Under the 1997 Plan and 2003 Plan, PSB has granted non-qualified options to certain directors, officers and key employees to purchase shares of PSB's common stock at a price not less than the fair market value of the common stock at the date of grant.

The Company has calculated the fair value of each option grant on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions used for grants during the three months ended March 31, 2010: a dividend yield of 3.4%; expected volatility of 17.5%; expected life of five years; and risk-free interest rates of 2.4%. No options were granted during the three months ended March 31, 2011.&lt;/p&gt;
