NOTE 6 - STOCK-BASED COMPENSATION

Stock Option Plans

The Company has a 2002 Stock Option Plan, a 2005 Stock Option Plan, a 2008 Stock Option Plan, and a 2011 Stock Option Plan for the benefit of certain directors, officers, and key employees. Under these plans, 4,100,000 shares of authorized common stock have been reserved for issuance pursuant to grants approved by the Compensation and Stock Option Committee of the Board of Directors. Stock options granted under these plans have a maximum duration of 10 years, may be subject to certain vesting requirements, which are generally one year for directors and five years for officers and key employees, and are priced at the market value of the Company's common stock on the date of grant of the option. At June 30, 2012, there were 1,459,138 shares available for grant under the plans.

Stock based compensation is recognized as provided under FASB ASC Topic 718-10 and FASB ASC Topic 505-50. FASB ASC Topic 718-10 requires all share-based payments to employees, including grants of employee stock options, to be recognized as compensation expense over the requisite service period (generally the vesting period) in the consolidated financial statements based on their fair values. The impact of forfeitures that may occur prior to vesting is also estimated and considered in the amount recognized. Stock option compensation is recognized as an expense over the unvested portion of all stock option awards granted based on the fair values estimated at grant date in accordance with the provisions of FASB ASC Topic 718-10. The Company has applied the Black-Scholes valuation model in determining the fair value of the stock option awards. Compensation expense is recognized only for those options expected to vest, with forfeitures estimated based on historical experience and future expectations.

There were no option grants during the quarters ended June 30, 2012 or June 30, 2011.

Option activity for the three months ended June 30, 2012 was as follows:

	Shares			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term		Aggregate Intrinsic Value

Options outstanding, beginning of year		1,041,500		$	37.95
Granted		-			-
Exercised		(67,450	)		27.35
Forfeited		(6,400	)		48.85
Expired		(300	)		43.04
Options outstanding, end of period		967,350		$	38.61		7.02	$	26,708,037
Options exercisable, end of period		224,040		$	27.58		3.89	$	8,563,013

The aggregate intrinsic value reflected in the table above represents the total pre-tax intrinsic value (the difference between the closing stock price on June 30, 2012 and the exercise price, multiplied by the number of in-the-money options) that would have been received by option holders had all option holders exercised their options as of June 30, 2012. This amount will change as the stock's market price changes. The total intrinsic value of options exercised during the periods ended June 30, 2012 and 2011 was as follows:

	June 30,		June 30,
	2012		2011
Three months ended	$	2,739,530	$	1,576,465

As of June 30, 2012 total unrecognized stock-based compensation expense related to non-vested stock options amounted to approximately $10.9 million, which is expected to be recognized over a weighted-average period of approximately 3.6 years.
