wages, commissions, overtime, shift premiums, incentive pay and referral pay). The Corporation will match 100% on the first 3% of pre-tax salary deferral and 50% on the next 3% of pre-tax salary deferral, for a total of a 75% match on a 6% pre-tax salary deferral. In addition, a retiree medical savings account was established for each participant. One third of the employer matching contribution is automatically directed into this account. Employees may not borrow against any monies residing in this account. Participants are immediately vested in their contributions and the Corporation's matching contributions plus actual earnings thereon. The benefit to which a participant is entitled is the 4 Citizens Banking Corporation Amended and Restated Section 401(k) Plan Notes to Financial Statements(continued) 1. DESCRIPTION OF THE PLAN (CONTINUED) benefit that can be provided from the participant's account. Participants direct the investment of their accounts, inclusive of the employer contribution balance, among the investments offered by the Plan. Participants may borrow from their fund accounts a minimum of $1,000 up to a maximum equal to the lesser of $50,000 or 50% of their vested account balance. Loan terms range from 1-5 years or up to 15 years for the purchase of a primary residence. The loans are secured by the balance in the participant's account and bear interest at a rate commensurate with the prime rate plus 1%. Principal and interest is paid ratably through bi-weekly payroll deductions. On termination of service, death, disability, or retirement, the participant will elect to receive, defer, or rollover a single lump-sum amount equal to the vested value of his or her account. All administrative expenses are paid by the Corporation except for specialized fees charged to individual participants. Although it has not expressed any intent to do so, the Corporation has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. Prior year amounts may have been reclassified to conform with current year presentation. 2. SIGNIFICANT ACCOUNTING POLICIES VALUATION OF INVESTMENTS Investments are stated at aggregate fair value. Securities traded on a national securities exchange are valued at the last reported sales price on the last business day of the year; investments traded in the over-the-counter market and listed securities for which no sale was reported on that date are valued at the average of the last reported bid and ask prices. The shares of registered investment companies are valued at quoted market prices which represent the net asset values of shares held by the Plan at year-end. The participant loans are valued at their outstanding balances, which approximate fair value. Purchases and sales are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. 5 Citizens Banking Corporation Amended and Restated Section 401(k) Plan Notes to Financial Statements(continued) 2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) USE OF ESTIMATES The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. 3. INVESTMENTS During 2003, the Plan's investments (including investments purchased, sold as well as held during the year) appreciated in fair value as determined by quoted market prices as follows: NET REALIZED AND UNREALIZED APPRECIATION IN FAIR VALUE OF INVESTMENTS ----------------------- Citizens Banking Corporation Common Stock $10,837,697 Mutual funds 15,285,086 ----------- $26,122,783 =========== Investments that represent 5% or more of fair value of the Plan's net assets are as follows: DECEMBER 31 2003 2002 ----------- ----------- **Citizens Banking Corporation Common Stock $43,051,504 $34,788,747 **Golden Oak Prime Obligation Class A 7,631,595 8,901,205 **Golden Oak Intermediate Income Fund 8,154,891 8,370,170 **Golden Oak Small Capital Value Fund 7,116,826 6,063,568 **Invesco Total Return Fund 11,876,986 * Janus Advisor International Retirement Class Fund 6,898,991 * **Invesco Balanced Fund * 12,477,960 * Investment does not represent 5% or more of fair value of the Plan's net assets. ** Party-in-interest. 6 Citizens Banking Corporation Amended and Restated Section 401(k) Plan Notes to Financial Statements(continued) 3. INVESTMENTS (CONTINUED) The Plan invests certain fund assets in the Golden Oak series of mutual funds. CB Capital Management, Inc., a subsidiary of Citizens Banking Corporation, serves as the investment advisor to these funds. The mutual fund portfolios were established pursuant to the provisions of the Investment Company Act of 1940. Investments within these portfolios were made in accordance with the applicable Department of Labor rules and regulations concerning the investment of qualified plan assets into mutual funds wherein the investment advisor to the portfolio is a party-in-interest with respect to the plan.

INCOME TAX STATUS The Plan has received a determination letter from the Internal Revenue Service dated August 20, 2002 stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the Code) and, therefore, the related trust is exempt from taxation. Subsequent to determination by the Internal Revenue Service, the Plan was amended. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan Administrator believes the Plan is operating in compliance with the applicable requirements of the Code and, therefore believes that the Plan, as amended, is qualified and the related trust is tax exempt. 7 Citizens Banking Corporation Amended and Restated Section 401(k) Plan Notes to Financial Statements(continued) 5.

RISKS AND UNCERTAINTIES The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants' account balances and the amounts reported in the statements of assets available for benefits. 9 SUPPLEMENTAL SCHEDULE Citizens Banking Corporation Amended and Restated Section 401(k) Plan EIN: 38-2378932 Plan Number: 002 Schedule H, Line 4i -- Schedule of Assets (Held at End of Year) December 31, 2003 DESCRIPTION OF INVESTMENT INCLUDING MATURITY DATE, RATE OF IDENTITY OF ISSUE, BORROWER, INTEREST, COLLATERAL, PAR OR CURRENT LESSOR OR SIMILAR PARTY MATURITY VALUE COST VALUE ---------------------------- -------------------------------- ------------- --------------- Common Stock: *Citizens Banking Corporation 1,315,755 Shares $ 43,051,504 ------------- Total Common Stock $ 43,051,504 Mutual Funds: *Golden Oak Diversified Growth Fund 720,441 Units $ 5,662,670 *Golden Oak Intermediate Income Fund 782,619 Units 8,154,891 *Golden Oak Value Portfolio Fund 768,356 Units 6,523,342 *Golden Oak Small Capital Fund 607,756 Units 7,116,826 *Golden Oak International Equity Fund 146,471 Units 1,121,966 AIM Mid-Cap Equity Fund 100,027 Units 2,692,725 American Balanced Fund 164,564 Units 2,845,314 American Growth Fund 270,603 Units 6,640,595 American Washington Mutual Investors Fund 63,678 Units 1,832,653 Fidelity Advisor Mortgage Securities Fund 374,081 Units 4,197,193 Fidelity Advisor Small Cap Fund T 43,918 Units 875,726 *Invesco Small Company Growth Fund 463,809 Units 5,157,560 *Invesco Total Return Fund 496,115 Units 11,876,986 Janus Mid-Cap Value Investor Fund 192,516 Units 3,925,395 Janus Advisor International Retirement Class Fund 284,260 Units 6,898,991 State Street Global Advisors S&P 500 Index Fund 353,570 Units 6,491,554 Templeton Foreign Fund 1,019,312 ------------- Total Mutual Funds 95,800 Units $ 83,033,699 Money Market Account: *Golden Oak Prime Obligation Class A $7,631,595 principal amount $ 7,631,595 ------------- Total Money Market Account $ 7,631,595 *Participant Loans Interest rate range: 5.0% - 10.5%; with various maturity dates $ 3,151,548 ------------- ------------- $ -- $ 136,868,346 ============= ============= *Party-in-interest.
