ITEM 1.01.  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On February 22, 2005, the Compensation Committee of the Board of Directors of
the registrant took certain actions which resulted in the grant, creation, or
supplement of the following compensatory agreements or arrangements with
executive officers of the registrant:

       Performance Accelerated Restricted Stock Award Program (PARSAP)
       (formerly known as TARSAP)

       Acting under authority delegated to it under the 1992 Restricted Stock
       Incentive Plan (which was shareholder-approved), the Committee provided
       that a portion of PARSAP shares having the 2002-2004 performance period
       be withheld by the registrant to the extent necessary to cover
       withholding taxes related to vesting of such awards. In addition, the
       Committee provided that all or a portion of PARSAP shares related to the
       2002-2004 performance period be deferred to the extent necessary to
       comport with Section 162(m) of the Internal Revenue Code of 1986, as
       amended.

       Long-Term Incentive Program (LTIP) Awards

       Acting under authority delegated to it under the 2003 Equity Compensation
       Plan (which was shareholder-approved), the Committee combined two years
       of the 2004 LTIP awards (with a performance period of 2004-2006) with the
       2005 LTIP awards. In connection with that action, the Committee limited
       the amount payable under the 2004 LTIP to a single-year amount and
       granted 2005 LTIP awards with both a two-year performance period (2005-
       2006) and a three-year performance period (2005-2007).


       Salary and Annual Bonus Action

       The Committee approved the salaries for the executive officers of the
       Company related to the year 2005, which range from $221,000 to $916,000.

       The Committee approved annual cash bonuses of the executive officers of
       the Company for 2004: J. Kenneth Glass ($285,000), Gerald L. Baker
       ($3,651,241), Charles G. Burkett ($535,000), Jim L. Hughes ($3,455,000),
       and Larry Martin ($100,000).

       The Committee established target payouts and performance criteria for
       2005 annual cash bonuses under the shareholder-approved 2002 Management
       Incentive Plan (MIP). For the executive officers other than the line
       business unit heads (Gerald L. Baker, Charles G. Burkett, Jim L. Hughes,
       and Larry Martin), target bonuses were established ranging from 60% to
       125% of base salary, and maximum bonuses are 150% of target. The primary
       criterion for determining final bonuses will be earnings per share growth
       for 2005. For the line business unit heads, bonuses were established as a
       percentage of a measure of applicable business unit pretax income, all in
       accordance with existing arrangements.

Pursuant to Instruction B.4. to Form 8-K and applicable regulations and
releases, forms of documents, and descriptions of arrangements, related to the
foregoing will be filed as exhibits to the registrant's next Form 10-K.
