State Farm^® Announces Intent to Vote in Favor of Management of Phoenix Companies Inc.^®

Bloomington, Ill., March 3 /PRNewswire/ — In light of the magnitude of business dealings between State Farm and the Phoenix Companies, Inc. (“Phoenix”), State Farm deemed it appropriate to distribute this News Release in advance of the May 2, 2008 annual meeting of the Phoenix shareholders.

State Farm has a strategic alliance with Phoenix to distribute advanced market life insurance products. This alliance has been operating since 2001. A key to the alliance’s on-going success is stability and continuity in both the service and products provided by Phoenix to State Farm’s distribution system. Our ongoing confidence in the current Phoenix management structure is based in large part upon their understanding of this issue and how their actions have demonstrated the ability to meet our expectations. Any key leadership changes could negatively impact the stability in the alliance between the two companies.
