The Board has delegated to the Compensation Committee the duty of designing and overseeing the Company’s executive compensation program. The Compensation Committee is comprised entirely of independent (pursuant to Nasdaq and SEC rules, and the Company’s own Independence Guidelines) members of the Board.

The Company’s executive compensation program is designed to:

•provide competitive total compensation consistent with job scope, experience, and related skills;

•link bonus opportunities to the Company’s performance;

•grant equity compensation at competitive levels, a significant portion of which is performance-based;

•avoid unnecessary and imprudent risks; and

•attract and motivate talented executive officers and minimize turnover of senior-level Company employees, which the Company believes contributes to the stability and continuity of senior leadership.
