ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT CREATION OF A DIRECT FINANCIAL OBLIGATION OR AN OBLIGATION UNDER AN OFF-BALANCE SHEET ARRANGEMENT OF A REGISTRANT Introduction On September 16, 2004, Mercantile Bank Corporation ("Mercantile") entered into several agreements providing for the private sale of Series A and Series B Floating Rate Preferred Securities by its newly formed Delaware trust subsidiary, Mercantile Bank Capital Trust I (the "Trust") to STI Investment Management, Inc., a Delaware corporation (the "Purchaser"). The sale of the Series A Preferred Securities to the Purchaser for $16,000,000 was completed on September 16, 2004. The sale of the Series B Preferred Securities to the Purchaser for $16,000,000 was completed on December 10, 2004. The agreements also provide for the Trust to sell $495,000 of Series A and Series B Common Securities to Mercantile. The sale of the $495,000 of Series A Common Securities to Mercantile was completed on September 16, 2004; and the sale of the $495,000 of Series B Common Securities was completed on December 10, 2004. The proceeds of the Series A Preferred Securities and the Series A Common Securities were used by the Trust on September 16, 2004 to purchase $16,495,000 of Series A Floating Rate Notes that were issued by Mercantile on September 16, 2004. The proceeds of the Series B Preferred Securities and the Series B Common Securities were used by the Trust on December 10, 2004 to purchase $16,495,000 of Series B Floating Rate Notes that were issued by Mercantile on December 10, 2004. Mercantile used $16,000,000 of the proceeds of its Series A Floating Rate Notes to finance the redemption on September 17, 2004 of the $16,000,000 of 9.60% Cumulative Preferred Securities issued in 1999 by its business trust subsidiary, MBWM Capital Trust I (Nasdaq symbol "MBWMP"). Mercantile expects to use the $16,000,000 proceeds of its Series B Floating Rate Notes to increase its capital and for general corporate purposes. The principal agreements that Mercantile has entered into in connection with this transaction were described in Mercantile's current report on Form 8-K dated September 21, 2004, that was filed with the Securities and Exchange Commission to report Mercantile's entry into the agreements and issuance of the Series A Floating Rate Preferred and Common Securities and the Series A Floating Rate Notes (the "Series A Form 8-K"). Those descriptions, amended and supplemented to reflect issuance of the Series B securities on December 10, 2004, are set forth below. Junior Subordinated Indenture On September 16, 2004, Mercantile entered into a Junior Subordinated Indenture (the "Indenture") with Wilmington Trust Company as trustee. The Indenture provides for the issuance by Mercantile of Series A and Series B Floating Rate Junior Subordinated 2 Notes due 2034 (the "Floating Rate Notes") aggregating $32,990,000 in principal amount. Each of the two Series of the Floating Rate Notes is in the principal amount of $16,495,000. The Floating Rate Notes bear interest at the three-month LIBOR rate plus 2.18%. Interest is payable on each January 18, April 18, July 18 and October 18. The interest rate for each series of the Floating Rate Notes adjusts every three months. The initial rate for the Series A Floating Rate Notes was 4.06% per annum. The initial rate for the Series B Floating Rate Notes is 4.64% per annum. Under the Indenture, Mercantile has the option, as long as it is not in default under certain specified provisions of the Indenture, at any time and from time to time, to defer the payment of interest on the Floating Rate Notes for up to twenty consecutive quarterly interest payment periods. During any such extension period, or while an event of default exists under the Indenture, the Indenture imposes restrictions on Mercantile's ability to declare or pay dividends or distributions on, or to redeem, purchase, acquire or make a liquidation payment with respect to, any of its capital stock, or to make payments of principal, interest or premium on, or repay, repurchase or redeem, any debt securities it may issue that rank equal or junior to the Floating Rate Notes. The Floating Rate Notes, for each series, mature 30 years after their date of issuance, and can be redeemed in whole or in part by Mercantile, at its option, at 100% of their principal amount and accrued and unpaid interest, at any time after the fifth anniversary of the first interest payment date. Mercantile may also redeem the Floating Rate Notes in full, at its option, at 100% of their principal amount and accrued and unpaid interest during the continuance of certain "capital disqualification events," "investment