The Trust Preferred Securities bear a 10 7/8% fixed rate of interest payable semi- annually. GBB Capital III used the proceeds from the sale of the trust preferred securities to purchase junior subordinated deferrable interest debentures of Greater Bay Bancorp. Greater Bay Bancorp intends to invest a portion of the net proceeds in one or more of its subsidiary banks to increase their capital levels and intends to use the remaining net proceeds for general corporate purposes. Under applicable regulatory guidelines, Greater Bay Bancorp expects that a certain portion of the Trust Preferred Securities will qualify as Tier I Capital, and the remaining portion will qualify as Tier II Capital.
