Single Source Playmaker Supplier

The Company currently purchases its Playmakers from an unaffiliated Taiwanese manufacturer subject to the terms of a supply agreement dated April 23, 2007 with a term that automatically renews for one year periods.  The Company currently does not have an alternative source for its playmaker devices.  Management believes other manufacturers could be identified to produce the Playmakers on comparable terms.  A change in manufacturers, however, could cause delays in supply and may have an adverse effect on the Company’s operations.  As of June 30, 2011 and December 31, 2010, approximately $173,000 and $127,000, respectively, were included in accounts payable or accrued expenses for this supplier.
