Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) These shares will vest in four equal annual installments beginning on March 1, 2013.
(2) Grant of restricted Common Stock of the Issuer, pursuant to its 2010 Performance-based Equity Incentive Plan. Vesting of these shares is subject to the satisfaction of both certain service-and performance-based vesting conditions. The amount of 15,692 reported as granted represents the maximum potential achievable award assuming maximum performance attainment in each of the subsequent three years, compared to a "target" award value equivalent to 6,277 shares. If minimal performance conditions are not met, all shares will be returned to the Performance Share Plan. The grant consists of three substantially equal performance measurement periods, and the number of shares in each tranche that ultimately vest is a function of the Issuer's Total Shareholder Return during a given calendar-year period relative to the members of a predetermined peer group of companies, and the satisfaction of applicable service conditions.
(3) This represents shares withheld by the Registrant in respect of payment of withholding tax liability incurred upon the vesting of restricted shares from grants made in two prior years which vested on March 1, 2012
(4) This represents shares withheld by the Registrant in respect of payment of withholding tax liability incurred upon the vesting of restricted shares from a grant made in a prior year which vested on March 2, 2012.
(5) These securities are owned and controlled by a family limited partnership for the benefit of immediate family members of the Reporting Person and may be deemed to be beneficially owned by the Reporting Person.
 
Remarks:
In February 2012, the Compensation Committee of the Board of Directors effected its determinations for executive officer compensation for 2012, including with respect to equity and equity-linked instruments.  The Committee determined that equity awards to senior management should be comprised of 75% restricted stock under the Issuer's amended and restated 2001 Stock Incentive Plan, and 25% performance-based restricted stock issued under the Issuer's 2010 Performance-based Equity Incentive Share Plan.  The restricted stock awards vest in equal annual installments over four years beginning on March 1, 2013, and the performance-based restricted stock awards vest at the end of three years on December 31, 2014 and are subject to three annual performance measurement periods.
