MEMPHIS, TN - Business Ethics magazine's list of the 100 Best Corporate Citizens includes First Horizon National Corp. for the third consecutive year. The closely watched survey has gained national recognition as an indicator of best practices in the area of corporate social responsibility.

"Trust is the foundation of the financial services business, so being recognized as one of the nation's best corporate citizens is a great honor for us," said Ken Glass, First Horizon's president, chairman and CEO. "In today's environment businesses are being scrutinized, and people want to know that the companies they choose to do business with and work for are operating in an ethical way. It is an honor for us to be included on this list with great companies who share our commitment to honest business practices."

Marjorie Kelly is editor of Business Ethics magazine. "What distinguishes the 100 Best Corporate Citizens from their peers is a commitment to higher standards," she said. "The list represents the top ten percent of Russell 1000 firms when it comes to corporate social responsibility - those that perform to a higher standard in serving a variety of stakeholders with excellence and integrity."

The 100 Best Corporate Citizens list appears in the Spring 2005 issue of Business Ethics magazine and on its Web site at www.business-ethics.com.
