The Purchase Plan allows employees to purchase common shares through payroll deductions of up to 15% of their eligible compensation.  Such deductions will accumulate over a six-month accumulation period without interest.  After such accumulation period, common shares will be purchased at a price equal to 85% of the fair market value per share on either the first day of the offering period or the last date of the accumulation period, whichever is less.  The maximum number of shares that may be purchased by a participant on any purchase date may not exceed 875 shares for a total of 3,500 shares per a 24-month offering period.  In addition, no participant may purchase more than $25,000 worth of common stock in any one calendar year period.  No more than 300,000 common shares may be purchased by all participants on any purchase date.The ESPP is compensatory and results in compensation expense.
