19. Shareholders' Equity Transactions

Equity Transaction

In May 2007, the Company completed the sale of 3,641,909 shares of its common stock at a price of $11.00 per share and warrants to purchase up to 546,283 shares of its common stock at an exercise price of $15.00 per share. This sale was made through a private placement to accredited investors. The warrants are callable by the Company if, among other things, the volume weighted average trading price of the Company's common stock as quoted by Bloomberg L.P. is greater than $22.50 for 10 consecutive trading days. The fair value of the warrants at the date of grant was estimated to be approximately $4.44 per warrant using the Black-Scholes pricing model. The following assumptions were used to calculate the fair value of the warrants: dividend yield of 0%; expected volatility of 40.01%; risk-free interest rate of 4.5766%; and an expected life of five years.

Share Repurchase Program

In March 2010, the Company's Board of Directors authorized a share repurchase program of up to $5,000,000 of the Company's outstanding common stock from time to time in the open market and in private transactions at prices deemed appropriate by management. There is no expiration date governing the period over which the Company can repurchase shares under this program. During July 2010, the Company repurchased 14,400 shares at a total cost of approximately $89,000. The Company's credit agreements currently prohibit such repurchases.
