16.	Stockholder Rights Plan

On June 19, 2000, our Board adopted a stockholder rights plan under which holders of common stock as of June 30, 2000 received preferred stock purchase rights as a dividend at the rate of one right per share. As amended in June 2004 and July 2006, each right initially entitles its holder to purchase one one-hundredth of a Series A preferred share at $175.00, subject to adjustment. Upon becoming exercisable, each right will allow the holder (other than the person or group whose actions have triggered the exercisability of the rights), under alternative circumstances, to buy either securities of the Company or securities of the acquiring company (depending on the form of the transaction) having a value of twice the then current exercise price of the rights.

With certain exceptions, each right will become exercisable only when a person or group acquires, or commences a tender or exchange offer for, 15% or more of our outstanding common stock. Rights will also become exercisable in the event of certain mergers or asset sales involving more than 50% of our assets or earning power. The rights will expire on June 15, 2014, unless redeemed or exchanged. Our Board reviews the plan periodically to determine if the maintenance and continuance of the plan is still in the best interests of the Company and its stockholders.
