Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

On January 19, 2010, the Compensation Committee of the Board of Directors of the Company took certain actions related to the compensation of executive officers who are named in the executive compensation disclosures of the Company’s 2009 proxy statement (“2008 Named Executive Officers”), and for William C. (B.J.) Losch III, the Company’s principal financial officer since January 5, 2009. Mr. Losch and the 2008 Named Executive Officers are referred to in this Report as senior executive officers, or “SEOs.” Among other things, the Committee set SEO salary rates for 2010. The cash salaries of the SEOs were not changed from 2009 rates, but a new supplemental form of salary, Salary Stock Units (“SSUs”), was approved for SEOs for 2010.

Annualized salary rates effective January 1, 2010 for the SEOs are set forth in Exhibit 10.1 to this Report, which Exhibit is incorporated herein by this reference. The SSU rates established for SEOs partially is a response to substantial new restrictions upon compensation imposed by the U.S. Department of the Treasury under its Troubled Asset Relief Program, or TARP. As long as the Treasury’s preferred stock investment in the Company remains outstanding, for SEOs in 2010 the TARP rules prohibit cash bonuses entirely and limit equity awards to about one-third of total compensation, making salary the largest component of direct compensation. In prior years the compensation mix for SEOs generally has been heavily weighted in favor of bonus opportunity and equity awards, so the TARP rules required a restructuring of the mix of compensation components. The SSU rates for SEOs were established as part of that restructuring. The effect of the restructuring should not result in an increase in total annual direct compensation opportunity for any of the SEOs and should provide a larger percentage of compensation having a substantial direct link to the Company’s stock price.

SSUs are a supplemental form of salary subject to the terms, conditions, and limitations of the Salary Stock Unit Program. Among other things, for the SEOs the SSU Program provides that: (a) SSUs are credited each payroll period based on the value of the Company’s stock at the time of crediting; (b) SSUs credited in 2010 will be settled in cash early in March and September, 2011 based on the value of the Company’s stock at those times; and (c) SSUs will be treated as base salary for some purposes under other plans and programs, but not for all purposes. For SSU participants generally, but not for the SEOs, the SSU program provides for cash settlement of 2010 units in mid-2012 and requires that the SSU recipient be employed by the Company continuously until the SSUs are paid. However, the Company believes that the TARP rules presently do not allow the Company to impose a service-vesting requirement upon the SEOs listed above.

Salary rates are subject to adjustment, and the SSU Program is subject to amendment or termination, by the Compensation Committee at any time.

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year

Amendment of Bylaws

On January 19, 2010, the Company’s Board of Directors amended Section 2.4 of the Company’s Bylaws. The amendment was effective immediately.

The amendment removed a provision which specified that shareholders elect directors by plurality vote at the annual meeting. Accordingly, at any given meeting in the future directors will be elected if they obtain that vote level required by applicable Tennessee law at that time or by the Company’s charter.