company events" or "tax events" specified in the Indenture. The payment of principal and interest on the Floating Rate Notes is subordinate and subject to the right of payment of all Senior Debt of Mercantile as provided for in the Indenture. The Floating Rate Notes are issuable in registered form in minimum denominations of $100,000 and in integral multiples of $1,000. The holders of 25% or more of the outstanding principal amount of a series of the Floating Rate Notes, or the trustee for such holders, may by notice to Mercantile (and in some cases also to the trustee) declare the principal amount of all of the Floating Rate Notes of that series due and payable immediately upon the occurrence of certain events of default specified in the Indenture. These events of default include (i) failure to pay any interest when due following the nonpayment of any such interest for twenty or more consecutive quarterly interest payment periods, and (ii) certain acts of Mercantile or the entry of a specified court order regarding Mercantile, relating to bankruptcy, insolvency, reorganization, appointment of a receiver or liquidator, or similar matters. In some cases the holders of at least 25% of the liquidation amount of the Preferred Securities of the Trust that holds the series of Floating Rate Notes may have rights to accelerate the maturity of the corresponding series of Floating Rate Notes, if upon the occurrence of a specified event of default, the holders of the Floating Rate Notes do not take action to do so. 3 The Indenture provides for the payment of reasonable compensation of the trustee under the Indenture and of its expenses. It also provides for Mercantile's indemnification of the trustee and its affiliates, and their officers, directors, shareholders, agents, representatives and employees against loss, damage, and other liabilities relating to the trust or performance of its duties. On September 16, 2004, Mercantile issued $16,495,000 of the Series A Floating Rate Notes, and on December 10, 2004 Mercantile issued $16,495,000 of the Series B Floating Rate Notes. In each case, the Floating Rate Notes were issued to Wilmington Trust Company, as Property Trustee under the Amended and Restated Trust Agreement dated September 16, 2004 described below, and Mercantile received payment of $16,495,000 for each series of Floating Rate Notes. Amended and Restated Trust Agreement On September 16, 2004, Mercantile entered into an Amended and Restated Trust Agreement for the Trust among Mercantile, as Depositor, Wilmington Trust Company, as Property Trustee, Wilmington Trust Company, as Delaware Trustee, and Gerald R. Johnson, Jr., Michael H. Price, and Charles E. Christmas, as Administrative Trustees (the "Trust Agreement"). Each of the Administrative Trustees is an executive officer of Mercantile. The Trust Agreement provides for the issuance of two classes of Trust Securities. These two classes are Floating Rate Preferred Securities ('Preferred Securities") and Floating Rate Common Securities ("Common Securities"). Each class of Trust Securities includes two series, a Series A and a Series B. Each series of Preferred Securities has an aggregate liquidation amount of $16,000,000; and each series of Common Securities has an aggregate liquidation amount of $495,000. The Trust Agreement provides for distributions to be paid on the Series A and B Preferred Securities and the Series A and B Common Securities, based on the liquidation amount of the outstanding Trust Securities, at the same rates and times as interest is payable on the Floating Rate Notes issued by Mercantile to the Property Trustee under the Trust. Each Trust Security has a liquidation amount of $1,000. The Preferred Securities are issued in minimum denominations of $100,000 of liquidation amount, and integral multiples of $1,000. Maturity, redemption, and acceleration features for the Trust Securities correspond with those of the Floating Rate Notes. Payment of distributions on, and the redemption price and liquidation distributions on the Common Securities is subordinated to the payment of such amounts on the Preferred Securities. The Trust Agreement provides for the payment of reasonable compensation of the trustees and payment of their expenses. It also provides for Mercantile's indemnification of each trustee and its affiliates, and their officers, directors, shareholders, agents, representatives and employees, against loss, damage, and other liabilities relating to the Trust or performance of a trustee's duties. 4 On September 16, 2004, the Trust sold $495,000 of Series A Common Securities to Mercantile and $16,000,000 of Series A Preferred Securities to the Purchaser.
