If any other business is brought before the Special Meeting, this form will be voted by the Trustee in a manner intended to represent the best interest of participants and beneficiaries of the Plan. At the present time, IBKC knows of no other business to be brought before the Special Meeting.

The Trustee is hereby authorized and directed to vote my proportionate interest in IBKC common stock in my Plan account as indicated on the reverse side. If I do not return this form in a timely manner, no instruction is specified or the form is returned signed without instruction, shares representing my interest in the Plan will be voted in proportion to the manner in which other participants have voted their interests, subject to the determination that such a vote is for the exclusive benefit of Plan participants and beneficiaries.
