The Subordinated Debentures may be redeemed, subject to approval by the Federal Reserve Bank, on any quarterly redemption date set forth in the agreements. The terms of the Trust Preferred Securities are identical to those of the Subordinated Debentures. The Trust Preferred Securities are subject to mandatory redemption upon repayment of the Subordinated Debentures at their stated maturity dates or earlier redemption in an amount equal to their liquidation amount plus accumulated and unpaid distributions to the date of redemption. The Company guarantees the payment of distributions and payments for redemption or liquidation of the Trust Preferred Securities to the extent of funds held by the Trusts. Subject to certain limitations, the Trust Preferred Securities qualify as tier 1 capital of the Parent Company under the Federal Reserve Board’s capital adequacy guidelines. Proceeds from the issuance of the Trust Preferred Securities were used to fund acquisitions.

In conjunction with the acquisition of MWFC, the Company acquired sponsorship of two wholly-owned business trusts, MWF Statutory Trust III and MWF Statutory Trust IV (collectively the "Trusts"), which were formed for the exclusive purpose of issuing an aggregate of $19,825 of 30-year floating rate mandatorily redeemable capital trust preferred securities ("Trust Preferred Securities") to third-party investors. The Trusts also issued, in aggregate, $614 of common equity securities to MWFC. Proceeds from the issuance of the Trust Preferred Securities and common equity securities were invested in 30-year junior subordinated deferrable interest debentures ("Subordinated Debentures") issued by MWFC.
