SHAREHOLDERS APPROVE COMBINATION OF PINNACLE FINANCIAL PARTNERS and MID-AMERICA BANCSHARES, INC.

Nashville, Tenn., Nov. 27, 2007 Shareholders of Pinnacle Financial Partners Inc. (Nasdaq/NGS: PNFP) and Mid-America Bancshares Inc. today voted overwhelmingly in favor of the proposed merger of Pinnacle and Mid-America, parent of Middle Tennessee's PrimeTrust Bank and Bank of the South.

The transaction is expected to close on Nov. 30, 2007, making Pinnacle Tennessee's second-largest bank holding company with $3.7 billion in assets and 33 offices in attractive Middle Tennessee markets.

Terms of the agreement call for each share of Mid-America to receive 0.4655 Pinnacle shares and $1.50 in cash which results in the transaction approximating 90 percent paid in PNFP shares and 10 percent paid in cash.

"This is a significant milestone for all of us at Pinnacle," said Pinnacle President and CEO Terry Turner. "We believe all of our constituencies will benefit from this merger - associates, clients, communities and shareholders."

Pinnacle anticipates PrimeTrust and Bank of the South will use the Pinnacle name by March 2008 when the operations of the three companies are combined. In the interim, clients should continue to bank with PrimeTrust or Bank of the South as they always have, using their existing checks, ATM/debit cards, payment coupons, etc. until the companies combine their operations.

When the operations of the three institutions are combined, Pinnacle's existing clients will gain the convenience of another 13 locations, including offices in Dickson, Cheatham and Wilson counties, which are new to Pinnacle's footprint. PrimeTrust and Bank of the South clients will have available to them a wider array of services, including personal trust, investment and insurance. Pinnacle will also provide its sophisticated suite of Treasury Management services to business clients of PrimeTrust and Bank of the South.

Pinnacle Financial Partners provides a full range of banking, investment and insurance products and services designed for small- to mid-sized businesses and their owners, real estate professionals and individuals interested in a comprehensive relationship with their financial institution. Comprehensive wealth management services, such as financial planning and trust, help clients increase, protect and distribute their assets. The firm also has a well-established expertise in commercial real estate.
