Effective as of the 2007 Annual Meeting of Shareholders, non-employee directors shall receive the following non-cash compensation:

	•		An initial grant of an option to purchase 50,000 shares of Common Stock upon election to the Board of Directors vesting with respect to 16,667 shares after the conclusion of the first year and the remainder vesting in equal monthly increments over a period of two years

The annual grant will vest in equal monthly increments over a period of one year
	•		Each director shall have 12 months to exercise his or her options following termination of Board service for any reason
	•		Grants may also be made to non-employee directors on a discretionary basis, subject to compliance with the Company’s corporate governance codes and policies

In the interest of good corporate governance and to further align the interests of members of the Board of Directors with the Company’s stockholders, the Nominating and Corporate Governance Committee of the Board of Directors has adopted stock ownership guidelines for directors. Pursuant to these guidelines, if a Director exercises a stock option, it is expected that such Director would, from such option exercise, maintain ownership of at least a number of shares equal to twenty percent (20%) of the net value of the shares acquired (after deducting the exercise price and taxes). In the case of shares acquired upon the exercise of a stock option, each Director is expected to hold such shares for nine months after termination of his or her service on the Board of Directors.
