Pinnacle Financial Partners Issues $30 Million in Trust Preferred Securities

Nashville, Tenn., Oct. 31, 2007 - Pinnacle Financial Partners Inc. (Nasdaq/NGS: PNFP), the holding company of Pinnacle National Bank, today completed the private placement of $30 million in trust preferred securities through an affiliated statutory trust.

The trust preferred securities will be payable in 2037 and will bear interest at a quarterly floating rate of three-month LIBOR plus 2.85 percent. Pinnacle anticipates that substantially all of the proceeds will be used in connection with its anticipated merger with Mid-America Bancshares Inc.

FTN Financial Capital Markets acted as the placement agent for Pinnacle in the transaction.

The firm began operations in a single downtown Nashville location in October 2000 and has since grown to $2.3 billion in assets. Earlier this year, Pinnacle launched an expansion into Knoxville, another high growth MSA. The addition of Mid-America will make Pinnacle the second largest bank holding company headquartered in Tennessee, with 31 offices in the Nashville area.
