The Capital Securities were sold pursuant to an Underwriting Agreement dated August 13, 2008 by and among TCF, the Trust and RBC Capital Markets Corporation, for itself and as representative of the several underwriters named therein (the “Underwriting Agreement”). TCF and the Trust also granted the underwriters a 30 day over-allotment option to purchase up to an additional $15,000,000 aggregate liquidation amount of the Capital Securities. TCF fully and unconditionally guaranteed payment of the Capital Securities on a subordinated basis and to the extent the Trust has funds available for payment pursuant to a Guarantee Agreement dated August 19, 2008 (the “Guarantee”) between TCF and Wilmington Trust Company (“Wilmington”), as Guarantee Trustee. The terms of the Capital Securities are set forth in the Amended and Restated Trust Agreement dated August 19, 2008 by and among TCF, Wilmington, the Administrative Trustees named therein and the Several Holders named therein (the “Trust Agreement”). The Notes were issued pursuant to an Indenture dated August 19, 2008 by and between TCF and Wilmington as supplemented by the Supplemental Indenture of the same date (the “Supplemental Indenture”).
