TierOne Bank's Transaction with Great Western Bank Expected to be Completed in Early 2010

The decision to reschedule the anticipated transaction closing date was made primarily to allow additional time to complete the on-going regulatory approval process.

Under the terms of the transaction, Great Western Bank will assume approximately $1.1 billion in deposits. The Bank will transfer or sell to Great Western Bank approximately $800.0 million in loans, $20.0 million in real estate and other assets and the balance in cash or securities less a $55.0 million deposit premium paid. Upon completion of the transaction, TierOne Bank will have 37 banking offices located in Nebraska, Iowa and Kansas. The closing of the transaction is subject to customary conditions precedent, including regulatory approval, several of which conditions are beyond the Company's ability to control. The Company cannot provide assurance that the conditions precedent will be satisfied.
