F1: Represents shares of common stock acquired upon conversion of a like number of deferred stock units, at the end of reporting person's elective deferral period, exempt pursuant to Rule 16b-3.

F2: Totals shown include the originally issued DSUs plus the cumulative additional DSUs issued in respect of deemed dividend distributions on the DSUs following each dividend date.

F3: Pursuant to registrant's 2006 Equity Incentive Plan, as amended, in respect to the reporting person's continuing service as a non-employee director and as a portion of his annual retainer, the reporting person on June 1 was granted an exempt award of Deferred Stock Units ("DSUs"). The number of DSUs granted was determined by dividing $90,000 by the closing price of registrant's common stock on the day preceding the grant date.

F4: The reporting person, by prior election, chose to receive his common stock, when converted from DSUs, at the expiration of one year following the grant date.

F5: Each whole DSU represents registrant's unsecured and unfunded obligation, upon the expiration of the reporting person's deferral period election, to convert and issue to the reporting person one share of registrant's common stock for each DSU. The DSUs are 100% vested on the grant date.
